Technical Field
[0001] This utility model relates to the field of generator technology, and more specifically, to a mobile internal combustion engine generator set adapted to low-temperature environments. Background Technology
[0002] An internal combustion engine generator set is a device that uses an internal combustion engine to drive a generator to generate electricity. It is an important independent power generation unit, widely used in various places, including industry, agriculture, construction sites, transportation, and emergency backup power. The bottom of the internal combustion engine generator set can be moved by installing a detachable bracket with casters.
[0003] However, in low-temperature environments, internal combustion generator sets have the following problems: fuel is prone to solidification or waxing, resulting in poor fuel flow and affecting fuel supply; the viscosity of the internal combustion engine oil increases, and the lubricating oil becomes more viscous, causing the engine to start poorly or even fail to start; due to the increased viscosity of internal engine parts and lubricating oil, the wear of the engine during operation will also increase; incomplete fuel atomization leads to incomplete combustion, reducing the overall efficiency of the generator.
[0004] Existing methods for solving the problem of internal combustion engine generator set operation in low-temperature environments generally involve sprinkling large amounts of hot or boiling water on its surface. This method is time-consuming, labor-intensive, and ineffective. Another method is to install an insulation frame around the internal combustion engine generator set, but in extreme low-temperature weather, it is difficult to ensure that the temperature inside the insulation frame remains at the normal operating temperature of the generator set. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a mobile internal combustion engine generator set that is adapted to low-temperature environments.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile internal combustion engine generator set adapted to low-temperature environments, comprising a detachable base plate, a base fixedly connected to the top of the detachable base plate, an insulation box and a generator set body fixedly connected to the top of the base, the generator set body located inside the insulation box, sealing components installed on both sides of the insulation box, a heat dissipation component installed in the middle of the top of the insulation box, a water tank assembly, a filter assembly, and a circulating water pump installed on the front of the insulation box, and heating water coils installed around the inner wall of the insulation box. A heat-conducting sheet is fixedly connected to the surface of the heating water coil. A temperature sensor is installed on the top of the inner wall of the insulation box. The water tank assembly includes a water tank body fixedly connected to the surface of the insulation box. A heating component is installed inside the water tank body. A coil connecting pipe is fixedly connected to the bottom of the water tank body. The other end of the coil connecting pipe is fixedly connected to the circulation outlet of the heating water coil. A first connecting pipe is fixedly connected to the right side of the water tank body. The insulation box includes an insulation frame. An insulation layer is fixedly connected to the outside of the insulation frame. A reflective layer is fixedly connected to the outside of the insulation layer.
[0007] As a preferred embodiment of the present invention, the filter assembly includes a filter box fixedly connected to the right side of the first connecting pipe, a second connecting pipe fixedly connected to the right side of the filter box, a filter frame fixedly connected to the right side of the inner wall of the filter box, and a filter screen fixedly connected to the inner side of the filter frame.
[0008] As a preferred embodiment of this utility model, a conical frame is fixedly connected to the bottom of the filter box, a waste discharge pipe is fixedly connected to the middle of the bottom of the conical frame, and a control valve is installed on the inner side of the waste discharge pipe.
[0009] As a preferred embodiment of this utility model, the inlet pipe of the circulating water pump is fixedly connected to the second connecting pipe, and the outlet pipe of the circulating water pump is fixedly connected to the circulating inlet of the heating water coil.
[0010] As a preferred technical solution of this utility model, the sealing component includes a support block fixedly connected to the side of the heat preservation box, a drive motor fixedly connected to the front of the support block, a lead screw fixedly connected to the output shaft of the drive motor, a moving block threaded onto the outer side of the lead screw, and a sealing plate fixedly connected to the bottom of the moving block.
[0011] As a preferred technical solution of this utility model, ventilation holes are provided on both sides of the insulated box, and a dustproof net is fixedly connected to the inner side of the ventilation hole. The ventilation hole and the sealing plate are compatible with each other.
