Description
Technical field
The present invention relates to solar water heating system and reveal autoalarm, belong to solar water heating system technical field.
Background technology
Solar water heating system is widely used in the units such as school, factory, apartment, hotel, office block, leisure club.Along with the reinforcement of people's energy-conserving and environment-protective consciousness, solar water heating system is used by everybody gradually.Solar water heating system is mainly to be combined by solar energy heat collecting module, heat storage water tank, intelligence control system, auxiliary heating system (electrical heating, heat pump etc.), pipeline and the circulatory system, can need to set out coolant-temperature gage according to user, realize the supply of 24 hours continuous hot waters.
The module that solar energy heat collecting module is comprised of many solar vacuum heat-collecting pipes, due to being widely used of vacuum heat collection pipe, run into unavoidably breaking or damaging of vacuum tube, cause the waste of a large amount of water resources, for user's use and safety, all caused great infringement simultaneously.Present stage, main method was, on water tank enters the pipeline of vacuum heat collection pipe, a pressure-detecting device is installed, and by the variation of detected pressures, realized the leak detection to vacuum heat collection pipe.But there is serious drawback in this leak detection mode: because pressure-detecting device cannot accurately be identified slight leaking, and water level decline 1m, pressure just can reduce 0.1Bar, and this just causes the situation of leaking not detect in time, cannot meet needs used in everyday.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of solar water heating system to reveal autoalarm, its structural design is novel, and reliable, intelligent degree is high, the situation of leaking can be detected in time and report to the police.
According to technical scheme provided by the invention: solar water heating system is revealed autoalarm, comprise solar energy heat collecting module, heat storage water tank and heat collector circulating pump, the water inlet of solar energy heat collecting module is connected by inlet channel with the delivery port of heat storage water tank, the delivery port of solar energy heat collecting module is connected by water return pipeline with the water inlet of heat storage water tank, and heat collector circulating pump is arranged on inlet channel or water return pipeline; It is characterized in that: also comprise first flow meter, the second flowmeter and intelligent alarm controller, described first flow meter, the second flow score are not arranged on inlet channel, water return pipeline, first flow meter, the second flow score are not connected with intelligent alarm controller by first signal line, secondary signal line, and intelligent alarm controller can detect and compare the data on flows on first flow meter, the second flowmeter; Described intelligent alarm controller is connected with heat collector circulating pump by the 3rd holding wire, and intelligent alarm controller can be controlled starting or stoping of heat collector circulating pump, and can send alarm signal.
compared with prior art, advantage is in the present invention:the present invention detects whether there is the situation of leaking by the difference in flow of solar energy heat collecting module water inlet and water outlet, intelligent alarm controller can carry out intelligent data computational analysis, accuracy and the promptness of leak detection have greatly been promoted, can show very accurately, delicately that whether solar water heating system leaks, and there will not be the phenomenons such as delay, wrong report.Even if very little leakage also can detect, and sends alarm signal in time, the maintenance of notice maintenance side, avoids the unmanned hot-water heating system paralysis of finding long-time leakage and causing and the waste of water resource.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the embodiment of the present invention.
Description of reference numerals: 1-solar energy heat collecting module, 2-heat storage water tank, 3-heat collector circulating pump, 4-first flow meter, 5-the second flowmeter, 6-intelligent alarm controller, 7-first signal line, 8-secondary signal line, 9-the 3rd holding wire.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the solar water heating system in embodiment is revealed autoalarm and mainly solar energy heat collecting module 1, heat storage water tank 2, heat collector circulating pump 3, first flow meter 4, the second flowmeter 5 and intelligent alarm controller 6 etc., consisted of.
As shown in Figure 1, the water inlet of solar energy heat collecting module 1 is connected by inlet channel with the delivery port of heat storage water tank 2, and the delivery port of solar energy heat collecting module 1 is connected by water return pipeline with the water inlet of heat storage water tank 2, and heat collector circulating pump 3 is arranged on inlet channel; Described first flow meter 4, the second flowmeter 5 are arranged on respectively on inlet channel, water return pipeline, first flow meter 4, the second flowmeter 5 are connected with intelligent alarm controller 6 by first signal line 7, secondary signal line 8 respectively, and intelligent alarm controller 6 can detect and compare the data on flows on first flow meter 4, the second flowmeter 5; Described intelligent alarm controller 6 is connected with heat collector circulating pump 3 by the 3rd holding wire 9, and intelligent alarm controller 6 can be controlled starting or stoping of heat collector circulating pump 3, and can send alarm signal.
Operation principle of the present invention and the course of work are as follows:
During use, after heat collector circulating pump 3 starts, first flow meter 4 and the second flowmeter 5 are passed to intelligent alarm controller 6 by data on flows signal respectively, under normal circumstances, the flow number of first flow meter 4 and the second flowmeter 5 should be in full accord, illustrates that solar water heating system is without leakage phenomenon.When first flow meter 4 data and the second flowmeter 5 differ more than 5%, illustrate that solar water heating system leaks, now intelligent alarm controller 6 sends alarm signal, sends control signal to heat collector circulating pump 3 simultaneously, make heat collector circulating pump 3 out of service, avoid a large amount of leakages.
Intelligent alarm controller 6 in the present invention can adopt commercially available conventional Programmable Logic Controller PLC, as long as it possesses and receives and compare flow signal, the function of sending control signal and alarm signal and showing flow situation, writes the calculating control program of writing according to above-mentioned operation principle in Programmable Logic Controller.
The present invention, by the intelligent data computational analysis of intelligent alarm controller 6, can draw the correct judgement whether solar water heating system leaks very accurately, delicately, there is no fear of occurring the phenomenons such as delay, wrong report.Even if very little leakage also can be diagnosed out, send in time warning, the maintenance of notice maintenance side, has avoided the unmanned discovery hot-water heating system paralysis that leakage causes for a long time and the waste of water resource.
