Description

Technical Field

[0001] This invention relates to the field of geological measuring instruments, specifically a geological measuring instrument for use in the field of geological engineering. Background Technology

[0002] The field of geological engineering primarily focuses on engineering problems related to geological surveys, mineral resource exploration and prospecting, and the geological structure and background of major projects. The purpose of geotechnical investigation is to provide engineering geological basis for the foundation design and construction of the proposed building during the construction drawing stage. Based on the engineering characteristics of the proposed building and the engineering geological conditions of the foundation soil, it proposes solutions for the utilization, remediation, and modification of the site's foundation soil, and conducts technical and economic analysis and demonstration. The accuracy of the investigation directly affects the safety, cost, and lifespan of the project. Surveyors often need to conduct geological surveys in the field. During the investigation, it is necessary to use survey equipment to measure the depth of the geological survey, thereby improving the accuracy of geotechnical engineering surveys.

[0003] Existing geological surveying equipment makes it difficult to clean drill rods after geotechnical engineering surveys, resulting in mud adhering to the surface of the drill rods. Prolonged exposure to this mud poses a risk of corrosion and leads to a shorter service life and poor performance.

[0004] Therefore, we propose a geological measuring instrument for use in the field of geological engineering. Summary of the Invention

[0005] The purpose of this invention is to provide a geological measuring instrument for use in the field of geological engineering, which has the advantage of cleaning drill pipes and solves the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a geological measuring instrument for use in the field of geological engineering, comprising a base, wherein columnar rods are fixedly connected to the base near both side edges, and rectangular sliders for reciprocating movement are slidably connected to the two columnar rods near the upper outer contour of the top, wherein the rectangular sliders have rectangular through holes, and the bottom of the rectangular sliders penetrates to the inner wall of the rectangular through holes and is rotatably connected to a drilling rod for drilling soil, wherein one end of the drilling rod near the rectangular through holes is driven to rotate by a power mechanism, and a circular through hole is provided on the base corresponding to the position of the drilling rod, wherein the drilling rod penetrates to the inner wall of the circular through hole and is movably connected, and a cleaning mechanism for cleaning the drilling rod is also provided on the columnar rods.

[0007] Preferably, the cleaning mechanism includes two cylindrical rods, each with a fixed plate fixedly connected to its top. A cylindrical shell is fixedly connected to the opposite sides of the two fixed plates. A water tank for storing cleaning fluid is fixedly connected to the top of the cylindrical shell. A drain pipe for discharging the cleaning fluid from the cylindrical shell is penetrated and fixedly connected to the outer contour of the cylindrical shell near the water tank. A nozzle for spraying the cleaning fluid onto the drill rod for cleaning is fixedly connected to the end of the drain pipe near the base.

[0008] Preferably, the cleaning mechanism further includes a movable rod that is slidably connected through and limited at the center of the bottom of the cylindrical housing, and a piston plate for sucking in or discharging cleaning liquid is fixedly connected to the top of the movable rod, the piston plate moving up and down and reciprocating on the inner wall of the cylindrical housing.

[0009] Preferably, the cylindrical shell and the water storage tank are connected by a water inlet pipe that fills the cleaning liquid in the water storage tank into the inner wall of the cylindrical shell. The inner wall of the water inlet pipe is fixedly connected with a one-way water inlet valve. The inner wall of the drain pipe near the cylindrical shell is fixedly connected with a one-way drain valve that discharges the cleaning liquid in the cylindrical shell.

[0010] Preferably, a first return spring that pushes the rectangular slider to move axially upward is movably connected to the outer contour of the cylindrical rod near the base. The two ends of the first return spring are fixedly connected to the rectangular slider and the base. There are two first return springs in total, and the two first return springs are evenly distributed on the two cylindrical rods respectively.

[0011] Preferably, the rectangular slider is further provided with an auxiliary mechanism for viewing the drilling depth of the drill rod. The auxiliary mechanism includes a connecting plate fixedly connected to one end of the rectangular slider, a rectangular block fixedly connected to the end of the connecting plate away from the rectangular slider, a groove on the rectangular block, a sliding rod slidably connected to the inner wall of the groove, a connecting rod fixedly connected to the end of the sliding rod away from the rectangular block, and a scale for viewing the drilling depth of the drill rod fixedly connected to one side of the connecting rod.

