[0029] In this implementation scheme: after checking the public (announcement) number: CN216920241U discloses a discharge mechanism for water conservancy projects. In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the device prevents blockage by rotating the isolation net. Under the continuous flow of water, the debris around the isolation net will accumulate more and more, which will still affect the flow of water." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a salvage component 2 and a limit component 3 are added on this basis.

[0030] More specifically:

[0031] like Figures 1 to 5 As shown;

[0032] Combining the above:

[0033] In order to salvage the debris around the isolation net, the discharge mechanism for water conservancy projects also includes a salvage component 2 arranged on the surface of the dam body 1;

[0034] The salvage assembly 2 includes a fixing groove opened inside the dam body 1, and a motor 21 is arranged inside the fixing groove. The motor 21 is fixedly connected to the dam body 1, and the output shaft of the motor 21 is fixedly connected to a plurality of fixing plates 22, and a plurality of salvage rods 23 are fixedly connected to the surface of each fixing plate 22.

[0035] In this embodiment, when it is necessary to salvage debris, the motor 21 is connected to an external power source and then started, the fixing plate 22 drives the salvage rod 23 to rotate, and the salvage rod 23 scoops up the debris, thus achieving the goal of scooping up the debris.

[0036] Going further:

[0037] In an optional embodiment, each salvage rod 23 is a Y-shaped structure, and one end of the salvage rod 23 away from the fixing plate 22 is fixedly connected with a hook.

[0038] In this embodiment, due to the shape of the fishing rod 23, the sundries picked up by it will be caught, and the water will leak out, reducing the resistance.

[0039] Going further:

[0040] In an optional embodiment, a receiving box 24 is fixedly connected to the surface of the dam body 1, and a plurality of separation rods 25 are fixedly connected to the interior of the receiving box 24. A through groove is opened inside the receiving box 24, and a positioning frame 27 is arranged inside the through groove. The positioning frame 27 is slidably connected to the receiving box 24 through the through groove, and a net bag 26 is fixedly connected to one end of the positioning frame 27 away from the receiving box 24. Each separation rod 25 is a trapezoidal structure, and the position of each separation rod 25 is staggered with the salvage rod 23.

[0041] In this embodiment, when the salvage rod 23 rotates to the inside of the storage box 24, the separation rod 25 will scrape the debris inside the salvage rod 23 into the inside of the storage box 24, so that the salvage rod 23 can be used again. The debris entering the storage box 24 will eventually enter the inside of the net bag 26, thereby achieving collection.

[0042] Going further:

[0043] In an optional embodiment, it further includes a limiting component 3 disposed on the surface of the containing box 24;

[0044] The limiting assembly 3 includes a fixed block 31 fixedly connected to the surface of the accommodating box 24, a through hole is provided inside the fixed block 31, and an insertion rod 32 is arranged inside the through hole, the insertion rod 32 is slidably connected to the fixed block 31 through the through hole, a plug hole 34 is provided on the surface of the positioning frame 27, the plug rod 32 is inserted inside the plug hole 34, a tension spring 33 is sleeved on the surface of the plug rod 32, and the two ends of the tension spring 33 are respectively fixedly connected to the plug rod 32 and the fixed block 31.

[0045] In this embodiment: when the interior of the net bag 26 is full, the insertion rod 32 is pulled upward until it is pulled out from the interior of the hole 34, and the net bag 26 can be removed. When installing a new net bag 26, the positioning frame 27 is inserted into the interior of the accommodating box 24, and the insertion rod 32 is released. The tension spring 33 will insert the insertion rod 32 into the interior of the hole 34 due to its elastic potential energy, thereby realizing the disassembly and assembly of the net bag 26.

[0046] It should be noted that after installation, the tension spring 33 is always in an elastically tightened state, so that it can operate normally when the insertion rod 32 is loosened.

[0047] The working principle and use process of the utility model are as follows: when it is necessary to salvage debris, the motor 21 is connected to an external power source and then started, the fixing plate 22 will drive the salvage rod 23 to rotate, and the salvage rod 23 will scoop up the debris, thus realizing the scooping of the debris. Due to the shape of the salvage rod 23, the debris picked up by it will be caught, and water will leak out, reducing resistance. When the salvage rod 23 rotates to the inside of the receiving box 24, the separation rod 25 will scrape the debris inside the salvage rod 23 into the inside of the receiving box 24, so that the debris can be salvaged. The salvage rod 23 can be used again, and the debris entering the storage box 24 will eventually enter the net bag 26, thereby achieving collection. When the net bag 26 is full, the insertion rod 32 is pulled upward until it is pulled out from the inside of the socket 34, and the net bag 26 can be removed. When installing a new net bag 26, the positioning frame 27 is inserted into the storage box 24, and the insertion rod 32 is released. The tension spring 33 will insert the insertion rod 32 into the inside of the socket 34 due to its elastic potential energy, thereby achieving the disassembly and assembly of the net bag 26.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
