Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow battery technology, and in particular to an inspection tool. Background Technology
[0002] Flow batteries, also known as redox flow batteries, offer advantages such as relative stability, flexible design, high efficiency, environmental friendliness, and large-scale energy storage. Currently, the sealing methods for flow battery stacks are mainly line sealing and surface sealing. As a key component separating the anode and cathode chambers, the length and extension of the sealing line directly affect the stability and safety of the equipment's operation. If the sealing line malfunctions, it can lead to electrolyte leakage, potentially damaging the equipment itself and causing safety accidents, such as sudden leaks splashing onto workers and other electronic equipment, resulting in burns, electric shocks, and other incidents.
[0003] In existing technologies, the length and extension of the sealing line are generally measured using a measuring tape. However, when measuring length, the measuring tape is prone to errors in measurement and reading, especially on curved or irregularly shaped sealing lines, where the error range is even larger. When measuring the extension of the sealing line, the measuring tape is inconvenient to place, and the readings before and after extension are also prone to errors. Therefore, there is an urgent need to propose a solution to these problems. Utility Model Content
[0004] The purpose of this invention is to provide an inspection fixture to solve the problems of large measurement errors and inconvenience in measuring the length and extension of the sealing line in the prior art.
[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0006] An inspection fixture includes an installation component with a groove. The installation component also includes two sliding components installed in the groove. At least one sliding component can slide along the extension direction of the groove. One sliding component can fix one end of a sealing line, and the other sliding component can fix the other end of the sealing line. The installation component has scale lines along the extension direction of the groove.
[0007] Optionally, both of the sliders can slide along the extension direction of the groove.
[0008] Optionally, the sliding member includes a sliding part and a positioning part connected to each other, the positioning part being used to fix the sealing line, and the sliding part being slidably installed in the groove.
[0009] Optionally, the two side walls of the slide groove are provided with mounting grooves along the length of the slide groove, and the two ends of the sliding part are installed in the two mounting grooves respectively.
[0010] Optionally, the groove extends at least through one side of the mounting member so that the sliding member is mounted in or detached from the groove.
[0011] Optionally, the inspection fixture further includes a locking component, which includes a screw portion and an abutment portion. The sliding portion has a threaded hole on the side away from the positioning portion. The screw portion and the threaded hole cooperate. Rotation of the screw portion can cause the abutment portion to move towards the mounting component to abut against the mounting component.
[0012] Optionally, the radial cross-section of the abutment portion is circular.
[0013] Optionally, the mounting member is elongated, and the groove extends along the length of the mounting member.
[0014] Optionally, the axial cross-section of the slider is T-shaped.
[0015] Optionally, the sliding member has a weight-reducing hole along its own axial direction.
[0016] The beneficial effects of this utility model are:
[0017] The present invention proposes an inspection fixture, including an installation component with a groove. The inspection fixture also includes two sliding components installed in the groove. At least one sliding component can slide along the extension direction of the groove. One sliding component can fix one end of the sealing line, and the other sliding component can fix the other end of the sealing line. The installation component has scale lines along the extension direction of the groove. When inspecting the length of the sealing line, simply fix one end of the sealing line to a sliding member and the other end to another sliding member. Then move one sliding member to straighten the sealing line naturally. The length of the sealing line can then be read using the scale on the mounting piece to determine if the length is acceptable. Because this inspection fixture allows the sealing line to be straight, it avoids the large errors that occur when measuring the length with a tape measure. When inspecting the extension of the sealing line, simply connect the measuring end of a tensile tester to a sliding member. Pulling the tensile tester moves the sliding member. The extension length of the sealing line can be determined based on the standard reading of the tensile tester and the reading on the scale on the mounting piece. This avoids the inconvenience of placing a tape measure and also avoids large errors in the readings before and after the sealing line extends. In short, this inspection fixture is simple to operate, highly accurate, and improves user satisfaction. Attached Figure Description

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] This embodiment provides an inspection fixture to solve the problems of large measurement errors and inconvenience in measuring the length and extension of the sealing line in the prior art.
[0031] like Figure 1 As shown, the inspection fixture includes a mounting part 1, on which a groove 11 is provided. The inspection fixture also includes two sliding parts 2, which are installed in the groove 11. At least one sliding part 2 can slide along the extension direction of the groove 11. One sliding part 2 can fix one end of the sealing line, and the other sliding part 2 can fix the other end of the sealing line. The mounting part 1 has scale lines along the extension direction of the groove 11.
[0032] Understandably, when it is necessary to inspect the length of the sealing line, only one end of the sealing line needs to be fixed to a sliding member 2, and the other end of the sealing line needs to be fixed to another sliding member 2. Then, one sliding member 2 is moved to allow the sealing line to straighten naturally. The value of the scale line corresponding to the sealing line is then read using the scale on the mounting member 1. This reading is compared with the standard length value. If the difference is within the preset range, the length of the sealing line can be determined to be qualified. Since the inspection fixture in this embodiment can keep the sealing line straight, it avoids the large error that occurs when using a measuring tape to measure the length of the sealing line. When it is necessary to inspect the extension of the sealing line, only the tension needs to be increased. The measuring end of the tester is connected to a sliding member 2. Pulling the tensile tester moves the sliding member 2, keeping the reading of the tensile tester within the target range. At this time, the value of the scale line corresponding to the sealing line is read. This reading is compared with the reading when the sealing line is not stretched. If the difference is within the preset range, it can be determined that the stretching length of the sealing line meets the standard. By setting the scale on the mounting part 1, there is no need to place a measuring tape, avoiding the inconvenience of placing a measuring tape. It also avoids the phenomenon of large errors in the readings before and after the sealing line is stretched. That is, the inspection fixture proposed in this embodiment is simple to operate and has high inspection accuracy, improving user satisfaction.
