Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a fault handling device for photovoltaic power plants. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy, employs specialized materials such as crystalline silicon panels, inverters, and other electronic components, and connects to the power grid to transmit electricity. It can be divided into stand-alone power generation systems with batteries and grid-connected power generation systems without batteries. However, cables are indispensable for the normal operation of a PV power station. During use, cables may suffer damage to their sheaths due to internal or external factors. Timely repair is necessary to ensure the normal operation of the PV power station and to resolve any malfunctions. Therefore, designing a device capable of repairing cable sheaths is crucial. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fault handling device for photovoltaic power plants. Its advantage is that it can repair the outer sheath of cables located at high altitudes, ensuring the operation of the photovoltaic power plant.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fault handling device for a photovoltaic power station includes a notched bearing housing and a notched rotating cavity rotatably connected to the notched bearing housing. Notched gear rings are fixedly connected to both ends of the rotating cavity, and the two notched gear rings are in contact with both ends of the notched bearing housing. Paint spraying chambers are fixedly connected to the front and rear sides of both ends of the notched rotating cavity.

[0006] Furthermore, a dual-head motor I is fixedly connected to both the front and rear ends of the notched bearing housing, and a linkage gear is fixedly connected to the two output shafts of the two dual-head motors I. The two sets of linkage gears are respectively meshed and connected to the two notched gear rings for transmission.

[0007] Furthermore, the notched bearing seat is fixedly connected to the bottom bearing seat, two contact rollers are rotatably connected to the bottom bearing seat, four threaded rods are fixedly connected to the bottom bearing seat, a top bearing seat is slidably connected to the four threaded rods, two drive rollers are rotatably connected to the top bearing seat, and fastening nuts are threadedly connected to each of the four threaded rods.

[0008] Furthermore, each of the four threaded rods is fixedly connected with a limiting ring, and all four limiting rings are located below the top bearing seat.

[0009] Furthermore, both ends of the two driving rollers are fixedly connected to a transmission sprocket I.

[0010] Furthermore, a dual-head motor II is fixedly connected to the top bearing housing, and a transmission sprocket II is fixedly connected to each of the two output shafts of the dual-head motor II. The two transmission sprockets I and II located on the same side are connected in a transmission connection.

[0011] Furthermore, balance support plates are fixedly connected to both the front and rear ends of the bottom bearing seat.

[0012] Furthermore, a collection bucket is fixedly connected to both of the aforementioned balance support plates.

[0013] Furthermore, both collection buckets are slidably connected to a sealing cover.

[0014] Furthermore, each of the two sealing sliding covers is fixedly connected with a handle.

[0015] The beneficial effects of this utility model are as follows:

[0016] Liquid rubber is stored in four coating spray chambers. The cable is then passed through the notched bearing housing, the notched rotating chamber, and the notches above the two notched toothed rings. When it reaches the damaged area of ​​the cable, the two notched toothed rings drive the notched rotating chamber to rotate. At this time, the four coating spray chambers will rotate around the cable, activating the extrusion function of the four coating spray chambers. The liquid rubber will then be sprayed out, thus acting on the damaged area of ​​the cable to complete the repair treatment and ensure the normal operation of the photovoltaic power station.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0029] like Figure 1-4 As shown:

[0030] A fault handling device for a photovoltaic power station includes a notched bearing housing 101 and a notched rotating cavity 102 rotatably connected to the notched bearing housing 101. Notched gear rings 103 are fixedly connected to both ends of the rotating cavity 102. The two notched gear rings 103 are in contact with both ends of the notched bearing housing 101 respectively. Paint spraying cavities 104 are fixedly connected to the front and rear sides of both ends of the notched rotating cavity 102.

[0031] Furthermore, the notched bearing housing 101 provides rotational space for the notched rotating cavity 102, and the two notched gear rings 103 can limit the notched rotating cavity 102, allowing it to rotate only. Moreover, the two notched gear rings 103 can also drive the notched rotating cavity 102 to rotate. The notched rotating cavity 102 provides fixed space for the four paint spraying cavities 104. Each of the four paint spraying cavities 104 stores liquid rubber and is equipped with a fully automatic extrusion function. When it is necessary to spray out the liquid rubber in the four paint spraying cavities 104, simply activate the extrusion function. The liquid rubber in the four paint spraying cavities 104 will be sprayed out and applied to the damaged area of ​​the cable sheath.

[0032] Liquid rubber is stored in four coating spray chambers 104. The cable is then passed through the notched bearing seat 101, the notched rotating chamber 102, and the notches above the two notched toothed rings 103. When the cable reaches the damaged area, the two notched toothed rings 103 drive the notched rotating chamber 102 to rotate. At this time, the four coating spray chambers 104 will rotate around the cable, activating the extrusion function of the four coating spray chambers 104. The liquid rubber will then be sprayed out and applied to the damaged area of ​​the cable, completing the repair treatment of the damaged area and ensuring the normal operation of the photovoltaic power station.

[0033] like Figure 1-3 As shown:

[0034] Both ends of the notched bearing housing 101 are fixedly connected to a dual-head motor I201. The two output shafts of the two dual-head motors I201 are fixedly connected to a linkage gear 202. The two sets of linkage gears 202 are respectively meshed and connected to the two notched gear rings 103 for transmission.

