The overheating prevention device comprises a roller case; a roller is arranged in the roller case, a transmission motor is arranged on the inner wall of the roller case and in transmission connection with the inner wall of the roller case, the roller is connected fixedly with the output shaft of the transmission motor, a shading plate is wound on the roller; slide ways are distributed at both ends of the roller case, both ends of the shading plate are embedded in the slide ways, the shading plate can be slid relative to the slide way, and the roller can be rotated relative to the roller case. The utility model has the advantages of simple structure, convenient mounting and use, and stable performance; the shading plate is spread to shade a glass vacuum heat collecting pipe in order to prevent the glass vacuum heat collecting pipe from continuously absorbing the radiant heat of solar energy, thereby the solar water heater is prevented from being overheated and the service life of the solar water heater is prolonged.
Description
Technical field
The utility model relates to a kind of over-temperature protection, and especially a kind of reel sliding rail type solar energy superheating prevention device belongs to the technical field of solar water heater servicing unit.
Background technology
At present, along with the development of China's economic level and the raising of people's living standard, because of solar water heater (hot-water heating system) has advantages such as energy-saving and environmental protection, safety, convenience, solar energy utilization ratio is more and more higher, increasing family begins to install and use solar product, and solar product is become and colour TV, refrigerator, household necessary article that washing machine is the same.This year, world climate and environment conference were held in Copenhagen, and the people of the world is paying close attention to the variation of climatic environment, and each country is all in the utilization of putting into effect relevant policy encouragement solar energy successively.But in use also can there be a problem in solar energy, summer superheating phenomenon.Solar energy resources is different with general conventional energy resource, the four seasons distribute very uneven, winter deficiency, spring and autumn can meet the demands substantially, residue appears summer, especially when have a summer holiday summers such as some schools, hot water in the solar water heater is in dead status, but solar water heater still can continue the water in the water tank is heated, cause in the solar water heater water tank temperature of hot water more and more higher, situations such as high-temperature evaporation will appear, influence system stability, reduce system's solar collecting performance, even hot water or high-temperature steam scald accident can occur spraying, also can occur the phenomenon of water tank blast when blocked or safety valve is malfunctioning when exhaust outlet, influence the safe in utilization of solar water heater.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reel sliding rail type solar energy superheating prevention device is provided, its easy to install, stable and reliable for performance and long service life.
According to the technical scheme that the utility model provides, described reel sliding rail type solar energy water heater over-temperature protection comprises the spool case; Be provided with spool in the described spool case, the inwall of spool case is provided with fixedly connected driving motor, and spool is fixedlyed connected with the output shaft of driving motor, is wound with anti-dazzling screen on the described spool; The two ends of described spool case are distributed with rail plate, and the two ends of described anti-dazzling screen are embedded in the rail plate, and anti-dazzling screen slides in the rail plate relatively, and described spool can rotate by the relative volume axle box.
Described rail plate is provided with fixedly connected connection support.
Advantage of the present utility model: simple in structure, easy to install, stable performance, by the expansion of anti-dazzling screen, block the radiations heat energy that glass heat-collecting vacuum tube absorbs solar energy, can avoid the solar energy problems of excessive heat, prolong the service life of solar water heater.
Description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is the connection diagram of the utility model driving motor and spool.
Fig. 3 is the utility model anti-dazzling screen deployed condition schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 3: the utility model comprises driving motor 1, spool 2, spool case 3, connects support 4, rail plate 5 and anti-dazzling screen 6.
As depicted in figs. 1 and 2: described driving motor 1 all is positioned at spool case 3 with spool 2, driving motor 1 is fixedlyed connected with the inwall of spool case 3, spool 2 is fixedlyed connected with the output shaft of driving motor 1, and the output shaft of driving motor 1 rotates and drives 3 rotations of spool 2 relative volume axle boxes.The two ends of described spool case 3 are provided with rail plate 5, and rail plate 5 is corresponding with the glass heat-collecting vacuum tube length of solar water heater.Be provided with the anti-dazzling screen 6 that is slidingly matched in the described rail plate 5, an end of anti-dazzling screen 6 is wrapped on the spool 2.Described anti-dazzling screen 6 can be along with the rotation of spool 2, be wrapped on the spool 2 or slip expansion in rail plate 5, thereby block solar water heater upper glass vacuum heat collection pipe and absorb the solar radiation heat, avoided under the condition of high temperature, glass heat-collecting vacuum tube continues to absorb solar energy and causes the overheated of solar energy.Described rail plate 5 is provided with fixedly connected connection support 4, and rail plate 5 utilizes connection support 4 to fixedly connected with the support of solar water heater, makes whole over-temperature protection be fixed on the glass heat-collecting vacuum tube top.
As Fig. 1～shown in Figure 3: during use, utilize to connect support 4 and fixedlys connected, spool case 3 and rail plate 5 are fixed on above the glass heat-collecting vacuum tube with the support of solar water heater.When temperature higher, when glass heat-collecting vacuum tube continues to absorb heat, by starting driving motor 1, the output shaft drive spool 2 of driving motor 1 is rotated in spool case 3, the anti-dazzling screen 6 that twines on the spool 2 can slide by relative rail plate 5, thereby block corresponding to glass heat-collecting vacuum tube, stop the heat absorption of glass heat-collecting vacuum tube, avoided the overheated of water heater.When needs utilize glass heat-collecting vacuum tube absorption heat that the water in the solar water heater is heated, start driving motor 1 once more, anti-dazzling screen 6 is wrapped on the spool 2, exposed glass heat-collecting vacuum tube, thus realization is to the heating of cold water in the solar water heater.By anti-dazzling screen 6 is set, avoided the overheated of solar water heater, whole over-temperature protection, simple in structure, safe and reliable, can prolong service life of solar water heater.
