Description

Technical Field

[0001] The utility model relates to the technical field of urban gas safety inspection, in particular to an urban gas valve well inspection auxiliary device. Background Art

[0002] Gas valve wells are a crucial component of urban gas pipeline networks, and their safety and stability are directly impacted by the smooth operation of residential life and industrial production. Gas valve wells are equipped with various valves and pipelines that control and regulate the flow of gas. However, due to long-term exposure to complex and changing environments, gas valve wells and their internal facilities are susceptible to corrosion and aging, leading to safety hazards such as gas leaks. Therefore, regular inspections of gas valve wells to promptly identify and address potential safety issues are crucial for ensuring urban gas safety.

[0003] To ensure comprehensiveness and accuracy during gas valve well inspections, safety checks require the use of a variety of specialized instruments, including intelligent gas valve well inspection instruments and combustible gas monitors. These intelligent gas valve well inspection instruments monitor gas leaks in the gas pipeline network in real time, including methane concentration, oxygen content, temperature, and humidity monitoring, providing comprehensive data support for inspectors. Combustible gas monitors are specifically designed to monitor methane and other combustible gas concentrations in gas valve wells and adjacent areas of gas pipelines, triggering an alarm if an anomaly is detected. Together, these instruments form a comprehensive safety assurance system for gas valve well inspections and play an irreplaceable role in ensuring gas valve well safety.

[0004] However, during actual inspections, the carrying and use of these multiple instruments has become a pressing issue. Specifically, existing inspection methods often require inspectors to carry multiple instruments during inspections, which not only increases the burden on inspectors, but also requires that multiple instruments be used sequentially during the inspection process, making them inconvenient to place and manage. Especially in the confined space of gas valve wells, the placement and access of instruments is even more difficult, seriously affecting the efficiency and accuracy of inspections. Even more seriously, the inconvenience of carrying instruments can sometimes even cause inspectors to miss certain important inspection items, posing potential risks to the safe operation of gas valve wells.

[0005] Therefore, to address these shortcomings in existing technologies, a city gas valve well inspection assistance device is urgently needed to address the issues of storing and placing multiple instruments while carrying them. This new inspection assistance device should be able to conveniently carry multiple inspection instruments while providing a reasonable amount of storage space, allowing inspectors to easily access and manage these instruments during inspections. By improving the convenience and efficiency of inspections, the safe operation of city gas valve wells can be further guaranteed. Utility Model Content

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] City gas valve well inspection auxiliary device, including a telescopic bag and two side boxes;

[0009] The two side boxes are symmetrically connected at both sides of the telescopic cloth bag. Guide locking structures are provided on both sides of the telescopic cloth bag. The two movable ends of the guide locking structure are respectively connected to the two side boxes, which are used for guiding the two side boxes to move relative to each other and locking them after movement. A handle is provided on the top of the telescopic cloth bag, and the bottom sides of the handle are respectively connected to the tops of the two guide locking structures.

[0010] Preferably, a side opening is provided on one side of the side box, and the interior of the side box is divided into a plurality of accommodating chambers by a plurality of partitions.

[0011] Preferably, movable wheels are installed on both sides of the bottom of each side box, and the height of the side box is greater than the height of the telescopic cloth bag.

[0012] Preferably, the side opening is arc-shaped, and one side of the side opening is connected to an elastic net.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example 1

[0026] See also Figure 1-5 As shown, the city gas valve well inspection auxiliary device of this embodiment includes a telescopic cloth bag 2 and two side boxes 1;

[0027] Expandable Bag 2: The expandable bag 2 is the main component of the device, designed to temporarily accommodate instruments while they are in use. Its retractable nature allows for flexible adjustment of capacity based on the number and size of instruments, ensuring they are properly stored during transport and use. The material used for the expandable bag 2 is typically wear-resistant and waterproof to withstand the harsh conditions of outdoor inspections.

[0028] Side boxes 1: These are crucial storage components, located symmetrically on either side of the telescopic bag 2. Their primary function is to house multiple inspection instruments, such as intelligent gas valve well inspection instruments and combustible gas monitors. The interior of the side boxes 1 is divided into multiple compartments by partitions 10, allowing for storage of instruments based on type and size, preventing collision and damage.

[0029] The guide-locking mechanism is a key component connecting the telescopic bag 2 and the side box 1. Its two movable ends are connected to the two side boxes 1. This mechanism primarily provides a stable guide for the movement of the side boxes 1, ensuring smooth sliding during deployment and retraction. It also provides a locking function, securely locking the side boxes 1 in place after they are moved to the desired position to prevent accidental sliding during use.

[0030] Handle 3: Located at the top of the telescopic bag 2, handle 3 connects to the tops of two guide locking structures on either side of its bottom. Handle 3 is designed to allow inspectors to easily lift the entire device for movement and portability. It is typically U-shaped to provide greater grip comfort and stability, reducing hand fatigue.

[0031] The two side boxes 1 are symmetrically connected to the two sides of the telescopic cloth bag 2. Guide locking structures are provided on both sides of the telescopic cloth bag 2. The two movable ends of the guide locking structure are respectively connected to the two side boxes 1, which are used for guiding the two side boxes 1 to move relative to each other and locking them after movement. A handle 3 is provided on the top of the telescopic cloth bag 2, and the two sides of the bottom of the handle 3 are respectively connected to the top of the two guide locking structures.

