Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet for electric power engineering which can prevent insect pests. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits, and the motor control center is used in occasions with concentrated loads and more circuits.

[0003] The current distribution cabinet will vibrate when in use, causing the distribution cabinet to shake to a certain extent, colliding with the ground to produce a certain amount of noise, affecting people's lives. In addition, the shock absorption form basically adopted by the distribution boxes on the market is relatively simple, and the structure is single, and the shock absorption effect is not ideal, which makes it impossible for the distribution cabinet to achieve the ideal shock absorption effect, resulting in poor stability of the distribution box during use and a greatly shortened service life.

[0004] In the prior art, a Chinese patent with publication number CN115764597A is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a shock absorbing device for a distribution cabinet, comprising a fixed base mechanism, a supporting mechanism is fixedly installed on the upper end of the fixed base mechanism, a pressure plate is fixedly installed on the upper end of the supporting mechanism, the fixed base mechanism comprises a base, and slide grooves are provided inside the four corners of the upper end of the base, a slider is clamped inside the slide groove, a rotating seat is fixedly installed on the upper end of the slider surface, and a tensile shock absorber is fixedly connected between the sliders. Since the distribution cabinet needs to be heat-dissipated, mosquitoes can easily enter the distribution cabinet from the heat dissipation holes and cause damage to electrical equipment. At present, a protective net is installed to prevent mosquitoes from entering. However, this method will cause the accumulation of mosquito corpses or dust, which will lead to poor heat dissipation effect of the equipment and reduce the service life. Utility Model Content

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An insect-proof power distribution cabinet for electric power engineering includes an equipment main body; the front end of the equipment main body is rotatably connected to a cabinet door, the bottom of the equipment main body is plugged with a dehumidification pad, both sides of the equipment main body are fixedly connected to fixed side panels, an insect attracting component, the insect attracting component is used to attract mosquitoes to approach, the insect attracting component is connected to the equipment main body, and the cleaning component is used to clean dust and mosquito corpses, and the cleaning component is connected to the equipment main body.

[0009] The above technical solution is adopted, in which the tail of the fixed side panel has a downward tilt angle. When it rains outdoors, rainwater can slide down along the angle of the fixed side panel, avoiding rainwater accumulation while keeping rainwater away from the heat sink and preventing rainwater from entering the main body of the device.

[0010] A further improvement of the technical solution of the utility model is that dust shields are inserted into the inner walls of the two heat sinks, four rectangular grooves are symmetrically opened on one side of the dust shield close to the heat sink, and arc plates are fixedly connected to the sides of the four rectangular grooves away from the heat sink.

[0012] A further improvement of the technical solution of the utility model is that an L-shaped plate is inserted into one side of the heat dissipation plate, an elastic protrusion block is fixedly connected to the top of the L-shaped plate, and a limited protrusion block is fixedly connected to one side of the L-shaped plate close to the rectangular groove.

[0013] The above technical solution is adopted, in which the L-shaped plate is an L-shaped structure, and a groove is provided on the top of the L-shaped plate, which is adapted to the shape contour of the groove set on the heat dissipation plate.

[0015] The above technical solution is adopted, in which the connection position between the M-shaped base and the limit base is an elastic structure. When the L-shaped plate is inserted, the above-mentioned arc plate is deformed first, and the arc plate is reset without being squeezed and fits with the elastic protrusion block to prevent the L-shaped plate from slipping.

[0017] By adopting the above technical solution, the spring in this solution has a certain pulling force and can play a certain limiting effect.

[0018] A further improvement of the technical solution of the utility model is that: one end of the spring is fixedly connected with a rack, the top of the rack is meshed with the outer wall of the half gear, and the bottom of the rack is plugged with a cleaning round stick.

When the L-shaped plate is inserted, the arc plate is first deformed, and the arc plate is reset without being squeezed, and fits with the elastic protrusion block to prevent the L-shaped plate from sliding off. Furthermore, the surfaces of the M-shaped base and the limit protrusion block are both smooth, and the elastic structures at the bottom of the two M-shaped bases are deformed toward the middle after being squeezed, so that the limit protrusion block can be completely inserted into the bottom of the rectangular groove, further strengthening the connection effect between the dust shield, the L-shaped plate and the heat sink, and the connection structure is simple, which saves time and effort when it needs to be disassembled for cleaning.

