Description

Technical Field

[0001] This invention relates to the field of permeability testing technology, and in particular to a groundwater permeability testing device. Background Technology

[0002] Groundwater permeability testing is an important part of environmental monitoring and hydrogeological research. It is mainly used to assess groundwater flow characteristics, water quality changes, and soil permeability. Traditional groundwater permeability testing devices usually adopt a fixed design, which involves inserting the testing unit into the groundwater and using the principle of permeability to sample and analyze the groundwater.

[0003] However, existing detection devices can only detect in a single direction in practical applications and cannot simultaneously acquire data from both the upstream and downstream sides, which limits the comprehensiveness of the detection. Furthermore, the device orientation needs to be adjusted frequently, and in dark environments, it is impossible to adjust the orientation precisely, leading to inaccurate detection data.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] 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 throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0032] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a groundwater permeability detection device, including a detection unit 1, including a connecting rod 11, a sealing cover 12 rotatably disposed at the bottom end of the connecting rod 11, and a reaction box 13 disposed at the bottom of the sealing cover 12.

[0033] Steering unit 2 includes a connecting cover 21 disposed on the inner wall of the sealing cover 12, an extrusion assembly 22 disposed in the inner cavity of the sealing cover 12, a locking assembly 23 disposed on one side of the extrusion assembly 22, an inflation assembly 24 disposed in the sealing cover 12, an air outlet pipe 25 disposed at the air outlet end of the inflation assembly 24, an insertion rod 26 disposed at one end of the air outlet pipe 25, and an airbag 27 disposed on the outer wall of the insertion rod 26.

[0034] The reaction box 13 includes a box body 131 threaded to the bottom of the sealing cover 12, a partition 132 disposed in the inner cavity of the box body 131, and permeation grooves 133 disposed on both sides of the partition 132.

[0035] Insert rod 26 is located between extrusion assembly 22 and connecting cover 21.

[0036] It should be noted that a sealing cover 12 is rotatably connected to the bottom of the connecting rod 11, and a reaction box 13 is threadedly connected to the bottom of the sealing cover 12;

[0037] A partition 132 is fixedly connected to the inner cavity of the reaction box 13. The partition 132 divides the inner cavity of the reaction box 13 into two cavities, and two permeation grooves 133 are symmetrically opened on the outer wall of the box 131.

[0038] A connecting cap 21 is inserted into the inner wall of the sealing cap 12. The connecting cap 21 is located directly above one of the permeation grooves 133. When the airbag 27 is squeezed out from the sealing cap 12 and inflates, it will pull the sealing cap 12 to rotate, which will drive the two permeation grooves 133 at the bottom, one facing away from the water and the other facing the water. An extrusion assembly 22 is provided in the inner cavity of the sealing cap 12. The extrusion assembly 22 can squeeze the insertion rod 26 and drive the airbag 27 to be squeezed out of the sealing cap 12. In the normal state, the extrusion assembly 22 is locked by the locking assembly 23. The locking assembly 23 is also installed in the inner cavity of the sealing cap 12 and is a remote control component. An inflation assembly 24 is also installed on the sealing cap 12. The inflation assembly 24 can push compressed gas into the airbag 27 through the air outlet pipe 25. One end of the air outlet pipe 25 is connected to one end of the insertion rod 26.

[0039] In use, the detection material is placed in the two cavities of the reaction box 13, and then the connecting rod 11 is inserted into the underground river in the detection area. The locking component 23 is opened, and the extrusion component 22 squeezes the insertion rod 26. First, the connecting cover 21 is pushed out of the sealing cover 12. Then, the extrusion component 22 continues to push the insertion rod 26, causing the airbag 27 to protrude from the sealing cover 12. Under the action of the extrusion component 22, about 8 / 9 of the airbag 27 is exposed. The airbag 27 is inflated by the inflation component 24. The airbag 27 expands and is connected to the sealing cover 12 by the air outlet pipe 25. Under the action of water flow, the air vent 25 pulls the sealing cover 12 to rotate, so that the two infiltration tanks 133 form a water-facing state and a water-repellent state. After the preset detection time is reached, the device is pulled out by the connecting rod 11. During the pulling process, the air bladder 27 will be located below the reaction box 13 due to its own weight and the weight of the water flow. Therefore, the hole opened during the pulling process does not affect the removal of the detection unit 1. After the reaction box 13 is removed, it is unscrewed from the sealing cover 12 to realize the simultaneous detection of the groundwater in both the water-facing and water-repellent states.

