DETAILED DESCRIPTION

[0013] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1-4The present invention provides the following technical solutions: a water tank for storing and supplying secondary water, comprising a box body 1 and a secondary water inlet pipe 2, a tap water inlet pipe 3, a water supply pipe 4, and an overflow pipe 5 arranged on the box body 1; the secondary water inlet pipe 2 is arranged on the top plate of the box body 1, and is connected to the downpipe of the equipment on the upper floor that produces waste water for washing hands (washing, washing vegetables, etc.), and the secondary water inlet pipe 2 is provided with a switch 11 and a filtering and disinfecting device 12, which can filter and disinfect the waste water into clean water for storage and standby, and the filtering and disinfecting device 12 is removable. The modular structure is convenient for cleaning and replacing the disinfection component. The switch 11 can play two roles. First, when the waste water cannot be filtered and cleaned, the switch can be turned off to stop the water from entering the water tank, so that it is discharged into the municipal wastewater drainage system through the drain pipe 13. Second, when cleaning or replacing the filtering and disinfecting device 12, the switch 11 is turned off to prohibit the water from flowing out of the filtering and disinfecting device 12; the tap water inlet pipe 3 is connected to the tap water pipe, passes through the top plate of the box body 1 from top to bottom and enters the water tank. The outlet of the tap water inlet pipe 3 is close to the bottom plate of the box body 1, and its lower end is close to the bottom plate of the box body 1. A floating water shut-off valve 7 is provided near the water outlet. When the secondary water level in the water tank is higher than the position of the floating water shut-off valve 7, the water tank stores and supplies the secondary water. When the water level in the water tank drops below the position of the floating water shut-off valve 7, the floating water shut-off valve 7 drops and opens the tap water inlet pipe 3 to replenish the tap water into the water tank to make up for the shortage of the secondary water. When the water level in the water tank rises, the floating water shut-off valve 7 also moves upward with the buoyancy support of the rising water level. When it reaches a certain position, it closes the tap water inlet pipe 3 and stops replenishing the tap water into the water tank. The water supply pipe 4 is located at the lower corner of the box body 1, and is connected to the toilet (urinal) and other equipment to provide water for flushing; the overflow pipe 5 is located at the uppermost end of the side panel of the box body 1, and the overflow pipe 5 can be connected to the secondary water inlet pipe of such a water tank on the next floor through a pipeline. When the water level in the water tank exceeds the overflow pipe 5, it can be injected into the water tank on the next floor through the overflow pipe 5 and the secondary water inlet pipe of the next floor for storage and standby. The overflow pipe 5 can also be connected to the drain pipe. When the water level in the water tank exceeds the overflow pipe 5, it is directly discharged into the municipal wastewater drainage system through the drain pipe.

[0015] Furthermore, the water tank body 1 has two interfaces 8 for the secondary water inlet pipe 2 to be selectively connected and fixed, such as Figure 2 The interface 8 is located at the center of the edge of one end of the top plate of the box body 1. After the switch 11 and the filtering and disinfecting device 12 are installed, its port can reach a corner of the box body. Two interfaces are set for 2-choice-1, which can facilitate the secondary water inlet pipe 2 to follow the wall (or enter the wall) to connect to the sewer pipe of the equipment that generates secondary water on the upper floor when the box body 1 is installed against the wall. The interface is located at the edge of the top plate of the box body 1 so that the secondary water can enter the water tank along the side plate of the box body 1 to avoid noise that affects the work and rest of the personnel; the box body 1 has 4 interfaces 9 for the overflow pipe 5 to select and connect to, such as Figure 2The interface 9 is located at two adjacent corners of two sets of adjacent side panels, and 4 interfaces are set for 4-choice 1, which can facilitate the overflow pipe 5 to connect to the target water pipe along the wall (or enter the wall) when the box body 1 is installed against the wall anyway; the box body 1 has 6 interfaces 10 for the water supply pipe 4 to choose to connect and fix. Figure 3 The interface 10 is located at the three bottom corners with a common vertex under the box 1. Six interfaces are set for 6-choice-1, so that the water supply pipe 4 can be conveniently connected to the target water pipe along the wall (or into the wall) when the box 1 is installed against the wall. Each interface has an internal thread structure, which makes it convenient for each water pipe to be connected and fixed to the box through the top thread, and the remaining ones can be conveniently closed with threaded plugs when not in use.

[0016] Furthermore, a pressure relief pipe 6 is provided on the top plate of the box body 1. The top of the pressure relief pipe 6 is closed, and the upper two-thirds of the pipe body is densely covered with small holes. When multiple water tanks in a high-rise building are connected and used floor by floor, pressure can be released to avoid damage or bursting of the water tanks due to overpressure.

[0017] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in other combinations, modifications and environments, and can be modified within the scope of the conception of this article through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
