Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a soil sampling device for oil exploration. Background Technology

[0002] Soil sampling plays a crucial role in oil exploration. Analyzing soil samples, including their organic matter content and mineral composition, provides vital information about reservoir characteristics, such as oil type and oil content. Besides deep sampling, shallow soil sampling is equally important in oil exploration. Compared to deep soil sampling, shallow soil sampling, as a rapid, economical, and safe exploration method, can reveal the geological structure, surface environment, and soil types of the study area. This is crucial for the selection of oil exploration areas and the planning of subsequent work (such as assessing the potential environmental impacts of oil extraction activities, including post-extraction soil pollution risk assessment).

[0003] In the prior art, such as the soil sampling device for high-standard farmland construction described in Chinese Patent No. CN222652615U, a mobile cart is included. A sampling mechanism is set on one side of the top of the mobile cart, and two sampling tubes are placed on the top of the mobile cart. A cleaning and rust prevention mechanism is set on the other side of the top of the mobile cart. Through the cleaning and rust prevention mechanism, the user starts the motor, which drives the lead screw to make the moving support slide back and forth. As the moving support slides back and forth, the connecting rod on the front of the moving support drives two cleaning scrapers to scrape off the soil on the inner wall of the sampling tube. Cleaning the inner wall of the sampling tube can reduce the residue inside the sampling tube and avoid reducing the accuracy of the test results due to the residue inside the tube during the next sampling. At the same time, as the moving support slides, the rust removal liquid inside the storage box can be transported to the relay box through the transmission pipe and sprayed out from multiple nozzles, which can prevent the sampling tube from rusting, ensure the purity of the sampling results, and extend the service life of the sampling tube.

[0004] While the aforementioned patent can sample soil, it still has some problems. When the sampling tube is sampling soil, it will experience high-intensity friction with the soil surface, which will cause the surface temperature of the sampling tube to become too high. This may result in burns when contacting the sampling tube later. Therefore, this utility model provides a soil sampling device for oil exploration. Utility Model Content

[0012] Beneficial effects This invention provides a soil sampling device for oil exploration. Compared with the prior art, it has the following advantages: 1. This soil sampling device for oil exploration, when sampling is completed and the sampling tube begins to rise, triggers the first motor to start, driving the threaded screw to rotate within the first housing. The first movable slider, threadedly connected to the screw, moves upward along the screw. The driving wheel at the bottom of the threaded screw drives the driven wheel via a belt, thereby causing the first rotating rod to rotate at high speed. The first rotating rod meshes with the second bevel gear on the second rotating rod via a first bevel gear, driving the second rotating rod to rotate, causing the fan blades mounted at its other end to rotate, generating strong airflow. The driving wheel's diameter is larger than that of the driven wheel, forming a speed-increasing transmission that further increases the fan blade speed and enhances the air-cooling effect. 2. This soil sampling device for oil exploration, when the fan blades are activated, continuously sprays water through the coordinated action of a water pump and water tank, ensuring that the water mist always covers the surface of the sampling tube. The wind force evenly disperses the water mist, and through a combination of water vapor evaporation and heat absorption and air cooling, the high temperature generated by friction in the sampling tube is quickly reduced, thus preventing the risk of burns when removing soil from the sampling tube.

[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] This utility model provides two technical solutions: Figures 1-5 The first embodiment is shown: a soil sampling device for oil exploration, including a movable plate 1, a through groove 2 is provided at the top of the movable plate 1, a sampling motor 6 and a sampling tube 7 are provided above the through groove 2, and a cooling component 3 and a spraying component 4 are respectively provided at the top of the movable plate 1. The cooling assembly 3 includes a first housing 31 and a first mounting bracket 35. A threaded screw 32 is rotatably mounted on the inner wall of the first housing 31. The bottom end of the threaded screw 32 passes through the inner wall of the first mounting bracket 35 and is fixedly mounted with a drive wheel 36. Two first rotating rods 39 are rotatably mounted on the top of the first mounting bracket 35. Driven wheels 37 are fixedly mounted on the bottom ends of the two first rotating rods 39. Two belts 38 are respectively sleeved between the two driven wheels 37 and the drive wheel 36. When the threaded screw 32 rotates, it can drive the drive wheel 36 to rotate, and then drive the two driven wheels 37 to rotate through the belts 38. A set of rotatable fan blades 314 are respectively provided at the top of the two first rotating rods 39. The spray assembly 4 includes a second mounting bracket 44, on the inner wall of which a spray pipe 45 is fixedly mounted.

