Description

Technical Field

[0001] This utility model relates to the field of water ecological restoration technology, and in particular to a silt sampler for water ecological restoration. Background Technology

[0002] Aquatic ecological restoration refers to restoring damaged aquatic ecosystems to a healthy and stable state through the self-regulation and self-organization capabilities of the ecosystem, supplemented by artificial measures, and developing them towards a virtuous cycle. During restoration, it is necessary to sample the silt, which is generally done using a sampler. However, because silt is fluid and the lower end of the sampler is open, silt can easily flow out of the sampler when it is pulled out of the silt. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies that easily lead to sludge flowing out of the sampler, and to propose a sludge sampler for water ecological restoration.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a sludge sampler for water ecological restoration, including a sampling cylinder, a connecting sleeve fixedly connected to the sampling cylinder, a handle fixedly connected to the connecting sleeve, a rotating shaft rotatably connected to the sampling cylinder via a bearing, a sealing cap fixedly connected to the rotating shaft, and a connecting ear fixedly connected to the rotating shaft, the connecting ear being fixed by a fixing mechanism.

[0006] Preferably, a conical head is fixedly connected to the lower end of the sealing cap.

[0007] Preferably, the fixing mechanism includes a fixing ring, which is fixedly connected to the sampling tube. The fixing ring has two fixing holes. A bolt is threaded through the connecting lug, and an insertion post is fixedly connected to the bolt, with the insertion post extending into the fixing holes.

[0008] Preferably, the diameter of the insertion post is larger than the inner diameter of the fixing hole.

[0009] Preferably, the connecting sleeve is connected to the sampling cylinder, a threaded rod is threaded through the handle, a piston is fixedly connected to the threaded rod, and the piston abuts against the inner wall of the sampling cylinder.

[0010] Preferably, a rotating block is fixedly connected to the threaded rod.

[0011] The present invention proposes a sludge sampler for water ecological restoration, which has the following advantages: when the sampler is pulled out of the sludge, the rotating shaft makes the sealing cover abut against the lower end of the sampling tube, thereby preventing the sludge from flowing out, while ensuring the stratification of the sludge after sampling and preventing the upper layer of sludge from being mixed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-3 A sludge sampler for aquatic ecological restoration includes a sampling cylinder 1, a connecting sleeve 5 fixedly connected to the sampling cylinder 1, a handle 7 fixedly connected to the connecting sleeve 5, a rotating shaft 4 rotatably connected to the sampling cylinder 1 via a bearing, a sealing cap 2 fixedly connected to the rotating shaft 4, and a connecting ear 12 fixedly connected to the rotating shaft 4. The connecting ear 12 is fixed by a fixing mechanism. When the sampler is pulled out of the sludge, the rotating shaft 4 is rotated so that the sealing cap 2 abuts against the lower end of the sampling cylinder 1, thereby preventing the sludge from flowing out and ensuring that the sludge is stratified after sampling, without mixing the upper layer of sludge.

[0018] A conical head 3 is fixedly connected to the lower end of the sealing cap 2 so that it can be inserted into the silt.

[0019] Example 2: Refer to Figure 1-3In another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a fixing ring 8, which is fixedly connected to the sampling cylinder 1. The fixing ring 8 has two fixing holes 9. A bolt 10 is threaded through the connecting lug 12, and an insertion post 11 is fixedly connected to the bolt 10, extending into the fixing hole 9. By connecting the insertion post 11 to the fixing hole 9, the rotating shaft 4 is fixed, thereby determining the position of the sealing cover 2. This allows the insertion post 11 to be inserted into different fixing holes 9, representing different states of the sealing cover 2.

[0020] The diameter of the insertion post 11 is larger than the inner diameter of the fixing hole 9, which prevents the bolt 10 from coming out of the threaded hole.

[0021] Example 3: Reference Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 2, the connecting sleeve 5 is connected to the sampling cylinder 1, and a threaded rod 6 is threaded through the handle 7. A piston 13 is fixedly connected to the threaded rod 6, and the piston 13 abuts against the inner wall of the sampling cylinder 1. A rotating block is fixedly connected to the threaded rod 6. The threaded rod 6 is made of stainless steel. By rotating the threaded rod 6, the adjusting bolt 6 is positioned inside the handle 7, which will drive the piston 13 to move, so as to push out the sludge in the sampling cylinder 1 and prevent the sludge from remaining in the sampling cylinder 1.

[0022] During sampling, the device is as follows Figure 1 The sampler is inserted into the sludge as shown. Then, the bolt 10 is turned to disengage the insertion post 11 from the fixing hole 9. The connecting ear 12 is rotated 180° so that the sealing cover 2 abuts against the lower end of the sampling tube 1 to seal the lower end of the sampling tube 1. The bolt 10 is tightened to connect the insertion post 11 to the fixing hole 9. The sampler is then pulled out of the sludge. The sealing cover 2 is then opened, and the threaded rod 6 is rotated to move the piston 13 and push out the sludge in the sampling tube 1.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
