Description

Technical Field

[0001] This utility model relates to the field of unmanned surface vessel (USV) sampling technology, specifically a pre-filtration device for an USV sampling mechanism. Background Technology

[0002] With the development and utilization of marine resources and the increasing prominence of global environmental issues, the importance of marine environmental monitoring is constantly rising. Unmanned surface vessels (USVs) are equipped with various sensors and sampling mechanisms, enabling comprehensive monitoring of multiple parameters such as marine hydrology, meteorology, water quality, and biology. However, the marine environment is complex and changeable. Impurities such as sediment, suspended solids, and biological debris in seawater can contaminate and clog sensors and sampling mechanisms, affecting the accuracy of monitoring data and the stability of equipment.

[0003] Chinese Patent CN213313554U discloses a pre-filtration device for a hydrological surveying unmanned surface vessel (USV) sampling mechanism. This device includes a protective shell, fixed supports, a filter cartridge, a limiting plate, a sealing cover, a water inlet pipe, and a drainage pipe. The fixed supports support the protective shell, facilitating sealing with the sealing cover. The water inlet pipe allows for the introduction of sample water into the shell, and the filter cartridge performs preliminary filtration, removing impurities. The drainage pipe then allows for sampling of the filtered water, facilitating the inspection of the sample water and its impurities by personnel.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, when removing the filter cartridge, workers need to manually disassemble the sealing cover first, which increases the complexity of the operation. Then, workers must reach into the protective housing to remove the filter cartridge. The entire process is not only time-consuming and labor-intensive but also significantly reduces the efficiency of impurity removal, causing inconvenience. Therefore, it is necessary to provide a pre-filtration device for an unmanned surface vessel sampling mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a pre-filtering device for an unmanned surface vessel sampling mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pre-filtration device for an unmanned surface vessel sampling mechanism, comprising:

[0008] The sampling box has symmetrically distributed support legs fixedly installed on both sides of its bottom. A vertical plate is fixedly installed on one side of the sampling box. A vertical slide is provided on the side of the vertical plate near the sampling box. A threaded rod is rotatably installed inside the vertical slide. A motor is fixedly installed on the top of the vertical plate. The drive end of the motor passes through the top of the vertical plate and extends into the interior of the vertical slide, where it is fixedly connected to the top of the threaded rod. A movable block is fitted on the outer wall of the threaded rod and slides within the vertical slide.

[0009] A sealing cover is fixedly installed on the side of the movable block near the sampling box, and the sealing cover is located above the top of the sampling box. A sampling mechanism is provided on the top of the sealing cover, and several fixing cylinders are fixedly installed on the bottom of the sealing cover. A U-shaped fixing frame is provided at the bottom end of the fixing cylinder.

[0010] A filter screen is fixedly installed at the bottom opening of the U-shaped fixing frame, and a drain pipe is fixedly installed at the bottom of the sampling box, with a valve on the drain pipe.

[0011] Preferably, a movable rod is slidably inserted into the bottom end of the fixed cylinder, and the bottom end of the movable rod is fixedly connected to the top of the U-shaped fixed frame. A spring is fixedly connected between the top end of the movable rod and the top of the inner wall of the fixed cylinder. A slider is fixedly installed on the outer wall of the top end of the movable rod. A groove is opened on the inner wall of the fixed cylinder, and the slider is slidably installed in the groove.

[0012] Preferably, the sampling assembly includes a conduit, which is fixedly inserted and installed on the top of the sealing cover. A pump body is provided on the conduit and is fixedly connected to the top of the sealing cover. A fixing block is fixedly installed on the other side of the sampling box. An external sampling pipe is fixedly installed on the fixing block. A connecting pipe is fixedly connected between the top end of the external sampling pipe and the top end of the conduit.

[0013] Preferably, a spiral-shaped limiting frame is fixedly installed on the upper part of the sampling box.

[0014] Preferably, the filter screen is in the shape of a hollow hemisphere and is made of a soft material.

