Description

Technical Field

[0001] The invention relates to the technical field of sludge sampling, in particular to a device for detecting and sampling sludge on a tidal flat bottom. Background Art

[0002] The tidal flat ecosystem is a complex entity, and the chemical properties of silt will affect the health of the ecosystem. For example, heavy metal pollution in tidal flat silt may be transmitted through the food chain, causing poisoning to tidal flat organisms and other organisms that feed on tidal flat organisms. Testing the chemical properties of silt can help us monitor whether the ecosystem is polluted and assess the extent of pollution.

[0003] Most existing sludge sampling devices directly insert the suction device into the sludge, which cannot dilute the sludge. Tidal flat sludge is usually a complex mixture composed of multiple particulate components, organic matter, water and various minerals. If the sludge is not diluted when it is sucked, due to the unevenness of the sludge itself, it is very likely that the sample components sucked will not represent the true situation of the entire sludge layer.

When it is necessary to sample the sludge, the staff extends the electric telescopic rod 303 to move the mounting plate 304 downward. The downward movement of the mounting plate 304 can drive the telescopic hose 305 to stretch and insert the drill pipe 306 into the sludge. The filter grid can filter the garbage in the sludge. Under the action of the sludge pump 301, the sludge enters the interior of the telescopic hose 305 through the drill pipe 306, and then flows out of the telescopic hose 305. The hose 305 enters the interior of the suction pipe 302, and a first slide bar 307 is installed at the bottom of the mounting plate 304. There are two first slide bars 307, and the two first slide bars 307 are both extended to the top of the mounting plate 304 and are slidably connected to the mounting plate 304. A pressure plate 308 is fixedly installed at the bottom of the first slide bar 307. The surfaces of the two first slide bars 307 are sleeved with first springs 309. The first springs 309 are arranged between the mounting plate 304 and the pressure plate 308. A pressure button 310 is fixedly installed at the bottom of the chassis 1. The pressure button 310 is arranged just above the front first slide bar 307. The pressure plate 308 can detect the viscosity of the sludge. When the viscosity of the sludge is relatively high, the sludge pump 301 may suck up the immovable sludge, leading to The first spring 309 is compressed by the pressure plate 308, and the first spring 309 is compressed by the pressure plate 308. The pressure plate 308 is pressed against the pressure plate 308, and the first spring 309 is compressed by the pressure plate 308.

A solenoid valve 313 is installed inside the water outlet pipe 312. The solenoid valve 313 is connected to the pressure button 310 through an electrical signal. When the pressure button 310 is subjected to a greater force, the solenoid valve 313 opens and closes more, and thus more water flows through the water outlet pipe 312. A water hose 314 is fixedly installed at the bottom of the water outlet pipe 312. The water hose 314 and the bottom of the pressure plate 308 are fixedly installed with a water spray pipe 315.

A first stirring rod 318 is rotatably mounted on the bottom of the mounting plate 304. The first stirring rod 318 is fixedly connected to the gear rod 317. Through the arrangement of the water spray pipe 315 and the first stirring rod 318, when the sludge viscosity encountered during the sampling process is high and makes it difficult for the sludge pump 301 to suck, the solenoid valve 313 can be opened and closed under the action of the pressure button 310, so that the water inside the water tank 311 is sprayed into the sludge through the water spray pipe 315. The sludge is diluted by the arrangement of the first stirring rod 318, ensuring that the sampling device can sample sludge of different viscosities.

A sliding rail 405 is fixedly installed on the side of the vertical plate 403, and a material receiving bin 406 is fixedly installed on the top of the sliding rail 405. The sludge pump 301 is connected to the sludge pump 301 through a pipeline. The receiving bin 406 is connected, and the sludge sucked by the suction pipe 302 enters the interior of the receiving bin 406 through the pipeline.

In the initial state, the transport pipe 408 is directly below the receiving bin 406, and the sludge can fall into the interior of the transport pipe 408 through the receiving bin 406. When the sliding plate 407 drives the transport pipe 408 to slide inside the sliding track 405, the sliding plate 407 can continue to block the sludge to prevent the sludge from falling out of the receiving bin. The interior of 406 falls down, and a reinforcing plate 409 is fixedly installed on the side of the transport tube 408. A first threaded rod 410 is fixedly installed on the side of the reinforcing plate 409.

The fourth pulley 414 is connected to the first pulley 404 through a belt. A baffle 415 is fixedly installed on the side of the vertical plate 403, and a drop opening 416 is opened on the surface of the baffle 415. When the first pulley 404 rotates, the first pulley 404 can drive the fourth pulley 414 to rotate. The rotating fourth pulley 414 can drive the first rotating shaft 412 to rotate. The rotation of the first rotating shaft 412 can drive the third pulley 413 to rotate. The rotation of the third pulley 413 can drive the second pulley 411 to rotate, and then drive the first threaded cylinder 421 to rotate.The rotation of the first threaded cylinder 421 can make the first threaded rod 410 move inside the first threaded cylinder 421, and the movement of the first threaded rod 410 can push the reinforcing plate 409 to move, and then push the transport pipe 408 to move inside the sliding track 405. With this reciprocating motion, the transport pipe 408 can divide the sludge inside the receiving bin 406 into small portions, so that each sludge sample is more representative. The top of the sliding plate 407 is fixedly installed with a connecting column 417, and the top of the connecting column 417 is fixedly installed with a first tooth plate 4 18.

