Description

Technical Field

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

[0002] Hydraulic gates play an important role in water conservancy projects. They can close the openings of structures as needed to regulate the water level and flow in the upstream and downstream areas, thereby achieving benefits such as flood control, irrigation, water supply, power generation, and navigation. At the same time, hydraulic gates can also be used to remove floating debris, silt, ice, etc., or provide necessary conditions for the maintenance of related structures and equipment.

[0003] For example, application number CN202020768143.8 relates to the field of water conservancy engineering technology, specifically a gate for water conservancy projects. This utility model includes a gate body, which comprises a main water-retaining plate and fixed plates disposed on both sides of the main water-retaining plate. Each of the two fixed plates has a first rotating frame at its top, and a drive shaft is rotatably connected between the two first rotating frames. By incorporating the drive shaft in the gate body, its counterclockwise rotation shortens the pull rope, which then pulls the main water-retaining plate upwards, thus eliminating the need for manual intervention. Second limiting blocks are installed, allowing water in the cavity to flow out between these blocks, thereby diverting the flow and reducing the impact force during water release. Several trapezoidal blocks are inserted into and engaged with the second limiting blocks, and locking blocks are engaged with locking slots, thus limiting and fixing the closed main water-retaining plate, improving its stability.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of the great pressure exerted on the gate during sluice gate opening and closing, making it very difficult to open or close manually, and the gate needing to resist underwater water pressure when closed, and the water flow exerting a great impact on the gate when releasing water, which can easily damage the gate, during use, because the valve cannot effectively intercept garbage and debris in the water when it is open, these substances will enter the valve port with the water flow and eventually flow into the downstream river channel, causing pollution or blockage problems.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting an L-shaped baffle plate and a through hole, allows garbage and debris to be intercepted by the L-shaped baffle plate when the gate is opened. Then, the water flows into the downstream river channel through the through hole. This solves the problem that when the valve is open, it cannot effectively intercept garbage and debris in the water. These substances will enter the valve port with the water flow and eventually flow into the downstream river channel, causing pollution or blockage. This utility model has the advantage of garbage cleaning.

[0015] 2. This utility model, through the setting of a cleaning mechanism, allows garbage to flow into the L-shaped baffle plate along with debris when the main baffle plate is open. Then, water flows out through the through holes, and the garbage is adsorbed into the through holes along with the water flow. At the same time, the scraper moves through the surface of the threaded screw to clean the garbage adsorbed in the through holes on the inner wall of the L-shaped baffle plate, preventing the garbage from clogging the through holes and preventing the water from flowing downstream. Furthermore, through the setting of a driving mechanism, the motor is started to drive the first bevel gear to rotate, and then the first bevel gear drives the second bevel gear to rotate through the meshing connection. Then, the second bevel gear drives the screw to rotate, thereby driving the scraper to move.

[0016] 3. By setting a second fixing block and a fixing rod, when the scraper moves on the surface of the lead screw through a threaded connection, the left side of the scraper is sleeved on the surface of the fixing rod and moves. Then, the second fixing block supports the fixing rod, and the fixing rod limits the movement of the scraper. Furthermore, by setting a linear bearing, the friction generated by the lead screw contact is reduced when the lead screw rotates inside the linear bearing, thus making the rotation of the lead screw smoother and more stable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] like Figures 1 to 3 As shown, the present invention provides a water conservancy gate for water conservancy projects, including a base 1, a fixing plate 2, a main water-retaining plate 3, trapezoidal blocks 4, limiting blocks 5, and a lifting device 6. The fixing plates 2 are fixedly connected to both sides of the top of the base 1. The trapezoidal blocks 4 are fixedly connected to the bottom of the front of the main water-retaining plate 3. Several trapezoidal blocks 4 are arranged in a rectangular and equidistant manner. The limiting blocks 5 are fixedly connected to the front side of the top of the base 1. Several limiting blocks 5 are arranged in a rectangular and equidistant manner. The two sides of the main water-retaining plate 3 are slidably connected to the inner side of the fixing plate 2. The lifting device 6 is fixedly connected to the front side of the top of the fixing plate 2. The lifting end of the lifting device 6 is fixedly connected to the front of the main water-retaining plate 3. An L-shaped blocking plate 7 is fixedly connected to the rear side of the inner side of the fixing plate 2. A through hole 8 is opened on the front of the L-shaped blocking plate 7. A cleaning mechanism 9 is arranged inside the L-shaped blocking plate 7. A driving mechanism 10 is arranged on the top of the L-shaped blocking plate 7.

[0023] refer to Figure 2 The cleaning mechanism 9 includes a scraper 91, a lead screw 92, and a first fixing block 93. The first fixing block 93 is fixedly connected to the bottom of the right side of the inner wall of the L-shaped baffle 7. The lead screw 92 is movably connected to the top of the first fixing block 93. The top end of the lead screw 92 is movably connected to the rear side of the right side of the top of the inner wall of the L-shaped baffle 7. The scraper 91 is threadedly connected to the left side of the surface of the lead screw 92.

[0024] As a technical optimization of this utility model, by setting up a cleaning mechanism 9, when the main baffle plate 3 is open, the garbage flows into the L-shaped baffle plate 7 along with the debris. Then the water flows out through the through hole 8, and the garbage will be adsorbed on the through hole 8 along with the water flow. At the same time, the scraper 91 moves on the surface of the threaded screw 92 to clean the garbage adsorbed on the through hole 8 of the inner wall of the L-shaped baffle plate 7, preventing the garbage from clogging the through hole 8 and causing the water to be unable to flow to the downstream river channel.

