Detailed implementation mode

[0045] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in combination with embodiments and the accompanying drawings. The illustrative embodiments of the present application and their descriptions are only used to explain the present application and are not intended to limit the present application.

[0046] It can be referred to together Figures 1 to 11 , an in-river landscape rescue device is provided in an embodiment of the present application. The in-river landscape rescue device includes an equipment well 2, a telescopic column 7, a pedal 6, a safety rope 8 and a controller; the equipment well 2 is a groove-shaped member with a certain opening, and the equipment well 2 is used to be buried below the river beach ground to prevent the equipment well 2 from affecting the ecological landscape. Among them, the equipment well 2 has an end cover 1 that can be controlled to open. When the equipment well 2 is pre-buried, the end cover 1 is flush with the river beach ground, and decorations can be added to the end cover 1 to achieve its ecological integration with the river beach; the telescopic column 7 is located in the equipment well 2, and the length direction of the telescopic column 7 coincides with the groove depth direction of the equipment well 2. When the telescopic column 7 is controlled to act, its free end can reach above the river beach ground through the wellhead of the equipment well 2, that is, after the end cover 1 is controlled to open, the telescopic column 7 is controlled to extend, and its free end can reach above the river beach ground through the wellhead of the equipment well 2. As the telescopic column 7 continues to extend, the free end of the telescopic column 7 has an increasing height; a plurality of pedals 6 are arranged at intervals along the length direction of the telescopic column 7 and are respectively connected to the telescopic column 7. The plurality of pedals 6 can be used for the rescued person to climb to a higher position to prevent drowning; the safety rope 8 is connected to the telescopic column 7; the controller is electrically connected to the telescopic column 7 and the end cover 1.

[0047] During use, when the controller receives a flood signal, the controller controls the end cover 1 to open, and then controls the telescopic column 7 to extend so that the free end of the telescopic column 7 is at a high position. The trapped person can climb through the pedal 6 on the telescopic column 7 to reach a higher position and obtain additional safety protection through the safety rope 8, and then wait for rescue; after the controller receives a signal that the flood has receded, the controller controls the telescopic column 7 to contract. After the telescopic column 7 contracts in place and is completely located in the equipment well 2, the controller controls the end cover 1 to close.

[0048] In an embodiment of the present application, for electrically controlled components such as the end cover 1 and the telescopic column 7, the circuits inside them can all be waterproofed to avoid the device being scrapped after contacting water.

[0049] The river landscape rescue device provided in the embodiment of the present application can achieve rapid response and efficient rescue by integrating the equipment well 2, telescopic columns 7, pedals 6, safety ropes 8 and controller; the equipment well 2 is buried below the river beach ground, and its end cover 1 can be opened in a controlled manner to ensure that the device does not affect the river landscape when not in use. When a flood or emergency occurs, the controller activates the telescopic column 7 to extend its free end from the equipment well 2 to above the river beach ground, and multiple pedals 6 form a stepped rescue channel. The safety rope 8 is connected to the telescopic column 7 to provide additional safety protection for rescuers or trapped persons; the device can be quickly deployed , adapting to the rescue needs in extreme weather or upstream dam burst situations, and solving the problem that traditional rescue methods may have delayed response and untimely rescue, resulting in the risk of drowning for trapped persons. That is, trapped persons can use the device to save themselves in time, so that they are in a high place and do not drown, and at the same time provide more buffer time for rescuers; in addition, the device is hidden below the ground, which neither affects the ecological environment of the river nor occupies ground space, effectively alleviating the contradiction between ecology and engineering; through intelligent control, the device realizes the automation and efficiency of the rescue process, and significantly improves the rescue coordination capability and safety.

[0050] In some optional embodiments, the telescopic column 7 includes a first telescopic joint, a second telescopic joint and a telescopic driving source; the first telescopic joint is connected to the equipment well 2, and the first telescopic joint is a cylindrical member with a certain length, wherein the cross-sectional shape of the first telescopic joint is a rectangle; the second telescopic joint is movably arranged in the first telescopic joint, and the second telescopic joint can also be designed as a cylindrical member with a certain length, and the cross-sectional shape of the second telescopic joint is a rectangle adapted to the first telescopic joint; the telescopic driving source is transmission-connected to the second telescopic member to drive the second telescopic member to move along the length direction of the first telescopic member; wherein, the pedal 6 is connected to the second telescopic member, and when the second telescopic joint is retracted into the first telescopic joint, the pedal 6 is located between the first telescopic joint and the second telescopic joint.

