Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective equipment for hydraulic structures in cold regions, specifically a guide ice and flexible energy dissipation protective structure for hydraulic structures in cold regions. Background Technology
[0002] Hydraulic structures in cold regions refer to structures built in cold climate areas for water resource development and utilization (such as water supply, irrigation, hydropower generation, etc.) and water conservancy projects such as flood control, tide control, and ice control. These regions usually have long cold seasons, and water bodies such as rivers and lakes are prone to freezing and freeze-thaw phenomena; for example, dams, sluices, and aqueducts.
[0003] In cold regions, dams not only have to withstand conventional loads such as water pressure and soil pressure, but also ice pressure. For example, when the surface of a reservoir freezes, the expansion of the ice layer will generate static ice pressure on the dam; when ice blocks move, they will also generate dynamic ice pressure. To cope with these situations, the slope protection materials and structures of dams in cold regions may be more robust and able to resist the friction and impact of ice; the panel design thickness of concrete-faced rockfill dams may be appropriately increased to take into account the impact of ice loads.
[0004] In cold regions, sluice gates and other components are susceptible to ice damage. The upstream and downstream of the sluice gate may experience abnormal water level changes due to ice blockage and ice dam formation. To prevent the gates from freezing, heating devices are usually installed or special gate sealing materials are used to ensure that the gates can be opened and closed normally. In addition, the design of the sluice gate's inlet and outlet shapes may also take into account guiding ice blocks to pass smoothly and reducing ice block accumulation.
[0005] An aqueduct is a hydraulic structure that transports water across obstacles such as valleys and rivers. In cold regions, if the water temperature inside the aqueduct is low, it may freeze on the aqueduct walls, affecting its water carrying capacity. Therefore, insulation measures for aqueducts in cold regions are very important. For example, insulation materials can be used to wrap the outer shell of the aqueduct to reduce heat loss and prevent the internal water from freezing. At the same time, the supporting structure of the aqueduct also needs to consider the impact of ice load on its stability.
[0006] Hydraulic structures in cold regions face numerous challenges, including ice pressure, ice jams, and ice dams. When rivers freeze, ice blocks move with the water flow, directly and frequently impacting dams, sluices, and aqueducts, causing collision damage to hydraulic structures in cold regions. Utility Model Content
[0007] The purpose of this invention is to provide a guiding ice and flexible energy dissipation protection structure for hydraulic structures in cold regions, so as to solve the defects mentioned in the background art.
[0008] To achieve the above objectives, a guiding ice and flexible energy dissipation protection structure for hydraulic structures in cold regions is provided, including a guiding plate. The surface of the guiding plate is provided with a positioning groove, and the front of the guiding plate is covered with an energy dissipation protection plate. A buffer seat is fixedly installed on the surface of the energy dissipation protection plate, and a docking groove is provided on the side of the guiding plate away from the positioning groove. An external connector is covered on the back of the guiding plate, and a docking strip is fixedly installed on the surface of the external connector. Multiple sets of equally spaced insertion pins are fixedly installed on the side of the external connector away from the docking strip. Four sets of through holes are evenly provided on the surface of the guiding plate.
[0009] Preferably, the energy dissipation protective plate is a rectangular structure made of plastic, and four sets of buffer seats are evenly arranged on the surface of the energy dissipation protective plate.
[0010] Preferably, the distance between two adjacent sets of buffer seats is the same, and the buffer seats are made of rubber with a semi-circular cross-section.
[0011] Preferably, the back of the energy dissipation and protection plate is provided with four sets of equidistant positioning strips, and the surface of the guide plate is provided with four sets of equidistant positioning grooves.
[0012] Preferably, the dimensions of the positioning groove and the positioning strip are matched, and the four sets of positioning strips are respectively inserted into the four sets of positioning grooves. At the same time, the cross-sections of the positioning groove and the positioning strip are both dovetail-shaped. The energy dissipation protection plate and the guide plate are positioned and installed through the positioning strip and the positioning groove.
[0013] Preferably, the back of the guide plate is provided with two sets of docking grooves, and two sets of docking strips are fixedly provided on the surface of the outer seat. At the same time, the two sets of docking strips are respectively inserted into the interior of the two sets of docking grooves. The cross-sections of the docking strips and the docking grooves are both dovetail-shaped.
