Description

Technical Field

[0001] This utility model relates to the technical field of sediment collection devices, and in particular to a sediment collection device for lake and wetland surveys. Background Technology

[0002] Sediment collection in lake and wetland surveys is a crucial step in understanding the aquatic ecosystem, pollution status, and sediment characteristics. Sediment collection devices are used to collect sediments from the bottom of lakes, wetlands, and other water bodies. Selecting appropriate sediment collection devices can ensure the representativeness and accuracy of the samples.

[0003] Existing sediment collection devices use a push rod and a disc to expel air from the collection tube and block water flow into the tube to ensure the integrity of the collected sediment. During collection, the push rod must be manually pressed until the collection tube contacts the sediment to prevent water from entering. This process is cumbersome and laborious. Therefore, this paper proposes a sediment collection device for lake and wetland surveys to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a sediment collection device for lake and wetland surveys, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sediment collection device for lake and wetland surveys, comprising: A collection tube, wherein a disc is slidably installed inside the collection tube; A propulsion unit, which is fixedly installed at one end of the collection tube; The moving mechanism is slidably connected to the collection tube and the propulsion unit, and is fixedly connected to the top of the disk. The moving mechanism is used to drive the disk to move. A fixing mechanism is provided on the top of the propulsion unit. The fixing mechanism includes a moving part and a locking part. The locking part is interlocked with the moving mechanism and is used to fix the moving mechanism. The moving part is provided on the top of the propulsion unit and is used to push the locking part to move.

[0006] Preferably, the moving mechanism includes: A push rod, one end of which is fixedly connected to a disc, and the other end of which is slidably connected to a collection tube and a propulsion unit; A push handle, one end of which is fixedly connected to the end of the push rod away from the disk, and the end of the push handle away from the push rod is inserted and connected to the locking part.

[0007] Preferably, the locking part includes a locking block, one end of which is slidably connected to the push handle, and the other end of which is fixedly connected to the moving part.

[0008] Preferably, the moving part includes: Mounting plates, multiple mounting plates are symmetrically and fixedly installed on the top of the propulsion unit; A sliding rod is disposed between multiple mounting plates, and both ends of the sliding rod are fixedly connected to one end of each mounting plate that is close to the other. A movable rod, which is slidably sleeved on the outer wall of a sliding rod, and one end of the movable rod is fixedly connected to a locking block; A pull rod, one end of which is fixedly connected to the top of a movable rod.

[0009] Preferably, a spring is sleeved on the outer wall of the sliding rod, one end of the spring is fixedly connected to one of the mounting plates, and the other end of the spring is fixedly connected to the end of the moving rod away from the locking block.

[0010] Preferably, a sealing ring is fixedly installed on the outer wall of the disc, and the sealing ring is slidably connected to the inner wall of the collection cylinder.

[0011] Preferably, a fixing frame is threaded onto the end of the collection tube away from the propulsion unit, and multiple limiting blocks are fixedly installed inside the fixing frame, with the multiple limiting blocks arranged in a circle.

[0012] The technical effects and advantages of this utility model are as follows: This invention features a fixing mechanism at the top of the propulsion unit. Pushing the pull rod causes the moving rod to slide against the outer wall of the sliding rod. The moving rod then moves the locking block, pushing the push handle, which in turn causes the disc to expel air from the collection cylinder. Releasing the pull rod allows the spring force to push the moving rod, which in turn causes the locking block to interlock with the push handle, thus fixing the push handle. This prevents water from pushing the disc into the collection cylinder before it comes into contact with the bottom sediment, ensuring the integrity of the bottom sediment collection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-5 As shown: Example

[0021] A sediment collection device for lake wetland surveys includes: A collection tube 1, with a disc 5 slidably installed inside the collection tube 1; Propulsion unit 2 is fixedly installed at one end of the collection tube 1; The moving mechanism is slidably connected to the collection tube 1 and the propulsion unit 2, and is fixedly connected to the top of the disk 5. The moving mechanism is used to drive the disk 5 to move. It should be noted that the disc 5 is set inside the collection tube 1, the moving mechanism is fixedly connected to the disc 5, and the propulsion unit 2 is fixedly installed at one end of the collection tube 1. The working principle of the propulsion unit 2 is the same as that of the electric underwater sediment sampling drill of model Vibecore-D. Before collecting bottom sediment from the lake, the moving mechanism drives the disc 5 to move, and the disc 5 discharges the air in the collection tube 1. The collection tube 1 is then placed into the lake, and the collection tube 1 sinks due to its own weight. The propulsion unit 2 is then activated, and the vibration of the propulsion unit 2 causes the collection tube 1 to sink into the bottom sediment, and the bottom sediment is collected through the collection tube 1. Specifically, mobile institutions include: Push rod 4, one end of push rod 4 is fixedly connected to disk 5, and the other end of push rod 4 is slidably connected to collection tube 1 and propulsion unit 2; Push handle 3, one end of push handle 3 is fixedly connected to the end of push rod 4 away from disk 5, and the end of push handle 3 away from push rod 4 is inserted and connected to locking part.

