Description

Technical Field

[0001] This utility model relates to the field of drainage equipment or water pump technology, specifically a shallow water pumping device for small-diameter pipes. Background Technology

[0002] Small-diameter shallow water drainage equipment is mainly used in scenarios requiring the removal of shallow water within small-diameter pipes, such as drainage systems in residential buildings, high-rise buildings, municipal engineering projects, hotels, restaurants, shops, hospitals, schools, office buildings, and commercial buildings, as well as projects involving the discharge of acidic or alkaline corrosive wastewater from factories, mines, and laboratories. In these scenarios, shallow water may accumulate within the small-diameter pipes, necessitating specialized equipment for drainage.

[0003] During the construction of municipal sewage pipe networks with separate storm and sewage systems, pipes with a diameter of less than 600 mm often accumulate shallow water inside the pipes due to their small diameter and insufficient gravity slope when the pipe length is long. This water cannot be completely removed, making it impossible to inspect and repair the pipes, accurately determine pipe quality defects, and pose potential quality risks when robots repair pipes with accumulated water. Therefore, a shallow water pumping device for small-diameter pipes is proposed to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shallow water drainage device for small-diameter pipes. It has the advantages of facilitating pipe inspection or maintenance and effectively improving the cleaning efficiency of small-diameter pipes. It solves the problem that when the pipe laying length is long, the pipe diameter and gravity flow slope are often too small, resulting in shallow water accumulation in the pipe that cannot be cleaned, making pipe inspection and maintenance impossible and making it impossible to accurately judge pipe quality defects.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shallow water pumping device with a small diameter pipe, comprising a pipe, a movable trolley attached to the inner wall of the pipe, a single-phase screw self-priming pump welded inside the movable trolley, an inlet pipe connected to the left side of the single-phase screw self-priming pump, a drain pipe connected to the right side of the single-phase screw self-priming pump, and a movable component provided on the lower side of the movable trolley;

[0006] The moving assembly includes two omnidirectional wheels bolted to the left end of the underside of the moving trolley, two directional wheels bolted to the right end of the underside of the moving trolley, and two side wheels bolted to the side of the moving trolley.

[0007] Furthermore, a pull ring is fixedly connected to the left side of the mobile trolley, and a connecting rope is fixedly sleeved on the inner wall of the pull ring.

[0008] Furthermore, the two omnidirectional wheels are arranged laterally, and the two directional wheels are arranged laterally.

[0009] Furthermore, the side of the lateral wheel away from the moving trolley abuts against the lower side of the inner wall of the pipe.

[0010] Furthermore, the mobile trolley measures 20 cm by 60 cm.

[0011] Furthermore, the suction end of the single-phase screw self-priming pump is connected to the inlet pipe, and the discharge end of the single-phase screw self-priming pump is connected to the drain pipe.

[0012] Furthermore, a second through hole is provided inside the lower side of the mobile trolley, and a first through hole is provided inside the right side of the mobile trolley.

[0013] Furthermore, the inlet pipe passes through the second through hole and extends to its exterior, and the drain pipe passes through the first through hole and extends to its exterior.

[0014] Compared with the prior art, this utility model provides a shallow water pumping device for small-diameter pipes, which has the following beneficial effects:

[0015] 1. This shallow water drainage device for small-diameter pipes uses a connecting rope at one end of the trolley to move the trolley laterally inside the pipe. It works in conjunction with the inlet and outlet pipes on the left side of the single-phase screw self-priming pump to absorb and discharge the water inside the pipe, effectively cleaning the water inside the pipe and improving the cleaning efficiency.

[0016] 2. This small-diameter shallow water drainage device allows for easy movement of the trolley within different curved pipes via casters. The side wheels provide better support for the trolley's sides, preventing tipping and overturning within the pipe. This solves the problem that when laying long pipelines, shallow water often accumulates inside due to insufficient pipe diameter and gravity slope, making it impossible to clean thoroughly, thus hindering pipeline inspection and maintenance, and making it difficult to accurately determine pipeline quality defects.

