Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to an intelligent underground flood drainage device for theme parks in water-rich environments. Background Technology

[0002] With the rapid development of the theme park industry, some theme parks are located in typical water-rich environments due to landscape design requirements or site selection characteristics. The underground spaces of these parks have long faced the risks of rainwater accumulation, flood backflow during the flood season, or daily water infiltration. Underground drainage systems have become the core infrastructure to ensure the structural safety of park facilities, the safety of visitor passage, and the normal operation order.

[0003] Currently, in the industry, the demand for underground drainage devices in theme parks in water-rich environments has been upgraded from "basic drainage" to a complex demand of "safety, precision, and durability": on the one hand, it needs to cope with the high frequency and high volume of drainage scenarios in water-rich environments, and on the other hand, it needs to match the theme park's requirements for operational economy and environmental protection.

[0004] Existing devices are mostly flood discharge structures with fixed openings, which cannot adaptively adjust the discharge volume and are difficult to cope with complex flood discharge scenarios. When facing torrential rain and floods, the fixed opening may lead to groundwater accumulation due to insufficient flood discharge capacity; when facing light rain accumulation, excessive flood discharge may cause the water flow pattern to deteriorate. Secondly, the lack of waterproof protection design makes the transmission components easy to be damaged and fail, and the movement may be stuck due to water ingress, corrosion, or silt blockage. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent underground flood discharge device for theme parks in water-rich environments, which solves the problems of the inability to adaptively adjust the flood discharge volume and the lack of waterproof protection design.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent underground drainage device for theme parks in water-rich environments, comprising a motor and a ball screw. A waterproof fixing plate with a chamfered structure is installed in front of the motor. A bearing seat is provided in front of the waterproof fixing plate. The waterproof fixing plate and the bearing seat are connected by a transition fit. Through holes are provided on both sides of the waterproof fixing plate. The ball screw passes through the through holes of the waterproof fixing plate and is connected to the inside of the device. A screw protective cover is fitted on the outside of the ball screw. The ball screw and the screw protective cover are connected by a ring joint. Connecting rods are fixedly connected to both ends of the ball screw. Adjusting plates are installed at both ends of the connecting rods. A drain hole is provided on the left side of the adjusting plate.

[0007] As a further description of the above technical solution: the end of the connecting rod is provided with a groove, and the inner walls on both sides of the groove are provided with threads, and a bolt passes through the threads. The connecting rod and the adjusting plate are detachably connected through the groove and the bolt.

[0008] As a further description of the above technical solution: a flange is installed at the front end of the waterproof fixing plate, and flange holes are evenly opened around the circumference of the flange. The included angle between two adjacent flange holes is 60 degrees. The waterproof fixing plate and the flange are connected by hexagonal bolts. A boss is welded on the side of the flange away from the waterproof fixing plate.

[0009] As a further description of the above technical solution: a protective cover connecting plate is installed on one end of the boss facing the outside of the device, the boss and the protective cover connecting plate are connected by rivets, and the outer surface of the protective cover connecting plate is electroplated with a waterproof membrane.

[0010] As a further description of the above technical solution: a pad is provided at the joint between the bearing housing and the waterproof fixing plate, and a hexagonal screw is provided on the right side of the pad. The hexagonal screw passes through the pad and is threaded to the bottom end of the bearing housing.

