Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a garbage interception device used in water conservancy projects. Background Art

[0002] Waste interception is crucial in water conservancy projects, primarily to prevent clogging facilities, affecting water quality, and ensuring water safety downstream. Litter such as plastic, branches, and fallen leaves can have serious impacts on water conservancy projects if not promptly handled.

[0003] Chinese patent publication number CN119615861B discloses a river solid waste interception system. This system uses a floating interception mechanism to transport water and waste in the river away from the water inlet pipe to the water inlet pipe. The water and waste enter the inner side of the mesh cylinder in the main cylinder from the water inlet pipe and flow in a rotational manner. The mesh cylinder intercepts the waste in the water, and the water passes through the mesh cylinder and flows back into the river from the outlet pipe, thereby achieving the effect of intercepting the waste in the river. The entire process can be achieved only through the natural flow of the water body, without the need for an additional power source, and is easy to maintain.

[0004] However, the above-mentioned publicly available solutions have the following drawbacks: The operation of the multiple rotating components is entirely dependent on the impact of the water flow. In rivers with gentle currents, the current cannot drive the rotating components properly, resulting in functional failure and limited scope of use. The rotating components are easily entangled by strips of garbage, causing them to become stuck and unable to rotate properly, which also significantly reduces the garbage interception function. Furthermore, the amount of garbage accumulated in the net is relatively small, requiring frequent cleaning, which also affects its effectiveness. Summary of the Invention

[0005] The present invention aims to address the problems in the background art that rotating parts rely on high-speed water flow and are easily stuck and fail, and require high-frequency regular cleaning, and propose a garbage interception device for water conservancy projects.

[0006] The technical solution of the present invention is a garbage interception device for water conservancy projects, comprising:

[0007] Two sets of vertical guide rails are provided, and the two sets of vertical guide rails are respectively provided on both sides of the water flow. Flat plates are provided on the vertical guide rails, and the flat plates are located above the water bank;

[0008] Two arc-shaped guide rails are provided and are respectively arranged on the top of the two vertical guide rails, and flat guide rails are respectively provided at the lower ends of the two arc-shaped guide rails;

[0009] The grille has sliding mechanisms on both the top and bottom sides. The bottom sliding mechanism is slidably connected to the vertical guide rail, and the top sliding mechanism is slidably connected to the curved guide rail and the flat guide rail. A horizontal anti-overflow grille is set on the water-facing surface of the top of the grille.

[0010] The lifting mechanism is arranged on the flat plate, and the lifting mechanism drives the sliding mechanism at the bottom of the grille to move upward;

[0011] and an electrical cabinet, which is arranged on the flat plate, wherein a control system is arranged in the electrical cabinet, and the control system is connected to the lifting mechanism control;

[0012] In the initial stage of garbage interception, the grille is in a vertical state. As the amount of garbage intercepted increases, the resistance that the grille needs to resist gradually increases. As the resistance continues to increase, the upper end of the grille flips toward the back water side, increasing the water surface and the garbage interception surface. When the amount of garbage intercepted is large, the bottom of the grille is controlled to rise through the lifting device. At this time, the sliding mechanism on the top of the grille slides along the flat guide rail, and the grille gradually tends to be horizontal and leaves the water surface. At this time, the garbage on the grille can be easily cleaned off.

[0013] Preferably, a bottom plate is provided at the bottom of the vertical guide rail, and the bottom plate is connected to the underwater concrete structure through a plurality of expansion bolts; and guide rail reinforcement plates are provided on the outer sides of the ends of the two flat guide rails.

[0014] Preferably, the sliding mechanism includes a connecting rod arranged on the vertical outer side of the grille, and a ball head arranged at the end of the connecting rod; the vertical guide rail, the arc guide rail and the flat guide rail are all provided with a strip groove for the connecting rod to pass through and a sliding groove for the ball head to be inserted.

[0015] Preferably, the lifting mechanism includes a spherical shell that is sleeved on the ball head and located in the slide groove, a wire rope connecting seat arranged on the top of the spherical shell, a motor arranged on the flat plate, a winding wheel arranged on the motor output shaft, and a wire rope connected to the wire rope connecting seat and wound around the winding wheel.

