Description

Technical Field

[0001] The present invention relates to the technical field of sludge sampling, and particularly to a detection and sampling device for muddy sediment at the bottom of a tidal flat. Background Art

[0002] The tidal flat ecosystem is a complex whole, and the chemical properties of the sludge will affect the health of the ecosystem. For example, heavy metal pollution in the tidal flat sludge may be transmitted through the food chain, poisoning the tidal flat organisms and other organisms that feed on the tidal flat organisms. Detecting the chemical properties of the sludge can help us monitor whether the ecosystem is polluted and evaluate the degree of pollution.

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

[0019] A kind of detection and sampling device for silt at the bottom of tidal flats provided by the present invention has the following beneficial effects:

[0020] 1. By setting up a sampling mechanism, it is possible to dilute the silt with water when sucking and sampling the silt. Diluting the silt can better disperse various components in the silt. The components of tidal flat silt are complex and uneven.

[0021] 2. By setting up a sample processing mechanism, the obtained silt can be directly placed inside the sample cup. Direct placement can reduce unnecessary contact between the silt and the external environment, thereby maintaining the original state of its chemical composition. There may be complex chemical equilibria among many chemical substances in the silt, such as organic pollutants, heavy metals, and various minerals. Directly putting it into the sample cup can avoid chemical property changes caused by contact with air or other factors that may trigger chemical reactions.

[0022] 3. By setting up a material distribution mechanism, the obtained silt sample can be divided. The separated silt samples facilitate the conduct of comparative experiments. Different treatment methods can be applied to the separated samples to study the effects of these treatment methods on the physical, chemical, and mechanical properties of the silt.

Detailed implementation manners

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the scope of protection of the present invention.

[0037] Refer to Figures 1-11, this technical solution provides a device for detecting and sampling bottom silt in tidal flats, specifically including a chassis 1. Track wheels 2 are installed at the bottom of the chassis 1, and the track wheels 2 can ensure that the entire sampling device can move smoothly on the surface of the tidal flat. A sampling mechanism 3 is installed at the bottom of the chassis 1. The sampling mechanism 3 includes a silt pump 301, an electric telescopic rod 303, and a drill pipe 306. The silt pump 301 is fixedly installed on the top of the chassis 1. There are two silt pumps 301. Suction pipes 302 are fixedly installed at the bottoms of the two silt pumps 301. The electric telescopic rod 303 is fixedly installed at the bottom of the chassis 1. The output end of the electric telescopic rod 303 is fixedly installed with a mounting plate 304. A telescopic hose 305 is fixedly installed on the top of the mounting plate 304. There are two telescopic hoses 305, and both of the two telescopic hoses 305 are fixedly connected to the suction pipe 302. The drill pipe 306 is fixedly installed at the bottom of the mounting plate 304. There are two drill pipes 306, and the two drill pipes 306 are fixedly connected to the telescopic hose 305. Filter grilles are fixedly installed at the bottoms of the two drill pipes 306. When it is necessary to sample the silt, 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 at the same time insert the drill pipe 306 into the silt. The filter grille can filter the garbage in the silt. Under the action of the silt pump 301, the silt enters the inside of the telescopic hose 305 through the drill pipe 306, and then enters the inside of the suction pipe 302 from the telescopic hose 305. A first sliding rod 307 is installed at the bottom of the mounting plate 304. There are two first sliding rods 307, and both of the two first sliding rods 307 penetrate through 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 sliding rod 307. First springs 309 are sleeved on the surfaces of the two first sliding rods 307. 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 directly above the front first sliding rod 307. The pressure plate 308 can detect the viscosity of the silt. When the viscosity of the silt is relatively high, the silt pump 301 may not be able to suck the silt, resulting in sampling failure. When the viscosity of the silt is small, the pressure plate 308 can move downward together with the mounting plate 304. When the pressure plate 308 encounters silt with a relatively high viscosity, under the resistance of the silt, the pressure plate 308 will move upward relative to the mounting plate 304. The upward movement of the pressure plate 308 can drive the first sliding rod 307 to move upward, and then can compress the first spring 309. The upward movement of the first sliding rod 307 can squeeze the pressure button 310. The pressure button 310 can convert the pressure signal into an electrical signal according to the pressure change corresponding to the pressing depth, and the intensity of the electrical signal is related to the pressing depth. These electrical signals can be used by subsequent circuits or controllers to adjust the magnitude of the power output.A water tank 311 is fixedly installed at the bottom of the chassis 1. A water outlet pipe 312 is fixedly installed at the bottom of the water tank 311. An electromagnetic valve 313 is installed inside the water outlet pipe 312. The electromagnetic valve 313 is connected to the pressure button 310 through an electrical signal. When the force received by the pressure button 310 is greater, the opening and closing degree of the electromagnetic valve 313 is greater, and thus the water flow rate inside the water outlet pipe 312 is also more. A water delivery hose 314 is fixedly installed at the bottom of the water outlet pipe 312. A water spray pipe 315 is fixedly installed at the bottom of the pressure plate 308. The top of the water spray pipe 315 is fixedly connected to the water delivery hose 314. A first sliding cylinder 316 is rotatably installed at the bottom of the chassis 1. A toothed rod 317 is slidably installed inside the first sliding cylinder 316. The bottom of the toothed rod 317 is rotatably connected to the mounting plate 304. A first stirring rod 318 is rotatably installed at the bottom of the mounting plate 304. The first stirring rod 318 is fixedly connected to the toothed rod 317. Through the settings of the water spray pipe 315 and the first stirring rod 318, when the sludge viscosity encountered during the sampling process is relatively high and it is difficult for the sludge pump 301 to suck, the electromagnetic 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, and through the setting of the first stirring rod 318, the sludge is diluted, ensuring that the sampling device can sample sludge with different viscosities.,

