Description

Technical Field

[0001] This invention relates to the field of silo reinforcement technology, specifically a silo reinforcement structure based on prestressing technology. Background Technology

[0002] Silo reinforcement devices are designed to enhance the load-bearing capacity, stability, and durability of silos, improving their ability to resist external forces (such as material lateral pressure, wind load, and seismic action) during material storage. This prevents problems like cracks, deformation, and even collapse. Through welding, bolting, and bonding fiber composite materials, structural components or systems such as steel support structures, carbon fiber reinforcement layers, prestressed tie rod systems, and ring-shaped steel strap restraint devices are added or modified to the silo's main structure. These measures effectively extend the silo's service life and ensure its safe operation.

[0003] For example, Chinese Patent Publication No. CN110424551B describes a reinforcement device and method for fixing large-sized arc-shaped embedded parts for the outer wall of a silo. The device includes reinforcing bars and anchor bars between a steel template and the embedded part. The steel template includes an inner arc steel template and an outer arc steel template. Each anchor bar includes a threaded connecting anchor bar and an unthreaded supporting anchor bar. Each anchor bar is fixedly connected to the embedded part. The ends of each reinforcing bar are threaded and used in conjunction with the connecting anchor bar through positive and negative thread sleeves. A PVC pipe is provided outside the positive and negative thread sleeves. The PVC pipe is connected to the inner arc steel template through a rubber plug.

[0004] When silos are used to store high-density granular materials such as ores and cement, the weight of the materials and their stacking characteristics exert continuous and significant circumferential lateral pressure on the silo walls. Under these conditions, traditional reinforcement methods such as bonding fiber composite materials or adding steel supports are essentially passive load-bearing systems, providing only limited resistance after the structure deforms under stress, and are prone to stress concentration or excessive deformation. Summary of the Invention

[0005] The purpose of this invention is to provide a silo reinforcement structure based on prestressed technology to solve the problems mentioned in the background art, which are that due to the weight and accumulation characteristics of the material itself, a continuous and significant circumferential lateral pressure will be generated on the silo wall. Traditional reinforcement methods such as bonding fiber composite materials or adding steel supports can only provide limited resistance after the structure is deformed by stress, and are prone to stress concentration or deformation exceeding the limit.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silo reinforcement structure based on prestressing technology, comprising a silo body, wherein a plurality of positioning rods are fixedly installed in a ring arrangement inside the silo body, a plurality of prestressing reinforcement components are provided inside the silo body, and a material storage bag is also provided inside the silo body, the material storage bag being disposed inside the plurality of prestressing reinforcement components, the prestressing reinforcement components comprising a first ring, a reset water bag and an arc plate, an adjusting cylinder being fixedly connected to the middle of one side of the arc plate, connectors being symmetrically fixedly connected to the inner side of the first ring, the connectors being made of synthetic rubber, one end of the connectors being movably engaged inside the adjusting cylinder, the two sides of the reset water bag being fixedly bonded to the inner side of the first ring and one side of the arc plate respectively, and one end of the reset water bag being fixedly connected to a water storage component.

[0007] Preferably, rubber sleeves are fixedly bonded to both ends of the arc-shaped plate. The rubber sleeves are used to prevent the edges of the arc-shaped plate from being squeezed and contacted with the material storage bag.

[0008] Preferably, a No. 1 positioning ring is provided at the upper end of the silo body, and several threaded rods are fixedly installed on one side of the No. 1 positioning ring in a ring arrangement.

[0009] Preferably, a second positioning ring is fixedly connected to one end of the material storage bag. The second positioning ring has several positioning holes arranged in a ring. Several threaded rods are movably inserted through the interior of the positioning holes. A nut is threaded to one end of each threaded rod and fits against one side of the positioning hole.

[0010] Preferably, a slider is fixedly installed on the outer side of the first ring in a centrally symmetrical manner, and a circular hole is opened inside the slider, through which the positioning rod moves.

[0011] Preferably, the reset water bag includes two sub-water storage bags and a connecting bag, with both ends of the connecting bag fixedly connected to one side of each of the two sub-water storage bags, and the connecting bag is disposed between the two connectors.

