Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet device that is easy to install. Background Art

[0002] In modern power distribution systems, distribution cabinets, as the core carrier of the final distribution equipment and motor control center, undertake important functions such as power distribution, circuit control and protection. Distribution cabinets are divided into two types according to the installation environment: indoor and outdoor. Among them, outdoor distribution cabinets are more widely used because they need to meet the power supply needs of complex outdoor environments.

[0003] From the perspective of power distribution component installation, a large number of electrical components such as circuit breakers, contactors, and relays usually need to be installed inside the power distribution cabinet. In some complex installation scenarios, installers are even required to enter the cabinet to operate. However, many current power distribution cabinets with limited space still use traditional cabinet door designs with two-way opening or fixed-direction one-way opening. During the installation of electrical components, the cabinet doors will occupy a large amount of operating space, and there will be spatial interference between the cabinet doors and the installers or the components to be installed, making it difficult for installers to operate flexibly. Especially in a narrow cabinet, the frequent opening and closing of the cabinet doors seriously hinders the precise positioning and fixation of the components, greatly reducing the installation efficiency and extending the construction period.

[0004] When installing and fixing the distribution cabinet, in order to meet the requirements of moisture-proof and corrosion-proof, both large and small distribution cabinets are usually installed off the ground through mounting frames. However, the outdoor environment is complex and changeable, and the flatness of the ground varies greatly. There are slopes, unevenness, and accumulation of gravel. The mounting frame of the traditional distribution cabinet is simple in structure and lacks effective horizontal adjustment function, making it difficult to adapt to complex terrain. Once the distribution cabinet cannot be installed horizontally, it will not only cause uneven force on the cabinet body and accelerate damage to the cabinet structure, but also increase the risk of tipping, causing problems such as loose lines and component falling off, which will cause power failures and affect the stability and safety of regional power supply. Summary of the Invention

[0005] The present invention provides a power distribution cabinet device that is easy to install, so as to solve the problem that the existing power distribution cabinet cannot meet the installation requirements.

[0006] The present invention provides a conveniently installed power distribution cabinet device that adopts the following technical solutions:

[0007] A power distribution cabinet device that is easy to install comprises a cabinet body, a bracket and a control panel.

[0008] The cabinet body has an installation cavity inside, and the cabinet body is provided with an installation opening connecting the external environment and the installation cavity. The cabinet body is provided with a blocking door, and the blocking door can block the installation opening. Connecting parts are provided on the two vertical edges of the blocking door, and any one of the connecting parts can serve as a hinge point between the blocking door and the cabinet body; the bracket includes a support plate and a plurality of legs, and the support plate is fixedly connected to the lower end surface of the cabinet body, and each leg can be telescopically arranged. The plurality of legs are evenly distributed around the circumference of the support plate, and each leg includes a fixed part and a telescopic part, one end of the fixed part is fixedly connected to the support plate, and the fixed part is hollow inside, and one end of the telescopic part is slidably inserted into the fixed part; the adjustment control is used to adjust the length of each leg according to the pressure borne by each leg, so that the support plate is in a horizontal state.

[0009] Furthermore, the adjustment control unit includes a sensing block and a balancing mechanism, and there are multiple sensing blocks, each of which is fixed on one of the legs. Each sensing block is hollow inside, and a partition plate is provided inside the sensing block. The partition plate divides the interior of the sensing block into a relatively isolated first chamber and a second chamber; during the shortening of the legs, the air pressure in the first chamber can gradually rise; the balancing mechanism is used to connect the second chambers of multiple sensing blocks, and the balancing mechanism is used to prevent the shortening of the legs when the air pressure in the first chamber is greater than the air pressure in the second chamber.

[0010] Furthermore, an elastic plate is coaxially fixed inside the fixed part, and the elastic plate is initially in a downwardly raised state. A plurality of air holes are provided on the elastic plate running through the upper and lower parts. The elastic plate separates the fixed part into a third chamber and a fourth chamber. The end of the telescopic part is provided in the third chamber, and the fourth chamber is always connected to the external environment. When the length of the support leg decreases, the telescopic part slides relative to the fixed part, the elastic plate can be deformed, and the aperture of the air hole gradually decreases, so that the air pressure in the third chamber gradually increases, and the third chamber is connected to the first chamber through a first conduit.

