Problems solved by technology
However, the monitoring equipment installed in the valve well needs to solve the problem of data transmission. There are two current solutions. One is to install the monitoring equipment together with the antenna in a safe place on the surface. The disadvantage of this method is that excavation is required. On the pavement, connect the probe of the pipeline with the monitoring equipment through the signal line, and the above-ground and underground projects are relatively large; the second is to install the monitoring equipment together with the antenna in the well. After the manhole cover is put on, no matter where the antenna is placed in the well, the wireless signal is shielded very weakly, and the bit leakage rate is high, so communication cannot be guaranteed

The invention discloses an antenna installation structure of an underground pipeline monitoring device. The structure comprises a pipeline under the pavement and a vertical valve well connecting the pavement with the pipeline, wherein a concrete layer is next to the well wall of the valve well and a self-powered monitoring device is located in the valve well and is coupled with the pipeline. An antenna well internally provided with a wireless antenna is excavated at the uppermost end of the concrete layer. A feed line of the wireless antenna passes through the concrete layer and the well wall of the valve well and is then connected with the monitoring device. The antenna well is divided into two parts, wherein the upper part is big and the lower part is small. The wireless antenna is in the upper part of the antenna well and the lower part of the antenna well is in a cylindrical shape where the feed line passes through. According to the invention, signal shielding condition caused by closing the well cover of the valve well is avoided, and as the monitoring device is in the well, the pavement is not needed to be excavated when the monitoring device is installed. Meanwhile, the communication effect is ensured, and the deficiencies in the prior art are supplemented. The structure provided by the invention can be applied to monitoring projects of underground public pipelines.
Description
technical field [0001] The invention relates to an antenna installation structure in monitoring engineering of underground pipelines. Background technique [0002] There are dense public pipelines buried under the roads and streets of the city. In order to keep abreast of the operation conditions in the pipelines, public companies need to install monitoring devices (such as pressure gauges and flowmeters) on the pipelines and send the monitored information back to the monitoring center. . To install equipment on the pipeline, in order to expose the pipeline, it is necessary to excavate the road surface. In order not to affect the traffic, the engineers hope to install the monitoring equipment in the original valve well of the pipeline. After the monitoring equipment obtains the information of the pipeline, it transmits it to the antenna, and the antenna is responsible for sending the signal to the monitoring center. However, the monitoring equipment installed in the valve...
