Description

Technical Field

[0001] This utility model belongs to the field of air detection technology, and in particular relates to a portable environmental multi-parameter detection device. Background Technology

[0002] In mining operations, real-time and accurate monitoring of ambient air quality parameters is crucial for ensuring the safety of miners and production. Mine air typically contains large amounts of dust, as well as harmful gases such as carbon monoxide and methane; therefore, comprehensive monitoring of air quality using multi-parameter environmental monitoring equipment is necessary.

[0003] Traditional environmental multi-parameter detectors are bulky. When monitoring mine air quality, these devices typically use filter plates to filter the incoming air to prevent dust and other particulate matter from entering the equipment and damaging the sensors, thus ensuring accurate results. However, due to the unique characteristics of the mine environment, the air contains extremely high levels of dust, making the filter plates prone to clogging. Once clogged, this not only hinders airflow and affects the equipment's ability to collect air samples, but also reduces sensitivity and accuracy. To maintain normal operation, frequent filter replacements are necessary. However, since testing is conducted inside the mine, personnel cannot carry multiple filter plates, making replacement inconvenient. Furthermore, the equipment is shut down during replacement, interrupting continuous monitoring of mine air quality and hindering timely assessment and early warning of mine safety conditions, posing a significant safety hazard. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a portable environmental multi-parameter detection device, which solves the problem that existing equipment requires frequent replacement of filter plates, resulting in low detection efficiency.

[0005] This utility model is implemented as follows: a portable environmental multi-parameter detection device includes a housing, an air detector disposed within the housing, a pump installed within the housing, an air duct disposed on the housing, and multiple filter plates disposed within the housing, and further includes:

[0006] A rotating cavity located inside the housing for the movement of multiple filter plates;

[0007] A mounting bracket is rotatably mounted inside the housing for mounting and rotating multiple filter plates. The multiple filter plates are rotatably mounted on the mounting bracket in a ring at equal angles.

[0008] An airflow chamber, located inside the housing, is used to guide the gas detected by the air detector outwards, and the filter plate is cleaned when the airflow chamber is discharged.

[0009] As a preferred embodiment of this utility model, the air duct includes an air inlet pipe and an air outlet pipe. The air inlet pipe passes through the bottom of the housing and rotates through the housing, communicating with the pump installed inside the housing. When the gas passes through the through-hole, the filter plate filters the gas.

[0010] In a preferred embodiment of this invention, the airflow cavity is interconnected with the gas detected by the air detector, and the exhaust pipe is interconnected with the exhaust end of the airflow cavity. When the airflow is discharged through the airflow cavity, the gas cleans the filter plate. A separation component is provided in the rotating cavity to isolate the intake pipe and the exhaust pipe.

[0011] As a preferred embodiment of this utility model, the separation component includes a sealing plate installed in the rotating cavity, the mounting bracket being rotatably disposed within the sealing plate, and the air inlet pipe and the exhaust pipe being respectively disposed on both sides of the sealing plate, and two pairs of flexible plates for sealing the sealing plate being installed on the sealing plate.

[0012] As a preferred embodiment of this invention, the upper part of the airflow cavity is provided with multiple air holes for cleaning the filter plate as it passes through.

[0013] As a preferred embodiment of this invention, the rotating cavity is provided with multiple cloth strips, and the cloth strips swing through the airflow discharged from the air holes, and clean the filter plate during the swing.

[0014] As a preferred embodiment of the present invention, a drive turbine is installed at one end of the mounting bracket, and the drive turbine drives the mounting bracket to rotate through the airflow entering the airflow cavity.

[0016] As a preferred embodiment of this invention, a telescopic rod is also installed on the outer side of the housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a pump within the device to adsorb airflow, ensuring a sufficient flow of air entering the air detector. The air is filtered through a filter plate, preventing the presence of impurities that could affect the accuracy of gas detection. After detection, the discharged gas acts on the filter plate, effectively cleaning its surface and preventing clogging that could hinder gas discharge. Each operation utilizes the pump's suction and discharge mechanisms, resulting in fewer internal components, making the device more portable and improving ease of use while reducing energy consumption.

[0026] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, the portable environmental multi-parameter detection device provided in this embodiment of the present invention includes a housing 1, an air detector 2 disposed within the housing 1, a pump 3 installed within the housing 1, an air duct 4 disposed on the housing 1, and multiple filter plates 5 disposed within the housing 1, and further includes:

[0029] A rotating cavity 6 is formed inside the housing 1 for the movement of multiple filter plates 5;

[0030] A mounting frame 7 is rotatably arranged inside the housing 1 for mounting and rotating multiple filter plates 5. The multiple filter plates 5 are movably arranged in a ring at equal angles on the mounting frame 7.

[0031] An airflow chamber 10 is formed inside the housing 1 to guide the gas detected by the air detector 2 out, and the airflow chamber 10 cleans the filter plate 5 when it is discharged.

[0032] As a preferred embodiment of this utility model, the air duct 4 includes an air inlet pipe and an air outlet pipe. The air inlet pipe passes through the bottom of the housing 1 and the rotating cavity 6, and is interconnected with the pump 3 installed in the housing 1. When the gas passes through the through position, the filter plate 5 filters the gas. During detection, the gas can be fully filtered through the filter plate 5 to prevent dust impurities in the gas from entering the air detector 2 and causing damage to the air detector 2.

