Description

Technical Field

[0001] The present invention relates to the technical field of anti-icing for water conservancy and hydropower gates, and in particular to an anti-icing structure for water conservancy and hydropower gates. Background Art

[0002] Water conservancy and hydropower gates are core facilities used to control water flow in water conservancy projects. Their functions include water retaining, flow regulation, and flood discharge. They are widely used in reservoirs, channels, hydropower stations and other scenarios. In cold environments, channel gates often face the problem of water freezing. The ice layer not only causes the gate plates and gate slots to freeze and cannot be opened and closed normally, but the long-term static ice pressure generated by the expansion of the ice layer may also cause deformation or even damage to the gate structure.

[0003] In the existing technology, common anti-icing measures for channel gates usually include: laying electric heating devices on the gate surface or in the gate groove to melt ice, or continuously releasing compressed air through underwater pipes to create water flow disturbance to inhibit ice formation; in addition, for the ice layer that has formed, manual assistance is required to break the ice to restore the normal working condition of the gate.

[0004] However, the traditional anti-icing measures for channel gates have the following problems: 1. In the existing technology, although the electric heating ice melting device can alleviate the problem of gate freezing, when it heats the water body and ice layer through heat conduction of the electric heating wire, the heat energy transfer efficiency is significantly reduced due to the influence of water convection and heat loss of metal components, resulting in a slow ice melting speed and the range of action is limited to the area around the heating element. In addition, the heating state needs to be maintained after the ice melts to prevent the water surface from quickly condensing again due to low temperature, which further aggravates energy consumption; 2. In the existing technology, although compressed air disturbance can inhibit the freezing process through water flow movement, its mechanism of action is limited to preventive intervention in the unfrozen state. It can neither directly break the ice layer structure that has been formed, nor does it need to be started in advance before the cold wave arrives. In order to maintain the fluidity of the water body, energy consumption and equipment loss will increase simultaneously. If ice is formed due to extreme low temperature or system delay, manual ice breaking will still be required, which will not only greatly increase the overall labor cost, but also lead to safety risks in low-temperature environments. 3. In the existing technology, heating and ice-melting devices and underwater pipeline systems mostly adopt a fixed installation design. Although their functions are concentrated in the cold season, they are limited by the integration of gates and equipment structures. It is often difficult to disassemble and repair them efficiently during the non-use period, resulting in long-term exposure of heating and ice-melting devices or underwater pipeline systems to water corrosion, siltation and other environments. Due to delayed maintenance, their key components are easily aged or their functions are attenuated, which in turn affects the anti-icing effect of the gates in cold seasons. Summary of the Invention

Each group is composed of docking seats 321 that are symmetrical and open at the lower end. A straight slot 322 with an open upper end is provided on the upper surface of the docking seat 321. A straight card slot 323 connected up and down is provided at the lower end of the straight slot 322. The straight slot 322 and the straight card slot 323 are vertically distributed.

The lower surface of the positioning seat 331 is provided with a linear receiving groove 332 with an opening at the lower end and aligned with the corresponding linear slot 322.

[0031] See also Figure 1 、 Figure 2 and Figure 3 The plug-in portion 34 includes a movable rod 341 elastically arranged in a movable groove by a spring, a knob is fixedly provided on the upper side of the movable rod 341, a connecting rod movably connected to the corresponding through groove is fixedly provided on the lower side of the movable rod 341, and a linear clamping plate 342 is fixedly provided on the lower side of the connecting rod, which is plugged into and matched with the corresponding linear receiving groove 332, linear slot 322 and linear clamping groove 323.

