Technical Field

[0001] The utility model relates to the technical field of cable wiring, in particular to a cable hidden wiring structure for a distributed photovoltaic power station. Background Art

[0002] A distributed photovoltaic power station generally refers to a power generation system that utilizes decentralized resources, has a small installed capacity, and is arranged near users. It is generally connected to a power grid with a voltage level lower than 35 kV or even lower. A distributed photovoltaic power station specifically refers to a distributed photovoltaic power station system that uses photovoltaic modules to directly convert solar energy into electrical energy. Among them, household photovoltaic is a type of distributed photovoltaic. It has a small installation capacity and many installation points, and is usually installed on the roofs of residents' own houses. Cable wiring is usually required during the installation of a distributed photovoltaic power station.

[0003] However, in the prior art, it is found that during the cable wiring of a distributed photovoltaic power station, the cable is generally arranged inside a wiring pipe, but there is no measure to fix the cable inside the wiring pipe. As a result, the cable may swing inside the wiring pipe, causing friction between the cable and the inside of the wiring pipe, thereby affecting the service life of the cable.

[0004] Therefore, a cable hidden wiring structure for a distributed photovoltaic power station is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A cable hidden wiring structure for a distributed photovoltaic power station, comprising: a wiring pipe, both sides inside the wiring pipe are fixedly connected with a plurality of limiting blocks, a first limiting groove is opened on the opposite side of each of the plurality of limiting blocks, both sides inside the wiring pipe are fixedly connected with a plurality of limiting columns, two of the opposite first limiting grooves are in a group, and a cable fixing component is arranged inside each group of the first limiting grooves.

[0007] As a preferred implementation manner, a plurality of second limiting grooves are penetrated and opened on one side of the wiring pipe.

[0008] As a preferred implementation manner, the plurality of limiting columns are located inside the plurality of first limiting grooves.

[0009] As a preferred implementation manner, the cable fixing component includes an extrusion fixing block and two springs. Through holes are penetrated and opened at both ends of the extrusion fixing block. Connecting plates are fixedly connected to both sides of the extrusion fixing block. The other ends of the two connecting plates are fixedly connected with a pulling block. The surfaces of the two limiting columns are movably embedded inside the two through holes.

[0010] As a preferred embodiment, the surfaces at both ends of multiple said extrusion fixing blocks are movably embedded inside multiple first limiting grooves.

[0011] As a preferred embodiment, the surfaces of multiple said connecting plates are movably embedded inside multiple second limiting grooves.

[0012] As a preferred embodiment, multiple said springs are movably sleeved on the surfaces of multiple limiting posts, and both ends of multiple said springs are respectively connected inside the wiring pipe and on one side of multiple extrusion fixing blocks.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] In the present utility model, according to requirements, a cable wiring groove is planned and opened in a distributed photovoltaic power station, the wiring pipe is placed in the opened cable wiring groove, the cable to be wired is inserted from one end of the wiring pipe, the spring is initially in a compressed state, under the action of the spring elastic force, one side of the extrusion fixing block is closely attached to the inside of the wiring pipe. When the inserted cable encounters an obstacle at a corresponding position, the worker only needs to pull the pulling block at the corresponding position, so that both ends of the extrusion fixing block move inside the first limiting groove, and the compressed spring is deformed again under the action of pressure. The clamping block is used to block between the pulling block and the outer wall of the wiring pipe to prevent the extrusion fixing block from returning to its initial position under the action of the spring elastic force. Then the cable is inserted through the extrusion fixing block. Similarly, the cable is inserted through multiple extrusion fixing blocks until the threading of the cable is completed. The clamping block stuck between the pulling block and the outer wall of the wiring pipe is removed, so that the extrusion fixing block moves towards one side of the cable under the action of the spring elastic force, and the cable is extruded to be closely attached to the inner wall of the wiring pipe to fix the cable. Such a design avoids the cable from swinging inside the threading pipe, resulting in friction between the cable and the inside of the wiring pipe, thereby affecting the service life of the cable. At the same time, such a design is convenient for workers to operate and improves the construction efficiency; then the wiring groove is filled with cement to achieve the hidden wiring of the cable in the distributed photovoltaic power station.

[0022] 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.

[0023] See also Figures 1-5 The utility model provides a technical solution: a cable hidden wiring structure of a distributed photovoltaic power station, comprising: a wiring tube 1, multiple limit blocks 101 are fixedly connected on both sides of the wiring tube 1, and limit grooves 102 are provided on the opposite sides of the multiple limit blocks 101, multiple limit columns 103 are fixedly connected on both sides of the wiring tube 1, two opposite limit grooves 102 form a group, and cable fixing components 2 are arranged inside the multiple groups of limit grooves 102.

