Independent resident charging early warning cover

Abstract

According to the independent resident charging early warning cover, heat of smoke or fire is concentrated through the body of the early warning cover body, and the fire sensor is located at the top end of the body, so that the fire sensor can easily sense that a charger of an electric bicycle electrically connected with a socket has a fire, and the fire sensor can transmit the signal level of the fire to the outside; and therefore, the effect of timely early warning is achieved. The sprayer can be a normally-closed constant-pressure fire-fighting spray head with the working temperature threshold of 57 DEG C or 68 DEG C. When the high temperature reaches the working temperature threshold value, due to the fact that the sprayer is externally connected with the fire extinguishing agent pipeline, constant pressure of the fire extinguishing agent is kept in the fire extinguishing agent pipeline, the sprayer is communicated with the externally-connected fire extinguishing agent pipeline, the constant-pressure fire extinguishing agent is sprayed out through the sprayer, the fire extinguishing agent controls the fire behavior of the charger of the electric bicycle, and the fire behavior is prevented from being further diffused; and large-area fire property loss caused by large-area fire diffusion is prevented.

Description

Technical Field

[0001] The present application relates to the technical field of fire protection devices, and in particular to an independent residential charging early warning cover. Background Art

[0002] As lithium battery technology matures, the endurance of electric bicycles has greatly increased, and more and more urban and rural residents choose electric bicycles as a short-distance means of transportation. Due to the characteristics of lithium batteries themselves, lithium batteries are prone to thermal failure after aging. In daily use, after some lithium batteries age, battery thermal failure events will occur during the charging process. In real life, due to the thermal failure of lithium batteries, a large current is generated at the charging end, and the large current can cause a fire in the charger. Since the charging places of urban and rural residents are relatively concentrated, the fire is not discovered in time, often causing large-scale fire property losses. For this reason, it is necessary to propose an independent resident charging warning cover to address the defect that traditional electric bicycle charging places do not have fire warning equipment, resulting in large-scale fire property losses.

[0059] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] The present application provides a stand-alone residential charging early warning cover.

[0061] like Figure 1 As shown, in one embodiment of the present application, an independent residential charging warning cover includes a warning cover body 100, a fire sensor 200, a sprinkler 300 and a socket 500.

[0062] The warning cover 100 includes a main body 110 and a bottom plate 120 , wherein the main body 110 is fixedly connected to the bottom plate 120 , and the main body 110 and the bottom plate 120 form an enclosed space, wherein the enclosed space is provided with an opening 130 , and the enclosed space is communicated with the external environment through the opening 130 .

[0063] The fire sensor 200 is disposed at the top of the body 110 , and the fire sensor 200 is disposed close to the bottom plate 120 .

[0064] The sprinkler 300 is disposed at the top of the body 110 , and the sprinkler 300 is disposed close to the bottom plate 120 , the sprinkler 300 and the fire sensor 200 are close to each other, and the sprinkler 300 is externally connected to a fire extinguishing agent pipeline.

[0065] The socket 500 is attached to the inner cavity of the body 110 .

[0066] Specifically, the fire sensor 200 can transmit the signal level to the fire monitoring and early warning information platform, and the platform sends information and telephone notifications to the mobile terminals of relevant fire-fighting engineering personnel.

[0067] The present application relates to an independent residential charging warning cover, which concentrates the heat of smoke or fire through the main body 110 of the warning cover 100, and the fire sensor 200 is at the top of the main body 110, which makes it easier for the fire sensor 200 to sense that the charger of the electric bicycle connected to the socket 500 has a fire, thereby playing a role in timely warning. When the fire sensor 200 senses that the charger of the electric bicycle connected to the socket 500 has a fire, the fire sensor 200 can transmit the signal level of the fire. The sprinkler can select a normally closed constant pressure fire sprinkler head with an operating temperature threshold of 57 degrees Celsius or 68 degrees Celsius. When the high temperature reaches the working temperature threshold, the sprinkler 300 is connected to an external fire extinguishing agent pipeline, and the fire extinguishing agent is kept at a constant pressure in the fire extinguishing agent pipeline. The sprinkler 300 is connected to the external fire extinguishing agent pipeline, and the constant pressure fire extinguishing agent is sprayed through the sprinkler 300. The fire extinguishing agent controls the fire of the charger of the electric bicycle to prevent the fire from spreading further, and prevents the fire from spreading over a large area and causing large-scale fire property losses. In addition to the function of concentrating fire signals, the main body 110 of the early warning cover 100 can further prevent the fire from spreading over a large area when the main body 110 is made of fireproof material.

[0068] like Figure 1 As shown, in one embodiment of the present application, a plane parallel to the bottom plate 120 is defined as a characteristic surface. The intersection of the body 110 and the characteristic surface is a circular ring surface with a notch. The inner diameter of the circular ring surface close to the bottom plate 120 is greater than the inner diameter of the circular ring surface away from the bottom plate 120. The inner cavity of the body 110 has a smooth transition.

[0069] In one embodiment of the present application, the outer diameter of the annular surface close to the bottom plate 120 is greater than the outer diameter of the annular surface away from the bottom plate 120. The outer surface of the body 110 has a smooth transition.

[0070] This embodiment relates to an early warning cover 100. The early warning cover 100 may be a semi-elliptical shell, which is conducive to the concentration of smoke, flames, and temperature at the top of the inner cavity of the early warning cover 100.

[0071] It is worth mentioning that the inner cavity of the main body 110 has a smooth transition, which is conducive to the concentration of smoke, flames and temperature at the top of the inner cavity of the warning cover body 100.

