Description

Technical Field

[0001] This invention relates to the field of oil level monitoring technology, and more specifically, to an intelligent lubrication system pump station oil level monitor. Background Technology

[0002] Oil level detectors, as a common liquid level detection instrument, are widely used in various industries. Conventional oil level detectors use the principle of communicating vessels to display the liquid level. Through the connection of the bottom connecting hole, the liquid level inside the detector is made level with the liquid level inside the oil tank under pressure, thus displaying the liquid level.

[0003] Because the bottom of the detector is connected to the bottom of the oil tank, oil and other impurities accumulate and settle over a long period of time, with most of them settling at the bottom of the container. This means that a conventional oil level detector would be working in an environment full of impurities, which would easily clog the bottom connecting hole, causing delays or errors in the normal display of the oil level and making it difficult to accurately judge the residual oil in the oil tank.

[0004] Therefore, an oil level monitor is needed to solve the problem of blockage in the detector's connecting hole. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent lubrication system pump station oil level monitor.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An intelligent lubrication system pump station oil level monitor includes a transparent and visible liquid level tube. The top of the liquid level tube is fixedly connected to a top passage communicating with the top of an oil tank, and the lower side is fixedly connected to a connecting pipe communicating with the bottom of the oil tank. The feature is that a buoy is provided inside the liquid level tube and floats along the liquid level tube. A tether is attached to the bottom of the buoy, and brush balls are evenly spaced on the surface of the tether. The tail end of the tether is wound up by a winder provided at the tail end of the connecting pipe. The brush balls move along the inside of the connecting pipe to clean the surface through the floating of the buoy and the winding action of the winder. A sludge collection tank is provided at the front end of the connecting pipe to collect sludge.

[0008] As a further aspect of the present invention: the liquid level tube includes a housing and a visual tube. The housing is a rigid housing, and the inner side is wrapped with a transparent visual tube. A strip-shaped viewing window is opened on the front of the housing, and a scale is marked on one side of the window.

[0009] As a further aspect of the present invention: a bracket is provided at the connection between the liquid level pipe and the connecting pipe. The bracket includes a ring body and a support plate. The ring body is an annular structure with the same inner diameter as the liquid level pipe and the connecting pipe. It is connected between the liquid level pipe and the connecting pipe. The inner wall has annularly distributed petal-shaped support plates protruding towards the center. Adjacent support plates are spaced apart. The minimum inner diameter of the support plate is smaller than the diameter of the buoy.

[0010] As a further embodiment of the present invention: the connecting pipe is a tree-shaped pipe, with a flange in the middle section for connection to the bottom of the oil tank, and the connecting pipe between the flange and the liquid level pipe is set at an angle of 5° to the horizontal plane, with the front end connecting to the liquid level pipe at a low position.

[0011] As a further aspect of the present invention: an annular guide ring is provided on the lower inner wall of the bend in the connecting pipe at the connection point between the front end of the connecting pipe and the liquid level pipe, and a tethering rope passes through the guide ring.

[0012] As a further aspect of the present invention: the connection between the brush ball and the cord is spindle-shaped and arranged along the direction of the cord.

[0013] As a further embodiment of the present invention: a pin-triggered connecting valve is provided at the front end of the connecting pipe, the connecting valve is located on the lower side of the connection position between the connecting pipe and the liquid level pipe, and a sludge collection tank with a pin is connected to the lower side of the connecting valve by a thread.

[0014] As a further embodiment of the present invention: the connecting valve includes a valve body, the top of the valve body is connected to the connecting pipe, and a valve disc is slidably connected to the center of the valve body through a valve stem. A pressure spring is provided between the valve disc and the valve body to act on the valve disc so that the valve disc closes the bottom opening of the valve body. The sludge collection tank includes a tank body and a pin. A through-hole is provided at the top of the tank body, and a protruding pin is provided in the center of the through-hole. The position of the pin corresponds to the valve disc.

[0015] As a further aspect of the present invention: a sealing ring is provided at the position where the valve body connects to the tank body, and when the sludge collection tank is connected to the connecting valve, the depth to which the sealing ring penetrates the tank structure is greater than the depth to which the ejector pin penetrates the valve body.

[0016] As a further aspect of the present invention: a spool is rotatably arranged inside the winding device, the tail end of the tether rope is connected to the spool, and a coil spring is provided inside the spool to drive the spool to rotate and wind up the tether rope. The winding position is located on the lower side of the spool.

