Description

Technical Field

[0001] This utility model relates to the field of shallow geothermal energy development technology, specifically to a shallow geothermal sample collection device. Background Technology

[0002] Shallow geothermal energy, also known as shallow geothermal energy, refers to the thermal energy resources within the Earth's interior at a certain depth below the surface, with temperatures below 25°C, that are valuable for development and utilization under current technological and economic conditions. Shallow geothermal energy is a part of geothermal resources and a special type of mineral resource. Its energy mainly comes from solar radiation and the Earth's gradient warming. After being collected and utilized through heat pump technology, shallow geothermal energy can be used to heat buildings, saving 50% to 60% more energy than conventional heating technologies and reducing operating costs by about 30% to 40%. However, the utilization of shallow geothermal energy requires sampling and surveying.

[0003] According to a shallow geothermal sample collection device disclosed in patent publication number CN 210293730 U, the device uses a drive motor to rotate a threaded shaft, causing the threaded shaft to move downwards and the sampling cylinder to drill into the ground surface. The threaded shaft rotates in the opposite direction, causing the threaded shaft to move upwards and the sampling cylinder to retract into the fixed sleeve. Anti-slip strips contact the sample, making it difficult for the sample to fall off. Insulation cotton fitted onto the outer surface of the fixed sleeve keeps the inside of the fixed sleeve warm, thus achieving the goal of keeping the sample warm and making the survey results more accurate. However, after the sample is collected by the sampling cylinder, although the anti-slip strips prevent the sample from falling off, it is not convenient to manually remove the sample, thus affecting the applicability of the device.

[0004] To address this issue, we propose a shallow geothermal sample collection device. Utility Model Content

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a shallow geothermal sample collection device, including a fixed plate 1, a lifting ring 2 fixedly connected to the upper part of the fixed plate 1, a connecting plate 4 fixedly connected to the side wall of the fixed plate 1, a fixed sleeve 5 fixedly connected to the lower part of the fixed plate 1, a support plate 6 fixedly connected to the inner wall of the fixed sleeve 5, a sampling cylinder 7 disposed at the lower part of the support plate 6, an anti-slip strip 8 fixedly connected to the inner wall of the sampling cylinder 7, and a connecting assembly 3 disposed at the lower part of the fixed plate 1. The connecting assembly 3 includes an ejection mechanism 31 disposed at the lower part of the fixed plate 1, and a sampling mechanism 32 disposed at the lower part of the fixed plate 1. The ejection mechanism 31 includes a component movably connected to the sampling cylinder 7. The sampling cylinder 7 has a connecting column 311, a connecting rod 312 fixedly connected to the top of the connecting column 311, a first spring 313 fixedly connected to the bottom of the connecting rod 312, an ejector plate 314 fixedly connected to the inner end of the connecting column 311, a snap-fit ​​hole on the upper part of the connecting rod 312, an mounting plate 315 fixedly connected to the upper part of the sampling cylinder 7, a snap-fit ​​rod 316 movably connected inside the mounting plate 315, a rotating rod 317 fixedly connected to the outer end of the snap-fit ​​rod 316, a second spring 318 fixedly connected to the inner side of the rotating rod 317, a positioning rod 319 fixedly connected to the inner side of the rotating rod 317, a positioning groove 3110 on one side of the mounting plate 315, and a positioning hole on the lower part of the mounting plate 315.

[0031] In this embodiment, the inner end of the connecting column 311 is fixedly connected to the ejector plate 314, the bottom end of the first spring 313 is fixedly connected to the sampling cylinder 7, the snap-fit ​​rod 316 is snapped into the connecting rod 312 through the snap-fit ​​hole, and one end of the second spring 318 is fixedly connected to the mounting plate 315. Through the cooperation of the connecting column 311, the connecting rod 312, the first spring 313, the ejector plate 314, the mounting plate 315, the snap-fit ​​rod 316, and the second spring 318, after the sampling cylinder 7 takes a sample, the snap-fit ​​rod 316 can be manually separated from the connecting rod 312, and the sample can be ejected outward by the ejector plate 314, which makes it easier to manually remove the sample.

