Description

Technical Field

[0001] The utility model relates to the technical field of rain and sewage pipe networks, in particular to an abnormal detection device for urban rain and sewage pipe networks. Background Technique

[0002] With the acceleration of the urbanization process, as an important part of urban infrastructure, the stability and operation efficiency of the urban drainage system are directly related to the daily operation of the city and the quality of life of residents. However, due to factors such as long-term use, lack of regular maintenance, and unreasonable planning, various abnormal conditions often occur in urban rain and sewage pipe networks, such as blockage, damage, leakage, and sewage overflow. These problems not only affect the normal operation of the urban drainage system but also may cause serious impacts on the environment and residents' lives. Therefore, it is particularly important to develop an efficient abnormal detection device for urban rain and sewage pipe networks.

[0003] Based on the above reasons, this design proposes an abnormal detection device for urban rain and sewage pipe networks. Summary of the Invention

[0004] The purpose of the utility model is to provide an abnormal detection device for urban rain and sewage pipe networks.

[0005] To achieve the above purpose, the utility model is realized by such a technical solution. An abnormal detection device for urban rain and sewage pipe networks includes a rain and sewage pipe. A detection manhole cover is covered on the upper end of the rain and sewage pipe. The width of the detection manhole cover is greater than the width of the rain and sewage pipe. A nozzle is connected to the center of the detection manhole cover. The lower end of the nozzle is communicated with a telescopic guide rod. A spring is sleeved on the outer side wall of the telescopic guide rod. The upper end of the spring abuts against a pressure sensor, and the lower end of the spring abuts against the inside of a detection airbag. The detection airbag is clamped inward in a pincer shape. The detection airbag is communicated with the telescopic guide rod.

[0006] Further, solar panels are respectively arranged on the left and right sides of the detection manhole cover. The solar panels are connected to a battery and supply power to the air pump and the pressure sensor through the battery.

[0007] Further, light inlet holes are respectively arranged on the left and right sides of the detection manhole cover. The light inlet holes diverge to both sides.

[0008] The beneficial effects of the above solution are:

[0009] The utility model generates electricity through a solar panel by means of light passing through a light inlet hole for battery energy storage, and the battery 8 powers the air pump. Under normal circumstances, the telescopic guide rod extends under the action of gravity and the spring, so that the detection airbag is in a lower position. When congestion or other abnormal conditions cause the water level in the pipe network to rise abnormally, due to the buoyancy effect, the detection airbag causes the telescopic guide rod to contract and drive the detection airbag to float, resulting in a decrease in the reading of the pressure sensor and starting the air pump to inflate the detection airbag, thereby forcing the detection airbag to float further, causing the reading of the pressure sensor to further decrease and an alarm to be issued, so as to achieve the purpose of abnormal detection and monitoring.

[0013] The following further clearly and completely describes the present utility model in conjunction with the accompanying drawings of the specification, but the protection scope of the present utility model is not limited thereto. Embodiment

[0014] As Figures 1 to 2 shown, an abnormal detection device for urban rain and sewage pipe networks includes a rain and sewage pipe 1, the upper end of the rain and sewage pipe 1 is covered with an inspection well cover 2, the width of the inspection well cover 2 is greater than the width of the rain and sewage pipe 1, the center of the inspection well cover 2 is connected with an air nozzle 3, the air nozzle 3 is communicated with an air pump 9, the lower end of the air pump 9 is communicated with a telescopic guide rod 4, a spring 5 is sleeved on the outer side wall of the telescopic guide rod 4, the upper end of the spring 5 abuts against a pressure sensor 11, the lower end of the spring 5 abuts against the inside of a detection airbag 6, the detection airbag 6 is clamped inward in a pincer shape, and the detection airbag 6 is communicated with the telescopic guide rod 4.

[0015] In this embodiment, solar panels 7 are respectively arranged on the left and right sides of the inspection well cover 2, and the solar panels 7 are communicated with a battery 8 and supply power to the air pump 9 and the pressure sensor 11 through the battery 8.

[0016] In this embodiment, light inlet holes 10 are respectively arranged on the left and right sides of the inspection well cover 2, and the light inlet holes 10 are arranged to diverge to both sides.

[0017] Working principle:

[0018] Light passes through the light inlet hole 10 and uses the solar panel 7 to generate electricity for storage in the battery 8. The battery 8 powers the air pump 9. Under normal circumstances, the telescopic guide rod 4 extends under the action of gravity and the spring 5, causing the detection airbag 6 to be in a lower position. When there is congestion or other abnormal situations that cause the water level in the pipeline network to rise abnormally, due to the buoyancy effect, the detection airbag 6 causes the telescopic guide rod 4 to contract and drives the detection airbag 6 to float upward, causing the reading of the pressure sensor 11 to decrease, and starting the air pump 9 to inflate the detection airbag 6, thereby forcing the detection airbag 6 to float further upward, causing the reading of the pressure sensor 11 to further decrease and an alarm to be issued for the reading.

Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
