Description
Technical Field
The utility model relates to the field of buildings, in particular to a water supply and drainage technology, and specifically relates to an anti-freezing prefabricated pump station.
Background
At present, the prefabricated pump station for blowdown, its inside temperature changes along with ambient temperature changes, and in the northern area in winter, because ambient temperature is lower, the inside sewage of pump station freezes easily, can not discharge smoothly after freezing, leads to the pump station can not normally work, and in addition, sewage freezes the back volume in the pipeline and can expand, can cause the damage of different degree to water pump and pipeline.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the heating system is added in the pump station, so that the sewage in the pump station is effectively prevented from freezing, and the pump station can work normally under the cold condition.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prefabricated pump station of type of preventing frostbite, includes the pump station cavity, sets up inlet tube and outlet pipe, setting on the pump station cavity are in inside immersible pump of pump station cavity and setting are in switch board outside the pump station cavity, the switch board pass through electric circuit with the immersible pump is connected, and according to the inside sewage water level height control of pump station cavity the immersible pump opens and stops, its characterized in that, set up temperature control device in the switch board, pump station cavity inboard bottom sets up temperature sensor, the inside height that is less than the pump stopping water level of pump station cavity sets up heating device, heating device reaches temperature sensor all through electric circuit with in the switch board temperature control device is connected.
Further, prefabricated pump station of type of preventing frostbite, heating device's quantity is a plurality of, and evenly distributed in inside the pump station cavity, heating device starts the heating when sewage temperature less than or equal to zero degree centigrade, stops heating when sewage temperature more than or equal to ten degrees centigrade.
Further, prefabricated pump station of type of preventing frostbite, temperature sensor sets up the position and keeps away from heating device.
Furthermore, the heating device comprises an independent power supply, a heater and a relay, an input loop of the relay is connected with the temperature control device, and the heater and the independent power supply are connected in an output loop of the relay.
Compared with the prior art, the utility model has the advantages that the effect is positive and obvious, the temperature of the sewage in the cavity of the pump station is always controlled above the freezing point through the arranged temperature sensor, the heating device and the temperature controller, the normal work of the pump station is prevented from being influenced by the freezing of the sewage, the waste of energy is avoided, and the anti-freezing capability of the prefabricated pump station is effectively improved.

FIG. 1 is a block diagram of the present invention.
Detailed Description
Example (b):
as shown in figure 1, the anti-freezing prefabricated pump station comprises a pump station cavity 1, a water inlet pipe 2 and a water outlet pipe 4 which are arranged on the pump station cavity 1, a submersible pump 3 which is arranged in the pump station cavity 1 and a control cabinet 5 which is arranged outside the pump station cavity 1, wherein the control cabinet 5 is connected with the submersible pump 3 through an electric circuit and controls the submersible pump 3 to start and stop according to the height of the sewage level in the pump station cavity 1, the anti-freezing prefabricated pump station is characterized in that a temperature control device is arranged in the control cabinet 5, a temperature sensor 8 is arranged at the bottom of the inner side of the pump station cavity 1, a heating device 9 is arranged in the pump station cavity 1 at a height lower than the pump stop water level 7, the heating device 9 and the temperature sensor 8 are both connected with the temperature control device in the control cabinet 5 through electric circuits, and in the actual working environment, sewage enters the pump station cavity 1 from the water inlet pipe 2, when the sewage water level surpassed and opened pump water level 6, switch board 5 control immersible pump 3 starts to pass through outlet pipe 4 drainage sewage falls to under the pump water level 7, works as temperature sensor 8 records that the sewage temperature is less than the temperature range of setting for when controlling through temperature control device heating device 9 starts until the sewage temperature is higher than the temperature range of setting for, will temperature sensor 8 with heating device 9 sets up respectively pump station cavity 1 inboard bottom and the position that is less than the height of pump water level 7 can effectively avoid temperature sensor 8 with heating device 9 exposes in the air to prevent that the temperature measurement is inaccurate or heating device 9 is invalid to heat.
Further, the prefabricated pump station of type of preventing frostbite, heating device 9's quantity is a plurality of, and evenly distributed in inside pump station cavity 1, heating device 9 starts the heating when sewage temperature less than or equal to zero degree centigrade, stops the heating when sewage temperature more than or equal to ten degrees centigrade, can be based on pump station cavity 1 diameter size is in its inside different quantity heating device 9 guarantees to heat evenly and improves heating efficiency, because the ice-cube specific gravity is lighter than water, and the temperature of lower part sewage is higher than zero degree centigrade and when being in liquid state, still can have floating ice in sewage, so start and stop the settlement temperature range of heating device 9 work is for zero to ten degrees centigrade, guarantees the excessive consumption of the energy is avoided in the time of the sewage of pump station cavity 1 is not iced.
Further, prefabricated pump station of type of preventing frostbite, temperature sensor 8 sets up the position and keeps away from heating device prevents to disturb 8 measurement sewage temperatures of temperature sensor.
