Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, and in particular to an early warning device. Background Technology

[0002] Spare parts inventory is a key support link for enterprise production and operation, and its safety is directly related to production continuity and equipment maintenance efficiency. With the increasing diversification of industrial spare parts (such as metal processing parts, plastic products, oil lubricants, etc.), spare parts warehouses often store a large number of flammable and combustible materials, and due to complex spatial layout, dense stacking of shelves, or differences in ventilation conditions, they are prone to forming local high temperature environments.

[0003] In related technologies, traditional spare parts inventory early warning technology mainly relies on smoke detectors. The working principle of smoke detectors is to trigger an alarm by detecting the concentration of smoke particles in the air. However, in the early stage of a fire in a spare parts warehouse (before reaching the ignition point), it usually only manifests as a local temperature rise, without open flames or smoke generation. At this time, smoke detectors cannot effectively identify risks, resulting in poor early warning effects. Utility Model Content

[0004] The purpose of this invention is to provide an early warning device that can effectively identify fire risks and improve the early warning effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An early warning device, comprising:

[0007] The export component has a fan fixedly connected to its inner wall.

[0008] The warning mechanism includes a warning indication component and a warning triggering component. The warning indication component includes a heat pipe and a connector. The heat pipe is installed at the end of the outlet component away from the fan. The connector is located on the heat pipe and has a sealing block inside. The sealing block has a solidified state and a molten state. When the sealing block is in a solidified state, it can seal the connector to disconnect it from the heat pipe. When the sealing block is in a molten state, it can separate from the connector to allow the connector to connect with the heat pipe. The warning triggering component is fixedly connected to the end of the heat pipe away from the outlet component. The warning triggering component can selectively connect with or disconnect from the heat pipe. When the warning triggering component is disconnected from the heat pipe, it can issue a warning signal.

[0009] Preferably, the warning mechanism further includes a warning end, one end of which is fixedly connected to the inner wall of the outlet component, and the other end of which is fixedly connected to the heat-conducting pipe. The interior of the warning end is conical, and the inner diameter of the warning end gradually decreases from the outlet component to the heat-conducting pipe.

[0010] Preferably, the warning end and the heat pipe are integrally formed structural components.

[0011] Preferably, multiple connectors are provided, and the multiple connectors are distributed at intervals along the axis of the heat pipe.

[0012] Preferably, the inner wall of the heat pipe is fixedly connected with multiple guide strips, which are spiral in shape.

[0013] Preferably, the warning triggering component includes:

[0014] Connecting pipe, which is fixedly connected to the heat-conducting pipe;

[0015] The air intake chamber is fixedly connected to the outer surface of the connecting pipe, and a sealing ring is fixedly connected to the inner wall of the air intake chamber. The sealing ring, the connecting pipe and the air intake chamber enclose and form a receiving cavity.

[0016] The blocking ball is located inside the receiving cavity and can slide relative to the air intake chamber so that the blocking ball blocks the blocking ring or connects the blocking ring with the receiving cavity.

[0017] Preferably, the warning triggering component also includes an alarm trigger, which is fixedly connected to the inner wall of the air intake chamber. The alarm trigger and the plugging ball are located on opposite sides of the plugging ring along the axial direction. When the plugging ball plugs the plugging ring, the plugging ball can trigger the alarm trigger.

[0018] Preferably, the early warning triggering component further includes a guide sleeve and a guide rod. The guide sleeve is fixedly connected to the inner wall of the connecting pipe, the guide rod is slidably connected to the inner wall of the guide sleeve, and one end of the guide rod is fixedly connected to the blocking ball.

[0019] Preferably, the surface of the guide rod is fitted with an elastic element, one end of which is connected to or abuts against the inner wall of the air intake chamber, and the other end of which is connected to or abuts against the sealing ball.

[0020] Preferably, the connector is a copper whistle connector.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides an early warning device in which, in the initial state, the sealing block is solidified, completely sealing the channel between the connector and the heat-conducting pipe, and the entire system is in a closed state. At this time, the early warning triggering component is disconnected from the heat-conducting pipe, and since the entire system is not started, the early warning triggering component does not issue an early warning signal. When the external temperature rises, the fan is activated to create a pressure difference. At this time, the early warning triggering component is connected to the heat-conducting pipe, and the outside atmosphere can enter the heat-conducting pipe through the early warning triggering component. Heat is conducted to the connector through the heat-conducting pipe. As the temperature continues to rise, the sealing block begins to soften and eventually melts. When the temperature inside the heat-conducting pipe reaches the melting point of the sealing block or the temperature below the heat-conducting pipe reaches the melting point of the sealing block, the sealing block is in a molten state and loses its sealing ability. At this time, the connector and the heat-conducting pipe are connected. Under the action of the fan, airflow will enter the heat-conducting pipe through the connector, reducing the airflow entering the heat-conducting pipe through the early warning triggering component. At this time, the early warning triggering component is disconnected from the heat-conducting pipe and can issue an early warning signal.

