[0002] Microprocessor-based protection devices are automated protection equipment used in power systems. They utilize the high-speed computing power and powerful logic judgment capabilities of microprocessors to monitor and analyze various electrical quantities in the power system in real time. When a fault or abnormal situation is detected, it can quickly issue a trip command to disconnect the faulty part, thereby protecting the safe and stable operation of power equipment and the power system.

[0003] When installing microcomputer protection devices, they are usually installed directly on the wall near the electrical cabinet. This allows the operator to easily observe the device and connect the wiring. However, the wiring ports of microcomputer protection devices are generally located on the back side. Therefore, when installing new wiring, the microcomputer protection device must first be removed from the wall surface before the wiring can be installed, which is inconvenient. To address this issue, a more convenient microcomputer protection device is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a conveniently installed microcomputer protection device, including a mounting plate 1 installed on a wall surface. The mounting plate 1 is fixed to the wall surface with bolts to support the overall device. A support plate 3 is fixedly connected to the lower surface of the mounting plate 1. A movable plate 4 for supporting a housing 2 slides on the upper surface of the support plate 3. The housing 2 is installed on the upper surface of the movable plate 4. A voltage transformer, a current transformer, and a signal transmitter are installed inside the housing 2. After the voltage transformer and current transformer are connected to the circuit, the circuit can be detected. If the circuit is damaged, the signal transmitter will send a signal to the microcomputer processing unit to stop its operation. At the same time, a display device is also provided at the front end of the housing 2, which allows the operator to easily observe the circuit status. Since this application has not made any modifications in this part... Furthermore, since those skilled in the art can understand this part, it is not described in detail in the application document. The outer wall of the support plate 3 is provided with a fixing component 5 for fixing the movable plate 4, and the outer wall of the support plate 3 is provided with an unlocking component 6. The left and right ends of the movable plate 4 are provided with protrusions 41 near the front end to restrict the rotation of the movable plate 4. The left and right ends of the movable plate 4 are respectively rotatably connected with a set of sliders 42. The movable plate 4 and the sliders 42 are connected by a pivot. When the upper and lower surfaces of the movable plate 4 are not restricted, the movable plate 4 can rotate around the pivot. The inner wall of the support plate 3 is provided with a groove 31 for accommodating the sliders 42. The sliders 42 slide on the inner wall of the groove 31, and the protrusions 41 are inserted into the inner wall of the groove 31. When both the sliders 42 and the protrusions 41 are inside the groove 31, the movable plate 4 will be restricted and cannot rotate.

[0031] Reference Figures 2-4 The fixing component 5 includes an insert 53 for fixing the protrusion 41. The insert 53 passes through and is slidably connected to the inner wall of the slide groove 31. The insert 53 can slide left and right on the inner wall of the slide groove 31. The end of the protrusion 41 away from the moving plate 4 is provided with a slot 51 for accommodating the insert 53. The insert 53 is inserted into the inner wall of the slot 51. The insert 53 is a rectangular hollow block. When the insert 53 is inside the slot 51, the protrusion 41 will be restricted from moving back and forth. There are multiple sets of slots 51. One set of slots 51 is located at the end of the slider 42 away from the moving plate 4. When the insert 53 is inserted into the slot 51 outside the slider 42, the slider 42 will be restricted from moving back and forth. The inner wall of the insert 53 is elastically connected to the inner wall of the support plate 3 by a locking spring 55. The locking spring 55 will support the insert 53 inward at all times.

[0032] Reference Figures 2-4One end of the insert 53 away from the moving plate 4 is fixedly connected to a pull rod 54 for moving the insert 53. The pull rod 54 passes through and is slidably connected to the outer wall of the support plate 3. By pulling the pull rod 54, the insert 53 can be moved outward and disengaged from the slot 51. The left end of the pull rod 54 is fixedly connected to a lever 52 for moving the pull rod 54. The slider 42 has the same height as the protrusion 41, but the width of the slider 42 is greater than that of the protrusion 41. The opening position of the front end of the groove 31 is adapted to the shape of the protrusion 41. With this setting, the protrusion 41 can disengage from the groove 31 through the front end opening of the groove 31, while the slider 42... Because of its large size, it cannot pass through. The unlocking component 6 includes an unlocking rod 61 for squeezing the lever 52. The unlocking rod 61 is slidably connected to the outer wall of the support plate 3. The end of the lever 52 near the unlocking rod 61 is set in an inclined shape. By pulling the unlocking rod 61, the unlocking rod 61 can be driven to squeeze the inclined end of the lever 52, thus driving the lever 52 to move outward. The upper surface of the moving plate 4 is provided with mounting holes 43. The support plate 3 is set in an inverted stepped shape. When the moving plate 4 rotates downward, the inverted stepped structure at the bottom of the support plate 3 can support the moving plate 4, thus limiting the rotation angle of the moving plate 4.

[0033] Working principle: When a new line needs to be installed, first pull the unlocking lever 61. Since the end of the toggle block 52 near the unlocking lever 61 is set at an angle, when the unlocking lever 61 slides, it will press the angled end of the toggle block 52, causing the toggle block 52 to move outward. The toggle block 52 is fixedly connected to the pull rod 54, so the pull rod 54 will move outward together with the toggle block 52, thereby pulling the insert block 53 out of the slot 51 on the protrusion 41, thus unlocking the movable plate 4.

[0034] After unlocking, pull the movable plate 4 forward. The sliders 42 at both ends of the movable plate 4 slide within the grooves 31 on the inner wall of the support plate 3, while the protrusions 41 also slide within the grooves 31. When the slider 42 moves to its most movable foremost position, the protrusions 41 are now freed from the grooves 31, allowing the unlocking lever 61 to be released. At this point, the locking spring 55 pushes the insert 53 to insert into the slot 51 on the outside of the slider 42, thus fixing the slider 42 and preventing it from moving freely. Since the movable plate 4 and the slider 42 are connected by a pivot, the movable plate 4 can be rotated to a vertical position. At this time, the back of the housing 2 mounted on the upper surface of the movable plate 4 is exposed upwards, facilitating the installation of new wiring at the wiring connection ports on the back of the housing 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
