Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, and specifically relates to a petroleum sampler. Background Technology

[0002] There are many types of petroleum samplers on the market, with the mainstream ones including dual-rope samplers and float samplers. Although this type of sampler can meet the requirement of collecting samples at a certain depth below the water surface, it is prone to half-full or full conditions due to water level fluctuations, and the water sample enters the bottle from both sides, which does not meet the requirements for columnar water sample collection.

[0003] Accurate analysis of oil content in water is crucial for environmental protection and water quality management. However, existing patent literature on oil sample collection methods has many limitations. For example, the sampling process requires a high level of expertise to ensure the representativeness and consistency of the samples. Typically, dry sample bottles are used for sampling, and columnar water samples need to be collected from the water surface to 30 mm. Existing patent literature has pointed out that using unsuitable collection tools may damage the integrity of the samples due to poor sealing, resulting in missing or contaminated samples, which is detrimental to monitoring.

[0004] To address the aforementioned technical problems, a petroleum sampler needs to be designed to improve the accuracy and reliability of sample collection. It should possess the following characteristics: 1. The design is ingenious and easy to operate, reducing the requirements for the professional skills of the operators.

[0005] 2. The original state of the sample can be maintained during the sampling process to avoid contamination, damage or leakage of the sample. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model proposes a petroleum sampler that adopts a sliding part and a driven plate design, which makes the sampling process simpler, reduces the difficulty of operation, and allows for accurate sampling without requiring highly professional skills. Through the sliding cooperation between the driven plate and the L-shaped plate, as well as the sealing design between the circular plate and the inlet, the contamination, damage or leakage of the sample is effectively prevented, ensuring the representativeness and consistency of the sample.

[0007] The technical solution of this utility model is: a petroleum sampler, comprising: A cylindrical body for collecting columnar water, the bottom of the cylindrical body having an inlet; the top of the cylindrical body having an opening, the opening having a plug; A sliding part, which is connected to the bottom of the inner cavity of the cylinder, is located outside the inlet; The driven plate is slidably connected to the sliding part.

[0008] Preferably, the sliding part includes a plurality of L-shaped plates arranged in a circumferential array. The vertical plate of the L-shaped plate is connected to the bottom wall of the inner cavity of the cylinder, the horizontal plate of the L-shaped plate is parallel to the bottom wall of the inner cavity of the cylinder, the driven plate is located inside the vertical plate of the L-shaped plate and slides in cooperation with it, and the driven plate is located below the horizontal plate of the L-shaped plate.

[0009] Preferably, the driven plate includes: A circular plate, wherein the circular plate is slidably fitted to the inner side of the vertical plate of the L-shaped plate; The second circular plate is connected at its top to the bottom of the first circular plate. The size of the second circular plate is smaller than that of the first circular plate. The second circular plate is adapted to the inlet. The surface of the second circular plate is treated with frosted glass.

[0010] Preferably, the bottom of the cylinder is provided with an annular plate, the outer wall of the annular plate is provided with external threads, the external threads of the annular plate are threaded to a sealing cover, the sealing cover is connected to a valve, and the valve is detachably connected to a negative pressure device.

[0011] Preferably, the bottom of the cylinder is connected to a plurality of support legs arranged in a circular pattern, and the lower surface of the support legs is lower than the lower surface of the sealing cover.

[0012] Preferably, the outer wall of the cylinder is connected to two symmetrical fixing plates, and a handle is hinged between the two fixing plates.

[0013] Preferably, the outer wall of the cylinder is provided with scale lines, which are located away from the inlet.

[0014] This utility model has the following advantages and effects compared with the prior art: (1) The design of the sliding part and the driven plate makes the sampling process simpler and reduces the difficulty of operation. Accurate sampling can be carried out without high professional skills. Through the sliding cooperation between the driven plate and the L-shaped plate, and the sealing design between the circular plate and the inlet, the contamination, damage or leakage of the sample is effectively prevented, ensuring the representativeness and consistency of the sample.

[0015] (2) The combination of the annular plate and the closed cover, as well as the negative pressure device of the valve connection, enhances the sealing of the sampler, prevents sample leakage, and ensures the accuracy of the sampling amount.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0023] Example 1: like Figures 1-5 As shown, this utility model provides a petroleum sampler, including: a cylinder 1, which is used to collect columnar water, and an inlet 10 is provided at the bottom of the cylinder 1; an opening is provided at the top of the cylinder 1, and a plug 11 is provided at the opening. The sliding part is connected to the bottom of the inner cavity of the cylinder 1, and the sliding part is located outside the inlet 10; Driven plate 2 is slidably connected to the sliding part.

