Description

Technical Field

[0001] This invention relates to the field of gate drainage technology, and in particular to a gate for river channels. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They can be used to intercept water flow, control water level, regulate flow, and discharge sediment and floating debris. Therefore, dams are built in rivers of all sizes, and gates are installed on the dams to artificially control the water in the river.

[0003] Based on the above, existing river gates have the following shortcomings:

[0004] 1. The gate is usually made of a relatively thick iron plate. Because there is no pressure relief hole in the gate, when the river water hits the gate, it will put a lot of pressure on the gate, causing the gate to deform and thus affecting the opening of the gate.

[0005] 2. The gate usually slides vertically in the sluice gate. Floating objects or silt in the river water will accumulate on the back side of the gate. Floating objects will get tangled at the connection between the gate and the sluice gate, thus affecting the opening of the gate. Summary of the Invention

[0006] In view of this, the present invention provides a river gate with a discharge port at the bottom end face of the overflow outlet for pre-pressure relief during water release, and a vortex is formed under the action of the guide hole to reduce the pressure caused by the opening of the floodgate.

[0007] This invention provides a river gate, specifically comprising: a water-blocking gate; the top of the water-blocking gate is provided with a winch, on which a cable and wire are wound, and the bottom of the cable and wire are connected to a sliding frame; characterized in that: a pull rod is connected to the front side of the sliding frame, a flood discharge gate is connected to the front end of the pull rod, an interception plate is inserted into the rear side of the flood discharge gate, a water-blocking block is provided in the front side wall of the flood discharge gate, a control screw is connected inside the water-blocking block, a drive rod is engaged at the top of the control screw, a drive motor is installed at the rear side of the middle of the drive rod, two U-shaped guide slides are symmetrically installed on the rear side wall of the water-blocking gate, and a guide frame is installed on the rear side wall of the water-blocking gate between the two guide slides.

[0008] Furthermore, two winches are symmetrically arranged on the top end face of the water-blocking gate, and a winch is rotatably connected between the two winches. A water outlet is opened through the bottom of the front and rear side walls of the water-blocking gate. An "L"-shaped guide frame is fixedly installed on the top of the left and right sides of the water-blocking gate behind the water outlet. An "L"-shaped guide groove is opened in the vertical side wall of the guide frame.

[0009] Further, the sliding frame is in a "mouth" shape and guiding rings are provided on the left and right outer side walls. Hinge joints are provided at both ends of the upper and lower side walls of the sliding frame, and tie rods are connected to the hinge joints. A cable and wire penetrates and is connected to the middle of the rear side wall of the sliding frame.

[0010] Further, connection heads are provided at the four corners of the rear side wall of the flood discharge gate and are connected to the front ends of the tie rods. Guide wheels are connected to the outside of the two connection heads at the top of the rear side wall of the flood discharge gate, and the guide wheels are slidably connected in the guiding chutes of the guiding frame. Three rectangular overflow ports are equidistantly arranged in the middle of the front and rear side walls of the flood discharge gate. Connection slots are provided on both the left and right sides of the rear side wall of the overflow port, and intercepting plates are inserted into the connection slots.

[0011] Further, two inverted frustum-shaped water discharge openings are symmetrically opened in the bottom end face of the overflow port of the flood discharge gate. Four inclined water guiding holes are opened at the rear side of the water discharge openings. Mechanical chambers are opened at the corresponding positions above the overflow ports. Driving rods penetrate and are connected to the front sides of the three mechanical chambers. Driving worms are equidistantly arranged on the driving rods. A bevel gear is provided in the middle of the driving rod. A driving motor is installed in the mechanical chamber in the middle of the flood discharge gate. The front end of the driving shaft of the driving motor is connected to a bevel gear, and the two bevel gears are meshed with each other.

[0012] Further, a "U"-shaped scraping groove is provided at the bottom of the rear side wall of the intercepting plate. Filter meshes are correspondingly arranged between the intercepting plate and the overflow port and the rear side of the water guiding hole of the flood discharge gate. Pulling holes are symmetrically opened at the top of the intercepting plate.

[0013] Further, the bottom of the control screw is rotatably connected to the bottom of the overflow port of the flood discharge gate, and the top of the control screw is rotatably connected to the mechanical chamber of the flood discharge gate. A transmission worm gear is provided at the top of the control screw and is meshed with the driving worm of the driving rod.

[0014] Further, the water blocking block is inserted into the water discharge opening of the flood discharge gate in a pagoda shape, and a connecting column is connected between the top end faces of the two water blocking blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The intercepting plate inserted into the connection slot at the rear side of the overflow port can intercept the floating objects mixed in the river water, prevent the floating objects from winding around the mechanical structure of the flood discharge gate, avoid affecting the opening of the flood discharge gate, and the U-shaped scraping groove at the bottom of the rear side of the intercepting plate collects the floating objects when the intercepting plate is pulled up, which is convenient for cleaning the accumulated floating objects in the river water and improving the river environment.

