DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] Please refer to Figures 1-7The application provides a technical scheme: a pipeline sound attenuation equipment for a gas pressure regulating device based on an Internet of Things, which comprises a front gas converging assembly 1 and a rear gas converging assembly 2, and together they constitute a core part of a gas conveying system. A plurality of first conveying pipes 3 are arranged between the front gas converging assembly 1 and the rear gas converging assembly 2. The specifications of each first conveying pipe 3 are different, such as the diameter, length or material difference. Based on actual requirements such as flow size or pressure requirements, different specifications of the first conveying pipe 3 can be selected to convey gas, so as to realize flexible configuration. A gas inlet 11 is arranged on the side wall of the front gas converging assembly 1, and the gas inlet 11 is used for conveying gas to the inside of the front gas converging assembly 1 efficiently, serving as an inlet point of the system. The gas is stably conveyed to the rear gas converging assembly 2 through the first conveying pipe 3, and the gas conveying process is completed, so as to ensure seamless transmission of the gas between the assemblies. A pipeline sound attenuation structure is arranged on the conveying path of the first conveying pipe 3. The structure comprises a sound attenuation outer bin 12, and the side walls of the sound attenuation outer bin 12 are symmetrically provided with side sound attenuation bins 39 on both sides. The sound attenuation outer bin 12 and the side sound attenuation bin 39 both adopt a sound absorption layer of foamed aluminum, and the porosity reaches 60%-85% and the pore diameter is 0.2-1.5 mm. The high-porosity porous structure can effectively absorb and attenuate high-frequency turbulent flow noise, and the noise reduction is realized through multiple reflections and energy dissipation of sound waves in the pores. The structure can achieve the first layer sound attenuation purpose and significantly improve the quietness during the operation of the system. A group of gas pump assemblies is independently arranged in each sound attenuation outer bin 12. The purpose of the gas pump assembly is to provide continuous kinetic energy for the pumping of the gas, maintain the stability and efficiency of the gas conveying, and prevent pressure fluctuation. The gas pump assembly comprises a front end fixed shell 13, the outer side of the front end fixed shell 13 is fixed on the inner wall of the side sound attenuation bin 39 through a connecting piece, and the gas cannot pass through, a filter screen 18 is arranged on the surface of the front end fixed shell 13, and is used for filtering impurities in the gas to ensure clean conveying, a gas pump 14 is installed on one side of the front end fixed shell 13, the gas pump 14 is a low-noise main pump, and the gas pump 14 comprises an outer shell 15 and an existing technology structure pump arranged in the inner shell. The part protruding from the front end fixed shell 13 of the outer shell 15 is disc-shaped, a plurality of first through holes 16 are arranged on the disc-shaped surface, intelligent valves are arranged on the inner sides of the first through holes 16, the intelligent valves are controlled by a remote system, and the opening and closing operation is realized through a sensor and an instruction, and each intelligent valve can independently operate to realize accurate adjustment. The gas enters the front end fixed shell 13 through the filter screen 18, enters the gas pump 14 through the front end fixed shell 13, is pumped out after being pressurized in the gas pump 14, and the power of the gas pump 14 can be remotely controlled to adapt to different working condition requirements.When the power of the gas pump 14 is remotely controlled to increase, the rate of gas passing through the filter screen 18 increases accordingly, and the pressure on the filter screen 18 is significantly increased. Long-time high-pressure gas delivery is easy to cause the filter screen 18 to be damaged and deformed or blocked. At this time, the control system monitors and drives the intelligent valve to open in real time when the gas pump 14 is in a high-power state, thereby adding an auxiliary channel for gas delivery and shunting part of the gas flow, thereby reducing the pressure on the filter screen 18 and protecting the integrity of the filter screen 18. In addition, if the gas is only passed through the filter screen 18 when the gas pump 14 is in a high-power state for a long time, the turbulent flow at the filter screen 18 will be intensified, and the noise level will increase. By reducing the amount of gas passing through the filter screen 18, the opening of the intelligent valve effectively achieves the function of noise reduction and optimizes the overall system performance.

