Description

Technical Field

[0001] The present invention relates to the field of exploration and measurement technology, 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 water level and deep water temperature observation methods. These require high placement of water temperature sensors, which must meet the following requirements: 1. Areas with large water temperature gradients; 2. Areas with low water temperature background noise; 3. Areas with significant water temperature tidal effects. This requires precise measurement of the water temperature gradient in the wells.

[0003] 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 using a simple manually operated 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.

[0004] A deep well water temperature gradient measuring device for seismic observation is disclosed in the patent application with reference publication number CN216925847U. The deep well water temperature gradient measuring device for seismic observation utilizes a retraction and extension drive mechanism to drive the rotation of the sensor retraction and extension mechanism, which can realize the retraction and extension of the cable, thereby adjusting the height position of the temperature sensor. The depth of the cable lowered is measured by the depth measuring mechanism, and the depth of the temperature sensor entering the water can be calculated. The depth of the temperature sensor entering the water is then combined with the data measured by the temperature sensor to realize the gradient measurement of the water temperature.

[0005] Currently, water temperature gradient measurement is mostly done manually or by a retractable mechanism. For example, the above-mentioned water temperature measuring device also uses a retractable mechanism in conjunction with a temperature sensor to complete the measurement work. However, the temperature sensor on the current water temperature measuring device is mostly directly exposed and inserted into the deep well. Therefore, during the retraction and extension process, the temperature sensor is easily damaged by contact with foreign objects. Moreover, if the temperature sensor is exposed for a long time, a large amount of debris is easily accumulated, which affects the accurate measurement of water temperature, makes it impossible to collect water temperature gradient data in an orderly manner, and affects the subsequent data analysis results.

[0006] 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 during water temperature measurement, 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.

[0049] 1.

[0070] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0071] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0072] 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 provided 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 drive 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 provided at the bottom of the assembly frame 1, and slidable ground nails are provided at the four corners of the assembly frame 1 to be fixed to the ground. A control cabinet is installed on one side of the top of the assembly frame 1, and further includes:

[0073] The receiving mechanism is provided on the assembly frame 1 to complete the retraction and extension 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 retraction and extension data of the cable 3, and the two limiting units are used to complete the active guidance and restriction of the cable 3;

[0074] A guide mechanism is provided in the detection area to complete the guide control operation of the cable 3. The guide mechanism includes an adjustment frame 5, a movable pulley 6 is slidably provided in the adjustment frame 5, a plurality of connection holes are provided side by side on the adjustment frame 5, and a connecting bolt is slidably passed through the movable pulley 6. The connecting bolt passes through the corresponding connection holes to restrict the movable pulley 6 to the adjustment frame 5;

[0075] 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.

[0076] 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.

[0077] Embodiment 2: Based on the receiving mechanism provided in embodiment 1, this embodiment provides a further technical solution for the receiving mechanism.

[0078] like Figure 5 and Figure 6 As shown, the perception unit includes:

[0079] A rectangular frame 7 is provided on the assembly frame 1. A rotating shaft 8 is rotatably mounted on the rectangular frame 7 via a bearing. A rotation sensor 9 is connected to the rotating shaft 8 on one side of the rectangular frame 7. A torque sensor 10 is connected to the rotating shaft 8 on the other side of the rectangular frame 7.

[0080] A fixed pulley 11 is fixedly sleeved on the outside of the rotating shaft 8 to guide the cable 3;

[0081] In the embodiment of the present invention, each limiting unit includes:

[0082] The limiting frame 12 is provided on the rectangular frame 7;

[0083] Two guide wheels 13 are symmetrically arranged at the top and bottom of the limiting frame 12 to actively guide the cable 3;

[0084] It is worth noting that when the detection mechanism is retracted and extended: by providing a receiving mechanism, the cable 3 passes through the guide wheels 13 of the two limiting units, which can complete stable limiting guidance of the cable 3, and at the same time, the cable 3 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 extended. At the same time, when the fixed pulley 11 rotates, the speed sensor 9 can accurately obtain the release length data of the cable 3, which is conducive to controlling the lowering depth of the detection mechanism. The torque sensor 10 obtains the torque of the cable 3 when it is retracted and extended, and can accurately judge the stability of the retraction and extension 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 extension process, and the forward and reverse CNC motor 4 is synchronously controlled to stop running, and the operator is warned to take active intervention, thereby improving the safety of retraction and extension. 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 extension position of the detection mechanism, enriching the detection range, and facilitating free adjustment.

[0085] Embodiment 3: Based on the detection mechanism provided in embodiment 1, this embodiment provides a further technical solution for the detection mechanism.

[0086] like Figure 7 and Figure 8 As shown, the housing includes:

[0087] A circular housing 14 is provided at the bottom of the auxiliary unit. The circular housing 14 is made of metal. An adjustment area 15 is provided in the middle of the circular housing 14. A plurality of through areas 16 communicating with the adjustment area 15 are provided in a circular array around the circular housing 14.

