Technical Field
[0001] The utility model relates to the technical field of slip ring boxes, in particular to an automatic control mechanism for detecting temperature and humidity of a port electrical slip ring box. Background Art
[0002] Slip ring box is a device used to transmit electrical energy and signals. It is usually installed at the rotation center of the equipment. It consists of two major parts, rotating and stationary. It is mainly used to connect rotating bodies and transmit energy and signals. In ports, slip ring boxes are also used in ships, coastal defense, offshore wind turbines, underwater robots, ship propulsion systems, propeller systems, winches, shipborne radars, port machinery and other related maritime equipment. At present, in port equipment, most of the commonly used cable slip ring boxes are used to power important loading and unloading equipment such as ship unloaders, ore and coal loaders, bucket wheel excavators, ship loaders, etc., so the normal operation and service life of electrical slip ring boxes are crucial.
[0003] At present, the electrical slip ring box in the bulk port machinery equipment is the power supply device of the whole equipment, most of which are powered by 10kV high voltage, and most of the electrical slip ring boxes are composed of carbon brushes, slip rings, high-voltage cables, insulating terminals, etc. In normal use, condensation and excessive temperature in the box are often caused by poor sealing in the box or large temperature difference between the inside and outside of the box. This will cause excessive humidity and temperature in the box, thereby causing power failures such as power outages to affect equipment operation. At the same time, excessive humidity in the box will also affect the insulation performance of the components in the electrical slip ring box, and even cause serious faults such as short-circuit discharge and explosion. However, the current electrical slip ring box cannot perform complete automatic control of heating and dehumidification. Therefore, there is an urgent need for an automatic control mechanism for temperature and humidity detection of port electrical slip ring boxes to solve the above-mentioned technical problems. Utility Model Content
[0004] The content of this utility model is used to introduce the concepts in a brief form, which will be described in detail in the following specific implementation. The content of this utility model is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In view of the problems and shortcomings in the prior art, the utility model provides a temperature and humidity detection control device for a port electrical slip ring box, which connects the temperature and humidity detection sensor and the dehumidification heater inside the electrical slip ring box through a temperature and humidity detection controller to monitor the temperature and humidity inside the slip ring box in real time. The dehumidification heater is monitored in real time as required, and the dehumidification heating relay and the power supply relay are combined to realize automatic control of the temperature and humidity inside the electrical slip ring box, ensuring that the temperature and humidity inside the electrical slip ring box meet the requirements for safe operation. It is used to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a temperature and humidity detection sensor and a dehumidification heater arranged inside an electrical slip ring box, and a temperature and humidity detection controller and a current sensor arranged outside the electrical slip ring box; the input and output interfaces of the temperature and humidity detection controller, the dehumidification heater and the current sensor are respectively connected to the live wire and the neutral wire ends of the wiring terminals, the control input interface of the temperature and humidity detection controller is connected to the output interface of the temperature and humidity detection sensor, and the control output interface of the temperature and humidity detection controller is connected to the control input interface of the dehumidification heater; a dehumidification heating relay is connected between the output interface of the dehumidification heater and the wiring terminals, and a power supply relay is connected between the output interface of the current sensor and the wiring terminals.
[0007] Preferably, a dehumidification heating alarm is provided between the output interface of the dehumidification heater and the wiring terminal. The dehumidification heating alarm is used to realize the abnormal alarm function, set the temperature and humidity warning values according to actual needs, and set the start conditions of the sound and light alarm at the same time. When the temperature and humidity detection sensor senses that the temperature and humidity in the box are not within the set range, the control port of the temperature and humidity detection controller is triggered to control the dehumidification heater to work, and the dehumidification heating alarm prompts an alarm to remind the operator.
[0008] Preferably, a power alarm is provided between the output interface of the current sensor and the wiring terminal. The power alarm is also used to realize the abnormal alarm function. When the current sensor senses that there is no current passing through the line, it indicates that the electrical slip ring box has a power failure, and the power alarm is triggered to promptly alarm and remind the operator to handle it.
[0009] Preferably, the temperature and humidity detection controller, current sensor, dehumidification heating alarm and power supply alarm are remotely connected to the port electrical automation PLC system. In the utility model, the temperature and humidity detection controller, current sensor, dehumidification heating alarm and power supply alarm are remotely connected to the port electrical automation PLC system for realizing the remote alarm function. When the temperature and humidity detection sensor in the electrical slip ring box senses that the temperature or humidity in the box exceeds the set allowable range value, the dehumidification heater starts working and the heater alarm lights up, and at the same time sends a fault signal to the remote PLC system to promptly notify the operator to troubleshoot and handle the fault.
[0010] Preferably, the dehumidification heating relay and the power supply relay adopt an intermediate relay. The intermediate relay is a special switching device. When the relay coil is energized, the magnetic field generated will attract the iron core to close or open the contacts, thereby realizing the control of the circuit. In addition, since the intermediate relay usually has more contacts, it can better meet the complex circuit control requirements.
[0011] Preferably, the model of the temperature and humidity detection controller is Ankerui WHD20R.

[0015] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.
[0016] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.
