The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. This embodiment is written in a progressive manner.
As shown in FIGS. 1-11, an intelligent oil leakage detection and recovery system for a heavy-duty equipment speed reducer is installed at the position of the oil leakage position of the speed reducer and comprises: the flexible main body 1 is provided with a depressed area 11 and connecting parts 12 positioned on two sides of the depressed area 11, the connecting parts 12 are connected with the speed reducer body, and the middle part of the depressed area 11 is provided with an opening end; in the specific implementation process, as shown in fig. 3, the two connecting portions 12 can make the whole flexible main body 1 fit to a leakage point at a plane position, collect oil from the leakage position through the recessed area 11, and guide the oil into the oil collecting tank 2; or, as shown in fig. 4, the flexible main body 1 has an annular structure by means of the two connecting portions 12, so that the flexible main body can surround the pipe body structure, collect oil at the oil leakage position of the pipe body structure, and guide the oil into the oil collecting tank 2.
The oil collecting tank 2 is connected with the bottom of the opening end at the notch and is used for collecting leaked oil; the bottom of the oil collecting tank 2 is provided with a sealing plate 21, the sealing plate 21 is rotatably connected with the tank body of the oil collecting tank 2, the bottom of the oil collecting tank 2 is sealed or opened through rotation, an open end for oil to flow out is formed when the bottom of the oil collecting tank 2 is opened, and the sealing plate 21 is connected with a pipeline 31 communicated with the oil tank 3 through a hole site; a filter plate 22 is arranged on one side of the sealing plate 21 in the groove body and is used for filtering oil entering the pipeline 31; an elastic connecting structure 23 is arranged between the sealing plate 21 and the trough body and used for tensioning the sealing plate 21 towards the trough body, an electromagnetic structure 24 is arranged at the bottom of the side wall of the trough body, the electromagnetic structure 24 is positioned at one side of the open end, and the electromagnetic structure 24 obtains magnetism when electrified and repels a first permanent magnet 26 on the sealing plate 21 to obtain the open end; a pressure induction sheet 25 is arranged between the binding surfaces of the sealing plate 21 and the filter plate 22, and the pressure value sensed by the pressure induction sheet 25 is used as the basis for controlling the electromagnetic structure 24 and the basis for detecting oil leakage.
During the working process, leaked oil enters the oil collecting tank 2, is filtered by the filter plate 22 and enters the oil tank 3 from the pipeline 31 to finally realize the recycling use, wherein the sealing at the bottom of the oil collecting tank 2 is realized by the tensioning action of the elastic connecting structure 23 on the sealing plate 21; when the pressure value sensed by the pressure sensing piece 25 is greater than the set value, it is indicated that the following two cases may occur:
the first condition is as follows: the filter holes on the filter plate 22 are blocked by impurities;
case two: the oil is leaked in a large amount and accumulated in the oil sump 2 in a short time after being led out from the pipeline 31.
No matter which kind of condition above taking place, all control system control electromagnetic structure 24 circular telegram, and make electro-magnet and first permanent magnet 26 produce the magnetic field of the same sex and repulse each other to make the cell body bottom obtain open and supply the accumulational impurity outflow or make accumulational fluid in time discharge on filter 22.
In the embodiment of the invention, whether the oil leakage is abnormal or not can be sensed in time through the arrangement of the pressure sensing piece 25, a large amount of leakage can be known in time and processed emergently, wherein impurities and discharged oil can be collected through a box body and other structures. The electromagnetic structure 24 does not work normally, and the elastic connection structure 23 keeps the bottom of the oil collecting tank 2 sealed, even if the electromagnetic structure 24 cannot work normally due to a control system problem, the pressure on the filter plate 22 is too large, and the elastic force of the elastic connection structure 23 is not enough to ensure that the oil collecting tank 2 is sealed, so that the open end is automatically opened, and after oil or impurities are removed, the oil or impurities are automatically recovered through the elastic force.
