Description

Technical Field

[0001] The invention relates to a safe electromagnetic locking device for automatic fireproof rolling shutter doors in a logistics workshop, belonging to the technical field of fire safety automation. Background Art

[0002] The rolling shutters in workshops on the market are all manually controlled. When a fire occurs, the workers' first reaction is to escape, and they have no time to take care of the safety of the workshop, which causes the fire to continue to expand and cause significant losses to people's lives and property.

[0003] Traditional fire shutter doors need to be lowered manually. When a fire breaks out, workers have to use the time they need to escape to manually close the fire shutter doors, which is very dangerous and inconvenient to operate. In addition, when the fire occurs close to the fire shutter doors, workers cannot get close to the shutter doors and are unable to lower them.

[0004] In addition, the automatic control of traditional fire shutter doors is integrated through the smoke alarm system. In the event of a fire, the synchronous closing of the fire shutter will seriously affect the safe evacuation of personnel. If an electrical fire occurs and the circuit is damaged, the fire shutter will be unable to close.

[0005] However, smoke concentration is not the only indicator that can be used to determine whether a fire has occurred. Temperature rise, flames, etc. can also be used to determine whether a fire has occurred. Once the smoke alarm fails, it will cause significant loss of life and property. Therefore, the prior art uses temperature sensors to detect the temperature in the workshop to detect fires in time and control the lowering of fire shutters through a controller. However, the existing temperature sensors require an external power supply. When an electrical fire occurs, the temperature sensors may fail. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a safe electromagnetic locking device for automatic fireproof rolling shutter doors in logistics workshops to solve the problem that the fireproof rolling shutter cannot be closed due to circuit damage caused by electrical fire, which causes the temperature sensor to fail.

[0007] The technical solution adopted by the present invention is: a safe automatic fireproof rolling shutter door for a logistics workshop, comprising a frame, a fireproof rolling shutter door, a temperature control mechanism and a battery, wherein a rotating shaft with an axis arranged in a horizontal direction is fixed on the frame, the fireproof rolling shutter door is wound on the rotating shaft, and the rotating shaft is driven by a motor fixed on the frame; the battery is fixed on the frame, and the motor is electrically connected to the battery; the temperature control mechanism comprises a metal shell, a slide plate is slidingly and sealedly connected to the inside of the metal shell, and the slide plate is connected to one end of the metal shell through a spring; the inside of the metal shell is filled with temperature-sensitive particles at one end close to the spring; a cavity is opened on the side wall of the metal shell, and the cavity is connected to the end of the inside of the metal shell close to the spring; a manual switch of the motor is fixed on the outer wall of the motor, the manual switch passes through the side wall of the metal shell connected to the spring, and the manual switch extends to the inside of the metal shell.

[0008] Preferably, a small door is provided at the lower portion of the fireproof rolling shutter door, and a small door curtain is connected to the small door.

[0009] Preferably, the top of the small door curtain is fixed to the top of the small door through a fixing strip, the two side edges and the bottom edge of the small door curtain are fixed with a first magnet, the two side frames and the bottom frame of the small door are fixed with a second magnet, and the first magnet and the second magnet attract each other.

[0010] Preferably, a counterweight is fixed to the lower end of the fireproof rolling shutter door.

[0011] Preferably, the fireproof rolling shutter door is made of inorganic fiber material.

[0012] Preferably, sealing strips are fixed on both sides of the fireproof rolling shutter door.

[0013] Preferably, the sealing strip is a high temperature resistant rubber strip.

[0014] Preferably, an infrared receiver is fixed on the rack, the infrared receiver is paired with an infrared transmitter, the infrared transmitter is fixed on a remote controller, and the infrared receiver is electrically connected to the motor through a controller.

