Description

Technical Field

[0001] The utility model relates to the technical field of emergency escape, in particular to an emergency escape device for a flooded factory building. Background Art

[0002] As a vital component of clean energy, hydropower plants are often constructed and operated in mountainous areas with complex geographical conditions and rugged terrain. These regions not only possess abundant hydropower resources, but also face the challenges of frequent natural disasters such as rainstorms and flash floods. These natural disasters, known for their suddenness and seasonality, create significant uncertainty for the stable operation of hydropower plants. In particular, under extreme weather conditions, hydropower station equipment is highly susceptible to failure, even leading to safety accidents.

[0003] Underground hydropower plants present particularly significant safety risks. Due to their unique location, underground plants are highly susceptible to flooding during heavy rains and flash floods. Such incidents not only severely damage the equipment within the plant but also pose a significant threat to personnel safety. In emergencies, in addition to routine maintenance and overhaul, ensuring the rapid and safe transfer of personnel and supplies becomes a pressing issue.

[0004] Currently, existing technical solutions for hydropower plant flooding accidents primarily focus on improving drainage measures, such as adding automatically opening drainage channels, using multi-stage pumps to enhance drainage capacity, or using buoyancy-driven switches to implement alarm functions for flooding accidents. However, while these existing technologies have improved hydropower plants' ability to respond to flooding accidents to a certain extent, they primarily focus on conventional measures such as drainage and alarms, and do not fully consider the urgent needs of relocating personnel and critical equipment and supplies. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides an emergency escape device for a flooded factory building. The escape device is embedded in a wall and connected to the wall via a driving member. A trigger member is installed on the wall. When the water rises and acts on the trigger member, the driving member drives the escape device to move out of the wall.

[0006] The escape device comprises:

[0007] The power unit, consisting of a motor and a battery, provides power to the transmission components;

[0008] A transmission component is connected to a power unit and is driven to move by the power unit;

[0009] A connecting member, the connecting member is fixed to the transmission component, the connecting member is driven to move periodically by the transmission component, and the connecting member is detachably connected to the bearing component;

[0010] The first floating switch is higher than the trigger member. When the water body rises and triggers the first floating switch, the power device drives the transmission member to move.

[0011] When a flood accident occurs, the water level in the factory building rises. When it rises to the height of the trigger member, the water acts on the trigger member. At this time, the driving member drives the escape device to move out of the wall so that the escape device is exposed on the wall surface. At this time, the first floating switch has not been touched and the escape device is not activated. The reason is that the water level is relatively shallow at this time. People can still quickly escape or quickly transfer equipment under this water level. Alternatively, the bearing component can be installed on the connecting member in advance. When the water level continues to rise to the height of the first floating switch, the water level is relatively deep, and it is difficult for people to move or they move slowly. The water acts on the first floating switch, the escape device is activated, and the power device drives the transmission component to move. People can hold the bearing component by hand, thereby providing power for the movement of people, helping people to move quickly under the impact of waves during the flooding accident. At the same time, it can also be used in conjunction with a cable to achieve rapid and safe transfer of important equipment.

[0012] Furthermore, the transmission component includes:

[0013] The rotating part is provided with two groups, and the two groups of rotating parts are arranged on the same vertical plane, and one group of the rotating parts is driven by a power device to rotate along its own circumferential direction;

[0014] The flexible restraining member is arranged around the two sets of rotating parts, and the flexible restraining member is driven to move by the rotating parts. The connecting member is fixed on the side of the flexible restraining member.

[0015] Furthermore, the transmission component formed by the cooperation between the rotating part and the flexible constraint member is selected from one of a chain and a sprocket, a chain and a chain plate, a cable and a winch, and a belt and a pulley.

[0016] Since the direction of the force applied to the transmission component is mainly vertical during the escape process, the rotating part is arranged vertically to prevent the flexible restraining member from being separated from the rotating part.

[0017] Furthermore, the escape device also includes a frame, which is connected to the above-mentioned driving member and connected to the wall through a guide member, and the power device and transmission components are installed in the frame.

[0018] By guiding the pop-up movement of the escape device through the guide piece, the friction between the escape device and the wall can be effectively reduced, thereby making the escape device easier to pop out.

[0019] Furthermore, the escape device also includes a controller for opening and closing control.

[0020] A separate battery is connected to the controller, which automatically charges the battery when it's low and stops charging when it's high. Even if a flooding accident causes a power plant circuit failure, the battery will not affect the emergency system's operation, ensuring it remains operational for a sufficient time.

[0021] Furthermore, the trigger is a floating restraint, which is mounted on the wall at a position corresponding to the lower front portion of the escape device. One end of the floating restraint is rotatably connected to the wall. The floating restraint contacts the front of the escape device and is driven to rotate around one end by the rising water.

