Description

Technical Field

[0001] This invention relates to the field of underwater cleaning devices, specifically a garbage recycling robot. Background Technology

[0002] The prior art, disclosed in patent number CN116349639B, describes a robot for detecting and cleaning diseased and dead fish in deep-sea cages. This robot relates to deep-sea aquaculture and underwater robotic operations. It features a sliding ramp on both sides of the collection tank's entrance and a propeller at the tank's drain outlet. The propeller's drain outlet and the diseased / dead fish collection outlet are diagonally distributed longitudinally. When the propeller drives the water out of the collection tank, creating negative pressure, external water is drawn into the diseased / dead fish collection outlet, pulling diseased and dead fish from the bottom of the cage into the outlet and causing them to leap up along the sliding ramp before falling into the sides of the collection tank. A waterproof pan-tilt camera and a waterproof binocular camera monitor the collection operation in real time. This device effectively counteracts the thrust generated during drainage, significantly improving the stability of the underwater robot's movement while minimizing the impact on fish inhabiting the bottom of the cages, thus minimizing disruption to normal aquaculture during the harvesting of diseased and dead fish.

[0003] However, the device still has some obvious drawbacks in use: although it can clean underwater garbage and dead fish, it uses a propeller propulsion method, which causes underwater currents, and the garbage may exist at different depths on the bottom of the water. The robot can only clean up the garbage that exists on the bottom of the water, so its cleaning effect is limited. Summary of the Invention

[0004] The purpose of this invention is to provide a waste recycling robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A garbage recycling robot includes:

[0007] The vehicle body is equipped with a power unit, a fishing unit, an aeration unit and a visual image acquisition unit, and the interior of the vehicle body is also equipped with a garbage collection compartment.

[0008] The catching unit includes a catching port located at the front of the vehicle body in the direction of travel. The catching port is connected to the garbage collection compartment. The garbage collection compartment is also provided with an internal and external through-hole drainage outlet on the side of the vehicle body away from the catching port. The sinking garbage is caught by installing electric drainage paddles at the through-hole.

[0009] The fishing unit further includes a fishing umbrella storage cabin arranged above the vehicle body. The fishing umbrella storage cabin is spaced from the garbage collection cabin by a partition. A motorized opening and closing upper hatch is slidably arranged above the fishing umbrella storage cabin. A towing rope is wound and unwound in the fishing umbrella storage cabin through a winding mechanism. One end of the towing rope away from the winding mechanism is connected to an aeration blocking net cover.

[0010] The aeration blocking net cover consists of an annular floating airbag and an annular blocking net. The annular blocking net is connected below the annular floating airbag. The cross-section of the annular blocking net is in an "L" shape with the open end facing the inside of the annular floating airbag. The aeration blocking net cover is stored in the fishing umbrella storage cabin in the exhaust state and floats on the water surface of the net cage during the aeration fishing process. The annular floating airbag is connected to a compressed air pump arranged inside the vehicle body through a hollow pipeline. The compressed air pump supplies air to the annular floating airbag to make it inflate and float. The compressed air pump is fixedly installed in the fishing umbrella storage cabin.

[0011] The aeration unit includes a pair of aeration rods telescopically arranged at the bottom of the vehicle body. The pair of aeration rods are parallelly installed at the bottom of the lifting turntable. The lifting turntable makes the aeration rods be stored or protrude from the lower plane of the vehicle body through lifting movement. In the protruding state, the lifting turntable drives the pair of aeration rods to perform rotational movement. The aeration rods are connected to a floating pump machine arranged in a floating manner through a hollow pipeline. The floating pump machine pumps the gas on the water surface through the aeration rods and pushes the garbage at the bottom of the net cage to float, thereby establishing a bubble circulation flow that gathers and flows upward from the four sides of the bottom of the net cage. The fluid drives the garbage to float and disperse around and sink downward after reaching the water surface. At this time, the aeration blocking net cover is used to fish and collect the settled garbage.

[0012] Preferably, a front hatch is also arranged at the fishing port in a hinged and flip-up manner. The opening and closing of the front hatch are used to open and close the fishing port. A deflector is also fixedly installed on the vehicle body at the front end of the fishing port.

