Description

Technical Field

[0001] This invention relates to flood control equipment technology, specifically to a fully automatic pneumatically driven flap-type flood control and water-blocking device. Background Technology

[0002] Currently, flood control and water-blocking devices widely used in public places and underground spaces mainly include hydraulic, airbag, and flap-type devices. These existing devices have several shortcomings in practical application. Firstly, their deployment is highly dependent on manual or electric power. Manually operated barriers often require multiple workers to move and assemble them, which is not only time-consuming and labor-intensive but also inefficient and difficult to respond quickly in emergency flood situations. While electrically driven devices are more convenient to operate, the power system is prone to failure or partial power outages during severe weather conditions in flood season. Once the power is cut off, the barriers cannot be deployed properly due to the lack of power. Secondly, most existing flood control barriers are fixed structures without folding and storage capabilities. They need to be disassembled and stored after use, which is not only cumbersome but also occupies a large storage space. Especially in public places where space is already limited, the long-term stacking of large barrier components can seriously affect daily passage and aesthetics.

[0003] Given the obvious shortcomings of the existing flood control and water barrier devices in terms of deployment method, power dependence, and storage convenience, it is necessary to improve the structure of the existing flood control and water barrier devices to provide a new flood control and water barrier solution that does not rely on electricity, can be automatically deployed, and can be folded and stored. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic pneumatically driven flap-type flood control and water barrier device to solve the problems of existing flood control and water barrier devices that rely on electricity for deployment and are inconvenient to store.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic pneumatically driven flap-type flood control and water-blocking device, comprising:

[0006] Mounting slot with an opening at the top;

[0007] A cover plate assembly, connected to the mounting groove, for covering the upper opening of the mounting groove;

[0008] A water-blocking assembly is installed on the mounting groove and located between the mounting groove and the cover plate assembly, including a first baffle hinged to the mounting groove, a hinge plate hinged to the first baffle, and a second baffle hinged to the hinge plate.

[0009] A pneumatic assembly, installed on the first baffle, is used to open the water-blocking assembly. It includes a pneumatic telescopic rod fixedly installed on the first baffle, a push block fixedly installed at the end of the pneumatic telescopic rod, and a support rod fixedly installed on the side wall of the first baffle. The side wall of the push block is hinged to a support rod, and a sliding groove is provided on the support rod, which is inserted into the sliding groove.

[0010] A stop block is installed on the mounting groove, and the end of the stop block facing the push block is provided with a gradually changing slide from horizontal to vertical.

[0011] Preferably, both the first baffle and the second baffle have grooves on their sidewalls, and the hinge plate is embedded in the grooves to cover the joint between the first baffle and the second baffle. An extension plate is provided on the outer side of the second baffle near the hinge plate, and the extension plate rotates to cover the joint between the hinge plate and the baffle.

[0012] Preferably, the first baffle has an L-shaped cross-section, and the lower end of the first baffle is hinged to the mounting groove.

[0013] Preferably, the cover plate assembly includes a slide rail hinged to the mounting groove and a slide plate slidably connected to the slide rail on the side near the mounting groove. The slide plate has a groove on the side near the mounting groove, and a short rod is connected to one end of the slide plate near the water-blocking assembly. A first cover plate is hinged to one side of the slide rail, and a second cover plate is hinged to one side of the first cover plate. A hook for hooking the short rod is installed on the second cover plate.

[0014] Preferably, both the first cover plate and the second cover plate are triangular in shape, and the hypotenuses of the first cover plate and the second cover plate are hinged to each other.

[0015] Preferably, the first baffle is connected to a side baffle, and a transmission telescopic rod that cooperates with the pneumatic telescopic rod is also connected to the first baffle. The transmission telescopic rod includes a sleeve fixedly installed on the first baffle, a first push rod slidably inserted into one end of the sleeve, and a second push rod slidably inserted into the other end of the sleeve. A first spring is provided between the first push rod and the second push rod, and a second spring is sleeved on the second push rod. The end of the first push rod abuts against the push block, and the end of the second push rod abuts against the side baffle.

[0016] Preferably, the side wall of the side baffle is connected with a rubber sealing strip.

[0017] Preferably, an auxiliary pulling assembly is installed on the mounting groove. The auxiliary pulling assembly includes a mounting shell fixedly installed on the mounting groove, a pull rod slidably inserted into the mounting shell, and a third spring sleeved on the pull rod. The third spring is pre-compressed, with one end abutting against the side wall of the pull rod and the other end abutting against the inner wall of the mounting shell.

