Technical Field
[0001] The invention belongs to the technical field of rainproof equipment, in particular to a rainproof shed for stacking wooden rafters of ancient buildings. Background Art Wooden rafters, also known as rafters, are long wooden strips placed on purlins to support roof panels and tiles. They are mainly used in ancient buildings.
[0002] Among them, wooden rafters are installed on ancient buildings and are often stacked on one side. Due to their wooden structure, they cannot be exposed to rain. Therefore, when they are stacked, they need to be covered with waterproof cloth when it rains.
[0003] When using waterproof cloth to cover the roof during rain, the staff usually pulls the waterproof cloth to cover it. This method not only consumes the staff's physical strength, but also takes a long time to cover, resulting in the wooden rafters being exposed to the rain. Summary of the invention

[0006] When the present application is in use, the waterproof cloth is folded along a W wave shape, which can ensure that the waterproof cloth can be unfolded when pulled, and the wooden rafters are located on both sides close to the pillars and are arranged longitudinally. When it is not raining, the moving block is located in the chute and the slider contacts the iron sheet, which is attracted by the first electromagnet and compresses the spring. When it rains, the staff controls the first electromagnet to cut off the power, so that the iron sheet and the slider pop out under the action of the spring, wherein the iron sheet is pulled back by the spring, and the slider slides out of the chute. When the slider slides out of the chute, it drives the rainproof cloth to open, so that the rainproof cloth covers the wooden rafters, and the wooden rafters can be quickly covered, which not only saves the physical strength of the staff, but also reduces the wooden rafters from being wetted by rain.

[0023] A method for unfolding a rainproof awning for stacking wooden rafters of an ancient building comprises the following steps: (1) wooden rafters are placed on both sides of a column 1 and arranged longitudinally, and the rainproof awning is unfolded. When it rains, the first electromagnet 8 is powered off and the second electromagnet 14 is powered on. After the first electromagnet 8 is powered off, it no longer attracts the iron sheet 7. The iron sheet 7 pops out under the action of a spring 5. The movement of the iron sheet 7 pushes a slider 4 to move synchronously with acceleration. The iron sheet 7 is fixedly arranged on the spring 5 and will not move out of the slide groove 3. The slider 4 moves out along the slide groove 3 and performs a parabolic motion after moving out of the slide groove 3. Thus, the slider 4 drives the rainproof cloth to open and drives the second wire roller to move upward. Under the action of the second electromagnet 14, the second guide roller 11 is attracted so that the rainproof cloth is unfolded and laid on the wooden rafters. (2) To fold up the rainproof cloth, first insert the slider 4 into the slide groove 3, then turn off the power to the second electromagnet 14 and turn on the power to the first electromagnet 8. After the second electromagnet 14 is turned off, the second guide roller 11 falls down and lands on the rainproof cloth. Then the staff presses down the second guide roller 11 in turn, so that the rainproof cloth is folded in a W wave shape.
[0024] The use of the present application can cut off the power to the first electromagnet 8 when it rains, and then the slider 4 quickly pops out of the slide groove 3 and falls to the ground under the action of the spring 5. The slider 4 pulls the rainproof cloth to move synchronously when sliding, thereby realizing the opening of the rainproof cloth and covering the wooden rafters with the rainproof cloth.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
