Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Such as Figure 1-2As shown in the figure, a low-cost material transmission device includes a frame. On both sides of the top of the frame, horizontal frames 1 are symmetrically arranged. At both ends of the bottom of the horizontal frame 1, vertically arranged support frames 2 are provided. The horizontal frame 1 and the support frame 2 are detachably connected. For example, they are connected by an L-shaped frame or a T-shaped frame and are detachably fixed by bolts. To increase the stability of the frame, a horizontally arranged bottom frame 3 is provided at the bottom of the frame. The bottom frame 3 is detachably connected to the support frame 2. The bottom frame 3 is detachably connected to the support frame 2 through an L-shaped frame or a T-shaped frame. The horizontal frame 1, the support frame 2, and the bottom frame 3 are any one of square steel, angle steel, and U-shaped steel. These materials are all basic materials at the disassembly and assembly site of photovoltaic equipment, which can achieve the technical effects of on-site assembly and on-site disassembly. After disassembly, the materials can still be used, and the cost is very low.

[0028] A liftable horizontal transmission device 4 is provided inside the frame. The horizontal transmission device 4 can be horizontally or inclinedly arranged inside the frame, and the inclination angle does not exceed 30°. The horizontal transmission device 4 includes horizontally arranged frames 5 symmetrically arranged on both sides. Between the two horizontally arranged frames 5, a number of evenly distributed and detachable rollers 6 are provided. The horizontally arranged frames 5 can be made of U-shaped steel, and the U-shaped steel is provided with evenly distributed connection holes by itself, so that the installation position of the rollers 6 can be adjusted, and the disassembly and assembly are simple.

[0029] A detachable motor frame 7 is provided on the horizontally arranged frame 5 of the horizontal transmission device 4. A detachable motor 8 is installed on the motor frame 7, so that the relative distance between the motor 8, the horizontally arranged frame 5, and the rollers 6 remains a fixed distance during the lifting process of the horizontal transmission device 4. One end of the roller 6 is provided with a first rotary driven member 10. The output end of the motor 8 is provided with a first rotary driving member 9 that cooperates with the first rotary driven member 10. The first rotary driving member 9 and the first rotary driven member 10 can be rotary transmission members such as belt pulleys, sprocket wheels, and gears driven by the motor 8. The motor 8 drives the first rotary driving member 9 to rotate, and then through the rotary transmission between the first rotary driving member 9 and the first rotary driven member 10, the roller 6 is driven to rotate, so as to realize the transportation of materials on the horizontal transmission device 4.

[0030] At least two rotary connection areas are provided on the first rotary driven member 10. One rotary connection area is a power input area 11 for connecting the first rotary driven member 10 to a power source, and the other rotary connection area is a power output area 12 for connecting to other first rotary driven members 10 for subsequent power transmission.

[0031] At least two lifting guide rods 13 vertically penetrating the horizontal transmission device 4 are provided on the frame. The lifting guide rods 13 are preferably arranged between the horizontal frame 1 and the bottom frame 3, and at least two lifting guide frames are arranged on both sides of the horizontal transmission device 4 to guide the lifting path of the horizontal transmission device 4.

[0032] Such asFigure 3 As shown, a photovoltaic distribution box 14 is provided on the frame, and a photovoltaic access terminal, an energy storage device, a charging and reversing integrated machine, a forward relay and a reversing relay are provided in the photovoltaic distribution box 14. The photovoltaic access terminal, the energy storage device, the forward relay and the reversing relay are all connected to the charging and reversing integrated machine. The photovoltaic distribution box 14 can be extracted and made. When the device is needed, only the frame, the horizontal transmission device 4 and the lifting device need to be built on site. After the construction is completed, the photovoltaic distribution box 14 is directly connected to the motor 8 and the photovoltaic power supply. The operation of the device can be realized by only using on-site photovoltaic power supply, without the need for additional auxiliary power supply, so that the technology can be applied to various harsh environments and has a wide range of applications.

[0033] The transverse transmission device 4 is connected to a lifting drive device for controlling the lifting and lowering movement of the transverse transmission device 4 .

[0034] The lifting drive device includes a manual lifting device and a mechanical lifting device, wherein:

[0035] 1. Artificial lifting device

[0036] like Figure 1-2 As shown, the horizontal frame 1 of the frame is provided with a plurality of screw rods 15 penetrating the horizontal frame 1 and the cross frame 5. Both ends of the screw rods 15 are limited by nuts. When adjusting the lifting and lowering, the nut of each screw rod 15 needs to be rotated. Since this method is manually adjusted, it cannot ensure that the adjustment height of each screw rod 15 is the same, and the problem of unevenness of the horizontal transmission device 4 may occur easily, and the adjustment error is large.

