Description

Technical Field

[0001] The present invention relates to the technical field of canal gates, and in particular to a canal gate antifreeze device. Background Art

[0002] Canal gates are an important part of water conservancy projects. They are mainly used to control the direction, speed and flow of water. Canal gates are usually installed at key positions in the canal to achieve effective management and utilization of water resources. Common ones include flat gates, radial gates, flap gates, etc. Flat gates consist of a flat plate and a frame surrounding the plate. They are usually installed vertically in channels and rivers, and are opened and closed by lifting.

[0003] Current anti-freezing measures for flat gates usually use electric heating and mechanical ice-breaking methods. The electric heating method refers to installing an electric heating device or a hot water circulation system on the gate to keep the water temperature above the freezing point to prevent freezing; the ice-breaking method refers to breaking the ice layer formed in front of the gate by manual chiseling or mechanical equipment to ensure that the gate can be opened and closed normally; however, the electric heating method requires continuous power supply for heating, and since the change in water level cannot be determined, the entire gate needs to be heated, which consumes a lot of electricity and is not conducive to energy conservation; secondly, when using the ice-breaking method, the ice layer is tightly adhered to the gate and the mechanical impact force is large, which will cause the local pressure on the surface where the gate and the ice layer are connected to be too high, which will lead to violent ice breaking and damage to the surface of the gate; thirdly, it is difficult to deal with the gap between the gate and the frame when breaking the ice. Opening the gate when it is not fully thawed will cause the sealing strip between the gate and the frame to be damaged, which will affect the sealing of the gate.

[0004] Therefore, in order to save electric energy and avoid damage to the gate surface caused by violent ice breaking, the present invention provides a canal gate antifreeze device. Summary of the Invention

[0013] In the above-mentioned antifreeze device for the canal gate, the water delivery mechanism includes a water storage tank, and the water storage tank is detachably mounted on the support frame, the middle part of the bottom wall of the float plate is fixedly connected to a traction rod which is slidably connected to the top wall of the water storage tank, and the bottom wall of the traction rod is fixedly connected to a rubber plug which is slidably connected to the inside of the water storage tank.

The water delivery component includes a water delivery tank, and the water delivery tank is fixedly connected to the middle part of the bottom wall of the water storage tank. The interior of the water delivery tank is fixedly connected to a fixing frame, and the fixing frame and the inner wall of the water delivery tank are in a non-sealed state.

[0015] In the above-mentioned antifreeze device for a canal gate, the top wall of the fixed frame is connected to a rubber plug 2 through a spring, and a hole with a diameter smaller than that of the rubber plug 2 is opened in the middle of the bottom wall of the water storage tank.

[0019] 2. Through the cooperation of ice-breaking components and buffer parts, the ice-breaking blades move upward against the side wall of the gate to push the ice layer between the two adjacent floating plates. The staggered operation of multiple ice-breaking blades can disperse the impact force; multiple lower ice-breaking edges and corresponding upper ice-breaking edges cooperate to squeeze the ice layer from the upper and lower directions to break the large area of ​​ice into multiple small ice cubes, avoiding excessive local pressure on the surface connecting the gate and the ice layer, and also accelerating the melting of the ice surface.

[0020] 3. Through the coordination of the thawing mechanism, ice-breaking mechanism and water-delivering mechanism, the water-delivering mechanism extracts and outputs water from under the ice layer, and melts the water through the first and second water outlet heads; the first water outlet head performs auxiliary water-flowing melting treatment on the contact part between the corresponding inverted L-shaped plate and the gate, and the second water outlet head performs auxiliary water-flowing melting treatment on the sealing strip at the connection between the gate and the support frame. Targeted thawing of the sealing strip can prevent the damage of the sealing strip caused by the violent separation of the support frame and the gate when the gate is opened, which in turn leads to a deterioration of the sealing between the support frame and the gate.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 2 A canal gate antifreeze device is installed on the canal gate 1. The canal gate 1 includes a support frame 11. The inner wall of the support frame 11 is symmetrically provided with slide rails 12. The two slide rails 12 are connected to the gate 13 by sliding up and down together through a sealing strip 14. The top wall of the gate 13 is rotated with a push rod 15 threadedly connected to the support frame 11.

[0035] Reference Figure 1 A thawing mechanism 2 is provided on the support frame 11, a plurality of hydraulic rods 3 are installed on the thawing mechanism 2, an ice-breaking mechanism 4 is provided on the hydraulic rods 3, and a water supply mechanism 5 is provided on the thawing mechanism 2 and the ice-breaking mechanism 4.

