Description

Technical Field

[0001] This utility model belongs to the field of geothermal equipment technology, specifically relating to a geothermal well water level measuring device. Background Technology

[0002] A geothermal well refers to a method and device for generating electricity using geothermal energy or hot spring water with a temperature greater than 30℃ at a depth of about 3500 meters. Geothermal energy is classified into three categories: high-temperature, medium-temperature, and low-temperature. High-temperature geothermal energy exists in the form of steam at temperatures above 150℃; medium-temperature geothermal energy exists in the form of a mixture of water and steam at temperatures between 90℃ and 150℃; and low-temperature geothermal energy exists in the form of warm water, warm-hot water, or hot water at temperatures above 25℃ and below 90℃. During operation, the water level inside the geothermal well needs to be monitored regularly.

[0003] Currently, the method for detecting water levels in geothermal wells typically involves using a rope with a buoyancy block attached to the end. By sending the rope into the well, the rope's weight decreases when the buoyancy block touches the water surface. The length of the rope inside the well is then considered the depth of the liquid level. However, this method, which relies on the human sense of the rope's weight to determine the liquid level, is not only complex to operate but also prone to errors due to its dependence on human perception of rope weight.

[0004] To address the aforementioned issues, this application proposes a geothermal well water level measuring device. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a geothermal well water level measuring device, characterized by accurate measurement and stable lowering of the traction rope.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geothermal well water level measuring device, comprising a support frame and a winding drum, wherein the winding drum is rotatably mounted on the top of the support frame, and a traction rope is wound clockwise around the winding drum from the bottom; a rotating shaft is rotatably mounted at the bottom of the support frame, and a winding drum is provided in the middle of the rotating shaft; the free end of the traction rope is wound around the winding drum once and connected to a buoyancy block; one end of the rotating shaft passes through the support frame and is fitted with a counting wheel, and a telescopic component is provided on the surface of the support frame that abuts against the counting wheel; a trigger is provided at the end of the telescopic component, and a counter electrically connected to the trigger is provided on the support frame.

[0007] As a preferred embodiment of the geothermal well water level measuring device of this utility model, a support plate is retractable at the bottom of the support frame and directly below the buoyancy block.

[0008] In a preferred embodiment of the geothermal well water level measuring device of this utility model, a first guide plate and a second guide plate are respectively provided between the winding drum and the coiling drum and between the coiling drum and the buoyancy block. Both the first guide plate and the second guide plate have a guide hole in the middle for the traction rope to pass through.

[0009] As a preferred embodiment of the geothermal well water level measuring device of this utility model, the winding drum is a rotating structure, and the cross-sectional area of ​​the winding drum gradually decreases from both sides to the middle.

[0010] In a preferred embodiment of the geothermal well water level measuring device of this utility model, the telescopic component includes an installation sleeve disposed on the support frame, a telescopic rod disposed inside the installation sleeve, a compression ball disposed at one end of the telescopic rod, the other end of the telescopic rod being aligned with the trigger, and a compression spring disposed on the outer side of the telescopic rod.

[0011] As a preferred embodiment of the geothermal well water level measuring device of this utility model, the outer circumference of the counting wheel is provided with several arc-shaped grooves at equal intervals, and the center of the arc-shaped groove is located on the same plane as the axis of the telescopic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the buoyancy block in this utility model will reduce the tension of the traction rope after contacting the water surface.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown;

[0022] A geothermal well water level measuring device includes a support frame 1 and a reel 2. The reel 2 is rotatably mounted on the top of the support frame 1, and a traction rope 3 is wound clockwise around the reel 2 from the bottom. A rotating shaft 4 is rotatably mounted at the bottom of the support frame 1, and a winding drum 5 is mounted in the middle of the rotating shaft 4. The free end of the traction rope 3 is wound around the winding drum 5 once and connected to a buoyancy block 6. One end of the rotating shaft 4 passes through the support frame 1 and is fitted with a counting wheel 7. A telescopic component 8 is provided on the surface of the support frame 1 to abut against the counting wheel 7. A trigger 9 is provided at the end of the telescopic component 8, and a counter 10 electrically connected to the trigger 9 is provided on the support frame 1. A support plate 11 is retractable at the bottom of the support frame 1 and directly below the buoyancy block 6.

[0023] It should be noted that in this embodiment, the counter 10 is composed of a basic counting unit and a control gate. When the trigger 9 is squeezed, it can generate a clock pulse. The counter 10 counts the clock pulses to record the number of times the trigger 9 is squeezed.

