[0002] When photovoltaic power generation equipment is installed on the ground, hillside and other positions, it is necessary to first pour photovoltaic micro - bored piles, and then install and fix the photovoltaic support on the bored piles to ensure the stability and firmness of the whole equipment installation. When pouring the photovoltaic micro - bored piles, it is necessary to first place the metal skeleton, photovoltaic support steel pipe pile and the like fixed together into the pile pit for forming the photovoltaic micro - bored piles, and then pour concrete. And in order to ensure the compactness of the formed photovoltaic micro - bored piles, it is necessary to use an insertion vibrator to vibrate the concrete. The photovoltaic support steel pipe pile is a hollow tubular structure. When vibrating the concrete, under the action of vibration, the concrete will turn up from the bottom end of the embedded photovoltaic support steel pipe pile and enter its interior, and it is difficult to control the height of the concrete filled in each photovoltaic support steel pipe pile to be the same. In addition, the installation of photovoltaic power generation equipment is greatly affected by terrain, slope, etc., and it is often necessary to finely adjust the height of the photovoltaic support column. Generally, part of the photovoltaic support column is inserted and fixed in the photovoltaic support steel pipe pile, and its insertion length needs to be adjusted according to the terrain height to adjust the installation height of the photovoltaic support column. When the photovoltaic support steel pipe pile is filled with concrete, the downward adjustment range of the photovoltaic support column is limited. In order to ensure that its installation can meet the technical requirements, it has to be cut on site, which increases the installation workload to a certain extent, consumes unnecessary labor, and reduces the installation efficiency at the same time. Content of the Utility Model

[0005] As a preferred technical solution, the feeding plug is set as a rubber plug.

[0006] As a preferred technical solution, the feeding plug is detachably connected to the feeding vertical rod.

[0007] As a preferred technical solution, a feeding guiding surface that gradually decreases from top to bottom is provided at the lower part of the outer diameter of the feeding plug.

[0008] As an improvement to the above technical solution, the feeding vertical rod includes an outer sleeve pipe section connected to the feeding plug. An internal thread is provided on the inner wall of the outer sleeve pipe section, and an outer screw rod section is in threaded cooperation with the outer sleeve pipe section. The thread on the outer screw rod section is provided below the foot pedal rod.

It includes a feeding vertical rod. A feeding plug for blocking the lower port of the photovoltaic support steel pipe pile is connected to the lower end of the feeding vertical rod. A feeding handle is fixedly connected to the top of the feeding vertical rod. A foot pedal rod for auxiliary fixation is also fixedly connected to the feeding vertical rod below the feeding handle. The present invention has the following beneficial effects: When the photovoltaic micro - pile is poured, the feeding plug is inserted into the pre - buried photovoltaic support steel pipe pile by using the feeding vertical rod, and is pressed down through the feeding handle until the foot pedal rod is limited at the upper port of the photovoltaic support steel pipe pile. After stepping on the foot pedal rod with one foot, an insertion - type vibrator can be used to vibrate the concrete. At this time, the feeding plug blocks the lower port of the photovoltaic support steel pipe pile, preventing the concrete from turning up into the photovoltaic support steel pipe pile during vibration. After vibration and compaction, only the whole device needs to be pulled out. The operation is convenient and fast, reducing unnecessary cutting work of the photovoltaic support columns and helping to ensure the construction efficiency of the photovoltaic support.

[0015] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0016] Embodiment 1:

[0017] As Figure 1 and Figure 2 shown, the concrete anti - upwelling device for the photovoltaic support steel pipe pile is inserted into the photovoltaic support steel pipe pile 1 during use. When using a plug - in vibrator to vibrate the concrete for forming the photovoltaic microporous cast - in - place pile 2, it seals the lower port of the photovoltaic support steel pipe pile 1 to prevent the concrete from turning up under the action of vibration and entering the photovoltaic support steel pipe pile 1, blocking its lumen, thus affecting the downward adjustment space of its column when installing the photovoltaic support. The concrete anti - upwelling device for the photovoltaic support steel pipe pile specifically includes a feeding vertical rod 3. The lower end of the feeding vertical rod 3 is connected with a feeding plug 4 for sealing the lower port of the photovoltaic support steel pipe pile 1. The top end of the feeding vertical rod 3 is fixedly connected with a feeding handle 5. A foot pedal rod 6 for auxiliary fixation is also fixedly connected to the feeding vertical rod 3 below the feeding handle 5. During use, align the feeding plug 4 with the upper port of the photovoltaic support steel pipe pile 1, and use the cooperation of the feeding vertical rod 3 and the feeding handle 5 to send the feeding plug 4 downward into the photovoltaic support steel pipe pile 1 until the feeding plug 4 seals the lower port of the photovoltaic support steel pipe pile 1.

