Description

Technical Field

[0001] This utility model belongs to the field of alarm technology, and in particular relates to a fire alarm for energy storage power stations. Background Technology

[0002] As the global energy structure transitions towards renewable energy, energy storage power stations, as core facilities for mitigating fluctuations in new energy power generation and ensuring stable grid operation, are rapidly expanding in terms of construction scale and application scenarios. Currently, energy storage power stations mainly adopt electrochemical energy storage technologies such as lithium-ion batteries and flow batteries. Among them, lithium-ion batteries have become the mainstream choice due to their high energy density and excellent charge and discharge efficiency. However, during operation, electrochemical energy storage systems are subject to significant fire safety risks due to factors such as battery aging, overcharging and over-discharging, electrolyte leakage, and external short circuits. According to industry statistics, about 70% of fire accidents in lithium-ion battery energy storage power stations are caused by battery thermal runaway. The thermal runaway process releases toxic gases such as carbon monoxide and hydrogen fluoride, and is accompanied by the risk of deflagration. This can cause equipment damage and casualties in a short period of time, posing a severe challenge to the safe operation of energy storage power stations.

[0003] However, existing fire alarms are often subjected to equipment vibration and temperature fluctuations during use, which can cause bolts to loosen or even fall off. This can cause the alarm to deviate from the preset detection position, resulting in an increased clamping gap. Even a slight displacement of the alarm can cause it to miss the area where combustible gas accumulates, thus delaying the warning opportunity. Utility Model Content

[0004] The purpose of this utility model is to provide a fire alarm for energy storage power stations. By setting a fixing part, it solves the problem that existing fire alarms are often in the process of equipment vibration and temperature fluctuation, and the bolts are prone to loosening or even falling off, causing the alarm to deviate from the preset detection position, resulting in an increased clamping gap. Even a slight displacement of the alarm will cause it to miss the area where combustible gas accumulates, thus delaying the warning time.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fire alarm for an energy storage power station, comprising an alarm and further comprising: a fixing part, wherein a plurality of fixing parts are provided and each fixing part is disposed on the alarm; a limiting part, wherein a plurality of limiting parts are provided and each limiting part is mounted on the fixing part; the fixing part includes a hinge assembly, wherein the hinge assembly is disposed on the alarm; and an adapter assembly, wherein a plurality of adapter assemblies are provided and each adapter assembly is mounted on the hinge assembly; the hinge assembly includes a fixing rod 1 fixedly connected to the alarm, a rotating shaft rotatably connected to the inner wall of the fixing rod 1, a fixing ring fixedly connected to the outer wall of the rotating shaft, a plurality of hinge blocks 1 fixedly connected to the outer wall of the fixing ring, a hinge rod hinged to the side of each hinge block 1 away from the rotating shaft, and a hinge block 2 hinged to the side of each hinge rod away from the rotating shaft; four hinge blocks 1, four hinge rods, and four hinge blocks 2 are provided and arranged in a circular array.

[0007] Furthermore, the limiting part includes a pressing component, which is disposed on the hinge component; and a friction component, which is mounted on the pressing component; both the pressing component and the friction component are located inside the fixed rod.

[0008] Furthermore, the adapter component includes a fixed rod two fixedly connected to the hinge rod, a slide rod one slidably connected to the inner wall of the fixed rod two, a slide rod two fixedly connected to the hinge rod, the slide rod two extending into the slide rod one, an elastic element provided inside the fixed rod two, and an auxiliary component provided on the fixed rod one; the slide rod one is a hollow rod, the elastic element includes a spring one sleeved on the outer wall of the slide rod two, the side of the spring one away from the pivot is fixedly connected to the slide rod one, and the side of the spring one near the fixed rod one is fixedly connected to the hinge rod, the auxiliary component includes a rotary knob fixedly connected to the top of the pivot, the rotary knob is rotatably connected to the fixed rod one; an anti-slip pad is provided on the outer wall of the rotary knob.

[0009] Furthermore, the pressing assembly includes a pressing ring threadedly connected to the outer wall of a fixed rod, a fixed plate fixedly connected to the inner wall of the fixed rod, a connecting ring provided on the fixed rod, the connecting ring being adapted to the fixed rod, and a spring fixedly connected between the connecting ring and the fixed plate; the connecting ring is in contact with the pressing ring.

