[0002] The energy of hydroelectric power generation, thermal power generation and wind power generation is basically generated by generators. Monitoring the temperature of generators is beneficial to maintaining the stability of power generation and predicting power generation failures.
[0003] Current generator temperature monitoring devices generally use temperature sensors to monitor the temperature near the generator set and transmit the temperature to an external display in real time, thereby helping the staff to know the temperature of the generator set. However, this method requires the temperature sensor and display to work non-stop to ensure that the over-temperature of the generator set will not be missed. In actual situations, the temperature of the generator set is kept within a very safe range most of the time. Therefore, the temperature sensor and display are always working, which wastes energy, increases the aging speed, and reduces the service life. Utility Model Content
[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a temperature monitoring device for a generator set, so as to solve the technical problems mentioned in the above background technology.

[0007] Furthermore, the control unit includes a first conductive sheet fixedly connected to the bottom of the extension column, the first conductive sheet is connected to a power supply via a line, the power supply is connected to a display via a line, the power supply and the display are both located outside the shell, a second conductive sheet is fixedly connected to the inner bottom wall of the shell, the second conductive sheet is located directly below the first conductive sheet, the second conductive sheet is electrically connected to the temperature sensor, and the display is electrically connected to the second conductive sheet via a line.
[0008] Furthermore, a lower limit plate is fixedly connected to the inner wall of the housing below the piston, and when the bottom surface of the piston fits with the lower limit plate, the first conductive sheet fits with the second conductive sheet.
[0009] Furthermore, a plurality of heat-conducting rods are fixedly provided on the side wall of the shell above the piston, and the plurality of heat-conducting rods are in contact with the expansion gas.
[0010] Furthermore, a plurality of threaded sleeves are fixedly connected to the bottom of the adjustment ring, a screw is threadedly connected to the inner thread of the threaded sleeve, the screw rotates through the inner bottom wall of the shell, a gear is fixedly provided on the outer circumference of the screw located below the shell, a swivel is rotatably connected to the bottom of the shell, the temperature sensor part is located in the swivel, a gear ring is fixedly provided on the outer circumference of the swivel, and the gear ring is meshed with the plurality of gears.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:
[0013] 1. A temperature monitoring device for a generator set. When the temperature of the generator set is normal, the power supply does not supply power to the display and the temperature sensor, thereby reducing energy waste and increasing the service life of the temperature sensor and the display. When the temperature of the generator set rises to a dangerous level, the expanding gas expands due to the heat, pushing the first conductive sheet downward to contact the second conductive sheet, thereby energizing the temperature sensor and the display. At this time, the temperature sensor can monitor the temperature of the generator set in real time and display the data on the display.
[0014] 2. In this generator set temperature monitoring device, since different generator sets have different heat resistance, the staff can rotate the rotating ring to drive the adjustment ring to move vertically, adjust the initial elastic force of the spring, and then adjust the temperature required when the first conductive sheet contacts the second conductive sheet. For example, when the generator set has strong heat resistance, the staff moves the adjustment ring upward, so that the temperature required to be reached when the first conductive sheet contacts the second conductive sheet is also higher. Therefore, this device can be applied to generator sets with different heat resistance, which improves the applicability of this device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0021] Example:
[0022] Reference Figures 1 to 3 The utility model discloses a temperature monitoring device for a generator set, including a shell 1 and a temperature sensor 2 fixedly connected to the bottom of the shell 1, a piston 3 is slidably connected in the shell 1, and the shell 1 is filled with expansion gas 4 above the piston 3. An adjusting ring 6 is arranged in the lower half of the shell 1, and a plurality of springs 7 are fixedly connected between the piston 3 and the adjusting ring 6. An upper limit plate 8 is fixedly connected to the inner wall of the shell 1, and the bottom surface of the upper limit plate 8 is in contact with the top surface of the piston 3. An extension column 9 is fixedly connected to the center of the bottom of the piston 3, and a control unit 10 is arranged below the extension column 9.
[0023] In this embodiment, the top of the housing 1 is fixed to the generator set or near the generator set by bolts. The expansion gas 4 is carbon dioxide. When the temperature near the housing 1 is high, the expansion gas 4 increases in temperature and expands, thereby pushing the piston 3 to move downward. The higher the temperature near the housing 1, the higher the temperature of the expansion gas 4, the greater the expansion degree, and the greater the distance the piston 3 falls.
[0024] The center of the adjusting ring 6 is open, and the extension column 9 passes through the opening in the center of the adjusting ring 6. The spring 7 is always in a compressed state, so when the temperature of the expansion gas 4 is not high, the piston 3 fits the upper limit plate 8.
