Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse planting, and in particular to a full-automatic mist spraying and sprinkling device for a solar greenhouse. Background Art

[0002] A rail sprinkler is an efficient and automated fertilizing, watering, and pesticide spraying device, specifically designed for the long and narrow space of a solar greenhouse. It realizes precise movement and uniform spraying through a rail system, and is suitable for high-density planting environments such as vegetables and flowers. It has the advantages of high efficiency, pesticide and water saving, safety and environmental protection, and strong adaptability. By applying fertilizers and pesticides regularly and quantitatively, the healthy growth of greenhouse crops can be maintained, and high-efficiency planting can be achieved.

[0003] When the common greenhouse rail sprinkler equipment on the market is actually in operation, the motor wheel is mostly used to move along the bottom of the guide rail, and the motor wheel is squeezed and locked by an electric control braking part. However, this braking method is too single. When the liquid in the solution tank is full, the weight and inertia of the equipment are large. During the reciprocating movement of the moving platform for fertilizing and spraying pesticides, effective braking cannot be achieved, resulting in the platform still sliding a short distance along the bottom of the guide rail after braking, affecting the spraying range; moreover, the spraying range and angle of the traditional rail sprinkler equipment for the solution are single, and the spraying angle and range cannot be adjusted according to different greenhouse crops, thus having shortcoming in use. Summary of the Invention

[0004] The present invention discloses a full-automatic mist spraying and sprinkling device for a solar greenhouse, aiming to solve the technical problems that in the actual operation of the existing greenhouse rail sprinkler equipment, on the one hand, the braking method of the equipment is too single, resulting in the moving platform unable to achieve effective braking in the first time, and on the other hand, the spraying angle of the traditional rail sprinkler equipment for the solution is mostly fixed and cannot be adjusted according to different greenhouse crops, thus having shortcoming in use.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A full-automatic mist spraying and sprinkling device for a solar greenhouse includes a guide rail, a moving platform slidably connected to the bottom of the guide rail through a suspension cable, and motor wheels rotatably installed at both ends of the moving platform. The motor wheels are in pressing contact with the bottom of the guide rail. A locking mechanism for braking is provided on the top of the moving platform. The locking mechanism includes a double-headed hydraulic push rod fixedly installed on the top of the moving platform, and a brake plate is installed at each of the two output ends of the double-headed hydraulic push rod;

[0007] A liquid guiding mechanism for storing solution is provided at the bottom of the mobile station. The liquid guiding mechanism includes a frame plate suspended from the bottom of the mobile station by an iron chain. One side of the top of the frame plate is equipped with a pump. The output end of the pump is connected through a water outlet pipe, and the end of the water outlet pipe penetrates out from the bottom of the frame plate.

[0008] A spraying mechanism for spraying solution is provided at the bottom of the liquid guiding mechanism. The spraying mechanism includes a fixing plate fixedly installed at the bottom of the frame plate. A rotating connecting pipe is rotatably installed at the bottom of the fixing plate. The water outlet pipe and the rotating connecting pipe are connected through. The bottom of the rotating connecting pipe is connected through a five-way pipe.

[0009] A regulating mechanism is arranged outside the spraying mechanism.

[0010] The motor wheel drives the mobile station, the liquid guiding mechanism and the spraying mechanism to move along the bottom edge of the guide rail while spraying liquid. By controlling the rotation speed of the spraying mechanism, the regulating mechanism is driven to operate, so as to change the spraying range of the spraying mechanism. The mobile station is braked by controlling the locking mechanism.

[0011] By arranging a locking mechanism at the top of the mobile station, the operation of the locking mechanism is used to synchronously lock the motor wheel and the suspension cable at the same time, so as to greatly improve the braking ability of the traditional spraying equipment. At the same time, a spraying mechanism is additionally arranged at the bottom of the liquid guiding mechanism, and the water pressure is used to drive the rotation speed of the spraying mechanism to change, so as to change the working form of the spraying mechanism. With the synchronous operation of the regulating mechanism, the equipment can have various spraying angles and forms of the solution, so as to adaptively spray pesticides on crops of different heights, and greatly improve the functionality and working efficiency of the traditional guide rail pesticide spraying machine.

