Choosing a suitable antenna mounting bracket is crucial to ensuring the performance and stability of the antenna.

[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 making creative work are within the scope of protection of the present invention.

[0040] like Figures 1 to 8 As shown, an installation bracket for a communication antenna provided by an embodiment of the present invention includes a support rod 100 , a fixing seat 200 , a clamping mechanism 300 and an angle adjustment mechanism 400 .

[0041] The support rod 100 extends vertically; at least two fixing seats 200 are provided, and the plurality of fixing seats 200 are arranged at intervals along the extension direction of the antenna body 500 and are fixedly connected to the antenna body 500 .

[0042] The number of the clamping mechanisms 300 is consistent with the number of the fixing seats 200, and the multiple clamping mechanisms 300 are arranged at intervals in the vertical direction; the clamping mechanism 300 includes a shell and a clamping member 320; there are two shells, and the two half shells 310 are arranged along the radial direction of the support rod 100 and are located on both sides of the support rod 100; the two half shells 310 are enclosed outside the support rod 100 to form a whole, and the two half shells 310 are connected by a connecting member 330, and the connecting member 330 is used to adjust the distance between the two half shells 310, and the connecting member 330 includes a bolt and a nut; each half shell 310 is provided with a mounting groove 311 on the side facing the support rod 100, and the mounting groove 311 is arc-shaped; a clamping member 320 is fixedly connected to each mounting groove 311, and the interior of the clamping member 320 is hollow, defining a accommodating cavity 322, and the side of the clamping member 320 facing the support rod 100 is a clamping surface 321, and the clamping surface 321 is an arc surface and can undergo elastic deformation.

[0043] An adjusting chamber 313 is provided in the half shell 310, and each accommodating chamber 322 is connected to an adjusting chamber 313. A pre-stress piston 340 is slidably installed in the adjusting chamber 313. The pre-stress piston 340 divides the adjusting chamber 313 into a first chamber and a second chamber. The first chamber is connected to the accommodating chamber 322. The first chamber and the accommodating chamber 322 are filled with liquid, and the internal pressure is greater than the atmospheric pressure. A pre-stress spring 350 is connected between the pre-stress piston 340 and the half shell 310. In the initial state, the pre-stress spring 350 has an elastic force that causes the pre-stress piston 340 to move toward the accommodating chamber 322.

[0044] The angle adjustment mechanism 400 is disposed between the uppermost fixing seat 200 and the uppermost clamping mechanism 300 . The angle adjustment mechanism 400 is used to adjust the angle between the antenna body 500 and the support rod 100 .

[0045] When in use, the distance between the two half shells 310 in the same clamping mechanism 300 is adjusted by the connecting piece 330, and the angle between the antenna body 500 and the support rod 100 is adjusted by the angle adjustment mechanism 400 until the angle between the two reaches a preset value; the accommodating chamber 322 is filled with liquid, and the volume thermal expansion coefficient of the liquid is small, such as mercury, pure water, glycerin, etc.; the pre-stress spring 350 applies a force to the pre-stress piston 340, and the force is equal to the pressure in the accommodating chamber 322 in the initial state, so the pre-stress piston 340 remains stationary in the adjustment chamber 313; because the pressure in the accommodating chamber 322 is greater than the atmospheric pressure, there is a pressure difference between the inner and outer sides of the clamping surface 321, so the clamping surface 321 bulges toward the support rod 100 to fix the half shell 310 on the support rod 100.

[0046] When the ambient temperature of the antenna body 500 changes, the liquid in the accommodating cavity 322 expands and contracts. When the temperature rises, the pressure in the accommodating cavity 322 increases, the bulging degree of the clamping surface 321 increases, and the clamping force of the clamping member 320 on the support rod 100 increases. At the same time, the pressure in the accommodating cavity 322 pushes the pre-stressing piston 340 to move away from the accommodating cavity 322, thereby increasing the volume of the pre-stressing piston 340 toward the accommodating cavity 322, thereby reducing the pressure in the accommodating cavity 322, reducing the bulging degree of the clamping surface 321, and thereby reducing the clamping force of the clamping member 320 on the support rod 100. holding force, avoiding damage to the support rod 100 or the clamping member 320 due to excessive clamping force; when the temperature drops, the pressure in the accommodating chamber 322 decreases, the bulging degree of the clamping surface 321 decreases, and the clamping force of the clamping member 320 on the support rod 100 decreases. At the same time, the elastic force of the pre-stressing spring 350 causes the pre-stressing piston 340 to move toward the accommodating chamber 322, thereby increasing the pressure in the accommodating chamber 322, increasing the bulging degree of the clamping surface 321, and then increasing the clamping force of the clamping member 320 on the support rod 100, avoiding the problem of poor stability and tipping of the antenna body 500 due to excessively small clamping force.

