[0052] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0053] In the prior art, in the DC system of a substation, a battery pack is placed in a cabinet as a backup device to be used as a power supply for the substation in an accident state. In order to ensure the normal use of the battery pack in the substation accident state, it is usually necessary to perform a test piece inspection on the battery pack. The existing test device includes a test head, and the test head is manually connected to the battery pole during the test. When the batteries in the cabinet are displayed in two rows, inner and outer, the arm needs to go deeper into the cabinet during the test to connect the test head to the pole of the battery in the inner row. The above-mentioned method of connecting the test head to the battery pole poses a risk of electric shock to personnel.
[0054] In order to overcome the defects in the prior art, the present application provides a battery testing device, including at least one testing assembly, the testing assembly including an operating rod, a testing head and a protective tube; the testing head is arranged at one end of the operating rod, the protective tube is provided with a receiving through hole, the operating rod is passed through the receiving through hole; the operating rod moves along the axial direction of the receiving through hole, so that the testing head extends out or is received in the receiving through hole; after the testing head extends out of the receiving through hole, the testing head is operated to connect to the pole of the battery. This application is used to solve the problem of electric shock caused by the arm extending into the cabinet.
[0055] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.
[0056] Figure 1 A schematic diagram of a battery testing device provided in an embodiment of the present application.
[0057] See also Figure 1 As shown, a battery testing device provided by the present application includes at least one testing assembly 100 , and the testing assembly 100 includes an operating rod 110 , a testing head 120 and a protective tube 130 .
[0058] The test head 120 is disposed at one end of the operating rod 110 . The protection tube 130 is provided with a receiving through hole 131 . The operating rod 110 passes through the receiving through hole 131 .
[0059] The operating rod 110 moves along the axial direction of the receiving through hole 131 to make the test head 120 extend out of or retract into the receiving through hole 131 .
[0060] After the test head 120 extends out of the receiving through hole 131 , the operating rod 110 is manipulated to connect the test head 120 to the battery terminal.
[0061] Illustratively, the number of the test components 100 may be one or more, which is not limited herein.
[0062] Exemplarily, the protection tube 130 is a cylindrical tube, and the receiving through hole 131 is arranged along the axial direction of the protection tube 130 .
[0063] It should be noted that a test head 120 is provided at one end of the operating rod 110, and the other end serves as a gripping end, which is maintained at one end extending out of the receiving through hole 131, so as to be gripped by an operator; the operator grips the gripping end to control the axial movement of the operating rod 110 along the receiving through hole 131, and the test head 120 follows the movement of the operating rod 110; therefore, when the battery needs to be tested, one end of the test line is connected to the test head 120, and the other end is connected to a test instrument; at this time, the test head 120 is received in the receiving through hole 131, and the test head 120 is extended into the cabinet together with the protective tube 130 by operating the operating rod 110; In particular, when the battery to be tested is located in the inner row, the test head 120 passes through the outer row of batteries until it reaches the pole position of the battery to be tested in the inner row. At this time, the operating rod 110 is operated to push the test head 120 out of the receiving hole 131, and the test head 120 is brought into contact with the pole of the battery to be tested. The operator tests the internal resistance and other data of the battery through the test instrument. On the contrary, when the test is completed, the test instrument and the test line are removed first, and then the operating rod 110 is operated to pull the test head 120 back into the receiving hole 131, and finally the operating rod 110, the test head 120 and the protective tube 130 are taken out of the cabinet together.
[0064] In this way, the present embodiment sets an operating rod 110, and the test head 120 is set at one end of the operating rod. The test head 120 is extended into the cabinet through the operating rod 110, so as to connect the test head 120 with the pole of the battery in the cabinet, thereby avoiding the risk of electric shock caused by extending the arm into the cabinet. At the same time, the above-mentioned protective tube 130 provides a storage hole 131 for the test head 120 during the process of the test head 120 extending into or out of the cabinet. During this process, the test head 120 is stored in the storage hole 131, which effectively avoids the collision between the test head 120 and other components in the cabinet, and prevents equipment damage caused by the collision; in addition, the test head 120 that has completed the test and exited the cabinet can be stored in the storage hole 131 all the time, which improves the safety of the storage of the test head 120.
[0065] In some embodiments, the test assembly 100 further includes a cover 140 .
[0066] When the test head 120 is received in the receiving through hole 131 , the cover 140 covers one end of the receiving through hole 131 close to the test head 120 .
[0067] And / or, the test assembly further includes a connecting rope 150;
[0068] One end of the connecting rope 150 is connected to the sealing cover 140 , and the other end is connected to the protection tube 130 .
[0069] Exemplarily, the cover 140 may be made of plastic or metal, which is not limited herein.
