Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy and hydropower engineering, and particularly relates to a door beam of a flexible water gate and the flexible water gate. BACKGROUND

[0002] Large and medium-sized hydropower projects with high dams and large reservoirs have large reservoir capacity and deep reservoir water, which causes a certain degree of change in the spatial and temporal distribution of the original natural river water temperature. The water temperature in the reservoir generally forms a vertical distribution, with high surface temperature and low bottom temperature. The water intake of the water diversion and power generation system generally uses a deep hole for water intake. Therefore, the water temperature discharged at certain time periods is lower than that of the original natural river, which causes a certain degree of adverse impact on the downstream ecological environment. In addition, the friction between the steel beam in the traditional flexible curtain beam gate structure and the limiting groove is large during the folding and unfolding process, which affects the operation safety and makes it difficult to guarantee the timeliness of adjusting the water intake. Especially in high dams, the operation of the beam gate is complex and the lifting height is large. For example, in the Jinsha River Xiluodu Hydropower Station, 90 times of leaf lifting are required for the operation of one layer of beam gate.

[0003] Among them, the current flexible water gate layered water intake device, such as the one disclosed in the Chinese patent No. CN118326912A, is mainly composed of a frame main beam and flexible leaves. The folding and stretching of the flexible leaves are realized by the sliding cooperation of the water gate assembly and the door groove structure. This design enables the water gate assembly to be folded and stretched in the water level elevation direction, thereby adjusting the water intake depth and water intake opening. However, the sliding friction between the water gate frame main beam and the door groove results in large opening and closing resistance, and the self-locking problem is prone to occur during operation.

DETAILED DESCRIPTION

[0017] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in conjunction with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0018] The technical solutions disclosed by the various embodiments of the present application will be described in detail below in conjunction with the drawings.

[0019] Please refer to Figures 1 to 7 It is shown that the disclosed door beam 100 is provided with a guide portion 160 at the position close to each end portion of the front side and the rear side, respectively, the guide portion 160 is used for limiting movement cooperation with the guide groove of the limiting guide rail 221 in the gate pier door groove 220, and the side away from the door beam 100 of the guide portion 160 is provided with a rolling member 161, the rolling member 161 is used for rolling cooperation of the guide portion 160 with the guide groove; the position close to each end portion of the door beam 100 is also provided with a group of roller assemblies 190, the roller assemblies 190 are all located on the same side of the door beam 100, that is, as Figure 1 It is shown that the roller assemblies 190 are all located on the front side of the door beam 100, or all located on the rear side of the door beam 100, and are close to the corresponding guide portion 160 of the side, respectively, the roller assemblies 190 are used for rolling cooperation with the outer side wall of the limiting guide rail 221.

[0020] Among them, the first part of the limiting structure is formed by the rolling cooperation of the roller assembly 190 with one side of the outer wall of the limiting guide rail 221, which can not only limit the guide portion 160 to prevent collision and friction between the guide portion 160 and the guide groove of the limiting guide rail 221, but also form a two-part limiting structure with the second part of the limiting structure formed by the guide portion 160 and the guide groove of the limiting guide rail 221, so as to better ensure the movement of the door beam 100 along the limiting groove of the limiting guide rail 221, prevent the collision between the door beam 100 and the gate pier door groove 220, and the roller assembly 190 also has the advantage of small friction; and the rolling member 161 can effectively reduce the friction when the guide portion 160 moves along the limiting groove of the limiting guide rail 221.

[0021] Therefore, compared with the existing flexible water gate structure design, the door beam 100 structure disclosed in the embodiment can well ensure the running track of the door beam 100, effectively prevent the deformation and damage of the door beam 100, the gate pier door groove 220 and the limiting guide rail 221, ensure the stability and reliability of the flexible water gate operation, and has the advantages of simple structure, convenient operation and maintenance and small opening and closing assistance, thereby ensuring the timeliness of adjusting the water inlet.

[0022] Specifically, as shown in Figure 2 The guide part 160 can be provided in a square pad or gasket structure, and the rolling member 161 can be two rolling shafts arranged at intervals in the width direction of the door beam 100, which are respectively located on both sides of the central position of the guide part 160, and the axis of the rolling shaft is perpendicular to the guide part 160 and arranged along the moving direction of the limiting guide rail 221, thereby ensuring the smooth movement of the guide part 160 along the limiting groove of the limiting guide rail 221.

