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

[0002] Geotechnical engineering investigation is a crucial foundational step in engineering construction. It aims to investigate, analyze, and evaluate the properties, geological structure, and hydrogeological conditions of the soil and rock mass at the engineering site, providing reliable geological data for engineering design, construction, and operation. Among these, borehole water level measurement is a key step in obtaining hydrogeological data of the site. It is mainly used to determine the type of groundwater (such as unconfined water and confined water), water level depth, dynamic changes in water level, and aquifer permeability. It has important guiding significance for foundation design, pit dewatering, and seepage prevention treatment. Generally, corresponding measuring devices are used for measurement operations.

[0003] In the field of geotechnical engineering investigation, existing measuring devices generally use multiple components such as water level measuring ropes, electrical water level gauges and pressure water level gauges to carry out measurement operations. However, in actual use, they are usually supported by support frames or frames to provide stability, which results in the large size of the entire equipment, making it inconvenient for staff to handle and transport.

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the aforementioned or existing technologies, the current methods of providing stability typically involve support frames or racks, resulting in a large overall size of the equipment, which is inconvenient for workers to handle and transport.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A borehole water level measuring device for geotechnical engineering investigation, characterized in that it comprises:

[0008] A support rod, with a tray fixedly installed at the top end of the support rod and a fixing cylinder fixedly installed at the bottom end of the support rod, and a support mechanism provided on the outside of the support rod;

[0009] The support mechanism includes a storage groove, which is formed on the outer wall of the support rod. An abutment plate extends through the inside of the storage groove. Rotating shafts are fixedly installed on both sides of the outer wall of the abutment plate at one end of the storage groove. A locking groove is formed inside the storage groove at the position corresponding to the rotating shaft. A soil-breaking cone is fixedly installed on the outer wall of the abutment plate. An abutment ring is slidably connected to the outer wall of the support rod.

[0010] As a further improvement of this utility model: the abutment ring is threadedly connected to the bearing rod, and the abutment ring is tightly fitted to the abutment plate.

[0011] As a further improvement of this utility model: a rubber pad is embedded at the bottom end of the fixed cylinder, and a protective mechanism is provided inside the rubber pad.

[0012] As a further embodiment of this utility model: the protective mechanism includes a measuring device body, the measuring device body extending through the bottom end of the rubber pad, and a measuring head extending through the bottom end of the measuring device body.

[0013] As a further improvement of this utility model: a connecting ring is fixedly installed on one side of the measuring head at the bottom of the main body of the measuring device, and a protective shell is fitted over the connecting ring.

[0014] As a further improvement of this utility model: a filter screen is embedded in the outer wall of the protective shell, and a measuring rope is provided at the bottom of the main body of the measuring device.

[0015] As a further improvement of this utility model: a mounting shell is fixedly installed on the top of the tray, and a servo motor is embedded on one side of the outer wall of the mounting shell.

[0016] As a further improvement of this utility model: the power output end of the servo motor is fixedly mounted with a drive shaft, and a limit plate is fixedly mounted on the outer wall of the drive shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the design of a storage groove, abutment plate, rotating shaft, locking groove and abutment ring, enables the device to be quickly unfolded or retracted by rotating the abutment plate. When retracted, it forms a rod-shaped object, which is convenient for staff to carry or transport. When unfolded, the abutment plate is slid and the position of the abutment ring is adjusted, which can quickly unfold the device and improve the stability after unfolding by using four sets of abutment plates.

[0019] 2. This utility model, through the design of rubber pads, connecting rings, protective shells, and filter screens, can protect the main body of the measuring equipment during transportation and provide protection when the measuring head moves up and down in the hole, avoiding damage from bumps.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1 to 3This is the first embodiment of the present utility model. This embodiment provides a borehole water level measuring device for geotechnical engineering investigation, including: a bearing rod 1, a tray 2 fixedly installed at the top end of the bearing rod 1, a fixing cylinder 3 fixedly installed at the bottom end of the bearing rod 1, and a support mechanism 4 provided on the outside of the bearing rod 1.

[0031] The support mechanism 4 includes a storage groove 401, which is formed on the outer wall of the support rod 1. An abutment plate 402 extends through the inside of the storage groove 401. Rotating shafts 403 are fixedly installed on both sides of the outer wall of one end of the abutment plate 402. A locking groove 404 is formed inside the storage groove 401 corresponding to the position of the rotating shaft 403. A ground-breaking cone 406 is fixedly installed on the outer wall of the abutment plate 402. An abutment ring 405 is slidably connected to the outer wall of the support rod 1.

[0032] Specifically, the abutment ring 405 is threadedly connected to the bearing rod 1, and the abutment ring 405 is tightly fitted to the abutment plate 402.