[0015] Preferably, the movable block has a threaded hole that matches the threaded rod, and the movable block is threadedly connected to the threaded rod through the threaded hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a sampling box, supporting legs, a fixing block, an external sampling pipe, a U-shaped fixing frame, a connecting pipe, a sealing cover, a conduit, a pump body, a motor, a movable block, a vertical plate, a vertical slide rail, a threaded rod, a filter screen, and a drain pipe. During operation, the sealing cover is mechanically opened and closed. The movement of the sealing cover, via the movable rod and fixing cylinder, moves the U-shaped fixing frame and the filter screen, allowing the filter screen to move in and out in sync with the opening and closing of the sealing cover. This fully automates the filter screen handling, eliminating the need for manual disassembly and assembly of any components. The entire operation is not only time-saving and labor-saving but also significantly improves the efficiency of impurity removal, making the device extremely convenient to use.

[0018] 2. This utility model utilizes the coordinated use of a movable rod, a fixed cylinder, a U-shaped limiting frame, a spring, a sliding groove, and a slider. When the filter screen is used inside the sampling chamber, it is confined to the top of the U-shaped limiting frame by the U-shaped fixing frame. With the sealing cover closed, the movable rod retracts into the fixed cylinder, and the spring compresses it. During sampling, the sealing cover moves upward, and the filter screen moves outward accordingly. The U-shaped fixing frame loses its limiting position, and the spring causes the movable rod to extend, increasing the distance between the U-shaped fixing frame and the sealing cover, providing ample operating space for easy material retrieval. When the filter screen is moved back into the sampling chamber, the U-shaped limiting frame locks in place, causing the movable rod to retract, ensuring accurate filter screen installation and improving operational convenience and sampling efficiency.

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] A pre-filtration device for an unmanned surface vessel sampling mechanism, comprising:

[0030] The sampling box 1 has symmetrically distributed support legs 2 fixedly installed on both sides of the bottom of the sampling box 1. A vertical plate 14 is fixedly installed on one side of the sampling box 1. A vertical slide 15 is opened on the side of the vertical plate 14 near the sampling box 1. A threaded rod 16 is rotatably installed inside the vertical slide 15. A motor 12 is fixedly installed on the top of the vertical plate 14. The drive end of the motor 12 passes through the top of the vertical plate 14 and extends into the interior of the vertical slide 15 and is fixedly connected to the top of the threaded rod 16. A movable block 13 is sleeved on the outer wall of the threaded rod 16 and is slidably installed in the vertical slide 15.

[0031] A sealing cover plate 9 is fixedly installed on the side of the movable block 13 near the sampling box 1, and the sealing cover plate 9 is located above the top of the sampling box 1. A sampling mechanism is provided on the top of the sealing cover plate 9, and several fixing cylinders 7 are fixedly installed on the bottom of the sealing cover plate 9. A U-shaped fixing frame 5 is provided at the bottom of the fixing cylinder 7.

[0032] A filter screen 17 is fixedly installed at the bottom opening of the U-shaped fixed frame 5, and a drain pipe 18 is fixedly installed at the bottom of the sampling box 1, with a valve on the drain pipe 18.

[0033] A movable rod 6 is slidably inserted into the bottom end of the fixed cylinder 7, and the bottom end of the movable rod 6 is fixedly connected to the top of the U-shaped fixed frame 5. A spring 20 is fixedly connected between the top end of the movable rod 6 and the top of the inner wall of the fixed cylinder 7. A slider 22 is fixedly installed on the outer wall of the top end of the movable rod 6. A groove 21 is opened on the inner wall of the fixed cylinder 7, and the slider 22 is slidably installed in the groove 21.

