Abstract
Disclosed is a self-cleaning scale water level and water temperature sensor. A detection rod of the sensor is made of a stainless steel round tube (3) and a non-poisonous high-temperature resistant insulation round tube (5) in a sectioned manner, and three groups of equally divided tension springs (2) are mounted on a top cap (1) and pull wiping balls (6) capable of wiping off scale. When a sealed electromagnet (15) begins to work, a magnetic conduction pull-up ring (11) is sucked down, and all the wiping balls (6) on the whole detection rod can be pulled by pulling connecting stainless steel wires (4). When the magnetic conduction pull-up ring (11) is sucked to contact with the sealed electromagnet (15), the sealed electromagnet (15) automatically loses power and excitation. The wiping balls (6) are pulled to an original position and reset under the action of the tension springs on the top cap (1) at the top of the detection rod, the scale outside the sectioned stainless steel round tube (3) on the detection rod is wiped off as the wiping balls are pulled back and forth, the conducting rate of water is kept, the scale is normally displayed, and steady operation is realized.
Description
Technical field
The present invention relates to the sensor device of the water-level and water-temperature on a kind of solar water heater, particularly a kind of be not afraid of incrusted from clear water dirt water-level and water-temperature sensor.
Background technology
On solar water heater, water-level and water-temperature sensor great majority used are all to adopt resistance pattern to use water as the water level that conductor realizes in water tank to show, but owing to being easy to fouling after water heating, cause the increase of resistance value to make to show malfunctioning.Also there is the magnetic floating ring dry reed tube formula that adopts, although the not water funk fouling of this device is used in the place that water quality is poor, be also afraid of long-term fouling, the gap of pipe and floating ring can be tied cannot float time and made too display cannot show water level.
Summary of the invention
In order to solve above weak point, the invention provides a kind of can often remove incrustation scale from clear water dirt cooling-water temperature sensor, thoroughly solve water scale problems.
The present invention to the technical scheme providing from clear water dirt water-level and water-temperature sensor is;
The test rod of its water-level and water-temperature and original resistance-type are roughly the same, are also segmentation conductings, and every section of centre has the resistance of different resistances to connect, and head and the tail wire is drawn to water tank outside, and temperature detection unit device is also placed in the inside of test rod, and wire is drawn water tank outside.The segmentation of test rod is to have the non-toxic plastic of stainless conductor pipe and insulation high-temperature-resistant to make, and is all hollow body, and wire can be guided from top bottom into always, the top of test rod be sealing do not allow water inlet, bottom is to lead directly to water tank outside.The extension spring of on the block on top, three groups of deciles being housed, extension spring hauls the wiping ball that can wipe incrustation scale, wiping ball is the outside at each stainless pipe of test rod, with stainless steel wire, they are coupled together, until the magnetic conduction of bottommost is inhaled on moving-coil, the bottom that magnetic conduction is inhaled moving-coil is closed type electromagnet, and the work of electromagnet is discontinuous, and namely when energising, it is the working forms that has certain frequency.
Accompanying drawing explanation
By drawings and Examples, the present invention is described further from clear water dirt water-level and water-temperature sensor;
Fig. 1 is that the present invention is from the schematic diagram of clear water dirt water-level and water-temperature sensor.
Fig. 2 is that the electromagnetism having amplified is inhaled the schematic diagram of moving part.
(1) in figure is top cap, (2) extension spring, (3) stainless pipe, (4) pull connection stainless steel wire, (5) nontoxic high-temperature insulation pipe, (6) wipe ball, (7) resistor, (8) temperature sensor, the pad of (9) resistor and stainless pipe, (10) porose outer tube, (11) magnetic conduction is inhaled moving-coil, (12) closed type electromagnet, (13) waterproof washer, (14) water level, temperature sensing extension line, (15) closed type electromagnet extension line.
The enforcement of finding out it from accompanying drawing is also very simple, when closed type electromagnet (15) is started working, magnetic conduction is inhaled under moving-coil (11) suction, by pulling connection stainless steel wire (4) that the wiping ball (6) on whole piece test rod is pulled entirely, when magnetic conduction, inhale moving-coil (11) and be drawn onto while contacting with closed type electromagnet (15), closed type electromagnet (15) is also loss of excitation of dead electricity automatically.Due to extension spring (2) effect on the top cap (1) at test rod top, wipe ball and be pulled to origin-location, making to wipe ball (6) resets, pulling so back and forth wiped the outside fouling of segmentation stainless pipe (3) on test rod thoroughly, the on-state rate that keeps water, incrustation scale is shown normal, steady operation.
Claims (2)
1. the test rod that it has stainless pipe (3) to be connected with nontoxic high-temperature insulation pipe (5) and to form from clear water dirt water-level and water-temperature sensor, is characterized in that: in the outside of stainless pipe (3), also placing the wiping ball (6) that can wipe incrustation scale.
2. according to claim 1 from clear water dirt water-level and water-temperature sensor, it is characterized in that: it also has that closed type electromagnet (15) magnetic conduction inhales that moving-coil (11) pulls that the wiping ball (6) that connects on stainless steel wire (4) and extension spring (2) form certainly please incrustation scale device.
