Description

Technical Field

[0001] This invention relates to the field of sea urchin aquaculture technology, and in particular to a sea urchin aquaculture pond bottom cleaning device. Background Technology

[0002] Sea urchins are highly valued by consumers for their edible and medicinal properties. With the increasing market demand for sea urchins, the natural populations of sea urchins around the world have declined sharply due to predatory fishing. Sea urchin farming has become an effective way to protect natural resources and meet market demand.

[0003] Sea urchin farming mainly includes two methods: marine raft farming and land-based factory farming. Marine raft farming uses rafts in sea areas suitable for sea urchin growth, but it is greatly limited by seasons and climate, and sea urchins are prone to mass mortality due to weather fluctuations. Land-based factory farming, on the other hand, takes place in artificially constructed ponds and environments, is not limited by seasons and climate, and results in faster growth and higher yields, making it a rapidly developing farming method in recent years.

[0004] Factory farming involves setting up numerous sea urchin cages in the tanks of the aquaculture workshop. This leads to the inability to promptly clean uneaten feed and feces from the bottom of the tanks, polluting the water and affecting the survival rate of the sea urchins. Currently, cleaning the uneaten feed and feces from the bottom of the tank usually involves moving the sea urchin cages to another tank and then cleaning the bottom of that tank. This primitive cleaning method wastes a lot of manpower and resources, and the sea urchins are easily damaged during the transportation process, leading to their death.

[0005] Therefore, it is necessary to develop a cleaning device for the bottom of sea urchin farming ponds to efficiently clean the bottom of the ponds without moving the sea urchin farming net cages. Summary of the Invention

[0006] To address the shortcomings of related technologies, this invention provides a sea urchin aquaculture pond bottom cleaning device. This device moves along the bottom of the pond before the sea urchin aquaculture cages are removed from the pond, sucking up and transferring the deposited waste. This achieves efficient, continuous, and intelligent physical removal of pollutants from the pond bottom, reducing labor costs, minimizing the movement of sea urchin aquaculture cages, and ensuring the survival rate of sea urchins.

[0007] This invention provides a sea urchin aquaculture pond bottom cleaning device, including a body and a mobile drive component, a cleaning component, an output pipe, a delivery pump and a controller installed on the body; The mobile drive assembly includes an electric motor, a differential gear, front wheels, and rear wheels; the two rear wheels are arranged in a triangular configuration with the front wheels at the bottom of the chassis, and the front wheels are omnidirectional wheels; the electric motor distributes power to the two rear wheels through the differential gear, which has a differential lock function; when the differential lock locks the two rear wheels, the two rear wheels rotate synchronously; when the differential lock releases the lock on the two rear wheels, the differential gear allows the two rear wheels to rotate at different speeds; The cleaning assembly includes a main pipe and multiple suction pipes connected to the bottom of the main pipe along its length. A delivery pump connects the main pipe and the output pipes. The delivery pump sucks up the sludge from the bottom of the tank through the main pipe and the suction pipes and transfers the sludge from the bottom of the tank to outside the aquaculture tank or to a pollutant collection container through the output pipes. The controller is used to control the start and stop of the motor and delivery pump, as well as the switching of the differential lock status.

[0008] In some embodiments, one cleaning component is provided on each side of the machine body.

One end of the frame is hinged to the front of the machine body, and the two ends of the telescopic drive device are respectively hinged to the machine body and the frame. When the two telescopic drive devices extend, the two frames rotate away from the machine body until the axes of the two main pipes are collinear. When the two telescopic drive devices shorten, the two frames rotate closer to the machine body until the two frames fit against the machine body.

[0009] In some embodiments, the cleaning assembly further includes a mounting shaft that is rotatably connected to the frame and parallel to the main pipe, and cleaning brushes that are arranged along the length of the mounting shaft and detachably connected to the mounting shaft; the cleaning brushes are used to clean the bottom of the pool; the rotation axis of the mounting shaft is collinear with the geometric axis of the mounting shaft; The sea urchin aquaculture pond bottom cleaning equipment also includes a cleaning drive assembly, which includes a drive bevel gear rotatably connected to the front of the machine body, a motor that drives the drive bevel gear to rotate, and two driven bevel gears respectively installed at the ends of two mounting shafts; the rotation axes of the two frames are collinear with the rotation axis of the drive bevel gear; both driven bevel gears mesh with the drive bevel gear.

