Description

Technical Field

[0001] This application relates to the technical field of water quality monitoring and sampling, and more specifically, to an underground space water quality monitoring and sampling device. Background Art

[0002] Groundwater resources are more complex than surface water. The changes in the quality and quantity of groundwater itself, as well as the environmental conditions that cause groundwater changes and the migration law of groundwater, cannot be directly observed. At the same time, groundwater pollution and land subsidence caused by groundwater overexploitation are slow-changing types. Once accumulated to a certain extent, they become irreversible damage. Therefore, to accurately develop and protect groundwater, long-term groundwater monitoring must be relied on to timely grasp the dynamic changes. The important indicators for measuring groundwater resources are the changes in water quality, water level, and water temperature. The change in groundwater quality is an important monitoring indicator for groundwater pollution. The change in groundwater level is closely related to the groundwater extraction volume and land subsidence, and it has important significance for discovering and controlling land subsidence.

[0003] When sampling, usually, staff members put the sampling equipment into the groundwater for sampling. Such a sampling method can only take one sample at one sampling point, and the sample taken has strong contingency and is not representative. Moreover, after sampling, the sampling pipe cannot be sealed, resulting in the sampling sample being easily contaminated, affecting the accuracy of monitoring. In addition, the sampling pipe of the existing sampling equipment is exposed outside the equipment, and when the sampling equipment enters and exits the underground space, the sampling pipe is easily collided with the stones in the underground space, resulting in damage to the sampling pipe. To solve the above problems, a sampling device for underground water quality monitoring needs to be designed. Summary of the Invention

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0023] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0024] Next, a groundwater quality monitoring and sampling device according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0025] Please refer to Figures 1 to 9 , a groundwater quality monitoring and sampling device according to an embodiment of the present application includes: A protective sleeve 1, with movable grooves 11 evenly formed at the upper and lower ends of the outer side wall of the protective sleeve 1. A sampling installation assembly 2 is provided at a position above the movable groove 11 on the inner wall of the protective sleeve 1. A sampling tube 3 is installed on the sampling installation assembly 2. A sealing assembly 7 is installed in the sampling tube 3. An automatic opening assembly 4 is installed on the upper side of the end of the sampling tube 3; The upper end of the protective sleeve 1 is provided with an opening, and a sampling driving assembly is vertically installed inside the protective sleeve 1 corresponding to the opening position.

[0026] In this embodiment, by installing the sampling tube 3 on the sampling installation assembly 2, and the sampling installation assembly 2 can rotate under the action of the sampling driving assembly, the sampling tube 3 can be rotated out of the protective sleeve 1 during sampling and rotated into the protective sleeve 1 after sampling is completed, preventing the sampling tube from being damaged during the process of entering or taking out the sampling device. Moreover, a plurality of sampling installation assemblies 2 are installed on the protective sleeve 1, enabling the sampling device to collect multiple samples at one sampling point during sampling, improving the accuracy of water quality monitoring.

[0027] By providing the automatic opening assembly 4, when the sampling tube 3 rotates out of the protective sleeve 1, the automatic opening assembly 4 can automatically squeeze the sealing assembly 7 in the sampling tube 3 to one side, opening the opening at the end of the sampling tube 3 so that groundwater can enter the sampling tube 3 for water quality sampling. When sampling is completed and the sampling tube 3 is retracted into the protective sleeve 1, the spherical airbag 75 in the sealing assembly 7 is filled with gas, and the spherical airbag 75 can block the end of the sampling tube 3, preventing the sample in the sampling tube 3 from leaking and preventing the sample from being contaminated.

[0028] In use, the self-gravity of the sampling driving component can drive the unfolding and sampling action of the sampling tube 3 and can drive the opening of the port of the sampling tube 3. After sampling, the sampling driving component can simultaneously retract the sampling tube 3 and close the port of the sampling tube 3, achieving one-step operation, reducing the structural complexity caused by separate control of the two, and making the operation simpler.

[0029] Please refer to Figures 2 - 4 , the sampling installation component 2 includes a Z-shaped mounting plate 21 and an L-shaped rotating plate 22. The Z-shaped mounting plate 21 is fixedly installed above the movable groove 11 on the inner wall of the protective sleeve 1. One end of the Z-shaped mounting plate 21 in contact with the inner wall of the protective sleeve 1 is lower than the other end of the Z-shaped mounting plate 21. An L-shaped rotating plate 22 is rotatably installed on the lower surface of the end of the Z-shaped mounting plate 21 close to the protective sleeve 1. A sampling tube 3 is fixedly installed on the L-shaped rotating plate 22. A driving chute 23 is formed in the long end of the L-shaped rotating plate 22. The L-shaped rotating plate 22 can rotate on the lower side of the Z-shaped mounting plate 21. Therefore, when the L-shaped rotating plate 22 rotates, it can drive the sampling tube 3 to rotate, so that the sampling tube 3 can rotate out of the protective sleeve 1 during sampling and rotate into the protective sleeve 1 after sampling.

