Description

Technical Field

[0001] The present invention relates to the technical field of airport construction equipment, and in particular to a protection device and a protection method for a visual navigation light tower. Background Art

[0002] A visual aid lighting tower is a type of navigational aid used primarily to provide pilots with precise visual guidance. Mounted on top of the tower is an aviation obstruction light, which flashes at a constant frequency at night or in low visibility conditions, drawing pilots' attention and enabling them to identify the tower's location and height. Furthermore, visual aid lighting towers serve the following functions: Preventing aviation accidents: By providing clear flight guidance, visual aid lighting towers help prevent accidents. Improving flight efficiency: Pilots can more accurately determine flight direction and altitude based on the guidance provided by visual aid lighting towers, thereby improving flight efficiency. Enhancing safety: The presence of visual aid lighting towers enhances overall airport safety, especially in complex weather conditions. In short, visual aid lighting towers are an indispensable part of airports, playing a vital role in ensuring flight safety and improving flight efficiency.

[0003] With the improvement of people's living standards, air transportation has also increased significantly, and the demand for airports has increased accordingly. For some early-built airports, in order to cope with the significant increase in air transportation, they generally adopt the method of expanding the airport. However, there are many hilly areas in my country, especially in Yunnan, Guizhou and Sichuan. If these airports built in hilly areas need to be expanded, a large amount of earth and stone will need to be landfilled in the expansion area to increase the height to the same as the original runway. Some airport expansions need to be carried out without stopping flights. The area where visual aids to navigation lighting towers are built is generally around the airport, and some are part of the expansion area. In order to ensure that the area where visual aids to navigation lighting towers are built without stopping flights, the normal operation of the visual aids to navigation lighting towers must be guaranteed. This raises a problem for the safety protection of visual aids to navigation lighting towers. Currently, there is no matching equipment and technology to ensure that large amounts of earth and stone are landfilled in this area while the visual aids to navigation lighting towers are in normal use. Some of the landfill areas currently encountered need to reach a height of about 45 meters, almost completely filling the visual aids to navigation lighting towers. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a protection device and protection method for the visual aid lighting tower, so as to solve the problem of landfilling the visual aid lighting tower area without stopping flights at the airport and protecting the safe use of the visual aid lighting tower during the landfill process.

[0005] The present invention is achieved through the following technical solutions:

[0006] A protective device for a visual navigational light tower comprises a light tower, wherein multiple layers of concrete protective round blocks are sequentially cast upward from the bottom of the light tower, each layer of concrete protective round blocks having a height between 1.8m and 2.2m.

Each buffer arc block is connected to the winch set on the top of the lighting tower through a lifting rope. When the area around one layer of concrete protection round blocks is filled with earth and stone, all the buffer arc blocks are lifted to the position of the next layer of concrete protection round blocks by the winch, and the area around the concrete protection round blocks of this layer continues to be filled with earth and stone until the earth and stone are filled to the set height.

[0008] Furthermore, a T-shaped sliding groove is provided in the longitudinal direction of the annular surface of the concrete protection circle corresponding to each buffer arc block, and the T-shaped sliding grooves between two adjacent layers of concrete protection circle blocks are smoothly transitioned and connected.

[0009] Furthermore, a set of fixed pulleys is provided on the top of the lighting tower corresponding to each buffer arc block, and the suspension rope is connected to the winch through the fixed pulleys.

[0010] Furthermore, the damping cylindrical barrels are spliced inside the lighting tower. When a connecting reinforcement layer is provided inside the lighting tower, the damping cylindrical barrels are divided into multiple sections. A damping cylindrical barrel is provided between two layers of connecting reinforcement layers. The two adjacent damping cylindrical barrels are connected by cables. After concrete protective blocks are poured around a section of the damping cylindrical barrel, the concrete is poured into the damping cylindrical barrel.

[0011] Furthermore, the buffer arc block includes an inner arc plate frame, an outer arc plate frame and an end arc plate frame. The inner arc opening of the outer arc plate frame is movably buckled on the outer arc opening of the inner arc plate frame. A supporting connecting shaft passing through the outer arc plate frame is provided on the inner arc plate frame. A buffer spring is sleeved on the supporting connecting shaft between the outer arc plate frame and the inner arc plate frame. The two ends of the outer arc plate frame are movably buckled with the end arc plate frame respectively, and a tensioning spring is provided between the end arc plate frame and the end of the outer arc plate frame.

