Description

Technical Field

[0001] The present invention relates to the technical field of water sampling, and specifically to a groundwater detection and sampling device. Background Technique

[0002] A groundwater sampling device is a tool specifically used for extracting groundwater samples, and is widely used in fields such as groundwater environmental monitoring, exploitation and utilization of groundwater resources, environmental pollution investigation, and hydrological research;

[0003] When detecting and sampling groundwater, generally, the staff will place a sampling tube with a piston into the groundwater, then pull the piston to rise inside the sampling tube so that the water body enters the sampling tube, take out the sampling tube from the groundwater, and then detect the sampled water body to complete the purpose of sampling. Since the length of the sampling tube is relatively long and the sampling port is at the bottom of the sampling tube, when sampling groundwater, the groundwater can only enter the sampling tube through the sampling port alone, and the area of the water body to be sampled is relatively concentrated at the sampling port, making it inconvenient to sample the water bodies in other areas. At the same time, it will affect the sampling efficiency and the continuity and accuracy of subsequent sampling and detection, with relatively low limitations. Summary of the Invention

[0024] Further, the blocking mechanism includes a piston rod one slidably connected inside the piston groove two, and the top of the piston rod one slides through to the inside of the sampling tube;

[0027] Further, the sliding component includes a sliding ring slidably connected inside the piston groove one, and a piston rod two slides through the side wall of the sliding ring;

[0032] Furthermore, the movable component includes a second piston disc fixedly connected to the bottom of the rubber ring. The second piston disc is slidably connected to the outer surface of the long rod located at the bottom of the first piston disc.

[0033] A number of cylindrical grooves are formed in the inner wall of the second piston disc. A first communication groove is formed at the top of the cylindrical groove, and a one-way plate is rotatably connected inside the first communication groove.

[0036] One end of the inclined frame away from the spring disc is fixedly connected to a triangular plate, and a through groove is formed at the top of the triangular plate.

[0037] The present invention has the following beneficial effects:

[0038] 1. In the present invention, through the movable component and the fixing component, when the long rod drives the second piston disc to continue moving upward, the upward movement of the second piston disc will push the inclined ring to slide upward. At this time, the groundwater outside the sampling pipe will no longer enter the sampling pipe through the round hole at the bottom of the sampling pipe. At the same time, since the second piston disc is blocked by the inclined ring, when the long rod is continuously pulled, the elastic plate will be deformed and contracted after being squeezed by the second piston disc. At this time, when the long rod is continuously pulled, it will be separated from the second piston disc and drive the first piston disc to continue sliding upward in the narrow channel inside the sampling pipe. At this time, the continuous sliding of the first piston disc will pump the groundwater in the outer peripheral area in the middle of the sampling pipe through the water inlet pipe. When sampling the groundwater at the outer bottom and the middle area of the sampling pipe respectively by the first piston disc and the second piston disc, the layered sampling of the groundwater outside the sampling pipe can be completed, which can reduce the limitation of single-area sampling during sampling, improve the sampling efficiency, and at the same time improve the continuity and accuracy of subsequent groundwater detection.

[0039] 2. In the present invention, through the movable component and the opening and closing component, when the long rod separates from the second piston disk, the spring disks inside the multiple cylindrical grooves will push the inclined frame and the triangular plate to slide under the release of the elastic potential energy of their own springs. When the multiple spring disks and the triangular plates slide, the multiple triangular plates will close at the bottom of the second piston disk. At this time, the closed triangular plates will seal the bottom of the second piston disk. Through the closing of the multiple triangular plates and the sealing of the rubber ring, it is possible to reduce the situation where the groundwater in the wider and narrower parts of the sampling tube is mixed when sampling the water source outside the sampling tube. Through the blocking of the second piston disk and the closed triangular plates between the groundwater sampled in the wider and narrower parts, it is possible to prevent the mixing of water bodies while ensuring the independence of the water body after sampling, reducing the influence of the mixing of water bodies on the accuracy of subsequent detection, and thus ensuring the representativeness of the sample after sampling.

[0040] 3. In the present invention, through the movable component and the storage component, when the spring disk slides, it will extract the residual gas between the bottom of the second piston disk and the sampling tube through the opening of the second one-way plate, so that the residual gas in the sampling tube when the water body enters will enter into the multiple cylindrical grooves. Furthermore, it is possible to reduce the situation where gas remains due to the space between the second piston disk and the bottom of the sampling tube when sucking, reducing the situation where the water sampling volume after water sampling does not match the actual situation due to the occupation of part of the space in the sampling tube by the residual gas. At the same time, by reducing the residual gas, it is also possible to reduce the mixing between gas and water body during sampling, thereby affecting the water quality and purity of the sample, improving the sampling accuracy and stability while ensuring the purity of the sample.

