Description

Technical Field

[0001] This invention relates to the field of photovoltaic grid-connected switchgear assembly technology, specifically to assembly equipment for grid-connected switchgear based on photovoltaic energy storage. Background Technology

[0002] A photovoltaic grid-connected switchgear, also known as a photovoltaic switch cabinet, is a specialized electrical device used to connect a photovoltaic power generation system to the power grid. In the entire photovoltaic power generation system, starting from the photovoltaic panels absorbing solar energy to generate direct current (DC), after the inverter converts the DC to alternating current (AC), the photovoltaic grid-connected switchgear takes over the "baton," responsible for a series of subsequent key operations to connect with the grid, ensuring that the power can be smoothly integrated into the grid and realizing the value of photovoltaic power generation.

[0003] The switch cabinet contains electrical components such as circuit breakers, transformers, disconnectors, and arc protection devices. These components need to be connected by wiring, and the wiring usually needs to be organized using the cable trays and cable clips inside the cabinet. Therefore, when assembling the switch cabinet, the outer shell of the cabinet is installed last. The electrical components need to be installed on the mounting plate of the cabinet frame first, then the wiring is connected, the reserved wiring is installed, and then the outer shell of the cabinet is assembled.

[0004] However, during this process, due to the complexity of the wiring and the fact that the wiring needs to pass through multiple components in different locations and may also need to bypass the internal frame of the cabinet, it is necessary to frequently rotate and move around the cabinet manually to install the components and wiring. This is inconvenient to operate, and when there are many wires, the wiring is prone to become messy. It is also necessary to sort out the wiring while it is being run, making it impossible to accurately position the wiring. Summary of the Invention

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-13 An embodiment of the present invention provides an assembly device for a grid-connected switchgear based on photovoltaic energy storage, comprising a base 1, with spherical rollers 2 mounted in a circular array at the lower end of the base 1, and four sets of support seats 10 mounted on the outer wall of the base 1 via a sliding assembly. A fixing assembly for clamping and positioning the switchgear is provided on the inner side of the support seat 10, a sleeve rod 17 is fixedly connected to the upper end of the support seat 10, and a sliding rod 18 is slidably inserted into the sleeve rod 17. A locking assembly is provided on the lower side of the sliding rod 18, a through hole 24 is horizontally opened on the upper side of the sliding rod 18, and a connecting rod 25 is slidably inserted into the through hole 24. A limiting assembly for limiting the rotation angle of the connecting rod 25 is provided in the through hole 24, a handle 26 is fixedly connected to the outer end of the connecting rod 25, a main clamping bar 34 is fixedly connected to the inner end of the connecting rod 25, and a secondary clamping bar 35 is provided on the upper side of the main clamping bar 34 via a spacing adjustment assembly. An adhesive strip 36 for clamping the connecting wires inside the switchgear is provided on the opposite side of the main clamping bar 34 and the secondary clamping bar 35.

[0038] As a preferred embodiment of this example, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the sliding assembly includes a slide rail 3 disposed on the upper side of the base 1, and a slider 4 is slidably disposed on the slide rail 3. The slider 4 is fixedly disposed at the lower end of the support base 10. Ball bearings 5 ​​are installed on the inner walls of the upper and lower sides of the slider 4. Guide rails adapted to the ball bearings 5 ​​are opened at the upper and lower ends of the slider 4. A locking assembly is provided on the outer wall of the slider 4.

[0039] The slider 4 has a circular arc cross-section, and the slide rail 3 has a T-shaped longitudinal section. The inner cavity shape of the slider 4 is adapted to the shape of the slide rail 3, so that the slider 4 cannot be naturally detached from the slide rail 3. The ball bearing 5 is used to reduce the friction when the slider 4 slides and increase the smoothness of movement. In this way, the support base 10 and the above components can make a circular displacement along the base 1, which facilitates the assembly operation of the switch cabinet.

[0040] As a preferred embodiment of this example, Figure 4 , Figure 5 and Figure 6As shown, the locking assembly includes a rotating base 6 rotatably mounted on the lower side of the outer wall of the slider 4, and a connecting base 7 is fixedly connected to the lower end of the rotating base 6. A locking block 8 is provided on the surface of the connecting base 7 near the base 1, and the outer wall of the base 1 is provided with a ring array of slots 9 that are adapted to the locking block 8.

[0041] The outer surface of the locking block 8 is arc-shaped, allowing it to be easily aligned with and locked into the slot 9. Once inserted into the slot 9, the locking block 8 restricts the displacement of the slider 4, thus achieving a locking effect. The switch can be operated simply by rotating the rotating base 6 up and down, making it simple and convenient.

