Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Reference Figure 1-Figure 7 , a temperature and humidity detection device for a distribution cabinet comprises a cabinet 1, and also comprises: a detection capsule 3 with a connecting pipe 301, which is fixedly connected in the cabinet 1; a driving cylinder 5, which is fixedly connected in the cabinet 1; the detection capsule 3 is connected to the driving cylinder 5 through the connecting pipe 301; an alarm cylinder 2 connected with an alarm 201, which is fixedly connected to the top of the cabinet 1; a first sliding plug 501, which is slidably connected in the driving cylinder 5; a push rod 503, which is fixedly connected to the first sliding plug 501; a power supply 7, which is slidably connected in the alarm cylinder 2; a socket 202 is provided in the alarm cylinder 2, and a connecting column 701 is fixedly connected to the power supply 7, and the connecting column 701 matches the socket 202; when the first sliding plug 501 moves up to push the power supply 7 to move, the power supply 7 synchronously drives the connecting column 701 to move up and insert it into the socket 202, and the power supply 7 supplies power to the alarm 201 on the alarm cylinder 2 to alarm.

[0019] It should be noted that the detection capsule 3 is a self-resetting elastic capsule, and an air supply pipe is connected to the detection capsule 3, the air supply pipe is connected to the external environment, and both the air supply pipe and the connecting pipe 301 are provided with a one-way valve.

[0020] Reference Figure 5 A detection cylinder 4 is fixedly connected in the cabinet 1, a first gas pipe 403 and a second gas pipe 402 are fixedly connected to the detection cylinder 4, a second sliding plug 405 is slidably connected in the detection cylinder 4, and a detection part 406 is fixedly connected in the detection cylinder 4.

[0021] It should be noted that the detection portion 406 is anhydrous copper sulfate powder.

[0022] The bottom of the power source 7 is fixedly connected with a driving rod 6 , and a connecting hole 601 is opened on the driving rod 6 . The top of the push rod 503 is fixedly connected with a connecting rod 5031 , and the connecting rod 5031 matches the connecting hole 601 .

[0023] The first magnet 6011 is fixedly connected to the connecting hole 601 . The connecting rod 5031 is an iron rod. The connecting rod 5031 and the first magnet 6011 are attracted to each other.

[0024] An electromagnet 203 is fixedly connected in the alarm cylinder 2 , and a second magnet 702 is fixedly connected to the top of the power source 7 . The electromagnet 203 and the second magnet 702 attract each other.

[0025] Reference Figure 2-Figure 7When in use, the components in the cabinet 1 will gradually emit heat, and the air pressure in the cabinet 1 will gradually increase. At this time, the detection capsule 3 in the cabinet 1 will be squeezed and deformed by the air pressure. At this time, the solenoid valve on the connecting pipe 301 is opened, and the gas in the detection capsule 3 will be blown into the driving cylinder 5 through the connecting pipe 301. The gas entering the driving cylinder 5 will push the first sliding plug 501 to slide. The sliding of the first sliding plug 501 will push the push rod 503 to move up. When the push rod 503 moves up a certain distance, the connecting rod 5031 on the push rod 503 will be inserted into the connecting hole 601 , and attracted by the first magnet 6011 in the connecting hole 601. At this time, when the first sliding plug 501 continues to move upward, it will push the power supply 7 to move upward synchronously. When the power supply 7 moves up a certain distance, the electromagnet 203 is energized. At this time, the second magnet 702 on the power supply 7 will be attracted by the electromagnet 203 and move upward. When the electromagnet 203 and the second magnet 702 are attracted, the connecting column 701 will be inserted into the socket 202. At this time, the power supply 7 will supply power to the alarm 201, and the alarm 201 will emit sound and light to warn the staff that the temperature in the cabinet 1 is too high, so that the staff can take technical cooling measures.

[0026] Reference Figure 3-Figure 5 , Figure 7 When the first sliding plug 501 moves upward, the driving cylinder 5 will also synchronously extract the gas in the detection cylinder 4 through the first gas pipe 403, and then synchronously pull the second sliding plug 405 to slide. When the second sliding plug 405 slides, the detection cylinder 4 will synchronously extract the gas in the cabinet 1 through the second gas pipe 402, and the extracted gas will pass through the detection part 406. When the water content in the extracted air is relatively high, the anhydrous copper sulfate will change color. The staff can observe the color change of the detection part 406 in time through the visual window 101 and the transparent detection cylinder 4, and then quickly analyze and conclude that the air humidity in the cabinet 1 exceeds the standard, so that the staff can make a maintenance response in time.

