Description

Technical Field

[0001] The invention relates to the technical field of hydrogeological engineering survey, and in particular to a hydrogeological engineering survey device. Background Art

[0002] Hydrogeology, a branch of geology, refers to the various changes and movement phenomena of groundwater in nature. Hydrogeology is the science of studying groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational utilization, the adverse effects of groundwater on engineering construction and mining and their prevention and control, etc. In hydrological engineering geological surveys, sampling is an important link in obtaining key data on the underground environment.

[0003] The existing announcement number is CN220304875U, and the name is a soil detection sampling device, which includes a bottom plate, a sampling port is opened in the middle of the bottom plate, a sampling tube is installed above the sampling port, and a fixing component is installed in the middle of the sampling tube. The fixing component includes a clamping plate, which is arc-shaped, and there are two of them, which are symmetrically distributed in the middle of the sampling tube. A frame pipe is arranged at the top of the clamping plate, and the top of the clamping plate is rotatably installed in the middle of the frame pipe. A compression spring is arranged in the middle of the frame pipe, and the two ends of the compression spring are respectively fixedly connected to the two clamping plates, and the two clamping plates are under the action of the compression spring. Keeping close to the sampling tube, a tightening bolt is installed on the side thread of the rack tube, and the end of the tightening bolt extends into the rack tube. The sampling tube is equipped with a first driving assembly, which drives the sampling tube to be inserted into the ground. The clamping plate is equipped with a second driving assembly, which drives the clamping plate to be inserted into the sampling tube. After the two clamping plates are brought close to each other to clamp the sample, the sampling tube is pulled out. In this operation mode, the sample will be clamped under the force of the clamping plate, thereby increasing the friction between the sample and the clamping plate, thereby reducing the risk of the sample falling, and effectively ensuring the success rate of sampling.

[0004] However, due to the lack of control over the sample core, the vibration force generated by the motor is directly transmitted to the sampling tube and the splint when the motor drives the sampling tube and the splint to rotate and move through the driving mechanism, and the sample core directly in contact with the sampling tube and the splint is also affected by the vibration force generated by the motor. During use, since the sampling head needs to drill into the soil to a certain depth, there is a problem of sample contamination during the downward movement of the sampling head. In addition, the structure of most sampling heads is generally simple, which has great limitations for the sampling of samples in different states, and further increases the risk of contaminating samples, thereby affecting the smooth progress of the sampling work and the accuracy of the sampling results.

[0038] Embodiment 1:

[0039] like Figures 1 to 5 As shown, a hydrogeological engineering survey device. The device includes a support member 1, a lifting member 2 and a material collection member. The support member 1 provides a stable structure to ensure that the device will not shift during the sampling process. The combination of the anchor frame 11 and the hole frame 18 enables the device to be stably fixed on the ground. The sliding cooperation between the slide frame 19 and the guide column 21 enables the lifting member 2 to move up and down smoothly, avoiding the shaking that may occur during the sampling process. The detachable assembly design of the drill bit 22 and the material collection member enables the sampling head to be replaced as needed to meet the sampling needs of samples in different states.

[0040] In a specific application, the support member 1 includes an anchor frame 11, a hole frame 18 and a slide frame 19. Two anchor frames 11 are symmetrically arranged, and a hole frame 18 is horizontally arranged on the upper part of the two anchor frames 11, and a slide frame 19 is vertically fixed on the top surface of the hole frame 18. The lifting member 2 includes a guide column 21 and a lower drill member 22. The guide column 21 vertically slides through and is assembled in the slide frame 19. The lower end of the guide column 21 is vertically arranged with a lower drill member 22, and the lower end of the lower drill member 22 is vertically assembled with a material collection member. Through this design, it is ensured that the sampling head can remain stable during the downward movement, thereby reducing the possibility of sample contamination.

[0041] In the implementation environment, the anchor frame 11 of the support member 1 is fixed to the sampling ground through the ground nail 12, which further enhances the stability of the device. The sliding hole in the slide frame 19 cooperates with the guide column 21, so that the guide column 21 can slide smoothly. The lower drill member 22 is connected to the guide column 21 through the slot 212 and the positioning rod 213, ensuring the stability and detachability of the lower drill member 22.

[0042] Specifically, a rack 211 is vertically embedded in one side of the guide column 21, and the rack 211 is meshed with the gear 191 at the top of the slide frame 19, and the guide column 21 is driven by the lifting motor 192 to move up and down. The lower drill 22 includes a socket seat 221, and a limit hole block is vertically fixed on the top surface of the socket seat 221. The limit hole block is inserted into the slot 212 of the guide column 21, and the lower drill 22 is stably connected by the sliding plug-in of the plug column 214 and the limit hole block. The design of the push screw 223 further ensures the smooth removal of the sample.

