Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and in particular to an electrical fire early warning device for a rural homestay. Background Art

[0002] With the continuous advancement of science and technology, various regions are vigorously promoting light and heavy industries to further promote economic development. To meet the production needs of heavy industry, large amounts of natural resources and land are required, and the production process emits pollutants, which inevitably have a certain impact on the environment. To reduce environmental impact, tourism, which directly utilizes the local environment and natural resources, is gaining popularity. With the development of tourism, local homestays have also seen rapid growth. Many homestays are renovated from ordinary homes, adding local folk customs. However, the installation of numerous electrical appliances such as lighting during renovations requires electrical system modifications to achieve unified control. Fire safety also requires electricity supply. Safety equipment such as smoke and carbon monoxide alarms can effectively prevent fires and carbon monoxide poisoning. In the event of a dangerous situation, these alarms can sound an alert in a timely manner, buying valuable time for guests and homestay staff to arrive, minimizing casualties and property damage.

[0003] The control box of an electrical appliance is the control terminal for all electrical appliances when in use, but it also has certain safety hazards. Some of its connections are loose, and long-term use of large currents will cause an increase in heat, causing the electrical appliances to overheat and cause fires. Summary of the Invention

When heated, a trigger component installed at a control terminal causes a trigger block of the trigger component to expand and break due to the heat, allowing the trigger component to slide to release the spray component. At the same time, the trigger component transmits a signal to the control terminal, allowing the storage tank to spray the fire-extinguishing material. After the trigger component triggers the control terminal, the blocking component and the warning strip transmit signals at the same time, causing the blocking component to disconnect, and the warning strip to directly display a warning.

[0012] The present invention provides an electrical fire warning device for a rural homestay, which has the following beneficial effects:

[0013] In the present invention, a collecting component is first installed at the bottom of the box assembly, a control terminal is installed at the top of the box assembly, a blocking component is installed at the top of the main circuit breaker, a warning strip is installed at the outer edge of the box assembly, a sounding component is installed on the left side of the control terminal of the box assembly, and a storage tank is installed on the left side of the control terminal in the box assembly. When the circuit breaker is abnormally heated, high temperature or open flame occurs, the trigger component on the top of the box assembly will be sensed first, and the trigger block of the trigger component adopts a structure that expands and breaks when heated. After the trigger block is broken, the trigger component moves, the spray component is turned on and the trigger component is triggered at the same time. The component transmits the signal to the control terminal, and the control terminal simultaneously transmits the signal to the sound component, blocking component, storage tank and warning strip. The storage tank that receives the signal first will release the fire extinguishing material, which will be sprayed directly onto the circuit breaker through the spray component to extinguish the fire. At the same time, the sound component releases the sound, and the extension frame of the sound component can extend toward the outward end to enhance the diffusion of the warning sound and the effect of increasing the warning. The warning strip can flash. The warning strip adopts a bent right-angle structure, which allows the warning strip to also increase the display warning. The blocking component will receive the signal and disconnect to prevent the fire caused by electric heating from further spreading.

[0014] In addition, the main box body and the baffle plate can be set to the same existing structure, or the baffle plate can be set to a sliding installation structure, and the front end of the main box body is set to a widened structure, so that the widened edge of the main box body can be installed with a warning strip, and the warning strip is set to a bent shape, so that the warning strip can flash when it receives a signal, and a better light warning is formed by the bent warning strip, so that a better warning can be given by light when the sound is noisy.

[0015] In addition, when the device is in use, the fire extinguishing material will be sprayed toward the circuit breaker. At this time, in order to better collect and clean the inside of the box assembly, guide bars are directly set at both ends of the bottom of the collection box, so that the collection box can be better slid and installed according to the guide bars, making the collection box more stable. The collection box is slotted according to the wire hole of the circuit breaker, so that the collection box can increase the access to the fire extinguishing material, thereby facilitating the collection and cleaning of the fire extinguishing material debris as a whole by the collection assembly.

[0016] In addition, the blocking box is fixed to the top line entry position of the main circuit breaker through the contact piece extending from the bottom. At this time, the external cable is connected to the blocking box. When the control terminal triggers the signal to the blocking box, the blocking box can connect and disconnect the end cable, thereby quickly cutting off the line and avoiding the spread of heat or fire.

[0017] In addition, when the control terminal triggers a signal to the sound-emitting component, the general sound-emitting block will make a sound directly, and the sound-emitting block inside the box component will be blocked, so that an extension frame is set on the sound-emitting block, and the end of the extension frame is extended directly to the outer end of the box component. The end of the extension frame is set to a structure that is through-through from top to bottom, so that the sound of the sound-emitting block can be exported through the extension frame. When dust falls on the outside, it can pass through the end of the extension frame that is through-through from top to bottom, making it easier to clean it later.

[0018] In addition, the trigger plate is first slidably installed on the spray assembly so that the trigger plate can block the spray port of the spray assembly. The outer end of the trigger plate is connected to the connecting frame. A groove structure is provided on the wall of the connecting frame, and the connecting block on the connecting frame is provided with a column. The connecting block is clamped in the groove of the connecting frame through the column. The connecting frame is arranged in multiple groups, so that the connecting block can be clamped in any position of the connecting frame through the column, which makes it convenient for the connecting block and the connecting frame to be adjusted. The fixed block is directly fixed on the guide rail at the bottom of the spray assembly, and the transmission block is slidably installed on the guide rail. A spring is added between the transmission block and the fixed block, and the transmission block is fixed to the connection block. When in use, the trigger block is first installed on the transmission block. When the trigger block expands due to heat, the trigger block will expand and break. The transmission block will slide through the spring, so that the transmission block drives the connection block to move, and the connecting frame slides the trigger plate to the spray assembly to open the spray port of the spray assembly, so that the storage tank can be injected into the spray assembly from the spray port, thereby realizing the cooling and fire extinguishing effect of the spray assembly on the circuit breaker.
