[0028] In the above description of the utility model, it should be noted that the terms "one side", "the other side" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" and the like are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" and the like do not mean that the components are absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between the components is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0030] Please refer to Figs. 1-3 The utility model provides a technical scheme: water system zinc manganese battery performance test device, including installing in discharge box 1 end support frame 2, the end of discharge box 1 is rotationally cooperated with support frame 2, discharge box 1 and support frame 2 relative one side are provided with electromagnet 3 and permanent magnet 301 respectively, the opposite side polarity of electromagnet 3 and permanent magnet 301 is contrary, permanent magnet 301 is located on the rotation track of electromagnet 3.

[0031] In the scheme, the both ends of discharge box 1 are connected with support frame 2 through rotating shafts, because the top surface is provided with groove, the weight of the upper part of discharge box 1 is less than the weight of the lower part, which makes the side provided with groove rotate to downward in natural state.

[0032] The control circuit is connected in series with the power supply circuit of the electromagnet 3, and the control circuit is connected in series with the two discharge sheets 101.

[0033] In use, first, the operator rotates the discharge box 1 to make the side provided with groove upward, and places the battery in the groove so that the two ends of the battery are in contact with the two discharge sheets 101. At this time, the electromagnet 3 and the permanent magnet 301 are oppositely arranged, the battery releases residual electricity through the two discharge sheets 101, and part of the residual electricity is transmitted to the control circuit of the electromagnet 3 through the two discharge sheets 101, so that the control circuit transmits electricity to the power supply circuit to drive the electromagnet 3 to form a magnetic field. Then, because the polarity of the end of the electromagnet 3 close to the permanent magnet 301 is opposite, the electromagnet 3 is magnetically attracted to the permanent magnet 301 through the principle of magnetic pole heterogeneity after the electromagnet 3 forms a magnetic field, and the electromagnet 3 and the permanent magnet 301 are fixed through the magnetic attraction force, so that the discharge box 1 remains in the state that the groove faces upward.

[0034] When the battery runs out of power, the power supply circuit of the electromagnet 3 loses power, so that the magnetic field formed by the electromagnet 3 dissipates, thereby losing the magnetic attraction effect between the electromagnet 3 and the permanent magnet 301. Because the battery is placed in the groove on the upper part of the discharge box 1, the weight of the upper part of the discharge box 1 is greater than that of the lower part at this time, so that the discharge box 1 is turned over, the groove is turned over to face downward, and the centrifugal force generated during the turning over and the gravity of the battery itself cause the battery to fall out of the groove.

[0035] When the water-based zinc-manganese battery is discharged by using the water-based zinc-manganese battery performance test device, the electromagnet 3 is powered by the cooperation of the battery and the discharge sheet 101, so as to fix the discharge box 1 by the cooperation of the electromagnet 3 and the permanent magnet 301, when the battery is discharged, the electromagnet 3 loses the magnetic field, the discharge box 1 loses the fixing effect and is turned over, and the battery is thrown out by the centrifugal force generated by the turning over, so that the step of taking out the battery in the discharge test by the operator is reduced, the safety hidden danger generated by the operator contacting the battery in the discharge test is reduced, and part of the labor consumption of the operator is reduced.

[0036] In the embodiment, the bottom surface of the support frame 2 is provided with a collection box 4, the collection box 4 is provided with a through port 401 communicating with the inside of the collection box 4, and the through port 401 is located on the rotation track of the groove.

[0037] In specific use, when the discharge box 1 is turned over, the battery is turned over by 70°-110°, at this time, the centrifugal force generated by the rotation is the largest because the battery is downward, so that the battery is affected by the centrifugal force and separated from the groove, and enters the collection box 4 through the through port 401 to be collected uniformly.

[0038] In the embodiment, one side of the groove is provided with an open port, the open port is provided with a rotating plate, both ends of the rotating plate are rotationally matched with the open port, and the lower part of the rotating plate is located in the groove.

[0039] In the embodiment, the rotating plate comprises a vertical plate 5 rotationally matched with the side wall of the groove at both ends and a horizontal plate 501 vertically connected with the bottom surface of the vertical plate 5, and the top surface of the horizontal plate 501 is flush with the bottom surface of the groove.