[0017] Example
[0018] Reference Figure 1 As shown, this embodiment provides an automatic control mechanism for temperature and humidity detection of a port electrical slip ring box, including a temperature and humidity detection sensor and a dehumidification heater arranged inside the electrical slip ring box, and a temperature and humidity detection controller and a current sensor arranged outside the electrical slip ring box; the input and output interfaces of the temperature and humidity detection controller, the dehumidification heater and the current sensor are respectively connected to the live wire and the neutral wire ends of the wiring terminals, the control input interface of the temperature and humidity detection controller is connected to the output interface of the temperature and humidity detection sensor, and the control output interface of the temperature and humidity detection controller is connected to the control input interface of the dehumidification heater; a dehumidification heating relay is connected between the output interface of the dehumidification heater and the wiring terminals, and a power relay is connected between the output interface of the current sensor and the wiring terminals.
[0019] The utility model can disconnect the dehumidification heating relay and the power supply relay to stop the operation of the electrical slip ring box when the temperature inside the electrical slip ring box is higher than the maximum temperature or when the humidity inside the electrical slip ring box is lower than the maximum temperature, and can also well realize the isolation of electrical signals to protect the electrical components in the circuit from interference. And by using the current sensor, the working state of the electrical slip ring box can also be timely discovered, that is, when the current sensor detects that there is no current passing through the circuit, it indicates that the electrical slip ring box has a power failure and needs to be handled by the operator. Similarly, when the current sensor detects that the current in the circuit is too high, the power supply relay can be disconnected in time to stop the circuit from working, thereby realizing the protection of the electrical slip ring box. The temperature and humidity detection sensor determines that the humidity or temperature inside the electrical slip ring box is too high or too low, and the temperature and humidity detection controller controls the selection of the working state of the dehumidification heater to achieve the adjustment of the temperature or humidity inside the electrical slip ring box.
[0020] This embodiment also includes that a dehumidification heating alarm is added between the output interface of the dehumidification heater and the wiring terminal, and a power supply alarm is added between the output interface of the current sensor and the wiring terminal. The dehumidification heating alarm and the current alarm are both used to realize the abnormal alarm function. When the current sensor senses that there is no current passing through the line, it indicates that there is a power failure in the electrical slip ring box, and the power supply alarm is triggered to alarm in time to remind the operator to deal with it. When the temperature and humidity detection sensor senses that the temperature and humidity in the box are not within the set range, the control port of the temperature and humidity detection controller is triggered to control the dehumidification heater to work, and at the same time the dehumidification heating alarm prompts an alarm to remind the operator.
[0021] This embodiment also includes that the temperature and humidity detection controller, the current sensor, the dehumidification and heating alarm and the power alarm are remotely connected to the port electrical automation PLC system. When the temperature and humidity detection sensor measures that the temperature or humidity in the electrical slip ring box exceeds the set allowable range value, the dehumidification heater starts working and the dehumidification and heating alarm lights up, and at the same time sends a fault signal to the remote electrical automation PLC system, notifying the operator in time to troubleshoot and handle the fault.
[0022] This embodiment also includes that the dehumidification heating relay and the power supply relay use intermediate relays, and the model of the temperature and humidity detection controller uses Ankerui WHD20R. The temperature and humidity detection control box is equipped with an Ankerui brand temperature and humidity detection controller with model WHD20R. Ankerui WHD series temperature and humidity detection controller uses temperature and humidity detection sensors to detect temperature and humidity values, and adjusts the temperature and humidity values by controlling external fans and heaters, which can effectively prevent equipment failures caused by low temperature and high temperature, as well as creepage and flashover accidents caused by moisture or condensation. Since intermediate relays usually have more contacts, they can better meet complex circuit control requirements.
[0023] Method of using the utility model
[0024] During operation, the minimum and maximum temperatures allowed in the electrical slip ring box are set in real time according to the seasonal conditions. When the temperature in the box measured by the temperature and humidity detection sensor is lower than the minimum temperature, the control output port of the temperature and humidity detection controller is triggered to energize and close the dehumidification heating relay, and directly control the dehumidification heater to start working. After the dehumidification heater has been working for a period of time, if the temperature and humidity detection sensor measures that the temperature in the box is higher than the maximum temperature, the control output port of the temperature and humidity detection controller is closed to deenergize the dehumidification heating relay, and the dehumidification heater can be directly shut down and stop working.
[0025] At the same time, the minimum and maximum humidity allowed in the electrical slip ring box are set in real time according to the seasonal conditions. When the humidity in the box measured by the temperature and humidity detection sensor is lower than the set minimum humidity, the control output port of the temperature and humidity detection controller is closed to disconnect the dehumidification heating relay, and the dehumidification heater is turned off to stop working. When the humidity in the box measured by the temperature and humidity detection sensor is higher than the set maximum humidity, the control output port of the temperature and humidity detection controller is triggered to energize and close the dehumidification heating relay, and control the dehumidification heater to start working.
[0026] In addition, when the dehumidification heating relay is energized, it means that the temperature or humidity inside the electrical slip ring box needs to be adjusted. The connected dehumidification heating alarm lights up to alarm, and at the same time sends fault information to the PLC system far away at the port. When the current sensor detects that the current in the line is too high, the power relay is disconnected in time to stop the line from working, and the connected power alarm lights up to alarm, and at the same time, the fault information needs to be sent to the PLC system far away at the port.