[0011] Furthermore, the balancing mechanism includes a fixed block and a plurality of second conduits, the fixed block is fixedly connected to the support plate, the interior of the fixed block is hollow, and each second conduit connects the interior of the fixed block with one of the second chambers.

[0012] Furthermore, the fixed block is provided with a pressure relief hole connecting the internal environment and the external environment, and the fixed block is provided with a sealing ring. The sealing ring is initially set to be in a state of sealing the pressure relief hole. When the support plate is in a horizontal state, the sealing ring unblocks the pressure relief hole.

[0013] Furthermore, the balancing mechanism also includes a limiting frame, a limiting rod and a limiting torsion spring, the limiting rod is connected to the fixed part, the partition plate is fixedly connected to the rotating shaft, and the partition plate can rotate around the rotating shaft inside the sensing block; the limiting torsion spring is sleeved on the rotating shaft, one end of the limiting torsion spring is fixedly connected to the partition plate, the limiting frame is fixedly connected to the end of the limiting torsion spring, the limiting frame and the partition plate are arranged coplanar, the limiting frame has a first state of abutting the limiting rod, and the limiting frame also has a second state of abutting the lower end of the fixed part. Initially, the limiting frame abuts the limiting rod. At this time, the limiting frame and the partition plate are in a horizontal state. When the air pressure in the first chamber is greater than the air pressure in the second chamber, the limiting frame changes from the first state to the second state. When the limiting frame is in the second state, the limiting frame prevents the fixed part and the telescopic part from sliding relative to each other.

[0014] Furthermore, an adjusting rod is provided on the telescopic part, and the adjusting rod is threadedly connected to the telescopic part. The adjusting rod can abut against the lower end surface of the fixed part. When the adjusting rod abuts against the lower end surface of the fixed part, the limiting rod can rotate on the fixed part, so that the limiting frame is transformed from the first state to the second state under the action of the limiting torsion spring.

[0015] Furthermore, a plurality of pushing cylinders are provided inside the fixed block, each of the pushing cylinders is connected to one of the first chambers, a driving disk is slidingly provided inside the fixed block, and the driving disk is fixedly connected to the sealing ring.

[0016] Furthermore, an annular groove is provided on the driving disk, and a plurality of limiting balls are provided in the annular groove. The plurality of limiting balls can prevent the second pushing cylinder from entering the annular groove.

[0017] Furthermore, a third conduit is provided between the third chamber and the second chamber, and a control valve is provided on the third conduit, and the control valve can control the conductivity of the third conduit.

[0018] The beneficial effects of the present invention are: a power distribution cabinet device that is easy to install according to the present invention includes a cabinet body, a bracket and an adjustment control unit. When producing the power distribution cabinet, in order to facilitate the staff to install electrical components inside the power distribution cabinet, two connecting parts are set at the positions of the two vertical edges of the blocking door to connect the connecting parts to the cabinet body.

When installing a distribution cabinet in an outdoor environment, the ground environment is complex and changeable. In order to ensure that the distribution cabinet is in a horizontal state after installation, the legs are set to a retractable structure during the production process of the distribution cabinet. When multiple legs touch the ground at the same time, the cabinet body is in a tilted state due to the uneven ground. At this time, the pressures borne by the multiple legs are different, and the cabinet body is at risk of tipping over. The adjustment control can adjust the length of each leg according to the pressure borne by each leg, so that the pressures borne by multiple legs are the same, thereby adjusting the support plate to a horizontal state, thereby meeting various installation requirements of the distribution cabinet.

[0037] like Figures 1 to 13 As shown, an embodiment of the present invention provides a power distribution cabinet device that is easy to install, which includes a cabinet body 110, a bracket and a control unit.