[0032] Furthermore, the positioning rod 319 is snapped into the mounting plate 315 through the positioning hole. The positioning rod 319 is adapted to the positioning groove 3110. Through the cooperation of the positioning rod 319, the positioning groove 3110 and the rotating rod 317, the snapping rod 316 can be stopped at a position away from the mounting plate 315, thereby freeing up the operator's hands and making it easier for the operator to perform sampling operations.

[0033] Furthermore, there are four connecting columns 311, arranged in pairs and symmetrically distributed on the upper part of the sampling cylinder 7.

[0034] After the sampling tube 7 has finished sampling, manually hold the rotating rod 317 and pull the locking rod 316 outward to separate the locking rod 316 from the connecting rod 312. When the rotating rod 317 moves outward, the positioning rod 319 fixedly connected to the inner side of the rotating rod 317 can move outward, thereby separating the positioning rod 319 from the positioning hole. Then, manually rotate the rotating rod 317 and lock the positioning rod 319 into the positioning groove 3110, so that the locking rod 316 can stay in a position away from the connecting rod 312 without manual support of the rotating rod 317. Then, manually separate the locking rod 316 on the other side from the connecting rod 312. Then, under the action of the elastic force of the first spring 313, the ejector plate 314 fixedly connected to the inner end of the connecting column 311 can be ejected outward. The sample can then be ejected outward manually.

[0035] Example 2

[0036] Based on Example 1, a preferred embodiment of the shallow geothermal sample collection device provided by this utility model is as follows: Figures 1 to 4 As shown: The sampling mechanism 32 includes a motor 321 installed inside the fixed sleeve 5. A lead screw 322 is fixedly connected to the output end of the motor 321. An installation column 323 is fixedly connected to the inner wall of the fixed sleeve 5. A sliding groove 324 is opened on one side of the installation column 323. A sliding rod 325 is fixedly connected to the inner wall of the sliding groove 324. A slider 326 is slidably connected to the outer wall of the sliding rod 325. Insulation cotton 327 is fixedly sleeved on the outer wall of the fixed sleeve 5. A protective sleeve 328 is fixedly sleeved on the outer wall of the insulation cotton 327.

[0037] In this embodiment, the slider 326 is fixedly installed with the motor 321, the bottom end of the lead screw 322 is fixedly connected to the sampling cylinder 7, and the lead screw 322 is threadedly connected to the support plate 6. Through the cooperation of the lead screw 322, slider 326, slide bar 325, support plate 6, and sampling cylinder 7, it is convenient to perform manual sampling operations. At the same time, the anti-slip strip 8 can prevent the sample from falling. Through the cooperation of the insulation cotton 327 and the protective sleeve 328, the sample can be kept warm, thereby making the sample survey results more accurate.

[0038] When sampling is required, the motor 321 drives the lead screw 322 to rotate clockwise. Under the limiting action of the slider 326 and the slide bar 325, and because the lead screw 322 is threadedly connected to the support plate 6, the rotation of the lead screw 322 causes the sampling cylinder 7, which is fixedly connected to the bottom of the lead screw 322, to rotate downwards. Simultaneously, the sampling cylinder 7 can drill downwards to the ground surface to achieve the sampling operation. After drilling a certain distance, the motor 321 drives the lead screw 322 to rotate counterclockwise, which allows the sampling cylinder 7 to move upwards. With the help of the anti-slip strip 8, the sample can be taken out, making it difficult for the sample to fall off. At the same time, the heat insulation cotton 327 fitted on the outer surface of the fixed sleeve 5 can keep the inside of the fixed sleeve 5 warm, achieving the goal of keeping the sample warm, thereby making the survey results more accurate.
