Description

Technical Field

[0001] This invention belongs to the field of fish farming technology, and in particular relates to a fish pond feeding device. Background Technology

[0002] Fish farming is an activity that involves artificially cultivating and breeding fish in specific waters or artificial environments to obtain economic benefits or meet other needs. Fish ponds are artificially constructed or modified enclosed or semi-enclosed waters used for fish farming. They are usually made of materials such as concrete, earthen embankments, and plastic sheeting and are equipped with water inlet and drainage systems, aeration equipment, etc. In fish farming, fish ponds serve as the core carrier, providing fish with a stable living space. By controlling environmental parameters such as water quality, water temperature, and dissolved oxygen, suitable growth conditions are created. At the same time, they facilitate centralized management, feeding, disease prevention and control, and high-density farming, thereby improving the growth rate, yield, and quality of fish. They are a key infrastructure for ensuring farming efficiency and achieving large-scale production.

[0003] In the existing fish farming technology system, feeding methods are mainly divided into two types: manual feeding and mechanical feeding. While manual feeding can be flexibly adjusted according to the actual activity status and feeding needs of the fish, it requires farmers to stay by the fish pond for a long time to perform timed and quantitative operations. This not only consumes a lot of manpower, but also leads to high labor intensity and low efficiency due to long-term repetitive work. Mechanical feeding, on the other hand, uses automated equipment to achieve timed feed delivery and reduces the tediousness of manual operation. However, since the delivery device is usually fixed in a specific area of ​​the fish pond, when the fish density is high, the feed can only spread from a single fixed location to the surrounding area. This causes fish closer to the delivery point to quickly gather and feed in large quantities, while fish farther away may not get enough nutrition due to untimely or insufficient feed distribution. This results in uneven feeding of the fish and ultimately affects the growth rate and farming efficiency of the fish. Summary of the Invention

[0004] This invention provides a fishpond feeding device, which aims to solve the problems mentioned in the background art regarding the existing fish feeding methods of manual feeding and mechanical feeding. Manual feeding is time-consuming and labor-intensive, while mechanical feeding is relatively fixed in location.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a fishpond feeding device, such as... Figure 1-11 As shown, the fishpond feeding device includes: a housing 1, which contains a storage bin 2 for storing fish feed and a mechanical bin 3 for providing space for installing electronic components; a weighing sensor 4 fixed to the bottom inner wall of the storage bin 2; a support plate 5 installed on top of the weighing sensor 4 and slidingly in contact with the inner wall of the housing 1 to support the fish feed, wherein the weighing sensor 4 and the support plate 5 cooperate to weigh the remaining amount of fish feed to control the feeding amount; a discharge structure set in the mechanical bin 3 for discharging fish feed; and a clamping mechanism installed at the bottom of the housing 1 to help stabilize the housing 1.

[0020] In this embodiment, when in use, the fish feed is placed in the storage bin 2 inside the box 1. The feed falls onto the support plate 5. The support plate 5 contacts the weighing sensor 4 fixed on the inner wall of the bottom of the storage bin 2. The remaining amount of fish feed is weighed by the cooperation of the weighing sensor 4 and the support plate 5 to determine the feeding amount. When feeding is required, the discharge structure in the mechanical bin 3 starts to work and outputs the fish feed in the storage bin 2. By setting up a storage bin 2 and a mechanical bin 3 inside the box 1, the space is rationally planned, which facilitates the storage of feed and the installation of electronic components. The weighing sensor 4 and the support plate 5 work together to weigh the remaining fish feed, allowing the fish farmers to control the amount of feed and avoid feed waste or underfeeding. The feed discharge structure can realize the output of fish feed to meet the feeding needs. The clamping mechanism can help stabilize the box 1, so that the feeding device remains stable during the feeding process, solving the problems of high labor costs and low efficiency of manual feeding.

[0021] In a further preferred embodiment of the present invention, the discharge structure includes an outer cylinder 6 fixed inside the mechanical chamber 3, a discharge pipe 7 installed between the outer cylinder 6 and the support plate 5, an inner cylinder 9 rotatably installed inside the outer cylinder 6 via a rotating shaft 8, the inner cylinder 9 having a feed inlet and a discharge outlet, the outer cylinder 6 having an opening, the discharge pipe 7 being connected to the feed inlet for assisting feeding, the discharge outlet being connected to the opening for discharging fish food, a first motor 10 fixed inside the mechanical chamber 3, and transmission gears 11 respectively installed on the first motor 10 and the rotating shaft 8 and meshing with each other for transmission.

