Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically, to a layered isolation type high and low voltage complete power distribution cabinet. Background Technology

[0002] High and low voltage switchgear refers to complete sets of electrical equipment used at voltage levels of 380V and below, mainly for the distribution, control and protection of electrical energy.

[0003] Existing complete sets of high and low voltage distribution cabinets are generally composed of multiple cabinets placed side by side. These cabinets contain relays with different functions and can be divided into incoming line cabinets, outgoing line cabinets, tie cabinets, and metering cabinets. The large number of relays inside existing high and low voltage distribution cabinets makes them require frequent maintenance. However, the cabinets of existing high and low voltage distribution cabinets are relatively deep, and the spacing between the relays is small, which makes it inconvenient to perform relay maintenance and plug and unplug lines. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a layered isolation type high and low voltage switchgear to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A layered isolation high and low voltage switchgear includes multiple cabinets arranged in a row.

[0009] Furthermore, the connecting assembly includes a connecting block, which has a plug-in portion and a locking portion. The plug-in portion has a plug-in groove with an upper opening, and the locking portion extends downward and protrudes from the side wall of the mounting plate so that the locking portion can be inserted into the plug-in groove. The locking portion has a locking cavity, and the locking cavity has a locking component, which is used to fix the locking portion in the plug-in groove.

[0010] Furthermore, the locking assembly includes a locking block, an abutment plate, an assembly rod, a first spring, and a driving member. One end of the locking block is slidably extended out of the locking cavity. A through groove for the locking block to be inserted is provided on the side wall opposite to the insertion groove. The abutment plate is fixedly installed on the side wall of the locking block located in the locking cavity. The assembly rod is fixedly installed in the locking cavity and slides through the opposite abutment piece. The first spring is sleeved on the assembly rod. One end of the first spring abuts against the side wall of the locking cavity, and the other end abuts against the abutment piece. The first spring is used to push the abutment piece to drive one end of the locking block to retract into the locking cavity. The driving member is used to drive one end of the locking block to extend out of the locking cavity.

[0011] Furthermore, the driving component includes a mounting post, a second spring, and a driving block. A first inclined surface is provided at one end of the locking block located in the locking cavity. The driving block is slidably installed in the locking cavity. A second inclined surface that cooperates with the first inclined surface is provided on the opposite side wall of the driving block. The mounting posts are arranged opposite to each other. One mounting post is fixedly connected to the side wall of the driving block, and the other mounting post is fixedly installed on the side wall of the locking cavity. The two ends of the second spring are respectively sleeved on the mounting posts. The second spring is used to push the driving block to drive one end of the locking block to extend out of the locking cavity.

[0012] Furthermore, the heat dissipation assembly includes heat dissipation fins and a heat dissipation fan. The heat dissipation fins are located inside the heat dissipation cavity and are fixedly installed on the side wall of the first partition. The heat dissipation fins are used to conduct heat from the cavity into the heat dissipation cavity. The heat dissipation fan is installed on the side wall of the heat dissipation cavity and is used to blow out the heat from the heat dissipation cavity.

[0013] Furthermore, the heat dissipation cavity is provided with an installation strip, and multiple scrapers for scraping dust from the outer sidewalls of the heat dissipation fins are integrally formed on the sidewalls of the installation strip. The heat dissipation cavity is rotatably provided with a second lead screw, which is threaded through the installation strip.

[0014] Furthermore, one end of the rotating shaft extends through the drive cavity. The control assembly includes a drive cylinder, a first friction disc, a second friction disc, a rotating ring, a control rod, and a limiting block. A motor is mounted on the housing. The second friction disc is fixedly mounted on the output end of the motor. A limiting groove is provided on the outer side wall of the extended portion of the rotating shaft. The limiting block is fixedly mounted on the inner side wall of the drive cylinder. The drive cylinder is sleeved outside the extended portion of the rotating shaft. The limiting block extends into the corresponding limiting groove and slides. The rotating ring is rotatably mounted outside the drive cylinder. The first friction disc is fixedly mounted at one end of the drive cylinder. The control rod is fixedly mounted on the outer side wall of the rotating ring. A sliding groove is provided on the upper side wall of the housing for the control rod to extend and slide. The sliding of the control rod causes the first friction disc to press tightly against the second friction disc to realize the rotation of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention controls the drive component inside the cabinet that needs to be repaired to work through the control component, so that the drive component of the cabinet can drive the corresponding two mounting rods to move toward the cavity opening, thereby enabling the mounting rods to drive the mounting plate, mounting piece and the relay mounted on the mounting piece to move toward the cavity opening, thus facilitating repair. 2. In this invention, when the spacing between the mounting pieces on the same mounting plate is small, resulting in a small spacing between the relays on the mounting plate and affecting the maintenance, the mounting pieces can be slidably mounted on the mounting plate to adjust the spacing between adjacent mounting pieces on the same mounting plate, thereby adjusting the spacing between adjacent relays and facilitating the maintenance of the relays.

