Description

Technical Field

[0001] This utility model relates to the field of water entertainment facilities technology, specifically to an overflow drainage system and amusement facilities for aerial rafting amusement facilities, which is particularly suitable for water amusement scenarios that pursue shallow water depth, long-distance aerial rafting experience, and need to take into account operational stability and emergency safety. Background Technology

[0002] Among the rafting rides in water parks, aerial rafting is particularly popular due to its unique high-altitude floating experience. Existing aerial rafting rides generally rely on a "river slope combined with water depth" drive mode to ensure raft levitation and continuous movement across different sections. This means the raft is propelled by water flow generated by the slope, requiring a water depth greater than 250mm. To extend the length of the aerial rafting section, the water depth in subsequent sections needs to be further increased to maintain sufficient water flow, resulting in a significant increase in the total water volume. The supporting structures of the aerial rides (such as gantry frames and beams) must bear the weight of a large amount of water, significantly increasing manufacturing costs and construction difficulty. The excessive load also increases the risk of structural deformation and directly limits the design length of the aerial rafting section, failing to meet the demand for long-distance aerial rafting experiences.

[0003] Secondly, the drainage system design of existing aerial rafting facilities has significant shortcomings. Most of them adopt the method of "centralized drainage at the end of the river channel". This method has little impact on the operation of rafts in deep water scenarios. However, when trying to reduce the water depth to reduce the support burden, the small drainage outlet area and the fast local water flow will generate turbulence phenomena such as eddies and negative pressure in the river channel. This causes the rafts to be sucked into the vicinity of the drainage outlet by negative pressure and cannot drift forward normally. In addition, the existing drainage system lacks air pressure balance design. Air pressure fluctuations in the water tank or drainage pipes will further aggravate the water flow turbulence, seriously affecting the smoothness of the ride and becoming a key obstacle to the development of shallow and deep aerial rafting facilities.

[0004] Furthermore, the existing drainage system is not integrated with emergency response plans. In the event of a power outage or other emergencies, the drainage pipes will continue to discharge water, causing the water level in the river to drop rapidly. The rafts will lose their buoyancy due to lack of water and become stuck on the bottom. Tourists stranded in the elevated river at this time will be unable to push their rafts to safety, and if the river has a slope (the existing facilities have many slopes to drive the water flow), the risk of slipping and falling will increase, resulting in a serious lack of emergency safety assurance capabilities. Summary of the Invention

[0005] The purpose of this utility model is to provide an overflow drainage system and amusement facilities for aerial rafting rides. The overflow drainage system uses a water tank that is flush with the bottom of the aerial rafting river and has a drainage plate to receive the water below, which greatly expands the drainage contact area. With the help of an air pressure balance pipe that connects one end to the upper part of the water tank and the other end to the atmosphere, the air pressure inside and outside the water tank is effectively balanced, avoiding the vortex and negative pressure that are easy to be generated by traditional centralized drainage in shallow water and deep water scenarios, and preventing the raft from being sucked in and stuck. The amusement facilities that integrate this overflow drainage system, with the overall horizontal aerial rafting river, break through the limitation that the water depth increases sharply with the length of existing facilities, which can greatly reduce the total amount of water and reduce the load on the portal frame support structure.

[0006] This utility model is achieved through the following technical solution: An overflow drainage system for an aerial rafting amusement facility includes an aerial rafting river, drainage units, a drainage main, and an overflow main. The drainage units are spaced apart along the length of the aerial rafting river. The drainage main is located in a transition trough at the junction of the aerial rafting river and below the hoist at the junction. A solenoid valve is provided on the drainage main. A baffle plate is provided in the transition trough, and the baffle plate and the outer wall of the transition trough form a volume cavity communicating with the top of the transition trough. The overflow main communicates with the volume cavity. The drainage unit includes a water-leaking plate, a water tank, a drain pipe, and an air pressure balancing pipe. The water tank is located below the river channel of the aerial rafting river, and the water-leaking plate covers the inlet end of the water tank. One end of the drain pipe is connected to the water tank, and the other end is used to discharge water. One end of the air pressure balancing pipe is connected to the upper side of the water tank, and the other end is directly connected to the atmosphere.

