Description

Technical Field

[0001] This invention relates to the field of water slide technology, and in particular to a prefabricated water slide device adapted to existing weirs and dams. Background Technology

[0002] Currently, there are no dedicated water slides on the market suitable for existing weirs and dams in mountainous rivers. Traditional water slides require separate construction sites, resulting in low space utilization and failing to make use of existing weir and dam facilities. In addition, existing weirs and dams in mountainous areas have varying slopes and uneven surfaces, and the water level fluctuates greatly during the flood season, with strict flood control requirements. Therefore, water slides suitable for this scenario need to adopt a variable angle structure to flexibly match the original slope and surface shape of the weir and dam. At the same time, the modular and detachable splicing design facilitates on-site transportation, assembly, and posture fine-tuning, and can be quickly disassembled and moved during the flood season to ensure the normal flood discharge of the weir and dam. This is the inevitable choice for such sites.

[0003] However, existing variable-angle detachable water slides generally adopt a structure with direct hinges at the ends. Although angle adjustment and segmented assembly and disassembly can be achieved, the hinge position relies on a single point or narrow surface rotation connection. When the concave and convex angles on the surface of the dam are too large, the slide will form obvious bends at the angle change points, the transition curvature will change abruptly, the slope connection will not be smooth enough, and it will be easy to produce a bumpy and jerky feeling when sliding. Summary of the Invention

[0008] Preferably, the locking screw is provided with a plurality of axially extending guide grooves in the circumferential direction, and the inner walls of the positioning sleeve and the plurality of hexagonal sleeves are provided with a plurality of axial protrusions, the axial protrusions being slidably installed in the guide grooves.

A hexagonal positioning hole is provided on one side wall of the lower unit side plate and the middle unit side plate, which is concentric with the locking hole. The locking screw slides through the hexagonal positioning hole, the hexagonal locking hole, the arc-shaped groove and the locking hole on the other side. The positioning sleeve is inserted into the hexagonal positioning hole with a concave-convex fit. The hexagonal sleeve is locked in the hexagonal locking hole. The locking nut abuts against the outside of the locking hole on the other side wall.

[0010] Preferably, the arc-shaped insert plate is slidably inserted into the first insertion gap, the lower insertion base plate is slidably inserted into the second insertion gap, the middle guide beam is provided with hexagonal locking holes at intervals on one side, the side wall of the middle unit side plate is provided with a hexagonal positioning hole concentric with the locking hole, the locking screw slides through the hexagonal positioning hole, the hexagonal locking hole, the arc-shaped groove and the locking hole on the other side, the positioning sleeve is inserted into the hexagonal positioning hole with a concave-convex fit, the hexagonal sleeve is locked in the hexagonal locking hole, and the locking nut abuts against the outside of the locking hole on the other side wall.

[0011] Preferably, the top of the upper guide beam and the middle guide beam are provided with guide protrusions, and the bottom of the arc-shaped insert plate and the lower insert base plate are provided with guide grooves that slide in cooperation with the guide protrusions.

[0012] Preferably, the chute segment unit includes a chute base plate and chute side plates on the left and right sides of the chute base plate. The upper and lower ends of the chute base plate are provided with mutually engaging protruding bushings and positioning bushings.

[0015] The beneficial effects of the technical solution provided by this invention include: 1. In this invention, two assembly modes can be selected: a small arc-shaped turning segment component consisting of an upper arc-shaped unit and a lower arc-shaped unit spliced ​​together, and a large arc-shaped turning segment component consisting of an upper arc-shaped unit, several middle arc-shaped units, and a lower arc-shaped unit spliced ​​together. This is adapted to the needs of existing weirs and dams with different angles and slopes.

[0016] 2. In this invention, when the surface of the weir has an excessively large concave-convex angle, the turning section components are spliced ​​together. The sliding cooperation between the arc-shaped insert plates between the upper arc-shaped unit, the middle arc-shaped unit, and the lower insert base plate and the insert gap allows the turning section components to be adjusted at different angles. The arc-shaped sliding method makes the turning point smoother, avoids large angles, and ensures the overall smoothness of the water slide.

[0017] 3. In this invention, the locking nut and the positioning sleeve abut against both ends of the main body of the middle unit, and the locking screw is moved horizontally by tightening the thread of the locking nut. During the horizontal movement, the hexagonal sleeve slides into the hexagonal locking hole. The positioning sleeve and the hexagonal sleeve lock the main body of the middle unit and the upper guide beam in the circumferential direction, thereby locking the upper arc unit and the middle arc unit. Similarly, the middle arc unit and the lower arc unit are locked together, thereby locking the turning section assembly to a fixed turning angle to adapt to the concave and convex angles of the dam surface.

