Description

Technical Field

[0001] This utility model relates to the field of displacement measuring instruments, and in particular to an array-type depth displacement measuring instrument. Background Technology

[0002] Displacement measuring instruments, also known as multi-point displacement gauges, are suitable for long-term installation in hydraulic structures or structures such as earth dams, embankments, slopes, and tunnels. They are mainly used to detect changes in depth, and most of them use an array installation method to ensure the average value of the detection area.

[0003] A search of Chinese patent publication number CN213688274U reveals an array-type depth displacement measuring instrument, comprising a protective assembly, a measuring rod, a sensor, and a wire. The protective assembly includes a protective cover, a sleeve fixedly connected to the top of the protective cover, a guide sleeve connected to the center of the protective cover, a spring disposed on the upper surface of the protective cover, a gasket disposed above the spring, a retaining ring fixedly connected to the top of the gasket, a wire passing through the interior of the guide sleeve, a sensor connected to the bottom of the wire, a measuring rod connected to the bottom of the sensor, a housing disposed outside the measuring rod, and a mounting assembly fixedly connected to the top of the housing.

[0004] Based on the above search results and existing technologies, the following findings were made:

[0005] During the installation process, most existing depth displacement measuring instruments are placed directly into the housing. This process causes the measuring instrument to collide and rub against the housing, which can easily damage the instrument. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes an array-type depth displacement measuring instrument. The rotating shaft drives the threaded rod to rotate through two bevel gears. The rotation of the threaded rod causes the mounting block and the arc plate to move downwards until the measuring instrument body enters the mounting tube. This realizes the lifting of the arc plate, which facilitates the placement of the measuring instrument body into the fixed tube and ensures that the measuring instrument body will not collide with the fixed tube, thus preventing damage to the measuring instrument body.

[0007] The technical solution to achieve the purpose of this utility model is: an array-type depth displacement measuring instrument, including a fixed base, a fixed tube fixedly connected to the upper part of the fixed base, an installation tube fixedly connected to the top of the fixed base, the installation tube and the fixed tube being coaxial, and further comprising;

[0008] A lifting mechanism, which is located on a fixed tube;

[0009] The lifting mechanism includes arc-shaped blocks fixedly connected to the inner walls of the top and bottom ends of a fixed tube. A threaded rod is rotatably connected to both arc-shaped blocks, and a mounting block is screwed onto the threaded rod. An arc-shaped plate is fixedly connected to one side of the mounting block. A rotating shaft is rotatably connected to the mounting tube. A bevel gear is fixedly connected to one end of the rotating shaft and the top end of the threaded rod, and the two bevel gears mesh with each other. A fixing ring is fixedly connected to the top end of the arc-shaped plate, and a measuring instrument body is placed on the fixing ring. A wire is fixedly connected to the top end of the measuring instrument body. Guide rods are fixedly connected to both arc-shaped blocks, and sliders are slidably connected to both guide rods. One end of each slider is fixedly connected to the arc-shaped plate.

[0010] In some embodiments, an L-shaped block is fixedly connected to the fixing ring, a sliding rod is slidably connected to the L-shaped block, a pressure plate is fixedly connected to one end of the sliding rod, and a beveled block is fixedly connected to the other end of the sliding rod.

[0011] In some embodiments, a return spring is sleeved on the sliding rod, and the two ends of the return spring are fixedly connected to the L-shaped block and the inclined block, respectively.

[0012] In some embodiments, a stop block is fixedly connected to the top inner wall of the arc-shaped plate, and the stop block is in contact with the measuring instrument body.

[0013] In some embodiments, the top of the fixing tube has a wire hole that is adapted to a wire.

[0014] In some embodiments, a cover plate is rotatably connected to the mounting tube.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, this utility model uses a lifting mechanism to rotate the rotating shaft, which drives the threaded rod to rotate via two bevel gears. The rotation of the threaded rod causes the mounting block and the arc plate to move downwards until the measuring instrument body enters the mounting tube. This allows the arc plate to be lifted, making it easier to place the measuring instrument body into the fixed tube and ensuring that the measuring instrument body will not collide with the fixed tube, thus preventing damage to the measuring instrument body.

[0017] Secondly, this utility model improves the stability of the measuring instrument body by setting up a pressure plate. When the inclined block comes into contact with the fixed tube, the fixed tube squeezes the inclined block, causing the sliding rod and pressure plate to move towards the stop block until the pressure plate presses down on the measuring instrument body.