[0011] In some embodiments, the main unit is located between the mounting shaft and the housing.

[0012] In some embodiments, the sea urchin aquaculture pond bottom cleaning equipment also includes a battery that connects the controller, motor, differential gear, motor and delivery pump.

[0013] In some embodiments, the sea urchin aquaculture pond bottom cleaning device also includes a wireless communication module connected to the controller.

[0014] In some embodiments, the differential device includes a driving gear, a driven gear, and a linear drive. Each of the two rear wheel axles is equipped with a driven gear. The electric motor drives the driving gear to rotate, and the linear drive device drives the electric motor to move linearly back and forth along the axis of the driving gear. The controller is connected to a linear drive unit. By driving the drive gear to move linearly, the drive gear can switch between engaging only one driven gear and engaging two driven gears simultaneously. Both driven gears can engage the drive gear individually.

[0015] In some embodiments, the differential device further includes a guide shaft, a guide seat, and a slide rail; the guide shaft is connected to the end of the drive gear away from the motor and parallel to the axis of the drive gear; the guide seat is mounted on the machine body, and the guide shaft passes through and is slidably connected to the guide seat; the slide rail is mounted on the machine body, and the motor is slidably connected to the slide rail; the bottom surfaces of the slide rail and the guide seat are connected to the machine body.

[0016] In some embodiments, the motion drive assembly further includes a connector, with the axles of the two rear wheels rotatably connected to both ends of the connector, a drive gear located on the side of the connector, and a linear drive device located on the side of the drive gear.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention can move the sea urchin farming net cages at the bottom of the pond before they are moved from the pond body, and suck up and transfer the dirt deposited at the bottom of the pond. This achieves efficient, continuous and intelligent physical removal of pollutants at the bottom of the pond, reduces labor costs, reduces the movement of sea urchin farming net cages, and ensures the survival rate of sea urchins.

[0018] 2. In this invention, the telescopic drive device can shorten the frame to fit the machine body, thereby reducing the overall width of the equipment and facilitating its movement and storage in the walkway or equipment storage area next to the breeding pond; the extension of the telescopic drive device can push the two side frames to rotate and unfold outward, so that the two cleaning components can cover a wider cleaning width, significantly improving the efficiency of a single operation.

[0019] 3. In this invention, the rotation axes of the two frames are collinear with the rotation axis of the active bevel gear, ensuring that the bevel gear transmission can still maintain correct meshing when the two frames are unfolded or retracted, achieving the effect of a single motor driving the rotation of two mounting shafts, reducing the number of motors and lowering the manufacturing and maintenance costs of the equipment.

[0020] 4. In this invention, the cover forms a relatively enclosed space, which can effectively contain the sewage and dirt stirred up by the rotating cleaning brush, improve the suction efficiency, and also help prevent dirt from spreading to the outside of the equipment or the surrounding sea urchin farming cages, reducing secondary pollution to the farming environment.

[0021] 5. The differential device in this invention has a simple and reliable structure, high durability, and adopts a horizontal layout, which effectively reduces the overall height of the entire differential device and makes the equipment chassis lower. This not only improves the stability of the equipment when traveling on the bottom of the pool and reduces the risk of overturning, but also makes it easier for the equipment to pass through environments with shallow water depth or limited space at the bottom of the net cage.

