The purpose of this utility model is realized by following scheme：
A kind of ground electricity box with heat insulation function, including case lid and base, it is characterised in that：The side of the case lid passes through
Attachment means are turnover to be arranged on base；In case lid bottom covered with heat-insulation layer, and heat-insulation layer shape and base it is interior
Footpath is adapted；Opening device is provided with case lid surface.
Further, the attachment means are detachable structure, including stainless steel bearing pin and stop screw, stainless steel bearing pin
One end is inserted in the blind hole of base, and the other end is stretched into case lid, is determined on case lid provided with corresponding with stainless steel bearing pin
Position hole, stop screw is arranged on stainless steel bearing pin by positioning hole.
For more preferable heat insulation effect, prevent heat-insulation layer from coming off, be provided with groove in the bottom of case lid, guarantor is filled with groove
Warm layer.Protective layer is provided with insulation layer surface.Protective layer is fixed on case lid by setscrew.Protective layer is by aluminium-plastic panel system
Into.
Described opening device includes pull bar and draw ring.Provided with groove is installed on case lid, pull bar and draw ring are arranged on peace
Fill in groove.Case lid is, without through-hole structure, to prevent the phenomenons such as ventilation, leak, heat transfer to occur.
The heat-insulation layer is made up of the insulation pearl cotton of high resilience, and heat-insulation layer with base inner diameter is seamless closely matches somebody with somebody
Close.
For Double-cover ground electricity box, using the ramp structure cooperated between the case lid of two neighboring ground electricity box.
In the utility model, case lid and base shelve the inclined-plane that contact surface is β=30 °~70 °, make its cooperation seamless
Gap, the unlatching of case lid is also very light with closing.Shelve herein and flexible rubber cushion is installed on contact surface, to improve waterproof, shockproof etc.
Performance.According to the characteristic of material, this insulation ground electricity box make its base and case using the preferable different materials of thermal and insulating performance
Lid, its base makes of foaming self-insulating concrete, and case lid makes of fiber reinforced resinous material.
The utility model is detachable, and case lid changes convenient, and insulation and favorable sealing property, security performance are strong, sexual valence
Than high, water meter and underground installation can be prevented to be damaged by frost, alleviate meter reading and the labor intensity of attendant, effectively improve work effect
Rate, there is good promotion prospect.
