Detailed implementation
[0020] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
[0021] Embodiment 1
[0022] As Figures 1 to 3 shown, a noise and vibration detector with a temperature measurement function according to this solution includes: an analyzer housing 11. A noise and vibration detector is installed inside the analyzer housing 11, and the running noise and vibration of the device can be detected through this noise and vibration detector. A temperature measurement component is also installed outside the analyzer housing 11, so as to detect the temperature of the object to be measured through the temperature measurement component.
[0023] Specifically, the temperature measurement component includes: an outer housing 12. An infrared temperature probe 13 and a printed circuit board 14 are installed inside the outer housing 12, and the infrared temperature probe 13 is used to detect the temperature of the object to be measured. During installation, the infrared temperature probe 13 is electrically connected to the printed circuit board 14, and the printed circuit board 14 is electrically connected to the control circuit board provided in the noise and vibration detector, so as to integrate the detection information of the infrared temperature probe 13 into the control circuit board for specific data analysis. A laser ranging component 15 is also provided inside the outer housing 12. The distance from the infrared temperature probe 13 to the object to be measured can be detected through the laser ranging component 15, so as to ensure the accuracy of the detection distance of the infrared temperature probe 13, and further ensure the accuracy of the temperature detection information of the infrared temperature probe 13.
[0024] The above-mentioned noise and vibration detector with a temperature measurement function can not only detect the noise and vibration amplitude of an object by installing the infrared temperature probe 13 on the analyzer housing 11, but also detect the temperature of the object, so that the specific operating state of the object device can be more accurately estimated through the temperature information and vibration information, which is helpful for the fault diagnosis and predictive maintenance of the device. At the same time, the accuracy of the temperature detection of the object by the infrared temperature probe 13 can be ensured through the laser ranging component 15.
[0025] As a specific implementation, the laser distance measurement component 15 includes: two laser modules 151 and a bracket 152. The bracket 152 is formed with two mounting grooves 1521, and the two laser modules 151 are respectively installed into the corresponding mounting grooves 1521, so as to fix the laser modules 151 on the bracket 152. Specifically, the laser module 151 is inserted into the mounting groove 1521 and is detachably installed in the mounting groove 1521 through a set screw 17, which is convenient for disassembly and assembly, has good locking performance, and high structural stability. The bracket 152 is formed with a flexible adjustment portion 1522 between the two mounting grooves 1521, and the laser directions of the two laser modules 151 can be adjusted through the flexible adjustment portion 1522. The outer housing 12 is formed with two through holes 121, and the laser-emitting ends of the two laser modules 151 respectively face the corresponding through holes 121, so as to emit the laser through the through holes 121.
[0026] The bracket 152 is made of a metal material, so as to have a certain deformation ability. In this solution, the bracket 152 is made of brass material.
[0027] Specifically, the distance between the infrared temperature probe 13 and the object to be measured can be fixed through the above-mentioned laser distance measurement component 15. That is to say, taking advantage of the characteristic that the metal bracket 152 can deform under external force and is not easy to rebound, the laser module 151 fixed on the bracket 152 can change the direction of the laser beam as the bracket 152 deforms, and the purpose of the two laser beams converging is achieved by appropriately adjusting the direction of the laser beam. Before adjusting the bracket 152, the laser beams emitted by the laser module 151 are relatively parallel (as Figure 4 shown). When adjusting the bracket 152, since the bracket 152 is made of brass, only a certain external force needs to be applied to make it deform and is not easy to rebound. Here, the bracket 152 can also be made of other metals or materials with flexible properties of deformation and non-rebound. Therefore, only three forces F (as Figure 5 shown) need to be applied to the bracket 152 in the horizontal direction to make the two laser beams approach each other until they converge at a point at a fixed distance within the laser range. This fixed distance can be adjusted according to actual requirements. In this way, the distance between the object to be measured and the infrared temperature probe 13 can be limited and determined through this point where the two laser beams converge. Since the middle area of the bracket 152, that is, the flexible adjustment portion 1522, is designed to be the weakest, that is, the width and thickness of the middle area of the bracket 152 are designed to be smaller than those of the two ends, the deformation of the bracket 152 mainly concentrates in this area (as Figure 5As shown in the deformation area of the bracket 152, it will not affect or have very little impact on the fixation of the laser module 151, thus avoiding loosening of the part of the bracket 152 that fixes the laser module 151. The "distance setting" function can be achieved through the above method.
[0028] After the above-mentioned noise and vibration detector with temperature measurement function is assembled, when the user holds the instrument and moves it back and forth until the two laser beams on the surface of the object to be measured intersect at the same point, it means that the distance between the two reaches the detection requirement at this time. Generally, there is a distance standard for noise measurement, that is, it is required to maintain a certain distance between the instrument and the noise source, that is, the instrument needs to set the distance during measurement. This distance setting is beneficial to improving the accuracy of noise and vibration detection. For the infrared temperature probe 13, when measuring temperature, it also needs to be within a certain distance range from the object to be measured. The distance setting standard of the instrument here is determined according to the requirements of the actual instrument model. Therefore, considering the above two points, the ranging distance of the laser ranging component 15 is limited to a distance value according to the actual situation, which is beneficial to the accuracy of noise and vibration detection and also ensures the accuracy of temperature detection of the infrared temperature probe 13.
[0029] Furthermore, the connecting piece 154 is made of a hard metal material. In this way, when fine-tuning the laser module 151, the transmission of torque is more accurate, and it will not affect or have very little impact on the support installation structure of the laser module 151, which can be ignored. This can ensure the stability of the installation structure of the overall laser ranging component 15.
[0030] As a specific implementation manner, a glass sheet 16 is provided in the through hole 121. By providing the glass sheet 16, the through hole 121 can be closed and the laser can be transmitted through it. In addition, the outer shell 12 is formed with a jack 124 for the end of the infrared temperature probe 13 to be inserted, and a sealing ring 18 is provided between the infrared temperature probe 13 and the hole wall of the jack 124 to seal the interior of the outer shell 12. Through the above structure, not only can the stability of the overall temperature measurement structure of the device be ensured, but also the device as a whole has good waterproof performance.
[0031] As a specific implementation manner, the printed circuit board 14 is provided with two connection interfaces 141. The analyzer housing 11 is formed with two through grooves 111 respectively corresponding to the corresponding connection interfaces 141. The printed circuit board 14 is electrically inserted into the control circuit board provided in the noise and vibration detector through the connection interfaces 141 passing through the corresponding through grooves 111. By connecting the printed circuit board 14 and the control circuit board through such a structure, not only the electrical insertion function is realized, but also the installation position between the analyzer housing 11 and the outer shell 12 is pre-positioned through the structural cooperation of the through grooves 111 and the connection interfaces 141, and the structural assembly efficiency is high and more accurate.
[0032] Further, the outer housing 12 is formed with a mounting surface 122, and the analyzer housing 11 is formed with a mating surface 113 for mating with the mounting surface 122. The mounting surface 122 is formed with threaded holes 123, and the mating surface 113 is formed with mounting holes 112 corresponding to the threaded holes 123. The outer housing 12 is fixed to the analyzer housing 11 by screws 19 passing through the mounting holes 112 and screwing into the threaded holes 123. Such mating of the surfaces has a high degree of fit and good waterproof and dustproof performance. When designing, a slot for the mounting surface 122 to snap into may be provided at the position of the mating surface 113 corresponding to the mounting surface 122, and a sealing ring 18 may be provided in the slot to further improve the sealing performance of the mounting structure and the overall structural stability.
[0033] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
