Description

Technical Field

[0001] The present application relates to the technical field of building waterproofing, and in particular to a flood prevention device for a residential terrace. Background Art

[0002] As an important rest and green space in modern houses, residential terraces have received more and more attention in recent years. Terraces not only increase the sense of space and comfort of the house, but also play an important role in greening and leisure.

[0003] Terraces and indoor spaces are typically separated by glass doors. However, glass doors are generally not very waterproof, and during heavy rain or typhoons, water from the terrace can easily flow through the glass door and back into the room. Traditional partitioning methods, such as placing sandbags and installing flood control boards, not only require pre-installed items at home but are also difficult, time-consuming, and operationally challenging to install in extreme weather, making them ineffective. Utility Model Content

[0004] In order to effectively waterproof the connection between the terrace and the interior, the present application provides a flood prevention device for a residential terrace.

[0005] This application provides a flood prevention device for a residential terrace, which adopts the following technical solution:

[0006] A flood prevention device for a residential terrace includes a positioning frame, a flood prevention baffle that moves up and down on the positioning frame, a driving component that drives the flood prevention baffle to move up and down, and a water accumulation sensor. The two ends of the flood prevention baffle are inserted into the positioning frame, and positioning grooves for the flood prevention baffle to move up and down are provided on the two side walls inside the positioning frame. A storage groove for accommodating the flood prevention baffle is provided at the upper end of the positioning frame. The water accumulation sensor is set on the terrace and connected to the driving component.

[0007] By adopting this technical solution, when water accumulates on the terrace to a certain level, a water sensor triggers a drive assembly, causing the flood control baffle to lower to the ground, effectively preventing water from entering the residence and protecting the home, thus achieving automated flood control. No on-site installation is required, and flood control is automated, resulting in higher efficiency. When the water recedes, the flood control baffle can be stored in a storage trough, maintaining the terrace's normal use and aesthetics.

[0008] Optionally, the drive assembly includes a first drive wheel, a second drive wheel, a first transmission belt, a second transmission belt and a power piece, and the first drive wheel and the second drive wheel are respectively arranged on both sides of the positioning frame; the first drive wheel and the second drive wheel located on the same side are respectively arranged at the upper and lower ends of the positioning frame, and the two are linked by the first transmission belt, and the two first drive wheels are linked by the second transmission belt, and the power piece can drive one of the first drive wheels to rotate; the two ends of the flood control baffle are respectively connected to the two first transmission belts, and are respectively connected to the same side of the two first transmission belts relative to the first drive wheel.

[0009] By adopting the above technical solution, the drive assembly, which combines a first drive wheel, a second drive wheel, a transmission belt, and a power unit, achieves smooth vertical movement of the flood control baffle. The first and second drive wheels are respectively located at the upper and lower ends of the positioning frame and are linked by a transmission belt, enabling synchronous raising and lowering of both ends of the flood control baffle. The power unit operates the entire flood control baffle system by driving one of the first drive wheels, resulting in an ingenious and efficient design.

[0010] Optionally, connecting rods are respectively provided at both ends of the flood control baffle, and a connecting seat is provided on the side of the connecting rod facing the first transmission belt, and the first transmission belt passes through the connecting seat and is connected to the connecting seat.

[0011] By adopting the above technical solution, it is convenient to install and drive the flood control baffle.

[0012] Optionally, the power component includes a motor, a worm wheel and a worm, a control shaft is coaxially fixed on the first drive wheel, the worm wheel is coaxially sleeved on one of the circumferential sides of the control shaft, the worm is rotatably arranged in the positioning frame, the worm is engaged with the worm wheel, the motor is arranged in the positioning frame, and the output end of the motor is connected to the worm.

[0013] By adopting the above technical solution, the power element uses a combination of a motor, worm gear, and worm. The output of the motor drives the worm, which in turn drives the worm gear and control shaft to rotate, thereby driving the first drive wheel. This design utilizes the speed reduction and self-locking characteristics of the worm gear, making power transmission more stable and reliable.

[0014] Optionally, a limit assembly is further included. When the flood baffle is stored in the storage groove, the limit assembly can limit the downward movement of the flood baffle, and the limit assembly is connected to the water accumulation sensor.

[0015] By adopting the above technical solution, the limit assembly is designed to prevent the flood control baffle from accidentally falling when it is stored in the storage groove, thereby enhancing the safety and stability of the flood control device and avoiding safety hazards caused by accidental falling of the flood control baffle.

[0016] Optionally, the limiting assembly includes a cylinder arranged on the positioning frame, and a positioning block connected to the end of the telescopic shaft of the cylinder. The cylinder can drive the positioning block to slide below the connecting rod, or drive the positioning block to slide until it is disengaged from the connecting rod in a horizontal projection.

