[0002] A fan is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. The civil construction of a fan is a series of construction work such as foundation pit excavation, casting and tower erection before the installation of the fan. After the excavation of the foundation pit is completed, the inside of the foundation pit needs to be supported to prevent the internal walls of the foundation pit from being subjected to external stress and thus collapse. The foundation pit support frame currently used for the civil construction of the fan is basically assembled through chain plates, and it is necessary to manually splice and assemble the wooden boards piece by piece to support the inside of the foundation pit. However, after the foundation pit is dug, due to the natural influence of the groundwater system or rainy weather, the foundation pit is prone to water seepage on the foundation pit wall, causing water to accumulate in the foundation pit, which slows down the installation of the support frame and takes a long time. In addition, under the influence of accumulated water, the soil blocks on the foundation pit wall are easy to fall off, resulting in the need for multiple cleaning in the foundation pit. In view of this, we propose a new type of foundation pit support frame for civil construction of fans. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] To solve the problem of water accumulation in the foundation pit, please refer to Figure 1-Figure 5The present embodiment provides a wind turbine civil construction pit support frame, including a base 1, and pins 2 are provided on the base 1 and the support frame 34. The pins 2 are passed through the base 1 and the support frame 34 and nailed to the ground of the base to increase its stability. A guard frame assembly 3 is provided on the base 1, and the base 1 is used to carry the guard frame assembly 3. The guard frame assembly 3 includes a protective shell 31, and the protective shell 31 is used to protect its internal structure and provide a storage space for the chain plate 331. The protective shell 31 is provided with a winding assembly 32 and a symmetrically arranged unwinding assembly 33 for supporting the inner wall of the foundation pit. The unwinding assembly 33 includes a chain plate 331 fixedly connected to a rotating rod 321, and the chain plate 331 is used to support the foundation pit wall. The other end of the chain plate 331 is provided with a detachably connected support rod 332, and the chain plate 331 and the support rod 332 can be connected by bolts, which is convenient for disassembly and installation. The support rod 332 is used to support and connect the chain plate 331. A water outlet pipe 45 is provided in the support rod 332, and a plurality of cone soil nails 5 are fixedly connected to one end of the support rod 332. The cone soil nails 5 are sharp at the front end and wide at the rear end. The cone soil nails 5 are used to penetrate into the foundation pit wall, increase the fit of the chain plate 331 to the foundation pit wall, and improve the support effect. The winding assembly 32 is used to collect the unwinding assembly 33. A support frame 34 is provided below the unwinding assembly 33. The support frame 34 is used to carry the unwinding assembly 33 and the drainage assembly 4. The support frame 34 is provided with a drainage assembly 4 for draining water in the foundation pit. The drainage assembly 4 includes a water retaining frame 44 provided between the base 1 and the support frame 34. The water retaining frame 44 is used to block the water sliding down from the foundation pit wall so that it will not flow further into the foundation pit. The water retaining frame 44 is provided with a protrusion, and the base 1 and the support frame 34 are provided with grooves adapted to the protrusion, so that the water retaining frame 44 can be quickly installed and disassembled between the base 1 and the support frame 34. A water storage tank 441 is provided in the water retaining frame 44. The water storage tank 441 is used to collect water, so that the water pump 41 can pump water out of the foundation pit. The support frame 34 is connected to the water pump 41, and the water pump 41 serves as a power source for pumping water. A water suction pipe 42 is connected to one end of the water pump 41, and the water suction pipe 42 is used to absorb water in the water storage tank 441. The other end of the water pump 41 is fixedly connected to a water outlet pipe 45. When the foundation pit wall seeps water, since the foundation pit is dug downward, a height difference with the original ground is generated, and there is an underground water system underground, which makes it easy for water to accumulate in the foundation pit. After the foundation pit is dug, the chain plate 331 is pulled out of the protective shell 31, and the chain plate 331 is fixed and attached to the foundation pit wall for support under the action of the support frame 34, the support rod 332 and the cone soil nail 5. When water seeps from the foundation pit wall, the water will flow to the bottom of the foundation pit. At this time, the water will be blocked by the water retaining frame 44, and the water will be collected by the water storage tank 441. The water pump 41 will be turned on to allow the water to flow through the suction pipe 42 and the water will be discharged into the foundation pit through the outlet pipe 45 through the operation of the water pump 41, thereby preventing water from accumulating in the foundation pit and improving the progress of installing the support frame for the foundation pit.

[0034] Considering that the outlet pipe 45 is too long to be stored, and too short to discharge water into the foundation pit, refer to Figure 1-Figure 5Therefore, a connector 46 is provided at the end of the water outlet pipe 45, and water pipes of different lengths can be connected to the water outlet pipe 45 through the connector 46, so that the water in the foundation pit can be discharged from the foundation pit through the water outlet pipe 45 and can be easily stored.

[0035] Considering that the chain plate 331 needs to be retracted after the foundation pit construction is completed, refer to Figure 1-Figure 5 Therefore, the winding assembly 32 includes a rotating rod 321 rotatably connected to the base 1, the rotating rod 321 is used to rotate and collect the chain plate 331, the rotating rod 321 is symmetrically provided with connecting grooves 322, the connecting grooves 322 are used to connect the chain plates 331, and one end of the rotating rod 321 is fixedly connected to a winding wheel 323. The winding wheel 323 is used to provide better force when rotating the rotating rod 321. When collecting the chain plate 331, the rotating rod 321 is rotated to roll the chain plate 331 on the rotating rod 321, so that the chain plate 331 is rolled up in the protective shell 31, reducing the cumbersome operation during manual disassembly, improving work efficiency and facilitating storage.

[0036] Example 2

[0037] Based on Example 1, considering that when the water pump 41 extracts water from the foundation pit, there will be soil blocks and other impurities in the water, refer to Figure 1-Figure 5 Therefore, a filter plate 43 is fixedly connected to one end of the water suction pipe 42, and a plurality of first filter holes 442 are evenly distributed on the surface of the water retaining frame 44. The first filter hole 442 is a circular hole, and the first filter hole 442 is used to preliminarily filter impurities in the water. A filter plate 43 is fixedly connected to one end of the water suction pipe 42, and a plurality of second filter holes 431 are evenly distributed on the surface of the filter plate 43. The second filter holes 431 are used to filter the water in the second step, and the size of the second filter holes 431 is smaller than the first filter holes 442. Before the water pump 41 pumps water, the water is filtered through the first filter holes 442. Under the size of the first filter holes 442, larger particles will not enter the water storage tank 441, and the size of the first filter holes 442 is too small, which will affect the speed of water flowing into the water storage tank 441. The size of the first filter holes 442 will not affect the speed of water flowing into the water storage tank 441, and thus will not affect the speed of the water pump 41 pumping water from the foundation pit. After the water is filtered through the first filter hole 442 , the impurities in the water are further filtered through the second filter hole 431 , so that the water pump 41 will not be damaged by larger impurities when pumping water from the foundation pit, thereby improving work efficiency.

[0038] Considering that people cannot see the foundation pit clearly at night or when the lighting is poor, it is easy for people to fall into the foundation pit. Figure 1-Figure 5Therefore, a warning light 6 is fixedly connected to the top of the support rod 332. When it is night and the lighting is poor, the warning light 6 is automatically turned on to emit a striking light through the automatic control of the chip. The warning light 6 is made of reflective material. When there is weak light, it will produce reflections. Through the action of the warning light 6, people can easily and clearly see the striking light, so that they know that this is a foundation pit, reducing the risk of people falling into the foundation pit.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
