Description

Technical Field

[0001] The present invention relates to the technical field of sorting devices, and particularly relates to an intelligent sorting device for macrozoobenthos. Background Art

[0002] Benthic animals are a complex ecological group. The species they include and their lifestyles are much more complex than those of zooplankton. Most benthic animals live in the sediment for a long time, with characteristics such as strong regionality and weak migration ability. They usually have little ability to avoid environmental pollution and changes. The destruction and reconstruction of their communities require a relatively long time. Moreover, most species are relatively large in size and are easy to identify. At the same time, different species of benthic animals have different adaptabilities to environmental conditions, tolerances to adverse factors such as pollution, and sensitivities. According to the above characteristics, the population structure, dominant species, quantity and other parameters of benthic animals can accurately reflect the water quality status. Therefore, there are currently sorting devices for benthic animals to monitor the water condition.

[0003] Among them, macrozoobenthos mainly refers to aquatic animals visible to the naked eye that inhabit the bottom of the water or attach to aquatic plants and stones in the water. They have poor mobility, long lifespans, relatively large sizes, are easy to identify, and are widely distributed. In addition, macrozoobenthos usually refers to benthic organisms with an individual size greater than 0.5 mm, mainly composed of Annelida, Mollusca, Arthropoda, etc. Macrozoobenthos has important significance in ecology. They are important indicator organisms in water ecological monitoring and can reflect the ecological environment status of water bodies.

[0004] The current sorting process for freshwater macrozoobenthos is as follows: First, a sediment sampler is used to take a unit volume of sediment (volume V), which is placed in a sediment collection tray and then introduced into a filter screen with a certain micropore size. After being completely rinsed with tap water, most of the sludge is washed away, and basically only benthic animals remain. Then it is introduced into a white porcelain tray, and the sorting work of benthic animals is carried out manually. Benthic animals of different sizes and different groups are sorted out from the washing tray. Finally, they are taken back to the laboratory for identification. The monitoring of benthic animals adds an extra process compared to the monitoring of phytoplankton and zooplankton, that is, screening. Also, because the scope of benthic animals is very wide and the living habits of each group are different, manual screening is a complicated task. Therefore, a device for intelligently sorting macrozoobenthos is needed.

[0005] After searching, the Chinese patent application number 201610262329.4 discloses a field collection, screening and washing device for large freshwater benthic invertebrates, including a collection box with a grab bucket at the bottom, which is connected from top to bottom and consists of an outer frame and side mesh panels, wherein a spiral blade is provided at the upper end of the collection box, a square frame is slidably provided inside the collection box, a watertight corrugated curtain is provided above the edge of the square frame, and a support device for suspending the square frame above the soil is provided below the square frame. The above patent has the following shortcomings: it can only clean and screen large benthic animals, but cannot sort benthic animals by species.

[0006] In order to intelligently sort large benthic animals, we propose an intelligent sorting device for large benthic invertebrates. Summary of the invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides an intelligent sorting device for large benthic invertebrates.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The invention provides a large-scale benthic invertebrate intelligent sorting device, comprising a sorting box, a plurality of sample collection bottles inside the sorting box, and a cleaning and screening box arranged inside the sorting box; a support frame is fixedly connected inside the sorting box, and a movable guide rail is arranged on the support frame; a supporting connecting plate is fixedly connected to an electric slider of the movable guide rail, a rotating driving member is fixedly connected to the bottom of the supporting connecting plate, an output shaft of the rotating driving member is connected to a rotating disk through a rotating shaft, a plurality of circular notches are processed around the rotating disk, and a plurality of clamping components are arranged in the circular notches of the rotating disk; a high-definition camera is fixedly connected to the middle position of the bottom of the rotating disk, and the high-definition camera records a sorting area in real time and uploads the real-time data to a terminal; a displacement driving member is also fixedly connected to one side of the supporting connecting plate, and a telescopic control board is fixedly connected to the output end of the displacement driving member, and the telescopic control board is used to drive the clamping component to move downward to complete the sorting operation.

