Description

TECHNICAL FIELD

[0001] The application relates to the technical field of outdoor energy storage devices, in particular to an outdoor energy storage device for a photovoltaic power station. BACKGROUND

[0002] The outdoor energy storage device for a photovoltaic power station is a portable device integrating solar power generation and energy storage functions, which can convert light energy into electrical energy through a solar panel and store the electrical energy in a battery to meet outdoor power needs. It combines mobile charging and solar energy charging, is particularly suitable for scenes without fixed power supply such as camping, hiking and field work, and can combine portable energy storage and renewable energy to enable users to obtain stable power even when disconnected from the power grid. It is not only a convenient tool for outdoor life but also an energy guarantee for emergency scenes.

[0003] For example, CN117080608A discloses an outdoor energy storage device suitable for low-temperature environments, which comprises a shell, a battery and an inverter arranged in the shell. The shell is provided with an inner cavity, and the inner cavity is divided into a battery compartment and an inverter compartment by a heat insulation layer. The bottom opening of the inner cavity is closed by a heat-conducting base. The inverter is installed in the inverter compartment and is in contact with the base through a heat dissipation member. The battery compartment contains a battery, and the space between the batteries, the space between the battery and the shell, and the space between the battery and the base are filled with phase change heat dissipation material. The base is in contact with the phase change heat dissipation material to achieve heat conduction. This structure ensures that the outdoor energy storage device can be used in low-temperature environments, solving the problem of user discomfort in outdoor use at high altitudes, overnight in high-altitude snow-capped mountains and in low-temperature environments.

[0004] 1. In the actual use process of the outdoor energy storage device, because the outdoor temperature changes, especially in summer, the outdoor environment temperature can reach above 40 DEG C, which makes the internal battery and power conversion module of the outdoor power supply generate a large amount of heat during continuous high-power discharge or long-time solar charging. If heat dissipation is not timely, the internal temperature can exceed 60 DEG C. In the prior art, the overload protection function of most outdoor power supplies is mainly designed for common electrical faults such as overvoltage, overcurrent and short circuit, and lacks an effective response mechanism for overload risk in high-temperature environments. When the temperature inside the device is too high, the chemical activity of the energy storage battery is abnormal, which can easily cause thermal runaway. The performance of the power conversion element also decreases significantly, leading to circuit parameter deviation and even device burning. Once high-temperature overload occurs, not only the service life of the outdoor power supply will be significantly shortened, but also safety accidents such as battery bulging and fire may occur, which seriously threatens the personal and property safety of users. In addition, the traditional heat dissipation method mainly relies on air cooling design, which has limited effect in extremely high-temperature environments and cannot quickly reduce the internal temperature of the device, making it difficult to fundamentally avoid the problem of high-temperature overload.

[0005] 2. Due to the environment outdoors often accompanied by some changes, especially equipment in outdoor operation in rainy days, may cause the device exposed to rain, even if the current device has a certain waterproof ability, but in practical application is still difficult to withstand long rain, rainstorm scouring or accidental immersion. Rainwater penetrates into the power supply, will cause short circuit, corrosion of components, and then cause equipment failure. Thus rain and metal circuit on the circuit board contact, will damage the insulation layer, cause short circuit between lines, so that the power supply can not work normally; battery interface, charging interface and other parts if rainwater intrusion, will accelerate the oxidation of metal contacts, shorten the battery life, and may even cause serious safety accidents such as electric shock, fire.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original photovoltaic power station outdoor energy storage device. SUMMARY

[0007] The technical scheme of the present application provides a significantly different solution from the prior art, and specifically aims to provide a photovoltaic power station outdoor energy storage device to solve the problem of easy damage of the device in high outdoor temperature and rainy days.

[0008] To achieve the above object, the present application provides the following technical scheme: a photovoltaic power station outdoor energy storage device, comprising an outdoor power supply, an overload protection mechanism arranged on one side of the inner wall of the outdoor power supply for providing protection function for the device when the temperature inside the device is too high, and a rainwater triggering mechanism arranged on the top of the overload protection mechanism for automatically triggering the overload protection mechanism to provide protection for the device when it rains.