[0033] Furthermore, by connecting the abutment ring 405 to the bearing rod 1 by thread, the abutment plate 402 can be limited to prevent loosening after the device is unfolded, and the abutment plate 402 can be covered and closed to prevent rotation when the device is not unfolded.

[0034] In use, the contact plate 402, through the cooperation of the rotating shaft 403 and the engaging groove 404, rotates and engages with the bearing rod 1, and can be located inside the storage groove 401. It is limited by the contact ring 405, so that the device can be retracted for easy carrying. When unfolded, the position of the contact ring 405 is adjusted to allow the contact plate 402 to rotate and slide along the engaging groove 404 and the storage groove 401, thereby conforming to the ground and cooperating with the ground-breaking cone 406 to provide stability by hammering into the ground. Adjusting the contact ring 405 to press the contact plate 402 can improve stability. The device can be adjusted according to the situation.

[0035] In summary, by inserting the contact plate 402 into the storage slot 401 and with the contact ring 405 in place, a rod-shaped object can be formed, which facilitates the carrying and transportation of the device. When measuring, the contact plate 402 rotates and is pressed by the contact ring 405, allowing it to unfold and fit against the ground or base layer, thereby stabilizing the device and enabling measurement operations. It can be adjusted according to the situation, improving the flexibility and convenience of the entire equipment.

[0036] Example 2

[0037] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for a borehole water level measuring device for geotechnical engineering investigation.

[0038] Specifically, a rubber pad 5 is embedded at the bottom of the fixed cylinder 3, and a protective mechanism 6 is provided inside the rubber pad 5.

[0039] Furthermore, the rubber pad 5 provides a certain degree of protection, safeguarding the device.

[0040] Specifically, the protective mechanism 6 includes a measuring device body 601, which extends out of the bottom of the rubber pad 5, and a measuring head 602 extends out of the bottom of the measuring device body 601.

[0041] Furthermore, when the device is not unfolded, the rubber pad 5 protects the main body 601 of the measuring device from external impacts. When unfolding for measurement, the main body 601 of the measuring device needs to be pulled out of the rubber pad 5 to prevent the elastic compression from preventing the main body 601 of the measuring device from being raised or lowered.

[0042] Specifically, a connecting ring 603 is fixedly installed on one side of the measuring head 602 at the bottom of the measuring device body 601, and a protective shell 604 is fitted over the connecting ring 603.

[0043] Furthermore, the connecting ring 603 is threadedly connected to the protective shell 604, thereby covering the outer wall of the measuring head 602 and preventing the measuring head 602 from being damaged by bumps during the lifting and lowering process.

[0044] Specifically, a filter screen 605 is embedded in the outer wall of the protective shell 604, and a measuring rope 606 is provided at the bottom of the main body of the measuring device 601.

[0045] Furthermore, the filter 605 embedded in the protective shell 604 facilitates the sensing of external conditions by the measuring head 602, while also providing a protective effect.

[0046] Specifically, a mounting shell 7 is fixedly installed on the top of the tray 2, and a servo motor 8 is embedded on one side of the outer wall of the mounting shell 7.

[0047] Furthermore, the mounting shell 7 is fixed by the tray 2, which facilitates the fixing and support of the servo motor 8.

[0048] Specifically, a drive shaft 9 is fixedly installed at the power output end of the servo motor 8, and a limit plate 10 is fixedly installed on the outer wall of the drive shaft 9.

[0049] Furthermore, the servo motor 8 is controlled by an external remote control device via a signal, which in turn drives the measuring rope 606 via the drive shaft 9, thereby controlling the lifting and lowering of the measuring head 602. The mounting shell 7 is equipped with a glass plate to facilitate observation of the winding and unwinding of the measuring rope 606.

[0050] In use, the measuring device body 601 wrapped by the rubber pad 5 is manually pulled out, and under the support of the mounting shell 7, the measuring rope 606 is wound up by the servo motor 8 and drive shaft 9, thereby controlling the measuring device body 601 and adjusting the lifting and lowering of the measuring head 602 to perform the measurement operation. It is connected to the protective shell 604 by the connecting ring 603, which is convenient for disassembly and assembly and can protect the measuring head 602. The filter screen 605 embedded in the protective shell 604 provides protection without affecting the measurement effect. The measuring rope 606 is limited by the limit plate 10 to prevent it from getting tangled with the power end of the servo motor 8 during the winding process.

[0051] In summary, the main body 601 of the measuring device is integrated with components such as the outer shell and various water level gauges. The sensing ends of each water level gauge are located inside the measuring head 602. This is existing technology and will not be described in detail here. The rubber pad 5 can protect the main body 601 of the measuring device during transportation. At the same time, the detachable protective shell 604 and the filter screen 605 can protect the measuring head 602 during the lifting process, avoiding collisions with the harder parts inside the hole and preventing damage, and avoiding affecting the measurement effect of the measuring head 602.
