Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module installation, and particularly relates to a photovoltaic panel auxiliary installation robot. Background Art

[0002] Since the self-weight of a single photovoltaic module is more than 20 Kg, and currently photovoltaic brackets are generally designed to longitudinally place 4 photovoltaic modules, the installation position of the highest module is about 2.5 M above the ground. This means that 5 to 6 people are required to cooperate to install the highest module, and the installation efficiency of photovoltaic modules is low, the labor intensity of workers is large, and there are also some potential safety hazards. Moreover, when installing the photovoltaic modules on the higher part of the photovoltaic bracket, workers need to step on the surface of the already installed modules to transport the modules, which easily causes hidden cracks inside the already installed photovoltaic modules, affecting the power generation of the photovoltaic module in the future and resulting in a decline in the efficiency of the photovoltaic power station.

[0003] Chinese Patent Publication No. CN209256233U discloses a photovoltaic module auxiliary installation device, which is characterized by including a traveling mechanism, a conveying mechanism, and a blanking mechanism; wherein, the traveling mechanism is mounted on the inclined surface of the photovoltaic bracket and can travel horizontally on the photovoltaic bracket; the conveying mechanism is relatively fixed on the traveling mechanism and is used for transmitting the photovoltaic module from the bottom end to the top end of the photovoltaic bracket; the blanking mechanism is mounted on the traveling mechanism and can travel horizontally relative to the traveling mechanism, and is used for grasping the photovoltaic module on the conveying mechanism and blanking it onto the photovoltaic bracket.

[0004] The above solution provides an auxiliary installation device for placing a photovoltaic panel on a bracket, but lacks a mechanism for fixing the photovoltaic panel placed on the bracket. When installing existing photovoltaic panels, it is necessary to first place the photovoltaic panel on the bracket and then fix the photovoltaic panel from below the photovoltaic panel, because the reserved fixing holes on the photovoltaic panel are located at the lower part of the photovoltaic panel. Although there is an auxiliary device that can place the photovoltaic panel on the bracket, it cannot fix the photovoltaic panel, and in the subsequent process of fixing the photovoltaic panel, it still needs to be done manually. If the photovoltaic panels are covered on the bracket by the auxiliary device, the surrounding light is easily blocked by the photovoltaic panels when the subsequent staff installs the bracket, and it is laborious for the staff to move inside the bracket, with a relatively high labor intensity. Summary of the Invention

[0005] To solve the above problems, the present invention provides a photovoltaic panel auxiliary installation robot. By arranging an extension arm at the lower part of the laying unit, one end of the extension arm is rotationally matched with the laying unit. During the rotation of the extension arm, it has a working state and an avoidance state, and a reset unit is used to adjust the two states of the extension arm. When the extension arm moves with the laying unit, when the extension arm does not contact the vertical rod, it is in the working state, and when the extension arm contacts the vertical rod, it is in the avoidance state. After the extension arm completely passes the vertical rod, the reset unit drives the extension arm to rotate from the avoidance state to the working state. In the working state, the electric screwdriver on the extension arm coincides with the through groove on the bracket and the installation hole on the photovoltaic panel. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panel.

[0006] To solve the problems of the prior art, the present invention provides a photovoltaic panel auxiliary installation robot, including a laying unit for laying the photovoltaic panel on the bracket. The bracket includes a plurality of vertical rods arranged horizontally, and the lower part of the photovoltaic panel is provided with installation holes; a fixing unit for fixing the lower part of the photovoltaic panel is arranged below the laying unit. The fixing unit includes an extension arm whose one end is rotatably arranged at the lower part of the laying unit. The end of the extension arm rotatably connected to the laying unit is called the rotating end, and the end of the extension arm rotating around the rotating end is called the planetary end. An electric screwdriver is arranged on the planetary end. When the extension arm rotates on the laying unit, it has a working state and an avoidance state. When the laying unit moves along the length direction of the bracket, the extension arm moves synchronously with the laying unit and switches to the avoidance state when it contacts the vertical rod. When the extension arm completely passes the vertical rod, the extension arm switches to the working state, and at this time, the electric screwdriver on the extension arm is aligned with the installation hole at the lower part of the photovoltaic panel. A reset unit for switching the extension arm from the avoidance state to the working state is arranged at the rotating end of the extension arm.

