Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation fans, and in particular relates to a humidity monitoring and self-adaptive regulating system for a pump room. Background Art

[0002] In modern high-rise buildings, secondary water supply pump rooms are important facilities to ensure the living water supply of residents. The operating environment has a direct impact on the performance and life of the equipment. Humidity is one of the key factors affecting the pump room environment. Excessive humidity will not only accelerate the corrosion and aging of equipment, but may also cause failures of electrical equipment, increase maintenance costs and downtime. Therefore, effective humidity monitoring and regulation are essential for the management of secondary water supply pump rooms in high-rise buildings.

[0003] The existing ventilation fan installation structure and ventilation fan device (publication number: CN214533733U) generally have the following problems during use:

[0004] 1. Failure to start in time when the humidity in the pump room exceeds the threshold: Equipment failure: High humidity environment easily causes electrical equipment to get damp, which in turn causes short circuits, leakage and other faults, affecting the normal operation of the equipment. Corrosion problem: Excessive humidity will accelerate the corrosion of metal parts, shorten the service life of the equipment, and increase maintenance and replacement costs. Therefore, a pump room humidity monitoring and adaptive adjustment system that automatically starts when the humidity exceeds the threshold is urgently needed.

[0005] 2. Failure to add protection structures as needed: Overload damage: If the circuit protection device fails or the power supply is not disconnected in time, the ventilation fan may continue to run under overload conditions, causing the motor and other electronic components to overheat and eventually damage. Circuit failure: A single circuit protection structure cannot provide redundant protection. Once the protection device fails, the entire system may be exposed to the risk of electrical failure, increasing the equipment failure rate. Therefore, a pump room humidity monitoring and adaptive adjustment system with a circuit protection structure is urgently needed.

[0006] 3. It is inconvenient to repair and replace the motor when it is damaged: Extended downtime: It takes more time to repair and replace the motor, which may cause the pump room ventilation system to shut down for a long time and fail to effectively control the humidity. Exacerbated equipment damage: If the motor is damaged but cannot be repaired in time, other related components or systems may be further damaged due to continued moisture, so a pump room humidity monitoring and adaptive adjustment system that is convenient for repairing and replacing motors is urgently needed.

[0039] Humidity sensor: Installed on the top of the control box, using TE Connectivity's HTU21D model, used to monitor the humidity changes in the secondary water supply pump room in real time and transmit data to the central control module.

[0040] Control box door: It is set at the front of the control box, and the control box locking module is installed in the middle of the right side to ensure the safety and airtightness of the control box. The control box locking module adopts the CL-501 model of Essentra Components.

[0041] Switch shaft: It is set on the left side of the back of the control box, using ABB's OHB65J6 model, which is convenient for turning the power on and off and controlling the power supply of the system.

[0042] External power cord: installed on the left side of the power control box, it provides a stable power supply for the entire system and ensures the normal operation of the system.

[0043] Central control module: It is located in the middle of the control box and adopts the 1766-L32BXB model of Rockwell Automation. It is responsible for receiving the data of the humidity sensor and automatically controlling the start and stop of the rotating motor according to the set threshold value.

[0044] Air switch: It is set on the left side of the central control module and adopts Siemens' 3RV2021-1DA10 model. It can automatically cut off the power when the circuit is overloaded to protect the electrical components and prevent the equipment from being damaged due to overcurrent.

[0045] Wires: Wires connect the central control module with the rotating motor, humidity sensor and air switch to achieve the transmission of electrical signals and ensure the coordinated work of each component.

[0046] Operation logic of each component in the control box:

[0047] Humidity sensor: The humidity sensor monitors the humidity in the pump room in real time and transmits the humidity data to the central control module. The humidity sensor is installed on the top of the control box to accurately measure the air humidity in the pump room.

[0048] Central control module: After receiving the data from the humidity sensor, the central control module determines whether the current humidity exceeds the preset threshold. If the humidity exceeds the threshold, the central control module starts the rotating motor through the wires to drive the ventilation fan blades to operate and discharge moisture. When the humidity returns to the normal range, the central control module will automatically stop the operation of the rotating motor to save energy.

