Description

Technical Field

[0001] This utility model belongs to the field of automated measurement technology of dam appearance, and more specifically, it relates to a rainproof device and rainproof structure suitable for the area between the roof of the station and the observation pier. Background Technology

[0002] In the design and construction of existing automated monitoring stations on the exterior of dams, in order to prevent the observation piers exposed from the roof from affecting the degree of freedom of the observation piers due to thermal expansion and contraction, and thus affecting the data accuracy when observing from the observation piers, a window ring with a width of about 50mm and a shape of ring or square is generally reserved or chiseled between the two. The window ring is then filled and sealed with flexible materials (foam, asphalt, etc.) to prevent water from entering.

[0003] However, over time, flexible materials are prone to hardening and caking, which leads to two drawbacks: First, when the temperature of the roof of the observation station changes, the hardened and caking flexible material will constrain the observation pier, affecting its degree of freedom and thus the accuracy of the observation. Second, there are small gaps or unevenness at the connection between the two, which are easily eroded and seeped by rainwater, causing indoor water seepage and interfering with the normal operation of the observation equipment in the observation station.

[0004] This problem is particularly prominent in rainy areas or environments with variable climates, becoming a significant factor affecting the long-term stable operation of observation stations. Therefore, developing a specialized device that can effectively fill the gaps in the observation rings while preventing rainwater leakage has become a primary task. Utility Model Content

[0026] This utility model embodiment uses the "Construction of Automated System for Surface Deformation Monitoring in the Xiluodu Hydropower Station Hub Area" project as its research and development base and application scenario. The project's 27 automated observation stations are distributed in the high-altitude, rainy areas on both sides of the hydropower station dam area, facing harsh environments with significant temperature variations on the station roofs and high requirements for observation accuracy. The research and development concept of this utility model embodiment is to install a special rain cover in the gap area between the existing station roof and the observation pier. This rain cover not only creates a gap of more than 50mm between the station roof and the observation pier to eliminate the constraint of thermal expansion and contraction of the roof on the observation pier, but also effectively prevents rainwater from seeping into the room through the gap in the gap. The rainproof device of this utility model embodiment uses corrosion-resistant stainless steel to ensure the durability and stability of the rain cover in various harsh environments. Through multiple tests and optimizations, this utility model embodiment finally determined a rainproof device with a simple structure, significant effect, and easy installation, providing a new technical solution for the protection of the observation piers on the station roof.

[0027] Please see Figures 1-5 The present invention will now describe a rainproof device and rainproof structure applicable between the roof of a station and the observation pier provided by an embodiment of the present invention.

[0028] In one embodiment of this utility model, a rainproof device applicable between the roof of a station building and an observation pier includes a metal base 1 and a metal rain cover 2. The metal base 1 includes a horizontal base plate 101 and a vertical sleeve 102 connected to the horizontal base plate 101. The metal base 1 has a first mounting hole 103 at its center. The metal rain cover 2 has a second mounting hole 201 at its center. The metal rain cover 2 covers the metal base 1, and the lower side of the metal rain cover 2 abuts against the horizontal base plate 101. The first mounting hole 103 and the second mounting hole 201 are used to pass through the observation pier 3. The horizontal base plate 101 is used to connect the edge of the window ring 5 of the roof of the station building 4.

