Technical Field

[0001] This invention relates to the technical field of cleaning devices for water conservancy project spillway systems, and particularly to an integrated anti-blocking device for water conservancy dam spillway systems. Background Technology

[0002] Dams, as hydraulic structures that intercept rivers or regulate water flow, can form reservoirs, raise water levels, regulate runoff, and concentrate water head for purposes such as flood control, water supply, irrigation, hydropower generation, and improving navigation.

[0003] During the water storage process, debris such as dead branches, leaves, and plastic waste can easily float downstream from the dam and accumulate at the gates of the dam's spillway or water diversion structure. Over time, this accumulation can cause blockages at the gates, reducing the discharge capacity and even endangering the dam's safety. Therefore, timely cleaning is necessary. Currently, the cleaning of surface debris is mostly done manually or by salvage boats, which is slow, time-consuming, and inconvenient. Summary of the Invention

This device can intercept and clean up surface debris in front of the spillway structure, and improves work efficiency and reduces cleaning time by collecting and cleaning debris. It also meets the requirements of routine interception operations, ensures spillway capacity, and has high adaptability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is that the device integrates a groove and a spillway anti-blocking module on the dam body, and works in conjunction with the gate working space of the dam body to prevent spillway blockage; it includes:

[0006] The dam body has symmetrical grooves on the side wall at the outlet of the dam body, and a support is provided above the grooves;

[0007] A filter assembly is connected to a support at the top and submerged in water at the bottom. It forms a cylindrical structure with a notch as it rises along the groove. A floating plate is provided at the bottom of the filter assembly.

[0008] A cleaning component, which is installed on the side of the bracket and can clean the debris inside the filter assembly;

[0011] Preferably, the filter cartridge has sliders symmetrically arranged at both ends, and the groove has a sliding groove connected to the sliders inside; the two ends of the floating plate are respectively connected to the sliding groove, and the middle part has a floating component.

[0015] Preferably, the mounting plate is provided with a positioning sleeve that is connected to the wire rope, and a contact platform is provided above the mounting plate.

[0016] Preferably, the thrust member includes a second hydraulic cylinder connected to the bracket and a positioning column installed at the end of the second hydraulic cylinder; the positioning column is provided with a side push plate.

[0017] Preferably, a positioning baffle is provided on the bracket above the second hydraulic cylinder, and guide grooves are symmetrically provided on both sides of the positioning baffle; the positioning column is provided with a guide column connected to the guide groove.

[0018] Preferably, a first support wheel is provided above the positioning baffle, located on one side of the wire rope and in contact with it; a second support wheel is provided on the bracket, located on the other side of the wire rope.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. By casting grooves into the dam body, the entire device can be installed, which can match the installation operations of various dams. At the same time, the working parts are located above the dam body, which can be combined with the working space of traditional gates, making it highly adaptable.

[0021] 2. The filter components are arranged in the water and extend above the water surface, which can effectively block the garbage coming down from upstream, without affecting the normal waterproofing requirements of the dam. When a large amount of garbage accumulates, the rising filter cylinder, together with the sliding wall, concentrates the garbage in the cylindrical structure for collection. Then, with the synergistic action of the cleaning and thrusting components, the garbage in the cylinder is discharged to the designated location, which effectively improves the salvage efficiency and requires no personnel intervention.

[0022] 3. When the filter cylinder is being lifted for retrieval, the floating plate rises along with it under the action of buoyancy and floats to the water surface. It can replace the filter cylinder to intercept residual garbage, improve the reliability of the overall cleaning, and prevent residual garbage from floating out and clogging the water channel.

[0023] 4. The collected garbage gathers in the cylindrical space formed by the filter cylinder and the sliding wall. By pulling the scraper on the wire rope, the garbage inside can be quickly cleaned, thereby improving the cleaning efficiency.

[0024] 5. The thrust component can connect with both ends of the filter cylinder and simultaneously push the filter cylinder and cleaning component to adjust their displacement, so that the end of the filter cylinder is located outside the dam body, which facilitates the discharge of garbage. After the thrust component is connected, it can ensure the stability of the filter cylinder and prevent the filter cylinder from swaying left or right during the cleaning process, thus improving stability.

