Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated cabins, and specifically provides a pipe busbar waterproof structure of a prefabricated cabin. Background Art

[0002] The tubular busbar (also called tubular busbar or tubular busbar) in the prefabricated cabin needs to pass through the prefabricated cabin wall of the prefabricated cabin to connect the lines inside and outside the prefabricated cabin, so as to achieve the function of transmitting electrical energy.

[0003] Since the busbar connects the inside and outside of the prefabricated cabin, it is necessary to open a hole in the prefabricated cabin wall or door panel of the prefabricated cabin when installing the busbar. When it rains outside, rainwater from the outside can flow along the busbar. When rainwater from the outside flows to the connection between the busbar and the prefabricated cabin wall, rainwater from the outside can enter the prefabricated cabin from the opening on the prefabricated cabin wall or door panel of the prefabricated cabin, causing water to enter the prefabricated cabin. Therefore, the problem of water easily entering the connection between the busbar and the prefabricated cabin needs to be solved urgently. Utility Model Content

[0004] The utility model provides a pipe busbar waterproof structure of a prefabricated cabin, which is used to solve the problem that water easily enters the connection between the pipe busbar and the prefabricated cabin.

[0005] The technical solution of the utility model is as follows:

[0006] A pipe busbar waterproof structure of a prefabricated cabin comprises a pipe mother cover and a sealing body, wherein the pipe mother cover is sleeved on the pipe busbar, the sealing body is arranged at the connection between the pipe mother cover and the pipe busbar, the sealing body is used to seal the gap between the pipe mother cover and the pipe busbar, one end of the pipe mother cover is connected to a prefabricated cabin wall of the prefabricated cabin, a sealing body is also arranged between the pipe mother cover and the prefabricated cabin wall of the prefabricated cabin, and the sealing body is used to seal the gap between the pipe mother cover and the prefabricated cabin wall of the prefabricated cabin.

[0007] In this scheme, a tube cover is provided on the prefabricated cabin wall of the prefabricated cabin, and the connection between the tube busbar and the prefabricated cabin can be shielded by the tube cover, thereby preventing rainwater from outside from falling directly on the connection between the tube busbar and the prefabricated cabin, thereby achieving a waterproof effect. A sealing body is provided between the tube cover and the tube busbar, and a seal can be formed between the tube cover and the tube busbar through the sealing body to prevent external moisture from flowing into the prefabricated cabin along the tube busbar. A sealing body is provided at the connection between the tube cover and the prefabricated cabin, so that a seal is formed between the tube cover and the prefabricated cabin, preventing external moisture from flowing along the prefabricated cabin wall of the prefabricated cabin to the connection with the tube busbar, thereby preventing external moisture from flowing into the prefabricated cabin.

[0008] In order to solve the problem that the mother tube cover cannot be directly installed after the mother tube bar is installed, the mother tube cover includes at least two unit pieces, and each unit piece is arranged along the circumferential direction to form the mother tube cover.

[0009] In this solution, the busbar cover is composed of multiple unit pieces. Therefore, when installing the busbar cover, each unit piece can be installed separately around the busbar, that is, the installation of the busbar cover can be realized around the already installed busbar, solving the problem that the busbar cover cannot be installed after the busbar is installed.

[0010] Preferably, a sealant is provided between the busbar cover and the prefabricated cabin wall of the prefabricated cabin.

[0011] In this solution, setting the sealant can further improve the sealing performance between the busbar cover and the prefabricated cabin.

[0012] Preferably, the sealing body includes a sealing strip and / or a gasket. The gasket is annular in shape, and the sealing strip is strip-shaped.

[0013] In this solution, the sealing strip or gasket can be selected according to the usage situation. For example, the gasket can be sleeved in advance before installing the busbar, and the sealing is carried out through the gasket. Another example is that after the busbar is installed, the sealing between the busbar cover and the busbar or the prefabricated cabin wall is realized through the sealing strip.

