Description

Technical Field

[0001] The utility model relates to the technical field of building drainage, and more specifically to a water accumulation drainage device. Background Art

[0002] With the improvement of the requirements for comfort and convenience in buildings, same-floor drainage has gradually become the mainstream drainage method for bathrooms in residential buildings; at the same time, in order to meet the functional requirements of the lower floors of buildings, in many cases, same-floor drainage also needs to be adopted on this floor.

[0003] While same-floor drainage brings comfort and convenience, it is often not easy to detect pipeline leakage or the failure of the floor waterproof layer to leak water in the sunken area in time. The accumulated water in the sunken box also affects the hygiene of the building environment and poses a threat to the health of personnel. The traditional solution is to set up secondary drainage facilities in the sunken area to only drain the accumulated water, but it cannot remind the management personnel to carry out maintenance, which easily causes the sunken box to be in a wet state for a long time and breed bacteria.

[0004] Therefore, it is necessary to provide a water accumulation drainage device to at least partially solve the above problems. Summary of the Utility Model

[0005] A series of simplified concepts are introduced in the summary of the utility model part, which will be further described in detail in the specific implementation part. The summary of the utility model part does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0006] To at least partially solve the above problems, the utility model provides a water accumulation drainage device, including:

[0009] A water immersion sensor, the water immersion sensor is arranged in the first accommodation cavity.

[0010] According to the water accumulation drainage device of the present utility model, the main body part can effectively collect water accumulation and direct the water accumulation to the drainage system through the water outlet. The water outlet part enables the water accumulation collected from the main body part to flow into the drain pipe orderly. The water immersion sensor can directly sense the presence and water level change of the water accumulation, and has high accuracy and timeliness in alarming. In this solution, while ensuring the smoothness of drainage, the alarming function is realized. This solution directly connects the water accumulation drainage device to the inlet end of the drain pipe of the caisson, ensuring that the water accumulation can be discharged into the drainage system along the shortest path after being collected, avoiding the retention of water accumulation inside the water accumulation drainage device, reducing the resistance and time in the drainage process, improving the drainage efficiency, thereby preventing excessive water accumulation in the caisson and reducing the pressure on the waterproof layer.

[0046] Unless otherwise specified, the numerical ranges in this text include not only the entire range within its two endpoints, but also several sub-ranges included therein.

[0047] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present utility model is thorough and complete, and the concepts of these exemplary embodiments are fully conveyed to those of ordinary skill in the art.

[0048] Referring to Figures 1 - 2 , the present utility model provides a water accumulation drainage device, including a main body portion 10, a water outlet portion 20, and a water immersion sensor 30.

[0049] The main body portion 10 has a first accommodation cavity 11, as well as a water inlet 12 and a water outlet 13 that communicate with the first accommodation cavity 11. The water inlet 12 and the water outlet 13 are arranged at intervals along the circumferential direction of the main body portion 10. Through the arrangement of the main body portion 10, it is possible to effectively collect the accumulated water from different positions of the caisson and direct the accumulated water to the drainage system through the water outlet 13.

[0050] The water outlet portion 20 has a second accommodation cavity 21. The inlet end of the water outlet portion 20 is connected to the main body portion 10. The second accommodation cavity 21 communicates with the first accommodation cavity 11 through the water outlet 13, and the outlet end of the water outlet portion 20 is used to be connected to the inlet end of the drain pipe 80 of the caisson. Through the arrangement of the water outlet portion 20, the accumulated water collected from the main body portion 10 can flow into the drain pipe 80 in an orderly manner, avoiding the backflow or leakage of the accumulated water during the drainage process.

[0051] The water immersion sensor 30 is disposed in the first accommodation cavity 11. By placing the water immersion sensor 30 inside the main body 10, the presence of accumulated water and the change in water level can be directly sensed, and the accuracy and timeliness of the alarm are high.

