Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, and more specifically, to a sulfur hexafluoride gas monitoring sensor based on piezoresistive multi-state fusion. Background Technology

[0002] The sulfur hexafluoride gas monitoring sensor based on piezoresistive multi-state fusion is an innovative sensor design, mainly used for monitoring sulfur hexafluoride gas in the air.

[0003] A search revealed that Chinese patent CN218157108U discloses an online monitoring device for sulfur hexafluoride (SF6) gas, comprising a tank and a SF6 detector. The tank has a top cover with an exhaust channel for venting exhaust. The SF6 detector is mounted on the bottom plate of the tank. The lower end of the tank is connected to one end of a connecting pipe, and the other end of the connecting pipe is connected to the lower end of a gas collection trough. The upper end of the gas collection trough is open, and the height of the lowest point of the trough is greater than the height of the highest point of the tank. This patent installs the gas collection trough below a circuit breaker. In the event of a leak, SF6 gas enters the tank through the gas collection trough and connecting pipe, and is detected by the SF6 detector. Multiple gas collection troughs are arranged indoors, sharing a single SF6 detector, effectively reducing the number of detectors required and lowering subsequent maintenance and operating costs. However, the following drawbacks still exist:

[0004] (1) In some enclosed spaces, due to the lack of air circulation, leaks cannot be detected immediately, affecting safety.

[0005] (2) It is difficult to monitor the surrounding air in real time in a comprehensive manner. To address this, a sulfur hexafluoride gas monitoring sensor based on piezoresistive multi-state fusion is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current situation where, in some enclosed spaces, due to poor air circulation, leaks cannot be detected in a timely manner, thus affecting safety.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a sulfur hexafluoride gas monitoring sensor based on piezoresistive multi-state fusion includes a housing, a display screen on the surface of the housing, a monitoring device fixedly installed on the bottom of the inner wall of the housing, the monitoring device being electrically connected to the display screen, a suction device on the surface of the housing, the suction device including a fixed bracket, the fixed bracket being fixedly installed on the bottom of the inner wall of the housing, a rotating fan being provided at the bottom of the fixed bracket, a gas collecting cylinder being fixedly installed at the bottom of the housing, and a ventilation opening being provided at the bottom of the gas collecting cylinder.

[0009] As a preferred technical solution of this utility model, multiple ventilation openings are provided, and the ventilation openings are arranged in a circular array at the bottom of the air collection cylinder. The above design is beneficial to setting multiple ventilation openings, which makes it easier to ventilate the air collection cylinder.

[0010] As a preferred technical solution of this utility model, a fixing member is fixedly installed on the top of the fixed bracket. The fixing member is used to connect the fixed bracket and the outer shell. The above design is beneficial for the fixed bracket to support the fixing member to carry out its work.

[0011] As a preferred technical solution of this utility model, the bottom of the outer shell is provided with a swing device, the swing device includes a rotating rod, the rotating rod is fixedly installed at the bottom of the output end of the rotating fan, the circumferential surface of the rotating rod is provided with a reciprocating spiral groove, the inner wall of the reciprocating spiral groove is slidably installed with a collar, the circumferential surface of the air collecting cylinder is provided with a sliding groove, the inner wall of the sliding groove is slidably installed with a through rod, the through rod is fixedly connected to the collar, an arc-shaped rod is fixedly connected between the two through rods, and a transmission rod is fixedly installed at the bottom of the arc-shaped rod.

[0012] As a preferred technical solution of this utility model, the swing device further includes a fixed block, which is fixedly installed on the circumferential surface of the air collecting cylinder. A rotating shaft is rotatably installed on the surface of the fixed block, and a swing plate is fixedly installed on the side of the rotating shaft away from the fixed block. The above design is beneficial for the fixed block to support the rotating shaft to rotate.

[0013] As a preferred technical solution of this utility model, a torsion spring is provided between the rotating shaft and the fixed block, and the transmission rod is in contact with the swing plate. The above design is beneficial for the rotating shaft to be reset by the torsion spring provided in the fixed block.

[0014] As a preferred technical solution of this utility model, the swing plate is in contact with the gas collecting cylinder, and a spring is provided between the through rod and the sliding groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The air is drawn into the housing through the ventilation opening by the suction device, and the incoming air is monitored in real time by the monitoring device. The monitoring data is then displayed on the screen to prevent the inability to remedy the leak in time in the event of a leak in a confined space due to the slow air flow. This improves the safety of the device.

