Description

Technical Field

[0001] This utility model relates to the field of mine environmental monitoring technology, specifically to a mine environmental monitoring device that is easy to clean. Background Technology

[0002] Mining processes generate large amounts of gases containing solid impurities, which not only pollute the surrounding air environment but also affect the health of workers and nearby residents. Therefore, it is necessary to use mine environmental monitoring equipment to monitor the composition and concentration of harmful gases in the air around the mine in real time. Secondly, since the gases around the mine contain a lot of dust, which easily adheres to the mine environmental monitoring equipment, it is crucial to design mine environmental monitoring equipment that is easy to clean.

[0003] However, existing mine environmental monitoring equipment still has many shortcomings in its cleaning function design. While many devices are equipped with fixed filter plates to intercept solid impurities in the gas, the fixed structure of these plates makes them difficult to clean or replace in a timely manner. Over time, they become clogged with dust particles, obstructing gas flow and affecting the sampling efficiency and detection accuracy of the probes. Furthermore, during the cleaning process, most devices rely solely on fixed nozzles for rinsing, limiting water pressure and coverage, resulting in uneven cleaning and difficulty in thoroughly removing dust from the equipment surface, thus affecting the cleaning effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The exhaust mechanism includes an expansion tube located at the bottom of the gas detector, with an air pump connected to the bottom of the expansion tube, and an exhaust pipe penetrating the monitoring box located on the outside of the bottom of the air pump.

[0007] Furthermore, to facilitate the rapid assembly and disassembly of the filter plates, the filter plates can be quickly removed through the cooperation of springs and snap-fit ​​blocks.

[0008] Furthermore, to achieve uniform cleaning of the equipment's outer surface, the nozzles evenly arranged on the pipe frame can continuously rotate and clean under the combined action of the motor and the rotating block. This achieves comprehensive and uniform cleaning of the outer surface of the testing box. The rotating cleaning mechanism includes a pipe frame located on the outside of the testing box, with several nozzles connected to the inside of the pipe frame to cooperate with the testing box. A water tank is connected to the top of the pipe frame. A first connecting plate is connected to the top of the water tank, and a rotating block is located at the top of the first connecting plate.

A rotating column runs through the middle of the rotating block, with a motor at one end connected to the support frame. The motor and the rotating column are connected via a first rotating rod. A connecting column is located at the other end of the rotating column, with a second fixed plate at one end connected to the support frame. The connecting column and the rotating column are connected via a second rotating rod. The rotating block is connected to the first fixed plate via a bearing. The second fixed plate is connected to the connecting column via a bearing. The support frame is connected to the second connecting plate via a bearing.

The exhaust mechanism 7 includes an expansion pipe 701 disposed at the bottom of the gas detector 6, an air pump 702 connected to the bottom of the expansion pipe 701, and an exhaust pipe 703 disposed on the outside of the bottom of the air pump 702, penetrating the monitoring box 3.

[0018] In one embodiment, the aforementioned snap-fit ​​mechanism 5 includes: a placement slot 501 symmetrically arranged on one side of the detection box 3; a snap-fit ​​frame 502 disposed inside the placement slot 501; a spring 503 symmetrically disposed inside the snap-fit ​​frame 502; a contact ball 504 symmetrically disposed in the middle of the snap-fit ​​frame 502 and connected to the spring 503; and a snap-fit ​​block 505 disposed between the two sets of contact balls 504 and cooperating with the two sets of contact balls 504, and connected to the filter plate 4; the snap-fit ​​frame 502 has a concave cross-section; and can quickly remove the filter plate 4 under the cooperative action of the spring 503 and the snap-fit ​​block 505, facilitating the cleaning and maintenance of the filter plate 4, ensuring the filtration effect and smooth gas flow of the equipment, and improving the convenience and efficiency of equipment maintenance in high dust environments in mines.

