Description

Technical Field

[0001] This utility model belongs to the field of solar water heater technology, specifically relating to the protective structure of solar water heaters. Background Technology

[0002] Existing solar water heaters typically consist of a water tank, support rods, collector tubes, and brackets, utilizing solar energy for heating, making them energy-efficient and environmentally friendly. However, in actual use, especially under adverse weather conditions such as strong winds, rain, and snow, the collector tubes are easily affected by the external environment. On the one hand, strong winds may carry gravel and particles that impact the collector tubes, causing physical damage. On the other hand, snow accumulation on the collector tube surface during rain and snow makes cleaning difficult, and the snow also blocks sunlight, severely impacting the water heater's heat collection efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model designs a protective structure for solar water heaters to protect the heat collection tubes of solar water heaters. At the same time, it can quickly clear snow in rainy or snowy weather to prevent snow from covering the heat collection tubes for a long time, thereby ensuring the heat collection efficiency of the heat collection tubes.

[0004] This utility model discloses a protective structure for a solar water heater, comprising a water tank, support rods, collector tubes, and a bracket connecting the solar water heater body. The support rods are diagonally connected downwards on both sides of the water tank, and collector tubes are installed between the support rods and connected to the water tank. A bracket is connected downwards to the bottom of the water tank. A square protective frame is connected to the support rods, and a transparent protective cover is installed inside the protective frame to cover the upper part of the collector tubes. A cleaning rod is also installed on the transparent protective cover, longitudinally covering it. A slider at the top of the cleaning rod slides and engages with a groove at the top of the protective frame. The top of the cleaning rod is also threadedly connected to a lead screw. The lead screw is laterally connected between connecting seats on both sides of the top of the protective frame, and one end of the lead screw passes through the connecting seat and is connected to a handle.

[0005] The protective frame has connection holes on both sides of the frame and the outer end face of the support rod, and bolts are installed in the connection holes.

[0006] The contact surface between the cleaning rod and the transparent protective cover is made of rubber.

[0007] The cleaning rod is also connected to a crushing roller via a connecting plate. The crushing roller shaft passes through the connecting plate and is connected to a gear at its end. The gear is connected to a rack and pinion fixedly connected to the lower outer surface of the protective frame.

[0008] The bracket is L-shaped, with the top end of the bracket connected to the bottom of the water tank, the bottom end of the bracket connected to the bottom of the support rod, and a mounting base connected to the bottom of the bracket.

[0009] The beneficial effects of this utility model are:

[0010] Compared with existing technologies, the protective structure of this solar water heater protects the collector tubes by covering them with a transparent protective cover, preventing impact damage. A longitudinally extending cleaning rod is installed on the transparent protective cover. Driven by a screw, the cleaning rod moves laterally across the transparent protective cover, quickly clearing snow when it accumulates, facilitating cleaning and preventing prolonged snow accumulation on the collector tubes, thus ensuring the collector tubes' heat collection efficiency. Simultaneously, a crushing roller located on the side of the cleaning rod causes a gear connected to its shaft to slide on a rack as the cleaning rod moves laterally, causing the crushing roller to rotate and break up hard snow, resulting in better cleaning efficiency and effectiveness.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] See Figures 1 to 5 As shown, in this embodiment, a protective structure for a solar water heater is provided, comprising a water tank 1, support rods 2, heat collection pipes 3, and brackets 4 connected together to form the main body of the solar water heater. The support rods 2 are connected diagonally downward on both sides of the water tank 1, and heat collection pipes 3 are arranged between the support rods 2 and connected to the water tank 1. The brackets 4 are connected downward at the bottom of the water tank 1, and the whole structure constitutes the existing main body of the solar water heater.

[0022] To improve the protection of the solar water heater's collector tube 3, preventing physical damage and facilitating snow removal during severe rain and snow. A square protective frame 6 is connected to the support rod 2. The two sides of the protective frame 6 are provided with connection holes 601 corresponding to the outer end face of the support rod 2. Bolts 7 are installed in the connection holes 601 to fix the protective frame 6. A transparent protective cover 8 is installed inside the protective frame 6 to cover the upper part of the heat collection tube 3. The transparent protective cover 8 can not only provide protection, but also does not affect the absorption of solar energy by the heat collection tube 3. A cleaning rod 9 is also provided on the transparent protective cover 8, which is covered longitudinally. The top of the cleaning rod 9 is provided with a slider 901 that slides and engages with the slide groove 602 opened on the top of the protective frame 6. This restricts the movement of the cleaning rod 9, allowing it to move but not rotate. The top of the cleaning rod 9 is also threaded to a screw rod 10. The screw rod 10 is horizontally connected between the connecting seats 603 set on both sides of the top of the protective frame 6. One end of the screw rod 10 passes through the connecting seat 603 and is connected to a handle 11. When the transparent protective cover 8 is covered with snow, in order to enable the heat collection tube 3 to better absorb solar energy for heat collection, the screw 10 is rotated by the handle 11 so that the cleaning rod 9 scrapes across the transparent protective cover 8 to remove the snow on the transparent protective cover 8, which is convenient and quick.

[0023] To protect the transparent protective cover 8 from damage by the cleaning rod 9, a rubber layer 902 is provided on the contact surface between the cleaning rod 9 and the transparent protective cover 8, so that the cleaning rod 9 and the transparent protective cover 8 make a flexible contact.

[0024] In severe rainy or snowy weather, snow accumulation accompanied by a certain degree of icing can easily harden the snow piled on the transparent protective cover 8, making it difficult to remove by the cleaning rod 9 alone. Therefore, a crushing roller 12 is connected to the side of the cleaning rod 9 via a connecting plate 903. The shaft of the crushing roller 12 passes through the connecting plate 903 and is connected to a gear 13 at its end. The gear 13 is keyed to a rack 14 fixedly connected to the lower outer surface of the protective frame 6. As the cleaning rod 9 moves, the gear 13 at the end of the shaft of the crushing roller 12 slides on the rack 14, causing the crushing roller 12 to rotate, thus crushing and cleaning the hard snow, resulting in better cleaning efficiency and effectiveness.

[0025] Meanwhile, in this embodiment, in order to improve the installation stability of the solar water heater body, the bracket 4 is set as L-shaped, the top end of the bracket 4 is connected to the bottom of the water tank 1, the lower end of the bracket 4 is connected to the bottom of the support rod 2, and an installation base 5 is also connected to the bottom of the bracket 4, which is installed and fixed in the preset installation position by the installation base 5.

[0026] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
