[0002] Currently, optoelectronic measurement technology refers to the technology that uses optical fiber communication and optoelectronic devices to measure and transmit various physical quantities at high potentials. Since the optoelectronic measurement system uses non-conductive optical fibers to transmit information, it can be conveniently used in occasions with extremely high voltages. It has high sensitivity, light weight, small size, and strong anti-electromagnetic interference, and can measure a wide variety of physical quantities.

[0003] In related technologies, the optoelectronic measuring instrument emits light, and the light irradiates certain substances, causing changes in the electrical properties of the substances. This phenomenon is called the photoelectric effect. In order to enable the optoelectronic measuring instrument to project light onto substances more conveniently, the bottom of the optoelectronic measuring instrument is set to be liftable, so as to more conveniently adjust the position of the optoelectronic measuring instrument; and when using the optoelectronic measuring instrument, it is usually necessary to adjust the balance of the entire optoelectronic measuring instrument to ensure the levelness of the optoelectronic measuring instrument, thereby improving the measurement accuracy.

Detailed implementation manners

[0028] The following further describes the present application in detail with reference to the attached Figure 1 - Figure 6 drawings.

[0029] An embodiment of the present application discloses an optoelectronic measuring instrument.

[0030] Embodiment 1 Refer to Figure 1 And Figure 2, An optoelectronic measuring instrument, including a frame 11, an optoelectronic detector 1 and a bubble level 10 are installed on the frame 11. Four legs 5 are provided at the bottom of the frame 11. A lifting rod 8 is connected in a lifting manner inside the leg 5. A threaded strip 18 is integrally formed on the outer wall of the lifting rod 8. A driving member 6 for driving the lifting rod 8 to lift is installed at the bottom of the frame 11. The driving member 6 is a driving motor. A gear 16 is rotatably connected to the driving motor. The gear 16 is meshed with the threaded strip 18 to achieve the purpose of controlling the vertical movement of the lifting rod 8. A bubble sensor 9 for sensing the position of the bubble is installed on the frame 11. The bubble sensor 9 is an infrared sensor. The bubble sensor 9 is electrically connected to the driving member 6. When the bubble sensor 9 detects that the bubble deviates to one side, the bubble sensor 9 controls the driving member 6 on the opposite side of the bubble to drive the lifting rod 8 to descend, so that the lower side of the frame 11 can be lifted. A control valve 4 for controlling the start of the four driving members 6 is installed on the frame 11. The control valve 4 controls the synchronous descent of the multiple lifting rods 8, so that the frame 11 can rise more stably, improving the convenience of adjusting the optoelectronic detector 1. The lifting rod 8 is used to complete the horizontal adjustment and height adjustment synchronously, which can greatly reduce the overall complexity of the instrument, reduce the number of components, and reduce the overall weight of the instrument, improving the simplicity of using the instrument. By adjusting the level first and then the height, the center of gravity can be close to the middle position, improving the stability of the instrument during use.

[0031] Refer to Figure 3 and Figure 4 , A support seat 27 is fixed at the bottom of the lifting rod 8. A rotating wheel 7 is rotatably connected to the support seat 27. The use of multiple rotating wheels 7 can make the frame 11 move more conveniently, improving the convenience of using the frame 11. The bottom of the lifting rod 8 is rotatably connected to a locking plate 12. A limiting arc piece 14 for pressing the rotating wheel 7 is fixed on one side of the locking plate 12 close to the rotating wheel 7. A brake pad 15 is arranged on one side of the limiting arc piece 14 close to the rotating wheel 7. The brake pad 15 is made of rubber material. A pressing spring 13 for driving the limiting arc piece 14 to abut against the rotating wheel 7 is fixed on the locking plate 12. Through the cooperation of the pressing spring 13 and the limiting arc piece 14, the rotating wheel 7 can be locked more stably. An unlocking plate 17 that abuts against the locking plate 12 is fixed on the side wall of the leg 5. When the lifting rod 8 is retracted into the leg 5, the locking plate 12 supports the unlocking plate 17 and drives the limiting arc piece 14 away from the rotating wheel 7. Thus, the rotating wheel 7 can be unlocked, making the frame 11 move more conveniently. After the lifting rod 8 moves downward, the limiting of the rotating wheel 7 is realized, and at the same time, the leveling, heightening and locking of the position are realized, making the instrument more intelligent to use, improving the convenience and stability of using the instrument.