[0012] As a preferred embodiment of this utility model, the heat dissipation assembly includes a heat dissipation frame fixedly connected to the top of the heat insulation box, a heat dissipation fan installed on the inner side of the heat dissipation frame, a support rod fixedly connected to the top of the heat dissipation frame, and a rain cover fixedly connected to the top of the support rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model includes a water tank assembly, a circulating water pump, a heating water coil, and heat-conducting plates. The heating assembly heats the water inside the water tank. The circulating water pump then pumps the heated water into the heating water coil. The heat-conducting plates transfer heat to the air inside the insulation box, thereby increasing the operating temperature of the generator set. Finally, the water inside the heating water coil flows back to the water tank through the coil connecting pipe for further heating. This prevents the generator set from failing to start normally or affecting its performance due to low temperatures. The insulation layer also provides insulation, reducing the rate at which air inside the insulation box escapes to the outside.
[0015] 2. This utility model, by incorporating a sealing component and a heat dissipation component, allows the drive motor to rotate when the temperature inside the insulation box is too high. This rotation causes the moving block to move the sealing plate to the back, thus removing the sealing plate from the ventilation holes. The heat dissipation fan is then activated to allow air circulation. Low-temperature air from the outside enters the insulation box through the ventilation holes, while the high-temperature air inside the insulation box is exhausted through the heat dissipation frame. This achieves heat exchange between the air inside the insulation box and the generator set, keeping the main body at a normal operating temperature. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1 to 7 As shown, this utility model provides a mobile internal combustion engine generator set adapted to low-temperature environments, including a detachable base plate 1. A base 2 is fixedly connected to the top of the detachable base plate 1. An insulation box 3 and a generator set body 9 are fixedly connected to the top of the base 2. The generator set body 9 is located inside the insulation box 3. Sealing components 4 are installed on both sides of the insulation box 3. A heat dissipation component 5 is installed in the middle of the top of the insulation box 3. A water tank component 6, a filter component 7, and a circulating water pump 8 are installed on the front of the insulation box 3. Heating water coils 304 are installed around the inner wall of the insulation box 3. Heat-conducting plates 3 are fixedly connected to the surface of the heating water coils 304. 05. A temperature sensor 303 is installed on the top of the inner wall of the heat preservation box 3. The water tank assembly 6 includes a water tank body 601 fixedly connected to the surface of the heat preservation box 3. A heating assembly 602 is installed on the inner side of the water tank body 601. A coil connecting pipe 604 is fixedly connected to the bottom of the water tank body 601. The other end of the coil connecting pipe 604 is fixedly connected to the circulation outlet of the heating water coil 304. A first connecting pipe 603 is fixedly connected to the right side of the water tank body 601. The heat preservation box 3 includes a heat preservation frame 31. A heat preservation layer 32 is fixedly connected to the outer side of the heat preservation frame 31. A reflective layer 33 is fixedly connected to the outer side of the heat preservation layer 32.
[0026] In this embodiment, the temperature sensor 303 can monitor the temperature inside the insulation box 3. When the temperature is lower than the set range, the heating component 602 is activated to heat the water inside the water tank body 601. The heated water is pumped into the heating water coil 304 by the circulating water pump 8. The heat conduction plate 305 improves the heat conduction of the water and transfers the heat to the air inside the insulation box 3, thereby increasing the working temperature of the generator set body 9. Finally, the water inside the heating water coil 304 flows back to the water tank body 601 through the coil connecting pipe 604 to continue heating, avoiding the generator set body 9 from failing to start normally and affecting the working performance of the generator set body 9 due to the low temperature environment. The insulation layer 32 can play a role in heat preservation and reduce the rate at which the air inside the insulation box 3 is lost to the outside.
[0027] When the temperature inside the insulation box 3 is too high, the drive motor 402 is started to drive the lead screw 403 to rotate, thereby moving the moving block 404 to move the sealing plate 405 to the back. As a result, the sealing plate 405 no longer seals the ventilation hole 301, and the cooling fan 502 is started to drive air circulation. The low-temperature air from the outside enters the interior of the insulation box 3 through the ventilation hole 301, and the high-temperature air inside the insulation box 3 is discharged through the heat dissipation frame 501, thereby realizing heat exchange of the air inside the insulation box 3 and keeping the generator set body 9 at a normal operating temperature.
[0028] The filter assembly 7 includes a filter box 701 fixedly connected to the right side of the first connecting pipe 603, a second connecting pipe 707 fixedly connected to the right side of the filter box 701, a filter frame 705 fixedly connected to the right side of the inner wall of the filter box 701, and a filter screen 706 fixedly connected to the inner side of the filter frame 705.
