Description

Technical Field

[0001] The present application relates to the technical field of low-voltage switch cabinets, and in particular to a low-voltage switch cabinet with adjustable partition volume. Background Art

[0002] Low-voltage switchgear is a device used for power system control, protection and distribution. The cabinet contains various electrical components, such as circuit breakers, contactors, fuses, relays, etc. Different components are placed in different areas in the cabinet. These components work together to achieve safe and stable operation of the power system. The modular design of low-voltage switchgear makes its installation and maintenance more convenient. It is widely used in industrial, commercial and residential fields and is an indispensable and important part of the power system.

[0003] In the actual use of low-voltage switchgear, in addition to the electrical components mentioned above, additional devices such as power meters and communication modules can be configured according to needs to achieve remote monitoring and management. In low-voltage switchgear, components of different specifications and different quantities are selected according to actual needs. The volume of the partitions in common low-voltage switchgear cannot be adjusted, which will waste the internal space of the switchgear. Utility Model Content

[0004] In order to address the problem of wasted internal space in a switch cabinet and improve the adaptability of the switch cabinet to built-in components of different specifications and quantities, the present application provides a low-voltage switch cabinet with adjustable partition volume.

[0005] The present application provides a low-voltage switch cabinet with adjustable partition volume, which adopts the following technical solution:

[0006] A low-voltage switch cabinet with adjustable partition volume, comprising a cabinet body, a cabinet door rotatably connected to one side of the cabinet body, vertical guide rails respectively arranged on both sides of the upper and lower ends of the cabinet body, a mounting frame slidably connected between the upper and lower adjacent vertical guide rails, and a pull-out plate slidably connected to one side of the mounting frame, wherein the mounting frame is provided with a plurality of sliding grooves for the pull-out plates to be inserted and slidably spaced apart along the height direction, and the two sides of the pull-out plates are respectively inserted into the sliding grooves on the adjacent two sides arranged on the same layer.

[0007] By adopting the above technical scheme, the pull-out plate can be inserted into the sliding grooves of different layers according to actual needs to adjust the installation height of the pull-out plate to adapt to the assembly requirements of electrical components of different numbers and specifications. When installing electrical components, the mounting frame can be pulled out as a whole for easy operation; the pull-out plate cooperates with the pull-out mounting frame to improve the ease and practicality of using the low-voltage switch cabinet.

[0008] Optionally, the mounting frame is provided with a transverse guide rail at the sliding groove for the side of the pull-out plate to be inserted and slide, and the transverse guide rail is rotatably connected to one end close to the cabinet door and is used to close the transverse guide rail.

[0009] By adopting the above technical solution, the setting of the transverse guide rail improves the flexibility of pulling out the pull-out plate, and when the pull-out plate is placed at the target height, the baffle can be rotated to close the outlet end of the transverse guide rail to prevent the pull-out plate from partially sliding out of the outlet end of the transverse guide rail, thereby reducing the impact on electrical components and circuits.

[0010] Optionally, the baffle includes a rotating part and a blocking part connected up and down, and one end of the transverse guide rail is provided with a square groove for the rotating part to be inserted and rotatably connected, and the groove wall of the square groove restricts the rotating part from turning down spontaneously.

[0011] By adopting the above technical solution, the square groove and the rotating part cooperate, and the shape of the square groove itself is used to limit the rotating part. When the baffle is needed to block it, it is only necessary to continuously flip the baffle up through external force until the rotating part flips over the side wall of the square groove. Then, the side wall of the square groove will limit the baffle from flipping down spontaneously under the action of gravity.

[0012] Optionally, the ends of the pull-out plate on both sides opposite to each other are connected with ball bearings, and a ball groove for inserting the ball bearings is provided at one end of the inner side of the mounting frame away from the cabinet door.

[0013] By adopting the above technical solution, when the pull-out plate slides, the ball head will be retracted into the pull-out plate; when the pull-out plate completely slides into the transverse guide rail, the ball head will pop out and be embedded in the ball groove to achieve preliminary positioning of the pull-out plate and improve the stability of the pull-out plate.

[0014] Optionally, a support plate for supporting the mounting frame is protruded from the bottom of the inner side of the cabinet.

[0015] By adopting the above technical solution, after placing the pull-out plate and multiple electrical components, the mounting frame is relatively heavy, and the setting of the support plate applies an upward supporting force to the mounting frame, reducing the probability of the mounting frame bending downward and deforming and getting stuck in the vertical guide rail.

[0016] Optionally, ventilation holes are provided on both sides of the mounting frame.

[0017] By adopting the above technical solution, a large amount of heat is easily generated when the electrical components are in operation, and the opening of the vents enhances the heat dissipation.

[0018] Optionally, a ventilation plate is provided on the side wall of the cabinet.

[0019] By adopting the above technical solution, the ventilation plate and the vents cooperate to strengthen the internal and external air convection and further enhance the heat dissipation.

[0020] Optionally, a heat dissipation space is formed between the mounting frame and the cabinet door.

