Description

Technical Field

[0001] The present invention relates to the technical field of preventing fire safety, and in particular to a fully automatic device for preventing the fire of a new energy vehicle on a roll-on / roll-off ship from spreading. Background Art

[0002] With the continuous development and maturity of electric vehicle technology, electric vehicles are gradually winning the favor of more and more customers, especially in countries with highly developed automobile markets such as China and Germany, where the demand for electric vehicles is showing a rapid growth trend. This increase in demand, especially the growth in the export of electric vehicles, has prompted a large number of electric vehicles to be transported by sea, especially relying on ro-ro ships for large-scale cross-border transportation. However, with the surge in the export volume of electric vehicles, the risk of fire has also increased significantly. During the transportation of ro-ro ships, fires caused by batteries in electric vehicles are very easy to spread. If they are not controlled in time, they may cause serious accidents, pose a great threat to the safety of the crew and passengers, and even cause huge property losses.

[0003] Battery fires on ro-ro ships currently in use have significant characteristics when transporting electric vehicles. First, once a battery catches fire, it burns very quickly, the temperature rises rapidly, and the fire is difficult to control. In addition, battery fires are extremely difficult to extinguish, and traditional fire-fighting methods often cannot effectively suppress the combustion inside the battery. This is because the structure of the ro-ro ship limits fire prevention and control measures, and the fire isolation measures for electric vehicles in the cabin are not perfect. Once the fire source is out of control, the fire is likely to spread rapidly, and may even affect the entire ship, expanding the scope of the disaster.

[0004] To complicate matters further, conventional firefighting equipment has difficulty penetrating the battery area at the bottom of electric vehicles, which is precisely the high-incidence zone of fire. The hidden and difficult-to-access location of the batteries, coupled with the closed nature of the vehicle body, makes it difficult for rescuers to carry out firefighting operations in a timely manner, resulting in low efficiency in firefighting. In addition, the high temperature of battery fires makes it difficult for ordinary firefighting equipment to cope with it, and sometimes even if the open fire is extinguished briefly, there is a risk of re-ignition. Therefore, in this context, it is particularly important to design and propose a fully automated device aimed at preventing the rapid spread of electric vehicle fires during RoRo transportation. Summary of the invention

[0005] According to the technical problems mentioned in the above background technology, a fully automatic device for preventing the spread of fire in new energy vehicles on ro-ro ships is provided. The present invention is used to effectively prevent the rapid spread of fire in the process of transporting new energy vehicles on ro-ro ships. The device is intended to solve many problems in the prior art, including the limitations of existing fire isolation measures, and once a battery fire occurs, the fire can easily spread to surrounding vehicles, eventually causing the risk of the entire ship being caught in fire. Especially during the transportation of ro-ro ships, due to the limitations of the hull structure and parking space layout, traditional water-based fire-fighting equipment cannot be directly and effectively sprayed onto the battery part of the electric vehicle for fire extinguishing. Once the battery fire is impacted by water, it may also cause the side effect of water decomposition to produce hydrogen, which greatly increases the risk of explosion and further aggravates the difficulty of fire extinguishing.

[0006] The technical means adopted by the present invention are as follows:

[0007] A fully automatic device for preventing the spread of fire in a new energy vehicle of a roll-on / roll-off ship comprises: a support module, a thrust module, a fireproof cloth, a control module and a firefighting module; the support module comprises: a front support unit, a rear support unit, a trapezoidal connecting frame and a connecting rod; the front support unit and the rear support unit have the same structure and are symmetrically arranged, each of the support units comprises 4 brackets, the trapezoidal connecting frame is fixedly connected to the parking space, and each bracket is mounted on the trapezoidal connecting frame; the thrust module comprises: a main hydraulic cylinder and a secondary hydraulic cylinder; the thrust module is arranged on each bracket; the fireproof cloth is sleeved on each bracket through a cloth sleeve; the control module comprises: a temperature sensor, an electromagnet and a controller; the temperature sensor is fixedly mounted on each bracket; the electromagnet is fixedly mounted on the trapezoidal connecting frame on the inner side of the fireproof device; the controller is fixedly mounted on the top of the cabin; the firefighting module comprises: a fire sprinkler and a fire alarm; the fire sprinkler and the fire alarm are fixedly mounted on a base on the top of the cabin.

