In the case of heavy rain, pipeline rupture, fire protection system failure, etc., it can quickly and efficiently drain the accumulated water out of the subway station to ensure the safety of passengers' lives and the normal operation of subway facilities.

[0003] In some existing emergency drainage devices, generally, a water pump is used to extract and drain the accumulated water in the subway station. Since the depth of the accumulated water in the subway station may be different, when specifically pumping the accumulated water with different depths, it is necessary to adjust the height position of the external water suction pipe of the water pump in the water to extract the accumulated water to the greatest extent. In some existing technologies, the process of adjusting and fixing the height of the water suction pipe is relatively troublesome. For example, the emergency drainage device disclosed in the publication number CN220539983U needs to rotate the bidirectional lead screw for a long time to change the height of the water suction pipe during actual use. When there is a large amount of accumulated water and the situation is relatively urgent, the adjustment cannot be quickly completed for pumping water, which affects the pumping efficiency and the emergency effect is poor. Therefore, an emergency drainage device for subway stations is proposed for the above problems. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 6 shown, the present utility model provides an emergency drainage device for a subway station, including a base 1. The outer wall of the top end of the base 1 is fixedly connected with a water pump 2. The outer wall of the front end of the water pump 2 is fixedly connected with a water suction pipe 3. The inner wall of the bottom end of the base 1 is slidably connected with a moving plate 5. The inner wall of the moving plate 5 is provided with a moving mechanism 6. The outer wall of the top end of the moving plate 5 is provided with an adjusting mechanism 4. The adjusting mechanism 4 includes a partition board 401. The outer wall of the partition board 401 is slidably connected with a moving rod 402. The outer wall of the top end of the moving rod 402 is fixedly connected with a fixed ring 403. The outer wall of the bottom end of the moving rod 402 is hinged with a slide block 405 through a rotating rod 404. The outer wall of the bottom end of the slide block 405 is fixedly connected with a moving block 406. The outer wall of the moving block 406 is hinged with a pull rod 408 through a connecting rod 407. The outer wall of the top end of the pull rod 408 is provided with a card slot 409. The outer wall of the top end of the moving plate 5 is fixedly connected with a fixed block 410. The inner wall of the fixed block 410 is elastically connected with an insert block 412 through a telescopic spring 411. The outer wall of the moving plate 5 is provided with a groove 413.

[0024] Adopt the above solution: By placing the base 1 on the ground, the submersible pump 2 can be started to suck and discharge the accumulated water on the ground in the subway station. The submersible pump 2 and the suction pipe 3 are well-known prior arts to those skilled in the art and will not be elaborated here. When it is necessary to use the suction pipe 3 for pumping water, the suction pipe 3 needs to be placed in the accumulated water, and the accumulated water is sucked in by the suction force of the submersible pump 2. Through the two fixing rings 403 in the adjusting mechanism 4, the movable end of the suction pipe 3 can be fixed and supported to keep its position fixed during the pumping process. Moreover, the height of the fixing ring 403 can be adjusted through the adjusting mechanism 4 to adjust the height of the movable end of the suction pipe 3 according to the depth of the accumulated water in the subway station. The adjustment process is relatively convenient, and the adjustment and fixation of the suction pipe 3 can be quickly completed during emergencies for pumping water. When the moving plate 5 and the adjusting mechanism 4 are not in use, they can be stored inside the base 1 to save occupied space, and the position of the moving plate 5 can be fixed through the moving mechanism 6. A plurality of limiting grooves are formed on both sides of the inner wall of the base 1. By engaging the clamping block 605 with the corresponding limiting groove, the position of the moving plate 5 can be adjusted and fixed.

