Description

Technical Field

[0001] The utility model relates to the technical field of emergency drainage devices installed on drainage risers, and specifically relates to an emergency drainage device installed on a drainage riser. Background Art

[0002] For building drainage, usually, the toilets on the first floor are drained separately, and those above the second floor are discharged outdoors through drainage risers. Due to various reasons, the bottom of the riser or the outlet pipe is often blocked, resulting in the backflow of sewage from the interface of the indoor sanitary ware on the upper floor, causing economic and mental losses to the owners. The property also only knows about the pipeline blockage after receiving complaints from the owners. By this time, it is already too late to clear the blockage. To deal with this situation, many developers have added drainage outlets to the drainage risers, but the drainage outlets are not provided with water seals and filters, which are prone to blockage and odor return, and are also very inconvenient to clean. Content of the Utility Model

[0003] The purpose of the utility model is to solve the above problems and propose an emergency drainage device that is anti-blocking, easy to clean, and does not return odor.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An emergency drainage device installed on a drainage riser includes a short pipe and a vertical plate. The top of the inner wall of the short pipe is fixedly connected to the top of the vertical plate. A knocking structure is connected to the inner wall of the vertical plate. The right side of the short pipe is communicated with a vertical pipe. The top of the vertical pipe is communicated with a sleeve. An opening and closing structure is connected to the upper left side of the sleeve. A partition is fixedly connected to the upper left side of the inner wall of the vertical pipe.

[0006] Preferably, the knocking structure includes a cross bar and a sheath. The outer wall of the cross bar is slidably clamped with the inner wall of the vertical plate. The left side of the outer wall of the cross bar is fixedly connected to the inner wall of the sheath. A groove plate is fixedly connected to the right side of the cross bar. A round block is slidably clamped in the inner wall of the groove plate. An indentation plate is fixedly connected to the end of the round block. A vertical rod is fixedly connected to the top of the indentation plate. The top of the outer wall of the vertical rod is slidably clamped with the top of the short pipe. A top plate is fixedly connected to the top of the vertical rod. A spring is sleeved on the upper part of the outer wall of the vertical rod. The two ends of the spring are respectively fixedly connected to the top of the short pipe and the bottom of the top plate.

[0007] Preferably, a joint is clamped on the left side of the outer wall of the short pipe, and a filter screen is inserted into the inner wall of the joint.

[0008] Preferably, a three-way pipe is pressed tightly against the left side of the filter screen, and the right side of the outer wall of the three-way pipe is threadedly connected to the inner wall of the joint.

[0009] Preferably, the opening and closing structure includes a bracket and a knob. The right side of the bracket is fixedly connected to the upper left side of the sleeve. The upper inner side of the bracket is rotatably connected to the outer wall of the knob, and a cover plate is fixedly connected to the right side of the knob.

[0010] Preferably, the bottom of the cover plate fits against the top of the sleeve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the accompanying drawings:

[0019] Embodiment 1:

[0020] Please refer to Figures 1-4: In this embodiment, an emergency drainage device installed on a drainage riser includes a short pipe 1 and a vertical plate 4. The top inner wall of the short pipe 1 is fixedly connected to the top of the vertical plate 4. A knocking structure 2 is connected to the inner wall of the vertical plate 4. The right side of the short pipe 1 is communicated with a vertical pipe 7. The top of the vertical pipe 7 is communicated with a sleeve 8. An opening and closing structure 3 is connected above the left side of the sleeve 8. A partition plate 9 is fixedly connected above the left side of the inner wall of the vertical pipe 7. The partition plate 9 divides the space in the vertical pipe 7 into two parts and forms a tight water seal with the accumulated water in the water seal cylinder.

[0021] The knocking structure 2 includes a cross bar 201 and a sheath 202. The outer wall of the cross bar 201 is slidably clamped with the inner wall of the vertical plate 4. The cross bar 201 slides left and right through the inner wall of the vertical plate 4 under force. The left side of the outer wall of the cross bar 201 is fixedly connected to the inner wall of the sheath 202. The sheath 202 is a rubber sleeve. A groove plate 203 is fixedly connected to the right side of the cross bar 201. A round block 204 is slidably clamped with the inner wall of the groove plate 203. The round block 204 slides up and down through the inner wall of the groove plate 203 under force. An indentation plate 205 is fixedly connected to the end of the round block 204. A vertical rod 206 is fixedly connected to the top of the indentation plate 205. The top of the outer wall of the vertical rod 206 is slidably clamped with the top of the short pipe 1. The vertical rod 206 slides up and down through the top of the short pipe 1 under force. A top plate 207 is fixedly connected to the top of the vertical rod 206. A spring 208 is sleeved on the upper part of the outer wall of the vertical rod 206. The two ends of the spring 208 are respectively fixedly connected to the top of the short pipe 1 and the bottom of the top plate 207. After the top plate 207 is forced to move downward, it rebounds by the elastic force of the spring 208.