[0029] The rainproof device of this utility model embodiment consists of two parts: a metal base 1 and a metal rain cover 2. The dimensions of the first mounting hole 103 and the second mounting hole 201 are approximately the same as the size of the observation pier 3, so that the rainproof device can be nested around the outer periphery of the observation pier 3 after installation. After nesting, the window ring 5 between the station roof 4 and the observation pier 3 can still offset the expansion and contraction deformation of the station roof 4 caused by temperature changes, thereby ensuring the freedom of movement and observation accuracy of the observation pier 3. On the other hand, the two-part combined design of the rainproof device is easy to install. The rainproof device can be nested from the top of the observation pier 3 downwards without disassembling or moving the observation pier 3, which is suitable for on-site construction conditions. In addition, this two-part nested structure of the rainproof device can form a double protective barrier. The metal base 1 is installed close to the edge of the window ring 5 of the station roof 4, which can block most of the rainwater from directly seeping in. The metal rain cover 2 covers the metal base 1, and its edge is tightly fitted to the metal base 1, further intercepting rainwater that may seep in from the gaps in the metal base 1. The rainproof device of this utility model adopts a "double coverage + nested sealing" design, which makes its waterproof reliability higher, especially in harsh environments such as heavy rain and strong winds, it can significantly reduce the risk of leakage. Furthermore, the metal base 1 is connected to the roof 4 of the station building during installation, providing a fixed foundation for the entire rainproof device, while the metal rain cover 2 is responsible for the main rainproof coverage. The combination of the two parts can disperse the impact of external forces (such as wind and vibration) on the device, avoid the loosening or deformation of a single structure due to long-term stress, and ensure that the waterproof performance does not decrease during long-term use.

[0030] The two-part combination design of the rainproof device in this embodiment of the present invention is the optimal design structure that takes into account the ease of installation, waterproof effect and structural stability.

[0031] A rainproof device for use between the roof of a station building and the observation pier according to an embodiment of the present invention is installed in the area of ​​the window ring 5 between the roof of the station building 4 and the observation pier 3. The metal base 1 is connected to the roof of the station building 4, and the metal rain cover 2 is placed on the metal base 1. After the rainproof device of this embodiment of the present invention is installed, it can not only eliminate the constraint of the thermal expansion and contraction of the roof of the station building 4 on the observation pier 3, but also effectively prevent rainwater from seeping into the room through the gap at the window ring 5.

[0032] The main body of the rainproof device in this embodiment is made of stainless steel, that is, the metal base 1 and the metal rain cover 2 are made of stainless steel sheet. The choice of stainless steel material ensures the corrosion resistance and long-term stability of the device, so as to ensure that it can maintain its structural integrity and functionality even when exposed to the outdoor environment for a long time. Preferably, corrosion-resistant and high-strength 304# stainless steel is selected, and the thickness of the stainless steel sheet is generally between 1.0mm and 1.5mm.

[0033] Based on the specific shape (circular or square) of the observation pier 3, the rainproof device of this utility model embodiment is divided into circular (e.g., Figure 1 , Figure 3 (as shown) and square (as shown) Figure 2 , Figure 4 As shown, there are two designs to accommodate different shapes of the observation pier 3. The first mounting hole 103 and the second mounting hole 201 are designed to be circular or square respectively. The rainproof device can perfectly fit around the exposed observation pier 3 and the connection with the roof 4 of the station building, forming an effective protective barrier.

[0034] Preferably, the inner wall of the second mounting hole 201 abuts against the outer wall of the vertical sleeve 102, that is, the metal rain cover 2 is tightly fitted with the metal base 1. In this way, the metal rain cover 2 can be seamlessly covered on the metal base 1, improving the leak-proof effect of the rainproof device.

[0035] In one embodiment, when the rainproof device is designed to be circular, the horizontal base plate 101 is annular, the vertical sleeve 102 is circular, and the metal rain cover 2 is annular.

[0036] In another embodiment, when the rainproof device is designed to be square, the horizontal base plate 101 is square, the vertical sleeve 102 is square, and the metal rain cover 2 is square.

[0037] This utility model embodiment also provides a rainproof structure suitable for the space between the station roof and the observation pier, including the aforementioned rainproof device, the station roof 4, and the observation pier 3, as shown below. Figure 2 , Figure 4As shown, the observation pier 3 passes through the roof 4 of the station building, and a window ring 5 is provided between the observation pier 3 and the roof 4 of the station building; the horizontal base plate 101 of the metal base 1 is fixedly connected to the edge of the window ring 5, and the observation pier 3 passes through the first mounting hole 103 of the metal base 1 and the second mounting hole 201 of the metal rain cover 2. The inner wall of the second mounting hole 201 abuts against the outer wall of the observation pier 3.

[0038] Depending on the shape of the observation pier 3, the window ring 5 is either ring-shaped or square, and the width of the window ring 5 is more than 50mm, so as to eliminate the constraint of thermal expansion and contraction of the roof 4 of the station on the observation pier 3.

