DETAILED DESCRIPTION

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an electric power equipment protection device provided by an embodiment of the utility model includes a protection box 1 and a protection door 2. A support mechanism 7 is provided in the protection box 1, and a buffer mechanism 8 is fixedly installed on the support mechanism 7. The buffer mechanism 8 is located on both sides of the support mechanism 7. A transformer 6 is provided on the support mechanism 7, and a plurality of anti-slip structures 5 are fixedly installed on the upper surface of the protection box 1.

[0025] Furthermore, the protection door 2 is hingedly connected to the protection box 1 , a handle 3 is fixedly mounted on the protection door 2 , an observation window 4 is provided on the protection door 2 , and heat dissipation holes 101 are provided on both sides and the rear side of the protection box 1 .

[0026] Furthermore, a plurality of mounting holes are provided on the upper surface of the protection box 1, and each anti-slipping structure 5 is fixedly installed on each mounting hole respectively. Each anti-slipping structure 5 includes a cone beam coil 501, the lower end of the cone beam coil 501 is fixedly connected to the mounting hole, the upper end of the cone beam coil 501 is located on the protection box 1, and a locking nut 502 is threadedly connected to the cone beam coil 501.

[0027] In the present application, firstly, the locking nut 502 is rotated to disengage the rotating locking nut 502 from the cone beam coil 501, and then connected to the transformer 6 through a wire, and then the wire is passed through the cone beam coil 501 and the locking nut 502 and the end thereof is led out of the protective box 1, so that the end of the wire is connected to the electrical device, and the locking nut 502 is rotated in the reverse direction at will to make the locking nut 502 and the cone beam coil 501 threadedly connected until the cone beam coil 501 clamps the wire, wherein the inner wall of the cone beam coil 501 is made of rubber material to avoid damage to the wire when clamping the wire.

[0028] Furthermore, the supporting mechanism 7 includes two limit frames 701, which are respectively fixedly mounted on both sides of the inner bottom wall of the protective box 1, and each limit frame 701 is slidably connected with a limit bar 704. The upper surfaces of the two limit bars 704 are commonly fixedly connected with a bearing plate 702, and the transformer 6 is fixedly mounted on the bearing plate 702. A pull block 703 is fixedly connected to the front side of the bearing plate 702, and the pull block 703 abuts against the inner side of the protective door 2. Inverted U-shaped frames 705 are fixedly connected to both sides of the upper surface of the bearing plate 702.

[0029] In the present application, when the protective door 2 is closed, the pull block 703 abuts against the inner side of the protective door 2, effectively preventing the transformer 6 from shaking during operation and causing the limit bar 704 to slide back and forth in the limit frame 701, thereby improving the stability of the transformer 6. Through the setting of the limit frame 701 and the limit bar 704, it is convenient to pull the transformer 6 out of the protective box 1, thereby facilitating its inspection and maintenance, thereby improving the protection efficiency of the transformer 6.

[0030] Furthermore, the buffer mechanism 8 includes four connecting frames 801, each two connecting frames 801 form a group, each group of connecting frames 801 is respectively fixedly installed on the inner side of each inverted U-shaped frame 705, and two dampers 802 are fixedly installed in each connecting frame 801. The front ends of the two dampers 802 are commonly fixedly connected to a rubber plate 804, and a spring 803 is fixedly sleeved on the outside of each damper 802.

[0031] In the present application, because the transformer 6 will vibrate during operation, if this vibration is not reduced, in the long run, not only will the stability of the connection between the transformer 6 and the bearing plate 702 be reduced, but also the internal parts of the transformer 6 will become loose, thereby reducing its service life; when the transformer 6 vibrates due to operation, the rubber plates 804 on both sides will be squeezed, and with the help of the coordinated cooperation of the spring 803 and the damper 802, the shaking amplitude of the transformer 6 can be weakened, thereby playing a buffering role.

[0032] The working principle of this utility model:

[0033] When in use, firstly rotate the locking nut 502 to separate the rotating locking nut 502 from the cone beam coil 501, then connect it to the transformer 6 through the wire, then pass the wire through the cone beam coil 501 and the locking nut 502 and lead the end of the wire out of the protection box 1, so that the end of the wire is connected to the electrical device, and rotate the locking nut 502 in the opposite direction at will to make the locking nut 502 and the cone beam coil 501 threadedly connected until the cone beam coil 501 clamps the wire;

[0034] When the transformer 6 vibrates due to operation, the rubber plates 804 on both sides are squeezed. With the cooperation of the spring 803 and the damper 802, the shaking amplitude of the transformer 6 can be weakened, thereby playing a buffering role.

[0035] When the transformer 6 needs to be inspected, the protection door 2 is opened, and then the transformer 6 fixed on the bearing plate 702 is pulled out of the protection box 1 through the pull block 703, and the transformer 6 can be maintained.

[0036] In summary: this kind of power equipment protection device, through the threaded cooperation of the conical beam coil 501 and the locking nut 502, has the effect of clamping and fixing the wire, ensuring the reliability and stability of the connection between the wire and the transformer 6, and preventing the wire from falling off from the transformer 6 due to accidental touching the wire; the setting of the buffer mechanism 8 can have a buffering effect on the transformer 6 in a working state, avoiding the transformer 6 from vibrating during operation and reducing the stability of its connection with the supporting plate 702, and also avoiding the situation where the parts of the transformer 6 are loosened due to vibration, thereby improving its service life.