[0024] In this implementation scheme: after the buoyancy block 6 contacts the water surface, the tension on the traction rope 3 will decrease. At this time, the counting wheel 7 cannot squeeze and rotate the telescopic component 8, thus ensuring the lowering accuracy. In addition, the counter 10 can count the number of times the trigger 9 is pressed, thereby calculating the number of rotations of the counting wheel 7. Then, the lowering distance of the traction rope 3 can be calculated by the circumference of the winding drum 5.

[0025] In an optional embodiment, a first guide plate 12 and a second guide plate 13 are respectively provided between the winding drum 2 and the winding drum 5 and between the winding drum 5 and the buoyancy block 6. The first guide plate 12 and the second guide plate 13 are each provided with a guide hole for the traction rope 3 to pass through.

[0026] In this embodiment, the wire holes on the first guide plate 12 and the second guide plate 13 are misaligned to prevent the traction rope 3 from stacking on each other when it is wound on the winding drum 5. Stacking of the traction rope 3 will affect the smoothness of its lowering.

[0027] In an optional embodiment, the winding drum 5 is a rotating structure, and the cross-sectional area of ​​the winding drum 5 gradually decreases from both sides to the middle.

[0028] In this embodiment, the minimum circumferential outer diameter of the winding drum 5 can be set to an integer multiple of ten, which facilitates the calculation of the lowering distance of the traction rope 3. At the same time, the conical structure of the winding drum 5 ensures that the traction rope 3 is drawn towards the center, thereby ensuring the accuracy of the calculation of the lowering distance of the traction rope 3.

[0029] like Figure 3 As shown;

[0030] In an optional embodiment, the telescopic assembly 8 includes a mounting sleeve 801 disposed on the support frame 1, a telescopic rod 802 disposed inside the mounting sleeve 801, a compression ball 803 disposed at one end of the telescopic rod 802, the other end of the telescopic rod 802 being aligned with the trigger 9, and a compression spring 804 being sleeved on the outer side of the telescopic rod 802.

[0031] In this embodiment: the traction rope 3 uses friction to drive the winding drum 5 and the rotating shaft 4 to rotate. At this time, the counting wheel 7 rotates and squeezes the telescopic rod 802. The telescopic rod 802 retracts and presses the trigger 9 once.

[0032] like Figure 4 As shown;

[0033] In an optional embodiment, a plurality of arc-shaped grooves 701 are provided at equal intervals on the outer circumference of the counting wheel 7, and the center of the arc-shaped grooves 701 and the axis of the telescopic rod 802 are located on the same plane.

[0034] In this embodiment: when the squeezing ball 803 enters the arc-shaped groove 701, the telescopic rod 802 resets. When the buoyancy block 6 contacts the water surface, the tension on the traction rope 3 decreases. At this time, the counting wheel 7 cannot squeeze the telescopic rod 802, and the squeezing ball 803 enters the arc-shaped groove 701.

[0035] It should be noted that the radius of the arc-shaped groove 701 is greater than the radius of the extrusion ball 803, and the depth of the arc-shaped groove 701 is less than its radius. The number of arc-shaped grooves 701 can be set to five or ten. The number of times the trigger 9 is pressed divided by the number of arc-shaped grooves 701 is the number of rotations of the winding drum 5. The number of rotations of the winding drum 5 multiplied by its minimum circumference size is the lowering distance of the traction rope 3.

[0036] The working principle and usage process of this utility model are as follows: The traction rope 3 is wound around the winding drum 5, ensuring the bottom end is exposed. Then, the free end of the traction rope 3 passes through the first guide plate 12 and winds one turn around the minimum diameter of the winding drum 5. Next, the traction rope 3 passes through the second guide plate 13 and connects to the buoyancy block 6. Pulling out the support plate 11 lowers the buoyancy block 6. At this time, the buoyancy block 6 exerts a pulling force on the traction rope 3 due to its own weight. The traction rope 3 uses friction to drive the winding drum 5 and the rotating shaft 4 to rotate. Simultaneously, the counting wheel 7 rotates and counts... The telescopic rod 802 is squeezed, and the telescopic rod 802 retracts to press the trigger 9 once. When the squeezing ball 803 enters the arc-shaped groove 701, the telescopic rod 802 resets. This process is repeated to repeatedly press the trigger 9. When the buoyancy block 6 contacts the water surface, the tension on the traction rope 3 decreases. At this time, the counting wheel 7 can no longer squeeze the telescopic rod 802, and the squeezing ball 803 enters the arc-shaped groove 701. The lowering distance of the traction rope 3 can be calculated by counting the number of rotations of the winding drum 5.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
