Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a lifting water conservancy engineering gate for water conservancy projects. Background Technology

[0002] The field of water conservancy engineering technology refers to the technical system involving a series of activities such as the development, utilization, control, allocation and protection of water resources. It covers multiple aspects of water conservancy projects, from planning and design to construction, operation and management and maintenance.

[0003] In water conservancy projects, gates are a crucial and widely used control device, mainly used to intercept water flow, control water level, or regulate flow. Lift gates, as one of the main types, open or close the orifice by vertically raising or lowering the gate leaf. Due to their simple structure, reliable operation, and convenient maintenance, they are widely used in small and medium-sized water conservancy projects, river management, and irrigation canal systems.

[0004] However, the applicant believes that the shortcomings are: when the equipment is in use, it is inconvenient to collect and process the garbage inside the water flow. Over time, this may lead to blockages or obstruction of water flow near the gate, and may also cause water pollution, thereby reducing the efficiency and practicality of the equipment.

[0005] Therefore, we propose a lifting-type hydraulic engineering gate for water conservancy projects to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a lifting gate for water conservancy projects to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lifting gate for water conservancy projects, comprising a gate body, The gate body has a storage slot inside, and a starting block is installed above both ends of the storage slot. A first motor is installed at the upper end of the gate body, and a lead screw is fixed to the output end of the first motor. A closing plate is spirally connected to the surface of the lead screw. Filter plates are fixed at both ends of the bottom of the gate body. An operating frame is fixed at one end of the gate body, and a second motor is installed on one side of the upper end of the operating frame. A rotating rod is fixed to the output end of the second motor, and traction ropes are fixed to both ends of the rotating rod. A protective post is fixed to the other end of the traction rope, and a collection plate is fixed to the lower end of the protective post. Adjusting blocks are engaged and slidably mounted on both sides of one end of the inner wall of the operating frame, and a sliding plate is fixed to one side of the bottom end of the adjusting block. A limit block is provided at the upper end of the closing plate, and an operating plate is fixed to the other end of the limit block.

[0008] Preferably, the surface of the closing plate is in contact with the surface of the storage groove, and the two sides of the closing plate are in contact with the starting block. When the closing plate moves upward so that its side presses against the starting block, the second motor can be started.

[0009] Preferably, a backstop plate is hinged to one end of the bottom of the operating frame, and multiple sets of diversion blocks are provided inside the backstop plate. Diversion plates are fixed at both ends of the bottom of the operating frame. When the closing plate enters the upper part of the gate body, the water flow can be diverted to the lower part of the gate body by the cooperation of multiple sets of diversion blocks. When the water flow is large, the backstop plate can be driven to rotate clockwise toward the inner wall of the operating frame.

[0010] Preferably, the rotating rod bearing rotates on the upper end of the inner wall of the operating frame, and limit plates are fixed at both ends of the rotating rod near the inner wall of the operating frame. The limit plates are in contact with the surface of the traction rope. By using the limit plates, displacement and breakage of the traction rope when it is entangled can be avoided.

[0011] Preferably, the sides of the collecting plate are all sloping, and the sides of the collecting plate are in contact with the inner wall of the operating frame. With the help of the slope, the garbage can be driven into the interior of the collection box more quickly.

[0012] Preferably, one end of the adjusting block is fixed with a T-shaped block, and the T-shaped block slides and engages inside the operating frame. One bottom end of the slide plate is inclined, and both ends of the operating frame are fixed with collection boxes. One end of the collection box is provided with an inlet. The lower surface of the inlet is in contact with the lower surface of the slide plate. Through the cooperation of the T-shaped block, the adjusting block can be more stable when moving. Through the shape of the slide plate, the garbage on the upper part of the collection plate can be moved more accurately.

[0013] Preferably, the two ends of the operating plate are respectively attached to the inner walls of the gate body and the operating frame. The lower end of the operating plate is triangular in shape, and the two sides of the lower end of the operating plate are attached to the corresponding surfaces of the two sets of adjusting blocks. When the operating plate moves downward, it can drive the two sets of adjusting blocks to move outward synchronously, and synchronously drive the sliding plate to displace the garbage on the upper part of the collection plate.

