[0034] 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.

[0035] Embodiment 1

[0036] As Figure 1Among them, it includes a device main body 1; a protective housing 3 is fixed to the side of the device main body 1 through a fixing member 2. Locking components 6 are provided on two opposite side walls of the protective housing 3. A locking disc 5 is arranged between the two locking components 6. A connecting shaft 4 is fixedly connected to the side surface of the locking disc 5, and the end of the connecting shaft 4 penetrates through the protective housing 3 and is connected to the pitching axis of the device main body 1. By using two groups of locking components 6 to squeeze the locking disc 5, the locking disc 5 is fixed, and then the pitching axis of the device main body 1 is locked and fixed through the connecting shaft 4.

[0037] As Figures 2 - 4 Among them, the locking component 6 includes a fixing plate 61. A plurality of damping rods 62 are fixedly connected to the side surface of the fixing plate 61. The other ends of the plurality of damping rods 62 are commonly fixedly connected to a pushing plate 64. A first spring 63 is sleeved on each of the plurality of damping rods 62. A locking block 66 is arranged on the side of the pushing plate 64 opposite to the damping rods 62, and the side surface of the locking block 66 faces the locking disc 5. An adsorption plate 614 is fixedly connected to the side surface of the pushing plate 64 facing the fixing plate 61. An electromagnetic plate 613 is fixedly connected to the side surface of the fixing plate 61 facing the pushing plate 64. As Figure 1 Among them, an electromagnetic control module 7 for controlling the electromagnetic plate 613 to generate magnetic force is installed on the outer side of the protective housing 3. As Figure 3 Among them, the first spring 63 is located between the fixing plate 61 and the pushing plate 64. After the electromagnetic plate 613 generates magnetic force, the adsorption plate 614 can be adsorbed on its side surface. In the initial state, the first spring 63 will always push towards the pushing plate 64, so that the locking block 66 on the side surface of the pushing plate 64 can fit on the side surface of the locking disc 5 to lock the locking disc 5. And the electromagnetic control module 7 is used to control the electromagnetic plate 613 to generate magnetic force to adsorb the adsorption plate 614 by the electromagnetic plate 613, so that the pushing plate 64 drives the locking block 66 to move away from the locking disc 5, thereby releasing the locking effect on the locking disc 5.

[0038] During operation, in order to lock the pitching axis of the optoelectronic platform and prevent equipment damage in the non-operating state from affecting normal operation, in this solution, the electromagnetic control module 7 is powered on. When the electromagnetic control module 7 is in the powered state, it will control the electromagnetic plate 613 to generate magnetic force. Under the magnetic adsorption of the electromagnetic plate 613, the adsorption plate 614 will move towards the electromagnetic plate 613 and adsorb on the side of the electromagnetic plate 613. When the adsorption plate 614 moves towards the electromagnetic plate 613, it will drive the pushing plate 64 to move towards the fixing plate 61, and during the movement, it will squeeze the first spring 63 to make it contract, and the damping rod 62 will also contract. As a result, the pushing plate 64 will drive the locking block 66 on its side to move away from the side of the locking disc 5, thereby releasing the locking effect of the two locking components 6 in the protective housing 3 on the locking disc 5. At this time, the pitching axis of the equipment main body 1 can rotate. When the power supply to the electromagnetic control module 7 is removed, the electromagnetic plate 613 will lose its magnetism. At this time, under the action of the first spring 63, the pushing plate 64 will push again towards the locking block 66 on its side and fit on the side of the locking disc 5, thereby locking the locking disc 5 again, and preventing the connecting shaft 4 from rotating, so as to achieve the locking effect of the pitching axis of the photovoltaic platform. By rotating and locking the projection window of the equipment main body 1 within the envelope of its azimuth axis system, protection can be achieved;

[0039] The cooperation achieves the locking effect of the pitching axis of the photovoltaic platform, effectively avoiding damage to the projection window of the equipment in the non-operating state and affecting normal use.

[0040] Embodiment 2

[0041] As Figure 4 and Figure 6 shown in Figure 5 shown in

[0042] As Figure 3 and Figure 6Among them, guide grooves 69 are respectively formed on both sides of the opening of the installation groove 65 on the side surface of the pushing plate 64. Sliders 610 are slidably arranged in the guide grooves 69, and baffles 611 are fixedly connected to the sliders 610. Second springs 612 are arranged in the guide grooves 69, and the two second springs 612 are located outside the two sliders 610. The baffle 611 can be slidably arranged outside the opening of the installation groove 65 through the slider 610, and the locking block 66 is restricted and fixed in the installation groove 65. In the initial state, the second springs 612 located on both sides of the opening of the installation groove 65 will always push the sliders 610 inward, so that the two sliders 610 slide inward in the guide grooves 69, so that the baffle 611 moves outside the opening of the installation groove 65, and then the locking block 66 is blocked and limited.

[0043] As Figure 7 Among them, a maintenance opening 8 is formed on the side surface of the protective housing 3, a closing door 9 is rotatably arranged at the opening edge of the maintenance opening 8, and the closing door 9 can be locked outside the opening of the maintenance opening 8. Through the arranged closing door 9, it is convenient to maintain the components in the protective housing 3.

[0044] During operation, in this solution, the locking block will be worn during the locking process of the locking disc. Excessive wear will affect the locking effect. In order to ensure the locking effect, the locking block needs to be replaced in time. In this solution, the locking block 66 is locked by the baffle 611 so that it can be fixed in the installation groove 65. When replacing, open the closing door 9, and then push the baffle 611 to both sides. The two baffles 611 drive the two sliders 610 to move outward respectively, and squeeze the two second springs 612 to contract during the movement. When the two baffles 611 move away from the opening of the installation groove 65, the locking block 66 can be taken out of the installation groove 65. When reinstalling, align the locking block 66 between the two baffles 611, and press it in the installation groove 65, so that the locking block 66 squeezes the baffle 611 to both sides, so that the two baffles 611 drive the sliders 610 below them to move outward through the sliders 610 respectively. When the locking block 66 is installed, the ribs 68 on both sides of the locking block 66 are respectively aligned with the rib grooves 67 formed on both sides of the installation groove 65 and installed. After the locking block 66 is installed in place, the baffles 611 located on both sides of the opening of the installation groove 65 will move back to the opening of the installation groove 65 under the action of the second spring 612 to fix the locking block 66.

[0045] The cooperation achieves the function of facilitating the replacement of the locking block, and effectively improves the use convenience of the self-locking device for the pitch axis of the photovoltaic platform in this solution.

What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
