Description

Technical Field

[0001] The utility model relates to the technical field of geothermal water level measurement, in particular to a geothermal water level measurement device. Background Art

[0002] Geothermal energy refers to the heat energy inside the earth. Its extraction usually involves drilling technology. Steam and high-temperature hot water are collected underground through drilling, and then brought to the surface. This heat energy can be used for power generation, heating, cooling and other purposes. Before the collection process of the high-temperature liquid stored in the geothermal well begins, it is usually necessary to use a specific water level measuring device to complete the measurement of the high-temperature liquid level in the well, so as to further formulate relevant collection plans and complete the collection of geothermal energy.

[0003] For example, the prior art provides a geothermal water level measuring device, patent number: CN218121081U, which places a measuring unit into a well. When the measuring unit is vertical under the action of a plumb bob, a resistance meter is used to measure the resistance between the first wire and the second wire. The resistance at this time is the parallel resistance of all the remaining resistors above the geothermal water level. The number of remaining resistors can be calculated according to the series resistance formula. Since the spacing between each group of short contact points is the same, the height of the geothermal water surface from the ground, that is, the water level of the geothermal water, can be obtained by multiplying the spacing between each group of short contact points by the number of remaining resistors.

[0004] However, in the prior art, when detecting the water level in an unknown area, the length of the measuring unit to be prepared is uncertain, and a longer measuring unit needs to be prepared to cope with different water level changes. In addition, the measuring unit cannot be completely stored, which greatly increases the difficulty of transportation. Utility Model Content

[0007] Preferably, a brake motor with a main shaft fixedly connected to the rotating shaft of the winding reel is provided on the outer surface of the box body.

[0008] Preferably, a bidirectional threaded rod is rotatably connected to the inner side of the frame and close to the box body, and a first motor is arranged on the bidirectional threaded rod.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-4 As shown, a geothermal water level measuring device comprises a box body 1, a cable reel 11 is rotatably connected inside the box body 1, a cable 3 is wound on the cable reel 11, and a water level sensor 8 for monitoring the water level in the geothermal well is fixedly connected to the end of the cable 3, a wire seat 13 is fixedly connected above the outer surface of the box body 1, a fixed pulley 2 is rotatably connected to the wire seat 13, a wire tube 4 is fixedly connected below the wire seat 13, a frame 9 is integrally formed on the outer surface of the box body 1 below the wire tube 4, two symmetrically arranged clamping worm gears 5 are slidably connected to the frame 9, a bidirectional worm 15 meshing with the clamping worm gear 5 is rotatably connected to the frame 9, one of the end faces of the clamping worm gear 5 is fixedly connected to a turn detector 7, and a second motor 17 whose main shaft is fixedly connected to the bidirectional worm 15 is provided at both ends of the frame 9, the cable 3 extends outward through the box body 1, and passes through the fixed pulley 2, the wire tube 4 and the two clamping worm gears 5 in sequence;

[0023] A brake motor 19 is disposed on the outer surface of the box body 1 and has a main shaft fixedly connected to the rotating shaft of the winding drum 11 .

[0024] The specific working process of this scheme is as follows: pull the cable 3 out of the box 1, pass through the wire seat 13, the fixed pulley 2 and the wire tube 4 in sequence, and clamp it between the clamping worm wheel 5. Then, the second motor 17 drives the bidirectional worm 15 to rotate, and the clamping worm wheel 5 rotates and pushes the cable 3 and the water level sensor 8 located at the bottom of the cable 3 to move to the bottom of the geothermal well. The number of turns detector 7 starts to record the number of turns along with the rotation of the clamping worm wheel 5 until the water level sensor 8 completes contact with the liquid surface in the geothermal well. At this time, the number of turns detector 7 stops recording the number of turns, and the number of turns recorded by the number of turns detector 7 and the inner diameter of the clamping worm wheel 5 are combined to complete the calculation of the circumference. The circumference is multiplied by the number of turns, and the result obtained is the water level height of the geothermal well.

