[0016] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: 1. This scheme adopts the cooperation of drainage device, water pipe, water outlet, water pump, height adjustment device, telescopic device, fixed plate, sliding hole, water inlet, telescopic tube and rubber scraper. By lowering the water pump to a suitable water level and starting it, the water pump can absorb the accumulated water in the foundation pit. The telescopic device and the telescopic tube are connected together through the telescopic tube, so that the suction force generated by the water pump can absorb water through the telescopic device. The telescopic tube can be extended and retracted as the telescopic device is extended and retracted. When the telescopic device is extended and retracted, the rubber scraper will scrape off the debris inside the input end of the telescopic device to prevent affecting the water intake efficiency of the telescopic device. The cooperation of the fixed plate and the sliding hole enables the height adjustment device to drive the entire device to slide up and down along the connecting rod, thereby improving the adaptability of the device.

[0017] 2.

The filter element can prevent the water pump from sucking in debris when absorbing the accumulated water in the foundation pit. When the filter element has poor passing efficiency, the filter element can be pulled out through the filter element inlet and replaced with a new one. When the water pump generates suction, the accumulated water will flow into the interior of the water pump along the filter element. Under the impact of the water flow, the filter element will not become loose. The driving motor drives the impeller to rotate. The impeller rotates inside the side plate and is fixed to the top surface of the water pump. When the impeller rotates, the pull rope will be reeled in. The outer surface of the pull rope slides inside the fixed pulley, so that the height adjustment device can drive the drainage device to rise and fall. The other end of the pull rope is fixed to the top surface of the water inlet, so that the device is more stable when rising, thereby improving the adaptability of the device.

[0018] 3. This scheme adopts the cooperation of a fixing mechanism, a water tank, a water inlet, a drain outlet, a buffer spring, a depth adjustment device, a high-strength top plate, a limit block, a bolt, a fixed pulley, a sliding rod, and a connecting rod, so that the accumulated water absorbed by the drainage device is transported to the inside of the water tank through the water inlet, and the accumulated water will be temporarily stored inside the water tank. As the accumulated water is injected, the weight of the water tank increases, making the entire device more solid, and the accumulated water inside the water tank can be discharged through the drain outlet. The high-strength top plate is fixed to the top surface of the water tank and the sliding rods on the bottom surface thereof play the effect of supporting the drainage device. The buffer spring can buffer the deformation of the high-strength top plate when supporting the drainage device to prevent the high-strength top plate from breaking due to excessive deformation. The depth that the drainage device can reach can be controlled by controlling the number of sliding rods. Multiple sliding rods are connected by connecting rods and bolts, which will not affect the normal sliding of the drainage device on the surface of the sliding rods. The limit block can prevent the drainage device from slipping, thereby improving the adaptability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

9. A foundation pit drainage device for water conservancy and hydropower construction according to claim 8, characterized in that: The connecting rod (156) is movably connected to the inside of the top surface of the sliding rod (155); one end of the outer surface of the sliding rod (155) is internally threadedly connected to a bolt (153); one end of the bolt (153) passes through the inside of the top surface of the sliding rod (155) and is threadedly connected to the inside of the side surface of the connecting rod (156); and the bottom surface of the sliding rod (155) is movably connected to a limiting block (152).

10. A method for using a foundation pit drainage device for water conservancy and hydropower construction, applicable to a foundation pit drainage device for water conservancy and hydropower construction as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1, installation preparation: fix the water tank (11) at the foundation pit where drainage is required, and fix the water pipe (21) inside the water outlet (22) and the water outlet (12) respectively. According to the depth of the foundation pit where drainage is required, combine a suitable number of slide bars (155) together, pass the slide bar (155) through the slide hole (27) while the slide bar (155) is being moved, and install a limit block (152) on the bottom surface of the lowest end of the slide bar (155). Pass the pull rope (244) around the fixed pulley (154) and fix it on the top surface of the fixed block (245). Drive the driving motor (246) to make the pull rope (244) in a taut state. At this time, the drainage device (2) is lifted without affecting the installation of the slide bar (155). Insert the filter element (256) from the open end of the filter element inlet (255), and assemble the entire device. Step 2, adjustment process: turn on the drive motor (246) to slowly release the rolled-up pull rope (244), and under the influence of the drainage device (2)'s own gravity, the entire device slides down along the slide bar (155) to a suitable position. At this time, the drive motor (246) stops moving and fixes the entire device in a suitable position. At this time, the telescopic rod (251) extends the support rod (252) to drive the outer frame (254) to extend forward. The telescopic tube (29) fixedly connected to the outer frame (254) will extend and retract as the outer frame (254) retracts and retracts. The rubber scraper (210) will scrape off debris attached to the input end of the outer frame (254) during the process of the outer frame (254) retracting and retracting. Step 3, drainage process: the water pump (23) is driven to generate suction, and the accumulated water will enter the interior of the filter element (256) through the outer frame (254) and be filtered. The water will be transported to the interior of the water tank (11) and temporarily stored through the cooperation of the water pump (23) and the water pipe (21). The water inside the water tank (11) will be discharged through the drain port (13). When a puddle appears in the foundation pit, the outer frame (254) is extended to the puddle by controlling the telescopic rod (251), and the suction generated by the water pump (23) will suck away the water inside.
