Description

Technical Field

[0001] This utility model relates to the field of water storage equipment technology, and in particular to a BDF prefabricated underground water tank. Background Technology

[0002] Water storage equipment refers to various containers or devices used to store water resources. It aims to meet the needs of water collection, storage, regulation and supply in different scenarios, and ensure the rational use and stable supply of water resources. Among them, the BDF prefabricated underground water tank is a water storage device made by stamping standard modules of water tank after combining SUS304 stainless steel plate and galvanized steel plate through a special process. It is assembled on site with bolts and is commonly known as prefabricated water tank, underground water tank, or bolted water tank.

[0003] Currently, the ventilation caps of prefabricated underground water tanks on the market are designed with a fixed height, which cannot be adjusted. This design limitation means that in practical applications, the height of the ventilation cap cannot be appropriately adjusted according to the specific conditions on site, which greatly affects the ventilation effect of the water tank and prevents it from reaching the ideal state. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing prefabricated underground water tank ventilation cap is designed with a fixed height, which cannot be adjusted, thus affecting the ventilation effect inside the water tank in actual application. To this end, we propose a BDF prefabricated underground water tank.

[0005] To achieve the above objectives, this application adopts the following technical solution: A BDF prefabricated underground water tank, comprising a prefabricated underground water tank body: a ventilation rod is installed at the top of the prefabricated underground water tank body, an expansion groove is provided inside the ventilation rod, a ventilation cap is slidably connected inside the expansion groove, a first sliding groove is provided at both ends of the surface of the ventilation cap, a square groove is provided at both ends of the surface of the ventilation rod, a connecting block is fixedly connected at both ends of the surface of the ventilation rod, a limit block is slidably connected to both sides of the connecting block, a plurality of limit grooves are provided on both sides of the first sliding groove, and the surface of one end of the limit block is slidably connected to the inside of the limit groove.

[0006] Preferably, a second sliding groove is provided on both sides of the telescopic groove, and a second sliding block is fixedly connected to both sides of the ventilation cap, with the surface of the second sliding block slidably connected to the interior of the second sliding groove.

[0007] Preferably, three rotating wheels are installed on one side of the second sliding block, and the surface of the rotating wheels is rotatably connected to one side of the interior of the second sliding groove.

[0008] Preferably, a square plate is fixedly connected inside the connecting block, and three springs are fixedly connected to both sides of the square plate, with the other end of the springs fixedly connected to the limiting block.

[0009] Preferably, the top and bottom of the limiting block are provided with guide grooves, and the top and bottom of both sides of the connecting block are fixedly connected with guide blocks, and the surface of the guide block is slidably connected to the inside of the guide groove.

[0010] Preferably, a shielding pad is installed on the top of the ventilation rod.

[0011] Preferably, scale marks are provided at both ends of the surface of the ventilation cap.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pressing the limiting block, one end of the limiting block moves out of the limiting groove and back into the first sliding groove, thereby releasing the limiting position of the ventilation cap inside the telescopic groove. At this time, the ventilation cap can be moved to adjust its height. After adjustment, the pressing of the limiting block is released, allowing one end of the limiting block to return to the limiting groove, thus restoring the limiting position of the ventilation cap inside the telescopic groove. Through this setting, the height of the ventilation cap can be adjusted according to the site conditions to optimize ventilation performance. At the same time, the height-adjustable ventilation cap can be adjusted to a suitable height according to the actual terrain, ensuring that the ventilation cap is not affected by the terrain and can perform its ventilation function normally.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a BDF prefabricated underground water tank, including a prefabricated underground water tank body 1; a ventilation rod 2 is installed at the top of the prefabricated underground water tank body 1, the ventilation rod 2 has an internal telescopic groove 3, a ventilation cap 4 is slidably connected inside the telescopic groove 3, a first sliding groove 5 is opened at both ends of the surface of the ventilation cap 4, a square groove 6 is opened at both ends of the surface of the ventilation rod 2, a connecting block 7 is fixedly connected at both ends of the surface of the ventilation rod 2, a limit block 8 is slidably connected to both sides of the connecting block 7, a plurality of limit grooves 9 are opened on both sides of the first sliding groove 5, and the surface of one end of the limit block 8 is slidably connected to the inside of the limit groove 9, and can be opened by pressing... Move the limiting block 8 so that one end of the limiting block 8 moves out of the limiting groove 9 and back into the first sliding groove 5, thereby releasing the limiting position of the ventilation cap 4 inside the telescopic groove 3. At this time, the ventilation cap 4 can be moved to adjust its height. After adjustment, release the pressing of the limiting block 8 so that one end of the limiting block 8 returns to the limiting groove 9, and the ventilation cap 4 is again limited inside the telescopic groove 3. Through this setting, the height of the ventilation cap 4 can be adjusted according to the site conditions to optimize ventilation performance. At the same time, the height-adjustable ventilator can be adjusted to a suitable height according to the actual terrain to ensure that the ventilator is not affected by the terrain and can play a normal ventilation role.

