Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: an environmental protection gas ring main switch with air leakage alarm function, comprising:

[0026] Environmental protection gas ring main switch body 1;

[0027] The surface of the environment-friendly gas ring main transformer body 1 is provided with a double alarm mechanism 2 for alarming mechanical leakage and electronic pressure of the environment-friendly gas ring main transformer body 1.

[0028] The surface of the environment-friendly gas ring main transformer body 1 is provided with a double alarm mechanism 2 for alarming mechanical leakage and electronic pressure of the environment-friendly gas ring main transformer body 1.

[0029] The surface of the environment-friendly gas ring main transformer body 1 is provided with a double alarm mechanism 2 for alarming mechanical leakage and electronic pressure of the environment-friendly gas ring main transformer body 1.

[0030] It is worth noting that when the protective frame 31 is impacted, the movement of the protective frame 31 will drive the push rod 301 to swing, and the two shock absorbers 32 will assist in energy absorption.

[0031] Specifically, the anti-collision protection mechanism 3 is arranged on the surface of the environment-friendly gas ring main transformer body 1 to absorb and disperse the collision energy, thereby protecting the internal circuit elements of the environment-friendly gas ring main transformer body 1 from damage, which not only prolongs the service life of the equipment, but also ensures the stable operation of the power grid, avoiding the decomposition of the internal gas into toxic substances when the environment-friendly gas ring main transformer body 1 is impacted by external force without an energy absorption mechanism.

[0032] The double alarm mechanism 2 includes a detection instrument 21 arranged on the surface of the environment-friendly gas ring main transformer body 1, an electronic pressure detector 22 and a mechanical leakage alarm assembly 20 arranged on the top of the environment-friendly gas ring main transformer body 1, and the detection instrument 21 is electrically connected with the electronic pressure detector 22 and the mechanical leakage alarm assembly 20.

[0033] In this embodiment, when the gas in the environment-friendly gas ring main transformer body 1 leaks, the internal pressure of the environment-friendly gas ring main transformer body 1 decreases, the return spring 205 pushes the floating piston 204 to move downward until the bottom stopper 4 of the floating piston 204 is located between the infrared generator and the infrared receiver, thereby issuing an alarm, and the electronic pressure detector 22 detects the internal pressure of the environment-friendly gas ring main transformer body 1, thereby achieving double protection.

[0034] The mechanical air leakage alarm assembly 20 comprises a sealing cylinder 201 communicated at the top of the environment-friendly gas ring main tank body 1, an infrared emitter 202 inlaid on the front surface of the sealing cylinder 201, an infrared receiver 203 arranged on the back surface of the sealing cylinder 201, and a floating piston 204 clamped on the top of the inner wall of the sealing cylinder 201 through a reset spring 205;

[0035] Specifically, the infrared alarm is composed of a transmitter and a receiver. The transmitter emits infrared rays, and when the infrared rays are blocked or encounter obstacles, the alarm will be triggered. The receiver includes optical system, amplifier, optical sensor, signal processor and other components, which is responsible for receiving the infrared rays emitted by the transmitter, and converting the optical signal into an electrical signal through a photoelectric sensor, and transmitting the signal to the alarm controller after analysis and processing by the signal processor.

[0036] The bottom of the floating piston 204 is fixedly installed with a baffle 4, and the inside of the reset spring 205 is provided with an extension rod 5;

[0039] It should be noted that the movement of the protection frame 31 will drive the push rod 301 to swing, the push rod 301 will drive the push block 302 to move, and the rod body 303 will drive the piston column 304 to move in the sealing seat 305. Since the surface of the piston column 304 is tightly attached to the inner wall of the sealing seat 305, the movement of the piston column 304 causes the air in the sealing seat 305 to be compressed, thereby generating a damping force to absorb the impact force.

[0040] The push block 302 is provided with a groove 6 on one side, and the groove 6 is provided with a pulley 7 inside, and the surface of the pulley 7 is attached to the surface of the environment-friendly gas ring main tank body 1;

[0041] The pulley 7 is arranged on one side of the push block 302, and when the push block 302 is extruded by the push rod 301, one side of the pulley 7 on the surface of the push block 302 is located on the surface of the environment-friendly gas ring main tank body 1 for sliding, thereby achieving the purpose of auxiliary support for the push block 302.

[0042] The back of the two protective frames 31 is provided with a protective plate 8, the surface of the protective plate 8 is provided with a plurality of limiting blocks 9, and the surface of the protective frame 31 is provided with limiting grooves 10 for sliding of the limiting blocks 9;

[0043] The two protective frames 31 can slide on the protective plate 8 when being impacted, and the protective plate 8 can effectively protect the back of the environment-friendly gas ring network cabinet body 1.

[0044] When the environment-friendly gas ring network cabinet body 1 leaks, the internal pressure of the environment-friendly gas ring network cabinet body 1 is reduced, the reset spring 205 pushes the floating piston 204 to move downward until the bottom stopper 4 of the floating piston 204 is located between the infrared generator and the infrared receiver, so that an alarm is sent, and the electronic pressure detector 22 is used to detect the internal pressure of the environment-friendly gas ring network cabinet body 1, so that a double protection effect is achieved.
