Description

Technical Field

[0001] The present invention relates to the technical field of power system equipment, and in particular to an underground power cable positioning bracket and a construction method thereof. Background Art

[0002] Power underground cable positioning brackets are key devices for ensuring the safe and orderly laying of underground cables. In power transmission systems in various underground mines, such as coal and metal mines, they play a vital role in securing the cable's position, preventing entanglement, wear, and collision with the shaft wall or other equipment, providing a solid foundation for a continuous and stable power supply underground.

[0003] During the use of the cable, it will inevitably shake, which will cause friction between the cable and the positioning frame. The friction will cause the cable sheath to wear. At the same time, the cable will be affected by the temperature, and the corresponding cable will expand and contract due to heat. The thermal expansion and contraction will cause the radius of the cable to change, and also cause wear. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric power underground cable positioning bracket and a construction method thereof, so as to solve the problem that the inevitable shaking will occur during the use of the cable. The shaking will cause friction between the cable and the positioning bracket, and the friction will cause the cable sheath to be worn. At the same time, the cable will also be affected by the temperature, and the corresponding cable will expand and contract due to heat. The thermal expansion and contraction will cause the radius of the cable to change, and will also cause wear and tear problems.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a power downhole cable positioning bracket, comprising a well wall, a plurality of mounting plates fixedly mounted on the front of the well wall, a plurality of L-shaped plates fixedly mounted on the front of each of the mounting plates, a plurality of rectangular grooves respectively formed on each of the L-shaped plates, and further comprising:

[0007] Several fixing mechanisms, which include two rectangular sliders arranged in a rectangular groove, on which the two rectangular sliders are respectively fixedly mounted with mounting brackets, on which two rotating rods are respectively rotatably mounted, and several rotating rods are respectively fixedly sleeved with rubber sleeves, and adaptive blocks are respectively fixedly mounted on the tops of the two mounting brackets, and a rectangular rod is fixedly mounted in the rectangular groove, the rectangular rod passes through the two rectangular sliders and is respectively slidably connected to the two rectangular sliders, and two adaptive springs are sleeved on the rectangular rod, and the ends of the two adaptive springs close to each other are respectively fixedly connected to the two rectangular sliders.

[0008] Furthermore, moving mechanisms are respectively arranged on the mounting plate and several L-shaped plates. The moving mechanism includes T-shaped grooves respectively formed in the mounting plate and the L-shaped plates. Moving springs are respectively fixedly installed on the bottom inner walls of the two T-shaped grooves. T-shaped sliders are respectively fixedly installed at the tops of the two moving springs. The two T-shaped sliders are respectively slidably connected to the two T-shaped grooves.

[0009] Furthermore, a fixing rod is fixedly installed on the two T-shaped sliders. Two rubber clamping sleeves are rotatably sleeved on the fixing rod. A U-shaped frame is fixedly installed on the fixing rod.

[0010] Furthermore, strip plates are respectively fixedly installed on the left inner wall and the right inner wall of the U-shaped frame. A plurality of contact plates are fixedly installed on one side of the two strip plates close to each other. A plurality of movable special-shaped plates are respectively slidably sleeved on the plurality of rectangular rods. One ends of the plurality of adaptive springs away from each other are respectively fixedly connected to the plurality of movable special-shaped plates and the rectangular grooves.

[0011] Furthermore, a warning mechanism is arranged on the plurality of mounting plates. The warning mechanism includes strip-shaped chutes formed on the left sides of the plurality of mounting plates. Slide rods are respectively fixedly installed in the plurality of strip-shaped chutes. Sliding blocks are respectively slidably installed on the plurality of slide rods. Warning springs are respectively sleeved on the plurality of slide rods. The bottom ends of the plurality of warning springs are respectively fixedly connected to the plurality of sliding blocks. The top ends of the plurality of warning springs are respectively fixedly connected to the plurality of strip-shaped chutes.

[0012] Furthermore, connecting plates are respectively hingedly installed on the left sides of the plurality of sliding blocks. Rectangular connecting plates are respectively fixedly installed on the right sides of the plurality of mounting plates. Circular connecting rods are respectively fixedly installed on the fronts of the plurality of rectangular connecting plates. The plurality of circular connecting rods respectively penetrate through the plurality of connecting plates and are respectively rotatably connected to the plurality of connecting plates.

[0013] Furthermore, movable round rods are respectively fixedly installed on the tops of the plurality of sliding blocks. A plurality of warning sensors are fixedly installed on the front of the well wall.

