Description

Technical Field

[0001] The invention relates to the technical field of sorting devices, and in particular to an intelligent sorting device for large benthic invertebrates. Background Art

[0002] Benthic animals are a complex ecological group. The species and lifestyles they include are much more complicated than those of zooplankton. Most benthic animals live in bottom mud for a long time and have strong regional characteristics and weak migration ability. They usually have little ability to avoid environmental pollution and changes, and the destruction and reconstruction of their communities require a relatively long time. Most species are large and easy to identify. At the same time, different types of benthic animals have different adaptability to environmental conditions and different tolerance and sensitivity to adverse factors such as pollution. Based on the above characteristics, the use of parameters such as the population structure, dominant species, and quantity of benthic animals can accurately reflect the quality of water bodies. Therefore, there are currently sorting devices for benthic animals to monitor the condition of water bodies.

[0003] Among them, large benthic invertebrates are mainly aquatic animals visible to the naked eye that live on the bottom of the water or attached to aquatic plants and rocks. They have poor mobility, long lifespan, large body size, easy to identify, and wide distribution. In addition, large benthic invertebrates usually refer to benthic organisms with individuals larger than 0.5 mm, mainly composed of Annelida, Mollusca, Arthropoda, etc. Large benthic invertebrates are of great significance in ecology. They are important indicator organisms in water ecological monitoring and can reflect the ecological and environmental status of water bodies.

[0004] At present, the sorting process of large freshwater benthic animals is as follows: first use a mud sampler to take a unit volume of bottom mud (volume V), put it into a mud collecting tray, and then introduce it into a filter with a certain micropore, rinse it completely with tap water, wash away most of the sludge, and basically leave the benthic animals, and then introduce it into a white porcelain tray, and manually sort the benthic animals, and sort out benthic animals of different sizes and different groups from the washing tray. Finally, take it back to the laboratory for identification. Compared with the monitoring of phytoplankton and zooplankton, the monitoring of benthic animals has an additional process, namely screening. Because the range of benthic animals is very wide and each group has different living habits, manual screening is a complicated task. Therefore, an intelligent device for sorting large benthic invertebrates 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

[0045] Example:

[0046] A large benthic invertebrate intelligent sorting device, such as Figure 1-9 As shown, it includes a sorting box 100, and the box doors around the sorting box 100 can be opened, which is convenient for the staff to take out or put in, and also convenient for the inspection and maintenance of various components;

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

[0048] A cleaning and screening box 120 is provided inside the sorting box 100. The staff puts the collected sludge into the cleaning and screening box 120 for cleaning and screening, so as to facilitate the subsequent sorting thereof;

[0049] The sorting box 100 is fixedly connected to a support frame 101, and a movable guide rail 102 is mounted on the support frame 101. The movable guide rail 102 is composed of two electric slide rails, which can carry the sorting equipment to move arbitrarily in a plane, so as to facilitate the mobile support when sorting and classifying large benthic animals; a supporting connecting plate 103 is fixedly connected to the electric sliding block of the movable guide rail 102, and a rotating driving member 106 is fixedly connected to the bottom of the supporting connecting plate 103, and the output shaft of the rotating driving member 106 is connected to a rotating disk 200 through a rotating shaft. A plurality of circular notches are machined around the rotating disk 200, and a plurality of clamping assemblies are arranged in the circular notches of the rotating disk 200. It is worth mentioning that the number of circular notches is the same as the number of clamping assemblies. In the present embodiment, the preferred number is four. The rotating driving member 106 adopts a stepping motor, which has no cumulative error, a simple structure, convenient use and maintenance, low manufacturing cost, precise rotation angle, and different clamping assemblies. Different types and shapes of benthic animals can be sorted and clamped; a high-definition camera 201 is fixedly connected to the middle position of the bottom of the rotating disk 200. 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 types of benthic animals based on big data, and then sorts and classifies the benthic animals through different clamping components; a displacement drive member 105 is also fixedly connected to one side of the supporting connecting plate 103, and a telescopic control board 400 is fixedly connected to the output end of the displacement drive member 105. The telescopic control board 400 is used to drive the clamping component to move downward to complete the sorting operation. It should be noted that the displacement drive member 105 adopts an electric push rod, which is small, flexible and low in cost; a balancing load-bearing block 104 is fixedly connected to the bottom of one side of the supporting connecting plate 103 away from the rotating drive member 106. The balancing load-bearing block 104 is used to balance the gravity on both sides of the supporting connecting plate 103 to prevent more equipment on one side of the supporting connecting plate 103 from affecting the balance of the device during operation;

[0050] Furthermore, a screening plate 121 is provided inside the cleaning and screening box 120, and a vibration motor is provided outside the cleaning and screening box 120 for vibrating and screening the screening plate 121. The screening plate 121 is processed with evenly distributed screening holes, and the aperture of the screening holes is 40 meshes. A circulating water pipe 122 is also provided on the cleaning and screening box 120. The bottom of the circulating water pipe 122 is located inside the cleaning and screening box 120 and can be retracted. The top of the circulating water pipe 122 is connected to a water outlet for cleaning sediment. Floating air bags 123 are provided around the water pumping port of the circulating water pipe 122. It is worth noting that the floating air bag 123 is always located in the upper layer of the water body with the water pumping port of the circulating water pipe 122, so that the upper clear liquid of the water body is pumped out into the water outlet of the cleaning and screening box 120 through a water pump, and the sample on the screening plate 121 is cleaned again;

