Detailed implementation manners

[0017] For the convenience of understanding the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation.

[0019] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which this invention belongs; the terms used in the specification of this invention are only for the purpose of describing specific implementations and are not intended to limit this invention; the term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0020] As Figures 1 to 3 shown, this application proposes a four-in-one multi-functional sensor, including a four-in-one sensor 100 and a device main body 200. The four-in-one sensor 100 is used to detect vibration, temperature, shock wave and sound of the device main body 200, and can timely discover faults of the device main body 200. The device main body 200 mainly includes rotating devices such as motors, water pumps, fans, compressors, and speed reducers, and variable-speed operating devices such as door machines, pumping units, and cranes. The four-in-one sensor 100 is electrically connected to a signal and data acquisition and analysis terminal, and the data of the device main body 200 collected by the four-in-one sensor 100 is transmitted to the data acquisition and analysis terminal. That is to say, the four-in-one sensor 100 can transmit various data of the device main body 200 collected in real time to the data acquisition and analysis terminal, enabling users to easily complete various inspection tasks and improving work efficiency and data accuracy; A magnetic base 110 is fixed at the bottom of the four-in-one sensor 100. The magnetic base 110 has magnetism and can magnetically adsorb on the monitoring position of the device main body 200. That is to say, the four-in-one sensor 100 can be fixed on the device main body 200 by magnetic attraction.

[0021] It should be noted that the four-in-one sensor 100 and the data acquisition and analysis terminal are used in combination. Through the functions provided by the data acquisition and analysis terminal, such as status monitoring, fault warning, fault judgment and analysis, health status assessment, operation and maintenance management, data management, and permission management, the running status of the device mechanism and various components such as bearings and rotating shafts can be monitored in real time, time domain, frequency spectrum, and trend analysis can be carried out, and other test and monitoring modules can also be integrated or extended according to user needs.

[0022] Specifically, as Figures 1 to 3 shown, the magnetic base 110 is a cylinder with a through groove in the middle, and a threaded groove 111 is opened in the through groove. A screw rod matching with the threaded groove 111 is fixed on the device main body 200. That is to say, a threaded connection is formed between the threaded groove 111 and the screw rod.

[0023] It should be noted that the four-in-one sensor 100 can be fixed at the monitoring position of the device body 200 by means of adhesion, magnetic attraction, screw connection, etc. according to specific circumstances.

[0024] In the above embodiment, the four-in-one sensor 100 is fixed on the device body 200 through the magnetic base 110. Through the four-in-one sensor 100, the operating device body 200 can be detected, realizing vibration detection, temperature detection, shock wave detection and sound detection of the device body 200, and transmitting the detected data to the data acquisition and analysis terminal in real time. By analyzing the detection data through the data acquisition and analysis terminal, when a failure of the device body 200 is detected, an early warning can be issued in time, enabling the user to easily complete various inspection tasks, thereby improving work efficiency and data accuracy.

[0025] In some embodiments of the present application, as Figures 3 to 6 shown, it further includes a protection component 300; The protection component 300 includes a dust-proof cover 310 and a positioning ring 320; The dust-proof cover 310 is a cylindrical mesh cover with a hollow interior and an opening at one end close to the magnetic base 110. The dust-proof cover 310 is located outside the four-in-one sensor 100. The dust-proof cover 310 is used to intercept dust in the working environment and play a protective role, which can prevent external objects from directly colliding with the four-in-one sensor 100, and a positioning ring 320 is fixed at the open end of the dust-proof cover 310; The positioning ring 320 is a metal ring and it can be adsorbed on the side of the magnetic base 110. That is to say, the dust-proof cover 310 can be magnetically positioned outside the four-in-one sensor 100 through the positioning ring 320, which is convenient for installation, simple in operation, and convenient for disassembling and cleaning the dust-proof cover 310 for repeated use.

[0026] It is worth noting that when the device body 200 is applied in an environment with a lot of dust and impurities, a large amount of dust and impurities covering the surface of the four-in-one sensor 100 will cause the performance of the four-in-one sensor 100 to decline, affecting its detection accuracy and stability.

[0027] Specifically, as Figures 3 to 6 shown, the diameter of the dust-proof cover 310 is not less than the diameter of the magnetic base 110, and the inner ring surface of the positioning ring 320 abuts against the side of the magnetic base 110.

[0028] It is easy to understand that there is a gap between the dust-proof cover 310 and the four-in-one sensor 100, and the dust intercepted by the dust-proof cover 310 will not contact the four-in-one sensor 100.

[0029] In the above embodiments, the dust cover 310 is fixed on the four-in-one sensor 100 through the positioning ring 320, and the dust cover 310 intercepts dust and impurities in the working environment, thereby ensuring the accuracy and stability of the operation of the four-in-one sensor 100.

