Description

Technical Field

[0001] The present invention relates to the technical field related to water conservancy and hydropower engineering buildings, and specifically to an anti-icing device for the water surface of a dam body. Background Art

[0002] It is well known that after the coming of winter, water conservancy and hydropower projects and hydraulic structures in cold areas are prone to ice formation. If the ice on the water surface is not handled in time, the ice climbing force generated when the water surface freezes will cause structural damage to the gates and hydraulic structures, increasing the cost of subsequent maintenance. The existing methods are mostly to clean the ice surface manually using tools, but manual cleaning is dangerous and costly. Another method is to prevent the water surface from freezing through a bubble anti-icing device. The principle of the bubble anti-icing device is to release a large number of microbubbles into the water body through a pipe body, and the movement of microbubbles in the water disturbs the water body, forming heat exchange and the energy of microbubble rupture to prevent ice crystals from gathering in the water, effectively preventing the formation of ice layers. The bubble anti-icing device has the advantages of strong reliability, good anti-icing effect, and environmental protection and no pollution.

[0003] For example, the invention with the publication number CN114108542B and the publication date of March 1, 2022, entitled "An anti-icing device and method for water conservancy facilities", discloses an anti-icing device and method for water conservancy facilities, which belongs to the technical field of water conservancy and hydropower facility protection. The anti-icing device is a microbubble anti-icing device arranged underwater to prevent the damage of ice cover static pressure and drifting ice to hydraulic facilities and buildings, especially dams (gates), reservoirs, rivers, hydropower stations and other water conservancy hub projects. The anti-icing device includes a gas diffuser, which is provided with a mushroom-shaped aeration head and a base connector; a manually controlled conveying system, which is composed of a pipeline, a ball valve and a bus; an automatic control system, which is composed of a temperature sensor, a pressure sensor, a jet cycle flow sensor, a water level sensor, a proportional valve, and a video monitor; a remote monitoring system; and an air supply system, which is composed of a blower, a screw compressor, a gas storage tank, a filter and a cold dryer. The invention changes the anti-icing device and method, has good real-time performance, low failure rate, strong practicality, and good anti-icing damage effect; its production process and installation are simple.

[0004] The shortcoming of the prior art is that the bubble anti-icing device is mostly fixed on the side wall of the dam body, so that the air outlet pipe of the bubble anti-icing device is also fixedly installed, making the bubble anti-icing device easily affected by the dirty environment at the bottom of the water, increasing the probability of blockage. At the same time, the anti-icing range of the bubble anti-icing device is small and the anti-icing range of the bubble anti-icing device is fixed. Summary of the invention

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig. 9 The present invention is further described in detail.

[0031] An embodiment provided by the present invention relates to an anti-icing device for the water surface of a dam body, comprising an air pump, an air inlet pipe body 1 and an air outlet pipe 2, wherein the output end of the air pump is connected to the air inlet pipe body 1, and a plurality of air outlet pipes 2 are evenly connected to the air inlet pipe body 1, and each of the air outlet pipes 2 is evenly provided with an air outlet hole 3, and further comprises a floating unit, wherein the floating unit comprises a floating body 4 and a connecting rope 5, and a plurality of connecting ropes 5 are evenly provided at the top end of the air inlet pipe body 1 along its axial direction, and a floating body 4 is connected to the top end of each of the connecting ropes 5, and the floating body 4 floats on the water surface and provides tension to the air inlet pipe body 1 through the connecting rope 5, so that the air outlet pipe 2 is suspended in the water by the floating body 4 floating on the water surface.

