Description

Intelligent rolling gate with function of stopping when encountering blockage

Technical Field

The utility model belongs to the shutter door field, specifically speaking are intelligent shutter door with meet and hinder the stop function.

Background

At present, in the closing process of a rolling gate, if a barrier blocks the closing of the rolling gate, the rolling gate can continuously move downwards to be closed, the rolling gate can be damaged, and particularly, safety accidents can be caused when people or vehicles pass through the rolling gate when the rolling gate is closed. Therefore, there is a patent with chinese published application No. 200920236228.5 that discloses a remote control meets and hinders stop device, has set up meeting at the shutter door and hinders trigger line and trigger device, meets through two and hinders trigger line perception shutter door and meets and hinder and send stop signal to the shutter door motor by trigger device, concrete action is meeting and hinders the trigger line and receive external force extrusion and contact each other when meeting, trigger circuit switches on, avoided the shutter door to close the door and met the damage that hinders the in-process and probably cause, but there is the following problem: 1) the trigger circuit is electrified and triggered under the condition of being extruded by a resistance trigger line, so that the micro change generated when the shutter door is just contacted with an obstacle cannot be sensed in time, and the trigger circuit can be conducted only under the condition of relatively obvious deformation; 2) if the installation of the blocking trigger line is too loose, the sensitivity of the blocking trigger line is not high, and the barrier cannot be detected in time. When the two situations occur, the rolling door is often contacted with the barrier to a certain degree and then is treated, which is obviously not timely enough.

Fig. 1 is a schematic view of the present invention.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in the accompanying drawing 1, the utility model discloses an intelligence shutter door with meet and hinder shutdown function, including rolling slats door 2 and guide rail 1, the side of rolling slats door 2 is installed in

guide rail

1, and 2 tops of rolling slats door are equipped with install bin 7, are equipped with spool 5 in the install bin 7, and rolling slats door 2 convolutes on spool 5, and spool 5 is connected with

motor

4, 2 bottoms of rolling slats door are equipped with floorbar 12, are equipped with pressure sensor 13 on the floorbar 12, and pressure sensor 13 is connected with the controller 8 of establishing in install bin 7, and controller 8 is connected with motor 4, and motor 4's inlet wire end connects the power supply line, and this power supply line facial make-up has connect pressure relay, and this pressure relay is connected with pressure sensor. In the process of descending and closing the door of the rolling door, if the rolling door encounters an obstacle, the pressure applied to the pressure sensor is increased, the rolling door is extruded downwards continuously along with the continuous running of the motor, and when the pressure sensor detects that the pressure value is greater than a set value, a signal is transmitted to the controller, the controller immediately controls the motor to stop running, so that the rolling door is prevented from descending without limitation, and the motor is protected. Meanwhile, the pressure relay is utilized, when the pressure value detected by the pressure sensor is larger than the power supply value, the pressure relay is automatically disconnected, the power supply is stopped, and the double guarantee is formed with the controller.

The pressure sensor is provided with the protection pad, the protection pad is utilized to protect the pressure sensor, the pressure sensor is prevented from being damaged by other objects, and the service life of the pressure sensor is prolonged.

And an alarm 6 connected with the controller is arranged in the installation box 7. After the motor is disconnected from running, the controller controls the alarm to start alarming, the alarm is usually a buzzer alarm and sounds, attention is improved, obstacles are timely discharged, and damage to the roller shutter door is avoided.

The installation box 7 is also internally provided with a timer 9 connected with the controller 8, the pressure sensor 13 transmits the detected pressure to the controller 8, and the controller calculates the maintenance time of the detected pressure through the timer 9. After detecting that the pressure of the pressure sensor is larger than a set value, the controller starts a timer to start timing, and checks the time for maintaining the pressure. For example, a time limit of 15 seconds may be preset, and after the controller disconnects the operation of the motor, if the pressure detected by the pressure sensor within 15 seconds is still greater than the set pressure value, the automatic reset is not performed. If the pressure detected by the pressure sensor within 15 seconds is recovered to be normally smaller than the set pressure value, the controller automatically starts the motor to drive the roller shutter door to descend and close the door again.

The rolling door 2 is further provided with a resistance triggering line 11 which is arranged along the door closing direction of the rolling door in a tightening mode, the resistance triggering line 11 is connected with a contact of a micro switch 10 arranged in the installation box 7, and the micro switch is connected with the controller. Through this meet and hinder the trigger line, carry out dual guarantee. The microswitch may be set to be more sensitive than the pressure sensor. When the rolling door is in a descending and closing process with an obstacle, the rolling door is in slight deformation when being contacted with the obstacle, the resistance-encountering trigger line in a tense state is loosened, once the resistance-encountering trigger line is loosened, the acting force between the action spring on the micro switch contact and the resistance-encountering trigger line is reduced, the touch switch can sense the change of the small acting force, generally speaking, as long as the critical point of 0.07 N.M is reached, the action spring of the touch switch can generate instantaneous action to change the conducting state of the contact at the tail end of the action reed, and simultaneously, a signal is sent to the controller to control the motor to stop rotating through the controller.

In the above, if the combination of the resistance-encountering trigger line and the micro switch fails, the stop operation of the motor can be realized by using the mechanism of the pressure sensor, and the two are combined and used.

It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
