[0001] This utility model relates to the field of oilfield development technology, specifically to a geological exploration and sampling device for oilfield development. Background Technology
[0002] An oil field refers to the total amount of oil and gas reservoirs within the same oil and gas producing area under the control of a single geological structure (or stratum) factor. Before the development of an oil field, it is necessary to use sampling devices to investigate the geological and soil conditions of the area to be developed.
[0003] Patent CN218600899U discloses a geological exploration sampling device for oilfield development, including a box body. A fixing plate is fixedly connected to the top of the outer surface of the box body, and a support plate is fixedly connected to the edge of the lower surface of the fixing plate.
[0004] While existing technologies have achieved the goal of continuously collecting soil samples from different depths, they lack a stable mechanism and cannot provide stable support for the sampling device during sampling operations, thus affecting the stable operation of the sampling process.
[0005] To address the aforementioned problems, this application proposes a geological exploration and sampling device for oilfield development. Utility Model Content
[0006] In order to solve the problem that existing technologies cannot provide stable limiting support for the sampling device during sampling operations, the purpose of this utility model is to provide a geological exploration sampling device for oilfield development.
[0007] To solve the above technical problems, the present invention adopts the following technical solution: a geological exploration sampling device for oilfield development, including a base plate, a box body fixedly installed on one side of the top of the base plate, and a sampling mechanism for use on one side of the box body, universal wheels fixedly installed at the four corners of the bottom of the base plate, and a stabilizing mechanism for use with the universal wheels on the base plate, and a fixing mechanism for use with the stabilizing mechanism.
[0008] The stabilizing mechanism includes a U-shaped plate and side plates, both of which are fixedly mounted on the base plate. The U-shaped plate has a symmetrical structure. A motor is fixedly mounted at the top of the U-shaped plate, and the output end of the motor rotates through the U-shaped plate and is fixedly fitted with an L-shaped plate at its end. An electric push rod is fixedly inserted into the end of the L-shaped plate, and a sleeve is fixedly connected to the output end of the electric push rod. A plug is detachably inserted into the sleeve, and a base plate is fixedly mounted at the bottom of the plug. An insert block is integrally formed on the plug, and the insert block can slide into the sleeve. A slot is opened through the sleeve, and the insert block can slide into the slot. The outer diameter of the insert block is the same as the inner diameter of the slot. A matching conical rod is fixedly connected to the bottom of the base plate. A symmetrically arranged arc-shaped cover is fixedly mounted on the end of the base plate near the sampling mechanism, and the conical rod can be movably inserted into the arc-shaped cover. An electric push rod is fixedly inserted into the side plate, and a matching support plate is fixedly connected to the output end of the electric push rod.
[0009] Preferably, the fixing mechanism includes a rod that is slidably inserted into a sleeve, and a pull ring is fixedly sleeved at the end of the rod. A sliding hole is provided through the sleeve, and the rod is slidably inserted into the sliding hole. A matching groove is provided on the outer wall of the pull ring, and the groove has a symmetrical structure.

[0020] 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.
[0021] Example: Figures 1-5 As shown, this utility model provides a geological exploration sampling device for oilfield development, including a base plate 1, a box 2 fixedly installed on one side of the top of the base plate 1, and a sampling mechanism 3 for use on one side of the box 2. A placement rack is provided inside the box 2, and the sampling mechanism 3 can perform soil sampling operations. These are all existing technologies and will not be described in detail here. Universal wheels 4 are fixedly installed at the four corners of the bottom of the base plate 1, and a stabilizing mechanism 5 for use with the universal wheels 4 is provided on the base plate 1. A fixing mechanism 6 for use is provided on the stabilizing mechanism 5.
[0022] The stabilizing mechanism 5 includes a U-shaped plate 51 and a side plate 52, both of which are fixedly mounted on the base plate 1. The U-shaped plate 51 has a symmetrical structure. A motor 53 is fixedly mounted at the top of the U-shaped plate 51, and the output end of the motor 53 rotates through the U-shaped plate 51 and is fixedly fitted with an L-shaped plate 54 at its end. An electric push rod 55 is fixedly inserted into the end of the L-shaped plate 54, and a sleeve 56 is fixedly connected to the output end of the electric push rod 55. A post 57 is detachably inserted into the sleeve 56, and a base plate 58 is fixedly mounted at the bottom end of the post 57. A block 515 is integrally formed on the post 57, and the block 515 can slide onto the sleeve 56. A slot 516 is provided through the cylinder 56, and the insert 515 can be slidably inserted into the slot 516. The outer diameter of the insert 515 is the same as the inner diameter of the slot 516. The cooperation between the insert 515 and the slot 516 ensures the accurate and stable insertion of the insert 57 and the sleeve 56. A matching cone rod 59 is fixedly connected to the bottom end of the chassis 58. A symmetrically arranged arc-shaped cover 514 is fixedly installed on the end of the base plate 1 near the sampling mechanism 3, and the cone rod 59 can be movably inserted into the arc-shaped cover 514. An electric push rod 510 is fixedly inserted into the side plate 52, and a matching support plate 511 is fixedly connected to the output end of the electric push rod 510.
