The external temperature of the pump house body 1 refers to the ambient temperature, and may be, for example, an ambient temperature within a range of 10 meters radially radiated from the outer wall of the pump house body 1.
The intelligent heat-preserving pump room of the embodiment of the invention is explained in detail below.
As shown in fig. 1 to 4, the pump house main body 1 includes a base, a tank, and a top cover. The pump room main body 1 is constructed by a double-layer plate structure to form a box body. The double-layer plate structure includes: a first wall 101 and a second wall 102. The first wall 101 and the second wall 102 are arranged in parallel at intervals, as shown in fig. 2, the first heat insulation layer 13 is arranged between the first wall 101 and the second wall 102, so that the heat conductivity of the pump room can be effectively reduced, the heat insulation performance of the whole pump room is improved, and the good heat insulation function of the pump room is realized. In some embodiments, the first thermal insulation layer 13 may be rock wool, glass wool, or polyethylene thermal insulation wool, which is not particularly limited herein.
Further, as shown in fig. 1 and 2, the electric trace heating apparatus 7 of the embodiment of the present invention includes an electric trace belt 701 and a junction box 702. The electric tracing band 701 is wound around at least a part of the outer surface of the water conveying pipeline 2, and the junction box 702 is provided in the pump room main body 1 to be electrically connected with other elements. When the temperature is low and the controller 3 controls the electric tracing band 7 to be opened, the electric tracing band 701 is heated, the water conveying pipeline 2 is heated, and water in the water conveying pipeline 2 is further prevented from being frozen. Wherein the electric tracing band 701 may be a resistance wire.
Further, the intelligent heat-preserving pump room of the embodiment of the invention further comprises: and the second heat insulation layer 14 is wrapped on at least part of the outer surface of the water conveying pipeline 2 and the electric tracing band 701 of the electric tracing device 7 so as to improve the heat insulation function of the water conveying pipeline 2. Referring to fig. 1, a water conveying pipeline 2 is used for conveying liquid, such as tap water. The water pipe 2 comprises a water inlet pipe 201 and a water outlet pipe 202, wherein the water inlet pipe 201 is communicated with a water source and is generally connected to a pump room from an underground pipeline. The underground pipeline is generally positioned below a frozen soil layer, and the part of the water conveying pipeline 2, which is connected into the pump house, extends upwards from the frozen soil layer to the interface of the pump house main body above the ground.
The pipeline part below the frozen soil layer has good heat insulation performance due to the heat insulation effect of soil, water in the pipeline part is not easy to freeze in winter with low temperature, the heat insulation performance of the pipeline part above the frozen soil layer is reduced, and the water in the pipeline part is easy to freeze in winter with low temperature, so that the water delivery function of the whole water delivery pipeline 2 is affected. In the embodiment of the present invention, the second insulating layer 14 is wrapped on the part of the water pipeline 2 above the frozen soil layer, specifically, the water inlet pipe 201 and the water outlet pipe 202 from the part of the water pipeline 2 above the frozen soil layer to the pump house main body 1, so as to increase the insulating function of the part of the pipeline, effectively avoid the pipeline from freezing, save insulating materials, and reduce the cost. Therefore, the embodiment of the invention adopts the double arrangement of the second insulating layer 14 and the electric tracing device 7, so that the icing of the water conveying pipeline 2 at low temperature can be effectively avoided.
The material of the second insulating layer 14 in the above embodiments may be rock wool, rubber-plastic sponge, or foam plastic, and the second insulating layer 14 may also be the same as the material of the first insulating layer 13, and is not limited herein.
Further, the intelligent heat-preserving pump room of the embodiment of the invention further comprises: the unit 15 of intaking installs in pump house main part 1, and the unit 15 of intaking includes two at least water pumps 151, unit import house steward and unit export house steward, and unit import house steward and inlet connection of inlet tube 201 and water pump 151 to carry the water of inlet tube 201 to the water pump 151 in, unit export house steward is connected with outlet pipe 202 with the export of water pump 151, in order to carry water to outlet pipe 202.
The water inlet set 15 is electrically connected with the controller 3 to control the operation of the water inlet set 15. Specifically, the controller 3 controls the water inlet unit 15 to be opened and closed, so as to realize the automatic operation of the pump room.
Under the state of the unit 15 operation of intaking, because water is mobile to the surface cover of conduit 2 is equipped with second heat preservation cotton 14, consequently when low temperature, difficult freezing in the conduit 2, then need not open electric heat tracing device 7, and under the non-operation state of the unit 15 of intaking, easy freezing in the conduit 2, then controller 3 need judge whether need open electric heat tracing device 7 according to the temperature of first temperature sensor 4 and the sensing of second temperature sensor 5 this moment. Therefore, under the unit running state, no matter how the external temperature of the pump room main body 1 and the temperature of the water conveying pipeline 2 are, the electric heat tracing device 7 does not need to be started, so that the problem that the pipeline temperature is too high and potential safety hazards exist due to the fact that the electric heat tracing device 7 is started for a long time at zero flow at night can be avoided, and energy consumption is saved.
Further, the intelligent heat-preserving pump room of the embodiment of the invention can further comprise: and the third temperature sensor 6 is arranged in the pump room main body 1 to sense the internal temperature of the pump room main body 1 and is electrically connected with the controller 3, so that the third temperature sensor 6 can send the temperature sensed in the pump room main body 1 to the controller 3.

