However, the existing collection methods all adopt manual collection, which is high in flexibility, but have untimely property in collection time, so that the detected data are prone to have deviation, and uncertain factors of weather also bring objective influence on the collection of rainwater.

SUMMERY OF THE UTILITY MODEL

Therefore, kinds of rainwater automatic switching collecting devices need to be provided, and the problem of untimely property of existing rainwater collection is solved.

In order to achieve the purpose, the inventor provides automatic rainwater switching and collecting devices, which comprise a box body, a gate valve and a control unit, wherein a water inlet is formed in the top surface of the box body, a water outlet is formed in the side surface of the box body, a water outlet is formed in the bottom surface of the box body, the height of the water outlet is higher than that of the water outlet, the gate valve is arranged in the box body, a gate of the gate valve is located between the water inlet and the water outlet, the water inlet and the water outlet are located on the same side of the gate valve, the control unit is electrically connected with the gate valve, and the control unit is used for isolating the water outlet in.

, the control unit comprises a rain sensor and a controller, the rain sensor is electrically connected with the input end of the controller, and the output end of the controller is electrically connected with the gate valve.

, the controller is a single chip or PLC.

, the control unit further comprises a timer electrically connected to the second input of the controller.

, the device further comprises a water outlet pipe, wherein the end of the water outlet pipe is arranged on the water outlet, and the water outlet pipe is used for guiding rainwater into the materialization workshop.

Be different from prior art, above-mentioned technical scheme is when rainy day, closes the push-pull valve when detecting the rainwater through the control unit. When rainwater flows into the box body through the water inlet, the water outlet is closed or isolated by the gate valve, so that the rainwater in the box body can only flow out through the water outlet, and the rainwater is collected within 15 minutes in the early stage of rain. After 15 minutes, the control unit controls the gate valve to open the water outlet, and the water outlet is higher than the water outlet, so that rainwater entering the box body flows out through the water outlet, interference of the rainwater after 15 minutes is effectively avoided, the purpose of timely collecting the rainwater is achieved, and meanwhile the accuracy of detecting the rainwater is improved.

Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1 and 2, the embodiment provides automatic rainwater switching and collecting devices, which comprise a box body 10, a gate valve 20 and a control unit 30, wherein a water inlet 11, a water outlet 12 and a water outlet 13 are sequentially formed in the box body from top to bottom, the water inlet can be formed in the top surface of the box body, the water outlet is formed in the side surface of the box body, the water outlet is formed in the bottom surface of the box body, the gate valve is used for separating the water outlet and the water inlet into side of the gate valve, and the water outlet is formed in the other side of the gate valve, so that the box body is separated into two mutually sealed parts through the gate valve.

Specifically, the gate valve consists of a motor, a gate and a frame, wherein the gate is connected with the output of the motor through a connecting rod, a belt or a chain, so that the motor drives the gate to move in the frame when rotating, and the purpose of opening or closing the gate valve is achieved. And (3) hermetically installing the frame of the gate valve and the inner side wall of the box body, for example, adopting welding seal, rubber or silica gel gasket seal and the like, so that the frame of the gate valve is stably installed in the box body. To the control unit including rainwater inductor 31 and controller 32, for the convenience of controller control motor, the motor can be servo motor, consequently detects when having the rainwater to descend when the rainwater inductor, with the feedback information transmission to the controller of rainy day weather in, then the controller is after receiving this information, opens the motor of push-pull valve for the picture peg of push-pull valve is closed, separates the outlet seal of box, makes the rainwater that gets into in the box flow out via the delivery port, reaches the effect of collecting the rainwater.

The rainwater sensor can be an intelligent rainwater sensor which adopts a separate test circuit design and has the functions of outdoor water resistance, corrosion resistance and the like, the model specification of the intelligent rainwater sensor is EGR G5T, the working voltage is RE-5V, the protection grade is IP 62DC5V, the controller can be a single chip microcomputer or a PLC, the single chip microcomputer can be a 51 series, a 52 series or a 55 series single chip microcomputer, and the PLC can be a Western S7-1500 series PLC.

In order to accurately time the opening or closing of the gate valve, a timer 33 can be used, and the timer can be a self-contained timer in the controller or an external timer. In this embodiment, an external timer is used for timing. Specifically, when the slide valve is in a working state, the slide valve is in an open state, so that liquid entering the box body can be discharged through the water outlet. When the rainwater collection device works, the controller controls the gate valve to be closed, the timer is used for timing, the period of the timer is 15 minutes, therefore, when the time reaches 15 minutes, information is fed back to the controller, the controller controls the gate valve to be opened, the purpose of accurate timing is achieved, and therefore the accuracy and timeliness of rainwater collection are improved.