[0007] In this design, drainage units are spaced out along the aerial drifting river. Water tanks are located below the river channel with inlet covers to increase the drainage contact area and prevent excessively rapid local water flow. A pressure balancing pipe, connected at one end to the top of the water tank and at the other to the atmosphere, balances the air pressure inside and outside the tank, preventing vortices and negative pressure from pulling the raft in shallow or deep water. The main drainage pipe is located in the transition trough at the connection point, below the hoist. Its solenoid valve can be locked in an emergency to stop drainage, maintaining the river level and preventing the raft from hitting the bottom. A vertical baffle plate in the transition trough forms a volumetric cavity with the outer wall of the trough. The overflow main pipe connects to this cavity, allowing only water exceeding the normal level to enter and then exit. This prevents unnecessary overflow due to normal water level fluctuations and ensures timely removal of excess water, guaranteeing stable river levels and smooth raft operation. Optionally, the drainage unit further includes a level switch located inside the air pressure balance pipe. The level switch is electrically connected to the valve of the drainage pipe and the solenoid valve of the main drainage pipe. When the river water level rises due to excessive water replenishment or the movement of the raft, the level switch can promptly trigger the valve of the drainage pipe to increase its opening, accelerating the discharge of water from the tank to lower the river water level. If the water level continues to rise, it can also control the solenoid valve of the main drainage pipe to remain open to assist in drainage, ensuring that the water level remains stable within a range suitable for the raft's floating, preventing the nozzle from being submerged or causing abnormal buoyancy of the raft. In case of emergency such as power outage, the level switch can quickly trigger the solenoid valve of the main drainage pipe to lock based on the water level signal, while simultaneously controlling the valve of the drainage pipe to close, preventing the continuous loss of river water from causing a sudden drop in water level, ensuring that the raft remains floating, and providing a safe environment for tourists to evacuate in emergencies.

[0008] Optionally, the system also includes a branch pipe and a switch valve. One end of the branch pipe is connected to the bottom of the transition trough, and the other end is connected to the overflow main pipe. The switch valve is located on the branch pipe. When the facility needs to be inspected, cleaned, or the water level in the transition trough needs to be quickly lowered, opening the switch valve allows the accumulated water and residual water at the bottom of the transition trough to be directly discharged into the overflow main pipe through the branch pipe, significantly shortening drainage time and improving operation and maintenance efficiency. In addition, if the water in the transition trough increases rapidly due to a sudden situation, and the conventional overflow from the baffle plate and the overflow main pipe is insufficient to quickly drain the water, opening the branch pipe can serve as an auxiliary drainage path to prevent water in the transition trough from overflowing to components such as the lifting machine at the connection point, further ensuring the flexibility and reliability of the overflow drainage system.

[0009] Optionally, it also includes a water supply pipe and nozzles. The water supply pipe is installed at the bottom of the river channel of the aerial rafting channel, and the nozzles spray water in the same direction along the river channel, which can provide continuous and unidirectional auxiliary thrust for the raft, ensuring that the raft moves smoothly in the horizontal river channel and avoids stagnation or jamming due to insufficient power.

[0010] An aerial rafting amusement facility includes a platform, a first river channel, an aerial rafting river channel, a connecting water slide, a second river channel, and an overflow drainage system. The aerial rafting river channel is horizontally arranged, and the overflow drainage system is connected to the aerial rafting river channel to drain the water in the aerial rafting river channel. The platform is used for passengers to board and alight and for raft transfer. One end of the first river channel is connected to the water area of ​​the platform, and the other end is connected to the inlet of the first lifting device. The outlet of the first lifting device is connected to the starting end of the aerial rafting river channel. The end of the aerial rafting river channel is connected to the inlet of the connecting water slide through the second lifting device. The outlet of the connecting water slide is connected to one end of the second river channel, and the other end of the second river channel is connected to the water outlet of the platform (1).

[0011] In this design, the aerial rafting river is horizontally designed, overcoming the limitations of existing facilities that rely on slope to drive water flow. This eliminates the need to increase water depth by extending the river's length, allowing for stable control of the water depth within a shallow range suitable for raft floating. This significantly reduces the total water volume and the load on the supporting structure of the aerial rafting river. Simultaneously, it allows for flexible extension of the river's length, providing tourists with a longer aerial rafting experience. Furthermore, the overflow drainage system connected to the aerial rafting river can promptly drain excess water, maintaining a stable water level and preventing turbulent flow or raft jamming in shallow or deep water conditions, ensuring a smooth rafting experience.

