[0030] The measuring assembly includes a measuring instrument body 4 disposed on the outer wall of the pipe body; the measuring instrument body is connected to a probe 6;

[0031] The probe is connected to the support assembly installed inside the pipe body and is used for measuring air volume and wind speed inside the pipe.

[0032] In the above technical solution, by setting up a pipe assembly, a measuring assembly, and a supporting assembly, the pipe assembly includes a pipe body and a first through hole and a second through hole disposed in the pipe body; the measuring assembly includes a measuring instrument body disposed on the outer wall of the pipe body; the measuring instrument body is connected to a probe; the probe is connected to the supporting assembly disposed in the pipe body for measuring air volume and wind speed in the pipe; this solves the problems of cumbersome operation of fixing the probe inside the pipe and inaccurate data due to the limitation to single-point measurement in the prior art.

[0033] Specifically, the beneficial effects of the aforementioned pipeline air volume and velocity measuring device for thermal control in thermal power plants include:

[0034] Simplify probe mounting procedure:

[0035] Structural optimization: By incorporating a support assembly, the probe can be directly connected to the support assembly within the pipe body, avoiding complex fixing operations inside the pipe. This design simplifies probe installation and removal, reducing maintenance time and labor costs.

[0036] Ease of operation: Compared with existing technologies, this measuring device eliminates the need for cumbersome fixing procedures inside the pipe; the probe can be installed simply by making a connection outside the pipe. This greatly improves work efficiency and reduces operational difficulty.

[0037] Improve measurement accuracy:

[0038] Multi-point measurement capability: By setting a first through hole and a second through hole (and possibly more through holes as needed) on the duct body, and in conjunction with corresponding measuring components, this device can achieve multi-point measurement of air volume and velocity within the duct. Multi-point measurement can more comprehensively reflect the air volume and velocity distribution within the duct, thereby improving measurement accuracy.

[0039] Reduced measurement errors: Existing technologies may lead to measurement errors due to uneven distribution of airflow and velocity within the duct during single-point measurement. This new measuring device, however, uses multi-point measurements to more accurately capture changes in airflow and velocity within the duct, thus reducing measurement errors.

[0040] Enhance device adaptability and reliability:

[0041] Adaptable to different pipe sizes: The design of the pipe assembly allows the measuring device to adapt to pipes of various sizes.

[0043] Easy to maintain and upgrade:

[0044] Modular Design: This measuring device adopts a modular design, allowing for independent maintenance and upgrades of the measuring components, support components, and piping components. When a component fails or requires an upgrade, only the corresponding component needs to be replaced, without the need for large-scale modifications to the entire device.

[0045] Reduced maintenance costs: The modular design also reduces maintenance costs. Because components can be replaced independently, spare parts inventory and repair time are reduced. This also improves the maintainability and scalability of the unit.

[0046] In one possible implementation, the support assembly includes a slide bar 7, wherein,

[0047] The probe is slidably connected to the slide rod.

[0048] Specifically, the beneficial effects include: the sliding connection between the probe and the slide bar allows for flexible adjustment of the probe's position within the pipeline, meeting the needs of different measurement points, enabling multi-point precise measurements, and improving data accuracy. Furthermore, the sliding connection facilitates flexible movement and positioning of the probe within the pipeline, making operation convenient and adaptable to complex pipeline environments. When a specific area requires focused monitoring, the probe can be quickly moved to the corresponding position, improving measurement efficiency and flexibility.

[0049] In one possible implementation, the slide bar is connected to the inner wall of the pipe body.

[0050] Specifically, the beneficial effects include: the connection between the slide rod and the inner wall of the pipe body provides stable support for the probe, ensuring a stable probe position during measurement, reducing measurement errors caused by shaking, and improving data accuracy. At the same time, this connection method makes the structure more compact and reasonable, without occupying excessive pipe space or affecting airflow within the pipe. Furthermore, it is easy to install, facilitates subsequent maintenance, allows for quick disassembly for inspection or replacement of components, and ensures long-term stable operation of the measuring device.

[0051] In one possible implementation, the support assembly includes a power unit, wherein,

[0052] The power unit is used to drive the probe.

[0053] Specifically, the beneficial effects include: the power unit drives the probe, enabling automatic probe movement without manual operation, saving manpower and increasing efficiency. The probe can be flexibly moved within the duct according to a preset program, achieving accurate measurements at multiple points and locations, obtaining more comprehensive airflow and velocity data, and improving measurement accuracy. It can also adapt to different measurement needs, quickly adjusting the probe position, enhancing the flexibility and practicality of the device, and ensuring smooth measurement operations.