[0023] Meanwhile, as shown in Figure 3 and Figure 4 The rolling wheel assembly 190 can include a mounting seat and a rolling wheel 170, the mounting seat is arranged perpendicular to the length direction of the door beam 100, and the length of the mounting seat is greater than the width of the door beam 100, both ends of the mounting seat are located outside the door beam 100, and the rolling wheel 170 is rotatably arranged at both ends of the mounting seat, respectively, so that the two rolling wheels 170 correspond to the positions outside the door beam 100, which is beneficial to reduce the gap between the door beam 100 and the limiting guide rail 221, better guarantee the stability of the movement of the door beam 100 along the limiting guide rail 221, and facilitate the arrangement of the water stop structure; at the same time, the two rolling wheels 170 can form balanced rolling support above and below the guide part 160, further improving the stability of the operation of the door beam 100.

[0024] Preferably, as shown in Figure 2 and Figure 3 The mounting part is an angle steel structure 180, the angle steel structure 180 is arranged towards the corresponding guide part 160, one side plate of the angle steel structure 180 is fixed with the door beam 100, and the rolling wheel 170 is rotatably arranged at both ends of the side plate, respectively, and the other side plate of the angle steel structure 180 is away from the guide part 160, so as to play a protective role for the rolling wheel 170 inside the angle steel structure 180 and the structure of the limiting guide rail 221.

[0025] More preferably, as shown in Figure 3 The angle steel structure 180 is located inside the guide part 160, that is, on the side of the guide part 160 away from the pier door slot, compared with the structure that the angle steel structure 180 is arranged outside the guide part 160, the depth design of the pier door slot 220 can be reduced, thereby facilitating the construction and installation of the door beam 190 and the maintenance and replacement of the rolling wheel assembly 190 and other operations; it is easy to understand that the rolling wheel 170 can be detachably connected with one side plate of the angle steel structure 180 through a bolt structure, thereby facilitating the installation and disassembly operation of the rolling wheel 170.

[0026] Based on the above-mentioned door beam 100 structure, the present embodiment also discloses a flexible water-blocking door, which can include a plurality of door beams arranged in sequence along the water level elevation direction, and as shown in Figure 1As shown, the door beam adopts the door beam 100 structure of the above embodiment, and the flexible door leaf 110 is arranged between the two adjacent door beams 100, so that the folding and draining and the stretching and water blocking of the flexible door leaf 110 are realized through the relative and opposite operation of the two adjacent door beams 100; generally, the flexible door leaf 110 can be selected from the existing high-strength curtain.

[0027] Meanwhile, as shown in Figure 3 and Figure 4 , the inner walls of the two sides of the gate pier slot 220 are respectively provided with the limiting guide rails 221 extending in the vertical direction, the limiting guide rails 221 protrude from the inner walls of the gate pier slot 220, the limiting parts 160 are respectively located in the guide grooves of the corresponding limiting guide rails 221 and are limited and rolled in the guide grooves through the rolling members 161, so as to reduce the friction between the guide parts 160 and the guide grooves, and the rolling assembly 190 is rolled with one side of the outer wall of the limiting guide rail 221, so as to limit and guide the movement of the guide part 160 along the guide groove.

[0028] Preferably, as shown in Figure 1 , the rolling assemblies 190 of the two adjacent door beams 100 are located at the opposite sides of the door beam 100, which is more conducive to the balanced operation of the flexible water-blocking door compared with the setting that the rolling assemblies 190 of all the door beams 100 are located at the same side of the door beam 100. Among them, the limiting guide rails 221 can be arranged at the slot positions adjacent to the gate pier slot 220, the rolling assembly 190 is located at the side of the guide part 160 away from the limiting guide rail 221, and the rolling assembly 190 is located outside the gate pier slot 220, so as to facilitate the maintenance and replacement of the rolling assembly 190 and the like.

[0029] Generally, in order to ensure the water-stopping effect of the flexible door leaf 110, the flexible door leaf 110 can be arranged as a water-stopping structure that is attached to the gate pier wall surface 200 towards the two sides of the gate pier slot 220, and the water-stopping structure is a structure made of rubber material, so as to ensure the smooth operation of the folding and stretching of the flexible door leaf 110.

[0030] The flexible water-blocking door disclosed in the embodiment can also be provided with an abutting member at the position of the two side edges of the door beam 100 adjacent to the flexible door leaf 110, and the abutting member is located at the side of the door beam 100 where the flexible door leaf 110 is located; when the flexible door leaf 110 is in the stretched state, the abutting member abuts against the side edge part of the flexible door leaf 110, so as to reduce the risk of increasing the upstream and downstream leakage caused by the deformation or movement of the flexible door leaf 110, effectively improve the water-stopping effect of the flexible door leaf 110, and further ensure the stable water temperature of the layered water and the safe operation of the project.

