Description

Technical Field

[0001] The invention relates to the technical field of exploration and measurement, and in particular to a water temperature gradient depth measurement device based on a seismic environment. Background Art

[0002] Seismic underground fluid observation wells generally have means of observing water level and deep water temperature. There are high requirements for the placement of water temperature sensors, which must meet the following requirements: 1. Intervals with large water temperature gradients; 2. Intervals with small water temperature background noise; 3. Intervals with obvious water temperature tidal effects. This requires us to accurately measure the water temperature gradient of the wells. Many fluid observation wells are oil or coal mining wells with depths ranging from hundreds to thousands of meters. Currently, the water temperature gradient can only be measured by manually operating a simple length measuring device, but the error is large. In order to accurately measure the water temperature at different depths and determine the placement position of the water temperature sensor, the device of the present invention is designed.

[0003] A deep well water temperature gradient measuring device for seismic observation is disclosed in a patent application with reference publication number CN216925847U. The deep well water temperature gradient measuring device for seismic observation utilizes a retractable drive mechanism to drive the sensor retractable mechanism to rotate, so as to realize the retraction and extension of the cable, thereby adjusting the height position of the temperature sensor. The depth of the temperature sensor entering the water is measured by the depth measuring mechanism, so as to calculate the depth of the temperature sensor entering the water, thereby combining the depth of the temperature sensor entering the water with the data measured by the temperature sensor to realize the gradient measurement of the water temperature.

[0004] At present, the water temperature gradient is measured manually or by a retracting and releasing mechanism. For example, the above-mentioned water temperature measuring device also uses a retracting and releasing mechanism in conjunction with a temperature sensor to complete the measurement work. However, the temperature sensor on the water temperature measuring device is currently exposed directly into the deep well. Therefore, the temperature sensor is easily damaged by contact with foreign objects during the retracting and releasing process. Moreover, the temperature sensor is easily exposed for a long time and a large amount of debris is easily accumulated, which affects the accurate measurement of the water temperature, and the water temperature gradient data cannot be collected in an orderly manner, which affects the subsequent data analysis results. At the same time, the current water temperature measurement device does not provide balance assistance for the retraction and extension of the temperature sensor. Therefore, the temperature sensor cannot maintain relative balance when measuring water temperature, which affects the orderly progress of the measurement work, increases the difficulty of water temperature measurement, and cannot complete accurate analysis of the water temperature in the earthquake environment, which is not conducive to subsequent data research.

[0023] Embodiment 1: The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a water temperature gradient depth measuring device based on a seismic environment includes an assembly frame 1, a winding roller 2 is rotatably arranged on the assembly frame 1 through a bearing, a cable 3 is wound on the winding roller 2, a forward and reverse numerical control motor 4 is installed on one side of the assembly frame 1 through a bracket, and the forward and reverse numerical control motor 4 is connected to the winding roller 2 through a chain. Specifically, a sprocket connected to the chain transmission is installed at one end of the winding roller 2 and the output end of the forward and reverse numerical control motor 4, a support leg is arranged at the bottom of the assembly frame 1, and slidable ground nails are arranged at the four corners of the assembly frame 1, which can be fixed to the ground, and a control cabinet is installed on one side of the top of the assembly frame 1, and also includes: The receiving mechanism is arranged on the assembly frame 1 to complete the retracting and releasing control operation of the cable 3. The receiving mechanism is divided into a sensing unit and two limiting units. The sensing unit is used to receive the retracting and releasing data of the cable 3. The two limiting units are used to complete the active guiding and limiting of the cable 3. A guiding mechanism is arranged in the detection area to complete the guiding control operation of the cable 3, and the guiding mechanism includes an adjusting frame 5, a movable pulley 6 is slidably arranged in the adjusting frame 5, a plurality of connecting holes are arranged side by side on the adjusting frame 5, and a connecting bolt is slidably penetrated on the movable pulley 6, and the connecting bolt passes through the connecting hole to restrict the movable pulley 6 on the adjusting frame 5; The detection mechanism is arranged at the bottom of the cable 3 for active measurement of water temperature. The detection mechanism is divided into an auxiliary unit, a shell, a detection unit, a dynamic cleaning unit and a control unit. The auxiliary unit is arranged at the top of the shell to complete the dynamic counterweight action, and the auxiliary unit is detachably fixedly connected to the cable 3. The detection unit is movably arranged in the shell for water temperature measurement. The dynamic cleaning unit is used to complete the auxiliary cleaning work of the detection unit. The control unit is arranged in the shell to complete the synchronous control of the detection unit, the auxiliary unit and the dynamic cleaning unit.

