Description

Technical Field

[0001] The utility model relates to the technical field of generator outgoing lines, and particularly relates to a cable anti-wear device for a generator outgoing line opening. Background Art

[0002] In the prior art, only a U-shaped iron ring with rubber attached to the surface is clamped around the iron sheet at the generator outgoing line opening. Although the iron ring with rubber attached to the surface can increase the surface area of the iron sheet at the outgoing line opening and reduce the pressure between the cable and the iron sheet, due to the vibration of the generator set, friction will occur between the cable insulation layer and the iron ring. After the generator set runs for a long time, the cable insulation layer will be worn through, resulting in a short circuit and damage to the equipment, which poses a great potential safety hazard. Content of the Utility Model

[0003] The utility model provides a cable anti-wear device for a generator outgoing line opening to solve the problems in the prior art.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A cable anti-wear device for a generator outgoing line opening includes a front panel and a rear panel. A contact groove is provided at the circumferential position of the docking part of the front panel and the rear panel. The contact groove cooperates with the generator outgoing line hole, and the front panel and the rear panel are connected by a front-rear fixing mechanism to fasten the front panel and the rear panel at the position of the generator outgoing line hole.

[0006] Both the front panel and the rear panel are composed of multiple modules arranged vertically. The modules are fixedly connected by an up-down fixing mechanism.

[0007] One or more outgoing line holes arranged horizontally are provided between two adjacent upper and lower modules. Each outgoing line hole is composed of two upper and lower outgoing line half-holes, and the two upper and lower outgoing line half-holes are respectively located on two adjacent upper and lower modules.

[0008] Preferably, the front and rear ends of the outgoing line hole are respectively set as bell mouths, and the outgoing line hole is a straight channel between the two bell mouths, and the straight channel is smoothly connected to the bell mouths.

[0009] Preferably, it further includes a diameter-changing structure that cooperates with the outgoing line hole. The diameter-changing mechanism includes a diameter-changing sleeve. The outer diameter of the diameter-changing sleeve is adapted to the outgoing line hole, and the inner diameter of the diameter-changing sleeve is an outgoing line hole that is proportionally reduced.

[0010] Preferably, the diameter-changing sleeve is composed of two upper and lower diameter-changing half-sleeves, and the two diameter-changing half-sleeves are respectively adapted to the two outgoing line half-holes.

[0011] Preferably, it further includes a blocking mechanism that cooperates with the outgoing line opening. The outgoing line holes through which no cables pass are closed by the blocking mechanism.

[0012] Preferably, the blocking mechanism is a cylindrical plug that cooperates with the straight channel of the outgoing line hole.

[0013] Preferably, a U-shaped iron ring is provided around the position of the generator outgoing line hole, and the contact groove has a shape matching the U-shaped iron ring.

[0014] Preferably, the module includes a bottom module, a top module, and one or more intermediate modules located between the top module and the bottom module.

[0015] Preferably, the front and rear fixing mechanism includes front and rear fixing bolts extending in the front and rear directions.

[0017] Advantages of the utility model:

[0018] 1. The utility model can clamp the cable to avoid shaking and friction. At the same time, it increases the contact area between the generator outgoing line port and the cable, reduces the pressure, protects the cable, prevents the cable insulation layer from being damaged, and reduces potential safety hazards; it also increases the sealing performance of the generator, reduces the entry of oil stains and dust into the generator interior, and protects the generator; it reduces the high-frequency vibration of the generator cable and reduces the dropping of the connection bolts of the cable due to vibration.

[0019] 2. The front and rear ends of the outgoing line hole of the utility model are respectively provided as bell mouths. Due to gravity, the cable naturally sags and contacts the bell mouths, increasing the contact surface and reducing the pressure to protect the cable.

[0020] The outgoing line hole of the utility model is a straight channel between the two bell mouths. After the module and the cable are fixed, the module closely adheres to the generator outgoing line hole, and at the same time, the straight channel closely adheres to the cable, reducing the friction between the outgoing line hole and the cable.

[0021] 3. Since the thicknesses of the outgoing cables are different, a suitable diameter-changing mechanism can be made according to requirements and placed into the outgoing line hole of the main device, which can reduce the diameter of the outgoing line port to adapt to cables of different thicknesses.

[0022] 4. Since the number of outgoing cables may be other numbers, a plugging mechanism is designed. The plugging mechanism can be placed into the outgoing line hole of the main device to plug the idle (not passing through the cable) outgoing line holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The attached drawings are only for illustrative purposes and should not be construed as a limitation of this patent; for better illustrating this embodiment, some components in the attached drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted. Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. The hole surface of the wire outlet hole is shown in the hatched part in the figure.

