Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning devices, in particular to an automatic inspection device for cleaning a fluid system. Background Art

[0002] Many shared equipment projects, such as ventilation and air conditioning, water supply and drainage, heating, dust removal, and chemical plant exhaust, require corresponding distribution or heat exchange systems to meet the overall fluid system's requirements for distribution and heat and mass exchange. During fluid system operation, scaling, dust accumulation, and even leaks often occur in the pipe network after a period of operation due to various reasons. Manual inspections are often difficult and costly to troubleshoot.

[0003] Scaling and dust accumulation in fluid systems can affect the system's normal operation, causing a significant gap between actual operating values and original design values. This can lead to system disruption and prevent the system from achieving the required temperature, pressure, and other parameters. This can also increase the system's operating energy consumption and, over time, shorten the system's service life. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic inspection device for cleaning a fluid system, so as to predict scaling, dust accumulation, leakage and the like of a conventional fluid system in advance, reduce the probability of system failure, extend the practical life of the equipment, improve the system operation efficiency, save the system operation cost, etc.

[0005] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: an automatic inspection device for cleaning a fluid system, comprising a main line, the main line is provided with a main line valve, the main line is provided with a plurality of parallel branch lines, each of the branch lines is provided with a stop valve, a pressure gauge and a terminal device; a bypass pipe is provided on the main line, the two interfaces of the bypass pipe and the main line are located on both sides of the main line valve, the interface position of the bypass pipe and the main line is provided with a stop valve, the bypass pipe is provided with a constant flow device, and the constant flow device is located between the two stop valves; and a data processing device is also included, and the signal output ends of the constant flow device and the pressure gauge communicate with the data processing device through wired or wireless means for electrical signals.

[0006] Preferably, each branch pipeline is provided with a pressure gauge, and the pressure gauge is provided between the stop valve and the terminal device.

[0007] Preferably, each branch pipeline is provided with two pressure gauges, wherein one of the pressure gauges is provided between the stop valve and the terminal device, and the other pressure gauge is provided on the other side of the terminal device.

[0008] Preferably, the data processing device feeds back a signal to the signal input terminal of the main valve in a wired or wireless manner.

[0009] The beneficial effects of the utility model are as follows: the pipe network system operates normally at ordinary times and periodically enters a self-test state; when entering the self-test state, the main pipe access is cut off, the branch pipe is opened, and the flow rate is fixed or monitored by a constant flow device. In the self-test state, by monitoring the flow rate, pressure and other parameters in a specific area, the parameters are transmitted to the processor, and the processor gives a corresponding judgment result to determine whether the system needs cleaning or maintenance. This device can be used for scaling and leakage monitoring of fluid systems such as water supply and drainage, heating, etc., and can also be used for dust accumulation and cleaning monitoring of dust removal systems.
