Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to ventilation equipment for a transformer room of a municipal drainage pump station. Background Art

[0002] The substation of a municipal drainage pump station refers to an independent building or room used to supply power to a municipal drainage pump station. In the municipal drainage system, the drainage pump station is a facility used to lift and transport wastewater or rainwater, while the substation is a facility required to provide power to the pump station. The substation generally includes electrical equipment such as transformers, switchgear, cables, and distribution devices, which are used to convert the electrical energy of the high-voltage power grid into low-voltage electrical energy and ensure the reliability and stability of power supply. In order to achieve heat dissipation, maintain indoor air circulation, and remove the heat generated by electrical equipment, ventilation equipment is required.

[0003] Because the municipal drainage pump station needs to be kept running all the time to ensure the normal operation of the drainage system. This means that the substation needs to be powered continuously and needs to be monitored and controlled in real time. Therefore, the substation often needs to work uninterruptedly around the clock to deal with any possible failures or emergencies, so as to ensure that the vents are always open. However, when it rains, rainwater can easily enter the interior of the ventilation equipment, causing the equipment components to be damaged by moisture, thus affecting the service life of the device.

[0010] Preferably, the dehumidification assembly further comprises a supporting plate fixedly connected to the interior of the drying chamber, and there are several supporting plates, which are arranged in parallel and staggered manner.

[0011] Preferably, the dehumidification assembly further comprises a ventilation hole opened on the outer side wall of the vertical partition, and the ventilation hole is located above the uppermost supporting plate.

[0012] Preferably, a positioning hole is formed on the outer side wall of the positioning block, a locking hole is formed on the inner side wall of the positioning hole, and the inner diameter of the positioning hole is equal to the outer diameter of the positioning sleeve.

At this time, the ventilation fan will drive the air to pass through the drying chamber first, and then be discharged from the other end of the installation tube. When the air enters the interior of the drying chamber, the moisture in the air will be adsorbed by the desiccant to prevent moisture from damaging the equipment.

[0017] 2. By setting up a sealing door, the drying chamber is sealed to reduce the occurrence of moisture in the desiccant and increase the service life of the device. After the desiccant has been used for a period of time, the electromagnet is energized to make it magnetic, thereby adsorbing the locking rod so that the locking rod is completely retracted into the spring groove. After that, the knob can be rotated to disengage the locking rod from the locking hole, and then the sealing door can be opened to facilitate the replacement of the desiccant.
