[0018] Beneficial effects of this application

[0019] The standard section design enables the tower structure to effectively resist the effects of external loads such as wind pressure and snow pressure, improving the stability of the entire tower structure. At the same time, the standardized design of the standard section makes the installation process simpler and faster, reducing installation costs and time.

[0020] By installing a straight ladder on one side of the watchtower, the ladder can be better integrated with the tower structure, reducing obstruction of the observation view and improving the observation effect. The design of the straight ladder reduces detours and turns during the climbing process, saving the physical strength and time of the duty personnel.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0043] This application proposes a watchtower with a straight ladder, such as Figures 1 to 10As shown, it includes: a tower structure 100, a platform 300, a guardhouse 600, and a straight ladder 200; the platform 300 is located on top of the tower structure 100, the guardhouse 600 is located on the top surface of the platform 300, and the platform 300 has an access opening 510; the straight ladder 200 is located on one side of the tower structure 100, one end of the straight ladder 200 is suitable for contacting the installation ground, and the other end of the straight ladder 200 is connected to the access opening 510; and the length direction of the straight ladder 200 is parallel to the length direction of the tower structure 100, and two [unclear text - possibly related to ladder 200] are provided on one side of the straight ladder 200. The above-mentioned protective cages 230, two or more protective cages 230 are arranged sequentially along the length of the straight ladder 200; the tower structure 100 includes two or more standard sections and connectors 130, the two or more standard sections are connected sequentially by connectors 130; the standard section includes: four columns 110 and two or more diagonal braces 120; the four columns 110 are arranged opposite each other in pairs, and two or more diagonal braces 120 are provided between any two adjacent columns 110; the four columns 110 of any standard section are fixedly connected to the four columns 110 of the adjacent standard sections above and below by connectors 130.

[0044] It should be noted that the tower structure 100 bears the weight of the entire structure and external loads, providing stable support for the platform 300 and the guardhouse 600. The platform 300, located at the top of the tower structure 100, provides a spacious working area for personnel, enabling them to easily conduct observation and monitoring. The guardhouse 600 is fixedly installed on the top surface of the platform 300, providing a relatively comfortable indoor space for personnel to remain on duty for extended periods, continuously observing the surrounding area. The straight ladder 200 is located on one side of the tower structure 100, providing personnel with a clear and easily identifiable climbing path. This arrangement makes the climbing process more convenient. For enhanced intuitiveness and safety, the design of one end of the straight ladder 200 contacting the installation ground ensures its firm fixation, preventing swaying and tilting during climbing and guaranteeing its stability and safety. The access opening 510 provides a convenient passage for personnel on duty, allowing them to easily access the platform 300 or the duty booth 600 via the straight ladder 200. The parallel arrangement of the length of the straight ladder 200 with that of the tower structure 100 helps maintain consistency and coordination between the two structures. This parallel arrangement also makes the straight ladder 200 more stable during climbing.

[0045] like Figures 1 to 8As shown, the safety cage 230 is fixedly connected to the straight ladder 200, and the straight ladder 200 is suspended at the access opening 510 of the platform 300. The on-duty personnel ascend the straight ladder 200 from the bottom safety cage 230, pass through the access opening 510 of the platform 300, and work on the duty platform 300. The safety cage 230 provides a safe barrier for the on-duty personnel when climbing the straight ladder 200, preventing the on-duty personnel from falling due to slips or accidents, and ensuring the safety of the straight ladder 200 during use.

[0046] By installing a straight ladder 200 on one side of the watchtower, the ladder 200 can be better integrated with the tower structure 100, reducing obstruction of the observation view and improving the observation effect. Compared with the existing inclined ladder, the design of the straight ladder 200 reduces the detours and turns during the climbing process, saving the physical strength and time of the duty personnel. At the same time, the structure of the straight ladder 200 is relatively simple, making installation and maintenance more convenient, and reducing the overall construction and operation costs of the watchtower.

