Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, and particularly relates to a sediment sampling device for water conservancy river regulation. Background Art

[0002] River regulation is one of the most important links in water conservancy projects. River regulation generally refers to the cleaning work of silt accumulation, floating objects, excessive plants or alien species inside the river. During the river regulation process, it is necessary to sample the sediment deposition in the river to understand the water quality situation in the river for investigation.

[0003] Patent No. CN21999660 discloses a sediment sampling device for water conservancy river regulation, which includes a sand pumping cylinder. The top of the sand pumping cylinder is fixedly installed with a sealing cylinder. The bottom end of the sand pumping cylinder is a conical opening structure. The top of the sealing cylinder is fixedly installed with a telescopic rod. The outer surface of the sand pumping cylinder near its top is fixedly installed with a connecting pipe communicating with its interior. The outer surface of the connecting pipe is threadedly connected with a sampling cylinder. Although the above-mentioned new type drives the auger shaft to rotate through a driving motor, so that the auger shaft rotates the sediment to the top of the sand pumping cylinder. While the auger shaft rotates, multiple sand throwing plates on the outer surface of the fixedly installed auger shaft will rotate accordingly, so that the sand throwing plates can throw the sediment into the sampling cylinder through the connecting pipe, facilitating the sampling operation of the sediment. And after the sampling is completed, the sampling cylinder can be directly unscrewed and a new sampling cylinder can be installed again, enabling continuous sampling multiple times and improving the sampling efficiency. However, during the use of the device, the bottom end of the sand pumping cylinder is in an open state. When it is necessary to extract sediment at a certain depth, the upper layer of sediment will be aspirated during the process of inserting into the sediment, thus affecting the test results. Content of the Utility Model

[0004] Aiming at the above problems, the purpose of the present utility model is to provide a sediment sampling device for water conservancy river regulation, which solves the problem that when the bottom end of the sand pumping cylinder is in an open state and it is necessary to extract sediment at a certain depth, the upper layer of sediment will be aspirated during the process of inserting into the sediment, thus affecting the test results.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows: A sediment sampling device for water conservancy river regulation includes a sampling pipe. A diversion cavity is provided inside the sampling pipe, and the top of the diversion cavity is connected to a chute in a through manner. A slide plate is slidably installed in the chute, and a screw conveyor shaft is installed at the center of the lower part of the slide plate. The screw conveyor shaft is installed inside the diversion cavity. A conical block is fixedly installed at the bottom end of the screw conveyor shaft, and the top end of the conical block is slidably connected to the bottom end of the diversion cavity. A placement cavity is provided inside the sampling pipe. One side of the placement cavity is hinged to one side of a first baffle, and a collection bottle is installed in the placement cavity. The top end of the collection bottle is threadedly connected to the bottom end of a quantitative cavity, and the quantitative cavity is provided inside the sampling pipe. An observation window is provided through the upper part of the sampling pipe for the quantitative cavity.

[0006] The beneficial effects of the utility model are as follows:

[0007] Before using this device, the electric telescopic rod is started through the control component, so that the limiting plate drives the sliding rod to slide upward, and the sliding rod sliding upward drives the slide plate to slide upward in the chute. The slide plate sliding upward drives the conical block connected to the screw conveyor shaft to block the bottom end of the diversion cavity upward. When the sampling pipe reaches the appropriate depth, the reverse operation is performed, so that the electric telescopic rod drives the limiting plate to slide downward, and the conical block slides downward to expose the bottom end of the diversion cavity, and then the sediment sampling can be started.

[0008] By rotating the screw rod, the second baffle can slide in the quantitative cavity, and by observing the observation window, the second baffle can be moved to the appropriate position to complete the adjustment of its internal capacity.

[0009] In order to limit the height of the extension rod after adjustment:

[0010] As a further improvement of the above technical solution: A support rod is fixedly installed at the top end of the sampling pipe, and an extension rod is slidably installed inside the support rod. The top end of the extension rod penetrates through the upper part of the support rod and is slidably connected thereto.

A bolt is threadedly installed through the rear side of the top end of the support rod, and one end of the bolt is threadedly connected to the rear side of the extension rod. A number of threaded holes are equidistantly provided on the rear side of the extension rod.

[0011] The beneficial effect of this improvement is that when using this device, the user can adjust the height of the extension rod according to the depth of the sampled sediment. First, rotate the bolt so that one end of it rotates out of the threaded hole. When the extension rod slides to the appropriate height, rotate the bolt so that one end of the bolt is threadedly connected to the threaded hole at the appropriate position, thereby limiting the height of the extension rod after adjustment.

[0012] In order to close the bottom end of the diversion cavity:

The sub-shaft of the motor is fixedly connected to one end of the auger shaft.

[0014] The beneficial effect of this improvement is: before using this device, the electric telescopic rod is started through the control component so that the limit plate drives the slide bar to slide upward, and the upward-sliding slide bar drives the sliding plate to slide upward in the chute. The upward-sliding sliding plate drives the conical block connected to the auger shaft to block the bottom end of the diversion cavity upward. When the sampling tube reaches the appropriate depth, operate in the reverse direction to make the electric telescopic rod drive the limit plate to slide downward, and the conical block slides downward to expose the bottom end of the diversion cavity, and then the sampling of sediment can be started.

[0015] In order to quantitatively sample sediment:

[0016] As a further improvement of the above technical solution: a number of sand throwing plates are fixedly installed on the outer side of the top end of the auger shaft. A connection through hole is opened through the inner wall of the quantitative cavity on one side of the inner wall of the top end of the diversion cavity. An electric telescopic plate is installed at the bottom end of the quantitative cavity, and the electric telescopic plate is installed inside the sampling tube.

[0017] The beneficial effect of this improvement is: the user threads the collection bottle at the bottom end of the quantitative cavity by opening the baffle one. At this time, the initial state of the electric telescopic plate closes the bottom end of the quantitative cavity. Then rotate the baffle one to close the placement cavity. By starting the motor, the auger shaft rotates to rotate and sample the sediment, and the rotating sand throwing plates throw the sediment into the quantitative cavity through the connection through hole, so as to store the sampled sediment. When the storage in the quantitative cavity is completed, the electric telescopic plate is started through the control component to expose the bottom end of the quantitative cavity, and the sediment in the quantitative cavity falls into the interior of the collection bottle, and the quantitative sampling of sediment can be completed.
