[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] The utility model provides an obstacle system for artificially building simulated rapids.

[0039] Figure 1 The schematic diagram of a water training ground can be used for rapids training for emergency rescue personnel, and can also be used for artificial entertainment parks in different locations where water sports can be carried out. Water sports include but are not limited to wakeboarding, kayaking, body surfing, surfboarding, bodyboarding, rafting, kayaking and any other water sports.

[0040] The training ground includes at least one reservoir 10, at least one pump station 20, at least one artificial river channel 30 and at least one obstacle system 40. The reservoir 10 is used to store the required water. The pump of the pump station 20 pumps water from the reservoir 10 to the highest point of the artificial river channel 30. Since the river channel has a certain slope to form a height difference, the water flows from high to low due to the effect of gravity, forming a certain flow rate. At the same time, by applying the principles of fluid mechanics and placing obstacle systems 40 of different heights and shapes, various complex water conditions are formed after the water flow hits the obstacle system 40. It should be noted that Figure 1 The illustration in the figure is not the only form of the present invention. When in use, the positions and quantities of the water reservoir 10, the pump station 20, the artificial river channel 30 and the obstacle system 40 can be adjusted according to the actual training needs.

[0041] Figure 2 4 is a perspective view of an artificially constructed river channel 30 including an obstacle system 40. As shown in the figure, the artificially constructed river channel 30 includes a base 31, a left wall 32 and a right wall 33. The base 31, the left wall 32 and the right wall 33 can be made of any of a variety of durable materials, such as concrete. The base 31 can be consistent with the layout of the mountain, wherein water generally flows in a downward direction, but for illustrative purposes, the base 31 is shown as a flat portion. The left wall 32 intersects with the base 31 at a certain angle (e.g., a right angle, or any other angle between vertical and horizontal) and is higher than the base 31; the specific height can be designed according to actual application needs. The right wall 33 is similar to the illustrated left wall 32. The base 31, the left wall 32 and the right wall 33 form a river channel 34 for carrying water in a downward direction. Although in Figure 2 The channel 34 is shown as being straight, but the channel 34 may be curved in one or more directions.

[0042] Figure 3 To include Figure 2 A perspective view of a plurality of grooved rails indicated at A in FIG. As shown in the figure, at least one first grooved rail 41 and at least one second grooved rail 42 are provided on the base 31 of the artificial river channel 30 .

[0043] See also Figures 4 to 5The first slotted track 41 includes a first back plate 410, and C-shaped or L-shaped first track walls 414 are integrally extended on both sides of the first back plate 410. The two first track walls 414 and the first back plate 410 form the first slotted track 41. The first slotted track 41 is embedded in the base 31, and can also be fixed to the base 31 through a first connector 411. As an embodiment, if the first slotted track 41 is embedded in the base 31, the upper surface of the first slotted track 41 is flush with the upper surface of the base 31. As an embodiment, if the first slotted track 41 is fixed to the base 31 through a first connector 411, at least one first fixing hole 413 can be provided on the first back plate 410 of the first slotted track 41. The first connector 411 passes through the first fixing hole 413, and the first connector 411 can be used in the prior art, such as an expansion bolt or a fixing bolt, to fix the first slotted track 41 to the base 31. As an embodiment, a plurality of first fixing holes 413 are provided according to the length of the first grooved track 41 to improve the fixing effect. As an embodiment, the first connecting member 411 can also be integrally formed on the first back plate 410 of the first grooved track 41 to be inserted into the interior of the base 31 to form a snap-fit ​​fixation. As an embodiment, a plurality of first grooved tracks 41 are laid, and a plurality of first grooved tracks 41 are arranged parallel and closely side by side on a horizontal plane. The specific number can be adjusted according to the needs of the actual site, including completely covering the base 31 of the artificially constructed river channel 30 or partially covering the base 31 on a horizontal plane. Based on the aforementioned embodiment, a plurality of first grooved tracks 41 are closely aligned with each other in the vertical direction, that is, the first track walls 414 of the front and rear first grooved tracks 41 in the vertical direction are aligned. The specific number can be adjusted according to the needs of the actual site, including completely covering the base 31 of the artificially constructed river channel 30 or partially covering the base 31 on a horizontal plane.

