Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a self-cleaning debris blocking net device for gates. Background Technology

[0002] In water conservancy projects, farmland irrigation, and urban water system management, sluice gates are crucial water flow control facilities, and their stable operation is of paramount importance. Natural water bodies often carry various debris such as branches, aquatic plants, and domestic waste. If these debris directly impacts the sluice gates with the water flow, it may not only damage the gate structure but also easily cause channel blockage, affecting normal flood control or water regulation functions.

[0003] To address this issue, debris-blocking nets or screens are typically installed in front of the gate. These devices effectively prevent most debris from entering the gate, ensuring its safety and smooth water flow. However, this method also introduces a new problem: the intercepted debris accumulates and adheres to the surface of the net, clogging the mesh.

[0004] As debris accumulates on the barrier net, it severely affects the water flow area, reduces water flow efficiency, and creates a significant water level difference on both sides of the net. The resulting high water pressure can damage the net's structure. Therefore, regular cleaning of the barrier net is essential. Currently, most cleaning methods rely on manual dredging, which is not only labor-intensive and inefficient, but also poses extremely high safety risks during flood season or in severe weather conditions, making timely and effective cleaning impossible.

[0005] Therefore, this utility model proposes a self-cleaning debris blocking net device for gates to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a self-cleaning debris blocking net device for gates, aiming to improve the problem in the prior art where the cleaning components and the debris blocking net are prone to wear due to long-term friction, resulting in gaps between the two, which in turn leads to incomplete debris cleaning and a significant decrease in cleaning effect over time.

[0007] To achieve the above objectives, this utility model provides a self-cleaning debris blocking net device for gates, comprising: a gate frame and a gate, wherein the gate is slidably connected to the inner side wall of the gate frame;

[0008] The obstruction net is connected to one side of the gate by splicing blocks, and also includes a cleaning component disposed on one side of the obstruction net;

[0009] The cleaning assembly includes a moving bar, a fixed plate, a swinging component, a scraper, a first rotating shaft, a first telescopic component, a fixed rod, and a second rotating shaft. The fixed plate is fixedly connected to the moving bar. The swinging component is rotatably connected to the fixed plate via the first rotating shaft. The scraper is fixedly connected to the swinging component. The output end of the first telescopic component is connected to the fixed rod. The fixed rod is rotatably connected to the swinging component via the second rotating shaft.

[0010] It also includes an adjustment component for adjusting the distance between the cleaning component and the debris-blocking mesh.

[0011] As a further description of the above technical solution:

[0012] Preferably, the adjusting assembly includes a motor, a fixed bar, a rack, and a gear. The motor is mounted on the gate frame, the fixed bar is fixedly connected to the gate frame, the output shaft of the motor drives the gear to rotate, the gear meshes with the rack, and the rack is connected to the moving bar.

[0013] Preferably, the adjustment assembly further includes a second telescopic member and an extension bar. The fixed bar is connected to the movable bar through the second telescopic member. An extension bar is provided on one side of the movable bar, and the extension bar is slidably connected to a groove opened in the fixed bar.

[0014] Preferably, one end of the swing member is rotatably connected to the fixed plate via the first rotating shaft, and the fixed rod is rotatably connected to the swing member at a position different from its connection point with the first rotating shaft via the second rotating shaft.

[0015] Preferably, the working surface of the scraper is in contact with the surface of the debris-blocking mesh.

[0016] Preferably, the rack is fixedly connected to one side of the movable bar.

[0017] Preferably, the system also includes a lift, which is connected to the gate and is used to drive the gate to move up and down along the gate frame.

[0018] Preferably, the telescopic movement of the first telescopic member drives the fixed rod to reciprocate, thereby driving the swing member to swing around the first rotating axis.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting up a cleaning component, the first telescopic component drives the fixed rod to reciprocate, and the second rotating shaft causes the swing component to swing around the first rotating shaft, thereby driving the scraper to reciprocate to scrape the debris-blocking net. This solves the problems of the existing technology where the debris-blocking net is easily blocked by debris, requires frequent manual cleaning, and has high maintenance costs. It achieves the effects of automatic real-time cleaning, prevention of blockage, ensuring smooth water flow, and significantly reducing the frequency of manual maintenance.

