Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration equipment, and particularly to a geological sampling device for electric power construction. Background Technique

[0002] Before electric power construction, geological exploration and sampling detection are extremely important. Different geological conditions determine the types of foundations for electric power infrastructure such as substations and transmission towers. Through geological exploration and sampling, it is possible to accurately determine whether the underground is rock, sand, clay, or other special soil types. For example, if it is a soft soil foundation, pile foundations may be required to transfer the load of the building to deeper and stronger bearing soil layers; while on a rock foundation, only simple shallow foundations may be needed. Accurate geological sampling detection provides a key basis for the reasonable selection of foundation types, avoiding problems such as settlement or inclination of electric power facilities caused by inappropriate foundation types.

[0003] A Chinese patent with the publication number CN211477702U discloses a sampling device for geological exploration, including a support plate, a fixing mechanism, support columns, a lifting mechanism, and a through hole. Fixing mechanisms are provided at the bottom ends on both sides of the support plate. A through hole is provided at the central position of the support plate. Support columns are fixedly connected to both sides of the top end of the support plate, and a lifting mechanism is provided inside the support columns. A buffer mechanism is fixedly connected to the top end of the lifting mechanism. Inside the buffer mechanism, there are sequentially arranged a housing, an inner cavity, a moving groove, a hinge block, and a spring. A moving groove is provided at the central position on one side of the housing. An inner cavity is provided inside the housing. A cross plate is provided above the support plate.

[0004] To sum up, the above patent drives the rotation of the rotating shaft and the sampling blade through a motor, so as to enter the ground, and the sampling blade brings the soil into the storage cylinder to achieve soil sampling. However, in this sampling method, due to the rotation and drilling actions of the drill bit, it will disturb the surrounding geological samples, which will cause the soil samples at different depths to mix with each other. Such a mixed sample will interfere with the accurate judgment of the geological characteristics of each layer, resulting in deviation in geological analysis. Summary of the Invention

[0005] The purpose of the present invention is to provide a geological sampling device for electric power construction to solve the problem that in the sampling method of the above patent, due to the rotation and drilling actions of the drill bit, it will disturb the surrounding geological samples, which will cause the soil samples at different depths to mix with each other as mentioned in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A geological sampling device for electric power construction, including a main body,

[0007] One end of the bottom of the main body is provided with a sampling hole, and a number of groups of casters are arranged at the bottom of the main body. A T-shaped frame is vertically arranged inside the main body, and an L-shaped movable frame one and an L-shaped movable frame two are respectively arranged on both sides of the T-shaped frame. A drilling mechanism is arranged on the L-shaped movable frame one, and a sampling mechanism is arranged on the L-shaped movable frame two;

[0008] The sampling mechanism includes a second motor. The second motor is installed on the top of the L-shaped movable frame two, and a rotating shaft is arranged at the output end of the second motor. A collecting cylinder is arranged below the rotating shaft, and a vertical rod is arranged at the midpoint inside the collecting cylinder. A notch is arranged on the side of the collecting cylinder. A number of groups of partition plates one are fixed on the vertical rod, and a soil cutting plate is fixed on the outside of the collecting cylinder;

[0009] Two vertical moving mechanisms are also arranged on both sides of the L-shaped movable frame two. The two vertical moving mechanisms are used to drive the L-shaped movable frame one and the L-shaped movable frame two to move vertically respectively;

[0010] A fourth motor is fixed on the top of the main body, and the output end of the fourth motor is connected to the midpoint of the T-shaped frame. Support mechanisms are arranged at both ends of the outside of the main body.

[0011] In the above technical solution, the second motor drives the rotating shaft and the collecting cylinder to rotate clockwise. The soil cutting plate on the side of the collecting cylinder will cut and guide the soil on the inner wall of the drilling hole. The cut soil will enter the inside of the collecting cylinder through the notch on the side of the collecting cylinder. And because a number of groups of partition plates one are arranged inside the collecting cylinder, each partition layer can isolate samples at different depths, reducing cross-contamination between samples and making the geological analysis results more reliable.

[0012] Preferably, the drilling mechanism includes a first motor. The first motor is installed on the top of the L-shaped movable frame one, and a drill rod is arranged at the output end of the first motor.

[0013] In the above technical solution, the first motor drives the drill rod to rotate, and the vertical moving mechanism drives the L-shaped movable frame one and the drill rod to descend, so that the drill rod can penetrate the sampling hole for drilling operation.

[0014] Preferably, a fixing plate is fixed on the outside of the collecting cylinder, and a number of groups of soil breaking cones are fixed on the side of the fixing plate.

[0015] In the above technical solution, a fixing plate and soil breaking cones are arranged on the side of the collecting cylinder. When the collecting cylinder rotates clockwise, the soil breaking cones will break the soil on the inner wall of the drilling hole first. The setting of the soil breaking cones enhances the adaptability of the device to different soil qualities. When encountering harder soil layers or soil containing hard lumps, the soil breaking cones can break the soil in advance, making it easier for the soil to enter the collection cylinder. Whether it is clay, sandy soil, or soil containing a small amount of gravel, it can ensure a good sampling effect and ensure that complete samples are collected.

