Description

The broken leak-proof device of solar water heater vacuum-tube

Technical field

The utility model relates to solar water heater, is the broken leak-proof device of a kind of solar water heater vacuum-tube.

Background technology

Solar water heater is widely used, and all vacuum tubes of solar water heater are directly to be communicated with water tank all, and after arbitrary vacuum tube fragmentation wherein, the water in the water tank all can directly run off by broken vacuum tube.In order to address this problem, the solution that this area provides has two kinds: first kind of scheme is: parts such as seal cover are installed in the upper end at vacuum tube, ball float is installed in water tank, when ball float falls, seal cover is blocked, in case leak, why this scheme is not used more widely, be because its shortcoming is very obvious: because seal cover is contained in the vacuum tube upper end, when changing broken vacuum tube, parts such as seal cover need to move down the disengaging ball float with vacuum tube, this moment, the water in the water tank will flow out, and new vacuum tube can't accurately be installed in seal cover the vacuum tube upper end when installing; Second kind of scheme is: sealing ring is installed in water tank, the inwall of sealing ring contacts with vacuum tube, ball float is positioned at water tank, and ball float is connected with falling body by connecting rod, and this scheme finds that through installing and using its shortcoming is also very obvious: after the vacuum tube fragmentation, ball float falls to sealing vacuum tube, but still have the water outflow, can't realize sealing fully, can only reduce the speed that the water in the water tank flows out, and the other deficiency of this structure is the rate of heat exchange that influences the water in vacuum tube and the water tank.Therefore, present existing scheme can't really solve broken anti-the leaking of vacuum tube, particularly vacuum tube belongs to consumable accessory, because the broken water that runs off of vacuum tube is a kind of bigger wasting phenomenon, for water-deficient area and country, solve problem that the solar water heater vacuum-tube fragmentation leaks and be one of major subjects that those skilled in the art study.In addition, present solar water heater also can't can't reach the state of optimum utilization solar energy with sun seasonal variations, the different angles of regulating reflector of irradiating angle.

The utility model content

One of the purpose of this utility model provides the broken leak-proof device of a kind of solar water heater vacuum-tube, makes it solve the deficiency of known technology, really reaches when vacuum tube is broken, and the water in the water tank is enclosed in the water tank, does not have any loss; Two of purpose is, makes solar water heater can regulate the angle of solar energy reflector as required at any time, make regulate quick and easy.

The utility model for achieving the above object, be achieved through the following technical solutions: the broken leak-proof device of solar water heater vacuum-tube, comprise water tank and tank inner wall, offer through hole on the tank inner wall, vacuum tube is installed in the through hole, special-shaped cone seal is installed between tank inner wall and vacuum tube external wall of upper portion and in the vacuum tube cavity, abnormity cone seal is the integral type seal, conical through-hole is offered at abnormity cone seal middle part, abnormity cone seal is bending state, the outwards bending of abnormity cone seal major diameter part, outwards bending part is installed between tank inner wall and the vacuum tube, the outside bending part outer wall of abnormity cone seal and the outer wall of vacuum tube closely cooperate, the maximum gauge place outer wall of abnormity cone seal is provided with boss, offer draw-in groove on the boss, draw-in groove and tank inner wall closely cooperate, abnormity cone seal small diameter portion is installed in the cavity of vacuum tube inwall formation, installing connecting rods in the conical through-hole of abnormity cone seal, connecting rod one end is connected with ball float, the connecting rod other end is connected with guide rod on crossing the water piece, cross the water piece and be positioned at vacuum tube, cross the minimum outer diameter of the external diameter of water piece, cross on the water piece and offer at least one limbers greater than the thin end of conical through-hole.It is circular crossing the water piece, and guide rod is installed at the annulus middle part, and guide rod is connected with four dowels, forms a fan-shaped limbers between per two dowels.The major diameter part of the abnormity cone seal outwards height of bending is the 35-45 millimeter.Internal diameter suitable for reading after abnormity cone seal major diameter part outwards bends is the 40-42 millimeter, the minimum diameter that abnormity cone seal is installed in the small diameter portion in the vacuum tube is the 28-30 millimeter, the diameter of ball float is the 33-35 millimeter, and ball float and the distance of crossing between the water piece are the 30-40 millimeter.Water tank bottom is connected with travelling carriage, the inclined-plane of travelling carriage bottom contacts with guiding surface on the fixed support, the screw mandrel bearing is installed on guiding surface top, nut is installed in the guiding surface bottom, screw mandrel is installed in nut and the screw mandrel bearing, and reflector is installed on the fixed support, and is positioned at below the vacuum tube, reflector one end and travelling carriage one end are hinged by first hinge axis, and the reflector and the travelling carriage other end are by the second hinge axis hinge.

The utility model can solve the deficiencies in the prior art fully for the broken leakage-proof structure of the vacuum tube of finishing goal of the invention and providing.The cone-shaped hermetically-sealed construction of abnormity can play the sealing function between water tank and vacuum tube, can make ball float seal the bellmouth of special-shaped cone seal when vacuum tube is broken again, and the water in the water tank is not run off.Process test shows: after the vacuum tube fragmentation, water in the water tank is watertight, sealing effectiveness reaches optimum state, simultaneously, the sealing of water tank and vacuum tube also reaches fine state, the hydrothermal exchange of vacuum tube and water tank is not affected, rate of heat exchange with do not install before the broken leakage-proof structure identical.The broken leakage-proof structure of vacuum tube is easy to change vacuum tube, and when changing, the water in the water tank does not outflow, and vacuum tube replacing speed is fast etc.The adjustment reverse reflector structure of the utility model design, can make reflector with the sun different adjusting of irradiating angle in season, make the light application time of acceptance reach maximum states, this adjustment structure is regulated steadily than prior art, easy to adjust, and can realize angle free of discontinuities adjusting etc.
