[0045] Multiple motorized vertical walls are provided, including a first motorized vertical wall 1, a second motorized vertical wall 2, and a third motorized vertical wall 3. The first motorized vertical wall 1 and the second motorized vertical wall 2 are connected by a first Z-shaped side plate 6, and the second motorized vertical wall 2 and the third motorized vertical wall 3 are connected by a second Z-shaped side plate 7. The overlap at the joint is 100mm (L2 in the figure). The first motorized vertical wall 1 has a first side plate 4 on its side, and the third motorized vertical wall 3 has a second side plate 5 on its side. The length of a single motorized vertical wall is L1.

[0046] A first scroll 9 corresponding to the first electric vertical wall 1; a second scroll 8 corresponding to the second electric vertical wall; and a third scroll corresponding to the third electric vertical wall.

[0047] 10 smoke shields;

[0048] Bottom beam 11;

[0049] The number of drive units 14 corresponds to the number of electric vertical walls, that is, three. Each drive unit is set on one side of the corresponding electric vertical wall to drive the operation of the corresponding electric vertical wall.

[0050] Controllers 15, configured in a number corresponding to the drive devices 14, are used to control the drive devices 14.

[0051] Each controller is equipped with a control module 150. The first and second terminals of adjacent control modules are connected together, and the terminal terminals are connected to the main control box 17 to achieve unified control of multiple electric vertical walls operating simultaneously.

[0052] Wherein, the first Z-shaped side plate 6 and the second Z-shaped side plate 7 have the structure of the Z-shaped side plate 12. L3 is the height of the dropped ceiling.

[0053] In this embodiment, the driving device of each electric vertical wall is controlled by a controller. Since the driving motor is direct current, one controller cannot control multiple driving motors. In order to ensure the synchronous operation of the electric vertical wall, a module is added in each control box with a controller. The two wires on the module are connected in a loop, and the terminal is connected to the master control box. Through the fire control system or the button switch, the vertical wall can be operated simultaneously.

[0054] In a preferred embodiment, as shown in Figure 6 The combined electric smoke screen vertical wall further comprises a smoke sensor 16 arranged adjacent to the plurality of electric vertical walls, and the smoke sensor is signal connected with the master control box 17; so as to transmit the sensed smoke signal to the master control box 17.

[0055] When the smoke sensor 16 senses that the smoke mass fraction is less than 0.5%, the plurality of controllers 15 simultaneously control the smoke screen cloth 10 arranged in the plurality of electric vertical walls to drop by 0.1m;

[0056] When the smoke sensor 16 senses that the smoke mass fraction is 0.5% to 2.0%, the plurality of controllers 15 simultaneously control the smoke screen cloth 10 arranged in the plurality of electric vertical walls to drop by 0.1m to 0.4m;

[0057] When the smoke sensor 16 senses that the smoke mass fraction is 2.0% to 3.0%, the plurality of controllers 15 simultaneously control the smoke screen cloth 10 arranged in the plurality of electric vertical walls to drop by 0.4m to 0.6m;

[0058] When the smoke sensor 16 senses that the smoke mass fraction is higher than 3.0%, the plurality of controllers 15 simultaneously control the smoke screen cloth 10 arranged in the plurality of electric vertical walls to drop by 0.4m to 0.6m.

[0059] According to the size of the fire, the concentration of smoke is sensed by the smoke sensor, and then the drop height of the smoke screen cloth is controlled, so as to realize accurate smoke blocking, save resources and cost, and more effectively evacuate personnel. The concentration range can be displayed by setting the display at the position of the electric vertical wall. For example, when the smoke sensor 16 senses that the smoke mass fraction is less than 0.5%, one display light is displayed; when the smoke sensor 16 senses that the smoke mass fraction is 0.5% to 2.0%, two display lights are displayed; when the smoke sensor 16 senses that the smoke mass fraction is 2.0% to 3.0%, three display lights are displayed; and when the smoke sensor 16 senses that the smoke mass fraction is higher than 3.0%, four display lights are displayed.

[0060] In this embodiment, the control mode can be remote signal control or on-site control by firemen through buttons.

The width of each electric vertical wall is not more than 4000mm, and conventional side plates are used at the joint. If the installation space is not sufficient, the third forming mode can be used, each two electric vertical walls rotate in opposite directions and are linearly connected, and operate in opposite directions. The smoke-proof cloth is overlapped by 100mm to prevent smoke leakage, and the installation space of each electric vertical wall is saved, only 100mm high space is needed. The width of each vertical wall is not more than 4000mm, and Z-shaped side plates are used at the joint. Different combinations can be applied to different installation spaces. Where the installation space is sufficient, the upper and lower joint combination can be used.
