Description

Technical Field

[0002] Geological exploration is the abbreviation of geological exploration work, which is a survey and study with different focuses on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area. At present, the observation of groundwater level is mainly carried out by opening vertical observation wells at selected observation points and observing through steel ruler water level gauges. When in use, the end of the steel ruler water level gauge is lowered along the observation well. When the sensor at the end drops to the groundwater level, an alarm is issued.

[0003] However, the traditional steel ruler water level gauge is not equipped with a protective mechanism. When the steel ruler water level gauge is in use, the water level probe needs to be placed into the logging well using a steel ruler cable. However, in the process of retracting and releasing the rope, the water level probe is very likely to be scratched against the inner wall of the detection well, which will greatly reduce the service life of the water level probe and even cause damage to the water level probe, increasing property losses.

[0004] Therefore, a groundwater level observation device for hydrogeological exploration is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figures 1 to 4 As shown, this embodiment provides a groundwater level observation device for hydrogeological exploration, comprising:

[0028] A carrying plate 1, on which two mounting seats 2 are symmetrically fixed, a rotating shaft 3 is rotatably installed between the two mounting seats 2, one end of the rotating shaft 3 extends out of the mounting seat 2 and is transmission-connected to a power mechanism 4, a winding drum 5 is fixedly connected to the outside of the rotating shaft 3, and a cable 6 is wound on the winding drum 5;

[0029] The limiting assembly comprises an upper limiting ring 7, a middle limiting ring 8 and a lower limiting ring 9 which are connected to each other. The upper limiting ring 7, the middle limiting ring 8 and the lower limiting ring 9 are coaxially arranged, and the cable 6 passes through the centers of the upper limiting ring 7, the middle limiting ring 8 and the lower limiting ring 9 in sequence;

[0030] The water level measuring head 10 is detachably connected to the tail end of the cable 6 .

[0031] When in use, move the carrying plate 1 to the side of the well logging, pass the tail end of the cable 6 through the upper limit ring 7, the middle limit ring 8 and the lower limit ring 9 in sequence, and then connect the water level probe 10 to the tail end of the cable 6; fix the limit assembly at the well logging wellhead position, at this time, the axes of the upper limit ring 7, the middle limit ring 8 and the lower limit ring 9 are located on the central axis of the well logging, and the cable 6 restricted by the upper limit ring 7, the middle limit ring 8 and the lower limit ring 9 is also restricted on the central axis of the well logging; start the power mechanism 4 to lower the cable 6. Since the cable 6 is restricted, it is not easy to shake during the lowering process, and the water level probe 10 is not easy to touch the inner wall of the well logging, which can effectively Prevent the water level probe 10 at the tail end of the cable 6 from being damaged; after the water level probe 10 reaches the water surface and measures the water level, start the power mechanism 4 to rotate the rotating shaft 3 in the opposite direction, so that the winding drum 5 drives the cable 6 to be wound on the winding drum 5, and the cable 6 is recovered. Similarly, during the recovery process, since the cable 6 is limited, the cable 6 is not easy to shake, and the water level probe 10 is not easy to touch the inner wall of the logging well, which can effectively prevent the water level probe 10 from being damaged. When the water level probe 10 is close to the lower limit ring 9, the limit assembly is disassembled and cleaned from the wellhead and moved upward, and then the water level probe 10 is disassembled, the cable 6 is pulled out of the limit assembly and wound around the winding drum 5, and the measurement is completed. In the utility model, the cable 6 is limited at the upper, middle and lower positions by the upper limit ring 7, the middle limit ring 8 and the lower limit ring 9 at the wellhead of the well logging, so that the cable 6 moves as a whole along the center of the well logging when being lowered or recovered, and the rotation of the winding drum 5 or external impact is not likely to affect the angle below the cable 6, the cable 6 is not likely to shake in the well, and the water level probe 10 is not likely to touch the inner wall of the well logging, which can effectively prevent the water level probe 10 at the tail end of the cable 6 from being damaged.

[0032] Furthermore, the power mechanism 4 can be a rotating handle that is rotated manually, or a motor driven by electricity, or any other mechanism that can rotate the rotating shaft 3.

[0033] A further optimization scheme is that the limit assembly also includes a plurality of sleeves 11 circumferentially fixed to the middle limit ring 8, a telescopic rod 12 is slidably connected in the sleeve 11, a fixed block 13 is fixed to the outer end of the telescopic rod 12, an upper connecting rod 14 is hinged at the upper end of the fixed block 13, and a plurality of upper connecting rods 14 are circumferentially hinged to the outside of the upper limit ring 7; a lower connecting rod 15 is hinged at the lower end of the fixed block 13, and a plurality of lower connecting rods 15 are circumferentially hinged to the outside of the lower limit ring 9; a spring 16 is fixed between the upper limit ring 7 and the middle limit ring 8, and the cable 6 passes through the center of the spring 16.