[0017] Optionally, the positioning block is chamfered toward one end of the connecting rod, and when the positioning block slides below the connecting rod, the upper surface of the positioning block abuts against the lower surface of the connecting rod.

[0018] By adopting this technical solution, the limiter assembly utilizes a combination of a cylinder and a positioning block, with the cylinder's telescopic shaft driving the positioning block's sliding motion. The chamfered design on the positioning block facilitates smooth contact with the connecting rod during sliding, generating resistance and thereby limiting the position of the flood control baffle. This design is simple, practical, and easy to operate and maintain.

[0019] Optionally, a first sealing strip is provided on the side wall of the positioning groove, and the first sealing strip is respectively provided on both sides of the flood control baffle and the two side walls of the positioning groove.

[0020] By adopting the above technical solution, a first sealing strip is provided on the side wall of the positioning groove, which can effectively prevent rainwater or accumulated water from seeping into the gap between the positioning groove and the flood control baffle, thereby improving the sealing performance of the flood control device and enhancing its waterproof effect.

[0021] Optionally, a second sealing strip is provided on the lower surface of the flood control baffle.

[0022] By adopting the above technical solution, when the flood control baffle is lowered and contacts the terrace ground, the second sealing strip can fit tightly to the ground to prevent rainwater or accumulated water from seeping in from the contact surface. This design enhances the waterproof effect of the flood control device and protects the safety inside the house.

[0023] In summary, this application has at least one of the following beneficial effects:

[0024] 1. The water accumulation sensor automatically triggers the drive component to achieve rapid raising and lowering of the flood control baffle, effectively preventing water from accumulating on the terrace from entering the interior of the house;

[0025] 2. The design of the limit assembly and sealing strip further enhances the stability and sealing of the flood control device. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a flood prevention device for a residential terrace. Figure 1 and Figure 2 The flood prevention device includes a positioning frame 1, a flood prevention baffle 2 that moves up and down on the positioning frame 1, a driving component 3 that drives the flood prevention baffle 2 to move up and down, and a water accumulation sensor 4. Among them, the positioning frame 1 is fixed to the wall at the connection between the terrace and the indoor space, the sliding glass door can be set on the side of the positioning frame 1 close to the indoor space, the flood prevention baffle 2 is set on the side of the positioning frame 1 close to the outdoor space, the two ends of the flood prevention baffle 2 are inserted into the positioning frame 1, and the two side walls inside the positioning frame 1 are provided with positioning grooves 11 for the flood prevention baffle 2 to move up and down. The upper end of the positioning frame 1 is provided with a storage groove for accommodating the flood prevention baffle 2. The water accumulation sensor 4 is set on the terrace and has a certain height from the terrace ground; the water accumulation sensor 4 is connected to the driving component 3 by signal.

[0033] Normally, the flood control baffle 2 is stored in the storage slot at the upper end of the positioning frame 1. When extreme weather conditions such as heavy rain occur, causing water to accumulate on the terrace and spread to the water accumulation sensor 4, the water accumulation sensor 4 is triggered, thereby transmitting a signal to the drive component 3. The drive component 3 starts, driving the flood control baffle 2 to descend and contact the ground, thereby forming a retaining wall to effectively block the accumulated water. At the same time, when the water accumulation sensor 4 senses that the water has receded for a certain period of time, it starts the drive component 3 again to raise the baffle. Compared with the temporary installation of flood control boards, this lifting flood control baffle 2 is more convenient and quick to use, and can be automatically started, with better results.

[0034] It should be noted that in order to increase the safety of the use of the flood control baffle 2, voice broadcasting equipment and braking equipment can be added. When the flood control baffle 2 needs to be lowered or raised, the voice broadcasting equipment will first give a voice broadcast prompt; the braking equipment needs to be set in a position that is convenient for control, so that it can be used to control the flood control baffle 2 to stop moving in time when an accident occurs.

[0035] Reference Figure 2 and Figure 3 In this embodiment, a first sealing strip 12 is fixed to the side wall of the positioning groove 11. The sealing strip is preferably provided on both vertical side walls of the positioning groove 11 to ensure sealing between the flood control baffle 2 and the positioning frame 1 when the baffle 2 moves, thereby preventing rainwater from flowing in from the sides. The first sealing strip 12 can be made of TPE material, which has good sealing properties and is not easily aged. At the same time, a second sealing strip 23 can be fixed to the lower surface of the flood control baffle 2. The second sealing strip 23 extends along the length of the flood control baffle 2 and contacts the ground when the baffle moves down to the closed state, thereby enhancing the waterproof effect.

