Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:
A carrier vehicle with a liquefied natural gas leakage fire extinguishing device is shown in figures 1 and 2 and comprises a vehicle body 1, a liquefied natural gas tank 2, a water tank 3, a positioning rod 4, a gas pipe 5, a gas valve 6, a water mist pump 7, a detector 8 and at least two control switches 9.
The liquefied natural gas tank 2 is fixedly provided in a tank of the vehicle body 1. The water tank 3 is fixedly disposed in the tank of the vehicle body 1. The positioning rod 4 is fixedly arranged in a carriage of the vehicle body 1. One end and the liquefied natural gas jar 2 intercommunication, the other end setting of gas-supply pipe 5 are on locating lever 4, and when using the natural gas in the liquefied natural gas jar 2, only need install external pipeline on the gas-supply pipe 5 of locating lever 4, and this locating lever 4 has played the effect of location support. The air valve 6 is fixedly arranged at the other end of the air delivery pipe 5 and is used for controlling the natural gas to be closed. The water mist pump 7 is fixedly arranged in a carriage of the vehicle body 1, the water mist pump 7 is communicated with the water tank 3, and a nozzle of the water mist pump 7 is over against a port of the gas transmission pipe 5 and used for diluting the concentration of the natural gas. The water mist pump 7 adopts low pressure, and the system working pressure of the water mist pump 7 is not more than 1.20 MPa.
The detector 8 is fixedly arranged in a carriage of the vehicle body 1, the detector 8 is positioned on one side of the air valve 6 and used for detecting the concentration of the natural gas at the air valve 6 and transmitting a signal to the PLC in the control panel, and if the concentration of the natural gas detected by the detector 8 is greater than the set concentration, the PLC controls the water mist pump 7 to work to dilute the concentration of the natural gas. The air valve 6 adopts DA22Y-40P, the take-off pressure is less than 0.81MPa, and the recoil pressure is less than 0.77 MPa. The detector 8 employs a gas alarm controller of model RBK-6000-ZL60, which follows the national standard GB 16808-2008.
One of the control switches 9 is arranged in a cab of the vehicle body 1, the other control switch 9 is arranged outside a carriage of the vehicle body 1, and the plurality of control switches 9 are designed to facilitate operation. At this time, the detector 8 transmits the detected concentration information to the display, and if the concentration is greater than the set value, the control switch 9 can be manually operated to open or close the water mist pump 7, and the operation can be manually performed. The number of the control switches 9 is two, which is mainly for convenient operation, and if an operator is in the cab of the vehicle body 1, the operator can directly control the vehicle in a long distance; when the operator is outside the vehicle body 1, the water mist pump 7 can be controlled without entering the cab.
When the gas valve is used, although the gas valve 6 exists, a part of leaked natural gas is inevitably generated outside the gas transmission pipe 5, and when the concentration of the leaked natural gas is higher than a set value, the fine water mist can be sprayed by the fine water mist pump 7 to dilute the concentration of the natural gas, so that the risk of combustion and even explosion is reduced. Here, an alarm device may be provided together with the detector 8, and the alarm device is fixedly installed on the vehicle body 1, and makes a harsh sound when the concentration of the leaked natural gas is higher than a set value, thereby improving safety.
one end of the water delivery pipe 10 is communicated with the water tank 3, and the other end is placed at the opening of the carriage body 1. The water pipe 10 may be used for emergency treatment. Considering that water is also needed to close the water mist pump 7, the design adds another function at low cost.
In order to improve the effect of diluting the natural gas, the spraying direction of the port of the gas transmission pipe 5 and the spraying direction of the nozzle of the water mist pump 7 form an angle of 60 degrees, so that the natural gas can be conveniently sprayed to a high place; the distance between the spraying direction of the nozzle of the water mist pump 7 and the nozzle of the water mist pump 7 is 15 cm. And under the condition that the cloth obstructs an external pipeline, the safety is improved.
The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, and the embodiments should be regarded as being exemplary and non-limiting in any way whatsoever. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
