[0044] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0045] A fan foundation prefabricated part mold 100 according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in Figures 1 to 7 the fan foundation prefabricated part mold 100 according to an embodiment of the present application includes a main mold body 1 and a guide mold 2.

[0046] The main mold body 1 has a main mold cavity 15 extending in a first direction, and a thickness direction of the main mold cavity 15 is a second direction, the first direction being perpendicular to the second direction. The guide mold 2 has a guide cavity 21 extending in the first direction, and the guide mold 2 is connected to the main mold body 1 in the second direction, and the guide cavity 21 is communicated with the main mold cavity 15.

[0047] The fan foundation prefabricated part mold 100 according to the embodiment of the present application is provided with the guide mold 2 on the main mold body 1, and the guide cavity 21 is communicated with the main mold cavity 15, so that when the fluid material (concrete) is injected into the main mold cavity 15, the fluid material can enter the guide cavity 21 through the main mold cavity 15, so that the prefabricated part body in the main mold cavity and the guide column in the guide cavity 21 can be integrally formed after the fluid material is solidified and formed. That is, the prefabricated part produced by the fan foundation prefabricated part mold 100 has a guide column, and the prefabricated part can be a ring-shaped fan foundation 200; or the prefabricated part can be a sheet shape, and a plurality of sheet-shaped prefabricated parts can be connected in the circumferential direction to form a ring-shaped fan foundation 200. The fan foundation 200 is prefabricated by the fan foundation prefabricated part mold 100, so as to reduce the production cost and improve the production efficiency. The inner and outer circumferential profiles of the ring-shaped fan foundation 200 are regular polygons or circles, and the axial direction of the ring-shaped fan foundation 200 is the up-down direction.

[0048] The length directions of the main mold cavity 12 and the guide cavity 21 are both the first direction. Specifically, the length direction of the main mold cavity 12 is the first direction, so that the length of the body prefabricated by the main mold cavity 12 is the first direction, that is, the length direction of the fan foundation 200 is the first direction. The length of the length direction of the guide cavity 21 is the first direction, so that the length of the guide column prefabricated by the guide cavity 21 is consistent with the length of the fan foundation 200. The first direction can be the up-down direction, as shown by the arrow in the figure. For example, the ring-shaped fan foundation 200 is in the up-down direction, so as to facilitate the support of the tower of the fan.

[0049] The guide mold 2 is connected with the main mold body 1 in the second direction, and the guide cavity 2 is communicated with one side of the thickness direction of the main mold cavity 15. Specifically, the guide column prefabricated by the guide cavity 21 is located on the outer surface of the body prefabricated by the main mold cavity 12 in the thickness direction of the fan foundation 200. That is, the ring-shaped fan foundation 200 prefabricated by the fan foundation prefabricated part mold 100 is provided with a plurality of guide columns extending in the up-down direction on the outer circumferential side, and the plurality of guide columns extending in the up-down direction can guide the ring-shaped fan foundation 200, so that the ring-shaped fan foundation 200 is not easy to deviate during sinking, thereby facilitating the installation and construction of the ring-shaped fan foundation 200.

[0050] Therefore, the fan foundation prefabricated part mold 100 according to the embodiment of the present application can produce prefabricated parts with guide columns, thereby reducing the production and installation cost of the fan foundation 200.

[0051] As Figures 1 to 7As shown, the fan foundation prefabricated part mold 100 according to the embodiment of the application comprises a main mold body 1, a guide mold 2 and a reinforcing mold. Specifically, the outer wall surface of the main mold body 1, the guide mold 2 and the reinforcing mold is provided with a reinforcing rib plate 5. The reinforcing rib plate 5 comprises a first rib plate 51 and a second rib plate 52, and the first rib plate 51 and the second rib plate 52 are at an angle. In this way, the structural strength of the main mold body 1, the guide mold 2 and the reinforcing mold can be improved.

[0052] As shown in the drawings, Figures 1 to 3 The main mold body 1 has a main mold cavity 15, the main mold cavity 15 extends along a first direction, and the thickness direction of the main mold cavity 15 is a second direction, and the first direction is perpendicular to the second direction. The second direction can be the front-back direction, as shown by the arrow in the figure. For example, the thickness direction of the main mold cavity 15 is the front-back direction.

