[0033] Reference Figures 1 to 5The utility model discloses a carbon dioxide production line pipeline gas leak detection device, including carbon dioxide detector 100, clamping mechanism 200 and telescopic mechanism 300, wherein, clamping mechanism 200 is provided with clamping seat 210, and clamping seat 210 is provided with the placement groove 211, and clamping mechanism 200 can fix carbon dioxide detector 100 in the placement groove 211, telescopic mechanism 300 is provided with first sleeve 310 and telescopic link 330, and first sleeve 310 is set up telescopic link 330, and one end of telescopic link 330 is rotatably connected with clamping seat 210. Specifically, in the embodiment, carbon dioxide production line pipeline gas leak detection device utilizes clamping mechanism 200 to fix carbon dioxide detector 100, in the embodiment, carbon dioxide detector 100 adopts the pump suction type carbon dioxide detector 100 of model SKY2000, and the pump suction type carbon dioxide detector 100 detects using infrared principle, and built-in micro sampling pump, and gas sample is inhaled into instrument interior through pump suction sampling mode, and the concentration of carbon dioxide is determined using the absorption characteristic of carbon dioxide to specific wavelength infrared light, with the advantages of high detection precision, strong stability, low error rate and the like. Its advantages include: the suction force size of pump has multiple gears and can be adjusted, and can adapt to different detection requirements, with self-checking function and zero point calibration function, makes gas monitoring more accurate and reliable, with temperature and pressure compensation, can realize the compensation of gas concentration under different temperature and pressure environment, two-stage sound light alarm, and alarm point can be set up by oneself, large capacity lithium polymer rechargeable battery, long working time, the shell adopts high-strength engineering plastics, and is anti-skid, waterproof, dustproof, explosion-proof, and is suitable for a variety of severe environments.

[0034] In the present embodiment, the placement groove 211 on the clamping seat 210 provides a stable placement position for the carbon dioxide detector 100. Through the action of the clamping mechanism 200, it can ensure that the carbon dioxide detector 100 is stably placed in the placement groove 211, and ensure that it will not shake or shift randomly during the working process, thereby providing a basic condition for accurate detection. The telescopic mechanism 300 plays a role in adjusting the position of the carbon dioxide detector 100. The first sleeve 310 is sleeved on the telescopic rod 330, and the telescopic rod 330 can perform telescopic movement in the first sleeve 310. Since one end of the telescopic rod 330 is rotationally connected with the clamping seat 210, when the telescopic rod 330 telescopes, it can drive the clamping seat 210 and the carbon dioxide detector 100 fixed thereon to move in position. For example, when it is necessary to move the carbon dioxide detector 100 to a detection point at a different height or distance, the telescopic rod 330 can be extended or retracted, and at the same time, due to the rotational connection, the angle of the carbon dioxide detector 100 can also be adjusted according to actual needs, so that it can be aligned with the position to be detected, and then the carbon dioxide condition of the corresponding position can be detected. The design of the telescopic mechanism 300 allows the carbon dioxide detector 100 to have a larger adjustment range in the spatial position. The telescopic function of the telescopic rod 330 can change the distance between the instrument and the detection target to adapt to different detection scenes, such as detecting carbon dioxide sources far or near. The rotational connection between the telescopic rod 330 and the clamping seat 210 gives the instrument the ability to adjust the angle, which can better cope with various complex detection environments, so that the instrument can be aligned with detection points in different directions, greatly enhancing the applicability and comprehensiveness of the device.

[0035] In some embodiments of the utility model, telescopic mechanism 300 includes second sleeve 320, first sleeve 310 and second sleeve 320 sliding connection, second sleeve 320 and telescopic rod 330 sliding connection. Specifically, in this embodiment, when need to adjust the position of carbon dioxide detector 100, by operating make second sleeve 320 slide in first sleeve 310, can realize the preliminary position adjustment in a certain range. On this basis, telescopic rod 330 again slide in second sleeve 320, further accurate adjustment position. Because one end of telescopic rod 330 and clamping seat 210 rotationally connected, clamping seat 210 is fixed with carbon dioxide detector 100 again, so along with the sliding of telescopic rod 330 and second sleeve 320 and the rotation between telescopic rod 330 and clamping seat 210, carbon dioxide detector 100 can realize the flexible adjustment of position and angle in three-dimensional space, so as to reach different positions, with different angle to carbon dioxide detection. The two-stage sliding connection mode of first sleeve 310 and second sleeve 320, second sleeve 320 and telescopic rod 330, compared with single-stage telescopic structure, can realize larger range and more accurate position adjustment. Can first slide first sleeve 310 and second sleeve 320 to carry out the coarse adjustment of approximate position, then utilize the sliding of second sleeve 320 and telescopic rod 330 to carry out accurate fine adjustment, make carbon dioxide detector 100 can reach target detection position more accurately, improve the pertinence and accuracy of detection.