[0024] Among them, electrical components such as the forward and reverse CNC motor 4, the electric push rod 32, and the measuring sensor 31 are all connected to a switch through wires, and the switch is electrically connected to a controller. The specific structure of the controller is not limited. An absolute encoder is installed on the forward and reverse CNC motor 4 for accurately positioning the forward and reverse CNC motor 4.

[0025] Embodiment 2: Based on the receiving mechanism provided in Embodiment 1, this embodiment provides a further technical solution for the receiving mechanism.

[0026] like Figure 5 and Figure 6 As shown, the sensing unit includes: A rectangular frame 7 is arranged on the assembly frame 1, a rotating shaft 8 is rotatably mounted on the rectangular frame 7 through a bearing, a rotation sensor 9 is connected to the rotating shaft 8 on one side of the rectangular frame 7, and a torque sensor 10 is connected to the rotating shaft 8 on the other side of the rectangular frame 7; A fixed pulley 11 is fixedly sleeved outside the rotating shaft 8 to guide the cable 3; In the embodiment of the present invention, each limiting unit includes: A limiting frame 12 is provided on the rectangular frame 7; Two guide wheels 13 are symmetrically arranged at the top and bottom of the limiting frame 12 to actively guide the cable 3; It is worth noting that when the detection mechanism is retracted and released: by providing a receiving mechanism, the cable 3 passes through the guide wheels 13 of the two limiting units, so that the cable 3 can be stably limited and guided. At the same time, the cable 3 correspondingly bypasses the fixed pulley 11, and the fixed pulley 11 can guide the retracted cable 3, so that the cable 3 can be stably retracted and released. At the same time, during the rotation of the fixed pulley 11, the speed sensor 9 can accurately obtain the release length data of the cable 3, which is beneficial to control the lowering depth of the detection mechanism. The torque sensor 10 obtains the torque of the cable 3 during retraction and release, and can accurately judge the stability of the retraction and release of the detection mechanism. When the data detected by the torque sensor 10 deviates too much from the predetermined data, it means that the detection mechanism is blocked by an obstacle during the retraction and release process, and the forward and reverse CNC motor 4 is synchronously controlled to stop running, and the operator is warned to take the initiative to intervene, thereby improving the safety of retraction and release. At the same time, due to the design of the guiding mechanism, the movable pulley 6 can move within the adjustment frame 5, which is convenient for fine-tuning the retraction and release position of the detection mechanism, enriching the detection range, and facilitating free adjustment.

[0027] Embodiment 3: Based on the detection mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the detection mechanism.

