[0001] The present disclosure relates to the field of gas detection, and in particular, to a gas detector. Background Art

[0002] During the production and construction of mines, gas will gush out from the surrounding rock of tunnels, coal seams, and goafs. When the gushing gas gathers to a certain concentration in a certain place, it may cause an accident. Therefore, it is necessary to monitor the gas concentration to ensure safety. When using traditional gas detectors, operators need to hold the gas detector and detect the gas concentration. However, the height of the operators is limited, and the detection of gas concentration at different heights is not comprehensive enough. At the same time, traditional gas detectors cannot measure the gas concentration in fine cracks and holes, which further makes the detection of gas concentration incomplete. Utility Model Content

DETAILED DESCRIPTION

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the directional words used generally refer to the orientation of the relevant components in the actual use state. "Inside and outside" can refer to the inside and outside of the outline of the corresponding component or its location inside or outside the environment, depending on the specific context. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element and do not have order and importance.

[0025] like Figures 1 to 4 As shown, the present disclosure provides a gas detector, including a detector body 1, a telescopic structure 2 arranged on the detector body 1, and a gas sensor 3 arranged on the telescopic structure 2, the telescopic structure 2 is configured to drive the gas sensor 3 to move toward or away from the detector body 1 in a first direction, wherein the telescopic structure 2 includes a shell 21 forming a accommodating space 211, and the gas sensor 3 has a storage position that is completely accommodated in the accommodating space 211.

[0026] It should be noted that the first direction mentioned above can be referenced to the detector body 1, which is convenient for the arrangement of the telescopic structure 2 and for the use of operators. Generally speaking, the gas sensor 3 needs to be set at the upper end of the detector body 1, and the first direction can be referenced to the detector body 1, which is the up and down direction of the detector body 1, that is, the first direction is from the lower end of the detector body 1 to the upper end of the detector body 1. In this way, the telescopic structure 2 can have sufficient installation space on the detector body 1, which is also convenient for operators to use. At this time, the telescopic structure 2 can drive the gas sensor 3 to move toward or away from the detector body 1 in the up and down direction of the detector body 1. For details, please refer to Figures 1 to 4 , further Figure 3 The drawing direction is referenced. Figure 3 The up-down direction of the drawing is the up-down direction of the detector body 1 .

[0027] Through the above technical solution, when the operator needs to detect the gas concentration, the first direction can be made to correspond to the detection direction of the gas sensor 3 when in use, so that the position of the gas sensor 3 in the detection direction can be adjusted by the telescopic structure 2, so that the gas sensor 3 covers a larger range in the detection direction, ensuring the comprehensiveness of the detection of the gas concentration. When the operator needs to detect the gas concentration at different heights, the first direction can be made to correspond to the height direction, so that the position of the gas sensor 3 in the height direction can be adjusted by the telescopic structure 2, so that the gas sensor 3 covers a larger range in the height direction, ensuring the comprehensiveness of the detection of the gas concentration. When the operator needs to detect the gas concentration at locations such as slits and holes, the first direction can be made to correspond to the direction of extending into the slits or holes, so that the position of the gas sensor 3 in the direction of extending into the slits or holes can be adjusted by the telescopic structure 2, so that the gas sensor 3 can go deeper into the slits or holes, ensuring the comprehensiveness of the detection of the gas concentration. When the gas sensor 3 is not in use, it can also be in the storage position, so that the gas sensor 3 can be completely accommodated in the accommodating space 211. The shell 21 can protect the gas sensor 3 and prevent the gas sensor 3 from being damaged during the transportation of the gas detector.

[0028] The telescopic structure 2 may include a driving motor 22 and a telescopic rod 23 disposed in the accommodating space 211, the telescopic rod 23 extending in a first direction, the gas sensor 3 disposed on the telescopic rod 23, and the output shaft of the driving motor 22 connected to the telescopic rod 23, so as to drive the gas sensor 3 to move in the first direction through the telescopic rod 23. The driving motor 22 here may be a self-locking small driving motor 22, so that when the telescopic rod 23 is extended to a specified position, the driving motor 22 may be self-locking, and used to fix the position of the telescopic rod 23, so that the telescopic structure 2 does not need to be additionally provided with a locking structure for fixing the position of the telescopic rod 23. At the same time, the driving motor 22 drives the gas sensor 3 to move in the first direction through the telescopic rod 23, so that the remote stable movement of the gas sensor 3 can be realized. When the operator detects the gas concentration at the slit and hole, if it is necessary to change the position of the gas sensor 3 in the slit and hole, the driving motor 22 can be directly started. It is no longer necessary to take the gas sensor 3 out of the slit and hole and then adjust the position of the gas sensor 3, thereby ensuring the convenience of the gas detector when in use.

