Description

Technical Field

[0001] The invention relates to the technical field of electric power safety, and in particular to an electric power safety monitoring warning sign. Background Art

[0002] Power safety is to ensure that electrical equipment, electrical engineering and electrical facilities are operating normally, and to prevent and reduce accidents and dangerous events by taking a series of correct preventive measures. Monitoring warning signs are commonly used monitoring and warning devices in the field of power safety.

[0003] A Chinese patent discloses an electric power safety monitoring warning sign (authorization announcement number CN219202629U). By setting up an installation box, a warning plate, a thermal infrared human body sensor, an LED lighting lamp, an alarm light, a lower clamping plate, a mounting groove and a passive infrared probe, the electric power safety monitoring warning sign has the function of automatically alarming when someone approaches. It has more practical functions and can effectively attract the attention of passers-by and reduce the occurrence rate of accidents.

[0004] Since the above-mentioned device installs the thermal infrared human body sensor and the passive infrared probe nakedly on the surfaces of the mounting box and the lower clamping plate respectively, when dust or rain falls on the surfaces of the thermal infrared human body sensor and the passive infrared probe, the dust or rain can easily cover and block the detection ends of the thermal infrared human body sensor and the passive infrared probe. The dust or rain can absorb, scatter and block the infrared radiation emitted by the thermal infrared human body sensor and the passive infrared probe, which will increase the detection difficulty of the thermal infrared human body sensor and the passive infrared probe, and further increase the detection error of the thermal infrared human body sensor and the passive infrared probe. Summary of the invention

[0005] Based on this, it is necessary to provide a power safety monitoring warning sign to address the problem that the existing power safety monitoring warning sign with personnel approach detection function is easily covered and blocked by dust or rain, and adds thermal infrared human body sensors and passive infrared probes for detection errors.

[0006] A power safety monitoring warning sign comprises a power warning sign, two bolt clamps, a controller and an audible and visual alarm, wherein the two bolt clamps are respectively fixedly connected to the top and bottom ends of the power warning sign, the controller is installed inside the power warning sign, the audible and visual alarm is fixedly connected to the surface of the power warning sign, and a personnel monitoring device distributed in a ring shape is fixedly connected to the surface of the bolt clamps below.

[0007] Furthermore, the personnel monitoring device includes a mounting frame, an infrared human body sensor, a transparent protective cover, evenly distributed air guide blades, a connecting rod and a sponge cleaning cover, the mounting frame is fixedly connected to the surface of the bolt clamp below, the infrared human body sensor is embedded in the surface of the mounting frame, the transparent protective cover is rotatably connected to the surface of the mounting frame, the infrared human body sensor is arranged inside the transparent protective cover, the air guide blades are annularly fixedly connected to the surface of the transparent protective cover, the angle between the air guide blades and the horizontal plane is forty-five degrees, the connecting rod is fixedly connected to the surface of the mounting frame, the sponge cleaning cover is rotatably connected to the surface of the connecting rod, the surface of the sponge cleaning cover is in contact with the surface of the transparent protective cover, and an air guide channel is opened on the surface of the connecting rod, the upper opening of the air guide channel faces the air guide blades, and the lower opening of the air guide channel is arranged on the inner side of the sponge cleaning cover.

[0008] In one of the embodiments, the transparent protective cover can separate the infrared human body sensor from the outside world, so that it can operate in a clean environment. At the same time, the wind guide blades can use the kinetic energy of wind energy and falling rain to actively drive the transparent protective cover to rotate, so that the sponge cleaning cover can clean the rotating transparent protective cover to ensure the cleanliness of the inside of the detection range of the infrared human body sensor, thereby improving the detection accuracy of the infrared human body sensor; the wind guide blades can stir the surrounding air and guide it to the surroundings during the rotation process, which can not only blow the surface of the transparent protective cover to improve the cleaning effect of the surface of the transparent protective cover, but also the airflow entering the inside of the air guide hopper can be swept from the inside to the outside of the sponge cleaning cover, which will not make dust or rainwater penetrate deeper into the inside of the sponge cleaning cover, thereby improving the cleaning and drying effect of the sponge cleaning cover, and at the same time, because the airflow is blowing away from the transparent protective cover, this can also prevent dust or rainwater from adhering to the surface of the transparent protective cover for the second time, further ensuring the cleaning effect of the transparent protective cover, and further improving the detection accuracy of the infrared human body sensor.

