Description

Technical Field

[0001] The utility model belongs to the technical field of solar energy power supply, and in particular relates to a power supply system based on agricultural irrigation. Background Art

[0002] At present, with the development of society and the transformation of smart agriculture, irrigation control systems are used for irrigation in the process of farmland management. Furthermore, due to the outdoor environment, it is not convenient to use city electricity, or the infrastructure cost of using city electricity is high, so solar panels are used for power supply, such as the published utility model patent: CN217905601U.

[0003] The irrigation system mainly uses electricity for valve actuators and some sensors, which have low power consumption and small power consumption, so the use of solar panels for power supply is in line with the concept of energy conservation and environmental protection. However, there are many valve actuators in the irrigation system. For example, there may be dozens or hundreds of valves and actuators for controlling valves on an irrigation pipeline. If solar panels are installed for each valve, the maintenance cost will increase, because even a small solar power supply system requires battery packs, inverters, control chips, voltage regulators and other electrical components. If one of them is damaged, the valve actuator will not work. Since each valve actuator is equipped with such a system, it will bring a lot of maintenance workload to the maintenance personnel after a long time of use. Utility Model Content

[0021] 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 only 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.

[0022] See also Figure 1-4 , the utility model provides a technical solution: a power supply system based on agricultural irrigation includes an irrigation pipe extending along the direction of the field ridge, a valve installed on the irrigation pipe and an actuator for controlling the valve switch;

[0023] It also includes a battery pack for powering the actuator, the battery pack is connected to the motor in the actuator through a line to realize power supply, a group of actuators are connected in parallel to one battery pack, and a group of actuators includes at least three actuators; the battery pack is used as an integrated end, and the battery pack and the actuator are connected only by wires. The battery pack itself integrates batteries for energy storage and a chip for controlling power supply (the chip can be selected as needed, such as PI C12F675, which is an 8-pin single-chip microcomputer with 6 I / 0 ports, built-in internal RC oscillator (oscillation frequency is 4MHz), 4-channel 10-bit A / D converter, and one comparator; this controller is widely used in battery control circuits, so the specific connection circuit is also relatively mature and will not be repeated here);

[0024] It also includes a movable solar charging vehicle for charging the battery packs. The solar charging vehicle is provided with a driving system and charges all the battery packs in a specific area by moving.

[0025] The structural diagram of the charging vehicle is shown in the figure below. Figure 1 and Figure 2As shown, the solar charging vehicle includes a base 1 and a leg 3. A solar panel 4 is provided on the end surface of the base 1, and a driving wheel set 2 is installed at the bottom of the leg 3. The driving wheel set 2 is part of the driving system. Since the driving system is not the focus of this embodiment and is also a mature existing technology, only a brief introduction is given. It is mainly composed of a controller and a driving wheel set 2. The driving wheel set is driven by a motor as a power output. The controller includes several distance measuring sensors ZH5430 installed on the legs. The distance measuring sensors are used to detect the distance between the driving wheel set 2 and the edge when the field ridge is traveling to prevent collision; then use the photoelectric encoder, electronic compass and gyroscope to control the path of the motor-driven wheel set 2; finally, use a single-chip microcomputer or remote control to perform the main control.

[0026] The leg 3 is a hollow structure, and a battery is installed inside. The base 1 is installed with an electrical system for connecting the electric energy converted by the solar panel to the battery. The PIC12F675 single-chip microcomputer can also be used inside the electrical system. The voltage of the solar panel is input through the interface, and then connected to the reverse charging diode and divided into three paths. One path is used to power the single-chip microcomputer, and the other path is used to charge the battery of the leg 3 through the fuse. The last path is output to an independent charging module. The charging module is provided with an interface for charging the external battery pack. In addition, the output end of the battery also leads to two paths, one for powering the driving wheel group, and one for leading to the charging module through a relay. Therefore, when charging the battery pack, both solar panels can be used for real-time charging and batteries in the charging car can be used for charging. The charging process control is controlled by the single-chip microcomputer through a program. The principle of this part is also a mature technology. Here, only a simple introduction to the principle is added. Since a ready-made electronic control system is used, no further elaboration is made.

[0027] Another important point of this embodiment is that since it is working outdoors and charging is done by remote control, the stability and safety of the connection during charging need to be considered. Figure 3 as well as Figure 4 As shown, the present embodiment has the following design: the charging module 5 is installed in the middle of the base 1, and the charging module 5 is configured as a liftable structure. When the solar charging vehicle moves to the top of the battery pack, the charging module 5 is lowered from the middle of the base 1 to charge the battery pack; a camera or an infrared sensor can be installed at the bottom of the base 1 to assist in alignment;

[0028] Reference Figure 2-Figure 3As shown, a docking module is provided at the bottom of the charging module 5 and the end of the battery pack. The structure of the docking module includes a charging column 51 provided on the charging module. A charging slot is provided in the middle of the charging column 51. A plug 53 is slidably connected in the charging slot. A first spring 52 is installed at the rear end of the plug 53. The upper force-bearing end of the first spring 52 is fixed to the top wall of the charging slot. When the first spring 52 is in a normal state, the lower end surface of the plug 53 is flush with the lower end surface of the charging column.

[0029] The docking module also includes a docking column 63 disposed on the battery pack, the outer edge of the docking column 63 is slidably connected to a protective cover 61, a second spring 62 is installed at the bottom of the protective cover 61, and the bottom force-bearing end of the second spring 62 is fixed on the internal table of the battery pack. When the second spring 62 is in a normal state, the upper end surface of the protective cover 61 is flush with the upper end surface of the docking column 63; Figure 4 As shown, a spring 631 is installed on the side wall of the docking column 63, and the spring 631 is connected to the battery inside the battery pack through a wire. A metal sheet corresponding to the position of the spring 631 is arranged on the surrounding side groove wall of the charging groove, and the metal sheet is used to contact the spring 631 to achieve electrical connection.

[0030] A pressure column is provided at the upper end of the protective cover 61. When the charging module moves downward, the pressure column is pressed downward, and the protective cover 61 slides downward, exposing the docking column 63. The cover continues to move downward, and the docking column 63 is inserted into the charging slot, and the plug 53 is pushed upward, so that the side wall of the docking column contacts the slot wall of the charging slot to achieve electrical connection.

[0031] Continuing to refer to the accompanying drawings, when not charging, the metal sheet in the charging slot is protected inside by the plug 53, and the spring sheet 631 of the docking post 63 is also surrounded inside by the protective cover 61; when charging, the docking post 63 enters the charging slot to complete charging, and is also in a closed environment, so that all electrical components in the non-charging state and the charging state can be better protected and adapt to the outdoor use environment.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
