Description

Technical Field

[0001] The utility model belongs to the technical field of special equipment, and in particular relates to a military shelter. Background Art

[0002] Military shelters are compartments that carry military equipment and personnel and provide the required working conditions and environmental protection. They are suitable for use as carriers and workrooms for weapon systems, command and communication centers, technical support and logistics equipment, and various types of military equipment and personnel. They are widely used in command, control, reconnaissance, detection, communication, electronic countermeasures, rescue, service operations, camping life, and other scenarios.

[0003] In order to adapt to the complex and diverse use environment, the technology of military shelters is constantly innovating. For example, the patent document with the announcement number CN211081130U discloses a military shelter, which includes a box body, which is a container-type structure. The front, back, left, right and top of the box body are all provided with supporting steel plates and rock wool insulation layers. A single door is provided on one side of the box body, and a power supply and network port for connecting to the outside is provided on one side of the single door. There are windows on the other side of the box body, and bulletproof and smash-proof glass is provided on the window. A set of roller curtains is provided above the window. Tables and lockers are provided on both sides of the shelter, and power and network socket combinations are provided above the table on both sides. Nylon tightening belts for fixing folding chairs are provided below the table on both sides. LED ceiling lights and light control switches are also provided on the top of the box body. However, after careful analysis by the inventor, it was found that the military shelter with this structure still has the following technical problems:

[0004] 1. The shelter uses a whole steel plate as the supporting structure, and a rock wool insulation layer is directly set on the inner surface of the steel plate, which not only makes the overall weight of the shelter heavier, but also makes the inner surface of the shelter easily damaged.

[0005] 2. The cabin door was not sealed and electromagnetically shielded, which not only resulted in poor overall sealing of the cabin, but also made it vulnerable to interference from electromagnetic signals outside the cabin.

[0006] 3. The four supporting steel plates at the front, back, left and right of the shelter are usually single plates, but the fixing structure at the corners of the supporting steel plates is not limited, resulting in poor fixing effect, easy leakage and poor sealing effect.

[0007] 4. The cabin has not undergone anti-corrosion treatment, which makes it unsuitable for use in island environments with high humidity and high salt fog, and therefore its scope of application is relatively narrow. Utility Model Content

[0008] The purpose of the utility model is to overcome the above-mentioned technical problems existing in the prior art and provide a military shelter, which adopts a specific cabin structure mainly composed of a square tube support frame, inner and outer corrosion-resistant aluminum skins, etc., which can not only reduce the weight of the shelter while ensuring that the shelter has a high structural strength, but also improve the overall sealing performance and anti-electromagnetic interference performance of the shelter, and solve the technical problems of the existing shelter being heavy in overall weight, poor in sealing and easily affected by electromagnetic signals outside the cabin.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0010] A military square cabin comprises a cabin body and a cabin top and a cabin bottom sealed and fixed at the upper and lower ends of the cabin body, the cabin body comprises a support frame, a flame retardant material, an outer skin and an inner skin both made of corrosion-resistant aluminum material, the number of the support frames is four groups and they are arranged in a rectangular shape, the (left and right) ends of each group of support frames are respectively vertical support square tubes, the edges of the two vertical support square tubes between two adjacent groups of support frames are in contact, and the two adjacent vertical support square tubes are respectively fixed by an outer L-shaped corner code and an inner L-shaped corner code; the outer skin is fixedly wrapped on the outer side of the four groups of support frames and forms the outer side surface of the cabin body, and at least two adjacent outer side surfaces share the same outer skin; the inner skin is fixed on the inner side of the four groups of support frames by an inner L-shaped corner code and forms the inner side surface of the cabin body, and at least two adjacent inner side surfaces share the same inner skin; the flame retardant material is filled between the outer skin and the inner skin; a cabin door is fixed on the cabin body, and a water vapor sealing strip and an electromagnetic shielding sealing strip are arranged between the door frame and the door body of the cabin door.

