Description

Technical Field

[0001] This invention belongs to the field of ice breaking in water conveyance channels, and specifically relates to an ice breaking and melting device for water conveyance channels. Background Technology

[0002] To reduce the amount of floating ice entering water conveyance channels during winter, ice-blocking cable structures are typically installed. These cables are also used to control the location and volume of ice jams. However, traditional ice-blocking cable structures usually consist of steel wire ropes fixed at both ends of the channel, with logs or metal beams connecting them to form a mesh structure. Due to limitations in the materials and fixing methods of the steel wire ropes and logs, these methods are not durable and stable enough, making them extremely susceptible to damage from ice impacts. When breaking ice, the ice depth in water conveyance channels is typically around 5 centimeters. Traditional icebreakers for water conveyance channels usually consist of a rod with a blade, typically a sharp metal sheet. For large areas of ice, traditional icebreakers are inefficient, difficult to clear quickly, and produce large chunks of ice that are unsuitable for removal.

[0003] Furthermore, the traditional method of melting ice involves spraying hot water directly onto the surface of the broken ice without removing the ice fragments from the water. This not only affects the melting efficiency but also causes the melted ice to refreeze, leading to the formation of new ice layers and increasing the difficulty of the cleanup work. Another traditional method involves clearing the broken ice directly from the river surface before melting, but this is more labor-intensive. Summary of the Invention

[0004] To address the aforementioned defects and problems, this invention provides an ice-breaking and melting device for water conveyance channels.

[0005] The solution adopted by this invention to solve its technical problem is: an ice-breaking and melting device for water conveyance channels, comprising a longitudinal transmission mechanism, a transverse transmission mechanism, an ice-breaking mechanism, and a winding and melting mechanism. The longitudinal transmission mechanisms are symmetrically installed on the riverbanks on both sides of the water surface. The transverse transmission mechanism is vertically arranged between the two longitudinal transmission mechanisms and is controlled by the longitudinal transmission mechanisms to slide back and forth along the water flow direction. The ice-breaking mechanism is fixedly installed on the nut seat of the transverse transmission mechanism. The ice-breaking mechanism includes a drive group, which includes an ice-breaking blade fixedly connected by a vertical rod. The ice-breaking blade performs up-and-down cutting motion on the ice surface. The longitudinal transmission mechanism... Downstream of the facility, there is also a winding and melting mechanism, which includes a water supply mechanism, a netting assembly, and a winding mechanism. The netting assembly is set perpendicular to the river surface and includes a rope net body and a flipping guide rod assembly. The water supply mechanism is connected to a water spray pipe horizontally set at the top of the rope net body. The winding mechanism is fixedly connected to the flipping guide rod assemblies on the left and right sides of the rope net body through traction ropes. In the natural state, after the ice is broken by the ice-breaking mechanism, the winding mechanism controls the flipping guide rod assembly to flip the rope net body from a vertical position upward to scoop up the broken ice above the water surface. Then, hot water is sprayed onto the broken ice held by the water spray pipe to melt the ice.

[0006] Furthermore, the longitudinal transmission mechanism includes a mounting frame, in which a longitudinal guide rail is fixedly installed along the water flow direction. Bearing seats are fixed on the inner bases at the front and rear ends of the longitudinal guide rail, and a rotating shaft is fitted inside each bearing seat. A sprocket is fitted on the end of each rotating shaft away from the bearing seat, and a chain is driven on the sprocket. A drive motor is connected to one of the rotating shafts. A longitudinal slider is also slidably installed on the longitudinal guide rail, and one side of the longitudinal slider is fixedly connected to the chain.

[0007] Furthermore, the transverse transmission mechanism includes a support base, transverse guide rails, a lead screw, a nut seat, and a transverse slider. The left and right ends of the support base are fixedly connected to the longitudinal slider of the longitudinal transmission mechanism. The upper surface of the support base is provided with transverse guide rails at intervals. A transverse slider is slidably installed on each transverse guide rail. A nut seat is fixedly installed at the top of each transverse slider. A transmission lead screw is fitted inside the nut seat. The left and right ends of the lead screw are rotatably installed with fixed seats on the longitudinal slider, and one end is connected to a motor.

[0008] Furthermore, the ice-breaking mechanism also includes a motor, an eccentric wheel bearing, and an eccentric wheel. The motor is fixedly mounted on the top surface of the nut seat via a motor mount. The motor output shaft is driven by the eccentric wheel bearing seat and connected to the eccentric wheel. A vertical rod is rotatably connected to the eccentric wheel, and the bottom of the vertical rod extends downward to connect with the connecting seat on the ice-breaking blade.