[0016] Preferably, a first pressure sensor and a second pressure sensor are respectively provided at the end of the arc guide rail and the end of the flat guide rail, and the sliding mechanism at the top of the grille squeezes the first pressure sensor when it slides to the end of the arc guide rail, and squeezes the second pressure sensor when the sliding mechanism at the top of the grille slides to the end of the flat guide rail.

[0017] Preferably, the grille includes a square frame and interception transverse plates arranged side by side and equidistantly in the square frame; the grille is provided with a garbage cleaning mechanism for pushing the garbage intercepted thereon to the shore.

[0018] Preferably, the garbage cleaning mechanism includes a support plate, and a plurality of rods arranged on the water-facing and water-receiving surfaces of the support plate, the rods on the water-receiving surface are inserted between two adjacent intercepting cross plates, and an operating rod is horizontally arranged on the support plate.

[0019] Preferably, the support plate and the end of the operating rod are detachably connected to both sides of the grille. By holding the operating rod and pulling it back and forth, the garbage trapped on the grille can be pulled or pushed to the banks on both sides through the insertion rod, and the garbage on the grille can be quickly cleaned.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] It does not rely on high-speed water flow. As the amount of garbage intercepted increases, the resistance on the screen will become greater and greater, continuously pushing the screen to flip clockwise. This flip does not require the impact of high-speed water flow and can be stable.

[0022] The gradually inclined screen will increase the water-facing surface and improve the garbage interception area, thereby continuously increasing the garbage interception volume, while reducing the resistance and preventing the screen from being deformed and damaged by large forces;

[0023] The grille is continuously tilted to increase the garbage interception area. Three-quarters of the grille is the garbage interception surface, which can intercept a large amount of garbage, helping to reduce the frequency of garbage cleaning and making it more practical.

[0024] By setting up a garbage cleaning mechanism and holding the operating lever and pushing and pulling it back and forth, the garbage on the grille can be quickly pushed to the banks on both sides, making it very convenient to clean the grille. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] Example 1, as Figures 1-4 As shown, the present invention proposes a garbage interception device for water conservancy projects, comprising:

[0034] Two sets of vertical guide rails 1 are provided. The two sets of vertical guide rails 1 are respectively provided on both sides of the water flow. A flat plate 7 is provided on the vertical guide rails 1. The flat plate 7 is located above the water bank. In order to improve the stability of the vertical guide rails 1, a shore reinforcement frame 8 is provided on the shore. The flat plate 7 and the shore reinforcement frame 8 are connected by a plurality of connecting bolts 11.

[0035] Two arc-shaped guide rails 3 are provided and are respectively arranged on the top of the two vertical guide rails 1, and flat guide rails 4 are respectively provided at the lower ends of the two arc-shaped guide rails 3;

[0036] The grille 6 is provided with sliding mechanisms on both the top and bottom sides. The bottom sliding mechanism is slidably connected to the vertical guide rail 1, and the top sliding mechanism is slidably connected to the arc guide rail 3 and the flat guide rail 4. A horizontal anti-overflow grille 10 is provided on the water-facing surface of the top of the grille 6. The anti-overflow grille 10 can prevent the intercepted garbage from flowing over the top of the grille 6 and flowing to the rear during the deflection of the grille 6;

[0037] The lifting mechanism is provided on the flat plate 7, and the lifting mechanism drives the sliding mechanism at the bottom of the grille 6 to move upward;

[0038] and an electrical cabinet 20, which is arranged on the flat plate 7, wherein a control system is arranged in the electrical cabinet 20, and the control system is connected to the lifting mechanism control;

[0039] Furthermore, a bottom plate 2 is provided at the bottom of the vertical guide rail 1, and the bottom plate 2 is connected to the underwater concrete structure through multiple expansion bolts. If the bottom of the water is not a concrete structure, concrete piles can be poured at the required position and then the bottom plate 2 can be connected to the concrete piles; guide rail reinforcement plates 5 are provided on the outer sides of the ends of the two flat guide rails 4, and the guide rail reinforcement plates 5 are connected to the shore facilities, or a support frame is provided on the shore, and then the guide rail reinforcement plates 5 are connected to the support frame, a structure similar to the shore reinforcement frame 8 can be obtained.