[0010] Furthermore, the friction assembly includes a plurality of friction plates fixedly connected to the top of the fixed plate, and an inner cohesive ring is fixedly connected to the bottom of the connecting ring; the inner cohesive ring is adapted to the friction plates.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a fixing part, after the alarm is positioned, when the rotary knob is turned, the torque is transmitted to the fixing ring through the rotating shaft, causing the fixing ring to rotate synchronously. At this time, the hinge block one, which is hinged to the fixing ring, pulls the hinge block two through the hinge rod, causing the fixing rod two to retract into the fixing rod one. Finally, the sliding rod one is completely housed in the fixing rod one, forming a "contracted state" to fit the diameter of the reserved hole. After the fixing rod one is inserted into the reserved hole, the rotary knob is flipped in the opposite direction, and the transmission mechanism runs in reverse. The sliding rod one extends out from the fixing rod one and comes into close contact with the inner wall of the reserved hole. Through mechanical extrusion, an "expansion lock" is formed, completing the rigid fixation of the alarm. This ensures that the alarm is always in the preset detection position, avoiding blind spots in smoke and gas detection caused by loosening. This provides a reliable equipment foundation for fire early warning in energy storage power stations and indirectly reduces the emergency response error of risks such as battery thermal runaway.

[0013] 2. By setting a limiting part, after the alarm is fixed, rotating the lower pressure ring will convert the rotational motion into the lower pressure ring sliding downward along the axial direction of the fixed rod 1, since the lower pressure ring is connected to the fixing rod 1 by a thread. As the lower pressure ring moves downward, it generates continuous pressure on the connecting ring, pushing the connecting ring to move downward synchronously. During this process, the spring is compressed and accumulates elastic potential energy, providing a basis for subsequent structural reset. As the connecting ring moves downward, it also drives the inner cohesive ring to move downward together. The inclined surface design of the inner wall of the inner cohesive ring forms a compression with the friction plate during the displacement process. The guiding effect of the inclined surface allows the friction plate to overcome the initial... The gap narrows inward and eventually fits tightly against the outer wall of the shaft. The static friction between the friction plate and the shaft directly restricts the shaft's rotational freedom. As the core transmission component of the pre-fixed structure, the shaft's rotation is constrained, preventing the displacement of telescopic components such as the second fixed rod and the first sliding rod. This blocks the possibility of the alarm loosening or falling off from the transmission source, avoids displacement of fixed components due to vibration, and completely solves the pain point of traditional devices being prone to loosening after long-term use. It ensures that the alarm always maintains the preset detection position and eliminates detection blind spots caused by equipment offset.

An elastic element is provided inside the fixed rod 221, and an auxiliary component is provided on the fixed rod 211.

[0025] The limiting part 3 includes a pressing component 31, which is mounted on the hinge component 21; and a friction component 32, which is mounted on the pressing component 31. Both the pressing component 31 and the friction component 32 are located inside the fixing rod 211. The pressing component 31 includes a pressing ring 311 threadedly connected to the outer wall of the fixing rod 211. A fixing plate 312 is fixedly connected to the inner wall of the fixing rod 211.

[0026] A specific application of this embodiment is as follows: In use, the alarm 111 is placed in the corresponding position, then the fixing rod 211 is aligned with the reserved hole, and then the rotary knob 225 is rotated. At this time, the rotating shaft 212 will rotate accordingly. When the rotating shaft 212 rotates, the fixing ring 213 will also rotate. When the fixing ring 213 rotates, the hinge block 214, the hinge rod 215, and the hinge block 216 will move, thereby retracting the fixing rod 221 into the fixing rod 211. Then, after the sliding rod 222 is completely retracted into the fixing rod 211, the fixing rod 211 is inserted into the reserved hole. Then the rotary knob 225 is flipped, and the sliding rod 222 extends out and contacts the inner wall of the reserved hole. To achieve the effect of fixing the alarm 111, after fixing, rotate the pressure ring 311. At this time, the pressure ring 311 will slide downward through the thread on the fixing rod 211. When the fixing rod 211 slides downward, it will press the connecting ring 313 downward. When the connecting ring 313 is pressed downward, the inner ring 322 will also move downward. At the same time as the connecting ring 313 moves downward, the spring 314 will be compressed to a certain extent. As the inner ring 322 moves downward, it will pull the friction plate 321 inward through the inclined surface on the inner ring 322, so as to contact the outer wall of the rotating shaft 212. Thus, the rotation of the rotating shaft 212 is restricted by friction, thereby preventing the alarm 111 from falling off by preventing the rotation of the rotating shaft 212.