[0042] As a preferred embodiment of this example, Figure 5 and Figure 7 As shown, the fixing component includes a screw sleeve 11 fixedly disposed in the middle position of the support base 10, and a screw rod 12 is inserted into the screw sleeve 11 by a threaded connection. A throttle 13 is fixedly disposed on the outer end of the screw rod 12, and a connecting block 14 is rotatably sleeved on the inner end of the screw rod 12. A clamping plate 15 is horizontally rotatably mounted on the connecting block 14, and an anti-slip pad 16 is glued to the surface of the clamping plate 15.

[0043] The clamping plate 15 is parallel to the base 1, and the edges and corners of the clamping plate 15 are rounded. This structure is used to adjust the position of the clamping plate 15 on the upper surface of the base 1 by rotating the handle 13. By adjusting the four sets of handles 13 in sequence, the four sets of clamping plates 15 can be clamped and fixed to the bottom of the switch cabinet. The clamping plate 15 can rotate horizontally on the connecting block 14, so it can fit well against the outer wall of the switch cabinet, thereby maintaining the clamping fit and stability.

[0044] As a preferred embodiment of this example, Figure 9 and Figure 10 As shown, the locking assembly includes a handle 19 fixedly arranged laterally on the outer wall of the slide bar 18, a slide sleeve 20 slidably sleeved on the handle 19, and a protrusion 21 fixedly arranged on the upper wall of the slide sleeve 20. A locking tooth 22 is symmetrically arranged on the side of the slide sleeve 20 near the sleeve bar 17, and the end corner of the locking tooth 22 is rounded. The outer walls on both sides of the sleeve bar 17 are provided with locking teeth 23 with a spacing that matches the end size of the locking tooth 22.

[0045] The handle 19 is square with rounded corners. The sliding sleeve 20 is fitted onto the handle 19 and can only slide laterally, not rotate. The protrusion 21 facilitates sliding of the sliding sleeve 20 by pushing it with the thumb. The rounded corner of the end of the locking tooth 22 is inserted into the gap of the locking tooth 23. When the locking tooth 22 is inserted into the locking tooth 23, the height of the sliding rod 18 and the sleeve 17 can be locked, which makes it easy to adjust the height of the sliding rod 18 during operation, thereby changing the height of the main clamping bar 34 and the secondary clamping bar 35 to adapt to different cable management needs.

[0046] As a preferred embodiment of this example, Figure 11 As shown, the limiting component includes movable grooves 27 that are opened on the inner walls of the upper and lower sides of the through hole 24. A limiting block 28 is movably installed at the opening of the movable groove 27. A limiting spring 29 is longitudinally arranged in the movable groove 27, and the limiting spring 29 abuts against the limiting block 28. The end of the limiting block 28 is hemispherical. The surface of the connecting rod 25 is arrayed with limiting grooves 30 that are adapted to the end of the limiting block 28.

[0047] The limiting groove 30 has four sets, each set at a 90-degree angle. This structure is used to limit the angle of the connecting rod 25 by embedding two sets of limiting blocks 28 into the upper and lower sets of opposing limiting grooves 30, preventing it from rotating naturally. During adjustment, the connecting rod 25 is actively rotated by the handle 26, causing the connecting rod 25 to be pressed against the hemispherical end face of the limiting block 28, which is then squeezed into the movable groove 27 and compresses the limiting spring 29. After the connecting rod 25 rotates 90 degrees, the limiting block 28 will align with the limiting groove 30, and the compressed limiting spring 29 will push the limiting block 28 into the limiting groove 30 through its elastic force, again limiting the rotation of the connecting rod 25. In this way, the main clamping bar 34 can be changed to be horizontal or vertical, so as to adjust it according to the wiring requirements when assembling the switch cabinet.

[0048] As a preferred embodiment of this example, Figure 11 As shown, a threaded groove 31 is provided at the center of the upper end of the slide bar 18, which is connected to the movable groove 27. An external threaded head 32 is connected to the threaded groove 31 by a thread. The lower end of the external threaded head 32 abuts against the upper end of the upper limiting spring 29. An internal hexagonal groove 33 is provided on the upper surface of the external threaded head 32.

[0049] The external threaded head 32 can be rotated by inserting a hex wrench into the internal hexagonal groove 33, so that it can engage with the threaded groove 31 and move up and down. This structure is used to adjust the height of the external threaded head 32, thereby changing the squeezing force of the external threaded head 32 on the upper end of the limiting spring 29, so that the force applied by the limiting spring 29 to the limiting block 28 is changed. Thus, the spring switch force of the upper limiting block 28 can be adjusted according to the needs to adapt to different operating requirements.

