Description

Technical Field

[0001] The present invention relates to the field of water environment detection, in particular to a suspended matter collection device and a suspended matter sampling system. Background Art

[0002] To collect suspended particulate matter in water, a suspended matter collection device can be used. However, the suspended matter collection device in the related art is equipped with multiple sampling cylinders for sampling, and each sampling cylinder must be equipped with a one-way valve to ensure the one-way flow of seawater. However, the setting of the one-way valve means that when the cylinder is used in deep water, the one-way valve corresponding to the working pressure needs to be replaced to adapt to the pressure at depth, which makes it less applicable. In addition, the related art uses the floating frame to float up and down to achieve the movement of the sampling cylinder in the water, which has poor collection stability. Therefore, it is necessary to study and solve this problem. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a suspended matter collection device that can increase the water flow rate of the suspended matter collection device and improve its applicability and collection stability at different water depths.

[0044] The suspended matter collecting device and the suspended matter sampling system according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 5 The suspended matter collection device 100 according to an embodiment of the present invention includes a filter membrane 230, a main body 200, and a pump 110. The filter membrane 230 is used to absorb suspended matter, thereby enabling the suspended matter collection device 100 to collect suspended matter. The main body 200 has a first hole 210 and an opening 205. The main body 200 has a set height direction. The main body 200 includes a plurality of splicing pieces 240, each of which is stacked in sequence along the height direction of the main body 200, or each of which is arranged in sequence along the circumference of the main body 200. The filter membrane 230 is sandwiched between two adjacent splicing pieces 240. The side of the splicing piece 240 that contacts the filter membrane 230 is provided with a first groove 250. One end of the first groove 250 is connected to the first hole 210, and the other end of the first groove 250 is connected to the opening 205. The pump 110 is connected to the first hole 210 and is used to suck water from the first hole 210. When the pump 110 sucks from the orifice of the first hole 210, water flows into the first trough 250 from the opening 205 and finally flows out along the first hole 210 to the pump 110. During the flow of the water, the water contacts the filter membrane 230, and the filter membrane 230 adsorbs the suspended matter in the water on the membrane, thereby realizing the collection of the suspended matter.

[0046] Compared to related art methods that use a one-way valve to control the flow direction of water, the suspended matter collection device 100 of the present invention utilizes a pump 110 to pump the water. This eliminates the need for water to overcome the resistance of the one-way valve when entering the main body 200, resulting in a greater flow rate. Furthermore, the suspended matter collection device 100 of the present invention does not need to consider the operating pressure of the one-way valve under water pressure at different depths, improving the applicability of the suspended matter collection device 100 at various water depths. Compared to methods that utilize a floating frame to move the sampling tube relative to the water surface in response to the movement of the sea surface, the embodiment of the present invention utilizes a pump 110 for pumping, making the collection of suspended matter collection device 100 more controllable and improving collection stability.

[0047] Specifically, the assembling pieces 240 can be arranged in the housing 120 and then sealed to achieve relative fixation between the assembling pieces 240. In this case, the dimensions of the housing 120 should be compatible with the dimensions of the main body 200. A gasket or elastic member can also be provided in the housing 120 to wrap and pre-tighten the main body 200. Alternatively, the assembling pieces 240 can also be fixed in relative position using fasteners, clamps, or waterproof adhesive, as long as the first hole 210 and the first slot 250 are connected.

[0048] In some embodiments of the suspended matter collecting device 100, the assembling pieces 240 are stacked sequentially along the height of the main body 200, and each assembling piece 240 is provided with a third hole 270. The through holes are interconnected, thereby defining the first hole 210. The first groove 250 has a first opening 251 and a second opening 252. The first opening 251 is provided on the wall of the third hole 270, and the second opening 252 is provided on the outer surface of the assembling piece 240 in the circumferential direction of the main body 200. The second opening 252 defines the opening 205 of the main body 200. Thus, the first groove 250 connects the first hole 210 and the opening 205, allowing water to flow from the outer circumferential surface of the main body 200 and then into the first hole 210 to be sucked by the pump 110.

[0049] It is understood that the third hole 270 on the splicing piece 240 at the end of the main body 200 away from the pump 110 can be configured as a through hole or a countersunk hole. In some embodiments of the suspended matter collection device 100, the splicing pieces 240 are arranged on the housing 120, and a spacer can be used to separate the splicing pieces 240 at the end from the bottom surface of the housing 120 by a certain distance. In this way, the filter membrane 230 is also provided at the end of the splicing piece 240 away from the pump 110. In this way, the third hole 270 on the splicing piece 240 at the end is configured as a through hole, thereby allowing part of the water to flow along the end of the main body 200 away from the pump 110, thereby utilizing the filter membrane 230 located at the end to collect suspended matter. Alternatively, the end splicing piece 240 is fitted with the bottom surface of the shell 120, and the third hole 270 of the end splicing piece 240 is set as a countersunk hole, so that water flows only from the first groove 250 on the circumference of the main body 200 into the first hole 210, reducing the height direction force exerted on the main body 200 in the shell 120.