[0026] The gas pump assembly further comprises a rear end fixed housing 19 which is fixedly connected with the outer housing 15 by welding or bolts, thereby forming a highly sealed space between the rear end fixed housing 19 and the outer housing 15, which is mainly used to accommodate internal moving parts and prevent gas leakage. A chuck 20 is stably installed in the inner cavity of the rear end fixed housing 19. The disc surface of the chuck 20 is made of wear-resistant material, and a first sliding rod 21, a second sliding rod 22 and a third sliding rod 23 are vertically arranged on the surface of the chuck 20. These sliding rods are all made by precise machining process and penetrate the disc surface of the chuck 20, and the contact surface between the sliding rods and the chuck 20 is sealed by rubber or metal sealing rings to ensure that there is no leakage when the gas flows. A driving member 24 is installed between the first sliding rod 21, the second sliding rod 22 and the third sliding rod 23. The driving member 24 is usually an electric or pneumatic actuator, and the internal output end thereof is fixedly connected with a front sealing disc 25 through a rigid connecting member. The contour size and geometric shape of the sealing disc 25 are accurately matched with those of the chuck 20, and a convex and concave groove design is adopted to enable the sealing disc 25 and the chuck 20 to be tightly engaged or smoothly separated, so as to control the opening and closing of the gas passage.

[0027] A plurality of second through holes 26 are uniformly distributed on the disc surface of the chuck 20. These second through holes 26 are designed in a normally open mode to allow the gas to continuously pass through in a low-power state and maintain the basic delivery efficiency. When the gas pump 14 starts to enter a high-power mode, the control system drives the driving member 24 to operate through an electrical signal. The output end of the driving member 24 pushes the sealing disc 25 forward, so that the sealing disc 25 gradually separates from the initial engagement state, thereby exposing the third through holes 27 in the middle region of the chuck 20 which were originally covered by the sealing disc 25. The third through holes 27 have a large aperture and are uniformly distributed along the stepped surface of the chuck 20, forming a multi-stage passage and significantly increasing the gas flow cross-sectional area and the delivery capacity. At the same time, this stepped design can disperse the gas pressure and effectively reduce the noise generated by high-speed airflow through the pressure reduction effect.

[0028] In addition, the bottom of the gas pump 14 housing is provided with a clamping hole 28, which is usually recessed, and the support rod 29 is fixedly installed on the surface of the sealing disc 25, which is made of light alloy material, and the end thereof is connected to the clamping rod 30 by hinging or welding, and the clamping rod 30 is accurately matched with the clamping hole 28 in shape. When the gas pump 14 is in a high-power state, the body thereof will vibrate strongly due to high-speed operation, at which time the control system synchronously drives the driving member 24 to operate, the driving member 24 drives the sealing disc 25 to move, the displacement of the sealing disc 25 is transmitted to the clamping rod 30 through the support rod 29, the clamping rod 30 is quickly inserted into the clamping hole 28, mechanical locking is formed, the vibration amplitude of the gas pump 14 is limited, and thus the vibration noise is greatly reduced.

[0029] The structure of the clamping rod 30 is optimized and designed, the part thereof in contact with the clamping hole 28 is a complete hollow cylinder, an internal cavity is formed to reduce the weight, and the remaining part is a bare solid cylinder, the combined structure can significantly reduce the operating load of the driving member 24 and avoid overload damage; at the same time, the hollow part can provide an additional gas bypass channel after being inserted into the clamping hole 28, increase the gas delivery path, further improve the system efficiency and assist in noise reduction.

[0030] The rear side of the chuck 20 is provided with a threaded pipe 31 extending out of the rear end fixing shell 19, and a three-way valve 32 is arranged on the part of the threaded pipe 31 outside the rear end fixing shell 19. The three-way valve 32 includes three interfaces respectively connected with the threaded pipe 31, the sound attenuation outer bin 12 and the main output end of the gas pump assembly. The three-way valve 32 is used to deliver the gas in the gas pump assembly to the sound attenuation outer bin 12 through the threaded pipe 31, so as to realize the direct communication between the sound attenuation outer bin 12 and the gas pump assembly. The functions of the three-way valve 32 are as follows: first, timely pressure relief of the gas pump assembly is realized to avoid damage of the equipment caused by excessive internal pressure; second, the detection sensor arranged in the sound attenuation outer bin 12 is used to monitor the gas composition in real time, so as to ensure the purity and safety of the gas; and third, the external pump machine is used to realize the gas extraction process of the gas pump assembly through the three-way valve 32, so as to improve the maintenance efficiency. The sixth conduit 33 is arranged on the side wall of each sound attenuation outer bin 12, and all the sixth conduits 33 are connected with each other through an annular pipeline to form a closed gas circulation network, so that all the sound attenuation outer bins 12 can realize free intercommunication and pressure balance of the gas. The intelligent pump machine 34 is arranged on each sixth conduit 33, and the intelligent pump machine 34 is provided with a flow sensor and an automatic regulating valve. The intelligent pump machine 34 is used to accurately control the gas into and out of the sound attenuation outer bin 12, and dynamically adjust the flow rate and pressure according to the system requirement. Since the gas amount required to be delivered by each first conveying pipe 3 is inconsistent, when the gas amount delivered by a certain first conveying pipe 3 suddenly increases at a certain time, the intelligent pump machine 34 responsively increases the gas inlet or outlet rate of the corresponding sound attenuation outer bin 12, so as to maintain the flow balance and stable operation of the overall system. When the gas pump 14 operates at high power, if the internal pressure exceeds the preset threshold value, high-frequency impact noise will be generated by the turbulent flow of high-speed gas in the pipeline. The three-way valve 32 is used to direct the gas into the sound attenuation outer bin 12 through pressure relief, so as to attenuate the noise by using the acoustic structure of the sound attenuation outer bin, and avoid the vibration noise of the pump body caused by pressure fluctuation.

