Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a ship. Background Art

[0002] Ships have different ventilation requirements under different working conditions. For example, ships need different ventilation volumes when loading and sailing. Currently, ships on the market usually use two-speed fans to meet ventilation requirements. Two-speed fans usually include high-speed gear and low-speed gear. Operators switch between different gears to meet different ventilation requirements. However, the control cabinet of the two-speed fan is large in size, and it takes up a lot of space on the ship. The control system is complex, and the design and construction require more manpower. In addition, the two-speed fan uses more cables, which increases the procurement cost. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a ship in order to overcome the defects in the prior art that the ship adopts a two-speed fan, which causes inconvenience in construction, requires more manpower in design and construction, and is costly.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a ship, the ship comprising a ventilation system, a cargo hold, a first switch and a second switch, the ventilation system comprising a plurality of fans, the fans being single-speed fans, the plurality of the single-speed fans being arranged close to the cargo hold, and the plurality of the single-speed fans being electrically connected to the first switch and the second switch;

[0006] The first switch is used to be turned on when the ship is in a loading and unloading state, and the number of the single-speed fans electrically connected to the first switch is m; the second switch is used to be turned on when the ship is in a sailing state, and the number of the single-speed fans electrically connected to the second switch is n, m>n.

[0007] In this solution, the ventilation system uses a single-speed fan, which is set close to the cargo hold to meet the ventilation needs of the cargo hold. Multiple single-speed fans are electrically connected to a first switch and a second switch. The first switch is used to turn on when the ship is in a loading and unloading state to meet the ventilation needs in the loading and unloading state, and the second switch is used to turn on when the ship is in a sailing state to meet the ventilation needs in the sailing state. The number of single-speed fans electrically connected to the first switch is m, and the number of single-speed fans electrically connected to the second switch is n, m>n. Since goods need to be transported during loading and unloading, and the flow of people and vehicles is large, a larger ventilation volume is required. By setting m to be greater than n, the ventilation needs in the loading state can be met. The control system of the single-speed fan is simpler, the control cabinet size is smaller, and it is easier to arrange than the two-speed fan, which shortens the construction period. In addition, the single-speed fan uses fewer cables, saving construction costs.

[0008] Preferably, the ship further comprises a first deck and a second deck, the second deck is arranged above the first deck, and the plurality of single-speed fans are arranged on the first deck and the second deck.

[0009] In this solution, the ship includes a first deck and a second deck, the first deck and the second deck are at the same height, the second deck is arranged above the first deck, and a plurality of single-speed fans are arranged on the first deck and the second deck, so that the single-speed fans can be arranged on decks of different heights to meet ventilation needs at different heights.

[0011] In this scheme, there are usually more cargo holds on the deck below, the number of single-speed fans installed on the first deck is a, and the number of single-speed fans installed on the second deck is b. By setting a to be greater than b, the ventilation needs of the cargo holds can be better met.

[0012] Preferably, at least some of the single-speed fans are arranged at the bow and stern of the ship.

[0013] In this solution, by arranging at least part of the single-speed fans at the bow and stern of the ship, the ventilation effect of the bow and stern is improved, and the flow of air in the ship is strengthened.

[0014] Preferably, a plurality of the single-speed fans are arranged at the bow, stern and midship of the ship, the number of the single-speed fans arranged at the bow and stern of the ship is c, the number of the single-speed fans arranged at the midship of the ship is d, and c>d.

[0015] In this scheme, the number of single-speed fans installed at the bow and stern of the ship is c, and the number of single-speed fans installed at the midship of the ship is d. By setting c to be greater than d, the single-speed fans are arranged more dispersedly on the ship, thereby enhancing the flow effect of the airflow in the ship and improving the overall ventilation effect of the ship.

[0016] Preferably, the ventilation system further comprises air outlets, and a plurality of the air outlets are arranged in the midship of the ship.

[0017] In this solution, the air outlet is set in the middle of the ship, and most of the fans are set at the bow and stern of the ship, so that the distance between the single-speed fan and the air outlet is farther, the flow effect of the airflow in the ship is enhanced, and the overall ventilation effect of the ship is improved.

[0018] Preferably, the plurality of single-speed fans are arranged on both sides of the width direction of the ship;

[0019] The number of the single-speed fans located on the left side of the ship electrically connected to the first switch is at least one, and the number of the single-speed fans located on the right side of the ship electrically connected to the first switch is at least one.

[0020] In this solution, the number of single-speed fans located on the left and right sides of the ship electrically connected to the first switch is at least one, so that when the ship is in a loaded state, at least one single-speed fan on the left and right sides of the ship is turned on, thereby ensuring the ventilation effect of the ship in a loaded state.

[0021] Preferably, the plurality of single-speed fans are arranged on both side edges in the width direction of the ship.

[0022] In this solution, by arranging multiple single-speed fans on both side edges of the ship in the width direction, it is easier to introduce air from both sides of the ship into the interior of the ship, thereby improving the ventilation effect, optimizing the layout of the ship, and reducing the impact of single-speed fans on other equipment in the ship.

[0023] Preferably, a plurality of the single-speed fans are arranged at intervals along the length direction of the ship.

[0024] In this solution, by arranging single-speed fans at intervals along the length direction of the ship, the ship has a better ventilation effect in the length direction, thereby further improving the ventilation effect of the ship.

[0025] Preferably, a plurality of the single-speed fans are arranged on both sides of the cargo hold.

[0026] In this solution, by arranging single-speed fans on both sides of the cargo hold, the single-speed fans can fully ventilate the space in the cargo hold, thereby improving the ventilation effect in the cargo hold.

[0027] The positive and progressive effects of the present invention are:

[0028] The ventilation system uses a single-speed fan, which is set close to the cargo hold to meet the ventilation needs of the cargo hold. Multiple single-speed fans are electrically connected to the first switch and the second switch. The first switch is used to turn on when the ship is in the loading and unloading state to meet the ventilation needs in the loading and unloading state, and the second switch is used to turn on when the ship is in the sailing state to meet the ventilation needs in the sailing state. The number of single-speed fans electrically connected to the first switch is m, and the number of single-speed fans electrically connected to the second switch is n, m>n. Since goods need to be transported during the loading and unloading state, the flow of people and vehicles is large, so a larger ventilation volume is required. By setting m to be greater than n, the ventilation needs in the loading state can be met. The control system of the single-speed fan is simpler, the control cabinet size is smaller, and it is easier to arrange than the two-speed fan, which shortens the construction period. In addition, the single-speed fan uses fewer cables, saving construction costs. BRIEF DESCRIPTION OF THE DRAWINGS
