Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 2 is a schematic structural diagram of a control portion of a blower wall system according to an embodiment of the present application, and fig. 3 is a schematic structural diagram of a blower wall system according to an embodiment of the present application, and as shown in fig. 2 and fig. 3, the blower wall system 1 includes:
a fan wall having a plurality of fans 11;
the air return preventing device 12 is provided with a plurality of air return preventing devices 12, the number of the air return preventing devices 12 is the same as that of the plurality of fans 11, the plurality of air return preventing devices 12 are correspondingly arranged at the air inlets of the plurality of fans 11 one by one, the air return preventing devices 12 have a first state and a second state, and can be switched between the first state and the second state, when the air return preventing devices 12 are switched to the first state, the air inlets are exposed by the air return preventing devices 12, or when the air return preventing devices 12 are switched to the second state, the air inlets can be blocked by the air return preventing devices 12;
the controller 13 is configured to acquire an operation state signal of each of the fans 11, and send a first control signal to the return air preventing device 12 corresponding to a certain fan 11 when the operation state signal of the certain fan 11 indicates that the certain fan 11 is in a failure, so that the return air preventing device 12 corresponding to the certain fan 11 is switched to the second state after receiving the first control signal.
In fig. 3, the following situation is shown: the air return preventing devices 12 in the middle of the upper row are in the second state, and the rest air return preventing devices 12 are in the first state.
Specifically, in practical applications, each fan 11 is normally operated normally, and each air return preventing device 12 may be in the first state in the initial state, so that the air inlet of each fan 11 is exposed. The operation of each fan 11 on the fan wall is controlled through the controller 13, and each fan 11 rotates to form air outlet. In the operation process of each fan 11, the controller 13 obtains the operation status signal of each fan 11, each fan 11 normally operates, and accordingly, the operation status signal of each fan 11 indicates that the operation is normal, and in the case of normal operation of the fan 11, the controller 13 does not control each air return preventing device 12, so that each air return preventing device 12 is kept in the first state.
In practical applications, the plurality of fans 11 on the fan wall may be arranged in a matrix form, for example, the fan wall shown in fig. 3 can improve the uniformity of the wind field. Each fan 11 on the fan wall is at the operation in-process, because of various reasons, when certain fan 11 broke down, this fan 11 stall that breaks down, this fan 11's that breaks down wind channel has become uncontrolled ventilation duct, if do not carry out the shutoff to this fan 11's that breaks down wind channel, the wind that comes out from other normal fans 11 of operation on the fan wall, the wind channel backward flow that the part can go out through fan 11 that breaks down, this is adverse effect to air supply efficiency and air supply amount of wind. And through the above-mentioned embodiment scheme of this application, each fan 11 on the fan wall is at the operation in-process, controller 13 acquires the running state signal of each fan 11, when the running state signal instruction of certain fan 11 is for breaking down, show this certain fan 11 stall, trigger from this and control the air return preventing device 12 that this certain fan 11 corresponds, switch it to the second state, make air return preventing device 12 can shutoff the air intake of this certain fan 11, thereby help preventing the wind that comes out from the normal fan 11 of fan wall operation, the wind channel through trouble fan 11 flows back and goes out, and then help reducing the adverse effect of fan wall air supply efficiency and air supply amount.
Further, the controller 13 is further configured to:
when the operation state signal of the certain fan 11 indicates that the certain fan 11 operates normally again, a second control signal is sent to the air return preventing device 12 corresponding to the certain fan 11, so that the air return preventing device 12 corresponding to the certain fan 11 is switched to the first state after receiving the second control signal.
Specifically, in practical application, after the failure of the failed fan 11 is removed, the failed fan 11 operates normally again, and when the controller 13 acquires that the operating state signal indicates that the operation is normal again, the controller controls the air return preventing device 12 corresponding to the failed fan 11 to switch to the first state, so that the air inlet of the failed fan 11 is exposed again, and the air supply efficiency and the air supply volume after the failed fan 11 operates again are not affected.
Further, before the step of sending the first control signal to the air return preventing device corresponding to the certain fan is executed, the controller is further configured to:
acquiring running state signals of other fans 11;
if the operating state signals of the other fans 11 do not all indicate that a fault occurs, the step of sending the first control signal to the air return preventing device 12 corresponding to the certain fan 11 is executed.
