Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a limestone geothermal well water sampling device. Background Art

[0002] Limestone geothermal wells are energy facilities that utilize hot water resources in underground limestone formations. The water in these geothermal wells contains rich geothermal energy and minerals, which is of great value for studying geological structures, developing clean energy, and conducting related scientific research. The main purpose of the sampling device is to safely and accurately collect well water samples from limestone geothermal wells in order to analyze and detect the physical properties, chemical composition, and microbial content of the well water. By conducting in-depth research on the well water obtained by sampling, we can better understand the distribution and characteristics of geothermal resources, provide a scientific basis for the rational development and utilization of geothermal resources, and also help monitor the operating status and environmental impact of geothermal wells.

[0003] Traditional limestone geothermal well water sampling devices usually consist of sampling containers, connecting pipes, valves and lifting devices. The sampling containers are generally metal or plastic containers used to store the collected well water samples. The connecting pipes connect the sampling containers to the wellhead of the geothermal well and are usually made of pressure-resistant and corrosion-resistant materials. The valves are used to control the inflow and outflow of well water so that samples can be collected at the right time. The lifting device is used to lower the sampling container into the geothermal well and lift it to the ground after sampling is completed. In some traditional devices, some simple filtering devices are also equipped to prevent impurities from entering the sampling container.

[0004] The sampling head of the traditional limestone geothermal well water sampling device is directly connected to the connecting pipe without a rotating mechanism. This structural design is mainly to reduce the complexity and cost of the device, but it also brings some obvious disadvantages. The sampling head that cannot rotate cannot achieve multi-angle sampling. The well water in the geothermal well is stratified, and the composition of the well water at different depths and locations will be different. If the sampling head cannot rotate, it can only be sampled at a fixed angle, and it is impossible to fully understand the well water conditions at different locations in the well, which affects the representativeness and accuracy of the sampling. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a limestone geothermal well water sampling device, which aims to improve the problem that the sampling head of the traditional limestone geothermal well water sampling device cannot fully understand the well water conditions at different positions in the well, thereby affecting the representativeness and accuracy of the sampling.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a limestone geothermal well water sampling device, comprising a frame, a hanging platform slidably connected to the interior of the frame, a plurality of side platforms fixedly connected to the side walls of the hanging platform, a fixed platform provided on the top of the frame, an adjustment component provided on the bottom of the side platform, the adjustment component being used for diversified sampling, a fixing component provided on the top of the frame, and the fixing component being used for cleaning and maintaining the fixed platform;

[0007] The adjustment assembly includes a fixed frame, and multiple fixed frames are fixedly connected to the lower surface of the side platform, wherein two adjacent side walls of the fixed frames are fixedly connected to motors, and each output end of the motor is fixedly connected to a connecting frame, a slide groove is provided inside the connecting frame, and a connecting platform is fixedly connected to the lower surface of the hanging platform, and a sliding column is slidably connected inside the connecting platform, and a sampling head is provided at the bottom of the sliding column, and the sliding column is slidably connected inside the multiple slide grooves.

[0008] Furthermore, the fixing assembly includes a fixing platform, and the fixing platform is fixedly connected to the inside of the vehicle frame.

[0009] Furthermore, an electric motor is fixedly connected to the top of the fixed platform, and a transmission column is fixedly connected to the output end of the electric motor.

[0010] Furthermore, a plurality of fixed rails are fixedly connected to the upper surface of the fixed platform, and the fixed rails are bilaterally symmetrical with respect to the fixed platform.

[0011] Furthermore, a fixed plate is slidably connected to the top of each fixed rail, and a transmission plate is fixedly connected to the top of the transmission column.

[0012] Furthermore, a clamping platform is fixedly connected to the top of each fixed plate, and a plurality of connecting shafts are rotatably connected inside the transmission plate.

[0013] Furthermore, each outer wall of the connecting shaft is rotatably connected to a connecting rod, and the side wall of the fixing plate is fixedly connected to a connecting piece.