[0024] The technical solutions in 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] like Figures 1-5 As shown, in an illustrative embodiment of the sea urchin aquaculture pond bottom cleaning device of the present invention, the sea urchin aquaculture pond bottom cleaning device includes a body 6 and a mobile drive assembly, a cleaning assembly 2, an output pipe 4, a delivery pump 3 and a controller installed on the body 6. The mobile drive assembly includes a motor 11, a differential device 12, a front wheel 13, and a rear wheel 14. The two rear wheels 14 and the front wheel 13 are arranged in a triangular configuration at the bottom of the machine body 6, and the front wheel 13 is a caster wheel. The motor 11 distributes power to the two rear wheels 14 through the differential device 12, which has a differential lock function. When the differential lock is released from the two rear wheels, the two rear wheels 14 rotate synchronously. When the differential lock is locked on the two rear wheels 14, the differential device 12 allows the two rear wheels 14 to rotate at different speeds. When the equipment needs to travel in a straight line, the controller adjusts the differential lock to switch the locking state to lock the two rear wheels 14, so that the two rear wheels 14 rotate at the same speed, thus propelling the machine body 6 to travel in a straight line. When the equipment needs to turn, the controller adjusts the differential lock to switch to unlock state, so as to release the lock on the two rear wheels 14, so that the power of the motor 11 is transmitted to only one rear wheel 14, and the other rear wheel 14 moves with no power. The machine body 6 deflects and moves in the direction of the unpowered rear wheel 14.

[0029] The cleaning component 2 includes a main pipe 21 and multiple suction pipes 23 connected to the bottom of the main pipe 21 along the length of the main pipe 21. The delivery pump 3 is connected to the main pipe 21 and the output pipe 4. The delivery pump 3 sucks up the dirt from the bottom of the pool through the main pipe 21 and the suction pipes 23 and transfers the dirt from the bottom of the pool to the outside of the aquaculture pool or to a pollutant collection container through the output pipe 4. The controller is used to control the start and stop of the motor 11 and the delivery pump 3, as well as the switching of the differential lock status.

[0030] The aforementioned equipment can be moved along the bottom of the pond before the sea urchin farming net cages are removed from the pond body. During this process, the pump 3 can directly suck up uneaten feed, feces, and other waste deposited on the bottom of the pond and transfer them outside the pond or to a collection container. This achieves efficient and continuous physical removal of pollutants from the bottom of the pond, replacing the traditional method of manually moving the net cages and then cleaning the bottom of the pond. This significantly reduces manpower consumption and operation time, and greatly reduces the risk of mechanical damage to the sea urchins caused by squeezing and collisions during the handling of the net cages, which is beneficial to ensuring the survival rate of the sea urchins. The start and stop of the motor 11, the operation of the pump 3, and the opening and closing of the differential lock are all integrated and controlled by the controller, allowing for centralized control of the entire cleaning process and improving the convenience and coordination of equipment operation.

[0031] Furthermore, a non-contact displacement sensor is installed at the front of the machine to detect obstacles. The detection direction of the displacement sensor is the same as the direction of travel of the equipment. The controller determines the distance between the equipment and the pool wall based on the detection signal of the displacement sensor, so as to determine the timing of opening and closing the differential lock and avoid the equipment from colliding with the pool wall.

[0032] The displacement sensor is an infrared displacement sensor, which has the least impact on animals among all non-contact displacement sensors that can detect obstacles underwater.

[0033] In some embodiments, cleaning components 2 are provided on both sides of the body 6. The cleaning components 2 also include a frame 24 and a telescopic drive device 25, which is an electric cylinder or an electric push rod. The main pipe 21 is installed on the frame 24, and the delivery pump 3 is installed on the body 6. The two main pipes 21 are respectively connected to the delivery pump 3 through two flexible pipes 22. One end of the frame 24 is hinged to the front of the body 6, and the two ends of the telescopic drive device 25 are respectively hinged to the body 6 and the frame 24. When the two telescopic drive devices 25 extend, the two frames 24 rotate away from the body 6 until the axes of the two main pipes 21 are collinear. When the two telescopic drive devices 25 shorten, the two frames 24 rotate closer to the body 6 until the two frames 24 are in contact with the body 6.