[0052] In this solution, while ensuring the smoothness of drainage, the alarm function is realized. The accumulated water drainage device is directly connected to the inlet end of the drain pipe 80 of the caisson, ensuring that the accumulated water can be discharged into the drainage system along the shortest path after being collected, avoiding the retention of accumulated water inside the accumulated water drainage device, reducing the resistance and time during the drainage process, improving the drainage efficiency, thereby preventing excessive accumulated water in the caisson and reducing the pressure on the waterproof layer.

[0053] Optionally, the main body 10 is configured as a hollow columnar structure. A relatively large space, i.e., the first accommodation cavity 11, is formed inside the hollow columnar structure. This enables the accumulated water drainage device to have a relatively small volume without affecting the accumulated water drainage effect. The water inlet 12 and the water outlet 13 are formed on the side wall of the main body 10.

[0054] In some embodiments of the present utility model, a plurality of water inlets 12 are arranged at intervals in the circumferential direction on the main body 10. The arrangement of the plurality of water inlets 12 can ensure that the accumulated water in the caisson is effectively collected from multiple directions, improving the accumulated water collection efficiency and reducing the retention time of the accumulated water in the caisson.

[0055] In some embodiments of the present utility model, the water inlet 12 is in a strip-shaped structure extending along the height direction DH, and the bottom wall of the water inlet 12 is flush with the leveling layer of the caisson. The leveling layer is located at the bottom of the caisson, and the setting of the leveling layer of the caisson is common knowledge in the art and will not be described in detail here. Since the strip-shaped structure has a certain extensibility in the height direction DH, it can adapt to accumulated water of different depths. In the case of continuously changing accumulated water depth, the strip-shaped water inlet can maintain a stable water inlet effect. In addition, the strip-shaped water inlet 12 has a smaller opening width compared to water inlets 12 of other shapes. When the accumulated water carries debris (such as soil, small stones, etc.) and flows through the water inlet 12, larger debris will be blocked outside the water inlet 12, reducing the probability of debris entering the accumulated water drainage device.

[0056] Optionally, the number, area, and distribution range of the water inlets 12 can be adjusted according to actual needs. The number, area, and distribution range of the water inlets 12 are not particularly limited in the present utility model.

[0057] The water outlet 13 is also provided on the side wall of the main body 10 and communicates with the first accommodation cavity 11 through the water outlet 13. The setting of the water outlet 13 enables the accumulated water to flow smoothly towards the drainage system without backflow or retention.

[0058] Generally, there is only one water outlet 13, corresponding to the drain pipe 80 of one caisson. Of course, in some embodiments, the water outlets 13 can be arranged at intervals as multiple ones, and the multiple water outlets 13 correspond to multiple drain pipes 80.

[0059] Optionally, the quantity, area and distribution range of the water outlet 13 can be adjusted according to actual requirements. The quantity, area and distribution range of the water outlet 13 are not particularly limited in the present utility model.

[0060] In this solution, the water inlet 12 and the water outlet 13 are arranged on the side wall of the main body 10, which is convenient for connecting with other pipes and components in the caisson. A good overall coordination is formed between the main body 10 with a hollow columnar structure and components such as the water inlet 12 and the water outlet 13. The connection between each component is tight and stable, and they can cooperate together to complete the tasks of collecting and draining accumulated water.

[0061] In some embodiments of the present utility model, the accumulated water drainage device further includes a filter screen 40. The filter screen 40 is arranged in the first accommodation cavity 11. The filter screen 40 is located between the water inlet 12 and the water immersion sensor 30, and the filter screen 40 is also located between the water outlet 13 and the water immersion sensor 30. The setting of the filter screen 40 can filter out impurities in the accumulated water and protect the water immersion sensor 30 from being polluted. Through the setting of the filter screen 40, a stable working environment is provided for the water immersion sensor 30 on the premise of not affecting the water inlet and drainage of the accumulated water drainage device.

