DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Reference Figure 1 - Figure 5 An embodiment provided by the utility model: the automatic opening and closing device suitable for integrated gate, including embankment 1 and scraper 203, the outer side of embankment 1 is fixedly installed with support frame 201, the top of support frame 201 is installed with hydraulic cylinder 202, the output end of hydraulic cylinder 202 is fixedly connected with fixed plate 204, the inner side wall of fixed plate 204 is provided with cavity, the inside of cavity is slidably connected with movable plate 209, one side of movable plate 209 is fixedly connected with pull rod 205, the other side of movable plate 209 is fixedly connected with clamping rod 207, the outside of pull rod 205 is provided with spring 210, scraper 203 is arranged at the outer side of embankment 1, the top of scraper 203 is fixedly connected with fixed block 206, the outer side of fixed block 206 is provided with clamping groove 208, the outer side of embankment 1 is installed with opening and closing assembly. One end of spring 210 is fixedly connected with the outer side of movable plate 209, the other end of spring 210 is fixedly connected with the inner wall of cavity;

[0024] Specifically, when starting hydraulic cylinder 202, the action of hydraulic cylinder 202 drives scraper 203 to reciprocate up and down. This process makes scraper 203 clean silt and sundries along the outer surface of gate 303, so that the normal opening of gate 303 is ensured, without relying on manual cleaning, greatly improving the operation efficiency and reducing the artificial burden.

[0025] After the cleaning is completed, the user can pull the pull rod 205 outward, so that the movable plate 209 moves along the inner wall of the cavity, so that the clamping rod 207 is separated from the internal groove of the clamping groove 208. At this time, the scraper 203 moves downward under the action of gravity, and the fixed block 206 is separated from the groove at the bottom of the fixed plate 204, and the disassembly of the scraper 203 is completed

[0026] The opening and closing assembly comprises a U-shaped frame 4 fixedly connected to the outer side of the dam 1, a servo motor 304 mounted on the outer side of the U-shaped frame 4, a transmission rod fixedly connected to the output end of the servo motor 304, two first bevel gears 305 fixedly connected to the outer side of the transmission rod, two drive screws 301 movably connected to the bottom end of the U-shaped frame 4 through bearings, a second bevel gear 306 fixedly connected to the top end of the drive screw 301, and a threaded block 302 screwedly connected to the outer side of the drive screw 301.

[0027] Specifically, after starting the servo motor 304, the transmission rod starts to rotate, and then the two first bevel gears 305 rotate synchronously. Since the first bevel gears 305 and the second bevel gears 306 are meshed with each other, the rotation of the first bevel gears 305 can drive the second bevel gears 306 to rotate synchronously, which further drives the rotation of the drive screws 301. With the rotation of the drive screws 301, the threaded block 302 moves up and down along the outer surface thereof. At this time, the traction force generated by the threaded block 302 causes the gate 303 to move synchronously, thereby realizing the opening and closing thereof. By adopting the double-screw design, the device can provide more uniform force distribution, so that the gate 303 is more stable during opening and closing, reducing mechanical wear and vibration caused by uneven force, thereby ensuring the normal operation of the gate 303.

[0028] The outer sides of the two second bevel gears 306 are respectively meshed with the outer sides of the corresponding first bevel gears 305, and the outer surface of the gate 303 is in close contact with the outer side of the scraper 203;

[0029] Further comprising a support bottom plate 5 fixedly connected to the outer bottom of the dam 1, a rotating seat 6 rotatably connected to the bottom of the drive screw 301, and the rotating seat 6 is fixedly connected to the top of the support bottom plate 5.

[0030] Specifically, the support bottom plate 5 is fixedly connected to the outer bottom of the dam 1 as a basic component, ensuring the stability and support force of the entire cleaning device. The support bottom plate 5 is made of high-strength material to withstand environmental pressure and mechanical impact that may be suffered during long-term use.