[0023] By adopting the above technical solution, when in use, the two motors 53 are started, which can drive the two L-shaped plates 54 to rotate synchronously to both sides of the base plate 1. After the L-shaped plates 54 rotate 90 degrees, the motors 53 are turned off. Then, the electric push rod 1 55 and the electric push rod 2 510 will be started synchronously, which can drive the sleeve 56 and the support plate 511 to move down. Then, the cone rod 59 can be driven down through the insertion post 57 and the base plate 58 until the cone rod 59 is inserted into the soil at a suitable depth and the support plate 511 is in close contact with the ground. Then, the electric push rod 1 55 and the electric push rod 2 510 are turned off. After that, the sampling mechanism 3 can be used to carry out soil sampling. After the sampling is completed, the cone rod 59 and the support plate 511 can be reset.
[0024] The fixing mechanism 6 includes a rod 61, which is slidably inserted into the sleeve 56. A pull ring 62 is fixedly sleeved at the end of the rod 61. A sliding hole 513 is provided through the sleeve 56, and the rod 61 is slidably inserted into the sliding hole 513. The sliding hole 513 ensures the stable insertion of the rod 61. A groove 64 is provided on the outer wall of the pull ring 62, and the groove 64 has a symmetrical structure. The groove 64 can increase friction and facilitate operation. A spring 63 is fixedly installed on one side of the pull ring 62, and the end of the spring 63 is fixedly connected to the sleeve 56. A insertion hole 512 is provided on the insertion post 57, and the rod 61 can be slidably inserted into the insertion hole 512.
[0025] By adopting the above technical solution, when the cone rod 59 is outside the arc-shaped cover 514, the pull ring 62 can be pulled away from the sleeve 56, thereby driving the corresponding insertion rod 61 to move and stretching the corresponding spring 63. When the distance between the pull ring 62 and the corresponding sleeve 56 is moved to the maximum, the insertion rod 61 will be completely separated from the corresponding insertion hole 512. At this time, the corresponding cone rod 59, the base 58 and the insertion post 57 can be moved down and the corresponding insertion post 57 can be completely separated from the corresponding sleeve 56. Then, hold the base 58 corresponding to another new cone rod 59 and insert the corresponding insertion post 57 into the sleeve 56. After that, release the corresponding pull ring 62. At this time, the spring 63 will drive the corresponding insertion rod 61 to reset and insert it into another corresponding insertion hole 512.
[0026] Working principle: When in use, push the sampling device to a suitable position, then start the two motors 53, which can drive the two L-shaped plates 54 to rotate synchronously to both sides of the base plate 1. After the L-shaped plates 54 rotate 90 degrees, turn off the motors 53. Then, the electric push rod 1 55 and the electric push rod 2 510 will start synchronously, which can drive the sleeve 56 and the support plate 511 to move down. Then, the cone rod 59 can be driven down through the insertion post 57 and the base plate 58 until the cone rod 59 is inserted into the soil at a suitable depth and the support plate 511 is in close contact with the ground. Then, turn off the electric push rod 1 55 and the electric push rod 2 510. After that, the sampling mechanism 3 can be used to carry out soil sampling. After the sampling is completed, the cone rod 59 and the support plate 511 can be reset.
[0027] Furthermore, during subsequent use, when the cone rod 59 is outside the arc-shaped cover 514, the pull ring 62 can be pulled away from the sleeve 56, thereby moving the corresponding insertion rod 61 and stretching the corresponding spring 63. When the gap between the pull ring 62 and the corresponding sleeve 56 is moved to the maximum, the insertion rod 61 will be completely separated from the corresponding insertion hole 512. At this time, the corresponding cone rod 59, the base 58 and the insertion post 57 can be moved down and the corresponding insertion post 57 can be completely separated from the corresponding sleeve 56. Then, hold the base 58 corresponding to another new cone rod 59 and insert the corresponding insertion post 57 into the sleeve 56. After that, release the corresponding pull ring 62. At this time, the spring 63 will drive the corresponding insertion rod 61 to reset and insert it into another corresponding insertion hole 512.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