[0043] Compared with the prior art, the advantage of the present invention is that its structural design is more stable, which can effectively reduce the shaking of the sampling head during the downward movement, thereby reducing the risk of sample contamination. In addition, the detachable design of the lower drill piece 22 and the material collection piece enables the device to adapt to the sampling needs of samples in different states, further improving the accuracy and efficiency of the sampling work.

[0044] Through the cooperation of the support member 1, the lifting member 2 and the material taking member, the present invention successfully solves the problem of sample contamination during the downward movement of the sampling head. The support member 1 provides a stable foundation, the lifting member 2 ensures the smooth movement of the sampling head, and the detachable design of the material taking member enables the device to adapt to different sampling requirements. Therefore, the present invention not only improves the smooth implementation of the sampling work, but also ensures the accuracy of the sampling results.

[0045] In one embodiment, Figure 2 and 3 As shown, one side of the anchor frame 11 is fixed to the sampling ground by a ground nail 12, and two damping rods 13 are vertically symmetrically arranged on the top surface of the anchor frame 11, a pillar 14 is vertically fixed to the top of the damping rod 13, and a support spring 15 is vertically sleeved on the outside of the pillar 14, and the two ends of the support spring 15 are respectively fixed to the upper part of the pillar 14 and the top surface of the damping rod 13, a fixing frame 16 is vertically fixed to the pillar 14, and a screw hole seat 161 is horizontally fixed to the fixing frame 16, screw barrels 131 are horizontally fixed to the two damping rods 13, the top surface of the anchor frame 11 is fixed to the screw barrel 131 by assembling bolts 111, and the screw hole seat 161 is horizontally assembled with a bracket 17 by bolts.

[0046] The anchor frame 11 is fixed to the ground by the ground nail 12 to ensure the stability of the device during the sampling process. The setting of the damping rod 13 and the support 14 can provide buffering during the sampling process through the action of the support spring 15, reducing the impact of vibration on the sample. The combination of the fixing frame 16 and the screw hole seat 161 can ensure the stable installation of the bracket 17, so that the sampling head is more stable when drilling into the soil, reducing the possibility of sample contamination. Through the above-mentioned technical means, the technical solution of the present application solves the problem of sample contamination when the sampling head is drilling into the soil through the design of the fixing and buffering structure, and improves the accuracy and reliability of the sampling work.

[0047] One side of the anchor frame 11 is fixed to the sampling ground by a ground nail 12, which ensures that the anchor frame 11 will not move during the sampling process, thereby improving the stability of the device. The setting of the damping rod 13 can play a buffering role during the sampling process and reduce the impact of vibration on the sample. The combination of the pillar 14 and the support spring 15 can further enhance the buffering effect. The two ends of the support spring 15 are respectively fixed to the upper part of the pillar 14 and the top surface of the damping rod 13, which can provide sufficient support force when the sampling head drills down. The setting of the fixing frame 16 and the screw hole seat 161 can ensure the stable installation of the bracket 17 and prevent the sampling head from deviating when drilling into the soil.

[0048] The present application sets a ground nail 12 on the anchor frame 11 to make the entire device more stable during the sampling process, reducing sample contamination caused by the movement of the device. The combined design of the damping rod 13, the support 14 and the support spring 15 further reduces the impact of vibration on the sample and improves the accuracy of sampling by providing buffering and support. The setting of the fixing frame 16 and the screw hole seat 161 enables the bracket 17 to be firmly installed on the device, ensuring the stability of the sampling head when drilling into the soil, and further reducing the possibility of sample contamination. Therefore, the technical solution proposed in the present application has significant technical advantages in solving the problem of sample contamination during the sampling head drilling into the soil.

[0049] In one embodiment, Figure 4 As shown, a bracket 181 is vertically fixed on the top surface of the hole frame 18, and a slide frame 19 is vertically fixed on the top surface of the bracket 181, a through sliding hole is vertically penetrated on the top surface of the slide frame 19, and a guide column 21 is assembled in the sliding hole of the slide frame 19 for vertical sliding, a gear 191 is vertically rotatably connected to one side of the top slide of the slide frame 19, and a lifting motor 192 is horizontally fixed on the top of the slide frame 19, and the output end of the lifting motor 192 is fixed to the end of the gear 191.