[0032] Specifically, the air pump is used to transport gas to the air inlet pipe body 1 and the air outlet pipe 2. The air pump and the air inlet pipe body 1 are connected by a telescopic hose 6. The telescopic hose 6 can be extended and bent, so that the connection between the air inlet pipe body 1 and the air pump is more flexible. It is preferably a corrugated tube. The floating body 4 can float on the water surface. The floating body 4 can provide buoyancy for the connecting rope 5 and the air inlet pipe body 1, so that the air inlet pipe body 1 floats inside the water body and will not sink to the bottom of the water. Preferably, each floating body 4 is provided with a display element 7 with a bright color such as yellow, red, etc. at the top. The display element 7 makes it easy for the staff to observe the position of the floating body from a distance, and then to know the approximate direction of the air inlet pipe body 1. When the floating body 4 floats on the water surface The display element 7 is more conspicuous on the water surface, which is convenient for the staff to observe the positions of the floating body 4 and the air inlet pipe body 1. A plurality of air outlet pipes 2 are evenly arranged on the air inlet pipe body 1, and each air outlet pipe 2 is arranged perpendicular to the air inlet pipe body 1. When it is necessary to perform anti-icing operations on the water surface of the dam body 8, the staff installs the air pump in the dam body 8 or other buildings, and then places the air inlet pipe body 1 in the water body, and sets the axial direction of the air inlet pipe body 1 parallel to the dam body 8. When the air inlet pipe body 1 is placed in the water body, due to the self-gravity of the air inlet pipe body 1 and the gravity of the air outlet pipe 2, the air inlet pipe body 1 and the air outlet pipe 2 enter the water body, and the air inlet pipe body 1 pulls the connecting rope 5 until the connecting rope 5 is completely straightened, so that The connecting rope 5 causes the buoyancy generated by the floating body 4 on the water surface to act on the air inlet pipe body 1. The length of the connecting rope 5 can be adjusted. Preferably, the lengths of the connecting ropes 5 are set to the same length. Since the air inlet pipe body 1 and the air outlet pipe 2 are arranged perpendicular to each other, the air inlet pipe body 1 is parallel to the water surface, and the air outlet pipe 2 is vertically arranged in the water body. Preferably, a plurality of anti-slip ropes are evenly arranged on the side wall of the air inlet pipe body 1, and the anti-slip ropes can be connected to the side wall of the dam body 8. The air inlet pipe body 1 is positioned to a certain extent by the anti-slip ropes. The air pump is transported to the air outlet pipe 2 through the air inlet pipe body 1, so that a large number of microbubbles are released in the air outlet pipe 2. The water body is disturbed by the movement of the microbubbles, and the gas content in the water body is increased, so that the surface water The body temperature increases, which effectively reduces the presence of ice nuclei in the water body, thereby avoiding the formation of ice in the water body, and the bubbles move in the water body toward the water surface, so that the water surface will not form an ice surface at low temperatures, with a high anti-icing effect, and when the air inlet pipe body 1 and the air outlet pipe 2 are sprayed in the water body, the gas will produce a certain reaction force on the air inlet pipe body 1 and the air outlet pipe 2, so that the air inlet pipe body 1 and the air outlet pipe 2 will shake in the water body, so that the movement range of the microbubbles released in the air outlet pipe 2 is increased, so that the microbubbles can increase the anti-icing area of ​​the water surface, and the air outlet pipe 2 is not fixed, and the air outlet pipe 2 moves with the shaking of the floating body 4 and the water body, so that the probability of blockage of the moving air outlet pipe 2 is greatly reduced.

[0033] The shortcoming of the prior art is that the bubble anti-icing device is mostly fixed on the side wall of the dam body 8, so that the air outlet pipe 2 of the bubble anti-icing device is also fixedly installed, making the bubble anti-icing device easily affected by the dirty environment at the bottom of the water, increasing the probability of blockage. At the same time, the anti-icing range of the bubble anti-icing device is small and the anti-icing range of the bubble anti-icing device is fixed.

