Description

Technical Field

[0001] This invention relates to the field of battery voltage measurement technology, and in particular to an auxiliary mechanism for measuring battery voltage. Background Technology

[0002] Battery banks are a crucial component of the DC power supply system in substations and are widely used in power systems. When the AC power supply is normal, the battery banks in the DC system serve as backup power and are in a float-charge state. In the event of an AC power failure, the battery banks rapidly provide energy to loads such as protection and automatic devices, control systems, signaling systems, emergency lighting, and AC uninterruptible power supplies. Therefore, the normal operation of the batteries is of paramount importance to ensuring the safe operation of substation equipment.

[0003] Battery voltage measurement is one of the essential monthly tasks for operators. By measuring battery voltage, substandard batteries can be identified and replaced promptly, ensuring that the batteries remain in normal operating condition over the long term.

[0004] Substation battery banks are typically configured in two groups, each containing dozens or even hundreds of individual batteries. For example, a 500kV substation typically has 54 individual batteries per group. Currently, battery voltage measurement is performed by two people: one person holds the two probes of a multimeter with both hands and inserts them into the positive and negative terminals of the battery, while the other person holds the multimeter and reads the value until all batteries have been measured. However, this method requires two people, and holding the multimeter probes with both hands simultaneously is time-consuming, labor-intensive, and inefficient. Furthermore, due to the dense arrangement and large number of batteries, hands are prone to touching the positive or negative terminals during measurement, posing a safety risk of electric shock, DC short circuit, or grounding. Existing technology includes tools that allow the multimeter probes to slide and adjust on a rail for single-handed measurement. However, fixing the probes on the rail is inconvenient and suffers from low stability in holding the probes, increasing the difficulty of operation and hindering efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary mechanism for measuring battery voltage, which enables operators to complete battery voltage measurement with one hand. The multimeter probes are easy and convenient to grip, and the distance between the two multimeter probes is adjustable, which can effectively improve measurement efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An auxiliary mechanism for measuring battery voltage includes:

[0008] handle;

[0009] A clamping assembly includes a fixing member and a telescopic member. The telescopic member is movably connected to one end of the fixing member and can slide along the length direction of the fixing member. Two clamping assemblies are provided. One of the fixing members is connected to the handle at the end away from the telescopic member, and the two fixing members are rotatably connected at the ends close to the handle.

[0010] The fixing member has a plurality of first clamping slots on one side, and the telescopic member has a second clamping slot on one side. The first clamping slots on the two clamping components can cooperate with each other to clamp the first test pen, and the second clamping slots on the two clamping components can cooperate with each other to clamp the second test pen.

[0038] Example 1

[0039] This invention provides an auxiliary mechanism (hereinafter referred to as "the mechanism") for measuring battery voltage, such as... Figure 1 As shown, the mechanism includes a handle 1 and a clamping assembly 2. The clamping assembly 2 includes a fixing member 21 and a telescopic member 22. The telescopic member 22 is movably connected to one end of the fixing member 21 and can slide along the length of the fixing member 21. There are two clamping assemblies 2. One of the fixing members 21 is connected to the handle 1 at the end away from the telescopic member 22. The two fixing members 21 are rotatably connected at the ends close to the handle 1. The fixing member 21 has multiple first clamping slots 211 on one side and the telescopic member 22 has a second clamping slot 221 on one side. The first clamping slots 211 on the two clamping assemblies 2 can cooperate with each other to clamp the first test pen, and the second clamping slots 221 on the two clamping assemblies 2 can cooperate with each other to clamp the second test pen.

[0040] This device features a handle 1 for easy handheld measurement of battery voltage. Two clamping components 2 are rotatably connected at the ends of two fixing members 21, allowing them to be in both open and closed states, thus clamping the test leads. This convenient clamping process improves the efficiency of battery voltage measurement. The handle 1 is connected to the end of one of the fixing members 21, allowing the clamping component 2 to be moved to the measurement position by holding the handle 1.

[0041] The first test probe is held in place by the first clamps 211 on the two fixed members 21, and the second test probe is held in place by the second clamps 221 on the two telescopic members 22. The telescopic members 22 can slide along the length of the fixed members 21, and the multiple first clamps 211 allow for adjustable distance between the first and second test probes to accommodate different battery specifications when measuring voltage, thus improving the applicability of the mechanism.