[0023] Reference Figure 2 and Figure 3 As shown in this embodiment: a second sliding groove 10 is provided on both sides of the telescopic groove 3, and a second sliding block 11 is fixedly connected to both sides of the ventilation cap 4. The surface of the second sliding block 11 is slidably connected to the inside of the second sliding groove 10. By allowing the second sliding block 11 to slide inside the second sliding groove 10, the movement position of the ventilation cap 4 can be restricted, making the movement of the ventilation cap 4 more stable.

[0024] Reference Figure 3 As shown in this embodiment: three rotating wheels 12 are installed on one side of the second sliding block 11. The surface of the rotating wheels 12 is rotatably connected to one side of the interior of the second sliding groove 10. By setting the rotating wheels 12, the friction of the ventilation cap 4 when it moves inside the telescopic groove 3 can be effectively reduced, making the movement of the ventilation cap 4 smoother.

[0025] Reference Figure 5 As shown in this embodiment: a square plate 13 is fixedly connected inside the connecting block 7. Three springs 14 are fixedly connected to both sides of the square plate 13. The other end of the spring 14 is fixedly connected to the limiting block 8. By setting the spring 14, the elasticity of the spring 14 abuts against the limiting block 8. When the user releases the pressure on the limiting block 8, the elasticity of the spring 14 will abut against the limiting block 8, so that the limiting block 8 will automatically reset and enter the interior of the limiting groove 9, simplifying the operation process.

[0026] Reference Figure 5 As shown in this embodiment: guide grooves 15 are provided at the top and bottom of the limiting block 8, and guide blocks 16 are fixedly connected to the top and bottom of both sides of the connecting block 7. The surface of the guide block 16 is slidably connected to the inside of the guide groove 15. By moving the guide block 16 inside the guide groove 15, the movement of the limiting block 8 can be guided, so that the limiting block 8 moves along a predetermined route and avoids unnecessary deviation during movement.

[0027] Reference Figure 5 As shown in this embodiment: a shielding pad 17 is installed on the top of the ventilation rod 2. By setting the shielding pad 17, the gap between the ventilation rod 2 and the ventilation cap 4 can be shielded to prevent debris and sand from entering and affecting the normal operation of the equipment.

[0028] Reference Figure 3 As shown in this embodiment, scale marks 18 are provided at both ends of the surface of the ventilation cap 4. The accuracy and convenience of height adjustment are improved by setting scale marks 18.

[0029] Working principle: By pressing the limiting block 8, one end of the limiting block 8 moves out of the limiting groove 9 and back into the first sliding groove 5, thereby releasing the limitation of the ventilation cap 4 inside the telescopic groove 3. At this time, the ventilation cap 4 can be moved to adjust its height. After adjustment, releasing the pressing of the limiting block 8 allows one end of the limiting block 8 to return to the limiting groove 9, thus restoring the limitation of the ventilation cap 4 inside the telescopic groove 3. Through this setting, the height of the ventilation cap 4 can be adjusted according to the site conditions to optimize ventilation performance. At the same time, the height-adjustable ventilator can be adjusted to a suitable height according to the actual terrain, ensuring that the ventilator is not affected by the terrain and can perform its ventilation function normally. By sliding the second sliding block 11 inside the second sliding groove 10, the movement of the ventilation cap 4 can be restricted. The system is more stable. By setting the rotating wheel 12, the friction of the ventilation cap 4 when moving inside the telescopic groove 3 can be effectively reduced, making the movement of the ventilation cap 4 smoother. By setting the spring 14, the elasticity of the spring 14 abuts against the limit block 8. When the user releases the pressure on the limit block 8, the elasticity of the spring 14 will abut against the limit block 8, causing the limit block 8 to automatically reset and enter the interior of the limit groove 9, simplifying the operation process. By making the guide block 16 move inside the guide groove 15, the movement of the limit block 8 can be guided, allowing the limit block 8 to move along a predetermined route and avoiding unnecessary deviation during movement. By setting the shielding pad 17, the gap between the ventilation rod 2 and the ventilation cap 4 can be shielded to prevent debris and sand from entering and affecting the normal operation of the equipment. By setting the scale mark 18, the accuracy and convenience of height adjustment are improved.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
