Description

Technical Field

[0001] The invention belongs to the technical field of moisture and flood prevention of transformer substations, and in particular relates to a transformer substation with moisture and flood prevention functions. Background Art

[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy, and distributes electric energy. The substation in a power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid.

[0003] In a humid environment, especially during the flood season, the temperature difference between the ambient temperature and the air temperature is relatively large. The temperature inside or on the surface of the substation is lower than the dew point temperature, which will form condensation. Similarly, the lack of air circulation inside the substation makes it impossible to remove water vapor, which makes it easy for the steam inside the substation to saturate and cause condensation inside the substation. If the electrical equipment in the substation is operated in this environment for a long time, the contact between the condensation water and the electrical equipment will destroy its insulation performance, and the metal structure of the equipment will gradually rust and destroy its use effect, so it is necessary to carry out moisture-proof treatment inside the substation.

[0004] The existing announcement number CN213660899U discloses a moisture-proof substation that is easy to inspect, including a moisture-proof mechanism and a drying mechanism; the moisture-proof mechanism: it includes a substation box, the upper surface of the substation box is provided with a waterproof mechanism, the left and right sides of the substation box are provided with vents, the inner bottom side of the substation box is fixed with a support column, the top of the support column is provided with a support plate, the left and right sides of the support plate are provided with baffles, the upper surface of the support plate is provided with a mounting plate, the rear side of the mounting plate is fixed to the inner side of the substation box On the rear side, a supporting mechanism is provided on the bottom side of the substation box; a drying mechanism: it includes four orifice box bodies, and drying bags are placed inside the four orifice box bodies: although it has a certain moisture-proof effect, the baffle installed in the box body can prevent rainwater from splashing into the box body through the vents, but the baffle will also hinder the air flow at the vents during daily use, and the humid air from the outside will easily enter the box body, and it cannot play a good moisture-proof effect. The drying bags used need to be replaced regularly, and the maintenance is very cumbersome, and it cannot cope with the problem of rising water levels during the flood season.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0045] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] See also Figures 1 to 15 As shown, the present invention provides a substation with moisture and flood prevention functions, comprising a fixed base 1, the upper part of the fixed base 1 is fixedly connected to a limited position part 2;

[0047] One side of the limiting part 2 is fixedly connected with the flood control part 3. When the flood season comes, the flood control part 3 can float on the water surface and be limited by the limiting part 2 to move in the vertical direction, so that the flood control part 3 is always above the water surface, thereby preventing water from seeping into the flood control part 3 and causing damage to the internal equipment;

[0048] The flood control part 3 includes a protective cabinet 301, a fixed frame 302, a rotating rod 303, a locking block 304, a locking bolt 305, a floating box 306 and a protective ceiling 307. Both sides of the protective cabinet 301 are fixedly connected to the corresponding bearing seat 203, the upper end of the fixed frame 302 is fixedly connected to the lower end of the protective cabinet 301, one end of the rotating rod 303 is rotatably connected to the fixed frame 302, the locking block 304 is slidably connected to the inside of the two ends of the fixed frame 302, one end of the locking bolt 305 is rotatably connected to the inside of the locking block 304, the other end of the locking bolt 305 is threadedly connected to the inside of the fixed frame 302, the two ends of the locking block 304 cooperate with the other end of the corresponding rotating rod 303, and the protective ceiling 307 is fixedly connected to the upper part of the protective cabinet 301; a sealing part 4 is provided inside the flood control part 3, and the upper part of the flood control part 3 can be closed by the sealing part 4 to isolate the inside of the flood control part 3 from the external environment;

[0049] A dehumidification part 5 is fixedly arranged inside the sealing part 4, and the dehumidification part 5 can dehumidify, heat and stir the air inside the flood control part 3, so as to control the air humidity inside the flood control part 3 and avoid condensation inside the flood control part 3;

[0050] A monitoring part 6 is provided inside the sealing part 4, and the monitoring part 6 is electrically connected to the sealing part 4 and the dehumidification part 5. The monitoring part 6 is responsible for monitoring the air humidity inside the flood control part 3, and realizes the sealing and opening of the flood control part 3 by controlling the sealing part 4, and heats and stirs the air through the dehumidification part 5 to reduce the air humidity inside the flood control part 3.

