Description

Technical Field

[0001] This utility model relates to the field of river dam technology, and in particular to a river dam for water conservancy projects. Background Technology

[0002] In today's water conservancy engineering system, river dams, as a key facility, are widely used in major river basins. They shoulder many important missions, including regulating river levels, controlling water flow, ensuring flood control and irrigation, and facilitating hydropower development. They play a core supporting role in maintaining the rational allocation and utilization of regional water resources. The stability and reliability of their operation directly affect the overall effectiveness of water conservancy projects and the balance of the surrounding ecological environment.

[0003] Traditional river dams in water conservancy projects, from a mechanical structure perspective, mainly consist of a base to support the weight of the entire dam structure and withstand the impact of water flow; a gate, serving as a crucial barrier to block or allow water flow; and a matching hoist, which, through mechanical transmission principles, uses gears, chains, screws, and other components to transmit power to the gate, achieving precise control of its opening and closing. At the technical level, based on changes in river water level, upstream and downstream water demand, and seasonal flood control requirements, operators use the hoist to move the gate up and down along predetermined guide rails, thereby effectively regulating the river flow.

[0004] Traditional river dams used in water conservancy projects lack effective pre-interception mechanisms. A large amount of garbage and debris generated by human activities in the river basin is carried directly towards the dam by the water flow. Once this garbage accumulates near the dam, it will interfere with the normal opening and closing of the dam, increase the workload of the hoisting machine, and affect the service life of the river dam. To address these problems, a new type of river dam for water conservancy projects is proposed to improve the dam structure. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a river-blocking gate for water conservancy projects, aiming to improve the problem that the lack of an effective pre-interception mechanism in the existing technology leads to a large amount of garbage and debris being directly rushed towards the gate with the water flow, interfering with the normal opening and closing of the gate and affecting the service life of the river-blocking gate. The above structure improves the gate's performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A river-blocking gate for water conservancy projects includes a base, an opening and closing device fixedly connected to the upper surface of the base, a screw threadedly connected inside the opening and closing device, a gate fixedly connected to one end of the screw, a gate sidewall slidably connected inside the base, a filter assembly and a cleaning assembly provided on the sidewall of the base.

[0008] The filter assembly includes a mounting base, the sidewall of which is fixedly connected to the sidewall of the base. A filter screen is slidably connected inside the mounting base. A rotating block is rotatably connected to the upper surface of the filter screen. A pull rope is rotatably connected to the lower surface of the rotating block. A fixing ring is slidably connected inside the filter screen. A connecting block is rotatably connected to the upper surface of the fixing ring. One end of the pull rope is rotatably connected to the sidewall of the connecting block. A locking block is fixedly connected to the sidewall of the fixing ring. A slider is fixedly connected to the sidewall of the fixing ring. A fixing seat is fixedly connected inside the filter screen. A spring is provided inside the filter screen.

[0009] As a further description of the above technical solution:

[0010] The cleaning assembly includes a fixing plate, the side wall of which is slidably connected to the inside of the base, a brush fixedly connected to the side wall of the fixing plate, and a scraper fixedly connected to the side wall of the fixing plate.

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

[0012] The side wall of the card block is slidably connected to the inside of the filter screen, the side wall of the card block is slidably connected to the inside of the mounting base, and the side wall of the slider is slidably connected to the inside of the filter screen.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the side wall of the fixed base, and the other end of the spring is fixedly connected to the side wall of the fixed ring.

[0015] As a further description of the above technical solution:

[0016] A mounting shell is fixedly connected to the side wall of the base, and a motor is fixedly connected to the side wall of the mounting shell.

[0017] As a further description of the above technical solution:

[0018] A rotating plate is fixedly connected to the output end of the motor, and a rotating sleeve is rotatably connected to the side wall of the base.

[0019] As a further description of the above technical solution:

[0020] A sliding block is rotatably connected to the side wall of the rotating plate, and one side wall of the sliding block is slidably connected inside the rotating sleeve.

[0021] As a further description of the above technical solution:

[0022] One end of the fixed plate is fixedly connected to a sliding block two, and the side wall of the sliding block two is slidably connected inside the rotating sleeve.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by installing a filter screen on the side wall of the base, garbage and debris can be blocked from entering the gate. By rotating the rotating block, the pull rope pulls the connecting block to compress the spring, thereby causing the locking block to disengage from the mounting seat. At this time, the filter screen can be pulled out to achieve the effect of replacing the filter screen. This solves the problem that some water conservancy projects lack an effective pre-interception mechanism for river dams. A large amount of garbage and debris generated by human activities in the river basin is carried directly towards the gate by the water flow. Once this garbage accumulates near the gate, it will interfere with the normal opening and closing of the gate, increase the workload of the hoist, and affect the service life of the river dam. The above structure improves the service life of the gate.