[0007] Preferably, the reset unit includes a first rotary driver capable of driving the extension arm to rotate.

[0008] Preferably, a rotating sleeve is fixedly arranged at the rotating end of the extension arm. A plurality of one-way teeth are fixedly arranged on the inner wall of the rotating sleeve around the axis of the rotating sleeve. A rotating column is fixedly arranged at the output end of the first rotary driver, and the rotating column extends into the rotating sleeve. An elastic piece is fixedly and obliquely arranged on the side wall of the rotating column, and the elastic piece is in one-way engagement with the one-way teeth, and the elastic force when the elastic piece bends over the one-way teeth is greater than the total weight of the extension arm provided with the electric screwdriver.

[0009] Preferably, when the extension arm rotates to the horizontal state, the acting force of the weight of the electric screwdriver on the extension arm is the largest, and the elastic force when the elastic piece bends over the one-way teeth is greater than the acting force.

[0010] Preferably, a torsion spring box is further arranged at the rotating end of the extension arm, and the torsion spring box and the rotating sleeve are respectively arranged at the lower and upper parts of the extension arm.

[0011] Preferably, a limit block is provided at one end of the extension arm. When the extension arm rotates to the working state, it contacts the limit block and stops rotating.

[0012] Preferably, a driving trolley is provided on one side of the laying unit for driving the laying unit to move along the length direction of the bracket.

[0013] Preferably, a lifting sleeve is vertically provided above the driving trolley. A lifting rod is slidably arranged in the lifting sleeve along the extending direction of the lifting sleeve. The lifting rod extends out from the upper part of the lifting sleeve. An air pump and a switching valve are provided on the side wall of the lifting sleeve. Both the air pump and the switching valve are communicated with the lifting sleeve.

[0014] Preferably, a support frame for supporting the laying unit is hinged to the upper part of the lifting rod. A sliding table is fixedly arranged on the support frame along the width direction of the support frame. The laying unit is movably arranged on the sliding table along the extending direction of the sliding table. A second rotary driver for driving the support frame to rotate is provided at the lower part of the support frame.

[0015] Preferably, the laying unit includes a plurality of rollers, and the rollers are in rolling fit with the highest position of the upper end surface of the bracket along the length direction of the bracket.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. By providing an extension arm at the lower part of the laying unit, one end of the extension arm is rotatably matched with the laying unit. During the rotation of the extension arm, it has a working state and an avoidance state, and the two states of the extension arm are adjusted by the reset unit. When the extension arm moves with the laying unit, the extension arm is in the working state when it does not contact the vertical rod, and is in the avoidance state when it contacts the vertical rod. After the extension arm completely passes the vertical rod, the reset unit drives the extension arm to rotate from the avoidance state to the working state. In the working state, the electric screwdriver on the extension arm coincides with the through groove on the bracket and the mounting hole on the photovoltaic panel. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panel.

[0018] 2. The torsion spring in the torsion spring box provides torsion for the extension arm, so that the load on the first rotary driver is reduced during the process of driving the extension arm to change from the avoidance state to the working state. At the same time, as the extension arm provided with the electric screwdriver rotates from the working state to the avoidance state, the downward turning force applied by the electric screwdriver to the extension arm gradually increases. This is because the extension arm gradually tends to be in a horizontal state during the rotation process, and the acting force of the weight of the electric screwdriver on the planetary end of the extension arm also gradually increases. In order to prevent the extension arm from continuing to rotate after passing the vertical rod due to the elastic force of the elastic sheet being less than the acting force of the electric screwdriver on the planetary end of the extension arm, the spring box provided at the rotating end of the extension arm can also reduce the load of the elastic sheet and extend the service life of the elastic sheet.

[0019] 3. By setting up the lifting rod and the lifting sleeve, after the laying unit is placed on the bracket, the switching valve is opened, and the lifting rod and the lifting sleeve are in free sliding fit in the vertical direction. When the driving cart bumps in the vertical direction during the moving process, the lifting rod and the lifting sleeve slide relative to each other, and the driving cart can still drive the laying unit through the lifting rod and the lifting sleeve.

