Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a safety type electric power protection device. Background Art

[0002] At present, power protection is an important measure to ensure the safe and stable operation of power systems and equipment. Protection devices play a vital role in power systems. Once abnormal current or short circuit conditions are detected in the circuit, they will quickly and accurately cut off the circuit, thereby preventing the fault from expanding and protecting other electrical components from damage. In this way, circuit breaker protection devices effectively reduce economic losses and maintenance costs caused by faults.

[0003] The prior art discloses a safety type power protection device and a protection method thereof with the authorization announcement number of CN115528656B. The patent discloses a safety type power protection device and a protection method thereof, including an electrical box and a control panel. The control panel is fixed on the inner wall of the electrical box and is provided with a slide groove. The first and second connection blocks are slidably installed in the slide groove, respectively connecting the internal device and the external power supply. In addition, an absorption block is provided, which is grounded through an electric wire and fixed on the inner wall of the slide groove near the second connection block. When a circuit fails, the patent can automatically disconnect the circuit, and realize the grounding processing after the circuit is disconnected by popping open the component, and guide and release the residual current in the power equipment, thereby preventing maintenance personnel from electric shock, improving maintenance safety, and protecting the safety of electrical components inside the electrical box.

[0004] However, the patent realizes circuit breaking protection by cutting off the two connecting blocks, and realizes grounding protection by the conductive end on the connecting block and the conductive sheet on the absorbing block, thereby ensuring its safety measures. However, when in use, the connection between the insulating block and the wedge hole relies on interference fit to fix the connecting block and the absorbing block. However, the interference fit is not ideal because it is only realized by the magnetic repulsion between the magnetic blocks. When the circuit repair work is completed, since the connecting block and the absorbing block are tightly connected by interference fit, it is difficult to separate them and use them again, which not only increases the cost of maintenance, but also reduces the work efficiency.

[0005] In addition, when performing maintenance work, due to the limited internal space of the distribution cabinet and possible line of sight obstruction, it is often difficult for workers to clearly determine whether the grounding is successful, which undoubtedly increases the risk of maintenance work and has poor practicality.

[0029] like Figure 1-Figure 6As shown, the present embodiment proposes a safety-type power protection device, including a cabinet 1, a cabinet door 2 is installed on one side of the cabinet 1, a shell 3 is fixedly connected to the inner wall of the cabinet 1 by bolts, a fixing seat 11 is fixedly connected to the inner wall of the shell 3 by bolts, a sliding seat 10 is slidably assembled inside the shell 3, two directional rods 7 are welded inside the shell 3, sliding blocks 6 are slidably assembled on the outer peripheral surface of the directional rod 7, one side of the two sliding blocks 6 is respectively welded to the two sides of the sliding seat 10, a connecting seat is installed on the inner wall of the shell 3, two electromagnets 4 are installed at the bottom of the connecting seat, two magnetic blocks 5 are installed on the sliding seat 10, two fixing grooves are provided on the fixing seat 11, a conductive end 9 and two fixing blocks 8 are respectively installed at the bottom of the sliding seat 10, a limiting hole is provided on the fixing block 8, a disc 18 is slidably assembled inside the fixing seat 11, a conductive sheet 19 is installed on the top of the disc 18, and sliding plates are slidably assembled inside the fixing seat 11 13 and two pushing rods 12, one end of the pushing rod 12 is fixedly connected to one side of the sliding seat 10, and two inclined sliding rods 14 are slidably equipped on the sliding plate 13, and one end of the inclined sliding rod 14 is welded with a connecting rod 15, and one end of the connecting rod 15 is fixedly connected to a clamping plate 16, and a limiting block 17 is installed on one side of the clamping plate 16. One side of the sliding plate 13 is fixedly connected to a cross bar. Through the arrangement of structures such as the fixed block 8 and the limiting block 17, when the sliding seat 10 moves downward, it will apply pressure to the pushing rod 12, and this pressure will push the sliding plate 13 to move. During the movement of the sliding plate 13, the movement of the clamping plate 16 is realized through the inclined sliding rod 14 to ensure that when the fixed block 8 is fully moved into the fixed groove, the limiting block 17 can be stuck in the limiting hole, thereby realizing close contact between the conductive end 9 and the conductive sheet 19, ensuring the reliability of grounding, thereby making the fixing operation more convenient and providing a safer working environment.

[0030] like Figure 3-Figure 5 As shown, an inclined sliding groove is provided on the sliding plate 13, and the bottom end of the inclined sliding rod 14 is slidably connected inside the inclined sliding groove.

[0031] like Figure 3-Figure 5 As shown, a circular groove is formed on the fixing seat 11, and a circular disc 18 is slidably connected inside the circular groove. A compression spring is fixedly connected between the circular disc 18 and the inner wall of the circular groove.

[0034] like Figure 1-Figure 3 As shown, a directional hole is formed on the sliding block 6, and the directional rod 7 passes through the interior of the directional hole.

[0035] The specific implementation principle of this embodiment is as follows: when a circuit fails, the electromagnet 4 is powered off and no longer attracts the magnetic block 5, the sliding seat 10 is no longer restricted and moves downward under the influence of gravity, and at the same time the sliding seat 10 and the connecting seat are no longer connected, so that the circuit is in an open circuit state, and the sliding block 6 drives the sliding seat 10 to move downward along the direction of the directional rod 7 through the restriction of the directional rod 7;

When the fixed block 8 moves to the inside of the fixed groove, the clamping plate 16 continues to move, through the limit block 1 The sliding of 7 makes the movement of the clamping plate 16 and the fixed block 8 not restricted. When the sliding seat 10 and the fixed seat 11 are fitted together, the limit spring drives the limit block 17 to be stuck into the limit hole to achieve fixation. At the same time, the conductive end 9 and the conductive sheet 19 are fitted together, and the grounding wire installed on the conductive sheet 19 is used for grounding to conduct the remaining current after the circuit is broken and the current in the circuit to prevent the maintenance personnel from getting an electric shock. After the maintenance is completed, the cross bar is driven, and the sliding plate 13 is driven to move up in the same way as the above steps to achieve the reset of the device.

A rotating shaft 22 is rotatably installed inside the cabinet 1, and a driving gear 23 is fixedly sleeved on the outer circumference of the rotating shaft 22. A warning plate 25 is welded to one end of the driven rack plate 24. Through the arrangement of the warning plate 25, the driving gear 23 and other structures, the driving gear 23 is meshed with the driven rack plate 24. When the driving gear 23 rotates, it drives the driven rack plate 24 to perform corresponding movements. When the sliding seat 10 is in full contact with the fixed seat 11, the driven rack plate 24 will drive the warning plate 25 to move, so that the staff can more clearly judge whether the grounding is successful.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