[0030] The sampling driving component includes a driving rod 5, a counterweight 51, a first pulling rope 52, and a first pulling handle 53. The driving rod 5 is vertically arranged on the central axis of the protective sleeve 1. A counterweight 51 is fixedly connected to the lower end of the driving rod 5. A first pulling rope 52 is fixedly connected to the upper end of the driving rod 5. The upper end of the first pulling rope 52 is connected to a first pulling handle 53. A driving frame 54 is fixedly installed on the side wall of the driving rod 5 corresponding to the position of the L-shaped rotating plate 22. The driving frame 54 movably penetrates through the driving chute 23. By pulling up the first pulling handle 53 on the first pulling rope 52, the driving rod 5 can be moved upward. During the upward movement of the driving rod 5, the driving frame 54 arranged on the side wall of the driving rod 5 can drive one end of the L-shaped rotating plate 22 to rotate upward, so that the sampling installation component 2 can rotate into the protective sleeve 1, and the sampling tube 3 can be retracted into the protective sleeve 1 after sampling, preventing the sampling tube 3 from being damaged during the lifting process of the sampling device. When the sampling tube 3 needs to be extended for sampling, release the first pulling handle 53. Under the action of the counterweight 51, the driving rod 5 moves downward, and the driving frame 54 on the driving rod 5 can drive one end of the L-shaped rotating plate 22 to rotate downward, so that the sampling installation component 2 can extend out of the protective sleeve 1.

[0031] The upper end of the protective sleeve 1 is fixedly connected with a second pull rope 12, and the upper end of the second pull rope 12 is fixedly connected with a second pulling handle 13. During the sampling process, by pulling the second pulling handle 13 on the second pull rope 12, the entire sampling device can be placed in the groundwater for sampling. When the sampling device descends into the groundwater or is taken out from the groundwater, by pulling the first pulling handle 53 at the upper end of the first pull rope 52 upward, the sampling tube 3 can be retracted into the protective sleeve 1, and the position of the entire sampling device can be moved. To prevent the first pulling handle 53 or the second pulling handle 13 from falling during use, resulting in the inability to pull the first pulling handle 53 or the second pulling handle 13 again during use, connecting ropes of a certain length are provided on the first pulling handle 53 and the second pulling handle 13 to prevent the first pulling handle 53 or the second pulling handle 13 from falling into the underground space while not affecting the up and down movement of the first pulling handle 53 and the second pulling handle 13.

[0032] Please refer to Figures 4 - 6 , the sealing assembly 7 includes a telescopic airbag 71, an air duct 72 and a spherical airbag 75. The telescopic airbag 71 is fixedly installed on the lower surface of the upper end of the Z-shaped mounting plate 21, and the spherical airbag 75 is fixedly installed in the end inlet of the sampling tube 3. The upper side wall of the telescopic airbag 71 is connected with an air duct 72, and the end of the air duct 72 is fixedly connected to the air inlet of the spherical airbag 75. After the sampling is completed, since the L-shaped rotating plate 22 rotates upward, the telescopic airbag 71 can be squeezed during the rotation of the L-shaped rotating plate 22, so that the gas in the telescopic airbag 71 is conveyed into the spherical airbag 75 through the air duct 72. The spherical airbag 75 gradually expands, and then the port of the sampling tube 3 can be filled, so that the sampling tube 3 can be automatically sealed after the sampling is completed, preventing the sample in the sampling tube 3 from being contaminated.

[0033] And the lower end of the telescopic airbag 71 is fixedly connected with a movable flat plate 74. One end of the movable flat plate 74 is provided with a limiting rod 73 in a penetrating manner. The upper end of the limiting rod 73 is fixedly connected to the lower surface of the upper end of the Z-shaped mounting plate 21, which can prevent the telescopic airbag 71 from tilting to one side when the L-shaped rotating plate 22 squeezes the telescopic airbag 71, and avoid the situation that the gas inside it cannot be discharged into the spherical airbag 75 through the air duct 72 due to the tilt of the telescopic airbag 71.