[0014] Preferably, one end of the busbar cover away from the prefabricated cabin is provided with an end face. The end face is provided with a busbar limiting hole. The busbar cover is connected to the prefabricated cabin wall of the busbar through the busbar limiting hole, and the sealing body is arranged at the connection between the busbar limiting hole and the busbar.

[0015] In this solution, one end face of the busbar cover is connected to the prefabricated cabin wall of the busbar. Therefore, the diameter of the busbar cover is larger than that of the busbar. Therefore, there is an annular space between the busbar cover and the busbar. Even if the sealing body between the end panel and the busbar is damaged and water enters the busbar cover, the water that enters will flow to the bottom of the busbar cover under the action of gravity. Obviously, the height of the bottom of the busbar cover is lower than the height of the connection position between the busbar and the prefabricated cabin wall, preventing the entered water from directly entering the prefabricated cabin and enhancing the waterproof effect.

[0016] Preferably, it further includes a rainproof eaves. The rainproof eaves is connected to the prefabricated cabin wall of the prefabricated cabin. The rainproof eaves is arranged on the upper side of the busbar cover, and the rainproof eaves is used to block the rain on the upper side of the busbar cover.

[0017] In this solution, setting the rainproof eaves can block the rain, prevent the rain from directly falling on the busbar cover, reduce the contact time between the busbar cover and water, thereby reducing the probability of water entering the busbar cover and achieving a better waterproof effect.

[0018] To solve the problem that the water on the rainproof eaves directly drops onto the busbar, causing a large amount of water to flow along the busbar to the busbar cover, for this reason, the side of the rainproof eaves away from the prefabricated cabin is provided with an upward flanging. The flanging is used to guide the water flow to both sides of the rainproof eaves, and the busbar cover is located between the two side edges of the rainproof eaves.

[0019] In this solution, the hem on the rainproof eaves can guide the water flow to both sides, and the water flow is discharged from both sides, thus preventing the water flow from directly falling on the pipe busbar.

[0020] Preferably, the prefabricated cabin wall connected to the pipe bus cover is made of stainless steel plate, and the stainless steel plate is provided with a through hole through which the pipe busbar passes.

[0021] In this solution, the prefabricated cabin wall connected to the pipe bus cover is made of stainless steel plate, and the stainless steel plate itself has the property of preventing eddy current, which can avoid the occurrence of eddy current phenomenon when the pipe busbar passes through the prefabricated cabin wall of the prefabricated cabin.

[0022] Preferably, the stainless steel plate is provided with an insulating plate, and the insulating plate is connected to the prefabricated cabin wall of the pipe busbar.

[0023] In this solution, setting the insulating plate can play a role in supporting the pipe busbar, and the insulating plate can also avoid causing eddy current in the pipe busbar while supporting the pipe busbar.

[0024] Preferably, the insulating plate is connected to the stainless steel plate through a sealant, and a sealing body is also provided between the insulating plate and the pipe busbar, and the sealing body is used to form a seal between the insulating plate and the pipe busbar.

[0025] In this solution, forming a seal between the insulating plate and the pipe busbar can further achieve a waterproof effect.

[0026] Advantages of the present utility model:

[0027] The pipe bus cover provided by the present utility model can form seals on the pipe busbar and the prefabricated cabin wall of the prefabricated cabin respectively, which can prevent external moisture from entering the prefabricated cabin along the pipe busbar, and can also prevent external moisture from flowing into the connection position between the pipe busbar and the prefabricated cabin wall of the prefabricated cabin, achieving the purpose of preventing external moisture from entering the prefabricated cabin.

[0036] Combined with the drawings, through the specific implementation manners of the embodiments of the present invention, the technical solutions of the present invention are clearly and completely described.

