Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and more specifically, to a solar centralized heating device. Background Technology

[0002] A solar collector is a device that converts solar radiation into heat energy. Because solar energy is relatively dispersed, it is necessary to find ways to concentrate it; therefore, solar collectors are a key component of various solar energy utilization devices.

[0003] Traditional solar district heating systems have the following drawbacks: They typically require installation in locations with good sunlight. They heat water within vacuum tubes by absorbing heat, and then store the hot water. However, during hot summer months, when the system is not activated, the lack of water in the vacuum tubes leads to excessively high temperatures. This can cause the heat exchange medium inside the collector to vaporize, resulting in the system being exposed to direct sunlight or damage to components. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a solar centralized heating device with the advantage of protecting the vacuum tube.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar centralized heating device, comprising a solar collector, an auxiliary mechanism provided at the rear of the solar collector, the solar collector including a heat pipe, a vacuum tube uniformly fixedly installed below the heat pipe, a circulation pipe fixedly installed below the vacuum tube, a water inlet pipe fixedly installed at the right end of the heat pipe, the auxiliary mechanism including a platform fixedly installed at the rear of the heat pipe, a groove provided on the inner side of the platform, a round rod rotatably installed inside the groove, a long plate located above the heat pipe provided at the front of the platform, a shielding cloth uniformly wrapped around the outside of the round rod fixedly installed at the rear of the long plate, a fixing block two fixedly installed above the right end of the circulation pipe, a screw extending into the inner side of the platform fixedly installed at the front end of the fixing block two, the right end of the long plate movably sleeved on the outside of the screw, a servo motor two fixedly installed at the rear of the fixing block two, the output end of the servo motor two fixedly installed at the rear end of the screw.

[0006] As a preferred embodiment of this utility model, a connecting plate is uniformly fixedly installed below the long plate, and a cleaning ring is fixedly installed below the connecting plate.

[0009] As a preferred embodiment of this utility model, a rectangular plate is fixedly installed inside the groove, and a rectangular hole is opened on the surface of the rectangular plate, which corresponds to the shielding cloth.

[0010] As a preferred embodiment of this utility model, limit rings are fixedly installed on the outer sides of both ends of the round rod, and an arc-shaped groove is formed on the inner side of the limit ring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a solar centralized heating device, including a solar collector 1, an auxiliary mechanism 2 arranged at the rear of the solar collector 1, a heat pipe 11, vacuum tubes 16 uniformly fixedly installed below the heat pipe 11, a circulation pipe 15 fixedly installed below the vacuum tubes 16, and a water inlet pipe 17 fixedly installed at the right end of the heat pipe 11. The auxiliary mechanism 2 includes a platform 201 fixedly installed at the rear of the heat pipe 11, a groove 202 is formed on the inner side of the platform 201, and a round rod 203 is rotatably installed inside the groove 202. A long plate 209 is provided on the front side of the platform 201 above the heat pipe 11. A shielding cloth 210 is fixedly installed on the rear side of the long plate 209 and evenly wrapped around the outside of the round rod 203. A fixing block 215 is fixedly installed above the right end of the circulation pipe 15. A screw 218 extending to the inside of the platform 201 is fixedly installed at the front end of the fixing block 215. The right end of the long plate 209 is movably sleeved on the outside of the screw 218. A servo motor 216 is fixedly installed on the rear side of the fixing block 215. The output end of the servo motor 216 is fixedly installed at the rear end of the screw 218.

[0023] When it is necessary to shade the vacuum tube 16, the second servo motor 216 is started, which drives the screw 218 to rotate. The rotation of the screw 218 drives the long plate 209 to move downward along the long rod 217, so that the long plate 209 pulls the shading cloth 210 out from the inside of the platform 201. The round rod 203 rotates to release the shading cloth 210, so that the shading cloth 210 shades the vacuum tube 16. When it is necessary to retract, the second servo motor 216 drives the screw 218 to rotate in the opposite direction. At this time, the first servo motor 208 drives the round rod 203 to rotate in the opposite direction, so that the shading cloth 210 is wrapped around the outside of the round rod 203 through the rectangular hole 207. The arc groove 205 assists in the wrapping of the shading cloth 210.

[0024] By activating the servo motor 216, the screw 218 rotates, causing the long plate 209 to move downwards along the long rod 217, so that the shielding cloth 210 shields the vacuum tube 16. Compared with traditional solar centralized heating devices, this solar centralized heating device effectively protects the vacuum tube 16 by shielding it with the shielding cloth 210, preventing the medium inside the vacuum tube 16 from vaporizing due to high summer temperatures, which could lead to system overheating or component damage, and thus improving the service life of the vacuum tube 16.