[0034] The beneficial effects of the present invention are as follows: an air pump is used to transport gas into the air inlet pipe body 1 and the air outlet pipe 2, so that bubbles are generated in the water body by the air outlet pipe 2, and the floating body 4 moves on the water surface by floating, so that the floating body 4 drives the air inlet pipe body 1 and the air outlet pipe 2 to move through the connecting rope 5, so that the air outlet pipe 2 has a certain moving range, thereby increasing the range of releasing microbubbles in the air outlet pipe 2, increasing the anti-icing area of ​​the water surface, preventing partial freezing of the water surface of the dam body 8, improving the anti-icing effect on the water surface of the dam body 8, and through the shaking of the air outlet pipe 2 in the water body, the probability of blockage of the air outlet pipe 2 can be greatly reduced.

[0035] Furthermore, a plurality of counterweight ropes 9 are evenly connected to the outer wall of the air inlet pipe body 1 along its axial direction, and each of the counterweight ropes 9 is located at a portion between two adjacent air outlet pipes 2 on the air inlet pipe body 1, and each of the counterweight ropes 9 is connected to a counterweight box 10; optionally, a box cover 11 is threadedly connected to the bottom end of each of the counterweight boxes 10, and a plurality of counterweight blocks 12 are arranged in each of the counterweight boxes 10, and the number of counterweight blocks 12 in each of the counterweight boxes 10 is optional. Specifically, before the staff places the air inlet pipe body 1 into the water body, the staff uses a tool to open the box cover 11 at the bottom end of the counterweight box 10, and then adjusts the counterweight box 10 according to the buoyancy generated by the floating body 4 on the water surface. 0, and then adjust the length of the counterweight rope 9 according to the depth of the water body. When the air intake pipe body 1 is placed in the water body, the counterweight box 10 and the counterweight 12 sink to the bottom of the water, so that the counterweight box 10 and the counterweight 12 apply a certain counterweight tension to the air intake pipe body 1 through the counterweight rope 9, so that the movement range of the air intake pipe body 1 is controlled, so that the movement range of the air intake pipe body 1 and the air outlet pipe 2 is within the range close to the side wall of the dam body 8, and the range of the microbubbles released in the air outlet pipe 2 is close to the side wall of the dam body 8, ensuring that the microbubbles released in the air outlet pipe 2 can be released at the position of the dam body 8, preventing partial ice on the water surface of the dam body 8, and improving the anti-icing effect on the water surface of the dam body 8.

[0036] In another embodiment provided by the present invention, a plurality of arc-surface through holes 13 are uniformly provided on the outer wall of the air intake pipe body 1 along its axial direction, and an arc panel 14 is slidably and sealably installed in each of the arc-surface through holes 13, and a connecting pipe 15 is installed on each of the arc-surface through holes 14, and each of the connecting pipes 15 is interconnected with the air intake pipe body 1; grooves 16 are provided on the side walls at both ends of the arc-surface through holes 13 in the axial direction of the air intake pipe body 1, that is, a groove 16 is provided on one side wall of the same arc-surface through hole 13, and two corresponding grooves are provided on the side walls on both sides of the same through groove 16, each sliding seal in each of the grooves 16 is installed with an arc-shaped plate 17 (dynamic sealing between the arc plate 14 and the intake pipe body 1 is realized by the arc-shaped plate 17), and each arc plate 14 in each arc surface through hole 13 is connected to an arc-shaped plate 17 on both sides, that is, the two arc-shaped plates 17 are connected through an arc plate 14; each arc-shaped plate 17 in each of the arc surface through holes 13 and the inner wall of the corresponding groove 16 are connected by a first elastic member 18, that is, each arc-shaped plate 17 in a arc surface through hole 13 and the inner wall of the corresponding groove 16 are connected by the first elastic member 18.