[0025] 2. In this utility model, the rotating plate is driven to rotate by starting the motor, which causes the sliding block one to slide inside the rotating sleeve and drive the rotating sleeve to start rotating, thereby pushing the sliding block two to slide, which in turn pushes the fixed plate to slide up and down, cleaning the side wall of the rising gate. This achieves the goal of eliminating the need for manual cleaning, reducing labor intensity and improving work efficiency. Attached Figure Description

[0033] 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.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a river-blocking gate for water conservancy projects, including a base 1, which provides a solid guarantee for the stable operation of the river-blocking gate. A gate opener 2 is fixedly connected to its upper surface. The gate opener 2 is a key power component controlling the opening and closing of the gate 4. Internally, it works in conjunction with a screw 3 via a threaded connection. One end of the screw 3 is fixedly connected to the gate 4, and the sidewall of the gate 4 is slidably connected inside the base 1. This tight and smooth sliding connection ensures the stability of the gate 4 during lifting and lowering. The sidewall of the base 1 is equipped with a filter assembly and a cleaning assembly to address common impurities and garbage problems in rivers, improving the overall performance and service life of the river-blocking gate. The filter assembly includes a mounting base 5, whose sidewalls are securely fixed to the sidewalls of the base 1, providing a stable platform for the subsequent installation and operation of the filter screen 6. The filter screen 6 is slidably connected inside the mounting base 5, effectively blocking various floating debris such as branches, plastic bottles, and packaging bags from entering the gate area 4. A rotating block 7 is rotatably connected to the upper surface of the filter screen 6, serving as an operating component for manual operation when the filter screen 6 needs to be replaced. A pull rope 8 is rotatably connected to the lower surface of the rotating block 7, and a fixing ring 10 is slidably connected inside the filter screen 6, acting as a central hub for connection and force transmission within the filter screen 6. A connecting block 9 is rotatably connected to the upper surface of the fixing ring 10, with one end of the pull rope 8 rotatably connected to the sidewall of the connecting block 9. A locking block 11 is fixedly connected to the sidewall of the fixing ring 10, engaging with the sliding connection structures inside the mounting base 5 and the filter screen 6. A slider 12 is fixedly connected to the sidewall of the fixing ring 10, slidably connected to the sidewall of the slider 12 inside the filter screen 6, enhancing the stability of the entire structure. A fixing seat 14 is fixedly connected inside the filter screen 6, providing a fixed attachment point for the spring 13. A spring 13 is installed inside the filter screen 6, with one end fixedly connected to the side wall of the fixing seat 14 and the other end fixedly connected to the side wall of the fixing ring 10.

[0035] In the actual operation of water conservancy projects, the opening and closing device 2, fixedly connected to the upper surface of the base 1, precisely converts rotational motion into linear motion, which then powerfully drives the screw 3 to slide downwards along a predetermined path. One end of the screw 3 is firmly connected to the gate 4. As the screw 3 descends, the gate 4 can be precisely positioned, forming a solid barrier against the river water and achieving precise control of the river's water level and flow. Meanwhile, rivers often contain a large amount of garbage and debris. If this is not effectively intercepted, it will bring many hidden dangers to the subsequent operation of the dam. The filter screen 6 installed on the side wall of the base 1 can efficiently intercept various floating garbage such as branches, plastic bottles, and packaging bags, preventing these debris from accumulating near the gate 4 at the source. Over time and with the accumulation of intercepted garbage, the filter screen 6 itself also needs regular maintenance and replacement. When this is needed, firstly, by rotating the rotating block 7, which is rotatably connected to the upper surface of the filter screen 6, the pull rope 8, which is closely connected to it, will rotate. The pull rope 8 transmits the rotational force of the rotating block 7 over a long distance. Pulling steadily at one end of the rope, which is rotatably connected to the side wall of the connecting block 9, smoothly transmits the tension of the pull rope 8 to the fixing ring 10. The fixing ring 10 is fixedly connected to the locking block 11 on its side wall and acts as a hub for connecting and transmitting force inside the filter screen 6. At this time, under the action of the pulling force, the fixing ring 10 begins to slide towards the center of the filter screen 6. This sliding process directly compresses the spring 13, which is fixed inside the filter screen 6, with one end connected to the side wall of the fixing seat 14 and the other end connected to the side wall of the fixing ring 10. Under normal conditions, the spring 13, due to its elastic extension characteristics, provides an outward pushing force to the fixing ring 10, causing the locking block 11 to be tightly and firmly locked into the mounting seat 5, thus firmly fixing the filter screen 6 to the mounting seat 5, unaffected by the impact and vibration of the water flow. However, when the spring 13 is compressed and contracts, the locking block 11 gradually disengages from the mounting seat 5, releasing the fixing effect on the filter screen 6. At this point, the operator only needs to gently pull the filter screen 6 upwards to remove it smoothly, and then perform cleaning, maintenance or replacement operations to ensure that the entire filter assembly can continue to play a role efficiently, and safeguard the smooth operation of the dam.