[0009] The overload protection mechanism comprises an outer shell body mounted on the top of the inner wall of the outdoor power supply, an inner shell body arranged on the inner wall of the outer shell body, a limiting clamp rod mounted on the top of the inner shell body, a connecting block arranged on one end of the limiting clamp rod, and a trigger ball movably arranged on the inner wall of the connecting block.

[0010] The rainwater triggering mechanism comprises a pressing block movably mounted on the top of the trigger ball, an offset link movably mounted on the outer wall of the pressing block, an active link connected to one end of the offset link, and a connecting sliding groove arranged on the outer wall of the active link.

[0011] Preferably, the outer wall of the trigger ball is connected with a reset rod, the bottom of the inner wall of the outer shell body is provided with a press switch, the bottom of the press switch is provided with a storage battery, one side of the outer shell body is provided with a heat dissipation opening, and the outside of the heat dissipation opening is connected with an air outlet pipe.

[0012] Preferably, one end of the pressing block is connected with a telescopic rod, the outer wall of the telescopic rod is provided with springs, one end of the telescopic rod is connected with a receiving bin, the top of the receiving bin is provided with a water pipe, one end of the water pipe is provided with a water collecting disc, one side of the outer wall of the receiving bin is provided with a drain pipe, and the outer wall of the water pipe is provided with a connecting telescopic rod.

[0013] When the internal battery pack temperature of the energy storage device is greater than or equal to 55 DEG C, it is considered that the temperature is too high, and when the temperature is greater than or equal to 65 DEG C, it is a dangerous critical value, which may cause the battery to heat runaway, smoke and fire, and power must be cut off immediately.

[0014] Preferably, the limiting clamp rods are movably connected through shafts, and the limiting clamp rods are made of metal material.

[0015] The limiting clamp rod made of copper will expand due to high temperature, so that the inner diameter of the limiting clamp rod becomes larger. The inner diameter of the limiting clamp rod becomes larger because the copper ring is a structure stacked by countless concentric circular sheets. When heated, each sheet will expand due to the increase of atomic spacing. Each layer of sheet grows outward, like the annual rings of a tree, which will become wider every year. For the inner circle of the copper ring, it will also expand outward due to the expansion of atoms. Therefore, the inner diameter of the entire copper ring becomes larger, that is, the copper ring expands as a whole, not just the outer circle becomes larger. Therefore, the inner diameter also becomes larger, not smaller.

[0016] Preferably, the connecting blocks have a cuboid three-dimensional view, and the connecting blocks are made of elastic material.

[0017] The connecting block is made of silicone rubber, which has excellent high and low temperature resistance. The working temperature range can reach -60 DEG C to 250 DEG C. In a high temperature environment, the connecting block can still maintain good elasticity and flexibility, so that the connecting block has the functions of deformation and resetting.

[0018] Preferably, the outer wall of the movable connecting rod is connected with the outer wall of the limiting clamp rod, and the movable connecting rod is matched with the connecting sliding groove.

[0019] Preferably, one end of the offset connecting rod is movably connected with the outer wall of the pressing block, and the other end of the offset connecting rod is movably connected with one end of the movable connecting rod.

[0020] Preferably, the outer wall of the outer shell and the inner shell is provided with a sliding groove, and the diameter of the sliding grooves of the outer shell and the inner shell is matched with the diameter of the reset rod.

[0021] The pressing switch is aligned with the bottom of the trigger ball, and the pressing switch and the storage battery are electrically connected through electrical signals.

[0022] The two sides of the receiving bin are provided with sliders and sliding grooves matched with each other, and the bottom of the outer wall of the receiving bin is connected with one end of the telescopic rod.

[0023] Compared with the prior art, the present application has the following advantages:

[0024] 1. The overload protection mechanism of the present application can prevent the device from being damaged due to overheating of the internal temperature when the device is running outdoors. When the internal temperature of the device is too high, the limit clamp rod expands due to heat, causing the inner diameter to expand, triggering the ball to disengage and press the switch to cut off the battery power supply. After the temperature decreases, the reset lever pulls the trigger ball back to its original position, and the device can be restarted. This avoids the risk of damage or even explosion due to overheating of the device, thereby improving the safety performance of the device and better adapting to changes in the external environment temperature, further improving the service life of the device, and improving the stability and versatility of the device, and reducing the safety hazards for the user and nearby people.

