Abstract
Description
Technical Field
[0001] This utility model is a device for cleaning floating debris in river channels, belonging to the field of river cleaning equipment. Background Technology
[0002] With the acceleration of urbanization and the increase in industrial production activities, the problem of floating debris pollution in rivers is becoming increasingly serious. Floating debris such as tree branches, plastic bottles, and algae in rivers not only severely affect the aquatic landscape but also block waterways, hinder flood control, and pose threats to the ecological environment and public safety.
[0003] In the existing technology, the river floating debris cleaning device mainly consists of a salvage boat and a transmission-type salvage net. When the boat is traveling in the river, the transmission-type salvage net can salvage the floating debris and transport it into the boat. However, some small floating debris will stick to the surface of the salvage net and cannot be cleaned quickly. As the salvage net is circulated, it will be transported back into the river water, thereby reducing the efficiency of river floating debris cleaning.
[0004] In summary, this utility model provides a device for cleaning floating debris in river channels to solve the above-mentioned problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a river floating debris cleaning device to solve the problem mentioned in the background art that the floating debris adhering to the surface of the dredging net cannot be cleaned quickly, resulting in the floating debris being transported back into the river water and reducing the cleaning efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a river floating debris cleaning device, comprising a salvage vessel hull, two first mounting plates fixedly installed on one side of the hull, a first electric rotating shaft installed between opposite sides of the two first mounting plates, a first transmission roller rotatably installed between opposite sides of the two first mounting plates via the first electric rotating shaft, second mounting plates fixedly installed on the front and rear sides of the top of the hull, a second electric rotating shaft installed between opposite sides of the two second mounting plates, a second transmission roller rotatably installed between opposite sides of the two second mounting plates via the second electric rotating shaft, a belt filter screen drivingly connected between the roller surfaces of the first and second transmission rollers, the belt of the belt filter screen penetrating one side of the inner wall of the hull, and a filter hole reverse cleaning assembly fixedly installed between the two sides of the inner wall of the hull and on one side of the belt filter screen.
[0007] Furthermore, a strip-shaped opening is provided on one side of the hull of the salvage vessel to allow a belt filter to pass through, and rubber strips are fixedly adhered to both sides of the inner wall of the strip-shaped opening.
[0008] Furthermore, the conveying path of the belt filter is lower on the left and higher on the right, and the surface of the belt filter is uniformly provided with multiple filter holes.
[0009] Furthermore, the filter hole reverse cleaning assembly includes an air outlet pipe and two air pumps. The air outlet pipe runs through the space between the two sides of the inner wall of the salvage vessel. The two air pumps are fixedly installed on the front and back of the salvage vessel hull respectively by mounting brackets. Both ends of the air outlet pipe extend to the air outlet ends of the two air pumps. The air inlet ends of the two air pumps are connected to air inlet pipes. A flat pipe is installed obliquely on one side of the air outlet pipe and inside the salvage vessel hull. One end of the flat pipe is connected to a blower pipe, and one end of the blower pipe extends to one side of the belt filter screen.
[0010] Furthermore, one end of the blower tube is in contact with the surface of the belt filter, and one end of the blower tube is open.
[0011] Furthermore, the air outlet pipe is fixedly connected to the hull of the salvage vessel, and the air inlet ends of both air pumps are connected to air inlet pipes.
[0012] Furthermore, the flat tube is installed at an angle with the left side higher than the right side on the surface of the air outlet pipe, and the blower pipe is installed at an angle with the left side higher than the right side.
[0013] The beneficial effects of this utility model are:
[0014] While the belt filter screen is being used to transport and remove floating debris from the river, two air pumps inside the filter hole reverse cleaning component are activated. After the two air pumps are activated, the high-pressure airflow generated is sprayed at high speed through the flat tube and blower pipe onto the belt filter screen, which can effectively blow away the debris clogging the filter holes and remove sticky impurities such as algae adsorbed on the surface of the mesh belt. This filter hole reverse cleaning method realizes real-time automatic cleaning of the filter screen, eliminating the need for manual cleaning of the filter screen and reducing the intensity of manual labor. At the same time, the floating debris that is retrieved will not be transported back into the river water due to the belt filter screen, which effectively improves the efficiency of river floating debris removal and ensures the continuity and stability of the cleaning work.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] Please see Figure 1-4This utility model provides a technical solution: a river floating debris cleaning device, including a salvage vessel hull 1. Two first mounting plates 2 are fixedly installed on one side of the salvage vessel hull 1. A first electric rotating shaft 3 is installed between the opposite sides of the two first mounting plates 2. A first transmission roller 4 is rotatably installed between the opposite sides of the two first mounting plates 2 via the first electric rotating shaft 3. Second mounting plates 5 are fixedly installed on the front and rear sides of the top of the salvage vessel hull 1. A second electric rotating shaft 6 is installed between the opposite sides of the two second mounting plates 5. A second transmission roller 7 is rotatably installed between the opposite sides of the two second mounting plates 5 via the second electric rotating shaft 6. A belt filter screen 8 is connected between the roller surfaces of the first transmission roller 4 and the second transmission roller 7. The belt of the belt filter screen 8 passes through one side of the inner wall of the salvage vessel hull 1. A filter hole reverse cleaning component 9 is fixedly installed between the two sides of the inner wall of the salvage vessel hull 1 and on one side of the belt filter screen 8. The first electric rotating shaft 3 and the second electric rotating shaft 6 integrate a motor and a transmission mechanism. After the motor is powered on, current flows through... The winding generates a magnetic field, and under the action of electromagnetic force, the motor rotor begins to rotate. The rotational power is then transmitted to the rotating shaft through the transmission mechanism, thereby driving the rotating shaft to rotate. By controlling the magnitude, direction, and frequency of the input current, the speed and direction of the electric rotating shaft can be precisely adjusted. The first transmission roller 4 can rotate stably under the drive of the first electric rotating shaft 3. Through the rotation of the first transmission roller 4 and the second transmission roller 7, the belt filter screen 8 is driven to circulate, thereby realizing the continuous retrieval of floating objects in the river. A strip-shaped opening is provided on one side of the hull 1 of the retrieval vessel to accommodate the belt filter screen 8. Rubber strips are fixedly adhered to both sides of the inner wall of the strip-shaped opening. The rubber strips are made of EPDM rubber, which has good elasticity and wear resistance. The rubber strips are tightly attached to the surface of the belt filter screen 8, which can not only ensure that the belt filter screen 8 passes smoothly, but also effectively prevent river water from seeping into the interior of the hull 1 of the retrieval vessel from the strip-shaped opening, affecting the normal operation of the equipment. The conveying path of the belt filter screen 8 is lower on the left and higher on the right. Multiple filter holes are evenly opened on the surface of the belt filter screen 8.