A connecting block is provided in the middle of the inner arc surface of the inner arc vertical plate. A limiting plate is hinged on the connecting block. The connecting block and the limiting plate are limitedly installed in the T-shaped slide groove. A supporting connecting shaft is provided in the middle of the outer arc surface of the inner arc vertical plate.

[0013] Furthermore, the outer arc plate frame includes an outer arc vertical plate, an upper outer arc plate and a lower outer arc plate. The upper outer arc plate and the lower outer arc plate are provided on the upper and lower end surfaces of the outer arc vertical plate respectively. The inner arc surface of the outer arc vertical plate is respectively provided with end arc plate frame connecting plates, and the end arc plate frame connecting plates are provided with strip grooves.

[0014] Furthermore, the end arc plate frame includes an end arc vertical plate, an upper end arc plate, a lower end arc plate and an end end plate, and the upper end arc plate and the lower end plate are provided on the upper and lower end surfaces of the end arc vertical plate respectively. The outer ends of the end arc vertical plate, the upper end arc plate and the lower end arc plate are connected through the end end plate seal, and a guide rod is provided on the inner surface of the end end plate, and a tensioning spring is sleeved on the guide rod, and the guide rod is movably inserted into the strip groove on the connecting plate of the end arc plate frame; a limit block is provided on the inner surface of the upper end arc plate to block the front end of the upper outer arc plate.

The limiting rotating shaft head is provided with a rotating shaft head connecting hole, and the two adjacent limiting rotating shaft heads on the adjacent buffer arc blocks are movably inserted into the rotating shaft head connecting holes of the two limiting rotating shaft heads through a sliding connecting shaft.

[0016] The present invention is also achieved through the following another technical solution:

[0017] A method for protecting a visual navigation light tower comprises the following steps:

[0018] Step 1: Move the cables on the lighting tower in the earth-filled area to the top of the tower, clean up the debris at the bottom of the lighting tower, and prepare for the protection construction of the lighting tower 1;

[0019] Step 2: Assemble the damping cylinder barrel inside the lighting tower, and then connect it to the top of the lighting tower with a cable to suspend it;

[0020] Step 3: Starting from the bottom of the lighting tower, a casting mold for the first layer of concrete protection round blocks is set up. The casting mold includes an outer ring mold, a T-shaped slide mold is set on the outer ring mold, and a damping circular hole mold for setting up the casting concrete protection round blocks. The damping circular hole mold is provided with a damping spring connector;

[0021] Step 4: After the casting mold is set up, pour concrete into the casting mold to form a layer of concrete protective blocks;

[0022] Step 5: After the concrete protective round block is solidified, remove the casting mold and use the damping spring to connect the damping cylinder barrel to the damping spring connector on the concrete protective round block;

[0023] Step 6: Setting up a casting mold for the next layer of concrete protection round blocks on the cast concrete protection round blocks;

[0024] Step 7: Repeat the process of setting up the casting mold for the concrete protection round block, casting the concrete protection round block in the casting mold, and installing the damping spring until the top layer of the cast concrete protection round block is 1M-1.5M higher than the height of the pre-filled earth and stone;

[0025] Step 8: pouring concrete into the damping cylinder;

[0026] Step 9: Multiple buffer arc blocks are installed around the first or second layer of concrete protective blocks. The connecting blocks and limit plates of each buffer arc block are installed in T-shaped slide grooves. Adjacent buffer arc blocks are connected by sliding connecting shafts to form a circular structure to protect the outer surface of the concrete protective block. Each buffer arc block is connected to the winch installed at the top of the lighting tower via a lifting rope.

