Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, in particular to a distribution cabinet for preventing electrostatic interference. Background Technique

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the end - level equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are suitable for occasions where the load is relatively scattered and the number of circuits is small, while motor control centers are used for occasions where the load is concentrated and the number of circuits is large. In the installation of existing distribution cabinets, due to dry weather and other reasons, static electricity will be generated, which will affect the work of staff and pose a certain danger.

[0003] For example, in the patent application with the authorization publication number CN210926743U, the authorization publication date of July 3, 2020, and the name "A Distribution Cabinet for Preventing Electrostatic Interference", an ion blower is installed at the top of the inner side wall of the cabinet body. When the ion blower is powered on, it can blow out a large amount of positive and negative ion winds to neutralize the static electricity generated on the surface of the cabinet body, further improving the anti - electrostatic interference ability of the distribution cabinet;

[0004] However, the following problems exist in the actual use of the above - mentioned device. The ion blower directly blows the airflow with positive and negative charges downward. Due to the limitation of the distance of the ion airflow, the amount of positive and negative charges of the airflow reaching the lower part of the distribution cabinet is small, thus reducing the anti - static effect in the bottom area inside the distribution cabinet.

[0005] Therefore, we propose a distribution cabinet for preventing electrostatic interference to solve the problems raised above. Content of the Utility Model

[0006] 1. Technical problems to be solved by the utility model:

[0007] The purpose of the utility model is to provide a distribution cabinet for preventing electrostatic interference to solve the problems in the current market proposed in the above - mentioned background technique.

[0008] 2. Technical solution:

[0009] To achieve the above - mentioned purpose, the utility model provides the following technical solution: A distribution cabinet for preventing electrostatic interference, including a cabinet body. An ion blower is installed inside the lower end of the cabinet body through fasteners, and a first mounting plate and a second mounting plate are successively installed above the ion blower from bottom to top, and the first mounting plate and the second mounting plate are fixed inside the cabinet body;

[0010] A flow guide pipe is fixed to the lower end of the first mounting plate, and a flow-through component is installed between the flow guide pipe and the ion blower. The upper end of the flow guide pipe is installed with an air outlet pipe through a sealed bearing. A rotating rod is installed in the middle of the flow guide pipe through a sealed bearing. The lower end of the rotating rod is fixedly provided with blades at equal angles. A driving member is installed between the upper end of the rotating rod and the lower end of the air outlet pipe. The driving member is used to drive the air outlet pipe to rotate forward and backward.

[0011] Furthermore, the flow-through component includes a tee pipe installed in the middle of the flow guide pipe. The lower end of the tee pipe is fixed with a first pipe body. The outer side of the lower end of the first pipe body is threadedly sleeved with a second pipe body. The second pipe body is threadedly sleeved on the outer side of the upper end of the third pipe body. The lower end of the third pipe body is communicated with the air outlet of the ion blower.

[0012] Through the above technical solution, when the second pipe body retracts and is sleeved on the outer side of the first pipe body, the ion blower can be removed for maintenance.

[0013] Furthermore, two air outlet pipes are symmetrically distributed about the center of the first mounting plate on the left and right, and air outlet openings are evenly arranged at equal intervals on the side of the air outlet pipe.

[0014] Through the above technical solution, an even static elimination effect inside the cabinet is achieved.

[0015] Furthermore, the driving member includes a sector gear fixed to the upper end of the rotating rod. The sector gear is sleeved inside a frame body. The lower end of the frame body is slidably installed with a "T"-shaped guide rod in the front and back directions. The guide rod is fixed to the upper end of the first mounting plate. Tooth blocks are evenly installed on the inner walls of the left and right sides of the frame body. The tooth blocks and the sector gear form a meshing structure.

[0016] Through the above technical solution, when the rotating rod rotates, it can drive the sector gear to rotate, and then drive the frame body to move back and forth by using the tooth blocks and the guide rod.

[0017] Furthermore, a rack is fixed to the side of the frame body. The side of the rack is meshed with a gear ring. The gear ring is fixedly sleeved on the outer side of the lower end of the air outlet pipe.

[0018] Through the above technical solution, after the rack moves back and forth, it can drive the gear ring and the air outlet pipe to rotate forward and backward to achieve swinging.

