Description

Technical Field

[0001] The utility model relates to the technical field of natural gas storage and transportation, in particular to an anti-collision structure for natural gas storage and transportation. Background Art

[0002] Natural gas has good environmental protection characteristics, low cost of use, and high calorific value. With the favor of the majority of users and the support of the country, it has quickly occupied a place in the energy market industry and is showing a trend of expanding the Chinese market and booming. However, in terms of natural gas liquefaction, storage and transportation, although my country currently has relatively complete technology, from the perspective of natural gas liquefaction development, in order to ensure the safety of natural gas liquefaction, storage, transportation and use, it is still necessary to strengthen the research on natural gas liquefaction technology and storage and transportation safety.

[0003] At present, an existing liquefied natural gas storage and transportation tank (such as patent number: CN211371908U) discloses a liquefied natural gas storage and transportation tank, including a shell, an exhaust pipe and an alarm, an opening is opened on one side of the shell, and the shell on the side of the opening is fixedly connected to an end cover by a flange and bolts, a base is fixedly connected to the middle of the lower surface of the shell near both ends by bolts, and a pressure gauge is fixedly connected to the middle of one side of the shell near one end by bolts; the utility model is provided with an alarm, contacts and an insulating plate, when the water stop expands when encountering water, the insulating plate can be pushed outward, so that the contacts on one side of the two insulating plates are close to each other until they are squeezed and contacted with each other, so that the battery, the alarm and the two contacts form a closed loop, and an alarm sound is issued to remind the transportation personnel that a leakage has occurred. If the leakage cannot be handled in time, the water stop can expand when encountering water, completely block the leakage point, prevent the liquefied natural gas from leaking to the outside, prevent the occurrence of explosion, and ensure the safety of personnel.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the existing storage and transportation tanks are transported by vehicles or ships, the natural gas tank body is easily impacted during transportation, which can easily cause natural gas leakage in the tank body. When the natural gas leaks, the alarm is used to remind the transportation personnel. However, the alarm function after the impact leakage cannot avoid damage to the tank body after the impact occurs. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides an anti-collision structure for natural gas storage and use, which solves the problem that when existing storage and transportation tanks are transported by vehicles or ships, the natural gas tank body is easily impacted during transportation, which can easily lead to natural gas leakage in the tank body. When natural gas leaks, the transportation personnel are reminded by the alarm of the alarm device. However, the structure has an alarm function after impact and leakage but cannot avoid the technical problem that the tank body is damaged after the impact.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A natural gas storage and utilization anti-collision structure comprises a storage and transportation tank, a front guard plate is fixedly installed on the side end of the storage and transportation tank, and a rear guard plate is fixedly installed on the side end of the storage and transportation tank; a protruding storage plate is provided on the side end of the front guard plate, and two storage boxes are symmetrically fixedly installed on both sides of the front guard plate, and an air intake pipe is fixedly installed on the bottom end of the two storage boxes; the two storage boxes are both located between the front guard plate and the rear guard plate, and a first air bag is slidably installed on the side end of the front guard plate, and a first cover plate is fixedly installed on the top end of the first air bag; the bottom end of the first air bag is connected with the air intake pipe, a second air bag is slidably installed on the side end of the front guard plate, and a second cover plate is fixedly installed on the top end of the second air bag; the bottom end of the second air bag is connected with the air intake pipe, an air pump is fixedly installed on the side end of the front guard plate, and a three-way pipe is fixedly installed on the top end of the air pump, a first elbow pipe is fixedly installed on the side end of the three-way pipe, and a second elbow pipe is fixedly installed on the side end of the three-way pipe; the first elbow pipe and the second elbow pipe are respectively connected with the two air intake pipes.

[0010] Preferably, two front hanging holes are symmetrically provided on the top of the front guard plate.

[0011] Preferably: two rear hanging holes are symmetrically provided on the top of the rear guard plate.

