Description
Technical Field
[0001] This utility model belongs to the field of water drainage technology, and more specifically, it relates to a water drainage system. Background Technology
[0002] Currently, flood control relies on a manual, on-the-spot approach, using water pumps for drainage. This manual approach increases labor intensity and makes timely drainage impossible, while the use of water pumps is energy-intensive.
[0003] Another existing technology, entitled "A Drainage System for Reducing Road Flooding" with publication number CN115874698A, relates to a drainage system for reducing road flooding. This system includes: a drainage ditch fixedly buried in the foundation; a filter cover hinged to the drainage ditch, with locking components for fixing the cover; a garbage collection box located on the side wall of the drainage ditch, with an installation hole communicating with the garbage collection box in the ditch; a shield hinged to the bottom wall of the installation hole to cover it; a fixing assembly for fixing the shield between the shield and the drainage ditch; a filter screen inclined within the drainage ditch; a garbage flow channel inclined between the shield and the garbage collection box; and a water storage tank, with a first inlet communicating with the water storage tank in the drainage ditch and a second inlet communicating with the water storage tank in the garbage collection box. In this application, a filter screen is used to filter garbage from accumulated water into a garbage collection box, thereby effectively improving the problem of drainage ditch blockage caused by debris accumulation. This technology does not address the issues and solutions of this application. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a water collection and drainage system that can automatically monitor and drain water from a water collection tank, achieve unattended operation, eliminate manual labor, reduce the labor intensity of drainage, and achieve energy saving and cost reduction, in order to address the shortcomings of the existing technology.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] This utility model is a water drainage system. The main container is equipped with an inlet pipe and a check valve. The main container is also connected to a suction pipe and a drain pipe. The suction pipe is connected to a bottom anti-clogging filter screen. A pressurizing component is installed on the drain pipe. The bottom anti-clogging filter screen extends to the bottom of the water tank. A monitoring camera is installed above the water tank.
[0007] An inlet solenoid valve is installed on the water inlet pipe, and a liquid level sensor is installed inside the main container.
[0008] A drain outlet solenoid valve is installed on the drain pipe, and the drain outlet solenoid valve is located between the pressurization component and the drain outlet.
[0009] The water suction pipe is equipped with a water suction port solenoid valve.
[0010] A light is installed above the water collection pool.
[0011] The inlet solenoid valve and the outlet solenoid valve are respectively connected to the controller via signal transmission lines.
[0012] The monitoring camera is connected to the controller via a signal transmission line, and the liquid level sensor is also connected to the controller via a signal transmission line.
[0013] The lighting fixture is connected to the controller via a wire.
[0014] The water inlet pipe and check valve are located at the top of the main container.
[0015] The water suction pipe is located on the side of the main container near the lower part, and the drain pipe is located at the bottom of the main container.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] The water drainage system of this utility model includes an inlet pipe and a check valve on the main container. The inlet pipe allows water to enter the main container, while the check valve allows air to escape from the main container in one direction, preventing air from flowing back into the main container. The main container is also connected to a suction pipe and a drain pipe. The suction pipe draws water into the main container, and the drain pipe drains the water. A bottom anti-clogging filter filters the water before it is drawn into the main container, preventing impurities from entering. A pressurizing component compresses the air within it as the water level rises, creating overpressure. The bottom anti-clogging filter extends to the bottom of the water tank. A monitoring camera monitors and identifies the water tank in real time. Specifically, the camera identifies the water tank; when the water level exceeds a target value, a command is sent to close the suction pipe and simultaneously open the inlet, filling the main container with water for 1-2 minutes before stopping the filling. As the water level in the main container rises, the air inside is discharged to the outside of the main container through the check valve. The main container and the pressurizing component are connected. As the water level inside the main container rises, the air inside the pressurizing component is compressed to create overpressure. When the water level inside the main container reaches the level sensor position, a signal is triggered, the inlet pipe disconnects, and the drain pipe and suction pipe open simultaneously. As the water level inside the main container drops, a negative pressure is created inside the main container. Under the action of atmospheric pressure, the water in the sump is drawn in through the bottom suction anti-clogging filter, creating a siphon effect and draining the sump. This continues until the water in the sump is completely drained. When the sump exceeds the target value again, a command is sent to close the suction pipe and open the inlet, injecting water into the main container for 1-2 minutes before stopping. This process is then repeated to drain the sump again. This eliminates the need for manual operation, effectively achieving automatic monitoring and drainage of the sump water level, improving the reliability of monitoring and drainage, and reducing labor intensity.