[0027] It should be noted that when the electromagnet 203 instantly attracts the second magnet 702 to move upward, the first magnet 6011 will not separate from the connecting rod 5031 .

[0028] It should also be noted that the alarm 201 is a commercially available sound and light alarm lamp.

[0029] A third air delivery pipe 504 is fixedly connected to the side wall of the driving cylinder 5 .

[0030] A first spring 502 is fixedly connected to the first sliding plug 501 , and one end of the first spring 502 away from the first sliding plug 501 is fixedly connected to the inner top wall of the driving cylinder 5 .

[0031] It should be noted that an air intake pipe is also connected to the side wall of the driving cylinder 5, and one end of the air intake pipe away from the driving cylinder 5 is connected to an external dry cooling gas tank; it should also be noted that both the air intake pipe and the third air supply pipe 504 are provided with a one-way valve.

[0032] Reference Figure 3 , Figure 4 When the inspection is completed, the electromagnet 203 is powered off, and the cooling gas tank replenishes air into the driving cylinder 5. At this time, the first sliding plug 501 will slide down and reset. After the first sliding plug 501 slides down a certain distance, the power supply 7 slides down to the lowest end of the alarm cylinder 2. When the first sliding plug 501 slides down again, the first magnet 6011 will be separated from the connecting rod 5031.

[0033] Reference Figure 4 By setting the first spring 502, the first sliding plug 501 can be quickly reset. When the first sliding plug 501 is reset, the driving cylinder 5 will draw dry cooling gas from the outside through the intake pipe and store the dry cooling gas in the driving cylinder 5 for the next detection.

[0034] The second sliding plug 405 is fixedly connected to a second spring 404 , and one end of the second spring 404 away from the second sliding plug 405 is fixedly connected to the inner wall of the detection cylinder 4 .

[0035] Reference Figure 5 The second spring 404 can be used to quickly reset the second slide plug 405 . When the second slide plug 405 is reset, the air extracted from the detection cylinder 4 can be squeezed out, and the squeezed air will be discharged to the outside of the cabinet 1 through the fourth air supply pipe 401 .

[0036] A visual window 101 is fixedly connected to the cabinet 1, and the detection tube 4 is a transparent glass tube.

[0037] Reference Figure 1 , Figure 3 , Figure 5 When the second sliding plug 405 is sucked and slides to the right, the air in the cabinet 1 will be drawn into the detection cylinder 4 through the second air supply pipe 402, and the drawn air will pass through the detection part 406. When the water content in the drawn air is relatively high, the anhydrous copper sulfate will change color. The staff can observe the color change of the detection part 406 in time through the visual window 101 and the transparent detection cylinder 4, and then quickly analyze and conclude that the air humidity in the cabinet 1 exceeds the standard, so that the staff can make a maintenance response in time.

[0038] It should be noted that, when the detection part 406 changes color, the staff can replace the detection part 406 during maintenance to facilitate the humidity detection next time.

[0039] The detection tube 4 is fixedly connected with a fourth gas pipe 401 , and both the fourth gas pipe 401 and the second gas pipe 402 are provided with a one-way valve.

[0040] The present invention senses the change of air pressure in the cabinet 1 through the detection capsule 3, and uses the pressure deformation of the detection capsule 3 to drive the power supply 7 to supply power to the alarm 201 to alarm, which can timely warn the staff that the temperature of the cabinet 1 is too high, so that the staff can quickly take cooling measures, effectively avoiding damage to components in the distribution cabinet due to excessive temperature, and greatly improving the safety and stability of the operation of the distribution cabinet; At the same time, the movement of the first sliding plug 501 in the driving cylinder 5 is utilized to draw the air in the cabinet 1 into the detection cylinder 4, and the color change of the detection part 406 in the detection cylinder 4 is observed, so that the staff can make timely maintenance response and prevent electrical failures caused by excessive humidity, thereby further improving the safety and stability of the operation of the distribution cabinet.
