Description

Technical Field

[0001] The present application relates to the field of geological exploration technology, and in particular to a groundwater level detection and collection device for hydrogeological exploration. Background Art

[0002] At present, hydrogeology, a branch of geology, refers to the various changes and movement phenomena of groundwater in nature; hydrogeology is the science of studying groundwater. It mainly studies the distribution and formation laws of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational use, the adverse effects of groundwater on engineering construction and mining and their prevention and control, etc. With the development of science and the needs of production and construction, hydrogeology is divided into branch disciplines such as regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, ore deposit hydrogeology, and soil improvement hydrogeology; in hydrogeological detection operations, it is necessary to use the groundwater level detector in the existing technology to detect the groundwater level. Usually, it is necessary to dig a detection hole with a known diameter from the ground to the bottom in advance to connect with the groundwater flow, and then slowly penetrate the groundwater level detector into the detection hole until the groundwater level is detected, and then the groundwater level can be known based on the wirelessly transmitted electrical signal.

[0003] In the process of placing the detector into the detection hole, since the ground personnel do not know the approximate water level information of the groundwater, they need to use a reel to place the detector into the groundwater surface and float it on the water surface. Since the reel is generally a soft rope and the groundwater surface is wide, the detector will float up and down to a certain extent on the water surface. When placed in the hole with the soft rope, the soft rope may also exert some downward pressure on the detector, causing the detection part of the detector to be unable to accurately sense the water surface position, thereby affecting the measurement accuracy. At the same time, after the detector is placed on the water surface in a conventional manner, when measurement is not needed, the detector needs to be taken out manually to avoid the detector always being in a working state. The detector needs to be put down again for data measurement when it is used next time, which is very inconvenient.

[0004] Regarding the above-mentioned related technologies, the applicant believes that there are technical defects such as inconvenience in use and inaccurate measurement. Summary of the invention

[0005] In order to solve the above technical problems, the present application provides a groundwater level detection and collection device for hydrogeological exploration.

[0006] The present application provides a groundwater level detection collector for hydrogeological exploration, which adopts the following technical solution:

[0007] The water level detection and collection device according to claim 1, wherein the water level detection and collection device comprises a water level information collection component which is sleeved on the water level detection and collection component and can move relative to the extension direction of the water level detection and collection component. The water level detection and collection component comprises an information collection component and a cleaning component which is located at the lower side of the information collection component. The cleaning component can slide freely vertically relative to the information collection component. A vertical supporting sleeve is arranged inside the information collection component. The cleaning component is fixedly connected with a driving rod corresponding to the position of the supporting sleeve. A positioning block is fixedly connected with the top of the driving sleeve to prevent the cleaning component from detaching from the supporting sleeve. A driving slider is freely slidable in the supporting sleeve at the upper part of the driving rod. A sliding groove is provided on the side of the supporting sleeve corresponding to the moving range of the driving slider. The top of the sliding groove is hinged with a supporting rod. A connecting rod is arranged between the driving slider and the supporting rod. One end of the connecting rod is hinged to the driving slider, and the other end of the connecting rod is hinged at the middle position of the supporting rod.

[0008] By adopting the above technical scheme, the information collection component for collecting groundwater level information is placed downward by winding the rope. At this time, the cleaning component located at the lower side of the information collection component will first contact the surface of the groundwater. When the cleaning component contacts, it will float on the water surface. At this time, the information collection component located at the upper side of the cleaning component will continue to move downward, and the driving rod fixedly connected to the cleaning component will move upward relative to the information collection component and resist the driving slider. The driving slider will move upward in the supporting sleeve, and the driving slider will drive the supporting rod to unfold through the connecting rod, so that the outer end of the supporting rod is supported and fixed on the inner wall of the detection hole, thereby controlling the information collection component to stop above the surface of the groundwater, so as to facilitate the next step of water surface information collection. In this way, the information collection component can be stably fixed so that it will not shake, thereby improving the measurement accuracy. At the same time, this method can be stably fixed by mechanical means without increasing the cost of electrical control and can be placed without contacting the water surface for a long time without being taken out many times.

[0009] Preferably, the cleaning assembly includes a cleaning frame with a lower opening, the cleaning frame is slidably connected to the winding rope, and a positioning ring slidably connected to the winding rope is provided on the lower side of the cleaning frame, and multiple groups of hinged rods are provided between the cleaning frame and the positioning ring, one end of the hinged rod is hinged to the lower edge position of the cleaning frame, and the other end of the hinged rod is hinged to the outer ring surface of the positioning ring.

