In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0055] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0056] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0057] As shown in Figures 1 to 16 A portable radar monitoring system with adjustable pitch angle is proposed, which comprises a tripod 41; a support plate 40 is arranged on the tripod 41; a pitch angle rotating shaft base is arranged on the support plate 40, and the pitch angle rotating shaft base has a reserved through hole one 23; a radar shell extension piece 20 is rotatably arranged on the pitch angle rotating shaft base, and the radar shell extension piece 20 has a reserved through hole two 28, the reserved through hole two 28 and the reserved through hole one 23 are communicated, and are configured to be locked by using fasteners.

[0058] In the embodiment, in order to solve the problem that the pitch angle of the portable radar monitoring system is not convenient to adjust in the related art, the radar shell extension piece 20 is rotatably arranged on the pitch angle rotating shaft base, and the radar shell extension piece 20 and the pitch angle rotating shaft 50 base 21 are connected through the reserved through hole one 23 and the reserved through hole two 28 of each other, and the rotation damping is provided by using fasteners such as bolts. When the pitch angle needs to be adjusted, the fastener locking is released, the radar shell extension piece 20 is rotated to a specified angle, and then the fastener locking is tightened, so that the adjustment of the pitch angle of the portable radar monitoring system is realized simply and conveniently.

[0059] Specifically, the tripod 41 provides a stable support base for the entire system, ensuring that the system can be placed stably in various outdoor environments and will not easily sway due to uneven ground or wind and the like. The support plate 40 serves as a mounting platform for subsequent components, ensuring the overall integrity and stability of the structure.

[0060] Further, the rotation shaft 50 is arranged on the radar shell extension 20 at one side of the reserved through hole 23, and the radar shell extension 20 is arranged on the rotation and pitch angle shaft base through the rotation shaft 50; the rotation shaft 50 has an extended end 52 extending to the outside of the rotation and pitch angle shaft base, and the limiting piece 51 is arranged on the extended end 52 and has a limiting groove 53; the locking piece 54 is arranged to swing or move relative to the pitch angle shaft base 21, and the locking piece 54 has a limiting tooth 55 configured to be clamped in the limiting groove 53 after swinging or moving with the locking piece 54.

[0061] In this embodiment, a convenient locking or unlocking method of the radar shell extension 20 is provided, specifically, a fastener is no longer used, the rotation shaft 50 is made of stainless steel, one end of the rotation shaft 50 penetrates through the radar shell extension 20 and smoothly rotates through a bearing, and the other end of the rotation shaft 50 extends out of the pitch angle shaft base. The limiting piece 51 is a metal block fixed on the extended end 52 of the rotation shaft 50 by welding or threaded connection, the shape of the limiting groove 53 is not limited and is the same as the profile of the limiting tooth 55, and the limiting tooth 55 is uniformly distributed on one side edge of the locking piece 54. When the pitch angle needs to be adjusted, the rotation shaft 50 is rotated to make the limiting groove 53 rotate to a suitable position, and then the locking piece 54 is swung or moved to make the limiting tooth 55 of the locking piece 54 clamped in the limiting groove 53 to limit the rotation of the rotation shaft 50, thereby fixing the pitch angle.

[0062] Further, the rotation axis direction of the radar shell extension 20 is defined as the x direction, and the bracket 56 is arranged on the rotation and pitch angle shaft base; the eccentric wheel 57 is arranged to rotate on the bracket 56, the rotation axis direction of the eccentric wheel 57 is the y direction, the eccentric wheel 57 abuts against the locking piece 54, and the eccentric wheel 57 rotates to swing or move the locking piece 54. Further, the wrench 58 is arranged on the eccentric wheel 57.

[0063] In this embodiment, a convenient driving method of the locking piece 54 is provided, the wrench 58 is used to rotate the eccentric wheel 57, the eccentric structure of the eccentric wheel 57 is used to convert the rotation movement into the swinging or moving movement of the locking piece 54, and then the state of the limiting piece 51 is controlled, so that the operator can quickly and conveniently adjust the locking or unlocking, and the operation efficiency is improved.

[0064] The wrench 58 is designed to be foldable, and one end is connected to the shaft of the eccentric wheel 57 by keying or welding. When the pitch angle needs to be adjusted, the eccentric wheel 57 is rotated by operating the wrench 58, and the rotation of the eccentric wheel 57 pushes the locking piece 54 to swing or move, thereby achieving the unlocking or locking operation of the limiting piece 51.

[0065] Further, the locking piece 54 is arranged to swing relative to the pitch axis base 21 or the bracket 56, and the limiting teeth 55 are configured to be clamped in the limiting groove 53 after the locking piece 54 swings.

