Description

Technical Field

[0001] This utility model relates to the field of high-speed railway subgrade construction, specifically a drainage device for high-speed railway subgrade construction. Background Technology

[0002] Water is the main cause of roadbed defects, including softening of the track bed, inducing frost heave, and reducing shear strength. High-speed railways have extremely strict control over roadbed settlement. A well-designed drainage system can effectively maintain the dryness and uniform stiffness of the roadbed and ensure track smoothness.

[0003] Drainage devices can be mainly divided into the following categories: mobile emergency drainage devices, fixed drainage ditch systems, underground drainage facilities, new material drainage systems, and automatic cleaning drainage devices. Mobile emergency drainage devices are suitable for sudden water accumulation or temporary drainage needs, such as foundation pits, tunnel entrances, and other areas during rainstorms.

[0004] CN210342208U discloses a high-efficiency drainage device for high-speed railway construction. The device's inlet pipe can adjust the depth of the inlet port in the sump according to the size and depth of the sump. However, since the adjustment process requires manual adjustment, the height of the inlet end of the pipe needs to be constantly monitored. If the pipe protrudes above the water surface, the water pump will run dry. In addition, the water depth in the sump is not easily visible due to the water surface obscuring the view. If the inlet pipe is too low, it may extend into the soil of the foundation pit, causing blockage. To solve the above problems, we propose a drainage device for high-speed railway subgrade construction. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage device for high-speed railway subgrade construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a drainage device for high-speed railway subgrade construction includes a movable frame. A pusher is fixedly installed on the upper surface of the movable frame, and several casters are installed at the bottom corners of the movable frame. A drainage box is fixedly installed on the upper surface of the movable frame. The drainage box includes a water intake chamber and a water drainage chamber on both sides, as well as an equipment compartment located inside the water intake chamber and the water drainage chamber. A water intake pipe is installed inside the water intake chamber, and the water inlet end of the water intake pipe is connected to a positioning unit.

[0007] The positioning unit includes a counterweight ball, the interior of which is provided with a water suction channel communicating with a water suction pipe. A movable filter cylinder is rotatably connected to the top of the counterweight ball, and a filter cavity is formed between the inner side of the movable filter cylinder and the top of the counterweight ball. The upper end of the water suction channel extends into the interior of the movable filter cylinder and communicates with the filter cavity. A blade is fixedly installed on the end of the movable filter cylinder near the water suction channel by a bracket. A stop bar is fixedly connected to the outer wall of the counterweight ball on the outside of the movable filter cylinder.

[0008] Furthermore, the outer walls of both the water absorption chamber and the drainage chamber are slidably connected with chamber doors, and the inner walls of both the water absorption chamber and the drainage chamber are fixedly connected with several support columns.

[0009] Furthermore, the water absorption chamber is equipped with a switch inside, and the inner wall of the water absorption chamber is also equipped with a sleeve that matches the size of one end of the positioning unit.

[0010] Furthermore: the equipment compartment is equipped with a water tank, which is L-shaped.

[0011] Furthermore, the equipment compartment is also equipped with a battery and a pump, with the pump's inlet connected to the outlet of the suction pipe.

[0012] Furthermore: the lower end of the movable frame is provided with an auxiliary drainage pipe, the upper end of the auxiliary drainage pipe is connected to the interior of the water tank, and a valve is fixedly installed on the outer end of the auxiliary drainage pipe.

[0013] Furthermore, the two ends of the stop bar are lower than the middle height, and the two ends of the stop bar are in contact with the surface of the movable filter cartridge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The figure shows a preferred embodiment of the present invention, a drainage device for high-speed railway subgrade construction, including a movable frame 1, a U-shaped push frame 2 fixedly installed on the upper surface of the movable frame 1, and several universal wheels installed at the bottom corners of the movable frame 1.

[0025] A drainage box 3 is fixedly installed on the upper surface of the mobile frame 1. The drainage box 3 includes a water suction chamber 4 and a drainage chamber 5 on both sides, as well as an equipment chamber 6 located inside the water suction chamber 4 and the drainage chamber 5. A water suction pipe 7 is installed inside the water suction chamber 4, and the water inlet end of the water suction pipe 7 is connected to a positioning unit 8.

[0026] Specifically, the positioning unit 8 includes a counterweight ball 9, inside which is a water suction channel 10 communicating with the water suction pipe 7. A movable filter cylinder 11 is rotatably connected to the top of the counterweight ball 9. A filter cavity 12 is formed between the inner side of the movable filter cylinder 11 and the top of the counterweight ball 9. The upper end of the water suction channel 10 extends into the interior of the movable filter cylinder 11 and communicates with the filter cavity 12. A blade 13 is fixedly installed on one end of the movable filter cylinder 11 near the water suction channel 10 via a bracket. A stop bar 14 is fixedly connected to the outer wall of the counterweight ball 9 on the outer side of the movable filter cylinder 11. There are several blades 13 arranged in a ring shape, with a deflection angle on their surface. When positioning... When unit 8 falls into the pit, under the action of the counterweight ball 9, the positioning unit 8 acts like a self-righting toy, keeping the movable filter cylinder 11 always above the counterweight ball 9, preventing it from contacting the ground and making it less prone to clogging. It can also maintain a certain height relative to the ground for water suction. When the pump 21 starts to suction water, the water flows through the movable filter cylinder 11 and enters the suction pipe 7 in sequence from the filter chamber 12, the blades 13, and the suction channel 10. During the process, the water flow passing through the blades 13 can push the movable filter cylinder 11 to rotate on the counterweight ball 9. With the help of the baffle 14, the adhering substances brought by the water flow on the surface of the movable filter cylinder 11 can be cleaned to avoid clogging of the movable filter cylinder 11.