[0038] Refer to Figures 1-11, this embodiment also proposes that a sample processing mechanism 4 is installed on the top of the chassis 1. The sample processing mechanism 4 includes a placement plate 401. The placement plate 401 is fixedly installed on the top of the chassis 1. A first motor 402 is fixedly installed on the top of the placement plate 401. The first motor 402 adopts the model of a reciprocating motor. A vertical plate 403 is fixedly installed on the top of the chassis 1. A first pulley 404 is rotatably installed on the side of the vertical plate 403. The first pulley 404 is fixedly connected to the output end of the first motor 402. The first motor 402 can drive the first pulley 404 to rotate reciprocally. A sliding track 405 is fixedly installed on the side of the vertical plate 403. A receiving bin 406 is fixedly installed on the top of the sliding track 405. The sludge pump 301 is connected to the receiving bin 406 through a pipeline. The sludge sucked through the suction pipe 302 enters the interior of the receiving bin 406 through the pipeline. The sludge can be discharged from the bottom of the receiving bin 406. A sliding plate 407 is slidably installed inside the sliding track 405. A transport pipe 408 is fixedly installed at the bottom of the sliding plate 407. The sliding plate 407 can block the bottom of the receiving bin 406 to prevent the sludge from falling. In the initial state, the transport pipe 408 is directly below the receiving bin 406, and the sludge can fall from the receiving bin 406 into the interior of the transport pipe 408. 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 it from falling from the interior of the receiving bin 406. A reinforcing plate 409 is fixedly installed on the side of the transport pipe 408. A first threaded rod 410 is fixedly installed on the side of the reinforcing plate 409. The first threaded rod 410 penetrates through the side of the vertical plate 403 and is slidably connected to the vertical plate 403. A first threaded cylinder 421 is rotatably installed on the side of the vertical plate 403. The first threaded cylinder 421 is threadedly connected to the first threaded rod 410. A second pulley 411 is fixedly installed on the side of the first threaded cylinder 421. A first rotating shaft 412 is rotatably installed on the side of the vertical plate 403. The first rotating shaft 412 penetrates through the side of the vertical plate 403 and is rotatably connected to the vertical plate 403. A third pulley 413 is fixedly installed at the end of the first rotating shaft 412. The third pulley 413 is connected to the second pulley 411 through a belt. A fourth pulley 414 is fixedly installed on the surface of the first rotating shaft 412. 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. A falling opening 416 is formed 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 thus can drive the first threaded cylinder 421 to rotate.The rotation of the first threaded barrel 421 can cause the first threaded rod 410 to move inside the first threaded barrel 421. The movement of the first threaded rod 410 can push the reinforcement plate 409 to move, and further push the transport pipe 408 to move inside the sliding track 405. Through this reciprocating motion, the transport pipe 408 can divide the sludge in the material receiving bin 406 into small portions, making each sludge sample more representative. A connecting column 417 is fixedly installed at the top of the sliding plate 407, and a first toothed plate 418 is fixedly installed at the top of the connecting column 417. A first gear 419 is rotatably installed at the top of the material receiving bin 406. The first toothed plate 418 meshes with the first gear 419. A second stirring rod 420 is rotatably installed inside the material receiving bin 406, and the second stirring rod 420 is fixedly connected to the first gear 419. When the sliding plate 407 slides inside the sliding track 405, it can drive the first toothed plate 418 to move back and forth, and further drive the first gear 419 to rotate. In this way, the second stirring rod 420 can be driven to rotate, and thus the sludge sample can be stirred.

