Description

Technical Field

[0001] This utility model relates to the field of water intake, and in particular to a water intake device and an integrated pumping station. Background Technology

[0002] With the development of urban economies, the demand for industrial wastewater and rainwater discharge is increasing in both rural and urban areas. As a result, the scale and quantity of drainage equipment used in various settings are growing, with integrated pump stations being one such example. An integrated pump station includes a cylinder, inlet and outlet pipes mounted on the cylinder, and a pump housed within the cylinder.

[0003] To mitigate the impact of water flow on the inlet pipe or the cylinder, existing integrated pump stations typically incorporate baffles or other components within the cylinder corresponding to the inlet pipe. This not only complicates the overall structure and increases installation difficulty but also raises manufacturing costs. Furthermore, large particles and debris in the sewage can clog the inlet pipe or pump as they flow into the cylinder, increasing the maintenance rate and shortening the lifespan of the integrated pump station.

[0019] Implementing this utility model has the following beneficial effects:

Several buffer holes are provided on the side wall of the second pipe section within the pump body. These buffer holes are arranged along the axial and circumferential directions of the inlet pipe, reducing the impact of water flow on the inlet pipe and pump body, thus protecting the inlet pipe and internal pump components and extending the service life of the integrated pump station.

[0022] Figure 2 yes Figure 1 Enlarged view of point A. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] See Figure 1-2 This utility model discloses a water inlet device, including a water inlet pipe 1. The water inlet pipe 1 has an inlet 13 and an outlet 14. The water inlet pipe 1 includes a first pipe section and a second pipe section that are connected. The inlet 13 is located on the first pipe section, and the outlet 14 is located on the second pipe section. The included angle between the first pipe section and the second pipe section is 90 degrees.

[0025] The second pipe section has several buffer holes 11 on its side wall, and the buffer holes 11 are arranged along the axial and circumferential directions of the water inlet pipe 1; the second pipe section has a buffer plate 12, which is located between the buffer holes 11 and the water outlet 14.

[0026] This utility model's water inlet device includes an inlet pipe, which comprises a first pipe section and a second pipe section connected together. Several buffer holes are provided on the side wall of the second pipe section within the pump body. These buffer holes are arranged along the axial and circumferential directions of the inlet pipe, reducing the impact of water flow on the inlet pipe and pump body, thus protecting the inlet pipe and internal pump components and extending the service life of the integrated pump station. Simultaneously, a buffer plate is also provided within the second pipe section, positioned between the buffer holes and the outlet, i.e., below the buffer holes, further buffering the water flow. The device features a simple structure, easy installation, and low manufacturing cost.

[0027] Preferably, the buffer plate 12 is provided with a plurality of filter holes (not shown in the figure), and the buffer plate 12 extends obliquely from the buffer holes 11 toward the outlet 14. Specifically, one end of the buffer plate 12 is fixedly connected to the inner wall of the inlet pipe 1, and the other end is a free end. The buffer plate can further play a buffering role to reduce the potential energy of water flowing into the pump body, thereby protecting the internal components of the pump body and extending the service life of the integrated pump station. At the same time, the buffer plate plays a certain filtering role through the filter holes, filtering out some impurities and reducing the amount of impurities in the sewage entering the pump body.

[0028] Furthermore, such as Figure 1-2As shown, this utility model also includes a crushing mechanism, which includes a drive mechanism 5 and a crushing component connected to the drive mechanism 5. The crushing component is located inside the second pipe section and below the buffer plate 12. Preferably, the crushing component is located at the outlet 14. The drive mechanism 5 is a drive motor, which drives the crushing component to rotate, thereby intercepting and crushing large particles and garbage in the sewage, preventing blockage of the inlet pipe or water pump, reducing the maintenance rate of the integrated pump station, and extending its service life.

