Description

Technical Field

[0001] This utility model relates to the field of hydraulic damper technology, specifically to a hydraulic damper oil leakage detection device. Background Technology

[0002] Hydraulic dampers are commonly used equipment in many power plants. During the operation of the power plant, hydraulic oil leakage is prone to occur in the dampers, so oil leakage detection devices are needed.

[0003] The existing utility model patent document number CN218847534U discloses an oil leakage detection device for a large-tonnage hydraulic damper. By setting an oil passage water-blocking component, when rainwater enters the oil collection bottle through the oil passage hole on rainy days, the water-blocking component will keep the rainwater on the oil passage water-blocking component and prevent it from falling to the bottom of the oil collection bottle. As a result, the piezoelectric sensor will not react, thus preventing rainwater from entering the bottom of the oil collection bottle and reacting with the piezoelectric sensor, thereby avoiding false alarms from the warning device. However, the oil collection bottle of this oil leakage detection device needs to be set close to the oil collection tank and the hydraulic damper body, making it difficult to apply in places with insufficient space, thus affecting the scope of use. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a hydraulic damper oil leakage detection device to solve the problems mentioned in the background art.

[0005] A hydraulic damper oil leakage detection device includes an oil collection bottle and a top cover disposed on top of it. The top cover has an oil passage hole at its upper end, and an infrared sensor is installed in the middle of the upper end of the top cover. A piezoelectric sensor is installed on the bottom wall of the oil collection bottle. One side of the infrared sensor and the piezoelectric sensor is connected to an early warning device via a wire. An oil-passing and water-blocking assembly communicating with the oil passage hole is installed at the upper end of the top cover. An oil passage pipe communicating with the oil passage hole is connected to the upper end of the oil-passing and water-blocking assembly. An oil collection groove is provided on one side of the oil collection bottle. The hydraulic damper body is fixed inside the oil collection groove. An oil drain pipe is fixed through the right end of the oil collection groove. A hose assembly is connected between the end of the oil drain pipe and the end of the oil passage pipe.

[0006] Furthermore, the oil-water-blocking assembly includes a housing and an oil-water-blocking component. The housing is fixed to the top cover. The lower part of the housing has a connecting hole, which is located on the same vertical line as the oil passage hole. The oil passage pipe is connected to the housing. The oil-water-blocking component is slidably connected inside the housing. The oil-water-blocking component includes a mesh frame and an oil-water-blocking mesh. The mesh frame is slidably connected inside the housing. The front part of the mesh frame moves through the housing. The oil-water-blocking mesh is fixed inside the mesh frame.

[0007] Furthermore, a fixing hoop is fixed to the surface of the hydraulic damper body. The two ends of the fixing hoop are located above the oil collection groove. A row of screw holes is opened on both the front and rear sides of the upper end of the oil collection groove. Bolts are threadedly connected between the fixing hoop and the screw holes on the same vertical line.

[0008] Furthermore, the hose assembly includes a hose, a fitting, and a nut. There is a pair of fittings connected to both ends of the hose, and a pair of nuts threadedly connected to the outside of the fittings. The two fittings are connected to the drain pipe and the through pipe, respectively.

[0009] Furthermore, both the drain pipe and the through pipe have threads on their outer walls, and the two nuts are threadedly connected to the drain pipe and the through pipe, respectively.

[0010] Furthermore, a first plug is fixed to the outer side of the end of the oil pipe, and a second plug is fixed to the outer side of the end of the oil drain pipe. The outer diameters of the first plug and the second plug are equal to the inner diameters of the pipe joints. The first plug and the second plug are respectively inserted into the two pipe joints.

[0011] The beneficial effects of this utility model are as follows: By improving the contact installation of the oil collection tank and the oil collection bottle to a separate installation of the oil collection tank and the oil collection bottle through a hose, the oil collection bottle does not need to be installed close to the oil collection tank and the hydraulic damper body. This allows the oil collection bottle to be placed in a limited space. Only the oil collection tank and the hydraulic damper body need to be fixed. This makes it applicable in places with insufficient space and improves the scope of use. Attached Figure Description