[0025] Among them, a connecting plate 211 is evenly fixedly installed below the long plate 209, and a cleaning ring 212 is fixedly installed below the connecting plate 211. The cleaning ring 212 corresponds to the vacuum tube 16, and a brush 213 is evenly fixedly installed on the inner side of the cleaning ring 212.

[0026] When it is necessary to clean the vacuum tube 16, simply use water to clean the dust on the surface of the vacuum tube 16, and then start the servo motor 216 to make the long plate 209 move downward under the limit of the long rod 217, thereby driving the connecting plate 211 to move downward, and the connecting plate 211 to drive the cleaning ring 212 to move downward around the vacuum tube 16, thereby cleaning and wiping the surface of the vacuum tube 16 through the brush 213, effectively reducing the accumulation of dust.

[0027] By cleaning the dust off the surface of the vacuum tube 16 with water, and then starting the servo motor 216, the surface of the vacuum tube 16 is cleaned and wiped by the brush 213. Compared with traditional solar centralized heating devices, this solar centralized heating device continues to clean the surface of the vacuum tube 16 by brush 213, thereby effectively preventing dust from accumulating on the surface of the vacuum tube 16 and affecting the heat collection effect, and making it easy to use.

[0028] A bracket 12 is fixedly installed below the heat pipe 11, and fixing plates 13 extending to both sides of the circulation pipe 15 are fixedly installed on both sides of the heat pipe 11. A base plate 14 is fixedly installed on the inner side of the front end of the fixing plate 13.

[0029] The solar collector 1 is supported by the bracket 12 and the fixing plate 13, thereby improving the stability of the installation of the solar collector 1.

[0030] Among them, a servo motor 208 is fixedly installed on the outer side of the platform 201, and the output end of the servo motor 208 is fixedly installed at the front end of the round rod 203.

[0031] Servo motor 208 drives the round rod 203 to rotate in the opposite direction, thereby wrapping the shielding cloth 210 around the outside of the round rod 203 through the rectangular hole 207.

[0032] A rectangular plate 206 is fixedly installed inside the groove 202. A rectangular hole 207 is opened on the surface of the rectangular plate 206, and the rectangular hole 207 corresponds to the shielding cloth 210.

[0033] The rectangular plate 206 limits the position of the shielding cloth 210, so that the shielding cloth 210 is evenly wrapped around the outside of the round rod 203 from the rectangular hole 207.

[0034] Among them, limit rings 204 are fixedly installed on the outer sides of both ends of the round rod 203, and arc grooves 205 are opened on the inner side of the limit rings 204.

[0035] The arc-shaped groove 205 assists in the storage of the covering cloth 210, allowing the covering cloth 210 to be evenly stored on the surface of the round rod 203.

[0036] Among them, a fixing block 214 is fixedly installed on the upper left end of the circulation pipe 15, and a long rod 217 extending to the inner side of the left end of the platform 201 is fixedly installed at the front end of the fixing block 214. The left end of the long plate 209 is movably sleeved on the outside of the long rod 217.

[0037] The long plate 209 is limited by the long rod 217, so that the long plate 209 can move downward along the vacuum tube 16 to release the shielding cloth 210.

[0038] Working principle and usage process of this utility model:

[0039] When it is necessary to shade the vacuum tube 16, the second servo motor 216 is started, which drives the screw 218 to rotate. The rotation of the screw 218 drives the long plate 209 to move downward along the long rod 217, so that the long plate 209 pulls the shading cloth 210 out from the inside of the platform 201. The round rod 203 rotates to release the shading cloth 210, so that the shading cloth 210 shades the vacuum tube 16. When it is necessary to retract, the second servo motor 216 drives the screw 218 to rotate in the opposite direction. At this time, the first servo motor 208 drives the round rod 203 to rotate in the opposite direction, so that the shading cloth 210 is wrapped around the outside of the round rod 203 through the rectangular hole 207. The arc groove 205 assists in the wrapping of the shading cloth 210.

[0040] When it is necessary to clean the vacuum tube 16, simply use water to clean the dust on the surface of the vacuum tube 16, and then start the servo motor 216 to make the long plate 209 move downward under the limit of the long rod 217, thereby driving the connecting plate 211 to move downward, and the connecting plate 211 to drive the cleaning ring 212 to move downward around the vacuum tube 16, thereby cleaning and wiping the surface of the vacuum tube 16 through the brush 213, effectively reducing the accumulation of dust.
