Description
Technical field
The utility model belongs to solar energy optical-thermal conversion facility technical field, is specifically related to the water-level and water-temperature sensor structure that a kind of engineering header of solar heating engineering is used.
Background technology
The notion of the solar heating engineering that the applicant mentions in the above is meant by some solar thermal collector arrays to be formed, concrete version can obtain understanding by centering state invention patent application publication number CN10165008A and publication No. CN101776327A, the water storage tank of each solar thermal collector under this version is referred to as the engineering header, and why being called the engineering header, this is because connected by pipeline each other between the adjacent water storage tank.
In order effectively water level in the engineering header and water temperature to be controlled in real time, on the engineering header, be equipped with water-level and water-temperature sensor usually, water-level and water-temperature sensor is connected by the controller of circuit with the engineering header.When for example when the water temperature in the water-level and water-temperature sensor perception engineering header reaches the temperature that is able to perception, reaching the temperature of setting, just give controller by water-level and water-temperature sensor with signal feedback, sending instruction by controller opens the water intaking valve on the inlet pipeline, external water source enters the engineering header, meanwhile, hot water in the engineering header is replaced to be gone out, draw by the road use for example the unit of printing and dyeing as the thermal source (hot water is introduced dye vat) of dyeing or be stored in the hot water water storage device (container) stand-by.And when the water level in the engineering header reduces or when claiming lack of water, then equally by the water-level and water-temperature sensor perception, with example when reaching the water level of setting, also by the water-level and water-temperature sensor perception, give controller with signal feedback simultaneously,, stop to the diversion of engineering header to close water intaking valve.
Structure about water-level and water-temperature sensor, in patent documentation, be seen in to some extent, the water-level and water-temperature sensor for solar water heater that typical case as practical novel license notification number CN2589897Y recommend, it is the conductor that a surface is wrapped up by fluoroplastic layer to be installed on many places on the tube wall have in the stainless steel tube in hole of the conductive resistance that is intended to reduce water, and thermistor is set in stainless steel tube, conductor and thermistor are connected with controller by circuit (patent claims lead), and whole operation principle is by the Instructions Page 2 final stage explanation of this patent.Should, this patent scheme overcome the deficiency in the prior art (the 1st page of the 6th to 15 line description of specification), the technique effect that the phase of having embodied gets.
But, the water-level and water-temperature sensor of said structure form still has shortcoming, being embodied in the water-level and water-temperature sensor body is connected cumbersome with lead between the controller, under normal conditions, reach tens meters, tens of several meters and even longer by the lead of drawing on the water-level and water-temperature sensor, and why be equipped with so tediously long lead, be because because the installation site of solar thermal collector is uncertain from the distance that is provided with between the controller.
Moreover, for solar heating engineering, the gross area of heat collector up to thousands of in addition surplus in the of ten thousand square metre more than, but still select for use common water-level and water-temperature sensor to be installed in to the regulation and control of so large-scale heat collector apart from the nearest pipeline of engineering header.Such behave certainly will cause following several drawback.The one, common water-level and water-temperature sensor and engineering header do not match, and both can't connect; The 2nd, in water-level and water-temperature parameter and the engineering header there be than mistake the water temperature parameter; The 3rd, the solar thermal collector matrix is positioned at the top of industrial premises, and is very far away apart from control room, ground distance, have to during installation original water-level and water-temperature sensor lead-in wire is cut off reclosing, and this reclosing is often impaired and out of control because of insulating.Therefore, the water-level and water-temperature sensor that research and development match with the engineering header has been imperative act.
In view of above-mentioned prior art, the applicant thinks and is necessary that the structure to water-level and water-temperature sensor is improved that technical scheme described below produces under this background.