[0012] As an optional solution for aerial rafting amusement facilities, the first lifting device includes a first-stage lifting machine and a second-stage lifting machine. The first-stage lifting machine is located below the second-stage lifting machine along the height direction. The first-stage lifting machine is equipped with a speed adjustment device, which can flexibly adjust the interval between the rafts entering the second-stage lifting machine. This can not only avoid collisions and congestion caused by the rafts being too close, but also dynamically adapt the transport efficiency according to the actual passenger capacity of the horizontally set aerial rafting river, preventing rafts from piling up in the river or wasting transport capacity. A first transition groove is provided at the connection between the first lifting device and the aerial rafting river. The first transition groove is equipped with an inclined unpowered roller mechanism, a horizontal unpowered roller mechanism, and a water spray pipe. The interval at which the raft enters the second stage lifting machine is adjusted by the speed adjustment device. The water spray pipe applies forward auxiliary power to the raft, which, together with the inclined unpowered roller mechanism and the horizontal unpowered roller mechanism, smoothly enters the horizontally set aerial rafting river, avoiding the raft from getting stuck or overturning due to direct impact on the groove due to the height difference. The horizontal unpowered roller mechanism can further reduce the frictional resistance between the bottom of the raft and the transition groove.

[0013] As an optional solution for aerial rafting amusement facilities, the platform also includes a power area, a boarding area, a disembarking area, and an operating area; The power zone drives the rafts towards the launching area via a chain conveyor structure. The launching area is located in front of the power zone, and the launching area is located behind the power zone. The boarding and disembarking areas are spaced apart on one side of the power zone. This layout, where the boarding and launching areas are connected and the disembarking and launching areas are connected, effectively avoids congestion among tourists and improves the efficiency of boarding / disembarking and raft transfer. The operating area is located on the other side of the power zone, with a drive mechanism located below it. The drive mechanism is connected to the power zone via an inclined transmission shaft, and the axis of the transmission shaft is above the water surface of the first and second river channels. This completely isolates the water body physically, preventing water from flowing along the transmission shaft into the drive mechanism below the operating area and effectively preventing short circuits, corrosion, or component damage caused by water ingress.

[0014] As an optional feature of the aerial rafting amusement facility, the platform also includes a transfer area located on one side of the operating area. The transfer area is used for tourists to lift rafts from the ground rafting river to the power area, or for tourists to lift rafts from the power area to the ground rafting river. The transfer area provides tourists with a flexible switching path between the two modes of play: ground rafting and aerial rafting. Tourists can either lift their rafts to the transfer area and then transfer them to the power area to start the aerial rafting experience while playing on the ground rafting river, or after the aerial rafting is over, lift their rafts from the power area to the transfer area and then enter the ground rafting river to continue the play process. This breaks the limitations of existing aerial floating facilities, which are mostly independent operating units with fixed and single play paths.

[0015] As an optional solution for aerial rafting amusement facilities, the aerial rafting river is made of multiple sections of fiberglass spliced ​​together. The splices are connected by flange plates to ensure the sealing and structural strength of the splices and effectively prevent water leakage from the river. Furthermore, a support structure is provided beneath the aerial rafting river channel. This support structure includes multiple spaced-apart portal frames, each with two uprights and a crossbeam support. A flange plate is connected to the crossbeam support, forming a basic load-bearing unit. The connection between the flange plate and the crossbeam support evenly distributes the weight of the river channel to the portal frames, avoiding localized stress concentration. The uprights of adjacent portal frames are connected by crossbeams, with vertical and diagonal pipes between the crossbeams. Tie rods are provided between the two uprights of the same portal frame. This multi-directional reinforcement design significantly improves the stability of the support, resisting lateral forces and vertical loads generated by water fluctuations and raft movement in the aerial river channel, reducing the risk of structural deformation. The crossbeam support has pipe holes for water supply pipes to pass through and supply water to the nozzles, allowing the water supply pipeline to be integrated with the support structure without the need for additional pipeline supports.

