[0002] The main cause of flood disasters in my country is flash floods caused by the increase in water volume and rising water levels in rivers and lakes due to heavy rainfall. With the frequent occurrence of flood disasters, the construction of flood control and drainage projects has become an important part of water conservancy engineering work.

[0003] In recent years, with the outstanding performance of screen cleaners in sewage treatment, screen cleaners have been widely introduced in the construction of flood control and drainage projects. They can stably intercept and remove solid waste in water flows under various environments, reducing the need for manual operation. However, after a flash flood, the flood water continuously washes away the terrain along the way. When the flood water flows to the flood control and drainage facilities, it is often mixed with a large amount of mud, sand, stones, and debris. Among them, the deposition of mud and sand will raise the water level, increasing the pressure of flood control and drainage; the stones and debris, pushed by the flood water, will impact the component structures of the water conservancy facilities, easily causing damage and blockage of the facilities. However, the screen cannot filter large-volume materials such as stones and mud, and is prone to clogging, which requires shutdown for cleaning, affecting the continuous operation of the equipment.

[0048] In order to solve the problem of difficulty in clearing mud, sand and stones during flood control and drainage, the present application provides a river flood control and drainage system, the specific embodiments of which are as follows:

[0049] In one embodiment, see Figures 1 to 4 , the present application provides a river flood control and drainage system, comprising a pump station 1, a screen dirt remover 2, a sand pump 3, a first auger loosening machine 4 and a crushing assembly 5;

[0050] The crushing assembly 5, the first auger loosening machine 4, the screen cleaner 2, the sand pump 3 and the pump station 1 are arranged in sequence along the water flow direction of the river channel 8; the sand pump 3 and the first auger loosening machine 4 are both arranged close to the riverbed, and the sand pump 3 is located between the gate 11 of the pump station 1 and the screen of the screen cleaner 2; the first auger loosening machine 4 is located on the side of the screen cleaner 2 away from the sand pump 3;

[0051] The crushing assembly 5 includes a first wolf tooth roller 51 and a second wolf tooth roller 52 , and the rotation axes of the first wolf tooth roller 51 and the second wolf tooth roller 52 are both perpendicular to the riverbed.

[0052] The grating cleaner 2 is a specialized water treatment device that automatically and continuously intercepts and removes various forms of debris from fluids. Its operating principle is a rotating grating chain composed of unique rake teeth. Driven by a motor reducer, the rake chain rotates against the direction of the water flow. When the rake chain reaches the upper portion of the device, the guide of the sheaves and curved rails creates a relative self-cleaning motion between each set of rake teeth. Most solid matter falls by gravity and is then transported and collected by a conveyor belt.

[0053] In this embodiment, the auger loosening machine is mainly composed of a drive motor and a rotating shaft. The rotating shaft is connected to the output shaft of the drive motor and is provided with spiral blades. When the drive motor drives the rotating shaft to rotate, the spiral blades rotate and push the fluid. Under the action of the normal force of the blades and the thrust generated by the acceleration of the fluid, the fluid in the environment around the rotating shaft can be stirred and the solid material can be loosened.

[0054] In this embodiment, the sand pump 3 works based on the centrifugal force. The centrifugal force is generated by the rotation of the impeller to transport liquid or sediment and other materials from the suction end to the discharge end, which can effectively process liquid containing solid particles.

[0055] In this embodiment, due to the obstruction of the screen of the screen cleaner 2 and the gate 11 of the pump station 1, the silt in the flood is more likely to settle on the riverbed in front of the screen cleaner 2 and the pump station 1, thereby raising the water level. Therefore, the first auger loosening machine 4 is arranged close to the riverbed, and the surface riverbed soil and water flow are stirred by the rotation of the auger blades to prevent the silt in the flood from settling in front of the screen cleaner 2; and the sand pump 3 is arranged close to the riverbed so that the silt blocked by the gate 11 of the pump station 1 can be cleaned in time before it is deposited and formed on the riverbed.

[0056] In this embodiment, the first wolf tooth roller 51 and the second wolf tooth roller 52 can be driven by a motor, hydraulically driven or manually assisted to perform cyclic mechanical rotation; the roller surfaces of the first wolf tooth roller 51 and the second wolf tooth roller 52 have a number of rigid structure tooth particles, and the tooth particles of the first wolf tooth roller 51 and the second wolf tooth roller 52 are staggered. When stones or debris in the flood pass through the first wolf tooth roller 51 and the second wolf tooth roller 52, they will be bitten by the tooth particles on the first wolf tooth roller 51 and the second wolf tooth roller 52 and broken into small fragments.