[0022] 2. The utility model provides a power distribution cabinet for electric power engineering that can prevent pests. The semi-gear is rotated by the action of the motor and pushes the rack to move on the surface of the fixed base. Since the number of teeth of the semi-gear is limited, the rack cannot continue to mesh with it after being pushed a certain distance, so that the rack is reset under the action of the spring, and the cleaning round stick can reciprocate to clean the surface of the heat sink, which can reduce the accumulation of dust and mosquito corpses on the surface of the heat sink and reduce the burden on the staff.

[0023] 3. The utility model provides a power distribution cabinet for electric power engineering that can prevent pests. The insect attracting component and the cleaning component cooperate with each other to attract mosquitoes to approach, thereby preventing mosquitoes from entering the equipment body through the heat sink and damaging internal components. The cleaning component can also clean the dust and mosquito corpses on the surface of the heat sink to ensure that the heat dissipation effect of the equipment is not affected.

[0033] The present invention is further described in detail below in conjunction with the embodiments:

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, the utility model provides an insect-proof power distribution cabinet for electric power engineering, including an equipment main body 1; the front end of the equipment main body 1 is rotatably connected to a cabinet door 2, the bottom of the equipment main body 1 is plugged with a dehumidification pad 3, both sides of the equipment main body 1 are fixedly connected to fixed side panels 4, an insect attracting component, the insect attracting component is used to attract mosquitoes to approach, the insect attracting component is connected to the equipment main body 1, and a cleaning component is used to clean dust and mosquito corpses, and the cleaning component is connected to the equipment main body 1.

[0036] In this embodiment, the dehumidification pad 3 can be inserted into the groove at the bottom of the device body 1 by plugging, so as to absorb moisture in the device body 1 to prevent the internal components of the device body 1 from being damaged and unusable due to excessive moisture.

[0037] Example 2

[0038] like Figure 4 and Figure 6As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the insect attracting component includes fixed side panels 4 fixedly connected to both sides of the device body 1, the bottoms of the two fixed side panels 4 are fixedly connected with insect attracting lamps 7, both sides of the device body 1 are plugged with heat sinks 5, the inner side walls of the two heat sinks 5 are plugged with dust shields 6, the dust shields 6 are symmetrically provided with four rectangular grooves 13 on one side close to the heat sink 5, and the four rectangular grooves 13 are fixedly connected with arc plates 14 on the side away from the heat sink 5.

[0039] In this embodiment, the tail of the fixed side panel 4 has a downward tilt. When it rains outdoors, rainwater can slide down along the angle of the fixed side panel 4, avoiding the accumulation of rainwater while keeping the rainwater away from the heat sink 5, thus preventing rainwater from entering the device body 1. Specifically, the connection between the arc plate 14 and the rectangular groove 13 is an elastic structure, which can be deformed upward or downward when encountering resistance.

[0040] Example 3

[0041] like Figure 5 , Figure 6 and Figure 7 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, an L-shaped plate 15 is inserted on one side of the heat dissipation plate 5, and an elastic protrusion block 16 is fixedly connected to the top of the L-shaped plate 15, and a limiting protrusion block 19 is fixedly connected to one side of the L-shaped plate 15 close to the rectangular groove 13, and a limiting base 17 is fixedly connected to one side of the rectangular groove 13, and M-shaped bases 18 are symmetrically installed on both sides of the limiting base 17, and the M-shaped base 18 and the limiting base 17 are an integrated structure.

[0042] In this embodiment, the L-shaped plate 15 is an L-shaped structure with a groove on its top, which is adapted to the shape of the groove set on the heat sink 5, and the side of the L-shaped plate 15 away from the limiting protrusion block 19 is bent inward, further strengthening the fixing effect of the L-shaped plate 15 on the heat sink 5.