[0016] As an optional solution for aerial rafting amusement facilities, an emergency system is also included, which includes an emergency power supply and emergency platforms spaced at intervals along the length of the aerial rafting river. The emergency power supply is electrically connected to the solenoid valves of the first lifting device, the second lifting device, and the overflow drainage system. When the power is off, the emergency power supply drives the first lifting device and the second lifting device to operate in reverse, transporting the stranded raft to a safe area on the ground, and drives the solenoid valve to lock to maintain the water level of the aerial rafting river, ensuring that the raft is always floating. This avoids the raft hitting the bottom and getting stuck, which would affect the evacuation of tourists, and also makes it convenient for tourists to push the raft to a safe area in the horizontally set aerial rafting river.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. The overflow drainage system of this utility model, by setting up a drain plate and a water tank, enlarges the drainage outlet area when the water in the river is discharged, compared to directly connecting the drain pipe to the river channel. This prevents eddies and other disturbances in the river channel, and avoids the raft being sucked in by negative pressure and unable to continue drifting. This is a problem that traditional aerial river channels do not consider, because they require greater water depth to operate, and drainage is often only at the deepest point at the end of the river channel. The greater water depth means that the upper water body is minimally or not affected, so those skilled in the art would not realize the problem of negative pressure affecting the raft. Simultaneously, this utility model also connects a pressure balancing pipe to the side of the water tank. During drainage, the air pressure inside the water tank can maintain a relatively stable balance with the external atmosphere through the pressure balancing pipe, further preventing suction on the raft in the aerial river channel. This is because the pressure balancing pipe directly connects the water tank to the atmosphere, making the water flow in the tank more stable during drainage, allowing it to drain steadily from the drain plate without creating eddies or other disturbances in the river channel. 2. This utility model also controls the water depth within a shallow water level suitable for raft floating by using a horizontally set aerial rafting channel. It does not rely on the slope, breaks through the limitation that the water depth increases sharply as the length increases, reduces the total water volume to reduce the load on the supporting structure, and can also flexibly extend the channel to provide a long-distance rafting experience. 3. The crossbeam of this utility model has upper and lower sections, with vertical and diagonal pipes between them to strengthen the structure. In addition, a tie rod is installed between the two columns of the same portal frame to further enhance the structural stability, and the tie rod can also serve as a supporting foundation for the pipeline; and the crossbeam support has pipe holes to allow the water supply pipe to pass through, which can support the water supply pipe and facilitate the water supply pipe to the nozzle, making the water supply and support well-organized and convenient for installation and maintenance.

Emergency Platform. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0021] This embodiment 1 provides an overflow drainage system for aerial rafting amusement facilities, such as... Figures 8-12 As shown, it includes a drainage unit, a drainage main pipe 84, and an overflow main pipe 86.

[0022] Among them, such as Figure 9 As shown, the drainage units are spaced apart along the length of the aerial drifting river 4. This embodiment has 4 groups, which can be increased or decreased according to the river length. Figures 10-12 As shown, each drainage unit includes a water supply pipe 41, a drain plate 491, a water tank 49, a drain pipe 44, and an air pressure balancing pipe 46. The water supply pipe 41 is laid along the length of the aerial rafting river 4 on one side of the riverbed, and sprays water in the same direction along the river through nozzles 42 to generate thrust, providing continuous and unidirectional auxiliary thrust for the raft. The drain plate 491 is made of corrosion-resistant stainless steel, with uniformly sized permeable holes on its surface, and the upper surface of the drain plate 491 is flush with the bottom surface of the aerial rafting river 4. The water tank 49 is a rectangular hollow structure, fixed to the support frame below the riverbed of the aerial rafting river 4, and the top inlet end of the water tank 49 is... Completely covered by the drainage plate 491, the water in the river slowly seeps into the water tank 49 by increasing the drainage contact area; one end of the drainage pipe 44 is connected to the drainage port 43 at the bottom of the water tank 49 through a flange, and the other end can be connected to the water treatment room of the amusement facility individually or in combination. In addition, the drainage pipe 44 is also equipped with an adjustable valve 48; the air pressure balance pipe 46 is a PVC round pipe, one end of which is connected to the upper side of the water tank 49 (10-15mm from the top of the water tank), and the other end is vertically upward and directly connected to the atmosphere, so as to avoid the formation of negative pressure in the water tank during drainage and reverse suction of the raft 7, thus solving the problem of vortex and raft suction caused by centralized drainage at the end in the prior art.

