[0002] The air shaft is a shaft specially used for ventilation in the mine. The shaft for fresh air is the air inlet shaft; the shaft for exhausting polluted air is the air outlet shaft. The number of air shafts set up in each mine field is related to the ventilation system adopted and the layout of the air shafts. Each ventilation system must have at least one air inlet shaft and one air outlet shaft. The air inlet shaft can be a cage shaft, an inclined shaft for string car lifting, an inclined ramp or a main horizontal shaft, or a dedicated air inlet shaft can be used. The air outlet shaft is generally a dedicated shaft, and most of the cross-sections are circular.

Positioning holes 25 are formed at the positions of the four corners of the top end of the installation frame 23. At the positions of the four corners of the bottom end of the supporting plate 22, support pads 26 are installed.

[0027] A base 3 is placed on the top end of the supporting plate 22. At the position near the top end of the side surface of the base 3, a fixing frame 31 is installed. At the positions near the middle of both sides of the fixing frame 31, fixing bolts 32 are movably screwed. At the positions of the four corners of the bottom end of the fixing frame 31, limiting rods 33 are installed. The outer diameter of the bottom end of the fixing bolt 32 is adapted to the inner diameter of the threaded hole 24, and the bottom end of the fixing bolt 32 extends into the threaded hole 24 and is movably screwed with it. The outer diameter of the bottom end of the limiting rod 33 is adapted to the inner diameter of the positioning hole 25, and the bottom end of the limiting rod 33 extends into the positioning hole 25 and is movably limited and clamped with it. A wind speed detector 34 is installed on the top end of the base 3. At the position near the middle of the top end of the wind speed detector 34, a rubber column 36 is installed.

[0028] In the initial state, the installation frame 23, the base 3, and all the components installed on the base 3 are arranged inside the protective cover 14, so that the protective cover 14 can protect the installation frame 23, the base 3, and all the components installed on the base 3.

[0029] The specific model of the wind speed detector 34 is: GFY15X mine-used two-way wind speed sensor, hereinafter referred to as "sensor", which is applicable to ventilation roadways, air inlets, fan wellheads and other roadways in coal mines to detect the wind speed and wind direction. The sensor has functions such as sound and light alarm and infrared remote control, can display the wind speed and wind direction locally, and continuously and automatically convert the measured value into a standard electrical signal and transmit it to the connected equipment.

[0030] The characteristics of the wind speed detector 34 are:

[0031] 1. It adopts the differential pressure principle, with wide measuring range, high precision, good long-term stability and long service life. 2. The shell adopts a new waterproof and dustproof design, and the protection level reaches IP65;

[0032] 3. Adopting a new power supply solution and startup mechanism, the whole machine has lower power consumption and longer transmission distance;

[0033] 4. It has perfect fault diagnosis function to ensure that the sensor can identify abnormality in time;

[0034] 5. It has a "black box" function that can store historical data, faults, alarms, operations and other records, and can effectively identify the occurrence of misoperation and false alarms.

[0035] The sensor consists of power supply circuit, intelligent signal processing, sound and light alarm circuit, wind speed probe, signal conversion circuit, remote control receiving circuit, display circuit, signal output circuit, etc. The circuit working principle block diagram of the sensor is as follows: Figure 6 shown.

[0036] The sensor wind speed probe detects wind speed and direction based on the differential pressure principle. The sensor CPU receives the measurement signal of the wind speed probe, and after calculation and compensation, displays the wind speed value through the digital tube, and outputs the signal to the matching device for remote collection.

[0037] During use, when the wind speed detection instrument 34 fails and needs to be repaired, the user can start the two sets of electric push rods 15, so that under the operation of the two sets of electric push rods 15, the ends of the two sets of electric push rods 15 can be telescopically moved downward, so that the two sets of extension plates 2 can move downward accordingly, so that the supporting plate 22 can move downward accordingly, so that the mounting frame 23, the base 3 and all the parts mounted on the base 3 can move downward accordingly, so that the bottom surface of the four sets of support pads 26 can finally be set in contact with the ground. At this time, the two sets of electric push rods 15 can be closed. After that, the user can conveniently rotate the two sets of fixing bolts 32 accordingly, so that the bottom ends of the two sets of fixing bolts 32 can be rotated out from the corresponding threaded holes 24 respectively. After that, the user can move the fixing frame 31 upward, so that the four sets of limit rods 33 can be moved out from the inside of the corresponding positioning holes 25 respectively, so that the base 3 can be moved out from the inside of the mounting frame 23, so that the disassembly operation between the wind speed detection instrument 34 and the mounting frame 23 can be completed. At this time, the wind speed detection instrument 34 can be subjected to corresponding maintenance operations. After the maintenance is completed, the supporting plate 22 and the wind speed detection instrument 34 can be moved upward to the initial height according to the above operation, so that the bottom end of the protective cover 14 can be fitted with the top end of the supporting plate 22, so that the top end of the rubber column 36 can be fitted with the top inner wall of the protective cover 14, so that the top ends of the four groups of rubber blocks 37 can be fitted with the top inner wall of the protective cover 14, so as to protect the top surface of the wind speed detection instrument 34, so as to avoid the problem of malfunction of the wind speed detection instrument 34 caused by the collision between the top surface of the wind speed detection instrument 34 and the top inner wall of the protective cover 14.
