Description

Technical Field

[0001] This utility model relates to a high-efficiency leak detection tool and belongs to the field of high-efficiency leak detection technology. Background Technology

[0002] In the past, there have been many problems to be solved in the leak detection of high-efficiency filters (HEPA filters). On the one hand, because HEPA products come in various specifications and sizes, traditional leak detection tools have a fixed enclosure structure and cannot be flexibly adjusted according to different sizes of HEPA filters. As a result, when testing different specifications of HEPA filters, it is necessary to prepare a variety of leak detection devices of different sizes. This not only increases equipment costs and occupies a lot of storage space, but also the frequent replacement of equipment greatly reduces the efficiency of leak detection work.

[0003] On the other hand, the efficient disassembly and assembly process also presents many inconveniences. High-efficiency leak detectors are typically fixed to their mounting positions with bolts and sealed with sealant. Disassembly requires manual removal of each bolt and laborious prying of the detector out of its mounting position, a tedious and labor-intensive process that is prone to damage due to improper handling. Similarly, installation requires careful manual placement of the detector in the correct position and tightening of each bolt. The entire disassembly and assembly process is inefficient and cannot meet the needs of large-scale, high-frequency leak detection. Therefore, an efficient leak detection tool is proposed. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a high-efficiency leak detection tool that can meet diverse detection needs, effectively improve the efficiency of leak detection work, reduce the difficulty and error of manual operation, and provide a reliable and convenient solution for efficient leak detection work.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a high-efficiency leak detection tool, comprising: The box body has an upward-facing storage cavity inside; A lifting seat is disposed in a storage cavity and is lifted and lowered via a fork-scissor assembly. The lifting seat is provided with a surrounding plate above it, and the surrounding plate and the lifting seat form a sealed cavity for covering the high efficiency. The lifting seat is provided with a support plate, and at least one smoke detector is provided on the upper surface of the support plate.

[0006] Preferably, the enclosure includes four sliding plates that slide around the lifting seat, with corner plates provided between adjacent sliding plates; As the sliding plate and corner plate converge and slide towards the center of the lifting platform, the enclosure shrinks. As the skateboard and corner board slide toward the edge of the lifting seat, the enclosure expands. Preferably, a connecting block is fixed to the middle of each of the four sliding plates, and a central block is provided in the middle of the lifting base. The central block is driven to rotate by a motor and connected to a winding wheel. Four pull ropes are provided on the winding wheel, and the end of each pull rope is connected to the corresponding connecting block. A return spring is fitted onto the pull rope, with one end of the return spring abutting against the connecting block and the other end abutting against the center block.

[0007] Preferably, the side wall of the slide plate is provided with a sliding groove, and the side wall of the corner plate is provided with a sliding rod, which is slidably connected inside the sliding groove.

[0008] Preferably, the upper surface of the support plate is provided with a cross-shaped boss for supporting high efficiency, and a hydraulic cylinder is fixed at the bottom of the lifting seat, with the output shaft of the hydraulic cylinder fixed on the side wall of the support plate. When the hydraulic cylinder is running, the output shaft of the hydraulic cylinder drives the support plate to move up and down within the lifting seat.

[0009] The upper surface of the cross-shaped boss is higher than the smoke detector.

[0010] Preferably, each of the two opposing slide plates has a rotating insert plate, and the side wall of the insert plate is provided with barbs; Magnets are provided on the side walls of both the insert plate and the slide plate; When the insert plate rotates upwards and unfolds, the magnets of the insert plate and the slide plate attract each other, keeping the insert plate in an upward-unfolded state.

[0011] Preferably, the housing is provided with a first cover for closing the storage cavity.

[0012] Preferably, the box body is provided with a storage cavity for storing spare high-efficiency containers, and the opening of the storage cavity is provided with a second box cover.

[0013] Preferably, the bottom of the housing is provided with casters.

[0014] Compared with existing technologies: 1. This utility model, when testing different sizes of high-efficiency components, features a enclosure consisting of four sliding plates and corner plates that can slide flexibly around the lifting base. A motor drives a winding wheel to rotate a pull rope, easily causing the sliding plates and corner plates to slide in a concentrated or diffused manner, allowing for free adjustment of the enclosure size. Combined with a return spring, the sliding plates automatically unfold when the pull rope is released, improving the equipment's versatility and applicability, meeting diverse testing needs, effectively increasing leak detection efficiency, and reducing the difficulty and error of manual operation.

