Description

Technical Field

[0001] The invention relates to the technical field of gas detection, and in particular to a sulfur hexafluoride test tail gas emission warning device. Background Art

[0002] When conducting gas tests on sulfur hexafluoride equipment in a substation, a rubber hose is usually used to discharge the test exhaust gas to a low-lying area several meters away from the test personnel; Since the SF6 gas in the running equipment will produce FH and other toxic substances due to the arcing effect, inhalation of which will seriously threaten human health. However, low-lying areas are generally only simply placed with warning signs such as notice boards. Such warning signs are not obvious and cannot effectively prevent other workers on site from entering by mistake. In particular, workers on site are not clear about the exhaust emission location or have a weak sense of safety, and are very likely to enter the exhaust emission area by mistake. Due to the inhalation of sulfur hexafluoride gas, they are injured, which poses a great safety hazard. Therefore, the present invention proposes a sulfur hexafluoride test exhaust emission warning device to solve the problems existing in the prior art. Summary of the invention

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention. Example 1

[0016] according to Figure 1 , 2 As shown, this embodiment proposes a sulfur hexafluoride test tail gas emission warning device, including a housing 1, a scanning radar 2 and a warning light 3, wherein the scanning radar 2 is rotatably arranged at one end of the top of the housing 1, and the warning light 3 is arranged at the other end of the top of the housing 1, a display screen 4 is arranged at one end of the front side of the housing 1, and a buzzer 5 is arranged above the other end of the front side of the housing 1, a control panel 6 is arranged on the housing 1 below the buzzer 5, a gas sensor 7 is arranged below the housing 1, and a master control unit for controlling the scanning radar 2, the warning light 3, the display screen 4, the buzzer 5 and the gas sensor 7 is arranged inside the housing 1; The gas sensor 7 is connected to the tail end of the exhaust pipe and is used to detect the exhaust gas content. When the exhaust gas content triggers the threshold, the buzzer 5 is triggered through the main control unit. The scanning radar 2 is used to detect the approach of a person, and when a human body is detected, the buzzer 5 and the warning light 3 are triggered through the main control unit. The gas sensor 7 can detect the SF6 gas concentration at the discharge point, and the alarm concentration limit can be set through the control panel 6. The SF6 flow, concentration, power and other data are displayed in real time on the display screen 4. Since the SF6 gas in the running equipment will produce a variety of toxic substances such as FH due to the arcing action, inhalation will seriously threaten the health of the human body. The alarm concentration limit is set, and the test is carried out indoors or in a place with poor exhaust effect. When the SF6 gas concentration at the discharge point reaches the safety specified value (1000ppm), the buzzer 5 will be triggered to send an alarm signal to remind the operator to control the flow, reduce the SF6 concentration emission, and reduce the on-site SF6 concentration to below the specified value through the exhaust facilities. The scanning radar 2 has an infrared detection function. The radar rotates 360° when working. Its function is to detect whether there is anyone nearby. Once it detects someone nearby, it will immediately send out an alarm signal (voice) through the buzzer 5, and the warning light 3 will flash to remind nearby personnel to stay away from the place immediately to prevent SF6 gas poisoning. Because there are many teams and personnel on site, it is inevitable that they will gather together. SF6 is colorless and odorless and difficult to identify. It is easy for workers to walk nearby and inhale poisonous gas and be poisoned. The scanning radar 2 can accurately detect the workers near the gas discharge, which plays a good role in reminder and safety protection.

The second single-chip processor 11 is connected to the scanning radar 2 to control the opening and closing of the scanning radar 2 and transmit data to the master control processing chip 9. The master control processing chip 9 is used to decode and analyze the data of the gas sensor 7 and the data of the scanning radar 2, and the driving end of the master control processing chip 9 is connected to the audio controller 12 and the warning light 3. The master control processing chip 9 is used to drive the audio controller 12 and the warning light 3 according to the data decoding and analysis results, and the audio controller 12 is used to control the opening and closing of the buzzer 5. The scanning radar 2 is controlled by the internal second single-chip processor 11. After the radar is turned on, it can rotate 360 ​​degrees continuously to continuously monitor the people in the nearby environment. The working mode can be controlled by setting parameters, such as starting to rotate and detect after turning on, or starting to detect when the concentration reaches the standard value. The gas sensor 7, controlled by the first single-chip processor 10, is installed under the device to monitor the concentration of SF6 gas discharged there in real time. Once the emission concentration exceeds the safety standard of 1000ppm, the gas detection module 7 will start the buzzer 5 to send out an alarm signal. The scanning radar 2, the gas sensor 7, the warning light 3, and the buzzer 5 have a coordinated and linked effect. When the gas sensor 7 detects that the gas concentration exceeds the standard, it will turn on the buzzer 5 and the warning light 3, and at the same time start the scanning radar 2 to start detecting whether there are people nearby. When a person is found, a voice reminder will be issued to remind the person to evacuate.

[0019] The output end of the master control processing chip 9 is connected to the display screen 4, and the master control processing chip 9 is used to output the data decoding analysis results to the display screen 4 for display, so that the management personnel can obtain data in real time.
