[0034] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a drainage device for an airport regulating water reservoir, comprising a raft 1, a track foundation 2 and a pump pit 3 connected in sequence;

[0036] The raft 1 is arranged on the top of the slope of the airport regulating water storage tank, the track foundation 2 is arranged on the slope of the airport regulating water storage tank, and the pump pit 3 is arranged at the bottom of the airport regulating water storage tank to collect the stagnant water at the bottom of the airport regulating water storage tank;

[0037] At least one set of tracks is provided on the track foundation 2 along the slope. A pump truck 5 carrying a water pump 6 is slidably installed on each set of tracks. A winch 4 is provided at the installation area corresponding to each set of tracks on the raft 1. The end of the steel cable of the winch 4 is connected to the pump truck 5, which is used to drive the pump truck 5 carrying the water pump 6 on the track to approach or move away from the pump pit 3. It should be noted that the pump truck 5 is a four-wheeled vehicle for installing the water pump 5, and the pump pit 3 is the working space of the water pump, which is used to collect water flow.

[0038] The drainage device for the airport regulating water tank of this embodiment is as follows: when draining, the pump truck 5 carrying the water pump 6 is lowered into the pump pit 3 along the track by the winch 4, and then the stagnant water collected in the pump pit 3 is extracted by the water pump 6; when repairing, the pump truck 5 carrying the water pump 6 can be pulled up to the top of the slope along the track by the winch 4, and then the water pump 6 can be repaired.

[0039] In this embodiment, the raft 1, track foundation 2 and pump pit 3 are integrally cast by reinforced concrete. The purpose of such a configuration is to ensure the stability of the drainage device for the airport water storage tank of this embodiment on the slope of the water storage tank.

[0040] Furthermore, the raft slab 1 is composed of a bottom plate, beams, etc. The building load is large and the bearing capacity of the foundation is weak. Concrete bottom plates and raft slabs are often used to bear the building load to form a raft foundation, which has good integrity and can well resist uneven foundation settlement.

[0041] In this embodiment, the drainage device for the airport water storage tank further includes a soft-hard combined drainage pipe, which includes a soft pipe section and a hard pipe section connected to the soft pipe section;

[0042] Each set of tracks includes two steel rails 201. A groove 203 for placing a soft and hard combined drainage pipe is opened between the two steel rails 201 in the track foundation 2. A steel casing 101 is provided at the corresponding groove 203 inside the raft 1. The water outlet of the water pump 6 is connected to one end of the hose section, and the other end of the hose section is connected to one end of the hard pipe section. The other end of the hard pipe section passes through the steel casing 101, and the hard pipe section and the steel casing 101 are sealed and fixedly connected.

[0043] The drainage device for the airport regulating water tank of this embodiment adopts a soft and hard combined drainage pipe. When the water pump 6 is pulled up, the soft pipe section can be bent and stored, which solves the problem of retracting and extending the water pump 6. The sealed and fixed connection between the hard pipe section and the steel casing 101 can prevent rainwater erosion or foreign matter from entering and causing blockage.

[0044] Optionally, the hose section is a TPU hose, and the hard pipe section is a steel-framed polyethylene hard pipe.

[0045] Optionally, the track foundation 2 of this embodiment is provided with a walkway 202 along the inclination direction of the slope. The walkway 202 is a concrete pedestrian step that can be used for workers to walk on, achieving the purpose of convenient maintenance and silt removal.

[0046] Optionally, a window 301 is provided on the sidewall of the pump pit 3, connecting to a drainage ditch at the bottom of the airport's water storage tank. This direct connection between window 301 and the drainage ditch at the bottom of the tank optimizes the water collection process. The overall design demonstrates a high degree of system integration and practicality, ensuring that the airport's water storage tank can quickly and efficiently drain water, maintaining operational safety.

[0047] In this embodiment, two sets of tracks and two pump trucks 5 carrying water pumps 6 are provided on the track foundation 2. The advantages of such a configuration are mainly two-fold. On the one hand, the drainage device of this embodiment can determine the number of pump trucks 5 to be lowered according to the amount of accumulated water in the pump pit 3. That is, when the amount of accumulated water is large, both pump trucks 5 carrying water pumps 6 are lowered into the pump pit 3 to perform pumping work. When the amount of accumulated water is small, only one pump truck 5 carrying water pump 6 is lowered into the pump pit 3 to perform pumping work. On the other hand, the two pump trucks 5 carrying water pumps 6 can be alternately lifted to the top of the slope for maintenance, which can ensure that at least one pump truck 5 carrying water pump 6 is performing drainage work in the pump pit 3, forming a double insurance.

[0048] In this embodiment, the steel cable of the hoist 4 is provided with a cable flag near the pump truck 5. The purpose of providing the cable flag is to reduce the risk of rebounding and injuring people when the steel cable breaks.

[0049] Combine Figure 4 As shown, the drainage device for the airport regulating water tank of this embodiment also includes a steel wire rope 205 and two mounting brackets (not shown in the figure).

[0050] One of the two mounting brackets is set on the track foundation 2, and the other mounting bracket is set on the pump pit 3. A steel wire rope 205 is laid between the tops of the two mounting brackets, parallel to the moving direction of the pump truck 5. The power cord 204 of the water pump 6 is connected to the external power supply located at the top of the slope of the airport's regulating water tank. A plurality of connecting ropes 206 are evenly arranged between the power cord 204 and the steel wire rope 205. The lower end of the connecting rope 206 is fixedly connected to the power cord 204, and the upper end of the connecting rope 206 is connected to a ring 207. The ring 207 is set on the periphery of the steel wire rope 205 and is in sliding contact with the steel wire rope 205. Due to the above-mentioned structure, the drainage device for the field regulating water tank can keep the power cord 204 suspended in the air, preventing the power cord 204 from being worn when dragging on the ground when moving, and achieving the purpose of safely retracting and releasing the power cord 204.

[0051] When using the drainage device for the airport water storage tank of this embodiment, the following matters need to be noted:

[0052] 1. Regularly check the connection between the steel casing 101 and the hard pipe section: Ensure that the pre-buried steel casing 101 and the hard pipe section are tightly connected without leakage. Regularly check the sealing of the interface to prevent erosion by rainwater or blockage caused by foreign matter.

[0053] 2. Track foundation 2 maintenance: Regularly clean the track foundation 2 and the grooves 203 on both sides to prevent debris accumulation that affects the smoothness and safety of the pump truck 5. Check the fixed state of the track to prevent loosening and ensure the stable operation of the pump truck 5.

[0054] 3. Maintenance of soft and hard combined drainage pipes: Pay special attention to the sealing and wear of the joints between the soft pipe section and the hard pipe section, as this part is easily affected by temperature changes and water flow impact. Regularly replace the severely worn parts to keep the drainage unobstructed.

[0055] 4. Electrical system safety inspection: The power cord 204, as the power supply, needs to be regularly inspected to ensure that its insulation layer is intact and the contact points are clean to prevent leakage accidents. At the same time, ensure that all electrical connections are waterproof and moisture-proof and meet safety standards.

[0056] 5. Maintenance of winch 4: Regularly lubricate and perform functional tests on winch 4 to improve the reliability and emergency handling capabilities of the system.

[0057] 6. Cleaning of pump pit 3 and drainage ditch: Regularly clean the sediment in pump pit 3 and the drainage ditch at the bottom of the pool to prevent silt accumulation from affecting drainage efficiency and the normal operation of the pump, and maintain good hydraulic conditions.