[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 2As shown, the control unit 10 includes a first conductive sheet 101 fixedly connected to the bottom of the extension column 9, the first conductive sheet 101 is connected to a power supply 102 through a line, the power supply 102 is connected to a display 103 through a line, the power supply 102 and the display 103 are both located outside the shell 1, and a second conductive sheet 104 is fixedly connected to the inner bottom wall of the shell 1, the second conductive sheet 104 is located directly below the first conductive sheet 101, the second conductive sheet 104 is electrically connected to the temperature sensor 2, and the display 103 is electrically connected to the second conductive sheet 104 through a line.
[0026] In this embodiment, in the initial state, the first conductive sheet 101 is located above the second conductive sheet 104 , so the temperature sensor 2 and the display 103 do not form a closed loop with the power supply 102 , and the temperature sensor 2 and the display 103 are not powered.
[0027] For the sake of convenience, the temperature that the generator set can withstand without damage is called the safe temperature, and the temperature that may cause damage to the generator set is called the dangerous temperature.
[0028] In the safe temperature range, the expansion amount of the expansion gas 4 is low, the falling distance of the piston 3 is short, and the first conductive sheet 101 cannot contact the second conductive sheet 104 .
[0029] When the temperature rises to a dangerous temperature, the expansion gas 4 expands more, the piston 3 falls a longer distance, and the first conductive sheet 101 can contact the second conductive sheet 104. Therefore, the first conductive sheet 101, the power supply 102, the display 103, the second conductive sheet 104 and the temperature sensor 2 form a closed loop. The temperature sensor 2 and the display 103 are powered on. The temperature sensor 2 can monitor the temperature near the generator set and display the data on the display 103.
[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, a lower limit plate 11 is fixedly connected to the inner wall of the housing 1 below the piston 3 . When the bottom surface of the piston 3 fits with the lower limit plate 11 , the first conductive sheet 101 fits with the second conductive sheet 104 .
[0031] In this embodiment, when the first conductive sheet 101 and the second conductive sheet 104 are in contact with each other, the piston 3 is in contact with the lower limit plate 11. If the temperature nearby continues to rise, the downward movement of the piston 3 will be hindered by the lower limit plate 11, preventing the upper conductive sheet and the lower conductive sheet from being damaged due to excessive force.
[0032] In a further preferred embodiment of the present invention, Figure 2 As shown, a plurality of heat-conducting rods 5 are fixedly provided on the side wall of the housing 1 above the piston 3 , and the plurality of heat-conducting rods 5 are in contact with the expansion gas 4 .
[0033] In this embodiment, the heat conducting rod 5 is made of copper material. The heat conducting rod 5 can better transfer the heat near the shell 1 to the expansion gas 4, reduce the temperature difference between the expansion gas 4 and the temperature near the shell 1, and thus improve the expansion sensitivity of the expansion gas 4.
[0034] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, a plurality of threaded sleeves 12 are fixedly connected to the bottom of the adjusting ring 6, a screw 13 is connected to the inner thread of the threaded sleeve 12, the screw 13 rotates through the inner bottom wall of the shell 1, a gear 14 is fixedly sleeved on the outer circumference of the screw 13 located below the shell 1, a swivel 15 is rotatably connected to the bottom of the shell 1, a part of the temperature sensor 2 is located in the swivel 15, a gear ring 16 is fixedly sleeved on the outer circumference of the swivel 15, and the gear ring 16 is meshed with a plurality of gears 14.
[0035] In this embodiment, the rotating ring 15 drives the plurality of gears 14 to rotate, the gears 14 drive the screws 13 to rotate, and the synchronous rotation of the plurality of screws 13 drives the threaded sleeve 12 and the adjusting ring 6 to move vertically, thereby adjusting the distance between the adjusting ring 6 and the piston 3, that is, adjusting the elastic force of the spring 7, and thus adjusting the external temperature required when the upper conductive sheet contacts the lower conductive sheet.
[0036] Different generator sets have different heat resistance, that is, the range of safe temperature and dangerous temperature is different. When the heat resistance of the generator set is strong, the staff moves the adjustment ring 6 upward, and the temperature required to be reached when the first conductive sheet 101 contacts the second conductive sheet 104 is also higher. When the heat resistance of the generator set is low, the staff moves the adjustment ring 6 downward, and the temperature required to be reached when the first conductive sheet 101 contacts the second conductive sheet 104 is also lower. It is ensured that at the safe temperature of the generator set, the first conductive sheet 101 does not contact the second conductive sheet 104; when the dangerous temperature of the generator set is reached, the first conductive sheet 101 contacts the second conductive sheet 104 in time.
[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, two fixing rods 17 are fixedly connected to the bottom of the rotating ring 15, and the fixing rods 17 are arranged in an L shape.
[0038] In this embodiment, when the staff wants to rotate the swivel 15 , they hold the corresponding fixing rod 17 with both hands and rotate it, thereby driving the swivel 15 to rotate, making it convenient for the staff to rotate the swivel 15 .
[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
