Measurement Object 28.

The electronic deflection meter comprises a composite housing 1, a pulley 4 and a cable 15. A displacement meter 6, a power source 25, and a recording device 18 are located in the composite housing 1.

The composite housing 1 is made with front 2 and rear 3 walls.

The pulley 4 is placed on the side of the rear wall 3 of the composite housing 1.

The cable 15 is rigidly connected to the pulley 4 at one end, a hook 17 is made at its other end for attachment to the measurement object 28.

Coaxially to the pulley 4, a protective cover 5 is installed, having an opening 16 for the cable 15. The protective cover 5 is mounted on the composite housing 1.

The displacement meter is made in the form of a photoelectric transducer of angle 6 with emitters 7, an indicator disk 8, and photodetectors 9 mounted stationary. The movable part of the angle photoelectric transducer 6 contains a rotary axis of rotation 13. A rotary axis of rotation 13 is mounted in the bearings 14. A holder 11 is fixed at one end of the rotary axis of rotation 13. The holder 11 is mounted coaxially to the bearings 14. The measuring disk 10 is rigidly fixed to the holder 11.

Between the pulley 4 and the composite housing 1, a spiral flat spring 12 is installed. The spiral flat spring 12 is fixed at one end to the rotary axis of rotation 13 and the other end to the composite housing 1. The plane of the spiral flat spring 12 is perpendicular to the rotary axis of rotation 13.

The recording device 18 contains a unit for transmitting measurement information on the radio channel 24 and is made in the form of a processing board 19 with a display 20. The processing board 19 contains a button 23 for controlling the "memory" function, which is located on the front wall 2. Buttons for controlling the "on" functions "shutdown" 21 combined. The control buttons for the “on” - “off” 21 and “zeroing” 22 functions are also located on the front wall 2 of the composite housing 1. The processing board 19 is electrically connected to the angle photoelectric transducer 6, a power source 25, a communication connector with a computer 27, a connection connector in an external power source 26 and an information transmission unit via radio channel 24.

The power source 25 can be made in the form of a standalone battery, for example, a battery, battery, etc. The power supply of the electronic deflection meter is carried out from the power source 25. The power supply of the electronic deflection meter can be carried out through the connector 26 from an external power source through an adapter (not shown) from the AC mains.

The electronic deflection meter measures as follows.

The composite body 1 of the electronic deflection meter is fixed motionless relative to the measurement object 28. The end of the cable 15 is secured to the measurement object 28 by means of the hook 17. The electronic deflection meter is controlled by successively pressing the control buttons on-off-21, zeroing 22 and “memory” 23, which stores the measurement result or refuses to store the measurement result when pressed again. With this tension

the cable 15 when securing it to the measurement object 28 is provided by a spiral flat spring 12.

With the deflection of the measurement object 28, the position of the end of the cable 15 fixed on the measurement object 28 changes — it is wound on the pulley 4, and this leads to the angular movement of the pulley 4 together with the rotary axis of rotation 13. In turn, the angular movement of the axis of rotation 13 leads to the rotation of the measuring disk 10 in the composite housing 1. The luminous flux from the emitters 7, passing through the measuring disk 10 and the indicator disk 8, goes to the photodetectors 9 and then to the processing board 19. Thus, for each value of the rotation angle of the rotary axis of rotation I 13 with a measuring disk 10 has its own combination of electrical signals coming from photodetectors 9. An analog signal from photodetectors 9 is fed to the recording device 18, recorded and processed by it, while the magnitude of the deflection is displayed on the display 20 of the processing board 19 with signs indicating the direction of deflection . Information about the magnitude of the deflection of the measurement object 28 can also be transmitted through the communication connector 27 to a personal computer (not shown) or through a unit for transmitting information via radio channel 24 to a user receiver (not shown).

Equipping the electronic deflection meter with a radio channel for transmitting information will allow you to remotely transmit measurement information to a user who may be outside the visibility of the measurement object, this increases safety when measuring bends of heavy building structures in earthquake-prone areas, simplifies measurement and extends the operational capabilities of the electronic deflection meter.

Providing an electronic deflection meter with a spiral flat spring fixed at one end on the rotary axis of rotation, and the other end on the body, and fixing one end of the cable to the pulley, which ensures constant cable tension when fixing it to the measurement object, which simplifies the measurement and operation process itself.

In addition, fixing the other end of the cable to the pulley and the connection of the axis of rotation with the housing by means of a spiral flat spring ensures the cable is wound on the pulley, both during measurements and after they are completed, when the hook is detached from the measurement object, this ensures the placement of the cable in the amount of dimensions electronic deflection meter, which is especially convenient when transporting it.

Placing a spiral flat spring between the pulley and the housing, so that the plane of arrangement of the spiral flat spring (plane of maximum compliance) is perpendicular to the rotary axis of rotation, increases the compact design of the electronic deflection meter.

The implementation of the hook at one end of the cable provides the convenience of connecting the electronic deflection meter with the measurement object and simplifies the measurement.

The supply of the deflection meter with a cover with a hole for the cable provides protection of its rotating part and from the ingress of foreign objects, which increases the safety of work and extends the operational capabilities.

Placing the protective cover coaxially to the pulley and fixing it to the composite case contribute to the creation of a compact design of the electronic deflection meter.

The combination of the control buttons for the “on” and “off” functions provides a simplification of the design, and the introduction of the “memory” function control buttons on the processing board provides, if necessary, storing of the measurement result, which extends the operational capabilities of the electronic deflection meter. The location of the control buttons of the "memory" function on the front wall of the housing, together with other control buttons, provides the convenience of controlling the electronic deflection meter.

The proposed deflection meter is manufactured industrially by NPF Zavod Zavod Zonon LLC, which is confirmed by the tests of an experimental batch, and this, according to the applicant, determines its compliance with the criterion of “industrial applicability”.
