Description

Technical Field

[0001] This utility model relates to the field of flood control technology, specifically to a buoyancy- and counterweight-triggered flood control baffle. Background Technology

[0002] With the increase in natural disasters, especially torrential rains, floods have caused enormous losses, making flood prevention particularly important. Flood prevention involves work related to flood forecasting, flood control scheduling, and the operation of flood control projects to prevent and mitigate flood disasters. Flood barriers are commonly used to control accumulated water during flood prevention efforts.

[0003] Existing flood control barriers (such as the one in application number 202123301987.5) utilize support and adjustment devices and auxiliary support devices to block water in various terrain conditions. However, most existing flood control barriers are passive installation structures, requiring manual installation after rainwater levels exceed the warning line. They cannot be installed concealed, nor can they respond promptly to buoyancy or gravity to extend, thus affecting their efficiency and quality in blocking rainwater. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide a buoyancy- and counterweight-triggered flood control barrier to solve the technical problem that most existing flood control barriers are passive, requiring manual installation after rainwater exceeds the warning line, and cannot be installed in a concealed manner. Furthermore, the barrier should respond promptly to buoyancy or gravity to extend, thus affecting the efficiency and quality of the flood control barrier in blocking rainwater.

[0005] According to the technical solution provided in the embodiments of this application, a buoyancy- and counterweight-triggered flood control barrier includes a flood control barrier body, which is installed in an installation groove on the ground by concrete pouring. The flood control baffle body includes a protective plate and a baffle. The baffle is movably fitted into a protective groove on the protective plate, and a lifting mechanism is installed at the bottom of the baffle so that the lifting mechanism moves upward along the protective groove to adjust the water blocking depth of the baffle. The triggering component, located below the water inlet on the side plate at the top of the protective plate, includes a collection pipe, a buoyancy triggering mechanism, and a gravity triggering mechanism. The buoyancy triggering mechanism is installed on the side of the collection pipe for buoyancy triggering activation of the flood control baffle body, while the gravity triggering mechanism is installed at the bottom of the collection pipe for gravity triggering activation of the flood control baffle body.

[0006] Furthermore, the baffle is a hollow rectangular plate, and the nut installed at the bottom center is screwed to the lead screw of the lifting mechanism.

[0007] Furthermore, the lifting mechanism includes a rotation drive, a lead screw, and two guide rods. The two guide rods are correspondingly installed on both sides of the lead screw, and the guide rods are movably installed in the through holes of the baffle. The rotation drive is fixedly connected to the output end of the lead screw, so that the rotation drive drives the baffle connected to the lead screw to move in the vertical direction.

[0008] Furthermore, the buoyancy triggering mechanism includes a buoyancy tube, a buoyancy ball, and a first triggering sensor. The buoyancy tube is connected to the collection tube through two connecting pipes, and the buoyancy ball is installed inside the buoyancy tube. The first triggering sensor is installed on the top of the buoyancy tube so that the buoyancy ball floats up along the buoyancy tube, thereby triggering the first triggering sensor.

[0009] Furthermore, the gravity triggering mechanism includes a linkage rod, an elastic element, and a gravity sensor. The linkage rod is movably installed inside the collection tube, the elastic element is sleeved on the bottom of the linkage rod, and the gravity sensor is installed on the bottom of the linkage rod so that the collected rainwater pushes the linkage rod downward, thereby triggering the gravity sensor to start.

[0010] Furthermore, a filter screen is attached to the water inlet for filtering impurities in the rainwater.

[0011] Furthermore, a limiting plate is provided on the side of the protective plate, and a sealing strip is installed on the side of the limiting plate to prevent rainwater from entering the interior of the protective plate.

[0012] Furthermore, the first trigger sensor and the gravity sensor are pressure sensors, and the first trigger sensor and the gravity sensor are electrically connected to the controller via a connecting line. The controller is electrically connected to the rotation drive via a connecting line, thereby controlling the rotation drive to start.

