Description
Technical Field
[0001] The utility model relates to the technical field of sewage or wastewater drainage pipes in buildings, in particular to a drainage pipe buffer device based on a caisson. Background Art
[0002] When a bathroom with a caisson has multiple drainage points, the traditional practice is to install a trap at each drainage point. However, it was found during use that this can easily lead to the following problems: first, since the dry area floor drain and bathtub are rarely used, the water in the trap will evaporate and then smell bad; second, hair and other impurities and garbage are easily brought into the trap when taking a shower in the shower room. At the same time, the trap is blocked because the shower room has no drainage force. Utility Model Content
[0003] The purpose of the utility model is to provide a drainage pipe buffer device based on a caisson, which can replenish water to a single water trap through any water point in response to the above-mentioned problems and shortcomings, and can effectively solve the problem of water backflow in the floor drain during full-load drainage, and can also wash away impurities such as hair settled in the water trap through the siphon effect, and can also clean the water trap through the floor drain opening, while reducing the use of water trap accessories.
[0004] The technical solution adopted by the utility model is:
[0005] A drainage pipe buffer device based on a caisson comprises a drainage transverse pipe, a floor drain pipe and a water trap pre-buried in the caisson, wherein the lower end of the water trap is connected to a drainage main vertical pipe through a transverse pipe, and a four-way buffer connector is provided. The four-way buffer connector comprises a connector body, a transverse pipe opening arranged on one side of the connector body, an upper pipe opening arranged on the upper part of the connector body, a lower pipe opening arranged on the lower part of the connector body, and a buffer extension pipe horizontally and closedly arranged opposite to the transverse pipe opening. The transverse pipe opening is connected to the drainage transverse pipe, the upper pipe opening is connected to the floor drain pipe, and the lower pipe opening is connected to the water trap. The buffer extension pipe has a length of 150 mm-400 mm and a diameter of 50 mm-110 mm, and the outer side of the buffer extension pipe is set as a closed pipe opening.
[0006] Furthermore, the buffer extension tube and the connector body are made by integral injection molding of a mold. Alternatively, the four-way buffer connector includes a four-way connector and a separate buffer extension tube, one end of the buffer extension tube is open and the other end is closed, and the open end of the buffer extension tube is connected to the four-way connector. The connection method may be that the open end of the buffer extension tube is connected to the connecting pipe port of the four-way connector by sleeve and gluing or embedding and gluing. The connection method may also be that the open end of the buffer extension tube is connected to the connecting pipe port of the four-way connector by threading and gluing.
[0007] Furthermore, in order to save drainage transverse pipe materials and reduce interfaces with four-way buffer connectors, the drainage transverse pipe is provided with a plurality of oblique pipe openings, which are connected to transverse drainage branches. The angle between the transverse drainage branch pipe and the drainage transverse pipe is 45 degrees to 135 degrees.
[0008] Beneficial technical effects of the utility model:
[0009] An inserted horizontal cross with a buffer extension pipe is set at the floor drain of the caisson shower room to connect with the water trap, and the anti-gas odor return function of other sewage pipes in the bathroom is concentrated in the same water trap, which reduces the usage of water traps and the hidden danger of blockage caused by a single water trap. The water trap can be replenished with water from any point. The buffer extension pipe can effectively solve the problem of water backflow in the floor drain during full-load drainage, and can also flush away impurities such as hair deposited in the water trap through the siphon effect. The water trap can also be cleaned through the floor drain, effectively solving the problem of drainage pipe blockage in daily life. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is described in detail below in conjunction with the accompanying drawings.