[0018] As Figure 2 shown, before forming the photovoltaic microporous cast - in - place pile 2, it is necessary to first place the metal skeleton 7, the photovoltaic support steel pipe pile 1, etc. fixed together into the pile pit for forming the photovoltaic microporous cast - in - place pile 2. With the help of the metal skeleton 7, the photovoltaic support steel pipe pile 1 is held in place. After they are placed, a part of the photovoltaic support steel pipe pile 1 extends outside the pile pit for forming the photovoltaic microporous cast - in - place pile 2. The photovoltaic microporous cast - in - place pile 2 also has a part extending outside the pile pit, and the upward extension length of the photovoltaic support steel pipe pile 1 is greater than the upward extension length of the photovoltaic microporous cast - in - place pile 2, that is, the upper end of the photovoltaic support steel pipe pile 1 is higher than the upper end of the photovoltaic microporous cast - in - place pile 2. The part of the photovoltaic microporous cast - in - place pile 2 extending upward is specifically realized by a short pipe 8 or a short cylinder sleeved on the outer periphery of the photovoltaic support steel pipe pile 1. As Figure 2Among them, the ground elevation is at the position of H1, and the elevation of the photovoltaic micropile 2 is at the position of H2. The part of the photovoltaic micropile 2 between H1 and H2 is realized through the short pipe 8.

[0019] During use, when the feeding plug 4 is blocked at the lower port of the photovoltaic support steel pipe pile 1 by using the feeding handle 5 and the feeding vertical rod 3, the foot pedal rod 6 is just limited and supported at its top. The thickness of the feeding plug 4 and its distance from the foot pedal rod 6 can be customized according to the length of the photovoltaic support steel pipe pile 1 to be blocked, so that the whole device can just match and use with the photovoltaic support steel pipe pile 1. After inserting this embodiment into the photovoltaic support steel pipe pile 1, the person vibrating the concrete steps on the foot pedal rod 6 with one foot to fix it at the top of the photovoltaic support steel pipe pile 1 to bear the vibration force generated during vibration. Thus, one person can complete the tasks of vibration and blocking of the photovoltaic support steel pipe pile 1, and the use is simple and convenient. After the vibration operation is completed, the whole device can be pulled out and moved to the next operation point for use.

[0020] The feeding plug 4 is set as a rubber plug, which has a certain elasticity, so that its contact with the photovoltaic support steel pipe pile 1 is relatively tight, and the plugging effect on its port is good, indirectly improving the effect of suppressing the upward slurry in the pipe pile. The feeding plug 4 and the feeding vertical rod 3 are detachably connected, so as to facilitate replacing the corresponding matching feeding plug 4 according to the pipe diameter of the photovoltaic support steel pipe pile 1, making the use flexibility of this embodiment better.

[0021] Embodiment 2:

[0022] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is that: a feeding guiding surface 9 that gradually decreases from top to bottom is provided at the lower part of the outer diameter of the feeding plug 4. To ensure a good plugging effect of the feeding plug 4 on the photovoltaic support steel pipe pile 1, the outer diameter of the feeding plug 4 can be slightly larger than the inner diameter of the photovoltaic support steel pipe pile 1. With the help of the easy deformation characteristic of the rubber material of the feeding plug 4, the assembly of the feeding plug 4 and the photovoltaic support steel pipe pile 1 can be quickly realized under the cooperation of the feeding guiding surface 9.

[0023] Another difference between this embodiment and the first embodiment lies in the adjustable length of the feeding vertical rod 3. Specifically, the feeding vertical rod 3 includes an outer sleeve section 31 connected to the feeding plug 4. An internal thread is provided on the inner wall of the outer sleeve section 31, and an external screw rod section 32 is in threaded cooperation with the outer sleeve section 31. The thread on the external screw rod section 32 is arranged below the foot lever 6. Through the threaded cooperation between the outer sleeve section 31 and the external screw rod section 32, the distance between the feeding plug 4 and the foot lever 6 is adjusted to meet the plugging requirements of the photovoltaic support steel pipe piles 1 of different lengths, further improving the flexibility of use and making the adjustment simple and convenient.
