Description

Technical Field

[0001] This utility model relates to the technical field of water supply and drainage systems, and in particular to a rainwater and sewage separation device. Background Technology

[0002] Urban water supply and drainage systems require the management of rainwater collection, storage, utilization, and discharge. Rainwater wells are ubiquitous in urban roads, used to collect and discharge rainwater. Typically, rainwater wells have holes on their inner sides that connect to drainage pipes, and a downward-extending seepage pipe at the bottom to replenish rainwater underground and allow excess rainwater to be discharged through the drainage pipes.

[0003] However, drainage pipes are usually connected to sewage pipe systems. When rainfall is excessive, a large amount of rainwater flows into the sewage system through the drainage pipes, which can easily cause sewage backflow and overflow, resulting in sewage pollution in residential areas and posing a significant public health hazard. Utility Model Content

[0004] The purpose of this invention is to provide a rainwater and sewage separation device, which has the advantage of automatically separating and isolating the rainwater system and the sewage system, and can prevent sewage backflow.

The solar energy module includes a control box, a solar panel, a water collection tank, and a rain sensor; the control box is suspended above the side of the rainwater well, and a control board and a rechargeable battery are installed inside the control box; the solar panel is tilted and installed in front of the control box, the water collection tank is horizontally installed in front of the bottom edge of the solar panel, and the rain sensor is installed in the middle of the top surface of the water collection tank; The solar panel is used to charge the rechargeable battery when the weather is sunny. The rechargeable battery is used to power the control board, electric valve and rain sensor. The control board is used to receive the signal from the rain sensor and control the opening and closing of the electric valve.

[0006] Furthermore, the control box for the solar panel is mounted on the top of a pole erected on one side of the rainwater well.

[0007] Furthermore, the pole has a wiring channel inside, and a pre-embedded pipe is installed in the ground at the bottom of the pole; the wiring channel and the pre-embedded pipe of the pole are interconnected with the inner wall of the rainwater well, and an electrical connection wire is run through the wiring channel and the pre-embedded pipe, which is connected to the solar panel and the valve assembly.

[0008] Furthermore, the electric valve includes a valve seat, a valve core, and a motor; the lower part of the valve seat has a horizontally penetrating through-hole, and the upper part of the valve seat has a movable groove that connects downward to the through-hole; the top of the valve seat has a movable hole that connects downward to the movable groove; the valve core includes a valve stem and a valve plate arranged vertically, the valve plate being able to move vertically and installed in the valve seat, the valve stem extending upward out of the movable hole and connected to the motor located above the valve seat; the motor drives the valve stem to move vertically and drives the valve plate to reciprocate between the lower and upper parts of the valve seat through the opening and closing through-hole.

A motor housing is provided on the top of the filter housing, and the motor is installed in a waterproof and sealed manner inside the motor housing.

[0012] By adopting the above technical solution, the rainwater and sewage separation device of this utility model can be used to upgrade existing rainwater wells and automatically control whether the rainwater wells are connected to drainage pipes based on whether it is raining, so as to solve existing public health and safety hazards.

[0013] Using a connecting flange, the electric valve can be stably installed on the drainage pipe of the existing rainwater well sidewall. By covering it with a filter housing, the electric valve can be prevented from being blocked by debris, thus ensuring its normal opening and closing. Normally, the electric valve remains open, allowing the water flowing into the rainwater well to flow through the drainage pipe, for example, to the sewage system, without affecting the normal drainage of the rainwater well. At the same time, by installing a rainwater sensor, it can detect whether it is raining. When rain is detected, the control panel can control the electric valve to close the drainage pipe, preventing a large amount of rainwater from flowing into the sewage system and preventing sewage backflow and overflow, thus ensuring public health and safety.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] like Figures 1 to 5 As shown, a rainwater and sewage separation device in this embodiment includes a valve assembly 10 and a solar panel 20.

[0018] The valve assembly 10 includes a filter housing 1, an electric valve 2, and a connecting flange 3; the electric valve 2 is connected to a drainage pipe 40 with an opening in the inner wall of the rainwater well 30 via the connecting flange 3; the filter housing 1 covers the outer periphery of the electric valve 2 and the connecting flange 3, and the side wall of the filter housing 1 is provided with filter mesh 11.

[0019] The solar panel 20 includes a control box 4, a solar panel 5, a water collection tank 6, and a rain sensor 7. The control box 4 is suspended above the side of the rainwater well 30 and contains a control board 41 and a rechargeable battery 42. The solar panel 5 is tilted in front of the control box 4, the water collection tank 6 is horizontally installed in front of the bottom edge of the solar panel 5, and the rain sensor 7 is installed in the middle of the top surface of the water collection tank 6. The water collection tank 6 can collect rainwater when it rains and can also receive rainwater flowing down from the solar panel 5, enabling the rain sensor 7 to more accurately detect whether it is raining.