[0033] In a preferred embodiment of this invention, the airflow chamber 10 is interconnected with the gas detected by the air detector 2, and the exhaust pipe is interconnected with the exhaust end of the airflow chamber 10. When the airflow is discharged through the airflow chamber 10, the gas cleans the filter plate 5. A separation component is provided in the rotating chamber 6 to isolate the inlet pipe and the exhaust pipe, so that the equipment can effectively clean the filter plate 5 while discharging the gas, further ensuring the cleanliness of the filter plate 5.

[0034] As a preferred embodiment of this utility model, the separation component includes a sealing plate 8 installed in the rotating cavity 6, a mounting bracket 7 rotatably disposed in the sealing plate 8, and an air inlet pipe and an exhaust pipe respectively disposed on both sides of the sealing plate 8. Two pairs of flexible plates 9 for sealing the sealing plate 8 are installed on the sealing plate 8, effectively dividing the rotating cavity 6 into two chambers to prevent gas crossflow.

[0035] As a preferred embodiment of this utility model, the upper part of the airflow cavity 10 is provided with a plurality of air holes 11 for cleaning the filter plate 5 as it passes through, which can fully and evenly disperse the gas so as to fully clean the filter plate 5 and thus ensure the cleanliness of the filter plate 5.

[0036] As a preferred embodiment of this utility model, a plurality of cloth strips 14 are provided in the rotating cavity 6, and the cloth strips 14 swing through the airflow discharged from the air hole 11, and clean the filter plate 5 when swinging. Through the swinging of the cloth strips 14, the filter plate can be effectively swept, thereby accelerating the separation of dust from the filter plate 5, so that it can be quickly discharged through the exhaust pipe.

[0037] As a preferred embodiment of this utility model, a drive turbine 12 is installed at one end of the mounting frame 7, and the drive turbine 12 drives the mounting frame 7 to rotate through the airflow entering the airflow chamber 10, so that the gas can drive the mounting frame 7 to rotate, thereby realizing the replacement of the filter plate 5, while reducing the installation of parts in the housing 1, making it more convenient to carry.

[0038] As a preferred embodiment of this invention, a frustum-shaped air collector shroud 13 is installed inside the airflow cavity 10, and the air collector shroud 13 is located on the upper side of the drive turbine 12, which can effectively gather the gas, making the exhaust airflow larger and easier to drive the drive turbine 12 to rotate the mounting frame 7.

[0039] As a preferred embodiment of this utility model, a telescopic rod 15 is also installed on the outside of the housing 1, which facilitates the adjustment of the housing 1 to different heights, thereby realizing gas detection at different heights and further ensuring the detection accuracy of the equipment.

[0040] The working principle of this utility model:

[0041] refer to Figure 1 and 2 The length of the telescopic rod 15 can be changed by pulling it, so that the housing 1 can be moved to different heights, thereby enabling the detection of gas parameters at different heights and ensuring the detection accuracy of the equipment.

[0042] When housing 1 moves to different heights, reference Figure 3 and Figure 4 Because the sealing plate 8 divides the rotating cavity 6 and the flexible plate 9 seals the sealing plate 8, when the pump 3 is working, the suction generated by the pump 3 draws gas into the left half of the rotating cavity 6 through the air inlet pipe. The gas then passes through the filter plate 5, allowing it to be filtered. The filtered gas then enters the pump 3, which discharges the gas into the air detector 2. The air detector 2 then detects the gas and analyzes the data using external equipment. After the air detector 2 has finished detecting the gas, it is discharged from the air detector 2. Figure 5 The gas flow chamber 10 in the middle is discharged downwards, and at the same time the gas acts on the drive turbine 12, thereby causing the drive turbine 12 to rotate. When the drive turbine 12 rotates, the reference... Figure 3 and Figure 4 The drive turbine 12 drives the mounting bracket 7 to rotate. At this time, the mounting bracket 7 rotates counterclockwise, making it opposite to the direction of the incoming airflow. This ensures that the filter plate 5 can fully filter the incoming airflow. The rotation of the mounting bracket 7 can change the filter plate 5 at the air inlet pipe, so that the airflow can always be filtered through the clean filter plate 5 when it enters the pump 3. The filter plate 5 rotated to the air hole 11 is subjected to air discharged from the airflow chamber 10. The air passes through the air hole 11 and acts on the filter plate 5. At the same time, the shaking of the cloth strip 14 can effectively clean the impurities on the surface of the filter plate 5. The cleaned air is discharged through the exhaust pipe, and the cleaning work is repeated.

[0043] Each time the filter plate 5 does not pass through the flexible plate 9, the two flexible plates 9 are in a vertical state, which can effectively seal the sealing plate 8 and prevent gas crossflow. When the filter plate 5 passes through the flexible plate 9, the flexible plate 9 deforms. When the filter plate 5 has completely passed through, it resets again, realizing the resealing of the sealing plate 8.

[0044] This invention utilizes the pump 3 within the device to adsorb airflow, ensuring a sufficient flow of air entering the air detector 2. The airflow is filtered by the filter plate 5, preventing the presence of numerous impurities that could affect the accuracy of gas detection. After detection, the discharged gas acts on the filter plate 5, effectively cleaning its surface and preventing blockage that could hinder gas discharge. Each operation of the device utilizes the pump 3 for both intake and exhaust, resulting in fewer internal components, easier portability, improved usability, and reduced energy consumption.
