Description

Technical Field

[0001] This utility model mainly relates to the field of cabinets, specifically to a heat-insulating and insulating liner for a cabinet manhole. Background Technology

[0002] In industries such as shipbuilding, petrochemicals, and energy storage, various containers (such as liquid cargo tanks, fuel oil tanks, ballast water tanks, and chemical storage tanks) are core storage and transportation units. To facilitate internal inspection, maintenance, and cleaning, these man-made containers must be equipped with manholes. As large opening structures on the container walls, the sealing and thermal insulation performance between the manhole cover and the container body (or flange) is crucial.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Traditional gaskets or bushings primarily focus on sealing performance (preventing media leakage), and their thermal insulation performance is usually very limited. Even when using some insulating materials (such as rubber), their thermal conductivity is still much higher than that of professional thermal insulation materials, and they are prone to aging and failure under long-term temperature and pressure cycling, resulting in a simultaneous decline in both thermal insulation and sealing performance.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] This utility model provides a heat-insulating and insulating bushing for a manhole in a cargo compartment, in order to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is: a heat-insulating and insulating bushing for a manhole in a cargo hold, comprising a manhole structure in the cargo hold, wherein a bushing structure is provided inside the manhole structure in the cargo hold;

[0010] A bushing structure includes a bottom bushing, a side bushing on the outer side of the bottom bushing, an inner bushing on the inner side of the bottom bushing, a slot on the inner side of the inner bushing, and a rotating bushing on the inner side of the bottom bushing.

[0011] Furthermore, the manhole structure includes a manhole body, a positioning ring is provided in the middle of the inner wall of the manhole body, a placement groove is provided in the middle of the inner wall of the manhole body, and a support frame is provided at the bottom of the manhole body.

[0012] Furthermore, the top of the support frame is rotatably connected to an electric push rod, and the top of the electric push rod is rotatably connected to a rotating bar, with a positioning hole on one side of the rotating bar.

[0013] Furthermore, the number of rotating bars is set to multiple, and the multiple rotating bars are arranged in a circular array inside the positioning ring.

[0014] Furthermore, the top of the rotating bushing is provided with horizontal and vertical strips, which are perpendicularly intersecting each other.

[0015] Furthermore, a retaining strip is provided at the bottom of the rotating bushing, and the retaining strip engages with the positioning hole.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This invention effectively seals the manhole by using a bottom bushing and a rotating bushing that work together. When sealing the manhole is required, the cover enters the manhole body of the compartment, and then an electric push rod drives the rotating bar to rotate. The rotating bar drives the rotating bushing to rotate 90°, allowing the rotating bushing to effectively seal the inside of the cover. This quickly achieves a seal on the manhole body of the compartment, sealing the cover from three sides and preventing leakage. Attached Figure Description

[0030] See attached document Figure 1-4 A heat-insulating and insulating bushing for a cabinet manhole, comprising a cabinet manhole structure 1, wherein a bushing structure 2 is provided inside the cabinet manhole structure 1;

[0031] The bushing structure 2 includes a bottom bushing 201, a side bushing 202 on the outer side of the bottom bushing 201, an inner bushing 203 on the inner side of the bottom bushing 201, a slot 204 on the inner side of the inner bushing 203, a rotating bushing 205 on the inner side of the bottom bushing 201, a horizontal bar 206 and a vertical bar 207 on the top of the rotating bushing 205, the vertical bar 207 and the horizontal bar 206 intersecting perpendicularly, and a retaining strip 208 at the bottom of the rotating bushing 205. The retaining strip 208 engages with the positioning hole 107. When the cover enters the interior of the manhole body 101 of the cabinet and needs to... When sealing the cap using the bushing structure 2, the bottom and outer sides of the cap are in contact with the top of the bottom bushing 201 and the inner side of the side bushing 202. Then, the electric push rod 105 is activated, which drives the rotating bar 106 to rotate. The rotating bar 106 pushes the positioning hole 107 to rotate, and the positioning hole 107 drives the rotating bushing 205 to rotate. The rotating bushing 205 drives the top horizontal bar 206 and vertical bar 207 to be in contact with the inner side of the cap and to press the cap, so that the inner side of the cap is tightly fitted with the bottom bushing 201, the side bushing 202 and the rotating bushing 205, thereby enabling the cap to be pressed from different directions.

[0032] Furthermore, the manhole structure 1 includes a manhole body 101, a positioning ring 102 disposed in the middle of the inner wall of the manhole body 101, a placement groove 103 formed in the middle of the inner wall of the manhole body 101, a support frame 104 disposed at the bottom of the manhole body 101, an electric push rod 105 rotatably connected to the top of the support frame 104, a rotating bar 106 rotatably connected to the top of the electric push rod 105, and a positioning hole 107 formed on one side of the rotating bar 106. The number of rotating bars 106 is set to multiple, and the multiple rotating bars 106 are arranged in a ring array inside the positioning ring 102. When it is necessary to install the bushing structure 2 inside the manhole structure 1 of the cabinet, the bottom bushing 201 is placed inside the positioning ring 102, and then the side bushing 202 on the outer side of the bottom bushing 201 is attached to the inner wall of the placement groove 103. Then, the retaining strip 208 at the bottom of the rotating bushing 205 on the outer side of the bottom bushing 201 is placed into the positioning hole 107 for engagement, thereby installing the bottom bushing 201.
