Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical equipment, and more specifically to a power cabinet. Background Art
[0002] A power cabinet is a commonly used power infrastructure, and a large number of electrical components are installed inside it. When the electrical components are working, a large amount of heat will be generated. Most of the existing technologies use the method of opening multiple heat dissipation holes on the power cabinet to ensure that the heat can be dissipated normally, thereby ensuring the working environment of the electrical components;
[0003] However, the method of dissipating heat by opening multiple heat dissipation holes will affect the airtightness of the power cabinet to a certain extent. When the power cabinet needs to be installed outdoors, due to the complex and changeable outdoor environment and the relatively fragile electrical components, when it rains, if rainwater enters the power cabinet through the heat dissipation holes, it is easy to damage the electrical components inside the power cabinet and even cause short circuits or leakage of the circuit. Therefore, it is necessary to avoid rainwater seeping into the power cabinet. Most of the existing technologies use the method of setting multiple arc-shaped covers outside multiple heat dissipation holes to block the heat dissipation holes. However, when the rain is heavy, the simple arc-shaped covers cannot fully block the rainwater. At this time, to ensure the safe operation of the electrical components, it is necessary for workers to arrive at the scene to strengthen the shielding to avoid rainwater seepage. This process takes a long time and requires manual participation, which is time-consuming, laborious and inefficient. Therefore, a power cabinet that can automatically strengthen the shielding of the heat dissipation holes when there is heavy rain is needed. Summary of the Invention

[0007] It further includes a plurality of heat dissipation holes provided on the cabinet body, a plurality of shielding plates are connected inside the cabinet body, and a plurality of shielding plates can all move left and right along the cabinet body.

[0021] In addition, as an example, as Figure 3-9 shown, this example solves the problem of enabling the power cabinet to sense rainy weather.
[0022] The device includes a cabinet body 101, a rectangular frame 201 is connected inside the cabinet body 101, an induction box 501 is slidably connected to the cabinet body 101, a plurality of through holes 502 are formed in the induction box 501, a spring I 505 is fixedly connected between the induction box 501 and the cabinet body 101, a slider 401 is slidably connected to the rectangular frame 201, a sliding plate 404 is slidably connected to the slider 401, two tension springs 403 are fixedly connected between the sliding plate 404 and the slider 401, and a pressure sensor is fixedly connected to the slider 401 through a bolt.
[0023] When there is rainy weather outdoors, the rain will pour on the cabinet body 101. When the rain continues to pour and the rain intensity is large, the rain will gradually enter the induction box 501 through multiple through holes 502 on the induction box 501, thereby increasing the weight of the induction box 501 gradually. As a result, the induction box 501 gradually slides downward against the elastic force of the spring I 505. Further, the lower end of the induction box 501 gradually presses the sliding plate 404, causing the sliding plate 404 to slide downward on the slider 401 against the pulling force of the two tension springs 403, so that the sliding plate 404 presses on the pressure sensor, and then the pressure sensor is stressed, thus timely sensing the rainy weather outdoors. Furthermore, it is convenient for the subsequent operation of shielding and protecting the interior of the cabinet body 101, enabling the cabinet body 101 to automatically sense the rainy weather without manual participation;
[0024] The staff can open a through groove on one side of the induction box 501, and then regularly clean the interior of the induction box 501 through this through groove to prevent a large amount of impurities from accumulating inside the induction box 501 and affecting the induction operation of the induction box 501;
[0025] At the same time, the setting of multiple through holes 502 on the induction box 501 enables rainwater to enter the interior of the induction box 501 while preventing too many external impurities from entering the induction box 501, thus ensuring the normal operation of the induction box 501.
[0026] In addition, as an example, such as Figure 1 、 Figure 2 、 Figure 7 、 Figure 9 shown, this example solves the problem of facilitating the shielding and protection of multiple heat dissipation holes 102 in rainy weather.
[0027] This device also includes multiple heat dissipation holes 102 provided on the cabinet body 101. A plurality of shielding plates 301 are connected inside the cabinet body 101, and all the plurality of shielding plates 301 can move left and right along the cabinet body 101.