[0022] The driving member is an elastic member.

[0023] Furthermore, a floating portion is provided at the end of the floating restraint.

[0024] When the water level rises, under the action of buoyancy, the water will drive the floating constraint to rotate around one end. When it rotates to a certain angle, the frame loses the constraint of the floating constraint. Under the action of the elastic member, the escape device pops out of the wall. A floating part with a larger contact surface with the water and a lighter mass is provided at the end of the floating constraint to increase the force of the water on the floating constraint.

[0025] Furthermore, the trigger selects the second floating switch;

[0026] The driving member is a power component.

[0027] When the water level rises, the water surface contacts the second float switch, generating a signal which is sent to the controller. The controller controls the power components to push the escape device to move, so that the escape device pops out of the wall.

[0028] The utility model has the following advantages:

[0029] When a flood accident occurs, the water level in the factory building rises. When it rises to the height of the trigger member, the water acts on the trigger member. At this time, the driving member drives the escape device to move out of the wall so that the escape device is exposed on the wall surface. At this time, the first floating switch has not been touched and the escape device is not activated. The reason is that the water level is relatively shallow at this time. People can still quickly escape or quickly transfer equipment under this water level. Alternatively, the bearing component is pre-installed on the connecting member. When the water level continues to rise to the height of the first floating switch, the water level is relatively deep, and people find it difficult to move or move slowly. The water acts on the first floating switch, the escape device is activated, and the power device drives the transmission component to move. People can hold the bearing component to provide power for people to move and transfer, thereby helping people to move quickly under the impact of waves during the flooding accident. At the same time, it can also be used in conjunction with a cable to achieve fast and safe transfer of important equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0046] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] As mentioned in the background, existing technical solutions for hydropower plant flooding accidents primarily focus on improving drainage measures. For example, these solutions include adding automatically opening drainage channels, using multi-stage pumps to enhance drainage capacity, or implementing buoyancy-driven switches to provide alarm functions for flooding accidents. However, while these existing technologies have improved hydropower plants' ability to respond to flooding accidents to a certain extent, they primarily focus on conventional measures such as drainage and alarms, and fail to fully consider the urgent needs of evacuating personnel and critical equipment and supplies.

[0048] Example 1:

[0049] Therefore, in order to solve the above technical problems existing in the prior art, this embodiment provides an emergency escape device for a flooded factory building, such as Figure 1 、 2 As shown, the escape device 200 is embedded in the wall 100 and is connected to the wall through a driving member 300. A trigger member 500 is installed on the wall. When the water rises and acts on the trigger member, the driving member drives the escape device to move out of the wall.

[0050] like Figure 3 、 4 As shown, the escape device includes:

[0051] The power unit 240 , consisting of a motor and a battery, provides power to the transmission components;

[0052] Transmission component 220, which is connected to the power device and is driven by the power device to move the transmission component;

[0053] A connecting member 270, which is fixed to the transmission component and drives the connecting member to move periodically via the transmission component. The connecting member is detachably connected to the bearing component;

[0054] The first floating switch 230 is higher than the trigger member. When the water rises and triggers the first floating switch, the power device drives the transmission member to move.

[0055] like Figure 9As shown, when a flooding accident occurs, the water level in the factory building rises. When it rises to the height of the trigger member, the water acts on the trigger member. At this time, the driving member drives the escape device to move out of the wall so that the escape device is exposed on the wall surface. At this time, the first floating switch has not been touched and the escape device is not activated. The reason is that the water level is relatively shallow at this time, and personnel can still quickly escape or quickly transfer equipment under this water level, or there is sufficient time to install the bearing component on the connecting member in advance. When the water level continues to rise to the height of the first floating switch, the water level is relatively deep, and it is difficult for personnel to move or move slowly. The water acts on the first floating switch, the escape device is activated, and the power device drives the transmission component to move. Personnel can hold the bearing component by hand to provide power for personnel movement and transfer, thereby assisting personnel to move quickly under the wave impact conditions during the flooding accident. At the same time, it can also be used in conjunction with cables to achieve rapid and safe transfer of important equipment.

[0056] It should be noted that the movement of the escape device out of the wall does not mean that the entire escape device has left the cavity, but that part of it is exposed. Figure 9 As shown, the escape device is ejected from the wall by the driving member, partially emerging from the wall. This partially emerging refers to the portion of the escape device where the transmission components are mounted, specifically the portion where the transmission components are located. This provides sufficient support for personnel escape or equipment transfer, preventing the escape device from becoming loose.

