Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and more specifically, to a groundwater level detection device for ecological restoration. Background Technology

[0002] Ecological restoration aims to restore polluted or damaged environments. Its core is to combine human intervention with natural recovery to allow ecosystems to gradually recover or move towards a virtuous cycle. This process not only focuses on restoring ecological functions but also emphasizes the stability and sustainability of the ecosystem. Groundwater level is the most direct reflection of the state of the groundwater system, and its changes can intuitively reflect the impact of ecological restoration measures on groundwater recharge, runoff, and discharge processes. Therefore, groundwater level monitoring plays a crucial role in ecological restoration. It is not only a fundamental indicator for assessing restoration effectiveness but also a key link in guiding restoration strategy formulation, ensuring ecological security, and promoting the sustainable recovery of ecosystems.

[0003] When conducting groundwater level testing, the water level detection probe needs to be placed into the testing well. During the lowering process, if there are obstructions such as aquatic plants on the well wall, the water level detection probe is easily obstructed or collides with the well wall. Therefore, most current testing devices are equipped with protective cylinders to protect the water level detection probe. However, when the protective cylinder comes into contact with groundwater, there is air inside, and the water will enter the water level detection probe with a delay. This causes the position of the water level detection probe when it comes into contact with the water to deviate from the actual water level, thus affecting the test results. Summary of the Invention

[0004] The purpose of this invention is to provide a groundwater level detection device for ecological restoration, which can protect the water level detection probe while avoiding deviations in the height at which the probe contacts the water, thus preventing the detection results from being affected.

[0005] This invention is achieved through the following technical solution: a groundwater level detection device for ecological restoration, comprising: a support frame fixed at the wellhead of a detection well; a wire laying mechanism including a support base, a wire laying reel, a wire laying motor, and a wire laying rope, wherein the support base is mounted on the support frame, the wire laying reel is rotatably mounted on the support base, the wire laying motor is fixedly mounted on the support base and can drive the wire laying reel to rotate, and the wire laying rope is wound around the wire laying reel; a water level detection probe fixedly mounted at the end of the wire laying rope away from the wire laying reel; and a protective mechanism including a protective base and a protective cover, wherein the protective base is detachably mounted on the wire laying rope, and the protective cover includes a plurality of protective plates circumferentially distributed at the bottom of the protective base, the protective plates being rotatably connected to the bottom of the protective base;

[0006] The protective sheet is a floating sheet that can float on the water surface. When the protective sheet is in a vertical state, the height of the lowest point of the protective sheet is lower than the height of the bottom of the water level detection probe. When the protective sheet is rotated to an inclined state by buoyancy, the height of the lowest point of the protective sheet is higher than the height of the bottom of the water level detection probe.

[0007] Furthermore, there is a gap between two adjacent protective plates and an accordion-style baffle is connected to them.

[0008] Furthermore, the bottom of the protective sheet is provided with an arc-shaped portion, which extends in a direction away from the axis of the protective seat.

[0009] Furthermore, a connecting block is provided on the side of each of the two adjacent arc-shaped portions that are close to each other, and a communicating groove is opened at the bottom of the two adjacent connecting blocks, and the groove is filled with water-soluble adhesive.

[0010] Furthermore, the water-soluble adhesive is polyvinyl alcohol adhesive.

[0011] Furthermore, a conical ring is provided at the bottom of the protective base and outside the protective cover to limit the rotation angle of the protective plate.

[0012] Furthermore, the protective seat includes an inner seat body and an outer seat body, the inner seat body is provided with an external thread, and the outer seat body is provided with a threaded hole that matches the external thread.

[0013] Furthermore, a limiting component is provided on the unwinding rope and above the water level detection probe. The limiting component includes a limiting block and a tightening bolt. The inner seat abuts against the limiting block and has a gap with the water level detection probe.

[0014] Furthermore, the bracket includes an outer ring, an inner disc, and multiple connecting rods. The support base is detachably mounted on the inner disc via connecting bolts. A through hole is provided at the center of the inner disc for the unwinding of the rope and the passage of the protective mechanism.