[0072] The outer surface of the body 110 has a smooth transition, which is conducive to the natural sliding of conductive fluids containing impurities such as rainwater, which is conducive to preventing the socket 500 from short-circuiting and catching fire.

[0073] like Figures 2 to 3 As shown, in one embodiment of the present application, the body 110 includes a top arc plate 111, a back plate 112, a first side plate 113, and a second side plate 114. The top arc plate 111 is fixedly connected to the top edge of the back plate 112. The first side plate 113 is fixedly connected to the top arc plate 111. The first side plate 113 is fixedly connected to the side edge of the back plate 112. The second side plate 114 is fixedly connected to the top arc plate 111. The second side plate 114 is fixedly connected to the side edge of the back plate 112.

[0074] In one embodiment of the present application, the bottom plate 120 is fixedly connected to the bottom edge of the back plate 112. The back plate 112 and the bottom plate 120 are perpendicular to each other. The fire sensor 200 is disposed at the vertex of one side of the top arc plate 111 close to the bottom plate 120.

[0075] This embodiment relates to another early warning cover 100. The early warning cover 100 may be a top arc-shaped extended shell, which is conducive to the concentration of smoke, flames, and temperature at the top of the inner cavity of the early warning cover 100.

[0076] It is worth mentioning that the top arc-shaped extension shell is conducive to the concentration of smoke, flames, and temperature at the top of the inner cavity of the warning cover 100. The top arc-shaped extension shell is also conducive to the natural sliding of conductive fluids containing impurities such as rainwater, which is conducive to preventing the socket 500 from short-circuiting and catching fire.

[0077] like Figure 4 As shown, in one embodiment of the present application, the independent residential charging warning cover further includes a clamp 600. The clamp 600 is fixedly connected to the base plate 120. The clamp 600 is arranged at the geometric center of the base plate 120.

[0078] Specifically, the holder 600 can be used to hold the charger and keep the charger relatively fixed to the base plate 120. This helps the fire extinguishing agent sprayed by the sprayer 300 to spray the charger accurately.

[0079] It is worth mentioning that, since there is an angle between the sprinkler 300 and the extension direction of the plumb line, the sprinkler 300 can also perform a spray fire extinguishing operation on an electric bicycle that has failed due to thermal failure.

[0080] In one embodiment of the present application, the clamp 600 includes a base plate 610, a slide plate 620, a first cable-drawing rod 630, and a second cable-drawing rod 640. The base plate 610 is fixedly connected to the bottom plate 120. The first cable-drawing rod 630 is fixedly connected to the base plate 610. The first cable-drawing rod 630 and the side wall of the base plate 610 are perpendicular to each other. The second cable-drawing rod 640 is fixedly connected to the base plate 610. The second cable-drawing rod 640 and the side wall of the base plate 610 are perpendicular to each other. The first cable-drawing rod 630 and the second cable-drawing rod 640 are parallel to each other. The slide plate 620 is sleeved on the first cable-drawing rod 630. The slide plate 620 is sleeved on the second cable-drawing rod 640.

[0081] Specifically, the base plate 610 is fixedly connected to the bottom plate 120, the first cable guide rod 630 and the second cable guide rod 640 are fixedly connected to the side wall of the base plate 610, there is a preset space between the first cable guide rod 630, the second cable guide rod 640 and the bottom plate 120, and the bottom of the slide plate 620 is arranged in the preset space, so that the slide plate 620 can slide between the first cable guide rod 630 and the second cable guide rod 640. A charger is supported between the slide plate 620 and the base plate 610.

[0082] In one embodiment of the present application, the clamp 600 further includes a first recoil spring 650 and a second recoil spring 660. The first free end 631 of the first cable-drawing rod 630 is disposed away from the base plate 610. The second free end 641 of the second cable-drawing rod 640 is disposed away from the base plate 610. The first recoil spring 650 is sleeved on the outer circumference of the first cable-drawing rod 630. The first recoil spring 650 is disposed between the first free end 631 and the base plate 610. The second recoil spring 660 is sleeved on the outer circumference of the second cable-drawing rod 640. The second recoil spring 660 is disposed between the second free end 641 and the base plate 610.

[0083] Specifically, the diameter of the first free end 631 is larger than the inner diameter of the first recoil spring 650, and the diameter of the first cable rod 630 is smaller than the inner diameter of the first recoil spring 650. The diameter of the second free end 641 is larger than the inner diameter of the second recoil spring 660, and the diameter of the second cable rod 640 is smaller than the inner diameter of the second recoil spring 660. The recoil spring ensures the holding force between the slide plate 620 and the base plate 610. At the same time, the reset between the slide plate 620 and the base plate 610 is also achieved.

[0084] like Figure 1 As shown, in one embodiment of the present application, the independent residential charging early warning cover further includes a circuit breaker 700. The circuit breaker 700 is arranged in the connection link of the socket 500. The fire sensor 200 is electrically connected to the circuit breaker 700.

[0085] Specifically, when the fire sensor 200 senses a fire in the charger of the electric bicycle connected to the electrical socket 500, the fire sensor 200 will provide an action level to the circuit breaker 700, and the circuit breaker 700 will cut off the circuit to prevent the current from being continuously converted into electric heat.

[0086] In one embodiment of the present application, the fire sensor 200 includes a smoke alarm, a temperature alarm or a visual smoke detector.

[0087] Specifically, the fire sensor 200 feeds back the fire situation, and the sprinkler 300 sprays the fire extinguishing agent.

[0088] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
