Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind speed transmitter technology, specifically to an anti-clogging wind speed transmitter device based on multi-parameter measurement. Background Technology
[0002] An anemometer is a sensor device used to measure the speed of airflow. It converts the physical quantity of wind speed into a measurable and transmissible electrical signal, which is usually a standard current or voltage signal. This facilitates further processing and analysis in control systems, data acquisition systems, or monitoring systems. Anemometers are widely used in the industrial field to detect the speed and direction of fluids. They can also be used in meteorology, oceanography, environment, agriculture, forestry, water conservancy, power, and scientific research.
[0003] Existing hot-wire anemometers are based on the principle of heat transfer. They estimate wind speed by measuring the cooling rate of the heating element (such as a hot wire or hot film) in the wind. The faster the wind speed, the higher the cooling rate, which changes the electrical signal output. However, existing hot-wire anemometers have certain drawbacks. The gas flow velocity in the middle of the pipe differs from that near the pipe wall, which can affect the measured temperature. Utility Model Content

[0008] Optionally, the detector body includes a display screen, a connector, and wires, and the probe is electrically connected to the body via the wires and connector.
[0009] Optionally, a measuring hole is provided at the center of the outer side of the probe housing, and a measuring block is fixedly installed inside the measuring hole.

[0012] Optionally, two circular mounting grooves are provided at both ends of the measuring hole on the housing. The inner diameter of the mounting groove is equal to the inner diameter of the bearing, and the bearing is fixedly installed inside the mounting groove.
[0013] This invention provides an anti-clogging wind speed transmitter device based on multi-parameter measurement, which has the following advantages:
[0014] 1. This anti-clogging wind speed transmitter device based on multi-parameter measurement allows the lead screw to extend and retract relative to the housing by rotating the knobs at both ends of the housing. This changes the length of the probe, adapting it to pipes of different diameters. Furthermore, the extension and retraction adjustment of the lead screw can position the measuring hole and the measuring block in the middle of the measuring tube, ensuring that the measurement position is always in the middle of the measuring tube, eliminating the influence of this variable on the measurement results and improving the accuracy of the measurement.