[0023] Specifically, the aforementioned drainage main pipe 84 is a corrosion-resistant steel pipe, such as... Figure 8 As shown, the second transition trough 83, which is connected at the end of the aerial rafting river 4, is laid at the bottom of the trough along its length and is located directly below the lifting mechanism 81 at the connection point. The inlet end of the drainage main pipe 84 is connected to the interior of the second transition trough 83, and the outlet end is connected to the water treatment room. A normally closed solenoid valve (which automatically locks when the power is off) is connected in series on the drainage main pipe 84. During normal operation, the solenoid valve is energized and opened, and the drainage main pipe 84 continuously discharges the water accumulated in the second transition trough 83, maintaining the water level of the transition trough consistent with that of the aerial rafting river 4. In case of emergency such as power failure, the solenoid valve is de-energized and automatically locks, blocking the drainage passage of the drainage main pipe 84, preventing the river water level from dropping suddenly, and ensuring that the raft 7 is always floating.

[0024] Meanwhile, a baffle plate 87 is connected to the side of the second transition trough 83 near the connecting water slide 5. The height of the baffle plate 87 is higher than the normal operating water level of the aerial drifting river 4 (in this embodiment, the normal water level is 180mm and the baffle plate height is 220mm). A closed volume cavity is formed between the baffle plate 87 and the outer wall of the second transition trough 83. The top of the volume cavity is connected to the top opening of the second transition trough 83. One end of the overflow pipe 86 is connected to the bottom of the volume cavity, and the other end is connected to the water treatment room to receive the overflow water in the volume cavity.

[0025] In some embodiments, to improve drainage efficiency, a branch pipe 85 is provided between the second transition channel 83 and the overflow main pipe 86. By controlling the switch valve, a portion of the water can be discharged to the overflow main pipe 86 when it is necessary to accelerate drainage.

[0026] In some embodiments, such as Figure 12 As shown, a level switch 492 is fixed inside the air pressure balancing pipe 46 of any drainage unit. The level switch 492 is a float-type level switch. The signal output terminal of the level switch 492 is electrically connected to the adjustable valve 48 of the drainage pipe 44 and the solenoid valve of the main drainage pipe 84. When the river water level rises, the water level in the air pressure balancing pipe 46 rises synchronously. When the water level rises to trigger the level switch 492, the valve 48 of the drainage pipe 44 can be opened more to accelerate drainage. When the water level drops, it returns to its original opening. In case of emergency such as power failure, the valve 48 can be closed directly. If a solenoid valve is installed, the water level of the entire aerial river can be maintained. Example 2

[0027] This embodiment 2 provides an aerial rafting amusement facility, including a platform 1, a first river channel 2, a first lifting device 3, an aerial rafting river channel 4, a second lifting device 8, a connecting water slide 5, a second river channel 6, a supporting structure, an emergency system, and the overflow drainage system described in embodiment 1. All structures form a closed-loop operating path, such as... Figures 1-12 As shown, the specific components are as follows: like Figures 1-4As shown, passengers board rafts 7 at platform 1. Platform 1 includes a power zone 10, a launching zone 11, a fading zone 12, a boarding zone 13, a disembarking zone 14, an operating zone 15, and an optional transfer zone. The power zone 10 uses a chain conveyor structure with anti-slip rubber mats on the chain surface. The launching zone 11 is located in front of the power zone 10 and contains a non-powered roller mechanism. The fading zone 12 is located behind the power zone 10 and contains a small hoist used to lift rafts 7 from the second river channel 6 to the power zone 10. The boarding zone 1... 3 is located on the same side of the power zone 10 at a distance of 1.5 to 2 meters from the drop-off area 14, and is equipped with anti-slip steps. The operation area 15 is located on the other side of the power zone 10, and a drive mechanism 102 is provided below it. The drive mechanism 102 is connected to the chain conveyor structure of the power zone 10 through an inclined drive shaft 101, and the axis of the drive shaft 101 is higher than the water surface of the first river channel 2 and the second river channel 6. The conversion area is located on the side of the operation area 15 away from the power zone 10, and the ground is covered with anti-slip mats for connecting the ground rafting river.

