Description

Technical Field

[0002] Utility model patent CN221493453U discloses a variable frequency cleaning and unclogging machine. The machine's water pipes are connected to the outlet of a high-pressure pump. The vehicle body includes pipe supports, a bottom connecting pipe, and a top connecting pipe. Two pipe supports are arranged side-by-side. Each pipe support includes an outer sleeve, an inner sliding rod slidably connected inside the outer sleeve, and a limiting member positioned between the outer sleeve and the inner sliding rod. The bottom connecting pipe is located below the two pipe supports and is fixedly connected to the two outer sleeves. The top connecting pipe is located between the two inner sliding rods and is fixedly connected to the two inner sliding rods. This cleaning and unclogging machine can only be equipped with one hose reel, making it impossible to select hose reels with different flow rates according to different unclogging and cleaning operations. Its applicability is narrow. Furthermore, the high-pressure pump driver lacks cooling and heat dissipation functions, which can easily lead to overheating of the high-pressure pump during prolonged cleaning and unclogging operations. Additionally, some cleaning water remains inside the high-pressure pump after cleaning and unclogging operations, which can easily cause corrosion if left unused for a long time, affecting its service life.

Detailed Implementation

[0023] Example 1, see appendix Figure 1-2 A vehicle-mounted new energy pipeline dredging and cleaning machine includes a water tank 1, a high-pressure pump set, and water spray hose reels 4 mounted on a frame. At least two water spray hose reels 4 are provided, with different hose sizes and different water flow rates for the spraying operation. The inlet of the high-pressure pump set is connected to the water tank 1 via an inlet pipe 34, and the outlet is connected to a main water supply pipe 31. A high-pressure distribution valve 32 is connected to the end of the main water supply pipe. The high-pressure distribution valve 32 and each water spray hose reel 4 are connected via several water supply... Water branch pipe 33 is connected, and the end of the water spray hose reel 4 is provided with a rotary joint 8. The water supply branch pipe 33 is connected to the rotary joint 8. A water supply hose reel 2 is provided on the frame. A water supply pipe 21 is connected between the water tank 1 and the rotary joint 8 at one end of the water supply hose reel 2. The hose is released by unwinding the water supply hose reel 2. The hose is used to connect to the water source. A water pump connected to the water supply pipe 21 is provided inside the water tank 1. When the water pump is started, water from the water source can be drawn into the water tank 1 through the water supply pipe 21 and the hose.

[0024] The high-pressure pump set includes a high-pressure water pump 3 and a permanent magnet synchronous motor 6. The output shaft of the permanent magnet synchronous motor is connected to the input shaft of the high-pressure water pump 3, and the permanent magnet synchronous motor 6 drives the high-pressure water pump 3 to run.

[0025] The upper part of the high-pressure water pump 3 is equipped with a pressure regulating valve 91, which is connected to the water tank 1 through a return pipe 92.

[0026] The bottom of the frame is provided with a receiving cavity, which contains a high-voltage battery pack 71 and a low-voltage storage battery 72. The combination of the high-voltage battery pack and the low-voltage storage battery provides power to the permanent magnet synchronous motor 6 and the air compressor 5.

[0027] A geared motor 41 is installed on the bracket of the water spray hose reel 4. The geared motor automatically drives the water spray hose reel to wind up and unwind the hose. The geared motor 41 is a worm gear motor with a self-locking function. After winding up and unwinding, the water spray hose reel 4 can be locked.

[0028] When the cleaning machine in this embodiment is working, the permanent magnet synchronous motor 6 is started to drive the high-pressure water pump 3 to run. The high-pressure water pump pumps the water in the water tank 1 into the main water supply pipe 31 through the water inlet pipe 34. Different water supply branch pipes 33 can be connected to the main water supply pipe 31 through the high-pressure distribution valve 32. Each water spray hose reel 4 can be connected to the high-pressure water pump 3. The appropriate flow rate of the water spray hose reel is selected according to the cleaning operation conditions on site. The reduction motor 41 of the water spray hose reel 4 is started to unwind the hose and pull the water spray hose to carry out the cleaning operation.

[0029] Example 2, see appendix Figure 3-4 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a pneumatic drainage device connected to the high-pressure pump set is provided inside the frame. The pneumatic drainage device includes an air compressor 5 and a three-way valve 53. The three-way valve 53 is an electromagnetically controlled three-way valve. A high-pressure air pipe 52 is connected to the outlet of the air compressor 5. The three-way valve 53 is installed at the inlet of the high-pressure pump set. The water inlet pipe 34 and the high-pressure air pipe 52 are respectively connected to the connector of the three-way valve 53. The end of the high-pressure air pipe 52 is equipped with a solenoid valve 51 connected to the air compressor 5. After the cleaning and unblocking operation is completed, the water inlet pipe 34 of the high-pressure pump set is closed by the three-way valve 53 and the high-pressure air pipe 52 is opened. High-pressure gas enters the high-pressure water pump from the high-pressure air pipe, blowing out the residual cleaning water. This avoids the phenomenon of rust inside the pump body caused by long-term storage and can effectively improve its service life.

[0030] Example 3, see appendix Figure 3-4This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: a circulating cooling device for the permanent magnet synchronous motor 6 is provided inside the frame. The circulating cooling device includes a liquid-cooled water tank 61 and a circulating water pump 62. The circulating water pump 62 is fixed on the frame by a support. The permanent magnet synchronous motor 6 is provided with a water circulation inlet and a water circulation outlet. Both the water circulation inlet and the water circulation outlet are connected to the cooling chamber inside the housing of the permanent magnet synchronous motor 6. The water circulation inlet and the liquid-cooled water tank 61 are connected by an inlet water circulation pipe 63, and the water circulation outlet and the liquid-cooled water tank 61 are connected by an outlet water circulation pipe 64. The circulating water pump 62 is installed on the inlet water circulation pipe 63, and a high-pressure controller 65 is installed on the outlet water circulation pipe 64. The high-pressure controller automatically controls the circulating water pump 62 according to the flow rate and temperature of the cooling water, so that the water cooling temperature and the operating power of the permanent magnet synchronous motor 6 are matched, thereby enabling it to operate stably in the optimal temperature range.

[0031] The working process of this embodiment is as follows: the circulating water pump 62 is started to draw cooling water from the liquid cooling water tank 61 into the inlet circulation pipe 63, and then from the inlet circulation pipe 63 into the cooling chamber of the permanent magnet synchronous motor 6 housing. Then, the water flows out from the outlet circulation pipe 64 back to the liquid cooling water tank 61, thereby realizing the water cooling circulation cooling of the permanent magnet synchronous motor 6 housing, ensuring that it is in a stable operating temperature range and avoiding the phenomenon of excessively high stable temperature.

[0032] An expansion tank 66 is mounted on the frame, and the expansion tank is connected to the upper part of the liquid cooling water tank 61 through an expansion tube 67.

[0033] The high-pressure water pump 3 is connected to a pressure gauge 54 via a pipeline. The pressure gauge is located in the middle of the front end of the frame. The pressure value of the high-pressure water pump 3 can be easily viewed through this pressure gauge to avoid excessive pressure.