[0012] In a preferred solution, the locking mechanism further includes a first type of extrusion part arranged at one end of the brake plate, and a second type of extrusion part arranged at the other end of the brake plate. The first type of extrusion part is in extrusion contact with the outside of the motor wheel, and the second type of extrusion part is in extrusion contact with the bottom of the suspension cable.

[0013] By arranging two brake plate structures driven by a double-headed hydraulic push rod, the brake plates move horizontally outwards, so as to drive the first type of extrusion part and the second type of extrusion part at the end of the brake plate to move synchronously, and simultaneously brake the suspension cable and the motor wheel, greatly improving the braking ability of the traditional equipment.

[0014] In a preferred solution, the liquid guiding mechanism further includes a water tank fixedly installed at the top of the frame plate. The input end of the pump is connected through a water inlet pipe to the inside of the water tank.

[0015] By suspending a water tank structure filled with the assembly solution at the bottom of the mobile station, and using a pump to export the solution in the water tank in coordination with the horizontal movement of the mobile station, the crops inside the entire solar greenhouse are sprayed, ensuring the perfect operation of this equipment.

[0016] In a preferred solution, the spraying mechanism further includes several pipe fittings rotatably installed at the end of the five-way pipe, and a soft rubber hose is connected through the top of each pipe fitting to the inside of the five-way pipe.

[0017] By arranging a rotating pipe connection structure rotatably installed below the fixed plate at the bottom of the shelf board, using a pump to drive the solution inside the water tank into the inside of the rotating pipe, and using the water pressure to drive the synchronous rotation of the rotating pipe, the five-way pipe and the pipe fittings below the rotating pipe. Under normal conditions, the pipe fittings and the nozzles are vertically oriented towards the ground to spray the solution on the crops in the solar greenhouse. When the water pressure flowing through the inside of the rotating pipe increases, the rotation speed of the rotating pipe increases synchronously at this time, and thus the pipe fittings are driven to rotate around the five-way pipe by inertia, changing the orientation of the pipe fittings and the nozzles, so that this equipment can freely adjust the spraying angle of the solution and improve the functionality of the traditional rail spraying machine.

[0018] In a preferred solution, the control mechanism includes a threaded groove opened on the outside of each pipe fitting, a nut is threadedly connected to the outside of the threaded groove, a transfer ring is rotatably installed at the bottom of the nut, a sleeve is connected to the bottom of the transfer ring through a spring, the spring is sleeved on the outside of the pipe fitting, the sleeve is slidably sleeved on the outside of the pipe fitting through a sliding groove, and a number of liquid distribution holes are evenly opened on the outside of the sleeve and the pipe fitting, and the number of liquid distribution holes can coincide or be misaligned with each other.

[0019] By threadedly installing a nut on the outside of the pipe fitting, the nut is connected to the sleeve through the transfer ring and the spring. Under normal conditions, along with the high-speed rotation of the pipe fitting, the sleeve can overcome the pulling force of the spring and slide along the outside of the pipe fitting by its own inertia, causing the liquid distribution holes on the outside of the sleeve and the pipe fitting to align, thereby changing the liquid outlet angle and range of the pipe fitting. And the user can also actively rotate the nut to change the distribution position of the sleeve under normal conditions, so as to actively adjust the liquid outlet angle and range of the pipe fitting and improve the functionality of this equipment.

[0020] As can be seen from the above, a full-automatic mist spraying and sprinkling equipment for solar greenhouses provided by the present invention has the following technical effects.

[0021] First: By arranging two brake plate structures driven by a double-headed hydraulic push rod at the top of the mobile station, the brake plates move horizontally outwards, thereby driving a first type of extrusion part and a second type of extrusion part located at the ends of the brake plates to move synchronously, and simultaneously braking the suspension cable and the motor runner that drives the entire device to move. In the form of extrusion, the suspension cable is tilted, causing the brake pads and the guide rail to be squeezed to form a primary brake, the motor runner and the guide rail to be squeezed to form a secondary brake, and the motor runner to be directly squeezed by the brake plate to form a tertiary brake, thereby greatly improving the braking ability of the traditional track spraying device and enhancing the stability during the operation of the device.

