Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power equipment construction, in particular to a prefabricated foundation base for electric poles specially used in coastal tidal flat areas. Background Art
[0002] Usually when arranging electric poles, it is only necessary to use a cement-cast base or bury the electric poles directly underground to ensure the stability of the electric poles after installation. However, this situation only applies to situations where the soil properties are stable and the soil is strong enough. For coastal tidal flats, since the soil is relatively soft, the stability of electric poles is insufficient if they are installed only by burying electric poles or prefabricated cement bases. Moreover, the soil properties in coastal tidal flats are not stable enough and are easily affected by the infiltration of various components in seawater, which makes the electric poles easily corroded by alkaline after installation. Therefore, alkali resistance and corrosion resistance should also be considered when installing electric poles. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a prefabricated foundation base for electric poles specially used in coastal tidal flat areas in view of the above-mentioned technical deficiencies. The prefabricated foundation base can improve the stability of electric poles installed in soft soil, has strong alkali resistance and corrosion resistance, and ensures the service life.
[0004] The technical solution adopted by the utility model is: to provide a prefabricated basic base of a power pole specially used in coastal tidal flat areas, comprising a cylindrical support base arranged in a vertical direction; a bracket for connecting a power pole body is coaxially fixed on the upper end of the support base; the lower end of the power pole body is correspondingly inserted in the bracket; a support flange is sleeved and fixed on the lower part of the power pole body; the support flange and the bracket are connected by a plurality of locking bolts; a through hole is opened in the middle of the lower end of the bracket; an expansion mechanism is arranged inside the support base;
[0005] The expansion mechanism includes an axle seat fixed in the middle of the lower end of the support base; a gear control shaft is coaxially arranged inside the support base; the lower end of the gear control shaft is correspondingly plugged into the axle seat and rotates with the axle seat; a limiting block is coaxially fixed to the upper end of the gear control shaft; the limiting block passes through the through hole correspondingly and rotates with the through hole; a limiting groove is opened in the middle of the upper end of the limiting block; a plurality of supporting slide rails are fixed from top to bottom inside the support base; the supporting slide rails are arranged in the horizontal direction; the upper and lower adjacent supporting slide rails are staggered with each other in the horizontal direction; the two ends of the supporting slide rails are respectively connected to the outer wall of the support base through the through-opening; an expansion rack is slidably connected inside the support slide rail; the expansion rack is meshed with the gear control shaft; the expansion rack corresponds to the through-opening; the surfaces of the support base, the bracket and the expansion rack are all coated with a polyurethane coating.
[0006] To further optimize the technical solution, a prefabricated foundation base for electric poles specially used in coastal tidal flat areas has a plurality of ground nails fixed to the lower end of the support base.
[0007] To further optimize the technical solution, a prefabricated foundation base for electric poles specially used in coastal tidal flat areas has a limiting envelope slidingly sleeved on the outside of the supporting base.
[0008] To further optimize the technical solution, an expansion plate is fixedly sleeved on the outside of a bracket of a prefabricated foundation base of a utility pole specially used in coastal tidal flat areas.
[0009] The beneficial effects of the utility model are:
[0010] 1. The support base can be buried in the soil. By rotating the gear control shaft, the expansion rack can slide along the support rail, so that the expansion rack can extend from the through-hole and insert into the soil, thereby expanding the support range of the support base and utilizing the blocking effect of the soil on the expansion rack to improve the firmness of the support base in the soil.
[0011] The upper and lower adjacent support rails are staggered in the horizontal direction, so that multiple expansion racks can be inserted into the soil from multiple directions, further improving the support range of the support base while distributing the expansion racks in various directions in the soil, which is beneficial to sharing the stress to various parts of the soil, thereby reducing the local stress in various parts of the soil, effectively improving the stability of the soil, and making the installation of the pole more secure.
[0012] 2. The lower end of the gear control shaft is plugged into the shaft seat and rotates with the shaft seat. A limiting block is coaxially fixed to the upper end of the gear control shaft. The limiting block passes through the through hole and rotates with the through hole. After the expansion rack is inserted into the soil, the gear control shaft can be easily removed and reused to reduce costs.
[0013] 3. The surfaces of the support base, bracket and expansion rack are all coated with polyurethane coating. The polyurethane coating has strong stability, alkali resistance and corrosion resistance, which can ensure the service life of this prefabricated foundation base in coastal tidal flat areas.