[0014] Furthermore, for a method of a power underground cable positioning bracket, the method steps are as follows:

[0015] S1: Clamp and position the cable to reduce wear;

[0016] S2: Increase the clamping force to reduce the wear risk;

[0017] S3: Warn of faults and perform timely repairs.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention provides an electric downhole cable positioning bracket. When placing the cable, the cable is pressed down between the two adapting blocks. When the cable is pressed down, the two adapting blocks will be separated, and the adapting blocks will drive the two mounting frames away from each other. At this time, the cable is placed on the rubber clamping sleeve. Under the elastic force of the two adapting springs, a force will be generated to make the two rectangular sliders approach each other. The mounting frames will also generate a force to approach each other, thereby ensuring that the rubber sleeve will be tightly attached to the cable. When the cable shakes during use, due to the increase in friction between the rubber sleeve, the rubber clamping sleeve and the cable, the cable will drive the rubber sleeve and the rubber clamping sleeve to rotate at the same time, thereby reducing the wear of the cable sheath during shaking, improving the service life of the cable, and reducing the failure rate of the cable. When affected by the temperature, the cable will expand and contract due to heat and cold. During this process, the expansion and contraction of the cable will cause the adapting spring to undergo compression deformation and tensile deformation simultaneously, thereby ensuring that the rubber sleeve can stably clamp and position the cable and prevent wear.

[0020] (2) The present invention provides an electric downhole cable positioning bracket. After the cables are laid on the device, the cables will drive the rubber clamping sleeve to descend under the action of the cable's gravity, and the rubber clamping sleeve will drive the fixed rod to descend, and the fixed rod will drive the T-shaped frame to descend. At this time, the T-shaped slider will also descend at the same time, and the corresponding movable spring will be compressed and deformed. When the gravity of the cable is greater, the degree of compression of the movable spring will be greater, and the corresponding T-shaped frame will descend lower. The T-shaped frame drives the strip plate to descend, and the strip plate drives the contact plate to descend. During the process of the contact plate descending, it will contact the movable special-shaped plate. The movable special-shaped plate will move in the direction of the corresponding rectangular slider in the rectangular groove under the action of the contact plate. At this time, the adaptive spring between the corresponding rectangular slider and the movable special-shaped plate will produce compression deformation and push the corresponding rectangular slider to the rectangular slider away from the movable special-shaped plate. At this time, the gravity of the cable will be converted into a clamping force that brings the two rectangular sliders closer to each other. The clamping force will further firmly clamp the cable, thereby reducing cable shaking and reducing the risk of wear;

[0021] (3) The present invention provides an electric downhole cable positioning bracket. When the bolts of the mounting plate on the well wall become loose, causing the mounting plate to leave the well wall, the cable on the mounting plate that has left the well wall will cause the detached mounting plate to fall under the action of gravity, and the detached mounting plate will drive the sliding rod to fall. At this time, the circular connecting rod hinged on the mounting plate that has not fallen off will cause the connecting plate on the detached mounting plate to support the sliding block, and the corresponding sliding block will rise, causing the warning spring to be compressed and deformed, ensuring that the detached mounting plate will not fall to the bottom of the well, preventing the sewage at the bottom of the well from affecting the short circuit of the cable. The rising of the sliding block will drive the movable round rod to rise, and the movable round rod will contact the warning sensor. At this time, the staff can quickly repair the cable through the fault warning issued by the warning sensor, thereby improving the efficiency of maintenance and ensuring that the problem is minimized.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-8 As shown, the present invention is a power downhole cable positioning bracket, comprising a well wall 1, a plurality of mounting plates 2 fixedly mounted on the front of the well wall 1, a plurality of L-shaped plates 3 fixedly mounted on the front of the plurality of mounting plates 2, a plurality of rectangular grooves 4 respectively formed on the plurality of L-shaped plates 3, and further comprising:

[0036] Several fixing mechanisms 5, the fixing mechanisms 5 include two rectangular sliders 501 arranged in the rectangular groove 4, the two rectangular sliders 501 are respectively fixedly installed with mounting brackets 502, the two mounting brackets 502 are respectively rotatably installed with two rotating rods 503, several rotating rods 503 are respectively fixedly sleeved with rubber sleeves 504, and the tops of the two mounting brackets 502 are respectively fixedly installed with adaptation blocks 505, and a rectangular rod 506 is fixedly installed in the rectangular groove 4. The rectangular rod 506 passes through the two rectangular sliders 501 and is respectively slidably connected to the two rectangular sliders 501, and two adaptation springs 507 are sleeved on the rectangular rod 506, and the ends of the two adaptation springs 507 close to each other are respectively fixedly connected to the two rectangular sliders 501.

