Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and more specifically, to a device for measuring the depth of rock and soil geological exploration and its method of use. Background Technology

[0002] Geotechnical investigation is the foundation of engineering design and construction. The accuracy of the investigation directly affects the safety and cost of the project, and may even affect its normal use and lifespan. Field construction is the vanguard of the investigation work, and its quality determines the overall quality of the investigation. Therefore, the depth measurement of geotechnical exploration boreholes is particularly crucial. For example, patent CN212432060U discloses a device for measuring the depth of geotechnical exploration, which includes a triangular mounting base, support frames hinged to the corners of the mounting base, a fixed pad at the lower end of each support frame, a protective shell located in the middle of the mounting base, a microprocessor located inside the protective shell, a distance sensor electrically connected to the microprocessor, an illumination lamp bead located around the distance sensor, and an adjustment shaft located at the connection between the protective shell and the mounting base. The distance sensor is an infrared ranging sensor. In this measuring device, the depth of the exploration borehole is detected by the infrared ranging sensor. However, when there is water in the exploration borehole, the reflection and refraction of the water surface will cause the infrared detector to fail to detect the bottom of the exploration borehole, resulting in inaccurate measurement of the depth of the exploration borehole and affecting subsequent exploration work. Summary of the Invention

[0003] The purpose of this invention is to provide a depth measurement device for rock and soil geological exploration and its usage method, which can measure not only the water depth but also the depth of the borehole when there is water in the borehole.

[0004] The objective of this invention is achieved as follows: a depth measurement device for rock and soil geological exploration, comprising a spool with a pull wire fixedly wound around it, the pull wire having graduations, and further comprising: a protective cover having a first cavity with its bottom surface recessed upwards, the protective cover having several water-permeable holes on its sidewalls, the protective cover being fixedly connected to the bottom end of the pull wire; a fixed conductive mechanism including an insulating rod, a first conductive plate, and a second conductive plate; a movable conductive mechanism including a support rod, a spring, and a conductive contact; an indicating mechanism including a battery, a first indicator light, and a second indicator light; a detection mechanism including a fixed rod, a telescopic rod, a float, and a plumb bob; and a waterproof mechanism for sealing the fixed conductive mechanism and the movable conductive mechanism.

[0005] Furthermore, the first conductive sheet and the second conductive sheet are fixed to the same side of the insulating rod, the first conductive sheet is disposed at the bottom of the second conductive sheet, the bottom of the first conductive sheet is spaced from the bottom of the insulating rod, the first conductive sheet is electrically connected to a first conductive wire, and the second conductive sheet is electrically connected to a second conductive wire.

[0006] Furthermore, the support rod is inverted "L" shape, and the top of the support rod is provided with a second cavity with the side wall recessed inward. The spring is fixed in the second cavity, and part of the conductive contact is slidably embedded in the second cavity. The other end of the spring is fixed to the conductive contact, and one end of the spring is electrically connected to a third wire. The conductive contact is coupled to the first conductive sheet and the second conductive sheet respectively.

[0007] Furthermore, one electrode of the battery is electrically connected to one end of the first indicator light and the second indicator light, respectively, and the other electrode of the battery is electrically connected to the third wire.

[0008] Furthermore, the other end of the first indicator light is electrically connected to the first wire, and the other end of the second indicator light is electrically connected to the second wire.

[0009] Furthermore, both the fixed rod and the telescopic rod are provided in pairs. The top end of the fixed rod is fixed to the bottom surface of the protective cover. The fixed rod has a third cavity with its bottom surface recessed upwards. The bottom of the third cavity has an opening, and a limiting ring is provided inside the opening. The telescopic rod slides into the third cavity. The top end of the telescopic rod has a limiting plate, which slides inside the third cavity. The limiting ring is used to prevent the limiting plate from detaching from the fixed rod. The telescopic rod has a limiting protrusion in the center.

[0010] Furthermore, the float is a cone-shaped body with its tip pointing downwards, the bottom end of the support rod is fixed to the top surface of the float, the two ends of the float are provided with mutually symmetrical sliding holes, the bottom of the telescopic rod slides through the sliding hole, the limiting protrusion is used to restrict the float from sliding upwards, the distance between the bottom of the limiting protrusion and the top surface of the float is less than the height of the first conductive sheet, and the bottom protruding end of the telescopic rod is fixed to the top surface of the hammer.

[0011] Furthermore, the waterproofing mechanism is a soft waterproof membrane with a hollow cylindrical structure. The waterproof membrane is positioned between the two fixed rods, with its top end fixed to the bottom surface of the protective cover and its bottom end fixed to the top surface of the floating block.

[0012] Furthermore, the first wire, the second wire, and the third wire are wound around the spool, and the battery, the first indicator light, and the second indicator light are located on the side wall of the spool.