[0031] As shown in Figure 5As shown, as an implementable mode of the abutting member, the abutting member is a link structure; two ends of the link structure are connected with two adjacent door beams 100 respectively, and the link structure has an unfolded state and a folded state; when the flexible door leaf 110 is in the folded state, the connecting structure is also rotated to the folded state; when the flexible door leaf 110 is in the unfolded state, the link structure is rotated to the unfolded state and abuts against the side edge part of the flexible door leaf 110, so as to avoid deformation and movement of the side edge of the flexible door leaf 110, keep the flexible door leaf 110 in effective contact with the pier wall surface 200, strengthen the water stopping effect at the side edge of the flexible door leaf 110, and more effectively adjust the water level in front of and behind the water-blocking building to improve the discharged water temperature.

[0032] Wherein, the link structure at two ends of the adjacent door beams 100 can also limit and guide the folding and unfolding of the door beams 100 and the flexible door leaf 110, ensure that the door beams 100 fold and unfold the flexible door leaf 110 in the rotation plane of the first link 120 and the second link 130, so as to better reduce the risk of friction and collision between the door beams 100 and the pier door groove 220, and avoid the problems of strength reduction caused by deformation of the door beams 100 and water leakage and imbalance caused by damage of the door groove.

[0033] In addition, the link structure can also support the door beams 100 and the flexible door leaf 110, and when the flexible door leaf 110 is partially damaged or torn, the link structure can support the self-weight of the door beams 100 and the flexible door leaf 110, thereby reducing the force on the flexible door leaf 110 and reducing the risk of further damage to the flexible water-blocking door.

[0034] It should be noted that when the flexible door leaf 110 is in the unfolded water-blocking state, the first link 120 and the second link 130 are unfolded, and the included angle thereof is less than 180°, which can be seen from Figure 5 Thus, the unfolded first link 120 and the unfolded second link 130 do not affect the rotation and folding of the first link 120 and the second link 130, so as to ensure the smooth folding of the flexible door leaf 110.

[0035] Therefore, the sum of the lengths of the first link 120 and the second link 130 can be designed to be greater than the height of the unfolded flexible door leaf 110; at the same time, the sum of the lengths of the first link 120 and the second link 130 is less than or equal to the length of the door beam 100, so that the link structure can meet the operation requirements of the unfolded flexible door leaf 110 and avoid mutual interference of the first link 120 and the second link 130 when they are rotated and folded, thereby affecting the folding of the flexible door leaf 110.

[0036] Preferably, at least one of the first link 120 and the second link 130 is provided with an elastic extension structure; during the movement of the two adjacent door beams 100 along the pier door groove 220 towards or away from each other, when the left and right ends of the door beam 100 appear to be unbalanced in force during the lifting movement along the pier door groove 220, the elastic extension structure can play a buffering role to make the first link 120 and / or the second link 130 adaptively extend and contract, so as to ensure the balanced operation of the door beam 100 and avoid the tilting and self-locking phenomenon caused by the unbalanced operation of the door beam 100.

[0037] As an implementable mode of the elastic extension structure, as shown in Figure 6 , the elastic extension structure can be a spring structure 150; at the same time, a hinge 140 can be arranged at the other end of the first link 120, a second guide hole 131 adapted to the hinge 140 is arranged at the other end of the second link 130, and the second guide hole 131 extends along the length direction of the second link 130; the hinge 140 passes through the second guide hole 131 and is in sliding fit with the second guide hole 131; one end of the spring structure 150 is fixedly arranged on the second link 130, and the other end of the spring structure 150 is connected with the hinge 140.

[0038] When the left and right ends of the door beam 100 are unbalanced in force, the first link 120 and the second link 130 make the hinge 140 adaptively move along the second guide hole 131 through the elastic extension of the spring structure 150, so as to realize the adaptive adjustment of the first link 120 and the second link 130 to maintain the balanced operation of the door beam 100.

[0039] More preferably, as shown in Figure 6 , a first guide hole 121 can also be arranged at the other end of the first link 120, and the first guide hole 121 extends along the length direction of the first link 120; the hinge 140 passes through the first guide hole 121 and the second guide hole 131 and is in sliding fit with the first guide hole 121 and the second guide hole 131, so that the hinge 140 can adaptively move along the first guide hole 121 and the second guide hole 131 through the elastic extension of the spring structure 150, so that the adaptive adjustment of the first link 120 and the second link 130 is more flexible, and the balanced operation of the door beam 100 is better maintained.