[0041] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Please refer to Figures 1 - 11 As shown in the figure, the present invention is a groundwater detection and sampling device, including a main body 1, inside which a water level sensor 101 is fixedly connected, and further including;

[0058] The sliding mechanism 2 is installed inside the main body 1 and is used for sampling water sources.

[0059] The auxiliary mechanism 3 is installed on the outer surface of the sliding mechanism 2 and is used to prevent the mixing of water sources.

[0060] After the sliding mechanism 2 sucks the water source into the main body 1, the auxiliary mechanism 3 can block the water sources in the upper and lower regions inside the main body 1.

[0061] The main body 1 includes:

[0062] The storage component 11 is installed at the bottom of the main body 1 through a fixing part.

[0063] The blocking component 12 is installed inside the storage component 11.

[0064] The sliding component 13 is installed inside the storage component 11.

[0065] The sliding mechanism 2 includes a long rod 201 that slides through the side wall of the main body 1. The sliding mechanism 2 includes:

[0066] The fixing component 21 is installed at the bottom of the long rod 201.

[0067] The auxiliary mechanism 3 includes a rubber ring 301 arranged on the outer surface of the long rod 201. The auxiliary mechanism 3 includes:

[0068] The movable component 31 is installed at the bottom of the rubber ring 301.

[0069] The opening and closing component 32 is installed inside the movable component 31.

[0070] The fixing part includes a sampling pipe 111 bolted to the bottom of the main body 1. A water inlet pipe 112 is fixedly connected to the outer surface of the sampling pipe 111. A round hole is opened at the bottom of the sampling pipe 111.

[0071] The storage component 11 includes a plurality of long grooves 113 opened inside the sampling pipe 111. The plurality of long grooves 113 are arranged in a circular axis array centered on the middle part of the sampling pipe 111.

[0072] A plurality of piston grooves one 114 and a plurality of piston grooves two 115 are opened inside the sampling pipe 111.

[0073] The piston groove one 114 is communicated with the piston groove two 115 through the long groove 113.

[0074] A first stop block is fixedly connected inside the first piston groove 114, and a second stop block is fixedly connected inside the second piston groove 115. The inner cavity part of the sampling pipe 111 is in a state of being narrower at the top and wider at the bottom, presenting a state as shown in Figure 11 When the long rod 201 drives the second piston disc 311 to rise, a negative pressure will be generated in the sampling pipe 111. At this time, the formation of the negative pressure will drive the blocking disc 122 to rise through the adsorption force and suck the groundwater outside the sampling pipe 111, so that the groundwater enters the sampling pipe 111 through the round hole at the bottom of the sampling pipe 111.

[0075] The blocking assembly 12 includes a first piston rod 121 slidably connected inside the second piston groove 115, and the top of the first piston rod 121 slidably penetrates into the sampling pipe 111;

[0076] A return spring is fixedly connected to the inner wall of the bottom of the first piston rod 121, and the top of the return spring is fixedly connected to the inner wall of the top of the second piston groove 115;

[0077] A plurality of the tops of the first piston rods 121 are fixedly connected with a blocking disc 122, and a top rod 123 is fixedly connected to the bottom of the blocking disc 122. The sliding of the blocking disc 122 will drive a plurality of the first piston rods 121 to slide synchronously. When the plurality of the first piston rods 121 slide, they will squeeze the gas in the second piston groove 115 and make the squeezed gas enter the first piston groove 114 through the long groove 113.

[0078] The sliding assembly 13 includes a sliding ring 131 slidably connected inside the first piston groove 114, and a second piston rod 132 slidably penetrates through the side wall of the sliding ring 131;

[0079] An auxiliary spring is fixedly connected to the bottom of the sliding ring 131 on the outer surface of the second piston rod 132;

[0080] A plurality of the bottoms of the second piston rods 132 are fixedly connected with an inclined ring 133. The bottom of the auxiliary spring is fixedly connected to the outer surface of the second piston rod 132. When the squeezed gas enters the first piston groove 114, it will push the sliding ring 131 to slide downward. When the sliding ring 131 slides, it will drive the second piston rod 132 and the inclined ring 133 to move downward synchronously through the auxiliary spring.