[0034] When the spring 16 is in a normal state, the upper limit ring 7 and the lower limit ring 9 move closer to the middle limit ring 8, and the upper connecting rod 14 and the lower connecting rod 15 are hinged to the fixed block 13 and extend outward, pulling the telescopic rod 12 to extend, so that the fixed block 13 is away from the middle limit ring 8; when the limit assembly needs to be fixed to the wellhead, it is necessary to manually pull the distance between the upper limit ring 7 and the middle limit ring 8, and hold all the upper connecting rods 14 with both hands to fix them. At this time, the spring 16 is stretched and elastic potential energy is accumulated, and the upper limit ring 7 and the lower limit ring 9 are away from the middle limit ring 8, and the upper connecting rod 14 and the lower connecting rod 15 are hinged to the fixed block 13. The middle limit ring 8 approaches, pulling the telescopic rod 12 to retract into the sleeve 11, thereby making the fixed block 13 close to the middle limit ring 8, and the overall diameter of the limit assembly is shortened; then the limit assembly is placed in the wellhead, and then the upper connecting rod 14 is slowly released, the elastic potential energy of the spring 16 is gradually released, the upper limit ring 7, the middle limit ring 8, and the lower limit ring 9 gradually approach each other, and the upper connecting rod 14 and the lower connecting rod 15 are hinged to the fixed block 13. The end extends outward, pulling the telescopic rod 12 to extend, so that the fixed block 13 is away from the middle limit ring 8 and abuts against the inner wall of the wellhead, and several fixed blocks 13 work together to fix the limit assembly in the wellhead.

[0035] According to a further optimized solution, the fixing block 13 is an arc-shaped block, and a cushion block 17 is fixedly connected to the outer side of the fixing block 13 .

[0036] The fixed block 13 is arc-shaped and fits the inner wall of the wellhead better. The cushion block 17 has a certain elasticity and can better adapt to the uneven inner wall of the wellhead. Both are for increasing the contact area between the fixed block 13 and the inner wall of the wellhead, increasing the friction force, and making the limit assembly more firmly fixed.

[0037] As a further optimized solution, two extension rods 18 are fixedly connected to one side of the support plate 1 corresponding to the winding drum 5 , and a guide wheel 19 is rotatably connected between the two extension rods 18 . The guide wheel 19 extends out of the support plate 1 , and the cable 6 is wound on the guide wheel 19 .

[0038] If there is no guide wheel 19, and the cable 6 is directly extended into the logging from one side of the bearing plate 1, the cable 6 will rub against the edge of the bearing plate 1, which may easily cause the cable 6 to break. The guide wheel 19 can convert the sliding friction between the cable 6 and the edge of the bearing plate 1 into rolling friction, reducing the wear of the cable 6.

[0039] According to a further optimized solution, a U-shaped groove 20 is provided at the center of the surface of the guide wheel 19 , and the cable 6 is embedded in the U-shaped groove 20 .

[0040] The U-shaped groove 20 is provided so that the cable 6 is embedded in the U-shaped groove 20 , thereby preventing the cable 6 from slipping off the guide wheel 19 .

[0041] According to a further optimized solution, a plurality of universal wheels 21 are fixedly connected to the bottom surface of the carrying plate 1 , and a push handle 22 is fixedly connected to one side of the carrying plate 1 .

[0042] The provision of the universal wheel 21 and the push handle 22 facilitates the movement of the carrying plate 1 .

[0043] According to a further optimized solution, the water level probe 10 is wrapped with anti-collision cotton 23, a hanging ring is fixedly connected to the top of the water level probe 10, a hook is fixedly connected to the tail end of the cable 6, and the hanging ring is hung on the hook.

[0044] The anti-collision cotton 23 wraps the water level probe 10 to further enhance the anti-collision protection of the water level probe 10; the design of the hanging ring and the hook facilitates the detachable connection between the water level probe 10 and the tail end of the cable 6.

[0045] According to a further optimized solution, a wire retaining drum 24 is fixedly connected to both sides of the winding drum 5 .

[0046] The cable retaining plate 24 prevents the cable 6 from being stuck between the mounting seat 2 and the winding drum 5, thereby affecting the retraction and release of the cable 6.

[0047] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0048] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