[0032] As Figures 1 to 7 shown, this embodiment provides a cable anti-wear device for the generator wire outlet, including a front panel 10 and a rear panel 20. A contact groove 30 is provided at the circumferential position of the butt joint of the front panel 10 and the rear panel 20, and the contact groove 30 cooperates with the generator wire outlet hole. In this embodiment, a U-shaped iron ring is provided around the generator wire outlet hole, and the contact groove 30 is in a shape that cooperates with the U-shaped iron ring.

[0033] At the same time, the front panel 10 and the rear panel 20 are connected by a front-back fixing mechanism to fasten the front panel 10 and the rear panel 20 at the generator wire outlet hole position.

[0034] Both the front panel 10 and the rear panel 20 are composed of a plurality of modules arranged up and down, and the modules are fixedly connected by an up-down fixing mechanism. The modules are made of nylon material.

[0035] The module includes a bottom module 1, a top module 3, and an intermediate module 2 located between the top module 1 and the bottom module. The number of intermediate modules 2 can be increased according to needs, so as to increase the number of wire outlet holes.

[0036] In this embodiment, the front-back fixing mechanism includes a front-back fixing bolt 40 extending in the front-back direction. The front-back fixing bolt 40 passes through the corresponding front and rear modules, and a nut cooperating with the front-back fixing bolt is embedded in one of the modules.

[0037] In this embodiment, the up-and-down fixing mechanism includes an up-and-down fixing bolt 50 extending in the up-and-down direction. The up-and-down fixing bolt 50 passes through the corresponding modules in the up-and-down direction, and a nut cooperating with the up-and-down fixing bolt 50 is embedded in the bottom module.

[0038] A plurality of wire outlet holes 4 arranged left and right are provided between two adjacent upper and lower modules. Each wire outlet hole 4 is composed of two upper and lower wire outlet half-holes, and the two upper and lower wire outlet half-holes are respectively located on two adjacent upper and lower modules.

[0039] In this embodiment, the front and rear ends of the wire outlet hole 4 are respectively provided as flared mouths 5. The wire outlet hole 4 is a straight channel 6 between the two flared mouths 5, and the straight channel 6 is smoothly connected to the flared mouths 5. Due to gravity, the cable naturally sags and contacts the flared mouths 5, increasing the contact surface, reducing the pressure, and protecting the cable.

[0040] Since the thicknesses of the outgoing cables are different, a suitable diameter-changing mechanism can be made according to requirements and placed in the wire outlet hole of the main device, which can reduce the diameter of the wire outlet to adapt to cables of different thicknesses.

[0041] Specifically, the diameter-changing mechanism includes a diameter-changing sleeve 7. The diameter-changing sleeve 7 is composed of two upper and lower diameter-changing half-sleeves, and the two diameter-changing half-sleeves are respectively matched with the two wire outlet half-holes. The outer diameter of the diameter-changing sleeve 7 is adapted to the wire outlet hole, and the inner diameter of the diameter-changing sleeve 7 is a wire outlet hole with an equal-proportion reduction.

[0042] Since the number of outgoing cables may be other numbers, a plugging mechanism is designed. The plugging mechanism can be placed in the wire outlet hole of the main device and is used to plug the idle (without passing cables) wire outlet holes.

[0043] Specifically, the plugging mechanism is a cylindrical plug 8 cooperating with the straight channel 6 of the wire outlet hole 4.

[0044] The combination process and working principle of the present utility model are as follows:

[0045] The overall device is composed of six modules made of nylon material and can be 3D printed (the middle module can be added according to requirements to increase the number of wire outlet holes).

[0046] During installation, first install the bottom module 1, align the contact groove 30 with the U-shaped iron ring of the generator wire outlet hole, fix the six front and rear fixing bolts 40 of the bottom module 1, then put the cable into the wire outlet hole of the bottom module 1, and then install the middle module 2. Slightly fix the six front and rear fixing bolts 40 of the middle module 2 to make it movable up and down, then put the cable into the wire outlet hole of the middle module 2, and then install the upper module 3. Slightly fix the six front and rear fixing bolts 40 inside and outside the upper module 3. After arranging and installing, fix the up-and-down fixing bolt 50 of the module, and tighten the bolts of the front and rear fixing bolts 40 and the up-and-down fixing bolt 50 back and forth in turn.

[0047] After the module and the cable are fixed, the module can be closely attached to the generator outlet or the cable, reducing the friction between the outlet and the cable. Due to gravity, the cable naturally sags and contacts the module bell mouth, increasing the contact area and reducing the pressure to protect the cable.

[0048] The application of the present utility model increases the contact area between the generator outlet and the cable insulation layer, reduces the pressure, protects the cable, prevents damage to the cable insulation layer, and reduces potential safety hazards.

[0049] The application of the present utility model increases the sealing performance of the generator, reduces the entry of oil stains and dust into the generator through the outlet, and protects the generator.

[0050] The application of the present utility model reduces the high-frequency vibration of the generator cable and reduces the dropping of the connection bolts of the cable due to vibration.
