Description

Technical Field

[0001] The utility model relates to the technical field of methane analyzers, in particular to an alarm device based on remote monitoring of methane analyzers. Background Art

[0002] In wetland methane emission research, methane analyzers are used to measure atmospheric methane levels. Open-path methane analyzers typically employ high-precision spectral analysis methods such as tunable diode laser absorption spectroscopy (TDLAS) or wavelength modulation spectroscopy (WMS). These techniques exploit the absorption characteristics of methane molecules to specific wavelengths of laser light for detection.

[0003] After searching, the Chinese patent publication number CN215297141U discloses an open-circuit laser gas analyzer, including a laser emitting part and a laser receiving part. The laser emitting part and the laser receiving part are electrically connected. The laser emitting part is used to emit a laser signal. The laser receiving part can receive the laser signal emitted by the laser emitting part and perform spectral analysis on the laser signal. The laser emitting part and the laser receiving part are each connected to an installation component and a junction box in a one-to-one correspondence. The installation component is used to adjust and fix the laser emitting part and the laser receiving part. The two junction boxes are electrically connected to the laser emitting part and the laser receiving part respectively.

[0004] Since dust will adhere to the surface of the laser emission window during use of the device and affect detection, an automatic pumping system is set up in the prior art to regularly flush the laser emission window. In order to detect the remaining amount of stored cleaning liquid, a liquid level sensor is set inside the liquid storage chamber. Since the liquid level sensor is usually set inside the liquid storage chamber, it is inconvenient to operate when the liquid level sensor needs to be repaired. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] As a further solution of the present invention: the connecting assembly includes a connecting block and a fixing frame, the connecting block is limitedly matched with the top end of the detection cavity, and the fixing frame is connected to the connecting block through a positioning column.

[0009] As a further solution of the present invention: the ultrasonic distance sensor is fixed by the cooperation of the fixing bracket and the connecting block.

[0010] As a further solution of the present invention: a cavity is opened inside the connecting block, a connecting rod is slidably connected to the inner wall of the cavity, the connecting rod is connected to a clamping block, and the clamping block is limitedly matched with the positioning column.

[0011] As a further solution of the present invention: an elastic strip is provided on the inner wall of one end of the cavity, and one side of the elastic strip is in contact with the connecting rod.

[0012] As a further solution of the present invention: a connecting groove is provided at the top of the detection cavity, a limiting block is fixed on the side wall of the connecting groove, and an extrusion rod is slidably connected to the side wall of the bottom end of the connecting groove.

[0013] As a further solution of the present invention: an elastic hook is connected to the bottom end of the connecting block, and the elastic hook is in limited cooperation with the limiting block.

[0014] As a further solution of the present invention: a plurality of blocking plates are fixed to the inner wall of the liquid storage chamber, and the blocking plates are arranged in an array.

[0015] Compared with the existing technology, the utility model provides an alarm device based on remote monitoring of methane analyzers, which has the following beneficial effects:

[0016] 1. The utility model is provided with a detection chamber, a float and an ultrasonic distance sensor. Since the detection chamber is arranged on one side of the liquid storage chamber and is connected to the liquid storage chamber, the position where the float is pushed by the cleaning liquid is detected, thereby realizing the detection of the remaining cleaning liquid in the liquid storage chamber. The detection chamber is not directly exposed to the cleaning liquid, which facilitates the inspection and maintenance of the detection chamber.

[0018] 3. The utility model is provided with a blocking plate, which can divide the interior of the liquid storage chamber into multiple spaces, destroying the propagation path of the wave, causing the wave to gradually decay during the propagation process, thereby reducing the shaking of the cleaning liquid, reducing the fluctuation of the cleaning liquid surface caused by the shaking, and improving the detection accuracy of the detection chamber.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A remote monitoring methane analyzer alarm device, such as Figures 1 to 5As shown, it includes a detection chamber 2 arranged on one side of the open-circuit methane analyzer body 1, and a liquid storage chamber 3 is arranged on the side wall of the open-circuit methane analyzer body 1. The detection chamber 2 is located on one side of the liquid storage chamber 3, and the bottom end of the detection chamber 2 is connected to the liquid storage chamber 3. An ultrasonic distance sensor 6 is installed on the top of the detection chamber 2 through a connecting component. A floating block 5 is slidably fitted on the inner wall of the detection chamber 2. A control module 8 and a communication module 7 are arranged inside the open-circuit methane analyzer body 1.

[0030] The connecting assembly includes a connecting block 10 and a fixing frame 9, the connecting block 10 is limited in cooperation with the top end of the detection chamber 2, the fixing frame 9 is connected to the connecting block 10 through a positioning column 11, and the ultrasonic distance sensor 6 is fixed by the cooperation between the fixing frame 9 and the connecting block 10, a cavity 15 is provided inside the connecting block 10, the inner wall of the cavity 15 is slidably connected with a connecting rod 14, the connecting rod 14 is connected to a card block 12, the card block 12 is limited in cooperation with the positioning column 11, an elastic strip 13 is provided on the inner wall of one end of the cavity 15, and one side of the elastic strip 13 is fitted with the connecting rod 14, a connecting groove 16 is provided on the top end of the detection chamber 2, a limiting block 17 is fixed on the side wall of the connecting groove 16, an elastic hook 18 is connected to the bottom end of the connecting block 10, the elastic hook 18 is limited in cooperation with the limiting block 17, and the side wall of the bottom end of the connecting groove 16 is slidably connected with an extrusion rod 19.