[0025] 6. The cleaning components adopt the form of steel wire rope connecting scrapers, which can meet the cleaning needs of dams of different specifications. When moving with the filter cartridge, the displacement can be adjusted by changing the distance of the steel wire rope. The design is reasonable and the structure is compact.

[0026] 7. The sliding wall, relying on the cooperation between the buoyancy part and the counterweight part, can follow the position of the filter cartridge and automatically adjust the sliding wall to complete the requirements of unfolding or resetting. The structure is ingeniously designed. Attached Figure Description

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0047] Specific implementation method one: Combining Figure 1-18 As shown, an integrated water conservancy dam spillway anti-blocking device is constructed by integrating grooves and spillway anti-blocking modules on the dam body. It works in conjunction with the gate working space of the dam body to prevent spillway blockage. The device includes a dam body 1, with grooves 101 symmetrically arranged on the side wall at the outlet of the dam body 1, and a support 102 above the grooves 101; a filter assembly 2, which is connected to the support 102 at the top and is used to intercept garbage at the bottom, which is submerged in the water surface. As it rises along the grooves 101, it unfolds to form a cylindrical structure with notches. A floating plate 3 is provided below the filter assembly 2; a cleaning component 4, which is installed on the side of the support 102 and can clean the garbage inside the filter assembly 2; and a thrust component 5, which is installed in pairs on the support 102 and can push the filter assembly 2 and the cleaning component 4 to a horizontal position, so that the internal garbage can fall off after reaching the designated position, thus realizing the cleaning operation.

[0048] Preferred embodiments, in combination Figure 1-6 As shown, the filter assembly 2 includes a filter cylinder 201 and a first winding device 202. The filter cylinder 201 is semi-circular and has a rotatable sliding wall 203 on its outer wall. The sliding wall 203 is slidably connected to the filter cylinder 201. The length of the sliding wall 203 is less than the length of the filter cylinder 201, and is at least the width distance between two grooves 101, which is the same as the width dimension of the dam body 1. The sliding wall 203 is provided with a buoyancy part 204 and a counterweight part 205 in sequence. The buoyancy generated by the buoyancy part 204 is greater than the downward thrust generated by the counterweight part 205. The two ends of the filter cylinder 201 are connected to the support 102 by steel wire ropes. The first winding device 202 is connected to the filter cylinder 201. The first winding device 202 drives the filter cylinder 201 to move up and down through the steel wire rope to achieve height adjustment control. When the filter cylinder 201 rises and gradually leaves the water surface, the buoyancy generated by the buoyancy part 204 decreases, which is less than the downward thrust of the counterweight part 205, thereby pushing the sliding wall 203 to rotate and unfold, forming a cylindrical structure before leaving the water surface, realizing the retrieval operation of floating garbage in the water surface, quickly completing the retrieval, and using the first winding device 202 to lift it to the designated height to wait for the cleaning operation; wherein, the filter cylinder 201, the sliding wall 203 and the floating plate 3 all have filter holes for water to flow through.

[0049] Preferred embodiments, in combination Figure 3-4As shown, the filter cylinder 201 has symmetrical sliders 206 at both ends. The groove 101 of the dam body 1 has a pre-arranged vertical groove 103. The groove 103 and the slider 206 are slidably connected to achieve the positioning of the filter cylinder 201 without affecting the up and down displacement of the filter cylinder 201, effectively improving the stability during garbage interception. At the same time, the two ends of the floating plate 3 also have sliders 206 to connect with the groove 103, and the middle is provided with an upper floating member 301. During the upward movement of the filter cylinder 201, the floating plate 3 moves upward synchronously under the buoyancy of the upper floating member 301, which can effectively block residual garbage and ensure the cleanliness of the discharged water. The upper floating member 301 is located in the middle area of ​​the floating plate 3, so that after the upper floating member 301 reaches the water surface, there is a certain blocking area above the floating plate 3 to prevent garbage from passing through.