[0021] 2. This utility model, by setting an adjustment component, utilizes a motor-driven gear and rack meshing transmission to drive the moving strip connected to the cleaning component to move horizontally as a whole. This solves the problem in the prior art where the scraper and the debris-blocking screen of the cleaning device develop gaps due to long-term wear or installation errors, resulting in reduced cleaning effect and incomplete debris removal. It achieves the effects of automatically adjusting the distance between the scraper and the debris-blocking screen, compensating for wear, ensuring that the scraper always effectively adheres to the screen surface, and guaranteeing long-term stable cleaning efficiency.

[0028] 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.

[0029] Reference Figure 1 - Figure 4 This utility model provides a self-cleaning debris blocking net device for gates, which aims to solve the problem that the existing debris blocking nets used for water conservancy gates are easily blocked by debris carried by the water flow, which not only affects the smooth flow of water, but also requires a lot of manpower for regular cleaning, and the cleaning effect will be significantly reduced after the cleaning device and the net are worn and gaps are generated due to long-term use.

[0030] Specifically, it includes a gate frame 1 and a gate 2. The gate 2 is installed on the inner wall of the gate frame 1 in a sliding connection. The gate 2 can move stably up and down within the gate frame 1 to regulate the water flow. On one side of the gate 2, a debris-blocking net 5 is connected by a splicing block 4. The debris-blocking net 5 is the core filter component used to intercept floating objects, aquatic plants or other impurities in the water flow.

[0031] It also includes a cleaning component 7 for automatically removing debris attached to the debris-blocking mesh 5 and an adjustment component 8 for ensuring the cleaning effect.

[0032] The cleaning component 7 is disposed on one side of the impurity-blocking mesh 5. The cleaning component 7 can cover and clean the entire or most surface of the impurity-blocking mesh 5. The cleaning component 7 includes a movable strip 6 serving as its main support and moving base. A fixed plate 703 is fixedly connected to the movable strip 6. A swinging member 702 is rotatably connected to the fixed plate 703. The rotatable connection between the swinging member 702 and the fixed plate 703 is achieved through a first rotating shaft 704. The first rotating shaft 704 provides a stable swing center for the swinging member 702. A tool for directly scraping away impurities is fixedly connected to the swinging member 702. The scraper 701 is made of wear-resistant hard rubber to ensure that it will not damage the debris blocking mesh 5 while effectively scraping away debris. The cleaning component 7 is powered by the first telescopic member 705, which can be an electric push rod or a hydraulic cylinder. The output end of the first telescopic member 705 is connected to the fixed rod 706, and the other end of the fixed rod 706 is rotatably connected to the swing member 702 through the second rotating shaft 707. The linear telescopic motion of the first telescopic member 705 can be efficiently converted into the reciprocating swing motion of the swing member 702 around the first rotating shaft 704.

[0033] The adjusting component 8 is used to adjust the lateral distance between the entire cleaning component 7 and the impurity screen 5, thereby compensating for the gap between the scraper 701 and the impurity screen 5 caused by wear, and ensuring the cleaning effect. The adjusting component 8 includes a motor 801 as a power source. The motor 801 is mounted on the gate frame 1 by a mounting bracket. A fixing bar 802, which serves as a guide rail and base, is also fixedly connected to the gate frame 1. A gear 805 is connected to the output shaft of the motor 801. The motor 801 drives the gear 805 to rotate. The gear 805 meshes with a rack 803. The rack 803 is connected to the moving bar 6 of the cleaning component 7. Through the transmission and engagement of the gear 805 and the rack 803, the rotational motion of the motor 801 is converted into the linear movement of the rack 803 and the entire cleaning component 7, thereby achieving precise adjustment of the cleaning gap.

[0034] To further improve the stability and accuracy of the adjustment component 8 during the adjustment process, the adjustment component 8 also includes a second telescopic member 804 and an extension bar 806. The fixed bar 802 is connected to the moving bar 6 through the second telescopic member 804. The second telescopic member 804 has a certain telescopic buffering capacity, which can absorb vibrations during the adjustment process. The extension bar 806 is set on one side of the moving bar 6 and is slidably connected to a specially opened groove inside the fixed bar 802, providing additional support and guidance for the moving bar 6 when it moves laterally, effectively preventing the moving bar 6 from deflecting or shifting, and ensuring the smoothness and accuracy of the adjustment action.

