[0024] The following will make a specific and detailed description of the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0025] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a new type of portable and easy-to-install distribution network pole foundation steel mold includes two first U-shaped steels 1 arranged in parallel and spaced relation, two second U-shaped steels 2 arranged in parallel and spaced relation are arranged at both ends of the first U-shaped steel 1, and a locking mechanism 3 is arranged between each first U-shaped steel 1 and each second U-shaped steel 2, so that the backs of the two first U-shaped steels 1 and the two second U-shaped steels 2 are spliced ​​together to form a square steel mold for fixing the distribution network pole foundation. Specifically, a portable and easy-to-install distribution network pole foundation steel mold fully considers the convenience of on-site construction, structural stability and high efficiency of repeated use. The installation process is simplified, the construction efficiency is improved, and the stability of the distribution network pole foundation is ensured. The first U-shaped steel 1 is the main load-bearing and supporting structure of the steel mold. The first U-shaped steel 1 is made of high-strength alloy steel and is precisely processed to ensure that it remains stable when subjected to soil pressure and the weight of the pole. Its unique U-shaped design not only increases the structural strength, but also facilitates assembly and disassembly with other components. The second U-shaped steel 2 is located at both ends of the first U-shaped steel 1, forming a vertical cross frame structure, which further enhances the overall rigidity and stability of the steel mold. The second U-shaped steel 2 is also made of high-quality steel and connected to the first U-shaped steel 1 to ensure the firmness and reliability of the connection. The locking mechanism 3 is the key to the rapid installation and disassembly of the steel mold. The locking mechanism 3 is set at the junction of the first U-shaped steel 1 and the second U-shaped steel 2, and adopts a quick locking technology (such as a spring lock, a rotating buckle, etc.), which can achieve rapid locking and unlocking without complicated tools. It not only simplifies the installation process, but also improves construction efficiency and reduces labor costs. All components of the steel mold are designed as a detachable structure, which is convenient for transportation, storage and recycling, conforms to modern environmental protection concepts, and reduces resource waste. Under the premise of ensuring structural strength, lightweight materials are used as much as possible to reduce the overall weight, facilitate manual handling and installation, and reduce energy consumption during transportation. This new type of portable and easy-to-install distribution network pole foundation steel mold not only solves many problems in traditional pole foundation construction, but also greatly improves construction efficiency and quality, providing strong support for the construction of power infrastructure.

[0026] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the locking mechanism 3 includes panel latches 31 provided at both front ends of the first U-shaped steel 1, and fixing hooks 32 matching the panel latches 31 are provided at both back ends of the second U-shaped steel 2. Specifically, the locking mechanism 3, as a key component in the entire portable and easily installable distribution network pole foundation steel formwork, ensures the stability and safety of the steel formwork structure. The locking mechanism 3 mainly consists of two parts: the panel latch 31 and the fixing hook 32. These two parts cooperate with each other to achieve quick locking and unlocking between the first U-shaped steel 1 and the second U-shaped steel 2. The panel latches 31 are provided at both front ends of the first U-shaped steel 1, which is convenient for construction workers to operate and can ensure the stability during locking. The panel latches 31 are usually designed with a rotatable or slidable structure to easily achieve the conversion between locking and unlocking. The inside of the panel latch 31 may contain elements such as a spring mechanism or a locking pin, which are used to automatically lock when rotated or slid into place to prevent accidental loosening. Its outside may be equipped with an operating handle or button, so that construction workers can operate with one hand and improve work efficiency. The fixing hooks 32 correspond to the panel latches 31 and are provided at both back ends of the second U-shaped steel 2. The fixing hooks 32 are designed to be both strong and durable, capable of withstanding the pulling force from the first U-shaped steel 1 to ensure that the steel formwork will not loosen or deform due to external forces during use. The shape, size and position of the fixing hooks 32 are accurately calculated and designed to ensure that they can perfectly match the panel latches 31. When the panel latches 31 are rotated or slid into place, they will firmly latch onto the fixing hooks 32 to form a firm locking structure. During the installation process, construction workers first place the first U-shaped steel 1 and the second U-shaped steel 2 in the predetermined positions. Then, by operating the handle or button of the panel latch 31, rotate or slide it to a position matching the fixing hook 32. At this time, the locking mechanism inside the panel latch 31 will be automatically activated to firmly lock the first U-shaped steel 1 onto the second U-shaped steel 2. The whole process does not require complex tools or additional operating steps, and is both fast and simple.

