DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Please see attached Figure 1-6 , in one embodiment of the present invention, wherein: Embodiment 1, see attached Figure 1 and 2 As shown, the electric heating drone hangar used on the pole tower is installed at the upper position of the pole tower 9, including a drone hangar 1 and a photovoltaic panel 8 installed on both sides of the bracket assembly 4 where the pole tower 9 is located. The drone hangar 1 is divided into an engine compartment located at the upper part and a control compartment 12 located at the lower part by a bottom plate 7. A drone 6 is parked in the engine compartment. A diagonal brace is connected to the lower part of the bracket assembly 4, and the diagonal brace is fixedly connected to the pole tower 9. The photovoltaic panel 8 generates electricity to provide power for the battery 2 set in the drone hangar 1. The battery 2 is installed in the control compartment 12 through a battery fixing frame 14. A controller 10 and a temperature sensor 11 are installed in the control compartment 12, and a heating component 3 is installed on the inner bottom surface of the control compartment 12; the bottom plate 7 is provided with regularly arranged heat dissipation holes 15.

[0019] For details, see the attached Figure 6 As shown, the photovoltaic panel 8 is electrically connected to the battery 2 through the controller 10, and the battery 2 is electrically connected to the heating component 3; the photovoltaic panel 8 charges the battery 2 through the controller 10, and when the battery 2 is fully charged, it can supply power to the heating component 3; an anti-reverse current electronic component is provided between the photovoltaic panel 8 and the controller, which is used for the photovoltaic panel 8 to supply power to the battery 2 in one direction; the controller 10 is electrically connected to the temperature sensor 11, and collects the temperature in the control compartment 12; a switch K2 is connected in series between the circuit of the battery 2 and the heating component 3; a switch K1 is connected in series between the circuit of the controller 10 and the heating component 3; the switch K1 and the switch K2 are opened and closed under the control of the controller.

[0020] The working principle of the electric heating drone hangar used on the above tower is as follows: The photovoltaic panel 8 receives sunlight to generate electricity to charge the battery 2; when the battery 2 is fully charged, the working mode is a floating charge state; When the drone hangar 1 is in a cold climate, the temperature sensor 11 in the control cabin 12 collects the temperature and sends it to the controller 10. The controller 10 controls the opening and closing states of the switches K1 and K2 according to the temperature threshold. The temperature threshold is divided into a low threshold and a high threshold. The operation is in the following two states: First, when the temperature in the control chamber 12 is at a low threshold, the switch K2 is closed, and the battery 2 supplies power to the heating component 3 until the temperature in the control chamber 12 is at a high threshold, and then the power supply is stopped; Second, in the above working condition, if the photovoltaic panel 8 is in the power generation state, the switch K1 is closed and the switch K2 is open, and the heating component 3 uses the power of the photovoltaic panel 8 until the temperature in the control chamber 12 reaches the high threshold value and then stops supplying power; The heating component 3 generates heat when it is powered, and the heat flows upward from the bottom of the control chamber 12, so the temperature in the control chamber 12 rises; at the same time, the heat flows from the heat dissipation holes 15 where the bottom plate 7 is located into the machine chamber, thereby increasing the temperature in the machine chamber.

[0021] The electric energy required by the heating component 3 gives priority to the electric energy provided by the photovoltaic panel 8, which can reduce the number of charge and discharge cycles of the battery 2 and help to increase the service life of the battery 2; the capacity of the battery 2 must not only meet the charging needs of the maximum number of drones in the warehouse, but also meet the electric energy required by the heating component 3 at night, and at the same time meet the maximum electric energy required for continuous rainy days in the location. The heat generated by the heating component 3 after receiving electricity not only increases the ambient temperature in the control compartment 12 where the battery 2 is located, but also increases the ambient temperature in the machine compartment where the drone 6 is located, thereby putting the electrical components of the electric heating drone hangar used on the tower in a good working environment.

[0022] Preferably, the lower threshold is -5°C and the upper threshold is 5°C.

[0023] Embodiment 2 is a preferred embodiment of the above embodiment, see attached Figure 4 and 5 As shown, the heating component 3 uses an electric heating tape 3-2, and an insulation layer 3-1 is installed on the bottom and side surfaces of the unmanned hangar 1; a strip groove for installing the electric heating tape 3-2 is opened on the insulation layer 3-1 located on the bottom surface, and the electric heating tape 3-2 is fixed by a protective film 3-3, and the two ends of the electric heating tape 3-2 serve as an incoming line 3-4 and an outgoing line 3-5, which are electrically connected to the battery 2 through a switch K1 and a switch K2; the bottom of the unmanned hangar 1 is detachably mounted on one side of the upper part of the bracket assembly 4 by a bolt assembly 5.

[0024] The electric heating drone hangar uses the principle of electric heating. In addition to the electric heating tape, the heating component 3 can also use an electric heating film. The electric heating tape is composed of a conductive polymer, two parallel metal wires and an insulating sheath. The resistivity of its heating element has a very high positive temperature coefficient "PTC" (Postive Temperature Coefficent), and they are connected in parallel with each other; it can automatically limit the temperature during heating and automatically adjust the output power with the temperature of the heated system. The electric heating film is made of conductive special ink, metal current-carrying strips, etc., which are processed and hot-pressed between insulating polyester films. Low-temperature electric heating film is selected.

[0025] Embodiment 3, specific, see attached Figure 1 and 3 As shown, in order to facilitate the installation and subsequent maintenance of the battery 2, a door hole for installing a control compartment door 17 is opened on one side of the control compartment 12, and a sealing ring 19 is opened on the near outer edge surface. When the control compartment door 17 is closed, the sealing ring 19 further improves the airtightness of the control compartment 12; when closed, the control compartment door 17 is fixed by a buckle 16 installed on the upper edge of the door hole, and a handle 18 is installed in the middle of the outer side surface; the lower part of the battery fixing frame 14 is connected to the upper part of the control compartment 12 through a slide rail 13.

[0026] After closing the control compartment door 17, the sealing ring 19 inside it fits the edge of the door hole, and the buckle 16 located on the upper edge of the door hole reliably clamps the control compartment door 17, wherein the sealing ring 19 is used to prevent dust; the control compartment door 17 is also installed with an insulation layer 3-1. During maintenance, pull up the buckle and open the control compartment door 17, pull the battery fixing frame 14 to slide out along the slide rail 13, and then the maintenance work can be carried out.

[0027] Embodiment 4, preferably, the diagonal brace is made of galvanized angle steel, one end of which is hinged to the lower part of the bracket assembly 4, and the other end of which is connected to the pole tower 9 through a clamp. The bracket assembly 4 is a structure in which a galvanized steel plate is fixed on a galvanized angle steel frame. Parts made of galvanized material have good corrosion resistance.

[0028] The above-mentioned galvanized parts can be formed by light aluminum alloy or plastic processing, and have the advantage of lightness.

[0029] The storage battery 2 adopts a soft-pack lithium battery pack, which has both high capacity characteristics and lightness. The soft-pack lithium battery pack realizes power management through a BMS circuit board.

[0030] The thermal insulation layer 3-1 uses thermal insulation pearl cotton aluminum film. The thermal insulation pearl cotton aluminum film is composed of pearl cotton and aluminum film. Pearl cotton is a material with an independent bubble structure. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene grease. These bubbles can effectively prevent the transfer of heat; the aluminum film has good reflective properties and can reflect heat back, thereby reducing heat absorption. The combination of the two greatly improves the thermal insulation effect of the material.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
