Description
Technical Field
[0001] The utility model relates to the technical field of prefabricated cabins, and specifically provides a quickly assembled prefabricated cabin. Background Art
[0002] Prefabricated cabins are used to install transformers and other power transformation equipment. When transformers and other equipment are in operation, they will generate a lot of noise, causing noise pollution to the environment. Therefore, the side walls of prefabricated cabins are usually equipped with noise reduction structures such as sound-absorbing layers. At the same time, prefabricated cabins also need to be equipped with fire-proof structures to prevent the fire from spreading outside the prefabricated cabin when a fire occurs on the inner wall of the prefabricated cabin. Therefore, the inner wall of the prefabricated cabin is usually equipped with a noise-reducing and fire-proof protective structure.
[0003] In the prior art, noise reduction is mainly achieved through sound-absorbing cotton. However, the sound-absorbing cotton is very soft, and the sound-absorbing cotton needs to be fixed to the corresponding metal lining, and then the metal lining is fixed to the inner side wall of the prefabricated cabin to achieve the installation of the sound-absorbing cotton. When fixing the sound-absorbing cotton to the metal lining, two hands are needed to unfold the sound-absorbing cotton little by little to make the unfolded part of the sound-absorbing cotton flat. Then the unfolded part of the sound-absorbing cotton is laid and fixed on the metal lining, and the laying efficiency of the sound-absorbing cotton is very low. Therefore, because the laying efficiency of the sound-absorbing cotton is very low, the assembly efficiency of the prefabricated cabin is low, which needs to be solved urgently. Utility Model Content
[0004] The utility model provides a quickly assembled prefabricated cabin, which is used to solve the problem of low assembly efficiency of the prefabricated cabin.
[0005] The technical solution of the utility model is as follows:
[0006] A quick-assembled prefabricated cabin comprises a sound-absorbing keel bracket and a fireproof layer, wherein the fireproof layer is a rigid plate-like structure, the fireproof layer and the sound-absorbing keel bracket are fixed to the side wall of the prefabricated cabin, and the sound-absorbing keel bracket is arranged between the fireproof layer and the side wall of the prefabricated cabin.
[0007] In this solution, a sound-absorbing keel bracket is used to achieve the effect of sound absorption and noise reduction. The sound-absorbing keel bracket is a rigid structure. The sound-absorbing keel can be quickly assembled to form a sound-absorbing keel bracket by welding and fastener connection, which can improve the assembly efficiency. After the sound-absorbing keel bracket is assembled, the fireproof layer and the sound-absorbing keel can be directly fixed to the side wall of the prefabricated cabin by fasteners. Since the fireproof layer is a rigid plate structure, compared with the flexible sound-absorbing cotton, the fireproof layer with a rigid plate structure can be pressed on the sound-absorbing keel bracket by one hand, and the shape of the fireproof layer will not change, which can improve the installation efficiency and solve the problem of low equipment efficiency of the prefabricated cabin caused by low installation efficiency of the fireproof layer.
[0008] To solve the problem that the contact between the sound-absorbing keel bracket and the fireproof layer is uneven, resulting in unstable installation of the fireproof layer, a flexible buffer layer with a deformable thickness is provided between the sound-absorbing keel bracket and the fireproof layer.
[0009] In this solution, a flexible buffer layer with a deformable thickness is provided to solve the problem of unevenness between the fireproof layer and the sound-absorbing keel bracket. When the distances at various positions between the fireproof layer and the sound-absorbing keel bracket are unequal, the pressures received by the flexible buffer layer at the corresponding positions are different, and the thickness of the flexible buffer layer will change adaptively. In the case of the adaptive change in the thickness of the flexible buffer layer, support can be provided for each position of the fireproof layer, avoiding the fireproof layer from being loose due to the hollowing out of the inner side of the fireproof layer.
[0010] Preferably, the flexible buffer layer is felt.
[0011] In this solution, felt is used as the flexible buffer layer. The cost of felt is low, which is convenient for cost control.
[0012] To solve the problem that it is inconvenient to transfer and install the fireproof layer due to its too large size, therefore, the fireproof layer includes at least two fireproof boards, and each fireproof board is respectively connected to the sound-absorbing keel bracket.
