Description

Technical Field

[0001] The present invention relates to the field of low-temperature protection technology and equipment for water conservancy buildings, and in particular to an anti-ice shear protection system for a dam body. Background Art

[0002] For concrete dams located in extremely cold regions, when cold waves hit or in winter, the temperature gradient of the concrete on the upstream and downstream surfaces of the dam and the temperature difference between the inside and outside are very large. In order to reduce the temperature gradient on the dam surface, control the temperature stress on the dam surface, and prevent the occurrence of harmful cracks in the dam, the outer surface of the dam must be permanently insulated.

[0003] Currently, foam plastics are the main surface insulation materials used in dam construction. With appropriate measures, foam plastic boards can provide both thermal insulation and moisture retention. Foam plastics include polystyrene, polyethylene, polyurethane, polyvinyl chloride, phenolic formaldehyde, urea formaldehyde, and nitrogen urea.

[0004] Traditionally, polystyrene and polyurethane foams have been used for external insulation of dams. However, when exposed to sunlight and weathering, polystyrene and polyurethane foams will age, especially in areas with fluctuating water levels on the dam's waterfront in severe cold regions, where additional ice pressure, freezing, and ice pull are common.

[0005] Severely cold regions experience large annual temperature fluctuations, large diurnal temperature swings, and frequent cold snaps. This significant temperature difference between the inside and outside of dam concrete surfaces can easily cause surface cracks, some of which can develop into deep or penetrating cracks, threatening the integrity and durability of hydraulic structures. Currently, one of the key measures to prevent concrete cracks is strengthening insulation.

[0006] However, in severely cold regions, temperatures are low and the frozen layer is thick, typically exceeding 1.6 meters. Because the ice and dam are already frozen integrally, when the reservoir is supplying water or generating electricity, the water level drops and the ice sinks under its own weight. As it sinks, the ice frozen onto the dam's insulation creates a pullout force that tears the insulation, damaging it and exposing the RCC dam to the cold air. Furthermore, during RCC dam construction in severely cold regions, the upstream and downstream insulation layers are applied simultaneously, dissipating little heat from within the dam, leading to elevated temperatures. When the insulation tears and the concrete surface is exposed to the cold air, the temperature difference between the inside and outside of the dam is extreme, reaching as high as 45°C. This temperature difference generates tensile stresses exceeding the RCC dam's tolerances. This tensile stress can cause cracks in the concrete, sometimes even through-holes, leading to leakage, compromising operation and management and even endangering dam safety.

[0007] For example, projects in extremely cold regions often face ice shear damage to the dam's insulation layer, leading to water seepage. Frost heave can also cause severe leakage, necessitating costly grouting. Therefore, preventing ice shear damage to the insulation layer of RCC dams in these regions has become an urgent issue.

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention; it should be noted that in this application, for the convenience of description, the "left side" in the current view is referred to as the "first end", the "right side" is referred to as the "second end", the "upper side" is referred to as the "first end", and the "lower side" is referred to as the "second end". The purpose of such description is to clearly express the technical solution, and it should not be understood as an improper limitation on the technical solution of this application.

[0072] The present invention aims to solve the technical problem in the prior art that the dam body water level is frozen and causes ice shearing due to the rapid freezing speed, and provides an anti-ice shearing protection system for the dam body. Figure 1-5 As shown in FIG. 1 , the anti-ice pullout protection system for the dam body includes:

[0073] Multiple groups of protection system unit assemblies 100 are arranged at the water level of the water-facing surface 1 or the water-receiving surface 2;

[0074] Each group of protection system unit assemblies 100 is provided with symmetrically arranged floating airbag structures 101, which enable the protection system unit assemblies 100 to float at the water level; the floating airbag structures 101 of adjacent protection system unit assemblies 100 are connected by connecting ropes 4, so that multiple groups of protection system unit assemblies 100 are arranged in a row;

[0075] Each set of protection system unit components 100 includes: an elastic force release component 10, which can periodically generate a rebound force; a quadrilateral disturbance component 20, which can generate a deformation action after the rebound force and external force, and the quadrilateral disturbance component 20 includes an icebreaker plate 201. When the floating airbag structure 101 floats at the water level, the icebreaker plate 201 is located at the water level; wherein, the icebreaker plate 201 is connected to a balanced traction elastic component 30, and the balanced traction elastic component 30 is used to connect the floating airbag structure 101. The balanced traction elastic component 30 can buffer the traction force generated by the floating airbag structure 101 on the connecting rope 4 through the elastic traction part 301; the rebound force causes the deformation action of the quadrilateral disturbance component 20 to drive the icebreaker plate 201 to move, so as to destroy ice at the water level or prevent ice from forming at the water level.

[0076] The principle of preventing ice pull in this technical solution is to rely on destroying ice at the water level or periodically preventing the formation of ice at the water level. The floating airbag structure 101 constitutes the buoyancy arrangement in the system, and uses the rebound force generated by the elastic force release component 10 to cause the quadrilateral disturbance component 20 to deform, thereby driving the ice-breaking plate 201 to destroy the ice after the rebound force is generated and after being subjected to external force, thereby preventing the deep freezing of ice from producing ice pull.

