[0028] As shown in FIG. Figures 1-5 The utility model provides a composite sensor, which comprises:

[0029] A shell 1 is provided with an integrated plug 2 at the bottom, an elastic buffer at the top and a sensor mounting hole 3 at the side; the shell 1 can be of any shape, and as a preferred option, a cuboid-shaped shell 1 is adopted; the integrated plug 2 is generally in the form of a combination structure of an integrated bus and a plurality of pin-type plugs, and is inlaid and fixed at the bottom of the shell 1 and connected outwardly to a data processing device for collecting data of the sensor 5; the shell 1 is mounted on the monitored equipment, and the mounting mode can be fixed welding or detachable connection with an ear plate and a bolt; the sensor mounting hole 3 provided at the side of the shell 1 is generally used for mounting a vibration sensor and other sensors 5 that are not sensitive to vibration; since the shell 1 is directly fixed on the monitored equipment, its vibration characteristics are consistent with those of the equipment, and in particular for some parts with high-speed movement such as electromechanical drive and transmission devices in the equipment, the vibration sensor can collect accurate vibration data.

[0030] A cross-shaped support is horizontally fixed at the upper end of the elastic buffer; the fixed connection point of the cross-shaped support is located at the central position to achieve horizontal balance.

[0031] The sensor clamp 4 is rotationally connected to the end of the cross-shaped support. Because of the buffering function of the elastic buffer, the vibration degree of the cross-shaped support is far less than the vibration degree of the shell 1, so the performance of the sensor 5 on the sensor clamp 4 affected by the vibration of the machine equipment can be greatly reduced. For example, the installation of an optical sensor on the sensor clamp 4 can reduce the optical signal jitter and improve the accuracy of the detection point positioning.

[0032] The sensor mounting hole 3 and the sensor clamp 4 are provided with a plurality of sensors 5, and the sensors 5 are respectively electrically connected to the integrated plug 2.

[0033] When using this multiplex sensor, because the sensor mounting hole 3 provided on the shell 1 and the sensor clamp 4 connected to the cross-shaped support can both install the sensor 5, only one such multiplex sensor needs to be installed on the equipment to realize multiple detection functions, and the integrated plug 2 can realize centralized wiring, which is convenient for management and maintenance. By providing an elastic buffer, a vibration sensor can be installed on the shell 1, and a sensor 5 with high stability requirement can be installed on the sensor clamp 4. By installing the shell 1 on the equipment, the vibration isolation between the sensors 5 can be realized while multiplexing multiple sensors 5. The structure design of the elastic buffer makes the multiplex sensor not only collect accurate vibration data of the equipment, but also avoid the adverse effects of equipment vibration characteristics on the detection performance of the sensor 5.

[0034] In another technical solution, as shown in Figure 3 The elastic buffer includes an upper clamp plate 6, a lower clamp plate 7, and a support rod connected between the two plates. The upper clamp plate 6 and the lower clamp plate 7 are respectively arranged on the outside and the inside of the shell 1, and the support rod passes through the top of the shell 1. The two sections of the support rod inside and outside the shell 1 are both sleeved with springs. The upper clamp plate 6 and the lower clamp plate 7 are respectively arranged on the outside and the inside of the shell 1, and there is a certain interval for accommodating the springs above and below the top of the shell 1. Each cylindrical support rod is sleeved with two springs, which provide support inside and outside the shell 1, and the spring outside the shell 1 has a relatively larger elastic coefficient to better support the cross-shaped support. A certain length of transition connection section can be provided between the upper clamp plate 6 and the cross-shaped support. When the vibration force of the shell 1 is transmitted upward, the vibration is eliminated through the buffering of the spring, ensuring the stability of the cross-shaped support and the sensor clamp 4.

[0035] The power controller 15 is arranged in the shell 1, and the integrated plug 2 and the sensor 5 are electrically connected to the power controller 15. The external data management equipment is connected to the power controller 15 through the integrated plug 2, and the detection data of all sensors 5 can be collected and the working state of each sensor 5 can be directly controlled through the power controller 15.

