Description

Technical Field

[0001] The utility model relates to the municipal field, in particular to a municipal road manhole cover deviation early warning device. Background Art

[0002] At present, municipal road manhole covers do not have the function of deviation warning. According to retrieval and analysis, we found that the current warning design of manhole cover deviation or loss is too complicated. For example, CN103473866A, CN203232544U, and CN 202347538U all introduced wireless transmission modules; CN207092148U, CN203232544U, etc. are equipped with complex mechanical structures; the above designs are costly and have low practical application possibilities. At present, there is a patent that uses an infrared sensor to sense the position of the manhole cover in real time. When the manhole cover is deviated and the infrared light is not blocked, an audible and visual alarm is generated. The design structure is simple and practical, but it is not suitable for situations where the manhole cover is washed away due to floods. Specifically, when floods occur, there is flood between the manhole cover and the infrared sensor, and the flood has poor light-gaining performance, resulting in the manhole cover being washed away. The sound and light alarm still cannot be triggered, which will cause people to fall off the manhole cover. Summary of the invention

[0003] The utility model aims to provide a municipal road manhole cover deviation warning device, which has the characteristics of low cost, sensitive response and low transformation cost.

[0004] The utility model is realized through the following technical scheme: a municipal road manhole cover deviation early warning device comprises an organic glass box, an audible and visual alarm, a power supply, a wire, an alarm connector, a manhole cover connector and a connecting rope; the organic glass box is installed on the manhole wall, the audible and visual alarm and the power supply are installed in the organic glass box, the wire is connected to the audible and visual alarm and extends out of the organic glass box; the end of the wire is connected with the alarm connector, and the manhole cover connector is connected to the manhole cover through the connecting rope; the audible and visual alarm is configured not to alarm when the manhole cover connector and the alarm connector are connected, and not to alarm when the manhole cover connector and the alarm connector are separated.

[0005] Compared with the previous technology, the beneficial effects of the utility model are:

[0006] 1. The equipment and transformation costs are low. The costs mainly lie in the sound and light alarm and power supply in the organic glass box. In actual use, the organic glass box can be replaced and maintained as a whole, and the transformation, maintenance and equipment costs are low.

[0007] 2. The triggering mode is stable. The connection between the alarm connector and the manhole cover connector will not trigger the alarm, otherwise it will trigger an alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Explanation of numbers: 1 plexiglass box, 2 sound and light alarm, 3 wire, 4 alarm connector, 5 manhole cover connector, 6 connecting rope, 61 pig nose buckle, 7 maintenance connector, 8 battery, 9 manhole cover, 91 anti-fall net. DETAILED DESCRIPTION

[0011] The utility model is described in detail below with reference to the accompanying drawings:

[0012] like Figure 1-2 As shown: a municipal road manhole cover deviation warning device includes a plexiglass box 1, an audible and visual alarm 2, a power supply, a wire 3, an alarm connector 4, a manhole cover connector 5 and a connecting rope 6; the plexiglass box 1 is installed on the manhole wall, the audible and visual alarm 2 and the power supply are installed in the plexiglass box 1, the wire 3 is connected to the audible and visual alarm 2 and extends out of the plexiglass box 1; the end of the wire 3 is connected to the alarm connector 4, and the manhole cover connector 5 is connected to the manhole cover through the connecting rope 6; the audible and visual alarm 2 is configured not to alarm when the manhole cover connector 5 and the alarm connector 4 are connected, and not to alarm when the manhole cover connector 5 and the alarm connector 4 are separated.

[0013] The above structure is designed based on the alarm of the co-pilot's seat belt not being buckled. When the manhole cover is displaced, the alarm connector 4 and the manhole cover connector 5 are separated from each other, and the sound and light alarm starts to alarm. It should be noted that in order to ensure that the sound and light alarm and power supply are not easily damaged and prevented from being washed out by floods, the sound and light alarm and power supply are placed in a plexiglass box.

[0014] It should be noted that the sound and light alarm 2 and the power supply are installed in the organic glass box 1, which is to protect the sound and light alarm 2 and the power supply on the one hand, and to facilitate the replacement and maintenance of the product on the other hand. In other words, when the sound and light alarm 2 fails or the power supply is out of power, the sound and light alarm 2 and the power supply can be replaced as a whole by removing the organic glass box 1 and replacing it with a new organic glass box 1. There is no need to troubleshoot and repair on site.

[0015] The sound and light alarm 2 is configured to not alarm when the manhole cover joint 5 and the alarm joint 4 are connected, and not alarm when the manhole cover joint 5 and the alarm joint 4 are separated. It is a conventional circuit connection, so the utility model will not be described in detail.

[0016] The connecting rope 6 is provided with a pig nose buckle 61, so that the length of the connecting rope 6 can be adjusted. When the manhole cover is offset to a certain extent, the alarm connector 4 and the manhole cover connector 5 will be separated, and the sound and light alarm starts to alarm.

[0017] It also includes a maintenance joint 7, which is the same as the alarm joint 4, so that when the maintenance joint 7 is connected to the alarm joint 4, no alarm will be sounded, and when the maintenance joint 7 is separated from the alarm joint 4, no alarm will be sounded. This structure is mainly used for maintenance. When the alarm joint 4 is separated from the manhole cover joint 5, an alarm will be sounded. Therefore, during maintenance, the manhole cover needs to be fully opened. Since the sound and light alarm 2 is placed in the organic glass box 1 and its switch cannot be controlled, the alarm joint 4 is directly replaced with the maintenance joint. After the alarm joint 4 is removed with the manhole cover, the maintenance joint 7 is inserted into the manhole cover joint 5, and the sound and light alarm 2 can be stopped from sounding.

[0018] The power source is a battery 8 or a municipal power source.

[0019] It should be noted that, if necessary, an anti-falling net 91 can be added in the well.

[0020] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
