Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy project construction, and in particular is an inclination detection device for water conservancy gate construction. Background Art

[0002] As an important infrastructure related to people's livelihood, water conservancy projects undertake multiple key functions such as flood control, irrigation, water supply, shipping, power generation, etc. Among them, water conservancy gates are the core components of water conservancy hubs to accurately control water flow and water level and ensure the safe and efficient operation of water conservancy facilities, and the inclination is the monitoring indicator of the gates.

[0003] For example, the invention with publication number CN113639713B relates to an inclination detection device for water conservancy gate construction. When the detection plate is placed on the surface of the water conservancy gate for detection, the inclination change of the water conservancy gate can be checked through the scale line and the pointer on the swing arm. However, since the detection plate needs to be placed on the surface of the water conservancy gate, according to the values ​​fed back by the pressure sensors on both sides of the swing arm, when the values ​​of the left and right pressure sensors are the same, it is judged that there is no pressure difference between the left and right sides and whether the device is placed flat. Only then can the gate be detected for inclination.

[0004] However, after the gate is installed, the operator places the detection device on the gate surface and keeps it there to detect the local inclination of the gate. For gates in the same vertical direction, the operation requires multiple measurements and records to fully measure the inclination data of the gate in the same vertical direction, and the operator also needs to pay attention to the correlation of each measurement data to better judge the overall inclination of the gate, which is time-consuming and laborious and will also reduce the measurement accuracy.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 11 As shown, the present invention provides an inclination detection device for water conservancy gate construction, including a dam body 2 and a gate 1, and also includes: a bracket assembly 3, which is arranged on one side of the gate 1; a fixing assembly 4, which is arranged on the bracket assembly 3 and used to fix the bracket assembly 3 on the dam body 2; a detection mechanism 5, which is installed on the bracket assembly 3;

[0038] The bracket assembly 3 includes a connecting frame 31, and a connecting rod 1 33 is hinged at both ends of the connecting frame 31. A connecting rod 2 34 is movably sleeved outside the connecting rod 1 33. Elastic bayonet pins 32 that can be inserted into the connecting rod 1 33 are elastically supported at both ends of the connecting frame 31. When the elastic bayonet pins 32 are inserted into the connecting rod 1 33, the connecting rod 2 34, the connecting rod 1 33 and the connecting frame 31 are in the same straight line. A spiral groove 341 is provided at one end of the connecting frame 31.

[0039] The fixing assembly 4 includes a spline shaft 41 movably connected to one end of the second connecting rod 34, a worm wheel 42 is movably connected to the outside of the spline shaft 41, and a worm 44 meshing with the worm wheel 42 is also movably connected to one end of the second connecting rod 34. One end of the worm wheel 42 extends to the outside of the second connecting rod 34 and is connected to a limiting column 43 by a bearing. A convex shaft 411 that can slide in the spiral groove 341 is also fixedly connected to the spline shaft 41;

[0040] The detection mechanism 5 includes a mounting frame 51 movably mounted on the outside of the connecting frame 31 or the connecting rod 34, a screw combination gasket 52 is threadedly connected to the top of the mounting frame 51, a cross frame 54 penetrating the mounting frame 51 is movably connected to the bottom of the mounting frame 51, an end of the cross frame 54 close to the gate 1 is movably connected to a roller 56, a tension spring combination rod 53 is elastically connected to the bottom of the mounting frame 51, one end of the tension spring combination rod 53 penetrates the mounting frame 51 and is fixedly connected to one end of the cross frame 54 close to the roller 56, and the roller 56 and the cross frame 54 have a tendency to move toward the gate 1 under the tension of the tension spring combination rod 53;

[0041] The detection mechanism 5 also includes a laser displacement sensor 58 installed inside the mounting frame 51 for detecting the displacement of the cross frame 54, and a controller 57 fixed to the mounting frame 51;