[0031] When there is cleaning liquid inside the liquid storage chamber 3, since the detection chamber 2 is connected to the bottom end of the liquid storage chamber 3, the cleaning liquid inside the detection chamber 2 will be in the same plane as the liquid storage chamber 3, pushing the float 5 to rise, and the ultrasonic distance sensor 6 detects the position of the float 5 to detect the remaining cleaning liquid in the liquid storage chamber 3, and transmits the detection data to the control module 8. The control module 8 compares the data with the preset alarm amount. When the remaining amount is lower than the alarm amount, the communication module 7 reminds the staff through SMS or app message; when repairing the ultrasonic distance sensor 6, press the squeezing rod 19, and the squeezing rod 19 squeezes the elastic hook 18, so that the elastic hook 18 and the limit block 17 limit one end tilt to one side and disengage from the limit block 17, remove the connecting block 10 from the top of the detection chamber 2, and then squeeze the connecting rod 14 to drive the card block 12 to disengage from the positioning column 11, separate the fixing frame 9 from the connecting block 10, and remove the ultrasonic distance sensor 6.

[0032] By setting up the detection chamber 2, the float 5 and the ultrasonic distance sensor 6, since the detection chamber 2 is set on one side of the liquid storage chamber 3 and is connected to the liquid storage chamber 3, the detection float 5 is pushed by the cleaning liquid to the position where the residual cleaning liquid in the liquid storage chamber 3 is detected. The detection chamber 2 is not directly exposed to the cleaning liquid, which facilitates the inspection and maintenance of the detection chamber 2.

[0033] By providing the connection assembly, disassembly is more convenient compared to traditional bolt fixing, and the ultrasonic distance sensor 6 is easy to remove.

[0034] Example 2

[0035] A remote monitoring methane analyzer alarm device, based on Example 1, makes the following improvements, such as Figure 2 As shown, a plurality of blocking plates 4 are fixed to the inner wall of the liquid storage chamber 3 , and the blocking plates 4 are arranged in an array.

[0036] Since the main body 1 of the open-circuit methane analyzer is installed at a high place through the detection support rod during use, the main body 1 of the open-circuit methane analyzer will shake in windy weather. The blocking plate 4 can divide the interior of the liquid storage chamber 3 into multiple spaces, destroying the propagation path of the wave, causing the wave to gradually decay during the propagation process, thereby reducing the shaking of the cleaning liquid, reducing the fluctuation of the cleaning liquid plane caused by the shaking, and improving the detection accuracy of the detection chamber 2.

[0037] By setting up the blocking plate 4, the interior of the liquid storage chamber 3 can be divided into multiple spaces, destroying the propagation path of the wave, causing the wave to gradually decay during the propagation process, thereby reducing the shaking of the cleaning liquid, reducing the fluctuation of the cleaning liquid surface caused by the shaking, and improving the detection accuracy of the detection chamber 2.

[0038] Working principle: When there is cleaning liquid inside the liquid storage chamber 3, since the detection chamber 2 is connected to the bottom end of the liquid storage chamber 3, the cleaning liquid inside the detection chamber 2 will be in the same plane as the liquid storage chamber 3, pushing the float 5 to rise, and the ultrasonic distance sensor 6 detects the position of the float 5 to detect the remaining cleaning liquid in the liquid storage chamber 3. The detection data is transmitted to the control module 8, and the control module 8 compares the data with the preset alarm amount. When the remaining amount is lower than the alarm amount, the communication module 7 reminds the staff through SMS or app messages; when the ultrasonic distance sensor 6 is repaired, the squeezing rod 19 is pressed, and the squeezing rod 19 squeezes the elastic hook 18, so that the elastic hook 18 and the limit block 17 are matched. The end is tilted to one side and disengaged from the limit block 17, and the connecting block 10 is removed from the top of the detection chamber 2. Then the connecting rod 14 is squeezed to drive the block 12 to disengage from the positioning column 11, and the fixing frame 9 is separated from the connecting block 10, and the ultrasonic distance sensor 6 is removed; because the open-circuit methane analyzer body 1 will be installed at a high place through the detection support rod during use, the open-circuit methane analyzer body 1 will shake in windy weather, and the blocking plate 4 can divide the interior of the liquid storage chamber 3 into multiple spaces, destroying the propagation path of the wave, so that the wave gradually decays during the propagation process, thereby reducing the shaking of the cleaning liquid, reducing the fluctuation of the cleaning liquid plane caused by the shaking, and improving the detection accuracy of the detection chamber 2.