[0012] (III) Beneficial effects

[0013] 1. The front hoisting holes and the rear hoisting holes at the top of the front guard plate and the rear guard plate can be used for hoisting connection during transportation. Before transportation, the air pump is started, and the air pump pumps air into the first elbow and the second elbow through the three-way pipe, and then enters the two air inlet pipes through the first elbow and the second elbow, and finally the first airbag and the second airbag are inflated. The inflated first airbag and the second airbag will slowly expand, and the first cover plate and the second cover plate will be lifted upward, so that the first cover plate and the second cover plate slide along the guide grooves at both ends of the front guard plate and the rear guard plate to wrap and protect the storage tank in the middle. When the first airbag and the second airbag filled with air are hit, the air inside them can be compressed, and the kinetic energy brought by the impact can be converted into the internal energy of the air to complete the absorption of the kinetic energy, thereby preventing the storage tank from being punctured, causing the natural gas inside it to leak. By inflating the first airbag and the second airbag, the storage tank is wrapped, and the effect of effectively preventing the storage tank from being punctured due to the impact and leaking natural gas is achieved.

[0014] 2. During use, since the first airbag and the second airbag are filled with air, they are light in weight and do not require more transportation capacity due to the anti-collision structure. When not in use, the air pump is started to draw the air inside the first airbag and the second airbag along the second bend pipe, the first bend pipe, and the three-way pipe. Since the air inside the first airbag and the second airbag is reduced, under the action of atmospheric pressure, the first airbag and the second airbag will pull the first cover plate and the second cover plate back into the storage box to complete the storage, making it convenient for operators to add and discharge natural gas. The storage is completed by discharging the air inside the first airbag and the second airbag, thereby achieving the effect of easy storage and convenient operation.

[0021] The embodiment of the present application provides a natural gas storage and use anti-collision structure, which effectively solves the existing storage and transportation tanks. When transported by car or ship, the natural gas tank body is easily impacted during the transportation process, which can easily cause natural gas leakage in the tank body. When natural gas leaks, the transportation personnel are reminded by the alarm of the alarm device. The alarm function after the impact leakage cannot avoid the technical problem that the tank body is damaged after the impact. The front hoisting hole and the rear hoisting hole on the top of the front guard plate and the rear guard plate can be used for hoisting connection during transportation. Before transportation, the air pump is started, and the air pump pumps air into the first bend pipe and the second bend pipe through the three-way pipe, and then enters the two air inlet pipes through the first bend pipe and the second bend pipe. Finally, the first airbag and the second airbag are inflated. The inflated first airbag and the second airbag will slowly expand, and the first cover plate and the second cover plate are lifted up, so that the first cover plate and the second cover plate slide along the guide grooves at both ends of the front guard plate and the rear guard plate, and the storage and transportation tank in the middle is wrapped and protected. The first airbag and the second airbag filled with air will be When the first and second airbags are hit, the air inside them can be compressed, and the kinetic energy brought by the impact can be converted into the internal energy of the air, so as to complete the absorption of the kinetic energy, thereby preventing the storage tank from being punctured and causing the natural gas inside to leak. By inflating the first and second airbags, the storage tank is wrapped, which can effectively prevent the storage tank from being punctured due to the impact and causing the leakage of natural gas. During use, since the first and second airbags are filled with air, the weight is relatively light, and no more transportation capacity is required due to the anti-collision structure during transportation. When not in use, the air pump is started to extract the air inside the first and second airbags along the second elbow, the first elbow, and the three-way pipe. Due to the reduction of air inside the first and second airbags, under the action of atmospheric pressure, the first and second airbags will pull the first cover plate and the second cover plate back into the storage box to complete the storage, which is convenient for operators to add and discharge natural gas. The storage is completed by discharging the air inside the first and second airbags, which achieves the effect of easy storage and convenient operation.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the existing storage and transportation tanks. When transported by car or ship, the natural gas tank body is easily hit during transportation, which can easily cause natural gas leakage in the tank body. When natural gas leaks, the alarm of the alarm device is used to remind the transport personnel. The alarm function after the impact leakage cannot avoid the technical problem that the tank body is damaged after the impact. The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides an anti-collision structure for natural gas storage and use, including a storage tank 1, a front guard plate 2 is fixedly installed on the side end of the storage tank 1, and a rear guard plate 13 is fixedly installed on the side end of the storage tank 1; a protruding storage plate is provided on the side end of the front guard plate 2, and two storage boxes 3 are symmetrically fixedly installed on both sides of the front guard plate 2, and an air intake pipe 12 is fixedly installed on the bottom end of the two storage boxes 3.