[0008] Furthermore, the trapezoidal connecting frame of the front supporting unit and the rear supporting unit is fixedly installed on the parking space through connecting rods, and the brackets of each supporting unit are the first bracket, the second bracket, the third bracket and the fourth bracket from the inside to the outside; the first bracket is fixedly connected to the trapezoidal connecting frame, and the second bracket, the third bracket and the fourth bracket are movably connected to the trapezoidal connecting frame through bolts, and the bolts are linearly arranged along the hypotenuse of the trapezoidal connecting frame.

[0009] Furthermore, the main hydraulic cylinder and the auxiliary hydraulic cylinder both include: a hydraulic rod and a hydraulic cylinder sleeve; the hydraulic rod of the main hydraulic cylinder is movably connected to the fourth bracket by bolts, the hydraulic cylinder sleeve of the main hydraulic cylinder is movably connected to the second bracket by bolts, the hydraulic rod of the auxiliary hydraulic cylinder is movably connected to the third bracket by bolts, and the hydraulic cylinder sleeve of the auxiliary hydraulic cylinder is movably connected to the first bracket by bolts.

[0010] Furthermore, the main hydraulic cylinder and the auxiliary hydraulic cylinder calculate the length of the hydraulic rod and the hydraulic cylinder sleeve according to the distance after the bracket is folded and unfolded.

[0011] Furthermore, the fireproof cloth is slidably connected to the bracket via a cloth cover.

[0012] Furthermore, the temperature sensor is fixedly installed on the inner side of the device and distributed on the top and both sides of each bracket; the electromagnet is fixedly installed on each inner trapezoidal connecting frame, the top rod of the electromagnet is in contact with the hydraulic rod, and the hydraulic rod is magnetically attracted when powered and released when powered off; the controller is fixedly installed on the top of the cabin.

[0013] Furthermore, the fire sprinklers and fire alarms are linearly distributed on the base.

[0014] Furthermore, the temperature sensor detects the ambient temperature of the new energy vehicle. When the preset temperature is reached, the temperature signal is converted into an electrical signal and transmitted to the controller. The controller sends instructions to the electromagnet, fire sprinkler and fire alarm. After receiving the instruction, the electromagnet loses power, releases the hydraulic rod, drives the bracket and the fireproof cloth to unfold, forms a closed vehicle cover, prevents the fire from spreading, and at the same time, the opened fire sprinkler sprays water to cool the fireproof cloth.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] After the electromagnet of the device of the present invention loses power, the front support unit and the rear support unit rotate around the bolt to the front and rear sides of the vehicle with a swift movement under the instantaneous push of the hydraulic rod. In this process, the front support unit and the rear support unit cooperate with each other to form a completely enclosed vehicle cover structure, which completely covers the entire vehicle body. This enclosed vehicle cover can not only effectively block the flow of external air, but also prevent the thick smoke and open flames generated by the fire from further spreading, thereby playing a role in controlling the fire source. At the same time, the fire sprinkler equipment on the top of the vehicle cover starts to work automatically, and the temperature of the vehicle body is quickly reduced by continuously spraying water mist on the surface of the vehicle cover. This process can not only effectively cool the vehicle body, but also greatly enhance the efficiency of fire extinguishing, thereby avoiding the spread and re-ignition of the fire caused by high temperature. The operation of the entire device is fully automated, without the need for manual intervention, which not only improves the convenience and efficiency of operation, but also significantly reduces the risk of personnel approaching the fire source, making the fire extinguishing process safer and more reliable.
