[0002] A voltage relay is an electronic control device that has a control system and a controlled system. It is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic regulation, safety protection, and circuit conversion in the circuit. It is mainly used in relay protection devices for generators, transformers, and transmission lines as a starting element for overvoltage protection or low voltage lockout.

[0003] Publication No. "CN217562481U" discloses "a voltage relay with an alarm function". By setting a buzzer and a flashing light, when the temperature sensor detects that the temperature inside the assembly shell is abnormally high, the control module lights the flashing light and makes the buzzer ring, alerting the operator so that the operator can deal with related problems in time. By setting an electric telescopic rod and a fan, the electric telescopic rod can be extended while the alarm is sounded, driving the two displacement plates to move backward synchronously, so that the matching grooves on the two displacement plates are aligned with the matching grooves on the side walls of the assembly shell left and right, and the fan draws the air out of the assembly shell through the left matching groove, so that the external air is replenished to the inside of the assembly shell through the right matching groove. The voltage relay device is cooled down quickly through heat exchange to prevent the electronic components of the voltage relay device from being damaged in large quantities due to continuous high temperature.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] During use, since the temperature sensor is an electronic device, when the temperature sensor fails, it is impossible to detect the temperature conditions inside the assembly shell and issue an alarm in time, which can easily cause damage to the voltage relay device and affect the use effect and service life of the voltage relay device.

[0006] In view of the above problems, we propose a voltage relay with an alarm structure. Utility Model Content

[0023] The heat of the relay device body 2 is conveniently conducted to the bottom of the bottle body 4 through the heat conducting plate 3. The air inside the bottle body 4 expands due to the heat. Under the action of the connecting tube 6, the balloon 7 is inflated and expanded, and the movable plate 8 is lifted upward. Combined with the activity of the float rod 9 and the upper port of the bottle body 4, the float rod 9 is driven to move upward. As the temperature of the relay device body 2 continues to rise, the extrusion plate 10 is driven upward to contact the alarm switch 11, and the alarm mechanism is turned on to achieve the purpose of high temperature alarm, reduce the use of electronic equipment, and solve the problem in the prior art that the temperature sensor is an electronic device. When the temperature sensor fails, it is impossible to detect the temperature inside the assembly shell 1 and alarm in time, which easily causes damage to the voltage relay device and affects the use effect and service life of the voltage relay device.

[0024] The alarm mechanism includes a buzzer 12 and an alarm light 13. The buzzer 12 is mounted on one side of the top of the assembly shell 1, and the alarm light 13 is mounted on one side of the buzzer 12. The buzzer 12 and the alarm light 13 are connected to the alarm switch 11 through wires.

[0025] A plurality of isolation buffer mechanisms 14 are connected between the upper and lower surfaces of the relay device body 2 and the inner wall of the assembly shell 1 . A dust filter 16 is provided on one side of the assembly shell 1 . A fan 15 is installed on the side of the assembly shell 1 away from the dust filter 16 .

[0026] A battery 17 is installed on the top of the assembly shell 1, and the buzzer 12, the alarm light 13 and the fan 15 are all electrically connected to the battery 17. A controller 18 is installed on the side of the assembly shell 1 close to the fan 15, and the buzzer 12, the alarm light 13, the fan 15 and the battery 17 are all electrically connected to the controller 18.

[0027] An inspection door 19 is movably installed on the front side of the assembly shell 1, which is convenient for staff to inspect and maintain the relay device body 2 inside the assembly shell 1. An installation groove is opened on the side of the assembly shell 1 close to the dust filter 16, and a wiring hole plate 20 is installed in the installation groove. By setting the wiring hole plate 20, the connecting wires between the relay device body 2 and the circuit can be arranged to the outside of the assembly shell 1 through the holes of the wiring hole plate 20.

[0028] Example:

[0029] When in use, when the relay device body 2 repeatedly switches the contacts, causing continuous opening and closing of the arc, causing abnormal heating at the center of the contact part, the temperature inside the assembly shell 1 and the outer wall of the relay device body 2 rises, and under the action of the heat conducting plate 3, the heat is conducted to the bottom of the bottle body 4, causing the air on the lower side of the bottle body 4 to expand due to the heat. Combined with the connecting pipe 6, the heat-expanded air enters the balloon 7, causing the balloon 7 to inflate and become larger, squeezing the movable plate 8 upward, and then pushing the floating rod 9 upward. The upward movement of the floating rod 9 drives the squeezing plate 10 upward;

[0030] As the temperature rises, the volume of air expands, and the extrusion plate 10 is pushed up to contact the alarm switch 11, turning on the alarm light 13 and the buzzer 12, sounding an alarm, and reminding the staff to respond in time, thus achieving the purpose of high temperature alarm. There is no need to use a temperature sensor to monitor the temperature, which solves the problem in the prior art that the temperature sensor is an electronic device, and when the temperature sensor fails, it is impossible to detect the temperature inside the assembly shell 1 and give an alarm in time, which easily causes damage to the voltage relay device and affects the use effect and service life of the voltage relay device;

[0031] When the alarm light 13 and the buzzer 12 are activated, the signal is fed back to the controller 18. Under the action of the controller 18, the fan 15 is started to accelerate the air flow inside the assembly shell 1 to dissipate heat inside the assembly shell 1, thereby achieving the purpose of cooling the relay device body 2 and preventing continuous high temperature from causing a large number of damages to the electronic components inside the relay device body 2, thereby increasing the difficulty of maintenance.

[0032] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. At the same time, the buzzer 12, the alarm light 13, the fan 15, the battery 17 and the controller 18 in the utility model are all purchased on the market, and those skilled in the art can install and use them according to the requirements;
