Description

Technical Field

[0001] The invention relates to the field of dust concentration detection, and in particular to a mine segmented dust concentration detection device. Background Art

[0002] A mine refers to a place where natural resources such as minerals, rocks, gems, coal, oil, natural gas and groundwater are extracted from the earth's crust. Mining operations usually involve multiple links such as exploration, mining, processing and transportation. It is an important foundation for industrial and economic development. Dust concentration detection is the process of evaluating the content of suspended particulate matter in the air in a working environment or a specific area. Especially in industries that are prone to generate a lot of dust, such as mines, construction sites, manufacturing, and textiles, regular dust concentration detection is necessary.

[0003] The existing method is to install a detection sensor on a robot, and then use the robot to drive the detection sensor into the mine to detect the dust concentration, and then use the detection sensor to continuously detect the dust. During the detection, the robot needs to move to detect dust at different positions. During the detection process, the dust in the mine will cover the detection sensor, resulting in unstable detection results, thereby affecting the accuracy of the detection results.

[0004] Therefore, it is necessary to design a mine segmented dust concentration detection device that can detect the dust concentration at different positions and clean the lens at the same time to prevent dust from covering the lens, improve the accuracy of the dust concentration detection results, and sample the dust at different positions. Summary of the invention

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the detection and cleaning mechanism 4 includes an electric push rod 41, a fixing member 42, a connecting member 43, a lens 44, a fixing frame 45, a motor 46, a rotating brush 47 and a pressure rod 48. The electric push rod 41 is connected to the upper side of the shell 1, the telescopic end of the electric push rod 41 is connected to the fixing member 42, a laser emitter is arranged inside the fixing member 42, the upper part of the fixing member 42 is connected to the connecting member 43, the fixing member 42 and the connecting member 43 are both connected to the lens 44, the fixing member 42 is connected to the fixing frame 45 at the left front part, the fixing frame 45 is connected to the motor 46, the output shaft of the motor 46 is connected to the rotating brush 47, the lenses 44 are in contact with the rotating brush 47, the lower front side of the rotating brush 47 is connected to the pressure rod 48, and the front part of the pressure rod 48 is an inclined surface.

[0031] like Figure 1 , Figure 5 and Figure 6As shown, the sampling mechanism 5 includes a first fixed plate 51, a fixed rod 52, a rotating frame 53, a threaded column 54, a sleeve 55, a guide rod 56, a first spring 57, a sampling bottle 58, a sealing plate 59 and a second spring 510. The telescopic end of the electric push rod 41 is connected to the first fixed plate 51, the first fixed plate 51 is located at the lower side of the fixing member 42, the upper side of the front of the first fixed plate 51 is connected to the fixed rod 52, the middle of the fixed rod 52 is rotatably connected to the threaded column 54, and the upper part of the threaded column 54 is connected to the rotating The frame 53, the left and right parts of the first fixed plate 51 are connected with guide rods 56, the guide rods 56 are slidably connected with a sleeve 55, the sleeve 55 is slidably connected with the threaded column 54, the sleeve 55 is in contact with the pressure rod 48, and a first spring 57 is connected between the sleeve 55 and the first fixed plate 51.

[0032] When it is necessary to detect the concentration of dust in the mine, the device can be used and brought to the place where the dust concentration in the mine needs to be detected. Then the device is moved into the mine, and then the electric push rod 41 is started. The connecting piece 43 is driven to move by the electric push rod 41, and then the connecting piece 43 and the lens 44 are driven to move. Then the laser emitter in the connecting piece 43 emits laser, and the laser beam is converged by the lens 44 to detect the dust concentration. Then the device is moved to detect the dust concentration at different positions in the mine. The detected data will be recorded on the display screen 2. When the dust concentration exceeds the standard during the detection process, the alarm light 3 lights up to prompt. During the detection process, the motor 46 on the fixing frame 45 is started, and the rotating brush 47 is driven to rotate by the motor 46, so that the rotating brush 47 contacts with the connecting piece 43 and the lens 44 on the fixing piece 42, so as to clean the lens 44 to prevent dust from covering the lens 44, thereby improving the accuracy of the dust concentration detection result.

The dust in the dust collecting bottle is collected, so that the dust in different positions can be sampled, which is convenient for the later detection of the substances in the dust. After the collection bottle is switched, the first spring 57 rebounds, and the sleeve 55 moves and resets. After the sampling is completed, the next collection bottle is switched to the air intake position, the second spring 510 rebounds, and the sealing plate 59 moves and resets. After the detection is completed, the motor 46 is turned off, and the electric push rod 41 is started to operate in the reverse direction, thereby driving the fixing part 42 and the first fixing plate 51 to move and reset, and then the electric push rod 41 is turned off, and the device can be moved out of the mine.

[0033] like Figure 1 and Figure 6 As shown, it also includes an air intake mechanism 6, which includes a second fixed plate 61, an air intake pipe 62, a valve 63 and a torsion spring 64.

[0034] When the motor 46 drives the rotating brush 47 and the pressure rod 48 to rotate, the rotating brush 47 contacts the valve 63, causing the valve 63 to rotate and open, and the torsion spring 64 is deformed, allowing the gas to enter the sampling bottle 58 from the air inlet pipe 62. When the rotating brush 47 is disengaged from the valve 63, the torsion spring 64 rotates to restore, and the valve 63 rotates to reset and close, thereby automatically opening and closing the valve 63, making it easier for the gas to enter the sampling bottle 58, thereby improving the convenience of using the device.

[0036] Before the device enters the mine, the shell 1 is placed on the mounting plate 75, and then the tracked vehicle 71 is started. The tracked vehicle 71 drives the bottom plate 72 and the headlight 73 to move, thereby driving the shell 1 to move, so that the device enters the mine, moves the device to different positions, and then illuminates the device through the headlight 73. During the movement, the device is damped under the action of the damping rod 74 and the third spring 76, so that the device can be moved while being damped and illuminated, thereby reducing the vibration and impact of the device during the movement, protecting the device, and extending the service life of the device. After the inspection is completed, the tracked vehicle 71 is started to move out of the mine, and then the tracked vehicle 71 can be closed.
