Description

Technical Field

[0001] The invention relates to the technical field of roof protection, in particular to a retractable protection device based on a roof structure layer and a construction method thereof. Background Art

[0002] Kanas, Hemu and Keketuohai in Altay, Xinjiang are tourist destinations. They are located in mountainous areas, with frequent severe snowstorms in winter, heavy rains in summer, and strong ultraviolet rays from the sun. The harsh climate has a great impact on the service life of the roof's waterproof layer. Most of the hotels in the scenic area are in the style of sloping roof cabins. The row of cabins has more roof gutters because their shapes must meet ecological needs. The roof shape is mostly welded into an overhead layer with galvanized keels. The surface layer is made of aluminum-magnesium-manganese plate layers with high strength and good load-bearing capacity as the finishing layer. The keel columns of the aluminum-magnesium-manganese plate layer are rooted in the structural layer to enhance its structural strength.

[0003] However, since the keel columns of the aluminum-magnesium-manganese plate finishing layer are rooted in the structural layer, the waterproof layer cannot be fully enclosed at the columns, which has a direct impact on the subsequent roof drainage and roof leakage prevention. The maintenance difficulty is much greater than that of ordinary buildings, and the cost is huge, especially the subsequent operation and maintenance costs are high.

[0004] The existing downspout design can only ensure that the aluminum-magnesium-manganese plate facing layer is not damaged and collects rain and snow water above the surface layer. However, the actual aluminum-magnesium-manganese plate facing layer is the empty layer of the roof light steel skeleton frame, and there is a gap of nearly 20 cm from the roof protection layer. The aluminum-magnesium-manganese plate layer is a plate splicing with joints. The joints are treated with weather-resistant glue in extremely cold areas. In winter, when extreme weather occurs frequently and there is a snowstorm of more than 1 meter, the aluminum-magnesium-manganese plate layer will be deformed due to excessive load. In summer, the temperature difference between day and night causes large expansion and contraction of the metal plate surface, and the joints will deform and produce gaps. In summer, there is heavy rainfall in mountainous areas, and water accumulates seriously inside the gutter. Only one downspout is designed, and the accumulated water under the aluminum-magnesium-manganese plate layer cannot be removed, causing leakage hazards. Once leakage occurs, it will bring a very bad experience to the occupants, the use function cannot be satisfied, and maintenance is also very difficult. The surface aluminum-magnesium-manganese plate layer must be removed first, and then the downspout is repaired, and the maintenance can only be done in summer. Compared with ordinary buildings, the difficulty and cost are very high;

[0005] Secondly, rainwater accompanied by debris entering the gutter can easily clog the drainage channel, making it impossible for the drainage channel to quickly drain rainwater, causing water accumulation on the roof. Due to the high location of the gutter, manual cleaning is very inconvenient and climbing operations are highly dangerous.

[0006] Therefore, the present invention proposes a retractable protective device based on a roof structure layer and a construction method thereof to solve the above-mentioned problems. Summary of the invention

[0022] Beneficial Effects

[0023] The present invention provides a retractable protective device for a roof structure layer and a construction method thereof. Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. A retractable protective device based on a roof structure layer and a construction method thereof, by increasing the original design of a surface drainage outlet to three drainage outlets with different elevations at the same part of the roof, the water accumulated between the roof layer, the waterproof layer and the structural layer can be discharged, that is, after the roof surface layer is damaged, the water accumulated in the gutter can be discharged from the second drainage outlet in time, and after the roof layer and the waterproof layer are damaged, the accumulated water can still be discharged through the third drainage outlet, reducing the functional impact of roof leakage on the owner, while extending the service life of the roof and reducing the later maintenance cost of the house.

There is no need to set a separate driving device for the rotation of the push rod, which saves the cost of setting a power device and makes the structure simpler, which is convenient for later inspection and maintenance work; secondly, the push rod is used to push the debris into the first debris collection component and the second debris collection component for collection and storage, and there is no need for frequent manual cleaning, which saves labor costs. Furthermore, by setting a wind power conversion component, the wind power can be used to drive the fan blades to rotate, thereby adding a new power source for driving the impeller to rotate, so that the impeller can have sufficient power to ensure that the push rod has the ability to push the debris to move; furthermore, the wind power conversion component can use wind power to provide power for the rotation of the first rotating shaft under rainless conditions, so that the first drainage outlet in the gutter can be continuously cleaned before the rainy season, ensuring the cleanliness of the first drainage outlet, and providing good conditions for smooth drainage.

