Abstract
Description
Technical Field
[0001] This invention relates to the field of earthquake-resistant building technology, and more specifically, to an isolation wall structure for a water plant area and its construction method. Background Technology
[0002] Insulation walls are common building envelopes in municipal, industrial, and infrastructure projects, primarily used for space separation, security protection, noise blocking, or landscape isolation. Traditional insulation walls are mostly constructed of brick, cast-in-place concrete, or precast concrete slabs, directly anchored to the ground via rigid foundations, relying on the wall's own strength and rigidity to resist external loads. While these structures perform well under static or wind loads, under seismic activity, the lack of energy dissipation or displacement release mechanisms between the wall and foundation means that almost all seismic forces are transferred to the wall, leading to cracking, misalignment, or even collapse, ultimately resulting in the loss of their enclosure function.
[0003] Within the water treatment plant area, the isolation wall not only separates the production area, office area, and municipal access, but also plays a crucial role in protecting the continuous operation of the water purification process: it surrounds the chemical dosing room, filter tanks, pump room, and power distribution room, preventing unauthorized entry by external vehicles and personnel, while also blocking the spread of windblown sand, noise, and chemical odors. If the isolation wall is damaged during an earthquake, the collapsed wall may destroy equipment, tear pipelines, causing production shutdowns, chemical leaks, and secondary pollution. Therefore, the water treatment plant's isolation wall must possess strong seismic isolation and earthquake resistance capabilities.
[0004] Existing seismic isolation walls generally employ rigid foundation connections or simple rubber pads for seismic isolation. However, rigid connections allow seismic forces to be directly transmitted, causing the wall to withstand high shear forces and bending moments during earthquakes, making it highly susceptible to cracking. While traditional rubber seismic isolation bearings can extend the seismic period, their effectiveness in isolating long-period ground motions is poor, and rubber is prone to aging and has limited load-bearing capacity. Therefore, existing seismic isolation walls suffer from poor seismic resistance and isolation performance. Summary of the Invention
[0005] The purpose of this invention is to provide an isolation wall structure for a water plant area, which can improve the wall's seismic resistance and isolation capabilities and reduce earthquake damage to the wall.
[0006] In a first aspect, embodiments of the present invention are achieved through the following technical solution: a partition wall structure for a water plant area, comprising: a wall upper beam, a wall base, and a wall panel, wherein the wall panel is disposed between the wall upper beam and the wall base, the wall upper beam and the wall panel are rotatably connected, a gap is reserved between the bottom end of the wall panel and the wall base for the wall panel to swing, the bottom end of the wall panel swings relative to the wall upper beam during an earthquake, a power gear is rotatably disposed at the bottom end of the wall panel, and an arc-shaped rack is disposed on the top surface of the wall base along the swing direction of the wall panel. The gear meshes with the arc rack. An acceleration component and a dual gyroscope rotor assembly are provided inside the wall panel. The rotation shaft of the power gear is connected to the input shaft of the acceleration component, and the input shaft of the dual gyroscope rotor assembly is connected to the output shaft of the acceleration component. The dual gyroscope rotor assembly includes a central drive shaft and two opposing gyroscope disks. One end of the central drive shaft is connected to the output shaft of the acceleration component. The central drive shaft drives the two gyroscope disks to rotate in opposite directions through a bevel gear or idler gear, which is used to convert the oscillating kinetic energy of the wall panel into the rotational kinetic energy of the gyroscope disks.
[0007] Furthermore, the acceleration component includes a large bevel gear and a small bevel gear. The power gear drives the large bevel gear to rotate through a transmission component. The small bevel gear meshes with the large bevel gear. The gear ratio between the large bevel gear and the small bevel gear is greater than 1. The rotation axis of the small bevel gear is the output axis of the acceleration component.
[0008] Furthermore, a cam and a scroll spring are provided at the end of the output shaft of the acceleration component away from the end connected to the dual gyroscope rotor assembly. The inner end of the scroll spring is fixed to the rotation axis of the cam, and a rolling bearing is provided at the outer end of the scroll spring. The rolling bearing is always pressed against the outer contour surface of the cam.
[0009] Furthermore, the profile of the cam is a cubic-tangent composite curve, or an equivalent non-circular curve that can achieve nonlinear stiffness variation with swing angle.
[0010] Furthermore, a worm is provided at the end of the output shaft of the acceleration component away from the end connected to the dual gyroscope rotor assembly, and a worm wheel is rotatably provided inside the wall plate. The worm wheel meshes with the worm, and a reset torsion spring is wound around the rotation shaft of the worm wheel. The rotating worm wheel coils the reset torsion spring.
