Description

Technical Field

[0001] This utility model specifically relates to a safety-protected and sealed high and low voltage switchgear, belonging to the technical field of low voltage switchgear equipment. Background Technology

[0002] Low-voltage switchgear is a complete set of power distribution equipment used in power systems for AC or DC circuits with rated voltage. It is mainly used for receiving, distributing, controlling and protecting electrical energy. It is widely used in industrial plants, commercial buildings, municipal facilities and other fields. Its core function is to achieve centralized management of low-voltage circuits through modular design, so as to ensure the safety, efficiency and reliability of power transmission. In order to improve the sealing performance of low-voltage switchgear, a sealing layer is set. For example, a safety protection and sealing high and low voltage switchgear mentioned in authorization announcement number CN220358612U includes a low-voltage switchgear body, and a connecting block is rotatably connected inside the low-voltage switchgear body.

[0003] However, existing technologies still have the following problems:

[0004] In this device, the sealing performance of the low-voltage switchgear is improved by setting up limiting sleeves and sealing gaskets. However, when wires pass through the cabinet, it is difficult to easily insert and seal the conduit, resulting in poor sealing performance. Furthermore, while ensuring sealing performance, it is difficult to achieve ventilation and heat dissipation, which can easily damage the electrical equipment inside the low-voltage switchgear and is not conducive to its widespread use.

[0005] To address the aforementioned problems, the inventors have proposed a safety-protected, sealed high and low voltage switchgear to solve these issues. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a safe and sealed high and low voltage switchgear, which better solves the problems of difficulty in sealing wire holes and difficulty in ensuring ventilation and heat dissipation while maintaining a seal.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a safety protection and sealing high and low voltage switch cabinet, comprising a cabinet body, wherein conduits are fixedly connected through the bottom surface and rear surface of the cabinet body, and an insertion mechanism is provided in the inner cavity of the conduits. The insertion mechanism includes a first plug located inside the conduits, an insertion rod fixedly connected to one side of the first plug, and a second plug provided on one side of the first plug. Wire holes are opened on the opposite side surfaces of the second plug and the first plug. Ventilation pipes are fixedly connected through the two side surfaces of the cabinet body, and a rotary motor is provided in the inner cavity of the ventilation pipes. A fan blade is provided on one side of the rotary motor. A shielding mechanism is provided on the opposite side surfaces of the two ventilation pipes, and the shielding mechanism includes a shielding plate that is slidably and sealingly connected to the opposite side surfaces of the two ventilation pipes. A moving block is fixedly connected to the outer surface of the shielding plate, and a guide box is slidably connected to one side surface of the moving block. A lead screw is provided in the inner cavity of the guide box, and a servo motor is fixedly connected to the top of the guide box.

[0008] Preferably, in order to better improve the airtightness of the cabinet, a sealing door is movably connected to one side surface of the cabinet via a pivot, and a magnetic sealing layer is snapped and fixedly connected to the sealing door near the side surface of the cabinet.

[0009] Preferably, in order to better combine the first plug and the second plug, an insertion groove is provided on the surface of the second plug near the first plug, and the insertion groove matches the structural dimensions of the insertion rod.

[0010] Preferably, in order to better prevent air leakage at the wire hole, the first plug and the second plug are combined in a frustum-shaped structure, and both the outer surface of the first plug and the outer surface of the second plug are provided with anti-slip textured layers.

[0011] Preferably, in order to better support the rotary motor, a support rod is fixedly connected to the outer surface of the rotary motor, the end of the support rod away from the rotary motor is fixedly connected to the ventilation pipe, and the output end of the rotary motor is fixedly connected to the fan blade body.

[0012] Preferably, in order to better drive the rotation of the lead screw, one end of the lead screw is fixedly connected to the output end of the servo motor, and the end of the lead screw away from the servo motor is movably connected to the guide box through a bearing.

[0013] Preferably, in order to better ensure the movement of the combination of the insert block and the moving block, the moving block is fixedly connected to the side surface away from the baffle plate, one end of the insert block is threadedly connected to the outer surface of the lead screw body, and a groove matching the structural size of the insert block is opened on one side surface of the guide box.

[0014] Preferably, in order to better filter and block dust from the ventilation ducts, dust cover is threadedly connected to the outer surface of the two ventilation ducts facing away from each other, and a rotating rod is fixedly connected to the outer surface of the dust cover.

