Description

Technical Field

[0001] The invention relates to the field of anti-icing of river sluices, and in particular to an air bubble type anti-icing structure for river sluices. Background Art

[0002] In cold regions, temperatures plummet in winter, making the waters surrounding dams extremely susceptible to freezing. The formation and expansion of ice creates immense pressure on the dam structure, severely threatening its safe and stable operation and affecting its normal water diversion, flood control, and other functions. To address this issue, microbubble generating equipment is currently commonly used for anti-icing. This equipment uses fixed points on the dam's piers or bridge railings. A central bracket equipped with a vortex-shaped aeration tube is suspended in the water using ropes, chains, or metal rods. The suspension depth can be adjusted based on actual needs. During operation, an air pump delivers gas into the aeration tube, releasing microbubbles in the target water layer. This prevents freezing by disturbing the water and improving heat exchange efficiency.

[0003] However, during the anti-freezing process, the vortex-shaped aeration tube is directly exposed to the water. Impurities such as mud, aquatic plants, and floating garbage in the river can easily adhere to and entangle the surface of the aeration tube. In particular, once the air holes of the aeration tube are covered and blocked by impurities, the gas delivered by the air pump cannot be discharged smoothly to form microbubbles, and the anti-freezing efficiency will be greatly reduced. In addition, when the gate is anti-freezing, it is inconvenient to reasonably adjust the position of the aeration tube in the water according to changes in water temperature and ice conditions, which makes it difficult to generate sufficient and effective microbubbles in the key water layer, resulting in a significant reduction in the anti-icing efficiency and failure to achieve the expected anti-freezing effect. Summary of the Invention

[0035] The following is combined with Figure 1 - Figure 12 This application is described in further detail.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 A bubble-type anti-icing structure for a river sluice comprises two piers 1 and a gate assembly 2 fixedly arranged between the two piers 1; a support plate 3 that can move up and down is arranged between the two piers 1; a plurality of anti-icing assemblies 4 for preventing the gate assembly 2 from being frozen are arranged at the bottom of the support plate 3; the anti-icing assembly 4 comprises a connecting pipe 41 arranged at the bottom of the support plate 3; a vortex-shaped aeration pipe 42 is arranged at the bottom of the connecting pipe 41.

[0037] See Figure 1 、 Figure 2 and Figure 5 The lower end of the support plate 3 is provided with a protective component 5 corresponding to the number of the anti-icing components 4 and used to protect the anti-icing components 4. The protective component 5 includes a mounting member 51 arranged on the front side of the support plate 3. Two semicircular protective tubes 52 are rotatably provided on the mounting member 51. The two semicircular protective tubes 52 are fitted together at one end away from the mounting member 51 to provide surrounding protection for the aeration pipe 42, and a plurality of water filtering holes are opened on the two semicircular protective tubes 52.

[0038] See Figure 2 and Figure 7The front side of the support plate 3 is fixedly provided with a mounting plate 10, and the mounting member 51 includes a connecting plate 511 arranged at the bottom of the mounting plate 10 by bolts. Two connecting rods 512 symmetrically distributed on the left and right are fixedly provided at the bottom of the connecting plate 511, and the semicircular casing 52 is rotatably connected to the connecting rod 512. A U-shaped plate 513 is fixedly provided between the two connecting rods 512. The semicircular casing 52 is located on the outer wall of the connecting rod 512 at the two horizontal sections of the U-shaped plate 513, and the bottom end of the connecting rod 512 is connected to the horizontal section of the inner lower end of the U-shaped plate 513. The two horizontal sections inside the U-shaped plate 513 are in contact with the upper and bottom of the semicircular casing 52 respectively.

[0039] When the gate assembly 2 is to be protected from freezing, the connecting plate 511 is first installed on the bottom of the mounting plate 10 by means of bolts, so that the two semicircular casings 52 can be installed at the lower end position of the corresponding connecting pipe 41. At this time, the two semicircular casings 52 can be freely rotated by the connecting rod 512, so that the use form of the corresponding two semicircular casings 52 can be reasonably adjusted according to the two situations of protecting the gate assembly 2 from freezing and preventing blockage when the gate assembly 2 is draining.

