Description

Technical Field

[0001] This invention relates to a pipeline silt reduction device. Background Technology

[0002] With rapid urbanization, the conflict between urban sewage collection and treatment has become increasingly prominent. Currently, urban sewage treatment is divided into two pipelines: surface collection and deep transport. Sewage flows through shallow pipelines to collection stations for preliminary treatment before being transported to sewage treatment plants via underground pipelines. Shallow pipelines for surface sewage to collection stations offer numerous and convenient cleaning methods; however, deep sewage transport pipelines are difficult to clean, present significant challenges and risks, and lack efficient and convenient cleaning measures. Safe, efficient, and reliable equipment is needed to solve the problem of cleaning deep sewage transport pipelines. Summary of the Invention

[0003] Purpose of the invention: In view of the above-mentioned prior art, a shuttle-shaped silt reduction device for sewage conveying pipes is proposed, which can reduce silt in deeply buried sewage conveying pipes, reduce the dredging cycle of deeply buried sewage conveying pipes, and extend the service life of the pipes.

[0004] Technical Solution: A shuttle-shaped silt reduction device for sewage conveying pipes includes a shuttle-shaped outer shell with an opening at the top and a top cover with a water inlet at the opening. Two sets of jet propulsion outlets are symmetrically arranged about the longitudinal section of the outer shell at the bottom. A reverse propulsion jet outlet is also located below the head of the outer shell. Several miniature circulating high-pressure pumps are fixed inside the outer shell, and the outlets of each miniature circulating high-pressure pump are connected to the jet propulsion outlets and the reverse propulsion jet outlets via pipelines. The jet directions of the two symmetrical jet propulsion outlets are V-shaped and facing the rear of the device. The inlets of each miniature circulating high-pressure pump are connected to the water inlet. A power supply is also fixed inside the outer shell, and the power supply is connected to each miniature circulating high-pressure pump via a control device.

[0005] Furthermore, the outer shell satisfies the following irregular hyperellipse equation in its longitudinal vertical section:

[0006]

[0007] In the formula, a is the half length of the major axis of the superellipse, and b is the half length of the minor axis of the superellipse; the outer shell is circular in the transverse cross-section.

[0008] Furthermore, the outer casing is also equipped with a video monitoring device, which is connected to the control device.

[0009] Furthermore, the control device includes a wireless communication module.

[0010] Beneficial Effects: The shuttle-shaped silt reduction device for sewage conveying pipes of this invention can reduce silt in deeply buried sewage conveying pipes, shorten the dredging cycle of these pipes, and extend their service life. The device uses a shuttle-shaped outer shell, which reduces water resistance, saves kinetic energy, and improves endurance. The figure-eight-shaped jet propulsion outlet ensures propulsion and heading, preventing yaw. Two sets of jet propulsion outlets on both sides are controlled by two miniature circulating high-pressure pumps, and a reverse propulsion jet outlet is also provided at the head, improving the device's maneuverability. Furthermore, this device can be remotely controlled and its silt reduction status can be monitored in real time via video during operation. Attached Figure Description

[0015] The invention will now be further explained with reference to the accompanying drawings.

[0016] A shuttle-shaped silt reduction device for sewage conveying pipes, such as Figure 1 As shown, it includes a spindle-shaped outer shell 1, with an opening 2 at the top of the outer shell 1, and a device such as... Figure 2 The top cover 3 shown has a water inlet hole 4, and the top cover 3 has a good seal after being installed with the opening 2. Figure 3 , Figure 4 As shown, the lower part of the outer casing 1 has two sets of jet propulsion outlets 5, totaling six jet propulsion outlets 5, arranged symmetrically in pairs about the longitudinal vertical section of the outer casing 1; a reverse propulsion jet outlet 6 is also provided below the head of the outer casing 1. Inside the outer casing 1 is a device mounting bracket 8, on which three miniature circulating high-pressure pumps (not shown) are fixed. The outlet of one miniature circulating high-pressure pump is connected to the three jet propulsion outlets 5 on one side via a pipeline, and the outlet of another miniature circulating high-pressure pump is connected to the three jet propulsion outlets 5 on the other side via a pipeline. The jet directions of the two symmetrical jet propulsion outlets 5 are V-shaped and facing the rear of the device. The outlet of the third miniature circulating high-pressure pump is connected to the reverse propulsion jet outlet 6 via a pipeline. The inlets of each miniature circulating high-pressure pump are connected to the inlet holes 4 on the top cover 3 via pipelines, and each inlet hole 4 is equipped with a sediment filter screen.

[0017] In addition, a video monitoring device 7 is installed at the rear of the outer casing 1. A power supply and a control device are also fixed on the equipment mounting bracket 8. The power supply provides power and signal transmission to each miniature circulating high-pressure pump and the video monitoring device 7 through the control device. The control device contains a wireless communication module for receiving wireless control signals and uploading video monitoring data. The layout of the internal structures must ensure the overall balance of the device in water.

[0018] Working principle of this invention: This device is used to reduce siltation in deep sewage pipelines within cities. The device incorporates a high-pressure circulating pump, power source, and control module, and includes a real-time video monitoring module. The high-pressure circulating pump inlet is located on the top cover of the device to minimize the entry of large particles of silt. Two sets of jet propulsion outlets at the bottom are each connected to a miniature circulating high-pressure pump. While propelling the device, the jets effectively disturb the silt, increasing the hydrodynamic force within the pipeline and allowing the silt to flow downstream with the water, reducing siltation. The figure-eight shaped jet propulsion outlets ensure the device's propulsion direction. In addition, a separate reverse propulsion jet outlet is located at the head of the device to improve its maneuverability. From a maintenance and ease-of-use perspective, the device includes a built-in remote control system for convenient operation, and a video monitoring system is installed at the rear for direct monitoring of underwater conditions and immediate evaluation of the siltation reduction effect.

[0019] Considering the special environment inside the pipeline, in order to prevent the equipment from being entangled by debris and to reduce water flow resistance, the device is designed in a spindle shape. Specifically, the outer shell 1 satisfies the following irregular hyperellipse equation on the longitudinal vertical section:

[0020]

[0021] In the formula, 'a' represents the semi-length of the major axis of the hyperellipse, and 'b' represents the semi-length of the minor axis of the hyperellipse; the outer shell 1 is circular in the transverse cross-section. The specific values ​​of parameters 'a' and 'b' represent the overall external dimensions of the device, which can be set according to the actual application scenario. A spindle-shaped outer shell is fabricated based on this irregular hyperellipse equation, utilizing its continuous, smooth, and integral characteristics to reduce water flow resistance.

[0022] In addition, this shuttle-shaped silt reduction device for sewage conveying pipes can be used not only for silt reduction in deep sewage conveying pipelines in cities, but also for silt reduction in similar projects such as the lower culverts of overpasses and inverted siphons.

[0023] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