[0022] Second: By arranging a rotating pipe structure rotatably installed below the fixed plate at the bottom of the frame plate, the pump drives the solution inside the water tank into the inside of the rotating pipe, and the water pressure drives the rotating pipe and the five-way pipe and pipe fittings below the rotating pipe to rotate synchronously. Under normal conditions, the pipe fittings and the nozzles are vertically oriented towards the ground to spray the solution on the crops in the solar greenhouse. When the water pressure flowing through the inside of the rotating pipe increases, the rotation speed of the rotating pipe increases synchronously at this time, thereby driving the pipe fittings to rotate around the five-way pipe by inertia, thus changing the orientation of the nozzles of the pipe fittings, enabling the device to freely adjust the spraying angle of the solution according to the height of the crops planted in the greenhouse and the needs of the user, thereby greatly enhancing the functionality of the traditional guide rail spraying machine.

[0023] Third: By additionally installing a nut on the outside of the pipe fitting using threads, the nut is connected to a sleeve through an adapter ring and a spring. Along with the high-speed rotation of the pipe fitting, the sleeve can slide along the outside of the pipe fitting by relying on its own inertia to overcome the tension of the spring, causing a number of liquid distribution holes that are misaligned in the normal state between the sleeve and the outside of the pipe fitting to align, thereby changing the liquid outlet angle and range of the nozzle. The user can also actively rotate the nut to change the distribution position of the sleeve in the normal state, directly aligning a number of liquid distribution holes that are misaligned in the normal state between the sleeve and the outside of the pipe fitting, thereby actively adjusting the liquid outlet angle and range of the nozzle and further enhancing the functionality of the device.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0040] A fully automatic mist spraying and sprinkling device for solar greenhouses disclosed by the present invention is mainly applied to the scenarios of spraying and irrigation, fertilization, and pesticide spraying in solar greenhouses.

[0041] Referring to Figures 1 to 14 , a fully automatic mist spraying and sprinkling device for solar greenhouses includes a guide rail 1, a moving platform 3 slidably connected to the bottom of the guide rail 1 through a suspension cable 2, and motor wheels 4 rotatably installed at both ends of the moving platform 3. The motor wheels 4 are in pressing contact with the bottom of the guide rail 1. A locking mechanism 5 for braking is arranged on the top of the moving platform 3. The locking mechanism 5 includes a double-headed hydraulic push rod 501 fixedly installed on the top of the moving platform 3, and a brake plate 502 is installed at each of the two output ends of the double-headed hydraulic push rod 501;

[0042] A liquid guiding mechanism 6 for storing the solution is arranged at the bottom of the moving platform 3. The liquid guiding mechanism 6 includes a frame plate 601 suspended at the bottom of the moving platform 3 through an iron chain. A pump 603 is mounted on one side of the top of the frame plate 601. The output end of the pump 603 is connected through a water outlet pipe 605, and the end of the water outlet pipe 605 penetrates out from the bottom of the frame plate 601;

[0043] A spraying mechanism 7 for spraying the solution is arranged at the bottom of the liquid guiding mechanism 6. The spraying mechanism 7 includes a fixing plate 701 fixedly installed at the bottom of the frame plate 601. A rotating connecting pipe 702 is rotatably installed at the bottom of the fixing plate 701. The water outlet pipe 605 and the rotating connecting pipe 702 are connected through. The bottom of the rotating connecting pipe 702 is connected through a five-way pipe 703;

[0044] A regulating mechanism 8 is arranged outside the spraying mechanism 7;

[0045] The motor wheels 4 drive the moving platform 3, the liquid guiding mechanism 6, and the spraying mechanism 7 to move along the bottom edge of the guide rail 1 while spraying the liquid. By controlling the rotation speed of the spraying mechanism 7, the regulating mechanism 8 is driven to operate, so as to change the spraying range of the spraying mechanism 7. The moving platform 3 is braked by controlling the locking mechanism 5.