[0029] In some embodiments, the telescopic structure 2 may further include a threaded rod 24 extending along the first direction and a mounting platform 25 threadedly matched with the threaded rod 24, the mounting platform 25 abuts against the inner wall surface of the housing 21, the output shaft of the driving motor 22 drives the threaded rod 24 to rotate, and the telescopic rod 23 is arranged on the mounting platform 25. For details, please refer to Figure 3 When the driving motor 22 is started, the threaded rod 24 is driven to rotate. Since the mounting platform 25 is in contact with the inner wall surface of the housing 21, the mounting platform 25 cannot rotate. At this time, the mounting platform 25 can only move along the threaded rod 24 in the first direction. The telescopic rod 23 arranged on the mounting platform 25 follows the mounting platform 25 to move in the first direction, and further drives the gas sensor 3 to move in the first direction. That is, the driving motor 22 drives the telescopic rod 23 to move by driving the threaded rod 24 and the mounting platform 25, and then drives the gas sensor 3 to move in the first direction through the telescopic rod 23. The threaded combination of the threaded rod 24 and the mounting platform 25 forms a screw transmission, which has a high transmission accuracy and can achieve high-precision positioning control, so that the position control of the gas sensor 3 is more accurate. At the same time, the screw transmission allows bidirectional movement, that is, by reversing the direction of the driving motor 22, the telescopic rod 23 can move forward and backward, ensuring the flexibility and versatility of the telescopic structure 2. In other embodiments, the telescopic rod 23 can be provided with a rack extending along the first direction, and the output shaft of the driving motor 22 is provided with a gear that can mesh with the rack. In this way, when the driving motor 22 is started, the driving motor 22 can directly drive the telescopic rod 23 to move in the first direction through the engagement of the gear and the rack. At this time, the telescopic rod 23 needs to abut against the inner wall surface of the shell 21, and the inner wall of the shell 21 limits the telescopic rod 23 to ensure the moving direction of the telescopic rod 23.

[0030] When the telescopic structure 2 adopts the above-mentioned screw drive, a stopper 26 capable of abutting against the mounting platform 25 may be provided at one end of the threaded rod 24 away from the driving motor 22, so as to prevent the mounting platform 25 from being separated from the threaded rod 24. The stopper 26 can limit the travel of the mounting platform 25 on the threaded rod 24, so as to prevent the mounting platform 25 from being separated from the threaded rod 24 and the gas sensor 3 from being separated from the detector body 1.

[0031] The end of the telescopic rod 23 may be provided with a mounting tube 4, which is detachably mounted on the end of the telescopic rod 23, and the gas sensor 3 is mounted on the telescopic rod 23 through the mounting tube 4. In this way, the gas sensor 3 can be detachably connected to the telescopic rod 23 through the mounting tube 4, which facilitates the maintenance and replacement of the gas sensor 3. At the same time, the gas sensor 3 is mounted on the end of the telescopic rod 23 through the mounting tube 4, which maximizes the moving distance of the gas sensor 3.

[0032] The gas detector may further include a plug-in rod 41 that slidably penetrates the wall of the installation tube 4, and a plug-in slot 42 that can be plugged with the plug-in rod 41 is provided on the telescopic rod 23. Figure 4 , through the plug-in rod 41 and the plug-in slot 42, the installation tube 4 is detachably arranged at the end of the telescopic rod 23, so that a plug-in connection is formed between the plug-in rod 41 and the plug-in slot 42, and the telescopic rod 23 and the installation tube 4 do not need to be fixed to each other using additional fasteners (such as screws, bolts) or adhesives, and it is also convenient for disassembly and maintenance, thereby improving assembly efficiency and flexibility. In other embodiments, structures such as buckles and slots can be provided on the telescopic rod 23 and the installation tube 4, which can also realize a detachable connection between the telescopic rod 23 and the installation tube 4.

[0033] An elastic member 43 may be provided at one end of the plug rod 41 away from the telescopic rod 23. One end of the elastic member 43 is connected to the mounting tube 4, and the other end is connected to the plug rod 41. The elastic member 43 is used to make the plug rod 41 abut against the bottom of the plug slot 42. The elastic member 43 can prevent the plug rod 41 from detaching from the plug slot 42. When the plug rod 41 moves in a direction away from the plug slot 42, the elastic member 43 will be pulled so that the elastic member 43 generates an elastic force in the opposite direction, preventing the plug rod 41 from moving in a direction away from the plug slot 42, and allowing the plug rod 41 to always abut against the bottom of the plug slot 42. Figure 4 , and Figure 4For example, when the plug rod 41 moves to the left away from the plug slot 42, the elastic member 43 will be pulled so that the elastic member 43 generates an elastic force to the right, preventing the plug rod 41 from moving away from the plug slot 42, and allowing the plug rod 41 to always abut against the bottom of the plug slot 42. Only when the operator manually operates the plug rod 41, the plug rod 41 will overcome the elastic force generated by the elastic member 43 and detach from the plug slot 42. The elastic member 43 ensures the stability of the installation tube 4, preventing the installation tube 4 from detaching from the telescopic rod 23 when in use.

[0034] The end of the plug rod 41 facing the telescopic rod 23 may be provided with a first magnetic member 44, and the bottom of the plug slot 42 is provided with a second magnetic member 45 attracted to the first magnetic member 44. The first magnetic member 44 can be attracted by the second magnetic member 45, which further prevents the plug rod 41 from being separated from the plug slot 42, thereby ensuring the stability of the plug rod 41.

[0035] A detachable cover plate 5 may be provided at the end of the housing 21 to seal the accommodation space 211. The cover plate 5 may seal the accommodation space 211 to prevent impurities from entering the accommodation space 211 and affecting the use of the gas sensor 3 or the use of the telescopic structure 2.

[0036] The gas detector may further include a handle 11 disposed on the outer wall of the detector body 1. This makes it easier for operators to pick up the gas detector. When detecting gas concentration, the operator can hold the detector body 1 by the handle 11 to determine the position of the gas sensor 3.

[0037] In the present disclosure, the gas sensor 3 mentioned above can be a wireless gas sensor 3, which transmits signals to the detector body 1 through wireless communication technology. It can also be a wired gas sensor 3, so that a channel for wiring can be provided in the telescopic rod 23, so that the wired gas sensor 3 can be electrically connected to the detector body 1.

However, the present disclosure is not limited to the specific details in the above embodiments.
