Description

Technical Field

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

[0002] Petroleum is one of the main targets of geological exploration. It is a viscous, dark brown liquid, often referred to as the "blood of industry." Petroleum reserves exist in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons.

[0003] A search revealed that Chinese Patent Publication No. CN 220304870 U discloses a sampling device for oil exploration, comprising a drilling rig. The drilling rig has a hexagonal drive shaft at its bottom, a full-load warning mechanism at its bottom, a sampling cylinder at its bottom, a sampling drill bit at its bottom, and an extension drill bit at its bottom. The beneficial effects are: This invention forms a sampling cylinder by interlocking a first arc-shaped groove and a second arc-shaped groove during use. After sampling, the sample is removed by separating the first and second arc-shaped grooves, thus achieving the effect of retrieving a complete sample and preventing sample damage or confusion that could render it unsuitable for testing.

[0004] The exploration and sampling device in the aforementioned patent still has certain shortcomings. When conducting oil exploration, it is usually necessary to sample and monitor the rock strata underground for analysis. However, most existing exploration and sampling devices use a motor to drive the drill bit for drilling. The motor is mostly operated by hand, which has poor stability. Moreover, it is difficult to drill straight down during drilling and sampling, which makes sampling difficult. The motor with a frame is mostly fixed together and difficult to separate, which makes it difficult to carry when going out and is not convenient for users. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient field sampling device for oil exploration. It solves the problems of existing exploration sampling devices, most of which rely on electric motors to drive drill bits for drilling. However, electric motors are mostly operated manually by workers, resulting in poor stability and difficulty in drilling straight down during sampling. Furthermore, electric motors with frames are mostly fixed together and difficult to separate, making them difficult to carry and use by users.

[0006] This utility model provides the following technical solution: a convenient field sampling device for oil exploration, including a gasoline engine, a drill bit installed at the drive end at the bottom of the gasoline engine, two limiting blocks symmetrically arranged on both sides of the gasoline engine, and a sampling auxiliary component arranged on the outside of the gasoline engine;

[0007] The sampling auxiliary component includes two sets of support crossbars. The ends of the two support crossbars are fixedly connected by a fixed connecting post. Two adjustment holes are symmetrically opened at both ends of the support crossbars. The side walls of the adjustment holes are all provided with side wall insertion holes. A ground support rod is inserted into each adjustment hole. The side walls of the ground support rods are evenly provided with several abutment grooves. The ends of the fixed connecting posts are all provided with end retraction grooves. The top side wall of the end retraction groove is provided with a limiting sliding groove. A fixed rod is slidably inserted into the end retraction groove. A push-pull rod is vertically arranged on the top side of the end of the fixed rod. The top of the push-pull rod passes through the limiting sliding groove. A return spring is also provided in the end retraction groove.

[0008] Preferred technical solution 1: One end of the reset spring is connected to the fixed insertion rod, and the other end of the reset spring is connected to the inner wall of the end retraction groove.

[0009] Preferred technical solution 2: A fixed connecting plate is fixed to the side of the middle part of the supporting crossbar, and a movable sliding groove is opened on the side of the fixed connecting plate.

[0010] Preferred technical solution 3: The bottom end of the ground-inserting support rod is conical.

[0011] This solution makes it easier to insert the ground support rod into the ground.

[0012] Preferred technical solution four: The end of the fixing rod is inserted into the contact groove through the side wall insertion hole.

[0013] This design allows the contact groove on the side of the adjustable insertion hole to be fixed by the limiting position of the insertion rod.

[0014] Preferred technical solution five: The limiting block is slidably inserted into the movable groove.

[0015] This design allows the gasoline engine to be limited on both sides by sliding the limiting blocks into the moving groove, making the gasoline engine move more straight when it moves downwards.

[0016] Compared with existing technologies, this utility model provides a convenient field sampling device for oil exploration, which has the following advantages: This utility model sets a limiting block and a sampling auxiliary component on the side of the gasoline engine. The supporting crossbar and fixed connecting column in the sampling auxiliary component support the gasoline engine bracket. The bracket composed of the supporting crossbar and fixed connecting column is inserted into the ground on all four sides by ground-inserting support rods. The height of each ground-inserting support rod can be adjusted according to the terrain, providing more stable support for the gasoline engine. This allows the gasoline engine to slide into the moving groove through the limiting block, driving the drill bit to move more straight downwards, thereby drilling and sampling more complete rock core samples. The device can be disassembled and assembled as a whole, making it more convenient for users to carry outdoors and use for oil exploration sampling. Attached Figure Description

[0023] Please see Figure 1-4 ,

[0024] Example 1: A convenient field sampling device for oil exploration includes a gasoline engine 1, a drill bit 4 installed at the drive end of the bottom of the gasoline engine 1, two limiting blocks 2 symmetrically arranged on both sides of the gasoline engine 1, and a sampling auxiliary component 3 arranged on the outside of the gasoline engine 1.

