[0033] By applying the technical solution of the present invention, a gas concentration detection device is used to be installed on a pipeline 1 and detect the gas concentration near the pipeline 1. The gas concentration detection device includes: a seat body 2, a support member 3, a detection body 6, a first connecting member 401 and a second connecting member 402. The seat body 2 is arranged on the pipeline 1. The support member 3 is arranged on the seat body 2. The detection body 6 is connected to the support member 3. The first connecting member 401 is located on one side of the support member 3, and a first bending section is arranged on the first connecting member 401, and the first bending section has a first opening. The second connecting member 402 is located on the other side of the support member 3 and is connected to the detection body 6, and a second bending section is arranged on the second connecting member 402, and the second bending section has a second opening. When the first connecting member 401 is fixedly connected to the second connecting member 402, the first opening and the second opening form a mounting hole, and the support member 3 is fixed in the mounting hole.

[0034] In this way, when the gas concentration detection device needs to be placed at the connection of the pipeline 1, the detection body 6 can be fixed on the support 3 through the first connecting member 401 and the second connecting member 402. The support 3 is arranged on the base 2, and the base 2 is arranged on the pipeline 1. In this way, due to the arrangement of the base 2 and the supporting member 3, the position of the detection body 6 can be adjusted so that the display screen of the detection body 6 can be placed upright, which is convenient for the operator to observe. In addition, the arrangement of the first connecting member 401 and the second connecting member 402 facilitates the connection between the detection body 6 and the supporting member 3. Therefore, the technical solution of the present application effectively solves the problem in the related art that the setting position of the gas concentration detection device needs to be determined according to the connection of the pipeline, which is not convenient for observation.

[0035] In this embodiment, the detection body 6 includes a sensor, a signal processing circuit and a display screen. The sensor is used to detect the presence of a specific gas and convert it into an electrical signal. The signal processing circuit is used to amplify, filter, linearize and digitize the signal output by the sensor for subsequent processing and analysis. The display screen can convert the processed signal into an intuitive digital or graphical display, making it convenient for users to read gas concentration data.

[0036] In this embodiment, the first connecting member 401 is located above the supporting member 3, and the second connecting member 402 is located below the supporting member 3. The first connecting member 401 and the second connecting member 402 constitute a connecting member 4.

[0037] like Figures 1 to 4 As shown, the gas concentration detection device also includes a plug connector 5 connected between the first connector 401 and the second connector 402. The first connector 401 is provided with a first through hole, and the second connector 402 is provided with a second through hole. The plug connector 5 is inserted into the first through hole and the second through hole to fix the first connector 401 and the second connector 402. The provision of the plug connector 5 facilitates the connection between the first connector 401 and the second connector 402, and can conveniently and quickly fix the support member 3 between the first connector 401 and the second connector 402.

[0038] like Figure 5 As shown, in the first embodiment, the plug connector 5 includes a plug connector 501, a clamp connector 503 spaced apart from the plug connector 501, and an insertion rod 502 connected between the plug connector 501 and the clamp connector 503, and the insertion rod 502 passes through the first through hole and the second through hole. The second connector 402 is engaged with the plug connector 501 by a stopper, and the first connector 401 is engaged with the clamp connector 503 by a stopper. The plug connector 501 and the clamp connector 503 have a simple structure and are easy to process. The plug connector 501 and the clamp connector 503 can be engaged on both sides of the first connector 401 and the second connector 402 to connect the first connector 401 and the second connector 402.

[0039] In other embodiments, the first connecting member 401 is stop-matched with the plug connector 501 , and the second connecting member 402 is stop-matched with the clamp connector 503 .

[0040] like Figure 5As shown, in the first embodiment, there are multiple plug rods 502 and multiple card connectors 503, and the multiple plug rods 502 and multiple card connectors 503 are connected one by one. The multiple plug rods 502 are arranged on the plug connector 501 at intervals, and there is a swing gap between every two plug rods 502. In the process of inserting the plug connector 5 into the first through hole and the second through hole, the multiple card connectors 503 abut against the hole wall of the second through hole or the hole wall of the first through hole, so that the multiple plug rods 502 are close to each other. The setting of the swing gap allows the plug rod 502 to swing, so that the plug rod 502 can be maintained in a position where the card connector 503 cooperates with another stopper in the first connector 401 and the second connector 402 without being subjected to external force. The structure of the plug connector 5 is simple and easy to process.

[0041] like Figure 5 As shown, in the first embodiment, the card connector 503 is provided with a first guide bevel and a second guide bevel at intervals in the extension direction of the insertion rod 502. The inclination direction of the first guide bevel is opposite to that of the second guide bevel. When the card connector 503 penetrates into the first through hole or the second through hole, the first guide bevel abuts against the hole wall of the first through hole or the hole wall of the second through hole. The setting of the first guide bevel facilitates the card connector 503 to penetrate into the first through hole or the second through hole. When the card connector 503 penetrates out of the first through hole or the second through hole, the second guide bevel abuts against the hole wall of the first through hole or the hole wall of the second through hole. The setting of the second guide bevel facilitates the card connector 503 to penetrate out of the second through hole or the first through hole.

