Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, the underwater fixed-point sampling barrel of the present invention includes a barrel body 1, a loam cake 2, and a lower bottom 3, and a waterproof steering gear 4 and a crossbeam 5 are fixed on the loam cake, and a disc cam 6 is housed on the waterproof steering gear shaft. The crossbeam is fixed on the two rails 7 of the bung, each of which has a spring 8 to withstand the crossbeam, a sliding groove is provided in the middle of the crossbeam, and the cam is embedded in the sliding groove, and the center of the upper cover and the lower bottom is provided with a cone. Shaped plug valve 9, the cone head is inserted into the valve downward to control the opening and closing of the valve, and the upper cover and the lower bottom are provided with three rails 10 for controlling the valve in an isosceles triangle distribution. It is fixedly connected with the valve on the upper cover.

[0017] During preparation, it is necessary t...

Abstract

The invention discloses an underwater spot sampling barrel which includes a barrel body, an upper cover and a lower bottom. A waterproof steering engine and a crossbeam are fixed on the upper cover. A steering shaft of the waterproof steering engine is provided with a disc cam. The crossbeam is fixed on two rails of the upper cover. Each rail is provided with a spring to press against the crossbeam. A sliding groove is formed in the middle of the crossbeam. The disc cam is embedded in the sliding groove. A valve is arranged on the center of each of the upper cover and the lower bottom. The two valves are connected to each other through a linking rod. The crossbeam is fixedly connected to the valve on the upper cover. By means of the technical scheme, the underwater spot sampling barrel can be used for underwater spot sampling at certain depth and achieves accurate sampling, thereby providing accurate data for sequential analytic tests.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an underwater fixed-point sampling barrel. Background technique [0002] At present, the sewage sampling method in the environmental monitoring method is generally about 40cm below the water surface of the river, and the sampling bucket is not closed to collect water, and the surface water samples are taken. For a long time, many environmental monitoring agencies have believed that surface water data at several locations can reflect the water quality of a river, but in practice it has been found many times that the water quality is different in different water areas and at different depths. How to explore the concentration law of water quality changes at different depths in a certain river? The hidden pollution sources that are secretly discharged underwater are the most difficult to find. Can this kind of regular exploration help us search for the pol...
