However, the thermistor sensor is a high-precision component. Under the continuous flow and impact of cooling water, it may fail or its performance may deteriorate, thereby affecting the measurement of the operating temperature of the generator set.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The heat dissipation method of the generator set includes both air cooling and water cooling, which depends on the type, power and operating environment of the generator set. Among them, the water cooling method reduces the temperature of the generator set through liquid circulation, which has the advantages of low noise and flexible installation. Therefore, during the cooling process, the circulation of cooling water in the cooling pipe will continuously impact the thermistor sensor 54 set in the cooling pipe for detecting water temperature, causing the sensor to vibrate to a certain extent. Frequent vibration may cause the sensor to malfunction.

[0023] Embodiment 1

[0024] In the prior art, when the temperature of the operating unit is determined by detecting the cooling water temperature, the thermistor sensor 54 used for detection is prone to failure due to water flow impact. Figure 1-Figure 5 The present embodiment proposes a generator set operating temperature detection device, which avoids the cooling water directly colliding with the thermistor sensor 54 and causing the thermistor sensor 54 to vibrate, thereby improving the protection of the thermistor sensor 54. The device mainly comprises a measuring tube 1 provided with connecting flanges at both ends of the measuring tube 1, an observation window 4 is provided on the outside of the measuring tube 1, and a detection component 5 for detecting the operating temperature of the generator set is provided in the measuring tube 1. When installing the equipment, the measuring tube 1 can be installed at the cooling water outlet through the connecting flange, and then the temperature of the outflowing cooling water is detected by the detection component 5 provided on the measuring tube 1, and the operating temperature of the generator set is determined by the cooling water temperature.

[0025] In order to reduce the impact that the thermistor sensor 54 may receive, the present embodiment blocks the flowing cooling water through the setting of the detection component 5 to prevent it from directly impacting the thermistor sensor 54. Figure 2 As shown, the detection assembly 5 includes a mounting sleeve 51 fixedly mounted on the outside of the measuring tube 1, and the inner cavity of the mounting sleeve 51 is connected to the inner cavity of the measuring tube 1, a sliding rod 53 is slidably mounted in the mounting sleeve 51, a thermistor sensor 54 is provided at the lower end of the sliding rod 53, an anti-collision frame 55 fixedly connected to the sliding rod 53 is provided around the thermistor sensor 54, and the upper cross-section of the anti-collision frame 55 is triangular, a connecting groove 56 is provided on the anti-collision frame 55, and the cross-section of the connecting groove 56 is S-shaped, a temperature gauge 52 is provided at the upper end of the mounting sleeve 51, and the thermistor sensor 54 and the temperature gauge 52 are connected. A spiral connecting wire 510 is provided between the thermistor sensor 54 and the temperature meter 52. Since the thermistor sensor 54 is electrically connected to the temperature meter 52 through the connecting wire 510, the temperature meter 52 can convert the electrical signal transmitted by the thermistor sensor 54 into a temperature index, which is convenient for the staff to observe intuitively. At the same time, the anti-collision frame 55 set on the outside of the thermistor sensor 54 will shield the thermistor sensor 54, and because its cross-section is triangular, it can divert the flowing cooling water to prevent it from colliding with the thermistor sensor 54 and causing the thermistor sensor 54 to vibrate. In addition, Figure 2 As shown, the inner side of the anti-collision frame 55 is connected to the inner cavity of the measuring tube 1, so the cooling water in the measuring tube 1 can cover the thermistor sensor 54, so that the thermometer 52 can accurately display the water temperature. However, this will cause the cooling water at the thermistor sensor 54 to flow slowly, and the outflowing cooling water temperature cannot be monitored in real time. In this embodiment, a connecting groove 56 is provided on the anti-collision frame 55, so that the cooling water can flow into the inner side of the anti-collision frame 55 during the flow process, thereby accelerating the flow rate of the cooling water around the thermistor sensor 54, so that the thermistor sensor 54 can monitor the water temperature in real time. At the same time, the S-shaped cross-section of the connecting groove 56 consumes the energy of the cooling water movement and prevents it from directly hitting the thermistor sensor 54, thereby reducing the shaking that may occur to the thermistor sensor 54 and improving the protection of the thermistor sensor 54.

