Description

Technical Field

[0001] The utility model relates to the technical field of bolts, and in particular to a pre-buried anchor photovoltaic bolt with a stone foundation. Background Art

[0002] The photovoltaic power generation system mainly uses lenses to focus sunlight onto concentrated photovoltaic cell chips to achieve the purpose of power generation. That is, the entire photovoltaic power generation system must rotate with the movement of the sun, so the photovoltaic power generation system must be supported by pillars.

[0003] At present, the photovoltaic power generation systems built are generally located in relatively plain areas. The foundation is generally composed of materials such as soil, stone or sand. Anchor bolts are generally used to install the supporting structure of the photovoltaic power generation system on the foundation.

[0004] For example, the prior art Chinese patent publication number "CN106015255A" provides a concentrated photovoltaic pre-embedded anchor bolt with a stone foundation, including a pre-embedded anchor bolt body and a pre-embedded anchor bolt thread, wherein the pre-embedded anchor bolt body and the pre-embedded anchor bolt thread are longitudinally connected together.

[0005] The device makes good use of the stone foundation in mountainous areas and other regions to directly fix the embedded anchor bolt body inside the stone. The embedded anchor bolt thread is directly connected to the concentrated photovoltaic column bracket. In addition, based on the use of cheap mountain land rent or sales money, the material and construction costs of the entire concentrated photovoltaic power generation system are greatly reduced, thereby achieving the purpose of reducing power generation costs.

[0006] The existing foundation is a stone pre-embedded anchor photovoltaic bolt. The bolts are easy to fall over after placement and are not convenient to be set vertically in the stone foundation, which affects the connection and use of the photovoltaic equipment. At the same time, the bolts are pre-embedded in the stone foundation, and dust and impurities will adhere to their surface, which will cause greater friction and wear between the nuts and bolts connected to the bolts during rotation, and they cannot be cleaned. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art that the bolts are easy to fall over after being placed and are not convenient to be set vertically in the stone foundation, thus affecting the accuracy of connection and use of photovoltaic equipment, and a pre-buried foundation photovoltaic bolt with a stone foundation is proposed.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A pre-buried anchor photovoltaic bolt with a stone foundation is designed, comprising a screw rod, a reinforcement rod is fixed to the bottom end of the screw rod, a connecting hole is opened in the middle of the reinforcement rod, a balance rod passes through the inside of the connecting hole, a first nut is connected to the surface of the balance rod and at both ends of the connecting hole, rubber rings are sleeved on both ends of the balance rod, a thread is provided on the surface of the screw rod, a second nut is connected to the surface of the screw rod, cleaning rings are bonded to both sides of the second nut, a positioning column is fixed to the inner side of the cleaning ring, positioning grooves are opened on both sides of the second nut, and the positioning column is inserted into the positioning grooves.

[0010] Furthermore, a cleaning brush is fixed on the inner surface of the cleaning ring, the cleaning brush is made of elastic rubber material, and the cleaning brush is inserted into the groove of the thread.

[0011] Furthermore, the reinforcement rod is an arc-shaped structure, and the balance rod is a threaded rod structure and is perpendicular to the reinforcement rod.

[0012] Furthermore, the balancing rod is detachably fastened and installed to the reinforcement rod via the first nut.

[0013] Furthermore, the rubber ring is a circular ring structure, is vertically arranged, and is detachably connected to the balance pole.

[0014] Furthermore, the cleaning ring is of annular structure and is made of elastic rubber material and is sleeved on the surface of the screw.

[0015] The utility model provides a pre-buried photovoltaic bolt with a stone foundation, which has the following beneficial effects:

[0016] 1. The reinforcing rod of the utility model is fixed at the bottom end of the screw rod, and the balancing rod can be detachably slidably installed through the connecting hole, and rubber rings are sleeved on both ends of the balancing rod. In this way, during the process of pre-embedding the anchor bolts, the reinforcing rod can be kept horizontally set by the balancing rod and the rubber rings at both ends, so that the bolts can be vertically pre-embedded in the stone foundation without tilting, thereby facilitating the connection of the photovoltaic equipment.

[0017] 2. The utility model has cleaning rings bonded on both sides of the second nut connected to the screw rod, which are sleeved on the surface of the screw rod, and a cleaning brush fixed inside the cleaning ring is inserted into the groove of the thread. In this way, during the use of the anchor photovoltaic bolt, when the second nut is rotated, the cleaning ring and the cleaning brush will brush and clean the surface of the screw rod and the groove of the thread in advance to remove dust and impurities, thereby reducing the friction and wear between the second nut and the screw rod.