[0027] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 6As shown in the figure, the railing buckle lock 31 includes a mounting base 311 provided on the front surface of the first U-shaped steel 1. A connecting hook 312 is installed inside the mounting base 311, and a connecting arm 313 is rotatably connected to the bottom of the connecting hook 312. Specifically, the railing buckle lock 31 is one of the core components of the locking mechanism 3, which is convenient to operate, has a stable structure and is durable. The mounting base 311 is provided on the front surface of the first U-shaped steel 1 and serves as the support base for the connecting hook 312 and the connecting arm 313. It is firmly connected to the first U-shaped steel 1 to ensure that there is no displacement or loosening during the locking process. The mounting base 311 is usually made of high-strength and corrosion-resistant metal materials such as stainless steel or alloy steel. The internal structure of the mounting base 311 needs to be precisely designed to ensure that the connecting hook 312 and the connecting arm 313 can be smoothly installed and rotated. The connecting hook 312 is a key component of the railing buckle lock 31 and is responsible for matching and tightly connecting with the fixed hook 32 on the back surface of the second U-shaped steel 2 during the locking process. The shape and size of the connecting hook 312 need to correspond to those of the fixed hook 32 to ensure that the two can be smoothly docked and locked. The bottom of the connecting hook 312 is connected to the connecting arm 313 through a rotating mechanism such as a bearing or a pin shaft. The connecting hook 312 can rotate freely within a certain angle range, which is convenient for docking and locking with the fixed hook 32. The connecting arm 313 is a bridge between the connecting hook 312 and the operator. One end of it is rotatably connected to the bottom of the connecting hook 312, and the other end may be equipped with components such as an operating handle, a button or a lever, so that the construction personnel can easily rotate the connecting hook 312. The design of the connecting arm 313 needs to consider the ergonomic principle to enable the operator to hold and operate comfortably. At the same time, its length and shape need to be reasonably designed to ensure that enough torque can be generated when rotating the connecting hook 312, so as to successfully achieve locking and unlocking. During the locking process, the construction personnel first operate the handle of the connecting arm 313 to rotate the connecting hook 312 to a position matching the fixed hook 32. Then, gently push the connecting hook 312 into the fixed hook 32 and continue to rotate the connecting arm 313 until the connecting hook 312 is tightly locked with the fixed hook 32. At this time, the first U-shaped steel 1 and the second U-shaped steel 2 are firmly connected together through the railing buckle lock 31 to form a stable steel form structure.