[0044] The second slotted track 42 is arranged above the first slotted track 41 and is perpendicular to the arrangement direction of the first slotted track 41. The second slotted track 42 includes a second back plate 420, and C-shaped or L-shaped second track walls 424 are integrally extended on both sides of the second back plate 420. The two second track walls 424 and the second back plate 420 form the second slotted track 42. As an embodiment, the second slotted track 42 can adopt the same structure as the first slotted track 41. As an embodiment, at least one second fixing hole 423 is provided on the second back plate 420 of the second slotted track 42.

[0045] The second slotted track 42 is fixed to the top of the first slotted track 41 through the second connecting member 421. As an embodiment, the second connecting member 421 can be a bolt or a rivet. The second connecting member 421 passes through the second fixing hole 423 to fix the second slotted track 42 to the top of the first slotted track 41. One end of the second connecting member 421 is engaged with the first track wall 414 of the first slotted track 41, and the other end is engaged with the second back plate 420. For example, if the second connecting member 421 is a bolt, the nut is clamped by the first track wall 414, and the corresponding nut is installed on the top of the second back plate 420. Based on this embodiment, the nut of the bolt can also be set to a shape that matches the first track wall 414.

[0046] like Figure 6 As shown, as another embodiment, in order to further improve the fastening between the second grooved track 42 and the first grooved track 41, a third connecting member 431 may be further provided above the second grooved track 42. The third connecting member 431 includes a fixing plate 4311. As a preferred embodiment, the fixing plate 4311 forms an interference fit with the second grooved track 42. The fixing plate 4311 integrally extends two support arms 4312, the support arms 4312 are substantially perpendicular to the fixing plate 4311, and the two support arms 4312 are in the same direction; each of the support arms 4312 integrally extends a fixing ear 4313, the fixing ear 4313 is substantially parallel to the fixing plate 4311, and extends outward by a certain distance; the fixing plate 4311 and the two fixing ears 4313 are respectively provided with through holes 4310. The second connecting member 421 may be bolts or rivets. The two second connecting members 421 pass through the through holes 4310 on the two fixing ears 4313, and the third connecting member 431 is detachably connected to the first grooved track 41, so as to form a detachable connection state between the second grooved track 42 and the first grooved track 41. For example, if the second connecting member 421 is a bolt, the nut or nut is clamped by the first track wall 414, and the corresponding nut or nut is installed above the fixing ear 4313. Based on this embodiment, the nut of the bolt can also be set to a shape that matches the first track wall 414.

[0047] As can be seen from the above-mentioned embodiments, the second grooved track 42 and the first grooved track 41 are arranged in a mutually perpendicular and relatively fixed manner. Compared with the technical solution in the prior art that only grooved tracks are arranged along the water flow direction of the artificially constructed river channel 30 to install obstacles, the utility model fixes the second grooved track 42 in a detachable manner on the first grooved track 41 arranged along the water flow direction of the artificially constructed river channel 30. On the one hand, it can greatly reduce the construction difficulty of setting the corresponding first grooved track 41 at the base of the artificially constructed river channel 30 according to the requirements of the design drawings. On the other hand, in the prior art, if the user proposes the requirement to adjust the position of the obstacle at will after installing the obstacle, the first grooved track 41 must be completely covered at the base 31 of the artificially constructed river channel 30 during the first construction, which virtually increases the construction difficulty and material usage, and the groove size of the first grooved track 41 also objectively has certain constraints on the placement of obstacles. The second grooved track 42 and the first grooved track 41 of the utility model actually constitute a plane coordinate. During the first construction, it is not necessary to completely cover the base 31 of the artificial river channel 30 with the first grooved track 41. The base 31 can be partially covered as needed. The aforementioned embodiment has a good fixing effect. The detachable second grooved track 42 can be set at will according to user needs and is not restricted by the groove size of the first grooved track 41, that is, the position of the obstacle can be set in an unconstrained continuous linear manner on the horizontal plane of the base 31.

[0048] Figures 6 to 11 4 is a perspective view of the installation of the obstacle assembly. As shown in the figure, the obstacle system 40 also includes at least one obstacle assembly 50 detachably connected to the second grooved track 42, and the obstacle assembly 50 includes at least one first fixing assembly 51, at least one obstacle 52 and at least one first support assembly 53. The first support assembly 53 is detachably connected to the first fixing assembly 51, and the obstacle 52 is detachably connected to the first fixing assembly 51 through the first fixing assembly 51.

