Technical Field

[0001] This invention relates to the field of hydrogen sulfide technology, and in particular to a hydrogen sulfide content detection device. Background Technology

[0002] In industrial plants, it is necessary to inspect industrial gas pipelines for leaks of hydrogen sulfide gas. Chinese patent application number "CN202210244386.5" discloses a hydrogen sulfide content detection device, including a mounting block, rollers, a bracket, a detector, and pipes. Rollers are rotatably mounted on the lower left and right sides of the mounting block, and a bracket is mounted on top of the mounting block. A detector is mounted on the upper part of the bracket, and pipes are connected to the upper left and right sides of the detector, with the upper parts of the pipes passing through the top of the bracket. The straight pipe moves downwards into the biogas digester to detect hydrogen sulfide gas inside, but it is not suitable for collecting and detecting gas from industrial pipelines. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a hydrogen sulfide content detection device to solve the problem that existing devices cannot detect hydrogen sulfide in industrial pipelines.

[0004] To achieve the above objectives, the present invention provides a hydrogen sulfide content detection device, comprising a housing, an infrared detector installed inside the housing, a support plate installed above the housing, a plurality of adjusting electric cylinders for adjusting the height of the support plate installed between the housing and the support plate, a through hole in the middle of the support plate, a ventilation pipe passing through the through hole, one end of the ventilation pipe being connected to the infrared detector via a telescopic tube, and a gas collection assembly installed at the other end of the ventilation pipe, an adjusting component for adjusting the angle and position of the gas collection assembly installed between the support plate and the gas collection assembly, and a suction pump also installed on the ventilation pipe.

[0005] Optionally, the gas collection assembly includes an arc-shaped cover with a cavity in the middle. Several air intake holes are evenly distributed on the inner arc surface of the arc-shaped cover, and an air outlet hole is opened on the outer arc surface of the arc-shaped cover. One end of the ventilation pipe is connected to the air outlet hole. A one-way valve is installed on one side of the arc-shaped cover, and a sealing assembly for sealing the air intake holes is installed on the arc-shaped cover. When the sealing assembly seals the air intake holes, the one-way valve prevents the gas in the cavity from overflowing outward.

[0006] Optionally, an arc-shaped plate is slidably mounted on the inner arc surface of the arc-shaped cover. Several through slots are evenly distributed on the arc-shaped plate. Arc-shaped sliding grooves are provided on both sides of the arc-shaped cover. Sliding pins are installed at both ends of the arc-shaped plate. The sliding pins are slidably installed in the arc-shaped sliding grooves. A toggle motor is also installed on the side of the arc-shaped cover. A shift fork is installed at the output end of the toggle motor. One end of the sliding pin is slidably installed in the shift fork.

[0007] Optionally, the adjustment assembly includes four adjustment cylinders, which are respectively hinged to the four corners of the upper surface of the support plate, and the output ends of the adjustment cylinders are respectively connected to the four corners of the outer arc surface of the arc-shaped cover.

[0008] Optionally, the ventilation pipe is also equipped with a venting assembly for discharging gas from the ventilation pipe. The venting assembly includes a gas storage bag, one end of which is connected to an external gas source. A rubber pipe is fitted inside the ventilation pipe, and there is a gap between the rubber pipe and the ventilation pipe. The other end of the gas storage bag is connected to the gap.

[0009] Optionally, the gas storage tank is a diaphragm pressure tank, and a first control valve is installed between the gas storage tank and the ventilation pipe.

[0010] Optionally, an exhaust pipe is also installed on the side of the ventilation pipe facing the infrared detector, and a second control valve is installed on the exhaust pipe.

[0011] Optionally, the lower part of the housing is also equipped with several wheels evenly distributed.

[0012] The beneficial effects of this invention are as follows: By adjusting the height of the support plate with an electric cylinder, the gas collection component is brought closer to the industrial pipeline. The angle and height of the gas collection component are adjusted by an adjusting component, so that the gas collection component is as close as possible to the industrial pipeline. The suction pump generates suction in the ventilation pipeline, which in turn generates suction in the gas collection component, drawing the surrounding air to the infrared detector. When there is a hydrogen sulfide gas leak, the infrared detector reacts. The device is easily moved by the wheels. This application, through the setting of the gas collection component, can attract and collect the gas around the industrial pipeline, facilitating the detection of hydrogen sulfide gas in industrial parks.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-6 As shown, a hydrogen sulfide content detection device includes a housing 1, an infrared detector installed inside the housing 1, a support plate 2 installed above the housing 1, several adjusting electric cylinders 3 for adjusting the height of the support plate 2 installed between the housing 1 and the support plate 2, a through hole in the middle of the support plate 2, a ventilation pipe 4 passing through the through hole, one end of the ventilation pipe 4 being connected to the infrared detector via a telescopic pipe 5, and a gas collection assembly installed at the other end of the ventilation pipe 4, an adjusting component for adjusting the angle and position of the gas collection assembly installed between the support plate 2 and the gas collection assembly, an air suction pump 6 also installed on the ventilation pipe 4, and several casters evenly distributed on the lower part of the housing 1.

