[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 4 The present invention provides the following technical solutions: an installation structure of a hydropower plant lightning arrester, comprising a valve-type lightning arrester body 1 and a mounting bracket 2 fixed to the bottom end of the valve-type lightning arrester body 1, a mounting hole 21 being processed on the mounting bracket 2, and also comprising: a fixed beam 3, a flip beam 4, a mounting shaft 5 and an adjustment component 6.

[0041] Further, by Figure 1 and Figure 2 As shown, in the present embodiment, a fixing hole 31 is processed on the fixed beam 3, which is used to fix the fixed beam 3 to the top of the fixed object, and two symmetrically distributed No. 1 mounting ears 32 with holes are fixed at one end of the fixed beam 3, the valve type lightning arrester body 1 is fixed on the flipping beam 4, and a connecting block 41 is fixed on the bottom surface of the flipping beam 4, the mounting shaft 5 is fixed on the connecting block 41, and the mounting shaft 5 passes through the No. 1 mounting ear 32 with holes to form a rotating structure, and the adjustment component 6 is used to drive the flipping beam 4 to flip. After adopting the above scheme, when in use, first use bolts to fix the fixed beam 3 to the top of the fixed object, and then fix the valve type lightning arrester body 1 on the flipping beam 4, and then observe the state of the valve type lightning arrester body 1. If the valve type lightning arrester body 1 is in a tilted state, use the adjustment component 6 in time to adjust the tilt angle of the flipping beam 4 to ensure that the valve type lightning arrester body 1 is in a vertical state, thereby ensuring a better lightning protection effect and being suitable for most different installation scenarios.

[0042] It should be noted that, in actual use, the fixed crossbeam 3 needs to be installed along the inclination direction of the top surface of the fixed object to ensure that the adjustment direction of the flip crossbeam 4 is consistent with the inclination direction of the top surface of the fixed object.

[0043] It should be further pointed out that the fixed beam 3 of the present invention is a long straight structure and has a fixed hole 31 reserved therein. When it is fixed and installed with bolts during use, it is necessary to machine a connecting hole on the fixed object. In the case where it is inconvenient to machine the hole, other conventional means can also be used to fix the fixed beam 3, such as welding.

[0044] The fixed crossbeam 3 and the flip crossbeam 4 of the present invention are both common profiles. The present invention adopts square tubes, and square tubes made of materials such as aluminum alloy and stainless steel can be selected for processing.

[0045] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the adjustment component 6 includes: a worm wheel 61, a No. 2 mounting ear with a hole 62 and a worm 63. The worm wheel 61 is fixed on the mounting shaft 5. The two No. 2 mounting ears with a hole 62 are symmetrically fixed to the outer wall of the No. 1 mounting ear with a hole 32. The worm 63 is rotatably installed between the two No. 2 mounting ears with a hole 62, and the worm 63 is meshed with the worm wheel 61. After adopting the above scheme, when in use, the worm 63 is rotated, and the worm 63 drives the worm wheel 61 to rotate through the meshing action. The worm wheel 61 drives the flip beam 4 to flip using the mounting shaft 5 to adjust the inclination angle of the flip beam 4.

[0046] It should be noted that the above scheme is only a preferred embodiment of the present invention and is not used to limit the present invention. In actual use, a motor can also be used to drive the flip beam 4 to flip. It is worth mentioning that the meshing cooperation between the worm 63 and the worm wheel 61 has a reverse self-locking feature and has high stability.

[0047] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: a regular hexagonal knob 64, one end of the worm 63 extends out of the second mounting ear 62 with a hole, and the regular hexagonal knob 64 is fixed on the protruding end of the worm 63. After adopting the above scheme, when in use, the regular hexagonal knob 64 can be clamped with the help of a wrench to rotate so as to rotate the worm 63. In other available embodiments, if adjustment allows, a motor can also be used to drive the worm 63 to rotate, but the motor needs to be connected to an electrical power source, and a position that is easy to operate needs to be selected to install a power switch that controls the operation of the motor.

[0048] It should be noted that the above solution is only an exemplary solution of the present invention and is not intended to limit the present invention. If conditions permit, a motor can also be used to drive the worm 63 to rotate.

