Description

Technical Field

[0001] The invention relates to the technical field of mine detection equipment, in particular to an easily adjustable mine water detection radar and an adjustment method. Background Art

[0002] It is an area where humans mine coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. Coal surveying is to survey the geology of the coal area, whether the geology is convenient for mining and the composition of the coal. In the process of coal surveying, water-penetrating radar is required. It is an effective means of detecting underground targets developed in recent decades. It is a non-destructive detection technology. Compared with other conventional underground detection methods, it has the advantages of fast detection speed, continuous detection process, high resolution, convenient and flexible operation, and low detection cost. It is increasingly widely used in the field of engineering survey.

[0003] The authorization publication number is CN214147236U, and the name is a three-dimensional ground penetrating radar. It mentions that "the user drives the wheel 38 to rotate by turning the handle 4, thereby driving the bidirectional screw 31 to rotate. The rotation of the wheel 38 drives the other wheel 38 to rotate under the action of the belt 39, thereby rotating the other bidirectional screw 31. By turning any one of the handles 4, the movement of the two sets of lifting components 3 can be controlled at the same time, which is convenient for adjusting the distance between the radar body 1 and the ground." When encountering a higher obstacle, the handle 4 needs to be operated to achieve the lifting of the radar body 1 to avoid direct contact. After crossing the obstacle, the handle 4 needs to be turned back to lower the radar body 1 to a suitable position to facilitate detection operations. However, the terrain is often uneven, and the handle 4 needs to be adjusted multiple times. The operation is time-consuming and labor-intensive, which affects the detection efficiency, and the applicability needs to be improved. Summary of the invention

[0018] 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.

[0019] See also Figures 1 to 6 The present invention provides a mine water detection radar that is easy to adjust, including a casing 1 and a radar body 24 arranged in the casing 1, the radar body 24 is connected to a lifting mechanism for driving the radar body 24 to rise and fall, the lifting mechanism includes a threaded barrel 17, a stud 26, a gear 28, and a guide frame 20, the gear 28 is used to drive the stud 26 to rotate, the stud 26 is used to drive the threaded barrel 17 to rise and fall, the end of the threaded barrel 17 is connected to the radar body 24, the guide frame 20 is used to guide the radar body 24, a detection hole 25 is provided at the bottom of the casing 1, the gear 28 is connected to a shielding mechanism for shielding the detection hole 25, a distance measuring mechanism is connected to the top front end of the casing 1, and the shielding mechanism is connected to the distance measuring mechanism.

[0020] The motor 5 can drive the cam 9, gear 1 27, and rotating column 21 to rotate. The rotating column 21 drives the baffle 23 to rotate, thereby gradually opening the detection hole 25. At the same time, the rotation of gear 1 27 also drives gear 2 28 to rotate, thereby realizing the rotation of the stud 26. Combined with the use of the threaded cylinder 17, it is convenient to drive the radar body 24 and the detection disk 29 to move downward synchronously, so that the detection disk 29 passes through the detection hole 25 and is at a suitable height position, thereby facilitating the detection operation. Furthermore, the rotation of the cam 9 causes the connector 10 to gradually slide toward the tip of the cam 9, thereby pushing the connector 10, the movable frame 6, and the two connecting columns 11 forward, and the spring 13 is gradually compressed, and the sliding block 14 slides on the guide groove 15, thereby opening the box door 8 to expose the ranging sensor 16, so as to facilitate the detection of the distance between the obstacle in front and the detection disk 29, and feed back the detection information to the controller. The controller is installed in the box body 7, and the controller is electrically connected to the motor 5 to control the forward and reverse rotation of the motor 5 to realize the lifting and lowering of the radar body 24 and the detection disk 29, thereby avoiding obstacles and preventing damage, and the use is safe and reliable.

[0021] In normal use, the baffle 23 is in Figure 6 The detection disc 29 is at position a in the middle, and the detection disc 29 passes through the detection hole 25, and the bottom of the radar body 24 is connected to the bottom of the housing 1. This position is the best exploration height, and the door 8 opens at the maximum angle. When encountering an obstacle of general height, the motor 5 drives the cam 9, gear 1 27, and rotating column 21 to rotate synchronously, so that the baffle 23 rotates to position b, and the detection disc 29 rises a certain distance. At this time, the opening angle of the door 8 is reduced, but it does not affect the use of the ranging sensor 16, and it is still in an exposed state. When encountering a higher obstacle, the baffle 23 rotates to position c, and the detection disc 29 continues to rise. At this time, the bottom surface of the detection disc 29 is level with or slightly higher than the bottom surface of the detection hole 25, effectively avoiding the detection disc 29 from contacting the obstacle, and the opening angle of the door 8 is further reduced, and it does not affect the use of the ranging sensor 16.

At the same time, the baffle 23 rotates to gradually close the detection hole 25. Further, the tip of the cam 9 moves away from the connector 10, and the compressed spring 13 drives the moving frame 6 and the two connecting columns 11 to move back, and synchronously drives the two sliding blocks 14 to move back, so that the box door 8 is gradually closed. When the radar body 24 rises to a suitable height position, the baffle 23 completely blocks the detection hole 25, realizing good protection for the radar body 24 and the detection plate 29, and the box door 8 is in a closed state, realizing protection for the ranging sensor 16.

[0023] The lifting mechanism also includes two guide plates 18, which are connected to both sides of the radar body 24, and are slidably connected to the guide frame 20, which is fixed in the housing 1. When the radar body 24 is lifted or lowered, the guide plates 18 and the guide frame 20 slide relative to each other, thereby improving the lifting stability of the radar body 24 and the detection plate 29, facilitating the alignment of the detection plate 29 with the detection hole 25, and avoiding misalignment.

[0024] Gear 2 28 is rotatably connected to the inner top of the housing 1, and the end of the stud 26 is fixedly connected to gear 2 28. Gear 1 27 is rotatably connected to the housing 1, and gear 1 27 is meshed with gear 2 28. The stability of the rotation of gear 1 27 and gear 2 28 is improved, and the traditional effect is improved. At the same time, the meshing connection method is adopted, the transmission ratio is constant, and the efficiency is high.
