Description

Technical Field

[0001] The invention belongs to the technical field of intercepting floating objects on water surfaces, and in particular relates to a floating intercepting raft with an automatic discharging function. Background Art

[0002] In environments like rivers and dams, floating debris often lingers on the water surface, impacting both the river and the water quality. This is especially true after the flood season, when large floating debris is more common. Intercepting and recovering floating debris is essential for environmental remediation. Floating barriers rely on the buoyancy of their floats to keep them afloat, forming a barrier. When floating debris in the current approaches the barrier, it is blocked by the trash racks and prevented from continuing with the current. Furthermore, the barrier effect of the barrier causes floating debris to gradually accumulate in front of the barrier, facilitating centralized recovery and removal.

[0003] Currently, the commonly used water garbage intercepting rafts use steel wire ropes, iron chains, nylon ropes and other connectors with high strength and flexibility to connect several cylindrical floating bodies in series, build fixed piles and heavy anchors on the shore, and use ropes or chains to connect them to the intercepting rafts to ensure that the intercepting rafts can float stably on the water surface to perform interception work and prevent the intercepting rafts from drifting with the water flow or wind and waves.

[0004] The fixed piles at both ends of the floating raft cannot withstand overload. When the tension borne by the fixed piles at both ends is greater than the allowable load, the fixed piles will fall off, causing unforeseen accidents. Especially when the water flow speed is high, the fixed piles will bear greater tension, and the floating raft will be greatly affected. Summary of the Invention

[0005] The present invention aims to provide a drift arresting raft with an automatic collapse function to solve the problem in the prior art that when the drift arresting raft is overloaded, the fixed piles at both ends thereof are easily fallen off due to the excessive tension.

[0006] A drift-blocking row with an automatic collapse function in this solution includes several floating bodies, which are connected by a connector. The connector includes a first mounting seat and a second mounting seat. The first mounting seat is provided with two parallel first connecting plates, and the second mounting seat is provided with a second connecting plate. The first connecting plate and the second connecting plate are both provided with connecting holes; the first mounting seat is connected to one end of the connector, and the second mounting seat is connected to the other end of the connector. When multiple connectors are connected, the second connecting plate is inserted between the two first connecting plates to make the centers of the connecting holes coaxial. The first connecting plate and the second connecting plate between the two floating bodies in the middle of the entire drift-blocking row are connected after a shear pin is inserted into the three connecting holes; the first connecting plates and the second connecting plates in the remaining parts are connected by inserting a pin shaft into the three connecting holes.

[0007] The working principle of this solution is as follows: during the operation of the drift arresting raft, floating objects will gather in front of the raft, and the middle part of the raft is not only the area where the floating objects are relatively concentrated, but also the place where the impact force is concentrated. When the water flow carries floating objects to impact the raft, due to the constraints of the fixed piles at both ends, the middle part becomes the key area for force transmission, and the impact force it bears far exceeds that of the two ends. If the shear pins are set at both ends, when encountering extreme water flow or a large number of floating objects, the tension on the fixed piles at both ends will increase dramatically, and they will easily fall off, causing the raft to drift out of control, and the huge impact force accumulated in the middle part cannot be released in time, which may cause damage to other parts of the raft or even collapse of the entire structure. The shear pin is set in the middle of the drift arresting row. When the drift arresting row is overloaded, the shear pin breaks and the drift arresting row is disconnected from the middle. On the one hand, it can disperse the overall impact force, avoid excessive tension on the fixed piles at both ends, and ensure the safety of key fixed structures; on the other hand, the drift arresting row forms two relatively regular parts after self-collapse, and the shape is stable. It will not cause excessive shape changes and additional stress due to disconnection, which is easy to recover, reduces damage to the remaining structure, and provides convenience for subsequent reassembly and use. At the same time, it makes the self-collapse process more controllable, reduces accidental risks, and effectively protects the main structure of the drift arresting row.

[0008] The beneficial technical effect of this solution is that, compared to traditional float arresters, this design uses shear pins in the middle of the float arrester. When the float arrester is overloaded, such as when the water velocity is too high or there are too many floating objects, the shear pins will break first, causing the float arrester to break in the middle, rather than the fixed piles at both ends falling off due to excessive tension. This self-collapse function avoids unforeseen accidents caused by the falling of fixed piles, ensures the safety of the float arrester and the surrounding environment, and facilitates subsequent repairs and adjustments.

