Technical Field
[0001] The utility model belongs to the technical field of solar water heaters, and more specifically, particularly relates to a medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type. Background Art
[0002] At present, when installing heat collecting tubes in a solar water heater, the heat collecting tubes are usually directly inserted into the holes pre-retained in the water heater, and the reflecting plates used on the solar water heater are aluminum sheets, embossed aluminum sheets, etc. laid on the sun-shaded side of the vacuum heat collecting tube to reflect sunlight to the sun-shaded side of the vacuum heat collecting tube, thereby enhancing the light-concentrating and heat-collecting efficiency of the true heat collecting tube.
[0003] Based on the above, the inventor found the following problems: However, in order to facilitate installation and subsequent thermal expansion, the holes are generally larger than the heat collecting tubes, resulting in the heat collecting tubes being prone to collision and breakage when shaken by external influences. Moreover, there are certain drawbacks in using reflecting plates. Firstly, the materials are prone to oxidation. Secondly, in places with strong winds or many typhoons, they are deformed under the action of wind, affecting the reflecting effect.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type is provided, in order to achieve a more practical value purpose. Content of the Utility Model
[0005] In order to solve the above technical problems, the utility model provides a medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type to solve the existing problems.
[0006] The utility model provides a medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type, which is achieved by the following specific technical means:
[0007] A medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type includes an outer tube body and an inner tube body. Arc-shaped ends are fixed at both ends of the outer tube body. Rubber rings are arranged on the outer walls of the two arc-shaped ends. One end of one of the arc-shaped ends is in a sealed hemispherical shape. A spring is fixed at one end of this arc-shaped end. A connecting block is fixed at one end of the spring. A connecting pipe is fixed at one end of the other arc-shaped end. A fixing ring is fixed on the outer wall of one end of the connecting pipe. A limiting rod is hinged on the outer wall of the fixing ring. A rubber pad is fixed on the side of the limiting rod away from the connecting pipe.
[0008] Further, the limiting rod is arranged in a curved shape. There are multiple limiting rods, and the multiple limiting rods are arranged at equal circumferential intervals. The rubber pad is arranged in an isosceles trapezoid shape.
[0009] Further, the diameter value of the connecting block is smaller than the diameter value of the connecting pipe.
[0010] Furthermore, the outer wall diameter values of both of the arc-shaped ends are smaller than the outer wall diameter value of the outer tube body, and both of the rubber rings are arranged in a hollow frustum shape.
[0011] Furthermore, the outer tube body and the inner tube body are hermetically connected near one end of the connecting tube, and a heat absorption film is plated on the outer wall of the inner tube body.
[0012] Furthermore, a reflection coating is arranged on the inner wall of the outer tube body. The reflection coating is arranged on the sun-shaded side of the outer tube body, and the sun-shaded side of the inner tube body is close to the reflection coating.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. When one end with the fixing ring is inserted into the hole reserved in the solar water heater bracket in the utility model, the curved limiting rod will squeeze the edge of the hole, causing the side with the rubber pad to tilt upwards around, making the connection between the end with the fixing ring and the water heater bracket closer. By the spring releasing elastic potential energy, the end with the fixing ring can fit with the water heater bracket, and the rubber ring fills the gap between the arc-shaped end and the water heater bracket, thus achieving the effects of convenient installation and not being easily broken when shaken by external forces.
[0015] 2. In the utility model, the reflective layer is plated on the inner wall of the outer tube. It is in a vacuum environment, so it is not affected by wind and rain, will not be oxidized by air, will not produce noise, will not be contaminated with dust, has a long service life, is safe, beautiful, and has a low cost. The reflection ability of the reflective layer will not be affected by the surrounding environment either. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following further describes in detail the implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0023] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more; in addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0024] Embodiment:
[0025] As shown in the attached Figure 1 to the attached Figure 4 figures:
[0026] The present utility model provides a medium-temperature heat collecting tube of an internally concentrating and eccentric vacuum tube type, which includes an outer tube body 1 and an inner tube body 2. Arc-shaped ends 4 are fixed at both ends of the outer tube body 1. Rubber rings 9 are arranged on the outer walls of the two arc-shaped ends 4. One end of one of the arc-shaped ends 4 is in a sealed hemispherical shape. A spring 10 is fixed at one end of this arc-shaped end 4. A connecting block 11 is fixed at one end of the spring 10. A connecting pipe 5 is fixed at one end of the other arc-shaped end 4. A fixing ring 6 is fixed on the outer wall of one end of the connecting pipe 5. A limiting rod 7 is hinged on the outer wall of the fixing ring 6. A rubber pad 8 is fixed on the side of the limiting rod 7 away from the connecting pipe 5.