[0011] Furthermore, the lead angle of the worm is greater than the equivalent friction angle of the worm, and the torque of the reset torsion spring is much greater than the static friction torque of the worm.
[0012] Furthermore, a one-way bearing is provided between the output shaft of the acceleration component and the central drive shaft to limit the power to be transmitted unidirectionally from the acceleration component to the dual gyroscope rotor assembly.
[0013] Furthermore, a centrifugal pawl and ratchet assembly is provided on the central drive shaft. The centrifugal pawl and ratchet assembly is used to brake the rotation of the central drive shaft when the rotation speed of the gyroscope exceeds a preset threshold, thereby forcing the gyroscope to stop rotating.
[0014] Furthermore, a ball head is provided with a protrusion at the bottom center of the wall panel, and a ball socket is provided on the top surface of the wall base. The ball head is slidably disposed in the ball socket, and the ball head abuts against the inner wall of the ball socket. The spherical radius of the ball head is smaller than the opening radius of the ball socket.
[0015] Secondly, this invention discloses a construction method for an isolation wall structure in a water plant area, comprising: S1. Connect the dual gyroscope rotor assembly, cam, worm gear and the output shaft of the acceleration assembly respectively; S2. Install the dual gyro rotor assembly, cam, worm gear and acceleration assembly into the space reserved in the wall panel, connect the input end of the acceleration assembly to the power gear, and mesh the power gear at the lower end of the swing arm with the arc rack. S3. Hoist the wall panel as a whole between the upper beam of the wall and the base of the wall. The top of the wall panel is rotatably connected to the upper beam of the wall, and the ball head at the bottom of the wall panel is aligned with the ball socket.
[0016] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects: 1. This invention uses a rotating connection between the upper beam and the wall panel of the wall structure, with a pre-reserved swing gap at the bottom of the wall panel. During an earthquake, the wall panel can swing relative to each other, avoiding the direct transmission of seismic force under rigid connection, reducing shear force and bending moment in the wall. The power gear at the bottom of the wall panel meshes with the arc rack of the wall base, converting the swing into gear rotation. The gear rotation is transmitted to the dual gyroscope rotor assembly through the acceleration component, driving the two gyroscope disks to rotate in opposite directions, realizing the conversion of swing kinetic energy into gyroscope disk rotation kinetic energy. The rotation of the gyroscope disks generates a counter-torque opposite to the seismic force, offsetting the seismic effect, suppressing the wall panel swing, improving the seismic isolation and earthquake resistance effect, and avoiding secondary problems caused by damage to the water plant isolation wall. 2. This invention utilizes a combination of a cam and a spiral spring to achieve nonlinear stiffness adjustment based on the magnitude of the earthquake swing angle. The cam's profile is designed as a cubic-tangent composite curve, which maintains low stiffness and extends the period during minor earthquakes to avoid resonance, while rapidly increasing stiffness during major earthquakes to limit displacement and prevent structural damage. This adaptive nonlinear energy dissipation characteristic enables the wall structure to adapt to earthquakes of different intensities, improving the structure's seismic toughness and reliability. 3. This invention provides a purely mechanical reset method that requires no external power source by combining a worm gear and a return torsion spring. After an earthquake, the return torsion spring drives the worm in the opposite direction through the worm gear, thereby restoring the wall panel to its initial state. Attached Figure Description

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.
[0022] The following description, in conjunction with specific embodiments, provides further details. Example
[0023] Reference Figures 1-9 As shown, this invention relates to an isolation wall structure for a water plant area. (Refer to...) Figure 1 and Figure 2 The system includes a wall beam 100, a wall base 200, and a wall panel 300. The wall beam 100 and the wall base 200 are integrally connected to the building foundation and are arranged opposite each other in the vertical direction. The wall panel 300 is installed between the wall beam 100 and the wall base 200. Multiple universal joints 101 are installed between the wall beam 100 and the wall panel 300. The outer ring 102 of the universal joint 101 is fixedly installed on the bottom surface of the wall beam 100, and the inner ring 103 of the universal joint 101 is fixedly connected to the top of the wall panel 300.
[0024] Reference Figure 2 and Figure 3A ball joint 301 is protruding from the bottom of the wall panel 300, with its centerline coinciding with the vertical line of the wall panel 300's center of gravity. A ball socket 201 is formed on the top surface of the wall base 200, and the ball joint 301 slides against the ball socket 201, forming a ball hinge. The ball joint 301 and the ball socket 201 cooperate to support the weight of the wall panel 300. The opening radius of the ball socket 201 is at least twice the spherical radius of the ball joint 301 to ensure that the ball joint 301 swings freely within the ball socket 201. When no earthquake occurs, the wall panel 300 is in a vertical position, with the ball joint 301 located at the center of the ball socket 201, transferring the weight of the wall panel 300 to the wall base 200 through the ball joint 301 and the ball socket 201. When an earthquake occurs, the wall panel 300 swings around the universal joint 101, the ball head 301 moves within the ball socket 201, and the maximum swing angle of the wall panel 300 is limited to 6°.