[0017] 2. By using the swing device, after the transmission rod moves to the top, the torsion spring resets and drives the swing plate to rotate in the opposite direction. This allows the surrounding air to flow into the interior of the housing through the ventilation opening after the swing plate rotates, thereby improving the detection range and angle of the device and enhancing its practicality.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a sulfur hexafluoride gas monitoring sensor based on piezoresistive multi-state fusion, including a housing 1, a display screen 2 on the surface of the housing 1, a monitoring device 3 fixedly installed on the bottom of the inner wall of the housing 1, the monitoring device 3 being electrically connected to the display screen 2, a suction device 4 on the surface of the housing 1, the suction device 4 including a fixed bracket 41, the fixed bracket 41 being fixedly installed on the bottom of the inner wall of the housing 1, a rotating fan 42 being provided at the bottom of the fixed bracket 41, a gas collecting cylinder 43 being fixedly installed at the bottom of the housing 1, and a ventilation opening 44 being provided at the bottom of the gas collecting cylinder 43.

[0029] like Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, a plurality of ventilation openings 44 are provided, and the ventilation openings 44 are arranged in a circular array at the bottom of the air collection cylinder 43.

[0030] like Figure 3 As shown, in a preferred embodiment, based on the above method, a fixing member is further fixedly installed on the top of the fixing bracket 41, which is used to connect the fixing bracket 41 and the outer shell 1.

[0031] like Figure 1 , Figure 2 and Figure 4As shown, in a preferred embodiment, based on the above method, a swing device 5 is further provided at the bottom of the outer shell 1. The swing device 5 includes a rotating rod 51, which is fixedly installed at the bottom of the output end of the rotating fan 42. A reciprocating spiral groove is opened on the circumferential surface of the rotating rod 51, and a collar 52 is slidably installed on the inner wall of the reciprocating spiral groove. A sliding groove is opened on the circumferential surface of the air collecting cylinder 43, and a through rod 53 is slidably installed on the inner wall of the sliding groove. The through rod 53 is fixedly connected to the collar 52. An arc rod 54 is fixedly connected between the two through rods 53, and a transmission rod 55 is fixedly installed at the bottom of the arc rod 54.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the swing device 5 further includes a fixing block 56, which is fixedly installed on the circumferential surface of the air collecting cylinder 43. A rotating shaft 57 is rotatably installed on the surface of the fixing block 56, and a swing plate 58 is fixedly installed on the side of the rotating shaft 57 away from the fixing block 56.

[0033] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, a torsion spring is further provided between the rotating shaft 57 and the fixed block 56, and the transmission rod 55 contacts the swing plate 58, so that the rotating shaft 57 is driven to reset by the torsion spring.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the swing plate 58 contacts the air collecting cylinder 43, and a spring is provided between the through rod 53 and the sliding groove, so that the through rod 53 can be reset by the spring.

[0035] Specifically, when using this piezoresistive multi-state fusion-based sulfur hexafluoride gas monitoring sensor: the rotating fan 42 is started and rotates slowly at a fixed speed. After the rotating fan 42 rotates, it drives the surrounding air to circulate and flow into the gas collection cylinder 43. The air flows into the housing 1 through the vent 44, and the monitoring device 3 monitors the incoming air in real time. The detected data is then displayed on the display screen 2 to prevent the inability to remedy a leak in a confined space due to the slow airflow, thus improving the safety of the device.

[0036] The rotating fan 42 drives the rotating rod 51 to rotate, which in turn drives the reciprocating spiral groove to rotate. The reciprocating spiral groove drives the collar 52 to move up and down reciprocally. The movement of the collar 52 drives the through rod 53 to move reciprocally, which in turn drives the arc rod 54 to move reciprocally. The movement of the arc rod 54 drives the transmission rod 55 to move reciprocally. When the transmission rod 55 moves to the bottom, it will contact the swing plate 58 and drive the swing plate 58 to rotate. After the transmission rod 55 moves to the top, it will reset through the torsion spring and drive the swing plate 58 to rotate in the opposite direction. This allows the surrounding air to flow into the interior of the outer casing 1 through the vent 44 after the rotation of the swing plate 58, thereby improving the detection range and angle of the device and enhancing its practicality.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
