Description

Technical Field

[0001] The utility model belongs to the technical field of geothermal energy application, and in particular relates to a geothermal energy exploration depth measuring device. Background Art

[0002] The heat contained in the earth's interior. It has two different sources, one from the outside of the earth and one from the inside of the earth. The heat energy of the earth's surface mainly comes from solar radiation. In the range of about 15 to 30 meters below the surface, the temperature changes significantly with the change of day and night and the four seasons. This part of heat energy is called "external heat". The exploitation of geothermal energy requires drilling wells on the surface and then burying U-shaped pipes to achieve the exchange of cold and heat.

[0003] The drilling depth will vary depending on the geographical environment. Therefore, the drilling depth needs to be measured during geothermal energy exploration to ensure the accuracy of pipeline burial. However, due to the drilling depth of tens or hundreds of meters, it can only be done by lowering the measuring rope. After the measurement, a large amount of muddy water will remain on the surface of the measuring rope. At this time, winding and recycling the measuring rope will cause the surface scale to be contaminated, affecting the next use. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] Please refer to Figure 1-Figure 5 As shown, a geothermal energy exploration depth measuring device includes a bottom plate 1 and a sleeve 4. Fixing mechanisms 5 are slidably installed on both sides of the bottom plate 1. The bottom plate 1 is placed at the wellhead. Brackets 2 are symmetrically arranged on the upper surface of the bottom plate 1. A winding drum 3 is installed between the two brackets 2 through a bearing. The winding drum 3 is in a suspended state so that the winding drum 3 can rotate in any direction when the line is retracted and released. The sleeve 4 is vertically installed at the center of the bottom plate 1 and penetrates the bottom plate 1. A measuring rope 31 is wound on the surface of the winding drum 3. Scale labels are evenly arranged on the surface of the measuring rope 31. By observing the scale The value of the label is used to judge the measuring depth. The measuring rope 31 passes through the sleeve 4. A counterweight 32 is arranged at the bottom of the measuring rope 31. The top and bottom of the counterweight 32 are both in a cone shape to facilitate guidance when moving up and down. A cone 41 is arranged on the top of the sleeve 4. A notch groove 42 is opened on one side of the sleeve 4 and the cone 41. When squeezed, the sleeve 4 and the cone 41 can be tightened to scrape off the mud and water on the surface of the measuring rope 31 through the inner wall of the cone 41. The inner wall of the cone 4 is small at the top and large at the bottom, so that the mud and water on the surface of the measuring rope 31 can be scraped off through the narrow opening at the top when tightened.

[0023] Among them, a fixing bolt 6 is provided on the side of the upper surface of the base plate 1 away from the notch groove 42, and two movable cylinders 7 are rotatably installed on the surface of the fixing bolt 6. The two movable cylinders 7 are respectively placed on both sides of the sleeve 4, and a movable rod 71 is slidably installed on one end of the movable cylinder 7 away from the fixing bolt 6. Two mounting plates 8 are provided on the side of the upper surface of the base plate 1 away from the fixing bolt 6, and a double-threaded rod 9 is installed between the two mounting plates 8 through a bearing. The double-threaded rod 9 penetrates the front mounting plate 8, and a knob is provided at the front end of the double-threaded rod 9. Moving blocks 10 are symmetrically screwed on the surface of the double-threaded rod 9. The ends of the two movable rods 71 ​​away from the movable cylinder 7 are respectively hinged on the moving blocks 10. Rotating the double-threaded rod 9 can control the two moving blocks 10 to approach or move away synchronously. When the two moving blocks 10 approach synchronously, the sleeve 4 can be squeezed by the movable cylinder 7 so that it is pressed inward, and the movable cylinder 7 and the movable rod 71 can make up for the distance difference when the angle changes.

[0024] Please refer to Figure 2 Figure 5 As shown, a limiting groove 11 is opened downward on the surface of the bottom plate 1, and a positioning protrusion 44 is provided on the side of the sleeve 4 away from the notch groove 42. The positioning protrusion 44 is placed on the inner side of the limiting groove 11 to ensure that the sleeve 4 shrinks inward when squeezed to prevent the sleeve 4 from rotating due to uneven collection.

[0025] Please refer to Figure 3 As shown, positioning protrusions 43 are symmetrically arranged below the outer surface of the sleeve 4. The two positioning protrusions 43 are respectively placed on both sides of the notch groove 42. The positioning protrusions 43 are placed on the lower surface of the bottom plate 1 to ensure the stable installation of the sleeve 4 and prevent it from falling off.

[0026] Please refer to Figure 1 and Figure 4 As shown, the fixing mechanism 5 includes a movable plate 51, and a telescopic rod 52 is symmetrically arranged on one side of the movable plate 51. The telescopic rod 52 is slidably installed on the side surface of the bottom plate 1. A rotating shaft 53 is installed on the side surface of the movable plate 51 away from the telescopic rod 52 through a pin shaft. Embedded rods 54 are evenly arranged on the bottom of the rotating shaft 53. When installing, the embedded rods 54 are inserted into the soil on both sides of the drilling to ensure the stability of the equipment installation, and can be stored when not in use.

[0027] Please refer to Figure 1 As shown, a docking square head 33 is coaxially arranged on one side of the winding drum 3. The docking square head 33 is placed on the front side of the bracket 2 and docked with the handle through the outside to control the winding drum 3.

[0028] The working principle of the utility model is as follows: first, pull the fixing mechanism 5 outward so that the telescopic rod 52 can slide outward, and rotate the rotating shaft 53 so that the embedded rod 54 is vertically downward. During installation, ensure that the bottom plate 1 spans above the wellhead, and insert the embedded rod 54 to ensure the stability of the equipment installation. Place the counterweight 32 inside the detection well, and drive the winding drum 3 to rotate through the cooperation of the external wrench and the docking square head 33 to achieve the release of the measuring rope 31. When releasing the wire, the sleeve 4 does not squeeze the measuring rope 31, but only guides the measuring rope 31 to ensure that the measuring rope 31 is released downward along the center of the equipment. The scale surface on the surface of the rope 31 is used to judge the depth. Conversely, after the measurement is completed, the winding drum 3 is rotated in the opposite direction to realize the winding, and the knob at the end of the double-threaded rod 9 is rotated to drive the two moving blocks 10 to approach each other, thereby reducing the angle component between the two movable cylinders 7, and then squeezing the sleeve 4 to make the sleeve 4 deform inward, and the mud and water on the surface of the measuring rope 31 are scraped off by the deformed cone cylinder 41 to ensure that the measuring rope 31 is in a clean state when wound on the winding drum 3, and the positioning protrusion 44 on the side away from the notch groove 42 is placed inside the limit groove 11 to ensure the stability of the sleeve 4 when it is deformed.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