[0035] Furthermore, the dual-head motor I201 has a built-in battery and can be remotely controlled. After starting both dual-head motors I201, they can drive two sets of two linkage gears 202 to rotate. When the two sets of two linkage gears 202 rotate, they can drive the two notched gear rings 103 to rotate. Because the notched gear rings 103 have notches, if only one dual-head motor I201 is designed, there will be a power shortage. With two dual-head motors I201, at most only the two linkage gears 202 on one dual-head motor I201 will disengage from the two notched gear rings 103, while the other dual-head motor I201 will also drive the two notched gear rings 103 to rotate through its two linkage gears 202, ensuring that the two notched gear rings 103 can rotate smoothly, thereby driving the notched rotating cavity 102 to rotate around the cable, ensuring that the four paint spraying cavities 104 can repair the damaged parts of the cable.

[0036] like Figure 1 and 4 As shown in -6:

[0037] The notched bearing seat 101 is fixedly connected to the bottom bearing seat 301. Two contact rollers 302 are rotatably connected to the bottom bearing seat 301. Four threaded rods 303 are fixedly connected to the bottom bearing seat 301. A top bearing seat 304 is slidably connected to the four threaded rods 303. Two drive rollers 305 are rotatably connected to the top bearing seat 304. Each of the four threaded rods 303 is threadedly connected to a fastening nut 306.

[0038] Furthermore, the bottom bearing housing 301 serves as a load-bearing connection, providing rotational space for the two contact rollers 302 and fixing space for the four threaded rods 303. Both contact rollers 302 are provided with grooves, and the cable will be located in the grooves of the two contact rollers 302. The four threaded rods 303 provide sliding space for the top bearing housing 304, and the top bearing housing 304 provides rotational space for the two drive rollers 305. The two drive rollers 305 are also provided with grooves, and the cable is located in the grooves of the two drive rollers 305. The top bearing housing 304 can be limited by the four fastening nuts 306.

[0039] The cable is passed through the notched bearing housing 101, the notched rotating cavity 102, and the notches above the two notched gear rings 103. At this time, the lower part of the cable will contact the two contact rollers 302 and be located in their grooves. Then, the top bearing housing 304 is slidably connected to the four threaded rods 303, and then the four fastening nuts 306 are connected to the four threaded rods 303 to fix the top bearing housing 304. At this time, the upper part of the cable will contact the two driving rollers 305 and be located in their grooves. When the two driving rollers 305 rotate, they will drive the device to move on the cable. When the cable is damaged, the rotation stops and the damaged part of the cable is repaired.

[0040] like Figure 1 , 4 As shown in Figure 6:

[0041] Each of the four threaded rods 303 is fixedly connected to a limiting ring 401, and all four limiting rings 401 are located below the top bearing seat 304.

[0042] Furthermore, the four limiting rings 401 limit the height of the top bearing seat 304 to prevent it from falling excessively. If the top bearing seat 304 falls excessively, it will squeeze the cable between the two contact rollers 302 and the two drive rollers 305, making the device unable to move on the cable.

[0043] like Figure 1 , 4 As shown in Figure 5:

[0044] Both ends of the two active rollers 305 are fixedly connected to transmission sprockets I501. The two sets of two transmission sprockets I501 drive the two active rollers 305 to rotate. When the two active rollers 305 rotate, the device will move on the cable to treat the damaged insulation of the high-altitude cable.

[0045] like Figure 1 , 4 As shown in Figure 5:

[0046] A dual-head motor II601 is fixedly connected to the top bearing seat 304. A transmission sprocket II602 is fixedly connected to each of the two output shafts of the dual-head motor II601. The two transmission sprockets I501 and II602 located on the same side are connected in a transmission connection.

[0047] Furthermore, the dual-head motor II601 has a built-in battery and can be remotely controlled. After starting the dual-head motor II601, it can drive the two transmission sprockets II602 to rotate. The rotating transmission sprockets II602 will drive the two sets of two transmission sprockets I501 to rotate, ultimately completing the long-distance movement of the device over the cable.

[0048] like Figure 1 , 4 As shown in 6 and 7:

[0049] The bottom bearing seat 301 is fixedly connected to both the front and rear ends with balance support plates 701.

[0050] Furthermore, because the device moves at high altitudes and has a very small contact area, it is prone to tilting, which will affect its movement. By installing two balance plates 701, the stability of the device can be increased, ensuring its normal operation.

[0051] like Figure 1 , 4 As shown in 6 and 7:

[0052] A collection bucket 801 is fixedly connected to each of the two balance support plates 701.

[0053] Furthermore, the two collection buckets 801 act as counterweights. Adding weights to the two collection buckets 801 will result in better stability, further improve the efficiency of the device's movement, and ensure that the device can move over long distances to repair longer cables.

[0054] like Figure 1 , 4 As shown in 6 and 7:

[0055] Both collection buckets 801 are slidably connected to a sealing cover 901.

[0056] Furthermore, the installation of the sealing sliding cover 901 prevents debris from entering the two collection bins 801. If the counterweights of the two collection bins 801 are not consistent, it will cause the device to tilt and affect the stability of the device.

[0057] like Figure 1 , 4 As shown in 6 and 7:

[0058] Each of the two sealing sliding covers 901 is fixedly connected with a handle.

[0059] Furthermore, the addition of handles makes it easy to remove the two sealing covers (901).

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
