Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to an energy storage battery box. Background Art

[0002] With the rapid development of renewable energy construction, large-scale renewable energy is connected to the power grid. Lithium battery energy storage systems have been rapidly developed and widely used at home and abroad. As a key component, the quality of the battery box determines the overall comprehensive performance. At present, most energy storage battery boxes store energy by connecting batteries in series or in parallel to form battery packs. During long-term operation, energy storage batteries will generate heat to varying degrees, so heat dissipation is required. However, in the prior art, the heat dissipation performance of the energy storage battery box is poor and does not have a good heat dissipation function, which affects the heat dissipation of the energy storage battery box and even overheating, which is prone to safety hazards. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of the utility model is to provide an energy storage battery box with a simple structure and good heat dissipation effect.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An energy storage battery box comprises a battery box body, a battery compartment is installed at the lower end of the battery box body, and heat dissipation blocks are installed on both sides of the battery compartment; a plurality of fan installation openings are opened on one side wall of the battery box body, and a plurality of ventilation openings are opened on the other opposite side wall, so that air circulation can be ensured when the fan dissipates heat;

[0006] The outside of the battery box body is located at the position of the fan installation opening and is penetrated by the fan installation opening to install a fan. One end of each fan located inside the battery box body is fixedly connected with a conical opening, and the conical opening gradually becomes smaller from one end close to the fan to the other end;

[0007] An annular plate is provided at the connection between the fan and the battery box body, the annular plate is sleeved on the outside of the fan, and a plurality of side plates are fixedly connected to the side ends of the annular plate, each of which is provided with a through groove; a limiting mechanism is provided on the side plate, and the annular plate is fixed by the limiting mechanism so that the fan can be detachably installed on the battery box body; the limiting mechanism includes a hollow rod, one end of which is connected to the side wall of the battery box body, and the other end thereof penetrates the side plate;

[0008] A round rod is inserted into the inside of the hollow rod, and a spring is sleeved on the outside of the round rod; a round plate is arranged at one end of the round rod close to the battery box body, the round plate is rotatably arranged in the hollow rod, and the other end passes through the through-slot and is connected to a rotating plate matching the through-slot, and a pull plate is arranged at the other end of the rotating plate.

[0009] Through the above technical scheme, when the fan and the tapered mouth cooperate to perform cold air heat dissipation, when the fan blows air toward the large mouth of the tapered mouth, the air pressure at the small mouth of the tapered mouth increases and the temperature decreases. At this time, the wind blown out from the small tapered mouth is the cold air after cooling, which improves the heat dissipation effect; the heat dissipation block can quickly dissipate the heat of the batteries inside the battery compartment, and the heat dissipation block can also guide the heat of the batteries out of the vents; by rotating the pull plate, the directions of the rotating plate and the through-slot are made consistent, and the rotating plate is no longer limited and pressed against the side plate, thereby completing the disassembly of the fan, which is convenient for people to carry out maintenance.

[0010] Furthermore, a dustproof net is installed on the outer side wall of the battery box body near the ventilation hole to prevent dust.

[0011] Furthermore, a fan protection cover is provided at one end of each fan located outside the battery box body, which can protect the fan and prevent foreign objects from entering the fan and causing damage to the fan.

[0012] Furthermore, an anti-skid pad is fixed to the inner bottom end of the battery compartment, and the anti-skid pad has a certain anti-skid fixing effect when the battery is placed in the battery compartment.

[0013] Furthermore, the side panels are provided with two and are symmetrically arranged to complete the fixing of the fan.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The energy storage battery box, through the cooperation of the fan and the conical mouth, the fan blows air toward the large mouth of the conical mouth, at which time the air pressure at the small mouth of the conical mouth increases and the temperature decreases. At this time, the wind blown out from the small conical mouth is the cold wind after the temperature is reduced, and there is a certain temperature difference between the temperature of the wind directly blown by the fan. The cold wind blows toward the heat dissipation block to dissipate the heat of the battery compartment and the battery. The heat is conducted out of the vent through the heat dissipation block, thereby completing the heat dissipation of the battery inside the battery compartment. Compared with the traditional fan, the heat dissipation effect is improved;

[0016] (2) By rotating the pull plate, the directions of the rotating plate and the through slot are aligned. At this time, the rotating plate no longer limits the pressure on the side plate. At this time, the fan can be removed from the installation opening by pulling the fan, thereby completing the disassembly of the fan and facilitating maintenance;

[0017] (3) By setting up a fan protection cover and a dustproof net, not only can foreign objects be prevented from entering the fan and damaging the fan, but dust can also be prevented to prevent a large amount of dust from being brought into the battery box by the fan.

[0025] like Figure 1-4 As shown, the utility model provides an energy storage battery box, including a battery box body 1, a battery compartment 2 is installed at the lower end of the battery box body 1, an anti-skid pad 201 is fixed to the bottom end of the battery compartment 2, and the battery is placed in the battery compartment, and the anti-skid pad has a certain anti-skid fixing effect; heat dissipation blocks 202 are installed on both sides of the battery compartment 2; a plurality of fan installation openings 101 are opened on one side wall of the battery box body 1, and a plurality of ventilation openings 102 are opened on the other opposite side wall, so that air circulation can be ensured when the fan is dissipating heat; a dustproof net 103 is installed at the position of the ventilation opening 102 to prevent dust.

[0026] The outside of the battery box body 1 is located at the position of the fan installation opening 101, and a fan 3 is installed through the fan installation opening 101. Each fan 3 is fixedly connected to a conical opening 301 at one end located inside the battery box body 1, and the conical opening 301 gradually becomes smaller from one end close to the fan to the other end; each fan 3 is provided with a fan protection cover 4 at one end located outside the battery box body 1, which can protect the fan and prevent foreign matter from entering the fan and causing damage to the fan.

[0027] The connection between the fan 3 and the battery box body 1 is provided with an annular plate 302, which is sleeved on the outside of the fan 3, and the side ends of the annular plate 302 are fixedly connected to two symmetrically arranged side plates 303, each of which is provided with a through groove 304; a limiting mechanism is provided on the side plate 303, and the annular plate 302 is fixed by the limiting mechanism so that the fan can be detachably installed on the battery box body; the limiting mechanism includes a hollow rod 5, one end of the hollow rod 5 is connected to the side wall of the battery box body 1, and the other end passes through the side plate 303;
