Description

Technical Field

[0001] This utility model relates to the field of stainless steel floating roof technology, specifically a fully welded stainless steel liquid-immersed honeycomb internal floating roof. Background Technology

[0002] An internal floating roof is a sealing and covering device installed inside a liquid storage tank. It mainly consists of the floating roof body and sealing components. By floating above the liquid surface, it can isolate the liquid from contact with air, reduce the evaporation loss of volatile liquids such as gasoline and diesel, and reduce the concentration of flammable gases in the storage tank, thereby improving storage safety. It is currently widely used in petrochemical, grain and oil storage and other fields, and is a practical device that balances economy and safety.

[0003] Currently, existing internal floating roofs typically consist of multiple metal pontoons welded directly to the bottom surface. While this structure offers strong stability, it is difficult to disassemble and replace individual pontoons when they are damaged or deformed. The entire structure must be disassembled and repaired, which is not only time-consuming and labor-intensive but also affects the continuous operating efficiency of the storage tank. Therefore, we provide a fully welded stainless steel liquid-immersed honeycomb internal floating roof. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully welded stainless steel liquid-immersed honeycomb internal floating roof.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully welded stainless steel liquid-immersed honeycomb internal floating roof, comprising a floating plate, the outer edge of which is covered with a filler and multiple sealing rings, the inner edge of which is provided with multiple anti-rotation sleeves, a honeycomb bracket fixedly connected to the bottom outer wall of the floating plate, multiple sets of mounting slide rails fixedly connected to the inner wall of the honeycomb bracket, multiple limiting grooves on both sides of the outer wall of the mounting slide rail, multiple levers slidably connected to both sides of the outer wall of the mounting slide rail, and a snap-fit ​​metal part slidably connected to the center of the inner cavity of the mounting slide rail, the outer wall of the snap-fit ​​metal part having an oblique groove, and a limiting rod at the top of the inner cavity of the oblique groove, multiple floats inside the honeycomb bracket, multiple mounting brackets fixedly connected to both sides of the outer wall of the floats, a mounting slot on one side of the outer wall of the mounting bracket, and multiple compression springs in the inner cavity of the mounting slide rail.

[0006] As described above, the bottom outer wall of the mounting slide rail is connected through to the top of the inner cavity of the mounting frame, and the bottom outer wall of the mounting slide rail is slidably connected to the top of the inner cavity of the mounting frame.

[0007] As described above, one end of the compression spring abuts against the outer wall of the snap-fit ​​metal part, and the other end of the compression spring abuts against one side of the inner wall of the mounting slide rail.

[0008] As described above, the outer wall of the snap-fit ​​metal part is tightly fitted to the inner wall of the mounting slide rail, and the outer wall of the snap-fit ​​metal part is slidably connected to the inner wall of the mounting slide rail.

[0009] As described above, one side of the outer wall of the snap-fit ​​metal part extends out of the outer wall of the mounting slide rail, and the outer wall of the snap-fit ​​metal part is engaged with the inner wall of the mounting slot. The top surface of one side of the snap-fit ​​metal part and the top of the inner wall of the mounting slot are both flat, and the bottom outer wall of the snap-fit ​​metal part is provided with a slope.

[0010] As described above, the outer wall of the lever is tightly fitted to the inner wall of the limiting slide groove, and the outer wall of the lever is slidably connected to the top of the inner side of the limiting slide groove. The inner side of the limiting slide groove is interconnected with the inner side of the mounting slide rail, and the multiple levers are respectively fixedly connected to the two ends of the limiting rod.

[0011] As described above, the limiting rod is located at the top of the inclined groove cavity, the outer wall of the limiting rod is in close contact with the inner wall of the inclined groove, and the outer wall of the limiting rod is slidably connected to the inner wall of the inclined groove, and the outer wall of the top of the float abuts against the bottom surface of the float.