[0027] Step 10. Fill earth and stone around the concrete protection round blocks with buffer arc blocks. When the area around one layer of concrete protection round blocks is filled with earth and stone, lift all buffer arc blocks to the position of the next layer of concrete protection round blocks by a winch. Multiple buffer arc blocks are connected to form a circular structure that changes according to the outer diameter of the concrete protection round blocks. The protection is on the outer ring surface of the concrete protection round blocks of this layer, and the area around the concrete protection round blocks of this layer continues to be filled with earth and stone until the earth and stone are filled to the set height.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] 1. The present invention provides a protective device and method for a visual navigation light tower, which employs three protective measures. The first protective measure comprises: sequentially casting multiple layers of concrete protective spheres on the light tower from the bottom upward, and integrating the concrete protective spheres with the light tower to form a "steel plate concrete" structure, thereby greatly improving the structural strength of the light tower. The second protective measure comprises: disposing a damping cylindrical barrel inside the light tower, the damping cylindrical barrel being filled with concrete. Designed according to the principle of a damper structure, when earth and rock fill creates a strong impact on the light tower, the resistance force of the damping cylindrical barrel reduces the swing of the light tower, thereby effectively preventing the light tower from tilting or deformation due to impact. The third protective measure comprises: surrounding the concrete protective spheres, with adjacent buffer arcs movably connected to form a circular ring structure protecting the outer surface of the concrete protective spheres. When earth and rock fill the area where the light tower is to be set, the earth and rock are first pressed against the buffer arcs. The buffering effect of the buffer arcs effectively eliminates some of the impact force of the earth and rock, thereby reducing the impact on the light tower.

[0030] 2. The present invention provides a protective device and method for a visual navigation light tower. Adjacent buffer arcs are flexibly connected to form a circular ring structure that protects the outer surface of the concrete protective circular blocks. Since the outer diameter of each layer of concrete protective circular blocks decreases from bottom to top, the multiple buffer arcs arranged around the structure must also follow the diameter change, otherwise the purpose of protecting the lighting tower will be lost. In addition, the buffer arcs must be relatively airtight, otherwise they will be affected by dirt or rocks and lose their buffering effect.

[0031] The present invention designs the buffer arc block into three parts: an inner arc plate frame, an outer arc plate frame and an end arc plate frame. The outer arc plate frame can achieve buffering expansion and contraction relative to the inner arc plate frame, and the end arc plate frame is connected and expanded relative to the two ends of the inner arc plate frame and the outer arc plate frame, so as to meet the diameter change requirement. At the same time, the outer arc plate frame is snapped onto the outside of the inner arc plate frame, and the end arc plate frame is snapped onto the two ends of the inner arc plate frame and the outer arc plate frame. This can not only ensure the buffering effect, but also prevent the buffer arc block from being interfered with. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Example 1

[0058] like Figures 1-13 As shown, the present invention is a protective device for a visual navigation light tower, comprising a light tower 1, as shown in FIG. Figure 1 As shown, the lighting tower 1 generally adopts a steel plate frame structure, with a height of about 50M and a general square cross-section. The top of the lighting tower 1 is equipped with an aviation obstruction light, such as Figure 2-Figure 4 As shown, the present invention casts multiple layers of concrete protection blocks 2 from the bottom of the lighting tower 1 upward in sequence, and the height of each layer of concrete protection blocks 2 is between 1.8M and 2.2M. Some reinforcing steel bars or stones can be appropriately added to the concrete protection blocks 2. Because the concrete protection blocks 2 are a temporary structure and do not need to function for a long time, the outer diameter of each layer of concrete protection blocks 2 shrinks from bottom to top in consideration of both economy and practical use, which can increase the stability of the column formed by the concrete protection blocks 2. The shortest distance between the outer ring surface of each layer of concrete protection blocks 2 and the corresponding lighting tower 1 is between 0.8M and 1.2M. In actual construction cases, the distance between the outer ring surface of the concrete protection blocks 2 and the midpoint of any surface of the corresponding lighting tower 1 is set at about 1.1 meters. The actual shortest distance is about 0.9M, which is also related to the shape of the lighting tower 1. Generally, a 50M lighting tower 1 has a pre-buried height of 30M, and the outer ring surface of the concrete protection blocks 2 is 1M away from the lighting tower, which can fully meet the structural requirements.

[0059] The poured top layer of concrete protection block 2 is 1M-1.5M higher than the height of the pre-filled earth and stone. This design is to protect the structural strength of the uncast concrete part of the lighting tower 1 to prevent damage; a damping hole 3 is reserved in the middle of each layer of concrete protection block 2. The design of the damping hole 3 is used to set the damping cylindrical barrel 4 on the one hand, and on the other hand, it can enhance the structural strength of the concrete protection block 2, and while ensuring the structural strength, it can also reduce the supporting weight of the tower body. A damping cylindrical barrel 4 is provided in the damping hole 3, and the damping cylindrical barrel 4 is connected to the top of the lighting tower 1 through a cable 5. The damping cylindrical barrel 4 is filled with concrete, and the damping cylindrical barrel 4 is connected to the concrete protection block 2 on all sides through damping springs; pouring concrete into the damping cylindrical barrel 4 is implemented only after the concrete protection blocks 2 around the damping cylindrical barrel 4 have a supporting strength, otherwise it will cause damage to the lighting tower 1.