[0057] Therefore, when the system is performing flood control and drainage work, the flood will first pass through the crushing component 5, and the stones and debris mixed in the flood will be pushed by the water flow to the gap between the first wolf tooth roller 51 and the second wolf tooth roller 52, and will be squeezed and crushed into small-sized fragments as the first wolf tooth roller 51 and the second wolf tooth roller 52 rotate relative to each other, while the mud and sand in the flood will directly pass through the crushing component 5 with the water flow; the flood that passes through the crushing component 5 flows to the screen cleaner 2, and the stones and debris that are crushed into small-sized fragments and part of the mud and sand will be directly removed by the screen The sewage machine 2 cleans, and the other part of the silt either passes through the screen with the water flow or is blocked by the screen and deposited; among them, the silt deposited by the screen will be stirred by the first auger loosening machine 4 and will be swept by the water flow fluctuation caused by the rotation of the spiral blades and flow to the screen sewage machine 2 again; the flood that passes through the screen sewage machine 2 is eventually blocked by the gate 11 of the pump station 1, and the silt in the flood begins to deposit on the riverbed. At this time, the sand pump 3 is used to suck the silt into the riverbed to effectively remove the silt; finally, the pump station 1 can be opened and the water can be released in time according to the water level of the impoundment.

[0058] In one embodiment, see Figures 2 to 5 , the crushing assembly 5 further includes a roller seat 53;

[0059] The roller seat 53 is provided with a sliding mechanism fixedly connected to the rotating shaft of the second wolf tooth roller 52 , so that the second wolf tooth roller 52 can slide relatively in the roller seat 53 ; the rotating shaft of the first wolf tooth roller 51 is fixedly connected to the roller seat 53 .

[0060] In this embodiment, the roller seat 53 is used to mount and secure the first and second cam rollers 51, 52, and also provides a work platform for operators to inspect and maintain the first and second cam rollers 51, 52. Furthermore, a sliding mechanism is provided to adjust the spacing between the first and second cam rollers 51, 52, thereby adaptively adjusting the degree of crushing of rocks and debris by the crushing assembly 5 based on the solid debris processing capacity of the screen cleaner 2. The sliding mechanism can be a linear track with a locking mechanism, a mechanical rack structure, or an electric slide.

[0061] Further, based on the aforementioned embodiment, the first wolf tooth roller 51 rotates clockwise along its rotation axis, and the second wolf tooth roller 52 rotates counterclockwise along its rotation axis, and the rotation axes of the first wolf tooth roller 51 and the second wolf tooth roller 52 both have a one-way rotation limiting mechanism.

[0062] In this embodiment, the first wolf-tooth roller 51 rotates clockwise along its rotation axis, while the second wolf-tooth roller 52 rotates counterclockwise along its rotation axis. This ensures that the first and second wolf-tooth rollers 51, 52 pull rocks and debris they come into contact with to the center of the river channel 8 for crushing, rather than pulling them to the sides of the river channel 8 and causing blockage. Furthermore, the provision of a one-way rotation limiter ensures that the first and second wolf-tooth rollers 51, 52 rotate in a predetermined direction, thus avoiding the impact caused by uneven thrust of the water flow on different positions of the rollers.

[0063] In one embodiment, the crushing assembly 5 further includes at least one auxiliary motor 54 and a pressure sensor;

[0064] The output shaft of the auxiliary motor 54 is fixedly connected to the rotating shaft of the first wolf tooth roller 51 and / or the rotating shaft of the second wolf tooth roller 52 ; the pressure sensor is electrically connected to the auxiliary motor 54 .

[0065] In this embodiment, when the crushing assembly 5 needs to work, the auxiliary motor 54 can provide a pre-rotation driving force for the first and / or second rollers 51, 52. When the first and / or second rollers 51, 52 can maintain a cyclic rotation state under the thrust of the water flow, the auxiliary motor 54 is disconnected from the power supply. When encountering stones or debris that are too hard to be crushed by hydraulic drive, the stones or debris will be stuck between the first and second rollers 51, 52, and the reaction force generated by the squeeze contact will be transmitted to the pressure sensor through the roller. When the pressure sensor detects an abnormal load, it will restart the auxiliary motor 54, increase the torque of the first and / or second rollers 51, 52, and crush the stones or debris with pressure. When the load returns to the initial range, the auxiliary motor 54 is turned off again. In this way, while ensuring the crushing capacity of the crushing assembly 5, the working time and output power of the motor can be reduced, saving energy.

