Description

Technical Field

[0001] The utility model relates to the field of control cabinets, and more specifically, to a control cabinet that prevents accidental detachment. Background Art

[0002] A control cabinet assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment.

[0003] During operation, the control cabinet can be installed on a vertical pole using a hoop mechanism. When the locking bolts between the hoops become loose, the hoops are likely to become loose from the pole, resulting in a risk of the control cabinet falling off. If not discovered in time, serious consequences will occur. Therefore, it is necessary to design a control cabinet that prevents accidental detachment to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a control cabinet that prevents accidental detachment. An electromagnetic induction block and a magnetic attraction block are added between the positions of two side earpieces. When the locking bolts become loose, the electromagnetic induction block and the magnetic attraction block will first separate, and the electromagnetic induction block can send out a danger maintenance signal to remind the staff to come and supplement the locking force.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A control cabinet that prevents accidental detachment includes a control cabinet body installed outside a utility pole. Two pairs of arc-shaped hoop rings are symmetrically installed on the upper and lower sides of the outer end of the utility pole. The left and right ends of the arc-shaped hoop rings are symmetrically and fixedly connected with side earpieces. A extending rod is fixedly connected to the rear side of the front side earpiece, and an inner groove is opened on the front side of the rear side earpiece. A sponge base is fixedly connected to the rear inner wall of the inner groove, and a magnetic attraction block is fixedly connected to the front end of the sponge base. An electromagnetic induction block is fixedly connected to the end of the extending rod close to the magnetic attraction block.

[0009] Further, threaded holes are opened at the outer ends of the side earpieces, and a threaded nail is threadedly connected between two corresponding front and rear threaded holes.

[0010] Further, the front arc-shaped hoop ring is installed with the control cabinet body, and a locking bolt is threadedly connected to the outer end of the threaded nail.

[0011] Further, the electromagnetic induction block and the magnetic attraction block are magnetically connected.

[0012] Further, side slots are provided on the upper and lower inner walls of the inner groove, and micro electric rods are fixedly connected to the upper and lower ends of the extending rod.

[0013] Further, the output ends of the micro electric rods extend into the side slots, and the extending rod is located on the side of the locking bolt.

[0014] Further, an anti-slip inner strip is fixedly connected to the inner side wall of the arc-shaped clamping ring, and the anti-slip inner strip is in contact with the outer side wall of the electric pole.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] (1) In this solution, the control cabinet body is installed outside the electric pole through two arc-shaped clamping rings. At the same time, by using two locking bolts to lock the two arc-shaped clamping rings, the control cabinet body can be fixed at the position of the electric pole. When the two locking bolts are threadedly connected, an electromagnetic induction block and a magnetic attraction block can be arranged between the two side ear pieces. When the locking bolts become loose, the electromagnetic induction block and the magnetic attraction block are separated first, and the electromagnetic induction block can send out a dangerous maintenance signal to remind the staff to come and supplement the locking force.

[0018] (2) When the electromagnetic induction block and the magnetic attraction block are magnetically connected, the sponge base can provide a buffer space for the connection process of the magnetic attraction block and the electromagnetic induction block, so that the anti-slip inner strip can remain stable within the normal micro-movement range, avoiding false alarms, which is beneficial to ensuring the anti-detachment performance of the arc-shaped clamping ring outside the control cabinet body.

[0019] (3) At the same time, when the extending rod is inserted into the inner groove, the micro electric rods are inserted into the side slots, which not only ensures the docking stability of the electromagnetic induction block and the magnetic attraction block, but also provides the final limit when the two side ear pieces become loose, reducing the overall detachment risk of the arc-shaped clamping ring from the control cabinet body.