[0060] A plurality of buffer arc blocks 6 are arranged around the first or second layer of concrete protection round blocks 2. In this embodiment, the buffer arc blocks 6 are only arranged on the second layer of concrete protection round blocks 2. No buffer arc blocks 6 may be arranged around the first layer of concrete protection round blocks 2 for earth and stone filling operations. Because the underlying structure is relatively stable, each buffer arc block 6 is slidably connected to each layer of concrete protection round blocks 2, and the movable connection between adjacent buffer arc blocks 6 forms a circular ring structure to protect the outer ring surface of the concrete protection round blocks 2. Each buffer arc block 6 is connected to the winch arranged on the top of the lighting tower 1 through a lifting rope 7. When the area around one layer of concrete protection round blocks 2 is filled with earth and stone, all the buffer arc blocks 6 are lifted to the position of the next layer of concrete protection round blocks 2 by the winch, and the area around this layer of concrete protection round blocks 2 continues to be filled with earth and stone until the earth and stone are filled to the set height.

[0061] The present invention provides a protective device for a visual navigation light tower. When performing protective construction on the light tower 1, the cables on the light tower 1 in the earth-filled rock area are moved to the top of the tower. All cables are installed from the tops of the two light towers 1, and the debris at the bottom of the light tower 1 is cleaned up, and the light tower 1 is prepared for protective construction; and safety signs are set up; a damping cylindrical barrel 4 is spliced inside the light tower 1, using pre-prepared steel plates, welded on site, and then connected to the top of the light tower 1 by a cable 5 for suspension; a casting mold for the first layer of concrete protection round blocks 2 is erected from the bottom of the light tower 1, and the casting mold includes an outer ring mold, a T-shaped slide groove mold is provided on the mold of the outer ring mold, and a damping circular hole mold is erected for casting the concrete protection round blocks 2, and the damping circular hole mold is provided. A damping spring connector is provided; these molds and corresponding device structures are matched, and the present invention will not be described in detail; after the casting mold is erected, concrete is poured into the casting mold to form a layer of concrete protection round blocks 2; after the layer of concrete protection round blocks 2 is solidified, the casting mold is removed, and the damping spring is used to connect the damping cylindrical barrel 4 to the damping spring connector on the concrete protection round blocks 2; a casting mold for casting the next layer of concrete protection round blocks 2 is erected on the cast concrete protection round blocks 2; the casting mold for the concrete protection round blocks 2 is repeatedly erected, the concrete protection round blocks 2 are cast in the casting mold, and the damping spring is installed until the top layer of concrete protection round blocks 2 is higher than the pre-filled earth and stone height by 1M-1.5M; concrete is poured into the damping cylindrical barrel 4;

[0062] In this embodiment, four buffer arcs 6 are positioned around the second layer of concrete protective circular blocks 2. The connecting block 1005 and stop plate 1006 on each buffer arc 6 are installed in a T-shaped chute 8. Adjacent buffer arcs 6 are connected by a sliding connection shaft 1010 to form a circular ring structure that protects the outer surface of the concrete protective circular blocks 2. Each buffer arc 6 is connected to a hoist mounted on the top of the lighting tower 1 via a suspension rope 7. Earth and rock are then filled around the concrete protective circular blocks 2 where the buffer arcs 6 are located. Once the area around one layer of concrete protective circular blocks 2 is completely filled with earth and rock, the hoist hoists all the buffer arcs 6 to the next layer of concrete protective circular blocks 2. The circular ring structure formed by multiple buffer arcs 6 changes in size according to the outer diameter of the concrete protective circular blocks 2, protecting the outer surface of the corresponding layer of concrete protective circular blocks 2. Earth and rock continue to fill the area around the corresponding layer of concrete protective circular blocks 2 until the earth and rock fill reaches the desired height. With sufficient equipment, earth and rock filling can be performed simultaneously around multiple lighting towers 1.

