Compared with the existing technology, when the emptying type tide filter of the utility model carries out tidal observation measurement, when the filter
When surging outside wave duct, air and ambient atmosphere in cavity generate pressure difference, so that air flows in filtering hole, utilize filter
The small feature in wave hole aperture further makes the liquid level in cavity slow down, the fluctuation of water table period it is shorter surge interference by
Resistance, and it is smaller to period longer tidal level influence of change, achieve the purpose that filtering.The filtering hole of the utility model is exposed to sky
It in gas, is not susceptible to block, is easy to maintain, the filtering water inlet pipe for solving the pin-hole filter-ing device of the prior art tiny is easily blocked
The problem of plug.The emptying type tide filter water inlet cross-sectional area of the utility model and the ratio of the filtering tube cross-sectional area
Example, the ratio compared with prior art water inlet cross-sectional area and the filtering tube cross-sectional area is big, is not susceptible to block, and solves existing
There is the filtering water inlet pipe of the same category of device of technology comparatively fine, is placed in water easily blocked problem.The emptying of the utility model
Formula tide filter has the characteristics that structure is simple, is not susceptible to blocking, convenient for maintenance, good wave filtering effect.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.

It is connected to by a channel 13 with the cavity 10.The cross section of the embodiment of the present invention filtering tube 1 is arch.
The working principle of the emptying type tide filter of the utility model:
Tidal observation equipment a is placed in the cavity 10, the water inlet 12 of the filtering tube 1 is placed in water, by the filter
Wave hole 11 is exposed in air.
When external liquid level increases, the air pressure in the cavity 10 be equal to atmospheric pressure and external liquid level pressure difference and, it is described
Air in cavity 10 is forced to be discharged from the filtering hole 11, and since there is choked flow in the filtering hole 11, air can only
Slowly discharge, over time, the discharge rate of air gradually increases, inner and outer air pressure regional balance, in the cavity 10
Liquid level also approaches concordantly.
When external liquid level is lower than the liquid level in the cavity 10, due to the choked flow effect in the filtering hole 11, it is also desirable to
Inside and outside liquid level could balance after a period of time, and equilibration time depends on the size of filtering 11 diameter of hole, and diameter is smaller, resistance
Stream effect is bigger, and equilibration time is longer.
When the variation of outer liquid bit period, the SEA LEVEL VARIATION period, shorter surging was obstructed, and the SEA LEVEL VARIATION period is longer
Tide can pass through, to have the function that filtering, improve measurement effect.
Compared with the existing technology, when the emptying type tide filter of the utility model carries out tidal observation measurement, when the filter
When surging outside wave duct, air and ambient atmosphere in cavity generate pressure difference, so that air flows in filtering hole, utilize filter
The small feature in wave hole aperture further makes the liquid level in cavity slow down, the fluctuation of water table period it is shorter surge interference by
Resistance, and it is smaller to period longer tidal level influence of change, achieve the purpose that filtering.The filtering hole of the utility model is exposed to sky
It in gas, is not susceptible to block, is easy to maintain, the filtering water inlet pipe for solving the pin-hole filter-ing device of the prior art tiny is easily blocked
The problem of plug.The emptying type tide filter water inlet cross-sectional area of the utility model and the ratio of the filtering tube cross-sectional area
Example, the ratio compared with prior art water inlet cross-sectional area and the filtering tube cross-sectional area is big, is not susceptible to block, and solves existing
There is the filtering water inlet pipe of the same category of device of technology comparatively fine, is placed in water easily blocked problem.The emptying of the utility model
Formula tide filter has the characteristics that structure is simple, is not susceptible to blocking, convenient for maintenance, good wave filtering effect.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.
