Description

Technical Field

[0001] The invention relates to the technical field of solar energy collectors, and in particular to a building roof integrated flat-plate solar energy collector. Background Art

[0002] Flat-plate solar water heaters are designed and developed for small high-rise residential buildings. The water tank is placed on the balcony, roof, wall and other places. The flat-plate solar collector is placed on the balcony, window, roof and wall of the south facade of the building, which makes up for the regret that traditional solar water heaters cannot be integrated with the building and the environment due to their inherent deficiencies. The collector and the water tank are separated from each other. The collector can be flexibly installed on the roof, skylight, balcony or wall without being restricted by the location, achieving an integrated combination with the high-rise building and the environment.

[0003] According to the publicized building roof integrated flat plate solar collector (publication number: CN 2876224Y), it includes several flat plate solar collectors, which are characterized in that it also includes an outer frame, the flat plate solar collector is placed in the outer frame, and there are positioning guide rail convex pieces of the flat plate solar collector on the inner side of the outer frame, so that the flat plate solar collector can be installed flat in the outer frame; the gaps between adjacent flat plate solar collectors and between the flat plate solar collector and the outer frame are equipped with waterproof panels, which are inserted into the square grooves of the flat plate solar collector frame. It has the advantages of good combination performance with the building body, high safety performance, simple installation, conducive to the planning of the roof of the building complex, beautification of the city appearance, and solving the harmonious unity of the city appearance and environment, environment and environmental protection.

[0004] However, the outer frame, positioning guide rail protrusions, waterproof panels and other internal components in the above application cooperate with each other, making it difficult to realize the automatic cleaning of the surface solar panel of the integrated flat-plate solar collector on the building roof. Therefore, we propose an integrated flat-plate solar collector on the building roof. Summary of the invention

[0005] The present invention provides a building roof integrated flat-plate solar thermal collector, which solves the problem in the prior art that it is difficult to automatically clean the surface solar composite panels of the building roof integrated flat-plate solar thermal collector.

[0006] The technical solution of the present invention is as follows: The present invention is a flat-plate solar collector integrated with a building roof, comprising a solar collector; a fixing plate is fixedly connected to the side of the solar collector, and a cleaning water outlet device is arranged on the side of the fixing plate; Furthermore, the cleaning water outlet device includes a three-phase asynchronous motor, the bottom of the three-phase asynchronous motor is fixedly connected to the side of the fixed plate, the output shaft of the three-phase asynchronous motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a threaded sleeve, the side of the threaded sleeve is fixedly connected to an impact rod, the side of the fixed plate is fixedly connected to a limiting rod, the cleaning water outlet device includes a water pump box, the side of the water pump box is slidably connected to a force rod through an internal piston, a one-way valve is arranged on the side of the water pump box, a water inlet is opened at the bottom of the water pump box, the side of the water inlet is rotatably connected to a rotating shaft, the side of the rotating shaft is fixedly connected to a closing plate, and the side of the one-way valve is fixedly connected to a spray head. Such a design can clean the water outlet device to automatically discharge water to clean the surface of the solar panel of the integrated flat-plate solar collector on the building roof, so that the integrated flat-plate solar collector on the building roof can maintain better heating, improve work efficiency, and reduce labor. Through the cooperation of the driving force of the motor, the threaded rod, the threaded sleeve, the water pump box and other components, the rotation of the threaded rod drives the threaded sleeve to perform reciprocating horizontal motion under the restriction of the limit rod, and the reciprocating horizontal motion of the threaded sleeve drives the impact rod to impact the force-bearing rod, so that the one-way valve on the water pump box discharges water through the nozzle, thereby allowing the equipment to clean the surface of the integrated flat-plate solar collector on the building roof.

[0007] Furthermore, the above-mentioned integrated flat-plate solar collector for building roof is characterized in that a reset torsion spring is fixedly connected to the circumferential surface of the stress-bearing rod, one end of which is fixedly connected to the water pump box, and a reset tension torsion spring is fixedly connected to the side of the rotating shaft, one end of which is fixedly connected to the water inlet. With such a design, when the impact rod hits the stress-bearing rod, the stress-bearing rod can be reset by the tension of the reset torsion spring, achieving the effect of repeated impact and forming automation.

[0008] Furthermore, the side of the threaded sleeve is slidably connected to the side of the limiting rod, and the threaded rod is consistent with the limiting rod in length. With such a design, the threaded sleeve can perform reciprocating horizontal motion under the limiting effect of the limiting rod.

[0009] Furthermore, the material of the nozzle is set to be metal, and the diameter of the nozzle is the same as the diameter of the solar collector. Such a design is based on the consideration that the building roof integrated flat-plate solar collector is exposed for a long time, and the use of metal material can prevent the nozzle from being damaged.