[0049] Air switch: The air switch is installed on the left side of the central control module to monitor the current of the circuit. When the current exceeds the preset safety value, the air switch will automatically disconnect the circuit and cut off the power supply to protect the electrical components from damage. This protection mechanism of the air switch can prevent the electrical components from burning due to overload and reduce the risk of fire.

[0050] Switch shaft: The switch shaft is installed on the left side of the back of the power control box. By rotating the switch shaft, the user can manually control the power on and off of the power control box, which is convenient for maintenance and repair operations.

[0051] Control box locking module: The control box locking module is installed in the middle of the right side of the control box door, and is used to lock and unlock the control box door to ensure that the equipment inside the control box is safe from external interference. The locking module is designed to be easy to operate and can be opened quickly when inspection or maintenance is required.

[0052] External power cord: The external power cord connects the power control box with the external power supply to provide power supply for the system. The power cord passes through the left side of the power control box to ensure the stability and safety of the power supply.

[0053] Wires: Wires are used to connect the central control module with the humidity sensor, rotating motor and air switch to ensure the transmission of signals and power. The wires are arranged inside the control box to avoid interference and damage from the external environment.

[0054] The coordination logic of each component at runtime:

[0055] Humidity monitoring and adaptive adjustment: The humidity sensor monitors the humidity in the pump room and transmits the data to the central control module. When the humidity exceeds the set threshold, the central control module starts the rotating motor to drive the ventilation fan blades to exhaust moisture and reduce the humidity in the pump room. When the humidity returns to normal, the central control module automatically stops the rotating motor.

[0056] Overload protection: The air switch monitors the circuit current in real time. When the current exceeds the safe value, it automatically cuts off the power to protect the equipment. After the power is cut off, maintenance personnel can turn off the system power supply through the switch shaft to check and solve the overload problem.

[0057] Motor maintenance and replacement: The rotating motor is fixed by connecting and fixing modules and structural fixing bolts. When the motor fails, maintenance personnel only need to remove the structural fixing bolts to disassemble the rotating motor and connecting and fixing modules for repair and replacement. After the repair is completed, tighten the bolts again to resume normal operation.

[0058] As high-rise residential buildings in cities are continuously put into use, the management scale of secondary water supply pump rooms is large. The traditional inspection management method is labor-intensive and has exposed many problems during operation, which cannot meet the current needs of water supply safety. Therefore, it is necessary to reduce the workload of secondary water supply inspectors through intelligent management methods.

[0059] Take Jinan as an example: According to statistics, the maintenance and inspection workload of the secondary water supply pump room in the urban area in 2021 was close to 1,500 times, with a cost of about 900,000 yuan; due to equipment failure, external line power outage, front-end voltage reduction, pipeline leakage and other problems, the water outage and voltage reduction emergency repair workload was close to 100 times, and the maintenance work also reached about 300 times, with a cost of about 460,000 yuan. After analysis and refined inspections, some sudden equipment failures can be avoided in advance by improving the internal environmental humidity of the pump room. Some can also be predicted through analysis of humidity data changes, and potential hidden dangers can be dealt with in advance to achieve the purpose of extending the maintenance cycle and reducing the frequency of maintenance.

[0060] Jinan Water Group completed the construction of the secondary water supply pump room monitoring and management platform in 2016. The existing system was independently developed by the group's subsidiary Puli Electric Control Company. The group has complete intellectual property rights and core technologies, which has laid a good working foundation for subsequent intelligent upgrades and renovations. The existing monitoring and management system has completed the detection of operating status signals of major equipment, including all unit equipment, valve equipment, fan equipment, sewage pump equipment, etc. in the pump room; the system collects all operating instrument data, including pressure signals, flow signals, and some power distribution data signals. The automatic control system also has unattended remote control functions. The entire system is relatively complete, providing strong data support for smart inspections. The pump room humidity monitoring and adaptive adjustment system provided in this application is an effective supplement to the functions of the existing automatic control system.

[0061] Through the above structure and working principle, the utility model realizes intelligent monitoring and adaptive adjustment of the humidity in the pump room, ensures the safety of the equipment and the environment, and at the same time improves the maintenance efficiency and reliability of the system through reasonable design.
