DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1: Figures 1 to 5 As shown, a safety protection fence for a box transformer in a wind farm described in an embodiment of the present invention comprises a pair of vertical poles 1; a pair of cross bars 2 are fixedly connected to the sides of the vertical poles 1 close to each other, and a group of baffles 3 are fixedly connected to the cross bars 2, and the top of the baffles 3 is conical; a first slide groove 9 is provided on the bottom surface of the vertical pole 1, and a plug rod 5 is arranged in the first slide groove 9, and the bottom surface of the plug rod 5 is conical, and a first spring is fixedly connected between the top surface of the plug rod 5 and the inner wall of the first slide groove 9; a group of card grooves 6 are provided on the side wall of the plug rod 5, and a card plate 7 extending into the first slide groove 9 is slidably connected to the side wall of the vertical pole 1, and the card plate 7 can be carded with the card groove 6; a fixing plate 8 is fixedly connected to the top surface of the card plate 7, and a second spring is fixedly connected between the fixing plate 8 and the side wall of the vertical pole 1;

[0032] When the protective fence in the present application needs to be used on a cement concrete floor, first assemble the vertical pole 1 and the horizontal pole 2 into a protective fence, and then pull the card plate 7 to make the card plate 7 slide out of the card slot 6. At this time, the first spring will pull the insertion rod 5, so that the insertion rod 5 is retracted into the first sliding groove 9. At this time, the vertical pole 1 can be placed normally on the cement concrete floor, allowing the protective fence to surround the wind farm box for protection. When the card plate 7 is engaged with the card slot 6, the thrust of the second spring is not enough to disengage the card plate 7 from the card slot 6. The second spring can prevent the card plate 7 from falling off from the vertical pole 1. When the protective fence is used on a muddy ground, it can be pulled by pulling the insertion rod 5. The insertion rod 5 moves downward, and when the vertical pole 1 slides to the appropriate position, the clamping plate 7 can be pushed to engage with the clamping slot 6. The insertion depth of the insertion rod 5 is different in different geological conditions. For softer soil, the insertion rod 5 needs to be inserted deeper. The present application can adaptively adjust the position of the vertical pole 1 and can also be adapted to use in soils of different geology. The insertion rod 5 can then be inserted into the ground, and then the top of the vertical pole 1 can be hammered to allow the insertion rod 5 to be fully inserted into the ground, thereby completing the fixation of the protective fence. Through the above-mentioned mechanism, the protective fence in the present application can be adapted to a variety of environments for use, so as to improve the flexibility and extensiveness of the use of the protective fence.

[0033] The side wall of the plug rod 5 is provided with a second sliding groove 10 penetrating therethrough, a pair of fixed cones 11 are sealed and slidably connected in the second sliding groove 10, a third spring is fixedly connected to the side of the fixed cones 11 close to each other, a first cavity 12 connected to the second sliding groove 10 is provided in the plug rod 5, an air inlet 14 connected to the first cavity 12 is provided on the top surface of the plug rod 5, the plug rod 5 is sealed and slidably connected to the inner wall of the first sliding groove 9, a first through hole 16 connected to the first sliding groove 9 is provided on the side wall of the vertical rod 1, and a sealing mechanism for sealing the first through hole 16 and the air inlet 14 is provided in the vertical rod 1;

[0034] When the rod 5 is inserted into the first slide groove 9, the first through hole 16 is in an open state, so that the rod 5 can slide upward. In the process of inserting the rod 5 into the ground, the first through hole 16 and the air inlet 14 are both in a sealed state. When the rod 5 is about to be completely inserted into the ground, the sealing mechanism can no longer seal the air inlet 14, and at the same time, the clamping plate 7 is pulled out of the clamping groove 6, and then the vertical pole 1 is hammered downward. At this time, the vertical pole 1 will slide downward and contact the ground. At this time, the rod 5 will push the gas in the first slide groove 9 into the first cavity 12 from the air inlet 14, and then push the fixing cone 11 to be inserted horizontally into the soil, thereby improving the fixing effect of the vertical pole 1. When the fixing cone 11 needs to be pulled out of the ground, it is only necessary to open the first through hole 16 to allow gas to flow in the first slide groove 9. At this time, the third spring will pull the fixing cone 11 into the second slide groove 10, and then the vertical pole 1 can be pulled out of the ground.