DETAILED DESCRIPTION
[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] like Figure 1 , Figure 3 As shown, a prefabricated foundation base for electric poles specially used in coastal tidal flat areas comprises a cylindrical support base 1 arranged in the vertical direction; a bracket 2 for connecting an electric pole body 16 is coaxially fixed to the upper end of the support base 1; the lower end of the electric pole body 16 is correspondingly inserted into the bracket 2; a support flange 3 is sleeved and fixed to the lower part of the electric pole body 16; the support flange 3 and the bracket 2 are connected by a plurality of locking bolts 4; a through hole 5 is opened in the middle of the lower end of the bracket 2; an expansion mechanism is arranged inside the support base 1;
[0022] like Figure 2-4 As shown, the expansion mechanism includes an axle seat 6 fixed at the middle part of the lower end of the support base 1; a gear control shaft 7 is coaxially arranged inside the support base 1; the lower end of the gear control shaft 7 is correspondingly plugged into the axle seat 6 and rotates with the axle seat 6; a limiting block 8 is coaxially fixed to the upper end of the gear control shaft 7; the limiting block 8 passes through the through hole 5 and rotates with the through hole 5; a limiting groove 9 is opened in the middle part of the upper end of the limiting block 8; a plurality of support slide rails 10 are fixed from top to bottom inside the support base 1; the support slide rails 10 are arranged in the horizontal direction; the upper and lower adjacent support slide rails 10 are staggered with each other in the horizontal direction; the two ends of the support slide rails 10 are respectively connected to the outer wall of the support base 1 through the through-hole 11; an expansion rack 12 is slidably connected inside the support slide rail 10; the expansion rack 12 is meshed and connected with the gear control shaft 7; the expansion rack 12 corresponds to the through-hole 11; the surfaces of the support base 1, the bracket 2 and the expansion rack 12 are all coated with a polyurethane coating.
[0023] First, bury the support base 1 in the soil, and then rotate the gear control shaft 7 to drive the meshed expansion rack 12 to slide along the support slide rail 10, so that the expansion rack 12 is respectively inserted into various positions of the soil outside the support base 1. When rotating the gear control shaft 7, a wrench can be used to plug into the limiting groove 9 on the limiting block 8, and the gear control shaft 7 can be driven by rotating the wrench.
[0024] By inserting the expansion rack 12 into the soil outside the support base 1 from various directions, on the one hand, the expansion rack 12 is blocked by the soil to increase the stability of the support base 1 and expand the support range. On the other hand, the expansion rack 12 is distributed in various directions in the soil, which is conducive to sharing the stress to various parts of the soil, thereby reducing the local stress in various parts of the soil, effectively improving the stability of the soil, and making it difficult for the pole body 16 to loosen even the relatively soft soil when it is subjected to external force. The above method makes it more stable when the support base 1 is arranged in the soft soil of the coastal tidal flat area.
[0025] After the support base 1 is buried in the soil, the gear control shaft 7 is pulled out from above the bracket 2 for reuse, and then concrete is poured into the support base 1 using the through hole 5. The solidification of the concrete increases the weight of the support base 1 on the one hand, so that the center of gravity is stable when supporting the pole body 16. On the other hand, the solidification of the concrete fixes the expansion rack 12 and the support base 1, ensuring the firmness of the expansion rack 12 inserted into the soil.
[0026] After the support base 1 is buried, the pole body 16 is inserted into the bracket 2, and then the pole body 16 and the bracket 2 are connected by locking bolts 4 to achieve the layout of the pole body 16.
[0027] It should be noted that the support base 1 is made of a material of concrete mixed with steel bars to ensure that it has sufficient supporting strength and service life.
[0028] The surfaces of the support base 1, the bracket 2 and the expansion rack 12 are all coated with a polyurethane coating, which has strong stability, alkali resistance and corrosion resistance, and can ensure the service life of the prefabricated foundation base in coastal tidal flat areas.
[0029] like Figure 5 As shown, a plurality of ground-inserting nails 13 are fixed at the lower end of the support base 1. The ground-inserting nails 13 are inserted into the soil to achieve initial positioning of the support base 1, which is beneficial to prevent the support base 1 from moving when the gear control shaft 7 is rotated.
[0030] like Figure 5 As shown, the support base 1 is slidably sleeved with a limiting sleeve 14 on the outside. The limiting sleeve 14 can prevent the expansion rack 12 from passing through the through-hole 11 in advance during the transportation or transfer of the support base 1, thereby ensuring reliability, and the limiting sleeve 14 can be removed before the support base 1 is placed in the preset soil position.
[0031] like Figure 5 As shown, an expansion plate 15 is sleeved and fixed on the outside of the bracket 2. The expansion plate 15 can be buried in the soil, further increasing the supporting area between the soil and improving the anti-toppling performance of the electric pole body 16.
