Description

Technical Field

[0001] The present application relates to the field of geological engineering surveying and mapping technology, and in particular to a water depth surveying and mapping device for mining geological resource exploration projects. Background Art

[0002] Mining geological engineering is used to accurately understand the distribution, shape and scale of ore bodies, provide basic data for mineral resource reserve calculation and mining planning, and map the topography and tunnels of mines, which helps to reasonably design ventilation and drainage systems to ensure the safety of miners. For the mapping of mine geology, it is necessary to map the holes on its surface, especially some holes with accumulated water. In this case, it is necessary to use a water depth mapping device to map the holes to obtain the depth of the holes. In the existing technology, weights and ropes are generally used for depth exploration. The weights drive the ropes to go deep into the holes with accumulated water. The rope will be pulled continuously until it reaches the bottom of the cave. At this time, the water depth will be displayed by the continuously pulled rope, but this method will bring some problems: First, the inner walls of some holes on the surface of mines are not smooth, and are not even vertically distributed. This causes the heavy objects and ropes entering the holes to rub against the inner walls of the holes. The curved inner walls of the holes will generate friction and wear on the continuously moving ropes. If for some deeper holes, the rope will be more susceptible to wear and tear under the weight of the heavy objects. Not only will it be prone to breakage, but the curved hole distribution will also reduce the accuracy of water depth mapping. Summary of the Invention

Protective cylinders are fixedly installed on the outer surface of the outer limit cylinder, and the inner limit cylinder, outer limit cylinder and connecting rope are coaxially distributed.

[0005] As a preferred solution of the present invention, a fixed block is fixedly installed at the bottom of the inner wall of the water inlet hole, a limiting column is movably sleeved in the middle of the fixed block, a rubber pad is glued to the bottom of the limiting column, the bottom of the rubber pad is in contact with the fixed block, and multiple groups of water holes are opened on the top of the fixed block.

[0006] As a preferred solution of the present invention, the diameters of the limiting column and the rubber pad are smaller than the inner diameter of the water inlet hole, and a plurality of sealing protrusions are provided at the bottom of the rubber pad. The number of the sealing protrusions is equal to the number of the water holes, and they are adapted to be connected with each other.

[0007] As a preferred solution of the present invention, the sealing rings are provided in two groups and are respectively glued to the upper and lower sides of the top of the piston, and there is an interference fit between the sealing rings and the inner wall of the sealing cylinder.

[0008] As a preferred solution of the present invention, an annular protrusion is provided on the top of the support ring, and is adapted to fit the bottom of the inner wall of the inner limiting cylinder on the outer side of the annular protrusion.

[0009] As a preferred solution of the present invention, the support bars are provided in four groups and are equidistantly distributed on the inner wall of the outer limiting cylinder. The support bars abut against the top and outer side of the inner limiting cylinder.

[0012] As a preferred solution of the present invention, a plurality of groups of buffer pads are glued to the bottom of the mounting frame, and the buffer pads are made of rubber blocks.

[0013] The beneficial effects of the present invention are as follows: 1. This device has been redesigned, and an inner and outer nested inner limit cylinder and outer limit cylinder are added to the outer surface of the connecting rope to avoid direct contact between the connecting rope and the bend of the inner wall of the hole and wear. A support ring is installed on the surface of the connecting rope, and the inner limit cylinder is adapted and installed using the support ring. Then, multiple groups of support bars installed on the inner wall of the outer limit cylinder are coaxially hung on the top of the inner limit cylinder. When the connecting rope is lowered, the outer limit cylinder located on the outside hooks the first bend of the inner wall of the hole. At this time, the connecting rope drives the inner limit cylinder to break away from the outer limit cylinder. When the belt is in the second position, it moves to the inside of the positioning cylinder and continues to move downward. When the inner limiting cylinder reaches the second bend of the inner wall of the hole, the outer side of the inner limiting cylinder hooks this position and breaks away from the support ring. At this time, since the connecting rope continues to move downward, it will drive belt 2 and belt 1 to make continuous rolling motion. Belt 2 rolls between the upper and lower grooves 2 and makes rolling contact with the connecting rope, while belt 1 rolls between the upper and lower grooves 1, thereby avoiding direct contact between the connecting rope and the curved part of the inner wall of the hole and causing huge wear, thereby effectively extending the service life of the connecting rope.

[0014] 2. This device also changes the way of water depth mapping. It adopts the principle of water pressure sensing and does not require traditional rope retraction and visual inspection, which greatly improves the accuracy of the mapping results. A vertical water inlet hole is opened in the middle of the counterweight ball for entering accumulated water and placing a sealing cylinder. A sealing sleeve composed of a piston and a spring is set on the inner wall of the sealing cylinder. When the accumulated water exerts pressure on the piston through the water inlet hole, it continuously pushes the piston upward and compresses the spring. The rebound force generated by the spring offsets the continuously increasing water pressure. At the same time, the water depth data can be displayed by using the stroke of the piston and the scale on the surface of the sealing cylinder.

