Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater samplers, specifically relating to a sampler for industrial wastewater testing. Background Technology

[0002] Sampling of industrial wastewater requires specialized equipment to ensure sample representativeness, accuracy, and safety. Manual samplers, including buckets or sampling bottles (materials: glass / polyethylene / stainless steel), are suitable for instantaneous sampling of shallow wastewater.

[0003] However, existing manual samplers often lack the ability to collect samples at specific depths. They can only collect surface sewage after being lowered into the ground and cannot collect samples of deeper wastewater, which has certain limitations and makes them inconvenient to use. Therefore, there is an urgent need for a sampler for industrial wastewater testing to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a sampler for industrial wastewater testing, so as to solve the problem mentioned in the background art that the existing manual samplers often do not have the function of collecting samples at a specific depth, and often can only collect surface sewage after being lowered, and cannot collect deep wastewater.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampler for industrial wastewater testing, comprising a sampling bucket, a fixing ring, a cover plate, a pull rope one, a telescopic structure, and a pull rope two. A counterweight is fixedly connected to the bottom of the sampling bucket, and a handle is rotatably connected to the top of the sampling bucket. The telescopic structure includes a fixing plate one, a fixing rod, and a fixing plate two. The fixing plate one is fixedly connected to both the front and rear sides of the sampling bucket. A fixing rod is fixedly connected to the top of the fixing plate one, and a sliding rod is slidably connected to the fixing rod. The top of the sliding rod is fixedly connected to the fixing plate two. The fixing plate two is fixedly connected to both the front and rear sides of the fixing ring. A threaded ring is fixedly connected to the bottom of the cover plate, and the threaded ring is threadedly connected to the fixing ring. A rotating plate is fixedly connected to the top of the cover plate, and a pull rope one is fixedly connected to the top of the rotating plate. A buckle is fixedly connected to the bottom of the pull rope two, and the buckle is movably connected to the handle.

[0006] Preferably, a limiting plate is fixedly connected to the bottom of the sliding rod, and the limiting plate is slidably connected to a fixing plate.

[0007] Preferably, a tension spring is fitted inside the fixing rod, with one end of the tension spring abutting against the inner wall of the bottom end of the fixing rod and the other end of the tension spring abutting against the bottom of the limiting plate.

[0008] Preferably, a sealing ring is fixedly connected to the bottom of the fixing ring, and the sealing ring is located at the joint between the fixing ring and the sampling bucket.

[0009] Preferably, a second sealing ring is fixedly connected to the bottom of the cover plate, and the second sealing ring is located at the joint between the cover plate and the fixing ring.

[0010] Preferably, the surface of the second pull rope is provided with a scale.

[0011] Preferably, the top of the fixing rod is provided with a multi-lip silicone ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This industrial wastewater sampling instrument is equipped with a pull rope, a scale, and a buckle. The handle is inserted into the buckle, which facilitates the quick installation and disassembly of the sampling bucket, making it convenient to replace the sampling bucket later. The sampling bucket is lifted by the pull rope and lowered into the sewage tank or sewage well. The height of the lowering can be read by the scale, which is convenient for sampling wastewater at a specific depth.

[0014] 2. This industrial wastewater sampling instrument is equipped with a sampling bucket, a fixed ring, and a telescopic structure. After lowering to a suitable height, pulling the first pull rope causes the cover plate to move upward, which in turn moves the fixed ring upward. This causes the tension spring to stretch under pressure, opening the fixed ring and allowing wastewater to enter the sampling bucket. Releasing the first pull rope causes the tension spring to push the fixed ring downward. Combined with the weight of the fixed ring and the cover plate, the fixed ring covers the sampling bucket. A sealing ring seals the joint between the fixed ring and the sampling bucket, ensuring a tight seal. Pulling the second pull rope allows the sampling bucket to be removed. The combined use of the sampling bucket, fixed ring, and telescopic structure allows for sampling wastewater at specific depths, offering high flexibility, strong practicality, and a simple and easy-to-use design.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides an embodiment of a sampler for industrial wastewater testing, comprising a sampling bucket 1, a fixing ring 2, a cover plate 3, a pull rope 4, a telescopic structure 5, and a pull rope 6. A counterweight 11 is fixedly connected to the bottom of the sampling bucket 1, and a handle 12 is rotatably connected to the top of the sampling bucket 1. The telescopic structure 5 includes a fixing plate 51, a fixing rod 52, and a fixing plate 56. The fixing plate 51 is fixedly connected to both the front and rear sides of the sampling bucket 1. The fixing rod 52 is fixedly connected to the top of the fixing plate 51, and the fixing rod 52 is slidably connected to a sliding rod 53. The top of the sliding rod 53... Fixed plate 2 56 is fixedly connected to the front and rear sides of fixed ring 2. Threaded ring 32 is fixedly connected to the bottom of cover plate 3. Threaded ring 32 is threadedly connected to fixed ring 2. Rotating plate 33 is fixedly connected to the top of cover plate 3. Pull rope 1 4 is fixedly connected to the top of rotating plate 33. Buckle 62 is fixedly connected to the bottom of pull rope 2 6. Buckle 62 is movably connected to handle 12. Through the combined use of sampling bucket 1, fixed ring 2, and telescopic structure 5, wastewater at a specific depth can be sampled. It has high flexibility, strong practicality, and a simple structure that is easy to use.

