Description

Technical Field

[0001] This invention relates to the field of solar water heating equipment technology, specifically a solar water heating device combined with an irregularly shaped steel structure roof. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Steel structure roofs are usually equipped with solar water heating devices.

[0003] Most existing solar water heaters add cold water to the collector tubes and then heat the water in the tank through sunlight. However, the collector tubes in this type of solar water heater are prone to producing a lot of scale, which will affect the heat collection performance of the collector tubes over time. Each tube needs to be cleaned individually, which is quite troublesome. If the water is not used for a long time, such as when you are away on business or traveling, the water tank will be in a high temperature and high pressure state for a long time, which will accelerate the aging of the sealing ring. Excessive pressure can also cause the water tank to burst and build up a thick layer of scale, shortening the life of the water tank.

[0004] Combining the above issues, we find that existing solar water heaters on the market cannot simultaneously avoid the problems mentioned above when in use. Even if they can be solved, they require external tools to solve them, thus failing to achieve the desired effect. Therefore, we propose a solar water heating device that is combined with an irregularly shaped steel structure roof. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-10 The present invention provides a technical solution: a solar water heating device combined with an irregular steel structure roof. The present invention makes corresponding improvements to the technical problems mentioned in the background art, including a solar water heater body 1, the solar water heater body 1 including a support frame 11, a heat collection component 2 is provided on the top of the support frame 11, and a shell 12 is provided on one side of the heat collection component 2. The heat collection component 2 is used to heat water.

[0035] The heat collection assembly 2 includes a fixing plate 201 bolted to the top of the support frame 11. A placement groove 202 is provided on one side of the fixing plate 201. Several placement grooves 202 are provided, and a heat collection tube 203 is placed inside the groove. A support plate 204, which mates with the heat collection tube 203, is fixedly installed on one side of the fixing plate 201. Mounting holes 205, which mate with the heat collection tube 203, are provided on the surface of the outer shell 12. A sealing ring 206 is fixedly connected to the surface of the heat collection tube 203, and the surface of the sealing ring 206 is in close contact with the inner cavity of the mounting hole 205. A water storage shell 207, made of copper, is fixedly connected to the inner wall of the outer shell 12. The space between the water storage shell 207 and the outer shell 12, as well as the inner cavity of the heat collection tube 203, is filled with heat-conducting oil. By setting up the heat collection assembly 2, during installation… The collector tube 203 is placed in the inner cavity of the placement slot 202 and supported by the support plate 204. Then, the other end of the collector tube 203 is installed into the inner cavity of the mounting hole 205. The outer shell 12 and the collector tube 203 are sealed by the sealing ring 206. The space between the water storage shell 207 and the outer shell 12 and the inner cavity of the collector tube 203 are filled with heat-conducting oil. The inner cavity of the water storage shell 207 is filled with water. When sunlight shines, the heat-conducting oil in the collector tube 203 will be heated first, so that the heat-conducting oil between the water storage shell 207 and the outer shell 12 will be heated. The water storage shell 207 is made of copper to heat the water in the water storage shell 207. Adding heat-conducting oil to the collector tube 203 will prevent scale from forming in the collector tube 203 and reduce the cleaning steps of the collector tube 203.

[0036] Four fixed rods 208 are fixedly connected to the bottom of the support frame 11. One end of each fixed rod 208 is rotatably connected to a movable rod 209. One end of the movable rod 209 is slidably connected to a slide plate 210. A thin rod 211 is fixedly connected to the bottom of the slide plate 210. A thick rod 212 is slidably connected to the surface of the thin rod 211. A mounting plate 213 is fixedly connected to the bottom of the thick rod 212. A positioning rod 214 is slidably connected to the surface of the thick rod 212. Several positioning grooves 215 are formed on the surface of the thin rod 211. The surface of the positioning rod 214... The mounting plate 213 is threaded to the inner wall of the positioning groove 215. By using the fixed rod 208, movable rod 209, sliding plate 210, thin rod 211 and thick rod 212 in combination, the mounting plate 213 is installed on the irregular steel structure roof by bolt positioning during installation. When it is necessary to adjust the angle of the solar water heater body 1, the combination of adjusting the height of the thin rod 211 and sliding the movable rod 209 on the sliding plate 210 makes the solar water heater body 1 suitable for the irregular steel structure roof.

[0037] A vent pipe 216 is fixedly connected to one side of the water storage tank 207. One end of the vent pipe 216 extends to the outside of the outer shell 12. A drain pipe 217 is fixedly connected to the bottom of one side of the water storage tank 207. One end of the drain pipe 217 extends to the outside of the outer shell 12. By setting the vent pipe 216, when high temperature and high pressure are generated in the water storage tank 207, the pressure is released through the vent pipe 216. By setting the drain pipe 217, the hot water in the water storage tank 207 can be discharged for use.