Specifically, when the operating state signal of a certain fan 11 indicates that a failure occurs, the controller 13 does not immediately perform the step of switching the air return preventing device 12 corresponding to the certain fan 11 to the second state, but first confirms the operating states of the other fans 11 on the fan wall, and if all the other fans do not fail, it can be confirmed whether the failure is caused by the certain fan 11 itself, for example, the quality cause of the failure itself, and when it is confirmed that part of or all the other fans 11 operate normally, it can be said that the failure of the certain fan 11 is caused by the failure itself to some extent, in this case, it is allowed to perform switching the air return preventing device 12 corresponding to the certain fan 11 to the second state.
The following is further explained by specific application examples, for example, six fans are arranged on the fan wall, and the six fans are respectively: specifically, referring to the schematic in fig. 3, when the controller 13 acquires that the operating state signal of the fan a indicates that a fault occurs, the air return preventing device 12 corresponding to the fan a is not switched to the second state immediately, but the operating state signals of the fan B, the fan C, the fan D, the fan E, and the fan F are confirmed first. The following three cases are the confirmation results: first, the operating state signals of the five fans B, C, D, E and F indicate normal operation, which may indicate that the failure of the fan a is caused by itself, and in the case where it is determined that the failure of the fan a is caused by itself, the air return preventing device 12 corresponding to the fan a is allowed to be switched to the second state. Secondly, in the five fans 11, namely the fan B, the fan C, the fan D, the fan E and the fan F, part of the operation state signals indicate normal operation, for example, the operation state signals of the fan C, the fan D, the fan E and the fan F indicate normal operation, and the operation state signal of the fan B indicates that a fault occurs, for this case, before the fan a fails, the fan B fails, and the fault of the fan B has not been eliminated, and the operation state signals of the fan C, the fan D, the fan E and the fan F indicate normal operation, it can also be said that the fault of the fan a is caused by itself, and in this case, the return air preventing device 12 corresponding to the fan a is allowed to be switched to the second state. The third is that, the running state signals of five of the fan B, the fan C, the fan D, the fan E and the fan F all indicate that the fault occurs, it can be seen that six fans 11 all have the fault, it can be explained to a certain extent that other reasons have caused the fault of the six fans 11, and meanwhile, under the condition that the fault occurs to all the six fans 11, the fan wall cannot realize air supply, under the condition, the purpose that the air return prevention can not be realized by controlling the air return prevention device 12 to be switched to the second state is realized, so that the air return prevention device 12 is not required to be controlled to be switched to the second state.

Specifically, the above-described related embodiment is further explained below by means of fig. 3 and 4. Normally, each fan 11 is normally operated, and the normal state of each air returning prevention device 12 may be a first state, so that the air inlet of each fan 11 is exposed, and in fig. 3, the following situation is shown: the air return preventing device 12 in the middle of the upper row is in a second state, namely the fan breaks down, the air inlet of the fan is blocked by the air return preventing device, and the rest air return preventing devices 12 are in a first state, namely the air return preventing devices expose the air inlet of the fan. Referring to fig. 3 and 4, in a normal state, the first switch door 103 and the second switch door 104 are in a first state, that is, they are far away from each other, so that wind can smoothly enter the wind inlet, and in this state, the first spring 1004 and the second spring 1005 are kept in a natural telescopic state. When a fan fails, the controller sends a first control signal to the failed fan, so that the failed fan rotates to pull the first steel rope 1002 and the second steel rope 1003, and the first switch door 103 and the second switch door 104 move in opposite directions to form a second state, referring to the state of the air return preventing device 12 in the middle of the upper row in fig. 3, in this state, the first spring 1004 and the second spring 1005 are stretched due to the opposite movement of the first switch door 103 and the second switch door 104, and form a retraction elastic driving force. When the fan failure is eliminated, the controller sends a second control signal to the motor 1001, so that the motor 1001 is in a free state, that is, the motor 1001 releases the pulling force on the first switch door 103 and the second switch door 104, at this time, under the respective retracting elastic driving forces of the first spring 1004 and the second spring 1005, the first switch door 103 and the second switch door 104 perform a back-to-back motion, and when the first spring 1004 and the second spring 1005 change to a natural telescopic state again, the first state is formed between the first switch door 103 and the second switch door 104.
In another embodiment, in both the first driving portion and the second driving portion, when the first driving portion is used to drive the first switching door 103 to move and the second driving portion is used to drive the second switching door 104 to move, and the first switching door 103 and the second switching door 104 are driven to move in opposite directions or in opposite directions by the simultaneous driving of the first driving portion and the second driving portion, the first driving portion and the second driving portion both adopt a reciprocating mechanism.