[0013] Preferably, an arc-shaped blocking plate is fixedly installed on one side of the vehicle body inside the fishing port. A sealed cabin is also arranged on the other side of the vehicle body away from the fishing port. A battery and a main board are installed in the sealed cabin.

[0014] Preferably, a blocking net cover is also fixedly installed on the inner side of the electric drainage paddle in the garbage collection cabin.

[0015] Preferably, the power unit includes a crawler motor, crawler wheels and a traveling crawler. The crawler motors are fixedly installed at the four corners of the vehicle body. The crawler wheels are fixedly installed on the vehicle body in a fixed-axis rotation manner and are coaxially fixedly connected to the crawler motors. The crawler is arranged on the crawler wheels. Among them, the crawler motors are powered by the battery in the sealed cabin to drive the vehicle body to move at the bottom of the net cage.

[0016] Preferably, the mechanism for winding and unwinding the traction rope is a winch, which is fixedly installed inside the fishing umbrella storage compartment. The winch drives the vehicle to move up and down inside the net cage by winding and unwinding the rope.

[0017] Preferably, the visual image acquisition unit includes multiple sets of searchlights and cameras mounted on the vehicle body.

[0018] Preferably, the lifting turntable is rotatably mounted on a turntable base, and the turntable base is telescopically mounted inside a telescopic sleeve. The telescopic sleeve is fixedly mounted on the bottom of the vehicle body. Multiple underwater electric telescopic cylinders are also fixedly mounted on the telescopic sleeve. The telescopic arms of the underwater electric telescopic cylinders are fixedly connected to the turntable base. The telescopic movement of the underwater electric telescopic cylinders drives the turntable base to move up and down, thereby driving the lifting turntable to move up and down. The turntable base is connected to the lifting turntable through a slewing bearing. Multiple rotary drive motors are also fixedly mounted on the turntable base. The drive gears connected to the drive shafts of the rotary drive motors mesh with the toothed grooves opened on the inner side of the lifting turntable. The rotation of the rotary drive motors drives the lifting turntable to rotate, thereby driving a pair of aeration rods at the bottom to rotate on a fixed axis.

[0019] Preferably, the aeration rod is a multi-stage sleeve-type telescopic mechanism, and aeration holes are arranged at equal intervals on the aeration rod. The aeration holes are connected to the floating pump through a hollow pipeline, and the floating pump performs the aeration operation. The floating pump is powered by a battery in the sealed chamber.

[0020] Preferably, the multiple sleeves of the aeration rod are connected by a traction spring. The traction spring is used to pull the sleeves without external force, so that the aeration rod is in a contracted state. During the pumping process of the floating pump, the multiple sleeves on the aeration rod overcome the elastic force of the traction spring and extend outward under the push of air pressure.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention not only cleans up bottom debris and dead fish, but also uses aeration to uniformly clean debris at different depths underwater. The bubbles generated by aeration push the water upward, creating a bubble circulation flow at the bottom of the net cage. This causes debris from different locations to gather at the aeration point and float to the surface under the push of the bubbles. The floating debris is then pushed by the water flow to spread around the net cage, where it is captured by the aeration barrier net set above. Therefore, this invention offers diverse fishing methods and a wider fishing range, thus ensuring the cleanliness of the inside of the net cage. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-5 The present invention provides a technical solution:

[0031] Example 1:

[0032] A garbage recycling robot includes:

[0033] Vehicle body 1, which is equipped with a power unit, a fishing unit, an aeration unit and a visual image acquisition unit. The vehicle body 1 also has a garbage collection compartment 2 inside.

[0034] The catching unit includes a catching port 3 located at the front of the vehicle body 1 in the direction of travel. The catching port 3 is connected to the garbage collection compartment 2. The vehicle body 1 on the side of the garbage collection compartment 2 away from the catching port 3 is also provided with an internal and external through-hole drainage port 4. The sinking garbage is caught by installing an electric drainage paddle 5 at the through-hole drainage port 4.