[0017] Beneficial effects:

[0018] 1. The present invention provides a float that floats along the liquid level tube inside the liquid level tube. A rope is attached to the bottom of the float. Brush balls are evenly spaced on the surface of the rope. The tail end of the rope is wound up by a winder at the tail end of the connecting tube. The brush balls move and clean along the inside of the connecting tube by the floating of the float and the winding action of the winder. The self-cleaning of the bottom connecting tube is achieved by the buoyancy change brought about by the oil surface and the winding action at the tail end.

[0019] 2. In this invention, an annular guide ring is provided on the lower inner wall of the bend in the connecting pipe at the connection point between the front end of the connecting pipe and the liquid level pipe. The tether rope passes through the guide ring. The guide ring guides the position of the tether rope and the brush ball, preventing the tether rope and the brush ball from moving against the top of the connecting pipe due to the force of the buoy. Instead, the tether rope and the brush ball pass along the lower side of the connecting pipe, which can better clean the impurities deposited at the bottom. In addition, the connection part between the brush ball and the tether rope is spindle-shaped and arranged along the direction of the tether rope. The spindle-shaped structure allows the connection position of the brush ball and the tether rope to be better guided into the guide ring and pass through, preventing the brush ball from getting stuck at the guide ring.

[0020] 3. The front end of the connecting pipe of the present invention is provided with a pin-triggered connecting valve. The connecting valve is located on the lower side of the connection position between the connecting pipe and the liquid level pipe. The lower side of the connecting valve is connected to a sludge collection tank with a pin by a thread. With the setting of the pin-triggered connecting valve and the sludge collection tank, when the brush ball sweeps the impurities to the position of the connecting valve, they will fall into the sludge collection tank and be collected, avoiding the accumulation of impurities at the front end of the connecting pipe. The pin-triggered connecting valve can also seal the opening when the sludge collection tank is removed for cleaning, preventing oil leakage. It can also automatically open the oil circuit after the sludge collection tank is installed, simplifying operation. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-7 , Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present invention; Figure 2 This is a schematic diagram of the liquid level tube structure of the present invention; Figure 3 For the present invention Figure 2 Enlarged schematic diagram of the structure at point A; Figure 4 This is a schematic diagram of the bracket structure of the present invention; Figure 5 This is a cross-sectional view of the connecting pipe structure of the present invention; Figure 6 This is a schematic diagram of the rope connection of the present invention; Figure 7 This is a cross-sectional view of the connecting valve and the sludge collection tank of the present invention.

[0033] This embodiment provides an intelligent lubrication system pump station oil level monitor, including a transparent and visible liquid level pipe 1. The top of the liquid level pipe 1 is fixedly connected to a top passage 2 that communicates with the top of the oil tank, and the bottom is fixedly connected to a connecting pipe 3 that communicates with the bottom of the oil tank. The feature is that a float 7 is provided inside the liquid level pipe 1 and floats along the liquid level pipe 1. A tether rope 8 is attached to the bottom of the float 7. Brush balls 801 are evenly spaced on the surface of the tether rope 8. The tail end of the tether rope 8 is wound up by a winder 9 provided at the tail end of the connecting pipe 3. The brush balls 801 move and clean along the inside of the connecting pipe 3 by the floating of the float 7 and the winding action of the winder 9. A sludge collection tank 10 is provided at the front end of the connecting pipe 3 for sludge collection.

[0034] The liquid level tube 1 includes a housing 101 and a visual tube 102. The housing 101 is a rigid housing, and the inner side is wrapped with a transparent visual tube 102. A strip-shaped viewing window is opened on the front of the housing 101, and a scale is marked on one side of the window.

[0035] Among them, a bracket 5 is provided at the connection between the liquid level pipe 1 and the connecting pipe 3. The bracket 5 includes a ring body 501 and a support plate 502. The ring body 501 is an annular structure with the same inner diameter as the liquid level pipe 1 and the connecting pipe 3. It is connected between the liquid level pipe 1 and the connecting pipe 3. The inner wall has annularly distributed petal-shaped support plates 502 protruding towards the center. Adjacent support plates 502 are spaced apart. The minimum inner diameter of the support plate 502 is smaller than the diameter of the float 7.

[0036] By setting the bracket 5, the lowest position of the buoy 7 is limited, preventing the buoy 7 from entering the bend of the connecting pipe 3 when the liquid level is too low, and reducing the resistance to the buoy 7 rising due to the bend structure.