Detailed Implementation

[0016] Please see Figures 1-3An oil leakage detection device for a hydraulic damper includes an oil collection bottle 1 and a top cover 2 disposed on top of it. The top cover 2 has an oil passage hole at its upper end. An infrared sensor 14 is installed in the middle of the upper end of the top cover 2. A piezoelectric sensor is installed on the bottom wall of the oil collection bottle 1. An early warning device 15 is connected to one side of the infrared sensor 14 and the piezoelectric sensor via a wire. An oil-water blocking assembly communicating with the oil passage hole is installed on the upper end of the top cover 2. An oil-water blocking assembly is connected to an oil passage pipe 5 communicating with it at its upper end. The oil-water blocking assembly includes a housing 3 and an oil-water blocking component 4. The housing 3 is fixed to the top cover 2. A connecting hole is provided at the lower part of the housing 3, and the connecting hole communicates with the oil passage hole. The oil holes are located on the same vertical line. The oil pipe 5 is connected to the box body 3. The oil-water blocking component 4 is slidably connected inside the box body 3. The oil-water blocking component 4 includes a mesh frame and an oil-water blocking net. The mesh frame is slidably connected inside the box body 3. The front part of the mesh frame moves through the box body 3. The oil-water blocking net is fixed inside the mesh frame. When oil enters the box body 3 along the oil pipe 5, it will pass through the oil-water blocking net and then enter the oil collection bottle 1 along the connecting hole and the oil hole. As a result, the piezoelectric sensor will react, causing the alarm device 15 to sound an alarm. The oil-water blocking net, piezoelectric sensor, infrared sensor 14 and alarm device 15 are all existing technologies, so the specific principles will not be elaborated in detail.

[0017] The oil collecting bottle 1 has an oil collecting trough 8 on one side. A hydraulic damper body 7 is fixed inside the oil collecting trough 8. A fixing hoop 9 is fixed on the surface of the hydraulic damper body 7. The two ends of the fixing hoop 9 are located above the oil collecting trough 8. A row of screw holes 10 is opened on both the front and rear sides of the upper end of the oil collecting trough 8. The fixing hoop 9 is threadedly connected to the screw holes 10 on the same vertical line with bolts. When the hydraulic damper body 7 is located inside the oil collecting trough 8, the fixing hoop 9 is placed on the oil collecting trough 8. Then, the bolts are aligned with the screw holes 10 and screwed in to fix the fixing hoop 9, thereby fixing the hydraulic damper body 7 inside the oil collecting trough 8.

[0018] An oil drain pipe 11 is fixedly connected to the right end of the oil collection tank 8. A hose assembly is connected between the oil drain pipe 11 and the end of the oil passage pipe 5. The hose assembly includes a hose 13, a pipe connector 16, and a nut 17. There is a pair of pipe connectors 16, which are respectively connected to both ends of the hose 13. There is a pair of nuts 17, which are threadedly connected to the outside of the pipe connectors 16. The two pipe connectors 16 are respectively connected to the oil drain pipe 11 and the oil passage pipe 5. The outer walls of the oil drain pipe 11 and the oil passage pipe 5 are both threaded. The two nuts 17 are respectively threaded to the oil drain pipe 11 and the oil passage pipe 5. When connecting the oil collection tank 8 to the oil collection bottle 1, one pipe connector 16 is aligned with the oil drain pipe 11, and the other pipe connector 16 is aligned with the oil passage pipe 5. Correspondingly, rotate the two nuts 17 respectively, so that the nuts 17 are rotated between the pipe joint 16 and the oil passage pipe 5, and between the pipe joint 16 and the drain pipe 11, to complete the connection. This allows the oil leaking from the hydraulic damper body 7 to flow along the drain pipe 11 into the hose 13, then into the oil passage pipe 5, and finally into the oil collection bottle 1. This improves the contact installation of the oil collection tank 8 and the oil collection bottle 1 to a separate installation of the oil collection tank 8 and the oil collection bottle 1 through the hose 13. In this way, the oil collection bottle 1 does not need to be installed close to the oil collection tank 8 and the hydraulic damper body 7, so that the oil collection bottle 1 can be placed in a limited space. Only the oil collection tank 8 and the hydraulic damper body 7 need to be fixed. This can also be used in places with insufficient space, thus improving the scope of application.

[0019] A first plug 6 is fixed to the outer side of the end of the oil passage pipe 5, and a second plug 12 is fixed to the outer side of the end of the oil drain pipe 11. The outer diameters of the first plug 6 and the second plug 12 are equal to the inner diameter of the pipe joint 16. The first plug 6 and the second plug 12 are respectively inserted into the two pipe joints 16. When one pipe joint 16 is aligned with the oil drain pipe 11 and the other pipe joint 16 is aligned with the oil passage pipe 5, the first plug 6 can be inserted into one pipe joint 16 and the second plug 12 can be inserted into the other pipe joint 16, which serves as a connection.