[0011] As a further description of the above technical solution: a worm gear shaft is inserted inside the bearing housing, the outer diameter of the worm gear shaft is the same as the inner diameter of the bearing housing, a bearing is installed at the connection between the left end of the worm gear shaft and the bearing housing, and worm teeth are integrally formed on the outer circumferential surface of the middle part of the worm gear shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotational motion is converted into linear motion by a motor-driven worm gear shaft, the worm gear and the ball screw working together, which drives the adjustment plate to move flexibly. When the water level exceeds the limit, the opening of the flood discharge hole on the adjustment plate is adjusted according to the size of the flood. When the flood is large, the flood discharge hole is fully opened to quickly discharge the flood. When the flood is small, the water is precisely controlled by opening part of the flood discharge hole, so as to avoid backflow of water or deterioration of water flow, ensure the safety of underground facilities and visitor passage in the theme park, and significantly improve the economic and environmental benefits of the theme park in the water-rich environment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4This utility model provides an embodiment of an intelligent underground drainage device for a theme park in a water-rich environment, comprising a motor 3 and a ball screw 4. The motor 3 provides the power source and is controlled by an external intelligent liquid level detection device. A chamfered waterproof fixing plate 8 is installed in front of the motor 3, and a bearing seat 7 is provided in front of the waterproof fixing plate 8. The waterproof fixing plate 8 and the bearing seat 7 are connected by a transition fit. The chamfered waterproof fixing plate 8 serves as the main support base of the device and provides a stable installation space for transmission components such as the worm gear shaft 13 and the worm gear 11 through the transition fit. Through holes are provided on both sides of the waterproof fixing plate 8, and the ball screw 4 passes through the through holes of the waterproof fixing plate 8 and is connected to the inside of the device. The ball screw 4 passes through the through holes of the waterproof fixing plate 8 and serves as the core load for the rotational to linear motion. The ball screw 4 is fitted with a screw protective cover 9 on its outer side. The ball screw 4 and the screw protective cover 9 are connected by a ring joint. The screw protective cover 9 provides initial protection for the ball screw 4, preventing it from directly contacting water / humid air. Connecting rods 5 are fixedly connected to both ends of the ball screw 4. Adjusting plates 1 are installed at both ends of the connecting rods 5. A drain hole 2 is opened on the left side of the adjusting plate 1. The ball screw 4 is connected to the adjusting plate 1 through the connecting rods 5, transmitting the linear motion of the screw to the adjusting plate 1, forming the execution end for adjusting the opening degree of the flood discharge outlet. The chamfered structure of the waterproof fixing plate 8 and the transition fit with the bearing seat 7 take into account both installation convenience and connection sealing, adapting to the installation requirements of underground water-rich environments. Through the synergy of the adjusting plate 1 and the ball screw 4, the limitations of traditional fixed-opening flood discharge are broken, providing a structural prerequisite for precise adjustment of the flood discharge opening degree.

[0025] Specifically, the end of the connecting rod 5 has a groove, and the inner walls on both sides of the groove have threads, through which bolts 6 pass. The connecting rod 5 and the adjusting plate 1 are detachably connected through the groove and the bolts 6. If the adjusting plate 1 is worn or aged due to water flow impact during operation, or if it needs to be replaced with a different specification of adjusting plate 1 according to the size of the flood discharge outlet, the two can be quickly separated by removing the bolts 6 without disassembling the entire transmission structure. This avoids the need to replace the entire device due to partial damage to the adjusting plate 1, and only the adjusting plate 1 needs to be replaced, reducing maintenance costs during the operation of the theme park. Different sealing levels or sizes of adjusting plates 1 can be replaced according to the flood discharge needs of different seasons in a water-rich environment, enhancing the flexibility of the device.

[0026] Specifically, a flange 17 is installed at the front end of the waterproof fixing plate 8. Flange holes 18 are evenly distributed around the circumference of the flange 17, and the included angle between two adjacent flange holes 18 is 60 degrees to ensure uniform force distribution and enhance the connection stability between the fixing plate and the bearing seat 7, avoiding loosening of the connection due to long-term water flow impact. The waterproof fixing plate 8 and the flange 17 are connected by hexagonal bolts. A boss 19 is welded on the side of the flange 17 away from the waterproof fixing plate 8. The boss 19 provides support for the installation of the protective cover connecting plate 10 and forms a stepped protection to reduce the path of water directly seeping into the bearing seat 7. Combined with the sealing of the bolt connection, it reduces the risk of groundwater seeping into the internal transmission cavity and protects core components such as the worm gear shaft 13 and the worm gear 11.