[0012] Preferably, one side of the connecting bag is fixedly connected to the water storage component, and the water from the two sub-water storage bags is guided into the interior of the water storage component through the connecting bag.

[0013] Preferably, the water storage component includes a drain pipe, a water storage bag, a micro water pump, a water outlet pipe, and an electrically controlled valve. One end of the drain pipe is fixedly connected to the input end of the water storage bag, the output end of the water storage bag is fixedly connected to the input end of the micro water pump, the output end of the micro water pump is fixedly connected to one end of the water outlet pipe, the other end of the water outlet pipe is fixedly connected to one end of the electrically controlled valve, and the other end of the electrically controlled valve is fixedly connected to one side of the drain pipe.

[0014] Preferably, a lifting ring is fixedly installed on the outer side of the first ring in a centrally symmetrical manner. The lifting ring is used to secure the rope of the hoisting equipment.

[0015] Preferably, the material storage bag is made of polyester fiber.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, before filling the material, the interior of the water bag is filled with sufficient water, and the arc-shaped plate is pushed toward the axis inside the silo body as a pre-applied radial stress. During the filling process, the material comes into contact with the arc-shaped plate, and the pre-applied radial stress offsets the squeezing force generated during the material storage process, thereby making the silo reinforcement structure less prone to cracking and deformation under normal use.

[0017] 2. In this invention, when the material is taken out of the material storage bag, the electric control valve opens and the micro water pump pumps the water storage bag out. The water enters the interior of the connecting bag through the water outlet pipe, the electric control valve, and the drainage pipe in sequence, and then enters the interior of the two sub-water storage bags through the connecting bag. After the sub-water storage bags are replenished with enough water, they will expand to their maximum volume, causing the arc plate to reset and forming prestress again to offset the squeezing force when storing materials next time.

[0018] 3. In this invention, the prestressed reinforcement components are disassembled and maintained to ensure that they can stably output prestress, thereby improving the stability and safety of materials stored in silos. Regular maintenance can promptly detect and address potential problems such as local wear and sealing failure of the prestressed components. Attached Figure Description

Detailed Implementation

[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Refer to Figures 1-6 As shown: A silo reinforcement structure based on prestressing technology includes a silo body 1. Several positioning rods 2 are fixedly installed in a ring arrangement inside the silo body 1. Several prestressing reinforcement components 3 are arranged inside the silo body 1. A material storage bag 4 is also arranged inside the silo body 1, positioned inside the prestressing reinforcement components 3. Each prestressing reinforcement component 3 includes a first ring 31, a reset water bag 32, and an arc-shaped plate 33. An adjusting cylinder 331 is fixedly connected to the middle of one side of the arc-shaped plate 33. The first ring 31... A connector 311 is symmetrically fixedly connected to the inner side of the material storage bag 4. The material of the connector 311 is synthetic rubber. One end of the connector 311 is movably snapped into the inside of the adjusting cylinder 331. The two sides of the reset water bag 32 are respectively fixedly bonded to the inner side of the first ring 31 and one side of the arc plate 33. One end of the reset water bag 32 is fixedly connected to the water storage component 34. The two ends of the arc plate 33 are respectively fixedly bonded to the rubber soft sleeve 332. The rubber soft sleeve 332 is used to prevent the edge of the arc plate 33 from squeezing and contacting the material storage bag 4. The material storage bag 4 is made of polyester fiber.

[0023] In this embodiment, the material to be stored is poured into the material storage bag 4. The material accumulates at the bottom of the material storage bag 4, and the outer diameter of the bottom of the material storage bag 4 gradually expands, so that the bottom of the material storage bag 4 contacts the arc plate 33 and radially compresses it. The pressure is transmitted through the arc plate 33 to the interior of the reset water bag 32, so that the water inside the reset water bag 32 is squeezed into the interior of the water storage component 34. At the same time, one end of the connector 311 extends into the interior of the adjusting cylinder 331. As the material is gradually replenished, the material storage bag 4 compresses the arc plates 33 inside several prestressed reinforcement components 3 from bottom to top. Before filling the material, the reset water bag 32 stores enough water to push the arc plate 33 towards the axis inside the silo body 1 as a pre-applied radial stress. During the filling process, the material contacts the arc plate 33, and the pre-applied radial stress offsets the compressive force generated during the material storage process, thereby making the silo reinforcement structure less prone to cracking and deformation under normal use.