[0070] It can be known that the cover 140 is removed and put away before the test head 120 is inserted into the cabinet, and the cover 140 is covered after the test head 120 is pulled into the receiving hole 131 and withdrawn from the cabinet; in this way, the cover 140 effectively closes the end of the receiving hole 131 to protect the test head 120 in the receiving hole 131.
[0071] In addition, the sealing cover 140 and the protection tube 130 are connected by threads, so as to improve the connection reliability between the two.
[0072] Exemplarily, the connecting rope 150 may be a wear-resistant rope.
[0073] It can be known that after the cover 140 is removed from one end of the receiving through hole 131 , the connecting rope 150 can keep the cover 140 hanging on the protective tube 130 to avoid the cover 140 from being lost.
[0074] In some embodiments, the test head 120 includes a main rod 121 and a clamping rod 122 .
[0075] One end of the main rod 121 is connected to one end of the operating rod 110, and the other end of the main rod 121 forms a first clamping end; one end of the clamping rod 122 is connected to one side of the main rod 121, and the other end extends away from the operating rod 110 to form a second clamping end.
[0076] In the axial direction of the operating rod 110 , after the clamping rod 122 is opened, the second clamping end is flush with the first clamping end, and a clamping position is formed between the second clamping end and the first clamping end.
[0077] The clamping position is used to clamp onto the battery pole to achieve electrical connection between the test head 120 and the battery pole.
[0078] Exemplarily, the main rod 121 and the clamping rod 122 are both made of conductive metal.
[0079] It should be noted that a clamping position is formed between the first clamping end and the second clamping end. The clamping position is clamped on one end of the battery pole by operating the operating lever 110. The clamping of the clamping position makes the connection between the test head 120 and the pole more reliable, avoiding problems such as test errors caused by poor contact between the test head 120 and the pole during the test process.
[0080] In some embodiments, the test head 120 further includes a first tension member 123 .
[0081] One end of the clamping rod 122 is rotatably disposed on the main rod 121 , one end of the first stretching member 123 is connected to the main rod 121 , and the other end is connected to the clamping rod 122 .
[0082] When the clamping rod 122 is received in the receiving through hole 131 , the clamping rod 122 is squeezed by the inner wall of the receiving through hole 131 and rotates toward the main rod 121 to compress the first tensioning member 123 .
[0083] Exemplarily, the first tensioning member 123 is a spring; in other embodiments, the first tensioning member 123 may also be a spring, which will not be listed here one by one.
[0084] Exemplarily, one end of the clamping rod 122 is hinged to the main rod 121 .
[0085] It should be noted that when the clamp rod 122 is received in the receiving hole 131, the clamp rod 122 is squeezed by the inner wall of the receiving hole 131 and rotates toward the main rod 121 to compress the first tensile member 123. It can be understood that when the clamp rod 122 is in the receiving hole 131, it tilts toward the main rod 121. The significance of this is that at this time, the radial width of the test head 120 in the receiving hole 131 is reduced. From this, it can be known that, in terms of design requirements, the diameter of the receiving hole 131 can be reduced accordingly, and then the outer diameter of the protective tube 130 is also reduced accordingly. The smaller the diameter of the protective tube 130 is, the smaller the probability of the protective tube 130 colliding with the surrounding batteries and the impact on the line of sight when the operating rod 110 is extended into the cabinet for battery testing. In addition, when the clamp rod 122 is extended to the receiving hole 131, the outer diameter of the protective tube 130 is reduced accordingly. After the through hole 131 is inserted out, the first stretching member 123 is extended, and the clamping rod 122 rotates in the direction away from the main rod 121. After the second clamping end is flush with the first clamping end, a clamping position is formed between the two. The test head 120 is clamped on the pole through the clamping position. The clamping improves the stability of the connection between the test head 120 and the pole. In addition, the second clamping end and the first clamping end form two contact points with the pole, which increases the contact area between the test head 120 and the pole and ensures the reliability of the contact between the test head 120 and the pole.
[0086] In some embodiments, test head 120 further includes an opening lever 124 .
[0087] One end of the opening rod 124 is connected to one side of the main rod 121 , and the other end is extended in a direction away from the operating rod 110 to form an opening end.
[0088] In the direction of the axis of the operating rod 110 away from the main rod 121, the opening end protrudes beyond the first clamping end.
[0089] When the operating rod 110 is operated to approach the battery pole, the opening end first abuts against the cap on the battery pole to push the cap open so that the clamping position is clamped on the pole.