[0054] In one specific implementation scheme, the power unit is a push rod motor 8.

[0055] Specifically, the beneficial effects include: precise control over the probe's movement distance and speed, ensuring accurate measurement positioning and improving measurement accuracy. The smooth operation of the push rod motor reduces vibration and swaying during probe movement, avoiding interference with measurements. Furthermore, its compact structure and small footprint facilitate installation inside pipelines, enabling automated control, easy operation, and improved measurement efficiency.

[0056] In one possible implementation, the power unit is fixedly connected to the slide bar.

[0057] Specifically, the beneficial effects include: the fixed connection between the power unit and the slide bar ensures strong structural stability, guarantees stable power transmission, and allows the probe to move smoothly on the slide bar, improving measurement accuracy. The fixed connection also facilitates overall installation and maintenance, reducing the risk of component loosening. Simultaneously, the power unit can drive the slide bar more directly and efficiently, allowing the probe to quickly and accurately reach the designated position, improving measurement efficiency and ensuring the smooth progress of measurement work.

[0058] In one possible implementation, the probe is connected to the end of the power output shaft of the push rod motor.

[0059] Specifically, the beneficial effects include: precise power transmission, enabling the push rod motor to efficiently drive the probe movement, accurate position control, and improved measurement accuracy; a simple and straightforward structure, reducing transmission components, lowering the probability of failure, and ensuring stable operation of the device; and ease of installation and commissioning, allowing the probe to quickly enter working condition and facilitating subsequent maintenance and replacement, thereby improving measurement efficiency and meeting the needs of pipeline airflow and velocity measurement.

[0060] In one possible implementation, the measuring instrument body and the probe are connected by a wire 5.

[0061] Specifically, the beneficial effects include: the wire connection can stably transmit the signals collected by the probe, ensuring that the data is accurately and promptly transmitted to the measuring instrument, reducing signal loss or interference, and improving measurement accuracy. Moreover, the connection is simple and direct, with low cost and convenient installation and maintenance. At the same time, the wire has a certain degree of flexibility, which can adapt to the movement of the probe inside the pipe without affecting its normal operation, providing a reliable signal transmission guarantee for airflow and wind speed measurement.

[0062] In one possible implementation, the measuring instrument body is wirelessly connected to the probe.

[0063] Specifically, the benefits include: wireless connectivity eliminates the constraints of wires, allowing probes to move more flexibly within pipes, unrestricted by line length and routing, reaching more measurement points and improving measurement comprehensiveness. Installation eliminates the need for wiring, simplifying the process and reducing costs. Furthermore, reduced interference from wires ensures stable signal transmission, improving the accuracy and reliability of measurement data, making measurement work more efficient and convenient.

[0064] In one possible implementation, the pipe body is made of stainless steel.

[0065] Specifically, the beneficial effects include: strong corrosion resistance, enabling long-term use in humid and chemical-containing environments, thus extending pipeline lifespan; high strength, capable of withstanding significant pressure, ensuring pipeline structural stability; smooth surface, resistant to dust and scale accumulation, reducing interference with internal measuring probes and other components, facilitating accurate measurements; and aesthetically pleasing appearance, easy to clean and maintain, meeting the performance and appearance requirements of various scenarios.

[0066] Specifically, the installation process of the pipeline air volume and velocity measuring device for thermal control in thermal power plants is as follows:

[0067] Pipe assembly preparation: Ensure that the pipe body is installed in place according to the design requirements, and that the positions of the first and second through holes are accurate so that the probe of the measuring assembly can pass through smoothly.

[0068] Measurement Component Installation: Install the measuring instrument body in a suitable location on the outside of the pipe body, ensuring it is securely installed and will not shake due to airflow or other factors within the pipe. Connect one end of the lead wire to the measuring instrument body and the other end to the probe. During the connection process, ensure a secure connection to avoid problems such as poor contact. Insert the probe into the pipe body through the first or second through hole, adjusting the initial position of the probe according to the actual measurement requirements.

[0069] Support assembly installation: Install the slide bar inside the pipe body, ensuring it can slide freely. The installation position of the slide bar should match the probe's movement trajectory to stably support the probe. Connect the probe to the slider, allowing the slider to slide on the slide bar, thereby moving the probe inside the pipe.

[0070] The above technical solution is easy to operate: it changes the cumbersome operation method of fixing the probe inside the pipeline by welding or drilling, making the installation process more convenient; it is accurate in measurement: it can detect the wind speed at different parts of the pipeline, avoiding the data deviation caused by single-point measurement, and making the measurement results more accurately reflect the actual situation inside the pipeline.