[0038] The specific implementation of this embodiment is as follows: During installation, the mounting plate 213 is installed on the irregular steel structure roof using bolt positioning. When the angle of the support frame 11 needs to be adjusted, the height of the thin rod 211 is adjusted and the movable rod 209 slides on the sliding plate 210, thereby making the solar water heater body 1 suitable for the irregular steel structure roof. After the support frame 11 is installed, the heat collection tube 203 is placed in the inner cavity of the placement groove 202, and the heat collection tube 203 is supported by the support plate 204. Then, the other end of the heat collection tube 203 is installed into the inner cavity of the mounting hole 205, and the sealing ring 20 is used to seal it. The outer shell 12 and the heat collection tube 203 are sealed together. Then, the space between the water storage shell 207 and the outer shell 12 and the inner cavity of the heat collection tube 203 are filled with heat-conducting oil. The inner cavity of the water storage shell 207 is filled with water. When sunlight shines, the heat-conducting oil in the heat collection tube 203 will be heated first, so that the heat-conducting oil between the water storage shell 207 and the outer shell 12 will be heated. The water storage shell 207 is made of copper to heat the water in the water storage shell 207. Adding heat-conducting oil to the heat collection tube 203 will prevent scale from forming in the heat collection tube 203 and reduce the cleaning steps of the heat collection tube 203. The inner wall of the outer shell 12 is fixedly connected with an insulation layer.

[0039] Example 2

[0040] Please see Figure 1-10 The present invention provides a technical solution: a solar water heating device combined with an irregular steel structure roof. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The top of the support frame 11 is provided with an adjustment mechanism 3 for use with the heat collection component 2. The adjustment mechanism 3 includes a protection unit 31, which is used to protect the heat collection component 2 and increase the heat collection efficiency.

[0041] As a further definition of the adjustment mechanism 3 of the present invention, the protective unit 31 includes a connecting rod 3101 fixedly installed at the bottom of the support frame 11. A support rod 3102 is fixedly connected to the top of the connecting rod 3101. A sliding hole 3103 is opened on the surface of the support rod 3102. A sliding block 3104 is slidably connected to the inner cavity of the sliding hole 3103. Gears 3105 are rotatably connected to both sides of the sliding block 3104. A first tooth 3106 and a second tooth 3107 that cooperate with the gears 3105 are fixedly connected to the inner wall of the sliding hole 3103. The number of first teeth 3106 and second teeth 3107 are both several. On the opposite side, mounting plates 3108 are fixedly connected. A reflector 3109 is fixedly connected to one side of mounting plate 3108, and a shielding plate 3110 is fixedly connected to the other side of mounting plate 3108. A fixing tube 3111 is fixedly connected to the bottom of connecting rod 3101. A piston 3112 is slidably connected to the inner cavity of fixing tube 3111. An adjusting rod 3113 is fixedly connected to the top of piston 3112. One end of adjusting rod 3113 passes through fixing tube 3111, connecting rod 3101, and support rod 3102 in sequence and is fixedly connected to the bottom of sliding block 3104. The surface of adjusting rod 3113 is flush with the inner wall of fixing tube 3111. The inner wall of rod 3101 and the inner wall of support rod 3102 are slidably connected. A protective unit 31 is installed, and a temperature detection unit 32 detects the water temperature in the water storage tank 207. When the water temperature in the water storage tank 207 reaches the set temperature, piston 3112 moves upward, causing adjusting rod 3113 to move sliding block 3104. The movement of sliding block 3104 drives gear 3105 to move. When gear 3105 meshes with the first tooth 3106, gear 3105 drives mounting plate 3108 to rotate, causing baffle plate 3110 to block the top of heat collection tube 203, preventing heat collection tube 203 from being blocked. 3. Prolonged exposure to sunlight prevents the water storage tank 207 from being in a state of high temperature and high pressure for a long time. When the water temperature in the water storage tank 207 is lower than the set temperature, the sliding block 3104 will move downward, causing the gear 3105 to disengage from the first tooth 3106 and making the mounting plate 3108 in a vertical state. When the sliding block 3104 moves downward, the gear 3105 engages with the second tooth 3107, causing the mounting plate 3108 to rotate in the opposite direction, causing the reflector 3109 to reflect sunlight upward, thereby irradiating the bottom of the heat collection tube 203 and increasing the heat collection efficiency of the heat collection tube 203.