[0013] The method of using the above-mentioned rock and soil geological exploration depth measurement equipment includes the following steps:

[0014] Confirm that the plumb bob and float are both hanging naturally.

[0015] Confirm that both the first and second indicator lights are off.

[0016] The detection mechanism is inserted into the axial exploration hole and connected to the protective cover.

[0017] When there is water at the bottom of the borehole, the float will push the moving conductive mechanism after contacting the water, and the conductive contact will contact the first conductive plate to trigger the first indicator light to light up. The limiting protrusion will restrict the float from continuing to move upward relative to the telescopic rod. At this time, the reading of the pull line corresponding to the borehole will be recorded as the water level depth.

[0018] When the plumb bob touches the bottom of the borehole, it pushes the telescopic rod upward and, through the float, pushes the moving conductive mechanism upward, causing the conductive contact to contact the second conductive plate and triggering the second indicator light to illuminate. At this time, the reading of the pull wire corresponding to the borehole is recorded as the depth of the borehole.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this device, the telescopic rod is slidably connected to the bottom of the fixed rod, the plumb bob is fixed to the bottom of the telescopic rod, and the float is slidably connected to the telescopic rod. When the device is lowered into the exploration hole, the float will push the conductive mechanism upward relative to the protective cover after contacting the water, so that the conductive contact contacts the first conductive plate and triggers the first indicator light to light up. Thus, the water depth can be obtained from the scale of the pull line. When the device is lowered to the bottom of the exploration hole, the plumb bob will push the telescopic rod and the float to continue to move upward relative to the protective cover after contacting the bottom of the hole, so that the conductive contact contacts the second conductive plate and triggers the second indicator light to light up. Thus, the hole depth can be obtained. Therefore, this device can measure not only the water depth but also the hole depth when there is water in the exploration hole.

[0021] 2. The waterproof membrane is placed between the two fixed rods. The top of the waterproof membrane is fixed to the bottom of the protective cover, and the bottom of the waterproof membrane is fixed to the top of the float. The protective cover, the waterproof membrane, and the float seal the insulating rod, the first conductive sheet, the second conductive sheet, the support rod, the spring, and the conductive contacts to prevent electronic components from coming into contact with water, thus ensuring the normal operation of the equipment.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a depth measurement device for rock and soil geological exploration includes a spool 1, a protective cover 2, a fixed conductive mechanism 3, a movable conductive mechanism 4, an indicating mechanism 5, a detection mechanism 6, and a waterproof mechanism 7.

[0030] A pull wire 11 is fixedly wound on the spool 1. The pull wire 11 is provided with scale lines, which are used to indicate the depth of the exploration hole. The scale values ​​increase sequentially from bottom to top.

[0031] The protective cover 2 has a first cavity with its bottom surface recessed upwards, and the side wall of the protective cover 2 has several water-permeable holes 21. The top of the protective cover 2 is fixed to the bottom of the pull wire 11.

[0032] The fixed conductive mechanism 3 includes an insulating rod 31, a first conductive sheet 32, and a second conductive sheet 33. The insulating rod 31 is made of insulating material and is vertically arranged. The first conductive sheet 32 ​​and the second conductive sheet 33 are fixed to the same side of the insulating rod 31 from bottom to top. The first conductive sheet 32 ​​and the second conductive sheet 33 are adjacent but do not contact each other. There is a gap between the first conductive sheet 32 ​​and the bottom end of the insulating rod 31. The first conductive sheet 32 ​​is electrically connected to a first wire 321, and the second conductive sheet 33 is electrically connected to a second wire 331.

[0033] The movable conductive mechanism 4 includes a support rod 41, a spring 42, and a conductive contact 43. The support rod 41 is inverted "L" shape, and the top of the support rod 41 has a second cavity with the side wall recessed inward. The spring 42 is disposed in the cavity, and one end of the spring 42 is fixed to the inner wall of the cavity. One end of the conductive contact 43 is slidably embedded in the second cavity, and the other end of the spring 42 is fixed to the insertion end of the conductive contact 43. Both the spring 42 and the conductive contact 43 are conductive. One end of the spring 42 is electrically connected to a third wire 421, which passes through the support rod 41.

[0034] The first conductor 321, the second conductor 331, and the third conductor 421 all pass through the top of the protective cover 2 and are wound alongside the pull wire 11 on the spool 1. The positions where the first conductor 321, the second conductor 331, and the third conductor 421 pass through the protective cover 2 are sealed with waterproof sealant.

[0035] The indicator mechanism 5 includes a battery 51, a first indicator light 52, and a second indicator light 53. One electrode of the battery 51 is electrically connected to one end of the first indicator light 52 and the second indicator light 53, respectively. The other end of the battery 51 is electrically connected to a third wire 421. The other end of the first indicator light 52 is electrically connected to a first wire 321, and the other end of the second indicator light 53 is electrically connected to a second wire 331. The battery 51, the first indicator light 52, and the second indicator light 53 are all located on the side wall of the spool 1.