[0040] When the operator puts the battery into the groove, the horizontal plate 501 is located below the battery, the top surface of the horizontal plate 501 is in contact with the bottom surface of the battery, at this time, the bottom surface of the horizontal plate 501 is in abutment with the groove, so that the vertical plate 5 cannot be rotated towards the direction where the groove is located and can be rotated away from the direction where the groove is located, and the vertical plate 5 is not easy to rotate in a natural state under the pressure of the battery on the horizontal plate 501.

[0041] In specific use, when the discharge box 1 is turned over, the battery and the vertical plate 5 are affected by the centrifugal force, the battery is pushed out of the groove under the centrifugal force, at this time, the pressure of the battery on the horizontal plate 501 is reduced, the vertical plate 5 is rotated under the centrifugal force, and the battery is pushed out by the horizontal plate 501.

[0042] In the embodiment, one side of the discharge box 1 away from the rotating plate is provided with an accommodating groove extending along the thickness direction of the discharge box 1, and the accommodating groove is provided with a counterweight 6.

[0043] The counterweight 6 is installed on the side of the discharge box 1 away from the rotating plate, so that when the discharge box 1 is overturned due to the loss of the permanent magnet 301 and the electromagnet 3, the discharge box 1 will always rotate towards the side where the counterweight 6 is installed. At the same time, the setting of the counterweight 6 effectively increases the centrifugal force on the battery and the vertical plate 5 when the discharge box 1 is overturned.

[0044] In this embodiment, the top surface of the collection box 4 is provided with a baffle 7, which is located on the rotating track of the side of the vertical plate 5 facing the groove.

[0045] In this embodiment, the top surface of the collection box 4 is provided with a baffle 7, which is located on the rotating track of the side of the vertical plate 5 facing the groove.

[0046] In actual use, when the discharge box 1 is overturned and rotated to 70°, the side of the vertical plate 5 facing the groove collides with the baffle 7, and the vertical plate 5 is rotated and drives the horizontal plate 501 to push the battery out due to the impact force generated by the two.

[0047] In this embodiment, the baffle 7 is located on one side of the through hole 401, and a guide plate opposite to the baffle 7 is arranged on the other side of the through hole 401.

[0048] In this embodiment, the baffle 7 is located on one side of the through hole 401, and a guide plate opposite to the baffle 7 is arranged on the other side of the through hole 401.

[0049] In this embodiment, the guide plate and the baffle 7 are oppositely and obliquely installed, the distance between the upper ends of the guide plate and the baffle 7 is greater than the distance between the lower ends of the guide plate and the baffle 7, and the lower ends of the guide plate and the baffle 7 are located on the two sides of the through hole 401, respectively.

[0050] In this embodiment, the guide plate and the baffle 7 are obliquely installed, and the cross sections of the guide plate and the baffle 7 are funnel-shaped structures, which can collect the batteries in a larger range and are not easy to cause the batteries to be thrown out before they are rotated to face the collection box 4, resulting in the phenomenon of being separated from the through hole 401.

[0051] In this embodiment, a sliding groove is formed in one side of the outer wall of the collection box 4 and communicates with the inside of the collection box 4, a basin body 8 is slidably connected in the sliding groove, and a sliding block and a dovetail groove are arranged on the opposite sides of the basin body 8 and the opposite sides of the sliding groove, respectively.

[0052] In actual use, the batteries falling into the collection box 4 through the through hole 401 fall onto the basin body 8, and the operator can pull out the basin body 8 to collect the batteries in the collection box 4 by pulling one end of the basin body 8 outside the collection box 4, thereby reducing the steps of taking out the batteries one by one and reducing the labor consumption of the operator.

[0053] In the embodiment, one side of the support frame 2 is provided with a rotating disc 9 coaxially rotating with the discharge box 1 and a bell 10, the rotating disc 9 is connected with the discharge box 1, the arc surface of the rotating disc 9 is provided with a protrusion 901 extending along the diameter length of the rotating disc 9, and the bell 10 is installed below the rotating disc 9 and located on the rotating track of the protrusion 901.

[0054] When the discharge box 1 is in the concave groove direction, the protrusion 901 on the rotating disc 9 is also upward;

[0055] In specific use, when the discharge box 1 is overturned, the rotating disc 9 connected with the discharge box 1 is synchronously rotated, the protrusion 901 is rotated toward the direction where the bell 10 is located under the driving of the rotating disc 9, when the discharge box 1 is overturned by 70°, the impact force generated by the rotation promotes the protrusion 901 to collide with the bell 10, and the bell 10 emits a sound to remind the operator that the battery is discharged.

[0056] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and all of them should be covered in the claim range of the utility model.