[0047] like Figure 4 As shown, the four columns 110 are parallel to each other along their length. Diagonal braces 120 are intersecting between any two adjacent columns 110, and both ends of the diagonal braces 120 are fixedly connected to the ends of the columns 110 via connectors 130. The two adjacent columns 110 and the intersecting diagonal braces 120 together form a triangular support structure. The design of the diagonal braces 120 significantly enhances the stability of the standard section. When subjected to large loads, the diagonal braces 120 can share part of the load, reducing the burden on the columns 110 and improving the load-bearing capacity of the standard section. Figures 1 to 3 As shown, the four columns 110 of any standard section are fixedly connected to the four columns 110 of the adjacent standard sections above and below through connectors 130, thereby forming a stable and continuous support structure. This allows the tower structure 100 to effectively resist the influence of external loads such as wind pressure and snow pressure, improving the stability of the entire tower structure 100. The standardized design of the standard section makes its installation process simpler and faster, reducing installation costs and time. At the same time, the standard section is also easy to disassemble and replace, providing convenience for the maintenance of the tower structure 100.

[0048] Furthermore, both the uprights 110 and the diagonal braces 120 are made of angle steel. The connector 130 is matched with the uprights 110. The uprights 110 of any standard section abut against the uprights 110 of the adjacent standard sections above and below. The connector 130 is fixedly installed at the connection of the two uprights 110 by welding. The two diagonal braces 120 that are intersected are fixedly connected to the connector 130 by high-strength bolts and self-tapping screws. The two diagonal braces 120 are located on opposite sides of the uprights 110. The intersection of the two diagonal braces 120 is fixed secondary by high-strength bolts and self-tapping screws.

[0049] Preferred, such as Figures 2 to 4 As shown, the main body of the standard section is a cube-shaped frame structure. The length of each standard section's column 110 is 2m. The four columns 110 are arranged in pairs opposite each other, and the preset distance between each pair of adjacent columns 110 is 2m.

[0050] In one possible implementation, such as Figures 1 to 3 As shown, the bottom of the standard section at the bottom is provided with a first column base plate 140, which is suitable for fixing the tower structure 100 to the installation ground.

[0051] It should be noted here that, as Figure 11 As shown, the first column base plate 140 includes a first base plate 141 and a first reinforcing plate 142. The bottoms of the four columns 110 of the standard section at the bottom are all fixedly connected to the first base plate 141. The first base plate 141 is suitable for fixing the tower structure 100 to the installation ground. The first reinforcing plate 142 is located between the top surfaces of the columns 110 and the first base plate 141, and the plane of the first reinforcing plate 142 is perpendicular to the plane of the first base plate 141. The first reinforcing plate 142 connects the first base plate 141 and the columns 110, increasing the contact area and connection points between them, and improving the connection strength and stability between the columns 110 and the first base plate 141. When the tower structure is subjected to external forces, the first reinforcing plate 142 can distribute the load it bears to the first base plate 141, ensuring that the tower structure 100 can be stably installed on the installation ground.

[0052] Furthermore, the first base plate 141, the first reinforcing plate 142, and the column 110 are fixedly connected by welding. Welding ensures a tight connection between the first base plate 141, the first reinforcing plate 142, and the column 110, thereby enhancing the strength and rigidity of the overall structure. At the same time, welding can effectively reduce on-site work and improve overall construction efficiency.

[0053] In one possible implementation, such as Figures 1 to 5 As shown, the straight ladder 200 includes a ladder hanging column 210 and two or more step bars 220; the length direction of the ladder hanging column 210 is parallel to the length direction of the upright column 110, and the two or more step bars 220 are all arranged between the ladder hanging column 210 and the upright column 110.

[0054] It should be noted that the two ends of the step bar 220 are fixedly connected to the ladder hanging post 210 and the upright post 110 by welding. The parallel design of the ladder hanging post 210 and the upright post 110 allows the load generated by the staff during climbing to be evenly transferred to the installation ground through the upright post 110 and the ladder hanging post 210, ensuring the stability of the straight ladder 200 during use. The length direction of two or more step bars 220 is perpendicular to the length direction of the ladder hanging post 210, and the two or more step bars 220 are equidistant from each other along the length direction of the ladder hanging post 210. The equidistant arrangement of the step bars 220 and their perpendicularity to the ladder hanging post 210 ensures that the user's feet can be stably placed on the step bars 220. When the climber's feet step on the step bars 220, the vertical design allows the feet to be placed naturally, allowing the climber to exert force more easily and move up or down more easily.

[0055] Furthermore, the vertical climbing ladder 200 has a 90-degree angle between its length and the horizontal plane, a width of 700mm, a step height of 200mm, and a step distance of 133mm. The 200mm step height design avoids the risk of climbers losing their balance due to lifting their legs too high. At the same time, the 133mm step distance ensures sufficient support between the feet, preventing slips caused by insufficient foot spacing. This design allows climbers to maintain stability during climbing and better control their bodies in case of emergencies, reducing the occurrence of accidents.

