Description

Technical Field

[0001] This invention relates to the technical field of flood-proof doors and windows, and more particularly to an emergency-type flood-proof door and window. Background Technology

[0002] A power station consists of a hydraulic system, a mechanical system, and an electrical energy generation device. It is a water conservancy project that realizes the conversion of water energy into electrical energy. The sustainability of electrical energy production requires that the utilization of water energy in a hydropower station be uninterrupted.

[0003] Some hydropower stations have their powerhouses located underground, resulting in numerous access tunnels or busbar tunnels. This poses a significant risk of flooding in the powerhouses during floods. Therefore, it is necessary to install flood control facilities at the access roads and busbar tunnels of each power station. These facilities are crucial to prevent flooding in extreme situations such as mudslides caused by localized heavy rainfall, resulting in river blockages and abnormally high water levels. Improving flood control and disaster prevention capabilities under extreme circumstances is urgent and essential.

[0004] Existing flood control facilities typically consist of floodgates installed on access tunnels or busbar tunnels to cope with floods or rising water levels. However, these facilities have certain drawbacks in actual use. Due to the large size of the floodgates, workers entering the access tunnels or busbar tunnels must wait for the large floodgates to open, which is very inconvenient. Furthermore, during the rainy season, in the event of sudden floods or rising water levels, the floodgates cannot be closed in time, leading to water entering the underground powerhouse and damaging the power station equipment. Additionally, the underground powerhouse of hydroelectric power stations often has windows installed at lower locations for ventilation and heat dissipation. These lower-positioned windows are at higher risk of being impacted by floods and mudslides. Floodproof windows are usually installed on the outside of these windows to reduce the risk of damage caused by floods and geological disasters. However, existing floodproof windows use only tempered glass or similar materials for protection. Once a floodproof window breaks, floods or mudslides can easily enter the powerhouse through the window, causing equipment damage. Summary of the Invention

Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1 Reference Figure 1 This is the first embodiment of the present invention, which provides an emergency flood-proof door and window, the device comprising: The main structure 100 includes a door frame 103 installed on the floodgate and a floodgate 101 set on the door frame 103. The floodgate 101 is provided with an inner door body 102, and the inner door body 102 is provided with an equipment cavity 102a and a sealing cavity 102b. The drive mechanism 200 is located inside the inner door body 102. The drive mechanism 200 includes a first drive rod 201, a rotating wheel 203, a rotating block 204 and a connecting rod 205. The first drive rod 201 is rotatably connected to the inside of the equipment cavity 102a through a bearing. The rotating wheel 203 is connected to the outside of the first drive rod 201. Multiple rotating blocks 204 are connected to the outside of the rotating wheel 203. The end of the rotating block 204 away from the rotating wheel 203 is connected to the connecting rod 205 through a bearing. A sealing mechanism 300 is disposed inside the sealing cavity 102b. The sealing mechanism 300 includes a sealing plate 301 disposed inside the sealing cavity 102b, and a sealing block 302 is provided on the side of the sealing plate 301. The floodgate is equipped with a floodgate 101 for staff access, facilitating quick entry and exit and ensuring the floodgate remains closed unless absolutely necessary, thus enabling it to effectively prevent flooding. Secondly, a sealing mechanism 300 is added to the floodgate 101. This mechanism replaces the damaged floodgate 104, providing a sealed flood defense. Simultaneously, the sealing plate 301 within the sealing mechanism 300 withstands the impact and pressure of floodwaters and the tension of the pull rod 301d. Under the action of the sealing strip 301b and the sealing groove 307, the sealing plate 301 is tightly attached to the sealing cavity 102b and the sealing effect of the sealing plate 301 is ensured. Finally, the first drive rod 201, the rotating wheel 203, the rotating block 204, the connecting rod 205, the second drive rod 206 and the moving rod 206a are set to enable the inner door body 102 to be quickly engaged and fixed with the door frame 103, and to limit the position of the sealing plate 301 in the lateral direction, so as to prevent the sealing plate 301 from moving and causing the sealing and flood prevention effect to decrease.

