Description

Technical Field

[0001] This invention relates to the field of reservoir ice prevention technology, and specifically proposes an ice prevention structure for reservoirs in high-altitude and cold regions. Background Technology

[0002] Ice prevention for reservoirs in high-altitude and cold regions is a crucial task to ensure the safe operation of reservoirs in winter, water resource allocation, and the stability of the surrounding ecological environment. Reservoir gates are key facilities for controlling water flow and regulating reservoir water levels. Winter icing may cause reservoir gates to become stuck, malfunction, or even damage to the gate structure due to excessive ice pressure, seriously threatening the safe operation of the reservoir. Therefore, it is necessary to prevent ice from forming on reservoir gates.

[0003] Currently, the most commonly used reservoir ice prevention technology in engineering is active ice prevention (preventing ice formation). The most common method of active ice prevention is the bubble ice prevention system. The bubble ice prevention system releases a large number of tiny bubbles into the water body through an underwater bubble generator. As the bubbles rise, they drive the water body to circulate up and down, transporting warm water from the bottom layer to the surface, breaking the inversion layer, and keeping the surface water temperature above the freezing point. At the same time, the bubble disturbance can prevent ice nuclei from forming and inhibit ice growth.

[0004] However, existing bubble anti-icing structures have the following problems during use: 1. Existing bubble anti-icing structures only disturb the surface layer and cannot circulate and disturb the deeper, warmer water layer. They are very sensitive to water level, and the water surface will still freeze when the water level is high and the temperature is low; 2. In extreme cold weather, when the temperature is significantly lower than normal, the water is more likely to freeze and the freezing speed is faster. The width of the bubble anti-icing structure in front of the reservoir gate may not meet the anti-icing requirements, and it is difficult to ensure that the water in a sufficient area remains ice-free; 3. If the existing bubble anti-icing structure is moved, it is easy for the bubble anti-icing structure to become unstable during use, affecting the anti-icing effect in front of the reservoir gate. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide an ice-proof structure for reservoirs in high-altitude and cold regions to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ice-proof structure for a reservoir in a cold region, comprising: four fixed frames, two connecting frames, a bubble generating mechanism, and a storage and protection mechanism. The four fixed frames are arranged in a matrix, with two fixed frames forming a group. The two groups of fixed frames are respectively fixedly installed on the side walls of the gate piers on both sides of the gate. A gate is provided at the gate (the gate and the control mechanism for controlling the gate are existing technologies; the control mechanism for controlling the gate is not shown in the figure). The connecting frames are slidably connected to the two fixed frames installed on the same gate pier, and the two connecting frames are symmetrically arranged along the length of the gate.

[0007] The bubble generating mechanism is installed between two connecting frames. The bubble generating mechanism includes three bubble generating parts arranged evenly from top to bottom between the two connecting frames. A reciprocating drive unit is provided between the two connecting frames. The bubble generating part located in the middle is fixedly connected to the connecting frame. The other two bubble generating parts move alternately along the length of the connecting frame under the drive of the reciprocating drive unit. A lifting and locking unit is also provided between the two connecting frames to drive it to move up and down and lock the connecting frame. The lifting and locking unit cooperates with the reciprocating drive unit and the three bubble generating parts to adjust the anti-icing width and anti-icing depth.

[0008] The storage and protection mechanism is installed between the tops of the gate piers on both sides of the gate and is located on top of the bubble generating mechanism. The storage and protection mechanism is used to store the bubble generating mechanism.

[0009] In one possible implementation, the storage and protection mechanism includes a fixed cover connected to the top of the gate piers on both sides of the gate opening. The fixed cover has a pick-and-place slot in the middle, and the pick-and-place slot has a drive source on both sides to move the connecting frame up and down.