[0040] It is easy to understand that the hinge 140 can be a bearing structure, so that not only the friction force of the relative rotation of the first link 120 and the second link 130 can be reduced, but also the bearing structure has high structural strength to ensure the support of the link structure to the door beam 100 and the flexible door leaf 110.

[0041] Specifically, as shown in Figure 5 and Figure 6As shown, the outer ring of the bearing structure is connected with a first guide part, the inner ring of the bearing structure is connected with a second guide part, the first guide part passes through the first guide hole 121 and is connected with the first limiting part, the second guide part passes through the second guide hole 131 and is connected with the second limiting part; usually, the first guide part and the second guide part are both provided as screw rod structures, and the first limiting part and the second limiting part are both provided as nut structures which are tightly matched with the screw rod structures, so as to facilitate the assembly, disassembly and other operations of the first connecting rod 120, the second connecting rod 130 and the bearing structure.

[0042] Of course, as other implementable manners, the elastic telescopic structure can also be a spring structure to replace the spring structure 150 described above; or, the first connecting rod 120 and the second connecting rod 130 can also be provided as existing elastic telescopic rod structures; the hinge 140 described above can also be provided as an existing rivet or pin shaft structure.

[0043] In the embodiment, as another implementable manner of the abutting part, as shown in Figure 7 As shown, the abutting part can also be provided as a pressing piece 300; one end of the pressing piece 300 is fixedly connected with the door beam 100, and the other end of the pressing piece 300 is an elastic free end; when the side edge part of the flexible door leaf 110 is attached to the pier wall surface 200, the elastic free end of the pressing piece 300 is in a curved or bent state, used for abutting against the side edge part of the flexible door leaf 110 and generating an elastic force for pressing and attaching the side edge part of the flexible door leaf 110 to the pier wall surface, so as to avoid deformation and movement of the side edge of the flexible door leaf 110, keep the flexible door leaf 110 in effective contact with the pier wall surface 200, strengthen the water stopping effect at the side edge of the flexible door leaf 110, more effectively adjust the water levels in front of and behind the water-stopping building, and improve the discharged water temperature.

[0044] In order to ensure the water stopping effect of the side edge part of the flexible door leaf 110 to the pier wall surface 200, as shown in Figure 5 and Figure 7 As shown, a water stopping strip 210 can also be arranged on the pier, the water stopping strip 210 corresponds to the side edge part of the flexible door leaf 110 and is vertically arranged along the water level elevation direction; when the side edge part of the flexible door leaf 110 is attached to the pier wall surface 200, the edge thereof can abut against the water stopping strip 210, so that the water stopping strip 210 can better improve the water stopping effect of the side edge part of the flexible door leaf 110.

[0045] Preferably, a gap is arranged between the side of the weather strip 210 facing the side edge portion of the flexible door leaf 110 and the pier, for the side edge of the flexible door leaf 110 to be embedded, and the height of the gap is less than the thickness of the side edge of the flexible door leaf 110, so that the gap formed between the weather strip 210 and the pier wall surface 200 can ensure the close fit of the side edge portion of the flexible door leaf 110 with the pier wall surface 200, and the side edge portion of the flexible door leaf 110 can be uniformly pressed, ensuring the water sealing effect of the entire side edge portion of the flexible door leaf 110, and the side edge portion of the flexible door leaf 110 can also withstand the lateral water pressure without deformation and displacement, keeping the straightness of the side edge portion of the flexible door leaf 110, which not only ensures the water sealing effect, but also avoids the deformation and displacement of the side edge portion of the flexible door leaf 110 affecting the orderly folding of the flexible door leaf 110, thereby ensuring the safe operation of the flexible water isolation building.

[0046] It is easy to understand that the above gap is preferably designed in a flared structure, i.e. the height of the gap gradually decreases from the entrance of the gap to the inside of the gap, so that the flared structure can make the side edge portion of the flexible door leaf 110 more easily embedded in the gap; specifically, the weather strip 210 can be a rubber rod, and the cross-sectional shape of the rubber rod is circular or elliptical, so that when the circular or elliptical rubber rod is fixedly arranged on the pier wall surface 200, it can be tangent to the surface of the pier to form a gap with a flared structure.

[0047] The above embodiments of the present application mainly describe the differences between the embodiments, and the different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory. Considering the brevity of the text, further description is omitted here.

[0048] The above only describes the embodiments of the present application and is not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
