[0001] The invention relates to the technical field of sensors, and in particular to a long-distance ultrasonic wind speed sensor for mining. Background Art

[0002] The long-distance ultrasonic wind speed sensor for mining is an advanced measuring device designed for the complex environment of mining areas. It uses ultrasonic technology to achieve long-distance, high-precision wind speed measurement. Even within a range of hundreds of meters, it can accurately sense wind speed changes. It can monitor wind speed in real time and continuously, and quickly transmit data to the monitoring system; accurate measurement results help optimize the control of the ventilation system in the mining area, ensure the safety of operators and improve production efficiency;

[0003] The long-distance ultrasonic wind speed sensor for mining mainly includes an ultrasonic module, a signal processor, a temperature compensation module, a power supply and a housing. The ultrasonic module emits and receives ultrasonic waves. The speed at which ultrasonic waves propagate in the air will be affected by the wind speed. The wind speed is calculated by the time difference of ultrasonic wave reception.

[0004] The measurement site of the mining long-distance ultrasonic wind speed sensor is in the mine, and blasting is often required in the mining environment, including the impact generated will cause impact on the mining long-distance ultrasonic wind speed sensor. Long-term impact will damage the internal components of the mining long-distance ultrasonic wind speed sensor, thus causing limitations.

[0015] The surrounding block rotates around the deflection block, and the contact block contacts the deflection block, so that one of the deflection blocks rotates, so that the two deflection blocks that are in contact with each other due to the rotation are separated when the impact is alleviated and shaken, and the angle is restored to 90 degrees.

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention arranges a protective spring between the protective sleeve and the outer shell so that when impacted, the protective spring can reduce the force of the impact. At the same time, a counterweight block is arranged at the lower end of the outer shell so that the center of gravity of the outer shell and the counterweight block as a whole is located at the lower end of the outer shell, so that the outer shell and the counterweight block act as dampers to further alleviate the impact.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4, 5, 6, 7 and 8, a long-distance ultrasonic wind speed sensor for mining, comprising: a shell 1, a top cover 2, an ultrasonic module 3, a power supply and a controller; the power supply and the controller are both located in the shell 1; the ultrasonic module 3 is fixedly connected to the shell 1, and the upper end is exposed from the shell 1; a protective sleeve 4 is provided on the outer side of the shell 1; a protective spring 41 is fixedly connected to the outer circumference of the shell 1; the other end of the protective spring 41 is fixedly connected to the protective sleeve 4; the top cover 2 is connected to the protective sleeve 4 by bolts.

[0030] In the present invention, a counterweight 45 is fixedly connected to the bottom of the housing 1 .

[0031] In the present invention, the protection spring 41 is located on the upper side of the housing 1 , a rotation slot 42 is provided on the counterweight block 45 , a rotation rod 43 is fixedly connected in the rotation slot 42 , and a deflection block 44 is rotatably connected to the rotation rod 43 .

[0032] In the present invention, the protective sleeve 4 is fixed on the ground, the ultrasonic module 3 emits and receives ultrasonic waves, and the controller calculates the wind speed; when the mine is blasted, the shock wave generated by the blasting impacts the protective sleeve 4, and the protective sleeve 4 then impacts the protective spring 41, so that the protective spring 41 absorbs a part of the impact and transmits the force to the shell 1, so that the shell 1 shakes, so that the impact generated by the blasting on the shell 1 is weakened, so that the shell 1 and the components in the shell 1 are protected;

[0033] In the present invention, a counterweight 45 is provided at the bottom of the housing 1, so that the center of gravity of the housing 1 and the counterweight 45 is located at the lower end of the housing 1, so that when an impact is transmitted to the housing 1, the housing 1 and the counterweight 45 can play a role similar to a damper, thereby reducing the shaking of the housing 1;

[0034] In the present invention, a deflection block is arranged in the counterweight block 45. When the housing 1 is impacted and moves with the counterweight block 45, the deflection block 44 is moved together. During the movement of the deflection block 44, the center of gravity deviates from the rotating rod 43, so that the deflection block 44 rotates, and then the back and forth swing of the housing 1 after the impact is converted into rotation, so as to disperse and consume the energy of the impact, and further reduce the direct impact on the components in the housing 1.