[0050] The bracket 181 fixed vertically on the top surface of the hole frame 18 and the slide frame 19 fixed vertically on the top surface of the bracket 181 provide a support structure for the guide column 21, ensuring the stability of the guide column 21 in the vertical direction. The through-slide hole vertically penetrated on the top surface of the slide frame 19 and the guide column 21 assembled and vertically slid through the slide hole of the slide frame 19 ensure that the guide column 21 can slide smoothly in the slide frame 19. The gear 191 connected to the vertical rotation is penetrated on one side of the top slide of the slide frame 19, and the lifting motor 192 fixed horizontally on the top of the slide frame 19 is fixed to the end of the gear 191 by the output end of the lifting motor 192, so as to achieve precise control of the guide column 21. Through the cooperation of these technical features, the stability and precise control of the guide column 21 when vertically sliding in the slide frame 19 are achieved.

[0051] Furthermore, the fixing method of the bracket 181 and the slide frame 19 can be welding or bolting to ensure the stability of the structure. The sliding hole of the slide frame 19 can be precisely processed according to the size of the guide column 21 to ensure the smoothness of the guide column 21 during the sliding process. The connection between the gear 191 and the lifting motor 192 can be achieved by key connection or threaded connection to ensure the reliability of the transmission. The selection of the lifting motor 192 can be selected according to actual needs. Motors with different powers and speeds can be selected to adapt to different working environments.

[0052] Therefore, by vertically fixing the bracket 181 and the chute frame 19 on the top surface of the hole frame 18, and providing a through slide hole on the top surface of the chute frame 19, the guide column 21 can slide smoothly in the chute frame 19, thereby ensuring the stability of the guide column 21. The guide column 21 is precisely controlled by the gear 191 and the lifting motor 192 on the top of the chute frame 19. Compared with the prior art, the present application can effectively solve the stability and precise control problems of the guide column 21 when it slides vertically in the chute frame 19, thereby improving the working efficiency and sampling accuracy of the device.

[0053] In one embodiment, Figure 4 and 5 As shown, a rack 211 is vertically embedded in one side of the guide column 21, and the rack 211 is fixed on the outer end face of the guide column 21, and the rack 211 is meshed with the gear 191, a slot 212 is vertically opened at the bottom end of the guide column 21, and a positioning rod 213 is horizontally penetrated and slidably assembled on one side of the slot 212, a lifting spring 215 is horizontally sleeved on the outside of the positioning rod 213, and the two ends of the lifting spring 215 are respectively fixed on the end of the positioning rod 213 and the outer wall of the guide column 21, and a plug column 214 is horizontally fixed at one end of the positioning rod 213 located in the slot 212.

[0054] Through the meshing transmission of the rack 211 and the gear 191, the guide column 21 can be stably lifted and lowered, ensuring the stability of the guide column 21 during the lifting process. The slot 212 vertically opened at the bottom of the guide column 21 and the positioning rod 213 horizontally penetrated and slidably assembled can effectively realize the positioning of the guide column 21 and prevent the guide column 21 from being offset during operation. The lifting spring 215 horizontally sleeved on the outside of the positioning rod 213 allows the positioning rod 213 to return to its original position when not in use, ensuring the close fit between the positioning rod 213 and the slot 212, further improving the positioning accuracy of the guide column 21. The design of the plug 214 allows the positioning rod 213 to be stably fixed in the slot 212, ensuring the stability and positioning accuracy of the guide column 21 during operation.

[0055] The lifting spring 215 can be adjusted with different spring stiffness and length to adapt to different use environments and requirements. The materials of the positioning rod 213 and the plug post 214 can be selected from high-strength alloys or other wear-resistant materials to increase their service life and reliability. The meshing accuracy of the rack 211 and the gear 191 can be ensured by precision machining and assembly processes, thereby ensuring the smooth lifting and lowering of the guide post 21.

[0056] Through the comprehensive application of these technical features, the present application solves the stability and positioning accuracy problems of the guide column 21 during the lifting process, avoids the deviation of the guide column 21 during the working process, and thus improves the reliability and working efficiency of the overall device. Compared with the prior art, the present application provides a more stable and accurate positioning solution for the guide column 21, which significantly improves the performance and service life of the equipment.

[0057] In one embodiment, Figure 5 and Figure 6 As shown, the drill bit 22 includes a socket seat 221, a limiting hole block is vertically fixed on the top surface of the socket seat 221, the limiting hole block of the socket seat 221 is inserted into the slot 212 of the guide column 21, the plug column 214 is slidably plugged with the limiting hole block, and a drill motor 222 is vertically fixed on the bottom surface of the socket seat 221, and a pushing screw 223 is vertically fixed on the output end of the drill motor 222.

[0058] The drill bit 22 includes a socket seat 221, a limit hole block, a slot 212, a plug post 214, a drill motor 222 and a push screw 223. These technical features play a role in solving the problem of sample contamination by cooperating with each other.