[0025] 2. The overload protection mechanism and the rainwater triggering mechanism of the present application can automatically cut off the power supply when it rains, thereby preventing the device from being damaged. Water entering the device during rainy days may cause a short circuit in the circuit, which indirectly leads to local overheating of the battery and triggers a thermal runaway. The rainwater triggering mechanism and the overload protection mechanism can automatically cut off the power supply when it rains, thereby preventing the device from running in rainy conditions that may cause short circuits and overheating, further improving the versatility and applicability of the device, increasing the service life of the device, and reducing the maintenance and manufacturing costs for the user.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0044] See alsoFigures 1 to 16 The application provides a technical scheme: an outdoor energy storage device of a photovoltaic power station user, which comprises an outdoor power supply 1, an overload protection mechanism 2 arranged on one side of the inner wall of the outdoor power supply 1 and used for providing a protection function for the device when the temperature inside the device is too high, and a rainwater triggering mechanism 3 arranged on the top of the overload protection mechanism 2 and used for automatically triggering the overload protection mechanism 2 to provide protection for the device when it is raining.

[0045] The overload protection mechanism 2 comprises an outer shell body 201 installed on the top of the inner wall of the outdoor power supply 1, the inner wall of the outer shell body 201 is provided with an inner shell body 202, the top of the inner shell body 202 is provided with a limiting clamp rod 203, one end of the limiting clamp rod 203 is provided with a connecting block 204, and the inner wall of the connecting block 204 is movably provided with a triggering ball 205.

[0046] The rainwater triggering mechanism 3 comprises a pressing block 301 movably installed on the top of the triggering ball 205, the outer wall of the pressing block 301 is movably provided with an offset connecting rod 302, one end of the offset connecting rod 302 is connected with a movable connecting rod 303, and the outer wall of the movable connecting rod 303 is provided with a connecting sliding groove 304.

[0047] As the embodiment, hot weather can cause the temperature inside the outdoor power supply 1 to be high, so that the temperature of the wind blown out of the heat dissipation opening 209 is high, the high-temperature wind is discharged into the outer wall of the limiting clamp rod 203 through the air outlet pipe 210, the limiting clamp rod 203 expands when heated, so that the inner diameter of the limiting clamp rod 203 becomes larger, when the inner diameter of the limiting clamp rod 203 becomes larger, the connecting block 204 is slightly stretched, and the triggering ball 205 is separated from the outer wall of the limiting clamp rod 203 and falls to the inner wall of the inner shell body 202 (the diameter of the limiting clamp rod 203 in the initial state is slightly smaller than the diameter of the triggering ball 205, so that the triggering ball 205 is clamped on the outer wall of the limiting clamp rod 203 and cannot move).

[0048] The outer wall of the triggering ball 205 is connected with a reset rod 206, the bottom of the inner wall of the outer shell body 201 is provided with a press switch 207, the bottom of the press switch 207 is provided with a storage battery 208, one side of the outer shell body 201 is provided with a heat dissipation opening 209, and the outside of the heat dissipation opening 209 is connected with an air outlet pipe 210.

[0049] As this embodiment, the inner wall of the inner shell 202 slides downward and presses the push switch 207. After being pressed, the push switch 207 will send an electrical signal to the battery 208 to stop the battery 208, thereby stopping the operation of the outdoor power supply 1. After the temperature of the outdoor power supply 1 returns to normal, the user only needs to hold one end of the reset rod 206 from the outer wall of the outdoor power supply 1 and pull it upward, and drive the trigger ball 205 to move through the reset rod 206. When the trigger ball 205 moves to the limit clamp rod 203, the trigger ball 205 will squeeze the limit clamp rod 203 to open the limit clamp rod 203. When the limit clamp rod 203 opens, the connecting block 204 will also stretch slightly. After that, after dragging the trigger ball 205 to its original position, the connecting block 204 will reset and drive the limit clamp rod 203 to reset and re-lock the trigger ball 205 (the user can reset the trigger ball 205 by holding the reset rod 206 after the device is powered off, thereby restarting the device).