[0025] The sampling auxiliary component 3 includes two sets of support crossbars 301. The ends of the two support crossbars 301 are fixedly connected by a fixed connecting post 302. Two adjustment holes 303 are symmetrically opened at both ends of the support crossbars 301. The side walls of the adjustment holes 303 are provided with side wall insertion holes 304. Ground support rods 305 are inserted into the adjustment holes 303. The side walls of the ground support rods 305 are evenly provided with several abutment grooves 306. The ends of the fixed connecting posts 302 are provided with end retraction grooves 307. The top side wall of the end retraction grooves 307 is provided with a limiting sliding groove 308. A fixed insertion rod 309 is slidably inserted into the end retraction grooves 307.

[0026] A push-pull rod 310 is vertically installed on the top side of the end of the fixed insertion rod 309. The top of the push-pull rod 310 passes through the limiting slide 308. A return spring 311 is also installed in the end retraction groove 307. One end of the return spring 311 is connected to the fixed insertion rod 309, and the other end of the return spring 311 is connected to the inner wall of the end retraction groove 307. A fixed connecting plate 312 is fixed on the side of the middle part of the support crossbar 301. A movable slide groove 313 is opened on the side of the fixed connecting plate 312.

[0027] Example 2: The difference between this example and Example 1 is that the bottom end of the ground support rod 305 is cone-shaped.

[0028] This makes it easier to insert the 305 ground support rod into the ground.

[0029] Example 3: The difference between this example and Example 1 is that the end of the fixed insertion rod 309 is inserted into the contact groove 306 through the side wall insertion hole 304.

[0030] This allows the contact groove 306 on the side of the insertion support rod 305, which is active through the adjustment socket 303, to be fixed by the limiting position of the fixing rod 309.

[0031] Example 4: The difference between this example and Example 1 is that the limiting block 2 is slidably inserted into the movable groove 313.

[0032] This allows the two sides of the gasoline engine 1 to be limited by the limit blocks 2, which are slidably inserted into the moving groove 313, making the gasoline engine 1 move more straight when it moves downward.

[0033] In this embodiment, since most existing exploration and sampling devices use a motor to drive the drill bit for drilling, and the motor is mostly operated by the worker by hand, the stability is poor, and it is difficult to drill straight down during drilling and sampling, which causes certain sampling difficulties. The motor with a frame is mostly fixedly installed with the other two, making it difficult to separate them, which will cause difficulties in carrying them when going out and is not convenient for users to use.

[0034] In summary, in practical implementation, when users need to conduct outdoor oil exploration sampling, since the gasoline engine 1 and the sampling auxiliary component 3 are separate from each other, and each structure of the sampling auxiliary component 3 is detachable, it makes it more convenient for users to disassemble and carry the device.

[0035] Once the user reaches the designated sampling location, the user can insert the ground support rod 305 from the sampling auxiliary component 3 into the adjustment socket 303. The support crossbar 301 and the fixed connecting column 302 form the top support. By pulling the push-pull rod 310, the user can cause the fixed insertion rod 309 to retract into the end retraction groove 307. The user can then adjust the length of the ground support rod 305 inserted into the adjustment socket 303, and the length adjustment of each ground support rod 305 can be performed separately.

[0036] It is more suitable for various complex terrains, so that the bracket composed of the support crossbar 301 and the fixed connecting column 302 can always be adjusted to a horizontal state. When the length of each ground support rod 305 is appropriately adjusted, the fixed rod 309 is pushed by the return force of the return spring 311 to pass through the side wall insertion hole 304 and be inserted into the contact groove 306, thereby fixing the ground support rod 305 and the support crossbar 301.

[0037] Next, the user slides the limiting blocks 2 on both sides of the gasoline engine 1 into the moving slide 313, so that the descent of the gasoline engine 1 is limited by the moving slide 313, which drives the drill bit 4 to drill and sample more straight, making it easier to obtain complete sample rock cores and making the operation more convenient.