[0046] In this embodiment: the operator adds solution to the inside of the liquid guiding mechanism 6, and at the same time uses the iron chain and the hook to hang the liquid guiding mechanism 6 on the bottom of the moving platform 3, and starts the whole device at the same time, the motor wheel 4 starts to rotate, driving the whole device to move slowly along the bottom of the guide rail 1, and the liquid guiding mechanism 6 runs synchronously, and the solution is introduced into the inside of the spraying mechanism 7, and the solution is sprayed out while the spraying mechanism 7 rotates, and is evenly sprayed on the crops inside the solar greenhouse; when the moving platform 3 needs to be braked, the locking mechanism 5 is operated at this time, and the locking mechanism 5 will squeeze and contact the side of the motor wheel 4 and the suspension cable 2, thereby braking the whole device; when the spraying mechanism 7 sprays and irrigates the crops inside the solar greenhouse, the operator remotely controls the liquid guiding mechanism 6 to increase the liquid guiding flow rate into the spraying mechanism 7 according to the demand, so that the rotation speed of the spraying mechanism 7 increases, and at the same time drives the regulating mechanism 8 to run synchronously to change the spraying angle and range of the spraying mechanism 7.

[0047] Reference Figures 1 to 4 In a preferred embodiment, the locking mechanism 5 also includes a first extrusion portion 503 provided at one end of the brake plate 502, and a second extrusion portion 504 is provided at the other end of the brake plate 502, the first extrusion portion 503 is extruded and contacted with the outer side of the motor wheel 4, and the second extrusion portion 504 is extruded and contacted with the bottom of the suspension cable 2, and pulleys 201 are rotatably installed at both ends of the top of each suspension cable 2, and the pulleys 201 are slidably distributed inside the guide rail 1, and a brake pad 202 is provided at the top of the suspension cable 2 and below the pulley 201.

[0048] When the moving platform 3 needs to brake, the double-headed hydraulic push rod 501 is in operation, and the output end of the double-headed hydraulic push rod 501 extends outward and pushes the brake plate 502, causing the two brake plates 502 to move toward the direction of the motor wheel 4 until the first type of extrusion portion 503 is pressed and contacted with the outer side of the motor wheel 4, thereby braking the motor wheel 4. At the same time, the second type of extrusion portion 504 is pressed and contacted with the bottom of the suspension cable 2, and the compressed suspension cable 2 is tilted, so that the brake plate 202 is in contact with the bottom of the guide rail 1, thereby performing double braking on the entire device;

[0049] Specifically, a flexible steel cable 505 is connected between the bottom of the suspension cable 2 and the moving platform 3, and the second type of extrusion portion 504 squeezes and contacts the side of the flexible steel cable 505, causing the flexible steel cable 505 and the suspension cable 2 to tilt; and a central groove 506 is opened through the top of the brake plate 502, and the flexible steel cable 505 is distributed inside the central groove 506. When the brake plate 502 moves horizontally, the flexible steel cable 505 will move synchronously along the inside of the central groove 506.

[0050] Further, it is supplemented and explained that: Connecting brackets 10 are rotatably arranged on both sides of the mobile station 3. The upper end of the connecting bracket 10 is rotatably connected to the motor runner 4. A resilient pushing member 9 is rotatably installed between the lower end of the connecting bracket 10 and the mobile station 3. The resilient pushing member 9 will squeeze and push the lower end of the connecting bracket 10, causing the connecting bracket 10 and the motor runner 4 to rotate upward around the hinge point, so that the motor runner 4 is in close contact with the bottom of the guide rail 1.

[0051] Referring to Figures 1 to 3 、 Figures 5 to 6 , in a preferred embodiment, the liquid guiding mechanism 6 further includes a water tank 602 fixedly installed on the top of the frame plate 601. The input end of the pump 603 is connected through the water inlet pipe 604 to penetrate into the interior of the water tank 602.

[0052] The operator adds the solution into the interior of the water tank 602, and at the same time uses the iron chain and the hook to hang the frame plate 601 at the bottom of the mobile station 3. Then the entire device is started, and the motor runner 4 starts to rotate, driving the entire device to slowly move along the bottom of the guide rail 1. At the same time, the pump 603 runs synchronously, extracts the solution from the interior of the water tank 602 through the water inlet pipe 604, and introduces it into the interior of the spraying mechanism 7 through the water outlet pipe 605. The spraying mechanism 7 atomizes and sprays the solution while rotating.