[0056] In one possible implementation, the main body of the cage 230 is U-shaped, the opening of the cage 230 faces the straight ladder 200, and the two ends of the opening of the cage 230 are connected to the ladder hanging post 210 and the upright post 110 respectively by fasteners.

[0057] It should be noted here that, as Figures 3 to 5 As shown, the U-shaped cage 230 provides excellent all-around protection. When personnel are climbing the straight ladder 200, their bodies are effectively protected in the front, sides, and back. The opening of the cage 230 faces the straight ladder 200, allowing personnel to easily enter and exit the cage. Both ends of the cage 230 are connected to the ladder hanging post 210 and the upright post 110 by fasteners, which can tightly integrate the cage 230 and the straight ladder 200 into a whole structure. When the straight ladder 200 is subjected to external forces (such as vibration, wind load, etc.), the cage 230 can work together with the straight ladder 200 to share the force, enhancing the stability of the overall structure.

[0058] Preferably, the fasteners can be high-strength bolts or self-tapping screws from the existing technology.

[0059] In one possible implementation, such as Figures 3 to 5 As shown, it also includes cage side posts 240, which are fixedly connected to two or more cages 230, and the length direction of the cage side posts 240 is parallel to the length direction of the ladder hanging posts 210. It should be noted that the cage side posts 240 provide additional support for the cages 230, effectively distributing the load on the cages 230 and the straight ladder 200, enhancing the stability of the overall structure. The parallel design allows the cage side posts 240 and the ladder hanging posts 210 to work together better when under stress. When the climber's weight or external force acts on the straight ladder 200 and the cages 230, the force can be more effectively transmitted to the installation ground along the parallel direction.

[0060] Furthermore, there are two or more side posts 240 of the cage, and the two or more side posts 240 can be fixedly connected to the cage 230 by welding, high-strength bolts, self-tapping screws or other methods.

[0061] In one possible implementation, platform 300 includes a platform frame and walkway 430; the main body of the platform frame has a square grid structure, and the walkway 430 is fixedly laid on the side of the platform frame away from the standard section.

[0062] It should be noted here that, as Figures 6 to 8 As shown, the platform frame with a square grid structure provides good stability. Due to the symmetry of the square grid, the force transmission is more balanced, reducing the possibility of deformation or damage to the platform frame caused by excessive local stress, and enhancing the overall load-bearing capacity of the platform 300. The walkway 430 is suitable for providing a safe and stable passage space for duty personnel and equipment. When on duty, the duty personnel can move freely around on the walkway 430 of the platform 300 to meet their work needs.

[0063] Specifically, such as Figure 7As shown, the platform frame includes four side beams 310, two main beams 320, two crossbeams 330, a first beam 340, a second beam 350, an opening secondary beam 520, and two or more struts 360. The four side beams 310 are connected end to end to form a square frame. The two main beams 320 and the two crossbeams 330 are arranged parallel to each other within the frame, and the length directions of the main beams 320 and the crossbeams 330 are perpendicular to each other. The intersections of the main beams 320 and the crossbeams 330 are connected by a main-secondary beam connecting plate 301 and fixed with high-strength bolts. The first beam 340 is located between the two main beams 320 and is connected to the two crossbeams 330 through a secondary beam connecting plate 302. The second beam 350 is fixed with high-strength bolts. It passes through one of the main beams 320 and the first beam 340 in sequence and then connects to the other main beam 320. The intersection of the second beam 350 and the main beam 320 is connected by the main-secondary beam connecting plate 301 and fixed with high-strength bolts. The intersection of the second beam 350 and the first beam 340 is connected by the secondary beam connecting plate 302 and fixed with high-strength bolts. The secondary beam 520 of the opening is located between the two cross beams 330, and there is a preset distance between the secondary beam 520 of the opening and the main beam 320 to form an access opening 510. Two or more support rods 360 are arranged crosswise inside the frame, and the length direction of the two or more support rods 360 is located on the 45-degree diagonal of the frame.

[0064] like Figure 3 , Figure 8 , Figure 12 As shown, a lower support connecting plate 410 is provided at the intersection of the main beam 320 and the cross beam 330. Correspondingly, the top of the four columns 110 of the standard section at the top of the tower structure 100 is provided with a first column top plate 150. The lower support connecting plate 410 and the first column top plate 150 are fixed with high-strength bolts, thereby fixing the platform 300 to the top of the tower structure 100.

