Description

Technical Field

[0001] The utility model relates to the technical field of valve wells, in particular to a well cover for a gas valve well. Background Art

[0002] With the widespread adoption and expansion of urban gas pipeline systems, the safe operation of gas valve wells, as a crucial component of these systems, is crucial. Gas leaks can lead to serious accidents such as fires and explosions. Therefore, the design of gas valve well covers must ensure safety. Gas valve wells are typically located outdoors and must withstand the elements, including temperature fluctuations, wind and rain, and vehicle traffic. Therefore, the materials and technology used for these covers must offer excellent weather and impact resistance. Regular inspection and maintenance are required to promptly identify and address any issues within the gas pipeline system. Therefore, the covers should be designed to facilitate both routine maintenance and rapid response in emergencies.

[0003] In actual use, due to the loose locking structure, the manhole cover may accidentally open when subjected to slight external force or vibration, increasing the risk of people or equipment falling into the well and reducing safety of use. The easy opening of the manhole cover may cause maintenance personnel to be unable to ensure that the manhole cover is always closed during maintenance, increasing the risk and inconvenience during the maintenance process. In the gas valve well, the accidental opening of the manhole cover may cause gas leakage, increase the risk of fire and explosion, and pose a threat to the environment and personnel safety. Utility Model Content

[0004] The purpose of the utility model is to provide a manhole cover for a gas valve well. The design of the slots and the rotating column allows the manhole cover to rotate around the axis, so that it is convenient to open and close, which is convenient for daily maintenance and rapid response in emergency situations. The design of the rotating block can increase the stability of the manhole cover, prevent accidental opening due to accidental impact or external force, and reduce safety hazards. Since the manhole cover can be easily rotated, maintenance personnel can more easily access the facilities under the manhole cover for inspection and maintenance.

[0005] To achieve the above-mentioned object, a manhole cover for a gas valve well is provided, comprising: a pipeline, wherein the pipeline is fixedly connected to a first fixing block, a top end of the first fixing block is provided with a C-shaped groove, a second fixing column is slidably connected inside the C-shaped groove, a top end of the second fixing column is fixedly connected to the manhole cover, a top end of the manhole cover is provided with a slot, a second fixing block is rotatably connected inside the slot, a bottom end of the second fixing block is fixedly connected to a rotating column, and the rotating column extends to the bottom end of the manhole cover, and a rotating block is fixedly connected to the bottom end of the rotating column;

[0006] The bottom end of the manhole cover is fixedly connected to a second stopper, and the left and right sides of the second stopper are fixedly connected to third stoppers. The interior of the third stopper is slidably connected to a first fixing post. The rear end of the first fixing post is fixedly connected to a fourth stopper, and a spring is sleeved on the outer ring of the first fixing post. One side of the fourth stopper is fixedly connected to a stopper, and the outer ring of the stopper is sleeved with the first stopper. The top of the first stopper is fixedly connected to the manhole cover. This structural design ensures the precise positioning and automatic reset of the manhole cover, improving its efficiency and safety.

[0007] According to the manhole cover for a gas valve well, the outer ring of the first fixing block is provided with four positioning holes. The design of the positioning holes facilitates the installation and fixation of the manhole cover, and improves installation efficiency and accuracy.

[0008] According to the manhole cover for a gas valve well, the bottom end of the pipeline is fixedly connected to a base plate, the outer ring of the pipeline is fixedly connected to a gas protection pipe, and the interior of the gas protection pipe is connected to the interior of the pipeline. This design enhances the protection capability of the pipeline and improves the safety of the gas system.

[0009] According to the gas valve well cover, the second fixing block has a cross-shaped cross section, and its dimensions match the interior of the slot. The cross-shaped cross-section enhances the strength and stability of the fixing column, improving the load-bearing capacity of the well cover.

[0010] According to the manhole cover for a gas valve well, the cross-section of the rotating block is in the shape of a lowercase "B," and the rotating block and the limit post abut against each other. The small "B" cross-section design makes the abutment between the rotating block and the limit post more uniform, thereby improving the opening efficiency and stability of the manhole cover.

[0011] According to the manhole cover for a gas valve well, there are four limit posts, each of which is provided with a second limit block and three first limit blocks. The design of multiple limit blocks enhances the positioning and fixing capabilities of the manhole cover, and improves the stability and safety of the manhole cover.

[0012] According to the manhole cover for a gas valve well, each second limit block is provided with two third fixing blocks, two first fixing columns, two springs, and two fourth fixing blocks. This combined design makes the connections between the various components of the manhole cover more secure, improving the strength and durability of the overall structure.

[0013] According to the manhole cover for a gas valve well, there are two gas protection pipes, each having a D-shaped cross section. The D-shaped cross section enhances the strength and pressure resistance of the gas protection pipe, improving the safety of the gas system.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a slot, a second fixed block, a rotating column and a rotating block. The design of the slot and the rotating column allows the manhole cover to rotate around the axis, so that it is convenient to open and close, which is convenient for daily maintenance and rapid response in emergency situations. The design of the rotating block can increase the stability of the manhole cover, prevent it from being accidentally opened due to accidental impact or external force, and reduce safety hazards. Since the manhole cover can be easily rotated, maintenance personnel can more easily access the facilities under the manhole cover for inspection and maintenance.

[0016] 2. The utility model is provided with a second limit block, a third fixed block, a first fixed column, a fourth fixed column, a spring, a limit column and a first limit block. The manhole cover is stabilized in the horizontal direction by the fixation of the second limit block and the third fixed block to prevent the manhole cover from tilting or moving when subjected to external force. The sleeve design of the spring enables the manhole cover to automatically reset to its initial position after closing without manual adjustment, thereby improving ease of use. The design of the first fixed column and the fourth fixed block evenly distributes the pressure on the manhole cover, reduces stress concentration at a single point, and extends the service life of the manhole cover.
