Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of marine sampling equipment, and particularly relates to a sampling and cleaning integrated equipment for marine shellfish sampling. BACKGROUND

[0002] Marine shellfish sampling refers to a process of sampling shellfish in the offshore sea, and a sample of the offshore shellfish is obtained through the sampling activity. Information such as the distribution of shellfish species, the growth condition, the enrichment of pollutants such as heavy metal ions in the shellfish, and the like is obtained through analysis and experimental detection of the shellfish sample, thereby providing important reference information for marine investigation activities, marine aquaculture activities, and the like. Marine shellfish sampling needs to be performed in a selected sea area. Compared with the sampling process on land, marine sampling usually has the characteristics that the situation of the seabed cannot be grasped and it is inconvenient to perform the sampling operation due to the obstruction of seawater. Therefore, there is currently no marine shellfish sampling equipment with a reasonable structure design and perfect functions, which leads to the fact that the sampling work of the offshore shellfish cannot be effectively carried out, and the effective acquisition of information such as the distribution of shellfish is limited.

[0003] The existing sampling tools are usually trawl nets or grab buckets, and the shellfish samples are obtained by lowering the trawl net to the seabed mud surface and dragging it or lowering the grab bucket to the seabed to grab the bottom mud. The foregoing sampling tools and sampling methods have the following defects: first, the operation mode of the trawl net and the grab bucket is difficult, the trawl net is not easy to control in the posture of the seabed due to light weight, and the problem of sampling failure often occurs, and the grab bucket can only grab the bottom mud at a single point at a time, and the sampling efficiency is very low; second, whether the trawl net or the grab bucket is used for sampling, the sampling object lifted to the sea surface includes a large amount of bottom mud, and the shellfish sample is wrapped in the bottom mud. In order to obtain the shellfish sample, it is necessary to clean on the sampling ship or after landing, and the bottom mud and the shellfish are separated through the cleaning operation, and the shellfish shell surface is brushed and cleaned. This cleaning operation is time-consuming and laborious, and increases the work burden of the sampling personnel.

[0004] In summary, it is necessary to develop and design a device specially used for sampling shellfish in marine bottom mud. The device should have a sampling capacity, and should also have a cleaning capacity for the bottom mud and the shellfish, so as to improve the sampling efficiency and the sampling effectiveness and reduce the work burden of the sampling personnel.

DETAILED DESCRIPTION

[0025] In order to further understand the application content, characteristics and effects of the application, the following examples are used for detailed description.

[0026] Please refer to Figure 1The sampling and cleaning integrated device for marine shellfish sampling of the present application comprises a towing platform which is settled on the sea bottom mud surface and is moved by a ship, a toothed component which is installed on the front of the towing platform and shovels the bottom mud on the moving path, a chain and rod type conveying belt 6 which is installed behind the toothed component and conveys the bottom mud, a floating water tank 5 which is installed inside the chain and rod type conveying belt 6 and has water holes on the top wall, and a floating submersible pump 4 which is installed on the towing platform and supplies water to the inside of the floating water tank 5.

[0027] The integrated device of the present application is lifted and controlled by a crane on the ship equipment and is moved on the sea bottom when the ship is running, and the state of the device when it is settled on the sea bottom mud surface is shown in Figure 1 When the device is moved forwardly, the toothed component on the front shovels the surface layer of the bottom mud (marine shellfish usually locates in the surface layer), and the mixture of the shovelled bottom mud, shellfish and stone blocks and the like is spread on the chain and rod type conveying belt 6 and is moved to the rear. The floating submersible pump 4 injects water into the floating water tank 5, and the water flow is sprayed upwardly from the water holes on the top wall of the floating water tank 5, so that the floating effect is generated on the mixture which passes above, the relatively light bottom mud and shellfish float upwardly, and the relatively heavy stone blocks and the like remain on the chain and rod type conveying belt 6, and finally the stone blocks and the like are separated from the rear end of the chain and rod type conveying belt 6 and fall on the sea bottom mud surface behind the device.