Detailed Implementation
[0021] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0022] As attached Figure 1 As shown, this utility model is a water drainage system. The main container 9 is equipped with an inlet pipe and a check valve 2. The main container 9 is also connected to a suction pipe 14 and a drain pipe 6. The suction pipe is connected to a bottom anti-clogging filter screen 8, and a pressurizing component 11 is installed on the drain pipe. The bottom anti-clogging filter screen 8 extends to the bottom of the water tank, and a monitoring camera 5 is installed above the water tank. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structural configuration, the inlet pipe and check valve 2 on the main container allow water to enter the main container 9. The check valve 2 allows gas to be discharged unidirectionally from the main container 9, preventing air from flowing back into the main container. The main container 9 is also connected to a suction pipe 14 and a drain pipe 6. The suction pipe 14 draws water into the main container, and the drain pipe 6 discharges the water. The bottom anti-clogging filter screen 8 filters the water from the water tank before it is drawn into the main container, preventing impurities from entering. The pressurizing component 11 compresses the air within it as the water level rises, creating overpressure air. The bottom anti-clogging filter 8 extends to the bottom of the sump, and the monitoring camera 5 is used to monitor and identify the sump in real time. Specifically, the camera 5 identifies the sump, and when the water level exceeds a target value, a command is sent to close the suction pipe and simultaneously open the inlet to fill the main container with water for 1-2 minutes before stopping the filling. As the water level in the main container rises, the air inside the main container is discharged to the outside through the check valve. The main container 9 is connected to the pressurization component 11. As the water level inside the main container 9 rises, the air inside the pressurization component 11 is compressed to form overpressure air. When the water level inside the main container 9 reaches the position of the level sensor 3, a signal is triggered, the inlet pipe is disconnected, and the drain pipe 6 and suction pipe 4 are opened simultaneously. As the water level inside the main container 9 drops, a negative pressure is formed inside the main container 9. Under the action of atmospheric pressure, the water from the sump is drawn in through the bottom anti-clogging filter 8, forming a siphon effect and draining the sump. This continues until all the water in the sump is drained. When the water level in the sump exceeds the target value again, a command is sent to close the suction pipe and simultaneously open the inlet to fill the main container 9 with water for 1-2 minutes before stopping. This process is then repeated to drain the water again. This eliminates the need for manual operation, effectively achieving automatic monitoring and drainage of the sump water level, improving the reliability of monitoring and drainage, and reducing labor intensity. The water drainage system described in this invention enables automatic monitoring and drainage of the sump water, achieving unattended operation, eliminating manual labor, reducing labor intensity, and achieving energy conservation and cost reduction.
[0023] An inlet solenoid valve 1 is installed on the inlet pipe, and a liquid level sensor 3 is installed inside the main container 9. In this structure, the liquid level sensor 3 is used for liquid level monitoring. When the water level inside the main container 9 reaches the position of the liquid level sensor 3, a signal is triggered, and the signal is transmitted to the control component 10 through the signal transmission line 13. The control component 10 then issues a command to close the inlet solenoid valve 1.
[0024] A drain outlet solenoid valve 12 is installed on the drain pipe, located between the pressurization component 11 and the drain outlet. In this structure, the pressurization component 11 is a tank that allows air to enter and be compressed. The drain outlet solenoid valve 12 can be controlled on and off by the control component 10, thus fulfilling the function of draining accumulated water on site.
[0025] A water intake solenoid valve 4 is installed on the water intake pipe. With the above structure, the water intake solenoid valve 4 can be controlled on and off by the control component 10, fulfilling the function of on-site water drainage.
[0026] A lighting lamp 7 is installed above the water accumulation tank. In this structure, the lighting lamp is used for on-site illumination, ensuring that the monitoring camera can accurately obtain information about the water level in the water accumulation tank.
[0027] The control component (controller) is a microcontroller, such as the STM32H743VIT6. Microcontrollers are a mature technology in the field of electronics, and the control component of this invention is a direct application of existing mature technology, not an improvement.