[0027] Specifically, a protective cover connecting plate 10 is installed on the end of the boss 19 facing the outside of the device. The boss 19 and the protective cover connecting plate 10 are connected by rivets. The outer surface of the protective cover connecting plate 10 is electroplated with a waterproof membrane to isolate humid air and groundwater vapor, prevent metal parts such as flange 17 and bolts from rusting, and extend the service life of connecting parts such as flange 17 and boss 19.

[0028] Specifically, a pad 15 is provided at the joint between the bearing housing 7 and the waterproof fixing plate 8 to increase the support contact area of ​​the bearing housing 7 and prevent local deformation of the bearing housing 7 due to concentrated force. A hexagonal screw 16 is provided on the right side of the pad 15. The hexagonal screw 16 passes through the pad 15 and is threaded to the bottom end of the bearing housing 7. This prevents the joint between the bearing housing 7 and the fixing plate from loosening during the operation of the device and reduces the shaking of the worm gear shaft 13 when it rotates in the bearing 12.

[0029] Specifically, a worm gear shaft 13 is installed inside the bearing housing 7. The outer diameter of the worm gear shaft 13 is the same as the inner diameter of the bearing housing 7, ensuring that the worm gear shaft 13 rotates without clearance in the bearing housing 7 and avoids power loss. A bearing 12 is installed at the connection between the left end of the worm gear shaft 13 and the bearing housing 7 to reduce the frictional resistance when the worm gear shaft 13 rotates and reduce the load on the motor 3. The outer circumferential surface of the middle part of the worm gear shaft 13 is integrally formed with worm teeth 14.

[0030] Specifically, a worm gear 11 is meshed directly below the worm gear 14, converting the rotational motion of the worm gear shaft 13 into the rotational motion of the worm gear 11. A through hole is provided at the center of the worm gear 11, through which the ball screw 4 passes. The nut on the ball screw 4 is fixedly connected to the worm gear 11 by screws. When the worm gear 11 rotates, it drives the nut to rotate synchronously, converting the rotational motion into the linear reciprocating motion of the ball screw 4, which drives the connecting rod 5 and the adjusting plate 1 to move, thereby realizing the adjustment of the opening of the flood discharge port.

[0031] Specifically, the lead screw protective cover 9 is composed of a spring and polyester fabric. The ring connecting the lead screw protective cover 9 and the ball screw 4 is made of rubber and fits tightly against the outer circumference of the ball screw 4. The spring can adapt to the linear extension and contraction of the ball screw 4, without affecting the movement of the lead screw. The polyester fabric is water-resistant and corrosion-resistant, isolating the lead screw from water and air erosion. The rubber ring fits tightly against the outer circumference of the ball screw 4, preventing water from seeping in through the gap between the protective cover and the lead screw, further sealing and protecting it, and preventing the lead screw from failing due to water ingress, corrosion, or mud and sand blockage in water-rich environments.

[0032] Working principle: During the application of this utility model, the waterproof fixing plate 8 is installed at the underground flood outlet, the motor 3 is mounted at the upper end of the flood outlet away from the water source, and the adjusting plate 1 is close to the flood outlet. After the intelligent liquid level detection device detects that the water level exceeds the safety threshold, the motor 3 is started. The motor 3 drives the worm gear shaft 13 to rotate under the support of the bearing 12. The worm gear 14 of the worm gear shaft 13 meshes with the worm wheel 11, causing the worm wheel 11 to rotate. Since the ball screw 4 nut is fixed to the worm wheel 11, the rotation of the worm wheel 11 causes the ball screw 4 to make linear reciprocating motion. By controlling the speed of the motor 3, the stroke of the ball screw 4 can be adjusted, thereby driving the adjusting plate 1 to move left and right. When a large amount of flood discharge is required, all the flood discharge holes 2 on the adjusting plate 1 are opened. When a small amount of flood discharge is required, the water discharge holes 2 are partially opened to accurately control the water. When the water level drops to the safety threshold, the motor 3 reverses to reset the adjusting plate 1 and seal the flood outlet.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