[0011] The four corners of the cabin body are fixed with outer corners covering the outer skin through support frames.

[0012] The water vapor sealing strip is fixed in the sealing groove of the door body, and the electromagnetic shielding sealing strip is respectively fixed in the sealing groove of the door frame and the sealing groove of the door body.

[0013] Metal glue is provided between the support frame and the outer skin and between the support frame and the inner skin.

[0014] The cabin top and cabin bottom are both fixed by a support frame, an outer skin, an inner skin and a flame retardant material, and outer wrap angles are fixed between the cabin top and the cabin body and between the cabin bottom and the cabin body.

[0015] Upper corner pieces are fixed at the four corners of the cabin body and the cabin top, and lower corner pieces are fixed at the four corners of the cabin body and the cabin bottom.

[0031] The military shelter described in the utility model has been successfully developed and trial samples have been produced. The applicant has tried it and found that it has the technical effects of light weight, simple preparation process, good sealing performance and good anti-electromagnetic interference performance. In order to better protect this technology, the applicant has filed a utility model patent application for the technology. The utility model is described in detail below in conjunction with specific embodiments.

[0032] The utility model provides a military shelter, such as Figure 1-2 As shown, the military shelter includes a cabin body 1, a cabin roof 2 and a cabin bottom 3. The cabin body 1 is a cubic structure including four sides. The cabin roof 2 and the cabin bottom 3 are sealed and fixed at the upper and lower ends of the cabin body 1 respectively.

[0033] like Figure 1-4 As shown, the cabin 1 includes four groups of support frames arranged in a rectangular shape, the left and right ends of each group of support frames are respectively vertical support square tubes 5, and the upper and lower ends of each group of support frames can be respectively two horizontal support square tubes. Between two adjacent groups of support frames, the edges of the two vertical support square tubes 5 are in contact, and the outer sides between the two adjacent vertical support square tubes 5 are fixed by outer L-shaped corner brackets 9 and rivets, and the inner sides between the two adjacent vertical support square tubes 5 are fixed by inner L-shaped corner brackets 10 and rivets. Specifically, Figure 4 Taking the direction shown as an example, assuming that the vertical supporting square tubes 5 located at the top and bottom are the square tubes A and B of two adjacent groups of supporting frames, the right side and lower side of the square tube A are respectively perpendicular to the upper side and left side of the square tube B, the two sides of the outer L-shaped corner bracket 9 are respectively fixed to the lower side of the square tube A and the left side of the square tube B by rivets, and the two sides of the inner L-shaped corner bracket 10 are respectively fixed to the right side of the square tube A and the upper side of the square tube B by rivets. Since the cabin 1 adopts this specific supporting frame structure, it can ensure that the cabin has sufficient bearing capacity.

[0034] Furthermore, outer corners 15 covering the outer skin 6 are fixed at the four corners of the cabin 1, and each outer corner 15 is fixed to two adjacent groups of support frames by rivets, so as to improve the structural strength of the outer skin 6 at the corners and protect the outer skin 6.

[0035] like Figure 1-4 As shown, the cabin 1 also includes an outer skin 6 and an inner skin 7, both of which are made of corrosion-resistant aluminum. The outer skin 6 and the inner skin 7 can be made of 3A21 rust-resistant aluminum. The outer skin 6 can be fixedly wrapped on the outside of the four groups of support frames by metal glue and form the outer side of the cabin 1. The inner skin 7 can be fixed on the inner side of the four groups of support frames by metal glue and form the inner side of the cabin 1. It can not only improve the fixing effect of the outer skin 6 and the inner skin 7 on the support frame, but also effectively avoid direct contact between the two metals. In addition, in order to improve the sealing between the two vertical supporting square tubes 5 as much as possible, at least two adjacent outer sides share the same outer skin 6, and at least two adjacent inner sides share the same inner skin 7, that is, a complete inner skin 7 and an outer skin 6 are used to encapsulate the two vertical supporting square tubes 5 of the two adjacent groups of support frames; of course, according to actual needs, the outer skin 6 and the inner skin 7 in the cabin 1 can also be one.