[0036] Reference Figure 1 and Figure 4The cleaning assembly includes a fixed plate 17, whose sidewall is slidably connected to the inside of the base 1. This sliding connection allows the fixed plate 17 to move smoothly along the sidewall of the base 1. A brush 18 and a scraper 19 are fixedly connected to the sidewall of the fixed plate 17. The scraper 19 has a certain rigidity and sharpness. A mounting shell 15 is fixedly connected to the sidewall of the base 1. The mounting shell 15 provides a protective mounting space for the motor 16. The motor 16 is fixedly connected to the sidewall of the mounting shell 15. The motor 16 is the power source for driving the cleaning assembly. A rotating plate 21 is fixedly connected to the output end of the motor 16. The rotating plate 21 makes a circular motion under the drive of the motor 16. A sliding block 22 is rotatably connected to its sidewall. The sidewall of the sliding block 22 is slidably connected to the inside of the rotating sleeve 20. This structural design allows the circular motion of the rotating plate 21 to be converted into the linear reciprocating motion of the sliding block 22 within the rotating sleeve 20. A rotating sleeve 20 is rotatably connected to the side wall of the base 1, and a sliding block 23 is fixedly connected to one end of the fixed plate 17. The side wall of the sliding block 23 is slidably connected inside the rotating sleeve 20, and works in conjunction with the sliding block 22 to ensure the stability of the fixed plate 17 during movement, prevent it from tilting or getting stuck, and ensure the smooth progress of the cleaning work.

[0037] When cleaning the gate 4 is required, it must first be adjusted to a suitable cleaning position. This step requires the use of the gate opener 2, which is fixedly connected to the upper surface of the base 1. The operator issues a command to activate the gate opener 2, converting the rotational motion into linear motion, driving the screw 3 to slide upwards along a predetermined path. The gate 4 is smoothly lifted up along the slide rail inside the base 1. Once the gate 4 is in place, the cleaning work officially begins. At this time, the operator starts the motor 16, and the output shaft of the motor 16 begins to rotate at high speed, driving the rotating plate 21, which is rigidly connected to it, to rotate synchronously. The side wall of the rotating plate 21 is rotatably connected to the sliding block 22, and the side wall of the sliding block 22 is tightly slidably connected inside the rotating sleeve 20. The rotational motion of the rotating plate 21 is cleverly converted into the reciprocating linear motion of the sliding block 22 within the rotating sleeve 20 through this structural design. Meanwhile, the rotating sleeve 20, as a crucial link in the entire power transmission chain, provides stable support for subsequent power transmission through its reliable rotational connection with the side wall of the base 1. Furthermore, it serves as a precise sliding track for sliding blocks 22 and 23, guiding them to move linearly along a predetermined trajectory. As the internal power of the rotating sleeve 20 changes due to the movement of sliding block 22, the rotating sleeve 20 itself begins to rotate, thereby pushing sliding block 23, which is tightly connected to it and fixed to one end of the fixed plate 17, to slide stably along its inner wall. The sliding of sliding block 23 pushes the fixed plate 17 to slide along the preset slide rail on the side wall of the base 1, allowing the brush 18 and scraper 19 to work together to clean the gate 4. The brush 18 has fine and elastic bristles that can reach deep into the gaps, grooves, and tiny pits on the surface of the gate 4, gently sweeping away tightly attached, small, and difficult-to-remove debris such as silt particles and flocculent algae. This prevents these tiny debris from adhering for a long time and corroding the surface of the gate 4, ensuring the smoothness of the gate 4 and maintaining its good physical properties. The scraper 19 has a certain rigidity and sharp edges, which can powerfully scrape away larger, more adhesive debris from the surface of the gate 4. It complements the fine cleaning of the brush 18, and the two work together to clean the gate 4 in a comprehensive and efficient manner, ensuring that the gate 4 is restored to its best condition after cleaning and eliminating potential hazards for the subsequent stable operation of the dam.

[0038] Working principle: When using this equipment, activating the gate opener 2 causes the screw 3 to slide downwards, pushing the gate 4 downwards and thus blocking the river water. The filter screen 6 installed on the side wall of the base 1 effectively prevents debris from accumulating near the gate 4, preventing damage to the gate 4's sealing structure and guide rails. When the filter screen 6 needs replacement, rotating the rotating block 7 drives the pull rope 8 to rotate, pulling the connecting block 9 and causing the fixing ring 10 to slide towards the center, compressing the spring 13. This allows the locking block 11 to detach from the mounting base 5, releasing the fixing effect on the filter screen 6. At this point, the filter screen 6 can be removed and replaced by pulling it upwards. When it is necessary to clean the gate 4, the gate 4 is moved upwards by the opening and closing device 2. Then, the starting motor 16 drives the rotating plate 21 to rotate, allowing it to slide inside the rotating sleeve 20. This causes the rotating sleeve 20 to start rotating and push the sliding block 23 to slide, which in turn pushes the fixing plate 17 to start sliding. This allows the brush 18 and the scraper 19 to work together to clean the gate 4.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