[0034] To further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Refer to Figures 1 - 3 : A photovoltaic panel auxiliary installation robot, including a laying unit 2 for laying the photovoltaic panel 11 on the bracket 1. The bracket 1 includes a plurality of vertical rods 12 arranged horizontally. Mounting holes 111 are provided at the lower part of the photovoltaic panel 11. A fixing unit 3 for fixing the lower part of the photovoltaic panel 11 is provided below the laying unit 2. The fixing unit 3 includes an extension arm 31 whose one end is rotatably arranged at the lower part of the laying unit 2. The end of the extension arm 31 rotatably connected to the laying unit 2 is called the rotating end, and the end of the extension arm 31 rotating around the rotating end is called the planetary end. An electric screwdriver 32 is provided at the planetary end. When the extension arm 31 rotates on the laying unit 2, it has a working state and an avoidance state. When the laying unit 2 moves along the length direction of the bracket 1, the extension arm 31 moves synchronously with the laying unit 2 and switches to the avoidance state when contacting the vertical rod 12. After the extension arm 31 completely passes the vertical rod 12, the extension arm 31 switches to the working state, and at this time, the electric screwdriver 32 on the extension arm 31 is aligned with the mounting hole 111 at the lower part of the photovoltaic panel 11. A reset unit 33 for switching the extension arm 31 from the avoidance state to the working state is provided at the rotating end of the extension arm 31.

[0036] In the process of laying photovoltaics over a large area, the bracket 1 is usually arranged in a row. When installing the photovoltaic panel 11, two to three photovoltaic panels 11 are arranged on the inclined surface of the upper part of the bracket 1 along the inclined direction of the upper end face of the bracket 1 according to the size of the bracket 1. The bracket 1 used in the present invention can only install two photovoltaic panels 11 in the inclined direction of the upper end face of the bracket 1. In order to ensure the support of the bracket 1, the bracket 1 is provided with a vertical rod 12 for providing support in the vertical direction, and the bracket 1 also includes a horizontal cross bar 13. The cross bar 13 has two functions. One is to improve the supporting strength of the bracket 1, and the other is to facilitate the installation personnel to stand on the cross bar 13 to install the photovoltaic panel 11. However, since a plurality of cross bars 13 and vertical rods 12 are provided in the bracket 1, in the traditional installation operation, the staff needs to drill into the bracket 1 and step on the cross bar 13 to fix the photovoltaic panel 11 placed on the bracket 1 during the installation. Since the staff is always in a state of looking up when fixing the photovoltaic panel 11, the long-term operation puts a lot of pressure on the staff's neck, and the vertical rods 12 and cross bars 13 distributed in the bracket 1 also hinder the staff's operation, and the operation intensity is relatively large. At the same time, in the existing installation process, the photovoltaic panel 1 The process of placing the photovoltaic panel 11 on the bracket 1 also requires the operation of the staff. In order to reduce the workload of the staff, although a laying unit 2 that can automatically lay the photovoltaic panel 11 on the bracket 1 is provided in the prior art, the photovoltaic panel 11 still needs to be fixed after laying, and the fixing process still requires manual operation by the staff, and because the laying unit 2 is fast in the automatic laying process, the staff cannot keep up with the laying speed of the laying unit 2 when fixing the photovoltaic panel 11. If the laying unit 2 lays the photovoltaic panel 11 first, and the staff fixes the photovoltaic panel 11, in the process of fixing the photovoltaic panel 11, it is easy for the staff to accidentally push the adjacent photovoltaic panel 11, thereby causing the mounting hole 111 on the photovoltaic panel 11 to be offset, and the position of the photovoltaic panel 11 needs to be manually adjusted in the subsequent installation process.