[0063] After the initial earthwork filling is completed, the main construction work in this stage is to fill the remaining earthwork within the easily broken pole range above the tower platform and set up temporary lights: (1) After the earthwork filling above the lighting tower 1 is completed, apply to the relevant airport department to adjust the airport's main landing direction or apply for suspension of flights, and carry out protective removal of the lights and easily broken parts in the filling area. After the lights are removed, earthwork construction is carried out in accordance with relevant design requirements and construction specifications, and the earthwork within the lighthouse range is filled to the design elevation. After the filling is completed, considering the later extension section pavement structure and anti-blowing pad construction, the removed lights are made into a movable simple light row and installed in the original position for use as temporary lights. The light row structure is required to be stable and anti-overturning. After meeting the navigation conditions, it is opened to navigation.

[0064] (2) After the earthwork construction is completed, the simple light bar can be moved to a safe location outside the construction area when the next stage of construction begins. After each construction is completed, the light bar will be moved back to its original location. The simple light bar will be removed after the new approach lights and sequential flashing lights are put into use.

[0065] The protective device for the visual navigation light tower of the present invention saves a lot of construction time for airport expansion and minimizes the impact on the normal passage of flights.

[0066] The present invention provides a protective device for a visual navigation light tower, which adopts three protective measures. The first protective measure is: multiple layers of concrete protective round blocks 2 are poured from the bottom to the top of the light tower 1. The concrete protective round blocks 2 are integrated with the light tower 1 to form a "steel plate concrete" structure, which greatly improves the structural strength of the light tower 1; the second protective measure is: a damping cylindrical barrel 4 is set in the light tower 1, and the damping cylindrical barrel 4 is filled with concrete. According to the design principle of the damper structure, when the landfilled earth and stone forms a strong impact on the light tower 1, the damping cylindrical barrel 4 is used to The resistance force reduces the swing of the lighting tower 1, thereby effectively preventing the lighting tower 1 from tilting or deformation due to impact; the third protection measure: a plurality of buffer arc blocks 6 are arranged around the concrete protection circle 2, and the adjacent buffer arc blocks 6 are movably connected to form a circular ring structure to protect the outer ring surface of the concrete protection circle 2. When the area where the lighting tower 1 is set is filled with earth and stone, the earth and stone are first squeezed on the buffer arc block 6. Through the buffering effect of the buffer arc block 6, the impact force of some earth and stone is effectively eliminated, thereby reducing the impact on the lighting tower 1.

[0067] Example 2

[0068] like Figures 1-13 As shown, the present invention is a protective device for a visual navigation light tower, based on the above embodiment, as Figure 5As shown, T-shaped chutes 8 are provided longitudinally along the annular surface of the concrete protection round block 2, corresponding to each buffer arc block 6. The T-shaped chutes 8 between two adjacent layers of concrete protection round blocks 2 provide a smooth transition. The T-shaped chutes 8 can be directly cast into the concrete protection round blocks 2 using a mold structure, or they can be cast using a mold structure and then removed. In actual use, a mold structure made of steel plate is often used to cast the T-shaped chutes 8 into the concrete protection round blocks 2.

[0069] Example 3

[0070] like Figures 1-13 The present invention illustrates a protective device for a navigational light tower. Based on the aforementioned embodiment, a set of fixed pulleys 9 are installed at the top of the lighting tower 1, corresponding to each buffer arc 6. The hoisting ropes 7 pass through these fixed pulleys 9 and connect to a winch. As shown in the accompanying drawings, four corresponding buffer arcs 6 pull four hoisting ropes 7 through the fixed pulleys 9, then connect to the rollers of the winch, simultaneously lifting the four buffer arcs 6. The winch is fixedly mounted on the top of the lighting tower 1 and remotely controlled.

[0071] Example 4

[0072] like Figures 1-13 As shown, the present invention is a protective device for a visual navigation light tower, based on the above embodiment, as Figure 13 As shown, the damping cylindrical barrel 4 is spliced inside the lighting tower 1, and multiple spring hooks are welded around the outside of the damping cylindrical barrel 4. One end of the damping spring is hooked on the spring hook, and the other end is connected to the corresponding concrete protection block 2. When a connecting reinforcement layer is provided in the lighting tower 1, the damping cylindrical barrel 4 is divided into multiple sections, and a section of damping cylindrical barrel 4 is provided between the two layers of connecting reinforcement layers. The two adjacent sections of damping cylindrical barrel 4 are connected by cables. After the concrete protection block 2 is poured around a section of the damping cylindrical barrel 4, the concrete is poured into the section of the damping cylindrical barrel 4.