[0050] Preferred embodiments, in combination Figure 6 and Figure 17 As shown, the filter cylinder 201 has a positioning groove 207 on its outer wall. When the sliding wall 203 slides from the upper end to the lower end of the positioning groove 207, it prevents the sliding wall 203 from continuing to rotate, thus preventing the buoyancy part 204 from deflecting to the right side of the filter cylinder 201 and causing the filter cylinder to be unable to reset due to buoyancy.

[0051] Preferred embodiments, in combination Figure 7-12 As shown, the cleaning component 4 includes a telescopic arm 401 and a mounting plate 402. The telescopic arm 401 is bolted to the bracket 102 and is arranged symmetrically. A second winding device 403 is installed on one side of the telescopic arm 401, and the two second winding devices 403 are connected by a wire rope. A scraper 404 is installed on the wire rope, and a control hydraulic cylinder 405 is arranged at the rear end of the telescopic arm 401. The mounting plate 402 is installed at the front end of the telescopic arm 401 and connected to the wire rope. By controlling the winding and unwinding of the wire rope between the two second winding devices 403, the scraper 404 is moved to a different position. 04. In the cylindrical structure formed by the filter cylinder 201 and the sliding wall 203, the internal garbage is pushed from one end to the other, achieving rapid discharge of garbage. Moreover, the scraper 404 is fixed by steel wire rope, which is not limited by the span of the dam body 1 and can adapt to the installation operation of dam body 1 of different sizes. When the span is too large, the steel wire rope will sag. In order to ensure that the scraper 404 can smoothly enter the interior of the filter cylinder 201, the diameter of the scraper 404 can be reduced. Even after the reduction, the scraper 404 still prioritizes contact with the lower part of the inner wall of the filter cylinder 201 under the action of sag, which will not affect the cleaning operation.

[0052] Preferred embodiments, in combination Figure 12As shown, the scraper 404 has a rotating sleeve 406 fixedly connected to the wire rope at its center. The rotating sleeve 406 is rotatably connected to the center of the scraper 404. At the same time, multiple blades 407 are provided along the circumference of one side of the scraper 404, and multiple nozzles 408 are provided on the other side. The nozzles 408 are connected to the water supply pipeline to generate high-pressure water flow. When the wire rope pulls the scraper 404 to move, the blades 407 can cut off the branches stuck in the filter holes, thereby improving the stability of the movement. Then the nozzles 408 perform spraying and washing operations again to clean the inside of the filter holes and prevent clogging.

[0053] Preferred embodiments, in combination Figure 10 and Figure 11 As shown, the mounting plate 402 is provided with a positioning sleeve 409 that is connected to the wire rope. The wire rope for fixing the scraper 404 passes through the positioning sleeve 409 to guide and position the wire rope and ensure the stability of its displacement. At the same time, a contact platform 6 is provided above the mounting plate 402 to contact the thrust member 5 and receive force to achieve synchronous displacement.

[0054] Preferred embodiments, in combination Figure 13 and Figure 14 As shown, the thrust member 5 includes a second hydraulic cylinder 501 connected to the bracket 102 and a positioning column 502 installed at the end of the push rod in the second hydraulic cylinder 501. A side push plate 503 is welded on the positioning column 502. The positioning column 502 is pushed by the second hydraulic cylinder 501 to contact the hole in the slider 206, thereby achieving docking with the filter cartridge 201. At the same time, when the filter cartridge 201 is pushed to move, the side push plate 503 contacts the contact table 6 synchronously, achieving the effect of pushing the displacement simultaneously, thus eliminating the need for additional power components. Specific Implementation Method Two

[0056] Combination Figure 13-15 As shown, when the first winding device 202 pulls the filter cylinder 201 upward, it is prone to swaying in windy weather, which makes it impossible for the thrust member 5 to dock with the filter cylinder 201. By installing a positioning baffle 504 on the bracket 102 above the second hydraulic cylinder 501, when the filter cylinder 201 is pulled upward, the upper surface of the slider 206 contacts the lower surface of the positioning baffle 504. With the tension of the wire rope, the filter cylinder 201 is positioned, improving stability. Furthermore, the positioning baffle 504 is symmetrically provided with guide grooves 505 on both sides, and the positioning post 502 is provided with a guide post 506 connected to the guide groove 505. The sliding connection between the two assists in supporting and positioning the positioning post 502, reducing the force on the second hydraulic cylinder 501, preventing bending, and improving the stability of the structure. Specific Implementation Method 3