[0027] Among them, the limiting rod 7 is arranged in a bent shape. A plurality of limiting rods 7 are arranged in a circumferential equidistant arrangement. The rubber pad 8 is arranged in an isosceles trapezoid shape. When inserting the end with the fixing ring 6 into the hole reserved in the solar water heater bracket, the bent limiting rod 7 will squeeze the edge of the hole, causing the side with the rubber pad 8 to warp around. The deeper the fixing ring 6 enters the hole, the greater the squeezing degree of the rubber pad 8, making the connection between the end with the fixing ring 6 and the water heater bracket tighter.
[0028] Among them, the diameter value of the connecting block 11 is smaller than the diameter value of the connecting pipe 5, so that the end with the spring 10 and the connecting block 11 can easily enter the hole on the other side of the water heater. By releasing the elastic potential energy of the spring 10, the end with the fixing ring 6 can be fitted with the water heater bracket.
[0029] Among them, the outer wall diameter values of the two arc-shaped ends 4 are both smaller than the outer wall diameter value of the outer tube body 1. The two rubber rings 9 are both arranged in a hollow frustum shape. The arranged arc-shaped ends 4 enable the outer tube body 1 to better connect with the hole in the water heater, and the rubber rings 9 are used to fill the gap between the arc-shaped ends 4 and the water heater bracket.
[0030] Among them, the outer tube body 1 and the inner tube body 2 are sealed and connected near one end of the connecting tube 5. The outer wall of the inner tube body 2 is coated with a heat-absorbing film. The heat-absorbing film can better absorb heat, which is convenient for vaporization inside the inner tube body 2. The outer tube body 1 and the inner tube body 2 are sealed to prevent the internal heat-absorbing film and the reflective coating 3 from being oxidized.
[0031] Among them, the inner wall of the outer tube body 1 is provided with a reflective coating 3, and the reflective coating 3 is arranged on the non-sunny side of the outer tube body 1. The non-sunny side of the inner tube body 2 is close to the reflective coating 3. Through the reflective coating 3 arranged inside, sunlight can be reflected to the outside of the inner tube body 2 to improve lighting.
[0032] The specific usage and function of this embodiment are as follows:
[0033] In the present invention, when the end with the fixing ring 6 is first inserted into the hole reserved in the bracket of the solar water heater, the curved limiting rod 7 will squeeze the edge of the hole, so that the side with the rubber pad 8 will be tilted to the surroundings. The deeper the fixing ring 6 enters the hole, the greater the degree of squeezing of the rubber pad 8, so that the connection between the end with the fixing ring 6 and the water heater bracket is tighter. The diameter value of the connecting block 11 is smaller than the diameter value of the connecting pipe 5, so that the end with the spring 10 and the connecting block 11 can easily enter the hole on the other side of the water heater, and the elastic potential energy is released by the spring 10, so that the end with the fixing ring 6 and the water heater bracket can be easily inserted into the hole on the other side of the water heater. One end with a fixing ring 6 can fit with the water heater bracket, and the arc-shaped end 4 is set so that the outer tube body 1 can be better connected to the hole between the water heater, and the gap between the arc-shaped end 4 and the water heater bracket is filled by the rubber ring 9. When in use, the heat-absorbing film can better absorb heat, which is convenient for vaporization inside the inner tube body 2, and the outer tube body 1 and the inner tube body 2 are sealed to prevent the internal heat-absorbing film and the reflective coating 3 from being oxidized. The reflective coating 3 set inside can reflect sunlight to the outside of the inner tube body 2 to improve the lighting and the heat collection efficiency of the heat collecting tube.
[0034] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