[0025] Example 2 Reference Figure 1-15 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: multiple rotating blocks 204 are evenly distributed about the axis of the rotating wheel 203; multiple second driving rods 206 and moving rods 206a are provided in the equipment cavity 102a; the second driving rods 206 are symmetrically arranged vertically about the axis of the first driving rod 201; the moving rods 206a are symmetrically arranged horizontally about the axis of the first driving rod 201; the ends of multiple connecting rods 205 away from the rotating blocks 204 are respectively connected to the second driving rods 206 and the moving rods 206a; and one end of the first driving rod 201 protrudes from the outer surface of the inner door body 102 and is connected to a handwheel 202.

[0026] Installing flood control facilities at access points and busbar tunnels in each power station is an urgent and necessary measure to ensure that the powerhouse does not flood in extreme situations such as mudslides caused by localized heavy rain, resulting in river blockages and abnormally high water levels. This is crucial for improving flood control and disaster prevention capabilities in extreme circumstances. During normal use of floodgates, floodgates can be equipped with floodgate doors 101 for personnel access. This reduces the need for personnel to fully open the floodgates when entering or leaving the power station, ensuring that the floodgates remain closed unless necessary. This prevents situations where the floodgates cannot be closed in time during extreme weather or abnormally high water levels, which could lead to flooding of the powerhouse and damage to the power station equipment.

[0027] When the flood comes, the floodgate 101 is closed outwards. Then, the handwheel 202 drives the second drive rod 206 and the rotating wheel 203 to rotate. The rotating wheel 203 drives the second drive rod 206 or the moving rod 206a to move away from the rotating wheel 203 through the rotating block 204 and the connecting rod 205. At this time, the moving rod 206a drives multiple side fixing rods 208a to move through the moving plate 207a, so that the side fixing rods 208a are inserted into the side hole 103a on the door frame 103 through the opening 209a.

[0028] Compared to Embodiment 1, further, a pressing plate 207 is connected to the bottom end of the second drive rod 206 located below the rotating wheel 203. Multiple lower fixing rods 208 are connected to the lower surface of the pressing plate 207. Multiple through holes 209 communicating with the equipment cavity 102a are connected to the lower surface of the inner door body 102. The cross-sectional size of the through holes 209 matches the cross-sectional size of the lower fixing rods 208. A moving plate 207a is connected to the end of the moving rod 206a away from the rotating wheel 203. The moving plate 207a is located away from the moving rod 206a. The side connection includes multiple side fixing rods 208a. The inner door 102 has multiple openings 209a on both sides communicating with the equipment cavity 102a. The cross-sectional size of the openings 209a matches the cross-sectional contour of the side fixing rods 208a. The inner side of the door frame 103 near the bottom has multiple bottom holes 103b, which correspond to the positions of the through holes 209. The interior of the door frame 103 has multiple side holes 103a on both sides, which correspond to the positions of the openings 209a.

[0029] At the same time, the second drive rod 206 located below the rotating wheel 203 drives the pressing plate 207 and the lower fixing rod 208 to move down, so that the bottom end of the lower fixing rod 208 is inserted into the bottom hole 103b on the door frame 103 through the through hole 209. This allows the inner door 102 to engage with the door frame 103 through the lower fixing rod 208, the side fixing rod 208a, the side hole 103a, and the bottom hole 103b, thus completing the engagement and fixation of the flood control door 101 and the inner door 102. At this time, the inner door 102 is completely embedded in the door frame 103, forming a flood control and sealing effect.

[0030] The remaining structure is the same as that in Example 1.

[0031] Example 3 Reference Figure 1-15This is the third embodiment of the present invention, which differs from the second embodiment in that: a flood control window 104 is provided on the flood control door 101, and the flood control window 104 penetrates the inner door body 102 and communicates with the sealing cavity 102b. A U-shaped sealing groove 307 is provided on the inner wall of the sealing cavity 102b away from the flood control door 101. A sealing strip 301b that matches the sealing groove 307 is connected to the side of the sealing plate 301 near the sealing groove 307. Two limiting holes 301c are provided on the lower surface of the sealing plate 301. The cross-sectional width of the limiting hole 301c is larger than the cross-sectional width of the limiting block 306. A T-shaped slider 301a is connected to the side of the sealing plate 301. A groove 302a is provided on the sealing block 302. The cross-sectional profile of the groove 302a matches the cross-sectional size of the slider 301a. A slot 308 communicating with the sealing cavity 102b is provided on the side of the inner door 102 away from the flood door 101. The slot 308 communicates with the flood window 104 and the sealing groove 307 respectively. A pull rod 301d is connected to the side of the sealing plate 301 away from the flood door 101. The surface of the pull rod 301d is threaded, and a fixing nut 301d-1 is connected to the pull rod 301d through threaded engagement.

