[0024] 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 in 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.

[0025] The utility model provides a technical solution:

[0026] See also Figures 1 to 5A device for monitoring the power state of an energy storage battery comprises a bracket 1, wherein a transposition component 2 is provided inside and on the upper side of the bracket 1, wherein the transposition component 2 comprises two guide grooves 21 provided on the upper side of the bracket 1, wherein the two guide grooves 21 are both wavy in shape, the two guide grooves 21 are cross-arranged and the intersection of the two guide grooves 21 is connected; the four ends of the two guide grooves 21 are fixedly connected with fixed snap rings 22, and the corners of the two guide grooves 21 are rotatably connected with movable snap rings 23, wherein the insides of the two fixed snap rings 22 are pressed and contacted with two moving detection heads 24, and two adjacent detection heads 24 are slidably connected in the same guide groove 21, and one side of the opposite surface of the two adjacent detection heads 24 is fixedly connected with a first reset spring 25, and the outer sides of the two adjacent detection heads 24 are sleeved with the same connecting plate 26, and the upper side of the connecting plate 26 is fixedly connected with a connecting wire 27, and the two connecting wires 27 are connected with a measuring meter 28. The measuring meter 28 is set as a voltmeter, and the remaining power is judged by measuring the voltage, so that the power state of the battery can be monitored.

[0027] A pressing assembly 29 is commonly provided on the upper sides of the two detection heads 24 .

[0028] The entrances of the fixed snap ring 22 and the movable snap ring 23 are both provided with two inclined surfaces, and the outer side of the detection head 24 is provided with two inclined surfaces. The inclined surfaces of the detection head 24 are in sliding contact with the inclined surfaces of the fixed snap ring 22 and the movable snap ring 23 .

[0029] By adopting the above technical solution, first, the bracket 1 is placed above a group of energy storage batteries to be monitored. At this time, the electrodes of the multiple energy storage batteries will be respectively at the corners and ends of the guide groove 21, and the two detection heads 24 inside the guide groove 21 will be connected to the measuring meter 28 through the connecting line 27. By squeezing the two pressing plates 293, the two pressing plates 293 are moved closer to the middle, which will also drive the two detection heads 24 to move closer to the middle. At this time, the upper sides of the two detection heads 24 will slide on the outside of the guide rod 292 in the moving groove 291 inside the connecting plate 26, and the connecting plate 26 is always above the bracket 1. After releasing the pressing plate 293, The second return spring 294 pushes the two pressing plates 293 to move to both sides. When the two detection heads 24 are pushed into the end of the guide groove 21 at the front, the inclined surface of the detection head 24 will contact the inclined surface of the fixed clamp ring 22, and then the two detection heads 24 will be squeezed. When the two detection heads 24 completely enter the fixed clamp ring 22, the first return spring 25 between the two detection heads 24 will push the two detection heads 24, so that the detection heads 24 and the fixed clamp ring 22 are tightly fitted. At the same time, the two detection heads 24 will also be outside the electrodes of the energy storage battery. After the two electrodes are clamped, the energy storage battery can be tested by the measuring meter 28;

[0030] When it is necessary to monitor the next energy storage battery, the two detection heads 24 can be pushed through the connecting plate 26, and the two detection heads 24 on the left side slide to the right through the guide groove 21 and enter the movable clamping ring 23 at the corner of the guide groove 21, and finally clamp the corresponding electrodes of the energy storage battery, while the two detection heads 24 on the right side will slide to the left, so that the corresponding two detection heads 24 are clamped on the outside of the same electrode each time. Since the detection heads 24 are always in the guide groove 21 and move to the electrode of the next energy storage battery through the guide groove 21, and the electrode clamped each time is the same as the electrode of the previous energy storage battery, repeated disassembly of the detection heads 24 is avoided, and the monitoring efficiency of the measuring meter 28 on the power status of the energy storage battery is guaranteed.

[0031] Specifically, Figure 4 As shown, the pressing assembly 29 includes a moving groove 291 opened on the surface of the connecting plate 26 , and the insides of the two moving grooves 291 are fixedly connected with guide rods 292 , and the two detection heads 24 are respectively sleeved on the outsides of the two guide rods 292 .

