Description

Technical Field

[0001] The invention belongs to the technical field of sluice ice breaking, in particular to an ice breaking device for a sluice in a water conservancy project. Background Art

[0002] The sluice gate used in water conservancy projects is used to control the flow of the river or to intercept and block the river. In the winter when the temperature is low, the surface of the water source in the river will form an ice surface, which will cause the upgrading of the gate to be blocked by the ice surface and cannot be lowered underwater. The existing sluice ice-breaking device is a Chinese patent with the announcement number CN113322911B, which discloses an ice-breaking device for a sluice gate used in a water conservancy project, including an arc angle wheel, a transmission frame, a hammer block and an ice-breaking plate. The arc angle wheel is used to move the transmission frame up and down when rotating, and then the hammer block continuously hammers the ice-breaking plate to break the ice surface through the ice-breaking plate. This method can only be applied to the case where the ice surface is thin. If the ice surface is thick, it is difficult to break the ice surface by a single hammering method, and it is also easy to cause damage to the ice-breaking device itself. At the same time, the violent breaking method will also damage the gate slideway of the sluice gate through the stress of the ice surface. If the gate slideway is deformed, it will cause the gate to fail to descend normally.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a suspension rope and an ice crusher, and the cylinder runs to drive the overall shield to move downward so that the bottom of the shield abuts against the ice surface, and then controls the gate to descend and abut against the ice surface, so that the gate can close the inner side of the shield, and then the motor drives the fixed wheel to rotate, and the suspension rope is lowered through the movable wheel, so that the hanger and the vibration frame descend along the fixed block, so that the ice crusher contacts the ice surface, and due to the operation of the vibration motor, the vibration frame can be driven to vibrate at a high frequency through the bracket, so that the ice crusher hits the ice surface with high-frequency vibration, and the motor drives the movable arm and the movable wheel to rotate downward for a section, so that the suspension rope is disengaged from the movable wheel, and the movable wheel contacts the height limit of the vibration frame through the suspension rope, so that the vibration frame hits the ice surface downward through the ice crusher, and when the ice crusher is inserted into the ice surface, the surface layer of the ice surface is broken, and the design breaks the surface layer of the ice surface by means of high-frequency vibration, thereby avoiding damage to the device components caused by violent hammering and breaking, and also avoiding damage to the slideway of the sluice caused by the stress of the ice surface caused by hitting the ice surface.

[0014] The present invention provides a material trough and, before the vibration frame descends, the motor drives the rotating wheel to rotate, so that the industrial salt contained in the material box can be discharged into the material guide bin through the material trough and introduced into the internal upper part; after the vibration frame descends, the vibration generated by the operation of the vibration motor can simultaneously vibrate and spread the industrial salt on the swing blades, so that it is evenly distributed on the swing blades; when the vibration frame is pulled upward by the suspension rope to reset, the operation of the electromagnetic telescopic rod can drive the abutment plate and the inclined plate to move above the second abutment wheel and the first abutment wheel respectively; as the vibration frame rises, the second abutment wheel can first abut against the abutment plate, so that the abutment wheel The second and push rods push toward the inside of the vibration frame, the card rod will be disengaged from the square rod, and then the abutment wheel one will abut against the lower inclined surface of the round rod two, driving the connecting rod and the square rod to move laterally along the mounting block, and at the same time driving the meshing rubber gear to drive the pendulum blade to flip downward, and when the pendulum blade flips, the industrial salt on the pendulum blade is sprinkled onto the broken ice surface.

DETAILED DESCRIPTION

[0018] 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.

[0019] like Figures 1 to 13 As shown, the present invention provides an ice-breaking device for a water gate used in a water conservancy project, comprising a water gate 1, a mounting frame 2, a fixing frame 3, a cylinder 4, a protective cover 5, an ice-breaking mechanism 6 and a gate 10; The mounting frame 2 and the fixing frame 3 are fixed on the water gate 1 by bolts, the cylinder 4 is installed on the fixing frame 3, the shield 5 is connected to the output end of the cylinder 4, the ice crushing mechanism 6 is arranged on the shield 5, and the gate 10 is arranged on the water gate 1; The ice crushing mechanism 6 includes a connecting frame 61, which is installed on the protective cover 5. A fixed wheel 62 that can be driven by a motor is movably installed on the connecting frame 61. A movable arm 63 that can be driven by a motor is movably installed on one side of the connecting frame 61. A movable wheel 64 is movably installed on the movable arm 63. A suspension rope 65 is wound around the fixed wheel 62. The other end of the suspension rope 65 extends into the protective cover 5 through the movable wheel 64 and is connected to a hanger 66. Both sides of the hanger 66 are movably sleeved with fixed blocks 67 installed in the protective cover 5. A rubber buffer sleeve 68 is provided at the joint between the fixed block 67 and the hanger 66. A rubber buffer block 69 is connected to the bottom of the hanger 66. The bottom of the rubber buffer block 69 is connected to a vibration frame 610. The bottom of the vibration frame 610 is connected to a group of ice crushing cones 611. The top of the vibration frame 610 is connected to a bracket 612. A vibration motor 613 is installed above the bracket 612.

