[0002] Photovoltaic power stations are power generation facilities that use photovoltaic (solar) panels to convert solar energy into electrical energy. Photovoltaic power stations convert sunlight into direct current by installing a large number of photovoltaic modules (solar panels), and convert direct current into alternating current through inverters, which are finally incorporated into the power grid or supplied to users. Photovoltaic power stations, as a renewable energy power generation method, are clean, environmentally friendly, and sustainable. Photovoltaic intelligent box transformer measurement and control devices are used in photovoltaic power stations to measure and control photovoltaic power stations. In order to achieve remote management and monitoring of basic operating information of solar photovoltaic box transformers, it is necessary to install an intelligent monitoring system. Through the intelligent monitoring system of solar photovoltaic box transformers, important parameters in the photovoltaic box transformer measurement and control device are collected and monitored, and the collected signals are synchronously transmitted to the remote monitor through the network, so that the operation of the box transformer can be grasped in real time.

[0015] S1, during installation, align the installation plate 1 with the measurement and control box body and insert the L-shaped rod into the slot. Align the L-shaped rod with the slot and insert it to prevent installation deviation. At the same time, the card block 1 and the sliding plate will be inserted into the card slot. Turn the pull handle to rotate the connecting rod 1 and the gear 1. The gear 1 will mesh with the toothed plate, driving the two sliding plates to move relatively apart. At the same time, the sliding plate will drive the card block 1 and the card block 2 to move relatively apart, so that the card block 2 is inserted into the card slot for quick installation. When disassembling, the pull handle can be reversed and driven at the same time. The connecting rod 1 and the gear 1 are reversed to reset the sliding plate, the card block 1 and the card block 2.

The operation is cumbersome, time-consuming and labor-intensive.

[0016] S2, after the installation of the mounting plate 1 and the measurement and control box is completed, continue to rotate the handle, which will cause the gear 1 to continue to rotate.

[0017] S3, when gear one rotates, it will drive connecting rod two to rotate, and the rotation of connecting rod two will drive bevel gear one to mesh with bevel gear two, so that connecting rod three will drive gear two to rotate, and the rotation of gear two will mesh with the tooth groove, so that the output rod will slide forward in the sleeve, and the movement of the output rod will drive the wire clamping plate to move, and the wires will be gathered and clamped through the wire clamping plate to avoid the internal connecting wires being unable to be gathered together and appearing messy during installation. At the same time, the messy connecting wires increase the risk of electromagnetic interference and affect the signal transmission problem. When the detection and control box needs to be disassembled, reverse the handle to drive connecting rod two to reverse, and at the same time, it will drive bevel gear one, connecting rod three, bevel gear two and gear two to reverse, reset the output rod and the wire clamping plate, and release the clamping state of the connecting wire for easy maintenance.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention avoids the problem of using a screwdriver to unscrew the bolts one by one during each maintenance, which is cumbersome to operate. The rotating handle rotates the connecting rod one and the gear one, and the gear one meshes with the toothed plate, driving the two sliding plates to move relatively apart. At the same time, the sliding plate drives the clamping block one and the clamping block two to move relatively apart, so that the clamping block two is clamped into the clamping groove for quick installation. When disassembling, the rotating handle can be reversed and driven at the same time, and the connecting rod one and the gear one are reversed to reset the sliding plate, the clamping block one and the clamping block two, and then the mounting plate one is pulled backwards by the rotating handle for disassembly, thereby avoiding the need to use a screwdriver or a wrench to unscrew the bolts one by one during each maintenance, and then tighten the bolts one by one after the maintenance is completed, which is cumbersome, time-consuming and labor-intensive.

[0020] The present invention arranges the cooperation of the connecting rod 2 and the gear 2 and other structures to avoid the problem that the internal connecting wires cannot be gathered together and appear messy during installation, and the problem that the model is affected. The connecting rod 2 rotates to drive the bevel gear 1 to mesh with the bevel gear 2, so that the connecting rod 3 drives the gear 2 to rotate. The rotation of the gear 2 will mesh with the tooth groove to make the output rod slide forward in the sleeve. The movement of the output rod will drive the wire clamping plate to move, and the wires are gathered and clamped by the wire clamping plate, so that the internal connecting wires cannot be gathered together and appear messy during installation. At the same time, the messy connecting wires increase the risk of electromagnetic interference and affect signal transmission. BRIEF DESCRIPTION OF THE DRAWINGS

A photovoltaic power station measurement and control method, applied to the photovoltaic power station measurement and control device according to claims 1-9, characterized in that: The steps are as follows: S1, during installation, align the installation plate 1 (2) with the measurement and control box (1) and insert the L-shaped rod (19) into the slot (4). Align the L-shaped rod (19) with the slot (4) to prevent installation deviation. At the same time, the block 1 (11) and the sliding plate (10) will be inserted into the slot (3). Turn the handle (7) to rotate the connecting rod 1 (8) and the gear 1 (9). The gear 1 (9) will mesh with the toothed plate (13), driving the two sliding plates (1 0) are relatively far apart, and at the same time, the sliding plate (10) drives the card block 1 (11) and the card block 2 (12) to be relatively far apart, so that the card block 2 (12) is inserted into the card slot (3) for quick installation. When disassembling, the pull handle (7) can be reversed to drive the connecting rod 1 (8) and the gear 1 (9) to reverse and reset the sliding plate (10), the card block 1 (11) and the card block 2 (12), and then the installation plate 1 (2) is pulled backward by rotating the pull handle (7) for disassembly; S2, when the installation plate 1 (2) and the measurement and control box (1) are installed, the rotating handle (7) is continuously rotated, which causes the gear 1 (9) to continue to rotate. When the gear 1 (9) rotates and contacts the tooth block (17), the tooth block (17) is driven to slide in the compression groove (14), and the spring (16) is compressed at the same time, so that the gear 1 (9) continues to rotate and the sliding plate (10) does not move with the rotation of the gear 1 (9); S3, when the gear 1 (9) rotates, it drives the connecting rod 2 (18) to rotate, and the connecting rod 2 (18) drives the bevel gear 1 (20) to mesh with the bevel gear 2 (22), so that the connecting rod 3 (21) drives the gear 2 (24) to rotate, and the gear 2 (24) rotates to mesh with the tooth groove (27) so that the output rod (26) slides forward in the sleeve (25), and the output rod (26) moves to drive the clamping plate (28) to move, and the wire is gathered and clamped by the clamping plate (28), so as to avoid the internal connection during installation. The wires (31) cannot be gathered together and appear messy. At the same time, the messy connecting wires (31) increase the risk of electromagnetic interference and affect the signal transmission. When the detection and control box (1) needs to be disassembled, the pull handle (7) is reversed to drive the connecting rod 2 (18) to reverse, and at the same time, it will drive the bevel gear 1 (20), the connecting rod 3 (21), the bevel gear 2 (22) and the gear 2 (24) to reverse, reset the output rod (26) and the wire clamping plate (28), release the clamping state of the connecting wire (31), and facilitate maintenance.