[0024] The material storage bag 4, made of polyester fiber, possesses excellent tensile strength, effectively bearing the heavy pressure of high-density materials. It also exhibits superior wear resistance, resisting damage even under frequent loading, unloading, and friction, reducing the risk of material leakage due to bag rupture and ensuring the safety and integrity of materials stored within the silo. Furthermore, the lightweight nature of polyester fiber significantly reduces the added weight inside the silo compared to traditional metal or heavy fabric storage bags, lowering the load-bearing requirements on the silo's main structure 1. Its soft texture facilitates cutting and installation, allowing for flexible adjustment to suit the internal shape of the silo and a tight fit with the prestressed reinforcement component 3, maximizing their synergistic effect.

[0025] The rubber sleeves 332 at both ends of the arc plate 33 can prevent the edge of the arc plate 33 from squeezing into the material storage bag 4 and hooking the material storage bag 4, thus ensuring that the material storage bag 4 can effectively and safely contact the arc plate 33.

[0026] Example 2: Figures 1-8As shown, the silo reinforcement structure based on prestressing technology in this invention includes a silo body 1. Several positioning rods 2 are fixedly installed in a ring arrangement inside the silo body 1. Several prestressing reinforcement components 3 are arranged inside the silo body 1. A material storage bag 4 is also arranged inside the silo body 1, positioned inside the prestressing reinforcement components 3. The prestressing reinforcement component 3 includes a first ring 31, a reset water bag 32, and an arc-shaped plate 33. An adjusting cylinder 331 is fixedly connected to the middle of one side of the arc-shaped plate 33. Connectors 311, made of synthetic rubber, are symmetrically fixedly connected to the inner side of the first ring 31. One end of the connector 311 is movably engaged inside the adjusting cylinder 331. The two sides of the reset water bag 32 are fixedly adhered to the inner side of the first ring 31 and one side of the arc-shaped plate 33, respectively. One end of the reset water bag 32 is fixedly connected to a water storage component 34. 32 includes two sub-water storage bags 321 and a connecting bag 322. The two ends of the connecting bag 322 are fixedly connected to one side of each of the two sub-water storage bags 321. The connecting bag 322 is located between two connectors 311. One side of the connecting bag 322 is fixedly connected to the water storage component 34. The water from the two sub-water storage bags 321 is guided into the water storage component 34 through the connecting bag 322. The water storage component 34 includes a drain pipe 341, a water storage bag 342, a micro water pump 343, a water outlet pipe 344, and an electrically controlled valve 345. One end of the drain pipe 341 is fixedly connected to the input end of the connecting bag 322. The output end of the water storage bag 342 is fixedly connected to the input end of the micro water pump 343. The output end of the micro water pump 343 is fixedly connected to one end of the water outlet pipe 344. The other end of the water outlet pipe 344 is fixedly connected to one end of the electrically controlled valve 345. The other end of the electrically controlled valve 345 is fixedly connected to one side of the drain pipe 341.

[0027] In this embodiment, when the material is taken out from the material storage bag 4, the electrically controlled valve 345 opens, and the micro water pump 343 pumps out the water storage bag 342. The water enters the interior of the connecting bag 322 through the water outlet pipe 344, the electrically controlled valve 345, and the drainage pipe 341 in sequence. Then, it enters the interior of the two sub-water storage bags 321 through the connecting bag 322. After the sub-water storage bags 321 are replenished with sufficient water, they will expand to their maximum volume, causing the arc plate 33 to reset and form prestress again to offset the squeezing force when storing materials next time.