[0016] 3. In this invention, when the spacing between the mounting plates in the vertical direction is small, the spacing between the relays in the upper and lower rows is also small, which affects the insertion and removal of the circuit. At this time, by sliding the mounting plates on the mounting rod, the spacing between adjacent mounting plates in the vertical direction can be adjusted, thereby increasing the spacing between the relays on the adjacent mounting plates, which facilitates the insertion and removal of the circuit on the relay.

Detailed Implementation

[0033] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0034] Combination Figures 1-15As shown in this embodiment, a layered isolation high and low voltage switchgear includes multiple cabinets 100 arranged in a row. Each cabinet 100 has a cavity. A first partition 501 is provided within the cavity, dividing the cavity on the other side of the first partition 501 into a heat dissipation cavity. A heat dissipation component is provided within the heat dissipation cavity for cooling the cavity. A second partition 403 is provided within the cavity, dividing the cavity below the second partition 403 into a drive cavity. Movable components are provided opposite each other within the cavity. The mounting rod 401 has multiple mounting plates 400 slidably mounted on it. Multiple mounting pieces 502 for mounting relays are slidably mounted on the mounting plates 400. Connecting components are provided on the opposite side walls of the mounting plates 400 to splice adjacent mounting plates 400. A drive component for driving the mounting rod 401 to move is provided in the drive cavity. A housing 200 is provided on the rear side of the multiple cabinets 100. A control component for controlling the drive components in each cabinet to work is provided in the housing 200.

[0035] In actual use, multiple cabinets 100 are arranged side by side in sequence. Since the relays installed in the cabinets 100 have different functions, these cabinets 100 can be divided into incoming line cabinets, outgoing line cabinets, communication cabinets and metering cabinets, etc., to form a complete set of power distribution cabinets. The cavity is divided into layers by the first partition 501 and the second partition 403, which can avoid interference between components in different spaces when they are working. In actual use, the cavity has an opening on one side, and a cabinet door is hinged at the opening. When it is necessary to repair the relay in the cavity, but the cabinet 100 is deep, making the operation inconvenient, the control component controls the drive component inside the cabinet 100 to work. This allows the drive component of the cabinet 100 to drive the two corresponding mounting rods 401 to move toward the opening of the cavity. In turn, the mounting rods 401 can drive the mounting plate 400, the mounting piece 502, and the relay mounted on the mounting piece 502 to move toward the opening of the cavity, thus facilitating repair. When repairing a relay, if the spacing between the mounting pieces 502 on the same mounting plate 400 is small, resulting in a small spacing between the relays on the mounting plate 400 and affecting the repair, the mounting pieces 502 can be slidably mounted on the mounting plate 400 to adjust the spacing between adjacent mounting pieces 502 on the same mounting plate 400. This, in turn, allows for adjustment of the spacing between adjacent relays, thus facilitating relay repair. Specifically, in combination Figures 6-7As shown, in order to achieve the slidable setting of the mounting piece 502 on the mounting plate 400, in this embodiment, the mounting plate 400 is provided with a slot 600 along its length direction, and a threaded post 700 is fixedly installed on the mounting piece 502. The threaded post 700 extends into the slot 600 and is slidably set, so that the mounting piece 502 can be slidably installed on the mounting plate 400. One end of the threaded post 700 is provided with a locking nut 701. By rotating the locking nut 701, it is pressed against the back of the mounting plate 400, thereby fixing the mounting piece 502 on the mounting plate 400. When inserting or removing the circuits on the relays, if the spacing between the mounting plates 400 in the vertical direction is small, the spacing between the relays in the upper and lower rows will be small, affecting the insertion and removal of the circuits. In this case, the mounting plates 400 can be slidably set on the mounting rod 401, so that the spacing between adjacent mounting plates 400 in the vertical direction can be adjusted, thereby increasing the spacing between the relays on adjacent mounting plates 400, which facilitates the insertion and removal of the circuits on the relays. Specifically, in order to enable the mounting plate 400 to be slidably mounted on the mounting rod 401, in this embodiment, the mounting rod 401 is provided with a plurality of positioning holes 503 along its height direction, and the two ends of the mounting plate 400 are integrally formed with positioning parts 601. The mounting rod 401 is slidably mounted through the positioning parts 601, thereby enabling the mounting plate 400 to be slidably mounted on the mounting rod 401. The positioning parts 601 are threaded with positioning bolts, and the positioning bolts are threaded into the positioning holes 503 of the same height, thereby enabling the mounting plate 400 to be fixed on the mounting rod 401. Since the relay generates heat when it is working, in order to prevent the relay from working in a high-temperature environment, in this embodiment, the heat in the cavity is transferred to the heat dissipation cavity through a heat dissipation component, thereby reducing the accumulation of heat in the cavity and thus preventing the relay from working in a high-temperature environment.