[0042] The inner wall of the sliding hole 3103 is provided with a guide groove 3114. A guide block 3115 is slidably connected to the inner cavity of the guide groove 3114. One side of the guide block 3115 is fixedly connected to one side of the sliding block 3104. By setting the guide block 3115 and the guide groove 3114 to work together, when the sliding block 3104 is moved, the guide block 3115 will be driven to move in the inner cavity of the guide groove 3114. The guide groove 3114 guides the guide block 3115 to prevent the sliding block 3104 from deviating when it moves.

[0043] A rotating rod 3116 is fixedly connected to one side of the gear 3105, and a locking block 3117 is fixedly connected to one end of the rotating rod 3116. The surfaces of the rotating rod 3116 and the locking block 3117 are rotatably connected to the inner cavity of the sliding block 3104. Two elastic ropes 3118 are fixedly connected to the surface of the rotating rod 3116, and one end of the elastic rope 3118 is fixedly connected to the inner wall of the sliding block 3104. By setting the rotating rod 3116, the locking block 3117 and the elastic ropes 3118 to work together, the rotation of the rotating rod 3116 will cause the elastic ropes 3118 to be stretched under force. At this time, the mounting plate 3108 is in a horizontal state. When the gear 3105 is disengaged from the first tooth 3106 or the second tooth 3107, the elastic ropes 3118 will contract, thereby causing the rotating rod 3116 to reset and the mounting plate 3108 to be in a vertical state.

[0044] The specific implementation of this embodiment is as follows: The temperature detection unit 32 detects the water temperature in the water storage tank 207. When the water temperature in the water storage tank 207 is lower than the set temperature, the piston 3112 moves upward, causing the adjusting rod 3113 to drive the sliding block 3104 to move. When the sliding block 3104 moves, it drives the guide block 3115 to move in the inner cavity of the guide groove 3114. The guide groove 3114 guides the guide block 3115 to prevent the sliding block 3104 from deviating during movement. When the gear 3105 meshes with the first tooth 3106, the gear 3105 drives the mounting plate 3108 to rotate, causing the baffle plate 3110 to... The top of the heat pipe 203 is shielded to prevent it from being exposed to sunlight for extended periods, thus preventing the water storage tank 207 from being under high temperature and pressure for a long time. When the water temperature in the water storage tank 207 reaches the set temperature, the sliding block 3104 moves downward, causing the gear 3105 to disengage from the first tooth 3106 and the mounting plate 3108 to be in a vertical position. When the sliding block 3104 moves downward, the gear 3105 engages with the second tooth 3107, causing the mounting plate 3108 to rotate in the opposite direction. This causes the reflector 3109 to reflect sunlight upward, thereby irradiating the bottom of the heat pipe 203 and increasing its heat collection efficiency.

[0045] Example 3

[0046] Please see Figure 1-10 The present invention provides a technical solution: a solar water heating device combined with an irregular steel structure roof. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The adjustment mechanism 3 also includes a temperature detection unit 32, which is used in conjunction with the protection unit 31. The temperature detection unit 32 is used to detect the temperature of the water.

[0047] As a further definition of the regulating mechanism 3 of the present invention, the temperature detection unit 32 includes a mounting shell 3201 fixedly installed on one side of the outer shell 12. A battery 3202, an inverter 3203, a controller 3204, and a negative pressure pump 3205 are fixedly installed inside the mounting shell 3201. A temperature sensor 3206 is fixedly connected to the inner wall of the water storage shell 207. A solar panel 3207 is fixedly connected to the top of the mounting shell 3201. The solar panel 3207 is electrically connected to the inverter 3203, and the inverter 3203 is electrically connected to the battery 3202. The temperature sensor 3206 and the negative pressure pump 3205 are both electrically connected to the controller 3204. The temperature sensor 3206, the negative pressure pump 3205, and the controller 3204 are all powered by the battery 3202. A connecting pipe 3208 is fixedly connected to the outlet end of the negative pressure pump 3205. One end of 08 is fixedly connected to an air intake pipe 3209, and one end of several fixed pipes 3111 is fixedly connected to the surface of the air intake pipe 3209. By setting a temperature detection unit 32, the temperature sensor 3206 detects the temperature of the water in the water storage tank 207. When the water temperature in the water storage tank 207 reaches the set temperature, the temperature sensor 3206 will transmit a signal to the controller 3204, thereby starting the negative pressure pump 3205, allowing air to enter the connecting pipe 3208, causing the gas to exert pressure on the piston 3112 and push the piston 3112, thereby causing the piston 3112 to drive the adjusting rod 3113 to move upward. When the water temperature in the water storage tank 207 is lower than the set temperature, the negative pressure pump 3205 will suck away the air, forming a negative pressure, thereby causing the piston 3112 to move in the opposite direction, causing the reflector 3109 to reflect sunlight.