[0028] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the connecting hook 312 includes a sliding block 3121 installed inside the mounting seat 311, a ring hook 3122 penetrating the top of the mounting seat 311 is arranged on the top of the sliding block 3121, a spring member 3123 is sleeved on the ring hook 3122 between the sliding block 3121 and the mounting seat 311, and the ring hook 3122 is connected with the fixed hook 32. Specifically, the connecting hook 312, as a key component of the fence buckle 31, ensures the stability of the steel mold structure and the convenience of operation. The sliding block 3121 is installed inside the mounting seat 311 as a support and driving component of the ring hook 3122. The ring hook 3122 is the core component of the connecting hook 312, and its shape is designed to be ring-shaped or hook-shaped so as to match and be tightly connected with the fixed hook 32. The top of the ring hook 3122 penetrates the top of the mounting seat 311, and a sufficient length is exposed to contact and lock with the fixed hook 32. The spring member 3123 is sleeved between the ring hook 3122 and the mounting seat 311, and its function is to provide elastic force so that the ring hook 3122 can maintain a certain initial position or state when no external force is applied. When the ring hook 3122 contacts the fixed hook 32 and is subjected to pressure, the spring member 3123 will be compressed and store energy; once the pressure disappears, the spring member 3123 will release energy and push the ring hook 3122 to reset. During the locking process, when the first U-shaped steel 1 and the second U-shaped steel 2 are close, the fixed hook 32 will contact the bottom of the ring hook 3122 and apply pressure. At this time, the spring member 3123 is compressed and stores energy, and at the same time, the sliding block 3121 slides along the inside of the mounting seat 311 under pressure, so that the ring hook 3122 moves upward until it is fully matched with the fixed hook 32 and locked. When unlocking is required, the construction personnel can overcome the elastic force of the spring member 3123 by operating the connecting arm 313 or other unlocking mechanisms, so that the ring hook 3122 moves downward and escapes from the locked state of the fixed hook 32.

[0029] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, during the process of splicing the backs of the two first U-shaped steel bars 1 and the two second U-shaped steel bars 2 together to form a square steel mold for fixing the distribution network pole foundation, the fixing hooks 32 provided at both ends of the back of the second U-shaped steel bar 2 will contact the two ends of the front of the first U-shaped steel bar 1. Specifically, during the process of splicing the backs of the two first U-shaped steel bars 1 and the two second U-shaped steel bars 2 together to form a square steel mold for fixing the distribution network pole foundation, when the two first U-shaped steel bars 1 are placed parallel and spaced apart and are ready to be spliced with the two second U-shaped steel bars 2, a crucial step is to ensure their precise alignment and contact. During this process, the fixing hooks 32 provided at both ends of the back of the second U-shaped steel bar 2 will first contact the two ends of the front of the first U-shaped steel bar 1. This contact is not only for physical connection but also a prerequisite for the subsequent smooth operation of the locking mechanism 3. After the contact, as the splicing process continues, the second U-shaped steel bar 2 may slide or adjust slightly along the guiding surface of the first U-shaped steel bar 1 to ensure that the fixing hook 32 and the connecting hook 312 (located in the mounting seat 311 on the front of the first U-shaped steel bar 1) reach the optimal docking position. This sliding adjustment is usually necessary because it is difficult to achieve perfect alignment in one go during actual operation. Once the fixing hook 32 and the connecting hook 312 reach the ideal docking position, the locking mechanism 3 begins to function. At this time, the construction worker will operate the connecting arm 313 or other unlocking mechanisms to make the sliding block 3121 inside the connecting hook 312 move upward under the elastic force of the spring member 3123 until the ring hook 3122 completely fits over and locks onto the fixing hook 32. This locking process is rapid and firm, ensuring that an inseparable whole is formed between the first U-shaped steel bar 1 and the second U-shaped steel bar 2. With the sequential locking of all the locking mechanisms 3, the two first U-shaped steel bars 1 and the two second U-shaped steel bars 2 form a complete square steel mold through the splicing of their backs. This steel mold is not only structurally stable and dimensionally precise but also can effectively fix the distribution network pole foundation, providing a solid support for subsequent concrete pouring and installation of electrical facilities.

