Description

Technical Field

[0001] The utility model relates to the technical field of ship air brake control, in particular to an electric watertight air brake control system for a ro-ro passenger ship. Background Art

[0002] Since there are a large number of spaces arranged at a lower position on a ro-ro passenger ship, all of which need to be ventilated, and these air ducts will inevitably pass through the watertight deck or watertight bulkhead, thus affecting the subdivision and damage stability, a large number of watertight air locks need to be arranged. However, the regulations have very few requirements for the control of watertight air locks, and many engineers face great doubts during the design process.

[0003] Compared with pneumatic and hydraulically driven watertight dampers, electric watertight dampers do not require the layout of compressed air pipes and hydraulic oil pipes. Their design and construction are relatively simple, so they are favored by engineers and are widely used. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a ro-ro passenger ship electric watertight air brake control system, which has high safety, simple system logic, convenient status monitoring and switch control of the watertight air brake, and low construction cost.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A control system for electric watertight dampers of a passenger and vehicle ferry, the passenger and vehicle ferry comprising a ventilation fan, the control system comprising a ventilation control box and a plurality of watertight dampers, the ventilation fan and the watertight damper bodies being connected by interlocking control of the ventilation control box, the ventilation control box being connected to the watertight dampers by cable communication, a damper control button being provided on the ventilation control box, and the ventilation control box controlling the opening and closing of the watertight dampers by the damper control button.

[0007] Furthermore, the control system also includes a wind gate hard wire board, which is communicatively connected to the ventilation control box via a hard wire, and a watertight wind gate group closing button for closing the watertight wind gate is provided on the wind gate hard wire board.

[0008] Furthermore, a limit switch is provided on the watertight damper for feeding back the switch status of the watertight damper and feeding back the status of the watertight damper to the ventilation control box.

[0009] Furthermore, the control system also includes an HVAC computer and an HVAC gateway. A PLC and a gateway are provided on the ventilation control box. The gateway on the ventilation control box is connected to the HVAC gateway via a network cable, and the HVAC computer and the HVAC gateway are connected via a network cable. The ventilation control box digitizes the status signals and control models of the fan and damper and transmits them to the HVAC computer via the HVAC gateway. The HVAC computer is used to control the opening and closing of the watertight damper.

[0010] Furthermore, a local control button for opening and closing the watertight damper is provided at one end of the cable between the ventilation control box and the watertight damper close to the watertight damper.

[0011] Furthermore, the watertight wind damper is a fail-closed watertight wind damper.

[0012] Furthermore, the ventilation control box is arranged on the freeboard deck.

[0013] Furthermore, the ventilation control box is connected to a main distribution board and an emergency distribution board.

[0014] The utility model provides an electric watertight airlock control system for a passenger and vehicle ro-ro ship. The watertight airlock is fail-closed, that is, it will automatically close when it loses driving power, so it has higher safety. When the cable providing power to the watertight airlock is cut off due to an accident causing water ingress, the watertight airlock will automatically close. A limit switch for feeding back the switch status of the watertight airlock is arranged on the watertight airlock, and the state of the watertight airlock is fed back to the ventilation control box. After the state signal of the watertight airlock enters the ventilation control box, it is fed back to the airlock hard-line board in the cab in the form of a hard line. In addition to displaying the switch status of the airlock, the airlock hard-line board is also provided with a group closing button for the watertight airlock. When water enters a certain place of the ship, the crew can quickly close all the watertight airlocks at this place in the cab. The local control button is arranged on the cable of the watertight airlock and the ventilation control box, and is arranged near the watertight airlock, so that the watertight airlock can be switched on and off on the spot.

[0015] The ventilation control box is a control box that controls the ventilation system including ventilation fans and dampers. It can realize the interlocking of fans and dampers. When the dampers are closed, the fans will automatically close or cannot be opened. It is equipped with PLC and gateway, which can digitize the status signals and control models of fans and dampers, and transmit them to HVAC computers through HVAC gateways, so that watertight dampers can be monitored not only in the ventilation control box, but also through HVAC computers;

[0016] The ventilation control box needs to be arranged on the freeboard deck so that it can work normally and be easily accessible when the ship is flooded. The ventilation control box has dual power supply from the main switchboard and the emergency switchboard, which better ensures the power supply of the ventilation control box.

[0017] The ventilation control box is arranged close to the watertight damper, and the damper hard wire board is in the cab, which is far away from the watertight damper. One watertight damper has only one set of limit switches. The status signal of the watertight damper must be transmitted to both the HVAC computer and the damper hard wire board. The ventilation control box processes the status signal of the watertight damper and can provide it to multiple users. In addition, one ventilation control box corresponds to many watertight dampers, and the ventilation control box can integrate the hard wires of these watertight dampers into one wire to the cab, thus reducing the number of cables.

[0018] The electric watertight damper control system of the ro-ro passenger ship of the utility model has high safety and is designed with redundancy. When an accident occurs, it is guaranteed to work normally to the greatest extent, including dual power supply of the ventilation control box, so that a single power failure will not cause the closure of the watertight damper, thereby affecting the normal operation of the ventilation system; when a water inflow accident occurs, it is guaranteed to be closed in time to the greatest extent, including local closure, closure of the ventilation control box arranged on the freeboard deck, closure in the HVAC control system, and closure of the hard line board in the cab; this new electric watertight damper control system for ro-ro passenger ships has a lower cost, and part of its control function is embedded in the HVAC control system of the ro-ro passenger ship, which ensures the function of the watertight damper in its ventilation system, reduces the cost, and reduces the number of control boxes.