[0034] Please refer to Figures 6 - 7, the automatic opening assembly 4 includes a fixed frame 41, guide rods 42, springs 43, a moving plate 44, push rods 45 and a strip-shaped rubber band 46. The fixed frame 41 is fixedly installed on the upper side of the end of the sampling tube 3. Guide rods 42 are symmetrically installed on the lower side of the middle section of the fixed frame 41. A moving plate 44 is slidably sleeved on the guide rods 42. Springs 43 are sleeved on the guide rods 42 at positions above the moving plate 44. A push rod 45 is connected to the lower side surface of the moving plate 44. The end of the push rod 45 is connected with a rubber sleeve. The strip-shaped rubber band 46 is fixedly installed inside the end of the sampling tube 3, and the strip-shaped rubber band 46 is perpendicular to the push rod 45. When sampling is to be carried out, when the L-shaped rotating plate 22 drives the sampling tube 3 to extend out of the protective sleeve 1, at this time, the telescopic airbag 71 is not squeezed by the L-shaped rotating plate 22. The gas in the spherical airbag 75 is conveyed into the telescopic airbag 71 under the action of the automatic opening assembly 4. Specifically, the moving plate 44 moves towards the sampling tube 3 under the action of the spring 43, and the push rod 45 can push the strip-shaped rubber band 46 to squeeze the spherical airbag 75, so that the spherical airbag 75 shrinks to one side of the port of the sampling tube 3. At this time, the port of the sampling tube 3 can be exposed, and the aqueous solution can enter the sampling tube 3. The strip-shaped rubber band 46 can protect the spherical airbag 75 when the push rod 45 pushes the spherical airbag 75, preventing the push rod 45 from puncturing the spherical airbag 75. And by setting the strip-shaped rubber band 46, the contact points between the push rod 45 and the spherical airbag 75 can be increased, and it is more convenient to squeeze the spherical airbag 75 to one side of the port of the sampling tube 3.

[0035] When this embodiment is in use, the sampling driving assembly can simultaneously control the sampling installation assembly 2, the sealing assembly 7 and the automatic opening assembly 4, so as to conveniently store and extend the sampling tube 3 during the sampling process, and can automatically open and close the port of the sampling tube 3 before and after sampling. The operation is simple and convenient, greatly reducing the complexity of the operation during sampling.

[0036] In order to more intuitively observe the specific situation of the underground water quality during the sampling process, existing sampling equipment usually installs a camera 61 on the sampling equipment to take pictures of the environment at the sampling point. In order to prevent the camera 61 from being damaged by immersion when used underwater, a protective cover 6 is usually arranged outside the camera 61 to ensure the normal use of the camera 61. However, the use of the camera 61 will generate a certain amount of heat, increasing the temperature inside the protective cover 6. After the sampling equipment enters the groundwater, due to the low temperature of the groundwater, fog will be generated on the inner wall of the protective cover 6, affecting the normal shooting of the camera 61. For this reason, the inventor has solved the above technical problems through long-term practical research.

[0037] Please refer to Figure 2 、 Figure 8 and Figure 9, a protective cover 6 is fixedly installed on the lower surface of the counterweight 51. A camera 61 is fixedly installed inside the protective cover 6. A circular notch for the protective cover 6 to enter and exit is opened at the lower bottom of the protective sleeve 1. An anti-fogging component 8 is installed on the protective cover 6. The anti-fogging component 8 includes a rack 81, a rotating gear 82 and an erasing roller 83. There are two racks 81 and two rotating gears 82. The two rotating gears 82 are symmetrically and rotatably installed on the protective cover 6 from left to right. The two racks 81 are symmetrically and vertically installed at the bottom of the protective sleeve 1 from left to right. The rotating gear 82 is meshed with the corresponding rack 81. An erasing roller 83 is rotatably installed inside the protective cover 6. The two ends of the erasing roller 83 are coaxially connected to the corresponding rotating gears 82 respectively. When the sampling device reaches the sampling point, the sampling driving component moves downward to drive the protective cover 6 and the camera 61 to move downward, so that the lower end of the protective cover 6 and the imaging end of the camera 61 extend out of the protective sleeve 1. The camera 61 can then take pictures of the environment around the sampling point. During the downward movement of the protective cover 6, since the rotating gears 82 installed on both sides of the protective cover 6 are meshed with the racks 81, the rotating gears 82 will rotate during the downward movement of the protective cover 6, so that the erasing roller 83 inside the protective cover 6 can rotate. During the rotation of the erasing roller 83, the fog on the inner wall of the protective cover 6 corresponding to the lens of the camera 61 can be wiped off. Moreover, the moving distance of the protective cover 6 can make the erasing roller 83 rotate exactly 180 degrees, so as to ensure that the erasing roller 83 will not block the shooting of the camera 61 after rotation. After sampling is completed, the protective cover 6 can automatically retract into the protective sleeve 1 following the retraction of the sampling pipe 3, preventing the protective cover 6 from contacting the stones in the underground space when the sampling device is taken out, resulting in damage to the protective cover 6.