[0073] Example 5

[0074] like Figures 1-13 As shown, the present invention is a protective device for a visual navigation light tower, based on the above embodiment, as Figures 6-10As shown, the buffer arc block 6 includes an inner arc plate frame 10, an outer arc plate frame 11, and an end arc plate frame 12. The inner arc opening of the outer arc plate frame 11 is movably fastened to the outer arc opening of the inner arc plate frame 10. The inner arc plate frame 10 is provided with one or more supporting connecting shafts 13 that pass through the outer arc plate frame 11. The outer ends of the supporting connecting shafts 13 are fixed by nuts. A buffer spring 14 is sleeved on the supporting connecting shafts 13 between the outer arc plate frame 11 and the inner arc plate frame 10. The end arc plate frame 12 is movably fastened to the ends of the outer arc plate frame 11, and a tensioning spring 1206 is provided between the end of the end arc plate frame 12 and the end of the outer arc plate frame 11. When earth and rock are filled around the buffer arc block 6, the earth and rock are first pressed against the outer arc plate frame 11 or the end arc plate frame 12. The elastic force of the buffer spring 14 acts as a buffer. The compression of the buffer spring 14 reduces the impact force between the earth and rock on the lighting tower 1.

[0075] The inner arc plate frame 10 comprises an upper inner arc plate 1001, a lower inner arc plate 1002, an inner arc end plate 1003 and an inner arc vertical plate 1004. The upper inner arc plate 1001 and the lower inner arc plate 1002 are provided on the upper and lower end surfaces of the inner arc vertical plate 1004 respectively. The upper inner arc plate 1001, the lower inner arc plate 1002 and the inner arc vertical plate 1004 are sealed and connected by the inner arc end plate 1003. The inner arc end plate 1003 can improve the structural strength of the inner arc plate frame 10 and can also prevent earth and stone from moving. Entering the interior of the buffer arc block 6, a connecting block 1005 is provided in the middle of the inner arc surface of the inner arc vertical plate 1004, and a limiting plate 1006 is hinged on the connecting block 1005. The connecting block 1005 and the limiting plate 1006 are limitedly installed in the T-shaped slide groove 8. The connecting block 1005 and the limiting plate 1006 are hinged, so that it is convenient for the limiting plate 1006 to slide from one T-shaped slide groove 8 into another T-shaped slide groove 8. A supporting connecting shaft 13 is provided in the middle of the outer arc surface of the inner arc vertical plate 1004.

[0076] The outer arc plate frame 11 resembles a U-shaped structure and comprises an outer arc upright plate 1101, an upper outer arc plate 1102, and a lower outer arc plate 1103. The upper and lower outer arc plates 1102 and 1103 are positioned on the upper and lower ends of the outer arc upright plate 1101, respectively. End arc plate frame connecting plates 1104 are positioned on either side of the inner arc surface of the outer arc upright plate 1101. These connecting plates 1104 are provided with strip grooves 1105. These connecting plates 1104 connect to the end arc plate frame 12. Because the end arc plate frame 12 extends and retracts along an arc, the strip grooves 1105 are provided on these connecting plates to facilitate the flexible connection of the guide rods 1205 on the end arc plate frame 12. These grooves also serve as a position limiter for the end arc plate frame 12.

[0077] like Figure 10As shown, the end arc plate frame 12 includes an end arc stand 1201, an upper end arc plate 1202, a lower end arc plate 1203 and an end end plate 1204. The upper end arc plate 1202 and the lower end arc plate 1203 are provided on the upper and lower end surfaces of the end arc stand 1201 respectively. The outer ends of the end arc stand 1201, the upper end arc plate 1202 and the lower end arc plate 1203 are sealed and connected by the end end plate 1204. A guide rod 1205 is provided on the inner surface of the end plate 1204. A tensioning spring 1206 is sleeved on the guide rod 1205. The guide rod 1205 is movably inserted into the strip groove 1105 on the end arc plate frame connecting plate 1104. A stop block is provided on the inner surface of the upper end arc plate 1202, blocking the front end of the upper outer arc plate 1102. The stop block 1207 is primarily used to retain the end arc plate frame 12 on the outer arc plate frame 11. The end arc plate frame 12 primarily functions to adjust the outer arc surface size of the buffer arc block 6 according to the different outer diameters of the concrete protection circular blocks 2. In addition, when earth and rock compress the outer arc surface of the buffer arc block 6, the outer arc surface (including the end arc plate 1201 and the outer arc plate 1101) will first move toward the center of the circle. Without the end arc plate frame 12, the outer arc surface would be immobile.