[0024] Specifically: when the cable encounters an obstacle when it reaches the corresponding position, the worker only needs to pull the pulling block 204 at the corresponding position to pass the cable through the squeezing and fixing block 201. Similarly, the cable is passed through multiple squeezing and fixing blocks 201 until the cable is threaded, and the block stuck between the pulling block 204 and the outer wall of the wiring tube 1 is removed, so that the squeezing and fixing block 201 moves to one side of the cable under the action of the elastic force of the spring 205, and squeezes the cable close to the inner wall of the wiring tube 1 to fix the cable. This design prevents the cable from swinging in the threading tube, causing friction between the cable and the inside of the wiring tube, thereby affecting the service life of the cable. At the same time, this design is convenient for workers to operate and improves construction efficiency; the limit block 101 is designed with an angle inclined on one side to facilitate the insertion of the cable.

[0025] In one embodiment, a plurality of limiting grooves 104 are formed through one side of the wiring tube 1 .

[0026] Specifically, the second limiting groove 104 provides a moving space for the movement of the connecting plate 203.

[0027] In one embodiment, a plurality of limiting posts 103 are located inside a plurality of first limiting grooves 102.

[0028] Specifically, the limiting post 103 provides a path for the spring 205 to be compressed or extended, preventing the spring 205 from shifting.

[0029] In one embodiment, the cable fixing assembly 2 includes a pressing and fixing block 201 and two springs 205. Through holes 202 are formed through both ends of the pressing and fixing block 201. Connecting plates 203 are fixedly connected to both sides of the pressing and fixing block 201. The other ends of the two connecting plates 203 are fixedly connected to a pulling block 204. The surfaces of the two limiting posts 103 are movably embedded inside the two through holes 202.

[0030] Specifically: When the cable being threaded reaches a corresponding position and encounters an obstruction, the worker only needs to pull the pulling block 204 at the corresponding position, so that both ends of the pressing and fixing block 201 move inside the first limiting groove 102. The compressed spring 205 is deformed again under pressure. A clamping block is used to block between the pulling block 204 and the outer wall of the wiring pipe 1, preventing the pressing and fixing block 201 from returning to its initial position under the elastic force of the spring 205; the clamping block is a hard material object that can be found randomly at the construction site, without a specific shape and material, and only prevents the pressing and fixing block 201 from returning to its initial position and hindering wire threading.

[0031] In one embodiment, the surfaces of both ends of a plurality of pressing and fixing blocks 201 are movably embedded inside a plurality of first limiting grooves 102.

[0032] Specifically: The first limiting groove 102 limits the movement of the pressing and fixing block 201.

[0033] In one embodiment, the surfaces of a plurality of connecting plates 203 are movably embedded inside a plurality of second limiting grooves 104.

[0034] Specifically: The connecting plate 203 prevents the cable from being inserted and prevents the pressing and fixing block 201 from not fixing the cable.

[0035] In one embodiment, a plurality of springs 205 are movably sleeved on the surfaces of a plurality of limiting posts 103. Both ends of the plurality of springs 205 are respectively connected to the inside of the wiring pipe 1 and one side of a plurality of pressing and fixing blocks 201.

[0036] Specifically: 103 provides a path for the spring 205 to be compressed or extended, preventing the spring 205 from shifting.

[0037] Working principle: According to requirements, cable routing grooves are planned and opened in a distributed photovoltaic power station. The wiring pipe 1 is placed in the opened cable routing grooves. The cables to be routed are inserted from one end of the wiring pipe 1. The spring 205 is initially in a compressed state. Under the action of the elastic force of the spring 205, one side of the extrusion fixing block 201 is closely attached to the inside of the wiring pipe 1. When the inserted cable encounters an obstacle at the corresponding position, the worker only needs to pull the pulling block 204 at the corresponding position, so that both ends of the extrusion fixing block 201 move inside the first limiting groove 102. The compressed spring 205 is deformed again under the action of pressure. The clamping block is used to block between the pulling block 204 and the outer wall of the wiring pipe 1 to prevent the extrusion fixing block 201 from returning to its initial position under the action of the elastic force of the spring 205. Then the cable is passed through the extrusion fixing block 201. Similarly, the cable is passed through multiple extrusion fixing blocks 201 until the cable threading is completed. The clamping block stuck between the pulling block 204 and the outer wall of the wiring pipe 1 is removed, so that the extrusion fixing block 201 moves towards the side of the cable under the action of the elastic force of the spring 205, squeezing the cable to be closely attached to the inner wall of the wiring pipe 1 to fix the cable. This design avoids the cable swinging in the threading pipe, resulting in friction between the cable and the inside of the wiring pipe, thereby affecting the service life of the cable. At the same time, this design is convenient for workers to operate and improves the construction efficiency. Then, the wiring groove is filled with cement to achieve the hidden cable routing of the distributed photovoltaic power station.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