[0020] According to the above scheme, the operation of the cylinder 4 can drive the shield 5 to move downward as a whole, so that the bottom of the shield 5 contacts the ice surface, and then the gate 10 is controlled to descend and contact the ice surface, so that the gate 10 can close the inner side of the shield 5, and then the motor drives the fixed wheel 62 to rotate, and the suspension rope 65 is lowered through the movable wheel 64, so that the hanger 66 and the vibration frame 610 are lowered along the fixed block 67, so that the ice crusher 611 contacts the ice surface, and the operation of the vibration motor 613 can drive the vibration through the bracket 612. The movable frame 610 vibrates at high frequency, so that the ice-breaking cone 611 vibrates at high frequency to hit the ice surface. The motor drives the movable arm 63 and the movable wheel 64 to rotate downward a certain distance, so that the suspension rope 65 is disengaged from the movable wheel 64, and the movable wheel 64 contacts the height limit of the vibration frame 610 through the suspension rope 65, so that the vibration frame 610 can hit the ice surface downward through the ice-breaking cone 611. When the ice-breaking cone 611 is inserted into the ice surface, the surface layer of the ice surface is broken, thereby avoiding damage to the device components caused by violent hammering.

[0021] like Figures 4 to 8 As shown, a group of swing blades 614 are movably installed inside the vibration frame 610, and a group of rubber gears 615 coaxial with the swing blades 614 are movably installed outside the vibration frame 610.

[0022] With the above solution, since the rubber gear 615 drives the swing blade 614 to flip downward, the industrial salt on the swing blade 614 can be sprinkled onto the broken ice surface when the swing blade 614 flips, thereby accelerating the melting of the ice surface.

[0023] like Figures 4 to 8As shown, a group of mounting blocks 616 are connected to the outside of the vibration frame 610, and a square rod 618 is movably sleeved inside the mounting block 616. A rubber buffer sleeve 2 617 is provided at the sleeve of the mounting block 616 and the square rod 618. The outside of the square rod 618 is fixedly sleeved with rubber racks 619 of the same number as the rubber gears 615, and the rubber racks 619 can mesh with the rubber gears 615. A tension spring 1 620 located above the square rod 618 is connected between the mounting block 616 and the rubber racks 619.

[0024] By adopting the above solution, when the square rod 618 moves laterally along the mounting block 616, the rubber buffer sleeve 617 can be stretched, so that the rubber rack 619 moves and engages with the rubber gear 615, driving the swing blade 614 to flip downward, thereby driving the swing blade 614 to flip.

[0025] like Figures 4 to 8 As shown, the outer side of the vibration frame 610 is connected to a protective shell 622 located outside the rubber gear 615, the mounting block 616, the square rod 618 and the rubber rack 619, one end of the square rod 618 is connected to a connecting rod 623 that can move on the protective shell 622, and the other end of the connecting rod 623 extends to the outside of the protective shell 622 and is movably mounted with a wheel 624.

[0026] By adopting the above solution, when the wheel 624 is subjected to external squeezing force, the connecting rod 623 and the square rod 618 can be moved laterally along the mounting block 616, thereby conveniently driving the square rod 618 to be laterally displaced.

[0027] like Figures 4 to 8 As shown, a push rod 625 is movably mounted inside the vibration frame 610 and the protective shell 622, and a second wheel 626 located on the outside of the protective shell 622 is movably mounted on one end of the push rod 625. A clamping rod 627 located inside the vibration frame 610 is connected to the push rod 625 below, and the other end of the clamping rod 627 extends into the protective shell 622 and is clamped in the square rod 618. A second tension spring 621 is connected to the push rod 625, and the other end of the second tension spring 621 is connected to the inner wall of the vibration frame 610.