[0053] In some embodiments, the main mold cavity 15 is in the shape of a sheet, and the main mold cavity 15 can form a sheet-shaped prefabricated part body, and a plurality of sheet-shaped prefabricated part bodies are connected in a circumferential direction to form a ring-shaped main body of the fan foundation 200. For example, the main mold cavity 15 is a cavity in the shape of a flat plate perpendicular to the second direction. Alternatively, the main mold cavity 15 is a cavity with a curved surface extending along the first direction.

[0054] As shown in the drawings, Figures 1 to 5 In some embodiments, the main mold cavity 15 is a cavity in the shape of a flat plate perpendicular to the second direction. The main mold cavity 15 comprises a first wall surface 111, a second wall surface 121, a third wall surface 131 and a fourth wall surface 141.

[0055] The first wall surface 111 and the second wall surface 121 are oppositely arranged in the second direction, and the first wall surface 111 and the second wall surface 121 are both perpendicular to the second direction. The third wall surface 131 and the fourth wall surface 141 are oppositely arranged in the third direction, and the first wall surface 111, the third wall surface 131, the second wall surface 121 and the fourth wall surface 141 are sequentially connected, and any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0056] Specifically, the first wall surface 111, the second wall surface 121, the third wall surface 131 and the fourth wall surface 141 are all flat surfaces, and the size of the first wall surface 111 in the third direction is greater than the size of the second wall surface 121 in the third direction. The third wall surface 131 and the fourth wall surface 141 are both connected to the edges of the first wall surface 111 and the second wall surface 121, i.e. the third wall surface 131 and the fourth wall surface 141 are both inclined surfaces. Thus, the first wall surface 111 of the prefabricated part body formed by the main mold cavity 15 defines the outer surface of the prefabricated part body, the second wall surface 121 defines the inner surface of the prefabricated part body, and the third wall surface 131 and the fourth wall surface 141 define the inclined side surfaces of the prefabricated part body, so that the abutment and connection of two prefabricated part bodies are achieved through the side surfaces.

[0057] The third direction can be the left and right direction, as shown by the arrows in the figure. For example, the third wall 131 and the fourth wall 141 are arranged opposite each other in the left and right direction. The size of the first wall 111 in the left and right direction is larger than that of the second wall 121 in the left and right direction. The first wall 111 is located in front of the second wall 121, and the third wall 131 is located to the left of the fourth wall 141.

[0058] like Figures 1 to 5 As shown, in some embodiments, the main mold body 1 includes a first template 11, a second template 12, a third template 13, and a fourth template 14. The first template 11 and the second template 12 are arranged opposite each other in a second direction, and the third template 13 and the fourth template 14 are arranged opposite each other in a third direction. Each of the first template 11, the second template 12, the third template 13, and the fourth template 14 has a reinforcing rib 5 on its exposed outer surface. The main mold body 1 has sealing plates on both sides in the first direction to cover the main mold cavity 15.

[0059] like Figures 1 to 5 As shown, the thickness direction of the first template 11 and the thickness direction of the second template 12 are both the second direction. The inner wall surface of the first template 11 forms the first wall surface 111, and the inner wall surface of the second template 12 forms the second wall surface 121. For example, the thickness direction of the first template 11 and the thickness direction of the second template 12 are both the front-rear direction, and the first template 11 is located on the front side of the second template 12.

[0060] The first portion of the inner wall of the third template 13 constitutes the third wall 131, and the second portion of the wall of the fourth template 143 constitutes the fourth wall 141. The first template 11, the third template 13, the second template 12, and the fourth template 14 are connected sequentially. The thickness directions of both the third template 13 and the fourth template 14 form an angle with the third direction. That is, the third template 13 and the fourth template 14 are plates inclined to the third direction. For example, the front portion of the inner wall of the third template 13 constitutes the third wall 131, and the front portion of the wall of the fourth template 14 constitutes the fourth wall 141.

[0061] like Figure 5As shown, in some embodiments, the main mold cavity 15 further comprises a heel surface 112, which is a bevel. The heel surface 112 is connected to the first wall surface 111 at one end in the first direction and faces the second wall surface 121 in the second direction. The distance between the heel surface 112 and the second wall surface 121 in the second direction decreases in a direction away from the first wall surface 111 in the first direction. Thus, the end of the main mold cavity 15 in the first direction can be reduced in size in a direction adjacent to the end surface, so that the outer surface of the main body of the prefabricated part formed by the main mold cavity 15 is a beveled heel surface. Specifically, the main mold body 1 further comprises a heel plate connected to the first mold plate 11 at one end in the first direction, and the inner wall surface of the heel plate forms the heel surface 112. For example, the first mold plate 11 and the heel plate are integrally formed, the heel surface 112 is located below the first wall surface 121, and the distance between the heel surface 112 and the second wall surface 121 in the front-back direction decreases downward, so that the outer surface of the bottom of the fan foundation 200 is inwardly tapered downward, facilitating the sinking of the fan foundation 200. For example, the heel 3 is a regular octagonal ring.