[0025] Reference Figure 2 and Figure 3 A gap is provided between the wall panel 300 and the upper beam 100 and the wall base 200 to allow the wall panel 300 to swing. Sealing strips 202 are installed on the bottom surface of the upper beam 100 and the top surface of the wall base 200, respectively. The sealing strips 202 are used to seal the edge gaps between the wall panel 300 and the upper beam 100 and the wall base 200. Simultaneously, when the wall panel 300 swings, it compresses the sealing strips 202 to prevent foreign objects from entering. An arc-shaped toothed strip 203 is also installed on the top surface of the wall base 200, and the arc-shaped toothed strip 203 is recessed into the top surface of the wall base 200.
[0026] Reference Figure 4 and Figure 5 Multiple sets of energy dissipation and reset devices are installed inside the wall panel 300. These devices are equidistantly distributed along the width of the wall panel 300 to dissipate energy during an earthquake and restore the displaced wall panel 300 to its original position. Specifically, the wall panel 300 has an internal cavity for housing the energy dissipation and reset devices. A housing 302 is installed within this cavity to enclose the internal structure of the energy dissipation and reset devices. A swing arm 303 protrudes from the bottom of the wall panel 300, and a power gear 304 is rotatably mounted at the bottom end of the swing arm 303. A first transmission bevel gear 305 is fixedly mounted on the output shaft of the power gear 304, and the power gear 304 and the first transmission bevel gear 305 are coaxially connected. An arc rack 203 is arranged along the swing direction of the wall panel 300. When the wall panel 300 swings, the power gear 304 engages and rolls along the arc rack 203.
[0027] Reference Figure 4 and Figure 6A through hole is provided at the bottom of the wall panel 300, connecting the receiving cavity of the wall panel 300 to the bottom surface. A transmission rod 306 is rotatably mounted inside the wall panel 300, extending along the height direction of the wall panel 300. The bottom end of the transmission rod 306 passes through the through hole and is connected to a second transmission bevel gear 307, which meshes with a first transmission bevel gear 305. An acceleration assembly 310 is connected to the top end of the transmission rod 306, comprising a large bevel gear 311 and a small bevel gear 312. The rotation axis of the large bevel gear 311 coincides with and is fixedly connected to the axis of the transmission rod 306. The small bevel gear 312 meshes with the large bevel gear 311, and the gear ratio between the large bevel gear 311 and the small bevel gear 312 is greater than 1. The second transmission bevel gear 307 drives the large bevel gear 311 to rotate synchronously, and the rotation axis of the small bevel gear 312 is the output shaft of the acceleration assembly 310. The low-frequency oscillations of the earthquake are amplified and transformed into high-speed rotation of the output shaft of the acceleration component 310, which then serves as the power source for subsequent mechanisms.
[0028] Reference Figure 7 The wall panel 300 also houses a dual-gyro rotor assembly 320, which includes a central drive shaft 321 and two opposing gyro disks 322. One end of the central drive shaft 321 is connected to the output shaft of the acceleration assembly 310, and a one-way bearing 323 is installed between the central drive shaft 321 and the output shaft of the acceleration assembly 310 to limit power transmission only unidirectionally from the acceleration assembly 310 to the dual-gyro rotor assembly, preventing reverse transmission. The two gyro disks 322 are arranged opposite each other, and their rotation axes are on the same straight line. In this embodiment, the two gyro disks 322 are driven to rotate in opposite directions via a bevel gear set on the central drive shaft 321. The dual-gyro rotor assembly 320 is used to instantaneously convert the low-frequency, large-displacement mechanical energy input from an earthquake into high-speed rotating angular kinetic energy, which is then gradually dissipated through bearing friction, air resistance, and a subsequent reset mechanism, achieving efficient energy consumption. During an earthquake, as the wall panel 300 swings, the acceleration component 310 converts the kinetic energy of the wall panel 300 into the rotational inertial kinetic energy of the gyroscope disk 322, storing the energy. The rotation of the gyroscope disk 322 generates a counter-torque (the cross product direction is opposite to the seismic force), and the magnitude of the counter-torque is proportional to the square of the seismic acceleration, thus amplifying the inertia.