[0036] In this embodiment, second sleeve 320 can be set according to the requirement of use multiple, multiple second sleeve 320 is set in turn together, thereby realizing larger range position adjustment.

[0037] In some embodiments of the utility model, the inner peripheral wall of first sleeve 310 is provided with keyway 311, the outer peripheral wall of second sleeve 320 is provided with spline 321, in the elongated state, spline 321 can be embedded in keyway 311. Specifically, in this embodiment, in the elongated state, second sleeve 320 can slide freely in first sleeve 310, at this time spline 321 and keyway 311 do not completely fit. When need to adjust telescopic mechanism 300 to the longest state, the spline 321 of the outer peripheral wall of second sleeve 320 gradually approaches and finally embeds in the keyway 311 of first sleeve 310. This embedded structure plays a locking role in the elongated state, limits the relative rotation and further axial sliding between second sleeve 320 and first sleeve 310, thereby stabilizing the elongated state of telescopic mechanism 300, ensuring that carbon dioxide detector 100 connected by clamping seat 210 at the end of telescopic rod 330 is in a stable position, so as to carry out accurate carbon dioxide detection work.

[0038] In some embodiments of the utility model, telescopic mechanism 300 still includes adjusting rod 340, one end of adjusting rod 340 is rotatably connected with clamping seat 210, the other end of adjusting rod 340 is rotatably connected with telescopic rod 330. Specifically, in the embodiment, the setting of adjusting rod 340 greatly enriches the angle adjustment mode of carbon dioxide detector 100. Through the telescopic cooperation of telescopic rod 330 and the rotation between adjusting rod 340 and clamping seat 210, telescopic rod 330, carbon dioxide detector 100 can be adjusted in multiple dimensions, and can more accurately align carbon dioxide detection sources of different positions and directions, improve the comprehensiveness and accuracy of detection. When it is necessary to adjust the position and angle of carbon dioxide detector 100, telescopic rod 330 is telescoped under the cooperation of first sleeve 310 and second sleeve 320, which will drive the one end of adjusting rod 340 rotatably connected with it to move. Since the other end of adjusting rod 340 is rotatably connected with clamping seat 210, the movement of adjusting rod 340 will cause clamping seat 210 to rotate around the connecting point of adjusting rod 340. In this way, carbon dioxide detector 100 fixed in the placing groove 211 in clamping seat 210 will change the angle. At the same time, the telescopic cooperation of telescopic rod 330 and the rotation of clamping seat 210 driven by adjusting rod 340 enables carbon dioxide detector 100 to be flexibly adjusted in different directions and positions to meet the requirements of detection position and angle in different detection scenes.

[0039] In some embodiments of the utility model, anti-skid line 312 is arranged on the outer peripheral wall of first sleeve 310. Specifically, in the embodiment, anti-skid line 312 significantly increases the friction between the hand and first sleeve 310, effectively preventing the hand from slipping off the sleeve surface during operation. This is particularly important for operating the device in some high-altitude operations or complex environments, avoiding accidents such as equipment falling, damage and personnel injury caused by hand slipping, and ensuring the safety of operators and the surrounding environment.

[0040] In some embodiments of the present utility model, the end of the first sleeve 310 is provided with a cap 350, and the cap 350 is threadedly connected with the first sleeve 310. Specifically, in the present embodiment, the cap 350 is tightly screwed on the end of the first sleeve 310. It plays a role in closing the opening of the end of the first sleeve 310, preventing dust, sundries, water vapor and the like from the outside from entering the inside of the first sleeve 310. Since the second sleeve 320 slides in the first sleeve 310, if impurities enter, the inner wall of the sleeve and the outer peripheral wall of the second sleeve 320 may be abraded, affecting the smoothness of sliding between the two, and thus interfering with the normal operation of the telescopic mechanism 300. When it is necessary to check, clean, repair or replace parts inside the first sleeve 310, the operator can rotate the cap 350 to use the characteristics of threaded connection to unscrew the cap 350 from the end of the first sleeve 310. In this way, the first sleeve 310 can be easily opened, and the internal structure can be operated accordingly. After the operation is completed, the cap 350 is screwed back onto the end of the first sleeve 310 again to restore its closed state and continue to protect the internal structure of the first sleeve 310 from the influence of external factors.