[0033] For example, the difference between the sealing line length and the standard length is 5cm-10cm; if it falls within this range, the sealing line length is considered acceptable. This range ensures that the sealing line length conforms to the battery shape, thereby improving the sealing capability of the sealing line.
[0034] For example, the difference between the unextended length and the extended length of the sealing line is 10cm-20cm. If it falls within this range, the sealing line extension is considered acceptable. This range ensures that even when the battery is under pressure, the sealing line length remains sufficient to maintain a tight seal.
[0035] It is worth mentioning that the difference between the sealing line length and the standard length, and the difference between the unextended length and the extended length of the sealing line, can be set as needed according to the battery's sealing rating and the sealing line model, without too many restrictions here.
[0036] Optionally, the mounting component 1 is elongated, and the groove 11 extends along the length of the mounting component 1. This design improves the portability of the mounting component 1, thereby expanding the applicable scenarios for the inspection fixture.
[0037] Optionally, both sliding members 2 can slide along the extension direction of the slide groove 11. This configuration improves the flexibility of the inspection fixture, allowing the sealing line to be fixed at any position of the mounting member 1, avoiding interference between the mounting member 1 and other equipment on site, thereby enhancing the adaptability of the inspection fixture.
[0038] To improve the structural rationality of the inspection fixture, the sliding member 2 may optionally include a sliding part 22 and a positioning part 21 connected together. The positioning part 21 is used to fix the sealing line, and the sliding part 22 is slidably installed in the slide groove 11. This arrangement allows the sliding member 2 to move more smoothly and facilitates the fixing of the sealing line, thereby improving the structural rationality of the inspection fixture.
[0039] Optionally, the diameter of the end of the positioning part 21 away from the sliding part 22 gradually decreases. Specifically, the end face of the end of the positioning part 21 away from the sliding part 22 is a plane or a spherical surface. This design avoids the end of the positioning part 21 being too sharp, thereby preventing scratches to workers. In addition, this design also facilitates the fixing of the sealing line to the positioning part 21, improving the structural rationality of the inspection fixture.
[0040] To improve the stability of the sliding member 2, the axial cross-section of the sliding member 2 may optionally be T-shaped. This design can improve the structural stability of the sliding member 2, extend its service life, and thus enhance the user experience of the inspection fixture.
[0041] For example, the large end of the T-shaped slider 2 forms a sliding part 22, and the small end forms a positioning part 21. This arrangement can improve the sliding stability of the slider 2, prevent the slider 2 from tipping over or getting stuck during sliding, thereby improving the reliability of the inspection fixture.
[0042] Optionally, both sides of the slide 11 have mounting grooves 12 along the length of the slide 11, and the two ends of the sliding part 22 are installed in the two mounting grooves 12 respectively. This arrangement can limit the sliding part 22 of the sliding member 2 to be located in the mounting groove 12, preventing the sliding member 2 from easily disengaging from the slide 11, thereby further improving the sliding stability of the sliding member 2 and thus improving the reliability of the inspection tooling.
[0043] To improve the usability of the inspection fixture, optionally, the fixture also includes a locking component. The locking component includes a screw portion and an abutment portion. A threaded hole is provided on the side of the sliding portion 22 away from the positioning portion 21. The screw portion and the threaded hole cooperate, and rotation of the screw portion causes the abutment portion to move closer to the mounting part 1 to abut against the mounting part 1. Understandably, when it is necessary to fix the sealing line at any position on the mounting part 1, this design allows the abutment portion to be abutted against the mounting part 1 at any time by tightening the screw portion, thereby locking one or both sliding parts 2. This facilitates length readings of the sliding parts 2, thereby improving the ease of use of the inspection fixture and enhancing the user experience.
[0044] Optionally, the radial cross-section of the abutment portion is circular. This design allows for a smoother abutment portion, preventing cuts to workers and thus improving the usability of the inspection tooling.
[0045] To facilitate easy disassembly of the sliding component 2, the slide groove 11 may optionally extend at least one side of the mounting component 1, allowing the sliding component 2 to be installed in or detached from the slide groove 11. This design allows for the selection of different models of sliding components 2 depending on the type of sealing line. Replacement is achieved by removing or inserting the sliding component 2 from the open side of the mounting component 1, thus expanding the functionality of the inspection fixture.
[0046] Optionally, the slider 2 has a weight-reducing hole along its own axial direction. This feature can reduce the weight of the slider 2, thereby improving the portability of the inspection fixture.
[0047] The process of using the inspection fixture in this embodiment is as follows:
[0048] Prepare the necessary sealing lines for inspection, observe their condition, and confirm that there is no damage or corrosion.
[0049] Install the sliding member 2 that matches the model of the sealing line to be inspected into the sliding groove 11, and then fix the two ends of the sealing line to the two sliding members 2 one by one.
[0050] Move the sliding component 2 to straighten the sealing line naturally without any looseness, read the scale corresponding to both ends of the sealing line, compare the reading with the standard length value, and determine whether the difference is within the preset range, thereby determining whether the length of the sealing line is qualified.
[0051] Tighten the screw of one of the sliding parts 2 until its abutting part is pressed against the mounting part 1. Connect the measuring end of the tensile tester to the other sliding part 2. Pull the tensile tester to move the sliding part 2 so that the reading of the tensile tester is maintained within the target range. At this time, read the reading of the scale corresponding to the sealing line. Compare this reading with the reading when the sealing line is not stretched, and determine whether the difference is within the preset range, thereby determining whether the stretching of the sealing line is qualified.
[0052] After use, slide the slider 2 out of the groove 11 and store it, and put away the mounting part 1.
