Description

Technical Field

[0001] This utility model relates to the field of overload alarm technology, specifically a power supply device with overload alarm. Background Technology

[0002] Overload is one of the most common faults in power supply systems. Long-term or instantaneous overload can not only cause the power module to heat up and reduce efficiency, but may also cause serious consequences such as component burnout, circuit aging and even fire. Therefore, it is very important to achieve rapid detection, early warning and protection against overload.

[0003] A search revealed a Chinese patent with publication number CN222484297U, which discloses an overload protection device for a switching power supply. The device includes a base and a protective cover. The base has a protector body on top, and a transmission rod is fixedly connected to the top of the protector body. A lamp holder is fixedly connected to the top of the protective cover, and a warning light is mounted on the top of the lamp holder. A copper rod is fixedly connected to the bottom of the lamp holder. Through the arrangement of the base, protector body, protective cover, transmission rod, warning light, and copper rods, the outer wall of the transmission rod contacts the two copper rods. Leakage current from the protector body is transmitted through the transmission rod to the copper rods, and then to the lamp holder. The internal circuit of the lamp holder is connected, causing the warning light to illuminate. Operators can determine whether there is current on the surface of the protector body based on whether the warning light is on, thus enabling the device to detect leakage current itself and greatly improving safety.

[0004] In the aforementioned technologies, although the design of structures such as power transmission poles and warning lights can detect whether there is a power leakage, in actual use, if the power leakage is caused by power overload, the warning light will only flash once, making it difficult for staff to notice. This makes it easy to overlook the power overload situation, thus leaving a safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a power supply device with an overload alarm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power supply device with overload alarm, including a protective cover, and further comprising:

[0007] The battery pack is located inside the protective cover.

[0008] There are four hollow columns, which are fixedly connected to the inner wall of the protective cover.

[0009] A sliding rod is slidably connected to one end of a hollow column, and a clamping plate is fixedly connected to one end of the sliding rod.

[0010] A liquid storage tube is fixedly connected to the top of the protective cover. The liquid storage tube is connected to the hollow column, and a float plate is slidably connected to one end of the inner wall of the liquid storage tube.

[0011] The power switch is fixedly connected to the top of the inner wall of the liquid storage tube.

[0012] Preferably, the bottom of the liquid storage tube is connected to four connecting pipes, the connecting pipes are connected to the hollow column, and the top of the float is fixedly connected to a top rod.

[0013] Preferably, the slide bar is fixedly connected to a movable block inside the hollow column, the movable block is slidably connected to the hollow column, and a spring is fixedly connected to one end of the clamping plate, the spring being fixedly connected to the protective cover.

[0014] Preferably, an alarm is fixedly connected to one end of the top of the protective cover, and the alarm is electrically connected to a power switch.

[0015] Preferably, a conductive rod is fixedly connected to the inner wall of the protective cover below the alarm, and a conductive plate is fixedly connected to the bottom of the conductive rod. The conductive rod is electrically connected to the alarm.

[0016] Preferably, one end of the side wall of the protective cover is provided with multiple heat dissipation holes, and a gate is slidably connected to the protective cover at the heat dissipation holes.

[0017] Preferably, an electric push rod is fixedly connected to one end of the protective cover adjacent to the gate, and the output end of the electric push rod is fixedly connected to the gate.

[0018] Preferably, a controller is fixedly connected to one end of the side wall of the protective cover, and a temperature sensor is fixedly connected to one end of the inner wall of the protective cover. The controller is electrically connected to the temperature sensor, the alarm, and the electric push rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention stores damping fluid in a storage tube and clamps the battery block with a clamping plate. When the battery block is overloaded and expands and deforms, it will squeeze the clamping plate. At this time, the sliding rod and the moving block will move towards the side wall of the protective cover, thereby pushing the damping fluid in the hollow column to flow back to the storage tube through the connecting pipe. At this time, the amount of damping fluid in the storage tube increases, causing the liquid level to rise, which in turn drives the float and the top rod to move upward. When the top rod contacts the power switch, the alarm will sound.

[0021] This invention uses a controller design to ensure that the alarm keeps sounding when the battery pack is overloaded, making it easier for staff to be alerted. In addition, the electric push rod design can move the gate to block the heat dissipation holes, thus preventing smoke and flames from escaping through the heat dissipation holes when the battery pack catches fire.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides a technical solution: such as Figures 1-5 The power supply device shown includes a protective cover 1, a battery block 2, a hollow column 3, a sliding rod 4, a liquid storage tube 6, and a power switch 8. The battery block 2 is disposed inside the protective cover 1. Four hollow columns 3 are provided and fixedly connected to the inner wall of the protective cover 1. The sliding rod 4 is slidably connected to one end of the hollow column 3, and a clamping plate 5 is fixedly connected to one end of the sliding rod 4. The liquid storage tube 6 is fixedly connected to the top of the protective cover 1 and communicates with the hollow column 3. A float plate 7 is slidably connected to one end of the inner wall of the liquid storage tube 6. The power switch 8 is fixedly connected to the top of the inner wall of the liquid storage tube 6. Four connecting pipes 9 are connected to the bottom of the liquid storage tube 6 and communicate with the hollow column 3. A top rod 10 is fixedly connected to the top of the float plate 7. An alarm 13 is fixedly connected to one end of the top of the protective cover 1 and is electrically connected to the power switch 8.

