Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a reverse hydraulic water-stop steel gate, including a base 1, a baffle 2 connected to one side of the surface of the base 1, a lifting mechanism 3 provided on one side of the surface of the base 1, and an anti-fall mechanism 4 provided on one side of the surface of the base 1.

[0021] The fall prevention mechanism 4 includes a hollow block 401, a second threaded hole 402 on one side of the surface of the base 1, a cylindrical head bolt 403 connected to one side of the surface of the base 1, a slot 404 on the surface of the baffle 2, and a rotary knob 405 connected to one end of the cylindrical head bolt 403. Through the arrangement of the hollow block 401, the second threaded hole 402, the cylindrical head bolt 403, the slot 404, and the rotary knob 405, in use, to prevent the gate from falling, first align the second threaded hole 402 with the slot 404, then rotate the rotary knob 405 on one side of the hollow block 401. The rotary knob 405 drives the cylindrical head bolt 403 to rotate, and then the cylindrical head bolt 403 begins to continuously connect with the threaded hole 402 on the surface of the base 1. When the rotary knob 405 is rotated to a certain extent, the cylindrical head bolt 403 begins to engage with the interior of the slot 404, thereby limiting the position of the baffle 2 and achieving the fall prevention function.

[0022] Furthermore, one end of the cylindrical head bolt 403 passes through the hollow block 401 and is connected to the rotary knob 405. The hollow block 401 is provided with two sets. With the rotary knob 405, when the rotary knob 405 is rotated during use, the rotary knob 405 can drive the cylindrical head bolt 403 to rotate, thereby facilitating the subsequent insertion of one end of the cylindrical head bolt 403 into the inside of the slot 404.

[0023] Furthermore, the second threaded hole 402 is aligned with the slot 404, and the cylindrical head bolt 403 matches the size of the second threaded hole 402. With the cylindrical head bolt 403 in use, when the cylindrical head bolt 403 is fitted into the slot 404, it can limit the position of the baffle 2, thereby playing a role in preventing it from falling.

[0024] Furthermore, the lifting mechanism 3 includes a protective box 301, a motor 302 mounted on one side of the base 1, a first threaded hole 303 opened on one side of the baffle 2, a limit groove 304 opened inside the baffle 2, a connecting rod 305 connected to one end of the motor 302, a first gear 306 connected through one end of the connecting rod 305, a second gear 307 meshing with one side of the surface of the first gear 306, a first threaded rod 308 connected to one side of the surface of the second gear 307, and a stop block 309 connected to one end of the first threaded rod 308. When the gate is raised or lowered, the first... First, control the motor 302 inside the start protection box 301. The motor 302 starts to rotate. Then, the motor 302 drives the connecting rod 305 to rotate. Then, the connecting rod 305 drives the second gear 307 to rotate through the first gear 306. After that, the second gear 307 drives the first threaded rod 308 to rotate. At this time, the first threaded rod 308 moves through the threaded hole 303, thereby driving the baffle 2 to be raised and lowered. At the same time, the stop block 309 connected to one end of the first threaded rod 308 is inside the limiting groove 304, which can prevent the first threaded rod 308 from disengaging from the first threaded hole 303.

[0025] Furthermore, one end of the first threaded rod 308 passes through the base 1 and is connected to the second gear 307. The first threaded rod 308 is threadedly connected to the first threaded hole 303. Through the setting of the first threaded rod 308, when the first threaded rod 308 rotates, it can drive the baffle 2 to rise and fall by performing threaded movement with the first threaded hole 303.

[0026] Furthermore, the motor 302 is installed inside the protective box 301. With the protective box 301 installed, the motor 302 can be protected from wind and sun during use, and also prevented from getting wet in the rain, thereby increasing the service life of the motor 302.

[0027] Furthermore, the stop 309 is fitted inside the limiting groove 304. By setting the stop 309, during use, the stop 309 can prevent the first threaded rod 308 from disengaging from the first threaded hole 303 when rotating, thereby preventing the baffle 2 from falling off.

[0028] Working principle: When raising or lowering the gate, the motor 302 inside the start protection box 301 is first controlled to rotate. The motor 302 then drives the connecting rod 305 to rotate. The connecting rod 305 then drives the second gear 307 to rotate through the first gear 306. The second gear 307 then drives the first threaded rod 308 to rotate. At this time, the first threaded rod 308 moves through the threaded hole 303, thereby driving the baffle 2 to adjust its height. At the same time, the stop block 309 connected to one end of the first threaded rod 308 is in the limiting groove 304. The first threaded rod 308 can be prevented from disengaging from the first threaded hole 303. When preventing the gate from falling, the second threaded hole 402 is first aligned with the slot 404. Then, the rotary knob 405 on one side of the hollow block 401 is rotated. The rotary knob 405 drives the cylindrical head bolt 403 to rotate. Then, the cylindrical head bolt 403 begins to continuously connect with the thread of the second threaded hole 402 on the surface of the base 1. When the rotary knob 405 is rotated to a certain extent, the cylindrical head bolt 403 begins to engage with the interior of the slot 404, thereby completing the limiting of the baffle 2 and thus playing the role of preventing falling.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
