Description

Technical Field

[0001] This utility model belongs to the field of fire gate technology, specifically relating to a fire gate that can be opened and closed quickly. Background Technology

[0002] Fire gates play a crucial role in fire protection systems. They are mainly used to control the spread of fire by cutting off or regulating the flow of media in emergencies such as fires, providing valuable time for personnel evacuation and fire rescue.

[0003] Existing fire gates typically employ hydraulic damping technology in their door closers to slow the closing speed, reduce noise, and minimize door wear. However, this hydraulic damping also increases the resistance when opening and closing the door, making it more difficult. This is mainly because the hydraulic damper needs to overcome a certain amount of resistance to achieve the damping effect, thus increasing the difficulty of opening and closing the door.

[0004] Therefore, in response to the problem that the existing fire gates have high damping and require a lot of effort to open and close due to the hydraulic buffering effect inside their door closers, a fire gate that can be opened and closed quickly can be designed. Utility Model Content

[0005] In order to overcome the problem that existing fire gates have high damping and require a lot of effort to open and close due to the hydraulic buffer effect inside the gate closer.

[0006] The technical solution of this utility model is as follows: a fire gate that can be opened and closed quickly, including a fire door, a door closer assembly, and a first temperature sensor; the door closer assembly is provided on the front end face of the fire door panel; the first temperature sensor is provided on the rear end face of the fire door frame; the door closer assembly includes a door closer, a door closing transmission linkage, an oil tank, a pusher, a hydraulic piston pusher, a second temperature sensor, and an oil delivery channel.

[0007] Preferably, the ambient temperature is monitored in real time by a first temperature sensor and a second temperature sensor. Once the temperature rises abnormally, the hydraulic piston propeller is immediately controlled to push the propeller to push the hydraulic oil in the oil tank into the oil chamber inside the door closer along the oil delivery channel, thereby restoring the hydraulic function of the door closer. In the event of a fire, the door closer is restored to a door closer with damping and buffering functions. In a safe environment where no fire occurs, the high damping and buffering characteristics of the door closer are removed, thereby reducing the difficulty of opening and closing the fire door. This solves the problem of existing fire gates, where the hydraulic buffering effect inside the door closer causes high damping and difficulty in opening and closing the fire gate.

[0008] Preferably, the fire door has a door closer on the front face of the door panel, and the outer shell of the door closer is bolted to the front face of the fire door panel; an oil tank is provided at the lower end of the door closer, and the oil tank and the door closer are integrally formed.

[0009] Preferably, the oil storage tank is equipped with a pusher, and the space between the pusher and the oil storage tank is filled with high-temperature resistant hydraulic oil.

[0010] Preferably, an oil delivery channel is provided between the oil storage tank and the door closer, and the oil delivery channel is connected to the hydraulic oil cavity inside the oil storage tank and the door closer.

[0011] Preferably, a hydraulic piston propulsion machine is provided inside the pusher, and the output end of the hydraulic piston propulsion machine pushes the pusher to move along the inside of the oil tank.

[0012] Preferably, the upper end of the door closer is provided with a door closing transmission link, and the two ends of the door closing transmission link are respectively bolted to the front end of the fire door frame and driven by the upper end of the gear shaft inside the door closer.

[0013] Preferably, a second temperature sensor is provided on the front end of the oil storage tank, and the second temperature sensor is wirelessly connected to the electronic control unit of the hydraulic piston propulsion machine, along with the first temperature sensor.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing fire gates suffer from high damping and difficulty in opening and closing due to the hydraulic buffering effect inside the door closer. By using a first and second temperature sensor to monitor the ambient temperature in real time, if the temperature rises abnormally, a hydraulic piston is immediately activated to push the hydraulic oil from the storage tank into the oil chamber inside the door closer, thus restoring the hydraulic function of the door closer. In the event of a fire, the door closer is restored to its damping and buffering function; in a safe environment without fire, the high damping and buffering characteristics of the door closer are eliminated, reducing the difficulty of opening and closing the fire gate. This solves the problem of high damping and difficulty in opening and closing existing fire gates due to the hydraulic buffering effect inside the door closer.

