Description

Technical Field

[0001] The utility model relates to the technical field of diesel generators, in particular to a diesel generator set heating device and a diesel generator set. Background Art

[0002] Improving the reliability of coal mine power supply is an effective measure to ensure the life and property safety of underground workers. The Coal Mine Safety Regulations stipulate that mines should have dual-circuit power supply. When one circuit fails and stops supplying power, the other circuit should be able to bear the entire load of the mine. However, in extremely special circumstances, it is still possible for both circuits to lose power at the same time, and there are still certain safety hazards.

[0003] For the above reasons, coal mines generally use dual-circuit power supply plus backup generator power supply. In extremely special cases, when dual-circuit power outages occur at the same time, the backup generator can be used in time to meet the power supply needs of loads such as the main ventilation fan and the main drainage circulation pump, and better protect the lives of underground workers. Therefore, the reliable operation of diesel generators is the backup guarantee for mine power supply. In some coal mines in areas with low temperatures in winter, diesel generators still have the problem of difficulty in starting in low temperature environments. Utility Model Content

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] like Figure 1 As shown, the diesel generator set heating device of the embodiment of the utility model includes a heating component 1, a pipeline 2, a circulation pump 3 and a leakage protection device 4.

[0027] The heating assembly 1 includes a heating chamber 11 and a plurality of heating tubes 12. The heating chamber 11 includes an inlet 111 and an outlet 112. The heating chamber 11 can contain antifreeze. The heating tubes 12 are located in the heating chamber 11 and can heat the antifreeze in the heating chamber 11. The pipeline 2 includes an inlet pipe 21 and an outlet pipe 22. The inlet pipe 21 is connected between the antifreeze tank 6 and the inlet 111, and the outlet pipe 22 is connected between the outlet 112 and the antifreeze tank 6. The circulating pump 3 is arranged on the pipeline 2, and the circulating pump 3 is used to drive the antifreeze to circulate between the antifreeze tank 6 and the heating chamber 11. The leakage protection device 4 is arranged on the heating assembly 1, and the leakage protection device 4 is used to shut down the heating assembly 1 when the antifreeze in the heating chamber 11 is ionized.

[0028] Specifically, the inlet 111 is arranged at the upper part of the heating chamber 11, and the outlet 112 is located at the upper part of the heating chamber 11, so that the antifreeze liquid stays in the heating chamber 11 for a longer time, and the heating tube 12 has a good heating effect on the antifreeze liquid. Two heating tubes 12 can be provided, and the rated power of each heating tube 12 can be 1 kilowatt. When the heating tube 12 is damaged and leakage occurs, the leakage protection device 4 can cut off the power supply of the heating component 1 to avoid continuous leakage causing ionization, deterioration and carbonization of the antifreeze liquid. Specifically, the model of the leakage protection device 4 can be a C-type leakage protection short circuit.

[0029] In the diesel generator set heating device of the utility model embodiment, the heating component can heat the antifreeze in the heating chamber, and the circulating pump can circulate the antifreeze between the heating chamber and the antifreeze tank, so that the antifreeze is heated more evenly and the temperature rises faster, which is convenient for the diesel generator set to start quickly in a low temperature environment. The leakage protection device can cut off the power in time when the heating pipe is damaged, so as to avoid the antifreeze from being continuously ionized and carbonized to cause a major accident.

[0030] In some embodiments, Figure 1 As shown, the diesel generator set heating device includes a temperature control device 5, which is arranged in the heating chamber 11, and the temperature control device 5 can obtain the temperature data of the antifreeze liquid in the heating chamber 11, and open and close the heating component 1 according to the temperature data. The temperature control device 5 is connected to the circulation pump 3, and the temperature control device 5 can adjust the flow of the circulation pump 3 according to the temperature data.

[0031] Specifically, the temperature range of the temperature control device 5 can be set at 20°C to 40°C. When the temperature in the heating chamber 11 is lower than 20°C, the temperature control device 5 starts the heating component 1 and the circulation pump 3; when the temperature in the heating chamber 11 is higher than 40°C, the temperature control device 5 turns off the heating component 1.

[0032] In some embodiments, Figure 1 As shown, the circulation pump 3 includes a time-delay stop device 31, which can delay the shutdown of the circulation pump 3. Specifically, the temperature range of the temperature control device 5 is set at 20°C to 40°C. When the temperature in the heating chamber 11 reaches 40°C, the time-delay stop device 31 can control the circulation pump 3 to continue running for a set time after receiving the shutdown signal from the temperature control device 5, and then shut down the circulation pump 3. Since the heating component 1 still has some heat after being shut down, the delayed stop of the circulation pump 3 can transfer the remaining heat of the heating component 1 to the antifreeze liquid, which can not only avoid the temperature in the heating chamber 11 from being too high, but also save the energy consumption of the heating component 1.