[0031] On the top of the support base 5, a rotating seat 6 is installed. The rotating seat 6 is connected to the bottom of the drive screw 301 through a rotating connection, forming a key node for power transmission. This design allows the rotation of the drive screw 301 to be effectively transmitted to the rotating seat 6, thereby achieving the up-and-down reciprocating motion of the scraper 203. The fixed connection of the rotating seat 6 ensures that it does not shift or loosen during operation, improving the safety and reliability of the entire device.

[0032] The design of the drive screw 301 adopts a precise thread structure, which can achieve smooth and efficient linear movement during rotation. This screw-driven method not only provides good mechanical properties, but also facilitates the adjustment of the cleaning depth and working frequency of the scraper 203 to adapt to cleaning needs in different water areas and environmental conditions. The operation of the entire cleaning device becomes more efficient, and the combination of the support base 5 and the rotating seat 6 provides a solid support foundation for the system, allowing the scraper 203 to move stably along the surface of the gate 303 during cleaning, effectively removing silt and debris, and ensuring the normal operation of water conservancy facilities.

[0033] The longitudinal section of the clamping rod 207 is square, and one end of the clamping rod 207 is inserted into the inner wall of the clamping groove 208; the end of the pull rod 205 away from the movable plate 209 penetrates the outer wall of the fixed plate 204 and extends to the outside, and the outside of the pull rod 205 is provided with anti-skid lines.

[0034] Specifically, the longitudinal section of the clamping rod 207 is square, which can form a good insertion fit with the inner wall of the clamping groove 208. This design makes the positioning of the clamping rod 207 in the clamping groove 208 more stable, effectively preventing accidental loosening or deviation during use, thereby enhancing the overall safety and reliability of the system.

[0035] The pull rod 205 is the main operating component of the device. Its one end penetrates the outer wall of the fixed plate 204 and extends to the outside, which is convenient for the operator to pull. The outside of the pull rod 205 is provided with anti-skid lines, which not only improves the comfort of operation, but also enhances the firmness of grip, ensuring that the hand does not slip when applying force, thereby improving the safety of operation.

[0036] The operation principle of the device is relatively simple and efficient. When the operator pulls the pull rod 205 outward, the force applied to the pull rod 205 is transmitted to the movable plate 209 through its structure. The movable plate 209 moves along the inner wall of the cavity and gradually pushes the clamping rod 207, so that the clamping rod 207 is separated from the groove inside the clamping groove 208. This separation process is smooth and stable, effectively avoiding the situation that the clamping rod 207 is stuck or hindered during operation.

[0037] Working principle: when using the device, firstly, the hydraulic cylinder 202 is started to drive the scraper 203 to move up and down reciprocatingly, so that the scraper 203 moves along the outer surface of the gate 303 to clean the silt and sundries on the outer surface of the scraper 203, ensuring the normal opening of the gate 303 without manual cleaning, which is simple and convenient to operate; in addition, the pull rod 205 is pulled outward to move the movable plate 209 along the inner wall of the cavity, thereby separating the clamping rod 207 from the groove in the clamping groove 208, and the scraper 203 moves downward under the action of gravity, at this time, the fixed block 206 is separated from the groove at the bottom of the fixed plate 204, thereby completing the disassembly of the scraper 203, which is simple to operate and convenient for people to use.

[0038] The servo motor 304 is started to rotate the transmission rod, and further drive the two first bevel gears 305 to rotate synchronously, since the first bevel gear 305 and the second bevel gear 306 are meshed with each other, the rotation of the first bevel gear 305 can drive the second bevel gear 306 to rotate synchronously, further driving the drive screw 301 to rotate, thereby moving the threaded block 302 up and down along the outer surface of the drive screw 301, at this time, the gate 303 moves synchronously under the action of the traction force of the threaded block 302, thereby realizing the opening and closing of the gate 303, and the double screw design provides more uniform force distribution, so that the gate 303 is more stable during opening and closing, reducing mechanical wear and vibration caused by uneven force, and ensuring the normal opening and closing of the gate 303.

[0039] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
