[0002] Hydraulic power machinery is a type of mechanical equipment that uses liquid as a power transmission medium. They use the hydraulic principle to transmit energy and control movement. The hydraulic system consists of hydraulic fluid, hydraulic pump, hydraulic motor or hydraulic cylinder, valve, pipeline and control components. Leakage may cause system pressure drop, performance degradation and environmental pollution. Through timely detection and alarm, potential dangers and losses can be prevented, so hydraulic power machinery oil leakage protection devices are needed.
[0003] During the use of traditional hydraulic power machinery oil leakage protection devices, when oil leakage occurs in the hydraulic oil pipeline, the hydraulic oil in the hydraulic oil tank will gradually decrease. When the cylindrical floating body moves to the adsorption magnet as the oil drops, the adsorption magnet and the cylindrical floating body attract each other, allowing the two contacts to contact. At this time, the circuit is turned on and an alarm is given.
[0004] However, it does not solve the problem that the cylindrical floating body floats freely inside the support tube and cannot be limited. When the equipment shakes during operation, the floating body is easily stuck inside the support tube, resulting in the inability to detect oil leakage in time. Utility Model Content

When the equipment shakes during operation, the floating body is easily stuck inside the supporting tube, resulting in the problem that oil leakage cannot be discovered in time.

[0031] 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.
[0032] Reference Figure 1-Figure 3, an embodiment provided by the utility model: a hydraulic power machinery oil leakage protection device, comprising a shell 1, a support cylinder 2 is fixedly connected inside the shell 1, a symmetrically arranged support plate 23 is fixedly connected inside the support cylinder 2, a support column 4 is fixedly connected on one side of the support plate 23, a limiting groove 5 is provided inside the support column 4, a floating column 6 is slidably connected to the outer wall of the support column 4, a limiting assembly is provided inside the floating column 6, a rotating roller 9 is rotatably connected inside the limiting assembly, the outer wall of the rotating roller 9 is fitted inside the limiting groove 5, a cavity 7 is provided inside the floating column 6, an observation window 3 is provided inside the support cylinder 2, a support block 10 is fixedly connected to the outer wall of the shell 1, a controller 11 is fixedly connected to one side of the support block 10, an ultrasonic sensor 12 is fixedly connected to one side of the support block 10, and one side of the ultrasonic sensor 12 is fitted to the outer wall of the support cylinder 2, the limiting assembly comprises a limiting block 8, one side of the limiting block 8 is fixedly connected to the inside of the floating column 6, the outer wall of the limiting block 8 is slidably connected to the inside of the limiting groove 5, and both ends of the rotating roller 9 are rotatably connected to the inside of the limiting block 8;
[0033] Specifically, when an oil leak occurs, the floating column 6 cooperates with the limiting groove 5 through the internal limiting block 8 to ensure its stable floating in the hydraulic oil. This is because the cavity 7 inside the floating column 6 allows it to float freely in the hydraulic oil. At the same time, the floating column 6 is also connected to the support column 4, and its position is limited by the support column 4. When the amount of hydraulic oil decreases, the floating column 6 will drop as the liquid level of the hydraulic oil changes. In order to reduce friction, a rotating roller 9 is set between the limiting block 8 and the support column 4. In this way, the floating column 6 can move smoothly even when the hydraulic oil is reduced. In order to ensure safety, when the floating column 6 drops to the warning position, the ultrasonic sensor 12 will monitor it in real time. Once it is detected that the floating column 6 is in the warning position, the controller 11 will start immediately and send a warning signal to the system to remind the operator to deal with it in time.
[0034] Reference Figure 1 , Figure 4 and Figure 5 The top of the shell 1 is fixedly connected with an oil filling pipe 13, the outer wall of the oil filling pipe 13 is threadedly connected with a sealing cover 14, the inside of the oil filling pipe 13 is fixedly connected with a positioning block 18, a limit plate 19 is arranged inside the oil filling pipe 13, a positioning groove 20 is opened inside the limit plate 19, the outer wall of the limit plate 19 is slidably connected to the outer wall of the positioning block 18 through the positioning groove 20, a partition plate 24 is fixedly connected to the inside of the oil filling pipe 13, a frame 15 is arranged inside the oil filling pipe 13, a filter screen 17 is fixedly connected inside the frame 15, a card slot 16 is opened inside the frame 15, a hemispherical column 21 is fixedly connected to one side of the limit plate 19, the outer wall of the hemispherical column 21 is embedded in the card slot 16, a spring 22 is arranged inside the oil filling pipe 13, one end of the spring 22 is fixedly connected to the other side of the limit plate 19, and the other end of the spring 22 is fixedly connected to the inside of the oil filling pipe 13;
[0035] Specifically, when adding hydraulic oil, first, open the sealing cover 14, and insert the filter 17 into the oil filling pipe 13 through the frame 15. The function of the filter 17 is to filter impurities in the hydraulic oil and ensure the cleanliness of the hydraulic oil. Next, the filter 17 is limited by the frame 15. The limitation is to prevent the filter 17 from shifting under the action of the hydraulic oil, thereby ensuring the filtering effect. The frame 15 is limited by the partition 24, so that the position of the filter 17 can be ensured to be stable. After the filter 17 is installed, the hemispherical column 21 is embedded in the slot 16. The embedding of the hemispherical column 21 and the slot 16 can limit the frame 15 and further ensure the flow direction of the hydraulic oil. At the same time, the hemispherical column 21 is limited by the limiting plate 19 inside the oil filling pipe 13, so that the hemispherical column 21 can be prevented from shifting under the action of the hydraulic oil. In order to make the hemispherical column 21 more stable, it is supported by the tension of the spring 22. Under the action of the spring 22, the hemispherical column 21 is not easy to slide out when it is inserted into the slot 16, thereby ensuring the smooth flow of the hydraulic oil. After the above steps are completed, add hydraulic oil to the hydraulic equipment. After adding, reinstall the sealing cover 14 to protect the hydraulic system from external contamination.
[0036] Working principle: When the hydraulic power machinery oil leakage protection device is used, when the hydraulic oil needs to be filled first, the sealing cover 14 is opened and then the filter screen 17 is inserted into the oil filling pipe 13 through the frame 15. The frame 15 is limited by the partition 24. Then the hemispherical column 21 inside the oil filling pipe 13 is embedded in the card slot 16 to limit the frame 15. The hemispherical column 21 is limited inside the oil filling pipe 13 by the limiting plate 19. The limiting plate 19 is further limited on the outer wall of the positioning block 18 through the positioning groove 20. Then the hemispherical column 21 is supported by the tension of the spring 22, so that the hemispherical column 21 is not easy to slide out when it is embedded in the card slot 16. Then, when the oil leakage occurs, the hemispherical column 21 is Since the support cylinder 2 is connected to the shell 1, the hydraulic oil will also be reflected through the floating column 6. The floating column 6 is limited in the limiting groove 5 by the internal limiting block 8. The cavity 7 opened in the floating column 6 can make the floating column 6 float in the hydraulic oil. Since the floating column 6 is limited by the support column 4, when the hydraulic oil is reduced, the floating column 6 will also change with the liquid level of the hydraulic oil. The friction between the limiting block 8 and the support column 4 is reduced by rotating the roller 9. Then, when the floating column 6 is lowered to the warning position, the ultrasonic sensor 12 will detect whether the floating column 6 is in the warning position, and the controller 11 will control it to issue a warning to remind the operator.
