DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In the present embodiment, a flood control emergency communication device is provided, which utilizes a lifting assembly 2 installed on the upper end of a base 1 to drive an antenna 11 to perform lifting movement, so as to adjust the height position of the antenna 11; then, driven by a rotating assembly 3, a rotating motor 32 drives a first gear 33 to drive a second gear 36 to rotate in coordination, so that a mounting seat 35 can drive the antenna 11 to rotate in a horizontal direction, and then the angle at which the antenna 11 receives communication signals can be adjusted to meet different communication requirements; through the synergistic effect of the lifting assembly 2 and the rotating assembly 3, the antenna 11 can adjust its position height and the angle at which it receives signals in response to different weather and environments, optimize the quality and coverage of communication signals, and ensure the stability and efficiency of communication signals in flood control work.

[0023] Specifically, a flood prevention emergency communication device in this embodiment includes a base 1, a lifting assembly 2 and a rotating assembly 3, wherein the lifting assembly 2 is mounted on the upper surface of the base 1;

[0024] The lifting assembly 2 includes a fixed plate 21, which is arranged above the base 1. The base 1 and the fixed plate 21 are respectively provided with a reciprocating motor 22 and a bearing seat 23 on their opposite surfaces. A threaded screw 24 is rotatably connected between the reciprocating motor 22 and the bearing seat 23, and a sliding column 25 is meshed and slidably engaged on the threaded screw 24.

[0025] The rotating assembly 3 is mounted on the outer wall of the slide seat;

[0026] Among them, the rotating component 3 includes a sealed bearing 34, the inner wall of the inner ring of the sealed bearing 34 is connected to the outer wall of the upper end of the sliding column 25, and a mounting seat 35 is sleeved on the outer wall of the outer ring of the sealed bearing 34. The mounting seat 35 is rotatably connected to the sliding column 25 through the sealed bearing 34, and the antenna 11 is installed on the other end of the upper surface of the mounting seat 35.

[0027] During actual use, the user connects an external power supply to the reciprocating motor 22, so that the reciprocating motor 22 can drive the threaded screw 24 to rotate in both clockwise and counterclockwise directions, thereby allowing the slide column 25 to move up and down within the travel range of the threaded screw 24, so that the mounting base 35 can drive the antenna 11 to move up and down vertically within the travel range of the threaded screw 24, so that the position height of the antenna 11 can be adjusted, so that under the influence of different weather or obstacles, the height of the antenna 11 can be adjusted to reach the optimal position to obtain the best communication effect.

[0028] The output shaft of the reciprocating motor 22 is arranged vertically upward and the top end is connected to the bottom end of the threaded screw 24 . The outer wall of the upper end of the threaded screw 24 is connected to the inner wall of the inner ring of the bearing inside the bearing seat 23 .

[0029] The operation of the reciprocating motor 22 allows the output shaft of the reciprocating motor 22 to rotate clockwise and counterclockwise. With the cooperation of the bearing seat 23, the threaded screw 24 can rotate clockwise and counterclockwise between the reciprocating motor 22 and the bearing seat 23.

[0030] Two limiting rods 26 are installed between the opposite surfaces of the base 1 and the fixing plate 21 and are respectively located on both sides of the threaded screw 24 . The two limiting rods 26 both penetrate the sliding column 25 , and the sliding column 25 is slidably connected to the two limiting rods 26 .

[0031] By setting the limit rod 26, the connection between the fixed plate 21 and the base 1 is made more stable. Under the restriction of the limit rod 26, when the threaded screw 24 drives the sliding column 25 to reciprocate up and down, the sliding column 25 can make vertical reciprocating linear motion within the stroke range of the threaded screw 24, so that the movement of the sliding column 25 on the threaded screw 24 is smoother.

[0032] A support plate 31 is sleeved on the outer wall of the lower end of the sliding column 25 , a rotary motor 32 is mounted on one side of the upper surface of the support plate 31 , and a first gear 33 is sleeved on the outer wall of the output shaft of the rotary motor 32 .

[0033] The second gear 36 is sleeved on the outer wall of the mounting seat 35 . The first gear 33 and the second gear 36 are at the same level, and the first gear 33 and the second gear 36 rotate in coordination.

[0034] The rotating motor 32 is operated, and the output shaft of the rotating motor 32 drives the first gear 33 to rotate. With the cooperation of the sealed bearing 34, the second gear 36 drives the mounting base 35 to rotate, so that the antenna 11 can rotate in the horizontal direction, so that the antenna 11 can adjust the angle of receiving communication signals to adapt to different communication requirements, thereby ensuring the stability and reliability of the communication signal.

[0035] A controller 12 is mounted on one side of the outer wall of the reciprocating motor 22 , and a sensor 13 is mounted on the outer wall of the rotating motor 32 .

[0036] During actual use, the user inputs instructions to the controller 12, and the controller 12 transmits signals to the sensor 13 to control the operation of the rotating motor 32, so that when the antenna 11 adjusts its position to receive signals, the user can promptly control the operation of the reciprocating motor 22 and the rotating motor 32, so that the antenna 11 can be adjusted to the optimal position and fixed.

[0037] It should be noted that the controller 12 and the sensor 13 are respectively the input and output ends of the motor controller 12. The input end of the motor controller 12 receives instructions or signals, and then the processing unit inside the motor controller 12 processes the received control signals. The output end of the motor controller 12 outputs processed control signals, which directly drive the rotating motor 32 to operate. The output control signals may be voltage or current signals to achieve precise control of the rotating motor 32. The motor controller 12, the controller 12 and the sensor 13 are all existing mature devices.

[0038] The working principle of the above embodiment is:

[0039] In the first step, the user connects an external power supply to the reciprocating motor 22, so that the reciprocating motor 22 can drive the threaded screw 24 to rotate in both clockwise and counterclockwise directions, thereby allowing the slide column 25 to move up and down within the travel range of the threaded screw 24, so that the mounting seat 35 can drive the antenna 11 to move up and down vertically within the travel range of the threaded screw 24, so that the position height of the antenna 11 can be adjusted.

[0040] In the second step, while the user is operating the reciprocating motor 22, the user inputs instructions to the controller 12 to operate the rotating motor 32. The output shaft of the rotating motor 32 drives the first gear 33 to rotate, and with the cooperation of the sealed bearing 34, the second gear 36 drives the mounting base 35 to rotate, so that the antenna 11 can rotate in the horizontal direction, so that the antenna 11 can adjust the angle for receiving communication signals; under the dual drive of the reciprocating motor 22 and the rotating motor 32, the position height and the angle of receiving signals of the antenna 11 are adjusted at the same time to cope with different weather and environmental conditions. The position of the antenna 11 can be adjusted in time to ensure the stability and reliability of the communication signal.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
