Description

Technical Field

[0001] The utility model relates to the technical field of inclinometers, in particular to a borehole inclinometer. Background Art

[0002] An inclinometer is an instrument used to measure the apex angle and azimuth angle of engineering structures such as boreholes, foundation pits, foundation bases, walls, and dam slopes. It is divided into a portable inclinometer and a fixed inclinometer. The portable inclinometer is divided into a portable vertical inclinometer and a portable horizontal inclinometer, and the fixed inclinometer is divided into a single-axis and a biaxial inclinometer. The most widely used is the portable inclinometer. An inclinometer is an in-situ monitoring instrument that obtains the horizontal displacement by measuring the inclination angle of a borehole. The basic configuration of an inclinometer includes an inclinometer casing, an inclinometer probe, a control cable, and an inclinometer reader.

[0003] In order to pursue portability, the structure of the portable inclinometer is relatively simple. When performing inclinometer measurements, the cable is manually placed for both retraction and extension, posing a risk of the cable slipping out of the hand, causing the inclinometer tube to quickly drop in the borehole. If the borehole length is too short, the inclinometer tube will collide, and if the borehole length is too long, the connection part between the cable and the reader will be damaged. Therefore, we propose an inclinometer that can assist in lowering the inclinometer tube. Summary of the Utility Model

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0026] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indication will also change accordingly.

[0027] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0028] In the related art, in order to pursue portability, the structures of portable inclinometers are relatively simple. When performing inclinometer measurement work, the retraction and release of the cable are all manually placed, which poses a risk of the cable slipping out of the hand, resulting in the rapid dropping of the inclinometer tube in the borehole. If the borehole length is too small, the inclinometer tube will collide. If the borehole length is too large, the connection part between the cable and the reading instrument will be damaged.

[0029] To solve the problems in the related art to a certain extent, the embodiments of the present application provide a borehole inclinometer. When in use, only the fixing plate 15 with the connecting plate 14 needs to be pulled out from the base 11, and then the cable passes through between the retraction and release wheels 16 of the fixing plate 15.

[0030] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0031] Combined with Figures 1-4, an embodiment of the present application provides an inclinometer, including an inclinometer device 1; the inclinometer device 1 includes: an inclinometer mechanism 12 is provided on the top of the base 11; a chute 13 is opened on the outer wall of the base 11; a connecting plate 14 is arranged inside the chute 13; a fixing plate 15 is arranged at one end of the connecting plate 14; a winding wheel 16 is arranged between the fixing plates 15 and is rotatably connected to the fixing plates 15; a handle 17 is arranged on the outer wall of the fixing plate 15 and is connected to the winding wheel 16.

[0032] When in use, first pull out the connecting plate 14 equipped with the fixing plate 15 and the winding wheel 16 from the chute 13 of the base 11, so that the winding wheel 16 is located directly above the drill hole. Then, the cable passes through the winding wheel 16 and is respectively connected to the inclinometer mechanism 12 and the inclinometer tube. The winding wheel 16 squeezes the cable, generating great friction, so that the inclinometer tube will not drag the cable and fall. Then, rotate the winding wheel to slowly insert the inclinometer tube and the cable into the drill hole. After use, push the connecting plate 14 back into the chute 13 of the base 11 for storage.

[0033] Specifically, the inclinometer mechanism 12 and the inclinometer tube are existing technical means, and their detailed structures are not shown in the drawings.

[0034] In some embodiments, a first fixing block 18 is arranged on the outer wall of the fixing plate 15, and rollers 181 are arranged at the bottom of the first fixing block 18 and the connecting plate 14. By installing the rollers 181 at the bottom of the first fixing block 18 and the connecting plate 14, the fixing plate 15 is further facilitated to move.

[0035] In some embodiments, a groove 131 for cooperating with the roller 181 is opened on the inner wall of the chute 13. The setting of the groove 131 enables the roller 181 to smoothly move into the base 11.

[0036] In some embodiments, an auxiliary component 2 is arranged on the inclinometer device 1. The auxiliary component 2 includes: a pin 21 penetrates through the handle 17; a fixing hole 22 is opened on the outer wall of the fixing plate 15; a limiting block 23 is arranged on the outer wall of the pin 21. After the handle 17 rotates, the pin 21 is inserted into the fixing hole 22 of the fixing plate 15 to fix the handle and prevent the winding wheel 16 from rotating continuously.

[0037] In some embodiments, a rubber sleeve 171 is arranged on the outer wall of the handle 17. The setting of the rubber sleeve 171 enables the handle 17 to be used better.

[0038] In some embodiments, a second fixing block 24 is arranged on the outer wall of the base 11, and a ground nail 25 penetrates through the second fixing block 24. The ground nail 25 penetrates through the second fixing block 24 and is inserted into the ground, which can better fix the base 11.

[0039] In some embodiments, magnetic attraction blocks 26 which cooperate with each other are arranged on the outer side walls of the fixing plate 15 and the base 11. The fixing plate 15 and the base 11 are adsorbed and fixed through the magnetic attraction blocks 26 to prevent the fixing plate 15 and the connecting plate 14 from sliding outwards.

[0040] In some embodiments, an auxiliary hole 27 is arranged at the top between the fixing plate 15 and the winding and unwinding wheel 16. The auxiliary hole 27 is provided to enable the cable to pass through between the winding and unwinding wheels 16 better.