[0050] One end of the pressing block 301 is connected to a telescopic rod 305, and a spring 306 is arranged around the outer wall of the telescopic rod 305. One end of the telescopic rod 305 is connected to a receiving bin 307, and a water pipe 308 is installed on the top of the receiving bin 307. A water collecting tray 309 is provided at one end of the water pipe 308. A drain pipe 310 is provided on one side of the outer wall of the receiving bin 307, and a connecting telescopic rod 311 is installed on the outer wall of the water pipe 308.

[0051] As in this embodiment, the amount of rainwater received in the receiving chamber 307 gradually increases, which causes the weight of the receiving chamber 307 to increase. The increased pressure of the receiving chamber 307 will compress the telescopic rod 305 and the spring 306 to contract and drive the pressure block 301 to move downward. When the pressure block 301 moves downward, it will drive the offset link 302 to rotate. When the offset link 302 rotates, one end of the offset link 302 will drive the movable link 303 to slide to one side. When the movable link 303 slides, due to the contact between the movable link 303 and the limit When the clamp rod 203 is connected, it will drive the limit clamp rod 203 to rotate slightly, so that the inner diameter of the limit clamp rod 203 becomes larger (the rainwater is used to change the weight of the receiving bin 307, so that the receiving bin 307 can drive the limit clamp rod 203 to move through the telescopic rod 305 and spring 306, the pressure block 301 and the offset link 302, and the movable link 303, thereby increasing the inner diameter of the limit clamp rod 203, causing the trigger ball 205 to fall onto the press switch 207 and stop the equipment from running).

[0052] The limiting clamping rods 203 are all movably connected through a rotating shaft. The limiting clamping rods 203 are made of metal. The connecting blocks 204 are connected to both ends of the limiting clamping rods 203.

[0053] As the embodiment, when the movable connecting rod 303 slides, the movable connecting rod 303 is connected with the limiting clamp rod 203, so that the limiting clamp rod 203 is slightly rotated, the inner diameter of the limiting clamp rod 203 is increased, the connecting block 204 is slightly stretched, the trigger ball 205 continues to fall, and the storage battery 208 stops running.

[0054] The connecting block 204 is a cuboid, and the material of the connecting block 204 is an elastic material.

[0055] As the embodiment, the connecting block 204 is made of silicone rubber, which has excellent high and low temperature resistance, and the working temperature range can reach-60℃-250℃. The connecting block 204 can still maintain good elasticity and flexibility in a high temperature environment, so that the connecting block 204 has the functions of deformation and reset (the limiting clamp rod 203 is in a movable state due to the special material of the connecting block 204, but the material characteristics of the connecting block 204 make the limiting clamp rod 203 not move in a normal state).

[0056] The outer wall of the movable connecting rod 303 is connected with the outer wall of the limiting clamp rod 203, and the movable connecting rod 303 is matched with the connecting sliding groove 304.

[0057] As the embodiment, when the movable connecting rod 303 slides, the movable connecting rod 303 is connected with the limiting clamp rod 203, so that the limiting clamp rod 203 is slightly rotated, the inner diameter of the limiting clamp rod 203 is increased, the connecting block 204 is slightly stretched, the trigger ball 205 continues to fall, and the storage battery 208 stops running.

[0058] One end of the offset connecting rod 302 is movably connected with the outer wall of the pressing block 301, and the other end of the offset connecting rod 302 is movably connected with one end of the movable connecting rod 303.

[0059] As the embodiment, the weight of the receiving bin 307 increases the pressure, which compresses the telescopic rod 305 and the spring 306 to shrink and drives the pressing block 301 to move downward. When the pressing block 301 moves downward, the offset connecting rod 302 is rotated, and one end of the offset connecting rod 302 drives the movable connecting rod 303 to slide to one side.

[0060] The outer wall of the outer shell 201 and the outer wall of the inner shell 202 are provided with sliding grooves, and the diameters of the sliding grooves of the outer shell 201 and the inner shell 202 are matched with the diameter of the reset rod 206.

