[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Broad Application Prospects: This utility model's pipeline flow velocity detection equipment can be widely used in pipeline flow velocity measurement in fields such as petroleum, chemical, water conservancy, and environmental protection. Especially in applications requiring long-term stable operation and high-precision measurement, this equipment has significant technical advantages and application value. This utility model's pipeline flow velocity detection equipment not only improves the accuracy and reliability of flow velocity measurement but also reduces maintenance costs and operational difficulty through intelligent impurity removal functions and convenient maintenance design. This equipment represents a significant technological advancement and has broad application prospects in various pipeline flow velocity measurement applications.

[0027] This utility model relates to a pipeline flow velocity detection device, the overall structure of which is as follows: Figures 1 to 4 As shown, it mainly includes key components such as the detection housing 1, rotating shaft 2, propeller blade 3, flow velocity detector 4, and impurity removal mechanism 5.

[0028] The detection housing 1, as the main body of the entire equipment, has sufficient strength and sealing to accommodate and protect key components such as the internal rotating shaft 2 and propeller blades 3. A flow velocity detector 4 is fixedly installed on the upper surface of the detection housing 1 to measure and display the flow velocity of the fluid in the pipeline in real time.

[0029] The rotating shaft 2 is rotatably mounted on the inner bottom wall of the detection housing 1, and several propeller blades 3 are fixedly mounted on its surface. The propeller blades 3 are evenly distributed in a ring array on the surface of the rotating shaft 2, and each propeller blade 3 is fixedly connected at a 30-degree angle. This design optimizes the hydrodynamic effect, enabling the rotating shaft 2 to rotate more smoothly and efficiently under the propulsion of the fluid.

[0030] The flow velocity detector 4 is fixedly mounted on the upper surface of the detection housing 1 and is fixedly connected to the top end of the rotating shaft 2. When the rotating shaft 2 rotates, the flow velocity detector 4 can accurately measure its rotation speed and convert it into the flow velocity value of the fluid in the pipe for display and recording.

[0031] It is worth noting that the impurity removal mechanism 5 is a major highlight of this utility model, and its structure is as follows: Figure 3 and Figure 4 As shown, it mainly includes components such as a cleaning cylinder 501, a filter screen 502, a guide impeller 503, a movable shaft 504, a moving frame 505, a cleaning rod 506, and a cleaning brush 507.

[0032] It should be noted that the impurity removal cylinder 501 is installed on the right side of the detection housing 1, and a filter screen 502 is fixedly installed inside it. The filter screen 502 can block most impurities from entering the interior of the detection housing 1, thereby protecting critical components such as the propeller blades 3 and the rotating shaft 2 from damage. The filter screen 502 has a conical structure, which helps to better guide the fluid through and filter impurities.

[0033] It should be noted that the guide impeller 503 is rotatably mounted on the inner wall of the impurity removal cylinder 501, and a movable shaft 504 is fixedly mounted on its left end. When fluid passes through the impurity removal cylinder 501, it drives the guide impeller 503 to rotate. The movable shaft 504 rotates along with the guide impeller 503, and drives the cleaning rod 506 and cleaning brush 507 to move on the surface of the filter screen 502 via the movable frame 505. This design achieves an automatic cleaning function for the filter screen 502, effectively preventing the filter screen 502 from clogging.

[0034] It should be noted that the cleaning rods 506 are symmetrically distributed on both sides of the filter screen 502, and cleaning brushes 507 are fixedly installed on their surfaces. The cleaning brushes 507 overlap with the surface of the filter screen 502 and continuously brush the surface of the filter screen 502 as the guide impeller 503 rotates. This design ensures the continuous cleanliness and unobstructed flow of the filter screen 502.

[0035] To further facilitate cleaning and maintenance, this invention includes a drain outlet at the bottom of the impurity removal cylinder 501, and a sludge collection box 508 is installed on the inner wall of the drain outlet. The sludge collection box 508 is fixed to the bottom of the impurity removal cylinder 501 by a positioning mounting block 509 and fixing bolts 510, and is used to collect and process the filtered impurities. When impurities accumulate in the sludge collection box 508 to a certain extent, it can be easily disassembled for cleaning and replacement.

[0036] It is worth noting that the pipeline flow velocity detection device of this utility model also has high flexibility and convenience in terms of installation and connection.

[0037] It should be noted that the combined use of the threaded retaining sleeve 6 and the limiting mounting ring 7 allows the impurity removal cylinder 501 to be easily threaded onto the surface of the detection housing 1. This design not only improves the overall stability of the equipment but also facilitates the disassembly and replacement of the impurity removal cylinder 501, thereby simplifying the equipment maintenance process.

[0038] The placement of the first connecting pipe 8 and the first flange 9, as well as the second connecting pipe 10 and the second flange 11, provides a standard flange connection method for the equipment. This design allows the equipment to be quickly connected and disconnected from the piping system, improving its applicability and flexibility. Simultaneously, the flange connection method also provides excellent sealing performance, ensuring the normal operation of the equipment under harsh conditions such as high pressure and high temperature.

[0039] Working principle and operation procedure: When the pipeline flow velocity detection device of this utility model is working, the fluid enters the impurity removal cylinder 501 through the first pair of connecting pipes 8. After being filtered by the filter screen 502, the pure fluid enters the detection housing 1 through the liquid inlet. Driven by the fluid, the propeller blades 3 drive the rotating shaft 2 to rotate, thereby driving the flow velocity detector 4 to measure and display the flow velocity.

[0040] When impurities in the fluid accumulate to a certain level, they are blocked by the filter screen 502 and deposited inside the impurity removal cylinder 501. At this time, the guide impeller 503 rotates under the drive of the fluid, driving the cleaning rod 506 and cleaning brush 507 through the movable shaft 504 to automatically clean the filter screen 502. The cleaned impurities enter the sludge collection box 508 through the drain port. After accumulating to a certain level, they are cleaned and replaced. To ensure the long-term stable operation and measurement accuracy of the equipment, users need to perform regular maintenance and inspection. The specific operating procedure includes: disassembling the sludge collection box 508 for cleaning and replacement; and checking the cleanliness and wear of the filter screen 502.

[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
