Description

Technical Field

[0001] The utility model belongs to the technical field of floating mud samplers, and relates to an underwater floating mud measuring sampler. Background Technique

[0002] After the sediment carried by the river is deposited in the estuary and coastal areas, it is often necessary to regularly sample and measure the underwater floating mud. Therefore, a sampler is needed to sample and measure the underwater floating mud. When the existing floating mud sampler samples the underwater floating mud, the floating board will float on the water surface, and the floating board will float with the water flow, resulting in the synchronous movement of the sampling block, which is not convenient for the sampling block to sample the underwater floating mud. For example, as shown in an underwater floating mud measuring sampler with the publication number CN202223408976.1, when the motor is started, the threaded rod rotates to drive the baffle to slide upward. When the through hole coincides with the floating mud inlet, the water containing floating mud flows into the sampling block, and the sampling of the underwater floating mud can be completed.

[0003] However, due to the lack of a fixing device for the floating board, the floating board will move with the water flow, which will cause the synchronous movement of the sampling block, and it is not convenient to sample the underwater floating mud through the sampling block. In addition, it is necessary to lift out the fixing frame in the sampling block by binding the lifting rope to the lifting ring, which is time-consuming and laborious and not convenient to take out the sampling block. Summary of the Invention

[0004] In order to achieve the above object, the utility model provides an underwater floating mud measuring sampler, which solves the problems that the floating board in the existing device is easy to move with water and the sampling block is not convenient to take out.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is an underwater floating mud measuring sampler, which includes a floating board floating on the water surface. A sampling cylinder for being placed in deep water is fixedly installed at the top end of the floating board. A sampling device for sampling underwater floating mud is arranged at the top end of the floating board. A fixing device for fixing the floating board is arranged at the top end of the floating board. An opening and closing device for opening the sampling cylinder is arranged in the cylinder body of the sampling cylinder. The sampling device includes a fixing column fixedly installed at the top end of the floating board. A sampling assembly for sampling floating mud in deep water is arranged in the cylinder cavity of the sampling cylinder. A lifting assembly for moving the sampling assembly up and down is arranged in the column cavity of the fixing column. The fixing device includes a first fixing assembly and a second fixing assembly fixedly installed at the top end of the floating board for fixing the floating board.

[0006] Further, the left end of the sampling cylinder is provided with a first water inlet for the floating sludge in deep water to enter the sampling assembly. There are two first water inlets. A storage groove for the lifting device to move up and down is provided on the cylinder body of the sampling cylinder. The right end of the sampling cylinder is provided with a filtering groove for discharging the water in the sampling cylinder.

[0007] Further, the lifting assembly includes a threaded rod rotatably arranged in the column body of the fixed column. The top end of the threaded rod is fixedly installed with a motor for driving the threaded rod to rotate.

[0008] Further, the sampling assembly includes a sampler for sampling the floating sludge in deep water. A support column is fixedly installed at the top end of the sampler. There are four support columns. A top plate is fixedly installed at the top ends of the four support columns. A moving block for threadedly connecting with the threaded rod is fixedly installed at the rear end of the top plate. One end of the moving block is located in the groove provided on the fixed column and is slidably connected to the fixed column.

[0009] Further, the right end of the sampler is provided with two drain grooves for discharging the water in the sampler. The left side of the sampler is provided with two second water inlets for the floating sludge in deep water to flow into the sampler.

[0010] Further, the first fixing assembly includes fixing plates fixedly installed on the top end of the floating plate. There are two fixing plates. A rotating shaft for rotation is arranged between the two fixing plates. A handwheel for driving the rotating shaft to rotate is fixedly installed at the front end of the rotating shaft. A lifting rope is wound around the shaft body of the rotating shaft. A fixing block for fixing the floating plate is fixedly installed at the bottom end of the lifting rope.

[0011] Further, the opening and closing device includes a sliding plate that moves up and down in the storage groove. A handle for driving the sliding plate to move up and down is fixedly installed at the top end of the sliding plate. A through groove is provided on the plate body of the sliding plate, and the groove width of the through groove is the same as the groove width of the first water inlet.

[0012] The beneficial effects of the present utility model are:

[0013] The utility model realizes sampling of underwater floating sludge by setting a sampling device, a fixing device and an opening and closing device. When sampling underwater floating sludge is required, first, the handwheel drives the rotating shaft to rotate, so that the fixing block at the bottom end of the suspension rope can be moved downward and sink to the bottom of the water, and then the floating plate can be fixed to prevent the floating plate from floating with the water flow. Then, the sliding plate is moved upward along the receiving groove by the handle, so that the through groove, the first water inlet and the second water inlet are communicated. At this time, the underwater floating sludge can enter the sampler along the first water inlet, the second water inlet and the through groove, and sampling of the underwater floating sludge can be realized. Finally, the motor drives the threaded rod to rotate, so that the moving block can move upward along the threaded rod to quickly lift the sampler in the sampling cylinder above the floating plate.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 8 shown, the present invention provides an underwater floating mud measurement sampler, including a floating board 100 floating on the water surface. A sampling cylinder 200 for being placed in deep water is fixedly installed at the top end of the floating board 100. A sampling device 300 for sampling underwater floating mud is arranged at the top end of the floating board 100. A fixing device 400 for fixing the floating board 100 is arranged at the top end of the floating board 100. An opening and closing device 500 for opening the sampling cylinder 200 is arranged inside the cylinder body of the sampling cylinder 200.