[0017] 2. The water discharge openings opened in the bottom end face of the overflow port are used for performing the pre-pressure relief operation when discharging water, and form a vortex under the action of the water guiding holes, reduce the pressure caused when the flood discharge gate is opened by the water flow, and avoid sediment staying in the water discharge openings.

[0018] 3. When the winch is rotated to pull the cable and wire for the winding operation, the cable and wire pull the sliding frame upward, and at the same time, the pull rod pulls the floodgate out of the outlet to facilitate rapid drainage. This increases drainage efficiency and also removes silt, preventing silt from accumulating at the bottom of the water gate. Attached Figure Description

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0033] Example 1: Please refer to Figures 1 to 8 As shown:

[0034] This invention provides a river gate, including a water-blocking gate 1; a winch 2 is rotatably connected to the top of the water-blocking gate 1, a cable and wire 5 are wound on the winch 2, a sliding frame 6 is connected to the bottom of the cable and wire 5, a pull rod 7 is connected to the front side of the sliding frame 6, a flood discharge gate 8 is connected to the front end of the pull rod 7, an interception plate 9 is inserted into the rear side of the flood discharge gate 8, a water-blocking block 10 is slidably connected to the front side wall of the flood discharge gate 8, a control screw 11 is threadedly connected to the water-blocking block 10, a drive rod 12 is engaged at the top of the control screw 11, a drive motor 13 is installed at the rear side of the middle of the drive rod 12, guide slide rods 3 are symmetrically installed on the rear side wall of the water-blocking gate 1, the guide slide rods 3 are U-shaped cylinders, and guide frames 4 are symmetrically installed on the rear side wall of the water-blocking gate 1 between the two guide slide rods 3.

[0035] Two winches 101 are symmetrically arranged on the top end face of the water-blocking gate 1. A winch 2 is rotatably connected between the two winches 101. A water outlet 102 is opened through the bottom of the front and rear side walls of the water-blocking gate 1. A guide frame 4 is fixedly installed on the top of the left and right side walls of the water-blocking gate 1 behind the water outlet 102. The guide frame 4 is L-shaped, and an L-shaped guide groove 401 is opened in the vertical side wall of the guide frame 4.

[0036] Among them, the floodgate 8 has three overflow ports 803 at equal intervals on the front and rear side walls. The overflow ports 803 are rectangular. The left and right sides of the rear side wall of the overflow port 803 are provided with connecting slots 804, and interception plates 9 are inserted into the connecting slots 804.

[0037] Among them, a scraping groove 901 is provided at the bottom of the rear side wall of the intercepting plate 9. The scraping groove 901 is in a "U" shape. Filter meshes are correspondingly provided at the rear sides of the intercepting plate 9, the overflow port 803 of the flood discharge gate 8, and the water guiding holes 806. Pulling holes 902 are symmetrically opened at the top of the intercepting plate 9.

[0038] With the above technical solution, the water blocking gate 1 is installed in the river channel to block the river channel. A water outlet 102 is opened in the water blocking gate 1 and a flood discharge gate 8 is provided so as to perform flood discharge operations through the flood discharge gate 8. The overflow port 803 opened in the flood discharge gate 8 is used for overflow operations. However, an intercepting plate 9 is inserted into the connecting slot 804 connected to the rear side of the overflow port 803 to intercept and collect floating objects in the river, prevent the floating objects from winding around the mechanical structure of the gate, and avoid affecting the opening of the gate. The pulling hole 902 at the top of the intercepting plate 9 can be taken out from the connecting slot 804 through a hook. When taking it out, the floating objects are collected through the U-shaped scraping groove 901 at the rear side of the intercepting plate 9, thereby reducing the floating objects in the river channel and improving the river environment.

[0039] Embodiment 2:

[0040] Based on a gate for a river channel provided in Embodiment 1, the device inserts an intercepting plate 9 at the rear side of the overflow port 803 of the flood discharge gate 8 to intercept floating objects in the river water, prevent the floating objects from winding around the mechanical structure of the gate, and avoid affecting the opening of the gate. The gate for a river channel further includes: the sliding frame 6 is in a "mouth" shape. Guide rings 601 are provided on the left and right outer side walls of the sliding frame 6. The guide rings 601 are slidably connected to the guide sliding rods 3. Hinge joints 602 are provided at both the top and bottom ends of the sliding frame 6. Tie rods 7 are connected to the hinge joints 602. A cable and wire 5 penetrates and is connected to the middle of the rear side wall of the sliding frame 6. The cable and wire 5 is electrically connected to the driving motor 13.

