However, when the filter device is lowered and reset, the bottom of the filter device may be blocked by impurities in the river, causing the filter device to be unable to fit tightly against the gate structure, affecting the filtering effect. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide a new anti-clogging water conservancy gate filter device in order to solve the above-mentioned problems, so as to solve the problem in the prior art that when the filter device is lowered and reset, the bottom of the filter device may be blocked by impurities in the river, resulting in the filter device being unable to fit tightly against the gate structure, affecting the filtering effect.

[0007] (II) Technical solution

[0008] The utility model is implemented through the following technical scheme: a new anti-blocking hydraulic gate filtering device, including a gate shell, a gate plate and a hydraulic telescopic rod, a filter mesh is arranged on one side of the gate plate, a first elastic box and a second elastic box are arranged on the other side of the gate plate, a guide bend is fixedly connected between the first elastic box and the second elastic box, one end of the guide bend passes through the gate shell and extends to the bottom of the filter mesh, one end of the guide bend is fixedly connected to a telescopic tube, the top of the telescopic tube is fixedly connected to a supporting top plate, and a rubber box is fixedly connected to the side of the filter mesh away from the gate plate.

[0009] Preferably, a top groove is provided on the top of the rubber box, and one side of the rubber box is configured as a curved surface.

[0010] Preferably, an inner groove is provided at the bottom of the inner cavity of the gate housing, the telescopic tube and the supporting top plate are both arranged inside the inner groove, and the bottom of the telescopic tube is fixedly connected to the gate housing.

[0011] Preferably, a disassembly channel is provided on the top of the gate housing, a sealing block is fixedly connected to one side of the filter mesh, the sealing block and the top of the filter mesh both pass through the disassembly channel, the filter mesh and the sealing block block the disassembly channel to ensure the sealing inside the gate housing.

[0015] The utility model provides a novel anti-blocking water conservancy gate filtering device, which has the following beneficial effects:

[0016] 1. In the new anti-blocking hydraulic gate filtering device, after the filter mesh leaves the inside of the gate shell, the top of the telescopic tube loses its obstruction, and the force required for the expansion of the telescopic tube is less than the force required for the expansion of the first elastic box. Therefore, the gas inside the first elastic box enters the telescopic tube through the diversion elbow, so that the telescopic tube pushes the top support plate fixedly connected to the top to move up, and the top support plate with one side heavier and the other side lighter will tilt. At this time, the telescopic tube and the top support plate cooperate to prevent the impurities and garbage at the bottom of the gate shell cavity from clogging the track of the filter mesh moving down and resetting, ensuring that the bottom of the filter mesh can be smoothly inserted into the inner groove opened at the bottom of the gate shell cavity, avoiding the situation where the filter mesh cannot be tightly attached to the gate shell.

[0017] 2. This new anti-blocking water conservancy gate filtering device, when it is necessary to disassemble the filter mesh for cleaning and dredging, controls the gate plate to move downward to block the inside of the gate shell, and the gas stored in the second elastic box enters the first elastic box fixedly connected to the other side of the diversion elbow, causing the first elastic box to expand, and the pneumatic cylinder works to push the transmission cross plate fixedly connected at one end, and one end of the square plate is inserted into the inside of the clamping frame fixedly connected to the top of the first fixed frame. When the working hydraulic telescopic rod pushes the transmission plate fixedly connected to the top to move up, the transmission plate drives the first fixed frame to move up through the square plate, so that the filter mesh fixedly connected to the first fixed frame moves up and leaves the gate shell.

[0018] 3. The new anti-blocking water conservancy gate filter device has an elastic rubber box that blocks some impurities and ejects them, sharing part of the work for the filter mesh to avoid the filter mesh being completely blocked. The gate shell, gate plate, filter mesh and other structures constitute the water conservancy gate to release water with the minimum water flow. A top groove is provided on the top of the rubber box. After the impurities filtered and intercepted by the filter mesh fall to the top of the rubber box, they move away from the filter mesh along the curved surface of the rubber box, and some smaller impurities enter the rubber box, which has the effect of collecting the other part of the garbage.

[0025] The embodiment of the utility model provides a novel anti-blocking hydraulic gate filtering device.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a gate shell 1, a gate plate 2 and a hydraulic telescopic rod 13, a filter mesh 9 is arranged on one side of the gate plate 2, a first elastic box 4 and a second elastic box 5 are arranged on the other side of the gate plate 2, a guide elbow 3 is fixedly connected between the first elastic box 4 and the second elastic box 5, one end of the guide elbow 3 passes through the gate shell 1 and extends to the bottom of the filter mesh 9, one end of the guide elbow 3 is fixedly connected to a telescopic pipe 7, the top of the telescopic pipe 7 is fixedly connected to a supporting top plate 8, and a rubber box 10 is fixedly connected to the side of the filter mesh 9 away from the gate plate 2.

[0027] When the utility model is in use: a rubber box 10 is fixedly connected to the bottom of the side of the filter mesh 9 away from the gate plate 2. The elastic rubber box 10 has the effect of blocking and ejecting a part of the impurities, sharing part of the work for the filter mesh 9, and avoiding the situation where the filter mesh 9 is completely blocked. The gate shell 1, the gate plate 2, the filter mesh 9 and other structures constitute a hydraulic gate that can release water with a minimum water flow. A top groove 12 is provided on the top of the rubber box 10. After the impurities filtered and intercepted by the filter mesh 9 fall to the top of the rubber box 10, they move away from the filter mesh 9 along the curved surface of the rubber box 10, and a part of the smaller impurities enter the rubber box 10, which has the effect of collecting another part of the garbage.

