[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] like Figure 1-Figure 3 As shown, the utility model proposes a fan operation monitoring device for a laying hen farm, which includes:

[0035] A fan detection component, a power supply detection component and a controller 130, wherein the fan detection component and the power supply detection component are electrically connected to the controller 130 respectively;

[0036] The fan detection assembly includes a bracket 110 fixedly mounted on the main body of the fan 100, the bracket 110 is rotatably connected to a connecting rod 111, one end of the connecting rod 111 is connected to a wind shield 112, the wind shield 112 cooperates with the fan 100, a position sensor 113 is mounted on the bracket 110, the position sensor 113 cooperates with the other end of the connecting rod 111, and the position sensor 113 is electrically connected to a controller 130;

[0037] The power supply detection component includes an intermediate relay 120 , a control circuit of the intermediate relay 120 is electrically connected to a power supply circuit of the fan 100 , and a contact of the intermediate relay 120 is electrically connected to a controller 130 .

[0038] Furthermore, the bracket 110 is fixedly mounted on the mesh cover 101 at the air outlet of the fan 100 .

[0039] Furthermore, in the initial state, the plane where the wind shield 112 is located is perpendicular to the air supply direction of the fan 100 .

[0040] In this embodiment, the fan detection component is used to detect whether the fan is operating normally, that is, whether there is an abnormal stop problem, such as belt breakage, and the power supply detection component is used to detect whether the power supply of the fan is normal, that is, whether there is a power outage or phase loss problem.

[0041] The fan detection component is arranged on the air supply passage of the fan 100. Specifically, the fan detection component is installed at the air outlet of the fan 100. The bracket 110 is fixedly installed on the mesh cover 101 of the air outlet of the fan 100. The fan detection component determines whether the fan 100 is operating normally by sensing the air supply airflow of the fan 100.

[0042] The power supply detection component includes an intermediate relay 120, a control circuit of the intermediate relay 120 is electrically connected to the power supply circuit of the fan 100, and a contact of the intermediate relay 120 is electrically connected to the controller 130. Specifically, according to different models of the fan 100, its power supply circuit is divided into 220V single-phase AC and 380V three-phase AC. When 220V single-phase AC is used, there is one intermediate relay 120, and the intermediate relay 120 is set on the live wire. When 380V three-phase AC is used, there are three intermediate relays 120, and the three intermediate relays 120 are respectively set on the three phase lines A, B, and C of the 380V three-phase AC. When the power supply circuit is in an abnormal state such as power failure or phase loss, the pull-in state of the intermediate relay 120 on the corresponding line changes, thereby changing the level of the contact of the intermediate relay 120. The controller 130 determines whether the power supply is normal by judging the change of the contact level of the intermediate relay 120. The selection, wiring and use of the intermediate relay 120 belong to the prior art and will not be described in detail in this embodiment.

[0043] In the initial state, the plane where the wind shield 112 is located is perpendicular to the air supply direction of the fan 100 . At this time, the wind shield 112 is closest to the mesh cover 101 .

[0044] Taking the fan 100 powered by 380V three-phase AC power as an example, the specific working process of the utility model is explained. In the initial state, after the fan 100 is started, the fan 100 generates a high-pressure airflow, which is discharged from the air outlet of the fan 100 and blows the wind shield 112, so that the wind shield 112 is away from the air outlet of the fan 100, and the wind shield 112 drives the connecting rod 111 to rotate around the hinge point between the connecting rod 111 and the bracket 110, so that the end of the connecting rod 111 away from the wind shield 112 is close to the bracket 110, and the relative distance between the end of the connecting rod 111 away from the wind shield 112 and the position sensor 113 changes, and the position sensor 113 converts the relative distance signal into a corresponding electrical signal and sends it to the controller 130. The controller 130 is provided with a corresponding control program. The controller 130 determines whether the operation of the fan 100 is normal after processing by the control program. When it is determined that an abnormal situation occurs, the staff is notified in time.

[0045] After the fan 100 is started, the intermediate relays 120 on the three phase lines A, B, and C respectively detect the status of the three phase lines A, B, and C in real time. When the power supply circuit is powered off or one of the phase lines is in an abnormal state such as phase loss, the attraction state of the intermediate relay 120 on the corresponding line changes, thereby changing the level of the contacts of the intermediate relay 120. The controller 130 is provided with a corresponding control program. The controller 130 determines whether the power supply is normal after processing by the control program. When it is determined that an abnormal situation occurs, the staff is notified in time.

[0046] It should be specially noted that the control program in the controller 130 belongs to the prior art, and its control logic and program content can be easily obtained from the Internet and the user manual, and will not be described in detail in this embodiment.

[0047] Through the fan detection component and the power supply detection component, it is possible to timely and effectively detect whether the fan power supply line and the status of the fan are normal. When an abnormal situation occurs, an alarm will be given in time to assist workers to quickly troubleshoot, thereby ensuring the safe production of laying hen farms.