[0034] In one embodiment, the sampling assembly includes a conduit 10, which is fixedly inserted into the top of the sealing cover 9. A pump body 11 is provided on the conduit 10 and is fixedly connected to the top of the sealing cover 9. A fixing block 3 is fixedly installed on the other side of the sampling box 1. A sampling external pipe 4 is fixedly installed on the fixing block 3. A connecting pipe 8 is fixedly connected between the top end of the sampling external pipe 4 and the top end of the conduit 10 to facilitate sampling by connecting an external sampling pipe.

[0035] In one preferred embodiment, a loop-shaped limiting frame 19 is fixedly installed on the upper part of the sampling box 1. The loop-shaped limiting frame 19 locks the loop-shaped fixing frame 5 to ensure the accuracy of the installation position of the filter screen 17 inside the sampling box 1.

[0036] In one embodiment, the filter screen 17 is a hollow hemispherical shape and is made of soft material. The hollow hemispherical structure increases the surface area of ​​the filter screen 17 and improves the filtration efficiency. The soft material of the filter screen 17 makes it easy to change its shape and flip it over to pick up the material.

[0037] In one preferred embodiment, the movable block 13 has a threaded hole adapted to the threaded rod 16, and the movable block 13 is threadedly connected to the threaded rod 16 through the threaded hole.

[0038] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as or can be implemented using existing technology. In use, the sampling external pipe 4 is connected to the sampling pipeline on the unmanned vessel. When the unmanned vessel reaches the designated water area, the control pump 11 starts to work. The pump 11, through the passage formed by the conduit 10, connecting pipe 8 and sampling external pipe 4, cooperates with the external sampling pipeline to pump water into the sampling box 1. After entering the sampling box 1, the water first enters the filter screen 17. The filter screen 17 filters the sampled water, trapping impurities in the water inside the filter screen 17. The filtered water is stored at the bottom inside the sampling box 1. After sampling is completed, the unmanned vessel is controlled to return. Next, the sample water and sample from the device are collected. Impurities in the water are removed for testing. The sample water can be discharged directly through the drain pipe 18. For impurities filtered out inside the filter screen 17, the motor 12 can be started. The drive end of the motor 12 drives the threaded rod 16 to rotate. Through the threaded transmission between the threaded rod 16 and the movable block 13, and the sliding relationship between the movable block 13 and the vertical slide rail 15, the movable block 13 can move vertically stably. The movement of the movable block 13 drives the sealing cover 9 to move. The movement of the sealing cover 9 drives the U-shaped fixed frame 5 to move through the fixed cylinder 7 and the movable rod 6. The filter screen 17 moves with the U-shaped fixed frame 5. When the sealing cover 9 moves upward, it loses its sealing effect on the top opening of the sampling box 1. At the same time, the filter screen 17 will move out from the top opening of the sampling box 1. Because the filter screen 17 is made of soft material, the staff can directly push the filter screen 17 upward from the center opening of the U-shaped fixed frame 5, which can easily turn out the impurities inside the filter screen 17 and complete the material collection work.

[0039] During use, the filter screen 17 is positioned inside the sampling chamber 1 by the U-shaped fixing frame 5, which limits its movement to the top of the U-shaped limiting frame 19. Because the U-shaped limiting frame 19 blocks the position of the U-shaped fixing frame 5 inside the sampling chamber 1, when the sealing cover 9 is closed, the movable rod 6 automatically retracts into the fixed cylinder 7, compressing the spring 20. When sampling is required, the sealing cover 9 moves upward, removing the filter screen 17 along with it from the sampling chamber 1. During this process, the U-shaped fixing frame 5 loses its limiting function. At this time, under the elastic action of the spring 20, the movable rod 6 automatically extends, increasing the distance between the U-shaped fixing frame 5 and the sealing cover 9. This provides sufficient operating space for the operator during material handling, making the material handling operation more convenient. During the process of the filter screen 17 being moved back into the sampling box 1, the movable rod 6 will automatically retract into the fixed cylinder 7 due to the locking action of the loop-shaped limiting frame 19 on the loop-shaped fixing frame 5, ensuring the accuracy of the installation position of the filter screen 17 inside the sampling box 1.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