[0025] refer to Figure 3The drive mechanism 10 includes a motor 101, a first bevel gear 102 and a second bevel gear 103. The motor 101 is fixedly connected to the right side of the top of the L-shaped baffle 7. The first bevel gear 102 is fixedly connected to the output end of the motor 101. The second bevel gear 103 is meshed with the rear side of the first bevel gear 102. The bottom end of the second bevel gear 103 is fixedly connected to the top end of the lead screw 92.

[0026] As a technical optimization of this utility model, by setting a drive mechanism 10, starting the motor 101 to drive the first bevel gear 102 to rotate, then the first bevel gear 102 drives the second bevel gear 103 to rotate through meshing connection, and then the second bevel gear 103 drives the lead screw 92 to rotate, thereby causing the second bevel gear 103 to drive the scraper 91 to move.

[0027] refer to Figure 3 A second fixing block 11 is fixedly connected to the bottom of the left side of the inner wall of the L-shaped baffle 7. A fixing rod 12 is fixedly connected to the top of the second fixing block 11. The top of the fixing rod 12 is fixedly connected to the rear side of the top left side of the L-shaped baffle 7. The left side of the scraper 91 is sleeved on the top of the surface of the fixing rod 12.

[0028] As a technical optimization of this utility model, by setting a second fixing block 11 and a fixing rod 12, when the scraper 91 moves on the surface of the lead screw 92 through a threaded connection, the left side of the scraper 91 is sleeved on the surface of the fixing rod 12 and moves. Then the second fixing block 11 supports the fixing rod 12, and the fixing rod 12 limits the movement of the scraper 91.

[0029] refer to Figure 3 A linear bearing 13 is fixedly connected to the top of the first fixing block 93, and the bottom end of the lead screw 92 is sleeved inside the linear bearing 13.

[0030] As a technical optimization of this utility model, by setting a linear bearing 13, the friction generated by the contact of the lead screw 92 is reduced when the lead screw 92 rotates inside the linear bearing 13, thereby making the rotation of the lead screw 92 smoother and more stable.

[0031] refer to Figure 2 The bottom of the L-shaped baffle plate 7 is fixedly connected to a collection box 14. The bottom of the collection box 14 is fixedly connected to the rear side of the top of the base 1. A water outlet hole 15 is provided on the top of the collection box 14.

[0032] As a technical optimization of this utility model, by setting up a collection box 14 and a water outlet 15, when the scraper 91 pushes the garbage adsorbed on the inner wall of the L-shaped baffle 7 to the bottom, the water will flow smoothly through the water outlet 15 opened in the collection box 14, and at the same time the water will carry the garbage into the collection box 14, thereby collecting the garbage after cleaning the L-shaped baffle 7.

[0033] refer to Figure 2 The back of the collection box 14 is provided with a movable plate 16, and both sides of the back of the collection box 14 are provided with sliding grooves 17. The inside of the sliding grooves 17 is slidably connected to a limiting block 18, and the front of the limiting block 18 is movably connected to the back of the movable plate 16.

[0034] As a technical optimization of this utility model, by setting up a movable plate 16, a slide 17 and a limiting block 18, the limiting block 18 moves upward through the slide 17, and then the movable plate 16 rotates to open the collection box 14 to clean the garbage inside. After that, the limiting block 18 is moved to the bottom of the slide 17 to block the rotation of the movable plate 16, thereby completing the cleaning and closing of the collection box 14.

[0035] The working principle and usage process of this utility model are as follows: When the main baffle plate 3 is open, the garbage flows into the L-shaped baffle plate 7 along with the debris. Then, the water flows out through the through hole 8, and the garbage is adsorbed into the through hole 8 along with the water flow. The motor 101 is started to drive the first bevel gear 102 to rotate. Then, the first bevel gear 102 drives the second bevel gear 103 to rotate through meshing connection. Then, the second bevel gear 103 drives the lead screw 92 to rotate. After that, the lead screw 92 drives the scraper 91 to move through the threaded connection. At the same time, the scraper... The left side of scraper 91 is fitted onto the surface of fixed rod 12 and moves to limit the movement of scraper 91. This cleans the garbage adsorbed by the through hole 8 on the inner wall of L-shaped baffle 7, preventing the garbage from clogging the through hole 8 and preventing the water from flowing to the downstream river channel. This provides the advantage of garbage cleaning. At the same time, when scraper 91 pushes the garbage adsorbed by the inner wall of L-shaped baffle 7 to the bottom, the water will flow smoothly through the water outlet 15 opened in the collection box 14. The water will also carry the garbage into the collection box 14, thus collecting the garbage after cleaning L-shaped baffle 7.

[0036] In summary, this water conservancy project uses a sluice gate. By setting up an L-shaped baffle plate 7 and a through hole 8, when the gate is opened, the L-shaped baffle plate 7 intercepts garbage and debris, and then the water flows into the downstream river channel through the through hole 8. This solves the problem that when the valve is open, it cannot effectively intercept garbage and debris in the water, and these substances will enter the valve port with the water flow and eventually flow into the downstream river channel, causing pollution or blockage.
