Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment, and in particular to an intelligent box-type substation and a use method thereof. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation, is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme and includes high-voltage switchgear, distribution transformers and low-voltage distribution devices. Box-type substation replaces the original civil power distribution room and distribution station and becomes a new type of complete set of power distribution equipment.

[0003] A Chinese patent application with publication number CN109256700A discloses a box-type substation heat dissipation system, including a box body, the inner cavity of the box body includes a high-voltage chamber, a transformer chamber and a low-voltage chamber, the transformer chamber is used to install the transformer, and the box body is provided with a plurality of dispersed box doors, and the box doors are embedded with ventilation windows, which are shutters.

[0004] When the box-type substation cooling system is in operation, the transformer is the largest source of heat, and the heat in the transformer room can be dissipated outward through the shutters. The heat in the high-voltage and low-voltage rooms can also be dissipated through the shutters on the box doors.

[0005] However, in actual implementation, the above box-type substation heat dissipation system still has some shortcomings: in the rainy season, the shutters cannot automatically close together, so that large gaps will be formed between the shutters. Although these gaps achieve the effect of heat dissipation, they also facilitate a large amount of rainwater to enter the box, exacerbating the moisture condition of the internal parts of the box. Summary of the invention

[0006] The present invention provides an intelligent box-type substation and a method for using the same, aiming to solve the problem in the related art that when the rainfall is heavy, more rainwater may enter the box body, thereby aggravating the moisture of the internal components of the box body.

[0008] When it rains, the flow sensor can detect the flow of rainwater and control the operation of the drive motor accordingly. The drive motor controls the sliding block to slide downward through the threaded rod. The top rod moves downward with the sliding block, and the blades are pressed against the top rod under the action of gravity and deflect downward. At this time, the gap between two adjacent blades will gradually narrow, which can reduce the passage of rainwater in the gap, thereby reducing the rainwater entering the chassis and alleviating the moisture of the components inside the chassis.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] Combine the following Figures 1 to 7 The intelligent box-type substation of the present invention is described.

[0040] like Figures 1 to 5 As shown, the intelligent box-type substation of the present invention includes a chassis 1 and a heat dissipation unit 2.

[0041] The chassis 1 has a high-voltage power distribution cabinet 11 in it. The peripheral wall of the chassis 1 is provided with a door 12 for entering and exiting the chassis 1 . The staff can enter the chassis 1 through the door 12 to perform regular maintenance on the high-voltage power distribution cabinet 11 .

[0042] There are multiple heat dissipation units 2 which are dispersedly arranged on the chassis 1. The following description will be made by taking one of the heat dissipation units 2 as an example.

[0043] The heat dissipation unit 2 includes a heat dissipation window 21 , a window frame 22 , a blade 23 , a driving component and a flow sensor 24 .

[0044] The heat dissipation window 21 is opened on the side wall of the chassis 1 , and the window frame 22 is fixedly installed at the heat dissipation window 21 .

[0045] The window frame 22 includes an outer frame 221 and an inner frame 222 .

[0046] The outer frame 221 is fixedly connected to the chassis 1, and the inner frame 222 is slidably embedded in the outer frame 221 along the front-back direction. In the initial state, the inner frame 222 is closer to the inner side of the chassis 1 than the outer frame 221. A distance adjusting member 223 is connected between the inner frame 222 and the outer frame 221. The number of the distance adjusting members 223 can be one, two or other numbers, which are not limited here. The distance adjusting member 223 can sense the external temperature and adjust the distance between the inner frame 222 and the outer frame 221.

[0047] In one embodiment, the distance adjusting member 223 is a temperature-controlled telescopic rod. When the outside temperature rises, the temperature-controlled telescopic rod is extended to move the inner frame 222 away from the outer frame 221 .

[0048] In another embodiment, in another embodiment, the distance adjusting member 223 includes an electric telescopic rod and a temperature sensor, the electric telescopic rod is connected between the inner frame 222 and the outer frame 221, the temperature sensor is installed on the outer frame 221, and the temperature sensor is electrically connected to the electric telescopic rod through a processor, and the processor can be set on the outer frame 221.

[0049] There are multiple blades 23 and they are arranged at equal intervals in the vertical direction. The blades 23 are rotatably installed in the outer frame 221 and their rotation axes extend in the left-right direction. A top rod 25 is mounted on the lower half of the blade 23. The top rod 25 extends in the left-right direction and can slide vertically relative to the outer frame 221.

[0050] The driving assembly is disposed on the window frame 22 and connected to the plurality of push rods 25 so as to drive the plurality of push rods 25 to slide synchronously.