[0043] Specifically, since the limiting base 17 and the M-shaped base 18 are an integrated structure, and the connection position between the M-shaped base 18 and the limiting base 17 is an elastic structure, when the L-shaped plate 15 is inserted, the above-mentioned arc plate 14 is deformed first, and the arc plate 14 is reset without being squeezed, and fits with the elastic protrusion block 16 to prevent the L-shaped plate 15 from slipping. Furthermore, the surfaces of both the M-shaped base 18 and the limiting protrusion block 19 are smooth, and the elastic structures at the bottom of the two M-shaped bases 18 are deformed toward the middle after being squeezed, so that the limiting protrusion block 19 can be completely inserted into the bottom of the rectangular groove 13, further strengthening the connection effect between the dust shield 6, the L-shaped plate 15 and the heat sink 5, and the connection structure is simple, which saves time and effort when disassembly and cleaning are required.

[0044] Example 4

[0045] like Figure 2 and Figure 3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the cleaning component includes a fixed base 8 fixedly connected to both sides of the device body 1, and springs 9 are fixedly connected to the inner walls of the two fixed bases 8, one end of the spring 9 is fixedly connected to a rack 11, the top of the rack 11 is meshed with the outer wall of the half gear 12, and a cleaning round stick 10 is inserted at the bottom of the rack 11.

[0046] In this embodiment, the half gear 12 rotates under the action of the motor and pushes the rack 11 to move on the surface of the fixed base 8. Since the number of teeth of the half gear 12 is limited, it cannot continue to engage with the rack 11 after pushing it a certain distance, so that the rack 11 is reset under the action of the spring 9, and the cleaning round roller 10 reciprocates to clean the surface of the above-mentioned heat sink 5.

[0047] The following is a detailed description of the working principle of the pest-proof power distribution cabinet for power engineering.

[0048] like Figure 1-7As shown, the L-shaped plate 15 and the device body 1 are an integrated structure. When in use, the groove on the surface of the heat sink 5 is first aligned with the groove on the top of the L-shaped plate 15. Since the side of the L-shaped plate 15 away from the limiting protrusion 19 has an inward bending arc, the heat sink 5 can be fixed to the outside of the device body 1 through the L-shaped plate 15. At the same time, the top of the other side of the L-shaped plate 15 has a rounded corner, which is adapted to the shape and contour of the arc-shaped plate 14. The connection position between the M-shaped base 18 and the limiting base 17 is an elastic structure. When the L-shaped plate 15 is inserted, the arc-shaped plate 14 is first deformed, and the arc-shaped plate 14 is reset without being squeezed, and fits with the elastic protrusion 16 to prevent the L-shaped plate 15 from slipping. Furthermore, the surfaces of both the M-shaped base 18 and the limiting protrusion 19 are smooth. After being squeezed, the elastic structures at the bottom of the two M-shaped bases 18 are deformed toward the middle, so that the limiting protrusion 19 can be completely inserted into the bottom of the rectangular groove 13, further strengthening The connection effect between the dust shield plate 6, the L-shaped plate 15 and the heat sink 5 is improved, and the connection structure is simple, which is more time-saving and labor-saving when it needs to be disassembled for cleaning. At the same time, the tail of the fixed side plate 4 has a downward tilt angle. When it rains outdoors, rainwater can slide down with the angle of the fixed side plate 4, avoiding rainwater accumulation while keeping rainwater away from the heat sink 5 and preventing rainwater from entering the device body 1. The insect attracting lamp 7 at the bottom of the fixed side plate 4 has the effect of luring mosquitoes to approach, reducing the phenomenon of mosquitoes entering the device body 1 from the heat sink 5. The half gear 12 rotates under the action of the motor and pushes the rack 11 to move on the surface of the fixed base 8. Since the number of teeth of the half gear 12 is limited, it cannot continue to mesh with the rack 11 after pushing it a distance, so that the rack 11 is reset under the action of the spring 9, and the cleaning round stick 10 is reciprocated to clean the surface of the heat sink 5, which can reduce the accumulation of dust and mosquito corpses on the surface of the heat sink 5 and reduce the burden on the staff.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