[0037] Among them, the connecting pipe 3 is a tree-shaped pipe, and a flange 4 is set in the middle section for connection with the bottom of the oil tank. The connecting pipe 3 between the flange 4 and the liquid level pipe 1 is set at an angle of 5° with the horizontal plane. The front end is connected to the liquid level pipe 1 at a low position. By using the overall tilt angle, it plays a guiding role for impurities, making it easier for them to accumulate at the front end 10, which is convenient for collection.

[0038] Among them, an annular guide ring 301 is provided on the lower inner wall of the bend of the connecting pipe 3 at the connection between the front end of the connecting pipe 3 and the liquid level pipe 1. The tether rope 8 passes through the guide ring 301. The guide ring 301 guides the position of the tether rope 8 and the brush ball 801, preventing the tether rope 8 and the brush ball 801 from moving against the top of the connecting pipe due to the force of the float 7. The tether rope 8 and the brush ball 801 pass against the lower side of the connecting pipe 3, which can better clean the impurities deposited at the bottom.

[0039] Specifically, the connection between the brush ball 801 and the cord 8 is spindle-shaped and arranged along the direction of the cord 8. The spindle-shaped structure allows the connection between the brush ball 801 and the cord 8 to be better guided into the guide ring 301 and pass through, preventing the brush ball 801 from being stuck at the guide ring 301.

[0040] The connecting pipe 3 is equipped with a pin-triggered connecting valve 6 at its front end. The connecting valve 6 is located on the lower side of the connection between the connecting pipe 3 and the liquid level pipe 1. The lower side of the connecting valve 6 is connected to a sludge collection tank 10 with a pin 1002 via a threaded connection.

[0041] Specifically, the connecting valve 6 includes a valve body 601, the top of which is connected to the connecting pipe 3. A valve disc 603 is slidably connected to the center of the valve body 601 via a valve stem 602. A pressure spring 604 is provided between the valve disc 603 and the valve body 601 to act on the valve disc 603 and close the bottom opening of the valve body 601. The sludge collection tank 10 includes a tank body 1001 and a pin 1002. A through-hole is provided at the top of the tank body 1001, and a protruding pin 1002 is provided in the center of the through-hole. The position of the pin 1002 corresponds to the valve disc 603.

[0042] With the pin-type connecting valve 6 and the sludge collection tank 10, when the brush ball 801 sweeps impurities to the position of the connecting valve 6, they will fall into the sludge collection tank 10 and be collected, preventing the accumulation of impurities at the front end of the connecting pipe 3. The pin-triggered connecting valve 6 can also seal the opening when the sludge collection tank 10 is removed for cleaning, preventing oil leakage. It can also automatically open the oil circuit after the sludge collection tank 10 is installed, simplifying operation.

[0043] Furthermore, a sealing ring 605 is provided at the position where the outer side of the valve body 601 connects with the tank body 1001. When the sludge collection tank 10 is connected to the connecting valve 6, the sealing ring 605 penetrates into the structure of the tank body 1001 to a greater depth than the pin 1002 penetrates into the valve body 601.

[0044] By adjusting the depth of the sealing ring 605 and the ejector pin 1002, the connection between the sealing ring 605 and the tank body 1001 precedes the triggering of the connecting valve 6 by the ejector pin 1002, ensuring that the sealing connection between the connecting valve 6 and the sludge collection tank 10 precedes the opening of the connecting valve 6, thus preventing leakage.

[0045] The winding device 9 has a rotating shaft 901 inside, and the tail end of the tether rope 8 is connected to the shaft 901. A coil spring is installed inside the shaft 901, which drives the shaft 901 to rotate and wind up the tether rope 8. The winding position is located on the lower side of the shaft 901, so that the winding device 9 is set higher than the connecting pipe 3. The pit at the bottom of the winding device 9 is level with the height of the connecting pipe 3, which facilitates the removal of impurities and prevents impurities from being rolled into the winding device 9 during winding and accumulating inside, making them impossible to clean.

[0046] When implementing the technical solution described in this embodiment, when the liquid level in the oil tank changes, the position of the float 7 in the level pipe 1 changes accordingly. Under the influence of buoyancy and the winding action of the tail-end retractor 9, the rope 8 in the connecting pipe 3 moves along the connecting pipe 3. The brush ball 801 fixed to the surface cleans the impurities deposited in the connecting pipe 3. The impurities, guided by the angle of the connecting pipe 3 and acted upon by the brush ball 801, move to the front connecting valve 6 and fall into the sludge collection tank 10 for collection, thus achieving self-cleaning of the bottom connecting pipe 3 and preventing blockage.
