[0002] Electric boilers are also called electric heating boilers or electric heating boilers. They use electricity as energy and convert it into heat energy, which is then converted by the boiler to output steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The electric boiler body is mainly composed of a steel shell, a computer control system, a low-voltage electrical system, an electric heating pipe, an inlet and outlet water pipe, and detection instruments.

A solar electric boiler hybrid heating device, after the staff stirs the water body with the stirring assembly, further detects the temperature of the water body through a temperature detection probe, the temperature detection probe is connected to the controller inside the control cabinet, when the temperature inside the boiler body reaches the set temperature, the temperature detection probe transmits a signal to the controller inside the control cabinet, and the controller stops heating the water inside the boiler body, preventing the water body from overheating and producing steam to cause waste, and the method of preventing the water body from overheating is simple and efficient.

[0040] Support plates 21 for supporting the preheating unit 4 are symmetrically arranged on both sides of the top surface of the support base 2. The preheating unit 4 includes a concave mirror 40 located directly below the furnace body 1, a heat storage bulb 431 arranged at the focusing point of the concave mirror 40, a water supply pipe 42 for supplying water to the heat storage bulb 431, and a preheating pipe 43 for connecting the furnace body 1 and the heat storage bulb 431.

[0041] An adjusting portion 3 for adjusting the swing angle of the concave mirror 40 is arranged above the support seat 2; the adjusting portion 3 includes a semicircular slide rail 30 rotatably connected between the two support plates 21, two symmetrically arranged sliding mechanisms 301 slidably connected to the semicircular slide rail 30, a bent rack 32 arranged in the middle of the semicircular slide rail 30, and a longitudinal driving mechanism 33 fixedly arranged on the top surface of the support seat 2 for driving the semicircular slide rail 30 to rotate; the rotation center of the semicircular slide rail 30 is located at the location of the heat storage bulb 431, and the swing center of the sliding mechanism 301 is located at the location of the heat storage bulb 431, thereby ensuring that the sunlight energy concentrated at the focus of the concave mirror 40 always heats the heat storage bulb 431.

[0042] Preferably, a water storage tank 20 for storing water is provided at the center of the top surface of the support seat 2, a drain outlet 201 is provided on one side of the support seat 2, and the water storage tank 20 is connected to the drain outlet 201; at least three support rods 22 for supporting the furnace body 1 are installed in a circular shape near the edge at equal intervals by bolts, and the support rods 22 include a vertical section in the lower section and an inclined section in the upper section.

[0043] Specifically, rotating columns 31 are vertically embedded on the outer sides of both ends of the semicircular slide rail 30, and the two rotating columns 31 are symmetrically arranged and on the same straight line. The curved rack 32 is fixedly connected to the semicircular slide rail 30 by bolts and crosses each other vertically. A strip hole for drainage is opened in the middle of the curved rack 32; the longitudinal driving mechanism 33 includes a support block 330 and a support plate 331 fixed to one side of the top surface of the support seat 2 by bolts, and a gear 332 is rotatably connected between the support block 330 and the support plate 331, and the gear 332 is meshed with the curved rack 32. A second servo motor 333 is installed on the support block 330 by bolts, and the output shaft of the second servo motor 333 is coaxially connected with the gear 332, so that the semicircular slide rail 30 can drive the concave mirror 40 to rotate along the rotating column 31.

[0044] Furthermore, the sliding mechanism 301 includes a support leg 3011 fixedly connected to the convex surface of the concave mirror 40 by bolts, and two silicone rollers 3012 are rotatably connected between the bottom of the support leg 3011. The two silicone rollers 3012 on the same side are clamped on the outer sides of the upper and lower arc surfaces of the semicircular slide rail 30, so that the concave mirror 40 can stably slide along the semicircular slide rail 30; a first servo motor 3013 is installed on the outer wall of one of the support legs 3011 by bolts, and the output shaft of the first servo motor 3013 is coaxially connected to one of the silicone rollers 3012.

[0045] Preferably, the concave mirror 40 includes a center ring 401, and a plurality of frames 402 are welded radially outward from the center ring 401. All frames 402 are arranged at equal intervals and their number corresponds one-to-one with the number of support rods 22. A lens 403 is fixedly installed between every two adjacent frames 402 by bolts for easy transportation and assembly, and the concave surface of the lens 403 adopts a metal coating with high reflectivity, such as silicon metal.

[0046] Specifically, a fixing ring 220 capable of fixing and allowing the water supply pipe 42 to pass through is welded to the bottom end of the inclined section of one of the support rods 22, and the vertical section of the support rod 22 and the vertical section of the water supply pipe 42 are attached to each other and fixed by bolts.

[0047] Specifically, a first one-way valve 420 is installed at the bottom end of the hook of the water supply pipe 42, and a second one-way valve 430 is installed on the preheating pipe 43. The second one-way valve 430 is located above the heat storage bulb 431. The flow direction of the first one-way valve 420 is obliquely downward, and the flow direction of the second one-way valve 430 is vertically upward. The first one-way valve 420 allows the water from the water pump 41 to enter the spiral tube 44 in the heat storage bulb 431 and be preheated without flowing back into the water supply pipe 42 to cause heat loss. When the water pump 41 is not working, the water retained in the spiral tube 44 is heated by the solar energy reflected by the concave mirror 40 to overheat and expand, and can automatically open the second one-way valve 430 to enter the upper section of the preheating tube 43 and enter the furnace body 1, thereby eliminating the risk of explosion due to continuous heat storage at the spiral tube 44.