[0040] See Figure 2 and Figure 7 A connector 6 is provided between the two semicircular protective tubes 52 to allow the two semicircular protective tubes 52 to fit together. The connector 6 can connect the multiple protective assemblies 5 in series horizontally after the multiple protective assemblies 5 are changed in their use configuration. A first socket 11 is provided at the top of the semicircular protective tubes 52. The connector 6 includes a connecting block 62 and two insert rods 61 at the bottom of the connecting block 62 that cooperate with the first socket 11.

[0041] After the two semicircular casings 52 are installed at the lower end positions of the corresponding connecting pipes 41, the two insertion rods 61 are then inserted into the corresponding two first sockets 11. At this time, the two insertion rods 61 can be used to connect and lock the two semicircular casings 52, so that the two semicircular casings 52 are combined into a circular casing and are stably located at the lower end position of the connecting pipe 41.

[0042] See Figure 5 and Figure 6A circular bracket 44 is provided at the bottom of the aeration tube 42, and a plurality of fixing members 45 for fixing the aeration tube 42 on the upper part thereof are provided on the circular bracket 44. The fixing member 45 includes a first clamping block 451 fixedly provided on the circular bracket 44. A plurality of grooves are provided on the upper part of the circular bracket 44, and a slider 452 is slidingly provided in the groove. A return spring 453 is fixedly provided between the slider 452 and the inner wall of the groove. A second clamping block 454 opposite to the first clamping block 451 is fixedly provided on the upper part of the slider 452, and the sides of the first clamping block 451 and the second clamping block 454 close to each other are both in contact with the outer side of the aeration tube 42, and the upper parts of the first clamping block 451 and the second clamping block 454 are both sloped.

[0043] After the installation of the semicircular casing 52 is completed, the staff can install the aeration pipe 42 in a spiral shape on the circular bracket 44. When installing the aeration pipe 42, the aeration pipe 42 is located between the multiple groups of first clamps 451 and second clamps 454. At this time, the reset spring 453 is used to cooperate so that the sides of the first clamp 451 and the second clamp 454 that are close to each other are both fitted with the outer side of the aeration pipe 42, so that the aeration pipe 42 can be stably installed in a spiral shape on the circular bracket 44.

[0044] See Figure 3 and Figure 4 The bottom end of the connecting pipe 41 and the upper end of the aeration pipe 42 are both fixedly provided with a connecting head 43, and the two connecting heads 43 are connected by threads.

[0045] See Figure 5 and Figure 11 A T-shaped block 14 is fixedly provided on the outside of the circular bracket 44, and a T-shaped slot 15 for use with the T-shaped block 14 is opened on the inner wall of the U-shaped plate 513 close to the circular bracket 44, and the side of the T-shaped block 14 away from the circular bracket 44 is located in the T-shaped slot 15.

[0046] After installing the aeration pipe 42 on the circular bracket 44, the staff first uses the connecting head 43 to connect the aeration pipe 42 with the connecting pipe 41, and then the circular bracket 44 can be placed into the corresponding two semicircular protective tubes 52, and then the T-shaped block 14 on the outside of the circular bracket 44 is aligned with the T-shaped slot 15 on the U-shaped plate 513. As the circular bracket 44 slowly moves down to the inside of the two semicircular protective tubes 52, the T-shaped block 14 gradually embeds into the bottom end of the T-shaped slot 15. Therefore, when the circular bracket 44 is located inside the two semicircular protective tubes 52, the cooperation of the T-shaped slot 15 and the T-shaped block 14 can stably support the circular bracket 44. Even under the impact of water flow or fluctuations, the circular bracket 44 can remain stable, avoiding the aeration pipe 42 from swinging due to swinging, affecting the later anti-freezing effect.

[0047] See Figure 2 、 Figure 3 and Figure 4 An air guide cavity 7 is opened inside the support plate 3, and the top end of the connecting pipe 41 passes through the air guide cavity 7. An air pump 8 is fixedly provided on the upper right side of the support plate 3. The air delivery end of the air pump 8 is connected to an air delivery pipe 9, and the end of the air delivery pipe 9 away from the air pump 8 passes through the air guide cavity 7.