[0039] The rainproof structure of this utility model embodiment can be installed according to the following process, as follows: Figure 5 As shown: 1) Reserve or chisel out a 5-inch window ring. Along the area around the connection between the roof of the station building 4 and the observation pier 3, a window ring 5 with a width of at least 50mm should be reserved or chiseled out in advance to ensure that the observation pier 3 has sufficient freedom under thermal expansion and contraction.

[0040] 2) Customization and installation of stainless steel rainproof devices Based on the specific shape (circular or square) and size of the observation pier 3, a corresponding stainless steel rainproof device is customized. During the customization process, the size of the opening ring 5 at the bottom of the observation pier 3 is first measured to ensure that the rain cover specifications can be accurately wedged into the observation pier 3 and the roof of the station building 4. During installation, after fixing the metal base 1 at the bottom of the rain cover, the stainless steel metal rain cover 2 is slowly and precisely nested into the metal base 1 from above the observation pier 3, so that it can just cover the opening ring 5 of the roof of the station building 4.

[0041] 3) Waterproofing treatment around the edges of the rain cover To ensure the sealing and waterproof performance of the device, high-quality waterproof materials and strong adhesives were used to evenly seal and bond the edges of the stainless steel rain cover, observation pier 3, and the roof of the station building 4. The selection of waterproof materials and strong adhesives must fully consider their durability and bonding strength to ensure that they can maintain good waterproof performance even after long-term exposure to outdoor environments.

[0042] 4) Inspection and Testing Acceptance After installation, the device underwent rigorous inspection and testing. Visual inspection, dimensional measurement, and performance testing were used to ensure that the installation location, dimensions, shape, and waterproofing performance met design requirements. After more than a year of testing and observation results comparison, it was confirmed that the rain cover device effectively ensured the freedom of movement of the observation pier 3 exposed on the roof and significantly improved water seepage at the connection point with the roof.

[0043] The rainproof structure of this embodiment requires precise positioning and installation of the stainless steel rainproof device in the open area 5 around the station roof 4 and observation pier 3. Then, waterproof material and strong adhesive are used to firmly bond the edges around the rain cover to achieve a seal and waterproofing. Simultaneously, a gap of at least 50mm must be maintained between the rain cover and the station roof 4 to prevent thermal expansion and contraction of the observation pier 3 due to temperature changes on the station roof 4, which could affect observation accuracy.

[0044] The installation process of the rainproof structure in this embodiment is simple and efficient: First, select a suitable type of rainproof device according to the shape of the observation pier 3; second, accurately position the connection point around the window ring 5 between the station roof 4 and the observation pier 3; then, use the pre-processed stainless steel rainproof device to cover the window ring 5 around the perimeter of the observation pier 3, ensuring that the edge of the rain cover fits tightly with the edge of the window ring 5; finally, use waterproof material and strong adhesive to evenly seal the edge of the rain cover to ensure waterproof effect. The entire installation process requires no complicated tools, is easy to operate, and greatly shortens the construction time.

[0045] The rainproof structure of this embodiment effectively prevents rainwater from seeping into the interior through the tiny gap between the station roof 4 and the observation pier 3, ensuring the dryness and safety of the observation pier 3 and its internal equipment. Simultaneously, the gap design of more than 50mm between them fully considers the thermal expansion and contraction characteristics of the station roof 4, avoiding any constraints on the observation pier 3 and ensuring its freedom of movement and observation accuracy. The use of stainless steel not only gives the device excellent corrosion resistance but also ensures its long-term stable operation under various harsh weather conditions at the Xiluodu Hydropower Station on the Jinsha River. It provides solid and reliable protection for the observation pier 3 on the station roof 4, providing strong support for the continuity and accuracy of scientific observation and data collection.

[0046] The rainproof structure of this utility model is simple and beautiful, which simplifies the installation process and reduces material waste and labor costs during installation. This allows the device to be installed quickly and accurately on the roofs of various types of stations, demonstrating high adaptability and flexibility.

[0047] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