[0019] 3. Beneficial effects:

[0020] Adopting the technical solution provided by the present utility model, compared with the prior art, the power distribution cabinet of the present utility model for preventing electrostatic interference drives the air outlet pipe to swing through the driving member, expands the action area, improves the static elimination effect, and is convenient for repairing the ion blower at the same time. The specific content is as follows:

[0021] Start the ion blower. The ion blower blows the airflow with positive and negative charges into the diversion pipe through the flow-through component. Then, the ion airflow blows into the cabinet interior through the air outlet opened on the side of the air outlet pipe, improving the anti-static effect inside the cabinet. When the ion airflow flows in the diversion pipe, the blade drives the rotating rod to rotate. After the rotating rod rotates, the sector gear fixedly installed at the upper end of the rotating rod meshes with the tooth block. The frame body realizes the forward and backward movement on the guide rod by means of the fitting action with the guide rod, and then drives the rack to move forward and backward. When the rack moves forward and backward, the meshing action between the rack and the gear ring drives the gear ring and the air outlet pipe to rotate forward and backward, realizing the swinging operation of the air outlet pipe, expanding the action area of the air outlet pipe, and further improving the anti-static effect;

[0022] When the ion blower needs to be repaired, rotate the second pipe body. By using the threaded connection between the second pipe body and the first pipe body and the third pipe body, the second pipe body retracts outside the first pipe body, and then the fasteners can be removed to remove the ion blower for maintenance and repair, extending the service life.

A flow guide pipe 5 is fixed at the lower end of the first mounting plate 3, and a flow-through component 6 is installed between the flow guide pipe 5 and the ion blower 2. The upper end of the flow guide pipe 5 is installed with an air outlet pipe 9 through a sealed bearing. A rotating rod 7 is installed in the middle of the flow guide pipe 5 through a sealed bearing. Blades 8 are fixed at equal angles at the lower end of the rotating rod 7. A driving member 10 is installed between the upper end of the rotating rod 7 and the lower end of the air outlet pipe 9. The driving member 10 is used to drive the air outlet pipe 9 to rotate forward and backward; The flow-through component 6 includes a three-way pipe 61 installed in the middle of the flow guide pipe 5. A first pipe body 62 is fixed at the lower end of the three-way pipe 61. A second pipe body 63 is sleeved on the outer side of the lower end of the first pipe body 62 in a threaded manner. The second pipe body 63 is threadedly sleeved on the outer side of the upper end of a third pipe body 64. The lower end of the third pipe body 64 is communicated with the air outlet of the ion blower 2;

[0033] Combined with Figures 1-2 As shown, when the ion blower 2 needs to be repaired, rotate the second pipe body 63. By using the threaded connection between the second pipe body 63 and the first pipe body 62 and the third pipe body 64, the second pipe body 63 is retracted outside the first pipe body 62. Then, the fasteners can be removed to remove the ion blower 2 for maintenance and repair, extending its service life;

[0034] There are two air outlet pipes 9 symmetrically distributed about the center of the first mounting plate 3 on the left and right, and air outlets are equally spaced on the side of the air outlet pipe 9; The driving member 10 includes a sector gear 101 fixed at the upper end of the rotating rod 7. The sector gear 101 is sleeved inside a frame body 102. A "T"-shaped guide rod 103 is slidably installed at the front and rear of the lower end of the frame body 102, and the guide rod 103 is fixed at the upper end of the first mounting plate 3.

[0035] Combined with Figure 1 and Figures 3-4As shown, after the ion blower 2 is started, the airflow with positive and negative charges generated by the ion blower 2 enters the diversion pipe 5 through the flow-through component 6, and then blows into the cabinet 1 through the air outlet opened on the side of the air outlet pipe 9, improving the anti-static effect inside the cabinet 1. When the ion airflow flows in the diversion pipe 5, the rotating rod 7 is driven to rotate by the blade 8. After the rotating rod 7 rotates, the sector gear 101 fixedly installed at the upper end of the rotating rod 7 meshes with the tooth block 104. The frame 102 realizes forward and backward movement on the guide rod 103 by means of the fitting action with the guide rod 103, thereby driving the rack 105 to move forward and backward. When the rack 105 moves forward and backward, the gear ring 106 and the air outlet pipe 9 are driven to rotate forward and backward by the meshing action between the rack 105 and the gear ring 106, realizing the swinging operation of the air outlet pipe 9, expanding the action area of the air outlet pipe 9, and further improving the anti-static effect.

[0036] Working principle: When using this power distribution cabinet for anti-static interference, as Figures 1-4 shown, start the ion blower 2.