[0022] In this embodiment, during the feeding operation, the fish feed in the storage bin 2 enters between the outer cylinder 6 and the inner cylinder 9 through the discharge pipe 7. At this time, the discharge pipe 7 is connected to the feed inlet on the inner cylinder 9 to assist feeding. The first motor 10 fixed in the mechanical bin 3 is started. The first motor 10 drives the transmission gear 11 installed on it to rotate. The transmission gear 11 meshes with the transmission gear 11 installed on the rotating shaft 8, thereby driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the inner cylinder 9 to rotate inside the outer cylinder 6. When the inner cylinder 9 rotates to the point where its discharge port is connected to the opening on the outer cylinder 6, the fish feed that has entered the inner cylinder 9 is discharged through the discharge port and the opening, thus realizing the feeding of fish. The switching between feeding and discharging is achieved by rotating the inner cylinder 9. The cooperation between the discharge pipe 7 and the feed inlet of the inner cylinder 9 ensures that the fish feed enters the inner cylinder 9 smoothly, assisting in a smooth feeding process. The first motor 10 and the transmission gear 11 provide power for the rotation of the inner cylinder 9, making it easy to control the timing and angle of the rotation of the inner cylinder 9, thereby controlling the discharge of the fish feed, making the feeding process more automated, and improving feeding efficiency and quality.

[0023] In a further preferred embodiment of the present invention, the clamping mechanism includes a threaded rod 12 rotatably mounted on the bottom of the housing 1, the threaded rod 12 having two threaded segments in opposite directions, a first support frame 13 and a second support frame 14 respectively threadedly sleeved on the two threaded segments, the first support frame 13 and the second support frame 14 cooperating to clamp the edge of the fish pond, and rollers 18 rotatably mounted on the first support frame 13 and the second support frame 14 respectively, the two rollers 18 being able to contact the inner wall and the outer wall of the fish pond respectively.

[0024] In this embodiment, when it is necessary to fix the feeding device to the edge of the fish pond, the threaded rod 12 installed at the bottom of the box 1 is rotated. Since the threaded rod 12 has two threaded sections in opposite directions, as the threaded rod 12 rotates, the first support frame 13 and the second support frame 14, which are respectively threaded around the two threaded sections, will move in opposite directions along the threaded rod 12. As the first support frame 13 and the second support frame 14 move, they gradually approach the edge of the fish pond until the first support frame 13 and the second support frame 14 cooperate and tightly clamp the edge of the fish pond. At the same time, the two rollers 18 will contact the inner wall and the outer wall of the fish pond respectively. The rollers 18 can roll along the inner wall and the outer wall of the fish pond to adjust the feeding position of the device. By setting a threaded rod 12 with two oppositely threaded sections, and a first support frame 13 and a second support frame 14 respectively threaded onto it, the feeding device can be easily and quickly clamped firmly to the edge of the fish pond, adapting to fish pond edges of different widths. By setting a roller 18, it can roll when in contact with the inner and outer walls of the fish pond, reducing the friction between the device and the fish pond, and the position of the device can be easily adjusted, thereby expanding the range of fish food distribution.

[0025] In a further preferred embodiment of the present invention, a fixing frame 23 is installed at the bottom of the housing 1. The fixing frame 23 is provided with a support wheel. A second limiting cylinder 24 and a first limiting cylinder 15 are rotatably installed on the fixing frame 23 and the first support frame 13, respectively. A fixing plate 22 is fixed on both the first support frame 13 and the second support frame 14. A transmission shaft 20 is rotatably installed on both fixing plates 22. A spline rod segment 17 is provided on both transmission shafts 20. Multiple spline rod segments 17 extend into the second limiting cylinder 24 and the first limiting cylinder 15 for transmission. A first chain drive group 16 for transmission is provided between the first limiting cylinder 15 and the rotating shaft 8. A first bevel gear 21 is fixed on both transmission shafts 20 and both rollers 18. Multiple first bevel gears 21 mesh in pairs for transmission.

