Description

Technical Field

[0001] The present invention relates to the technical field of cable fixing, and in particular to an integrated device for fixing and protecting high-voltage cable incoming lines in a transformer substation. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of conductors, and most cables in my country are installed in the air for power transmission;

[0003] Box-type substation, also known as prefabricated substation or prefabricated substation, is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, and movable steel structure box.

[0004] At present, the existing substation high-voltage cable incoming line fixed protection integrated device can only fix the cable when in use. However, when the cable is in use, one part is located outside the substation and the other part is located inside the substation. Therefore, when the cable outside the substation is shaken by external force, the force of the cable shaking is transmitted to the cable connection, causing vibration and friction between the cable and the substation, which is easy to damage the cable after long-term use. Secondly, when the existing substation high-voltage cable incoming line fixed protection integrated device is in use, due to the different thickness of the cable, it is necessary to select a fixing device with different inner diameter to fix the cable. For this reason, we propose a substation high-voltage cable incoming line fixed protection integrated device. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides an integrated device for fixing and protecting high-voltage cable incoming lines in a substation, which solves the technical problems existing in the above-mentioned background technology.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A substation high-voltage cable incoming line fixed protection integrated device, the device comprising:

[0010] An inner plate and an outer plate parallel to each other, a protective plate and an extrusion plate respectively mounted on opposite sides of the inner plate and the outer plate, and a mounting plate disposed between the protective plate and the extrusion plate, the mounting plate being connected to the protective plate and the extrusion plate respectively via slide rails; and

[0011] A fixing assembly is installed between the inner plate and the outer plate; wherein the fixing assembly includes:

[0012] The upper ring and the lower ring are both U-shaped, and the openings of the upper ring and the lower ring are opposite to each other; both sides of the upper ring and the lower ring are connected with elastic bands, and the upper ring and the lower ring are respectively connected to the inner plate and the outer plate through the elastic bands.

[0013] Preferably, the device further comprises a box-type substation, the inner plate and the outer plate are respectively located at the inner and outer sides of the box-type substation, and the mounting plate is plugged into the outer wall of the box-type substation.

[0014] Preferably, the inner plate and the outer plate are connected by bolts, and through holes are provided on the outer walls of the inner plate and the outer plate, and the elastic band is adhered to the inner walls of the through holes.

[0015] By arranging a bolt connection between the inner plate and the outer plate, the distance between the inner plate and the outer plate can be adjusted as needed, which is convenient for use with box-type substation shells of different thicknesses, thereby clamping the box-type substation shell between the inner plate and the outer plate; secondly, through holes are opened on the outer walls of the inner plate and the outer plate, and elastic bands are bonded to the inner walls of the through holes, thereby ensuring that the contact between the cable and the device is flexible, avoiding wear of the cable.

[0016] Preferably, rubber pads are bonded to the inner sides of the upper ring and the lower ring, and the interior of the rubber pads is filled with air bags.

[0017] By bonding rubber pads to the inner sides of the upper and lower rings, and filling the rubber pads with air bags, when the cable is squeezed between the upper and lower rings, the rubber pads can fully fit the cable surface, thereby improving the tightness of the connection between the upper and lower rings and the cable.

[0018] Preferably, two sets of driven screws are installed inside the mounting plate through bearings, and the two sets of driven screws are parallel to each other, wherein,

[0019] Both ends of the upper ring are installed with a first threaded plate, and both ends of the lower ring are installed with a second threaded plate, and the second threaded plate corresponds to the first threaded plate above and below, and the first threaded plate and the second threaded plate are both connected to the driven screw through threads.

[0020] Preferably, the first threaded plate is provided with an arc-shaped first thread on the outside, and the first thread is threadedly connected to the outer wall of the driven screw rod; the second threaded plate is provided with a socket on the outside for plugging with the first threaded plate, and the inner wall of one side of the socket is provided with a second thread, and the second thread is threadedly connected to the outer wall of the driven screw rod, wherein,

[0021] A driving rod is inserted into the outside of the inner plate, and a first bevel gear is provided at one end of the driving rod. The first bevel gear is meshed with a second bevel gear installed on the outside of the driven screw.

[0022] Preferably, the spiral directions of the first thread and the second thread are opposite, and both the first thread and the second thread are semi-annular and are respectively located on both sides of the driven screw.