[0010] In one possible implementation, the lifting and locking part includes a mounting base evenly arranged along its length on the top of the connecting frame, with the width of the middle mounting base being greater than the width of the other two mounting bases. A bidirectional hydraulic cylinder is mounted on the middle mounting base, and locking rods are slidably mounted on the other two mounting bases. Both ends of the bidirectional hydraulic cylinder are equipped with push assemblies that drive the corresponding locking rods to move. Two sets of arc-shaped supports are mounted on the side wall of the gate pier, each set of arc-shaped supports consisting of multiple arc-shaped supports evenly arranged from top to bottom. Two arc-shaped supports are also mounted along its length near the top of the side wall of the gate pier, with the arc-shaped protrusions of the arc-shaped supports facing away from the gate. The locking rods cooperate with the corresponding arc-shaped supports to lock the vertical movement of the connecting frame.

[0011] In one possible implementation, the jacking assembly includes a jacking block mounted on both telescopic ends of a bidirectional hydraulic cylinder. A receiving groove is provided on the mounting base on which the locking rod is mounted. The jacking block slides into the receiving groove. A guide post is mounted on the locking rod. A guide groove is provided on the jacking block to slide and cooperate with the guide post. When the jacking block moves, it drives the locking rod to move through the guide groove and the guide post.

[0012] In one possible implementation, the three bubble generating units include a connecting pipe and bubble generators evenly arranged along its axial direction mounted on the top of the connecting pipe, and a protective assembly for protecting the bubble generators is also mounted on the connecting pipe.

[0013] In one possible implementation, both ends of the connecting pipes located on the upper and lower sides are rotatably connected to movable seats, and the connecting frame has guide grooves corresponding to the movable seats one by one; the connecting pipe located in the middle is fixedly connected to the connecting frame, and the remaining connecting pipes are slidably connected to the corresponding guide grooves through the movable seats, and the connecting pipes located on the upper and lower sides are all equipped with limiting members that are slidably connected to the guide grooves, the limiting members being used to limit the rotation of the connecting pipes.

[0014] In one possible implementation, the protective assembly includes two V-shaped flow guides symmetrically arranged on the connecting pipe along the width of the connecting frame. The V-shaped flow guides are used to guide the water in the reservoir during the reciprocating movement of the connecting pipe.

[0015] In one possible implementation, the guide groove has a Y-shape that extends vertically through both the upper and lower sides, and the side wall cross-section of the movable seat has a V-shape that matches the two inclined side walls of the guide groove.

[0016] In one possible implementation, the limiting member is a hook plate fixedly installed at the end of the connecting pipe, with the end of the hook plate away from the connecting pipe slidably connected to a corresponding guide groove.

[0017] In one possible implementation, the reciprocating drive unit includes two swing plates, the middle of which is rotatably sleeved on the middle connecting pipe. The swing plates are located on the side of the connecting frame away from the gate pier sidewall. The swing plates are provided with guide holes symmetrically arranged along their length direction. The two guide holes are slidably sleeved on the corresponding connecting pipes. The connecting frame is equipped with a drive assembly for driving the swing plates to reciprocate.

[0018] In one possible implementation, the drive assembly includes a connecting frame with connecting plates slidably connected to the side of the gate pier near the side wall. Both connecting plates are rotatably connected to a movable seat installed at the end of the lower connecting pipe. A hydraulic drive source (such as a waterproof hydraulic cylinder, specifically an existing waterproof hydraulic cylinder, also known as an underwater hydraulic cylinder) is installed on the connecting frame to drive the connecting plates to slide along the length of the connecting frame.

[0019] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. The anti-icing structure for reservoirs in high-altitude and cold regions designed by the present invention increases the coverage width of the bubbles by cooperating with the upper and lower three bubble generating parts and the reciprocating drive part. The three-layer bubble generating parts generate bubbles for water bodies at different depths, which can realize the longitudinal mixing and disturbance of the water body. In extremely cold weather, when the temperature difference between the upper and lower parts of the water body is large, it can also drive the water body at different depths to move, further promoting the heat exchange of the water body and greatly improving the anti-icing effect of the reservoir. In addition, the lifting and locking part can not only adjust the downward movement depth of the bubble generating mechanism, but also lock the position of the bubble generating mechanism after it has moved down, thereby improving the movement stability of the bubble generating mechanism during operation and preventing the bubble generating mechanism from moving and affecting the anti-icing effect when the reciprocating drive part drives the upper and lower two bubble generating parts to move.

