Description

Technical Field

[0001] This application relates to the field of reservoir gate technology, specifically a floating debris collection device for reservoir gates. Background Technology

[0002] There are many floating objects in waterways, including garbage and plastics. If these floating objects are not managed for a long time, they will pollute the environment, greatly reduce water resources, and cause microorganisms to grow if the water does not flow for a long time.

[0003] An existing patent (publication number: CN223033971U) discloses a floating debris collection device for reservoir gates, comprising multiple fixed frames, each with a net sleeve fixed to it. A securing rope is attached to the end of the net sleeve furthest from the fixed frame. A fixing plate is fixed between adjacent fixed frames, and a height adjustment mechanism is fixed to the fixing plate. In use, this invention utilizes the assistance of multiple fixed frames and net sleeves to intercept and collect floating debris flowing between adjacent gate piers. Workers only need to periodically clean the floating debris collected in the net sleeves, significantly reducing their working time.

[0004] The aforementioned device, with the assistance of multiple fixed frames and multiple net sleeves, intercepts and collects floating debris in the water flowing between two adjacent sluice gates. Staff can periodically clean the floating debris collected in the multiple net sleeves. However, during use, when the reservoir span is large and there are many net sleeves, when the net sleeves are full, it is necessary to manually untie and collect the ropes one by one and clean them, which is inefficient. Moreover, adjacent net sleeves are prone to entanglement due to the impact of water flow, which can lead to leakage of floating debris or obstruction of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a floating debris collection device at a reservoir gate, which has advantages such as automatic conveying of floating debris and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a floating debris collection device at a reservoir gate, comprising a set of gate piers, with a lifting frame installed at one end of the two outermost gate piers, a drive shaft rotatably connected between the inner top wall and the inner bottom wall of the two lifting frames, and pulleys fixedly connected to the top and bottom ends of the two drive shafts, with belt drives connecting the two uppermost pulleys and the two lowermost pulleys respectively.

[0007] An intercepting net is fixedly connected between the two belts on their sides that are close to each other, and the cross-section of the intercepting net corresponds to that of the belts;

[0008] The two gate piers located on the far sides of each other are fixedly connected to an arc-shaped ring plate of the same height as the gate pier. The other end of the arc-shaped ring plate is cylindrical and abuts against the surface of the interception net.

[0009] Furthermore, each of the two gate piers located on the far sides has a slot at one end. A threaded rod is rotatably connected between the inner top wall and the inner bottom wall of each slot. Each lifting frame is threadedly connected to its adjacent threaded rod, and the top ends of the two threaded rods are fixedly connected to the external motor output end.

[0010] The above method allows for adjusting the height of the interception net according to different water levels, ensuring that half of the net's height is above the water surface.

[0011] Furthermore, a linear module is installed on one side of each of the two arc-shaped ring plates, and a lifting plate that can slide up and down along the axial direction of the arc-shaped ring plate is respectively provided between one end of the two arc-shaped ring plates and one end of the belt. A sliding block is slidably connected to one side of each of the two linear modules, and a connecting rod is fixedly connected to one side of each of the two sliding blocks. The other end of each connecting rod is fixedly connected to the upper surface of its adjacent lifting plate.

[0012] The above method is used to lift the collected floating debris, making it easier for workers to handle.

[0013] Furthermore, a motor is mounted on the top of one of the lifting frames, and the output end of the motor is fixedly connected to the top of its adjacent drive shaft.

[0014] The above scheme uses a motor to drive the transmission shaft to rotate, which in turn drives the pulley and the interception net to rotate in a cycle, thereby achieving continuous collection and cleaning of floating objects. When the floating objects inside one arc-shaped ring plate are full, the floating objects on the surface of the interception net can be transferred to the other arc-shaped ring plate by reversing the belt, thus achieving dual-area alternating storage.

[0015] Furthermore, a set of drainage grooves is provided on the upper surface of both lifting plates.

[0016] The above method is used to drain the water carried by floating objects, making it easier for workers to handle them.

[0017] Furthermore, a set of water passage grooves is provided on one side of each of the two arc-shaped ring plates.

[0018] The above method allows for the collection of floating objects while facilitating water flow, reducing surface pressure, and preventing deformation.

[0019] Furthermore, a liquid level sensor is installed at one end of the gate pier located in the middle.

[0020] The above scheme uses ultrasonic pulses to transmit and receive reflected signals to monitor water level changes in real time, and then uses the linkage control system to adjust the height of the interception net.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This is a floating debris collection device at the gate of a reservoir. The intercepting net is driven by a belt to rotate in a cycle. With the scraping action of the arc-shaped ring plate, the floating debris can be automatically transferred to a centralized storage area enclosed by the arc-shaped ring plate and one end of the belt. This reduces the tedious operation of manually untying the net. It significantly improves cleaning efficiency, especially in scenarios where the reservoir spans a large area and the device is widely distributed.

[0023] The lifting frame and threaded rod are linked together, and combined with the real-time monitoring of the liquid level sensor, the height of the interception net can be dynamically adjusted to ensure that it always maintains the best interception water level, adapts to the fluctuation of the reservoir water level, and avoids collection failure due to water level that is too low or too high.

[0024] The belt can be rotated forward and backward to alternately store floating objects on both sides of the arc-shaped ring plate. When one side is full, it will automatically switch to the other side. Combined with the rapid drainage function of the lifting plate, it can operate continuously and reduce the frequency of manual intervention, thus reducing the cost of cleaning.

