Technical Field
[0001] This utility model relates to the field of sewage collection technology, and in particular to a municipal sewage sampling device. Background Technology
[0002] Municipal sewage refers to the general term for domestic sewage, industrial wastewater, and runoff sewage within urban areas. Because water quality can vary significantly at different depths, especially in water bodies with obvious stratification or uneven mixing, it is sometimes necessary to sample at different depths when collecting sewage. However, existing sewage sampling devices are generally composed of sampling tubes, which cannot sample sewage at different depths when placed in the sewage. Utility Model Content

[0007] Preferably, the connecting cover is provided with anti-slip texture.
[0008] Preferably, the reset mechanism includes a connecting ear, which is fixedly connected to the connecting post. A limiting hole is formed on the connecting ear, and the moving post is located in the limiting hole. A spring is sleeved on the moving post, with one end of the spring fixedly connected to the connecting ear and the other end fixedly connected to the sealing plug.
[0009] Preferably, the spring is a stainless steel spring.
[0010] Preferably, the pulling mechanism includes a hinge seat, which is fixedly connected to the connecting column, and a hinge part is rotatably connected to the hinge seat, the hinge part being connected to the connecting rope.
[0011] Preferably, a fixed pulley is fixedly connected to the connecting column, and the connecting rope passes through the fixed pulley.
[0012] The municipal sewage sampling device proposed in this utility model has the following advantages: according to the scale line, the storage cylinder is inserted into sewage at different depths, and the pulling mechanism pulls the sealing plug to move, so that water can enter from the water inlet and be sampled from sewage at different depths.

[0018] 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.
[0019] Example 1: Refer to Figure 1-4 A municipal sewage sampling device includes a storage cylinder 1 with an inlet hole 14. A sealing mechanism is provided at the lower end of the storage cylinder 1. A connecting column 3 is fixedly connected to the storage cylinder 1. A movable column 6 is connected to the connecting column 3 through a reset mechanism. A sealing plug 9 is fixedly connected to the movable column 6 and is located inside the inlet hole 14. A scale line 4 is provided on the connecting column 3. A connecting rope 5 is connected to the movable column 6. The connecting rope 5 is pulled by a pulling mechanism. According to the scale line 4, the storage cylinder 1 is inserted into sewage at different depths. The pulling mechanism pulls the sealing plug 9 to move, and water enters from the inlet hole 14 to sample sewage at different depths.
[0020] The reset mechanism includes a connecting ear 7, which is fixedly connected to the connecting post 3. A limit hole is provided on the connecting ear 7, and the moving post 6 is located in the limit hole. A spring 8 is sleeved on the moving post 6. The spring 8 is a stainless steel spring. One end of the spring 8 is fixedly connected to the connecting ear 7, and the other end is fixedly connected to the sealing plug 9. By using the restoring force of the spring 8, the sealing plug 9 is pressed against the water inlet hole 14 to play a sealing role and prevent water from entering. When it is inserted to the depth required for sampling, it drives the moving post 6 to move, thereby opening the sealing plug 9.
[0021] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the sealing mechanism includes a connecting cover 2, which is provided with a sealing ring to perform the sealing function. The connecting cover 2 is provided with anti-slip texture. The connecting cover 2 is threadedly connected to the storage cylinder 1. A discharge valve 13 is provided on the connecting cover 2. By opening the connecting cover 2, the storage cylinder 1 can be opened to clean the inside of the storage cylinder 1 and prevent residue from appearing in the storage cylinder 1, which would affect the next sampling result.
[0022] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 2, the pulling mechanism includes a hinge seat 12, which is fixedly connected to the connecting column 3. A hinge part 11 is rotatably connected to the hinge seat 12, and the hinge part 11 is connected to the connecting rope 5. By pressing the hinge part 11, the other end of the hinge part 11 is raised, pulling the connecting rope 5 to move. This causes the connecting rope 5 to pull the moving column 6 to move, which in turn moves the sealing plug 9, opening the water inlet 14 and allowing sewage to enter the storage cylinder 1. The spring 8 is compressed. When the hinge part 11 is released, the sealing plug 9 re-seals under the restoring force of the spring 8.
[0023] A fixed pulley 10 is fixedly connected to the connecting column 3, and the connecting rope 5 passes through the fixed pulley 10. The fixed pulley 10 guides the connecting rope 5.
[0024] 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.
