Detailed Description

The ejection device of the fire-fighting water battery rack of the present invention will be described and explained in detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the fire-fighting water battery rack comprises a rack body 1, a battery locking device 3, an ejection device 4, a battery plug-in component and battery supporting device 8 and a fire fighting water tank 7; the front part and the rear part of the frame body 1 are respectively provided with a plurality of layers of transverse supporting beams; the battery locking device 3 and the ejection device 4 are fixed on a transverse supporting beam at the rear part; battery strutting arrangement 8 vertically sets up on support body 1, and fire prevention basin 7 sets up on the downside ground of support body 1. The frame body 1 is assembled by C section bars and G section bars.

As shown in fig. 3, the ejector 4 includes a sleeve 41, a guide shaft 42, and a spring 43; the shaft sleeve 41 is a cylindrical structure with two open ends, wherein an opening at one end is provided with a mounting plate 44, and the mounting plate 44 is fixed on a transverse support beam at the rear part of the frame body 1 through bolts; the spring 43 is fitted around the guide shaft 41. The guide shaft 41 passes through the shaft sleeve 42, and one end of the guide shaft is provided with an ejection surface 45 with a larger area. The diameter of the ejection surface 45 is larger than the opening of the sleeve 42 to prevent the ejection surface from entering the sleeve and being stuck and unable to eject when the spring is compressed. The guide shaft 41 has a length smaller than that of the sleeve 42. The spring and guide shaft are received within the bushing 41 when the spring 43 is in a compressed state.

As shown in fig. 4, the battery card assembly includes a primary circuit card and a secondary card; the main movable plug-in unit 51 and the secondary plug-in unit male head 61 are fixed on a transverse support beam at the rear part of the frame body 1 and connected with the related battery serial-parallel connection lines and the system signal lines. The main circuit card 52 and the secondary card female head 62 are connected to the relevant wiring inside the battery 2. The main circuit static plug-in unit 52 and the secondary plug-in unit female head 61 are highly integrated on the battery 2 and are fixedly connected in advance, the main circuit movable plug-in unit 51 and the secondary plug-in unit male head 61 can be directly plugged into the female head on the battery after being connected with related circuits, plug and play are realized, the problem of wiring disorder is avoided, the whole wiring is more attractive, and the plug and play device can be directly pulled out during field maintenance, and is simple and convenient.

The battery locking device 3 comprises a locking block and a retaining ring; the locking block is fixed on a transverse supporting beam at the rear part of the frame body 1, and the lock catch is fixed on the battery 2. The inside of the locking block is provided with a connecting rod locking mechanism. The locking block is externally connected with a signal plug and connected with a control system, and electric control can be realized. The battery 2 is pushed from the other side of the locking block and is mechanically locked by a connecting rod locking mechanism clamped in the locking block through a lock catch.

In order to realize the technical effect of the utility model, the utility model discloses a water fire control formula battery holder is connected with control system, and control system is connected with battery locking device 3 for control battery locking device's unblock. Meanwhile, the control system is also used for monitoring the temperature of the battery. And when the temperature of the battery exceeds the safe temperature, alarming and sending an unlocking instruction to the battery locking device.

In normal operation, the battery 2 is placed on the battery support device 8, and the battery 2 is pushed to insert the male terminals of the main movable plug and the secondary plug into the female terminals of the main stationary plug and the secondary plug on the battery. At the same time, the lock block of the battery locking device 3 locks the lock catch, and the battery 2 is fixed at the working position. The ejection surface 45 of the ejector 4 is in contact with the battery and the spring 43 is under compression to store energy. When the control system detects that the battery is abnormal, the background sends a signal to drive the battery locking device 3 to act, the battery 2 is unlocked, the spring 43 recovers deformation, the battery 2 overcomes the friction force between the main circuit plug-in and the secondary plug-in under the action of the ejection device 4 and gravity, slides out of the normal working position by virtue of the roller on the supporting device 8, and falls into the fire water tank 7 arranged below, so that the battery 2 is completely immersed in water, and further accident diffusion is avoided.