[0038] The interior of the cabinet 110 is hollow, and the hollow chamber inside the cabinet 110 is the installation cavity 111. The side wall of the cabinet 110 is provided with an installation port that connects the external environment and the installation cavity 111. The staff can install electrical components into the cabinet 110 through the installation port. A blocking door 120 is provided on the cabinet 110, and the blocking door 120 can block the installation port. Specifically, two connecting parts are provided on the two vertical edges of the blocking door 120, and any one of the connecting parts can serve as a hinge point between the blocking door 120 and the cabinet 110. In this embodiment, the connecting part includes a hinge rod 121, the middle part of the hinge rod 121 is fixedly connected to the blocking door 120, and the upper and lower ends of the hinge rod 121 are separated from the blocking door 120. The cabinet body 110 is provided with a first fixing sleeve 130 and a second fixing sleeve 140, the first fixing sleeve 130 has a first opening, the first fixing sleeve 130 is fixedly connected to the cabinet body 110, and two first fixing sleeves 130 are provided, and the two first fixing sleeves 130 are distributed on both sides of the installation opening; the second fixing sleeve 140 is provided with two, each second fixing sleeve 140 is corresponding to a first fixing sleeve 130, the outer diameter of the second fixing sleeve 140 is equal to the inner diameter of the first fixing sleeve 130, the inner diameter of the second fixing sleeve 140 is equal to the outer diameter of the hinge rod 121, the second fixing sleeve 140 has a second opening, and the second fixing sleeve 140 can be relatively The first fixing sleeve 130 is coaxially rotated. When the blocking door 120 is used to block the installation opening, the two hinged rods 121 are both installed inside the second fixing sleeve 140, and the first opening is blocked by the second fixing sleeve 140, and the second opening is blocked by the first fixing sleeve 130, thereby preventing the hinged rod 121 from detaching from the second fixing sleeve 140. When the installation opening needs to be opened, according to the actual conditions of the installation site, one of the second fixing sleeves 140 is adjusted to rotate inside the first fixing sleeve 130 so that the first opening corresponds to the second opening, thereby ensuring that the hinged rod 121 can detach from the second fixing sleeve 140.

[0039] The bracket includes a support plate 210 and a plurality of legs 220. The support plate 210 is fixedly connected to the lower end surface of the cabinet body 110. The outline of the support plate 210 is the same size as the outline of the lower end surface of the cabinet body 110. The support plate 210 and the lower end surface of the cabinet body 110 can be fixedly connected by bolts. When the power distribution cabinet is produced, the cabinet body 110 and the bracket can be processed separately, which is convenient for transporting the accessories of the power distribution cabinet. One end of the plurality of legs 220 is fixedly connected to the lower end surface of the support plate 210. Each leg 220 can be telescopically arranged. The plurality of legs 220 are evenly distributed around the circumference of the support plate 210. In this embodiment, the support plate 210 is rectangular and has four legs 220. The four legs 220 are respectively arranged at the four corners of the support plate 210. Each leg 220 includes a fixed portion 221 and a telescopic portion 222. One end of the fixed portion 221 is fixedly connected to the support plate 210. The fixed portion 221 is hollow inside, and one end of the telescopic portion 222 is slidably inserted into the fixed portion 221. In the initial state, the four legs 220 are of equal length. When the telescopic portions 222 of the four legs 220 all touch the ground, the support plate 210 is tilted due to the uneven ground. When the cabinet 110 is installed on the support plate 210, there is a risk of the cabinet 110 tipping over. At this time, the gravity of the cabinet 110 exerts different pressures on different legs 220. The adjustment control is used to adjust the length of each leg 220 according to the pressure borne by each leg 220, so that the support plate 210 is in a horizontal state. After the adjustment control adjusts the lengths of multiple legs 220, the support plate 210 is transformed into a horizontal state. When the cabinet body 110 is installed on the support plate 210, the stability of the cabinet body 110 is improved, thereby meeting the installation requirements of the distribution cabinet.

[0040] The present invention provides a power distribution cabinet device that is easy to install, which includes a cabinet body 110, a bracket and an adjustment control unit. When producing the power distribution cabinet, in order to facilitate the staff to install electrical components inside the power distribution cabinet, two connecting parts are set at the positions of the two vertical edges of the blocking door 120, and the connecting parts are connected to the cabinet body 110. In actual application, according to the actual installation site of the power distribution cabinet, the staff can use any one of the connecting parts as the hinge point, and the blocking door 120 can be rotated with the hinge point as the rotating axis, so that the staff can install the electrical components inside the cabinet body 110 through the installation port. When the distribution cabinet is installed in an outdoor environment, the ground environment is complex and changeable. In order to ensure that the distribution cabinet is in a horizontal state after installation, the legs 220 are set to a retractable structure during the production process of the distribution cabinet. When multiple legs 220 touch the ground at the same time, the cabinet body 110 is in a tilted state due to the uneven ground. At this time, the pressures borne by the multiple legs 220 are different, and the cabinet body 110 is at risk of tipping over. The adjustment control can adjust the length of each leg 220 according to the pressure borne by each leg 220, so that the pressures borne by the multiple legs 220 are the same, thereby adjusting the support plate 210 to a horizontal state, thereby meeting various installation requirements of the distribution cabinet.