[0037] like Figure 5 As shown, a movable mechanism 6 is respectively provided on the mounting plate 2 and several L-shaped plates 3. The movable mechanism 6 includes a T-shaped slot 601 respectively opened on the mounting plate 2 and the L-shaped plate 3. A movable spring 602 is respectively fixedly installed on the bottom inner wall of the two T-shaped slots 601. A T-shaped slider 603 is respectively fixedly installed on the top of the two movable springs 602. The two T-shaped sliders 603 are respectively slidably connected to the two T-shaped slots 601.

[0038] The T-shaped slider 603 will also drop at the same time, and the corresponding movable spring 602 will be compressed and deformed. The greater the gravity of the cable, the greater the compression degree of the movable spring 602.

[0039] like Figure 2 As shown, a fixing rod 604 is fixedly installed on the two T-shaped sliders 603, two rubber clamping sleeves 605 are rotatably sleeved on the fixing rod 604, and a U-shaped frame 606 is fixedly installed on the fixing rod 604.

[0040] After the cables are all laid on the device, under the gravity of the cables, the cables will cause the rubber clamping sleeve 605 to descend, the rubber clamping sleeve 605 will cause the fixing rod 604 to descend, and the fixing rod 604 will cause the U-shaped frame 606 to descend.

[0041] As Figure 3 and Figure 6 As shown, strip plates 607 are fixedly installed on the left inner wall and the right inner wall of the U-shaped frame 606 respectively. A number of contact plates 608 are fixedly installed on one side of the two strip plates 607 close to each other. Movable special-shaped plates 609 are respectively sleeved on a number of rectangular rods 506 in a sliding manner. One end of a number of adaptation springs 507 away from each other is respectively fixedly connected to a number of movable special-shaped plates 609 and the rectangular groove 4.

[0042] The U-shaped frame 606 causes the strip plate 607 to descend, the strip plate 607 causes the contact plate 608 to descend. During the descent of the contact plate 608, it will contact the movable special-shaped plate 609. The movable special-shaped plate 609 will move in the direction close to the corresponding rectangular slider 501 in the rectangular groove 4 under the action of the contact plate 608. At this time, the adaptation spring 507 between the corresponding rectangular slider 501 and the movable special-shaped plate 609 will generate a compressive deformation, and push the corresponding rectangular slider 501 to approach the rectangular slider 501 away from the movable special-shaped plate 609. At this time, the gravity of the cable will be converted into the clamping force of the two rectangular sliders 501 approaching each other. The clamping force will further firmly clamp the cable, thereby reducing the cable shaking and reducing the risk of wear.

[0043] As Figure 7 As shown, a warning mechanism 7 is provided on a number of mounting plates 2. The warning mechanism 7 includes strip-shaped chutes 701 opened on the left side of a number of mounting plates 2. Slide rods 702 are respectively fixedly installed in a number of strip-shaped chutes 701. Slide blocks 703 are respectively slidably installed on a number of slide rods 702. Warning springs 704 are respectively sleeved on a number of slide rods 702. The bottom ends of a number of warning springs 704 are respectively fixedly connected to a number of slide blocks 703. The top ends of a number of warning springs 704 are respectively fixedly connected to a number of strip-shaped chutes 701.

[0044] When the bolts on the mounting plate 2 on the well wall 1 are loose, causing the mounting plate 2 to leave the well wall 1, the cable on the mounting plate 2 leaving the well wall 1 will cause the detached mounting plate 2 to descend under the action of gravity, and the detached mounting plate 2 will cause the slide rod 702 to descend.

[0045] As Figure 4As shown, the left sides of several sliding blocks 703 are hingedly installed with connecting plates 705, the right sides of several mounting plates 2 are fixedly installed with rectangular connecting plates 706, the front sides of several rectangular connecting plates 706 are fixedly installed with circular connecting rods 707, and several circular connecting rods 707 respectively penetrate the several connecting plates 705 and are rotatably connected to the several connecting plates 705.

[0046] At this time, the circular connecting rod 707 hinged on the non-detached mounting plate 2 will cause the connecting plate 705 on the detached mounting plate 2 to press against the sliding block 703, and the corresponding sliding block 703 will rise, causing the warning spring 704 to be compressed and deformed, ensuring that the detached mounting plate 2 will not fall to the bottom of the well, preventing the sewage at the bottom of the well from affecting the short circuit of the cable.