[0030] Combined with Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the second U-shaped steel 2 is an integral whole. Specifically, the second U-shaped steel 2, as an integral whole, demonstrates the superiority of its structural integrity and functionality. The second U-shaped steel 2 adopts an integral molding manufacturing process to ensure its structural integrity and strength. Compared with a structure assembled from multiple components, the integrally designed second U-shaped steel 2 can better maintain shape stability when stressed, reducing potential safety hazards caused by loose or broken connections between components. In addition, the integral design simplifies the manufacturing and installation processes, improving production efficiency and construction speed. As an integral whole, parameters such as the cross-sectional shape, size, and wall thickness of the second U-shaped steel 2 are carefully designed and optimized to meet the requirements of specific application scenarios. For example, in the fixation of the distribution network pole foundation, the cross-sectional shape and size of the second U-shaped steel 2 may be customized according to the size, weight, and stress conditions of the pole to ensure that it can stably support the pole and withstand various external forces. At the same time, the integrally designed second U-shaped steel 2 is also convenient for connecting and splicing with the first U-shaped steel 1 and other components to form a stable square steel form structure. The integrally designed second U-shaped steel 2 also has certain advantages in the processing and manufacturing process. Since there is no need for the assembly and welding of multiple components, the processing procedures and manufacturing costs can be reduced. At the same time, the integral molding manufacturing process also reduces the possibility of welding defects and stress concentration, improving the overall quality and reliability of the product. In addition, with the development of modern manufacturing technologies, such as the application of cold bending forming and hot rolling forming processes, the processing accuracy and surface quality of the integrally designed second U-shaped steel 2 have also been significantly improved.

[0031] Combined with Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the second U-shaped steel 2 is formed by splicing a number of identical third U-shaped steels 6 side by side into a whole. Specifically, the second U-shaped steel 2 is an integral structure formed by splicing a number of exactly the same third U-shaped steels 6 side by side tightly. This design not only retains the excellent mechanical properties of the U-shaped steel, but also achieves greater flexibility and adaptability through modular splicing. The third U-shaped steel 6, as the basic unit constituting the second U-shaped steel 2, has standardized dimensions, shapes, and performance parameters. This modular design makes the manufacturing process of the second U-shaped steel 2 more efficient and controllable. The manufacturer can flexibly adjust the quantity and arrangement of the third U-shaped steels 6 according to actual needs to meet the requirements of distribution network pole foundations of different specifications and sizes. At the same time, the modular design is also convenient for subsequent maintenance and replacement. When a certain third U-shaped steel 6 is damaged or needs to be replaced, only the individual one needs to be replaced, without the need for overall replacement, greatly reducing the maintenance cost and time. The second U-shaped steel 2 formed by splicing a number of third U-shaped steels 6 side by side shows many advantages in performance. First of all, its overall strength and stiffness have been significantly improved, and it can better bear the weight of the distribution network pole and external loads. Secondly, due to the strengthening measures adopted at the splicing joints, the second U-shaped steel 2 can still maintain a stable structural form when subjected to complex force systems such as bending and shear. In addition, the modular design also makes the second U-shaped steel 2 have better adaptability and adjustability, and can be adjusted and optimized according to the actual site conditions and construction requirements. This second U-shaped steel 2 formed by splicing the third U-shaped steels 6 side by side has a wide range of application prospects in the fields of distribution network pole foundations, bridge bearings, building structure supports, etc. Especially in the distribution network pole foundation, the stability and bearing capacity of the second U-shaped steel 2 are crucial for ensuring the safe operation of the power grid. Through reasonable splicing methods and strengthening measures, it can be ensured that the second U-shaped steel 2 can still maintain stable performance under harsh environmental conditions, providing a strong guarantee for the safe and stable operation of the power grid.