[0036] Combination Figure 8 As shown, when the size of the relay to be installed is large, at least two sets of mounting plates 400 are slid according to the size of the relay so that the opposite sidewalls of the two sets of mounting plates 400 can fit together. Then, the two mounting plates 400 are fixed by the connecting assembly so that the two sets of mounting plates 400 can be spliced ​​together. Next, the mounting pieces 502 on the two sets of mounting plates 400 are slid according to the size of the relay so that the corresponding sidewalls of the multiple mounting pieces 502 on the two mounting plates 400 can fit together, so that relays of different sizes can be installed. Combination Figure 9As shown, in this embodiment, the connecting component includes a connecting block 602. The connecting block 602 is provided with a plug-in portion 707 and a locking portion 705. The plug-in portion 707 is provided with a plug-in groove 702 with an upper opening. The locking portion 705 extends downward and protrudes from the side wall of the mounting plate 400 so that the locking portion 705 can be inserted into the plug-in groove 702. The locking portion 705 is provided with a locking cavity, and a locking component is provided in the locking cavity. The locking component is used to fix the locking portion 705 in the plug-in groove 702.

[0037] In actual use, the locking assembly includes a locking block 704, an abutment plate, an assembly rod 904, a first spring 903, and a driving member. One end of the locking block 704 is slidably extended out of the locking cavity. A through groove 703 for the locking block 704 to be inserted is provided on the opposite side wall of the insertion groove 702. The abutment plate is fixedly installed on the side wall of the locking block 704 located in the locking cavity. The assembly rod 904 is fixedly installed in the locking cavity and slides through the opposite abutment piece 902. The first spring 903 is sleeved on the assembly rod 904. One end of the first spring 903 abuts against the side wall of the locking cavity, and the other end abuts against the abutment piece 902. The first spring 903 is used to push the abutment piece 902 to retract one end of the locking block 704 into the locking cavity. The driving member is used to drive one end of the locking block 704 to extend out of the locking cavity. The driving component includes a mounting post 906, a second spring 905, and a driving block 901. A first inclined surface is provided at one end of the locking block 704 located in the locking cavity. The driving block 901 is slidably installed in the locking cavity. A second inclined surface that cooperates with the first inclined surface is provided on the opposite side wall of the driving block 901. The mounting posts 906 are arranged opposite each other. One mounting post 906 is fixedly connected to the side wall of the driving block 901, and the other mounting post 906 is fixedly installed on the side wall of the locking cavity. The two ends of the second spring 905 are respectively sleeved on the mounting post 906. The second spring 905 is used to push the driving block 901 to drive one end of the locking block 704 to extend out of the locking cavity.

