Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet protection, in particular to a box-type power distribution cabinet protection device. Background Art

[0002] Box-type distribution cabinets have a small footprint and are easy to install. They are often used in residential areas and construction sites. During use, in order to meet certain safety requirements, the distribution cabinet needs to have a grounding terminal inside and be grounded together with the cabinet body. The components installed inside the cabinet need to be connected to the grounding terminal like the cabinet body. Once the equipment leaks, the current flows into the ground through the ground wire, thereby avoiding electric shock accidents.

[0003] At present, when installing the box-type distribution cabinet after commissioning, the metal grounding plate is inserted into the ground for several meters through the interior of the box-type distribution cabinet until the terminal block on the top of the grounding plate is reserved inside the box-type distribution cabinet, and then the small head of the bolt is inserted into the through hole opened on one side of the terminal block, and then one end of the grounding wire is sleeved on the outside of the small head of the bolt through the connector, and then the bolt is installed on the small head of the bolt until the bolt squeezes the connector, and the grounding operation of the grounding wire is completed. Since the connector is always exposed to the air, when the box-type distribution cabinet is used for a long time in a relatively humid environment, the air The moisture in the air easily undergoes an oxidation reaction with the connector, causing corrosion of the connector, thereby increasing the grounding resistance. The increase in grounding resistance means that the grounding effect is reduced, and the fault current cannot be effectively conducted into the earth. Therefore, maintenance personnel are required to replace the grounding wire with a corroded connector. However, when replacing the grounding wire with a corroded connector, maintenance personnel are required to use tools to fix the big head end of the bolt and turn the nut at the same time until the bolt and the nut are separated. Only then can the connector and the bolt be separated and the grounding wire can be replaced, but this increases the time and effort required for replacing the grounding wire. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a box-type distribution cabinet protection device, which aims to improve the problem in the prior art that because the diameters of the pouring port and the pipeline on the mold are the same, when the metal solution enters the pouring port, it does not contact the side wall of the pouring port (only contacts the air), and its flow rate is relatively fast. After entering the pouring port, it will contact the side wall of the pouring port, and the side wall of the pipeline will be impacted due to the excessive flow rate. Under the above two conditions, the metal solution is prone to generate eddy currents in the pouring pipeline, causing more bubbles to be generated inside the metal solution.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solution: a box-type power distribution cabinet protection device, comprising:

[0006] The power distribution cabinet has a removable grounding plate installed in the inner cavity, and a terminal block for connecting the grounding wire is fixedly installed on the top of the grounding plate.

[0007] The through hole is provided on one side of the wiring board, and a mounting tube for connecting a ground wire is movably mounted in the inner cavity of the through hole.

[0008] The positioning cap has a positioning column fixedly installed at one end, and the outer wall of the positioning column is fixedly installed with multiple fixed springs distributed in a ring shape. The inner wall of the mounting tube is fixedly installed with a fixing ring for limiting the fixed springs, and one end of the mounting tube is fixedly installed with a limiting disk.

[0009] As a further description of the above technical solution:

[0010] The inner diameter of the positioning cap is larger than the outer diameter of the mounting tube.

[0011] As a further description of the above technical solution:

[0012] An installation slot that matches the grounding plate is provided at the bottom of the inner cavity of the power distribution cabinet. One end of the grounding plate away from the terminal block passes through the installation slot and extends to just below the power distribution cabinet.

[0013] As a further description of the above technical solution:

[0014] A plurality of plug-in posts are fixedly installed in a circular arrangement with the central axis of the through hole as the center on one side of the terminal block away from the positioning cap. A limit block is fixedly installed on one end of the plug-in post away from the terminal block. A through slot connected to the outer wall of the limit plate is opened on one side of the limit plate.

[0015] As a further description of the above technical solution:

[0016] An extrusion block for extruding the limit plate is fixedly installed on one side of the limit block close to the wiring board.

[0017] As a further description of the above technical solution:

[0018] The extrusion block is arranged obliquely at one end away from the limiting block, and the extrusion block is made of rubber material.

[0019] The utility model has the following beneficial effects:

[0020] In the present invention, when the connector is corroded, the positioning cap is pulled to move the positioning post away from the mounting tube until the positioning post is completely pulled out of the inner cavity of the mounting tube. This allows the positioning cap to be separated from the connector, and then the connector is separated from the outside of the mounting tube. This allows the grounding wire to be separated from the terminal block, effectively reducing the time and effort required for replacing the grounding wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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.