[0035] The fishing unit further includes a fishing umbrella storage compartment 6 provided above the vehicle body 1. The fishing umbrella storage compartment 6 is spaced apart from the garbage collection compartment 2 by a partition. A motorized opening and closing upper hatch 7 is slidably provided above the fishing umbrella storage compartment 6. A towing rope 8 is wound and unwound in the fishing umbrella storage compartment 6 by a winding mechanism. One end of the towing rope 8 away from the winding mechanism is provided with an aeration blocking net cover 9 in a towing manner;

[0036] The aeration blocking net cover 9 is composed of an annular floating airbag 10 and an annular blocking net 11. The annular blocking net 11 is connected below the annular floating airbag 10. The cross-section of the annular blocking net 11 is in an "L" shape and the open end faces the inside of the annular floating airbag 10. The aeration blocking net cover 9 is stored in the fishing umbrella storage compartment 6 in an exhaust state and floats on the water surface of the net cage during the aeration fishing process. The annular floating airbag 10 is connected to a compressed gas cylinder provided inside the vehicle body 1 through a hollow pipeline, and the annular floating airbag 10 is supplied with gas by a compressed air pump so that it inflates and floats. The compressed air pump is fixedly installed in the fishing umbrella storage compartment 6;

[0037] The aeration unit includes a pair of aeration rods 12 telescopically provided at the bottom of the vehicle body 1. The pair of aeration rods 12 are parallelly installed at the bottom of the lifting turntable 13. The lifting turntable 13 makes the aeration rods 12 retract or protrude from the lower plane of the vehicle body 1 through lifting movement. In the protruding state, the lifting turntable 13 drives the pair of aeration rods 12 to perform a rotational movement. The aeration rods 12 are connected to a floating pump 14 provided in a floating manner through a hollow pipeline. The floating pump 14 pumps the gas on the water surface through the aeration rods 12 and pushes the garbage at the bottom of the net cage to float, thereby establishing a bubble circulation flow that gathers and flows upward from the periphery of the bottom of the net cage. The fluid drives the garbage to float and disperse around and sink downward after reaching the water surface. At this time, the aeration blocking net cover 9 is used to catch and collect the settled garbage.