[0028] When the raft 7 flows through the first channel 2 and reaches the first lifting device 3, as Figures 5-6 As shown, the first lifting device 3 lifts the raft 7 to the aerial rafting river channel 4. The first lifting device 3 includes a first-stage lifting machine 30, a second-stage lifting machine 31, and a first transition trough 35. The first-stage lifting machine 30 is located below the second-stage lifting machine 31 along the height direction. The conveyor chain of the first-stage lifting machine 30 is equipped with a speed sensor and a frequency converter (forming a speed adjustment device). The first transition trough 35 is set at the connection between the first lifting device 3 and the aerial rafting river channel 4. It is located between the outlet end of the second-stage lifting machine 31 and the starting end of the aerial rafting river channel 4. The trough is equipped with an inclined unpowered roller mechanism 33 (inclination angle 15-20°) and a horizontal unpowered roller mechanism 34 in sequence. A water spraying mechanism 32 (the water spraying direction is consistent with the travel direction of the raft 7) is fixed on the trough wall.

[0029] Therefore, raft 7 enters the aerial drifting river channel 4, as... Figures 9-12 As shown, the aerial rafting river 4 is horizontally arranged and is composed of multiple fiberglass sections. The joints of adjacent river sections are connected by flange plates 47 bolts. A water supply pipe 41 is installed along the length of the river bottom. The water supply pipe 41 is equipped with nozzles 42 at intervals (the nozzles are oriented in the same direction as the raft 7 and the nozzle outlets are higher than the normal water level of the river). The drainage units in the overflow drainage system are distributed at intervals along the length of the aerial rafting river 4 to maintain the stability of the water level in the aerial rafting river 4.

[0030] When the raft 7 is propelled by the nozzle 42 to the end of the aerial drifting river channel 4, a second lifting device 8 is installed here, such as... Figure 8As shown, the second lifting device 8 includes a lifting mechanism 81, whose inlet end is connected to the end of the aerial rafting river 4 through the second transition groove 83 at the connection point of the aerial rafting river 4 and the connecting water slide 5. The second transition groove 83 is provided with a transition support plate 80, which is located below the lifting mechanism 81 and is used to support the raft 7 and the inclined unpowered roller mechanism 82. The inlet end of the connecting water slide 5 is located below the outlet end of the second lifting device 8, and the outlet end is connected to the starting end of the second river 6. The raft 7 is transported to the second river 6 through the second lifting device 8. One end of the second river 6 is connected to the outlet end of the connecting water slide 5, and the other end is connected to the water outlet area 12 of the platform 1. The first river 2 and the second river 6 are connected to each other below the platform 1 to form a water circulation channel. Finally, the raft 7 safely returns to the platform 1.

[0031] In this embodiment, the aerial rafting river channel 4 is horizontally erected at high altitude using a supporting structure. Therefore, for safety reasons, such as... Figures 9-12 As shown, the support structure includes multiple spaced portal frames, crossbeams 401, vertical pipes 403, inclined pipes 402, and tie rods 404. Specifically, each portal frame consists of two steel pipe columns 40 and a steel crossbeam support 45. The top of the crossbeam support 45 is provided with bolt holes that match the flange plate 47. The flange plate 47 of the aerial drifting river channel 4 is bolted to the crossbeam support 45. The columns 40 of adjacent portal frames are connected by two sections of crossbeams 401. Vertical pipes 403 and inclined pipes 402 are welded between the upper and lower crossbeams 401 (forming a triangular support). Tie rods 404 are provided between the two columns 40 of the same portal frame. Pipe holes are opened on the crossbeam support 45 for water supply pipes 41 to pass through, realizing the integration of water supply pipes 41 and the support structure, reducing space occupation, and facilitating maintenance.

[0032] In some embodiments, to further enhance device security, such as Figure 1 and Figure 7 As shown, it also includes an emergency system, which includes an emergency power supply, an emergency platform 9, and a pedestrian walkway 36. The emergency power supply is electrically connected to the solenoid valves of the first lifting device 3, the second lifting device 8, and the overflow drainage system. The emergency platform 9 is a steel platform, spaced along the length of the aerial rafting river 4. One side of each emergency platform 9 is connected to the interior of the aerial rafting river 4, and the other side is equipped with a rescue staircase (extending to the ground). The pedestrian walkway 36 is located on one side of the second section of the lifting machine 31 and extends to the ground along the height of the lifting machine. When the emergency power supply is cut off, it drives the first / second lifting device to reverse and transport the stranded rafts to a safe area on the ground. At the same time, the solenoid valves of the overflow drainage system automatically lock to maintain the river water level. The emergency platform 9 and the rescue staircase provide the nearest evacuation route for tourists in different locations, while the pedestrian walkway 36 facilitates rescue by staff or emergency evacuation of tourists.

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
