[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figure 1 As shown, the terminal detection centralized lubrication system of the embodiment of the utility model comprises a container 1, a conveying system 2 and a plurality of detection devices 3. The container 1 is used to store grease, and the container 1 can be a box, a tank or other device capable of storing grease.

[0028] The delivery system 2 is connected to the container 1 and comprises a plurality of supply ends for discharging the grease, and a plurality of detection devices 3 are arranged at at least some of the supply ends. Figure 1 As shown, the delivery system 2 may include corresponding pipelines, a delivery pump 21, a mother distributor 22, a sub-distributor 23, etc. The inlet of the delivery pump 21 may be directly connected to the container 1, there may be multiple mother distributors 22 and they may all be connected downstream of the delivery pump 21, each mother distributor 22 may be provided with multiple sub-distributors 23, and multiple sub-distributors 23 may all be connected downstream of the corresponding mother distributor 22. The multiple outlets of each sub-distributor 23 may be extended to the corresponding friction pair (lubrication point) through a pipeline respectively, and the end of the pipeline is used for the discharge of grease and forms the above-mentioned supply end. In some other embodiments, the grease may also be lubricating oil, etc.

[0029] like Figure 1 As shown, the supply end may be connected to a detection device 3. Figure 2 As shown, the detection device 3 may include a connector 31 , a magnet 32 , an elastic member 33 and an induction member 34 .

[0030] The joint 31 is provided with an inner hole 311 for grease to flow, and the induction element 34 is arranged in the side wall of the joint 31. Figure 2As shown, the joint 31 can be generally a tubular structure and can extend in the left-right direction, and the inner hole 311 is provided inside the joint 31 and penetrates the joint 31 in the left-right direction. When in use, the grease can flow into the inner hole 311 from the left port of the joint 31, and then flow out from the right port of the inner hole 311 and be supplied to the corresponding friction pair.

[0031] The connector 31 is made of a non-magnetic material, thereby reducing the impact on the detection of the sensing element 34 and facilitating improving the detection accuracy.

[0032] The sensing element 34 can be embedded in the circumferential side wall of the joint 31 , and the sensing element 34 does not contact the grease in the inner hole 311 , thereby preventing the grease from damaging the sensing element 34 and playing a protective role.

[0033] The magnet 32 is provided with a through hole for the grease to pass through, and the magnet 32 is slidably fitted in the inner hole 311 and moves relative to the induction member 34 under the hydraulic action of the grease. For example, the magnet 32 as a whole can be annular, and the magnet 32 can be slidably fitted in the inner hole 311. When the grease is passed into the inner hole 311, due to the difference between the aperture of the through hole of the magnet 32 and the aperture of the inner hole 311, a pressure difference will be formed on the left and right sides of the magnet 32 due to the action of the grease, and under the action of this pressure difference, the magnet 32 will move to the right.

[0034] The sensing element 34 is used to detect the hydraulic value of the grease by monitoring the distance change between the sensing element 34 and the magnet 32. For example, when the grease is not passed into the inner hole 311, the magnet 32 can fit with the sensing element 34. When the grease is passed into the inner hole 311, the magnet 32 will move rightward under the action of the grease, so that the magnet 32 will move away from the sensing element 34. This distance change will cause the magnetic field between the sensing element 34 and the magnet 32 to change. The sensing element 34 can monitor this magnetic field change, and then indirectly measure the hydraulic effect of the grease on the magnet 32. The sensing element 34 can be specifically a Hall sensor.

[0035] When the grease flow rate is large, the hydraulic pressure applied to the magnet 32 is large. At this time, the distance between the magnet 32 and the induction member 34 will be large. Conversely, the distance between the magnet 32 and the induction member 34 will be small. The monitoring of the position of the magnet 32 by the induction member 34 can reflect the grease flow rate, and then the amount of grease discharged from the outlet of the connector 31 can be determined, thereby realizing the monitoring of the grease supply amount.