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1 to 4 This embodiment describes a shallow water drainage device for small-diameter pipes, comprising a pipe 1, a movable trolley 2 attached to the inner wall of the pipe 1, a single-phase screw self-priming pump 3 welded inside the movable trolley 2, an inlet pipe 4 connected to the left side of the single-phase screw self-priming pump 3, and a drain pipe 5 connected to the right side of the single-phase screw self-priming pump 3. A moving assembly is provided on the lower side of the movable trolley 2. The moving assembly includes two universal wheels 9 bolted to the left end of the lower side of the movable trolley 2, two directional wheels 8 bolted to the right end of the lower side of the movable trolley 2, and two side wheels 10 bolted to the side of the movable trolley 2.

[0025] The left side of the mobile trolley 2 is fixedly connected to a pull ring 6, and a connecting rope 7 is fixedly sleeved on the inner wall of the pull ring 6. Two universal wheels 9 are arranged horizontally, two directional wheels 8 are arranged horizontally, and the side wheel 10, away from the mobile trolley 2, abuts against the lower side of the inner wall of the pipe 1. The mobile trolley 2 is 20 cm x 60 cm in size. The suction end of the single-phase screw self-priming pump 3 is connected to the inlet pipe 4, and the discharge end of the single-phase screw self-priming pump 3 is connected to the drain pipe 5.

[0026] It should be noted that pipe 1 has a nominal diameter of 600 mm. The working principle of the single-phase screw self-priming pump 3 is mainly based on the rotation of the screw and the effect of centrifugal force. When the single-phase motor starts, the impeller begins to rotate and generates centrifugal force, drawing liquid into the pump body. At the same time, the screw begins to rotate due to the impeller's drive, creating a space with increased volume. Under the action of the screw, the liquid is gradually drawn into this space and pushed towards the pump body's outlet as the screw rotates. Through this process, a vacuum environment is created inside the pump body, enhancing its self-priming capability. When the liquid is discharged through the pump body's outlet, the entire cycle is complete.

[0027] Meanwhile, the single-phase screw self-priming pump has a diameter of 25 mm, a power of 1.8 kW, and a flow rate of 3 m³ / h.

[0028] Example 2:

[0029] Please see Figures 3 to 4 Based on Embodiment 1, the mobile trolley 2 has a second through hole 12 inside its lower side and a first through hole 11 inside its right side. The water inlet pipe 4 passes through the second through hole 12 and extends to its outside, and the drain pipe 5 passes through the first through hole 11 and extends to its outside.

[0030] By adopting the above technical solution, the water inlet pipe 4 extends to the bottom wall of the pipe 1 through the second through hole 12, which facilitates the absorption of water remaining on the bottom wall of the pipe 1. The first through hole 11 allows the drain pipe 5 to pass through and extend to the outside of the pipe 1, which facilitates the drainage of the absorbed water in conjunction with the water inlet pipe 4.

[0031] The working principle of the above embodiments is as follows:

[0032] Two connecting ropes 7 are fixed to the outside of the pull rings 6 on the side of the mobile trolley 2. The mobile trolley 2 is then pulled from one end of the inspection well to the water accumulation point of the pipe 1 by the connecting ropes 7. During this process, the side wheels 10 abut against the side of the inner wall of the pipe 1 to prevent the mobile trolley 2 from tipping over when it hits the bottom. When there is a certain arc inside the pipe 1, the angle of the mobile trolley 2 can be adjusted by the casters 9. The directional wheels 8 play an auxiliary role in the movement. The water inlet pipe 4 absorbs the water accumulated on the bottom wall of the pipe 1 and discharges it through the drain pipe 5, which facilitates the subsequent inspection or maintenance of the pipe 1 and effectively improves the cleaning efficiency of small-diameter pipes.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