[0090] It should be noted that, usually, a cap is encapsulated on the end of the battery pole, so the cap needs to be removed first during testing. Similarly, it is not convenient to manually remove the cap of the batteries in the inner row of the cabinet due to limited operating space. Therefore, in this embodiment, an opening rod 124 is provided, and the opening end of the opening rod 124 protrudes from the first clamping end, so when the operating rod 110 approaches the battery pole, the opening end first approaches the cap, so that the opening end can be abutted against the cap and the cap can be pushed open. After the end of the pole is exposed, the operating rod 110 is continued to be operated to clamp the clamping position at the end of the pole, and then the measurement can be started.
[0091] In some embodiments, the test head 120 further includes a second tension member 125 .
[0092] One end of the opening rod 124 is rotatably disposed on the main rod 121 , and one end of the second stretching member 125 is connected to the main rod 121 , and the other end is connected to the opening rod 124 .
[0093] When the opening rod 124 is received in the receiving through hole 131 , the opening rod 124 is squeezed by the inner wall of the receiving through hole 131 and rotates toward the main rod 121 to compress the second tensioning member 125 .
[0094] Exemplarily, the second tensioning member 125 is a spring; in other embodiments, the second tensioning member 125 may also be a spring, which will not be listed here one by one.
[0095] Exemplarily, one end of the opening rod 124 is hinged to the main rod 121 .
[0096] It should be noted that, similarly, with reference to the above-mentioned clamping rod 122, when the opening rod 124 is received in the receiving hole 131, the opening rod 124 is squeezed by the inner wall of the receiving hole 131 and rotates toward the main rod 121 to compress the second stretching member 125. Therefore, when the opening rod 124 is received in the receiving hole 131, it is compressed toward the main rod 121. After the opening rod 124 extends out of the receiving hole 131, the second stretching member 125 unfolds and is about to unfold. The significance of such a setting is that the overall radial width of the test head 120 in the receiving hole 131 is reduced, and its effect is consistent with the setting of the clamping rod 122 connecting the first stretching member 123, which will not be repeated here.
[0097] In some embodiments, the test assembly 100 further includes a penetration piece 160 , which is disposed on the protection tube 130 , and an end of the operating rod 110 away from the test head 120 is penetrated through the penetration piece 160 ;
[0098] The penetration sheet 160 is provided with an inserting through hole.
[0099] The penetration piece 160 is disposed at one end of the protection tube 130 away from the test head 120 , and one end of the operating rod 110 away from the test head 120 passes through the insertion through hole to extend to the outside of the protection tube 130 .
[0100] It should be noted that the penetration piece 160 is arranged at one end of the receiving through hole 131 close to the gripping end of the operating rod 110; based on the above, it can be known that since the receiving through hole 131 is used to receive the test head 120, the diameter of the receiving through hole 131 is much larger than the diameter of the operating rod 110. In order to prevent the gripping end of the operating rod 110 from swinging significantly, the penetration piece 160 is arranged, and the diameter of the plug-in through hole is slightly larger than the diameter of the operating rod 110. This embodiment controls the swing of the gripping end of the operating rod 110 by plugging the through hole; in addition, the penetration piece 160 can close one end of the protective tube 130 to the greatest extent, thereby achieving the purpose of protecting the test head 120 received in the receiving through hole 131.
[0101] In some embodiments, the diameter of the plug-in through hole is greater than the diameter of the operating rod 110 (in the range of 5 mm-15 mm).
[0102] Figure 2 Another schematic diagram of the battery testing device provided in an embodiment of the present application.
[0103] See also Figure 2 In some embodiments, the number of test components 100 is two.
[0104] The testing device further includes a connecting tube 500 , one end of which is connected to the protection tube 130 of one testing component 100 , and the other end of which is connected to the protection tube 130 of another testing component 100 .
[0105] The two test heads 120 of the two test assemblies 100 each act on a pole of the same battery.
[0106] Exemplarily, the connection tube 500 is disposed close to an end of the protection tube 130 close to the gripping end of the operating rod 110 .
[0107] It should be noted that there are two poles on each battery, namely a positive pole and a negative pole. Thus, when the number of test components 100 is one, two test components 100 are required for testing. The test head 120 of one test component 100 is connected to the positive pole, and the test head 120 of the other test component 100 is connected to the negative pole. The two test heads 120 of the two test components 100 are respectively connected to the test instruments, thereby forming a test loop to complete the test.
[0108] However, if the two test components 100 are provided separately, it is not convenient to fix the two test components 100 during testing. Therefore, in the present embodiment, two test components 100 are provided for the battery testing device, and the protective tubes 130 of the two test components 100 are connected by a connecting tube 500. When performing a battery test, the test head 120 of one test component 100 corresponds to the positive pole, and the test head 120 of the other test component 100 corresponds to the negative pole. More importantly, at this time, grasping the connecting tube 500 can realize the grasping control of the two test components 100, which is more convenient for the testing operation of the testing device.
