[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) When the photovoltaic transformer is hit, it will first contact the buffer pad on the collision horizontal plate, avoiding damage to the collision horizontal plate caused by a strong impact force, thereby increasing the service life of the collision horizontal plate. At the same time, the buffer force brought by the buffer pad initially reduces the impact force of the collision. Under the action of the first hinged square seat, the hinged square plate and the second hinged square seat, the two guide blocks move relative to each other on the guide square column, so that the guide spring is in a buffering state. At the same time, the moving collision horizontal plate moves relative to the main body through the positioning cylinder on the T-shaped square plate, so that the positioning spring is also in a buffering state. The above-mentioned buffer forces can reduce the impact of the main body. The impact force brought by the collision can absorb the energy brought by the collision and convert the kinetic energy of the collision into elastic potential energy, thereby reducing the impact force transmitted to the inside of the body, effectively protecting the internal structural parts of the body or itself from damage caused by severe impact, and improving the service life of the photovoltaic transformer. At the same time, the collision cross plate is used to limit the movement of the collision cross plate through a number of guide square columns to avoid dislocation or shaking of the collision cross plate after the collision, thereby improving the stability of the collision cross plate when moving, further improving the use effect of the photovoltaic transformer, and reducing the limitations of the machine when in use;

[0016] (2) Suction is generated in the hollow square box, and the gas in the body is sucked into the hollow square box through the air inlet; when the pressure plate moves close to the ventilation square groove, the second switch valve is closed and the first switch valve is opened, so that the gas absorbed in the hollow square box is discharged through the ventilation square groove, which can not only dissipate the heat in the body and discharge the heat in the body, but also avoid the body from accumulating too much internal heat and causing explosion due to large friction or other non-human factors after being hit, and at the same time avoid fire caused by excessive temperature. It is worth mentioning that the pressure in the body can be reduced in the process, and the deformation of the body after being hit, which makes the internal space smaller and causes pressure rise, can also avoid the risk of explosion due to high temperature and high pressure inside the body when it is hit, thereby improving the use effect of the photovoltaic transformer and avoiding the machine from having strong safety hazards when in use;

[0017] (3) The displacement inclined block moves so that its inclined surface contacts the pressure wheel, thereby providing a downward force to the pressure wheel, so that the U-shaped square seat on the pressure wheel moves on the main body through the pressure square column, so that the pressure spring is in a buffering state, and then drives the pressure cross block on the bottom surface of the main body to move away from the main body. Under the action of the limiting square tube, the limiting square column and the limiting spring, the pressure block is driven to move toward the ground and contact it, so that the rubber square pad on the pressure block also contacts the ground, further increasing the friction between the pressure block and the ground, supporting the main body, avoiding displacement or dislocation when it is hit, and dispersing the impact suffered by the main body to a certain extent. The force is transmitted to the ground through the contact between the pressure block and the ground, further consuming the energy generated by the impact, thereby reducing the impact on the main body. The stronger the impact on the main body, the more the limiting square tube moves within the limiting square column, making the limiting spring in a buffering state, thereby further strengthening the contact between the pressure block and the ground, improving the stability of the main body during use, and further avoiding the movement of the main body after being hit, which causes the deviation of the installation position of the main body, reducing the work intensity of the staff, and at the same time reducing the limitations of the machine during use, so that the effect of the photovoltaic transformer during use is improved;

[0018] (4) When the impact force is too great, the displacement protrusion on the T-shaped square plate will enter the displacement recessed box, and then the displacement recessed box and the sensor sheet on the displacement protrusion will contact, thereby sending a signal to the control unit. After receiving the signal, the control unit indicates that the impact force is too great and the degree of damage to the body is also strong, so a signal is sent to notify the operator, so that the operator can maintain or rescue the body in time, thereby improving the use effect of the transformer;

