[0002] Steel structure workshops can provide a large space for production operations, enabling the safe and stable operation of production operations. Generally, the span of a steel structure roof is relatively large. Therefore, a drainage device needs to be set at the edge of the steel structure roof so that the roof of the steel structure workshop can drain rainwater in time when it rains, avoiding rainwater accumulation on the roof and causing leakage.

[0003] When the existing steel structure roof drainage device is in use, there is no device for filtering sundries in the rainwater collection tank, so that sundries on the upper side of the roof are easily carried into the rainwater collection tank along with the rainwater, and then the sundries block the rainwater collection hopper on the rainwater collection tank, affecting the drainage effect.

Through the set rainwater collection tank, strengthening rods, snap fasteners, grid, filter net, slots and clamping protrusions, the filter net on the grid can be snapped into the rainwater collection tank, so that the rainwater flowing in the rainwater collection tank is filtered by the filter net, avoiding sundries in the rainwater from entering the rainwater collection hopper and causing blockage, and ensuring the drainage effect.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5, this embodiment provides a technical solution: a steel structure roof drainage device, including a rainwater collection trough 1, on which reinforcing rods 2 are installed at equal intervals. On one side of the reinforcing rod 2, a grid 9 is installed. Below the grid 9, a filter screen 11 is installed. On the upper part of the grid 9, a snap-in 10 is integrally formed. At the connection position corresponding to the snap-in 10 on the reinforcing rod 2, a slot 12 is provided. On the vertical side surface inside the slot 12, a clamping protrusion 13 is integrally formed. Below the position of the reinforcing rod 2 corresponding to the rainwater collection trough 1, a connection seat 7 is installed. Below the connection seat 7, a rainwater guide pipe 4 is installed. At the upper end of the rainwater guide pipe 4, a rainwater collection funnel 8 is installed. On the inner side wall of the rainwater guide pipe 4, a rainwater guide strip 14 is provided.

[0021] As Figures 1-5 shown, the rainwater collection trough 1 is installed and fixed under the eaves of the steel structure roof through a support frame 3. The rainwater guide pipe 4, the horizontal pipe 5 and the vertical pipe 6 below the rainwater collection trough 1 are all fixed on the side wall of the steel structure through pipe clamps. The reinforcing rod 2 is fixed on one side of the upper flow position of the rainwater collection funnel 8 in the rainwater collection trough 1. When rainwater flows from the roof into the rainwater collection trough 1 and flows along the rainwater collection trough 1 towards the rainwater collection funnel 8, the filter screen 11 on the grid 9 below the reinforcing rod 2 can filter the sundries in the rainwater to avoid the sundries entering the rainwater collection funnel 8 and causing blockage, ensuring the drainage effect of the drainage device.

[0022] The lower end of the rainwater guide pipe 4 is connected to a horizontal pipe 5 through a tee joint. One end of the horizontal pipe 5 is connected to a vertical pipe 6 through a 90-degree elbow.

[0023] Support frames 3 are installed at equal intervals below the rainwater collection trough 1. The horizontal pipes 5 are connected through tee joints.

[0024] The reinforcing rod 2 is connected to the rainwater collection trough 1 by rivets. The reinforcing rod 2 is connected to the grid 9 through the slot 12 and the snap-in 10. The reinforcing rod 2 can strengthen and fix the upper side of the rainwater collection trough 1, and at the same time can support and fix the grid 9 and the filter screen 11.

[0025] The support frame 3 is connected to the rainwater collection trough 1 by bolts. The rainwater guide pipe 4 is hinged to the connection seat 7. The connection seat 7 is glued to the rainwater collection trough 1.

[0026] The rainwater collection funnel 8 is made of aluminum alloy profiles.

[0027] The working principle of a steel structure roof drainage device provided by the present utility model is as follows: As Figures 1-5As shown, during use, the rainwater collection trough 1 is fixedly installed under the eaves of the steel structure roof through the support frame 3. The rainwater guide pipes 4, horizontal pipes 5, and vertical pipes 6 on the lower side of the rainwater collection trough 1 are all fixed to the side wall of the steel structure through pipe clamps. The reinforcing rod 2 is fixed to one side of the upstream position of the rainwater collection hopper 8 in the rainwater collection trough 1. Rainwater flows from the roof into the rainwater collection trough 1. When the rainwater flows along the rainwater collection trough 1 towards the rainwater collection hopper 8, the filter screen 11 on the wire mesh rack 9 under the reinforcing rod 2 can filter the debris in the rainwater to prevent the debris from entering the rainwater collection hopper 8 and causing blockage, ensuring the drainage effect of the drainage device. The rainwater enters the inner side of the rainwater guide pipe 4 through the rainwater collection hopper 8 and flows downward along the rainwater guide strip 14 on the inner wall of the rainwater guide pipe 4. The rainwater guide strip 14 can timely discharge the air mixed in the rainwater upward. After the rainwater flows downward into the horizontal pipe 5, it continues to flow towards the vertical pipe 6. When the rainwater fills the horizontal pipe 5 and the rainwater collection hopper 8 is completely immersed in the rainwater, the drain pipe forms a siphon effect, which can quickly discharge the rainwater accumulated inside the rainwater collection trough 1.

[0028] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