[0036] The detection mechanism 6 includes a fixed rod 61, a telescopic rod 62, a float 63, and a hammer 64. Both the fixed rod 61 and the telescopic rod 62 have two identical rods. The top of the fixed rod 61 is fixed to the bottom surface of the protective cover 2. The fixed rod 61 has a third cavity 611 with its bottom surface recessed upwards. The bottom of the third cavity 611 has an opening, and a limiting ring 612 is installed inside the opening. The telescopic rod 62 slides into the third cavity 611. A limiting plate 621 is installed at the top of the telescopic rod 62 and slides within the third cavity 611. The limiting ring 612 is used to prevent the limiting plate 621 from detaching from the fixed rod. 61. A limiting protrusion 622 is provided in the center of the telescopic rod 62. The float 63 is a cone with its tip pointing downwards. The density of the float 63 is less than that of water. The bottom end of the support rod 41 is fixed to the top surface of the float 63. The two ends of the float 63 are provided with mutually symmetrical sliding holes 631. The bottom ends of the two telescopic rods 62 slide through the sliding holes 631. The limiting protrusion 622 is used to restrict the upward sliding of the float 63. The distance between the bottom of the limiting protrusion 622 and the top surface of the float 63 is less than the height of the first conductive sheet 32. The bottom end of the telescopic rod 62 is fixed to the top surface of the hammer 64. The weight of the hammer 64 is greater than the buoyancy of the float 63. Under the natural downward state of the float 63 and the hammer 64, the conductive contact 43 is located between the first conductive plate 32 and the bottom of the insulating rod 31. When the float 63 moves upward and fits against the limiting protrusion 622, the conductive contact 43 contacts the first conductive plate 32. When the hammer 64 is pushed upward, the conductive contact 43 contacts the second conductive plate 33. In this device, the telescopic rod 62 is slidably connected to the bottom of the fixed rod 61, the hammer 64 is fixed to the bottom of the telescopic rod 62, and the float 63 is slidably connected to the telescopic rod 62. When the device is lowered into the exploration hole, the float 63 will react with the water. Pushing the protective cover 2 upwards moves the conductive mechanism 4, causing the conductive contact 43 to contact the first conductive plate 32 and triggering the first indicator light 52 to illuminate. Thus, the water depth is obtained from the scale on the pull wire 11. When the device is lowered to the bottom of the exploration hole, the hammer 64 contacts the bottom of the hole and pushes the telescopic rod 62 and the float 63 to continue moving upwards relative to the protective cover 2, causing the conductive contact 43 to contact the second conductive plate 33 and triggering the second indicator light 53 to illuminate. Thus, the hole depth is obtained. Therefore, this device can measure not only the water depth but also the hole depth when there is water in the exploration hole.

[0037] The waterproof mechanism 7 is a soft waterproof membrane, which is a hollow cylindrical structure. The waterproof membrane is located between two fixed rods 61. The top of the waterproof membrane is fixed to the bottom surface of the protective cover 2, and the bottom surface of the waterproof membrane is fixed to the top surface of the float 63. The protective cover 2, the waterproof membrane, and the float 63 seal the insulating rod 31, the first conductive sheet 32, the second conductive sheet 33, the support rod 41, the spring 42, and the conductive contact 43 to prevent electronic components from coming into contact with water and to ensure the normal operation of the equipment.

[0038] This embodiment describes a method for measuring depth using a rock and soil geological exploration depth measuring device. The method involves the following steps:

[0039] Confirm that both the plumb bob 64 and the float 63 are hanging naturally.

[0040] Confirm that both indicator light 52 and indicator light 53 are off.

[0041] The detection mechanism 6, connected to the protective cover 2, is fed into the exploration hole through the spool 1;

[0042] When there is water at the bottom of the exploration hole, the float 63 pushes the moving conductive mechanism 4 after contacting the water and makes the conductive contact 43 contact the first conductive piece 32, triggering the first indicator light 52 to light up. The limiting protrusion 622 restricts the float 63 from continuing to move upward relative to the telescopic rod 62. At this time, the reading of the pull line 11 corresponding to the exploration hole is recorded as the water level depth.

[0043] When the hammer 64 touches the bottom of the exploration hole, the hammer 64 pushes the telescopic rod 62 to move upward and pushes the moving conductive mechanism 4 to move upward through the float 63, so that the conductive contact 43 contacts the second conductive plate 33 and triggers the second indicator light 53 to light up. At this time, the reading of the pull wire 11 corresponding to the exploration hole is recorded as the depth of the exploration hole.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
