In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The automatic drain device for collecting rainwater in a plant area according to the embodiment of the utility model is specifically described below with reference to fig. 1 to 2.

As shown in fig. 1 and 2, the automatic drain device for collecting rainwater in a plant area according to the embodiment of the present invention includes: reservoir 102, float switch 106, self-priming pump 108, time delay, etc. The water reservoir 102 is communicated with the plant sewer 104, and the depth of the water reservoir 102 is lower than the bottom height of the plant sewer 104, so that accumulated water can be discharged after being collected to the water reservoir 102. A float switch 106 is mounted on the inside wall of the reservoir 102 to facilitate control of the start and stop of the self priming pump 108 based on the fluid level within the reservoir 102. Self priming pump 108 is installed subaerial near cistern 102 pool mouth, and self priming pump 108's access connection inlet channel 110, inlet channel 110 extend to cistern 102's bottom, have set gradually flexible coupling 116, stop valve 118 and filter 120 between self priming pump 108's import and inlet channel 110, have reduced impurity and have got into self priming pump 108 and lead to the emergence of self priming pump 108 damage phenomenon, are favorable to prolonging self priming pump 108's life. The outlet of the self-priming pump 108 is connected with a water outlet pipeline 112, the water outlet pipeline 112 extends to the outside of the factory, and a stop valve 118 and a pressure gauge 122 are sequentially arranged between the outlet of the self-priming pump 108 and the water outlet pipeline 112. Connect delay unit in self priming pump 108's control circuit, delay unit is time relay 114, and float switch 106 is connected with time relay 114, time relay 114's normally open contact is established ties to self priming pump 108's control circuit in, time relay 114's normally closed contact is connected with float switch 106, when reaching certain liquid level like this, float switch 106 is closed, can trigger time relay 114, after the time delay, time relay 114's normally closed contact disconnection, normally open contact is closed, thereby start self priming pump 108, the time delay of having realized self priming pump 108 starts, even float switch 106 receives rivers wave influence frequent action, can not lead to frequent opening of self priming pump 108 yet, the life of self priming pump 108 has been prolonged, the maintenance frequency has been reduced. The automatic factory rainwater collecting and discharging device effectively solves the problem of water accumulation in a factory, rainwater is not easy to overflow a sewer even if the water amount is large in rainy season in summer, and the phenomenon that the road surface of the factory is submerged by rainwater can be effectively avoided.

Specifically, the external cable of float switch 106 is waterproof cable, and the delay device sets up the installing support at self priming pump 108, and establishes waterproof casing at the delay device overcoat, and float switch 106 passes through waterproof cable with the delay device and is connected.

Further, the time set by the time relay 114 is 5min, and the float switch 106 adopts a safe voltage of 24V. Therefore, the safety and the reliability of the device are further guaranteed.

Further, as shown in fig. 1, the upper float 1062 of the float switch 106 is positioned higher than the water reservoir 102 is connected to the plant floor sewer 104, and the lower float 1064 of the float switch 106 is positioned lower than the water reservoir 102 is connected to the plant floor sewer 104. Therefore, when the liquid level is lower than the position of the lower float 1064 and the self-priming pump 108 stops running, the liquid level is lower than the connecting position of the reservoir 102 and the plant sewer 104, and the phenomena of reverse flow and the like cannot occur. The liquid level is higher than the float 1062 position, and under the condition of self priming pump 108 start-up operation, the liquid level can be higher than cistern 102 and factory sewer 104 hookup location, has ensured that there is more ponding when self priming pump 108 starts up operation, has avoided frequent opening of self priming pump 108 to a certain extent to stop. The specific circuit control schematic diagram is shown in fig. 2, when the liquid level is higher than the float 1062, the intermediate relay KA in the float switch 106 is switched on, thereby starting the time relay 114KT, when reaching the set time of the time relay 114 for 5min, the normally closed contact of the time relay 114KT is disconnected, and the normally open contact is closed, at this moment, the contactor KM in the control circuit of the self-priming pump 108 is started, thereby starting the self-priming pump 108, and FR is a thermal relay, when the self-priming pump 108 is overheated, the disconnection can be performed, and the self-priming pump 108 is controlled to stop running. And when the liquid level was less than lower float 1064, the auxiliary relay KA disconnection in float switch 106, then, time relay 114 KT's normally closed contact closed, and the normally open contact disconnection, contactor KM disconnection among the self priming pump 108's the control circuit, self priming pump 108 stall.

The working process of the automatic factory rainwater collecting and discharging device provided by the utility model is as follows:

the accumulated water is collected into the water reservoir 102 through the factory sewer 104, when the liquid level in the water reservoir 102 rises to cover the floater 1062 in the floater switch 106, the circuit is connected, the time relay 114 is started, and when the set time of the time relay 114 is reached for 5min, the self-priming pump 108 is started to drain water; when the liquid level in the reservoir 102 drops below the lower float 1064 in the float switch 106, the line is broken and the self-primer pump 108 stops, and so on.
