Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a geological environment monitoring device. Background Art

[0002] Through the geological environment monitoring device, we can grasp the dynamic change laws and characteristics of the geological environment, predict its occurrence and development trends, and put forward prevention, restoration and governance suggestions accordingly. Its ultimate goal is to protect the geological environment to the maximum extent, ensure the rational development and utilization of resources, and play a role in disaster prevention and mitigation.

[0003] The Chinese utility model with application number 202320104036.9 provides a geological environment monitoring device. This device uses a pushing mechanism and a drilling mechanism to make a drilling cone penetrate deep into the ground. During this process, the spiral blade will move down with the drilling cone and stir the mud and sand. After the drilling is completed, the drilling cone is recovered. At this time, the mud and sand at different depths will enter the collection box at the corresponding position of the spiral blade surface, thereby achieving the effect of sampling mud and sand at different depths.

[0004] Although this device can collect sediment at different depths into the corresponding collection box, in actual use, when the driving shaft drives the spiral blades and the collection box to recover upward, the spiral blades will scratch the surrounding sediment when rising, causing the sediment at different depths to fall into the collection box again during the rising process. This will change the depth distribution of the sample, resulting in the collected samples being unable to accurately reflect the differences in the original sedimentation environment.

[0005] Therefore, it is necessary to provide a geological environment monitoring device to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a geological environment monitoring device that can collect soil at various depths into a sampling plate, and during the rising process, can prevent soil at different depths from mixing into the sampling plate, thereby avoiding the influence of mixed soil on subsequent detection.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] The geological environment monitoring device comprises: a mobile vehicle, a lifting assembly is provided at the upper end of the mobile vehicle, the lifting assembly comprises: a hydraulic press, the output end of the hydraulic press is connected to a sampling assembly, the sampling assembly comprises: a driving shaft, an electric push rod is provided at the upper end of the driving shaft, and a plurality of concave holes are provided on the lower end surface of the driving shaft, a baffle is connected to the lower end of the electric push rod, the baffle is connected to a sampling plate through and through, the sampling plate is installed at the end of the concave hole, and a cone head is fixedly assembled at the bottom of the driving shaft.

[0009] Preferably, protrusions are provided on both sides of the sampling plate, the protrusions are matched with the concave holes provided on the driving shaft, and the protrusions and the concave holes are completely embedded and fixed.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-5As shown, the geological environment monitoring device provided by the utility model includes: a mobile vehicle 100, a lifting component 300 is provided at the upper end of the mobile vehicle 100, the lifting component 300 includes: a hydraulic press 310, the output end of the hydraulic press 310 is connected to the sampling component 400, the sampling component 400 includes: a driving shaft 440, an electric push rod 410 is provided at the upper end of the driving shaft 440, and a plurality of concave holes are provided on the lower end surface of the driving shaft 440, the lower end of the electric push rod 410 is connected to a baffle 420, the baffle 420 is connected to a sampling plate 430 through and through, the sampling plate 430 is installed at the end of the concave hole, and a cone head 441 is fixedly assembled at the bottom of the driving shaft 440. When in use, the tester first moves the mobile vehicle 100 to a suitable sampling area, and then connects the hydraulic press 310 to the driving shaft The cone head 441 installed at the bottom of 440 is used in conjunction with the driving shaft 440 to rotate underground until it reaches a suitable depth. At this time, it is driven by the electric push rod 410. The electric push rod 410 is the existing LA40 linear electric push rod 410. The electric motor in the electric push rod 410 converts the rotation operation into physical mechanical linear movement. By controlling the electric push rod 410, the baffle 420 is disengaged from the groove set in the sampling plate 430. Due to the disengagement of the baffle 420, the soil accumulated in the concave holes at both ends will flow into the sampling plate 430. When the device is retracted, the baffle 420 is moved downward by the electric push rod 410 until the baffle 420 is embedded in the sampling plate 430 and the baffle 420 blocks the concave hole set on the driving shaft 440.

[0027] By using the driving shaft 440, the concave hole and the sampling plate 430 in coordination, it is possible to collect soil at different depths. In actual use, after collecting the soil at different depths, the baffle 420 can be used to prevent the sampling plate 430 from being mixed with soil at different depths during its ascent. Compared with the existing method, this method can effectively prevent the mixing of soil at different depths when recovering the sampling plate 430, thereby preventing the collected samples from accurately reflecting the differences in the original sedimentary environment.

