Description

Technical Field

[0001] The present invention relates to the technical field of drainage line installation, and in particular to a drainage line fixer and a fixing method for distribution network operations. Background Art

[0002] The distribution network, also known as the power grid, refers to a power network that receives electric energy from the transmission network or regional power plant, distributes it locally or distributes it step by step according to voltage to various users through distribution facilities. It is composed of overhead lines, cables, poles, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities, and plays an important role in distributing electric energy in the power grid. The distribution network drainage line is an important component of the distribution network system. The drainage line is used to guide or connect the current in the distribution network to transfer electric energy from one device or system to another. The design and installation of drainage lines are crucial to the safe operation of the distribution network because they need to withstand the transmission of current and ensure that the current can flow to the target location stably and efficiently. In the non-stop operation of the 10kV distribution network, the two broken ends of the unconnected or disconnected wires are prone to shaking due to the softness of the wires, wind swing and other reasons. In order to ensure the stability of the line, the staff will use a special fixture to fix the drainage line.

[0003] The Chinese patent with application number CN202020698913.6 discloses a drainage wire fixing device, including a clamp and a supporting crossarm fixed to one side of the clamp, and a plurality of wiring holes are provided on the supporting crossarm. The fixing device can fix the drainage wire well by installing a temporary fixing device on the pole, thereby solving the problem of wire shaking, allowing operators to work safely and avoiding personal or equipment accidents. Since the drainage wire is fixed by two mutually engaged clamps, the supporting crossarm is fixed to one side of the clamp, and the structural strength of the connection between the clamp and the supporting crossarm is relatively weak, when the clamp is assembled, if it collides with an external object, it is easy to cause the clamp to deform and deflect, which in turn affects the erection of the drainage wire.

DETAILED DESCRIPTION

[0037] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0038] Embodiment 1:

[0039] according to Figure 1 , 2 , 3, 4, and 5, in the first embodiment, a distribution network operation drainage line fixture is proposed, including a plurality of frame plates 1, a spacing expansion 2 is provided between two adjacent frame plates 1, a V-shaped bracket 3 is provided outside the spacing expansion 2, and the two ends of the V-shaped bracket 3 are respectively fixedly connected to the two frame plates 1; the two ends of the V-shaped bracket 3 are fixed to the frame plates 1 by welding, as shown in the attached Figure 1 As shown, the V-shaped bracket 3 faces the direction of the spacing expansion 2, which can be upward or downward, and is not limited to one direction.

[0040] A first cross pressure plate and a second cross pressure plate are provided in the V-shaped bracket 3. The first cross pressure plate is placed above the second cross pressure plate and cross-matched with the second cross pressure plate. The drainage line that needs to be laid enters the V-shaped bracket 3 from the interval expansion 2, and then passes through the first cross pressure plate and the second cross pressure plate. The interval between the first cross pressure plate and the second cross pressure plate allows the wire harness to enter directly.

[0041] The end of the V-shaped bracket 3 away from the interval expansion 2 is provided with a height adjustment mechanism for controlling the opening and closing of the first cross pressure plate and the second cross pressure plate, and the end of the V-shaped bracket 3 close to the interval expansion 2 is provided with a frame structure for supporting the second cross pressure plate. The frame structure is arranged at the bottom of the second cross pressure plate, and is used to support the second cross pressure plate and fix the second cross pressure plate and the V-shaped bracket 3 together. The first cross pressure plate is arranged above the C-shaped pressure plate 4. When the wiring harness enters between the first cross pressure plate and the second cross pressure plate, the height adjustment mechanism will push the first cross pressure plate to fall, and the first cross pressure plate and the second cross pressure plate will cross-coordinate to fix the wiring harness. The V-shaped bracket 3 can cooperate with the two cross pressure plates to protect the wiring harness at the same time, and has high reliability.

[0042] Regarding the first cross-type pressing plate: the first cross-type pressing plate includes a C-type pressing plate 4, which is placed in a V-shaped bracket 3. A plurality of pressing plate pins 41 are provided on both sides of the C-type pressing plate 4. The pressing plate pins 41 extend away from one end of the C-type pressing plate 4 to both sides of the second cross-type pressing plate, and a gap is left between two adjacent pressing plate pins 41. It should be noted that the spacing between each pressing plate pin 41 is equal. The C-type pressing plate 4 and the pressing plate pins 41 are integrally formed.

[0043] Regarding the second cross-type pressing plate: the second cross-type pressing plate includes a C-type pallet 5, which is placed below the C-type pressing plate 4. A plurality of pallet pins 51 are provided on both sides of the C-type pallet 5. The pallet pins 51 extend away from one end of the C-type pallet 5 to both sides of the C-type pressing plate 4. The pallet pins 51 are staggered from the pressing plate pins 41, and the width of the pallet pins 51 is less than the spacing width. It should also be noted that the spacing between the pallet pins 51 of the C-type pallet 5 is equal. The C-type pallet 5 and the pallet pins 51 are integrally formed.

[0044] When fixing the drainage line, the C-shaped pressure plate 4 is pushed down through the height adjustment mechanism. After the C-shaped pressure plate 4 falls, the pressure plate pins 41 on both sides of the C-shaped pressure plate 4 will be inserted into the gap formed between the respective support plate pins 51 on both sides of the C-shaped support plate 5. The pressure plate pins 41 and the support plate pins 51 cross each other. Under the limitation of the pressure plate pins 41 and the support plate pins 51, the C-shaped pressure plate 4 and the C-shaped support plate 5 can stably clamp the drainage line.

