Description

Technical Field

[0001] This invention relates to the field of urban flood control technology, and in particular to an adaptive water-blocking device for the entrance and exit of an underground parking lot. Background Technology

[0002] In recent years, extreme weather events have become increasingly frequent, with incidents of heavy rain causing flooding in underground parking lots and resulting in significant losses occurring from time to time. Property management companies often rely on manual flood control methods, which are not only slow to respond but also potentially endanger property management personnel. This device mainly consists of a water turbine, a transmission system, and a telescopic flood barrier. During flooding, the system automatically raises the flood barrier above the water surface based on the water level, effectively blocking the water. As the flood recedes, the adaptive system lowers the flood barrier to an appropriate height until the floodwaters recede completely, at which point the barrier is fully lowered. This invention utilizes a mechanical structure to perform all the aforementioned functions, requiring no manual intervention or external energy drive, resulting in a reliable structure and excellent performance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an adaptive water barrier device for the entrance and exit of an underground parking lot, which is free from personnel on duty, has a fast response and a reliable structure, and is mainly used to prevent floods from flowing back into the underground parking lot and causing safety hazards and economic losses.

[0004] The technical solution adopted by this invention to solve its technical problem is: This invention provides an adaptive water-blocking device for the entrance and exit of an underground parking lot, comprising: a power unit, a transmission mechanism, and a telescopic baffle; wherein: The retractable barrier is installed below the ground level of the garage ramp; The power unit includes a water turbine installed below the drainage ditch, a water turbine drive shaft, a main drive bevel gear, a reduction transmission gear, and a reduction flywheel device; the water flow drives the water turbine, and the power is transmitted to the main drive bevel gear through the water turbine drive shaft. The main drive bevel gear meshes with the reduction transmission gear and transmits the power to the reduction flywheel device. The transmission mechanism includes a baffle float system, a baffle lifting conversion device, a power switch, an upward power shaft, a downward reduction shaft, a crank device, a transmission rod, and a transmission reduction gear; the baffle float system is located below the top of the telescopic baffle and is connected to the baffle lifting conversion device; The power switch is connected to the crank assembly, which is also connected to the main power bevel gear and the transmission rod. The transmission rod meshes with the transmission reduction gear, which transmits power to the rising power shaft. The baffle lifting conversion device is connected to the rising power shaft to provide upward power for the telescopic baffle. The baffle lifting conversion device is also connected to the descending reduction shaft. Under the action of gravity, the telescopic baffle is slowly lowered by the baffle lifting conversion device under the action of the descending reduction shaft.

[0005] Furthermore, the speed reduction flywheel device of the present invention includes a speed reduction ratchet; the speed reduction transmission gear includes a speed reduction transmission bearing, a speed reduction bearing surface, a speed reduction pawl spring, and a speed reduction pawl; wherein: The reduction transmission bearing drives the reduction bearing surface to rotate; when the rotation speed of the reduction bearing surface is higher than that of the reduction flywheel device, the reduction pawl extends outward under the action of the reduction pawl spring and engages with the reduction ratchet, driving the reduction flywheel device to rotate; the rotation of the reduction flywheel device converts kinetic energy into potential energy and increases the speed, making the rotation speed of the reduction flywheel device higher than that of the reduction bearing surface, so the reduction pawl cannot engage with the reduction ratchet, and they rotate freely relative to each other.

[0006] Furthermore, the power switch of the present invention includes a power switch float, a power switch float connecting rod, and a curved wedge; the crank device includes a crank and a power transmission bevel gear; the transmission rod includes a power transmission gear and a power transmission gear driven gear; the transmission reduction gear includes a transmission reduction gear driven gear; wherein: When the water level in the drainage ditch rises above the power switch, the float of the power switch moves upward under the action of buoyancy, driving the curved wedge to rotate through the float connecting rod. After the curved wedge rotates, it lifts the crank, causing the power transmission bevel gear to mesh with both the driving bevel gear and the power transmission gear simultaneously, completing the power transmission. The meshing of the power transmission gear transmits power to the transmission rod through the driven gear of the power transmission gear. The transmission rod meshes with the transmission reduction gear, transmitting power to the rising power shaft through the driven gear of the transmission reduction gear.