[0028] An inner groove 6 is provided at the bottom of the inner cavity of the gate housing 1, and a telescopic tube 7 and a supporting top plate 8 are both arranged inside the inner groove 6. The bottom of the filter mesh 9 extends into the inner groove 6 and contacts the supporting top plate 8. The telescopic tube 7 fixedly connected to the gate housing 1 is fixedly connected to a diversion elbow 3, and one end of the diversion elbow 3 extends to the inside of the gate housing 1 away from the side of the filter mesh 9, such as Figure 2 As shown, the second elastic box 5 to which the diversion elbow 3 is fixedly connected is arranged on one side of the diversion elbow 3 close to the gate plate 2. When the filter mesh 9 needs to be removed for cleaning, the gate plate 2 is controlled to move downward to block the inside of the gate housing 1. At this time, the gate plate 2 will squeeze the second elastic box 5, as shown in FIG. Figure 3 As shown, the gas stored in the second elastic box 5 enters the first elastic box 4 fixedly connected to the other side of the guide elbow 3, so that the first elastic box 4 expands.

[0029] A disassembly passage 21 is provided at the top of the gate housing 1 , and a sealing block 11 fixedly connected to one side of the filter mesh 9 and the top of the filter mesh 9 both penetrate the disassembly passage 21 . The filter mesh 9 and the sealing block 11 block the disassembly passage 21 to ensure the sealing inside the gate housing 1 .

[0030] At this time, the pneumatic cylinder 18 and the hydraulic telescopic rod 13 are controlled to work successively. At this time, the pneumatic cylinder 18 fixedly connected to the top of the transmission plate 16 works to push the transmission cross plate 19 fixedly connected at one end, and one side of the square plate 17 slidably connected to the top of the transmission plate 16 is fixedly connected to the transmission cross plate 19, so the transmission cross plate 19 can drive the square plate 17 to move, so that one end of the square plate 17 is inserted into the inside of the clamping frame 20 fixedly connected to the top of the first fixed frame 14, and the other end of the square plate 17 completely leaves the inside of the clamping frame 20 of the track of the second fixed frame 15. Under the action of the first fixed frame 14, the clamping frame 20 fixed to the first fixed frame 14 and the square plate 17 , the transmission plate 16 drives the first fixed frame 14 to move up and down when it moves up and down, and the hydraulic telescopic rod 13 fixedly connected to the top of the gate housing 1 works after the pneumatic cylinder 18 has finished working. When the working hydraulic telescopic rod 13 pushes the transmission plate 16 fixedly connected to the top to move up, the transmission plate 16 drives the first fixed frame 14 to move up through the square plate 17, so that the filter mesh 9 fixedly connected to the first fixed frame 14 moves up and leaves the inside of the gate housing 1. Then the staff pulls the first fixed frame 14 to make the clamping frame 20 fixedly connected to the first fixed frame 14 leave the outside of the square plate 17, so that the filter mesh 9 can appear and be cleaned and dredged. After the filter mesh 9 is processed, the clamping frame 20 fixed to the first elastic box 4 is set on the outside of the square plate 17. At this time, the hydraulic telescopic rod 13 works to drive the filter mesh 9 to move down and reset, and the filter mesh 9 is installed inside the gate housing 1.

[0031] After the filter mesh 9 leaves the gate shell 1, the top of the telescopic tube 7 loses its obstruction, and the force required for the expansion of the telescopic tube 7 is less than the force required for the expansion of the first elastic box 4. Therefore, the internal gas of the first elastic box 4 enters the telescopic tube 7 through the guide elbow 3, causing the telescopic tube 7 to push the supporting top plate 8 fixedly connected to the top to move upward, and the supporting top plate 8 with one side heavier and the other side lighter will tilt. At this time, the telescopic tube 7 and the supporting top plate 8 cooperate to prevent impurities and garbage at the bottom of the inner cavity of the gate shell 1 from clogging the track of the filter mesh 9 moving downward and resetting, ensuring that the bottom of the filter mesh 9 can be smoothly inserted into the inner groove 6 opened at the bottom of the inner cavity of the gate shell 1, avoiding the situation where the filter mesh 9 cannot be tightly attached to the gate shell 1.

[0032] A second fixing frame 15 is fixedly connected to the top of the gate plate 2, and a clamping frame 20 is fixedly connected to the top of the second fixing frame 15. When the pneumatic cylinder 18 drives the square plate 17 to reset, one end of the square plate 17 is inserted into the clamping frame 20 of the track of the second fixing frame 15. At this time, the hydraulic telescopic rod 13 can work to drive the gate plate 2 to move upward.

[0033] In addition, under normal conditions, the pneumatic cylinder 18 is controlled to drive the square plate 17 to move a certain distance so that the two ends of the square plate 17 are located inside the two clamping frames 20. When the hydraulic telescopic rod 13 is not working, the tops of the first fixed frame 14 and the second fixed frame 15 are limited and cannot be displaced.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
