Embodiment 1
[0066] like Figure 5 to Figure 9 As shown, the vertical channel water collector of the rotation body includes: a cylindrical water storage bucket 1 with open ends at both ends. The water storage device 1 is 33 cm high and 9.8 cm in inner diameter, and is made of ABS injection molding. Device 1 runs through up and down. The water collector has a capacity of 2.5L, a height of 36cm, and a weight of 2.5kg.
[0067] The upper damping plate 2-1 and the lower damping plate 2-2 are respectively fixed on the upper and lower ends of the water storage device 1, the thickness of the upper damping plate 2-1 and the lower damping plate 2-2 is 8mm, and the upper damping plate 2-1 and one side of the lower damping plate 2-2 are connected to the shaft sleeve;
[0068] The upper damping plate 2-1 is provided with a hinged valve cover 8, and the valve cover 8 can cover the upper end of the water storage device 1;
[0069] The lower damping plate 2-2 is provided with a water discharge valve 6...

Abstract
The invention discloses an autorotation vertical-channel water sampler, and belongs to the technical field of water samplers. The autorotation vertical-channel water sampler comprises a vertically through water storage device, an upper damping plate, a lower damping plate, a swivel shaft, a shaft sleeve, a rubber water seal and a base; the upper damping plate and the lower damping plate are respectively fixed on upper and lower ends of the water storage device; one sides of the upper damping plate and the lower damping plate are connected to the shaft sleeve; a valve cover is arranged on the upper damping plate; the valve cover can be covered at the upper end of the water storage device; a water drain valve is arranged on the lower damping plate; one end of the water drain valve is communicated with the water storage device; the other end of the water drain valve is provided with a water faucet; the shaft sleeve sleeves the swivel shaft; the shaft sleeve can relatively slide along theaxial direction of the swivel shaft, and can rotate by taking the swivel shaft as the axis; a first ring is arranged on the top of the swivel shaft; the rubber water seal is positioned at the bottom of the lower damping plate and connected with the bottom of the water storage device; the base is connected with the bottom of the swivel shaft; the rubber water seal can be appressed to the surface ofthe base; and a weight balancing block is built in the base. The water sampler is unique in structure and convenient to operate; and thus, precise stratified sampling can be realized.
Description
technical field [0001] The invention belongs to the technical field of water collectors, in particular to a water collector with a vertical channel of a self-rotating body. Background technique [0002] At present, when collecting water within 100 meters of water depth in China, most of them use plexiglass water collectors, stainless steel water collectors, card cover type water collectors or lifting type water collectors to collect water. When the plexiglass water collector and the stainless steel water collector are lowered into the water, due to the bypass flow of the movable floor valve, there is always a large amount of upper layer water in the chamber of the water collector, which causes confusion in the water samples collected in layers and leads to inaccurate survey data. reality. [0003] The flow around the movable floor valve of the plexiglass water collector and the stainless steel water collector is analyzed below (the theory of the flow around the square colum...
