[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 A ship bottom rust removal device for ship repair in a dock includes an equipment body 10. A water storage tank 101 is provided inside the equipment body 10. Two groups of electric-controlled water pumps 16 are also provided inside the equipment body 10. The water inlet ends of the electric-controlled water pumps 16 are both connected to the water storage tank 101. The water outlet end of one group of electric-controlled water pumps 16 is connected to a connecting pipe 161. The end of the connecting pipe 161 is connected to a second water spray plate 162. The water outlet end of the other group of electric-controlled water pumps 16 is connected to a diverter pipe 151. The diverter pipe 151 includes two water outlet ends, one of which is connected to a cleaning ball 14. A plurality of first water spray holes 141 are opened on the surface of the cleaning ball 14. The other water outlet end is connected to the first water spray plate 15.

[0025] Water is sprayed through the first water spray plate 15 to perform the initial rust removal, and then the waste residue after rust removal is blown away by the cleaning ball 14, and then a secondary cleaning is performed through the second water spray plate 162 to ensure the rust removal effect while blowing away the cleaned rust.

[0026] Among them, the lower surface of the equipment body 10 is fixed with a support plate 17 by bolts, the cleaning ball 14 and the electric water pump 16 are both arranged on the upper surface of the support plate 17, the water outlet end of the cleaning ball 14 is arranged on the lower surface of the support plate 17, the first water spray plate 15 and the second water spray plate 162 both penetrate the lower surface of the support plate 17 and are fixed by the support plate 17. When structural damage occurs, the structure can be disassembled from the bottom for maintenance operations.

[0027] Among them, a limiting sleeve 11 is provided on one side of the equipment body 10, and a water pipe 12 is provided inside the limiting sleeve 11. The water pipe 12 runs through the inside of the water tank 101, and water is passed into the inside of the water tank 101 through the water pipe 12.

[0028] Among them, the cleaning ball 14 includes two parts, the upper cleaning ball 14 is sealed and arranged on the upper surface of the support plate 17, the first water spray hole 141 is arranged on the surface of the lower cleaning ball 14, and mounting plates 142 are arranged on both sides of the cleaning ball 14. The cleaning ball 14 is fixed to the inner wall of the equipment body 10 by bolts passing through the mounting plate 142. The upper part ensures sealing, and the lower part ensures the water spraying effect.

[0029] Among them, a liquid cavity 164 is opened inside the first water spray plate 15 and the second water spray plate 162, and a plurality of second water spray holes 163 are opened at the ends of the first water spray plate 15 and the second water spray plate 162. The liquid cavity is connected to the pipe body at the corresponding position, and water flows through the liquid cavity 164 and is sprayed out from the second water spray holes 163 for cleaning.

[0030] Among them, power wheels 13 are provided at each corner of the upper and lower surfaces of the equipment body 10, and a sealing cover is sealed on the upper end surface of the water tank 101, so that the equipment body 10 can be freely flipped over. When the water spraying structure is at the upper part, the bottom of the ship is cleaned, and when the water spraying structure is at the lower part, the flat structure is cleaned.

[0031] Among them, the water inlet end of the electric water pump 16 is connected to a pipe, which runs through the interior of the water tank 101. The pipe has two water inlets, one of which is set at the lower end surface of the water tank 101, and the other is set at the upper end surface of the water tank 101. The setting of the two water inlets ensures that when the equipment body is turned over, the electric water pump 16 can still pump water from the interior of the water tank 101.

[0032] Among them, both water inlets are provided with branch pipes, and each branch pipe is provided with an electric-controlled water valve 165. The ends of the branch pipes are connected to a water filter head 166. The working conditions of the corresponding branch pipes are controlled by the electric-controlled water valve 165. When the cleaning ball 14 is facing downward, the lower branch pipe works, and when the cleaning ball 14 is facing upward, the upper branch pipe works, and the water filter head 166 filters out the waste residue in the water to avoid the problem of waste residue in the water source inside the water tank 101 causing blockage of the electric-controlled water pump 16.

[0033] After flipping, it is necessary to sense the working status of the specific electric-controlled water valve 165. For this purpose, a rubber sleeve is provided on the outside of the hub of the power wheel 13, and a pressure sensor 21 is provided between the hub and the rubber sleeve. The pressure generated by the power wheel 13 in contact with the ground is used to sense whether the device body 10 is in an upright or inverted state, thereby determining the specific electric-controlled water valve 165 that needs to be opened.

[0034] Working principle: When in use, the working mode can be selected by setting the water spray structure at the top or bottom. When the water spray structure is at the top, the bottom of the ship is cleaned. When the water spray structure is at the bottom, the flat structure is cleaned. The power is output through the electronically controlled water pump 16. The first water spray plate 15 performs the initial rust removal. The cleaning ball 14 sprays high-pressure water guns from all directions of the spherical surface, thereby achieving the purpose of cleaning the waste residue. The second water spray plate 162 performs the final rust removal to clean the waste residue or iron filings that were not completely cleaned in the first operation. It has a simple structure and is easy to operate.

[0035] See also Figure 5 A control system for ship bottom repair and rust removal equipment in a shipyard is also provided, including a control system 20. The control system 20 includes a pressure sensor 21, a positioning module 22, a signal antenna 23, a controller 24, an electric-controlled water pump 16, and an electric-controlled water valve 165. The controller 24 is electrically connected to the pressure sensor 21, the positioning module 22, the signal antenna 23, the electric-controlled water pump 16, and the electric-controlled water valve 165. The number of the pressure sensor 21, the electric-controlled water valve 165, and the electric-controlled water pump 16 are all two.

[0036] Working principle: The control system needs to cooperate with the equipment body 10 to work. After the equipment body 10 is flipped over, the power wheel 13 in contact with the ground will be subjected to pressure, and the pressure will be sensed by the corresponding pressure sensor 21. Each group of pressure sensors 21 corresponds to a group of electric-controlled water valves 165. When the pressure sensor 21 senses a change in gravity, the corresponding electric-controlled water valve 165 opens, and the other electric-controlled water valve 165 is disconnected. When the equipment body is completely flipped over, the operation of the water inlet branch pipe is switched. When in use, the electric-controlled water pump 16 is always turned on by the controller 24, and the electric-controlled water pump 16 is always in working state. The signal antenna 23 and the positioning module 22 always locate the position of the equipment body 10 and transmit the control signal.