[0010] Furthermore, multiple clamping assemblies include a displacement cylinder, a telescopic rod that moves in the displacement cylinder hole, a moving shaft that moves up and down inside the displacement cylinder, and two translation rods that move left and right inside the displacement cylinder; the telescopic rod and the moving shaft are connected by a rotating shaft, and the two translation rods are rotatably connected with a rotating ring, and the moving shaft and the translation rod are transmission connected by the rotating ring; a locking block is fixedly connected to one side of the translation rod, and a locking hole is processed at the circular notch of the rotating disk, and the locking block passes through the side hole of the displacement cylinder and the locking hole to fit and fix each other.

[0011] Further, when releasing the fixation between the clamping block and the clamping hole, the telescopic rod moves outward from the displacement cylinder. The rotating shaft between the telescopic rod and the moving shaft drives the moving shaft to move upward, causing the rotating rings on both sides of the moving shaft to rotate and drive the two translation rods to approach each other, thereby disengaging the clamping block from the clamping hole. When a fixed relationship is formed between the clamping block and the clamping hole, the telescopic rod moves into the displacement cylinder. The rotating shaft between the telescopic rod and the moving shaft drives the moving shaft to move downward, causing the rotating rings on both sides of the moving shaft to rotate and drive the two translation rods to move away from each other.

[0012] Further, one side of the telescopic control plate is processed with an arc edge. A notch is processed on the arc edge of the telescopic control plate, and a telescopic electromagnet is arranged inside the notch of the telescopic control plate. A magnet that attracts the telescopic electromagnet is arranged outside the telescopic rod.

[0013] Further, the center of the circle formed by the extension of the arc edge of the telescopic control plate coincides with the center of the rotating disk.

[0014] Still further, a clamping claw is fixedly connected to the bottom of the translation rod. The clamping claw is used to clamp mollusks among benthic animals. The outer contour of the clamping claw is arc-shaped.

[0015] Still further, a suction cup is fixedly connected to the bottom of the displacement cylinder. The suction cup is used to adsorb small stones that have not been screened out in the sediment.

[0016] Still further, a receiving box is fixedly connected to the bottom of one translation rod, and a cover plate is fixedly connected to the bottom of the other translation rod. The cover plate is used to close the receiving box. A cleaning roller is connected to the bottom of the cover plate through an elastic telescopic column. The receiving box and the cover plate cooperate with each other to collect benthic animals with greater vitality.

[0017] Still further, a flexible clamping rod is fixedly connected to the bottom of the translation rod. The flexible clamping rod is supported by a wooden stick, filled with sponge around, and sleeved with rubber on the outside. The flexible clamping rod is used to clamp annelids and arthropods.

[0018] Even further, a screening disk is arranged inside the cleaning and screening box. A vibration motor is arranged outside the cleaning and screening box to perform vibration screening on the screening disk. Uniformly distributed screening holes are processed on the screening disk. A circulating water pipe is also arranged on the cleaning and screening box. The bottom of the circulating water pipe can be telescopic inside the cleaning and screening box. The top of the circulating water pipe is connected to the water outlet for cleaning the sediment. Floating air bags are arranged around the water pumping port of the circulating water pipe. The floating air bags are used to keep the water pumping port of the circulating water pipe always at the upper layer of the water body. A balance weight is fixedly connected to the bottom of the side of the support connecting plate away from the rotation driving part. The balance weight is used to balance the gravity on both sides of the support connecting plate.

[0019] Beneficial effects

[0020] The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies:

[0021] The high-definition camera can record the sorting area in real time and upload the real-time data to the terminal. The AI system of the terminal identifies different types of benthic animals based on big data, and then sorts and classifies the benthic animals through different clamping components;

[0022] A magnet is arranged outside the telescopic rod. By energizing the telescopic electromagnet, a strong magnetic force is formed to adsorb the telescopic rod, and then driving the telescopic movement of the telescopic electromagnet can realize the function of the telescopic rod moving in and out of the displacement cylinder; the telescopic rod moving in and out of the displacement cylinder can realize the release of the fixation between the clamping component and the rotating disk, and can also realize the clamping action of the clamping component, eliminating the need for an additional robotic arm device to perform the clamping operation and expanding the application range of the device;

[0023] Multiple clamping components, namely stainless steel clamping claws, suction cups, flexible clamping rods, and a containing box and a cover plate, realize the classified clamping operation of different types of benthic animals and other substances, improving the practicality of the device;

[0024] The floating airbag keeps the water intake of the circulating water pipe always at the upper layer of the water body, so as to pump out the upper clear liquid of the water body through the water pump and into the water outlet hole of the cleaning and screening box, and clean the samples on the screening disk again.