[0029] Specifically, the energy conversion process in the dual gyroscope rotor assembly 320 is as follows: Angular kinetic energy amplification stage. During an earthquake, the swing angle of the wall panel 300 is accelerated by the acceleration assembly 310, resulting in angular velocity amplification transmitted to the two gyroscope disks 322. The angular kinetic energy of the gyroscope disks 322 is proportional to the square of the earthquake acceleration, achieving quadratic amplification.
[0030] Reference Figure 7A centrifugal pawl and ratchet assembly 314 is mounted on the central drive shaft 321. The centrifugal pawl and ratchet assembly 314 includes a centrifugal pawl mounted on the central drive shaft 321 and a ratchet disposed around the central drive shaft 321. The outer shell of the centrifugal pawl and ratchet assembly 314 is fixedly connected to the housing 302, and the ratchet is fixedly mounted on the inner wall of the housing. When the rotational speed of the central drive shaft 321 is less than a preset speed threshold, the rotational speed of the gyroscope disk 322 does not exceed the preset threshold. The centrifugal pawl is pressed tightly against the central drive shaft 321 under the action of a spring, allowing the central drive shaft 321 to rotate freely. When the rotational speed of the central drive shaft 321 exceeds the preset speed threshold, the rotational speed of the gyroscope disk 322 exceeds the preset threshold. In this embodiment, the preset speed threshold is 4200 rpm (i.e., seismic acceleration ≥ 0.4g). The centrifugal pawl overcomes the spring preload, causing the centrifugal block in the centrifugal pawl ratchet assembly 314 to fly outwards, making the centrifugal pawl engage with the ratchet. This causes the central drive shaft 321 to stop rotating instantly, and the angular momentum of the gyroscope disk 322 to drop sharply, locking the wall panel 300 from a "flexible oscillation" to a "rigid body," preventing excessive displacement of the wall panel 300 and protecting the equipment. The centrifugal pawl ratchet assembly 314 in this embodiment has a conventional structure, therefore the internal structure diagram of the centrifugal pawl ratchet assembly 314 is not shown in the instruction manual. When the centrifugal pawl ratchet assembly 314 actuates, it enters the instantaneous energy locking stage. The gyroscope disk 322 has a large mass and high rotation speed, and its angular momentum L=I_gω is very large. It cannot be consumed by external disturbances in a short time, locking the seismic energy in rotational inertia and avoiding direct impact on the wall panel 300. Then, the system enters the energy dissipation stage. The angular kinetic energy is converted into heat energy and dissipated by the bearing friction heat generated by the high-speed rotation of the gyroscope disk 322, air resistance, and subsequent friction dissipation processes.
[0031] Reference Figure 8 The wall panel 300 also houses a cam 330 and a spiral spring 331. The rotation shaft of the cam 330 is fixedly connected to the end of the output shaft of the acceleration assembly 310 away from the central drive shaft 321. When the output shaft of the acceleration assembly 310 rotates, it drives the cam 330 to rotate. The profile of the cam 330 is a cubic-tangent composite curve, or an equivalent non-circular curve that can achieve nonlinear stiffness variation with the swing angle. The inner end of the spiral spring 331 is fixedly connected to the rotation shaft of the cam 330, and a rolling bearing 332 is rotatably mounted on the outer end (free end) of the spiral spring 331 via a connecting rod. The rolling bearing 332 always rolls along the outer contour surface of the cam 330. During an earthquake, the wall panel 300 swings, the cam 330 rotates, and the profile of the cam 330 pushes the rolling bearing 332 to compress the outer end of the spiral spring 331. The spiral spring 331 coils up one turn at a time, storing and absorbing earthquake energy.
[0032] When the swing angle is within the range of 0-3°, the rolling bearing 332 is in the base arc segment, and the outer end of the spiral spring 331 is not compressed, which is a low-stiffness region. The stiffness of the spiral spring 331 remains almost unchanged or increases slowly. When the seismic intensity is low, the spiral spring 331 maintains low stiffness, lengthening the natural vibration period of the wall panel 300, avoiding the dominant period of the earthquake, reducing resonance amplification, and minimizing the force transmitted to the building foundation.
[0033] When the swing angle is within the range of 3-6°, the stiffness of the spiral spring 331 suddenly increases, and the system exhibits a "mechanical limiting" effect, entering an instantaneous energy locking stage. This prevents the wall panel 300 from displacing excessively, and the remaining energy continues to dissipate through bearing friction and air resistance. At higher earthquake intensities, the stiffness of the spiral spring 331 increases dramatically, generating a strong restoring torque that limits the further expansion of the wall panel 300's displacement, preventing collapse or excessive deformation and protecting internal equipment and pipelines.