[0037] 2. Mechanical lifting device

[0038] 2-1. The lifting device includes a lifting drive shaft 16. Both sides of the lifting drive shaft 16 are provided with active rubber wheels 17 that cooperate with the steel wire rope. One end of the steel wire rope is wound around the active rubber wheel 17, and the other end of the steel wire rope is connected to the steel wire rope connector 18 on the transverse transmission device 4. Specifically, the lifting drive shaft 16 is arranged at the top of one end of the frame and is detachably fixed to the frame through an auxiliary bracket. The active rubber wheel 17 is connected to the transverse transmission device 4 through the steel wire rope. Since the horizontal frame 1 is mostly made of construction steel, this steel is provided with a number of evenly distributed mounting holes, and the steel wire rope can pass through the mounting holes without the need to open a separate hole. Since the transverse transmission device 4 is relatively long, the steel wire rope needs to be repeatedly connected to the horizontal frame 5 and the horizontal frame 1. Each connection of the steel wire rope will increase the friction, that is, increase the rotational force of the lifting drive shaft 16. Therefore, fixed pulleys are provided at the connection between the horizontal frame 1 and the horizontal frame 5 and the steel wire rope to eliminate the friction of the steel wire rope and ensure the sensitivity of the lifting adjustment.

[0039] 2-2. In order to reduce the power source of the lifting drive shaft 16, the lifting drive shaft 16 and the power source of the lateral transmission device 4 are combined, that is, a motor 8 is used to realize lateral transmission and lifting adjustment. The present technology is improved on the structure of 2-1 as follows: Figure 4-5 As shown, a second rotating follower 19 is provided at one end of the lifting drive shaft 16, and a first rotating follower 10 on the transverse transmission device 4 is provided with a controllable gear 20 that cooperates with the second rotating follower 19. Preferably, a controllable gear 20 is provided on the first rotating follower 10 connected to the motor 8 to ensure that the driving force of the motor 8 is maximized.

[0040] like Figure 6-7 As shown, the controllable gear 20 includes a large gear 21, a gear sleeve 22 and a gear paddle 23, wherein the large gear 21 is fixedly connected to the first rotary follower 10, and the two are coaxial. The gear sleeve 22 is sleeved on the outside of the large gear 21 and is in transmission cooperation with the second rotary follower 19. The inner side of the gear sleeve 22 is provided with an annular cavity for accommodating the teeth of the large gear 21. The outer side of the gear sleeve 22 is provided with a rotation connection area that cooperates with the second rotary follower 19, and an annular baffle 24 is provided on both sides of the rotation connection area. In the present technology, it is preferred to set the large gear 21 at the center of the first rotary follower 10, and the two annular baffles 24 divide the outer side of the first rotary follower 10 into three areas, namely, the controllable gear 20 in the middle and the rotation connection areas on both sides.

[0041] The gear paddle 23 is rotatably arranged inside the gear sleeve 22, and a chuck 25 for rotating and locking the gear is arranged on the gear paddle 23. The gear paddle 23 can be selectively connected to the gear sleeve 22, and the gear paddle 23 is an elliptical structure or an eccentric wheel structure, which can limit the rotation angle of the gear paddle 23 and save mechanical space at the same time. As the gear paddle 23 rotates, the chuck 25 can be inserted into or out of the tooth gap of the large gear 21, so that the gear paddle 23 controls the locking and unlocking of the relative rotational movement between the gear sleeve 22 and the large gear 21.

[0042] The gear sleeve 22 is provided with a paddle cavity for mounting the gear paddle 23, and the paddle cavity is provided with a spring cavity, and the spring cavity is provided with a tension spring 26, and the tension spring 26 elastically tensions the shift ball 27, and the gear paddle 23 is provided with at least two shift slots 28 that match the shift ball 27, namely the locking shift position and the unlocking shift position. When the gear paddle 23 is in a certain shift position, the shift ball 27 is pushed into the shift slot 28 of the shift position under the action of the tension spring 26; when the shift position needs to be changed, it is only necessary to rotate the shift paddle, and the shift ball 27 is pushed back into the spring cavity, and when the gear paddle 23 is rotated to the right position, the shift ball 27 is pushed into the new shift slot 28 again, so as to realize the shift switching of the gear paddle 23.

[0043] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it based on the present invention, which will be obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