[0035] The present invention arranges a protective spring 41 between the protective sleeve 4 and the outer shell 1 so that when impacted, the protective spring 41 can reduce the force of the impact. At the same time, a counterweight block 45 is arranged at the lower end of the outer shell 1 so that the center of gravity of the outer shell 1 and the counterweight block 45 as a whole is located at the lower end of the outer shell 1, so that the outer shell 1 and the counterweight block 45 act as a damper to further alleviate the impact. At the same time, the deflection block 44 is rotated in the counterweight block 45 to convert the impact from one direction into rotation, which further reduces the force of the impact, thereby protecting the components in the inner and outer shells 1.

[0036] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 4 , 5 , 6, 7 and 8, in the present invention, the number of the deflection blocks 44 on the rotating rod 43 is two; the two deflection blocks 44 are arranged at an angle of 90 degrees.

[0037] In the present invention, a surrounding motor 5 is fixedly connected in the rotating groove 42; a surrounding rod 51 is fixedly connected to the output end of the surrounding motor 5; a surrounding block 52 is fixedly connected to the surrounding rod 51; a contact electric push rod 53 is fixedly connected to the surrounding block 52; and a contact block 54 is fixedly connected to the output end of the contact electric push rod 53.

[0038] In the present invention, an annular groove 6 is provided on the top cover 2; a rotating ring 61 is rotatably connected in the annular groove 6; a steering rod 62 is rotatably connected to the rotating ring 61, and a cleaning motor 63 is fixedly connected to the rotating ring 61; a gear ring 64 is fixedly connected to the inner wall of the annular groove 6; a gear 65 meshing with the gear ring 64 is fixedly connected to the output end of the cleaning motor 63; a steering rod 62 is rotatably connected to the rotating ring 61; a steering electric push rod 66 is hinged between the steering rod 62 and the rotating ring 61; a cleaning silicone sheet 67 is fixedly connected to the steering rod 62.

[0039] In the present invention, a concave block 68 is fixedly connected to the top of the sleeve; the cleaning silicone sheet 67 can slide into the groove of the concave block 68.

[0040] In the present invention, two deflection blocks 44 with an included angle of 90 degrees are arranged in the counterweight block 45, so no matter which direction the impact is received, at least one deflection block can rotate, thereby preventing the impact direction from being directly toward the deflection block 44, rather than having an included angle with the deflection block 44, resulting in the deflection block 44 being unable to rotate.

[0041] In the present invention, a surrounding rod 51 and a surrounding block 52 are arranged in the rotating groove 42, and the surrounding motor 5 drives the surrounding rod 51 and the surrounding block 52 to rotate, so that the surrounding block 52 rotates around the deflection block 44, and the contact electric push rod 53 pushes the contact block 54, so that the contact block 54 contacts the deflection block 44, so that the contact block 54 of the present invention can drive one of the deflection blocks 44 to rotate, and after the deflection block 44 is rotated 90 degrees, the contact block 54 is out of contact with the deflection block 44, so that the present invention restores the two deflection blocks 44 to an angle of 90 degrees to cope with the next impact;

[0042] In the present invention, the mine environment is dusty, so the ultrasonic module 3 will be stained with dust after long-term use, so the cleaning motor 63 drives the corresponding gear 65 to rotate, so that the rotating ring 61 drives the steering rod 62 to rotate, so that the cleaning silicone sheet 67 slides out of the concave block 68, and then the steering electric push rod 66 drives the steering rod 62 to deflect in the direction close to the ultrasonic module 3 until the cleaning silicone sheet 67 contacts the ultrasonic module 3, and the cleaning silicone sheet 67 contacts all the ultrasonic modules 3 during the rotation process, so as to wipe off the dust on the ultrasonic module 3, thereby preventing the dust from affecting the monitoring results of the ultrasonic module 3;

[0043] The present invention rotates the surrounding block 52 around the deflection block 44 and contacts the deflection block 44 through the contact block 54, so that one of the deflection blocks 44 rotates, so that the two deflection blocks 44 that are in contact with each other due to the rotation are separated when the impact is alleviated and shaken, and the angle is restored to 90 degrees.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected; the scope of the present invention to be protected is defined by the attached claims and their equivalents.