[0035] The sealing mechanism includes a sealing block 13 sliding on the top surface of the first cavity 12, the sealing block 13 is made of a magnetic material, and the top surface of the sealing block 13 can seal the air inlet 14, and the card plate 7 is made of a magnetic material that is magnetically attracted to the sealing block 13; in the present application, when the air inlet 14 needs to be opened, it is after the insertion rod 5 is about to be fully inserted into the ground. At this time, the card plate 7 can be pulled to disengage the card plate 7 from the card slot 6, and at the same time, the card plate 7 will drive the sealing block 13 to move, so that the sealing block 13 no longer seals the first through hole 16, and at this time, the vertical rod 1 can be hammered to allow the insertion rod 5 to push the gas in the first slide groove 9 from the air inlet 14 into the first cavity 12, and then push the fixed cone 11 to be inserted into the ground. When the air inlet 14 needs to be sealed, the card plate 7 is in a state of being connected to the card slot 6. At this time, the card plate 7 will limit the position of the sealing block 13 at the air inlet 14 to seal the air inlet 14.

[0036] The sealing mechanism also includes an elastic block 15 fixedly connected to the inner wall of the first cavity 12, the elastic block 15 is hollow inside, a rectangular groove connected to the first through hole 16 is provided in the vertical rod 1, a first sealing plate 17 sealing the first through hole 16 is sealingly slidably connected to the inner wall of the rectangular groove, a fourth spring is fixedly connected between the bottom surface of the first sealing plate 17 and the inner wall of the rectangular groove, and a connecting pipe 18 is connected between the elastic block 15 and the rectangular groove;

[0037] When the sealing block 13 in the present application is driven by the clamping plate 7 to move to a position away from the air inlet 14, it will squeeze the elastic block 15. At this time, the gas in the elastic block 15 will enter the rectangular groove from the connecting pipe 18, thereby pushing the first sealing plate 17 to seal the first through hole 16. At this time, when the vertical rod 1 is hammered, the gas in the first slide groove 9 will only enter the first cavity 12. Then, when the first through hole 16 and the air inlet 14 need to be opened at the same time, it is only necessary to control the clamping plate 7 to push the sealing block 13 to move so that the sealing block 13 no longer squeezes the elastic block 15. At this time, the first sealing plate 17 will be reset under the pull of the fourth spring, and will no longer seal the first through hole 16. At the same time, the position of the sealing block 13 and the air inlet 14 is staggered. Through the above-mentioned mechanism, the first sealing plate 17 can be driven to seal the first through hole 16 when the sealing block 13 does not seal the air inlet 14.

[0038] The top surface of the vertical pole 1 is provided with an alarm 4, the top surface of the insertion rod 5 is fixedly connected with a first contact 19, the inner wall of the first slide groove 9 is fixedly connected with a second contact 20, and the alarm 4 can be activated when the first contact 19 contacts the second contact 20, the side wall of the vertical pole 1 is provided with a second through hole 24 connected with the first slide groove 9, and a sealing component is arranged in the second through hole 24, and the side wall of the vertical pole 1 is sealed and slidably connected with a round rod 21 extending into the first slide groove 9, and both ends of the round rod 21 are fixedly connected with The first slide groove 9 is provided with a positioning groove 22 on the inner wall of the round rod 21, and the positioning groove 22 is engaged with the round disc 23; when the upright pole 1 is used on a cement floor, the round rod 21 can be pushed to block the insertion rod 5 to prevent the first contact 19 from accidentally contacting the second contact 20 when the insertion rod 5 is received into the first slide groove 9, thereby activating the alarm 4. When the safety protection fence is used on a cement floor, the location where it is generally located is not remote. When it is used on a mud floor, if it is in a remote place, there will be wild animals. In order to prevent wild animals from destroying the protective fence, causing the protective fence to fall down, and then destroying the wind farm box, when the safety protective fence in the present application is used in a remote field, it is necessary to first insert the insertion rod 5 and the fixing cone 11 into the ground. At the end of this work, the first through hole 16 and the second through hole 24 need to be in a sealed state, otherwise there will be gas circulation in the first chute 9, allowing the fixing cone 11 to be collected into the second chute 10, and then the round rod 21 is pulled to allow the disc 23 to engage with the positioning groove 22. At this time, the round rod 21 no longer blocks the top of the insertion rod 5, and the wind farm box is prevented from being damaged. When the guardrail is destroyed and collapsed by wild animals, the vertical pole 1 will tilt from the soil or be pulled out. When the vertical pole 1 tilts in the soil, the resistance of the vertical pole 1 sliding in the soil will be greatly reduced. At this time, the sealing assembly will no longer seal the second through hole 24. At this time, the first spring will pull the plug rod 5, so that the plug rod 5 slides under the pull of the first spring, so that the first contact 19 contacts the second contact 20 to activate the alarm 4. At this time, the alarm 4 will sound and light alarm to scare away the wild animals to prevent the wild animals from continuing to damage the wind farm box.