[0061] As the embodiment, the trigger ball 205 is displaced by the reset rod 206, when the trigger ball 205 is displaced to the position of the limiting clamp rod 203, the trigger ball 205 will squeeze the limiting clamp rod 203 so that the limiting clamp rod 203 is opened, when the limiting clamp rod 203 is opened, the connecting block 204 is also slightly stretched, then the trigger ball 205 is dragged to the original position, the connecting block 204 is reset to reset the limiting clamp rod 203 to re-catch the trigger ball 205.

[0062] The pressing switch 207 is aligned with the bottom of the trigger ball 205, the pressing switch 207 and the battery 208 are electrically connected through electrical signals.

[0063] As the embodiment, the trigger ball 205 will fall off to the inner wall of the inner shell 202, slide downward through the inner wall of the inner shell 202 and press the pressing switch 207, the pressing switch 207 will send an electrical signal to the battery 208 after being pressed to make the battery 208 stop, so that the outdoor power supply 1 stops running.

[0064] The two sides of the receiving bin 307 are provided with sliding blocks and sliding grooves which are matched with each other, and the bottom of the outer wall of the receiving bin 307 is connected with one end of the telescopic rod 305.

[0065] As the embodiment, the water collecting disc 309 will drain the rainwater through the water pipe 308 into the inner wall of the receiving bin 307, as the rainwater received in the receiving bin 307 gradually increases, the weight of the receiving bin 307 will also increase, and the pressure of the weight of the receiving bin 307 will compress the telescopic rod 305 and the spring 306 to shrink and drive the pressing block 301 to move downward.

[0066] Working principle: when using the outdoor energy storage device of the photovoltaic power station, first, if the outdoor power supply 1 encounters hot weather during daily work, the internal temperature of the outdoor power supply 1 will be high, so that the temperature of the wind blown out at the heat dissipation port 209 is high, the high-temperature wind is discharged to the outer wall of the limiting clamp rod 203 through the air outlet pipe 210, the limiting clamp rod 203 will expand when heated, causing the inner diameter of the limiting clamp rod 203 to increase, when the inner diameter of the limiting clamp rod 203 increases, the connecting block 204 will be slightly stretched, and without the limiting of the limiting clamp rod 203, the trigger ball 205 will fall off to the inner wall of the inner shell 202, slide downward and press the press switch 207, the press switch 207 will send an electrical signal to the battery 208 after being pressed, so that the battery 208 stops, so that the outdoor power supply 1 stops running, and after the temperature of the outdoor power supply 1 returns to normal, the user only needs to hold one end of the reset rod 206 upward from the outer wall of the outdoor power supply 1, and displace the trigger ball 205 through the reset rod 206, when the trigger ball 205 is displaced to the limiting clamp rod 203, the trigger ball 205 will squeeze the limiting clamp rod 203 to make the limiting clamp rod 203 open, when the limiting clamp rod 203 opens, the connecting block 204 will also be slightly stretched, and then the trigger ball 205 is dragged to the original position, the connecting block 204 is reset to drive the limiting clamp rod 203 to reset and re-clamp the trigger ball 205;

[0067] Finally, when it rains, the rainwater will be collected by the water collector 309, and the water collector 309 will discharge the rainwater through the water pipe 308 to the inner wall of the receiving bin 307. As the amount of rainwater collected in the receiving bin 307 increases, the weight of the receiving bin 307 also increases. The increase in the weight of the receiving bin 307 will compress the telescopic rod 305 and the spring 306 to shrink and drive the pressing block 301 to move downward. The pressing block 301 will drive the offset connecting rod 302 to rotate when moving downward, and one end of the offset connecting rod 302 will drive the movable connecting rod 303 to slide to one side when rotating. The movable connecting rod 303 will slightly rotate the limiting clamp rod 203 to increase the inner diameter of the limiting clamp rod 203 when sliding, and the connecting block 204 will also be slightly stretched at the same time. At this time, the trigger ball 205 will continue to fall off as described above to stop the battery 208 from running. Then the user continues to hold the reset rod 206 upward to reset the trigger ball 205, and then opens one end of the drain pipe 310 to discharge the rainwater in the receiving bin 307. After the weight of the receiving bin 307 returns to normal, the telescopic rod 305 and the spring 306 will drive the pressing block 301 to reset, so that the movable connecting rod 303 is reset.

[0068] Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalent features, by those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
