Abstract
Description
Technical Field
[0001] The utility model relates to a monitoring device, in particular to a charging pile fire monitoring device, and belongs to the technical field of new energy vehicle energy replenishment facilities. Background Art
[0002] The fire hazard of new energy vehicles during the charging process has always been a high-profile issue in the society, and fires during the charging process also occur from time to time. In addition, due to the long charging time, many car owners choose to leave their vehicles during the charging process, especially late at night, and the entire charging station is often unattended, which further highlights the importance of fire monitoring.
[0003] There are usually two types of fires. One is that the fire comes from the vehicle until the fire spreads to the charging pile through the charging cable; the other is that the fire comes from the charging pile and spreads to the vehicle. The existing charging column monitoring system mainly monitors the short circuit of the circuit and cuts off the power supply in time to prevent the spread of the fire. However, since the charging column and the vehicle are almost two independent systems, once the fire comes from the vehicle, it is difficult for the charging pile to monitor it. In this case, there is a possibility that the fire will spread to the charging pile, which also frequently occurs in actual application scenarios, posing a great hidden danger. However, due to reasons such as vehicle condition, quality, and cost, the technical level of vehicles varies, so it is difficult to require all vehicles to have the ability to promptly judge the occurrence of a fire. Therefore, it is necessary to design a monitoring device that can promptly judge whether a fire has occurred during the charging process, and can operate independently without relying on the vehicle or charging pile system. Utility Model Content
[0004] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a charging pile fire monitoring device, which can independently judge the fire situation without being restricted by the vehicle condition, has an efficient and accurate judgment method, a simple and reasonable structure, and strong applicability.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A charging pile fire monitoring device includes a pile body arranged in each parking space, a protective cover is arranged on the surface of the pile body; a photoelectric receiving element is arranged on the protective cover; a sliding component is arranged on the parking space; a photoelectric emitting element is arranged on the sliding component; and a contact detection element is arranged in the sliding component.
[0007] Furthermore, the photoelectric receiving element is an infrared receiving grating; the infrared receiving grating is arranged on the side of the protective cover facing the ground; and the photoelectric emitting element is an infrared emitter.
[0008] Furthermore, a guide groove is provided on one side of the parking space close to the pile body; the sliding assembly includes a slider; the slider is slidably connected in the guide groove; the infrared transmitter is arranged on the surface of the slider; and the infrared transmitter is arranged opposite to the infrared receiving grating.
[0009] Furthermore, a return spring is arranged between the slider and the guide groove; the contact detection element includes a contact sensor arranged inside the guide groove; a contact is arranged on the side of the slider opposite to the contact sensor; the spring includes two; and the contact and the contact sensor are arranged between the two springs.

[0012] Furthermore, the flexible inner layer is a sponge or a rubber filler; and the flexible surface layer is a fabric or a rubber surface layer.
[0013] The utility model has the following beneficial effects: it can be adapted to most existing charging stations, and form an infrared radiation effect through photoelectric emitting elements and photoelectric receiving elements. When a fire occurs and thick smoke is produced, interference will be formed between the infrared radiations, blocking the infrared radiation state; when the controller determines that the photoelectric receiving element stops receiving and continues for a period of time, an alarm can be issued in time.
[0014] At the same time, the layout positions of the photoelectric emitting elements and the photoelectric receiving elements cover a wide range, being located between the vehicle and the charging pile, thus maximally covering the paths through which smoke may pass; and they can be adaptively adjusted according to different vehicle sizes, and the infrared radiation state will not be blocked by the vehicle.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The terms used herein, including technical and scientific terms, have the same meaning as those generally understood by those skilled in the art, unless the terms are defined differently. It should be understood that the terms defined in commonly used dictionaries have the same meaning as those in the prior art.
[0022] See also Figure 1-Figure 3
[0023] A charging pile fire monitoring device includes a pile body 1 arranged in each parking space, a protective cover 2 is arranged on the surface of the pile body; a photoelectric receiving element is arranged on the protective cover 2; a sliding component is arranged on the parking space; a photoelectric emitting element is arranged on the sliding component; and a contact detection element is arranged in the sliding component.
[0024] Furthermore, the photoelectric receiving element is an infrared receiving grating 3 ; the infrared receiving grating 3 is arranged on the side of the protective cover 2 facing the ground; and the photoelectric emitting element is an infrared emitter 4 .
[0025] Furthermore, a guide groove 5 is provided on one side of the parking space close to the pile body 1; the sliding assembly includes a slider 6; the slider 6 is slidably connected in the guide groove 5; the infrared transmitter 4 is arranged on the surface of the slider 6; the infrared transmitter 5 is arranged opposite to the infrared receiving grating 3.
[0026] In this embodiment, within the travel range of the slider 6, the infrared emitter 5 can directly emit light to the infrared receiving grating 3; the infrared emitter 5 forms a light-emitting relationship with any point of the infrared receiving grating 3, and forms a light-emitting band. Once smoke is generated, it will cause interference in the light-emitting band and block the formation of the light-emitting band.
[0027] Furthermore, a return spring 7 is arranged between the slider 6 and the guide groove; the contact detection element includes a contact sensor 8 arranged inside the guide groove 5; a contact 9 is arranged on the side of the slider 6 opposite to the contact sensor 8; the spring 7 includes two; the contact and the contact sensor are arranged between the two springs 7.
[0028] Specifically, when the vehicle enters the parking space, it will push the slider 6 to move, and finally the contact 9 on the slider 6 will contact the contact sensor 8, indicating that the vehicle has been parked in place. Since the vehicle pushes the slider 6 to move, the shooting point of the infrared transmitter 5 to the infrared receiving grating 3 will change, but the shooting zone is still formed. Due to different vehicle models, some vehicles have longer tails, which can easily block the infrared transmitter 5. However, the design of this embodiment can allow the infrared transmitter 5 to move with the displacement of the vehicle end, and the infrared transmitter 5 is always in a shooting state with the grating and will not be blocked by the vehicle.
[0029] Furthermore, the sliding assembly further comprises two columns 11 arranged on the surface of the sliding block 6 ; a supporting column 12 is arranged between the two columns 11 .
[0030] Furthermore, the abutment column 12 is in contact with or separated from the rear of the vehicle; the abutment column 12 has a flexible surface layer and an inner layer.
[0031] Furthermore, the flexible inner layer is a sponge or a rubber filler; and the flexible surface layer is a fabric or a rubber surface layer.
[0032] Specifically, the abutment column 12 is in direct contact with the vehicle, and the movement of the abutment column 12 drives the movement of the slider 6, and then drives the movement of the infrared emitter 5; therefore, the abutment column 12 is soft in texture and will not bump against the vehicle during the contact process.
[0033] When the vehicle enters, since the guide groove 5 is located between the two rear wheels or the front wheels of the vehicle, the front end or the rear end of the vehicle will directly contact the abutment column 12 .
[0034] Furthermore, the photoelectric receiving element is connected to a controller; and the controller is connected to an alarm.
[0035] When the photoelectric receiving element determines that the infrared radiation disappears, it will feedback to the controller, and the controller will feedback the fire situation to the alarm.
[0036] Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the utility model rather than limiting it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