[0081] Three rectangular grooves are formed on the outer surface of the long rod 201;

[0082] The fixing assembly 21 includes a first piston disc 211 fixedly connected to the outer surface of the long rod 201. An elastic plate 212 is arranged inside the rectangular groove, and the top of the elastic plate 212 is fixedly connected to the inner wall of the top of the rectangular groove. When the long rod 201 is continuously pulled, it will be separated from the second piston disc 311 and drive the first piston disc 211 to continue to slide upward in the narrower channel of the sampling pipe 111.

[0083] The movable component 31 includes a second piston disc 311 fixedly connected to the bottom of the rubber ring 301, and the second piston disc 311 is slidably connected to the outer surface of the long rod 201 at the bottom of the first piston disc 211;

[0084] A plurality of cylindrical grooves 312 are formed in the inner wall of the second piston disc 311, a first communication groove 313 is formed at the top of the cylindrical groove 312, and a one-way plate is rotatably connected inside the first communication groove 313;

[0085] A second communication groove 314 is formed at the bottom of the cylindrical groove 312, a second one-way plate is rotatably connected inside the second communication groove 314. When the long rod 201 continues to move upward after being pulled, it will be separated from the second piston disc 311. When the long rod 201 is separated from the second piston disc 311, the auxiliary springs on the plurality of second piston rods 132 will push the inclined ring 133 to move downward for a certain distance.

[0086] The opening and closing component 32 includes a spring disc 321 fixedly connected to the inner wall of the cylindrical groove 312 on the side away from the long rod 201, and an inclined frame 322 is fixedly connected to the side wall of the spring disc 321;

[0087] One end of the inclined frame 322 away from the spring disc 321 is fixedly connected to a triangular plate 323, and a through groove is formed at the top of the triangular plate 323.

[0088] During use, first, external staff connect two pull ropes to the top of the main body 1 and the top of the long rod 201 respectively. Then, the staff drags the two ropes and transports this device into the groundwater. When the main body 1 is completely immersed in water and the water level sensor 101 detects the groundwater, it will transmit a signal to the outside. At this time, after the staff receives the signal, they stop transporting the main body 1 in the groundwater. Then, the staff pulls the pull rope connected to the long rod 201, so that the long rod 201 drives the first piston disc 211 and the second piston disc 311 to slide upward in the sampling tube 111. At this time, the upward movement of the second piston disc 311 and the first piston disc 211 will suck the groundwater outside the sampling tube 111 into the sampling tube 111 through the round hole at the bottom of the sampling tube 111. Then, the main body 1 is pulled back to the ground to complete the purpose of sampling before detection. When the elastic potential energy on the spring disc 321 is released and pushes the spring disc 321 and the inclined frame 322 to slide, the sliding of the spring disc 321 and the inclined frame 322 in the cylindrical groove 312 will generate negative pressure in the cylindrical groove 312.

[0089] When the staff pulls the pull rope connected to the long rod 201 and causes the long rod 201 to rise in the sampling tube 111, since multiple elastic plates 212 on the long rod 201 are stuck at the bottom of the second piston disk 311, when the long rod 201 rises, it will drive the first piston disk 211 and the second piston disk 311 to rise synchronously in the sampling tube 111. When the long rod 201 drives the second piston disk 311 to rise, a negative pressure will be generated in the sampling tube 111. At this time, the formation of the negative pressure will drive the blocking disk 122 to rise through the adsorption force and suck the groundwater outside the sampling tube 111, so that the groundwater enters the sampling tube 111 through the round hole at the bottom of the sampling tube 111. At the same time, when the blocking disk 122 slides under the pushing action of the negative pressure and the inflow of water, the sliding of the blocking disk 122 will drive multiple first piston rods 121 to slide synchronously. When the multiple first piston rods 121 slide, they will squeeze the gas in the second piston groove 115 and make the squeezed gas enter the first piston groove 114 through the long groove 113. When the squeezed gas enters the first piston groove 114, it will push the sliding ring 131 to slide downward. When the sliding ring 131 slides, it will drive the second piston rod 132 and the inclined ring 133 to move downward synchronously through the auxiliary spring. At the same time, when the second piston disk 311 continuously extracts the external groundwater and is about to move to the junction of the wider and narrower channels in the sampling tube 111, the upward movement of the second piston disk 311 will make the rubber ring 301 contact the side wall of the inclined ring 133. Subsequently, when the long rod 201 drives the second piston disk 311 to continue to move upward, the upward movement of the second piston disk 311 will push the inclined ring 133 to slide upward. At this time, the groundwater outside the sampling tube 111 will no longer enter the sampling tube 111 through the round hole at the bottom of the sampling tube 111. At this time, when the inclined ring 133 is pushed to slide upward, it will push the sliding ring 131 to squeeze the gas in the first piston groove 114 through the auxiliary spring and make it enter the second piston groove 115 to push the first piston rod 121 to reset. The reset spring on the first piston rod 121 will also push the first piston rod 121 to reset under the action of its own elastic potential energy. At the same time, since the second piston disk 311 is blocked by the inclined ring 133, when the long rod 201 is continuously pulled, the elastic plate 212 will be deformed and contracted after being squeezed by the second piston disk 311. At this time, when the long rod 201 is continuously pulled, it will be separated from the second piston disk 311 and drive the first piston disk 211 to continue to slide upward in the narrower channel of the sampling tube 111. At this time, the continuous sliding of the first piston disk 211 will extract the groundwater in the outer peripheral area of the middle part of the sampling tube 111 through the water inlet pipe 112. By sampling the groundwater outside the sampling tube 111, at the bottom and in the middle area respectively with the first piston disk 211 and the second piston disk 311, the layered sampling of the groundwater outside the sampling tube 111 can be completed, which can reduce the limitation of single-area sampling during sampling, improve the sampling efficiency, and at the same time improve the continuity and accuracy of subsequent groundwater detection.

