[0037] Definitions of relevant terms involved in this invention:

[0038] (1) High-strength steel: Steel with a yield strength between 390 and 690 MPa.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig. 9As shown, a motorized water construction platform provided by the present invention includes a main frame 1 and a driving assembly 2 installed at the bottom of the main frame 1 and capable of driving the main frame 1 to move forward or turn. The main frame 1 is a steel frame with a rectangular parallelepiped structure, and a plurality of rectangular through holes are opened on the top thereof, which has sufficient strength and rigidity, and the rectangular through holes can reduce its mass. A power supply 7 for supplying power to all electrical components is also provided on the top of the main frame 1. The power supply 7 is electrically connected to each second motor in the driving assembly 2, each telescopic member 401 in the telescopic assembly 4, each first motor in the positioning assembly 6, and each electric pump 6044 of the underwater hydraulic device 604, respectively.

[0043] like Figure 1 , Figure 2 , Figure 3 , Fig.12As shown, the positioning assembly 6 includes a plurality of winches 601 symmetrically arranged on the front and rear sides of the main frame 1.

The underwater hydraulic device 604 includes a vertical hollow cylinder 6041 fixedly connected to the main frame 1, a piston 6042 that can slide up and down is slidably installed in the hollow cylinder 6041, and a piston seal ring is installed on the piston 6042 to prevent the hydraulic oil in the hollow cylinder 6041 from leaking from the gap between the piston 6042 and the inner wall of the hollow cylinder 6041.

A drain pipe 6045 is installed at the bottom of the hollow cylinder 6041, and the drain pipe 6045 is connected to the water chamber. The electric pump 6044 adjusts the internal pressure of the oil chamber by delivering or extracting hydraulic oil, driving the piston 6042 to perform piston movement. The displacement of each underwater hydraulic device 604 can be controlled by adjusting the frequency of delivering and extracting oil by the electric pump 6044.

[0044] The parts of the device that need to contact with water are sprayed with epoxy paint, polyurethane paint, inorganic zinc-rich paint or chlorinated rubber paint with protective effect to form a protective layer.

[0045] The working principle of the present invention is as follows: the size of the mobile water construction platform is designed according to actual engineering needs, and the components are directly assembled by the factory after processing, and the complete mobile water construction platform is provided to various users.

[0046] After the user moves the mobile water construction platform to the construction water area, the mobile water construction platform is placed in the water. Under the action of the multiple buoyancy boxes 501 and the multiple buoys 502, the mobile water construction platform will float on the water after entering the water, and the equipment is moved to the support plate 303. At this time, water has entered the drainage pipe 6045 and even entered the water cavity.

[0047] Under the control of the main controller, the four second motors are started, the output shafts of the second motors rotate, driving the first gear to rotate, the first gear drives the second gear to rotate through the chain, the second gear drives the central shaft to rotate, thereby driving the spiral wheel 201 to rotate, the thrust belt 202 rotates with the rotation of the spiral wheel 201, pushing the water flow, so that the mobile water construction platform moves forward. If you want to turn right, increase the speed of the second motor on the right and reduce the speed of the second motor on the left to make the mobile water construction platform turn right. If you want to turn left, reduce the speed of the second motor on the right and increase the speed of the second motor on the left to make the mobile water construction platform turn left.

[0048] After the mobile water construction platform reaches the predetermined position, the main controller controls the four second motors to stop working and controls the four first motors to start. The output shafts of the first motors rotate to drive the rotating shaft to rotate. The cable 602 gradually moves away from the surface of the rotating shaft, and the gravity anchor 603 gradually descends until it is released to the bottom of the water. Then the first motor is controlled to stop working, so that the gravity anchor 603 stays at this position, completing the preliminary positioning of the mobile water construction platform. The main controller controls the electric pumps 6044 of each underwater hydraulic device 604 to start. If the electric pump 6044 draws hydraulic pressure from the oil tank through the first pipeline, The oil is then sent into the oil chamber through the second pipe. After the hydraulic oil enters the oil chamber, it generates pressure on the piston 6042. The piston 6042 slides downward under pressure, the telescopic rod 6043 gradually extends, and the water in the water chamber is squeezed downward and discharged from the drain pipe 6045 into the water area. If the electric pump 6044 extracts the hydraulic oil from the oil chamber through the second pipe and then delivers it to the oil tank through the first pipe, the hydraulic oil in the oil chamber decreases, a negative pressure is generated in the oil chamber, the piston 6042 slides upward, the telescopic rod 6043 gradually shortens, the water in the water chamber increases, and more water flows into the water chamber from the drain pipe 6045. According to the hydrological environment where the construction platform is located, the displacement is adjusted through the above process. By starting the electric pump 6044 of the underwater hydraulic device 604 at different positions, the drainage direction can be adjusted. By adjusting the displacement and drainage direction, the wave force can be balanced, and the precise positioning of the mobile water construction platform is completed. After positioning is completed, when the water flow hits the mobile water construction platform, the buoy 502 will rotate to reduce the impact of the water flow on the mobile water construction platform. The water construction platform built with a floating crane is easily affected by adverse weather conditions and water waves, and has poor safety. The mobile water construction platform can reduce the impact of water waves through the buoy 502, thereby improving the safety of the mobile water construction platform.

[0049] After positioning is completed, the main controller controls the telescopic ends of each telescopic member 401 to start extending synchronously, so that the support plate 303 gradually rises until the equipment reaches the specified construction height, so that the telescopic ends of each telescopic member 401 are maintained in this state and construction begins.

[0050] After the construction is completed, the main controller controls the telescopic ends of each telescopic member 401 to begin to shorten synchronously, and the height of the support plate 303 gradually decreases until it returns to the initial state. Then, the output shaft of the first motor is controlled to reverse, driving the rotating shaft to reverse and recover the cable 602, so that the gravity anchor 603 gradually rises back to the initial position, and controls the displacement and drainage direction of each underwater hydraulic device 604. The four second motors are controlled to start, and the speed of each second motor is controlled according to demand to complete the forward and steering operations, and the mobile water construction platform is manipulated to move to the recovery position, unload the equipment, and recover and store the mobile water construction platform, waiting for the next use.

[0051] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