[0017] Embodiment 1: Figure 1-6As shown, the utility model is a drainage pipe buffer device based on a caisson, comprising a drainage transverse pipe 3, a floor drain pipe 5, and a water trap 6 pre-buried in the caisson, the lower end of the water trap 6 is connected to the drainage main vertical pipe 7 through a transverse pipe, and a four-way buffer connector 4 is provided. The four-way buffer connector 4 includes a connector body, a transverse pipe opening arranged on one side of the connector body, an upper pipe opening arranged on the upper part of the connector body, a lower pipe opening arranged on the lower part of the connector body, and a buffer extension pipe 1 that is horizontally closed and arranged opposite to the transverse pipe opening, and the outer side of the buffer extension pipe 1 is set as a closed pipe opening. The transverse pipe opening is connected to the drainage transverse pipe 3, the upper pipe opening is connected to the floor drain pipe 5, and the lower pipe opening is connected to the water trap 6 to the drainage main vertical pipe 7. The horizontally closed buffer extension pipe 1 has a buffering function, so that the floor drain is prevented from overflowing under full-load drainage state.
[0018] In this embodiment, the buffer extension tube 1 has a length of 150 mm to 400 mm and a diameter of 50 mm to 110 mm. For example, the buffer extension tube 1 has a length of 150 mm, 180 mm, 200 mm, 250 mm, 300 mm, 350 mm, 400 mm and a diameter of 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 110 mm.
[0019] In this embodiment, the buffer extension tube 1 can be made by integral injection molding with the connector body. Figure 1-3 The four-way buffer connector 4 can also be made by connecting a four-way connector and a separate buffer extension tube 1. The separate buffer extension tube 1 is open at one end and closed at the other end. The open end of the buffer extension tube 1 is then connected to the four-way connector. The connection method can be as follows: Figure 4-5 As shown, the open end of the buffer extension tube 1 is connected to the connecting pipe opening of the cross-connector by means of sleeve-on and gluing or embedding-on and gluing. Figure 6 As shown, the open end of the buffer extension tube 1 is connected to the connecting pipe opening of the cross-connector by means of threads and gluing.
[0020] The buffer extension pipe 1 is provided in this embodiment to receive and slow down the wastewater flow rushing from the drainage transverse pipe 3, avoiding the direct impact of the wastewater flow on the inner wall of the four-way buffer connector 4 to cause backflow, thereby ensuring the hygiene of the bathroom. Therefore, the drainage transverse pipe 3 can not only be connected to a drain, but also be provided with multiple oblique pipe ports, which are connected to the horizontal drainage branch pipe 8, and the horizontal drainage branch pipe 8 is set at an angle of 45 degrees to 135 degrees with the drainage transverse pipe 3, such as 45 degrees, 90 degrees, and 135 degrees. It can meet the use of multiple floor drains with different functions, and is suitable for use in larger area bathrooms or water rooms.
[0021] In this embodiment, the lower end of the water trap 6 can be directly connected to the main drainage pipe 7 through the horizontal pipe 9 to drain water outward. Figure 1As shown, when a secondary drainage pipe 12 is provided in the caisson, the horizontal pipe 9 is connected to a tee 10, and the tee 10 is provided with an air inlet 11 in the caisson. Through the air circulation between the air inlet 11 in the caisson and the secondary drainage pipe 12, the blockage of the secondary drainage pipe 12 caused by the vacuum generated by the caisson is prevented. When the original building has only one drainage riser, the siphon principle can be fully utilized to make the feces discharge smoother, effectively separate the sewage and feces pipes, and at the same time, the secondary drainage pipe 12 can be lowered to the lowest point.
[0022] In this embodiment, the water trap 6 is used at the lower end of the floor drain in the wet area of the shower room, so that the sealing functions of multiple water traps required for multiple drainage points are concentrated in this water trap 6, reducing materials and workload.
[0023] Embodiment 2: Based on Embodiment 1, the inner wall of the buffer extension tube 1 can also be set to have several protruding triangular or trapezoidal spiral edges, which can serve as a reinforcing rib structure. The skeleton formed by it can respond quickly to the impact of water flow, and has higher strength and durability, so as to reduce the impact force of the water flow and slow down the water flow speed, while also reducing the noise in the pipeline.
[0024] The above embodiment is only one implementation of the utility model, but does not constitute a limitation. Any simple modification, change, substitution, combination, or simplification made without departing from the spirit of the utility model is equivalent to an equivalent replacement method and should be within the protection scope of the utility model.