[0012] Compared with existing technologies, this all-welded stainless steel liquid-immersed honeycomb internal floating roof has the following advantages:

[0013] I. This utility model utilizes the cooperation of a limiting rod and an inclined groove to pull down the levers on both sides of the mounting slide rail. The limiting rod will squeeze the inner wall of the inclined groove, causing the snap-fit ​​metal part to retract into the mounting slide rail and finally exit the mounting slot, thus releasing the lock on the float. At the same time, it is only necessary to align the outer mounting bracket of the new float with the mounting slide rail and push it into the honeycomb bracket to realize the disassembly and replacement of a single float, which greatly shortens the maintenance time.

[0014] II. This utility model utilizes the structural characteristics and reset capability of a compression spring. After the float is disassembled or replaced, the spring, due to its own reset capability, pushes the snap-fit ​​metal part out again, accurately embedding it into the mounting slot, and installing the float inside the honeycomb bracket.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-7 As shown, this utility model provides a technical solution for a fully welded stainless steel liquid-immersed honeycomb internal floating roof: A fully welded stainless steel liquid-immersed honeycomb internal floating roof includes a floating plate 1, with a filler 101 sleeved around the outer edge of the floating plate 1, and multiple sealing rings 102 sleeved around the outer edge of the floating plate 1. Multiple anti-rotation sleeves 103 are provided on the inner edge of the floating plate 1. A honeycomb bracket 2 is fixedly connected to the outer wall of the bottom end of the floating plate 1, and multiple sets of installation slide rails 201 are fixedly connected to the inner wall of the honeycomb bracket 2. Multiple limiting grooves 2 are opened on both sides of the outer wall of the installation slide rails 201. 02. Multiple levers 203 are slidably connected to both sides of the outer wall of the mounting slide rail 201, and a snap-fit ​​metal part 204 is slidably connected to the center of the inner cavity of the mounting slide rail 201. The outer wall of the snap-fit ​​metal part 204 is provided with an inclined groove 205, and a limiting rod 206 is provided at the top of the inner cavity of the inclined groove 205. Multiple floats 207 are provided inside the honeycomb bracket 2, and multiple mounting brackets 208 are fixedly connected to both sides of the outer wall of the floats 207. A mounting slot 209 is provided on one side of the outer wall of the mounting bracket 208. Multiple compression springs 2010 are provided in the inner cavity of the mounting slide rail 201.

[0026] By utilizing the cooperation between the limiting rod 206 and the inclined groove 205, the levers 203 on both sides of the mounting slide rail 201 can be pulled down, causing the outer wall of the limiting rod 206 to press against the inner wall of the inclined groove 205, thus releasing the locking of the snap-fit ​​metal part 204 onto the float 207. At the same time, simply align the outer mounting bracket 208 of the new float 207 with the mounting slide rail 201 and push it into the honeycomb bracket 2 to achieve the disassembly and replacement of a single float 207.

[0027] like Figure 5 As shown, the bottom outer wall of the mounting slide rail 201 is connected through to the top of the inner cavity of the mounting bracket 208, and the bottom outer wall of the mounting slide rail 201 is slidably connected to the top of the inner cavity of the mounting bracket 208.

[0028] The mounting bracket 208, by passing through the bottom outer wall of the mounting slide rail 201 and sliding along it, can prevent lateral displacement between the mounting bracket 208 and the mounting slide rail 201, and at the same time constrain the movement trajectory of the mounting bracket 208 inside the honeycomb bracket 2.

[0029] like Figure 7 As shown above, one end of the compression spring 2010 abuts against the outer wall of the snap-fit ​​metal part 204, and the other end of the compression spring 2010 abuts against one side of the inner wall of the mounting slide rail 201.

[0030] The compression spring 2010, through its own structural characteristics, continuously acts on the snap-fit ​​metal part 204, providing it with a continuous thrust. When the float 207 is installed in place, the compression spring 2010 can push the snap-fit ​​metal part 204 to automatically snap into the mounting slot 209 of the mounting bracket 208.

[0031] like Figure 6 As shown, the outer wall of the snap-fit ​​metal part 204 is tightly fitted to the inner wall of the mounting slide rail 201, and the outer wall of the snap-fit ​​metal part 204 is slidably connected to the inner wall of the mounting slide rail 201.