[0066] As shown in Figure 4 and Figure 5 In this embodiment, as one of the embodiments of the locking piece 54, it is designed to swing, which can be a plastic plate or a metal plate with a certain elasticity. After the eccentric wheel 57 rotates, the locking piece 54 can swing to clamp the limiting groove 53, or the locking piece 54 can rebound to cancel the clamping of the limiting groove 53.

[0067] Further, the locking piece 54 is arranged to move relative to the bracket 56, and the limiting teeth 55 are configured to be clamped in the limiting groove 53 after the locking piece 54 moves. The handle 60 is also provided, which has an inner pressing groove 61 and an outer pressing groove 62, and also has a limiting cross beam 63. The bracket 56 has a limiting through groove 64, and the limiting cross beam 63 moves in the limiting through groove 64. The locking piece 54 is arranged on the handle 60 and moves with it.

[0068] As shown in Figure 6 In this embodiment, as another embodiment of the locking piece 54, the locking piece 54 is designed to move. At this time, the eccentric wheel 57 can still rotate to push the locking piece 54 to move and clamp the limiting groove 53, but the locking piece 54 no longer relies on its own elasticity to reset. After the eccentric wheel 57 rotates to remove the pushing of the locking piece 54, the locking piece 54 on the handle 60 is reset and separated from the limiting groove 53 by manually pulling the handle 60. The handle 60 is designed with an inner pressing groove 61 and an outer pressing groove 62 that are comfortable to hold, facilitating the operation of the handle 60.

[0069] The limiting cross beam 63 and the limiting through groove 64 cooperate to limit the handle 60.

[0070] Further, the pitch axis base has a scale pointer notch 24, and the radar shell extension 20 has a scale notch 25. The scale pointer notch 24 is aligned with the scale notch 25.

[0071] In this embodiment, the scale pointer notch 24 is located at the edge of the pitch axis base and is a rectangular notch with pointer marks inside. The scale notch 25 is a long strip-shaped notch of transparent plastic material on the radar shell extension 20 corresponding thereto, and has angle scales engraved inside.

[0072] In the installation, ensure that the two slots are accurately aligned, when the radar shell extension 20 rotates, the current pitch angle can be read by observing the position of the pointer on the scale. The pitch angle of the radar can be intuitively displayed, which facilitates the operator to accurately position and record the angle when adjusting the angle, and improves the accuracy and traceability of the monitoring data.

[0073] Further, it also includes a radar box body 11, which is arranged on the radar shell extension 20; the upper cover 10 is arranged on the radar box body 11. Further, the radar box body 11 has a circuit board mounting hole 12, and the radar circuit board 14 is arranged on the circuit board mounting hole 12. The lithium battery 15 is arranged in the radar box body 11 through the fixing member 13.

[0074] In this embodiment, the radar box body 11 is a box body made of polycarbonate material with good wave permeability. The position and size of the circuit board mounting hole 12 are designed according to the shape of the radar circuit board 14 and the position of the external network port and USB port. The radar circuit board 14 is fixed on the mounting hole by screws. The upper cover 10 is sealed and connected with the radar box body 11 by a sealing rubber ring to prevent dust and moisture from entering. The fixing member 13 is a plastic buckle. The lithium battery 15 and the concentrator 16 are fixed in the radar box body 11 by the fixing member 13. The electrodes of the lithium battery 15 and the concentrator 16 are connected with the radar circuit board 14 through wires.

[0075] The radar box body 11 provides physical protection for the radar circuit board 14 and the lithium battery 15, preventing them from being impacted by external forces, electromagnetic interference, and harsh environments. The upper cover 10 reduces the risk of short circuit caused by the exposed circuit board contacting conductors, prolonging the service life of internal electronic components. The radar circuit board 14 realizes signal processing and transmission functions of the radar. The lithium battery 15 provides stable power supply for the entire system, enabling the system to work normally without external power supply. The concentrator 16 integrates the communication network port and data USB port of the radar circuit board into one cable. This reduces external wiring connections and makes it easier for users to use.

[0076] The flat plate support is composed of a flat plate shell 30 and two flat plate shell support members 31 on the left and right, located at the rear end of the system. The flat plate shell 30 is provided with a flat plate limiting guide rail 32 on both sides of the middle, which is designed to allow the protruding part behind the flat plate to tightly fit the flat plate limiting guide rail 32, achieving stable placement of the flat plate. The flat plate shell 30 is provided with a flat plate support side window 33 on both sides, which is designed to expose the USB and charging holes on both sides of the flat plate, facilitating wiring connection.

[0077] The outer hexagonal screw limiting hole 26 is used to accommodate screws and other fasteners. At the same time, the thickened side wall 27 around the bolt hole is provided on both sides of the radar shell extension 20, which fills the assembly gap between the radar shell extension 20 and the shaft base 21.
