Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated cabin technology, and in particular to a prefabricated cabin sealing structure. Background Technology
[0002] Based on the "standard delivery" concept, outdoor intelligent substations mostly adopt prefabricated module technology for integrated engineering production. They can be directly adapted and installed on-site, resulting in more reliable quality and shorter construction period, meeting the needs of rapid power grid construction.
[0003] The existing prefabricated cabin has a sealed overall structure. The quality of the seal depends mainly on the door panel. Due to maintenance and other needs, movable door panels must be provided. Generally, the door panel is square, which is suitable for sealing with a square-shaped sealing strip. The sealing structure is simple and easy to implement. However, based on the square structure, sewage can easily accumulate on the top of the sealing strip, causing damage to the sealing strip and affecting the sealing performance. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a prefabricated cabin sealing structure that addresses the above-mentioned technical deficiencies. This structure solves the problem that sewage can easily accumulate above the existing sealing strip, causing damage to the sealing strip and affecting the sealing performance.
[0005] The technical solution adopted by this utility model is: providing a prefabricated cabin sealing structure, including a door frame plate located on one side of the prefabricated cabin; the door frame plate has a first window, the upper part of which is arc-shaped; and further includes:
[0006] A sealing ring, adapted to the shape of the first window, is disposed at the front end of the door frame plate and located around the first window;
[0007] The cover has a second window in the middle that is adapted to the shape of the first window. The cover is disposed at the front end of the door frame plate and covers the sealing ring. The front part of the sealing ring abuts against the inner wall of the second window.
[0008] A door panel is rotatably mounted on the cover or the door frame plate. The door panel is used to cover the second window. After the door panel covers the second window, the sealing ring abuts against the door panel.
[0009] To further optimize this technical solution, the front end of the door frame panel has an installation plate, the installation plate is disposed around the first window, and the rear of the sealing ring is engaged with the installation plate.
[0010] To further optimize this technical solution, the front section of the sealing ring is trapezoidal, with the two inclined surfaces of the trapezoid being the outer inclined surface and the inner inclined surface, respectively. The outer inclined surface abuts against the inner wall of the second window. The rear part of the door panel has a fixing ring adapted to the shape of the second window. The fixing ring is located inside the second window and is used to abut against the inner inclined surface.
[0011] To further optimize this technical solution, after the door panel covers the second window, the fixing ring and the side wall of the second window form an annular groove with a triangular cross section. The front part of the sealing ring is located in the annular groove, and the front end of the sealing ring is spaced from the front end of the annular groove. The front end of the sealing ring has a plurality of evenly distributed guide columns along the annular ring, and the guide columns are located within the interval.
[0012] To further optimize this technical solution, the lower part of the cover has a vertically arranged drainage hole, the upper end of which is connected to the annular groove, and the lower end of which is connected to the outside of the prefabricated cabin.
[0013] To further optimize this technical solution, the cover is welded to the front end of the door frame panel.
[0014] To further optimize this technical solution, the front end of the cover abuts against the door panel, and the upper part of the front end of the cover has an arc-shaped drainage groove, which is located above the second window.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. The sealing ring is adapted to the shape of the first window, and the upper part is arc-shaped and arched. After water enters the upper part of the sealing ring, it can flow smoothly down along both sides of the arc, reducing water accumulation and soaking in the upper part of the sealing ring, which helps to extend the sealing service life of the sealing ring.
[0017] 2. The shape of the first window is adapted to the sealing ring, which can keep the area of the first window as large as possible, making it convenient for the maintenance of equipment and components inside the prefabricated cabin. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0029] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0032] like Figure 1-9As shown, a prefabricated cabin sealing structure includes a door frame plate 1 located on one side of the prefabricated cabin; the door frame plate 1 has a first window 101, the upper part of the first window 101 is arc-shaped; it also includes: a sealing ring 2, which is adapted to the shape of the first window 101, is disposed at the front end of the door frame plate 1, and is located around the first window 101; a cover 3, which has a second window 301 in the middle that is adapted to the shape of the first window 101, the cover 3 is disposed at the front end of the door frame plate 1, and covers the sealing ring 2, the front part of the sealing ring 2 abuts against the inner wall of the second window 301; a door plate 4, which is rotatably disposed on the cover 3 or the door frame plate 1, the door plate 4 is used to cover the second window 301, and after the door plate 4 covers the second window 301, the sealing ring 2 abuts against the door plate 4.
[0033] In use, the upper part of the first window 101 can be semi-circular (the semi-circular part is the upper arc shape), and the lower part is roughly square. The upper part of the sealing ring 2 is also arc-shaped, which matches the shape of the first window 101. That is, the upper part of the sealing ring 2 is semi-circular, the lower part is square, and it surrounds the outer perimeter of the first window 101. The cover 3 is a box-shaped structure, which covers the front end of the door frame plate 1 and abuts against the sealing ring 2 to achieve a seal. The door plate 4 is rotatably set, which can be rotatably set on one side of the cover 3 or rotatably set on the door frame plate 1. After rotation, it can abut against the sealing ring 2 to seal or open.
[0034] The upper part of the sealing ring 2 is a semi-circular arc, which can maintain a large opening area (the sealing ring 2 surrounds the outside of the first window 101, and the opening area inside the sealing ring 2 affects the opening area of the first window 101). At the same time, it has a good effect of guiding water flow to both sides and downwards, reducing water accumulation at the top. After flowing downwards, the water can be discharged through gaps, etc. Even if it is not discharged, when the water accumulation is small, due to gravity, the water level is relatively thin and located at a low position, and may not contact the lower sealing ring 2.