[0037] Specifically, the connecting pipe 15 and the arc panel 14 are arranged perpendicular to each other. Since the air outlet pipe 2 is arranged basically vertically and the sliding seal is arranged in the connecting pipe 15, when the air inlet pipe body 1 is placed in the water body, the air outlet pipe 2 slides in the connecting pipe 15 under the action of gravity to form its end, that is, the air outlet pipe 2 slides in the connecting pipe 15 to the position where the end is limitedly connected. When the gas is transported in the air inlet pipe body 1, the air inlet pipe body 1 transports the gas to the connecting pipe 15 and the air outlet pipe 2. Since the gas acts on the side wall of the connecting pipe 15, Since the air intake pipe body 1 and the connecting pipe 15 are vertically connected, the gas in the air intake pipe body 1 needs to be bent at a certain angle when entering the connecting pipe 15, so that part of the gas acts on the side wall of the connecting pipe 15 away from the telescopic hose 6. Preferably, a passive plate 38 is provided at the top of the connecting pipe 15. When the gas enters the connecting pipe 15 from the air intake pipe body 1, the gas blows the passive plate 38 to move to the side away from the telescopic hose 6, so that the passive plate 38 drives the connecting pipe 15 to move to the side away from the telescopic hose 6. One side moves, and the passive plate realizes the two functions of guiding and force driving, so that the connecting pipe 15 drives the arc plate 14 to slide in the arc surface through hole 13. When the arc plate 14 slides in the arc surface through hole 13, the arc plate 14 drives the arc plate 17 to slide in the arc surface through hole 13, and the arc plate 17 stretches the first elastic member 18 (the first elastic member 18 is a component capable of telescopic reset, preferably a spring). When the force of the gas on the connecting pipe 15 is offset by the elastic force of the first elastic member 18, the first elastic member 18 will be arc-shaped. The plate 17 and the arc plate 17 are pulled back, so that when the gas is transported in the connecting pipe 15 and the air inlet pipe body 1, the arc plate 14 can slide back and forth in a straight line in the arc surface through hole 13, and the arc plate 14 can drive the connecting pipe 15 and the air outlet pipe 2 to perform a straight line reciprocating motion, so that the air outlet pipe 2 can increase the release range of microbubbles when performing a straight line reciprocating motion, increase the anti-icing range of the water surface, and effectively protect the dam body 8 from ice. In addition, the probability of blockage of the air outlet pipe 2 can be greatly reduced by shaking the air outlet pipe 2 in the water body.

[0038] Preferably, each connecting tube 15 is provided with an air outlet pipe 2 in a sliding seal, and each connecting tube 15 is provided with a reset ring 19 rotatably in the middle of the top end, and each reset ring 19 is connected to the top end of the corresponding air outlet pipe 2 via a second elastic member 20.

[0039] Specifically, when the gas is transported to the outlet pipe 2 in the connecting pipe 15, the outlet pipe 2 is subjected to the blowing force of the gas and its own gravity, so that the outlet pipe 2 slides in the connecting pipe 15 to form the end thereof. During the sliding process of the outlet pipe 2 in the connecting pipe 15, the outlet pipe 2 stretches the second elastic member 20 (the second elastic member 20 is a member capable of retracting and resetting, preferably a plurality of rubber ropes or rubber tubes), so that the second elastic member 20 is in a stretched state. When the gas transport volume is small, the gas acts on The force in the air outlet pipe 2 is reduced, and under the rebound effect of the second elastic member 20, the second elastic member 20 drives the air outlet pipe 2 to slide toward the water surface, so that the microbubbles released in the air outlet pipe 2 are closer to the water surface, and when the gas delivery rate changes, the second elastic member 20 can drive the air outlet pipe 2 to perform a linear reciprocating motion, so that the movement range of the microbubbles released in the air outlet pipe 2 in the water body is increased, thereby improving the bubble anti-icing effect, and the swaying of the air outlet pipe 2 in the water body can greatly reduce the probability of blockage of the air outlet pipe 2.

