Description

Technical Field

[0001] This utility model belongs to the field of LNG transportation technology, and in particular relates to a protective device for unloading hoses. Background Technology

[0002] The primary function of the LNG unloading hose is to serve as a transfer channel for LNG from the transport tanker truck to the storage tank at the refueling station. Flange connectors at both ends of the hose ensure a quick and sealed connection with the tanker truck and storage tank. After unloading, the hose must be properly cleaned and stored in a designated location, avoiding unnecessary bending and stretching.

[0003] After the LNG unloading hoses are used, the process is primarily manual, requiring operators to manually install blind flanges and tighten bolts at the hose flange joints. During operation, care should be taken to avoid haphazard placement that could lead to tangling and dragging on the ground, causing wear to the joints. The sealed unloading hoses must be properly placed in designated locations within the unloading area. However, manual operation is inefficient, and the extremely low temperature of LNG poses a risk of cryogenic damage from accidental contact. Furthermore, the on-site discharge of residual LNG could cause environmental harm and operational safety hazards. Utility Model Content

[0037] This utility model embodiment provides a protective device for unloading hoses, such as... Figures 1 to 4 As shown, the protection device mainly includes a base 1, a drive component 4, and a sealing and discharge component 2.

[0038] The base 1 has a support platform 12, which can support the unloading hose 3. The support platform 12 can support either end of the unloading hose 3.

[0039] The sealing and discharge component 2 includes a sealing element 21, which has a frustum portion and a discharge chamber 22 disposed on the frustum portion and communicating with the outside.

[0040] The frustum portion is coaxial with the unloading hose 3. The diameter of the larger outer diameter end of the frustum portion is greater than the diameter of the unloading hose 3, and the outer diameter of the smaller outer diameter end is smaller than the diameter of the unloading hose 3, and it is aligned with the opening of the unloading hose 3. The frustum portion of the sealing member 21 can be inserted into the opening of the unloading hose 3 to directly seal the opening of the unloading hose 3.

[0041] The driving component 4 is connected to the sealing component 21 to drive the sealing component 21 to move along the axial direction of the unloading hose 3 to block or open the opening of the unloading hose 3.

[0042] Simultaneously, during the process of sealing the opening of the unloading hose 3, the sealing component 21 connects the unloading hose 3 and the discharge chamber 22. The liquid remaining in the unloading hose 3 can flow directly into the discharge chamber 22 and then flow to the outside through the discharge chamber 22.

[0043] The protective device of this invention has a support platform on the base 1 that can support the unloading hose 3. The driving component 4 drives the frustum portion of the sealing component 21 to seal or open the opening of the unloading hose 3. When sealing the opening of the unloading hose 3, the unloading hose 3 is connected to the discharge chamber 22, and residual liquid is discharged through the exhaust chamber. This protective device improves the sealing efficiency by driving the sealing component 21 to seal the unloading hose 3, and the discharge of residual liquid through the discharge chamber 22 eliminates the possibility of direct human contact with LNG. The residual liquid is centrally released through the EAG pipeline, solving the risk of freezing and environmental hazards caused by on-site discharge of residual LNG / BOG.

[0044] like Figure 5 and Figure 6 As shown, in some embodiments, the sealing and discharging component 2 further includes a discharging pipe 23, which is connected to the sealing component 21 and communicates with the outside and the discharging chamber 22. Liquid flowing into the discharging chamber 22 can flow to the outside through the discharging pipe 23.

[0045] A check valve can be installed on the discharge pipe 23 to prevent backflow of liquid.

[0046] The sealing component 21 and the discharge pipe 23 in this application embodiment can be connected in various ways. The discharge pipe 23 can be connected to the sealing component 21 via bolts or other detachable methods, thereby achieving rapid assembly. Alternatively, the sealing component 21 and the discharge pipe 23 can be an integral structure, facilitating processing.

[0047] In some embodiments, the discharge pipe 23 may be located on the end face of the end with the larger outer diameter of the two opposite ends of the plug 21, thereby ensuring that the plug 21 does not interfere with the opening of the unloading hose 3 when it is inserted into the unloading hose 3.

[0048] The sealing member 21 has a passage arranged along its axial direction. The passage extends to the end face of the end with the larger diameter of the sealing member 21. The discharge pipe 23 can be connected to the passage to discharge the residual liquid in the discharge chamber 22.

[0049] In some embodiments, the driving member 4 can be a linear driving member, which can be fixed on the base 1. The driving part of the linear driving member is connected to the sealing member 21 and is used to drive the sealing member 21 to block the unloading hose or open the unloading hose.

[0050] For example, such as Figure 1 As shown, the driving component 4 can be a driving cylinder. The driving component 4 is located on the side of the sealing component 21 away from the unloading hose 3. The piston rod of the driving component 4 can be connected to the end of the sealing component 21 with a larger outer diameter through the connector 41. The movement of the sealing component 21 is driven by the extension and retraction of the piston rod.

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the base 1 further includes a box 10 and a drawer cabinet 13 disposed at the bottom of the box 10. The shelf 12 can be disposed inside the box 10, and the drawer cabinet 13 is slidably connected to the box 10. For example, the drawer cabinet 13 can be connected to the box 10 via a slide rail structure.

[0052] The drawer cabinet 13 can hold some tools related to the installation and on-site operation of the unloading hose 3, which makes it convenient for staff to maintain and install the equipment on-site.

[0053] The number of drawer cabinets 13 is not specifically limited and can be one or more. The openings of the drawer cabinets 13 on the box body 10 can be located below the unloading hose 3.

[0054] In some embodiments, the enclosure 10 can be formed by bending and welding 304 stainless steel, and the thickness of the enclosure 10 is 5mm. Anchor bolt holes can be provided at the bottom of the enclosure 10 for connecting anchor bolts. The sidewalls of the enclosure 10 can be a grid structure, wherein the porosity is ≥60%.

[0055] In some embodiments, the housing 10 has a slot 14 on its wall, which extends to the top of the housing wall, and the unloading hose 3 can be inserted into the slot 14 to stabilize the unloading hose 3.

[0056] In some embodiments, the top of the housing 10 is open, and the base 1 also includes a cover 11 rotatably connected to the housing 10. The cover 11 is rotatable relative to the housing 10 to open or close the housing 10, thereby preventing dust, rainwater and foreign objects from entering the housing 10.

[0057] In some embodiments, the discharge chamber 22 on the sealing member 21 extends to the end face of the end with the smaller outer diameter among the two opposite ends of the sealing member 21. When the sealing member 21 blocks the unloading hose 3, the liquid in the unloading hose 3 can flow directly into the discharge chamber 22, thereby achieving rapid discharge of residual liquid.

[0058] In some embodiments, the support platform 12 may have a V-groove with the groove opening facing upwards. Typically, the unloading hose 3 has a flange 31 at its opening, which can be directly inserted into the V-groove to ensure that the opening of the unloading hose 3 is aligned with the smaller diameter end of the sealing member 21. The stability of the unloading hose 3 on the housing 10 can be ensured by the interaction between the V-groove on the support platform 12 and the slot 14 of the housing 10.

[0059] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