[0026] In this embodiment, when the threaded rod 12 is rotated to move the first support frame 13 and the second support frame 14 to clamp the edge of the fish pond, the movement of the first support frame 13 drives the first limiting cylinder 15 to move. Through the cooperation of the spline rod segment 17 with the first limiting cylinder 15 and the second limiting cylinder 24, the transmission shaft 20 can rotate accordingly. At the same time, the first chain drive group 16 transmits power to the rotating shaft 8, which drives the inner cylinder 9 to rotate. When the transmission shaft 20 rotates, the power is transmitted to the roller 18 through the meshing first bevel gears 21, which cause the roller 18 to rotate. The roller 18 rolls along the inner and outer walls of the fish pond to adjust the position of the fish feed. By setting the spline rod segment 17 to cooperate with the first limiting cylinder 15 and the second limiting cylinder 24, the power is effectively transmitted during the movement of the first support frame 13 and the second support frame 14, making the transmission structure more compact and stable. By setting the first chain drive group 16, the power of the discharge structure can be transmitted to the first limiting cylinder 15, allowing the roller 18 to rotate flexibly, thereby adjusting the position of the device on the fish pond.

[0027] In a further preferred embodiment of the present invention, the second support frame 14 is provided with a collection hopper 25 for collecting excess fish food, and the second support frame 14 is provided with an adjustment member 26 for adjusting the height of the collection hopper 25 so that the fish food is removed from the water. The collection hopper 25 includes an adjustment frame 27 slidably mounted on the second support frame 14, a feed hopper 28 fixed on the adjustment frame 27 for collecting fish food, and a storage cylinder 29 detachably mounted on the bottom of the feed hopper 28 for collecting fish food. The storage cylinder 29 is provided with a filter cylinder 30 for separating the culture water and the fish food.

[0028] In this embodiment, if excess fish food falls into the fish pond during the feeding process, the collection hopper 25 set on the second support frame 14 will start to collect the sunken feed. The fish food collected by the collection hopper 28 will fall into the storage cylinder 29 that can be detached and installed at its bottom. The filter cylinder 30 set on the storage cylinder 29 can separate the aquaculture water and fish food. After feeding is completed, the collection hopper 28 is adjusted to a suitable height. During adjustment, the aquaculture water flows out through the filter cylinder 30, while the fish food remains in the storage cylinder 29, so that it is removed from the water body and the collected fish food is prevented from returning to the water and affecting the water quality. The collection hopper 25 can effectively collect excess fish food scattered during feeding, preventing fish food from accumulating in the fish pond and causing water pollution, while also reducing fish food waste. The combination of the adjusting component 26 and the adjusting frame 27 can flexibly adjust the height of the collection hopper 28 so that it is removed from the water, making it convenient to process the collected fish food and improving the ease of operation. The storage cylinder 29 can be detached and installed, making it easy to take out the collected fish food for cleaning or reuse.

[0029] In a further preferred embodiment of the present invention, a plurality of limiting rods 31 are fixed on the storage cylinder 29, and the plurality of limiting rods 31 are all L-shaped. A limiting arc plate 33 is slidably installed on the hopper 28, which can be locked outside the limiting rods 31 to stabilize the relative position of the limiting rods 31 and the hopper 28, so as to stably connect the hopper 28 and the storage cylinder 29. The limiting arc plate 33 is provided with an elastic metal sheet 34, and the elastic metal sheet 34 is provided with a bayonet. The hopper 28 is provided with a protrusion 51 that can extend into the bayonet.

