Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering investigation technology, specifically to a geotechnical engineering investigation borehole water level measuring device. Background Technology

[0002] From an engineering and construction perspective, soil and rock are a collective term for any type of rock and soil that makes up the Earth's crust. Soil and rock can be further divided into five categories: hard (hard rock), medium-hard (soft rock), weakly connected, loose and unconnected, and those with special composition, structure, state, and properties. In geological exploration, drilling equipment is used to drill a small-diameter, deep cylindrical hole into the ground, also known as a well. Water level refers to the elevation of the free water surface of a water body above a fixed base surface, and its unit is meters. Borehole water level measurement is the measurement of the water level in the borehole to provide data for subsequent engineering.

[0003] The existing method involves a person holding an I-beam reel and moving it into the drilling area. The person then places the water level detection probe on the I-beam reel into the borehole. As the I-beam reel rotates, the wound graduated cable extends upwards. During the extension or retraction of the graduated cable, the person needs to provide partial support to ensure the cable descends vertically. Alternatively, a support roller can be fixed to the upper surface of the drilling area, and the graduated cable can be placed on the support roller to provide support, allowing the water level detection probe and the graduated cable to descend vertically for water level detection.

[0004] While the existing technologies described above allow for manual support and guidance of the graduated line rope using manual methods or support rollers, manual support causes friction between the rope and the operator's hands as the rope descends, resulting in skin abrasions. Furthermore, the guiding effect is poor. Using support rollers requires personnel to carry and install the rollers on the upper surface of the borehole, necessitating manual installation and removal – a process that is overly cumbersome and inefficient. Utility Model Content

[0005] In view of this, the present invention provides a water level measuring device for boreholes in geotechnical engineering exploration. The present invention can avoid the need for manual support of the scale line or the use of auxiliary tugs for support, thereby improving work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a borehole water level measuring device for geotechnical engineering exploration, including a triangular base one and a triangular base two. An I-beam wheel is fixedly mounted between the sides of the triangular base one and the triangular base two via a rotating column. A graduated rope is wound around the I-beam wheel, and a water level detector is mounted at the end of the graduated rope. Two support bars are vertically mounted on the bottom of both the triangular base one and the triangular base two. A fixing rod is mounted on the top of each support bar, and an auxiliary support assembly is mounted on the fixing rod. The auxiliary support assembly includes an adjusting groove, which is located within the fixing rod, and a sliding mechanism is installed within each adjusting groove. Both the rod and the sliding rod are equipped with fixing strips at their ends, and support seats are set between the side ends of the fixing strips. Auxiliary support rollers are set on the support seats. The triangular support base is moved to the drilling area of ​​the geotechnical engineering exploration, and then the position of the sliding rod in the adjustment groove is adjusted so that the auxiliary support roller slides to the upper surface of the borehole. The I-beam wheel rotates clockwise, and the scale line rope is extended accordingly. The auxiliary support roller provides support for the scale line rope. The water level detector enters the borehole under its own gravity, which facilitates the detection. After the measurement is completed, the I-beam wheel is rotated counterclockwise to wind the scale line rope and retrieve the water level detector, completing one water level measurement.

[0007] The auxiliary support assembly also includes multiple threaded holes all disposed on the sliding rod, and a threaded rod 1 is rotatably disposed on the upper surface of the fixed rod. The threaded rod 1 is threaded to the threaded hole. A drive button 1 is disposed on the top of the sliding rod, and the side end of the drive button 1 is connected to one end of the threaded rod 1; that is, the drive button 1 provides drive for the threaded rod 1, so that the threaded rod 1 rotates.

[0008] A drive rotation assembly is provided on the side end of the triangular base. The drive rotation assembly includes a drive column provided on the side end of the triangular base, and one end of the drive column is connected to the rotating column; that is, the drive column is connected to the rotating column, so that the drive column can drive the rotating column to rotate.

[0009] The drive rotation assembly also includes a drive disk disposed at the end of the drive column; that is, the drive disk is used to drive the drive column, thereby causing the drive column to rotate.

[0010] The drive rotation assembly also includes a rotating gear mounted on the drive column, a fixed block on one side of the triangular base, a threaded rod rotatably mounted on the fixed block, a support block rotatably mounted at the end of the threaded rod, a limit tooth on the upper surface of the support block, and a drive button 2 at the bottom of the fixed block. The side end of the drive button 2 is connected to one end of the threaded rod 2. That is, the rotation of the threaded rod 2 can drive the limit tooth to move upward, thereby causing the limit tooth to enter between the rotating gears, thus limiting the rotation of the rotating gears and stopping the drive column from rotating.

[0011] The drive rotation assembly also includes a guide groove on one side of the triangular base, and a slider is provided on the side of the guide groove. The slider is connected to the side of the support block; that is, the support block can slide up and down in the guide groove.

[0012] A handle is provided between the upper surfaces of the fixed rod; this facilitates the movement of the parts below the handle by personnel.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. First, by rotating the threaded rod, the threaded rod is disengaged from the threaded hole on the fixed rod, making it easier for the sliding rod to slide within the fixed rod. This indirectly allows the auxiliary support roller to be moved to the upper surface of the drilling area. Then, the threaded rod is rotated again to re-enter the threaded hole, thereby limiting the sliding rod. At the same time, the graduated string can be placed on the auxiliary support roller, which provides support and guidance for the graduated string.

