Description

Technical Field

[0001] This utility model relates to the field of bed sand sampling technology, specifically to a plow-type sampler for riverbed sand. Background Technology

[0002] The plow sampler, an important tool for riverbed sediment sampling, is mainly used to collect sediment (including coarse particles such as pebbles) from the bottom of riverbeds. The plow sampler has a relatively simple and stable structure and is widely used in riverbed sediment sampling technology.

[0003] The plow sampler, in conjunction with counterweight lead blocks and a bottom net, connects a winch and control console via steel wire to collect bed sediment samples. While the plow sampler facilitates the collection of bed sediment data at grassroots hydrological stations, existing plow samplers are inefficient, relying primarily on manual removal of pebbles for sieving and weighing. Therefore, to address these issues, it is necessary to propose a plow sampler for riverbed sediment that offers higher efficiency and facilitates pebble removal. Summary of the Invention

[0004] To address the aforementioned shortcomings of the existing technology, this utility model provides a plow-type sampler for riverbed sand.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: it includes a collection bucket, a circular discharge port is provided at the bottom of the collection bucket, a bottom mesh assembly is hinged to the circular discharge port, a rotating support plate is provided on the side of the circular discharge port away from the hinge end, two mesh frame side screws are provided on the side of the collection bucket to lock the bottom mesh assembly, and a baffle is fixed to the rear side of the collection bucket.

[0006] Furthermore, the bottom mesh assembly includes a circular mesh frame, a bottom mesh, and a circular pressure frame. The circular mesh frame has an L-shaped cross-section, and the bottom mesh is fixed to the bottom mesh by the circular pressure frame.

[0007] Furthermore, the bottom of the circular discharge port is provided with a stepped section that cooperates with the circular mesh frame.

[0008] Furthermore, the circular mesh frame is provided with a hinged end, and the circular discharge port is provided with a hinged opening that mates with the hinged end. The hinged opening and the hinged end are hinged together by a pivot.

[0009] Furthermore, two reinforcing frames are installed at the top of the collection bucket.

[0010] Furthermore, four hanging buckles are evenly distributed on the top of the collection bucket.

[0011] Furthermore, the rotating support plate is provided with rotating holes, and the rotating support plate is rotatably installed at the bottom of the collection bucket by means of support plate rivets.

[0012] Furthermore, two side extension rods are fixed to the side of the collection bucket. A transverse tail fin is rotatably mounted on the middle of the side extension rod via a hinge shaft, and a limit shaft is provided on the rear side of the side extension rod.

[0013] Furthermore, a vertical tail fin is fixed to the rear side of each side extension rod.

[0014] Furthermore, the bottom of the collection bucket is evenly distributed with four support feet.

[0015] The beneficial effects of this utility model are as follows: The bottom of the sampling bucket of this utility model is equipped with an openable bottom net assembly, which can realize the rapid dumping of riverbed sediment in the sampling bucket, greatly facilitating the removal of riverbed sediment. The rear side of the sampling bucket is equipped with a horizontal tail fin and a vertical tail fin, which can make the sampling bucket more stable in the water, thereby greatly improving the sampling efficiency.

[0016] This invention features a bottom mesh assembly hinged to the bottom of the collection bucket. The bottom mesh assembly includes a circular mesh frame, a bottom mesh, and a circular pressure frame. The bottom mesh is fixed to the circular mesh frame by the circular pressure frame, facilitating maintenance and replacement of the bottom mesh assembly. During sampling, the circular mesh frame completes the sampling process through the support of a rotating support plate and the locking action of screws on the side of the mesh frame. After sampling, when the support of the rotating support plate and the locking action of the screws on the side of the mesh frame are removed, the bed sand in the collection bucket can open the bottom mesh assembly by gravity, thereby enabling the rapid removal of pebbles from the collection bucket. Once the pebbles in the collection bucket are emptied, the next sampling operation can be easily carried out.

[0017] The sampling bucket of this invention is fixed with two vertical tail fins and one adaptively rotatable horizontal tail fin by two side extension rods. When the sampling bucket moves in the water, the horizontal tail fin enters the water and is as parallel as possible to the direction of water flow, making it less likely for the sampling bucket to flip vertically. The vertical tail fin makes it less likely for the sampling bucket to flip horizontally, thus ensuring the stability of the sampling bucket when moving in the water and ensuring the sampling effect.

Detailed Implementation

[0019] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0020] like Figure 1 and 2 As shown, the riverbed sand plow sampler includes a collection bucket 1, with a circular discharge port 101 at the bottom. A bottom mesh assembly is hinged to the circular discharge port 101. A rotating support plate 5 is located on the side of the circular discharge port 101 away from the hinge end. Two side screws 7 are provided on the side of the collection bucket 1 to lock the bottom mesh assembly. A baffle plate 103 is fixed to the rear of the collection bucket 1. The baffle plate 103 is preferably a stainless steel perforated plate, which has a good service life. At the same time, the holes facilitate the drainage of water from the collection bucket 1, making it easy for the collection bucket 1 to move in the water and drain water from the collection bucket 1. Several toothed claws can also be provided at the front end of the collection bucket 1. The toothed claws can better cooperate with the movement of the collection bucket 1 to sample mud, sand and gravel at the bottom of the riverbed.