[0035] To make the motion mechanism of the cleaning component 7 more precise and reliable, one end of the swing member 702 is rotatably connected to the fixed plate 703 via the first rotating shaft 704, while the fixed rod 706 is rotatably connected to the swing member 702 at a position different from its connection with the first rotating shaft 704 via the second rotating shaft 707. Specifically, the first rotating shaft 704 is located at one end or the middle of the swing member 702 as a fixed fulcrum, while the second rotating shaft 707 is located at the other end of the swing member 702 or on a force-bearing arm. When the fixed rod 706 applies a reciprocating linear force, it can generate an effective torque on the swing member 702, thereby driving the swing member 702 to swing efficiently around the first rotating shaft 704.

[0036] To achieve the best cleaning effect, the working surface of the scraper 701 is in close contact with the surface of the debris-blocking mesh 5. The working surface of the scraper 701 is designed to be flat or slightly curved to perfectly match the surface contour of the debris-blocking mesh 5, ensuring that no dead corners are missed during the scraping process. The scraper 701 and the debris-blocking mesh 5 maintain a slight elastic contact pressure, which can remove stubborn deposits while avoiding excessive frictional resistance.

[0037] To ensure stable and reliable power transmission of the adjustment component 8, the rack 803 is fixedly connected to one side of the moving bar 6 by multiple bolts, ensuring the integrity between the rack 803 and the moving bar 6. This allows the power to be transmitted to the moving bar 6 without loss when the gear 805 drives the rack 803 to move, thus moving the entire cleaning component 7.

[0038] It also includes a lift 3, which is connected to the gate 2 and is used to drive the gate 2 to move up and down along the inner side wall guide rail of the gate frame 1, thereby realizing the control of the opening degree of the entire gate.

[0039] The telescopic movement of the first telescopic member 705 will drive the fixed rod 706 to reciprocate linearly, and then through the transmission of the second rotating shaft 707, drive the swing member 702 to reciprocate around the first rotating shaft 704, which serves as a fixed fulcrum, thereby transforming the simple linear drive source into a large-range arc surface cleaning action.

[0040] Working principle: First, a gate 2 slides on the inner wall of the gate frame 1. The gate 2 moves up and down through the elevator 3. One side is connected to the debris-blocking net 5 through the splicing block 4. The debris-blocking net 5 can effectively prevent the flow of debris. A cleaning component 7 is set on the moving bar 6 on one side of the debris-blocking net 5 to clean it and ensure the fluidity of the water flow through the debris-blocking net 5. An adjustment component 8 is set on one side of the gate frame 1 to adjust the distance between the cleaning component 7 and the debris-blocking net 5 to ensure the cleaning effect of the cleaning component 7.

[0041] When cleaning debris from the obstruction net 5 in real time, the first telescopic component 705 first extends and retracts, causing the top fixed rod 706 to move up and down. The inner wall of the fixed rod 706 is fixed with the second rotating shaft 707, which is connected to one side of the swing component 702. At the same time, the swing component 702 is fixed to the fixed plate 703 through the first rotating shaft 704, and the fixed plate 703 is connected to the moving bar 6. Then, the second rotating shaft 707 drives the swing component 702 to swing up and down. The swing of the swing component 702 drives the scraper 701 to clean debris from the outside of the obstruction net 5 in real time, ensuring the flow of water and ultimately ensuring smooth water flow and stable operation of the gate 2, reducing the frequency of manual cleaning and improving the operation and maintenance efficiency of water conservancy facilities.

[0042] When adjusting the distance between the barrier net 5 and the scraper 701, the motor 801 is first installed inside the gate frame 1 and rotates to drive the gear 805 to rotate inside the fixed bar 802. The rotation of the fixed bar 802 drives the rack 803 connected to one side of the moving bar 6 to move. When the rack 803 moves, the moving bar 6 moves accordingly. The movement of the moving bar 6 drives the cleaning component 7 to move, so that the scraper 701 is always in contact with the barrier net 5, ensuring the cleaning effect of the cleaning component 7. At the same time, the fixed bar 802 is connected to the moving bar 6 through the second telescopic member 804, and the extension bar 806 on one side of the moving bar 6 slides in the groove of the fixed bar 802, thus ensuring that the movement of the moving bar 6 does not cause displacement. Finally, the adaptive adjustment eliminates the gap between the barrier net and the cleaning component 7, avoids incomplete cleaning of debris, and ensures the transparency of the barrier net and long-term stable interception and cleaning efficiency.
