Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection components, in particular to a lightning protection structure for a radio and television digital transmitter. Background Art

[0002] The application fields of the lightning protection structure of a radio and television digital transmitter mainly cover lightning protection of radio towers, lightning protection of equipment ports, lightning protection of power supply systems, etc. In the future, with the continuous development of technology, the development prospects of the lightning protection structure of digital transmitters will show trends such as technological innovation, application expansion, and standard formulation. Lightning arresters can prevent high-voltage surges caused by lightning from entering the equipment through the line. Equipping these components with special lightning protection devices can ensure normal operation during lightning weather. With the popularization of digital broadcasting, the application fields of the lightning protection structure will be further expanded.

[0003] In the prior art, during the installation of a lightning arrester, the minimum distance between the lightning arrester base and the ground shall not be less than 2.5 meters. This is to ensure that the gap discharge voltage does not decrease due to too close a distance, avoiding affecting the performance of the lightning arrester. However, in the face of the actual situation, the installation positions of some radio and television digital transmitters are relatively low, making it difficult to meet the requirements of the lightning arrester for the distance to the ground. This situation limits the application range of the lightning arrester, increases the difficulty of its deployment in specific environments, thus affecting the effectiveness of the overall lightning protection measures and endangering the normal operation and lifespan of the equipment. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a lightning protection structure for a radio and television digital transmitter.

[0005] To achieve the above object, the present utility model adopts the following technical solution: A lightning protection structure for a radio and television digital transmitter, comprising a lightning protection main body and a fixed substrate. A bottom column is fixed to the bottom of the fixed substrate, and a thin-diameter push column is fixed to the bottom of the lightning protection main body. Buckle grooves are linearly arrayed on the circumferential surface of the thin-diameter push column. A limiting rack is fixed to the bottom of the thin-diameter push column. A transmission gear is meshed with the surface of the limiting rack. A rotating plate is rotatably connected to the side of the transmission gear. A secondary sleeve column is fixed to one end of the rotating plate. A side groove is formed on the circumferential surface of the secondary sleeve column. An outer ring is fixed to the circumferential surface of the secondary sleeve column. A shaft fixing plate is fixed to the circumferential surface of the outer ring. An inclined rod is rotatably connected to one side of the shaft fixing plate. A round-head insert column is fixed to one end of the inclined rod. A return spring is fixed to the other end of the inclined rod. A power supply rack is meshed with the surface of the transmission gear. A base column is fixed to one end of the power supply rack. In the prior art, during the installation of the lightning arrester, the minimum distance between the lightning arrester base and the ground shall not be less than 2.5 meters. This is to ensure that the gap discharge voltage does not decrease due to too close a distance, avoiding affecting the performance of the lightning arrester. However, in the face of the actual situation, the installation positions of some radio and television digital transmitters are relatively low, making it difficult to meet the requirements of the lightning arrester for the ground distance. This situation limits the application range of the lightning arrester, increases the difficulty of its deployment in specific environments, thus affecting the effectiveness of the overall lightning protection measures and endangering the normal operation and lifespan of the equipment. To solve such problems, the present utility model adopts the method of installing a thin-diameter push column to achieve that when the installation position of the radio and television digital transmitter is relatively low, the staff can adjust the height of the lightning protection main body to meet the minimum distance requirement between the lightning arrester base and the ground. The staff presses the inclined rod to make the round-head insert column leave the buckle groove, and at the same time pulls the outer ring to make the secondary sleeve column move upward. The transmission gear meshes with the limiting rack and the power supply rack to rotate, pushing the thin-diameter push column upward to a suitable height. The staff releases the hand to make the round-head insert column enter the buckle groove corresponding to this height to fix the equipment. Through this structure, while using a smaller space, the elongation distance of the components can be increased, achieving the effect of improving the applicable range of the equipment.

[0006] Preferably, an upper top plate is fixed to the bottom of the base column, through holes are formed in the surface of the upper top plate, a fixed base circle is fixed to the top of the fixed base plate, a resilient column is fixed to the top of the fixed base circle, internal threads are formed in the inner wall of the resilient column, the circumferential surface of the resilient column is slidably connected to the inner wall of the through hole, an outward expanding ring is fixed to the top of the resilient column, and a screw is threadedly connected to the surface of the internal thread. In the prior art, radio and television digital transmitter equipment is usually installed at a relatively high position from the ground to promote the wide spread of signals. Although this high-altitude installation method has many advantages for signal coverage, it also brings certain challenges to the maintenance and installation of the equipment. When staff install components, they often need to use screws and other methods for fixation, and the fixation method with screws is prone to wear, resulting in a reduced service life of the equipment. To solve such problems, the present utility model adopts the method of installing a resilient column. When staff install, they only need to align the through hole with the resilient column for installation, then screw the screw into the internal thread to make the resilient column expand outward, and the outward expanding ring catches the upper top plate for fixation, achieving the effect of improving the service life of the equipment.