[0053] Referring to Figures 1 to 2 、 Figures 5 to 9 , in a preferred embodiment, the spraying mechanism 7 further includes a plurality of pipe fittings 704 rotatably installed at the end of the five-way pipe 703. A flexible rubber hose 705 is connected through the top of each pipe fitting 704 to penetrate into the interior of the five-way pipe 703. A spray head 708 is arranged at the lower end of the pipe fitting 704.

[0054] The pump 603 runs synchronously, extracts the solution from the interior of the water tank 602 through the water inlet pipe 604, and introduces it into the interior of the adapter pipe 702 through the water outlet pipe 605, causing the adapter pipe 702 to drive the five-way pipe 703 and the pipe fittings 704 to slowly rotate. At this time, the pipe fittings 704 are perpendicular to the ground. At the same time, the solution located in the interior of the adapter pipe 702 will be introduced into the interior of the pipe fittings 704 through the five-way pipe 703 and the flexible rubber hose 705 and sprayed out from the spray head 708; when the spraying mechanism 7 sprays the crops inside the solar greenhouse, the operator remotely controls the pump 603 to increase the output power according to the needs, so as to increase the liquid guiding flow rate into the interior of the adapter pipe 702 through the water outlet pipe 605, causing the rotation speed of the adapter pipe 702 to increase, thereby driving the pipe fittings 704 to rotate at a high speed. While the pipe fittings 704 are rotating, they will gradually tilt upward around the upper end rotating shaft of the five-way pipe 703 under the action of centrifugal force, thereby changing the liquid outlet angle of the spray head 708; among them, a counterweight 707 is fixedly installed at the bottom of each pipe fitting 704 to increase the inertia of the pipe fittings 704 during revolution.

[0055] Further, it should be supplemented and explained that: a spiral member 706 is fixedly installed inside the adapter pipe 702, and the solution entering the inside of the adapter pipe 702 impacts the top of the spiral member 706, thereby causing the spiral member 706 to drive the adapter pipe 702 to rotate.

[0056] Referring to Figures 7 to 9 , in a preferred embodiment, the regulating mechanism 8 includes a thread groove 801 formed on the outer side of each pipe fitting 704. A nut 802 is threadedly connected to the outer side of the thread groove 801. A transfer ring 803 is rotatably installed at the bottom of the nut 802. A sleeve 805 is connected to the bottom of the transfer ring 803 through a spring 804. The spring 804 is sleeved on the outer side of the pipe fitting 704. The sleeve 805 is slidably sleeved on the outer side of the pipe fitting 704 through a sliding groove 807. A plurality of liquid distribution holes 806 are evenly formed on the outer sides of the sleeve 805 and the pipe fitting 704, and the plurality of liquid distribution holes 806 can coincide with or be misaligned with each other.

[0057] When the pipe fitting 704 rotates at a high speed and gradually tilts upward around the upper end rotating shaft of the five-way pipe 703 under the action of centrifugal force, the sleeve 805 located on the outer side of the pipe fitting 704 will be affected by centrifugal force, overcome the tension of the spring 804 and slide along the outer side of the sleeve 805, so that the liquid distribution holes 806 located on the outer side of the sleeve 805 and the liquid distribution holes 806 located on the outer side of the pipe fitting 704 are aligned and coincide, thereby changing the flow path of the solution inside the pipe fitting 704 and increasing the liquid outlet range; and under normal conditions, the user can manually rotate the nut 802, causing the nut 802 to move along the inside of the thread groove 801, and driving the transfer ring 803, the spring 804 and the sleeve 805 to move synchronously, so that the liquid distribution holes 806 located on the outer side of the sleeve 805 and the liquid distribution holes 806 located on the outer side of the pipe fitting 704 are aligned, thereby manually changing the flow path of the solution inside the pipe fitting 704.

