The upper end of the photovoltaic panel 206 is hinged to the outer wall of the box structure 2, and can be horizontally unfolded to increase the illumination area, or closed and embedded in the side wall of the box structure 2 to reduce wind resistance.

[0032] The U-shaped outer structure of the box structure 2 is a double-layer structure, and the top also adopts an insulating top cover 205 to form a double-layer structure. The remaining two ends also adopt the same double-layer structure of inner and outer walls plus a frame, so that the entire box structure 2 is double-layered, which improves the insulation effect of the duty room.

[0033] The traction bracket 1 can be towed by a motor vehicle to a designated location, thereby improving the mobility of the box structure 2, so that the box structure 2 can be used as a duty room beside a highway, or in some forest areas, such as a forest protection room in Daxing'anling.

[0034] The traction bracket 1 has a traction end 102 at one end, a running wheel 101 at the lower end, and leg connection sleeves 105 at four corners. The leg connection sleeves 105 have threaded support legs 104 that can rest on the ground. The box structure 2 has a staircase structure 103 on one side of the door structure 201.

[0035] A control box 16 and a battery 17 are provided in the protective cover at the bottom of the traction bracket 1, and the control box 16 and the battery 17 are electrically connected to the photovoltaic panel 206. The battery 17 can store electrical energy, which can be used as a power supply for life, and can also be used to heat the liquid in the first solar collector 5 or the second solar collector 14.

[0036] In the preferred embodiment, the skeleton structure 3 includes a plurality of U-shaped frames 301 arranged in parallel and spaced apart, a spacing area is provided between the U-shaped frames 301, a plurality of horizontal connecting rods 302 are connected between adjacent U-shaped frames 301 in the spacing area, and a plurality of inner box plates 204 are installed on the inner side of the skeleton structure 3.

[0037] The frame structure 3 is integrated with embedded window frames 304 and door frames 305, and the installation positions of doors and windows are reserved; after the outer box plate 203 is welded into a square cylindrical structure, the frame structure 3 is welded into a U-shaped structure, and hoisted and inserted horizontally into the square cylindrical structure; the inner box plate 204 is a rectangular block structure, which is assembled in each spacing area inside the U-shaped structure of the frame structure 3; the frames at both ends are fixed to the outer box plate 203 at the end and welded together, and then welded to the two ends of the square cylindrical structure; finally, the inner box plate 204 at the end is spliced ​​and installed on the inside.

[0038] In a preferred solution, a thermal insulation pad 4 is provided in the interlayer space of the vertical side wall of the box structure 2, and the thermal insulation pad 4 divides the interlayer space into inner and outer sides, and the outer side of the interlayer space is filled with thermal insulation material.

[0039] The insulation pad 4 is in contact with the side wall of the interlayer space and seals the seam. In addition to the side wall of the U-shaped frame 301, the bottom is also welded with a blocking strip. The insulation material is filled in from the top. The insulation pad 4 does not need to be set at the bottom of the box structure 2, and the insulation material can be directly filled from the inside.

[0040] In the preferred solution, the insulating top cover 205 is made of transparent material, a first solar collector 5 is arranged in the insulating top cover 205 at the upper end of the box structure 2, a plurality of parallel and spaced guide protection grooves 303 are arranged on the inner side of the interlayer space, and the guide protection grooves 303 are used to install heat pipes 6, both ends of the heat pipes 6 are connected to the first solar collector 5 to form a circulation loop, and heat transfer fluid is provided in the first solar collector 5 and the heat pipes 6.

[0041] The heat pipes 6 are arranged in a folded line along each protection groove 303 .

[0042] The heat transfer fluid can be water. The first solar collector 5 receives light, the vacuum collector tube heats the heat transfer fluid, and allows the hot water to flow into the water tank. The water tank supplies the hot water to the heat transfer tube 6 arranged in a folded shape on the inner side of the interlayer space to provide heating to the box structure 2, and the cold water flows back to the water tank for further heating.

[0043] In a preferred solution, a plurality of sound insulation pads 7 are provided on one side of the inner box plate 204 close to the outer box plate 203 , and a spacing groove body for avoiding the guide protection groove 303 is provided between each sound insulation pad 7 .

[0044] The inside of the sound insulation pad 7 is a porous loose structure, so it has both sound insulation and heat preservation effects. The side of the sound insulation pad 7 on the vertical side wall of the box structure 2 abuts against the inner side of the heat preservation pad 4, and the side of the sound insulation pad 7 at the bottom abuts against the upper end surface of the heat preservation material.

[0045] In the preferred scheme, the guide protection groove 303 is a U-shaped structure, and the inner box plate 204 is provided with a plurality of strip through grooves. The open end of the U-shaped structure of the guide protection groove 303 faces the strip through groove, and a buckle strip structure 207 is provided at the strip through groove. A clamping sleeve 208 is provided on the side of the buckle strip structure 207, and an arc sleeve 209 is provided at the bottom end of the U-shaped structure of the guide protection groove 303. The clamping sleeve 208 and the arc sleeve 209 embrace the heat pipe 6, and solid-liquid phase change material is provided in the clamping sleeve 208 and the arc sleeve 209.