[0050] The splicing piece 240 can be cylindrical, with the first groove 250 disposed on the axial end surface of the splicing piece 240. The first groove 250 can be disposed on both opposing axial end surfaces of the splicing piece 240, thereby increasing water flow. When the splicing pieces 240 are stacked axially, the first grooves 250 of adjacent splicing pieces 240 can be arranged opposite each other or staggered. The specific arrangement is determined by the size of the first grooves 250 and the required water flow path size.

[0051] In some embodiments of the suspended matter collecting device 100, the splicing pieces 240 are sequentially arranged along the circumference of the main body 200. Figure 5 A splicing surface 280 is provided on the side of the splicing piece 240 perpendicular to the height direction of the main body 200. When the splicing pieces 240 are arranged along the circumference of the main body 200, the splicing surfaces 280 of the splicing pieces 240 jointly define the first hole 210. The splicing pieces 240 can be configured in a triangular prism shape, with the splicing surface 280 provided at the tip of the triangular prism. The side of the splicing piece 240 facing away from the splicing surface 280 serves as one side of the circumferential outer surface of the main body 200. The first groove is provided on the side surface of the splicing piece 240 connecting the tip side and the large surface side. The first groove 250 has a first opening 251 and a second opening 252. The first opening 251 is provided on the splicing surface 280, and the second opening 252 is provided on the surface of the splicing piece 240 facing away from the splicing surface 280. The second opening 252 defines the opening 205 of the main body 200. Therefore, after the splicing pieces 240 are arranged, the first hole 210 and the opening 205 are connected through the first groove 250. When the splicing pieces 240 are arranged, the side surfaces connecting the tip side and the large surface side of each splicing piece 240 are abutted against each other. When the splicing pieces 240 are arranged in a circle along the arrangement direction, the cylindrical main body 200 is formed.

[0052] It is understood that the shapes of the splicing pieces 240 can also be set to other shapes, and the shapes of the splicing pieces 240 can be the same or different. However, ultimately, after the splicing pieces 240 are arranged along the circumferential direction, they should define the first hole 210 and be assembled into a complete body. The shape of the splicing surface 280 is also not limited and can be set to a flat surface, a curved surface that is concave inwardly of the splicing piece 240, or a curved surface that is convex inwardly of the splicing piece 240. The specific shape is determined by the shape requirements of the first hole.

[0053] Specifically, the filter membrane 230 can be a conventional 0.45 μm filter membrane 230, which is common in the art. Filter membranes 230 of different specifications can also be used depending on the target suspended matter. The pump 110 is a conventional vacuum pump 110, which can be controlled via wireless signals. It is understood that when the suspended matter collection device 100 is used in deep water environments, a timing assembly can be provided on the pump 110 to enable the pump 110 to be turned on and off at specific times, thereby achieving water extraction. The main body 200 can be made of metal, and the assembly 240 can be manufactured using conventional metalworking techniques. Alternatively, the main body 200 can be made of plastic or rubber, and the assembly 240 can be manufactured through injection molding or 3D printing. The specific shape of the main body 200 is not limited and can be cylindrical or rectangular, depending on the shape and assembly method of the assembly 240.

[0054] Further, refer to Figure 3 Based on the stacking of the assembling pieces 240 along the height direction of the main body 200, the assembling pieces 240 are provided with a plurality of first grooves 250, each of which is arranged in a circumferential direction of the main body 200. The provision of the plurality of first grooves 250 can increase the flow rate of water within the main body 200, allowing the filter membrane 230 to contact more suspended matter per unit time, thereby increasing the effective contact area between the filter membrane 230 and the water flow, improving the utilization rate of the filter membrane 230, and thereby improving the collection efficiency of the suspended matter collection device 100.

[0055] The equidistant distribution of adjacent first grooves 250 allows for a more uniform circumferential force on the main body 200 as water flows through the main body 200, thereby reducing potential deflection forces on the main body 200 and ensuring relative stability when the main body 200 is suspended in the water. Furthermore, the third holes 270 can be positioned in the middle of the joint 240 so that, after each third hole 270 defines the first hole 210, the first hole 210 is located in the middle of the main body 200. This allows for a more uniform circumferential force on the main body 200 caused by the water flow when the pump 110 is pumping water, reducing swaying of the main body 200.