[0041] Among them, connecting heads 801 are provided at the four corners of the rear side wall of the flood discharge gate 8. The connecting heads 801 are connected to the front ends of the tie rods 7. Guide wheels 802 are connected to the outer side walls of the two connecting heads 801 at the top of the rear side wall of the flood discharge gate 8. The guide wheels 802 are slidably connected in the guide chutes 401 of the guide frame 4.

[0042] Using the above technical solution, the winding and unwinding of the cable and wire 5 is controlled by the rotation of the winch 2 on the winch frame 101. When the cable and wire 5 is wound up, the cable and wire 5 pulls the sliding frame 6 upward. The guide rings 601 on the left and right sides of the sliding frame 6 are on the guide slide rod 3. The hinge joint 602 at the front end of the sliding frame 6 is connected to the pull rod 7 and the connector 801 and pulls the floodgate 8 out of the outlet 102 for rapid drainage. Opening the floodgate 8 in this way can form a vortex, which can increase the drainage efficiency and discharge the silt at the same time, preventing the silt from accumulating at the bottom of the water-blocking gate 1.

[0043] Example 3:

[0044] Based on the river gate provided in Embodiment 1, this device uses an intercepting plate 9 inserted behind the overflow port 803 of the flood discharge gate 8 to intercept floating objects in the river water, preventing them from getting tangled in the gate's mechanical structure and affecting its opening. The river gate also includes two symmetrically arranged discharge ports 805 on the bottom end face of the overflow port 803 of the flood discharge gate 8. Each discharge port 805 is shaped like an inverted frustum, and four... An inclined water guide hole 806 is provided, and a mechanical chamber 807 is provided at the top of the overflow port 803 of the flood discharge gate 8. A drive rod 12 is connected through the front side of the three mechanical chambers 807. A drive worm gear 1201 is provided at equal intervals on the drive rod 12. A bevel gear 14 is provided in the middle of the drive rod 12. A drive motor 13 is installed in the mechanical chamber 807 in the middle of the flood discharge gate 8. The front end of the drive shaft of the drive motor 13 is connected to the bevel gear 14, and the two bevel gears 14 mesh with each other.

[0045] The bottom of the control screw 11 is rotatably connected to the bottom of the overflow port 803 of the flood discharge gate 8, and the top of the control screw 11 is rotatably connected to the mechanical compartment 807 of the flood discharge gate 8. A transmission worm gear 1101 is provided on the top of the control screw 11, and the front side of the transmission worm gear 1101 is meshed with the rear side of the drive worm gear 1201 of the drive rod 12.

[0046] Among them, the water-blocking block 10 is pagoda-shaped and is inserted into the discharge port 805 of the floodgate 8. A connecting column 1001 is connected between the top end faces of the two water-blocking blocks 10.

[0047] By adopting the above technical solution, a drain outlet 805 is opened in the bottom end face of each overflow outlet 803, and a left-right inclined guide hole 806 is opened in the rear side wall of the drain outlet 805 to form a vortex-shaped water flow. This reduces the impact force of the water flow on the floodgate 8 when releasing water, reduces the water pressure borne by the floodgate 8 when it is fully open, and prevents silt from remaining in the drain outlet 805, thereby increasing the sealing performance of the water-blocking block 10 and the drain outlet 805. The drive motor 13 in the mechanical chamber 807 drives the drive rod 12 to rotate through the meshing bevel gear 14. The drive rod 12 drives the control screw 11 to rotate through the meshing connection of the drive worm 1201 and the transmission worm wheel 1101, thereby controlling the position of the water-blocking block 10 in the drain outlet 805 and controlling the flow rate of the released water.

[0048] The specific usage and function of this embodiment are as follows: The drive motor 13 is started, and the drive motor 13 drives the drive rod 12 to rotate through the bevel gear 14 meshing with the drive end. The drive rod 12 drives the control screw 11 to rotate through the worm gear drive mechanism composed of the drive worm 1201 and the transmission worm wheel 1101. The control screw 11 controls the water blocking block 10 to rise and fall at the discharge port 805 by rotating, so that when water is discharged, water can be initially discharged through the cooperation of the guide hole 806 and the discharge port 805, thereby reducing the water pressure on the floodgate 8. Then, the cable and wire 5 are wound onto the winch 2, and then... The rope and wire 5 pull the sliding frame 6 upward. When the sliding frame 6 slides upward, the pull rod 7 pulls the floodgate 8 backward and upward, thereby pulling the floodgate 8 out of the outlet 102 for large-flow water release. When water is not needed and water overflows from the overflow port 803 of the floodgate 8, the interceptor plate 9 is inserted into the connecting slot 804 on the rear side of the overflow port 803 to intercept and collect floating objects in the river. The pull hole 902 on the top of the interceptor plate 9 can be removed from the connecting slot 804 through the hook. When removing it, the floating objects are collected by the U-shaped scraper groove 901 on the rear side of the interceptor plate 9.