[0051] In the embodiment of the present application, the driving mode of the telescopic drive source for the second telescopic section includes but is not limited to magnetic drive, hydraulic drive, mechanical transmission drive, etc., wherein the mechanical transmission drive includes but is not limited to transmission through a screw and nut mechanism, transmission through a pulley set, transmission through a worm gear mechanism, transmission through a rack and pinion, etc.; that is, the transmission connection in the embodiment of the present application is an assembly method or connection method in which one component can transmit driving force to another component.

[0052] As mentioned above, when the second telescopic section retracts into the first telescopic section, the pedal 6 is located between the first telescopic section and the second telescopic section. If the pedal 6 is fixedly connected to the second telescopic section, the pedal 6 will always be in a state where the plate surface coincides with the horizontal plane. This will require a relatively large spacing to be designed between the first telescopic section and the second telescopic section, thereby increasing the space occupation. To reduce the overall space occupation of the device, in some alternative embodiments, the pedal 6 is rotatably connected to the second telescopic section. The pedal 6 is configured with a rotational drive source to rotate under the drive of the rotational drive source. The rotational drive source is electrically connected to the controller. When the second telescopic section retracts into the first telescopic section, the controller controls the rotational drive source to operate so that the pedal 6 rotates to a state where the plate surface is parallel to the vertical direction. At this time, the space occupation of the pedal 6 between the first telescopic section and the second telescopic section is relatively small. When the second telescopic section extends out of the first telescopic section, the controller controls the rotational drive source to operate so that the pedal 6 rotates to a state where the plate surface is parallel to the horizontal plane. At this time, the pedal 6 is suitable for trapped persons to climb. Among them, strip-shaped through holes can be provided on the pedal 6 for the trapped persons to hold with their hands.

[0053] To further reduce the space occupation of the pedal 6 between the first telescopic section and the second telescopic section, in some alternative embodiments, a relief groove adapted to accommodate the pedal 6 is provided on the second telescopic section, that is, when the second telescopic section retracts into the first telescopic section, the pedal 6 is located in the relief groove, and the plate surface of the pedal 6 coincides with or is lower than the side surface of the second telescopic section. To avoid water accumulation in the relief groove, the plate surface of the pedal 6 coincides with the side surface of the second telescopic section. Among them, a sealing layer can also be provided on the groove wall of the relief groove to prevent a large gap from being formed when the pedal 6 rotates into the relief groove.

[0054] In some alternative embodiments, the second telescopic section includes a plurality of sub-telescopic sections with sequentially decreasing sizes. The sub-telescopic section with a smaller size is inserted into the sub-telescopic section with a larger size. Among them, the pedal 6 is respectively connected to each sub-telescopic section, so that the plurality of sub-telescopic sections can also be telescoped. The plurality of sub-telescopic sections and the first telescopic section substantially form a multi-stage telescopic mechanism. In this way, when the telescopic column 7 is fully extended, the sub-telescopic section with the smallest size can obtain a higher height to be applicable to occasions with a higher water level.

[0055] Since this application needs to be buried below the river beach ground, the soil quality of the river beach ground is generally not stable enough. If the overall volume of the device is large, the disturbance to the soil during the installation process will be greater, which will be disadvantageous to maintaining the stability of the device in the environment below the river beach ground. Therefore, in some alternative embodiments, each sub-expansion joint is preferably driven hydraulically. Specifically, the first expansion joint is an overall rectangular cylinder structure. An assembly groove is opened from one end face of the first expansion joint to the other end. A piston is arranged in the assembly groove. The assembly groove is sealed by a sealing cover. The sub-expansion joint is also a rectangular cylinder structure. An assembly rod is arranged on the outer side wall of the sub-expansion joint. The length direction of the assembly rod is parallel to the length direction of the sub-expansion joint and there is a spacing between the assembly rod and the outer side wall of the sub-expansion joint. One end of the assembly rod passes through the sealing cover and is connected to the piston. The assembly groove serves as a piston cylinder, and the assembly rod serves as a piston rod. The assembly rod and the assembly groove together form a piston structure. The sub-expansion joint also opens an assembly groove from one end face to the other end to cooperate with a smaller sub-expansion joint; wherein, a hydraulic hole is arranged at the bottom of the assembly groove in the first expansion joint and the sub-expansion joint for fluid to enter the assembly groove. Since the position of the sub-expansion joint is uncertain, the hydraulic hole on the sub-expansion joint can be connected to a hydraulic machine 12 through a flexible hose. Compared with a conventional mechanical transmission mechanism for driving, the number of components is less by means of hydraulic transmission. On the one hand, the space occupation is controlled, and on the other hand, the manufacturing cost can be reduced; compared with magnetic drive, the increase in space occupation is not large, and the manufacturing cost is lower.