[0037] Embodiment 1:

[0038] As Figure 1 shown, the first embodiment provides a waterproof structure for the pipe busbar of a prefabricated cabin, which is installed on the prefabricated cabin wall 3 of the prefabricated cabin and is used to prevent external moisture from entering the prefabricated cabin at the connection between the prefabricated cabin and the pipe busbar 4. The waterproof structure includes a pipe bushing cover 1 and a sealing body 2. The pipe bushing cover 1 is sleeved on the pipe busbar 4, and one end of the pipe bushing cover 1 is fixedly connected to the prefabricated cabin wall 3 of the prefabricated cabin. The pipe bushing cover 1 is an overall cylindrical structure, so as to play a role in blocking external moisture circumferentially. A sealing body 2 is arranged at the connection between the pipe bushing cover 1 and the pipe busbar 4 to seal the connection between the pipe bushing cover 1 and the pipe busbar 4 and prevent moisture from entering the pipe bushing cover 1 between the pipe bushing cover 1 and the pipe busbar 4. A sealing body 2 is also arranged between the pipe bushing cover 1 and the prefabricated cabin wall 3 of the prefabricated cabin. Through the sealing body 2, the sealing between the pipe bushing cover 1 and the prefabricated cabin wall 3 can be realized, and external moisture can be prevented from flowing into the pipe bushing cover 1 from the prefabricated cabin wall 3.

[0039] The shape of the pipe bushing cover 1 is a cylindrical structure, which can be a square cylinder or a circular cylinder. It needs to be sleeved on the pipe busbar 4. After the pipe busbar 4 is installed, it is obviously impossible to remove the pipe busbar 4 and then put on the pipe bushing cover 1 again. Therefore, the pipe bushing cover 1 is composed of at least two unit pieces. The pipe bushing cover 1 is divided in the radial direction to form a number of unit pieces arranged in a circle.

[0040] The number of unit pieces can be two, three, four or more. The sizes of the respective unit pieces can be the same, and the sizes of the respective unit pieces can also be different.

[0041] The fewer the number of unit pieces, the higher the installation efficiency. Therefore, the pipe bus cover 1 is preferably composed of two unit pieces, and the two unit pieces have the same size and each form a semi-circular cover body. During installation, the two unit pieces are arranged vertically, and the gap at the connection of the two unit pieces is horizontal to prevent external moisture from entering the pipe bus cover 1 through the gap at the connection of the two unit pieces. A sealing body 2 can also be provided at the connection of the two unit pieces for sealing, or sealant can be injected at the connection of the two unit pieces to achieve sealing through the sealant.

[0042] One end of the pipe bus cover 1 is connected to the prefabricated cabin wall 3 of the prefabricated cabin through fasteners. As Figure 2 shown, a flange 101 is provided at the end of the pipe bus cover 1 connected to the prefabricated cabin wall 3. The setting of the flange 101 facilitates the opening of holes, so that fasteners such as screws can pass through the holes on the flange 101 and be connected to the prefabricated cabin wall 3. When using fasteners such as screws for connection, sealant can be applied to the screws. When the flange 101 is connected to the prefabricated cabin wall 3, one side of the flange 101 abuts against the prefabricated cabin wall 3, and the sealing body 2 between the pipe bus cover 1 and the prefabricated cabin wall 3 is arranged between the flange 101 and the prefabricated cabin wall 3.

[0043] As Figure 3 shown, the pipe bus cover 1 includes an end face 102, a cylindrical part, and a flange 101. The two ends of the cylindrical part are respectively connected to the end face 102 and the flange 101

[0044] Since the pipe bus cover 1 is divided into at least two unit pieces, the flange 101 is also correspondingly divided into multiple parts, and each part is respectively arranged on the unit piece.

[0045] One end of the pipe bus cover 1 is provided with a flange 101, and the other end is provided with an end face 102 extending in the radial direction and towards the axis. The end face 102 is perpendicular to the axis. A pipe bus limiting hole 103 is opened in the middle of the end face 102, and the pipe bus line 4 passes through the pipe bus limiting hole 103. The pipe bus limiting hole 103 can abut against the prefabricated cabin wall 3 of the pipe bus line 4. The sealing body 2 between the pipe bus cover 1 and the pipe bus line 4 is arranged at the connection of the pipe bus limiting hole 103 and the pipe bus line 4.