[0009] Furthermore, the icebreaker includes triangular pyramid-shaped blades evenly distributed at the bottom, with a thin blade at the bottom and arc-shaped ends at both ends, and the blades are arranged in a grid pattern.

[0010] Furthermore, the water delivery mechanism includes a water collection well, a high-pressure pump, a water delivery pipe, and a water spray pipe. The input end of the high-pressure pump is connected to the water collection well through a pipe, and the output water volume is adjusted by a valve on the pipe. The water collection well contains constant-temperature hot water, and the output end of the high-pressure pump is connected to the water spray pipe through the water delivery pipe. The water spray pipe is evenly provided with spray holes.

[0011] Furthermore, the flipping guide rod assembly includes a fixed guide rod a, a fixed guide rod b, and a support rod. The top of the fixed guide rod a is fixedly connected to the water spray pipe, and the bottom of the fixed guide rod b is hinged to it. The bottoms of the fixed guide rods b on the left and right sides are fixedly connected by the support rods. The support rods are fixed to the bottom of the rope net body.

[0012] Furthermore, the winding mechanism includes a winch motor and a winch. One end of the traction rope is fixedly connected to the bottom of the fixed guide rod b, and the other end is wound around the winch. The winch is driven by a winch motor installed in the mounting base.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] High-efficiency ice breaking: The rotation of the eccentric wheel driven by the motor drives the ice-breaking blade to move up and down in a reciprocating cutting motion, which can efficiently break ice and speed up the flow of water.

[0015] Automatic control: By setting up longitudinal and transverse transmission mechanisms, the longitudinal and transverse transmission of the icebreaker blade can be automatically controlled, making the icebreaking process more precise and efficient.

[0016] Energy-saving and environmentally friendly: Hot water is sprayed onto the ice fragments in the rope net body using a water spray pipe to melt the ice. Compared with traditional mechanical ice-breaking methods, this can save energy and reduce environmental pollution.

[0017] Safe and reliable: By controlling the flipping guide rod assembly of the nylon rope net, the nylon rope net is flipped upward, which can lift the floating ice on the ice surface to above the water surface. After the ice block is lifted out of the water surface, it is exposed to the air and receives more heat, which can accelerate the melting speed of the ice block.

[0018] Reduce the impact of ice on the water surface: Lifting the ice block off the water surface can reduce its obstruction of the water surface.

[0019] Improve heat exchange efficiency: When the ice block is lifted off the water surface, heat is more easily conducted into the ice block during heat exchange, thus melting the ice block more effectively.

[0020] To prevent refreezing: Lifting the ice block off the water surface and allowing heat exchange can prevent it from refreezing and ensure that the water remains unobstructed. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please see Figure 1-7 This invention provides a technical solution for an ice-breaking and melting device for water conveyance channels: Example

[0031] This embodiment provides an ice-breaking and melting device for water conveyance channels, including a longitudinal transmission mechanism, a transverse transmission mechanism 10, an ice-breaking mechanism 11, and a winding and melting mechanism. The longitudinal transmission mechanism is symmetrically installed on the riverbanks on both sides of the water surface, and the transverse transmission mechanism is vertically arranged between the two longitudinal transmission mechanisms and its forward and backward sliding is controlled by the longitudinal transmission mechanism.

[0032] Furthermore, such as Figure 1 As shown, the longitudinal transmission mechanism includes a mounting frame 1, within which a longitudinal guide rail 2 is fixedly mounted along the water flow direction. Bearing seats 5 are fixed to the inner base 6 at both ends of the longitudinal guide rail. A rotating shaft 7 is fitted into each bearing seat. A sprocket 9 is fitted onto the end of each rotating shaft furthest from the bearing seat. A chain 8 is mounted on the sprocket, and a drive motor is connected to one of the rotating shafts. A longitudinal slider 3 is also slidably mounted on the longitudinal guide rail, with one side of the slider fixedly connected to the chain 8.

[0033] When the drive motor drives the sprocket to rotate forward and backward through the shaft, the chain moves along the sprocket and at the same time drives the longitudinal slider 3 to slide back and forth along the extension path of the longitudinal guide rail 2. The longitudinal slider is also fixedly provided with a fixed seat 4, and the fixed seat is provided with a bearing.