[0037] In order to avoid the above situation, a fixing unit 3 is added to the existing laying unit 2, so that the fixing unit 3 can not only automatically fix the photovoltaic panel 11 as the laying unit 2 is laid, but also avoid the vertical rod 12, thereby avoiding the fixing unit 3 being blocked by the vertical rod 12 when moving with the laying unit 2. The specific structure and working process of the fixing unit 3 are as follows:

[0038] The electric screwdriver 32 in the present invention is an automatic screw feeding type electric screwdriver 32. There are two fixing units 3 in the present invention. When the laying unit 2 is placed on the bracket 1, the two fixing units 3 are arranged along the inclination direction of the upper end surface of the bracket 1. Since only two photovoltaic panels 11 can be fixedly arranged on the upper end surface of the bracket 1 in the present invention in the inclination direction of the upper end surface of the bracket 1, the two fixing units 3 can respectively correspond to the two photovoltaic panels 11. During laying, first place the laying unit 2 on the upper end surface of the bracket 1. The laying unit 2 stores a plurality of photovoltaic panels 11. The laying unit 2 can lay the photovoltaic panels 11 at the designated positions on the bracket 1. A through hole 14 coinciding with the lower mounting hole 111 of the photovoltaic panel 11 is provided on the upper end surface of the bracket 1. When the laying unit 2 lays the photovoltaic panel 11 on the bracket 1, the mounting hole 111 on the photovoltaic panel 11 coincides with the through hole 14. The positioning process of the mounting hole 111 and the through hole 14 is the prior art and will not be elaborated here. When the laying unit 2 is placed on the upper end surface of the bracket 1, the extension arm 31 rotatably arranged on the laying unit 2 is in the working state. As the laying unit 2 moves along the length direction of the bracket 1 on the bracket 1, the extension arm 31 moves synchronously with the laying unit 2. When the extension arm 31 passes by the vertical rod 12, the extension arm 31 is pushed by the vertical rod 12 to rotate. At this time, the planetary end of the extension arm 31 rotates around the rotating end, and the electric screwdriver 32 arranged on the planetary end rotates around the rotating end synchronously with the planetary end. The extension arm 31 switches from the working state to the avoidance state. A reset unit 33 for driving the extension arm 31 to rotate and reset is arranged on the rotating end of the extension arm 31. When the extension arm 31 passes by the vertical rod 12, the reset unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. When the laying unit 2 moves to the designated position and stops moving, and places the photovoltaic panel 11 on the bracket 1, at this time, the extension arm 31 has been reset by the reset unit 33, and the extension arm 31 is in the working state. The working end of the electric screwdriver 32 arranged on the extension arm 31, the through hole 14 on the bracket 1, and the mounting hole 111 of the photovoltaic panel 11 are all on the same straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11. After completion of the fixation, the laying unit 2 continues to move along the length direction of the bracket 1.

[0039] By arranging an extension arm 31 at the lower part of the laying unit 2, one end of the extension arm 31 is rotatably matched with the laying unit 2. The extension arm 31 has a working state and an avoidance state during rotation, and the two states of the extension arm 31 are adjusted by a reset unit 33. When the extension arm 31 moves with the laying unit 2, the extension arm 31 is in the working state when it does not contact the vertical rod 12, and is in the avoidance state when it contacts the vertical rod 12. After the extension arm 31 completely passes the vertical rod 12, the reset unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. In the working state, the electric screwdriver 32 on the extension arm 31 coincides with the through groove on the bracket 1 and the mounting hole 111 on the photovoltaic panel 11. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panel 11.

[0040] Refer to Figure 6 : The reset unit 33 includes a first rotary driver 331 capable of driving the extension arm 31 to rotate.

[0041] The extension arm 31 switches between the avoidance state and the working state by its own rotation. The first rotary driver 331 is preferably a servo motor. After the extension arm 31 passes the vertical rod 12, the first rotary driver 331 starts and drives the extension arm 31 to rotate and reset to the working state. When the extension arm 31 is in the working state and moves synchronously with the laying unit 2, the vertical rod 12 blocks the moving path of the extension arm 31, while when the extension arm 31 is in the avoidance state, the vertical rod 12 does not block the moving path of the extension arm 31.

