Description

Technical Field

[0001] This utility model relates to the field of pipeline descaling technology, specifically to an integrated vehicle-mounted intelligent water and air pressure regulating device for pipeline descaling. Background Technology

[0002] In modern municipal and building management, pipes need to be cleaned regularly to avoid blockage or damage. Currently, pipe cleaning mainly relies on high-pressure water guns. To facilitate the operation, integrated pipe cleaning vehicles have emerged, which integrate various systems of cleaning equipment for convenient operation.

[0003] Existing pipe cleaning equipment is mostly water-air mixed jet device, which relies on the high-pressure cleaning effect of the gas-liquid mixed jet to flush the dirt attached to the pipe. However, the continuous high-pressure impact is not as effective as variable frequency jet or pulse jet in cleaning. If the gas-water pressure needs to be adjusted, the pump needs to be controlled to achieve frequency conversion, which is very cumbersome. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides an implementation scheme: Existing pipe cleaning equipment is mostly a water-air mixed jet device, which relies on the high-pressure cleaning effect of the gas-liquid mixed jet to flush the dirt attached to the pipe. However, the continuous high-pressure impact is not as effective as frequency conversion jet or pulse jet in cleaning. If the steam and water pressure needs to be adjusted, the pump needs to be controlled to achieve frequency conversion, which is very cumbersome.

[0021] According to the instruction manual Figure 1-3 As can be seen, in order to solve the above-mentioned technical problems, this application discloses an integrated vehicle intelligent water and air pressure regulating device for pipe descaling, including a storage tank 1, a jet pump 2 connected to one side of the storage tank 1, a water supply pipe 3 connected to one side of the jet pump 2, and a jet mixing device 4 provided on one side of the water supply pipe 3.

[0022] According to the instruction manual Figure 1-3 It is known that the above-mentioned jet mixing device 4 includes a mixing pipe 41 as a gas-liquid mixing channel. The end flange of the water supply pipe 3 is connected to the inlet of the mixing pipe 41. The side wall of the mixing pipe 41 is connected to the air intake mixer 42. The mixer includes a tube 421 and a small compressor 422 for drawing air to form a basic gas-liquid jet. The outlet of the pipe is connected to a water spray hose 43 and a handheld spray gun with integrated wireless control function. The gas-liquid jet is introduced into the handheld spray gun through the water spray hose 43. The cleaning personnel hold the handheld spray gun and spray water onto the pipe to be cleaned.

[0023] According to the instruction manual Figure 1-3 It can be seen that the core pulse controller 45 of the jet mixing device 4 consists of a frequency converter 46, a commutation ring 461, an annular plate 462, and a through-hole plate 464: the output shaft of the frequency converter 46 drives the commutation ring 461 to rotate, the annular plate 462 is fixedly connected inside the commutation ring 461, and the annular plate 462 is provided with multiple through holes 463 arranged in an annular array; the end of the mixing pipe 41 is equipped with a through-hole plate 464, the plate surface is provided with a triple concentric annular hole array, the annular plate 462 and the through-hole plate 464 are parallel to each other with a gap of 0.5mm; the rotating shaft extending from the center of the through-hole plate 464 is assembled at the center of the annular plate 462 via an angular contact bearing to ensure high-speed rotation coaxiality accuracy.

[0024] According to the instruction manual Figure 1-3It can be seen that when the frequency converter 46 drives the ring plate 462 to rotate, the fan-shaped hole and the annular hole periodically overlap and misalign, converting the steady-state jet into an adjustable pressure pulse of 5-20Hz, with the peak pressure reaching 1.8 times the steady-state value, and efficiently removing the fouling from the pipe wall through the transient water hammer effect.

[0025] An annular sealing plate 465 extends into the mixing pipe 41 through the orifice plate 464. Its edge is fitted with a fluororubber sealing strip and fits against the inner wall of the pipe. When the sealing plate 465 rotates synchronously with the orifice plate 464, it intermittently blocks the inlet of the insertion tube 421. When the sealing plate 465 completely blocks the insertion tube 421, the airflow is interrupted and a pure water impact phase is formed. When it is removed, the air and water flow are sprayed synchronously to generate a transient pressure difference. This alternating impact creates a tearing effect on stubborn oil stains, thereby improving the cleaning efficiency. The inner wall of the mixing pipe 41 is coated with a tungsten carbide coating to resist cavitation wear and extend its service life by 3 times. The edge of the through hole 463 is rounded to reduce fluid noise by 12dB.

[0026] As a preferred option, the storage tank 1 is a rectangular box with a water outlet on one side of the bottom that is connected to the jet pump 2. The top of the storage tank 1 has a water inlet with a sealing plate 465 connected to it. The water inlet on the top of the storage tank 1 can be used to replenish water, and the water outlet on the storage tank 1 is used to drain the water.

[0027] As a preferred option, the perforated plate 464 is further provided with a number of through holes arranged in a concentric ring, with a dense outer and sparse inner layout to optimize the uniformity of the jet.

[0028] As a preferred option, a rotating shaft extends from one side of the center of the perforated plate 464 and is mounted on the center of the ring plate 462, with bearing support ensuring the stability of the rotational speed at 2000 rpm.

[0029] As a preferred embodiment, the intake mixer 42 further includes a tube 421. The tube 421 is connected to one side of the mixing pipe 41. A small compressor 422 is connected to the tube 421. The small compressor 422 performs air compression to inject high-pressure air into the tube 421, and then the high-pressure air is introduced into the cleaning water through the tube 421.

[0030] As a preferred option, a further step is to extend a sealing plate 465 from one side of the orifice plate 464, which is coaxial with the mixing pipe 41 and fits the inner wall of the mixing pipe 41. The sealing plate 465 intermittently seals the opening of the insertion tube 421, and the fluororubber sealing plate 465 achieves intermittent blockage of the gas path.

[0031] In summary, this integrated vehicle-mounted intelligent water and air pressure regulating device for pipeline descaling utilizes a mechanical rotating pulse generator. The ring plate 462 and the through-hole plate 464 are positioned opposite each other to generate adjustable pressure pulses from 5-20Hz. The peak pressure reaches 1.8 times the steady-state value, inducing a water hammer effect to efficiently remove dirt. The intermittent shielding of the air path by the linkage sealing plate 465 ensures strict synchronization of water and air shock waves. The transient pressure difference generates a tearing effect on the grease, improving cleaning efficiency. The tungsten carbide coating and noise reduction design enhance the device's durability, while wireless control avoids complex electronic control systems.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
