Description

Technical Field

[0001] The invention relates to the technical field of ultra-high voltage power transmission, and in particular to an ultra-high voltage power transmission fireproof iron tower. Background Art

[0002] With the rapid development of the economy, the demand for electricity continues to grow. UHV transmission has the advantages of large transmission capacity, long distance and low loss, and has become an important means to meet large-scale power transmission. However, UHV transmission lines often span vast areas, pass through various complex terrains and environments, and face many potential safety risks, among which fire is a major threat. In order to ensure the safe and stable operation of UHV transmission lines, effective fire prevention measures must be taken. The emergence of fireproof towers provides an important technical means to solve this problem.

[0003] However, the UHV fireproof iron towers produced by the existing methods have some defects in use. The fire prevention method is single, and fire prevention work is not carried out by comprehensively utilizing fireproof materials, optimizing structural design, and strengthening monitoring and early warning measures, resulting in poor fire prevention effects, reducing the fireproof performance of the UHV fireproof iron towers, increasing fire risks, and reducing the reliability of power transmission, which cannot meet the needs of today's market.

[0004] To this end, we provide a UHV transmission fireproof iron tower to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the present invention is to provide a UHV power transmission fireproof iron tower, which solves some defects in the use of UHV power transmission fireproof iron tower in the prior art by comprehensively utilizing fireproof materials, optimizing structural design and strengthening monitoring and early warning measures. The fire prevention method is single, and fire prevention work is not carried out comprehensively utilizing fireproof materials, optimizing structural design and strengthening monitoring and early warning measures, resulting in poor fire prevention effect, reducing the fireproof performance of the UHV power transmission fireproof iron tower, increasing fire risks, reducing the reliability of power transmission, and failing to meet the current market demand.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a fireproof iron tower for ultra-high voltage power transmission, and the production method thereof comprises the following steps:

[0008] Step a: Steel selection: Carefully select steel with excellent high temperature resistance and flame retardant properties. When exposed to high temperatures, this type of steel will deform very little and its strength will decrease only slightly, which can effectively maintain the structural stability of the tower;

[0009] Step b: Fire retardant coating identification: It is very important to select high-quality fire retardant coating. This coating should have strong adhesion, be able to firmly adhere to the surface of the tower, and withstand the test of various harsh environments. At the same time, it should have good weather resistance and resist the erosion of natural factors such as wind, sun, rain, snow, etc. for a long time without failure;

[0010] Step c: Selection of auxiliary fireproof materials: Comprehensively evaluate auxiliary fireproof materials such as fireproof boards. Fireproof boards should have excellent fireproof performance and be able to further enhance the fireproof effect of the tower at key locations. Strictly screen the material, thickness, fireproof grade and other parameters of the fireproof boards to ensure that they match the overall fireproof design of the tower.

[0011] Step d: Design: Carry out detailed design according to the tower's use requirements and installation environment. During the design process, factors such as the tower's height, span, load-bearing capacity, and fire resistance need to be considered. Use professional design software to perform structural analysis and optimization to ensure the tower's safety and stability.

[0012] Step e: Processing and manufacturing: Steel processing: Use cutting, welding, drilling and other processes to process the steel into the required shape and size. The welding quality needs to be strictly controlled during the welding process to ensure the strength and sealing of the weld. Aluminum alloy processing: Use extrusion, casting and other processes to process the aluminum alloy into the required components. Surface treatment: Surface treatment of the components of the tower, such as rust removal, spraying of anti-corrosion coatings, etc., to improve the corrosion resistance of the tower;

[0013] Step f: Fireproofing: Fireproofing steel materials, such as applying fireproof coatings and installing fireproof panels. Fireproof coatings can form a heat-insulating layer at high temperatures, slowing down the temperature rise of steel materials and improving the fireproofing performance of the tower. Fireproof panels can be directly installed on the surface of the tower to play a role in heat insulation and fire prevention.

[0014] Step g: Assemble: Assemble the processed parts by bolting or welding to ensure that the overall structure of the tower is firm and reliable. During the assembly process, it is necessary to strictly follow the design requirements to ensure the dimensional accuracy and installation quality of the tower;

[0015] Step h: Quality inspection: Conduct quality inspection on the completed towers, including appearance inspection, dimension measurement, strength test, fire performance test, etc., to ensure that the quality of the towers meets the relevant standards and requirements;

[0016] Step i: Installation and commissioning: At the installation site, the tower is installed and commissioned according to the design requirements. During the installation process, attention should be paid to safety to ensure the quality of installation. After the installation is completed, advanced fire monitoring equipment such as temperature sensors, smoke alarms, etc. are installed on the tower. These devices can monitor the environmental changes around the tower in real time. Once signs of fire are found, an alarm will be sounded immediately. Through the intelligent monitoring system, all-round and real-time monitoring of the tower can be achieved, and then commissioning and acceptance are carried out to ensure that the performance indicators of the tower meet the requirements.