[0036] The push rod 15 is driven to rotate by an existing driving method (such as an external motor and a gear box. The gear box is an existing mature technology and will not be described in detail here). The push rod 15 is threadedly connected to the support frame 11. The push rod 15 drives the gate 13 to slide up and down relative to the support frame 11. When the gate 13 moves to the lower part of the support frame 11, it is in a closed state. When the gate 13 moves to the upper part of the support frame 11, it is in an open state. The sealing strip 14 increases the sealing performance of the connection between the gate 13 and the support frame 11.

[0037] When the gate 13 is in the closed state, the thawing mechanism 2 rises as the water level rises and falls as the water level drops. In winter, the water surface freezes. Before opening the gate, the thawing mechanism 2 and the water supply mechanism 5 cooperate to thaw the space between the gate 13 and the ice layer. The hydraulic rod 3 drives the thawing mechanism 2 and the ice-breaking mechanism 4 to cooperate in breaking the ice. When the ice surface is broken, the gate is opened.

[0038] Reference Figure 1 and Figure 3 The thawing mechanism 2 includes two guide rods 21 symmetrically fixed on the support frame 11 in a vertical direction. The guide rods 21 are provided with a heating and thawing component 22 for preheating and thawing the flat ice area. The heating and thawing component 22 is provided with a flowing water thawing component 23 for accelerating the thawing of the flat ice area and the connecting gap.

[0039] Reference Figure 3 、 Figure 5 and Figure 6 The heating and thawing component 22 includes a floating plate 221, and the two guide rods 21 are connected to the floating plate 221 for sliding up and down. A plurality of inverted L-shaped plates 222 are evenly fixedly connected from left to right on the side of the floating plate 221 close to the gate 13. A heating wire 223 is installed in series inside the outer periphery of the floating plate 221 and inside the plurality of inverted L-shaped plates 222.

[0040] Reference Figure 1 、 Figure 3 、 Figure 5 and Figure 7 The flowing water thawing assembly 23 includes a support frame 231, the top wall of the floating plate 221 is fixedly connected to the support frame 231, and a plurality of water outlet heads 232 corresponding to the upper and lower parts of the inverted L-shaped plate 222 are evenly installed from left to right on the side of the inverted L-shaped plate 222 close to the gate 13. The support frame 231 is installed with a plurality of water outlet heads 233 aligned with the sealing strip 14 at the connection between the support frame 11 and the gate 13 at the left and right ends.

[0041] Reference Figure 1 and Figure 3 The ice-breaking mechanism 4 includes a support bracket 41 jointly arranged at the bottom of the hydraulic rod 3, an ice-breaking component 42 arranged on the support bracket 41 for breaking ice on the surface of the gate 13, and a buffer member 43 arranged on the support bracket 41 and the heating and thawing component 22 for absorbing part of the impact force during ice breaking.

[0042] Reference Figure 3 、 Figure 4 、 Figure 8 and Figure 9Two hydraulic rods 3 distributed front and back are installed on the left and right sides of the floating plate 221, and the bottom walls of the output ends of the four hydraulic rods 3 are fixedly connected to the support bracket 41. The ice-breaking assembly 42 includes an ice-breaking knife 421, and the top wall of the support bracket 41 is fixedly connected to a plurality of ice-breaking knives 421 staggered left and right with the inverted L-shaped plate 222; the bottom wall of the floating plate 221 is evenly fixedly connected with a plurality of upper ice-breaking ridges 423 from left to right, and the top wall of the support bracket 41 is fixedly connected with a plurality of lower ice-breaking ridges 422 corresponding to the upper and lower ice-breaking ridges 423. A plurality of buffers 43 are installed on the side of the support bracket 41 and the floating plate 221 close to the gate 13. The buffer 43 consists of a spring rod installed on the side walls of the support bracket 41 and the floating plate 221 and a ball rolling on the end of the spring rod, and the side wall of the ball is in contact with the side wall of the gate 13.

[0043] The floating plate 221 floats on the water surface and rises or falls with the change of water level. The floating plate 221 drives the hydraulic rod 3 and the ice-breaking mechanism 4 to move. The floating plate 221 of appropriate size can be selected according to actual needs, so that the ice-breaking mechanism 4 is always close to the ice layer on the water surface, which saves adjustment time and can quickly and accurately position and perform ice breaking.