[0057] In this embodiment, the power device includes but is not limited to a servo motor, a stepper motor, etc. The load-bearing components include but are not limited to hooks, handrails, and other components that can bear the weight of people or equipment.

[0058] In this embodiment, the connecting member may be Figure 7 The annular structure shown can be designed with a hook or hook-type end for connecting the load-bearing component to the connector, allowing for quick connection between the load-bearing component and the connector. Of course, the connector can also be of other structures, such as a screw (in which case the connecting portion between the load-bearing component and the connector should be a matching threaded sleeve).

[0059] In this embodiment, if Figure 7 As shown, the transmission component includes:

[0060] The rotating part 222 is provided with two groups, and the two groups of rotating parts are arranged on the same vertical plane, and one group of the rotating parts is driven by a power device to rotate along its own circumferential direction;

[0061] The flexible restraining member 221 is arranged around the two sets of rotating parts, and the flexible restraining member is driven to move by the rotating parts. The connecting member is fixed on the side of the flexible restraining member.

[0062] The transmission component formed by the cooperation between the rotating part and the flexible constraint member is selected from one of a chain and a sprocket, a chain and a chain plate, a cable and a winch, and a belt and a pulley.

[0063] Since the direction of the force applied to the transmission component is mainly vertical during the escape process, the rotating part is arranged vertically to prevent the flexible restraining member from being separated from the rotating part.

[0064] In addition, in this embodiment, the escape device further includes a frame 210, such as Figure 1 As shown, the frame is connected to the aforementioned drive member and to the wall via a guide member 400. The power device and transmission components are mounted within the frame 210. The frame provides installation space and protection for other components of the escape device. The guide member guides the ejection movement of the escape device, effectively reducing friction between the escape device and the wall, making it easier to eject.

[0065] In this embodiment, the guide member may be a structure of a slider and a guide rail, or a structure of a pulley and a guide groove, or a structure of a slider and a guide rod, etc.

[0066] like Figure 6 As shown, the escape device further includes a controller 260 for opening and closing control.

[0067] The power source may be a battery or other power supply device with energy storage and discharge functions.

[0068] A separate battery is connected to the controller and automatically charges when the battery level is low and stops charging when the battery level is high. This ensures that even if the power plant circuit fails during a flooding accident, the emergency system will not be affected, as the battery ensures sufficient operating time.

[0069] It should be noted that the power device, power supply, and controller should be installed at a position higher than the transmission components, such as the top of the frame, so that the power device, power supply, and controller are not easily submerged in water and damaged, or a sealed and waterproof installation box or cavity should be set to provide installation space for the power device, power supply, and controller, and the water should be isolated by the sealed and waterproof installation box or cavity to prevent water from entering the installation box or cavity and causing damage to the power device, power supply, and controller.

[0070] Example 2:

[0071] This embodiment provides a trigger and a driving member structure, such as Figure 1 、 2As shown, the trigger is a floating restraint, which is mounted on the wall at a position corresponding to the lower front portion of the escape device. One end of the floating restraint is rotatably connected to the wall. The floating restraint contacts the front of the escape device and is driven to rotate around one end by the rising water.

[0072] The driving member is an elastic member.

[0073] A floating portion is also provided at the end of the floating restraint.

[0074] In this embodiment, the floating restraint may be a floating pin, a floating rod, or the like; the floating portion may be a floating plate, a floating block, a floating ball, or the like with a large contact surface with the water and a relatively light weight; and the elastic member may be a spring, an elastic band, an elastic cord, or other component that can be reset after being stretched or compressed.

[0075] like Figure 2 As shown, when the escape device is entirely contained within the wall, the frame of the escape device compresses or pulls up the elastic member, and the floating restraint member restrains the escape device to prevent the escape device from being ejected from the wall under the action of the elastic force. When the water level rises, under the action of buoyancy, the water body drives the floating restraint member to rotate around one end thereof. When it rotates to a certain angle, the frame loses the restraint of the floating restraint member, and under the action of the elastic member, the escape device is ejected from the wall. A floating portion with a larger contact surface with the water body and a lighter mass is provided at the end of the floating restraint member to increase the force of the water body on the floating restraint member.

[0076] Example 3:

[0077] This embodiment provides another structure of the trigger and the driving member, such as Figure 8 As shown, the trigger selects the second float switch;

[0078] The driving member is a power component.

[0079] In this embodiment, the power components include but are not limited to cylinders, hydraulic cylinders or other components that can drive the escape device to move linearly.

[0080] When the water level rises, the water surface contacts the second float switch, generating a signal which is sent to the controller. The controller controls the power components to push the escape device to move, so that the escape device pops out of the wall.

[0081] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
