[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel, and is often used in pipeline operations.
[0003] Most traditional flow meters operate in a temperature range of -20 to 55°C. Normal operation is guaranteed only within this range. Once the ambient temperature is not suitable, especially in summer, most existing flow meters are exposed to the sun, which can easily cause the flow meter to operate in an ambient temperature that is too high, affecting the measurement accuracy and causing damage to the internal components of the flow meter. In response to the above problems, the inventors have designed a high-temperature resistant pipeline flow meter. Summary of the Invention

DETAILED DESCRIPTION
[0020] See also Figure 1-4, the utility model provides the following technical solutions:
[0021] Specifically, it refers to a high-temperature resistant pipeline flow meter, including a measuring tube 1 and a detection instrument 2 installed on the measuring tube 1. The outer surface of the measuring tube 1 is provided with a storage box 3 for storing cooling water, and the outer surface of the detection instrument 2 is provided with a wrapping shell 4. The inner side of the wrapping shell 4 close to the detection instrument 2 is made of pure copper, so the heat generated inside the detection instrument 2 is more easily conducted to the wrapping shell 4. The upper surface of the front side of the wrapping shell 4 is provided with an output pipe 6 connected to the interior thereof, and the other end of the output pipe 6 is connected to the lower surface of the storage box 3. A water pump 8 for conveying cooling water to the output pipe 6 is provided on the bottom wall of the storage box 3. The lower surface of the rear side of the wrapping shell 4 is provided with an input pipe 5 connected to the interior thereof, and the other end of the input pipe 5 The end is connected to the upper surface of the storage box 3 and is connected to the interior thereof. When in use, it is started by the water pump 8, and the cooling water in the storage box 3 is extracted to the output pipe 6. The cooling water is transported to the enclosing shell 4 through the output pipe 6, and after flowing in the enclosing shell 4, it is finally re-input into the storage box 3 through the input pipe 5. Therefore, the flowing cooling water can take away the heat generated by the operation of the detection instrument 2, thereby achieving the purpose of cooling the detection instrument 2, and at the same time, it also isolates the influence of the external high temperature on the detection instrument 2, thereby improving the high temperature resistance of the flow meter, and avoiding the problem of damage to the components inside the flow meter caused by the flow meter running in a high temperature environment for a long time, thereby ensuring the accuracy of the flow meter in measuring pipeline flow.
[0022] A cooling plate 7 for cooling the cooling water is provided in the storage box 3. The cooling plate 7 is an existing known technology and will not be described in detail here. When the cooling water that absorbs heat flows into the storage box 3, the cooling water is cooled again by the cooling plate 7, thereby ensuring a long-term cooling effect on the detection instrument 2.
[0023] The output pipe 6 includes an inner tube 61 and a thermal insulation cotton sleeve 62 wrapped around the outer surface of the inner tube 61. The thermal insulation cotton sleeve 62 isolates the influence of the external high temperature environment on the cooling water inside the output pipe 6, further ensuring the cooling effect on the detection instrument 2. At the same time, the storage box 3 and the outer surface of the wrapping shell 4 are also provided with a thermal insulation cotton sleeve 62, further improving the cooling effect on the flow meter.
[0024] The left side of the storage box 3 is provided with a drawer 9 that slides through the interior thereof. The drawer 9 is located on one side of the storage box 3 in a mouth-shaped shape and is located directly below the input pipe 5. A filter screen 10 for filtering cooling water is provided in the drawer 9. When in use, the cooling water input into the storage box 3 through the input pipe 5 falls onto the filter screen 10, while the solid impurities in the cooling water are blocked by the filter screen 10 and cannot fall into the storage box 3. This further ensures the cleanliness of the cooling water in the storage box 3 and improves the heat absorption effect of the cooling water on the flow meter.
[0025] The outer surface of the drawer 9 is provided with a rubber pad for increasing the sealing performance, which reduces the problem of cold air in the storage box 3 escaping through the storage box 3.
[0026] A limiting slide bar 14 is provided between the left and right inner walls of the drawer 9, and a connecting slide sleeve 15 is provided on the outer surface of the limiting slide bar 14. A scraper 16 for scraping the surface of the filter screen 10 is provided on the lower surface of the connecting slide sleeve 15. When in use, the connecting slide sleeve 15 slides back and forth on the limiting slide bar 14, so that the scraper 16 can scrape off the solid impurities attached to the filter screen 10, thereby avoiding the problem of the filter screen 10 being blocked by too many impurities directly below the inlet pipe 5 as much as possible, and further ensuring the filtering effect of the filter screen 10 on the cooling water.
[0027] A rotating shaft 11 is rotatably connected to the inner wall of the drawer 9, and a fan blade 12 is sleeved on the outer surface of the rotating shaft 11. The right blade of the fan blade 12 is located directly below the input pipe 5. When cooling water flows into the storage box 3 through the input pipe 5, the water flow will form a thrust on the fan blade 12, so that the fan blade 12 synchronously drives the rotating shaft 11 to rotate.
[0028] A disc 13 is provided at the front end of the rotating shaft 11, and a sleeve shaft 17 is provided on the front side of the disc 13. The sleeve shaft 17 is provided on the side away from the center of the disc 13. A rotating plate 18 is rotatably sleeved on the outer surface of the sleeve shaft 17. The other side of the rotating plate 18 is hinged to the connecting sleeve 15. When the rotating shaft 11 rotates, the disc 13 rotates synchronously with the rotating shaft 11, thereby driving the sleeve shaft 17 to perform eccentric movement. In this way, the sleeve shaft 17 will form a pulling force or a pushing force on the rotating plate 18, so the rotating plate 18 synchronously pulls or pushes the connecting sleeve 15 to slide back and forth on the limiting slide rod 14. The above simple structure is adopted to achieve the conversion of natural resources and the purpose of driving the connecting sleeve 15 to slide back and forth. No additional electric components are required, which further guarantees the environmental significance and environmental value of the device.
[0029] The working principle of the high-temperature resistant pipeline flow meter provided by the present invention is as follows: it is started by the water pump 8, and the cooling water in the storage box 3 is extracted to the output pipe 6. The cooling water is transported to the wrapped shell 4 through the output pipe 6, and after flowing in the wrapped shell 4, it is finally re-input into the storage box 3 through the input pipe 5. Therefore, the flowing cooling water can take away the heat generated by the operation of the detection instrument 2, thereby achieving the purpose of cooling the detection instrument 2.
