Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic installation, and specifically to an automatic photovoltaic panel installation device. Background Technique

[0002] A photovoltaic panel is a power generation device that generates direct current when exposed to sunlight. It is a thin solid photovoltaic cell almost entirely made of semiconductor materials. To ensure the stability of the photovoltaic panel, it is usually necessary to install the photovoltaic panel on a fixing rack for use;

[0003] Referring to a Chinese patent with the application number 202311369187.8, an automatic photovoltaic panel installation device is disclosed. The overall process is automated and can be freely adjusted according to installation requirements, with a wide range of applications. Through research on the above automatic photovoltaic panel installation device, it is found that the above device can only automatically transport the photovoltaic panel to the top of the fixing rack, but does not involve how to fixedly connect the photovoltaic panel to the fixing rack. That is to say, after the device transports the photovoltaic panel to the top of the fixing rack and adjusts the angle, manual assembly of bolts at various parts of the photovoltaic panel is required, resulting in low operation efficiency and being particularly laborious for large-area photovoltaic installations.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] 1.

Compared with the prior art, the installation efficiency is high.

[0043] 2. In the present invention, the L-shaped metal block is pushed upward by the output rod of the No. 2 cylinder, thereby driving the push bar to move upward. The upward movement of the push bar drives the upper and lower metal pressure plates to move upward together, so that the tops of the two elastic plastic pressure strips hinged to the push bar move upward, causing the curvature of the two elastic plastic pressure strips to decrease and gradually move closer to the middle, limiting the nut of the mounting bolt inside the hexagonal socket wrench. At the same time, the left and right elastic plastic pressure strips clamp the threaded outer wall of the mounting bolt to prevent the bolt from shaking, so that it can better fit with the threaded hole on the fixing frame during the subsequent installation process, and also prevent the mounting bolt from falling off from the inside of the hexagonal socket wrench.

[0044] 3. In the present invention, after the mounting bolt is screwed into the threaded hole, the output rod of the No. 2 cylinder pulls the L-shaped metal block downward, further driving the push bar to move downward. The downward movement of the push bar drives the upper and lower metal pressure plates to move together, exerting downward pressure on the top of the left and right elastic plastic pressure strips, causing the left and right elastic plastic pressure strips to be stretched open, making it convenient for the nut part of the mounting bolt to pass through the countersunk groove and the inside of the round hole.

Detailed implementation mode

[0054] 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. 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.

[0055] Please refer to Figures 1 to 8 , the technical solutions provided by the present invention specifically include the following embodiments:

[0056] An automatic PV panel installation device includes a base 100, a lifting device 200, a PV panel feeding component 300, a bolt limiting component 400, and a bolt screwing component 500. The base 100 is used for supporting the installation of the device. The lifting device 200 is fixedly installed at the rear end of the top of the base 100 and is used for the lifting of the installation device. The PV panel feeding component 300 is fixedly installed on the front of the lifting device 200 and is used for the feeding of PV. The bolt limiting component 400 is fixedly installed on the left and right parts of the PV panel feeding component 300 and is used for the limiting of the installation bolts. The bolt screwing component 500 is fixedly installed on the back of the bolt limiting component 400 and is used for tightening the PV installation bolts. Four corners of the bottom of the base 100 are fixedly installed with Fuma casters.

[0057] Further, specifically refer to Figures 2 to 4 as shown:

[0058] The photovoltaic panel loading component 300 includes a square tube frame 301, a flipping frame 302, a connecting plate 303, suction cups 304, a push-pull block 305, and an electric cylinder 306. The square tube frame 301 is fixedly installed at the lifting end of the lifting device 200. The flipping frame 302 is hinged to the top of the square tube frame 301. The connecting plate 303 is fixedly installed inside the flipping frame 302. The suction cups 304 are fixedly installed on the front of the connecting plate 303 in a vertical and horizontal distribution and are equally spaced. The push-pull block 305 is fixedly installed on the back of the flipping frame 302. The electric cylinder 306 is hinged to the rear end of the top of the square tube frame 301, and the end of the output rod of the electric cylinder 306 is hinged to the back of the push-pull block 305 through a spherical plain bearing.

[0059] Specifically, the entire device is supported by four Fuma wheels provided at the bottom of the base 100 and is provided with a moving function. The device is moved to the photovoltaic installation position. The photovoltaic panel is placed on the front of the photovoltaic panel loading component 300. The photovoltaic panel is adsorbed by a plurality of suction cups 304. The lifting device 200 is used to push the square tube frame 301 upward (this lifting device 200 includes but is not limited to an electric lifting platform, which is a prior art means and will not be described in detail). The upward movement of the square tube frame 301 drives the overall upward movement of the photovoltaic panel loading component 300, the bolt limiting component 400, and the bolt screwing component 500. The photovoltaic panel adsorbed by a plurality of suction cups 304 is lifted upward to the installation height. Subsequently, the output rod of the electric cylinder 306 is used to push the push-pull block 305 to move, so that the photovoltaic panel loading component 300, the bolt limiting component 400, the bolt screwing component 500, and the adsorbed photovoltaic panel rotate forward along the top of the square tube frame 301 until the angle of the photovoltaic panel coincides with the inclination angle of the fixed frame, and the bottom of the photovoltaic panel abuts against the top of the fixed frame, completing the combination of the photovoltaic panel and the fixed frame.

