Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to a low-power consumption gas monitoring device. Background Art

[0002] Gas monitoring devices are instruments used to detect the concentration of specific gases in the air. They are widely used in industrial safety, environmental protection, and indoor air quality monitoring. They can detect a variety of gases such as carbon monoxide, carbon dioxide, methane, and volatile organic compounds to ensure that the environment and human health are not affected by harmful gases.

[0003] An existing Chinese patent (publication number: CN214374607U) proposes a gas monitoring device, including a shell, a sensor and an air intake hood, wherein the shell is provided with an opening; the sensor is arranged in the opening and protrudes from the opening; the air intake hood is arranged at the opening for wrapping the sensor, and the air intake hood is provided with an air intake hole and a guide structure, the guide structure is arranged close to the air intake hole, and the gas passes through the air intake hole and enters the sensor along the guide structure.

[0004] The above technical solution is to provide an air inlet hole and a guide structure on the air inlet hood, so that the gas can enter through the air inlet hole and then enter the sensor along the guide structure, thereby greatly improving the efficiency of the sensor for gas entry. However, the gas flow rate in the above device is fixed. When the gas concentration is too high, the continuous input of high-concentration harmful substances may damage the detection device. Therefore, the existing equipment with a fixed flow rate is very easy to be damaged or its service life is greatly reduced in this case. When the gas flow rate is too small and the flow rate is too slow, the sample detection results will be inaccurate. Therefore, we propose a low-power gas monitoring device. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 and Figure 3 As shown, a low-power gas monitoring device includes a detector body 1, a power assembly 2 is arranged on the detector body 1, an air inlet is arranged on one side of the detector body 1 close to the power assembly 2, an adjustment assembly 3 is arranged at the bottom of the power assembly 2, the adjustment assembly 3 is located on the side of the inlet gas, the adjustment assembly 3 includes a first rack 31, a clamping block 36 is arranged on one side of the detector body 1 close to the first rack 31, a fixed frame 33 is clamped on the side of the clamping block 36 away from the detector body 1, a fan blade 35 is arranged in the fixed frame 33, and a rotating rod 34 is arranged on the side of the fan blade 35 close to the first rack 31 , the side of the rotating rod 34 away from the fan blade 35 is rotatably connected with the second rack 32, and the second rack 32 is meshed with the first rack 31. However, if the flow rate of the gas is fixed, in the occasion where the gas concentration needs to be quickly monitored, the fixed flow rate may not meet the demand for rapid response, resulting in reduced detection efficiency. Through the setting of the adjustment component 3, when the first rack 31 is raised or lowered, the second rack 32 is driven to be raised or lowered, and when the second rack 32 is raised or lowered, the rotating rod 34 is driven to rotate, and the rotating rod 34 drives the fan blade 35 to open and close, so that the flow rate of the gas can be adjusted;

[0031] Furthermore, if Figure 2 As shown: the power assembly 2 includes a fixed plate 21, a telescopic rod 22 is arranged at the bottom of the fixed plate 21, first slide rails 23 are arranged on both sides of the bottom of the fixed plate 21, a first slider 24 is slidably connected to the first slide rail 23, a second slide rail 25 is connected to the side of the first slider 24 away from the first slide rail 23, a second slider 26 is slidably connected to the second slide rail 25, a rotating shaft 27 is connected to the second slider 26, a fixed seat 28 is arranged on the rotating shaft 27, a support plate 6 is arranged on the side of the bottom of the fixed plate 21 close to the second slide rail 25, a motor 7 is arranged on the support plate 6, and a fixed shaft 8 is fixedly connected to the output end of the motor 7, by setting the power assembly 2, turning on the motor 7 drives the fixed shaft 8 to rotate, the fixed shaft 8 drives the fixed seat 28 to rotate, the fixed seat 28 drives the rotating shaft 27, and the rotating shaft 27 drives the second slider 26 to slide in the second slide rail 25, thereby driving the second slide rail 25 to rise and fall between the first slide rail 23, and finally driving the first rack 31 at the bottom to rise and fall;

[0032] The above schemes may also affect the detection results when there are too many impurities in the gas, such as Figure 1 As shown: an activated carbon plate 4 is arranged on one side of the detector body 1 close to the adjustment component 3, buckles 5 are arranged on both sides of the activated carbon plate 4, and the side of the buckle 5 away from the activated carbon plate 4 is snapped on the detector body 1. By arranging the activated carbon plate 4, impurities in the gas can be filtered out to improve the accuracy of detection. By arranging the buckle 5, the activated carbon plate 4 can be disassembled and cleaned to prevent clogging;

[0033] The above solution also has the problem that the arm between the fixed shaft 8 and the fixed seat 28 is too short, which will cause the lifting range of the first rack 31 to be too small, so that the fan blade 35 cannot be fully opened. Figure 2 As shown: the electric telescopic rod 29 is connected to the side of the fixed shaft 8 close to the second slider 26, the end of the electric telescopic rod 29 away from the fixed shaft 8 is fixedly connected to the fixed seat 28, the top of the first rack 31 is fixedly connected to the bottom of the second slide rail 25, and the length of the running track of the first rack 31 can be adjusted by setting the electric telescopic rod 29, so as to control the opening degree of the fan blade 35;

[0034] Furthermore, Figure 4 As shown: a heat sink 9 is arranged on the side of the detector body 1 away from the power assembly 2. There are five heat sinks 9 and they are distributed in a horizontal direction. By arranging the heat sink 9, the internal components of the detector can be cooled to prevent internal overheating and damage.

[0035] Working principle: Figure 1 - Figure 4 As shown, the gas enters the detector body 1 from the air inlet. However, if the gas flow rate is fixed, in situations where rapid monitoring of gas concentration is required, the fixed flow rate may not meet the demand for rapid response, resulting in reduced detection efficiency. By setting the power component 2, the motor 7 is turned on to drive the fixed shaft 8 to rotate, the fixed shaft 8 drives the fixed seat 28 to rotate, the fixed seat 28 drives the rotating shaft 27, and the rotating shaft 27 drives the second slider 26 to slide in the second slide rail 25, thereby driving the second slide rail 25 to rise and fall between the first slide rail 23, and finally driving the first rack 31 at the bottom to rise and fall. When the first rack 31 is raised and lowered, it will drive The second rack 32 is raised and lowered. When the second rack 32 is raised and lowered, the rotating rod 34 is driven to rotate, and the rotating rod 34 drives the fan blades 35 to open and close, so that the flow rate of the gas can be adjusted. By setting the activated carbon plate 4, impurities in the gas can be filtered out to improve the accuracy of detection. By setting the buckle 5, the activated carbon plate 4 can be disassembled and cleaned to prevent blockage. By setting the electric telescopic rod 29, the length of the running track of the first rack 31 can be adjusted, so as to control the amount of opening of the fan blades 35. By setting the heat sink 9, the internal components of the detector can be cooled to prevent internal overheating and damage.
