Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a petroleum product kinematic viscosity apparatus, includes the viscosimeter 1 of U-shaped structure, and interval certain distance is equipped with first bulb 2 and second bulb 3 on viscosimeter 1's one side pipe wall, and all inlays at the bottom department of first bulb 2 and second bulb 3 and be equipped with response subassembly 4, response subassembly 4 all with the timing device electric connection who corresponds.

The sensing assembly 4 includes a light emitting element 41 and a photosensitive element 42, the light emitting element 41 and the photosensitive element 42 are symmetrically embedded in through holes 43 of the tube walls at the bottom ends of the first ball portion 2 and the second ball portion 3, a first wire holder 44 hermetically matched with the tube walls is disposed at the corresponding tube walls, and the first wire holder 44 is electrically connected with a corresponding timing device through a wire.

The light emitted from the light emitting element 41 is a linear beam, and the beam corresponds to the light receiving element 42.

The light emitting element 41 and the light sensing element 42 are located at the end portions located inside the through hole 43 flush with the inner wall of the viscometer 1.

The viscometer 1 is mainly used for dynamic viscosity detection and motion continuous reading detection in an oil viscosity detection method, the traditional viscometer 1 is only a glass vessel, in the viscosity detection process, when oil reaches the bottom end of the second ball part 3 from the bottom end of the first ball part 2 (hereinafter referred to as a marked line and a b marked line), the oil is usually observed by naked eyes and is timed by a stopwatch, the mode is too coarse, the precision is crossed, the later-stage viscosity measurement is not facilitated, and therefore the induction components 4 are additionally arranged at the a marked line and the b marked line of the viscometer 1.

In the scheme, the light-emitting element 41 emits a light beam to the photosensitive element 42 and is received by the photosensitive element 42, so that a continuous signal is generated, when the oil product flows from the a marked line to the b marked line, because the bottom end of the oil product is arc-shaped (similar to water drops), the oil product firstly flows downwards from the a marked line, when the oil product passes through the a marked line, the arc-shaped surface at the bottom end of the oil product generates light refraction to cause signal interruption, timing is started at the position, and after the oil product continues to flow downwards, the light beam irradiates the photosensitive element 42 at the a marked line again, and the signal is recovered again; when the oil flows to the b marked line, a light ray is refracted firstly to cause signal interruption, timing is ended at the position, the light beam irradiates the photosensitive element 42 at the b marked line again after flowing downwards continuously, the signal is recovered again, the interval of two signal interruptions is the time required by the oil product flowing, and the measured data is more accurate compared with the observation by naked eyes.

Referring to fig. 4-7, in another embodiment, the sensing assembly 4 includes a first contact line 45 and a second contact line 46, opposite ends of the first contact line 45 and the second contact line 46 pass through the closed position of the viscometer 1 and extend into the interior of the viscometer 1, and the ends are partially overlapped, and the other ends of the first contact line 45 and the second contact line 46 are connected to a second wire holder 47 and electrically connected to a corresponding timing device through the second wire holder 47.

The first contact line 45 and the second contact line 46 are both of a memory alloy, and the first contact line 45 and the second contact line 46 are both less than 0.1mm in diameter.

A permanent magnet 48 is embedded at the end part of the second contact wire 46 overlapping with the first contact wire 45, and a stopper 49 is arranged at the outer side of the second contact wire 46 corresponding to the permanent magnet 48.

The resistance heads 49 are uniformly adhered to the surface of the second contact line 46 in a sheet shape, the surface of the resistance heads 49 is coated with an oil-repellent layer, and the minimum distance between the resistance heads 49 is larger than the diameter of the first contact line 45.

In the scheme, the first contact line 45 and the second contact line 46 at the marked line a and the first contact line 45 and the second contact line 46 at the marked line b can be respectively connected with a current sensor, the current sensor detects whether the first contact line 45 and the second contact line 46 are communicated or not to trigger a timing signal, when oil flows downwards from the marked line a, the gravity of the oil can gradually separate the first contact line 45 and the second contact line 46, when the first contact line 45 and the second contact line 46 are separated, the circuit is disconnected, the current sensor cannot detect a current signal, the timing device is triggered to start timing, the same bottom end of the oil flows to the marked line b, the first contact line 45 and the second contact line 46 can be also gradually separated, when the first contact line 45 and the second contact line 46 are separated, the circuit is disconnected, and the current sensor cannot detect the current signal, the timing device is triggered to end timing.

Because the first contact line 45 and the second contact line 46 adopt the memory alloy, the deformation after the bending can be automatically recovered, the contact structure can be used for a long time, and in order to ensure that the superposed part of the first contact line 45 and the second contact line 46 is well contacted, a permanent magnet 48 is embedded at the superposed end part of the second contact line 46 and the first contact line 45, so that the superposed part is tightly contacted.

The first contact line 45 and the second contact line 46 are both small in diameter and have almost no influence on oil, and meanwhile, in order to enable the oil to push the first contact line 45 and the second contact line 46 away, a plurality of resistance heads 49 are arranged at the end part of the second contact line 46 and used for increasing the resistance between the second contact line 46 and the oil, so that the oil can separate the first contact line 45 from the second contact line 46, and the circuit breaking function is realized.