[0021] like Figure 3 As shown, the bottom mesh assembly includes a circular mesh frame 2, a bottom mesh 3, and a circular pressure frame 4. The circular mesh frame 2 has an L-shaped cross-section, and the bottom mesh 3 is fixed to the bottom mesh 3 by the circular pressure frame 4. The bottom of the circular discharge port 101 has a stepped portion that mates with the circular mesh frame 2. The circular mesh frame 2 and the circular pressure frame 4, when mate with the stepped portion, securely press the bottom mesh 3 between the circular mesh frame 2 and the circular pressure frame 4. A hinge end 21 is provided on the circular mesh frame 2, and a hinge opening 102 is provided on the circular discharge port 101 that mates with the hinge end 21. The hinge opening 102 and the hinge end 21 are hinged together by a pivot. A threaded hole is provided on the collection hopper 1 for mounting the side screws 7 of the mesh frame, and a slot is provided on the circular mesh frame 2 for mates with the side screws 7. When the small end of the side screw 7 is screwed into the slot, the circular mesh frame 2 is fixed. The circular mesh frame 2, the circular pressure frame 4, and the bottom mesh 3 can also be designed in a rectangular shape. The rectangular bottom mesh assembly allows the bottom of the collection hopper 1 to have a larger discharge port, thereby allowing the collected bed sand to be discharged from the collection hopper more quickly.

[0022] The top of the collection bucket 1 is equipped with two reinforcing frames 8. The top of the collection bucket 1 can be reinforced by the reinforcing frames 8, which can improve the overall structural strength of the collection bucket 1, prevent the collection bucket 1 from deforming during full-load lifting, and improve the safety of operation.

[0023] The top of the collection bucket 1 is evenly equipped with four lifting hooks 9. These hooks, in conjunction with crisscrossing steel wire ropes, allow the collection bucket 1 to be lifted. The four hooks 9 ensure more even force distribution during lifting, preventing the collection bucket 1 from tipping over. A connecting swivel on the crisscrossing steel wire ropes at each hook 9 releases tension, preventing the sampler from spinning under stress and effectively avoiding collisions with the vessel hull, thus facilitating the collection of riverbed sediment.

[0024] The rotating support plate 5 is equipped with rotating holes. The rotating support plate 5 is rotatably mounted on the bottom of the collection bucket 1 via support plate rivets 6. Rotating the supporting end of the rotating support plate 5 to the bottom of the bottom net assembly provides some support for the bottom net assembly. The rotating support plate 5 can also be equipped with rope buckles connected to steel wire ropes. Pulling the steel wire ropes drives the rotating support plate 5 to rotate, making it easier to open the bottom net assembly and empty the collected bed sand.

[0025] Two side extension rods 10 are fixed to the side of the sampling bucket 1. A transverse tail fin 12 is rotatably mounted on the middle of the side extension rod 10 via a hinge shaft 13. A limit shaft 14 is provided on the rear side of the side extension rod 10. A vertical tail fin 11 is fixed to the rear side of each side extension rod 10. The vertical tail fin 11 and the transverse tail fin 12 are made as parallel as possible to the direction of water flow. The vertical tail fin 11 can effectively prevent the sampling bucket 1 from flipping laterally in the water, ensuring the lateral stability of the sampling bucket 1 when moving in the water. The transverse tail fin 12 can rotate around the hinge shaft 13, and under the limiting action of the limit shaft 14, it can adaptively swing in the water, thereby further ensuring the stability of the sampling bucket 1 when moving in the water and preventing the sampling bucket 1 from shaking in the water after sampling, which would cause the collected sand sample to spill out.

[0026] Four support feet 104 are evenly distributed and fixed at the bottom of the collection bucket 1. The four support feet 104 can support the bottom of the collection bucket 1, so that the bottom of the collection bucket 1 can be better dried when it is not in use, which can effectively slow down the oxidation and corrosion of the collection bucket 1 and extend the service life of the collection bucket 1.

[0027] Working process and its principle: S1: When in use, tie the steel wire ropes in a cross shape at the four hanging buckles 9, and then set the hook in the middle of the steel wire ropes. Use the lifting equipment and the hooks to lift the collection bucket 1. S2: The bottom mesh 3 is pressed and fixed onto the circular mesh frame 2 by the circular pressure frame 4; S3: Fold the circular mesh frame 2 to the bottom of the collection bucket 1, and rotate the support plate 5 to support the bottom of the circular mesh frame 2. At the same time, rotate the two side screws 7 of the mesh frame to further lock and fix the circular mesh frame 2. S4: Use lifting equipment and hooks to lift the collection bucket 1 to collect riverbed sand. After collecting the riverbed sand, lift the collection bucket 1 back to the initial position. S5: First, rotate the support plate 5 to the non-supported position, lift the collection bucket 1 and place it on the deck, then rotate the two side screws 7 of the mesh frame to open the circular mesh frame 2. Finally, lift the collection bucket 1 to a certain height, and use the gravity of the riverbed sand in the collection bucket 1 to make the circular mesh frame 2 rotate and open, thereby releasing the collected riverbed sand from the collection bucket 1. Compared with the existing method, it is more labor-saving to remove the riverbed sand.