[0034] When the equipment is not in operation or needs to pass through narrow areas, the telescopic drive device 25 can shorten the frame 24 to fit against the body 6, thereby reducing the overall width of the equipment and facilitating its movement and storage in walkways or storage areas next to the aquaculture ponds. When cleaning is required, the telescopic drive device 25 pushes the two side frames 24 to rotate outward and unfold until the axes of the two main pipes 21 are collinear. This allows the left and right cleaning components 2 to cover a wider cleaning width, cleaning a larger area of ​​the pond bottom at once, significantly improving the efficiency of a single operation, especially suitable for scenarios with wide aquaculture ponds. The two side cleaning components 2 are connected to the same delivery pump 3 through flexible pipes 22, which not only ensures concentrated and stable suction, but also adapts to positional changes during the unfolding and retraction of the frame 24 through flexible connection, avoiding pipe twisting or detachment and ensuring smooth waste transport. This extendable and retractable structural design ensures efficient cleaning while taking into account the equipment's mobility and storage convenience, further enhancing the equipment's adaptability to continuous multi-pond operation in factory-style aquaculture workshops.

[0035] In some embodiments, the cleaning assembly 2 further includes a mounting shaft 26 that is rotatably connected to the frame 24 and parallel to the main tube 21, and a cleaning brush 27 that is arranged along the length of the mounting shaft 26 and detachably connected to the mounting shaft 26; the cleaning brush 27 is used to clean the bottom of the pool; the rotation axis of the mounting shaft 26 is collinear with the geometric axis of the mounting shaft 26; The sea urchin aquaculture pond bottom cleaning equipment also includes a cleaning drive assembly 5, which includes an active bevel gear 51 rotatably connected to the front of the body 6, a motor 52 that drives the active bevel gear 51 to rotate, and two driven bevel gears 53 respectively installed at the ends of two mounting shafts 26; the rotation axes of the two frames 24 are collinear with the rotation axis of the active bevel gear 51; both driven bevel gears 53 mesh with the active bevel gear 51.

[0036] The cleaning brush 27 can scrub the bottom of the pool, agitating and loosening firmly attached dirt or sediment, making it easier for the subsequent suction pipe to suck up, thus improving the cleaning effect on hardened or sticky pollutants. The cleaning drive assembly 5 drives the active bevel gear 51 through the motor 52, which drives the driven bevel gears 53 at the ends of the two mounting shafts 26 to rotate synchronously, thereby driving the cleaning brush 27 to rotate, realizing the active scrubbing function. Compared with passive cleaning that relies solely on suction, active scrubbing can more thoroughly remove biofilm or stubborn stains from the bottom of the pool, helping to maintain the hygiene of the pool bottom environment. The rotation axis of the two frames 24 is collinear with the rotation axis of the active bevel gear 51, ensuring that the bevel gear transmission can still maintain correct meshing when the two frames 24 are extended or retracted, achieving the effect of a single motor 52 driving the rotation of two mounting shafts 26, reducing the number of motors 52 and lowering the manufacturing and maintenance costs of the equipment. The detachable design of the cleaning brush 27 also makes it easy to replace the bristles with different hardness or shape according to the degree of pollution of the pool bottom, enhancing the equipment's adaptability to different pollution conditions.

[0037] In some embodiments, the frame 24 includes a cover 241 and a hinge 242; the cleaning brush 27, the telescopic drive device 25, the main tube 21 and the suction tube 23 are all located inside the cover 241, the bottom of the cover 241 is provided with an opening, the side wall of the cover 241 is provided with a clearance opening 2411, the telescopic drive device 25 passes through the clearance opening 2411 and can swing within the clearance opening 2411.

[0038] The enclosure 241 forms a relatively enclosed space, which can effectively contain the sewage and dirt stirred up by the rotating cleaning brush 27, improve the suction efficiency, and also help prevent dirt from spreading to the outside of the equipment or the surrounding sea urchin farming cages, reducing secondary pollution to the farming environment. The opening at the bottom of the enclosure 241 allows the cleaning brush 27 and the suction pipe 23 to contact the bottom of the pool, while the side wall clearance opening 2411 allows the telescopic drive device 25 to pass through and swing inside, so that the extension and retraction of the frame 24 is not interfered with by the enclosure 241, maintaining the smoothness of the structural movement. The overall design of the enclosure 241 also protects the internal cleaning components 2, preventing external debris from entering and affecting the transmission or clogging the pipes, thus extending the service life of the equipment.

