Description

Technical Field

[0001] The invention relates to a drainage water seal device. Background Art

[0002] According to the requirements for connecting balcony drainage in residential buildings to the outdoor sewage network, the drainage outlet pipe should be connected to the outdoor domestic sewage system. According to the drainage system requirements, water seal wells should be installed, and odor prevention facilities such as water seals should be installed on each floor.

[0003] In the current existing technology, the balcony drainage on each floor is equipped with a water-sealed floor drain, and after the horizontal branch pipes on each floor are gathered, a water-sealed well is set on the drainage horizontal main pipe, which brings about the problem of "double water seal". The "double water seal" problem will form an air plug, causing air blockage, poor drainage and drainage noise. However, if only a floor drain water seal is set on the balcony, if one of the users does not drain for a long time, toxic and harmful gases in the pipe will be injected into the room, and the indoor environmental hygiene and safety cannot be guaranteed; if only a water-sealed well is set on the drainage horizontal main pipe, it can only ensure that the toxic and harmful gases in the outdoor drainage pipe do not enter the vertical pipe, but it cannot ensure that the drainage systems of each household are isolated from each other. The usual practice is to first set up an inspection well on the drainage horizontal main pipe, and then set up a water-sealed well. However, there are many water and electricity pipelines on the first floor of a residential building, and it is difficult to arrange so many inspection wells. Summary of the Invention

[0039] Therefore, when the drainage from the balconies on each floor of the residents is collected and discharged to the horizontal main pipe after passing through the floor drain, the drainage enters the transition chamber and then enters the flow channel. Since the transition chamber and the flow channel are connected to the outside atmosphere, the "double water seal" problem can be solved, that is, the air resistance phenomenon is avoided; and the flow channel is connected to the water seal chamber, and the drainage enters the water seal chamber through the flow channel and is then discharged to the drainage treatment area for treatment.

[0040] Therefore, a drainage water seal device in an embodiment of the present invention solves the problem of double water seals, which causes poor drainage and drainage noise due to the air resistance phenomenon, through a drainage cavity, a transition cavity, a water inlet and a flow channel, and avoids the defects of setting up inspection wells and water seal wells, which result in many construction pipelines and great construction difficulty.

[0041] Example 2

[0042] In order to avoid the "double water seal" problem caused by the water seal floor drain and the water seal well, that is, to avoid the air blockage caused by the double water seal problem, which leads to poor drainage and drainage noise, and to avoid the problems of multiple construction pipelines and high construction difficulty caused by setting up inspection wells and water seal wells, the embodiment of the present invention provides a drainage water seal device, with reference to Figure 1 As shown, it includes: a drainage cavity 2, which is divided into a transition cavity and a water seal cavity in sequence along the direction of water flow; a transition cavity 3, which is connected to the outside atmosphere through one end of the drainage cavity; a horizontal main pipe 4, one end of which is used to be connected to the drainage floor drain, and the other end is arranged in the drainage cavity and connected to the transition cavity; and a flow groove 5, which is arranged in the transition cavity to connect the flow groove with the outside atmosphere; one end of the flow groove is connected to the other end of the horizontal main pipe, and the other end of the flow groove is connected to the water seal cavity.

[0043] refer to Figure 1 As shown, the drainage water seal device includes a drainage cavity 2; the left side of the drainage cavity 2 is a transition cavity 3, and the right side of the drainage cavity is a water seal cavity; further, the transition cavity and the water seal cavity are separated by a partition 13, and the horizontal main pipe 4 is connected to the left end of the transition cavity; the left end of the horizontal main pipe 4 is used to be connected to the drainage floor drain. Optionally, the drainage from the balconies on each floor of the residents is collected and discharged to the horizontal main pipe after passing through the floor drain with a water trap; the right end of the horizontal main pipe 4 is located in the transition cavity of the drainage cavity, and the upper side of the transition cavity is connected to the outside atmosphere.

[0044] A flow channel is provided in the transition chamber, and the flow channel is also communicated with the outside atmosphere; the left end of the flow channel is communicated with the right end of the horizontal main pipe; the right end of the flow channel is connected to the water seal chamber; and a water seal is provided in the water seal chamber.

[0045] Therefore, when the drainage from the balconies on each floor of the residents is collected and discharged to the horizontal main pipe after passing through the floor drain, the drainage enters the transition chamber and then enters the flow channel. Since the transition chamber and the flow channel are connected to the outside atmosphere, the "double water seal" problem can be solved, that is, the air resistance phenomenon is avoided; and the flow channel is connected to the water seal chamber, and the drainage enters the water seal chamber through the flow channel and is then discharged to the drainage treatment area for treatment.

[0046] Therefore, a drainage water seal device in an embodiment of the present invention solves the problem of double water seals, which causes poor drainage and drainage noise due to the air resistance phenomenon, through a drainage cavity, a transition cavity, a water inlet and a flow channel, and avoids the defects of setting up inspection wells and water seal wells, which result in many construction pipelines and great construction difficulty.

[0047] Furthermore, the drainage cavity is a cylindrical structure; the drainage cavity is made of plastic material.

[0048] Optionally, the drainage cavity is a cylindrical structure made of plastic material. In order to facilitate the communication between the drainage cavity and the outside atmosphere, an inspection well cover 1 is provided at the upper end of the drainage cavity, and a vent hole is provided on the inspection well cover.

[0049] Furthermore, one end of the flow channel bottom plate is higher than the other end of the flow channel bottom plate.

[0050] In order to facilitate the flow channel to transport drainage into the water seal chamber, the flow channel is a flow channel, and the height of the left end of the flow channel bottom plate of the flow channel is higher than the height of the right end of the flow channel bottom plate, so that the drainage of the horizontal main pipe flows to the right and into the water seal chamber.

