DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0047] like Figures 1 to 11As shown, a device for repairing surface defects of underwater buildings comprises four groups of underwater positioning components 1, which are clamped and fixed to the sides of the underwater building 2; a defect covering mechanism 3 is fixedly installed on the four groups of underwater positioning components 1; the defect covering mechanism 3 comprises a defect covering box 301, a filling cavity 302 is provided inside the defect covering box 301, an injection nozzle 304 and a discharge nozzle 303 connected to the filling cavity 302 are respectively installed at the upper and lower parts of the defect covering box 301, and ball valves 305 are rotatably installed inside the injection nozzle 304 and the discharge nozzle 303; positioning seats 306 used in conjunction with the underwater positioning components 1 are respectively fixedly installed at the four corners of the defect covering box 301, and under the joint action of the four groups of underwater positioning components 1, the defect covering box 301 is sealed and fitted to the surface of the underwater building 2, and the defective parts 4 on the surface of the underwater building 2 are all located in the filling cavity 302. After the device is installed, the water in the filling cavity 302 is first discharged through the discharge nozzle 303, and then concrete is poured into the filling cavity 302 through the injection nozzle 304, thereby covering the defective part 4 in the filling cavity 302, thereby preventing the defective part 4 from being further corroded. It is very convenient when working underwater.

[0048] like Figures 5 and 6 As shown, a conversion tank 308 is mounted at the mouth of the discharge nozzle 303. The capacity of the conversion tank 308 is greater than that of the filling chamber 302. When the defect covering box 301 is installed on the underwater structure 2, water is present in the filling chamber 302. To drain the water from the filling chamber 302, the conversion tank 308 is connected, and the ball valve 305 in the discharge nozzle 303 is opened. The water in the filling chamber 302 then flows into the conversion tank 308 under the action of gravity, thereby completely draining the water from the filling chamber 302.

[0049] like Figures 7 and 8 As shown, a conduit 309 is installed at the mouth of the injection nozzle 304. After the water in the filling cavity 302 is drained, the conduit 309 is connected and the ball valve 305 at the injection nozzle 304 is opened. At this time, concrete is poured into the filling cavity 302 through the conduit 309, thereby pouring concrete into the filling cavity 302 to cover the defective portion 4 in the filling cavity 302 and prevent the defective portion 4 from further corrosion.

[0050] like Figure 6 、 Figure 8 As shown, the discharge nozzle 303 and the conversion tank 308, as well as the injection nozzle 304 and the conduit 309, are plug-fitted together, and sealing rings 310 are installed at the plug-in locations. To ensure the sealing of the plug-in connections, the installation of sealing rings 310 enhances the sealing between the discharge nozzle 303 and the conversion tank 308, and between the injection nozzle 304 and the conduit 309.

[0051] like Figures 3 and 4 、 Figures 9 to 11As shown, the injection nozzle 304 and the discharge nozzle 303 are both threadedly sealed with a nut 311. A locking pin 312 is fixed inside the nut 311, and a slot 313 is provided on the valve core of the ball valve 305 for the locking pin 312. When the nut 311 is fitted onto the injection nozzle 304 or the discharge nozzle 303, the locking pin 312 fits neatly into the slot 313. To further enhance the seal during subsequent reuse, the nut 311 is added, and the locking pin 312 attached to the nut 311 locks the ball valve 305, which is now in the closed state.

[0052] like Figure 4 As shown, the filling cavity 302 is supported by multiple evenly distributed pillars 314. In order to further enhance the support effect within the filling cavity 302, multiple pillars 314 are provided to support the filling cavity 302, thereby enhancing the stability and reliability of the filling cavity 302 after being cast.

[0053] like Figure 4 As shown, a sealing strip 315 arranged around the filling cavity 302 is bonded and fixed on the contact surface between the defect covering box 301 and the underwater building 2. In order to ensure the sealing, the sealing strip 315 is added to strengthen the sealing between the defect covering box and the surface of the underwater building 2.

[0054] like Figures 12 to 13 As shown, the underwater positioning assembly 1 includes a positioning frame 101, with a clamping seat 102 fixed to one end of the positioning frame 101. A screw 103 is rotatably mounted on the end of the positioning frame 101 away from the clamping seat 102. The end of the screw 103 is fixed to a clamping seat 2 104 that is aligned with the clamping seat 102. In order to achieve the clamping and fixing of the underwater positioning assembly 1 on the side of the underwater structure 2, the defect covering mechanism 3 can be firmly fixed to the surface of the underwater structure 2 by rotating the screw 103, under the joint clamping of the clamping seat 102 and the clamping seat 2 104.

[0055] like Figure 3 、 Figures 12 to 13 As shown, the surface of the positioning seat 306 is provided with a limiting groove 307, and the clamping seat 2 104 is clamped in the limiting groove 307. In order to ensure the clamping effect, the limiting groove 307 is provided, and the clamping seat 2 104 is located in the limiting groove 307 during clamping, which can greatly improve the reliability of the positioning seat 306 after being clamped.

[0056] The working principle of this utility model:

[0057] Before use, the device must be installed. First, the four underwater positioning assemblies 1 are installed and secured. During installation, by rotating the screw 103, the underwater positioning assemblies 1 can be fastened to the side of the underwater structure 2, with the clamping of the first clamp 102 and the second clamp 104. Screw 103 is then adjusted to position the positioning seat 306 where the second clamp 104 is located. Screw 103 is rotated again to clamp the second clamp 104 into the limiting groove 307, completing the installation of the defect covering mechanism 3.

[0058] During use, since water will enter the filling chamber 302 during installation, in order to drain the water in the filling chamber 302, after connecting the conversion tank 308, open the ball valve 305 in the discharge nozzle 303. At this time, the water in the filling chamber 302 enters the conversion tank 308 under the action of gravity, thereby completely draining the water in the filling chamber 302. After the water is drained, close the ball valve 305 in the discharge nozzle 303 and remove the conversion tank 308.

[0059] After the water in the filling chamber 302 is drained, the conduit 309 is connected, and the ball valve 305 at the injection nozzle 304 is opened. Concrete is then poured into the filling chamber 302 through the conduit 309. After the pouring is complete, the ball valve 305 at the injection nozzle 304 is closed and the conduit 309 is removed. Since the defective portion 4 in the filling chamber 302 is covered by the poured concrete, further corrosion of the defective portion 4 is prevented, and the surface defect of the underwater structure 2 is repaired.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