[0015] The beneficial effects of this utility model are:

[0016] By incorporating a conduit and insertion mechanism, air leakage can be effectively prevented when wires pass through the cabinet. Both the first and second plugs have holes on their opposite surfaces to allow wires to pass through. The first and second plugs are combined in a frustum shape, which better fits the inner wall of the conduit, enhancing sealing. Furthermore, the insertion rod and slot work together to ensure a tighter connection between the first and second plugs, improving the sealing effect and effectively preventing external dust and moisture from entering the cabinet, thus protecting the internal electrical equipment.

[0017] By incorporating ventilation ducts, a rotary motor, fan blades, and a shielding mechanism, the rotary motor drives the fan blades to rotate when heat dissipation is needed, enabling air circulation between the inside and outside of the cabinet. This effectively removes heat generated by the electrical equipment inside the cabinet, providing excellent heat dissipation and extending the equipment's lifespan. When heat dissipation is not required or the external environment is harsh, the servo motor drives the lead screw to rotate, causing the shielding plate to slide on the surface of the ventilation duct. This reduces or even closes the ventilation openings, satisfying both ventilation and heat dissipation needs while allowing for flexible adjustments based on actual conditions, preventing external debris from entering the cabinet.

[0024] 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.

[0025] Please see Figures 1-5 As shown, a safety-protected sealed high and low voltage switchgear includes a cabinet body 1. A sealing door 8 is movably connected to one side surface of the cabinet body 1 via a pivot. A magnetic sealing layer is snapped and fixedly connected to the sealing door 8 near the side surface of the cabinet body 1. A male buckle is fixedly connected to one side surface of the sealing door 8, and a female buckle is provided on one side of the cabinet body 1. The sealing door 8 is fixedly connected to the cabinet body 1 by combining the male and female buckles. The male and female buckles are common components and will not be described in detail here. The sealing door 8 is movably connected to the cabinet body 1 by magnetic sealing through the magnetic sealing layer to ensure sealing, which is a known technical means. A conduit 2 is fixedly connected through the bottom surface and the rear surface of the cabinet body 1. Wires pass through the conduit 2 and connect to the electrical components inside the cabinet body 1.

[0026] The inner cavity of the conduit 2 is provided with an insertion mechanism 3, which includes a first plug 31 located inside the conduit 2. An insertion rod 32 is fixedly connected to one side of the first plug 31, and a second plug 33 is provided on one side of the first plug 31. An insertion groove 35 is opened on the surface of the second plug 33 near the first plug 31. The insertion groove 35 matches the structural dimensions of the insertion rod 32. The insertion rod 32 is inserted into the insertion groove 35 to ensure the stability of the first plug 31 and the second plug 33 after combination. A wire hole 34 is opened on the opposite side surface of the second plug 33 and the first plug 31. The first plug 31 and the second plug 33 are combined into a frustum-shaped structure. An anti-slip texture layer is opened on the outer surface of the first plug 31 and the outer surface of the second plug 33. The first plug 31, the second plug 33 and the insertion rod 32 are all made of silicone and have a certain degree of elasticity. The frustum-shaped structure of the first plug 31 and the second plug 33 can better fit the inner wall of the conduit 2 and improve the sealing performance.

[0027] Ventilation pipes 4 are fixedly connected to both sides of the cabinet 1. Dust covers 10 are threadedly connected to the outer surfaces of the two ventilation pipes 4 facing away from each other. A rotating rod is fixedly connected to the outer surface of the dust cover 10, which can be rotated by the rotating rod. A dust filter hole is opened through one side of the dust cover 10. A rotary motor 5 is installed inside the ventilation pipe 4. A support rod 9 is fixedly connected to the outer surface of the rotary motor 5. The end of the support rod 9 away from the rotary motor 5 is fixedly connected to the ventilation pipe 4. The output end of the rotary motor 5 is fixedly connected to the fan blade body 6. The rotary motor 5 is fixedly connected to the ventilation pipe 4 through the support rod 9 to ensure the stability of the rotary motor 5. When the rotary motor 5 is started, it drives the fan blade body 6 to rotate, generating airflow. The fan blade body 6 is located on one side of the rotary motor 5.

