[0002] A hydropower station is a facility that uses water energy to generate electricity. The water in the reservoir is regulated and stored through the dam, and then the water flow is introduced into the hydro-generator set through the water diversion structure. The kinetic energy of the water flow is used to rotate the turbine, thereby driving the coaxial generator, which converts mechanical energy into electrical energy. When inspecting and maintaining the electrical equipment of a hydropower station, the staff often use safety protection brackets to facilitate the construction of the staff and the safety protection of the staff.

[0003] It is pointed out in the related technology that most of the brackets have poor connection stability in order to be quickly disassembled and installed. When workers are above the brackets, the brackets will shake, which poses a high safety hazard and is not conducive to the safe progress of construction. For example, the prior art publication number CN213897033U provides a safety protection bracket for hydropower station construction. When in use, the loading plate is sleeved on the top of the supporting leg, and then the two ends of the first connecting rod are inserted into the interior of the connecting sleeve, the second connecting rod is threadedly connected to one end of the connecting tube, and the other end of the third connecting rod is threadedly connected to the other end of the connecting tube. The connecting tube is rotated to move the second connecting rod and the third connecting rod toward the interior of the connecting tube, and then the slider is rotated to push the fixing plug toward the interior of the connecting sleeve, and then the fixing plug is squeezed into the interior of the connecting sleeve to fix the supporting leg. Then the workers can move to the loading plate to work, and the bracket is fixed more firmly, so that the stability of the bracket is higher.

[0004] However, the height of the safety protection bracket is not easy to adjust, and the construction height is relatively limited, so that a better construction quality of the hydropower station cannot be achieved.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, provides a support mechanism, including a support assembly 100, including a lifting member 101, a check member 102 arranged on one side of the lifting member 101, and a buffer member 103 arranged inside the check member 102.

[0034] The lifting member 101 includes a base 101a, a rotating seat 101b and a stop plate 101c. The rotating seat 101b is rotatably set on the inner wall of the base 101a.

The stop plate 101c is slidably set on the inner walls of the square holes on the sides of the rotating seat 101b and the base 101a to prevent the rotating seat 101b and the base 101a from rotating relative to each other.

[0035] The lifting member 101 also includes a rotating cylinder 101d, a side rod 101e, a spiral groove 101f, a lifting column 101g and a clamping rod 101h. The rotating cylinder 101d is rotatably set on the inner wall of the rotating seat 101b, the side rod 101e is fixedly set on the side of the rotating cylinder 101d, the spiral groove 101f is opened on the side of the rotating cylinder 101d, the lifting column 101g is slidably set on the inner wall of the rotating cylinder 101d, the clamping rod 101h is fixedly set on the side of the lifting column 101g, and the clamping rod 101h is slidably set on the inner wall of the spiral groove 101f. When the lifting column 101g moves up and down, the clamping rod 101h slides relative to the inner wall of the spiral groove 101f. Since the lifting column 101g is generally in a fixed device, when the clamping rod 101h slides on the surface of the spiral groove 101f, the rotating cylinder 101d will rotate due to the squeezing of the spiral groove 101f by the clamping rod 101h.

[0036] The check member 102 includes a working groove 102a, a stopper 102b, a spring 102c, a side plate 102d and a limit block 102e. The working groove 102a is opened at the top of the rotating seat 101b and is located on one side of the rotating cylinder 101d. The stopper 102b is rotatably set on the inner wall of the working groove 102a. The two ends of the spring 102c are respectively fixed on the bottom of the stopper 102b and the inner wall of the working groove 102a. The spring 102c helps the stopper 102b to reset after being squeezed. The side plate 102d is fixed on the side of the stopper 102b. The limit block 102e is fixed on the inner wall of the working groove 102a. The side plate 102d and the limit block 102e cooperate with each other to prevent the stopper 102b from flipping over. The limit block 102e and the side plate 102d are abutted.

[0037] The buffer member 103 includes an arc groove 103a, a buffer hole 103b, a slide bar 103c, a spring 103d and a rubber pad 103e. The arc groove 103a is provided on the side of the stopper 102b.

The slide bar 103c is slidably arranged on the inner wall of the buffer hole 103b. The spring 103d is provided on the side of the arc groove 103a. The two ends of 3d are respectively fixed on the inner wall of the buffer hole 103b and the side of the slide bar 103c, the rubber pad 103e is fixed on the end of the slide bar 103c and slidably set on the inner wall of the arc groove 103a. When not squeezed, the rubber pad 103e is extended out by the slide bar 103c, but when the side bar 101e is stuck in the arc groove 103a, the rubber pad 103e and the spring 103d provide a certain buffer for the clamping rod 101h.

[0038] Usage process: The support assembly 100 is used to support objects that move up and down, and can follow the objects that move up and down. When in use, the lifting column 101g and the object to be lifted are fixed together. When the object is lifted, the fixed lifting column 101g uses the clamping rod 101h to drive the rotating cylinder 101d to rotate. During the rotation, the side rod 101e squeezes the stopper 102b, and the stopper 102b is pressed into the working groove 102a after being squeezed. After the side rod 101e leaves, it is restored by the spring 102c. When the lifting stops, the object moves downward due to gravity, but the side rod 101e will be stuck in the arc groove 103a, and the buffer 103 provides buffering to extend the service life of the stopper 102b.

