[0003] According to Chinese patent publication number CN208816983U, a lubricating oil pump device includes a motor, and the output shaft of the motor is fixedly connected to a coupling. The lubricating oil pump device, through the provision of an air inlet nozzle, and the coordinated provision of a sealing plug, a first air pipe, a three-way pipe, a second air pipe, a clamping block and an air bag, enables the gas in the air bag to flow from the second air pipe into the three-way pipe when the sealing plug is pulled out, so that the gas in the three-way pipe can flow out of the air inlet nozzle through the first air pipe, so that the clamping block can take the air bag out of the clamping slot after the air bag has exhausted the gas.

[0004] A lubricating oil pump is a commonly used device that, driven by an electric motor, raises the lubricating oil raw material to a certain pressure and supplies the lubricating oil raw material to production equipment through an oil circuit. The lubricating oil pump will become too hot as it runs for too long, and working in an environment with too high an ambient temperature may also cause the lubricating oil pump temperature to rise and overheat, which can easily affect the normal operation of the lubricating oil pump. Therefore, a lubricating oil pump with an overheating protection function is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-3 In this embodiment, a lubricating oil pump with an overheat protection function includes a lubricating oil pump body 2, a base 1 is fixedly installed at the bottom of the lubricating oil pump body 2, a monitoring component is arranged on the base 1, and a heat dissipation component is arranged on the base 1.

[0024] The monitoring component includes a protective cover 6, one side of which is provided with an embedding groove 7, the interior of which is detachably mounted with an embedding plate 8 via bolts, one side of which is mounted with an infrared temperature sensor 9, the infrared temperature sensor 9 is located inside the protective cover 6, and an adjustment member is provided at the bottom of the protective cover 6.

[0025] See also Figure 1 , Figure 2 , Figure 3 The adjusting member includes a supporting slider 11 and a threaded rod 12. The supporting slider 11 is fixedly connected to the bottom of the protective cover 6. The threaded rod 12 is rotatably connected to a slide groove 13 opened at the top of the base 1. The supporting slider 11 is threadedly connected to the outside of the threaded rod 12. One end of the threaded rod 12 passes through the base 1 and extends to the outside and is fixedly connected to a rotating rod 14. The supporting slider 11 is slidably connected to the inside of the slide groove 13. The supporting slider 11 is a rectangular block.

[0026] It can be understood that the position of the protective cover 6 can be easily adjusted through the adjustment piece, and the protective cover 6 can be removed from one end of the lubricating oil pump body 2 to facilitate maintenance of the lubricating oil pump body 2. The embedded plate 8 is fixed to the protective cover 6 by bolts, which makes it easy to remove the infrared temperature sensor 9 from the protective cover 6 and facilitate maintenance of the infrared temperature sensor 9.

[0027] The heat dissipation assembly includes a support plate 3 , on which a heat dissipation fan 5 is arranged. A groove is formed at the bottom of the support plate 3 , inside of which a vertical plate 4 is rotatably connected. The vertical plate 4 is fixedly mounted on the top of the base 1 .

[0028] A limit member for fixing the support plate 3 is provided on the vertical plate 4, and the limit member includes a rotating rod 16, which is fixed inside the vertical plate 4, and two limit plates 15 are sleeved on the outside of the rotating rod 16, and the vertical plate 4 is located between the two limit plates 15. The rotating rod 16 is a "T"-shaped rod, and the external thread of the rotating rod 16 is connected to an annular pressure plate 17, and an arc rod 18 is fixedly connected to one side of the annular pressure plate 17.

[0029] The two limiting plates 15 are respectively attached to the front and rear sides of the support plate 3 , and the vertical plate 4 and the support plate 3 have the same thickness.

[0030] It should be noted that, by providing a limiting member, the support plate 3 is limited so that it is in a perpendicular state to the base 1 , and there are two support plates 3 , which are respectively located at the front and rear sides of the base 1 .

[0031] See also Figure 1 , Figure 4 A controller 10 is fixedly mounted on the top of the protective cover 6 , the interior of the protective cover 6 is a cavity structure, and the protective cover 6 is arranged outside one end of the lubricating oil pump body 2 .

[0032] It should be noted that the infrared temperature sensor 9 and the cooling fan 5 are both electrically connected to the controller 10. The infrared temperature sensor 9 monitors the temperature of the lubricating oil pump body 2 in real time during operation. If the temperature of the lubricating oil pump body 2 rises to the set value of the infrared temperature sensor 9, a signal will be transmitted to the controller 10, so that the controller 10 controls the cooling fan 5 to dissipate heat and cool down the lubricating oil pump body 2, thereby achieving the effect of overheating protection.

[0033] The working principle of the above embodiment is as follows: when in use, the temperature of the lubricating oil pump body 2 during operation is monitored in real time through the infrared temperature sensor 9. If the temperature of the lubricating oil pump body 2 rises to the set value of the infrared temperature sensor 9, a signal will be transmitted to the controller 10, so that the controller 10 controls the cooling fan 5 to dissipate heat and cool the lubricating oil pump body 2, thereby ensuring the normal operation of the lubricating oil pump body 2 and playing the role of overheating protection. The protective cover 6 plays a protective effect on the infrared temperature sensor 9 to prevent the infrared temperature sensor 9 from being affected by environmental uncertainties and affecting the accuracy of detection. If the lubricating oil pump body 2 needs to be maintained and repaired, the arc rod 18 is rotated to drive the annular pressure plate 17 to rotate away from the vertical plate 4, so that the limit plate 15 can be rotated to move away from the surface of the support plate 3, and the support plate 3 can be flipped to expose the lubricating oil pump body 2, and then the rotating rod 14 is rotated to drive the threaded rod 12 to rotate, so that the support slider 11 can slide and drive the protective cover 6 to move away from the tail end of the lubricating oil pump body 2.