[0028] Two ventilation ducts 4 are provided with shielding mechanisms 7 on opposite sides. The shielding mechanism 7 includes shielding plates 71 that are slidably and sealingly connected to the opposite sides of the two ventilation ducts 4. A moving block 72 is fixedly connected to the outer surface of the shielding plate 71. A fitting block 76 is fixedly connected to the side of the moving block 72 away from the shielding plate 71. One end of the fitting block 76 is threadedly connected to the outer surface of the lead screw body 74. A groove matching the structural dimensions of the fitting block 76 is provided on one side surface of the guide box 73. The guide box 73 is slidably connected to one side surface of the moving block 72. The lead screw body 74 is provided inside the guide box 73. One end of the lead screw body 74 is fixedly connected to the output end of the servo motor 75. The end of the lead screw 74 away from the servo motor 75 is movably connected to the guide box 73 via a bearing. The servo motor 75 drives the lead screw 74, which is fixedly connected at one end, to rotate. The end of the lead screw 74 away from the servo motor 75 is movably connected to the guide box 73 via a bearing to ensure stable rotation of the lead screw 74. The sleeve block 76 moves on the lead screw 74. Since a groove matching the structural size of the sleeve block 76 is opened on one side surface of the guide box 73, the sleeve block 76 moves along the groove, thereby driving the moving block 72 to move and causing the baffle plate 71 to slide, thereby reducing the ventilation opening or even closing the ventilation pipe 4. The servo motor 75 is fixedly connected to the top of the guide box 73.

[0029] It should be noted that: all electrical components in this case, such as rotary motor 5 and servo motor 75, should be connected to their compatible power supplies via wires by those skilled in the art. Furthermore, appropriate controllers, such as PLC controllers or microcontrollers, should be selected according to the actual situation to meet control requirements. Specific connections and control sequences should refer to the working principle described below, where the electrical connections are completed according to the sequential operation of each electrical component. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0030] Working principle: During use, the bottom surface and rear surface of the cabinet 1 are both fixedly connected with conduits 2. When it is necessary to insert the wire into the cabinet 1, the operator passes the wire through the wire hole 34 opened on the opposite side surface of the first plug 31 and the second plug 33, and inserts the insertion rod 32 fixedly connected to one side of the first plug 31 into the insertion groove 35 opened on the side surface of the second plug 33 near the first plug 31, so that the first plug 31 and the second plug 33 are tightly connected.

[0031] Furthermore, since the first plug 31 and the second plug 33 are combined to form a frustum-shaped structure, this shape can better fit the inner wall of the conduit 2, the wire is stably fixed in the conduit 2, and the wire is effectively prevented from leaking air when passing through the cabinet 1, preventing external dust, moisture and other substances from entering the cabinet 1 and protecting the internal electrical equipment.

[0032] Furthermore, when the electrical equipment inside the cabinet 1 generates heat and needs to be dissipated, the rotary motor 5 inside the ventilation pipe 4 starts to work. The rotary motor 5 is stably fixed inside the ventilation pipe 4 by the support rod 9 fixedly connected to the outer surface. Its output end is fixedly connected to the fan blade body 6. The rotary motor 5 drives the fan blade body 6 to rotate, realizing the circulation of air inside and outside the cabinet 1, effectively removing the heat generated by the electrical equipment inside the cabinet 1, playing a good heat dissipation role, extending the service life of the equipment, and the incoming air is filtered by the dust cover 10.

[0033] Furthermore, when sealing is required, the servo motor 75 fixedly connected to the top of the guide box 73 starts to work, driving the lead screw body 74 to rotate. The sleeve block 76 fixedly connected to the side surface of the moving block 72 away from the baffle plate 71 is threadedly connected to the outer surface of the lead screw body 74. As the lead screw body 74 rotates, the sleeve block 76 moves on the lead screw body 74. Since a groove matching the structural size of the sleeve block 76 is opened on one side surface of the guide box 73, the sleeve block 76 moves along the groove, thereby driving the moving block 72 to move.

[0034] Furthermore, the moving block 72 drives the shield 71, which is fixedly connected to it, to slide in a sealed fit on the opposite side surfaces of the two ventilation pipes 4. By controlling the forward and reverse rotation of the servo motor 75, the shield 71 can be driven to slide, thereby reducing the ventilation opening or even closing the ventilation pipe 4. This satisfies the ventilation and heat dissipation requirements and can be flexibly adjusted according to the actual situation to prevent external debris from entering the cabinet 1.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