[0042] By adopting the above scheme, the worm 44 is rotated to drive the worm wheel 42 and the spline shaft 41 to rotate, so that the spline shaft 41 drives the convex shaft 1 411 to slide in the spiral groove 341, thereby pushing the limit column 43 to squeeze the dam body 2. At this time, the bracket assembly 3 is fixed on the dam body 2 as a whole. Then the operator rotates the screw combination gasket 52 to fix the mounting frame 51 on the connecting frame 31 or the connecting rod 2 34, and at the same time, the roller 56 is brought into contact with the water-facing surface of the gate 1. Then, the gate 1 is lifted by the hoist and the roller 56 is driven to rotate. The height of the gate 1 is recorded and the data is transmitted to the controller 57. When the surface of the gate 1 is tilted, the roller 56 drives the cross frame 54 to move in the horizontal direction. At the same time, the movement of the cross frame 54 is detected by the laser displacement sensor 58 and recorded and transmitted to the controller 57 and combined with the height of the gate 1, so as to facilitate the calculation of the inclination angle of the gate 1 within any vertical height range.

[0043] It is worth noting that: the horizontal displacement of the cross frame 54 is recorded as |L|, the height of the gate 1 is |H|, and any height difference of the gate 1 in the same vertical direction is recorded as |h|, then the inclination angle of the gate 1 α=arctan(|L| / |H|), so the inclination angle of the gate 1 at any height in the same vertical direction is α=arctan(|L| / |h|).

[0044] like Fig.10 As shown, a rubber ring 511 is fixedly connected to the mounting frame 51 and is movably sleeved on the outside of the tension spring assembly rod 53;

[0045] By adopting the above solution, the resistance of the tension spring combination rod 53 when moving is increased by the rubber ring 511, thereby ensuring the stability of the tension spring combination rod 53 and the cross frame 54 when moving in the horizontal direction.

[0046] like Figure 1 , Figure 2 , Figure 4-9 and Fig.11 As shown, one end of the connecting rod 33 close to the elastic bayonet 32 ​​is movably connected with a top shaft 331 that can abut against the elastic bayonet 32;

[0047] One end of the spline shaft 41 away from the limiting column 43 is movably connected to a top block 412 located outside the connecting rod 1 33, and one end of the top block 412 can extend into the inside of the connecting rod 1 33 and abut against the top shaft 331;

[0048] In the initial state, the top block 412 squeezes the elastic latch 32 through the top shaft 331 so that the elastic latch 32 releases the connection with the connecting rod 1 33;

[0049] The end of the second connecting rod 34 away from the connecting frame 31 is hook-shaped and can be hung on the top of the gate 1; the end of the second connecting rod 34 close to the limiting column 43 is elastically connected to a top plate 431 whose end is fixedly connected to the limiting column 43, and the top plate 431 has a tendency to move away from the limiting column 43 under its own tension;

[0050] One end of the second connecting rod 34 close to the top plate 431 is movably connected to a pressing plate 433, and an inclined groove 434 is provided on the pressing plate 433. The top plate 431 is fixedly connected to an inclined groove 434 that can move along the second convex shaft 432;

[0051] An electric screw assembly 332 is fixedly installed inside the second connecting rod 34. The screw portion of the electric screw assembly 332 is threadedly sleeved inside the first connecting rod 33 and is used to drive the first connecting rod 33 to move inside the second connecting rod 34.

[0052] By adopting the above scheme, the operator resets the fixing assembly 4, and during the resetting process, the spline shaft 41 drives one end of the top block 412 to squeeze the elastic pin 32 through the top shaft 331 to make the elastic pin 32 disengage from the connecting rod 1 33, and then rotates the connecting rod 2 34 to drive the connecting rod 1 33 to rotate to a vertical state, and hangs the end of the connecting rod 2 34 on the top of the gate 1. Then the operator rotates the worm 44 again to make the limit column 43 move upward. At this time, the limit column 43 will also drive the top plate 431 to move, thereby making the convex shaft 2 432 move in the inclined groove 434, so that the connecting rod 2 34 is fixed on the gate 1. Then the operator drives the connecting rod 1 33 to drive the connecting frame 31 and the detection mechanism 5 downward by running the electric screw assembly 332 to realize the detection of the inclination of the middle and lower part of the gate 1. At this time, the operator can calculate the inclination angle of the gate 1 according to the horizontal displacement of the cross frame 54 and the distance moved in the vertical direction by the connecting rod 1 33.

