Description

Technical Field

[0001] This utility model relates to the field of air intake flow nozzle measurement technology, and in particular to an air intake flow nozzle measurement component. Background Technology

[0002] A nozzle flow meter is a differential pressure generating device for measuring flow rate. When used with various differential pressure gauges or differential pressure transmitters, it can measure the flow rate of various fluids in pipelines. Standard nozzle throttling devices are used in conjunction with differential pressure transmitters to measure the flow rate of liquids, steam, and gases.

[0003] A search of the intake flow nozzle assembly and intake flow measuring device with publication number CN212228124U reveals that it includes multiple nozzle flow meters and a connector with multiple connecting through holes arranged in an array. Each nozzle flow meter is correspondingly installed within one of the connecting through holes. A predetermined number of nozzle flow meters, evenly distributed relative to the connector, can be activated simultaneously to ensure that the upper limit of the intake flow nozzle assembly reaches a predetermined intake flow rate. This intake flow nozzle assembly and intake flow measuring device, by combining a predetermined number of nozzle flow meters, are highly flexible and applicable to intake flow measurement in various types and power ratings of gas turbines.

[0004] However, when using the above-mentioned device, it is necessary to periodically disassemble the connecting pipe from the nozzle flow meter and clean the inner wall of the connecting pipe to prevent impurities from accumulating and affecting the flow measurement. This cleaning method is relatively complicated, increases the workload, and reduces the cleaning efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an intake flow nozzle measuring component to solve the problem mentioned in the background art, where the device requires periodic disassembly of the connecting pipe from the nozzle flow meter and cleaning of the inner wall of the connecting pipe to prevent impurities from accumulating and affecting the flow measurement. This cleaning method is relatively complicated, increases the workload, and reduces cleaning efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an intake flow nozzle measuring component, comprising:

[0008] main body;

[0009] A fixing mechanism, the fixing mechanism including a flange fixedly connected to the outer wall of the flange of the body;

[0010] The cleaning mechanism includes a mounting groove formed on the inner wall of the flange, an external gear ring rotatably connected to the inner wall of the mounting groove, a meshing groove formed on the outer wall of the flange, and a gear meshing on the outer circumference of the external gear ring.

[0011] The gear is rotatably connected to the outer wall of the meshing groove, and the external gear ring extends out of one end of the meshing groove and meshes with the gear.

[0012] Furthermore, a connecting pipe is fixedly connected to the inner wall of the flange, and a fixed cylinder is symmetrically fixedly connected to the inner cavity of the flange. A button is slidably connected to the inner circumference of the fixed cylinder.

[0013] Furthermore, a spring and a push rod are fixedly connected to the outer wall of the button, the end of the spring is fixedly connected to the inner wall of the fixed cylinder, and a groove is provided on the outer circumference of the end of the push rod;

[0014] Furthermore, the spring is sleeved on the outer circumference of the push rod, and a limit ball is slidably connected to the inner wall of the fixed cylinder;

[0015] The limiting ball is located near the groove;

[0016] Furthermore, a motor is fixedly connected to the outer wall of the flange, and a sealing cover corresponding to the meshing groove is fixedly connected to the outer wall of the flange, with the gear located inside the sealing cover.

[0017] The motor output end is fixedly connected to the gear, and the motor is fixedly connected to the outer wall of the sealing cover;

[0018] Furthermore, connecting plates are fixedly connected to the outer walls on both sides of the outer gear ring at equal intervals around the circumference, and cleaning rollers are fixedly connected to the outer walls of the connecting plates;

[0019] The cleaning roller contacts the inner wall of the connecting pipe;

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] I. This utility model, when it is necessary to clean the inner wall of the connecting pipe, uses a set installation groove, an outer gear ring, a gear, a motor, a connecting plate, and a cleaning roller for cleaning. Turning on the motor drives the gear to rotate, the gear drives the outer gear ring to rotate, the outer gear ring drives the connecting plate to rotate, and the connecting plate drives the cleaning roller to rotate. The rotating cleaning roller cleans the inner wall of the connecting pipe, reducing the accumulation of impurities and avoiding the need to disassemble the connecting pipe, allowing for direct cleaning.

