Description
Technical Field
The utility model relates to the technical field of surface water monitoring, in particular to a siphon sampling device after a surface water sample is placed statically.
Background
In the monitoring and sampling process of surface water bodies such as rivers, lakes and the like, when indexes such as chemical oxygen demand, permanganate index, total nitrogen, total phosphorus and the like are collected, a water sample needs to be naturally settled for 30 min. The non-settling part on the upper layer of the water sample is used for removing the water sample in a siphon mode, and a water inlet of a siphon needs to be inserted to a position below 50mm of the surface layer of the water sample.
The traditional siphon sampling device is very simple and easy, and mostly adopts a silicone tube and an earbud matched combination for sampling. Because the device is relatively simple, the position of the silicone tube needs to be manually adjusted in real time along with the continuous reduction of the water level in the standing container; and in the sampling process, because the elasticity of silicone tube itself is better, need the people hand to press the pipe constantly, ensure that the water inlet is located 50mm position under the surface of water and normally intake. Thus, at least 2 people are needed to be matched simultaneously to collect water samples to the sampling bottle smoothly, so that the waste of on-site monitoring human resources is caused, the working efficiency is influenced, and misoperation is easy to occur. Moreover, only one siphon is used for suction filtration, and the siphon is inserted into the bottom of the bottle, so that the sediment at the bottom can be stirred, and the siphon can be bent and blocked at the bottle mouth of the water sample bottle, thereby easily causing the defect that the suction filtration process cannot be normally carried out.
Therefore, there is a need for a siphon sampling device that can satisfy the siphon sampling requirement in a relatively stable state and reduce the labor intensity of the monitoring personnel.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model provides a siphon sampling device for a surface water sample after standing, which uses a dynamic balance structure to ensure that a siphon pipeline can meet the siphon sampling requirement in a relatively stable state all the time, and can be conveniently operated by a single person, thereby reducing the labor intensity of monitoring personnel, and the specific technical scheme is as follows:
the utility model relates to a siphon sampling device for a surface water sample after standing, which comprises a standing container, a hose and a water collecting container.
And an adjusting device is arranged at the upper port of the standing container.
The adjusting device comprises a cover plate capable of completely covering the upper port of the standing container, a plurality of rotating wheels which are positioned on the same circle by taking the midpoint of the cover plate as the center and are arranged at equal intervals, through holes which are arranged on the cover plate and are close to the rotating wheels, and a floating device for adjusting the water drawing height.
One end of the hose extends into the water collecting container, and the other end of the hose bypasses the rotating wheel and penetrates through the through hole to be connected with the floating device.
Furthermore, the outer wall of the upper port of the standing container is provided with a circle of mortise, and the bottom surface of the cover plate is provided with a circle of tenon matched with the mortise. The tenon and the mortise are mutually matched, so that the cover plate of the standing container and the cover plate of the adjusting device can be locked, and the mutual sliding is avoided.
Further, a sliding rail for accommodating the hose is arranged on the rotating wheel.
Further, the floating device comprises a floating plate, a counterweight member arranged right below the floating plate and a fixing hole penetrating through the centers of the floating plate and the counterweight member. The floating device can float on the liquid level in a vertically downward posture of the counterweight under the combined action of the floating plate and the counterweight, so that the hose inserted into the through hole can be ensured to be capable of always drawing a water sample.
Further, the length of the weight member is 50 mm. The standard water inlet amount of the hose for drawing the water sample is 50mm, so that the water inlet amount of the hose can be kept unchanged at 50mm only by inserting the end of the hose into the through hole and aligning with the bottom end of the through hole, manual adjustment of personnel is not needed in the whole process, and the labor intensity of operators is greatly reduced.
Furthermore, the preparation material of the container that stews is polyethylene, and the inner wall is provided with the scale mark, makes things convenient for operating personnel to observe the residual water sample volume in the container that stews.