[0040] The flat plate 7 is higher than the water surface, and the grille 6 is also higher than the water surface. In the initial stage of garbage interception, the grille 6 is in a vertical state. As the amount of garbage intercepted increases, the resistance that the grille 6 needs to resist gradually increases. As the resistance continues to increase, the upper end of the grille 6 flips toward the back of the water, increasing the water surface, increasing the garbage interception surface, and reducing the resistance; when the amount of garbage intercepted is large, the bottom of the grille 6 can be controlled to rise by the lifting device. At this time, the sliding mechanism on the top of the grille 6 slides along the flat guide rail 4, and the grille 6 gradually tends to be horizontal and leaves the water surface. At this time, the garbage on the grille 6 can be easily cleaned off.

[0041] Example 2, as Figure 1 、 Figure 2 and Figure 6 As shown, the present invention proposes a garbage interception device for water conservancy projects. Compared with the first embodiment, this embodiment introduces the structures of the sliding mechanism and the lifting mechanism in detail.

[0042] The sliding mechanism includes a connecting rod 12 arranged on the vertical outer surface of the grille 6, and a ball head 13 arranged at the end of the connecting rod 12; the vertical guide rail 1, the arc guide rail 3 and the flat guide rail 4 are all provided with a strip groove for the connecting rod 12 to pass through and a slide groove for the ball head 13 to be inserted. The cross-section of the slide groove is a circle with a notch, and the notch is just connected to the strip groove.

[0043] The lifting mechanism includes a ball shell 14 that is sleeved on the ball head 13 and located in the slide groove, a wire rope connecting seat 15 arranged on the top of the ball shell 14, a motor 17 arranged on the flat plate 7, a winding wheel arranged on the output shaft of the motor 17, and a wire rope 16 connected to the wire rope connecting seat 15 and wound on the winding wheel. An avoidance hole for the wire rope 16 to pass through is provided on the vertical guide rail 1; the control system is connected to the motor 17, and the motor 17 is an encoder motor, which is convenient for controlling its rotation angle, thereby controlling the rising height of the bottom of the grille 6.

[0044] Example 3, as Figure 1 、 Figure 5 and Figure 7 As shown, the present invention proposes a garbage interception device for water conservancy projects. Compared with the first embodiment, this embodiment introduces the garbage cleaning related structure on the grille 6 in detail.

[0045] A first pressure sensor 18 and a second pressure sensor 19 are respectively provided at the end of the curved guide rail 3 and the end of the flat guide rail 4. When the sliding mechanism at the top of the grille 6 slides to the end of the curved guide rail 3, the first pressure sensor 18 is squeezed, and when the sliding mechanism at the top of the grille 6 slides to the end of the flat guide rail 4, the second pressure sensor 19 is squeezed. The control system is connected to the first pressure sensor 18 and the second pressure sensor 19 for signal transmission. After the first pressure sensor 18 is squeezed, the control system drives the bottom of the grille 6 to move upward at a set speed through the lifting mechanism until it moves to 0.3 meters below the liquid surface. The rising speed of the bottom of the grille 6 is reasonably controlled according to the amount of garbage in the water. In the present invention, it takes 24 hours for the bottom of the grille 6 to rise to 0.3 meters below the liquid surface from the beginning of its upward movement to 0.3 meters below the liquid surface, ensuring that it still has a garbage interception function, preventing the operator from failing to clean the garbage on the grille 6 and reset the grille 6 in time. When the first pressure sensor 18 is squeezed, the control system sends an alarm message to the remote terminal to remind relevant personnel to clean the garbage on the grille 6 in time.

