Description

Technical Field

[0001] The invention belongs to the technical field of broadband radar signal detection, and in particular relates to a broadband radar traveling device capable of adjusting and suppressing detection signal clutter. Background Art

[0002] With the rapid development of science and technology, people are gradually entering the Internet age, and broadband is one of the most indispensable components in the network field. Among them, broadband radar is widely used as a network broadband signal transmitter; the so-called broadband radar is a radar whose fractional bandwidth (FBW) of the transmitted signal is greater than 0.25. It can generally perform a series of processing and processing on very short single pulse signals, including signal generation, transmission, reception and processing, and can realize functions such as communication, detection and remote sensing.

[0003] In order to monitor the radar signal, a detection traveling device is required; some existing detection traveling devices are not provided with an adjustable shock-absorbing structure, and cannot be applied to various complex detection environments. During the movement of the device, different degrees of shock-absorbing effects cannot be achieved according to changes in the working environment, resulting in the device being shaken due to changes in the working environment when in use, causing static clutter to change into dynamic clutter, which increases the difficulty of detecting the target signal; at the same time, a good sound insulation structure is not provided in the device, and noise reduction in the device is generally achieved through sound-absorbing pads. However, the noise reduction effect of the device as a whole cannot be optimal if it only relies on the sound-absorbing effect of the sound-absorbing pads, and certain improvements are needed; and the device will generate high heat during operation. If the device is not dissipated and cooled in time, irreversible damage may be caused to the radar and the device; therefore, there is an urgent need for a device that can simultaneously achieve heat dissipation, shock absorption and noise reduction of a broadband radar traveling device to increase the service life of the broadband radar and improve work efficiency.

At the same time, the thrust of the piston head 41 can promote the flow of coolant in the coolant pipe, thereby improving the cooling efficiency (if combined with the circulation of the coolant itself, the cooling efficiency is greatly improved compared with the ordinary circulation cooling alone); the other ends of the two coolant pipes 9 are respectively connected to the two coolant injection ports 3 opened at the rear of the shell 1.

[0032] As a more preferred embodiment, each group of coolant pipes 9 and shock absorbing components 4 are separated into a space by the outer shell 1 and an inner partition 7 .

[0034] As a more preferred embodiment, Figure 2 As shown, the coolant pipe 9 is a continuous S-shaped pipe, which can carry more coolant to improve the cooling effect.

[0035] As a more preferred embodiment, two coolant outlets are opened on the side wall of the shell 1, and the outlets opened on the sides of the two coolant pipes 9 are respectively connected to the two coolant outlets; the coolant reserve tank is fixed on the top of the shell 1; the coolant injection port 3 and the coolant outlet are respectively connected to the liquid outlet of the coolant reserve tank and the liquid inlet of the coolant reserve tank; the liquid outlet of the coolant reserve tank is connected to the liquid inlet of the liquid pump, and the liquid outlet of the liquid pump is connected to both coolant injection ports 3; the liquid pump is electrically connected to the controller and controlled by the controller.

[0036] As a preferred embodiment, Figure 3 As shown, a limiting member is provided at one end of the screw rod 11 close to the noise reduction assembly 10 to limit the fan assembly.

[0037] As a preferred embodiment, the four traveling wheels 5 are respectively fixedly connected to the output shafts of four steering gears fixed to the bottom of the housing 1, and the four steering gears are all electrically connected to the controller and controlled by the controller.

[0038] When all the above embodiments are present, the working principle of the present invention is:

[0039] Four steering gears installed at the bottom of the housing 1 drive the four traveling wheels to move; during the movement, the motor 13 is started, driving the lead screw 14 to rotate, so that the fan assembly 12 moves forward; the threaded sleeve 121 in the fan assembly 12 moves forward in a spiral motion along the screw 11, so that the fan blades 123 fixed on the threaded sleeve 121 rotate, and the rotating fan blades 123 blow the hot air inside the housing 1, so that the hot air is discharged to the outside of the device through the ventilation net 6 and the heat dissipation net 2; when the fan assembly 12 moves to the front end of the screw 11, the limiter will limit the movement of the fan assembly 12; at this time, the two push rods 122 on the fan assembly 12 will abut against the noise reduction group The two reflective plates 101 of the component 10 are rotated forward and backward, so that the two reflective plates 101 are deflected around the optical axis 104 and the torsion spring 103 is tensioned; then, the motor 13 is reversed, driving the fan component 12 to move in the opposite direction, and the fan blades 123 rotate in the opposite direction to perform secondary heat dissipation; at the same time, the two push rods 122 on the fan component 12 are away from the two reflective plates 101, and under the action of the torsion spring 103, the two reflective plates 101 return to the initial state; as the motor 13 repeatedly rotates forward and reverse, the fan component 12 can achieve continuous heat dissipation, and the noise reduction component 10 is reciprocated and deflected under the action of the push rod 122, so as to scatter the noise in the housing and avoid noise concentration;

[0040] More preferably, during the movement, the pump injects coolant into the coolant pipe 9; when the shell vibrates, the shock absorbing plate 46 will come into contact with the ground, giving the spring 44 an upward thrust. Under the action of the spring 44, the impact force will be buffered once, and at the same time, the slider 43 will slide upward along the slide groove, pushing the piston rod 42 and the piston head 41 to move upward. Under the action of the liquid resistance of the coolant, the impact force of the piston head 41 is buffered for a second time, and after the external force of the ground on the shock absorbing plate 46 disappears, the coolant causes the piston head 41 and the piston rod 42 to move downward; there is an interaction force between the piston head 41 and the coolant, and the thrust of the piston head 41 on the coolant can promote the flow of coolant in the coolant pipe, thereby improving the cooling efficiency.
