Description

Technical Field

[0001] This utility model relates to the field of drainage equipment, and in particular to a drainage vehicle and its suction pipe. Background Technology

[0002] A drainage vehicle (such as a mobile pumping station) is a mobile drainage device used for emergency rescue, disaster relief, and municipal drainage. It is usually equipped with a variety of drainage accessories, among which the suction pipe is one of its core components. In actual operation, the suction pipe is attached to the inlet of the pump unit of the drainage vehicle, and the suction pipe is extended into the waterlogged area. The negative pressure generated by the pump unit draws in water and discharges it.

[0003] Common suction pipes typically use a simple cylindrical tube with a cylindrical filter cartridge fitted at the inlet. The filter cartridge prevents the intake of large impurities, avoiding clogging or damage to the pump impeller. However, this type of suction pipe has a significant drawback: during pumping operations, the entire filter cartridge must always be completely submerged below the water surface. If the water level drops and the filter screen partially emerges, the pump will draw in air, reducing pumping efficiency, interrupting drainage, and potentially damaging the pump itself. This results in incomplete drainage, leaving a persistently high level of water. Utility Model Content

[0004] Therefore, it is necessary to provide a drainage vehicle and its suction pipe, which can draw water from low liquid levels.

[0005] To achieve the above objectives, the inventor provides a water suction tube, comprising:

[0006] tube body;

[0007] A filter assembly, comprising a housing and a filter screen, wherein the housing has an internal water channel, and the side of the housing has an interface communicating with the water channel, the interface being connected to the port of a pipe body; the bottom edge of the housing has a slot communicating with the water channel, and the filter screen is disposed in the slot; and

[0008] A lifting assembly, which is mounted on the housing, is used to adjust the ground clearance of the housing.

[0009] Furthermore, the side of the housing is also provided with a connecting plate, and the lifting assembly includes a lifting component and a support component. The lifting component is disposed on the support component and connected to the connecting plate, and is used to lift the connecting plate to adjust the ground clearance of the housing.

[0010] Furthermore, the support component is a pulley assembly.

[0011] Furthermore: one of the lifting components and one of the supporting components form a unit group, and there are multiple unit groups.

[0012] Furthermore: there are four groups of units, which are evenly distributed on both sides of the housing, and each group of units corresponds to one connecting plate.

[0013] Furthermore: the lifting assembly includes a screw, an upper nut, and a lower nut; the connecting plate has an opening; the screw passes through the opening; the screw is mounted on the support assembly; the upper nut is threadedly connected to the screw; the lower nut is threadedly connected to the screw; and the upper nut and the lower nut lock the connecting plate from the upper and lower sides.

[0014] Furthermore: the upper nut is a wing nut, and the lower nut is a hexagonal nut.

[0015] Furthermore: the slot is a square hole, and the filter screen is a square filter screen.

[0016] Furthermore: the interface is sleeved with the port of the pipe body and fixed by a clamp.

[0017] To achieve the above objectives, the inventors also provide a drainage vehicle, comprising:

[0018] A mobile chassis;

[0019] A pump unit, which is mounted on the mobile chassis;

[0020] The suction pipe is the suction pipe described in any of the above embodiments, and the port of the suction pipe away from the filter assembly is connected to the water inlet of the pump device.

[0021] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0022] The lifting assembly allows for flexible control of the filter assembly's height above the ground, enabling precise adjustment of the water level and improving the adaptability of the suction pipe. The filter screen is located at the bottom of the filter assembly, and the lifting assembly can be used to adjust the filter assembly to its lowest position. This ensures that even in low water levels or shallow water, the filter screen remains fully submerged, effectively removing accumulated water or sediment from the bottom and improving the thoroughness of drainage.

[0043] Please see Figures 1 to 5 This application provides a water suction tube 1, comprising:

[0044] Pipe body 11 is a flexible pipe of a certain length, used to connect to the inlet of the pump device 22 of the drainage vehicle 2 and to introduce water into the pump device 22;

[0045] The filter assembly 12 includes a housing 121 and a filter screen 122. The housing 121 has an internal water channel, and its side has an interface 123 communicating with the water channel. The interface 123 connects to the port of the pipe body 11. The bottom edge of the housing 121 has a slot communicating with the water channel. The filter screen 122 is located in the slot to intercept impurities in the water and prevent them from entering the pump body.

[0046] Lifting assembly 13 is mounted on housing 121 and is used to adjust the ground clearance of housing 121.

[0047] The lifting assembly 13 is used to control the lifting of the housing 121, thereby adjusting the ground clearance between the housing 121 and the ground. When the housing 121 rises, the ground clearance increases; when the housing 121 falls, the ground clearance decreases.

[0048] The lifting assembly 13 allows for flexible control of the filter assembly 12's height above the ground, enabling precise adjustment of the water level and improving the adaptability of the suction pipe 1. The filter screen 122 is located at the bottom of the filter assembly 12, and the lifting assembly 13 allows the filter assembly 12 to be adjusted to its lowest position. This ensures that even in low water levels or shallow water conditions, the filter screen 122 remains fully submerged, effectively removing accumulated water or sediment from the bottom and improving the thoroughness of drainage.