[0038] Specifically, the erasing roller 83 is in a semi-circular ring shape. An erasing sponge is sleeved outside the erasing roller 83, which can wipe and absorb the fog on the inner wall of the protective cover 6. Moreover, the protective cover 6 is a detachable waterproof cover body. After sampling is completed and the sampling device is taken out of the water body, the protective cover 6 can be disassembled to facilitate dehumidifying the erasing roller 83 inside the protective cover 6 and performing maintenance and inspection on the camera 61.

[0039] In this embodiment, by setting the camera 61, the environment of the sampling point can be photographed to more accurately monitor the water quality of the underground space. By setting the anti-fogging component 8, the inner wall of the protective cover 6 can be defogged, so that the camera 61 can clearly photograph the environment of the sampling point. Moreover, the defogging of the protective cover 6, the deployment of the sampling pipe 3 and the opening of the sampling pipe 3 are carried out simultaneously, making the operation more convenient.

[0040] Specifically, the working principle of the underground space water quality monitoring and sampling device: When in use, first pull the first pulling handle 53 at the upper end of the first pulling rope 52. At this time, under the automatic action of the protective sleeve 1 and the sampling installation assembly 2, the sampling pipe 3 is inside the protective sleeve 1. Then gradually send the first pulling rope 52 into the underground space to send the entire sampling device to the sampling point. After the sampling device reaches the sampling point, pull the second pulling handle 13 and release the first pulling handle 53. At this time, under the action of the counterweight 51, the driving rod 5 moves downward, and the driving frame 54 on the driving rod 5 can drive one end of the L-shaped rotating plate 22 to rotate downward, so that the sampling installation assembly 2 can extend out of the protective sleeve 1. At the same time, the telescopic airbag 71 is not squeezed by the L-shaped rotating plate 22, and the moving plate 44 moves toward the sampling pipe 3 under the action of the spring 43. The push rod 45 can then push the strip-shaped rubber band 46 to squeeze the spherical airbag 75. The gas in the spherical airbag 75 is sent into the telescopic airbag 71 under the action of the automatic opening assembly 4, so that the spherical airbag 75 shrinks to one side of the port of the sampling pipe 3. At this time, the port of the sampling pipe 3 can be exposed, and the aqueous solution can enter the sampling pipe 3 to complete the water quality sampling.

[0041] And at this time, the lower end of the protective cover 6 and the imaging end of the camera 61 extend out of the protective sleeve 1, and the camera 61 can take pictures of the environment around the sampling point. During the downward movement of the protective cover 6, since the rotating gears 82 installed on both sides of the protective cover 6 are meshed with the rack 81, the rotating gears 82 will rotate during the downward movement of the protective cover 6, so that the erasing roller 83 inside the protective cover 6 can rotate. During the rotation of the erasing roller 83, the mist on the inner wall of the lower end of the protective cover 6 corresponding to the lens of the camera 61 can be wiped off.

[0042] After sampling is completed, pull the first pulling handle 53 at the upper end of the first pulling rope 52 upward. During the upward movement of the driving rod 5, the driving frame 54 provided on the side wall of the driving rod 5 can drive one end of the L-shaped rotating plate 22 to rotate upward, so that the sampling installation assembly 2 can rotate into the protective sleeve 1, so that the sampling pipe 3 can be received into the protective sleeve 1 after sampling is completed, preventing the sampling pipe 3 from being damaged during the lifting and lowering of the sampling device. During the rotation of the sampling installation assembly 2, the telescopic airbag 71 is squeezed, so that the gas in the telescopic airbag 71 is sent into the spherical airbag 75 through the air guide pipe 72. The spherical airbag 75 gradually expands and can fill the port of the sampling pipe 3, so that the sampling pipe 3 can be automatically sealed after sampling is completed, preventing the sample in the sampling pipe 3 from being contaminated. At the same time, the protective cover 6 can be received into the protective sleeve 1 to prevent the protective cover 6 from contacting the stones in the underground space and being damaged when the sampling device is taken out.

[0043] It should be noted that the specific model specifications of the camera 61, the telescopic airbag 71, and the spherical airbag 75 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0044] The power supply and its principle of the camera 61, the telescopic airbag 71, and the spherical airbag 75 are clear to those skilled in the art and will not be described in detail here.

[0045] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