[0032] When the U-shaped mounting platform 31 is to be installed on the front-to-back symmetrical U-shaped crossbeam 2, first place the U-shaped mounting platform 31 on the upper side of the front-to-back symmetrical U-shaped crossbeam 2, and align each positioning seat 331 on the U-shaped mounting platform 31 with the corresponding docking seat 321 on the corresponding U-shaped crossbeam 2. At this time, the linear groove 332 on the positioning seat 331 and the linear clamping plate 342 in the linear groove 332 are aligned with the linear slot 322 on the corresponding docking seat 321. The corresponding connecting rod and the linear clamping plate 342 are driven downward by the movable rod 341 to make the linear clamping plate 342 inserted downward into the corresponding linear slot 3 22, until the linear clamping plate 342 moves to the opening at the lower end of the corresponding docking seat 321, and then the movable rod 341 and the linear clamping plate 342 are rotated ninety degrees by the knob. At this time, the linear clamping plate 342 is aligned with the corresponding linear slot 323 above. Then release the movable rod 341, and under the elastic action of spring 1, the movable rod 341 drives the linear clamping plate 342 upward to be clamped into the corresponding linear slot 323, thereby stably positioning and fixing the positioning seat 331 and the corresponding docking seat 321, and the U-shaped mounting platform 31 is then quickly and stably installed on the front and rear symmetrical U-shaped beam 2.

[0033] When the U-shaped mounting platform 31 is to be removed from the U-shaped beam 2, first press the corresponding linear clip 342 downward by the movable rod 341 until the linear clip 342 moves into the opening at the lower end of the corresponding docking seat 321, and then drive the linear clip 342 to rotate ninety degrees again by the knob to align the linear clip 342 with the corresponding linear slot 322 above. At this time, release the movable rod 341, and under the elastic action of spring 1, the movable rod 341 drives the linear clip 342 to move upward and slide through the corresponding linear slot 322 to be inserted into the corresponding linear receiving groove 332 again, thereby releasing the fixation of the positioning seat 331 and the corresponding docking seat 321, and the U-shaped mounting platform 31 can be quickly removed from the U-shaped beam 2.

[0034] See also Figure 1 The ice-breaking mechanism 4 includes a slide 41 symmetrically mounted on a U-shaped mounting platform 31. The U-shaped mounting platform 31 is symmetrically provided with a lifting buffer part 42 corresponding to the slide 41 and used for free fall and elastic buffering. A positioning air injection part 43 is commonly provided on the lower side of the left and right symmetrical lifting buffer parts 42. A lifting ice-breaking part 44 for breaking the ice layer is provided on the lower side of the positioning air injection part 43.

[0035] See also Figure 1 and Figure 2 The lifting buffer part 42 includes a socket 421 fixedly set on the lower side of the U-shaped mounting platform 31, and a socket 1 that passes through the front and back is provided on the socket 421. A sliding rod 422 that moves up and down is slidably provided on the slide 41, and a socket 2 that passes through the front and back is provided at the lower end of the slide rod 422. The socket 2 is positioned and plugged with the corresponding socket 1 through a pin, and a buffer plate 423 that is slidably connected to the corresponding slide rod 422 is elastically connected to the upper side of the slide 41 through a spring 2.

[0036] First, the latches in the corresponding sockets 1 and 2 are released to release the lock of the slide bar 422 and the corresponding socket 421, so that the slide bar 422 slides downward along the slide seat 41 under the action of gravity until the upper end of the slide bar 422 comes into contact with the upper surface of the buffer plate 423. Under the action of inertia, the slide bar 422 then drives the buffer plate 423 to move downward and compress the corresponding spring 2. The spring 2 then decelerates and buffers the downward moving slide bar 422 and the buffer plate 423 through its own deformation to avoid direct collision between the slide bar 422 and the buffer plate 423 and the slide seat 41, until, under the elastic action of the spring 2, the slide bar 422 and the corresponding buffer plate 423 gradually reach a balanced state with the spring 2 and no longer move back and forth.

[0037] See also Figure 1 and Figure 4The aligned gas injection portion 43 includes a gas injection bin 431 fixedly arranged on the lower side of the left and right symmetrical sliding rods 422. A plurality of docking bins 432 are uniformly rotated left and right on the gas injection bin 431. A plurality of air inlet holes connected to the interior of the gas injection bin 431 are uniformly opened circumferentially on the side surface of the docking bin 432. A connecting pipe 433 connected up and down is fixedly arranged on the lower side of the docking bin 432.