[0058] Working principle: During use, the operator manually adds a solution into the interior of the water tank 602. At the same time, the rack board 601 is suspended at the bottom of the moving platform 3 by means of an iron chain and a hook. Then, the entire device is started, and the motor runner 4 begins to rotate, driving the entire device to slowly move along the bottom of the guide rail 1. Meanwhile, the pump 603 operates synchronously, pumping the solution out of the interior of the water tank 602 through the water inlet pipe 604 and introducing it into the interior of the adapter pipe 702 through the water outlet pipe 605. The solution will impact the spiral member 706 to generate a rotational driving force, causing the adapter pipe 702 to be driven by the spiral member 706, thereby driving the five-way pipe 703 and the pipe fitting 704 to slowly rotate. At this time, the pipe fitting 704 and the nozzle 708 are perpendicular to the ground. Meanwhile, the solution located inside the adapter pipe 702 will be introduced into the interior of the pipe fitting 704 through the five-way pipe 703 and the flexible rubber hose 705 and sprayed out; when the spraying mechanism 7 sprays the crops inside the solar greenhouse, the operator remotely controls the pump 603 to increase the output power according to the requirements, thereby increasing the liquid guiding flow rate into the interior of the adapter pipe 702 through the water outlet pipe 605, causing the rotational speed of the adapter pipe 702 to increase, thereby driving the pipe fitting 704 to rotate at a high speed. While the pipe fitting 704 rotates, it will be gradually tilted upward around the upper rotating shaft of the five-way pipe 703 under the action of centrifugal force, thereby changing the liquid outlet angle of the nozzle 708. While the pipe fitting 704 is tilted, the sleeve 805 located outside the pipe fitting 704 will be affected by centrifugal force, overcome the pulling force of the spring 804 and slide along the outside of the sleeve 805, causing the liquid distribution holes 806 located outside the sleeve 805 to align and coincide with the liquid distribution holes 806 located outside the pipe fitting 704, thereby changing the liquid flow path inside the pipe fitting 704 and increasing the liquid outlet range. Finally, when the moving platform 3 needs to be braked, at this time, the double-headed hydraulic push rod 501 operates, and the output end of the double-headed hydraulic push rod 501 extends outward and pushes the brake plate 502, causing the two brake plates 502 to move towards the direction of the motor runner 4 until the first type of extrusion part 503 squeezes and contacts the outside of the motor runner 4, and the second type of extrusion part 504 squeezes and contacts the flexible steel cable 505 at the bottom of the suspension cable 2, causing the flexible steel cable 505 and the suspension cable 2 to be tilted, causing the brake pads 202 to squeeze the bottom of the guide rail 1, thereby forming multiple brakes;

[0059] In summary, the liquid outlet methods of the pipe fitting 704 are divided into the following several types:

[0060] First, the nut 802 is located at the upper limit position, the spring 804 is in a relaxed state, and the liquid distribution holes 806 on the outside of the sleeve 805 are misaligned with the liquid distribution holes 806 on the outside of the pipe fitting 704. At this time, the solution only sprays downward from the nozzle 708. This state can be used for spraying operations on short crops, such as Figure 10 shown;

[0061] Second, when the flow rate of the solution increases, the pipe fitting 704 rotates and tilts. At the same time, the rotational centrifugal force causes the sleeve 805 to overcome the pulling force of the spring 804 and slide along the outside of the sleeve 805, resulting in the alignment of the liquid distribution holes 806 on the outside of the sleeve 805 and the liquid distribution holes 806 on the outside of the pipe fitting 704. At this time, the solution can be sprayed out from the nozzle 708 or from the liquid distribution holes 806. In this state, the diffusion range of the solution can be increased, as Figure 12 shown;

[0062] In addition, the nozzle 708 can be sealed with a stopcock, and the pipe fitting 704 is located below the leaf surface of tall crops. In this state, only the liquid distribution holes 806 spray liquid outward, which can perform spraying operations on tall crops and is beneficial to spraying the front and back sides of the leaves of tall crops, as Figure 13 shown;

[0063] Third, the user can manually rotate the nut 802, causing the nut 802 to move downward along the thread groove 801 to the limit position, and driving the adapter ring 803, spring 804 and sleeve 805 to move synchronously, resulting in the alignment of the liquid distribution holes 806 on the outside of the sleeve 805 and the liquid distribution holes 806 on the outside of the pipe fitting 704, thereby manually changing the flow path of the solution inside the pipe fitting 704. In this state, regardless of whether the flow rate of the solution is large or small, and regardless of whether the pipe fitting 704 rotates or not, the solution can be sprayed out from the nozzle 708 or from the liquid distribution holes 806. In this state, the spraying range of short crops can be increased, as Figure 11 shown.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