[0032] Refer to Figure 1 and Figure 2, a sliding seat 3 is horizontally slidably connected to the frame 11, the photoelectric detector 1 is installed on the sliding seat 3, and a power member 2 for driving the sliding seat 3 to move horizontally is fixed on the frame 11. The power member 2 is a cylinder. By driving the cylinder, the photoelectric detector 1 can be more accurately aligned with the substance to be detected. An installation hole is formed through the bottom of the sliding seat 3, and a cooling fan 28 is installed in the installation hole. The cooling fan 28 cools the photoelectric detector 1 to improve the use effect of the photoelectric detector 1.

[0033] The implementation principle of an optoelectronic measuring instrument according to an embodiment of the present application is as follows: During operation, the frame 11 is placed on the detection site. Under the action of the bubble inductor 9, the position of the bubble in the bubble level 10 is detected, and in cooperation with the driving member 6, the position of each driving member 6 can be adjusted to adjust the frame 11 and improve the adjustment effect of the frame 11. Further, in cooperation with the control valve 4, under the action of multiple driving members 6, the four lifting rods 8 can be synchronously lowered, so that the frame 11 can be horizontally lifted. With such a design, the horizontal adjustment and height adjustment of the frame 11 can use the same device, thereby greatly reducing the overall complexity of the structure of the frame 11. By adjusting the height of the frame 11 through multiple driving rods, the frame 11 can be leveled as a whole. After adjusting the height, the center of gravity of the instrument is closer to the center position, improving the overall stability of the instrument.

[0034] Embodiment 2 Refer to Figure 5 and Figure 6 , the difference between this embodiment and Embodiment 1 is that a protective cover 19 is rotatably connected to the frame 11. The protective cover 19 shields the photoelectric detector 1 and the bubble level 10 to prevent dust from entering and reduce damage to the photoelectric detector 1, ensuring the use effect of the instrument; both ends of the protective cover 19 are fixed with connecting plates 22. The connecting plates 22 are rectangular plates and are rotatably connected to the frame 11. The lifting rods 8 penetrate through the frame 11. A limiting arc groove 23 is formed on one side of the connecting plate 22 close to the lifting rod 8. The limiting arc groove 23 is in a C shape. The top of the lifting rod 8 abuts against the limiting arc groove 23. When the lifting rod 8 is retracted, the lifting rod 8 supports the protective cover 19 to close the frame 11; A connecting spring 29 for driving the protective cover 19 to open is connected between the frame 11 and the connecting plate 22. During operation, when the lifting rod 8 descends, under the action of the connecting spring 29, the protective cover 19 can be driven to open the photoelectric detector 1 and the bubble level 10, making the photoelectric detector 1 and the bubble level 10 more convenient to use and improving the convenience of using the optoelectronic measuring instrument.

[0035] A support wheel 24 is rotatably connected to the top of the lifting rod 8, and the support wheel 24 abuts against the limit arc groove 23 to improve the smoothness of the closing of the protective cover 19. The protective cover 19 is composed of a plurality of protective plates 30 hinged together. A storage seat 20 slidably matched with the protective plate 30 is fixed on the side wall of the frame 11. The cooperation with the storage seat 20 enables the protective cover 19 to be recycled more conveniently. A sealing strip 26 is fixed between adjacent protective plates 30, and the sealing strip 26 is made of rubber material. Guide plates 21 are arranged on both sides of the protective cover 19 on the frame 11. The guide plates 21 are fan-shaped. Both sides of the protective cover 19 are slidably connected to the guide plates 21, and under the action of the guide plates 21, the plurality of protective plates 30 slide stably and smoothly.

[0036] The implementation principle of Embodiment 2 is as follows: During operation, through the cooperation of the lifting rod 8 and the limit arc groove 23, the protective cover 19 can be opened and closed more conveniently for the photoelectric detector 1. The lifting rod 8 can meet the requirements of lifting and leveling, and can also realize the opening and closing of the protective cover 19, improving the convenience of using the instrument. With such a design, by using the lifting rod 8, multiple function operations can be completed simultaneously, reducing dust from falling on the photoelectric detector 1 and the bubble level 10, and reducing the collision with the photoelectric detector 1 and the bubble level 10, improving the safety of using the photoelectric measuring instrument.

[0037] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
