[0049] The embodiment of the present application provides a kind of gas sensor 100, as shown, including acquisition probe 2, shell 3, bottom plate 5 and the connecting mechanism 4 of being arranged in the bottom plate 5; Figure 1

[0050] The acquisition probe 2 is at least partially located in the shell 3, and the shell 3 is connected with the bottom plate 5;

[0051] The connecting mechanism 4 includes first rod body 6, second rod body 7, fixed clamping plate 9 and first elastic element 10;

[0052] The first rod body 6 is fixedly connected to the bottom plate 5, and the second rod body 7 is connected to the first rod body 6;

[0053] The outer periphery of the second rod body 7 is provided with at least two first accommodating grooves 13;

[0054] The number of the first accommodating groove 13, the fixed clamping plate 9 and the first elastic element 10 corresponds, and one end of the first elastic element 10 is fixed to the first accommodating groove 13, and the other end is connected with the fixed clamping plate 9;

[0055] The end of the fixed clamping plate 9 is provided with a lug 1;

[0056] The fixed clamping plate 9 can compress the first elastic element 10 to be at least partially accommodated in the first accommodating groove 10 under the action of radial force.

[0057] ​The radial force described in the embodiment of the present application refers to the force towards the direction of the first accommodating groove 10, which can enable the fixing clamping plate 9 to be accommodated in the first accommodating groove 13. In use, when it is desired to fix the gas sensor 100 at a preset position, such as a ceiling, the fixing clamping plate 9 is under the radial force of the finger, the first elastic member 10 is compressed, and the fixing clamping plate 9 is accommodated in the first accommodating groove 13 of the second rod body 7; then the second rod body 7 is inserted into the gap of the ceiling, and the finger is released; at this time, under the elastic force of the first elastic member 10, the fixing clamping plate 9 is separated from the first accommodating groove 13, and the protruding block 1 is clamped in the gap of the ceiling. The number of the protruding block 1, that is, the number of the fixing clamping plate 9, can be set according to actual needs, such as two or more.

[0058] As a specific embodiment, referring to FIG. 1, Figure 1 Correspondingly, the number of the fixing clamping plate 9 and the first elastic member 10 is two,

[0059] In an embodiment, the connecting mechanism 4 further comprises a second elastic member 8;

[0060] The first accommodating portion 12 is axially arranged in the second rod body 7;

[0061] The second elastic member 8 is arranged in the first accommodating portion 12, and the first rod body 6 abuts against the second elastic member 8;

[0062] The fixing clamping plate 9 is provided with a clamping pin 16 on the side facing the second rod body 7, and the second rod body 7 and the first rod body 6 are provided with through holes 15 corresponding to the clamping pin 16;

[0063] When the second rod body 7 and the first rod body 6 are in the first position, the clamping pin 16 is accommodated in the corresponding through holes 15 of the second rod body 7 and the first rod body 6, and the second elastic member 8 is in an elongated state. When the clamping pin 16 is separated from the corresponding through holes 15 of the second rod body 7 and the first rod body 6, the second elastic member 8 returns to the original state or is in a compressed state.

[0064] In the embodiment of the present application, the relative position of the second rod body 7 and the first rod body 6 is controlled by the extension and contraction of the second elastic member 8. When the second rod body 7 is pulled, the second elastic member 8 is elongated, the second rod body 7 is inserted into the gap of the ceiling, the clamping pin 16 is separated from the corresponding through holes of the second rod body 7 and the first rod body 6, and the first rod body 6 moves towards the second rod body 7 under the elastic force of the second elastic member 8, so that the bottom plate 5 is tightly attached to the ceiling.

[0065] In use, the second rod body 7 is pulled away from the first rod body 6, and the fixed clamping plate 9 is pressed, and the clamping pin 16 on the fixed clamping plate 9 is inserted into the through hole 15, at this time, the relative position of the second rod body 7 and the first rod body 6 is limited; then the end of the second rod body 7 is inserted into the gap between the adjacent two ceiling panels, and then the fingers release the clamping plate 9, the protrusion 1 of the end of the second rod body 7 is clamped in the gap between the two ceiling panels, and the first rod body 6 moves towards the second rod body 7 under the elastic force of the second elastic member 8, that is, the first rod body 6 drives the gas sensor 100 to move towards the ceiling, at this time, the bottom plate 5 presses the ceiling, so that the gas sensor 100 is attached to the ceiling, and the stability of the gas sensor 100 is improved.

[0066] In one embodiment, the bottom plate 5 is provided with a second accommodating groove 11, and one end of the first rod body 6 away from the second rod body 7 is hinged to the second accommodating groove 11. The first rod body 6 can rotate relative to the second accommodating groove 11, and in use, the gas sensor 100 can be fixed at a predetermined position by adjusting the first rod body 6. As shown in the figure, the second accommodating groove 11 penetrates to the edge of the bottom plate 5, and the first rod body 6, the second rod body 7 and the fixed clamping plate 9 can be accommodated in the second accommodating groove 11. Figure 5 As shown in the figure, the second accommodating groove 11 penetrates to the edge of the bottom plate 5, and the first rod body 6, the second rod body 7 and the fixed clamping plate 9 can be accommodated in the second accommodating groove 11.