[0049] The following is a detailed explanation of the various components of the obstacle system. It should be noted that the technical solutions of the various embodiments of the utility model can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] As an embodiment, the first fixing component 51 includes at least one mounting hole 510 and at least one mounting member 511, and the mounting member 511 passes through the mounting hole 510 to detachably connect the first fixing component 51 to the second grooved track 42. As an embodiment, the mounting member 511 is a bolt or a rivet. For example, if the mounting member 511 is a bolt, the nut is clamped by the second track wall 424, and the corresponding nut is installed on the upper side of the first fixing component 51. As an embodiment, the first fixing component 51 is a rectangular or square plate, and the mounting holes 510 are respectively provided at its four corners.

[0051] As an embodiment, the first support component 53 includes a support column 531, which can be a hollow or solid rod, and its material can be metal or high-strength plastic material. The cross-section of the support column 531 can be square, rectangular, circular or elliptical. As an embodiment, the upper and lower ends of the support column 531 are closed, and each end face is provided with a through hole 532 for being detachable to the first fixing component 51. As an embodiment, the upper and lower ends of the support column 531 are closed, and the lower end face is provided with a through hole 532 for being detachable to the first fixing component 51, and the upper end is provided with a screw extending outward. As an embodiment, the upper and lower ends of the support column 531 are closed, and each upper and lower end face is provided with a screw extending outward.

[0052] As an embodiment, the first fixing component 51 further includes a fixing hole 512 for detachably connecting the first supporting component 53. In this embodiment, the fixing hole 512 is used to cooperate with the screw or bolt, or cooperate with the through hole 532 together with a bolt or rivet to form a detachable connection.

[0053] like Figures 7 and 8As shown, as an embodiment, the obstacle 52 is a rectangular body or a square body, and the right angle can be a right angle or a chamfer to improve safety. The obstacle 52 includes a top 521 and a bottom 522 arranged oppositely, and the top 521 and the bottom 522 arranged oppositely pass through the left side and the right side arranged oppositely, and the front side and the rear side arranged oppositely; at least one through hole 520 is provided on the top 521 and the bottom 522 of the obstacle 52, and the first support component 53 passes through the through hole 520. As an embodiment, the shape of the through hole 520 matches the first support component 53. As an embodiment, the shape of the through hole 520 forms an interference fit with the first support component 53. Compared with the prior art, which is only stacked up and down obstacles 52, the utility model greatly improves the impact resistance of the obstacle system 40 by setting the first support component 53 that passes through the stacked obstacles 52. At the same time, if the obstacle 52 is partially damaged, it can be fixed in the original position as much as possible to prevent large obstacles from detaching and causing casualties.

[0054] As an implementation mode, the top 521 is provided with at least one fixing protrusion 5211, and a groove 5221 is provided at a corresponding position of the bottom 522, and the fixing protrusion 5211 matches the groove 5221 to achieve the fixing of two obstacles 52 when they are stacked up and down. As an embodiment, the fixing protrusion 5211 and the groove 5221 are symmetrically distributed at the four corners of the obstacle 52. As an embodiment, the fixing protrusion 5211 and the groove 5221 are both provided with drainage holes 5210 and 5220 that communicate with each other, so as to prevent the accumulated water on the obstacle 52 from corroding the obstacle 52 and producing moss or other aquatic organisms. As an embodiment, the fixing protrusion 5211 is a step, a round table or a spherical table with a cross-sectional area gradually decreasing from bottom to top, and correspondingly, the groove 5221 is also correspondingly set to a groove type matching the fixing protrusion 5211. This structure can guide and position the obstacles 52 when they are stacked, making it easier to install the obstacles 52. As an embodiment, the top 521 is provided with at least one strip-shaped protrusion 5213, and a strip-shaped groove 5223 is provided at a corresponding position of the bottom 522. The strip-shaped protrusion 5213 matches the strip-shaped groove 5223 to further enhance the fixing effect when two obstacles 52 are stacked up and down, and at the same time, the increase in the force-bearing surface can also disperse the external pressure and impact force on the obstacles 52. Preferably, the strip-shaped protrusion 5213 and the strip-shaped groove 5223 are arranged parallel to the front and rear sides of the obstacles 52.