[0013] In this solution, the fireproof layer is composed of fireproof boards. According to the area of the fireproof layer, it can be composed of different numbers of fireproof boards. The size of a single fireproof board is smaller than that of the entire fireproof layer, which is more convenient for the transfer and installation of the fireproof boards and reduces the installation difficulty.
[0014] Preferably, the fireproof board is a magnesium oxysulfate board.
[0015] In this solution, using magnesium oxysulfate boards can reduce the weight of the fireproof layer and facilitate the installation of the fireproof layer.
[0016] To solve the problem of low installation efficiency when the fireproof board and the sound-absorbing keel bracket are installed separately, therefore, the sound-absorbing keel bracket is provided with through holes, and fixing holes are provided at the corresponding positions of the fireproof layer. Fasteners are arranged in the fixing holes, and the fasteners pass through the through holes and are connected to the side wall of the prefabricated cabin.
[0017] In this solution, it is stipulated that the fasteners of the fireproof board are also used to fix the sound-absorbing keel bracket. Therefore, when installing the sound-absorbing keel bracket, the sound-absorbing keel bracket and the fireproof board can be overlapped first, and then the sound-absorbing keel bracket and the fireproof board can be installed on the side wall of the prefabricated cabin at the same time. It is not necessary to install the sound-absorbing keel bracket and the fireproof board separately, improving the installation efficiency.
[0018] The beneficial effects of the present utility model:
[0019] The utility model adopts a sound-absorbing keel bracket to eliminate noise. The sound-absorbing keel bracket can be assembled by splicing sound-absorbing keels. When fixing, only the sound-absorbing keel bracket needs to be fixed to the side wall of the prefabricated cabin through fasteners. Since the sound-absorbing keel bracket is a frame, it will not deform during the fixing process, and there is no need to adjust the shape during fixing, which can improve the installation efficiency. Moreover, the fireproof layer is a rigid plate-like structure, and it can also be fixed by pressing with one hand during installation, so as to achieve the purpose of improving the installation efficiency.

[0020] In order to more clearly illustrate the technical solution of the utility model, the drawings required for describing the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] Combined with the drawings, through the specific embodiments of the utility model, the technical solution of the utility model will be clearly and completely described.
[0025] Embodiment 1:
[0026] As Figure 1 shown, Embodiment 1 provides a prefabricated cabin with rapid assembly. The prefabricated cabin includes a sound-absorbing keel bracket 2 for sound insulation and noise reduction. The sound-absorbing keel bracket 2 is fixed to the inner side of the side wall 1 of the prefabricated cabin. The sound-absorbing keel bracket 2 is a frame structure composed of sound-absorbing keels.
[0027] The sound-absorbing keel bracket 2 can be a rectangular frame or a frame structure of other polygons. Preferably, a rectangular frame structure is adopted, and the rectangular frame structure is more convenient for combined use. For example, when the area of a side wall 1 of the prefabricated cabin is large, multiple sound-absorbing keel brackets 2 can be used in combination. Multiple sound-absorbing keel brackets 2 are used to cover the entire side wall 1, so that the entire side wall 1 has the effect of sound absorption and noise reduction everywhere.
[0028] The sound-absorbing keels can be connected to each other by welding, connecting with fasteners 4, etc., so as to form a sound-absorbing keel bracket 2 with a frame structure.
[0029] The sound-absorbing keel bracket 2 is fixed to the side wall 1 of the prefabricated cabin by fasteners 4. The fasteners 4 can be bolts, rivets, etc.
[0030] The sound-absorbing keel bracket 2 can be provided with through holes, and fasteners 4 such as bolts pass through the through holes to connect with the side wall 1, thereby fixing the sound-absorbing keel bracket 2 to the side wall 1 of the prefabricated cabin.
[0031] Alternatively, the sound-absorbing keel bracket 2 can be provided with lugs, through holes are provided on the lugs, and fasteners 4 such as bolts pass through the through holes on the lugs to connect with the side wall 1, which can also achieve the effect of fixing the sound-absorbing keel bracket 2 to the side wall 1.
[0032] A fireproof layer 5 is also provided in the prefabricated cabin. The fireproof layer 5 is also fixed to the side wall 1 of the prefabricated cabin. Among them, the fireproof layer 5 is located outside the sound-absorbing keel bracket 2. Or rather, the sound-absorbing keel bracket 2 is located between the fireproof layer 5 and the side wall 1 of the prefabricated cabin.
