At present, for the gas pipeline which needs to be laid along the bridge or the building, because the building exists inherently, the construction of the gas pipeline can only be carried out by adopting an external laying mode, but the gas pipeline is difficult to be protected, and when accidents such as earthquake, falling rocks and the like are encountered, the damage of the gas pipeline is easy to be caused, so that the gas leakage is caused to generate safety disasters. And the gas pipeline is exposed to the outside for a long time, and the aging of the gas pipeline can be accelerated under the sun and rain, so that the service life of the gas pipeline is shortened.
For the working state of the gas pipeline, a plurality of gas sensors are also arranged along the gas pipeline to monitor. When gas leaks, the gas sensor can detect the rising of gas concentration, so that abnormal conditions are fed back to the control center through wires or cables, and maintenance personnel are reminded to maintain as soon as possible. However, since the gas pipeline is exposed to the outside, the gas can be quickly released to the air when the gas leaks, so that the gas sensor cannot timely detect the gas leakage condition, and the reporting of the leakage risk is delayed.
Therefore, the utility model provides a gas pipeline protection device laid along with a bridge, which can protect a gas pipeline 400 laid along with the bridge. Specifically, the gas pipeline protection device laid along with the bridge is provided with a support frame 100 for supporting the gas pipeline 400 and a protective shell 200 for coating the gas pipeline 400. When a falling stone accident occurs, the protective case 200 contacts with foreign objects to receive impact, so that the gas pipe 400 is protected from the impact. Moreover, during daily use, protective housing 200 also can shield gas conduit 400 from the wind and rain, reducing the life reduction caused by rain erosion. Further, the present bridge mounted gas pipeline protection device is further provided with a sensor assembly 300 installed inside the protection case 200 for monitoring the operation condition of the gas pipeline 400. The sensor assembly 300 includes a gas probe for detecting a concentration of gas in air, a vibration sensor for detecting whether the protective case 200 or the supporting frame 100 is impacted, and a transmitter for transmitting the detection result to the outside. The protection space 230 constructed by the protection shell 200 slows down the rate of gas emission in the atmosphere, so that the detection of the gas probe is more accurate, and maintenance personnel can be informed of maintenance in time. When the vibration sensor detects external impact, the vibration sensor can also inform maintenance personnel, so that the maintenance personnel can timely perform structural inspection of the gas pipeline 400, and hidden danger of leakage is eliminated before leakage.
Referring to fig. 1, the bridge-mounted gas pipeline protection device in the embodiment of the present utility model includes a support frame 100, a protective shell 200, and a sensor assembly 300. Wherein support frame 100 and protective housing 200 are this gas pipeline protection device's that lays along with bridge body structure, and support frame 100 is used for bearing gas pipeline 400, and protective housing 200 is used for protecting gas pipeline 400.
The number of the support frames 100 is at least two, so that stable support can be provided to the gas duct 400. It should be noted that, referring to fig. 2, a gap is left between two adjacent support frames 100, and a gas pipeline 400 located at the gap is in a suspended state, so that the gas pipeline 400 can contact with the external atmosphere, and high-concentration gas flash explosion caused by filling gas in a closed space when gas leaks is prevented. The top of the supporting frame 100 is used for supporting the gas pipeline 400, and the side is used for being connected with the bridge 500. Specifically, the support frame 100 includes the cross members 110, the vertical beams 120 and the diagonal beams 130 connected to each other, which together form a triangle structure, thereby reducing the self weight of the support frame 100 while improving the structural strength thereof. The transverse beam 110 is used for supporting the protective shell 200 and the gas pipeline 400, the vertical beam 120 is used for being connected with the bridge 500, and the vertical beam 120 is fixedly connected with the bridge 500 specifically through expansion screws.
Further, the support 100 further includes a fixing pipe clamp 140, which is in a "U" shape and is sleeved on the outer wall of the gas pipe 400, and two ends of the fixing pipe clamp 140 are connected with the cross beam 110, so that the gas pipe 400 and the support 100 are tightly combined together through the fixing pipe clamp 140, and the radial displacement of the gas pipe 400 is limited.
The protective case 200 includes a first protective plate 210 and a second protective plate 220 connected to each other, the first protective plate 210 and the second protective plate 220 are bent each other at the connection of the two, and the first protective plate 210 and the second protective plate 220 are connected to the top of the support frame 100. The first protection plate 210, the second protection plate 220 and the support frame 100 together define a protection space 230, and the gas pipe 400 is accommodated in the protection space 230 to be protected. The first protection plate 210 and the second protection plate 220 can protect the top and side surfaces of the gas pipe 400 when a falling stone or other external force intrusion occurs.
Further, the first protection plate 210 is attached to the bridge 500, thereby reducing the gap between the first protection plate 210 and the bridge 500, and reducing the probability that foreign objects fall down and accumulate in the gap. The second protection plate 220 plays a main protection role for the gas pipe 400 and can guide it to roll off from one side of the gas pipe 400 when contacting with foreign objects.
Specifically, in some embodiments, the second protection plate 220 is a planar plate, so as to increase the speed of the foreign object roller. In other embodiments, the second protection plate 220 is a cambered plate, and it is outwardly protruded, so as to be less prone to collapse and deformation when receiving an impact, and has a higher structural strength.
The sensor assembly 300 includes a gas probe, a vibration sensor, and a transmitter, which are connected with the protective case 200 and disposed in the protective space 230. The gas probe is used for detecting the concentration of gas in the air, so as to check whether the gas pipeline 400 has gas leakage; the vibration sensor is used to detect the vibration of the protective case 200 or the supporting frame 100, thereby checking whether an external force impact is applied; the gas probe and the vibration sensor are electrically connected to the transmitter, and the transmitter transmits the detection result to the control center in a wired or wireless mode.
Further, the supporting frame 100 and the protecting shell 200 are stainless steel pieces, so that corrosion of the external environment can be resisted, and the service life of the gas pipeline protecting device laid along with the bridge is prolonged. The supporting frame 100 and the protective case 200 are integrally connected by welding, thereby improving the connection strength.
While the preferred embodiments of the present utility model have been illustrated and described, the present utility model is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present utility model, and these equivalent modifications and substitutions are intended to be included in the scope of the present utility model as defined in the appended claims.
