Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, and particularly relates to a sampling device and method for geothermal energy exploration. Background Art

[0002] As is well known, geothermal energy is a renewable energy source, mainly derived from the decay of radioactive substances inside the earth and the heat energy inside the earth. The existence of geothermal energy can cause the temperature of groundwater to rise. These groundwater may flow into rivers, thereby increasing the water temperature of certain sections of the rivers. This phenomenon is particularly obvious in areas with frequent geothermal activities. A sampling device and method for geothermal energy exploration is an auxiliary device that autonomously cruises in water bodies and real-time detects water quality parameters.

[0003] After retrieval, the patent with the Chinese patent publication number CN116754525A discloses an on-line water quality detection device and a control method for water quality detection. It is generally described as including a housing. An inwardly recessed receiving opening is formed on the side wall of the housing for receiving the water body to be tested. A first preset space and a second preset space are formed inside the housing. A first through hole and a second through hole are correspondingly provided on both sides of the housing and located at both sides of the receiving opening. The first preset space and the second preset space are respectively located on both sides of the receiving opening. The first through hole communicates with the first preset space, and the second through hole communicates with the second preset space. A first lens is disposed in the first through hole and forms a sealed connection with the first through hole. A second lens is disposed in the second through hole and forms a sealed connection with the second through hole. An optical cleaning device is correspondingly disposed with the first lens and the second lens. The cleaning device is used to clean the first lens and the second lens. When in use, it can improve the accuracy of water quality detection and can extend its service life. The patent with the Chinese patent publication number CN114544904A discloses a cruising water quality detection device and a detection method. It is generally described as including a first cylinder, a detection mechanism, and a drainage driving mechanism. The detection mechanism is inserted into the first cylinder. The drainage driving mechanism is installed at the end of the first cylinder. The detection mechanism includes a connecting plate and a second cylinder coaxially fixed. A control module and several detection units are electrically connected to the second cylinder. The detection probes of the detection units extend into the second cylinder. A submersible pump is installed on the connecting plate. The drainage driving mechanism includes a mounting seat fixed to the end of the first cylinder, a C-shaped frame rotatably connected in the middle to the mounting seat, and a driving component for driving the C-shaped frame to rotate around the axial direction of the first cylinder. A nozzle mechanism is provided inside the C-shaped frame. A water flow velocity measuring device is provided outside the first cylinder. The water flow velocity measuring device, the submersible pump, the driving component, and the first solenoid valve are all electrically connected to the control module. When in use, it can ensure water quality sampling and can realize cruising in water to facilitate the detection of large-area water quality.

[0004] Although the above two prior art solutions can both achieve water quality detection, it is difficult to achieve multi-point detection of large-area water quality with the former water quality detection method. Moreover, the detection method is based on the optical approach. Although it can be repeated, the limitations of the detection items are relatively large. At the same time, the autonomous mobility during the detection process is relatively low. For the latter, although it can cruise in water and achieve the detection of large-area water quality, the introduction of the detection unit formed after water quality extraction is too general. And it can be found from the full text of the research that the detection unit is single, and the water sample detection at different detection points is all achieved through this single detection unit. Therefore, its application limitations are relatively large, and if residues are formed in the detection unit, it will also affect the accuracy of subsequent detection data. Summary of the Invention

[0015] A detection method for a sampling device for geothermal energy exploration includes the following steps: S1. Before use, first install a storage battery, a control host and a wireless communication module for the floating body on the water, and complete the electrical installation between the control host, the wireless communication module, the detection probe group, the spherical camera, the driving structure, the propeller and the folding adjustment frame and the storage battery. At the same time, complete the electrical connection between the wireless communication module, the detection probe group, the spherical camera, the driving structure, the propeller and the folding adjustment frame and the control host to facilitate power supply and signal transmission, and perform relevant debugging; S2. When in use, place the whole sampling device for geothermal energy exploration on the water surface. During operation, the propeller works electrically to assist in driving the floating body on the water relative to the water surface, forming a movement adjustment according to the position to be detected, and through the unfolding operation of the folding adjustment frame, realizing the pushing adjustment of the underwater spindle-shaped frame relative to the floating body on the water, so as to realize the extension of the underwater spindle-shaped frame relative to the detected water body and achieve the water quality detection at different depths underwater; S3. During the detection process, when the water quality is not sampled and detected, the detection bottles do not rotate into the underwater spindle-shaped frame. At this time, the detection probe group detects the free water samples entering the underwater spindle-shaped frame, and realizes the detection of the water samples at multiple detection points along with the movement of the underwater spindle-shaped frame; S4. During the detection process, when the water quality is sampled and detected, the driving structure works to drive the movement of the chain belt, and then drives the movement of the plurality of detection bottles, so that the detection bottles enter the underwater spindle-shaped frame. Under the cooperation of the auxiliary filling structure, the bottle cap is opened relative to the detection bottle, so that the inside of the detection bottle is communicated with the water in the water sample detection area, so as to realize the entry of the water sample into the detection bottle, and the water entering the detection bottle will be further detected through the detection test strip group; After the water sample enters the corresponding detection bottle, the driving structure works again to realize the rotation of the detection bottle relative to the underwater spindle frame. After the detection bottle rotates relative to the underwater spindle frame, the driving effect of the auxiliary filling structure on the bottle cap fails, and the bottle cap forms a seal relative to the detection bottle, thereby forming a storage of the water sample that has flowed into the detection bottle. S6. Along with the movement of the underwater spindle frame, after the water quality of multiple water sample detection points is detected, the water sample in the detection bottle that has completed sampling will fully interact with the test paper group to form corresponding detections. And when the detection bottle rotates into the annular storage bin again, the corresponding data of the test paper group can be captured by the spherical camera. The water quality data collected by the detection probe group and the detection data collected by the spherical camera are first sorted and guided by the control host, and then transmitted outward through the wireless communication module.

