Description

Technical Field

[0001] This utility model relates to the field of pressure vessel protection technology, specifically a pressure vessel anti-collision protection device. Background Technology

[0002] A pressure vessel is a sealed device that holds gas or liquid under pressure. The importance of external protection for pressure vessels is mainly reflected in the following aspects: Ensuring safety: Pressure vessels are commonly used in industrial production to store or transport high-pressure gases, liquids, or chemicals. Inadequate protection can lead to serious consequences. Protective measures can reduce the likelihood of accidents and protect the lives of surrounding personnel. Extending service life: Protective measures can mitigate corrosion, fatigue, and external impacts on the pressure vessel, thereby extending its service life. Ensuring stable operation: Reasonable protective measures can prevent the vessel from being affected by external interference (such as high temperature, low temperature, mechanical impact, etc.), ensuring the stable operation of the production process.

[0003] Currently, the typical solution for external protection of pressure vessels is to weld reinforcing rings, cross supports, or anti-collision beams on the outside. However, welding or bolting prevents the release of thermal expansion and contraction stress, accelerating fatigue cracks in the vessel wall. Moreover, the welded protective device is a monolithic structure, which is inconvenient for later maintenance. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing a pressure vessel anti-collision protection device. It employs a multi-stage energy dissipation method to protect the vessel body and improve the protective effect. Furthermore, the device and the pressure vessel are in contact, avoiding damage to the pressure vessel's sidewalls caused by welding or bolted connections. Moreover, the device adopts a modular splicing structure, which facilitates disassembly and maintenance, reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure vessel anti-collision protection device includes a protective sleeve surrounding the outside of the pressure vessel. The protective sleeve is composed of multiple protective plates spliced ​​together along the circumference. The lower end of the protective plate is provided with a support plate. The rear side of the protective plate is connected to a bracket that can slide up and down. The bracket rests against the inside of the pressure vessel.

[0007] Preferably, the protective plate has an internal cavity containing multiple buffer rods.

[0008] Preferably, the protective plate is provided with a rod and a slot on both sides, and adjacent protective plates are connected by the rod and the slot.

[0009] Preferably, the protective plate has locking bolts for fixing the insert rod on its side wall.

[0010] Preferably, the support plate is provided with fixing holes.

[0011] Preferably, the inner side of the protective plate is connected to a guide rod via an ear plate, the bracket includes a support rod and a top plate, one end of the support rod is connected to a sliding sleeve that cooperates with the guide rod, the sliding sleeve is provided with a positioning bolt, and the other end of the support rod is connected to the top plate.

[0012] Preferably, each of the top plates is connected to two support rods, and the two support rods are connected by a connecting plate.

[0013] Preferably, the end of the support rod is provided with a hanging block, and the side wall of the top plate is provided with a hanging groove that cooperates with the hanging block.

[0014] Preferably, a buffer strip is provided on the side wall of the top plate that contacts the pressure vessel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model adopts a multi-stage energy dissipation method: first-stage buffering: external impact force is dispersed by the rigid shell of the protective plate; second-stage energy absorption: the internal buffer core absorbs impact energy through plastic deformation or compression; third-stage attenuation: the top plate buffer strip reduces the transmission of residual vibration, protects the container body, and improves the protective effect; moreover, the device and the pressure vessel are in contact, avoiding the problem of damage to the side wall of the pressure vessel due to welding or bolt connection; and the device adopts a modular splicing structure, which is convenient for disassembly and maintenance, and reduces costs.

[0017] 2. The height of the bracket of this utility model can be adjusted according to actual use to allow for interface clearance. The top plate can be replaced according to pressure vessels of different diameters, resulting in better adaptability. It also supports the replacement of damaged parts without removing the protective cover. Attached Figure Description

The support 3 is placed against the inner side of the pressure vessel 2 to ensure the stability of the protective sleeve. At the same time, holes can be opened on the protective plate 1 to arrange pipes according to actual needs. The height of the top plate 306 can be made according to usage requirements.

[0027] like Figure 4 As shown, the protective plate 1 has an internal cavity, and multiple buffer rod cores 107 (such as polyurethane foam cores or metal yield-type energy dissipation rods) are installed inside the cavity, which are filled with shear thickening fluid. The buffer rod cores 107 can be arranged in parallel or in a 30° cross mesh pattern to improve multi-directional impact resistance.

[0028] The protective plate 1 has a rod 101 and a slot 102 on both sides, and adjacent protective plates 1 are connected by the rod 101 and the slot 102.

[0034] A buffer strip 308 is provided on the side wall of the top plate 306 that contacts the pressure vessel 2. The buffer strip 308 is a high-damping rubber strip (Shore hardness 60A) that is in flexible contact with the outer wall of the vessel.
