Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically a switch cabinet for electrical engineering and automation. Background Technology

[0002] Switchgear is a type of electrical equipment mainly used for control and protection in power systems. Its main function is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes. It can be used in electrical engineering and automation fields.

[0003] During the use of switchgear, the electrical components to be installed need to be placed on the mounting rack inside the cabinet. However, when the existing switchgear is being maintained, workers have to reach into the cabinet to operate. Due to the limited space inside the cabinet, the range of movement is small, which can easily cause workers to be hindered during operation, resulting in time and effort wasted and affecting maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a switch cabinet for electrical engineering and automation, in order to solve the problem mentioned in the background art that when workers need to operate the switch cabinet during maintenance, the space limitation of the cabinet restricts their range of movement, which can easily cause obstruction of the worker's work, resulting in time and effort wasted and affecting maintenance efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch cabinet for electrical engineering and automation, comprising:

[0006] The main body includes a cabinet, the outer surface of which is fitted with a cabinet door, the inner surface of which is fitted with a mounting bracket, the surface of which is fixedly connected with electrical components, and the surface of which is provided with heat dissipation holes.

[0007] The moving mechanism includes a fixed rod, which is fixedly connected to the inner surface of the cabinet. The surface of the fixed rod has a sliding groove and a through hole. The surface of the mounting bracket is fixedly connected to a sliding rod. The surface of the fixed rod is fixedly connected to a mounting compartment. The inner surface of the mounting compartment is movably connected to a support spring and a partition. The surface of the partition is fixedly connected to an insert block. The surface of the sliding rod has an insertion hole.

[0008] Preferably, the length of the slide groove is the same as the length of the fixed rod, the slide rod is slidably connected to the surface of the slide groove, the cross-section of the slide rod and the slide groove is "T" shaped, and two sets of mounting chambers and through holes are provided, with the two sets of mounting chambers and through holes located on both sides of the fixed rod.

[0009] Preferably, one end of the support spring is fixedly connected to the inner surface of the installation chamber, the other end of the support spring is fixedly connected to the surface of the partition, the partition is abutted against the inner surface of the installation chamber, and the insert block is inserted into the surfaces of the through hole and the insertion hole.

[0010] Preferably, the diameter of the through hole is the same as the diameter of the insertion hole. There are two sets of insertion holes, which are located at both ends of the slide rod. Each set of insertion holes contains two holes, and each set of insertion holes is located on both sides of the slide rod.

[0011] Preferably, the inner surface of the cabinet is provided with a dustproof mechanism, which includes a dustproof mesh plate. The dustproof mesh plate is installed on the surface of the heat dissipation holes. A side rod and a threaded block are fixedly connected to the inner surface of the cabinet. A slot is opened on the surface of the dustproof mesh plate. A nut is abutted to the surface of the dustproof mesh plate. An installation rod is fixedly connected to the surface of the nut.

[0012] Preferably, the dustproof mesh is inserted and connected to the inner surface of the side rod, and two sets of side rods are provided. The two sets of side rods are installed on both sides of the dustproof mesh, and the cross-section of the side rod is "L" shaped.

[0013] Preferably, the threaded block is engaged with the surface of the slot, one end of the threaded block is fixedly connected to the inner surface of the cabinet, and the other end of the threaded block is threadedly connected to the inner surface of the nut. Two sets of mounting rods are provided, and the two sets of mounting rods are installed on both sides of the nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By separating the mounting bracket from the cabinet, the mounting bracket is not directly fixed to the inner surface of the cabinet. This allows the mounting bracket to be moved out of the cabinet along the direction of the sliding rod, thus enabling the electrical components to be moved out of the switch cabinet for maintenance. This avoids the situation where maintenance is carried out directly inside the cabinet, which would obstruct the operating space and reduce efficiency. At the same time, under the action of the support spring, the plug and through hole / socket can be connected, thereby limiting the position of the mounting bracket and sliding rod before and after movement.

[0016] 2. By installing and covering the surface where the heat dissipation holes are located, the dustproof mesh can play a role in dust protection, so as to prevent dust from the outside of the switch cabinet from entering the cabinet through the heat dissipation holes and adhering to the electrical components. This reduces the difficulty of cleaning and prevents the electrical components from being damaged due to long-term dust accumulation. At the same time, the installed dustproof mesh can be limited and fixed by the connection of threaded blocks, slots, and nuts. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A switch cabinet for electrical engineering and automation includes:

[0026] The main body includes a cabinet 1, with a cabinet door 11 installed on the outer surface of the cabinet 1 and a mounting bracket 12 installed on the inner surface of the cabinet 1. Electrical components 13 are fixedly connected to the surface of the mounting bracket 12. Heat dissipation holes 14 are provided on the surface of the cabinet 1. The mounting bracket 12 is a support for installing electrical components 13 inside the switch cabinet. When in use, the electrical components 13 are fixed on its surface, and the heat generated by the electrical components 13 during use will be dissipated through the heat dissipation holes 14.

[0027] The moving mechanism includes a fixed rod 2, which is fixedly connected to the inner surface of the cabinet 1. The surface of the fixed rod 2 has a sliding groove 21 and a through hole 27. The surface of the mounting frame 12 is fixedly connected to a sliding rod 22. The surface of the fixed rod 2 is fixedly connected to a mounting compartment 23. The inner surface of the mounting compartment 23 is movably connected to a support spring 24 and a partition 25. The surface of the partition 25 is fixedly connected to an insert block 26. The surface of the sliding rod 22 has an insertion hole 28. There are two sets of fixed rods 2 installed on both sides of the inner surface of the cabinet 1. Each set of fixed rods 2 consists of two rods. The fixed rods 2 can be used to install and support the disassembled mounting frame 12.

