Description

Technical Field

[0001] This utility model relates to the technical field of flood control and water barrier devices, and in particular to a water barrier device for flood control at building entrances and exits. Background Technology

[0002] Due to the impact of global climate change, extreme rainfall is increasing, and urban flooding is becoming more prominent. Building entrances and exits are key channels for flood intrusion. Once flooded, they can easily cause property damage, equipment damage, and even threaten the safety of people. Especially in low-lying areas prone to water accumulation, such as underground garages and subway stations, traditional flood control measures (such as sandbags and temporary barriers) are difficult to effectively block floods at high water levels. On the one hand, the joints of traditional water-blocking devices have poor sealing, which can easily lead to leakage and deformation at high water levels, and the bottom sealing strip is difficult to adapt to uneven ground. On the other hand, some devices are made of materials with insufficient strength and cannot withstand the water pressure load at high water levels, posing a risk of breakage and collapse.

[0008] Preferably, the lower end of the stainless steel water-blocking frame is inserted into the bottom connecting frame. The stainless steel water-blocking frame is snapped into the front and rear ends of the stainless steel water-blocking frame by two limiting plates. The stainless steel water-blocking frame is detachably connected to the bottom connecting frame by two limiting plates and two fastening bolts, respectively. The ends of the two fastening bolts that are close to each other are respectively located in the threaded connection of the two bolt holes.

A diagonal brace is fixedly connected to the middle part of the upper end and the lower part of the right end of the two side fixing brackets respectively. A side fixing bolt is threadedly connected to the upper right part of the two side fixing brackets.

[0013] By adopting the above technical solution: the side fixing bracket is connected to the bottom connecting frame through the main water baffle slot, the horizontal connecting rod and the diagonal brace enhance the overall rigidity, the side fixing bolts ensure that the installation is firm, and the side of the device is reinforced to prevent lateral tilting and deformation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this utility model, the stainless steel water-blocking frame serves as the main body, which is sturdy, durable, and corrosion-resistant. The V-shaped diversion blocks disperse the impact force of floodwater laterally, reducing the frontal pressure on the water-blocking device and minimizing debris accumulation. The reinforcing ribs and transverse reinforcing plates enhance the structural strength, effectively resisting high water pressure and preventing deformation and breakage. The sealed and fitted panel improves the overall sealing performance and reduces the risk of leakage. The limiting plate and bolt holes work together to secure the bolts, achieving a stable and detachable connection with the bottom connecting frame, facilitating installation, disassembly, and maintenance. The rectangular array of V-shaped diversion blocks ensures uniform flow guidance. The combined effect of all components significantly enhances the practicality and reliability of the water-blocking device.

[0022] 2. In this utility model, two mirror-distributed side-fixed brackets are engaged with the bottom connecting frame using the main water-blocking plate slot. The left end face abuts against the sealing panel to form a stable lateral support. The transverse connecting rod and the diagonal brace form a triangular structure to evenly distribute the lateral pressure of the flood, avoiding excessive local stress that could cause the device to tilt or be damaged. The side fixing bolts further reinforce the brackets to ensure a tight and secure connection. The coordinated action of all components not only enhances the overall rigidity of the water-blocking device but also optimizes the sealing performance, effectively resisting high water pressure, significantly reducing the risk of device collapse, and ensuring the flood control safety of building entrances and exits.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A flood-prevention water-blocking device for building entrances includes a bottom connecting frame 1, a bottom sealing strip 2 fixedly connected to the lower end of the bottom connecting frame 1, fastening bolts 3 threadedly connected to the middle of the front end and the middle of the rear end of the bottom connecting frame 1, an auxiliary water-blocking structure 4 inserted into the bottom connecting frame 1, and a side reinforcement structure 5 provided at the right end of the auxiliary water-blocking structure 4.