[0027] The outer walls of the water absorption chamber 4 and the drainage chamber 5 are slidably connected with chamber doors 15. After opening the chamber door 15, the water absorption pipe 7 and the positioning unit 8 can be removed from the water absorption chamber 4. The inner walls of the water absorption chamber 4 and the drainage chamber 5 are fixedly connected with several support columns 16. The support columns 16 can coil up the water absorption pipe 7 to prevent the water absorption pipe 7 from being stacked randomly and affecting the internal water flow.

[0028] Understandably, the suction chamber 4 is equipped with a switch 17, which controls the start-up state of the pump 21. The inner wall of the suction chamber 4 is also equipped with a sleeve 18 whose dimensions are compatible with one end of the positioning unit 8. Figure 2 As shown, the inner side of the sleeve 18 is adapted to the size of the counterweight ball 9. When the positioning unit 8 is locked inside the sleeve 18, it can lift the positioning unit 8, so that the sewage or blockage in the movable filter cartridge 11 can fall naturally under the gravitational potential energy.

[0029] In addition, a water tank 19 is installed inside the equipment compartment 6. When there is no suitable drainage location around the device, the pumped water can be stored in the water tank 19. In order to make full use of the space inside the equipment compartment 6, the water tank 19 is L-shaped. It should be noted that a drainage pump powered by a battery 20 is installed inside the water tank 19. The water inlet of the drainage pump is connected to the inside of the water tank 19, and the water outlet of the drainage pump is connected to the drain pipe. The switch 17 of the drainage pump and the water outlet of the drain pipe are both located inside the drainage compartment 5. The drainage pump and the drain pipe are not shown in the figure.

[0030] If drainage is inconvenient at the location of the device, the drainage pump needs to be started. The drainage pump will pump out the water in the water tank 19 through the drainage pipe, and the pumped water can be discharged to other places through the drainage pipe.

[0031] The equipment compartment 6 is equipped with a battery 20 and a pump 21. The inlet of the pump 21 is connected to the outlet of the suction pipe 7. The battery 20 is used to power the pump 21, so that the device can be operated anywhere without a cable. The charging port of the battery 20 is located inside the drainage compartment 5.

[0032] When the device is located in an area where drainage is possible, or when the device is moved to an area where drainage is possible, such as after leaving the construction area, the lower end of the mobile frame 1 is provided with an auxiliary drainage pipe 22. The upper end of the auxiliary drainage pipe 22 is connected to the inside of the water tank 19. A valve is fixedly installed at the outer end of the auxiliary drainage pipe 22. When the valve is opened, the water inside the water tank 19 can flow out through the auxiliary drainage pipe 22.

[0033] To facilitate scraping away dirt from the surface of the movable filter cartridge 11, the two ends of the baffle 14 are lower than the middle height, and the two ends of the baffle 14 are in contact with the surface of the movable filter cartridge 11.

[0034] In this embodiment, when the device is in use, it is first moved to the position to be pumped by the pusher 2, and the auxiliary drain pipe 22 is oriented toward the position to be drained. Then, the positioning unit 8 is thrown at the position to be pumped. Under the action of the counterweight ball 9, the positioning unit 8 is similar to a roly-poly toy, keeping the movable filter cylinder 11 always on the upper side of the counterweight ball 9, not in contact with the ground, not easy to be blocked, and able to maintain a certain height relative to the ground for water suction. When the switch 17 controls the pump 21 to start water suction, the water flows through the movable filter cylinder 11 and enters the suction pipe 7 in sequence from the filter chamber 12, the blades 13, and the suction channel 10. During the process, the water flow passing through the blades 13 can push the movable filter cylinder 11 to rotate on the counterweight ball 9. With the help of the baffle 14, the adhering substances brought by the water flow on the surface of the movable filter cylinder 11 can be cleaned to avoid clogging the movable filter cylinder 11. The water flow through the suction pipe 7 passes through the pump 21 and enters the water tank 19.

[0035] When the location of the device allows for drainage, open the valve on the auxiliary drain pipe 22, and the water inside the water tank 19 can flow directly out through the auxiliary drain pipe 22. If the location of the device is inconvenient for drainage, the drain pump needs to be started. The drain pump will pump out the water in the water tank 19 through the drain pipe, and the pumped water can be discharged to another location through the drain pipe.

[0036] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