[0038] In actual use, a column 706 is fixedly connected to the side wall of the drive block 901, and a long groove is provided on the locking part 705 for the column 706 to extend and slide. The elastic force of the second spring 905 is greater than the elastic force of the two first springs 903, so that in the initial state, the second spring 905 pushes the drive block 901 to move, so that the second inclined surface can fit and squeeze the first inclined surface, so that the two first inclined surfaces can extend the corresponding locking blocks 704 out of the locking cavity. During the splicing of two mounting plates 400, the drive block 901 is slid by the column 706, so that the second inclined surface on the drive block 901 can move away from the first inclined surface and compress the second spring 905. At this time, under the action of the first spring 903 pushing the abutment plate, the two locking blocks 704 can retract into the locking cavity. Then, one of the mounting plates 400 is slid so that the locking part 705 of the mounting plate 400 can be inserted into the insertion groove 702 on the other mounting plate 400. When the bottom wall of the locking part 705 abuts against the bottom wall of the insertion groove 702, the column 706 is released, so that under the action of the second spring 905, the locking block 704 can extend out of the locking cavity and insert into the through groove 703, thereby enabling the two mounting plates 400 to be spliced. It should be noted that the sidewalls of the locking block 704 and the driving block 901 slide against the corresponding sidewalls of the locking cavity, thereby enabling the locking block 704 and the driving block 901 to be slidably installed.

[0039] Combination Figures 4-5 As shown, in order to achieve the sliding installation of the mounting rod 401 in the cavity, in this embodiment, a slide rail 500 is fixedly provided on the top wall of the cavity, a first slider is provided at the upper end of the mounting rod 401, the first slider is slidably installed on the corresponding slide rail 500, a slide groove 402 communicating with the drive cavity is provided on the second partition plate 403, and a second slider 1000 is provided at the lower end of the mounting rod 401, the second slider 1000 is slidably installed in the slide groove 402.

[0040] In actual use, the slide rail 500 is T-shaped, and the first slider is provided with a track groove that matches the slide rail 500 and is also T-shaped, so that the upper end of the mounting rod 401 can be slidably installed. The second slider 1000 is I-shaped, and the opposite side wall of the slide groove 402 extends into the second slider 1000, so that the second slider 1000 can be slidably installed in the slide groove 402, so that the lower end of the mounting rod 401 can be slidably installed, thereby allowing the mounting rod 401 to be slidably installed in the cavity.

[0041] Combination Figure 10As shown, in this embodiment, the driving assembly includes a driving plate 1001, a first lead screw 1011, a first bevel gear 1010, a second bevel gear 1009, a third bevel gear 1007, a fourth bevel gear 1006, a rotating rod 1008, and a rotating shaft 1002. The driving plate 1001 is fixedly connected to the lower side wall of the second slider 1000. The first lead screw 1011 is rotatably mounted in the driving cavity and aligned with the corresponding slide groove 402. The first lead screw 1011 is threaded through the corresponding driving plate 1001. The first bevel gear 1010 is fixedly sleeved on the first lead screw 1009. On the drive cavity, a rotating rod 1008 is rotatably mounted. A second bevel gear 1009, which meshes with the corresponding first bevel gear 1010, is fixedly mounted on the rotating rod 1008. A third bevel gear 1007 is also fixedly mounted on the rotating rod 1008. A rotating shaft 1002 is rotatably mounted in the drive cavity. A fourth bevel gear 1006, which meshes with the third bevel gear 1007, is fixedly mounted on the rotating shaft 1002. The control component controls the rotating shaft 1002 in the corresponding cabinet 100 to rotate, so as to realize the movement of the drive plate 1001 on the corresponding first lead screw 1011.

[0042] In actual use, this embodiment controls the rotation of the rotating shaft 1002 inside the cabinet 100 that needs maintenance through the control component. This causes the rotating shaft 1002 to drive the fourth bevel gear 1006 to drive the third bevel gear 1007 and the rotating rod 1008 to rotate. In turn, the rotating rod 1008 drives the two second bevel gears 1009 to drive the corresponding two first bevel gears 1010 and the first lead screw 1011 to rotate. The sliding groove 402 limits and guides the second slider 1000, thereby enabling the first lead screw 1011 to drive the two drive plates 1001 to move the corresponding second slider 1000 and the mounting rod 401.

[0043] Combination Figures 10-15As shown, in this embodiment, one end of the rotating shaft 1002 extends through the drive cavity. The control assembly includes a drive cylinder 1003, a first friction disc 1004, a second friction disc, a rotating ring 1005, a control rod 201, and a limiting block 1500. A motor 203 is mounted on the housing 200. The second friction disc is fixedly mounted on the output end of the motor 203. A limiting groove 1501 is provided on the outer side wall of the extended portion of the rotating shaft 1002. The limiting block 1500 is fixedly mounted on the inner side wall of the drive cylinder 1003. The drive cylinder 1003 is sleeved on the rotating shaft. Outside the extended portion of 1002, the limiting block 1500 extends into the corresponding limiting groove 1501 and slides. The rotating ring 1005 is rotatably mounted outside the drive cylinder 1003. The first friction disc 1004 is fixedly mounted at one end of the drive cylinder 1003. The control rod 201 is fixedly mounted on the outer side wall of the rotating ring 1005. The upper side wall of the housing 200 is provided with a sliding groove for the control rod 201 to extend and slide. The control rod 201 slides and drives the first friction disc 1004 to press tightly against the second friction disc to realize the rotation of the rotating shaft 1002.