[0025] In addition, the present invention drives the cable reel 11 to rotate by the brake motor 19 to complete the storage and release of the cable 3, thereby facilitating the transportation and transfer of the entire device.

[0026] like Figure 3 and Figure 4 As shown, a bidirectional threaded rod 18 is rotatably connected to the inner side of the frame 9 and close to the box body 1, and a first motor 6 is arranged on the bidirectional threaded rod 18;

[0027] Two symmetrical moving blocks 12 are threadedly connected to the bidirectional threaded rod 18, and the moving blocks 12 are rotatably connected to meshing gears 14, which are fixedly connected to the clamping worm gear 5, and the inner diameter of the clamping worm gear 5 is the same as the radius of the meshing gear 14;

[0028] An electric telescopic rod 10 is fixedly connected to the frame 9 , and the extended end thereof is directly connected to the outer surface of the second motor 17 .

[0029] The specific working process of this scheme is as follows: the electric telescopic rod 10 pushes the bidirectional worm 15 to move upward and disengage from the tooth surface of the clamping worm wheel 5. At this time, the first motor 6 drives the bidirectional threaded rod 18 to rotate, and the moving block 12 drives the meshing gear 14 and the clamping worm wheel 5 to complete the movement toward or away from each other on the bidirectional threaded rod 18 until the cable 3 is clamped. After completion, the telescopic end of the electric telescopic rod 10 is retracted and meshed with the clamping worm wheel 5 again, so that the distance between the clamping worm wheels 5 can be adjusted, so as to achieve the effect of clamping cables 3 of different radii.

[0030] like Figure 3 As shown, a baffle 16 is rotatably connected above the wire seat 13 and located on the outer surface of the box body 1 , and the baffle 16 covers the fixed pulley 2 , the wire tube 4 and the frame 9 .

[0031] The purpose of this solution is to rotate the baffle 16 until it covers the fixed pulley 2, the wire tube 4 and the frame 9, thereby blocking the core part of the device from the outside world, preventing the device from being affected by rain, snow and windy sand, and extending the service life of the device.

[0032] Working principle: Before the water level measurement begins, the electric telescopic rod 10 drives the bidirectional worm 15 to disengage from the tooth surface of the clamping worm wheel 5, and the second motor 17 drives the bidirectional threaded rod 18 to rotate, and drives the moving block 12 and the upper meshing gear 14 to complete the separation or movement until the cable 3 is clamped. After the clamping is completed, the bidirectional worm 15 is retracted again and meshed with the clamping worm wheel 5;

[0033] After the above work is completed, the brake motor 19 drives the winding drum 11 to release the cable 3, and the second motor 17 rotates at the same time, prompting the bidirectional threaded rod 18 to drive the clamping worm wheel 5 and the meshing gear 14 to rotate, so as to pull the cable, and the number of turns detector 7 on the end face of the meshing gear 14 records the number of turns, until the water level sensor 8 at the bottom of the cable 3 contacts the liquid surface in the geothermal well to be measured, the water level sensor sends a signal outward and the number of turns detector 7 stops working at this time, at this time, the circumference of the inner core gear is calculated in combination with the radius of the meshing gear 14, and the circumference is multiplied by the number of turns measured by the number of turns detector 7, and the result is the water level data of the geothermal well to be measured;

[0034] For example, assuming that the result finally recorded by the number of turns detector 7 is 5.5 turns, and the radius of the meshing gear 14 is 1 meter, then the water level result at this time is 2πrX5.5≈11×3.14=34.54 meters;

[0035] In addition, it should be noted that in this solution, the speed at which the clamping gear drags the cable 3 is the same as the speed at which the upper brake motor 19 drives the cable reel 11 to release the cable, so as to ensure that the cable 3 will not be damaged by dragging;

[0036] And the inner diameter of the clamping worm wheel 5 is the same as the radius of the meshing gear 14.

[0037] The wiring diagram of the first motor 6, the number of turns detector 7, the water level sensor 8, the second motor 17 and the brake motor 19 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the first motor 6, the number of turns detector 7, the water level sensor 8, the second motor 17 and the brake motor 19 are no longer explained in detail.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