[0048] See Figure 1 and Figure 8 , the upper part of the two gate piers 1 is provided with an adjustment component 17 for adjusting the use height of the support plate 3. The adjustment component 17 includes a shell 171 fixedly arranged on the upper part of the gate pier 1, and a rotating shaft 172 is rotatably arranged inside the shell 171. A motor 173 is fixedly arranged on the front of the shell 171, and the output shaft of the motor 173 is connected to one end of the rotating shaft 172. A gear 174 is fixedly arranged on the rotating shaft 172. Gear plates 175 are fixedly arranged on the left and right sides of the upper part of the support plate 3. The gear plate 175 is engaged with the gear 174 and its top end passes through the shell 171.

[0049] After the circular bracket 44 is installed to the inner side of the corresponding two semicircular casings 52, the motor 173 drives the rotating shaft 172 to rotate, and the rotation of the rotating shaft 172 drives the gear 174 to rotate. The rotation of the gear 174 drives the tooth plate 175 to move downward. The movement of the tooth plate 175 can drive the tooth plate 175 to move downward. The downward movement of the tooth plate 175 can drive the support plate 3 to move downward, thereby driving the two semicircular casings 52 and the aeration pipe 42 inside it to move downward. Then, when the aeration pipe 42 sinks to the preset position in the water, the bottom ends of the two semicircular casings 52 also sink into the water, and the upper parts of the semicircular casings 52 are higher than the water surface.

[0050] Then, motor 173 stops, and air pump 8 begins operating. Air pump 8 uses air pipe 9 to input air into air guide chamber 7. The air then enters connecting pipe 41 through air guide chamber 7 and is finally discharged from vortex-shaped aeration pipe 42. The large number of microbubbles discharged from aeration pipe 42 continuously disturb the water as they rise, promoting heat exchange between the upper and lower layers of the water, raising the water temperature. This also breaks the static environment required for ice formation on the water surface, effectively preventing ice from forming in the water near gate assembly 2 and providing anti-freeze protection for gate assembly 2. Furthermore, during use, aeration pipe 42 is surrounded by two semicircular casings 52. The evenly distributed water filter holes on the casings allow water and microbubbles to pass through, while blocking the entry of large impurities such as aquatic plants and garbage, preventing clogging of the air outlet holes in aeration pipe 42. This ensures the effectiveness of aeration pipe 42 and does not affect the normal anti-freeze operation. Furthermore, the protective effect of the semicircular casings 52 significantly reduces the frequency of cleaning aeration pipe 42, extending the life of aeration pipe 42.

[0051] At the same time, when the temperature in the water is low or thin ice has been formed, the motor 173 can be used to drive the support plate 3 to move upward, thereby driving the aeration pipe 42 to move upward quickly, so that microbubbles are densely generated between the bottom of the thin ice and the water surface. The rising force and disturbing effect of the bubbles are used to break up the thin ice that has been formed, and prevent the ice layer from further expanding and thickening, further improving the anti-freezing effect of the gate assembly 2.

[0052] After the anti-icing operation is completed, the motor 173 can be started in reverse, so that the gear 174 drives the tooth plate 175 to move upward, and the anti-icing assembly 4 is lifted out of the water. When the aeration tube 42 needs to be cleaned, the staff can pull the second clamping block 454 to move, and then pull the aeration tube 42 to move it out from between the first clamping block 451 and the second clamping block 454. Compared with the method of fixing the aeration tube 42 with a cable tie, this disassembly method is simpler and more convenient, and it is also faster to install the cleaned aeration tube 42.

[0053] See Figure 2 、 Figure 9 and Figure 10 An L-shaped plate 12 is fixedly provided on both the left and right sides of the bottom of the support plate 3 , and a second socket 13 for use with the insertion rod 61 is opened on the inner horizontal section of the L-shaped plate 12 .

[0054] See Figure 1 and Figure 7 A positioning block 16 is fixedly provided at the lower end of each of the two semicircular casings 52 which are away from each other, and a circular opening is opened on the positioning block 16.

