Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring, and more specifically to an intelligent manhole cover water level monitoring device with multiple float switches. Background Art

[0002] In industrial production and daily life, the monitoring and control of water levels are crucial. Existing water level monitoring devices mostly use a single float switch or ultrasonic, infrared and other monitoring devices. A single float switch can only monitor the liquid level at a fixed point under the manhole, while ultrasonic and infrared liquid level monitoring devices are affected by factors such as the installation location and the complex underground environment. The liquid level monitoring is inaccurate. The most important thing is that the project implementation cost is much higher than that of the float switch. In situations where multiple water level thresholds need to be monitored, a single float switch often cannot meet the requirements. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0017] Combination Figure 1-Figure 2 In this embodiment, the multi-float switch intelligent manhole cover water level monitoring device includes a stainless steel mounting bracket 4, on which a float switch is mounted, a junction box 5 is provided at the upper end of the stainless steel mounting bracket 4, and the junction box 5 is connected to an intelligent manhole cover monitor 6, which is connected to the float switch via the junction box 5.

[0018] In this embodiment, the interior of the stainless steel mounting bracket 4 is a hollow structure. The hollow structure design of the stainless steel mounting bracket 4 reduces water resistance and improves the response speed of the float. A fixing ear 41 is symmetrically welded on one side of the stainless steel mounting bracket 4. The fixing ear 41 is connected to the inner wall of the manhole by bolts, and the stainless steel mounting bracket 4 can be fixed by the fixing ear 41.

[0019] In this embodiment, the stainless steel mounting bracket 4 has switch fixing holes 42 equidistantly formed on one side away from the fixing ear 41 , and a float switch is installed on the switch fixing hole 42 . The float switch can adjust the distance between them according to installation requirements, and is flexible to use.

[0020] In this embodiment, the float switch includes a first switch 1, a second switch 2 and a third switch 3. The first switch 1, the second switch 2 and the third switch 3 are distributed from bottom to top along the stainless steel mounting bracket 4. When the water level rises, the first switch 1 works first.

[0021] In this embodiment, the smart manhole cover monitor 6 is installed under the manhole cover, and no less than three liquid level transmission signal wiring pins are arranged inside the smart manhole cover monitor 6, and the liquid level transmission signal wiring pins are connected to different float switches through the junction box 5. When the liquid level rises or falls, when the float rises or falls to a preset position, the float switch outputs a signal to the smart manhole cover monitor 6, which can be used for liquid level alarm, and the smart manhole cover monitor 6 communicates with the platform through 4G Cat 1 signal.

[0022] Working process: When the water level in the manhole is lower than the first switch 1, the smart manhole cover monitor 6 is in a normal dormant state. When the water level in the manhole reaches the first switch 1, the smart manhole cover monitor 6 is awakened and reads the states of the first switch 1, the second switch 2 and the third switch 3 one by one. When the smart manhole cover monitor 6 is reading the state, if the manhole water level is lower than the first switch, the smart manhole cover monitor 6 enters the dormant state again. When the smart manhole cover monitor 6 is reading the state, if the manhole water level is higher than the first switch 1 and lower than the second switch 2, the smart manhole cover monitor 6 sends the abnormal state of the first switch 1 to the management platform. When the smart manhole cover monitor 6 is reading the state, if the manhole water level is higher than the first switch 1 and lower than the second switch 2, the smart manhole cover monitor 6 sends the abnormal state of the first switch 1 to the management platform. If the water level is above the second switch 2 and lower than the third switch 3, the smart manhole cover monitor 6 sends the abnormal status of the first switch 1 and the second switch 2 to the management platform. When the monitoring device 6 reads the status, if the water level in the manhole is higher than the float switch 3, the monitoring device 6 sends the abnormal status of the first switch 1, the second switch 2 and the third switch 3 to the management platform. When the smart manhole cover monitor 6 sends abnormal data, if the water level does not change for a certain period of time, the smart manhole cover monitor 6 re-enters the sleep state. When the water level changes, the device wakes up again and repeats the above operation process. When the smart manhole cover monitor 6 sends abnormal data, the water level changes, and the smart manhole cover monitor 6 repeats the above operation process.

[0023] To sum up: the utility model is a multi-float switch intelligent manhole cover water level monitoring device, which is equipped with more than three float switches and can monitor multiple water level thresholds at the same time, thereby improving the flexibility and accuracy of monitoring. The float switch is arranged on a hollow stainless steel mounting bracket 4, which reduces water resistance and improves the response speed of the float. The waterproof design of the float switch makes it suitable for various environments and enhances the durability of the device. The float switch technology is mature, stable and low in cost, and is an ideal alternative to other liquid level meters.