[0026] In some implementation modes, a first water inlet 203 for floating mud in deep water to enter the sampling assembly 330 is opened at the left end of the sampling cylinder 200, and there are two first water inlets 203. A storage tank 202 for the opening and closing device 500 to move up and down is opened on the cylinder body of the sampling cylinder 200, and the storage tank 202 penetrates through the first water inlet 203; A filtering tank 201 for discharging the water in the sampling cylinder 200 is opened at the right end of the sampling cylinder 200, so that when the floating board 100 needs to be taken out of the water, the water in the sampling cylinder 200 can be discharged along the filtering tank 201.

[0027] In some implementation modes, the sampling device 300 includes a fixed column 320 fixedly installed at the top end of the floating board 100. A sampling assembly 330 for sampling floating mud in deep water is arranged inside the cylinder cavity of the sampling cylinder 200. A lifting assembly 310 for moving the sampling assembly 330 up and down is arranged inside the column cavity of the fixed column 320.

[0028] Among them, the lifting assembly 310 includes a threaded rod 312 disposed inside the column body of the fixed column 320 for rotation, and the upper and lower ends of the threaded rod 312 are connected to the column body of the fixed column 320 through bearings to facilitate the rotation of the threaded rod 312; a motor 311 for driving the rotation of the threaded rod 312 is fixedly installed at the top end of the threaded rod 312, and the shaft end of the output shaft of the motor 311 is connected to the top end of the threaded rod 312 through a coupling. Thus, when the motor 311 operates, the threaded rod 312 rotates, and the sampling assembly 330 can be taken out from the floating mud in deep water.

[0029] In some embodiments, the sampling assembly 330 includes a sampler 334 for sampling the floating mud in deep water. A support column 333 is fixedly installed at the top end of the sampler 334, and there are four support columns 333, which are distributed in a rectangular array at the four corners of the top end of the sampler 334; a top plate 332 is fixedly installed at the top ends of the four support columns 333, and a moving block 331 for threadedly connecting with the threaded rod 312 is fixedly installed at the rear end of the top plate 332. One end of the moving block 331 is located in the groove opened on the fixed column 320 and is slidably connected to the fixed column 320. Thus, when it is necessary to take out the floating mud stored in the sampler 334, the motor 311 can be driven to drive the threaded rod 312 to rotate, so that the moving block 331 can move upward along the threaded rod 312, and the sampler 334 in the sampling cylinder 200 can be quickly lifted above the floating plate 100.

[0030] In some embodiments, drain grooves 335 for draining the water in the sampler 334 are opened at the right end of the sampler 334, and there are two drain grooves 335. Thus, when the sampler 334 moves upward, the excess water can be drained through the drain grooves 335 to facilitate sampling of the underwater floating mud by the sampler 334; second water inlets 336 for allowing the floating mud in deep water to flow into the sampler 334 are opened on the left side of the sampler 334, and there are two second water inlets 336. Thus, when it is necessary to sample the underwater floating mud through the sampler 334, the two first water inlets 203 can be made to communicate with the second water inlets 336 through the opening and closing device 500. At this time, the underwater floating mud can enter the sampler 334 along the first water inlets 203 and the second water inlets 336, and sampling of the underwater floating mud can be achieved.

[0031] In some embodiments, the fixing device 400 includes a first fixing assembly 410 and a second fixing assembly 420 fixedly installed at the top end of the floating plate 100 for fixing the floating plate 100.

[0032] Among them, the first fixing component 410 includes a fixing plate 411 fixedly installed on the top end of the floating plate 100. There are two fixing plates 411. A rotating shaft 413 for rotation is arranged between the two fixing plates 411. The front and rear ends of the rotating shaft 413 are connected to the two fixing plates 411 through bearings to facilitate the rotation of the rotating shaft 413. A handwheel 412 for driving the rotation of the rotating shaft 413 is fixedly installed at the front end of the rotating shaft 413. A lifting rope 414 is wound around the shaft body of the rotating shaft 413. A fixing block 415 for fixing the floating plate 100 is fixedly installed at the bottom end of the lifting rope 414 (shown as a schematic diagram in the figure, and the working principle is similar to that of an anchor). Thus, when it is necessary to fix the floating plate 100, the rotating shaft 413 can be driven to rotate by the handwheel 412, the fixing block 415 at the bottom end of the lifting rope 414 can be moved downward and sink to the bottom of the water, and then the floating plate 100 can be fixed to prevent the floating plate 100 from floating with the water flow, which is not convenient for the sampling device 300 to sample the floating mud underwater.

[0033] In some embodiments, the opening and closing device 500 includes a sliding plate 510 that moves up and down in the storage groove 202. A handle 530 for driving the up and down movement of the sliding plate 510 is fixedly installed at the top end of the sliding plate 510. A through groove 520 is formed on the plate body of the sliding plate 510, and the groove width of the through groove 520 is the same as the groove width of the first water inlet 203. Thus, when it is necessary to sample the floating mud underwater through the sampler 334, the sliding plate 510 can be moved upward along the storage groove 202 by the handle 530 to make the through groove 520, the first water inlet 203, and the second water inlet 336 communicate. At this time, the floating mud underwater can enter the sampler 334 along the first water inlet 203, the second water inlet 336, and the through groove 520, and the sampling of the floating mud underwater can be realized.

[0034] Each embodiment in this specification is described in a related manner. For the same and similar parts among the embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