[0055] After the anti-icing work of the gate assembly 2 is completed, when the gate assembly 2 needs to be raised for drainage, the motor 173 can be started in reverse at this time, so that the gear 174 drives the tooth plate 175 to move upward, and the anti-icing assembly 4 and the protective assembly 5 are lifted from the water. Then the staff can pull the connecting block 62 to move the two plug rods 61 out of the corresponding two semicircular protective tubes 52, thereby canceling the connection lock of the two semicircular protective tubes 52, and then rotate the multiple semicircular protective tubes 52 to make them horizontal. The semicircular protective tubes 52 on the leftmost and rightmost sides are respectively fitted with the two L-shaped plates 12, and then the two plug rods 61 on the connecting block 62 are respectively inserted into the first sockets 11 on the corresponding semicircular protective tubes 52 on the two adjacent anti-icing assemblies 4. At the same time, the connecting plug rod 61 on the outermost connecting block 62 can be respectively inserted into the first socket 11 on the semicircular protective tube 52 and the second socket 13 on the L-shaped plate 12, so that multiple sets of connecting parts 6 can be used to horizontally connect multiple semicircular protective tubes 52 in series at the bottom of the support plate 3 (such as Figure 9 As shown), the staff then inserts the external horizontal plate into the circular openings on the plurality of positioning blocks 16 (as shown Figure 12As shown), the overall rigidity of the multiple semicircular casings 52 arranged horizontally is further enhanced to prevent them from shaking under the impact of water flow.

[0056] Then the motor 173 works to drive multiple semicircular protective tubes 52 connected in series horizontally to move downward until the bottom end of the semicircular protective tubes 52 is immersed in water and the water level is lower than the bottom of the positioning block 16. At this time, multiple semicircular protective tubes 52 connected in series form an interception barrier in front of the gate assembly 2. The water filtering holes and the enclosure structure on the surface of the semicircular protective tubes 52 can effectively block floating objects such as aquatic plants and garbage, preventing them from impacting the gate assembly 2 with the water flow or clogging the gate, thereby providing a clean water flow environment for the drainage operation of the gate assembly 2.

[0057] Moreover, after the drainage is completed, there is no need to change the usage form of the multiple semicircular protective tubes 52. The motor 173 drives the multiple semicircular protective tubes 52 in series to continue to move downward, so that the aeration pipe 42 moves down to a preset position in the water. The multiple semicircular protective tubes 52 in series can also be used to continue to protect the aeration pipe 42, blocking large-volume impurities such as aquatic plants and garbage from entering, avoiding blockage of the air outlet of the aeration pipe 42, and further improving the applicability of the semicircular protective tubes 52.

[0058] During the specific operation, the corresponding two semicircular protective tubes 52 are first installed on the mounting plate 10 using the mounting member 51, and then the two semicircular protective tubes 52 are combined into a circular protective tube using the connecting member 6. Then, the aeration pipe 42 can be installed on the circular bracket 44 using the fixing member 45, and then the circular bracket 44 can be stably installed in the circular protective tube composed of the two semicircular protective tubes 52. Then, the adjustment component 17 can be used to drive the aeration pipe 42 and the two semicircular protective tubes 52 to move down to the predetermined position.

[0059] Then the motor 173 stops working and the air pump 8 starts working. The air pump 8 can discharge a large number of microbubbles from the aeration pipe 42, which continuously disturb the water body during the rising process in the water, thereby realizing anti-freezing protection for the gate assembly 2. At this time, the semicircular casing 52 can block the entry of large impurities such as aquatic plants and garbage, and prevent the air outlet of the aeration pipe 42 from being blocked, which will not affect the normal anti-freezing work. It can also greatly reduce the frequency of cleaning the aeration pipe 42 and extend the service life of the aeration pipe 42. When the aeration pipe 42 needs to be cleaned, the fixing member 45 is used to facilitate the disassembly of the aeration pipe 42. Compared with the method of fixing the aeration pipe 42 with a cable tie, this disassembly method is simpler and more convenient, and the installation of the cleaned aeration pipe 42 is also faster.

[0060] After the anti-freezing work of the gate assembly 2 is completed, when the gate assembly 2 needs to be raised for drainage, multiple sets of connecting parts 6 and L-shaped plates 12 can be used to horizontally connect multiple semicircular protective tubes 52 in series at the bottom of the support plate 3. Multiple semicircular protective tubes 52 connected in series form an interception barrier in front of the gate assembly 2. The water filtering holes and enclosure structure on the surface of the semicircular protective tubes 52 can effectively block floating objects such as aquatic plants and garbage, preventing them from impacting the gate assembly 2 with the water flow or clogging the gate, thereby providing a clean water flow environment for the drainage operation of the gate assembly 2.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
