Description

Technical Field

[0001] The present invention relates to the technical field of sludge sampling, and in particular to a device capable of accurately guiding columnar sampling of river and lake sediments and a method for using the device. Background Art

[0002] During the sampling process of river and lake bottom mud, traditional river and lake columnar mud sampling instruments cannot clearly detect the actual situation under the water area. Therefore, the instruments often cannot clearly know the water depth during sampling. After the columnar mud sampler completes sampling, there is no way to determine whether the sampling depth of the mud sampler has reached the mud sampling depth requirement. Therefore, we have designed a device that can accurately guide the sampler to take samples. This device intends to use a stress sheet sensing device to detect the sediment surface and the stress size when the columnar sampler stops excavation through stress sensing, and infer the sediment stratification. Therefore, how to design a device and method of use that has good stability, simple operation process, and accurate measurement results and can accurately guide the columnar sampling of river and lake sediments has become our current problem to be solved. Summary of the invention

[0003] The purpose of the present invention is to provide a device and a method for using the device that can accurately guide columnar sampling of river and lake sediments to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device capable of accurately guiding columnar sampling of river and lake sediments and a method of using the device, comprising a columnar sediment collector, a first guiding device and a second guiding device, the first guiding device and the second guiding device being symmetrically installed on both sides of the bottom of the columnar sediment collector, and a through hole being provided at the bottom of the columnar sediment collector, a fixing plate being fixedly installed at the top of the inner part of the second guiding device close to one side of the columnar sediment collector, three groups of first return springs being fixedly installed at the bottom of the fixing plate, a mounting plate being fixedly installed at the bottom of the first return spring, two groups of support rods being fixedly installed at the bottom of the mounting plate through guide rods, a mud guard being fixedly installed at the bottom of the support rods, a filter hole being provided at the bottom of the columnar sediment collector close to the second guiding device, and a filter hole being provided at the bottom of the second guide device. A hinged seat is fixedly installed on the top of the guiding device near the first return spring, and a closed door is rotatably installed inside the hinged seat; a second installation cavity is fixedly installed at the central position of the inner side of the second guiding device, an interrupter plate is fixedly installed at the central position inside the second installation cavity, a connecting cavity is fixedly installed on the side of the second installation cavity away from the second guiding device, a stress sheet is inlaid and installed on the side of the interrupter plate close to the connecting cavity, a third return spring is slidably installed inside the connecting cavity, one side of the third return spring is fixedly installed on the side of the closed door, and one end of the third return spring away from the closed door extends to the surface of the stress sheet, the first installation cavity is fixedly installed inside the first guiding device, and a battery and a data transmission port are fixedly installed inside the first installation cavity, respectively.

[0005] Preferably, scale marks are evenly distributed on the surface of the columnar sediment container.

[0006] Preferably, a filter cloth is fixedly mounted on the surface of the filter hole, and the mesh diameter of the filter cloth is less than 1 um.

[0007] Preferably, a protective frame plate is fixedly mounted on the bottom of the outer fixing plate of the first return spring.

[0008] Preferably, an elastic isolation frame is fixedly installed between the bottom of the closed door on the side away from the first return spring and the inner side of the second guiding device, and the second return spring is fixedly installed inside the elastic isolation frame.

[0009] The invention also provides a method for using a columnar sampling device that can accurately guide river and lake sediments:

[0010] When the first guide device, the second guide device and the columnar silt collector enter underwater, the fender will move upward under the action of water pressure, causing the first return spring to contract, and the water entering the columnar silt collector will be discharged through the filter hole. After the bottom silt enters the columnar silt collector, its pressure will continue to push the first return spring, thereby driving the closed door to make an offset movement around the hinge seat. At this time, the offset of the closed door will transmit the corresponding pressure to the stress sheet through the third return spring. The stress sheet then transmits the obtained data to the data transmission port through the signal line. Under the action of the battery, the data transmission port sends the signal data to an external computer for relevant data analysis.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the device and the method of use capable of accurately guiding columnar sampling of river and lake sediments make the overall stability of the device in underwater operation more excellent through the coordinated use of the three groups of first return springs and guide rods as well as support rods and protective frame plates, thereby avoiding the displacement of the mud guard due to different silt accumulation conditions, so that the mud guard as a whole can be kept on the same horizontal line for the lifting process, and at the same time, the protective frame plate protects the first return spring from tipping over. During the contraction of the first return spring, the first return spring will be tilted due to the action of the spring elastic force, and the protective frame plate avoids this situation from occurring, so that the first return spring always remains in a vertical state. At the same time, the coordinated use of the battery and the data transmission port enables the overall device to feed back the underwater measurement data to the ground computer database in real time, effectively avoiding the delay of the data. The coordinated use of the elastic isolation frame and the second return spring, on the one hand, ensures the dryness inside the second guide device, avoiding the risk of interference with the test results of the stress sheet, and on the other hand, realizes the opening and closing of the closed door, thereby achieving the purpose of overall measurement of the device.