[0012] Preferably, the auxiliary mechanism further includes a limiting rod that passes through and slides on the connecting rod near the edges of both ends. The limiting rod is placed horizontally and symmetrically with the scale. Both ends of the limiting rod are fixedly connected to a support plate. The bottoms of the two support plates are fixedly connected to the base. The end of the scale away from the connecting rod passes through one of the support plates and is slidably connected for limiting.

[0013] Preferably, a second reset spring is movably connected to the outer contour of the scale to push the connecting rod to reset, and the two ends of the second reset spring are fixedly connected to the connecting rod and the support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The power mechanism drives the drill rod to reciprocate along a fixed axis, allowing it to drill more effectively into the soil. As the drill rod moves towards the soil, it penetrates deeper, causing a rectangular slider to move downwards along the cylindrical rod. A movable rod on the rectangular slider pulls the movable rod and piston plate downwards synchronously. When the piston plate moves downwards, positive pressure is applied to the inner wall of the cylindrical shell near the water tank, closing the one-way drain valve and opening the one-way inlet valve. This allows the piston plate to draw cleaning fluid from the water tank into the cylindrical shell. As the drill rod moves away from the soil... This causes the rectangular slider to move axially upwards on the cylindrical rod. The upward movement of the rectangular slider pushes the moving rod and piston plate upwards synchronously. When the piston plate moves upwards, and the inner wall of the cylindrical shell near the water tank is under negative pressure, the one-way drain valve opens and the one-way inlet valve closes. This allows the cleaning fluid inside the cylindrical shell to be discharged into the drain pipe through the one-way drain valve. The nozzles on the drain pipe spray the cleaning fluid onto the drill rod for rinsing, effectively washing away the mud and debris adhering to the drill rod, thus extending its service life.

[0016] As the rectangular slider moves the rectangular block downwards, the slide rod slides within the groove. As the drilling depth of the drill rod increases, the connecting rod pushes the second return spring to move horizontally to the left to the same scale. This allows for better monitoring of the drilling depth of the drill rod in the soil. When the drill rod completes its drilling work and moves upwards to reset, the rectangular slider moves the rectangular block upwards, causing the slide rod to move the connecting rod to the right. The second return spring on the scale allows for better pushing of the connecting rod to move horizontally to the right to reset.

[0017] The combined use of the above structures solves the problem that geological surveying equipment has difficulty cleaning drill pipes, resulting in mud adhering to the surface of the drill pipes, which poses a risk of corrosion if left for a long time and leads to a shorter service life of the drill pipes.

[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] Example 1

[0030] Please see Figures 1 to 9This invention provides a technical solution: a geological measuring instrument for use in the field of geological engineering, including a base 1, on which columnar rods 2 are fixedly connected near the two side edges. Rectangular sliders 3, which move up and down and back and forth, are slidably connected to the upper limit of the outer contour of the two columnar rods 2 near the top. A rectangular through hole 31 is opened on the rectangular slider 3. The bottom of the rectangular slider 3 passes through the inner wall of the rectangular through hole 31 and is rotatably connected to a drilling rod 4 for drilling the soil. One end of the drilling rod 4 near the rectangular through hole 31 is driven to rotate by a power mechanism. A circular through hole 101 is opened on the base 1 at the position corresponding to the drilling rod 4. The drilling rod 4 passes through the inner wall of the circular through hole 101 and is movably connected. A cleaning mechanism for cleaning the drilling rod 4 is also provided on the columnar rods 2.

[0031] The cleaning mechanism includes two cylindrical rods 2, each with a fixed plate 6 fixedly connected to its top. The two fixed plates 6 are fixedly connected to a cylindrical shell 7 on their opposite sides. A water tank 10 for storing cleaning fluid is fixedly connected to the top of the cylindrical shell 7. A drain pipe 11 for discharging the cleaning fluid from the cylindrical shell 7 is fixedly connected through the outer contour of the cylindrical shell 7 near the water tank 10. A nozzle 112 for spraying cleaning fluid onto the drill rod 4 for cleaning is fixedly connected to the end of the drain pipe 11 near the base 1.

[0032] The cleaning mechanism also includes a movable rod 8 that is slidably connected through and limited at the center of the bottom of the cylindrical housing 7. A piston plate 9 for sucking in or discharging cleaning liquid is fixedly connected to the top of the movable rod 8. The piston plate 9 moves up and down and back and forth on the inner wall of the cylindrical housing 7.

