Description

Technical Field

[0001] The utility model relates to the technical field of core sampling, in particular to an engineering geological survey device. Background Art

[0002] In the process of engineering geological survey, core sampling is an important means of obtaining information on the structure and material composition of underground rock formations. Traditional core sampling equipment often has some problems during operation, such as unstable fixation of the sampling tube leading to inaccurate sampling, difficulty in smoothly removing core samples, and susceptibility to external contamination during sample processing. In addition, in a field survey environment, the stability and convenience of the equipment have extremely high requirements for sampling efficiency and accuracy. Existing sampling devices are difficult to meet these requirements, especially in the sampling link after core sampling. The lack of an effective impact or vibration structure often makes it difficult to remove the core sample, increasing the complexity of the operation and the risk of damage to the sample. Therefore, in response to the above problems, it is of great significance to develop a geological survey device that can improve sampling accuracy, ensure smooth sample recovery and reduce pollution.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4The utility model provides a technical solution: an engineering geological survey device, comprising: a placement seat 1, a fixing assembly 3, a collecting plate 4 and a discharging assembly 5. The top of the placement seat 1 is provided with an inclined placement surface; the fixing assembly 3 is arranged in the end portion of the lower end of the placement seat 1, and the fixing assembly 3 is used to support and maintain the position of the sampling tube 6; the discharging assembly 5 is arranged on the fixing assembly 3 and can contact the outer wall of the sampling tube 6; the discharging assembly 5 is used to ensure that the core is smoothly taken out; the collecting plate 4 is overlapped at the lower end of the placement surface and is located on the outside of the sampling tube 6, and is used to collect the core sample released from the sampling tube 6.

[0023] The engineering geological survey device provided by this application is used for subsequent sampling in the core sampling link to ensure the accurate collection and smooth recovery of core samples in field surveys. The inclined placement surface of the placement seat 1 allows the sampling tube 6 to be placed in an inclined state, ensuring the smoothness of the entire sampling process. The fixing assembly 3 is located at the lower end of the placement seat 1, for supporting and fixing the sampling tube 6, ensuring that the sampling tube 6 can maintain a sampling position at a height suspended during the sampling process, making it easy to remove the material. The discharge assembly 5 contacts the outer wall of the sampling tube 6 and plays an auxiliary role, ensuring that the core sample can be smoothly removed from the sampling tube 6, avoiding blockage or damage to the sampling tube 6 during the sampling process. The collecting plate 4 is arranged at the outer position of the lower end of the placement surface, for receiving and collecting the core sample released from the sampling tube 6, ensuring that the sample is not contaminated and convenient for subsequent processing. Therefore, this device not only improves the accuracy and efficiency of sampling, but also greatly reduces the damage and external contamination of the core sample, and enhances the reliability of geological data.

[0024] In some examples, further, the fixing assembly 3 includes: a drawing rod 31, a handle 32, two moving blocks 33, two vertical rods 34 and a limiting abutment rod 35. The drawing rod 31 is rotatable around its own axis and is arranged in the inner cavity of the placement seat 1, and the thread directions of the two ends of the drawing rod 31 are opposite; the handle 32 is connected to the drawing rod 31, and the handle 32 is placed on the outside of the outer wall of the placement seat 1; the two moving blocks 33 are respectively threaded and sleeved on the two ends of the outer wall of the drawing rod 31 and can move relative to each other; the two vertical rods 34 are respectively fixed on each moving block 33, and the vertical rod 34 is located on the outside of the placement seat 1; the limiting abutment rod 35 is arranged on the inner side of the vertical rod 34 in an inclined state, and abuts against the bottom end of the sampling tube 6.

[0025] In this example, the fixing assembly 3 ensures the stable fixation and precise positioning of the sampling tube 6. Specifically, the drawing rod 31 is installed in the inner cavity of the placement seat 1. The threads at its two ends are in opposite directions, which means that when it is rotated, it can drive the two moving blocks 33 to move in opposite directions, thereby achieving the fixing or loosening operation. The handle 32 is connected to the outside of the drawing rod 31. The operator drives the drawing rod 31 to rotate by rotating the handle 32, thereby controlling the relative movement of the moving blocks 33. Each moving block 33 is fixed with a vertical rod 34. The vertical rod 34 is located outside the placement seat 1 and serves as a support and guide. When the two moving blocks 33 move, the vertical rod 34 also moves, ensuring that the fixing assembly 3 and the sampling tube 6 maintain the same spacing and position. The limiting abutment rod 35 is in an inclined state and is located on the inside of the vertical rod 34, directly abutting the bottom end of the sampling tube 6. This structure ensures that the sampling tube 6 is firmly positioned. This effectively solves the problem of unstable position and easy deviation of the sampling tube 6 during operation, ensuring sampling accuracy and sample quality.

