For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The microcomputer protection device is composed of a high-integration, bus-free chip microcomputer, a high-precision current and voltage transformer, a high-insulation-strength output intermediate relay, a high-reliability switching power supply module and other components. The microcomputer protection device has extremely strong data processing, logic operation and information storage capabilities, and has an advanced core structure. With the complete protection functions of conventional relay protection, the microcomputer protection device can monitor, control and protect the state of the circuit through the signals of the connected current transformer, voltage transformer and other measuring components.

[0044] In the related art, the microcomputer is directly placed in the protective device, and no fixed protective mechanism is set in the protective device. When the device needs to be moved, the microcomputer in the device is easily bumped and damaged, which reduces the service life of the microcomputer and has certain limitations.

[0045] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a microcomputer protection device for an electric power system. When the equipment storing the microcomputer needs to be moved, the vertical rod and the anti-slip pad can be gradually brought close to the microcomputer by manually turning the hand wheel to fix the microcomputer, so as to achieve the effect of fixing and protecting the microcomputer when moving, prevent the microcomputer from being bumped when moving, and make it more firm, thereby increasing the service life of the microcomputer.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] Combination Figure 1-Figure 4The present application provides a power system microcomputer protection device, including a main body component 1, the main body component 1 includes: a box body 11 with a box door 12 hinged on one side, a button 13 is arranged on the surface of the box body 11 near the box door 12, a protection component 2 is arranged inside the box body 11, and the protection component 2 includes: a moving mechanism 21 is arranged inside the box body 11, a fixing mechanism 22 is arranged on the top of the moving mechanism 21, and the fixing mechanism 22 includes: a vertical plate 221, which is symmetrically arranged at At the top of the moving mechanism 21, a reverse screw rod 222 is arranged between the vertical plates 221, one end of the reverse screw rod 222 passes through and is rotatably connected to the vertical plate 221 on one side, a threaded block 223 is symmetrically and threadedly connected to the reverse screw rod 222, a vertical rod 224 is arranged on the top of the threaded block 223, a placement block 225 is arranged at the top of the moving mechanism 21 and is located in the middle of the reverse screw rod 222, and a hand wheel 226 is arranged on one side of the reverse screw rod 222 passing through the vertical plate 221.

[0048] When in use, open the box door 12, use the moving mechanism 21 to slide the slide plate 213 out of the box body 11, and place the microcomputer on the top of the placement block 225. The vertical plate 221 supports the reverse screw rod 222, and the reverse screw rod 222 is rotatably connected to the vertical plate 221. Turn the hand wheel 226, and the hand wheel 226 drives the reverse screw rod 222 to rotate. Under the influence of the rotation of the reverse screw rod 222, the two threaded blocks 223 threadedly connected on the reverse screw rod 222 drive the top vertical rod 224 to approach or depart from each other according to the direction of rotation of the reverse screw rod 222. When the vertical rods 224 are controlled to approach each other, the microcomputer placed on the placement block 225 is fixed and protected to prevent the microcomputer from shaking during the movement. After the microcomputer is placed, the moving mechanism 21 is used again to slide the slide plate 213 and the fixed microcomputer into the box body 11, and the box door 12 is closed to complete the protection of the microcomputer.

[0049] In some embodiments, the moving mechanism 21 includes: a motor 211 whose output end passes through and is rotatably connected to a side of the box body 11 away from the box door 12, the motor 211 is electrically connected to the button 13, the button 13 can transmit a switch signal to the motor 211, the screw rod 212 is fixedly connected to the output end of the motor 211, a slide plate 213 is threadedly connected to the screw rod 212, and the slide plate 213 is slidably connected to the inside of the box body 11, the slider 214 is arranged at the bottom of the slider 213, and the bottom of the box body 11 is provided with a slide groove for the slider 214 to slide. After opening the box door 12, the button 13 is pressed, and the button 13 sends a switch signal to the motor 211, so that the motor 211 rotates, and the motor 211 drives the screw rod 212 to rotate. The slide plate 213 threadedly connected to the screw rod 212 slides on the bottom surface of the box body 11 with the help of the slider 214, and the fixing mechanism 22 on the top of the slide plate 213 is moved out of or retracted into the box body 11. There is no need to operate inside the box body 11, which is convenient for the staff to fix or repair the microcomputer.

[0050] In some embodiments, the facing surfaces of the vertical rod 224 are provided with anti-skid pads 23. The anti-skid pads 23 increase the contact area between the vertical rod 224 and the microcomputer, and at the same time increase the friction force, thereby increasing the stability of the microcomputer after being fixed.

[0051] In some embodiments, universal wheels 14 are symmetrically arranged at the bottom of the box 11. The universal wheels 14 enable the box 11 to be moved conveniently.

[0052] In some embodiments, a breathable net 24 is provided on one side of the box body 11 away from the box door 12. The microcomputer placed in the box body 11 generates heat during operation, and the breathable net 24 facilitates the heat dissipation of the microcomputer, preventing the microcomputer from being overheated during operation, affecting its use effect, or even causing damage to the microcomputer, thus shortening its service life.

[0053] In some embodiments, a spring 25 is disposed on the inner side wall of the air permeable net 24, and a protective plate 26 is disposed on the side of the spring 25 away from the air permeable net 24. When the microcomputer moves, the protective plate 26 protects the rear side of the microcomputer to prevent the rear side of the microcomputer from being bumped.

[0054] Specifically, the design of the spring 25 allows the protective plate 26 to be movable forward and backward, which is convenient for fixing microcomputers of different sizes. The threaded block 223 enables the mobility of the vertical rod 224 and the anti-slip pad 23, so that the device can fix microcomputers of different sizes and is highly practical.

[0055] In some embodiments, limit blocks 215 are provided on both sides of the motor 211. When the slide plate 213 slides out of the box 11, the limit blocks 215 limit the sliding distance of the slide plate 213 to prevent the slide plate 213 from slipping out of the box 11 and affecting the normal use of the device.

[0056] In some embodiments, the length of the slide groove at the bottom of the box body 11 is greater than the length of the slider 214. This allows the slider 214 to slide conveniently in the slide groove, increases the sliding distance of the slide plate 213, and facilitates the removal of the fixing mechanism 22.
