Description

Technical Field

[0001] The invention relates to the technical field of water conservancy measurement, in particular to an inclinometer for monitoring water conservancy buildings. Background Art

[0002] During the foundation construction of water conservancy structures (such as dams), inclinometers are often needed to monitor settlement to ensure construction safety.

[0003] The basic configuration of an inclinometer includes an inclinometer tube, an inclinometer probe, a control cable, and an inclinometer readout. In actual operation, the inclinometer tube is usually pre-installed during the pouring of the building. During the inspection, the personnel arrive at the designated inclinometer tube, connect the cable with the inclinometer probe and the inclinometer readout, and then place the inclinometer probe into the inclinometer tube. Then, by gradually pulling up the cable, the readout is used to determine whether the building's inclination meets the standard.

[0004] During the inspection process, the guide wheel on the inclinometer probe mates with the groove on the inclinometer tube to control the downward movement of the inclinometer tube. However, to increase measurement speed, the wheelbase must be increased and the number of measurement points reduced. However, traditional inclinometers are generally designed with a one-piece structure, and their wheelbase is fixed at the factory, making subsequent adjustment impossible. When measuring with a large wheelbase, users often have to purchase a custom inclinometer that meets the requirements. This not only prolongs the procurement cycle but also increases costs. Furthermore, for some practical applications where the wheelbase changes frequently, users have to purchase multiple inclinometers with different wheelbase specifications to meet different measurement requirements. This not only makes carrying and storing these devices extremely inconvenient, but also significantly increases procurement and maintenance costs. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 3 The inclinometer for monitoring water conservancy structures shown in the figure includes an inclinometer probe 1, which is inserted into the inclinometer tube for inclinometer operation; it also includes: a rotating chamber 2 provided on the inclinometer probe 1, a rotating seat 3 is rotatably connected in the rotating chamber 2, guide wheels 4 are symmetrically provided on both sides of the rotating seat 3, an adjustment unit 5 is provided between the two guide wheels 4, the adjustment unit 5 is connected to one end of the guide wheel 4 and is used to adjust the wheelbase between the two guide wheels 4; and a limiting tube 6 fixedly connected to the front and rear sides of the rotating seat 3, an arc-shaped groove 7 adapted to the limiting tube 6 is opened on the outer wall of the inclinometer probe 1, an oil box 8 is fixed on the top of the rotating seat 3, a smearing unit 9 is provided between the oil box 8 and the guide wheel 4, and the input end of the smearing unit 9 is transmission-connected to a transmission assembly 10, which drives the smearing unit 9 to lubricate the guide wheel 4;

[0032] In this solution, during actual operation, the inclinometer probe 1 will be placed in the inclinometer tube for inclinometer operation. At this time, the two guide wheels 4 will be distributed in a high and low position, and will roll along the inner wall groove of the inclinometer tube during the process of inserting the inclinometer probe 1. However, the wheelbase between the two existing high and low guide wheels 4 is fixed, so the extreme state of the two guide wheels 4 in the high and low distribution can only adapt to the inclinometer tube of a specified inner diameter. In this case, the wheelbase between the two guide wheels 4 can be manually adjusted by using the adjustment unit 5 between the two guide wheels 4. In this way, when the two guide wheels 4 are distributed in a high and low position, the wheelbase will change to meet the measurement requirements of a larger inclinometer tube inner diameter. That is, the two guide wheels 4 can roll more flexibly in inclinometer tubes of different specifications, thereby meeting the needs of different measurement scenarios, improving the applicability and flexibility of the inclinometer, and eliminating the need to purchase multiple inclinometers with different wheelbase specifications, thereby reducing usage costs and maintenance difficulties.

[0033] When the adjustment unit 5 is being adjusted, the transmission component 10 can also drive the coating unit 9 to work, so that the lubricating oil in the oil box 8 can be accurately dripped into the bearing of the guide wheel 4, thereby achieving synchronous lubrication of the guide wheel 4 and improving the service life of the guide wheel 4.