[0033] A water inlet pipe 12 is fixedly connected to the opposite side of the cylindrical shell 7 and the water storage tank 10, which fills the cleaning liquid in the water storage tank 10 into the inner wall of the cylindrical shell 7. A one-way water inlet valve 121 is fixedly connected to the inner wall of the water inlet pipe 12. A one-way drain valve 111 is fixedly connected to the inner wall of the drain pipe 11 near the end of the cylindrical shell 7, which discharges the cleaning liquid in the cylindrical shell 7.

[0034] A first return spring 5 is movably connected to the outer contour of the cylindrical rod 2 near the base 1 to push the rectangular slider 3 to move axially upward. The two ends of the first return spring 5 are fixedly connected to the rectangular slider 3 and the base 1. There are two first return springs 5 ​​in total, and the two first return springs 5 ​​are evenly distributed on the two cylindrical rods 2 respectively.

[0035] By setting the base 1, the cylindrical rod 2 can be placed more stably on the base 1. The rectangular slider 3 set on the cylindrical rod 2, and the first return spring 5 set on the cylindrical rod 2, make it easier for the rectangular slider 3 to move up and down and back and forth on the cylindrical rod 2. The rectangular through hole 31 opened on the rectangular slider 3, and the drilling rod 4 set on the rectangular slider 3, are driven by the power mechanism to rotate, so that the drilling rod 4 rotates on the rectangular slider 3 on a fixed axis. The circular through hole 101 set on the base 1 allows the drilling rod 4 to drill into the soil better. The fixing plate 6 set on the cylindrical rod 2 makes the cylindrical shell 7 placed more stably on the fixing plate 6. The water storage tank 10 set on the cylindrical shell 7 allows the cleaning liquid to be better stored in the inner wall of the water storage tank 10. The drain pipe 11 set on the cylindrical shell 7, and the nozzle 112 set on the drain pipe 11, allows the cleaning liquid to be sprayed and cleaned on the drilling rod 4 through the nozzle 112.

[0036] The movable rod 8 on the cylindrical housing 7 moves axially back and forth. The piston plate 9 on the movable rod 8 moves axially back and forth in sync with the movable rod 8, allowing the piston plate 9 to better draw in or discharge the cleaning liquid. The inlet pipe 12 on the cylindrical housing 7 and the water tank 10 allows the cylindrical housing 7 to draw in the cleaning liquid from the water tank 10. The one-way inlet valve 121 on the inlet pipe 12 moves axially downward with the piston plate 9, allowing the one-way inlet valve 121 to better control the amount of cleaning liquid drawn into the water tank 10 by the cylindrical housing 7. The one-way drain valve 111 on the drain pipe 11 moves axially upward with the piston plate 9, allowing the one-way drain valve 111 to more easily discharge the cleaning liquid from the inner wall of the cylindrical housing 7.

[0037] The aforementioned structure, through a power mechanism, drives the drill rod 4 to reciprocate along a fixed axis, allowing the drill rod 4 to drill more effectively into the soil. As the drill rod 4 moves towards the soil and penetrates it, the rectangular slider 3 moves downward axially on the cylindrical rod 2. The movable rod 8 on the rectangular slider 3 pulls the movable rod 8 and the piston plate 9 downward axially in sync. When the piston plate 9 moves downward, and the inner wall of the cylindrical shell 7 near the water storage tank 10 is under positive pressure, the one-way drain valve 111 is closed, and the one-way inlet valve 121 is open. This allows the piston plate 9 to draw the cleaning fluid from the water storage tank 10 into the cylindrical shell 7. As the drill rod 4 moves away from the soil... The rectangular slider 3 moves upward axially on the cylindrical rod 2, and the upward movement of the rectangular slider 3 pushes the moving rod 8 and the piston plate 9 to move upward axially in sync. When the piston plate 9 moves upward, the inner wall of the cylindrical shell 7 near the water storage tank 10 is under negative pressure, so the one-way drain valve 111 is open and the one-way inlet valve 121 is closed. This allows the cleaning fluid in the cylindrical shell 7 to be discharged into the drain pipe 11 through the one-way drain valve 111. The nozzle 112 installed on the drain pipe 11 sprays the cleaning fluid onto the drill rod 4 for rinsing, which can better wash off the mud and sludge adhering to the drill rod 4, thereby extending the service life of the drill rod 4.

