Description

Solar water heater with grooved paraboloid

The utility model relates to a kind of solar water heater, particularly a kind of flute profile parabolic concentrator type solar water heater.

At present the solar water heater that generally uses all adopts flat-plate collector, and the energy density effect of flat-plate collector incident sunlight is bad, and have that the water route sealing effectiveness is bad, no antifreezing measures etc.

The purpose of this utility model is in order to overcome above-mentioned deficiency, a kind of energy density that improves incident sunlight to be provided, the flute profile parabolic concentrator type solar water heater that endothermic effect is good.

The purpose of this utility model is achieved in that it comprises framework, reflecting plate, water tank, pipeline, water pump, valve, solar tracking system, attemperating unit, its principal character is that pump links to each other with running water pipe with valve by pipeline, the hot water house steward is fixed on the framework, hot water house steward's a end is equipped with temperature sensor, temperature sensor links to each other with temperature controller, solar absorber is equipped with in the upper end of reflecting plate, reflecting plate is installed on the support of bearing, the support of bearing and framework are installed as one, drive the rotation of reflecting plate by the rotation of motor and chain drum, thereby realize the reflecting plate tracking sun, the light focusing that makes reflecting plate is on absorber.

Do the embodiment explanation below in conjunction with accompanying drawing.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a schematic diagram of the present utility model.

Fig. 3 is a water route of the present utility model joint sealing structure chart.

Fig. 4 is an attemperater structure chart of the present utility model.

Fig. 5 is a solar tracking system block diagram of the present utility model.

By Fig. 1,2 as can be known, pump 3 is by pipeline and valve 1, valve 2 links to each other with running water pipe, reflecting plate 8 is installed on the support of bearing 19, the reflecting plate skeleton is 20, reflecting plate 8 is flute profile parabolic concentrator type, parabolic opening B 〉=800mm, parabolic skeleton is by fiberglass and metal manufacturing, the reflecting surface material is made by thickness T 〉=0.5mm polishing stainless steel plate, it is glass-vacuum tube that solar absorber 7(absorber is housed in the upper end of reflecting plate 8), the water route sealing of glass-vacuum tube is adopted overall plastic three-layer sealed, it also can be black copper matter pipe, hot water house steward 9 is fixed on the framework 21, the framework 21 and the support of bearing 19 are installed as one, hot water house steward's a end is equipped with temperature sensor, temperature sensor links to each other with temperature controller, on temperature controller, can control the temperature of water, the flow of hot water that hot-water line 9 flows out is gone into water tank 10, direct current generator 6 is by chain 22, chain drum 23 drives the rotation of control reflecting plate 8, luminous energy sensor 25 picks up the energy (the luminous energy sensor is a plurality of compositions) of light, and drive system 26 provides signal by pursuing into, thereby makes the rotation that drives direct current generator realize following the tracks of the sun, and power supply 24 is powered to said system.

As shown in Figure 3, the water route joint sealing system is made of tube connector 27, R type rubber cushion 28, O shape circle 29, plastic tubulature 30, screw thread vinyl cover 31, glass-vacuum tube 7.By adjusting screw thread vinyl cover 31, O shape circle 29 is locked with glass-vacuum tube 7 is one, R type rubber cushion 28 and O RunddichtringO 29 seal.Constitute overall plastic three-layer sealed thus.

As shown in Figure 4, attemperater 10 be by overlap 32 in the fiberglass, infrared coating 33, polyurethane 34, infrared coating 35, iron plate overcoat 36 constituted.Because infrared coating has reflex to heat, so when the heat of water in the water tank when fiberglass reaches infrared coating, infrared coating reflects back it, the heat that partial reflection is gone back insulated body when infrared coating conducts to heat guard stops, even the minimum heat that heat guard can not stop, also returned by second layer infrared coating,---heat guard---far infrared thermal insulation layer can drop to bottom line to the heat loss of water in the water tank so far infrared.

As shown in Figure 5, luminous energy sensor 25 picks up solar energy, and during light direct projection sensor 25a, sensor 25a, 25b, the capacitation of 25c, 25d institute equate that drive system 26 drives motor 6 rotations by pursuing into, is output as zero, the motor stall.When non-rectilinear, just changeing during 25c during 25a＞25b＞25d, otherwise counter-rotating forwards to when equating, be output as zero, the motor stall, so circulation, from sun to sun.

Operation principle

(1), water on the blank pipe

A, when electricity is arranged: K2 and A close a floodgate, and adjust and set button promptly: water enters water tank 10 by valve 2 → pump 3 → check valve 4 → absorber 7 → hot-water line 9, stop to go up water during to the F line, arrive set button adjusting temperature required.

B, when not having electricity: K2 and A close a floodgate, and open ball valve 1, that is: water enters water tank by valve 1 → pump 3 → check valve 4 → absorber 7 → water heater 9 → water tank 10, stop to go up water during to the F line, close ball valve 1, arrive the setting button adjusting temperature required.

(2), the method for operation

A, constant temperature operation

Temperature indicating controller (TIC) is set button, be transferred to needed temperature (as 50 ℃), because temperature-sensing probe (sensor) C point and hot water house steward link, so when temperature reaches design temperature, sensor sends signal, A.C. contactor action in the control cabinet is connected K1, K3, magnetic valve, pump work are squeezed into water heater with water, when C place temperature was reduced to 40 ℃, sensor sent signal again, and contactor discharges voluntarily, make K1, K3 dump, magnetic valve, pump quit work, and circulation and so forth makes the interior hot water of water tank increase to specified volume gradually.

B, circular flow

By water on above-mentioned (1) a blank pipe, close a floodgate filling a certain amount of water (requirement) K2 and A in the water tank 10, set button adjusting to temperature required, K3 opens (out of hand), open ball valve 11, when water heater was raised to design temperature, promptly water had following cyclic water tank 10 → ball valve 11 → pump 3 → check valve 4 → absorber 7 → hot-water line 9 → water tank 10.

(3), antifreezing measures

A, open ball valve 5 and the water in the hot water pipeline is all entered water tank 10 close ball valve 5 then.

B, when temperature indicating controller (TIC) is set to 5 ℃, sensor sends signal, K1 power connection, pump work, the hot water of water tank is squeezed on the water heater, and when E place water temperature reached 15 ℃, sensor sent signal, cuts off the electricity supply, stop to go up water, circulation and so forth, thereby anti-locking system bursting by freezing.

(4), water method

Open ball valve 12, shower nozzle 13 promptly has the hot water ejection.

The utility model has the advantages that: improved the energy density of incident sunlight, endothermic effect is good, and the water route sealing is advanced, and antifreezing measures are superior.