[0034] For further information, see Figure 4 The adjusting unit 5 includes a bidirectional stud 11 rotatably mounted inside the rotating seat 3, and both ends of the bidirectional stud 11 are threadedly connected to an adjusting block 12, and the adjusting block 12 is slidably sleeved with the rotating seat 3. The middle part of the bidirectional stud 11 is transmission-connected with a driving member 13, and one end of the adjusting block 12 is fixed with a U-shaped seat 14, and the guide wheel 4 is rotatably connected to the U-shaped seat 14 through a bearing;

[0035] It should be noted that when the guide wheel 4 without wheelbase adjustment is placed in the inclinometer tube with a larger inner diameter, the two guide wheels 4 in the high and low states cannot slide normally in the corresponding grooves. During the adjustment process, the inclinometer probe 1 is first placed in the inclinometer tube normally, and then the two guide wheels 4 are in the extreme state of one high and one low. In this state, the operator can forcefully push one guide wheel 4 upward, and then manually operate the driving member 13. The driving action of the driving member 13 will drive the two-way stud 11 to rotate, and then drive the two adjustment blocks 12 to move away from each other until the edges of the two guide wheels 4 are again in contact with the inclinometer tube with a larger inner diameter. The wheelbase adjustment of the two bottom guide wheels 4 is completed, and the inclinometer probe 1 is then continued to be placed until the two top guide wheels 4 are about to enter the inclinometer tube. The same operation is then performed to make the two top guide wheels 4 normally fit with the grooves of the inclinometer tube. In this way, the wheelbase adjustment of the guide wheels 4 is completed, and finally the inclinometer operation is carried out.

[0036] For further information, see Figure 5 The driving member 13 includes a worm wheel 15 fixedly sleeved on the middle part of the bidirectional stud 11, a worm 16 is meshed on the upper side of the worm wheel 15, and a rotating shaft 17 is fixed at both ends of the worm 16. The rotating shaft 17 is rotatably connected to the limiting tube 6 through a bearing, and an operating handle 18 is fixed to the outer end of the rotating shaft 17;

[0037] Specifically, during operation, the operator manually rotates the operating handle 18, so that the operating handle 18 drives the rotating shaft 17 to rotate, and the rotating shaft 17 will rotate relatively in the limiting tube 6, thereby driving the worm 16 to rotate, and the worm 16 then drives the worm wheel 15 to rotate, so that the worm wheel 15 drives the two-way stud 11 to rotate, thereby realizing the mutual movement of the two adjustment blocks 12. The design of the worm wheel 15 and the worm 16 is adopted here, so that the worm 16 has a self-locking function when driving the worm wheel 15 to rotate, that is, when the operator stops rotating the operating handle 18, the worm wheel 15 and the worm 16 will not be reversed due to external force, thereby ensuring the stability of the guide wheel 4 after the wheelbase is adjusted, avoiding the displacement of the guide wheel 4 during the inclination measurement process, and improving the accuracy and reliability of the inclination measurement.

[0038] It should be noted that: See Figure 3In this solution, rubber springs 38 are fixed to the outer walls of both sides of the limiting tube 6. One end of the rubber spring 38 away from the limiting tube 6 is fixed to the bottom of the arc groove 7. When the limiting tube 6 rotates in the arc groove 7, the two sides of the limiting tube 6 will stretch and compress the rubber springs 38. In this way, when the guide wheel 4 hits the protrusion in the groove of the inclinometer tube, it will drive the limiting tube 6 to rotate slightly, so that the rubber spring 38 absorbs the micro-rotation and causes vibration, effectively reducing the hard collision between the guide wheel 4 and the inclinometer tube, avoiding damage to the guide wheel 4 and the inclinometer tube due to collision, and improving the service life of the inclinometer. The elastic action of the rubber spring 38 can make the limiting tube 6 quickly reset after being subjected to external force, maintain the stability of the wheelbase of the guide wheel 4, and further ensure the accuracy of inclinometer measurement.