[0058] Combination Figure 13As shown, in order to improve the stability of the first winding device 202 when driving the filter cylinder 201 to adjust its height, a first support wheel 507 is provided above the positioning baffle 504, located on one side of the wire rope and in contact with the wire rope, and a second support wheel 104 is provided on the bracket 102, located on the other side of the wire rope and in contact with it. Through the cooperation between the two, the wire rope is positioned to prevent it from shaking. In addition, the installation of the second support wheel 104 can also prevent the wire rope from rubbing against the bracket 102 during the displacement of the filter cylinder 201 by the thrust member 5, thus avoiding the occurrence of breakage. Specific Implementation Method Four

[0060] Regarding the structure of the telescopic boom, combined with... Figure 10 and Figure 11 As shown, the telescopic boom 401 includes an outer sleeve and an inner sleeve rod; a second winding device 403 is installed on the outer sleeve, and one end of the inner sleeve rod is connected to the mounting plate 402, while the other end is in contact with the control hydraulic cylinder 405. At the same time, a return spring is sleeved on the inner sleeve rod, which is in contact with the right end of the outer sleeve; the position of the mounting plate 402 can be actively changed by controlling the extension and retraction of the control hydraulic cylinder 405. Detailed Implementation Method Five

[0062] Regarding the arrangement of the buoyancy unit 204, in conjunction with... Figure 4 and Figure 17 As shown, the sliding wall 203 has a semi-circular circular plate structure. The buoyancy part 204 needs to be arranged in the upper area, at least at a horizontal line of 90 degrees. If it is too low, the sliding wall 203 will unfold too slowly during the rise of the filter cylinder 201, resulting in the inability to collect garbage on the water surface. The buoyancy part 204 and the floating part 301 can adopt the design of airbags, while the counterweight part 205 uses metal blocks to increase weight. Specific Implementation Method Six

[0064] Combination Figure 14 and Figure 16 As shown, the slider 206 has holes that are compatible with the positioning post 502 for docking between the two. After the positioning post 502 is inserted into the hole, it limits the axial direction of the filter cartridge 201 and improves the stability of the filter cartridge 201 itself during the cleaning process. Detailed Implementation Method Seven

[0066] Combination Figure 1 As shown, in order to facilitate centralized collection and treatment of garbage, a material drop channel is arranged on the dam body 1. The material drop channel is located in the displacement direction of the filter cylinder 201, and its size is approximately the same as the groove. When the thrust member 5 pushes the filter cylinder 201 to the top of the material drop channel, the scraper 404 pushes the garbage out of the filter cylinder 201 and drops it. Detailed Implementation Method Eight

[0068] The first winding device 202 and the second winding device 403 can adopt the structural design of a winch, and in the position of the wire rope, combined with Figure 10 As shown, support wheels are also added to support and guide the wire rope. Detailed Implementation Method Nine

[0070] Combination Figure 8 As shown, the filter cartridge 201 has a notch at the lower left end, which allows the scraper 404 to push the internal waste down, so as to facilitate the smooth discharge of waste and increase the material discharge space. Detailed Implementation Method Ten

[0072] Combination Figure 9 As shown, the control hydraulic cylinder 405 and the inner sleeve rod in the telescopic arm 401 are in surface contact connection. By extending the control hydraulic cylinder 405, the telescopic arm 401 is pushed to extend. When the control hydraulic cylinder 405 is reset, the elastic force of the reset spring is used to retract it. At the same time, when the thrust member 5 pushes the telescopic arm 401 to extend, the control hydraulic cylinder 405 does not need to work. At this time, the inner sleeve rod and the push rod of the control hydraulic cylinder 405 are in a separated state.