Through the precise mechanical linkage design of the push block, support rod, strut, and the gradually changing slide on the block, the pneumatic telescopic rod can sequentially drive the first baffle, hinge plate, and second baffle to flip smoothly when extended. The entire process requires no manual handling or assembly, achieving a rapid response with one-button start and automatic flap flipping, greatly reducing labor and time costs. Furthermore, in the non-working state, all baffles can be folded and stored in the installation slot and covered by the cover plate assembly. The device is flush with the ground, occupying no extra ground space and not affecting daily passage and overall aesthetics in public places, solving the problems of cumbersome disassembly and assembly and space occupation of traditional baffles. The device has a compact structure, with smooth cooperation between all hinges and limiting components, resulting in stable and shock-free operation. Compared with hydraulic systems, pneumatic drive is cleaner and has no risk of oil leakage. It is easy to maintain and has a long service life, making it very suitable for long-term deployment in various key flood control locations such as underground garages, subway entrances and exits, and shopping malls. It has extremely high practical and promotional value. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] As attached Figure 1 To be continued Figure 9 As shown:

[0033] Example:

[0034] This invention provides a fully automatic pneumatically driven flap-type flood control and water-blocking device, comprising:

[0035] Mounting slot 1 has an opening at the top, allowing it to be recessed and installed on the ground;

[0036] The cover plate assembly 2 is connected to the mounting groove 1 and is used to cover the upper opening of the mounting groove 1 so that the upper end of the mounting groove 1 remains flat.

[0037] A water-blocking assembly is installed on the mounting groove 1 and located between the mounting groove 1 and the cover plate assembly 2. It includes a first baffle 3 hinged to the mounting groove 1, a hinge plate 4 hinged to the first baffle 3, and a second baffle 5 hinged to the hinge plate 4. The first baffle 3, the hinge plate 4, and the second baffle 5 are folded and stored in the mounting groove 1. When flood prevention and water blocking are required, the first baffle 3, the hinge plate 4, and the second baffle 5 are unfolded vertically to form a water-blocking wall.

[0038] A pneumatic assembly, installed on the first baffle 3, is used to open the water-blocking assembly. It includes a pneumatic telescopic rod 6 fixedly installed on the first baffle 3, a push block 7 fixedly installed at the end of the pneumatic telescopic rod 6, and a support rod 8 fixedly installed on the side wall of the first baffle 3. A support rod 9 is hinged to the side wall of the push block 7. A sliding groove is provided on the support rod 9, and the support rod 8 is inserted into the sliding groove.

[0039] The stop block 10 is installed on the mounting groove 1, and the end of the stop block 10 facing the push block 7 is provided with a gradually changing slide from horizontal to vertical.

[0040] When it is necessary to deploy the water-blocking assembly to form a water-blocking wall, the pneumatic telescopic rod 6 is activated. The pneumatic telescopic rod 6 drives the push block 7 to move. The push block 7 slides along the gradual slide on the stop block 10. The stop block 10 forces the push block 7 to gradually change from a horizontal position to a vertical position. As the position of the push block 7 changes, the push block 7 will also drive the first baffle 3 to rotate from a horizontal position to a vertical position. Moreover, the pneumatic telescopic rod 6 will also drive the support rod 9 to rotate around the support rod 8. The upper end of the rotating support rod 9 will successively abut the hinge plate 4 and the second baffle 5, thereby supporting the first baffle 3, the hinge plate 4 and the second baffle 5 vertically.

[0041] As can be seen from the above, by using pneumatic components as the sole power source, the dependence on electricity is eliminated. Even in the event of a power outage or circuit failure during the flood season, the water-blocking components can still be automatically deployed by air pressure drive, effectively overcoming the fatal flaw of traditional electric drive devices failing during power outages and ensuring the absolute reliability of flood control response. Through the precise mechanical linkage design of the push block 7, support rod 9, support rod 8 and the gradual slide on the block 10, when the pneumatic telescopic rod 6 extends, it can sequentially drive the first baffle 3, hinge plate 4 and second baffle 5 to flip up smoothly. The entire process does not require manual handling or assembly, realizing a rapid response of one-button start and automatic flipping, greatly reducing labor and time costs. Furthermore, in the normal non-working state, all baffles can be folded and stored in the installation slot 1 and covered by the cover plate component 2. The device is flush with the ground, which does not occupy additional ground space, nor does it affect the daily passage and overall aesthetics of public places, solving the problems of cumbersome disassembly and assembly and space occupation of traditional baffles. The device has a compact structure, with smooth cooperation between all hinges and limiting components, resulting in stable and shock-free operation. Compared with hydraulic systems, pneumatic drive is cleaner and has no risk of oil leakage. It is easy to maintain and has a long service life, making it very suitable for long-term deployment in various key flood control locations such as underground garages, subway entrances and exits, and shopping malls. It has extremely high practical and promotional value.