[0055] As an embodiment, the top 521 of the obstacle 52 is also provided with at least one support groove 5215, which runs from the left side of the top 521 of the obstacle 52 to the right side of the top 521 of the obstacle 52, and passes through the through hole 520 of the top 521 of the obstacle 52. The obstacle assembly 50 also includes at least one second fixing assembly 54, which is arranged in the support groove 5215 to limit the movement of the obstacle 52 in the up and down directions. As an embodiment, the second fixing assembly 54 is a hollow or solid rod, or a sheet of material, and the rod or sheet is provided with a hole 540 to cooperate with the screw or screw at the upper end of the support column 531, or cooperate with a screw, bolt or rivet together with the through hole 532 of the support column 531, so as to fix the second fixing assembly 54 to the top of the support column 531. As an embodiment, the obstacle assembly 50 includes a plurality of obstacles 52 stacked up and down, and a corresponding number or more than one second fixing assembly 54 is respectively arranged in the support groove 5215 at the top of each layer of obstacles 52. At this time, a corresponding through hole is opened at the corresponding position of the support column 531 for the second fixing assembly 54 to pass through. This embodiment further enhances the relative stability of each layer of the stacked obstacles 52, and further enhances the overall stability and impact resistance of the obstacle system 50, and further reduces the risk of accidents caused by damage to the obstacles 52. As a preferred embodiment, the length of the second fixing assembly 54 is the same as the length of the support groove 5215 of the obstacle 52, so as to achieve the aforementioned technical effect to the greatest extent.

[0056] It can be seen from the above description that the obstacles 52 can be stacked from top to bottom to increase the height of the obstacle system 50, and the obstacles 52 can also be extended and laid horizontally to increase the width of the obstacle system 50, and the first fixing component 51 and the first supporting component 53 can be increased accordingly. Obviously, the size of the second fixing component 54 can be increased to match it. Of course, the obstacles 52 can also be extended and laid horizontally to increase the thickness of the obstacle system 50, and the first fixing component 51 and the first supporting component 53 can be increased accordingly.

[0057] As an embodiment, the obstacle 52 is a triangle. Preferably, the triangle is a right-angled triangle, and the right angle can be a right angle or a chamfer to improve safety. The triangular obstacle 55 is usually arranged on the left and right sides of the obstacle system 50. The triangular obstacle 55 also has the same structure as the aforementioned rectangular or square body, but the difference is that at least one supporting groove 5515 at the top of the triangular obstacle 55 extends from the right-angle side of the top of the triangular obstacle 55 toward the hypotenuse and passes through the through hole 550 at the top of the triangular obstacle 55, and does not form a through hole like the aforementioned rectangular or square body structure. The advantage of this method is to prevent the aforementioned second fixing component 54 from breaking and detaching from the obstacle system, while reducing the possibility of water flowing into the obstacles 52 and 55.

[0058] However, the triangular obstacle 55 can be arranged in the middle, that is, obstacles 52 of other shapes can be arranged on both sides of the triangular obstacle 55. In this case, the support groove 5515 runs from the right angle side of the top of the triangular obstacle 55 to the hypotenuse, and passes through the through hole 550 of the top 551 of the triangular obstacle 55.

[0059] As an embodiment, the triangular obstacle 55 also has a rectangular or square fixing and mounting structure, that is, it also has fixing protrusions, grooves, strip-shaped protrusions and strip-shaped grooves.

[0060] like Fig.11 As an embodiment, the obstacle system 50 further includes a cover plate 60, which is disposed on the top of the obstacle 52 or the triangular obstacle 55, and whose shape matches the shape of the obstacle.

[0061] The cover plate 60 includes a top and a bottom arranged oppositely, and the top and the bottom arranged oppositely pass through a left side and a right side arranged oppositely, and a front side and a rear side arranged oppositely; at least one through hole 600 is provided at the top and the bottom of the cover plate 60, and the first support component 53 passes through the through hole 600. As an embodiment, the shape of the through hole 600 matches the first support component 53. As an embodiment, the shape of the through hole 600 forms an interference fit with the first support component 53. As an embodiment, the bottom of the cover plate 60 is provided with a groove 6021 corresponding to the aforementioned fixing protrusion 5211, and the fixing protrusion 5211 matches the groove 6021 to achieve the fixing of the obstacles 52, 55 and the cover plate 60 when stacked up and down. As an embodiment, the grooves 6021 are symmetrically distributed at the four corners of the cover plate 60. As an embodiment, the groove 6021 is provided with a drainage hole 6020 communicating with the drainage holes 5210 and 5220. As an embodiment, the bottom of the cover plate 60 is further provided with a strip groove 6023 matching the strip protrusion 5213. As an embodiment, the top of the cover plate 60 is also provided with at least one supporting groove 6015 for accommodating the second fixing component 54. Since there is no protrusion on the top of the cover plate 60, the surface is relatively smooth, which reduces the water flow resistance, and the absence of protrusions on the surface also reduces the risk of injury when a person hits the obstacle system 40.

[0062] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
