Abstract
The utility model discloses a water level measurement system for a solar water heater. The system comprises a floater which is arranged in a water storage device of the solar water heater, a rope is connected with the floater, the other end of the rope passes through a fixed pulley and then is connected with a pendulous object, the fixed pulley and the pendulous object are arranged outside the water storage device, and a measurement device for measuring rotation turns and rotation direction is arranged on the fixed pulley. The water level change information of the solar water heater is converted into the rotation information of the fixed pulley, and then the rotation distance of the fixed pulley is measured, therefore, the accurate measurement the water level of the solar water heater can be realized. As only the floater and patial thin lines in the water storage device of the solar water heater, the measurement accuracy is not affected or extremely weakly affected by the water quality, the temperature, the structure and other factors; the water storage device of the solar water heater does not need electric conduction, thereby avoiding electrolysis and other factors; compared with the traditional method, the measurement system has higher precision and is not affected by scaling and other factors; and the measurement device is mainly arranged outside the water storage device, so as to be convenient to realize maintenance and replacement.
Description
Technical field
The utility model relates to a kind of solar utilization technique, particularly a kind of solar water heater water level measurement system.
Background technology
The precision of solar water heater level measuring and stability are one of technical barriers in solar water heater design and the use.Consider the cost problem, the level measuring technology of solar water heater mainly is to use rustless metal rod or electric silica gel as conductor in the solar water heater accumulator at present, utilizes water level resistance measurement water level.Because there are the possibility of electrolysis in easy fouling of measurement component and water, so after water heater used a period of time, the precision of utilizing this method to measure water level will descend too much, thereby loses using value.Modes such as other utilizes pressure transducer in addition, weigh are measured the technology of water level, and these methods are implemented comparatively complicated, and all there are factors such as pressure fatigue in sensor, therefore use also to be restricted.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the solar water heater water level measurement system that a kind of measuring accuracy is not subjected to factor affecting such as water quality, temperature, structure.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of solar water heater water level measurement system, be characterized in: comprise a float in the accumulator that is placed on solar water heater, be connected with a rope yarn on the float, the other end of rope yarn links to each other with the object that dangles after by a fixed pulley, described fixed pulley and vertical object are arranged on the outside of accumulator, and the fixed pulley place is provided with the measurement mechanism that rotates the number of turns and rotation direction.
Water level changes, then float position changes, the rope yarn that links to each other with float drives fixed pulley and rotates, the measurement mechanism that assembles with fixed pulley is measured the rotation number of turns of fixed pulley, because the girth of fixed pulley is known and fixing, therefore after obtaining to rotate the number of turns, promptly know the change information of water level, thereby accurately determine water level.
The utility model compared with prior art, this system is converted into the rotation information of fixed pulley to the water level change information of solar water heater, measures the rotation distance of fixed pulley again, thereby has realized the accurate measurement of solar water heater water level.In the solar water heater accumulator, have only float and part fine rule, measuring accuracy is not subjected to the influence of factors such as water quality, temperature, structure or influences extremely faint; Do not need conduction in the solar water heater accumulator, avoided factors such as electrolysis; This measuring system is with respect to classic method, and precision improves, and is not subjected to factor affecting such as fouling, and measurement mechanism mainly is positioned at the accumulator outside, maintenance, change all more convenient.

Embodiment
A kind of solar water heater water level measurement system, comprise a float 2 in the accumulator 1 that is placed on solar water heater, top or upper lateral part perforate at accumulator 1, one end of rope yarn 3 be float 2, by the accumulator position of opening, link to each other with a pendle 6 through fixed pulley 4, described fixed pulley 4 and vertical object 6 are arranged on the outside of accumulator 1, and fixed pulley 4 places are provided with the measurement mechanism 5 that rotates the number of turns and rotation direction.Float 2 can float in the water, measures the rotation direction of fixed pulley and the upper and lower displacement amount that the number of turns is measured float by photoelectricity or other pick-up unit, thereby determines the water level in the solar water heater accumulator.
