Description

Technical Field

[0001] The utility model belongs to the technical field of electric power facilities, and in particular relates to a prefabricated transformer substation capable of improving air flow in a box. Background Art

[0002] Substations are mainly used to transform voltage and current, receive electric energy and distribute electric energy in power systems. Currently, most of them are produced and installed in prefabricated forms, that is, factory-prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme, which organically combines the functions of transformer step-down and low-voltage distribution, thus distinguishing them from traditional distribution rooms and distribution stations, making them more convenient to use and install.

[0003] Since power facilities are centrally installed in substations, in order to ensure stable and safe operation, corresponding cooling measures are currently set up for substations. The most common method is to install fans to exhaust the hot air in the substation and send cold air from the outside into the substation to cool the power facilities. However, during the use of general substations, it is easy for dust and impurities from the outside to be sent into the substation at the same time, causing the facilities to be affected. Simply setting up filter plates to prevent dust will cause air vents to be blocked as the use time increases, requiring regular maintenance and cleaning, which will lead to inconvenience in the use of the substation and reduced actual air circulation performance.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-5 As shown, a prefabricated substation capable of improving air flow in the box comprises a substation box 1 and a controller, and ventilation mechanisms are arranged on both the left and right sides of the substation box 1;

[0027] The ventilation mechanism includes a fan 11, a cleaning component and an air guide component. The fan 11 is embedded in the side of the substation box 1, the cleaning component and the air guide component are respectively arranged on both sides of the fan 11, and the cleaning component is arranged outside the substation box 1;

[0028] The cleaning assembly includes a filter plate 12, a brush 2, a retractor and a driver. The filter plate 12 is embedded in the side of the substation box 1, the retractor is arranged in the middle of the filter plate 12, the brush 2 is connected to the output shaft of the retractor and has a bristle end facing the filter plate 12, and the driver is arranged on the filter plate 12 and is transmission-connected to the retractor;

[0029] The wind guide assembly includes a wind guide plate 3 and a toggle, the wind guide plate 3 is connected to the inner wall of the transformer substation box 1, and the toggle is arranged in the transformer substation box 1 and connected and matched with the wind guide plate 3.

[0030] When the substation is in operation, the ventilation mechanism will ventilate and cool the substation box 1, wherein the fans 11 in the two ventilation mechanisms operate in opposite directions, i.e. one side draws external cold air into the substation box 1, and the other side discharges the hot air in the substation box 1, thereby forming air circulation and cooling to ensure the stable and safe operation of the facilities in the substation box 1, wherein the filter plate 12 will prevent dust and debris in the external environment from entering the substation box 1, but with the increase of operating time and the influence of the surrounding environment, dust and debris will cover the filter plate 12, at this time, in order to avoid the decrease in the smoothness of air circulation caused by the clogging of dust and debris, the controller will regularly turn on the cleaning component to clean the filter plate 12, wherein the controller adopts any one with a timing function and The single chip microcomputer with control function is a prior art in this field to periodically start the operation of the components, so it will not be elaborated here. When the cleaning component is started, the telescopic device contracts to pull the brush 2 close to the filter plate 12 and keep it in contact. The driver drives the telescopic device so that the brush 2 rotates around the center of the filter plate 12, thereby generating a scrubbing and cleaning action, so that the dust and impurities attached to the surface of the filter plate 12 are swept away. Furthermore, due to the flow direction of the air, the cleaning components of the ventilation mechanisms on both sides are only started in the exhaust state, that is, to prevent the swept dust and impurities from being attached to the surface of the filter plate 12 again or entering the substation box 1 with the flow of air. The fans 11 in the ventilation mechanisms on both sides are regularly exhausted and replaced, thereby ensuring the air circulation and cleaning effectiveness in the substation box 1.

[0031] Furthermore, during use, the toggle switch in the air guide assembly will also synchronously toggle the air guide plate 3 in the substation box 1, causing the air guide plate 3 to cyclically flip up and down to adjust the input direction of the cold air drawn into the substation box 1, thereby more effectively cooling the facilities at different heights in the box, and more effectively discharging the rising hot air from the substation box 1.