[0023] When the outside temperature rises, the sealing block melts, and the connection between the connector and the heat pipe becomes conductive. At this time, the early warning triggering component can issue an early warning signal, which can promptly remind the operator to take measures. It does not rely on open flames or smoke, but can trigger the early warning based solely on temperature changes. That is, it can issue an alarm before a fire occurs or smoke forms, which greatly improves the response time, effectively identifies fire risks, and improves the early warning effect.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figure 1-4As shown, an embodiment of this utility model provides an early warning device, including an outlet component 1 and an early warning mechanism 3. A fan 2 is fixedly connected to the inner wall of the outlet component 1. The early warning mechanism 3 includes an early warning prompt component 32 and an early warning trigger component 33. The early warning prompt component 32 includes a heat-conducting pipe 321 and a connector 322. The heat-conducting pipe 321 is installed at the end of the outlet component 1 away from the fan 2. The connector 322 is disposed on the heat-conducting pipe 321. A sealing block 324 is provided inside the connector 322. The sealing block 324 has a solidified state and a molten state. The sealing block 324 is in a state of... In its solidified state, the sealing block 324 can seal the connector 322, thus disconnecting the connector 322 from the heat pipe 321. When the sealing block 324 is in its molten state, it can separate from the connector 322, allowing the connector 322 to connect with the heat pipe 321. The warning trigger component 33 is fixedly connected to the end of the heat pipe 321 furthest from the outlet component 1. The warning trigger component 33 can selectively connect to or disconnect from the heat pipe 321. When the warning trigger component 33 disconnects from the heat pipe 321, it can issue a warning signal. Specifically, the outlet component 1 is an outlet pipe used to guide airflow; the fan 2 is a suction fan; and the sealing block 324 is a wax block.

[0035] In the initial state, the sealing block 324 is solidified, completely sealing the channel between the connector 322 and the heat pipe 321, and the entire system is in a closed state. At this time, the warning trigger component 33 is disconnected from the heat pipe 321, and since the entire system is not started, the warning trigger component 33 does not issue a warning signal. When the outside temperature rises, the fan 2 is activated to create a pressure difference. At this time, the warning trigger component 33 is connected to the heat pipe 321, and the outside atmosphere can enter the heat pipe 321 through the warning trigger component 33. Heat is conducted to the connector 322 through the heat pipe 321. As the temperature continues to rise, the sealing block 324 begins to soften and eventually melts. When the temperature inside the heat pipe 321 reaches the melting point of the sealing block 324 or the temperature below the heat pipe 321 reaches the melting point of the sealing block 324, the sealing block 324 is in a melting state and loses its sealing ability. At this time, the connector 322 is connected to the heat pipe 321. Under the action of the fan 2, the airflow will enter the heat pipe 321 through the connector 322, which reduces the airflow entering the heat pipe 321 by the warning trigger component 33. At this time, the warning trigger component 33 is disconnected from the heat pipe 321 and can issue a warning signal.

[0036] When the outside temperature rises, the sealing block 324 melts, and the connector 322 and the heat pipe 321 become connected. At this time, the early warning triggering component 33 can issue an early warning signal, which can promptly remind the operator to take measures. It does not rely on open flames or smoke, but can trigger the early warning based solely on temperature changes. That is, it can issue an alarm before a fire occurs or smoke forms, which greatly improves the response time, effectively identifies fire risks, and improves the early warning effect.

[0037] Optionally, the heat pipe 321 is a heat-conducting copper pipe. Heat-conducting copper pipes not only have excellent thermal conductivity but can also be bent arbitrarily. Bending and connecting them according to different usage areas can achieve an early warning function.

[0038] Furthermore, multiple connectors 322 are provided, and the multiple connectors 322 are distributed at intervals along the axis of the heat pipe 321.