[0030] In this embodiment, when installing the storage cylinder 29 and the collecting hopper 28, the storage cylinder 29 is first placed at a suitable position below the collecting hopper 28, so that the multiple L-shaped limiting rods 31 fixed on the storage cylinder 29 correspond to the collecting hopper 28. Then, the limiting arc plate 33 slidably installed on the collecting hopper 28 is pushed, so that the limiting arc plate 33 is locked outside the limiting rods 31. During the pushing process, the elastic metal sheet 34 on the limiting arc plate 33 will undergo elastic deformation. When the protrusion 51 on the collecting hopper 28 extends to the elastic metal sheet 34, the deformation will be controlled. When the elastic metal sheet 34 is in the bayonet on the 4th, it recovers part of its deformation and locks the protrusion 51. At this time, the limiting arc plate 33 is stably locked outside the limiting rod 31, thereby stabilizing the relative position of the limiting rod 31 and the collecting hopper 28, and realizing the stable connection between the collecting hopper 28 and the storage cylinder 29. When disassembling, pull the limiting arc plate 33 with force to make the elastic metal sheet 34 deform again, so that the protrusion 51 can be released from the bayonet. Then the limiting arc plate 33 can be moved out of the limiting rod 31, separating the storage cylinder 29 and the collecting hopper 28. Multiple L-shaped limiting rods 31 provide initial positioning for the connection between the storage cylinder 29 and the feed hopper 28, making the installation process more convenient. The limiting arc plate 33 can be locked outside the limiting rods 31, effectively stabilizing the relative position of the two and enhancing the stability of the connection, preventing the storage cylinder 29 from falling off during use. By setting the elastic metal sheet 34 to cooperate with the protrusion 51 and the bayonet, a locking mechanism is formed, which can realize the quick installation and disassembly of the storage cylinder 29 and the feed hopper 28 without additional tools, improving the operating efficiency and facilitating the cleaning or reuse of fish food in the storage cylinder 29.

[0031] In a further preferred embodiment of the present invention, both the second support frame 14 and the hopper 28 are provided with guide grooves, and sliders 32 connected to the limiting arc plate 33 and the adjusting frame 27 are slidably installed in the two guide grooves respectively. The guide grooves and the sliders 32 are used to limit the movement path of the adjusting frame 27 and the limiting arc plate 33.

[0032] In this embodiment, when the adjusting frame 27 is operated to adjust the height of the hopper 28, the slider 32 will move along the path set by the guide groove, thereby driving the adjusting frame 27 to move in a predetermined direction and range. Similarly, when the limiting arc plate 33 is pushed to connect or separate the storage cylinder 29 and the hopper 28, the slider 32 connected by the limiting arc plate 33 slides in the guide groove on the hopper 28. By setting guide grooves on the second support frame 14 and the hopper 28 to cooperate with the slider 32, precise guidance is provided for the movement of the adjusting frame 27 and the limiting arc plate 33. This ensures that the adjusting frame 27 will not deviate or shake when adjusting the height of the hopper 28, thus guaranteeing the stability and accuracy of the movement of the hopper 28. For the limiting arc plate 33, the cooperation between the guide grooves and the slider 32 ensures that it can reach the designated position during the movement, achieving effective engagement or disengagement with the limiting rod 31.

[0033] In a further preferred embodiment of the present invention, the adjusting member 26 includes a mounting bracket 35 fixed on the second support frame 14, a take-up shaft 36 rotatably mounted on the mounting bracket 35, a pull rope 38 connected to the adjusting frame 27 wound on the take-up shaft 36, and a second motor 37 fixed on the second support frame 14 for driving the take-up shaft 36 to rotate, the output shaft of the second motor 37 being connected to the flange of the take-up shaft 36.

[0034] In this embodiment, when it is necessary to adjust the height of the collection hopper 28 to remove it from the water, the second motor 37 is started. The operation of the second motor 37 will drive the winding shaft 36 to rotate. As the winding shaft 36 rotates, the pull rope 38 is gradually wound onto the winding shaft 36. The pull rope 38 generates an upward pulling force on the adjusting frame 27, causing the adjusting frame 27 to move upward along the guide groove on the second support frame 14, thereby driving the collection hopper 28 to move upward until it is removed from the water. When it is necessary to return the collection hopper 28 to the appropriate position, the second motor 37 is controlled to rotate in the opposite direction, and the winding shaft 36 rotates in the opposite direction accordingly. The pull rope 38 is released, and the adjusting frame 27 moves downward under the action of gravity, driving the collection hopper 28 back to the designated position. By setting a second motor 37 to drive the winding shaft 36 to rotate, the height of the collecting hopper 28 can be automatically adjusted by connecting the pull rope 38 with the adjusting frame 27. This eliminates the need for manual operation, improving the convenience and efficiency of operation. It not only reduces the labor intensity of operators, but also allows for quick and flexible adjustment of the position of the collecting hopper 28 according to actual needs, thus enhancing the practicality and intelligence level of the device.