[0041] In one embodiment, the adjustment control unit includes a sensing block 230 and a balancing mechanism. A plurality of sensing blocks 230 are provided, and each sensing block 230 is fixedly provided on a support leg 220. Specifically, the sensing block 230 is fixedly provided on the telescopic portion 222 of the support leg 220. The interior of the sensing block 230 is hollow, and the interior of the sensing block 230 is semi-circular. A partition plate 240 is provided inside the sensing block 230. The partition plate 240 divides the interior of the sensing block 230 into a relatively isolated first chamber 231 and a second chamber 232. In the initial state, the partition plate 240 is in a horizontal state, wherein the first chamber 231 is above the second chamber 232. When the cabinet body 110 is installed on the support plate 210, the cabinet body 110 squeezes the multiple legs 220 at the same time, causing the multiple legs 220 to shorten at the same time. However, since the ground is in an uneven state, the pressure on different legs 220 is different, and the leg 220 at the lowest position on the ground is subjected to the greatest pressure. Accordingly, the leg 220 is compressed the slowest. During the actual installation process, the leg 220 with the slowest compression speed is defined as the reference leg. In the sensing block 230 set on the reference leg, the first chamber 231 and the second chamber 232 are always connected.

[0042] During the shortening process of all the legs 220, the air pressure in the first chamber 231 can gradually increase. Specifically, an elastic plate 310 is coaxially fixed inside the fixing portion 221. The elastic plate 310 is initially in a downwardly bulging arc. The elastic plate 310 is provided with a plurality of air holes running through the upper and lower parts. In the initial state, the aperture of the air holes is at the largest state. The elastic plate 310 divides the interior of the fixing portion 221 into a third chamber 320 and a fourth chamber 330. The fourth chamber 330 is above the third chamber 320. The air holes connect the third chamber 320 and the fourth chamber 330. The side wall of the fixing portion 221 is provided with a through hole connecting the external environment and the fourth chamber 330, so that the fourth chamber 330 is always in an atmospheric pressure state. One end of the telescopic portion 222 is slidably disposed within the third chamber 320. As the telescopic portion 222 slides relative to the fixed portion 221, the gas within the third chamber 320 flows through the vent holes into the fourth chamber 330. During this process, the elastic plate 310 gradually deforms upward, causing the aperture of the vent holes to gradually decrease, thereby gradually increasing the pressure within the third chamber 320. Furthermore, the leg 220 at the lowest point on the ground experiences the greatest pressure, causing it to compress the slowest. A first conduit 340 is provided on the sidewall of the fixed portion 221. This first conduit 340 connects the third chamber 320 with the first chamber 231, ensuring that the air pressure within the first chamber 231 gradually increases as the leg 220 contracts.

[0043] The balancing mechanism is used to connect the second chambers 232 of the multiple sensing blocks 230. It is also used to prevent the leg 220 from shortening when the air pressure in the first chamber 231 is greater than the air pressure in the second chamber 232. When multiple legs 220 shorten simultaneously, the reference leg shortens at the slowest rate, and the first chamber 231 and second chamber 232 of the reference leg are interconnected. At this point, the air pressure in the first and second chambers 231, 232 of the reference leg increases simultaneously, while the air pressure in the first chamber 231 of the other legs 220 increases slowly. The balancing mechanism connects the multiple second chambers 232. During the shortening of the other legs 220, the air pressure in the first chamber 231 will always exceed the air pressure in the second chamber 232. At this point, the balancing mechanism prevents further shortening of that leg 220. In the reference leg, staff manually adjust the minimum length to ensure that the reference leg and the other legs 220 are subjected to the same pressure, at which point the support plate 210 is horizontal.

