Description

Technical Field

[0001] The utility model relates to a system, in particular to a prevention and control warning system applied to a photovoltaic unattended intelligent power station. Background Art

[0002] Photovoltaic power stations are a new type of power generation technology that has emerged in recent years. They receive sunlight through the installation of photovoltaic panels and perform energy conversion.

[0003] Photovoltaic power stations are usually built in open and sunny areas. Due to their large floor area, most of them adopt an unattended mode. That is, by setting up dome camera assemblies at the predetermined monitoring points of the power station and connecting the monitoring information of each dome camera assembly to the central control room, intelligent prevention and control warning of the entire power station can be realized in the central control room.

[0004] For the dome camera assembly, it includes a fixedly arranged base and a dome camera body cooperatively installed on the base. The dome camera body includes a spherical camera and supporting electronic components. During installation, two people cooperate to operate. That is, one person holds the dome camera body and aligns the dome camera body with the base, and then another person installs the fixing bolts to fix the dome camera body on the base. Since the dome camera body and the base are in rigid contact, the sealing performance of the base cavity accommodating the electronic components is poor, and water vapor is likely to enter in bad rainy weather, resulting in component failures and affecting the safe operation of the entire power station. Summary of the Utility Model

[0005] Aiming at the drawbacks of the prior art, the utility model provides a prevention and control warning system applied to a photovoltaic unattended intelligent power station.

[0006] The prevention and control warning system applied to a photovoltaic unattended intelligent power station described in the utility model includes a plurality of dome camera assemblies arranged at predetermined monitoring points. The dome camera assembly includes a base and a dome camera body cooperatively installed on the base. The base includes an inverted fixed bowl cover. The inner wall of the lower edge of the fixed bowl cover is provided with clamping protrusions at intervals along the circumferential direction. An elastic sealing ring with an inner concave card slot is arranged outside the clamping protrusions.

[0007] Wedge-shaped top pieces are arranged at intervals along the circumferential direction on the installation part of the upper edge of the dome camera body. An elastic sealing ring with convex ribs is arranged outside the wedge-shaped top pieces.

[0008] When the dome camera body is installed on the base, the wedge-shaped top pieces are jacked up by the clamping protrusions so that the elastic sealing ring is pressed against the elastic sealing ring, and the convex ribs are clamped into the inner concave card slot.

[0009] In the prevention and control warning system applied to the photovoltaic unmanned intelligent power station described in the present utility model, a turned-out skirt is provided at the lower edge of the fixed bowl cover, and the elastic sealing ring is arranged at the inner edge of the skirt.

[0010] In the prevention and control warning system applied to the photovoltaic unmanned intelligent power station described in the present utility model, by providing a matching clamping protrusion and a wedge-shaped top piece, an operator can complete the installation of the ball machine body alone. Moreover, during the installation process, the gap between the ball machine body and the base is sealed by the compressed elastic sealing ring and elastic sealing ring, so that the electronic components in the base cavity will not be eroded by water vapor, ensuring the safe operation of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0018] As Figure 1 shown, the prevention and control warning system applied to the photovoltaic unmanned intelligent power station described in the present utility model includes a plurality of ball machine camera assemblies arranged at predetermined monitoring points (such as Figure 1The PTZ camera assemblies 1#,..., N#) among them, the video surveillance signals of these PTZ camera assemblies are connected to the central control room, so as to facilitate the monitoring personnel to view the operation status of the entire power station on the monitoring large screen in the central control room, thereby realizing unattended operation and intelligent early warning and prevention and control of the power station.