[0013] In summary, the beneficial effects of this application are as follows: 1. By installing a triggering component on the flood control barrier, the buoyancy triggering mechanism and gravity triggering mechanism on the triggering component will trigger the first triggering sensor after rainwater enters the collection pipe, and the linkage rod will touch the gravity sensor. This will enable the dual sensing of buoyancy and gravity to detect the amount of rainwater during the flood season, thereby quickly activating the flood control barrier. This replaces the original manual installation of flood control barriers, which is inefficient, prevents rainwater from seeping into the interior of buildings, and improves the practicality of the flood control barrier. Second, by setting the flood control baffle into a concealed structure, the baffle is retracted into the protective groove of the protective plate when not in use. When the buoyancy trigger mechanism and the gravity trigger mechanism trigger the pressure sensor, the rotation drive component on the lifting mechanism is driven to move the baffle up, so that the baffle moves up to block rainwater and carry out flood control and flood fighting, thereby improving the flood control quality of the flood control baffle.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Buoyancy- and counterweight-triggered flood control barriers, such as Figure 1 and Figure 2As shown, the flood control barrier body 100 is installed in the installation groove on the ground by concrete pouring, so that the flood control barrier body 100 has a hidden structure. When not needed, the barrier 120 is stored in the protective groove 111 on the protective plate 110. When in use, the barrier 120 moves up along the protective groove 111 to block rainwater.

[0019] like Figure 1 and Figure 2 As shown, the flood control baffle body 100 includes a protective plate 110 and a baffle 120. The baffle 120 is a rectangular structure plate, while the protective plate 110 has a U-shaped structure. The baffle 120 is movably fitted into the protective groove 111 on the protective plate 110. A lifting mechanism 130 is installed at the bottom of the baffle 120 so that the rotation drive component 131 on the lifting mechanism 130 is started under the control of the controller, thereby driving the fixedly connected screw 132 to rotate, so that the screw 132 drives the screwed baffle 120 to move up and down along the vertical direction of the two guide rods 133, thereby adjusting the water blocking depth of the baffle 120.

[0020] like Figure 2 and Figure 3As shown, the trigger assembly 140 is installed at the bottom of the water inlet of the top side plate 114 of the protective plate 110. The trigger assembly 140 includes a collection pipe 141, a buoyancy trigger mechanism 142, and a gravity trigger mechanism 143. The buoyancy trigger mechanism 142 is installed on the side of the collection pipe 141 and includes a buoyancy tube 1421, a buoyancy ball 1422, and a first trigger sensor 1423. The buoyancy tube 1421 is connected to the collection pipe 141 through two connecting pipes. The buoyancy ball 1422 is installed inside the buoyancy tube 1421, and the first trigger sensor 1423 is installed at the top of the buoyancy tube 1421 so that the buoyancy ball floats up along the buoyancy tube 1421, thereby triggering the first trigger sensor 1423 to activate the buoyancy of the flood control baffle body 100. The gravity trigger mechanism 143 is installed at the bottom of the collection tube 141. The gravity trigger mechanism 143 includes a linkage rod 1431, an elastic element 1432, and a gravity sensor. The device 1433 and the linkage rod 1431 are movably installed inside the collection pipe 141, while the elastic element 1432 is sleeved on the bottom of the linkage rod 1431, and the gravity sensor 1433 is installed on the bottom of the linkage rod 1431. The collected rainwater pushes the linkage rod 1431 downward, thereby triggering the gravity sensor 1433 to start. This is used for the gravity-triggered start of the flood control baffle body 100. The first trigger sensor 1423 and the gravity sensor 1433 are pressure sensors, and the first trigger sensor 1423 and the gravity sensor 1433 are electrically connected to the controller through a connecting wire. The controller is electrically connected to the rotation drive 131 through a connecting wire, thereby controlling the rotation drive 131 to start and achieve dual sensing of buoyancy and gravity. This allows the flood control baffle to quickly start and respond according to the rainfall during the flood season, replacing the original low efficiency problem of manual installation of flood control baffles, preventing rainwater from seeping into the interior of buildings, and improving the practicality of flood control baffles.