[0028] Please see Figure 2 It can be seen that the towing platform is composed of

[0029] The towing platform comprises oppositely arranged left side plate 27 and right side plate 1, front support 25 which is installed between the front parts of the left side plate 27 and the right side plate 1, and rear wheel assemblies which are installed on the outer sides of the rear parts of the left side plate 27 and the right side plate 1. As shown in the figure, the two ends of the front support 25 are respectively welded and fixed on the top of the front parts of the left side plate 27 and the right side plate 1, and when the integrated device is settled on the sea bottom mud surface, the two rear wheel assemblies fall on the sea bottom mud surface and roll and move along the sea bottom mud surface, so that the rear part of the device is lifted to a certain height, which is beneficial to the toothed component on the front to shovel the surface layer of the sea bottom mud surface.

[0030] In order to facilitate the towing movement of the integrated device, as shown in Figure 2 two forwardly extending support rods are welded and installed on the front of the front support 25, a towing connecting frame 26 is installed between the two support rods, and the hoisting cable which is retracted and extended by the ship crane is connected to the towing connecting frame 26.

[0031] In this embodiment, the rear wheel assembly comprises a wheel support 7 hingedly mounted on the bottom of the rear part of the side plate, and a rear wheel 8 is mounted on the wheel support 7. A wheel height adjuster 9 is further mounted between the rear wheel 8 and the side plate. The wheel height adjuster 9 is a basket bolt. Since the wheel support 7 is hingedly connected to the side plate, the wheel support 7 and the rear wheel 8 can swing up and down to adjust the height of the rear wheel 8. The height of the rear wheel 8 is adjusted by the wheel height adjuster 9. The basket bolt comprises an adjusting frame in the middle and two screw rods at the two ends. The upper end of one screw rod is hingedly connected to the side plate, and the other end of the other screw rod is hingedly connected to the rear end of the wheel support 7. When the height of the rear wheel 8 needs to be adjusted, the adjusting frame of the basket bolt is rotated to move the two screw rods closer or farther apart.

[0032] A drive wheel 29 is mounted between the front part and the rear part of the left side plate 27 and the right side plate 1. A chain-link conveyor belt 6 is mounted between the two groups of drive wheels 29. A conveyor belt drive machine 11 is fixedly mounted on the outside of the left side plate 27 or the right side plate 1. As shown in the figure, the conveyor belt drive machine 11 is fixedly mounted on the outside of the right side plate 1 to drive the rear drive wheels 29. Specifically, the chain-link conveyor belt 6 comprises a left chain and a right chain. A plurality of metal crossbars are mounted between the left chain and the right chain, and gaps are formed between adjacent metal crossbars. The shaft of the drive wheel 29 is mounted on the shaft seat on the left side plate 27 and the right side plate 1. A plurality of equiangularly spaced grooves are formed on the side wall of the drive wheel 29. The ends of the metal crossbars of the chain-link conveyor belt 6 are located in the grooves of the drive wheel 29. Therefore, the power output by the conveyor belt drive machine 11 can be stably transmitted to the chain-link conveyor belt 6 to make the chain-link conveyor belt 6 move stably.

[0033] The flotation water tank 5 is a flat tank. The two side edges of the flotation water tank 5 are fixedly connected to the left side plate 27 and the right side plate 1, respectively. The flotation submersible pump 4 is fixedly mounted on the outside of the left side plate 27 or the right side plate 1. As shown in the figure, the flotation submersible pump 4 is fixedly mounted on the outside of the right side plate 1. The outlet of the flotation submersible pump 4 is connected to the flotation water tank 5 through a pipeline. The flotation submersible pump 4 pumps the seawater around the device into the flotation water tank 5 in a pressurized manner. The water source in the flotation water tank 5 is jetted upward through the water holes in the top wall. The jetted water flows upward through the gaps between the metal crossbars of the chain-link conveyor belt 6 and acts on the mixture spread on the chain-link conveyor belt 6.

[0034] Considering that the debris on the seabed may be sucked into the flotation submersible pump 4 to cause a blockage problem, in this embodiment, a flotation water pump filter screen 24 is mounted on the inlet of the flotation submersible pump 4.