[0007] Preferably, a deceleration groove is formed at the bottom end of the auxiliary sleeve column, and a spring piece is fixed to the bottom end inner wall of the base column. In the prior art, when the moving speed of the auxiliary sleeve column exceeds the designed threshold, that is, when it moves downward too fast, a series of adverse consequences will occur. First of all, this rapid descent will reduce the interaction time between the auxiliary sleeve column and the base column, thereby reducing the buffering process, increasing the impact force when the two come into contact. Due to the lack of an effective buffering distance or time to gradually disperse and absorb the impact force, the collision between the auxiliary sleeve column and the base column will become inevitable. This direct and rapid collision will not only produce a significant sound but also cause an increase in the structural burden of the equipment, resulting in visible or invisible damage to the equipment. In this case, mechanical shock will cause wear, deformation or fracture of parts, further affecting the operation accuracy and efficiency of the equipment. In addition, frequent collisions will also accelerate material fatigue, shorten the service life of the equipment, and increase the maintenance cost. More seriously, if the collision is strong enough, it will damage the integrity of the equipment structure, even cause sudden failure or accident of the equipment, posing a threat to the safety of operators. To solve such problems, the present utility model adopts the method of installing a spring piece. When the auxiliary sleeve column moves rapidly downward, the spring piece first generates frictional force on its circumferential surface to decelerate, and when it contacts the deceleration groove, it is embedded in the deceleration groove to increase the buffering effect, achieving the effect of improving the service life of the equipment.

[0008] Preferably, stable triangles are fixedly arranged in a circumferential array on the top of the upper top plate to improve the stability of the base column, prevent the equipment from tilting, and improve the service life of the equipment.

[0009] Preferably, a fixing ring is fixed to the top of the resilient column to improve the fixing effect between the resilient column and the outward expanding ring.

[0010] Preferably, a rubber pad is fixed on the top of the fixed substrate to prevent the top of the fixed substrate from colliding with the bottom of the upper top plate, thereby enhancing the service life of the device.

[0011] Preferably, the top edge of the fixed base circle is rounded to prevent scratching the bottom of the upper top plate and improve the service life of the device.

[0012] Preferably, anti-slip grooves are provided at the bottom of the outward expansion ring to improve the fixing effect.

[0013] Preferably, a pressing plate is fixed at one end of the inclined rod to increase the contact area with the user's finger and improve the user experience.

[0014] Preferably, an arc-shaped cut is provided at the bottom of the pressing plate to prevent the sharp bottom from scratching the surface of the device and improve the service life of the device. Beneficial effects

[0015] 1. In the prior art, during the installation of a lightning arrester, the minimum distance between the lightning arrester base and the ground shall not be less than 2.5 meters. This is to ensure that the gap discharge voltage does not decrease due to too close a distance, so as to avoid affecting the performance of the lightning arrester. However, in reality, the installation positions of some radio and television digital transmitters are relatively low, making it difficult to meet the requirements of the lightning arrester for the distance to the ground. This situation limits the application range of the lightning arrester, increases the difficulty of its deployment in specific environments, thus affecting the effectiveness of the overall lightning protection measures and endangering the normal operation and service life of the equipment. To solve such problems, the present utility model adopts the method of installing a thin-diameter push column. When the installation position of the radio and television digital transmitter is relatively low, the staff can adjust the height of the lightning protection main body to meet the minimum distance requirement between the lightning arrester base and the ground. The staff presses the inclined rod to make the round-head insert column leave the buckle groove, and at the same time pulls the outer ring to make the auxiliary sleeve column move upward. The transmission gear meshes to limit the rotation of the rack and the force-supplying rack, and pushes the thin-diameter push column upward to a suitable height. Then the staff releases the hand to make the round-head insert column enter the buckle groove corresponding to this height to fix the device. Through this structure, the elongation distance of the component can be increased while using a smaller space, achieving the effect of expanding the applicable range of the device.

[0016] 2. In the prior art, radio and television digital transmitter equipment is usually installed at a relatively high position from the ground to facilitate the wide spread of signals. Although this high-altitude installation method has many advantages for signal coverage, it also poses certain challenges to the maintenance and installation of the equipment. When the staff installs the components, they often need to use screws or other methods for fixation, and the screw fixation method is prone to wear, resulting in a reduced service life of the equipment. To solve such problems, the present utility model adopts the method of installing a resilient column. When the staff installs, they only need to align the through hole with the resilient column for installation, and then screw the screw into the internal thread to make the resilient column expand outward. The outward expansion ring catches the upper top plate for fixation, achieving the effect of increasing the service life of the device.