[0016] Compared with the prior art, the present invention provides a sampling device and method for geothermal energy exploration, which has the following beneficial effects: (1) In the present invention, through the design of the detection mechanism, a detection mechanism that can be submerged relative to the water surface is formed. The detection items are more abundant, and each detection point adopts a relatively independent detection form. The mutual influence between multiple detection points is small, the detection data is more reliable, and the detection repeatability is better.

[0017] (2) In the present invention, through the design of the floating carrier mechanism, a storage-type carrier is formed in combination with the detection mechanism. While storing the detection mechanism, a basic cruising water quality detection operation is realized. The detection position is wider, and due to the form of floating on the water, the limitation of structure and size is small, and the practicability is better.

[0018] (3) In the present invention, through the design of the folding adjustment frame, the relative connection and installation between the detection mechanism and the floating carrier mechanism are realized, which is convenient for adjusting the relative position of the detection mechanism relative to the floating carrier mechanism to realize the delivery and recovery of the detection mechanism relative to the water sample area. And the folding rate is high. Under the same storage space occupation, the unfolded length is larger, and the relative delivery area of the detection mechanism is deeper.

Multiple connecting springs 26 are respectively fixedly connected to multiple fixed seats 24. Elastic clamping openings 27 are arranged within multiple slide frames 25, and multiple detection bottles 4 are respectively detachably installed within multiple elastic clamping openings 27. The fixed seats 24 and the slide frames 25 are both made of transparent materials, forming the specific installation structure of the detection bottles 4. The transparent materials also provide basic visual conditions for the subsequent spherical camera 8. Detection paper strip groups 5 are arranged within multiple detection bottles 4, and synchronous frames 47 are arranged within multiple detection bottles 4.

The permanent magnet 31 matches the multiple iron bars 32, and the biasing push frame 30 matches the multiple slide frames 25. After the detection bottle 4 moves to the corresponding position within the underwater spindle-shaped frame 1, with the mutual cooperation of the permanent magnet 31 and the iron bars 32 within the bottle caps 6 of the detection bottles 4 that enter the underwater spindle-shaped frame 1, when the detection bottle 4 is pushed by the biasing push frame 30, relative sliding of the bottle cap 6 with respect to the cover frame 28 can be achieved, and then the opening of the bottle cap 6 with respect to the detection bottle 4 can be realized. A detection probe group 7 is installed within the underwater spindle-shaped frame 1, and a spherical camera 8 is installed on the underwater spindle-shaped frame 1. The annular storage bin 2 and multiple detection bottles 4 are both made of transparent materials, and a take-and-place strip opening is arranged on the outer ring surface of the annular storage bin 2.An L-shaped strip cover 9 is detachably installed in the pick-and-place strip opening, and a contact seal is provided between the L-shaped strip cover 9 and the pick-and-place strip opening. Through the design of the detection mechanism, a detection mechanism that can be submerged relative to the water surface is formed.

The detection position is wider. Since the water surface suspension form is adopted, the limitation of the structure and size is small, and the practicability is better.

[0024] It should be further noted that the underwater spindle frame 1 is installed in the middle installation port through two folding adjustment frames. The folding adjustment frame includes a fixed installation cylinder 12, an adjustment installation cylinder 13, a head folding frame 14, a tail folding frame 15 and a plurality of middle folding frames 16.