In order to facilitate the installation of the whole detection and recovery system, the connection portion 12 includes an installation cavity 12a and a second permanent magnet 12b embedded therein, specifically, as shown in fig. 5, the second permanent magnet 12b may be an integral structure, or may be intermittently disposed in the installation cavity 12 a. In the process of installation, the installation mode shown in fig. 3 can be obtained by the connection part 12 and the plane outside the speed reducer main body in an adsorption mode; alternatively, the mounting as shown in fig. 4 is obtained by looping the magnetic connection between the two side connections 12. Of course, the structure of the connecting part 12 can be simplified, and a through hole is formed in the connecting part for the connecting part to penetrate through, so that the connecting part can be fixed and installed, and only a proper structure is matched on the speed reducer.
As a preferable example of the above embodiment, as shown in fig. 6, a sealing ring 21a is embedded on a surface of the sealing plate 21, which is attached to the bottom of the tank body, so that sealing is achieved by pressing the sealing ring 21a by the sealing plate 21 and the bottom of the tank body during closing of the open end, where oil is only subjected to gravity unlike a high-pressure environment inside the speed reducer, which is a low-pressure environment, and thus the conventional sealing ring 21a is sufficient to ensure sealing here.
When the filter plate 22 affects the circulation of the oil liquid to the oil tank 3 due to the accumulation of impurities, in order to ensure that the impurities can be smoothly discharged when the open end is open, as shown in fig. 7 to 9, the filter plate 22 is rotatably connected with the sealing plate 21, and the rotating shaft 21b is parallel to the rotating axis of the sealing plate 21 and is close to the open end; the inner wall of the groove is provided with an elastic pull rope 27 connected with the edge of the filter plate 22 for pulling the free end of the filter plate 22 away from the surface of the sealing plate 21 when the sealing plate 21 is opened to a set degree, where the free end is the right end of the filter plate 22 in fig. 7 and 8, i.e. the end relatively far away from the rotating shaft 21 b. In this way, during the process of opening the sealing plate 21, the filter plate 22 forms an angle α as shown in fig. 10 between the sealing plate 21 and the pulling force of the elastic pulling rope 27, and the elastic pulling rope 27 can cause the filter plate 22 to shake to some extent due to the elasticity in the process, so that impurities can be better removed from the open end under the action of a larger inclination angle and shaking, and the cleanness of the filter plate 22 can be ensured. In the preferred embodiment, the pressure-sensitive strip 25 is disposed between the free end side of the filter plate 22, which is not affected by the rotatably mounted side, and the sealing plate 21, and has a better sensitivity. In practice, the pressure-sensitive strip 25 needs to be effectively sealed and the wiring needs to be reasonably distributed and protected from rotation between the filter plate 22 and the sealing plate 21, all of which can be achieved by the prior art.
In order to make the impurities more concentrated during the falling process, the filter plates 22 are respectively provided with baffles 22a at both sides of the length direction of the rotating shaft 21b, and the baffles 22a are arranged perpendicular to the axis of the rotating shaft 21b, as shown in fig. 9, so that the impurities can be limited to be collected along the set direction. Alternatively, for the same purpose, the seal plate 21 is provided with folding fan-shaped seal plates 28 connected to the groove side walls at both side edge positions in the longitudinal direction of the rotary shaft 21b, respectively, so that the directions of impurities and oil can be restricted as well.
As a preference of the above embodiment, the pipeline 31 is provided with a gathering type collecting section 31a from the connection end with the sealing plate 21, so that the oil can be better introduced into the pipeline 31.
Preferably, an annular sealing ring is arranged between the filter plate 22 and the sealing plate 21, and the flow passage on the filter plate 22 covers an annular range, so that oil can be effectively prevented from directly entering the pipeline 31 from a gap between the filter plate 22 and the sealing plate without being filtered, and the probability of damage to a pump body is reduced. In the above preferred scheme, the influence on the work of the pressure sensing piece 25 can be avoided by reasonably controlling the thickness of the sealing ring.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