[0025] As Figures 2 to 4 shown, the partition plate 401 is fixedly connected to the outer wall of the top end of the moving plate 5. One end of the rotating rod 404 is hinged to the outer wall of the bottom end of the moving rod 402, and the other end of the rotating rod 404 is hinged to the outer wall of the top end of the slider 405. The slider 405 is slidably connected to the outer wall of the top end of the moving plate 5. One end of the connecting rod 407 is hinged to the outer wall of the pull rod 408, and the other end of the connecting rod 407 is hinged to the outer wall of the moving block 406. The outer wall of the pull rod 408 is in contact with the inner wall of the groove 413. The pull rod 408 is slidably connected to the inner wall of the moving plate 5. One end of the telescopic spring 411 is fixedly connected to the outer wall of the plug 412, and the other end of the telescopic spring 411 is fixedly connected to the inner wall of the fixed block 410. The outer wall of the plug 412 is slidably connected to the inner wall of the fixed block 410, and the plug 412 is engaged with the card slot 409.

[0026] Adopting the above solution: There are two sets of partition plates 401, symmetrically distributed on the outer walls of the two top ends of the moving plate 5. There are two sets of moving rods 402, and both sets of moving rods 402 are slidably connected to the outer walls of the partition plates 401. One set of fixing rings 403 is arranged on each set of moving rods 402. Without the influence of external forces, the telescopic spring 411 drives the plug 412 to pop downward due to its own elastic force and is clamped with the clamping groove 409, so that the position of the pull rod 408 can be fixed. When the position of the pull rod 408 is fixed, the two connecting rods 407 are in a fixed state, so that the moving block 406, the sliding block 405, the rotating rod 404 and the moving rod 402 are all in a fixed state. When the plug 412 is pulled upward to disengage it from a set of clamping grooves 409, the limit of the pull rod 408 can be released to move it. When the pull rod 408 moves into the inner wall of the moving plate 5, it can drive the two connecting rods 407 to turn outward, driving the sliding block 405 and the moving block 406 to move. Since the sliding block 405 is slidably connected to the outer wall of the top end of the moving plate 5, the two move horizontally to both sides at the same time. During this process, the sliding block 405 can drive the two rotating rods 404 to turn at the same time, driving the moving rod 402 to move. Since the partition plate 401 plays a guiding role for the moving rod 402, the moving rod 402 moves vertically downward, and the height of the fixing ring 403 can be adjusted downward, so that the movable end of the water suction pipe 3 moves downward to adapt to shallower accumulated water.

[0027] Conversely, when the pull rod 408 is pulled outward, the two moving rods 402 and the fixing ring 403 can be moved upward, driving the movable end of the water suction pipe 3 to move upward, which is applicable to areas with deeper accumulated water. After the height of the water suction pipe 3 is adjusted by moving the pull rod 408, the plug 412 can be released. Under the elastic force of the telescopic spring 411, the plug 412 pops downward and is clamped with a corresponding set of clamping grooves 409. The height of the water suction pipe 3 can be adjusted through the adjusting mechanism 4. And there are multiple sets of clamping grooves 409, and the pull rod 408 can be moved to multiple positions for fixation to adapt to various water depths, with high adaptability and a relatively fast adjustment process. The operation can also be quickly completed in a relatively urgent situation, improving the drainage efficiency.

[0028] As Figure 5 shown, the moving mechanism 6 includes a handle 601. A sliding plate 602 is slidably connected to the outer wall of the handle 601. A traction rope 603 is slidably connected to the inner wall of the moving plate 5. A clamping block 605 is elastically connected to the inner wall of the moving plate 5 through a connecting spring 604. A rotating wheel 606 is rotatably connected to the inner wall of the moving plate 5.

[0029] The handle 601 is fixedly connected to the outer wall of the front end of the moving plate 5. One end of the towing rope 603 is fixedly connected to the outer wall of the sliding plate 602, and the other end of the towing rope 603 is fixedly connected to the outer wall of the clamping block 605. The towing rope 603 is wound around the outer wall of the rotating wheel 606. One end of the connecting spring 604 is fixedly connected to the outer wall of the clamping block 605, and the other end of the connecting spring 604 is fixedly connected to the inner wall of the moving plate 5. The outer wall of the clamping block 605 is slidably connected to the inner wall of the moving plate 5, and the clamping block 605 is clamped with the inner wall of the base 1.