[0046] The buckle strip structure 207 is detachable, so as to maintain the heat pipe 6, the clamping sleeve 208 and the arc sleeve 209 in the interlayer space.

[0047] Solid-liquid phase change materials can be hydrated salts, paraffin, etc., which are low-cost, non-toxic and harmless. The critical point of solid-liquid phase change is set at a comfortable temperature for the human body between ten and twenty-five degrees Celsius. After being heated into a liquid state, the ferrule 208 and the arc sleeve 209 are poured in from the end, and then the two ends are sealed. After waiting for cooling, the ferrule 208 can be bonded to the side of the buckle strip structure 207, and the arc sleeve 209 can be bonded to the guide protection groove 303.

[0048] The high-temperature thermal fluid has a high temperature initially. When it conducts heat to the phase change material, the phase change material changes phase. The temperature remains constant during this process to prevent the room temperature from suddenly becoming too high. Thereafter, as the heat dissipates to the outside, the temperature of the thermal fluid decreases after circulation. At this time, the heat stored in the phase change material assists in heating the room, prolonging the heating time, improving the insulation effect, and keeping the indoor temperature stable for a long time.

[0049] In the preferred scheme, a cooling water tower 8 and a connected warm water tank 12 are also provided in the heat-insulating top cover 205 at the upper end of the box structure 2. The liquid outlet pipe of the first solar collector 5 is provided with a heat exchange part 13 in the warm water tank 12. The liquid outlet pipe of the first solar collector 5 is connected with the heat conduction pipe 6. A circulating pump 10 is also provided. Each heat conduction pipe 6 is connected with the first solar collector 5 through the circulating pump 10.

[0050] The cooling tower 8 can add an appropriate amount of water to the warm water tank 12 through the water valve. The high-temperature heat transfer fluid is cooled by the warm water tank 12 and then enters the heat pipe 6. The heat stored in the first solar collector 5 is transferred to the warm water tank 12. The total amount of heat storage remains unchanged, but the temperature of the heat transfer fluid entering the heat pipe 6 can be guaranteed to be in a medium temperature state, reducing the temperature of the outer thermal insulation material to avoid excessive temperature difference, which causes the heat to diffuse rapidly to the outside, that is, by reducing the heating temperature, a longer and more continuous heating time is obtained. The medium temperature is closer to the critical temperature of the phase change of the solid-liquid phase change material. The solid-liquid phase change material is in a solid-liquid mixed state for a long time, making the indoor temperature constant and the on-duty personnel more comfortable.

[0051] In the preferred scheme, a diversion device 9 is also provided. The liquid outlet pipe of the first solar collector 5 is divided into multiple branches after passing through the diversion device 9. Each branch is provided with a flow control valve 15. Multiple temperature zones 11 are provided in the box structure 2. The branches of each liquid outlet pipe are connected to the heat transfer pipe 6 in each temperature zone 11.

[0052] The temperature zone 11 corresponds to the interval between the U-shaped frames 301. Each interval can be set as an independent temperature control area. The flow rate of the heat transfer liquid can be controlled by the flow control valve 15, thereby controlling the total heat dissipated into the area per unit time, thereby adjusting the temperature.

[0053] In the preferred solution, a second solar collector 14 is further provided at the upper end of the box structure 2. The second solar collector 14 and the first solar collector 5 are arranged opposite to each other. The collecting pipes of the second solar collector 14 and the flow control valve 15 are arranged crosswise. The second solar collector 14 is connected to the warm water tank 12, and the warm water tank 12 is provided with a water outlet.

[0054] The cross-arrangement of the collector tubes allows them to effectively receive sunlight at all times during the day.

[0055] The first solar thermal collector 5 and the second solar thermal collector 14 are provided with electric heating devices.

[0056] The cold water tower 8, the warm water tank 12 and the second solar thermal collector 14 are provided with a water outlet valve in the box structure 2, which can provide domestic water. At the same time, after the water in the warm water tank 12 is released, the warm water tank 12 can be replenished with water through the cold water tower 8 to reduce the water temperature of the warm water tank 12. In addition to being used as domestic water, the second solar thermal collector 14 can also provide hot water to the warm water tank 12 to increase the water temperature of the warm water tank 12. Therefore, the cold water tower 8 and the second solar thermal collector 14 can be used to adjust the water temperature at the inlet of the heat pipe 6.

[0057] In a preferred embodiment, the thermal insulation material is a coal gangue-based solid waste microporous foam material.

[0058] Coal gangue is waste generated during coal mining. Recycling and reuse is beneficial to saving resources and protecting the environment. Fly ash, alkali carbide slag, desulfurized gypsum, foaming agent, calcium stearate, accelerator and polycarboxylic acid water reducer are added to it to form a foaming material. It is filled into the outer layer of the interlayer space from the reserved opening at the upper end of the box side wall, and water is added to foam it to form a porous and loose insulation material with a lower density and better insulation performance. Powder and water can be directly added to the bottom of the inner side of the box, and the inner box board is buckled during foaming.

[0059] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limiting the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