[0056] In some alternative embodiments, the telescopic column 7 is rotatably connected to the bottom of the equipment well 2. The telescopic column 7 is driven to rotate by a rotation drive source 5. Among them, a first fastener 3 is arranged on the telescopic column 7, and a second fastener 4 is arranged on the well wall of the equipment well 2. When the first fastener 3 rotates with the telescopic column 7, it can form a buckle with the second fastener 4.

[0057] In the embodiment of this application, when the telescopic column 7 rotates, the first fastener 3 can form a buckle with the second fastener 4, thereby fixing the position of the telescopic column 7. This design enables the device to remain stable after being deployed, avoiding the device from shaking or tilting due to water flow impact or other external forces, and ensuring the safety and reliability of the rescue passage; the design of the rotational connection also enables the telescopic column 7 to flexibly adjust the angle when being stored, facilitating the compact storage of the device in the equipment well 2, reducing the occupation of ground space. At the same time, the buckling structure further enhances the stability and anti-impact ability of the device. Especially under high water flow or complex terrain conditions, it can effectively prevent the device from accidentally moving or tipping over.

[0058] In specific implementation, the first fastener 3 is an L-shaped rod. The number of the first fasteners 3 can be set to four and evenly distributed around the circumference of the telescopic column 7. An L-shaped groove adapted to cooperate with the L-shaped rod is formed on the second fastener 4. The second fastener 4 is a cuboid as a whole, and the number of the second fasteners 4 is also four and arranged in a circular pattern. Thus, when the telescopic column 7 rotates, the positions of the first fastener 3 and the second fastener 4 can correspond one by one, and the end of the L-shaped rod is inserted into the L-shaped groove on the second fastener 4.

[0059] In some alternative embodiments, a plurality of drain holes 9 are formed at the bottom of the equipment well 2. The arrangement of the drain holes 9 can reduce the accumulated water in the equipment well 2 and avoid excessive corrosion of the device caused by excessive accumulated water. Among them, the rotation of the first fastener 3 can form a synergistic effect with the drain holes 9. Specifically, when the telescopic column 7 retracts into the equipment well 2, the stability requirement of the telescopic column 7 is reduced. At this time, the telescopic column 7 is driven to rotate by the rotation drive source 5. The four first fasteners 3 on the telescopic column 7 can rotate synchronously and block the drain holes 9, which means that the first fastener 3 and the drain holes 9 form a separable sealing structure. This can prevent water from seeping into the equipment well 2 through the drain holes 9 to a certain extent when the device is not in use. When the telescopic column 7 extends out, flood water will enter the equipment well 2 through the wellhead of the equipment well 2. The first fastener 3 rotates synchronously with the telescopic column 7, and the first fastener 3 disengages from the drain holes 9. After the device is used up, the water in the equipment well 2 can be discharged from the drain holes 9, avoiding excessive accumulated water in the equipment well 2.

[0060] In some alternative embodiments, the end cover 1 includes a first sub-cover and a second sub-cover. The first sub-cover and the second sub-cover are joined together to form the end cover 1. The first sub-cover and the second sub-cover can be respectively connected to the wellhead of the equipment well 2 through mechanical transmission members such as a lead screw nut mechanism. The lead screw nut mechanism is provided with a motor, and the motor is connected to the controller. Thus, by controlling the motor to work by the controller, the first sub-cover and the second sub-cover can be made to approach or separate from each other, and further the opening and closing of the end cover 1 can be realized. In other embodiments, the first sub-cover and the second sub-cover can also be moved on the equipment well 2 through hydraulic transmission, magnetic drive, pneumatic drive, etc.

[0061] In some alternative embodiments, the in-river landscape rescue device further includes a water pressure sensor 10, a voice broadcaster 11 and a camera assembly 13. The water pressure sensor 10 is connected to the equipment well 2 and buried below the river beach ground. By detecting the water pressure, the controller can determine whether the water volume on the river beach is at a normal value. The voice broadcaster 11 is connected to one end of the second telescopic section. The camera assembly 13 is used to be arranged on the river beach bank. Among them, the water pressure sensor 10, the voice broadcaster 11 and the camera assembly 13 are respectively electrically connected to the controller.

[0062] In the embodiments of the present application, the telescopic column 7 can be photographed by the camera assembly 13. The controller identifies humans through the photographed images to determine whether there are trapped persons on the telescopic column 7. If the determination is yes, the controller controls the voice broadcaster 11 to work to emit a rescue signal to attract the attention of rescue personnel. If the determination is no, the voice broadcaster 11 does not work.