[0009] Furthermore, the lower opening of the air guiding channel faces away from the sponge cleaning cover, and the height of the lower opening of the air guiding channel is the same as the height of the sponge cleaning cover.

[0010] In one of the embodiments, this can prevent dust or rain from adhering to the surface of the transparent protective cover for a second time, further ensuring the cleaning effect of the transparent protective cover, and further improving the detection accuracy of the infrared human body sensor.

[0011] Furthermore, the lower opening of the air guide channel is arranged on one side of the axial center line of the sponge cleaning sleeve.

[0012] In one embodiment, this can reduce the effect of airflow on the rotation of the sponge cleaning sleeve, so as to ensure that the transparent protective cover can easily drive the sponge cleaning sleeve to rotate.

[0013] Furthermore, both ends of the top and bottom of the sponge cleaning sleeve are fixedly connected with a rotating sleeve, and the rotating sleeve is rotatably connected to the surface of the connecting rod.

[0015] Furthermore, reinforcing columns distributed in a ring shape are fixedly connected between the two rotating sleeves, and the reinforcing columns are embedded and installed inside the sponge cleaning sleeve.

[0016] In one of the embodiments, this can make the sponge cleaning cover more rigid, prevent the sponge cleaning cover from being deformed by airflow, and improve the stability of the sponge cleaning cover during operation.

[0017] Furthermore, an air guide scoop is fixedly connected to the surface of the connecting rod, and the air guide scoop is arranged between the air guide blades and the upper opening of the air guide channel.

[0018] In one embodiment, this can direct more airflow into the air guide channel to increase the amount of blowing on the sponge cleaning cover.

[0019] Furthermore, a ring groove is provided on the surface of the mounting frame, a rotating ring fixedly connected to the transparent protective cover is rotatably connected inside the ring groove, and a ball contacting the ring groove is embedded on the surface of the rotating ring.

[0020] In one embodiment, the ring groove cooperates with the rotating ring to limit the position of the transparent protective cover, and the ball bearing can reduce the friction of the rotating ring, thereby reducing the rotation resistance of the transparent protective cover.

[0021] Furthermore, a water guide port is provided on the top of the mounting frame, and the water guide port is arranged directly above the wind guide blade.

[0022] In one embodiment, this can utilize the falling water to impact the wind guide blades to drive the transparent protective cover to rotate, so as to increase the probability of the transparent protective cover rotating and cleaning.

[0023] Furthermore, a filter screen is embedded in the water outlet, and the top of the filter screen is flush with the upper opening of the water outlet.

[0024] In one of the embodiments, this can filter impurities in the water and prevent the impurities from adhering to the surface of the air guide blades, thereby reducing the burden on the rotation of the air guide blades.

[0025] Furthermore, the cross-sectional shape of the top of the mounting frame is sloped, and the upper opening of the water guide port is arranged at the lowest point of the top of the mounting frame.

[0026] In one embodiment, this can direct more water to impact the wind guide blades, further increasing the probability of the transparent protective cover rotating to clean.

[0027] In the above-mentioned electric power safety monitoring warning sign, the transparent protective cover can separate the infrared human body sensor from the outside world, so that it can operate in a clean environment. At the same time, the wind guide blade can use the kinetic energy of wind energy and falling rain to actively drive the transparent protective cover to rotate, so that the sponge cleaning cover can clean the rotating transparent protective cover to ensure the cleanliness of the inside of the detection range of the infrared human body sensor, thereby improving the detection accuracy of the infrared human body sensor;

[0028] The air guide blades can stir the surrounding air and guide it in all directions during the rotation process, which can not only blow the surface of the transparent protective cover to improve the cleaning effect of the transparent protective cover surface, but also the airflow entering the air guide bucket can be swept from the inside to the outside of the sponge cleaning cover, which will not make dust or rainwater penetrate deeper into the sponge cleaning cover, thereby improving the cleaning and drying effect of the sponge cleaning cover. At the same time, since the airflow is blowing away the transparent protective cover, this can also prevent dust or rainwater from adhering to the surface of the transparent protective cover for the second time, further ensuring the cleaning effect of the transparent protective cover and further improving the detection accuracy of the infrared human body sensor.

The term "and / or" used in the specification of the present invention includes any and all combinations of one or more related listed items.

[0045] Combine the following Figure 1 - Figure 8 The invention describes the electric power safety monitoring warning sign.

