Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a water conservancy dam gate inclination quality inspection device. Background Art

[0002] In the field of water conservancy construction, during and after the installation of the gate, in order to ensure the normal use of the gate, relevant equipment will be used to detect the verticality of the gate (including the gate's guide rails, etc.) after installation to prevent safety hazards caused by excessive inclination (if the inclination is too large, leakage may occur during subsequent water flow impact, or even collapse of the gate and its ancillary equipment).

[0003] In the existing technology, the inclination detection method of the gate or its attachment is generally that the staff uses a pendant to detect from a high position of the gate or its attachment, and then obtains the verticality of the gate or its attachment by observing the distance between the rope connected to the pendant and the monitoring surface of the gate or its attachment. However, this detection method relies on naked eye observation, which is highly subjective and prone to misjudgment. At the same time, it is also impossible to accurately measure the inclination angle, resulting in only a rough estimate based on experience during maintenance and correction. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model provides a device for inspecting the inclination quality of a water conservancy dam gate. Figure 1-3 As shown, it includes a fixed rod 1 and a balancing rod 2, and the middle position of the balancing rod 2 is rotatably connected to the fixed rod 1 through a rotating shaft.

[0021] like Figure 1As shown, the fixing rod 1 is provided with positioning holes 14 symmetrically on both sides of the rotating shaft, and the straight line formed by the two positioning holes 14 is parallel to the fixing rod 1. The balancing rod 2 is longitudinally slidably connected with positioning rods 15 corresponding to the positioning holes 14. When the two positioning rods 15 are inserted into the two corresponding positioning holes 14, the balancing rod 2 is in a parallel state with the fixing rod 1.

[0022] A level 13 is provided on the balance pole 2. The level 13 is used for measuring the level of the balance pole 2.

[0023] like Figure 1 As shown, two clamping mechanisms for clamping the gate 19 are symmetrically arranged on both sides of the rotating shaft on the fixing rod 1.

[0024] Specifically, the clamping mechanism includes a right angle frame 3, a clamping plate 4, and an adjusting screw 7. The vertical section of the right angle frame 3 is fixed on the fixed rod 1, and the transverse section of the right angle frame 3 is parallel to the fixed rod 1. A slideway 5 is horizontally provided on the transverse section of the right angle frame 3. A slider 6 is adapted to slide in the slideway 5. The top end of the adjusting screw 7 is pivotally connected to the slider 6. The middle section of the adjusting screw 7 passes through the right angle frame 3 and is threadedly connected thereto. The clamping plate 4 is located outside the slideway 5, and the slider 6 is connected to the clamping plate 4 through a connection. The rotation of the adjusting screw 7 can adjust the slider 6 to slide in the slideway 5, and the slider 6 is linked to the position of the clamping plate 4 through a connecting rod.

[0025] In order to make the clamping more accurate, a linear scale 16 is provided on the transverse section of the right-angle bracket 3 along its length direction, and a pointer 17 corresponding to the linear scale 16 is provided on the slider 6.

[0026] When the clamping plates 4 on both sides clamp the gate 19, the two sliders 6 are adjusted according to the linear scale 16 on the right-angle frame 3; after the two clamping plates 4 finally clamp the gate 19, the values ​​of the linear scale 16 corresponding to the pointers 17 on the two sliders 6 should remain consistent, so that the gate 19 is on the center line of the rotating shaft of the balance rod 2 and the fixed rod 1, which is convenient for accurately measuring the inclination of the gate 19.

[0027] Angle detection mechanisms using the principle of gravity are symmetrically arranged at both ends of the balance bar 2 .

[0028] like Figure 1 As shown, the angle detection mechanism includes a semicircular ruler 8, a rotating arm 9, and a pendant 10. The semicircular ruler 8 is arranged at the end of the balance pole 2. The rotating arm 9 is rotatably connected to the end of the balance pole 2, and the rotating shaft is concentric with the semicircular ruler 8. The pendant 10 is arranged at the bottom end of the rotating arm 9 through a hanging rope. The pendant 10 can be a steel cone. An angle scale 18 is arranged on the semicircular ruler 8 along the direction of its radius. When the balance pole 2 rotates, the rotating arm 9 will swing to a state perpendicular to the horizontal plane under the gravity of the pendant 10. An indicator needle corresponding to the angle scale 18 can be arranged on the radial line of the rotating arm 9.

[0029] An arc-shaped slide groove 11 is provided on the semicircular ruler 8 along the direction of the radius, and a guide block 12 connected to the rotating arm 9 is slidably adapted in the arc-shaped slide groove 11. A pulley is rotatably provided on the surface of the guide block 12 that contacts the arc-shaped slide groove 11 to facilitate the sliding of the guide block 12.

[0030] Working principle: Step 1, after the positioning rod 15 is disengaged from the positioning hole 14, the balance rod 2 is in a horizontal state, and the value A indicated by the indicator needle on the rotating arm 9 is recorded.

[0031] Step 2: clamp the right-angle frame 3 on the reference object 20 (such as the embankment or support pile beside the gate), insert the positioning rod 15 on the balance rod 2 into the positioning hole 14, and record the value B indicated by the indicator needle on the rotating arm 9.

[0032] Step three, clamp the right-angle bracket 3 on the gate 19 to be tested, insert the positioning rod 15 on the balance rod 2 into the positioning hole 14, and record the value C indicated by the indicator needle on the rotating arm 9.

[0033] Step 4: Analyze the angle difference between the values ​​B and C and the value A, so as to obtain the inclination of the gate 19 relative to the reference object 20 or relative to the horizontal plane.

[0034] 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.