According to another aspect of the invention, an intelligent heat preservation control method for a pump room is also provided, and the pump room is the intelligent heat preservation pump room in the above embodiment. Specifically, the pump house includes: the device comprises a pump room main body 1, a water conveying pipeline 2, a first temperature sensor 4, a second temperature sensor 5 and an electric tracing device 7; the water conveying pipeline 2 penetrates through the pump room main body 1, fluid is conveyed to the pump room, the first temperature sensor 4 is arranged outside the pump room main body 1 to sense the temperature outside the pump room main body 1, the second temperature sensor 5 is arranged on the water conveying pipeline 2 to sense the temperature of the water conveying pipeline 2 and is electrically connected with the controller 3, and the electric heat tracing device 7 is arranged on the outer surface of at least part of the water conveying pipeline 2.
As shown in fig. 7, the intelligent heat preservation control method includes:
s200: acquiring the external temperature of the pump room main body 1 sensed by the first temperature sensor 4;
s400: when the external temperature of the pump room main body 1 is lower than a first preset temperature, acquiring the temperature of the water conveying pipeline 2 sensed by the second temperature sensor 5;
s600: and when the temperature of the water conveying pipeline 2 is lower than the second preset temperature, the electric tracing device 7 is started to heat the water conveying pipeline 2.
When the first preset temperature of the pump room main body 1 may be-3 ℃, -4 ℃, -5 ℃, -7 ℃, -8 ℃ or-10 ℃, the external environment temperature is low, the water conveying pipeline 2 is easily frozen, and the temperature of the water conveying pipeline 2 sensed by the second temperature sensor 5 needs to be further obtained. The second preset temperature may be 38 ℃, 39 ℃ or 40 ℃, in an embodiment, the second preset temperature is 40 ℃, when the temperature of the water conveying pipeline 2 is less than 40 ℃, the electric tracing device 7 may be turned on, and of course, the second preset temperature may be set to other values as described above, and a person skilled in the art may select the second preset temperature according to actual situations, and the second preset temperature is not limited herein. The second preset temperature is set to 38-40 ℃, which is mainly to prevent the electric heat tracing device 7 from heating the water conveying pipeline 2, so that the liquid conveyed in the water conveying pipeline 2 is further heated, and the normal use of residents is affected by overhigh temperature, therefore, although the outdoor temperature is very low, the electric heat tracing device 7 cannot be started if the water temperature in the water conveying pipeline 2 exceeds 38-40 ℃. Therefore, the method of the embodiment of the invention can not only prevent the water in the water transmission pipeline 2 from freezing, but also prevent the water in the water transmission pipeline 2 from being heated and heated too high, and simultaneously, the energy is saved.

Therefore, the starting times and time of the electric tracing device can be reduced, and the energy consumption is saved.
Further, the method further comprises: acquiring the external temperature of the pump room main body 1 sensed by the first temperature sensor 4; and when the external temperature of the pump room main body 1 is higher than the third preset temperature, the electric tracing device 7 is turned off.

In the above embodiment, when the first preset temperature is-3 ℃, -4 ℃, -5 ℃, -7 ℃, -8 ℃ or-10 ℃, the third preset temperature may be 0 ℃ to-1 ℃, -1 ℃ to-2 ℃, -3 ℃ to-4 ℃, -5 ℃ to-4 ℃, -6 ℃ to-5 ℃ or-8 ℃ to-7 ℃, and the electric heat tracing apparatus 7 is turned off. The first preset temperature and the third preset temperature are set differently, mainly considering the signal fluctuation of the first temperature sensor 4, that is, the first temperature sensor 4 may not sense the small temperature difference of the external temperature accurately due to the signal fluctuation, and preventing the electric tracing device 7 from being frequently turned on.
Further, the method further comprises: acquiring the temperature of the water conveying pipeline 2 sensed by the second temperature sensor 5; and when the temperature of the water conveying pipeline 2 is higher than the second preset temperature, the electric tracing device 7 is closed. It is indicated that the temperature of the water in the water conveying pipeline 2 is already slightly high, and if the water is further heated, the normal use is affected by the overhigh temperature, and meanwhile, the energy consumption can be further saved.