[0036] The elastic member 33 acts between the magnet 32 and the joint 31 and is used to reset the magnet 32 to the induction member 34. Figure 2As shown, the elastic member 33 can be stopped between the magnet 32 and the joint 31 , and the elastic member 33 can exert elastic force on the magnet 32 , so that the magnet 32 can be reset to the initial position when no grease is introduced into the inner hole 311 .

[0037] In some embodiments, the terminal detection centralized lubrication system may further include an alarm module. When the supply amount of grease detected by the detection device 3 is small, the alarm module may sound an alarm after receiving a corresponding signal, thereby enabling the staff to perform timely inspection and maintenance.

[0038] In some embodiments, the connector 31 is provided with a first stopper 312 and a second stopper 313 protruding from the hole wall of the inner hole 311, the first stopper 312 is located upstream of the second stopper 313, and the sensor 34 is disposed in the first stopper 312, for example, Figure 2 As shown, the first stopper 312 and the second stopper 313 can be integrally formed on the inner peripheral wall of the connector 31, wherein the first stopper 312 can be located on the left side of the second stopper 313. The induction member 34 can be assembled into the first stopper 312 from the outside of the connector 31. The magnet 32 is slidably fitted between the first stopper 312 and the second stopper 313.

[0039] Therefore, on the one hand, it can limit the moving stroke of the magnet 32, and on the other hand, it can make the induction member 34 and the magnet 32 relatively arranged in the axial direction of the joint 31, so as to facilitate the monitoring of the relative position of the induction member 34 and the magnet 32.

[0040] In some embodiments, Figure 2 As shown, the elastic member 33 is disposed between the magnet 32 and the second stopper 313. When in use, the elastic member 33 can push the magnet 32 to the left, so that the magnet 32 in a normal state can be in close contact with the first stopper 312.

[0041] In some embodiments, the second stopper 313 can be fixed in the joint 31 by means of screw assembly or the like, thereby facilitating the installation and removal of the magnet 32 and the elastic member 33 .

[0042] In some embodiments, the first stopper 312 and the second stopper 313 are both extended and closed in a circle along the circumference of the joint 31. For example, the first stopper 312 and the second stopper 313 can be annular, so as to ensure the consistency of the circumferential structure and the stability of the interaction with the magnet 32 and the elastic member 33.

[0043] In some embodiments, the first stopper 312 and the second stopper 313 are both annular, and the inner diameter of the first stopper 312 is consistent with the inner diameter of the second stopper 313. This helps to reduce the large flow rate change caused by the inconsistent inner diameters of the first stopper 312 and the second stopper 313.

[0044] In some embodiments, Figure 2 As shown, the outlet of the connector 31 is located downstream of the second stopper 313, and the cross section of the outlet gradually increases in the direction away from the second stopper 313. This is beneficial to expand the spraying range of the grease and improve the lubrication effect.

[0045] In some embodiments, the elastic member 33 is a spring and is coaxially arranged with the magnet 32, and the diameter of the through hole is smaller than the inner diameter of the spring, so that the grease can flow more smoothly in the spring, avoiding the situation where the smaller inner diameter of the spring has a greater impact on the flow of the grease.

[0046] In some embodiments, the connector 31 is provided with an assembly hole, the assembly hole extends into the second stopper 313, and the orifice of the assembly hole is located on the outer peripheral wall of the connector 31, and the sensor 34 is detachably assembled in the assembly hole. This facilitates the assembly of the sensor 34 to the second stopper 313 from the outer peripheral side of the connector 31.

[0047] In some embodiments, Figure 2 As shown, the terminal detection centralized lubrication system includes a tube body 35, and a sensing member 34 is arranged at one end of the tube body 35. The tube body 35 is threadedly matched in the assembly hole, and the tube body 35 is used for the wire connected to the sensing member 34 to pass through. This facilitates the installation and arrangement of the sensing member 34, and the tube body 35 can also play a role in fixing the installed sensing member 34. In addition, since the tube body 35 is threadedly matched with the assembly hole, the depth of the tube body 35 inserted into the assembly hole can be adjusted, so that the radial position of the sensing member 34 along the joint 31 can be adjusted, which can play a role in correcting the position of the sensing member 34.

[0048] Although the above embodiments have been shown and described, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
