[0004] The current curved collector encounters snow weather, and the fixed snow is easily attached to the surface of the reflecting plate; without manual active cleaning in a short time, the snow accumulated on the reflecting plate does not immediately melt due to the cold weather, but is always attached to the surface of the reflecting plate; when the weather is slightly hot, part of the snow will melt away, and the melted snow will be attached to the lower layer of snow, which will make the snow hard; at this time, manual snow removal will become difficult; as shown in the figure, the surface area of the reflecting plate is large, and the snow basically will not fall off without manual cleaning, which leads to the light reflection effect of the reflecting plate; in order to maximize the heat collection effect of the collector, the surface area of the curved collector is greatly increased, which also greatly increases the difficulty of cleaning the reflecting plate.

[0049] When working, the heating temperature of the heating plate 94 cannot be higher than 100 degrees, so that the elastic sealing rubber 10 can be avoided from being cracked or deformed due to high temperature, and the sealing effect and the normal snow removing work are affected.

[0050] As an embodiment of the present application, as shown in Figures 1 to 5 When the snow on the upper end of the reflecting plate 7 reaches 0.5 cm, the spring 93 starts to press down.

[0051] When working, the weight of the snow with a thickness of 0.5 cm on the upper end of the reflecting plate 7 is not less than 3 Kg, and the snow with a thickness of 0.5 cm can completely cover the reflecting plate 7, when the depth of the snow on the upper end of the reflecting plate 7 is greater than or equal to 0.5 cm, the spring 93 starts to press down, and it is to be explained that the average density of the snow is 0.2-0.25 g / cm3, and the weight of the snow is equal to the volume of the snow*0.2.

[0052] Example two, please refer to Figures 2 to 5 :

[0053] As an embodiment of the present application, as shown in Figures 2 to 5As shown in the figure, the snow removing mechanism 9 comprises a chute 111, the upper inner wall of the front and rear ends of the curved box 8 is provided with the chute 111, the inside of the chute 111 is fixedly connected with a spiral rod 113, the outer side of the spiral rod 113 is movably connected with a reciprocating motor 114 on the side away from the support rod 4, the side close to each other of the two reciprocating motors 114 is fixedly connected with a connecting rod 115, the side close to each other of the connecting rod 115 is fixedly connected with a snow pushing stick 11, the inner surface of the side away from the support rod 4 of the curved box 8 is movably connected with a trigger point 112 below the reflector 7, the left side of the trigger point 112 is fixedly connected with a connecting line in the inside of the curved box, and the connecting line is fixedly connected with the reciprocating motor 114 through the retraction disc spring.

[0054] When working, after the snow falls on the reflector 7, the reflector 7 is pressed downward by the snow and starts to move downward, when the reflector 7 presses the trigger point 112, the movement signal is transmitted to the reciprocating motor 114 through the connecting line, after receiving the movement information, the reciprocating motor 114 starts to move along the outer side of the spiral rod 113 to the side close to the support rod 4 in the chute 111, the reciprocating motor 114 drives the connecting rod 115 to move at the same time, the connecting rod 115 drives the snow pushing stick 11 to move, the snow pushing stick 11 pushes the snow on the reflector 7 to the side close to the support rod 4 at the same time, and the reciprocating motor 114 drives the connecting line to move at the same time, as the connecting line gradually lengthens, the disc spring in the retraction disc spring contracts, after the reciprocating motor 114 drives the snow pushing stick 11 to push the snow away from the reflector 7, the reciprocating motor 114 drives the snow pushing stick 11 to move to the side away from the support rod 4, the retraction disc spring does not have the pulling force of the reciprocating motor 114, as the reciprocating motor 114 moves back, the disc spring in the retraction disc spring starts to expand and pulls the connecting line back to the inside of the retraction disc spring, after the reciprocating motor 114 returns to the original position, the reflector 7 instantaneously rebounds to the upper end of the curved box 8 under the elastic force of the spring 93, and waits for the next snow removing work, the setting of the snow removing mechanism 9 can effectively remove the snow on the reflector 7, so that the surface of the reflector 7 can normally reflect sunlight.