[0040] In summary, by setting up an airbag, the reaction box 13 is rotated according to the direction of the underground river, so that the two detection chambers of the reaction box 13 always face the water on one side and face away from the water on the other side, so that the water-facing and water-repellent sides of the groundwater can be detected at the same time. In addition, under normal conditions, the airbag 27 is stored in the sealing cover 12, which can prevent the airbag 27 from being scratched by the rocks in the cave.

[0041] like Figures 3 to 6 As shown, in one optional embodiment, the extrusion assembly 22 includes a positioning rod 221 disposed on the inner wall of the sealing cover 12, a connecting frame 222 slidably disposed on the outer wall of the positioning rod 221, and a tension spring 223 disposed between the connecting frame 222 and the inner cavity of the sealing cover 12.

[0042] It should be noted that a positioning rod 221 is horizontally fixedly connected to the inner wall of the sealing cover 12, and there are two sets of positioning rods 221. A connecting frame 222 is slidably connected to the outer wall of the positioning rod 221, and a tension spring 223 is provided between the connecting frame 222 and the sealing cover 12.

[0043] When in use, when the locking component 23 is opened, the tension spring 223 loses its restraint and contracts, which pulls the connecting bracket 222 to slide outward, thereby pushing the insert rod 26 to open the connecting cover 21 and bringing the airbag 27 out of the sealing cover 12.

[0044] like Figures 3 to 6 As shown, as an optional embodiment: the locking component 23 includes a latch component 231 disposed on both sides of the connecting frame 222, and a thumb switch 232 disposed above the control end of the latch component 231;

[0045] The locking assembly 231 includes a column 2311 disposed in the inner cavity of the sealing cover 12, a push plate 2312 slidably disposed on the outer wall of the column 2311, a buckle plate 2313 rotatably disposed on the outer wall of the push plate 2312, a first spring 2314 disposed between the buckle plate 2313 and the push plate 2312, a second spring 2315 disposed between the lower surface of the push plate 2312 and the bottom end of the column 2311, and a limiting rod 2316 and a guide rod 2317 disposed on both sides of the buckle plate 2313.

[0046] It should be noted that the upright 2311 is fixedly installed on the inner wall of the sealing cover 12 and located on both sides of the connecting frame 222. A push plate 2312 is slidably connected to the upright 2311, and a buckle plate 2313 is rotatably connected to the top of the push plate 2312. A limit rod 2316 is fixedly connected to one side of the buckle plate 2313 and on the upper surface of the push plate 2312. The limit rod 2316 limits the rotation angle of the buckle plate 2313, thereby locking the buckle plate 2313 to the connecting frame 222. A first spring 2314 is provided between the buckle plate 2313 and the push plate 2312. 314 pushes the buckle plate 2313 to rotate, so that it fits tightly against the limit rod 2316. A guide rod 2317 is also fixedly connected to one side of the buckle plate 2313. The guide rod 2317 and the push plate 2312 are slidably connected. A second spring 2314 is provided between the bottom of the push plate 2312 and the bottom of the column 2311. The second spring 2314 presses upward. The thumb switch 232 is located above the push plate 2312. When the thumb switch 232 is activated, it will push the push plate 2312 downward. The push plate 2312 drives the buckle plate 2313 to move down and be offset from the connecting frame 222.

[0047] In use, by activating the thumb switch 232, the thumb switch 232 pushes the push plate 2312 downward, the push plate 2312 drives the buckle plate 2313 to move downward and be misaligned with the connecting frame 222. The connecting frame 222 is no longer restricted by the buckle plate 2313 and moves under the action of the extrusion component 22 to complete the release of the airbag 27.