[0028] like Figure 7 and Figure 8 As shown, the housing includes: A circular shell 14 is disposed at the bottom of the auxiliary unit. The circular shell 14 is made of metal. An adjustment area 15 is disposed in the middle of the circular shell 14. A plurality of through areas 16 communicating with the adjustment area 15 are disposed in a circular array around the circular shell 14. The isolation plate 17 is arranged at the bottom of the circular housing 14 through a bracket; The storage area 18 is disposed at the bottom of the circular housing 14 and communicates with the adjustment area 15; like Fig. 9 and Fig.10 As shown, in an embodiment of the present invention, the auxiliary unit includes: The counterweight 19 is arranged on the top of the circular housing 14. The top of the counterweight 19 is detachably fixedly connected to the cable 3. The counterweight 19 is made of metal or other materials to complete the counterweight setting, so that the detection mechanism can be smoothly retracted and released. The counterweight area 20 is provided in the counterweight member 19 and communicates with the outside. A piston plate 21 is provided in the counterweight area 20 in a sliding and sealing manner. A No. 1 pipe 22 is connected to one side of the bottom of the counterweight area 20, and a No. 1 one-way valve for controlling the one-way entry of the medium into the counterweight area 20 is installed at the end of the No. 1 pipe 22. A No. 2 pipe 23 is connected to the other side of the bottom of the counterweight area 20, and a No. 2 one-way valve for controlling the one-way exit of the medium from the counterweight area 20 is installed at the end of the No. 2 pipe 23. It is worth noting that when the detection unit is dynamically counterweighted: by providing an auxiliary unit, the weight of the counterweight 19 can be used to control the circular housing 14 and the measuring sensor 31 to move downward stably, thereby ensuring the stability of the retraction and release. At the same time, a counterweight area 20 is provided in the counterweight 19. Under normal circumstances, when the measuring sensor 31 is hidden in the storage area 18, the piston plate 21 is pushed upward in the counterweight area 20 via the operating rod 35, and the liquid in the environment is drawn into the counterweight area 20, thereby increasing the weight of the counterweight 19, so that the detection mechanism can be retracted and released more smoothly. When the measuring sensor 31 is extended by the electric push rod 32 to measure the water temperature, the piston plate 21 is pulled by the operating rod 35 to move in the counterweight area 20, and the liquid in the counterweight area 20 is discharged to complete the weight reduction, so that the detection mechanism can be relieved when it is suspended for a long time for water temperature measurement, thereby reducing the load on the cable 3. like Fig.11 and Fig.12 As shown, the auxiliary unit also includes: A plurality of sliding plates 24 are slidably disposed in a plurality of through-areas 16, each through-area 16 is provided with a lifting area cooperating with the sliding plate 24, a first rack area 25 is disposed on one side of each sliding plate 24, and a second rack area 26 is disposed on the other side of each sliding plate 24; Multiple conversion shafts 27 are rotatably arranged at the top of the multiple penetration areas 16. The multiple conversion shafts 27 are each provided with a balancing arm 28. The balancing arm 28 can be made of a buoyancy material or a metal material and can be freely set according to actual measurement requirements. The balancing arm 28 can follow the conversion shaft 27 and hide in the penetration area 16. A plurality of conversion gears 29 are fixedly sleeved outside the plurality of conversion shafts 27, and each conversion gear 29 is meshed and transmission-connected with the second rack area 26; It is worth noting that: at the same time, under normal conditions, when the measuring sensor 31 is hidden in the storage area 18, the multiple balance arms 28 are hidden in the penetration area 16 to avoid interference with the downward movement of the circular housing 14. When the measuring sensor 31 is extended for measurement, under this path, the electric push rod 32 synchronously controls the control disk 33 to move downward, carrying multiple control arms 37 and the control gear 38 to move downward synchronously. Since the control gear 38 is meshed with the guide tooth plate 36 and the No. 1 rack area 25, the control gear 38 pulls the sliding plate 24 to move downward synchronously. Due to the design of the guide tooth plate 36, the control gear 38 is moved downward through the guide tooth plate 36. The guide generates a rotation amount, so that the sliding plate 24 will superimpose a rotation amount of the control gear 38, so that the sliding plate 24 expands the stroke, and the control sliding plate 24 moves a larger distance. In this process, the second rack area 26 on the control plate engages with the conversion gear 29, so that the second rack area 26 can control the conversion gear 29 and the balance arm 28 to rotate, so that the originally hidden balance arm 28 extends out of the penetration area 16, and the contact area between the circular shell 14 and the liquid can be increased through the balance arm 28, the circular shell 14 can be kept stable, and the balance can be maintained in the water temperature measurement in the hovering state, which is conducive to the accurate measurement of the water temperature; A plurality of buoyancy airbags 30 are arranged on the top of the plurality of balancing arms 28. A communication pipe is installed on one side of the bottom of each buoyancy airbag 30. The buoyancy airbag 30 is made of a buoyancy material. The buoyancy airbag 30 after being inflated can enhance the buoyancy effect. It is worth noting that: at the same time, under normal conditions, when the measuring sensor 31 is hidden in the storage area 18, the multiple buoyancy airbags 30 are in a contracted state, and the No. 1 piston member 40 is separated from the control plate 33. When the measuring sensor 31 is extended for measurement, the control plate 33 moves downward to squeeze the No. 1 piston member 40, and the gas in the squeezing chamber 39 is sent into the multiple buoyancy airbags 30, so that the buoyancy airbags 30 expand, further improving the balancing effect of the balance arm 28; like Fig.13 As shown, in an