Description

Technical Field

It can monitor, control and protect the power system to ensure the safe and stable operation of the power system. The switchgear of the grid-connected box is usually a circuit breaker. A circuit breaker is a switching device used to protect the circuit. It can automatically disconnect the circuit when a short circuit, overload or other fault occurs in the circuit to protect electrical equipment and personal safety.

[0003] After the traditional circuit breaker is installed in the grid-connected box, the wires are installed on the top of the circuit breaker and need to be bent and passed through the bottom of the grid-connected box. At the same time, in order to ensure that the wires passing through the grid-connected box will not be tangled, cable ties are usually used to fix the wires together. However, cable ties usually fix the wires too tightly, which not only takes time and effort to use tools such as knives to remove the cable ties, but the use of knives increases the risk of scratching the wires, which will cause damage to the surface of the wires, thus affecting the appearance and quality of the wires.

[0026] Example

[0027] like Figure 1-4 As shown, the utility model proposes a switch device for a grid-connected box, comprising a circuit breaker 1 and a plurality of linearly arranged wires 2 installed on the top of the circuit breaker 1, and also comprising: a wire clamping mechanism installed on the circuit breaker 1 for restraining the wires 2 passing through the bottom of the grid-connected box until they are not tight; a clamping mechanism arranged inside the wire clamping mechanism for fixing wires 2 of different thicknesses.

[0028] Furthermore, the wire clamping mechanism includes a rotating wire clamping box 4, and a pair of clamping blocks 5 for limiting the opening size of the clamping plate 48 are provided inside the rotating wire clamping box 4 next to the circular wire clamping groove 41. The outer wall of the circuit breaker 1 is fixedly connected to a support seat 3 for supporting the rotation of the rotating wire clamping box 4. The rotating wire clamping box 4 is provided with a plurality of circular wire clamping grooves 41 distributed in a circular array and used for clamping the power wire 2. The rotating wire clamping box 4 is provided with a plurality of wire threading openings 42 corresponding to and connected to the circular wire clamping grooves 41.

[0029] The clamping mechanism includes a plurality of support rods 43 fixedly connected to the circuit breaker 1 and distributed in a circumferential array and corresponding to the circular clamping groove 41. A pair of first rotating rods 44 and second rotating rods 45 opposite to each other are fixedly connected to the support rods 43. The upper and lower ends of the support rods 43 are sleeved with first springs 46 and second springs 47 for pulling the first rotating rods 44 and second rotating rods 45 back to their original positions. The first springs 46 and second springs 47 function to make the first rotating rods 44 and second rotating rods 45 automatically rotate together. The ends of the first rotating rods 44 and second rotating rods 45 away from the support rods 43 are fixedly connected with clamping plates 48 for clamping the wires 2. The opposite surfaces of the clamping plates 48 are provided with anti-skid pads 49 for tightly adhering to the wires 2. The anti-skid pads 49 are made of rubber pads and their function is to prevent the wires 2 clamped by the pair of clamping plates 48 from slipping out at will.

[0030] Secondly, one end of the first spring 46 and the second spring 47 is fixedly connected to the inner wall of the rotating wire box 4, the other end of the first spring 46 is fixedly connected to the first rotating rod 44, and the other end of the second spring 47 is fixedly connected to the second rotating rod 45.

[0031] Furthermore, the rotating wire box 4 is movably connected with a rotating shaft 6, and one end of the rotating shaft 6 close to the rotating block 61 is provided with a protrusion for preventing the rotating shaft 6 from rotating after being inserted into the rotating wire box 4. The function of the protrusion is that when the rotating wire box 4 is held, the rotating shaft 6 cannot rotate at this time, and then the spiral sleeve block 62 can be rotated, so that the spiral sleeve block 62 is against the support seat 3, and then the rotating wire box 4 cannot be rotated on the support seat 3 through the rotating shaft 6. One end of the rotating shaft 6 is movably passed through the rotating wire box 4 and the support seat 3 in turn, and then fixedly connected with the rotating block 61, and the other end of the rotating shaft 6 is spirally connected with the spiral sleeve block 62, and the interior of the spiral sleeve block 62 is provided with an anti-slip block 63 fixedly connected to the other end of the spiral sleeve block 62, and the anti-slip block 63 is used to prevent the spiral sleeve block 62 from slipping out of one end of the rotating shaft 6.

[0032] In this embodiment, when it is necessary to use the switchgear circuit breaker 1 of the grid-connected box, multiple wires 2 are bent toward the side of the circuit breaker 1 with the support seat 3, and then the wires 2 are clamped in sequence from left to right in the circular wire clamping groove 41 and the wire threading port 42 on the rotating wire clamping box 4. Then the clamping mechanism in the rotating wire clamping box 4 will be activated, firstly causing the wires 2 to stretch out a pair of anti-slip pads 49 and clamping plates 48, while the first rotating rod 44 is subjected to the elastic rebound force of the first spring 46, and the second rotating rod 45 is subjected to the elastic rebound force of the second spring 47, so that the clamping plates 48 on the clamping plates 48 on the first rotating rod 44 drive the corresponding anti-slip pads 49 to clamp the wires 2 clamped in the circular wire clamping groove 41. When it is necessary to remove the corresponding wires 2 on the rotating wire clamping box 4, it is only necessary to forcefully pull them out of the rotating wire clamping box 4 and pass them through the corresponding wire threading port 42, which is simple and easy to operate;

[0033] When it is necessary to fix the rotating wire box 4 at a designated position after rotation and prevent the wires 2 installed on the rotating wire box 4 from shaking randomly, it is only necessary to hold the rotating wire box 4 and then rotate the spiral sleeve block 62. Since the spiral sleeve block 62 is spirally connected to one end of the rotating shaft 6, the spiral sleeve block 62 will move along the rotating shaft 6 toward the support seat 3. Then, through the rotating block 61 at the other end of the rotating shaft 6 and the protrusion inserted into the rotating wire box 4, the end of the spiral sleeve block 62 close to the support seat 3 is tightly pressed against the support seat 3, thereby generating a large friction force between the spiral sleeve block 62 and the support seat 3, thereby limiting the shaking of the rotating wire box 4 on the support seat 3.

[0034] The preferred embodiments of the utility model of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