[0024] In some embodiments, an overflow valve (not shown in the figure) is provided on one side of the outer wall of the cylinder 1.

[0025] The sliding part includes several L-shaped plates 3 arranged in a circular array. The vertical plate of the L-shaped plate 3 is connected to the bottom wall of the inner cavity of the cylinder 1, and the horizontal plate of the L-shaped plate 3 is parallel to the bottom wall of the inner cavity of the cylinder 1. The driven plate 2 is located inside the vertical plate of the L-shaped plate 3 and slides in cooperation with it. The driven plate 2 is located below the horizontal plate of the L-shaped plate 3.

[0026] The driven plate 2 includes: Circular plate 20 slides with the inner side of the vertical plate of L-shaped plate 3. Round plate 21, the top of round plate 21 is connected to the bottom of round plate 1 20, the size of round plate 21 is smaller than the size of round plate 1 20, round plate 21 is adapted to the inlet 10, and the surface of round plate 21 is treated with frosted glass.

[0027] The bottom of the cylinder 1 is provided with an annular plate 4, and the outer wall of the annular plate 4 is provided with external threads (not shown in the figure). The external threads of the annular plate 4 are connected to a sealing cover 5, and the sealing cover 5 is connected to a valve 50. The valve 50 is detachably connected to a negative pressure device.

[0028] Several support legs 12 arranged in a circular pattern are connected to the bottom of the cylinder 1. The lower surface of the support legs 12 is lower than the lower surface of the closed cover 5.

[0029] The outer wall of the cylinder 1 is connected to two symmetrical fixed plates 13, and a handle 14 is hinged between the two fixed plates 13.

[0030] The outer wall of the cylinder 1 is provided with scale lines 6, which are located away from the inlet 10.

[0031] In some embodiments, the cylinder 1 is made of transparent brown glass.

[0032] In some embodiments, the bottom of the plug 11 is treated with frosted glass.

[0033] In some embodiments, a water immersion alarm (not shown in the figure) is provided inside the cylinder 1, and the water immersion alarm is located on one side of the scale line 6.

[0034] When in use, water flows through the water immersion alarm, which then sounds an alarm to remind the operator that the column water collection is complete. The monitoring by the water immersion alarm can prevent over-sampling and ensure the original state and integrity of the sample, reminding the operator that the column water collection is complete.

[0035] Plug 11 Working principle: When the alarm is triggered, it will sound to alert staff to the column water sample. Sampling preparation: First, place the cylinder 1 in the water body to be sampled, ensuring that the inlet 10 at the bottom of the cylinder 1 is submerged to a depth of 30 mm above the water surface. The water flow pushes the driven plate 2. When the water flow enters the inlet 10 at the bottom of the cylinder 1, it will push the driven plate 2 to slide. The driven plate 2 is slidably connected to the L-shaped plate 3. When the driven plate 2 moves away from the bottom wall of the inner cavity of the cylinder 1, the water flow enters the interior of the cylinder 1 from the inlet 10. For sealing and protection, the driven plate 2 includes a first circular plate 20 and a second circular plate 21, wherein the second circular plate 21 is adapted to the inlet 10 and is treated with frosted glass. After the columnar water collection is completed, the driven plate 2 approaches the bottom wall of the inner cavity of the cylinder 1, and the second circular plate 21 enters the inlet 10 to seal the columnar water and prevent leakage. To improve the sealing performance, the annular plate 4 is screwed onto the sealing cap 5, which further improves the sealing performance of this utility model. The valve 50 is connected to a negative pressure device, which draws out a portion of the air and then closes the valve, making the driven plate 2 more tightly sealed and further preventing sample leakage. For support and carrying, the support legs 12 connected to the bottom of the cylinder 1 provide stable support. The fixing plate 13 connected to the outer wall of the cylinder 1 and the hinged handle 14 facilitate carrying. The sampling volume indicator, with scale lines 6 set on the outer wall of the cylinder 1, helps operators observe the sampling volume to determine whether it meets the requirements.

[0036] In summary, the water quality sampler of this invention can efficiently and accurately collect columnar samples while ensuring the original state of the samples.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