[0042] Refer to Figure 9 : A rotating sleeve 332 is fixedly arranged at the rotating end of the extension arm 31. A plurality of one-way teeth 3321 are fixedly arranged on the inner wall of the rotating sleeve 332 around the axis of the rotating sleeve 332. A rotating column 333 is fixedly arranged at the output end of the first rotary driver 331. The rotating column 333 extends into the rotating sleeve 332. An elastic piece 3331 is fixedly and obliquely arranged on the side wall of the rotating column 333. The elastic piece 3331 is in one-way engagement with the one-way teeth 3321, and the elastic force when the elastic piece 3331 bends over the one-way teeth 3321 is greater than the total weight of the extension arm 31 provided with the electric screwdriver 32.

[0043] Refer to Figures 1 - 12 : When the extension arm 31 rotates to the horizontal state, the acting force of the weight of the electric screwdriver 32 on the extension arm 31 is the largest, and the elastic force when the elastic piece 3331 bends over the one-way teeth 3321 is greater than the acting force.

[0044] Refer to Figure 6 and Figure 9 : A torsion spring box 334 is further arranged at the rotating end of the extension arm 31. The torsion spring box 334 and the rotating sleeve 332 are respectively arranged at the lower and upper parts of the extension arm 31.

[0045] The torsion spring in the torsion spring box 334 provides torsion force to the extension arm 31, reducing the load on the first rotary drive 331 during the process of driving the extension arm 31 to change from the avoidance state to the working state. At the same time, as the extension arm 31 with the electric screwdriver 32 rotates from the working state to the avoidance state, the downward rotational force exerted by the electric screwdriver 32 on the extension arm 31 gradually increases. This is because the extension arm 31 gradually tends to be in a horizontal state during rotation, and the force exerted by the weight of the electric screwdriver 32 on the planetary end of the extension arm 31 also gradually increases. To prevent the extension arm 31 from continuing to rotate after passing the vertical rod 12 due to the elastic force of the elastic piece 3331 being less than the force exerted by the electric screwdriver 32 on the planetary end of the extension arm 31, the spring box provided at the rotating end of the extension arm 31 can also reduce the load on the elastic piece 3331 and extend the service life of the elastic piece 3331. When the first rotary drive 331 drives the rotating column 333 to rotate, the rotating column 333 presses and rotates the one-way gear 3321 through the elastic piece 3331, thereby causing the rotating sleeve 332 to rotate. The extension arm 31 rotates from the avoidance state to the working state under the action of the first rotary drive 331. When the extension arm 31 switches to the working state, the working end of the electric screwdriver 32, the through hole 14 on the bracket 1, and the mounting hole 111 of the photovoltaic panel 11 are all on a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11.

[0046] Refer to Figure 12 : A limit block 335 is provided at one end of the extension arm 31. When the extension arm 31 rotates to the working state, it contacts the limit block 335 and stops rotating.

[0047] In actual operation, a pressure sensor can be set on the limit block 335 to monitor the position state of the extension arm 31. When a pressure sensor is set on the limit block 335, after the first rotary drive 331 drives the extension arm 31 to contact the limit block 335, the pressure sensor detects a pressure value, indicating that the extension arm 31 contacts the limit block 335 at this time. The first rotary drive 331 stops rotating, and the working end of the electric screwdriver 32, the through hole 14 on the bracket 1, and the mounting hole 111 of the photovoltaic panel 11 are all on a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11.

[0048] Refer to Figure 5 and Figure 8 : A driving trolley 4 for driving the laying unit 2 to move along the length direction of the bracket 1 is provided on one side of the laying unit 2.

[0049] Refer to Figure 4 and Figure 11Above the driving trolley 4, a lifting sleeve 42 is vertically arranged. A lifting rod 41 is slidably arranged in the lifting sleeve 42 along the extending direction of the lifting sleeve 42. The lifting rod 41 extends out from the upper part of the lifting sleeve 42. An air pump 421 and a switching valve 422 are arranged on the side wall of the lifting sleeve 42. Both the air pump 421 and the switching valve 422 are communicated with the lifting sleeve 42.