[0035] The tooth assembly comprises a tooth mounting frame 28 fixed between the front portions of the left side plate 27 and the right side plate 1, and a plurality of teeth 2 are mounted on the tooth mounting frame 28 in parallel. The end of the tooth mounting frame 28 is provided with a folded plate which is fixedly connected with the left side plate 27 and the right side plate 1 by bolts, and each tooth 2 is fixedly connected with the tooth mounting frame 28 by bolts or welding.

[0036] In this embodiment, the guiding baffle 10 is mounted on the inner side of the rear portion of both the left side plate 27 and the right side plate 1, and the guiding baffle 10 is inclined inwardly to form a narrowed discharge channel between the two guiding baffles 10. The debris such as stones moved to the rear end of the chain-link conveyor 6 passes through the discharge channel and falls on the seabed mud surface behind the integrated device. The purpose of arranging two guiding baffles 10 is to gather the debris conveyed to the rear end to the middle portion, so that the debris such as stones falling from the rear end of the chain-link conveyor 6 will not produce adverse disturbance to the rear wheel assembly, and the stability of the movement of the integrated device is ensured.

[0037] The control box 18 is mounted on the middle portion of the towing platform by the connecting side plates 23 on both sides, and the battery 21 and the controller 20 are mounted in the control box 18. The controller 20 provides the control function of the device, and the battery 21 is used to provide power, so the integrated device is a device with underwater autonomous action capability and does not depend on the control of the water surface ship equipment. As shown in Figure 1 The controller 20 is located between the upper portions of the two connecting side plates 23, and the lower edges of the two connecting side plates 23 are fixedly connected with the upper edges of the left side plate 27 and the right side plate 1 of the towing platform by bolts.

[0038] In order to ensure the water tightness of the battery 21 and the controller 20, the control box 18 is a closed box, and a charging terminal and a waterproof button switch are arranged on the control box 18. The charging terminal is used for charging the battery 21, and the waterproof button switch is used for controlling the start and stop of the device.

[0039] As shown in the figure, since the control box 18 is connected with the left side plate 27 and the right side plate 1 of the towing platform by the connecting side plates 23 on both sides, a floating channel is formed between the control box 18, the chain-link conveyor 6 and the connecting side plates 23 on both sides. The mixture dredged up by the tooth assembly is spread on the chain-link conveyor 6, and the jet flow generated by the floating tank 5 has a floating effect on the mixture, and the relatively light bottom mud and shellfish float upward to the upper portion of the floating channel and are limited below the control box 18. Since the integrated device is moved forward by dragging, the seawater moves relatively to the device from front to back and passes through the floating channel, and the passing water flow has a backward conveying effect on the light bottom mud and shellfish in the upper portion of the floating channel.

[0040] A cleaning storage tank 15 with a front inlet 22 at the front and a rear outlet 30 at the rear is installed at the rear of the control box 18, the front inlet 22 is located between the control box 18 and the chain-and-bar conveyor 6, and a filter-type rear cover 14 is installed at the rear outlet 30. A washing roller assembly is installed inside the cleaning storage tank 15, and a cleaning submersible pump 17 for supplying water into the cleaning storage tank 15 is installed on the connecting side plate 23.

[0041] The light-weight silt and shellfish moving rearward enter the cleaning storage tank 15 through the front inlet 22, the cleaning submersible pump 17 injects a high-pressure water flow into the cleaning storage tank 15, and the washing roller assembly produces a washing effect, so that the shellfish and silt are further separated and the silt is further broken up to form mud, and the mud, microorganisms, etc. on the shellfish shell are also washed off. Under the combined action of the aforementioned water flow and the water flow injected by the cleaning submersible pump 17, the mud formed in the cleaning storage tank 15 is discharged outward through the filter-type rear cover 14, and the cleaned shellfish are trapped in the cleaning storage tank 15 and are lifted to the water surface to open the filter-type rear cover 14 and remove the shellfish samples inside.

[0042] Please refer to Figure 3 and Figure 4 It can be seen that:

[0043] The cleaning storage tank 15 includes an internal front tank and an internal rear tank, the front tank is located below the control box 18, the rear tank is located behind the control box 18, the front inlet 22 is located at the front end of the front tank, the rear outlet 30 is located at the rear end of the rear tank, the washing roller assembly is installed inside the rear tank, and the roller drive machine 16 is installed on the side wall of the rear tank.

