Description

Technical Field

[0001] The invention relates to the technical field of water conservancy gates, and in particular to an automatic lifting and cleaning water conservancy gate. Background Art

[0002] Hydraulic engineering gates are structures built on rivers and channels to control flow and regulate water levels. However, during the use of hydraulic engineering gates, impurities such as silt are easily attached to the water blocking surface. When the attachment is thick, it will affect the opening and closing of the gate. Therefore, the water blocking surface of hydraulic engineering gates needs to be cleaned regularly.

[0003] In the prior art, manually operated scrapers are generally used to clean attachments on water conservancy project gates, which has a low degree of automation, high labor costs, and low efficiency. Therefore, we propose an automatic lifting and cleaning system for water conservancy gates to solve the above problems. Summary of the invention

[0004] Based on the technical problems that the attachments on the gates of water conservancy projects are generally cleaned by manually operating scrapers in the background technology, which has a low degree of automation, high labor costs and low efficiency, the present invention proposes an automatic lifting and cleaning method for water conservancy gates.

[0005] The present invention provides an automatic lifting and cleaning water conservancy gate, comprising a concrete frame, a gate body being slidably connected to the inner wall of the concrete frame, and the water conservancy gate body further comprising:

[0008] A driving assembly, the driving assembly comprising: two first bevel gears, a first motor, a transmission shaft and two second bevel gears, the first bevel gears being fixedly mounted on the top end of the corresponding first screw rod, the first motor being fixedly mounted on the right side of the concrete frame, the output shaft of the first motor passing through the right side of the concrete frame and extending to the inside of the chamber, the output shaft of the first motor being fixedly mounted on the right end of the transmission shaft, the left end of the transmission shaft being rotatably connected to the left inner wall of the chamber, the two second bevel gears being fixedly sleeved on the transmission shaft, and the second bevel gears being meshed with the corresponding first bevel gears;

[0009] A cleaning assembly is arranged on the front side of the concrete frame, and the cleaning assembly cooperates with the front side of the gate body.

[0010] By means of the above structure, the transmission shaft can be driven to rotate by starting the first motor. When the transmission shaft rotates, the two second bevel gears can be driven to rotate. Then, through the meshing transmission between the second bevel gears and the first bevel gears, the two first screws can be driven to rotate. When the two first screws rotate, the threaded connection between the first screws and the threaded tube can drive the gate body to move upward or downward. At this time, the automatic switching operation of the gate body can be realized, and the operation is time-saving, labor-saving, efficient and practical.

[0011] Preferably, the cleaning assembly includes an upper mounting plate, a lower mounting plate, a second motor, a second screw, a movable plate, an adjusting box and a scraper. The upper mounting plate and the lower mounting plate are both fixedly mounted on the front side of the concrete frame. The second motor is fixedly mounted on the top of the upper mounting plate. The output shaft of the second motor passes through the upper mounting plate and is rotatably connected to the upper mounting plate. The output shaft of the second motor is fixedly mounted on the second screw. The bottom end of the second screw is rotatably connected to the top of the lower mounting plate. The movable plate is threadedly sleeved on the second screw. The movable plate is slidably connected to the front side of the concrete frame. The adjusting box is fixedly mounted on the rear side of the movable plate.

The rear end of the scraper cooperates with the front side of the gate body. An adjusting assembly is provided inside the adjusting box, and the adjusting assembly cooperates with the scraper.

[0012] Furthermore, by starting the second motor, the second screw can be driven to rotate. At this time, the threaded connection between the second screw and the movable plate can drive the movable plate to move up and down. When the movable plate moves upward or downward, it can drive the adjusting box and the scraper to move upward or downward. When the scraper moves downward, the gate body can be scraped and cleaned. In this way, there is no need for personnel to use tools for manual cleaning, which greatly improves the cleaning efficiency and effect of the gate body. The operation is convenient and fast, saves time and effort, has a high degree of automation, and is easy for personnel to use.

[0013] Preferably, tracks are fixedly mounted on the left inner wall and the right inner wall of the concrete frame, and the left and right sides of the gate body are slidably connected in the two tracks respectively.

[0014] Furthermore, by setting the track, the gate body can be stably slidably limited and slidably supported, thereby ensuring the stable opening and closing of the gate body.

[0015] Preferably, the left and right ends of the movable plate are fixedly mounted with slip rings, two sliding shafts are arranged on the front side of the concrete frame, the top ends of the two sliding shafts are fixedly mounted on the bottom of the upper mounting plate, the bottom ends of the two sliding shafts are fixedly mounted on the top of the lower mounting plate, and the slip ring sliding sleeves are arranged on the corresponding sliding shafts.

[0016] Furthermore, through the sliding limit cooperation between the slip ring and the sliding shaft, the movable plate can be stably slidably limited and slidably supported, thereby ensuring the stability of the lifting and lowering movement of the movable plate, the adjustment box and the scraper.

[0017] Preferably, the adjusting assembly includes a first rotating shaft, a worm, a worm wheel, a second rotating shaft, an eccentric wheel and a baffle. The first rotating shaft is rotatably connected to the top of the adjusting box, the worm is fixedly mounted on the first rotating shaft, the worm is meshed with the worm wheel, the top end of the second rotating shaft is fixedly mounted on the bottom of the worm wheel, the bottom end of the second rotating shaft passes through the top of the adjusting box and extends to the interior of the adjusting box, the bottom end of the second rotating shaft is fixedly mounted on the top of the eccentric wheel, the bottom end of the baffle is fixedly mounted on the top of the scraper, the eccentric wheel contacts the front side of the baffle, and the scraper is elastically connected to the front inner wall of the adjusting box.

[0018] Furthermore, by rotating the first shaft, the worm can be driven to rotate, and the meshing transmission between the worm and the worm wheel can drive the second shaft to rotate. When the second shaft rotates, the eccentric wheel can be driven to rotate. When the eccentric wheel rotates, the baffle can be squeezed to move backward. When the baffle moves backward, the scraper can be driven to move backward. At this time, the distance between the scraper and the gate body can be adjusted. After the scraper is worn out due to long-term use, the distance between the scraper and the gate body can be adjusted to make the scraper and the gate body in stable contact, thereby ensuring the cleaning effect of the scraper on the gate body.

At this time, the automatic opening and closing operation of the gate body can be realized, and the operation is time-saving and labor-saving, with high efficiency and strong practicality.

[0027] 2. By starting the second motor, the second screw can be driven to rotate. At this time, the threaded connection between the second screw and the movable plate can drive the movable plate to move up and down. When the movable plate moves up or down, it can drive the adjustment box and the scraper to move up or down. When the scraper moves down, the gate body can be scraped and cleaned. In this way, there is no need for personnel to use tools for manual cleaning, which greatly improves the cleaning efficiency and effect of the gate body. The operation is convenient and fast, saving time and effort, with a high degree of automation, and easy for personnel to use;

[0028] 3. The worm can be driven to rotate by rotating the first rotating shaft.