[0078] A hanging block 1007 is provided on the upper inner arc plate 1001, and the hanging block 1007 is connected to the hanging rope 7. A limiting rotating shaft head 1008 is respectively provided at the two ends of the lower inner arc plate 1002. The limiting rotating shaft head 1008 can rotate freely. The limiting rotating shaft head 1008 is provided with a rotating shaft head connecting hole 1009. On the two adjacent limiting rotating shaft heads 1008 on the adjacent buffer arc blocks 6, a sliding connecting shaft 1010 is movably inserted into the rotating shaft head connecting hole 1009 of the two limiting rotating shaft heads 1008.

[0079] The sliding connecting shaft 1010 can also move freely in the shaft head connecting hole 1009. In order to make the connection between the two buffer arc blocks 6 more firmly, a spring is provided on the sliding connecting shaft 1010 outside the shaft head connecting hole 1009. In this way, the two buffer arc blocks 6 are fitted more closely by squeezing the elastic force.

[0080] like Figure 11-12 As shown, the adjacent buffer arc blocks 6 are movably connected to form a circular structure to protect the outer ring surface of the concrete protection circle block 2. Since the outer diameter of each layer of concrete protection circle block 2 decreases from bottom to top, the multiple buffer arc blocks 6 arranged around it also need to follow the diameter change, otherwise they will not be able to protect the lighting tower 1; in addition, the buffer arc block 6 also needs to be relatively airtight, otherwise it will be affected by soil or stones and lose its buffering effect.

[0081] The present invention designs the buffer arc block 6 into three parts: an inner arc plate frame 10, an outer arc plate frame 11 and an end arc plate frame 12. The outer arc plate frame 11 can achieve buffering expansion and contraction relative to the inner arc plate frame 10, and the end arc plate frame 12 is connected and expanded relative to the inner arc plate frame 10 and the outer arc plate frame 11 at both ends, which can meet the diameter change requirement. At the same time, the outer arc plate frame 11 is snapped onto the outside of the inner arc plate frame 10, and the end arc plate frame 12 is snapped onto the inner arc plate frame 10 and the outer arc plate frame 11 at both ends. This can not only ensure the buffering effect, but also prevent the buffer arc block 6 from being interfered with.

[0082] Example 6

[0083] like Figures 1-13 As shown, a method for protecting a visual navigation light tower includes the following steps:

[0084] Step 1: Move the cables on the lighting tower 1 in the earth-filled area to the top of the tower, clean up the debris at the bottom of the lighting tower 1, and prepare for the protection construction of the lighting tower 1;

[0085] Step 2: assemble the damping cylindrical barrel 4 inside the lighting tower 1, and then connect it to the top of the lighting tower 1 through the cable 5 for suspension;

[0086] Step 3: Starting from the bottom of the lighting tower 1, a casting mold for the first layer of concrete protection round blocks 2 is set up. The casting mold includes an outer ring mold, a T-shaped slide mold is set on the outer ring mold, and a damping circular hole mold for casting the concrete protection round blocks 2. Multiple damping spring connectors connected to the concrete protection round blocks 2 are preset through the damping circular hole mold;

[0087] Step 4: After the casting mold is set up, concrete is poured into the casting mold to form a layer of concrete protective round block 2;

[0088] Step 5: After the concrete protective round block 2 is solidified, the casting mold is removed, and the damping cylinder barrel 4 is connected to the damping spring connector on the concrete protective round block 2 using a damping spring;

[0089] Step 6: Setting up a casting mold for casting the next layer of concrete protection round blocks 2 on the cast concrete protection round blocks 2;

[0090] Step 7: Repeat the steps of setting up the casting mold for the concrete protection round block 2, casting the concrete protection round block 2 in the casting mold, and installing the damping spring until the top layer of the cast concrete protection round block 2 is 1M-1.5M higher than the height of the pre-filled earth and rock.

[0091] Step 8: pouring concrete into the damping cylindrical barrel 4;

[0092] Step 9: Multiple buffer arc blocks 6 are arranged around the first or second layer of concrete protection circular blocks 2. The connecting block 1005 and the limiting plate 1006 of each buffer arc block 6 are installed in the T-shaped chute 8. Adjacent buffer arc blocks 6 are connected by sliding connecting shafts 1010 to form a circular structure to protect the outer surface of the concrete protection circular block 2. Each buffer arc block 6 is connected to the winch installed at the top of the lighting tower 1 via a suspension rope 7.