[0035] In a further preferred embodiment of the present invention, a guide wheel 39 for guiding the pull rope 38 is rotatably mounted on the second support frame 14. The guide wheel 39 is provided with a notch for accommodating the pull rope 38. Each of the two rollers 18 is detachably mounted with a limiting ring 19 that can contact the top of the fish pond by fixing bolts.

[0036] In this embodiment, as the second motor 37 drives the winding shaft 36 to rotate, causing the pull rope 38 to lift and lower the adjusting frame 27 and the collection hopper 28, the pull rope 38 will pass through the guide wheel 39 rotatably mounted on the second support frame 14. The pull rope 38 is embedded in the notch on the guide wheel 39, ensuring that the pull rope 38 will not deviate from the predetermined path during movement, and smoothly realize the winding and unwinding action. When the device is placed on the fish pond, the limiting ring 19 can contact the top of the fish pond. As the device moves, the roller 18 rotates, and the limiting ring 19 plays the role of limiting the position of the device, preventing the device from deviating from the edge of the fish pond or falling into the fish pond during movement. By setting guide wheels 39, the movement direction of pull rope 38 can be effectively guided, reducing friction and wear of pull rope 38 during movement, extending the service life of pull rope 38, and ensuring the stability of the tension of pull rope 38 on adjustment frame 27, making the lifting process of collection hopper 28 more stable and smooth. By setting limit ring 19, it is easy to replace and adjust according to different specifications of fish ponds. Limit ring 19 contacts the top of fish pond and can limit the device to prevent the device from deviating or falling during movement.

[0037] In a further preferred embodiment of the present invention, the top of the housing 1 is hinged to a protective cover 45 for closing the housing 1, the top of the housing 1 is provided with a sealing ring, the bottom of the protective cover 45 is provided with a groove for receiving the sealing ring, the top of the housing 1 is provided with a solar panel 46, and the mechanical compartment 3 is provided with a photovoltaic battery.

[0038] In this embodiment, when it is necessary to open the box 1 for operation or maintenance, the protective cover 45 is flipped up by the rotation of the hinge to expose the inside of the box 1 for convenient operation. After the operation is completed, the protective cover 45 is flipped down so that the sealing ring at the top of the box 1 is inserted into the groove at the bottom of the protective cover 45 to close the box 1. During the use of the device, the solar panel 46 at the top of the box 1 receives sunlight and converts solar energy into electrical energy, which is then transmitted to the photovoltaic battery in the mechanical compartment 3 for storage. By setting the protective cover 45, the internal components of the housing 1 can be effectively protected, preventing dust, debris and other contaminants from entering the housing 1, avoiding damage to the internal components, and extending the service life of the device. The sealing ring and the groove cooperate to enhance the sealing performance of the housing 1, preventing rainwater and moisture from entering the housing 1, further protecting the internal components, improving the reliability and stability of the device. By setting the solar panel 46 and photovoltaic battery, the utilization and storage of solar energy can be realized, providing the device with clean and renewable energy, reducing dependence on traditional power sources and lowering the operating cost.

[0039] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a connecting plate 40 is fixed inside the mechanical chamber 3, and a connecting shaft 41 extending outside the mechanical chamber 3 is rotatably mounted on the connecting plate 40. A second bevel gear 42 is fixed on both the connecting shaft 41 and the rotating shaft 8. The two second bevel gears 42 mesh with each other for transmission. A stirring rod 43 extending outside the storage chamber 2 is rotatably mounted inside the storage chamber 2, and a second chain drive assembly 44 for transmission is provided between the connecting shaft 41 and the stirring rod 43.

