Description

Technical Field

[0001] This utility model relates to the field of gas composition detection technology, specifically a standard gas composition stability sensing device. Background Technology

[0002] When using gas for transportation, the purity of the gas affects the performance, and low gas purity may even cause an explosion. Therefore, standard gas component stability sensors are used in gas production and transportation to detect the purity of the gas. Gas purity refers to the stability of gas components. Standard gas component stability sensors are mainly used to detect gas concentration, hence they are also known as gas component detection sensors.

[0003] In order to accurately measure the concentration of gas components, gas composition detection devices need to be calibrated regularly. Too long an interval will affect the accuracy of the detection results, while too short an interval will waste resources. Therefore, gas detection sensors need to be able to record the calibration time, while ensuring the accuracy of the calibration time, to prevent excessively frequent calibration from wasting resources, or prolonged lack of calibration from affecting the accuracy of the gas composition detection device. Utility Model Content

[0019] This invention provides a standard gas component stability sensing device, which has the following advantages:

[0020] (1) This utility model uses a digital adjustment wheel to calibrate the calibration time. At the same time, the user can also adjust the position of the positioning plate so that the positioning plate and the fixing plate clamp the digital adjustment wheel to prevent the digital adjustment wheel from shifting during use, thereby making the recorded calibration time more accurate. When maintenance is performed, the user can check the time recorded by the digital adjustment wheel to confirm the last calibration time and thus determine whether the device has reached the calibration time. This also prevents excessive calibration from causing resource waste, or long-term lack of calibration from affecting the accuracy of the gas composition detection device.

[0021] (2) This utility model rotates the first handle to drive the rotating frame to rotate, so that the digital adjustment wheel on the surface of the rotating frame is hidden, thereby preventing the numbers on the surface of the digital adjustment wheel from being blurred, so that the user can read the numbers on the surface of the digital adjustment wheel more accurately, and thus accurately determine the calibration time.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] This utility model provides a technical solution: Referring to 1-3, in this embodiment, a standard gas component stabilization sensing device includes: a gas detection sensor body 1, a connecting plate 3 symmetrically welded and fixed to the outer surface of the gas detection sensor body 1, a hidden frame 301 fixedly connected between the connecting plates 3, and a rotating frame 302 rotatably connected inside the hidden frame 301; an installation groove 303 is opened inside the connecting plate 3, a worm gear 304 is rotatably connected inside the installation groove 303, and a worm 305 is meshed above the worm gear 304; the rotating frame 302 passes through the connecting plate 3 and its end face is fixed to the outer surface of the worm gear 304 by bolts; an installation tube 401 is fixedly connected to the inner wall of the rotating frame 302, digital adjustment wheels 307 are evenly installed on the outer surface of the installation tube 401, and the worm 305 passes through the connecting plate 3 and its end face is fixed to a first handle 306 by bolts.

[0028] The mounting tube 401 has evenly spaced slots 402 inside, and a positioning plate 4 is slidably connected inside the slot 402. A lead screw 403 is rotatably connected inside the mounting tube 401. The lead screw 403 passes through multiple sets of positioning plates 4 and is threadedly connected to multiple sets of positioning plates 4. A fixing plate 404 is provided on the side of the digital adjustment wheel 307 away from the worm gear 304. The fixing plate 404 is welded and fixed to the outer surface of the mounting tube 401. The mounting tube 401 passes through the hidden frame 301 and a connecting tube 405 is welded and fixed to its end face. The connecting tube 405 is rotatably connected inside the hidden frame 301. The end of the lead screw 403 away from the worm gear 304 passes through the connecting tube 405 and a second handle 406 is fixed to its end face by bolts.

[0029] A display screen 101 is fixed to the outer surface of the gas detection sensor body 1 via a connector. An air passage is opened inside the gas detection sensor body 1. A transport pipe 103 is welded to the top of the gas detection sensor body 1. An output pipe 104 is welded to one end of the transport pipe 103. An alarm 105 is welded to the side of the gas detection sensor body 1 away from the output pipe 104. An input pipe 102 is welded to the input end of the gas detection sensor body 1. A mounting plate 2 is welded to the outer surface of the gas detection sensor body 1. The input pipe 102 and the output pipe 104 are connected through the air passage inside the gas detection sensor body 1. The alarm 105 can remind the user that the composition of the transported gas is unstable by flashing lights and alarm sounds.

[0030] This invention provides a standard gas component stability sensing device, the specific working principle of which is as follows:

[0031] During installation, the user first takes out the bolts and passes them through the mounting plate 2 to install the gas detection sensor body 1 in the designated position. After installation, the user takes out the pipes and installs the output pipe 104 and the input pipe 102 to the corresponding instruments. When installing the gas detection sensor body 1, the user needs to find a position where the gas is evenly distributed for installation.

[0032] During detection, gas enters the gas detection sensor body 1 from the input pipe 102 and then enters the gas passage of the gas detection sensor body 1. A sensor is installed inside the gas passage. The sensor can detect the composition of the gas and convert the detection result into a recognizable electrical signal. The converted electrical signal is displayed on the surface of the display screen 101, which makes it convenient for users to view the composition of the gas. When the composition of the gas is lower than a certain threshold, the alarm 105 will be activated. The alarm 105 will sound and the top light will flash, indicating that the composition of the gas is unstable.

[0033] During calibration, the user first calibrates the device according to the steps. After calibration, the user holds the first handle 306 and rotates it, causing the worm gear 305 to rotate. The worm gear 305 rotates, causing the worm wheel 304 to rotate. The worm wheel 304 rotates, causing the rotating frame 302 to rotate. The rotating frame 302 rotates the internal digital adjustment wheel 307, making the time displayed on the surface of the digital adjustment wheel 307. Then, the user holds the second handle 406 and rotates it, causing the lead screw 403 to rotate. This causes the positioning plate 4 to slide inside the slot 402, separating the positioning plate 4 from the outer surface of the digital adjustment wheel 307. The user then adjusts the time according to the calibration date. The digital adjustment wheel 307 is rotated, for example, June 17, 25 can be adjusted to 250617. After the adjustment is completed, the user holds the second handle 406 to drive the lead screw 403 to rotate, so that the positioning plate 4 slides inside the slot 402, so that the positioning plate 4 and the fixing plate 404 can clamp the digital adjustment wheel 307, so that the position of the digital adjustment wheel 307 is reinforced and the digital adjustment wheel 307 is prevented from shifting, thereby making the calibration more accurate. After the calibration time is adjusted, the user can hold the first handle 306 to drive the rotating frame 302 to rotate inside the hidden frame 301, so that the digital adjustment wheel 307 can be hidden inside the hidden frame 301.