[0032] The telescopic device includes a sleeve 4, a slide 41, an electromagnet 42, a tension spring 43 and a rotating rod 44. The sleeve 4 is fixedly connected to the center of the filter plate 12 and the inner cavity of the sleeve 4 is a step cavity structure. The slide 41 is slidably arranged in the sleeve 4 through a guide rib. The electromagnet 42 is arranged at the bottom of the sleeve 4. The rotating rod 44 is coaxially rotatably connected with the slide 41 and slides out of the sleeve 4 to be fixedly connected with the brush 2. The tension spring 43 is sleeved on the rotating rod 44 and connects the slide 41 and the inner wall of the opening side of the sleeve 4. The slide 41 is made of metal that can be adsorbed by a magnet.

[0033] The driver includes a micro motor 5, a driving wheel 51 and a matching ring. The micro motor 5 is embedded in the sleeve 4 adjacent to the lower side of the filter plate 12. The driving wheel 51 is rotatably arranged on the outer side of the filter plate 12 and is transmission-connected to the output shaft of the micro motor 5. The matching ring is concentrically fixedly sleeved with the rotating rod 44 and is transmission-connected to the driving wheel 51.

[0034] In the initial state, the tension spring 43 remains contracted so that the rotating rod 44 extends out of the sleeve 4, that is, the cleaning brush is pushed away from the filter plate 12 to avoid blocking and hindering the extraction of air. When the cleaning component starts cleaning, the electromagnet 42 starts the adsorption slide 41. At this time, the slide 41 moves toward the electromagnet 42 side to drive the rotating rod 44 to contract and make the cleaning brush fit the filter plate 12. Finally, the micro motor 5 is started and transmitted through the connection between the driving wheel 51 and the matching ring, so that the cleaning brush sweeps around the filter plate 12 for cleaning. After cleaning, the electromagnet 42 is powered off, and the tension spring 43 is reset to pull the slide 41, that is, the cleaning brush is moved away from the filter plate 12.

[0035] The driving wheel 51 and the matching ring are both gears and mesh with each other.

[0036] The driving wheel 51 and the matching ring are both friction wheels and abut against each other.

[0037] There are several wind deflectors 3 which are equidistantly hinged on the inner wall of the transformer substation box 1. The actuator includes an electrically controlled telescopic rod 6, a vertical rod 61 and a horizontal rod 62. The electrically controlled telescopic rod 6 is fixed in the transformer substation box 1 and is located on the upper side of the wind deflector 3. The vertical rod 61 is connected to the output shaft of the electrically controlled telescopic rod 6. The number of horizontal rods 62 matches the number of wind deflectors 3. A sliding groove 63 matching the horizontal rod 62 is opened on the side of the wind deflector 3. The horizontal rod 62 extends into the sliding groove 63 of the wind deflector 3 and is slidably connected to the wind deflector 3.

[0038] During the process of extracting and exhausting air, the output shaft of the electrically-controlled telescopic rod 6 cyclically extends and retracts, thereby cyclically pulling the vertical rod 61 up and down. At this time, the vertical rod 61 will move the slide groove 63 of the air guide plate 3 through a plurality of cross rods 62, that is, the vertical rod 61 pushes and pulls the air guide plate 3 so that the direction of the air guide plate 3 is flipped up and down, thereby changing the input direction of the cold air drawn into the substation box 1, so as to achieve a better cooling and air circulation effect.

[0039] A rain cover 7 corresponding to the filter plate 12 is also provided on the outside of the substation box 1, and the rain cover 7 is a shutter structure; this can prevent rainwater from falling on the filter plate 12 when it rains, causing dust impurities and water condensation to cause inconvenience in later cleaning, and can also prevent external water from entering the substation box 1 and causing safety hazards.

[0040] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