[0109] In some embodiments, a connecting rod 200 is further included.
[0110] One end of the connecting rod 200 is connected to one end of the operating rod 110 of one test assembly 100 away from the test head 120 , and the other end is connected to another end of the operating rod 110 away from the test head 120 .
[0111] It should be noted that before and after the test, the test head 120 needs to be pushed out or pulled back into the receiving hole through the operating rod 110. According to the above, the test device includes two test components 100. At this time, a connecting rod 200 is set. By operating the connecting rod 200, the operating rods 110 of the two test heads 120 can be directly operated to improve the convenience of the test operation.
[0112] In some embodiments, two elastic return members 300 are also included.
[0113] One elastic return member 300 is sleeved on one operating rod 110 and is located between one protective tube 130 and the connecting rod 200 ; another elastic return member 300 is sleeved on another operating rod 110 and is located between another protective tube 130 and the connecting rod 200 .
[0114] When the operating rod 110 is operated to move along the axis of the receiving hole 131 to extend the test head 120 out of the receiving hole 131, the connecting rod 200 acts on one end of the elastic return member 300, and the other end of the elastic return member 300 acts on the end of the protective tube 130 close to the connecting rod 200, and the elastic return member 300 is compressed and contracted.
[0115] When the operation on the operating rod 110 is released, the elastic return member 300 rebounds to push the test head 120 into the receiving through hole 131 .
[0116] And / or, at least one fastener 400 is also included.
[0117] At least one operating rod 110 is movably disposed on the connecting rod 200, and at least one operating rod 110 moves along the axis of the connecting rod 200 so that the two operating rods 110 are moved closer to or farther away from each other; the fastener 400 is movably disposed on the operating rod 110, and the fastener 400 acts on the connecting rod 200 to fix the operating rod 110 to the connecting rod 200.
[0118] Exemplarily, the elastic return member 300 is a spring, and the spring is sleeved on the operating rod 110 .
[0119] It should be noted that the elastic return member 300 is located between the connecting rod 200 and the protective tube 130 where the corresponding operating rod 110 is located; in this way, when the connecting rod 200 is pushed toward the protective tube 130 to push the test head 120 out of the receiving through hole 131, one end of the elastic return member 300 finally acts on one end of the protective tube 130 (more specifically, one end of the elastic return member 300 acts on the penetration sheet 160), and the other end acts on the connecting rod 200, and the connecting rod 200 squeezes and contracts the elastic return member 300 during the process of continuously moving toward the protective tube until the clamping position between the second clamping end and the first clamping end on the test head 120 is clamped on the pole. When the test is completed, the thrust on the connecting rod 200 toward the pole is released, the elastic return member 300 extends and releases and pushes the connecting rod 200 to move in the direction away from the protective tube 130. At this time, the operating rod 110 moves with the connecting rod 200, and the clamping position is separated from the pole. Finally, the clamping rod 122 and the opening rod 124 are squeezed by the inner wall of the receiving hole 131 and shrink toward the main rod 121, so that the test head 120 is completely received in the receiving hole 131, and finally the elastic return member 300 returns to its initial state. In this way, the elastic return member 300 helps the test head 120 to separate from the pole and be received in the receiving hole 131, thereby reducing the operating intensity of the operator.
[0120] For example, the number of the operating rods 110 provided with the connecting rod 200 may be one or two, which is not limited here.
[0121] The end of the operating rod 110 is provided with a sliding hole, and the connecting rod 200 is inserted into the sliding hole. The side wall of the sliding hole is provided with a threaded hole, and the fastener is a screw. According to the above, it should be noted that the diameter of the plug-in through hole on the insertion sheet 160 is slightly larger than the diameter of the operating rod 110, so the operating rod 110 can move axially (or be interpreted as moving a small distance) in the connecting rod 200. The significance of the movement is that the distance between the two operating rods 110 is finely adjusted according to the actual distance between the two poles of the tested battery, so as to ensure The test head 120 of the operating rod 110 can be connected to the corresponding pole. In addition, after the position adjustment of the operating rod 110 is completed, the fastener 400 is screwed into the threaded hole and acts on the connecting rod 200 to fix the connecting rod 200; in addition, if only one operating rod 110 is movably connected to the connecting rod 200, only one operating rod 110 can be moved to adjust the distance. If both operating rods 110 are movably connected to the connecting rod 200, one or both operating rods 110 can be moved to adjust the distance.
[0122] In other embodiments, the movable connection method between the operating rod 110 and the connecting rod 200 also includes: a slider is provided at one end of the operating rod 110, a slide rail is provided on the connecting rod 200, the slider is slidably connected to the slide rail, and the threaded hole is provided on the slider.