[0045] Embodiment:

[0046] A large benthic invertebrate intelligent sorting device, as Figures 1-9 shown, includes a sorting box body 100. The box doors around the sorting box body 100 can all be opened, which is convenient for the staff to take or send things in and out, and at the same time is convenient for the maintenance of each component;

[0047] A plurality of sample collection bottles 110 inside the sorting box body 100 are used to collect different types of large benthic animals, which can be basically classified into three categories, namely annelids, mollusks and arthropods;

[0048] A cleaning and screening box 120 is arranged inside the sorting box body 100. The staff puts the collected sediment into the cleaning and screening box 120 for cleaning and screening, which is convenient for subsequent sorting;

[0049] Inside the sorting box body 100, there is a fixedly connected support frame 101. On the support frame 101, there is a movable guide rail 102. The movable guide rail 102 is composed of two electric slide rails, which can drive the sorting equipment to move arbitrarily in the plane, facilitating the movable support during the sorting and classification of macrozoobenthos; on the electric slider of the movable guide rail 102, there is a fixedly connected support connecting plate 103. At the bottom of the support connecting plate 103, there is a fixedly connected rotation driving part 106. The output shaft of the rotation driving part 106 is connected to a rotating disk 200 through a rotating shaft. There are multiple circular notches processed around the rotating disk 200. Multiple clamping components are arranged in the circular notches of the rotating disk 200. It should be noted that the number of circular notches is the same as the number of clamping components. In this embodiment, the preferred number is four. The rotation driving part 106 uses a stepping motor. The stepping motor has no cumulative error, has a simple structure, is convenient to use and maintain, has a low manufacturing cost, and has a precise rotation angle. The multiple clamping components are different from each other and are used for sorting and clamping macrozoobenthos of different species and different shapes; at the middle position of the bottom of the rotating disk 200, there is a fixedly connected high-definition camera 201. The high-definition camera 201 can record the sorting area in real time and upload the real-time data to the terminal. The AI system of the terminal identifies different species of macrozoobenthos according to big data, and then sorts and classifies the macrozoobenthos through different clamping components; on one side of the support connecting plate 103, there is also a fixedly connected displacement driving part 105. The output end of the displacement driving part 105 is fixedly connected to a telescopic control plate 400. The telescopic control plate 400 is used to drive the clamping component to move down to complete the sorting operation. It should be noted that the displacement driving part 105 uses an electric push rod, which is small, flexible and has a low cost; at the bottom of the side of the support connecting plate 103 far from the rotation driving part 106, there is a fixedly connected balance load block 104. The balance load block 104 is used to balance the gravity on both sides of the support connecting plate 103 to prevent the equipment on one side of the support connecting plate 103 from being too much and affecting the balance of the device during operation;

[0050] Further, a screening disk 121 is arranged inside the cleaning and screening box 120. Outside the cleaning and screening box 120, there is a vibration motor for vibrating and screening the screening disk 121. Uniformly distributed screening holes are processed on the screening disk 121. The aperture of the screening holes is 40 mesh. A circulating water pipe 122 is also arranged on the cleaning and screening box 120. The bottom of the circulating water pipe 122 can be telescopic inside the cleaning and screening box 120. The top of the circulating water pipe 122 is connected to a water outlet for cleaning sediment. Floating air bags 123 are arranged around the water pumping port of the circulating water pipe 122. It should be noted that the floating air bags 123 keep the water pumping port of the circulating water pipe 122 always at the upper layer of the water body, so as to pump the upper clear liquid of the water body into the water outlet holes of the cleaning and screening box 120 through a water pump to clean the samples on the screening disk 121 again;

