[0025] Specifically, the shape of the skid-mounted equipment body 1 is not fixed. The commonly used multi-functional emergency gas source guarantee device is a vehicle-mounted box type at present, so the skid-mounted equipment body 1 is in the shape of a carriage. The carriage has a total of 4 sides. Generally, the last side of the carriage is used as the opening of the skid-mounted equipment body 1 to facilitate the subsequent installation and fixation of the integrated module 15 for emergency gas source guarantee; therefore, the whole of this embodiment adopts a vehicle-mounted mobile skid-mounted type and uses LNG as the gas source for emergency gas supply.

[0026] Fixed brackets 11 are installed at the 4 corners of the carriage, and a protective plate 12 is installed between the fixed brackets 11. Here, the length and height of the protective plate 12 can be adjusted according to the load-bearing adaptability of the corresponding equipment of the integrated module. In this way, the 4 protective plates 12 enclose to form a skid-mounted integrated tank 13, and the integrated module 15 for emergency gas source guarantee is fixedly integrated in the skid-mounted integrated tank 13. Based on the integrated module, it has the characteristics of multi-functional integration, small volume, compact structure, fast gas supply, simple operation, high degree of automation, adjustable outlet pressure, and automatic switching of the gas supply circuit, etc.

[0027] A positioning component 14 is vertically installed in the skid-mounted integrated tank 13 along the length direction of the protective plate 12, and the integrated module 15 is adaptively assembled based on the positioning component 14; AsFigure 3 As shown, the positioning component 14 includes a connection substrate 1401 provided with a guiding component.

[0028] One end of the connection substrate 1401 is fixed on the protective plate 12 through a fixing seat 1402, and a telescopic pipeline connection end 1404 is installed on the fixing seat 1402; the other end of the connection substrate 1401 is fixedly connected to the corresponding protective plate 12 on the other side through a clamping component 1403.

[0029] Embodiment 2

[0030] For the parts not detailed in the present utility model, please refer to Figure 4 , the integrated module 15 is mainly a multifunctional module for realizing emergency gas source guarantee. The waste gas generated during the operation of the multifunctional module is discharged through the air outlet pipe 1507. The multifunctional integrated module is used to realize the configuration of more application scenarios, specifically as follows:

[0031] The integrated module 15 includes an LNG storage tank 1501. The LNG storage tank 1501 transports liquid LNG to the vaporizer 1502 through pipeline valves. The vaporizer 1502 heats the LNG by using the heat of the surrounding environment or an external heating source through a heat exchanger to evaporate it into gaseous LNG, realizing the gasification process; the gaseous LNG adjusts the pressure through a pressure regulator 1503 to make the output natural gas pressure stable within the required range to meet the needs of downstream users. When the pressure regulator 1503 unloads the gaseous LNG from the transport vehicle to the storage facility through a truck unloading booster pump 1504, it enables smooth transmission and unloading; and monitoring elements are provided at the conveying pipelines 1506 for transmission on the LNG storage tank 1501, vaporizer 1502, heat exchanger, pressure regulator 1503, and truck unloading booster pump 1504. The monitoring elements are connected to a chain controller 1505 to control the operating state of the entire device based on the chain controller 1505, including automatically switching the gas supply circuit, automatically adjusting the pressure, temperature, etc., and processing various signals and warnings.

[0032] Specifically, the integrated module 15 further includes auxiliary pipeline valves, detection instruments and control elements added to the conveying pipeline 1506. The integrated module 15 is integrated into the skid-mounted equipment body 1, which facilitates the rapid deployment, movement and installation of the integrated module 15. Through high automation and integration, it can achieve rapid and reliable supply of natural gas in case of emergency, thereby reducing human intervention and improving the safety and stability of gas supply. At the same time, functions such as gasification, heat exchange and pressure stabilization are integrated into a skid-mounted equipment, making the equipment have good mobility and adaptability and being able to adapt to different usage scenarios and requirements.

[0033] In addition, it should be noted that the integrated module 15 further includes an odorization module, a lighting module, a leakage alarm module and an over-limit shutdown module.

[0034] Embodiment 3

[0035] The parts not described in detail in the present utility model are as shown in Embodiment 1. Based on the cooperation of the skid-mounted integrated tank 13 and the positioning component 14, an integrated cavity 100 is formed. A hose storage cavity 200 is formed at the top of the integrated cavity 100 by installing a hose storage rack. The gas outlet pipe passes through the hose storage cavity 200 and extends out. A buffer cavity 300 is arranged at the bottom of the integrated cavity 100. A horizontally laid U-shaped drainage channel is arranged inside the buffer cavity 300. The water outlet of the drainage channel is arranged at the fixed bracket 11, and a water collecting cavity is arranged at the bottom of the fixed bracket 11. The water collecting cavity communicates with the outside to directly discharge the waste water. Since the waste water generated in the multifunctional emergency gas source guarantee device is due to the natural reaction of heat and cold alternation, the waste water can be directly discharged without adding a waste water recovery device. Of course, if there are harmful substances in the use environment, a waste water treatment device can be directly added to the water collecting cavity or the waste water can be recycled.

[0036] Specifically, a hose storage rack is arranged inside the hose storage cavity 200, which can place hoses and adapters, fix the hoses, facilitate access and temporary replacement. Of course, common explosion-proof tools, low-temperature labor protection supplies, common gaskets, etc. can also be placed. The gas emergency gas source guarantee is equipped with: two sets of connecting pipes of three models of stainless steel metal hoses DN50\DN40\DN25 at the inlet, and stainless steel metal hoses of DN50 / DN50 model at the outlet, and a variety of flange-type adapters at both ends are configured: DN50 / DN150, DN50 / DN125, DN50 / DN100, DN50 / DN80, one end is connected to the hose, and the other end is connected to the on-site equipment to adapt to a variety of scenarios.