[0040] In another embodiment provided by the present invention, an auxiliary rotating unit is provided on the outer wall of each of the connecting pipes 15, and each of the auxiliary rotating units is used to drive the corresponding air outlet pipe 2 to rotate, and the auxiliary rotating unit includes a baffle 21 and an auxiliary ring plate 22, and an auxiliary ring plate 22 is installed on the outer wall of the bottom end of each of the connecting pipes 15, and each of the connecting pipes 15 and the auxiliary ring plate 22 are uniformly provided with a plurality of air outlet channels 23 along their circumferential direction, that is, each of the connecting pipes 15 and the auxiliary ring plate 22 are uniformly provided with a plurality of air outlet channels 23, one section of the air outlet channel 23 is a horizontal channel 24 perpendicular to the axial direction of the connecting pipe 15, and each of the horizontal channels 24 is interconnected with the corresponding connecting pipe 15, and the other section of the air outlet channel 23 is a vertical channel 25 parallel to the axial direction of the connecting pipe 15, and each end of the vertical channel 25 is connected to a nozzle 26, and the middle of each of the vertical channels 25 is provided with a slide groove 27, and each of the slide grooves 27 has a The sliding seal is provided with a baffle 21, each of which is provided with a connecting hole 28, each of which is provided in correspondence with its corresponding vertical channel 25, each of which is connected with the inner wall of the corresponding slide groove 27 by a third elastic member 29, the top of each of which is a funnel-shaped structure, the radius of which gradually decreases from the top to the bottom of each of which, and each of which is provided with a funnel-shaped structure at the top of each of which is provided with a connecting hole 28, each of which is provided with a connecting hole 28 corresponding to its corresponding vertical channel 25 ... The corresponding baffles 21 are wedge-shaped and matched with each other. Each of the baffles 21 is provided with a clamping plate 30 at one end inside the connecting pipe 15. A driven ring plate 31 is provided at the bottom end of the funnel-shaped structure on the outer wall of each of the outlet pipes 2. A plurality of driven plates 32 are evenly arranged on the top of each driven ring plate 31 along its circumferential direction, that is, each driven ring plate 31 is provided with a plurality of driven plates 32 along its circumferential direction, and each driven plate 32 and the corresponding nozzle 26 are used in conjunction with each other.

[0041] Specifically, when the gas does not enter the connecting pipe 15, the third elastic member 29 (the third elastic member 29 is a member capable of retracting and resetting, preferably a spring) provides a certain elastic force for the baffle 21, so that the baffle 21 closes the vertical channel 25. That is, at this time, the connecting hole 28 on the baffle 21 and the vertical channel 25 are misaligned with each other, so that the baffle 21 can close the vertical channel 25, so that the gas will not be discharged from the vertical channel 25 to the outlet pipe 2. When the gas is transported from the connecting pipe 15 to the outlet pipe 2, since the top of the outlet pipe 2 is a funnel-shaped structure, and the half of the funnel-shaped structure is The diameter gradually decreases from the top to the bottom, so that when the gas enters the outlet pipe 2 from the connecting pipe 15, the gas passes through the funnel-shaped structure at the top of the outlet pipe 2, so that the flow rate of the gas increases (due to the law of conservation of mass, the flow rate of the gas remains unchanged, however, at the bottom of the funnel-shaped structure, the area is small, resulting in an increase in the flow rate of the gas). The outlet pipe 2 is affected by the blowing force of the gas and its own gravity, and the outlet pipe 2 slides in the connecting pipe 15 to the end thereof, and the flow rate of the gas in the outlet pipe 2 increases. When the outlet pipe 2 moves in the connecting pipe 15 to the end thereof, due to the top of the outlet pipe 2 The funnel-shaped structure is a funnel-shaped structure, and the funnel-shaped structure at the top of the air outlet pipe 2 and the baffle plate 21 are wedge-shapedly matched with each other, so that the funnel-shaped structure at the top of the air outlet pipe 2 pushes the baffle plate 21 to slide toward one end inside the slide groove 27 until the funnel-shaped structure at the top of the air outlet pipe 2 slides to the position of the clamping plate 30. At this time, the connecting hole 28 on the baffle plate 21 is connected with the vertical channel 25, so that the gas can be discharged from the air outlet channel 23 and the nozzle 26, so that the gas in the nozzle 26 acts on the driven plate 32, so that the driven plate 32 drives the driven ring plate 31 to rotate, and the driven ring plate 31 drives the air outlet pipe 2 to rotate (due to the rotation of the reset ring 19). The second elastic member 20 is placed in the connecting pipe 15 so that the rotation of the driven plate 32 and the air outlet pipe 2 will not be affected by the reset ring 19. In this embodiment, the second elastic member 20 is a spring, so that the air outlet pipe 2 can drive the reset ring 19 to rotate in the connecting pipe 15 through the second elastic member 20, and the second elastic member 20 will not block the air outlet channel 23. The air outlet pipe 2 releases microbubbles while rotating, so that the microbubbles released in the air outlet pipe 2 have a certain initial rotational velocity, so that the microbubbles released in the air outlet pipe 2 can rotate to a certain extent, and the range of movement of the microbubbles is increased when the microbubbles rotate, thereby improving the bubble anti-icing effect.