[0032] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, fixed blocks 61 are provided on both sides of the front of all the third U-shaped steels 6. Threaded holes 62 are provided on the fixed blocks 61. The two third U-shaped steels 6 can be fixedly connected through fixing bolts 63 to form a whole. Specifically, fixed blocks 61 are provided on both sides of the front of the third U-shaped steel 6, enhancing the stability and reliability of the connection between the third U-shaped steels 6. As a connecting component, the fixed block 61 not only plays a role in positioning and supporting, but also provides a convenient interface for subsequent fixing operations. The fixed block 61 is usually made of the same or similar material as the third U-shaped steel 6 to ensure that it can work together with the U-shaped steel under stress and jointly bear the external load. On the fixed block 61, threaded holes 62 are specially provided. The positions, depths and pitches of these threaded holes 62 are carefully designed to match the size and installation requirements of the fixing bolts 63. The threaded holes 62 are the key components for connecting the third U-shaped steels 6, providing a stable installation base for the fixing bolts 63. When two third U-shaped steels 6 are placed side by side and ready to be spliced, the construction workers can pass the fixing bolt 63 through the threaded hole 62 on one third U-shaped steel 6 and screw it into the corresponding threaded hole 62 on the other third U-shaped steel 6, thus realizing the tight connection of the two U-shaped steels. This connection method is not only simple and fast, but also has high connection strength and stability. The fixing bolt 63 is a fastener for connecting two third U-shaped steels 6. The material, diameter, length and strength grade of the fixing bolt 63 need to be determined according to the specific engineering requirements and the specifications of the third U-shaped steel 6. During the installation process, the construction workers need to ensure that the head and threaded part of the fixing bolt 63 are intact, and need to tighten it according to the specified torque to ensure the reliability and tightness of the connection. Through the mutual cooperation of the fixed block 61, the threaded hole 62 and the fixing bolt 63, two or more third U-shaped steels 6 can be easily spliced into an integral structure. This integral structure not only retains the excellent mechanical properties of a single U-shaped steel, but also enhances the overall strength and stiffness through splicing. At the same time, the modular design makes this splicing method have high flexibility and adjustability, and can be combined in different lengths and widths according to actual needs to adapt to various complex engineering scenarios.

[0033] Combined with Figure 2 、 Figure 3 and Figure 5As shown, two parallel and spaced fixed columns 4 are provided in the front U-shaped grooves of the first U-shaped steel 1 and the second U-shaped steel 2, and a fixed handle 5 is rotatably connected to the fixed columns 4. Specifically, the fixed columns 4 are arranged on both sides inside the front U-shaped grooves of the first U-shaped steel 1 and the second U-shaped steel 2 and are kept parallel and spaced to ensure the stability and balance of the structure. These fixed columns 4 are usually made of high-strength materials such as high-quality steel or alloy materials to withstand the rotational force from the fixed handle 5 and possible other external forces. The fixed handle 5 is connected to the fixed columns 4 through a rotational connection. The main function of the fixed handle 5 is to provide a convenient operation interface, allowing construction workers to adjust or lock certain components of the steel formwork for the distribution network pole foundation by rotating the handle.

[0034] Combined with Figure 2 , Figure 3 and Figure 4 As shown, the fixed handle 5 is of a triangular structure, and cylindrical rings 51 are welded to all three corners of the fixed handle 5. The cylindrical rings 51 at the bottom two corners of the fixed handle 5 are sleeved on the fixed columns 4. Specifically, the fixed handle 5 is designed as a triangular structure. This shape selection is not accidental but is based on various considerations. Firstly, the triangle is one of the most stable shapes in structural mechanics. It can effectively disperse forces when subjected to external forces, reduce stress concentration, and thus enhance the load-bearing capacity and durability of the fixed handle 5. Secondly, the triangular structure provides a better gripping feeling for the operator. Compared with traditional linear or arc-shaped handles, the triangular handle can better fit the shape of the palm when being gripped, reduce hand fatigue, and increase the stability and accuracy of the operation. In addition, the fixed handle 5 with a triangular structure also has a certain visual identification function. In a complex construction environment, this unique shape can quickly attract the attention of operators and help them quickly locate and operate the fixed handle 5. Cylindrical rings 51 are welded to all three corners of the fixed handle 5, realizing the rotational connection between the fixed handle 5 and the fixed columns 4. The inner diameter of the cylindrical ring 51 matches the outer diameter of the fixed column 4, enabling the cylindrical ring 51 to be tightly sleeved on the fixed column 4.