[0036] Reference Figure 3 and Figure 4 The driving assembly 3 includes a first driving wheel 31, a second driving wheel 32, a first transmission belt 33, a second transmission belt 34 and a power piece 35. The first driving wheel 31 and the second driving wheel 32 are respectively arranged on the left and right sides of the positioning frame 1, wherein the first driving wheel 31 is arranged at the upper end of the positioning frame 1, and the second driving wheel 32 is arranged at the lower end of the positioning frame 1. The first driving wheel 31 and the second driving wheel 32 located on the same side are linked by the first transmission belt 33, and the two first driving wheels 31 located at the upper end of the positioning frame 1 are linked by the second transmission belt 34 to ensure the consistency of movement on both sides.

[0037] Specifically, the first drive wheel 31 includes two coaxially connected sprockets, the second drive wheel 32 includes a single sprocket, and both the first transmission belt 33 and the second transmission belt 34 are chains. This allows for stable, synchronous rotation between the first and second drive wheels 31, as well as between the two first drive wheels 31, via the chains. The flood control baffle 2 is connected to the first transmission belt 33 at both ends, and both are connected to the same side of the first transmission belt 33 relative to the first drive wheel 31, allowing both ends of the flood control baffle 2 to be subjected to synchronous upward or downward forces.

[0038] In this embodiment, connecting rods 21 are fixed at both ends of the flood control baffle 2. The connecting rods 21 can be set as rectangular rods. A connecting seat 22 is fixed on the side wall of the connecting rod 21 facing the first transmission belt 33. In this embodiment, the positions of the connecting seats 22 on the two connecting rods 21 correspond to the right side belt bodies of the two first transmission belts 33, so that the right side of the first transmission belt 33 passes through the connecting seat 22 and is fixedly connected to it. When the first transmission belt 33 rotates, it can drive the flood control baffle 2 to move up and down.

[0039] Reference Figure 3 and Figure 4 The power member 35 is disposed within the positioning frame 1 and may be a motor 351. A control shaft is coaxially fixed to one of the first drive wheels 31. The motor 351 is connected to the control shaft via a coupling, thereby enabling rapid control of the rotation of the first drive wheel 31, thereby driving the two first transmission belts 33 to rotate, thereby driving the flood control baffle 2 to move up and down. To improve the stability of the flood control baffle 2, in this embodiment, the power member 35 includes a motor 351, a worm gear 352, and a worm 253. The worm gear 352 is coaxially fixed to the outside of the control shaft, and the worm 253 is rotatably disposed within the positioning frame 1. The worm gear 352 meshes with the worm 253. The motor 351 is fixed within the positioning frame 1, and the output end of the motor 351 is connected to the worm 253. The signal chain between the motor 351 and the water accumulation sensor 4 activates the motor 351. Through the transmission of the worm gear 352 and the worm 253, the first drive wheel 31 can be driven to rotate, thereby driving the first transmission belt 33 to rotate and driving the flood control baffle 2 to move up and down. Ensure the transmission continuity and stability required for the flood control baffle 2 to move up and down.

[0040] Reference Figure 3 and Figure 4 In an optional embodiment, the flood control device further includes a limiter assembly 5. When the flood control baffle 2 is located in the storage slot, the limiter assembly 5 can limit the downward movement of the flood control baffle 2, thereby improving the safety of the flood control baffle 2 and preventing the flood control baffle 2 from failing and falling. The limiter assembly 5 is also connected to the water accumulation sensor 4, which can automatically unlock the limiter assembly 5.

[0041] Specifically, the limiting assembly 5 includes a cylinder 51 and a positioning block 52, which are respectively arranged on the left and right sides of the positioning frame 1. The cylinder 51 is fixed in the positioning frame 1, and the telescopic axis of the cylinder 51 is arranged in the horizontal direction. The positioning block 52 is fixed to the end of the telescopic axis of the cylinder 51. When the telescopic axis of the cylinder 51 is extended, the positioning block 52 slides to the bottom of the flood baffle 2, and the upper surface of the positioning plate abuts against the lower surface of the flood baffle 2, thereby limiting the downward movement of the flood baffle 2; in order to facilitate the positioning plate to slide under the flood baffle, the positioning block 52 has a chamfered upper surface facing the flood baffle 2; when the telescopic axis of the cylinder 51 is retracted, the positioning block 52 slides and disengages from the connecting rod 21 in the horizontal projection, at which time the flood baffle can be moved downward.

[0042] The principle of the flood control device for a residential terrace according to the present embodiment is as follows: When water accumulates on the terrace, the water sensor 4 is triggered. The water sensor 4 first activates the cylinder 51 and moves the positioning block 52 away from the flood control baffle 2. The water sensor 4 then activates the motor 351, driving the flood control baffle 2 downward until it touches the ground, thus providing a water barrier. When the water recedes and the water level remains below the water sensor 4 for a certain period of time, the water sensor 4 sequentially activates the motor 351 and the cylinder 51, moving the flood control baffle 2 upward again and storing it in the storage slot.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
