All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, a heat collecting tube for a solar water heater convenient to maintain includes a solar support 1, the top end of the solar support 1 is movably connected with a heat collecting tube 2, the top end of the heat collecting tube 2 is movably connected with a heat preservation water storage barrel 3, the middle of the heat preservation water storage barrel 3 is fixedly connected with an outer barrel plate 4, the front of the outer barrel plate 4 is fixedly provided with a spring 5, one end of the spring 5 is fixedly connected with a sliding block 6, the top end of the middle of the sliding block 6 is provided with a water circulation port 7, the outer side surface of the sliding block 6 is provided with a tooth socket 8, and is movably connected with a gear 9 through the tooth socket 8, the middle of the gear 9 is movably connected with a rotating shaft 10, and the middle of the rotating shaft 10 is movably connected with a fan blade 11.
The width of hydrologic cycle mouth 7 is unanimous with the length of 3 top diameters of heat preservation water storage bucket, the width of slider 6 is greater than the length of 3 top diameters of heat preservation water storage bucket, and it is little than the central axis distance of two heat preservation water storage bucket 3, complementary influence between the slider 6 on 3 tops of every heat preservation water storage bucket has been guaranteed, and slider 6 moves down to 3 tops of heat preservation water storage bucket just when just to hydrologic cycle mouth 7, the width of hydrologic cycle mouth 7 can ensure that the water in the heat preservation water storage bucket 3 normally circulates in thermal-collecting tube 2, slider 6 is the arc, can reciprocate in outer tube sheet 4, outer tube sheet 4 just has seted up the opening to 3 top open-ended positions of heat preservation water storage bucket, when slider 6 moves down to the bottom, the water that is heated in the thermal-collecting tube 2 can rise along the pipe and get into in the heat preservation water storage bucket 3 through the opening on hydrol.
The rotating shaft 10 is fixedly arranged at the top end of the heat-preservation water storage barrel 3, the gear 9 is fixedly connected with the fan blade 11, and the gear 9 and the fan blade 11 are movably sleeved in the middle of the rotating shaft 10, under the condition of strong solar radiation in fine days, the heat collection pipe 2 with strong heat transfer performance absorbs the heat radiated by the sun and transfers the heat to the water in the heat collection pipe 2 to heat the heat, because the thread of the heat-preservation water storage barrel 3 ensures that the heat-preservation water storage barrel 3 is in a screwed state, the rotating shaft 10 is in a horizontal state, when the heated hot water floats upwards and flows into the heat-preservation water storage barrel 3 through the through hole, the water flow pushes the fan blade 11 on the upper side to rotate rightwards, the cold water sinks to flow down from the lower side to the heat collection pipe 2 to be heated, the water flow pushes the fan blade 11 on the lower side to rotate leftwards, the water circulation in the pipe pushes the fan blade 11 to rotate clockwise, the fan blade 11 is fixedly connected with the gear 9, so as to drive the gear 9 to rotate clockwise, thereby the slide block 6 to move downwards to completely open the water flow channel by stirring the tooth groove 8, ensuring the water circulation heating in sunny days.
At night or in rainy weather, no sun or weak solar radiation exists, the heat collecting tube 2 can not absorb a large amount of heat, hot water can not rise in the heat collecting tube, no water circulation is generated, the gear 9 keeps static at the moment, when the gear 9 is static, the sliding block 6 is only positioned at the top end of the outer tube plate 4 under the action of the spring 5, and the top surface of the sliding block 6 is provided with a sealing rubber sheet, so that the water flow rate between the heat collecting tube 2 and the heat-preservation water storage barrel 3 is reduced, and the phenomenon that the hot water in the heat-preservation water storage barrel 3 is dissipated more heat through the heat collecting tube 2 at night to cause resource waste is avoided.
Wherein, one side of the top end of the heat preservation and water storage barrel 3 is provided with a bulge, under the state that the heat collecting pipe 2 and the heat preservation and water storage barrel 3 are installed, the convex top sliding block 6 ensures that an opening with the length of one fourth of the diameter width of the heat collecting tube 2 is always arranged between the heat collecting tube 2 and the heat preservation water storage barrel 3, so that when the night is finished, the heat collecting pipe 2 starts to absorb heat, the water can rise to the heat-preservation water storage barrel 3 to form water flow to push the (11) to rotate, thereby gradually opening the sliding blocks 6 to carry out water circulation heating with maximum efficiency, and when the scale in the heat collecting pipe 2 needs to be cleaned and maintained, only need take off thermal-collecting tube 2, the slider 6 that does not receive the protruding top of thermal-collecting tube 2 top to move receives the thrust of spring 5 to seal the opening totally, has realized need not to keep warm and store water in the water bucket 3 and all discharge alright clear up the maintenance to thermal-collecting tube 2, greatly reduced the complexity of maintaining and reduced the waste of water resource.
The use method (working principle) of the invention is as follows:
when the device is used, the device is placed in a place with high sunshine rate, cold water is filled in the heat-preservation water storage barrel 3, the heat collection tube 2 absorbs heat radiated by the sun and transfers the heat to the cold water in the tube, so that the cold water is heated, hot water in the heat collection tube 2 floats upwards from the fan blade 11 and flows into the heat-preservation water storage barrel 3 and pushes the fan blade 11 to rotate clockwise, cold water in the heat-preservation water storage barrel 3 sinks and flows into the heat collection tube 2 from the lower part to be heated in a water circulation mode, the fan blade 11 rotates clockwise under the action of the water circulation and drives the gear 9 to rotate, the gear 9 pushes the tooth socket 8 to enable the sliding block 6 to compress the spring 5 to move downwards, a water circulation port is completely opened, the heating of the water in the heat-preservation water storage barrel 3 is accelerated, when the solar radiation is weakened at night, the heat collection tube 2 stops heating the water in the tube, and the heat-preservation water storage barrel 3 have a small temperature difference, the water circulation is weakened, at the moment, the water flow which pushes the fan blades 11 to rotate is reduced and is not enough to compress the spring 5, so that the spring 5 drags the sliding block 6 to move upwards to seal the channel between the heat collecting pipe 2 and the heat preservation and water storage barrel 3, and only the small starting opening maintained by the bulge on the heat collecting pipe 2 flows, thereby greatly reducing the degree of water temperature in the heat preservation and water storage barrel 3 losing from the heat collecting pipe 2 at night and reducing the waste of heat; when the incrustation scale that stores up in the thermal-collecting tube 2 needs to be cleared up or maintain, take off thermal-collecting tube 2 self preservation temperature retaining bucket 3 department, the arch on thermal-collecting tube 2 top no longer presses the slider 6 and remains the start-up mouth simultaneously, slider 6 shifts up with the opening totally closed by spring 5 elasticity, make retaining can not flow in the thermal-insulating retaining bucket 3, and the thermal-collecting tube 2 of the single thermal-collecting tube 2 both sides of taking off still normally works, rivers in the thermal-insulating retaining bucket 3 are to the relative negative pressure of formation of the flow of both sides thermal-collecting tube 2 department, guaranteed that take off thermal-collecting tube 2 department can not have rivers to spill, realized need not the drainage alright clear up the purpose of maintaining, make the maintenance more convenient.