By setting a first debris collection component and a second debris collection component, after debris such as fallen leaves fall into a collection barrel, the first pressing block and the second pressing block can be used to squeeze the debris, so that the volume of the debris is reduced, thereby providing sufficient collection space in the collection barrel, extending the time for cleaning the collection barrel, and the volume of the compressed debris is reduced, and the moisture inside the debris is squeezed out, making it easier to clean and transport, thereby reducing the time and labor cost of gutter cleaning.

[0056] Step 1: Roof layer drainage: Rainwater or snow water is collected into a plurality of gutters 5 along the inclined aluminum-magnesium-manganese plate layer 3. When the structure of the aluminum-magnesium-manganese plate layer 3 is not damaged, the rainwater or snow water enters the first drainage pipe 6 through the first drainage port, and is finally collected and discharged inside the drainage main pipe 9;

[0057] Step 2, debris treatment: When the roof layer discharges rainwater or snow water, the rainwater or snow water mixed with fallen leaves or other debris accumulated on the top of the aluminum-magnesium-manganese plate layer 3 is collected around the first drainage port in the gutter 5. Since the collected rainwater or snow water is concentrated and discharged through the first drainage port, the fast-flowing rainwater or snow water provides power for the operation of the debris treatment mechanism 11, and the debris treatment mechanism 11 collects the fallen leaves or other debris and then compresses them for treatment; the specific process is: after the rainwater or snow water is filtered by the first filter plate 1112, the water Mixed fallen leaves and other debris are blocked outside, while rainwater or snow water enters the water pipe 1111 through the first filter plate 1112, and is transported to the drainage main pipe 9 for discharge through the pipe connected to the first drainage pipe 6. When the rainwater or snow water collected in the gutter 5 enters the water pipe 1111, the impact force of the water flow and the gravity of the water jointly push the impeller 1114 to rotate. Since the impeller 1114 and the push rod 1119 are fixedly connected to the first transmission shaft 1113, the impeller 1114 is When the push rod 1119 rotates, the first transmission shaft 1113 is driven to rotate. When the push rod 1119 rotates, the fallen leaves and other debris gathered around the first drain outlet are pushed by the push rod 1119 to move. When the fallen leaves and other debris meet the collecting barrel 1121 during the movement, the fallen leaves or other debris fall into the collecting barrel 1121 under the action of gravity. Since the top of the first pressing block 1127 is provided with a circular through hole 1128, the fallen leaves or other debris pass through the circular through hole 1128 and the second pressing block 1129 and the first pressing block 1121. 7 enters the interior of the collecting tube 1121. When the push rod 1119 and the lifting column 1125 meet, the lifting column 1125 is pushed by the push rod 1119 and moves downward. At the same time, the first pressing block 1127 moves downward synchronously with the push rod 1119. After the fallen leaves or other debris in the collecting tube 1121 are squeezed by the first pressing block 1127, the water adsorbed in the debris is squeezed out, and the water enters the conical tube 1122 through the second filter plate 1123, and then flows into the water guide pipe 1111. When the second pressing block 1129 is blocked by fallen leaves or other debris during its downward movement, the guide rod 11210 moves upward along the lifting hole, and the gap between the second pressing block 1129 and the circular through hole 1128 becomes smaller, and the fallen leaves or other debris cannot pass through, which can achieve a better squeezing effect.The rainy season is usually accompanied by strong winds, and the wind pushes the fan blades 1143 to rotate, thereby driving the second transmission shaft 1142 to rotate. Since the first pulley 1145 and the second transmission shaft 1142 are fixedly connected, the first pulley 1145 rotates and transmits power to the second pulley 1147 through the transmission belt 1148. The micro generator 1146 converts wind energy into electrical energy when it rotates. A sealing cover is provided on the outside of the micro generator 1146 to prevent rainwater from entering, thereby keeping its working environment dry. The current is transmitted to the electromagnet 1149 through a wire. After the electromagnet 1149 is energized, it generates magnetic force and absorbs the ferromagnetic metal block 1117 upward. The first toothed disc 1116 and the second toothed disc 1144 are meshed with each other. The driving force generated by the second transmission shaft 1142 and the power of the rainwater pushing the impeller 1114 act on the first transmission shaft 1113 at the same time, and jointly push the first transmission shaft 1113 to rotate.

[0058] Step 3: Drainage of waterproof layer: When the aluminum-magnesium-manganese plate layer 3 is damaged, the leaked rainwater or snow water will be collected along the waterproof layer 4 to the second drainage port and enter the second drainage pipe 7 and then concentrated into the drainage main pipe 9 for discharge;

[0059] Step 3: Structural layer drainage: After the aluminum-magnesium-manganese plate layer 3 and the waterproof layer 4 are destroyed, the rainwater or snow water that has leaked onto the V-shaped structural layer 1 is collected in the third drainage port, and is concentrated into the drainage main pipe 9 through the third drainage pipe 8 for discharge.