[0014] This utility model provides a lifting-type hydraulic engineering gate for water conservancy projects, which has the following beneficial effects: By starting the second motor to drive the rotating rod to rotate, the traction ropes wrapped around both ends of the rotating rod can extend downwards. This causes the protective column to move the collection plate downwards. When the bottom surface of the collection plate is in contact with the ground, the garbage flowing in after the gate is opened can be collected, preventing garbage from accumulating on the surface of the filter plate and causing slow water flow or blockage, thereby improving the efficiency of the equipment.

[0015] The first motor is started to drive the closing plate downward to close the gate. When the closing plate moves downward, the side of the closing plate can be separated from the starting block, thereby starting the second motor to drive the rotating rod to move in the opposite direction, so that the collecting plate moves upward until the upper surface of the collecting plate is in contact with the lower surface of the sliding plate. When the closing plate moves downward, it drives the operating plate downward, so that the two sets of adjusting blocks drive the two sets of sliding plates to move outward synchronously, thereby moving the garbage into the inside of the collection box for collection. Through the above operation, the long-term retention of garbage in the water and the resulting pollution can be avoided, thereby improving the practicality of the equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment proposes a lifting gate for water conservancy projects.

[0021] Example

[0022] like Figures 1 to 5 As shown in the figure, this embodiment proposes a lifting gate for water conservancy projects, including a gate body 1. The gate body 1 has a storage slot 2 inside, and a starting block 3 is installed above both ends of the storage slot 2. A first motor 4 is installed at the upper end of the gate body 1, and a lead screw 5 is fixed to the output end of the first motor 4. A closing plate 6 is spirally connected to the surface of the lead screw 5. Filter plates 7 are fixed at both ends of the bottom of the gate body 1. An operating frame 8 is fixed at one end of the gate body 1, and a second motor 11 is installed on one side of the upper end of the operating frame 8. A rotating rod 12 is fixed to the output end of the second motor 11, and traction ropes 13 are fixed to both ends of the rotating rod 12. A protective post 14 is fixed to the other end of the traction rope 13, and a collection plate 15 is fixed to the lower end of the protective post 14. The surface of the closing plate 6 is in contact with the surface of the storage slot 2, and both sides of the closing plate 6 are in contact with the starting block 3. The bottom end of the operating frame 8 is... The hinged rotation has a backstop plate 9, and the backstop plate 9 has multiple sets of diversion blocks inside. Both ends of the bottom of the operating frame 8 are fixed with diversion plates 10. The rotating rod 12 is rotatably rotated on the upper end of the inner wall of the operating frame 8. The two ends of the rotating rod 12 are fixed with limit plates 16 near the inner wall of the operating frame 8, and the limit plates 16 are in contact with the surface of the traction rope 13. The sides of the collecting plate 15 are all sloped, and the sides of the collecting plate 15 are in contact with the inner wall of the operating frame 8. The starting block 3 is connected to the second motor 11 for power supply. When the starting block 3 is pressed, the second motor 11 can be started to drive the rotating rod 12 to rotate clockwise. When the starting block 3 is released, the rotating rod 12 can be driven to rotate counterclockwise. When the starting block 3 is pressed for the first time, the second motor 11 can be turned on for a long time. When the equipment is not used for a long time, the second motor 11 will automatically turn off.

[0023] The storage slot 2 and the second motor 11 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] In the above embodiment, starting the first motor 4 can drive the lead screw 5 to rotate, thereby causing the closing plate 6 to move up or down inside the collection trough 2. When the closing plate 6 moves upward, the starting block 3 can be pressed to start the second motor 11, causing the rotating rod 12 to drive the traction rope 13 to extend downward, so that the collection plate 15 moves to the bottom of the equipment, thereby collecting the garbage. Through the cooperation of the two sets of filter plates 7, the garbage can be isolated to prevent garbage from entering the water gate and causing inconvenience to subsequent operations. When the closing plate 6 moves downward, it can detach from the surface of the starting block 3. At this time, the rotating rod 12 rotates in the opposite direction, causing the traction rope 13 to wrap around the surface of the rotating rod 12, thereby driving the collection plate 15 to move upward. Through the cooperation of the limiting plate 16, the position of the traction rope 13 is isolated to prevent the traction rope 13 from becoming loose.