[0048] When the airbag 27 needs to be retracted into the sealing cover 12, the thumb switch 232 retracts. Under the action of the second spring 2314, the push plate 2312 slides upward to reset and pushes the insert rod 26 into the sealing cover 12. The insert rod 26 pushes the connecting frame 222 to slide towards the buckle plate 2313. Then, the connecting frame 222 pushes the buckle plate 2313 to rotate along the outer surface of the buckle plate 2313. While the buckle plate 2313 rotates, it squeezes the first spring 2314 until the buckle plate 2313 opens. Then, the first spring 2314 squeezes the buckle plate 2313 to reset, thus locking the connecting frame 222.

[0049] like Figures 3 to 6As shown, as an optional embodiment: the inflation assembly 24 includes a compressed air tank 241 disposed in the inner cavity of the sealing cover 12, a pressing valve 242 disposed below the control end of the locking assembly 231, and a first connecting pipe 243 disposed between the compressed air tank 241 and the pressing valve 242;

[0050] The press valve 242 is connected to the air outlet pipe 25.

[0051] It should be noted that a compressed air tank 241 is vertically mounted on the sealing cover 12. The compressed air tank 241 and the sealing cover 12 are threaded together, and the sealing cover 12 is provided with a connector that is compatible with the compressed air tank 241. A pressing valve 242 is provided below the push plate 2312. The compressed air tank 241 and the pressing valve 242 are connected by a first connecting pipe 243. The air outlet end of the pressing valve 242 is connected to one end of the air outlet pipe 25.

[0052] In use, when the thumb switch 232 presses the push plate 2312 to cause the buckle plate 2313 to be misaligned with the connecting frame 222, after a pause of 2-5 seconds, the thumb switch 232 continues to push the push plate 2312 downward, pushing the push plate 2312 to squeeze the press valve 242, and introduce compressed gas into the airbag 27 to inflate the airbag 27.

[0053] like Figures 1 to 7 As shown, as an optional embodiment: the inner cavity of the sealing cover 12 is provided with a vertical plate 121, which divides the inner cavity of the sealing cover 12 into a working cavity and a cable management cavity, and the cable management cavity is provided with a cable management assembly 3.

[0054] The cable management assembly 3 includes a fixing frame 31 disposed on the inner wall of the cable management cavity, a take-up reel 32 disposed on the fixing frame 31, a rotary joint 33 and a rotating component 34 disposed at both ends of the take-up reel 32, and a connecting plug 35 disposed on the take-up reel 32.

[0055] The rotating component 34 includes a connecting rod 341 disposed at one end of the take-up reel 32, and a knob 342 disposed at one end of the connecting rod 341.

[0056] It should be noted that the inner cavity of the sealing cover 12 is fixedly connected to the upright plate 121. The upright plate 121 divides the inner cavity of the sealing cover 12 into a working cavity and a cable management cavity. The excess part of the vent pipe 25 is placed in the cable management cavity to prevent the excess part from interfering with the structural operation in the working cavity. The excess vent pipe 25 is organized and stored by the cable management assembly 3. The vent pipe 25 passes through the upright plate 121 and is slidably connected to it.

[0057] The fixing frame 31 is fixedly installed inside the cable management cavity. A take-up reel 32 is rotatably connected to the fixing frame 31. One end of the take-up reel 32 is fixedly connected to the rotating end of the rotary joint 33. A connecting rod 341 is fixedly connected to the other end of the take-up reel 32. The connecting rod 341 passes through the sealing cover 12. A knob 342 is fixedly connected to one end of the connecting rod 341. A connecting plug 35 is fixedly connected to the take-up reel 32. The take-up reel 32 is a hollow cavity. The hollow cavity, the connecting plug 35 and the rotary joint 33 are connected. The pressing valve 242 is connected to the rotary joint 33. The air outlet pipe 25 is connected to the connecting plug 35 and is wound on the take-up reel 32. By rotating the knob 342, the connecting rod 341 is rotated, which in turn drives the take-up reel 32 to rotate, thereby achieving the winding of the air outlet pipe 25.

[0058] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