The plurality of return spring cones 23 are respectively fixedly connected to the plurality of sliding shafts 17. Through the design of the folding adjustment frame, the relative connection and installation between the detection mechanism and the floating carrier mechanism are realized, which facilitates the adjustment of the relative position of the detection mechanism relative to the floating carrier mechanism, so as to realize the delivery and recovery of the detection mechanism relative to the water sample area. Moreover, the folding rate is relatively high. Under the same storage space occupation, the unfolded length is greater, and the relative deployable area of the detection mechanism is deeper.

[0025] The storage battery, the control host, the wireless communication module, the electromagnet 21, the electromagnet 38, the detection probe group 7, the spherical camera 8 and the propeller 11 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them without improving their structures and functions. For those skilled in the art, their setting methods, installation methods and electrical connection methods can be debugged and operated as required in their user manuals, and will not be elaborated here.

[0026] In summary, the working principle of the sampling device and method for geothermal energy exploration is as follows. Before use, first install a battery, a control host, and a wireless communication module inside the floating body 10 on the water, and complete the electrical installation between the control host, the wireless communication module, the detection probe group 7, the spherical camera 8, the electromagnet 21, the electromagnet 38, and the propeller 11 and the battery. At the same time, complete the electrical connection between the wireless communication module, the detection probe group 7, the spherical camera 8, the electromagnet 21, the electromagnet 38, and the propeller 11 and the control host to facilitate power supply and signal transmission, and conduct relevant debugging. Through the control host, the respective operations of the wireless communication module, the detection probe group 7, the spherical camera 8, the electromagnet 21, the electromagnet 38, and the propeller 11 can be realized. Through the wireless communication module, the information interaction between the control host and the outside world can be realized. When in use, place the whole sampling device for geothermal energy exploration on the water surface. During operation, the propeller 11 is powered on to work to assist in realizing the movement drive of the floating body 10 on the water relative to the water surface, and the movement adjustment is formed according to the position to be detected. Under the actual operation state, if the water surface has fluidity, the movement of the floating body 10 on the water can also be realized by means of the flow of the water surface. To facilitate determining the relative position of the floating body 10 on the water, a Beidou navigation system is installed inside the floating body 10, and according to the usage requirements, a solar panel can be installed on the floating body 10 to improve the battery life of the battery. Through the unfolding operation of the folding adjustment frame, that is, multiple electromagnets 21 are powered on to generate an electromagnetic field acting on the permanent magnet rod 22, so that the circular shaft section 18 on the sliding shaft 17 changes its position relative to the shaft hole. Under the relative action of the spiral groove 20 and the spiral plate 19, the rotational unfolding between the fixed installation cylinder 12 and the first folding frame 14 can be realized, the rotational unfolding between the first folding frame 14 and a middle folding frame 16 away from it can be realized, the mutual rotational unfolding between two adjacent middle folding frames 16 can be realized, the rotational unfolding between the tail folding frame 15 and a middle folding frame 16 away from it can be realized, and the rotational unfolding between the tail folding frame 15 and the adjustment installation cylinder 13 can be realized, so as to realize the pushing adjustment of the underwater fusiform frame 1 relative to the floating body 10 on the water, so as to realize the extension of the underwater fusiform frame 1 into the detection water body. By controlling the current magnitude of the electromagnet 21, the water quality detection at different depths underwater can be achieved. During the detection process, when the water quality is not sampled and detected, the detection bottle 4 does not rotate into the underwater fusiform frame 1. At this time, the detection probe group 7 detects the free water samples entering the underwater fusiform frame 1, and the detection of the detection water samples at multiple detection points is realized along with the movement of the underwater fusiform frame 1. During the detection process, when the water quality is sampled and detected, the driving structure works to drive the movement of the belt chain 3, and then the movement of multiple detection bottles 4 is driven, so that the detection bottles 4 enter the underwater fusiform frame 1. The working process of the driving structure is that the electromagnetic field generated by the electromagnet 38 being powered on acts on the iron column 39, so that the driving column 36 overcomes the return spring 37 and moves relative to the external installation frame 33. Under the relative action of the side track groove 41 and the transmission rod 43, the rotation drive of the driving wheel 34 is realized.The rotation of the driving wheel 34 acts on the multiple fixed seats 24 in sequence through a plurality of driving notches 35 to achieve the sequential driving of the multiple fixed seats 24. The locally driven fixed seats 24 drive the movement of the belt chain 3, thereby forming the synchronous driving of the multiple detection bottles 4.