[0044] In actual use, when it is necessary to move the mounting rod 401, the control rod 201 is first slid along the sliding groove, so that it can drive the rotating ring 1005 to move the driving cylinder 1003 and the first friction disk 1004 toward the second friction disk. When the first friction disk 1004 is in close contact with the second friction disk, the second friction disk is driven to rotate by the motor 203, so that the second friction disk can drive the first friction disk 1004 to drive the driving cylinder 1003 to rotate. Through the cooperation of the limiting block 1500 and the limiting groove 1501, the driving cylinder 1003 can drive the rotating shaft 1002 to rotate. It should be noted that the number of the second friction discs is the same as the number of the cabinet 100. Two motors 203 are installed on the housing 200. Only two of the second friction discs are installed on the output end of the motors 203, while the rest are rotatably installed inside the housing 200. These second friction discs are connected by synchronous pulleys and synchronous belts, so that these second friction discs can rotate synchronously.

[0045] Combination Figures 2-12 As shown, in this embodiment, the heat dissipation assembly includes heat dissipation fins 1100 and a heat dissipation fan 204. The heat dissipation fins 1100 are located inside the heat dissipation cavity and are fixedly installed on the side wall of the first partition 501. The heat dissipation fins 1100 are used to introduce heat from the cavity into the heat dissipation cavity. The heat dissipation fan 204 is installed on the side wall of the heat dissipation cavity and is used to blow out the heat from the heat dissipation cavity.

[0046] In actual use, the cabinet 100 is provided with an air inlet 101 that communicates with the heat dissipation cavity, so that when the cooling fan 204 blows out the heat in the heat dissipation cavity, the outside air can enter the heat dissipation cavity, thereby allowing the air to circulate in the heat dissipation cavity and making the heat dissipation effect better. To prevent dust from the outside air from entering the heat dissipation cavity and causing dust to accumulate on the heat dissipation fins 1100, thus reducing their thermal conductivity, this embodiment includes an installation strip 1200 inside the heat dissipation cavity. Multiple scrapers 1201 are integrally formed on the sidewall of the installation strip 1200 for scraping dust from the outer sidewall of the heat dissipation fins 1100. A second lead screw 1202 is rotatably mounted inside the heat dissipation cavity. The second lead screw 1202 is threaded through the installation strip 1200, and its lower end extends through the second partition 403 into the drive cavity. A fifth bevel gear 1302 is fixedly mounted at the lower end of the second lead screw 1202. A drive shaft 1300 is rotatably mounted inside the drive cavity, and a sixth bevel gear 1301 meshing with the fifth bevel gear 1302 is rotatably mounted on the drive shaft 1300. The rotation of the drive shaft 1300 drives the installation strip 1200 to move up and down.

[0047] In actual use, one end of the drive shaft 1300 extends out of the drive cavity. The extended end of the drive shaft 1300 is also equipped with the same components as the extended end of the rotating shaft 1002 (i.e., drive cylinder 1003, first friction disc 1004, second friction disc, rotating ring 1005, control rod 201, limit block 1500), which enables the drive shaft 1300 to rotate. This allows the sixth bevel gear 1301 to drive the fifth bevel gear 1302 and the second lead screw 1202 to rotate. The rotation of the second lead screw 1202 can drive the mounting strip 1200 and scraper 1201 to rise and fall, so that the scraper 1201 can scrape off the dust on the heat sink fins 1100. The heat dissipation cavity has an opening on one side, and a side plate is provided at the opening position. The opening allows the dust scraped off by the scraper 1201 to be removed from the heat dissipation cavity. In order to ensure that the mounting strip 1200 can be raised and lowered smoothly, in this embodiment, a guide rod is fixedly installed inside the heat dissipation cavity. The guide rod slides through the mounting strip 1200, and the mounting strip 1200 can be raised and lowered smoothly through the guiding effect of the guide rod.

[0048] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