[0039] The sealing assembly includes a third slide groove 28 provided in the vertical pole 1 and connected with the second through hole 24, a second slide plate sealing the second through hole 24 is slidably connected in the third slide groove 28, a movable groove 26 connected with the third slide groove 28 is provided in the vertical pole 1, a ball 27 is provided in the movable groove 26, the ball 27 is rotatably connected with the second sealing plate 25, and a group of circular holes misaligned with the second through hole 24 are provided on the second sealing plate 25; if the vertical pole 1 is damaged and tilted in the present application, the ball 27 will drive the second sealing plate 25 to move, as long as the second sealing plate 25 moves, the circular holes on the second sealing plate 25 can move to the second through hole 24, and the gas in the second slide groove 10 can flow normally, so that the first spring pulls the plug 5 to make the first contact 19 contact with the second contact 20 to start the alarm 4.

[0040] Embodiment 2: Figure 6 As shown, compared with Example 1, another implementation of the present invention is: a second cavity 29 is opened in the vertical pole 1, and an elastic hollow ball 30 is arranged in the second cavity 29, and red gas is stored in the hollow ball 30, and a group of air outlet holes connected with the second cavity 29 are opened on the side wall of the vertical pole 1, and a puncture component for puncturing the hollow ball 30 is arranged on the vertical pole 1; when the vertical pole 1 falls over, the hollow ball 30 can be punctured with the help of the puncture mechanism, and the gas in the hollow ball 30 will be discharged from the air outlet, and people around can observe the red gas to timely repair the protective fence.

[0041] The puncture assembly includes a push rod 33 fixedly connected to the top surface of the insertion rod 5, and the inner wall of the second cavity 29 is provided with a connecting hole 31 connected to the first slide groove 9, and a puncture cone 32 is sealed and slidably connected in the connecting hole 31, and the connecting hole 31 corresponds to the push rod 33, and the outer diameter of the push rod 33 is smaller than the inner diameter of the connecting hole 31; when the vertical pole 1 in the present application is tilted, the first spring will pull the insertion rod 5 to move upward, and at this time the insertion rod 5 will drive the push rod 33 to enter the connecting hole 31, and at this time the push rod 33 will push the puncture cone 32 to puncture the hollow ball 30 to discharge the red gas.

[0042] like Figure 7 As shown, a method for using a wind farm box transformer safety protection fence, the method adopts the above-mentioned wind farm box transformer safety protection fence, the method comprises the following steps:

[0043] S1: When the protective fence needs to be used on a cement concrete floor, first assemble the vertical pole 1 and the horizontal pole 2 into the protective fence, then pull the clamping plate 7 out of the clamping slot 6, and then the first spring will pull the insertion rod 5 so that the insertion rod 5 is retracted into the first sliding slot 9;

[0044] S2: Place the pole 1 normally on the cement concrete ground, and let the protective fence surround the wind farm box for protection;

[0045] S3: When the protective fence is used on muddy ground, the insertion rod 5 can be pulled to move the insertion rod 5 downward. When the vertical rod 1 slides to a suitable position, the clamping plate 7 can be pushed to engage with the clamping slot 6;

[0046] S4: Then the insertion rod 5 can be inserted into the ground, and then the top of the vertical pole 1 is hammered to allow the insertion rod 5 to be completely inserted into the ground, thereby completing the fixing of the protective fence.

[0047] Working principle: When the protective fence in this application needs to be used on a cement concrete floor, first assemble the vertical pole 1 and the horizontal pole 2 into a protective fence, and then pull the card plate 7 to make the card plate 7 slide out of the card slot 6. At this time, the first spring will pull the plug rod 5 to retract the plug rod 5 into the first slide slot 9. At this time, the vertical pole 1 can be placed normally on the cement concrete floor, allowing the protective fence to surround the wind farm box for protection. When the card plate 7 is engaged with the card slot 6, the thrust of the second spring is not enough to disengage the card plate 7 from the card slot 6. The second spring can prevent the card plate 7 from falling off from the vertical pole 1. When the protective fence is used on muddy ground, it can be pulled by pulling the plug rod 5 , so that the insertion rod 5 moves downward. When the vertical pole 1 slides to the appropriate position, the card plate 7 can be pushed to engage with the card slot 6. The insertion depth of the insertion rod 5 required for different geological conditions is also different. For softer soil, the insertion rod 5 needs to be inserted deeper. The present application can adaptively adjust the position of the vertical pole 1 and can also be used for soil with different geology. Then, the insertion rod 5 can be inserted into the ground, and then the top of the vertical pole 1 can be hammered to allow the insertion rod 5 to be completely inserted into the ground, thereby completing the fixation of the protective fence. Through the above mechanism, the protective fence in the present application can be adapted to a variety of environments for use, so as to improve the flexibility and extensiveness of the use of the protective fence.