[0021] By adopting the above technical solution, the setting of the heat dissipation space also strengthens air convection and enhances the heat dissipation effect.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The pull-out plate can be inserted into the sliding grooves of different layers according to actual needs to adjust the installation height of the pull-out plate to meet the assembly requirements of electrical components of different quantities and specifications. When installing electrical components, the mounting frame can be pulled out as a whole for easy operation; the pull-out plate cooperates with the pull-out mounting frame to improve the simplicity and practicality of the use of the low-voltage switch cabinet;

[0024] 2. The square groove and the rotating part cooperate, and the shape of the square groove itself is used to limit the rotating part. When the baffle is needed to block, it is only necessary to continuously flip the baffle upward by external force until the rotating part flips over the side wall of the square groove. Then, the side wall of the square groove will limit the baffle from spontaneously flipping down under the action of gravity;

[0025] 3. This application strengthens the air convection inside and outside the switch cabinet and enhances the heat dissipation effect by coordinating vents, ventilation plates and heat dissipation spaces. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a low-voltage switch cabinet with adjustable partition volume. Figure 1 The low-voltage switch cabinet with adjustable partition volume comprises a cabinet body 1 and a cabinet door 2 rotatably mounted on one side of the cabinet body 1 through a rotating shaft. Vertical guide rails 3 arranged opposite to each other are welded and mounted on both left and right sides of the upper and lower ends of the cabinet body 1, and a mounting frame 4 is slidably mounted between the upper and lower adjacent vertical guide rails 3, and the left and right sides of the mounting frame 4 are respectively slidably connected to the vertical guide rails 3 arranged on the left and right sides of the cabinet body 1. A plurality of pull-out plates 5 are detachably connected inside the mounting frame 4, and the pull-out plates 5 can be used to place different electrical components.

[0033] A support plate 11 is welded to the bottom of the inner side of the cabinet 1. The support frame 11 is arranged between the left and right adjacent vertical guide rails 3, and the side wall of the support frame 11 fits the side wall of the vertical guide rail 3. When the mounting frame 4 is installed inside the cabinet 1, the upper plate surface of the support plate 11 fits the lower plate surface of the mounting frame 4 to provide auxiliary support for the mounting frame 4, thereby preventing the mounting frame 4 from excessively deforming downward due to excessive load.

[0034] In order to enhance the ventilation and heat dissipation effect, multiple ventilation holes 41 are spaced apart from top to bottom on both sides of the mounting frame 4, and ventilation plates 12 are embedded and installed on both left and right sides of the cabinet 1. When the mounting frame 4 is inserted and fixed inside the cabinet 1, a heat dissipation space 13 is formed between the mounting frame 4 and the cabinet door 2. The ventilation holes 41, the ventilation plates 12 and the heat dissipation space 13 cooperate to enhance the air convection inside and outside the cabinet 1, improve the heat dissipation effect, and reduce the probability of failure of electrical components due to overheating.

[0035] Reference Figure 2 The mounting frame 4 is provided with a plurality of sliding grooves 42 for the pull-out plate 5 to be inserted and slidably arranged at intervals along the height direction, and the sliding grooves 42 are provided between the upper and lower adjacent vents 41 .

[0036] The mounting frame 4 is welded with a transverse guide rail 43 in the sliding groove 42, and the transverse guide rail 43 corresponds to the sliding groove 42 one by one. The two sides of the pull-out plate 5 are respectively inserted into the adjacent left and right transverse guide rails 43 arranged on the same layer, and can slide along the length direction of the transverse guide rail 43. A square groove 431 is formed at one end of the transverse guide rail 43 close to the cabinet door 2, and a baffle 44 for closing the transverse guide rail 43 is rotatably connected to the square groove 431.

[0037] The baffle 44 includes a rotating portion 441 and a blocking portion 442 integrally formed at the top and bottom. The rotating portion 441 is rotatably connected to the square groove 431 via a rotating shaft. The blocking portion 442 extends out of the square groove 431 and can close the outlet end of the transverse guide rail 43. The groove wall of the square groove 431 restricts the rotating portion 441 from turning down spontaneously.

[0038] Reference Figure 3 and Figure 4The rear ends of the left and right sides of the pull-out plate 5 are threadedly mounted with ball heads 51, and when squeezed, the ball heads 51 can be completely retracted into the pull-out plate 5. A ball groove 45 for inserting the ball heads 51 is provided at one end of the inner side of the mounting frame 4 away from the cabinet door 2.

[0039] The implementation principle of a partitioned volume adjustable low-voltage switch cabinet in the embodiment of the present application is as follows: before installing electrical components, the cabinet body 1 is first pulled out along the vertical guide rails 3, the positions of the electrical components are arranged, and the pull-out plates 5 are inserted into the horizontal guide rails 43 at different layers according to actual needs to adjust the installation height of the pull-out plates 5. After the electrical components are installed, the cabinet body 1 is pushed back and the cabinet door 2 is closed, and the overall installation of the low-voltage switch cabinet is completed.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