[0034] like Figure 1 and 2 As shown, the longitudinal transmission mechanisms are symmetrically arranged on both sides of the riverbank, and the transverse transmission mechanism 10 is vertically arranged between the two longitudinal transmission mechanisms, located above the water surface. The transverse transmission mechanism includes a support base 12, a transverse guide rail 13, a lead screw 14, a nut seat 15, and a transverse slider 16. The left and right ends of the support base 12 are fixedly connected to the longitudinal slider 3 of the longitudinal transmission mechanism, and the upper surface of the support base 12 is provided with transverse guide rails 13 at intervals.

[0035] Each transverse guide rail is fitted with a transverse slider 16. In this embodiment, each transverse guide rail is provided with two transverse sliders at intervals, for a total of four. Each transverse slider is fixedly mounted with a nut seat 15 at its top. A transmission screw 14 is fitted inside the nut seat 15. The left and right ends of the screw are rotatably mounted with the fixed seat 4 on the longitudinal slider, and one end is connected to a motor. An ice-breaking mechanism 11 is also fixedly mounted on the top surface of the nut seat.

[0036] With this setup, when the drive motor controls the lead screw to rotate in both directions, it can simultaneously drive the nut seat on the lead screw to slide left and right on the horizontal guide rail using the horizontal slider. This allows the ice-breaking mechanism to move left and right on the water surface. Furthermore, through the cooperation of the longitudinal and horizontal transmission mechanisms, the longitudinal slider can be used to move the ice-breaking mechanism back and forth along the direction of water flow. The lead screw transmission can then control the left and right sliding of the ice-breaking mechanism on the horizontal plane, thereby enabling adjustment of the ice-breaking mechanism at different positions and facilitating the comprehensive breaking of the ice surface.

[0037] like Figure 3 and Figure 4As shown, the ice-breaking mechanism includes a motor 18, an eccentric wheel bearing seat 19, an eccentric wheel 20, a vertical rod 21, and an ice-breaking blade 23. The motor 18 is fixedly mounted on the top surface of the nut seat via a motor seat 17. The motor output shaft is driven by the eccentric wheel bearing seat 19 and connected to the eccentric wheel 20. The vertical rod 21 is rotatably connected to the eccentric wheel, and the bottom of the vertical rod extends downward and is hinged to the connecting seat 22 on the ice-breaking blade 23.

[0038] When the drive motor 18 is working, it can simultaneously drive the eccentric wheel 20 to rotate. During the rotation of the eccentric wheel, the vertical rod 21 can drive the ice-breaking blade 23 to move up and down reciprocally, so that the ice surface can be broken through the ice-breaking blade.

[0039] Furthermore, such as Figure 4 As shown, in this embodiment, the ice-breaking blade 23 includes triangular pyramid-shaped blades evenly distributed at the bottom, i.e., it has a structure that is wider at the top and narrower at the bottom. The bottom of the blade is a thin blade, and the two ends of the bottom blade are arc-shaped. The blades are arranged in a grid pattern. When cutting the ice surface from top to bottom, ideally the ice surface can be cut into small square-shaped pieces of broken ice.

[0040] Alternatively, based on the aforementioned icebreaker blade, the eccentric wheel is not connected to the motor 18 at its far end. Instead, the eccentric wheel is directly connected to the shaft, and the shaft is installed in the bearing housing. A counterweight is provided on the icebreaker blade. In this way, when the control nut seat of the shore drive mechanism slides laterally on the ice surface, since the ice thickness of the water conveyance channel is generally about 5 cm, the icebreaker blade can be driven to move up and down through the cooperation of the eccentric wheel and the icebreaker blade. That is, when the icebreaker blade encounters the ice layer during its lateral sliding, it will use its powerful force and weight to apply pressure, thereby breaking and pushing the ice layer to achieve the icebreaking work.

[0041] After the ice surface is broken up, the downstream winding and melting mechanism intercepts and melts the ice fragments, such as... Figure 5 As shown, the winding and melting mechanism is located on the riverbank downstream of the ice-breaking mechanism. The winding and melting mechanism includes a water supply mechanism, a net assembly, and a winding mechanism 25. The water supply mechanism includes a water collection well 27, a high-pressure pump 29, a water supply pipe 30, and a water spray pipe 32. The input end of the high-pressure pump 29 is connected to the water collection well 27 through a pipe. The output water volume is adjusted by the valve 28 on the pipe. The water collection well contains constant-temperature hot water. The output end is connected to the water spray pipe 32 through the water supply pipe 30. The water spray pipe is fixedly installed on the top of the rope net body of the net assembly in the transverse direction by a pipe clamp, and the end extends to the opposite side of the riverbank and is closed and fixed.