[0031] Inside the rear end fixed shell 19 of the device, a high-performance air pump machine 35 is assembled, the inlet 36 of the air pump machine adopts a straight-through design through the rear wall of the rear end fixed shell 19, which ensures that its gas inlet is directly exposed to the external environment, so that it can efficiently suck in the gas medium, and the outlet 37 of the air pump machine 35 is precisely positioned at a specific position of its side wall. This layout optimizes the gas discharge path, ensuring that the pressurized gas can be directed and smoothly output. Under this driving, the air pump machine 35 continuously and powerfully sucks gas from the inlet 36, and completes the pressure boosting process in its internal pressure boosting chamber, finally reliably discharges the gas flow that has been stably pressurized from the lateral outlet 37. The core goal of this core working mechanism is to form a precise counter-flow field with the main gas flow direction in the main pipeline, effectively offsetting the irregular fluctuations of the main gas flow pressure, and promoting the significant reduction of gas flow velocity in the terminal area of the high-speed conveying pipeline. This active speed reduction avoids the continuous high-speed flow of gas in the entire subsequent conveying process. It is particularly important to note that in the entire gas conveying system, only the structural unit where the gas pump 14 is located is specially configured with a composite noise reduction structure (such as sound-absorbing materials or shock-absorbing design), and the rest of the pipelines and related connecting structures in the system are not provided with any noise reduction measures. Therefore, when the gas runs at high speed in these pipelines without noise reduction treatment, it inevitably produces significant fluid dynamics noise and mechanical vibration noise.

[0032] The top of each first conveying pipe 3 is firmly provided with a first conduit 4, which is usually designed to be pressure-resistant to ensure the sealing and efficiency of gas flow. All first conduits 4 are uniformly gathered and connected to a second conduit 5 through flange connection, forming a preliminary gas gathering and conveying network. The second conduit 5 is provided with a third conduit 6 at one end region, which is directly connected to the front gas gathering assembly 1 for receiving the initial gas source. At the same region, a fifth conduit 10 is provided, which is firmly connected to the rear gas gathering assembly 2 as an interface for backup or increased conveying path. The other end region of the second conduit 5 is tightly connected to a fourth conduit 7 through welding, and the end of the fourth conduit 7 is equipped with a gas conveying end 38, which adopts a multi-branch design to efficiently convey gas to various required structures such as boilers or heating equipment through flexible joints, ensuring uniform and stable gas distribution. In addition, the side wall of the fourth conduit 7 is connected to a second conveying pipe 8 through a valve, one end of the second conveying pipe 8 is firmly connected to the rear gas gathering assembly 2, and the other end is directly connected to a centrally located storage bin 9, which is provided with a buffer device for temporarily storing gas and adjusting flow fluctuations.

[0033] In the standard operation mode, the control system monitors the gas flow in real time, drives the gas to be stably delivered from the front gas assembly 1 to the second conduit 5 through the first delivery pipe 3, and then efficiently delivered to the fourth conduit 7 through the guidance of the second conduit 5, and finally accurately output to the target structure through the gas delivery end 38, ensuring the continuity and reliability of the delivery process. When the gas delivery amount significantly increases or the delivery path needs to be expanded, the control system automatically switches modes, driving the gas to be preferentially delivered to the rear gas assembly 2, and then quickly delivered to the middle storage bin 9 through the booster pump of the second delivery pipe 8; the storage bin is provided with a flow regulating valve, allowing the gas to flow back to the fourth conduit 7 directly from the outlet of the second delivery pipe 8 or the middle storage bin 9, and finally output through the gas delivery end 38. This multi-path design not only enhances the flexibility of the system, but also effectively disperses mechanical vibrations through the optimization of pipeline layout and the application of shock absorber supports, making the operation of the entire gas delivery pump station more stable and reliable, significantly reducing the noise generated by high-frequency vibration, and improving the comfort of the operating environment.