[0033] In this embodiment, the auxiliary water-blocking structure 4 includes a stainless steel water-blocking frame 41. Several V-shaped drainage blocks 42 are fixedly connected to the lower left end of the stainless steel water-blocking frame 41. Limiting plates 43 are fixedly connected to the lower front and lower rear ends of the stainless steel water-blocking frame 41. Several reinforcing ribs 44 are provided on the inner left side of the stainless steel water-blocking frame 41. A transverse reinforcing plate 45 is fixedly connected to the middle of the inner wall of the stainless steel water-blocking frame 41. A sealing and fitting panel 46 is fixedly connected to the right end of the stainless steel water-blocking frame 41. Bolt holes 47 are provided at the lower front and lower rear ends. The lower end of the stainless steel water-blocking frame 41 is inserted into the bottom connecting frame 1. The stainless steel water-blocking frame 41 is connected to the front and rear ends of the stainless steel water-blocking frame 41 by two limiting plates 43. The stainless steel water-blocking frame 41 is detachably connected to the bottom connecting frame 1 by two limiting plates 43 and two fastening bolts 3 respectively. The ends of the two fastening bolts 3 that are close to each other are respectively located in the two bolt holes 47 for movable thread connection. Several V-shaped diversion blocks 42 are distributed in a rectangular array.

[0034] Through the above scheme: the stainless steel water-blocking frame 41, together with the sealing and fitting panel 46, forms an integrated structure, reducing splicing gaps and lowering the risk of leakage. The bottom is inserted into the bottom connecting frame 1, and with the limiting plate 43 and fastening bolts 3, the connection is ensured to be tight and avoid deformation caused by water pressure. The rectangular array of V-shaped diversion blocks 42 disperses the impact force of floodwater laterally, reducing the front pressure on the water-blocking device and reducing the possibility of deformation. The transverse reinforcing plate 45 and the reinforcing rib column 44 enhance the overall structural strength and resist high water pressure. This design does not rely on the traditional bottom sealing strip. Through the tight insertion and snap-fit ​​structure, it adapts to uneven ground and effectively improves the sealing performance and deformation resistance of the water-blocking device.

[0035] In this embodiment, the side reinforcement structure 5 includes two side fixing brackets 51. A transverse connecting rod 52 is fixedly connected to the upper part of the two side fixing brackets 51. A main water baffle slot 53 is opened on the lower left part of the two side fixing brackets 51. A diagonal brace 54 is fixedly connected to the middle of the upper end and the lower right end of the two side fixing brackets 51 respectively. A side fixing bolt 55 is threadedly connected to the upper right part of the two side fixing brackets 51. The two side fixing brackets 51 are distributed in a front-to-back mirror image. The two side fixing brackets 51 are respectively engaged with the right end of the two bottom connecting frames 1 through the two main water baffle slots 53. The left end face of the two side fixing brackets 51 is tightly abutted against the sealing and bonding panel 46.

[0036] Through the above scheme: two side-fixed brackets 51 distributed in a front-to-back mirror shape are connected to the bottom connecting frame 1 by the main water baffle plate slot 53, and the left end face is pressed against the sealing and fitting panel 46 to form a stable lateral support. The transverse connecting rod 52 and the diagonal brace 54 form a triangular stable structure to disperse and transmit the lateral force generated by the water pressure, reduce the single point of force, and the side fixing bolts 55 further tighten the brackets to prevent loosening and displacement. The coordinated action of each component enhances the overall rigidity and stability of the water baffle device, effectively compensates for the risk of breakage and collapse caused by insufficient material strength, and improves the reliability of the device under high water pressure.

[0037] It should be noted that this utility model is a flood-prevention water-blocking device for building entrances and exits. During use, firstly, the bottom sealing strip 2 at the lower end of the bottom connecting frame 1 tightly adheres to the ground, preventing floodwater from seeping in from the bottom. The stainless steel water-blocking frame 41 of the auxiliary water-blocking structure 4 is securely connected to the fastening bolts 3 and the bottom connecting frame 1 via the limiting plate 43. The internal reinforcing ribs 44 and the transverse reinforcing plates 45 enhance structural strength. The sealing and fitting panel 46 improves sealing performance. The V-shaped diversion blocks 42, distributed in a rectangular array, laterally disperse the flood impact force, reducing frontal water pressure. In the reinforcement structure 5, two mirror-distributed side fixing brackets 51 are connected to the bottom connecting frame 1 through the main water baffle slot 53 and abut against the sealing and fitting panel 46. The transverse connecting rod 52 and the diagonal brace 54 form a stable triangular structure. The side fixing bolts 55 are further tightened to effectively resist the lateral pressure of flood. Therefore, through the innovative design and cooperation of multiple components, the problems of poor sealing and weak water pressure resistance of traditional devices are effectively solved. It has the characteristics of convenient installation, strong sealing, stable structure and excellent impact resistance, and can provide reliable flood protection for building entrances and exits.