[0040] In this embodiment, when the rotating shaft 8 starts to rotate, since the rotating shaft 8 and the connecting shaft 41 are both fixed with meshing second bevel gears 42, the rotation of the rotating shaft 8 will drive the connecting shaft 41 to rotate on the connecting plate 40 through the meshing transmission of the second bevel gears 42. After the connecting shaft 41 rotates, the power is transmitted to the stirring rod 43 in the storage bin 2 by means of the transmission action of the second chain drive group 44, so that the stirring rod 43 rotates in the storage bin 2. During the rotation, the stirring rod 43 will stir the fish food in the storage bin 2 to prevent the fish food from clumping, settling, etc., and to ensure the uniformity and fluidity of the fish food. Through the meshing transmission of the second bevel gear 42, the power transmission between the rotating shaft 8 and the connecting shaft 41 is realized. The setting of the second chain drive group 44 further transmits the power of the connecting shaft 41 to the stirring rod 43, so that the stirring rod 43 can rotate stably and stir the fish food in the storage bin 2. This can prevent the fish food from clumping due to long-term storage, ensure that the fish food can be smoothly discharged from the storage bin 2, improve the stability of fish food delivery, and ensure the normal feeding of fish.

[0041] In another embodiment of the present invention, the second chain drive assembly 44 includes sprockets fixed on the connecting shaft 41 and the stirring rod 43 respectively, and a chain sleeved on the two sprockets, the chain meshing with the sprockets.

[0042] In this embodiment, when the connecting shaft 41 rotates under the transmission action of the second bevel gear 42, the sprocket fixed on the connecting shaft 41 rotates accordingly. Since the chain is sleeved on the sprocket on the connecting shaft 41 and the sprocket on the stirring rod 43, and the chain meshes with the two sprockets, according to the principle of chain drive, the rotation of the sprocket on the connecting shaft 41 will drive the chain to move, and the movement of the chain will drive the sprocket on the stirring rod 43 to rotate, thereby causing the stirring rod 43 to rotate around its own axis in the storage bin 2, thereby realizing the stirring of the fish food in the storage bin 2. By adopting a transmission method that uses sprockets and chains to mesh, a stable and reliable power transmission between the connecting shaft 41 and the stirring rod 43 can be ensured, so that the stirring rod 43 rotates at a predetermined speed and direction, thereby uniformly stirring the fish food. In addition, the chain drive structure is relatively simple, and the installation and maintenance are relatively convenient, reducing the maintenance cost and difficulty of use of the device.

[0043] In another embodiment of the present invention, the outer wall of the housing 1 is provided with an illumination element 47 for providing nighttime illumination. The illumination element 47 includes an LED light strip 48 installed on the housing 1, and a protective shell 50 provided with a waterproof adhesive strip 49 to be pasted on the outer wall of the housing 1 and fitted over the LED light strip 48. The protective shell 50 is made of transparent acrylic material, and the housing 1 is provided with a light intensity sensor.

[0044] In this embodiment, when the lighting function is needed at night or in a dimly lit environment (determined by a light intensity sensor), the LED light strip 48 installed on the housing 1 is turned on, and the LED light strip 48 emits light after being powered on. The LED light strip 48 has advantages such as energy saving, high brightness, and long lifespan, providing sufficient light for nighttime operation or observation, making it convenient for users to operate, maintain, or check the fish pond. The transparent acrylic protective shell 50 not only has good light transmittance, ensuring the effective propagation of the light emitted by the LED light strip 48, but also has a certain strength and weather resistance, protecting the LED light strip 48 from external impacts, scratches, and other damage. The waterproof strip 49 further enhances the waterproof performance of the device, extends the service life of the LED light strip 48, and reduces the risk of damage to the light strip due to water intrusion.

[0045] In summary, compared with related technologies, this device can achieve quantitative feeding by using a weighing sensor 4 and a support plate 5 to weigh the remaining fish feed. It can also achieve automated output of fish feed by setting up a discharge structure, saving manpower. The device can be stabilized by setting up a clamping mechanism, and its position can be adjusted during the feeding process to expand the feeding range. The device can also collect scattered fish feed by setting up a collection hopper 25 to avoid pollution and waste.

[0046] It is worth noting that all circuits, electronic components, and modules involved in this invention are existing technologies (the weighing sensor can be a BSF120 series, the first motor 10 can be a Siemens 1FT7 servo motor, the second motor 37 can be a Lenz MCS synchronous servo motor, and the light intensity sensor can be a BH1750 digital light intensity sensor). Those skilled in the art can fully implement these technologies, so there is no need to elaborate further. The scope of protection of this invention does not involve improvements to the software and methods. This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is a mature existing technology, which is well known to those skilled in the art, and will not be described in detail here.

[0047] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
