Description

A water-blocking device with a top-pressure sealing structure Technical Field

[0001] This utility model relates to the technical field of water-blocking devices for specific sites for waterproofing and flood prevention, and in particular to a water-blocking device with a top-pressure sealing structure. Background Technology

[0002] Currently, the entrances and exits of various underground shopping malls and parking garages in major cities are typically 5 meters long and 2.5 meters high, with some garage doors being even longer and taller. Therefore, the equipment and devices used in these crucial flood-proof locations are extremely important and critical. Currently, many of these locations utilize flood control barriers or flood control roller shutters.

[0003] While various flood control barriers and roller shutters on the market offer relatively ideal flood control performance when subjected to low water levels and pressures below 1 meter, they become prone to leakage on the bottom and sides during sudden torrential rains that cause water accumulation exceeding 1 meter or submerging reservoir gates. The resulting water pressure can reach several tons or tens of tons, rendering these barriers ineffective at blocking water. This is because the barriers or roller shutters lack a secure seal between themselves and the frame or bottom frame. Summary of the Invention

[0004] The technical problem this invention aims to solve is the issue of water leakage between the flood control barrier or waterproof roller shutter and its frame and bottom frame during high water levels. A water-blocking device with a top-pressure sealing structure is proposed to address this problem.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0006] A water-blocking device with a top-pressure sealing structure includes:

[0007] One pressure-bearing component;

[0008] One clamping component;

[0009] A pressing drive assembly drives the pressing member to press the periphery of the water-blocking assembly onto the frame;

[0010] A clamping mounting assembly, wherein the clamping drive assembly is mounted on the clamping mounting assembly.

[0011] In a preferred embodiment of this utility model, the pressure-bearing component and the clamping mounting assembly are mounted on the same base or the same foundation.

[0012] In a preferred embodiment of this utility model, a gap is provided between the clamping member and the pressure-bearing member. When the water-blocking component blocks water, it is inserted into the gap and pressed onto the pressure-bearing member by the clamping member. When not blocking water, the clamping member is released and the water-blocking component is moved out of the gap, so that a channel is formed within the pressure-bearing member, the clamping member, and the clamping installation component.

[0013] In a preferred embodiment of this utility model, the pressure-bearing component, the clamping component, and the clamping installation assembly are all in the shape of a square.

[0014] In a preferred embodiment of the present invention, a soft pad with sealing stripes is provided on the side of the clamping member opposite to the pressure bearing member and on the side of the pressure bearing member opposite to the clamping member. The clamping member presses the water-blocking assembly onto the pressure bearing member through the soft pad with the sealing stripes.

[0015] In a preferred embodiment of the present invention, the clamping drive assembly includes an airbag and an inflator. The airbag is disposed between the clamping mounting assembly and the clamping member. The inflator is mounted on the clamping mounting assembly or the base and the inflator's inflation nozzle is connected to the airbag to inflate the airbag.

[0016] In a preferred embodiment of this utility model, the airbag is provided with a vent nozzle. Opening the vent nozzle allows the airbag to be deflated, and closing the vent nozzle allows the airbag to be inflated.

[0017] In a preferred embodiment of the present invention, the clamping drive assembly includes a plurality of lead screw clamping mechanisms. The driving part of the lead screw clamping mechanism is mounted on the clamping mounting assembly. The lead screw nut in the lead screw clamping mechanism is connected to the clamping member. The lead screw of the lead screw clamping mechanism drives the clamping member to move through the lead screw nut.

[0018] In a preferred embodiment of the present invention, the end of the lead screw away from the drive portion of the lead screw clamping mechanism is axially mounted on the pressure bearing member.

[0019] In a preferred embodiment of this utility model, the driving part of the lead screw clamping mechanism is a handwheel and a reduction gearbox or a motor and a reduction gearbox, and the handwheel or motor drives the lead screw to rotate through the reduction gearbox.

[0020] In a preferred embodiment of this utility model, the clamping drive assembly includes a plurality of hydraulic jacks, the hydraulic cylinders of the hydraulic jacks are mounted on the clamping mounting assembly, and the push rods of the hydraulic jacks are connected to the clamping member to drive the clamping member to move.

[0021] In a preferred embodiment of this utility model, the water-blocking component is a plurality of water-blocking plates or a water-blocking roller shutter.

[0022] In a preferred embodiment of the present invention, the roller shutter shaft of the water-blocking roller shutter is disposed on the top of the pressure-bearing member or the pressing and mounting assembly, and the roller shutter shaft is used for the raising and lowering of the water-blocking roller shutter.

[0023] In a preferred embodiment of this utility model, the roller shutter shaft of the water-blocking roller shutter is a manual roller shutter shaft or an electric roller shutter shaft.

[0024] By adopting the above technical solution, this utility model uses clamping ribs to press the water-blocking component tightly onto the pressure-bearing component, thus solving the problem of easy water leakage between existing flood control railings or waterproof roller shutters and their frames and bottom frames.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] Referring to Figure 1, a water-blocking device with a top-pressure sealing structure shown in the figure includes: a pressure-bearing component 100, a clamping component 200, a clamping drive assembly, and a clamping mounting assembly 300. The pressure-bearing component 100, the clamping component 200, and the clamping mounting assembly 300 are all U-shaped and perpendicular to the horizontal plane, and can be an integral structure or a separate structure. The pressure-bearing component 100, the clamping component 200, and the clamping mounting assembly 300 are made of steel plate or profiles.