[0051] Specifically, the driving assembly includes a threaded rod 26 and a sliding block 27 .

[0052] The threaded rod 26 extends vertically and is rotatably disposed on the outer frame 221 . The outer frame 221 is provided with a driving motor 221 a for driving the threaded rod 26 to rotate. The driving motor 221 a is electrically connected to the distance adjusting member 223 .

[0053] The number of sliding blocks 27 and push rods 25 is equal and corresponds one to one. The sliding blocks 27 are fixedly connected to the corresponding push rods 25. The outer frame 221 is provided with a guide groove 221b for guiding the vertical sliding of the sliding blocks 27. The sliding blocks 27 are slidably fitted in the guide groove 221b, and the sliding blocks 27 are threadedly connected to the threaded rod 26.

[0054] It should be noted that the threaded rod 26 and the sliding block 27 together constitute a transmission unit. In this embodiment, the transmission unit is not limited to one, but may be two. The two transmission units may be disposed on the left and right sides of the top rod 25 .

[0055] The top of the chassis 1 forms a slope 13 and a protrusion 14. The protrusion 14 is arranged at the bottom of the slope 13 and has a rain gutter 141 for receiving rainwater inside. The rain gutter 141 extends in the left and right directions. The left end of the rain gutter 141 forms an inlet 141a facing the slope 13. The inlet 141a is connected to the bottom of the slope 13. The right end of the rain gutter 141 forms an outlet 141b. The bottom surface of the rain gutter 141 also has a slope. The flow sensor 24 is installed in the rain gutter 141 and is electrically connected to the drive motor 221a through the controller. The controller is installed on the outer frame 221. The flow sensor 24 is used to measure the flow of rainwater and send the measured data to the controller. The controller analyzes the measured data and controls the operation of the drive motor 221a according to the calculation results. It should be noted that the controller can be connected to a remote data terminal. The operator can remotely detect the operation of the drive motor 221a through the remote data terminal, and can also remotely operate the operation of the drive motor 221a through the remote data terminal.

[0056] Continue to refer Figures 4 to 7 The inner frame 222 is provided with a plurality of filter plates 29 evenly distributed in the left-right direction. The filter plates 29 are rotatably connected to the inner frame 222 via a support shaft 291. Specifically, the support shaft 291 extends vertically, and the bottom end is fixedly connected to the filter plate 29, and the top end is rotatably connected to the inner frame 222. It can be understood that the rotation axis of the filter plate 29 extends vertically. An elastic member is connected between the support shaft 291 and the inner frame 222. In this embodiment, the elastic member can directly adopt a coil spring 292 sleeved on the support shaft 291. Under the action of the coil spring 292, the left edge of the filter plate 29 is pressed against the upper edge of the blade 23.

[0057] A scraper 293 is attached to the surface of the filter plate 29 facing away from the chassis 1, and a flexible block is formed on the side of the scraper 29 facing the filter plate 29, and the flexible block is in extrusion contact with the surface of the filter plate 29. In this embodiment, the flexible block can directly adopt a rubber block or a sponge block. A slide 294 is provided on the filter plate 29. When the filter plate 29 is in a straight state, the length direction of the slide 294 is consistent with the left and right direction. A slider is provided on the scraper 293, and the slider is slidably matched in the slide 294. In this embodiment, the number of the slider and the slide 294 can be one or two, etc., and there is no limitation on this.

[0058] A guide rod 293a is rotatably mounted on the scraper 293, and an arc-shaped slideway 222a is provided on the inner wall of the inner frame 222. Both ends of the arc-shaped slideway 222a are closed, and the guide rod 293a is slidably fitted in the arc-shaped slideway 222a. The scraper 293 is provided with a receiving groove 293b facing the filter plate 29, and the receiving groove 293b extends in the vertical direction. The inner frame 222 is provided with a sewage guide port 222b adjacent to the end of the arc-shaped slideway 222a, and the sewage guide port 222b is downwardly connected to the external space.

[0059] refer to Figures 1 to 7 The working principle of the intelligent box-type substation of the present invention is as follows:

[0060] In the initial state, the top rod 25 is in an upper position, so that the blade 23 deflects more greatly, and the gap between adjacent blades 23 is larger, so that the components in the chassis 1, such as the high-voltage distribution cabinet 11, dissipate heat outward through this gap, and the gap can be set as a heat dissipation gap. At this time, the filter plate 29 is straight under the restriction of the blade 23, and two adjacent filter plates 29 are in contact. Multiple filter plates 29 together form a larger filtering area, which is convenient for filtering dust and other impurities carried in the air when the outside air enters the chassis 1. The setting of the filter plate 29 reduces the situation of dust entering the chassis 1, and realizes the protection of the components in the chassis 1.