[0042] As another embodiment provided by the present invention, preferably, an auxiliary groove 33 is provided on the outer wall of each of the driven plates 32, and a follower 34 is slidably installed in each of the auxiliary grooves 33, and each of the follower 34 and the inner wall of the corresponding auxiliary groove 33 are connected by a fourth elastic member 35, and each of the follower 34 is located inside the auxiliary groove 33 under the pulling action of the fourth elastic member 35.

[0043] Specifically, when the air outlet pipe 2 and the driven plate 32 rotate, the air outlet pipe 2 drives the driven member 34 in the auxiliary groove 33 to rotate, so that the driven member 34 is subjected to the centrifugal force when rotating, and the driven member 34 slides from the inside of the auxiliary groove 33 to the outside thereof, so that the driven member 34 slides to the outside of the auxiliary groove 33, and the driven member 34 provides a certain pulling force to the fourth elastic member 35 (the fourth elastic member 35 is a member capable of retracting and resetting, preferably a spring), so that the fourth elastic member 35 is in a stretched state, thereby increasing the force bearing surface of the driven plate 32 subjected to the jet force of the nozzle 26, so that the driven plate 32 and the driven member 34 are subjected to the jet force of the nozzle 26. The jet force in the nozzle 26 is increased, thereby increasing the rotation speed of the driven plate 32 and the air outlet pipe 2. When the rotation speed of the air outlet pipe 2 is increased, the initial rotation speed of the microbubbles released therefrom is increased, so that the movement range of the microbubbles is increased, and the anti-icing effect of the bubbles is improved. In addition, the rotation of the air outlet pipe 2 in the water body can greatly reduce the probability of blockage of the air outlet pipe 2. Even if the air outlet pipe 2 is blocked in the water body, the centrifugal force generated when the air outlet pipe 2 rotates can be used to throw the blockage at the blocked position of the air outlet pipe 2 out of the air outlet pipe 2 through the action of the centrifugal force, thereby further reducing the probability of blockage of the air outlet pipe 2.

[0044] As another embodiment provided by the present invention, preferably, a liquid stirring circular plate 36 is installed at the bottom end of each of the air outlet pipes 2, and a plurality of circular arc plates 37 are evenly arranged on each of the liquid stirring circular plates 36 along the circumferential direction thereof.

[0045] Specifically, when the air outlet pipe 2 rotates, the air outlet pipe 2 drives the liquid stirring circular plate 36 to rotate, and the liquid stirring circular plate 36 drives the arc plate 37 to rotate. When the arc plate 37 rotates inside the water body, the arc plate 37 can drive the water flow to form a vortex, so that the vortex drives the microbubbles released in the air outlet pipe 2 to move toward the water surface, which can effectively prevent the water surface from freezing. The vortex formed by the rotation of the arc plate 37 can prevent the bottom of the water from freezing, and can effectively prevent the bottom and the water surface from freezing.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
