Embodiment 1

[0050] Such as Figure 1-2 As shown, a self-resetting double-circuit safety device includes a housing 1, a panel 2 is provided on the upper surface of the housing 1, a sprocket 9 is provided on the panel 2, a driving motor is provided in the housing 1, and a driving motor main shaft 10 passes through it. The panel 2 is connected to the sprocket 9, and the sprocket 9 is connected to the chain 5, and the chain 5 drives the rope to move, thereby controlling the opening or closing of the greenhouse vent.

[0051] The panel 2 is provided with a locking device 3, and after the locking device 3 operates, the driving motor main shaft 10 is locked so that the main shaft 10 cannot rotate.

[0052] The chain 5 that is connected on the sprocket 9 forms two groups of chains 5 arranged in parallel, is provided with safety device 6 between the two groups of chains 5, is all provided with the plectrum toward safety device 6 on the two chains 5, when sprocket 9 When rotating under the drive o...

Embodiment 2

[0082] This embodiment provides a ventilator equipped with the self-resetting double-circuit safety device proposed in Embodiment 1.

[0083] The ventilator includes a ventilator body and a greenhouse vent located on one side of the ventilator body. The vent is connected to a rope, and the rope is connected to a chain 5. The drive motor spindle 10 drives the sprocket 9 to rotate, and the sprocket 9 drives the rope through the chain 5. , so as to control the opening or closing of the vent.

[0084] Using the forward or reverse rotation of the chain, the paddle on the chain drives the lever to push the corresponding contact to separate, so as to realize the cutting off of the current circuit, and ensure that the control program of the driving motor executes the opening or closing action of the vent and then cuts off the power supply, thereby Create an insurance mechanism.

[0085] The safety device is set in the middle of two groups of chains, the structure is compact and saves...

Abstract

The self-resetting double-loop safety device comprises a safety device body located on one side of a chain, a shifting piece is arranged on the side, facing the safety device body, of the chain, and the shifting piece drives a loop mechanism in the safety device body to achieve disconnection of a loop; the loop mechanisms are located on the two opposite sides of the safety device, each loop mechanism comprises a first shifting rod with one end extending out of a shell of the safety device, the other end of each first shifting rod abuts against the second contact wiring terminal, a first spring is installed on a first spring support and a spring supporting column of the first shifting rod, and the first shifting rods are tightly pressed through the first springs. Therefore, stable contact between the second contact wiring terminal and the first contact wiring terminal is ensured to realize loop closing. When the poking piece is driven by the chain to poke one end of the first poking rod, the other end of the first poking rod pushes the second contact wiring terminal to be separated from the first contact wiring terminal through the lever motion, so that the loop is disconnected. And the deflector rod drives the contact wiring terminal by utilizing the lever principle to separate the contacts to realize the disconnection of the loop, so that the ventilator has a safety function on the opening or closing of the greenhouse ventilation opening.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a self-resetting double-circuit safety device and a ventilator. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The greenhouse ventilation device (such as ventilator) in the field of agricultural planting, its working purpose is to replace manual ventilation in the greenhouse with a mechanical device, not only can directly control the switch of the vent through the panel, but also can be remotely controlled by mobile devices such as mobile phones. Controlling the switch of the vent or the fan motor saves operating time, reduces the daily greenhouse ventilation workload, avoids manual opening and closing of the vent on the top of the greenhouse, and improves the safety and convenience of the ventilation work. [0004] The greenh...