[0021] like Figure 4 As shown, the lifting mechanism 130 includes a rotation drive 131, a lead screw 132, and two guide rods 133. The two guide rods 133 are correspondingly installed on both sides of the lead screw 132, and the guide rods 133 are movably installed in the through holes of the baffle 120. The rotation drive 131 is fixedly connected to the output end of the lead screw 132, so that the rotation drive 131 drives the lead screw 132 to rotate, so that the baffle 120 screwed to the lead screw 132 moves in the vertical direction, so that the baffle 120 moves linearly along the guide rods 133, adjusting the water blocking height of the baffle 120, so that the water blocking height of the baffle 120 can be adjusted according to the rainwater volume requirements, thereby improving the practicality of the flood control baffle.

[0022] like Figure 1 and Figure 2 As shown, a filter screen 150 is snapped into the water inlet. The filter holes at the upper end of the filter screen 150 are larger than the diameter of the filter holes at the bottom, thereby filtering the rainwater entering the collection pipe 141 and preventing impurities in the rainwater from entering the collection pipe 141.

[0023] like Figure 1 and Figure 2 As shown, two corresponding limiting plates 112 are provided at the opening of the protective plate 110, and a sealing strip 113 is installed on the side of the limiting plate 112. The sealing strip 113 is made of elastic rubber so that the sealing strip 113 prevents rainwater from entering the protective groove 111 on the protective plate 110.

[0024] The working principle of this buoyancy- and counterweight-triggered flood control barrier is as follows: In the process of flood control barriers blocking rainwater, traditional flood control barriers are installed manually after visual inspection, which cannot quickly respond to the rainfall. By installing a concealed structure on the building ground, the protective plate 110 on the barrier is installed on the building ground through concrete pouring, and the barrier 120 is movably installed in the protective groove 111 on the protective plate 110. Rainwater enters the collection pipe 141 from the inlet, and the weight of the collected rainwater pushes the linkage rod 1431 downwards. This causes the linkage rod 1431 to compress the elastic element 1432 metal spring, so that the linkage rod 1431 abuts against the gravity sensor 1433 at the bottom during its downward movement, allowing the gravity sensor 1433 to sense the weight of the rainwater. This triggers the rotation drive 131 of the lifting mechanism 130 connected to the electric system to start. At the same time, the buoyancy trigger mechanism 142 on the trigger assembly 140 enters the buoyancy tube 1421 through the connecting pipe connected to the collection pipe 141. This causes the rainwater to move the buoyancy ball 1422 upward along the buoyancy tube 1421 and then come into contact with the first trigger sensor 1423. The pressure sensor on the first trigger sensor 1423 transmits the sensed pressure signal to the controller, which then controls the rotation drive 131 connected to the electric system to start. The trigger assembly 140 is equipped with both buoyancy and gravity sensors to sense the amount of rainfall during the flood season, thereby quickly activating the flood control barrier. This replaces the original manual installation of the flood control barrier, which was inefficient, and prevents rainwater from seeping into the interior of buildings, thus improving the practicality of the flood control barrier. The flood control baffle is designed as a hidden structure so that when the baffle 120 is not in use, it is retracted into the protective groove 111 of the protective plate 110. When the buoyancy triggering mechanism 142 and the gravity triggering mechanism 143 trigger the pressure sensor, the rotation drive component 131 on the lifting mechanism 130 drives the fixedly connected screw 132 to rotate, thereby driving the screwed baffle 120 to move upward, so that the baffle 120 moves upward to block rainwater and carry out flood control and flood prevention, thereby improving the flood control quality of the flood control baffle.

[0025] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
