[0002] With the advent of the post-hydropower station era, many hydropower stations have been in operation for decades, and multiple hydraulic structures have defects such as leakage, concrete aging, and pits. In order to ensure the normal operation and use of hydraulic structures and the safe and stable operation of water conservancy facilities, it is usually necessary to inspect and repair hydraulic structures such as reservoirs, dams, gates, water diversion channels, and hydropower stations. The maintenance time is usually during the dry season when the water flow is small. In order to facilitate the maintenance of hydraulic structures such as the bottom plate and side walls of the discharge structure, it is usually necessary to close the gates for pumping water to create dry land maintenance conditions. The existing pumping is directly pumped with a pump, but for areas with large pumping volume and personnel cannot normally enter the pumping area, pumping is difficult and requires a pumping platform. The artificially built pumping platform cannot be moved, the scope of use is limited, and the practicality is not strong. Utility Model Content

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment: A pumping platform for maintenance of hydraulic structures, such as Figure 1-5 As shown, it includes a floating platform 1, which is towed and moved by four traction ropes. The traction ropes are connected to the concrete base surface through anchors. The floating platform 1 can be moved by adjusting the anchor positions. The floating platform 1 includes an upper plate body 2, a lower plate body 3 and a connector 4. A "cross"-shaped cavity 5 is arranged in the middle of the floating platform 1 to reduce the weight of the floating platform 1. An inflatable floating bag 6 is evenly arranged on the outside of the "cross"-shaped cavity 5. An arc cover 7 is symmetrically arranged on both sides of the edge of the "cross"-shaped cavity 5. An inverted triangular groove 8 is arranged in the middle of the arc cover 7. A clamping block 9 matching the groove 8 is arranged on the outside of the inflatable floating bag 6. The inflatable floating bag 6 and the arc cover 7 are clamped by the clamping block 9 and the inverted triangular groove 8, which is convenient for disassembly and can improve the buoyancy of the floating platform 1. 1-2 groups of support columns 10 are symmetrically arranged on the upper end of the upper plate body 2. Reinforcement columns 11 are arranged on both sides of the support column 10 to improve the supporting capacity of the support column 10. A cross frame 12 is arranged on the upper part of each group of support columns 10. The position of the cross frame 12 is lower than the top of the support column 10. A reinforcing frame 13 connected to the cross frame 12 is symmetrically arranged on the top of the support column 10. A triangle is formed between the reinforcing frame 13 and the cross frame 12, so that the connection between the cross frame 12 and the support column 10 is more secure. A water pump 15 is arranged at the end of the cross frame 12 through an electric hoist 14. There are four water pumps 15 to improve the pumping efficiency. A hook 16 is arranged at the end of the cross frame 12. The electric hoist 14 is connected to the hook 16. The electric hoist 14 is connected to the water pump 15. A water surface float 17 is arranged on the periphery of the water pump 15. The electric hoist 14 can lift and lower the water pump 15. The position of the water pump is adjusted according to the water depth. In order to prevent the water pump from being immersed too deeply in the water and causing water to enter the motor to affect the use of the water pump, the water surface float 17 plays a positioning role. During use, the position of the water pump 15 immersed in the water shall not be higher than the position of the water surface float 17. The water inlet 18 of the water pump 15 is located at the lower end, and the water outlet 19 is connected to the water outlet pipe 20. The water outlet pipe 20 includes a plurality of spliced pipes connected by flanges. The water inlet 18 is always immersed in water to facilitate pumping. The spliced water outlet pipe 20 can adjust the length to facilitate pumping water from different positions, and is highly practical.