[0045] The height of the C-type pressing plate 4 is controlled by a height adjustment mechanism, which includes an adjustment screw 7 and a positioning plate 42. The positioning plate 42 is fixedly connected to the upper end of the C-type pressing plate 4, and the adjustment screw 7 is installed on the upper end of the V-shaped bracket 3. The lower end of the adjustment screw 7 passes through the V-shaped bracket 3 and is rotatably connected to the positioning plate 42. The adjustment screw 7 is threadedly connected to the V-shaped bracket 3, and a screw head 71 is provided on the upper end of the adjustment screw 7. The height adjustment mechanism is a common screw lifting structure. When adjusting the height of the C-type pressing plate 4, the screw head 71 can be rotated. The adjusting screw 7 is rotated by the screw head 71. When the adjusting screw 7 is rotated, it will be screwed into the V-shaped bracket 3. The C-type pressing plate 4 moves closer to the C-shaped support plate 5 under the push of the adjustment screw 7, and then the drainage line is fixed.

[0046] The support structure is arranged at the lower end of the C-shaped support plate 5, and is used to support the C-shaped support plate 5. Specifically, the support structure includes a support plate 6, one end of which is fixedly connected to the lower end of the C-shaped support plate 5, and the other end of the support plate 6 is fixedly connected to one end of the V-shaped bracket 3. A plurality of first diagonal support ribs 61 and a plurality of second diagonal support ribs 62 are arranged between the support plate 6 and the C-shaped support plate 5. The two ends of the first diagonal support rib 61 are respectively fixedly connected to the support plate pin 51 and the support plate 6, and the two ends of the second diagonal support rib 62 are respectively fixedly connected to the V-shaped bracket 3 and the first diagonal support rib 61. The C-shaped support plate 5 is fixed to the V-shaped bracket 3 through the support plate 6. The first diagonal support rib 61 is arranged between the C-shaped support plate 5 and the support plate 6, and plays the role of a reinforcing rib, which is used to improve the structural strength of the connection between the C-shaped support plate 5 and the support plate 6. The second diagonal support rib 62 is arranged between the first diagonal support rib 61 and the V-shaped bracket 3, and also plays the role of a reinforcing rib, which is used to improve the structural strength of the connection between the support plate 6 and the V-shaped bracket 3.

[0047] It should be noted that the support plate 6 is provided with a plurality of second slots 63 for allowing the pressing plate pins 41 to be inserted. After the C-shaped pressing plate 4 falls, the pressing plate pins 41 on both sides of the C-shaped pressing plate 4 will not conflict with the support plate 6.

[0048] Embodiment 2:

[0049] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, in order to prevent the C-type pressing plate 4 from rotating when it is rising and falling, so that the pressing plate pins 41 on both sides of the C-type pressing plate 4 cannot accurately cross with the supporting plate pins 51 on both sides of the C-type supporting plate 5, the end of the positioning plate 42 away from the C-type pressing plate 4 is inserted into the limiting groove 31 provided on the side of the V-shaped bracket 3, and the C-type pressing plate 4 is slidably connected with the limiting groove 31. When the height adjustment mechanism pushes the C-type pressing plate 4 to fall, the positioning plate 42 fixed to the C-type pressing plate 4 will also fall together, and the limiting groove 31 cooperates with the positioning plate 42 to guide the positioning plate 42, so that the C-type pressing plate 4 will not deflect when falling.

[0050] It should be noted that the positioning plate 42 is provided with a plurality of first slots 43 for inserting the pallet pins 51. Similarly, after the C-shaped pressing plate 4 falls, due to the presence of the first slots 43, the positioning plate 42 will not conflict with the pallet pins 51 on both sides of the C-shaped pallet 5.

[0051] Embodiment three:

[0052] according to Figure 1 , 2 As shown in , 3, 4, and 5, in order to avoid excessive squeezing of the wire harness when the C-type pressing plate 4 and the C-type supporting plate 5 are close to each other, resulting in aggravated wear of the surface of the wire harness and affecting the service life of the drainage line, the inner wall of the C-type pressing plate 4 is provided with a first rubber pad 44, and the first rubber pad 44 is fixedly connected to the C-type pressing plate 4, and the inner wall of the C-type supporting plate 5 is provided with a second rubber pad 52, and the second rubber pad 52 is fixedly connected to the C-type supporting plate 5, and the second rubber pad 52 is placed below the first rubber pad 44. When the C-type pressing plate 4 and the C-type supporting plate 5 are aligned, the surface of the wire harness will contact the first rubber pad 44 and the second rubber pad 52, and the first rubber pad 44 and the second rubber pad 52 can protect the wire harness and improve the service life of the drainage line.

[0053] Working principle: The drainage line to be laid enters the V-shaped bracket 3 from the interval expansion 2, and then passes between the first cross pressure plate and the second cross pressure plate. The interval between the first cross pressure plate and the second cross pressure plate allows the wire harness to enter directly.

[0054] The first cross-type pressure plate is arranged above the C-type pressure plate 4. When the wire harness enters between the first cross-type pressure plate and the second cross-type pressure plate, the height adjustment mechanism pushes the C-type pressure plate 4 to fall. After the C-type pressure plate 4 falls, the pressure plate pins 41 on both sides of the C-type pressure plate 4 will be inserted into the gap formed between the respective support plate pins 51 on both sides of the C-type support plate 5. The pressure plate pins 41 and the support plate pins 51 cross each other. Under the limit of the pressure plate pins 41 and the support plate pins 51, the C-type pressure plate 4 and the C-type support plate 5 can stably clamp the drainage line. The V-shaped bracket 3 can cooperate with two cross-type pressure plates to protect the wire harness at the same time, and has strong reliability.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments are only for explaining the principles of the present invention.