[0067] In order to further describe the gas sensor 100, the fixing method of the gas sensor 100 is described as follows in the embodiment of the present application:

[0068] In the prior art, the experimental bench in the laboratory is arranged according to the experimental equipment, and after the experimental bench is moved, the gas sensor 100 also needs to be moved to the corresponding position. In the prior art, the gas sensor 100 is usually directly fixed at a certain position in the laboratory, and it is difficult to disassemble, so it is not convenient to adjust the position of the gas sensor 100. Therefore, in order to adapt to the arrangement of the experimental bench and facilitate the placement of the gas sensor 100, the embodiment of the present application provides a gas sensor 100 which is convenient to place and adjust the position. In the use state, first, the second rod body 7 is taken out from the second accommodating groove 11, the fixed clamping plate 9 is pinched and pressed into the first accommodating groove 13, at this time, the protrusion 1 on the fixed clamping plate 9 is retracted into the first accommodating groove 13; then the second rod body 7 is inserted into the gap between the ceiling panels, and then the fingers are released, the protrusion 1 on the fixed clamping plate 9 is inserted into the upper surface of the ceiling panel under the action of the first elastic member 10; Since it is a gas laboratory, the gas flowability needs to be ensured, so when the ceiling is installed, a gap is left between the adjacent ceiling panels to facilitate the flow and discharge of gas, and also to facilitate air exchange; according to the specific position of the experimental bench, the gas sensor 100 is slid along the gap between the ceiling panels to slide the gas sensor 100 above the experimental bench, so that the gas sensor 100 can accurately and quickly collect the leaked gas.

[0069] In one embodiment, as shown in Figure 1 The connecting mechanism 4 further comprises a buckle part 14, one end of which is fixedly connected to the second rod body 7, and the other end is connected to the bottom plate 5. The specific structure of the buckle part 14 can be set according to the shape of the bottom plate 5. The second rod body 7 can be fixed on the bottom plate 5 through the buckle part 14, which facilitates the placement of the gas sensor 100. The buckle part 14 can be separated from the edge of the bottom plate 5 during use, so as to fix the gas sensor 100 at a predetermined position. For example, if the gas sensor 100 is placed and installed on a laboratory bench, at this time the connecting mechanism 4 cannot be used, and the connecting mechanism 4 is buckled on the bottom plate 5 through the buckle part 14, so as to facilitate the placement of the gas sensor 100 and prevent the connecting mechanism 4 from protruding from the second accommodating groove 11 and interfering with the placement of the gas sensor 100.

[0070] In one embodiment, as shown in Figure 2 and Figure 3 The connecting mechanism 4 further comprises a suction cup 18 and a sponge body 19, and the bottom plate 5 is provided with a sliding groove 17 corresponding to the suction cup 18.

[0071] The suction cup 18 is provided with a second accommodating part (not shown in the figure), and the sponge body 19 is arranged in the second accommodating part. The sponge body 19 is adsorbed in the suction cup 18, and the sponge body 19 provides moisture for the suction cup 18, so as to ensure that the suction cup 18 is tightly adsorbed at a predetermined position.

[0072] In a specific embodiment, the suction cup 18 is located below the first rod body 6, so that the first rod body 6 is accommodated in the second accommodating groove 11.

[0073] In the embodiment of the present application, the suction cup 18 serves as an auxiliary connecting structure for fixing the gas sensor 100 at a predetermined device. For example, when the gas sensor 100 is placed on a laboratory bench, if the placement of the gas sensor 100 interferes with the experiment, the gas sensor 100 can be fixed on a vertical side wall of the laboratory bench. At this time, the gas sensor 100 is adsorbed and fixed on the laboratory bench through the suction cup 18, which facilitates the fixation and removal of the gas sensor 100. The sponge body 19 provides moisture for the suction cup 18, so as to ensure the sealing between the suction cup 18 and the laboratory bench.

[0074] The specific structure and connection mode of the sliding groove 17 and the suction cup 18 described in the embodiment of the present application can refer to the detailed description in the prior art, and a person skilled in the art can select according to actual needs. In the embodiment of the present application, the specific structure and connection mode of the sliding groove 17 and the suction cup 18 can not be limited. As a specific embodiment, the sliding groove 17 is annular, the cross section of the sliding groove 17 is T-shaped, and the shape of the suction cup 18 corresponds to the shape of the sliding groove 17.

[0075] In one embodiment, such as Figure 1 As shown, the housing 3 is provided with a handhold 4. The shape of the handhold 4 can be set according to actual needs, for example, it can be set to resemble a finger groove to facilitate holding and moving the gas sensor 100.