[0048] When the rod 5 is received into the first slide groove 9, the first through hole 16 is in an open state, so that the rod 5 can slide upward. In the process of inserting the rod 5 into the ground, the first through hole 16 and the air inlet 14 are both in a sealed state. When the rod 5 is about to be completely inserted into the ground, the sealing mechanism can no longer seal the air inlet 14, and at the same time, the clamping plate 7 is pulled out of the clamping groove 6, and then the vertical pole 1 is hammered downward. At this time, the vertical pole 1 will slide downward and contact the ground. At this time, the rod 5 will push the gas in the first slide groove 9 into the first cavity 12 from the air inlet 14, and then push the fixing cone 11 to be inserted horizontally into the soil, thereby improving the fixing effect of the vertical pole 1. When the fixing cone 11 needs to be pulled out of the ground, it is only necessary to open the first through hole 16 to allow gas to flow in the first slide groove 9. At this time, the third spring will pull the fixing cone 11 into the second slide groove 10, and then the vertical pole 1 can be pulled out of the ground.

[0049] When the air inlet 14 needs to be opened in the present application, it is after the insertion rod 5 is about to be completely inserted into the ground. At this time, the card plate 7 can be pulled to disengage the card plate 7 from the card slot 6. At the same time, the card plate 7 will drive the sealing block 13 to move, so that the sealing block 13 no longer seals the first through hole 16. At this time, the vertical rod 1 can be hammered to allow the insertion rod 5 to push the gas in the first slide groove 9 from the air inlet 14 into the first cavity 12, and then the fixed cone 11 is pushed into the ground. When the air inlet 14 needs to be sealed, the card plate 7 is in a state of being connected to the card slot 6. At this time, the card plate 7 will limit the position of the sealing block 13 at the air inlet 14 to seal the air inlet 14; when the sealing block 13 in the present application is driven by the card plate 7 to move to a position away from the air inlet 14, it will squeeze The elastic block 15, at this time, the gas in the elastic block 15 will enter the rectangular groove from the connecting pipe 18, thereby pushing the first sealing plate 17 to seal the first through hole 16. At this time, when the vertical rod 1 is hammered, the gas in the first slide groove 9 will only enter the first cavity 12. Then, when the first through hole 16 and the air inlet 14 need to be opened at the same time, it is only necessary to control the card plate 7 to push the sealing block 13 to move, so that the sealing block 13 no longer squeezes the elastic block 15. At this time, the first sealing plate 17 will be reset under the pull of the fourth spring, and will no longer seal the first through hole 16. At the same time, the position of the sealing block 13 and the air inlet 14 is staggered. Through the above mechanism, the first sealing plate 17 can be driven to seal the first through hole 16 in the process that the sealing block 13 does not seal the air inlet 14;

[0050] When the vertical pole 1 in the present application is used on a cement floor, the round rod 21 can be pushed to block the top of the plug rod 5 to prevent the first contact 19 from accidentally contacting the second contact 20 when the plug rod 5 is received in the first slide groove 9, thereby activating the alarm 4. When the safety protection fence is used on a cement floor, the location where it is generally located is not remote. When it is used on a mud floor, if it is in a remote place, wild animals may destroy the protection fence, causing the protection fence to fall down, and then destroy the wind farm box. When the safety protection fence in the present application is used in a remote wild area, it is necessary to first insert the plug rod 5 and the fixed cone 11 into the ground. At the end of this work, the first through hole 16 and the second through hole 24 both need to be in a sealed state, otherwise there will be gas circulation in the first slide groove 9, allowing the fixed cone 11 to be received in the second slide groove 10, and then the round rod 21 is pulled to allow the disc 23 to engage with the positioning groove 22. At this time, the round rod 21 no longer blocks the top of the plug rod 5, and the protection fence When the fence is destroyed and collapsed by wild animals, the upright pole 1 will tilt from the soil or be pulled out. When the upright pole 1 tilts in the soil, the resistance of the upright pole 1 to sliding in the soil will be greatly reduced. At this time, the sealing assembly will no longer seal the second through hole 24. At this time, the first spring will pull the plug rod 5, so that the plug rod 5 slides under the pull of the first spring, so that the first contact 19 contacts the second contact 20 to activate the alarm 4. At this time, the alarm 4 will sound and light alarm to scare away wild animals to prevent wild animals from continuing to damage the wind farm box; in the present application, if the upright pole 1 is damaged and tilted, the ball 27 will drive the second sealing plate 25 to move. As long as the second sealing plate 25 moves, the round hole on the second sealing plate 25 can move to the second through hole 24. At this time, the gas in the second slide groove 10 can flow normally, so that the first spring pulls the plug rod 5 to allow the first contact 19 to contact the second contact 20 to activate the alarm 4.