[0039] For further information, see Figure 10 A scraper 40 is fixed to the inner wall of the U-shaped seat 14, and a friction surface is provided on one side of the scraper 40. The outer wall of the guide wheel 4 fits with the friction surface and is used to clean the dirt adsorbed on the outer wall of the guide wheel 4, thereby avoiding the accumulation of dirt affecting the rotation effect of the guide wheel 4 and the accuracy of inclination measurement. The material of the friction surface is preferably a wear-resistant material with a certain elasticity, such as rubber or polyurethane. Such a material can not only ensure a close fit with the outer wall of the guide wheel 4, but also reduce the wear of the guide wheel 4 during the cleaning process.

[0040] In this solution, the process of measuring the building inclination includes the following steps:

[0041] In the first step, personnel carry the inclinometer probe 1, control cable, inclinometer reading instrument and other equipment to the pre-buried inclinometer pipe of the building, and then assemble the inclinometer probe 1, control cable and inclinometer reading instrument in sequence;

[0042] In the second step, first extend the two guide wheels 4 at the bottom of the inclinometer probe 1 into the inclinometer tube. When the inner diameter of the inclinometer tube is larger than the wheelbase of the guide wheels 4, adjust the wheelbase using the adjustment unit 5 until the edges of the two guide wheels 4 fit into the inclinometer tube. Then continue to insert the inclinometer probe 1 until the two top guide wheels 4 are about to enter the inclinometer tube. Then, perform the same operation again until the two top guide wheels 4 fit into the grooves of the inclinometer tube properly.

[0043] In the third step, the personnel continue to slowly place the inclinometer probe 1 into the inclinometer tube, and obtain the building inclination data by combining the data from the inclinometer reading instrument;

[0044] In the fourth step, personnel need to test the same inclinometer tube on both sides in different directions. At this time, the inclinometer tube probe is rotated 90° and inserted into the inclinometer tube again for measurement.

[0045] Example 2: Please refer to Figure 6 - Figure 8This embodiment further explains the first embodiment, and the difference lies in that the performance of the guide wheel 4 is optimized.

[0046] Specifically, the smear unit 9 includes a fixing frame 19 fixedly connected to the outer wall of the rotating seat 3, a support block 20 is fixed to the end of the fixing frame 19 away from the rotating seat 3, a sealing cylinder 21 is fixedly sleeved in the support block 20, a piston block 22 is slidably connected in the sealing cylinder 21, an oil inlet pipe 23 is connected between the sealing cylinder 21 and the oil box 8, an smearing tube 24 is fixedly inserted into the outer side of the U-shaped seat 14, one end of the smearing tube 24 is connected to the bearing portion of the U-shaped seat 14 for mounting the guide wheel 4, an oil outlet pipe 25 is connected between the smearing tube 24 and the sealing cylinder 21, and the output end of the transmission assembly 10 is rotatably connected to the piston block 22;

[0047] Among them, the transmission assembly 10 includes a rack 26 fixedly connected to the outer wall of the U-shaped seat 14, and a transmission gear 27 is meshed on the rack 26. One end of the wheel axle of the transmission gear 27 is rotatably connected to a support plate 28, and the bottom end of the support plate 28 is fixed to the fixed frame 19. The outer side of the wheel axle of the transmission gear 27 is also fixedly sleeved with a driving pulley 29, one end of the piston block 22 is rotatably connected to a connecting rod 30, and the end of the connecting rod 30 away from the piston block 22 is hinged with a crank 31, one end of the crank 31 is fixedly sleeved with a transmission shaft 32, and one end of the transmission shaft 32 is fixed with a driven pulley 34, and a synchronous belt 33 is connected between the driving pulley 29 and the driven pulley 34. The outer side of the transmission shaft 32 is also rotatably connected to an L-shaped plate 35, and one end of the L-shaped plate 35 is fixed to the outer wall of the rotating seat 3.