[0088] The isolation plate 17 is spaced apart and arranged at the bottom of the circular housing 14 by a bracket;

[0089] The storage area 18 is provided at the bottom of the circular housing 14 and communicates with the adjustment area 15;

[0090] like Figure 9 and Figure 10 As shown, in an embodiment of the present invention, the auxiliary unit includes:

[0091] The counterweight 19 is provided 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 extended.

[0092] 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.

[0093] A No. 1 pipe 22 is connected to one side of the bottom of the counterweight area 20. A No. 1 one-way valve is installed at the end of the No. 1 pipe 22 to control the one-way entry of the medium into the counterweight area 20. A No. 2 pipe 23 is connected to the other side of the bottom of the counterweight area 20. A No. 2 one-way valve is installed at the end of the No. 2 pipe 23 to control the one-way exit of the medium from the counterweight area 20.

[0094] 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 retraction and extension. 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 operating rod 35 pushes the piston plate 21 to move upward in the counterweight area 20, and the liquid in the environment is drawn into the counterweight area 20, which increases the weight of the counterweight 19, so that the detection mechanism can be retracted and extended more smoothly. When the measuring sensor 31 is extended by the electric push rod 32 to measure the water temperature, the operating rod 35 pulls the piston plate 21 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.

[0095] like Figure 11 and Figure 12 As shown, the auxiliary unit also includes:

[0096] Multiple sliding plates 24 are slidably disposed in multiple through-areas 16. Each through-area 16 has a lifting area that cooperates 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.

[0097] Multiple conversion shafts 27 are rotatably disposed at the top of the multiple penetration areas 16. Each of the conversion shafts 27 is provided with a balancing arm 28. The balancing arm 28 can be made of a buoyant material or a metal material and can be freely set according to actual measurement requirements. The balancing arm 28 can be hidden in the penetration area 16 along with the conversion shaft 27;

[0098] Multiple conversion gears 29 are fixedly sleeved on the outside of the multiple conversion shafts 27, and each conversion gear 29 is meshed and driven with the second rack area 26;

[0099] 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 all 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 engaged with the guide gear plate 36 and the No. 1 rack area 25, the control gear 38 pulls the sliding plate 24 downward synchronously. Due to the design of the guide gear plate 36, the control gear 38 passes through the guide gear plate 36 during the downward movement. 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 controls the sliding plate 24 to move a greater distance. During 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 through area 16. The balance arm 28 can increase the contact area between the circular housing 14 and the liquid, and can maintain the stability of the circular housing 14. It can maintain balance during water temperature measurement in a hovering state, which is conducive to accurate water temperature measurement.

[0100] Multiple buoyancy airbags 30 are arranged on top of multiple balance arms 28. An interconnecting pipe is installed on one side of the bottom of each buoyancy airbag 30. The buoyancy airbag 30 is made of buoyant material. When inflated, the buoyancy airbag 30 can enhance the buoyancy effect.

[0101] 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, causing the buoyancy airbags 30 to expand, further improving the balancing effect of the balance arm 28;

[0102] like Figure 13 As shown, in an embodiment of the present invention, the detection unit includes:

[0103] 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;

[0104] 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;

[0105] In an embodiment of the present invention, the control unit includes:

[0106] 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;

[0107] The operating rod 35 is fixedly mounted 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;

[0108] A plurality of guide tooth plates 36 are arranged in a circular array within the adjustment area 15;

[0109] 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 with the adjacent guide gear plate 36 and the first rack area 25.

[0110] It is worth noting that: when the detection unit is controlled: by providing a control unit, under normal circumstances, the electric push rod 32 controls the measuring sensor 31 to be hidden in the storage area 18 to complete the avoidance, so that the detection mechanism will not be hit by foreign objects during the retraction and extension, thereby improving safety and avoiding damage problems. It can also avoid interference from foreign objects during the retraction and extension process, optimizing 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.

[0111] The control unit also includes:

[0112] The extrusion chamber 39 is mounted at the bottom of the adjustment area 15 via a bracket. A piston member 40 is slidably and sealably mounted in the extrusion chamber 39. The piston member 40 cooperates with the lower surface of the control panel 33. A sliding area is provided in the extrusion chamber 39 to cooperate with the piston member 40. A return spring 41 is provided between the piston member 40 and the extrusion chamber 39. The return spring 41 pushes the piston member 40 toward the direction of moving out of the extrusion chamber 39. A fixed amount of gas is injected into the extrusion chamber 39, which facilitates the subsequent control of the multiple buoyancy airbags 30.

[0113] Multiple delivery pipes 42 are connected and arranged around the bottom of the extrusion chamber 39. The multiple delivery pipes 42 are connected to the multiple interconnecting pipes through spring pipes respectively;

[0114] like Figure 14 、 Figure 15 and Figure 16 As shown, in an embodiment of the present invention, the dynamic cleaning unit includes:

[0115] The annular member 43 is provided at the bottom of the circular housing 14 , and an annular scraper 44 is detachably mounted on the inner wall of the annular member 43 , and the annular scraper 44 is used to scrape and clean the measuring sensor 31 ;

[0116] An annular cavity 45 is provided at the top of the annular member 43. An annular cover plate 46 is mounted on the top of the annular cavity 45 for rotational 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 via a bracket to maintain the stability of the annular cover plate 46.