[0007] Furthermore, the baffle float system of the present invention includes a baffle float shaft, a baffle float, an upper trigger pin, and a lower trigger pin; wherein: When the water level rises, the baffle float will first trigger the lower trigger pin, which locks the descent of the telescopic baffle. As the water level continues to rise, the baffle float will trigger the upper trigger pin, which will initiate the descent of the telescopic baffle. When the water level drops, the baffle float will descend until the upper trigger pin is released, at which point the descent of the telescopic baffle will stop. If the water level continues to drop, the baffle float will release the lower trigger pin, initiating the descent of the telescopic baffle.

[0008] Furthermore, the baffle float system of the present invention also includes an upper trigger transmission rod, an upper trigger transmission rod rotating shaft, and an upper trigger connecting rod; the baffle lifting and lowering conversion device includes an ascending helical gear, an auxiliary gear rod linkage rod, an auxiliary gear rod, and an auxiliary gear rod linkage rod short column; wherein: After the baffle float triggers the upper trigger pin, the upper trigger linkage is pushed, causing the upper trigger transmission rod to rotate with the upper trigger transmission rod shaft as the center; the auxiliary gear linkage short column is pulled to the upper left under the limit of the upper trigger linkage pre-made groove, and the auxiliary gear rod is pulled to the upper left through the auxiliary gear linkage rod, finally causing the rising helical gear to mesh with the rising power shaft, providing the rising power for the telescopic baffle.

[0009] Furthermore, the baffle float system of the present invention also includes an upper trigger link spring, an upper trigger link baffle, and... After the baffle float releases the upper trigger pin, the upper trigger linkage spring pulls the upper trigger linkage baffle back to its original position; the upper trigger linkage is pushed, causing the upper trigger transmission rod to rotate with the upper trigger transmission rod shaft as the center; the auxiliary gear linkage short column is pushed to the lower right under the limit of the upper trigger linkage pre-made groove, and the auxiliary gear rod is pushed to the lower right through the auxiliary gear linkage rod; finally, the rising helical gear disengages from the rising power shaft, causing the telescopic baffle to lose its rising power and stop rising.

[0010] Furthermore, the baffle float system of the present invention also includes a descending locking pawl, a pawl linkage triggering short column, and a descending triggering link; The lower trigger pin is triggered by the baffle float, which causes the lower trigger link to drive the descent locking pawl. The pawl linkage trigger pin is limited by the pre-drilled hole on the lower trigger link.

[0011] Furthermore, the baffle lifting and lowering conversion device of the present invention further includes a descending helical gear and a descending gear post-gear; wherein: When the lower trigger pin is triggered by the baffle float, the descent locking pawl engages with the attached teeth of the descent gear column, causing the descent helical gear to rotate counterclockwise, restricting descent and allowing only the ascent to be completed. When the lower trigger pin is released by the baffle float, the descent locking pawl disengages from the attached teeth of the descent gear column, allowing both ascent and descent to proceed without restriction. However, under the weight of the telescopic baffle itself, the descent helical gear descends slowly under the action of the descent deceleration shaft.

[0012] Furthermore, the baffle lifting and conversion device of the present invention also includes a descending helical gear column, an ascending helical gear, an ascending helical gear column, an ascending gear column auxiliary gear set, an upper structural plate, a lower structural plate, an inclined guide plate, and an auxiliary gear rod; The baffle float triggers the upper trigger pin, pulling the auxiliary gear rod upwards and to the left along the inclined guide plate. The bevel gear at the tail of the auxiliary gear rod meshes with the rising power shaft, which provides power for its rotation. As the auxiliary gear rod is pulled to the upper left, a portion of its threads meshes with the auxiliary gear set of the rising gear column, causing the auxiliary gear set to rotate and pulling the rising helical gear to the right until it meshes with the rising power shaft. After the rising helical gear is pulled to the right and meshes with the rising power shaft, the rising power shaft provides power to raise the telescopic baffle. When the baffle float releases the upper trigger pin, the auxiliary gear rod is pushed downwards and to the right, and the rising helical gear moves upwards under the action of the auxiliary gear set of the rising gear column.

