Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to an automatic monitoring device for main equipment of a transformer substation. Background Art

[0002] A substation is a complex and sophisticated system. Primary equipment (transformers, circuit breakers, disconnectors, instrument transformers, busbars, lightning arresters, etc.) constitute the "backbone" of energy transmission, directly responsible for the conversion and distribution of electrical energy. Secondary equipment (relay protection devices, safety automation devices, monitoring and data acquisition systems, energy metering systems, etc.) serves as the "brain and nervous system" for control, protection, and monitoring, ensuring the safe, reliable, intelligent, and efficient operation of the primary equipment. Understanding the functions and interrelationships of these devices is fundamental to mastering substation operation and maintenance. Existing substation main equipment is monitored internally by surveillance cameras. Most of these cameras are fixed, with a fixed coverage area that cannot be effectively moved, resulting in high costs and a lack of effective ventilation, which compromises equipment safety. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an automatic monitoring device for the main equipment of the substation, which effectively solves the problem that the monitoring camera is difficult to move and affects ventilation.

[0004] The technical solution to solve the technical problem is: it includes a substation box, a lead screw set in the left and right directions is rotatably connected in the substation box, the lead screw is threadedly connected to a slider, a vertical fixed shaft is fixed at the lower end of the slider, a monitoring camera is installed at the lower end of the fixed shaft, the fixed shaft is rotatably connected to a disc, multiple fans are evenly installed on the disc, an outer gear ring is coaxially fixed on the disc, a bracket is fixed at the front end of the slider, the bracket is rotatably connected to the vertical rotating shaft, and the rotating shaft is coaxially fixed with a gear meshing with the outer gear ring.

[0005] Preferably, the substation box is fixed with guide rails located at the front and rear sides of the lead screw, and the slider slides in the left and right directions along the guide rails.

[0006] Preferably, a first motor is installed on the substation box, and the first motor is coaxially fixedly connected to the lead screw via a reducer.

[0007] Preferably, a second motor is mounted on the bracket, and the second motor is coaxially fixedly connected to the rotating shaft.

[0008] Preferably, a battery is installed on the upper end of the disc, and the battery is electrically connected to the fan.

[0009] Compared with traditional equipment, the present invention has the following advantages: 1) The structure is ingenious. Combined with the screw-nut structure, the left and right movement of the slider, disc and monitoring camera is cleverly controlled by the rotation of the screw. The threaded connection is self-locking, and the monitoring camera can be kept in a suitable position at any time. It has good flexibility and is easy to move the monitoring camera, which increases the monitoring range of the monitoring camera. There is no need for multiple monitoring cameras, which reduces costs; 2) The disc drives multiple fans to move in the left and right directions, and then controls the rotational movement of the disc and multiple fans through gears and outer gear rings, which increases the range of movement of the fans, accelerates the air circulation area, and has a good ventilation effect. It can effectively cool the main equipment of the substation, ensure the safe operation of the equipment, and extend the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 An automatic monitoring device for main equipment of a substation is provided, comprising a substation box body 1, a lead screw 2 arranged in left and right directions is rotatably connected inside the substation box body 1, the lead screw 2 is threadedly connected to a slider 3, a vertical fixed shaft 4 is fixed to the lower end of the slider 3, a monitoring camera 5 is installed at the lower end of the fixed shaft 4, the fixed shaft 4 is rotatably connected to a disc 6, a plurality of fans 7 are evenly installed on the disc 6, an outer gear ring 8 is coaxially fixed to the disc 6, a bracket 9 is fixed to the front end of the slider 3, the bracket 9 is rotatably connected to a vertical rotating shaft 10, and a gear 11 meshing with the outer gear ring 8 is coaxially fixed to the rotating shaft 10.

[0014] In order to ensure the stability of the left-right movement of the slider 3 , the substation box 1 is fixed with guide rails 12 located at the front and rear sides of the lead screw 2 , and the slider 3 slides left and right along the guide rails 12 .

[0015] In order to ensure a suitable rotation speed of the lead screw 2, a first motor 13 is installed on the substation box 1. The first motor 13 is coaxially fixedly connected to the lead screw 2 via a reducer.

[0016] The bracket 9 is provided with a second motor 14 , which is coaxially fixedly connected to the rotating shaft 10 .

[0017] A battery 15 is installed on the upper end of the disc 6 , and the battery 15 is electrically connected to the fan 7 .

[0018] When the present invention is in use, the main equipment of the substation is inside the substation box 1, and the monitoring camera 5 is a rotatable camera. When the main equipment of the substation needs to be monitored, the first motor 13 is started, and the first motor 13 drives the screw 2 to rotate through the reducer, and the screw 2 drives the slider 3 to slide left and right along the guide rail 12, and the slider 3 drives the fixed shaft 4, the disc 6 and the monitoring camera 5 to slide left and right as a whole. The monitoring camera 5 moves left and right inside the substation box 1, thereby increasing the monitoring range of the main equipment of the substation. Combined with the rotation of the monitoring camera 5 itself (rotating camera belongs to the existing technology), it can fully monitor and cover the main equipment of the substation, with good flexibility and easy adjustment. Then turn on the battery 15 and the second motor 14. The battery 15 provides power for the fan 7, and the fan 7 is directed. Multiple fans 7 on the disc 6 blow air downward at the same time. The substation box 1 is provided with ventilation holes, which can enable the outside air to flow with the air inside the substation box 1 to achieve heat exchange, which can not only cool the surveillance camera 5, but also cool the main equipment of the substation. The second motor 14 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the gear 11 to rotate coaxially. The gear 11 drives the outer ring gear 8 to rotate, and the outer ring gear 8 drives the disc 6 to rotate. The disc 6 rotates on the fixed shaft 4, and then the disc 6 drives multiple fans 7 to rotate synchronously, further increasing the range of activity of the fan 7, increasing the air flow area, and improving the cooling efficiency. It is convenient and practical.

[0019] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of protection of the technical solution of the present invention.