[0015] Beneficial effects of the present invention:

[0016] 1. Compared with the traditional fireproof rolling shutter, the automatic control of the traditional fireproof rolling shutter is comprehensively controlled by the alarm system. When a fire occurs, if an electrical fire occurs at the same time and the line is damaged, the fireproof rolling shutter will not be able to be closed; while in the present invention, the motor and the equipment in the workshop do not share the power supply, and the motor is powered by a separate battery, thereby avoiding the situation where the fireproof rolling shutter door cannot be closed when an electrical fire occurs.

[0017] 2. Compared with traditional fire shutters, the automatic control of traditional fire shutters is comprehensively controlled by an alarm system, and the synchronous closing of the fire shutters will seriously affect the safe escape of personnel; in this application scheme, a small door and a small door curtain are set on the fire shutter door. After the fire shutter door is closed, the staff can escape in an orderly manner through the small door.

[0018] 3. Compared with traditional fireproof roller shutters, the automatic control of traditional fireproof roller shutters is comprehensively controlled through an alarm system; in the present application, the staff can use a remote control to remotely control the motor to lower the fireproof roller shutter door, thereby avoiding the aggravation of the fire caused by the untimely lowering of the fireproof roller shutter door. At the same time, the on-site control of the staff is eliminated, providing further protection for personal safety and buying more time for the evacuation of personnel.

[0019] 4. In particular, compared with traditional fireproof rolling shutters, the automatic control of traditional fireproof rolling shutters is comprehensively controlled by an alarm system; while the present invention uses the temperature rise after a fire in the workshop to cause the solid temperature-sensitive particles to melt into liquid, and the slide plate slides in the direction close to the manual switch under the action of the spring, and the slide plate squeezes the liquid after the temperature-sensitive particles melt into the cavity. The slide plate can be pressed to the manual switch of the motor under the action of the spring, and the manual switch rotates the motor to lower the fireproof rolling shutter door, providing a new way to achieve the lowering of the fireproof rolling shutter door, that is, the lowering of the rolling shutter door is triggered according to the temperature rise inside the workshop, and the fireproof rolling shutter door can be automatically lowered when the staff is not on site or the staff has not discovered the fire; even after discovering the fire, the staff does not need to get close to the fire point at all and can escape directly to the outside.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1:

[0024] A safe automatic fireproof rolling shutter door for a logistics workshop comprises a frame, a fireproof rolling shutter door 12, a temperature control mechanism 20 and a storage battery 30.

[0025] like Figure 1As shown, a motor with an axis arranged in the horizontal direction is fixed on the frame, the motor is a servo motor, the servo motor can rotate forward and reverse, the output shaft of the motor is arranged horizontally to the right, a rotating shaft 11 is fixed on the output shaft of the motor, the axis of the rotating shaft 11 is arranged in the horizontal direction, a fire shutter door 12 is wound on the rotating shaft 11, the upper end of the fire shutter door 12 is fixed on the rotating shaft 11, and the lower end of the fire shutter door 12 is a free end.

[0026] The motor drives the rotating shaft 11 to rotate forward, and the rotating shaft 11 lowers the fire shutter door 12 wound on the rotating shaft 11; the motor drives the rotating shaft 11 to rotate reversely, and the rotating shaft 11 rolls up the fire shutter door 12, thereby realizing the automatic retraction and release of the fire shutter door 12. The fire shutter door 12 in this embodiment is made of inorganic fiber material, which is fire-resistant and high-temperature-resistant.

[0027] like Figure 1 As shown, a rectangular counterweight 14 is fixed to the lower end of the fire shutter door 12. The counterweight 14 is made of high-temperature resistant stainless steel. When the fire shutter door 12 is lowered, the counterweight 14 can accelerate the descent of the fire shutter door 12 and ensure that the fire shutter door 12 descends vertically.

[0028] like Figure 1 As shown, rectangular sealing strips 13 are fixed on the left and right sides of the fire shutter door 12. The sealing strips 13 are high temperature resistant rubber strips. After the fire shutter door 12 is lowered, the sealing strips 13 cooperate with the existing grooves on the wall to seal, preventing the smoke inside the workshop from spreading to the outside and causing suffocation to the operators.