[0015] 2. This utility model features a cross-shaped boss on the support plate, providing stable support for the high-efficiency unit while preventing it from pressing against the smoke detector. A hydraulic cylinder drives the support plate to rise and fall within the lifting seat, guided by a second guide rod, ensuring stable movement and facilitating the smooth placement and removal of the high-efficiency unit. The insert plate on the sliding plate has barbs; during disassembly, these barbs are inserted into the edge gaps of the high-efficiency unit, overcoming the adhesive properties of the sealant to pull the unit out of its mounting position, greatly reducing disassembly difficulty.

[0018] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0019] Example 1 like Figures 1-12 As shown in the figure, in this embodiment, a high-efficiency leak detection tool is provided, including a box 1, and a storage cavity 101 with an upward opening is provided in the box 1; a lifting seat 2 is provided in the storage cavity 101, and the lifting seat 2 is lifted and lowered by a fork and scissor assembly 3. The fork and scissor assembly 3 is disposed in the storage cavity 101 and located below the lifting seat 2. The fork and scissor assembly 3 performs telescopic movement within the storage cavity 101, causing the upper end of the fork and scissor assembly 3 to drive the lifting seat 2 to rise or fall. The fork and scissor assembly 3 is a prior art structure and is not a necessary technical feature of this application, so it will not be described in detail. The lifting seat 2 is provided with a surrounding plate 4 above it. The surrounding plate 4 and the lifting seat 2 form a sealed cavity for covering the high efficiency. The lifting seat 2 is provided with a support plate 5. At least one smoke detector 6 is provided on the upper surface of the support plate 5 for detecting whether the high efficiency is leaking.

[0020] The housing 1 is provided with a first cover 102 for closing the storage cavity 101.

[0021] The housing 1 is provided with a storage cavity 103 for storing spare high-efficiency containers, and the opening of the storage cavity 103 is provided with a second cover 104.

[0022] A caster wheel 105 is installed at the bottom of the box 1.

[0023] In addition, such as Figure 1 As shown, a power compartment is provided on the housing 1 and below the storage cavity 101. The power compartment contains power equipment, such as a battery. The battery is electrically connected to each power component to provide it with power.

[0024] Example 2 Based on Embodiment 1, in this embodiment, to facilitate efficient detection of objects of different sizes, the enclosure 4 includes four sliding plates 401. These four sliding plates 401 slide around the lifting seat 2, as shown below. Figure 10 As shown, the lifting seat 2 is provided with a first guide rod 202 for guiding the sliding of the slide plate 401, and a corner plate 402 is provided between two adjacent slide plates 401; When the sliding plate 401 and the corner plate 402 slide together toward the center of the lifting seat 2, the enclosure plate 4 shrinks, which can then cover the smaller high-efficiency unit. As the sliding plate 401 and the corner plate 402 slide towards the edge of the lifting seat 2, the enclosure 4 expands, which can then cover the larger high-efficiency unit. Each of the four sliding plates 401 has a connecting block 403 fixed to its center. A center block 201 is located in the center of the lifting base 2. The center block 201 is connected to a winding wheel 8 via a motor 7. The motor 7 is fixedly mounted on the lifting base 2, and its output shaft is connected to the winding wheel 8. When the motor 7 operates, its output shaft drives the winding wheel 8 to rotate. Four pull ropes 9 are mounted on the winding wheel 8, and the end of each pull rope 9 is connected to a corresponding connecting block 403. Among them, a return spring 10 is sleeved on the pull rope 9. One end of the return spring 10 abuts against the connecting block 403, and the other end abuts against the center block 201.

[0025] When the motor 7 starts and rotates the winding wheel 8 to wind the pull rope 9, the pull rope 9 will drive the slide plate 401 to slide towards the middle of the lifting seat 2 through the connecting block 403. The enclosure 4 gradually decreases in size. When sliding, the return spring 10 gradually compresses. When the winding wheel 8 rotates in the opposite direction to release the pull rope 9, the return spring 10 drives the four slide plates 401 to unfold, and the enclosure 4 gradually increases in size.