[0051] Specifically, when the flood season comes, if the monitoring unit 6 detects that the air humidity inside the flood control unit 3 is high, the monitoring unit 6 controls the moisture removal unit 5 to heat the air inside the flood control unit 3 to reduce the air humidity inside the flood control unit 3 and discharge the air with water vapor from the inside of the flood control unit 3;

[0052] Furthermore, when the flood season arrives and the water level is high, the floating box 306 is in the water and uses its own buoyancy to drive the fixing frame 302 to always float on the water surface, so that the protective cabinet 301 is away from the water surface to prevent water from flowing into the interior of the protective cabinet 301 and damaging the equipment. Then, both sides of the protective cabinet 301 are fixed by the limiting part 2 to prevent the protective cabinet 301 from moving with the water flow during the floating process;

[0053] The design of multiple floating boxes 306 is adopted. Even if some floating boxes 306 are damaged, they can still have sufficient buoyancy to drive the protective cabinet 301 to float on the water surface. When the floating box 306 needs to be replaced, it is only necessary to rotate the locking bolt 305 to drive the locking block 304 to move out of the interior of the fixing frame 302. At this time, the other end of the rotating rod 303 loses the limiting fixation of the locking block 304. The rotating rod 303 is rotated to open, and then the floating box 306 is slid out of the interior of the fixing frame 302 for replacement. Then the rotating rod 303 is rotated to close, and the floating box 306 is fixed inside the fixing frame 302. Then the locking bolt 305 is rotated into the interior of the fixing frame 302, so that the locking block 304 fixes the other end of the rotating rod 303 inside the fixing frame 302. At this point, the convenient maintenance and replacement of the floating box 306 is completed.

[0054] When the humidity of the external air is high for a long time, the monitoring unit 6 will control the sealing unit 4 to seal and isolate the flood control unit 3 from the external air to prevent the humidity inside the flood control unit 3 from further increasing, and then control the moisture removal unit 5 to heat the air inside the flood control unit 3 for internal circulation to prevent the temperature difference from causing condensation of water vapor inside the flood control unit 3, resulting in damage to the equipment;

[0055] When the monitoring unit 6 detects that the air humidity inside the flood control unit 3 is low and within a normal range, the monitoring unit 6 controls the sealing unit 4 to open, so that the interior of the flood control unit 3 can exchange air with the external environment. At the same time, the moisture removal unit 5 can also absorb the humid water vapor entering the flood control unit 3 to avoid an increase in humidity inside the flood control unit 3.

[0056] See also Figure 5 , Figure 6 and Figure 8 As shown, the overall configuration of the floating box 306 is square, so that the floating box 306 can be installed without paying attention to the direction during the installation process, thereby improving the convenience of installation and maintenance. A limiting cavity is opened at the lower end of the floating box 306, and the limiting cavity cooperates with the upper end of the floating box 306. Through the combination of the upper and lower ends of the two floating boxes 306, the stability of the floating box 306 inside the fixed frame 302 can be increased.

[0057] See also Figure 5 , Figure 6 and Figure 8As shown, a limiting groove is provided on the outer edge of the floating box 306, and a limiting ridge matching the limiting groove is provided inside the fixing frame 302. The limiting ridge inside the fixing frame 302 provides guidance and limitation for the floating box 306, and can also further improve the stability of the floating box 306 inside the fixing frame 302.

[0058] See also Figures 1 to 4 As shown, the limiting part 2 includes a limiting column 201, a rotating wheel 202, a bearing seat 203 and a bearing ring 204. A plurality of limiting columns 201 are provided, and the lower end of the limiting column 201 is fixedly connected to the inside of the fixed base 1, the outer edge of the rotating wheel 202 is in contact with the outer edge of the limiting column 201, the bearing seat 203 is provided at the upper end of the limiting column 201, and the rotating wheel 202 is rotatably provided inside the bearing seat 203, the bearing ring 204 is fixedly provided inside the lower end of the bearing seat 203, and the bearing ring 204 is matched with the middle part of the limiting column 201, and the whole of the bearing ring 204 is made of rubber material;

[0059] When the protective cabinet 301 floats on the water, the bearing seat 203 moves together with the protective cabinet 301, and at the same time, the rotating wheel 202 inside the bearing seat 203 rotates along the outer edge of the limiting column 201. The rotation of the rotating wheel 202 reduces the direct friction of the bearing seat 203 on the limiting column 201, thereby extending the service life of the limiting column 201;

[0060] When the protective cabinet 301 floats on the water, the bearing ring 204 at the lower end of the bearing seat 203 contacts the limiting column 201, so that the entire mass of the protective cabinet 301 is applied to the limiting column 201 for bearing. The elastic characteristics of the rubber itself can avoid friction between the lower end of the bearing seat 203 and the limiting column 201, thereby improving the stability of the protective cabinet 301.