[0039] Example 2, reference Figures 4 to 7 , which is the second embodiment of the utility model, this embodiment further provides a safety protection bracket, including a supporting mechanism, and a lifting assembly 200, including a structural member 201, a driving member 202, and a limiting member 203, wherein the driving member 202 is arranged on one side of the structural member 201, and the limiting member 203 is arranged on one side of the driving member 202.

The toggle lever 202c is rotatably arranged at the end of the driving shaft 202a. The tooth block frame 202d is provided at the bottom of the driving shaft 202a. 2d is hinged on the side of the toggle rod 202c, the lifting gear 202e is sleeved on the side of the driving shaft 202a, the lifting guide plate 202f is fixedly set on the bottom of the safety frame plate 201d, the fixed rail 202g is fixedly set on the inner bottom of the support frame 201a, the lifting guide plate 202f is slidably set on the inner wall of the fixed rail 202g, the tooth plate 202h is fixedly set on one side of the lifting guide plate 202f, and the tooth plate 202h is engaged with the lifting gear 202e.

[0042] The limiting member 203 includes a ratchet 203a, a check tooth 203b, a lever 203c, a limiting plate 203d, a fixing plate 203e and a spring 203f. The ratchet 203a is sleeved on the side of the driving shaft 202a. The check tooth 203b is rotatably arranged on the side of the connecting cross plate 201c. The lever 203c is fixedly arranged on the side of the check tooth 203b. The lever 203c is used to pull the check tooth 203b out of the teeth of the ratchet 203a. The limiting plate 203d is fixedly arranged on the side of the connecting cross plate 201c. It is arranged on the side of the connecting horizontal plate 201c, the side of the check tooth 203b abuts against the side of the limiting plate 203d, the fixed plate 203e is fixedly arranged on the side of the connecting horizontal plate 201c, and the two ends of the spring three 203f are fixedly arranged on the side of the fixing plate 203e and the side of the check tooth 203b. Under the blocking of the limiting plate 203d and the spring three 203f on both sides, the rotation range of the check tooth 203b is limited, thereby preventing the check tooth 203b and the ratchet 203a from being unhooked.

[0043] Usage process: put the device in the use position, then rotate the toggle rod 202c in the driving member 202 counterclockwise, so that the card block frame 202d connected to it can be lifted upward, and at this time, the card block frame 202d is provided with the card block and the toggle gear 202b is in a state of engagement, and the card block frame 202d will drive the toggle gear 202b to rotate counterclockwise while moving counterclockwise. When the toggle gear 202b rotates a certain angle, it will rotate clockwise. The lever 202c is toggled so that the tooth block frame 202d can move clockwise, so that the block is stuck in the tooth groove outside the next toggle gear 202b, and the next rotation is performed; the rotation of the toggle gear 202b drives the limiter 203 to operate, so as to prevent the toggle gear 202b from reversing, thereby preventing the safety frame plate 201d from falling after the height is adjusted; when the driving shaft 202a is reversed, the check tooth 203b is stuck in the ratchet 203a, so as to prevent the ratchet 203a from rotating;

[0044] The rotation of the toggle gear 202b drives the lifting gear 202e in the lifting assembly 200 to rotate through the driving shaft 202a, and the rotation of the lifting gear 202e drives the lifting guide plate 202f to rise through the tooth plate 202h. The rising of the lifting guide plate 202f drives the safety frame plate 201d to rise, and then the working height is adjusted. After the adjustment is completed, the rotation of the driving member 202 can be stopped, and then the staff can climb onto the safety frame plate 201d to work on the top of the safety frame plate 201d. After the support mechanism is installed, if the lifting gear 202e is damaged or slips, causing the safety frame plate 201d to drop, the support mechanism can provide emergency protection to ensure the safe use of the safety protection frame.

[0048] Usage process: The rotation of the lifting gear 202e can also drive the large pulley 301a and the small pulley 301b in the transmission member 301 to rotate through the connecting rod. The diameters of the large pulley 301a and the small pulley 301b are different, and the diameter of the large pulley 301a is larger than that of the small pulley 301b. They are respectively used to drive the secondary pulleys 301c arranged on both sides to rotate. One of the secondary pulleys 301c rotates in the opposite direction to the other linkage belt 301d wheel under the transmission of the transmission gear 1 301e and the transmission gear 2 301f, so that the connecting frames 302a on both sides can expand outwards to support the ground, which is used to improve the stability of the device standing on the ground after adjusting the height;

[0049] The rotation of the secondary pulley 301c drives the connecting frame 302a to rotate around, and the rotation of the large pulley 301a directly drives one of the linkage belt wheels 301d to rotate, and the diameter of the large pulley 301a is larger than the secondary pulley 301c, which is used for speed reduction, and the diameter of the second transmission gear 301f is also larger than the first transmission gear 301e, and the first transmission gear 301e directly drives another secondary pulley 301c to rotate, which is used for speed reduction, so that the connecting frame 302a can be slowly opened or retracted, and can be expanded to different angles according to different adjustment heights;

At this time, the screw sleeve 302e is rotated to cooperate with the adjusting screw 302d thread, so that the total length of the connecting frame 302a and the grounding frame 302c can be adjusted, so that the grounding frame 302c can contact the ground, so that the auxiliary component 300 can stand on the ground, and the telescopic rod 302b can achieve the effect of telescoping, which is used to stabilize the elongation or shortening of the connecting frame 302a and the grounding frame 302c;

[0051] When the height of the safety frame plate 201d needs to be lowered, the limiter 203 is unlocked, the latch block frame 202d is moved to the other side of the shifting gear 202b, and then the shifting gear 202b is driven to rotate clockwise.