[0051] Furthermore, each of the plurality of clamping components includes a displacement cylinder 300, a telescopic rod 301 that moves in the hole of the displacement cylinder 300, a moving shaft 304 that moves up and down inside the displacement cylinder 300, and two translation rods 302 that move left and right inside the displacement cylinder 300. The telescopic rod 301 and the moving shaft 304 are connected by a rotating shaft. Rotating rings 305 are rotatably connected to both of the two translation rods 302. The moving shaft 304 and the translation rods 302 are drivingly connected through the rotating rings 305. A clamping block 303 is fixedly connected to one side of the translation rod 302. A clamping hole 202 is machined at the circular notch of the rotating disk 200. The clamping block 303 passes through the side hole of the displacement cylinder 300 and fits with the clamping hole 202 for fixation. When it is necessary to release the fixation between the clamping block 303 and the clamping hole 202, when the telescopic rod 301 moves outward from the displacement cylinder 300, the rotating shaft between the telescopic rod 301 and the moving shaft 304 drives the moving shaft 304 to move upward, so that the rotating rings 305 on both sides of the moving shaft 304 rotate to drive the two translation rods 302 to approach each other, thereby making the clamping block 303 disengage from the clamping hole 202. When it is necessary to form a fixed relationship between the clamping block 303 and the clamping hole 202, when the telescopic rod 301 moves inward into the displacement cylinder 300; the rotating shaft between the telescopic rod 301 and the moving shaft 304 drives the moving shaft 304 to move downward, so that the rotating rings 305 on both sides of the moving shaft 304 rotate to drive the two translation rods 302 to move away from each other, thereby making the clamping block 303 enter the clamping hole 202 to form a fixed relationship;

[0052] In order to realize the function of the telescopic rod 301 moving in and out of the displacement cylinder 300, the following solution is adopted in this embodiment: One side of the telescopic control board 400 is machined with an arc edge. A notch is machined on the arc edge of the telescopic control board 400. A telescopic electromagnet 401 is arranged inside the notch of the telescopic control board 400. A magnet is arranged outside the telescopic rod 301. By energizing the telescopic electromagnet 401 to form a strong magnetic force to adsorb the telescopic rod 301, and then driving the telescopic movement of the telescopic electromagnet 401, the function of the telescopic rod 301 moving in and out of the displacement cylinder 300 can be realized. It should be noted that the center of the circle formed by the extension of the arc edge of the telescopic control board 400 coincides with the center of the rotating disk 200. Thus, when the rotating disk 200 drives the displacement cylinder 300 to rotate, the displacement cylinder 300 will not rub against the telescopic control board 400. When the device is stationary, the central axis of the telescopic electromagnet 401 coincides with the central axis of the telescopic rod 301. Therefore, the telescopic rod 301 can also accurately enter the notch of the telescopic control board 400, so that the telescopic rod 301 and the telescopic electromagnet 401 are accurately fitted;

[0053] Some specific solutions regarding the clamping part of the clamping component:

[0054] First, a clamping claw 310 is fixedly connected to the bottom of the translation rod 302. The clamping claw 310 is made of stainless steel. The outer contour of the clamping claw 310 is arc-shaped. The clamping claw 310 is mainly used to clamp mollusks among benthic animals, mainly shelled animals such as snails and clams, and can withstand a certain amount of pressure.

[0055] Second, a suction cup 320 is fixedly connected to the bottom of the displacement cylinder 300. The suction cup 320 is mainly used to adsorb small stones that have not been screened out in the sediment, preventing benthic animals from hiding under the stones.

[0056] Third, a receiving box 330 is fixedly connected to the bottom of one translation rod 302, and a cover plate 331 is fixedly connected to the bottom of the other translation rod 302. The cover plate 331 is used to close the receiving box 330. A cleaning roller 332 is connected to the bottom of the cover plate 331 through an elastic telescopic column. The receiving box 330 and the cover plate 331 cooperate with each other to collect benthic animals with strong vitality that jump around, such as shrimps.

[0057] Fourth, a flexible clamping rod 340 is fixedly connected to the bottom of the translation rod 302. The flexible clamping rod 340 is supported by a wooden stick, filled with sponge around, and covered with rubber outside. The flexible clamping rod 340 is mainly used to sort and collect annelids and arthropods, and is applied to benthic animals that can withstand a certain amount of pressure.

[0058] The clamping action of the above clamping components (except for the second solution) is also completed by the two translation rods 302 approaching each other.

