Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and specifically relates to a water diversion sluice gate. Background Art

[0002] A patent with the patent announcement number CN219808336U3 proposes a water diversion sluice gate for water conservancy construction, which mainly includes a diversion sluice box, a water inlet pipe, a water outlet pipe, a pressure sensor and a buoyancy diversion component. It has the advantages of being driven by buoyancy without power. The set buoyancy diversion seat can float upward when the water level reaches, and then dock with the drainage docking port. At this time, the water inlet pipe is in a closed state. The sluice system controls the solenoid valve based on the pressure signal generated during docking, so that the water outlet pipe is unblocked, and the water in the sluice box is quickly diverted. Compared with the power-driven sluice gate, it has the advantages of non-powered design and convenient use.

[0003] However, during the use of the above patent, sediment is likely to accumulate inside the diversion sluice box due to the flow of the river and the operation of the water flow. The sediment will cause the water outlet pipe to be blocked, and thus frequent maintenance is required, reducing the reliability of the diversion sluice during use. Content of the Utility Model

[0004] Aiming at the above problems, the purpose of the present utility model is to provide a water diversion sluice gate to solve the problem that sediment is likely to accumulate inside the diversion sluice box due to the flow of the river and the operation of the water flow during use. The sediment will cause the water outlet pipe to be blocked, and thus frequent maintenance is required, reducing the reliability of the diversion sluice during use.

[0005] To achieve the above purpose, the technical solution adopted by the present utility model is: a water diversion sluice gate, including a diversion sluice box and a discharge rod. A water inlet pipe is installed at the top of the diversion sluice box, and a pressure sensor is installed inside the bottom of the water inlet pipe. An electromagnetic plug valve is installed in the middle of the water inlet pipe. A guide post is installed on the inner wall of the diversion sluice box, and a buoyancy diversion seat is sleeved on the guide post. A filter screen plate is installed at the bottom of the diversion sluice box, and a water outlet pipe is connected to the bottom of the diversion sluice box. A solenoid valve I is installed on the water outlet pipe. The discharge rod is installed at the bottom of the diversion sluice box, and a water filter net is snap-fitted inside the discharge rod. A drive motor is installed at the end of the discharge rod, and a spiral conveyor rod is connected to the output end of the drive motor. A connecting pipe is connected to the bottom of the discharge rod, and a solenoid valve II is installed at one end of the discharge rod away from the drive motor.

[0006] The beneficial effect of the present utility model is: during the diversion process, the filter screen plate makes the deposited sediment converge near the discharge rod. Open the drive motor and the solenoid valve II, and the drive motor drives the spiral conveyor rod to rotate to discharge the deposited sediment through the solenoid valve II. By using this method, it can effectively avoid blockage caused by sediment deposition during subsequent diversion.

[0007] To facilitate the filtration of sediment by the water filter screen:

[0008] As a further improvement to the above technical solution: The water filter screen and the discharge rod are arranged with their axes coinciding.

[0009] The beneficial effect of this improvement is that the coinciding axes can enable the water filter screen to better cooperate with the screw conveyor rod to filter sediment, thereby facilitating the rapid filtration of water by the water filter screen and then discharging it into the interior of the diversion sluice box through the connecting pipe.

[0010] As a further improvement to the above technical solution: A support convex block is installed at the connection between the water filter screen and the discharge rod, and the convex block adopts a strip structure.

[0011] The beneficial effect of this improvement is that the support convex block can support the water filter screen, and in this way, the efficiency and effect of the water filter screen cooperating with the screw conveyor rod to filter sediment can be effectively guaranteed.

[0012] To facilitate the discharge of sediment:

[0013] As a further improvement to the above technical solution: A discharge port is provided at one end of the discharge rod away from the drive motor.

[0014] The beneficial effect of this improvement is that the sediment inside the discharge rod can be conveniently discharged through the discharge port.

[0015] As a further improvement to the above technical solution: The discharge rod and the diversion sluice box are arranged parallel to each other.

[0016] The beneficial effect of this improvement is that the parallel arrangement can enable the sediment inside the discharge rod to be smoothly conveyed out of the interior of the discharge rod.

[0017] To ensure the connection between the discharge rod and the diversion sluice box:

[0018] As a further improvement to the above technical solution: Two connecting pipes are symmetrically arranged about the midline of the diversion sluice box, and a one-way valve is installed on the connecting pipe.

[0019] The beneficial effect of this improvement is that the two connecting pipes can enable the water inside the discharge rod to be quickly discharged into the interior of the diversion sluice box, and the one-way valve can prevent water from entering the interior of the discharge rod through the connecting pipe and affecting the filtration effect.

[0020] To facilitate the convergence of sediment:

[0021] As a further improvement to the above technical solution: The upper surface of the filter mesh plate is inclined.

[0022] The beneficial effects of this improvement are as follows: The inclined setting enables the sediment on the filter screen plate to quickly converge into the discharge rod, facilitating the subsequent discharge of sediment.