[0066] In one embodiment, see Figures 6 to 8 The river flood control and drainage system also includes a backflow seat 6, which is arranged near the crushing assembly 5 on the side away from the pump station 1, and there are two backflow seats 6 symmetrically arranged along the river banks on both sides;

[0067] The end surface of the backflow seat 6 facing away from the crushing assembly 5 is an inclined surface, which is defined as the water-facing surface; the water-facing surface extends from the two river banks away from the crushing assembly 5 to the center of the river channel 8 near the first wolf tooth roller 51 or the second wolf tooth roller 52. The backflow seat 6 ensures that rocks and debris in the flood are guided to the center of the river channel 8 for crushing by the crushing assembly 5, preventing some rocks and debris from flowing with the water into the dead corners near the river banks on both sides of the crushing assembly 5, causing blockage and affecting the continuous operation of the flood control and drainage system.

[0068] Furthermore, based on the aforementioned embodiment, the backflow seat 6 further includes an impact plate 61 , and the impact plate 61 is fixedly connected to the water-facing surface via an elastic buffer structure.

[0069] In this embodiment, a number of protrusions are provided on the impact plate 61, and the protrusions are made of high-strength and wear-resistant metal materials. When stones and debris in the flood abut against the impact plate 61, the protrusions will exert a reaction force on the stones and debris, thereby protecting the backflow seat 6 and also having the effect of preliminarily crushing some of the stones and debris in the flood; the impact plate 61 is fixedly connected to the water-facing surface through an elastic buffer structure, which can buffer the impact force generated by the flood water flow and the stones and debris in the flood, and avoid the impact force being directly transmitted to the backflow seat 6; specifically, the elastic buffer structure can be a spring structure, a hydraulic rod structure, a cylinder structure, etc.

[0070] In one embodiment, the river flood control and drainage system further includes a comprehensive monitoring component.

[0071] In this embodiment, the integrated monitoring component includes a water level monitoring element and a flow rate sensing element; the water level monitoring element is fixedly connected to the outer end face of the backflow seat 6, and the flow rate sensing element is arranged in an elastic buffer structure. By monitoring the flood flow rate and water level, the pump station 1 can be controlled in time to perform drainage regulation. Among them, the water level monitoring element is arranged on the outer end face of the backflow seat 6, which can directly contact the water flow, and the current flood water level can be conveniently obtained according to the depth of immersion of the backflow seat 6; the flow rate sensing element is arranged in the elastic buffer structure, and the current flood flow rate can be obtained according to the impact force exerted by the water flow on the impact plate 61, thereby estimating the water flow rate.

[0072] In one embodiment, the integrated monitoring assembly also includes a biosensor element for monitoring organic biological reactions in the water flowing toward the backflow seat 6. This biosensor element is used to monitor organic biological reactions in the water flow, determine whether there are people or living animals who have lost water, and then control the flood control and drainage system to shut down relevant components to prevent secondary harm to people or animals who have lost water. Specifically, the biosensor element can be implemented using infrared temperature measurement equipment, using infrared radiation from organisms to convert thermal energy into electrical signals that are fed back to processing equipment or generate alarms.

[0073] In one embodiment, see Figure 7 and Figure 8 The river flood control and drainage system also includes a second auger loosening machine 7, which is installed near the riverbed and between the screen cleaner 2 and the pump station 1. The second auger loosening machine 7 can assist the sand pump 3 in removing sediment, thereby preventing the sand pump 3 from failing to keep up with the sediment deposition rate due to excessive sediment content in the flood, which would cause sediment deposition and raise the water level.

[0074] In one embodiment, based on the aforementioned embodiments, the pumping station 1 is provided with a control room equipped with a processor;

[0075] The grid cleaner 2, the sand pump 3, the first auger loosening machine 4, the auxiliary motor 54, the pressure sensor, the integrated monitoring component and the second auger loosening machine 7 are all electrically connected to the processor.

[0076] In summary, when the river flood control and drainage system of the present application is in actual operation, the staff of the pump station 1 first observes the incoming flood and gradually starts the auxiliary motor 54, the screen cleaner 2, the first auger loosener 4, the sand pump 3 and the second auger loosener 7 in the control room, so that each component starts to operate. The flood will pass through the various components of the flood control and drainage system in turn and will eventually be intercepted by the gate 11 of the pump station 1. The stones, mud and debris therein are gradually removed by the crushing component 5, the screen cleaner 2 and the sand pump 3; and according to the water level and flow information obtained by the water level monitoring element and the flow rate sensing element of the comprehensive monitoring component, when the real-time water storage situation is close to the maximum storage capacity of the pump station 1, the gate 11 of the pump station 1 is opened for drainage regulation; and when the biological sensing element of the comprehensive monitoring component recognizes a life reaction, the processor will control the auxiliary motor 54, the screen cleaner 2, the first auger loosener 4, the sand pump 3 and the second auger loosener 7 to stop urgently to avoid secondary harm to the people or animals who have lost water.

[0077] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.

[0078] The above are only optional embodiments of the present application and are not intended to limit the present application.