[0010] By adopting the above technical solution, since the information collection component may be in a cubic shape, when it is placed in the detection hole, the uneven position of the inner wall of the detection hole may damage the information collection component, so a positioning ring and a hinged rod are provided. At this time, the cleaning component has an overall conical structure, and the cleaning component acts as a counterweight, and it is easier to place it into the detection hole.

[0012] By adopting the above technical solution, the hinged rod is a telescopic rod. When the cleaning frame is gradually lowered, the cleaning frame and the hinged rod form a cone structure, which is convenient for being placed in the detection hole. When the groove of the lower hinged rod contacts the surface of the groundwater, the hinged rod will shrink under the action of buoyancy. At this time, the positioning ring will move upward, so that the whole body forms a downward groove, which is convenient for capturing floating objects on the surface of the groundwater.

[0013] Preferably, a positioning chamber is provided on the positioning sleeve on the upper side of the positioning ring, and a limiting groove is provided on the outer side of the positioning chamber. The locking assembly includes a triangular block arranged in the positioning chamber, and the triangular block can protrude from the limiting groove to prevent the positioning ring from moving upward. A spring is arranged in the positioning chamber, and the triangular block is located in the positioning chamber and is fixedly connected to a limiting plate, one end of the spring is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the positioning sleeve. The triangular block pops out of the limiting groove under the action of the spring.

[0014] By adopting the above technical solution, the triangular block is set up so that the articulated rod with telescopic performance will not shorten when the cleaning component moves downward in the detection hole. When the cleaning component falls on the water surface, due to its strong buoyancy, the articulated rod with telescopic performance will shrink, and then the positioning ring will move upward, so that the whole forms a downward notch.

[0015] Preferably, the information collection component includes an information collection box and a water level detector, the information collection box is provided with a collection sleeve which vertically penetrates the information collection box, the water level detector includes a detection sleeve, the upper and lower ends of the detection sleeve are fixedly connected with a filter plate, a freely movable detector is provided in the detection sleeve, and the detection sleeve is slidably connected in the collection sleeve.

At this time, the cleaning component can push any floating objects that may exist on the lower side below the water surface to prevent the floating objects from affecting the measurement results.

[0020] By adopting the above technical solution, a first limit groove is set on the driving slider. Before the electric cylinder is started, the first limit block can be driven by the limit cylinder to contact the side of the driving slider, so that when the driving rod moves downward, the support rod can also play a supporting role. At the same time, the limit cylinder and the first limit block are set, so that the support rod has stronger stability when the cleaning component is not pushed.

[0021] Preferably, a second limiting block is fixedly connected to the piston rod of the limiting cylinder, and a second limiting groove is provided on the side of the collecting sleeve.

[0022] By adopting the above technical solution, a second limit block is arranged on the piston rod of the limit cylinder. Under normal conditions, the second limit block will abut against the side of the detection sleeve, so that the detection sleeve will not fall. When water level monitoring is required, the limit cylinder can be controlled to move and abut against the side of the driving slider.

[0039] Reference Figure 2 and Figure 3 Specifically, a plurality of groups of vertical support sleeves 22 are arranged on the information collection component 2, the upper part of the support sleeve 22 is in a closed state, a slide groove is provided at the side position of the support sleeve 22, a support rod 23 is hingedly connected to the upper end of the side of the information collection component 2 at the slide groove, an anti-slip member is fixedly connected to the outer end of the support rod 23, a driving slider 221 is freely slidably connected vertically in the support sleeve 22, a connecting rod 231 is arranged between the support rod 23 and the driving slider 221, and one end of the connecting rod 231 is hingedly connected to the driving slider 221.

The driving slider 221 can be preliminarily fixed by the cooperation of the strong magnet and the electromagnet assembly.

[0040] When the support rod 23 is in a state of being in contact with the information collection component 2, the driving slider 221 is located at the lower position of the support sleeve 22. When the support rod 23 is in a state of supporting the detection hole to stably fix the information collection component 2, the driving slider 221 is located on the upper side of the support sleeve 22. At this time, the electromagnet component can be turned on to position the driving slider 221 at the upper part through the strong magnetic adsorption effect. Therefore, when the cleaning component 3 first contacts the surface of the groundwater, the cleaning component 3 stops moving downward. At this time, the information collection component 2 will continue to move downward. At this time, the positioning block at the upper end of the driving rod 311 will control the driving slider 221 to move upward, thereby driving the support rod 23 to expand and support on the inner wall of the detection hole, thereby realizing the stable fixation of the information collection component 2.