[0023] To ensure the sealing of the inlet pipe by the buoyancy shunt seat:

[0024] As a further improvement of the above technical solution: A guiding sealing rod is provided at the top of the buoyancy shunt seat.

[0025] The beneficial effects of this improvement are as follows: The guiding sealing rod can enable the buoyancy shunt seat to reliably seal the inlet pipe. Description of the Drawings

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0033] Such as Figures 1-5As shown in the figure, a flow-dividing sluice includes a flow-dividing sluice box 1 and a discharge rod 2. An inlet pipe 11 is installed at the top of the flow-dividing sluice box 1, and a pressure sensor 12 is installed on the inner side of the bottom of the inlet pipe 11. An electromagnetic plug valve 18 is installed in the middle of the inlet pipe 11. A guide post 13 is installed on the inner wall of the flow-dividing sluice box 1, and a buoyancy flow-dividing seat 14 is sleeved on the guide post 13. A filter screen plate 15 is installed at the bottom of the flow-dividing sluice box 1, and a water outlet pipe 16 is connected to the bottom of the flow-dividing sluice box 1. A solenoid valve 17 is installed on the water outlet pipe 16. The discharge rod 2 is installed at the bottom of the flow-dividing sluice box 1, and a water filter screen 21 is snap-fitted inside the discharge rod 2. A drive motor 22 is installed at the end of the discharge rod 2, and a spiral conveyor rod 23 is connected to the output end of the drive motor 22. A connecting pipe 24 is connected to the bottom of the discharge rod 2, and a solenoid valve 25 is installed at one end of the discharge rod 2 away from the drive motor 22. During the flow-dividing process, the filter screen plate 15 causes the deposited sediment to gather near the discharge rod 2. Open the drive motor 22 and the solenoid valve 25, and the drive motor 22 drives the spiral conveyor rod 23 to rotate to discharge the deposited sediment through the solenoid valve 25. Using this method can effectively avoid blockage caused by sediment deposition during subsequent flow division. The water filter screen 21 and the discharge rod 2 are arranged with their axes coinciding. The axis-coinciding arrangement can enable the water filter screen 21 to better cooperate with the spiral conveyor rod 23 to filter the sediment, and then facilitate the water to be quickly filtered by the water filter screen 21 and discharged into the flow-dividing sluice box 1 through the connecting pipe 24. A support convex block is installed at the connection between the water filter screen 21 and the discharge rod 2, and the convex block is in a strip structure. The water filter screen 21 can be supported by the support convex block. Using this method can effectively ensure the efficiency and effect of the water filter screen 21 cooperating with the spiral conveyor rod 23 to filter the sediment. A discharge port is arranged at one end of the discharge rod 2 away from the drive motor 22. The sediment inside the discharge rod 2 can be conveniently discharged through the discharge port. The discharge rod 2 and the flow-dividing sluice box 1 are arranged parallel to each other. The parallel arrangement can enable the sediment inside the discharge rod 2 to be smoothly transported out of the discharge rod 2. Two connecting pipes 24 are symmetrically arranged about the midline of the flow-dividing sluice box 1, and a one-way valve is installed on the connecting pipe 24. The two connecting pipes 24 can enable the water inside the discharge rod 2 to be quickly discharged into the flow-dividing sluice box 1, and the one-way valve can prevent water from entering the discharge rod 2 through the connecting pipe 24 and affecting the filtering effect. The upper surface of the filter screen plate 15 is inclined. The inclined setting can enable the sediment on the filter screen plate 15 to quickly converge into the discharge rod 2, facilitating the subsequent discharge of the sediment. A guide plugging rod is arranged at the top of the buoyancy flow-dividing seat 14. The guide plugging rod can enable the buoyancy flow-dividing seat 14 to reliably plug the inlet pipe 11.

[0034] The working principle of the utility model is as follows: when using the device, open the electromagnetic plug valve 18, and water flows into the inside of the shunt gate box 1 through the water inlet pipe 11. As the water enters, the guide post 13 rises under the action of buoyancy. The guide post 13 contacts the water inlet pipe 11 and the pressure sensor 12 to block the water inlet pipe 11. At this time, the pressure sensor 12 transmits a signal to the main console. After the main console closes the electromagnetic plug valve 18, it opens the first electromagnetic valve 17 to quickly discharge the shunted water. During the shunting process, driven by the water flow and in cooperation with the inclined filter screen plate 15, the deposited sediment can be gathered near the discharge rod 2. The water inside the deposited sediment will be filtered by the water filter net 21 and flow into the inside of the shunt gate box 1 through the connecting pipe 24. After discharging, open the drive motor 22 and the second electromagnetic valve 25. The drive motor 22 drives the spiral conveyor rod 23 to rotate to discharge the deposited sediment through the second electromagnetic valve 25. The remaining water in the sediment is extruded by the conveyor, filtered by the water filter net 21, and then flows back into the inside of the shunt gate box 1 through the connecting pipe 24. By adopting this method, it can effectively avoid blockage caused by sediment deposition during subsequent shunting.