[0042] The water spray pipe is evenly provided with spray holes 35, with one pipe clamp every 1000mm. The water delivery hole is set every 200mm after the first pipe clamp. The number of water delivery holes is controlled at 3 to 6 per m, and the size of the water delivery hole is not greater than 2 / 3 of the pipe diameter and not less than 1 / 5 of the pipe diameter. The specific size can be adjusted according to the floating ice in the river and the actual conditions of the channel.

[0043] like Figure 5-7 As shown, the barrier net assembly is set perpendicular to the river surface and includes a rope net body and a flipping guide rod assembly. In this embodiment, the rope net body is a nylon rope net 31. Flipping guide rod assemblies are symmetrically arranged on the left and right sides of the nylon rope net 31. The flipping guide rod assembly includes a fixed guide rod a33, a fixed guide rod b36, and a support rod 34. The top of the fixed guide rod a is fixedly connected to the water spray pipe 32, and the bottom is hinged to the fixed guide rod b36. The bottoms of the fixed guide rods b36 on both sides are fixedly connected to the support rods 34. The support rods 34 are fixed to the bottom of the nylon rope net by steel wire ropes or pipe clamps, etc. The two fixed guide rods b are respectively connected to the winding mechanism by traction ropes 26. Furthermore, the hinge point connecting the fixed guide rod a33 and the fixed guide rod b36 is exactly flush with the horizontal plane.

[0044] like Figure 6 As shown, the winding mechanism includes a winch motor 38 and a winch 39. One end of the traction rope is fixedly connected to the bottom of the fixed guide rod b, and the other end is wound around the winch 39. The winch is driven by the winch motor 38 installed in the mounting base 37. When the winch motor 38 drives the winch to rotate forward, the traction rope is wound around the winch, and at the same time, the fixed guide rod b rotates backward about the hinge point as the axis of rotation towards the upstream ice-breaking mechanism. This causes the rope net body connected to it to flip upward from a vertical state to lift the ice blocks above the water surface. Then, hot water is sprayed onto the ice fragments held by the water spray pipe to melt the ice.

[0045] Furthermore, tension springs (not shown in the figure) are connected between fixed guide rod a33 and fixed guide rod b36. In their natural state, both guide rods are vertical. When the fixed guide rod b is folded upwards by the winding mechanism, the tension springs are compressed and remain compressed until the ice in the nylon rope net melts. Then, the winch releases the traction rope, and the two guide rods reset under the action of the tension springs. Rewinding the traction rope again flips the fixed guide rod b back up. Repeating these steps completes the ice-breaking process in the channel or river.

[0046] Furthermore, such as Figure 7As shown, the bottom of the fixed guide rod b is fixedly connected to a connected chamber or airbag 42 via a connecting rod 41. The airbags are connected to each other via an air pipe 43. An air inlet 44 is also provided on the edge airbag. In the initial state, water is injected into each airbag to increase its volume. The weight of each connected airbag or chamber overcomes buoyancy and falls into the water to intercept the ice. When water is drained and air is introduced into each chamber or airbag, the volume of each connected airbag or chamber decreases. Under the action of buoyancy, it floats upward, thereby driving the main body of the rope net connected to it to flip up from the vertical state to lift the ice to the water surface. Then, hot water is sprayed onto the ice fragments held by the water spray pipe to melt the ice.

[0047] This invention provides an ice-breaking and melting device for water conveyance channels. In use, along the water flow direction, the longitudinal and lateral transmission mechanisms set at the upstream of the channel control the longitudinal and lateral transmission of the ice-breaking blades. Then, the rotation of the eccentric wheel driven by the motor drives the ice-breaking blades to reciprocate up and down cutting motion. After the ice-breaking work is completed, the ice fragments flow downstream under the action of the water flow. At this time, the nylon rope net is flipped upward by controlling the flipping guide rod group of the nylon rope net, thereby flipping the main body of the rope net located underwater upward, so as to scoop up the floating ice on the ice surface and bring it above the water surface. Then, hot water is sprayed onto the ice fragments held by the rope net body through the water spray pipe to melt the ice.

[0048] This invention can achieve the combined effects of ice breaking, ice blocking, and ice melting. After breaking the ice on the water surface, the ice block is lifted off the water surface and then heat exchange occurs, which accelerates the melting of the ice block, reduces the impact on the water surface, improves the heat exchange efficiency, and prevents refreezing, thereby facilitating the smooth flow and safety of the channel.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