[0016] Preferably, the vertical movement mechanism includes a third motor, which is installed at both ends of the top of the T-shaped frame. A lead screw is provided at the output end of the third motor. There are two sets of the third motor and the lead screw, and the two lead screws respectively penetrate through the first L-shaped movable frame and the second L-shaped movable frame and are threadedly connected thereto.

[0017] In the above technical solution, the two third motors can drive the two lead screws to rotate, and the two lead screws can respectively drive the first L-shaped movable frame and the second L-shaped movable frame threadedly connected thereto to move vertically.

[0018] Preferably, a number of second partitions are fixed on the first partition. A fixing ring is fixed on the top of the collection cylinder, and the top of the fixing ring is fixedly connected to a rotating shaft through a U-shaped frame. A rotating rod is arranged inside the fixing ring, and the rotating rod is connected to a vertical rod. A gear is fixed on the rotating rod, and a handwheel is fixed on the top of the rotating rod. A limiting mechanism is arranged on the side of the fixing ring.

[0019] In the above technical solution, by arranging a plurality of second partitions on the first partition for partitioning, when the A area on the first partition collects soil, the handwheel can be rotated to drive the rotating rod and the vertical rod to rotate, and the vertical rod will drive the first partition to rotate, so that the B area on the first partition can be rotated to the sampling position aligned with the notch. Then, the vertical rod can be locked by the limiting mechanism, so that the soil in different areas can be isolated and stored. Since accurate stratification and area division can be achieved, it is very convenient to compare between samples in different areas, improving the efficiency of the entire geological sampling and research work.

[0020] Preferably, the limiting mechanism includes a plug rod, which penetrates through the side of the fixing ring. A pull ring is fixed on the outside of the plug rod. A spring is sleeved on the plug rod, and the two ends of the spring are respectively connected to the outer wall of the fixing ring and the pull ring.

[0021] In the above technical solution, by pulling the pull ring to drive one end of the plug rod out of the tooth groove of the gear, the gear and the rotating rod can be unlocked, so as to conveniently rotate the handwheel to drive the rotating rod, the vertical rod and the first partition to rotate for partitioning and storing the soil. After rotation, the pull ring can be released. At this time, the spring will drive the pull ring and the plug rod to reset, and the plug rod will insert into the tooth groove of the gear to lock the gear, the rotating rod, the vertical rod and the first partition.

[0022] Preferably, the support mechanism includes a support frame, which is fixed at both ends of the side of the main body. A screw rod is threadedly connected inside the support frame, and a support leg is installed at the bottom of the screw rod.

[0023] In the above technical solution, by rotating the screw rod to drive the support leg to descend, the main body can be supported during the sampling drilling process to improve the stability of the main body. It is also possible to adjust the descending positions of the two support legs in an uneven area to conveniently adjust the main body to a vertical state for drilling.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: for the geological sampling device for electric power construction,

[0025] (1) After the drilling mechanism penetrates the sampling hole at the bottom of the main body to drill the target area, the T-shaped frame can be rotated by the motor four to exchange the positions of the drilling mechanism and the sampling mechanism. Then, the vertical movement mechanism drives the collection cylinder to descend into the drill hole. The motor two drives the rotating shaft and the collection cylinder to rotate clockwise. The soil cutting plates on the side of the collection cylinder will cut and divert the soil on the inner wall of the drill hole, and the cut soil will enter the interior of the collection cylinder through the notch on the side of the collection cylinder. Since several groups of partition plates one are arranged inside the collection cylinder, each compartment can isolate samples at different depths. During the collection process, this can ensure that the samples in each compartment can truly reflect the geological characteristics of their corresponding depths, reduce cross-contamination between samples, and make the geological analysis results more reliable;

[0026] (2) Since during the geological sampling process, it is necessary to collect soils in different areas. In the comparison case, the sampling mechanism needs to be cleaned after collecting the soil before collecting the soil at the next position. By arranging multiple partition plates two on the partition plate one for zoning, when the soil is collected in area A on the partition plate one, the rotating handwheel can be rotated to drive the rotating rod and the vertical rod to rotate, and the vertical rod will drive the partition plate one to rotate, so that area B on the partition plate one can be rotated to the sampling position aligned with the notch. Then, the vertical rod is locked by the limiting mechanism, so that the soils in different areas can be isolated and stored. Compared with the comparison case, there is no need to clean the partition plate one after one collection. And because accurate stratification and area division can be achieved, when performing data analysis, it is very convenient to compare between samples in different areas, which greatly facilitates the subsequent laboratory analysis and data sorting work, reduces analysis errors caused by sample confusion, and improves the efficiency of the entire geological sampling and research work.

[0044] Working principle: When in use, after moving the main body 1 to the sampling position through the casters 2 at the bottom of the main body 1, the rotatable screw rod 2202 can drive the support leg 2203 to descend to support the main body 1, improving the stability of the main body 1. Then, the motor one 601 on the L-shaped movable frame one 4 can be turned on to drive the drill rod 602 to rotate, and the motor three 1401 located above the drill rod 602 can be turned on to drive the lead screw 1402 to rotate, so that the lead screw 1402 drives the L-shaped movable frame one 4 and the drill rod 602 to descend.
