Description

Technical Field

[0001] The utility model relates to the technical field of ventilation systems, and more specifically, to an intelligent ventilation system for a subway transfer station based on passenger flow. Background Art

[0002] Subway transfer stations are the most important nodes in the urban rail transit network, allowing passengers to transfer between different lines.

[0003] The intelligent ventilation system for subway transfer stations is a comprehensive system designed to automatically adjust ventilation volume based on real-time conditions such as passenger flow and environmental parameters in subway transfer stations to maintain air quality and comfort in the station.

[0004] The traditional intelligent ventilation and air exchange system for subway transfer stations based on the size of passenger flow has the following shortcomings: the traditional intelligent ventilation and air exchange system for subway transfer stations based on the size of passenger flow usually has multiple ventilation and air exchange devices, which are installed in places with large passenger flow such as on both sides of the platform. When the passenger flow becomes smaller, energy saving can be achieved by shutting down some ventilation and air exchange devices or reducing the ventilation and air exchange volume. Most ventilation devices will have dust nets at the air outlet. Due to the large passenger flow in subway stations, dust and dirt are easily accumulated on the dust nets, so they need to be cleaned regularly. However, due to the complexity of the cleaning work and space limitations, the cleaning cycle may be relatively long, which may have a certain impact on the normal operation of the station. Therefore, it needs to be improved. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an intelligent ventilation system for a subway transfer station based on passenger flow, which has the advantage of being conducive to ventilation.

[0008] As an optimal technical solution of the present invention, a transmission plate is movably installed inside the rectangular groove, the transmission plate is located above the inclined block, and a return spring is elastically installed between the inner side of the transmission plate and the inner side of the rectangular groove.

[0009] As an optimal technical solution of the present invention, vertical grooves are opened on both sides of the rectangular groove, and a limiting rod is fixedly installed inside the vertical groove. Both ends of the transmission plate extend into the interior of the vertical groove and are movably connected to the outside of the limiting rod.

[0010] As a preferred technical solution of the present invention, limiting grooves are provided on both sides of the movable groove, and limiting blocks located inside the limiting grooves are fixedly installed on both sides of the bottom of the inclined block.

[0011] As a preferred technical solution of the present invention, a fan is fixedly installed above the shell, an air duct is fixedly installed at the front end of the fan, and the other end of the air duct extends to the inside of the empty slot.

[0012] As a preferred technical solution of the present invention, a second reset spring is elastically installed at the bottom of the slot, and the second reset spring is located above the clamping block.

[0013] As an optimal technical solution of the present invention, a pull ring is movably installed below the dustproof net, a rotating shaft extending to the top of the dustproof net is fixedly installed above the pull ring, and a fixed block is fixedly installed above the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The utility model pushes the dustproof net upward, and the transmission plate is squeezed and retracted into the inside of the movable groove by the extrusion force, so that the inclined surface block squeezes the transmission plate and moves upward with the dustproof net, and then pulls the dustproof net downward, so that the transmission plate moves downward with the inclined surface block, and the dustproof net moves downward and separates from the inside of the installation groove. Compared with the traditional intelligent ventilation and air exchange system of subway transfer stations based on the size of passenger flow, this intelligent ventilation and air exchange system of subway transfer stations based on the size of passenger flow only needs to push the dustproof net upward to make the inclined surface block and the transmission plate fit together, and then pull the dustproof net downward to remove it, which is easy to use.

[0016] 2. The utility model presses the temperature sensor upward to disengage the card block from the inside of the card slot, and rotates the card block to the bottom of the slot. The reset spring releases the elastic potential energy to push the card block out of the inside of the slot, thereby removing the temperature sensor. Compared with the traditional intelligent ventilation and air exchange system of subway transfer stations based on the size of passenger flow, this intelligent ventilation and air exchange system of subway transfer stations based on the size of passenger flow presses and rotates the temperature sensor to move the card block to the top of the slot and remove it, which is easy to use.

[0017] 3. This intelligent ventilation system is equipped with a control system, fans, and temperature sensors. Taking firefighting needs into consideration, if a fire breaks out, the intelligent ventilation system can serve as an emergency response. When the temperature sensor detects a temperature rise, the control system receives a corresponding signal and turns on all fans to exhaust air, while also increasing the fan output. This can quickly exhaust smoke from the station to the outside, while also helping to cool the station. BRIEF DESCRIPTION OF THE DRAWINGS