[0090] When the upward movement of the second piston disc 311 presses against the inclined ring 133 and is blocked by the inclined ring 133, when the long rod 201 is pulled and continues to move upward, it will separate from the second piston disc 311. When the long rod 201 separates from the second piston disc 311, the auxiliary springs on the plurality of second piston rods 132 will push the inclined ring 133 to move downward a certain distance. When the inclined ring 133 continues to move downward, it will push the rubber ring 301 and the second piston disc 311 downward. Since there is groundwater sucked at the bottom of the second piston disc 311, when the second piston disc 311 and the rubber ring 301 are pushed by the inclined ring 133, the inclined ring 133 will closely fit with the rubber ring 301. At this time, the rubber ring 301 can seal between the second piston disc 311, the inclined ring 133 and the relatively wide inner wall of the sampling tube 111. At the same time, when the long rod 201 separates from the second piston disc 311, the spring discs 321 inside the plurality of cylindrical grooves 312 will push the inclined frames 322 and the triangular plates 323 to slide under the release of their own spring elastic potential energy. When the plurality of spring discs 321 and the triangular plates 323 slide, the plurality of triangular plates 323 will close at the bottom of the second piston disc 311. At this time, the closed triangular plates 323 will seal the bottom of the second piston disc 311. Through the closing of the plurality of triangular plates 323 and the sealing of the rubber ring 301, it is possible to reduce the mixing of groundwater in the wider and narrower parts of the sampling tube 111 when sampling the water source outside the sampling tube 111. Through the blockage of the second piston disc 311 and the closed triangular plates 323 between the sampled groundwater in the wider and narrower parts, it is possible to prevent water body mixing while ensuring the independence of the water body after sampling, reducing the impact of water body mixing on the accuracy of subsequent detection, and thus ensuring the representativeness of the sample after sampling.

[0091] When the spring potential energy on the spring disc 321 is released and pushes the spring disc 321 and the inclined frame 322 to slide, the sliding of the spring disc 321 and the inclined frame 322 in the cylindrical groove 312 will generate negative pressure in the cylindrical groove 312. At this time, the formation of the negative pressure will cause the one-way plate two in the communication groove two 314 to open and the one-way plate in the communication groove one 313 to close. When the spring disc 321 slides, it will extract the residual gas between the bottom of the second piston disc 311 and the sampling tube 111 through the opening of the one-way plate two and the through grooves on the triangular plate 323, so that the residual gas in the sampling tube 111 when the water body enters enters into the plurality of cylindrical grooves 312, thereby reducing the situation of gas residue when the subsequent water body enters due to the space between the second piston disc 311 and the bottom of the sampling tube 111, reducing the situation that the water sampling volume after water sampling does not match the actual situation due to the occupation of part of the space in the sampling tube 111 by the gas residue. At the same time, by reducing the gas residue, it is also possible to reduce the mixing between the gas and the water body during sampling, thereby affecting the water quality and purity of the sample, improving the sampling accuracy and stability while ensuring the purity of the sample.
