Description

Technical Field

[0001] The utility model belongs to the field of equipment monitoring, and in particular relates to an automatic alarm calling device for equipment shutdown. Background Art

[0002] During the operation of the equipment, various factors may cause downtime. If the downtime is not discovered in time, it will not only reduce production, but also cause freezing and blockage in winter, causing equipment damage. There are three ways to detect downtime: 1. Through video monitoring; 2. Through the intelligent remote system to monitor the outlet pressure data of the machine-collected well; 3. Through on-site inspections. However, it is impossible to detect the status of some equipment through video monitoring, such as screw pump oil wells, electric pump wells, injection pumps, etc. The status of the machine-collected well can only be judged by the pressure data monitored by the intelligent remote system, but the pressure data needs to be updated every 20 minutes, so the operating status of the equipment cannot be judged in time. In the on-site inspection, it is also necessary to listen and observe at a close distance to judge the status of the equipment, and the inspection time is once every four hours, which will also cause the downtime to be discovered in time. In view of this problem, it is necessary to design a device that is safe and reliable, easy to disassemble and assemble, and can accurately and timely judge the operating status of the equipment from a long distance through mobile phone text messages, video monitoring and on-site inspections.

[0003] Based on this, the utility model proposes an automatic alarm calling device for equipment shutdown. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, that is, when the equipment is shut down, there are blind spots in the video monitoring, slow data update of the remote system and long intervals between on-site inspections, which lead to delayed detection of the shutdown, the utility model provides an automatic alarm calling device for equipment shutdown, including a control power switch, a voltage conversion device, a wireless data collector, an alarm device and an AC contactor;

[0005] The control power switch is electrically connected to the input end of the voltage conversion device, the wireless data collector and the alarm device are connected in parallel between the two output ends of the voltage conversion device, the wireless data collector is electrically connected to the receiving end, and the alarm device is used to send an alarm signal;

[0006] The coil of the AC contactor is connected in parallel with the main AC contactor coil in the starting cabinet, and the normally closed contact of the AC contactor controls the circuit of the automatic alarm calling device when the equipment is shut down.

[0007] In some preferred embodiments, the voltage conversion device includes a transformer.

[0008] In some preferred embodiments, the alarm device includes an alarm light and an alarm sound.

[0009] In some preferred implementations, the alarm light and the alarm sound are connected in parallel, and are connected in parallel with the wireless data collector via an on-off circuit.

[0010] In some preferred implementations, the wireless data collector is used to send a shutdown signal to the receiving end when a shutdown failure occurs in the device.

[0011] In some preferred embodiments, the voltage conversion device is used to convert a 220V voltage into a 12V voltage.

[0015] Other features, objects and advantages of the present application will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

[0016] Figure 1 The utility model is a structural connection diagram of an automatic alarm calling device for equipment shutdown. DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] like Figure 1 As shown, the utility model provides an automatic alarm calling device for equipment shutdown, comprising a control power switch 1, a voltage conversion device 2, a wireless data collector 3, an alarm device and an AC contactor 6;

[0020] The control power switch 1 is electrically connected to the input end of the voltage conversion device 2, the wireless data collector 3 and the alarm device are connected in parallel between the two output ends of the voltage conversion device 2, the wireless data collector 3 is electrically connected to the receiving end, and the alarm device is used to send an alarm signal;

[0021] The coil of the AC contactor 6 is connected in parallel with the main AC contactor coil in the starter cabinet, and the normally closed contact of the AC contactor 6 controls the circuit of the automatic alarm calling device for the equipment shutdown.

[0022] The alarm device includes an alarm light 4 and an alarm sound 5 .

[0023] Wherein, the control power switch 1 is connected to the starting cabinet.

[0024] When the utility model is in use, after the control power switch 1 is turned on, it starts to work, and the voltage conversion device 2 converts the 220V voltage into a 12V safe voltage. The coil of the AC contactor 6 is connected in parallel with the coil of the main AC contactor of the starter cabinet. When the starter cabinet is running, the AC contactor 6 and the main AC contactor in the starter cabinet are synchronously attracted. The normally closed contact of the AC contactor 6 is disconnected, and the alarm device does not work. When a shutdown failure of the equipment occurs, the main AC contactor of the starter cabinet is powered off, and the AC contactor 6 is powered off at the same time, and the normally closed contact of the AC contactor 6 is connected. The alarm light 4 on the on-site starter cabinet flashes, and the alarm sounder 5 sounds an alarm. At the same time, the wireless data collector 3 collects the switch signal and sends a shutdown text message to the mobile phone of the on-duty personnel.

[0025] Specifically, the voltage of the warning light 4 is 12V, and the voltage of the warning sound 5 is also 12V.

[0026] The automatic alarm and call device for equipment shutdown of the utility model is suitable for electrical equipment in remote locations, which are difficult to observe and have the risk of equipment damage if shut down for a long time. Most electrical appliances achieve safe voltage to avoid safety risks, and are easy to install and disassemble. The automatic alarm and call device for equipment shutdown uses the suction state of the main AC contactor 6 in the monitoring starter cabinet to provide a signal for the automatic alarm and call device for equipment shutdown, and uses a 12V safe voltage after operation.

[0027] As a further explanation of the present invention, the voltage conversion device 2 includes a transformer.

[0028] The voltage conversion device 2, that is, the transformer, is used to convert the 220V voltage into a 12V voltage.

[0030] For further explanation of the present invention, see Figure 1 The wireless data collector 3 is used to send a shutdown signal to the receiving end when a shutdown failure occurs in the device.

[0031] As a further explanation of the present invention, the alarm device is installed on the starting cabinet.