[0036] In another technical solution, as shown in Figures 1-5 The cross-shaped support includes a cross-shaped pipe and a rotating shaft 9, the cross-shaped pipe is formed by four sleeves 8, the top of the sleeve 8 is provided with a first horizontal groove 10 along the length direction of the pipe, a first vertical groove 12 and a second vertical groove 13 are respectively arranged at both sides of the first horizontal groove 10, the first vertical groove 12 extends from the top to the bottom of the sleeve 8 along the wall, a second horizontal groove 11 is arranged at the middle position of the first vertical groove 12 along the length direction of the sleeve 8, and the length of the second vertical groove 13 is half of the first vertical groove 12; one end of the rotating shaft 9 is connected with the sensor clamp 4, the other end is rotatably inserted into the sleeve 8 and fixedly connected with a limiting screw rod 14, the limiting screw rod 14 is slidingly connected in the first horizontal groove 10, the first vertical groove 12, the second vertical groove 13 or the second horizontal groove 11 and matched with a locking nut. The insertion depth and the rotation angle of the rotating shaft 9 in the sleeve 8 are changed by sliding and rotating, and the sensor clamp 4 has different orientations when the limiting screw rod 14 is in different grooves, as an example, when the connecting direction of the limiting screw rod 14 on the rotating shaft 9 is consistent with the orientation of the sensor clamp 4, there are the following angle states: when the limiting screw rod 14 is located in the first horizontal groove 10, the sensor clamp 4 is upward; when the limiting screw rod 14 is located at the lower end of the first horizontal groove 10, the sensor clamp 4 is downward; when the limiting screw rod 14 is located in the second horizontal groove 11 or the lower end of the second vertical groove 13, the sensor clamp 4 is horizontally oriented to both sides, respectively, after adjusting the limiting screw rod 14 to the required position, the sensor clamp 4 can be directly fixed at the corresponding orientation angle by matching the locking nut, and the orientation angle can be adjusted at any time. By the rotating cooperation between the sleeve 8 and the rotating shaft 9 of the cross-shaped support, the sensor 5 can be adjusted and fixed at multiple angles, which is suitable for installing the sensor 5 with direction requirements, and since the limiting screw rod 14 is limited in a groove, the angle of the sensor clamp 4 can be more stably maintained.

[0037] As shown in Figure 2 and Figure 3 The first vertical groove 12 starts from one end of the first horizontal groove 10 away from the joint of the sleeve 8, and the second vertical groove 13 starts from the middle position of the first horizontal groove 10. By arranging the positions of the grooves, when the rotating shaft 9 is inserted into the sleeve 8 to the deepest, the sensor clamp 4 is upward, when the rotating shaft 9 is inserted into the sleeve 8 to the shallowest, the sensor clamp 4 is downward, and when the rotating shaft 9 is inserted into the sleeve 8 to the middle, the sensor clamp 4 is oriented to both sides, so that the angle adjustment of the sensor clamp 4 is more convenient and fast.

[0038] In another technical solution, as shown in Figure 4 and Figure 5As shown, the sensor clamp 4 includes a connecting block, a base and a clamp, the connecting block is connected with the cross-shaped support, the base and the clamp are oppositely arranged at two ends of the connecting block, the sensor 5 is fixed in the clamp, and the base is provided with a sensor socket which is electrically connected with the integrated plug 2. The clamp of the sensor clamp 4 is used for fixing the main body of the sensor 5, and the sensor socket of the base is used for data connection with the sensor 5, so that the fixing stability and the connection stability of the sensor 5 are ensured.

[0039] The connecting block is detachably connected to the end of the cross-shaped support. The detachable connection structure can adopt a threaded connection or a fastener fixing mode, so that different sensor clamps 4 can be replaced to adapt to different sizes and types of sensors 5, especially for some special-shaped sensors 5, a special sensor clamp 4 can be used.

[0040] As shown in the figure, Figure 1 The sensor socket is an aviation socket, the aviation socket is connected with a data line, the data line is sequentially connected to the integrated plug 2 after passing through the inside of the cross-shaped support, the upper clamping plate 6, the top of the shell 1 and the lower clamping plate 7. By arranging the data line in the cross-shaped support and the shell 1, centralized wiring management can be realized, and the problems of line management confusion and maintenance difficulty are avoided. For example, in the above scheme, the cross-shaped support is spliced by a sleeve 8, has a hollow structure, and the rotating shaft 9 can also be arranged in a hollow form, and a hole is formed downward in the center of the cross-shaped support, so that the wiring from the aviation socket to the integrated plug 2 can be completed from the inside.

[0041] The number of devices and the scale of processing described here are used to simplify the description of the present application. The application, modification and change of the present application are obvious to those skilled in the art.

[0042] Although the embodiments of the present application have been disclosed as above, it is not limited to the application and the embodiments listed in the specification, it can be fully applied to various fields suitable for the present application, and other modifications can be easily realized by those skilled in the art, therefore, the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