[0077] In a specific embodiment, see Figure 2 、 3 As shown in Figures 4 and 5 ; the floating airbag structure 101 includes: a floating airbag body 101a, with protruding connecting portions 101b formed at both ends thereof, and a connecting ring portion 102 having a connecting end 103; the connecting end 103 is used to connect the connecting rope 4 or to connect the fixed end 330 of the balanced traction elastic component 30. The purpose of such a configuration is to enable the floating airbag structure 101 to obtain maximum buoyancy and reduce the influence of the attached connecting structure on its ability to obtain maximum buoyancy. At the same time, in order to ensure a stable connection and prevent it from falling off under the action of rebound force, a corrugated connecting portion 101c is constructed on the protruding connecting portion 101b in this technical solution; the corrugated connecting portion 101c is connected to the connecting ring portion 102, and the connecting ring portion 102 is wrapped around the corrugated connecting portion 101c.

[0078] In a specific embodiment, see Figure 2 、 3 As shown, the balancing traction elastic component 30 is arranged as a part below the liquid surface, specifically including: a main connecting part 310, a first end of which is connected to the bottom of the ice-breaking plate 201, and the other end of which is rotatably connected to a balancing hinge shaft 312 of a balancing hinge seat 311; two groups of balancing hinge rods 313 are symmetrically arranged and fixedly connected to both sides of the balancing hinge seat 311, and each group of balancing hinge rods 313 is connected to a group of elastic traction members 301.

[0079] The elastic traction member 301 includes: a traction connecting rod 301a, one end of which is rotatably connected to the balancing hinge rod 313, and the other end of which is inserted into a traction sleeve 301b and connected to a traction limit end 301c, a traction spring 301d is provided between the traction limit end 301c and the insertion opening of the traction sleeve 301b, and the traction spring is wound around the traction connecting rod 301a; the traction sleeve 301b is rotatably connected to a traction connecting seat 320 at one end away from the traction connecting rod 301a, and the traction connecting seat 320 is connected to the fixed end 330; in the above configuration, due to the balancing hinge shaft 312 and the main connecting part 310 As well as the connection method of the ice-breaking plate 201, when the ice-breaking plate 201 is subjected to external force, the entire balanced traction elastic component 30 will receive the conduction of the external force, so that the external force is gradually buffered under the conduction of the traction spring 301d. The purpose is to gradually weaken the influence of the external force when the impact is too large, so that the force of the system is gradually restored. When ice is unevenly frozen in the balanced traction elastic component 30, with the cooperation of the external force, the balanced traction elastic component 30 is also more likely to break the uneven freezing of the ice, thereby achieving an overall anti-ice pulling effect.

[0080] In a specific embodiment, see Figure 2 、 3 As shown, the quadrilateral disturbance assembly 20 includes: a main action shaft seat 210 having a main connecting shaft 211; a main action connecting rod 220, the second end of which is rotatably connected to the main connecting shaft 211; two sets of branch connecting rods 215, one end of which is simultaneously rotatably connected to the main connecting shaft 211 and the other end of which is respectively connected to a set of longitudinal connecting rods 212; a spring connecting column 213 perpendicularly connected to the center of the longitudinal connecting rod 212; a transverse spring 214, the two ends of which are respectively connected to a set of spring connecting columns 213; the lower end of each set of longitudinal connecting rods 212 is rotatably connected to an icebreaker connecting seat 230; the icebreaker connecting seat 230 is connected to the first surface of the icebreaker 201. The quadrilateral disturbance assembly 20 has a balanced state, in which the icebreaker 201, the branch connecting rods 215, and the spring connecting column 213 can remain parallel.

The electric cylinder 131 is mounted above a force applying sleeve 121 via a mounting bracket 132. The force applying sleeve 121 is provided with a communicating hole 122. The output end of the electric cylinder 131 is connected to a pushing member 132.

[0083] When the output end of the electric cylinder 131 is at its maximum stroke, the pushing component 132 can contact the force limiter 122 and compress the compression spring 123. When the output end of the electric cylinder 131 changes from the maximum stroke to the minimum stroke, the compression spring 123 releases the elastic force and pulls the main action connecting rod 220 to move in the first direction. The elastic force release assembly 10 also includes:

[0084] The force-applying mechanism 130 includes a gas impact tube 133, which is radially connected to the force-applying sleeve 121 via a coupling bracket 135 and arranged parallel to the force-applying sleeve 121. The first end of the gas impact tube 133 is connected to a solenoid valve 134, which is connected to a gas supply pipe 135. The gas supply pipe 136 extends toward the dam body and is connected to a gas source; the gas source is compressed air at a pressure of 0.45 MPa to 0.65 MPa. The second end of the gas impact tube 133 is connected to a gas nozzle 137. The icebreaker plate 201 is connected to a balancing traction elastic assembly 30, which is arranged below the icebreaker plate 201, offset from the centerline of the icebreaker plate 201.