[0047] The present invention provides an elastically deformable clamping member 320, a pre-stressing piston 340 and a pre-stressing spring 350, and utilizes the pre-stressing piston 340 and the pre-stressing spring 350 to adjust the pressure inside the clamping member 320, thereby adjusting the clamping force. This alleviates the problem of changes in the clamping force caused by thermal expansion and contraction due to changes in the ambient temperature of the antenna body 500 to a certain extent, and solves the problem of damage to the clamping member 320 or the support rod 100 due to excessive clamping force caused by temperature increase, and the problem of poor stability and tipping of the antenna body 500 due to excessive clamping force caused by temperature decrease.

[0048] In a further embodiment, Figure 3 , Figure 5 , Figure 7 As shown, the first chamber and the accommodating chamber 322 are connected to form a sealed chamber, and the second chamber is connected to a pressure regulating mechanism 600, which is used to adjust the pressure in the second chamber so that the elastic force of the preload spring 350 and the cooperative force of the second chamber on the pressure of the preload piston 340 are equal to the initial pressure of the sealed chamber on the preload piston 340, and the direction is opposite. The preload piston 340 is subjected to balanced force and remains stationary in the regulating chamber 313.

[0049] When the temperature of the environment in which the clamping member 320 is located increases, the liquid in the sealing chamber expands, and the pressure of the sealing chamber on the pre-stress piston 340 increases, which is greater than the sum of the pressure of the second chamber on the pre-stress piston 340 and the elastic force of the pre-stress spring 350. At this time, the pressure difference on the pre-stress piston 340 causes the pre-stress piston 340 to move away from the accommodating chamber 322. As the pre-stress piston 340 moves, the volume of the sealing chamber increases and the pressure therein decreases. When the pressure in the sealing chamber reaches the initial pressure value again, the pre-stress piston 340 is balanced and remains stationary, thereby adjusting the clamping force to the preset value.

[0050] When the temperature of the environment in which the clamping member 320 is located decreases, the liquid in the sealing chamber contracts, and the pressure of the sealing chamber on the pre-stress piston 340 decreases, which is less than the sum of the pressure of the second chamber on the pre-stress piston 340 and the elastic force of the pre-stress spring 350. At this time, the pressure difference on the pre-stress piston 340 causes the pre-stress piston 340 to move toward the accommodating chamber 322. As the pre-stress piston 340 moves, the volume of the sealing chamber decreases and the pressure therein increases. When the pressure in the sealing chamber reaches the initial pressure value again, the pre-stress piston 340 is subjected to force balance and remains stationary.

[0051] The pressure in the accommodating chamber 322 is kept constant by the pre-compression piston 340 and the pressure regulating mechanism 600, so that the clamping force of the clamping member 320 on the support rod 100 is kept constant, thereby solving the problem of damage or stability affected by thermal expansion and contraction.

[0052] In a further embodiment, Figure 3 As shown, a wind speed detection component 700 and a control system are provided on the shell. The wind speed detection component 700 is used to detect the magnitude of the wind speed and transmit the numerical value to the control system; the control system transmits the instruction to the pressure regulating mechanism 600. The greater the wind speed, the greater the pressure in the second chamber is made by the pressure regulating mechanism 600.

[0053] When the wind speed in the environment where the clamp 320 is located changes, the wind speed detection component 700 detects the value and transmits it to the control system, and the control system uses the pressure adjustment mechanism 600 to adjust the pressure in the second chamber.

