Description

A borehole measuring device for geological and mineral exploration Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically a borehole measuring device for geological and mineral exploration. Background Technology

[0002] Geological and mineral exploration mainly involves collecting and analyzing geological data to understand information such as geological structure and mineral distribution. Drilling is required when conducting geological and mineral exploration work. After drilling, the depth of the borehole needs to be measured, which requires the use of borehole measuring equipment to assist in the operation.

[0003] Existing geological and mineral exploration borehole measuring devices measure borehole depth by connecting the measuring instrument to a cable and placing it into the drilled hole. When the measuring instrument touches the ground or water surface, it sends a signal to measure the borehole depth. However, during long-term use and observation, it was found that there is a gap and distance between the measuring instrument and the borehole wall when measuring borehole depth. Due to the swaying of the cable when it is lowered and wound up, the measuring instrument sways during descent and collides with the borehole wall, causing damage to the measuring instrument and affecting the accuracy of the measurement data. Summary of the Invention

[0004] The purpose of this invention is to provide a drilling measurement device for geological and mineral exploration, which can make the measuring instrument more stable when sliding down and up in the hole, and prevent the measuring instrument from colliding with the inner wall of the hole due to shaking when sliding in the hole.

[0005] The technical solution of this utility model is:

[0006] A drilling and measuring device for geological and mineral exploration includes: a cable assembly and a measuring instrument; a housing fitted over the measuring instrument with a gap between the inner wall of the housing and the measuring instrument; and multiple fixed rods connected between the inner wall of the housing and the measuring instrument; and multiple sliding parts disposed on the housing, each of the sliding parts including: a fixed seat, a buffer, and a sliding body, wherein the fixed seat is connected to the housing through the buffer, and the sliding body is mounted on the fixed seat for sliding contact with the inner wall of the borehole.

[0007] Furthermore, the casing has a ring structure, and multiple sliding parts are arranged in a ring array with the center of the casing as the axis.

[0008] Furthermore, each of the buffer components includes: a buffer spring, one end of which is connected to the fixed base and the other end of which is connected to the housing; and a guide rod, which has multiple sliding channels on the housing, each sliding channel corresponding to a buffer component, one end of which is slidably inserted into the sliding channel and the other end of which is connected to the fixed base.

[0009] Furthermore, the sliding body is a rotary wheel structure.

[0010] Furthermore, it also includes a guide component, which is disposed on the support plate of the cable assembly to guide and limit the cable when the cable assembly is lowered and retracted.

[0011] Furthermore, the guiding assembly includes: a fixing plate connected in front of the two support plates of the cable assembly, the fixing plate having a limiting hole for the cable to pass through; two limiting arms symmetrically arranged on both sides of the limiting hole on the fixing plate, one end rotatably connected to the fixing plate, and the other end converging upwards towards the limiting hole; two limiting wheels, the shafts of which are mounted on the other end of the limiting arms, and the rolling surfaces of the two limiting wheels are arranged opposite to each other for clamping the cable; and two support springs connected between the corresponding limiting arms and the fixing plate.

[0012] Furthermore, a clamping groove is formed on the rolling surface of the limiting wheel along its rolling direction.

[0013] Furthermore, a fixing ring is fitted inside the limiting hole, and the inner ring surface of the fixing ring is provided with bristles.

[0014] Furthermore, a ring-shaped rubber pad is connected to the end of the fixing ring closest to the ground.

[0015] Furthermore, an elastic sealing sleeve is fitted over the buffer component, with the two ends of the elastic sealing sleeve connected to a fixing seat and a housing, respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the casing and the sliding part on the outside of the casing, makes the measuring instrument stable when falling and rising in the channel. Multiple sliding bodies slide on the inner wall of the hole, making the position of the casing and the measuring instrument more stable, reducing the possibility of the measuring instrument shaking and colliding with the inner wall of the hole when falling and rising in the hole, which would cause damage to the measuring instrument, thereby improving the stability of the measurement.