[0038] See also Figure 1 and Figure 4 The lifting ice-breaking part 44 includes an ice-breaking cone 441 fixedly arranged on the lower side of the connecting pipe 433. An air groove connected to the corresponding connecting pipe 433 is opened in the ice-breaking cone 441. A plurality of air outlet holes connected inside and outside are evenly opened on the ice-breaking cone 441 in a circumferential direction. A plurality of blades 442 that are wide at the top and narrow at the bottom are evenly fixed on the outer side of the ice-breaking cone 441 in a circumferential direction.

[0039] When the ice layer near the gate body 1 is to be broken, the locks of the left and right symmetrical slide bars 422 and the corresponding sockets 421 are first released at the same time. Under the action of their own weight, the left and right symmetrical slide bars 422 and their corresponding air injection bins 431 move downward, and the docking bin 432 on the air injection bin 431 and the connecting pipe 433 and the ice-breaking cone 441 on the lower side also fall freely synchronously. Under the support of gravitational potential energy, the ice-breaking cone 441 quickly breaks the ice layer near the gate body 1 through the cone surface at the lower end and completely submerges into the water below the ice layer. At the same time, under the buffering action of the buffer plate 423 and the second spring, the slide bar 422 drives the corresponding ice-breaking cone 441 makes a certain number of up and down reciprocating movements, and the blades 442 on the outside of the ice-breaking cone 441 then drive the ice-breaking cone 441 and the docking chamber 432 at the upper end of the corresponding connecting pipe 433 to rotate under the action of the water flow above, so that the ice-breaking cone 441 and the blades 442 repeatedly stir the surrounding water and the broken ice layer to expand the range of breaking the ice layer and inhibit the condensation of the surrounding water body. The narrow lower part of the blade 442 can reduce the resistance of the ice-breaking cone 441 to fall and break the ice layer, thereby ensuring the impact force of the ice-breaking cone 441 on the ice layer. At the same time, the wide upper part of the blade 442 can ensure stable cooperation with the water flow to drive the ice-breaking cone 441 to rotate and stir.

[0040] See also Figure 1 The disturbance mechanism 5 includes a fixed-length winding portion 51 and a winding driving portion 52 for driving the fixed-length winding portion 51, which are arranged on the upper side of the right U-shaped mounting platform 31 and are used to lift the lifting and ice-breaking portion 44. A positive-pressure air injection portion 53 is provided on the upper side of the left U-shaped mounting platform 31 to cooperate with the positioning air injection portion 43 to inject compressed air into the lifting and ice-breaking portion 44.

[0041] See also Figure 1 、 Figure 4 and Figure 5The fixed-length winding portion 51 includes a winding drum 511 which is symmetrically rotated front and back through a U-shaped support and is arranged on the upper side of the right U-shaped mounting platform 31. A driven wheel 512 which is rotatably connected to the corresponding U-shaped support is fixed between the front and rear symmetrical winding drums 511 through a connecting shaft. A winding cable 513 is installed on the winding drum 511, and a ring that moves up and down is slidably connected to the connecting pipe 433 in the middle of the same side, and the ring is fixedly connected to the lower end of the corresponding winding cable 513.

[0042] See also Figure 1 and Figure 5 The winding drive unit 52 includes a motor 521 mounted on the upper side of the right U-shaped mounting platform 31 through a fixed support. A driving wheel 522 is fixedly provided at the driving end of the motor 521, and the driving wheel 522 is connected to the driven wheel 512 through a belt drive.

[0043] When the ice-breaking cone 441 that is stably submerged in the water below the ice layer is to be pulled up and out of the water, the motor 521 drives the driving wheel 522 to rotate in a directional manner, and the driving wheel 522 then drives the driven wheel 512 to rotate synchronously through the belt, and the driven wheel 512 then drives the front and rear symmetrical winding drum 511 to rotate synchronously through the connecting shaft to wind the corresponding winding cable 513, and the winding cable 513 then drives the corresponding connecting pipe 433 and its corresponding air injection chamber 431 to move upward through the ring, and the ice-breaking cone 441 corresponding to the lower side of the air injection chamber 431 moves upward synchronously. Under the action of the water, the blade 442 then drives the ice-breaking cone 441 to rotate and stir synchronously until the ice-breaking cone 441 is completely pulled up and out of the water; in the process of the connecting pipe 433 freely falling downward, the corresponding connecting pipe 433 and the corresponding ring will slide relative to each other until the connecting pipe 433 tends to be balanced under the buffering action of spring 2.