[0015] Furthermore, the support base is provided with a guide wheel for defining the position of the unwinding rope, and the unwinding rope is laid on the guide wheel and passes through the center of the through hole.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0017] 1. This invention protects the water level detection probe by setting up a protective mechanism. When the protective plate is in a vertical state before entering the groundwater, the height of the lowest end of the protective plate is lower than the height of the bottom of the water level detection probe, so as to provide better protection for the water level detection probe. After the protective plate enters the groundwater, it is rotated to an inclined state by buoyancy, and the height of the lowest end of the protective plate is higher than the height of the bottom of the water level detection probe. Multiple protective plates are spread out in all directions so that the bottom end of the water level detection probe can immediately contact the water when it reaches the groundwater surface, thereby improving the accuracy of the water level detection results.

[0018] 2. The present invention creates a groove in the connecting block at the bottom of the protective sheet and fills the groove with water-soluble adhesive. When the protective mechanism is placed into the detection well, the water-soluble adhesive connects two adjacent connecting blocks. When the bottom of the connecting block comes into contact with groundwater, the water-soluble adhesive can quickly dissolve, releasing the restriction on the position between the two connecting blocks, allowing the protective sheet to rotate under the action of buoyancy.

The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] Example

[0029] The following is for reference Figures 1-6 As shown in the figure, and further explained with reference to specific embodiments, this embodiment provides a groundwater level detection device for ecological restoration, including a support 1, a wire laying mechanism 2, a water level detection probe 3, and a protective mechanism 4. The support 1 is fixed at the wellhead of the detection well. The wire laying mechanism 2 includes a support base 21, a wire laying reel 22, a wire laying motor 23, and a wire laying rope 24. The support base 21 is fixedly mounted on the support 1. The wire laying reel 22 is rotatably mounted on the support base 21. The wire laying motor 23 is fixedly mounted on the support base 21 and can drive the wire laying reel 22 to rotate. The wire laying rope 24 is wound around the wire laying reel 22. The water level detection probe 3 is located at the end of the wire laying rope 24 away from the wire laying reel 22. The protective mechanism 4 includes a protective base 41 and a protective cover 42. The protective base 41 is detachably mounted on the unwinding rope 24. The protective cover 42 includes multiple protective plates 421 circumferentially distributed at the bottom of the protective base 41. The protective plates 421 are rotatably connected to the bottom of the protective base 41. In this embodiment, the protective plates 421 are connected to the protective base 41 by flexible rubber sheets to achieve a rotatable connection. In other embodiments, other rotatable connection structures such as hinges or shafts can also be used. The unwinding motor 23 drives the unwinding reel 22 to rotate, thereby unwinding the unwinding rope 24 and lowering the water level detection probe 3 into the monitoring well. During the lowering process, when the water level detection probe 3 is blocked by the well wall or other obstacles, the protective cover 42 can act as a barrier outside the water level detection probe 3, thereby preventing damage to the water level detection probe 3. When the protective mechanism 4 enters the groundwater layer, multiple protective plates 421 can rotate simultaneously and spread out in a widening shape, thereby preventing the groundwater from being delayed in contacting the water level gauge probe due to the effect of the internal air of the protective cover 42, thus improving the accuracy of the detection results.

[0030] Reference Figure 1 , Figure 2As shown, the bracket 1 includes an outer ring 11, an inner disc 12, and multiple connecting rods 13. The support base 21 is detachably mounted on the inner disc 12 by connecting bolts 211. A through hole 121 is provided at the center of the inner disc 12 for the unwinding rope 24 and the protective mechanism 4 to pass through. The support base 21 is provided with a guide wheel 212 for limiting the position of the unwinding rope 24. When the unwinding rope 24 is placed on the guide wheel 212, it passes through the center of the through hole 121 so that the water level detection probe 3 and the protective mechanism 4 are in the center of the detection well, thereby minimizing the possibility of the overall structure formed by the water level detection probe 3 and the protective mechanism 4 colliding with the well wall of the detection well.

