Description

Technical Field

[0001] This invention relates to the field of sampling equipment technology, specifically a hydrogeological distribution detection sampler. Background Technology

[0002] Hydrogeological investigation, also known as hydrogeological survey, refers to the hydrogeological investigation and research work conducted to ascertain the hydrogeological conditions of a region. Its aim is to understand the formation, distribution, and movement patterns of groundwater and surface water. This provides a basis for the rational exploitation and utilization of water resources and for the correct design and construction of foundation and piling projects. It includes both underground and above-ground hydrogeological investigation.

[0003] Traditional sampling devices can only perform simple sampling operations. When sampling at different depths, manual positioning and sampling are required repeatedly, which is cumbersome and inefficient. Furthermore, they cannot accurately quantify samples. In addition, traditional sampling devices may result in impure samples. All of these factors can lead to inaccurate analytical and testing values. Summary of the Invention

[0004] This invention provides a hydrogeological distribution detection sampler, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A hydrogeological distribution detection sampler includes a base frame and mounting columns on both sides of the base frame, with mounting rods fixedly connected to the top of the mounting columns. A sampling mechanism located below the mounting rods includes multiple sampling cylinders. Each sampling cylinder has a feed inlet on its side wall, and a material-collecting rod is mounted on the feed inlet. A pressure-accumulating cylinder is fixedly connected to the inner wall of the sampling cylinder on one side of the material-collecting rod. A valve rod is slidably inserted through the pressure-accumulating cylinder, and a vent is provided on the valve rod. A telescopic assembly is provided on one side of the pressure-accumulating cylinder, with a linkage rod at one end and a transmission rod hinged to the other end. The transmission rod is hinged to the material-collecting rod. A material-carrying assembly is located inside the sampling cylinder and connected to the valve rods. A gas transmission groove is provided on the side wall of the sampling cylinder. A valve cylinder is located at the top of the sampling cylinder, with a valve assembly mounted on it. A telescopic tube is located at the top of the valve cylinder, with one end of the telescopic tube communicating with the gas transmission groove of the upper sampling cylinder.

[0007] As a preferred embodiment of the present invention, the telescopic component includes a piston block slidably disposed inside the accumulator cylinder, a piston column fixedly connected to one side of the piston block, a telescopic member sleeved at one end of the piston column, the piston column extending to the outside of the accumulator cylinder, and the end of the piston column being hinged to a linkage rod.

[0008] As a preferred embodiment of the present invention, the material loading assembly includes a support plate slidably disposed inside the sampling cylinder, the support plate being slidably connected to the sampling cylinder, a positioning block being fixedly connected to the bottom wall of the sampling cylinder below the support plate, and an elastic element being fixedly connected between the positioning block and the support plate. The elastic element may be a spring or an elastic metal sheet with telescopic properties.

[0009] As a preferred embodiment of the present invention, the valve assembly includes a stop rod that is slidably disposed on the valve cylinder, a trapezoidal block that is fixedly connected to one end of the stop rod, a reset member that is fixedly connected between the trapezoidal block and the valve cylinder, the trapezoidal block that is correspondingly disposed to the valve rod, an opening that is opened at one end of the stop rod, a vent pipe that is fixedly connected to the top of the sampling cylinder, the vent pipe that is connected to the gas transmission groove, and one end of the vent pipe that is connected to the valve cylinder.

[0010] As a preferred embodiment of the present invention, the bottom of the mounting rod is fixedly connected to a hydraulic telescopic column, the bottom of the hydraulic telescopic column is fixedly connected to a drive motor, the bottom of the output shaft of the drive motor is fixedly connected to a rotating disk, the bottom of the rotating disk is fixedly connected to a fixing rod, and the bottom of the fixing rod is fixedly connected to a sampling cylinder.

[0011] As a preferred embodiment of the present invention, a buzzer is fixedly connected to the top of the sampling cylinder below the rotating disk, the buzzer is connected to the sampling cylinder, the bearing disk is fixedly connected to the valve stem, the valve stem has multiple vents, and the multiple vents are intermittently arranged, and an electric telescopic rod is fixedly arranged between the sampling cylinders.

[0012] This invention has the following advantages: Before using the device, a drilling device is needed to drill a hole of the corresponding depth in the corresponding area. Then, the sampling cylinder is lowered into the sampling hole using a hydraulic telescopic column. When the required sampling depth is reached, the air supply pump can be turned on to fill the accumulator cylinder with air through the air transmission groove. The piston column in the lowest sampling cylinder moves laterally. Under the action of the linkage rod and transmission rod, the sampling rod rotates and opens, contacting the inner wall of the sampling hole. Then, under the action of the drive motor, the sampling cylinder rotates, and sampling is achieved through the sampling rod. As sampling proceeds, the material on the support plate gradually increases. The support plate drives the valve rod to move down, and the number of air vents on the valve rod connected to the accumulator cylinder decreases. When the material on the support plate reaches the standard amount, the support plate drives the valve rod to move down to the maximum position. At this time, all the air vents on the valve rod are removed from the accumulator cylinder. When the accumulator cylinder loses its gas pressure support, the piston column resets under the action of the telescopic component, driving the sampling rod to close via the transmission rod and linkage rod, ceasing sampling. During this process, after the valve rod moves down, the trapezoidal block above the sampling cylinder resets under the action of the reset component, and the port on the stop rod moves into the valve cylinder. The air supply pump then fills the accumulator cylinder in the previous sampling cylinder with air, and the corresponding sampling rod opens to start sampling. When all sampling cylinders have finished sampling, the gas from the air supply pump is sent to the buzzer to sound an alarm. This sampling method ensures consistency in the amount of multiple samples, facilitating subsequent quantitative comparison and testing, making the test results more convincing. At the same time, closing the sampling cylinder after testing ensures the purity of the sample, resulting in more accurate test results. Furthermore, the device is easy to operate, has higher sampling efficiency, and is more practical. Attached Figure Description

[0027] The valve assembly 36 includes a stop rod 11 that is slidably disposed on the valve cylinder 10. One end of the stop rod 11 is fixedly connected to a trapezoidal block 9. A reset member 13 is fixedly connected between the trapezoidal block 9 and the valve cylinder 10.

[0030] In the implementation of this invention, before using the device, a drilling device is needed to drill a hole of the corresponding depth in the corresponding area. Then, the sampling cylinder 3 is lowered into the sampling hole through the hydraulic telescopic column 16. When the required sampling depth is reached, the air supply pump 30 can be turned on to fill the accumulator cylinder 32 with air through the air transmission groove 29.

Under the action of the telescopic component 26, the piston column 25 resets and drives the sampling rod 4 to close via the transmission rod 19 and the linkage rod 24, ceasing sampling. During this process, after the valve rod 8 moves down, the trapezoidal block 9 above the sampling cylinder 3 resets under the action of the reset component 13. The port 31 on the stop rod 11 moves into the valve cylinder 10, and the air supply pump 30 inflates the pressure cylinder 32 in the previous sampling cylinder 3. The corresponding sampling rod 4 opens and then samples are taken. When all samples in the sampling cylinder 3 are taken, the gas on the air supply pump 30 is sent to the buzzer 12 to sound an alarm. This sampling method of the device can ensure the consistency of the amount of multiple samples, which facilitates subsequent quantitative comparison and detection, making the detection results more convincing. At the same time, after the detection is completed, the sampling cylinder 3 is closed, which can ensure the purity of the sample and make the detection results more accurate. In addition, the device is easy to operate and use, has higher sampling efficiency, and is more practical.
