[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present application and its application or use.

[0027] Embodiment 1:

[0028] A telescopic fire water curtain applicable to ship fires, as shown in Figure 1 、 2 and 3, includes a water supply system and a spraying system. The water supply system is connected to the spraying system, and the spraying system is connected to a number of telescopic rods 12. The telescopic rods 12 are fixedly installed around the ship's hull. A fire detector 13 is provided on the ship's hull. The water supply system, the spraying system, the telescopic rods 12 and the fire detector 13 are connected to a fire control room 17. The spraying system includes a number of water supply branch pipes 11. An alarm valve group 7, a remote control signal valve 8 and a flow indicator 9 are provided on the water supply branch pipes 11. Water curtain sprinklers 14 are evenly distributed below the water supply branch pipes 11. The alarm valve group 7 and the remote control signal valve 8 are electrically connected to the fire control room 17 through electrical signals.

[0029] After the fire detector 13 detects a fire in the fishing port, the telescopic rod 12 is controlled to extend through the fire control room 17, and the water supply system is controlled to supply water to the spraying system. The remote control signal valve 8 and the alarm valve group 7 in the spraying system open the water curtain sprinklers 14 to spray water, wrapping the entire ship's hull in the fire water curtain. The spread of the fire in the fishing port can be effectively blocked by the fire water curtain generated by the present application, reducing the fire risk to the adjacent ships in the fire, and reducing the loss of life and property. In this embodiment, the ship's hull is specifically a fishing boat hull.

[0030] The electrical signal of the fire detector 13 is transmitted to the electrical fire control room 17. The electrical fire control, 17 uses an electrical fire linkage controller to control the telescopic movement of the ship's telescopic rod 12 and the startup of the water supply system and the spraying system respectively through weak electrical signals.

[0031] The water supply system includes a fire water tank 1, which is connected to a water supply main network 6. A fire water pump 4 is arranged at the front end of the water supply main network 6. An elastic seat sealing gate valve 2 is respectively arranged at the front and rear of the fire water pump 4. The water supply main network 6 is connected to the alarm valve group 7. The fire water pump 4 is controlled to start by the fire control room 17. The water in the fire water tank 1 is transported to the water supply main network 6. The alarm valve group 7 provides pressure for the pressure chamber through the control pipeline to realize the sealing of the valve disc and the valve body itself to control the water flow. After a fire occurs, the solenoid valve will be opened in conjunction to discharge the water in the control pipeline, reduce the pressure in the pressure chamber, and move the valve disc to the left to open. It can also be opened by a manual valve. The elastic seat sealing gate valve 2 controls the opening and closing of the pipeline to ensure that the water supply system is started in time when a fire occurs to supply water to the fire protection system. The alarm valve group 7 can be opened in two ways to reduce the possibility of affecting the operation of the entire fire protection system due to damage.

[0032] The front and rear ends of the fire pump are respectively connected to a vacuum pressure gauge 3 and a pressure gauge 5, the water supply main network 6 is connected to a water pump connector 16, and a Y-type filter 15 is arranged on the water supply main network 6. The vacuum pressure gauge 3 detects the water pump inlet pressure of the fire pump 4 suction pipe, and the pressure gauge 5 detects the water pump inlet pressure of the fire pump 4 outlet pipe. When a steel pipe whose inner wall is not treated with anti-corrosion coating is used, a Y-type filter 15 is required to be installed at the end of this section of the pipe, that is, before the inlet of the alarm valve. The vacuum pressure gauge 3 and the pressure gauge 5 are convenient for observing the pressure of the fire pump and for timely adjustment to ensure that the water supply main network 6 has sufficient water pressure.

[0033] The fire detector 13 includes an infrared thermoforming fire detector 13 , a smoke detector and a temperature detector to ensure the sensitivity of the fire detector 13 .

[0034] The water pump connector 16 is connected to the fire truck. When the fire water stored in the fire water tank is consumed, the fire truck can continue to provide fire water to the fire water curtain system through the water pump connector 16.

[0035] Embodiment 2:

[0036] Based on the first embodiment, a fire water curtain power supply implementation method is provided:

[0037] like Figure 1 As shown, the fire control room 17 and the fire water pump 4 are connected to a backup power supply or a power generation device 18.

[0038] What is different from the first embodiment is that in addition to the daily fire power supply, a separate backup power supply or power generation device 18 is set up. Solar photovoltaic panels and small wind turbines can be set up to reserve fire backup power supply, or a diesel generator can be set up as a fire water pump 4 power generation device to avoid the fire power supply used daily from failing to supply power normally and affecting the generation of the fire water curtain.

[0039] Embodiment III:

[0040] Based on Embodiment I, an implementation manner of a water supply system is provided:

[0041] The design flow rate of the fire pump 4 is determined according to the total flow rate of the water curtain nozzles 14 spraying water simultaneously within the action length at the most disadvantageous point. Refer to Figure 4 ;

[0042] In the formula: Q — System design flow rate (L / s);

[0043] qi — Flow rate of each nozzle node within the operation length at the most disadvantageous action point (L / min);

[0044] n — Number of sprinkler nozzles within the action length at the most disadvantageous point

[0045] The inlet water supply pressure of the water curtain system (design lift of the fire pump 4) shall be calculated according to the following formula: Refer to Figure 5 ;

[0046] In the formula: — Cumulative value of the head losses along the pipeline and local (MPa), and the local head loss of the alarm valve shall be determined according to the product sample or test data. When there is no such data above, the value of the water curtain alarm valve is taken as: 0.07 MPa;

[0047] P0 — Working pressure of the nozzle at the most disadvantageous point (MPa);

[0048] Z — Elevation difference (MPa) between the lowest water level of the fire fighting water tank or the horizontal center line of the pipe at the system inlet and the nozzle at the most disadvantageous point

[0049] A pressure reducing orifice plate 10 for ensuring the pressure balance at the inlet of the water supply branch pipe 11 is arranged above the water supply branch pipe 11.

[0050] Different from Embodiment I, according to the calculated system design flow rate and inlet water supply pressure of the fire pump 4, the situation of insufficient flow rate of the fire pump 4 or excessive water supply pressure affecting the operation of the entire device is reduced. The pressure reducing orifice plate 10 ensures the pressure balance at the inlet of the water supply branch pipe 11, restricts the inlet pressure of the water supply branch pipe 11, and reduces the inlet pressure.

[0051] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0052] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific circumstances.

[0053] The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
