Description

Technical Field

[0001] This application relates to the technical field of photovoltaic equipment, and more specifically, to a cable protection mechanism for photovoltaic power plants. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy and employs special materials such as crystalline silicon panels and electronic components like inverters. It is connected to the power grid and transmits electricity to it. Centralized large-scale grid-connected PV power stations are large-scale PV power stations built by the state in desert areas. The generated electricity is directly fed into the public power grid and connected to the high-voltage transmission system to supply long-distance loads. The PV panels need to transmit the converted electrical energy to batteries via cables. PV power stations have a large number of cables, especially near the batteries, where cables are prone to confusion and tangling.

[0003] Some existing devices (e.g., patent number CN 219268814U, entitled "A Protective Structure for a Photovoltaic Power Station Hub Device") protect the hub device by placing it at the bottom of a buffer box, extending the connecting plate and connecting spring at the bottom of the buffer box into a groove, placing the protective box on top of the base plate, and rotating the fastening bolts to compress and limit the protective box. When the buffer box is impacted, it is cushioned by the first and second rubber pads. Simultaneously, a sliding plate slides within the top groove, compressing the elastic rod and further protecting the buffer box. The contact between the first and second spring balls further protects the buffer box, improving its practicality and application range. However, protecting the hub device requires rotating the fastening bolts to limit the protective box and sliding the sliding plate to compress the elastic rod, again limiting the buffer box. This cumbersome operation reduces installation efficiency. Utility Model Content

A limiting post is provided on the side of the protective plate facing the protective shell. The limiting post cooperates with the fixing structure and is movably disposed within the mounting groove. There is a gap between the two sets of protective plates. The cable passes through the through cavity and is located between the two sets of protective plates.

[0006] In some embodiments, the fixing structure includes a spring, an electromagnet, and a mating post.

[0007] In some embodiments, an iron block is provided on the side of the limiting post facing the electromagnet, and the bottom of the mounting groove has a through hole for the coil of the electromagnet to pass through. The photovoltaic power station cable protection mechanism has a conventional state in which the electromagnet and the iron block are attracted to each other, or a protective state in which the electromagnet and the iron block are separated.

[0008] In some embodiments, the fixing structure further includes a mounting box, a battery, and a control switch. The mounting box is disposed on the protective shell, the battery is disposed inside the mounting box, the battery and the coil are electrically connected, the battery is used to supply power to the electromagnet, and the control switch is disposed on the coil and is used to control the opening and closing of the circuit.

[0009] In some embodiments, the fixed structure further includes an infrared transmitter and an infrared receiver, both of which are mounted on the protective housing, are positioned opposite each other, and are electrically connected to a control switch.

[0010] In some embodiments, both sets of protective plates are arc-shaped plates, the two sets of protective plates are arranged opposite each other, and the opposite surfaces of the two sets of protective plates are provided with a rubber layer.

[0028] like Figures 1 to 3 As shown, the embodiment relates to a cable protection mechanism for a photovoltaic power station, including a fixing structure 10 and a protective structure 20. The protective structure 20 includes a protective shell 21 and a protective plate 22. The protective shell 21 has a through cavity, and the inner wall of the through cavity has a mounting groove 211. At least two sets of protective plates 22 are provided, and both sets of protective plates 22 are disposed in the through cavity. The side of the protective plate 22 facing the protective shell 21 has a limiting post 221. The limiting post 221 cooperates with the fixing structure 10 and is movably disposed in the mounting groove 211. There is a gap between the two sets of protective plates 22. The cable passes through the through cavity and is located between the two sets of protective plates 22.

[0029] Using the technical solution of this embodiment, the photovoltaic power station cable protection mechanism includes a fixing structure 10 and a protection structure 20. The protection structure 20 includes a protective shell 21 and a protective plate 22. The protective shell 21 has a through cavity, and the inner wall of the through cavity has a mounting groove 211. At least two sets of protective plates 22 are provided, both sets of which are disposed within the through cavity. Each protective plate 22 has a limiting post 221 on the side facing the protective shell 21. The limiting post 221 cooperates with the fixing structure 10 and is movably disposed within the mounting groove 211. The fixing structure 10 can fix the limiting post 221. There is a gap between the two sets of protective plates 22. This arrangement allows the distance between the two sets of protective plates 22 to be adjusted to accommodate cables of different sizes. The cable passes through the through cavity, and the protective shell 21 provides the first layer of protection for the cable. The cable is located between the two sets of protective plates 22, and clamping the cable can be achieved by adjusting the distance between the protective plates 22. The two sets of protective plates 22 provide the second layer of protection for the cable. The cable only needs to pass through the protective plates 22 to achieve good protection. The technical solution of this embodiment effectively solves the problems of cumbersome operation steps and low installation efficiency in the prior art when protecting cables.

