Description

Technical Field

[0001] This utility model relates to the field of tank switch cover technology, and more specifically, to a vehicle-mounted steel tank switch cover. Background Technology

[0002] In the logistics and chemical storage sectors, vehicle-mounted steel tanks serve as crucial transport containers, and their safety and durability are paramount. Traditional vehicle-mounted steel tank cover designs often prioritize basic sealing and ease of opening. However, when faced with complex and changing transportation environments, especially bumpy roads or impacts from sudden accidents, the structural strength of traditional covers is often insufficient to withstand strong longitudinal pressure, easily leading to deformation or even breakage. This can result in leakage risks, impacting transportation efficiency and potentially posing serious threats to the environment and personnel safety.

[0003] Furthermore, the conduit portion of the vehicle-mounted steel tank's switch cover is susceptible to oxidation and corrosion when exposed to outdoor environments for extended periods. This not only affects the sealing performance of the conduit but may also cause the switch cover to malfunction due to corrosion, shortening the equipment's lifespan and increasing maintenance costs. Although some anti-oxidation measures exist in the existing technology, such as applying anti-corrosion coatings, these methods can only delay the oxidation process to a certain extent and are complex to operate and inconvenient to maintain. Therefore, in response to the above technical problems, a vehicle-mounted steel tank switch cover is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle-mounted steel tank switch cover. By designing a reinforcing rod structure, it effectively resists the large impacts on the vehicle-mounted steel tank, improving the overall structural strength of the switch cover. At the same time, the use of the arc-shaped cylinder and the arc-shaped insert rod further enhances the compressive strength between the reinforcing rods, ensuring that the switch cover remains stable and reliable in harsh environments. In addition, the design of an automatic sealing mechanism protects the conduit area, which is convenient for operation and effectively prevents oxidation, extending the service life.

[0018] The technical solution of this utility model has at least the following beneficial effects:

[0019] 1. When this vehicle-mounted steel tank switch cover is used on a vehicle-mounted steel tank, if the steel tank or the switch cover is subjected to a large impact, the reinforcing rod between the first and second connecting rings will resist the longitudinal pressure, thus protecting the main body of the switch cover. Furthermore, the arc-shaped cylinder and arc-shaped insert between the two sets of reinforcing rods can strengthen and connect the pressure resistance between the reinforcing rods, greatly improving the overall structural strength of the switch cover.

By pulling the fixed block at the end of the connecting rope, the sealing plate can be pulled out under the limit of the slider and the slide groove. At the same time, the tension spring is stretched, which opens the area above the conduit, making it easy to use. When the use of the conduit is over, the drive motor can be reversed to release the wound connecting rope, and the sealing plate can be resealed under the tension of the tension spring, thus protecting the conduit from oxidation. It is quite convenient. Attached Figure Description

A fixing block 18 is fixedly connected to the bottom of the outer side of the fixing cylinder 12, and a tensioning mechanism is installed on the upper side of the switch cover body 1.

[0031] The centers of the first connecting ring 6 and the second connecting ring 7 are coaxial with the main body 1 of the switch cover, and the inner diameter of the second connecting ring 7 is much larger than the inner diameter of the first connecting ring 6, which facilitates the expansion of the protection area.

[0032] The reinforcement mechanism includes an arc-shaped cylinder 9, an arc-shaped insert rod 10, and a fixing bolt 11. The arc-shaped cylinder 9 is fixedly connected to one side of the reinforcing rod 8, and the arc-shaped insert rod 10 is fixedly connected to the other side of the reinforcing rod 8. The end of the arc-shaped insert rod 10 is located inside the arc-shaped cylinder 9. The fixing bolt 11 is threadedly connected to both the arc-shaped cylinder 9 and the arc-shaped insert rod 10.

[0033] The conduit 4 and the cap 5 are located inside the fixing cylinder 12, and the conduit 4 can be placed inside the fixing cylinder 12 for sealing and protection.

[0034] A sealing plate 13 is provided on the inner side of the fixed cylinder 12, and the slot 14 matches the sealing plate 13. The sealing of the fixed cylinder 12 can be guaranteed by the fit between the slot 14 and the end of the sealing plate 13.

[0035] The reset mechanism includes a slide groove 15, a slider 16, and a tension spring 17. The slide groove 15 is located inside the fixed cylinder 12, and there are two sets of slide grooves 15 arranged symmetrically. The slider 16 is fixedly connected to both sides of the sealing plate 13 and is slidably connected to the inside of the slide groove 15. The tension spring 17 is fixedly connected to the inside of the slide groove 15, and the end of the tension spring 17 is fixedly connected to the outside of the slider 16.

In addition, the arc-shaped cylinder 9 and the arc-shaped insert rod 10 between the two sets of reinforcing rods 8 can also strengthen and connect the compressive strength between the reinforcing rods 8, greatly improving the overall structural strength of this switch cover, making it suitable for environments with large impacts without damage, and effectively extending its service life.

[0039] When this switch cover is in use, the outer surface area of ​​the conduit 4 and the cover 5 can be sealed by the fixing cylinder 12 and the sealing plate 13 to prevent oxidation and malfunction. When it is necessary to open the conduit 4 to output internal liquid or to introduce liquid into the vehicle-mounted steel tank, the drive motor 20 can be turned to make the rotating rod 21 drive the connecting rope 22 to wind. By pulling the fixing block 18 at the end of the connecting rope 22, the sealing plate 13 can be pulled out under the limiting sliding of the slider 16 and the slide groove 15. At the same time, the tension spring 17 is stretched to open the upper area of ​​the conduit 4, thus facilitating the use of the conduit 4. When the use of the conduit 4 is finished, the drive motor 20 can be reversed to release the winding connecting rope 22 by the rotating rod 21. The sealing plate 13 will then re-close the upper area of ​​the conduit 4 under the tension of the tension spring 17, thus protecting the conduit 4 from oxidation. This is quite convenient.
