A kind of solar energy vacuum tube inner wall washing mechanism
Technical field
The present invention relates to solar water heater accessory technical field more particularly to a kind of solar energy vacuum tube inner wall washers
Structure.
Background technique
Vacuum tube solar heating element is the disadvantage is that the heat absorbing coating and water in solar energy vacuum tube after a period of use
Between heat exchanger effectiveness substantially reduce.The reason is that the impurity in tap water, which becomes scale after being heated, accumulates in solar energy vacuum tube
Inner wall on, so when solar energy evacuated inside pipe wall scale accumulation to a certain extent after will reduce between heat absorbing coating and water
Heat exchanger effectiveness, heat absorbing coating when scale is too thick on solar energy vacuum tube is and long-term because heat cannot distribute outward in time
Under this condition of high temperature, heat absorbing coating will fall off, to affect the collecting efficiency and service life service life of vacuum tube.

Gas vent slidably connects the magnetic scraping ring with its inner wall joint always in the solar energy evacuated tube body, and magnetism is scraped
Ring and magnetic sliding plug are attracting.
Preferably, the collar wall of the magnetic scraping ring is circumferentially with annular groove along it, is equidistantly equipped in the annular groove
Multiple connecting columns, the connecting column are connected on the inner wall of annular groove by spring, and the side wall of the connecting column is fixed to be connected
It is connected to arc scraper plate, and the outer wall of arc scraper plate and the inner wall of solar energy evacuated tube body offset, the solar energy vacuum tube sheet
It is coaxially provided with ball-screw in vivo, the ball-screw is fixed by the connecting rod the inner wall for being connected to solar energy evacuated tube body
On, feed screw nut is installed, the feed screw nut is fixedly connected on the interior of magnetic scraping ring by connector on the ball-screw
On wall.
Preferably, the end of the two neighboring arc scraper plate is equipped with mutually matched notch.
The invention has the following advantages:
1, low boiling point is irradiated to by glass plate to evaporate on liquid, and then makes low boiling point evaporation liquid gasification, evaporate in low boiling point
The promotion magnetic sliding plug of liquid moves up, and magnetic sliding plug is mobile to drive attracting magnetic scraping ring movement therewith, and then to solar energy
The scale of vacuum tube inner body wall carries out de-sludging, and other driving devices that no setting is required not only reduce the complexity of scale removal mechanism
Degree, while being also effectively reduced the consumption of the energy;
2, when moving, under the cooperation of feed screw nut and ball-screw, magnetic scraping ring can revolve magnetic scraping ring when moving up
Turn, arc scraper plate clears up the scale of solar energy vacuum tube inner body wall, under the action of the spring arc scraper plate always with
The inner wall of solar energy evacuated tube body pushes against, and the mode moved up in rotation keeps de-sludging more efficient;
3, rapid gas under the action of heat absorbing coating of the water in the inner wall gap of arc scraper plate and solar energy evacuated tube body
Change forms bubble and fast moves to two sides, and then washes away the dirt of solar energy vacuum tube inner body wall, improves scale removal effect.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Referring to Fig.1, a kind of solar energy vacuum tube inner wall washing mechanism, including solar energy evacuated tube body 1, feature exists
In the lateral wall of solar energy evacuated tube body 1 is radially connected with glass plate 2, and sliding chamber is equipped in glass plate 2, and cunning is intracavitary close
The sliding plug 3 that is magnetic that is slidably connected is sealed, the interior bottom of sliding chamber is equipped with low boiling point and evaporates liquid 4, and glass plate 2 uses convex lens, makes sunlight
