[0001] The present invention relates to the technical field of drainage and flood prevention, and in particular to a semi-automatic flood prevention device based on a rail transit tunnel system. Background Art

[0002] The location of subway track construction is at a relatively low position. During the construction of subway transportation, in order to improve the drainage effect, a small section of the road will be built into a low-lying state to improve the water diversion effect. The low-lying area will accumulate water when it rains. If the accumulated water is too high, it will affect the safety of subway transportation. Generally, drainage and flood prevention mechanisms will be set up to drain the accumulated water when it rains to ensure the safety of subway travel.

[0013] Beneficial Effects

[0014] The metal rings and metal electrodes according to the various embodiments of the present invention provide a trigger function. When the floating plate rises, the outer slide cylinder is lifted. When the outer slide cylinder rises to the top, the metal ring contacts the metal electrode to turn on the water pump. The water pump operates automatically. When there is a lot of water in the track drainage ditch, it will flow into the circular water pool. The circular water pool automatically drains or manually drains according to the set principle. The circular water pool can be used as a conventional water reservoir to provide water.

[0015] In addition, the water pump can be manually controlled to pump water. The water pump can be manually started to discharge water through the primary one-way valve and the tee from the secondary one-way valve. This can ensure that when one set of water pumps fails, the other set of water pumps can operate normally, and the idle water pump will not reverse the flow of water.

[0016] In addition, the setting of the LED light provides a warning function. When rainwater accumulates, it will enter the water inlet tank and lift the float block through buoyancy. When the float block rises, it will push a group of arc bars to the front side. The arc bars move forward through the slide groove and the guide part, and the metal tube contacts the contact part. The LED light is energized through the contact part, making the LED light light up and displaying color to serve as a warning, which can help subway drivers and patrol personnel identify the water level.

[0017] In addition, after the accumulated water is drained, the float can automatically drop with the water level. The weight of the float itself and the guide structure can push the arc bar away, and then ensure that the float falls naturally. BRIEF DESCRIPTION OF THE DRAWINGS

When the water level reaches yellow or above, it means more than half a meter, and red means 1 meter. Setting two groups of red LED lights 905 can prolong the warning effect, and the danger warning will not be quickly lifted during the water level drop, providing a safety warning effect.

[0039] Specific usage and function of this embodiment: In the present invention, the circular pool 1 is pre-buried at the lowest level at the intersection of the subway lines, the grid 2 is facing the direction of the subway, and the flat floor 3 is aligned with the surrounding ground to complete the preset.

[0040] When it rains, water passes through the grid 2 and is discharged from the drain port 201, and enters the circular pool 1 from the input channel 101, where it is collected and the floating plate 403 is lifted. When the floating plate 403 rises, the outer slide 402 is lifted. When the outer slide 402 rises to the top, the metal ring 404 contacts the metal electrode 5, and the water pump 6 is turned on. The water pump 6 operates automatically to pump out the water in the circular pool 1 and discharge it into the drainage channels on both sides of the subway track, thereby completing automatic drainage.

[0041] When the water stored in the circular pool 1 needs to be used later, it is necessary to preset a manually controlled start-up circuit for the water pump 6, and manually start the water pump 6 to pump water, so as to realize the overall semi-automation of the flood prevention device; the water pump 6 passes the primary one-way valve 601 and the three-way valve 602 and discharges the water from the secondary one-way valve 603, which can ensure that when one group of water pumps 6 fails, the other group of water pumps 6 can operate normally, and the idle water pumps 6 will not reverse the water supply.

[0042] When rainwater accumulates, it will enter the water inlet tank 7, and the float block 10 will be lifted by buoyancy. When the float block 10 rises, it will push a group of arc bars 9 forward. The arc bars 9 move forward through the slide groove 902 and the guide member 8, and the metal cylinder 904 contacts the contact member 803. The LED light 905 is energized through the contact member 803, so that the LED light 905 lights up, and the displayed color has a warning effect, which can help subway drivers and patrol personnel identify the water level.

[0043] After the accumulated water is removed, the floating block 10 can automatically drop with the water level, and the weight of the floating block 10 pushes the arc bar 9 away, thereby ensuring that the floating block 10 falls naturally.

[0044] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0045] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