[0054] When the wind speed increases, the control system uses the pressure regulating mechanism 600 to increase the pressure in the second chamber, thereby using the pressure difference on the pre-stress piston 340 to move the pre-stress piston 340 toward the accommodating chamber 322, increasing the pressure in the sealed chamber, and further increasing the bulging degree of the clamping member 320, thereby increasing the clamping force of the clamping member 320 on the support rod 100, thereby preventing the antenna body 500 from tipping over due to insufficient clamping force due to excessive wind speed, thereby affecting the communication quality.

[0055] When the wind speed decreases, the control system uses the pressure regulating mechanism 600 to reduce the pressure in the second chamber, and the pre-compression piston 340 moves away from the accommodating chamber 322 under the action of the pressure difference, increasing the volume of the sealed chamber and reducing the pressure therein, thereby reducing the bulging degree of the clamping member 320 and reducing the clamping force of the clamping member 320 on the support rod 100, thereby avoiding damage caused by the clamping force being maintained at a large value for a long time. The present invention can automatically adjust the clamping force of the clamping member 320 on the support rod 100 according to the size of the wind speed in the environment.

[0056] In a further embodiment, Figure 3 , Figure 6 , Figure 8 As shown, the pressure regulating mechanism 600 includes a liquid storage box 610, a regulating piston 620 and a driving assembly 630. The liquid storage box 610 is arranged in the half shell 310. The liquid storage box 610 is connected to the second cavity through a pipeline. The liquid storage box 610 is filled with liquid. The regulating piston 620 can be slidably installed in the liquid storage box 610. The driving assembly 630 is used to drive the regulating piston 620 to slide.

[0057] In the initial state, the pipeline and the second cavity are filled with liquid, and the control system uses the driving component 630 to keep the pressure in the pipeline and the second cavity at a preset value, which is equal to the pressure in the sealing cavity in the initial state.

[0058] When the wind speed increases, the control system transmits information to the drive component 630, and the drive component 630 drives the regulating piston 620 to move downward, squeezing the liquid in the liquid storage box 610 into the pipeline, thereby increasing the pressure in the pipeline and the second chamber, and moving the pre-load piston 340 toward the accommodating chamber 322, thereby increasing the pressure in the accommodating chamber 322, and increasing the clamping force of the clamp 320 on the support rod 100.

[0059] When the wind speed decreases, the control system transmits information to the drive component 630, and the drive component 630 drives the regulating piston 620 to move upward, so that the liquid in the pipeline and the second chamber flows back to the liquid storage box 610, thereby reducing the pressure in the pipeline and the second chamber. Under the action of the pressure difference, the pre-pressure piston 340 moves away from the accommodating chamber 322, and the pressure in the accommodating chamber 322 is reduced, thereby reducing the clamping force of the clamp 320 on the support rod 100.

[0060] In a further embodiment, Figure 6 , Figure 8 As shown, the driving assembly 630 includes a driving motor 631, a driving gear 632 and a driving rack 633; ​​the driving rack 633 is fixedly connected to the adjusting piston 620, the driving motor 631 is installed in the half shell 310, the driving gear 632 is synchronously connected to the output end of the driving motor 631, and the driving gear 632 is meshed with the driving rack 633. A dust cover is provided on one side of the clamping mechanism 300 where the switching motor 661 and the driving motor 631 are installed.

[0061] When the wind speed increases, the control system starts the drive motor 631, thereby driving the drive gear 632 to rotate counterclockwise. When the drive gear 632 rotates, it drives the drive rack 633 to move downward, and then drives the regulating piston 620 to move downward, pressing the liquid in the liquid storage box 610 into the pipeline.

[0062] When the wind speed decreases, the control system starts the drive motor 631 to drive the drive gear 632 to rotate clockwise, thereby driving the drive rack 633 to move upward, and the regulating piston 620 moves upward synchronously with the drive rack 633 to draw the liquid in the pipeline into the liquid storage box 610.