[0044] The hydraulic rod 3 is an existing low-temperature resistant and waterproof hydraulic rod. In order to extend its service life, a telescopic protective cover can be installed on the outside of the hydraulic rod 3 between the floating plate 221 and the supporting bracket 41. The inverted L-shaped plate 222 is attached to the side wall of the gate 13. Before opening the gate, the heating wire 223 is energized, the surface temperature of the inverted L-shaped plate 222 increases, and part of the ice between the inverted L-shaped plate 222 and the gate 13 melts due to the heat. The bottom wall of the output end of the hydraulic rod 3 moves upward, driving the supporting bracket 41 to move upward as a whole, and the supporting bracket 41 drives the ice-breaking knife 421 to move between the corresponding two adjacent inverted L-shaped plates 222. The ice-breaking knife 421 moves upward closely against the side wall of the gate 13 to push the ice layer between the two adjacent inverted L-shaped plates 222. Multiple ice-breaking knives 421 work in an interlaced manner to disperse the impact force. The heat melts the ice layer at the edge of the inverted L-shaped plate 222 to assist the ice layer to quickly separate, preventing the ice layer from adhering to the gate 13 and causing violent ice breaking, which damages the surface of the gate 13.

[0045] At the same time, the lower ice-breaking ridges 422 move upward and approach the upper ice-breaking ridges 423. Multiple lower ice-breaking ridges 422 and corresponding upper ice-breaking ridges 423 cooperate to squeeze the ice layer from the upper and lower directions to break the large area of ​​ice into multiple small ice cubes, avoiding excessive local pressure on the surface where the gate 13 connects to the ice layer, and also accelerating the melting of the ice surface.

[0046] When the support bracket 41 moves upward to perform ice-breaking operations, the vibrations generated by the gate 13, the support bracket 41 and the floating plate 221 during the ice-breaking process are buffered by the buffer 43. The balls of the buffer 43 roll on the side wall in contact with the gate 13, and the telescopic end of the buffer 43 slides on the fixed end to buffer the vibrations between the gate 13 and the support bracket 41, and the gate 13 and the floating plate 221 when breaking the ice layer, so as to absorb part of the impact force and reduce damage to the surface of the gate 13.

[0047] The hydraulic rod 3 drives the ice-breaking mechanism 4 to move up and down and back and forth multiple times to perform ice-breaking operations.

[0048] Reference Figure 1 and Figure 10 The water supply mechanism 5 includes a water storage tank 51, and the water storage tank 51 is detachably mounted on the support frame 41. A traction rod 52 is fixedly connected to the middle of the bottom wall of the floating plate 221 and is slidably connected to the top wall of the water storage tank 51. The bottom wall of the traction rod 52 is fixedly connected to a rubber plug 53 that is slidably connected to the inside of the water storage tank 51. A water supply component 54 and a water absorption component 55 are commonly provided on the water storage tank 51 and the rubber plug 53.

[0049] Reference Figure 1 、 Figure 7 and Figure 10 The water supply assembly 54 includes a water supply tank 541, which is fixedly connected to the water supply tank 541 in the middle of the bottom wall of the water storage tank 51, and a fixing frame 542 is fixedly connected to the inside of the water supply tank 541, and the fixing frame 542 and the inner wall of the water supply tank 541 are in a non-sealed state; the top wall of the fixing frame 542 is connected to the rubber plug 2 543 through a spring, and a hole with a diameter smaller than the rubber plug 2 543 is opened in the middle of the bottom wall of the water storage tank 51, and a spring rod 1 544 is fixedly connected to the middle of the bottom wall of the rubber plug 1 53. The bottom wall of the water supply tank 541 is connected to the water outlet head 1 232 and the water outlet head 2 233 through a flexible pipe, and the outer wall of the flexible pipe is wrapped with the heating wire 234.

[0050] Reference Figure 10 The water absorption component 55 includes a water inlet bin 551. The bottom wall of the water storage bin 51 is symmetrically fixed with the water delivery bin 541 as the center, and the water inlet bin 551 is connected therethrough. The side wall of the water inlet bin 551 located inside the water storage bin 51 is symmetrically provided with water inlets 552; the bottom wall of the rubber plug 1 53 is symmetrically fixed with the spring rod 1 544 as the center, and the bottom wall of the spring rod 2 553 is fixedly connected with the rubber plug 3 554 which is slidably connected to the inside of the water inlet bin 551 up and down. A filter is installed on the bottom wall of the water inlet bin 551.

[0051] The support bracket 41 drives the traction rod 52 to move up and down in the water storage bin 51 , and the traction rod 52 drives the rubber plug 1 53 to slide up and down in the water storage bin 51 , and the rubber plug 1 53 drives the spring rod 1 544 and the spring rod 2 553 to move up and down.