[0050] As a preferred embodiment of this example, Figure 12 and Figure 13 As shown, the longitudinal section of the rubber strip 36 is triangular, and the surface of the rubber strip 36 away from the connecting rod 25 is an inclined surface. Multiple sets of rubber strips 36 are equidistantly arranged on the opposite side surfaces of the main clamping strip 34 and the auxiliary clamping strip 35.

[0051] This structure is used to clamp the passing wires by the rubber strips 36 opposite to the main clamping bar 34 and the secondary clamping bar 35. The friction between the rubber materials when they come into contact with each other applies a fixing effect to the wires. When the wires are pulled by sufficient force, they can also be pulled out from the rubber strips 36, thereby avoiding damage to the connection between the wires and electrical components caused by accidental pulling. The inclined surface design makes it easy for the wires to be inserted from this side.

[0052] As a preferred embodiment of this example, Figure 12 and Figure 13 As shown, the spacing adjustment assembly includes seat blocks 37 symmetrically hinged at both ends of the main clamping bar 34 and the secondary clamping bar 35. Nuts 38 are fixedly installed on the seat blocks 37 at both ends of the secondary clamping bar 35. Screws 39 are threadedly inserted into the nuts 38, and the lower end of the screws 39 is rotatably installed on the seat block 37 at the end of the main clamping bar 34. A knob 40 is fixedly connected to the upper end of the screws 39.

[0053] This structure is used to rotate the screw 39 and engage the nut 38 by adjusting two sets of knobs 40, thereby changing the distance between the main clamping bar 34 and the auxiliary clamping bar 35. This changes the distance between the rubber strips 36 on the opposite side of the main clamping bar 34 and the auxiliary clamping bar 35 to accommodate wires of different thicknesses. The fixing force, effect, and applicable range can all be manually adjusted.

[0054] Working principle: In practical use, the four sets of support seats 10 are first moved to one side, such as... Figure 3 As shown, the switch cabinet to be assembled is then placed at the upper center of the base 1. Then, the four sets of support seats 10 are moved so that the slider 4 slides along the slide rail 3 on the outside of the base 1 via the ball bearing 5. After the four sets of support seats 10 are placed on the four sides of the switch cabinet, the rotating seat 6 is rotated downward so that the connecting seat 7 drives the locking block 8 to be inserted into the corresponding slot 9, thereby locking the position of the support seat 10.

[0055] Then rotate the handle 13, causing the screw 12 to rotate and engage with the screw sleeve 11, driving the clamping plate 15 to move towards the switch cabinet and abut against it. After operating the four sets of handles 13 in sequence, the four sets of clamping plates 15 will abut against the four sides of the switch cabinet to achieve clamping and positioning. Then, the electrical components can be installed in the switch cabinet, and the cables can be connected. After all the cables are connected, they need to be routed and organized uniformly before being connected to other components. During this process, the cable ends can be inserted into the rubber strip 36 between the main clamping bar 34 and the auxiliary clamping bar 35, and the cables can be straightened by pulling them out. Multiple sets of cables can be clamped side by side in the rubber strip 36 between the main clamping bar 34 and the auxiliary clamping bar 35.

[0056] As shown in the figure, the distance between the main clamping bar 34 and the auxiliary clamping bar 35 can be adjusted according to the thickness of different cables. The knob 40 can be rotated to make the screw 39 rotate and engage with the nut 38, thereby changing the distance between the upper and lower sets of seat blocks 37, which in turn changes the distance between the main clamping bar 34 and the auxiliary clamping bar 35, and consequently changes the distance between the rubber strips 36.

[0057] Alternatively, by holding the handle 26 and pulling the connecting rod 25 horizontally, it can be slid within the through hole 24, thereby changing the position of the main clamping bar 34 and the secondary clamping bar 35. The handle 26 can also be rotated, causing the connecting rod 25 to rotate and press the limiting block 28, causing it to retract into the movable groove 27 and compress the limiting spring 29. After the connecting rod 25 is rotated 90 degrees, the limited spring 29, which is in a compressed state, will use its elasticity to drive the limiting block 28 to reset and embed into the limiting groove 30 to limit it. In this way, the position of the main clamping bar 34 and the secondary clamping bar 35 can be manually adjusted to be vertical or horizontal to adapt to different cable management needs.

[0058] Meanwhile, if it is necessary to adjust the height of the main clamping bar 34, the protrusion 21 can be pulled to make the sliding sleeve 20 slide along the handle 19 and drive the locking tooth 22 to disengage from the locking tooth 23. Then the sliding rod 18 can be extended and retracted within the sleeve rod 17 to change the height of the through hole 24. After the height is about right, the locking tooth 22 can be re-aligned with the gap of the locking tooth 23 and inserted to lock the height. The overall operation of the device is simple and convenient.