[0031] Reference Figure 3 , Figure 4 As shown, the protective sheet 421 is a floating sheet capable of floating on the water surface. The density of the protective sheet 421 is less than that of water. Therefore, before entering groundwater, the protective sheet 421 is in a vertical state under its own weight, and after entering the groundwater, it can flip over under the buoyancy of the water. The bottom of the protective sheet 421 has an arc-shaped portion 423 that extends away from the axis of the protective base 41, ensuring that the protective sheet 421 has a tendency to flip outwards when entering groundwater, thus making the protective cover 42 formed by multiple protective sheets 421 flared. When the protective plate 421 is in a vertical position, the height of the lowest end of the protective plate 421 is lower than the height of the bottom of the water level detection probe 3. The protective cover 42 can provide good protection for the water level detection probe 3. When the protective mechanism 4 and the overall structure of the water level detection probe 3 collide with the well wall at any angle, the water level detection probe 3 will not directly contact the well wall and be damaged. When the protective plate 421 is rotated to an inclined state by buoyancy, the height of the lowest end of the protective plate 421 is higher than the height of the bottom of the water level detection probe 3. Multiple protective plates 421 spread out in all directions so that the bottom end of the water level detection probe 3 can immediately contact the water when it reaches the surface of the groundwater, thereby improving the accuracy of the water level detection results.

[0032] Reference Figure 4As shown, there is a gap between two adjacent protective plates 421 to ensure that the flipping of multiple protective plates 421 will not obstruct each other and to ensure the smoothness of the flipping process. An accordion-style baffle 422 is also connected between two adjacent protective plates 421 to ensure that mud and water adhering to the well wall will not enter the water level detection probe 3 through the gap during the movement inside the detection well. A conical ring 413 is provided at the bottom of the protective base 41 and outside the protective cover 42 to limit the rotation angle of the protective plate 421. When the protective plate 421 rotates to the point where the height of its bottom end is higher than the height of the bottom of the water level detection probe 3, it does not need to continue rotating. At this time, the accordion-style baffle 422 also switches from the folded state to the unfolded state. The conical ring 413 provides a certain degree of protection for the accordion-style baffle 422 by limiting the rotation angle of the protective plate 421, and prevents the accordion-style baffle 422 from being over-unfolded and damaged.

[0033] Reference Figure 4 , Figure 5 As shown, each of the two adjacent arc-shaped portions 423 has a connecting block 424 on its side closest to each other. The bottom of each adjacent connecting block 424 has a communicating groove filled with water-soluble adhesive 425. When the protective mechanism 4 is placed into the detection well, the adjacent connecting blocks 424 are connected by the water-soluble adhesive 425. When the bottom of the connecting block 424 comes into contact with groundwater, the water-soluble adhesive 425 dissolves rapidly, releasing the restriction on the position between the two connecting blocks 424, allowing the protective plate 421 to rotate under buoyancy. In this embodiment, the water-soluble adhesive 425 is polyvinyl alcohol adhesive. In other embodiments, a water-soluble hot melt adhesive can also be used, as long as it dissolves quickly in water to release the positioning effect between the two connecting blocks 424.

[0034] Reference Figure 4 As shown, the protective seat 41 includes an inner seat body 411 and an outer seat body 412. The inner seat body 411 has external threads, and the outer seat body 412 has threaded holes that match the external threads. The protective cover 42 is installed on the outer seat body 412. The outer seat body 412 can be removed from the inner seat body 411 for separate inspection or maintenance through a threaded connection, thus improving convenience. A limiting member 25 is provided on the unwinding rope 24 and above the water level detection probe 3. The limiting member 25 includes a limiting block 251 and a clamping bolt 252. The inner seat body 411 abuts against the limiting block 251 and has a gap between it and the water level detection probe 3. The limiting member 25 supports the inner seat body 411 to prevent the inner seat body 411 from transmitting pressure to the water level detection probe 3, which could cause the connection between the water level detection probe 3 and the unwinding rope 24 to loosen or even break.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
