Description

Balcony rainproof device

technical field

The utility model relates to a rainproof device, in particular to a device used on a balcony to prevent clothes from being wet by rainwater.

Background technique

In daily life, people dry their washed clothes on the balcony. The balcony of some families is open to the air. It is easy to get wet by rain. If the balcony is closed all day long, the clothes cannot be bathed in the warm sun. If things go on like this, the clothes will easily become moldy or smelly, which will be a waste.

Contents of the invention

The purpose of the utility model is to solve the problems existing in the prior art, and provide a device for preventing clothes from being wet by rainwater on the balcony.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the balcony rainproof device includes a rain sensor for sensing rain, a main control circuit connected with the rain sensor, and a transmission mechanism, which is connected to the awning connected, the main control circuit is connected with the transmission mechanism, and controls the transmission mechanism to drive the awning to rise and fall according to the signal sensed by the rain sensor.

The transmission mechanism includes a motor and a pulley connected thereto. Certainly also can adopt gear as transmission mechanism, the performance of its transmission and rotation will be more reliable.

The rain sensor is a probe. The metal probe has the characteristics of high sensitivity, which is easy to sense the falling of rainwater, and sends a detection signal to the control circuit in time, so that the control circuit can respond in time to control the awning to drop in time to keep out the wind and rain.

The main control circuit includes a relay connected with an ascending limit switch and a descending limit switch for controlling the ascending and descending of the awning.

The main control circuit also includes a manual up switch. When the switch is pressed, the awning that has been lowered will be forcibly raised, which can also ensure ventilation and lighting of the balcony in rainy days.

Compared with the prior art, the utility model has the following advantages: when it rains, the device can automatically lower the awning, block the rainwater floating into the balcony, and prevent the clothes from getting wet; when the day turns sunny, the device can automatically retract the rain The canopy, the whole device consumes low power, is safe and reliable, and has a simple and practical structure and is easy to install.

Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Embodiment one

See also shown in Figure 1, a kind of balcony rainproof device, comprises the rain sensor that senses rainwater, and the main control circuit that is connected with rain sensor, also includes transmission mechanism 2, and this transmission mechanism 2 is connected with awning, and main control The circuit is connected with the transmission mechanism 2, and the transmission mechanism is controlled to drive the awning to rise and fall according to the signal induced by the rain sensor. The transmission mechanism 2 includes a motor and a pulley connected thereto.

Please refer to Fig. 2, Fig. 2 is a schematic circuit diagram of the main control circuit, which includes a relay connected with an up limit switch and a down limit switch for controlling the up and down of the awning. In this embodiment, the rain sensor is the probe 1 . When it rains, probe 1 senses the falling of rainwater, and the rain makes the input terminal of NOT gate A be high level, the output terminal is low level, the output terminal of NOT gate B is high level, and the high level of output terminal B makes V2 conduction, the switch 4-6 of the relay J1 is connected, the motor of the transmission mechanism 2 rotates, and drives the pulley to lower the awning 3 to block the rainwater floating into the balcony. When the lower limit switch SW3 is disconnected, the motor stops rotating. After stopping, the input terminal of NOT gate A becomes low level, the output terminal becomes high level, the output terminal of NOT gate B is programmed to be low level, the high level of output terminal A makes V1 turn on, and the switch 1-2 of relay J2 When it is connected, the motor reverses, and the belt pulley is driven to automatically pull up the awning. When the ascending limit switch SW2 is disconnected, the motor stops rotating.

The main control circuit also includes a manual up switch. When the switch is pressed, the awning that has been lowered will be forcibly raised, which can also ensure ventilation and lighting of the balcony in rainy days.

The above detailed description is a specific description of the feasible embodiment of the utility model. This embodiment is not used to limit the patent scope of the utility model. Any equivalent implementation or change that does not deviate from the utility model shall be included in this case within the scope of the patent.