[0030] In some embodiments of the present application, as Figures 6 to 11 shown, the protection component 300 further includes a mounting seat 330 and a marking portion 340; The mounting seat 330 is fixed on the side of the dust cover 310; The marking portion 340 includes a marking tube 342; The marking tube 342 is fixed on the mounting seat 330, and a marking pigment is stored in the marking tube 342. The marking pigment is used to mark the fault state of the device main body 200 to avoid omission during inspection. A nozzle 3421 is fixed on the marking tube 342 near the device main body 200, and the marking pigment is sprayed on the device main body 200 through the nozzle 3421.

[0031] It should be noted that when multiple device main bodies 200 fail, the fault devices are further marked through the marking portion 340, so that the inspection personnel can quickly find the fault devices when arriving at the scene and are not likely to miss any.

[0032] Specifically, as Figures 6 to 8 shown, the marking portion 340 further includes a through tube 341; One end of the through tube 341 extends into the marking tube 342, and the other end of the through tube 341 is connected to a micro air pump, and the micro air pump is fixed on the mounting seat 330.

[0033] It is easy to understand that the micro air pump is small in size, light in weight and low in cost. By introducing air into the through tube 341 through the micro air pump, the through tube 341 pressurizes the marking tube 342, so that the marking pigment is ejected from the nozzle 3421.

[0034] Specifically, as Figure 8 shown, the mounting seat 330 is a hollow arc-shaped plate and a heating sheet 331 is fixed inside it.

[0035] It is worth noting that the working performance of the four-in-one sensor 100 is affected in a low-temperature environment. The heating sheet 331 can play a role in heating and heat preservation, improving the safe operation of the four-in-one sensor 100. And when the four-in-one sensor 100 is installed by bonding in a low-temperature environment, it is necessary to increase the temperature at the monitoring position of the device main body 200 to avoid the influence of too low temperature on the bonding firmness. Then, before installing the four-in-one sensor 100, the side of the mounting seat 330 is first abutted against the monitoring position, and the monitoring position is preheated by the temperature generated by the heating sheet 331 to improve the installation firmness.

[0036] Specifically, as Figures 8 to 11 shown, one end of the through pipe 341 is fixed with a branch pipe 3411, and the branch pipe 3411 has two air outlet ends, at least two air outlet ends; There are two marking pipes 342. The marking pigment in one marking pipe 342 is red, and the marking pigment in one marking pipe 342 is yellow; One air outlet end of the branch pipe 3411 extends into one marking pipe 342.

[0037] It should be noted that the colors of the marking pigments in each marking pipe 342 are different. Different colors of marking pigments can be sprayed according to the severity of equipment failures, which is convenient for classifying faulty equipment. Among them, red indicates a serious failure, and yellow indicates a situation below a serious failure.

[0038] Specifically, as Figures 8 to 11 shown, two storage boxes 343 are fixed on the mounting base 330 near the positioning ring 320. One storage box 343 stores red marking pigment, and one storage box 343 stores yellow marking pigment; A connecting pipe 3431 is fixed on each storage box 343. The free end of one connecting pipe 3431 extends into one marking pipe 342. Valves are fixed on both air outlet ends of the branch pipe 3411. When one valve is opened, the other valve is closed.

[0039] It is easy to understand that the red marking pigment in the storage box 343 is sent into the marking pipe 342 with red marking pigment, and the yellow marking pigment in the storage box 343 is sent into the marking pipe 342 with yellow marking pigment, which can timely inject materials into the marking pipe 342.

[0040] Specifically, as Figures 8 to 11 shown, an elastic membrane 3422 is fixed in each marking pipe 342. The outer periphery of the elastic membrane 3422 is airtightly connected to the inner wall of the marking pipe 342. The inside of the marking pipe 342 is divided into two spaces by the elastic membrane 3422, an air inlet space and a feeding space, and the marking pigment is stored in the feeding space; The air outlet end of the branch pipe 3411 extends into the air inlet space, and the free end of the connecting pipe 3431 extends into the feeding space. A micro check valve 3432 is fixed on each connecting pipe 3431, and the micro check valve 3432 is used to prevent the marking pigment in the marking pipe 342 from entering the storage box 343.

[0041] On the basis of the above-mentioned embodiments, when a fault is detected in the device main body 200 and the fault is below a severe fault, one valve on the branch pipe 3411 is opened, air is introduced into the through pipe 341 by the micro air pump, air is introduced into the marking pipe 342 storing the yellow marking pigment, so that the elastic film 3422 deforms and pressurizes the marking pigment, and the device main body 200 sprays out the yellow marking pigment. When the micro air pump pumps air out of the through pipe 341, the yellow marking pigment in the corresponding storage box 343 can be sucked into the feeding space of the marking pipe 342 to timely supplement the marking pigment in the marking pipe 342, thereby reducing the injection time. Similarly, when it is detected that the fault of the device main body 200 is a severe fault, another valve on the branch pipe 3411 is opened, and the above actions are repeated, and the classification marking of the fault of the device main body 200 can be realized, thereby improving the efficiency of equipment maintenance.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