[0052] When the rubber plug 53 moves downward, the spring rod 1 544 pushes the rubber plug 2 543 downward, the spring is compressed, and the rubber plug 2 543 moves away from the hole in the middle of the bottom wall of the water storage tank 51. The top of the water delivery tank 541 changes from a relatively closed state to an open state. At the same time, the spring rod 2 553 moves downward, driving the rubber plug 3 554 to slide downward inside the water inlet tank 551 until the bottom wall of the rubber plug 3 554 blocks the filter screen at the bottom of the water inlet tank 551. The bottom of the water inlet tank 551 changes from an open state to a relatively closed state. The telescopic sections of the spring rod 1 544 and the spring rod 2 553 shrink into the fixed section to adapt to the movement of the rubber plug 1 53. At this time, the rubber plug 1 53 pushes the water inside the water storage tank 51 through the hole in the bottom wall of the water storage tank 51, the water delivery tank 541 and the pipeline, and finally flows out from the water outlet 1 232 and the water outlet 2 233.

[0053] The heating wire 234 heats the water flowing in the pipe, and the water outlet head 1 232 and the water outlet head 2 233 flow out the water with increased temperature. The water outlet head 1 232 performs auxiliary water flow melting treatment on the corresponding inverted L-shaped plate 222 and the gate 13 at the bottom, and the water outlet head 233 performs auxiliary water flow melting treatment on the sealing strip 14 at the connection between the gate 13 and the support frame 11. The targeted thawing of the sealing strip 14 can prevent the support frame 11 and the gate 13 from being forcibly separated when the gate is opened, which may cause damage to the sealing strip 14, and further lead to deterioration of the sealing between the support frame 11 and the gate 13.

[0054] When the rubber plug 1 53 moves up, the spring rod 1 544 releases the push on the rubber plug 2 543, and the spring drives the rubber plug 2 543 to reset. The rubber plug 2 543 blocks the hole at the bottom of the water storage bin 51, and the top of the water delivery bin 541 changes from an open state to a relatively closed state. At the same time, the spring rod 2 553 moves up and drives the rubber plug 3 554 to move up. The rubber plug 3 554 no longer blocks the filter screen at the bottom of the water inlet bin 551, and the rubber plug 3 554 moves to the top of the water inlet bin 551. The bottom of 51 changes from a relatively closed state to an open state, and the telescopic sections of spring rod 1 544 and spring rod 2 553 extend from the inside of the fixed section to adapt to the movement of rubber plug 1 53. At this time, rubber plug 1 53 moves upward to form a negative pressure inside the water storage tank 51, and water under the surface of the ice layer enters the water storage tank 51 through the water inlet tank 551 and the water inlet 552. In the process of reciprocating ice breaking, water is extracted and output reciprocally, and the water is melted by the water outlet head 1 232 and the water outlet head 2 233.

[0055] After the ice-breaking operation is repeated several times, the gate is opened. A variety of de-icing methods are used to respectively break the ice layer in a large area and thaw in a targeted manner to prevent the gate 13 from being frozen. There is no need to power on for a long time, which is highly efficient and energy-saving.

[0056] The specific operating steps of the canal gate antifreeze device are as follows: when the gate 13 is in the closed state, the floating plate 221 rises or falls with the change of the water level, and the floating plate 221 drives the ice breaking mechanism 4 to move, quickly and accurately positioning and performing ice breaking processing.

[0057] Before opening the gate, heating wire 1 223 and heating wire 2 234 are energized, and part of the ice layer between the inverted L-shaped plate 222 and the gate 13 is melted by the heat to assist the ice layer to quickly detach. The hydraulic rod 3 drives the support bracket 41 to drive multiple ice-breaking knives 421 to work in an interlaced manner, pushing the ice layer close to the side wall of the gate 13. At the same time, multiple lower ice-breaking edges 422 and corresponding upper ice-breaking edges 423 cooperate to squeeze the ice layer from the upper and lower directions, breaking the large area of ​​ice into multiple small ice cubes. The buffer 43 absorbs part of the impact force to reduce damage to the surface of the gate 13.

[0058] At the same time, the support bracket 41 drives the traction rod 52 and the rubber plug 1 53 to move up and down, and sends the water under the ice layer to the water outlet head 1 232 and the water outlet head 2 233. The heating wire 234 heats the water flowing in the pipeline. The water outlet head 1 232 assists in melting the flowing water at the corresponding inverted L-shaped plate 222 and the gate 13 at the bottom. The water outlet head 233 assists in melting the sealing strip 14 at the connection between the gate 13 and the support frame 11, and performs targeted thawing on the sealing strip 14.

[0059] When the gate is opened, the push rod 15 drives the gate 13 to slide up and down relative to the support frame 11 through the existing driving method, and the gate 13 is moved to the upper part of the support frame 11 to open the gate.

[0060] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