[0062] As shown, Figures 1 to 5 The guide mold 2 has a guide cavity 21 extending in the first direction, and the guide mold 2 is connected to the main mold body 1 in the second direction, and the guide cavity 21 communicates with the main mold cavity 15. Specifically, the first mold plate 11 is provided with a first through hole penetrating through it in the second direction, the size of the first through hole in the first direction is equal to that of the guide cavity 21, and the guide mold 2 is arranged on the outer wall surface of the first mold plate 11 and covers the first through hole, so that the guide cavity 21 communicates with the main mold cavity 15 through the first through hole. Thus, the concrete can enter the guide cavity 21 through the main mold cavity 15, so that the guide cavity 21 forms a guide column connected to the main body of the prefabricated part. For example, the guide mold 2 is arranged on the front side of the first mold plate 11.

[0063] As shown, Figure 5 In some embodiments, the guide mold 2 is a plurality of guide molds 2 arranged in the first direction, and the plurality of guide molds 2 define a plurality of guide cavities 21 arranged in the first direction, and the size of the guide cavity 21 in the first direction is less than or equal to that of the main mold cavity 15 (the first wall surface 111). Thus, the prefabricated part formed has a plurality of guide columns arranged in the first direction on the main body. For example, the plurality of guide molds 2 are arranged in the up-down direction, and the distance between two adjacent guide cavities 2 in the up-down direction is greater than or equal to 2 meters.

[0064] In some embodiments, the cross section of the guide cavity 21 is triangular, and the size of the guide cavity 21 in the third direction decreases in a direction away from the main mold cavity 15. Thus, the guide column formed by the guide cavity 21 facilitates the guidance of the end away from the main body of the prefabricated part. For example, the cross section of the guide cavity 21 is isosceles triangular.

[0065] Specifically, the guide die 2 comprises a first guide plate 22, a second guide plate 23 and two guide side plates 24, and the outer surfaces of the first guide plate 22, the second guide plate 23 and the two guide side plates 24 are provided with reinforcing ribs 5.

[0066] The first guide plate 22 and the second guide plate 23 extend along a first direction, and the thickness direction of the guide side plate 24 is the first direction. The first guide plate 22 is connected to the second guide plate 23 at an angle, and the two guide side plates 24 are located on both sides of the first guide plate 22 and the second guide plate 23 in the first direction. The two guide side plates 24 are connected to the first guide plate 22 and the second guide plate 23, and the first guide plate 22, the second guide plate 23 and the two guide side plates 24 are connected to the outer wall surface of the first die plate 11 and define a guide cavity 21. For example, the size of the guide cavity 21 in the left-right direction decreases forward. The length direction of the first guide plate 22 and the second guide plate 23 is the up-down direction, and the thickness direction of the guide side plate 24 is the up-down direction. The guide side plate 24 is a triangular plate body, and the two guide side plates 24 are located on both sides of the first guide plate 22 and the second guide plate 23 in the up-down direction. The rear side of the first guide plate 22, the second guide plate 23 and the two guide side plates 24 is connected to the front wall surface of the first die plate 11 and defines the guide cavity 21.

[0067] As shown in Figures 1 to 5 The reinforcing die has a reinforcing cavity, the reinforcing cavity is in communication with the main die cavity 15, the reinforcing die is connected to the main die body 1, the guide die 2 is located on both sides of the main die body 1 in the second direction, and the reinforcing cavity has a preset size in at least one of the third direction and the first direction. Specifically, the second die plate 12 is provided with a second through hole penetrating therethrough, and the reinforcing die is arranged on the outer wall surface of the second die plate 12 and covers the second through hole, and the reinforcing cavity is in communication with the main die cavity 15 through the first through hole. In this way, the concrete in the main die cavity 15 can enter the reinforcing cavity, so that the reinforcing beam located inside the main body of the prefabricated part is formed in the reinforcing cavity, thereby improving the structural strength of the prefabricated part. For example, the reinforcing die is located on the rear side of the main die body 1. For example, the guide cavity can be one of a cylindrical cavity, a semicircular cylindrical cavity and a polygonal cylindrical cavity.