[0017] 3. In the prior art, when the moving speed of the auxiliary sleeve column exceeds the design threshold, that is, when it moves downward too fast, a series of adverse consequences will occur. First of all, this rapid descent will reduce the interaction time between the auxiliary sleeve column and the base column, thereby reducing the buffering process, increasing the impact force when the two come into contact. Due to the lack of an effective buffering distance or time to gradually disperse and absorb the impact force, the collision between the auxiliary sleeve column and the base column will become inevitable. This direct and rapid collision will not only produce a significant sound but also increase the structural burden of the equipment, resulting in visible or invisible damage to the equipment. In this case, mechanical shock will cause wear, deformation or fracture of parts, further affecting the accuracy and efficiency of the equipment operation. In addition, frequent collisions will also accelerate material fatigue, shorten the service life of the equipment, and increase the maintenance cost. More seriously, if the collision is strong enough, it will damage the integrity of the equipment structure, even cause sudden failure or accident of the equipment, posing a threat to the safety of the operator. To solve such problems, the present utility model adopts the method of installing a spring plate, so that when the auxiliary sleeve column moves rapidly downward, the spring plate first generates frictional force on its peripheral surface to reduce the speed, and when it contacts the deceleration groove, it is embedded in the deceleration groove to increase the buffering effect, achieving the effect of improving the service life of the equipment.

However, the following embodiments are only the preferred embodiments of the present utility model and not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0029] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific embodiment

[0030] Refer to Figure 1-8, A lightning protection structure for a radio and television digital transmitter, including a lightning protection main body 1 and a fixed base plate 101. A bottom column 102 is fixed to the bottom of the fixed base plate 101, and a thin-diameter push column 2 is fixed to the bottom of the lightning protection main body 1. Clamping grooves 201 are linearly arrayed on the circumferential surface of the thin-diameter push column 2. A limiting rack 203 is fixed to the bottom of the thin-diameter push column 2. A transmission gear 207 meshes with the surface of the limiting rack 203. A rotating plate 206 is rotatably connected to the side of the transmission gear 207. A secondary sleeve column 204 is fixed to one end of the rotating plate 206. A side groove 205 is provided on the circumferential surface of the secondary sleeve column 204. An outer ring 2010 is fixed to the circumferential surface of the secondary sleeve column 204. A shaft fixing plate 2013 is fixed to the circumferential surface of the outer ring 2010. An inclined rod 2012 is rotatably connected to one side of the shaft fixing plate 2013. A round head insertion column 2011 is fixed to one end of the inclined rod 2012. A return spring 202 is fixed to the other end of the inclined rod 2012. A force supply rack 208 meshes with the surface of the transmission gear 207. A base column 209 is fixed to one end of the force supply rack 208. During the installation of the lightning arrester, the minimum distance between the lightning arrester base and the ground shall not be less than 2.5 meters. This is to ensure that the gap discharge voltage does not decrease due to too close a distance, avoiding affecting the performance of the lightning arrester. However, in the face of the actual situation, the installation positions of some radio and television digital transmitters are relatively low, making it difficult to meet the requirements of the lightning arrester for the ground distance. This situation limits the application range of the lightning arrester, increases the difficulty of its deployment in specific environments, thus affecting the effectiveness of the overall lightning protection measures and endangering the normal operation and lifespan of the equipment. The problem is solved by installing the thin-diameter push column 2. When the installation position of the radio and television digital transmitter is relatively low, the staff can adjust the height of the lightning protection main body 1 to meet the minimum distance requirement between the lightning arrester base and the ground. The staff presses the inclined rod 2012 to make the round head insertion column 2011 leave the clamping groove 201, and at the same time pulls the outer ring 2010 to make the secondary sleeve column 204 move upward. The transmission gear 207 meshes with the limiting rack 203 and the force supply rack 208 to rotate, pushing the thin-diameter push column 2 upward to an appropriate height. The staff releases the hand to make the round head insertion column 2011 enter the clamping groove 201 corresponding to this height to fix the equipment. Through this structure, the elongation distance of the components can be increased while using a smaller space, achieving the effect of expanding the applicable range of the equipment. Stable triangles 5 are circumferentially arrayed and fixed to the top of the upper top plate 103 to improve the stability of the base column 209, prevent the equipment from tilting, and extend the service life of the equipment. An arc-shaped cutout is provided at the bottom of the pressing plate 2014 to prevent the sharp bottom from scratching the surface of the equipment and extend the service life of the equipment.

