Technical field
The present invention relates to water conservancy field of monitoring devices, particularly to a kind of float water level detection means.
Background technology
Water level measuring and controlling device is important measuring and controlling equipment, and it provides important reference data for Safety of Flood Control.Water conservancy at present
Generally carry out the device of level measuring using float gauge or ultrasonic water level detection means in industry.Float gauge includes
Float, drawstring, pulley, balancing weight and sensing water level encoder, balancing weight and float are hung on the both sides of pulley respectively by drawstring,
When float with water level mobile when, balancing weight makees reverse motions in the presence of drawstring, and drawstring can be with during movement
Pulley rotation, sensing water level encoder is arranged with pulley coaxle, and it just can obtain current level value according to the rotation of pulley.But,
Because sensing water level encoder must be that drawstring drives pulley rotation to get up to perceive the change of water level when mobile, when drawstring exists
Pulley is led to not make corresponding rotation because occurring to skid with pulley in the process of movement, or because SEA LEVEL VARIATION is more slow
Slowly lead to drawstring mobile slow and movable pulley can not be carried to make corresponding rotation, then sensing water level encoder just can not induce water level
Change, thus lead to water level detecting result inaccurate.
The information being disclosed in this background section is merely intended to increase the understanding of the general background to the present invention, and should not
Recognize when being considered or imply in any form that this information structure has been the prior art well known to persons skilled in the art.
Content of the invention
It is an object of the invention to provide a kind of float water level detection means, thus overcome existing float water level detection dress
Put and movable pulley can not be carried when rope occurs to skid or movement is slow to make corresponding rotation and lead to testing result inaccurate
Shortcoming.
For achieving the above object, the invention provides a kind of float water level detection means, wherein, including：Guard shield, under it is in
The cylindrical shape of end opening, this guard shield is arranged in frame；Pulley, it is arranged at the upper end of described guard shield；Drawstring, it bypasses described
Pulley, so that the two ends of this drawstring are distributed in the both sides of described pulley；Float, it is fixedly connected with one end of described drawstring, should
Buoys float is on the water surface；The height of described guard shield is more than the stroke of this float；Balancing weight, it is solid with the other end of described drawstring
Fixed connection；And ultrasonic range finder, it is arranged in described guard shield, and this ultrasonic range finder is just being located at described balancing weight
Top, to detect the distance of this ultrasonic range finder and described balancing weight.
Preferably, in technique scheme, the quantity of described ultrasonic range finder is two, one of described ultrasonic wave
When rangefinder uses as normal detection, another described ultrasonic range finder is as standby.
Preferably, in technique scheme, described float is in spherical shape.
Preferably, in technique scheme, the upper end of described guard shield is provided with the cover lid opened or close.
Preferably, in technique scheme, the lower end of described guard shield is in bell mouth shape.
Preferably, in technique scheme, in described guard shield, it is provided with a dividing plate, the side wall of described dividing plate and described guard shield
Between form a chute, described balancing weight is sheathed in described chute in the way of can sliding up and down.
Compared with prior art, the present invention has the advantages that：
1st, by ultrasonic range finder, the present invention detects that the distance between itself and balancing weight obtain current level value to convert,
As long as water level changes, the position between float and balancing weight also will necessarily change, from regardless of whether whether drawstring skids,
Whether SEA LEVEL VARIATION is slow, and it all can detect current level, and its testing result is accurate and easy to use.
2nd, the chute that in the guard shield of the present invention, logical ground dividing plate facilitates balancing weight to slide up and down with side wall formation one, thus keep
The linearity of balancing weight movement, prevents balancing weight from swinging, to improve accuracy of detection.
