Description

Technical Field

[0001] The present application relates to the technical field of solar heat collecting tubes, and in particular to a solar water heater heat collecting tube. Background Art

[0002] The solar water heater's collector tube is a pipe used to absorb solar energy and convert it into thermal energy. Usually, the collector tube is composed of a glass tube, a heat-absorbing plate and a heat-absorbing coating. The collector tube of a solar water heater absorbs the heat of sunlight and conducts it to the water or heat-conducting liquid in the tube, thereby raising the temperature and heating the water.

[0003] The solar water heater's collector tubes are mostly placed high on the roof to better receive solar energy. During the placement of the solar collector tubes, dust and dirt are easily accumulated on the surface of the collector tubes, affecting the heat absorption effect. For this reason, we adopt the method of regularly cleaning the solar collector tubes to improve the heat absorption effect.

[0004] At present, solar collector tubes are mostly cleaned manually using rags to wipe the surface of the solar collector tubes, so as to complete the cleaning without damaging the surface coating of the solar collector tubes. Soft brushes can also be used for cleaning. Since the solar collector tubes are laid over a large area, the cleaning efficiency is low. A solar water heater collector tube is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a solar water heater collector tube, which has the advantages of being easy to clean dust and dirt attached to the outer surface.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a solar water heater heat collecting tube, comprising a tube rack, on which a number of heat collecting tubes are evenly arranged, and a mounting frame for cleaning the heat collecting tubes is movably mounted on the tube rack;

[0007] A support frame is fixedly mounted on the inner side wall of the mounting frame, a mounting wheel is rotatably mounted between the supporting frames, and a soft brush is fixedly mounted on the inner wall of the mounting wheel;

[0008] The support frame includes two halves distributed on the inner side of the mounting frame, the two halves of the support frame are both arc-shaped, the outer wall of the mounting wheel is recessed toward the middle and is annular, the support frame is embedded in the annular recess and rotates relative to the mounting wheel, a transmission ring is fixedly installed on the outside of the mounting wheel, a transmission belt is sleeved between two adjacent transmission rings, and the adjacent transmission belts are staggered front and back and arranged outside the mounting wheel;

[0009] A mounting plate is fixedly mounted on one end of the mounting frame, a servo motor is fixedly mounted on the mounting plate, a rack is fixedly mounted on the outer surface of the mounting wheel located on one side, a gear is fixedly mounted on the output end of the servo motor, and the gear teeth are meshed with the rack.

[0010] Furthermore, a slide plate is fixedly installed between the upper and lower ends of the pipe rack, a slide frame is fixedly installed on the front of the mounting frame, and the slide frame is slidably connected to the slide plate.

[0011] Furthermore, a screw penetrating the sliding frame is threadedly mounted on the outside of the sliding frame.

[0012] Furthermore, handles are fixedly mounted on both sides of the mounting frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The solar water heater heat collecting tube is installed by sliding a mounting frame equipped with a plurality of mounting wheels on a tube frame, and the sliding direction of the mounting wheels is made consistent with the length direction of the heat collecting tube, so that when the mounting frame is moved, a plurality of mounting wheels can be pulled to slide relative to the heat collecting tube at the same time, that is, a plurality of heat collecting tubes can be cleaned at the same time by the soft brush on the inner side of the mounting wheel, and the mounting wheel can be rotated by arranging a transmission ring, a transmission belt and a servo motor for traction, thereby improving the cleaning efficiency of the soft brush.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-3 A solar water heater heat collecting tube in this embodiment includes a tube rack 1, on which a number of heat collecting tubes 2 are evenly arranged. The heat collecting tubes 2 have a built-in vacuum interlayer and are coated with an absorption coating for absorbing solar heat. A mounting frame 4 for cleaning the heat collecting tubes 2 is also movably installed on the tube rack 1.

[0021] In this embodiment, a slide plate 3 is fixedly installed between the upper and lower ends of the pipe rack 1, a slide frame 5 is fixedly installed on the front of the mounting frame 4, and the slide frame 5 is slidably connected to the slide plate 3. Through the mutual sliding of the slide frame 5 and the slide plate 3, the mounting frame 4 can slide toward the length direction of the heat collecting tube 2.

[0022] It should be noted that a screw 6 penetrating the sliding frame 5 is threadedly mounted on the outside of the sliding frame 5 , and the position of the sliding frame 5 on the sliding plate 3 can be limited by rotating the screw 6 , so as to fix the position of the mounting frame 4 in the storage state.

[0023] A support frame 8 is fixedly installed on the inner wall of the mounting frame 4 in this embodiment. The support frame 8 includes two halves distributed up and down on the inner side of the mounting frame 4. The two halves of the support frame 8 are both arc-shaped. A mounting wheel 9 is rotatably installed between the support frames 8. The inner diameter of the mounting wheel 9 is larger than the heat collecting tube 2, so that space can be reserved for installing cleaning tools.

[0024] In this embodiment, a soft-bristle brush 10 is fixedly mounted on the inner wall of the mounting wheel 9 , and the mounting wheel 9 can carry the soft-bristle brush 10 to clean the surface of the heat collecting tube 2 .

[0025] It should be noted that handles 7 are fixedly installed on both sides of the mounting frame 4, and the mounting frame 4 can be pulled and slid by the handles 7.

[0026] The outer wall of the mounting wheel 9 in this embodiment is recessed in the middle in a circular ring shape, and the support frame 8 is embedded in the circular ring recess and rotates relative to the mounting wheel 9, so that the rotation stability of the mounting wheel 9 is improved and the deviation of the mounting wheel 9 is reduced to scratch the surface coating of the heat collecting tube 2.

[0027] In this embodiment, a transmission ring 11 is fixedly installed on the outside of the mounting wheel 9, a transmission belt 12 is sleeved between two adjacent transmission rings 11, and adjacent transmission belts 12 are arranged front and back in an alternating manner on the outside of the mounting wheel 9, so that several mounting wheels 9 can complete synchronous rotation transmission.

[0028] It should be noted that a mounting plate 14 is fixedly mounted on one end of the mounting frame 4, a servo motor 15 is fixedly mounted on the mounting plate 14, a rack 13 is fixedly mounted on the surface of the mounting wheel 9 located on one side, a gear 16 is fixedly mounted on the output end of the servo motor 15, and the gear 16 is toothed in meshing engagement with the rack 13, and can be pulled by the servo motor 15 to rotate a mounting wheel 9.

[0029] The working principle of the above embodiment is:

[0030] When the heat collecting tube 2 needs to be cleaned, the screw 6 is rotated to loosen the contact with the slide plate 3, and then the servo motor 15 is turned on. The servo motor 15 drives the gear 16 on the output end to rotate, and the gear 16 is toothedly meshed with the rack 13, thereby driving a mounting wheel 9 to rotate. The mounting wheel 9 is driven by the cooperation between the external fixed transmission ring 11 and the transmission belt 12, so that several mounting wheels 9 rotate synchronously. At this time, the soft brush 10 on the inside of the mounting wheel 9 rotates with the mounting wheel 9, and the mounting frame 4 is driven to slide along the length direction of the heat collecting tube 2 by pulling the handle 7, so that the dust on the surface of the heat collecting tube 2 can be brushed and cleaned.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