[0068] As shown in Figures 1 to 5As shown, in some embodiments, the reinforcing mold includes a plurality of first reinforcing molds 3 and a plurality of second reinforcing molds 4. The plurality of first reinforcing molds 3 are spaced apart along a first direction, and each first reinforcing mold 3 has a first reinforcing cavity 31 extending along a third direction. Each second reinforcing mold 4 has a second reinforcing cavity 41 extending along the first direction. Any two of the first reinforcing cavities 31, the second reinforcing cavities 41, and the main mold cavity 15 are interconnected. Each first reinforcing mold 3 has a second reinforcing mold 4 at both ends in the first direction. Thus, the first reinforcing beam formed in the first reinforcing cavity 31 and the second reinforcing beam formed in the second reinforcing cavity 32 can be perpendicular to each other and connected, so that the first and second reinforcing beams cooperate with each other and improve the structural strength of the precast component.

[0069] like Figures 1 to 5 As shown, each first reinforcing mold 3 includes a first reinforcing plate 32, a second reinforcing plate 33, and a third reinforcing plate 34. The thickness directions of the first reinforcing plate 32 and the second reinforcing plate 33 are both in a first direction, and the thickness direction of the third reinforcing plate 34 is in a second direction. The first reinforcing plate 32 and the second reinforcing plate 33 are arranged opposite to each other in the first direction, and the two ends of the third reinforcing plate 34 are connected to the first reinforcing plate 32 and the second reinforcing plate 33 respectively in the first direction. After multiple prefabricated parts are connected, the multiple first reinforcing beams formed by the multiple first reinforcing molds 3 can be connected circumferentially to form a ring-shaped reinforcing beam.

[0070] Each of the first reinforcing plate 32, the second reinforcing plate 33, and the third reinforcing plate 34 is connected to the third template 13 and the third template 13 at both ends in the third direction. The first reinforcing plate 32, the second reinforcing plate 33, the third reinforcing plate 34, the third template 13, and the third template 13 define the first reinforcing cavity 31. That is, the first reinforcing plate 32, the second reinforcing plate 33, and the third reinforcing plate 34, together with the third wall surface 131 of the third template 13 and the fourth wall surface 141 of the fourth template 14 of the main mold body 1, define the first reinforcing cavity 31. The first reinforcing cavity 31 can be formed into a first reinforcing beam extending in the third direction.

[0071] For example, the thickness directions of the first reinforcing plate 32 and the second reinforcing plate 33 are both vertical, while the thickness direction of the third reinforcing plate 34 is horizontal. The length directions of the first reinforcing plate 32, the second reinforcing plate 33, and the third reinforcing plate 34 are all horizontal. The two ends of the third reinforcing plate 34 in the vertical direction are connected to the rear ends of the first reinforcing plate 32 and the second reinforcing plate 33, respectively. The front ends of the first reinforcing plate 32 and the second reinforcing plate 33 are both connected to the second template 12. The left and right ends of the first reinforcing plate 32, the second reinforcing plate 33, and the third reinforcing plate 34 are connected to the third wall surface 131 of the third template 13 and the fourth wall surface 141 of the fourth template 14 of the main mold body 1, respectively. The first reinforcing cavity 31 can form a first reinforcing beam extending in the horizontal direction.

[0072] As shown in Figures 1 to 5 Each second reinforcing die 4 includes a fourth reinforcing plate 42, a fifth reinforcing plate 43 and a sixth reinforcing plate 44. The thickness direction of the fourth reinforcing plate 42 and the thickness direction of the fifth reinforcing plate 43 are both the third direction, and the thickness direction of the sixth reinforcing plate 44 is the second direction. The fourth reinforcing plate 42 and the fifth reinforcing plate 43 are oppositely arranged in the third direction, and the two ends of the sixth reinforcing plate 44 in the third direction are connected with the fourth reinforcing plate 42 and the fifth reinforcing plate 43 respectively. The fourth reinforcing plate 42, the fifth reinforcing plate 43 and the sixth reinforcing plate 44 define at least part of the second reinforcing cavity 41.

[0073] Specifically, at least one end of the fourth reinforcing plate 42, the fifth reinforcing plate 43 and the sixth reinforcing plate 44 in the first direction is connected with the first reinforcing die 3 (the first reinforcing plate 32 and the second reinforcing plate 33), and the fourth reinforcing plate 42, the fifth reinforcing plate 43 and the sixth reinforcing plate 44 are all connected with the second mold plate 12. The second reinforcing die 4 at the end in the first direction further includes a reinforcing side plate 45 covering the second reinforcing cavity. The second reinforcing cavity 41 can be shaped into a second reinforcing beam extending in the first direction.