[0039] In some embodiments, the main shaft 21 is located between the mounting shaft 26 and the body 6.

[0040] The internal spatial layout of the cleaning component 2 has been optimized, with the main pipe 21 positioned closer to the body 6. This allows the dirt collected from the suction pipe 23 to enter the main pipe 21 via a shorter path, reducing the possibility of dirt accumulation in the pipe and improving the suction efficiency of the delivery pump 3. The longitudinally staggered arrangement of the main pipe 21 and the mounting shaft 26 also avoids interference between the two during movement, ensuring that the rotation of the cleaning brush 27 and the dirt suction process are synchronized and do not interfere with each other.

[0041] In some embodiments, the sea urchin aquaculture pond bottom cleaning equipment also includes a battery that connects the controller, motor 11, differential device 12, motor 52 and delivery pump 3.

[0042] The storage battery provides independent power to the motor 11, differential gear 12, motor 52, and delivery pump 3, freeing the equipment from dependence on external power cables. It can move freely within the aquaculture pond without worrying about cable dragging, tangling, or leakage risks, significantly improving the operational safety and freedom of movement of the equipment in humid and watery environments. Battery power also makes the equipment suitable for aquaculture ponds without fixed power interfaces or aquaculture workshops in remote areas, enhancing the equipment's versatility and deployment flexibility. In addition, the connection between the storage battery and the controller enables centralized management of the equipment's energy consumption, extending the operating time after a single charge by rationally allocating power.

[0043] In some embodiments, the sea urchin aquaculture pond bottom cleaning device also includes a wireless communication module connected to the controller.

[0044] Operators can remotely control the equipment's start and stop, adjust the differential lock status, and monitor operating parameters via wireless terminals (such as remote controls, mobile phones, or computers) without having to approach the pool or enter a damp environment, thus improving the operators' working conditions. This is especially suitable for use in aquaculture workshops with strict hygiene requirements or limited space. Wireless communication also facilitates the collaborative operation of multiple devices or integration into the central control system of the aquaculture workshop, enabling automated and intelligent aquaculture management. At the same time, the remote monitoring function can obtain the equipment's operating status in real time, promptly detect faults and issue warnings, and improve maintenance efficiency.

[0045] In some embodiments, the body 6 is provided with an openable and closable cavity for accommodating the differential device 12, the electric motor 11, the controller, the delivery pump 3, the battery, and the wireless communication module, so as to protect the differential device 12, the electric motor 11, the controller, the delivery pump 3, the battery, and the wireless communication module.

[0046] In some embodiments, the differential 12 includes a drive gear 121, a driven gear 122, and a linear drive 123; A driven gear 122 is installed on each of the axles of the two rear wheels 14. The motor 11 drives the driving gear 121 to rotate, and the linear drive device 123 drives the motor 11 to move linearly back and forth along the axis of the driving gear 121. The controller is connected to the linear drive device 123. By driving the drive gear 121 to move linearly, the drive gear 121 can switch between engaging only one driven gear 122 and engaging both driven gears 122 simultaneously. Both driven gears 122 can engage the drive gear 121 individually.

[0047] When the equipment needs to move straight or the bottom of the pool is flat, the controller drives the linear drive device 123 to make the drive gear 121 simultaneously mesh with the two driven gears 122, and the two rear wheels 14 rotate synchronously to provide stable driving force. When turning is required or differential speed is needed when encountering uneven bottom of the pool, the drive gear 121 moves linearly to mesh with only one side of the driven gear 122, and the rear wheel 14 on that side receives power, while the other side rotates freely, thereby realizing differential speed. This mechanical differential structure is simpler and more reliable than the traditional electronic differential, and has better durability in humid and dusty aquaculture environments. Moreover, the differential lock function is realized by switching the meshing state, without the need for a complex clutch or electronic control unit, which reduces equipment cost and failure rate.

