Description

Technical Field

[0001] The invention relates to the technical field of net cleaning, and in particular to a marine cage aquaculture cleaning device based on a combined cleaning method. Background Art

[0002] With the gradual depletion of fishery resources, marine fisheries are undergoing a major transformation from traditional fishing to aquaculture. It has become a common consensus among marine aquaculture countries around the world to shift the focus of fishery production from fishing to marine cage aquaculture. After years of development, my country's marine cage aquaculture technology has made significant progress and has become the world's largest marine aquaculture country. The water body of cage aquaculture is rich in nutrients and aquaculture waste, which provides rich nutrients for the growth of fouling organisms, thereby promoting their attachment. Because the nets are immersed in water for a long time and in direct contact with the water environment, they are very susceptible to the attachment of fouling organisms in the water, resulting in mesh blockage, decreased flow resistance of the nets, and reduced water exchange efficiency, which ultimately deteriorates the fish farming environment. If the nets are not cleaned or replaced in time, it is easy to cause fish diseases and lead to death, seriously affecting the production safety of cage aquaculture. The attachment of fouling organisms on the surface of the nets is a key factor restricting the sustainable development of marine cage aquaculture.

[0003] At present, the main method of cleaning marine cage nets in my country is still manual cleaning, which is not only inefficient, cumbersome, and labor-intensive, but also poses a great safety hazard. As marine aquaculture gradually develops into the deep sea, the traditional manual cleaning method can no longer meet the large-scale requirements of cage aquaculture. For this reason, net cleaning robots have gradually entered this field. The existing cleaning methods mainly include mechanical brush cleaning and high-pressure water jet cleaning.

[0004] Cavitation water jet cleaning technology, as a new cleaning technology that has received widespread attention in recent years, has lower energy consumption and higher cleaning efficiency than traditional high-pressure water jet cleaning, and has almost no damage to the anti-corrosion coating on the surface of the net material.

[0005] However, there are relatively few studies in the field of marine cage net cleaning robots in China, and the existing technologies generally have problems with automation level, cleaning quality and efficiency. Therefore, a marine cage aquaculture cleaning device based on a combined cleaning method is proposed to improve the cleaning efficiency and quality and promote the sustainable and healthy development of the marine aquaculture industry.

A buoyancy module 17 is installed on the top of the mounting plate 16 to increase the overall buoyancy center height of the underwater cleaning device, thereby improving stability. A fixed shaft 19 is provided at one end of the cleaning device body 1, a cleaning module 22 is installed on one end of the fixed shaft 19, and a propeller 21 is installed at the other end of the cleaning device body 1 for realizing the forward propulsion of the cleaning device body 1 so that the cleaning module 22 contacts the net.

[0029] A cable connector 10 is installed on the upper frame 9 for towing the cleaning device and providing electricity. Hooks 18 are installed at the four corners of the top of the cleaning device body 1, with a total of 4 hooks. The cleaning device can be placed into the water or recovered by the lifting device on the work boat, and the posture of the cleaning device when it is initially entered into the water can be controlled.

[0030] like Figure 4-8 As shown, the cleaning module 22 is composed of a cleaning turntable 24 and a protective shell 23. The cleaning turntable 24 is arranged inside the protective shell 23. The cleaning turntable 24 is in a "concave" shape. The concave area in the middle is used to place a brush turntable 27. There is a gap between the cleaning turntable 24 and the protective shell 23. There is a gap between the brush turntable and the cleaning turntable 24. The protective shell 23 is fixed on the outer circumference of the guide sleeve 31. The brush turntable 27 is installed in the middle of the cleaning turntable 24. The brush head 28 is installed on the brush turntable 27. The brush head 28 is used to contact the net clothes to clean the net clothes. Four nozzle installation holes 25 are evenly opened on the cleaning turntable 24. A cavitation nozzle 26 is installed on the nozzle mounting hole 25. The nozzle mounting hole 25 is connected to the diverter 29 through a high-pressure water outlet pipe 30. The diverter 29 is installed on the back of the brush turntable 27. The first high-pressure water inlet 20 pumps water into the second high-pressure water inlet 36 on the guide sleeve 31 through an external water pump, and then enters the diverter 29 through the flow channel of the guide sleeve 31. The water in the high-pressure water outlet pipe 30 is transported to the cavitation nozzle 26 through the diverter 29, and water is ejected through the cavitation nozzle 26 to impact the net clothes, and at the same time, a jet reaction force is generated, which acts on the cleaning turntable 24 to rotate it without relying on the motor.