[0035] The door panel 4 and the cover 3, or the door panel 4 and the door frame panel 1, are rotatably connected for easy opening and closing. This is existing technology and can be achieved using existing structures such as hinges, pivots, and swivels. This is not the area to be improved in this sealing structure. The rotatable structure is not shown in the illustration. The rotatable connection structure and its position can be set according to actual needs. For example, a rotatable connection can be set on the left side to achieve left and right rotation, or a rotatable connection can be set on the upper part to achieve up and down rotation. It can also be understood that a shield can be set on the upper part of the door frame panel 1 or the upper part of the cover 3 so that the upper gap where the door panel 4 and the cover 3 meet faces forward rather than upward. This is existing technology.
[0036] In the diagram, the sealing ring 2 and the cover 3 are convex relative to the door frame plate 1. It should be understood that the first window 101 structure of the door frame plate 1 is continuous from front to back. The surrounding structure of the first window 101 can be recessed to the rear of the door frame plate 1, i.e., inside the prefabricated cabin, so that the sealing ring 2 and the cover 3 do not convex. The cover 3 can be flush with the front end of the door frame plate 1. At this time, due to structural production limitations, the mounting plate 102 can be a rear-mounted component of the door frame plate 1.
[0037] Shape matching refers to shapes that are the same or similar.
[0038] Furthermore, the front end of the door frame panel 1 has a mounting plate 102, which is located around the first window 101, and the rear of the sealing ring 2 is secured to the mounting plate 102.
[0039] In use, the cross section of the mounting plate 102 can be "T" shaped, and the rear part of the sealing ring 2 can have a slot that fits the "T" shape, which is then fitted onto the mounting plate 102 to achieve a sealed installation.
[0040] Furthermore, the front section of the sealing ring 2 is trapezoidal, with the two inclined surfaces being the outer and inner inclined surfaces, respectively. The outer inclined surface abuts against the inner wall of the second window 301. The rear part of the door panel 4 has a fixing ring 401 adapted to the shape of the second window 301. The fixing ring 401 is located inside the second window 301 and is used to abut against the inner inclined surface. After the door panel 4 covers the second window 301, the fixing ring 401 and the side wall of the second window 301 form an annular groove 402 with a triangular cross section. The front part of the sealing ring 2 is located in the annular groove 402, and there is a gap between the front end of the sealing ring 2 and the front end of the annular groove 402. The front end of the sealing ring 2 has several evenly distributed guide columns 5 along the annulus, and the guide columns 5 are located within the gaps.
[0041] When in use, the sealing ring 2 is annular in shape, with an inner ring surface and an outer ring surface. The front cross-section is trapezoidal, meaning the outer ring surface is the outer inclined surface and the inner ring surface is the inner inclined surface, which can better seal with the door panel 4 and the cover 3.
[0042] The inner annular wall of the second window 301 is inclined, and the inner side of the fixing ring 401 at the rear of the door panel 4 that contacts the sealing ring 2 is also inclined. After the door panel 4 abuts against the cover 3, it covers the front of the second window 301. The fixing ring 401 is located inside the second window 301. The fixing ring 401 and the second window 301 form a triangular annular groove 402. The cross section of the annular groove 402 is triangular, and the whole is annular and fits the sealing ring 2. All the trapezoidal parts of the sealing ring 2 are located in the annular groove 402 to achieve sealing.
[0043] The several guide columns 5 at the front of the sealing ring 2 serve to guide water flow, accelerating the flow of accumulated water. When the water accumulation is small, the guide columns 5 can improve the flowability. The guide columns 5 are distributed in multiple rings with small gaps between adjacent columns, ranging from 0.5 mm to 1.5 mm, achieving a good drainage effect. When rainwater enters the annular groove 402, the guide columns 5 can more quickly guide the upper water downwards. For clarity, the distribution of the guide columns 5 in the illustration is relatively far apart and does not represent the actual density.
[0044] Furthermore, the lower part of the cover 3 has a vertically arranged drainage hole 302, the upper end of the drainage hole 302 is connected to the annular groove 402, and the lower end of the drainage hole 302 is connected to the outside of the prefabricated cabin.
[0045] During use, accumulated water flows downwards within the annular groove 402 and can drain out through gaps. A drain hole 302 is provided at the lower part of the cover 3 to accelerate drainage. The drain hole 302 is located at the lower part of the annular groove 402; rainwater collected at the lower part of the annular groove 402 can drain out through the drain hole 302. The drain hole 302 connects to the annular groove 402 at the gap between the front end of the sealing ring 2 and the front end of the annular groove 402, and is located below the guide column 5.
[0046] Furthermore, the cover 3 is welded to the front end of the door frame panel 1.
[0047] During use and installation, the sealing ring 2 is first fitted onto the front mounting plate 102 of the door frame plate 1, and then the cover 3 is installed. The cover 3 is fixedly connected to the front end of the door frame plate 1. Existing sealing measures can be used to seal the connection between the cover 3 and the door frame plate 1, or it can be directly welded along the ring to achieve a sealed fixation.
[0048] Furthermore, the front end of the cover 3 abuts against the door panel 4, and the upper part of the front end of the cover 3 has an arc-shaped drainage groove 303, which is located above the second window 301.
[0049] When in use, the drainage groove 303 at the front end of the cover 3 is arc-shaped and arched upwards, located above the second window 301. When rainwater enters from the joint between the door panel 4 and the upper end of the cover 3, it first flows downwards to both sides through the drainage groove 303, maintaining the contact between the rainwater and the upper part of the sealing ring 2.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