[0014] Furthermore, one end of the connecting rod is rotatably connected to the bottom of the connecting piece, and the plurality of clamping platforms are slidably connected to the outer wall of the sampling tank.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present invention, the motor first outputs a rotational force to the connecting frame to drive the connecting frame to rotate on the side wall of the fixed frame, and finally drives the sliding column to slide inside the slide groove, thereby changing the horizontal axis angle. At the same time, another motor drives the rotation of another connecting frame to achieve the change of the vertical axis angle. The sampling angle of the sampling head is changed to sample at different angles, thereby obtaining water samples at different positions in the well more comprehensively, making the samples more representative and able to more accurately reflect the overall situation of the geothermal well water.

[0017] 2. In this utility model, an electric motor applies a rotational force to the transmission column, which in turn drives the fixed plate to slide on top of the fixed rail. The relative sliding of multiple fixed plates changes the relative distance between multiple clamping platforms, enabling rapid assembly and disassembly of sampling canisters, allowing containers to be quickly separated from the device without complex disassembly procedures. This significantly reduces pre-cleaning preparation time, allowing cleaning work to begin as soon as possible and improving overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 2The utility model provides an embodiment of a limestone geothermal well water sampling device, comprising a frame 1, the frame 1 provides support and movement functions, the frame 1 is internally slidably connected to a hanging platform 2, the hanging platform 2 can be lowered to the bottom of the well, the side walls of the hanging platform 2 are fixedly connected to a plurality of side platforms 3, a fixed platform 12 is provided on the top of the frame 1, an adjustment component is provided at the bottom of the side platform 3, the adjustment component is used for diversified sampling, a fixed component is provided on the top of the frame 1, the fixed component is used for cleaning and maintaining the fixed platform 12;

[0025] The adjustment component includes a fixed frame 4, which is used to support and drive. Multiple fixed frames 4 are fixedly connected to the lower surface of the side platform 3, wherein two adjacent side walls of the fixed frames 4 are fixedly connected to motors 5, and each output end of the motor 5 is fixedly connected to a connecting frame 6. The angles of the multiple connecting frames 6 respectively determine the angles of the horizontal and vertical axes of the sampling head 10. A slide groove 7 is provided inside the connecting frame 6, and the slide groove 7 can push and pull the slide column 9 when the connecting frame 6 rotates. A connecting platform 8 is fixedly connected to the lower surface of the hanging platform 2, and a slide column 9 is slidably connected inside the connecting platform 8. The angle of the slide column 9 drives the angle of the sampling head 10 at its bottom to change. A sampling head 10 is provided at the bottom of the slide column 9, and the slide column 9 is slidably connected inside multiple slide grooves 7.

[0026] Specifically, first, when it is necessary to sample and collect well water at different angles, the motor 5 can be started. The motor 5 will first output rotational force to the connecting frame 6, driving the connecting frame 6 to rotate on the side wall of the fixed frame 4. During the rotation of the connecting frame 6, the slide groove 7 opened inside it will apply thrust to the slide column 9, driving the slide column 9 to slide inside the slide groove 7, thereby changing the angle of the horizontal axis. At the same time, another motor 5 drives another connecting frame 6 to rotate, so as to achieve the change of the vertical axis angle. In this way, the collection angle of the sampling head 10 changes, and sampling can be performed at different angles, so that water samples at different positions in the well can be obtained more comprehensively, making the samples taken more representative, and to a certain extent, being able to more accurately reflect the overall situation of the geothermal well water.