[0033] The pressure-bearing component 100 and the clamping mounting assembly 300 are mounted on the same base 400 or the same foundation. The clamping component 200 is disposed between the pressure-bearing component 100 and the clamping mounting assembly 300. A gap 500 is provided between the clamping component 200 and the pressure-bearing component 100. When the water-blocking assembly 600 is blocking water, it is inserted into the gap 500 and pressed against the pressure-bearing component 100 by the perimeter of the clamping component 200. When not blocking water, the clamping component 200 is released and the water-blocking assembly 600 is removed from the gap 500, so that a channel is formed within the pressure-bearing component 100, the clamping component 200, and the clamping mounting assembly 300, allowing people and vehicles to pass together.

[0034] To better compress the sealing and water-blocking assembly 600, soft pads 210 and 110 with sealing stripes are provided on both the side of the pressing member 200 opposite to the pressure-bearing member 100 and the side of the pressure-bearing member 100 opposite to the pressing member 200. In this way, the pressing member 200 presses the water-blocking assembly 600 onto the soft pad 110 of the sealing stripes of the pressure-bearing member 100 through the soft pad 210 with sealing stripes.

[0035] The compression drive assembly of this embodiment includes an inflatable bladder 710 and an inflator 720. The inflatable bladder 710 is disposed between the compression mounting assembly 300 and the compression member 200, specifically connected to the side of the compression mounting assembly 300 facing the compression member 200 and the side of the compression member 200 facing the compression mounting assembly 300. The inflator 720 is mounted on the compression mounting assembly 300 or the base 400 (in this embodiment, it is mounted on the compression mounting assembly 300), and the inflation nozzle of the inflator 720 is connected to the inflatable bladder 710 to inflate it. The inflatable bladder 710 is provided with a deflation nozzle; opening the deflation nozzle allows air to be released from the inflatable bladder 710, and closing the deflation nozzle allows air to be inflated into the inflatable bladder 710. In addition, to quickly deflate the airbag 710, an automatic return handle 220 with a matching spring is provided on the side of the clamping member 200 facing the clamping mounting assembly 300. The handle 220 passes through the clamping mounting assembly 300 and can move relative to the clamping mounting assembly 300. In this way, when the vent valve is opened, the pressure inside the airbag decreases and the automatic return handle 220 is pushed by the spring, which can drive the clamping member 200 to move towards the clamping mounting assembly 300, compressing the airbag 710 and achieving rapid deflation.

[0036] Example 2

[0037] Referring to Figure 2, the difference between this embodiment and the water-blocking device with a top-pressure sealing structure in Embodiment 1 is that the pressing drive assembly is different. The pressing drive assembly in Embodiment 1 includes several screw pressing mechanisms 800. The driving part 810 of each screw pressing mechanism 800 is mounted on the pressing mounting assembly 300. The screw nut 820 in each screw pressing mechanism 800 is connected to the pressing member 200. The screw 830 of the screw pressing mechanism 800 drives the pressing member 200 to move through the screw nut 820. The water-blocking assembly 600 is pressed against the soft pad 110 of the sealing strip of the pressure bearing member 100 through the soft pad 210 of the sealing strip.

[0038] If the lead screw 830 is very long, the end of the lead screw 830 will be axially mounted on the pressure member 100 away from the drive part 810 of the lead screw clamping mechanism 800, for example, the side of the pressure member 100 will not pass through the water-blocking assembly 600.

[0039] The driving part of the lead screw clamping mechanism 800 is a handwheel and a reduction gearbox or a motor and a reduction gearbox. The handwheel or motor drives the lead screw 830 to rotate through the reduction gearbox. The rest is the same as in Embodiment 1.

[0040] Example 3

[0041] Referring to Figure 3, the difference between this embodiment and the water-blocking device with a top-pressure sealing structure in Embodiment 1 is that: the pressing drive assembly includes several hydraulic jacks 900, the hydraulic cylinders 910 of the hydraulic jacks 900 are mounted on the pressing mounting assembly 300, the push rods 920 of the hydraulic jacks 900 are connected to the pressing member 200, and the pressing member 200 is driven to move through the soft pads 210 of the sealing strips to press the water-blocking assembly 600 onto the soft pads 110 of the sealing strips of the pressure-bearing member 100. The rest is the same as in Embodiment 1.

[0042] Example 4

[0043] Referring to Figure 4, the water-blocking component 600 in this embodiment consists of several water-blocking plates 610, and the rest is the same as in embodiment 1, 2 or 3.

[0044] Example 5

[0045] Referring to Figure 5, the water-blocking component 600 in this embodiment is a water-blocking roller shutter 620, wherein the roller shutter shaft 621 of the water-blocking roller shutter 620 is disposed on the top of the pressure-bearing member 100 or the pressing mounting assembly 300, and the roller shutter shaft 621 is used for the raising and lowering of the water-blocking roller shutter 620. The roller shutter shaft 621 of the water-blocking roller shutter 620 can be a manual roller shutter shaft or an electric roller shutter shaft.