[0042] When using this mechanism, with both clamping components 2 in the open state, place the first test probe in the corresponding position of the first clamp 211 and the second test probe in the corresponding position of the second clamp 221. Rotate one of the clamping components 2 to close both clamping components 2, thereby clamping the first and second test probes. Adjust the distance between the first and second test probes according to the battery to facilitate voltage measurement.

[0043] Optionally, such as Figures 1-3 As shown, the handle 1 includes a connecting rod 11 and a hand handle 12. One end of the connecting rod 11 is connected to the fixing member 21, and the other end is connected to the hand handle 12. The hand handle 12 is covered with a rubber insulating sleeve.

[0044] The connecting rod 11 extends the distance between the operator's hand position and the battery voltage measurement position, reducing operator movement and workload. The handle 12 is fitted with a rubber insulating sleeve, which increases friction and prevents slippage during operation, while also reducing the risk of electric shock.

[0045] Optionally, the telescopic member 22 includes a sliding part 222 and a bending part 223. One end of the bending part 223 is connected to the sliding part 222, and a second clamping opening 221 is provided on the side of the other end of the bending part 223.

[0046] The bending portion 223 allows the second clamps 221 on the two telescopic members 22 to cooperate in clamping the second test leads, while also ensuring that the width of the sliding portion 222 is smaller than the width of the fixing member 21. This reduces the volume of the telescopic member 22, thereby reducing its weight and facilitating use. Preferably, the bending portion 223 and the sliding portion 222 are arranged at right angles, and the fixing member 21 is rectangular. This allows the bending portion 223 to abut against the end of the fixing member 21 when the telescopic member 22 slides towards the handle 1, improving stability and facilitating storage. Specifically, the telescopic member 22 can be designed as a foldable structure to increase the range of distance adjustment between the two test leads.

[0047] Optionally, a cavity 212 is provided at the end of the fixing member 21 away from the handle 1, and the telescopic member 22 is slidably connected in the cavity 212 and can slide along the axial direction of the cavity 212.

[0048] The cavity 212 provides guidance and storage for the telescopic component 22, reduces the connection structure between the telescopic component 22 and the fixing component 21, and simplifies the mechanism. The cavity 212 increases the strength of the fixing component 21 while reducing its weight, making it easier for the operator to hold.

[0049] Optionally, a damping slide rail is provided inside the cavity 212, and the sliding part 222 is slidably connected to the cavity 212 through the damping slide rail.

[0050] The damping slide rail allows the sliding part 222 to slide out or retract the telescopic member 22 when subjected to external force, thus avoiding accidental sliding during use and causing inconvenience.

[0051] Optionally, such as Figures 1-5 As shown, each of the two fixing members 21 is provided with a first connecting member 213. The first connecting member 213 has a through hole. The first rotating shaft 3 passes through the through hole to connect the two first connecting members 213. A torsion spring is sleeved on the first rotating shaft 3, which can keep the two clamping components 2 with the first clamping mouth 211 and the second clamping mouth 221 in a close fit when there is no external force.

[0052] Specifically, the first connector 213 may include two spaced-apart connecting pieces, each with a through hole. The first rotating shaft 3 passes through four through holes in sequence to connect the two first connectors 213. A torsion spring keeps the two clamping assemblies 2 in a closed state when no external force is applied, facilitating storage.

[0053] Optionally, the handle 1 and the fixing member 21 are connected by a second connector 214. The second connector 214 is disposed at the end of the fixing member 21. The width of the second connector 214 is greater than the width of the fixing member 21. The second connector 214 is provided with a second rotating shaft 2141. The second rotating shaft 2141 is on the same straight line as the contact surface of the two clamping components 2. The end of the connecting rod 11 away from the hand handle 12 is provided with a connecting hole 111. The second rotating shaft 2141 cooperates with the connecting hole 111 to connect the connecting rod 11 and the second connector 214.