[0023] Please see Figure 2-4The filter hole reverse cleaning assembly 9 includes an air outlet pipe 91 and two air pumps 92. The air outlet pipe 91 runs through the inner wall of the salvage vessel hull 1 between the two sides. The two air pumps 92 are fixedly installed on the front and back of the salvage vessel hull 1 respectively by mounting brackets. Both ends of the air outlet pipe 91 extend to the air outlet ends of the two air pumps 92 and are connected by flanges to ensure reliable sealing. The air inlet ends of the two air pumps 92 are connected to air inlet pipes 93. A flat pipe 94 is installed obliquely on one side of the air outlet pipe 91 and inside the salvage vessel hull 1. One end of the flat tube 94 is connected to a blower pipe 95, and one end of the blower pipe 95 extends to one side of the belt filter screen 8. One end of the blower pipe 95 is in contact with the surface of the belt filter screen 8 and is open. The air outlet pipe 91 is fixedly connected to the hull 1 of the salvage vessel. The air inlet ends of the two air pumps 92 are connected to air inlet pipes 93. The air outlet pipe 91 runs through the inner wall of the salvage vessel hull 1 on both sides. It is made of Q235B seamless steel pipe with an outer diameter of 108mm and a wall thickness of 4mm, and has good pressure resistance. The system is corrosion-resistant and can withstand a working pressure of 0.8 MPa. Two air pumps 92 are fixedly installed on the front and back of the salvage vessel hull 1 via mounting brackets. The mounting brackets are welded from angle steel and hot-dip galvanized, providing a corrosion resistance of ≥15 years. The air pumps 92 are Roots blowers, capable of providing stable high-pressure airflow. A flat pipe 94 is installed at an angle, higher on the left and lower on the right, on the surface of the outlet pipe 91. A blower pipe 95 is also installed at an angle, higher on the left and lower on the right. When the air pumps 92 are working, air enters through the inlet pipe 93. The air pump 92 pressurizes the air and then passes it through the air outlet pipe 91 and the flat pipe 94 into the air blowing pipe 95. Finally, the air blows the air from the opening end of the air blowing pipe 95 into the belt filter screen 8 in the form of high-speed airflow. This reverses the cleaning of the debris blocking the filter holes, effectively preventing the belt filter screen 8 from clogging and ensuring the continuous and efficient operation of the cleaning device. The airflow velocity at the outlet of the air blowing pipe 95 is ≥30m / s, which can generate sufficient impact force to blow off the debris blocking the filter holes and the algae and other impurities adsorbed on the outside of the belt filter screen 8.
[0024] Specific implementation method: The operator drives the salvage vessel hull 1 to the river area to be cleaned, starts the first electric rotating shaft 3 and the second electric rotating shaft 6, drives the first transmission roller 4 and the second transmission roller 7 to rotate synchronously. The two transmission rollers drive the belt filter screen 8 to rotate in a cycle. The filter screen is arranged with the left side lower and the right side higher. When the hull moves forward slowly, floating objects such as tree branches and algae in the river are intercepted on the net surface and transported upward with the net belt. As the net belt moves upward, the floating objects slide into the collection tank inside the hull under the action of gravity and vibration.
[0025] The salvage vessel hull 1 has a strip-shaped opening on one side for the belt filter 8 to pass through. Rubber strips are fixedly adhered to both sides of the inner wall of the strip-shaped opening. The rubber strips are made of EPDM rubber, which has good elasticity and wear resistance. The rubber strips are tightly attached to the surface of the belt filter 8, which can not only ensure that the belt filter 8 passes through smoothly, but also effectively prevent river water from seeping into the interior of the salvage vessel hull 1 from the strip-shaped opening and affecting the normal operation of the equipment.
[0026] At the same time, two air pumps 92 are started. The two air pumps 92 draw in external air from the air inlet pipe 93 and deliver it to the inside of the flat pipe 94 through the air outlet pipe 91. After the high-pressure airflow is distributed through the flat pipe 94, it is ejected at high speed from the opening of the blow pipe 95, so that the airflow can effectively blow away the debris blocking the filter holes and remove the sticky impurities such as algae adsorbed on the surface of the mesh belt.
[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
