[0002] A high-voltage DC relay is a switching device specially used in high-voltage DC circuits. Its main function is to control the on and off of the circuit through electromagnetic force, thereby achieving current control. High-voltage DC relays are widely used in situations where high-voltage DC signals need to be controlled, such as electricity, automation control, transportation, etc.

[0003] With the widespread use of high-voltage DC relays, there are certain requirements for the use and life of the equipment. Therefore, the installation of the equipment during use is one of the factors that determine the stability of performance. The installation of high-voltage DC relays requires special attention to safety and specifications to ensure that the equipment can work normally in a high-voltage environment and prevent accidents.

[0004] In the prior art, high-voltage DC relays are mostly fixed to equipment by multiple sets of screws to prevent the high-voltage DC relays from loosening due to vibration or other factors. However, high-voltage DC relays are installed by means of multiple sets of screws, which makes installation more complicated. Moreover, after a long period of time, if the high-voltage DC relay is damaged or its service life is reached, the staff needs to replace the high-voltage DC relay.

When the relay body 1 is energized, the wind systems inside the two sets of bellows 18 are started, so that airflow is generated inside the two sets of bellows 18. The airflow enters the two sets of bellows 18 through the two sets of air inlet ducts 19, and one end of the two sets of air inlet ducts 19 are respectively connected to the two sets of dust boxes 20, so negative pressure is generated inside the two sets of dust boxes 20.

The outer walls of the two groups of movable plates 26 are movably connected to the inner wall of the first slide groove 30, and the movable seat 4 is moved laterally, so that the first slider 24 and the second slider 28 are displaced inside the first slide groove 30 and the second slide groove 31 respectively, thereby adjusting the position of the movable seat 4 and the relay body 1, and the two groups of movable plates 26 are displaced outward, and the two groups of movable plates 26 squeeze the inner wall of the first slide groove 30, thereby improving the stability of the first slider 24 inside the first slide groove 30, and further improving the stability of the movable seat 4 after movement.

[0057] The working principle of the present invention is as follows: when the staff installs the high-voltage DC relay, the staff first installs the base 29 and the movable seat 4, and the staff respectively fixes the multiple sets of fixing blocks 32 on the equipment through multiple sets of screws, with the air outlet slot 23 facing upward and the limit slot 6 facing downward;

[0058] When the base 29 and the movable seat 4 are installed, the staff pulls the limit block 7 from one end of the limit block 7 to move it, so that the limit block 7 is separated from one end of the installation groove 5, and the one end of the installation groove 5 is opened, and then the installation column 2 at the bottom end of the relay body 1 is inserted into the installation groove 5 from one end of the installation groove 5. After the installation column 2 enters the installation groove 5, the staff releases one end of the limit block 7, and the spring 9 pushes the limit block 7 to reset, thereby closing one end of the installation groove 5, blocking the installation column 2, and preventing the installation column 2 from sliding out of the installation groove 5;

[0059] When the mounting column 2 enters the mounting groove 5, the mounting column 2 moves inside the mounting groove 5, driving the toothed plate 3 to move inside the mounting groove 5, and the toothed plate 3 is meshed and connected with the driving gear 11, so the driving gear 11 rotates, thereby driving the driving shaft 10 to rotate, and the two ends of the driving shaft 10 are respectively connected with the two sets of transmission shafts 12 through synchronous belts, and the two sets of transmission shafts 12 rotate, thereby driving the two sets of transmission bevel gears 13 to rotate, and the two sets of transmission bevel gears 13 are respectively meshed and connected with the two sets of linkage bevel gears 15, and the two sets of linkage bevel gears 15 rotate, thereby driving the two sets of linkage shafts 14 to rotate, and the outer walls of the two sets of linkage shafts 14 are respectively threadedly connected with the inner walls of the two sets of limit columns 17, so the two sets of limit columns 17 move downward, and one end of the two sets of limit columns 17 presses and fixes the two ends of the relay body 1, thereby improving the stability of the relay body 1 after installation;

[0060] After the relay body 1 is installed, if the relay body 1 is connected to the device, there is a certain distance between the connection end of the relay body 1 and the connection end of the device. If the length of the connector is not enough, the connector cannot connect the connection end of the relay body 1 to the connection end of the device. The staff moves the movable seat 4 horizontally, so that the first slider 24 and the second slider 28 are displaced in the first slide groove 30 and the second slide groove 31 respectively, thereby adjusting the position of the movable seat 4 and the relay body 1, improving the practicality of the high-voltage DC relay, and there is no need to disassemble and adjust the installation area of ​​the base 29;

[0061] When the movable seat 4 moves, the relay body 1 is powered on, and the wind systems inside the two sets of bellows 18 are started, so that airflow is generated inside the two sets of bellows 18, and the airflow enters the air outlet slot 23 through the two sets of air outlet ducts 22. The air outlet slot 23 discharges the airflow, forming a simple airflow protection wall for the relay body 1, reducing the dust adhesion on the outer wall of the relay body 1, and accelerating the airflow velocity on the outer wall of the relay body 1, thereby improving the heat dissipation effect of the relay body 1;

[0062] When the airflow enters the air outlet slot 23, part of the airflow enters the inflatable block 25 through the air inlet pipe 27, so that the inflatable block 25 expands, thereby driving the two sets of movable plates 26 to move outward. The two sets of movable plates 26 squeeze the inner wall of the first slide slot 30, thereby improving the stability of the first slider 24 in the first slide slot 30, and further improving the stability of the movable seat 4 after moving;

[0063] When airflow is generated inside the two groups of bellows 18, the airflow enters the two groups of bellows 18 through the two groups of air inlet ducts 19 respectively, and one end of the two groups of air inlet ducts 19 is respectively connected to the two groups of dust collecting boxes 20, so negative pressure is generated inside the two groups of dust collecting boxes 20, and the negative pressure is transmitted to the dust suction ports at one end of the two groups of limit columns 17 through the two groups of dust suction pipes 21. The two groups of dust suction ports respectively absorb dust from the connecting ends of the outer wall of the relay body 1, reduce the dust attached to the connecting ends of the relay body 1, improve the connection stability between the relay body 1 and the equipment, and further improve the practicality of the relay body 1.