[0029] Specifically, such as Figure 1-2 As shown, the crushing assembly includes a rotating shaft 3 and a crushing scraper 2 mounted on the rotating shaft 3. The crushing scraper 2 is placed inside a second pipe section, and the rotating shaft 3 extends out of the second pipe section and is connected to a drive mechanism 5. That is, one end of the rotating shaft 3 extends into the second pipe section and is connected to the crushing scraper 2, while the other end extends out of the second pipe section and is connected to the drive mechanism 5. The drive mechanism drives the rotating shaft to rotate, which in turn drives the crushing scraper to rotate, thereby crushing large particles of impurities and waste.

[0030] Preferably, such as Figure 1-2 As shown, a worm gear 4 is mounted on the rotating shaft 3, and a worm 7 is mounted on the output shaft 6 of the drive mechanism 5. The worm gear 4 and the worm 7 are connected to drive the crushing scraper 2. The drive mechanism drives the worm to rotate via the output shaft, which in turn drives the worm gear to rotate. The worm gear then drives the rotating shaft to rotate, thereby causing the crushing scraper to rotate within the second pipe section, acting on large particles of impurities and debris to crush them and prevent blockage. The worm gear is fixed to the other end of the rotating shaft, but is fixed relative to the circumference of the rotating shaft. The screw is fixed to the free end of the output shaft, and is also fixed relative to the circumference of the output shaft.

[0031] More preferably, the output shaft 6 and the worm gear 7 are integrally formed; the rotating shaft 3 and the worm wheel 4 are integrally formed. This structure is simple, has few parts, and is low in cost.

[0032] Furthermore, such as Figure 1-2 As shown, the crushing mechanism also includes a control mechanism (not shown) and a pressure sensor 8. The pressure sensor 8 is mounted on the buffer plate 12, and the control mechanism is connected to both the pressure sensor 8 and the drive mechanism 5. The pressure sensor 8, mounted on the buffer plate 12, can detect the water pressure flowing across the buffer plate. When the water pressure reaches or exceeds a preset value, the pressure sensor sends a signal to the control mechanism, which then controls the drive mechanism to start, causing the crushing scraper to rotate and act on the water flow, crushing large particles and debris in the water flow to prevent clogging of the inlet pipe or water pump. When the water pressure drops to the preset value, the pressure sensor interrupts the signal, and the control mechanism controls the drive mechanism to shut down, stopping the crushing scraper from rotating.

[0033] Preferably, the crushing mechanism further includes an alarm mechanism (not shown) connected to the control mechanism. When the pressure sensor sends a signal to the control mechanism, the control mechanism simultaneously activates the alarm mechanism, informing the user that the crushing component is working and that there may be a blockage, thus alerting the user.

[0034] Accordingly, see Figure 1-2 This utility model also discloses an integrated pump station, including a pump body 100 and the aforementioned water inlet device. The pump body 100 has a cavity 101. A first pipe section passes through the wall of the pump body 100. The water inlet 13 is located outside the cavity 101, the second pipe section is placed inside the cavity 101, and the water outlet 14 is placed inside the cavity 101. Specifically, the water outlet 14 is located above the bottom of the cavity 101. The specific structure of the water inlet device is as described above and will not be repeated here. Sewage flows into the inlet pipe through the inlet and then into the cavity through the outlet. The multiple buffer holes can reduce the impact of the water flow on the inlet pipe and the pump body; the buffer plate further reduces the potential energy of the water flow. Its structure is simple and low-cost.

[0035] Preferably, such as Figure 1 As shown, a mounting platform 102 is provided inside the cavity 101, and the mounting platform 102 is located above the water inlet pipe 1. The drive mechanism 5 is located on the mounting platform 102. The output shaft 6 of the drive mechanism 5 extends downward from the mounting platform 102 and is connected to the rotating shaft 3 to drive the crushing scraper 2 to rotate inside the water inlet pipe 1, thereby crushing large particles of impurities and garbage.

[0036] Preferably, such as Figure 1 As shown, the pump body 100 has an inspection port 103 on its top for easy maintenance by the user.

[0037] In summary, this utility model provides a water inlet device and an integrated pump station that reduces the impact force of water flow, has a simple structure, and is low in cost.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
