Description

Technical Field

[0001] The utility model relates to the technical field of electrical control, in particular to an intelligent measuring switch with undervoltage protection and alarm functions. Background Art

[0002] Measuring switch (circuit breaker) refers to a switch device that can close, carry and break the current under normal circuit conditions and close, carry and break the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. At present, intelligent measuring switches have added communication, calculation, voltage protection and alarm functions on the original basis.

[0003] However, most of the current alarm functions only add warning lights and buzzers to the measuring switch body. The warning lights and buzzers are powered by a backup power supply installed inside the measuring switch. The backup power supply will be insufficient after a period of use. After the measuring switch is undervoltage protected, it will be powered off to protect the connected electrical equipment. Therefore, the power of the backup power supply will not be replenished. After the backup power supply is exhausted, the warning lights and buzzers will stop working. If the staff fails to find the problem with the measuring switch in time during the working period of the warning lights and buzzers, the problem of untimely maintenance will also occur.

[0004] At present, an existing intelligent measuring switch (such as patent number: CN218241745U) discloses an intelligent measuring switch, including a lower shell, an upper shell and a protective cover connected in sequence, the lower shell is rotatably connected to a handle, and also includes a crossbar, a rack, a transmission rod, a motor and a control panel, the upper shell is provided with a slide and a slide rail, the slide is slidably connected to the crossbar, the handle is clamped to the crossbar, the crossbar is fixedly connected to the rack, the upper shell is rotatably connected to the transmission rod, the rack is meshed with the transmission rod, the transmission rod is connected to the motor, and the upper shell is fixedly connected to a control panel for controlling the operation of the motor. The purpose of the utility model is to control the movement of the crossbar by a motor so that the crossbar pushes the handle to close / open the gate, and the crossbar is clamped in the handle so that the handle is exposed, which satisfies the needs of manual control while meeting the requirements of intelligent control, and has a simple structure and convenient operation.

[0005] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the existing device is not equipped with an alarm device. When the device body automatically trips due to undervoltage protection, it is unable to promptly remind the staff to perform maintenance. This may cause the staff to miss the best time for maintenance because they cannot quickly find the problem or even do not know that there is a problem with the device. If the device is used in a production department, the machinery and equipment connected to the device will stop working due to power outages, which may cause large economic losses.

[0016] (III) Beneficial effects

[0017] 1. The present application is provided with a warning light and a buzzer. When the device as a whole triggers the undervoltage protection, the measuring switch body will be disconnected and the power will be cut off. At this time, the battery installed inside the measuring switch body will supply power to the control mechanism. The control mechanism supplies power to the warning light and the buzzer and starts the warning light to emit a warning light. At the same time, the buzzer emits a buzzing sound. The warning light and the buzzer cooperate to warn the staff that the device is damaged and remind the staff to repair it. This solves the problem that the existing device is not provided with an alarm function. If damage occurs during the operation of the device, it is not easy to remind the staff to repair it in time.

[0018] 2. The present application is provided with a warning mechanism. When the battery power inside the measuring switch body is about to be exhausted, if the staff still does not find the problem, the control mechanism will supply power to the warning light and start the electric telescopic rod to extend. The electric telescopic rod pushes the slider to slide out of the slide slot, revealing the warning plate and the flashing part. When the battery in the measuring switch body is completely exhausted, the warning light and the buzzer will be turned off due to lack of power supply. At this time, the warning plate and the flashing part are used to warn the staff. Moreover, because the hanging rope is soft, the reflective block can be slightly deflected and shaken with the airflow based on the hanging rope, so that the reflective function of the reflective block can reflect at a wider angle. At the same time, when the staff observes the flashing part from a distance, they will find that the reflective block flashes because it is shaking, so that the staff can more easily notice the device as a whole. Therefore, when the warning light and the buzzer cannot work, the present application still has a backup alarm function, and this alarm function does not require energy and can serve as a warning for a long time.