[0031] At the bottom of the base column 209, there is a top plate 103 fixed. Through holes are provided on the surface of the top plate 103. At the top of the fixed base plate 101, a fixed base circle 3 is fixed. At the top of the fixed base circle 3, a resilient column 301 is fixed. An internal thread 302 is provided on the inner wall of the resilient column 301. The circumferential surface of the resilient column 301 is slidably connected to the inner wall of the through hole. At the top of the resilient column 301, an outward expansion ring 304 is fixed. A screw 305 is threadedly connected to the surface of the internal thread 302. Broadcast television digital transmitter equipment is usually installed at a relatively high position from the ground to promote the wide spread of signals. Although this high-altitude installation method has many advantages for signal coverage, it also brings certain challenges to the maintenance and installation of the equipment. When staff install components, they often need to use methods such as screws 305 for fixation. However, the fixation method of screws 305 is prone to wear, resulting in a reduction in the service life of the equipment. This is solved by adopting the method of installing the resilient column 301. When staff install, they only need to align the through hole with the resilient column 301 for installation, then screw the screw 305 into the internal thread 302, causing the resilient column 301 to expand outward, and the outward expansion ring 304 to clamp the top plate 103 for fixation, achieving the effect of improving the service life of the equipment. At the bottom end of the auxiliary sleeve column 204, a deceleration groove 4 is provided. At the bottom end of the inner wall of the base column 209, a spring piece 401 is fixed. When the moving speed of the auxiliary sleeve column 204 exceeds the designed threshold, that is, when it moves downward too fast, a series of adverse consequences will occur. First of all, this rapid descent will reduce the interaction time between the auxiliary sleeve column 204 and the base column 209, thereby reducing the buffering process, increasing the impact force when the two come into contact. Due to the lack of an effective buffering distance or time to gradually disperse and absorb the impact force, the collision between the auxiliary sleeve column 204 and the base column 209 will become inevitable. This direct and rapid collision will not only produce a significant sound but also cause an increase in the structural burden of the equipment, resulting in visible or invisible damage to the equipment. In this case, mechanical shock will cause wear, deformation or fracture of components, further affecting the accuracy and efficiency of the equipment operation. In addition, frequent collisions also accelerate material fatigue, shorten the service life of the equipment, and increase the maintenance cost. More seriously, if the collision is strong enough, it will damage the integrity of the equipment structure, even cause sudden failure or accident of the equipment, posing a threat to the safety of the operator. This is solved by adopting the method of installing the spring piece 401. When the auxiliary sleeve column 204 moves rapidly downward, the spring piece 401 first generates frictional force on its circumferential surface for deceleration, and when it contacts the deceleration groove 4, it is embedded in the deceleration groove 4 to increase the buffering effect, achieving the effect of improving the service life of the equipment. At the top of the resilient column 301, a fixing ring 303 is fixed to improve the fixing effect between the resilient column 301 and the outward expansion ring 304. At the top of the fixed base plate 101, a rubber pad is fixed to prevent the top of the fixed base plate 101 from colliding with the bottom of the top plate 103, improving the service life of the equipment. The top edge of the fixed base circle 3 is rounded to prevent scratching the bottom of the top plate 103, improving the service life of the equipment. The bottom of the outward expansion ring 304 is provided with an anti-slip groove to improve the fixing effect.One end of the diagonal rod 2012 is fixed with a pressing plate 2014, which increases the contact area with the user's finger and improves the user experience.

[0032] The working principle of the present utility model: When the installation position of the radio and television digital transmitter is relatively low, the staff can adjust the height of the lightning protection main body 1 to meet the minimum distance requirement between the lightning arrester base and the ground. The staff presses the diagonal rod 2012 to make the round head insert post 2011 leave the buckle groove 201. At the same time, the outer ring 2010 is pulled to make the secondary sleeve post 204 move upward. The transmission gear 207 meshes to limit the rotation of the limit rack 203 and the power supply rack 208, and pushes the thin-diameter push post 2 upward to a suitable height. The staff releases the hand to make the round head insert post 2011 enter the buckle groove 201 corresponding to this height to fix the device. Through this structure, the elongation distance of the component can be increased while using a smaller space. When the staff installs, only need to align the through hole with the ductile column 301 for installation, and then screw the screw 305 into the internal thread 302 to make the ductile column 301 expand outward, and the outer expansion ring 304 catches the upper top plate 103 for fixation.