[0036] It should be noted that if Figure 4 As shown, the inner skin 7 is located between the inner L-shaped angle bracket 10 and the support frame, and the inner skin 7 is also fixed to the support frame by the inner L-shaped angle bracket 10 and rivets, thereby ensuring that the relative position relationship between the two side surfaces of the cabin 1 is stable and secure.

[0037] like Figure 3-4 As shown, the cabin 1 also includes a flame retardant material 8, which is filled between the outer skin 6 and the inner skin 7. Specifically, a lightweight flame retardant foam can be used as the flame retardant material 8, which not only enhances the integrity and reliability of the cabin 1, but also has a good heat insulation function, which is conducive to maintaining a constant temperature in the cabin.

[0038] like Figure 1As shown, a hatch 4 is fixed on the cabin 1. The hatch 4 also adopts a structure in which the outer skin 6 and the inner skin 7 clamp the support frame and fill the flame retardant material 8, so as to be consistent with the material and structure of the cabin 1. The hatch 4 includes a door frame 11 and a door body 12. In order to ensure that the door frame 11 and the door body 12 have good sealing when closed, this solution adopts a two-level sealing method, that is, a water vapor sealing strip 13 and an electromagnetic shielding sealing strip 14 are installed between the door frame 11 and the door body 12. Among them, the water vapor sealing strip 13 is fixed in the sealing groove of the door body 12, and the electromagnetic shielding sealing strip 14 is fixed in the sealing groove of the door frame 11 and the sealing groove of the door body 12 respectively. The water vapor sealing strip 13 is the first layer of sealing measures, which is mainly used to prevent water vapor and dust outside the cabin from penetrating into the cabin; the electromagnetic shielding sealing strip 14 is the second layer of sealing measures. In addition to having waterproof and dustproof functions, it can also effectively block the interference of electromagnetic signals outside the cabin, thereby protecting the equipment in the cabin from the influence of electromagnetic radiation.

[0039] like Figure 1 As shown, the cabin roof 2 and the cabin bottom 3 are both fixed by a support frame, an outer skin 6, an inner skin 7 and a flame retardant material 8, and outer corners 15 are fixed at the four sides between the cabin roof 2 and the cabin body 1 and at the four sides between the cabin bottom 3 and the cabin body 1, upper corner pieces 16 are fixed at the four corners of the cabin body 1 and the cabin roof 2, and lower corner pieces 17 are fixed at the four corners of the cabin body 1 and the cabin bottom 3.

[0040] In order to further optimize the working environment in the cabin, extend the service life of the equipment in the cabin, and improve the comfort of the operators, it is necessary to effectively control the temperature, humidity, and salt spray level of the air in the cabin. Figure 1-2 As shown, the utility model has a desalting mist machine 18 fixed at the lower part of the cabin 1, and an air conditioner 19 and an air conditioner main unit are fixed on the outer side and inner side of the upper part of the cabin 1, respectively. A plurality of vents 20 connected to the air conditioner main unit are provided on the inner side of the upper part of the cabin 1. The temperature and humidity of the air in the cabin are adjusted by the cooperation between the air conditioner and the vents 20. The maximum air circulation volume of the air conditioner 19 is 900m 3 / h, the ambient temperature is -45~55℃; the vent 20 is arranged at the top of the front side of the cabin, and the vents 20 are arranged horizontally, which can evenly transport cold and warm air, and have the function of adjustable air volume and wind direction. The use of the desalination machine 18 can effectively reduce the degree of salt fog in the cabin air, thereby slowing down the corrosion effect of the cabin equipment, extending the service life of the equipment, and improving the reliability of the entire cabin.

[0041] In order to further adapt to the application in the high temperature, high humidity and high salt fog island environment, it is necessary to improve the corrosion resistance of the shelter. Therefore, the various structural parts in the shelter can be selected and processed according to the requirements of the following Table 1:
