Description

Technical Field

[0001] The utility model relates to the technical field of application equipment for external floating roof storage tanks, in particular to a cable storage device for external floating roof storage tanks. Background Art

[0002] At present, large external floating roof tanks are used for crude oil reserves at home and abroad. External floating roof tanks are mainly composed of tank body and floating plate. The tank body and floating plate are connected by a ladder, and personnel can enter the floating plate of the tank through the ladder. The floating plate moves up and down with the change of the tank liquid level. When the tank liquid level rises, the floating plate moves up with the liquid level. When the tank liquid level drops, the floating plate moves down with the liquid level.

[0003] For safety reasons, some electrical instrumentation equipment is installed on the floating plate of the external floating roof tank. The cables of the electrical instrumentation equipment on the floating plate move up and down because the floating plate moves up and down. When the floating plate is at a high position, the cable length required for the electrical instrumentation equipment on the floating plate is shorter. When the floating plate is at a low position, the cable length required for the electrical instrumentation equipment on the plate is longer. According to the domestic storage tank of 100,000 cubic meters, the cable length required for the low and high positions of the floating plate differs by about 20 meters. Therefore, when the storage tank is at a high liquid level, a large number of cables will be piled on the floating plate. Moreover, when the liquid level of the storage tank drops from a high position to a low position, if the cables on the floating plate are not properly arranged, as the floating plate descends, it is very likely that the cables will be torn off, which may damage the cables at the least and may cause safety accidents at the worst.

[0004] In order to prevent a large number of cables from being piled on the floating plate of an external floating roof tank when the liquid level is high, and to prevent the risk of cables being torn off when the tank drops from a high liquid level to a low liquid level, an external floating roof tank cable storage device is added to the original tank ladder, thereby solving the above problems well.

[0031] This configuration of the present embodiment can ensure that the cable storage box 400 can move along with the movement of the ladder 300 without affecting the cable storage box 400 from changing its own shape during the movement, thereby ensuring smooth storage and release of the cables 500 .

[0032] In one embodiment, the cable storage box 400 includes rectangular frames connected in sequence, and the adjacent rectangular frames are hinged. In this embodiment, the tank chain type cable storage box is set up so that the overall shape of the cable storage box 400 can be maintained when the ladder drives the cable storage box 400, so that the cable 500 moves in a fixed direction and line.

[0033] In one embodiment, the movable end of the cable storage box 400 is fixedly connected to the ladder 300 via a support rod 403. This embodiment is configured in this way to improve the stability of the cable storage box 400 and maintain synchronous movement with the ladder 300.

[0034] In one embodiment, a wheel disc 301 is provided at the end of the ladder 300 facing the floating plate 200, and the wheel disc 301 is movably arranged on a ladder guide rail 302, and the ladder guide rail 302 is fixed on the floating plate 200. In this embodiment, the ladder 300 can move smoothly following the movement of the floating plate 200, thereby driving the cable 500 to move synchronously.

[0035] It should also be noted that the end of the ladder 300 away from the floating platform 200 is rotatably connected to the external bracket.