[0042] like Figure 6 As shown, the specific structure of the connector 5 in the second embodiment is different from that in the first embodiment. In the second embodiment, the connector 5 includes a plug 504, a first rod 505 connected to the plug 504, and a second rod 506 rotatably connected to the first rod 505. The first rod 505 is inserted into the first through hole and the second through hole, and the first connector 401 is matched with the plug 504 stopper. The second connector 402 is matched with the second rod 506 by magnetic attraction. In this way, after the second rod 506 is matched with the second connector 402 by magnetic attraction, the first rod 505 can be better confined in the first through hole and the second through hole, so that the first connector 401 and the second connector 402 are more stably connected.

[0043] In other embodiments, the second connecting member 402 is stop-matched with the plug 504 , and the first connecting member 401 is magnetically matched with the second rod 506 .

[0044] like Figures 1 to 4As shown, the gas concentration detection device also includes a solar power generation device 12 arranged on the base 2. The solar power generation device includes a photovoltaic panel 11, a bidirectional inverter 1202 electrically connected to the photovoltaic panel 11, and a battery 1201 electrically connected to the bidirectional inverter 1202, and the battery 1201 supplies power to the detection body 6. The solar power generation device 12 can supply power to the detection body 6, reducing the setting of external power and simplifying the wiring. The photovoltaic panel 11 can absorb solar energy and convert the solar energy into electrical energy and store it in the battery 1201. In conjunction with the bidirectional inverter 1202, the electrical energy in the battery 1201 can be converted into usable electrical energy to supply power to the detection body 6 and the alarm light 7.

[0045] In this embodiment, the solar power generation device 12 is arranged on the base 2 through the first fastener 13, and the base 2 is arranged on the pipeline 1 through the second fastener 14. The solar power generation device 12 also includes a drive motor 1001 arranged on the base 2 and a transmission rod 1002 drivingly connected to the drive motor 1001, and the photovoltaic panel 11 is connected to the transmission rod 1002. The outer cover of the drive motor 1001 is provided with a motor box 9.

[0046] like Figures 1 to 4 As shown, the solar power generation device 12 also includes a photosensitive sensor, a controller 8 connected to the photosensitive sensor signal, and a driving structure 10 connected to the controller 8. The photosensitive sensor is used to detect the position of the sun, and the driving structure 10 drives the photovoltaic panel 11 to rotate. In this way, the photosensitive sensor can detect the position of the sun and transmit the detected position signal to the controller 8, and the controller 8 controls the driving structure 10 so that the angle of the photovoltaic panel 11 can be better oriented to the position of the sun, so that the photovoltaic panel 11 can receive more solar energy.

[0047] In this embodiment, the photovoltaic panel 11 can be replaced with a solar photovoltaic film. The flexible solar photovoltaic film can be easily installed on various surfaces, such as the exterior walls of buildings, roofs, etc., to maximize the absorption of solar energy and convert it into electrical energy. The battery 1201 can be replaced with a lithium battery or other high-efficiency energy storage system. Selecting a high-efficiency lithium-ion battery or other chemical energy storage system can improve energy density and cycle life, and can effectively store the electrical energy collected from the photovoltaic panel 11. The bidirectional inverter 1202 can be an intelligent inverter. In conjunction with microgrid technology, it can more accurately control the conversion and supply of electrical energy, ensure continuous power supply to the equipment when needed, and optimize energy management.

[0048] like Figures 1 to 4 As shown, the driving structure 10 includes a driving motor 1001 and a transmission rod 1002 drivingly connected to the output end of the driving motor 1001, and the photovoltaic panel 11 is arranged on the transmission rod 1002. The driving structure 10 has a simple structure and is easy to process.

[0049] like Figures 1 to 4 As shown, the gas concentration detection device also includes an alarm light 7, the detection body 6 is connected to the controller 8 by signal, and the controller 8 is connected to the alarm light 7 by control. When the detection body 6 detects that the gas concentration exceeds a preset value, the controller 8 can send a signal to the alarm light 7 so that the alarm light 7 responds in time, so that the operator can be informed of the gas leakage in time.

[0050] In this embodiment, the gas concentration detection device is used to detect the gas concentration of carbon dioxide. The carbon dioxide concentration detection device is suitable for detecting the carbon dioxide concentration in industrial, agricultural and residential environments, outputting 4mA to 20mA analog signals and two-way switch signals, and can directly control the controlled equipment or output data to any electronic analog controller. In the industrial field, carbon dioxide emissions have certain standards. In order to ensure the emission standards, a corresponding carbon dioxide concentration detection device is required during the carbon dioxide detection process of the corresponding exhaust gas. The carbon dioxide concentration detection device has different models according to the usage, which are divided into industrial pipeline fixed type and handheld type. Among them, the pipeline fixed type is the most common in industrial pipeline transportation.

[0051] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0053] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
