Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a high-voltage cabinet switch interlocking mechanism, comprising a high-voltage cabinet 1, a ventilation hole 2 is provided on one side surface of the high-voltage cabinet 1, a ventilation port 3 is provided inside the high-voltage cabinet 1, a foot support 4 is fixedly connected to the bottom of the high-voltage cabinet 1, a bracket 5 is fixedly connected to the inside of the high-voltage cabinet 1, a circuit breaker 6 is fixedly connected to the surface of the bracket 5, a cabinet door 7 is rotatably connected to the surface of the high-voltage cabinet 1, a interlocking mechanism 8 is provided on the inner wall surface of the high-voltage cabinet 1, and a splicing mechanism 9 is provided on the surface of the interlocking mechanism 8;

[0021] The interlocking mechanism 8 includes a limit groove 801, a limit block 802, a sliding plate 803, a clamping plate 804, a telescopic rod 805 and a cylinder 806. The inner wall surface of the high-voltage cabinet 1 is provided with a limit groove 801, the inner part of the limit groove 801 is connected to the limit block 802, the surface of the limit block 802 is fixedly connected to the sliding plate 803, the surface of the sliding plate 803 is connected to the clamping plate 804, the bottom of the sliding plate 803 is fixedly connected to the telescopic rod 805, and the other end of the telescopic rod 805 is fixedly connected to the cylinder 806. A positioning block 901 is fixedly connected to the surface of one side of the card plate 804. Through the setting of the interlocking mechanism 8, when the switch of the circuit breaker 6 needs to be interlocked, the cylinder 806 is first started. The operation of the cylinder 806 will drive the telescopic rod 805 to push the sliding plate 803 upward. At this time, the card plate 804 will drive the switch of the circuit breaker 6 during the upward movement. The three groups of card plates 804 simultaneously control the opening and closing of the switches of all circuit breakers 6 on one side of the bracket 5, thereby completing the interlocking of the switch of the circuit breaker 6.

[0022] Furthermore, the size of the limit groove 801 is consistent with the size of the limit block 802, and two groups of sliding plates 803 are arranged inside the high-voltage cabinet 1. Through the setting of the limit groove 801 and the limit block 802, the sliding of the sliding plate 803 is made more stable during use.

[0023] Furthermore, a switch is provided on the surface of the circuit breaker 6, and the position of the switch corresponds to the position of the clamping plate 804. Through the setting of the clamping plate 804, the opening and closing of the switch are made more stable during use.

[0024] Furthermore, multiple groups of ventilation holes 2 are opened on one side surface of the high-voltage cabinet 1, and the multiple groups of ventilation holes 2 are distributed at equal intervals. Through the setting of the ventilation holes 2, when in use, the heat generated inside the high-voltage cabinet 1 during operation will pass through the vents 3 and then be discharged through the ventilation holes 2.

[0025] Furthermore, the vents 3 correspond to the vent holes 2, and four groups of foot supports 4 are arranged at the bottom of the high-voltage cabinet 1, and the four groups of foot supports 4 are respectively arranged at the four corners. Through the arrangement of the foot supports 4, when in use, the foot supports 4 will raise the entire high-voltage cabinet 1, thereby avoiding direct contact with the wet ground.

[0026] Furthermore, the splicing mechanism 9 includes a positioning block 901, a sliding block 902, a positioning groove 903, a sliding groove 904, a rotating fixed plate 905, a connecting block 906, a rotating groove 907, a damping shaft 908 and a rotating block 909.

The internal rotation of the groove 907 is connected to the damping shaft 908, and the surface of the damping shaft 908 is fixedly connected to the rotating block 909. Through the setting of the splicing mechanism 9, when it is necessary to control all the switches of the circuit breaker 6, the clamping plates 804 at both ends are first slid through the sliding groove 904. After sliding to the corresponding position, the positioning block 901 will be stuck in the positioning groove 903, and then the rotating fixed plate 905 is rotated to the surface of the connecting block 906 and stuck in the rotating block 909. Then, the rotating block 909 is rotated through the damping shaft 908 to limit the rotating fixed plate 905, thereby completing the fixation of the clamping plates 804 at both ends, so that all the switches of the circuit breaker 6 can be chained.

[0027] Furthermore, the size of the positioning groove 903 is consistent with the size of the positioning block 901, and the size of the sliding groove 904 matches the size of the sliding block 902. Through the setting of the positioning groove 903, when in use, the positioning block 901 enters the positioning groove 903, thereby making the fixation of the two end clamps 804 more stable.

[0028] Working principle: when the switch of the circuit breaker 6 needs to be interlocked, the cylinder 806 is first started. The operation of the cylinder 806 will drive the telescopic rod 805 to push the sliding plate 803 upward. At this time, the card plate 804 will drive the switch of the circuit breaker 6 during the upward movement. The three groups of card plates 804 simultaneously control the opening and closing of the switches of all the circuit breakers 6 on one side of the bracket 5, thereby completing the interlocking of the switches of the circuit breaker 6. In addition, when it is necessary to control the switches of all the circuit breakers 6, first slide the card plates 804 at both ends through the sliding grooves 904, and slide to the corresponding positions. After being positioned, the positioning block 901 will be stuck in the positioning groove 903, and then the rotating fixing plate 905 will be rotated to the surface of the connecting block 906 and stuck in the rotating block 909, and then the rotating block 909 will be rotated by the damping shaft 908 to limit the rotating fixing plate 905, thereby completing the fixation of the clamping plates 804 at both ends, so that all the circuit breakers 6 switches can be interlocked, and the heat generated inside the high-voltage cabinet 1 during operation will pass through the vent 3 and then be discharged through the vent 2. At the same time, the foot support 4 will raise the entire high-voltage cabinet 1, thereby avoiding direct contact with the wet ground.