[0048] Specifically, a spiral tube 44 is provided in the heat storage bulb 431, which is connected from top to bottom. The spiral tube 44 is spread out in a spherical shape and is evenly close to the inner wall of the heat storage bulb 431, thereby increasing the heat conduction area and heat conduction time of the water pipe so that the heat absorbed by the heat storage bulb 431 can be fully heated.

[0049] Specifically, between the inner wall of the heat storage bulb 431 and the spiral tube 44 is a heat conduction cavity 440 filled with a heat conduction material to increase the heat conduction efficiency. The heat conduction material is metal particles or graphene. A transparent vacuum cover 432 capable of locking heat is installed on the outer sides of the upper and lower ends of the heat storage bulb 431 by bolts. The transparent vacuum cover 432 is spherical in shape and its inner diameter is larger than the outer diameter of the heat storage bulb 431. There is a vacuum state between the outer wall of the heat storage bulb 431 and the inner wall of the transparent vacuum cover 432, so that after the heat storage bulb 431 absorbs the heat from the concave mirror 40, it is difficult for the heat storage bulb 431 to escape from the outer wall of the heat storage bulb 431.

[0050] Preferably, a cleaning mechanism 45 capable of rotating and washing the concave mirror 40 is threadedly installed at the bottom end of the preheating tube 43, and the cleaning mechanism 45 includes an electric on-off valve 450 capable of controlling the opening or closing of the cleaning mechanism 45, and the lower end of the electric on-off valve 450 is rotatably connected and communicated with a rotating spray head 451, and the rotating spray head 451 is cylindrical in shape, and the circular top surface of the rotating spray head 451 is evenly spaced and provided with at least four rotationally symmetrical water inlet grooves 4510, and the water inlet grooves 4510 are arranged on the rotating spray head 4 The arc surface of 51 is connected with a spray pipe 4511, the water inlet groove 4510 is long and is on the same straight line with the corresponding spray pipe 4511, and each spray pipe 4511 is tangent to the outer side surface of the corresponding rotating spray head 451; when the electric on-off valve 450 is opened to allow water to enter the water inlet groove 4510 of the rotating spray head 451, the water flow is ejected from the spray pipe 4511 and the spray force acts on the tangent to make the rotating spray head 451 rotate and spray water to clean the concave mirror 40.

[0051] Finally, it should be noted that the furnace body 1, the first servo motor 3013, the second servo motor 333, the water pump 41, the first one-way valve 420, the second one-way valve 430, the electric on-off valve 450 and the controller involved in the present invention are all universal standard parts or parts known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the art.

[0052] Working principle:

[0053] The controller needs to be connected to the Internet to calculate whether it is worth adjusting the angle of the concave mirror 40 on that day (because adjusting the angle also consumes electricity) by comparing the real-time information such as the weather and the solar incident angle of the day. If it is not worth adjusting, it will remain unchanged; if it is worth adjusting, the first servo motor 3013 is started to drive one of the silicone rollers 3012, and drive the concave mirror 40 to slide along the semicircular slide 30 to a suitable position; at the same time, the second servo motor 333 is started to drive the gear 332 to rotate and transmit the curved rack 32, so that the semicircular slide 30 rotates along the rotating column 31 to adjust to a suitable angle. The angle changes in the two perpendicular directions enable the concave mirror 40 to dynamically align with the sun's position, so that the heat storage bulb 431 is continuously at the focus of the concave mirror 40 with the strongest solar incident angle;

[0054] The sunlight is reflected by the concave mirror 40 and enters the transparent vacuum cover 432 and enters the heat storage bulb 431. However, it is difficult for the heat to escape from the transparent vacuum cover 432 through the vacuum between the transparent vacuum cover 432 and the heat storage bulb 431. At this time, the light heats up the heat storage bulb 431, and the heat is then transferred to the spiral tube 44 through the heat-conducting material in the heat-conducting cavity 440 and heats the water in the spiral tube 44. When the water pump 41 does not work and the water in the spiral tube 44 expands due to heating or gravity and wants to flow back into the water supply pipe to cause heat loss, the first one-way valve 420 is closed to prevent the water from flowing back to the water pump 41. When the water in the spiral tube 44 expands due to the sunlight reflected by the concave mirror 40, the second one-way valve 430 is opened to allow the expanded hot water to enter the upper section of the preheating tube 43 and enter the furnace body 1.

[0055] When it is necessary to clean the surface of the concave mirror 40 to maintain the reflectivity of the concave mirror 40, while the water pump 41 is pumping water, the electric on-off valve 450 is powered on and opened to allow water to enter the rotating spray head 451. After the water enters the water inlet tank 4510 of the rotating spray head 451, the water flow is ejected from the injection pipe 4511 and the injection force acts on the tangent to make the rotating spray head 451 rotate and spray water to clean the concave mirror 40. Finally, the sewage flows down through the center circle 401 into the water storage tank 20 and is discharged from the drain outlet 201.

[0056] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