[0016] 2. By setting the first temperature sensor and the second temperature sensor, both of which are sensitive fire-fighting temperature sensors, the system monitors abnormal room temperature rise to determine whether a fire is occurring and triggers the feeding activity of the hydraulic piston propeller.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 The present invention provides an embodiment of a fire gate capable of rapid opening and closing, comprising a fire door 1, a door closer assembly 2, and a first temperature sensor 3; the door closer assembly 2 is provided on the front end face of the door panel of the fire door 1; the first temperature sensor 3 is provided on the rear end face of the door frame of the fire door 1; the door closer assembly 2 includes a door closer 201, a door closing transmission linkage 202, an oil storage tank 203, a pusher 204, a hydraulic piston pusher 205, a second temperature sensor 206, and an oil delivery channel 207.

[0024] Please see Figure 1-4In this embodiment, a door closer 201 is provided on the front end face of the fire door 1, and the outer shell of the door closer 201 is bolted to the front end face of the fire door 1; an oil storage tank 203 is provided at the lower end of the door closer 201, and the oil storage tank 203 is integrally formed with the door closer 201; a pusher 204 is provided inside the oil storage tank 203, and high-temperature resistant hydraulic oil is provided in the space between the pusher 204 and the oil storage tank 203; an oil delivery channel 207 is provided between the oil storage tank 203 and the door closer 201, and the oil delivery channel 207 is connected to the hydraulic oil cavity inside the oil storage tank 203 and the door closer 201. A hydraulic piston propulsion machine 205 is provided inside the pusher 204, and the output end of the hydraulic piston propulsion machine 205 pushes the pusher 204 to move along the inside of the oil storage tank 203; a door closer 201 is provided at the upper end of a door closing transmission link 202, and the two ends of the door closing transmission link 202 are respectively bolted to the front end of the door frame of the fire door 1 and driven to the upper end of the gear shaft inside the door closer 201; a second temperature sensor 206 is provided at the front end of the oil storage tank 203, and the second temperature sensor 206 and the first temperature sensor 3 are wirelessly connected to the electronic control unit of the hydraulic piston propulsion machine 205.

[0025] During operation, the ambient temperature is monitored in real time by the first temperature sensor 3 and the second temperature sensor 206. If the temperature rises abnormally, the hydraulic piston propeller 205 is immediately controlled to push the propeller 204 to push the hydraulic oil in the oil tank 203 into the oil chamber inside the door closer 201 along the oil delivery channel 207, thereby restoring the hydraulic function of the door closer 201. In the event of a fire, the door closer 201 is restored to a door closer 201 with damping and buffering functions. In a safe environment where no fire occurs, the high damping and buffering characteristics of the door closer 201 are removed, thereby reducing the difficulty of opening and closing the fire door 1. This solves the problem of existing fire gates, where the hydraulic buffering effect inside the door closer 201 causes high damping and difficulty in opening and closing the fire gate.

[0026] Next, the first temperature sensor 3 and the second temperature sensor 206 are both sensitive fire-fighting temperature sensors used to monitor abnormal room temperature rise to determine whether a fire is occurring and to trigger the feeding activity of the hydraulic piston propeller 205.

[0027] Through the above steps, the ambient temperature is monitored in real time by the first temperature sensor 3 and the second temperature sensor 206. Once the temperature rises abnormally, the hydraulic piston propeller 205 is immediately controlled to push the propeller 204 to push the hydraulic oil in the oil tank 203 into the oil chamber inside the door closer 201 along the oil delivery channel 207, thereby restoring the hydraulic function of the door closer 201. In the event of a fire, the door closer 201 is restored to a door closer 201 with damping and buffering functions. In a safe environment where no fire occurs, the high damping and buffering characteristics of the door closer 201 are removed, thereby reducing the difficulty of opening and closing the fire door 1. This avoids the problem of high damping and difficulty in opening and closing the fire gate caused by the hydraulic buffering effect inside the door closer 201 of the existing fire gate.