[0060] Further, specifically referring to Figures 5 to 7 and Figure 8 shown in:

[0061] The bolt limiting component 400 includes a limiting plate 401, a round hole 402, a sunk groove 403, a sliding groove 404, a positioning hole 405, an elastic plastic pressing strip 406, a metal pressing plate 407, a pushing strip 408, an L-shaped metal block 409, and a second cylinder 4010. The limiting plate 401 is fixedly installed on the left and right sides of the flipping frame 302. The round hole 402 is opened in the upper and lower parts of the front surface of the limiting plate 401. The sunk groove 403 is opened on the rear walls of the upper and lower two round holes 402 and penetrates through the inside of the limiting plate 401. The sliding groove 404 is opened in the upper and lower parts of the side surface of the limiting plate 401 away from the flipping frame 302. The inside of the sliding groove 404 is communicated with the inside of the round hole 402. The positioning hole 405 is symmetrically opened on the left and right sides of the central axis of the round hole 402 at the lower part of the rear wall of the round hole 402. The elastic plastic pressing strip 406 is symmetrically arranged on the left and right sides of the central axis of the round hole 402 inside the round hole 402, and its bottom is hinged to the periphery of the opening of the positioning hole 405 through a pin. The two elastic plastic pressing strips 406 are symmetrically arched outwards in an arc shape. The metal pressing plate 407 is slidably installed inside the sliding groove 404 and extends into the inside of the round hole 402. The metal pressing plate 407 is hinged to the tops of the two positioning holes 405 through pins. The pushing strip 408 is slidably installed on the side surface of the limiting plate 401 away from the flipping frame 302, and the upper and lower ends of the pushing strip 408 are fixedly connected to the upper and lower two metal pressing plates 407 respectively. The L-shaped metal block 409 is fixedly installed on the outside of the pushing strip 408. The second cylinder 4010 is fixedly installed on the back surface of the limiting plate 401 through a fixed bracket, and the top of its output rod is fixedly connected to the bottom of the L-shaped metal block 409. The output end of the suction cup 304 is connected to the output end of an external negative pressure device through a soft conduit. The front surface of the suction cup 304 protrudes 10 ± 1 mm from the front surface of the limiting plate 401.

[0062] Specifically, the nuts of the four mounting bolts are placed inside the four hexagonal socket wrenches 505, so that the threaded parts of the mounting bolts pass through the recessed groove 403. Then, the No. 2 cylinder 4010 is started, and the L-shaped metal block 409 is pushed upward by the output rod of the No. 2 cylinder 4010, thereby driving the push bar 408 to move upward. The upward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move upward together, so that the tops of the two elastic plastic pressure strips 406 hinged to the push bar 408 move upward, causing the arcs of the two elastic plastic pressure strips 406 to decrease and gradually move closer to the middle, limiting the nuts of the mounting bolts inside the hexagonal socket wrench 505. At the same time, the left and right elastic plastic pressure strips 406 clamp the threaded outer wall of the mounting bolts. In order to prevent the bolt from shaking and to facilitate better connection with the threaded hole on the fixing frame during the subsequent installation process, the installation bolt is tightened into the threaded hole at the top of the fixing frame through the bolt screwing component 500, and after the installation bolt is screwed into a part of the inner threaded hole at the top of the fixing frame, the L-shaped metal block 409 is pulled downward by the output rod of the No. 2 cylinder 4010 to move, further driving the push bar 408 to move downward together, and the downward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move together, applying downward pressure on the top of the left and right elastic plastic pressure strips 406, causing the left and right elastic plastic pressure strips 406 to be stretched open, making it convenient for the nut part of the installation bolt to pass through the countersunk groove 403 and the inside of the round hole 402.

[0063] For further details, please refer to Figure 5 , Figure 6 as well as Figure 8 As shown:

[0064] The bolt screwing component 500 includes a guide post 501, a linear bearing 502, a movable plate 503, a high-torque reduction motor 504, a hexagonal socket wrench 505, and a first cylinder 506. The guide post 501 is fixedly installed on the upper and lower parts of the back surface of the limit plate 401. The linear bearing 502 is slidably installed on the periphery of the upper and lower two guide posts 501. The movable plate 503 is fixedly installed on the surfaces of the upper and lower two linear bearings 502 and is parallel to the limit plate 401. The high-torque reduction motor 504 is fixedly installed on the upper and lower parts of one side surface of the movable plate 503 away from the limit plate 401, and its output shaft movably penetrates through the inside of the movable plate 503 and extends to the periphery of its front part. The hexagonal socket wrench 505 is fixedly installed at the end parts of the output shafts of the upper and lower two high-torque reduction motors 504, and its center is concentric with the center of the sunk groove 403. The diameter of the hexagonal socket wrench 505 is smaller than the diameter of the sunk groove 403. The first cylinder 506 is vertically distributed and fixedly installed on one side surface of the flipping frame 302 close to the limit plate 401, and the end part of its output rod is fixedly connected to the back surface of the movable plate 503. The maximum distance between the left and right two elastic plastic strips 406 is smaller than the inner diameter of the hexagonal socket wrench 505. The center distance between the upper and lower two hexagonal socket wrenches 505 and the center distance between the left and right two hexagonal socket wrenches 505 are both adapted to the upper and lower hole distances and the left and right hole distances of the photovoltaic panel bolt assembly holes to be installed.