[0020] The solar panel 5 is used to charge the rechargeable battery 42 when the weather is sunny, ensuring the continuous operation of the device; the rechargeable battery 42 is used to power the control board 41, the electric valve 2 and the rain sensor 7; the control board 41 is used to receive the signal from the rain sensor 7 and control the opening and closing of the electric valve 2 according to the program settings.

[0021] Therefore, the rainwater and sewage separation device of this embodiment can be used to upgrade existing rainwater wells 30. The electric valve 2 can be stably installed on the drainage pipe 40 on the side wall of the existing rainwater well 30 using the connecting flange 3 of the valve assembly 10. The filter housing 1 can prevent the electric valve 2 from being blocked by debris and affecting its normal opening and closing. Normally, the electric valve 2 is kept open, allowing the water flowing into the rainwater well 30 to flow through the drainage pipe 40, for example, to the sewage system, without affecting the normal drainage of the rainwater well 30. At the same time, by setting the rainwater sensor 7 of the solar panel 20, it can detect whether it is raining. When rain is detected, the control board 41 can control the electric valve 2 to close the drainage pipe 40, preventing a large amount of rainwater from flowing from the drainage pipe 40 into the sewage system, preventing sewage backflow and overflow, and ensuring public health and safety.

[0022] In this embodiment, the control box 4 of the solar panel 20 can be installed on the top of the pole 8 erected on one side of the rainwater well 30, which can facilitate the control of the installation angle of the solar panel 5. The pole 8 can have a wiring channel 81 inside, and a pre-embedded pipe 9 can be installed in the ground at the bottom of the pole 8. The wiring channel 81 of the pole 8 is interconnected with the inner wall of the rainwater well 30 through the pre-embedded pipe 9. Electrical connection wires 91 can be run through the wiring channel 81 and the pre-embedded pipe 9 to facilitate the electrical connection between the solar panel 20 and the valve assembly 10.

[0023] Of course, if there is a wall near the rainwater well 30, the control box 4 can also be wall-mounted directly.

[0024] In this embodiment, the electric valve 2 includes a valve seat 21, a valve core 22, and a motor 23.

[0025] The valve seat 21 has a horizontal through hole 211 at its lower part, and the side wall of the through hole 211 is also provided with a groove 212. The upper part of the valve seat 21 has a movable groove 213 that communicates downward with the through hole 211. The bottom of the valve seat 21 is provided with a support foot 214, and the top has a movable hole 215 that communicates downward with the movable groove 213. The valve core 22 includes a valve stem 221 and a valve plate 222 arranged vertically. The valve plate 222 is installed in the valve seat 21 and can move vertically. The valve stem 221 extends upward through the movable hole 215 and is connected to a motor 23 located above the valve seat 21. The motor 23 drives the valve stem 221 to move up and down and drives the valve plate 222 to move back and forth between the lower and upper parts of the valve seat 21.

[0026] When the valve plate 222 moves down, it enters the lower part of the valve seat 21 and its edge is embedded in the groove 212 to block the through hole 211. When the valve plate 222 moves up, it enters the movable groove 213 in the upper part of the valve seat 21 to open the through hole 211, thereby realizing the opening and closing operation of the electric valve 2.

[0027] The valve seat 21 is provided with a support foot 214 at the bottom, which can provide stable support for the valve seat 21 and ensure the normal movement of the valve core 22.

[0028] In this embodiment, the connecting flange 3 includes a front flange 31 and a rear flange 32. The front flange 31 and the rear flange 32 are respectively locked to the valve seat 21 on both sides, and the rear side of the rear flange 32 is connected and fixed to the drainage pipe 40.

[0029] In this embodiment, the filter housing 1 is a cylindrical shape with an open bottom, and covers the valve seat 21, valve core 22 and connecting flange 3 of the electric valve 2 from top to bottom. The side of the filter housing 1 is provided with a notch 12 to accommodate the drain pipe 40, and the top of the filter housing 1 is provided with a clearance hole 13 to accommodate the valve stem 221.

[0030] In this embodiment, the filter housing 1 is mainly covered around the valve seat 21 and the valve core 22. A motor housing 14 can be provided on the top of the filter housing 1. The motor 23 is installed inside the motor housing 14, and the motor 23 can be individually waterproofed and sealed for protection.

[0031] Of course, the filter housing 1 can also be completely covered and surrounded by the valve seat 21, valve core 22 and motor 23, and is not limited to this embodiment.
