Description

Technical Field

[0001] This utility model relates to the field of wind speed transmitter technology, specifically to an anti-clogging device for wind speed transmitters. Background Technology

[0002] The anti-clogging device of the wind speed transmitter is used to solve the problem that the sampling device is easily blocked by dust when measuring the wind pressure or differential pressure of gas containing dust. It can ensure the continuous and normal operation of the instrument and is conducive to safe production.

However, such structures require more pipes, and the manufacturing cost is high because they require a controller. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an anti-clogging device for an anemometer, comprising a measuring instrument 1, a high-pressure pipe 2 fixedly connected to the lower part of the measuring instrument 1, a low-pressure pipe 3 fixedly connected to one side of the high-pressure pipe 2, the low-pressure pipe 3 having the same shape and dimensions as the high-pressure pipe 2, a protective shell 5 detachably connected to the outer surface of the low-pressure pipe 3, a mating shell 6 detachably installed on one side of the protective shell 5, threads provided at the lower end of the mating shell 6 and the lower end of the protective shell 5, a fixed bushing 8 threadedly connected to the outer surface of the mating shell 6, and a fixed bushing 8 fixedly connected to the lower part of the fixed bushing 8. There is a screw-on sleeve 9, and a sealing gasket 10 is fixedly connected to the lower part of the screw-on sleeve 9. A connector 11 is fixedly connected to the lower part of the sealing gasket 10. A connecting pipe port 601 is opened on one side of the upper end of the mating shell 6. A connecting pipe 12 is installed inside the connecting pipe port 601. A reversing valve 14 is fixedly connected to the other end of the connecting pipe 12. A pressurizing pipe 15 is fixedly connected to one end of the reversing valve 14. An air pump 16 is fixedly connected to the other end of the pressurizing pipe 15. The air pump 16 is fixedly connected to the back of the measuring instrument 1. An air inlet pipe 17 is fixedly connected to the front and top of the air pump 16.

[0025] Specifically, the fixed bushing 8 allows for quick assembly and disassembly of the device, facilitating maintenance and installation. The air pump 16 and pressurized pipe 15 pressurize the high-pressure pipe 2 and low-pressure pipe 3, thereby expelling foreign objects from the air inlets of the high-pressure pipe 2 and low-pressure pipe 3 through the pressure difference.

[0026] Please see Figures 1 to 3The measuring instrument 1 is a model applicable to all measuring instruments with corresponding pipe interfaces. The upper end of the low-pressure pipe 3 and the upper end of the high-pressure pipe 2 are provided with pipe interfaces 4. The upper end of the high-pressure pipe 2 and the upper end of the low-pressure pipe 3 are respectively connected to the corresponding interfaces of the measuring instrument 1 through the pipe interfaces 4. The shape and size of the mating shell 6 correspond to the shape and size of the protective shell 5. A baffle 7 is fixedly connected to the upper end of the outer surface of the mating shell 6. The maximum diameter of the baffle 7 is larger than the inner diameter of the fixed bushing 8. There are several baffles 7, and the several baffles 7 are evenly distributed in a symmetrical manner on the upper end of the outer surface of the mating shell 6 and the corresponding positions of the protective shell 5.

[0027] Specifically, the anti-clogging device of the wind speed transmitter, through the setting of the baffle 7, enables the anti-clogging device of the wind speed transmitter to limit the fixed bushing 8 through the baffle 7, making the device more stable. Through the cooperation of the protective shell 5 and the fixed bushing 8, the protective shell 5 and the mating shell 6 can be quickly assembled and disassembled through the fixed bushing 8 during use, thereby achieving the purpose of quick assembly and disassembly of the fixed device, making installation and maintenance convenient and quick.

[0028] Please see Figures 4 to 5 There are several connecting pipes 12, which are evenly distributed on one side of the upper end of the high-pressure pipe 2 and at the corresponding position of the low-pressure pipe 3. The connecting pipe 12 is equipped with a one-way valve 13, which is for the flow direction to the high-pressure pipe 2 and the low-pressure pipe 3.

[0029] Specifically, by setting up the one-way valve 13, the anti-clogging device of the wind speed transmitter can prevent air from passing through the one-way valve 13 during the measurement of data, thereby preventing any impact on the data. Through the cooperation of the air pump 16 and the pressurization pipeline 15, air can be drawn in by the air pump 16 during use, and pressurized through the pipeline passage connected to the pressurization pipeline 15 and the reversing valve 14. When the internal pressure of the blocked section of the pipeline is too high, foreign objects can be pushed out, thereby clearing foreign objects and preventing blockage by pressurizing the blocked section of the pipeline. This achieves the purpose of simple structure and low manufacturing cost because no controller installation is required.

[0030] In use, first connect the measuring instrument 1 through the pipe interface 4, then mate the mating shell 6 with the protective shell 5, and connect and fix the fixed bushing 8 by screwing the screwing sleeve 9. After fixing, insert the high-pressure pipe 2 and the low-pressure pipe 3 through the connection port of the pipe to be tested, and then screw the connector 11 to the pipe to be tested, so that the sealing gasket 10 fits tightly with the pipe to be tested. After fixing, the assembly and installation of the device are complete. When in use, when the air in the pipe to be tested passes through, high pressure will be formed in the high-pressure pipe 2 at the windward side, and low pressure will be formed in the low-pressure pipe 3 at the leeward side. The accurate value of the wind speed can be obtained through the measuring instrument 1. During use, pipe blockage may occur. In this case, due to the blockage inside the pipe... The sealed design makes cleaning and unblocking difficult. Therefore, air can be drawn out using the air pump 16 on the back of the measuring instrument 1. The connection between the control pipe and the air pump can be manually adjusted using the handle at the reversing valve 14, allowing air to enter the low-pressure pipe 3 and the high-pressure pipe 2 through the air pump 16 for pressurization. When the pressure is high, it can flush out the blockages inside the pipe through the air inlet, effectively cleaning the blockages and preventing blockages. When it is necessary to replace the pipe and its components, the connector 11 can be removed from the pipe to be tested, and the screw sleeve 9 can be turned to move the fixed bushing 8 downward, separating the protective shell 5 and the mating shell 6 for quick replacement of parts.

[0031] 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.
