Description
Technical field
The invention belongs to hydrophore technical fields, and in particular to a kind of from swivel Vertical Channel hydrophore.
Background technique
The country uses organic glass hydrophore, stainless steel hydrophore, Ka Gai in 100 meter Nei Cai water of the depth of water mostly at present
Formula hydrophore or hoisting type hydrophore carry out adopting water.Organic glass hydrophore, stainless steel hydrophore in water in decentralization process because
Dump bottom plate valve streams, and leading to hydrophore cavity total is to have a large amount of upper water, causes the water sample of stratified sampling to obscure, causes
Survey data is untrue.
Organic glass hydrophore, stainless steel hydrophore dump bottom plate valve are streamed below and analyzed that (square column streams reason
It is streamed by bottom plate valve is suitable for).
Square shaped column rounded flowing pattern analytical calculation: square column streams Region Decomposition and uses a kind of algorithm based on graph theory, it
It is to be proposed by G.L.Miller et al. in 1994.Feature is the coordinate that node is utilized, and the optimization of Region Decomposition is asked
Topic is converted into solution system of linear equations.This algorithm is based primarily upon the concept of Radon point, by the projective transformation of point set and to center
The solution of point, finally realizes subdivision.Calculated result is as follows:
It is verified in the following several ways by velocity field fluidised form.
1. the laminar flow stage, in the case where Re=1~50, flowing belongs to laminar flow, and be it is permanent, as Re=1,5, due to stream
Bulk viscosity is very big, and flow velocity is very slow, generates when flowing through square column without burble point.With the increase of Re, occur a pair of stablize behind cylinder
Whirlpool, as shown in Fig. 1 (Re=1,30).
Reflux area length L is directed to when verifyingrIt is verified and the empirical equation L of Breuerr/D=-0.065+
0.0554Re (5 < Re < 60) fits like a glove, as shown in Figure 2.
2. Karman vortex street further increases with Reynolds number, the subsequent vortex of cylinder gradually tends to be asymmetric, in cylinder
Staggered Karman vortex street is formed below.Fluidised form evolution schematic diagram when Fig. 3 is Re=100.Two above and below being clear that
A vortex generates, develops, falls off and downstream moves the periodicity of the phenomenon that forming cycle staggering arrangement and wake zone flowing
It swings.
And pressed cover hydrophore or hoisting type hydrophore are more heavy, and cumbersome, it is necessary to be equipped with dedicated winch and
Steel wire cable.Flow velocity is only used for less than 80 cm/s, the depth of water less than the sampling in 10 meters of water bodys.Water bottle both ends
Two Ka Gai are connected with each other by the rubber strip of root knot reality, will firmly pulling out two Ka Gai is stuck in bottle simultaneously when opening
Mouthful.The steel wire for pulling Connection Release machine, meticulously hangs up properly relieving mechanism.When hydrophore reaches desired depth, from steel wire
What is fallen on cable makes hammer hit relieving mechanism, closes hydrophore.When water volume flow rate is greater than 80 cm/s, the depth of water is greater than 10
Rice, the tilt angle for lifting the steel wire cable of hydrophore increase, and reduce the slow potential energy of the falling speed of hammer, are difficult excitation release
Mechanism.If relieving mechanism is not energized, the Ka Gai at water bottle both ends cannot be closed.When hydrophore lifting rises the water surface out, water
The Ka Gai at bottle both ends is not turned off, and removing makes to hammer into shape, is needed again to transfer to hydrophore and is required the depth of water, and is loaded onto and made to hammer into shape, again
Excite relieving mechanism.The labor intensity for increasing on-site land survey personnel is easy to miss the timing node of Multipoint synchronous observation.
Therefore, the research of hydrophore is just particularly important.
