Abstract
Description
Technical Field
[0001] The utility model relates to the field of maintenance construction of hydraulic structures, in particular to a tetrahedron dumping platform for maintaining hydraulic structures. Background Technique
[0002] With the advent of the post - hydropower - station era, after decades of operation of many hydropower stations, multiple hydraulic structures have defects such as leakage, concrete aging, and scouring pits. 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 repair large scouring pits in the concrete of hydraulic structures. To reduce the damage to the concrete floor of hydraulic structures during high - head and large - flow flood discharges and protect the safety of the underlying concrete, for large - volume concrete scouring pits, concrete secondary pouring is usually used for maintenance. However, the re - poured concrete requires pumping to create dry - land construction conditions, and it is very difficult to ensure that the combination with the original base surface and the anti - impact effect are better than the original concrete. For large concrete scouring pits, tetrahedrons are usually dumped to improve the anti - impact ability. When dumping tetrahedrons without pumping, it is very difficult to ensure that the tetrahedrons are dumped to the accurate position in the area where the crane cannot operate. Therefore, it is very crucial to design a tetrahedron dumping platform suitable for maintaining hydraulic structures. Content of the Utility Model

Detailed Embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment: A tetrahedron filling platform for the maintenance of hydraulic structures, asFigures 1-5 As shown in the figure, it includes a floating platform 1. A fence 6 is provided on the floating platform 1 to ensure the safety protection of the operators on the floating platform 1 is in place. The floating platform 1 is towed and moved by a towing rope. A tetrahedron filling hole 2 is provided in the middle of the floating platform 1. A gantry 3 striding across the tetrahedron filling hole 2 is provided on the floating platform 1. A hoisting device 4 is provided in the middle above the gantry 3. The hoisting device 4 is an electric winch or an electric hoist. The hoisting device 4 is convenient for hoisting and lowering the tetrahedron. A hook release device 5 is provided at the lower end of the hoisting device 4. The hook release device 5 is of an integral structure. The hook release device 5 includes a suspension hole 7, a counterweight arm 8 and a suspension arm 9. An angle of 60 - 90° is formed between the counterweight arm 8 and the suspension arm 9. A suspension hook 10 is provided at the end of the suspension arm 9. The suspension hook 10 is a hook with an angle of 80 - 90°. The suspension hole 7 is located at the intersection of the suspension arm 9 and the counterweight arm 8. The weight of the counterweight arm 8 is greater than the sum of the weights of the suspension arm 9 and the suspension hook 10. When there is no hoisting, the hook release device is in a natural hanging state with the suspension hole 7 as the center, and the counterweight arm is slightly lower than the suspension arm 9, and the suspension hook is inclined downward. When the suspension hook 10 of the hook release device 5 hangs the tetrahedron, due to gravity, the counterweight arm is basically in a horizontal state, and the suspension arm 9 is basically in a vertical state, which is convenient for hoisting the tetrahedron. When the bottom of the tetrahedron touches the ground, since the downward force of the hook release device decreases, the hook release device automatically returns to the natural hanging state, and under the action of the gravity of the counterweight arm, the suspension hook is inclined downward, that is, automatic hook release is realized. An inflatable buoy 11 is provided on the outside of the floating platform 1 to increase the buoyancy of the floating platform 1. Arc-shaped covers 12 are symmetrically provided on the upper and lower sides of the outer edge of the floating platform 1. An inverted triangular groove 13 is provided in the middle of the arc-shaped cover 12. A clamping block 14 matching the groove 13 is provided on the outside of the inflatable buoy 11. The inflatable buoy 11 is connected to the groove 13 of the arc-shaped cover 12 through the clamping block 14, so that the inflatable buoy 11 is firmly arranged on the outside of the floating platform, and the practicability is strong.
[0021] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