[0022] By pressing the top plate 207 downward in the knocking structure 2, the vertical rod 206 is driven to move downward. The moving vertical rod 206 makes the indentation plate 205 drive the round block 205 to move downward. The moving round block 205 slides downward on the inner wall of the groove plate 203, so that the groove plate 203 drives the cross bar 201 to move to the right. Then the top plate 207 is released, and the spring 208 provides a return elastic force to make the top plate 207 drive the vertical rod 206 to move upward. Further, the indentation plate 205 cooperates with the round block 204 to drive the groove plate 203 to move to the left. The moving groove plate 203 makes the cross bar 201 drive the sheath 202 to knock the filter screen 10, and the attached impurities can be knocked off, reducing the use difficulty of the emergency drainage device and ensuring the drainage effect.

[0023] On the left side of the outer wall of the short pipe 1, there is a connector 5 clamped. Inside the inner wall of the connector 5, there is a filter screen 10 inserted. The filter screen 10 is made of stainless steel. On the left side of the filter screen 10, there is a three-way pipe 6 tightly abutted. On the right side of the outer wall of the three-way pipe 6, it is threadedly connected to the inner wall of the connector 5. The opening and closing structure 3 includes a bracket 301 and a knob 302. The right side of the bracket 301 is fixedly connected to the upper left side of the sleeve 8. The upper inner side of the bracket 301 is rotatably connected to the outer wall of the knob 302. The cover plate 303 can be pushed upward and rotated upward inside the bracket 301 through the knob 302. The right side of the knob 302 is fixedly connected to the cover plate 303. The bottom of the cover plate 303 fits with the top of the sleeve 8. The vertical pipe 7 should be made of a transparent material, such as transparent plastic or transparent resin, to facilitate observing the water seal situation in the water pipe.

[0024] Working principle:

[0025] When using this device, first connect the three-way pipe 6 to the external drainage riser. Under normal circumstances, the sewage in the riser flows downward along the pipe and flows along the pipe wall (the professional term is wall-attached flow). When the water flow reaches the position of the three-way pipe 6, a part of the water flow will flow onto the surface of the filter screen 10. The water filtered roughly by the filter screen 10 (the filter screen can prevent larger impurities) enters the vertical pipe 7 as the makeup water for the water seal, which can ensure that the odor in the riser will not overflow to the outside through the vertical pipe 7. At the same time, the cover plate 303 is on the top of the sleeve 8, which can not only ensure that the smell of the water seal itself does not spread, but also avoid the evaporation of water, preventing the water seal from drying out and failing. Once the discharge pipe is blocked, the sewage accumulates in the pipe until it enters this device. As the water surface rises, the sewage will push open the movable cover plate and overflow from the top of the sleeve 8, preventing backflow from the indoor of the upper floors and buying time for property maintenance. Press down the top plate 207, which will drive the vertical rod 206 to move downward. The moving vertical rod 206 makes the concave plate 205 drive the round block 205 to move downward. The moving round block 205 slides downward on the inner wall of the groove plate 203, so that the groove plate 203 drives the cross bar 201 to move to the right. Then release the top plate 207, and the spring 208 provides a restoring force to drive the top plate 207 to drive the vertical rod 206 to move upward, and then the concave plate 205 cooperates with the round block 204 to drive the groove plate 203 to move to the left. The moving groove plate 203 makes the cross bar 201 drive the sheath 202 to strike the filter screen 10, and the attached impurities can be knocked off.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-4 : In this embodiment, an emergency drainage device installed on a drainage riser further includes a bottom cover 11 and a handle 12. The inner wall of the bottom cover 11 is threadedly connected to the bottom of the outer wall of the vertical pipe 7. The bottom of the bottom cover 11 is fixedly connected to the top of the handle 12.

[0028] Working principle:

[0029] Holding the handle 12 and turning downward with the bottom cover 11 can gradually separate the bottom cover 11 from the bottom of the outer wall of the vertical pipe 7, facilitating the inspection of the inner wall of the vertical pipe 7.

[0030] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made within the scope of the claims.