[0038] Example 2

[0039] Building upon Example 1, the following is a further step:

[0040] The rectangular slider 3 is also equipped with an auxiliary mechanism for viewing the drilling depth of the drill rod 4. The auxiliary mechanism includes a connecting plate 13 fixedly connected to one end of the rectangular slider 3, a rectangular block 14 fixedly connected to the end of the connecting plate 13 away from the rectangular slider 3, a groove 15 opened on the rectangular block 14, a sliding rod 16 slidably connected to the inner wall of the groove 15, a connecting rod 17 fixedly connected to the end of the sliding rod 16 away from the rectangular block 14, and a scale 20 for viewing the drilling depth of the drill rod 4 fixedly connected to one side of the connecting rod 17.

[0041] The auxiliary mechanism also includes a limiting rod 18 that passes through and slides on the connecting rod 17 near the edges of both ends. The limiting rod 18 and the scale 20 are placed horizontally and symmetrically. Both ends of the limiting rod 18 are fixedly connected to a support plate 19. The bottom of the two support plates 19 are fixedly connected to the base 1. The end of the scale 20 away from the connecting rod 17 passes through one of the support plates 19 and is limited and slidably connected.

[0042] A second reset spring 21 is movably connected to the outer contour of the scale 20 to push the connecting rod 17 to reset. The two ends of the second reset spring 21 are fixedly connected to the connecting rod 17 and the support plate 19.

[0043] The rectangular block 14 on the rectangular slider 3 is placed more stably on the connecting plate 13. The sliding groove 15 on the rectangular block 14 and the sliding rod 16 on the sliding groove 15 limit the sliding of the sliding rod 16 within the inner wall of the sliding groove 15. The connecting rod 17 on the sliding rod 16 and the scale 20 on the connecting rod 17 move horizontally back and forth with the rectangular slider 3. The limiting rod 18 on the connecting rod 17 limits the horizontal movement of the connecting rod 17. The support plate 19 on the limiting rod 18 allows the limiting rod 18 to be placed more stably on the support plate 19. The second return spring 21 on the scale 20 pushes the connecting rod 17 to return to its original position more easily as the rectangular block 14 moves upward to return to its original position.

[0044] In the above structure, as the rectangular slider 3 drives the rectangular block 14 to move downwards synchronously, the slide rod 16 slides within the inner wall of the groove 15. As the drilling depth of the drill rod 4 increases, the connecting rod 17 pushes the second return spring 21 to move horizontally to the left to the same scale, thus allowing for better viewing of the drilling depth of the drill rod 4 in the soil. When the drill rod 4 completes its drilling work and moves upwards to reset, the rectangular slider 3 drives the rectangular block 14 to move upwards synchronously, causing the slide rod 16 to drive the connecting rod 17 to move to the right. The second return spring 21 on the scale 20 allows the second return spring 21 to better push the connecting rod 17 to move horizontally to the right to reset.

[0045] This further enables the geological surveying device to clean the drill pipe and extend its service life, making it superior to traditional products.

[0046] Working Principle: This geological measuring instrument, used in geological engineering, operates by driving a drill rod 4 to reciprocate along a fixed axis via a power mechanism. This allows the drill rod 4 to drill more effectively into the soil. As the drill rod 4 moves towards and into the soil, the rectangular slider 3 moves downward axially on the cylindrical rod 2. A moving rod 8 on the rectangular slider 3 pulls the moving rod 8 and piston plate 9 downward axially in sync. When the piston plate 9 moves downward, and the inner wall of the cylindrical housing 7 near the water storage tank 10 is under positive pressure, the one-way drain valve 111 is closed, and the one-way inlet valve 121 is open. This allows the piston plate 9 to draw the cleaning fluid from the water storage tank 10 into the cylindrical housing 7. Simultaneously, the drill rod... 4. When moving away from the soil, the rectangular slider 3 moves upward axially on the cylindrical rod 2. The upward movement of the rectangular slider 3 pushes the moving rod 8 and the piston plate 9 to move upward axially in sync. When the piston plate 9 moves upward, the inner wall of the cylindrical shell 7 near the water storage tank 10 is under negative pressure, so the one-way drain valve 111 is open and the one-way inlet valve 121 is closed. This allows the cleaning liquid in the cylindrical shell 7 to be discharged into the drain pipe 11 through the one-way drain valve 111. The nozzle 112 installed on the drain pipe 11 sprays the cleaning liquid onto the drill rod 4 for rinsing, which can better wash off the mud and sludge adhering to the drill rod 4, thereby extending the service life of the drill rod 4.

[0047] This further enables the geological surveying device to clean the drill pipe and extend its service life, making it superior to traditional products.

At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.