[0018] 2. This utility model, by setting a limiting component, uses a limiting arm, limiting wheels, and a support spring to limit the cable clamped between the limiting wheels, ensuring the stability of the cable when it is below and coiled up, thereby ensuring the stability of the measuring instrument 14. Furthermore, the tensioning effect of the support spring on the limiting arm exerts a compressive force on the cable located between the limiting wheels. When water contained in the hole is adsorbed onto the cable, the rolling compression of the limiting wheels squeezes out the adsorbed water from the cable, reducing the moisture content inside the cable and thus reducing the corrosion caused by water. This ensures the stability of the cable structure and, consequently, the stability of the measuring instrument's lifting and lowering. Attached Figure Description

[0027] Example

[0028] As shown in Figures 1 and 2, a drilling measurement device for geological and mineral exploration includes: a cable assembly and a measuring instrument 14. The measuring instrument 14 itself has a housing. To match the drilling hole, the housing of the measuring instrument 14 is generally cylindrical. The cable assembly includes: two support plates 1 and a winding post 12 connected between the two support plates 1. One end of the winding post 12 is connected to a motor drive, and a cable 12 is wound on the winding post. As shown in Figure 2, the drilling measurement device in this embodiment also includes: a sleeve 16 and multiple sliding parts. The sleeve 16 is fitted outside the measuring instrument 14, and there is a gap between the inner wall of the sleeve 16 and the measuring instrument 14. Multiple fixing rods 15 are connected between the inner wall of the sleeve 16 and the measuring instrument 14. Multiple sliding parts are disposed on the sleeve 16. Each sliding part includes: a fixing seat 19, a buffer, and a sliding body 110. The fixing seat is connected to the sleeve 16 through the buffer and the sliding body 110. The measuring instrument 14 is mounted on the fixed base 19. When the measuring instrument 14 passes under the cable 13 to the orifice opening, the buffer is compressed to adapt to orifices of different diameters, allowing the sliding body 110 to enter the orifice. Through the recovery of the buffer, the sliding body abuts against the inner wall of the orifice. Note that the recovery tension of the buffer should not be too large to prevent excessive friction between the sliding body and the inner wall of the orifice. At this time, the cable 13 and the sliding body slide on the inner wall of the orifice. Through the buffering effect of the buffer, the measuring instrument 14 is more stable. When the measuring instrument 14 falls to the bottom of the orifice or touches the water surface, it will send a feedback signal. At this time, the depth of the orifice can be measured by observing the length of the cable 13 that has fallen. Then, the motor 11 rotates the winding column 12 to retract the cable 13 and pull up the measuring instrument 14. Similarly, during the pulling process, the measuring instrument 14 slides in the orifice through the sliding part on the housing, and the buffer reduces its shaking and improves stability.

[0029] In some embodiments, in order to make the housing 16 more adaptable to the structure of the channel, as shown in FIG2, the housing 16 is a ring structure, and multiple sliding parts are arranged in a ring array with the center of the housing 16 as the axis.

[0030] In the embodiment shown in Figure 2, each buffer includes a buffer spring 18 and a guide rod 17. One end of the buffer spring 18 is connected to the fixed base 19, and the other end is connected to the housing 16. The guide rod 17 has multiple sliding channels on the housing 16, each sliding channel corresponding to a buffer. One end of the guide rod 17 is slidably inserted in the sliding channel, and the other end is connected to the fixed base 19. By pressing the fixed base 19, the buffer spring 18 is compressed, and the other end of the guide rod slides along the sliding channel, making the compression of the buffer spring 18 more stable.

[0031] As shown in Figure 2, the sliding body 110 is a rotary wheel structure.

[0032] In the embodiments shown in Figures 1 and 3, a guide component is further included, which is disposed on the support plate 1 of the cable assembly to guide and limit the cable when the cable assembly is lowered and retracted.