[0019] (5) When the U-shaped square seat moves downward, it will also drive the fixed seat to move. Under the action of the cable, the cable roller is in a state of paying out and rotating, thereby driving the driving shaft to rotate, so that the spring is in a buffer state, so that it can drive the cable roller to wind the cable when it is reset. At the same time, when the impact force reaches the maximum and gradually decreases, when it is less than the sum of several buffer forces in the device, several buffers in the device are gradually reset, thereby providing an opposite force to the direction of the impact, which can effectively absorb the remaining impact energy and greatly reduce the damage to the main body and other parts connected to it, thereby releasing the energy stored in the main body after the impact, avoiding the need for manual reset at the next impact, which affects the normal use of the main body and improves the service life of the main body;

[0020] (6) driving the stop square column to move so that the stop square plate on it contacts the collision horizontal plate moved by the impact, providing an opposite force to the moving collision horizontal plate, supporting the collision horizontal plate on all sides, avoiding the collision horizontal plate from being strongly deformed when impacted, further reducing the damage to the main body caused by the impact, and limiting the movement of the collision horizontal plate to avoid the collision horizontal plate from contacting the side of the main body due to excessive impact force, thereby improving the use effect of the main body and reducing the safety hazards of the photovoltaic transformer during use. At the same time, the buffering force brought by the auxiliary spring further reduces the impact force on the main body. It is worth mentioning that a pressure sensor can be provided on the stop square plate to monitor the impact force and monitor the condition of the main body in real time, thereby reducing the limitations of the photovoltaic transformer during use.

A second hinged square seat 14 is hingedly installed on one end of the hinged square plate 13 away from the first hinged square seat 12. The two hinged square plates 13 are arranged in an outward-facing shape; guide blocks 15 are installed on the two second hinged square seats 14, and a guide square column 16 is slidably provided on the two guide blocks 15; guide base plates 17 are installed at both ends of the guide square column 16, and the guide base plate 17 is arranged on the sound insulation square plate 3; guide springs 18 are symmetrically sleeved on the guide square column 16, and one end of the guide spring 18 is connected to the guide base plate 17, and the other end of the guide spring 18 is connected to the guide base plate 17. One end is connected to the guide square block 15; a buffer square pad 19 is installed on the side of the collision horizontal plate 4 away from the body 1; a positioning spring 36 is sleeved on the positioning cylinder 6, one end of the positioning spring 36 is fixedly connected to the T-shaped square plate 5, and the other end is fixedly connected to the side of the body 1; a displacement protrusion 37 is installed on the side of the T-shaped square plate 5 close to the body 1, and a displacement concave box 38 is provided on the moving path of the displacement protrusion 37, and the displacement concave box 38 is arranged on the body 1; a sensor sheet 39 is provided on the inner bottom surface of the displacement concave box 38 and the displacement protrusion 37, and the displacement concave box 38 and the displacement protrusion 37 fit together;

[0037] After the main body 1, i.e., the photovoltaic transformer, is fixed to the desired place, the sound insulation square plate 3, i.e., the collision energy absorption mechanism, is fixed to the four sides of the photovoltaic transformer by bolts for use; when the placed photovoltaic transformer is hit, it will first contact the buffer square pad 19 on the collision horizontal plate 4 to avoid damage to the collision horizontal plate 4 caused by a strong impact force, thereby increasing the service life of the collision horizontal plate 4. At the same time, the buffering force brought by the buffer square pad 19 initially reduces the impact force of the collision. Under the action of the first hinged square seat 12, the hinged square plate 13 and the second hinged square seat 14, the two guide blocks 15 are relatively moved on the guide square column 16, so that the guide spring 18 is in a buffering state. At the same time, the moving collision horizontal plate 4 is moved relative to the main body 1 through the positioning cylinder 6 on the T-shaped square plate 5, so that the positioning spring 36 is also in a buffering state. The above-mentioned buffering forces can reduce the impact force brought by the main body 1 when it is hit, thereby absorbing the energy brought by the impact and converting the kinetic energy of the impact into elastic potential energy, thereby The impact force transmitted to the inside of the body 1 is reduced, and the internal structural parts of the body 1 or the body itself are effectively protected from damage caused by severe impact, thereby prolonging the service life of the photovoltaic transformer. At the same time, the collision cross plate 4 is used to limit the movement of the collision cross plate 4 through a plurality of guide square columns 16, so as to avoid dislocation or shaking of the collision cross plate 4 after the collision, thereby improving the stability of the collision cross plate 4 during movement, further improving the use effect of the photovoltaic transformer, and reducing the limitations of the machine during use; it is worth mentioning that when the impact force is too large, the displacement protrusion 37 on the T-shaped square plate 5 will enter the displacement recessed box 38, and then the displacement recessed box 38 and the sensor sheet 39 on the displacement protrusion 37 will contact, thereby sending a signal to the control unit. After receiving the signal, the control unit indicates that the impact force is too large, resulting in a strong degree of damage to the body 1, and thus sends a signal to notify the operator, so that the operator can timely maintain or rescue the body 1, thereby improving the use effect of the transformer.