[0028] Example 3: According to Figures 1-9As shown, the silo reinforcement structure based on prestressing technology in this invention includes a silo body 1. Several positioning rods 2 are fixedly installed in a ring arrangement inside the silo body 1. Several prestressing reinforcement components 3 are arranged inside the silo body 1. A material storage bag 4 is also arranged inside the silo body 1, positioned inside the prestressing reinforcement components 3. The prestressing reinforcement component 3 includes a first ring 31, a reset water bag 32, and an arc-shaped plate 33. An adjusting cylinder 331 is fixedly connected to the middle of one side of the arc-shaped plate 33. Connectors 311 are symmetrically fixedly connected to the inner side of the first ring 31. The connectors 311 are made of synthetic rubber, and one end of the connector 311 is movably engaged inside the adjusting cylinder 331. The two sides of the reset water bag 32 are respectively fixedly adhered to the inner side of the first ring 31 and one side of the arc-shaped plate 33. One end is fixedly connected to a water storage component 34. A first positioning ring 11 is provided on the upper end of the silo body 1. Several threaded rods 12 are fixedly installed on one side of the first positioning ring 11 in a circular arrangement. A second positioning ring 41 is fixedly connected to one end of the material storage bag 4. Several positioning holes 42 are opened in a circular arrangement inside the second positioning ring 41. Several threaded rods 12 are movably inserted through the interior of several positioning holes 42. A nut is threadedly connected to one end of several threaded rods 12. The nut fits against one side of the positioning hole 42. A slider 312 is fixedly installed on the outer side of the first ring 31 in a centrally symmetrical manner. A circular hole 313 is opened inside the slider 312. The positioning rod 2 movably inserts through the interior of the circular hole 313. A lifting ring 314 is fixedly installed on the outer side of the first ring 31 in a centrally symmetrical manner. The lifting ring 314 is used to fix the rope of the hoisting equipment.

[0029] In this embodiment, when the prestressed reinforcement component 3 needs maintenance, the first positioning ring 11 is removed, the hoisting equipment rope is tied and fixed to the outside of the lifting ring 314, and the prestressed reinforcement component 3 is hoisted out from the inside of the silo body 1. During the hoisting process, the prestressed reinforcement component 3 will rise vertically along the direction of the positioning rod 2 until the positioning rod 2 slides out from the inside of the round hole 313 of the slider 312. By disassembling and maintaining the prestressed reinforcement component 3, it is ensured that it can stably output prestress to improve the stability and safety of the materials stored in the silo. Regular maintenance can promptly detect and deal with potential problems such as local wear and sealing failure of the prestressed component, and prevent the problem from escalating through targeted maintenance. For example, the sealing performance of the reset water bag 32 and the elasticity check of the connector 311 are checked to ensure that the performance of each component is always in the best condition and to extend the overall service life of the reinforcement system.

[0030] The method of use and working principle of this device: The material to be stored is poured into the material storage bag 4. The material accumulates at the bottom of the material storage bag 4, gradually widening the outer diameter of the bottom end. This causes the bottom end of the material storage bag 4 to contact the arc-shaped plate 33 and be radially compressed. The pressure is transmitted through the arc-shaped plate 33 to the interior of the reset water bag 32, causing the water inside the reset water bag 32 to be squeezed into the water storage assembly 34. Simultaneously, one end of the connector 311 extends into the adjusting cylinder 331. As the material is gradually replenished, the material storage bag 4... The arc-shaped plates 33 inside several prestressed reinforcement components 3 are squeezed sequentially from bottom to top. When the material is taken out from the material storage bag 4, the electric control valve 345 is opened, and the micro water pump 343 pumps out the water storage bag 342. The water enters the interior of the connecting bag 322 through the water outlet pipe 344, the electric control valve 345, and the drainage pipe 341, and then enters the interior of the two sub-water storage bags 321 through the connecting bag 322. After the sub-water storage bags 321 are replenished with sufficient water, they will expand to their maximum volume, causing the arc-shaped plates 33 to reset and form prestress again.

[0031] When the prestressed reinforcement component 3 needs to be inspected, remove the first positioning ring 11, tie and fix the rope of the hoisting equipment to the outside of the lifting ring 314, and hoist the prestressed reinforcement component 3 out of the silo body 1. During the hoisting process, the prestressed reinforcement component 3 will rise vertically along the direction of the positioning rod 2 until the positioning rod 2 slides out from the inside of the round hole 313 of the slider 312.

[0032] Although the present invention 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 invention should be included within the protection scope of the present invention.
