Specific embodiment
Be described in further detail below with reference to Fig. 1-4 pairs of the utility model.
See figures.1.and.2, a kind of Integral rain/sewage lifting pump station defroster that the utility model provides comprises cover unit 1, canister unit 2 and outside barrier 3; Described canister unit 2 is formed by GRP material adhesive by external insulation layer outer cover unit 8 and cylindrical shell 9; Described outside barrier 3 is arranged on the outside of canister unit 2, extends between frozen soil layer and the non-frozen soil layer along horizontal direction to surrounding; Described cover unit 1 comprises hand-hole aluminium alloys lid 4, hand-hole roll guard 5 and pumping plant glass fiber reinforced plastic top 6; Described hand-hole aluminium alloys lid 4 is connected with described pumping plant glass fiber reinforced plastic top 6 by the first bonded block; Described hand-hole roll guard 5 is connected with described pumping plant glass fiber reinforced plastic top 6 by the second bonded block; Be provided with heat insulating material 7 inside described hand-hole aluminium alloys lid 4, described hand-hole roll guard 5 is from hand-hole aluminium alloys lid 4 described in inner support; Described pumping plant glass fiber reinforced plastic top 6 covers on described cylindrical shell 9; Heat insulating material is provided with and this heat insulating material extends to inside described cylindrical shell 9 inside described pumping plant glass fiber reinforced plastic top 6.
Wherein, described first bonded block and described second bonded block are hinge or hinge, or other dismountable linkage.
As shown in Figure 3 and Figure 4, seal foaming chamber 10 is formed between described external insulation layer outer cover unit 8 and described cylindrical shell 9, be injected with heat insulating material 7 in described seal foaming chamber 10, described insulation layer outer cover unit 8 comprises insulation layer GRP overcoat 11, GRP ring 12 and inner support muscle 13.In other words, cylindrical shell 9 outer setting foam chamber 10, cavity top and the bottom GRP ring in described bubble chamber 10 do end socket, and outside GRP tube does thermal-insulation coat, inner by brace rod as support guaranteed strength, after in cavity, inject heat insulating material.
Wherein, outside barrier 3 is made up of specific heat insulating material.According to factor calculated values such as the pumping plant environment frozen soil layer degree of depth and conditions of environmental geology, make outside barrier 3 around pumping plant in layer, the interchange of heat around isolation pumping plant between the non-frozen soil layer in bottom and top frozen soil layer, ensures pumping plant ambient temperature.
Wherein, cover unit 1, canister unit 2 and outside barrier 3 form effective closed insulation layer, the interchange of heat of isolated pumping plant inside and outside, thus realize antifreeze effect.
Wherein, based on pumping plant surrounding environment, outside barrier is set, the non-frozen soil layer of isolating exterior and frozen soil layer.