[0017] The present invention is further configured such that the steel in step a is subjected to strict quality inspection and performance evaluation to ensure that it meets the stringent requirements of ultra-high voltage transmission fireproof iron towers.

[0018] The present invention is further configured such that the most critical point in step b is that its fireproof performance must be excellent, and when a fire occurs, a solid heat-insulating protective layer can be quickly formed to effectively prevent the spread of the fire and provide reliable protection for the iron tower.

[0019] The present invention is further configured such that the fire retardant coating in step b is selected from thick steel structure fire retardant coating and ultra-thin fire retardant coating. The thick steel structure fire retardant coating has the characteristics of thick coating and high fire resistance limit. It can form a thick heat-insulating carbonized layer when a fire occurs to prevent heat from being conducted to the steel of the tower, thereby protecting the tower structure. Although the ultra-thin fire retardant coating has a very thin coating, it has good fire retardant performance and decorative effect. It is easy to construct and has little effect on the appearance of the tower. At the same time, it can improve the corrosion resistance of the tower to a certain extent.

[0020] The present invention is further configured that the fireproof board in step c is selected from calcium silicate fireproof board and rock wool composite fireproof board. The calcium silicate fireproof board has the advantages of being non-flammable, high temperature resistant, high strength, moisture-proof, etc., and can be used as the outer protective material of the iron tower, directly installed on the surface of the iron tower, and effectively blocking flames and high temperatures. The rock wool composite fireproof board is composed of rock wool and metal panels, and has both the good thermal insulation performance of rock wool and the strength of metal panels. When used in the iron tower, it can play a role in heat insulation, fire prevention and enhancing structural stability.

[0021] The present invention is further configured as follows: in the step d, the iron tower structure is optimized: professional structural engineers use advanced design software and technology to deeply optimize the iron tower structure, minimize the parts that are prone to fire, and avoid too many sharp angles and gaps, because these parts are prone to accumulate sparks and become potential fire hazards. Through reasonable design, the appearance of the iron tower is made smoother and the risk of fire spreading is reduced.

[0022] The present invention is further configured as follows: fire isolation measures are added in the step d: fire isolation belts are scientifically arranged at different parts of the iron tower to form solid fire barriers. These isolation belts can be made of high temperature resistant and flame retardant materials, which can effectively prevent the fire from spreading rapidly inside the iron tower. Through reasonable layout and design, it is ensured that the fire isolation belts play the greatest role at critical moments.

[0023] The present invention is further configured such that, in step f, before applying the fireproof material, it is necessary to ensure that the surface of the tower is clean and free of impurities such as oil, dust, rust, etc., and can be cleaned using a high-pressure water gun, detergent, etc. to ensure that the surface meets the painting requirements.

[0024] The present invention is further configured such that a complete early warning system is established in step i and linked with the fire department. When the monitoring equipment issues an alarm, the early warning system can quickly transmit the information to the fire department to ensure that effective fire-fighting measures can be taken quickly when a fire occurs. At the same time, the early warning system can also send notifications to relevant personnel to remind them to take risk avoidance measures in a timely manner.

[0025] The present invention has the following beneficial effects:

[0026] Improve power transmission safety:

[0027] 1. Effectively reduce the risk of fire: The fireproof iron tower adopts special fireproof materials and design, which can resist the invasion of fire to a large extent, reduce the damage to the iron tower and transmission line failure caused by fire, ensure the stable transmission of electricity, and provide reliable power guarantee for production and life.

[0028] 2. Enhanced structural stability: Even in the event of a fire, the fireproof iron tower can maintain good structural integrity and is not easily deformed or collapsed due to high temperature, reducing the safety threat to the surrounding environment and personnel.

[0029] Reduce economic losses:

[0030] 1. Reduce maintenance costs: Since fire-resistant iron towers have strong fire resistance, they can reduce the damage caused by fire to the iron towers, thereby reducing the cost of repairing and replacing the iron towers. At the same time, it also reduces production losses and socio-economic impacts caused by power outages.

[0031] 2. Extend service life: Fireproof materials and optimized structural design make the tower more durable, able to withstand longer-term use and the test of various harsh environments, extending the service life of the tower and reducing the overall investment cost.

