Abstract

The utility model relates to an electrically adjusting type support of a solar-energy water heater, which relates to a bottom support, a vertical support and a slanting support. The bottom support and the vertical support are fixed together, and the vertical support and the upper end of the slanting support are hinged together. A rotating shaft is supported on the bottom support by a bearing seat. Both ends of the rotating shaft are fixed with gears. The middle part of the rotating shaft is fixed with a worm wheel. A worm screw is supported on the bottom support by a support seat. The worm screw is engaged with the gears. A motor is fixed on the bottom support. The end of the worm screw is connected with an output shaft of a motor through a friction coupling. Gear racks are fixed on both sides of the lower part of the slanting support. One end of each gear rack is fixed on the frame of the slanting support. The two gear racks are respectively engaged with the gears at both ends of the rotating shaft. When the support can adjust the elevation angle of a heat absorption device, the running of the motor is controlled by a circuit. The remote control can be realized, and the adjustment is convenient and quick. The utility model can be matched with a position or angle monitoring device and a control circuit for realizing angle automated adjustment. The perpendicular angle between the heat absorption device and solar light can be automatically held, and the automated adjustment is achieved.

Description

Solar water heater electric is adjusted support

Technical field:

The utility model relates to a kind of solar water heater adjustable support, especially can adjust the electronic adjustment support at the solar water heater heat-absorbing device elevation angle.

Background technology:

The rack of solar water heater of selling on the market is generally the stationary structure that can not adjust the solar water heater heat-absorbing device elevation angle, be that the dull and stereotyped angle with the solar light irradiation angle of endothermic tube or heat absorption is unadjustable, like this in different latitude, Various Seasonal and the intraday different moment, angle between heat-absorbing device and the sunshine is immutable, can not make heat-absorbing device keep vertical or near normal state, greatly reduce endothermic effect with sunray; A kind of solar water heater adjustable support is disclosed in Chinese patent ZL03253579.1, can regulate the angle of heat-absorbing device and ground level, need carry out manually, regulate trouble but regulate, be not easy to regulate at any time, can not make solar water heater reach best endothermic effect.

Summary of the invention:

The purpose of this utility model provides a kind of solar water heater electric and adjusts support, can far distance controlled or automatically control the solar water heater heat-absorbing device elevation angle on the support is adjusted, can be in good time or adjusting automatically, easy to adjust.

The purpose of this utility model realizes as follows: this solar water heater electric is adjusted support and is related to underframe, stand and oblique frame, underframe and stand are fixed together, the upper end of stand and oblique frame is hinged, on underframe, support a rotating shaft with bearing block, the two ends fixed gear of rotating shaft, fixed motor on underframe, the outputting power of motor is connected with rotating shaft, in oblique both sides, frame bottom stationary rack, the gears engaged that two tooth bars are corresponding with the rotating shaft two ends respectively.Motor can be selected small-sized low-speed DC motor, rotating by motor drives the rotating shaft rotating, gear driven tooth bar in the rotating shaft can be realized moving back and forth, thereby the oblique frame of rack drives is swung around itself and the hinge point of stand, the heat-absorbing device of device on oblique frame tried one's best and sunshine maintenance vertical relation, improve heat absorption efficiency.

Actuating unit structure on from the motor to the rotating shaft is: fixing worm gear in rotating shaft, on underframe by the seat supports worm screw, the worm and wheel engagement, the end of worm screw is connected with motor output shaft by shaft coupling.The rotary power of motor passes to worm screw through shaft coupling like this, and slowing down to increase through worm and gear again passes to rotating shaft after turning round.

Shaft coupling selects the friction limit to turn round shaft coupling, when the power that transmits surpasses design load, the output shaft of shaft coupling skids with respect to the importation, stops outputting rotary power backward, avoids a level running part in back to move to and damages drive disk assembly when extreme position or transmission are obstructed.

The limit switch of restriction tooth bar range is housed respectively at the two ends of tooth bar, and when tooth bar end during near gear, limit switch action, the motor outage stops to continue operation, plays the safeguard protection effect.

This solar water heater electric is adjusted support, when adjusting the elevation angle of heat-absorbing device, by the circuit controling motor running, can realize far distance controlled, and is easy to adjust, quick; If cooperation position or angle monitor device and control circuit can realize that angle adjusts automatically, keep the heat-absorbing device angle vertical automatically with sunshine, realize adjusting automation.

Description of drawings:

Fig. 1 is the front view that the utility model solar water heater electric is adjusted support.

Fig. 2 is that K among Fig. 1 is to partial view.

Fig. 3 is the topology view of gear and tooth bar mate.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, this support relates to underframe 6, stand 4 and oblique frame 14, tiltedly solar energy heat absorbing devices such as endothermic tube or heat absorption flat board are placed on the plane at frame 14 places, it shown in Fig. 1 endothermic tube 13, tiltedly frame 14 tops have a concave surface to be used to place solar water heater water tank 1, and underframe 6 and stand 4 are fixed together, and being connected and fixed bar 3 between underframe 6 and stand 4 increases rigidity, stand 4 is used for the weight of support solar water-heater water tank 1 and oblique frame 14 grades, and underframe 6 is as the collet of entire bracket.The upper end of stand 4 and oblique frame 14 is hinged by bearing pin 2, on underframe 6 with bearing block 18 and bearings one rotating shaft 16 that includes, the two ends fixed gear 17 of rotating shaft 16, the fixing worm gear 8 at rotating shaft 16 middle parts, on underframe 6 by bearing 10 and the bearings worm screw 9 that includes, worm screw 9 and worm gear 8 engagements, fixed motor 5 on underframe 6, the end of worm screw 9 is turned round shaft coupling 7 by the friction limit and is connected with motor 5 output shafts, at oblique both sides, frame 6 bottom stationary rack 11, one end of tooth bar 11 is fixed on oblique frame 14 frames, the other end of tooth bar 11 and tiltedly between frame 14 frames fixedly bracing piece 15 tooth bar 11 is securely fixed on the oblique frame 14, two tooth bars 11 respectively with gear 17 engagements at rotating shaft 16 two ends.The limit switch 12 of restriction tooth bar 11 ranges is housed respectively at the two ends of tooth bar 11, and when tooth bar 11 ran to extreme position, limit switch 12 touched rotating shaft and moves, and sent power-off signal for motor 5, played the safeguard protection effect.
