[0002] A smart substation is a substation that uses advanced, reliable, integrated and environmentally friendly intelligent equipment, with full-station information digitization, communication platform networking, and information sharing standardization as basic requirements. It automatically completes basic functions such as information collection, measurement, control, protection, metering and detection. At the same time, it has advanced functions such as supporting real-time automatic control of the power grid, intelligent regulation, online analysis and decision-making, and collaborative interaction.

[0003] Since some smart substations are installed near roads, there will be many pedestrians passing by nearby, and fences are needed to isolate the smart substations to prevent people or large animals from approaching. However, the existing isolation fences have a single function and do not have a buffering function. When accidentally hit by a vehicle, they will suffer greater damage. Moreover, the existing isolation fences do not have the function of autonomously driving away approaching people or large animals, and the safety is not high enough. Therefore, in view of the above situation, it is urgent to develop an on-site protection device for smart substations that is convenient for isolation and has a buffering function to reduce the damage caused by accidental collisions, and has a monitoring alarm function that can automatically alarm and drive away approaching people or large animals, so as to overcome the shortcomings in current practical applications and meet current needs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A local protection device for a smart substation comprises a protective fence, an anti-collision mechanism, a circular track and a warning mechanism. An anti-collision mechanism is installed on each of the four sides of the protective fence. The anti-collision mechanism comprises: an arc-shaped protective plate, a limit guide rod and a spring. A plurality of limit guide rods are fixed to the rear side of the arc-shaped protective plate. The limit guide rods penetrate the protective fence and are slidably connected to the protective fence. A spring is installed on the outer side of each limit guide rod. An circular track is fixed on the top of the protective fence. A warning mechanism is installed on the circular track. The warning mechanism comprises: a support plate, a transmission shaft, a roller, a gear, a drive motor, a camera and a buzzer alarm. The support plate is located above the circular track. Two transmission shafts are rotatably connected to the support plate. Each transmission shaft is equipped with a gear, and the two gears are meshed with each other. A roller is fixed to the bottom of each transmission shaft. The two rollers are respectively inserted into the inner and outer sides of the circular track. A drive motor is fixed on the support plate. The output shaft of the drive motor is connected to the transmission shaft. A camera and a buzzer alarm are installed on the support plate.

[0007] Preferably, the outer side of the roller is provided with anti-slip grooves.

[0008] Preferably, both inner and outer sides of the annular track are provided with sliding grooves for the rollers to move.

[0010] Preferably, a plurality of mounting feet are fixed to the bottom of the protective fence, and each of the mounting feet is provided with a plurality of mounting holes.

[0011] The beneficial effects of the utility model are as follows: the on-site protection device of the smart substation, when in use, isolates the smart substation from the outside world through a protective fence to prevent people or large animals from approaching. When encountering an accidental collision with a vehicle, the impact force is transmitted to the buffer pad and the arc-shaped protective plate, and the impact is buffered and absorbed by the elastic deformation of the buffer pad. At the same time, the arc-shaped protective plate drives the spring to deform, and the impact force is buffered and absorbed by the spring to reduce the damage caused by the collision; the drive shaft and the roller are driven to rotate by the driving motor, and the support plate is driven to move along the circular track by the rotation of the roller, and the camera and the buzzer alarm are driven to move along the circular track by the support plate, thereby expanding the monitoring range of the camera. When the camera monitors that a person or a large animal is too close to the protective fence, the buzzer alarm emits an alarm sound to alarm and drive away the person or large animal. In summary, the utility model is convenient for isolation and has a buffer function, which can reduce the damage caused by accidental collisions; it has a monitoring alarm function, and can automatically alarm and drive away approaching people or large animals.

[0018] 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 of 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.

[0019] Specific examples are given below.