[0033] The fireproof layer 5 is located outside the sound-absorbing keel bracket 2. Therefore, the fireproof layer 5 can be connected to the sound-absorbing keel bracket 2 or directly connected to the side wall 1 of the prefabricated cabin.
[0034] When the fireproof layer 5 is connected to the sound-absorbing keel bracket 2, different connection structures need to be set according to different connection methods.
[0035] When the fireproof layer 5 is connected to the sound-absorbing keel bracket 2 by bolts, threaded holes need to be provided on the sound-absorbing keel bracket 2, or nuts are welded on the sound-absorbing keel bracket 2, and the bolts pass through the fireproof layer 5 to connect with the nuts, which can also achieve the purpose of fixing the fireproof layer 5 to the sound-absorbing keel bracket 2.
[0036] The sound-absorbing keel bracket 2 is a frame structure with low dimensional accuracy. Therefore, the surface of the sound-absorbing keel bracket 2 connected to the fireproof layer 5 may be uneven. If the sound-absorbing keel bracket 2 is uneven, the supporting effect on the fireproof layer 5 will be unstable. For example, one corner of the fireproof layer 5 is connected to the sound-absorbing keel bracket 2 or the side wall 1 of the prefabricated cabin by bolts, and there is a depression at the corresponding position of the sound-absorbing keel bracket 2. At this time, there is a gap between the fireproof layer 5 and the sound-absorbing keel bracket 2, and the side of the fireproof layer 5 close to the sound-absorbing keel bracket 2 at this position is not supported. When the prefabricated cabin is transported or other structures are assembled, the side wall 1 of the prefabricated cabin may vibrate. The vibration of the side wall 1 will cause the sound-absorbing keel bracket 2 and the fireproof layer 5 to vibrate, and the vibration of the fireproof layer 5 will change the distance between the fireproof layer 5 and the sound-absorbing keel bracket 2. When the distance between the fireproof layer 5 and the sound-absorbing keel bracket 2 changes, the bolts fixing the fireproof layer 5 will become loose, resulting in unstable fixation of the fireproof layer 5. The supporting effect on the fireproof layer 5 is unstable, and connection structures such as bolts cannot achieve the effect of firmly fixing the fireproof layer 5. Therefore, a flexible buffer pad is provided between the sound-absorbing keel bracket 2 and the fireproof layer 5. After the fireproof layer 5 is fixed by the fasteners 4, the fastening process of the fasteners 4 will apply pressure to the flexible buffer pad, and the flexible buffer pad will be compressed. Even if the dimensional accuracy of the sound-absorbing keel bracket 2 is low and there are uneven positions on the sound-absorbing keel bracket 2, the compression amounts of the flexible buffer pad at the uneven positions will be different. Even if the compression amounts received by the flexible buffer pad are different, the flexible buffer pad is still in a compressed state. Therefore, when the side wall 1 of the prefabricated cabin vibrates, the flexible buffer pad will deform adaptively and always apply a supporting force to the fireproof layer 5 during the deformation process. Since the flexible buffer layer 3 can always apply a supporting force to the fireproof layer 5, the fasteners 4 used to fasten the fireproof layer 5 are always in a stressed state, and the loosening of the fasteners 4 can be avoided.
[0037] The fireproof layer 5 can be a rigid plate structure such as a magnesium oxysulfate board or a calcium carbonate board. Using a rigid plate structure is more convenient for installation and fixation, which can improve the installation efficiency.
[0038] The flexible buffer pad can be made of felt, sponge board, rubber board, and polyurethane foam board with good compressibility, etc.
[0039] When installing the fireproof layer 5, if the area of the fireproof layer 5 is too large, it will be inconvenient to carry and move. Therefore, the fireproof layer 5 can include multiple fireproof boards, and the multiple fireproof boards are respectively connected to the side wall 1 of the prefabricated cabin or to the sound-absorbing keel bracket 2. The multiple fireproof boards are laid flat on the side wall 1 of the prefabricated cabin to form the fireproof layer 5. Each fireproof board can be arranged in a rectangular array or a linear array to form a complete fireproof layer 5.
[0040] The number of fireproof boards can be two, three, four or more. The shape of the fireproof board can be structures such as a rectangular board, a hexagonal board or a triangular board, etc. Preferably, a rectangular board is adopted, which is convenient for processing, storage and handling.
