Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet protection, in particular to an explosion-proof power distribution cabinet with separation of strong and weak electricity. Background Art

[0002] The distribution cabinet is also known as the distribution box, which is the final equipment of the distribution system. The distribution box is a general term for the motor control center. The distribution box is suitable for occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in occasions where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The Chinese utility model patent with authorization announcement number CN214204560U discloses an explosion-proof distribution cabinet with separated strong and weak currents, which relates to the technical field of distribution cabinets. It aims to solve the problem that existing distribution cabinets have poor heat dissipation conditions and cannot dissipate heat in time. The existing distribution boxes lack shock-absorbing protection devices. When the distribution box shakes, it is very easy to affect the internal circuit, causing electrical short circuits. The cabinet comprises a housing, a heat sink, an isolation plate and a base. The housing has a square structure and is made of low-carbon alloy steel. The housing is connected to a sealed door via a hinge. A base is provided at the bottom of the housing, and the housing and the base are connected by a support shaft and a connecting rod. A support spring is provided on the support shaft, and the support spring is installed between the connecting rods. When the housing is vibrated by external forces, the support shaft on the base is pressed downward by force to produce contraction and deformation. The connecting rod on one side is squeezed to both sides and slides on the support rod, and the support spring is compressed to disperse the force, thereby protecting the electronic components inside the housing.

[0004] The above-mentioned existing technical solutions only rely on isolation plates to separate strong and weak electricity, and their isolation effect may be uncertain. As time goes by, the isolation plates may be affected by environmental factors such as temperature, humidity and dust, thereby reducing their isolation effect. Therefore, it is urgent to design an explosion-proof distribution cabinet that separates strong and weak electricity to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide an explosion-proof distribution cabinet with separation of strong and weak electricity, so as to solve the problem that the isolation effect of the above-mentioned background technology that only relies on isolation plates to separate strong and weak electricity may be uncertain. As time goes by, the isolation plates may be affected by environmental factors such as temperature, humidity and dust, thereby reducing their isolation effect.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an explosion-proof distribution cabinet with separation of strong and weak electricity, comprising: a cabinet body, the cabinet body comprising a weak current box and a strong current box, a protective component fixedly connected to the interior of the cabinet body, the protective component comprising a fixed frame, the interior of the fixed frame being fixedly connected to a control module, the inner surface of the fixed frame being fixedly connected to a servo motor, the output end of the servo motor being fixedly connected to a first rotating ring, the outer surface of the first rotating ring being movably connected to a belt, the inner surface of the belt being movably connected to a second rotating ring, the inner surface of the second rotating ring being fixedly connected to a threaded rod, the outer surface of the threaded rod being movably connected to a sliding block, the outer surface of the sliding block being fixedly connected to a plasma blower, a support groove being provided inside the fixed frame, the interior of the weak current box being movably connected to a partition, the outer surface of the partition being fixedly connected to a limiting block.

[0007] Preferably, the outer surface of the cabinet is movably connected with a heat dissipation component, and the heat dissipation component includes a limiting frame, and a fan is fixedly connected to the interior of the limiting frame.

[0008] Preferably, the outer surface of the limiting frame is movably connected to a clamping plate, and the lower surface of the clamping plate is fixedly connected to the limiting plate.

[0009] Preferably, a spring column is fixedly connected to the outer surface of the limiting plate, and a side of the spring column away from the limiting plate is fixedly connected to a support frame.

[0010] Preferably, the first rotating ring is sleeved on the inner side of one end of the belt, and the second rotating ring is sleeved on the inner side of the belt away from the first rotating ring.

[0011] Preferably, one end of the threaded rod is fixedly connected to the inside of the second rotating ring, and both ends of the threaded rod are movably connected to the inner wall of the supporting groove.

[0012] Preferably, the limit blocks are in two groups fixedly connected to both sides of the partition, and the limit blocks are movably connected to the inner walls of the weak current box and the strong current box.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Through the arrangement of the threaded rod and the plasma blower, under the action of the plasma blower, the plasma blower can generate a large number of positive and negative ions when working. These ions can neutralize the static electricity in the air inside the cabinet, eliminate static electricity in time, and reduce the interference of static electricity on strong and weak electrical equipment. Secondly, under the action of the threaded rod, the plasma blower can be adjusted in position so that the plasma blower can cover a larger area, ensuring that the static electricity in the entire cabinet can be effectively eliminated, thereby greatly reducing the possibility of fire caused by static electricity and improving the isolation effect.

[0015] The setting of fans and spring columns can speed up the flow of air around the distribution cabinet, quickly take away the heat, and reduce the temperature inside the cabinet. At the same time, when the fan fails or needs to be cleaned, it can be easily removed from the outer surface of the cabinet for repair or cleaning, which not only saves maintenance time but also reduces maintenance costs.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5, the utility model provides an embodiment: an explosion-proof distribution cabinet with separation of strong and weak electricity, comprising: a cabinet body 1, the cabinet body 1 includes a weak current box 11 and a strong current box 12, a protective component 2 is fixedly connected inside the cabinet body 1, the protective component 2 includes a fixing frame 21, the fixing frame 21 is fixedly connected to the inside of the control module 22, the inner surface of the fixing frame 21 is fixedly connected to a servo motor 23, the output end of the servo motor 23 is fixedly connected to a first rotating ring 24, the outer surface of the first rotating ring 24 is movably connected to a belt 25, the inner movably connected to the second rotating ring 26, the inner part of the second rotating ring 26 is fixedly connected to a threaded rod 27, the outer surface of the threaded rod 27 is movably connected to a sliding block 29, the outer surface of the sliding block 29 is fixedly connected to a plasma blower 210, a support groove 28 is opened inside the fixing frame 21, the inner part of the weak current box 11 is movably connected to a partition 211, and the outer surface of the partition 211 is fixedly connected to a limiting block 212.