[0048] Preferably, a sealing plate 3210 is movably connected to one side of the mounting housing 3201. A threaded rod 3211 is provided on one side of the sealing plate 3210. One end of the threaded rod 3211 passes through the sealing plate 3210 and is threadedly connected to the inner cavity of the mounting housing 3201. The surface of the threaded rod 3211 is slidably connected to the inner cavity of the sealing plate 3210. By setting the sealing plate 3210 and the threaded rod 3211 in cooperation, when the negative pressure pump 3205, the battery 3202 and the controller 3204 are damaged, the sealing plate 3210 can be disassembled, so that the negative pressure pump 3205, the battery 3202 and the controller 3204 can be replaced.

[0049] A pressure relief valve 3212 is fixedly connected to the top of the outer casing 12, and a drain valve 3213 is fixedly connected to the bottom of the outer casing 12. By setting the pressure relief valve 3212, the air pressure between the outer casing 12 and the water storage tank 207 can be discharged. By setting the drain valve 3213, the heat transfer oil between the outer casing 12 and the water storage tank 207 can be discharged.

[0050] The specific implementation of this embodiment is as follows: The temperature sensor 3206 detects the temperature of the water in the water storage tank 207. When the water temperature in the water storage tank 207 reaches the set temperature, the temperature sensor 3206 transmits a signal to the controller 3204, thereby activating the negative pressure pump 3205. This allows air to enter the connecting pipe 3208, causing the gas to exert pressure on the piston 3112 and push it. When the water temperature in the water storage tank 207 is lower than the set temperature, the negative pressure pump 3205 draws away the air, creating a negative pressure. This causes the piston 3112 to move in the opposite direction, allowing the reflector 3109 to reflect sunlight. The solar panel 3207 and the inverter 3203 store electricity in the battery 3202, so that the temperature sensor 3206, the negative pressure pump 3205, and the controller 3204 are all powered by the battery 3202.

[0051] The working principle of this invention is as follows: The mounting plate 213 is installed on the irregular steel structure roof by bolt positioning. When the angle of the support frame 11 needs to be adjusted, the height of the thin rod 211 is adjusted and the movable rod 209 slides on the sliding plate 210, so that the solar water heater body 1 can be adapted to the irregular steel structure roof. After the support frame 11 is installed, the heat collection tube 203 is placed in the inner cavity of the placement groove 202 and supported by the support plate 204. Then, the other end of the heat collection tube 203 is installed into the inner cavity of the mounting hole 205. The sealing ring 206 seals the space between the outer shell 12 and the heat collection tube 203. Then, the water storage shell 207 is sealed with the outer shell 12 and the heat collection tube 203. The inner cavity of the 03 is filled with heat-conducting oil, while the inner cavity of the water storage shell 207 is filled with water. When sunlight shines, it preferentially heats the heat-conducting oil in the heat collector tube 203, causing the heat-conducting oil between the water storage shell 207 and the outer shell 12 to heat up. The water storage shell 207 is made of copper to heat the water inside. Adding heat-conducting oil to the heat collector tube 203 prevents scale buildup, reducing the need for cleaning. During use, the temperature sensor 3206 detects the water temperature in the water storage shell 207. When the water temperature in the water storage shell 207 reaches the set temperature, the temperature sensor 3206 sends a signal to the controller 3204, thereby creating a negative pressure. Pump 3205 starts, allowing air to enter connecting pipe 3208. This gas pressures piston 3112, pushing it forward and causing adjusting rod 3113 to move sliding block 3104. As sliding block 3104 moves, it moves guide block 3115 within guide groove 3114, guiding it and preventing sliding block 3104 from shifting. When gear 3105 meshes with first tooth 3106, it rotates mounting plate 3108, causing shielding plate 3110 to shield the top of collector tube 203 from prolonged sunlight exposure. To prevent prolonged exposure to direct sunlight, the water storage tank 207 is kept under high temperature and pressure. When the water temperature inside the water storage tank 207 is lower than the set temperature, the negative pressure pump 3205 will draw away the air, creating negative pressure. This causes the piston 3112 to move in the opposite direction, and the sliding block 3104 to move downward. This causes the gear 3105 to disengage from the first tooth 3106, and the mounting plate 3108 to be in a vertical position. When the sliding block 3104 moves downward, the gear 3105 engages with the second tooth 3107, causing the mounting plate 3108 to rotate in the opposite direction. This causes the reflector 3109 to reflect sunlight upward, thereby irradiating the bottom of the heat collection tube 203 and increasing the heat collection efficiency of the heat collection tube 203.