[0034] Reference Figure 9 A worm gear 340 is fixedly installed at the end of the output shaft of the acceleration component 310 away from the central drive shaft 321. The worm gear 340 rotates synchronously with the output shaft of the acceleration component 310. A worm wheel 341 is rotatably installed inside the wall panel 300, and the worm wheel 341 meshes with the worm gear 340. A return torsion spring 342 is also installed on the rotating shaft of the worm wheel 341, and the return torsion spring 342 is wound around the rotating shaft of the worm wheel 341. During the rotation of the worm wheel 341, the return torsion spring 342 is wound tightly, and the return torsion spring 342 further absorbs and stores seismic energy. In this embodiment, the lead angle of the worm gear 340 is greater than the equivalent friction angle of the worm gear 340.
[0035] During an earthquake, the worm gear 340 rotates at a certain speed, and there is dynamic friction between the worm gear 340 and the worm wheel 341. The worm gear 340 drives the worm wheel 341 to successfully coil the return spring. A small portion of the energy is consumed by air resistance and the meshing friction between the worm gear 340 and the worm wheel 341, but the majority is stored in the return spring.
[0036] During the earthquake-induced reset phase, the worm 340 is almost stationary, and there is static friction between the worm 340 and the worm wheel 341. Since the static friction is greater than the dynamic friction, there is a situation where the lead angle is less than the friction angle of the worm 340. Therefore, the torque of the reset torsion spring 342 must be much greater than the static friction torque of the worm 340 to satisfy the driving condition of the worm wheel 341 driving the worm 340 in the desired direction.
[0037] When the earthquake stops and the worm gear 340 stops rotating, the reset torsion spring 342 is activated. The torque of the reset torsion spring 342 is greater than the static friction torque threshold of the worm gear 340. Under the action of the reset torsion spring 342, the worm wheel 341 drives the worm gear 340 to rotate in the opposite direction. Through the reverse output of the acceleration component 310, the wall panel 300 is driven to return to its original position along the arc rack 203. Example
[0038] Reference Figure 10 As shown, this invention discloses a construction method for an isolation wall structure in a water plant area, comprising: S1. Connect the dual gyroscope rotor assembly 320, cam 330, and worm gear 340 to the output shaft of the acceleration assembly 310 respectively; The dual gyroscope rotor assembly 320, cam 330, worm gear 340, and acceleration assembly 310 are respectively installed within the housing 302, and connected according to the energy transmission direction. Specifically, one end of the output shaft of the acceleration assembly 310 is connected to the central drive shaft 321 in the dual gyroscope rotor assembly 320 via a one-way bearing 323, enabling the acceleration assembly 310 to drive the central drive shaft 321 to rotate in one direction. The other end of the output shaft of the acceleration assembly 310 is connected to the rotation shaft of the cam 330, and also to the end of the worm gear 340. The output shaft of the acceleration assembly 310 has a bidirectional driving relationship with the cam 330 and the worm gear 340.
[0039] S2. Install the dual gyroscope rotor assembly 320, cam 330, worm gear 340 and acceleration assembly 310 into the space reserved in the wall panel 300, connect the input end of the acceleration assembly 310 to the power gear 304, and mesh the power gear 304 at the lower end of the swing arm 303 with the arc rack 203.
[0040] The dual gyroscope rotor assembly 320, cam 330, worm gear 340, acceleration assembly 310, additional components, and housing 302 are simultaneously installed in the wall plate 300. The second transmission bevel gear 307 is meshed with the first transmission bevel gear 305, which is coaxially connected to the power gear 304, so that the power gear 304 drives the second transmission bevel gear 307 to rotate, thereby providing power input to the acceleration assembly 310.
[0041] S3. The wall panel 300 is hoisted as a whole between the upper beam 100 of the wall and the base 200 of the wall. The top of the wall panel 300 is rotatably connected to the upper beam 100 of the wall, and the ball head 301 at the bottom of the wall panel 300 is aligned with the ball socket 201. The wall panel 300 is hoisted as a whole between the upper beam 100 and the wall base 200 using hoisting equipment. The position of the wall panel 300 is adjusted so that the top of the wall panel 300 is connected to the upper beam 100 via a universal joint 101, facilitating the swinging of the wall panel 300. The bottom end of the wall panel 300 is welded and fixed to the ball head 301, which is aligned with the inside of the ball socket 201. When the wall panel 300 is in its natural state, the center of the ball head 301 and the center of the ball socket 201 are located on the same vertical line of gravity.