[0020] 2. In this invention, the reciprocating drive unit drives the uppermost and lowermost bubble generating units to reciprocate and move alternately along the length of the connecting frame. This allows the uppermost bubble generating unit to prevent ice formation in the surface water, while the lowermost bubble generating unit prevents ice formation in the deeper water. Furthermore, the lateral reciprocating and alternating movement expands the overall ice prevention width. The middle layer bubble generating unit is fixedly installed, providing stable bubble disturbance in the longitudinal middle layer depth. This avoids the lateral ice prevention blind zone in the middle layer caused by the movement of the upper and lower bubble generating units, which would affect the ice prevention effect of the reservoir.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figure 1 and Figure 2 An ice-proof structure for a reservoir in a cold region includes: four fixed frames 3, two connecting frames 4, a bubble generating mechanism 5, and a storage and protection mechanism 6. The four fixed frames 3 are arranged in a matrix, with two fixed frames 3 in a group. The two groups of fixed frames 3 are respectively fixedly installed on the side walls of the gate piers 1 on both sides of the gate. A gate 2 is provided at the gate (the gate 2 and the control mechanism of the gate 2 are existing technologies, and the control mechanism of the gate 2 is not shown in the figure). The connecting frames 4 are slidably connected to the two fixed frames 3 installed on the same gate pier 1. The two connecting frames 4 are symmetrically arranged along the length of the gate 2.

[0032] See Figure 1 , Figure 2 and Figure 5The bubble generating mechanism 5 is installed between two connecting frames 4. The bubble generating mechanism 5 includes three bubble generating parts 50 arranged evenly from top to bottom between the two connecting frames 4. A reciprocating drive part 51 is provided between the two connecting frames 4. The bubble generating part 50 located in the middle is fixedly connected to the connecting frame 4. The other two bubble generating parts 50 move alternately along the length direction of the connecting frame 4 under the drive of the reciprocating drive part 51. A lifting locking part 52 is also provided between the two connecting frames 4 to drive it to move up and down and lock the connecting frame 4. The lifting locking part 52 cooperates with the reciprocating drive part 51 and the three bubble generating parts 50 to adjust the anti-icing width and anti-icing depth.

[0033] See Figure 1 The storage and protection mechanism 6 is installed between the tops of the gate piers 1 on both sides of the gate and is located on top of the bubble generating mechanism 5. The storage and protection mechanism 6 is used to store the bubble generating mechanism 5.

[0034] During operation, the lifting and locking unit 52 drives the two connecting frames 4 to move the three bubble generating units 50 downwards into the water. The depth of the bubble generating unit 5 entering the reservoir is determined according to the water level. After the bubble generating unit 5 enters the water to the designated depth, the lifting and locking unit 52 locks the two connecting frames 4, and then the bubble generating unit 50 is started to work. The bubble generating unit 50 releases a large number of tiny bubbles into the water. As the bubbles rise, they drive the water to circulate up and down, transporting the bottom warm water to the surface, breaking the inversion layer, and keeping the surface water temperature above freezing. At the same time, the bubble disturbance can prevent ice nuclei from forming and inhibit ice growth.

[0035] It should be noted that each bubble generator 50 can operate independently. One, two, or three bubble generators 50 can be activated, with adjustments made according to temperature changes in cold regions. When the risk of freezing increases, all three bubble generators 50 and the reciprocating drive unit 51 can be activated simultaneously to increase the bubble coverage. The specific operating process is as follows: During the operation of the bubble generators 50, the reciprocating drive unit 51 is activated. The reciprocating drive unit 51 drives the uppermost and lowermost bubble generators 50 along the length of the connecting frame 4. The bubble generators move back and forth in a staggered manner in the vertical direction. The uppermost bubble generator 50 is used for ice prevention in the surface water (areas prone to freezing), while the lowermost bubble generator 50 is used for ice prevention in the deep water (areas storing warm water). Through the staggered movement in the horizontal direction, the horizontal ice prevention range can be dynamically adjusted, forming a "complementary coverage" in the horizontal direction and expanding the overall ice prevention width. The middle layer bubble generators 50 are fixedly connected, which can provide stable bubble disturbance in the vertical middle layer depth, avoiding the horizontal ice prevention blind zone in the middle layer caused by the movement of the upper and lower bubble generators 50, thus affecting the ice prevention effect of the reservoir.