[0032] The flow divider 29 is integrated with the cleaning turntable 24 . The flow divider 29 is connected to the flow guide sleeve 31 via a sealed bearing. The flow divider 29 rotates around the flow guide sleeve 31 .

[0033] The guide sleeve 31 is fixedly connected with a guide sleeve inner tube 37 inside. The space between the outer wall of the guide sleeve inner tube 37 and the inner wall of the guide sleeve 31 forms a flow channel, and the flow channel is connected with the diverter 29 .

[0034] Working principle: A marine cage aquaculture cleaning device based on a combined cleaning method. Before the cleaning operation, the brush material or brush type is replaced according to the situation, and the leg height is adjusted according to the seabed conditions. The cleaning device is connected, and the high-pressure pump station is connected to the first high-pressure water inlet 20 of the cleaning device through a hose. The cable is connected to the cable connector 10 of the cleaning device. The cleaning device is placed into the water through the crane on the work boat and the hook 18 on the cleaning device. The crew on the boat controls the four cables to control the posture of the cleaning device when it is initially put into the water. The longitudinal thruster 8 is started, and the cleaning device enters the water. The camera 15 and the lighting lamp 14 are started, and the second electric telescopic rod 11 and the rotary joint 12 are adjusted. A rotating motor is arranged inside the rotary joint 12 so that the crew on the boat can best observe the underwater situation. By controlling the lateral thrusters 7 and the longitudinal The propeller 8 and the propeller 21 use the camera 15 to find the position of the net that needs to be cleaned, and after adjusting the cleaning device to the best cleaning position, the motor A34 is started to drive the brush head 28 on the rotating shaft 32 to rotate. At the same time, the high-pressure pump passes the high-pressure water through the hose into the guide sleeve 31 and the high-pressure water outlet pipe 30 in sequence, and finally shoots out at high speed through the cavitation nozzle to hit the net, and at the same time generates a jet reaction force, which acts on the cleaning turntable to rotate it, forming a circular cleaning track, and producing a better cleaning effect. The motor B35 drives the propeller to start and is responsible for adjusting the target distance between the cleaning device and the net during the cleaning process. During the cleaning process, the cleaning device and the net are pressed tightly to perform the net cleaning operation. After completing one cleaning, the cleaning path is changed and the cleaning is continued. During the cleaning process, the position of the camera 15 and the lighting lamp 14 can be adjusted to judge the cleaning quality. After the cleaning operation is completed, the longitudinal propeller can be used to float to the water surface first, and then the cleaning device can be retrieved by the lifting device on the ship through the cable.

[0035] The high-pressure pump station on the work boat provides high-pressure flow, which enters the guide sleeve 31 through the water pipe and enters the cavitation nozzle through the high-pressure water outlet pipe to form a high-speed cavitation jet. At the same time, the motor A34 drives the brush head 28 to rotate to clean the net by physical friction. The "cavitation water jet cleaning-brush physical friction cleaning-cavitation water jet cleaning" is performed on the same position at one time, and the underwater net cleaning operation is realized in combination to improve the cleaning efficiency and cleaning quality.

[0036] During operation, the cleaning turntable rotates to clean the net with cavitation water jet, and the brush turntable is driven by the motor to rotate to clean the net with physical friction. The same position in a cleaning movement path is cleaned by triple cleaning: "cavitation water jet cleaning - brush physical friction cleaning - cavitation water jet cleaning".

[0037] The present invention adopts a combined cleaning method of cavitation water jet technology and a brush. Compared with high-pressure water jet cleaning, cavitation water jet cleaning has a different cleaning mechanism. High-pressure water jet cleaning uses the powerful impact force of high-speed jets to clean, which will seriously damage the surface anti-corrosion layer of the net, while cavitation water jet cleaning uses the cavitation effect generated by the collapse of a large number of cavitation bubbles in the flow beam to clean, which rarely damages the surface of the net. In terms of energy consumption, the starting pressure of the water flow of high-pressure water jet cleaning is much higher than that of cavitation water jet cleaning, and in terms of efficiency, high-pressure water jet cleaning has a lower cleaning efficiency under high energy consumption, while cavitation water jet cleaning can achieve a cleaning efficiency much higher than the former under low energy consumption.

[0038] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