[0044] In one embodiment, the balancing mechanism includes a fixed block 410 and multiple second conduits 420. The fixed block 410 is fixedly connected to the support plate 210 and is hollow. Each second conduit 420 connects the interior of the fixed block 410 to a second chamber 232. In the sensing block 230 mounted on the reference leg, the air pressure within the second chamber 232 is the same as the air pressure within the first chamber 231. The air pressure within the second chamber 232 is transmitted through the fixed block 410 and the multiple second conduits 420, thereby maintaining interconnectedness among the multiple second chambers 232.

[0045] In one embodiment, the fixed block 410 is provided with a pressure relief hole 430 that passes through its side wall. The pressure relief hole 430 connects the external environment with the interior of the fixed block 410. The fixed block 410 is provided with a sealing ring 440. The sealing ring 440 can seal the pressure relief hole 430. In the initial state, the sealing ring 440 is set to be in a state of sealing the pressure relief hole 430. During the shortening process of the legs 220, when at least three legs 220 (including the reference leg) stop shortening, it proves that the support plate 210 is in a horizontal state. In the other legs 220 except the reference leg, the second chamber 232 The air pressure in the second chamber 232 is lower than the air pressure in the first chamber 231. At this time, the sealing ring 440 releases the blocking of the pressure relief hole 430, so that the air pressure in the multiple second chambers 232 returns to the atmospheric pressure state. Since the first chamber 231 and the third chamber 320 are in a connected state, the third chamber 320 and the fourth chamber 330 are connected through the air vent. Although the aperture of the air vent is small, when the support plate 210 is in a horizontal state, the air pressure in the second chamber 232 returns to the atmospheric pressure state, and the air pressure in the first chamber 231 gradually decreases to the atmospheric pressure state, so that the support plate 210 is in a stable state.

[0046] In one embodiment, the balancing mechanism further includes a limiting frame 510, a limiting rod 520, and a limiting torsion spring 530. The limiting rod 520 is connected to the fixing portion 221, and the limiting rod 520 is arranged parallel to the axis of the fixing portion 221. A rotating shaft is fixedly provided on the partition plate 240, and the rotating shaft is rotatably connected to the sensing block 230, so that the partition plate 240 can rotate inside the sensing block 230. In the initial state, the partition plate 240 is in a horizontal state, and the interior of the sensing block 230 is alternately semi-annular, ensuring that the partition plate 240 can still rotate inside the sensing block 230 when dividing the interior of the sensing block 230 into the first chamber 231 and the second chamber 232.

[0047] The limiting torsion spring 530 is mounted on the rotating shaft. One end of the limiting torsion spring 530 is fixedly connected to the partition plate 240. The limiting frame 510 has a U-shaped profile and is fixedly connected to the other end of the limiting torsion spring 530. The limiting frame 510 is always coplanar with the partition plate 240. When the partition plate 240 rotates inside the sensing block 230, the limiting frame 510 rotates outside the sensing block 230. In the initial state, the partition plate 240 is horizontal and the limiting frame 510 is in contact with the limiting rod 520. Friction between the limiting frame 510 and the limiting rod 520 causes the limiting frame 510 and the partition plate 240 to be stationary. Furthermore, the limiting frame 510 has a first state in which it abuts the limiting rod 520 and a second state in which it abuts the lower end of the fixing portion 221. Initially, the limiting frame 510 abuts the limiting rod 520, and the limiting frame 510 and the partition plate 240 are in a horizontal state. Furthermore, the limiting torsion spring 530 is in a stored force state in the initial state. When the limiting torsion spring 530 releases the force, the limiting frame 510 can be transformed from the first state to the second state. When the air pressure in the first chamber 231 is greater than the air pressure in the second chamber 232, the limiting frame 510 is transformed from the first state to the second state. When the limiting frame 510 is in the second state, there is friction between the limiting frame 510 and the lower end of the fixed part 221, and the limiting frame 510 hinders the relative sliding of the fixed part 221 and the telescopic part 222, thereby ensuring that when the support plate 210 is in a horizontal state, the fixed part 221 no longer slides relative to the telescopic part 222.

