Abstract
A mist curtain formed by high pressure liquid spraying can be used as extra-large display for projection TV sets, extra-large projection bill boards and the like. High pressure liquid pressurized by a high-lift pump reaches the injector through a high pressure pipe and is sprayed, forming a mist column multi instances of which forms a mist curtain.
Description
Technical field
The utility model relates to a kind of super large display screen of projection TV.
Background technology
At present the most products that use U.S. Stewart company and German Mu Wei company of jumbotron Projection Display are subjected to the restriction maximum of prior art can only accomplish 27 * 12m, also have splicing seams, pel spacing 6-30mm, more little expensive more, fragile, maintenance cost is also very high.
Summary of the invention
In order to overcome jumbotron field of projection display cost height, the problem of also using external product of poor quality, the utility model provides a kind of liquid high pressure of utilizing to spray the vaporific curtain wall that forms.Physical dimension can be big arbitrarily, and pel spacing can be arbitrarily small, and is not fragile, need not safeguard substantially, adjusts length, the shape of high-voltage tube, and the pressure of the quantity of shower nozzle, density and high-pressure pump just can be applied to other field.
The technical scheme that its technical matters that solves the utility model adopts is: pressurize to liquid with high-pressure pump, highly pressurised liquid arrives shower nozzle by high-voltage tube, from the ejection of shower nozzle high speed, form a fog-like liquid post again, a lot of such liquid columns are arranged in parallel and have just formed a vaporific curtain wall.
The beneficial effects of the utility model are: cost is low, and size is big, and purposes is wide.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the diagrammatic cross-section that liquid high pressure is sprayed first embodiment of curtain wall.
Fig. 2 is the diagrammatic cross-section that liquid high pressure is sprayed second embodiment of curtain wall.
Fig. 3 is the diagrammatic cross-section that liquid high pressure is sprayed the 3rd embodiment of curtain wall.
1. high-pressure pumps among the figure, 2. high-voltage tube, 3. shower nozzle, 4. curtain wall, 5. accumulator tank.
Embodiment
In the embodiment shown in fig. 1, high-pressure pump (1), high-voltage tube (2), shower nozzle (3), be installed in curtain wall (4) above, liquid is to following injection, sprays once more after having an accumulator tank (5) that liquids recovery is filtered below.This example is applicable to that indoor or outdoors rear-projection TV image, projection billboard use.
In embodiment illustrated in fig. 2, high-pressure pump (1), high-voltage tube (2), shower nozzle (3), be installed in a side of curtain wall (4), liquid is ejected into accumulator tank (5) to opposite side.This example is applicable to that indoor or outdoors is large-scale just, the rear-projection TV image, and large-scale projection billboard uses.
Usable range embodiment illustrated in fig. 3 is wider.High-pressure pump (1), high-voltage tube (2), shower nozzle (3), be installed in curtain wall (4) below, liquid sprays upward, does not establish accumulator tank (5), not withdrawal liquid.
Be used for outdoor ultra-large type projection television screen, when ultra-large type projection billboard uses.Preferably be installed in above the high-lager building, and the security protection facility is installed.Prevent the immense pressure of shower nozzle, personnel are damaged.
Be installed in around the ancient building, in a single day adjacent buildings has the condition of a fire to threaten, and sprays water curtain and isolates at once.
Be installed in around the airport, add the color of flying bird sensitivity in the liquid, spray colored curtain wall when having flying bird sudden and warn and isolate and drive.
Be installed on the boundary of wildlife reserve, add the color of wild animal sensitivity in the liquid, spray colored curtain wall when animal is arranged near boundary and isolate, when the protected location scope was big, high-pressure pump (1), high-voltage tube (2), shower nozzle (3) can divide into groups to install.
Be installed in around the military key area, interrupted injection is effectively taken precautions against.
On the defensive position, can effectively prevent resist the enemy tank, aircraft and infantry when being installed in war.For preventing that enemy's artillery fire from destroying, carry out the many groups of independence and repeat to install.
The environment for use temperature is when zero centigrade is above, and liquid makes water just passable, if the environment for use temperature below zero centigrade, can add freeze-point depressant in water, perhaps selects the lower liquid of freezing point.When liquid does not reclaim.Can increase air humidity, environment purification.
Because the high-pressure injection energy is very big, will consider safety factor during design, also will take care during use.Pressure boost is used for military key area strick precaution etc. will observe relevant regulations through relevant department's approval.Also to consider the requirement of terms of mechanics in the design of high-voltage tube and accumulator tank, when installing, firm and durable.
Liquid high pressure sprays that curtain wall shows as television image and projection billboard when using, and unique shortcoming is that influenced by ambient light bigger, and available light could guarantee sharpness seldom the time when just throwing, so will just adopt as required when designing, the rear-projection mode.
Claims (4)
1. a liquid high pressure is sprayed curtain wall, connect to form by high-pressure pump, high-voltage tube, shower nozzle, it is characterized in that: pressurize to liquid with high-pressure pump, highly pressurised liquid arrives shower nozzle by high-voltage tube, spray from the shower nozzle high speed again, form a fog-like liquid post, a lot of such liquid columns are arranged in parallel and have just formed a vaporific curtain wall.
2. liquid high pressure according to claim 1 is sprayed curtain wall, it is characterized in that: curtain wall is in 27 * 12m the time, and an accumulator tank is established on the shower nozzle opposite, sprays once more after liquids recovery is filtered.