[0036] The three bubble generating units 50, one above the other, work in conjunction with the reciprocating drive unit 51 to increase the coverage of the bubbles. The three-layer bubble generating units 50 generate bubbles for water at different depths, which can achieve longitudinal mixing and disturbance of the water. In extremely cold weather, when there is a large temperature difference between the upper and lower parts of the water, it can also drive the water at different depths to move, further promoting the heat exchange of the water and further improving the anti-icing effect of the water. Compared with the traditional single fixed position bubble generating device, it can cover the area to be iced more comprehensively and efficiently, greatly improving the anti-icing effect of the reservoir.

[0037] Specifically, the connecting frame 4 has a rectangular structure. On the side of the connecting frame 4 closest to the gate pier 1, there are two slots symmetrically arranged along its length. The fixing frame 3 has protrusions that slide in cooperation with the slots.

[0038] See Figure 1 and Figure 2 The storage and protection mechanism 6 includes a fixed cover 60 connected to the top of the gate piers 1 on both sides of the gate opening. The fixed cover 60 has a pick-and-place slot 61 in the middle, and the pick-and-place slot 61 has a drive source on both sides to drive the connecting frame 4 to move up and down.

[0039] Specifically, the driving source is an existing rope pulling device (such as a motor and a rope connected to the connecting frame 4, which pulls and lowers the connecting frame 4). Based on the weight of the entire bubble generating mechanism 5 and the buoyancy of the water, a counterweight can be added to the connecting frame 4 to facilitate the entire bubble generating mechanism 5 entering the water. The take-up and put-down slot 61 can also be equipped with a flip-up cover (not shown in the figure) to seal the top of the take-up and put-down slot 61 and protect the bubble generating mechanism 5.

[0040] See Figure 3 , Figure 4 , Figure 5 and Figure 6 The lifting and locking part 52 includes a mounting base 520 evenly arranged along its length on the top of the connecting frame 4, and the width of the mounting base 520 in the middle is greater than the width of the other two mounting bases 520. A bidirectional hydraulic cylinder 521 is mounted on the mounting base 520 in the middle, and a locking rod 522 is slidably mounted on the other two mounting bases 520. Both ends of the bidirectional hydraulic cylinder 521 are equipped with a pushing assembly that drives the corresponding locking rod 522 to move. Two sets of arc-shaped supports 526 are installed on the side wall of the gate pier 1. Each set of arc-shaped supports 526 consists of multiple arc-shaped supports 526 evenly arranged from top to bottom. Two arc-shaped supports 526 are also installed on the side wall of the gate pier 1 near the top, arranged along its length. The arc-shaped protrusion of the arc-shaped support 526 faces away from the gate 2. The locking rod 522 cooperates with the corresponding arc-shaped support 526 to lock the up and down movement of the connecting frame 4.

[0041] See Figure 3 , Figure 4 , Figure 5 and Figure 6 The pushing assembly includes a pushing block 523 installed on both telescopic ends of a bidirectional hydraulic cylinder 521. A receiving groove is provided on a mounting base 520 on which a locking rod 522 is installed. The pushing block 523 slides into the receiving groove. A guide post 524 is installed on the locking rod 522. A guide groove 525 is provided on the pushing block 523 to slide and cooperate with the guide post 524. When the pushing block 523 moves, it drives the locking rod 522 to move through the cooperation of the guide groove 525 and the guide post 524.