[0023] 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.
[0024] Example
[0025] Please see Figures 1 to 2 The present invention provides a technical solution including a measuring tube 1 and a detector 2. The detector 2 also includes a main body 3 and an adjustable probe 4. The probe 4 includes a housing 401. Rotating knobs 402 are rotatably installed at both ends of the housing 401. Lead screws 403 are slidably installed at both ends of the housing 401. The rotating knobs 402 are threadedly connected to the lead screws 403. Rubber pads 404 are provided at the ends of the two lead screws 403 outside the housing 401. A dustproof plate 5 is fixedly installed on the outside of the probe 4. A cleaning component 6 is rotatably installed on the outside of the probe 4.
[0026] Specifically, the adjustable probe 4 can be positioned at the center of the measuring tube 1 after adjustment, ensuring that the measurement position is the same each time and eliminating the influence of this variable on the measurement results. The cleaning component 6 can clean the probe 4, effectively preventing the wind speed transmitter from becoming clogged.
[0027] Please refer to Figure 2. The main body 3 of the detector 2 includes a display screen 301, a connector 302 and a wire 303. The probe 4 is electrically connected to the main body 3 through the wire 303 and the connector 302. The display screen 301 is equipped with a processor to collect the data collected by the probe 4 and control the operation of the transmitter.
[0028] Specifically, the display screen 301 is connected to the measuring block 406 on the probe 4 via the wire 303 and connector 302, so that the staff can know the wind speed measurement situation inside the measuring tube 1 from the outside.
[0029] Please refer to Figure 2 to Figure 5A measuring hole 405 is provided at the center of the outer side of the outer shell 401 of the probe 4. A measuring block 406 is fixedly installed inside the measuring hole 405. The measuring block 406 is composed of a heating wire and a temperature sensor. The heating wire is a thin metal wire that is heated by electricity. The temperature sensor is responsible for monitoring the temperature change of the heating wire and calculating the wind speed by the cooling rate of the heating wire in the wind.
[0030] Specifically, by rotating the knob 402, the extension and retraction of the lead screw 403 can be adjusted, so that the measuring block 406 on the outer shell 401 of the probe 4 is located at the center of the measuring tube 1. This not only allows the probe 4 to be adapted to measuring tubes of different diameters, but also eliminates errors caused by different measuring positions.
[0031] Please refer to Figure 3 to Figure 4 The size of the dustproof plate 5 is adapted to the size of the inner side of the measuring hole 405. The dustproof plate 5 is fixedly installed in the measuring hole 405 of the probe 4. The dustproof plate 5 is set on the top of the measuring hole 405. The outer arc surface of the dustproof plate 5 is flush with the arc outer side of the outer shell 401.
[0032] Specifically, the dustproof plate 5 can be used to prevent dust in the wind from covering the measuring block 406.
[0033] Please see Figures 3 to 6 The cleaning assembly 6 includes two bearings 601, and three sails 602 are fixedly installed on the outside of the two bearings 601. The three sails 602 are evenly distributed on the outside of the bearings 601 with the axis of the bearings 601 as the center. A cleaning brush 603 is provided between the two sails 602 and is fixedly installed on the outside of the two bearings 601.
[0034] Two circular mounting grooves are provided at both ends of the measuring hole 405 on the housing 401. The inner diameter of the mounting groove is equal to the inner diameter of the bearing 601. The bearing 601 is fixedly installed inside the mounting groove. The outer diameter of the bearing 601 is larger than the outer inner diameter of the mounting groove.
[0035] Specifically, the wind power is used to rotate the sailboard 602, which in turn drives the cleaning brush 603 on the bearing 601 to rotate. The dust on the surface of the dustproof plate 5 is cleaned by the rotation of the cleaning brush 603.
[0036] In use, probe 4 is installed inside measuring tube 1. It is connected to connector 302 on display screen 301 and measuring block 406 inside probe 4 via wire 303, thus connecting probe 4 inside measuring tube 1 to external display screen 301. Measuring block 406 on probe 4 monitors the wind speed inside measuring tube 1. A temperature sensor inside measuring block 406 monitors the temperature of the heating wire. The data of the temperature change of the heating wire in the wind, measured by the temperature sensor, is transmitted to the display screen 301 of the main body 3 of external detector 2 via wire 303. The display screen 301 shows the cooling rate of the heating wire inside measuring tube 1 in the wind, thereby calculating the wind speed inside measuring tube 1. Based on the inner diameter of measuring tube 1, the rotation knob 402 on the outer shell 401 of probe 4 is rotated. The rotation knob 402 is threadedly connected to lead screw 403, causing lead screw 403 to extend and... The probe 4 is contracted to adjust the distance between its two ends to be equal to the inner diameter of the pipe, allowing the probe 4 to be locked inside the pipe. When adjusting the length of the probe 4, the length of both ends of the probe 4 can be slightly larger than the inner diameter of the pipe, thereby squeezing the rubber pad 404 at the end of the lead screw 403, increasing the friction between the probe 4 and the inner wall of the measuring tube 1, so that the probe 4 can be locked inside the pipe. By rotating the knob 402 to adjust the lead screw 403, the measuring hole 405 and the measuring block 406 can be positioned in the middle of the measuring tube 1, ensuring that the measurement position is always in the middle of the measuring tube 1, eliminating the influence of this variable on the measurement results, and improving the accuracy of the measurement. During measurement, the direction of airflow in the pipe blows the sail 602 to drive the bearing 601 to rotate, thereby causing the cleaning brush 603 on the bearing 601 to clean the dustproof plate 5 on the outside of the measuring block 406, preventing dust blockage and affecting the measurement results.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