[0056] Within the main body 200, the suction force increases the closer to the pump 110. When the volumes of the first grooves 250 are the same, the side closer to the pump 110 has a greater water flow rate, resulting in a better collection effect for the filter membrane 230. On the side farther from the pump 110, the water flow rate is smaller, resulting in a poorer collection effect for the filter membrane 230, and thus, the filter membranes 230 are not fully utilized to collect suspended matter. To address the above problem, as a further improvement to the above solution, the pump 110 is positioned on one side of the main body 200 in the height direction. Along the height direction of the main body 200, the volume of the first grooves 250 of each splicing element 240 increases sequentially as it moves away from the pump 110. Because the volume of the first grooves 250 on the side closer to the pump 110 is smaller, the resistance to water flow is greater. On the side farther from the pump 110, the volume of the first grooves 250 is relatively larger, resulting in less resistance to water flow. By controlling the volume of the first groove 250 of each splicing piece 240, the relationship between the suction force of the pump 110 and the resistance to water flow is balanced, so that the water flow rate at each position on the main body 200 is relatively uniform, thereby improving the utilization rate of the filter membrane 230 on the side away from the pump 110.

[0057] Similarly, refer to Figure 5 In addition to the circumferential arrangement of the splicing pieces 240, the splicing pieces 240 are provided with a plurality of first grooves 250, each of which is arranged in a sequence along the height direction of the main body 200. The provision of multiple first grooves 250 increases the flow rate of water within the main body 200, allowing the filter membrane 230 to contact more suspended matter per unit time. This increases the effective contact area between the filter membrane 230 and the water flow, improves the utilization rate of the filter membrane 230, and thereby enhances the collection efficiency of the suspended matter collection device 100.

[0058] To improve the utilization rate of the filter membrane 230 on the side away from the pump 110, the volume of each first groove 250 of the splicing piece 240 increases sequentially in the height direction of the main body 200, in the direction away from the pump 110. Because the volume of the first groove 250 on the side close to the pump 110 is smaller, the resistance to water flow is greater, while the volume of the first groove 250 on the side away from the pump 110 is relatively larger, and the resistance to water flow is smaller. By controlling the volume of the first groove 250 of each splicing piece 240, the relationship between the suction force of the pump 110 and the resistance to water flow is balanced, making the water flow rate at each position on the main body 200 relatively uniform, thereby improving the utilization rate of the filter membrane 230 on the side away from the pump 110.

[0059] Reference Figure 3 and Figure 5In addition to the plurality of first grooves 250 provided on the splicing piece 240, the splicing piece 240 is further provided with second grooves 260. The second grooves 260 communicate with adjacent first grooves 250, and each second groove 260 is arranged along the circumferential outer surface of the main body 200 in a direction close to the first hole 210. The provision of the second grooves 260 allows, when one of the first grooves 250 becomes clogged or the permeability of the permeable membrane decreases due to the accumulation of suspended matter, water can flow through the second grooves 260 to the adjacent first groove 250, thereby bypassing the clogged area of the first groove 250 and flowing back from the adjacent first groove 250 to the originally clogged first groove 250 through the other second grooves 260 near the side of the first hole 210, thereby improving the utilization rate of the filter membrane 230 at the originally clogged first groove 250.

[0060] To facilitate the relative fixation of the assembly 240 within the main body 200 and protect the main body 200, the suspended matter collection device 100 further includes a housing 120. The housing 120 is provided with a receiving chamber 123 and a first through-hole 121 and a second through-hole 122 communicating with the receiving chamber 123. The main body 200 is disposed within the receiving chamber 123. The first through-hole 121 communicates with the first hole 210, enabling the pump 110 to pump through the first hole 210. The second through-hole 122 is disposed on the circumferential outer surface of the housing 120. The second through-hole 122 provides a channel for water to flow in. After entering the housing 120 through the second through-hole 122, the water flows along the first groove 250 into the first hole 210, ultimately being sucked and discharged by the pump 110. The second through-hole 122 also serves to block large impurities, reducing the possibility of clogging of the first groove 250.

[0061] Specifically, when the pump 110 is connected to the first hole 210, airtightness should be ensured between the pump 110 and the main body 200, thereby ensuring that water is drawn from the first hole 210 rather than from the gap within the housing 120. The airtightness between the pump 110 and the main body 200 can be achieved by directly connecting the pump head through the first through-hole 121 and the opening of the first hole 210. Alternatively, the pump head 110 can be connected to the housing 120 and positioned at the opening of the first through-hole 121, thereby filling the gap between the first hole 210 and the first through-hole 121 in the height direction of the main body 200, thereby ensuring a certain degree of airtightness between the pump 110 and the main body 200.