[0028] Second embodiment:

[0029] like Figure 3-4 As shown, protrusions 431 are provided on both sides of the sampling plate 430, and the protrusions 431 are adapted to the concave holes provided on the driving shaft 440, and the protrusions 431 are completely embedded and fixed in the concave holes. In actual use, when it is necessary to take out the sampling plate 430, the sampling plate 430 and the protrusions 431 are used in coordination. After the sampling is completed, since the sampling plate 430 is embedded in the inner wall of the concave hole provided on the driving shaft 440, it is relatively unchanged when actually taken out. Through the coordination of the protrusions 431, the sampling plate 430 can be easily taken out of the concave hole, which saves time for sampling and testing.

[0030] Third embodiment:

[0031] As shown in the figure, a falling blade 421 is provided at the lower end of the baffle 420, and the falling blade 421 is fixedly connected to the baffle 420. When the baffle 420 moves upward, some soil will penetrate into the mouth of the sampling plate 430. When the baffle 420 needs to be moved downward, some soil will be blocked in the recessed hole provided between the sampling plate 430 and the driving shaft 440, which will cause the baffle 420 to encounter resistance when moving downward. Due to the influence of the resistance, the load of the motor will increase. Secondly, since the resistance needs to be overcome, the motor needs to generate greater power, which may cause the current to increase, and the continuous resistance may cause the electric push rod 410 to wear faster, thereby affecting the service life of the equipment. In actual use, a fixed falling blade 421 is provided at the lower end of the baffle 420. The falling blade 421 can prevent the accumulation of soil, thereby making the baffle 420 move more smoothly when moving downward.

[0032] Fourth embodiment:

[0033] As shown in the figure, a movable plate 320 is provided at the lower end of the hydraulic press 310, and the movable plate 320 is fixedly connected to the electric push rod 410, and the movable plate 320 is slidably connected in the slide grooves provided in the limit plates 340 at both ends. Guide columns 330 are provided at both ends of the movable plate 320, and the guide columns 330 are slidably connected to the movable plate 320, and the guide columns 330 are fixed to the bottom of the mobile vehicle 100. In actual use, through the drive of the hydraulic press 310, the piston at the output end of the hydraulic press 310 will move downward, thereby driving the movable plate 320 and the guide columns 330 to move downward. The high-pressure capacity of the hydraulic press 310 can provide a more stable working platform, thereby ensuring the stability of the drive shaft 440 during the downward drilling process.

[0034] By using the guide column 330 in conjunction with the movable plate 320 and limiting the position of the guide column 330 , the movable plate 320 can be accurately aligned during the pressing process to avoid deviation, thereby ensuring the stability of the drive shaft 440 during operation.

[0035] Fifth embodiment:

[0036] As shown in the figure, a support assembly 200 is provided at the upper end of the mobile vehicle 100, and the support assembly 200 includes: a driving motor 210, and a support column 220 is provided at the output end of the driving motor 210, and the support column 220 is supported on the ground. In actual use, when the mobile vehicle 100 moves to a suitable sampling location, the driving motor 210 cooperates with the support column 220 to make the support column 220 move downward. The support columns 220 at the four corners of the mobile vehicle 100 push downward, which can effectively disperse the weight, reduce the center pressure, and make it more stable when the driving shaft 440 is working.

[0037] Working principle: The tester first moves the mobile vehicle 100 to a suitable sampling area, and then uses the hydraulic press 310 in conjunction with the cone head 441 assembled at the bottom of the drive shaft 440 to rotate the drive shaft 440 to a suitable depth. At this time, the electric push rod 410 is driven to control the electric push rod 410 so that the baffle 420 is disengaged from the groove provided in the sampling plate 430. Due to the disengagement of the baffle 420, the soil accumulated in the concave holes at both ends will flow into the sampling plate 430. When the device is retracted, the baffle 420 is moved downward by the electric push rod 410 until the baffle 420 is embedded in the sampling plate 430 and the baffle 420 blocks the concave hole provided on the drive shaft 440.

[0038] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