[0013] The beneficial effects of this invention are: (1) This invention requires no additional power source, is environmentally friendly and energy-saving; it requires no manual operation, thus reducing operating costs; (2) The present invention can automatically adjust the height of the water baffle according to the water accumulation status, so as to ensure the normal use of the underground garage when there is a small amount of water accumulation (less than 3cm); (3) The present invention adapts the baffle height according to the water level, has a fast response speed, and restores the underground garage access function immediately after the water recedes without additional operation; (4) The present invention adopts a mechanical structure, which is reliable and requires no additional maintenance.

[0014] In summary, this invention utilizes a water turbine-driven mechanical system to automatically adapt to the severity of flooding and effectively block water. During flooding, the invention automatically raises the flood barrier above the water level to block the water. As the flood recedes, the adaptive system lowers the barrier to a suitable height until the floodwaters recede completely, at which point the barrier is fully lowered back down. This solves the problems of requiring dedicated personnel to monitor flood control at underground parking garage entrances, and the complex, slow-response, and high-maintenance requirements of the flood barrier devices. It achieves the effect of requiring no manual intervention, no external energy drive, reliable structure, and excellent performance. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] The purpose of this invention is to provide an adaptive water-blocking device for the entrance and exit of an underground parking lot that requires no personnel on-site, has a fast response time, and a reliable structure. It is mainly used to prevent floodwater from flowing back into the underground parking lot, thus avoiding safety hazards and economic losses.

[0018] This invention mainly consists of three parts: a power unit, a transmission unit, and a telescopic baffle, as shown in the attached diagram. Figure 1 As shown.

[0019] When it rains, rainwater collects and flows into the drainage ditch. After being filtered by the ditch cover, it enters the drainage ditch. The drainage ditch collects rainwater and flows into the drainage channel, from where it is discharged into the municipal pipe network. At this time, the water flow drives the 21-water turbine, which provides power to the entire device.

[0020] It should be noted that, to prevent the turbine from idling and damaging the system at low water levels, the 25-reduction flywheel device provides load to the 21-turbine when it is unloaded. Simultaneously, the 25-reduction flywheel device also serves to reduce the speed of the 23-drive power bevel gear.

[0021] 25- The working principle of the speed reduction flywheel device is as follows.

[0022] The water flow drives the 21-water turbine, which transmits power to the 23-driving bevel gear via the 22-water turbine drive shaft. The 231-driving bevel gear on the 23-driving bevel gear meshes with the 24-reduction gear, driving the 241-reduction bearing to transmit power to the 25-reduction flywheel device. (Example...) Figure 3 As shown. The cross-section of the 25-reduction flywheel device is a ratchet hub structure, as shown. Figure 5As shown. The 25-reduction flywheel device is a solid steel flywheel with a certain mass, and the flywheel includes a 251-reduction ratchet. Correspondingly, the 241-reduction transmission bearing drives the 242-reduction bearing surface to rotate. When the rotational speed of the 242-reduction bearing surface is higher than that of the 25-reduction flywheel device, they rotate relatively counterclockwise (by a certain speed). Figure 5 (For reference system) Pad 244, under the action of the spring in Pad 243, extends outward and engages with ratchet 251, driving flywheel 25 to rotate. The rotation of flywheel 25 converts kinetic energy into potential energy, increasing its own speed during this process, making its rotational speed higher than that of bearing surface 242. At this point, they rotate clockwise, and pad 244 can no longer engage with ratchet 251, allowing them to rotate freely relative to each other. Through the aforementioned process, the load and deceleration requirements are met.

[0023] If rainfall continues to increase and the water level in the drainage ditch rises above the 33-power switch, the 331-power switch float will move upwards under the influence of buoyancy, which in turn drives the 333-curved wedge to rotate via the 332-power switch float connecting rod. The 333-curved wedge (structure as follows) Figure 4 (As shown) After rotation, crank 362 is lifted, causing bevel gear 364 to mesh simultaneously with drive bevel gear 23 and drive gear 371, completing power transmission. Drive gear 371, through its engagement with the driven wheel of drive gear 372, transmits power to transmission rod 37. Figure 3 As shown. 37-The transmission rod meshes with 38-The transmission reduction gear, and through 381-The driven gear of the transmission reduction gear, power is transmitted to 34-The lifting power shaft, as follows. Figure 6 As shown.

