Description

Technical Field

[0001] This utility model belongs to the field of gas detection technology, specifically relating to a gas extraction and drainage comprehensive parameter measuring instrument. Background Technology

[0002] The gas drainage comprehensive parameter measuring instrument is mainly used for monitoring the drainage parameters of underground coal mine borehole gas pipelines. It is a precision instrument specifically designed for measuring 13 data points in underground coal mines, including methane, carbon monoxide, oxygen, hydrogen sulfide, carbon dioxide, pipeline negative pressure, pipeline temperature, operating flow rate, standard flow rate, methane flow rate, ambient air pressure, ambient temperature, and ambient humidity. It can also be used to measure the comprehensive gas parameters of the main and branch pipelines of the drainage pipeline.

[0003] The gas drainage comprehensive parameter measuring instrument has the advantages of high measurement accuracy and ease of use. The instrument transmits the measurement data to the computer wirelessly, and uses dedicated software to draw drainage parameter graphs and compile and print reports. Typically, a gas drainage integrated parameter analyzer includes a sampling head, connecting cables, and a main unit. The sampling head contains various sensors for detection, and the main unit contains various detection circuits for analyzing the sensor data. Due to the complex underground working conditions, a robust enclosure structure is used to protect the main unit. For example, the CJZ70 gas drainage integrated parameter analyzer has a display screen and operation buttons on the top surface of the main unit, which is flat to achieve waterproof and dustproof effects. This enclosure structure has a top cover, and there is a gap between the top cover and the top surface of the main unit, allowing the sampling head and connecting cables to be placed between the top surface and the top cover. However, placing the sampling head and connecting cables directly on the top surface will cause wear and tear on the top surface of the main unit over time. Moreover, the current enclosure structure and main unit are relatively bulky. Currently, the enclosure is usually moved by carrying it with handles or shoulder straps, which is time-consuming and laborious, and collisions are likely to occur during transportation, potentially damaging the equipment.

[0004] Therefore, we propose a comprehensive gas extraction parameter measuring instrument to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, this utility model proposes a gas extraction and drainage comprehensive parameter measuring instrument.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A gas extraction and release integrated parameter measuring instrument includes a housing with a gas exchange port on the top surface and a keypad on the front. Inside the housing are a control main board, an air pump, a reversing valve, a gas analysis chamber, a water tank, and a power supply. The control main board has a built-in Bluetooth module. The air pump's inlet and outlet are both connected to the reversing valve. A dryer is installed between the air pump's inlet and the reversing valve. The reversing valve, gas analysis chamber, and water tank are sequentially connected via pipes. Both the reversing valve and the water tank are connected to the gas exchange port via pipes. The reversing valve has a reversing lever that extends out of the housing. When the reversing lever is switched, the gas direction in the pipe changes. The water tank contains a moisture-absorbing material. The keypad, air pump, gas analysis chamber, and power supply are all electrically connected to the control main board.

[0008] In a further technical solution, the reversing valve is provided with an air inlet, an air outlet, a first switching port, and a second switching port. The air inlet and the air outlet are respectively connected to the air inlet and air outlet of the air pump through pipes. The first switching port is connected to the gas exchange port through a pipe, and the second switching port is connected to the gas analysis chamber through a pipe.

[0009] The air inlet and the first switching port of the reversing valve are connected, and the air outlet and the second switching port are connected. When the reversing lever is switched, the air inlet and the second switching port are connected, and the air outlet and the first switching port are connected.

[0010] In a further technical solution, a drain pipe extending out of the outer shell is connected to the water tank.

[0011] In a further technical solution, the reversing valve is equipped with a noise reduction device.

[0012] In a further technical solution, the front of the casing is provided with a display screen, which is electrically connected to the control motherboard.

[0013] In a further technical solution, a temperature and humidity sensor is also provided on the top surface of the housing, and the temperature and humidity sensor is electrically connected to the control motherboard.

[0015] In a further technical solution, the side of the housing is provided with a grip strap.