[0053] like Figure 4-Figure 7 and Fig. 9 As shown, the hook portion of the second connecting rod 34 is also fixedly connected to a fixing block 342, a positioning groove 441 is formed on the top of one worm 44, and a positioning block 442 that can be inserted into the positioning groove 441 is fixedly connected to the top of the other worm 44;

[0054] By adopting the above scheme, the fixing assembly 4 is driven to rotate by rotating the two sets of connecting rods 34. When the positioning block 442 on one of the worm gears 44 is inserted into the positioning groove 441 on the other worm gear 44, the connecting rod 34 is in a vertical state. At this time, the operator can drive the other set of worm gears 44 to rotate by rotating one set of worm gears 44, which is more convenient for fixing the device. At the same time, through the setting of the fixing block 342, when the connecting rod 34 is hung on the gate 1, the water-facing surface of the gate 1 can be abutted against the fixing block 342. At this time, a gap is left between the connecting rod 34 and the water-facing surface of the gate 1, which makes it easier for the detection mechanism 5 to detect the inclination of the gate 1.

[0055] like Figure 4 , Figure 8 and Fig.10 As shown, a gear 1 311 is fixedly connected to the hinge shaft of the connecting rod 1 33 and the connecting frame 31, and a gear 2 312 is equidistantly and movably installed on the connecting frame 31, two adjacent gears 2 312 are meshed, and the gear 2 312 close to the gear 1 311 is meshed with the gear 1 311, and a cover 313 for sealing the gear 2 312 and the gear 1 311 inside the connecting frame 31 is also fixedly installed on the connecting frame 31;

[0056] By adopting the above solution, the gear 1 311 and the gear 2 312 are arranged, so that the two groups of connecting rods 1 33 and connecting rods 2 34 can be rotated synchronously.

[0057] The working principle and use process of the present invention:

[0058] First, the operator rotates the worm 44 to drive the worm wheel 42 and the spline shaft 41 to rotate. The spline shaft 41 will drive the cam 411 to slide in the spiral groove 341, thereby pushing the limit column 43 to squeeze the dam body 2. Since the connecting frame 31 and the connecting rod 1 33 are connected in the same straight line through the elastic bayonet 32, the bracket assembly 3 is fixed on the dam body 2 as a whole. Then the operator rotates the screw combination gasket 52 to fix the mounting frame 51 on the connecting frame 31 or the connecting rod 2 34, and at the same time, the roller 56 contacts the water-facing surface of the gate 1. Then, the gate 1 is lifted by the hoist and the roller 56 is driven to rotate. The height of the gate 1 is recorded and the data is transmitted to the controller 57. When the surface of the gate 1 is tilted, the roller 56 will drive the cross frame 54 to move in the horizontal direction. At the same time, the movement of the cross frame 54 will be detected by the laser displacement sensor 58 and recorded and transmitted to the controller 57 and combined with the height of the gate 1, so as to calculate the inclination angle of the gate 1.

[0059] When the gate 1 cannot be lifted, the operator first resets the fixing assembly 4. At this time, the spline shaft 41 will drive one end of the top block 412 to squeeze the elastic latch 32 through the top shaft 331 during the resetting process, so that the elastic latch 32 is separated from the connecting rod 1 33, and then the connecting rod 2 34 is rotated to drive the connecting rod 1 33 to rotate to a vertical state, and the end of the connecting rod 2 34 is hung on the top of the gate 1. Then the operator rotates the worm 44 again to make the limit column 43 move upward. At this time, the limit column 43 will also drive the top plate 431 to move, thereby making the convex shaft 2 432 move in the inclined groove 434, so that the connecting rod 2 34 is fixed on the gate 1. Then the operator drives the connecting rod 1 33 to drive the connecting frame 31 and the detection mechanism 5 downward by running the electric screw assembly 332 to detect the inclination of the middle and lower part of the gate 1. At this time, the operator can calculate the inclination angle of the gate 1 according to the horizontal displacement of the cross frame 54 and the distance moved in the vertical direction by the connecting rod 1 33.

[0060] It should be noted that: one end of the elastic pin 32 that is engaged with the connecting rod 33 is provided with a slope. When the top block 412 squeezes the elastic pin 32 through the electric screw assembly 332 to contact the connecting rod 33, the rotation of the connecting rod 33 can squeeze the elastic pin 32 completely out of the connecting rod 33.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0062] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