[0021] The first housing 31 is fixedly installed on the top of the first mounting bracket 35. The outer wall of the threaded screw 32 is threadedly connected to the first movable slider 33. The top of the first housing 31 is fixedly installed with the first motor 34. The output shaft of the first motor 34 passes through the inner wall of the first housing 31 and is fixedly connected to the top of the threaded screw 32. The first motor 34 can drive the threaded screw 32 to rotate. During the rotation of the threaded screw 32, the first movable slider 33 can be moved.

[0022] Two vertical plates 312 are fixedly installed at the top of the first mounting bracket 35. A second rotating rod 313 is rotatably installed on the outer wall of the vertical plate 312. A second bevel gear 311 is fixedly installed at one end of the outer wall of the second rotating rod 313. A first bevel gear 310 is fixedly installed at one end of the outer wall of the first rotating rod 39. The second bevel gear 311 and the first bevel gear 310 are meshed. The other end of the outer wall of the second rotating rod 313 is fixedly connected to a set of fan blades 314. When the first rotating rod 39 rotates, the fan blades 314 can be driven to rotate through the mutual cooperation of the two bevel gears.

[0023] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the outer diameter of the driving wheel 36 is larger than that of the driven wheel 37, which can increase the rotation speed of the driven wheel 37. The top of the second mounting bracket 44 is fixedly mounted with a second housing 41. The inner wall of the second housing 41 is fixedly mounted with a slide rod 42. The outer wall of the slide rod 42 is slidably connected with a second movable slider 43. A lifting plate 5 is fixedly mounted between the opposite sides of the first movable slider 33 and the second movable slider 43. The sampling motor 6 is fixedly mounted on the top of the lifting plate 5. The output end of the sampling motor 6 passes through the bottom end of the lifting plate 5 and is fixedly connected to the sampling tube 7. The sampling motor 6 can drive the sampling tube 7 to rotate, and then, driven by the lifting plate 5, it can collect soil samples from below.

[0024] A water pump 48 and a water tank 49 are fixedly installed on the top of the movable plate 1. The water pump 48 and the water tank 49 are fixedly connected. The output end of the water pump 48 is fixedly connected to a connecting pipe 47. The output end of the connecting pipe 47 passes through the top of the second mounting bracket 44 and is fixedly connected to the spray pipe 45. A set of atomizing nozzles 46 are provided on the outer wall of the spray pipe 45. When the water pump 48 is started, it can draw water from the water tank 49 into the spray pipe 45, and then spray the water out through the atomizing nozzles 46.

[0025] A battery 8 is fixedly installed at the top of the movable plate 1, a push rod 9 is fixedly installed on the outer wall of the movable plate 1, and four casters 10 are fixedly installed at the bottom of the movable plate 1. The first mounting bracket 35 and the second mounting bracket 44 are both fixedly connected to the movable plate 1.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, the operator moves the soil sampling device to the target oil exploration area using the push rod 9 and casters 10, with the battery 8 providing power. When soil sampling is required, the first motor 34 is started, and its output shaft drives the threaded screw 32 to rotate within the first housing 31. Since the first movable slider 33 is threadedly connected to the threaded screw 32, it moves downwards along the screw due to the threaded transmission as the screw rotates. Because the sampling motor 6 is fixedly mounted on the lifting plate 5, the descent of the first movable slider 33 causes the lifting plate 5, the sampling motor 6, and the sampling tube 7 to move downwards synchronously. Simultaneously, the output shaft of the sampling motor 6 drives the sampling tube 7 to rotate at high speed, ensuring that the sampling tube 7 is inserted vertically into the soil at a stable speed, guaranteeing the stability and accuracy of the insertion process.

[0028] Once sampling is complete, the sampling tube 7 needs to rise to remove the sampled soil. The first motor 34 starts, driving the threaded screw 32 to rotate within the first housing 31. The first movable slider 33, threadedly connected to the screw, moves upward along the screw. The driving wheel 36 at the bottom of the threaded screw 32 drives the driven wheel 37 via the belt 38, which in turn causes the first rotating rod 39 to rotate at high speed. The first rotating rod 39 meshes with the second bevel gear 311 on the second rotating rod 313 via the first bevel gear 310, driving the second rotating rod 313 to rotate, causing the fan blade 314 mounted at its other end to rotate, generating strong wind. The driving wheel 36, with a larger diameter than the driven wheel 37, forms a speed-increasing transmission, further increasing the speed of the fan blade 314 and enhancing the air-cooling effect. Simultaneously with the fan blade 314 starting, the spray pipe 45 continuously sprays mist. The wind force evenly disperses the water mist, and through the combination of water vapor evaporation heat absorption and air cooling, the high temperature generated by friction in the sampling tube 7 is quickly reduced, thus preventing the risk of burns when removing soil from the sampling tube 7.