[0023] By designing the spiral directions of the first thread and the second thread to be opposite, the upper and lower rings can be controlled to separate or close when the driven screw rotates, thereby reducing the difficulty of fixing the cable.

[0027] By designing the length of the driving rod to be greater than the width of the protective plate, when the driving rod is inserted into the inner plate, the first bevel gear installed at the end of the driving rod can mesh with the second bevel gear installed outside the driven screw.

[0028] (3) Beneficial effects

[0029] First, by setting elastic bands on both sides of the fixed component and connecting the elastic bands to the inner and outer plates, it can not only provide a certain space for the shaking of the cable, but also limit the position of the cable, thereby preventing wear and tear on the cable and the connection;

[0030] Secondly, by providing an upper ring and a lower ring that are opposite to each other, and providing a first threaded plate and a second threaded plate at the ends of the upper and lower rings, the upper and lower rings can be driven to separate and merge by controlling the rotation of the driven screw. At the same time, the distance between the upper and lower rings can be adjusted according to the size of the cable, thereby improving the applicability of the device;

[0031] Third, by setting a limit plate on the outside of the threaded plate, separation between the driven screw and the threaded plate can be prevented, thereby improving the stability of the adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In view of the problems existing in the prior art, Figure 1-8 As shown, the present invention provides an integrated device for fixing and protecting high-voltage cable incoming lines in a substation, the device comprising:

[0044] An inner plate and an outer plate are parallel to each other, and a protective plate and an extrusion plate are installed on opposite sides of the inner plate and the outer plate, respectively. A mounting plate is provided between the protective plate and the extrusion plate, and the mounting plate is connected to the protective plate and the extrusion plate respectively through slide rails; and

[0045] The fixing assembly is installed between the inner plate and the outer plate; wherein the fixing assembly includes:

[0046] The upper ring and the lower ring are both U-shaped, and the openings of the upper ring and the lower ring are opposite to each other; both sides of the upper ring and the lower ring are connected with elastic bands, and the upper ring and the lower ring are respectively connected to the inner plate and the outer plate through the elastic bands.

[0047] The inner plate and the outer plate are respectively located at the inner and outer sides of the box-type substation, and the mounting plate is plugged into the outer wall of the box-type substation.

[0048] Reference Figure 1 and Figure 2 As shown, the device also includes a box-type substation, the inner plate and the outer plate are connected by bolts, and through holes are opened on the outer walls of the inner plate and the outer plate, and the elastic band is bonded to the inner wall of the through hole.

[0049] By arranging a bolt connection between the inner plate and the outer plate, the distance between the inner plate and the outer plate can be adjusted as needed, which is convenient for use with box-type substation shells of different thicknesses, thereby clamping the box-type substation shell between the inner plate and the outer plate; secondly, through holes are opened on the outer walls of the inner plate and the outer plate, and elastic bands are bonded to the inner walls of the through holes, thereby ensuring that the contact between the cable and the device is flexible, avoiding wear of the cable.

[0050] Reference Figure 6 and Figure 7 As shown, rubber pads are bonded to the inner sides of the upper ring and the lower ring, and the interior of the rubber pads is filled with air bags.

[0051] By bonding rubber pads to the inner sides of the upper and lower rings, and filling the rubber pads with air bags, when the cable is squeezed between the upper and lower rings, the rubber pads can fully fit the cable surface, thereby improving the tightness of the connection between the upper and lower rings and the cable.

[0052] Reference Figure 2 and Figure 7 As shown, two sets of driven screws are installed inside the mounting plate through bearings, and the two sets of driven screws are parallel to each other, wherein,

[0053] A first threaded plate is installed at both ends of the upper ring, and a second threaded plate is installed at both ends of the lower ring. The second threaded plate corresponds to the first threaded plate above and below, and the first threaded plate and the second threaded plate are both connected to the driven screw through threads.

[0054] Reference Figure 6 and Figure 7 As shown, the first threaded plate is provided with an arc-shaped first thread on the outside, and the first thread is threadedly connected to the outer wall of the driven screw rod. The second threaded plate is provided with a socket on the outside for plugging with the first threaded plate, and a second thread is provided on the inner wall of one side of the socket, and the second thread is threadedly connected to the outer wall of the driven screw rod, wherein,

[0055] A driving rod is inserted into the outside of the inner plate, and a first bevel gear is provided at one end of the driving rod. The first bevel gear is meshed with a second bevel gear installed on the outside of the driven screw rod.