The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides an intelligent measuring switch with undervoltage protection and alarm functions, comprising a shell 1, a control mechanism 2 and a measuring switch body 3 are fixedly installed on the shell 1, the control mechanism 2 comprises a display screen, an operation button and a control lever, the measuring switch body 3 comprises a battery, the control mechanism 2 is arranged on the top surface of the shell 1, the measuring switch body 3 is arranged inside the shell 1, the control mechanism 2 is electrically connected to the measuring switch body 3, an alarm mechanism is also fixedly installed on the top surface of the shell 1, a fixing plate 5 is fixedly installed on the side wall of the shell 1, the fixing plate 5 is provided with a slide groove 501, and the fixing plate 5 is also provided with four limit grooves 502, a warning mechanism 6 is arranged inside the shell 1, the warning mechanism 6 is slidably connected to the fixing plate 5, a flashing member 7 is fixedly connected inside the warning mechanism 6, the warning mechanism comprises a warning light 401 and a buzzer 402, the warning mechanism 6 comprises an electric telescopic rod 601, the electric telescopic rod 601 is electrically connected to the control mechanism 2, and the flashing member 7 comprises a hanging rope 701.

[0029] The warning light 401 and the buzzer 402 are both fixedly connected to the top surface of the housing 1 , and the warning light 401 and the buzzer 402 are both electrically connected to the control mechanism 2 .

[0030] The electric telescopic rod 601 is fixedly connected to the inner wall of the shell 1, and the output end of the electric telescopic rod 601 is fixedly connected to a slider 602, the slider 602 is in a mouth shape, and the slider 602 is fixedly connected to four limit blocks 603, the slider 602 is slidably connected in the slide groove 501, and the four limit blocks 603 are respectively slidably connected in the four limit grooves 502.

[0031] The upper and lower surfaces of one end of the slider 602 away from the electric telescopic rod 601 are fixedly connected with sealing strips 604 , and the sealing strips 604 cooperate with the fixing plate 5 .

[0032] A warning plate 605 is fixedly connected to the inner wall of the sliding block 602 , and the surface of the warning plate 605 is sprayed with red paint.

[0033] The hanging rope 701 is fixedly connected to the slider 602 , and a plurality of reflective blocks 702 are fixedly arranged in the middle section of the hanging rope 701 .

[0034] The present application is provided with a warning mechanism 6. When the battery power inside the measuring switch body 3 is about to run out, if the staff still does not find the problem, the control mechanism 2 will supply power to the warning light 401 and start the electric telescopic rod 601 to extend. The electric telescopic rod 601 pushes the slider 602 to slide out of the slide groove 501, revealing the warning plate 605 and the flashing element 7.

[0035] Working principle:

[0036] In the first step, the device needs to be installed vertically, with the side where the control mechanism 2, the warning light 401 and the buzzer 402 are set as the front, and the side away from the control mechanism 2 is against the wall. When the device as a whole triggers the undervoltage protection, the measuring switch body 3 will be disconnected and the power will be cut off. At this time, the battery installed inside the measuring switch body 3 will supply power to the control mechanism 2, and the control mechanism 2 will supply power to the warning light 401 and the buzzer 402 and start the warning light 401 to emit a warning light. At the same time, the buzzer 402 will emit a buzzing sound. The warning light 401 and the buzzer 402 cooperate to warn the staff that the device is damaged and remind the staff to repair it.

[0037] In the second step, when the battery power inside the measuring switch body 3 is about to run out, if the staff still does not find the problem, the control mechanism 2 will supply power to the warning light 401 and start the electric telescopic rod 601 to extend, and the electric telescopic rod 601 will push the slider 602 to slide out of the slide groove 501, revealing the warning plate 605 and the flashing element 7. When the battery inside the measuring switch body 3 is completely exhausted, the warning light 401 and the buzzer 402 will be turned off due to lack of power supply. At this time, the warning plate 605 and the flashing element 7 are used to warn the staff, and because the hanging rope 701 is soft, the reflective block 702 can be slightly deflected and shaken based on the hanging rope 701 with the airflow, so that the reflective function of the reflective block 702 can reflect at a wider angle. At the same time, when the staff observes the flashing element 7 from a distance, they will find that the reflective block 702 is flashing because it is shaking, making it easier for the staff to notice the device as a whole.
