Embodiment

Below, the utility model is specifically described by exemplary embodiment.It should be appreciated, however, that do not having In the case of being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations In mode.

, it is necessary to which explanation, the working face of socket end 11 refer to socket end 11 provided with recessed in description of the present utility model The side wall of groove.The orientation or position relationship of the finger such as term " interior ", " outer ", " on ", " under " are to be closed based on the position shown in accompanying drawing 1 System, it is for only for ease of and describes the utility model and simplified description, rather than the device or element of instruction or hint meaning is necessary With specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.In addition, Term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance.

As shown in figure 1, a kind of PCCP pipes socket end protective cover is the utility model is related to, in the 1 vertical storage of PCCP pipes When protect end face and the working face of its socket end 11, including the cover body 2 of socket end 11 can be covered at, cover body 2 is included in a ring Main protection department 21, main protection department 21 and the end face of socket end 11 offset；The inward flange of main protection department 21 connects oriented PCCP pipes 1 and managed First hem 22 of interior extension, the outward flange of main protection department 21 connect the second of the working face direction extension of oriented socket end 11 Hem 23.

It should be noted that the annular of the first hem 22 of cover body 2, the hem 23 of main protection department 21 and second formation one is recessed Groove, the annular groove can wrap the socket end 11 of PCCP pipes 1.Wherein, main protection department 21 is used for the end for protecting socket end 11 Face, prevent dew and rainwater from being penetrated into from the capillary gap of end face and crackle；First hem 22 is used to protect socket end 11 Inwall；Second hem 23 is used for the working face for protecting socket end 11, and it can shelter from the working face of socket end 11, avoid work The paint film for making face is destroyed.In addition it is also necessary to explanation, cover body 2, which can use, has certain degree of hardness and corrosion resistant metal material Material or plastic production, such as：Galvanized iron sheet, galvanized steel plain sheet, polytetrafluoroethylene (PTFE) etc., as long as shape can be kept, do not deformed upon, Simultaneously can be corrosion-resistant.

In a specific embodiment of the present utility model, as shown in figure 1, the width of main protection department 21 is more than the end of socket end 11 The width in face, to ensure that the protective cover can be located in the socket end 11 of PCCP pipes 1.Preferably, main protection department 21 is than inserting The wide 5cm-10cm in end face at mouth end 11.It should be noted that as main protection department 21 5cm-10cm wider than the end face of socket end 11, While cost of manufacture is saved, the first hem 22 of cover body 2 and the second hem 23 can be made slotting with PCCP pipes 1 respectively Mouth leaves certain safe distance between end 11, avoids producing friction and collision between cover body 2 and the socket end 11 of PCCP pipes 1.Can With understanding, those skilled in the art can design suitable main protection department according to the end face width of PCCP pipes socket end 11 21 width.

Further, as shown in figure 1, the height of the second hem 23 is more than the length of the working face of socket end 11, to ensure Second hem 23 can shelter from the working face of socket end 11.Preferably, work of second hem 23 than socket end 11 The high 5cm-10cm in face.It should be noted that as the second hem 23 5cm-10cm higher than the working face of socket end 11, saving While cost of manufacture, it can prevent from causing the working face of socket end 11 exposed to outer, guarantee protection effect because cover body 2 rocks Fruit.It is understood that those skilled in the art can design suitable the according to the face length of PCCP pipes socket end 11 The height of two hem 23.

As shown in figure 1, as a preferred embodiment, the first hem 22 and/or the second hem 23 and main protection department 21 are in angle Degree is set, and the angle is in the range of 90 ° -105 °.First hem 22 and the second hem 23 are so set, are more convenient for cover body 2 cover in the socket end 11 of PCCP pipes 1.

Further, since the height of PCCP pipes 1 is generally higher, for the ease of the protective cover to be covered on to the socket end of PCCP pipes 1 On 11, such as Fig. 1, the protective cover also includes hanging part 3 with hang that the suspender 5 of PCCP pipes 1 matches, and it is solid with cover body 2 to hang part 3 Fixed connection.Part 3 is hung by setting, the protective cover can be covered on to PCCP pipes 1 using the special hanger 5 for hanging PCCP pipes 1 Socket end 11 on, without setting other suspenders in addition.It should be noted that in the present embodiment, hang part 3 and specifically include cylinder Body 31, one end of cylinder 31 are fixedly connected on the main protection department 21 of cover body 2, and its other end is provided with the lug boss 32 of annular, raised Portion 32 engages matching with hanging the suspender 5 of PCCP pipes 1.In addition it is also necessary to explanation, hanging part 3 can use steel to make.

Further, deformed to prevent from hanging part 3 during hanging, as shown in Fig. 2 in cylinder 31 radially If provided with dry support arm 4.Cylinder 31 is supported by the support member 4 of setting, can avoid hanging part 3 and become during hanging Shape.

The PCCP pipe socket ends protective cover when in use, as shown in figure 3, by the suspender 5 of PCCP pipes with being hung in the protective cover The engaging matching of lug boss 32 of part 3 is put, the protective cover is covered in the socket end 11 of PCCP pipes 1 using the suspender 5 of PCCP pipes, made The main protection department 21 of cover body 2 and the end face of socket end 11 offset, and the first hem 22 stretches into PCCP pipes 1 and manages interior, the second hem 23 shelter from the working face of socket end 11.In addition, as shown in figure 4, the protective cover storage when can it is multiple up and down accumulation deposits, with Save space.

PCCP pipes socket end protective cover provided by the utility model, socket end 11 is protected by the main protection department 21 of setting End face, it can effectively prevent dew and rainwater from being penetrated into from the capillary gap of end face and crackle；Pass through the second hem of setting 23 shelter from the working face of socket end 11, can effectively protect the paint film of the working face of socket end 11, prevent socket end 11 to be corroded. Meanwhile the protective cover hangs part 3 by setting, the protective cover can be covered on using the special hanger 5 for hanging PCCP pipes 1 In the socket end 11 of PCCP pipes 1, without setting other suspenders in addition.In addition, the protective cover multiple can be accumulated up and down in storage Storage, can effectively save space.