[0061] See also Figures 9 to 13As shown, the sealing part 4 includes a sealing frame 401, a limiting plate 402, a sealing plate 403, an extrusion seat 404, an extrusion screw 405, a driving rod 406 and a driving motor 407. The sealing frame 401 is fixedly arranged inside the protective ceiling 307, the limiting plate 402 is fixedly arranged inside the sealing frame 401, one end of the sealing plate 403 is rotatably connected to the inside of the limiting plate 402, the other end of the sealing plate 403 is slidably connected to the inside of the limiting plate 402, one side of the sealing plate 403 cooperates with the inside of the sealing frame 401, and the extrusion seat 404 is slidably arranged Inside the sealing frame 401, the inside of the extrusion seat 404 is slidably connected to the other end of the sealing plate 403, the extrusion screw 405 rotating device is inside the sealing frame 401, and the outer edge of the extrusion screw 405 is threadedly connected to the inside of the extrusion seat 404, one end of the driving rod 406 is meshed with the bevel gears at one end of the two extrusion screws 405 through the bevel gear, the driving motor 407 is fixedly connected to the inside of the sealing frame 401, the output end of the driving motor 407 is fixedly connected to the other end of the driving rod 406, and the driving motor 407 is electrically connected to the monitoring unit 6;

[0062] The output end of the driving motor 407 drives the driving rod 406 to rotate, and the rotation of the driving rod 406 transmits power to the extrusion screw 405, driving the extrusion screw 405 to rotate. Then the rotation of the extrusion screw 405 drives the extrusion seat 404 threadedly connected thereto to move horizontally, so that the extrusion seat 404 squeezes the other end of the sealing plate 403, and the sealing plate 403 rotates with one end as the axis. The rotation of the sealing plate 403 can open and close the interior of the sealing frame 401, thereby realizing the opening and closing of the interior of the protective cabinet 301.

[0063] See also Figures 9 to 13 As shown, an arc-shaped limiting groove is provided inside the limiting plate 402, and the inside of the limiting groove is slidably connected to the other end of the sealing plate 403, and the arc of the guide groove matches the rotation path of the other end of the sealing plate 403. An extrusion groove is vertically provided inside the extrusion seat 404, and the inside of the extrusion groove is also slidably connected to the other end of the sealing plate 403, and the height of the extrusion groove is the same as that of the limiting groove.

[0064] By moving the extrusion seat 404, the extrusion groove inside it can squeeze the other end of the sealing plate 403, so that the other end of the sealing plate 403 can also move in an arc shape along the arc-shaped limiting groove inside the limiting plate 402 during the process of moving vertically along the inside of the extrusion groove. Through the mutual cooperation of the extrusion groove and the limiting groove, the sealing plate 403 can rotate with one end as the axis, thereby realizing the opening and closing of the sealing plate 403 inside the sealing frame 401.

[0065] See also Figures 9 to 13As shown, two extrusion screws 405 are grouped together and meshed with one end of the corresponding driving rod 406 through a bevel gear, and the threads of the two extrusion screws 405 in a group are the same. The rotation directions of the two bevel gears meshed with one end of the driving rod 406 are opposite, so that the rotation directions of the corresponding extrusion screws 405 are also opposite, so that the extrusion seats 404 corresponding to the extrusion screws 405 can move toward and away from each other along the extrusion screws 405, thereby realizing the simultaneous opening and closing of the two sealing plates 403.