[0009] Furthermore, the float arrester barge also includes two winches, each installed on either side of the river. The wire ropes or chains of the two winches are connected to two connectors in the middle of the barge. When the barge is operating normally, the winches are in standby mode. If the barge collapses due to overload, i.e., if the shear pins in the middle break, the winches can retract and extend the wire ropes or chains to recover and adjust the position of the two broken barges.

[0010] The winch enhances control over the raft. If the raft breaks, it can be promptly retrieved to shore, preventing it from drifting away with the current and causing secondary damage or loss. This also facilitates subsequent repair and reassembly, improving safety and operability.

[0011] Furthermore, it also includes a control system, the control system includes a signal receiver and a micro sensor, the output end of the signal receiver is electrically connected to a driver, the output end of the driver is electrically connected to the power mechanism of the hoist, and the micro sensor is arranged in the shear pin; When the shear pin breaks due to overload, the microsensor sends a signal to the signal receiver. The signal receiver then sends a signal to the driver, which in turn activates the power mechanism and causes the winch to retract the wire rope or chain, thereby pulling the two broken rafts toward shore. This solution enables automated monitoring and processing of raft collapses. Without the need for manual real-time monitoring, the system can react quickly the moment the shear pin breaks, activating the winch to recover the raft. This significantly improves response speed and processing efficiency, reduces the likelihood of accidents caused by untimely manual monitoring, and further enhances the safety and intelligence of the raft.

[0012] Furthermore, the control system also includes an external device for receiving signals from the microsensors. This solution allows managers to remotely monitor the operating status of the drift arrester. Through this external device, managers can monitor the drift arrester's status at any time, without having to visit the site. This facilitates timely decision-making and scheduling, improves management efficiency, and facilitates unified management and maintenance of the drift arrester.

[0013] Furthermore, the external device is selected from a smartphone or a computer. Using widely available smart devices as external devices lowers the threshold for using the system and reduces costs, making it easier for managers to receive status information on the drift arrester anytime and anywhere, making remote monitoring more convenient and accessible, and making the management of the drift arrester more flexible and efficient.

[0014] Furthermore, the float is a box-like structure with internally connected reinforcing ribs. While the box-like structure inherently provides strength and stability, the internal reinforcing ribs further enhance the structural strength of the float. During operation, the float relies on its own buoyancy to remain afloat, withstanding the impact of currents and floating objects. The reinforcing ribs serve to disperse stress and enhance structural stability.

[0015] Compared with traditional floating bodies, floating bodies with box-type structures and internal reinforcing ribs have higher strength and impact resistance, can better adapt to complex water flow environments and withstand the impact of floating objects, extend the service life of the floating body, ensure the stability and reliability of the overall structure of the drift-arresting raft, and improve the working performance of the drift-arresting raft.

[0016] Furthermore, mounting holes are provided at both ends of the float, through which the two ends of the reinforcing ribs pass to connect to the first and second mounting seats. In this embodiment, the reinforcing ribs not only enhance the strength of the float itself but also tightly connect the float and the connector, forming a stable overall structure. When the drift-arresting raft is subjected to forces from the water flow and floating objects, the forces are effectively transferred between the float and the connector via the reinforcing ribs.

[0017] This connection method between the reinforcing ribs, the floating body and the connector further improves the connection strength and stability of the overall structure of the drift arresting raft, makes the collaborative working ability between the various components of the drift arresting raft stronger, and makes it less likely for components to fall off or connections to loosen when subjected to large external forces, thereby ensuring the normal operation and interception effect of the drift arresting raft.

[0018] Furthermore, the reinforcing ribs are tubular, which enhances the strength of the floating body while avoiding excessive increase in overall weight.

[0019] Furthermore, the first and second mounting plates are both seamlessly welded to the floating body, and the reinforcing ribs are seamlessly welded to the mounting holes. This solution improves the reliability and strength of the connections between the various components of the drift arrester raft, enhancing the stability and durability of the raft's overall structure. This reduces the probability of failures due to connection problems, lowers maintenance costs, and enables the raft to operate stably and long-term in harsh environments, effectively intercepting floating objects.