[0015] 3. Then, a "one-way valve" structure is formed by using the fixed block, limit column and rubber pad. When the counterweight ball continues to penetrate the water hole, the limit column and rubber pad move upward under the action of water pressure and open the water hole to allow the accumulated water to enter the deep water inlet hole. When the counterweight ball reaches the lowest point and is recovered upward, at this time, both sides of the upper side of the fixed block are filled with water. When the water depth of the counterweight ball is decreasing, the water pressure at the bottom of the fixed block is less than the water pressure at its top. At this time, such a water pressure difference will firmly press the limit column and rubber pad on the top of the fixed block and seal the water hole, thereby maintaining the established position of the piston and achieving the purpose of accurate water depth mapping.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] See also Figures 1-11 The embodiment of the present invention provides a water depth surveying device for mining geological resource exploration engineering, including a mounting frame 1 and a buffer pad 2. A frame 3 is installed on the top of the mounting frame 1. A winding roller 4 and a guide roller 6 are rotatably installed inside the frame 3. A motor 5 is installed on the side of the frame 3. The motor 5 is used to drive the winding roller 4 to rotate. A connecting rope 7 is wound around the outer surface of the winding roller 4. The bottom end of the connecting rope 7 is fixedly connected to a sealing cylinder 9. A counterweight ball 10 is fixedly installed at the bottom of the outer surface of the sealing cylinder 9. A water inlet hole 11 is opened at the bottom of the counterweight ball 10. A piston 12, a sealing ring 13 and a spring 14 are provided on the middle sealing sleeve of the inner wall of the sealing cylinder 9. One end of the piston 12 is sealed in the water inlet hole 11. The other end of the piston 12 is elastically supported on the inner wall of the sealing cylinder 9 by a spring 14. The sealing cylinder 9 is made of transparent high-strength glass, and a scale is opened on the surface of the sealing cylinder 9. The outer surface of the connecting rope 7 is fixedly installed with a support ring 8 located above the sealing cylinder 9, and the top of the support ring 8 is movably connected to the inner limit cylinder 19, and the upper and lower sides of the outer surface of the inner limit cylinder 19 are provided with multiple groups of card grooves 20, and the inner walls of the upper and lower card grooves 20 are wound with belts 21, and the outer surface of the inner limit cylinder 19 is fixedly installed with a protective cylinder 23, and the outer surface of the inner limit cylinder 19 is movably sleeved with an outer limit cylinder 24, and the top of the inner wall of the outer limit cylinder 24 is fixedly connected with multiple groups of support bars 29, one side of the support bar 29 abuts against the top of the outer surface of the inner limit cylinder 19, and the upper and lower sides of the outer surface of the outer limit cylinder 24 are provided with multiple groups of card grooves 25, and the inner walls of the upper and lower card grooves 25 are wound with belts 26, and the outer surface of the outer limit cylinder 24 is fixedly installed with a protective cylinder 28, and the inner limit cylinder 19, the outer limit cylinder 24 and the connecting rope 7 are coaxially distributed; This device has been redesigned, and an inner limit cylinder 19 and an outer limit cylinder 24 that are nested inside and outside are added to the outer surface of the connecting rope 7 to avoid direct contact between the connecting rope 7 and the curved part of the inner wall of the hole and wear. By installing a support ring 8 on the surface of the connecting rope 7, the inner limit cylinder 19 is adapted and installed using the support ring 8, and then, multiple groups of support bars 29 installed on the inner wall of the outer limit cylinder 24 are coaxially hung on the top of the inner limit cylinder 19. During the lowering process of the connecting rope 7, the outer limit cylinder 24 located on the outside hooks the first curved part of the inner wall of the hole. At this time, the connecting rope 7 drives the inner limit cylinder 19 to disengage from the outer limit cylinder. The inner limit cylinder 19 moves to the inside of the cylinder 24 and continues to move downward. When the inner limit cylinder 19 reaches the second bend of the inner wall of the hole, the outer side of the inner limit cylinder 19 hooks this position and breaks away from the support ring 8. At this time, since the connecting rope 7 continues to move downward, it will drive the belt 2 26 and the belt 1 21 to make continuous rolling motion. The belt 2 26 rolls between the upper and lower grooves 25 to produce rolling contact with the connecting rope 7, and the belt 1 21 rolls between the upper and lower grooves 20, thereby avoiding direct contact between the connecting rope 7 and the curved part of the inner wall of the hole and causing huge wear, thereby effectively extending the service life of the connecting rope 7.