[0030] Reference Figure 1-6 The present invention provides an embodiment of a box-type power distribution cabinet protection device, comprising:

[0031] The distribution cabinet 1 has a grounding plate 2 removably installed in its inner cavity. A mounting groove compatible with the grounding plate 2 is provided at the bottom of the inner cavity of the distribution cabinet 1. The end of the grounding plate 2 away from the terminal block 3 passes through the mounting groove and extends to the bottom of the distribution cabinet 1. The top of the grounding plate 2 is fixedly installed with a terminal block 3 for connecting the grounding wire. After the distribution cabinet 1 is transferred to the designated position, the distribution cabinet 1 is first fixed, and then one end of the grounding plate 2 is inserted into the ground for several meters through the mounting groove until the top of the terminal block 3 is flush with the bottom of the inner cavity of the distribution cabinet 1. At this time, the grounding plate 2 is located inside the distribution cabinet 1.

[0032] A through hole is opened on one side of the terminal block 3, and a mounting tube 9 for connecting the grounding wire is movably installed in the inner cavity of the through hole. When the grounding plate 2 is inserted into the ground, one end of the mounting tube 9 is inserted from one end of the through hole to the other end of the through hole, and then the connector at one end of the grounding wire is sleeved on the outside of the mounting tube 9.

[0033] A plurality of through holes are provided on one side of the terminal block 3 , through which a plurality of mounting tubes 9 can be inserted, which is conducive to connecting a plurality of grounding wires to the terminal block 3 .

[0034] The positioning cap 5 has a positioning column 6 fixedly installed at one end, and the outer wall of the positioning column 6 is distributed in a ring and fixed with multiple fixed springs 4. The fixed springs 4 are composed of metal elastic parts, and the outer wall of the fixed springs 4 is curved, which can improve the plastic deformation ability of the fixed springs 4 and extend the service life of the fixed springs 4.

[0035] When the locking nut 5 is unlocked, the locking nut 5 is unlocked, and the locking nut 5 is unlocked, so that the locking nut 5 is unlocked and the locking nut 5 is unlocked.

[0036] When the connector is corroded, pull the positioning cap 5 to move the positioning column 6 away from the mounting tube 9 until the positioning column 6 is completely pulled out of the inner cavity of the mounting tube 9. This allows the positioning cap 5 to be separated from the connector, and then the connector is separated from the outside of the mounting tube 9. This allows the grounding wire to be separated from the terminal block 3, effectively reducing the time and effort required to replace the grounding wire.

[0037] The inner diameter of the positioning cap 5 is larger than the outer diameter of the mounting tube 9, so that one end of the mounting tube 9 can be inserted into the inner cavity of the positioning cap 5, which is conducive to one end of the positioning cap 5 being able to fit with one end of the connector and push the connector to move.

[0038] On one side of the terminal block 3 away from the positioning cap 5, a plurality of plug-in posts 12 are fixedly installed in a ring-shaped distribution with the central axis of the through hole as the center. A limit block 10 is fixedly installed on one end of the plug-in post 12 away from the terminal block 3. A through slot 8 is provided on one side of the limit plate 7 and is interconnected with its own outer wall. The through slot 8 is set to an L-shaped structure. When one end of the mounting tube 9 is inserted into the through hole and extends to the other side of the terminal block 3, the limit block 10 passes through the through slot 8 until one end of the limit plate 7 is fitted with the outer wall of the terminal block 3. At this time, the limit plate 7 is located between the terminal block 3 and the limit block 10. Then, the limit plate 7 is rotated until the outer wall of the plug-in post 12 is fitted with the inner wall of the through slot 8. At this time, the limit block 10 blocks one end of the limit plate 7 to prevent the mounting tube 9 from falling off from the through hole when the plug-in post 12 is inserted into the mounting tube 9.

[0039] A squeezing block 11 for squeezing the limit plate 7 is fixedly installed on one side of the limit block 10 close to the terminal board 3. When the limit plate 7 rotates, one end of the squeezing block 11 is in contact with one end of the limit plate 7 and continuously squeezes the limit plate 7, thereby improving the tightness of the contact between one end of the limit plate 7 and the outer wall of the terminal board 3.

[0040] The extrusion block 11 is tilted away from one end of the limit block 10. When the limit plate 7 rotates, the inclined side wall of the extrusion block 11 fits against one end of the limit plate 7, reducing the contact area between one end of the limit plate 7 and the extrusion block 11 and the resistance when the limit plate 7 rotates, thereby improving the smoothness of the rotation of the limit plate 7.

[0041] The extrusion block 11 is made of rubber material, which can improve the plastic deformation ability of the extrusion block 11. When the inclined end of the extrusion block 11 is in contact with the outer wall of the limit plate 7, the extrusion block 11 is deformed and continuously applies pressure to one end of the limit plate 7, further increasing the tightness of the contact between one end of the limit plate 7 and the outer wall of the terminal block 3.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
