However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0024] like Figures 1-3 As shown, a waterproof drainage device for subway tunnels includes a mobile frame 1, a water tank 2 inside the mobile frame 1, a water inlet at the upper end of the water tank 2, and a lifting mechanism on the mobile frame 1 for driving the water tank 2 to move longitudinally back and forth within the mobile frame 1. When the water tank 2 moves upward, it has a storage position inside the mobile frame 1, and when the water tank 2 moves downward, it has a placement position where the bottom of the water tank 2 contacts the ground. A hose reel 5 is provided at one end of the mobile frame 1, and a water pipe 6 connected to the water tank 2 is wound on the hose reel 5.

[0025] In this embodiment, when water leakage occurs in the tunnel, a tool cart or by directly pushing the handle 4 is used to push the mobile frame 1 to the leaking point in the tunnel. During the movement of the mobile frame 1, the water tank 2 is in the storage position to prevent the water tank 2 from rubbing against the ground and increasing resistance. When the mobile frame 1 moves to the designated position, the lifting mechanism is activated to control the water tank 2 to move down to the placement position, so that the bottom of the water tank 2 contacts the ground, so that the ground can bear the weight of the water tank 2. At the same time, the water inlet on the water tank 2 is aligned with the water flow, and the water tank 2 temporarily stores the leaked water. Meanwhile, people pull the water pipe 6 on the hose reel 5 to pull it to the outside of the tunnel or to the drainage ditch inside the tunnel. Through the external water pump 7, the water stored in the water tank 2 is quickly pumped out and discharged through the drainage ditch to prevent water from overflowing, affecting construction, and damaging electrical equipment placed on the ground.

[0026] like Figure 3As shown, the lifting mechanism is a cylinder 3 fixedly arranged on the mobile frame 1, and at least four are arranged along the four corners of the water tank 2, and the output end of each cylinder 3 is fixedly connected with the upper end of the water tank 2.

[0027] In this embodiment, by arranging the cylinder 3, when the mobile frame 1 pulls the water tank 2 to the storage position during movement, the friction between the water tank 2 and the ground is prevented from increasing the resistance, and when the water tank 2 needs to store water, in order to avoid the weight being too large to damage the mobile frame 1, the cylinder 3 is started to control the water tank 2 to move to the placement position, so that the bottom of the water tank 2 is in contact with the ground, and the ground bears the load of the water tank 2.

[0028] As shown in Figure 3 , the inside of the water tank 2 is provided with a water pump 7, and the water outlet end of the water pump 7 is connected in communication with the water inlet end of the water pipe 6.

[0029] In this embodiment, by arranging the water pump 7, when the water level in the water tank 2 exceeds the water pump 7, the water stored in the water tank 2 is discharged to the drain through the water pipe 6 by starting the water pump 7.

[0030] As shown in Figure 3 , the inside of the water tank 2 is provided with a water level monitor 8, and the outside of the water tank 2 is provided with a water level alarm indicator 12.

[0031] In this embodiment, by arranging the water level monitor 8, when the water level is higher than the water pump 7, the water level alarm indicator 12 turns green, reminding people to start the water pump 7 to pump water, and when the water level is lower than the water pump 7, the water level alarm indicator 12 turns red to remind people to turn off the water pump 7.

[0032] As shown in Figure 1 , a water pump starting button 13 is arranged on the water tank 2, and the water pump starting button 13 is electrically connected with the water pump 7.

[0033] In this embodiment, by arranging the water pump starting button 13, the water pump 7 can be quickly started and stopped, which is convenient for people to operate.

[0034] As shown in Figure 3 , a water collecting bucket 10 is arranged on the mobile frame 1, the lower end of the water collecting bucket 10 is connected with a telescopic pipe 9, the lower end of the telescopic pipe 9 is connected in communication with the water inlet of the water tank 2, and the inside of the water collecting bucket 10 is provided with a protective net 11.

[0035] In this embodiment, by arranging the water collecting bucket 10, the water collecting range is increased, and when the water tank 2 moves up and down by the cylinder 3, the telescopic pipe 9 has a certain telescopic space, and at the same time, the protective net 11 is arranged to intercept the gravel, preventing the gravel from entering the water tank 2 and damaging the water pump 7 and the water level monitor 8.

[0036] As shown in Figure 1 , a handle 4 is arranged on the mobile frame 1.

[0037] In this embodiment, by setting the handle 4, it is convenient for people to grasp to push the mobile frame 1 to move, or to be connected with the tool car to realize fast movement.

[0038] Working principle: when water leakage occurs in the tunnel, the tool car is used or the handle 4 is directly pushed to push the mobile frame 1 to the water leakage position in the tunnel, and in the process of moving the mobile frame 1, the water tank 2 is in the storage position to prevent the water tank 2 from being rubbed with the ground to increase the resistance, when the mobile frame 1 moves to the specified position, the water tank 2 is lowered to the placement position by starting the lifting mechanism, so that the bottom of the water tank 2 is in contact with the ground, which is used to make the ground bear the weight of the water tank 2, and at the same time, the water inlet on the water tank 2 is aligned with the water flow, in another embodiment, a water collecting bucket 10 can also be arranged above the water tank 2 to increase the water collecting area, the water tank 2 temporarily stores the leakage water, and at the same time, people pull the water pipe 6 on the pipe reel 5 to the drainage ditch outside the tunnel or in the tunnel, and through the external water pump 7, the water stored in the water tank 2 is quickly pumped out, the water pump 7 can also be arranged inside the water tank 2, and a water level monitor 8 cooperating with the water pump 7 and a water level alarm indicator 12 are arranged, when the water level is higher than the water pump 7, the water level alarm indicator 12 turns green, reminding people to start the water pump 7 to pump water, at this time, the water pump starting button 13 is pressed to start the water pump 7, and the water stored in the water tank 2 is discharged to the drainage ditch through the water pipe 6, which prevents the water from overflowing and affecting the construction, and also prevents the damage to the electrical equipment placed on the ground.