embodiment of the present invention, the detection unit includes: The measuring sensor 31 is slidably disposed in the storage area 18. The measuring sensor 31 is specifically replaced by a water temperature sensor or other sensors capable of measuring water temperature. The measuring sensor 31 is electrically connected to the cable 3 through a wiring harness, and the electric push rod 32 is also electrically connected to the cable 3. The electric push rod 32 is arranged at the top of the storage area 18 through a bracket, and the output end of the electric push rod 32 is transmission-connected to the measuring sensor 31; In an embodiment of the present invention, the control unit includes: The control panel 33 is arranged above the electric push rod 32, and a plurality of fixing rods 34 are arranged between the bottom of the control panel 33 and the measuring sensor 31; The operating rod 35 is fixedly arranged on the top of the control panel 33, and the top of the operating rod 35 slides through the circular housing 14, the counterweight 19 and is in transmission connection with the piston plate 21 of the auxiliary unit; A plurality of guide tooth plates 36 are arranged in a circular array in the adjustment area 15; A plurality of control arms 37 are arranged in a circular array on the upper surface of the control plate 33. A control gear 38 is rotatably mounted on the top of each control arm 37. Each control gear 38 is respectively engaged and transmission-connected with the adjacent guide toothed plate 36 and the first rack area 25. It is worth noting that: when the detection unit is controlled: by providing a control unit, under normal conditions, the electric push rod 32 controls the measuring sensor 31 to be hidden in the storage area 18 to avoid the detection mechanism, so that the detection mechanism will not be hit by foreign objects in the process of storage and release, thereby improving safety and avoiding damage. It can also avoid interference from foreign objects during the process of storage and release, optimize the detection process, and there is no need to expose the measuring sensor 31 for a long time. Subsequently, the electric push rod 32 is controlled to work and push the measuring sensor 31 out of the storage area 18 to measure the water temperature. The operation is flexible and easy to control. The control unit also includes: The extrusion chamber 39 is arranged at the bottom of the adjustment area 15 through a bracket. A No. 1 piston member 40 is installed in a sliding and sealing manner in the extrusion chamber 39, and the No. 1 piston member 40 is arranged in cooperation with the lower surface of the control plate 33. A sliding area that cooperates with the No. 1 piston member 40 is opened in the extrusion chamber 39. A return spring 41 is arranged between the No. 1 piston member 40 and the extrusion chamber 39. The return spring 41 pushes the No. 1 piston member 40 to move in the direction of moving out of the extrusion chamber 39. A certain amount of gas is injected into the extrusion chamber 39, which is conducive to the subsequent control of multiple buoyancy airbags 30; A plurality of delivery pipes 42 are connected and arranged around the bottom of the extrusion chamber 39, and the plurality of delivery pipes 42 are connected to the plurality of intercommunication pipes through spring pipes respectively; like Fig.14 , Fig.15 and Fig.16 As shown, in the embodiment of the present invention, the dynamic cleaning unit includes: The annular member 43 is disposed at the bottom of the circular housing 14. An annular scraper 44 is detachably mounted on the inner wall of the annular member 43. The annular scraper 44 is used to scrape and clean the measuring sensor 31. The annular cavity 45 is arranged at the top of the annular member 43. An annular cover plate 46 is installed on the top of the annular cavity 45 for rotation and sealing. A plurality of nozzles are arranged in a circular array on the inner wall of the annular cavity 45. The annular cover plate 46 can be detachably fixedly connected to the circular housing 14 through a bracket so that the annular cover plate 46 remains stable. An outer gear ring 47 is sleeved on the outside of the annular cavity 45. A driving circular cavity 48 is provided at one side of the bottom of the circular housing 14. A driving impeller 49 is rotatably and sealably installed in the driving circular cavity 48. A driving gear 50 meshing with the outer gear ring 47 is installed on the top of the driving impeller 49. The third pipe 51 is connected to one side of the driving circular cavity 48, and a third one-way valve for controlling the one-way introduction of the medium into the driving circular cavity 48 is installed at the end of the third pipe 51. The third pipe 51 is connected to the second pipe 23 through a flexible pipe, and a fourth pipe 52 is connected to the other side of the driving circular cavity 48. A fourth one-way valve for controlling the one-way discharge of the medium from the driving circular cavity 48 is installed at the end of the fourth pipe 52. A connecting pipe is provided between the fourth pipe 52 and the annular cover plate 46, and the connecting pipe is interconnected with the annular cavity 45. It is worth noting that: when the detection unit is assisted in cleaning: by providing a dynamic cleaning unit and the design of the annular member 43, the extension and reset of the measuring sensor 31 both need to contact the annular scraper 44, and the scraping and cleaning of the measuring sensor 31 is completed by the annular scraper 44, thereby ensuring the cleanliness of the measuring sensor 31. At the same time, when the measuring sensor 31 is extended for measurement, the liquid in the counterweight area 20 is sent into the No. 3 tube 51 via the No. 2 tube 23, and the liquid drives the driving impeller 49 and the driving gear 50 to rotate, driving the outer gear ring 47 and the annular cavity 45 to rotate, and at the same time drives the liquid in the circular cavity 48 to be sent into the annular cavity 45 via the No. 4 tube 52, and the liquid is sprayed through multiple nozzles, thereby accelerating the flow of liquid near the measuring sensor 31 and performing liquid turbulence. At the same time, multiple nozzles rotate with the annular cavity 45, thereby further enhancing the turbulence effect, and completing the impact on the measuring sensor 31 through the water flow, thereby further enhancing the cleaning effect.
