Detailed Description
The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings.
The invention provides a system for adjusting the illumination intensity of a glass dome, which comprises two parallel glass layers 1 arranged at intervals as shown in figure 1, wherein the glass layers 1 are arranged on a roof and are sealed at the periphery, and a cavity 2 for injecting liquid is formed between the glass layers 1. The two opposite sides of the cavity 2 are respectively communicated with a first vacuum bottle 3 and a second vacuum bottle 4 through water pipes, and a water pump 5 is arranged between the first vacuum bottle 3 and the cavity 2.
The first vacuum bottle 3 is filled with at least two layered liquids with different light transmittance, and the cavity 2 is filled with the liquid in the first vacuum bottle 3. For aesthetic reasons, the first vacuum flask 3, the cavity 2 and the second vacuum flask 4 must be free from air bubbles or may be present in small amounts. In the embodiment of the invention, the glass layer 1 is inclined upwards towards the second vacuum bottle 4, so that layered liquids with different light transmittances can move upwards or upwards along the glass layer 1 under the driving of the water pump 5, and only one liquid with one light transmittance is ensured in the cavity 2 after the liquid is switched in the cavity 2. If the glass layer 1 is kept horizontal, however, it is not allowed that stratified liquids of different light transmittances are caused to form layers in the vertical direction in the cavity 2.
A light intensity sensing device 6 is installed on a light facing surface of the glass layer 1 on the upper layer in the glass layer 1, and outputs a light intensity signal, and in the embodiment of the present invention, the light intensity sensing device 6 is a light sensor. The light intensity sensing device 6 is connected with a processor 7, and the processor 7 is connected with the water pump 5 and controls the water pump 5. In an embodiment of the invention, the water pump 5 is a double suction pump, which can suck liquid into the first vacuum flask 3 or discharge liquid from the first vacuum flask 3.
The liquid with the light transmittance corresponding to the light intensity signal is preset in the processor 7, and specifically, the light intensity ranges equal to the light transmittance types of the liquid are preset in the processor 7, the light intensity ranges are adjacent, and the light intensity ranges correspond to the liquid one by one. In the embodiment of the present invention, the adjacent illumination intensity ranges are specifically half-open and half-closed intervals, and are both in a front-open and back-closed state or a front-closed and back-open state, and in two adjacent illumination intensity ranges, the high end value of the front illumination intensity range coincides with the low end value of the back illumination intensity range.
As shown in fig. 2, the first vacuum bottle 3 includes a first bottle body 31 and a first piston 32 sliding in the first bottle body 31, and a first vent 33 is formed at the bottom of the first bottle body 31. Referring to fig. 3, the second vacuum bottle 4 has the same structure as the first vacuum bottle 3, and includes a second bottle body 41 and a second piston 42 sliding in the second bottle body 41, and a second vent 43 is formed at the bottom of the second bottle body 41.
With reference to fig. 3, the working principle of the present invention is as follows: take 3 liquids with different transmittances and layered as an example. Firstly, 3 kinds of light transmittance and layered liquid are filled in the first vacuum bottle 3, and the adopted layered liquid can be as follows from top to bottom: carbon disulfide solution, saturated saline and carbon tetrachloride solution. And mixing the three solutions with pigments with the same color, and adjusting the concentration of the pigments to ensure that the three solutions have different color depths, so that the three solutions have different light transmittances, wherein the solution with the lightest color has the highest light transmittance and the solution with the darkest color has the lowest light transmittance. And the color of the solution goes from light to dark from top to bottom. In other embodiments, pigments with different colors may be mixed with the solutions, as long as the light transmittances of the three solutions are different, and the light transmittances of the three solutions may not be from top to bottom, from bottom to top, or irregularly. For the purpose of explaining the principle of the present invention, taking blue as an example, the color of the layered solution is light blue, blue and dark blue from top to bottom, when the layered solution is filled in the first vacuum bottle 3, the solution in the cavity 2 is light blue, the second vacuum bottle 4 is empty of solution, and the second piston 42 is located at the uppermost position in the second bottle body 41. When the intensity of the light sensed by the light intensity sensing device 6 is weaker, the solution in the cavity 2 is light blue. When the light intensity is moderate, the water pump 5 pumps the solution in the first vacuum bottle 3 out of the cavity 2, the first piston 32 of the first vacuum bottle 3 moves upwards, the second piston 42 of the second vacuum bottle 4 moves downwards, the blue solution is squeezed into the cavity 2, and the light blue solution is squeezed into the second vacuum bottle 4. When the illumination intensity is strong, the water pump 5 continues to pump the solution in the first vacuum bottle 3 into the cavity 2, at this time, the first piston 32 of the first vacuum bottle 3 moves upward, the second piston 42 of the second vacuum bottle 4 moves downward, the dark blue solution is squeezed into the cavity 2, and the blue solution is squeezed into the second vacuum bottle 4. The method for filling the cavity 2 with only one light transmittance solution is as follows: the starting time of the water pump 5 is preset, and the water pump 5 is controlled to be started in the preset time. The opening time of the water pump 5 is determined through experimental calculation. Because the flow rate of the water pump 5 is fixed, the flow of the water pump 5 can be controlled by controlling the starting time of the water pump 5, so that the solution in the cavity 2 can be kept in the state of only one light transmittance solution when the water pump 5 stops working.
The invention also provides a method for adjusting the illumination intensity of the glass dome, which comprises the following steps:
s1: obtaining the illumination intensity of the light-facing surface of the glass layer 1 positioned on the upper layer in the glass layer 1;
s2: and injecting liquid with light transmittance corresponding to the illumination intensity into the cavity 2 according to the illumination intensity.