[0065] In one possible implementation, such as Figure 6 As shown, it also includes a first fence 440; the main body of the first fence 440 is a fence frame structure with bends, and the first fence 440 is set on the platform frame and located at the access opening 510.

[0066] It should be noted that the opening of the first fence 440 faces the side of the guard booth 600; the bottom of the first fence 440 is fixedly equipped with a fence connector, and the first fence 440 is connected to the secondary beam 520 of the opening through the fence connector and is fixed with high-strength bolts. The L-shaped structure of the first fence 440 can guide personnel to enter the platform 300 through the access opening 510 correctly, while preventing the personnel on duty from accidentally falling from the access opening 510 when walking on the platform 300.

[0067] In one possible implementation, such as Figure 6 As shown, it also includes a second fence 450; the second fence 450 is set around the perimeter of the platform frame. It should be noted that there are four second fences 450, and each of the four second fences 450 is set on the four side beams 310 by fence connectors and fixed by high-strength bolts. The second fences 450 form a continuous protective boundary around the perimeter of the platform frame, thereby preventing on-duty personnel from falling from the edge of the platform 300 due to negligence, slipping, collision or other accidents when walking, working or operating equipment on the platform 300.

[0068] Preferably, the platform frame has a length and width of 4.4m, and the first fence 440 and the second fence 450 have a height of 1.05m.

[0069] In one possible implementation, the guard booth 600 includes a roof 610 and a roof 620; an upper support connecting plate 420 is provided on the platform 300, the roof 610 is fixedly connected to the platform 300 through the support connecting plate, and the roof 620 is located on top of the roof 610.

[0070] It should be noted here that, as Figure 6 , Figure 9 , Figure 10 As shown, the roof 610 includes four support columns 611 and eight angle steel crossbars 612. The four support columns 611 are arranged in pairs facing each other. Any two adjacent support columns 611 are fixedly connected by any two angle steel crossbars 612, and a sandwich insulation wall panel 613 is provided between any two adjacent support columns 611. The bottom of each of the four support columns 611 is provided with a second column base plate 6111. At the intersection of the main beam 320 and the cross beam 330, and on the side away from the lower support connecting plate 410, an upper support connecting plate 420 is fixedly provided. The second column base plate 6111 matches the upper support connecting plate 420. The second column base plate 6111 and the upper support connecting plate 420 are fixedly connected by high-strength bolts, thereby fixing the roof 610 on the platform 300. The top of each of the four support columns 611 is provided with a second column top plate 6112. The roof 620 is fixedly installed on the top of the roof 610 through the second column top plate 6112.

[0071] Furthermore, such as Figure 9 , Figure 10As shown, the roof 620 includes top angle steel crossbars 621, square tube folded beams 622, square tube beams 623, C-shaped steel roof purlins 624, C-shaped steel struts 625, and sandwich insulated roof panels 626. The C-shaped steel roof purlins 624 form a rectangular frame structure. The square tube folded beams 622 and square tube beams 623 are intersected within the frame structure formed by the C-shaped steel roof purlins 624. The top angle steel crossbars 621 are set within the square tube... Between the folded beam 622 and the square tube beam 623, and with both ends of the top angle steel crossbar 621 fixedly connected to the square tube folded beam 622 and the square tube beam 623 respectively, C-shaped steel struts 625 are set between the C-shaped steel roof purlins 624 and the top angle steel crossbar 621, and the length direction of the C-shaped steel struts 625 is perpendicular to the length direction of the top angle steel crossbar 621. The sandwich insulated roof panel 626 is laid on the roof 620.

[0072] Preferably, the main body of the roof 610 has a cuboid structure of 2m*2m*2.37m.

[0073] Furthermore, an entrance door 614 is provided on one side of the building 610 for opening or closing the building 610. The entrance door 614 can be opened and closed flexibly and can be adjusted in a timely manner according to actual work needs, effectively ensuring that the duty personnel can conveniently enter and exit the duty booth 600 while performing tasks on the watchtower, while also maintaining the necessary enclosure and security of the duty area. A sliding window 615 is provided on the building 610, which is located on the side of the building 610 adjacent to the entrance door 614. The design of the sliding window 615 allows the window sash to move left and right, increasing indoor and outdoor air circulation and improving the indoor environment.