[0019] In one embodiment, the rotating cleaning mechanism 8 includes a pipe frame 801 disposed outside the detection box 3. A plurality of nozzles 802 cooperating with the detection box 3 are connected to the inner side of the pipe frame 801. A water tank 803 is connected to the top of the pipe frame 801. A first connecting plate 804 is connected to the top of the water tank 803. A rotating block 805 is disposed at the top of the first connecting plate 804. First fixing plates 806 are disposed at both ends of the rotating block 805. Fixing columns 807 are passed through both ends of the first fixing plates 806. Second connecting plates 808 connected to the support frame 2 are disposed at the top of the plurality of fixing columns 807. A rotating column 809 is passed through the middle of the rotating block 805. A motor 810 connected to the support frame 2 is disposed at one end of the rotating column 809. The motor 810 is connected to the rotating column 809 via a first rotating rod 811; a connecting column 812 is provided at the other end of the rotating column 809, and a second fixing plate 813 connected to the support frame 2 is provided at one end of the connecting column 812; the connecting column 812 and the rotating column 809 are connected via a second rotating rod 814; the rotating block 805 is connected to the first fixing plate 806 via a bearing; the second fixing plate 813 is connected to the connecting column 812 via a bearing; the support frame 2 is connected to the second connecting plate 808 via a bearing; by rotating the cleaning mechanism 8, under the combined action of the rotation of the motor 810 and the rotating block 805, the nozzles 802 evenly arranged on the pipe rack can continuously rotate and clean, thereby achieving all-round and uniform cleaning of the outer surface of the detection box 3.

[0020] Furthermore, it should be noted that the water tank 803 is equipped with a submersible pump. This pump pumps water from inside the tank 803 to the nozzle 802 via the pipe frame 801, enabling the spraying and washing of the outer surface of the inspection box 3. The top of the water tank 803 has a perforated water inlet connected to an external water pipe. The tank 803 also contains a radar-based level sensor to monitor the water level and ensure timely replenishment. This level sensor uses radio wave transmission and reception to accurately measure the water level, providing stable and reliable results even in harsh environments. Specifically, the level sensor monitors the water level in the tank 803 and transmits the monitored signal to an external controller. When the external controller detects that the water level is below a preset minimum level, it activates a solenoid valve connected to the external water pipe, initiating the water filling process until the water level monitored by the level sensor rises back to the preset safe level.

[0021] In addition, it should be noted that the top of the above-mentioned detection box 3 has a hollow structure to ensure that the gas in the mining environment can smoothly enter the box, thereby providing a stable airflow source for the gas detector 6 and ensuring the continuity and accuracy of the detection process.

[0022] Furthermore, it should be noted that the aforementioned gas detector 6 is used to detect the composition and concentration of gases in the mining environment. The gas detector 6 consists of an electrochemical sensor, a catalytic combustion sensor, a signal processor, and a microprocessor. It is used to identify and measure the concentrations of methane, carbon monoxide, and hydrogen sulfide gases in the mining environment. The electrochemical sensor and the catalytic combustion sensor are used to collect methane, carbon monoxide, and hydrogen sulfide gas signals. The signal processor includes an amplifier and an analog-to-digital converter. The signal processor is responsible for filtering and amplifying the weak gas signals collected by the sensors, and analyzing the gas concentration values ​​through the microprocessor. It is also connected to a controller and a display for real-time presentation of the detection data.

[0023] Furthermore, it should be noted that the aforementioned gas extraction mechanism 7 drives gas flow, ensuring that gas can stably enter the detector, thereby achieving efficient and accurate monitoring of gas composition in the mining environment. Gas from the mining environment is drawn into the detection chamber 3 by the air pump 702. After initial filtration of large particulate impurities by the filter plate 4, the clean gas enters the gas detector 6. The gas detector 6 generates corresponding electrical signals based on the gas composition. After conversion and analysis by the signal processor, information such as gas concentration is connected externally to a controller and display for monitoring, thereby achieving accurate detection and monitoring of harmful gases in the mining environment.

[0024] Furthermore, it should be noted that the aforementioned air pump 702 mainly consists of a motor, impeller, pump body, and inlet / outlet ports. The working principle of the air pump 702 is that the motor drives the impeller to rotate at high speed, creating a negative pressure inside the pump body. This draws in gas from the mining environment through the inlet and discharges the collected gas through the exhaust pipe 703 at the bottom. Simultaneously, during the detection process, the expansion pipe 701 ensures stable gas intake, thereby guaranteeing that the gas detector 6 can accurately and continuously complete gas sampling and detection. In this process, the gas enters the gas detector 6 smoothly through the expansion pipe 701, providing a stable airflow and ensuring the accuracy and continuity of the detection results.

