Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a siphon drainage device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can water flow be controlled and flood disasters be prevented. In dam drainage projects, siphon drainage devices are often used to control water level drainage. In the prior art, siphon drainage devices are often used to control water level in dam drainage projects. However, in the process of siphon drainage, traditional siphon drainage devices are prone to debris entering the connecting pipe and causing blockage, which makes the entire device unable to operate normally and affects the water conservancy drainage work.

[0003] A Chinese patent discloses a siphon drainage device for water conservancy projects (authorization announcement number CN221030584U). The patented technology achieves the effect of filtering debris in the water by setting a connecting box and a filter hole, thereby maintaining the connection of the connecting pipe. By setting a driving motor, a reciprocating screw rod, a slider, a guide rod, a rectangular frame and an annular cleaning brush and other structures, the effect of cleaning the debris attached to the surface of the filter hole is achieved to prevent the filter hole from being blocked. By setting a connecting rope, an insert block, a mounting groove and a first spring and other structures, the disassembly and assembly of the annular cleaning brush is facilitated, thereby facilitating the removal of the annular cleaning brush with a damaged curling edge.

[0004] However, it has certain disadvantages: its annular cleaning brush can only clean the debris adhered to the surface of the connection box or the softer debris in the filter holes. For the hard debris stuck in the filter holes, such as stones and glass, it cannot be cleaned away by the annular cleaning brush alone, resulting in more and more filter holes blocked by hard objects, which in turn leads to poor drainage. Utility Model Content

[0025] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a siphon drainage device for water conservancy projects includes a siphon tube 1. A sealing valve 2 is installed at the right end of the siphon tube 1, and a filter seat 3 is installed outside the left end of the siphon tube 1. A filter plate 4 is connected through the left side surface of the filter seat 3, and a plurality of filter holes 5 are evenly arranged inside the filter plate 4;

[0026] The entire siphon drainage device is installed on hydraulic structures such as a water conservancy dam 28 for siphon drainage;

[0027] The height of the filter seat 3 is higher than that of the sealing valve 2;

[0028] The sealing valve 2 is an electric control valve. After it is opened, the water on the left side of the water conservancy dam 28 is discharged to the right side through the sealing valve 2 by the siphon principle;

[0029] The filter holes 5 are used to filter debris in the water to prevent it from blocking the siphon tube 1.

[0030] In Figure 1 、 Figure 3 and Figure 4 : A cleaning mechanism 6 is arranged on the upper surface of the filter seat 3. The cleaning mechanism 6 includes a support plate 7. The lower end of the support plate 7 is installed on the upper surface of the filter seat 3. A first motor 8 is installed on the right side surface of the support plate 7, and a support rod 9 is rotatably connected to the left side surface of the support plate 7. Synchronous wheels 10 are installed on the output end of the first motor 8 and the outside of the support rod 9 respectively. A synchronous belt 11 is installed outside the two synchronous wheels 10, and a brush 12 is installed at the left end of the support rod 9;

[0031] A waterproof device can be installed outside the first motor 8; the first motor 8 has self-locking, that is, after power off, the motor shaft cannot rotate;

[0032] When the brush 12 rotates, the right bristles can be close to the left side surface of the filter plate 4 and wipe across the left side surface of the filter plate 4, so as to clean the surface of the filter plate 4 and prevent the filter holes 5 from being blocked.

[0033] In Figure 1 、 Figure 3 、 Figures 5 to 8In the middle: A through-hole mechanism 13 is jointly provided on the upper surface and inside of the filter seat 3. The through-hole mechanism 13 includes a through-hole member 14 and a rotating member 15 that drives the through-hole member 14 to flip. The through-hole member 14 includes two first connecting rods 16 at the front and back. On one side surface of the left end of the first connecting rod 16, a hinge block 17 is rotatably connected. The lower end of the hinge block 17 is installed on the inner lower surface of the filter seat 3. The right ends of the two first connecting rods 16 are jointly installed with a second connecting rod 18. And on the upper surfaces of the two first connecting rods 16, a plurality of third connecting rods 19 are jointly and evenly installed from left to right. On the upper surfaces of the third connecting rods 19, a plurality of through-hole columns 20 are evenly installed. The number of through-hole columns 20 is equal to the number of filter holes 5. The rotating member 15 includes a sealing box 21. The lower end of the sealing box 21 is installed on the upper surface of the filter seat 3. And the sealing box 21 is located on the right side of the cleaning mechanism 6. The upper end of the sealing box 21 is installed with a box cover 22. And a second motor 23 is installed inside the sealing box 21. The output end of the second motor 23 is installed with a mounting rod 24. A mounting rope 25 is wound around the outside of the mounting rod 24. The mounting rope 25 movably passes through the lower surface of the sealing box 21 and the lower surface of the filter seat 3. And one end of the mounting rope 25 is connected to the right side surface of the second connecting rod 18. The outside of the mounting rope 25 is movably attached to a roller 26. The roller 26 is located above the left end of the through-hole member 14. The front and rear ends of the roller 26 are both rotatably connected to a mounting block 27. The upper end of the mounting block 27 is installed on the inner upper surface of the filter seat 3;

[0034] The second motor 23 is connected to a forward and reverse circuit and has self-locking, that is, after power-off, the motor shaft cannot rotate;

[0035] The mounting rope 25 is in a released state in its initial state. When it is retracted, it can drive the through-hole member 14 to rotate upward to a vertical state. At this time, the through-hole column 20 just passes through the filter hole 5, which is used to push out hard objects such as stones stuck in the filter hole 5, avoiding the blockage of the filter hole 5;

[0036] The through-hole columns 20 correspond to the filter holes 5 one by one. And the through-hole columns 20 are cylinders, and their diameters are smaller than the diameters of the filter holes 5. This enables the through-hole columns 20 to penetrate into or move out of the filter holes 5 without contacting the filter plate 4, and no jamming state will occur;

[0037] The density of the through-hole member 14 is greater than that of water. When it is in a horizontal state, it will not rotate to a vertical state due to the buoyancy of water; when the through-hole member 14 is in a vertical state, when the mounting rope 25 is released, the impact force of water is sufficient to knock down the through-hole member 14 and restore it to a horizontal state. Further, a counterweight can be installed on the lower surface of the second connecting rod 18 to make it easier for the vertical through-hole member 14 to return to a horizontal state.

[0038] The working principle of the utility model is as follows: during use, the entire siphon drainage device is installed on the water conservancy dam body 28, with its left end positioned in the water. Then, the sealing valve 2 is opened. Under the action of siphonage, the water on the left side of the water conservancy dam body 28 will be drained to the right side. The filter plate 4 filters the sundries in the water to prevent them from entering the siphon pipe 1 and causing blockage. The first motor 8 drives the support rod 9 to rotate through the synchronous belt 11, and the brush 12 will clean the surface of the filter plate 4, preventing sundries from blocking the filter holes 5 and resulting in unsmooth drainage. Every once in a while, the second motor 23 retracts the installation rope 25, and the through-hole member 14 will rotate upward to a vertical state. The through-hole column 20 penetrates into the filter hole 5 to push out hard objects such as stones stuck in the filter hole 5, preventing blockage of the filter hole 5.

[0039] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the utility model.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
