[0005] In view of the problems existing in the above-mentioned intelligent monitoring equipment based on MEMS inertial sensors, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an intelligent monitoring device based on MEMS inertial sensors, which solves the problem that existing intelligent monitoring devices based on MEMS inertial sensors generate a lot of dust during daily use, which makes it impossible for the monitoring device to clearly detect the area and causes important information to be missed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A smart monitoring device based on a MEMS inertial sensor includes a base and a monitoring device body. The upper surface of the base has a mounting groove, and two grooves are symmetrically formed inside the base. Each groove has a fixing mechanism. The monitoring device body is fixedly connected to the inside of the mounting groove through the two fixing mechanisms. A glass protective cover is fixedly connected to the upper surface of the base. The upper surface of the base has a first annular groove, and an annular block is rotatably connected inside the first annular groove.

The two trapezoidal sliders are slidably disposed inside corresponding sliding grooves. The two screws are rotatably connected to the lower surface of the corresponding trapezoidal sliders. The lower ends of the two screws pass through one side of the corresponding sliding grooves and are fixedly connected to the corresponding knobs. The two T-shaped blocks are fixedly connected to the inclined surfaces of the corresponding trapezoidal sliders. Each of the inclined surfaces of the two trapezoidal inserts has a T-shaped groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, through a drive mechanism that rotates the annular block and the arc-shaped cleaning brush, can automatically remove dust and debris from the outer surface of a hemispherical glass protective cover. The arc-shaped design of the cleaning brush fits snugly against the curved surface of the protective cover, ensuring no cleaning dead corners, maintaining the light transmittance of the glass protective cover, preventing blurry monitoring images due to dust accumulation, effectively ensuring the clarity of area detection by the monitoring equipment, and reducing the omission of important information.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses an intelligent monitoring device based on a MEMS inertial sensor.

[0026] This utility model provides, for example Figure 1-3 The intelligent monitoring device based on MEMS inertial sensors shown includes a base 1 and a monitoring device body 2. The upper surface of the base 1 has a mounting groove, and two grooves are symmetrically formed inside the base 1. Each groove has a fixing mechanism. The monitoring device body 2 is fixedly connected to the inside of the mounting groove through the two fixing mechanisms. A glass protective cover 3 is fixedly connected to the upper surface of the base 1. A first annular groove is formed on the upper surface of the base 1, and an annular block 4 is rotatably connected inside the first annular groove. An arc-shaped cleaning brush 5 is fixedly connected to the upper surface of the annular block 4. A cavity is formed inside the base 1, and a driving mechanism is set inside the cavity. The annular block 4 is rotated by the driving mechanism.

[0027] The main body of the monitoring device 2 is a camera equipped with a MEMS inertial sensor. Its main function is to determine whether there is an abnormality by monitoring the behavior of objects. When it is working, rotating the ring block 4 can rotate the cleaning brush 5, so that the cleaning brush 5 can clean the glass protective cover 3, allowing the main body of the monitoring device 2 to clearly detect the area.

[0028] To facilitate the installation and removal of the monitoring device body 2, such as Figure 2-3 As shown, the fixing mechanism includes two trapezoidal inserts 6, two trapezoidal sliders 7, two T-shaped blocks 8, two screws 9, and two knobs 10. The two trapezoidal sliders 7 are slidably disposed inside the corresponding grooves. Each of the two grooves has a sliding groove on one side. The two trapezoidal sliders 7 are slidably disposed inside the corresponding sliding grooves. The two screws 9 are rotatably connected to the lower surface of the corresponding trapezoidal sliders 7. The lower ends of the two screws 9 pass through one side of the corresponding sliding groove and are fixedly connected to the corresponding knobs 10. The two T-shaped blocks 8 are fixedly connected to the inclined surfaces of the corresponding trapezoidal sliders 7. Each of the inclined surfaces of the two trapezoidal inserts 6 has a T-shaped groove. The two T-shaped blocks 8 are slidably disposed inside the corresponding T-shaped grooves. The side wall of the monitoring device body 2 has two slots symmetrically provided. The two slots are matched with the corresponding trapezoidal inserts 6. Each of the two sliding grooves has an internal threaded hole. The two internal threaded holes are matched with the corresponding screws 9.

[0029] When installing the monitoring device body 2, first rotate knob 10. Knob 10 drives screw 9 to rotate in the internal threaded hole of the slide groove. Since screw 9 is rotatably connected to trapezoidal slider 7, the rotation of screw 9 will push trapezoidal slider 7 to slide horizontally in the groove. The inclined surface of trapezoidal slider 7 is fixedly connected to T-block 8. When trapezoidal slider 7 slides, T-block 8 slides in the T-groove of the inclined surface of trapezoidal insert 6, pushing trapezoidal insert 6 towards the monitoring device body 2 until trapezoidal insert 6 is fully inserted into the slot on the side wall of monitoring device body 2, thus achieving mechanical fixation of the device. The rotation of knob 10 provides locking force through the threaded transmission of screw 9, ensuring that trapezoidal insert 6 is tightly fitted with the slot and preventing the monitoring device body 2 from loosening. When disassembling, rotate knob 10 in the opposite direction. Trapezoidal slider 7 drives T-block 8 and trapezoidal insert 6 to reset, and the device can then be removed.

[0030] To make the annular cleaning brush 5 rotate, such as Figure 1-2 As shown, the drive mechanism includes a motor 11, an external gear ring 12, and a gear 13. The inner wall of the first annular groove is surrounded by a second annular groove. The external gear ring 12 is fixedly sleeved on the outer surface of the annular block 4. The motor 11 is fixedly connected to the upper surface inside the cavity. The output end of the motor 11 passes through the upper surface of the cavity and extends into the interior of the second annular groove. The gear 13 is fixedly sleeved on the output end of the motor 11 and meshes with the external gear ring 12.

[0031] When dust accumulates on the outer surface of the glass protective cover 3, the motor 11 of the drive mechanism is started. The gear 13 at the output end of the motor 11 meshes with the outer gear ring 12 on the outer surface of the annular block 4. The rotation of the motor 11 drives the gear 13 to rotate, and through gear transmission, the annular block 4 is driven to make circular motion in the first annular groove. The arc-shaped cleaning brush 5 on the upper surface of the annular block 4 rotates synchronously with the annular block 4. Its bristles are in contact with the outer surface of the hemispherical glass protective cover 3, and dust and debris are removed through rotational friction.

[0032] In order to thoroughly clean the glass protective cover 3, such as Figure 1-2 As shown, the glass protective cover 3 is hemispherical, and the arc-shaped cleaning brush 5 is attached to the outer surface of the glass protective cover 3.

[0033] The curved design of the cleaning brush matches the curved surface of the glass protective cover, ensuring coverage of the entire sphere with no blind spots.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
