[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-6 As shown in the figure, this embodiment provides an example of a building drainage device.
[0026] A building drainage device includes a support frame 1, with a drainage device body 2 fixedly installed inside the support frame 1. A flexible hose 3 connected to the drainage device body 2 is provided on one side of the support frame 1. A suction tube 4 is fixedly installed at one end of the flexible hose 3, and a filter screen 5 is provided on the suction tube 4. A cleaning mechanism 6 is provided on the filter screen 5. The cleaning mechanism 6 includes a sealing frame 7 fixedly installed on the inner side of the filter screen 5, a battery 8 fixedly installed on the inner wall of the sealing frame 7, and a motor 9 connected to the battery 8 fixedly installed inside the sealing frame 7. A cleaning brush 10 that is in contact with the surface of the filter screen 5 is fixedly installed on the output end of the motor 9. Through the setting of the cleaning mechanism 6, one side of the filter screen 5 can be cleaned during drainage. The suction tube 4 and the flexible hose 3 are placed into the foundation, and the drainage device body 2 is started to drain water. During drainage, the motor 9 is started to drive the cleaning brush 10 to rotate on one side of the filter screen 5. The rotating cleaning brush 10 can clean the filter screen 5, thereby preventing the accumulation of mud and sand on one side of the filter screen 5, thus preventing the filter screen 5 from becoming clogged, and ensuring that the drainage efficiency is not affected.
[0027] In this embodiment, as Figures 1-6As shown, multiple screws 11 are evenly installed on the filter screen 5, multiple threaded holes 12 are evenly opened on the suction tube 4, two fixing plates 13 are provided on the top of the support frame 1, a support rod 14 is fixedly installed between the two fixing plates 13, two fixing blocks 15 are symmetrically fixedly installed on the fixing plate 13 at the top of the support rod 14, a limit rod 16 is slidably installed on the fixing block 15, and two limit blocks 17 are symmetrically fixedly installed on the fixing plate 13 at the bottom of the support rod 14. By using screws 11 and threaded holes 12, the filter screen 5 is installed on the suction tube 4 using multiple screws 11, allowing the filter screen 5 to be removed from the suction tube 4. This not only facilitates the maintenance of the motor 9 in the sealing frame 7, but also allows for the replacement of the filter screen 5 when it is damaged. By using the fixing plate 13 and the support rod 14, the hose 3 can be easily wound and rolled up when there is no drainage, so as to collect and place it. By using the fixing block 15, the limiting rod 16 and the limiting block 17, after the hose 3 is wound around the support rod 14, the limiting rod 16 is pushed down and its bottom is inserted into the limiting block 17, thereby limiting the wound hose 3 to prevent it from falling off.
[0028] In this embodiment, as Figures 1-6 As shown, a first magnetic block 18 is fixedly installed on the surface of the limiting rod 16, a second magnetic block 19 is fixedly installed on the surface of the fixing block 15 and the limiting block 17, a handle 20 is fixedly installed on the top of the two limiting rods 16, two support plates 21 are symmetrically fixedly installed on the surface of the support frame 1, a screw 22 is installed on the support plate 21, and a drill bit 23 is fixedly installed at the bottom of the screw 22. By setting the first magnetic block 18 and the second magnetic block 19, after the limiting rod 16 is connected to the limiting block 17, the first magnetic block 18 and the second magnetic block 19 on the limiting block 17 adhere to each other and attract each other, which can fix the limiting rod 16 to prevent it from loosening. After the limiting rod 16 is pulled up, the first magnetic block 18 adheres to the second magnetic block 19 on the fixing block 15, which can fix the limiting rod 16 so as to wind and wrap the hose 3. The handle 20 makes it easy to pull the two limiting rods 16 at the same time. After the support plate 21, screw 22 and drill bit 23 are set up, the support frame 1 is supported and placed. Rotating the screw 22 pushes the drill bit 23 down into the ground. After the drill bit 23 and screw 22 are inserted into the ground, they can provide stable support for the support frame 1 and prevent the support frame 1 from falling into the foundation during the drainage process.
[0029] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a building drainage device provided in this embodiment is as follows:
[0030] Place the straw 4 and hose 3 into the foundation, and start the drainage device body 2 to drain the water. When draining, start the motor 9 to drive the cleaning brush 10 to rotate on one side of the filter screen 5. The rotating cleaning brush 10 can clean the filter screen 5, thereby preventing mud and sand from accumulating on one side of the filter screen 5 and thus preventing the filter screen 5 from becoming clogged.
[0031] In summary, in this embodiment, a building drainage device uses screws 11 and threaded holes 12 to install the filter screen 5 onto the suction pipe 4, allowing the filter screen 5 to be removed from the suction pipe 4. This facilitates maintenance of the motor 9 in the sealing frame 7 and allows for replacement of the filter screen 5 when it is damaged. The fixing plate 13 and support rod 14 allow for easy winding and coiling of the hose 3 when drainage is not in progress, facilitating collection and placement. The fixing block 15, limiting rod 16, and limiting block 17 allow the hose 3 to be wound around the support rod 14, and then the limiting rod 16 is pushed down and its bottom is inserted into the limiting block 17, thus limiting the wound hose 3 to prevent it from falling off. The first magnetic block 1... The setting of the second magnetic block 19 and the setting of the limiting rod 16 and the limiting block 17, at this time, the first magnetic block 18 and the second magnetic block 19 on the limiting block 17 can adhere and attract to fix the limiting rod 16 to prevent loosening. After the limiting rod 16 is pulled up, the first magnetic block 18 and the second magnetic block 19 on the fixing block 15 can adhere to fix the limiting rod 16 so as to wind and wrap the hose 3. The setting of the handle 20 makes it easy to pull the two limiting rods 16 at the same time. After the support plate 21, screw 22 and drill bit 23 are set up, the support frame 1 is supported and placed. The screw 22 is rotated to push the drill bit 23 down into the ground. After the drill bit 23 and screw 22 are inserted into the ground, they can provide stable support for the support frame 1 and prevent the support frame 1 from falling into the foundation during the drainage process.