[0062] The material of the housing 120 can be concrete or steel to ensure the strength of the housing 120. The aperture of the second through hole 122 can be set between 2 mm and 10 mm, for example, 2 mm, 4 mm, 6 mm, 8 mm, or 10 mm, or any other value between 2 mm and 10 mm. By setting the aperture of the second through hole 122 within this range, large suspended particles and debris in the water can be effectively blocked, the water entering the housing 120 can be initially filtered, and the impurities entering the housing 120 can be reduced.

[0063] As an improvement to the above solution, refer to Figure 2 The inner surface of the housing 120 is further provided with a plurality of limiting posts 124, each of which is spaced apart. The main body 200 is further provided with a plurality of second holes 220, each of which is inserted into each of the second holes 220. By inserting each of the limiting posts 124 into each of the second holes 220, the plurality of limiting posts 124 can restrict the rotational movement of the main body 200 within the housing 120, thereby improving the operating stability of the suspended matter collection device 100.

[0064] An embodiment of the present invention also provides a suspended solids collection system, comprising the suspended solids collection device 100 of the aforementioned embodiment, as well as a counterweight 300 and a buoyancy device 400. The counterweight 300 is connected to the suspended solids collection device 100 and is used to allow the suspended solids collection device 100 to sink within the water. The buoyancy device 400 is connected to the suspended solids collection device 100 and provides sufficient buoyancy for the suspended solids collection device 100, enabling it to maintain a certain depth within the water. The suspended solids collection device 100 of the embodiment of the present invention can increase the flow rate of water within the suspended solids collection system, thereby achieving high-throughput sampling. Furthermore, the suspended solids collection system can be applied to environments of varying water depths, enhancing its applicability. Furthermore, the suspended solids collection device 100 of the embodiment of the present invention utilizes a pump 110 to pump water, making the collection process more controllable and enabling long-term and fixed-point sampling within the water.

[0065] Specifically, the suspended solids collection device 100 and the counterweight 300 can be connected via an anchor chain 130 to ensure structural strength. The end of the suspended solids collection device 100 near the water surface is also connected to a recovery device outside the water surface via an anchor chain 130, ensuring structural strength while facilitating recovery. The buoyancy device 400 can be directly connected to the main body 200. In embodiments in which a housing 120 is provided, it can also be directly connected to the housing 120. Alternatively, the buoyancy device 400 can be connected to the anchor chain 130, thereby being provided separately from the suspended solids collection device 100.

[0066] It is understandable that the suspended matter collection system can include multiple suspended matter collection devices 100 and multiple buoyancy devices 400. The suspended matter collection devices 100 and the buoyancy devices 400 can be in one-to-one correspondence, or multiple buoyancy devices 400 can be provided corresponding to one suspended matter collection device 100. The suspended matter collection devices 100 are arranged along the depth direction of the water body, thereby achieving multi-point sampling in the water body. Among them, the suspended matter collection devices 100 can be connected by an anchor chain 130 to ensure the structural strength of the suspended matter collection system and facilitate the recovery of each suspended matter collection device 100. The suspended matter collection device 100 located at the shallowest part of the water body is connected to the recovery device outside the water body. Among them, the suspended matter collection device 100 located at the deepest part of the water body is directly connected to the counterweight block 300, and adjacent suspended matter collection devices 100 are connected to each other.

[0067] Furthermore, the buoyancy device 400 includes a fixing frame 420 and a plurality of floats 410. The fixing frame 420 includes a first connecting portion 430 and a second connecting portion 440 that are interconnected. The floats 410 are fixed to the first connecting portion 430. The second connecting portion 440 is fixedly connected to the suspended solids collection device 100. Each float 410 surrounds the suspended solids collection device 100 along the circumference of the main body 200. By surrounding the suspended solids collection device 100 along the circumference of the main body 200, the buoyancy force applied to the suspended solids collection device 100 is uniform, ensuring that the suspended solids collection device 100 is positioned at a predetermined height and remains stably suspended. Furthermore, since there are multiple floats 410, if one float 410 is damaged, the others can still provide buoyancy. Furthermore, since the float 410 is usually an inflatable gas tank or a floating ball, assembly is more troublesome. Therefore, the float 410 is first assembled on the fixing frame 420. Compared with directly assembling the float 410 on the suspended matter collection device 100, the operation space is larger and the difficulty is lower. Therefore, the fixing frame 420 can reduce the difficulty of assembling the float 410.

[0068] In water research, in addition to the suspended matter itself, the environmental conditions of the water body also need to be considered. To this end, embodiments of the present invention further provide a suspended matter collection system having an environmental sensor 500. Environmental sensor 500 includes at least one of a thermometer, a salinometer, or a dissolved oxygen meter, and is fixed to suspended matter collection device 100. Environmental sensor 500 detects parameters of the water body, such as temperature, salinity, or dissolved oxygen, and can record the evolution of the water environment during suspended matter sampling, facilitating scientific analysis of water and suspended matter sampling results.

[0069] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