[0065] Specifically, by placing the nut of the installation bolt inside the four hexagonal socket wrenches 505, making the threaded part of the installation bolt penetrate through the sunk groove 403, driving the hexagonal socket wrench 505 to rotate through the output shaft of the high-torque reduction motor 504, further driving the installation bolt located inside the hexagonal socket wrench 505 to rotate together. At the same time, the output rod of the first cylinder 506 pushes the movable plate 503 to move towards the limit plate 401, further driving the high-torque reduction motor 504 and the hexagonal socket wrench 505 to move together, providing the screwing-in effect of the hexagonal socket wrench 505, so that the installation bolt is screwed into the threaded hole on the fixing frame, and the photovoltaic panel is locked on the top of the fixing frame.

[0066] When a photovoltaic panel automatic installation device of this solution is working, the whole device is supported by four casters arranged at the bottom of the base 100 and provides a moving function to move this device to the photovoltaic installation position;

[0067] The worker places the nuts of the four mounting bolts inside the four hexagonal socket wrenches 505, so that the threaded parts of the mounting bolts penetrate through the sinking grooves 403. Subsequently, the second cylinder 4010 is started, and the L-shaped metal block 409 is pushed upward by the output rod of the second cylinder 4010, thereby driving the push bar 408 to move upward. The upward movement of the push bar 408 drives the upper and lower metal pressing plates 407 to move upward together, causing the tops of the two elastic plastic pressing strips 406 hinged to the push bar 408 to move upward, resulting in the reduction of the arcs of the two elastic plastic pressing strips 406 and their gradual approach to the middle, limiting the nuts of the mounting bolts inside the hexagonal socket wrenches 505. At the same time, the left and right elastic plastic pressing strips 406 clamp the outer wall of the threaded part of the mounting bolt to prevent the bolt from shaking, so as to better engage with the threaded holes on the fixing frame during the subsequent installation process, and also prevent the mounting bolt from falling out of the hexagonal socket wrench 505. Subsequently, the worker places the photovoltaic panel on the front of the photovoltaic panel loading component 300, and adsorbs the photovoltaic panel through multiple suction cups 304. Moreover, it is necessary to adjust the position of the photovoltaic panel to be centered with the front of the flipping frame 302 to ensure that the mounting holes at the four corners of the photovoltaic panel are located in front of the four sinking grooves 403;

[0068] Then, the square tube frame 301 is pushed upward by the lifting device 200 to move, and the upward movement of the square tube frame 301 drives the photovoltaic panel feeding component 300, the bolt limiting component 400 and the bolt tightening component 500 to move upward as a whole, and the photovoltaic panel adsorbed by the multiple suction cups 304 is lifted upward to the installation height, and then the pushing block 305 is pushed to move by the output rod of the electric cylinder 306, so that the photovoltaic panel feeding component 300, the bolt limiting component 400, the bolt tightening component 500 and the adsorbed photovoltaic panel are rotated forward along the top of the square tube frame 301 as a whole, until the angle of the photovoltaic panel matches the inclination angle of the fixing frame, so that the bottom of the photovoltaic panel is against the top of the fixing frame, and the electric cylinder 306 is closed, and the bolts inside the four hexagonal socket wrenches 505 just correspond to the positions of the four threaded holes on the top of the fixing frame, and then, the hexagonal socket wrench 505 is driven to rotate by the output shaft of the high-torque reduction motor 504, further driving the hexagonal socket wrench 505 located at the The mounting bolts inside the sleeve wrench 505 rotate together. At the same time, the output rod of the No. 1 cylinder 506 pushes the movable plate 503 to move in the direction of the limit plate 401, further driving the high-torque reduction motor 504 and the hexagonal socket wrench 505 to move together, providing the hexagonal socket wrench 505 with a screw-in effect, so that the mounting bolts are screwed into the threaded holes on the fixing frame. After the mounting bolts are screwed into the threaded holes, the output rod of the No. 2 cylinder 4010 pulls the L-shaped metal block 409 downward to move, further driving the push bar 408 to move downward together. The downward movement of the push bar 408 drives the upper and lower metal pressure plates 407 to move together, exerting downward pressure on the top of the left and right elastic plastic pressure strips 406, causing the left and right elastic plastic pressure strips 406 to be stretched open, making it convenient for the nut part of the mounting bolt to pass through the inside of the countersunk groove 403 and the circular hole 402, locking the photovoltaic panel on the top of the fixing frame, thus completing the installation of the photovoltaic panel.

[0069] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