[0076] Example 2:

[0077] In one embodiment, such as Figure 5 As shown, the connecting mechanism 4 includes a motor 20, a gear 21, and a rack 22;

[0078] The rotating shaft of the motor 20 is connected to the gear 21, and the gear 21 is meshed with the rack 22. The motor 20 is fixedly connected to the base plate 5. In use, the two ends of the rack 23 are fixed, and the rotation of the rotating shaft of the motor 20 can drive the gear 21 to rotate, thereby driving the gas sensor 100 to perform linear motion.

[0079] As a specific embodiment, the gas sensor 100 is arranged according to the laboratory gas pipeline laying method. For example, if a row of gas pipelines is laid, the gas sensor 100 can be moved back and forth on the row of gas pipelines through the connecting mechanism 4 in this embodiment 2 to realize the gas detection of this row of gas pipelines. Compared with the prior art of using multiple gas sensors 100 for detection, the connecting mechanism 4 in this embodiment 2 can save the investment cost of gas sensor 100.

[0080] It should be noted that the connecting mechanism can be any other structure besides the combination of gear 21 and rack 22 described above. Any combination structure that can satisfy the movement of the gas sensor 100 can be considered as the connecting mechanism 4 in this solution, such as the combination of roller and guide rail, the combination of slider and guide rail, etc.

[0081] Example 3

[0082] Some specific places for experimental analysis and scientific research activities, such as laboratories, various gases are used in the experimental analysis process, some of which are inert gases, some of which are flammable and explosive gases. In order to prevent gas leakage from causing irreversible accidents, a gas monitoring system needs to be established in the specific place. In the prior art, a gas alarm is used to monitor the gas, but the alarm mode of the gas alarm is generally through a sound and light combination mode. This gas monitoring method still needs manual on-site patrol every day, that is, the person in charge needs to personally monitor whether the gas alarm appears alarm. Since the person in charge cannot check the alarm condition of each monitoring area at the same time, if the person in charge cannot learn about the problem in a certain monitoring area in time, serious accidents may occur. Moreover, if the gas alarm is blocked by an object, or the responsible person cannot find the alarm light due to the observation angle, or the person in charge is far away from the gas alarm, or the alarm sound is covered by various noises around the person, the person in charge also cannot hear the alarm sound of the gas alarm, which may eventually lead to a gas leakage accident. Therefore, an intelligent gas monitoring system is urgently needed to solve the above problems.

[0083] The embodiment of the present application provides a gas monitoring system, as shown in the figure, comprising a backend server 200, a backend processor 300 and a gas sensor 100 as described above; Figure 6

[0084] The gas sensor 100 is connected to the backend processor 300 through the backend server 200.

[0085] The collection probe 2 of the gas sensor 100 is integrated with a collection module 101, a positioning module 103 and a communication module 102. The collection module 101 is used to obtain gas data, the positioning module 103 is used to obtain the position information of the gas sensor 100, and the communication module 102 is used to send the gas data and the position information to the backend server 200.

[0086] As a specific embodiment, the positioning module 103 can be a GPS module, which is used to obtain the position information of a building and detailed position information indoors. The communication module 102 can be a WiFi module or a Bluetooth module.

[0087] In one embodiment, as shown in the figure, the backend processor 300 comprises a data storage module 301, a signal conversion module 302 and a remote monitoring module 303. Figure 6

[0088] The signal conversion module 302 is connected to the data storage module 301, is used to process the received gas data to obtain processed gas data, and sends the processed gas data to the data storage module 301.​​

[0089] The data storage module 301 comprises a database for storing the processed gas data and a preset threshold value;

[0090] As shown in Figure 7 The remote monitoring module 303 comprises a display module 3031, a pre-warning module 3032 and an alarm module 3033.

[0091] The display module 3031 is connected with the signal conversion module 302, and is configured to display the received processed gas data.

[0092] The pre-warning module 3032 is connected with the data storage module 301, and is configured to adjust the preset threshold value.

[0093] The alarm module 3033 is connected with the signal conversion module 302 and the pre-warning module 3032 respectively, and is configured to compare the processed gas data with the adjusted preset threshold value, and if the processed gas data exceeds the adjusted preset threshold value, send an alarm information, so that the person in charge can timely grasp the gas data without daily inspection. For example, in a gas laboratory, if gas leakage occurs, the positioning module 103 can quickly locate the accident laboratory position in the experimental area, so that personnel can quickly arrive at the accident laboratory and eliminate the gas leakage danger.

[0094] The display module 3031 and the pre-warning module 3032 are installed in a monitoring room, and the gas data is presented in the form of a data report on the display module 3031 such as a monitoring display. The alarm module 3033 sends the alarm information to the person in charge, such as through 5G / 4G / Wifi network to mobile phone messages and WeChat public number.