[0061] When it rains, rainwater enters the rain gutter 141 from the slope 13, and flows along the rain gutter 141 to the flow sensor 24. The flow sensor 24 detects the flow of rainwater and controls the operation of the drive motor 221a accordingly. The drive motor 221a controls the threaded rod 26 to rotate, and under the restriction of the guide groove 221b, the sliding block 27 slides downward. The top rod 25 moves downward with the sliding block 27, and the blade 23 is pressed against the top rod 25 under the action of gravity and deflects downward. At this time, the gap between two adjacent blades 23 will gradually narrow, that is, the heat dissipation gap will gradually narrow, which can reduce the passage of rainwater in the heat dissipation gap, thereby reducing the rainwater entering the chassis 1 and alleviating the moisture of the components inside the chassis 1.

[0062] When it rains, dust in the air can be carried by rainwater to the ground. At this time, the downward deflection of the blade 23 can cause its upper edge to move toward the outside of the chassis 1. Under the action of the coil spring 292, the left edge of the filter plate 29 is pressed against the upper edge of the blade 23, and the filter plate 29 is also deflected, with its right edge lifted. At this time, there is a gap between two adjacent filter plates 29, which can just make up for the reduction of the heat dissipation gap. In other words, when the heat dissipation gap gradually decreases, the gap between two adjacent filter plates 29 gradually expands, ensuring the stability of the entire heat dissipation channel from the inside of the chassis 1 to the outside, and ensuring the normal dissipation of heat in the chassis 1.

[0063] When the filter plate 29 deflects, it tends to drive the slider and the scraper 293 to deflect synchronously. Under the restriction of the guide rod 293a and the arc-shaped slideway 222a, the guide rod 293a moves along the arc-shaped slideway 222a under the power of the filter plate 29. When moving, the guide rod 293a contacts the side wall of the arc-shaped slideway 222a and generates friction. Under the action of the friction, the guide rod 293a can rotate, so that the guide rod 293a moves more smoothly in the arc-shaped slideway 222a.

[0064] At the same time, the guide rod 293a will slide with the scraper 293 and the flexible block. When the flexible block slides on the plate surface of the filter plate 29 away from the chassis 1, it will scrape off the dust and other impurities on the plate surface, and the scraped impurities will accumulate in the receiving groove 293b. When the guide rod 293a slides to the end of the arc-shaped slideway 222a, the receiving groove is just above the sewage guide port 222b. At this time, the guide rod 293a will have a proper collision with the wall surface of the arc-shaped slideway 222a. Under the action of vibration force and gravity, the impurities in the receiving groove 293b will be discharged downward through the sewage guide port 222b.

[0065] In seasons with higher temperatures, such as summer, the distance adjusting member 223 increases the distance between the inner frame 222 and the outer frame 221, and the inner frame 222 moves outward a distance relative to the outer frame 221. As the distance between the inner frame 222 and the outer frame 221 increases, the distance between the blade 23 and the filter plate 29 also increases, and the two are no longer in contact. The distance adjusting member 223 controls the driving motor 221a to operate according to the sensed temperature, and the driving motor 221a drives the threaded rod 26 to reverse, and the threaded rod 26 drives the sliding block 27 and the top rod 25 to move upward, and the top rod 25 pushes the blade 23 to deflect upward, and the upper edge of the blade 23 moves toward the inner side of the chassis 1. When the upper edge of the blade 23 is against the filter plate 29 again, the upper edge of the blade 23 will gradually flatten the filter plate 29.

[0066] When the blades 23 are deflected upward, the gap between two adjacent blades 23 will continue to expand, that is, the heat dissipation gap is further increased, thereby improving the heat dissipation efficiency.

[0067] In seasons with lower temperatures, such as winter, the distance adjusting member 223 reduces the distance between the inner frame 222 and the outer frame 221 , so that the inner frame 222 can be completely embedded in the outer frame 221 .

[0068] refer to Figures 1 to 7 The present invention also provides a method for using an intelligent box-type substation, using the above-mentioned intelligent box-type substation, comprising the following steps:

[0069] When it rains, rainwater enters the rain gutter 141, and the flow sensor 24 detects the flow of rainwater and controls the operation of the driving component accordingly.

[0070] The driving assembly drives the plurality of push rods 25 to move downward synchronously, and the blades 23 are pressed tightly against the push rods 25 under the action of gravity and deflected.

[0071] The gap between adjacent blades 23 is reduced.