[0044] The filter-type rear cover 14 includes a rear cover cover plate with filter holes, the rear cover cover plate is hingedly connected to the upper edge of the rear outlet 30 through a hinge 31, a cover buckle 12 is installed on the outer edge of the rear cover cover plate, and a tank buckle 32 that matches the cover buckle 12 is installed on the lower edge of the rear outlet 30. In this way, when the cover buckle 12 and the tank buckle 32 are combined, the filter-type rear cover 14 is buckled on the rear outlet 30 to close the rear outlet 30, and when the cover buckle 12 and the tank buckle 32 are separated, the filter-type rear cover 14 can be opened upward to open the rear outlet 30 and remove the shellfish samples inside.

[0045] As shown in Figure 4 , the washing roller assembly includes three washing rollers 13 arranged in a triangle, the washing rollers 13 include roller bodies located in the middle, and bristles are installed on the outer walls of the roller bodies. A belt pulley is installed at the end of each roller body of the washing rollers 13, and the belt pulleys are connected by a belt, and a belt pulley is installed on the output shaft of the roller drive machine 16 and is connected to one of the belt pulleys of the washing rollers 13 by a belt.

[0046] Under the aforementioned transmission relationship, each washing roller 13 rotates synchronously. Due to the disturbance of the water flow and the disturbance of the washing roller 13 during rotation, the bottom mud and shellfish entering the cleaning storage tank 15 are floating in the cleaning storage tank 15, and thus are rolled into each washing roller 13, the washing roller 13 acts on the bottom mud and shellfish, and the bottom mud and shellfish are separated, the bottom mud is broken, and the microorganisms attached to the shellfish are separated, so as to achieve the cleaning effect. Since the washing roller 13 is provided with bristles and the shellfish shell is usually hard, the shell of the shellfish is tightly closed under the condition of continuous disturbance, so the shellfish sample will not be damaged during the cleaning process.

[0047] The cleaning submersible pump 17 is fixedly installed on the connecting side plate 23, and the water outlet thereof is embedded through the rear tank of the cleaning storage tank 15, and the cleaning submersible pump 17 injects the seawater around the device into the cleaning storage tank 15 in a pressurized manner. It is worth noting that the water flow direction injected by the cleaning submersible pump 17 into the cleaning storage tank 15 should be towards the rear outlet 30, so that the water flow injected towards the rear will not resist the water flow carrying the bottom mud and shellfish entering from the front inlet 22, and the water flow flowing towards the rear outlet 30 can also promote the water flow carrying the bottom mud and shellfish to enter the cleaning storage tank 15, that is, to generate a positive suction effect of the front inlet 22, which can promote the water flow carrying the bottom mud and shellfish in the flotation channel to enter the cleaning storage tank 15, and improve the sampling efficiency and sampling effect.

[0048] Considering that the debris on the seabed may be sucked into the cleaning submersible pump 17 to cause a blockage problem, in the embodiment, a cleaning submersible pump filter screen 19 is installed on the inlet of the cleaning submersible pump 17.

[0049] The controller 18 is constructed based on a PLC chip, the conveyor drive machine 11 of the chain conveyor belt 6, the roller drive machine 16 of the washing roller assembly, the flotation submersible pump 4 and the cleaning submersible pump 17 are connected with the controller 18, and the controller 18 controls the start and stop of the related components according to the set rules.

[0050] In the embodiment, a trigger switch 3 is installed on the front outer side of the left side plate 27 or the right side plate 1, the trigger switch 3 is connected with the controller 18, and the trigger switch 3 is pressed and triggered when the device sinks to the seabed mud surface, and the trigger switch 3 is reset when the device is separated from the seabed mud surface. The trigger switch 3 is arranged to enable the controller 18 to detect whether the device has sunk to the seabed mud surface, and if it is judged that the device has sunk to the mud surface, the conveyor drive machine 11 of the chain conveyor belt 6 can be instructed to start.