[0046] The grille 6 includes a square frame and intercepting horizontal plates 9 arranged side by side and equidistantly within the square frame; the grille 6 is provided with a garbage cleaning mechanism 21 for pushing the garbage trapped thereon toward the shore. The garbage cleaning mechanism 21 includes a support plate 22 and a plurality of insertion rods 23 provided on the water-facing and water-repelling surfaces of the support plate 22. The insertion rods 23 on the water-repelling surface are inserted between two adjacent intercepting horizontal plates 9. An operating rod 25 is provided horizontally on the support plate 22. By holding the operating rod 25 and pulling it back and forth, the garbage trapped on the grille 6 can be pulled or pushed toward the shore on both sides through the insertion rods 23, quickly completing the garbage cleaning on the grille 6. In the garbage cleaning state, the grille 6 is nearly horizontal, making it very convenient to hold the operating rod 25 and pull it back and forth in this state.

[0047] Furthermore, the ends of the support plate 22 and the operating rod 25 are respectively detachably connected to the two sides of the grille 6, which makes it easy to quickly remove the garbage cleaning mechanism 21 to perform garbage cleaning operations, and after it is connected to the grille 6, it can be stably fixed on the grille 6 and rotate with the grille 6; specifically, a fixing plate 24 is provided on the grille 6, and a plurality of positioning holes are horizontally provided on the fixing plate 24, and a plurality of positioning rods are provided on the support plate 22, and the positioning rods are inserted into the positioning holes. A limiting seat 26 is provided on the other side of the grille 6, and the operating rod 25 is against the limiting seat 26, and the operating rod 25 is pressed by rotating the connected pressure plate 27. The pressure plate 27 and the limiting seat 26 are connected by a locking bolt 28. When in use, unscrew the locking bolt 28, open the pressure plate 27, and the operating rod 25 can be taken out and pushed and pulled back and forth.

[0048] In summary, when the present invention is in use, the grille 6 is in a vertical state at the initial stage of garbage interception. As the amount of garbage interception increases, the resistance that the grille 6 needs to resist gradually increases. As the resistance continues to increase, the grille 6 first flips clockwise to increase the water-facing surface, increase the garbage interception surface, and thus increase the garbage interception amount, while reducing the resistance to prevent the grille 6 from deformation and damage. When the first pressure sensor 18 is squeezed, the motor 17 starts and drives the bottom of the grille 6 upward at a set speed until it moves to 0.3 meters below the liquid surface. The bottom of the grille 6 rises to 0.3 meters below the liquid surface to ensure that it still has the garbage interception function. When the first pressure sensor 18 is squeezed, the control system sends an alarm message to the remote terminal, reminding relevant personnel to clean up the garbage on the grille 6 in time. After the garbage cleaning personnel arrive at the scene, they further control the motor 17 through the control system to lift the grille 6 as a whole above the water surface. After the second pressure sensor 19 is squeezed, the motor 17 stops working. At this time, the operator unscrews the locking bolt 28, opens the pressure plate 27, and holds the operating lever 25 and pulls it back and forth to push the garbage trapped on the grille 6 to the two banks. After cleaning, the garbage cleaning mechanism 21 is fixed to the grille 6 and the control system reverses the motor 17. The grille 6 moves downward under its own weight and flips counterclockwise until the grille 6 reaches the lowest point. If the grille 6 gets stuck during the flipping and reset process, the anti-overflow grille 10 can be pushed to help the grille 6 reset. In the present invention, the gradually changing angle of the grille 6 has the following advantages over a vertical, fixed grille: efficient interception, the tilted design increases the contact area with the water flow, improving the efficiency of garbage interception, and is particularly suitable for high-flow areas; adaptive adjustment, automatic tilting as the amount of garbage increases, dynamic adjustment to avoid overload, and extended service life; reduced resistance, the tilt angle reduces overall resistance, reduces obstruction to the water flow, and avoids blockage and damage. Compared to grilles tilted at a fixed angle, it has the following advantages: dynamic adjustment, constantly adapting to the amount of garbage intercepted, continuously releasing pressure, helping to increase service life and prevent deformation and damage to the grille 6; timely cleaning, after flipping to a certain angle, a signal is triggered, reminding relevant personnel to promptly clean the garbage trapped on the grille 6; simple cleaning, the grille 6 can be flipped to a near-horizontal state, and the garbage on it can be quickly pushed to the banks on both sides by the garbage cleaning mechanism 21.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