[0062] It can be understood that the aperture of the filter screen 40 is smaller than that of the water inlet 12. In some embodiments, the filter screen 40 can be arranged at the water inlet 12, but due to the smaller aperture of the filter screen 40, the water inlet efficiency of the accumulated water drainage device will be affected.

[0063] In some embodiments of the present utility model, the filter screen 40 is arranged around the outer periphery of the water immersion sensor 30 along the circumferential direction, and the filter screen 40 is spaced from the water inlet 12 and the water outlet 13 respectively. The setting of the filter screen 40 can protect the water immersion sensor 30 in all directions and does not affect the drainage efficiency between the water inlet 12 and the water outlet 13.

[0064] In some embodiments of the present utility model, the accumulated water drainage device further includes a vertical pipe part 50. The vertical pipe part 50 is arranged above the main body 10. Through the setting of the vertical pipe part 50, it is convenient to repair and maintain the water immersion sensor 30 and the interior of the main body 10. Optionally, the vertical pipe part 50 is also constructed as a hollow columnar structure. Optionally, a third accommodation cavity 51 is formed in the vertical pipe part 50, and the third accommodation cavity 51 is communicated with the first accommodation cavity 11. Optionally, the length of the vertical pipe part 50 is set according to the depth of the dropped slab.

[0065] In some embodiments of the present utility model, the vertical pipe portion 50 is connected to the main body portion 10 by socket connection. The socket connection method is simple and reliable, facilitating installation and disassembly.

[0066] In some embodiments of the present utility model, the water accumulation drainage device further includes a cover plate 60, and the cover plate 60 is disposed on the top of the vertical pipe portion 50. The cover plate 60 is used to seal the top of the vertical pipe portion 50 to prevent foreign objects from entering the vertical pipe portion 50. Optionally, the cover plate 60 can be directly exposed on the ground, further improving the maintainability and operability of the water accumulation drainage device. Optionally, the cover plate 60 is made of a metal material such as stainless steel. Optionally, the cover plate 60 is connected to the vertical pipe portion 50 by a threaded connection.

[0067] In some embodiments of the present utility model, the cover plate 60 is provided with an opening hole 61. The opening hole 61 is used to open or close the cover plate 60, facilitating inspection and maintenance. Optionally, in practical applications, a special tool can be used to open or close the top cover through the top opening hole 61.

[0068] In some embodiments of the present utility model, the signal line 31 of the water immersion sensor 30 extends out of the water accumulation drainage device through the side wall of the vertical pipe portion 50. Leading the signal line 31 out from the side wall of the vertical pipe portion 50 simplifies the wiring process of the signal line 31 and improves the reliability of signal transmission. At the same time, since the vertical pipe portion 50 is located above the main body portion 10, the signal line 31 of the water immersion sensor 30 is led out from a high position, enhancing the overall safety performance of the device.

[0069] Optionally, the battery core of the water immersion sensor 30 is electrically connected or communicatively connected to a building automation system or a dedicated alarm through the signal line 31. When the water immersion sensor 30 detects water accumulation, a signal is transmitted to the building automation system or the dedicated alarm through the signal line 31 for alarm, reminding the staff that maintenance is required.

[0070] In some embodiments of the present utility model, the water accumulation drainage device further includes a baffle 70, and the baffle 70 is rotatably connected to the water outlet 13, and the baffle 70 covers the water outlet 13. Through the arrangement of the baffle 70, sewage in the drain pipe 80 is prevented from flowing back into the main body portion 10.

[0071] In some embodiments of the present utility model, the rotating shaft of the baffle 70 is connected to the upper part of the baffle 70, and the baffle 70 is inclined downward from top to bottom towards the outlet end of the water outlet portion 20. When water accumulates is discharged from the water outlet 13, the baffle 70 can be pushed open. In the case where no water accumulation is discharged, the baffle 70 can cover the water outlet 13 under the action of gravity.