[0039] The connectors 322 at different positions along the axis of the heat pipe 321 can monitor the temperature changes in different areas. When the local temperature is abnormal, the sealing block 324 near the heat source melts first, thereby triggering the action of the early warning trigger component 33 to accurately locate the risk point.

[0040] Heat sources in the spare parts warehouse may be dispersed or mobile. The distribution of multiple connectors 322 can cover a wider monitoring range and reduce the risk of "missed detection". At the same time, if a single connector 322 or sealing block 324 fails, the other connectors 322 can still work independently, avoiding overall system failure and improving equipment reliability.

[0041] Preferably, connector 322 is a copper whistle connector. With this configuration, when the sealing block 324 melts, airflow is allowed to pass through the copper whistle connector into the heat pipe 321. The copper whistle connector can emit a "whistle" to indicate the specific high-temperature area, making it easier for operators to take timely measures, reduce the possibility of fire, and improve the early warning effect.

[0042] Furthermore, multiple guide strips 323 are fixedly connected to the inner wall of the heat pipe 321, and the multiple guide strips 323 are spiral in shape.

[0043] like Figure 2 and Figure 3 As shown, two guide strips 323 are provided. The spiral guide strips 323 can guide the airflow to be transmitted spirally along the axial direction, which will guide the airflow evenly and avoid the accumulation or dissipation of heat in local areas. The gas inside the heat pipe 321 is heated as a whole, and the sealing block 324 inside the adjacent connector 322 gradually melts, thereby triggering the warning trigger component 33 to issue a warning signal. In other embodiments, three, four or more guide strips 323 may also be provided.

[0044] Furthermore, the warning mechanism 3 also includes a warning end 31, one end of which is fixedly connected to the inner wall of the outlet member 1, and the other end of which is fixedly connected to the heat conduction pipe 321. The interior of the warning end 31 is conical, and the inner diameter of the warning end 31 gradually decreases from the outlet member 1 to the heat conduction pipe 321.

[0045] By setting the warning end 31, it is easy to install the heat pipe 321 on the inner wall of the outlet 1. The warning end 31 is set into a cone shape. After the airflow in the heat pipe 321 enters the warning end 31, it will diffuse and then be discharged from the outlet 1 through the fan 2. The diffusion effect of the cone end increases the contact area between the airflow and the blades of the fan 2, avoiding the problem of uneven load on the fan 2 caused by excessive local airflow speed.

[0046] Furthermore, the warning end 31 and the heat pipe 321 are integrally formed structural components. This integral forming reduces the need for parts processing, assembly, welding, and other procedures, thereby improving production efficiency and reducing manufacturing costs, making it particularly suitable for mass production.

[0047] Furthermore, such as Figure 4 As shown, the early warning triggering component 33 includes a connecting pipe 331, an air inlet chamber 332, and a blocking ball 336. The connecting pipe 331 is fixedly connected to the heat conduction pipe 321, and the air inlet chamber 332 is fixedly connected to the outer surface of the connecting pipe 331. A blocking ring 333 is fixedly connected to the inner wall of the air inlet chamber 332. The blocking ring 333, the connecting pipe 331, and the air inlet chamber 332 enclose a receiving cavity. The blocking ball 336 is disposed in the receiving cavity. The blocking ball 336 can slide relative to the air inlet chamber 332 so that the blocking ball 336 blocks the blocking ring 333, or makes the blocking ring 333 communicate with the receiving cavity.

[0048] In the initial state, the warning trigger component 33 is disconnected from the heat pipe 321. At this time, the sealing ball 366 seals the sealing ring 333. As the fan 2 starts, the air pressure on the sealing ring 333 on the side of the sealing ball 336 is lower than the outside atmospheric pressure. At this time, the outside atmosphere will push the sealing ball 336 to move towards the connecting pipe 331, so that the sealing ring 333 is connected to the receiving cavity of the air inlet chamber 332, and the outside atmosphere enters the heat pipe 321 through the air inlet chamber 332. When the airflow temperature entering the heat pipe 321 melts the sealing block 324 inside the connector 322, the inside of the connector 322 connects with the heat pipe 321. The airflow below the connector 322 enters the heat pipe 321 through the connector 322, reducing the airflow entering the heat pipe 321 from the air inlet chamber 332. This means the air pressure on the sealing ring 333 side of the sealing ball 336 is higher than the external atmospheric pressure. Driven by this pressure difference, the sealing ball 336 seals the sealing ring 333. When the sealing ball 336 seals the sealing ring 333, the early warning trigger component 33 is triggered to issue an early warning signal, reminding the operator to take action.