[0059] When this embodiment is in use, open the side door of the sorting box body 100. The staff first adds water to the cleaning and screening box 120, then pours the sample sediment collected by the collector into the cleaning and screening box 120, closes the door, starts the vibration motor to vibrate the screening plate 121 for screening, and at the same time starts the water pump to pump water from the upper layer of the water body at the bottom of the cleaning and screening box 120 through the water outlet holes of the cleaning and screening box 120 to spray water on the sediment for cleaning, realizing the recycling of water resources. To ensure the cleanliness of the water used, the floating airbag 123 floats on the liquid surface so that the water intake of the circulating water pipe 122 is always located in the upper layer of the liquid surface, realizing the function of taking water from the upper clear liquid for cleaning when taking water.

[0060] After the cleaning and screening are completed, the moving guide rail 102 drives the high-definition camera 201 to move above the cleaning and screening box 120. The high-definition camera 201 records the sorting area on the screening plate 121 and uploads the data to the terminal. The terminal identifies the benthic animals according to the video data and big data. The sorting and collection work is as follows:

[0061] First, collect the pebbles in the sorting area to prevent benthic animals from hiding under them. The stepper motor operates to move the clamping component with the suction cup 320 to the telescopic control board 400. After the telescopic electromagnet 401 is energized to form a fixed relationship with the telescopic rod 301, it moves towards the inside of the telescopic control board 400. At this time, the telescopic rod 301 moves towards the outside of the displacement cylinder 300. Driven by the rotating shaft, the moving shaft 304 moves upward, thereby driving the rotating ring 305 to rotate and bringing the two translation rods 302 closer to each other, causing the clamping block 303 to disengage from the clamping hole 202. Here, the clamping component is disengaged from the fixed relationship with the rotating disk 200 and instead forms a fixed relationship with the telescopic control board 400 through the electromagnet. At this time, the electric push rod pushes the telescopic control board 400 downward, so the suction cup 320 moves downward to adsorb the pebbles in the sorting area and collect the pebbles into the corresponding sample collection bottle 110. After the pebbles are collected, the electric push rod drives the telescopic control board 400 to reset. At this time, the clamping component also resets. Then, the telescopic electromagnet 401 is de-energized and extends outward to push the telescopic rod 301 into the displacement cylinder 300 for reset. During the reset process, the clamping block 303 re-enters the clamping hole 202 to form a fixed relationship with it;

[0062] Next, sort and collect the mollusks. The stepper motor rotates the clamping component with the clamping claw 310 to the telescopic control board 400. The telescopic electromagnet 401 continues the above operation to release the fixation of the clamping component at this location and push it to collect the shelled benthic animals such as snails into the corresponding sample collection bottle 110;

[0063] Then, sort and collect the arthropods and annelids. The stepper motor rotates the clamping component with the flexible clamping rod 340 to the telescopic control board 400. The telescopic electromagnet 401 continues the above operation to release the fixation of the clamping component at this location and push it to sort and collect the arthropods and annelids into different sample collection bottles 110;

[0064] Finally, only the more vigorous benthic organisms are left in the sorting area, and the motor moves the clamping assembly with the containing box 330 to the telescopic control plate 400, and the telescopic electromagnetic block 401 continues the above operation to release the clamping assembly at this location, and the electric push rod drives it to move downward. During the downward movement, the telescopic electromagnetic block 401 pushes outward, causing the telescopic rod 301 to move toward the inside of the displacement cylinder 300, thereby causing the two translation rods 302 to move away from each other, leaving space between the containing box 330 and the cover plate 331, and placing the more vigorous benthic animals between the containing box 330 and the cover plate 331. Then the telescopic electromagnetic block 401 quickly moves inward, driving the telescopic rod 301 to move toward the outside of the displacement cylinder 300. At this time, the two translation rods 302 approach each other, that is, the containing box 330 and the cover plate 331 quickly approach each other, and the benthic animals with strong vitality are blocked into the containing box 330. The cleaning roller 332 can sweep the benthic animals at the bottom to ensure that they can enter the containing box 330 for sorting and collection, and the collected benthic animals are sent to the corresponding sample collection bottle 110, and then the previous operation is repeated to fix the clamping assembly on the rotating disk 200;

[0065] After the sorting and collection is completed, the staff opens the box door and checks whether there are any missed benthic animals on the screening plate 121. If so, they are manually sorted. If not, the mud and sand at the bottom of the screening box 120 are cleaned and washed, and then the benthic animals in the sample collection bottle 110 are sent to the laboratory for testing.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