[0046] The sealing body 2 can be a strip-shaped sealing strip, and the sealing body 2 can also be an annular sealing gasket. When setting the sealing body 2, sealant can also be added to further improve the sealing performance.

[0047] Embodiment 2:

[0048] This Embodiment 2 provides a waterproof structure for the pipe bus in a prefabricated cabin. Different from Embodiment 1, it further includes a rain eaves.

[0049] As Figure 4As shown in the figure, the rainproof eaves are arranged on the prefabricated cabin wall 3 of the prefabricated cabin, and the rainproof eaves are located on the upper side of the pipe bus cover 1. Taking the direction perpendicular to the prefabricated cabin wall 3 as the length direction, the length of the rainproof eaves is greater than the length of the pipe bus cover 1 to ensure that the rainproof eaves can completely block the rainwater on the upper side of the pipe bus cover 1. The width of the rainproof eaves is also greater than the width of the pipe bus cover 1, and the left and right sides of the rainproof eaves can completely block the pipe bus cover 1.

[0050] On the side of the rainproof eaves away from the prefabricated cabin wall 3, there is an upward bend 6. When the rainwater flows to the position of the bend 6, blocked by the bend 6, the rainwater will flow to both sides, which can prevent the rainwater on the rainproof eaves from directly falling on the pipe bus line 4.

[0051] The bend 6 can also increase the strength of the rainproof eaves and prevent the rainproof eaves from deforming.

[0052] The bend 6 can directly bend the rainproof eaves into shape. The rainproof eaves are formed by bending a plate, and the rainproof eaves are fixedly connected to the prefabricated cabin wall 3 of the prefabricated cabin through fasteners. A seal 2 or sealant is also provided between the rainproof eaves and the prefabricated cabin wall 3 of the prefabricated cabin.

[0053] Embodiment Three:

[0054] This Embodiment Three provides a waterproof structure for the pipe bus line of a prefabricated cabin. Different from Embodiment One, in this Embodiment Three, the prefabricated cabin wall 3 on which the pipe bus cover 1 is installed is made of stainless steel plate.

[0055] As Figure 5 shown, through holes are provided on the stainless steel plate, and the diameter of the through holes is greater than the diameter of the pipe bus line 4. The pipe bus line 4 passes through the through holes. The stainless steel plate has the property of preventing eddy currents, which can avoid generating eddy currents when the pipe bus line 4 passes through the prefabricated cabin wall 3.

[0056] An insulating board 7 is arranged on the prefabricated cabin wall 3, such as a plastic board, a foamed board, etc.

[0057] The insulating board 7 is respectively connected to the prefabricated cabin wall 3 and the pipe bus line 4. The insulating board 7 plays a role in supporting the pipe bus line 4 to prevent the pipe bus line 4 from directly contacting the prefabricated cabin wall 3.

[0058] A seal 2 is provided at the connection between the insulating board 7 and the pipe bus line 4, and a sealant is provided at the connection between the insulating board 7 and the prefabricated cabin wall 3 to prevent moisture from entering the prefabricated cabin through the gaps between the insulating board 7, the pipe bus line 4, and the prefabricated cabin wall 3.

[0059] There are two insulating boards 7. The sides of the insulating board 7 are provided with semi-circular notches. The two semi-circular notches are combined to form a circular hole, and the diameter of the combined hole is adapted to the diameter of the pipe bus line 4. The insulating board 7 abuts against the pipe bus line 4 from the circumferential direction, playing a role in supporting the pipe bus line 4 and restricting the position of the pipe bus line 4.

[0060] It should be noted that the third embodiment can also be applied to the second embodiment.