[0043] A limit cylinder 27 is provided at the position where the support sleeve 22 and the collection sleeve 254 are located. The base of the limit cylinder 27 is fixed on the inner wall of the information collection box 21. The piston rod of the limit cylinder 27 is fixedly connected with a first limit block 271 and a second limit block 272. A first limit groove 224 is provided at the position of the side of the support sleeve 22 corresponding to the first connection block. The first limit block 271 can extend from the first limit groove 224 into the support sleeve 22 and abut against the driving slider 22. 1; a second limiting groove 2541 is provided on the side of the collection sleeve 254 at a position corresponding to the second limiting block 272, and the second limiting block 272 can extend from the second limiting groove 2541 into the collection sleeve 254 and abut against the side of the detection sleeve 251; the first limiting groove 224 and the second limiting groove 2541 are provided at relative positions, so that when the first limiting block 271 abuts against the side of the driving slider 221, the second limiting block 272 is separated from the side of the detection sleeve 251.

[0044] Reference Figure 4 and Figure 5 The cleaning assembly 3 includes a cleaning frame 31 with a lower opening, a bearing groove 32 for receiving the detection sleeve 251 is provided at the upper part of the cleaning frame 31 corresponding to the position of the detection sleeve 251, and a guide rod 255 is fixedly connected to the side of the bearing groove 32, and a guide groove 256 adapted to the guide rod 255 is provided at the position corresponding to the guide rod 255 on the detection sleeve 251. The cleaning frame 31 is slidably connected to the winding rope 1, and a positioning sleeve 33 is fixedly connected below the middle position of the cleaning frame 31. The positioning sleeve 33 is sleeved on the winding rope 1, and a positioning ring 35 is sleeved on the positioning sleeve 33. A plurality of sets of hinged rods 331 are arranged between the positioning ring 35 and the outer edge of the lower side of the cleaning frame 31. The hinged rod 331 is a telescopic rod and has a downward notch. One end of the hinged rod 331 is hingedly connected to the lower edge of the cleaning frame 31, and the other end is hingedly connected to the outer ring surface of the positioning ring 35; between the positioning sleeve 33 and the positioning ring 35 The locking assembly 34 is provided to relatively fix the two, and a positioning chamber is provided on the positioning sleeve 33 on the upper side of the positioning ring 35, and a limiting groove 341 is provided on the outer side of the positioning chamber.

The triangular block 342 pops out of the limiting groove 341 under the action of the spring 343, so that the positioning ring 35 does not move upward when falling downward, but when the hinged rod 331 contacts the water surface and continues to move downward, it has a strong buoyancy, and at this time the triangular block 342 cannot limit the upward movement of the positioning ring 35.

[0045] How this application works is:

[0046] When it is necessary to measure the groundwater level, a tensioning device can be pre-set so that the two sets of rotating rollers 24 can clamp the rope 1, so that the water level information collection component will not fall along the rope 1 at a very high speed, and the drive motor does not intervene at this time; when the hinged rod 331 located on the lower side of the cleaning frame 31 contacts the water surface, the triangular block 342 cannot limit the positioning ring 35, and the positioning ring 35 moves upward and is collected in the lower groove of the cleaning frame 31.

[0047] When the cleaning frame 31 contacts the surface of the groundwater, the cleaning frame 31 will float on the water surface, and the cleaning frame 31 will buckle the floating objects on the water surface located at the lower side of the cleaning frame 31. At this time, the information collection box 21 will continue to move downward. At this time, the positioning block on the top of the driving rod 311 will abut against the lower part of the driving slider 221, controlling the driving slider 221 to move upward. The upward movement of the driving slider 221 will drive the connecting rod 231 to move, and then drive the support rod 23 to unfold, so that the support rod 23 is supported on the inner wall of the detection hole. At this time, the information collection box 21 is stably fixed on the upper side of the water surface, and the electromagnetic group The cooperation of the parts and the strong magnet fixes the position of the driving slider 221; then the limit cylinder 27 and the electric cylinder 261 are started by different control, and the piston rod of the electric cylinder 261 is extended to push the cleaning frame 31 downward to below the water surface. At this time, the second limit block 272 on the limit cylinder 27 is separated from the detection sleeve 251, and the detection sleeve 251 falls into the bearing groove 32 to measure the water level data. Since the floating objects on the water surface are pushed underwater by the cleaning frame 31 at this time, the measurement is more accurate. At the same time, the first limit block 271 abuts against the side of the driving slider 221, thereby achieving more stable support.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
