Description

Technical Field

[0001] The invention relates to a cold storage cargo storage shelf, in particular to a mobile shelf for ships. Background Art

[0002] The shelves for ship cold storage are generally welded from stainless steel pipes. To prevent swaying, the lower end of the shelf is fixed to the ground plate, and the upper end is fixed to the top plate. The existing ship shelves have a simple structure and only support the cargo. The shelves are spaced apart from each other, leaving space for air supply and cargo collection. In addition, the air coolers in ship cold storage are generally cabinet-type or ceiling-type, which need to occupy a part of the cold storage space. Therefore, the storage capacity rate of ship cold storage is not high, and can currently reach up to 30%.

[0003] At present, mobile shelves are widely used in warehouses, archives, libraries and other places. These mobile shelves are equipped with rails on the ground for the shelves to move. The swing characteristics of ships are not taken into consideration and they cannot be directly applied to the ship field.

[0004] For example, a mobile shelf (patent publication number: CN 210471530 U) does not have anti-swaying characteristics. The preservation of ship cold storage is a strong guarantee for ocean-going missions, but the ship space is limited, and the cold storage capacity rate needs to be increased as much as possible to ensure sufficient supply of food at sea. Therefore, a mobile shelf for ships is needed. Summary of the invention

[0005] The present invention aims to solve the problem of low storage capacity in the current ship cold storage, and to increase the storage capacity of the cold storage from the original maximum of 30% to 50% while ensuring the fresh-keeping storage effect of the cold storage, and to propose a ship-based mobile shelf.

[0006] The technical solution of the present invention is: a marine mobile shelf, comprising a mobile shelf, an upper roller, an upper guide rail, an upper limit device, a manual rocker, a lower roller, a lower guide rail, and a lower limit device. The upper and lower parts of the mobile shelf body are respectively installed with upper and lower rollers and upper and lower limit devices, and the upper guide rail and the lower guide rail are respectively fixed in the upper and lower panels of the cold storage; the upper and lower rollers are connected by a transmission mechanism and can be controlled by a manual rocker or an electric control panel installed on one side of the mobile shelf body; long core blocks are welded in the middle of the upper and lower guide rails, which cooperate with the limit devices installed on the upper and lower parts of the shelf to limit the rollers and prevent the rollers from slipping off the guide rails; the upper and lower guide rails are both provided with locking and positioning devices for fixing the shelf.

[0007] Furthermore, a drainage hole is provided at the bottom of the lower guide rail for draining condensed water inside the cold storage.

[0008] Furthermore, the transmission mechanism is a chain transmission mechanism, a belt transmission mechanism or a gear transmission mechanism.

[0009] Furthermore, the mobile shelf is welded from stainless steel pipe fittings.

[0010] Furthermore, a plurality of ship-mounted mobile shelves are arranged in the cold storage, wherein at least one row of shelves on the wall side is a fixed shelf, and air coolers are arranged on the lower layers of the shelves. The number of air coolers, i.e. the number of fixed shelves, is determined by the required cooling capacity of the cold storage.

[0011] Furthermore, a cold air fan is arranged on the lower layer of the fixed shelf, and the air supply outlet of the cold air fan is connected to the air supply hole plate on the top of the cold storage through the air supply interlayer on the wall of the cold storage, and the cold air is evenly delivered to the cold storage by the cold air fan through the air supply interlayer and the top air supply hole plate.

[0012] The beneficial effects of the present invention are:

[0013] The upper and lower parts of the mobile shelf for ship of the present invention are equipped with rollers, limit devices and tracks, and the shelf can be moved by manual or electric control. No space for picking up goods is required between the shelves. The air cooler is installed at the bottom of the shelf, which greatly improves the storage capacity of the ship cold storage. In addition, the air cooler is sent to the top of the cold storage through the wall air supply interlayer, and the air is supplied to the cold storage through the top orifice plate. The wall air supply interlayer can form a low-temperature interlayer on the inner wall of the cold storage to reduce heat leakage of the cold storage; the top orifice plate air supply can realize uniform air supply in the cold storage, and this air supply method is more conducive to the preservation effect inside the cold storage.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown, a marine mobile shelf is composed of a mobile shelf 1, an upper limit device 2, a manual rocker 3, a lower limit device 4, a guide rail 5, a guide rail strip core block 6, a roller 7, a transmission mechanism 8, etc. The upper part of the mobile shelf 1 body is installed with a roller 7 and an upper limit device 2, and the lower part is installed with a roller 7 and a lower limit device 4. The upper limit device 2 and the lower limit device 4 are respectively fixed in the upper and lower panels of the cold storage. The roller 7 is connected through a transmission mechanism 8 and can be controlled by a manual rocker 3 or an electric control panel installed on one side of the mobile shelf 1 body. The guide rail strip core block 6 is welded in the middle of the upper and lower guide rails 5 for roller limiting; and the upper and lower guide rails 5 are both equipped with locking and positioning devices, and the locking device can adopt a latch structure to fix the mobile shelf 1. When the shelf moves, the upper and lower guide rails 5 are unlocked at the same time, and when not in use, the upper and lower guide rails 5 can be locked synchronously. The transmission mechanism is a chain transmission mechanism, a belt transmission mechanism, or a gear transmission mechanism.

[0020] The mobile shelf 1 is a mobile shelf body, which can be moved in the upper and lower guide rails 5 by manual rocker 3 or electric control. When moving, the locking devices of the upper and lower guide rails 5 are released, and when not moving, the locking devices of the upper and lower guide rails 5 are locked. A drainage hole is opened at the bottom of the lower guide rail 5 to drain condensed water inside the cold storage.

[0021] The layout of the mobile shelves in the warehouse is as follows: Figure 4 As shown, it includes a mobile shelf 1, a fixed shelf 9, an air cooler 10, a wall air supply interlayer 11, and a top air supply hole plate 12.

[0022] In each row of mobile shelves 1 on the wall side of the warehouse, one or several rows of shelves are fixed shelves 9, which cannot be moved. An internal cooling fan 10 is installed at the bottom of the fixed shelf 9. The internal cooling fan 10 sends cold air to the top air supply hole plate 12 through the wall air supply interlayer 11, and evenly sends the cold air to the cold storage.

[0023] The main body of the new type of mobile shelf for ships is welded from stainless steel pipes. Rollers and rails are installed on the upper and lower parts of the shelf, and both the upper and lower rails are equipped with locking and positioning devices. The mobile shelf can be moved manually or electrically. A cold air blower is installed at the bottom of the shelf, which is sent to the top air supply plate through the wall air supply interlayer, and then the air supply in the warehouse is completed through the top air supply plate. Therefore, the new type of mobile shelf for ships has the following advantages compared with the existing shelves:

[0024] 1) Rollers and limit devices are installed on the upper and lower parts of the shelf to prevent the shelf from swaying on the ship;

[0025] 2) There is a drainage hole at the bottom of the lower rail to drain condensed water inside the cold storage;

[0026] 3) There is no need to leave space for picking up goods between each row of mobile shelves. The goods can be picked up by manually or electrically controlling the mobile shelves, thereby increasing the storage capacity;

[0027] 4) The air cooler is installed at the bottom of the fixed shelf, which does not occupy the internal space of the cold storage and improves the storage capacity;

[0028] 5) The wall has an air supply interlayer to reduce heat leakage in the cold storage and improve the preservation effect;

[0029] 6) The air supply interlayer on the top of the warehouse can make the air supply in the warehouse uniform and improve the preservation effect.