[0015] 2. The drive button is connected to one end of the threaded rod. The drive button can rotate the threaded rod on the support block, causing the threaded rod to rotate and move upward on the support block. This rotation can move the limiting teeth upward, causing the limiting teeth to enter between the teeth on the rotating gear, thereby limiting the drive column and restricting its rotation, thus stopping the H-beam reel from feeding or retracting the line.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] like Figure 1-4As shown: This embodiment provides a borehole water level measuring device for geotechnical engineering exploration, including a triangular base 100 and a triangular base 2 101. A bobbin 103 is fixedly mounted between the sides of the triangular base 100 and the bobbin 2 101 via a rotating column 108. The rotating columns 108 on both sides of the bobbin 103 are welded together, and then the rotating columns 108 are installed in bearings on the sides of the triangular base 100 and the bobbin 2 101, so that the rotating columns 108 can carry the bobbin 103 to rotate between the sides of the triangular base 100 and the bobbin 2 101. A graduated cord 106 is wound around the I-beam reel 103, and a water level detector 107 is attached to the end of the graduated cord 106. When the I-beam reel 103 rotates counterclockwise, the graduated cord 106 is wound around it. When the I-beam reel 103 rotates clockwise, the cord 106 is extended, allowing the water level detector 107 to enter the through hole in the geotechnical engineering borehole under its own weight, thus facilitating the measurement of the water level in the borehole. Two vertical support bars 10 are each vertically mounted on the bottom of the triangular base 100 and the triangular base 2 101. 4. Two support bars 104 are fixedly installed on the triangular base 100 and the triangular base 2 101 by welding. Each support bar 104 has a fixing rod 105 at its top. The fixing rod 105 is fixedly installed on the triangular base 100 and the triangular base 2 101 by welding, thus providing support for the fixing rod 105. An auxiliary support assembly 200 is provided on the fixing rod 105. The auxiliary support assembly 200 includes adjusting grooves, each set within the fixing rod 105. Each adjusting groove contains a sliding rod 203, and the ends of the sliding rods 203 are each... There is a fixing bar 205, and a support base 206 is provided between the side ends of the fixing bar 205. An auxiliary support roller 207 is provided on the support base 206. When the triangular base one 100 and the triangular base two 101 move close to the drilling area, the sliding rod 203 extends in the adjustment groove, so that the sliding rod 203 carries the auxiliary support roller 207 on the support base 206 to slide to the upper surface of the drilling hole. Then, by placing the scale line 106 into the auxiliary support roller 207, the manual support of the scale line 106 or the support of the auxiliary support roller is avoided, thereby improving work efficiency.

[0026] like Figure 2 As shown,

[0027] The auxiliary support assembly 200 also includes a plurality of threaded holes 204 all disposed on the sliding rod 203. The upper surface of the fixed rod 105 is rotatably provided with a threaded rod 202, which is threaded to the threaded hole 204. The top of the sliding rod 203 is provided with a drive button 201, and the side end of the drive button 201 is connected to one end of the threaded rod 202.

[0028] Firstly, the threaded rod 202 can be indirectly rotated by rotating the drive button 201. During the rotation of the threaded rod 202, the threaded rod 202 can enter one of the multiple threaded holes 204, thereby limiting and supporting the sliding rod 203, thus preventing the sliding rod 203 from sliding within the fixed rod 105.

[0029] like Figure 2 As shown,

[0030] A drive rotation assembly 300 is provided on the side end of the triangular base 100. The drive rotation assembly 300 includes a drive column 302 provided on the side end of the triangular base 100. The drive column 302 is connected to one end of the rotating column 108, so that the drive column 302 rotates and can carry the rotating column 108 to rotate.

[0031] The drive rotation assembly 300 also includes a drive disk 301 disposed on the end of the drive column 302;

[0032] First, the operator can drive the drive disc 301 to rotate. Indirectly, the drive disc 301 can carry the drive column 302 to rotate. During the rotation, the drive column 302 can carry the rotating column 108 to rotate, so that the I-beam reel 103 can take in or let out the graduated line 106.

[0033] like Figure 2 As shown,

[0034] The drive rotation assembly 300 also includes a rotating gear 303 mounted on the drive column 302, and a fixing block 304 on the side end of the triangular base 100. The fixing block 304 is fixedly mounted on the triangular base 100 by welding. A threaded rod 307 is rotatably mounted on the fixing block 304, and a support block 305 is rotatably mounted at the end of the threaded rod 307. A bearing is mounted at the end of the threaded rod 307 and is installed inside the support block 305. A limit is provided on the upper surface of the support block 305. The bottom of the fixing block 304 is provided with a second drive button 308. The side end of the second drive button 308 is connected to one end of the second threaded rod 307. The second drive button 308 is connected to the end of the first threaded rod 202. The second drive button 308 can carry the second threaded rod 307 to rotate on the support block 305, so that the second threaded rod 307 rotates and moves upward on the support block 305. It can carry the limiting tooth to move upward, so that the limiting tooth enters between the teeth on the rotating gear 303, thereby limiting the drive column 302 and restricting the rotation of the drive column 302.

[0035] like Figure 2 As shown,

[0036] The drive rotation assembly 300 also includes a guide groove 306 provided on the side end of the triangular base 100. A slider is provided on the side end of the guide groove 306. The side end of the slider is connected to the side end of the support block 305, thereby providing guidance for the movement of the support block 305.

[0037] like Figure 2 As shown,

[0038] A handle 102 is provided between the upper surfaces of the fixing rods 105. There are two fixing rods 105, and the handle 102 is installed between the upper surfaces of the two fixing rods 105, so as to lift the parts below the fixing rods 105, thereby facilitating the transfer of the triangular base 100 and the triangular base 2 101 by personnel.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