[0022] It can also be like Figure 3 As shown, the turning segment assembly 4 comprises an upper arc-shaped unit 41, a lower arc-shaped unit 43, a locking assembly 44, and several middle arc-shaped units 42.

[0023] like Figure 6 As shown, the upper arc-shaped unit 41 is composed of an integrally formed upper arc-shaped section and an upper direct section. The upper end of the upper direct section is provided with a positioning bushing 6 connected to the sliding groove section unit 2.

The upper overlapping base plate 412 is set in an arc shape and is integrally formed at the rear end of the upper unit body 411. The lower end of the upper overlapping base plate 412 is treated with a buffer slope. The upper guide beam 413 is set at the lower edge of the upper unit body 411 and extends parallel to the upper overlapping base plate 412. An insertion gap is provided between the upper arc-shaped guide rails 413 and between the upper overlapping base plates 412. An arc-shaped groove is provided in the middle of the upper guide beam 413. A guide protrusion is provided at the top of the upper guide beam 413. Several hexagonal locking holes are provided at intervals on one side of the upper guide beam 413. The hexagonal locking holes are interconnected with the arc-shaped groove.

[0024] like Figure 7 As shown, the lower arc-shaped unit 43 is composed of an integrally formed lower arc-shaped section and a lower direct section. The lower end of the lower direct section is provided with a protrusion bushing 5 connected to the sliding groove section unit 2. It includes a lower unit body 431 and a lower insertion base plate 432. The lower unit body 431 is provided with lower unit side plates on both sides. The lower part of the lower unit side plate is provided with a locking hole aligned with the arc-shaped groove. One side of the lower unit side plate is provided with a hexagonal positioning hole concentrically arranged with the locking hole. The lower side of the lower insertion base plate 432 is provided with a guide groove that slides and cooperates with the guide protrusion. The top of the lower direct section is provided with a protrusion bushing 5 that cooperates with the sliding groove side plate 22.

[0025] like Figure 5As shown, the central arc-shaped unit 42 includes a central unit body 421, an arc-shaped insert plate 422, a central overlapping base plate 423, and a central guide beam 424. The central unit body 421 is arc-shaped. The arc-shaped insert plate 422 and the central overlapping base plate 423 are integrally formed on the front and rear sides of the central unit body 421, respectively. The lower end of the central overlapping base plate 423 is treated with a buffer slope. The lower side of the arc-shaped insert plate 422 is provided with a guide groove that slides and cooperates with the guide protrusion. Central unit side plates are provided on both sides of the arc-shaped insert plate 422. The lower part of the central unit side plate is provided with a locking hole aligned with the arc-shaped groove. One side of the central unit side plate... The central unit body 4421 is provided with a hexagonal positioning hole concentric with the locking hole. The arc-shaped insert plate 422 and the middle overlapping base plate 423 are arc-shaped and integrally formed at the front and rear ends of the central unit body 4421. The central guide beam 424 is located at the lower edge of the central unit body 421 and extends parallel to the middle overlapping base plate 423. An insertion gap 2 is provided between the middle overlapping base plate 423 and the central guide beam 424. An arc-shaped groove is provided in the middle of the central guide beam 424. Several hexagonal locking holes are provided at intervals on one side of the central guide beam 424. The hexagonal locking holes are interconnected with the arc-shaped groove. A guide ridge is provided on the top of the central guide beam 424.

[0026] like Figure 8 As shown, the locking assembly 44 includes a locking screw 441, a locking nut 442, a positioning sleeve 443, and several hexagonal sleeves 444. A positioning ring 445 is fixed to one end of the locking screw 441. The locking nut 442 is threadedly fitted onto the other end of the locking screw 441. Several support rings 446 are threadedly connected to the middle of the locking screw 441. These support rings 446 can be screwed and fixed at any position on the locking screw 441 via threaded engagement, serving as support. Several axially extending rings are provided on the circumference of the locking screw 441. The guide groove has several axial protrusions on the inner walls of the positioning sleeve 443 and several hexagonal sleeves 444. The axial protrusions are slidably installed in the guide groove. The positioning sleeve 443 and several hexagonal sleeves 444 are slidably sleeved on the locking screw 441. The positioning sleeve 443 is slid to a position close to the positioning ring 445. A return spring 447 is connected between the positioning sleeve 443 and the positioning ring 445. Then, the support ring 446 and the hexagonal sleeves 444 are installed on the locking screw 441, and the hexagonal sleeves 444 are slid and abut against the support ring 446.