[0025] Example

[0026] like Figure 6 As shown, based on the same concept as the above embodiment, this embodiment also proposes: Adjusting blocks 18 are slidably engaged on both sides of one end of the inner wall of the operating frame 8, and a sliding plate 19 is fixed to one side of the bottom end of the adjusting block 18; a limiting block is provided at the upper end of the closing plate 6, and an operating plate 20 is fixed to the other end of the limiting block; a T-shaped block is fixed to one end of the adjusting block 18, and the T-shaped block is slidably engaged inside the operating frame 8; one bottom end of the sliding plate 19 is inclined; and material collection boxes 17 are fixed to both ends of the operating frame 8, with an inlet at one end of the material collection box 17, the lower surface of which is flush with the sliding plate 19. The lower surfaces are in contact with each other. The two ends of the operating plate 20 are in contact with the inner walls of the gate body 1 and the operating frame 8, respectively. The lower end of the operating plate 20 is triangular. The two sides of the lower end of the operating plate 20 are in contact with the corresponding surfaces of the two sets of adjusting blocks 18. The two sides of the operating plate 20 are fixed with locking blocks. The lower end of the collection box 17 is provided with a discharge gate. The collection box 17 and the discharge gate are connected by threads. The upper ends of the operating frame 8 are provided with square grooves. The surface of the square grooves is in contact with the surface of one end of the adjusting block 18. The inclined surface of the adjusting block 18 is provided with a groove. The surface of the groove is in contact with the surface of the locking block.

[0027] In the above embodiment, when the closing plate 6 moves downward, it can simultaneously drive the operating plate 20 to move downward. At this time, the two sides of the operating plate 20 are pressed downward, driving the two sets of adjusting blocks 18 to move outward, and simultaneously driving the two sets of sliding plates 19 to move outward. Thus, the garbage collected on the surface of the collecting plate 15 can be moved to the inside of the collection box 17. When the garbage inside the collection box 17 is collected to a certain amount, the staff can open the discharge door to remove the garbage. The T-shaped block at one end of the adjusting block 18 can make the adjusting block 18 more stable when it moves. With the cooperation of the locking blocks on both sides of the operating plate 20, when the operating plate 20 moves downward, it can drive the two sets of adjusting blocks 18 to move outward, and when the operating plate 20 moves upward, it can drive the two sets of adjusting blocks 18 to move inward.

[0028] Working principle: When the equipment is in use, the first motor 4 is started to drive the lead screw 5 to rotate, which causes the closing plate 6 to move upward. At this time, the side of the closing plate 6 presses the starting block 3, thereby starting the second motor 11 to drive the rotating rod 12 to rotate clockwise. At this time, the traction rope 13 extends downward, causing the collection plate 15 to move to the bottom of the equipment, thereby collecting the garbage. At this time, according to the upward movement of the closing plate 6, the water flow is driven to flow. The water flow can drive the check plate 9 to rotate inward, thereby causing the garbage inside the water flow to accumulate on the upper surface of the collection plate 15. After the water flow is complete, the first motor 4 is started. At this time, the lead screw 5 rotates in the opposite direction, driving the closing plate 6 to move downward. At this time, the side of the closing plate 6 is separated from the surface of the starting block 3. The second motor 11 is started, driving the rotating rod 12 to rotate counterclockwise. At this time, the traction rope 13 is wrapped around the surface of the rotating rod 12, and drives the collecting plate 15 to move upward. When the traction rope 13 is fully wrapped, the upper surface of the collecting plate 15 is in contact with the lower surface of the sliding plate 19. As the closing plate 6 moves downward, it can drive the operating plate 20 to move downward, so that the two sets of adjusting blocks 18 drive the two sets of sliding plates 19 to move outward synchronously. The garbage collected on the upper end of the collecting plate 15 can be moved into the inside of the collection box 17. The above is the complete working principle of this utility model.