[0033] In some embodiments, Figure 1As shown, two heating tubes 12 are provided, and the two heating tubes 12 are connected in parallel. When one of the heating tubes fails to work properly, the other heating tube can still work, so as not to cause the diesel generator set to fail to start, and also provide maintenance time for maintenance personnel.

[0034] The diesel generator set according to the embodiment of the present utility model is described below.

[0035] The diesel generator set of the utility model embodiment is based on the diesel generator set heating device in the above embodiment, and includes a generator body, an antifreeze tank 6 and a heating device. Figure 1 As shown, the heating device includes: a heating component 1, a pipeline 2, a circulation pump 3 and a leakage protection device 4.

[0036] The heating assembly 1 includes a heating chamber 11 and a plurality of heating tubes 12. The heating chamber 11 includes an inlet 111 and an outlet 112. The heating chamber 11 can contain antifreeze. The heating tubes 12 are located in the heating chamber 11, and the heating tubes 12 can heat the antifreeze in the heating chamber 11. The inlet 111 is arranged at the upper part of the heating chamber 11, and the outlet 112 is located at the upper part of the heating chamber 11. In this way, the antifreeze stays in the heating chamber 11 for a longer time, and the heating tubes 12 have a good heating effect on the antifreeze. Two heating tubes 12 can be provided, and the rated power of each heating tube 12 can be 1 kilowatt.

[0037] The pipeline 2 includes a liquid inlet pipe 21 and a liquid outlet pipe 22, wherein the liquid inlet pipe 21 is connected between the antifreeze tank 6 and the inlet 111, and the liquid outlet pipe 22 is connected between the outlet 112 and the antifreeze tank 6. The circulation pump 3 is arranged on the pipeline 2, and the circulation pump 3 is used to drive the antifreeze to circulate between the antifreeze tank 6 and the heating chamber 11. The circulation pump 3 can make the antifreeze circulate between the heating chamber 11 and the antifreeze tank 6, thereby making the antifreeze heated more evenly and heating faster, so as to facilitate the rapid start of the diesel generator set in a low temperature environment.

[0038] The leakage protection device 4 is provided on the heating component 1, and is used to shut down the heating component 1 when the antifreeze in the heating chamber 11 is ionized. When the heating tube 12 is damaged and leakage occurs, the leakage protection device 4 can cut off the power supply of the heating component 1 to prevent the antifreeze from being ionized, deteriorated, and carbonized due to continuous leakage. Specifically, the model of the leakage protection device 4 can be a C-type leakage protection short circuit.

[0039] In some embodiments, Figure 1 As shown, the heating device includes a temperature control device 5, which is arranged in the heating chamber 11, and the temperature control device 5 can obtain the temperature data of the antifreeze liquid in the heating chamber 11, and start and close the heating component 1 according to the temperature data. The temperature control device 5 is connected to the circulation pump 3, and the temperature control device 5 can adjust the flow of the circulation pump 3 according to the temperature data.

[0040] Specifically, the temperature range of the temperature control device 5 can be set at 20°C to 40°C. When the temperature in the heating chamber 11 is lower than 20°C, the temperature control device 5 starts the heating component 1 and the circulation pump 3; when the temperature in the heating chamber 11 is higher than 40°C, the temperature control device 5 turns off the heating component 1.

[0041] In some embodiments, Figure 1 As shown, the circulation pump 3 comprises a time-delay stop device 31 , which can delay shutting down the circulation pump 3 .

[0042] Specifically, the temperature range of the temperature control device 5 is set at 20°C to 40°C. When the temperature in the heating chamber 11 reaches 40°C, the delayed stop device 31 can control the circulation pump 3 to continue running for a set time after receiving the shutdown signal from the temperature control device 5, and then shut down the circulation pump 3. Since the heating component 1 still has some heat after being shut down, the delayed stop of the circulation pump 3 can transfer the remaining heat of the heating component 1 to the antifreeze liquid, which can not only avoid the temperature in the heating chamber 11 from being too high, but also save the energy consumption of the heating component 1.

[0043] In some embodiments, Figure 1 As shown, two heating tubes 12 are provided, and the two heating tubes 12 are connected in parallel. When one of the heating tubes fails to work normally, the other heating tube can still work, so as not to cause the diesel generator set to fail to start.
