Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, in this embodiment, a radar level measuring device for a mine chute includes a main body 1, an emission component 2 and a support component 3. The emission component 2 is arranged inside the main body 1, and the support component 3 is arranged on both sides of the main body 1;

[0025] The emission component 2 includes a nail gun 201, a long nail 202 and a connecting rod 206; the nail gun 201 is fixedly connected inside the main body 1; the long nail 202 is inserted into the output end of the nail gun 201, the bottom end of the long nail 202 is fixedly connected with a nail head 203, a telescopic rod 204 is fixedly connected inside the long nail 202, a rod body 205 is fixedly connected to the outside of the telescopic rod 204, and the outer end of the rod body 205 extends out and is slidably connected to the outside of the long nail 202; the connecting rod 206 is fixedly connected to the outside of the long nail 202, and a measurement rope 207 is fixedly connected to the connecting rod 206.

[0026] During specific implementation, the spike 202 is loaded and inserted into the barrel of the nail gun 201, and then the device is fixed at the wellhead through the support assembly 3. The trigger is pulled to fire the spike 202 to the bottom of the well. When the spike 202 is driven into the bottom of the well, the nail head 203 will sink into the rock, and then push multiple rod bodies 205 to move upward. At the same time, when the spike 202 is shot into the well, it drives the measuring rope 207 to move. In this way, the depth of the ore pass can be obtained by adding the length between the rod body 205 and the measuring rope 207 to the length of the measuring rope 207 pulled out. The spike 202 can be retracted, and the depth can be calculated according to the scale 2071 on the measuring rope 207 and the scale 2071 on the spike 202. Or the measuring inductor 103 can be started to directly calculate the length of the measuring rope 207, and then add the length between the rod body 205 and the measuring rope 207. Since the measuring mechanism is directly shot to the bottom of the well, it can be applied to inclined ore passes.

[0027] In addition, it should be noted that the telescopic rod 204 includes an inner rod, an outer rod and a spring. The outer rod is fixedly connected to the inner top of the spike 202. The inner rod is slidably connected inside the outer rod. A damping medium is filled between the inner rod and the outer rod to avoid repeated vibration. A spring is sleeved outside the inner rod for returning. Multiple rod bodies 205 are fixedly connected to the bottom end of the inner rod. A plurality of chutes are provided on the outer side of the spike 202, and the plurality of rod bodies 205 are slidably limited in the chutes. The spike 202 is made of a material with high strength and high stiffness, and the hollow setting does not affect the structural strength.

[0028] As Figures 1-4 shown, further, the number of the rod bodies 205 is set to be multiple, and the multiple rod bodies 205 are all arranged around the central axis of the spike 202.

[0029] During specific implementation, when the spike 202 is driven into the bottom of the well, the nail head 203 will sink into the rock, and then push multiple rod bodies 205 to move upward. When measuring the length, the distance between the rod body 205 and the end of the measuring rope 207 needs to be calculated.

[0030] As Figure 3 shown, further, scales 2071 are provided on the outer sides of both the spike 202 and the measuring rope 207.

[0031] During specific implementation, the spike 202 can be retracted, and the depth can be calculated according to the scale 2071 on the measuring rope 207 and the scale 2071 on the spike 202.

[0032] As Figure 2 shown, further, two plate bodies 101 are fixedly connected to the outer side of the main body 1. A rotating shaft 102 is rotatably connected between the two plate bodies 101. A measuring inductor 103 is fixedly connected to the outer side of the main body 1. The upper end of the measuring rope 207 extends into the main body 1.

[0033] During specific implementation, the measurement sensor 103 can be activated to directly calculate the length of the measurement rope 207, and then add the length between the rod body 205 and the measurement rope 207. The rotating shaft 102 is provided to guide the measurement rope 207 to extend into the main body 1. It should be noted that the scale 2071 on the measurement rope 207 is added with induction materials, and the measurement sensor 103 can perform induction measurement according to the change of the scale 2071. This is the prior art and will not be elaborated too much.

[0034] In addition, it should be noted that a retractor is provided inside the main body 1, and the retractor winds the measurement rope 207. When the spike 202 is shot into the bottom of the well, it will drive the measurement rope 207 to pull out and move from the retractor. The retractor is the prior art and will not be elaborated too much.

[0035] Embodiment 2

[0036] As Figure 1 shown, in this embodiment, the support assembly 3 includes a first rotating rod 301 and a second rotating rod 304; the first rotating rod 301 is rotatably connected to one side of the main body 1, a first inner rod 302 is telescopically connected inside the first rotating rod 301, and the bottom end of the first inner rod 302 is rotatably connected to a fixing plate 303; the second rotating rod 304 is rotatably connected to one side of the main body 1, a second inner rod 305 is telescopically connected outside the second rotating rod 304, and the upper end of the second inner rod 305 is rotatably connected to the bottom surface of the first rotating rod 301.

[0037] During specific implementation, when the wellhead is small, the first inner rods 302 on both sides can be pulled out of the first rotating rod 301 to adapt to wellheads of different sizes, and then the two support assemblies 3 are rotated as a whole. At the same time, the second inner rod 305 is driven to telescopically move and rotate outside the second rotating rod 304, and then the fixing plates 303 on both sides are fixed to the bottom surface by inserting a drill rod.

[0038] As Figure 1 shown, further, fixing rods 306 are threadedly inserted into both the first rotating rod 301 and the second rotating rod 304.

[0039] During specific implementation, after the support assembly 3 is adjusted, the fixing rods 306 are threadedly inserted into the first rotating rod 301 and the second rotating rod 304 to fix the support assembly 3.

[0040] In addition, it should be noted that if the wellhead is too large, the device needs to be held for measurement.

[0041] Working principle: First, insert the long nail 202 into the barrel of the nail gun 201. Then, fix the device at the wellhead through the support assembly 3. Pull the trigger to fire the long nail 202 to the bottom of the well. When the long nail 202 is nailed into the bottom of the well, the nail head 203 will sink into the rock, and then push multiple rod bodies 205 to move upward. At the same time, the long nail 202 shot into the well drives the measuring rope 207 to move. In this way, the depth of the ore pass can be obtained by adding the length between the rod body 205 and the measuring rope 207 to the length of the measuring rope 207 pulled out. The long nail 202 can be retracted. The calculation can be performed according to the scale 2071 on the measuring rope 207 and the scale 2071 on the long nail 202, or the measuring sensor 103 can be activated to directly calculate the length of the measuring rope 207, and then add the length between the rod body 205 and the measuring rope 207. Since the measuring mechanism is directly shot to the bottom of the well, it can be applied to inclined ore passes.