[0030] Adopting the above solution: By holding the handle 601 and pulling the sliding plate 602, one end of the towing rope 603 can be driven to move. When it moves, it drives the rotating wheel 606 to rotate. The rotating wheel 606 changes the pulling force direction of the towing rope 603, and the other end of the towing rope 603 can be made to pull the clamping block 605 to move. There are two sets of the towing rope 603, the rotating wheel 606 and the clamping block 605 respectively. Thus, by pulling the sliding plate 602, the two sets of clamping blocks 605 can be driven to move towards the middle simultaneously. The connecting spring 604 is stressed and contracts. The clamping block 605 is disengaged from contact with one set of limiting grooves in the base 1, and the limit of the moving plate 5 can be released. The moving plate 5 is pulled out so that the water suction pipe 3 can suck in the accumulated water at a farther distance. When the moving plate 5 is pulled out to a proper position, the sliding plate 602 can be released. Under the elastic force of the connecting spring 604, the two sets of clamping blocks 605 pop out towards both sides simultaneously and are clamped with the corresponding limiting grooves, and the position of the moving plate 5 can be fixed. Since the moving plate 5 and the base 1 always maintain a relatively connected state, during the water pumping process of the water suction pipe 3, the moving plate 5 and the water suction pipe 3 will not move due to excessive water flow impact force, affecting the water pumping effect.

[0031] The working principle and usage process of the present utility model:

[0032] When there is accumulated water in the subway station and emergency drainage is required, first place the base 1 at a proper position on the ground. By holding the handle 601 and pulling the sliding plate 602, the other end of the towing rope 603 pulls the clamping block 605 to move towards the middle, disengaging from the limiting grooves on both inner walls of the base 1, releasing the limit of the moving plate 5. After pulling the moving plate 5 out of the inside of the base 1 to a proper position, release the sliding plate 602. Under the elastic force of the connecting spring 604, the two sets of clamping blocks 605 pop out towards both sides simultaneously and are clamped with the corresponding limiting grooves, fixing the position of the moving plate 5.

[0033] Then, the water pump 2 can be started to suck in and discharge the accumulated water on the ground in the subway station through the water suction pipe 3. First, the water suction pipe 3 can be pulled out and placed in the fixing ring 403 so that the movable end of the water suction pipe 3 is in the accumulated water. Then, the insertion block 412 is pulled upward to disengage it from a set of clamping grooves 409, releasing the limit of the pull rod 408. The pull rod 408 is pulled outwards, driving the two connecting rods 407 to flip, causing the slider 405 and the moving block 406 to move horizontally towards the middle. The slider 405 drives the two rotating rods 404 to flip simultaneously, driving the moving rod 402 to move vertically upwards, adjusting the height of the fixing ring 403 upwards, and moving the movable end of the water suction pipe 3 upwards to adapt to deeper accumulated water. When the pull rod 408 is pushed inwards, the two moving rods 402 and the fixing ring 403 move downwards, driving the movable end of the water suction pipe 3 to move downwards, which is applicable to areas with shallower accumulated water.

[0034] When the height adjustment of the water suction pipe 3 is completed by moving the pull rod 408, the insertion block 412 is released. Under the elastic force of the telescopic spring 411, the insertion block 412 pops out downwards and is clamped with a corresponding set of clamping grooves 409, completing the height adjustment of the water suction pipe 3. There are multiple sets of clamping grooves 409, and the pull rod 408 can be moved to multiple positions for fixation to adapt to various water depths. Moreover, the adjustment mechanism 4 can complete the height adjustment of the water suction pipe 3 relatively quickly, and can quickly fix the height of the water suction pipe 3 in an emergency situation, improving the pumping efficiency. And since the moving plate 5 is connected to the base 1, during the pumping process of the water suction pipe 3, the problem that the water suction pipe 3 is affected by the impact force and moves, affecting the pumping effect due to excessive water flow can be avoided.
