TECHNICAL FIELD
[0001] The present application belongs to the technical field of coal mine safety, and particularly relates to a coal mine underground safety corner detection device. BACKGROUND
[0002] A coal mine is a region where human beings mine coal resources in a coal-rich mining area, and is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the ground surface, a tunnel is generally excavated underground to mine coal, which is an underground coal mine. A mine shaft is a general term for shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, the inclined shaft, vertical shaft and adit in the underground development of the mine are also called mine shafts. The determination of the size of the mine field, the mine production capacity and the service life of each mine shaft is one of the key problems that must be solved in the design of the mine shaft.
[0003] In the field of coal mine safety production, safety management is always the top priority and is directly related to the safety of miners and the efficient operation of the mine. For the safety detection of the mine, coal mine wind detection is the most important link. According to the safety regulations of the coal mine, wind detection needs to be performed once every ten days to ensure the safety of underground ventilation.
[0004] For the wind detection of the underground mine, there are two detection methods. One is to use a handheld mechanical ventilation detector to perform interval detection and take an average value in the underground mine. The other is to use an ultrasonic wind detection system to solve the problems of time-consuming and labor-intensive, poor real-time performance and poor accuracy of traditional manual wind detection. However, since the principle of the ultrasonic wind detection system is to calculate the wind speed and direction based on the time difference between multiple probes, if personnel enter the measurement area, the ultrasonic wave path may be directly blocked, resulting in signal loss or abnormality, false signals and inaccurate data.

Since the lifting block is screwed with the adjusting screw rod 13 and the lifting block is connected with the guide rail, the adjusting screw rod 13 drives the lifting block to lift. At the same time, the rotating disc 11 can drive the screw rod support 9 to rotate as a whole, and the screw rod support 9 drives the ultrasonic wind speed sensor probe 16 to horizontally rotate. The ultrasonic wind speed sensor probe 16 can lift and horizontally rotate, so that the wind measurement work can be more comprehensive.
[0028] The horizontal plate upper end face of the screw rod support 9 upper end is fixedly provided with a retention bin mounting plate 18 by bolts, the sensor retention bin 17 is fixedly provided on the retention bin mounting plate 18, the lower end of the sensor retention bin 17 is provided with an access, and the access of the sensor retention bin 17 lower end is located above the ultrasonic wind speed sensor probe 16.

The rotating shafts on the two protective cover plates 19 are rotationally connected with both sides of the access of the sensor retention bin 17 lower end, and the connecting positions of the rotating shafts and the access are provided with torsion springs, so that when the protective cover plates 19 are not subjected to external force, the protective cover plates 19 are in a horizontal state under the action of the torsion springs, and the two horizontal protective cover plates 19 close the access.
[0029] A cylindrical rotating chuck 23 is fixedly provided at one end of each of the two rotating shafts, the rotating chuck 23 is coaxially provided with the rotating shaft, and a circle of chuck holes 24 is arranged on the side end face of the rotating chuck 23 away from the rotating shaft. A sliding seat is provided at one side of each of the two rotating chucks 23 away from the rotating shaft, the sliding seat is fixedly provided at the inside bottom face of the sensor retention bin 17, a displacement cross rod 25 is slidingly inserted into each of the two sliding seats, and the displacement cross rod 25 slides along the axis of the rotating shaft.