[0026] An enlarged cavity 57 is provided at the connection point between the connecting groove 56 and the inner cavity of the anti-collision frame 55, and the cross-section of the enlarged cavity 57 is conical, and its internal dimensions increase from right to left. Since the internal dimensions of the enlarged cavity 57 increase from right to left, the cooling water flowing out of the connecting groove 56 will be dispersed outward due to the enlargement of the space, further reducing its kinetic energy of flow and reducing the force of its impact on the thermistor sensor 54.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, the technical solution proposed in the first embodiment is used to solve the disadvantage of the prior art that when the temperature of the operating unit is determined by detecting the cooling water temperature, the thermistor sensor 54 used for detection is prone to malfunction due to water flow impact. However, in order to control the flow, reduce pressure loss or adapt to different heat dissipation requirements. In these cases, there may be a certain amount of air or other gas in the pipeline, so sometimes the cooling water cannot completely fill the cooling pipe. For the thermistor sensor 54 for detecting the water temperature, being located in the water may be a more appropriate choice. This is because the position in the water can provide more comprehensive temperature information while reducing the impact of impurities and flow on the measurement.

[0029] Reference Figure 1-Figure 5 The mounting sleeve 51 is provided with an adjusting assembly 59 for adjusting the height of the thermistor sensor 54. The adjusting assembly 59 includes an adjusting gear 591 rotatably mounted on one side of the sliding rod 53. The two sides of the adjusting gear 591 are respectively meshed with a fixed rack 592 fixedly connected to the mounting sleeve 51 and a movable rack 594 slidably connected to the mounting sleeve 51, and the teeth on the movable rack 594 and the fixed rack 592 correspond to each other. A plurality of telescopic springs 593 fixedly connected to the mounting sleeve 51 are provided on one side of the movable rack 594. A driving rod 595 is fixedly mounted on one side of the movable rack 594, and the driving rod 595 slides through the mounting sleeve 51 with one end and is installed with a knob. In this embodiment, by adjusting The setting of component 59 can adjust the height of the thermistor sensor 54. The staff can observe the specific water surface height in the measuring tube 1 through the observation window 4 and make adjustments based on this. During the adjustment process, the driving rod 595 is first pulled outward to make the movable rack 594 disengage from the adjusting gear 591. At this time, the sliding rod 53 can be controlled to slide freely to adjust the position of the thermistor sensor 54. After the adjustment is completed, the driving rod 595 is released. Under the action of the telescopic spring 593, the movable rack 594 re-engages with the adjusting gear 591, thereby limiting the rotation of the adjusting gear 591 through the fixed rack 592, thereby achieving the effect of fixing the position of the thermistor sensor 54.

[0030] A water diverting protrusion 58 is fixedly installed on one side of the sliding rod 53, and the cross-section of the water diverting protrusion 58 is triangular. The water diverting protrusion 58 with a triangular cross-section can divert the flowing cooling water, reduce the impact force of the cooling water hitting the sliding rod 53, and ensure the stability of the thermistor sensor 54.

[0031] A sealing groove 2 is provided on the connecting flange, and the cross-section of the sealing groove 2 is conical, and its internal dimensions increase from the inside to the outside. A sealing ring 3 is provided in the sealing groove 2. When connected to the cooling pipe, the connecting flange on the cooling pipe will squeeze the sealing ring 3 and move it to the inside of the sealing groove 2. Since the internal dimensions of the sealing groove 2 increase from the inside to the outside, as the sealing ring 3 moves, the contact area between it and the sealing groove 2 becomes larger and larger, thereby reducing the assembly gap between the cooling pipe and the measuring tube 1 and achieving a sealing effect.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