[0028] By adopting the above scheme, the locking of the locking rod 627 can prevent the square rod 618 from accidentally moving when the vibration frame 610 vibrates. When the second wheel 626 is subjected to extrusion force, the second wheel 626 and the push rod 625 can be pushed toward the inside of the vibration frame 610. At this time, the tension spring 621 is stretched, and the locking rod 627 will be disengaged from the square rod 618, thereby releasing the fixation of the square rod 618.

[0029] like Fig. 9 and Fig.10As shown, it also includes a pushing mechanism 8, which is installed on the protective cover 5. The pushing mechanism 8 includes an electromagnetic telescopic rod 81, which is installed in the protective cover 5. The output end of the electromagnetic telescopic rod 81 extends to the outside of the protective cover 5 and is connected to a connecting plate 82. The connecting plate 82 is connected to a round rod 83 extending into the protective cover 5 on one side facing the protective cover 5, and the other end of the round rod 83 is connected to a stop plate 84 in the protective cover 5, and the stop plate 84 is close to the stop wheel 626. The connecting plate 82 is connected to a round rod 85 extending into the protective cover 5 on the other side facing the protective cover 5, and the other end of the round rod 85 is connected to an inclined plate 86 in the protective cover 5, and the inclined plate 86 is close to the stop wheel 624.

[0030] The above scheme is adopted: due to the operation of the electromagnetic telescopic rod 81, the round rod 1 83 and the inclined plate 86 can be driven to move toward the inside of the protective cover 5 through the connecting plate 82, and at the same time, the plate 84 and the inclined plate 86 are respectively moved to the top of the wheel 2 626 and the wheel 1 624. When the wheel 2 626 abuts against the plate 84, the wheel 2 626 can roll along the inclined surface of the plate 84, so that the wheel 2 626 is subjected to a squeezing force. When the wheel 1 624 abuts against the lower inclined surface of the round rod 2 85, the wheel 1 624 can roll along the inclined surface of the round rod 2 85, so that the wheel 1 624, the connecting rod 623 and the square rod 618 are subjected to a squeezing force.

[0031] like Fig.11 As shown, two salt spreading mechanisms 7 are also included, and the two salt spreading mechanisms 7 are respectively arranged on both sides of the shield 5. The salt spreading mechanism 7 includes a material box 71, and the material box 71 is installed on the shield 5. A top cover 72 is arranged on the material box 71. The bottom of the material box 71 is fixedly connected to a material guide bin 73 located inside the shield 5, and the bottom of the material guide bin 73 faces the vibration frame 610. A rotating wheel 74 that can be driven by a motor is movably installed inside the material guide bin 73, and a plurality of material troughs 75 are opened around the outside of the rotating wheel 74.

[0032] The above scheme is adopted: industrial salt is added to the inside of the material box 71 in advance, so that the industrial salt at the bottom of the material box 71 falls into the material trough 75. Before the vibration frame 610 descends, the motor drives the wheel 74 to rotate, and the industrial salt contained in the material box 71 can be discharged into the material guide bin 73 through the material trough 75, and then introduced into 314 inside 310 through the material guide bin 73.

[0033] like Fig.12 As shown, it also includes a heating mechanism 9, which is arranged on the outside of the protective cover 5. The heating mechanism 9 includes a water cylinder 91, which is installed on the protective cover 5. A heating plate 93 is installed at the lower part of the water cylinder 91, a water valve 92 is arranged on the top of the water cylinder 91, and a valve 94 is arranged on the upper part of the outside of the water cylinder 91. A connecting pipe 95 is connected to the valve 94, and the bottom end of the connecting pipe 95 is connected to the protective cover 5.

[0034] The above scheme is adopted: water is added to the inside of the water cylinder 91 in advance through the open water valve 92, and then the water valve 92 is closed. Under the heating effect of the heating plate 93, the water in the water cylinder 91 is heated to boil, and the valve 94 is opened to allow the boiling steam to be introduced into the protective cover 5 through the connecting pipe 95. When industrial salt is spread to dissolve the ice surface, the heat of the steam introduced into the protective cover 5 can be directly absorbed, thereby accelerating the melting of the ice surface.