[0028] Furthermore, the length of the slide groove 21 is the same as the length of the fixed rod 2. The slide rod 22 is slidably connected to the surface of the slide groove 21. The cross-section of the slide rod 22 and the slide groove 21 is "T" shaped. There are two sets of mounting chambers 23 and through holes 27. The two sets of mounting chambers 23 and through holes 27 are set on both sides of the fixed rod 2. With the connection of the slide rod 22 and the slide groove 21, the mounting frame 12 and the fixed rod 2 can be connected, thereby realizing the installation effect of the mounting frame 12. With the action of the mounting chamber 23, the support spring 24 and the partition plate 25 can be installed.

[0029] Furthermore, one end of the support spring 24 is fixedly connected to the inner surface of the mounting chamber 23, and the other end of the support spring 24 is fixedly connected to the surface of the partition 25. The partition 25 is abutted against the inner surface of the mounting chamber 23. The insert block 26 is inserted into the surfaces of the through hole 27 and the insertion hole 28. The support spring 24 can apply a supporting force to the surface of the partition 25 and make it and the insert block 26 always tend to move towards the through hole 27. Under the action of the partition 25, the insert block 26 can be limited to prevent it from moving out of the mounting chamber 23 under the action of the support spring 24. With the insertion of the insert block 26 and the through hole 27 and the insertion hole 28, the slide rod 22 can be limited to the surface of the slide groove 21. The side of the insert block 26 away from the partition 25 is hemispherical, which makes the insertion of the insert block 26 and the two sets of insertion holes 28 smoother when the slide rod 22 moves.

[0030] Furthermore, the diameter of the through hole 27 is the same as the diameter of the insertion hole 28. There are two sets of insertion holes 28, which are located at both ends of the slide rod 22. Each set of insertion holes 28 consists of two holes, and each set of insertion holes 28 is located on both sides of the slide rod 22. With the action of the through hole 27 and the insertion hole 28, the installation effect of the insertion block 26 can be achieved.

[0031] Furthermore, the inner surface of the cabinet 1 is provided with a dustproof mechanism, which includes a dustproof mesh plate 3. The dustproof mesh plate 3 is installed on the surface of the heat dissipation hole 14. A side rod 31 and a threaded block 32 are fixedly connected to the inner surface of the cabinet 1. A slot 33 is opened on the surface of the dustproof mesh plate 3. A nut 34 is abutted to the surface of the dustproof mesh plate 3. An installation rod 35 is fixedly connected to the surface of the nut 34. The size of the dustproof mesh plate 3 is larger than the size of the heat dissipation hole 14. Under the action of the dustproof mesh plate 3, the heat dissipation hole 14 can be covered to reduce the dust outside the switch cabinet from entering the interior through the heat dissipation hole 14.

[0032] Furthermore, the dustproof mesh 3 is inserted and connected to the inner surface of the side rod 31. There are two sets of side rods 31, which are installed on both sides of the dustproof mesh 3. The cross-section of the side rod 31 is "L" shaped. Under the action of the two sets of side rods 31, the dustproof mesh 3 can be limited and installed in a direction perpendicular to the side rod 31.

[0033] Furthermore, the threaded block 32 is engaged with the surface of the slot 33. One end of the threaded block 32 is fixedly connected to the inner surface of the cabinet 1, and the other end of the threaded block 32 is threadedly connected to the inner surface of the nut 34. Two sets of mounting rods 35 are provided, and the two sets of mounting rods 35 are installed on both sides of the nut 34. With the connection between the threaded block 32 and the slot 33, the dustproof mesh plate 3 can be supported. The connection between the nut 34 and the threaded block 32 can achieve the installation and fixation of the dustproof mesh plate 3. Under the action of the mounting rods 35, it is easier for the staff to rotate the nut 34, and the arc-shaped surface of the mounting rods 35 can improve the comfort during use.

[0034] Working principle: When the worker is inspecting the electrical components 13 inside the switch cabinet, the mounting bracket 12 is pulled to drive the slide rod 22 to slide on the surface of the slide groove 21. The plug 26 is then squeezed and moves into the mounting chamber 23 through the through hole 27, so that the partition 25 slides on the inner surface of the mounting chamber 23. The support spring 24 is compressed and the plug 26 is disconnected from the set of sockets 28. At this time, the worker can move the electrical components 13 out of the cabinet 1 by pulling the mounting bracket 12. When the through hole 27 and the hole of another set of sockets 28 are aligned, the plug 26 is inserted into it under the support force applied by the support spring 24, so as to complete the limiting and fixing of the removed mounting bracket 12 and move the electrical components 13 out of the cabinet 1 for inspection.

[0035] Before using the switch cabinet, the heat dissipation holes 14 should be dustproofed. First, attach the dustproof mesh plate 3 to the inner surface of the cabinet 1 and align it between the two sets of side rods 31. Then, slide the dustproof mesh plate 3 onto the cabinet 1 and insert it into the two sets of side rods 31. When the threaded block 32 and the slot 33 are engaged, align the inner side of the nut 34 with the threaded block 32 and rotate the mounting rod 35 so that the nut 34 is connected to the surface of the threaded block 32 by threads and presses against the dustproof mesh plate 3 when tightened, so as to complete the installation and fixation of the dustproof mesh plate 3 and achieve dustproofing of the heat dissipation holes 14.