[0028] To ensure the overall heat dissipation effect inside the cabinet body 101, multiple heat dissipation holes 102 need to be opened on the cabinet body 101 to ensure that the heat generated by the electrical components inside the cabinet body 101 can be dissipated in time. When it is sensed that there is rainy weather outdoors by pressing the sliding plate 404 on the pressure sensor, the plurality of shielding plates 301 can be operated to move left and right along the cabinet body 101, thereby temporarily shielding the multiple heat dissipation holes 102 on both sides of the cabinet body 101, and further preventing rainwater from accidentally entering the cabinet body 101 through the multiple heat dissipation holes 102 and damaging the circuit inside the cabinet body 101.
[0029] In addition, as an example, such as Figure 1-2 shown, this example solves the problem of facilitating the driving of the plurality of shielding plates 301 to move.
[0030] The device also includes two connecting rods 302 slidably connected to the cabinet 101 , each connecting rod 302 is fixedly connected to a plurality of shielding plates 301 , and the cabinet 101 is fixedly connected to two electric push rods I capable of pushing the connecting rods 302 to move.
[0031] When rain is detected, the pressure sensor transmits a signal to the host computer, which transmits the signal to the electric push rods I, operating the telescopic rods of the two electric push rods I to extend, thereby causing the two connecting rods 302 to slide. The sliding of the two connecting rods 302 causes the multiple shielding plates 301 on the two connecting rods 302 to respectively shield the multiple heat dissipation holes 102, thereby shielding and protecting the inside of the cabinet 101. When the rain lasts too long, the two connecting rods 302 can be automatically operated to slide back and forth several times, thereby causing the multiple shielding plates 301 to intermittently open the multiple heat dissipation holes 102, thereby ensuring the shielding effect and facilitating the regular leakage of the multiple heat dissipation holes 102 for a certain degree of heat dissipation.
[0032] In addition, as an example, Figure 8 As shown, this example solves the problem of facilitating the collection of rainwater leaking from the sliding gap between the cabinet 101 and the sensor box 501.
[0033] The device also includes a receiving box 506 fixedly connected to the induction box 501 .
[0034] Since the cabinet body 101 and the sensing box 501 are slidably connected, a receiving box 506 is provided to prevent rainwater from seeping into the sliding connection gap. The receiving box 506 can receive rainwater leaking from the sliding gap between the cabinet body 101 and the sensing box 501, thereby preventing rainwater from falling into the cabinet body 101 and causing damage to the electrical equipment inside the cabinet body 101.
[0035] In addition, as an example, Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, this example solves the problem of improving the accuracy of rain identification.
[0036] The device also includes an outlet slot 504 arranged on the induction box 501 , and a supplementary rubber block 504 is bonded and connected in the outlet slot 504 .
[0037] Since a general power cabinet is provided with an arc-shaped baffle plate outside the plurality of heat dissipation holes 102 for shielding, thereby preventing rainwater from entering to a certain extent, when there is a small amount of rain and a slow rain, it is not necessary to shield the plurality of heat dissipation holes 102, so Figure 6, the cooperative setting of the outlet slot 504 and the supplementary rubber block 504 enables a gap to be formed on the left side of the induction box 501, that is, the rainwater entering the induction box 501 can gradually flow out from the gap on the left side. When the rainfall is not heavy, a small amount of rainwater entering the induction box 501 will gradually flow out from the gap at the left end of the induction box 501, so that when the rainfall is small and multiple baffle plates 301 are not needed, the induction box 501 will not slide downward to the extent that it pushes the sliding plate 404 to press on the pressure sensor. When the rainfall is large and urgent, a large amount of rainwater will continuously enter the induction box 501, and the rainwater cannot quickly flow out from the gap on the left side, that is, when the inflow volume is continuously greater than the outflow volume, the induction box 501 will gradually move downward, and then push the sliding plate 404 to press on the pressure sensor to complete the signal transmission operation. After the rainy weather ends, the rainwater in the induction box 501 will gradually flow out from the gap, which is convenient for the device to reset and enables the multiple baffle plates 301 to remove the shielding effect on the multiple heat dissipation holes 102.
[0038] In addition, as an example, as Figure 6 shown, this example solves the problem of facilitating the gradual discharge of rainwater from the induction box 501.
[0039] The inner bottom surface of the induction box 501 described in this device is an inclined plane.
