Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A borehole water level measuring instrument for geotechnical engineering investigation includes:

[0026] The instrument body includes an instrument 1 and a water level sensor 12. The surface of the instrument 1 is electrically connected to a connecting wire 11. The water level sensor 12 is electrically connected to the instrument 1 through the connecting wire 11. With the connection between the instrument 1 and the connecting wire 11, the connection between the connecting wire 11 and the water level sensor 12 is achieved through the action of the connecting wire 11. Both the instrument 1 and the water level sensor 12 are existing products, and their principles are existing technologies, which will not be described in detail here.

[0027] The storage mechanism includes a placement platform 2, which is fixedly connected to the surface of the instrument 1. A support plate 21 is fixedly connected to the surface of the placement platform 2, and a backing plate 22 is elastically connected to the surface of the support plate 21. A placement plate 23 is fixedly connected to the outer surface of the placement platform 2, and a binding strap 24 is provided on the surface of the placement plate 23. A connecting frame 25 is fixedly connected to the surface of the placement plate 23, and a screw 26 is threadedly connected to the surface of the connecting frame 25. A backing plate 27 is movably connected to the bottom end of the screw 26. Through the connection of the placement platform 2 and the placement plate 23, and under the connection of the binding strap 24 and the connecting frame 25, the connection of the screw 26 and the backing plate 27, through the action of the backing plate 27, achieves the effect of controlling the length of the binding strap 24, thereby achieving the binding and support effect of the connecting wire 11 on the placement plate 23.

[0028] Furthermore, the connecting wire 11 is wound around the placement platform 2 via the instrument 1, and the water level sensor 12 is engaged and connected to the surface of the placement platform 2 via the support plate 21 and the abutment plate 22. Through the connection of the instrument 1 and the connecting wire 11, the placement platform 2 can support and store the winding connecting wire 11. Through the connection of the support plate 21 and the abutment plate 22, the abutment plate 22 and the water level sensor 12 are in contact, thus achieving the effect of placing and storing the water level sensor 12 on the placement platform 2.

[0029] Furthermore, the placement plates 23 are connected in two opposing groups on the outer surface of the placement platform 2. One end of the binding strap 24 is fixedly connected to the surface of the placement plate 23, and the other end of the binding strap 24 is connected through the connecting frame 25. Through the connection between the placement platform 2 and the placement plate 23, and under the connection between the placement plate 23 and the binding strap 24, the binding and support effect of the connecting wire 11 on the placement plate 23 is achieved, thereby achieving its storage effect.

[0030] Furthermore, the screw 26 passes through the connecting frame 25 and the abutment plate 27 and is rotatably connected. A cone block is fixedly connected to the bottom end of the abutment plate 27, and the cone block abuts against the surface of the restraint strap 24 through the abutment plate 27. Through the connection of the connecting frame 25 and the screw 26, and the connection of the screw 26 and the abutment plate 27, the connection between the abutment plate 27 and the cone block is realized, thereby achieving the effect of adjusting the length of the restraint strap 24 on the placement plate 23, and improving the application range and performance of the restraint strap 24 in storing and restraining the connecting wire 11.

[0031] Furthermore, the surface of the instrument 1 is provided with a positioning mechanism, which includes a support frame 3 and a slide groove 31. The slide groove 31 is formed on the surface of the instrument 1, and the support frame 3 is slidably connected to the inside of the slide groove 31. A connecting groove 33 is formed inside the support frame 3, and a block 32 is slidably connected to the inner side of the connecting groove 33. A support spring 34 is fixedly connected to the surface of the block 32. Through the connection between the instrument 1 and the slide groove 31, the position of the support frame 3 on the instrument 1 can be adjusted under the sliding connection between the support frame 3 and the slide groove 31.

[0032] Furthermore, the support frame 3 consists of two parts: one part is wheel-shaped, and the other part is T-shaped rod-shaped. The cross-section of the slide groove 31 is T-shaped. The support frame 3 is slidably connected to the instrument 1 through the slide groove 31. Through the connection between the support frame 3 and the slide groove 31, the position of the support frame 3 on the instrument 1 is changed under the action of the slide groove 31. Through the action of the support frame 3, the connection angle of the connecting wire 11 on the instrument 1 can be limited and supported, avoiding excessive bending of the connecting wire 11, which could cause the connecting wire 11 to break and affect its connection performance and lifespan.

[0033] Furthermore, the abutment block 32 is elastically slidably connected to the support spring 34 and the connecting groove 33. The abutment block 32 abuts against the surface of the instrument 1 through the abutment frame 3. A rubber pad is provided on the surface of the abutment block 32 in contact with the instrument 1. With the connection between the abutment frame 3 and the connecting groove 33, and the connection between the abutment block 32 and the support spring 34, the abutment block 32 achieves an elastic sliding effect in the connecting groove 33. Through the abutment block 32 abutting against the instrument 1, the abutment frame 3 achieves a supporting effect at the position of action on the instrument 1.

[0034] Working principle: During the binding operation after the connecting wire 11 is stored, the screw 26 is rotated through the connection of the placement platform 2 and the placement plate 23, causing the abutment 27 and the binding strap 24 to separate. At this time, the binding strap 24 slides in the connecting frame 25, causing the binding strap 24 and the connecting frame 25 to separate. The connecting wire 11 is connected to the placement plate 23. Then, the binding strap 24 binds the connecting wire 11 and passes through the connecting frame 25. The screw 26 is rotated in the opposite direction, causing the abutment 27 and the binding strap 24 to abut, achieving the binding and support effect of the connecting wire 11. The water level sensor 12 is stored on the surface of the placement platform 2 through the support plate 21 and the abutment plate 22. Under the sliding connection of the abutment 3 and the slide groove 31, the abutment block 32 and the support spring 34 are connected, causing the abutment block 32 to abut against the instrument 1, completing the abutment support operation of the abutment 3 at the position of action on the instrument 1, improving the abutment positioning performance of the connecting wire 11, avoiding excessive bending of the connecting wire 11, and thus improving the service life and performance of the connecting wire 11.
