Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive exercise.
Fig. 1 is a structural diagram of a backflow prevention drainage device for a water collecting well provided by the embodiment of the utility model.
Illustration of the drawings:
the water-saving device comprises a one-way check valve 10, a drain pipe 11, a cover plate 12, a water collecting well 13, a first water pump 14, a low water level float switch 15, a second water pump 16 and a high water level float switch 17.
Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the present embodiment provides a backflow prevention drainage device for a water collecting well, which includes a submersible pump, a drainage pipe 11, a one-way check valve 10, a high water level float switch 17, and a low water level float switch 15.
The submersible pump is positioned at the bottom of the water collecting well 13, a water outlet of the submersible pump is connected with the water discharging pipe 11, and the one-way check valve 10 is installed on the water discharging pipe 11.
Specifically, the submersible pump is electrically connected to a power source, and the direction of the allowed water flow of the one-way check valve 10 coincides with the direction of the water discharge pipe 11, as indicated by the arrow in fig. 1.
And the normally open contact of the high water level float switch 17 is electrically connected with the submersible pump, and when the water level exceeds a high limit value, the normally open contact is closed to start the submersible pump. Specifically, when the normally open contact is closed, the power supply is connected with the submersible pump to supply power to the submersible pump, and the submersible pump starts to drain water to prevent water from overflowing the water collecting well 13. It should be noted that the function of adjusting the high limit value can be realized by adjusting the height of the installation position of the high water level float switch 17.
The normally closed contact of the low water level float switch 15 is electrically connected to the submersible pump, and when the water level is lower than the low limit value, the normally closed contact is disconnected to close the submersible pump. Specifically, when the normally closed contact is disconnected, the power supply and the submersible pump are disconnected, power is not supplied, the submersible pump stops working, and the submersible pump is prevented from running under the condition of no water. It should be noted that the function of adjusting the low limit value can be realized by adjusting the height of the installation position of the low water level float switch 15.
The embodiment of the utility model provides a pair of drainage device is prevented flowing backward by sump pit controls the immersible pump respectively through high water level float switch 17 and low water level float switch 15 and starts and stop, prevents through one-way check valve 10 that water flows against the current to the problem of flowing backward has been avoided.
Further, the submersible pump comprises a first water pump 14 and a second water pump 16, and the water outlets of the first water pump 14 and the second water pump 16 are both connected with the drain pipe 11; the first water pump 14 and the second water pump 16 are in a one-use-one-standby relationship.
Specifically, the first water pump 14 is provided with a first fault switch, and the first fault switch is electrically connected with the power supply and the second water pump 16. When the first fail switch is closed, the power supply is switched from supplying power to the first water pump 14 to supplying power to the second water pump 16. Similarly, a second fault switch is arranged on the second water pump 16, and the second fault switch is electrically connected with the power supply and the first water pump 14. When the second fail switch is closed, the power supply is switched from supplying power to the second water pump 16 to supplying power to the first water pump 14. When the first fault switch and the second fault switch are closed, the drainage device gives an alarm through an alarm. Therefore, when a single water pump is damaged, the water collecting well backflow prevention drainage device can still drain accumulated water in time.
Furthermore, the anti-backflow drainage device for the water collecting well further comprises a cover plate 12, wherein the cover plate 12 is in a grid shape, and a gauze is laid on the cover plate 12. The latticed cover plate 12 may facilitate observation of the conditions of the sump 13, and the gauze may be used to prevent small animals from climbing into the sump 13.
Furthermore, the cover plate 12 is made of stainless steel, and the drain pipe 11 is a hard pipe, so that the backflow prevention and drainage device of the water collecting well is firmer.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