[0032] Example 2

[0033] See also Figure 1-5As shown, in the city gas valve well inspection auxiliary device of this embodiment, a side opening 11 is provided on one side of the side box 1, and the interior of the side box 1 is divided into multiple accommodating chambers by a number of partitions 10. Specifically, by setting the partitions 10 in the side box 1, the side box 1 is divided into multiple accommodating chambers. The inspectors can place different instruments in different accommodating chambers according to the type and size of the instruments. In this way, not only the storage of the instruments is more orderly, avoiding confusion and collisions between instruments, but also it is convenient for the inspectors to quickly find and use specific instruments when needed. The effect of improving the standardization of instrument storage and the convenience of use is achieved.

[0034] The side opening 11 is curved, and one side of the side opening 11 is connected to an elastic net 9. Specifically, the curved side opening 11 and the connection of the elastic net 9 make it easier for inspectors to remove or insert instruments from the side box 1, reducing friction between their hands and the edge of the side box 1. The elastic net 9 provides a certain degree of elastic support when removing or inserting instruments, preventing them from falling or colliding with the interior of the side box 1. This improves the comfort and safety of instrument removal and placement operations.

[0035] Example 3

[0036] See also Figure 1-5 As shown, in the city gas valve well inspection auxiliary device of this embodiment, each side box 1 is equipped with movable wheels 5 on both sides of the bottom. The height of the side box 1 is greater than that of the telescopic bag 2. Specifically, by installing the movable wheels 5 on the bottom of the side box 1, when the side box 1 is deployed from the telescopic bag 2, the movable wheels 5 can easily slide on the ground, further facilitating the inspection personnel to access and place the instrument. At the same time, because the height of the side box 1 is greater than that of the telescopic bag 2, even if the side box 1 is deployed, the telescopic bag 2 will not block the rolling of the movable wheels 5. This achieves the effect of improving the mobility and convenience of the side box.

[0037] The guide locking structure includes a center sleeve 4 and two telescopic rods 8 slidably connected to the ends of the center sleeve 4. The two telescopic rods 8 are respectively connected to adjacent side boxes 1. The telescopic rods 8 and the center sleeve 4 are connected by positioning screws 7. One side of the center sleeve 4 is provided with a plurality of positioning holes 6 that are compatible with the positioning screws 7. Specifically, through the coordination of the center sleeve 4, telescopic rods 8 and positioning screws 7 of the guide locking structure, inspectors can easily adjust the degree of expansion of the side boxes 1 and fix them in the desired position by rotating the positioning screws 7. This design not only provides stable guiding and locking functions, but also allows inspectors to flexibly adjust the position and spacing of the side boxes 1 according to actual needs. This achieves the effect of improving the stability of the side box expansion and the adjustment flexibility.

[0038] The handle 3 is U-shaped, with one end of each of its two vertical sections connected to the side walls of the two central sleeves 4. Specifically, the U-shaped handle 3 and its connection to the side walls of the central sleeve 4 provide inspectors with improved grip comfort and stability when lifting the entire device, reducing hand fatigue. Furthermore, the direct connection between the handle 3 and the central sleeve 4 ensures structural stability, preventing deformation or damage caused by uneven force during carrying. This achieves both enhanced carrying comfort and structural stability.

[0039] This program has the following working process:

[0040] During a city gas valve well inspection, inspectors first prepare using the patented city gas valve well inspection auxiliary device. They organize various specialized instruments, such as intelligent gas valve well inspection instruments and combustible gas monitors, into the side boxes 1 on either side, organized by type and size. The side boxes 1 are divided into multiple compartments by partitions 10, ensuring each instrument has its own storage space, preventing collisions and damage. The inspector then easily lifts the entire device using the U-shaped handle 3 on top of the retractable bag 2 and proceeds to the inspection location.

[0041] After arriving at the gas valve well, the inspectors operate the guide locking structure according to actual needs. The guide locking structure consists of a central sleeve 4, a telescopic rod 8 and a positioning screw 7. The telescopic rod 8 is slidably connected to both ends of the central sleeve 4 and is connected to the adjacent side box 1. The inspectors rotate the positioning screw 7 to position it in the positioning hole 6 on the side wall of the central sleeve 4, thereby adjusting and locking the degree of expansion of the side box 1. As the two side boxes 1 move away from each other, the telescopic cloth bag 2 will also open synchronously, providing the inspectors with a larger operating space. At this time, the inspectors can easily take out the required instruments from the arc-shaped side opening 11 of the side box 1 to conduct a safety inspection of the gas valve well. The arc-shaped design of the side opening 11 and the connected elastic net 9 provide a smooth operating experience and safety in taking and placing instruments.

[0042] During inspections, when instruments need to be replaced or other operations need to be performed, inspectors can easily return them to the side box 1 or temporarily place them in the telescopic bag 2. Wheels 5 mounted on the bottom of the side box 1 allow it to slide easily on the ground, further facilitating access and placement of instruments. Furthermore, because the side box 1 is taller than the telescopic bag 2, the telescopic bag 2 does not obstruct the movement of the wheels 5 even when the side box 1 is unfolded, ensuring ease of use.

[0043] After completing the inspection, the inspector simply pushes the side box 1 back into place and relocks it by rotating the positioning screw 7. This restores the device to its portable state and allows the inspector to continue on to the next inspection location. Throughout the inspection process, inspectors no longer need to frequently search for and organize the instrument, significantly saving time and energy and improving inspection efficiency.

[0044] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