[0033] As shown in Figure 3, the guide assembly includes: a fixed plate 2, two limiting arms 21, and two limiting wheels 22. The fixed plate 2 is connected to the two support plates 1 of the cable assembly, and limiting holes for cable passage are formed on the fixed plate 2. The two limiting arms 21 are symmetrically arranged on both sides of the limiting holes on the fixed plate 2, with one end rotatably connected to the fixed plate 2 and the other end converging upwards towards the limiting holes. The shafts of the two limiting wheels 22 are mounted on the other ends of the limiting arms 21, and the rolling surfaces of the two limiting wheels 22 are arranged opposite each other to clamp the cable. When the cable 13 is lowered and rolled up, the limiting wheel 22 rolls and clamps the cable to ensure the stability of the cable when it is lowered and rolled up. Two support springs 23 are connected between the corresponding limiting arm 21 and the fixing plate 2. The support springs 23 tighten the two limiting arms 21, so that the limiting arms 21 can not only assist the cable 13 to be lowered and rolled up stably, but also squeeze the water off the cable when it is rolled up after contacting the water. In order to improve the water removal effect, the limiting wheel 22 can be made of water-absorbing material.

[0034] To achieve a better clamping and limiting effect, clamping grooves are formed on the rolling surface of the limiting wheel 22 along its rolling direction.

[0035] In the embodiment shown in Figure 4, a fixing ring 3 is fitted inside the limiting hole, and the inner ring surface of the fixing ring 3 is provided with bristles 31. When the cable is contaminated with mud in the channel, directly retracting the cable will not only easily reduce the service life of the cable, but also affect the flexibility of the cable after the mud dries on the surface of the cable. This will affect the winding stability of the winding post when the cable is rolled up and down. In the structure shown in Figure 4, when the cable passes through the fixing ring 3, the mud attached to its surface is brushed off by the bristles 31. This can not only extend the service life of the cable, but also avoid the impact of the dried mud on the stability of the cable when it is rolled up and down.

[0036] In the embodiment shown in Figure 4, in order to prevent the measuring instrument 14 from impacting the fixed ring 3 when it is pulled up, which would damage the measuring instrument 14 and affect the stability of the next measurement data, an annular rubber pad 6 is connected to the end of the fixed ring 3 near the ground, which can effectively buffer the impact between the measuring instrument 14 and the fixed ring 3.

[0037] In the embodiment shown in Figure 2, an elastic sealing sleeve is fitted over the buffer component. The two ends of the elastic sealing sleeve are connected to the fixing seat 19 and the housing 16, respectively. The elastic sealing sleeve can effectively prevent dirt in the channel from entering the gap of the buffer component and affecting the buffering effect of the buffer component.

[0038] As shown in Figure 5, in some measurement environments, uneven ground around the channel can cause the device to tilt when placed on the ground, affecting its stability and making it prone to movement during measurement. This can lead to collisions between the measuring instrument 14 and the channel, ultimately resulting in inaccurate measurement data. As shown in Figures 1 and 5, the side of the support plate 1 is provided with a horizontal plate. Multiple pre-drilled holes are made on the horizontal plate along its length, and multiple support plate fixing components are provided on the horizontal plate. Each support plate fixing component includes: an adjusting rod 4, an adjusting spring 42, and a limiting plate 41. The adjusting rod 4 is slidably inserted into the pre-drilled hole, and one end is connected to the limiting plate 41. The plate 41 has multiple nail feet 5 at one end. A spring 42 is set between the limiting plate 41 and the horizontal plate. When the device is set on uneven ground, the end of the adjusting rod 4 with nail feet 5 contacts the ground and the nail feet are fixed to the ground. When it encounters a raised ground, the adjusting rod 4 is lifted up and the adjusting spring is stretched. When it encounters a concave ground, the adjusting spring contracts, causing the adjusting rod 4 to move down, so that the nail feet 5 at the other end of the adjusting rod 4 are inserted into the concave ground. This adapts to the uneven surface structure and ensures the stability of the device during placement and measurement, thus ensuring that the measuring instrument 14 will not be impacted by the shaking of the device and the channel.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