[0027] Further, during the movement of the transmission rod 43 relative to the side track groove 41, since there are height differences at both communication points between the spiral section 45 and the straight section 46, the one-way direction during the mutual switching between the spiral section 45 and the straight section 46 can be ensured. And to ensure the realization of not sampling and detecting the water quality and sampling and detecting the water quality, there is a vacant position between two adjacent detection bottles 4. That is, the electromagnet 38 needs to be continuously powered on twice to drive two adjacent detection bottles 4 to complete the switching relative to the underwater spindle-shaped frame 1. When one detection bottle 4 is located inside the underwater spindle-shaped frame 1, when the electromagnet 38 is powered on once, the detection bottle 4 located inside the underwater spindle-shaped frame 1 will be moved out of the detection bottle 4, and the vacant position between the two detection bottles 4 will enter the underwater spindle-shaped frame 1. When the electromagnet 38 is powered on again, the vacant position between the two detection bottles 4 will be moved out of the underwater spindle-shaped frame 1, and the next detection bottle 4 will enter the underwater spindle-shaped frame 1. The detection bottle 4 that enters the underwater spindle-shaped frame 1, under the cooperative action of the auxiliary filling structure, achieves the opening of the bottle cap 6 relative to the detection bottle 4, so that the inside of the detection bottle 4 is in communication with the water in the water sample detection area, and then the water sample enters the detection bottle 4. The water that enters the detection bottle 4 will be further detected through the test paper group 5. The opening process of the bottle cap 6 is as follows: after the detection bottle 4 enters the underwater spindle-shaped frame 1, due to the magnetic attraction between the permanent magnet 31 and the iron bar 32, when the biasing frame 30 pushes the sliding frame 25, the sliding frame 25 moves away from the fixed seat 24 against the elastic action of the connecting spring 26. At the same time, the detection bottle 4 inside the sliding frame 25 will also move away from the fixed seat 24, so as to achieve the separation of the cap frame 28 from the permanent magnet 31, and then realize the relative sliding opening of the bottle cap 6 relative to the cap frame 28. After the water sample enters the corresponding detection bottle 4, the driving structure works again to realize the rotation of the detection bottle 4 relative to the underwater spindle-shaped frame 1. And after the detection bottle 4 rotates out of the underwater spindle-shaped frame 1, the driving effect of the auxiliary filling structure on the bottle cap 6 fails, and the bottle cap 6 is closed relative to the detection bottle 4, thereby forming the storage of the water sample that has flowed into the detection bottle 4. Along with the movement of the underwater spindle-shaped frame 1, after the water quality of multiple water sample detection points is detected, the water sample in the detection bottle 4 that has completed sampling will fully interact with the test paper group 5 to form corresponding detections. And when the detection bottle 4 rotates into the annular storage bin 2 again, the corresponding data of the test paper group 5 can be captured by the spherical camera 8. The water quality data collected by the detection probe group 7 and the detection data collected by the spherical camera 8 are first sorted and collected by the control host, and then transmitted outward through the wireless communication module.

[0028] Furthermore, for the selection of the test paper group 5, a variety of test papers can be selected, such as pH test paper for detecting the acidity and alkalinity of the water body, ammonia nitrogen test paper for detecting the ammonia nitrogen content in the water body, and heavy metal test paper for detecting the heavy metal content in the water body. Since the test paper is detected and identified by color change, the spherical camera 8 can make judgments based on image acquisition, and considering the influence of impurities and light transmittance of the water body, when the spherical camera 8 is unable to well acquire the image of the test paper in the water body, it is possible to wait until the underwater shuttle frame 1 enters a suitable water quality environment or the underwater shuttle frame 1 is recovered into the floating body 10 before collecting image data. Since geothermal activity may not only increase the water temperature of certain sections of the river but also cause changes in the chemical composition of the water, these changes may include an increase in mineral content or the dissolution of other chemical substances. Therefore, the detection probe group 7 should include a temperature sensor and a variety of optical detection probes, such as an optical turbidity probe and an optical chlorophyll probe. Since the water quality is sampled and tested Water samples are collected during the test, so the water samples can be subsequently tested while being tested by the test paper group 5, which enriches the detection scope. In order to facilitate the distinction of water samples, the test bottle 4 should be designed with a label, and multiple sliding racks 25 are also equipped with serial numbers. Through the corresponding records of the labels and serial numbers, the correspondence between different test bottles 4 and different locations is realized. After the sampling is completed, the test bottle 4 can be disassembled relative to the sliding rack 25, which is not only convenient for the subsequent treatment of the water sample after use, but also convenient for the placement and installation of new test bottles 4, further expanding the number of test samples extracted and the practicality of the sampling device for geothermal energy exploration. Based on the detection data of the temperature sensor and various optical detection probes contained in the sampling device for local thermal energy exploration, the water samples in the test bottle 4 corresponding to the area with abnormally increased temperature and abnormally increased mineral content or chemical substance content are preferentially detected to determine the possibility of geothermal energy in the area, thereby achieving the purpose of geothermal energy exploration, so as to form a general regional exploration of geothermal energy and provide preparation for the subsequent accurate determination of the location of geothermal energy.