[0049] Optionally, by Figure 1-Figure 3As shown, in this embodiment, a fixing component 7 is also included. The mounting bracket 2 is fixed to the flip beam 4 by the fixing component 7, and the fixing component 7 includes: a clamping plate 71, a positioning rod 72, a fixing block 73 and a long bolt 74. A No. 2 through hole 711 is processed on the clamping plate 71, the positioning rod 72 is fixed to the bottom surface of the clamping plate 71 and passes through the mounting hole 21, the fixing block 73 is fixed to the outer wall of the flip beam 4, and a threaded hole 731 is processed on the fixing block 73. The long bolt 74 passes through the No. 2 through hole 711 and is screwed into the threaded hole 731 by threaded engagement. After adopting the above scheme, when installing the valve-type lightning arrester body 1, the bottom surface of the mounting bracket 2 is made to fit the top surface of the flip beam 4, and the mounting hole 21 is made to face the positioning rod 72, and then the long bolt 74 is tightened until the positioning rod 72 passes through the mounting hole 21, and the clamping plate 71 clamps the mounting bracket 2, so that the stable installation of the valve-type lightning arrester body 1 can be completed.

[0050] It should be noted that the above scheme is only a preferred implementation scheme of the present invention and is not used to limit the present invention. In actual use, the mounting bracket 2 can also be directly fixed with bolts. As a preferred scheme, the mounting bracket 2 is fixed by the fixing assembly 7. When the valve type lightning arrester body 1 needs to be disassembled, there is no need to completely unscrew the long bolt 74. It is only necessary to loosen the long bolt 74. After pulling out the positioning rod 72, the valve type lightning arrester body 1 can be removed. It is more convenient and will not cause the long bolt 74 and the clamping plate 71 to be accidentally lost.

[0051] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a stop block 712, which is fixed to the bottom surface of the clamping plate 71, and the end surface of the mounting bracket 2 abuts against the outer wall of the stop block 712. After adopting the above scheme, after the valve type lightning arrester body 1 is installed, the end surface of the mounting bracket 2 abuts against the outer wall of the stop block 712, which can further improve the stability of the valve type lightning arrester body 1 after installation and avoid accidental slippage of the valve type lightning arrester body 1.

[0052] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, a through hole No. 42 for the positioning rod 72 to pass through is processed on the flip beam 4. After adopting the above scheme, after the valve-type lightning arrester body 1 is installed, the positioning rod 72 passes through the through hole No. 42, so that the locking of the clamping plate 71 is more stable, and the lower end of the positioning rod 72 is limited by the flip beam 4 to prevent the positioning rod 72 from bending and deformation.

[0053] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, the inner diameter of the No. 1 through hole 42 is equal to the inner diameter of the mounting hole 21 and is equal to the diameter of the positioning rod 72, and has high stability to prevent the valve type arrester body 1 from accidentally slipping.

[0054] Preferably, by Figure 1As shown, the present embodiment also includes: a spirit level 8, which is fixed to the outer wall of the flip beam 4. After adopting the above scheme, when in use, the spirit level 8 can be used to observe the state of the flip beam 4, so as to facilitate the adjustment of the flip beam 4 to a horizontal state. At the same time, by observing the spirit level 8, it is also helpful to grasp the state of the fixed beam 3, facilitate the adjustment of the installation direction of the fixed beam 3, and ensure that the fixed beam 3 is installed along the inclination direction of the top surface of the fixed object.

[0055] It should be noted that the vial 8 can be fixed to any side wall of the flip beam 4 when in use, but it is necessary to ensure that the length direction of the vial 8 is consistent with the length direction of the flip beam 4.

[0056] Components not described in detail herein are prior art.

[0057] Working principle and use process of the present invention: When the valve type arrester body 1 of the present invention is used, firstly, the fixed beam 3 is fixed to the top of the fixed object with bolts, and then the valve type arrester body 1 is fixed to the flip beam 4, so that the bottom surface of the mounting bracket 2 fits the top surface of the flip beam 4, and the mounting hole 21 faces the positioning rod 72, and then the long bolt 74 is tightened until the positioning rod 72 passes through the mounting hole 21, and the pressing plate 71 presses the mounting bracket 2, so that the valve type arrester body 1 can be stably installed;

[0058] Thereafter, the state of the valve type lightning arrester body 1 is determined by observing the spirit bubble 8. If the valve type lightning arrester body 1 is in a tilted state, the worm 63 is promptly rotated so that the worm 63 drives the worm wheel 61 to rotate through meshing. The worm wheel 61 drives the flip beam 4 to flip using the installation shaft 5. The tilt angle of the flip beam 4 is adjusted to ensure that the valve type lightning arrester body 1 is in a vertical state, thereby ensuring a better lightning protection effect and being suitable for most different installation scenarios.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