[0039] Refer to Figures 1-11, this embodiment also proposes that a material distribution mechanism 5 is installed on the top of the placement plate 401. The material distribution mechanism 5 includes a second motor 501, which is fixedly installed on the top of the placement plate 401. The output end of the second motor 501 is fixedly installed with a second rotating shaft 502, and the end of the second rotating shaft 502 is fixedly installed with a first bevel gear 503. The second motor 501 can drive the second rotating shaft 502 to rotate, and the rotating second rotating shaft 502 can make the first bevel gear 503 rotate. A half gear 504 is rotatably installed on the top of the placement plate 401, and a second bevel gear 505 is fixedly installed on the top of the half gear 504. The second bevel gear 505 meshes with the first bevel gear 503. 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. A second gear 506 is rotatably installed on the top of the placement plate 401, and the second gear 506 meshes with the half gear 504. The first bevel gear 503 is fixedly connected to the first sliding cylinder 316, and the rotation of the first bevel gear 503 can drive the first stirring rod 318 to rotate. A placement disc 507 is fixedly installed on the top of the second gear 506. 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 disc 507 to rotate intermittently. The rotation interval of the placement disc 507 is the same as the movement interval of the transport pipe 408. A placement groove 508 is formed on the surface of the placement disc 507. There are multiple placement grooves 508, and sample cups 509 are slidably installed inside the multiple placement grooves 508. A sliding column 510 is slidably installed at the bottom of the placement disc 507. The bottom of the sliding column 510 is fixedly installed with a bottom plate 511. A pushing block 512 is fixedly installed on the top of the bottom plate 511. A second spring 513 is sleeved on the surface of the sliding column 510. The second spring 513 is arranged between the bottom plate 511 and the placement disc 507. A dust cover 514 is rotatably installed on the top of the placement disc 507. The dust cover 514 can prevent external pollutants from contaminating the sludge. When the pushing block 512 is pushed, the sliding column 510 can slide at the bottom of the placement disc 507, thereby compressing the second spring 513, and the pushing block 512 can enter the placement groove 508, ejecting the sample cup 509. When the sample cup 509 is ejected, the dust cover 514 can be lifted, and the final height of the sample cup 509 can be located inside the falling port 416, and the transport pipe 408 will also slide to the position of the falling port 416. The sludge inside the transport pipe 408 can fall into the sample cup 509. In this way, every time the placement disc 507 rotates a certain angle, each sample cup 509 can be directly below the falling port 416, enabling the sludge to smoothly enter the sample cup 509. A support plate 515 is fixedly installed at the bottom of the baffle 415. The first rotating shaft 412 penetrates to the side of the support plate 515 and is rotatably connected to the support plate 515.A rotating disk 516 is fixedly installed at the end of the first rotating shaft 412. An eccentric plate 517 is rotatably installed at the eccentric position of the rotating disk 516. A connecting rod 518 is slidably installed on the surface of the support plate 515. The top of the connecting rod 518 is rotatably connected to the eccentric plate 517. The bottom of the connecting rod 518 is fixedly installed with a connecting plate 519. The top of the connecting plate 519 is fixedly installed with a second sliding cylinder 520. The top of the second sliding cylinder 520 is fixedly installed with a fixing block 521. A sliding column 522 is fixedly installed on the top of the placing plate 401. The sliding column 522 is slidably connected to the second sliding cylinder 520. 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 can drive the second sliding cylinder 520 to slide up and down on the surface of the sliding column 522, so that the fixing block 521 can push the pushing block 512, and thus the sample cup 509 can be lifted.