[0022] It should be noted that one end of the push rod 4 is fixedly connected to the disc 5, and the other end of the push rod 4 passes through the collection tube 1 and the propulsion unit 2 and is fixedly connected to the push handle 3. Before collecting bottom sediment from the lake, the push handle 3 is pushed, which drives the push rod 4 to move, which in turn drives the disc 5 to move. The disc 5 then expels the air from the collection tube 1, causing the push handle 3 to move to the surface of the propulsion unit 2. The push handle 3 is then fixed by a fixing mechanism to prevent water from impacting the disc 5 during the collection process, which could cause the disc 5 to loosen and allow water to enter the collection tube 1. The collection tube 1 is then placed in the lake, and its own weight causes it to sink. The propulsion unit 2 is then activated, and the vibration of the propulsion unit 2 causes the collection tube 1 to sink into the bottom sediment, where the bottom sediment is collected. A sealing ring 6 is fixedly installed on the outer wall of the disc 5, and the sealing ring 6 is slidably connected to the inner wall of the collection tube 1. It should be noted that the sealing ring 6 is fixedly installed on the outer wall of the disc 5 and is slidably connected to the inner wall of the collection tube 1. The sealing ring 6 seals the collection tube 1 to prevent air or water from entering the collection tube 1 and improves the sealing performance of the collection tube 1. In Embodiment 2, this utility model provides a fixing mechanism, which is applied to a bottom sediment collection device for lake wetland surveys in Embodiment 1. The fixing mechanism is located on the top of the propulsion unit 2. The fixing mechanism includes a moving part and a locking part. The locking part is interlocked with the moving mechanism and is used to fix the moving mechanism. The moving part is located on the top of the propulsion unit 2 and is used to push the locking part to move.

[0023] Specifically, the locking part includes a locking block 7, one end of which is slidably connected to the push handle 3, and the other end of which is fixedly connected to the moving part. Furthermore, the mobile unit includes: Mounting plates 8, multiple mounting plates 8 are symmetrically fixedly installed on the top of the propulsion unit 2; A sliding rod 9 is disposed between multiple mounting plates 8, and both ends of the sliding rod 9 are fixedly connected to one end of the multiple mounting plates 8 that is close to each other. The movable rod 10 is slidably sleeved on the outer wall of the sliding rod 9, and one end of the movable rod 10 is fixedly connected to the locking block 7. Pull rod 12, one end of which is fixedly connected to the top of the moving rod 10; It should be noted that multiple mounting plates 8 are fixedly installed on the surface of the propulsion unit 2. The ends of the multiple mounting plates 8 that are close to each other are fixedly connected to both ends of the sliding rod 9. The moving rod 10 is located between the multiple mounting plates 8 and is slidably sleeved on the outer wall of the sliding rod 9. The pull rod 12 is fixedly installed on the top of the moving rod 10. Before collecting bottom sediment from the lake, the pull rod 12 is pushed, which drives the moving rod 10 to slide on the outer wall of the sliding rod 9, so that the moving rod 10 moves away from the push rod 4. The moving rod 10 moves the locking block 7 away from the push rod 4, pushes the push handle 3, and drives the push rod 4 to move. The push rod 4 drives the disc 5 to move, and the disc 5 discharges the air in the collection tube 1, so that the push handle 3 moves to the surface of the propulsion unit 2. The pull rod 12 is released, and the moving rod 10 moves so that the locking block 7 and the push handle 3 are interlocked and connected, thereby fixing the push handle 3. This prevents the water flow from impacting the disc 5 during the collection process, causing the disc 5 to loosen and allowing water to enter the collection tube 1, thus ensuring the integrity of the bottom sediment collection. Specifically, a spring 11 is sleeved on the outer wall of the sliding rod 9. One end of the spring 11 is fixedly connected to one of the mounting plates 8, and the other end of the spring 11 is fixedly connected to the end of the moving rod 10 away from the locking block 7. It should be noted that the spring 11 is sleeved on the outer wall of the sliding rod 9. One end of the spring 11 is fixedly connected to one of the mounting plates 8, and the other end of the spring 11 is fixedly connected to the end of the moving frame away from the locking block 7. Before collecting bottom sediment from the lake, push the pull rod 12. The pull rod 12 drives the moving rod 10 to slide on the outer wall of the sliding rod 9, so that the moving rod 10 moves away from the push rod 4. The moving rod 10 moves the locking block 7 away from the push rod 4, pushes the push handle 3, and drives the push rod 4 to move. The push rod 4 drives the disc 5 to move, and the disc 5 discharges the air in the collection tube 1, so that the push handle 3 moves to the surface of the propulsion unit 2. Release the pull rod 12, and the spring 11 pushes the moving rod 10 to move. The moving rod 10 moves the locking block 7 and the push handle 3 to interlock and connect, thereby fixing the push handle 3 and preventing the water flow from impacting the disc 5 during the collection process, which would cause the disc 5 to loosen and allow water to enter the collection tube 1, thus ensuring the integrity of the bottom sediment collection. A fixed frame 13 is threadedly fitted at the end of the collection tube 1 away from the propulsion unit 2. Multiple limiting blocks 14 are fixedly installed inside the fixed frame 13, and the multiple limiting blocks 14 are arranged in a circle. It should be noted that one end of the fixing frame 13 is threadedly connected to the collection cylinder 1, and multiple limiting blocks 14 are arranged in a circle and fixedly installed inside the fixing frame 13. When the collection cylinder 1 is placed in the lake, the collection cylinder 1 sinks due to its own weight, which causes the fixing frame 13 to come into contact with the bottom sediment. The propulsion unit 2 is then activated, and the vibration of the propulsion unit 2 causes the collection cylinder 1 to sink into the bottom sediment, which in turn causes the bottom sediment to move into the collection cylinder 1 through the fixing frame 13. After the collection is completed, the collection cylinder 1 is pulled out of the lake. The limiting blocks 14 restrict the bottom sediment in the collection cylinder 1 to prevent the bottom sediment from sliding out of the collection cylinder 1 when it moves.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