[0021] Among them, a fixing block 15 is fixedly installed at the bottom of the inner wall of the water inlet hole 11, and a limiting column 17 is movably sleeved in the middle of the fixing block 15. A rubber pad 18 is glued to the bottom of the limiting column 17, and the bottom of the rubber pad 18 abuts against the fixing block 15. A plurality of water holes 16 are opened on the top of the fixing block 15; This device also changes the way of water depth measurement and mapping. It adopts the principle of water pressure sensing and does not require traditional rope retraction and visual inspection, which greatly improves the accuracy of the measurement results. A vertical water inlet hole 11 is opened in the middle of the counterweight ball 10 for entering accumulated water and placing the sealing cylinder 9. The inner wall of the sealing cylinder 9 is sealed by a piston 12 and a spring 14. When the accumulated water exerts pressure on the piston 12 through the water inlet hole 11, the piston 12 is continuously pushed upward and the spring 14 is compressed. The rebound force generated by the spring 14 offsets the continuously increasing water pressure. At the same time, the water depth data can be displayed using the travel of the piston 12 and the scale on the surface of the sealing cylinder 9.

[0022] Then, a "one-way valve" structure is formed by using the fixed block 15, the limit column 17 and the rubber pad 18. When the counterweight ball 10 continues to penetrate the water hole, the limit column 17 and the rubber pad 18 move upward under the action of water pressure and open the water hole 16, so that the accumulated water can enter the deep water inlet hole 11. When the counterweight ball 10 reaches the lowest point and is recovered upward, at this time, both sides of the upper side of the fixed block 15 are filled with water. When the water depth of the counterweight ball 10 is decreasing, the water pressure at the bottom of the fixed block 15 is less than the water pressure at its top. At this time, such a water pressure difference will firmly press the limit column 17 and the rubber pad 18 on the top of the fixed block 15 and seal the water hole 16, thereby maintaining the established position of the piston 12 and achieving the purpose of accurate water depth mapping.

[0023] The diameter of the limiting column 17 and the rubber pad 18 is smaller than the inner diameter of the water inlet hole 11. The bottom of the rubber pad 18 is provided with multiple groups of sealing protrusions 30. The number of the sealing protrusions 30 is equal to the number of the water holes 16, and they are mutually adapted and snap-fitted. like Figure 4 As shown, the limiting column 17 relies on the rubber pad 18 to squeeze the top of the fixed block 15 downward, and the sealing protrusion 30 is stuck in the water hole 16 to achieve sealing of the fixed block 15. When the accumulated water passes through the water hole 16, the limiting column 17 and the rubber pad 18 are separated from the surface of the fixed block 15 upward under the action of water pressure, allowing water to flow.

[0024] Among them, the sealing ring 13 is provided in two groups and is glued to the upper and lower sides of the top of the piston 12 respectively, and the sealing ring 13 is interference fit with the inner wall of the sealing cylinder 9; The sealing ring 13 is used to seal the top of the piston 12 to prevent excessive water pressure from leaking upward along the gap between the bottom of the piston 12 and the inner wall of the water inlet hole 11 .

[0025] Among them, the top of the support ring 8 is provided with an annular protrusion, and is adapted to fit the bottom of the inner wall of the inner limiting cylinder 19 on the outside of the annular protrusion; like Figure 3 As shown, the annular protrusion on the top of the support ring 8 supports the inner limiting cylinder 19 upward, and at the same time, it also enables the inner wall of the inner limiting cylinder 19 and the connecting rope 7 to maintain a coaxial distribution.

[0026] The support bars 29 are arranged in four groups and are equidistantly distributed on the inner wall of the outer limiting cylinder 24. The support bars 29 abut against the top and outer side of the inner limiting cylinder 19. The part where the support bar 29 abuts against the inner limit tube 19 is distributed in an "L" shape. On the one hand, the support bar 29 is used to realize the limiting support of the outer limit tube 24. At the same time, the support bar 29 is used to make the outer limit tube 24 coaxial with the inner limit tube 19, so that the outer limit tube 24 will not take the inner limit tube 19 away when it is separated from the inner limit tube 19.