[0026] In addition, the process of adjusting the size of the aforementioned enclosure 4 can be controlled by the controller to operate the motor 7, and the adjustment can be made with reference to the existing high-efficiency dimensions.

[0027] The slide plate 401 has a slide groove 4011 on its side wall, and the corner plate 402 has a slide rod 4021 on its side wall. The slide rod 4021 is slidably connected to the inside of the slide groove 4011.

[0028] The leak detection process is as follows: Open the first box cover 102, then adjust the size of the enclosure 4 to match the high-efficiency dimensions, and use the forklift assembly 3 to raise the lifting seat 2 to the high-efficiency position (e.g., Figure 4 As shown), the enclosure 4 and the lifting seat 2 will be effectively sealed; After completion, the forklift assembly 3 retracts, the lifting seat 2 retracts, and the leak detection is completed.

[0029] Example 3 Based on Embodiment 2, in this embodiment, in order to facilitate the assembly and disassembly of the high efficiency, the upper surface of the support plate 5 is provided with a cross boss 501 for supporting the high efficiency, and the bottom of the lifting seat 2 is fixed with a hydraulic cylinder 11, the output shaft of the hydraulic cylinder 11 is fixed on the bottom wall of the support plate 5. When the hydraulic cylinder 11 is running, the output shaft of the hydraulic cylinder 11 drives the support plate 5 to move up and down within the lifting seat 2; In addition, in order to make the support plate 5 move stably, a plurality of second guide rods 502 are provided below the support plate 5. The plurality of second guide rods 502 slide on the lifting seat 2, and guide the movement of the support plate 5 through the second guide rods 502, thereby improving the stability of the movement of the support plate 5.

[0030] The upper surface of the cross-shaped boss 501 is higher than that of the smoke detector 6 to prevent the high efficiency of the cross-shaped boss 501 from pressing against the smoke detector 6.

[0031] Each of the two opposing slide plates 401 has a rotating insert plate 12. The side wall of the insert plate 12 is provided with barbs 1201. When disassembling the high efficiency, the insert plate 12 is inserted into the gap, and the barbs 1201 on the insert plate 12 can abut against the side wall of the high efficiency, which can pull the high efficiency (overcoming the stickiness of the sealant) out of the installation position. Magnets 13 are provided on the side walls of both the insert plate 12 and the slide plate 401; When the insert plate 12 rotates upward and unfolds, the insert plate 12 and the magnet 13 of the slide plate 401 attract each other, keeping the insert plate 12 in an upward unfolded state.

[0032] like Figure 11 As shown, the high-efficiency unit is fixed to the mounting position on the roof surface by bolts. There is a gap between the high-efficiency unit and the mounting position, and the high-efficiency unit is sealed with sealant around its perimeter. The process of replacing with a high-efficiency one is as follows: First, manually remove each bolt one by one. After adjusting the size of the enclosure 4, rotate the insert plate 12 to an upward position. Then, use the forklift assembly 3 to raise the lifting platform 2 to the efficient position (e.g., Figure 4 As shown), at this time, the insert plate 12 is inserted into the gap of the high efficiency edge; the hydraulic cylinder 11 is used to move the cross boss 501 of the support plate 5 upward to the bottom position that fits the high efficiency, and then the fork scissor assembly 3 retracts, and the barbs 1201 on the insert plate 12 can press against the high efficiency, which can pull the high efficiency (overcoming the stickiness of the sealant) out of the installation position, and the lifting seat 2 moves down with the high efficiency to complete the removal of the high efficiency; Installation process: Rotate the insert plate 12 downwards to the storage position, take out the spare high-efficiency part from the placement cavity 103, and place the spare high-efficiency part in the cross boss 501. Apply sealant to the high-efficiency part, lift the spare high-efficiency part to the installation position, and use the hydraulic cylinder 11 to move the cross boss 501 of the support plate 5 upwards. The cross boss 501 of the support plate 5 is lifted upwards to the installation position of the high-efficiency part. After the sealant has solidified, retract the lifting seat 2, and then tighten the bolts manually to complete the installation of the high-efficiency part.