[0024] 31-The baffle float system is positioned approximately 3cm below the top of 1-The telescopic baffle (measured from the top of 31-The baffle float system). Figure 2 As shown. The 31-baffle float system consists of 311-baffle float shaft, 312-baffle float, 3137-upper trigger pin, and 3147-lower trigger pin, as follows. Figure 14As shown. When the water level rises, the 312-baffle float will first trigger the 3147-lower trigger pin. The 3147-lower trigger pin will lock the descent of the 1-telescopic baffle. As the water level continues to rise, the 312-baffle float will trigger the 3137-upper trigger pin, which will initiate the ascent of the 1-telescopic baffle. It is important to note that the design length of the 312-baffle float ensures that the 3147-lower trigger pin is triggered simultaneously with the 3137-upper trigger pin. After the 3137-upper trigger pin initiates the ascent of the 1-telescopic baffle, the 31-baffle float system will rise along with the 1-telescopic baffle, meaning the water level relative to the 31-baffle float system will drop. The drop in water level causes the 312-baffle float to descend, stopping the ascent of the 1-telescopic baffle when the 3137-upper trigger pin is released. If the water level continues to drop, the release of the 312-baffle float and the lowering of the 3147-trigger pin will initiate the descent of the 1-telescopic baffle. Similarly, as the water level repeatedly rises and falls, this mechanical action will ensure that the 1-telescopic baffle remains 3cm above the water surface.

[0025] This section will first describe the system operation of the 3137-up trigger pin linkage.

[0026] After the 312-baffle float triggers the 3137-upper trigger pin, the 3134-upper trigger linkage is pushed, causing the 3131-upper trigger transmission rod to rotate around the 3132-upper trigger transmission rod shaft. The 3244-auxiliary gear rod linkage short column, limited by the pre-made groove of the upper trigger linkage, is pulled upwards and to the left, causing the 3242-auxiliary gear rod to be pulled upwards and to the left via the 3243-auxiliary gear rod linkage. Ultimately, this causes the 3221-rising helical gear to mesh with the 34-rising power shaft, providing upward power to the 1-telescopic baffle, causing it to rise.

[0027] After the 312-baffle float releases the 3137-upper trigger pin, the 3136-upper trigger linkage spring pulls the 3135-upper trigger linkage baffle back to its original position. The 3134-upper trigger linkage is pushed, causing the 3131-upper trigger transmission rod to rotate around the 3132-upper trigger transmission rod shaft. The 3244-auxiliary gear rod linkage short column, limited by the pre-groove of the upper trigger linkage, is pushed downwards and to the right, causing the 3242-auxiliary gear rod to be pushed downwards and to the right via the 3243-auxiliary gear rod linkage. Finally, the 3221-rising helical gear disengages from the 34-rising power shaft, causing the 1-telescopic baffle to lose its upward power and stop rising.

[0028] The structure used for linkage of the upper trigger pin in 3137 is as follows: Figure 15 As shown.

[0029] This section will continue to describe the system actions of the 3147-lower trigger pin linkage.

[0030] The system operation of the 3147-lower trigger pin linkage is similar to that of the 3137-upper trigger pin linkage. The 312-baffle float triggers the 3147-lower trigger pin, causing the 3144-lower trigger linkage to move the 3141-descending locking pawl. This process is mainly accomplished by the pre-drilled hole on the 3144-lower trigger linkage, which limits the movement of the 3143-pawl linkage trigger pin.

[0031] When the 312-baffle float triggers the 3147-lower trigger pin, the 3141-descending locking pawl engages with the 3213-descending gear post teeth. The 3211-descending helical gear can only rotate counterclockwise, restricting descent; only ascending motion can be completed. When the 312-baffle float releases the 3147-lower trigger pin, the 3141-descending locking pawl disengages from the 3213-descending gear post teeth. Ascending and descending motions are unrestricted, but under the weight of the 1-telescopic baffle itself, the 3211-descending helical gear descends slowly under the action of the 35-descending reduction shaft.

[0032] The structure used for the linkage of the 3147-lower trigger pin is as follows: Figure 12 , Figure 13 As shown.