[0048] In one embodiment, an adjusting rod 540 is provided on the telescopic part 222, and the adjusting rod 540 is arranged parallel to the axis of the telescopic part 222. The lower end of the adjusting rod 540 is threadedly connected to the telescopic part 222. In the initial state, the upper ends of multiple adjusting rods 540 are in the same horizontal plane. The staff can rotate the adjusting rod 540 to change the height of the upper end of the adjusting rod 540. When the telescopic part 222 slides relative to the fixed part 221, the upper end of the adjusting rod 540 can abut the lower end surface of the fixed part 221. When the adjusting rod 540 abuts the lower end surface of the fixing portion 221, the limiting rod 520 can rotate on the fixing portion 221. Specifically, a trigger block is provided at the lower end of the fixing portion 221, and the limiting rod 520 is rotatably connected to the lower end of the fixing portion 221. A limiting groove is provided on the limiting rod 520, and the trigger block slides vertically and is connected to the fixing portion 221, so that the trigger block can enter the limiting groove. When the trigger block is in the limiting groove, the limiting rod 520 cannot rotate on the fixing portion 221. When the adjusting rod 540 abuts the lower end surface of the fixing portion 221, the adjusting rod 540 can push the trigger block so that the trigger block is out of the limiting groove. At this time, the limiting rod 520 can rotate at the lower end of the fixing portion 221. When the limiting rod 520 can rotate at the lower end of the fixing portion 221, under the action of the limiting torsion spring 530, the limiting frame 510 can be transformed from the first state to the second state. Furthermore, the staff does not rotate all the adjustment rods 540, but rotates the adjustment rod 540 connected to the reference leg. When the support plate 210 is in a horizontal state, the length of the reference leg is in the longest state. By rotating the adjustment rod 540 on the reference leg, it is ensured that the limiting frame 510 on the reference leg can be smoothly transformed from the first state to the second state.

[0049] In one embodiment, a plurality of pushing cylinders 550 are provided inside the fixed block 410, and the interior of each pushing cylinder 550 is connected to a first chamber 231. Specifically, a plurality of fourth conduits 580 are provided on the fixed block 410. The pushing cylinder 550 includes a cylinder body and a cylinder shaft. The interior of the cylinder body is hollow, and one end of the cylinder shaft is slidably arranged inside the cylinder body. The cylinder body and the cylinder shaft are both vertically arranged. The fourth conduit 580 connects the first chamber 231 with the interior of the cylinder body. When the air pressure outside the cylinder body is greater than the air pressure inside the cylinder body, the length of the cylinder body is in the shortest state. When the air pressure inside the cylinder body is greater than the air pressure outside the cylinder body, the cylinder body gradually extends. A driving disk 590 is slidingly provided inside the fixed block 410, and the driving disk 590 is fixedly connected to the sealing ring 440. When the air pressure inside the fixed block 410 is lower than the air pressure inside the pushing cylinder 550, the pushing cylinder 550 can extend, and the pushing cylinder 550 can push the driving disk 590 when extending. When both pushing cylinders 550 are in an extended state, the driving disk 590 moves relative to the fixed block 410, so that the sealing ring 440 releases the pressure relief hole 430, and the air pressure in the multiple second chambers 232 returns to the atmospheric pressure state, thereby ensuring that the length of the multiple legs 220 remains stable.

[0050] In one embodiment, an annular groove is provided on the driving disk 590, and a plurality of limiting balls 570 are provided in the annular groove. In this embodiment, the plurality of limiting balls 570 are arranged around the circumferential direction of the annular groove, and there is also a gap for the limiting balls 570 in the annular groove. When one of the pushing cylinders 550 is extended, the pushing cylinder 550 can smoothly enter the annular groove. When the second pushing cylinder 550 is extended, the second pushing cylinder 550 cannot enter the annular groove. The second pushing cylinder 550 pushes the driving disk 590, so that the driving disk 590 slides relative to the fixed block 410.

[0051] In one embodiment, a third conduit 450 is provided between the third chamber 320 and the second chamber 232. A control valve is provided on the third conduit 450. The control valve can control the conductivity of the third conduit 450. The staff can conduct the third conduit 450 provided on the reference leg, and the staff controls the third conduits 450 on other legs 220 to be in a blocked state, thereby ensuring that the first chamber 231 and the second chamber 232 on the reference leg are in a mutually conductive state.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