[0040] The setting of the inclined plane enables the rainwater to gradually slide along the bottom surface of the inclined plane inside the induction box 501 after rainwater is poured into the induction box 501, and then gradually flow out from the gap at the left end of the induction box 501, thus facilitating the discharge of rainwater.
[0041] In addition, as an example, as Figure 4-6 shown, this example solves the problem of preventing heavier sundries from falling on the induction box 501 and causing false touches.
[0042] This device also includes a rotating plate 601 rotatably connected to the induction box 501.
[0043] After the gravity of the induction box 501 gradually increases and presses on the sliding plate 404, causing the sliding plate 404 to press on the pressure sensor to send a signal, the rotating plate 601 can be operated to rotate first, and then the rotating plate 601 scrapes the upper surface of the induction box 501, so as to prevent the situation that the induction box 501 slides downward due to heavier sundries falling on the induction box 501, that is, it can avoid false touches caused by other sundries falling instead of rainwater.
[0044] In addition, as an example, as Figure 3-8 shown, this example solves the problem of facilitating the rotation of the rotating plate 601.
[0045] The device also includes a toothed ring 602 fixedly connected to the rotating plate 601, a rack 402 fixedly connected to the slider 401, a first motor fixedly connected to the rectangular frame 201, a first lead screw fixedly connected to the output shaft of the first motor, the first lead screw rotatably connected to the slider 401, an electromagnet 405 slidably connected to the slider 401, an electric push rod II fixedly connected to the slider 401 and capable of pushing the electromagnet 405, and a rubber plug provided at the rotational connection between the rotating plate 601 and the induction box 501.
[0046] After the induction box 501 presses against the sliding plate 404 due to the gradually increasing gravity, operate the telescopic rod of the electric push rod II to move, so that the electromagnet 405 contacts the sliding plate 404. Then, energize the electromagnet 405, so that the electromagnet 405 adsorbs the sliding plate 404. Then, lift the electromagnet 405 upward, so that the sliding plate 404 moves upward, so that the rack 402 and the toothed ring 602 are in the same horizontal position and engage. Then, operate the slider 401 to slide on the rectangular frame 201, so that the rack 402 moves, so that the rack 402 drives the toothed ring 602 to rotate, and then drives the rotating plate 601 to rotate, completing the task of scraping the upper surface of the induction box 501. The setting of the rubber plug can increase the rotational friction of the rotating plate 601, making the rotating plate 601 not easily deviate due to external influence, and thus ensuring that the rack 402 and the toothed ring 602 can engage when at the same height.
[0047] In addition, as an example, such as Figure 1 、 Figure 3 、 Figure 7 shown, this example solves the problem of facilitating the installation of electrical components of two different circuit systems in the same cabinet 101.
[0048] The device also includes a connecting plate 202 fixedly connected to the rectangular frame 201. The connecting plate 202 is provided with a plurality of threaded holes. The rectangular frame 201 is slidably connected to the cabinet 101. A second motor is fixedly connected to the cabinet 101, and a second lead screw is fixedly connected to the output shaft of the second motor. The second lead screw is threadedly connected to the rectangular frame 201.
[0049] When it is necessary to install electrical components of two circuit paths in the same cabinet 101, the electrical components in one system can be installed on the rear side wall of the cabinet 101, and the electrical components in the other system can be installed on the connecting plate 202 through the plurality of threaded holes on the connecting plate 202. Then, when a certain circuit system fails subsequently, the detection range can be quickly narrowed and the maintenance efficiency can be improved;
[0050] At the same time, when installing electrical components, the slider 401 can be operated to slide on the rectangular frame 201 until the slider 401 is offset from the induction box 501, and then the rectangular frame 201 can be operated to slide backward to provide space for installation, which is convenient for the staff to perform installation operations.
[0051] In addition, as an example, Figure 7 As shown, this example solves the problem of accommodating the lines on the rectangular frame 201.
[0052] The device further includes a storage portion 203 fixedly connected to the rectangular frame 201 .
[0053] The staff can place all the circuits connected to the electrical components on the rectangular frame 201 into the storage portion 203 for storage, thereby further separating the circuits of the two circuit systems to facilitate subsequent maintenance tasks.