[0028] The inlet solenoid valve 1 and the outlet solenoid valve 12 are connected to the controller 10 via signal transmission lines 13. The monitoring camera 5 and the liquid level sensor 3 are also connected to the controller 10 via signal transmission lines 13. The lighting lamp 7 is connected to the controller 10 via wires 15. In this structure, different components are connected to the controller, which controls the start and stop of the relevant components to ensure overall functionality.
[0029] The inlet pipe and check valve 2 are located at the top of the main container 9. In this structure, the inlet pipe connects to the water supply tank and is used for water intake when the inlet solenoid valve 1 is opened. The check valve 2, located at the top of the main container 9, is used for venting air from the upper part of the container.
[0030] The suction pipe 14 is located on the side of the main container 9 near the lower part, and the drain pipe 6 is located at the bottom of the main container 9. This structure allows drainage from the bottom.
[0031] The control principle and process of a specific embodiment of this utility model are as follows: The controller 10 monitors the water accumulation pit in real time through the monitoring camera 9. When the water accumulation in the pit exceeds the target value, the controller sends a command through the signal transmission line 13 to close the suction port solenoid valve 4, and simultaneously opens the inlet solenoid valve 1 to inject water into the main container 9 for 1-2 minutes, after which it commands to close the drain port solenoid valve 12. As the water level in the main container 9 rises, the air inside the main container 9 is discharged unidirectionally from the main container 9 through the check valve 2, while preventing air from flowing back into the main container 9. As the water level in the main container 9 rises, the air in the pressurization component 11 is compressed to form overpressure air. When the water level in the main container 9 reaches the level sensor 3, a signal is triggered, and the signal is transmitted to the controller 10 through the signal transmission line 13. The controller 10 sends a command to close the inlet solenoid valve 1, and simultaneously opens the drain port solenoid valve 12 and the suction port solenoid valve 4. As the water level in the main container 9 drops, a negative pressure is created inside the main container 9. Under the action of atmospheric pressure, the accumulated water is drawn in from the bottom suction anti-clogging filter screen 8, forming a siphon effect to drain the water in the sump until the water level is lower than the bottom suction anti-clogging filter screen 8.
[0032] The water drainage system of this utility model is structurally designed with an inlet pipe and a check valve 2 on the main container. The inlet pipe is used to introduce water into the main container 9, and the check valve 2 is used to discharge gas from the main container 9 in one direction to prevent air from flowing back into the main container 9. The main container 9 is also connected to a suction pipe 14 and a drain pipe 6. The suction pipe 14 is used to draw water into the main container, and the drain pipe 6 is used to discharge the water. A bottom anti-clogging filter 8 is used to filter the water from the sump before it is drawn into the main container 9, preventing impurities from entering. A pressurizing component 11 is used to compress the air inside the pressurizing component to create overpressure air as the water level rises. The bottom anti-clogging filter 8 extends to the bottom of the sump. A monitoring camera 5 is used to monitor and identify the sump in real time. Specifically, the camera identifies the sump; when the water level exceeds a target value, a command is sent to close the suction pipe and simultaneously open the inlet to inject water into the main container for 1-2 minutes before stopping the injection. As the water level in the main container 9 rises, the air inside the main container 9 is discharged one-way to the outside of the main container 9 through the check valve 2. The main container 9 is connected to the pressurization component 11. As the water level inside the main container 9 rises, the air inside the pressurization component 11 is compressed to form overpressure air. When the water level inside the main container 9 reaches the position of the liquid level sensor 3, a signal is triggered, the inlet pipe is disconnected, and the drain pipe 6 and the suction pipe 4 are opened simultaneously. As the water level inside the main container 9 drops, a negative pressure is formed inside the main container 9. Under the action of atmospheric pressure, the water in the sump is drawn in from the bottom suction anti-clogging filter 8, forming a siphon effect and realizing the drainage of the sump. This continues until the water in the sump is completely drained. When the sump exceeds the target value again, a command is sent again to close the suction pipe and open the inlet to inject water into the main container 9 for 1-2 minutes, then stop injecting water, and then repeat the following steps to achieve drainage again. In this way, no manual operation is required, realizing automatic monitoring and automatic drainage of the water level in the sump, improving the reliability of monitoring and drainage, and reducing labor intensity by eliminating the need for manual operation.