[0027] Example 1: like Figure 2 As shown, when adapting to the smaller slope of the existing weir, the turning section component 4 is composed of an upper arc-shaped unit 41, a lower arc-shaped unit 43, a locking component 44, and a wedge plate 45; The lower insertion base plate 432 of the lower arc-shaped unit 43 is slidably inserted into the insertion gap. The guide protrusion of the upper arc-shaped unit 41 is inserted into the guide groove of the lower arc-shaped unit 43. The upper overlapping base plate 412 of the upper arc-shaped unit 41 is slidably overlapping on the upper side of the lower unit body 431 of the lower arc-shaped unit 43. The guide groove limits the guide protrusion in the radial and left-right directions, and pulls the upper guide beam 413 tight at the bottom of the lower arc-shaped unit 43, so as to prevent the upper guide beam 413 of the cantilever beam structure from swaying left and right.

[0028] During assembly, the upper arc-shaped unit 41 and the lower arc-shaped unit 43 are slid together so that the hexagonal locking hole of the upper guide beam 413 aligns with the hexagonal positioning hole of the lower arc-shaped unit 43. The locking screw 441 is then passed through the hexagonal positioning hole, the hexagonal locking hole, the arc-shaped groove, and the locking hole to the other side of the lower unit side plate. The positioning sleeve 443 of the locking assembly 44 is engaged in the hexagonal positioning hole. With the support of the return spring 447, the locking screw 441 is positioned to the right. At this time, the hexagonal sleeve 444 is aligned with the hexagonal locking hole of the upper guide beam 413, and the locking screw is engaged. The locking nut 442 abuts against the lower unit side plate on the other side. Tightening the locking nut 442 prevents the locking screw 441 from rotating circumferentially due to the limiting effect of the guide groove and the positioning sleeve 443. Instead, the locking screw 441 slides horizontally to the right. During the sliding process, the hexagonal sleeve 444 slides to the right into the hexagonal locking hole to form a lock. The hexagonal sleeve 444 and the hexagonal locking hole form a positioning in the axial direction, thereby realizing the angle locking of the upper arc unit 41 and the lower arc unit 43, so that they maintain a fixed angle that is compatible with the small slope of the existing weir.

[0029] Example 2: like Figure 3-4 As shown, when adapting to the large slope of the existing weir, the turning section component 4 includes an upper arc-shaped unit 41, a lower arc-shaped unit 43, a locking component 44, and several middle arc-shaped units 42.

[0030] The arc-shaped insert plate 422 of the middle arc-shaped unit 42 is inserted into the insertion gap one. The guide protrusion of the upper arc-shaped unit 41 is inserted into the guide groove of the middle arc-shaped unit 42. The lower insertion base plate 432 of the lower arc-shaped unit 43 is slidably inserted into the insertion gap two. The guide protrusion of the lower arc-shaped unit 43 is inserted into the guide groove of the middle arc-shaped unit 42. The upper overlapping base plate 412 of the upper arc-shaped unit 41 is slidably overlapping on the upper side of the middle unit body 421 of the middle arc-shaped unit 42. The guide groove limits the guide protrusion in the radial and left-right directions to prevent the upper guide rail beam 413 and the middle guide rail beam 424 of the cantilever beam structure from swaying left and right. During the assembly process, the upper arc-shaped unit 41 and the lower arc-shaped unit 43 are slidably moved in the position of the middle arc-shaped unit 41. This allows the angle of the entire turning section assembly 4 to be adjusted so that it maintains a fixed angle that is compatible with the large slope of the existing weir.

[0031] During assembly, the upper arc-shaped unit 41 and the lower arc-shaped unit 43 are slid together so that the hexagonal locking hole of the upper guide beam 413 aligns with the hexagonal positioning hole of the lower arc-shaped unit 43. The locking screw 441 is then passed through the hexagonal positioning hole, the hexagonal locking hole, the arc-shaped groove, and the locking hole to the other side of the lower unit side plate. The positioning sleeve 443 of the locking assembly 44 is engaged in the hexagonal positioning hole. With the support of the return spring 447, the locking screw 441 is positioned to the right. At this time, the hexagonal sleeve 444 is aligned with the hexagonal locking hole of the upper guide beam 413, and the locking screw is engaged. The locking nut 442 abuts against the lower unit side plate on the other side. Tightening the locking nut 442 prevents the locking screw 441 from rotating circumferentially due to the limiting effect of the guide groove and the positioning sleeve 443. Instead, the locking screw 441 slides horizontally to the right. During the sliding process, the hexagonal sleeve 444 slides to the right into the hexagonal locking hole to form a lock. The hexagonal sleeve 444 and the hexagonal locking hole form a positioning in the axial direction, thereby realizing the angle locking of the upper arc unit 41 and the lower arc unit 43, so that they maintain a fixed angle that is compatible with the small slope of the existing weir.

[0032] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