[0055] As an embodiment of the present application, as shown in the figure, Figure 4 The two sides of the reciprocating motor 114 are fixedly connected with the folding rubber 12 between the chute 111;

[0056] When working, the folding rubber 12 is fixedly connected between the two sides of the reciprocating motor 114 and the chute 111, which can effectively prevent the snow from falling into the inside of the chute 111, when the snow enters the inside of the chute 111, it blocks the inside of the chute 111, which affects the reciprocating movement of the reciprocating motor 114, and further affects the snow removing work of the snow removing mechanism 9.

[0057] As an embodiment of the present application, as shown in the figure,Figures 2 to 3 As shown in the figure, the distance between the trigger point 112 and the upper end surface of the reflector 7 is equal to the width of the snow pushing stick 11.

[0058] In operation, the distance between the trigger point 112 and the upper end surface of the reflector 7 is equal to the width of the snow pushing stick 11, so that the snow pushing stick 11 can normally push snow after the reflector 7 is pressed down.

[0059] As an embodiment of the present application, as shown in the figure, Figures 5 to 6 As shown in the figure, the lower end of the snow pushing stick 11 is provided with an arc groove 14, the lower end of the snow pushing stick 11 is fixedly connected with a fixed rod 15 inside the arc groove 14, and the outer side of the fixed rod 15 is movably connected with a reverse pushing plate 13.

[0060] In operation, when the snow pushing stick 11 moves to the side close to the support rod 4 with the reciprocating motor 114, the snow pushing stick 11 drives the fixed rod 15 to move, and the reverse pushing plate 13 movably connected with the fixed rod 15 moves together. When the snow is pushed to the right side, the left side of the reverse pushing plate 13 is clamped to push the snow away from the surface of the reflector 7. When the snow pushing stick 11 moves away from the support rod 4 with the reciprocating motor 114, the reverse pushing plate 13 will deviate and rotate to the right side of the arc groove 14 due to friction force because of the close contact with the reflector 7, so as to remove the snow falling on the reflector 7 again, effectively solving the technical problem that the snow falling on the reflector 7 cannot be removed when the snow pushing stick 11 moves away from the support rod 4.

[0061] Working principle:

[0062] In operation, the automatic positioning heat source system controls the rotation of the rotating column 1, which drives the fixed plate 2 to rotate, the fixed plate 2 drives the support frame 3 to rotate, the support frame 3 drives the curved box 8 to rotate, the curved box 8 drives the light-reflecting plate 7 to rotate, the rotating column 1 drives the light-reflecting plate 7 to rotate while also driving the support rod 4 to rotate, the support rod 4 drives the fixed ring 5 to rotate, the fixed ring 5 drives the heated pipe 6 to rotate, after the light-reflecting plate 7 is perpendicular to the sunlight, the light-reflecting plate 7 reflects the sunlight to the surface of the heated pipe 6 to heat the heated pipe 6, the heat energy of the heated pipe 6 is transmitted to the heated medium in the heated pipe 6 through heat transfer, the snow-removing mechanism 9 is arranged in the curved box 8, which effectively ensures that the snow on the light-reflecting plate 7 can be effectively removed, thereby ensuring that the light-reflecting plate 7 can normally reflect sunlight in snowy weather; after the snow falls on the light-reflecting plate 7, the light-reflecting plate 7 is pressed downward by the snow and starts to move downward, the light-reflecting plate 7 moving downward drives the positive electrode 91 to move to the lower end, at the same time, the spring 93 is forced to be squeezed downward, when the light-reflecting plate 7 drives the positive electrode 91 to contact the negative electrode 92 of the power supply, the positive electrode 91 and the negative electrode 92 are in electrical connection, the heating plate 94 starts to heat rapidly, the heat energy on the heating plate 94 is transmitted to the light-reflecting plate 7 through heat transfer, the snow covering the light-reflecting plate 7 rapidly melts after absorbing the heat energy on the light-reflecting plate 7, the snow melted into water slides down the curved light-reflecting plate 7, the snow-removing mechanism 9 arranged in the curved box 8 effectively ensures that the snow on the light-reflecting plate 7 can be effectively removed after the light-reflecting plate 7 is covered with snow, and the light-reflecting plate 7 returns to normal to reflect sunlight; the elastic sealing rubber 10 is fixedly connected between the lower end of the light-reflecting plate 7 and the curved box 8 on the side close to the support rod 4, which can seal the inside of the curved box 8 while the snow-removing mechanism 9 is working, so as to avoid impurities and water entering the inside of the curved box 8, the impurities or water entering the curved box 8 will damage the structure in the inside of the curved box 8 to some extent, and may cause the heating plate 94, the positive electrode 91 and the negative electrode 92 in the inside of the curved box 8 to be short-circuited and burnt out, thereby affecting the snow-removing work; after the snow on the upper end of the light-reflecting plate 7 is removed, only if the total spring force of the spring 93 is greater than the gravity of the light-reflecting plate 7, the light-reflecting plate 7 can normally rebound to the original position to complete the next snow-removing work; the heating temperature of the heating plate 94 cannot be higher than 100 degrees, which can avoid the elastic sealing rubber 10 from cracking or deforming due to high temperature, thereby affecting the sealing effect and the normal snow-removing work; the weight of the snow with a thickness of 0.5 cm on the upper end of the light-reflecting plate 7 is not less than 3 Kg, and the snow with a thickness of 0.5 cm can completely cover the light-reflecting plate 7, when the depth of the snow on the upper end of the light-reflecting plate 7 is greater than or equal to 0.5 cm, the spring 93 starts to press downward, it should be noted that the average density of snow is 0.2-0.25 g / cm3, and the weight of snow is equal to the volume of snow*1*0.2; When the snow falls on the reflector 7, the reflector 7 is pressed by the snow to the lower end and starts to move downward, when the reflector 7 is pressed to the trigger point 112, the movement signal is transmitted to the reciprocating motor 114 through the connecting line, after receiving the movement information, the reciprocating motor 114 starts to move along the outside of the spiral rod 113 in the slide groove 111 to the side close to the support rod 4, the reciprocating motor 114 drives the connecting rod 115 to move at the same time, the connecting rod 115 drives the snow shovel 11 to move, the snow shovel 11 moves at the same time to push the snow on the reflector 7 to the side close to the support rod 4, at the same time, the reciprocating motor 114 pulls the connecting line to move, as the connecting line is gradually lengthened, the disc spring in the retracting disc spring is retracted, after the reciprocating motor 114 drives the snow shovel 11 to push the snow away from the reflector 7, the reciprocating motor 114 drives the snow shovel 11 to move to the side away from the support rod 4, the retracting disc spring has no pulling force of the reciprocating motor 114, as the reciprocating motor 114 moves back, the disc spring in the retracting disc spring starts to expand and pulls the connecting line back to the inside of the retracting disc spring, after the reciprocating motor 114 returns to the original position, the reflector 7 rebounds to the upper end of the curved box 8 under the elastic force of the spring 93, waiting for the next snow removal work, the snow removal mechanism 9 can effectively remove the snow on the reflector 7, so that the surface of the reflector 7 can normally reflect sunlight; The distance between the trigger point 112 and the upper surface of the reflector 7 is equal to the width of the snow shovel 11, which can normally push the snow when the reflector 7 is pressed; When the reciprocating motor 114 moves to the side close to the support rod 4, the snow shovel 11 drives the fixed rod 15 to move, the anti-push plate 13 movably connected to the fixed rod 15 moves together, because the left side of the anti-push plate 13 is stuck when pushing the snow to the right side, it can push the snow away from the surface of the reflector 7, when the reciprocating motor 114 drives the snow shovel 11 to move to the side away from the support rod 4, the anti-push plate 13 will deviate and rotate to the right side of the arc groove 14 due to friction, which can remove the snow falling on the reflector 7 again, effectively solving the technical problem that the snow falling on the reflector 7 cannot be removed when the snow shovel 11 moves to the side away from the support rod 4.