[0051] Furthermore, the plurality of clamping assemblies each include 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, the two translation rods 302 are rotatably connected with a rotating ring 305, the moving shaft 304 and the translation rods 302 are transmission-connected by the rotating ring 305, a locking block 303 is fixedly connected to one side of the translation rod 302, a locking hole 202 is machined at the circular notch of the rotating disk 200, the locking block 303 passes through the side hole of the displacement cylinder 300 and the locking hole 202 are fitted and fixed to each other, and the locking block 303 and the locking hole 202 need to be released. When fixing between the two, it is necessary that when the telescopic rod 301 moves toward the outside of 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 and drive the two translation rods 302 to approach each other, so that the blocking block 303 is separated from the blocking hole 202. When it is necessary to form a fixed relationship between the blocking block 303 and the blocking hole 202, when the telescopic rod 301 moves toward the inside of 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 and drive the two translation rods 302 to move away from each other, so that the blocking block 303 enters the blocking hole 202 to form a fixed relationship;

[0052] In order to realize the function of the telescopic rod 301 moving inward and outward toward the displacement cylinder 300, the present embodiment adopts the following scheme: one side of the telescopic control plate 400 is processed with an arc-shaped edge, the arc-shaped edge of the telescopic control plate 400 is processed with a notch, a telescopic electromagnetic block 401 is arranged inside the notch of the telescopic control plate 400, and a magnet is arranged outside the telescopic rod 301. By energizing the telescopic electromagnetic block 401 to form a strong magnetic force to absorb the telescopic rod 301, the telescopic electromagnetic block 401 is driven to extend and retract, so that the telescopic rod 301 can be moved toward the displacement cylinder 300. As for the function of moving in and out, it is worth noting that the center of the circle formed by the arc-shaped edge of the telescopic control plate 400 coincides with the center of the rotating disk 200, so that when the rotating disk 200 rotates with the displacement cylinder 300, the displacement cylinder 300 will not scrape the telescopic control plate 400. When the device is stationary, the central axis of the telescopic electromagnetic block 401 coincides with the central axis of the telescopic rod 301, so the telescopic rod 301 can also accurately enter the notch of the telescopic control plate 400, so that the telescopic rod 301 and the telescopic electromagnetic block 401 are accurately fitted;

[0053] Some specific solutions about the clamping part of the clamping assembly:

[0054] First, a clamping claw 310 is fixedly connected to the bottom of the translation rod 302. The material of the clamping claw 310 is 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 animals with shells 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 absorb the small stones that have not been screened out in the mud and sand to prevent 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. The bottom of the cover plate 331 is connected to a cleaning roller 332 through an elastic telescopic column. The receiving box 330 and the cover plate 331 cooperate with each other to collect active and jumping benthic animals, 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, is filled with sponges around, and is covered with rubber. The flexible clamping rod 340 is mainly used to sort and collect annelids and arthropods, and is applied to benthic animals with a certain pressure tolerance.

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

[0059] When the present embodiment is in use, the box door on one side of the sorting box 100 is opened, and the staff first adds water to the cleaning and screening box 120, and then pours the sample sediment collected by the collector into the cleaning and screening box 120, closes the box door, starts the vibration motor to vibrate and screen the screening plate 121, and starts the water pump at the same time, draws water from the upper layer of the water body at the bottom of the cleaning and screening box 120, and continues to spray water to the sediment through the water outlet of the cleaning and screening box 120 to clean it, so as to realize the recycling of water resources. In order to ensure the cleanliness of the water, the floating airbag 123 floats on the liquid surface so that the water pumping point of the circulating water pipe 122 is always located in the upper layer of the liquid surface, so as to realize the function of taking water from the upper clear liquid for cleaning when taking water;

[0060] After the cleaning and screening is completed, the mobile guide rail 102 drives the high-definition camera 201 to move to the top of 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 based on the video data and big data. The sorting and collection work is as follows:

[0061] First, collect the stones in the sorting area to prevent benthic animals from hiding at the bottom. The stepper motor works to move the clamping assembly with the suction cup 320 to the telescopic control plate 400. After the telescopic electromagnetic block 401 is energized to form a fixed relationship with the telescopic rod 301, it moves toward the inside of the telescopic control plate 400. At this time, the telescopic rod 301 moves toward 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 bring the two translation rods 302 closer to each other, so that the positioning block 303 is disengaged from the positioning hole 202, and the clamping assembly here is unfixed from the rotating disk 200. The electric push rod pushes the telescopic control plate 400 to move downward, and the suction cup 320 moves downward to absorb the stones in the sorting area, and collects the stones and puts them into the corresponding sample collection bottle 110. After the stones are collected, the electric push rod brings the telescopic control plate 400 to reset, and the clamping assembly is also reset at this time. Then, the telescopic electromagnetic block 401 is de-energized and extends outward, pushing the telescopic rod 301 into the displacement cylinder 300 for reset. During the reset process, the positioning block 303 at this location re-enters the positioning hole 202 to form a fixed relationship therewith.

[0062] Then, the mollusks are sorted and collected. The stepper motor moves the clamping assembly with the clamping claw 310 to the telescopic control board 400. The telescopic electromagnetic block 401 continues the above operation to release the clamping assembly at this location, and pushes the clamped snails and other benthic animals with shells to be collected into the corresponding sample collection bottle 110.

[0063] Then, the arthropods and annelids are sorted and collected, and the stepper motor moves the clamping assembly with the flexible clamping rod 340 to the telescopic control board 400, and the telescopic electromagnetic block 401 continues the above operation to release the clamping assembly at this location, and pushes the clamped arthropods and annelids to be sorted and collected 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.