[0093] Step 10: Fill earth and stone around the concrete protection round block 2 with the buffer arc block 6. When the area around one layer of concrete protection round block 2 is filled with earth and stone, lift all the buffer arc blocks 6 to the position of the next layer of concrete protection round block 2 by a winch. Multiple buffer arc blocks 6 are connected to form a circular structure that changes according to the outer diameter of the concrete protection round block 2, protecting the outer ring surface of the concrete protection round block 2 of this layer, and continue to fill earth and stone around the concrete protection round block 2 of this layer until the earth and stone are filled to the set height.

[0094] The present invention provides a method for protecting a visual navigation light tower, which adopts three protective measures. The first protective measure is: multiple layers of concrete protective round blocks 2 are poured on the light tower 1 from the bottom to the top. The concrete protective round blocks 2 are integrated with the light tower 1 to form a "steel plate concrete" structure, which greatly improves the structural strength of the light tower 1; the second protective measure is: a damping cylindrical barrel 4 is set in the light tower 1, and the damping cylindrical barrel 4 is filled with concrete. According to the design principle of the damper structure, when the landfill earth and stone forms a strong impact on the light tower 1, the damping cylindrical barrel 4 is used to The resistance force reduces the swing of the lighting tower 1, thereby effectively preventing the lighting tower 1 from tilting or deformation due to impact; the third protection measure: a plurality of buffer arc blocks 6 are arranged around the concrete protection circle 2. Adjacent buffer arc blocks 6 are movably connected to form a ring structure to protect the outer surface of the concrete protection circle 2. When the area where the lighting tower 1 is set is filled with earth and stone, the earth and stone are first squeezed on the buffer arc blocks 6. The buffering effect of the buffer arc blocks 6 effectively eliminates some of the impact force of the earth and stone, thereby reducing the impact on the lighting tower 1;

[0095] The adjacent buffer arc blocks 6 are movably connected to form a ring structure to protect the outer ring surface of the concrete protection circle block 2. Since the outer diameter of each layer of concrete protection circle block 2 decreases from bottom to top, the multiple buffer arc blocks 6 arranged around it also need to follow the diameter change, otherwise they will not be able to protect the lighting tower 1. In addition, the buffer arc blocks 6 need to be relatively airtight, otherwise they will be affected by soil or stones and lose their buffering effect.

[0096] The present invention designs the buffer arc block 6 into three parts: an inner arc plate frame 10, an outer arc plate frame 11 and an end arc plate frame 12. The outer arc plate frame 11 can achieve buffering expansion and contraction relative to the inner arc plate frame 10, and the end arc plate frame 12 is connected and expanded relative to the inner arc plate frame 10 and the outer arc plate frame 11 at both ends, which can meet the diameter change requirement. At the same time, the outer arc plate frame 11 is snapped onto the outside of the inner arc plate frame 10, and the end arc plate frame 12 is snapped onto the inner arc plate frame 10 and the outer arc plate frame 11 at both ends. This can not only ensure the buffering effect, but also prevent the buffer arc block 6 from being interfered with.

[0097] After the initial earthwork filling is completed, the main construction work in this phase is to fill the remaining earthwork within the easily broken pole range above the tower platform and set up temporary lights: (1) After the earthwork filling above the lighting tower 1 is completed, apply to the relevant airport department to adjust the airport's main landing direction or apply for suspension of flights, and carry out protective removal of the lights and easily broken parts in the filling area. After the lights are removed, earthwork construction is carried out in accordance with relevant design requirements and construction specifications, and the earthwork within the lighthouse range is filled to the design elevation. After the filling is completed, considering the later extension section pavement structure and the construction of the anti-blowing pad, the removed lights are made into a movable simple light bar and installed in the original position for temporary lighting. The light bar structure is required to be stable and anti-overturning. After the navigation conditions are met, it can be opened to navigation. (2) After the earthwork construction is completed, the simple light bar can be moved to a safe location outside the construction area at the beginning of the next phase of construction, and the light bar is moved back to its original position after each construction is completed. The simple light bar is removed after the new approach lights and sequential flashing lights are put into use.

[0098] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