[0020] See also Figure 1 to Figure 4In the embodiment of the utility model, a local protection device for a smart substation includes a protective fence 1, an anti-collision mechanism 3, a circular track 4, a warning mechanism 5 and a smart substation 6. A plurality of mounting legs 2 are fixed to the bottom of the protective fence 1, and a plurality of mounting holes 201 are provided on each mounting leg 2. During installation, bolts are passed through the mounting holes 201 and fixed to the ground, thereby fixing the mounting legs 2 and the protective fence 1 to the ground. An anti-collision mechanism 3 is installed on the four sides of the protective fence 1. A circular track 4 is fixed to the top of the protective fence 1, and a warning mechanism 5 is installed on the circular track 4. A smart substation 6 is installed on the inner side of the protective fence 1 on the ground. During use, the smart substation 6 is isolated from the outside world by the protective fence 1 to prevent people or large animals from approaching. When a vehicle is accidentally hit, the anti-collision mechanism 3 absorbs and buffers the impact force, thereby improving the protection performance. The warning mechanism 5 monitors the surroundings of the protective fence 1. When a person or large animal is too close, the warning mechanism 5 emits an alarm sound to alarm and drive the person or large animal away.

[0021] The anti-collision mechanism 3 includes: an arc-shaped protective plate 301, a limiting guide rod 302 and a spring 303. A plurality of limiting guide rods 302 are fixed to the rear side of the arc-shaped protective plate 301. The limiting guide rods 302 penetrate the protective fence 1. The limiting guide rods 302 are slidably connected to the protective fence 1. A spring 303 is installed on the outer side of each limiting guide rod 302. A buffer pad 3011 is fixed to the front side of the arc-shaped protective plate 301. The buffer pad 3011 is made of rubber to give it a certain elasticity. When encountering a collision, the impact force is transmitted to the buffer On the pad 3011 and the arc-shaped protective plate 301, the elastic deformation of the buffer pad 301 is used to buffer and absorb the impact. At the same time, the arc-shaped protective plate 301 drives the spring 303 to deform, and the spring 303 buffers and absorbs the impact force, thereby improving the protection. In addition, the arc-shaped design of the arc-shaped protective plate 301 is more likely to produce relative sliding when impacted, which facilitates relative sliding between the impacting object and the arc-shaped protective plate 301, thereby converting the direct impact force into sliding force to consume part of it, thereby reducing the impact.

[0022] The warning mechanism 5 includes: a support plate 501, a transmission shaft 502, a roller 503, a gear 504, a drive motor 505, a camera 506 and a buzzer alarm 507. The support plate 501 is located above the circular track 4. Two transmission shafts 502 are rotatably connected to the support plate 501. A gear 504 is installed on each transmission shaft 502. The two gears 504 are meshed with each other. A roller 503 is fixed to the bottom of each transmission shaft 502. The two rollers 503 are respectively inserted into the inner and outer sides of the circular track 4. The inner and outer sides of the circular track 4 are provided with a slide groove 401 for the movement of the roller 503. The outer side of the roller 503 is provided with an anti-slip pattern 5031. A driving motor 505 is fixed, and the output shaft of the driving motor 505 is connected to the transmission shaft 502. A camera 506 and a buzzer alarm 507 are installed on the support plate 501. When in use, the driving motor 505 drives the transmission shaft 502 and the roller 503 to rotate, and the rotation of the roller 503 drives the support plate 501 to move along the circular track 4, and the support plate 501 drives the camera 506 and the buzzer alarm 507 to move along the circular track 4, thereby expanding the monitoring range of the camera 506. When the camera 506 monitors that a person or a large animal is too close to the protective fence 1 (within two meters), the buzzer alarm 507 emits an alarm sound to warn and drive away the person or large animal.

[0023] Working principle: When the smart substation local protection device is used, the smart substation 6 is isolated from the outside world by the protective fence 1 to prevent people or large animals from approaching. When encountering an accidental collision with a vehicle, the impact force is transmitted to the buffer pad 3011 and the arc-shaped protective plate 301, and the impact is buffered and absorbed by the elastic deformation of the buffer pad 3011. At the same time, the arc-shaped protective plate 301 drives the spring 303 to deform, and the impact force is buffered and absorbed by the spring 303 to reduce the damage caused by the collision; the drive motor 505 drives the transmission shaft 502 and the roller 503 to rotate, and the support plate 501 is driven to move along the circular track 4 through the rotation of the roller 503, and the camera 506 and the buzzer alarm 507 are driven to move along the circular track 4 through the support plate 501, thereby expanding the monitoring range of the camera 506. When the camera 506 monitors that a person or a large animal is too close to the protective fence 1, the buzzer alarm 507 emits an alarm sound to alarm and drive the person or large animal away.