[0074] For example, the thickness direction of the fourth reinforcing plate 42 and the thickness direction of the fifth reinforcing plate 43 are both the left-right direction, the thickness direction of the sixth reinforcing plate 44 is the front-back direction, and the length direction of the fourth reinforcing plate 42, the fifth reinforcing plate 43 and the sixth reinforcing plate 44 is the up-down direction. The fourth reinforcing plate 42 and the fifth reinforcing plate 43 are oppositely arranged in the left-right direction, and the two ends of the sixth reinforcing plate 44 in the left-right direction are connected with the rear end of the fourth reinforcing plate 42 and the rear end of the fifth reinforcing plate 43 respectively. The front end of the fourth reinforcing plate 42 and the front end of the fifth reinforcing plate 43 are connected with the first mold plate 12, and the second reinforcing cavity 41 can be shaped into a second reinforcing beam extending in the up-down direction.

[0075] In some embodiments, the guide mold 2 is fixed on the first mold plate 11, the reinforcing mold is fixed on the second mold plate 12, and each of the reinforcing mold, the first mold plate 11 and the second mold plate 12 is detachably connected with the third mold plate 13 and the fourth mold plate 14. Specifically, when the concrete is poured into the wind turbine foundation prefabricated part mold 100, the wind turbine foundation prefabricated part mold 100 is laid flat so that the thickness direction of the prefabricated part is consistent with the up-down direction, thereby facilitating the transportation of the prefabricated part, and when the prefabricated part is installed, the prefabricated part can be placed vertically so that the length direction of the prefabricated part is consistent with the up-down direction. That is, when the concrete is poured, the first wall surface 111 faces the lower side, and the second wall surface 121 faces the upper side. In this way, the reinforcing mold is fixed on the second mold plate 12, which can facilitate the support of the second mold plate 12 by the reinforcing mold. The guide mold 2 is fixed on the first mold plate 11, which can facilitate the support of the guide mold 2 by the first mold plate 12. The third mold plate 13 and the fourth mold plate 14 are located on both sides of the first mold plate 11 and the second mold plate 12 in the horizontal direction, which can facilitate the disassembly of the mold. For example, the first guide plate 22 and the second guide plate 23 are fixed on the first mold plate 11, and the first reinforcing mold 3 and the second reinforcing mold 4 are fixed on the second mold plate 4. Each of the first reinforcing mold 3, the first mold plate 11 and the second mold plate 12 is detachably connected with the third mold plate 13 and the fourth mold plate 14 at both ends in the third direction through bolts.

[0076] In some embodiments, the first pipe body and the second pipe body are arranged in the main mold cavity 15, the first pipe body abuts against the first wall surface 111 and the third wall surface 131, and the second pipe body abuts against the fourth wall surface 141. In this way, the first pipe body in the prefabricated part body after molding can define a first connecting hole, the second pipe body in the prefabricated part body can define a second connecting hole, and the connecting piece (bolt) passing through the first connecting hole of one of the two adjacent prefabricated part bodies and the second connecting hole of the other can connect the two adjacent prefabricated part bodies.

The wind turbine foundation manufacturing method according to the embodiments of the application comprises the following steps:

[0078] The reinforcing member is placed in the main mold cavity 15 of the wind turbine foundation prefabricated part mold 100. Specifically, the reinforcing member connected with the reinforcing member in the main mold cavity 15 can also be placed in the guide cavity and the reinforcing cavity, so as to improve the structural strength of the prefabricated part.

[0079] The concrete is poured into the main mold cavity 15 and the guide cavity 21 of the wind turbine foundation prefabricated part mold 100. Specifically, when the reinforcing cavity is provided, the concrete can also enter the reinforcing cavity, and the pouring of the concrete is completed and the molding is waited.

[0080] After the concrete in the fan foundation precast mold 100 is formed into a precast, the fan foundation precast mold 100 is removed. Thus, the desired precast is obtained, and the outer surface of the precast is formed with a guide column.

[0081] The plurality of precasts are connected in sequence in the circumferential direction to form a ring-shaped fan foundation 200. For example, in a cross section perpendicular to the up-down direction, eight precasts are connected in sequence in the circumferential direction so that the inner and outer circumferential profiles of the fan foundation 200 are regular octagons.