[0029] The filter screen 706 can intercept and filter foreign objects in the water as well as impurities generated inside the heating water coil 304, keeping the water in a relatively clean state.
[0030] The bottom of the filter box 701 is fixedly connected to a conical frame 702, and the middle of the bottom of the conical frame 702 is fixedly connected to a waste discharge pipe 703. A control valve 704 is installed on the inner side of the waste discharge pipe 703.
[0031] Foreign objects filtered by filter screen 706 accumulate on the inside of cone frame 702 under the action of gravity. The opening and closing of waste discharge pipe 703 can be controlled by control valve 704, so as to facilitate the discharge of foreign objects.
[0032] The inlet pipe of the circulating water pump 8 is fixedly connected to the second connecting pipe 707, and the outlet pipe of the circulating water pump 8 is fixedly connected to the circulating inlet of the heating water coil 304.
[0033] The circulating water pump 8 can realize the circulation of water, so that the heated water inside the water tank body 601 enters the interior of the heating water coil 304 through the circulation inlet of the heating water coil 304, and the heat of the water is transferred to the air inside the insulation box 3 through the heating water coil 304 and the heat conduction plate 305.
[0034] The enclosed component 4 includes a support block 401 fixedly connected to the side of the insulation box 3. A drive motor 402 is fixedly connected to the front of the support block 401. A lead screw 403 is fixedly connected to the output shaft of the drive motor 402. A moving block 404 is threaded onto the outer side of the lead screw 403. A sealing plate 405 is fixedly connected to the bottom of the moving block 404. Ventilation holes 301 are provided on both sides of the insulation box 3. A dustproof net 302 is fixedly connected to the inner side of the ventilation hole 301. The ventilation hole 301 and the sealing plate 405 are mutually compatible.
[0035] The sealing plate 405 can seal the ventilation hole 301, thereby greatly reducing the convection between the air inside the insulation box 3 and the low-temperature air outside. The drive motor 402 is electrically connected to the temperature sensor 303. When the internal temperature of the insulation box 3 is too high, the moving block 404 drives the sealing plate 405 to move to the back, so that the sealing plate 405 no longer seals the ventilation hole 301.
[0036] The heat dissipation component 5 includes a heat dissipation frame 501 fixedly connected to the top of the heat insulation box 3. A heat dissipation fan 502 is installed inside the heat dissipation frame 501. A support rod 503 is fixedly connected to the top of the heat dissipation frame 501. A rain cover 504 is fixedly connected to the top of the support rod 503.
[0037] The heat dissipation frame 501 is connected to the interior of the insulation box 3. When heat dissipation is required, the high-temperature air inside the insulation box 3 is discharged through the heat dissipation frame 501. The rain cover 504 can prevent rainwater from entering the interior of the insulation box 3 through the heat dissipation frame 501.
[0038] Working principle and usage process of this utility model:
[0039] Temperature sensor 303 can monitor the temperature inside the insulation box 3. When the temperature is lower than the set range, heating component 602 is activated to heat the water inside the water tank body 601. The heated water is pumped into the heating water coil 304 by circulating water pump 8. Heat conduction plate 305 improves the heat conduction of the water and transfers the heat to the air inside the insulation box 3, thereby increasing the working temperature of the generator set body 9. Finally, the water inside the heating water coil 304 flows back to the water tank body 601 through coil connecting pipe 604 to continue heating, avoiding the generator set body 9 from failing to start normally and affecting the working performance of the generator set body 9 due to low temperature environment. Insulation layer 32 can play a role in heat preservation and reduce the rate at which the air inside the insulation box 3 is lost to the outside.
[0040] When the temperature inside the insulation box 3 is too high, the drive motor 402 is started to drive the lead screw 403 to rotate, thereby moving the moving block 404 to move the sealing plate 405 to the back. As a result, the sealing plate 405 no longer seals the ventilation hole 301, and the cooling fan 502 is started to drive air circulation. The low-temperature air from the outside enters the interior of the insulation box 3 through the ventilation hole 301, and the high-temperature air inside the insulation box 3 is discharged through the heat dissipation frame 501, thereby realizing heat exchange of the air inside the insulation box 3 and keeping the generator set body 9 at a normal operating temperature.