[0038] The downward pressure energy dissipation component of the present embodiment also includes a U-shaped square seat 20 arranged on the pressure wheel 9, and a fixing seat 21 is symmetrically arranged on the U-shaped square seat 20, and a cable 22 is connected to the fixing seat 21, and the cable 22 is wound on a cable roller 23, and two cable rollers 23 are arranged on the driving shaft 10; a driving substrate 24 is symmetrically arranged on the driving shaft 10, and the driving substrate 24 is fixed on the inner top surface of the heat dissipation cavity 2; a clockwork spring 25 is symmetrically arranged on the driving shaft 10, and the end point of the clockwork spring 25 is arranged on the driving substrate 24; a driving gear 26 is also symmetrically arranged on the driving shaft 10, and the driving gear 26 is meshed with a driving rack 27, and a fitting stopper is arranged on the driving rack 27; the U-shaped A pressure square column 28 is fixed on the bottom surface of the square seat 20, and a pressure cross block 29 is installed on the end point of the pressure square column 28 that passes through the bottom surface of the main body 1. A limiting square cylinder 30 is symmetrically arranged on the bottom surface of the pressure cross block 29 away from the main body 1.

[0039] When the body 1 is hit, the collision cross plate 4 moves, thereby driving the displacement inclined block 8 to move, so that its inclined surface contacts the pressure wheel 9, thereby providing a downward force to the pressure wheel 9, so that the U-shaped square seat 20 on the pressure wheel 9 moves on the body 1 through the pressure square column 28, so that the pressure spring 35 is in a buffering state, and then drives the pressure cross block 29 on the bottom surface of the body 1 to move away from the body 1, and drives the pressure block 32 to move toward the ground and contact it under the action of the limiting square cylinder 30, the limiting square column 31 and the limiting spring 34, so that the rubber square on the pressure block 32 The pad 33 is also in contact with the ground, further increasing the friction between the pressure block 32 and the ground, supporting the body 1 to prevent displacement or dislocation when it is hit, and dispersing the impact force suffered by the body 1 to a certain extent. The contact between the pressure block 32 and the ground transfers part of the energy to the ground, further consuming the energy generated by the impact, thereby reducing the impact on the body 1. The stronger the impact force suffered by the body 1, the more the limiting square tube 30 moves in the limiting square column 31, so that the limiting spring 34 is in a buffering state, thereby further increasing the impact. The contact force of the strong pressure block 32 with the ground improves the stability of the main body 1 during use, further avoids the movement of the main body 1 after being hit, etc., which causes the deviation of the installation position of the main body 1, reduces the work intensity of the staff, and reduces the limitations of the machine during use, so that the effect of the photovoltaic transformer during use is improved; it is worth mentioning that when the U-shaped square seat 20 moves downward, it will also drive the fixed seat 21 to move. Under the action of the cable 22, the wire roller 23 is in a state of wire release and rotation, thereby driving the driving shaft 10 to rotate, so that the spring spring 25 is in a buffering state, so that it can drive the wire roller 23 to wind the cable 22 when it is reset. At the same time, when the impact force reaches the maximum and gradually decreases, when it is less than the sum of several buffer forces in the device, several buffers in the device are gradually reset, thereby providing an opposite force to the direction of the impact, which can effectively absorb the remaining impact energy, greatly reduce the damage to the main body 1 and other components connected thereto, thereby releasing the energy stored in the main body 1 after the impact, avoiding the need for manual reset at the next impact, which affects the normal use of the main body 1, and improves the service life of the main body 1.

