DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are 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.
[0025] This application provides a directional antenna with adjustable direction, see Figure 1 , Figure 1 The schematic diagram is a schematic diagram of the overall structure of a directional antenna with adjustable direction according to a preferred embodiment of the utility model. The directional antenna with adjustable direction comprises: a directional antenna group 101, a mounting rod 102 for mounting the directional antenna group 101, and a base 103 movably connected to the mounting rod 102.
[0026] In the preferred embodiment of the present application, the directional antenna group 101 is arranged on the top of the mounting pole 102. Of course, the installation position of the directional antenna group 101 on the mounting pole 102 can be set at other positions of the mounting pole according to actual needs.
[0027] In the present application, the directional antenna group 101 includes: four transverse directional antenna heads 101-1 and a vertical directional antenna head 101-2. The four transverse directional antenna heads 101-1 are arranged on the same plane, and the four transverse directional antenna heads 101-1 are arranged vertically in pairs. The vertical directional antenna head 101-2 is arranged perpendicular to the plane and upward. The four transverse directional antenna heads 101-1 and the vertical directional antenna heads 101-2 are distributed in the same circumscribed sphere. It should be noted that the positional relationship between the four transverse directional antenna heads 101-1 and the vertical directional antenna heads 101-2 is set to be distributed in the same circumscribed sphere because such a setting can make the directional antenna have a stronger signal gain effect in the direction of gain.
[0028] In the present application, the distance between the four transverse directional antenna heads 101-1 is greater than 100 times the ultrasonic wavelength. In the preferred embodiment of the present application, the ultrasonic wavelength is 0.17 mm. The reason why the distance between the four transverse directional antenna heads 101-1 is set to be greater than 100 times the ultrasonic wavelength is mainly to avoid ultrasonic interference. Because other equipment often performs ultrasonic detection during the detection process, in order to avoid ultrasonic waves causing the antenna heads to resonate, the distance between the four transverse directional antenna heads 101-1 is set to be greater than 100 times the ultrasonic wavelength.
[0029] In the present application, the bottom of the mounting rod 102 is provided with two protrusions 102-1, see Figure 2 , Figure 2 It is a schematic diagram of the structure of the protrusion at the bottom of the mounting rod in the directional antenna with adjustable direction in a preferred embodiment of the utility model. The protrusion 102-1 is symmetrically arranged at both ends of the bottom of the mounting rod 102. The protrusion 102-1 can be in the form of a marble.
[0030] In the present application, the base 103 is provided with a plurality of recesses 103-1 matching the protrusion 102-1, see Figure 3 , Figure 3 103 - 1 is a schematic diagram of the structure of the recesses on the base of the directional antenna with adjustable direction in a preferred embodiment of the utility model. The number of the recesses 103 - 1 is 16, which are symmetrically and evenly arranged around the base 103 .
[0031] In a specific implementation, by rotating the mounting rod 102, the protrusion 102-1 is positioned and matched with the recesses 103-1 in different directions to adjust the direction of the directional antenna.
[0032] It should be noted that the four horizontal directional antenna heads 101-1 can only correspond to four directions. When the direction of the directional antenna needs to be changed, the direction corresponding to the directional antenna can be adjusted by rotating the mounting rod 102. The rotation is specifically achieved through the two protrusions 102-1. Specifically, there are 16 recesses 103-1 on the base 103, and the 16 recesses 103-1 are marked as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16 in sequence, wherein 1 and 9 are arranged relatively, 2 and 10 are arranged relatively, 3 and 11 are arranged relatively, 4 and 12 are arranged relatively, 5 and 13 are arranged relatively, 6 and 14 are arranged relatively, 7 and 15 are arranged relatively, and 8 and 16 are arranged relatively. For example, when the two protrusions 102-1 match 1 and 9, the directional antenna points to due south and due north; when the two protrusions 102-1 match 5 and 13, the directional antenna points to due east and due west; when the two protrusions 102-1 match 3 and 11, the directional antenna points to the northeast (45 degrees north of east) and the southwest (45 degrees south of west); when the two protrusions 102-1 match 7 and 15, the directional antenna points to the northwest (45 degrees north of west) and the southeast (45 degrees south of east); when the two protrusions 102-1 match 2 and 10, the directional antenna points to 22.5 degrees north of east and 22.5 degrees south of west. When the two protrusions 102-1 match 4 and 10, the directional antenna points to 67.5 degrees north by east and 67.5 degrees south by west. When the two protrusions 102-1 match 6 and 14, the directional antenna points to 67.5 degrees south by east and 67.5 degrees north by west. When the two protrusions 102-1 match 8 and 16, the directional antenna points to 22.5 degrees south by east and 22.5 degrees north by west. There are a total of sixteen directions.
[0033] In the present application, when the protrusion 102-1 rotates, the corresponding recess 103-1 on the base can be positioned, thereby adjusting the directional antenna to a very suitable position, thereby increasing the directions in which the directional antenna can be directed.
[0034] In the present application, the shapes of the protrusion 102-1 and the depression 103-1 are not specifically limited. The protrusion 102-1 can be set to a variety of shapes such as circular, positive direction, triangle, hexagon, etc. Correspondingly, the shape of the depression 103-1 needs to be set to a shape that matches the protrusion 102-1, so that the protrusion 102-1 and the depression 103-1 fit better.
[0035] The present utility model also provides a signal gain device for a power distribution terminal, see Figure 4 , Figure 4 It is a structural schematic diagram of a signal gain device for a power distribution terminal according to a preferred embodiment of the utility model, wherein the signal gain device for a power distribution terminal comprises: a power module 200, a directional antenna 100 with adjustable direction, and a signal gain module 300; the power module 200 is connected to the signal gain module 300, and the power module 200 is used to provide power for the signal gain device 300; the directional antenna 100 with adjustable direction is connected to the signal gain module 300, and the signal gain module 300 is used to receive the signal of the directional antenna 100 with adjustable direction in a specified direction.
[0036] Specifically, the preferred schemes of each module in the signal gain device for the power distribution terminal can be found in Figure 5 , the power module is used to provide working power for the device. In the present application, the power module can be a 300W photovoltaic power generation module, specifically a 300W single crystal panel, with solar energy as the main power generation energy source, and can provide working power for the device continuously for 24 hours through photovoltaic panels, power management modules, and power circuits. The antenna module can be the above-mentioned directional antenna, which radiates in a certain angle range in the horizontal direction, which is directional radiation, and the smaller the lobe width, the greater the gain. Because the directional antenna is directional, the signal strength in this direction is stronger and propagates farther. The signal gain module is used to receive the signal of the directional antenna with adjustable direction in the specified direction, and gain the signal of the directional antenna in the specified direction. The signal gain module can be a high-power signal gain module, such as a high-power signal amplifier, and the signal gain strength of the high-power signal gain module is stronger, and the signal transmission distance is also farther. Specifically, the high-power signal gain module has a signal gain strength of more than -35dBm, and can extend the signal transmission by 1000-3000 meters. The device box module can use an ABS box. Since the box needs to be placed outdoors, the box needs to be heat-resistant and corrosion-resistant, and the hardness needs to be greater than 90, and the material density needs to be less than 2.0g / cm3. Therefore, in this application, an ABS box can be used. The hardness of ABS material is about 93, the density is about 1.05g / cm3, and it is suitable for outdoor high-temperature placement.
[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