[0025] In addition, it should be noted that the above-mentioned air extraction mechanism 7, gas detector 6 and rotating cleaning mechanism 8 are electrically connected to the external controller PLC. The controller is existing technology and will not be elaborated on here.

[0026] Furthermore, it should be noted that tripod 1 consists of three legs, a connecting rod assembly, bolts, and a central connector. The bottom of the legs is equipped with stable pads to increase friction with the ground, ensuring stability on various terrains. Its working principle involves adjusting the length of each leg through the cooperation of the connecting rod assembly and bolts, allowing the tripod to remain level on uneven ground. This tripod 1 is existing technology and will not be elaborated upon further here.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, the mine environmental monitoring equipment is placed at the location to be monitored using a tripod 1. Then, the external controller activates the air extraction mechanism 7 and gas detector 6 within the monitoring chamber 3, which in turn starts the air pump 702. The air pump 702 draws mine air into the monitoring chamber 3 through the expansion pipe 701. After passing through a filter plate 4 to remove large particles, the gas enters the gas detector 6, where the sensor detects the gas composition. The signal processor and microprocessor analyze and process the collected gas signals, and the results are displayed in real-time on an external monitor. The external controller also periodically cleans the outer surface of the mine environmental monitoring equipment. The motor 810 and water pump are started by an external controller, which drives the rotating column 809 and rotating block 805 to rotate together under the connection of the first rotating rod 811. With the cooperation of the second rotating rod 814 and the limiting action of the second fixed plate 813, the second connecting plate 808 rotates, which in turn drives the pipe frame 801 connected to the first connecting plate 804 to rotate. This causes several nozzles 802 to rotate around the detection box 3. During the rotation, the nozzles 802, which are evenly arranged on the pipe frame, continuously spray the cleaning liquid in the water tank 803, thereby cleaning the outer surface of the detection box 3 in an all-round and uniform manner. The filter plate 4 is periodically removed from the inspection box 3 by the operator for cleaning. During removal, the locking block 505 presses against the ball 504, causing the ball 504 to compress the spring, thereby disengaging the locking block 505 from its locking position. This allows for the quick removal of the filter plate 4, removing dust and impurities adhering to its surface, ensuring filtration efficiency and smooth gas flow, and improving the convenience and efficiency of equipment maintenance in high-dust mining environments. After cleaning, quick disassembly and assembly are achieved through the locking mechanism 5. When the filter plate 4, along with the locking block 505, is inserted into the locking bracket 502, the ball 504 is compressed inward, compressing the spring 503. When the locking block moves to the appropriate position, the spring 503 returns to its original position, pushing the ball 504 into the locking block 505, thus securing the filter plate 4 firmly.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the support frame 2, detection box 3, filter plate 4, snap-fit ​​mechanism 5, gas detector 6, air extraction mechanism 7, and rotating cleaning mechanism 8, not only can gases containing solid impurities in the mining environment be filtered and detected, but the filter plate 4 can also be quickly disassembled and replaced, avoiding the impact on gas collection efficiency and detection accuracy due to filter plate blockage, thus significantly improving the equipment's maintenance convenience and work efficiency. Meanwhile, when cleaning the outer surface of the equipment, it can achieve all-round and uniform cleaning, effectively removing attached dust, improving the cleaning effect and the service life of the equipment; through the snap-fit ​​mechanism 5, the filter plate 4 can be quickly removed under the action of the spring 503 and the snap-fit ​​block 505, which facilitates the cleaning and maintenance of the filter plate 4, ensuring the filtration effect of the equipment and smooth gas flow, and improving the convenience and efficiency of equipment maintenance in the high dust environment of the mine; through the rotation cleaning mechanism 8, under the rotation action of the motor 810 and the rotating block 805, the nozzles 802 evenly arranged on the pipe frame can continuously rotate and clean, thereby achieving all-round and uniform cleaning of the outer surface of the detection box 3.