[0041] In some embodiments of the present utility model, the clamping seat 210 is provided with clamping assemblies 220 on both sides of the placing groove 211, and each clamping assembly 220 comprises a clamping block 221 and a driving rod 222. The driving rod 222 is threadedly connected with the clamping seat 210, and one end of the driving rod 222 is rotatably connected with the clamping block 221 through the clamping seat 210. Specifically, in the present embodiment, the clamping assemblies 220 on the clamping seat 210 are used to stably fix the carbon dioxide detector 100. The driving rod 222 is threadedly connected with the clamping seat 210, and the operator rotates the driving rod 222 when it is necessary to fix the carbon dioxide detector 100. Due to the effect of the thread, the driving rod 222 moves axially while rotating. One end of the driving rod 222 passes through the clamping seat 210 and is rotatably connected with the clamping block 221, so that the axial movement of the driving rod 222 drives the clamping block 221 to move towards the carbon dioxide detector 100 inside the placing groove 211. The clamping blocks 221 on both sides move towards each other under the drive of the respective driving rods 222, thereby tightly clamping the carbon dioxide detector 100 in the middle and realizing stable clamping of the instrument. When it is necessary to remove the carbon dioxide detector 100, the driving rod 222 is rotated in the opposite direction, and the driving rod 222 moves in the opposite direction along the axis, thereby driving the clamping block 221 away from the carbon dioxide detector 100 and releasing the clamping state of the instrument, so that the instrument can be conveniently taken out for replacement, maintenance and the like. The threaded connection allows the operator to flexibly adjust the position of the clamping block 221 according to the size of the carbon dioxide detector 100 and the required clamping force, so as to accurately control the movement distance of the clamping block 221, thereby adapting to carbon dioxide detectors 100 of different models and specifications and improving the universality and applicability of the device.

[0042] In some embodiments of the utility model, guiding hole 212 is arranged on clamping seat 210, and guiding portion 223 is arranged at both ends of clamping block 221, guiding portion 223 is slidably arranged in guiding hole 212. Specifically, in this embodiment, when driving rod 222 rotates and drives clamping block 221 to move, guiding portion 223 at both ends of clamping block 221 will slide in guiding hole 212 when clamping assembly 220 works. Guiding hole 212 defines the movement path of guiding portion 223, so that clamping block 221 can only move linearly along the direction perpendicular to the placing groove 211 of carbon dioxide detector 100. This ensures that clamping block 221 can accurately move towards carbon dioxide detector 100 in placing groove 211 during clamping, and always maintains the state of being parallel to the side of the detector, thereby uniformly applying clamping force and avoiding unstable clamping or damage to the detector due to the inclination or deviation of clamping block 221.

[0043] In some embodiments of the utility model, elastic layer 224 is arranged on one side of clamping block 221. Specifically, in this embodiment, when clamping block 221 is driven by driving rod 222 to move towards carbon dioxide detector 100 and is finally clamped, elastic layer 224 first contacts the surface of the detector. Because elastic layer 224 has the characteristic of elastic deformation, it will deform to a certain extent under the action of pressure. This deformation enables elastic layer 224 to better fit the surface profile of the detector, and whether the surface of the detector is flat or not, elastic layer 224 can adaptively and closely contact it. As a buffer medium between clamping block 221 and carbon dioxide detector 100, elastic layer 224 effectively avoids hard damage to the shell and internal elements of the detector during clamping. This is particularly important for expensive and precise detection instruments, which can prolong the service life of the instrument and reduce economic losses caused by equipment damage. Because elastic layer 224 can adapt to the surface shape of the detector, this device can be compatible with various carbon dioxide detectors 100 of different shapes and sizes. Whether the instrument has a regular plane or a special design instrument with a curved or uneven surface, elastic layer 224 can be well fitted, greatly improving the versatility and applicability of the device.

[0044] In some embodiments of the utility model, one end of the driving rod 222 is provided with a knob 225. Specifically, in this embodiment, when the carbon dioxide detector 100 needs to be clamped, the operator holds the knob 225 with his hand. By rotating the knob 225, the driving rod 222 will rotate together because the knob 225 is fixedly connected with the driving rod 222. Because the driving rod 222 is threadedly connected with the clamping seat 210, according to the screw transmission principle, the rotation of the driving rod 222 will be converted into linear movement along the axial direction. This movement drives the clamping block 221 connected with the driving rod 222 to move towards the carbon dioxide detector 100 in the placement groove 211 until the detector is clamped. The setting of the knob 225 enables the operator to control the driving rod 222 easily without the aid of additional tools, just by rotating the knob 225 with his fingers, so as to complete the clamping and unclamping operations of the carbon dioxide detector 100. This simple and intuitive operation mode reduces the operation difficulty, saves the operation time, improves the work efficiency, and is especially suitable for quick operation in various field environments.

[0045] The utility model has been described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