Under the action of the return spring 52, the touch cross block 43 will continuously reciprocate on the return base plate 45 through the return cylinder 44, thereby driving the pressure square plate 51 to reciprocate and move inside the hollow square box 46; when the pressure square plate 51 moves away from the ventilation square groove 47, the first switch valve 48 inside it is closed, and the second switch valves 50 are opened, so that suction is generated in the hollow square box 46, and the gas in the body 1 is sucked into the hollow square box 46 through the air inlet 49; when the pressure square plate 51 moves close to the ventilation square groove 47 When the second switch valve 50 is closed, the first switch valve 48 is opened, so that the gas absorbed in the hollow square box 46 is discharged through the ventilation square groove 47, which can not only dissipate the heat in the main body 1, but also discharge the heat in the main body 1, so as to avoid the main body 1 from accumulating too much internal heat and causing explosion due to large friction or other non-human factors after being hit, and at the same time avoid fire caused by excessive temperature. It is worth mentioning that in this process, the pressure in the main body 1 can be reduced, and the deformation of the main body 1 after being hit, which makes the internal space smaller and causes pressure increase, can be avoided, and the risk of explosion due to high temperature and high pressure inside the main body 1 when it is hit can be avoided, thereby improving the use effect of the photovoltaic transformer and avoiding the machine from having strong safety hazards when in use.

[0042] The fitting stopper of this embodiment includes an auxiliary sliding column 53 arranged on the driving rack 27, on which an auxiliary base 54 slides, and the auxiliary base 54 is fixed to the inner top surface of the heat dissipation cavity 2; the driving rack 27 is also equipped with a fitting U rod 55 on the side close to the collision horizontal plate 4, and the fitting U rod 55 passes through the side of the body 1 and the sound insulation square plate 3; the opening of the fitting U rod 55 faces the collision horizontal plate 4 and an auxiliary sliding groove 56 is opened on the end point, and a stop square column 57 slides on the auxiliary sliding groove 56, and a stop square plate 58 is installed on the end of the stop square column 57 close to the collision horizontal plate 4; an auxiliary spring 59 is arranged in the auxiliary sliding groove 56, one end of the auxiliary spring 59 is connected to the stop square column 57, and the other end is connected to the inner bottom surface of the auxiliary sliding groove 56;

[0043] When the driving shaft 10 rotates, it drives the two driving gears 26 to rotate, so that the meshing driving rack 27 moves, so that the rack moves on the auxiliary base 54 through the auxiliary sliding column 53, thereby driving the fitting U rod 55 to move, so that it passes through the side of the body 1 and the sound insulation square plate 3, and moves, and drives the stop square column 57 to move under the action of the auxiliary spring 59, so that the stop square plate 58 on it contacts the collision cross plate 4 moved by the collision, and provides an opposite force to the moving collision cross plate 4, supports the collision cross plate 4 around, and prevents the collision cross plate 4 from being generated when it is hit. The stronger deformation further reduces the damage to the main body 1 caused by the impact, and at the same time limits the movement of the collision cross plate 4 to avoid excessive impact force causing the collision cross plate 4 to contact the side of the main body 1, thereby improving the use effect of the main body 1 and reducing the safety hazard of the photovoltaic transformer during use. At the same time, the buffering force brought by the auxiliary spring 59 further reduces the impact force on the main body 1. It is worth mentioning that a pressure sensor can be provided on the stop square plate 58 to monitor the impact force and monitor the situation of the main body 1 in real time, reducing the limitations of the photovoltaic transformer during use.