The mutually distant ends of the two connecting rods 22 are respectively inserted into the interiors of the two anti-disengagement sleeve rods 26.
[0030] When the ultrasonic wind speed sensor probe 16 is in normal working state, the ultrasonic wind speed sensor probe 16 is located outside the sensor retention bin 17, at this time the two protective cover plates 19 at the entrance of the lower end of the sensor retention bin 17 are in a horizontal closed state, the actuating branch plate 20 is also in a horizontal state, and the positioning insert strip 27 is in a disengaged state with the chuck hole 24 of the rotating chuck 23. When the ultrasonic wind speed sensor probe 16 moves upward to the inside of the sensor retention bin 17, the ultrasonic wind speed sensor probe 16 first contacts the two protective cover plates 19, which are lifted upward, and the protective cover plates 19 drive the rotating shaft to rotate, and the torsional spring at the rotating shaft is compressed. As the ultrasonic wind speed sensor probe 16 continues to rise, the ultrasonic wind speed sensor probe 16 contacts the end of the actuating branch plate 20 away from the connecting branch rod 22, which is lifted upward, the connecting branch rod 22 rotates downward around the branch plate rotating shaft 21, the connecting branch rod 22 drives the anti-escape sleeve rod 26 to slide forward, the anti-escape sleeve rod 26 drives the displacement cross rod 25 to slide forward, the displacement cross rod 25 drives the positioning insert strip 27 to slide forward, until a circle of the positioning insert strip 27 is engaged with a circle of the chuck hole 24 on the rotating chuck 23, thereby fixing the rotating shaft, and the angle of the two protective cover plates 19 is also fixed, preventing the protective cover plates 19 from accidentally shaking. At this time, the ultrasonic wind speed sensor probe 16 enters the inside of the sensor retention bin 17, which protects the non-working ultrasonic wind speed sensor probe 16 through the sensor retention bin 17.
[0031] When the ultrasonic wind speed sensor probe 16 starts to work, the ultrasonic wind speed sensor probe 16 starts to descend, the ultrasonic wind speed sensor probe 16 no longer lifts the end of the actuating branch plate 20 away from the connecting branch rod 22 upward, and the end of the actuating branch plate 20 away from the connecting branch rod 22 starts to rotate downward under the action of gravity, the connecting branch rod 22 rotates upward around the branch plate rotating shaft 21, the connecting branch rod 22 drives the anti-escape sleeve rod 26 to slide backward, the anti-escape sleeve rod 26 drives the displacement cross rod 25 to slide backward, the displacement cross rod 25 drives the positioning insert strip 27 to slide backward, until a circle of the positioning insert strip 27 is disengaged from a circle of the chuck hole 24 on the rotating chuck 23, at this time the rotating shaft and the protective cover plates 19 can rotate freely. As the ultrasonic wind speed sensor probe 16 continues to descend, the ultrasonic wind speed sensor probe 16 disengages from the two protective cover plates 19, and the two protective cover plates 19 return to the horizontal state under the action of the springback force of the torsional spring, thereby closing the opening at the lower end of the sensor retention bin 17.
[0032] The rotating sleeve plate 28 is rotatably sleeved on the outer side of the supporting horizontal rod 4. An upright rotating support column 30 is fixedly arranged at the lower end of the rotating sleeve plate 28.

The longitudinal moving block 33 is arranged between the two column extension plates 31. A limiting rod 40 is slidingly arranged on the left and right side end faces of the longitudinal moving block 33. The ends of the two limiting rods 40 away from each other are respectively inserted into the two extension plate holes 32 on the two column extension plates 31, so as to fix the position of the longitudinal moving block 33. When the ends of the two limiting rods 40 away from each other are respectively pulled out of the extension plate holes 32 on the two column extension plates 31, the position of the longitudinal moving block 33 can be adjusted.
[0033] An inner concave action groove is arranged on the lower end face of the longitudinal moving block 33. The ends of the two limiting rods 40 close to each other extend into the action groove. A vertical reset spring 44 is fixedly arranged at the inner top face of the action groove. A vertical operating rod 41 is fixedly arranged at the lower end of the reset spring 44. The upper end of the operating rod 41 is fixedly connected with the lower end of the reset spring 44. The lower end of the operating rod 41 extends to the outer side of the lower end of the longitudinal moving block 33.

A slope groove is arranged on the side end face of each of the two slope plate parts 42 close to each other. The two slope grooves are symmetrically arranged. The distance between the upper ends of the two slope grooves is smaller than the distance between the lower ends of the two slope grooves. The inner width of the two slope grooves is larger than the outer opening width of the two slope grooves. A horizontal pushing side rod 43 is fixedly arranged on the left and right sides of the upper end of the operating rod 41. A pushing ball is fixedly arranged at the end of each of the two pushing side rods 43 away from each other. The two pushing balls are slidingly connected in the two slope grooves. When the operating rod 41 is pulled downward, the reset spring 44 is elongated. The operating rod 41 drives the two limiting rods 40 close to each other through the two pushing side rods 43 and the two pushing balls, so that the ends of the two limiting rods 40 away from each other are pulled out of the extension plate holes 32 on the two column extension plates 31. At this time, the longitudinal moving block 33 can slide in the two column extension plates 31. When the longitudinal moving block 33 is slid, the operating rod 41 is loosened. Under the action of the rebound force of the reset spring 44, the operating rod 41 slides upward. The operating rod 41 drives the two limiting rods 40 away from each other through the two pushing side rods 43 and the two pushing balls, so that the ends of the two limiting rods 40 away from each other are respectively inserted into the two extension plate holes 32 on the two column extension plates 31, so as to fix the position of the longitudinal moving block 33.
[0034] Two hinged seats are fixed on the outer side of the longitudinal moving block 33, and a rotating connecting block 34 is rotatably arranged between the two hinged seats.