[0027] Reference Figure 3The fixed assembly includes a fixed platform 12, which is fixedly connected to the inside of the frame 1, and an electric motor 13 is fixedly connected to the top of the fixed platform 12. The output end of the electric motor 13 is fixedly connected to a transmission column 14, and the transmission column 14 transmits the driving force to the top structure. A plurality of fixed rails 16 are fixedly connected to the upper surface of the fixed platform 12. The fixed rails 16 ensure that the sliding of the top fixed plate 17 remains horizontal. The fixed rails 16 are symmetrical with respect to the fixed platform 12. The top of each fixed rail 16 is slidably connected to a fixed plate 17, and the top of the transmission column 14 is fixedly connected to a transmission plate 15. The top of each fixed plate 17 is fixedly connected to a card table 21, and the card table 21 directly fixes the sampling tank 11. A plurality of connecting shafts 20 are rotatably connected to the inside of the transmission plate 15. The connecting shaft 20 is used for the rotation of the connecting rod 19. The outer wall of each connecting shaft 20 is rotatably connected to the connecting rod 19. The side wall of the fixed plate 17 is fixedly connected to a connecting piece 18. One end of the connecting rod 19 is rotatably connected to the bottom of the connecting piece 18, and a plurality of card tables 21 are slidably connected to the outer wall of the sampling tank 11.

[0028] Specifically, if the residual water sample and impurities after the last sampling are not removed in time, it will have a relatively obvious impact on the result of the next sampling. When the sampling tank 11 needs to be disassembled for maintenance and cleaning, the electric motor 13 can be started. The electric motor 13 will apply a rotational force to the transmission column 14, driving the transmission column 14 to rotate. The positions of the two ends of the transmission column 14 will then change, and the connection with the connecting shaft 20 will pull the connecting rods 19 on both sides. After being subjected to the force, the connecting rods 19 will first rotate and change their own inclination angles, further pulling the connecting piece 18 at one end thereof. The connecting piece 18 serves as the connecting part between the card table 21 and the fixed plate 17, driving the fixed plate 17 to slide on the top of the fixed rail 16. The relative sliding of multiple fixed plates 17 can change the relative distance between multiple card tables 21, thereby realizing rapid disassembly and assembly of the sampling tank 11, and the container can be quickly separated from the device without a complicated disassembly process. To a certain extent, the preparation time before cleaning is greatly saved, so that the cleaning work can start as soon as possible, thereby improving the overall work efficiency.

[0029] Working principle: First, when it is necessary to sample well water at different angles, start the motor 5. The motor 5 will first output a rotational force to the connecting frame 6 to drive the connecting frame 6 to rotate on the side wall of the fixed frame 4. During the rotation of the connecting frame 6, the chute 7 provided inside it can apply a thrust to the slide column 9, driving the slide column 9 to slide inside the chute 7, thereby changing the horizontal axis angle. At the same time, another motor 5 drives the rotation of another connecting frame 6 to achieve a change in the vertical axis angle. The change in the collection angle of the sampling head 10 can sample at different angles, thereby obtaining water samples at different positions in the well more comprehensively, making the samples more representative, and being able to more accurately reflect the overall situation of the geothermal well water. If the residual water sample and impurities after the last sampling are not removed in time, the next sampling will be affected. The sampling results are seriously affected. When the sampling tank 11 needs to be disassembled and maintained and cleaned, the electric motor 13 is started. The electric motor 13 will apply a rotational force to the transmission column 14 to drive the transmission column 14 to rotate. The positions of the two ends of the transmission column 14 can be changed, and the connection with the connecting shaft 20 pulls the connecting rods 19 on both sides. After being subjected to force, the connecting rods 19 first rotate and change their own inclination angles, and further pull the connecting piece 18 at one end. The connecting piece 18 serves as a connection between the card table 21 and the fixed plate 17, driving the fixed plate 17 to slide on the top of the fixed rail 16. The relative sliding of multiple fixed plates 17 can change the relative distance of multiple card tables 21, realizing rapid disassembly and assembly of the sampling tank 11, and the container can be quickly separated from the device without a complicated disassembly process. This can greatly save the preparation time before cleaning, enable the cleaning work to start as soon as possible, and improve the overall work efficiency.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
