Description

Technical Field

[0001] The utility model relates to the technical field of water sampler devices, in particular to an upright emptying water sampler. Background Art

[0002] The emptying type water sampler is widely used for surface water sampling. It is suitable for the collection of water quality samples other than bacterial indicators and oils, and can also be used for the collection of aquatic biological samples. The traditional emptying type water sampler is mainly composed of three parts: the barrel, the weight ring and the built-in thermometer. Its working principle is as follows: the top and bottom of the barrel have two semicircular covers that open upward in the same direction. When the sampler sinks into the water, the two semicircular covers at both ends open upward accordingly. The water does not stay in the sampler. When it reaches the predetermined depth, it is lifted up and the semicircular covers at both ends are covered, and the sample of the required depth is obtained. The weight ring is designed mainly for the sinking of the water sampler. Without the weighted barrel, it is impossible to collect deep water samples, and only surface water samples can be collected.

[0003] According to the requirements of the "Technical Specifications for Surface Water Environmental Quality Monitoring" (HJ91.2-2022) and the "Technical Guidance for Water Quality Sampling" (HJ494-2009), when the water depth of rivers, lakes and reservoirs is 5-10m, or when the water depth is greater than 10m, sampling is required at 0.5m above the water bottom. Since the traditional emptying water sampler does not have the function of measuring the water depth, in actual applications, it is necessary to measure the water depth on site with a rope and a ruler with a weight, and then control the sampling depth by adjusting the length of the water sampler rope. As mentioned above, there are two problems in the use of traditional water samplers: first, it is inconvenient to measure the water depth first and then adjust and control the sampling depth, and the sampling work efficiency is low; second, due to the rapid flow and floating of the water body, the sampling rope is difficult to keep vertical, and it is easy to form a winding, resulting in the actual sampling depth being inconsistent with the sampling specification requirements, and even stirring the sediment at the bottom of the water, causing pollution to the water sampler and water samples. Therefore, this application proposes an upright emptying water sampler. Utility Model Content

[0004] In order to overcome the problems in the background technology, the utility model provides an upright emptying water sampler to solve the problems existing in the use of traditional water samplers, such as the need to first measure the water depth and then adjust and control the sampling depth, which is inconvenient to operate, the low sampling efficiency, and the difficulty in keeping the sampling rope vertical due to the influence of rapid currents and floating of the water body, resulting in inaccurate sampling depth and stirring of sediments at the bottom of the water.

[0005] An upright emptying water sampler comprises a water sampling tube, a movable upper cover, a movable lower cover, a counterweight ring, a bracket and a handle; the handle is installed on the top of the side wall of the water sampling tube, a water outlet is provided at the bottom of the side wall of the water sampling tube, a movable upper cover with a rotating shaft is flipped upwardly and installed on the opening at the top of the water sampling tube, a movable lower cover with a rotating shaft is flipped upwardly and installed on the water inlet at the bottom of the water sampling tube, the counterweight ring is installed on the outer wall of the lower part of the water sampling tube, and the bracket comprises a connecting sleeve and a telescopic rod, the connecting sleeve is threadedly connected to the counterweight ring, and the upper end of the telescopic rod is evenly fixed to the connecting sleeve.

[0006] Furthermore, the telescopic length of the telescopic rod is 50-100 cm

[0007] Furthermore, a transparent hollow measuring tube is installed on the sleeve of the telescopic rod, and a measuring scale is marked on the measuring tube.

[0008] Furthermore, a thermometer is installed in the water sampling tube.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The present application is provided with a bracket, which is connected to the counterweight ring through a connecting sleeve, so that the water sampling tube is supported at the required sampling height from the water bottom. When sampling, the water sampler can be directly placed on the water bottom without measuring the water depth in advance and then adjusting the rope length, which solves the problem of inconvenient operation and low sampling efficiency in the use of traditional water samplers, which requires measuring the water depth first and then adjusting the sampling depth. The telescopic rod of the bracket of the present application is adjustable in length. If there is sediment on the bottom of the water, the influence of the sediment can be deducted by appropriately increasing the length of the telescopic rod to complete the water sampling at the required depth. The measuring tube provided on the telescopic rod can measure the depth of the bottom of the telescopic rod inserted into the sediment, which is convenient for judging the depth of the sediment, and solves the problem that the use of traditional water samplers is affected by the rapids and floating of the water body, and the sampling rope is difficult to keep vertical, resulting in inaccurate sampling depth and stirring of sediment at the bottom of the water.