[0032] Protect the environment:

[0033] 1. Reduce the risk of forest fires: UHV transmission lines often pass through natural areas such as forests. The use of fire-proof towers can reduce the possibility of forest fires caused by transmission lines and protect the ecological environment and natural resources.

[0034] 2. Reduce fire pollution: In the event of a fire, the fireproof tower can reduce the emission of pollutants produced by combustion, reduce pollution to the air, soil and water sources, and is beneficial to environmental protection. DETAILED DESCRIPTION

It can form a thick heat-insulating carbonized layer when a fire occurs to prevent heat from being transmitted to the steel of the iron tower, thereby protecting the iron tower structure. Although the coating of the ultra-thin fire retardant coating is very thin, it has good fire retardant performance and decorative effect. It is easy to construct and has little effect on the appearance of the iron tower. At the same time, it can improve the corrosion resistance of the iron tower to a certain extent.

[0092] Step c: Selection of auxiliary fireproof materials: Comprehensively evaluate auxiliary fireproof materials such as fireproof boards. Fireproof boards should have excellent fireproof performance and can further enhance the fireproof effect of the iron tower at key locations. Strictly screen the material, thickness, fireproof grade and other parameters of the fireproof boards to ensure that they match the overall fireproof design of the iron tower. In step c, calcium silicate fireproof boards and rock wool composite fireproof boards are selected for fireproof boards. Calcium silicate fireproof boards: have the advantages of being non-flammable, high temperature resistant, high strength and moisture-proof. They can be used as the outer protective material of the iron tower and directly installed on the surface of the iron tower to effectively block flames and high temperatures. Rock wool composite fireproof boards: are composited from rock wool and metal panels, and have both the good thermal insulation performance of rock wool and the strength of metal panels. When used in iron towers, they can play a role in heat insulation, fire prevention and enhanced structural stability.

[0093] Step d: Design: Carry out detailed design according to the use requirements and installation environment of the iron tower. During the design process, factors such as the height, span, bearing capacity, and fire resistance of the iron tower need to be considered. Use professional design software to perform structural analysis and optimization to ensure the safety and stability of the iron tower. Optimize the iron tower structure in step d: Professional structural engineers use advanced design software and technology to deeply optimize the iron tower structure, minimize the parts that are prone to ignition, and avoid too many sharp angles and gaps, because these parts are prone to accumulate sparks and become potential hidden dangers of fire. Through reasonable design, make the shape of the iron tower more smooth and reduce the risk of fire spread. Add fire isolation measures in step d: Scientifically set fire isolation belts at different parts of the iron tower to form a solid fire barrier. These isolation belts can be made of high temperature resistant and flame retardant materials, which can effectively prevent the rapid spread of fire inside the iron tower. Through reasonable layout and design, ensure that the fire isolation belt plays the greatest role at critical moments;

[0094] Step e: Processing and manufacturing: Steel processing: Use cutting, welding, drilling and other processes to process the steel into the required shape and size. The welding quality needs to be strictly controlled during the welding process to ensure the strength and sealing of the weld. Aluminum alloy processing: Use extrusion, casting and other processes to process the aluminum alloy into the required components. Surface treatment: Surface treatment of the components of the tower, such as rust removal, spraying of anti-corrosion coatings, etc., to improve the corrosion resistance of the tower;

[0095] Step f: Fireproofing: Fireproofing steel materials, such as applying fireproof coatings and installing fireproof panels. Fireproof coatings can form a heat-insulating layer at high temperatures, slowing down the temperature rise of steel materials and improving the fireproofing performance of the tower. Fireproof panels can be directly installed on the surface of the tower to play a role in heat insulation and fire prevention.

[0096] Step g: Assemble: Assemble the processed parts by bolting or welding to ensure that the overall structure of the tower is firm and reliable. During the assembly process, it is necessary to strictly follow the design requirements to ensure the dimensional accuracy and installation quality of the tower;

[0097] Step h: Quality inspection: Conduct quality inspection on the completed towers, including appearance inspection, dimension measurement, strength test, fire performance test, etc., to ensure that the quality of the towers meets the relevant standards and requirements;

[0098] Step i: Installation and commissioning: At the installation site, the tower is installed and commissioned according to the design requirements. During the installation process, attention should be paid to safety to ensure the quality of installation. After the installation is completed, advanced fire monitoring equipment such as temperature sensors, smoke alarms, etc. are installed on the tower. These devices can monitor the environmental changes around the tower in real time. Once signs of fire are found, an alarm will be sounded immediately. Through the intelligent monitoring system, all-round and real-time monitoring of the tower can be achieved, and then commissioning and acceptance are carried out to ensure that the performance indicators of the tower meet the requirements.