[0025] The two storage boxes 3 are both located between the front guard plate 2 and the rear guard plate 13. The first airbag 4 is slidably installed on the side end of the front guard plate 2, and the first cover plate 5 is fixedly installed on the top of the first airbag 4; the bottom end of the first airbag 4 is connected to the air intake pipe 12, and the second airbag 14 is slidably installed on the side end of the front guard plate 2, and the second cover plate 15 is fixedly installed on the top of the second airbag 14; the bottom end of the second airbag 14 is connected to the air intake pipe 12.

[0026] An air pump 6 is fixedly installed on the side end of the front guard plate 2, a three-way pipe 7 is fixedly installed on the top of the air pump 6, a first elbow 8 is fixedly installed on the side end of the three-way pipe 7, and a second elbow 9 is fixedly installed on the side end of the three-way pipe 7; the first elbow 8 and the second elbow 9 are respectively connected to two air intake pipes 12, two front hanging holes 11 are symmetrically opened on the top of the front guard plate 2, and two rear hanging holes 16 are symmetrically opened on the top of the rear guard plate 13.

[0027] Working principle:

[0028] In the first step, the front hoisting holes 11 and the rear hoisting holes 16 opened at the top of the front guard plate 2 and the rear guard plate 13 can be used for hoisting connection during transportation. Before transportation, start the air pump 6, and the air pump 6 pumps air into the first elbow 8 and the second elbow 9 through the three-way pipe 7, and then enters the two air inlet pipes 12 through the first elbow 8 and the second elbow 9. Finally, the first airbag 4 and the second airbag 14 are inflated. The inflated first airbag 4 and the second airbag 14 will slowly expand, and the first cover plate 5 and the second cover plate 15 are pushed up, so that the first cover plate 5 and the second cover plate 1 5 slides along the guide grooves at both ends of the front guard plate 2 and the rear guard plate 13 to wrap and protect the storage tank 1 in the middle. When the first airbag 4 and the second airbag 14 are impacted, they can compress the air inside them and convert the kinetic energy brought by the impact into the internal energy of the air to absorb the kinetic energy, thereby preventing the storage tank 1 from being punctured and causing the natural gas inside to leak. By inflating the first airbag 4 and the second airbag 14 to wrap the storage tank 1, the effect of effectively preventing the storage tank 1 from being punctured due to impact and causing natural gas leakage is achieved.

[0029] The second step is that during use, since the first airbag 4 and the second airbag 14 are filled with air, they are light in weight and do not require more transportation capacity due to the anti-collision structure. When not in use, the air pump 6 is started to extract the air inside the first airbag 4 and the second airbag 14 along the second bend pipe 9, the first bend pipe 8, and the three-way pipe 7. Since the air inside the first airbag 4 and the second airbag 14 is reduced, under the action of atmospheric pressure, the first airbag 4 and the second airbag 14 will pull the first cover plate 5 and the second cover plate 15 back into the storage box 3 to complete the storage, making it convenient for the operator to add and discharge natural gas. The storage is completed by discharging the air inside the first airbag 4 and the second airbag 14, thereby achieving the effect of easy storage and convenient operation.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