[0048] like Figure 1-7 As shown, in one embodiment of the fan operation monitoring device for a laying hen farm of the utility model,

[0049] Furthermore, the position sensor 113 includes an inductive proximity switch, and the position sensor 113 is disposed between the bracket 110 and the connecting rod 111 .

[0050] Furthermore, a spring 114 is provided between the connecting rod 111 and the bracket 110 , one end of the spring 114 is connected to the bracket 110 , and the other end of the spring 114 is connected to the connecting rod 111 .

[0051] Furthermore, the length of the wind shield 112 is 50-100 mm, and the width of the wind shield 112 is 50-100 mm.

[0052] Furthermore, the material of the windshield 112 includes galvanized iron plate.

[0053] Furthermore, the number of intermediate relays 120 includes three, the power supply circuit of the fan 100 includes a three-phase power supply circuit, the A1 ends of the three intermediate relays 120 are respectively connected to the phase lines of phase A, phase B and phase C of the power supply circuit, the A2 ends of the three intermediate relays 120 are respectively connected to the neutral line of the power supply circuit, and the contacts of the three intermediate relays 120 are respectively electrically connected to the controller 130.

[0054] Furthermore, the controller 130 includes a PLC controller.

[0055] Furthermore, the controller 130 is electrically connected to a display screen.

[0056] Furthermore, the controller 130 is electrically connected to a speaker 132 .

[0057] In this embodiment, the position sensor 113 is electrically connected to the controller 130 , the connecting rod 111 cooperates with the position sensor 113 , and the position sensor 113 senses and measures the relative distance between the end of the connecting rod 111 away from the windshield 112 and the position sensor 113 .

[0058] A spring 114 is also provided between the connecting rod 111 and the bracket 110. When the fan 100 starts to blow the wind shield 112, the spring 114 is deformed to provide an opposite force to the connecting rod 111 and the wind shield 112. On the one hand, the stability of the connecting rod 111 and the wind shield 112 during rotation is ensured. On the other hand, the deformation amount and the elastic force generated by the spring 114 are different due to the different wind force and wind speed when the fan 100 is blowing out, so that the distance between the position sensor 113 and the connecting rod 111 is different, thereby generating electrical signals of different sizes, thereby improving the measurement accuracy of the position sensor 113.

[0059] In this embodiment, the fan 100 includes a motor 102, and the motor 102 drives the fan blades 104 to rotate through the conveyor belt 103. When the conveyor belt 103 breaks, causing the fan blades 104 to stop rotating, the spring 114 plays a resetting role. Under the action of the spring 114, the connecting rod 111 and the wind shield 112 move in the opposite direction and reset. According to the electrical signal feedback from the position sensor 113 at this time, the controller 130 issues an alarm.

[0060] It should be noted that, in this embodiment, the fan 100 is powered by 380V three-phase AC power, and the fan 10 is provided with a power supply cabinet, such as Figure 7 As shown, in addition to the basic air switches, energy meters, leakage protectors and other common equipment, the power supply cabinet is also provided with corresponding terminal blocks, on which various electrical signals such as the position sensor 113, the main power supply circuit breaker, and the speaker can be led out. A voltage signal is taken from the output terminals A phase, B phase, and C phase of the main power supply circuit breaker of the fan cabinet, respectively, and then connected to the A1 terminals of the coils of the three AC 220V intermediate relays respectively. The A2 terminals of the three intermediate relays are connected in parallel and connected to the neutral line; the contacts of the three intermediate relays are connected to the input terminal of the PLC controller.

[0061] When in use, the fan 100 blows the wind shield 112. Under the action of the wind shield 112, the connecting rod 111 rotates, the distance between the connecting rod 111 and the position sensor 113 changes, and the inductance between the connecting rod 111 and the position sensor 113 changes. The controller 130 obtains the electrical signal fed back by the position sensor 113, and determines whether the fan 100 is operating normally after judgment.

[0062] After the fan 100 is started, the intermediate relays 120 on the three phase lines A, B, and C respectively detect the status of the three phase lines A, B, and C in real time. When the power supply circuit is in abnormal conditions such as power failure or phase loss, the attraction state of the intermediate relay 120 on the corresponding line changes, thereby changing the level of the contact of the intermediate relay 120. The controller 130 determines whether the power supply is normal by judging the change in the contact level of the intermediate relay 120. If an abnormality occurs, the staff is notified in time.

[0063] The controller 130 is electrically connected to a display screen, which displays the fan operating status screen, including normal or stopped, broken belt, etc. When power outage, phase loss or broken belt occurs, the PLC controller sends an alarm signal. At this time, the display screen displays the corresponding alarm information, and the speaker 132 sounds to prompt, assisting workers to quickly troubleshoot, and realize real-time monitoring of the fan 100's operating status around the clock, and rapid alarms for broken belts, power outages, phase loss, and abnormalities, etc., reducing manual inspections or night inspections, improving the internal environmental quality and temperature control effect of the breeding house, improving the efficiency and safety of laying hen breeding, and bringing high returns to users.

[0064] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
