Description

Technical Field

[0001] The utility model relates to the technical field of relay protection, in particular to a relay protection alarm device. Background Art

[0002] Relay protection is a technical measure to monitor, control and protect against faults or abnormal operation in the power system. Relay protection devices can quickly and accurately detect faults in the power system, such as short circuits, ground faults, overloads, etc., and issue trip commands in a timely manner to cut off the faulty part from the system to ensure the safe and stable operation of the power system and reduce damage to equipment and systems caused by faults.

[0003] Currently, the installation method of the relay protection alarm device is usually to fix it with multiple bolts. When the internal components need to be dismantled and installed for maintenance and replacement, the bolts need to be removed one by one, which is cumbersome and affects the maintenance efficiency. Therefore, to address the above problems, we propose a new type of relay protection alarm device. Utility Model Content

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] See also Figure 1-4 The utility model provides a technical solution: a relay protection alarm device, including a protective shell 2, a slot 23 is provided on the rear surface of the protective shell 2 near the middle, the inner surface wall of the slot 23 is plugged into the plug block 11, and the outer surfaces of both sides of the plug block 11 are provided with a card slot 13, and the bottom of the protective shell 2 near both sides are symmetrically provided with movable slots 3, the two movable slots 3 are connected to the slot 23, a spring 31 is provided between the inner surface walls of the movable slot 3, the card block 33 and the card slot 13 are card-engaged, and a pull rod 32 is provided inside the spring 31, and the outer surfaces of the two pull rods 32 movably penetrate the outer surfaces of both sides of the protective shell 2 and extend to the outside.

[0023] like Figure 3 and Figure 4 As shown, one end of the spring 31 is fixedly connected to the block 33, and the other end of the spring 31 is fixedly connected to the inner surface of the movable groove 3. One end of the spring 31 is fixed, and the other end is fixed to the block 33. Such an arrangement allows the block 33 to contract inside the movable groove 3 when it is squeezed by the insert block 11, and to rebound when the squeezing force is gone.

[0024] like Figure 1-Figure 4As shown, one end of the pull rod 32 is fixedly connected to the outer surface of one side of the block 33, and the rear surface of the plug-in block 11 is fixedly connected to the base 1. The pull rod 32 is fixed to the block 33 so that the block 33 can be disengaged from the slot 13 on the plug-in block 11 by pulling the pull rod 32 during disassembly, thereby releasing the locking relationship between the plug-in block 11 and the protective shell 2, and the base 1 is conveniently fixed.

[0025] like Figure 1-Figure 4 As shown, a relay protector body 22 is provided inside the protective shell 2, and multiple heat dissipation grooves 21 are provided on the outer surfaces of both sides of the protective shell 2. The relay protector body 22 is designed inside the protective shell 2 to better protect the internal electrical components and increase the service life. A transparent protective screen is provided on the front surface of the relay protector body 22 to facilitate observation of internal indicators, and the heat dissipation grooves 21 play a role in dissipating heat.

[0026] like Figure 1 and Figure 2 As shown, a mounting base 4 is installed on the top of the protective shell 2, and an audible and visual alarm 41 is fixedly connected to the top of the mounting base 4 near the front side. The mounting base 4 is convenient for installing the audible and visual alarm 41. When the relay protector body 22 detects a fault, it can emit a loud alarm and a striking flashing light. The sound can attract the attention of nearby people, and the light can also play an obvious warning role in noisy environments or dimly lit places.

[0027] like Figure 1 and Figure 4 As shown, a protective seat 42 is fixedly connected to the top of the mounting base 4 near the rear side. The position of the protective seat 42 corresponds to the position of the sound and light alarm 41. The protective seat 42 is to further protect the sound and light alarm 41 and can increase its life to a certain extent in harsh outdoor environments.

[0028] like Figure 1-Figure 4 As shown, the other ends of the two pull rods 32 are fixedly connected to handles 34, and the front surface of the base 1 is provided with a rubber pad 12. The front surface of the rubber pad 12 fits with the rear surface of the protective shell 2. The handle 34 is for the operator to pull the pull rod 32 conveniently, and the rubber pad 12 is for reducing the vibration during the installation of the protective shell 2 and the base 1, so as to better protect the relay protector body 22 inside the protective shell 2.

[0029] The method of use and working principle of this device: When the device needs to be maintained and disassembled, the user can easily operate it by hand, pull the handles 34 on both sides of the protective shell, which will drive the pull rod 32 to move smoothly to both sides, thereby causing the block 33 in the movable groove 3 to slide outward, away from the original slot 13 position. As the block 33 is released, the locking state between the plug 11 and the protective shell 2 is released, allowing the protective shell 2 and the relay protector body 22 inside it to be easily separated from the base 1. Conversely, during the reinstallation process, the user only needs to align the protective shell 2 with the plug 11 on the base 1 and slowly insert the slot 23. As the insertion action proceeds, the plug 11 will naturally squeeze the block 33. Under the elastic action of the built-in spring 31, the block 33 will adaptively shrink inside the movable slot 3. Since one side of the block 33 is firmly connected to the pull rod 32, The pull rod 32 can flexibly pass through the protective shell 2, and the block 33 will shrink smoothly along a straight line. As the slot 23 goes deeper, when the inclined surface of the block 33 is aligned with the position of the slot 13, the elastic force of the spring 31 is quickly restored, pushing the block 33 to rebound and accurately snap into the slot 13, forming a firm snap connection. This process not only ensures the stable installation of the protective shell 2 and its internal components on the base 1, but also greatly simplifies the disassembly and assembly process through the clever buckle design, making the entire plug-in and unplug process fast and able to meet the needs of quick installation and disassembly. During the use of this device, when the relay protector body 22 detects a circuit fault, it can emit a loud alarm and a striking flashing light. The sound can attract the attention of nearby people, and the light can also play an obvious warning role in noisy environments or dimly lit places, reminding the staff in time.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