[0030] Specifically, during use, damping fluid needs to be injected into the reservoir 6. The damping fluid in the reservoir 6 flows into the hollow column 3 through the connecting pipe 9. When the battery block 2 is overloaded and expands and deforms, the battery block 2 will squeeze the clamping plate 5, thereby pushing the slide rod 4 to move towards the side wall of the protective cover 1, which in turn pushes the damping fluid in the hollow column 3 to flow into the connecting pipe 9. The damping fluid in the connecting pipe 9 will flow back into the reservoir 6. At this time, the amount of damping fluid in the reservoir 6 increases, causing the liquid level to rise, which in turn drives the float 7 and the top rod 10 to move upward. When the top rod 10 contacts the power switch 8, the alarm 13 will sound an alarm, thereby reminding the staff that the battery block 2 is overloaded.

[0031] The slide bar 4 is located inside the hollow column 3 and is fixedly connected to the moving block 11. The moving block 11 is slidably connected to the hollow column 3. One end of the clamping plate 5 is fixedly connected to the spring 12, and the spring 12 is fixedly connected to the protective cover 1.

[0032] Specifically, the movable block 11 can be a rubber piston. The design of the movable block 11 allows the slide bar 4 to smoothly push the damping fluid in the hollow column 3 to flow when it moves towards the protective cover 1. The design of the spring 12 allows the clamping plate 5 to clamp the battery block 2 and also allows the clamping plate 5 to reset.

[0033] A conductive rod 14 is fixedly connected to the inner wall of the protective cover 1 below the alarm 13. A conductive plate 15 is fixedly connected to the bottom of the conductive rod 14. The conductive rod 14 is electrically connected to the alarm 13.

[0034] Specifically, when battery block 2 leaks current, the current will be directly transmitted to alarm 13 through conductive plate 15 and conductive rod 14, thereby causing alarm 13 to sound an alarm.

[0035] The protective cover 1 has multiple heat dissipation holes 16 at one end of its side wall. A gate 17 is slidably connected to the protective cover 1 at the heat dissipation holes 16. An electric push rod 18 is fixedly connected to the protective cover 1 at the end adjacent to the gate 17. The output end of the electric push rod 18 is fixedly connected to the gate 17.

[0036] Specifically, the design of the heat dissipation hole 16 facilitates heat dissipation of the battery block 2, and the design of the electric push rod 18 can push the gate 17 to move, thereby blocking the heat dissipation hole 16, thus preventing smoke and flames from drifting out through the heat dissipation hole 16 when the battery block 2 is burning.

[0037] A controller 19 is fixedly connected to one end of the side wall of the protective cover 1, and a temperature sensor 20 is fixedly connected to one end of the inner wall of the protective cover 1. The controller 19 is electrically connected to the temperature sensor 20, the alarm 13 and the electric push rod 18.

[0038] Specifically, the controller 19 is designed to ensure that the alarm 13 will always sound when the battery block 2 is overloaded, making it easier for staff to be alerted. In addition, the temperature sensor 20 can sense the temperature of the battery block 2. When the battery block 2 is overloaded, the temperature will rise abnormally, which will then transmit an electrical signal to the controller 19, and the controller 19 will control the alarm 13 to sound an alarm.

[0039] Working principle: When in use, damping fluid needs to be injected into the reservoir 6. The damping fluid in the reservoir 6 will flow into the hollow column 3 through the connecting pipe 9. When the battery block 2 is overloaded and expands and deforms, the battery block 2 will squeeze the clamping plate 5, thereby pushing the slide rod 4 and the moving block 11 to move towards the side wall of the protective cover 1, which in turn pushes the damping fluid in the hollow column 3 to flow into the connecting pipe 9. The damping fluid in the connecting pipe 9 will flow back into the reservoir 6. At this time, the amount of damping fluid in the reservoir 6 increases, causing the liquid level to rise, which in turn drives the float 7 and the top rod 10 to move upward. When the top rod 10 contacts the power switch 8, the alarm 13 will sound an alarm, thereby reminding the staff that the battery block 2 is overloaded.

[0040] When battery block 2 leaks current, the current will be directly transmitted to alarm 13 through conductive plate 15 and conductive rod 14, causing alarm 13 to sound an alarm. When battery block 2 is overloaded, the temperature will rise abnormally, which will transmit an electrical signal to controller 19, and controller 19 will control alarm 13 to sound an alarm. When battery block 2 is overloaded, controller 19 will control electric push rod 18 to start, which will drive gate 17 to move, thereby blocking heat dissipation hole 16, thus preventing smoke and flames from drifting out through heat dissipation hole 16 when battery block 2 is burning.