[0049] Please see Figure 3 , Figure 4 and Figure 5In some embodiments, a connecting plate 124 is also provided on the side of the housing 121. The lifting assembly 13 includes a lifting component 131 and a support component 132. The lifting component 131 is disposed on the support component 132 and connected to the connecting plate 124, and is used to lift the connecting plate 124 to adjust the ground clearance of the housing 121. The support component 132 provides a mounting fulcrum for the lifting component 131 and supports the filter assembly 12 on the ground. When it is necessary to increase the ground clearance of the housing 121, the lifting component 131 pushes the connecting plate 124 upward, causing the housing 121 to move upward as a whole; conversely, when it is necessary to decrease the ground clearance, the lifting component 131 pulls the connecting plate 124 downward, causing the housing 121 to descend as a whole.

[0050] Please see Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the support component 132 is a pulley assembly for sliding on the ground, thereby allowing the entire suction pipe 1 to be adjusted synchronously with the movement of the drainage vehicle 2. In some embodiments, the support component 132 may not use a pulley assembly, but rather other structures that can slide on the ground, such as an arc-shaped sliding plate disposed at the bottom of the housing 121. In other embodiments, the support component 132 may be a support column.

[0051] Please see Figure 3 , Figure 4 and Figure 5 In some embodiments, a lifting component 131 and a support component 132 form a unit group 133. There are multiple units 133, which can support and adjust the housing 121 at different positions to avoid structural imbalance or tilting caused by a single support point.

[0052] Please see Figure 5 In a preferred embodiment, there are four groups of unit groups 133, which are evenly distributed on both sides of the housing 121, with each group of unit groups 133 corresponding to a connecting plate 124. Specifically, the four groups of unit groups 133 are arranged in two rows and two columns, at the front left, front right, rear left, and rear right positions of the housing 121. Each group of unit groups 133 includes a lifting component 131 and a supporting component 132, and is connected to the housing 121 through a corresponding connecting plate 124 to ensure coordinated control of lifting and sliding at different positions. In other embodiments, the number of unit groups 133 can be flexibly configured according to the actual application scenario, such as two, three, five, or six groups, and distributed at different positions of the housing 121 as needed.

[0053] Please see Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the lifting assembly 131 includes a screw 1311, an upper nut 1312, and a lower nut 1313. The connecting plate 124 has an opening through which the screw 1311 passes. The screw 1311 is mounted on the support assembly 132. The upper nut 1312 is threadedly connected to the screw 1311, and the lower nut 1313 is also threadedly connected to the screw 1311. The upper nut 1312 and lower nut 1313 lock the connecting plate 124 from its upper and lower sides. By rotating the upper nut 1312 or the lower nut 1313, the connecting plate 124 can be loosened or locked. Subsequently, by moving the screw 1311 up and down, the height of the housing 121 can be adjusted. Finally, by rotating the upper nut 1312 and lower nut 1313, the connecting plate 124 is re-locked in its new position, ensuring structural stability. In other embodiments, the lifting assembly 131 is a cylinder, a hydraulic cylinder, or an electric actuator.

[0054] Please see Figure 4 In some embodiments, the upper nut 1312 is a wing nut and the lower nut 1313 is a hexagonal nut, which is convenient for manual tightening.

[0055] Please see Figure 2 In some embodiments, the slot is a square hole and the filter screen 122 is a square filter screen 122, which can adapt to pumping operations at lower water levels.

[0056] Please see Figure 1 and Figure 3 In some embodiments, the interface 123 is sleeved onto the port of the pipe body 11 and secured with a clamp. After the interface 123 is inserted into the port of the pipe body 11, the clamp is used to fix the interface 123 to the pipe body 11 to prevent loosening or falling off during use. In other embodiments, the interface 123 and the pipe body 11 may not be secured with a clamp, but rather with a quick-connect coupling such as a three-jaw connector.

[0057] Please see Figures 1 to 6 This application also provides a drainage vehicle, the drainage vehicle 2 comprising:

[0058] Walkable chassis 21;

[0059] Pump device 22, which is mounted on a mobile chassis 21;

[0060] The suction pipe 1 is the suction pipe 1 described in any of the above embodiments. The port of the suction pipe 11 away from the filter assembly 12 is connected to the water inlet of the pump device.

[0061] The chassis 21 can be a tracked chassis 21 or a wheeled chassis 21 to adapt to different terrain conditions.

[0062] The pump device is mounted on the chassis 21. It is preferably a vacuum pump. It draws water from the outside of the suction pipe 1 into the pump casing by generating negative pressure, and then the pump device delivers and discharges the water.

[0063] In some embodiments, a power unit may be mounted on the chassis 21 to provide power to the pump unit and the chassis 21. In some embodiments, the chassis 21 may not require a power unit, and the power to the pump unit and the chassis 21 may be provided by other vehicles.

[0064] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