[0046] In one embodiment, an electric safety monitoring warning sign includes an electric warning sign 100, two bolt clamps 200, a controller 300 and an audible and visual alarm 400, wherein the two bolt clamps 200 are respectively fixedly connected to the top and bottom ends of the electric warning sign 100, the controller 300 is installed inside the electric warning sign 100, the audible and visual alarm 400 is fixedly connected to the surface of the electric warning sign 100, and a personnel monitoring device 500 distributed in a ring shape is fixedly connected to the surface of the lower bolt clamp 200;

[0047] The staff first sets and fixes the two bolt clamps 200 on the corresponding positions of the electric pole, and then matches and connects the external power supply with the controller 300, the sound and light alarm 400 and the infrared human body sensor 502;

[0048] Since the infrared human body sensors 502 are distributed in a ring shape on the surface of the utility pole, all the infrared human body sensors 502 can monitor whether there is a person within the specified range of the utility pole in a 360-degree manner. When the infrared human body sensors 502 detect the presence of a person, the infrared human body sensors 502 transmit a corresponding signal to the controller 300. The controller 300 controls the sound and light alarm 400 to turn on according to a preset alarm instruction matching the signal. The sound and light alarm 400 emits an alarm sound and an alarm light and cooperates with the warning slogan on the power warning sign 100 to warn people approaching the utility pole.

[0049] like Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the personnel monitoring device 500 includes a mounting frame 501, an infrared human body sensor 502, a transparent protective cover 503, evenly distributed air guide blades 504, a connecting rod 505 and a sponge cleaning sleeve 506. The mounting frame 501 is fixedly connected to the surface of the lower bolt clamp 200, the infrared human body sensor 502 is embedded and installed on the surface of the mounting frame 501, the transparent protective cover 503 is rotatably connected to the surface of the mounting frame 501, the infrared human body sensor 502 is arranged inside the transparent protective cover 503, the air guide blades 504 are annularly fixedly connected to the surface of the transparent protective cover 503, the angle between the air guide blades 504 and the horizontal plane is forty-five degrees, and the connecting rod 505 is connected to the surface of the transparent protective cover 503. 05 is fixedly connected to the surface of the mounting frame 501, the sponge cleaning cover 506 is rotatably connected to the surface of the connecting rod 505, the surface of the sponge cleaning cover 506 contacts the surface of the transparent protective cover 503, and an air guide channel 5051 is opened on the surface of the connecting rod 505, the upper opening of the air guide channel 5051 faces the air guide blade 504, and the lower opening of the air guide channel 5051 is arranged on the inner side of the sponge cleaning cover 506; the lower opening of the air guide channel 5051 faces away from the sponge cleaning cover 506, and the height of the lower opening of the air guide channel 5051 is the same as that of the sponge cleaning cover 506; the lower opening of the air guide channel 5051 is arranged on one side of the axis of the sponge cleaning cover 506;

[0050] The top and bottom ends of the sponge cleaning sleeve 506 are fixedly connected with a rotating sleeve 507, and the rotating sleeve 507 is rotatably connected to the surface of the connecting rod 505, which can prevent the sponge cleaning sleeve 506 from moving, so as to ensure that the sponge cleaning sleeve 506 can clean the transparent protective cover 503 in the designated area; a ring-shaped reinforcement column 508 is fixedly connected between the two rotating sleeves 507, and the reinforcement column 508 is embedded and installed inside the sponge cleaning sleeve 506, which can make the sponge cleaning sleeve 506 more firm and prevent the sponge cleaning sleeve 506 from being deformed by airflow, so as to improve the stability of the operation of the sponge cleaning sleeve 506; the surface of the connecting rod 505 is fixedly connected with an air guide scoop 509, which 509 is arranged between the air guide blade 504 and the upper opening of the air guide channel 5051, which can guide more airflow into the air guide channel 5051 to increase the amount of blowing on the sponge cleaning sleeve 506; the surface of the mounting frame 501 is provided with an annular groove 5011, and a rotating ring 510 fixedly connected to the transparent protective cover 503 is rotatably connected inside the annular groove 5011, and a ball 511 in contact with the annular groove 5011 is embedded and installed on the surface of the rotating ring 510. The annular groove 5011 cooperates with the rotating ring 510 to limit the position of the transparent protective cover 503, and the ball 511 can reduce the friction of the rotating ring 510, thereby reducing the rotation resistance of the transparent protective cover 503;

[0051] During the normal operation of the infrared human body sensor 502, the transparent protective cover 503 cooperates with the mounting frame 501 to isolate the detection end of the infrared human body sensor 502 from the outside world, thereby preventing dust or water from entering the detection end of the infrared human body sensor 502, so as to ensure that the infrared human body sensor 502 can operate normally.

