[0002] The oil cooler is a turbine oil cooling device in a steam turbine, and if the oil temperature is too high, the equipment in the device such as bearings may be softened, deformed or burned. Conventionally, industrial cooling circulating water is used as a medium to exchange heat between the heat of the lubricating oil in the steam turbine device and the cold water to reduce the oil temperature of the lubricating oil in the device or control the oil temperature within a certain range, so that the oil temperature in the device can be controlled to ensure normal operation of the unit.

The water temperature of the inlet and outlet water pipes of the cooling water is monitored to determine the cooling efficiency of the oil cooler, and the oil temperature is monitored to determine the quality of the oil in the oil cooler. If the oil temperature in the oil cooler is too high, the oil will deteriorate, the viscosity of the deteriorated oil will increase, the flowability will be poor, and the oil will adhere to the surface of the temperature detector, which will affect the real detection value of the oil temperature. Similarly, the detector for detecting the cooling water temperature will be affected by the real detection value of the water temperature due to the attachment of impurities on the surface of the temperature detector caused by the change of water quality during long-term use.

[0018] The oil cooler is a turbine oil cooling device in a steam turbine. If the oil temperature is too high, the equipment in the device, such as bearings, may soften, deform or burn. Conventionally, industrial cooling circulating water is used as a medium to exchange heat between the heat of the lubricating oil in the steam turbine device and the cold water, so as to reduce the oil temperature of the lubricating oil in the device or control the oil temperature within a certain range. Therefore, the oil temperature in the device can be controlled to ensure normal operation of the unit. The commonly used oil cooler includes inlet and outlet water pipes, inlet and outlet oil pipes, a drain pipe and an oil drain pipe. The water temperature of the inlet and outlet water pipes is monitored to determine the cooling efficiency of the oil cooler, and the oil temperature is monitored to determine the quality of the oil in the oil cooler. If the oil temperature in the oil cooler is too high, the oil will deteriorate, the viscosity of the deteriorated oil will increase, the flowability will be poor, and the oil will adhere to the surface of the temperature detector, which will affect the real detection value of the oil temperature. Similarly, the water quality changes after long-term use of the detector for detecting the cooling water temperature, and the impurities adhered to the surface of the temperature detector will affect the real detection value of the water temperature. Therefore, the utility model provides an oil cooler temperature detection device to optimize the temperature detection device of the inlet and outlet water pipes and the inlet and outlet oil pipes of the oil cooler. The surface of the temperature detector is cleaned without removing the temperature detector, the surface impurities affecting the detection value are removed, and the temperature detection performance of the oil cooler is improved.

[0019] The utility model will be explained in detail below with reference to the drawings.

[0020] The utility model provides a kind of oil cooler temperature detection device, comprising: mounting head 1, the connector 2 of the bottom surface solid connection of mounting head 1, the temperature detector 3 of the bottom surface connection of the connector 2, the center of mounting head 1 is provided with bolt 4, the head of bolt 4 is hexagon nut and protrudes from the top surface of mounting head 1;Bolt 4 is connected with connector 2 by sealing structure 5 after passing through connector 2, the bottom end of bolt 4 is equipped with multiple wave-shaped brushes 6, and the partial outside bristle of brush 6 is attached to the surface of temperature detector 3.

[0021] Wherein, the aforementioned connector 2 is hollow cylindrical structure, and hollow column outer wall is equipped with thread and is used to be connected with inlet and outlet water pipe or inlet and outlet oil pipe.Surrounding the outer wall of the connector 2 and the bottom surface of the mounting head 1, the main sealing ring 7 is connected.The main sealing ring 7 includes two layers of organ type sealing ring.In addition, the aforementioned sealing structure 5 is aluminum sealing ring, and the circumferential side of the sealing ring is provided with concave sealing groove 51, which is connected with the spherical sealing ring on the connector 2.Adjacent the curved portion of wave-shaped brush 6 is complementary.

[0022] As Figure 1As shown, the outer wall of the connector 2 is screwed with the water inlet and outlet pipe or the oil inlet and outlet pipe, and is screwed to the bottom surface of the main sealing ring 7 after compression, and is in abutment with the water inlet and outlet pipe or the oil inlet and outlet pipe, at which time the temperature detector 3 is deeply inserted into the water inlet and outlet pipe or the oil inlet and outlet pipe to detect the temperature. When it is necessary to remove the impurities on the surface of the temperature detector 3, the operator holds the hexagonal nut protruding on the mounting head 1, rotates the latch 4, and rotates the bristles on the brush 6 at the bottom end of the latch 4 around the temperature detector 3, so that the bristles remove the impurities on the surface of the temperature detector 3, and the impurities are carried away by the fluid flow. After the impurities on the surface of the temperature detector 3 are removed, they will no longer affect the temperature sensor to detect the water temperature or the oil temperature.

[0023] The latch 4 is threadedly connected with the inner wall of the connector 2 and the inner wall of the mounting head 1, but the structure of the thread is specially set so that the latch 4 does not move downward or upward relative to the mounting head 1 when it is rotated. In addition, the seal structure 5 at the lower part of the latch 4 is set so that the latch 4 can not only be rotated, but also be sealed with the connector 2 to avoid water or oil in the water inlet and outlet pipe or the oil inlet and outlet pipe from leaking from the latch 4. The main sealing ring 7 is provided with two or more layers of organ structure, so that it has a certain compression amount, which is helpful to the compatibility of different tightening degrees of the latch 4. When the latch 4 needs to be deeply inserted into the pipe, the connector 2 is further screwed downward, that is, the distance between the bottom surface of the mounting head 1 and the outer surface of the pipe wall is reduced, at which time the main sealing ring 7 is compressed. Similarly, when the latch 4 needs to be shallowly inserted into the pipe, the connector 2 is appropriately released in the opposite direction, that is, the distance between the bottom surface of the mounting head 1 and the outer surface of the pipe wall is increased, at which time the main sealing ring 7 restores the original compression amount.

[0024] In some embodiments, a clamping or other structure can be provided between the temperature monitor and the bottom surface of the latch 4, so that they are detachably connected, which facilitates the connection of different temperature detectors 3, and increases the adaptability and practicality of the application to different temperature detectors 3.

[0025] It should be noted that the aforementioned temperature detector 3 is a existing deep temperature detector 3, and can also be a double-metal remote temperature meter, and the type and parameters of the temperature detector 3 are not specifically limited in the embodiment. In addition, Figure 1 Two temperature detectors 3 are shown in the figure, and the number of temperature detectors 3 can be adaptively adjusted according to actual needs, and the embodiment does not specifically limit this.

[0026] In summary, the temperature detection device of the oil cooler provided by the application sets a structure for cleaning the impurities on the surface of the temperature detector 3, which improves the accuracy of temperature detection of the temperature detector 3, that is, reduces the measurement error, and further improves the temperature detection performance of the oil cooler.

[0027] Finally, the utility model provides a kind of oil cooler temperature detection device, comprising: mounting head 1, with the connector 2 of the bottom surface solid connection of mounting head 1, with the temperature detector 3 of the bottom surface connection of connector 2, the centre of mounting head 1 is equipped with bolt 4, the head of bolt 4 is hexagon nut and protrudes from the top surface of mounting head 1;The bolt 4 is connected with the connector 2 by sealing structure 5 after passing through the connector 2, the bottom end of bolt 4 is equipped with multiple wave-shaped brush 6, and the part of the outside bristle of brush 6 is attached to the surface of temperature detector 3.The utility model is equipped with the structure of cleaning temperature detector 3 surface impurity, improves the accuracy of temperature detector 3 detection temperature, i.e.
