Referring to fig. 4 and 5, in particular, the mounting assembly 8 includes a mounting bolt 81 and a mounting nut 82. The first mounting part 51 and the second mounting part 61 are both provided with mounting adjusting holes 511 for the mounting bolts 81 to penetrate through, and the mounting adjusting holes 511 are distributed in a long strip shape; the width of the mounting adjustment hole 511 is larger than the outer diameter of the screw portion of the mounting bolt 81 and smaller than the outer diameter of the screw portion of the mounting bolt 81. The mounting bolts 81 are inserted into the first mounting portion 51 and the second mounting portion 61 and are screwed with the mounting nuts 82, so that the first mounting portion 51 and the second mounting portion 61 can be fixedly clamped on both sides of the angle steel.
Referring to fig. 5, in the present embodiment, since one side of the angle iron is fixed to the first fixing portion 52 or the second fixing portion 62, it is difficult to completely align the first and second mounting portions 51 and 61; the installation adjusting hole 511 is long, so that when the first installation part 51 and the second installation part 61 are not completely aligned, the installation bolt 81 can still penetrate through the first installation part 51 and the second installation part 61, and the installation is convenient for an operator to install.
Referring to fig. 4 and 5, further, the mounting nut 82 includes a pre-mounting nut 821 and a close-fitting nut 822, and in this embodiment, at least one pre-mounting nut 821 and at least one close-fitting nut 822 are disposed between each set of the first mounting portion 51 and the second mounting portion 61.

By using the installation method, an operator can fix the pre-installation nut 821 and the installation bolt 81 in advance, and the step of aligning the pre-installation nut 821 and the installation bolt 81 and then connecting the pre-installation nut 821 and the installation bolt 81 through threads after the installation bolt 81 passes through the first installation part 51 and the second installation part 61 is omitted, so that the installation method is more convenient. After the preassembling nut 821 is installed by an operator, the support 4 and the angle steel are preliminarily preassembled and fixed, the support of the operator for the support 4 is shared, the operator can conveniently perform the next step of installation, and the operation efficiency is improved.
Referring to fig. 4 and 5, the minimum width of the interference nut 822 is greater than the width of the installation adjustment hole 511. After the pre-installed nut 821 is installed, an operator can use another installation bolt 81 to place the tight-fitting nut 822 on one side of the pre-installed nut 821; then, the mounting bolt 81 is inserted into the first mounting portion 51 and the second mounting portion 61 and is in threaded connection with the tight-fitting nut 822, so that the tight-fitting nut 822 and the mounting bolt 81 abut against the first mounting portion 51 and the second mounting portion 61, and the first mounting portion 51 and the second mounting portion 61 clamp the angle steel. On the other hand, the tight-fitting nut 822 occupies the rotation space of the pre-installed nut 821, and can prevent the pre-installed nut 821 from rotating by itself, thereby reducing the risk that the pre-installed nut 821 is separated from the installation adjusting hole 511 by itself due to shaking, and reducing the maintenance cost.

The effective inclination refers to an inclination that the radar detector 2 needs to achieve when the lowest detection position is located within the detection area of the radar detector 2, i.e., an inclination that the radar detector 2 satisfies the detection requirement.
S3, detection range adjustment: the inclination angle of the radar detector 2 is adjusted based on the difference between the effective inclination and the installation inclination.
After the manager knows the effective inclination and the installation inclination, the radar detector 2 can be remotely controlled to rotate, so that the radar detector 2 can reach the inclination meeting the detection requirement.
In addition, in order to facilitate the manager to calculate the installation inclination later, when the operator installs the control box 1, the operator may adjust the inclination of the control box 1 through the adjusting bolt 412, so that the inclination of the radar detector 2 is adjusted to 0 °, even if the installation inclination is 0 °. When the remote control radar detector 2 rotates, a manager can directly adjust the inclination of the radar detector 2 to an effective inclination.
Referring to fig. 7, taking a plain area as an example, the distance between two adjacent towers is 300m, the tower height is 30m, and if the detection area of the radar detector 2 is 200m, one radar detector 2 needs to be installed at the middle part of each tower arm of the two towers to ensure an effective warning area range.
