Specific embodiments

[0030] The following will further elaborate on the present utility model in conjunction with the drawings.

[0031] Embodiment: Refer to Figure 1 - Figure 5 A warning device for sewage pipe network monitoring disclosed by the present utility model includes:

[0032] The control housing 1 is arranged at the well wall of the inlet well of the sewage pipe network. A control unit is arranged inside the control housing 1. The control unit is composed of a circuit board, a main control chip, a signal preprocessing and conversion module, an output driving circuit, a power management module, and a communication interface. The top of the control housing 1 extends upward with an ejector rod 2, and an alarm assembly 3 is arranged at the top of the ejector rod 2;

[0033] The downward pipe 4 is arranged at the bottom end of the control housing 1. A sliding pipe 5 is slidably arranged at the lower end of the downward pipe 4. A sealing plate 6 is arranged at the bottom end of the sliding pipe 5. A detection assembly 7 for monitoring water quality is arranged at the bottom end of the sealing plate 6. An annular floating cylinder 8 is arranged at the bottom end of the outer peripheral wall of the sliding pipe 5. A wire assembly 9 for connecting the detection assembly 7 and the control unit is arranged inside the downward pipe 4 and the sliding pipe 5.

[0034] In this embodiment, as Figure 1 shown, the control housing 1 is installed at the top end of the well wall of the inlet well of the sewage pipe network. Through the downward pipe 4 and the sliding pipe 5, the detection assembly 7 is inserted downward into the sewage. And through the arrangement of the annular floating cylinder 8, a supporting force is provided for the sliding pipe 5, so that the sliding pipe 5 can be inserted into the sewage only with the detection assembly 7 at the bottom end under the influence of the buoyancy of the annular floating cylinder 8. Therefore, when the water level of the sewage changes, the position of the detection assembly 7 in the sewage can be always maintained to realize the monitoring of the sewage.

[0035] The data measured by the detection assembly 7 is formed into an electrical signal and transmitted to the information preprocessing and conversion module. During the monitoring process, if the change speeds of the water flow velocity, pressure and water quality pollution in the sewage exceed the threshold value, the information preprocessing and conversion module outputs the information to the alarm assembly 3. Then, a buzzer sound is generated through the alarm assembly 3 and transmitted to the corresponding department through the network to achieve the purpose of monitoring and early warning of the sewage pipe network.

[0036] In a further preferred embodiment of the present utility model, as Figure 5 shown, the alarm assembly 3 includes:

[0037] A housing part 31, which is fixedly arranged at the top of the top rod 2. A wireless signal transmission unit 32 is arranged at the bottom end inside the housing part 31. An alarm buzzer 33 is arranged at the top end inside the housing part 31. Both the alarm buzzer 33 and the wireless signal transmission unit 32 are installed on the circuit board arranged inside the housing part 31.

[0038] In this embodiment, the housing part 31 is fixedly connected to the top end of the top rod 2. When the information preprocessing and conversion module outputs the information to the alarm assembly 3, the alarm signal is first received through the wireless signal transmission and conversion unit, and the information is transmitted to the relevant department through the Internet of Things. At the same time, the alarm buzzer 33 is activated to generate a buzzer sound.

[0039] In a further preferred embodiment of the present utility model, as Figure 3 shown, the wire assembly 9 includes:

[0040] A telescopic rod 91, which is arranged inside the downward pipe 4. The outer cylinder of the telescopic rod 91 is fixedly connected to the top end of the downward pipe 4. The inner cylinder of the telescopic rod 91 is slidably arranged at the bottom end inside the outer cylinder, and the bottom end of the inner cylinder is fixedly connected to the sliding pipe 5.

[0041] A helical wire 92 is wound around the outer peripheral wall of the telescopic rod 91, and both ends of the helical wire 92 are respectively connected to the control unit and the detection component 7.

[0042] In this embodiment, as Figure 3 shown, the telescopic rod 91 is provided to guide the helical wire 92, so that the helical wire 92 is wound around the outer peripheral wall of the telescopic rod 91, and there is a large gap between the skin of the helical wire 92 and the outer wall of the telescopic rod 91. Therefore, when the sliding tube 5 slides downward, it can be naturally stretched to adapt to the lengths of the downward tube 4 and the sliding tube 5, so as to facilitate the storage of the helical wire 92, and further facilitate the detection component 7 to transmit the measured signal to the control unit through the helical wire 92.

[0043] In a further preferred embodiment of the present utility model, as Figure 4 shown, the detection component 7 includes:

[0044] A protection cylinder 71 is arranged at the bottom end of the sealing plate 6, and a rotating cavity 72 is formed in the side wall of the protection cylinder 71;

[0045] An isolation cylinder 73 is arranged inside the rotating cavity 72. Installation shafts 74 are arranged at both ends of the isolation cylinder 73, and the installation shafts 74 are inserted into the inner wall of the rotating cavity 72. A plurality of uniformly distributed blades 75 are arranged on the outer peripheral wall of the isolation cylinder 73, and a plurality of water inlet holes 76 are formed at positions between two adjacent blades 75 on the outer peripheral wall of the isolation cylinder 73;

[0046] A detection element is located inside the isolation cylinder 73 and is fixedly connected to the isolation cylinder 73.

[0047] In this embodiment, when the sewage flows, it will push the blades 75 to move and cause the isolation cylinder 73 to rotate. During the rotation of the isolation cylinder 73, the positions of the water inlet holes 76 in the same direction as the sewage flow are constantly changing, which can effectively prevent the solid matter in the sewage from sticking to the water inlet, and can achieve the effect of preventing sewage from entering.

[0048] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, a photovoltaic power supply panel 10 is hinged to the side wall of the housing part 31, and a battery element connected to the photovoltaic power supply panel 10 is arranged inside the control housing 1 for supplying power to the control unit, the alarm component 3 and the detection component 7.

[0049] In this embodiment, the photovoltaic power supply panel 10 and the battery element supply power to the control unit, the alarm component 3 and the detection component 7.

[0050] The implementation principle of the above embodiments is as follows: After installation, the sliding tube 5 can freely fall under the influence of gravity until the annular float 8 contacts the water surface of the sewage. At this time, the detection component 7 at the bottom end can be inserted into the sewage. When the water level of the sewage changes, the position of the detection component 7 in the sewage can be always maintained to reduce the detection data difference formed by the change between the detection component and the water level.

[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