[0063] In a further embodiment, Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a plurality of clamping members 320 and a plurality of regulating chambers 313 are provided in each half shell 310; the plurality of clamping members 320 are evenly distributed along the vertical direction; the liquid storage box 610 is connected to a distribution channel 640, and the plurality of regulating chambers 313 are respectively connected to the distribution channel 640 through pipes, and the plurality of pipes are distributed circumferentially along the distribution channel 640; a valve 650 is installed between the distribution channel 640 and the liquid storage box 610, and the valve 650 can be rotatably installed on the distribution channel 640 around its own axis; the water inlet of the valve 650 is connected to the liquid storage box 610, and the water outlet of the valve 650 extends radially along the distribution channel 640, and the valve 650 is connected to a switching assembly 660, and the switching assembly 660 is used to drive the valve 650 to rotate circumferentially.

[0064] When the wind force increases, the control system starts the switching component 660, and through the switching component 660, the water outlet of the valve 650 is directed toward the pipe connected to the top clamping member 320. Then the control system starts the driving motor 631, and the driving motor 631 drives the driving gear 632 to rotate. When the driving gear 632 rotates, it drives the driving rack 633 to move downward, and the regulating piston 620 presses the liquid in the liquid storage basin into the pipe, so that the pressure in the receiving groove of the top clamping member 320 increases, thereby increasing the clamping force of the top clamping member 320.

[0065] After the clamping force of the uppermost clamping member 320 increases to a preset value, the control system starts the switching assembly 660 again, so that the water outlet of the valve 650 faces the pipe connected to the next clamping member 320, thereby increasing the clamping force of the next clamping member 320, and so on.

[0066] When the wind speed decreases, the direction of the water outlet of the valve 650 is switched by the switching assembly 660, so that one of the clamping members 320 maintains a relatively large clamping force, and the clamping forces of the other clamping members 320 are restored to the initial state. When the wind force changes multiple times, the control system allows multiple clamping members 320 to provide a large clamping force in turn, thereby continuously changing the position where the clamping force is applied, solving the problem that the clamping member 320 at a fixed clamping position becomes loose under the action of long-term external forces, and the clamping force is too small to cause poor stability of the mounting bracket. When adjusting the position where the clamping force is applied, the clamping force can be adjusted to the required size, further providing stability.

[0067] In a further embodiment, Figure 3 , Figure 6 , Figure 8 As shown, the switching assembly 660 includes a switching motor 661, a driving wheel 662, a driven wheel 663 and a belt 664; the switching motor 661 is installed on the half shell 310, the driving wheel 662 is connected to the output end of the switching motor 661, and the driven wheel 663 is synchronously connected to the valve 650, and the driving wheel 662 and the driven wheel 663 are driven by a belt 664.

[0068] When it is necessary to switch the direction of the water outlet of valve 650, the control system rotates the switching motor 661. When the switching motor 661 rotates, it drives the driving wheel 662 to rotate synchronously. The driving wheel 662 drives the driven wheel 663 to rotate through the belt 664, thereby causing the valve 650 to rotate around its own axis, and finally adjusting the direction of the water outlet.

[0069] In a further embodiment, Figure 1 , Figure 2 As shown, the angle adjustment mechanism 400 includes a first connecting rod 410, a second connecting rod 420 and a fixed rod 430; one end of the first connecting rod 410 is rotatably mounted on the fixed seat 200, and the other end is rotatably mounted on the second connecting rod 420, and the end of the second connecting rod 420 away from the first connecting rod 410 is rotatably mounted on the half shell 310; one end of the fixed rod 430 is rotatably mounted on the first connecting rod 410, and the other end extends toward the second connecting rod 420, a plurality of fixing holes are provided on the fixing rod 430, and a plug hole is provided on the second connecting rod 420, the fixing holes can overlap with the plug hole, and a fixing pin is inserted in the plug hole.

[0070] When it is necessary to adjust the angle of the antenna body 500, pull the fixing pin out from the socket to rotate the first connecting rod 410, the second connecting rod 420 and the fixing rod 430, select a suitable fixing hole to coincide with the socket according to the required angle between the antenna body 500 and the support rod 100, and then insert the fixing pin into the socket and the fixing hole that coincides with it, so that the angle between the antenna body 500 and the support rod 100 remains unchanged.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