[0048] In this solution, when the adjusting block 12 drives the U-shaped seat 14 to move, it will also drive the rack 26 to move, and the rack 26 drives the transmission gear 27 to rotate. The transmission gear 27 and the active pulley 29 rotate coaxially together, and the active pulley 29 drives the driven pulley 34 to rotate, and the driven pulley 34 drives the crank 31 to rotate, so that the crank 31 drives the piston block 22 through the connecting rod 30 to complete a left and right reciprocating movement in the sealing cylinder 21, and then a small amount of lubricating oil in the oil box 8 is discharged into the oil outlet pipe 25 through the oil inlet pipe 23 and the sealing cylinder 21, and finally accurately dripped into the wheel shaft bearing of the guide wheel 4 through the smearing capillary 24, thereby realizing synchronous lubrication of the guide wheel 4 and improving the service life of the guide wheel 4. At the same time, the entire lubrication process has a high degree of automation, and there is no need for frequent manual addition of lubricating oil, which reduces maintenance costs and also improves the working efficiency and reliability of the inclinometer for monitoring water conservancy buildings.

[0049] It should also be noted that the synchronous rotation of the driving pulley 29 and the driven pulley 34 ensures smooth and continuous reciprocating motion of the piston block 22 within the sealing cylinder 21, avoiding the problem of uneven lubricating oil dripping caused by unstable motion. In addition, the design of the applicator tube 24 allows the lubricating oil to drip accurately into the wheel axle bearing, avoiding lubricating oil waste and improving lubrication efficiency.

[0050] It should also be noted that an oil inlet check valve 36 is provided at the connection point between the oil inlet pipe 23 and the sealing cylinder 21, and an oil outlet check valve 37 is provided at the connection point between the oil outlet pipe 25 and the sealing cylinder 21. This ensures that the lubricating oil can only flow in one direction when the oil inlet pipe 23 enters the sealing cylinder 21, avoiding waste or pollution caused by backflow. Similarly, when the piston block 22 pushes the lubricating oil from the sealing cylinder 21 into the oil outlet pipe 25, the oil outlet check valve 37 can also ensure that the lubricating oil flows out in one direction, thereby ensuring a stable supply of lubricating oil.

[0051] Example 3: Please refer to Figure 4 and Figure 9 This embodiment further explains other embodiments, and the difference lies in that the maintenance and replacement steps of the guide wheel 4 are optimized.

[0052] Specifically, the adjustment unit 5 includes a bidirectional stud 11 rotatably installed inside the rotating seat 3, and both ends of the bidirectional stud 11 are threadedly connected to an adjustment block 12. The adjustment block 12 is slidably connected to the rotating seat 3, and the middle part of the bidirectional stud 11 is transmission-connected with a driving member 13. A U-shaped seat 14 is fixed to one end of the adjustment block 12, and the guide wheel 4 is rotatably connected to the U-shaped seat 14 through a bearing; a screw hole 39 is provided on the inner side of the adjustment block 12 to cooperate with the bidirectional stud 11, and the depth of the screw hole 39 is less than the length of the adjustment block 12.

[0053] It should be noted that in this embodiment, once the two adjustment blocks 12 are detached from the ends of the bidirectional stud 11, the guide wheel 4 can be easily removed from the rotating seat 3 without the need for other tools, greatly improving the efficiency of guide wheel 4 maintenance and replacement. In addition, the bidirectional stud 11 and adjustment blocks 12 in this embodiment have a simple structure and are easy to manufacture and install, reducing the manufacturing cost and maintenance difficulty of the guide wheel 4.

[0054] It should also be noted that after removing the adjustment block 12, the applicator tube 24 on the U-shaped seat 14 is also pulled out so that the applicator tube 24 can be cleaned or replaced later to ensure that it can smoothly drip lubricating oil into the bearing part of the guide wheel 4 when used next time. At the same time, if the applicator tube 24 has problems such as wear or blockage, a new applicator tube 24 can be replaced in time to ensure the normal operation of the lubrication operation and measurement accuracy.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