[0033] Finally, the implementation of the rising and falling motion of this invention will be explained.

[0034] 32-The baffle lifting and conversion device consists of 3211-descending helical gear, 3212-descending helical gear post, 3213-descending gear post auxiliary gear, 3221-ascending helical gear, 3222-ascending helical gear post, 3223-ascending gear post auxiliary gear assembly, 3231-upper structural plate, 3232-lower structural plate, 3241-inclined guide plate, and 3242-auxiliary gear rod, as follows. Figure 7 As shown.

[0035] When the 312-baffle float neither triggers the 3137-upper trigger pin nor the 3147-lower trigger pin, the 32-baffle lifting and lowering conversion device is in the position. Figure 7 (a) shows the state. It should be noted that at this point, the 3141-descending locking pawl disengages from the 3213-descending gear post teeth, allowing the 3211-descending helical gear to rotate freely. The 3211-descending helical gear meshes with the 35-descending reduction shaft, and descends slowly under the weight of the 1-telescopic baffle itself. Essentially, the 1-telescopic baffle's own weight acts as the driving force for its descent. The 35-descending reduction shaft is a freely rotating shaft; its engagement with the 3211-descending helical gear here provides deceleration, causing the 1-telescopic baffle to descend slowly.

[0036] When the 312-baffle float triggers the 3147-lower trigger pin, the descent action of the 1-telescopic baffle is locked, and only the ascent action can be completed.

[0037] 312-Baffle float triggers 3137-Upper trigger pin, completing the action described above, pulling 3242-Auxiliary gear rod along 3241-Inclined guide plate to the upper left, at this time as Figure 9 As shown, the system status is as follows Figure 7 As shown in (b). It should be noted here that the 3242-auxiliary gear rod... Figure 8 In the middle, from left to right, the designs are: no wire → wired → no wire → conical tooth design. The 3223-ascending gear column with attached gear set is... Figure 8 In the middle, the upper and lower threads are in opposite directions. The 3242-auxiliary gear rod has a bevel gear at the tail that meshes with the 34-rising power shaft, which provides power for rotation. Figure 9 In this state, the 3242-auxiliary gear rod is pulled to the upper left, and a small amount of thread meshes with the 3223-ascending gear column auxiliary gear set, driving the 3223-ascending gear column auxiliary gear set to rotate, pulling the 3221-ascending helical gear to the right until it meshes with the 34-ascending power shaft, as shown. Figure 10 As shown. The 3221-ascending helical gear pulls to the right until it meshes with the 34-ascending power shaft. The 34-ascending power shaft then provides power to raise the 1-telescopic baffle. The operating condition at this time is as follows. Figure 7 As shown in (c). Similarly, when the 312-baffle float releases the 3137-upper trigger pin, the 3242-auxiliary gear rod is pushed to the lower right, and the 3221-ascending helical gear moves upward under the drive of the 3223-ascending gear post auxiliary gear assembly, thus completing the process. Figure 7 During the process of (c) → (b) → (a), the 1-telescopic baffle stops rising.

[0038] Under the action of the aforementioned mechanical device, the 31-baffle float system on the 1-telescopic baffle tracks the water level and completes the adaptive lifting and lowering process to achieve the design purpose.

[0039] The implementation process of the adaptive water-blocking device for underground parking lot entrances and exits according to an embodiment of the present invention is briefly described as follows: (1) The present invention is installed at the entrance and exit of the parking lot; (2) Rainwater drives the water turbine through the drainage channel to provide power for the entire device; (3) After water accumulates, the baffle float linkage mechanism raises the telescopic baffle to prevent rainwater from flowing back into the underground garage. It should be noted that after the telescopic baffle is raised 3cm above the ground, the linkage switch is triggered to turn off the baffle lifting function of the underground garage to avoid safety issues; (4) During the receding of the floodwater, the float linkage mechanism of the baffle causes the baffle to descend synchronously with the floodwater. It should be noted that when the telescopic baffle rises to less than 3cm above the ground, the linkage switch is triggered, activating the lifting function of the underground parking garage and restoring its use. (5) After the water recedes, the telescopic baffle is fully lowered.

[0040] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0041] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