[0030] like Figure 4 As shown, in some embodiments, the fixing structure 10 includes a spring 11, an electromagnet 12, and a mating post 13. The first end of the spring 11 is connected to the bottom of the mounting groove 211, and the second end of the spring 11 is connected to the limiting post 221. The movement of the limiting post 221 compresses the spring 11. The first end of the electromagnet 12 is connected to the bottom of the mounting groove 211, and the second end of the electromagnet 12 is connected to the mating post 13. The spring 11 is sleeved on the circumferential outer side of the electromagnet 12, and the limiting post 221 is movably sleeved inside the mating post 13. As the limiting post 221 moves, it moves closer to and further away from the electromagnet 12.

[0031] like Figure 4 As shown, in some embodiments, an iron block is provided on the side of the limiting post 221 facing the electromagnet 12, and the bottom of the mounting groove 211 has a through hole for the coil of the electromagnet 12 to pass through. The photovoltaic power station cable protection mechanism has a conventional state in which the electromagnet 12 and the iron block are attracted to each other, or a protective state in which the electromagnet 12 and the iron block are detached. In the conventional state, since the electromagnet 12 and the iron block are attracted to each other, the distance between the protective plates 22 is at its maximum, which facilitates the placement of the cable. After the cable is placed, the mechanism is switched to the protective state. At this time, the electromagnet 12 and the iron block are detached, and the limiting post 221 drives the protective plate 22 to move, so that the protective plate 22 and the cable surface are in contact to clamp the cable. Even under the action of external force, the cable can still be protected.

[0032] like Figure 1As shown, in some embodiments, the fixing structure 10 also includes a mounting box 14, a battery, and a control switch. The mounting box 14 is disposed on the protective shell 21, and the battery is disposed inside the mounting box 14. The battery and the coil are electrically connected, and the battery is used to supply power to the electromagnet 12. The control switch is disposed on the coil and is used to control the opening and closing of the circuit, thereby controlling the magnetism of the electromagnet. The operator adjusts the photovoltaic power station cable protection mechanism to the normal state through the control switch, and then places the cable. After placement, the photovoltaic power station cable protection mechanism is adjusted to the protection state. This setting greatly simplifies the operation steps and improves the cable installation efficiency.

[0033] like Figure 1 As shown, in some embodiments, the fixing structure 10 further includes an infrared transmitter 15 and an infrared receiver 16. Both the infrared transmitter 15 and the infrared receiver 16 are mounted on the protective housing 21, positioned opposite each other. The infrared receiver 16 is electrically connected to a control switch. In the normal state, since no cable is placed, the infrared receiver 16 can receive the signal emitted by the infrared transmitter 15. In the protected state, after the cable is placed, it is positioned between the infrared transmitter 15 and the infrared receiver 16, preventing the infrared receiver 16 from receiving the signal from the infrared transmitter 15. At this time, the control switch automatically disconnects the power supply to the electromagnet, achieving automatic clamping of the protective plate 22. The operator only needs to insert the cable during operation, further improving operational efficiency.

[0034] like Figure 3 As shown, in some embodiments, both sets of protective plates 22 are arc-shaped plates, which allows the protective plates 22 to better fit the surface of the cable. The two sets of protective plates 22 are arranged opposite each other, and the opposite surfaces of the two sets of protective plates 22 are provided with a rubber layer. The rubber layer can prevent wear on the surface of the cable when clamping the cable. Both sets of protective plates 22 have limiting posts 221, and the inner wall of the cavity has two sets of mounting grooves 211. The two sets of limiting posts 221 and the two sets of mounting grooves 211 are arranged in a one-to-one correspondence to realize the adjustment of the distance between the two sets of protective plates 22.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the cavity is a cylindrical cavity, which allows the inner wall of the cavity to fit against the protective plate 22. The mounting groove 211 extends in a direction perpendicular to the axis of the cavity, facilitating the movement of the limiting post 221.

[0036] like Figure 1 and Figure 5As shown, in some embodiments, the photovoltaic power station cable protection mechanism further includes an installation structure 30. The installation structure 30 includes an installation plate 31 and a first connecting post 32. The installation plate 31 and the protective shell 21 are connected by the first connecting post 32. The installation plate 31 is a rectangular plate, and there are installation holes at the four corners of the installation plate 31. The position of the installation plate 31 can be fixed by screws, thereby fixing the entire photovoltaic power station cable protection mechanism and making the cable placement more orderly.

[0037] like Figure 1 As shown, in some embodiments, both the fixing structure 10 and the protective structure 20 are multiple sets, with each set of fixing structure 10 and protective structure 20 arranged in a one-to-one correspondence. Each set of protective structure 20 corresponds to a set of cables, and by increasing the number of protective structures 20 and fixing structures 10, protection for multiple sets of cables can be achieved simultaneously. Each set of protective structures 20 includes a protective shell 21, and the mounting structure 30 also includes multiple second connecting posts 33. The multiple protective shells 21 are connected to each other through the second connecting posts 33, thus enabling the entire structure to move during movement.