[0047] like Figure 7 As shown, movable round rods 708 are fixedly installed on the tops of several sliding blocks 703, and several early warning sensors 709 are fixedly installed on the front of the well wall 1.

[0048] The rise of the sliding block 703 will drive the movable round rod 708 to rise, and the movable round rod 708 will contact the early warning sensor 709. At this time, the staff can quickly repair the cable through the fault warning issued by the early warning sensor 709, thereby improving the efficiency of maintenance and minimizing the problem.

[0049] like Figures 1-8 As shown, a method for positioning a support for an underground power cable is provided, and the method steps are as follows:

[0050] S1: Cable clamping and positioning to reduce wear;

[0051] S2: Increase clamping force to reduce wear risk;

[0052] S3: Early warning faults and timely repairs.

[0053] When placing the cable, press the cable between the two adapting blocks 505. When the cable is pressed down, the two adapting blocks 505 will separate, and the adapting blocks 505 will drive the two mounting frames 502 to move away from each other. At this time, place the cable on the rubber clamping sleeve 605. Under the elastic force of the two adapting springs 507, a force will be generated to move the two rectangular sliders 501 closer to each other. The mounting frames 502 will also generate a force to move closer to each other, thereby ensuring that the rubber sleeve 504 will be tightly attached to the cable. When the cable shakes during use, due to the rubber sleeve 504 and the rubber clamping The friction between the sleeve 605 and the cable increases, and the cable will drive the rubber sleeve 504 and the rubber clamping sleeve 605 to rotate at the same time, thereby reducing the wear of the cable outer skin when shaking, improving the service life of the cable, and reducing the failure rate of the cable. When affected by the temperature, the cable will expand and contract with heat. During this process, the expansion and contraction of the cable will cause the adaptive spring 507 to undergo compression deformation and tension deformation simultaneously, ensuring that the rubber sleeve 504 can stably clamp and position the cable and prevent wear and tear. After the cables are laid on the device, the cables are pulled under the action of the gravity of the cables. The rubber clamping sleeve 605 will be driven down, and the rubber clamping sleeve 605 will drive the fixed rod 604 to be driven down, and the fixed rod 604 will drive the shaped frame 606 to be driven down. At this time, the T-shaped slider 603 will also be driven down at the same time, and the corresponding movable spring 602 will be compressed and deformed. When the gravity of the cable is greater, the degree of compression of the movable spring 602 will be greater, and the corresponding shaped frame 606 will be driven down. The shaped frame 606 drives the strip plate 607 to be driven down, and the strip plate 607 drives the contact plate 608 to be driven down. When the contact plate 608 is driven down, it will contact the movable special-shaped plate 606. 09, the movable special-shaped plate 609 will move towards the direction of the corresponding rectangular slider 501 in the rectangular slot 4 under the action of the contact plate 608. At this time, the adaptive spring 507 between the corresponding rectangular slider 501 and the movable special-shaped plate 609 will produce compression deformation and push the corresponding rectangular slider 501 towards the rectangular slider 501 away from the movable special-shaped plate 609. At this time, the gravity of the cable will be converted into a clamping force that brings the two rectangular sliders 501 closer to each other. The clamping force will further firmly clamp the cable, thereby reducing cable shaking and reducing the risk of wear;

[0054] When the bolts of the mounting plate 2 on the well wall 1 become loose, causing the mounting plate 2 to leave the well wall 1, the cable on the mounting plate 2 that has left the well wall 1 will cause the detached mounting plate 2 to drop under the action of gravity, and the detached mounting plate 2 will drive the sliding rod 702 to drop. At this time, the circular connecting rod 707 hinged on the mounting plate 2 that has not fallen off will cause the connecting plate 705 on the detached mounting plate 2 to support the sliding block 703, and the corresponding sliding block 703 will rise, causing the warning spring 704 to be compressed and deformed, ensuring that the detached mounting plate 2 will not fall to the bottom of the well, preventing the sewage at the bottom of the well from affecting the short circuit of the cable. The rising of the sliding block 703 will drive the movable round rod 708 to rise, and the movable round rod 708 will contact the warning sensor 709. At this time, the staff can quickly repair the cable through the fault warning issued by the warning sensor 709, thereby improving the efficiency of maintenance and minimizing the problem.

Obviously, many modifications and variations are possible based on the content of this specification.