The rotation of the rotating disk 516 can drive the connecting rod 518 to move up and down, and then drive the second slide 520 to slide up and down on the surface of the sliding post 522. In this way, the fixed block 521 can push the pushing block 512, thereby causing the sample cup 509 to rise.

[0040] Specifically, the working process or working principle of the mudflat bottom silt detection sampling device is as follows: the staff moves the entire device to the place where sampling is required, and then starts the electric telescopic rod 303, and the electric telescopic rod 303 drives the mounting plate 304 to move downward. The downward movement of the mounting plate 304 can drive the telescopic hose 305 to stretch, and at the same time, the drill pipe 306 is inserted into the silt. The filter grid can filter the garbage in the silt. Under the action of the silt pump 301, the silt enters the interior of the telescopic hose 305 through the drill pipe 306, and then enters the interior of the suction pipe 302 from the telescopic hose 305. When the viscosity of the silt is small, the pressure plate 308 can follow the mounting plate 304 to move upward. The first spring 309 is compressed and the pressure plate 308 is opened and closed, and the solenoid valve 313 is opened and closed, and the solenoid valve 313 is opened and closed, and the solenoid valve 313 is opened and closed, and the water flow through the water outlet pipe 312 is greater. In combination with the first stirring rod 318, the sludge can be diluted to ensure smooth sampling.

[0041] Then start the first motor 402, the first motor 402 can drive the first pulley 404 to rotate back and forth, and the sludge sucked by the suction pipe 302 enters the interior of the receiving bin 406 through the pipeline. When the first pulley 404 rotates, the first pulley 404 can drive the fourth pulley 414 to rotate, and the rotating fourth pulley 414 can drive the first rotating shaft 412 to rotate. The rotation of the first rotating shaft 412 can drive the third pulley 413 to rotate, and the rotation of the third pulley 413 can drive the second pulley 411 to rotate, and then drive the first threaded cylinder 421 to rotate, and the first threaded cylinder 42 1 can make the first threaded rod 410 move inside the first threaded cylinder 421, and the movement of the first threaded rod 410 can push the reinforcing plate 409 to move, and then push the transport pipe 408 to move inside the sliding track 405, and the sludge that falls into the transport pipe 408 can also move with the transport pipe 408. When the sliding plate 407 slides inside the sliding track 405, it can drive the first tooth plate 418 to move back and forth, and then drive the first gear 419 to rotate, thereby driving the second stirring rod 420 to rotate, so as to stir the sludge inside the docking silo 406.

[0042] At the same time, the second motor 501 is started, and the second motor 501 can drive the second rotating shaft 502 to rotate. The rotating second rotating shaft 502 can make the first bevel gear 503 rotate. When the first bevel gear 503 rotates, it can drive the second bevel gear 505 to rotate, and then drive the half gear 504 to rotate. The first bevel gear 503 is fixedly connected to the first slide cylinder 316. The rotation of the first bevel gear 503 can drive the first stirring rod 318 to rotate. The rotation of the half gear 504 can drive the second gear 506 to rotate intermittently, and the rotation of the second gear 506 can drive the placement plate 507 to rotate intermittently. The rotation interval of the placement plate 507 is the same as the movement interval of the transport tube 408. When the pushing block 512 is pushed, the sliding column 510 can slide on the bottom of the placement plate 507, thereby compressing the second spring 513, and the pushing block 512 can enter the interior of the placement groove 508, so that the sample cup 509 is pushed out. 9 is pushed out, the dust cover 514 can be opened at the same time, and the final height of the sample cup 509 can be located inside the drop port 416, and the transport tube 408 can also slide to the position of the drop port 416, and the sludge inside the transport tube 408 can fall into the interior of the sample cup 509. In this way, whenever the placement plate 507 rotates a certain angle, each sample cup 509 can be located directly under the drop port 416, so that the sludge can smoothly enter the interior of the sample cup 509. When the first rotating shaft 412 rotates, it can drive the rotating disk 516 to rotate. The rotation of the rotating disk 516 can drive the connecting rod 518 to move up and down, and then drive the second slide cylinder 520 to slide up and down on the surface of the slide column 522, so that the fixed block 521 pushes the pushing block 512, so that the sample cup 509 is raised, and the sludge falls into the interior of the sample cup 509. After the sampling is completed, the staff can directly take out the sample cup 509 for direct inspection.