[0051] An inspection well cover 1 is provided at one end of the drainage cavity; the drainage cavity is connected to the outside atmosphere through the inspection well cover; the other end of the drainage cavity is connected to the foundation 7.

[0052] Optionally, the bottom end of the drainage cavity is fixed on the foundation 7, thereby facilitating the stability of the drainage cavity.

[0053] In order to facilitate the discharge of drainage entering the flow trough, the water seal chamber is further provided with: a water seal chamber inlet pipe 10, which is provided in the water seal chamber 12, one end of the water seal chamber inlet pipe is connected to the other end of the flow trough, and the other end is sealed with a water seal in the water seal chamber; and a water seal chamber outlet pipe 11, which is provided in the water seal chamber, one end of the water seal chamber outlet pipe is sealed with a water seal in the water seal chamber, and the other end is connected to the external drainage pipe.

[0054] refer to Figure 1 As shown, the right end of the flow channel is connected to the water inlet pipe of the water seal chamber; the drainage enters the water inlet pipe of the water seal chamber through the flow channel, and then enters the water seal chamber through the lower end of the water inlet pipe of the water seal chamber; the drainage enters the water seal chamber to form a water seal, and the water seal seals the lower end of the water outlet pipe of the water seal chamber and the lower end of the water inlet pipe of the water seal chamber; the other end of the water inlet pipe of the water seal chamber is connected to the external drainage pipe.

[0055] Thereby, the lower end of the water inlet pipe of the water seal chamber and the lower end of the water outlet pipe of the water seal chamber can be sealed, thereby achieving the purpose of guiding the drainage to the external drainage pipe.

[0056] Furthermore, a filter 6 is provided at one end of the water inlet pipe of the water seal chamber.

[0057] To prevent clogging of the water seal chamber inlet pipe, the right end of the notch is connected to the right end of the water seal chamber inlet pipe through a filter, thereby preventing suspended matter such as sludge and garbage in the drainage from entering the water seal chamber inlet pipe. Optionally, the filter is a coarse screen; the coarse screen can remove some larger suspended matter and prevent clogging of the water seal chamber inlet.

[0058] Furthermore, the transition chamber and the water seal chamber are both provided with a water supply interface 8.

[0059] To prevent the water level in the transition chamber and the water seal chamber from being too low, both are provided with a water replenishment interface 8. The water replenishment interface on the side wall of the water seal chamber can be connected to a separate washbasin domestic wastewater drainage or a basement car ramp, a domestic water pump room pressure wastewater drainage, etc., to prevent the water seal from drying up.

[0060] Furthermore, the water seal chamber water inlet pipe 10 is a ┑-shaped water-flowing tee; the water seal chamber water outlet pipe 11 is a ┏-shaped water-flowing tee; the lower end of the water seal chamber water inlet pipe is connected to the lower end of the water seal chamber water outlet pipe through a water seal.

[0061] After the drainage enters the water seal, a water seal is formed through the inverted L-shaped inlet and outlet pipes (i.e. the ┑-shaped water-following tee and the ┏-shaped water-following tee), which can effectively prevent toxic and harmful gases in the subsequent outdoor drainage pipes from returning to the room.

[0062] The left opening of the ┑-shaped water-following tee is connected with the right end opening of the flow channel; the drainage flows obliquely from the flow channel into the left opening of the ┑-shaped water-following tee and enters the water seal, becoming a part of the water seal; then the water seal enters the ┏-shaped water-following tee through the lower opening of the ┏-shaped water-following tee, and the right opening of the ┏-shaped water-following tee is connected with the outdoor drainage pipe, thereby discharging the drainage entering the water seal.

[0063] Furthermore, a knob-type inspection port 9 is provided on both the water seal chamber water inlet pipe and the water seal chamber water outlet pipe.

[0064] Therefore, the water inlet pipe and the water outlet pipe of the water seal chamber can be inspected through the knob-type inspection port 9.

[0065] Therefore, the drainage water seal device of the embodiment of the present invention adopts an improved water seal device for balcony drainage, which combines a transition and a water seal in one structure. On the one hand, it solves the double water seal problem of the balcony drainage system, and on the other hand, it can prevent toxic and harmful gases from the outdoor drainage pipe from entering the room, and can also reduce the number of structures such as ground inspection wells.

[0066] Drainage from each floor's balcony flows through floor drains and then into a horizontal main pipe. The drainage then flows into a transition zone, which is open to the atmosphere, eliminating the "double water seal" problem. A coarse screen is installed at the front of the water seal's inlet pipe to remove some large suspended solids and prevent clogging of the seal. Once entering the seal, the inverted L-shaped inlet and outlet pipes create a water seal, effectively blocking toxic and harmful gases from subsequent outdoor drainage pipes. A water fill port on the water seal's wall can be connected to separate domestic wastewater drainage from washbasins, basement ramps, and pressure wastewater from pump rooms, preventing the seal from drying out. The entire drainage water seal system requires no electrical equipment or complex mechanical structures. All inlet and outlet pipes are factory-matched to the cylinder, making on-site installation quick and easy, and subsequent operation and maintenance are extremely simple. This system serves as a valuable demonstration for improving wastewater collection capacity and addressing internal odor overflows, and its practicality is highly marketable.

[0067] The embodiments of the present invention can directly serve urban renewal, new residential construction and other construction projects. The results are expected to have broad application prospects, and the environmental, social and economic benefits are significant. It is conducive to strengthening the prevention and control of water pollution at the source of residential buildings, providing better residential quality, and promoting the development of water environment governance in depth, at the source, and at the root, so as to contribute to building a strong ecological barrier for the Yangtze River.

[0068] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
