[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this document are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection and other existing methods, depending on actual needs.

[0029] See also Figures 1 to 4 The main structure of the device body is a drainage top 1, a support 2 and a support frame. The support frame is used to strengthen and fix the shape of the drainage top 1 to avoid deformation. The support 2 is used to support the drainage top 1. The support 2 is fixed to the roof of the bungalow, and the fixation can be achieved by grounding bolts.

[0030] In order to improve the life of the drainage top, the drainage top 1 is composed of a waterproof layer, an anti-permeability layer and a metal surface, wherein an anti-rust layer can be added by anti-rust paint or other conventional anti-rust materials, and the waterproof layer and the anti-permeability layer can be selected according to actual conditions by using existing technical means;

[0031] In order to prevent water from entering from the sides, the four sides of the drainage top 1 are rotatably connected with side covers 8 for wind and rain protection. When the side covers 8 are in the shielding state, they are tilted. The tilted setting can form a certain guiding effect on the wind to avoid vertical blowing and cause structural damage.

[0032] See also Figures 1 to 4 In order to collect rainwater in a centralized manner, a water collecting portion 3 is provided on the top of the drainage top 1, and the top of the drainage top 1 is a non-planar design;

[0033] The shape can be selected as follows: the top center of the drainage top 1 is concave, and the four lateral centers of the drainage top 1 are inclined slopes. At this time, the water collection part 3 is located in the concave center of the top, and rainwater is collected by natural falling.

[0034] The form can be selected as follows: the drainage top 1 is tilted on both sides to one side or directly tilted and equipped with an inner groove to guide rainwater to the water collection part 3;

[0035] One side of the water collecting part 3 is connected to a water storage tank 4, and the lower half of one side of the water collecting part 3 is connected to the water storage tank 4 through a pipeline to store rainwater.

[0036] See also Figures 1 to 4 In order to adapt to the snowy weather, a hollow tube 5 is arranged at the bottom of the drainage top 1, and a heating element 6 is placed inside the hollow tube 5. One end of the support 2 is threadedly connected with a spiral head 12 for taking out the heating element 6. Through the design of bolt connection, the spiral head 12 can be turned to take out the internal heating element 6;

[0037] In order to achieve adaptive heating, the bottom of the hollow tube 5 is connected to a touch-pressure rod 7, the bottom end of the touch-pressure rod 7 and the support 2 are connected by a tenon design, and the bottom end of the touch-pressure rod 7 is provided with an anti-drop limit part;

[0038] A pressure-sensitive switch 9 is provided at the inner bottom of the tenon of the support 2 and the pressure-touch rod 7. The pressure-touch rod 7 is provided with a wire groove for the wire to pass through. The pressure-sensitive switch 9 is electrically connected to the heating element 6 through the wire passing through the wire groove.

[0039] A compression spring 10 is bonded and fixed between the bottom end of the touch-pressure rod 7 and the support 2. A protruding touch-pressure head 11 is provided at the bottom center of the touch-pressure rod 7. The touch-pressure head 11 corresponds to the position of the pressure-sensitive switch 9.

[0040] When there is no snow accumulation, the elastic restoring force of the compression spring 10 prevents the pressure head 11 from contacting the pressure sensitive switch 9. An arc cover is bolted to one side of the pillar 2 for easy maintenance of the pressure sensitive switch 9. The compression spring 10 can be replaced and adjusted by opening the arc cover and lifting the drainage top 1 with a jack.

[0041] The above-mentioned components and electrical equipment are all existing technologies or existing feasible technologies. The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0042] How it works

[0043] When using the roof drainage structure, select the appropriate size, connect and assemble, and connect it to the roof of the bungalow by bolts (the side cover 8 needs to cover or correspond to the edge of the roof of the bungalow);

[0044] When it rains, rainwater falls on the top of the drainage top 1. Through the uneven design of the drainage top, the rainwater will flow to the water collection part 3 at the lower part. The water collection part 3 is connected to the water storage tank 4, so that the rainwater falls into the water storage tank 4 by natural gravity (a filter can be set inside the water storage tank 4 to filter the rainwater). The collected rainwater can be used for watering flowers, etc.

[0045] During the snowy season, snow falls to the top of the drainage top 1. When the snow is heavy and accumulates to a certain weight, it will press the touch-pressure rod 7, causing the touch-pressure head 11 to contact the pressure-sensitive switch 9, starting the heating element 6 to heat the hollow tube 5. Through heat conduction, the temperature of the drainage top 1 rises, further melting the snow and avoiding collapse of the drainage structure as a whole (here, the switch is also set to be actively opened according to actual conditions).

[0046] It should be noted that, in this article, relational terms such as one and two are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
