Therefore, electrical safety monitoring devices are needed to perform real-time detection of the current, voltage and other operating conditions of electrical equipment.

[0003] When the existing electrical safety monitoring device is in use, when a fire occurs in external electrical equipment, since the fire is small at the beginning and the smoke is also small, it takes too long for the smoke to drift into the detection equipment and trigger the alarm. As a result, the alarm can only be sounded when the electrical equipment is burned and the loss is large. The alarm cannot be sounded quickly when the fire just occurs and the smoke is small, resulting in large losses. Utility Model Content

[0033] 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.

[0034] In order to achieve the above-mentioned purpose of the invention, the utility model provides an electrical safety monitoring device, including a safety monitoring cabinet 2 and an electrical equipment monitoring ammeter 10 arranged inside the safety monitoring cabinet 2; an electrical equipment monitoring voltmeter 11 is arranged below the electrical equipment monitoring ammeter 10, and a support plate 8 is arranged below the electrical equipment monitoring voltmeter 11; mounting ears 1 are arranged at the four corners of the back plate of the safety monitoring cabinet 2; the induced draft fan 9 and the electrical equipment monitoring smoke alarm 12 are electrically connected to an external power supply, a cabinet door 5 is arranged at the front opening of the safety monitoring cabinet 2, and a visual window 3 is embedded in the surface of the cabinet door 5, and an indicator light 4 is arranged below the visual window 3;

[0035] When in use, firstly, the mounting ears 1 are provided at the four corners of the back plate, and the bolts are inserted into the external mounting parts for installation, so that the device is installed near the electrical equipment to be detected, and then the cabinet door 5 is opened. At this time, the external electrical equipment can be connected to the electrical equipment monitoring ammeter 10 and the electrical equipment monitoring voltmeter 11 inside the safety monitoring cabinet 2 through the power line, so that the electrical equipment monitoring ammeter 10 and the electrical equipment monitoring voltmeter 11 can monitor the voltage and current of the electrical equipment at any time;

[0036] In this technical solution, preferably

[0037] An induced draft fan 9 is provided on the support plate 8; an electrical equipment monitoring smoke alarm 12 is provided below the support plate 8, and a ventilation hole 6 is provided on the cabinet door 5 below the indicator light 4. When working, the induced draft fan 9 starts to work, generates wind adsorption, and sucks the external gas into the interior of the safety monitoring cabinet 2 through the ventilation hole 6, cools the internal electrical equipment to avoid malfunctions caused by excessive temperature, and the wind adsorption generated by the induced draft fan 9 can continuously generate suction for the external gas, so that if the external electrical equipment fails and catches fire, the external smoke can be adsorbed into the interior of the safety monitoring cabinet 2 in the first time, and then sensed by the electrical equipment monitoring smoke alarm 12. After sensing the smoke, the electrical equipment monitoring smoke alarm 12 will quickly sound an alarm to remind the staff of the fire. The electrical equipment monitoring smoke alarm 12 is a photoelectric smoke alarm, which uses the scattering effect of smoke on light to detect smoke. When smoke enters the sensing chamber, smoke particles will scatter part of the light beam to the sensor. As the smoke concentration increases, more light will be scattered to the sensor. When the light of the sensor reaches a certain level, the buzzer will sound. Compared with the natural drifting speed of traditional smoke, it takes a long time for it to drift to the electrical equipment monitoring smoke alarm 12 and be sensed. Failure to issue an alarm in time will cause greater losses. This technical solution uses the cooperation of the induced draft fan 9 and the ventilation hole 6, so that the smoke gas generated at the fire can quickly enter the interior of the security monitoring cabinet 2 and be sensed to issue an alarm, thereby avoiding the rapid spread of fire and burning electrical equipment and causing more losses, thereby minimizing the losses caused by the fire.

[0038] In this technical solution, further, preferably

[0039] A wiring through hole 19 is provided on the right side of the security monitoring cabinet 2, and an anti-offline mechanism 7 is provided outside the wiring through hole 19, and the anti-offline mechanism 7 includes a screw bracelet 13, a screw rod 14, a support block 15, a clamping arc ring 16, a rotating ball 17 and a protective pad 18. The support block 15 is plugged with a screw rod 14, and one end of the screw rod 14 is located on one side of the support block 15 and is provided with a screw bracelet 13, and the other end of the screw rod 14 is located on the other side of the support block 15 and is provided with a clamping arc ring 16, and the clamping A protective pad 18 is provided on the arc inner wall of the arc ring 16, and a rotating ball 17 is provided at the connection between the screw 14 and the clamping arc ring 16. The rotating ball 17 is a spherical structure, and a groove is embedded in the connection between the clamping arc ring 16 and the rotating ball 17. The rotating ball 17 is inserted in the groove and can rotate. The support block 15 is fixedly connected to the outer wall of the security monitoring cabinet 2 by welding. A threaded hole is provided inside the support block 15, and the screw 14 is inserted in the threaded hole to be screwed and moved;

[0040] When the external power cord is inserted into the wiring through hole 19, it will first be inserted into the anti-offline mechanism 7. At this time, the screw bracelets 13 on both sides can be screwed to rotate the screw 14. At this time, the screw 14 begins to rotate and move in the threaded hole inside the support block 15, thereby driving the inner connected clamping arc ring 16 to move inward, and then squeeze the inserted power cord, and use the arc calipers of the two clamping arc rings 16 to clamp the power cord inside to prevent the power cord from falling off due to external force or its own gravity after connection. The connection between the screw 14 and the threaded hole is relatively tight and will not loosen without the action of external rotation, so that the power cord can be well clamped and fixed, and the protective cover provided on the arc inner wall of the clamping arc ring 16 The pad 18 is made of rubber and will undergo elastic deformation after contacting the power cord. On the one hand, it increases the friction between the power cord and makes the connection more secure. On the other hand, it utilizes the softness of the rubber material to protect the power cord and will not cause damage to the power cord due to operations such as squeezing and pulling. In addition, a rotating ball 17 is provided at the connection between the screw 14 and the protective pad 18. The rotating ball 17 is a spherical structure, and a groove is embedded in the connection between the protective pad 18 and the rotating ball 17. The rotating ball 17 can rotate when inserted into the groove. Therefore, when clamping the external power cord, the power cord that is plugged in will not be loose. It only needs to rotate the clamping arc ring 16 to adjust its angle. In this way, power cords that are plugged in in different directions can be clamped and fixed, which is more applicable.

[0041] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