[0022] II. Based on the first beneficial effect, when installing the connecting pipe on the nozzle flow meter, first install the flange on the main body and insert the fixing cylinder into the main body. Manually press the button to drive the push rod to move. The push rod moves and drives the limit ball to slide to the groove. Release the button, and the spring will return the push rod to its original position. The push rod moves and drives the limit ball to slide from the groove to the end of the push rod and fully contact the inner wall of the fixing cylinder, thereby limiting the flange. This can facilitate the limiting of the connecting pipe before the connecting pipe is fixedly installed, which is convenient for subsequent fixing with screws. Attached Figure Description

[0034] Please see Figure 1-4 As shown, this embodiment is an intake flow nozzle measurement assembly, including:

[0035] Entity 1;

[0036] The fixing mechanism 2 includes a flange 201 that is fixedly connected to the outer wall of the flange of the main body 1;

[0037] The connecting pipe 202 is fixedly connected by connecting the flange 201 to the main body 1;

[0038] The cleaning mechanism 3 includes a mounting groove 301 opened on the inner wall of the flange 201. An external gear ring 302 is rotatably connected to the inner wall of the mounting groove 301. A meshing groove is opened on the outer wall of the flange 201. A gear 303 meshes with the outer circumference of the external gear ring 302.

[0039] Among them, gear 303 is rotatably connected to the outer wall of the meshing groove, and external gear ring 302 extends out of the meshing groove and meshes with gear 303;

[0040] The mounting slot 301 provides rotational support for the external gear ring 302, and the meshing slot causes the gear 303 to drive the external gear ring 302 to rotate.

[0041] A motor 304 is fixedly connected to the outer wall of flange 201, and a sealing cover 307 corresponding to the meshing groove is fixedly connected to the outer wall of flange 201. Gear 303 is located in the inner cavity of sealing cover 307.

[0042] The output end of the motor 304 is fixedly connected to the gear 303, and the motor 304 is fixedly connected to the outer wall of the sealing cover 307.

[0043] The motor 304 is supported by the flange 201, the motor 304 provides power to the gear 303, the gear 303 drives the external gear ring 302 to rotate, and the sealing cover 307 seals and protects the meshing groove.

[0044] The outer toothed ring 302 has connecting plates 305 fixedly connected to its outer walls on both sides at equal intervals around its circumference, and cleaning rollers 306 are fixedly connected to the outer walls of the connecting plates 305.

[0045] Among them, the cleaning roller 306 contacts the inner wall of the connecting pipe 202;

[0046] The external gear ring 302 drives the cleaning roller 306 to rotate via the connecting plate 305 to clean the inner wall of the connecting pipe 202;

[0047] Working principle: When the inner wall of the connecting pipe 202 needs to be cleaned, it is cleaned through the set mounting groove 301, outer gear ring 302, gear 303, motor 304, connecting plate 305, and cleaning roller 306. When the motor 304 is turned on, it drives the gear 303 to rotate, the gear 303 drives the outer gear ring 302 to rotate, the outer gear ring 302 drives the connecting plate 305 to rotate, and the connecting plate 305 drives the cleaning roller 306 to rotate. The rotating cleaning roller 306 cleans the inner wall of the connecting pipe 202.

[0048] This step can reduce the accumulation of impurities, avoid the need to disassemble the connecting pipe 202, and allow for direct cleaning.

[0049] Please see Figure 1-4 As shown, this embodiment, based on embodiment 1 above, further includes:

[0050] A connecting pipe 202 is fixedly connected to the inner wall of flange 201, and a fixed cylinder 203 is symmetrically fixedly connected to the inner cavity of flange 201. A button 204 is slidably connected to the inner circumference of the fixed cylinder 203.

[0051] The fixed cylinder 203 is supported by the flange 201, and the button 204 is supported by the fixed cylinder 203;

[0052] A spring 206 and a push rod 205 are fixedly connected to the outer wall of the button 204. The end of the spring 206 is fixedly connected to the inner wall of the fixed cylinder 203. A groove 207 is opened on the outer circumference of the end of the push rod 205.

[0053] Spring 206 is sleeved on the outer circumference of push rod 205, and limit ball 208 is slidably connected to the inner wall of fixed cylinder 203;

[0054] Among them, the limiting ball 208 is close to the groove 207;

[0055] The push rod 205 is moved by the button 204, and the limit ball 208 is slid to the groove 207 by the push rod 205 so that it does not contact the inner wall of the fixed cylinder 203. The push rod 205 is returned by the spring 206, so that the limit ball 208 slides to contact the inner wall of the fixed cylinder 203, thereby limiting the flange 201.

[0056] Working principle: When installing the connecting pipe 202 on the nozzle flow meter, first install the flange 201 on the main body 1 so that the fixed cylinder 203 is inserted into the main body 1. Manually press the button 204 to drive the push rod 205 to move. The movement of the push rod 205 causes the limiting ball 208 to slide to the groove 207. Release the button 204, and the spring 206 will return the push rod 205 to its original position. The movement of the push rod 205 will cause the limiting ball 208 to slide from the groove 207 to the end of the push rod 205 and fully contact the inner wall of the fixed cylinder 203, thereby limiting the flange 201.

[0057] This step allows the connecting pipe 202 to be easily positioned before it is fixedly installed, making it easier to fix it with screws later.