[0073] The specific work steps are as follows:

[0074] After the overall structure is installed on the support 102, the two sets of first winding devices 202 on the support 102 are activated simultaneously. The filter cylinder 201 and the sliding wall 203 move downwards by their weight. When they come into contact with the water surface, the steel wire rope is released to ensure that the water surface is at least in the middle of the filter cylinder 201. At the same time, as the filter cylinder 201 moves downwards, the weight of the filter cylinder 201 pushes the floating plate 3 to go deep into the water along the chute 103 to filter and intercept the bottom area. At this time, the sliding wall 203, under the buoyancy of the buoyancy part 204, overcomes the gravity of the counterweight part 205 and is in a contracted state. During normal operation, the garbage floating from upstream is intercepted at the filter cylinder 201. The normal water supply operation of the dam will not be affected during the filtration process.

[0075] When there is a lot of garbage, the first winding device 202 is activated, which drives the wire rope to wind up and reset, lifting the filter cylinder 201 to float to the surface. During the upward movement of the filter cylinder 201, due to the change in the contact position between the buoyancy part 204 and the water surface, the sliding wall 203 is pushed to gradually unfold underwater under the action of the counterweight part 205. Thus, when it leaves the water surface, the garbage gathered at the water surface can be retrieved, achieving rapid retrieval. At the same time, the floating plate 3 located below the filter cylinder 201 moves upward with the filter cylinder 201 under the action of buoyancy. Since the upper surface of the floating plate 3 is in contact with the sliding wall 203, it will not affect its unfolding. Thus, after the filter cylinder 201 leaves the water surface, the floating plate 3 can intercept the remaining garbage to float by, effectively ensuring the reliability of the cleaning.

[0076] Before the slider 206 of the filter cartridge 201 is about to contact the positioning baffle 504, the control hydraulic cylinder 405 pushes the telescopic arm 401 to extend. The second winding device 403 simultaneously releases the corresponding length of wire rope, so that the position of the wire rope is offset from directly above the filter cartridge 201 to avoid interference. After the slider 206 contacts and is positioned with the positioning baffle 504, the control hydraulic cylinder 405 is reset, and the telescopic arm 401 is reset under the action of the reset spring. At this time, the center of the scraper 404 coincides with the center of the filter cartridge 201.

[0077] Activate thrust component 5, and the second hydraulic cylinder 501 pushes the positioning column 502 to align with the hole on the slider 206, thus supporting and positioning the filter cylinder 201. At this time, the side push plate 503 and the contact platform 6 on the mounting plate 402 simultaneously contact each other. Then, the second hydraulic cylinder 501 pushes the filter cylinder 201 to move towards the material discharge channel. During the displacement, the first winding device 202 and the second winding device 403 simultaneously release the wire rope. Moreover, during the displacement, the wire rope of the first winding device 202 also limits the filter cylinder 201 to prevent it from falling off, effectively ensuring the stability of the displacement. After reaching the material discharge channel, one of the two sets of second winding devices 403 releases the wire rope while the other winds it up, thereby driving the scraper 404 into the cylindrical structure formed by the filter cylinder 201 and the sliding wall 203, pushing the garbage inside out from the left end of the filter cylinder 201 and dropping it into the material discharge channel, thus achieving a rapid cleaning operation. After cleaning, the filter cylinder 201 can be reset sequentially.

[0078] In summary, compared with traditional cleaning operations, this technical solution has stronger applicability. By adjusting the extension of the wire rope and the size of the filter cylinder 201, the installation and use requirements of dams 1 with different spans can be met. At the same time, the normal water supply operation of dam 1 will not be affected during the interception process. Even during the cleaning operation, dam 1 can still carry out drainage operations to ensure the discharge capacity. During filtration, relying on the ingenious structural design of the filter cylinder 201 and the sliding wall 203, the buoyancy and gravity changes caused by the rise after interception can realize the salvage operation. At the same time, with the help of the floating plate 3, the residual garbage is intercepted, ensuring the reliability of filtration. Then, by adjusting the position, the overall cleaning operation is completed. By adding a control system, automatic cleaning operation can also be realized, which greatly improves work efficiency and reduces the difficulty of operation. This technical solution can also be applied to the ecological management of rivers. By arranging the support 102 on both banks of the river, the garbage on the water surface can be intercepted and cleaned.