[0025] The interception net forms a continuous circulation structure through belt drive, avoiding the entanglement problem caused by water flow impact between traditional net sleeves; the cylindrical ends of the arc-shaped ring plate continuously scrape the net surface to prevent floating objects from adhering and leaking, while the water tank balances the water flow pressure and ensures the structural stability of the device.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 , Figure 2 and Figure 3 The floating debris collection device at the reservoir gate in this embodiment includes a set of gate piers 1. One end of each of the two outermost gate piers 1 is provided with a lifting frame 2. A drive shaft 3 is rotatably connected between the inner top wall and the inner bottom wall of each of the two lifting frames 2. Pulleys 4 are fixedly connected to the top and bottom ends of each of the two drive shafts 3. The two uppermost pulleys 4 and the two lowermost pulleys 4 are respectively connected by a belt 401.

[0036] Please see Figure 1 , Figure 2 and Figure 6 An intercepting net 5 is fixedly connected between the adjacent sides of two belts 401. The cross-section of the intercepting net 5 corresponds to that of the belts 401. The rotation of the belts 401 can drive the intercepting net 5 to rotate, thereby driving the floating objects intercepted on the surface to one side of the belts 401. A slot 7 is opened at one end of each of the two outermost gate piers 1. A threaded rod 8 is rotatably connected between the inner top wall and the inner bottom wall of each slot 7. Each lifting frame 2 is threadedly connected to its adjacent threaded rod 8. The top ends of the two threaded rods 8 are fixedly connected to the output end of an external motor. The external motor can be fixed to the gate. On the surface of the pier 1, the height of the interception net 5 can be adjusted according to different water levels to ensure that half of the height of the interception net 5 is above the water surface. A motor 13 is installed at the top of one of the lifting frames 2. The output end of the motor 13 is fixedly connected to the top of the adjacent transmission shaft 3. The motor 13 drives the transmission shaft 3 to rotate, which drives the pulley 4 and the interception net 5 to rotate in a cycle, so as to realize the continuous collection and cleaning of floating objects. When the floating objects stored inside one arc-shaped ring plate 6 are full, the floating objects on the surface of the interception net 5 can be transferred to the other arc-shaped ring plate 6 by reversing the belt 401, so as to realize the dual-area alternating storage.

[0037] Please see Figure 1 , Figure 2 and Figure 4 Two outermost gate piers 1, located far apart from each other, are each fixedly connected to an arc-shaped ring plate 6 of the same height as the gate pier 1. The other end of the arc-shaped ring plate 6 is cylindrical and abuts against the surface of the interception net 5. The arc-shaped ring plate 6 can enclose the two ends of the interception net 5, realizing the centralized storage of low-floating objects. The cylindrical end of the arc-shaped ring plate 6 can achieve the purpose of scraping the interception net 5, preventing floating objects from adhering to the filter screen surface, and achieving the purpose of cleaning the interception net 5. A set of water passage grooves 15 are opened on one side of each of the two arc-shaped ring plates 6, which can facilitate the flow of water while collecting floating objects, reduce its surface pressure, and prevent deformation.

[0038] Please see Figure 1 , Figure 2 and Figure 5 A linear module 9 is installed on one side of each of the two arc-shaped ring plates 6. A lifting plate 10 that can slide up and down along the axial direction of the arc-shaped ring plate 6 is respectively set between the two arc-shaped ring plates 6 and one end of the belt 401. A sliding block 11 is slidably connected to one side of each of the two linear modules 9. A connecting rod 12 is fixedly connected to one side of each of the two sliding blocks 11. The other end of each connecting rod 12 is fixedly connected to the upper surface of its adjacent lifting plate 10, which is used to lift the collected floating objects for easy handling by workers. A set of drainage grooves 14 is opened on the upper surface of each of the two lifting plates 10 to drain the water carried in the floating objects, making it easier for workers to handle the floating objects. A liquid level sensor 16 is installed at one end of the gate pier 1 in the middle. When the liquid level sensor 16 is non-contact, it is specifically an ultrasonic liquid level sensor 16. By emitting ultrasonic pulses and receiving reflected signals, it monitors the water level changes in real time and links the control system to adjust the height of the interception net 5.

[0039] The working principle of the above embodiment is as follows: The ultrasonic level sensor 16 located in the middle gate pier 1 continuously emits ultrasonic pulses and accurately calculates the water level height by receiving the reflected signals. The external control system drives the threaded rods 8 in the gate piers on both sides to rotate according to the real-time water level data, which drives the lifting frame 2 to move vertically along the slot 7, ensuring that the interception net 5 always keeps half of its surface above the water surface, stably intercepting floating objects. The motor 13 drives the transmission shaft 3 to rotate, which drives the two annular belts 401 to rotate synchronously through the upper and lower sets of pulleys 4. The interception net 5 fixed inside the belt 401 rotates in a cycle. The impact force of the water flow presses the floating objects only onto the net surface. When the floating objects come into contact with the interception net 5, they are blocked by the continuously rotating interception net. 5 Driven by friction, the floating objects enter the enclosed area of ​​the arc-shaped ring plate 6 for centralized storage. When the floating objects move with the interception net 5 to the cylindrical end of the arc-shaped ring plate 6, the inner wall of the ring plate is tightly attached to the net surface. The physical friction scrapes off the attached objects on the net surface, achieving self-cleaning. When the storage area on one side is saturated, the control system reverses the direction of the belt 401 to transfer the subsequent captured objects to the storage of the ring plate on the other side. Workers only need to clean at fixed points at both ends of the gate pier, avoiding the tedious process of traditional net sleeve movement and cleaning. During cleaning, the linear module 9 drives the sliding block 11 to move along the axial direction of the ring plate. Through the connecting rod 12, the lifting plate 10 is driven to slide upward from the bottom of the ring plate. The drainage groove 14 on the surface of the lifting plate 10 quickly drains the water carried by the floating objects, making it convenient for workers to transfer them.
