Description

Technical Field

[0001] The utility model belongs to the technical field of gas pipe network protection, and in particular relates to a municipal gas pipe network safety protection device. Background Art

[0002] Safety protection devices are a combination of equipment and facilities designed to safeguard the safe operation of gas pipeline networks. Gas pipelines are typically installed underground. Urban underground spaces can accommodate a variety of municipal pipelines, including gas pipelines. This prevents clutter in the aboveground space and impacts the urban landscape. Burying the pipeline beneath the road surface reduces the impact of vandalism and environmental factors on the pipeline, making it relatively safer. Some sections of gas pipeline networks require subsurface installation. Therefore, subsurface gas pipeline construction must consider the road's structure and load-bearing capacity to avoid damage to the road and pipeline. However, some roads are subject to heavy vehicles, posing a significant safety hazard to the gas pipelines beneath the road. While initial design features incorporate pressure-resistant structures, over time, the aging of these structures can cause the weight of vehicles to directly impact the pipelines, potentially damaging them. Furthermore, pipeline damage is often not discovered until after workers have learned of it, making it difficult to effectively repair the road and pressure-resistant structures before damage occurs.

[0017] See also Figures 1-4 The utility model provides the following technical solutions: it includes a gas pipeline 1 and a protective assembly 2, the protective assembly 2 includes a lower support shell 21 and an upper support shell 22, the upper support shell 22 is installed on the top of the lower support shell 21, and a slot 23 is provided at the opposite end of the lower support shell 21 and the upper support shell 22, the gas pipeline 1 is installed between the two slots 23, the inner wall of the upper support shell 22 is slidably connected with a lifting top plate 3, and a triangular decompression area 31 is provided at the top of the lifting top plate 3, and a plurality of limiting rings 24 and a plurality of pressure springs 25 are installed on the top of the upper support shell 22, the limiting ring 24 is slidably connected to the inner wall of the upper support shell 22, and the pressure spring 25 is located inside the corresponding limiting ring 24, and a pressure sensor 26 is installed on the top of the limiting ring 24, and the pressure sensor 26 contacts the bottom end of the lifting top plate 3.

[0018] In this embodiment: the protection component 2 protects the gas pipeline 1, and the protection component 2 clamps the gas pipeline 1 through the lower support shell 21 and the upper support shell 22, and makes way for the gas pipeline 1 through two slots 23, so that the protection component 2 can slide up and down on the side of the gas pipeline 1, and the lifting top plate 3 telescopically slides in the upper support shell 22, and the upper support shell 22 supports the lifting top plate 3 through a number of compression springs 25, so that the lifting top plate 3 can provide compression support for the upper soil layer. When the vehicle presses down on the road surface, the pressure is transmitted to the lifting top plate 3 and the triangular pressure relief area 31. The triangular pressure relief area 31 on the top of the lifting top plate 3 can disperse the pressure to both sides, reduce the pressure perpendicular to the gas pipeline 1, and thereby improve the pressure protection effect. When the lifting top plate 3 is under greater pressure, it supports the shell 2 downward. 1 direction, the limit ring 24 limits the lifting top plate 3 to prevent the lifting top plate 3 from descending too much and contacting the gas pipeline 1, causing damage to the gas pipeline 1. The limit ring 24 supports the touch pressure sensor 26, and the touch pressure sensor 26 will not contact the lifting top plate 3 during normal use. When the anti-pressure mechanism under the road surface is aged or damaged, the pressure on the lifting top plate 3 increases. When the lifting top plate 3 descends and contacts and squeezes the touch pressure sensor 26, the touch pressure sensor 26 is triggered. The touch pressure sensor 26 transmits the information about the pressure status of the road surface and the device to the control center through the signal transmission element, so that the staff can be informed of the situation in time and start the inspection or replacement of the anti-pressure mechanism, so as to avoid damage and leakage of the gas pipeline 1 due to the lack of pressure resistance in the future, ensure the safe transportation of gas, and reduce safety hazards.

[0019] Several guide vertical rods 4 are installed at the top of the lower supporting shell 21, and the anti-compression springs 25 are sleeved on the side walls of the corresponding guide vertical rods 4. The top of the guide vertical rods 4 is fixedly connected to the piston plate 41, and several air pressure grooves 32 are opened in the lifting top plate 3. The piston plate 41 is slidably connected to the inner wall of the corresponding air pressure groove 32; the lower supporting shell 21 supports the guide vertical rods 4, and the guide vertical rods 4 limit the anti-compression springs 25 internally, so that the anti-compression springs 25 can always maintain a vertical state to ensure its elastic stability. The piston plate 41 is limited inside the air pressure groove 32 to avoid the lifting top plate 3 from being separated from the lower supporting shell 21 when the anti-compression spring 25 pushes the lifting top plate 3.

[0020] A give way groove 411 is provided at the top of the piston plate 41, and an air pressure sensor 42 is installed in the give way groove 411; the give way groove 411 is consistent with the inner diameter of the air pressure groove 32. When the lifting top plate 3 descends, the piston plate 41 is in a relatively rising state inside the air pressure groove 32, and the give way groove 411 gives way to the air pressure sensor 42 to prevent the air pressure sensor 42 from contacting and being damaged by the lifting top plate 3. The air pressure sensor 42 senses the pressure of the compressed space between the piston plate 41 and the air pressure groove 32. When the detected pressure reaches the set value, the air pressure sensor 42 transmits the data to the command and control center. The air pressure sensor 42 is used in conjunction with the touch pressure sensor 26 to improve the sensitivity during detection. When the air pressure sensor 42 monitors the internal pressure of the air pressure groove 32, the staff can understand and judge the usage status of the anti-pressure mechanism under the road surface according to the change in pressure, which facilitates timely maintenance and ensures its performance and reliability during use.

[0021] A second cavity 33 is provided in the lifting top plate 3, and a plurality of first cavities 27 are provided in the lower supporting shell 21; the second cavity 33 reduces the weight of the lifting top plate 3, and the first cavity 27 reduces the weight of the lower supporting shell 21, making the device lightweight and easy to transfer.

[0022] A plurality of lower grooves 28 are provided at the bottom end of the lower support shell 21, and the positions of the plurality of lower grooves 28 are evenly arranged; the plurality of lower grooves 28 are combined into a wave shape, so that the protective component 2 has a higher grip and friction underground, thereby improving the stability of the device during use, reducing the occurrence of lateral movement of the device, and increasing the contact area of ​​the lower support shell 21 with the soil layer, thereby increasing the support stability of the soil layer.

[0023] When the upper and lower ends of the gas pipe 1 are closed, the upper and lower ends of the gas pipe 1 are closed, and the upper and lower ends of the gas pipe 1 are in a closed state.

[0024] When the lifting plate 3 is under great pressure, it will descend in the direction of the downward supporting shell 21. When the lifting plate 3 descends and contacts the touch pressure sensor 26 and is squeezed, the touch pressure sensor 26 is triggered. At the same time, the air pressure sensor 42 senses the pressure of the compressed space between the piston plate 41 and the air pressure groove 32. When the detected pressure reaches the set value, the air pressure sensor 42 transmits the data to the command and control center. The touch pressure sensor 26 and the air pressure sensor 42 transmit the information of the pressure status of the road surface and the device at this time to the control center through the signal transmission element, so that the staff can know the situation in time and start the inspection or replacement of the anti-pressure mechanism to avoid damage and leakage of the gas pipeline 1 due to the lack of pressure resistance in the future, thereby ensuring the safe transportation of gas and reducing safety hazards.