[0014] Preferably, one end of the guide plate is provided with an assembly groove, and the other end of the guide plate is fixedly provided with an assembly strip. The size of the assembly strip is adapted to the size of the assembly groove, and the guide plates are assembled by inserting the assembly strip into the inside of the assembly groove. The cross-section of the assembly strip and the assembly groove are both "T" shaped.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the guide plate can guide the flow direction of ice blocks flowing on the water surface. At the same time, when ice blocks impact the surface of the soft buffer seat, the buffer seat deforms, which can weaken and buffer the impact force generated by the ice block impact, avoiding the situation where ice blocks directly and frequently impact hydraulic structures in cold regions, causing collision damage to the hydraulic structures in cold regions; when ice blocks impact the four sets of buffer seats, the buffer seats deform, and in this process, the buffer seats absorb part of the kinetic energy of the ice blocks, reducing the impact on hydraulic structures in cold regions.

[0021] Please see Figure 1-4 This utility model provides a guiding ice and flexible energy dissipation protection structure for hydraulic structures in cold regions, including a guiding plate 2. The surface of the guiding plate 2 is provided with a positioning groove 23, and the front of the guiding plate 2 is covered with an energy dissipation protection plate 1. At the same time, a buffer seat 11 is fixedly provided on the surface of the energy dissipation protection plate 1, and a docking groove 24 is provided on the side of the guiding plate 2 away from the positioning groove 23. The back of the guiding plate 2 is covered with an outer connecting seat 3, and a docking strip 31 is fixedly provided on the surface of the outer connecting seat 3. Multiple sets of equally spaced insertion pins 32 are fixedly provided on the side of the outer connecting seat 3 away from the docking strip 31. Four sets of through holes 25 are evenly provided on the surface of the guiding plate 2.
[0022] Working principle: The guide plate 2 has four sets of evenly spaced perforations 25. Through the perforations 25 and pins, the guide plate 2 can be fixed to the surface of a hard hydraulic structure. When the surface of the hydraulic structure is soil, the external connector 3 is inserted into the two sets of connecting grooves 24 on the back of the guide plate 2 via two sets of connecting strips 31, and numerous inserts 32 are inserted into the surface of the hydraulic structure. At this time, the energy dissipation protection plate 1 is inserted into the four sets of positioning grooves 23 via four sets of positioning strips 12, completing the positioning and installation of the energy dissipation protection plate 1 and the guide plate 2. The guide plate 2 guides the flow direction of ice blocks on the water surface. At the same time, when ice blocks impact the soft surface of the buffer seat 11, the buffer seat 11 deforms, which weakens and buffers the impact force generated by the ice block impact, avoiding direct and frequent impacts of ice blocks on hydraulic structures in cold regions, which could cause collision damage to the hydraulic structures in cold regions. When ice blocks impact the four sets of buffer seats 11, the buffer seats 11 deform. During this process, the buffer seats 11 absorb part of the kinetic energy of the ice blocks, reducing the impact on hydraulic structures in cold regions.
[0023] As a preferred embodiment, the energy dissipation protection plate 1 is a rectangular structure made of plastic, and four sets of buffer seats 11 are evenly arranged on the surface of the energy dissipation protection plate 1.
[0024] The distance between two adjacent sets of buffer seats 11 is the same, and the buffer seat 11 is made of rubber and has a semi-circular cross-section.
[0025] As a preferred embodiment, four sets of equidistant positioning strips 12 are evenly distributed on the back of the energy dissipation and protection plate 1, and four sets of equidistant positioning grooves 23 are evenly distributed on the surface of the guide plate 2.
[0026] The dimensions of the positioning groove 23 and the positioning strip 12 are compatible. The four sets of positioning strips 12 are respectively inserted into the four sets of positioning grooves 23. At the same time, the cross-sections of the positioning grooves 23 and the positioning strips 12 are all dovetail-shaped. The energy dissipation protection plate 1 and the guide plate 2 are positioned and installed through the positioning strips 12 and the positioning grooves 23.
[0027] As a preferred embodiment, the back of the guide plate 2 is provided with two sets of docking grooves 24, and two sets of docking strips 31 are fixedly provided on the surface of the outer seat 3. At the same time, the two sets of docking strips 31 are respectively inserted into the interior of the two sets of docking grooves 24. The cross-sections of the docking strips 31 and the docking grooves 24 are both dovetail shaped.
[0028] One end of the guide plate 2 is provided with an assembly groove 21, and the other end of the guide plate 2 is fixedly provided with an assembly strip 22. The size of the assembly strip 22 is adapted to the size of the assembly groove 21. The guide plates 2 are assembled by inserting the assembly strip 22 into the inside of the assembly groove 21. The cross-sections of the assembly strip 22 and the assembly groove 21 are both "T" shaped.