[0042] Depending on the ambient temperature, when the reservoir does not require ice prevention, the drive source moves the entire bubble generating mechanism 5 upward into the fixed cover 60, thereby storing the bubble generating mechanism 5. This avoids the need to disassemble and remove the ice prevention structure every time it is not in use, which increases the workload and affects the safety of the operators.

[0043] It should be noted that the bidirectional hydraulic cylinder 521 is an existing waterproof bidirectional hydraulic cylinder, also known as an underwater hydraulic cylinder.

[0044] When the bubble generating mechanism 5 needs to work, the drive source drives the bubble generating mechanism 5 into the water. After reaching a certain depth, the locking rod 522 aligns with the corresponding arc-shaped support 526. Then, the bidirectional hydraulic cylinder 521 is activated, which drives the push block 523 to move. The push block 523, through its guide groove 525, cooperates with the guide column 524 to drive the locking rod 522 to move towards the side wall of the gate pier 1 and abut against the side wall of the gate pier 1. At the same time, the locking rod 522 is inserted into the arc-shaped support 526. The arc-shaped support 526 limits the upper and lower movement of the locking rod 522 and the left and right movement of the connecting frame 4 by the fixing frame 3, thereby locking the position of the entire bubble generating mechanism 5. This improves the stability of the bubble generating mechanism 5 during operation and prevents the entire bubble generating mechanism 5 from moving and affecting the anti-icing effect when the reciprocating drive unit 51 drives the upper and lower bubble generating units 50 to move.

[0045] See Figure 2 and Figure 6 The three bubble generating units 50 include a connecting pipe 501 and bubble generators 502 uniformly arranged along its axial direction and mounted on the top of the connecting pipe 501. A protective component 503 for protecting the bubble generators 502 is also installed on the connecting pipe 501.

[0046] It should be noted that the bubble generator 502 is existing technology, and its specific working principle will not be described in detail.

[0047] See Figure 2 , Figure 3 , Figure 5 and Figure 6 Both ends of the connecting pipe 501 located on the upper and lower sides are rotatably connected to the movable seat 504. The connecting frame 4 is provided with guide grooves 505 corresponding to the movable seat 504. The connecting pipe 501 located in the middle is fixedly connected to the connecting frame 4. The other connecting pipes 501 are slidably connected to the corresponding guide grooves 505 through the movable seat 504. The connecting pipes 501 located on the upper and lower sides are all equipped with limiting members 506 that are slidably connected to the guide grooves 505. The limiting members 506 are used to limit the rotation of the connecting pipe 501.

[0048] The reciprocating drive unit 51 drives the uppermost connecting pipe 501 and the lowermost connecting pipe 501 to move back and forth alternately. During the movement, the connecting pipe 501 slides along the corresponding guide groove 505 by the limiting member 506 to prevent the connecting pipe 501 from rotating, so that the bubble generator 502 is always above the axis of the connecting pipe 501. At the same time, the moving seat 504 at the end of the connecting pipe 501 rolls along the corresponding guide groove 505 to reduce the friction between the connecting pipe 501 and the guide groove 505 during the movement, and improve the smoothness of the movement of the upper and lower connecting pipes 501.

[0049] See Figure 3 , Figure 5 and Figure 6 The protective component 503 includes two V-shaped flow guides 540 arranged symmetrically along the width direction of the connecting pipe 501. The V-shaped flow guides 540 are used to guide the water in the reservoir during the reciprocating movement of the connecting pipe 501 to prevent the water from impacting the bubble generator 502 and causing damage to the bubble generator 502.

[0050] See Figure 6 The guide groove 505 has a Y-shape that runs vertically through both the upper and lower sides to prevent small impurities in the water from getting stuck in the guide groove 505. The side wall cross-section of the movable seat 504 is V-shaped to match the two inclined side walls of the guide groove 505, so that the movable seat 504 can cooperate with the guide groove 505 and rotate and move along the guide groove 505. The cooperation between the movable seat 504 and the guide groove 505 improves the smoothness of the movement of the connecting pipe 501.