[0032] Due to ventilation and heat dissipation needs, factories and power plants often have windows installed at lower positions. These lower-positioned windows are more vulnerable to floods and mudslides. Installing flood-proof windows on the outside of these windows can effectively reduce the risk of damage caused by floods and geological disasters. Flood-proof windows also need to have a certain level of impact resistance and sealing to withstand flood impacts. Existing windows only rely on tempered glass for protection. If a flood-proof window breaks during a flood, floodwater can pass directly through the floodgate 101 via the flood-proof window 104, causing flood control failure. To address this, the sealing plate 301 and sealing block 302 can be moved by pulling the rod 301d, causing the sealing plate 301 to completely seal the flood-proof window 104. At this time, the sealing strip 301b on the sealing plate 301 corresponds to the sealing groove 307. Then, the fixing nut 301d-1 is rotated, causing the fixing nut 301d-1 to... The inner door 102 moves and presses against the inner door 102, causing the pull rod 301d to move the sealing plate 301 towards the sealing groove 307, thereby allowing the sealing strip 301b to be inserted into the sealing groove 307, completing the sealing of the flood control window 104. At the same time, after the flood arrives, the side of the sealing plate 301 closest to the flood control door 101 comes into contact with the flood, causing the sealing plate 301 to be compressed by the flood, making the sealing strip 301b on the sealing plate 301 even tighter against the sealing groove 307. When the sealing plate 301 moves away from the flood control door 101, the sliding block 301a and the sliding groove 302a can limit the direction and distance of movement of the sealing plate 301. At the same time, during the lateral movement, the sealing block 302 moves, and the sealing block 302 can seal the sealing cavity 102b. This ensures that even if the flood control window 104 is broken by the flood, the sealing plate 301 can still block the flood, further improving the flood control effect of the power station.

[0033] Compared to Embodiment 2, the inner door body 102 further includes a lifting groove 102c communicating with the sealing cavity 102b. The lifting groove 102c is equipped with a lifting plate 303 for use therewith. The top of the second drive rod 206 located above the rotating wheel 203 extends into the lifting groove 102c and connects to the lower surface of the lifting plate 303. A connecting plate 305 is provided above the lifting plate 303. Multiple springs 304 are provided between the connecting plate 305 and the lifting plate 303. A limit block 306 is connected to the upper surface of the connecting plate 305, and the limit block 306 is symmetrically arranged about the center of the connecting plate 305. The top of the limit block 306 is provided with an inclined surface.

[0034] Then, when the rotating wheel 203 drives the second drive rod 206 located above the rotating wheel 203 to move via the rotating block 204 and the connecting rod 205, the second drive rod 206 drives the connecting plate 305 and the limiting block 306 to move upward via the lifting plate 303, so that the top of the limiting block 306 extends into the sealing cavity 102b. During the movement, the sealing plate 301 contacts the inclined surface of the limiting block 306 and squeezes the limiting block 306. After the sealing plate 301 completely seals the flood control window 104, the position of the limiting hole 301c corresponds to the position of the limiting block 306, so that the connecting plate 305 drives the limiting block 306 to move upward under the action of the spring force of the spring 304, so that the top of the limiting block 306 is inserted into the limiting hole 301c. Inside c, the horizontal position of the sealing plate 301 is fixed, while ensuring that the sealing strip 301b on the sealing plate 301 corresponds to the position of the sealing groove 307. After the flood, the handwheel 202 can be turned in the opposite direction to separate the side fixing rod 208a and the lower fixing rod 208 from the side hole 103a and the bottom hole 103b, opening the flood gate 101. At the same time, the second drive rod 206 drives the lifting plate 303, the connecting plate 305 and the limiting block 306 to move down, releasing the horizontal restriction of the sealing plate 301. Then, the fixing nut 301d1-1 is loosened, and after the sealing plate 301 separates from the sealing groove 307, the sealing plate 301 is pulled into the sealing cavity 102b by the pull rod 301d, completing the opening of the flood window 104.

[0035] The remaining structure is the same as that in Example 2.
