Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power generation engineering, and in particular to a device for preventing water accumulation in pile foundations. Background Art

[0002] In recent years, the scale of new energy installed capacity has grown rapidly. With the increasing number of photovoltaic power stations year by year, the land resources in areas with good construction conditions such as sufficient sunlight and flat terrain are decreasing. The construction of photovoltaic power stations in areas with inferior construction conditions such as agriculture, animal husbandry, lakes, and mountains has become a priority form of photovoltaic power station construction. Among them, mountain photovoltaic power stations with more complex topography are the most prominent. In mountain photovoltaic power stations, due to the rugged terrain and large mountain slopes, the pile foundation location is easily accumulated and eroded by rainwater all year round. The quality of the pile foundation is a key link in the construction quality of new energy photovoltaic projects, and the pile components are the main force-bearing parts in the photovoltaic structure. Therefore, the quality of the pile foundation construction plays a vital role in the overall structural stability and installability of the photovoltaic power station.

[0003] In conventional ground photovoltaic power stations, the terrain is flat and the geological changes are not significant. The annual precipitation forms runoff through surface infiltration, ground vegetation interception and designed drainage ditches. No matter what form the pile foundation exists in, it can ensure that the pile foundation position is not affected by rainfall, and the pile foundation position will not be eroded, rainwater accumulation and other phenomena will not occur, resulting in the pile foundation being exposed and the bearing capacity being reduced. In mountain photovoltaic power stations with complex terrain, due to the complex and changeable terrain, geology, geomorphology and hydrology, the pile foundation is mostly constructed on slopes with slope angles ranging from 20 to 40°. Under a certain scale of rainfall, the newly built mountain photovoltaic power station will have a reduced interception and absorption effect of vegetation on rainwater and loose soil disturbed by construction due to the destruction of the original surface landform by local construction. Although loose soil can easily improve the infiltration capacity of precipitation, when the precipitation exceeds a certain scale and natural runoff is formed on the surface, the pile foundation position is particularly prone to erosion and water accumulation. This causes soil erosion, affects the bearing capacity of the pile foundation and thus affects the structural safety of the power station. Summary of the invention

[0026] In recent years, the scale of new energy installed capacity has grown rapidly. With the increasing number of photovoltaic power stations year by year, the land resources in areas with good construction conditions such as sufficient sunlight and flat terrain are decreasing. The construction of photovoltaic power stations in areas with inferior construction conditions such as agriculture, animal husbandry, lakes, and mountains has become a priority form of photovoltaic power station construction.

Therefore, the quality of the pile foundation construction plays a vital role in the overall structural stability and installability of the photovoltaic power station.

[0027] In conventional ground photovoltaic power stations, the terrain is flat and the geological changes are not significant. The annual precipitation forms runoff through surface infiltration, ground vegetation interception and designed drainage ditches. No matter what form the pile foundation exists in, it can ensure that the pile foundation position is not affected by rainfall, and the pile foundation position will not be eroded, rainwater accumulation and other phenomena will not occur, resulting in the pile foundation being exposed and the bearing capacity being reduced.

Although loose soil can easily improve the infiltration capacity of precipitation, when the precipitation exceeds a certain scale and natural runoff is formed on the surface, the pile foundation position is particularly prone to erosion and water accumulation. This causes soil erosion, affects the bearing capacity of the pile foundation and thus affects the structural safety of the power station.

[0028] Reference Figure 1 , Figure 2 , Figure 3 The present application provides a device for preventing water accumulation in a pile foundation, comprising an angle steel plate 100 , a connecting rod 200 and a clamp 300 .

[0029] The angle steel plate 100 includes two side plates 110 connected at an angle. The angle steel plate 100 is used to be inserted into the foundation of the water-facing side of the pile foundation. The convex surface of the angle steel plate 100 faces the water-facing side. Rotating structures 400 are respectively arranged at both ends of the connecting rod 200. At least one connecting rod 200 is arranged on each of the two side plates 110 of the angle steel plate 100. The connecting rod 200 is connected to the side plate 110 of the angle steel plate 100 through the rotating structure 400. The hoop 300 includes a first hoop 310 and a second hoop 320. The first hoop 310 and the second hoop 320 are used to tightly hoop on the pile foundation. The first hoop 310 and the second hoop 320 are detachably connected. A plurality of connecting seats 311 are arranged on the first hoop 310 or the second hoop 320. The rotating structure 400 at the other end of each connecting rod 200 is detachably connected to each connecting seat 311.