[0050] During the movement of the driving trolley 4, the driving trolley 4 will experience bumps and undulations in the vertical direction, resulting in a change in the distance between the driving trolley 4 and the laying unit 2 in the vertical direction. In order to ensure that the driving trolley 4 will not fail to drive when pushing the laying unit 2 to move along the length direction of the bracket 1 due to the change in the distance between the driving trolley 4 and the laying unit 2 in the height direction, the lifting rod 41 and the lifting sleeve 42 are provided. After the laying unit 2 is placed on the bracket 1, the switching valve 422 is opened, and the lifting rod 41 and the lifting sleeve 42 are freely slidably matched in the vertical direction. When the driving trolley 4 experiences bumps in the vertical direction during movement, the lifting rod 41 and the lifting sleeve 42 slide relative to each other, and the driving trolley 4 can still drive the laying unit 2 through the lifting rod 41 and the lifting sleeve 42. The air pump 421 can adjust the height of the laying unit 2 when the laying unit 2 is not placed on the bracket 1. When the air pump 421 operates, the switching valve 422 is in the closed state.

[0051] Refer to Figure 5 、 Figure 8 and Figure 10 : A support frame 43 for supporting the laying unit 2 is hinged to the upper part of the lifting rod 41. A sliding table 45 is fixedly arranged on the support frame 43 along the width direction of the support frame 43. The laying unit 2 is movably arranged on the sliding table 45 along the extending direction of the sliding table 45. A second rotation driver 44 for driving the support frame 43 to rotate is arranged at the lower part of the support frame 43.

[0052] When the laying unit 2 is placed on the bracket 1, the support frame 43 is driven to rotate by the second rotation driver 44. Since the inclination angle of the upper end surface of the bracket 1 is known, after the second rotation driver 44 rotates the support frame 43 to the same inclination angle as the upper end surface of the bracket 1, the sliding table 45 enables the laying unit 2 to slide out. After the laying unit 2 completely slides out from the sliding table 45, it can move along the length direction of the bracket 1. The second rotation driver 44 is preferably a servo motor.

[0053] Refer to Figure 7 : The laying unit 2 includes a plurality of rollers 21. The rollers 21 are in rolling cooperation with the highest position of the upper end surface of the bracket 1 along the length direction of the bracket 1.

[0054] Through the rolling cooperation between the rollers 21 and the highest position of the upper end surface of the bracket 1, the friction coefficient between the laying unit 2 and the bracket 1 is reduced.

[0055] Working principle: During the laying process, the laying unit 2 is first placed on the upper end surface of the support 1. The laying unit 2 stores multiple photovoltaic panels 11, and the laying unit 2 can lay the photovoltaic panels 11 at the designated positions on the support 1. A through hole 14 that coincides with the lower mounting hole 111 of the photovoltaic panel 11 is provided on the upper end surface of the support 1. When the laying unit 2 lays the photovoltaic panel 11 on the support 1, the mounting hole 111 on the photovoltaic panel 11 coincides with the through hole 14. The positioning process of the mounting hole 111 and the through hole 14 is prior art and will not be elaborated here. When the laying unit 2 is placed on the upper end surface of the support 1, the extension arm 31 rotatably provided on the laying unit 2 is in the working state. As the laying unit 2 moves along the length direction of the support 1 on the support 1, the extension arm 31 moves synchronously with the laying unit 2. When the extension arm 31 passes by the vertical rod 12, the extension arm 31 is pushed by the vertical rod 12 to rotate. At this time, the planetary end of the extension arm 31 rotates around the rotating end, and the electric screwdriver 32 provided on the planetary end rotates around the rotating end synchronously with the planetary end. The extension arm 31 switches from the working state to the avoidance state. A reset unit 33 for driving the extension arm 31 to rotate and reset is provided on the rotating end of the extension arm 31. When the extension arm 31 passes by the vertical rod 12, the reset unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. When the laying unit 2 moves to the designated position and stops moving, and places the photovoltaic panel 11 on the support 1, at this time, the extension arm 31 has been reset by the reset unit 33, and the extension arm 31 is in the working state. The working end of the electric screwdriver 32 provided on the extension arm 31, the through hole 14 on the support 1, and the mounting hole 111 of the photovoltaic panel 11 are all in a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11. After the fixing is completed, the laying unit 2 continues to move along the length direction of the support 1.

[0056] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as a limitation to the protection scope of the present invention.