[0042] To prevent water leakage from the gap between the baffle and the hinge plate 4, the side walls of the first baffle 3 and the second baffle 5 are both provided with grooves. The hinge plate 4 is embedded in the grooves to cover the joint between the first baffle 3 and the second baffle 5. An extension plate is provided on the outer side of the second baffle 5 near the hinge plate 4. The extension plate rotates to cover the joint between the hinge plate 4 and the baffle.

[0043] The first baffle 3 has an L-shaped cross-section, and the lower end of the first baffle 3 is hinged to the mounting groove 1. When the first baffle 3 is vertical, the L-shaped edge of the first baffle 3 will contact the ground, so that the first baffle 3 stands stably on the ground.

[0044] The cover plate assembly 2 includes a slide rail 21 hinged to the mounting groove 1 and a slide plate 22 slidably connected to the slide rail 21 on the side near the mounting groove 1. The slide plate 22 has a groove on the side near the mounting groove 1, and a short rod 23 is connected to one end of the slide plate 22 near the water-blocking assembly. A first cover plate 24 is hinged to one side of the slide rail 21, and a second cover plate 25 is hinged to one side of the first cover plate 24. A hook rod 51 for hooking the short rod 23 is installed on the second baffle 5. The first cover plate 24 and the second cover plate 25 are both triangular in shape, and the hypotenuses of the first cover plate 24 and the second cover plate 25 are hinged to each other.

[0045] When the support rod 9 rotates to support the second baffle 5, the second baffle 5 will insert the hook rod 51 into the groove on the side of the slide plate 22 during the rotation process. As the second baffle 5 continues to rotate, the hook rod 51 continues to slide along the groove and is hooked. Then, the rotating second baffle 5 drives the slide plate 22 and the slide rail 21 to rotate and extend through the hook rod 51 and the short rod 23. The rotating slide rail 21 will drive the first cover plate 24 and the second cover plate 25 to move upward. The first cover plate 24 and the second cover plate 25 naturally droop under the action of gravity. The slide rail 21 and the first cover plate 24 on both sides form a pointed wedge, which is used to split the water flow rushing towards the water barrier, so that the water flow is separated and the impact of the accumulated water waves on the water barrier is reduced.

[0046] The first baffle 3 has a side baffle 31 connected to its side wall. The first baffle 3 is also connected to a transmission telescopic rod 11 that cooperates with the pneumatic telescopic rod 6. The transmission telescopic rod 11 includes a sleeve 111 fixedly installed on the first baffle 3, a first push rod 112 slidably inserted into one end of the sleeve 111, and a second push rod 113 slidably inserted into the other end of the sleeve 111. A first spring 114 is provided between the first push rod 112 and the second push rod 113. A second spring 115 is sleeved on the second push rod 113. The end of the first push rod 112 abuts against the push block 7, and the end of the second push rod 113 abuts against the side baffle 31.

[0047] As can be seen from the above, when the pneumatic telescopic rod 6 drives the push block 7 to move, the moving push block 7 will also push the first push rod 112. The first push rod 112 pushes and compresses the first spring 114. The compressed first spring 114 applies pressure to the second push rod 113. Under the action of this pressure, the second push rod 113 compresses the second spring 115 and extends out of the sleeve 111. The outwardly extended second push rod 113 pushes the side baffle 31. After the side baffle 31 rotates, it fits against the wall on the side of the mounting groove 1, sealing the gap between the baffle and the wall, and improving the water-resistant sealing performance of the first baffle 3 and the second baffle 5.

[0048] To further improve the sealing performance of the side baffle 31, a rubber sealing strip is connected to the side wall of the side baffle 31. The sealing strip can close the gap between the side baffle 31 and the wall.

[0049] To prevent the rotating support rod 9 from failing to support the first baffle 3 and the second baffle 5, an auxiliary pulling assembly 12 is installed on the mounting groove 1. The auxiliary pulling assembly 12 includes a mounting shell 121 fixedly installed on the mounting groove 1, a pull rod 122 slidably inserted into the mounting shell 121, and a third spring 123 sleeved on the pull rod 122. The third spring 123 is pre-compressed, with one end abutting against the side wall of the pull rod 122 and the other end abutting against the mounting shell 122. The inner wall of the shell 121 abuts against the second baffle 5. An elastic cable 13 is connected between the end of the pull rod 122 and the second baffle 5. The compressed third spring 123 applies a pulling force to the pull rod 122. The pull rod 122 pulls the second baffle 5 through the elastic cable 13. When the pneumatic telescopic rod 6 extends and drives the support rod 9 to rotate and flip the first baffle 3 and the second baffle 5, the pull rod 122 can help the second baffle 5 to flip by pulling the second baffle 5, thus preventing the support rod 9 from getting stuck between the first baffle 3 and the second baffle 5.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
