Description

Technical Field

[0001] This invention relates to the field of inspection well technology, and more specifically to an inspection well fall monitoring device. Background Technology

[0002] In current road infrastructure construction, manholes, as an important component of urban underground pipe networks, are directly related to the safety of public life and property and the efficiency of urban operations due to their safety and maintenance. While anti-fall nets have traditionally been used as an emergency protection measure to address the risk of pedestrians falling or objects falling from manhole covers due to damage or theft, this solution has revealed many limitations in practical application.

[0003] Traditional fall protection nets are often made of materials susceptible to moisture and mold. Prolonged exposure to the dark and damp environment inside wells not only accelerates the aging and degradation of the materials, leading to a significant decrease in the net's tensile strength, but also can cause deformation and unevenness in the mesh due to mold growth, thus weakening its protective effectiveness. Furthermore, the knot design of traditional fall protection nets is often not stable enough, making them prone to shifting under stress, and thus unable to effectively prevent falls under all circumstances.

[0004] More seriously, if heavy or dangerous objects accidentally fall into the well, these hazards are often difficult to detect in time because the safety nets themselves lack real-time monitoring or alarm functions. This increases the difficulty of subsequent cleanup and the possibility of safety accidents. Especially in densely populated or busy areas, the potential threat of such safety hazards cannot be ignored. Therefore, there is an urgent need for a device that can monitor the environment inside the well and promptly detect any fallen objects. Summary of the Invention

[0005] To address the issue of heavy or dangerous objects accidentally falling into road manholes, where the safety nets themselves lack real-time monitoring or alarm functions, these hazards are often difficult to detect in a timely manner, thus increasing the difficulty of subsequent cleanup and the occurrence of safety accidents.

[0006] This invention provides a manhole fall monitoring device, comprising an infrared lens ring and an infrared sensor fixedly installed inside the manhole. The infrared lens ring includes an annular steel strip and multiple infrared cameras evenly distributed on the annular steel strip. The infrared cameras are electrically connected to the infrared sensors, and the infrared sensors are electrically connected to a signal receiving and monitoring device for alerting personnel.

[0007] As a preferred embodiment, the annular steel strip is provided with a retaining ring to connect to the manhole wall, the retaining ring is provided with bolts to fix it to the manhole wall, and the annular steel strip is disposed inside the retaining ring.

[0008] As a preferred embodiment, the infrared cameras are fixedly mounted on the annular steel strip, and there are 3 to 6 infrared cameras.

[0009] As a preferred embodiment, the infrared lens ring is positioned in the upper third of the inspection well area, and the infrared camera's shooting angle is a downward deflection of 30 to 60 degrees from the horizontal.

[0010] As a preferred embodiment, the infrared camera is electrically connected to the infrared sensor via wires, and the wires are fixedly connected at multiple points close to the inspection well wall.

[0011] As a preferred embodiment, the infrared sensor is equipped with a power supply that powers both the infrared sensor and the infrared camera.

[0012] As a preferred embodiment, the signal receiving and monitoring device is equipped with a wire or radio connection to an infrared camera.

[0013] The beneficial effects of this invention are as follows: This invention employs an infrared camera, sensor, and signal receiving monitoring device as a protective measure. The principle is that when a foreign object falls into a manhole or a person falls in, the infrared camera first detects the object, then the circular infrared camera transmits the information to the sensor, which sends a signal. Finally, the signal receiving device receives the signal and issues an alarm. When heavy or dangerous objects accidentally fall into road manholes, this invention can monitor and alarm in real time, enabling staff to promptly detect these hazards and thus solving the problems of difficult subsequent cleanup and frequent safety accidents. Attached Figure Description

[0014] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings, wherein... Figure 1 A schematic diagram of the structure of the present invention.

[0015] The numbers in the attached diagram are: 1. Infrared camera; 2. Infrared sensor; 3. Power supply; 4. Circular steel strip; 5. Signal receiving and monitoring device; 6. Wire. Detailed Implementation

[0016] To illustrate the features of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example: Please see Figure 1This invention provides a manhole fall monitoring device, comprising an infrared lens ring and an infrared sensor 2 fixedly installed inside the manhole. The infrared lens ring includes an annular steel strip 4 and six infrared cameras 1 evenly distributed on the annular steel strip. The shooting angle of the infrared cameras 1 is generally 60 degrees. Evenly distributed three infrared cameras 1 can achieve a shooting coverage rate of over 90% inside the manhole, and evenly distributed six infrared cameras 1 can achieve full coverage. In this embodiment, to ensure monitoring quality, six infrared cameras 1 are selected. The infrared cameras 1 are electrically connected to the infrared sensor 2, and the infrared sensor 2 is electrically connected to a signal receiving and monitoring device 5 for warning personnel. Through the signal chain formed by the infrared cameras 1, infrared sensors 2, and signal receiving and monitoring device 5, timely monitoring of the manhole environment is achieved, and operators are alerted to potential falls to avoid safety accidents.

[0018] In addition, in this embodiment, the annular steel strip 4 is provided with a retaining ring to connect to the inspection well wall. Specifically, the retaining ring is bolted to the inspection well wall. The annular steel strip 4 passes through the retaining ring and is hung on the well wall by the retaining ring. The infrared camera 1 is fixedly installed on the annular steel strip 4. Fixed and evenly distributed installation is the optimal solution to ensure the maximum monitoring angle.

[0019] The infrared lens ring is set in the upper third of the inspection well area, and the shooting angle of the infrared camera 1 is 45 degrees downward from the horizontal angle. This can avoid missed detection and prevent it from being impacted by external forces due to being too close to the manhole cover.

[0020] In this embodiment, the infrared camera 1 is electrically connected to the infrared sensor 2 via a wire 6. The wire 6 is fixedly connected to the inspection well wall at multiple points. Specifically, multiple fixing clips are set to fix the wire 6 in multiple sections at different positions to prevent the wire 6 from being damaged by falling objects.

[0021] The signal receiving and monitoring device 5 is equipped with a radio connection to the infrared camera 1. Because radio power consumption is relatively high, the power supply 3 in the infrared sensor 2, which powers both the infrared sensor and the infrared camera, should use a battery with a larger capacity to avoid frequent battery replacements.