[0020] Furthermore, the interior corners of the float are connected using angle steel. Angle steel, with its high strength and rigidity, enhances the structural strength of these corners, dissipates stress, and strengthens these relatively weak corners. This allows the float to better maintain its shape and structural integrity in complex water flow environments, improves its impact resistance, extends its service life, and ensures the overall performance of the float interceptor.

DETAILED DESCRIPTION

[0022] The following is further described in detail through specific implementation methods: The reference numerals in the drawings of the specification include: floating body 1, second mounting seat 2, second connecting plate 3, connecting hole 4, first connecting plate 5, pin 6, shear pin 7, winch 8, and wire rope 9.

[0023] The embodiment is basically as shown in the attached Figure 1 、 Figure 2 、 Figure 3 The following figure shows a floating raft with automatic collapse function, which includes several rectangular box-shaped floating bodies 1, connected at the corners by angle steel. The floating bodies 1 have mounting holes at both ends, and tubular reinforcement ribs are welded between the two mounting holes.

[0024] The two ends of several floating bodies 1 in the length direction are connected by a connector, which includes a first mounting seat and a second mounting seat 2. The first mounting seat is provided with two parallel first connecting plates 5, and the second mounting seat 2 is provided with a second connecting plate 3. The first connecting plate 5 and the second connecting plate 3 are both provided with connecting holes 4; the first mounting seat is connected to one end of the connector, and the second mounting seat 2 is connected to the other end of the connector. When multiple connectors are connected, the second connecting plate 3 is inserted between the two first connecting plates 5 so that the centers of the connecting holes 4 are coaxial. The first connecting plate 5 and the second connecting plate 3 between the two floating bodies 1 in the middle of the entire drift-blocking row are connected after the shear pin 7 is inserted into the three connecting holes 4; the first connecting plates 5 and the second connecting plates 3 in the remaining parts are connected by the pin 6 axis inserted into the three connecting holes 4.

[0025] After passing through the mounting holes, both ends of the reinforcement ribs are welded to the first mounting seat and the second mounting seat 2. The first mounting plate and the second mounting plate are seamlessly connected to the floating body 1 by welding, and the reinforcement ribs are seamlessly connected to the mounting holes by welding.

[0026] The floating arrester also includes a control system and two winches 8, which are installed on both sides of the river. The steel wire ropes 9 or chains of the two winches 8 are respectively connected to two connectors located in the middle of the floating arrester. The control system includes a signal receiver and a micro sensor. The output end of the signal receiver is electrically connected to a driver, and the output end of the driver is electrically connected to the power mechanism of the winch 8. The micro sensor is set in the shear pin 7. When the shear pin 7 breaks due to overload, the micro sensor sends a signal to the signal receiver. When the signal receiver receives the signal, it sends a signal to the driver. After the driver receives the signal, the power mechanism starts to operate, and the winch 8 retracts the steel wire rope 9 or chain, thereby pulling the two broken floating arresters back to the shore.

[0027] As an optimization, the control system further includes an external device for receiving the signal sent by the micro sensor. The external device is selected from a smart phone or a computer.

[0028] This self-collapsing floating barrier is designed to solve the problem of existing floating barrier rafts being prone to falling off due to overload. Its working principle is as follows: Under normal circumstances, the drift-arresting raft is connected to the middle connector through the winches 8 on both sides of the river to maintain a stable floating state. When encountering extreme water flow or a large number of floating objects, the middle part of the drift-arresting raft is overloaded, and the shear pin 7 breaks due to the force exceeding the threshold. At this time, the micro sensor set in the shear pin 7 immediately sends a signal to the signal receiver. After receiving the signal, the signal receiver transmits the instruction to the driver, and the driver drives the power mechanism of the winch 8 to operate, so that the winch 8 retracts the wire rope 9 or chain and pulls the two disconnected sections of the drift-arresting raft to the shore. At the same time, the external equipment in the control system (smartphone or computer) can receive the micro sensor signal in real time, which is convenient for management personnel to remotely monitor the status of the drift-arresting raft, make timely decisions and dispatch, and ensure that when problems occur with the drift-arresting raft, they can respond quickly to avoid accidents caused by the falling of fixed piles, and ensure the safety of the drift-arresting raft and the surrounding environment.