[0054] The second connecting piece 214 is fixedly connected to the end of the fixing piece 21, allowing the fixing piece 21 to engage with the handle 1 through the cooperation of the second rotating shaft 2141 and the connecting hole 111. It is understood that the second rotating shaft 2141 could also be a damping gear or damping groove, capable of rotating under external force and remaining fixed when not under external force. Because the width of the second connecting piece 214 is greater than the width of the fixing piece 21, the second rotating shaft 2141 on the second connecting piece 214 is positioned on the straight line of the contact surfaces when the two clamping assemblies 2 are in the closed state. This ensures balanced force when the operator holds the handle 1, preventing instability caused by handle 1 misalignment and ensuring optimal performance. During use, the handle 1 can be rotated to create an angle between the connecting rod 11 and the length direction of the fixing piece 21, facilitating voltage measurement.

[0055] Optionally, continue to refer to Figures 1-5 One of the two first connectors 213 is located on one side of the second connector 214, and the other first connector 213 is located at one end of the other fastener 21. When there is no external force, the two first connectors 213 are arranged at right angles.

[0056] When the two clamping components 2 are in the closed state, the end of the fixing member 21 not connected to the handle 1 can abut against the second connecting member 214 under the elastic force of the torsion spring. The two first connecting members 213 are set at right angles, which can make the force at the connection between the two first connecting members 213 and the fixing member 21 uniform and avoid stress concentration.

[0057] Optionally, both the first clamp 211 and the second clamp 221 include an arc-shaped surface with anti-slip texture.

[0058] The rounded surface reduces damage to the test leads, and the anti-slip texture increases friction when holding the test leads, preventing them from falling off during voltage measurement.

[0059] Optionally, the first clamp 211 and the second clamp 221 are provided with rubber insulation.

[0060] In order to hold the test pen, the arc-shaped surfaces of the first clamp 211 and the second clamp 221 may be designed to clamp the test pen. To reduce damage to the test pen, rubber insulating parts can be added and fixed to the first clamp 211 and the second clamp 221. When the test pen is held, the elasticity of the rubber buffers the clamping force, while also playing a role in anti-slip and insulation, thus avoiding accidental electric shock.

[0061] Optionally, both the handle 1 and the clamping assembly 2 are made of fiberglass epoxy resin.

[0062] Fiberglass epoxy resin has strong insulation properties, which can improve operational safety, and it also has high strength and long service life.

[0063] In use, hold the two clamping components 2 by rotating their ends to separate them, placing the first and second test probes in the first clamp 211 and second clamp 221 respectively. Remove external force; the torsion spring keeps the two clamping components 2 in contact, clamping the test probes securely. Depending on the distance between the positive and negative terminals of the battery, select different first clamps 211 and adjust the sliding length of the telescopic component 22 relative to the fixed component 21 to adjust the clamping distance between the two test probes. Adjust the angle between the handle 1 and the clamping components 2 according to actual conditions to meet ergonomic requirements during measurement, avoiding operator fatigue and discomfort, thereby improving work efficiency. After measurement, rotate the two clamping components 2 again to remove the test probes. One side of the first clamp 211 and second clamp 221 of the two clamping components 2 will automatically return to a contact position. Retract the telescopic component 22 into the cavity 212 of the fixed component 21, and rotate the handle 1 to a convenient storage position.

[0064] This mechanism allows for battery voltage measurement to be performed by a single person, saving manpower and improving efficiency. It eliminates the need for hands during measurement, making it easy to operate. The handle 1, made of insulating material, prevents accidental electric shock during voltage measurement, ensuring operator safety. The folding and telescopic design of the handle 1 facilitates storage and portability. The sliding connection between the telescopic component 22 and the fixing component 21, along with multiple first clamps 211, allows for adjustment of the distance between the two test leads, making the mechanism suitable for batteries of different specifications or arrangements, demonstrating excellent versatility and applicability.

[0065] Example 2

[0066] This embodiment provides an auxiliary mechanism for measuring battery voltage, which is basically the same as the auxiliary mechanism for measuring battery voltage in Embodiment 1, except that the structure of the clamping component 2 is different.

[0067] In this embodiment, the telescopic member 22 is sleeved outside the fixed member 21. A cavity can be provided inside the telescopic member 22 to allow the fixed member 21 and the telescopic member 22 to slide together. Alternatively, a connecting structure can be used to allow the telescopic member 22 and the fixed member 21 to slide together. In this case, both the first clamp 211 and the second clamp 221 are provided on the telescopic member 22. The distance between the two test probes can be adjusted by clamping them at different positions.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
