Description

Technical Field

[0001] This utility model belongs to the field of substation monitoring technology, specifically relating to a comprehensive monitoring device for power plants and substations. Background Technology

[0002] A power plant, also known as a power station, is a factory that converts various primary energy sources found in nature into electrical energy. A substation is a place in the power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. Generally, power plants have substations built inside them. The substations inside power plants are usually step-up substations, whose function is to step up the electrical energy generated by the generator and feed it into the high-voltage power grid. Substations generally achieve the purpose of resource utilization when they are in operation. At this time, photovoltaic structures are installed on top of them to supply power to the electrical equipment inside. However, when the photovoltaic structures are exposed to rain, water film will form on their surface, affecting the subsequent absorption of sunlight by the photovoltaic structures. Although some existing substations have solved this problem, they often still have certain shortcomings in actual use, so they need to be improved.

[0003] Chinese patent CN 221669357 U discloses a substation integrated automation monitoring device, including a housing. Two sliding frames are fixedly connected to the top of the housing. Each sliding frame has a threaded rod rotatably connected inside. One end of each threaded rod passes through the sliding frame and extends to the outside. A transmission assembly is provided between the two threaded rods. Threaded blocks are threadedly connected to the outer surface of each threaded rod. A fixing frame is fixedly connected to the top of each threaded block. A rotating rod is rotatably connected between opposite sides of the two fixing frames. In rainy weather, this invention allows the motor to be started via the control panel, causing the rain cover on the winding drum to unfold and protect the solar panels. Simultaneously, during the unfolding of the rain cover, a scraper removes water stains, dust, weeds, and other debris from the surface of the solar panels, preventing any impact on the subsequent power generation efficiency of the solar panels.

[0004] However, while the above-mentioned technical solution can achieve the purpose of shading and waterproofing the surface of the photovoltaic panel, the motor and winding film on it are completely exposed. Rainy weather will affect the motor, and in hot weather, the motor and rainproof film will be exposed to the sun, which will cause damage and increase the cost of subsequent replacement. The rack and gears exposed to the outside will develop rust spots after being corroded by rainwater, affecting the subsequent transmission effect. In severe cases, it will cause the rainproof film to wrinkle, thus affecting subsequent use. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a comprehensive monitoring device for power plants and substations to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A comprehensive monitoring device for power plants and substations includes: a substation, a support base fixedly connected to the top of the substation, an air inlet pipe fixedly connected to one side of the substation, a cavity inside the support base, two collection chambers inside the support base, a servo motor fixedly connected to one side of the inner wall of each collection chamber, a take-up roller fixedly connected to the output end of the servo motor, a protective film wound around the surface of the take-up roller, guide grooves on both sides of the inner wall of the cavity, an electric slide rail installed inside the guide groove, an electric slider slidably connected inside the electric slide rail, and a fixed connection inside the electric slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The substation can supply power to its internal electrical equipment through photovoltaic panels. At the same time, the photovoltaic panels can be retracted into the cavity and protected by a protective film during rainy weather to prevent rainwater from accumulating on the surface and causing water film to form on the surface, which would affect the subsequent absorption of sunlight. When the photovoltaic panels enter the cavity, the dust, impurities and rainwater on the surface can be scraped off by the push bar and accumulated in the collection tank. Then, they are discharged through the guide pipe, which avoids the accumulation of water and impurities in the collection tank. When the protective film protects the photovoltaic panel, it is stretched by the electric slide rail to cover the photovoltaic panel. When not in use, it can be rolled up by the winding roller to avoid wrinkles in the protective film. The overall protective structure is located inside the support base to avoid the damage caused by sun exposure and rainwater erosion, which plays a certain protective role and can extend its service life to a certain extent.

[0016] (2) When the internal temperature of the substation is too high, it can be detected in time. The air is drawn by the fan blades to cool the inside of the substation. The vibration sensor can detect the vibration signal to prevent some equipment parts from loosening. At the same time, the ultra-high frequency sensor can detect the partial discharge activity of electrical equipment to prevent insulation failure and achieve the purpose of comprehensive detection. When the external gas enters the substation, it can filter the impurities contained in the gas to prevent dust from entering the inside of the substation and affecting its internal parts.

[0031] Example 2:

[0032] Please see Figure 1 , Figure 5 and Figure 6As shown, a protective shell is fixedly connected to one side of the inner wall of the intake pipe 3.

The output end of the electric telescopic rod 14 lowers the photovoltaic panel 18, while the output end of the servo motor 4 rotates the winding roller 5 to release the protective film 6. Simultaneously, the electric slider 9 moves the push bar 11 to the left. The scraper 16 at the bottom of one side of the push bar 11 scrapes away rainwater impurities from the photovoltaic panel 18, causing them to fall onto the guide block 12 and eventually enter the collection tank 13. Rainwater also enters the collection tank 13 through the guide block 12 and is finally discharged through the guide pipe 30. When the temperature inside the substation 1 is too high, the temperature sensor 25 detects it and transmits a signal to the control panel 29. The control panel 29 controls the drive motor 19 and the electric push rod 23 to work. The output of the drive motor 19 drives the fan blade 20 to rotate. Then the fan blade 20 generates suction, which causes the air intake pipe 3 to draw gas from the outside. The gas continuously enters the air intake pipe 3 and then enters the interior of the substation 1 through the air intake pipe 3 to cool it down. The electric push rod 23 drives the connecting plate to move to the right, thereby causing the blocking strip 24 to separate from the through slot, so that the exhaust hole 22 is opened. At this time, the hot gas inside the substation 1 can be discharged.