[0038] In this embodiment, the vehicle body 1 serves as the main structure of the device, which includes a power unit, a fishing unit, an aeration unit, and a visual image acquisition unit. Corresponding functions are achieved through the settings of different units. A garbage collection compartment 2 is arranged inside the vehicle body 1 to collect and store the waste at the bottom of the net cage. Garbage enters through the fishing port 3 at the front end of the advancing direction of the vehicle body 1. A front hatch 15 is also arranged at the fishing port 3 in a hinged and flip-up manner. The opening and closing of the fishing port 3 are controlled by the opening and closing of the front hatch 15. A deflector 16 is fixedly installed on the vehicle body 1 at the front end of the fishing port 3 to facilitate guiding the garbage into the fishing port 3. In order to suck the garbage into the fishing port 3, an electric drainage paddle 5 is installed at the blocking drainage port 4. The electric drainage paddle 5 discharges the water body in the garbage collection compartment 2, thereby accelerating the water body to enter the garbage collection compartment 2. During this process, the garbage sinking to the bottom is pushed into the garbage collection compartment 2, thus realizing the garbage collection operation. The fishing process at the bottom of the net cage is carried out under the guidance of the visual image acquisition unit. The visual image acquisition unit includes multiple groups of searchlights and cameras 22 installed on the vehicle body 1. Images are transmitted back through the signal transmission device installed inside the vehicle body 1, and then the operator is guided to perform underwater remote control operations. Of course, in the future, it can also rely on existing artificial intelligence models for autonomous recognition and operations to further improve the degree of intelligence. The above structure is a solution already disclosed in the prior art, and its structure has been disclosed in the previous application. Different from the prior art, in this embodiment, a fishing umbrella storage compartment 6 is also arranged above the vehicle body 1. The fishing umbrella storage compartment 6 is separated from the garbage collection compartment 2 by a partition, so that the two do not interfere with each other. A winch is installed in the fishing umbrella storage compartment 6, and the winding operation of the traction rope 8 is carried out through the winding and unwinding movement of the winch. One end of the traction rope 8 far from the winch is tractionally provided with an aeration blocking net cover 9. The aeration blocking net cover 9 is composed of an annular floating airbag 10 and an annular blocking net 11. The annular floating airbag 10 expands and opens under the operation of the compressed air pump arranged in the fishing umbrella storage compartment 6. In the contracted state of the annular floating airbag 10, the aeration blocking net cover 9 can be stacked as a whole and stored in the fishing umbrella storage compartment 6, and the fishing umbrella storage compartment 6 is closed by closing the upper hatch 7. The stacking and arrangement of the aeration blocking net cover 9 are carried out manually. The annular blocking net 11 is connected below the annular floating airbag 10. The cross-section of the annular blocking net 11 is in an "L" shape and the open end faces the inside of the annular floating airbag 10. Refer to the attached Figure 1 and the attached Figure 2An opening is provided on the inner side. The purpose of this design is to allow floating debris to spread outwards with the water flow, eventually entering the inner side of the annular barrier net 11 and being collected. To achieve this, an aeration unit is also installed at the bottom of the vehicle body 1. The aeration unit includes a pair of aeration rods 12 that are telescopically mounted at the bottom of the vehicle body 1 and fixedly installed at the bottom of the lifting turntable 13. The lifting turntable 13 can move up and down, so that it is retracted at the bottom of the vehicle body 1 in the normal state, thus not affecting the movement of the vehicle body 1. When aeration is required, the lifting turntable 13 is in the protruding state, and the pair of aeration rods 12 protrude from the bottom of the vehicle body 1. The rotation of the lifting turntable 13 drives the aeration rods 12 to rotate. The aeration rods 12 are connected to the floating pump 14 through hollow pipelines. The floating pump 14 pumps the gas on the water surface out through the aeration rods 12. The working principle is that the bubbles released on the bottom aeration rods 12 move upward under the action of buoyancy, thereby forming an aeration effect. If there is floating debris above the bubble, the bubble will push the debris upward. Furthermore, as the bubble rises, it pushes the water above the vehicle body 1 upward, creating a circulation. The water flows upward on the vehicle body 1 and spreads outward after reaching the surface. The water around the bottom of the vehicle body 1 continuously moves towards it, replenishing the upward-flowing water. This process promotes the surrounding water to move from the bottom towards the vehicle body 1, further pushing the floating debris towards one side of the vehicle body 1. Upon contact with the bubble, the debris continues to be pushed upward, creating a continuous cycle. During this cycle, the floating debris moves towards the top of the vehicle body 1 and spreads outward after rising. It is then captured by the aeration barrier net 9 during this diffusion process. The captured debris can be removed manually by cleaning the aeration barrier net 9. This type of debris collection device can effectively clean debris at different heights in the net cage, improving the collection method and enhancing the collection effect.

[0039] Example 2:

[0040] An arc-shaped barrier plate 17 is fixedly installed inside the vehicle body 1 on one side of the fishing port 3. A sealed compartment 18 is also provided inside the vehicle body 1 on the side away from the fishing port 3. A battery and a main board 19 are installed inside the sealed compartment 18.

[0041] The electric drainage blade 5 is located inside the garbage collection compartment 2 and a barrier net cover 20 is also fixedly installed.

[0042] In this embodiment, the mechanism inside the vehicle body 1 is further disclosed. The arc-shaped barrier plate 17 is used to block the direction of the fishing port 3, thereby preventing the captured garbage from easily escaping from the fishing port 3. The sealed chamber 18 inside the vehicle body 1 is used to protect the motor, main board 19, etc., thereby ensuring their normal operation. The barrier net cover 20 is set to filter the water discharged from the garbage collection chamber 2 and prevent garbage from flowing out.

[0043] Example 3:

[0044] The power unit includes a track motor, track wheels, and a travel track 21. The track motor is fixedly installed at the four corners of the vehicle body 1. The track wheels are fixedly and rotatably installed on the vehicle body 1 and coaxially and fixedly connected to the track motor. The track 21 is set on the track wheels. The track motor is powered by a battery in the sealed compartment 18, thereby driving the vehicle body 1 to move at the bottom of the net box.

[0045] In this embodiment, the structure of the power unit is further disclosed. It drives the vehicle body 1 to move at the bottom of the net cage through the reciprocating motion of the track 21, thereby carrying out garbage collection and retrieval operations. Since the above-mentioned power unit is a common structural form in the prior art, it will not be described in detail here.

