[0027] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0030] Please refer to Figures 1 to 3 , Figure 1 The overall structural diagram provided by the embodiment of the present invention is as follows: Figure 2 A schematic diagram of a front cross-sectional structure provided by an embodiment of the present invention, Figure 3 for Figure 2 A partial enlarged view of point A.

[0031] The battery voltage measuring device provided in the embodiment of the present invention is mainly used in the scenario of measuring batteries in a substation. It can measure the voltage of the battery by a single person, saving the time of measuring the voltage, so as to improve the efficiency of measuring the voltage.

[0032] like Figure 1 and Figure 2 As shown, the battery voltage measuring device includes a shell 1, a probe module 2, a transmission mechanism 3, a slide rail 4 and a pressure measuring circuit module; the slide rail 4 is fixedly connected to the shell 1; the probe module 2 is slidably connected to the slide rail 4 on the side of the slide rail 4 away from the shell 1, and the probe module 2 is connected to the pressure measuring circuit module; the transmission mechanism 3 is arranged in the shell 1, and the transmission mechanism 3 is transmission-connected to the probe module 2, and is used to drive the probe module 2 to move toward the direction close to the battery electrode when measuring the battery voltage.

[0033] Specifically, when measuring the battery voltage, the staff aligns the battery voltage device with the battery so that the probe module can slide in a direction perpendicular to the battery pole piece under the action of the slide rail 4, and then the probe module 2 moves toward the direction close to the battery pole piece under the action of the transmission mechanism 3, so that the probe module 2 touches the battery pole piece. When the probe module 2 touches the pole piece, the pressure measuring circuit module is connected to the battery to measure the battery voltage. The voltage measuring process can be completed by only one staff member, without the need to manually adjust the position of the probe, saving time and human resources, and improving the efficiency of measuring battery voltage.

[0034] Furthermore, the probe module 2 includes a first probe 21 and a second probe 22, and the first probe 21 and the second probe 22 are respectively located at two ends of the slide rail 4. Specifically, when measuring the battery voltage, the first probe 21 and the second probe 22 are used as a reference, and the battery is placed between the first probe 21 and the second probe 22, so that the staff can quickly align the battery voltage measuring device with the battery, thereby improving the positioning efficiency of the battery voltage measuring device.

[0035] Furthermore, a first slider 41 is connected between the first probe 21 and the slide rail 4, and a second slider 42 is connected between the second probe 22 and the slide rail 4; the first slider 41 is fixedly connected to the first probe 21, and the first slider 41 is slidably connected to the slide rail 4; the second slider 42 is fixedly connected to the second probe 22, and the second slider 42 is slidably connected to the slide rail 4. The transmission mechanism 3 includes a push rod 31, a compression spring 32, a first connecting rod 33 and a second connecting rod 34; the compression spring 32 abuts against the push rod 31; one end of the first connecting rod 33 is rotatably connected to the push rod 31, and the other end is rotatably connected to the first slider 31; one end of the second connecting rod 34 is rotatably connected to the push rod 31, and the other end is rotatably connected to the second slider 42.

[0036] Specifically, when measuring the battery voltage, the staff holds the housing 1 close to the battery, and the part of the push rod 31 protruding from the housing 1 is against the battery. The staff continuously applies force to the housing 1, so that the push rod 31 moves toward the inside of the housing 1. Since the first connecting rod 33 and the second connecting rod 34 are both rotatably connected to the push rod 31, when the push rod 31 moves toward the inside of the housing 1, the first connecting rod 33 and the second connecting rod 34 will also move toward the inside of the housing 1, so that the end of the first connecting rod 33 connected to the first slider 41 will move toward the push rod 31, that is, the battery, and the second connecting rod 34 is the same. Until the first connecting rod 33 and the second connecting rod 34 are against the battery, the conduction between the pressure measuring circuit module and the battery is completed, and the staff can remove the housing 1 from the battery. At this time, the push rod 31 returns to the initial position under the action of the compression spring 32 to measure the next battery.

[0037] Furthermore, if Figure 2 and Figure 3 As shown, the housing 1 is provided with a transmission installation groove 11 for accommodating the ejector rod 31 and the compression spring 32, the bottom of the transmission installation groove 11 is provided with a through hole, and a compression spring bottom support 12 for contacting the compression spring 32 is penetrated in the through hole; a bolt 13 is fixedly connected to the side of the compression spring bottom support 12 away from the compression spring 32, the housing 1 is provided with a threaded hole for cooperating with the threaded portion 131 of the bolt 13, and the housing 1 is also provided with a receiving groove 14 for accommodating the head 132 of the bolt 13. The compression spring bottom support 12 includes a bottom cylinder penetrated in the through hole, a middle disk for supporting the compression spring 32, and a top cylinder for limiting the position of the compression spring 32.

[0038] Since the types of batteries in different substations are different, the scope of application of the battery voltage measuring device can be expanded by adjusting the degree of compression of the compression spring 32. Specifically, when the size of the battery is generally smaller than the general value, by tightening the bolt 13, the head 132 is further away from the bottom of the accommodating groove 14, so that the compression spring bottom support 12 moves toward the bottom of the transmission mounting groove 11, so that the activity space of the compression spring 32 is further increased, thereby reducing the preset elastic force of the compression spring 32, so that when the staff measures the battery voltage through the battery voltage measuring device, it is more labor-saving to make the probe module 2 contact the battery pole piece, so as to improve the scope of application. When the size of the battery is generally larger than the general value, by loosening the bolt 13, the preset elastic force of the compression spring 32 is increased in the same way, so that the top rod 31 is further away from the bottom of the transmission mounting groove 11, so that the distance between the first probe 21 and the second probe 22 is larger, so as to measure larger batteries, and expand the scope of application of the battery voltage measuring device.

[0039] Furthermore, a sealing baffle 15 is provided at the slot of the receiving groove 14. The sealing baffle 15 reduces the contact between the bolt 13 and the external air, increases the service life of the bolt 13, and prevents the bolt 13 from falling out of the housing 1.

[0040] Furthermore, a limiting portion is convexly provided on one side of the push rod 31 close to the compression spring 32. The limiting portion is provided to prevent the compression spring 32 from deflecting during the compression process, thereby improving the stability of the battery voltage measuring device.

[0041] Furthermore, the battery voltage measuring device also includes an alarm module 5 for prompting that the battery voltage exceeds the rated value, and the alarm module 5 is connected to the pressure measuring circuit module. It should be noted that the rated value refers to the normal value of the battery voltage specified in the safety manual. The alarm module 5 can be an audible alarm device, such as a buzzer, or a light alarm device, such as a light emitting diode, and of course it can also be a combination of a buzzer and a light emitting diode.

[0042] Furthermore, the battery voltage measuring device further comprises a display module 6 for displaying the battery voltage, and the display module 6 is connected to the voltage measuring circuit module. The display module 6 may be a liquid crystal display, through which the staff can easily observe the battery voltage value, thereby improving the readability of the battery voltage measuring device.

[0043] Furthermore, a handle 16 is provided on one side of the housing 1 away from the probe module 2, so that the worker can carry the battery voltage measuring device and can quickly press the push rod 31 onto the battery surface when measuring the voltage.

[0044] In summary, the battery voltage measuring device provided in this embodiment enables a single worker to complete the battery voltage measurement work, thereby reducing manpower expenditure, saving measurement time, and improving measurement efficiency.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