[0040] Specifically, the working process or working principle of the beach bottom sludge detection and 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. 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 insert the drill pipe 306 into the sludge. The filter grille can filter the garbage in the sludge. Under the action of the sludge pump 301, the sludge enters the inside of the telescopic hose 305 through the drill pipe 306, and then enters the inside of the suction pipe 302 from the telescopic hose 305. When the viscosity of the sludge is small, the pressure plate 308 can move downward together with the mounting plate 304. When the pressure plate 308 encounters sludge with a higher viscosity, under the resistance of the sludge, the pressure plate 308 will move upward relative to the mounting plate 304. The upward movement of the pressure plate 308 can drive the first sliding rod 307 to move upward, and then can compress the first spring 309. The upward movement of the first sliding rod 307 can squeeze the pressure button 310. The solenoid valve 313 is connected to the pressure button 310 through an electric signal. When the force received by the pressure button 310 is greater, the opening and closing degree of the solenoid valve 313 is greater, and thus the water flow rate inside the water outlet pipe 312 is also more. And by combining with the first stirring rod 318, the sludge can be diluted to ensure the smooth progress of the sampling work.

[0041] Then start the first motor 402. The first motor 402 can drive the first pulley 404 to rotate reciprocally. The silt sucked through the suction pipe 302 enters the inside 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. 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 can 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. The movement of the first threaded rod 410 can push the reinforcing plate 409 to move, and then can push the conveying pipe 408 to move inside the sliding track 405. The silt that falls into the inside of the conveying pipe 408 can also move along with the conveying pipe 408. When the sliding plate 407 slides inside the sliding track 405, it can drive the first toothed plate 418 to move back and forth, and then can drive the first gear 419 to rotate, thereby driving the second stirring rod 420 to rotate, so as to stir the silt inside the receiving bin 406.

[0042] At the same time, start the second motor 501. The second motor 501 can drive the second rotating shaft 502 to rotate. The rotating second rotating shaft 502 can cause the first bevel gear 503 to 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 sliding 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 disk 507 to rotate intermittently. The rotation interval of the placement disk 507 is the same as the movement interval of the transport pipe 408. When the push block 512 is pushed, the sliding column 510 can slide at the bottom of the placement disk 507, thereby compressing the second spring 513. The push block 512 can enter the inside of the placement groove 508, pushing out the sample cup 509. When the sample cup 509 is pushed out, the dust cover 514 can be lifted. Moreover, the final height of the sample cup 509 can be located inside the falling port 416, and the transport pipe 408 will also slide to the position of the falling port 416. The silt inside the transport pipe 408 can fall into the sample cup 509. In this way, every time the placement disk 507 rotates a certain angle, each sample cup 509 can be directly below the falling port 416, enabling the silt to smoothly enter 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 sliding cylinder 520 to slide up and down on the surface of the sliding column 522. In this way, the fixed block 521 can push the push block 512, causing the sample cup 509 to rise and the silt to fall into the sample cup 509. After the staff finishes sampling, they can directly take out the sample cup 509 for inspection directly.