[0035] The working principle and use process of the present invention: When in use, the cylinder 4 runs, driving the shield 5 to move downward as a whole, so that the bottom of the shield 5 abuts against the ice surface, and then the gate 10 is controlled to descend and abut against the ice surface, so that the gate 10 can close the inner side of the shield 5, and then the motor drives the fixed wheel 62 to rotate, and the suspension rope 65 is lowered through the movable wheel 64, so that the hanger 66 and the vibration frame 610 are lowered along the fixed block 67, so that the ice crusher 611 contacts the ice surface, and the vibration motor 613 is started. Due to the operation of the vibration motor 613, the vibration frame 610 can be driven to vibrate at a high frequency through the bracket 612, and the ice crusher 611 can hit the ice surface, and the high-frequency vibration is used to achieve the hitting of the ice surface. At the same time, the rubber buffer sleeve 68 and the rubber buffer block 69 can buffer the vibration of the hanger 66 and the fixed block 67. The motor drives the movable arm 63 and the movable wheel 64 to rotate downward a part, so that the suspension rope 65 is detached from the movable wheel 64, and the movable wheel 64 is contacted to limit the height of the vibration frame 610 through the suspension rope 65, so that the vibration frame 610 can hit the ice surface downward through the ice-breaking cone 611. After the ice-breaking cone 611 is inserted into the ice surface, the surface layer of the ice surface is broken, and then the operation of the vibration motor 613 is stopped. The motor controls the movable arm 63 and the movable wheel 64 to rotate and reset, so that the suspension rope 65 returns to the movable wheel 64, and the motor drives the fixed wheel 62 to rotate, and the vibration frame 610 is pulled up and reset through the suspension rope 65, so that the ice-breaking cone 611 is detached from the ice surface.

[0036] Industrial salt is added to the material box 71 in advance, so that the industrial salt at the bottom of the material box 71 falls into the material trough 75. Before the vibration frame 610 descends, the motor drives the wheel 74 to rotate, and the industrial salt contained in the material box 71 can be discharged into the guide bin 73 through the material trough 75, and then introduced into 314 inside 310 through the guide bin 73. After the vibration frame 610 descends, the vibration generated by the operation of the vibration motor 613 can also vibrate and spread the industrial salt on the swing blade 614, so that it is evenly distributed on the swing blade 614, and the industrial salt on the swing blade 614 is evenly distributed on the ice. After the cone 611 breaks the surface of the ice, when the vibration frame 610 is pulled upward by the rope 65 to reset, the operation of the electromagnetic telescopic rod 81 can drive the round rod 1 83 and the inclined plate 86 to move toward the inner side of the shield 5 through the connecting plate 82, and at the same time, the plate 84 and the inclined plate 86 move to the top of the wheel 2 626 and the wheel 1 624 respectively. As the vibration frame 610 rises, the wheel 2 626 can first contact with the plate 84 and roll along the inclined surface of the plate 84, so that the wheel 2 626 and the push rod 625 move toward the vibration frame 610. 0 pushes from the inner side, at this time, the tension spring 2 621 is stretched, and the clamping rod 627 is disengaged from the square rod 618, releasing the fixation of the square rod 618. Then, as the vibration frame 610 continues to rise, the wheel 1 624 abuts against the lower inclined surface of the round rod 2 85 and rolls along the inclined surface of the round rod 2 85, so that the connecting rod 623 and the square rod 618 move laterally along the mounting block 616. At this time, the rubber buffer sleeve 2 617 is stretched, and the movement of the rubber rack 619 can drive the meshing rubber gear 615 to drive the swing blade 614 flips downward, and when the pendulum blade 614 flips, the industrial salt on the pendulum blade 614 is sprinkled onto the broken ice surface to accelerate the melting of the ice surface. As the vibration frame 610 continues to rise, the connecting rod 623 can be preferentially detached from the inclined plate 86 and reset under the elastic recovery action of the tension spring 1 620, and then the second wheel 626 is detached from the plate 84, and the elastic recovery action of the second spring 621 drives the clamping rod 627 to reset and be connected to the square rod 618, and finally the electromagnetic telescopic rod 81 runs to drive the plate 84 and the inclined plate 86 to reset.

[0037] Water is added to the water cylinder 91 in advance through the opened water valve 92, and then the water valve 92 is closed. Under the heating effect of the heating plate 93, the water in the water cylinder 91 is heated to boil, and the valve 94 is opened to allow the boiling steam to be introduced into the protective cover 5 through the connecting pipe 95. When industrial salt is spread to dissolve the ice surface, the heat of the steam introduced into the protective cover 5 can be directly absorbed, thereby further accelerating the melting of the ice surface.

[0038] When the hardness of the ice surface drops to a level that is easy to break, the vibration frame 610 is further lowered to the ice layer through the suspension rope 65, and the vibration motor 613 is started to drive the vibration frame 610 and the ice crusher 611 to continue to hit the ice surface, thereby breaking the ice surface at the gate 10 and ensuring the normal lifting and lowering operation of the gate 10.