[0046] Example 4:

[0047] The lifting turntable 13 is fixedly and rotatably mounted on the turntable base 23. The turntable base 23 is telescopically mounted inside the telescopic sleeve 24. The telescopic sleeve 24 is fixedly mounted on the bottom of the vehicle body 1. Multiple underwater electric telescopic cylinders 25 are also fixedly mounted on the telescopic sleeve 24. The telescopic arms of the underwater electric telescopic cylinders 25 are fixedly connected to the turntable base 23. The telescopic movement of the underwater electric telescopic cylinders 25 drives the turntable base 23 to move up and down, thereby driving the lifting turntable 13 to move up and down. The turntable base 23 is connected to the lifting turntable 13 through a slewing bearing. Multiple rotary drive motors 26 are also fixedly mounted on the turntable base 23. The drive gear connected to the drive shaft of the rotary drive motor 26 meshes with the tooth groove opened on the inner side of the lifting turntable 13. The rotation of the rotary drive motor 26 drives the lifting turntable 13 to rotate, thereby driving a pair of aeration rods 12 at the bottom to rotate on a fixed axis.

[0048] The aeration rod 12 is a multi-stage sleeve telescopic mechanism. Aeration holes are arranged at equal intervals on the aeration rod 12. The aeration holes are connected to the floating pump 14 through hollow pipelines. Aeration is performed by the floating pump 14, which is powered by a battery in the sealed chamber 18.

[0049] The multiple sleeves of the aeration rod 12 are connected by traction springs. The traction springs are used to pull the sleeves without external force, so that the aeration rod 12 is in a contracted state. During the pumping process of the floating pump 14, the multiple sleeves on the aeration rod 12 are pushed outward by the air pressure to overcome the elastic force of the traction springs.

[0050] In this embodiment, the lifting drive mechanism, telescopic mechanism, and specific structural diagram of the aeration rod 12 are further disclosed, as well as the aeration process. Refer to the appendix of the specification. Figure 3 Included with instruction manual Figure 4 The lifting turntable 13 is connected to the turntable seat 23 via a slewing bearing. The turntable seat 23 is mounted on the telescopic sleeve 24 in a lifting manner. The telescopic movement of the underwater electric telescopic cylinder 25 drives the turntable seat 23 to move up and down, and the rotation of the drive motor 26 causes the lifting turntable 13 to rotate. The aeration rod 12 is a multi-stage sleeve telescopic mechanism. Aeration holes are arranged at equal intervals on the aeration rod 12. Its structure is a common structure in the prior art. The multi-stage sleeves of the aeration rod 12 are connected by traction springs, so that the aeration rod 12 is in a contracted state when there is no external force. When the floating pump 14 pumps air, the gas enters the aeration rod 12 through the hollow pipeline and is discharged through the aeration holes. During this process, the multi-stage sleeves of the aeration rod 12 extend and retract outward under the increased internal pressure, thereby realizing the aeration operation. The hollow pipeline between the aeration rod 12 and the floating pump 14 is tied to the traction rope 8 and connected to the vehicle body 1.

[0051] Instructions for use: Workers lower the vehicle body 1 to the bottom of the net cage using a safety rope, keeping the rope slack. Underwater debris is identified and collected via remote control or automated program control. After cleaning, the upper hatch 7 is opened, and the solenoid valve is activated to supply air to the annular floating airbag 10 via the compressed air cylinder built into the vehicle body 1. Under buoyancy, the aeration barrier net 9 unfolds outwards towards the fishing umbrella collection compartment 6. The winch then unwinds the aeration barrier net 9, causing it to rise to the surface. Air continues to be supplied to the annular floating airbag 10 via the compressed air cylinder until it is fully deployed. At this point, air is released from the bottom of the net cage through the aeration unit. Aeration is performed, during which garbage is collected through the aeration barrier net 9. After collection, the winch is wound up while the aeration is in progress. During this winding process, the vehicle body 1 moves upward and stops aeration when it approaches the water surface. At this time, the staff outside the device is salvaged as a whole and cleans the garbage collection chamber 2 and the aeration barrier net 9. After cleaning, the gas in the annular floating airbag 10 is released, and the aeration barrier net 9 is folded and placed back into the catching umbrella collection chamber 6. The compressed air cylinder is pumped again by an external air compressor to prepare for the next garbage cleaning and catching operation.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