[0025] The adjusting electric cylinder 3 is a multi-stage electric cylinder. By adjusting the height of the support plate 2, the gas collecting component is brought closer to the industrial pipeline. The angle and height of the gas collecting component are adjusted by the adjusting component to make the gas collecting component as close as possible to the industrial pipeline. The suction pump 6 generates suction in the ventilation pipe 4, which in turn generates suction in the gas collecting component, drawing the surrounding air to the infrared detector. When there is a hydrogen sulfide gas leak, the infrared detector reacts. The device is easy to move by setting up wheels. This application, through the setting of the gas collecting component, can attract and collect the gas around the industrial pipeline, which is convenient for the detection of hydrogen sulfide gas in the industrial park.

[0026] In one embodiment, the gas collection assembly includes an arc-shaped cover 7, with a cavity in the middle of the arc-shaped cover 7. A plurality of air intake holes 8 are evenly distributed on the inner arc surface of the arc-shaped cover 7, and an air outlet hole is opened on the outer arc surface of the arc-shaped cover 7. One end of the ventilation pipe 4 is connected to the air outlet hole. A one-way valve 9 is installed on one side of the arc-shaped cover 7, and a sealing assembly for sealing the air intake holes 8 is installed on the arc-shaped cover 7. When the sealing assembly seals the air intake holes 8, the one-way valve 9 prevents the gas in the cavity from overflowing outward.

[0027] Specifically, an arc-shaped plate 10 is slidably mounted on the inner arc surface of the arc-shaped cover 7. Several through slots 11 are evenly distributed on the arc-shaped plate 10. Arc-shaped sliding grooves are provided on both sides of the arc-shaped cover 7. Sliding pins 12 are mounted at both ends of the arc-shaped plate 10, and the sliding pins 12 are slidably mounted within the arc-shaped sliding grooves. A toggle motor 13 is also mounted on the side of the arc-shaped cover 7. A fork 14 is mounted on the output end of the toggle motor 13, and one end of the sliding pin 12 is slidably mounted within the fork 14. The toggle motor 13 drives the fork 14 to rotate, and the fork 14, by actuating the sliding pins 12, causes the arc-shaped plate 10 to slide, connecting the through slots 11 with the air intake 8. When it is necessary to close the air intake 8, the toggle motor 13 rotates in the opposite direction, causing the fork 14 to drive the arc-shaped plate 10 to slide in the opposite direction.

[0028] In one embodiment, the adjustment assembly includes four adjusting cylinders 15, which are respectively hinged to the four corners of the upper surface of the support plate 2. The output ends of the adjusting cylinders 15 are respectively connected to the four corners of the outer arc surface of the arc-shaped cover 7. Through the coordinated operation of the four adjusting cylinders 15, the angle and height of the arc-shaped cover 7 can be adjusted.

[0029] In one embodiment, the ventilation pipe 4 is also equipped with a venting assembly for discharging gas from the ventilation pipe 4. The venting assembly includes a gas storage tank 16, one end of which is connected to an external gas source. A rubber pipe 17 is fitted inside the ventilation pipe 4, and there is a gap between the rubber pipe 17 and the ventilation pipe 4. The other end of the gas storage tank 16 is connected to the gap.

[0030] Specifically, the air storage tank 16 is a diaphragm-type pressure tank, and a first control valve 18 is installed between the air storage tank 16 and the ventilation pipe 4. An exhaust pipe 19 is also installed on the side of the ventilation pipe 4 facing the infrared detector, and a second control valve 20 is installed on the exhaust pipe 19. To ensure the accuracy of the detection, the residual gas in the ventilation pipe 4 needs to be emptied. At this time, the suction port 8 is sealed with a sealing component, the suction pump 6 continues to work, and outside air passes through the arc-shaped groove via the one-way valve 9. The gas is discharged through the exhaust pipe 19. When the suction pump 6 stops working, the air storage tank 16 inflates into the gap, causing the rubber pipe 17 to deform and expel the gas from the ventilation pipe 4.

[0031] In use, move the device to the detection position, adjust the height of the support plate 2 by adjusting the electric cylinder 3, so that the gas collection component is close to the industrial pipeline, and adjust the angle and height of the gas collection component by adjusting the component so that the gas collection component is as close to the industrial pipeline as possible. Move the motor 13 to drive the fork 14 to rotate. The fork 14 drives the arc plate 10 to slide by moving the sliding pin 12, so that the through groove 11 is connected to the suction hole 8. The suction pump 6 generates suction in the ventilation pipe 4, which in turn generates suction in the gas collection component, drawing the surrounding air to the infrared detector. When there is a hydrogen sulfide gas leak, the infrared detector will react.

[0032] When a new location needs to be inspected, the gas in the arc-shaped cover 7 and the ventilation pipe 4 is first emptied, the air intake hole 8 is sealed with the sealing component, the air intake pump 6 continues to work, the outside air enters the arc-shaped groove through the one-way valve 9, and the gas is discharged through the exhaust pipe 19. When the air intake pump 6 stops working, the air storage bag 16 blows air into the gap, causing the rubber pipe 17 to deform and squeeze the gas in the ventilation pipe 4 out of the ventilation pipe 4.

[0033] This invention facilitates the movement of the device by incorporating wheels, and through the gas collection component, it can attract and collect gas around industrial pipelines, making it convenient for the detection of hydrogen sulfide gas in industrial parks.