[0056] Reference Figure 6 and Figure 7 As shown, the spiral directions of the first thread and the second thread are opposite, and the first thread and the second thread are both semi-annular and are respectively located on both sides of the driven screw.

[0057] By designing the spiral directions of the first thread and the second thread to be opposite, the upper and lower rings can be controlled to separate or close when the driven screw rotates, thereby reducing the difficulty of fixing the cable.

[0058] Reference Figure 6 and Figure 7 As shown, the outsides of the first threaded plate and the second threaded plate are both installed with limit plates, and the surfaces of the limit plates are provided with through holes, and the driven screw rods are inserted into the through holes.

[0059] By installing limit plates on the outside of the first threaded plate and the second threaded plate, and inserting the driven screw into the inside of the through hole, separation between the driven screw and the threaded plate can be prevented, thereby improving the stability of the adjustment.

[0060] Reference Figure 2 As shown, a disc-shaped knob is installed on the outside of the driving rod, and an anti-slip layer is provided on the outside of the knob.

[0061] By arranging a knob at one end of the driving rod, when the knob is rotated, the driving rod installed at the rear end of the knob can be driven to rotate, thereby facilitating the user to manually adjust the tightness of the fit between the cable and the upper and lower rings.

[0062] Reference Figure 2 As shown, the length of the drive rod is greater than the width of the protective plate.

[0063] By designing the length of the driving rod to be greater than the width of the protective plate, when the driving rod is inserted into the inner plate, the first bevel gear installed at the end of the driving rod can mesh with the second bevel gear installed outside the driven screw.

[0064] When in use, first rotate the bolts installed between the inner plate and the outer plate to reduce the distance between the inner plate and the outer plate, thereby squeezing the shell of the box-type substation, thereby fixing the device to the shell of the box-type substation.

[0065] The cable to be fixed is passed through the through hole on the surface of the inner and outer plates, and then the driving rod is inserted into the inner plate, and the first bevel gear at the rear end of the driving rod is meshed with the second bevel gear on the outside of the driven screw rod. After completion, the knob installed on the outside of the inner plate is rotated. Since the knob is connected to the driving rod, and the driving rod is meshed with the second bevel gear installed on the outside of the driven screw rod, when the driving rod rotates, it can drive the driven screw rod to rotate. Since the driven screw rod is connected to the first threaded plate and the second threaded plate, and the spiral directions of the first thread and the second thread are opposite, when the driven screw rod rotates, the first threaded plate and the second threaded plate slide up and down along the driven screw rod under the action of the threads. Therefore, when the driven screw rod rotates, the upper and lower rings move in the direction of the cable, thereby squeezing the cable between the upper and lower rings up and down at the same time, completing the fixation of the cable. When the diameter of the cable is small, the first threaded plates at both ends of the upper ring pass through the jacks opened on the surface of the second threaded plate, thereby reducing the distance between the upper and lower rings. Figure 8 As shown, the cable between the upper and lower rings is fixed, which makes it easy to adjust the distance between the upper and lower rings according to the size of the cable, thereby improving the applicability of the device. Finally, the drive rod is removed from the inner plate to prevent non-staff from accidentally touching it.

[0066] When the cable shakes or is pulled, the cable moves outward and drives the fixed component outside it to move outward together. Since elastic bands are provided on both sides of the fixed component and the elastic bands are connected between the side plates and the fixed component, and the side plates cannot move, the elastic band on one side of the fixed component is stretched and the elastic band on the other end is squeezed and deformed during the outward movement of the fixed component. Therefore, when the fixed component moves, the elastic bands at both ends of the fixed component pull it in opposite directions, thereby preventing the cable from moving. When the fixed component contacts the side plates, it cannot move further.

[0067] To sum up, it can be seen that the cable can only shake slightly with the device. When the shaking range is large, the cable cannot move. In addition, the cable will not collide with other devices during the shaking process, thereby avoiding damage to the cable when it shakes. In addition to being suitable for box-type substations, the present invention is suitable for cable supports during cable transportation.
