Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to a water and petroleum sampler. Background Technology
[0002] Existing petroleum samplers are stainless steel frame-type samplers. A glass bottle is placed in the sampler, and after it sinks to a specified depth, the stainless steel cap is opened to pour in the water sample. However, this device cannot accurately control the amount of water entering the sample, which does not meet the sampling requirements and affects the accuracy of the test data. In addition, when water is poured into the sampling bottle, sediments in the water will also enter the bottle, thus affecting the representativeness of the test data.
[0003] Therefore, there is an urgent need for a water quality petroleum sampler to solve the above problems. Utility Model Content
[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a water and petroleum sampler. By incorporating a connecting rod, an upper magnetic block, a lower magnetic block, and a telescopic spring, the two stainless steel filter screens with different apertures effectively block solid sediments in the water during sample collection, resulting in a more representative water sample. The device is compact; during water sample collection, a sampling rope is extended to the bottle opening. After collection, the device can be submerged in the sampling bottle, ensuring the integrity of the collected sample and addressing the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water and petroleum sampler, comprising an upper silicone collar, a large-aperture stainless steel filter screen bonded inside the upper silicone collar, a connecting rod welded to the bottom of the large-aperture stainless steel filter screen, an upper magnetic block fixedly mounted on the connecting rod, a lower magnetic block at the bottom of the upper magnetic block, a small-aperture stainless steel filter screen fixedly mounted on the outside of the lower magnetic block, a lower silicone collar bonded to the outside of the small-aperture stainless steel filter screen, a telescopic spring at the bottom of the small-aperture stainless steel filter screen, and a polytetrafluoroethylene plug fixedly mounted at the bottom of the telescopic spring.
[0006] In a preferred embodiment, the upper magnetic block is adapted to the lower magnetic block.
[0007] The technical effects and advantages of this utility model are as follows:
[0008] This invention, through its structure including a connecting rod, an upper magnetic block, a lower magnetic block, and a telescopic spring, allows the two stainless steel filter screens with different apertures to effectively block solid sediments in the water during sample collection, thus making the collected water sample more representative. The device is compact in design; during water sample collection, a sampling rope is extended to the bottle opening. After collection, the device can be submerged in the sampling bottle, ensuring the integrity of the collected sample. Attached Figure Description

[0011] 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.
[0012] As attached Figure 1 As shown, this utility model provides a water and petroleum sampler, including an upper silicone collar 2. A large-aperture stainless steel filter screen 1 is bonded to the inside of the upper silicone collar 2. A connecting rod 4 is welded to the bottom of the large-aperture stainless steel filter screen 1. An upper magnetic block 5 is fixedly installed on the connecting rod 4. A lower magnetic block 6 is provided at the bottom of the upper magnetic block 5. A small-aperture stainless steel filter screen 3 is fixedly installed on the outside of the lower magnetic block 6. A lower silicone collar 9 is bonded to the outside of the small-aperture stainless steel filter screen 3. A telescopic spring 8 is provided at the bottom of the small-aperture stainless steel filter screen 3. A polytetrafluoroethylene plug 7 is fixedly installed at the bottom of the telescopic spring 8.
[0013] The upper magnetic block 5 and the lower magnetic block 6 are adapted to each other.
[0014] The specific implementation method is as follows: When using this utility model, this device is used in conjunction with an existing sampler. The stainless steel cap of the existing sampler is connected to the connecting rod 4. During sample collection, the glass bottle of the existing sampler is fixed by a stainless steel frame and slowly lowered into the water. When the sampling rope reaches 30cm below the water surface, the stainless steel cap is pulled open, and at the same time, the connecting rod 4 is pulled to separate the upper magnetic block 5 and the lower magnetic block 6. At this time, the telescopic spring 8 is extended, and the water sample slowly enters the glass bottle through the large-diameter stainless steel filter screen 1 and the small-diameter stainless steel filter screen 3. As the water enters, the telescopic spring 8 slowly shortens. When the water sample is collected to the mouth of the brown glass bottle, the telescopic spring 8 returns to its original position, and the upper magnetic block 5 and the lower magnetic block 6 are tightly connected. The large-pore stainless steel filter 1 and the small-pore stainless steel filter 3 are also fitted together. At this time, the polytetrafluoroethylene stopper 7 also reaches the mouth of the glass bottle, forming a sealing device, preventing the water sample from entering the sampling bottle. After collection, acid is added to the sampling bottle as a preservative, and the connection between the stainless steel cap and the connecting rod 4 is disconnected, leaving the water sample in the glass sampling bottle. At this time, the sample collection is completed. This invention allows the two stainless steel filters with different pore sizes to effectively block solid sediments in the water during sample collection, making the collected water sample more representative. The device is compact in design. During water sample collection, the sampling rope is stretched to the mouth of the bottle. After the water sample is collected, the device can be submerged in the sampling bottle to ensure the integrity of the collected sample.
[0015] Working principle of this utility model:
[0016] Refer to the instruction manual appendix Figure 1 When using this utility model, the structure includes a connecting rod 4, an upper magnetic block 5, a lower magnetic block 6, and a telescopic spring 8.
