The utility model discloses a full-automatic non-automatically controlled rolls up curtain up-and-down motion according to the heat collector temperature and reaches and cover heat collector purpose device.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a self-balancing formula is prevented empty and is shone stifled solar collector that shines, has many thermal-arrest person in charge, its characterized in that:
the temperature sensing component is arranged on one side of the heat collection main pipe and can measure the temperature of the heat collection main pipe, the temperature sensing component is a closed container with a phase change medium inside, the closed container is communicated with a pneumatic cylinder through a capillary channel, and a piston rod of the pneumatic cylinder can drive a scroll of the roller shutter to rotate, so that the amount of the area of the roller shutter, which faces the sun, for shielding the heat collection main pipe is controlled.
The self-balancing solar collector capable of preventing empty sunning and closed sunning is characterized in that: the piston rod of pneumatic cylinder and a driving chain fixed connection, the driving chain is around between a rotating gear and a limiting gear, relies on the driving chain drives rotating gear and takes place the rotation, rotating gear drives again the spool synchronous revolution.
The self-balancing solar collector capable of preventing empty sunning and closed sunning is characterized in that: the roller shutter moves on the sunny side of the heat collection main pipe along the guide rail.
The self-balancing solar collector capable of preventing empty sunning and closed sunning is characterized in that: the piston rod of pneumatic cylinder and a rack fixed connection, the rack meshes with a rotating gear and is connected, rotating gear can drive the spool synchronous revolution.
The utility model has the advantages that judge the change of heat collector pipe temperature through the temperature sensing part, in case the temperature has reached established temperature, the atmospheric pressure transmission that the temperature sensing part produced gives the pneumatic cylinder, and the pneumatic cylinder drives the driving chain, then the curtain roller bearing is rolled up in the driving chain drive rotates, receive and releases to rolling up the curtain to reach the purpose of hiding and releasing collecting area, thereby reach control heat collector temperature, in order to reach the purpose of protection heat collector and heat collecting system.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications can be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the present application.
As shown in fig. 1 and fig. 2, the self-balancing solar collector 1 for preventing empty sunning and stuffy sunning provided by the utility model is provided with a plurality of heat collecting main pipes 2;
in order to prevent the heat collection main pipe 2 from being damaged under the long-time idle sunning condition, a temperature sensing component 3 is arranged on one side of the heat collection main pipe 2, as shown in fig. 3, the temperature sensing component 3 is a closed container with a phase change medium inside, the closed container is communicated with a pneumatic cylinder 4 through a capillary channel, a piston rod of the pneumatic cylinder 4 is fixedly connected with a transmission chain 6, the transmission chain 6 is wound between a rotating gear 7 and a limiting gear 5, the transmission chain 6 is used for driving the rotating gear 7 to rotate, and the rotating gear 7 further drives a reel of a roller shutter 8 to rotate, so that the roller shutter 8 is controlled to move along a guide rail 9, and part or all of the exposed area of the heat collection main pipe 2 is shielded.
The utility model discloses the theory of use as follows:
A. when the heat collector is installed at the initial stage or a user does not use a hot water system for a long time, the temperature of the solar heat collector 1 is high, when the temperature of the heat collection main pipe 2 reaches the boiling point of a liquid phase change medium in the temperature sensing part 3, the phase change medium in the temperature sensing part 3 is converted into gas, the gas enters the air inlet cavity of the pneumatic cylinder 4 through the capillary channel of the temperature sensing part 3, the friction resistance between the atmospheric pressure and the inner wall of the piston rod and the inner wall of the pneumatic cylinder 4 is overcome through the gas pressure, the piston rod in the pneumatic cylinder 4 drives the transmission chain 6 fixed at the top end of the piston rod to move upwards, the rotating gear 7 is driven to rotate under the action of the limiting gear 5 and acts on the scroll in the middle of the roller shutter 8, the scroll drives the roller shutter 8 to cover the heat collection main pipe 2, the roller shutter 8 moves up and, thereby realizing the function of preventing the heat collector from being sunned in the air and being closed.
B. After the heat collector temperature reduces at night or in continuous overcast and rainy days, the heat collection is responsible for 2 temperature reductions, the gaseous state medium liquefaction in the chamber of admitting air of pneumatic cylinder 4 this moment flows into temperature sensing part 3, the chamber pressure drop of admitting air in pneumatic cylinder 4 this moment, drive chain 6 downstream under the action of gravity of atmospheric pressure and piston rod, under stop gear 5's effect, drive rotating gear 7 and rotate, and act on the spool in the middle of rolling up curtain 8, the spool drives rolling up curtain 8 along guide rail 9 upward movement, release heat collector area to the sun, so that carry out heat collection.
