Description

Waterproof emergency power supply

Technical Field

Background

At present, urban buildings in China develop rapidly, and large public buildings are more and more. The buildings have complex internal structures and high personnel density, and in case of fire, due to the lack of escape training and evacuation experience, when a plurality of escape paths are met, such as improper evacuation guidance and command, people and personnel usually take familiar paths or choose paths through which more people pass, so as to present a mass-oriented behavior pattern. Most of the casualties are caused by the poison of smoke on the fire scene because the escape direction can not be determined.

Therefore, the current national fire protection code of architectural design strictly regulates the setting of fire detection alarm systems and evacuation instructions. The personnel evacuation safety is not only related to the fire position and the spreading direction, but also related to the evacuation route and the action state of related evacuation facilities. The intelligent evacuation indicating system improves the traditional concept of evacuation in the near fixed direction into an active and reasonable evacuation concept of keeping away from a fire, so that the evacuation indication, the fire condition and the evacuation facility action condition are cooperatively linked. Compared with the traditional evacuation indicating system, the system has huge technical advantages and practical value, and has very important significance for changing the current situation of fire safety evacuation. The emergency power supply is a novel emergency power supply system which mainly aims at solving the problems of emergency lighting, fire-fighting facility lighting and reliable load power supply, is suitable for occasions where the fire-fighting lighting power supply or the generator set is replaced to form a second power supply to provide a standby power supply for other fire-fighting power facilities, and makes a great contribution to power supply of rear-end equipment.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The present invention provides a waterproof emergency power supply, referring to fig. 1 and 2, comprising: the box comprises a box body 1, a box door 2, a door seam waterproof unit 3 and a waterproof joint 4.

The improvement of the emergency power supply structure mainly comprises two aspects, wherein the first aspect is to additionally install a door seam waterproof unit; the second aspect is to adopt the water joint to improve emergency power's waterproof performance comprehensively. These two aspects are described in detail below:

waterproof unit for door gap (I) 3

One side of the box body 1 is hinged with a mounting box door 2; referring to fig. 3, the box body 1 is provided with a box frame 1-1, planar folding edges extend outwards from the periphery of the inner wall of the box frame 1-1, and each planar folding edge is enclosed into a rectangular frame body 1-2; each plane folded edge extends outwards to form an outward-expanded inclined folded edge, and each inclined folded edge encloses an outward-expanded water-blocking frame body 1-3;

referring to fig. 4, a door frame body 2-1 is arranged around the inner wall of the box door 2, the door frame body 2-1 is rectangular, and when the box door 2 rotates to a closed state, the door frame body 2-1 of the box door 2 is tightly buckled outside the rectangular frame body 1-2 of the box body 1; as a specific embodiment, a rubber sealing ring 5 may be installed between the box body 1 and the box door 2 to further improve the waterproof performance.

Therefore, if a door gap is formed between the door frame body 2-1 of the box door 2 and the box body 1, when water flows into the box body 1 from the door gap, the water firstly contacts with the rectangular frame body 1-2 of the box body 1 through the door gap, and due to the blocking effect of the outward-expanded water blocking frame body 1-3, the water can flow downwards along the rectangular frame body 1-2 and finally flows out from the lower part of the rectangular frame body 1-2, so that the water diversion effect is realized through the effects of the rectangular frame body 1-2 and the outward-expanded water blocking frame body 1-3, the water is prevented from flowing into the box body 1 to damage related devices, and the waterproof effect is achieved.

(II) waterproof joint 4

Because emergency power source need install a plurality of joints, power supply cable or communication cable need pass the joint, and one end is connected with the electrical part in the box, and the other end and outside consumer interface connection, consequently, in the practical application, there is the clearance usually between joint and the cable, and inside the box that leads to water to flow in through the clearance of joint and cable, brought the power consumption safety problem. In order to solve the problems, the utility model also improves the connector, adopts a specially designed waterproof connector to make the connector closely contact with the cable, and realizes the waterproof effect.

The box body 1 is provided with a waterproof joint 4, and referring to fig. 5-6, the waterproof joint 4 comprises a nut 4-1, a nut 4-2, a packing head 4-3, a clamping sealing ring 4-4 and a joint body 4-5; the box body 1 is provided with a through hole at the position where the waterproof joint 4 needs to be installed; the screw cap 4-1 is welded on the inner wall of the box body 1 and is communicated with the through hole; one end of the joint body 4-5 is an external thread part A, and the other end is a conical elastic part B; the external thread part A of the joint body 4-5 passes through the through hole and is in threaded connection with the nut 4-1; the nut 4-2 is in threaded connection with the external thread part A of the joint body 4-5 and is screwed on the outer wall of the box body 1, and the joint body 4-5 is hermetically arranged on the box wall of the box body 1 under the action of the nut 4-1 and the nut 4-2; a clamping seal ring 4-4 is embedded and mounted in the conical elastic part B of the joint body 4-5; the packing head 4-3 is sleeved outside the conical elastic part B, and one end of the packing head 4-3 is in threaded connection with the external thread part A.

As a specific implementation manner, the conical elastic part B is a conical structure surrounded by a plurality of rectangular teeth. The clamping seal ring 4-4 is a conical structure matched with the shape of the conical elastic part B.

The waterproof principle of the waterproof joint is as follows:

one end of a cable (including various cables such as a power supply cable and a communication cable) is electrically connected with related devices in the box body, and the other end of the cable penetrates through the clamping sealing ring 4-4 in the connector body 4-5 to extend to the outside and is connected with electric equipment.

When the cable passes through the clamping seal ring 4-4, the clamping seal ring 4-4 is deformed, and the outer diameter is increased; when the outer diameter of the clamping seal ring 4-4 is increased, the conical elastic part B of the joint body 4-5 is deformed, and the outer diameter is increased; when the outer diameter of the conical elastic part B is increased, clamping force in the opposite direction is applied to the conical elastic part B due to the limiting effect of the packing head 4-3, so that the conical elastic part B firmly clamps the cable through the clamping sealing ring 4-4, and firm clamping force among the cable, the clamping sealing ring 4-4, the conical elastic part B and the packing head 4-3 is realized, therefore, any two contact parts of the cable, the clamping sealing ring 4-4, the conical elastic part B and the packing head 4-3 are in close contact, and the waterproof effect is realized.

In addition, as for the waterproof connector 4 and the box body 1, the nut 4-1 and the nut 4-2 are respectively positioned at two sides of the box body 1 and are in threaded connection with the external thread part A of the waterproof connector 4, therefore, the waterproof sealing is realized between the nut 4-1 and the nut 4-2 and the box body 1, the waterproof sealing is realized between the nut 4-1 and the nut 4-2 and the external thread part A, and further the waterproof sealing is realized between the waterproof connector 4 and the box body 1.
