[0001] The utility model relates to the technical field of flood-proof structures, in particular to an underground garage flood-proof structure. Background Art
[0002] In recent years, during the seasons of frequent heavy rainstorms, underground garages in some communities are always flooded by rainwater, causing damage to a large number of vehicles or important items, and causing huge economic losses to residents. In order to prevent such natural disasters caused by heavy rains, some communities will arrange staff to set up water retaining boards on the ramps of underground garages when the rain is heavier, and pile up flood control sandbags near the water retaining boards to prevent rainwater from pouring into the underground garages. However, this method of relying on manual deployment of flood control facilities is not only slow to respond, but also not convenient to operate, which ultimately leads to poor flood control effects in underground garages. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the utility model provides an underground garage flood prevention structure, which not only responds quickly but also is relatively convenient to operate.
[0004] The utility model adopts the following technical solutions.

[0006] Furthermore, the locking assembly includes a locking tongue slidably connected to the base in a horizontal direction, and a second elastic member is connected between the locking tongue and the base. The second elastic member enables the locking tongue to maintain a tendency to approach the water baffle, and a lock hole that fits with the locking tongue is opened on the side wall of the water baffle.
[0007] Furthermore, a water accumulation cavity is provided at the lower position of the ramp, and an overflow channel is connected between the bottom end of the water accumulation cavity and the drainage groove;

[0027] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.
[0028] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.
[0029] As shown in the attached drawings, an underground garage flood prevention structure comprises a ramp 1, a drainage ditch 11 is provided at a high position of the ramp 1, the drainage ditch 11 is covered with a permeable board 2, a plurality of permeable holes 21 are evenly provided on the permeable board 2, a bottom end of the permeable board 2 close to the lower end of the ramp 1 is integrally connected with a water retaining plate 3, a base 4 slidably connected to the water retaining plate 3 is buried on the ramp 1, a first elastic member 5 is connected between the water retaining plate 3 and the base 4, the first elastic member 5 enables the water retaining plate 3 to maintain a tendency to move upward, a locking assembly and a trigger assembly are provided on the base 4, the locking assembly can confine the water retaining plate 3 within the base 4, and the trigger assembly can enable the locking assembly to release the restriction on the water retaining plate 3.
[0030] When the rain is light, the locking assembly restricts the water baffle 3 in the base 4, and the water-permeable board 2 covers the top of the drainage trough 11, so that the rainwater on the ramp 1 flows into the drainage trough 11 through the water-permeable holes 21 of the water-permeable board 2. When the rain increases, the trigger assembly is activated, so that the locking assembly releases the restriction on the water baffle 3, and under the action of the first elastic member 5, the water baffle 3 rises from the ramp 1. In this way, on the one hand, it can prevent rainwater from flowing into the underground garage along the ramp 1; on the other hand, the raised water baffle 3 also lifts the water-permeable board 2, so that rainwater can directly enter the drainage trough 11, thereby increasing the drainage volume of the drainage trough 11. After the rain stops, the staff can press the water baffle 3 back into the base 4.
[0031] In this embodiment, the first elastic member 5 is a gas spring.
[0032] Preferably, the locking assembly includes a locking tongue 61 slidably connected to the base 4 in a horizontal direction, and a second elastic member 62 is connected between the locking tongue 61 and the base 4. The second elastic member 62 keeps the locking tongue 61 close to the water baffle 3, and a locking hole 31 that fits with the locking tongue 61 is opened on the side wall of the water baffle 3.
[0033] When the locking assembly restricts the water baffle plate 3 in the base 4 , the locking tongue 61 is inserted into the locking hole 31 .
[0034] Preferably, a water accumulation chamber 12 is provided at a lower position of the ramp 1, and an overflow channel 13 is connected between the bottom end of the water accumulation chamber 12 and the drainage groove 11;
[0035] The trigger assembly includes a transmission plate 71 slidably connected to the base 4 in the vertical direction. The bottom end of the transmission plate 71 extends into the water accumulation chamber 12 and is integrally connected to a float 72. An inclined portion 711 is formed at the top of the transmission plate 71, and a transmission pin 611 abutting against the inclined portion 711 is provided on the lock tongue 61.
[0036] Specifically, when the rain increases, part of the rainwater will overflow the water-permeable hole 21 and flow into the water-collecting chamber 12. Once the water inflow of the water-collecting chamber 12 exceeds the water discharge of the overflow channel 13, the water level in the water-collecting chamber 12 will gradually rise, thereby driving the float 72 to float up. Under the cooperation of the inclined portion 711 and the transmission pin 611, the float 72 will push the lock tongue 61 out of the lock hole 31, thereby releasing the restriction on the water retaining plate 3.
[0037] Preferably, the lock tongue 61 is provided with a shift block 612, and the top of the base 4 is provided with an escape hole 41 for the shift block 612 to pass through. When the trigger assembly fails, or when it is not raining, the staff can drive the lock tongue 61 to exit the lock hole 31 through the shift block 612, so that the water baffle 3 rises.
[0038] Preferably, in order to prevent sand and gravel from flowing into the municipal water pipe through the drainage trough 11 , a filter plate 8 is overlapped in the drainage trough 11 .
[0039] Preferably, in order to prevent the filter plate 8 from being blocked by sand and gravel, the filter plate 8 is tilted, and a receiving cavity is provided at a position close to the low end of the filter plate 8 on the ramp 1, and a collection box 9 is slidably connected in the receiving cavity. The side wall of the collection box 9 is provided with a collection hole 91 aligned with the low end of the filter plate 8, and the bottom end of the collection box 9 is provided with a diversion hole 92, which is connected to the drainage trough 11 through a diversion channel 14. When rainwater flows through the filter plate 8, the sand and gravel in the rainwater are intercepted by the filter plate 8 and slide into the collection box 9 along the slope of the filter plate 8. When the sand and gravel accumulated in the collection box 9 reaches a certain amount, the staff can take the collection box 9 out of the receiving cavity for cleaning.
[0040] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
