Technical Field

[0001] This utility model relates to the field of water supply device technology, specifically an automatic water supply device based on water level detection. Background Technology

[0002] For some domestic water tanks, the water supply valves are manually operated on a regular schedule. Each operation takes too long, making the existing water supply method inconvenient. It requires personnel to observe the water level and close the valve in time, which not only wastes labor costs but also consumes operation time. Furthermore, it is easy to delay water supply if the water supply cycle is not accurately grasped. Some automatic water supply methods use float switches, but the float is prone to getting stuck, leading to misjudgment. Therefore, we propose an automatic water supply device based on water level detection. Utility Model Content

[0025] Example 1

[0026] Please see Figures 1-5 As shown, this utility model provides a technical solution: an automatic water supply device based on water level detection, comprising:

[0027] The pool body 1 has a pool opening 101 at its top. An installation frame 103 is fixedly installed on the inner wall of the pool opening 101. An ultrasonic sensor 104 is fixedly installed at one end of the installation frame 103.

[0028] Water supply pipe 2, one end of water supply pipe 2 is connected to the bottom of pool body 1, and the other end of water supply pipe 2 is equipped with electric valve body 201;

[0029] The electrical control box 3 is electrically connected to the electric valve body 201 and the ultrasonic sensor 104 via wires. A manual control panel 4 is fixedly installed on the front of the electrical control box 3.

[0030] The upper part of the manual control panel 4 is equipped with a power indicator light 401, a valve open indicator light 402 and a valve close indicator light 403, and the lower part of the manual control panel 4 is equipped with a stop button 404, a start button 405 and a switch 406. The manual control panel 4 and the electrical control box 3 are electrically connected by wires.

[0031] This technical solution: After the ultrasonic sensor 104 is correctly installed using the mounting bracket 103 (powered by mains electricity), the ultrasonic sensor 104 can detect the water level in real time and synchronously transmit the detected signal to the control box 3. When the water level in the pool 1 reaches 4.9m (set high level), the control system in the control box 3 automatically triggers and closes the electric valve 201 to stop water supply. When the water level in the pool 1 is lower than 3.5m (set low level), the control system in the control box 3 automatically triggers and opens the electric valve 201 to add water (its working circuit is as follows). Figure 5 As shown, this device enables automatic water filling based on water level detection. It is simple to design and easy to operate, shortens water filling time, improves work efficiency, and saves labor costs. Through the setting of the manual control panel 4, it can bypass automatic control and switch to manual control when the control system is out of control. When the sensor or control circuit fails and the automatic control fails, the operator can directly control the electric valve body 201 to work through the manual switch button to avoid water level exceeding the limit. Manual operation can serve as the last line of defense to prevent water from overflowing in time. This gives the device the ability of ultrasonic sensor 104 plus manual redundant control, ensuring the normal use of the device.

[0032] Example 2

[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a protective cover 102 is provided at the upper end of the pool opening 101.

[0034] This technical solution: By setting up the protective cover 102, it can block the water inlet 101 above the pool, thus preventing foreign objects from entering the pool body 1.

[0035] Example 3

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the number of ultrasonic sensors 104 is two.

[0037] This technical solution: By using two ultrasonic sensors 104, the device has the redundancy of sensors, and by adding cross-verification of the two ultrasonic sensors 104, such as by installing two probes, taking the average value or setting the logic "AND / OR" judgment, the loss of control caused by the mismeasurement of a single sensor can be reduced.

[0038] Example 4

[0039] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, an audible and visual alarm 5 is fixedly installed on the top of the electrical control box 3, and the audible and visual alarm 5 is electrically connected to the electrical control box 3 via a wire.

[0040] This technical solution involves setting warning values ​​in the control program using the audible and visual alarm 5, such as a high warning value of 4.8m and a low warning value of 3.6m, and alarm values, such as a high alarm value of 4.9m and a low alarm value of 3.5m. When the water level is ≥4.8m or ≤3.6m, a warning signal is triggered, such as a flashing yellow LED light and a low-frequency buzzer. When the water level is ≥4.9m or ≤3.5m, an emergency alarm signal is triggered, such as a flashing red LED light and a high-frequency siren. This allows for timely warnings to team members, facilitating prompt manual intervention.

[0041] It should be noted that the audible and visual alarm 5 can be purchased directly from the market, and its connection method and electrical connection relationship adopt mature and conventional methods in existing technology, so they will not be described in detail here.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