[0052] When wind blows over the surface of the transparent protective cover 503, the wind can directly blow away the loosely adhered dust or rainwater on the surface of the transparent protective cover 503, making the transparent protective cover 503 cleaner, thereby reducing the impact on the normal detection of the infrared human body sensor 502;

[0053] When wind blows through the wind guide blades 504, the wind guide blades 504 can block the wind from passing through. When the thrust of the wind is greater than the resistance of the wind guide blades 504 driving the transparent protective cover 503, the rotating ring 510 and the ball 511 to rotate along the annular groove 5011, the wind drives the transparent protective cover 503, the rotating ring 510 and the ball 511 to rotate along the annular groove 5011 through the wind guide blades 504. The transparent protective cover 503 drives the dust or rainwater adhered to its surface to rotate. At this time, the sponge cleaning cover 506 rotates to adhere to dust and absorb rainwater under the action of the rotating friction of the transparent protective cover 503, which can make the surface of the transparent protective cover 503 cleaner, further reducing the impact on the normal detection of the infrared human body sensor 502.

[0054] In the process of the air guide blade 504 driving the transparent protective cover 503 to rotate, the air guide blade 504 rotates to stir the surrounding airflow and guide it in all directions. When the horizontal airflow passes through the air guide scoop 509, the horizontal airflow passes through the air guide scoop 509 and the air guide channel 5051 in sequence to blow the inner side of the sponge cleaning cover 506 from the direction facing away from the transparent protective cover 503. Since the horizontal airflow blows the sponge cleaning cover 506 from the inside to the outside, the rainwater absorbed by the inside of the sponge cleaning cover 506 and the dust adhered to the surface of the sponge cleaning cover 506 can be blown out of the sponge cleaning cover 506. External blowing will not cause dust or rainwater to penetrate deeper into the sponge cleaning cover 506, thereby improving the cleaning and drying effect of the sponge cleaning cover 506. At the same time, since the horizontal airflow is blowing towards the back of the transparent protective cover 503, this can also prevent dust or rainwater from adhering to the surface of the transparent protective cover 503 for a second time, further ensuring the cleaning effect of the transparent protective cover 503. At the same time, the vertical airflow can also play a role in blowing the surface of the transparent protective cover 503, further improving the cleaning effect of the surface of the transparent protective cover 503.

[0055] like Figure 3 , Figure 4 and Figure 5As shown, a water inlet 5012 is provided at the top of the mounting frame 501, and the water inlet 5012 is arranged just above the wind guide blade 504, which can utilize the falling water to impact the wind guide blade 504 to drive the transparent protective cover 503 to rotate, so as to increase the probability of the transparent protective cover 503 rotating and cleaning; a filter net 512 is embedded and installed inside the water inlet 5012, and the top of the filter net 512 is flush with the upper opening of the water inlet 5012, which can filter impurities in the water and prevent the impurities from adhering to the surface of the wind guide blade 504, thereby reducing the burden of the wind guide blade 504 rotating; the cross-sectional shape of the top of the mounting frame 501 is sloped, and the upper opening of the water inlet 5012 is arranged at the lowest point of the top of the mounting frame 501, which can guide more water to impact the wind guide blade 504, further increasing the probability of the transparent protective cover 503 rotating and cleaning;

[0056] When rainwater slides downward along the top of the mounting frame 501, the mounting frame 501 can guide the rainwater into the water guide port 5012. After falling along the water guide port 5012, the rainwater can impact the wind guide blade 504 directly below. When the impact force of the rainwater is greater than the resistance of the wind guide blade 504 when driving the transparent protective cover 503, the rotating ring 510 and the ball 511 to rotate along the annular groove 5011, the wind guide blade 504 drives the transparent protective cover 503, the rotating ring 510 and the ball 511 to rotate along the annular groove 5011 under the impact of the rainwater. The transparent protective cover 503 drives the dust or rainwater adhered to its surface to rotate. At this time, the sponge cleaning cover 506 rotates to adhere to dust and absorb rainwater under the action of the rotating friction of the transparent protective cover 503, which can make the surface of the transparent protective cover 503 cleaner and further reduce the impact on the normal detection of the infrared human body sensor 502.

[0057] It should be noted that the power warning sign 100, bolt clamp 200, controller 300, sound and light alarm 400 and infrared human body sensor 502 in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the controller 300, sound and light alarm 400 and infrared human body sensor 502 are powered by AC power, which will not be elaborated here.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