[0027] Among them, the inner wall of the inner limit cylinder 19 is fixedly connected to a plurality of groups of isolation strips 22, the top cross-sectional shape of the isolation strips 22 is semicircular, the number of the isolation strips 22 is equivalent to the belt 21, and the plurality of groups of isolation strips 22 and the belt 21 are equidistantly distributed around the circumference in an adjacent and staggered manner. The inner wall of the outer limit cylinder 24 is fixedly connected to a plurality of groups of isolation strips 27, the top cross-sectional shape of the isolation strips 27 is semicircular, the number of the isolation strips 27 is equivalent to the belt 26, and the plurality of groups of isolation strips 27 and the belt 26 are equidistantly distributed around the circumference in an adjacent and staggered manner. The function of isolation strip 27 and isolation strip 1 22 is to assist the connecting rope 7 to move to the surface of belt 2 26 and belt 1 21. When the connecting rope 7 just contacts isolation strip 27 and isolation strip 1 22, the semicircular design of isolation strip 27 and isolation strip 1 22 is used to guide the connecting rope 7 to the side of belt 2 26 and belt 1 21. At this time, the inner limit cylinder 19 and the outer limit cylinder 24 will be driven to rotate actively as a whole to ensure that belt 1 21 and belt 2 26 can contact the connecting rope 7 and produce relative rolling.

[0028] The axial cross-section of the limiting column 17 is T-shaped, and the outer diameters of the limiting column 17 and the rubber pad 18 are equal; The T-shaped design of the limiting post 17 enables it to cooperate with the fixing block 15 during the upward movement to prevent it from falling off.

[0029] Among them, multiple groups of buffer pads 2 are glued to the bottom of the mounting frame 1, and the buffer pads 2 are made of rubber blocks.

[0030] The buffer pad 2 provides elastic buffer support for the entire device, preventing the mounting frame 1 from falling directly on the survey area, and can effectively protect the device.

[0031] Working principle: First, place the mounting frame 1 at the entrance of the ore body. After it stabilizes, place the counterweight ball 10 into the entrance. Start the motor 5, which drives the winding roller 4 to rotate, release the connecting rope 7, and allow the counterweight ball 10 to immerse in the water under the action of gravity. At the same time, it drives the connecting rope 7, support ring 8, inner limit cylinder 19, and outer limit cylinder 24 downward. Then, during the process of the balancing ball 10 descending, water enters the interior of the balancing ball 10 along the bottom opening of the water inlet hole 11. The limiting column 17 moves upward under the action of the water pressure and drives the rubber pad 18 to break away from the abutment with the fixed block 15, so that the water through hole 16 is connected to the deep part of the water inlet hole 11. The accumulated water in the hole begins to act on the bottom end of the water inlet hole 11 and drives the water inlet hole 11 to move upward, continuously compressing the spring 14. At this time, the water depth of the balancing ball 10 is converted into the compressed stroke of the spring 14, that is, the displacement of the piston 12. Then, when the counterweight ball 10 moves to the position where the inner wall is bent, the top outer edge of the outer limit cylinder 24 is stuck and limited with the inner wall of the hole, and the outer limit cylinder 24 drives the support bar 29 to separate from the surface of the inner limit cylinder 19, and the inner limit cylinder 19 continues to move downward with the connecting rope 7. During the lowering process, the connecting rope 7 will contact the inner wall of the outer limit cylinder 24 and slide relatively. When the connecting rope 7 contacts the surface of the second isolation bar 27, the second isolation bar 27 will push the connecting rope 7 laterally through its surface, so that the connecting rope 7 contacts the second belt 26. At this time, the entire outer limit cylinder 24 will rotate around the axis of the connecting rope 7, and the connecting rope 7 will drive the second belt 26 to move synchronously. The second belt 26 starts to rotate around the inner wall of the second slot 25 to avoid sliding wear of the connecting rope 7. Then, when encountering the second curved position in the hole, the inner limiting cylinder 19 is stuck with the curved portion of the inner wall of the hole and is limited. At this time, the connecting rope 7 will contact the belt 1 21 under the guidance of the isolation strip 1 22, thereby driving the belt 1 21 to move, causing relative rolling between the connecting rope 7 and the belt 1 21, thereby reducing the wear of the connecting rope 7; Finally, when the weighted ball 10 reaches the bottom of the hole, the water pressure is maximum, the motor 5 is reversed, and the connecting rope 7 is driven to be recovered upward. At this time, the depth of the weighted ball 10 decreases, and the water pressure on the piston 12 decreases. Figure 2 As shown, the pressure on the upper side of the fixing block 15 is greater than the water pressure on the lower side, so that the limit column 17 drives the rubber pad 18 to automatically move downward to abut against the top of the fixing block 15, and at the same time, the sealing protrusion 30 is firmly stuck in the water hole 16. As the connecting rope 7 continues to rise, the water hole 16 is blocked and the piston 12 no longer moves, thereby retaining the displacement of the piston 12. Finally, the water depth can be judged by the scale on the surface of the sealing cylinder 9. During the recovery process of the connecting rope 7 , the inner limiting cylinder 19 is first re-sleeved into place through the support ring 8 , and then the outer limiting cylinder 24 is re-installed on the surface of the outer limiting cylinder 24 using the support bar 29 .
