Next to the square holes on the deck, golf stone cannons were quickly assembled, and familiar people were putting the finishing touches on it. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

These golf stone cannons are mounted in their entirety on a circular base with a diameter of three meters, and below the base is a steel ring bent from round steel the thickness of a thumb, which is welded directly to a circular steel plate that is bolted to the deck of a cargo ship.

A section of steel pipe was bolted to the center of the steel ring, and a gear was fixed on the steel pipe by means of a pin stop pin.

Four concave wheels with bearings are installed on the base of the golf stone cannon corresponding to the position of the steel ring, so that the base can move in a circle around the steel pipe on the simple guide rail made of the steel ring, and the bearing and the card groove installed on the bearing steel pipe can rotate flexibly while fixing the stone cannon.

There is a crank on the base, and the gears on the crank are meshed with the gears on the steel pipe, and the person sitting on the stone cannon can control the angle of rotation of the entire stone cannon through the crank on it to adjust the direction of the stone projectile ejection.

There are four pendulums on each gun mount, and each pendulum can reach a weight of 500 kilograms when filled with earth and stones, which can easily catapult about 10 kilograms of pebbles to a distance of about 200 meters.

If the pendulum is all poured with iron sand, the power is greater, but the density of iron sand is three or four times that of soil and stone, and a pendulum has a weight of nearly two tons.

The pendulum is driven by a reduction gear driven by a DC motor, which can reach a frequency of one shot per second at the earliest.

The purpose of using a DC motor is to easily control the transmission frequency by adjusting the voltage and current, and at the same time, it can provide power directly through the backup battery pack, avoiding the impact of unexpected interruptions in the main power.

There is also a spare gear between the motor and the reduction gear, and when all power supply fails, the power of the stone cannon can be switched to manual mode with a lever.

In this mode, four people use the foot pedal at the same time to drive the pendulum to rise, which can also achieve the effect of firing, but the frequency of firing stone projectiles is only about four rounds per minute.

This is the most important long-range attack weapon on this water fortress designed by Wei Minsheng, the ejection distance of two or three hundred meters in the horizontal direction is enough to kill the vast majority of long-range weapons in the world in an instant, and regardless of any armor, the fast-flying pebbles can shock people into serious injuries through the armor with kinetic energy, and there is basically no possibility of survival when hitting the vital point.

The decked cargo hold creates a relatively confined space, leaving only a place in and out of the cargo hold at the bow, which can be accessed by a staircase to the bottom of the original cargo hold.

This confined space was prepared by Wei Minsheng to load the pebble shells fired by the golf stone cannonballs, with a load capacity of 3,000 tons, excluding personnel, decks and other facilities, at least 2,000 tons of stone bullets when fully loaded, enough to support any small battle.

In order to reduce the workload of loading stone bullets, Wei Minsheng even installed a special conveyor belt in the middle of the cargo hold, one end of the conveyor belt is fixed to the cargo ship with a bearing, and the other end of the conveyor belt can be lowered to the riverbed through a hanging rope when the cargo ship docks.

When the power is turned on, the soldiers on both sides of the conveyor belt only need to put the pebbles on the riverbed on the conveyor belt, and the conveyor belt will automatically send the pebbles to the cargo hold, and then distribute the pebbles to the small compartments under the various gun mounts through the conveyor belt in the cargo hold passage.

These stone shells were finally passed through the reels installed in the square holes reserved on the deck, barrel by barrel to the side of the stone cannon mount, so as to achieve the purpose of continuous ammunition supply.

Eight high-pressure water cannons with a maximum range of 60 meters were also installed in the four directions of the front and rear of the platform, one in the front and one on the front and three on each side, which could be used to extinguish fires and destroy ships.

The water column with a range of 60 meters can also prevent any form of gang jumping, and under the impact of such a large water current, it already has the ability to cause damage to the human body, and it is impossible for anyone to stand still under the continuous impact of the water current.

In this way, the method of besieging the fireboat upstream was almost ineffective for this water fortress, not to mention that the iron hull would not catch fire, and the wooden fireship leaning over had the ability to sink the fireboat with water, even if it could not be extinguished for a while, under the impact of these high-pressure water cannons.

And water, which is on the Yangtze River, which does not freeze all year round, is really inexhaustible and inexhaustible.

Moreover, this used water eventually returns to the river, and as long as the cargo ship can provide a steady stream of power, it can be invincible.

In order to increase the impact damage ability of the cargo ship, the bow position also made a ramming angle with three steel pipes, and the two steel pipes below the ramming angle are connected with the thick hull of the lower part of the bow, which can swing up and down, and the sharp corners cut out by the cutting machine are not easy to mess with at first glance.

The steel pipe itself does not bear much of the impact force, but by changing the length of the steel pipe, the height of the collision angle can be adjusted, so that the collision angle can produce the greatest damage to the enemy ship.

With this ramming angle, coupled with two rows of golf stone cannons, eight high-pressure water cannons and a hard hull, it was simply armed to the teeth by Wei Minsheng.

The converted cargo ship is truly invincible in the long and near battles on the Yangtze River in this era, which is enough to deter any armed forces on the water, and even has a certain degree of threat to some cities on the shore.