[0049] Furthermore, the warning triggering component 33 also includes an alarm trigger 334, which is fixedly connected to the inner wall of the air intake chamber 332. The alarm trigger 334 and the blocking ball 336 are located on opposite sides of the blocking ring 333 along the axis. When the blocking ball 336 blocks the blocking ring 333, the blocking ball 336 can trigger the alarm trigger 334.

[0050] When the sealing block 324 melts and connects the heat pipe 321 to the connector 322, the airflow pushes the sealing ball 336 to move and seal the sealing ring 333. At this time, the sealing ball 336 triggers the alarm trigger 334, which sounds an alarm to remind the operator to identify the risk in time and take measures. Combined with the sound emitted by the connector 332, the risk location can be accurately located.

[0051] Specifically, the alarm trigger 334 includes a micro switch. When the blocking ball 336 blocks the blocking ring 333, it squeezes the contact, causing the circuit to conduct and triggering an alarm. After the blocking ball 336 disengages from the blocking ring 333, the contact resets, and the alarm stops. It should be noted that the micro switch is prior art in this field and will not be described in detail here.

[0052] Furthermore, the early warning triggering component 33 also includes a guide sleeve 338 and a guide rod 337. The guide sleeve 338 is fixedly connected to the inner wall of the connecting pipe 331, and the guide rod 337 is slidably connected to the inner wall of the guide sleeve 338. One end of the guide rod 337 is fixedly connected to the blocking ball 336.

[0053] When the blocking ball 336 moves, the guide rod 337 slides synchronously within the guide sleeve 338. The guide rod 337, through the cooperation of the guide sleeve 338, can guide the blocking ball 336, ensuring the stability of the blocking ball 336's movement and avoiding displacement deviation during movement, which could lead to incomplete sealing.

[0054] Furthermore, an elastic element 335 is fitted onto the surface of the guide rod 337. One end of the elastic element 335 is connected to or abuts against the inner wall of the air intake chamber 332, and the other end of the elastic element 335 is connected to or abuts against the sealing ball 336. Specifically, the elastic element 335 is a compression spring.

[0055] In the initial state, the elastic element 335 is compressed, and its own elastic force pushes the sealing ball 336 to seal the sealing ring 333, ensuring that the warning trigger component 33 is completely disconnected from the heat pipe 321 to prevent false triggering. When the external temperature rises and the sealing block 324 in the connector 322 melts, the connector 322 is connected to the heat pipe 321, and the outside atmosphere can enter the heat pipe 321 through the connector 322. At this time, the air pressure in the heat pipe 321 is higher than the air pressure on the side of the sealing ring 333 away from the connector 331. Driven by the air pressure difference and the reset action of the elastic element 335, the sealing ball 336 quickly seals the sealing ring 333 and actuates the alarm trigger 334.

[0056] like Figure 4 As shown, the elastic element 335 is conical, which facilitates its relative fixation between the inner wall of the air intake chamber 332 and the sealing ball 336.

[0057] The working process of the early warning device provided by this utility model is as follows:

[0058] In use, fan 2 is activated, causing gas to flow from the air inlet chamber 332 towards the warning end 31. The airflow passes through the sealing ring 333, pushing the sealing ball 336 towards the connecting pipe 331. At this time, the sealing ball 336 is connected to the sealing ring 333. As the airflow passes through, the sealing ball 336 moves towards the connecting pipe 331, compressing the elastic element 335. The movement of the sealing ball 336 drives the guide rod 337 to move together. The guide rod 337, through the cooperation of the guide sleeve 338, can guide the sealing ball 336. The heat pipe 321 guides the airflow. When heat is generated below the heat pipe 321, the connector 322 heats up accordingly. The seal inside the connector 322... When the plug 324 melts, the connector 322 connects to the heat pipe 321, and the airflow enters the heat pipe 321 through the connector 322. The connector 322 will emit a whistle, and at the same time, the airflow velocity in the air intake chamber 332 will gradually decrease. Under the action of the elastic element 335, the blocking ball 336 moves towards the blocking ring 333, and then the blocking ball 336 blocks the blocking ring 333 and will push against and trigger the alarm trigger 334. The alarm trigger 334 will sound an alarm. The operator can accurately find the risk area according to the location of the whistle, so that the operator can take timely measures. The fire risk can be identified without waiting for open flame or smoke to be generated, thus improving the fire early warning effect.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