[0029] like Figure 1 As shown, a rectangular small door 15 is opened at the lower right part of the fireproof rolling shutter door 12, and a small door curtain 16 is connected to the small door 15. The top of the small door curtain 16 is fixed to the top of the small door 15 by a fixing strip 17. The left and right side edges and the bottom edge of the small door curtain 16 are fixed with a first magnet, and the left and right side frames and the bottom frame of the small door 15 are fixed with a second magnet. The first magnet and the second magnet attract each other, so that the small door curtain 16 can be opened relative to the small door 15. When the fireproof rolling shutter door 12 is closed, the people trapped in the workshop are allowed to escape in an orderly manner through the small door 15.

[0030] This embodiment also includes an infrared receiver, which is fixed on the frame. The infrared receiver is paired with an infrared transmitter, which is fixed on the remote controller. The infrared receiver is electrically connected to the motor through the controller.

[0031] When the staff finds a fire, they can use the remote control to make the infrared transmitter emit infrared rays, and after the infrared receiver receives the signal, the controller rotates the motor to lower the fireproof rolling shutter door 12.

[0032] like Figure 1As shown, the battery 30 is fixed on the frame, and the output end of the battery 30 is connected to the input end of the motor through a wire; the motor is powered by the battery 30. A manual switch 101 for starting the motor is fixed at the upper end of the motor, and the contact point of the manual switch 101 is arranged vertically upward.

[0033] like Figure 2 As shown, the temperature control mechanism 20 includes a rectangular metal shell 21, the axis of the metal shell 21 is arranged in the vertical direction, the metal shell 21 is hollow, and the metal shell 21 is slidably and sealedly connected with a slide plate 22 arranged in the horizontal direction. The lower end of the slide plate 22 is connected to the bottom of the metal shell 21 through a spring 23; the part of the metal shell 21 below the slide plate 22 is filled with temperature sensitive particles 24; a cavity is opened at the lower part of the side wall of the metal shell 21, and the cavity is connected to the bottom of the metal shell 21; the manual switch 101 vertically penetrates the bottom of the metal shell 21 upward, and the manual switch 101 extends to the inside of the metal shell 21.

[0034] Under normal circumstances, the solid temperature-sensitive particles 24 and the slide plate 22 are located on the top of the metal shell 21 and stretch the spring 23, and the spring 23 stores energy. When a fire occurs, the ambient temperature rises to melt the solid temperature-sensitive particles 24 into liquid, and the slide plate 22 moves downward under the action of the spring 23. The slide plate 22 squeezes the melted liquid of the temperature-sensitive particles 24 into the cavity, and the slide plate 22 continues to move downward and presses the manual switch 101 of the motor, and the motor rotates to lower the fireproof rolling shutter door 12. The principle of the temperature control mechanism 20 is similar to the working principle of the thermal fuse (SF type) in the prior art.

[0035] The specific implementation process is as follows:

[0036] When a fire occurs, the staff can use the remote control to make the infrared transmitter emit infrared rays, and after the infrared receiver receives the signal, the controller rotates the motor to lower the fireproof rolling shutter door 12.

[0037] After the fireproof rolling shutter door 12 is lowered, if there are staff members locked inside the workshop, the staff members locked inside the workshop can escape through the small door 15, and the employees outside the workshop can escape directly without having to approach the fire source.

[0038] If the staff fails to discover the fire in time, the fire will increase the ambient temperature, and the solid temperature-sensitive particles 24 will melt into liquid. The slide plate 22 will move downward under the action of the spring 23, and the slide plate 22 will squeeze the melted liquid of the temperature-sensitive particles 24 into the cavity. The slide plate 22 will continue to move downward and press the manual switch 101 of the motor, and the motor will rotate to lower the fire shutter door 12.

[0039] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