[0051] Specifically, the trigger switch 3 is a contact switch with watertight characteristics, and a ball is installed on the contact part of the trigger switch 3. When the device is settled on the seabed mud surface, the ball is in contact with the mud surface, and thus the trigger switch 3 is triggered. The ball is arranged to avoid the contact part of the trigger switch 3 being inserted into the seabed mud surface, which may cause the trigger switch 3 to fail to trigger. The trigger switch 3 is internally provided with a reset spring. When the device is separated from the seabed mud surface, the pressure applied to the ball of the trigger switch 3 disappears, and the trigger switch 3 is reset under the action of the internal reset spring.

[0052] Operation mode: the ship equipment drives to the sea area for shell sampling, and the crane equipment is used to release the hanger cable to throw the integrated device into the water. Before being thrown, the waterproof button switch on the control box 18 is triggered by the operator, at this time, the cleaning submersible pump 17 and the roller drive machine 16 are started to operate.

[0053] When the hanger cable is released to a certain length, the two rear wheel assemblies of the integrated device first fall on the seabed mud surface, and then the front part of the device is tilted downward until the front part also falls on the seabed mud surface. At this time, the trigger switch 3 is triggered under pressure, and the conveyor belt drive machine 11 and the flotation submersible pump 4 are started to operate; the ship continues to release the hanger cable to a certain length to make the hanger cable slack, and then the ship drives forward along the set path at a slow speed. As the hanger cable becomes tight, the integrated device is dragged to move behind the ship.

[0054] During the dragging movement, the integrated device moves forward along the sampling path on the seabed mud surface, and the front toothed assembly shovels the surface layer of the seabed mud, and the mixture containing the bottom mud, shells and other sundries is transferred backward to the chain link conveyor belt 6 and spread out, and is moved backward by the chain link conveyor belt 6; the flotation submersible pump 4 sends the surrounding seawater into the flotation water tank 5 in a pressurized state, and the water source is jetted upward through the water hole on the top wall of the flotation water tank 5, passes through the gap on the chain link conveyor belt 6 and acts on the spread mixture, the jet flow produces a flotation effect, and the relatively light bottom mud and shells in the mixture float upward and move to the upper part of the flotation channel (blocked by the bottom wall of the control box 18) under the action of the flotation flow, and the relatively heavy sundries such as stones are left on the chain link conveyor belt 6 and transferred backward to the rear end and finally fall off onto the seabed mud surface behind the device.

[0055] The water flow containing the bottom mud and shells in the flotation channel enters the cleaning storage tank 15 through the front inlet 22, as described above, the backward water flow generated by the cleaning submersible pump 17 can promote the water flow containing the bottom mud and shells to be sucked in through the front inlet 22, and the cleaning submersible pump 17 and the roller drive machine 16 continue to operate, the jet flow and the washing rollers 13 produce a cleaning effect on the shell samples, the bottom mud is broken, and the cleaned mud is discharged through the filter type rear cover 14 under the action of the backward water flow generated by the cleaning submersible pump 17, and the shell samples are intercepted inside.

[0056] The integrated device can be lifted after the ship travels a certain distance. Specifically, the ship crane winds up the hoisting cable. As the hoisting cable is tensioned and wound up, the front part of the integrated device first leaves the seabed mud surface. At this time, the trigger switch 3 is reset, and the controller 18 instructs the conveyor belt drive 11 and the flotation submersible pump 4 to stop running. As the hoisting cable is further tensioned and wound up, the integrated device completely separates from the seabed mud surface. During the lifting process to the water surface of the ship, the cleaning submersible pump 17 and the roller drive 16 remain running, that is, during the lifting process, the integrated device continues to perform the cleaning operation. After the device is lifted to the deck of the ship, the sampling personnel trigger the waterproof button switch, and the cleaning submersible pump 17 and the roller drive 16 stop running.

[0057] After that, the sampling personnel manually open the filter type rear cover 14 to open the rear outlet 30, and the internal shellfish samples are taken out from the rear outlet 30. At the same time, the debris in the cleaning storage tank 15 should be cleaned, and be prepared for the next use.