[0032] The two detection heads 24 are slidably connected in the two moving grooves 291 , respectively. A pressing plate 293 is fixedly connected to the upper sides of the two detection heads 24 , and the opposite surfaces of the two pressing plates 293 are fixedly connected to the same second return spring 294 .

[0033] A steering component 3 is provided inside the bracket 1, and the steering component 3 includes a fixed plate 31 fixedly connected to the outside of the movable clamping ring 23. Four rotation grooves 33 are opened on the surface of the bracket 1. The two rotation grooves 33 are respectively connected to the two guide grooves 21. The four fixed plates 31 are respectively slidably connected in the four rotation grooves 33.

[0034] Limit rods 32 are fixedly connected to the upper and lower sides of the fixed plate 31 . Arc grooves 34 are formed on the inner upper side and the inner lower side of the rotating groove 33 . The two limit rods 32 are slidably connected in the two arc grooves 34 .

[0035] Two mounting plates 4 are fixedly connected to the front and back of the bracket 1 , and locking bolts 5 are connected to the inner threads of the mounting plates 4 .

[0036] By adopting the above technical solution, first, after the detection head 24 completes monitoring of the energy storage battery at the corner of the guide groove 21, since the width of the movable snap ring 23 is smaller than the fixed snap ring 22, when the movable snap ring 23 is pushed, the fixed plate 31 on the outside of the movable snap ring 23 will be inside the movable groove 291, and the limit rods 32 on the upper and lower sides of the fixed plate 31 will slide in the two arc grooves 34 respectively, so that the opening direction of the movable snap ring 23 will change. At this time, the movable snap ring 23 will not be blocked by the energy storage battery electrode. When the opening of the movable snap ring 23 is facing When reaching the corner of the next guide groove 21, the two detection heads 24 can be pushed through the guide groove 21 to the inside of the movable retaining ring 23 at the next corner. Before detecting the energy storage electrode, the mounting plates 4 on both sides are supported to contact the side of the energy storage battery, and then the bolts are tightened to fix the bracket 1 on the outside of the energy storage battery. Since the movable retaining ring 23 can rotate freely, it is convenient to guide the two clamping plates to reach the electrode of the next energy storage electrode, and the two detection heads 24 do not need to be taken out during the movement, which further improves the detection efficiency of the measuring meter 28 for the energy storage battery.

[0037] Working principle: First, place the bracket 1 on the outside of the energy storage battery through the mounting plate 4 and lock it with bolts. The two detection heads 24 will be connected to the measuring meter 28 through the connecting line 27. After squeezing the two pressing plates 293, the two pressing plates 293 will drive the two detection heads 24 to move closer to the middle, so that the upper side of the detection head 24 will slide on the outside of the guide rod 292 in the movable groove 291 inside the connecting plate 26. After releasing the pressing plate 293, the second return spring 294 pushes the two pressing plates 293 to move to both sides. When the two detection heads 24 are pushed into the end of the guide groove 21 located in the front, the detection heads 24 will be stuck in the fixed clamping ring 22 and clamp the electrodes of the energy storage battery. The first return spring 25 between the two detection heads 24 will push the two detection heads 24 so that the detection heads 24 are tightly fitted with the fixed clamping ring 22. After the two electrodes are clamped, the energy storage battery can be detected by the measuring meter 28.

[0038] When it is necessary to monitor the next energy storage battery, two of the detection heads 24 slide to the right through the guide groove 21 and enter the inside of the movable snap ring 23 at the corner of the guide groove 21, while the two detection heads 24 on the right will slide to the left, so that the corresponding two detection heads 24 are clamped on the outside of the same electrode each time. After the detection heads 24 have completed monitoring the energy storage battery at the corner of the guide groove 21, they can push the movable snap ring 23, so that the fixed plate 31 on the outside of the movable snap ring 23 will be inside the movable groove 291, and the limit rods 32 on the upper and lower sides of the fixed plate 31 will slide in the two arc grooves 34 respectively, causing the opening direction of the movable snap ring 23 to change. When the opening of the movable snap ring 23 faces the corner of the next guide groove 21, the two detection heads 24 can be pushed through the guide groove 21 to the inside of the movable snap ring 23 at the next corner.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