[0018] This solves the problem that most existing methods directly place the measuring instrument inside the housing, causing collisions and friction between the measuring instrument and the housing during the insertion process. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] This utility model provides an array-type depth displacement measuring instrument through improvements. The technical solution of this utility model is as follows:

[0028] like Figure 1-Figure 4As shown, an array-type depth displacement measuring instrument includes a fixed base 1, a fixed tube 11 fixedly connected to the fixed base 1, and an installation tube 2 fixedly connected to the top of the fixed base 1. The installation tube 2 and the fixed tube 11 are coaxial. The instrument also includes a lifting mechanism located on the fixed tube 11. The lifting mechanism includes arc-shaped blocks 12 fixedly connected to the inner walls of the top and bottom ends of the fixed tube 11. The arc-shaped blocks 12 are welded to the fixed tube 11 to improve their stability. A threaded rod 17 is rotatably connected to both arc-shaped blocks 12. An installation block 16 is screwed onto the threaded rod 17. An arc-shaped plate 15 is fixedly connected to one side of the installation block 16. A rotating shaft 21 is rotatably connected to the installation tube 2. A bevel gear 22 is fixedly connected to one end of the rotating shaft 21 and the top end of the threaded rod 17. The two bevel gears 22 mesh with each other. The top end of the arc-shaped plate 15 is fixed... A fixing ring 3 is connected, and to make the fixing ring 3 more secure, the fixing ring 3 is fixed to the fixing ring 3 by welding. The measuring instrument body 4 is placed on the fixing ring 3. The top of the measuring instrument body 4 is fixedly connected to the wire 41. The two arc blocks 12 are jointly fixedly connected to the guide rod 13. The two guide rods 13 are slidably connected to the sliders 14. One end of the two sliders 14 is fixedly connected to the arc plate 15. Through the setting of the lifting mechanism, the rotating shaft 21 drives the threaded rod 17 to rotate through the two bevel gears 22. The rotation of the threaded rod 17 drives the mounting block 16 and the arc plate 15 to move downward until the measuring instrument body 4 enters the mounting tube 2, thereby lifting the arc plate 15, so as to facilitate the placement of the measuring instrument body 4 into the fixing tube 11, ensuring that the measuring instrument body 4 will not collide with the fixing tube 11 and thus preventing damage to the measuring instrument body 4.

[0029] like Figure 3 As shown, in one embodiment, to make the L-shaped block 31 more secure, the L-shaped block 31 is fixed to the fixing ring 3 by welding. The fixing ring 3 is fixedly connected to the L-shaped block 31, and a sliding rod 32 is slidably connected to the L-shaped block 31. One end of the sliding rod 32 is fixedly connected to a pressure plate 33, and the other end of the sliding rod 32 is fixedly connected to a beveled block 34. With the setting of the pressure plate 33, when the beveled block 34 contacts the fixing tube 11, the fixing tube 11 squeezes the beveled block 34, causing the sliding rod 32 and the pressure plate 33 to move towards the stop block 18 until the pressure plate 33 presses down on the measuring instrument body 4, thereby improving the stability of the measuring instrument body 4.

[0030] like Figure 3 As shown, in one embodiment, a return spring 35 is sleeved on the sliding rod 32, and the two ends of the return spring 35 are fixedly connected to the L-shaped block 31 and the inclined block 34 respectively; by setting the return spring 35, when the inclined block 34 moves away from the fixed tube 11, the return spring 35 drives the sliding rod 32 and the pressure plate 33 to reset.

[0031] like Figure 3As shown, in one embodiment, the stop 18 is made of metal, and the stop 18 is fixedly connected to the top inner wall of the arc plate 15. The stop 18 is in contact with the measuring instrument body 4. Through the setting of the stop 18, the stop 18 and the pressure plate 33 cooperate to fix the measuring instrument body 4.

[0032] like Figure 2 As shown, in one embodiment, the top of the fixing tube 11 is provided with a wire hole 23, which is adapted to the wire 41; the wire hole 23 facilitates the placement of the wire 41.

[0033] like Figure 1 As shown, in one embodiment, a cover plate 24 is rotatably connected to the mounting tube 2; the mounting tube 2 is covered by the cover plate 24.

[0034] The specific working method is as follows: When in use, the measuring instrument body 4 is placed on the fixed ring 3. The rotating shaft 21 drives the threaded rod 17 to rotate through the two bevel gears 22. The rotation of the threaded rod 17 drives the mounting block 16 and the arc plate 15 to move downward. The movement of the arc plate 15 drives the fixed ring 3 and the measuring instrument body 4 to move downward. At the same time, the arc plate 15 drives the L-shaped block 31, the sliding rod 32, the pressure plate 33 and the inclined block 34 to move. When the inclined block 34 contacts the fixed tube 11, the fixed tube 11 squeezes the inclined block 34, which drives the sliding rod 32 and the pressure plate 33 to move towards the stop block 18 until the pressure plate 33 presses down on the measuring instrument body 4, which improves the stability of the measuring instrument body 4. Then the measuring instrument body 4 continues to move downward until it enters the mounting tube 2, which raises the arc plate 15, making it easier to put the measuring instrument body 4 into the fixed tube 11 and ensuring that the measuring instrument body 4 will not collide with the fixed tube 11, so that the measuring instrument body 4 will not be damaged.

Matters not covered in this utility model are common knowledge to those skilled in the art.