[0051] See Figure 6 The limiting member 506 is a hook plate fixedly installed at the end of the connecting pipe 501. The end of the hook plate away from the connecting pipe 501 is slidably connected to the corresponding guide groove 505, thereby limiting the connecting pipe 501 and preventing the connecting pipe 501 from rotating under the drive of the moving seat 504 when the reciprocating drive part 51 drives the connecting pipe 501 to move, which would affect the effect of the bubble generator 502 in generating bubbles.

[0052] See Figure 2 and Figure 6 The reciprocating drive unit 51 includes two swing plates 510. The middle part of the swing plate 510 is rotatably sleeved on the middle connecting pipe 501. The swing plate 510 is located on the side of the connecting frame 4 away from the side wall of the gate pier 1. The swing plate 510 has guide holes 511 symmetrically arranged along its length direction. The two guide holes 511 are slidably sleeved on the corresponding connecting pipes 501. The connecting frame 4 is equipped with a drive assembly for driving the swing plate 510 to reciprocate.

[0053] See Figure 2 and Figure 3 The drive assembly includes a connecting frame 4 with a connecting plate 530 slidably connected to the side of the gate pier 1. Both connecting plates 530 are rotatably connected to a movable seat 504 installed at the end of the lower connecting pipe 501. A hydraulic drive source 531 (such as a waterproof hydraulic cylinder, which is an existing waterproof hydraulic cylinder, also known as an underwater hydraulic cylinder) is installed on the connecting frame 4 to drive the connecting plate 530 to slide along the length of the connecting frame 4.

[0054] Start the hydraulic drive source 531. The hydraulic drive source 531 pushes the lower movable seat 504 to move through the connecting plate 530. The movable seat 504 drives the connecting pipe 501 to move along the length of the connecting frame 4. The lower connecting pipe 501 drives the swing plate 510 to rotate around the center of the middle connecting pipe 501. The lower connecting pipe 501 slides along the corresponding guide hole 511. During the rotation of the swing plate 510, the upper connecting pipe 501 is moved by the cooperation of the guide groove 505 and the guide hole 511. This realizes the function of the uppermost and lowermost connecting pipes 501 moving back and forth, thereby increasing the ice-proof width of the reservoir ice-proof structure.

[0055] See Figures 1-6 In specific operation, the lifting and locking unit 52 drives the two connecting frames 4 to move the three bubble generating units 50 downward into the water. The depth of the bubble generating unit 5 entering the reservoir is determined according to the water level. After the bubble generating unit 5 enters the water to the specified depth, the lifting and locking unit 52 locks the two connecting frames 4, and then starts the bubble generating unit 50 to work. The bubble generating unit 50 releases a large number of tiny bubbles into the water. During the rise of the bubbles, the water is circulated up and down, transporting the bottom warm water to the surface, breaking the inversion layer, and keeping the surface water temperature above the freezing point. At the same time, the bubble disturbance can prevent the formation of ice nuclei and inhibit the growth of ice layers.

[0056] Each bubble generator 50 can operate independently. One, two, or three bubble generators 50 can be activated, and their operation can be adjusted according to temperature changes in cold regions. When the risk of freezing increases, all three bubble generators 50 and the reciprocating drive unit 51 can be activated simultaneously to increase the coverage of the bubbles. The specific working process is as follows: During the operation of the bubble generators 50, the reciprocating drive unit 51 is activated. The reciprocating drive unit 51 drives the uppermost and lowermost bubble generators 50 to move back and forth alternately along the length of the connecting frame 4. The uppermost bubble generator 50 is used for ice prevention in the surface water areas that are prone to freezing, while the lowermost bubble generator 50 is used for ice prevention in the deeper water. Through the lateral reciprocating alternating movement, the lateral ice prevention range can be dynamically adjusted. The middle layer bubble generators 50 are fixedly connected and can provide stable bubble disturbance in the longitudinal middle depth, further improving the ice prevention effect.