[0048] In some embodiments, the differential device 12 further includes a guide shaft 124, a guide seat 125, and a slide rail 126; the guide shaft 124 is connected to the end of the drive gear 121 away from the motor 11 and is parallel to the axis of the drive gear 121; the guide seat 125 is mounted on the body 6, and the guide shaft 124 passes through and is slidably connected to the guide seat 125; the slide rail 126 is mounted on the body 6, and the motor 11 is slidably connected to the slide rail 126; the bottom surfaces of the slide rail 126 and the guide seat 125 are connected to the body 6.

[0049] The cooperation between the guide shaft 124 and the guide seat 125 provides precise guidance for the linear movement of the drive gear 121, ensuring that the drive gear 121 always maintains the correct meshing position with the driven gear 122 during movement, avoiding gear damage or transmission failure due to misalignment; the slide rail 126 provides precise guidance for the linear movement of the motor 11; these structures enhance the mechanical stability and lifespan of the entire differential device 12 under long-term, high-frequency use.

[0050] In some embodiments, the motion drive assembly further includes a connector 15, with the axles of the two rear wheels 14 rotatably connected to both ends of the connector 15 to ensure the coaxiality of the two rear wheels 14. The drive gear 121 is located on the side of the connector 15, and the linear drive device 123 is located on the side of the drive gear 121 to reduce the height of the differential device 12.

[0051] This horizontal layout effectively reduces the overall height of the differential device 12, making the equipment chassis lower. This not only improves the stability of the equipment when traveling on the bottom of the pool and reduces the risk of overturning, but also makes it easier for the equipment to pass through environments with shallow water depth or limited space at the bottom of the net cage.

[0052] Furthermore, the motor 52 in the cleaning drive assembly 5 is a hollow shaft motor to further reduce the height of the equipment. The hollow shaft motor is connected to the body 6 via a connecting bracket 54.

[0053] Through the description of several embodiments of the sea urchin aquaculture pond bottom cleaning device of the present invention, it can be seen that the embodiments of the sea urchin aquaculture pond bottom cleaning device of the present invention have at least one or more of the following advantages: 1. This invention can move the sea urchin farming net cages at the bottom of the pond before they are moved from the pond body, and suck up and transfer the dirt deposited at the bottom of the pond. This achieves efficient, continuous and intelligent physical removal of pollutants at the bottom of the pond, reduces labor costs, reduces the movement of sea urchin farming net cages, and ensures the survival rate of sea urchins.

[0054] 2. In this invention, the telescopic drive device can shorten the frame to fit the machine body, thereby reducing the overall width of the equipment and facilitating its movement and storage in the walkway or equipment storage area next to the breeding pond; the extension of the telescopic drive device can push the two side frames to rotate and unfold outward, so that the two cleaning components can cover a wider cleaning width, significantly improving the efficiency of a single operation.

[0055] 3. In this invention, the rotation axes of the two frames are collinear with the rotation axis of the active bevel gear, ensuring that the bevel gear transmission can still maintain correct meshing when the two frames are unfolded or retracted, achieving the effect of a single motor driving the rotation of two mounting shafts, reducing the number of motors and lowering the manufacturing and maintenance costs of the equipment.

[0056] 4. In this invention, the cover forms a relatively enclosed space, which can effectively contain the sewage and dirt stirred up by the rotating cleaning brush, improve the suction efficiency, and also help prevent dirt from spreading to the outside of the equipment or the surrounding sea urchin farming cages, reducing secondary pollution to the farming environment.

[0057] 5. The differential device in this invention has a simple and reliable structure, high durability, and adopts a horizontal layout, which effectively reduces the overall height of the entire differential device and makes the equipment chassis lower. This not only improves the stability of the equipment when traveling on the bottom of the pool and reduces the risk of overturning, but also makes it easier for the equipment to pass through environments with shallow water depth or limited space at the bottom of the net cage.

[0058] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