[0026] In some examples, further, at least two support rods 2 are provided on the top end surface of the placement seat 1 , the top ends of the support rods 2 are arc-shaped, and the sampling tube 6 is fixedly supported above the placement seat 1 by multiple support rods 2 .

[0027] Specifically, the support rods 2 at the top of the mounting base 1 provide additional stabilizing support, reducing friction and vibration damage to the sampling tube 6 on the mounting base 1. The top of each support rod 2 is curved, enabling close contact with the outer wall of the sampling tube 6, making the sampling tube 6 more stable during installation and less likely to slip or deflect.

[0028] In some examples, further, the discharging assembly 5 includes: two lifting rods 51, a limiting column 52, a connecting piece 53, a pressing plate 54 and a vibration part 55. The two lifting rods 51 can be moved up and down and inserted into the inner cavity of the upper end of the corresponding vertical rod 34; the limiting column 52 is fixedly arranged on the inner wall surface of the two lifting rods 51; the connecting piece 53 can be movably mounted on the outer side of the outer wall of the two limiting columns 52; the pressing plate 54 is fastened to the outer wall of the sampling tube 6; a through hole is opened in the pressing plate 54; the vibration part 55 is arranged on the pressing plate 54 to provide impact to the sampling tube 6.

[0029] In this example, the discharge assembly 5 can help the core sample in the sampling tube 6 to be taken out smoothly, and provide the necessary impact force through vibration. Specifically, the two lifting rods 51 can move up and down in the inner cavity at the upper end of the vertical rod 34, allowing the height of the buckling plate 54 to be adjusted to accommodate sampling tubes 6 of different sizes, or to be used in the process of sampling tube 6 entering or removing. The connecting piece 53 is sleeved on the outer side of the outer wall of the two limiting columns 52, serving as a bridge connecting the lifting rod 51 and the buckling plate 54 to ensure their coordinated connection. The buckling plate 54 is buckled on the outer wall of the sampling tube 6, and ensures that the vibration can be effectively transmitted to the inside of the sampling tube 6 through the through hole. The vibration part 55 is installed on the buckling plate 54, and by providing impact force, it helps to loosen and push the core sample out of the inner wall of the sampling tube 6 smoothly, reducing the obstruction caused by friction or adhesion, thereby improving the efficiency and smoothness of the sample.

[0030] In some examples, further, a locking nut is provided on the lifting rod 51 , and the locking nut is used to lock the insertion position of the lifting rod 51 in the vertical pole 34 .

[0031] In this example, the locking nut on the lifting rod 51 is used to precisely control the height of the lifting rod 51 and ensure its fixed position. When the lifting rod 51 is inserted into the vertical rod 34, the operator can lock the position of the lifting rod 51 by rotating the locking nut, thereby preventing it from sliding up and down during operation.

[0032] In some examples, further, the limiting column 52 and the connecting member 53 are rotatable to buffer the impact force provided by the vibration part 55 to the sampling tube 6.

[0033] In this example, the rotational design between the stopper 52 and the connector 53 provides a shock-absorbing function to cushion the impact force exerted by the vibrating portion 55 on the sampling tube 6. By allowing the stopper 52 and the connector 53 to rotate freely during an impact, the device effectively disperses and absorbs the impact force generated by the vibrating portion 55, preventing direct transmission to the sampling tube 6 and causing damage or excessive stress concentration. This rotational buffering mechanism not only protects the sampling tube 6 and the core sample within it from excessive impact but also reduces wear and tear on the equipment, extending its service life.

[0034] In some examples, further, the vibration part 55 includes: a vibration motor 551, a protrusion 552, a connecting rod 553 and an impact block 554, the vibration motor 551 is fixed to the top of the buckling plate 54; the protrusion 552 is locked on the output end of the vibration motor 551 through a coupling; the impact block 554 passes through the through hole of the buckling plate 54, and is used to provide impact to the sampling tube 6; the two ends of the connecting rod 553 are respectively rotatably connected to the impact block 554 and the protrusion 552.

[0035] In this example, the vibration unit 55 provides effective impact force for the sampling tube 6, ensuring the smooth removal of the core sample. Specifically, the vibration motor 551 is fixed to the top of the buckling plate 54 as a power source. The rotational motion output by it is transmitted to the protrusion 552 locked at the output end through a coupling. The protrusion 552 rotates as the motor runs and transmits its motion to the impact block 554 through the connecting rod 553. The two ends of the connecting rod 553 are respectively connected to the impact block 554 and the protrusion 552 to ensure the smoothness and continuity of the motion transmission. The impact block 554 passes through the through hole on the buckling plate 54. When the vibration motor 551 is started, the impact block 554 is driven by the connecting rod 553 to periodically impact the sampling tube 6. Therefore, the vibration unit 55 effectively applies vibration force to the sampling tube 6 through the linkage of the motor drive and the mechanical structure, helping to loosen and remove the core sample, while avoiding damage to the tube body caused by directly applying excessive force, ensuring the efficiency of the discharge process.