[0016] In a further technical solution, a dryer is provided on the pipe at one end of the air pump inlet.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model is small in size and easy to carry. Through highly integrated engineering design, the overall circuit power consumption is low, which can effectively meet the needs of long-term underground work.

[0019] 2. This utility model effectively reduces the moisture and humidity content in the extracted gas through the design of the dryer and the moisture-absorbing material in the water tank. This not only reduces the risk of moisture damage to the gas pump and extends its service life, but also ensures accurate gas measurement in the gas analysis chamber, providing a strong guarantee for the accurate measurement of gas extraction parameters.

[0020] 3. This utility model can switch the flow direction of the internal gas by using a reversing valve, which can facilitate the testing of different groups of gases. By discharging the original gas in the pipeline in the opposite direction, the influence of the original gas inside the measuring instrument on the test results can be effectively reduced, thereby improving the measurement accuracy and reliability of the measuring instrument.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] See Figures 1-3 (The pipes between the built-in components in the figure are not shown.) This utility model provides a gas extraction and release comprehensive parameter measuring instrument, including a shell 1. The top surface of the shell 1 is provided with a gas exchange port 2. The front of the shell 1 is provided with a keypad 3. The interior of the shell 1 is provided with a control main board 4, an air pump 5, a reversing valve 6, a gas analysis chamber 7, a water tank 8, and a power supply 9. The control main board 4 has a built-in Bluetooth module. The air inlet and outlet of the air pump 5 are both connected to the reversing valve 6. A dryer is provided between the air inlet of the air pump 5 and the reversing valve 6. The reversing valve 6, the gas analysis chamber 7, and the water tank 8 are connected in sequence by pipes. The reversing valve 6 and the water tank 8 are both connected to the gas exchange port 2 by pipes. The reversing valve 6 is provided with a reversing lever 10. The reversing lever 10 extends out of the shell 1. When the reversing lever 10 is switched, the gas direction in the pipe changes. The water tank 8 is provided with a moisture-absorbing material. The keypad 3, the air pump 5, the gas analysis chamber 7, and the power supply 9 are all electrically connected to the control main board 4.

[0030] This measuring instrument is compact and portable. Its internal components, such as the control mainboard 4, air pump 5, reversing valve 6, and gas analysis chamber 7, all utilize high-end products with advanced existing technology. Through highly integrated engineering design, the overall circuit consumes little power, effectively meeting the needs of long-term downhole operation. Its specific usage method is as follows:

[0031] First, when using this gas extractor, the instrument is operated via the keypad 3. The air pump 5 extracts gas from the surrounding environment, and the flow direction is controlled by the reversing valve 6. During extraction, the gas first passes through a dryer for drying. This step effectively reduces the moisture and humidity content in the extracted gas, thus reducing the risk of moisture damage to the air pump 5 and extending its service life. After drying, the gas then enters the gas analysis chamber 7 for analysis, providing accurate gas extraction parameters, which are recorded on the control board 4. Notably, this data can also be wirelessly transmitted via Bluetooth, facilitating real-time communication and data exchange with external devices, greatly improving data utilization efficiency and convenience. After analysis, the gas enters the water tank 8 and finally exits from the gas exchange port 2. To measure another set of gas data, the operator simply toggles the reversing lever 10, switching the flow direction of the internal gas in the reversing valve 6. By discharging the original gas in the pipeline in the opposite direction, the influence of the original gas inside the instrument on the test results is effectively reduced, improving the measurement accuracy and reliability of the instrument. During this process, gas enters the water tank 8 from the gas exchange port 2 and is dehumidified using the moisture-absorbing material inside the water tank 8. This design effectively reduces the probability of moisture entering the gas analysis chamber 7, while significantly reducing the risk of instrument malfunction. Finally, the gas passes through the air pump 5 and the reversing valve 6 again and is effectively discharged from the instrument, completing the entire gas extraction, analysis, and discharge process. Compared to traditional gas drainage comprehensive parameter analyzers, this instrument, with its compact design, high-end configuration, and reliable performance, provides strong support for the accurate measurement of gas drainage parameters.

