Description

Technical Field

[0001] The utility model relates to the field of acceleration sensor protection devices, in particular to a protection device for an acceleration sensor. Background Technique

[0002] Acceleration sensors are sensors used to detect or monitor the vibration of structures. They usually consist of a series of sensing elements, which can be of types such as optoelectronic, capacitive, magnetic, ultrasonic, or laser. Acceleration sensors are widely used in civil engineering, aerospace, mechanical manufacturing, automotive manufacturing, quality inspection, and other fields.

[0003] Currently, acceleration sensors may be subject to external force impacts, erosion, or wear, such as the erosion of the natural environment during structural monitoring, which affects the service life and monitoring accuracy of the device. For example, water vapor, rain, snow, hail, dust, etc. in the atmosphere. At the same time, they are also often damaged by impacts or other external forces, including but not limited to human damage, falling object impacts, vehicle impacts, etc. In these cases, using a device with a protective cover can protect the cables and housings of the sensors and avoid damage caused by external forces. In the installation and replacement process of existing acceleration sensor protection devices, the protection block and the base are connected by bolts, and comprehensive protection cannot be achieved. There is an open end for equipment installation and debugging, which does not play a comprehensive protection role. In addition, there are a series of problems such as difficult installation, relatively cumbersome operation methods, lack of simplicity, and inability to directly observe the working state of the sensor. Moreover, due to the high requirements for installation accuracy in material selection, loose installation may affect the vibration conditions of the measured structure.

[0004] Therefore, it is necessary to provide a new protection device for an acceleration sensor to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a protection device for an acceleration sensor.

[0006] A protection device for an acceleration sensor provided by the utility model includes a base, and the inner wall of a limiting groove opened at the top of the base is connected with a protective cover through two connecting components;

[0007] The connecting component includes a pushing plate, a driving block, and a number of elastic members. The number of elastic members is fixedly connected to the inner wall of the limiting groove opened at the top of the base, and one ends of the number of elastic members away from the inner wall of the limiting groove opened on the base are respectively fixedly connected with two clamping blocks. One ends of the two clamping blocks are fixedly connected with movable blocks, one ends of the movable blocks are fixedly connected with pushing blocks. The pushing plate is movably connected to the inner wall of the limiting groove opened at the top of the base, the driving block is fixedly connected to one end of the pushing plate, and the end of the driving block away from the pushing plate is arc-shaped.

[0008] Preferably, the elastic member is a compression spring, and the compression spring is fixedly connected to the inner wall of the limiting groove formed in the top of the base, and one end of the compression spring away from the inner wall formed in the base is fixedly connected to one end of the clamping block respectively.

[0009] Preferably, an acceleration sensor body is fixedly connected to the top of the base, and the acceleration sensor body is arranged inside the protective cover.

[0010] Preferably, the protective cover is made of a light material.

[0011] Preferably, the light material is transparent acrylic.

[0014] Compared with the related art, a protection device for an acceleration sensor provided by the present utility model has the following beneficial effects:

[0015] Through the provided connection assembly, when the acceleration sensor needs to be repaired, first press the push plate towards the push block. The push plate will drive the driving block to move towards the push block, and drive the movable block and the clamping block to move away from the protective cover through the driving block and the push block, and extrude the elastic member, so as to remove the protection plate and repair the acceleration sensor. This device solves the problem that it is necessary to drive the fixed threaded rod and the wedge block through a knob to remove the outer shell, and this operation method is relatively cumbersome and not simple enough, and reduces the influence on the timely repair and recovery of the device that may be caused by too long operation time.