[0030] During the use process, the angle steel plate 100 is inserted into the foundation of the water-facing side of the pile foundation so that the angle steel plate 100 is at a certain distance from the ground. Then, the first hoop 310 and the second hoop 320 of the hoop 300 are tightly hooped on the pile foundation, and the connecting rod 200 on the angle steel plate 100 is connected to the connecting seat 311 on the first hoop 310, so that the connecting rod 200 forms a support for the angle steel plate 100. When there is water flow rushing towards the pile foundation on the slope, the angle steel plate 100 can divert the water from both sides of the pile foundation, avoiding water flow scouring the foundation around the pile foundation and causing soil erosion, and effectively improving the stability of the pile foundation.

[0031] In some embodiments, three connecting rods 200 are provided. The three connecting rods 200 are distributed in a triangular shape on the inner side of the angle steel plate 100. Three connecting seats 311 are arranged on the first hoop 310. The three connecting seats 311 are distributed in a triangular shape on the first hoop 310.

[0032] Specifically, one end of two of the connecting rods 200 is connected to the upper part of the angle steel plate 100 through the rotating structure 400, and one end of one connecting rod 200 is connected to the lower part of one of the side plates 110 of the angle steel plate 100 through the rotating structure 400. The other ends of the three connecting rods 200 are respectively connected to the three connecting seats 311 on the first hoop 310, thus forming a triangular support structure and improving the support stability between the angle steel plate 100 and the pile foundation.

[0033] Of course, four connecting rods 200 can also be provided. The four connecting rods 200 are distributed in a rectangular shape inside the angle steel plate 100. Correspondingly, four connecting seats 311 are also arranged on the first hoop 310. The four connecting rods 200 are respectively connected to the four connecting seats 311 on the first hoop 310, so that stable support is formed between the four angle steel plates 100 and the pile foundation through the four connecting rods 200.

[0034] In some embodiments, one end of the connecting rod 200 is detachably connected to the side plate 110 of the angle steel plate 100 through a rotating structure 400. This facilitates the transportation of the angle steel plate 100, the connecting rod 200, and the hoop 300, and they can be directly assembled on site.

[0035] In order to facilitate the insertion of the angle steel plate 100 into the soil of the foundation, in some embodiments, the bottom of the angle steel plate 100 is a wedge-shaped structure 121.

[0036] In order to facilitate the adjustment of the inclination angle of the angle steel plate 100 in the foundation, in some embodiments, the connecting rod 200 is a telescopic structure. The slopes of the foundations for some pile foundation installations are all different. During the installation of the angle steel plate 100 of the present application on foundations with different slopes, it is necessary to adjust the inclination angle of the angle steel plate 100 relative to the slope surface to achieve the best water diversion effect of the angle steel plate 100. Therefore, when the inclination angle of the angle steel plate 100 is adjusted, it is necessary to adjust the length of each connecting rod 200 thereon so that each connecting rod 200 can be connected to the corresponding connecting seat 311 on the first clamp 310 to form a stable support.

[0037] In some embodiments, the connecting rod 200 includes a sleeve and a movable rod. One end of the movable rod is assembled in the sleeve, and a fastening bolt is provided on the sleeve. One end of the fastening bolt abuts against the movable rod. After the length of the connecting rod 200 is adjusted in place, tightening the fastening bolt can position the connecting rod 200.

[0038] In order to adjust the opening angle of the angle steel plate 100, in some embodiments, the angle steel plate 100 further includes a rotating shaft 120, and the two side plates 110 are rotatably connected through the rotating shaft 120. When the area of the water-facing surface of the angle steel plate 100 needs to be increased, the angles of the two side plates 110 of the angle steel plate 100 are opened wider. When the area of the water-facing surface of the angle steel plate 100 needs to be reduced, the angles of the two side plates 110 of the angle steel plate 100 are opened smaller.

[0039] In some embodiments, the rotating structure 400 includes a universal joint or a spherical connecting seat.

[0040] In the embodiment shown in the present application, the rotating structure 400 is a universal joint. Specifically, one end of the sleeve of the connecting rod 200 is installed with a universal joint, and one end of the movable rod of the connecting rod 200 is installed with a universal joint. The universal joint on the movable rod is detachably connected to the side plate 110 of the angle steel plate 100 through a bolt. The universal joint on the sleeve is detachably connected to the connecting seat 311 on the first clamp 310 through a bolt.