[0032] The outer wall of the snap-fit ​​metal part 204 fits tightly against the inner wall of the mounting slide rail 201, which can prevent the snap-fit ​​metal part 204 from sliding smoothly along its inner wall when it is inside the mounting slide rail 201 due to the gap between the snap-fit ​​metal part 204 and the mounting slide rail 201.

[0033] like Figure 6 As shown, one side of the outer wall of the snap-fit ​​metal part 204 extends out of the outer wall of the mounting slide rail 201, and the outer wall of the snap-fit ​​metal part 204 is engaged with the inner wall of the mounting slot 209. The top surface of one side of the snap-fit ​​metal part 204 and the top of the inner wall of the mounting slot 209 are both flat, and the bottom outer wall of the snap-fit ​​metal part 204 is provided with a slope.

[0034] The flat structure at the top of the snap-fit ​​metal part 204 and the mounting slot 209 makes the two fit more tightly, preventing the snap-fit ​​metal part 204 from accidentally falling off due to the swaying of the float 207 caused by the tank.

[0035] like Figure 5 As shown, the outer wall of the lever 203 is tightly fitted with the inner wall of the limiting slide groove 202, and the outer wall of the lever 203 is slidably connected to the top of the limiting slide groove 202. The inside of the limiting slide groove 202 is interconnected with the inside of the mounting slide rail 201. Multiple levers 203 are respectively fixedly connected to the ends of the limiting rod 206.

[0036] The tight fit between the lever 203 and the limiting slide 202 can prevent deviation during operation, ensuring that the lever 203 slides along a fixed trajectory. The lever 203 is fixed to both ends of the limiting rod 206, so that the movement of the lever 203 can directly drive the limiting rod 206 to move.

[0037] like Figure 7 As shown, the limiting rod 206 is located at the top of the inner cavity of the inclined groove 205. The outer wall of the limiting rod 206 is in close contact with the inner wall of the inclined groove 205, and the outer wall of the limiting rod 206 is slidably connected to the inner wall of the inclined groove 205. The outer wall of the top of the float 207 abuts against the bottom surface of the float 1.

[0038] The inclined inner wall structure of the inclined groove 205 can convert the movement of the limiting rod 206 into the horizontal movement of the snap-fit ​​metal part 204. When the limiting rod 206 slides along the trajectory of the limiting slide groove 202, the guiding effect of the inclined inner wall of the inclined groove 205 can force the snap-fit ​​metal part 204 to move horizontally, ensuring that it can completely exit or snap into the mounting slot 209.

[0039] Working principle: The mounting bracket 208 slides along the bottom outer wall of the mounting slide rail 201, preventing lateral displacement between the mounting bracket 208 and the mounting slide rail 201. It also constrains the movement trajectory of the mounting bracket 208 within the honeycomb support 2. The compression spring 2010, through its structural characteristics, continuously acts on the locking metal part 204, providing it with a continuous thrust. When the float 207 is installed in place, the compression spring 2010 pushes the locking metal part 204 to automatically engage with the mounting slot 209 of the mounting bracket 208. The outer wall of the locking metal part 204 fits tightly against the inner wall of the mounting slide rail 201, preventing gaps between the locking metal part 204 and the mounting slide rail 201, which would otherwise cause the locking metal part 204 to slide smoothly along the inner wall of the mounting slide rail 201. The planar structure at the top of the metal part 204 and the mounting slot 209 makes the two fit more tightly, preventing the metal part 204 from accidentally falling off due to the swaying of the float 207 caused by the tank. The tight fit between the lever 203 and the limiting slide 202 can prevent deviation during operation, ensuring that the lever 203 slides along a fixed trajectory. The lever 203 is fixed to both ends of the limiting rod 206, so that the movement of the lever 203 can directly drive the limiting rod 206 to move. The inclined structure of the inner wall of the inclined groove 205 can convert the movement of the limiting rod 206 into the horizontal movement of the metal part 204. When the limiting rod 206 slides along the trajectory of the limiting slide 202, the guiding effect of the inclined inner wall of the inclined groove 205 can force the metal part 204 to move horizontally, ensuring that it can completely exit or enter the mounting slot 209.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