[0024] Furthermore, a limiting plate 54 is fixedly connected to the bottom of the sliding rod 53, and the limiting plate 54 is slidably connected to the fixed plate 51. The limiting plate 54 plays a limiting role, preventing the sliding rod 53 from disengaging from the fixed plate 51, and making the sliding of the fixed plate 51 more stable, thus improving the stability during movement. The diameter of the limiting plate 54 is slightly smaller than the diameter of the inner groove of the fixed plate 51, so that when the limiting plate 54 slides, the air above the limiting plate 54 can circulate to the bottom of the limiting plate 54.

[0025] Furthermore, a tension spring 55 is fitted inside the fixing rod 52. One end of the tension spring 55 abuts against the inner wall of the bottom end of the fixing rod 52, and the other end of the tension spring 55 abuts against the bottom of the limiting plate 54. Pulling the pull rope 4 causes the pull rope 4 to move the cover plate 3 upward, which in turn causes the cover plate 3 to move the fixing ring 2 upward. This causes the tension spring 55 to be compressed and stretched, thereby opening the fixing ring 2. Releasing the pull rope 4 causes the elastic force of the tension spring 55 to push the fixing ring 2 downward. Combined with the weight of the fixing ring 2 and the cover plate 3, the fixing ring 2 covers the sampling bucket 1.

[0026] Furthermore, a sealing ring 21 is fixedly connected to the bottom of the fixing ring 2. The sealing ring 21 is located at the joint between the fixing ring 2 and the sampling bucket 1. A sealing ring 31 is fixedly connected to the bottom of the cover plate 3. The sealing ring 31 is located at the joint between the cover plate 3 and the fixing ring 2. The sealing ring 21 seals the joint between the fixing ring 2 and the sampling bucket 1, ensuring airtightness. The sealing ring 31 seals the joint between the cover plate 3 and the fixing ring 2, ensuring airtightness.

[0027] Furthermore, the surface of the second rope 6 is provided with a scale 61, through which the lowering height can be read, making it convenient to sample wastewater at a specific depth.

[0028] Furthermore, a multi-lip silicone ring is provided at the top of the fixing rod 52 to ensure that the sliding rod 53 remains sealed when it extends or retracts.

[0029] Working principle: In use, place the cover plate 3 on the fixing ring 2, rotate the rotating plate 33 to make the cover plate 3 rotate, so that the sealing ring 31 is screwed into the fixing ring 2. The sealing ring 31 seals the joint between the cover plate 3 and the fixing ring 2, ensuring airtightness. Insert the handle 12 into the buckle 62, which facilitates quick installation and removal of the sampling bucket 1, making it convenient for future replacement. Use the pull rope 6 to lift the sampling bucket 1 and lower it into the sewage tank or sewage well. The counterweight 11 increases the weight of the sampling bucket 1, causing it to sink into the sewage. The lowering height can be read from the scale 61. After lowering to the appropriate height, pull... Pulling rope 4 causes the cover plate 3 to move upward, which in turn moves the fixing ring 2 upward. This causes the tension spring 55 to stretch under pressure, opening the fixing ring 2 and allowing sewage to enter the sampling bucket 1. Releasing rope 4 causes the tension spring 55 to push the fixing ring 2 downward. Combined with the weight of the fixing ring 2 and the cover plate 3, the fixing ring 2 covers the sampling bucket 1. The sealing ring 21 seals the joint between the fixing ring 2 and the sampling bucket 1, ensuring a tight seal. Pulling rope 6 allows the sampling bucket 1 to be removed. The combined use of the sampling bucket 1, the fixing ring 2, and the telescopic structure 5 allows for sampling of wastewater at specific depths. This method offers high flexibility, strong practicality, and a simple and easy-to-use structure.
