[0002] Cable laying is a common task during the transformation of the lower computer of the monitoring system of a hydro-turbine generator set. There are different cable laying requirements in various technical transformation projects. The progress of cable arrangement after cable laying directly determines the overall progress of the project.

[0003] In the lower computer transformation project of the existing power plant monitoring system, it is necessary to dismantle the original old cabinets and return the old cables, put the new cabinets in place and complete the wiring of the new cables in the cabinets. Due to the large number of cables and the narrow cable holes, it is extremely difficult to comb them. The traditional method is to use insulating tape to stick insulation protection on each core wire head in each cable. For the same newly pulled control cable, it is necessary to check whether the core is correct on both sides of each cable. Before checking each core wire, the previously pasted insulating tape must be removed again. This process consumes a lot of time and energy, seriously affecting the overall work progress of the transformation project and is inefficient. Utility Model Content

[0023] like Figure 1 As shown, it shows a specific implementation mode of the utility model: the utility model discloses a new type of cable head protective cover, including a first protective cover 1, a second protective cover 2, a third protective cover 3, and a marking cover 4. The top of the first protective cover 1 is connected to the bottom end of the second protective cover 2, the top of the second protective cover 2 is connected to the bottom end of the third protective cover 3, and the marking cover 4 is connected to the top of the third protective cover 3. The diameter of the bottom end of the first protective cover 1 is smaller than the diameter of a single core wire of the cable, the diameters of the top end of the first protective cover 1 and the bottom end of the second protective cover 2 are larger than the diameter of a single core wire of the cable, the diameters of the top end of the second protective cover 2 and the bottom end of the third protective cover 3 are smaller than the diameter of the bottom end of the second protective cover 2, and the diameter of the marking cover 4 is larger than the diameter of a single core wire of the cable.

[0024] The first protective cover 1, the second protective cover 2, and the third protective cover 3 are all made of PVC material, the first protective cover 1 is an elastic material, and the second protective cover 2 and the third protective cover 3 are hard materials.

[0025] In the utility model, the first protective cover 1 is made of elastic material, which can smoothly insert and wrap the label end of the cable to prevent the cable head protective cover from falling off under the action of external force, which is reliable and effective. The second protective cover 2 and the third protective cover 3 can protect the label of the cable head and the exposed part of the wire to ensure the effectiveness of the cable when it is connected again. The marking cover 4 is convenient for the operator to mark and improves the work efficiency of checking the line quantity of new and old cables, thereby reducing the overall work cycle of the renovation project and greatly improving work efficiency.

[0026] Embodiment 1

[0027] Preferably, the first protective cover 1, the second protective cover 2, the third protective cover 3 and the marking cover 4 are of integrated design.

[0028] Preferably, a tear strip opening is designed at the connection between the second protective cover and the first protective cover 1 , and the tear strip is designed along the outer surface of the first protective cover 1 .

[0029] In the utility model, the cable head protective cover adopts an integrated design, which can ensure that the cable head is completely, effectively and reliably wrapped. It is marked by the marking cover 4, which is also convenient for checking the line pair of new and old cables in the later stage. The integrated design requires the protective cover to be torn off for reconnection. The opening of the easy-tear strip on the first protective cover 1 and the design of the easy-tear strip can be quickly torn off to complete the relevant connection. Compared with the traditional method of using insulating tape to stick and tear it off, it greatly improves work efficiency and reduces labor intensity.

[0030] Preferably, it further comprises an auxiliary expansion clip, wherein two sides of the auxiliary expansion clip are designed to be arc-shaped.

[0031] In the utility model, when this embodiment is used, the first protective cover 1 is stretched open by an auxiliary expansion clamp, and the opening size is sufficient to cover the position where the cable head is to be covered, and the protective cover is covered and wrapped firmly. In this way, on the basis that the bottom end diameter of the first protective cover 1 is smaller than the diameter of a single core wire of the cable head, it can be conveniently covered, and the label end on the core wire can be firmly covered for protection, thereby improving work efficiency.

[0032] Embodiment 2

[0033] Preferably, the first protective cover 1 and the second protective cover 2 are of split design, the first protective cover 1 is designed with a fixing ring at the top, the second protective cover 2 is designed with a first locking protrusion at the bottom, the first locking protrusion can be fixed on the fixing ring of the first protective cover 1, the third protective cover 3 is fixedly connected to the top of the second protective cover 2, the top of the third protective cover 3 is designed with a groove, the lower end of the marking cover 4 is designed with a second locking protrusion, the groove is adapted to the second locking protrusion.

[0034] In the present invention, the first protective cover 1 and the second protective cover 2 are of split design, and the first protective cover 1 is conveniently put into the cable label end through the fixing ring on the first protective cover 1. First, the bottom end of the first protective cover is rolled up, and the fixing ring is placed in the position of the exposed conductive end of the core wire of the cable head. Then, the first protective cover 1 is slid down along the cable end to achieve the insertion, so as to prevent the cable head protective cover from falling off under the action of external force. This is reliable and effective. The first protective cover 1 and the second protective cover 2 are stably connected by the first clamping protrusion on the fixing ring, and the third protective cover 3 and the marking cover 4 are stably connected by the second clamping protrusion on the groove. This method can conveniently complete the protection of the cable head and improve work efficiency.

[0035] Preferably, the second protective cover 2 is made of a transparent material, and its length is greater than the length of the label of the wrapped cable.

[0036] In the utility model, this embodiment conveniently extracts cable information through the data in the second protective cover 2 under the transparent material when in use. When reconnecting, there is no need to tear off the protective cover. Only the first protective cover 1 and the second protective cover 2 need to be removed through the first clamping protrusion, which reduces the operation process, improves work efficiency, and ensures effective protection of the cable.

[0037] Preferably, the length of the third protective cover 3 is greater than the length of the exposed wire at the interface of the wrapped cable.

[0038] In the present invention, the length of the third protective cover 3 is set to be greater than the length of the wire exposed at the interface, so as to effectively protect the wire.