[0032] In one specific implementation, see Figure 3 The reversing valve 6 is provided with an air inlet, an air outlet, a first switching port and a second switching port. The air inlet and the air outlet are respectively connected to the air inlet and air outlet of the air pump 5 through pipes. The first switching port is connected to the gas exchange port 2 through a pipe. The second switching port is connected to the gas analysis chamber 7 through a pipe.

[0033] The air inlet and the first switching port of the reversing valve 6 are connected, and the air outlet and the second switching port are connected. When switched by the reversing lever 10, the air inlet and the second switching port are connected, and the air outlet and the first switching port are connected.

[0034] The reversing valve 6 changes the gas flow direction through internal channel switching. When the reversing lever 10 is in the initial position, the inlet is connected to the first switching port and the outlet is connected to the second switching port, allowing the gas to flow along a preset path. When the reversing lever 10 is switched, the inlet is connected to the second switching port and the outlet is connected to the first switching port, thus changing the gas flow path. The switching function of the reversing valve 6 allows for rapid switching of gas flow direction without disassembling or reconnecting pipelines, effectively improving measurement efficiency. This enables the measuring instrument to operate more efficiently and stably in complex environments such as underground coal mines, providing strong technical support for safe coal mine production.

[0035] In one specific implementation, see Figure 2 and Figure 3 The water tank 8 is connected to a drain pipe 11 that extends out of the outer shell 1.

[0036] The drain pipe 11 is installed on the water tank 8 and extends out of the outer casing 1. When water enters the instrument during the extraction process, it can automatically discharge the water that exceeds the water level when the water level in the water tank 8 reaches the position of the drain pipe 11. This ensures that the instrument can maintain stable operation in humid or watery environments, effectively improves the reliability of the instrument, and greatly reduces the risk of failure caused by water accumulation.

[0037] In one specific implementation, see Figure 3 The reversing valve 6 is equipped with a noise reduction device 12.

[0038] The noise reducer 12 can reduce the noise generated by the air pump 5 during operation, making the measuring instrument quieter during operation, reducing the impact on operators and the environment, and effectively improving the overall user comfort and satisfaction of the measuring instrument.

[0039] In one specific implementation, see Figure 1 The front of the outer casing 1 is provided with a display screen 16, which is electrically connected to the control motherboard 4.

[0040] The display screen 16 can show the measurement data of the instrument, such as key parameters like methane concentration, carbon monoxide concentration, carbon dioxide concentration, pressure, and flow rate, making it easy for operators to obtain the required information intuitively and quickly, thus improving work efficiency.

[0041] In one specific implementation, see Figures 1-3 The top surface of the outer casing 1 is also provided with a temperature and humidity sensor 13, which is electrically connected to the control motherboard 4.

[0042] Through the temperature and humidity sensor 13, the measuring instrument can accurately sense changes in the temperature and humidity of the surrounding environment in real time and quickly transmit this data to the control motherboard 4. Subsequently, this data is displayed on the screen 16, allowing operators to clearly understand the temperature and humidity conditions of the environment in which the measuring instrument is located. This provides important environmental parameter references for the normal operation of the measuring instrument and also helps operators make corresponding adjustments or decisions in a timely manner according to environmental changes, ensuring that the measuring instrument maintains its optimal working condition under various environmental conditions.

[0043] In one specific implementation, see Figure 3 The power source 9 is a storage battery, and a charging board 14 is provided inside the housing 1. The charging board 14 is connected to the storage battery wires, and the charging port is located at the bottom of the housing 1.

[0044] The instrument uses a rechargeable battery as its power source 9, which supports charging and provides a long-lasting and stable power supply. This ensures that the instrument can continue to operate even when working for a long time or when an external power source 9 is unavailable, thus meeting the measurement needs in complex environments such as underground coal mines.

[0045] In one specific implementation, see Figures 1-3 The outer casing 1 has a grip strap 15 on its side.

[0046] By adding a grip strap 15 to the side of the housing 1, it is easier to hold the measuring instrument during use, which not only makes it easier to use, but also reduces the risk of the measuring instrument falling due to slipping or accidental collision.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
