[0002] A current limiting protection device is a safety device used to control the flow of current in a circuit. It can take quick action when it detects abnormal current (such as overload or short circuit) to protect the circuit from damage. These devices usually have multiple protection functions, including short circuit protection, overload protection, over-voltage and under-voltage protection, cable temperature monitoring, leakage current monitoring, etc., and can transmit fault information to the monitoring system through the communication interface to achieve remote monitoring.

[0003] In the process of laying the circuit, a current limiting protection device is needed to protect the circuit from damage. The currently available current limiting protection devices have the advantage of being easy to install.

[0004] However, the currently available current limiting protection devices are mostly installed in external environments and do not have a storage and protection structure, so the device body is affected by external factors for a long time, and is prone to damage or cannot operate stably. The safety is poor. Therefore, an energy-saving current limiting protection device is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an energy-saving current limiting protection device, comprising a current limiting protection device body and a box body, wherein a storage protection structure is arranged outside the current limiting protection device body;

[0007] The storage protection structure includes two sets of linear guide rails fixedly connected to the back of the box body, a slider is slidably connected to the inner side of the linear guide rail, a movable plate is fixedly connected to the front of the slider, a handle is fixedly connected to the top of the movable plate, a mounting frame is fixedly connected to the bottom of the movable plate, a positioning sleeve is fixedly connected to the bottom of the current limiting protection device body, and a positioning rod is fixedly connected to the inner bottom wall of the box body.

[0008] Furthermore, the current limiting protection device body is fixedly mounted on the inner side of the mounting frame, and the positioning rod is plugged into the positioning sleeve.

[0009] Furthermore, cooling fans are installed on the left and right sides of the box body, and a dustproof net is fixedly connected to the inner side of the cooling fan.

[0010] Furthermore, a heat dissipation port is provided on the front side of the box body, and an isolation net is fixedly connected to the inner side of the heat dissipation port.

[0011] Furthermore, an observation window is fixedly connected to the front of the box body, and the observation window is explosion-proof glass.

[0013] Furthermore, a wire passing hole is provided at the bottom of the box body, and a rubber insulating sleeve is bonded to the inner side of the wire passing hole.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The energy-saving current-limiting protection device realizes the function of storing and protecting the current-limiting protection device body by setting a storage protection structure, thereby preventing the current-limiting protection device body from being affected by external factors for a long time, and then being easily damaged or unable to operate stably. The device has good safety and is easy to be taken out from the inside of the box body, so it is convenient to use in practice.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , an energy-saving current limiting protection device in this embodiment includes a current limiting protection device body 1 and a box body 2, and a storage protection structure is arranged outside the current limiting protection device body 1;

[0023] The storage and protection structure includes two sets of linear guide rails 3 fixedly connected to the back of the box body 2, a slider 4 is slidably connected to the inner side of the linear guide rail 3, a moving plate 5 is fixedly connected to the front of the slider 4, a handle 6 is fixedly connected to the top of the moving plate 5, a mounting frame 7 is fixedly connected to the bottom of the moving plate 5, a positioning sleeve 8 is fixedly connected to the bottom of the current limiting protection device body 1, and a positioning rod 9 is fixedly connected to the inner bottom wall of the box body 2. By setting up the storage and protection structure, the function of storing and protecting the current limiting protection device body 1 is realized, thereby preventing the current limiting protection device body 1 from being affected by external factors for a long time, which is prone to damage or cannot run stably. It has good safety and is easy to be taken out from the inside of the box body 2, so it is more convenient to use in practice.

[0024] Among them, when it is necessary to use or adjust the current limiting protection device body 1, the staff only needs to hold the handle 6 and pull it upwards to lift the movable plate 5, so that the slider 4 slides upward on the inside of the linear guide rail 3. At the same time, the positioning rod 9 and the positioning sleeve 8 are released from the connection, and then the current limiting protection device body 1 is directly pulled out to the outside of the box body 2 through the mounting frame 7 for use or adjustment.

[0025] In addition, after the current limiting protection device body 1 is used or adjusted, the staff only needs to hold the handle 6 and push it downward to lower the movable plate 5, so that the slider 4 slides downward on the inside of the linear guide rail 3. At the same time, the positioning rod 9 is inserted into the positioning sleeve 8 to the inside for positioning, and then the current limiting protection device body 1 is directly pushed back to the inside of the box body 2 through the mounting frame 7 for storage protection, thereby avoiding the influence of external factors and ensuring the normal operation of the current limiting protection device body 1.

[0026] It should be noted that the current limiting protection device body 1 is fixedly mounted on the inner side of the mounting frame 7 , and the positioning rod 9 is plugged into the positioning sleeve 8 .

[0027] Among them, cooling fans 10 are installed on the left and right sides of the box body 2, and a dustproof net 11 is fixedly connected to the inner side of the cooling fan 10. A heat dissipation port 12 is opened on the front of the box body 2, and an isolation net 13 is fixedly connected to the inner side of the heat dissipation port 12. By arranging the cooling fan 10 and the heat dissipation port 12, the effect of ventilation and heat dissipation is achieved, and the dustproof net 11 and the isolation net 13 can filter dust and debris, thereby preventing dust and debris from affecting the current limiting protection device body 1.

[0028] At the same time, an observation window 14 is fixedly connected to the front of the box body 2. The observation window 14 is explosion-proof glass. By setting the observation window 14, it is convenient for the staff to directly observe the circuit data displayed on the current limiting protection device body 1 from the outside of the box body 2.

[0029] It should be understood that the outer diameter of the current limiting protection device body 1 is smaller than the inner diameter of the box body 2, and the box body 2 is square.

[0030] In addition, a wire passage hole 15 is opened at the bottom of the box body 2, and a rubber insulating sleeve 16 is bonded to the inner side of the wire passage hole 15. By setting the rubber insulating sleeve 16, it has good insulation and can prevent the outer skin of the wire from rubbing against the inner side of the wire passage hole 15, thereby preventing the wire from breaking and leaking electricity.

[0031] The working principle of the above embodiment is:

[0032] When it is necessary to use or adjust the current limiting protection device body 1, the staff only needs to hold the handle 6 and pull it upwards to lift the movable plate 5, so that the slider 4 slides upward on the inner side of the linear guide rail 3. At the same time, the positioning rod 9 and the positioning sleeve 8 are released, and then the current limiting protection device body 1 is directly pulled out to the outside of the box body 2 through the mounting frame 7 for use or adjustment. When the current limiting protection device body 1 is used or adjusted, the staff only needs to hold the handle 6 and push it downwards to lower the movable plate 5, so that the slider 4 slides downward on the inner side of the linear guide rail 3. At the same time, the positioning rod 9 is inserted into the positioning sleeve 8 to the inside for positioning, and then the current limiting protection device body 1 is directly pushed back to the inside of the box body 2 through the mounting frame 7 for storage protection, thereby avoiding the influence of external factors and ensuring the normal operation of the current limiting protection device body 1.