[0024] Specifically, through the setting of the plasma blower 210, under the action of the plasma blower 210, the plasma wind blown out by the plasma blower 210 can cover the internal space of the cabinet 1, effectively neutralize the static electricity in the air, and prevent static electricity accumulation.

[0025] See also Figure 1-5 The outer surface of the cabinet 1 is movably connected to a heat dissipation component 3, and the heat dissipation component 3 includes a limiting frame 31, and a fan 32 is fixedly connected to the interior of the limiting frame 31.

[0026] Specifically, by setting up the fan 32, the wind blown out by the plasma blower 210 can be guided out, so as to avoid the wind blown out by the plasma blower 210 rotating and circulating inside the weak current box 11 and being unable to be effectively discharged, and at the same time, it can effectively play a role in heat dissipation.

[0027] See also Figure 1-5 The outer surface of the limiting frame 31 is movably connected to a clamping plate 33 , and the lower surface of the clamping plate 33 is fixedly connected to a limiting plate 34 .

[0028] Specifically, by setting the clamping plate 33, the heat dissipation component 3 can be limited to the outer surface of the cabinet 1 from the side of the cabinet 1, so that the heat dissipation component 3 can be quickly disassembled during subsequent maintenance and inspection.

[0029] See also Figure 1-5 A spring column 35 is fixedly connected to the outer surface of the limiting plate 34 , and a support frame 36 is fixedly connected to the side of the spring column 35 away from the limiting plate 34 .

[0030] Specifically, by setting the limiting plate 34, when the spring column 35 pushes the card plate 33 to limit, the limiting plate 34 can effectively prevent the card plate 33 from being disconnected from the support frame 36, thereby effectively improving the practicality of the device.

[0031] See also Figure 1-5 The first rotating ring 24 is sleeved on the inner side of one end of the belt 25 , and the second rotating ring 26 is sleeved on the inner side of the belt 25 away from the first rotating ring 24 .

[0032] Specifically, by setting the belt 25, when the servo motor 23 rotates, the threaded rod 27 can be effectively driven to rotate. At the same time, the servo motor 23 and the threaded rod 27 are placed vertically, which can effectively save internal space.

[0033] See also Figure 1-5 One end of the threaded rod 27 is fixedly connected to the inside of the second rotating ring 26 , and both ends of the threaded rod 27 are movably connected to the inner wall of the supporting groove 28 .

[0034] Specifically, through the setting of the threaded rod 27, when the plasma fan 210 is blowing air, the threaded rod 27 will pull the plasma fan 210 to move inside the fixed frame 21 through the sliding block 29, so that the wind blown by the plasma fan 210 can cover a larger range, thereby effectively improving the heat dissipation and static removal effect.

[0035] See also Figure 1-5 The limit blocks 212 are fixedly connected to both sides of the partition 211 in two groups, and the limit blocks 212 are movably connected to the inner walls of the weak current box 11 and the strong current box 12.

[0036] Specifically, through the setting of the partition 211, the surface of the partition 211 is hollowed out. On the one hand, the partition 211 can perform explosion-proof isolation, and on the other hand, it can effectively prevent parts or debris from falling from the inside of the weak current box 11 into the inside of the fixed frame 21, causing damage to the plasma blower 210.

[0037] Working principle: When in use, first insert the heat dissipation component 3 through the holes opened on the sides of the weak-current box 11 and the strong-current box 12. When the limit frame 31 contacts the side walls of the weak-current box 11 and the strong-current box 12, the card plate 33 will squeeze the spring column 35 inward. After the card plate 33 is pushed to the appropriate position, the card plate 33 will, under the action of the spring column 35, press the card plate 33 against the side openings of the weak-current box 11 and the strong-current box 12, thereby playing the role of limiting the heat dissipation component 3, and then start the fan 32, so that the fan 32 can circulate the hot air generated inside the weak-current box 11 and the strong-current box 12, thereby effectively promoting air circulation and cooling; the control module 22 monitors the weak current box 11 and the strong-current box 12 in real time When the positive and negative ions in the air inside the electric box 11 and the strong electric box 12 are unbalanced, the control module 22 starts the servo motor 23, so that the servo motor 23 drives the first rotating ring 24 to rotate. Since the first rotating ring 24 and the second rotating ring 26 are sleeved inside the belt 25, when the first rotating ring 24 rotates, it also drives the threaded rod 27 inside the second rotating ring 26 to rotate, so that the threaded rod 27 can drive the sliding block 29 to slide on its surface. When the plasma blower 210 is started, the plasma wind ejected by the plasma blower 210 can neutralize the ions inside the weak electric box 11 and the strong electric box 12, thereby effectively playing an explosion-proof role.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