[0066] See also Figure 2 , Fig.14 and Fig.15 As shown, the dehumidification unit 5 includes an installation box 501, an exhaust fan 502, a dehumidification bag 503 and an electric heater 504. The installation box 501 is fixedly connected to the inside of the sealing frame 401, the exhaust fan 502 is fixedly arranged at the upper end of the installation box 501, the dehumidification bag 503 is arranged at the upper end of the installation box 501, the outside of the dehumidification bag 503 is made of breathable and high-temperature resistant silicone cloth, and the inside is filled with silicone balls. The electric heater 504 is arranged at the lower end of the installation box 501, and the exhaust fan 502 and the electric heater 504 are electrically connected to the monitoring unit 6;

[0067] The exhaust fan 502 stirs the air flow inside the protective cabinet 301 to promote the flow of gas inside the protective cabinet 301, whether it is external circulation or internal circulation, and reduces the humidity of the air inside the protective cabinet 301;

[0068] The silica gel balls filled in the dehumidification bag 503 are used to absorb the moisture inside the protective cabinet 301 to reduce the air humidity. At the same time, the silica gel balls can be reused after evaporating the moisture at high temperature. The dehumidification bag 503 can be dried at high temperature by the electric heater 504 for repeated use, so that the dehumidification bag 503 can perform regular dehumidification for a long time.

[0069] See also Figure 2 , Fig.14 and Fig.15 As shown, the installation box 501 as a whole adopts a multi-layer hollow design, which can increase the air flow inside the installation box 501, thereby increasing the dehumidification efficiency of the dehumidification bag 503, and also increase the heat dissipation efficiency of the electric heater 504.

[0070] See also Fig.13 As shown, the monitoring unit 6 is connected to the mains electricity. The monitoring unit 6 includes an air humidity monitoring module and a microprocessor. The air humidity inside the protective cabinet 301 is monitored by the air humidity monitoring module, and the data is transmitted to the microprocessor for processing. The microprocessor controls the mutual coordination among the driving motor 407, the exhaust fan 502 and the electric heater 504. Different combinations can be used to achieve a variety of dehumidification methods and the flexibility of dehumidification.

[0071] The working principle of the present invention is as follows: when the flood season comes, when the monitoring unit 6 detects that the air humidity inside the flood control unit 3 is relatively high, the monitoring unit 6 controls the moisture removal unit 5 to heat the air inside the flood control unit 3 to reduce the air humidity inside the flood control unit 3 and discharge the air with water vapor from the inside of the flood control unit 3;

[0072] Furthermore, when the flood season arrives and the water level is high, the floating box 306 is in the water and uses its own buoyancy to drive the fixing frame 302 to always float on the water surface, so that the protective cabinet 301 is away from the water surface to prevent water from flowing into the interior of the protective cabinet 301 and damaging the equipment. Then, both sides of the protective cabinet 301 are fixed by the limiting part 2 to prevent the protective cabinet 301 from moving with the water flow during the floating process;

[0073] The design of multiple floating boxes 306 is adopted. Even if some floating boxes 306 are damaged, they can still have sufficient buoyancy to drive the protective cabinet 301 to float on the water surface. When the floating box 306 needs to be replaced, it is only necessary to rotate the locking bolt 305 to drive the locking block 304 to move out of the interior of the fixing frame 302. At this time, the other end of the rotating rod 303 loses the limiting fixation of the locking block 304. The rotating rod 303 is rotated to open, and then the floating box 306 is slid out of the interior of the fixing frame 302 for replacement. Then the rotating rod 303 is rotated to close, and the floating box 306 is fixed inside the fixing frame 302. Then the locking bolt 305 is rotated into the interior of the fixing frame 302, so that the locking block 304 fixes the other end of the rotating rod 303 inside the fixing frame 302. At this point, the convenient maintenance and replacement of the floating box 306 is completed.

[0074] When the humidity of the external air is high or lasts for a long time, the monitoring unit 6 will control the sealing unit 4 to seal and isolate the flood control unit 3 from the external air to prevent the humidity inside the flood control unit 3 from further increasing, and then control the moisture removal unit 5 to heat the air inside the flood control unit 3 for internal circulation to prevent the temperature difference from causing water vapor condensation inside the flood control unit 3, resulting in equipment damage;

[0075] When the monitoring unit 6 detects that the air humidity inside the flood control unit 3 is low and within a normal range, the monitoring unit 6 controls the sealing unit 4 to open, so that the interior of the flood control unit 3 can exchange air with the external environment. At the same time, the moisture removal unit 5 can also absorb the humid water vapor entering the flood control unit 3 to avoid an increase in humidity inside the flood control unit 3.

[0076] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