[0044] See also Figure 1 、 Figure 4 and Figure 5 The positive pressure gas injection part 53 includes an air cylinder 531 which is symmetrically installed on the upper side of the left U-shaped mounting platform 31 through the fixed platform. A flexible air injection tube 532 that passes through the upper and lower parts is installed at the lower end of the air cylinder 531. The lower end of the flexible air injection tube 532 is installed on the upper side of the air injection warehouse 431 on the same side. The air cylinder 531 is connected to the air injection warehouse 431 on the same side through the corresponding flexible air injection tube 532. A piston rod 533 that moves up and down is slidingly provided in the air cylinder 531. A piston plate is fixedly provided at the lower end of the piston rod 533. A connecting plate is fixedly provided at the upper ends of the front and rear symmetrical piston rods 533. An electric push rod 534 is installed on the upper side of the fixed platform. The telescopic end of the electric push rod 534 is fixedly connected to the lower side of the connecting plate.

[0045] When the ice breaker cone 441 breaks the ice layer and is stably immersed in the water body, the electric push rod 534 first drives the connecting plate to move downward, and the connecting plate then drives the piston rod 533 and its corresponding piston plate to move downward along the corresponding air cylinder 531. The air in the air cylinder 531 is then injected into the corresponding air injection bin 431 through the corresponding flexible air injection pipe 532, and the compressed air is then injected from the air injection bin 431 into the corresponding docking bin 432 through the air inlet hole, and then injected into the air groove in the corresponding ice breaker cone 441 through the connecting pipe 433, and finally input into the water body through the air outlet to continuously disturb the water body, thereby preventing the water body from condensing again.

[0046] Before the air in the air cylinder 531 is exhausted, the motor 521 drives the cable 513 again to pull the ice breaker cone 441 out of the water. At this time, the electric push rod 534 can drive the piston rod 533 and the piston plate to move upward along the corresponding air cylinder 531, and the air is then reversely sucked into the air cylinder 531 through the air outlet. Then, the motor 521 drives the cable 513 to drive the ice breaker cone 441 to move downward and return to the water body. At this time, the electric push rod 534 can be used to synchronously output the air from the air outlet to the water body, so that the water body is alternately disturbed by the physical disturbance of the ice breaker cone 441 and the disturbance of compressed air, so as to ensure the anti-icing effect of the water body around the gate body 1.

[0047] The above-mentioned operation method can not only realize the breaking of the ice layer by the free-falling impact of the ice-breaking cone 441, but also stir the surrounding water body by intermittently lifting the ice-breaking cone 441 to expand the ice-breaking range. At the same time, after breaking the ice, the compressed air flow is intermittently released to disturb the water body to inhibit the water surface from condensing again. Therefore, under the premise of ensuring the anti-icing effect of the gate, it avoids the energy waste caused by advance air supply and reduces the frequency of pulling the ice-breaking device, significantly reducing the overall energy consumption of the anti-icing operation and optimizing the energy utilization efficiency. Therefore, it not only avoids the local limitations and heat loss problems of traditional heating ice melting, but also replaces manual ice breaking by automated impact, avoiding the safety hazards of low-temperature environment operations.

[0048] The ice-breaking mechanism 4 and the disturbance mechanism 5 can be quickly disassembled from the gate body 1 by quickly disassembling the U-shaped mounting platform 31, so as to realize convenient installation and separation of the ice-breaking mechanism 4 and the disturbance mechanism 5, thereby realizing rapid disassembly and centralized maintenance or storage of the ice-breaking mechanism 4 and the disturbance mechanism 5 during the non-use period, effectively avoiding the risk of continuous damage to the mechanism components caused by silt accumulation, metal corrosion, etc. due to long-term underwater fixed installation, thereby significantly improving the reliability and maintenance efficiency of the ice-breaking mechanism 4 and the disturbance mechanism 5 throughout their life cycle while reducing the seasonal idle loss of the ice-breaking mechanism 4 and the disturbance mechanism 5.

[0049] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
