Abstract
The utility model discloses a water level monitor which is suitable for monitoring the water level which is unapproachable, particularly monitoring the water level of a water tower and a solar energy water heater in feeding water and using. The water level monitor is composed of a water level probe, a display circuit, an alarming device and connection cables. The user only needs to observe the light emitting situation of an LED of the display circuit to know the position of the water level when using the water level monitor. The water level monitor has the characteristics of simple structure, safe use and convenient monitoring.
Description
The utility model relates to a kind of Level monitor, and is particularly not accessible, intuitively the monitoring device of water level.Be applicable to the water level monitoring of water tower and solar water heater etc., or be applied to other non-water level monitoring intuitively places.
The water-line target that now is used for water tower is a floating-type, the device heaviness that water tower is inside and outside, and have must be in the inconvenience of outdoor observation.Place the solar water heater on building (room) top, lack Level monitor easily, only establish an overflow pipe and inform that water is full, or the way that installs the full alarm of water additional is not enough in tank top.How much water is what constantly make us being concerned about to also have in the water tank because in water utilizing process? do you promptly constantly wonder that water level wherein?
The purpose of this utility model provides a kind of water level monitor easily, realizes the water level and the variation thereof of solar water heater water tank (or water tower etc.) are monitored timely with simple structure.
The utility model is achieved in that with several light emitting diodes and is connected to suitable power supply by lead respectively, promptly constitute the loop of several luminous demonstrations, the wiring of each light emitting diode positive polarity is prolonged, be fixed in position on the rectangle insulcrete, each line at a certain distance, parallel longitudinal along plate is arranged, separated from each fixed position again, remove a bit of, make the lead of these disconnections constitute one group of water level switch that the conducting of water ability is arranged, then the insulcrete lead-in wire that this piece has been controlled water level switch up vertically put into water tank (or water tower), can monitor its water level.
In order to narrate conveniently, the part that handle assembly is put into water tank (or water tower etc.) is called probe; Several luminous loops of compositions such as several light emitting diodes and power supply are called display circuit; Water level switch on the insulcrete arranged from bottom to top be called first water level switch, second water level switch ..., the horizontal level of their correspondences is called first water level, second water level ...
When water does not flood water level switch, not conducting, light emitting diode is not luminous entirely; When water has flooded certain water level switch, because the electric conductivity of water makes the water level switch conducting, by lumination of light emitting diode in the display circuit of its control; When water no longer floods certain water level switch, because of losing the electric action of water, this water level switch not conducting again, no longer luminous by the corresponding light emitting diode of its control.Utilize the whether luminous of light emitting diode, demonstrate water level and whether arrive,, express the height of water level according to the luminous show state of difference.So,, just know the place of water level as long as observe the luminous situation of each light emitting diode.Such as, during work, the light emitting diode of display circuit is not luminous, knows that promptly one of water level switch does not have connection yet, and the water surface is below first water level; If any two lumination of light emitting diode, know that promptly second water level switch connected by water, the water surface is on second water level; All luminous when the light emitting diode of display circuit, make that to know that the water surface has been raised to the peak level of demonstration above, or the like.Device is provided with alarm device, can be with aural warning when showing peak level.
This apparatus structure is simple, is easy to make, and is safe in utilization, and monitoring is convenient, no matter general normal person has or not culture, shows luminous situation at a glance, just knows the place of water level.
Below with reference to accompanying drawing the utility model is described in further detail.
Fig. 1 is the electrical schematic diagram of the utility model device when being used to monitor five water levels.
With reference to Fig. 1, this device is by popping one's head in (1) polycore cable (2), display circuit (3) and alarm device (4) composition.
Fig. 2 has drawn a kind of version of probe (1).It is a printed circuit board that the single face copperclad plate is processed into.Multiple copper sheet (10) is the bridging line of five water level switches among the figure, and multiple copper sheet (11), (12), (13), (14), (15) are respectively the another side wiring of five water level switches.
With reference to Fig. 1, Fig. 2, display circuit is made up of power supply DC, K switch and five LEDs.(1) utmost point of power supply DC and an end of K switch join, the negative pole of the other end of K switch and five LED joins, (+) utmost point of the positive wire of five LED (31), (32), (33), (34), (35) and DC by polycore cable (2) and probe (1) (11), (12), (13), (14), (15) and (10) are corresponding joins.Alarm device (4) is an electronic door bell finished product of not being with the music IC work of shell and power supply, the dc voltage mid point of its positive wire and display circuit (3) joins, (1) utmost point of negative wire and DC joins, and triggers lead-in wire d and is connected on (35) of display circuit (3).
The vertical height of probe (1) will adapt with the maximum height of monitored water level, and to general solar water heater water tank, the water level switch number is got 3-10, promptly satisfies request for utilization, and when being used for water tower, the water level switch number can be greater than 10.The crosspiece of the multiple copper sheet (11) in the printed board, (12), (13), (14), (15) is the sign of five water levels, parallel to each other, spacing equates, the crosspiece of multiple copper sheet (11) is apart from the lower edge of printed board, (15) crosspiece is apart from the upper edge of printed board, and half of the column pitch of all fetching water is advisable.The distance of multiple each crosspiece of copper sheet and multiple copper sheet (10) is several millimeters to ten several millimeters, and the live width of each multiple copper sheet is got the 2-10 millimeter.Multiple copper sheet will plate the rustless metal, and to printed board integral body clean, nontoxic processing.Probe (1) also can be set on the insulation framework of the system of giving with the rustless metal sheet and make, and technical requirement and printed board are roughly the same.DC in the display circuit (3) is that four joint 1.5V batteries are formed the effective common LED of light-emitting diodes.
Alarm device (4) and display circuit (3) be with being contained in during plastics close, and is placed on the user and observes locally easily, and the user can the limit water, the variation of limit monitoring water level.