[0010] Furthermore, a water removal and sewage collection device is provided on the side of the solar collector, an internal threaded sleeve is threadedly connected on the circumferential surface of the threaded rod, a support rod is fixedly connected on the circumferential surface of the internal threaded sleeve, a water removal plate is fixedly connected on the side of the support rod, and a water collection tank is fixedly connected on the side of the solar collector. Such a design can collect sewage on the cleaned solar collector, so that the solar collector can maintain a clean surface. Through the mutual cooperation of the threaded rod, the internal threaded sleeve, the water removal plate, the sewage collection tank and other components, the threaded rod rotates to drive the threaded sleeve to perform reciprocating horizontal motion under the restriction of the limit rod, and the reciprocating horizontal motion of the threaded sleeve drives the water removal plate to perform reciprocating horizontal motion, pushing the sewage into the water collection tank and flowing into the sewage collection tank, thereby collecting the sewage left on the surface of the roof-integrated flat-plate solar collector after cleaning.

[0011] Furthermore, a drainage lower arc plate is fixedly connected to the inner side of the water collecting tank, and the diameter of the water removal plate is consistent with the diameter of the solar collector. Such a design is that when water flows into the water collecting tank, it is more fully drained into the sewage collection tank under the action of the drainage lower arc plate.

[0012] Furthermore, a sewage collection box is fixedly connected to the side of the water collection tank, and the volume of the sewage collection box is consistent with the volume of the water pump box. Such a design is that when water flows into the water collection tank, it is more fully drained into the sewage collection box under the action of the drainage lower arc plate.

[0013] Furthermore, the material of the dewatering plate is set to be a soft colloid, and the top of the water collecting tank is located on the displacement track of the dewatering plate. Such a design prevents the dewatering plate from being too hard and causing damage to the solar panel.

[0014] Further, a solar panel protection device is provided on the top of the water pump box, and the solar panel protection device includes a second fixing plate, the second fixing plate is fixedly connected to the top of the water pump box, the side of the second fixing plate is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a second threaded rod, the side of the second fixing plate is fixedly connected to a second threaded rod, the side of the second fixing plate is fixedly connected to a second limit rod, the circumferential surface of the second threaded rod is threadedly connected to a second threaded sleeve, the side of the second threaded sleeve is fixedly connected to an extension rod, the bottom of the extension rod is fixedly connected to a shielding cloth, the circumferential surface of the second threaded rod is fixedly connected to a fixed sleeve, and one end of the shielding cloth is fixedly connected to the bottom of the fixed sleeve. Such a design can protect the solar panel through the solar panel protection device in bad weather to prevent the solar panel from being damaged. Through the cooperation of the second threaded rod, the second threaded sleeve and other components, the second threaded rod rotates to drive the second threaded sleeve to move horizontally under the restriction of the second limit rod, and the horizontal movement of the second threaded sleeve drives the shielding cloth to move horizontally, so as to cover and protect the solar panel, thereby protecting the solar panel.

[0015] Furthermore, the second threaded sleeve is slidably connected to the second limiting rod, and the length of the shielding cloth is consistent with the length of the solar thermal collector. Such a design drives the shielding cloth to protect the solar panel through the second threaded sleeve.

[0016] The present invention provides a flat-plate solar collector integrated with a building roof. It has the following beneficial effects: 1. The present invention realizes that the rotation of the threaded rod drives the threaded sleeve to perform reciprocating horizontal motion under the restriction of the limit rod through the cooperation of the driving force of the motor, the threaded rod, the threaded sleeve, the water pump box and other components. The reciprocating horizontal motion of the threaded sleeve drives the impact rod to impact the force-bearing rod, so that the one-way valve on the water pump box discharges water through the nozzle, thereby enabling the equipment to clean the surface of the integrated flat-plate solar collector on the building roof.

[0017] 2. The present invention realizes that the threaded rod rotates to drive the threaded sleeve to perform reciprocating horizontal motion under the restriction of the limit rod through the mutual cooperation of components such as the threaded rod, the internal threaded sleeve, the water removal plate, and the sewage is pushed into the water collection tank and flows into the sewage collection box, thereby realizing the collection of sewage remaining on the surface of the roof-integrated flat-plate solar collector after cleaning.

[0018] 3. The present invention realizes that the second threaded rod rotates and drives the second threaded sleeve to move horizontally under the restriction of the second limit rod through the cooperation of the second threaded rod, the horizontal movement of the second threaded sleeve drives the shielding cloth to move horizontally, and the solar panel is covered and protected, thereby protecting the solar panel.