[0019] Such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, in the prevention and control early warning system applied to the unattended intelligent photovoltaic power station of the present invention, the PTZ camera assembly specifically includes a base 2 and a PTZ camera body 3 cooperatively installed on the base 2, and the base 2 is fixed on a support by a hanging rod 1. The base 2 includes an inverted fixed bowl cover 20 (in the shape of an inverted bowl), and clamping protrusions 22 are arranged at intervals along the circumferential direction on the inner wall of the lower edge of the fixed bowl cover 20. An elastic sealing ring 21 with an inner concave card slot 211 is further arranged outside the clamping protrusions 22 (that is, in the direction close to the lower edge of the fixed bowl cover 20). On the installation part 30 on the upper edge of the PTZ camera body 3, wedge-shaped top parts 32 are arranged at intervals along the circumferential direction. An elastic sealing ring 31 with a convex rib 311 is arranged on the outer ring of the wedge-shaped top part 32, and the elastic sealing ring 31 is supported by a support platform 310 protruding from the lower end of the installation part 30. It should be noted here that the interval distance between the clamping protrusions 22 should be such that the wedge-shaped top part 32 can be inserted from the interval space between the two clamping protrusions 22. At the same time, the interval distance between the wedge-shaped top parts 32 should be such that the clamping protrusions 22 can be inserted from the interval space between the two wedge-shaped top parts 32. The lower end surface of the wedge-shaped top part 32 is an inclined surface. In this way, when the PTZ camera body 3 is installed on the base 2, the wedge-shaped top parts 32 and the clamping protrusions 22 are staggered from each other (such as Figure 5 shown state), so that the wedge-shaped top part 32 can pass through the clamping protrusion 22 from the interval space between the clamping protrusions 22. Then, rotate the PTZ camera body 3 according to the inclination direction of the lower end surface of the wedge-shaped top part 32. Then, as the lower end surface of the wedge-shaped top part 32 is lifted by the clamping protrusion 22 (such as Figure 6 shown state), the PTZ camera body 3 as a whole is lifted and moved towards the base 2. At the same time, the elastic sealing ring 31 moves towards the elastic sealing ring 21 and presses closely against the elastic sealing ring 21, and the convex rib 311 is clamped into the inner concave card slot 211 (from the Figure 3 state switches to Figure 4 shown state), thereby realizing the installation of the PTZ camera body 3 on the base 2. Further, after the PTZ camera body 3 rotates in place, bolts can also be passed through the fixed bowl cover 20 and the installation part 30 at the same time to relatively position the PTZ camera body 3 and the base 2 so as not to cause displacement.

[0020] In the prevention and control early warning system applied to the photovoltaic unattended intelligent power station described in the present utility model, by providing the matching clamping protrusions 22 and wedge-shaped top pieces 32, when installing the ball machine body 3, only align the ball machine body 3 with the base 2, insert and rotate it, and no other person's assistance is required. One person can complete the installation of the ball machine body 3. Moreover, during the installation process, the gaps between the ball machine body 3 and the base 2 are sealed by the compressed elastic sealing rings 21 and elastic sealing rings 31, which also prevents the electronic components in the base cavity from being eroded by water vapor, ensuring the safe operation of the equipment.

[0021] In the prevention and control early warning system applied to the photovoltaic unattended intelligent power station described in the present utility model, the lower edge of the fixed bowl cover 20 can also be provided with an outwardly turned skirt 201, and the elastic sealing ring 21 is arranged on the inner edge of the skirt 201. The outwardly turned skirt 201 can not only protect the elastic sealing ring 21 from being damaged by rain, sunlight and other bad weather, but also expand the sliding radius of rainwater from the outer wall of the fixed bowl cover 20, preventing the rainwater from sliding onto the ball machine body 3 and affecting the shooting of the ball machine camera. Further, a plurality of flexible spacer rings 210 can be arranged on the inclined wall surface of the concave clamping groove 211. When the convex rib 311 is inserted into the concave clamping groove 211, the flexible spacer rings 210 are squeezed and deformed to fill the gap between the elastic sealing ring 21 and the elastic sealing ring 31, thereby enhancing the sealing effect between the elastic sealing ring 21 and the elastic sealing ring 31.

[0022] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, other modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated and described examples here.
