Description

Technical Field

[0001] This utility model relates to the field of flow velocity measurement technology for superconducting magnet gap filling material, and in particular to a device for measuring the flow velocity of superconducting magnet gap filling material. Background Technology

[0002] When measuring the flow rate of the gap filling material in a superconducting magnet, a key step in the manufacturing of the longitudinal field magnet is to inject a mixture of resin and powder into the gap through the injection port reserved in the coil box after the coil is installed into the coil box and sealed. The mixture is then cured by the resin curing process, thereby achieving the function of filling and fixing the coil in the gap.

[0003] Patent application CN219777714U discloses a device for measuring the flow rate of superconducting magnet gap-filling material. The device includes an upper pressure plate and a lower base plate that are detachably connected. The upper pressure plate has an observation hole containing an observation glass. A length scale is provided on the surface of the observation glass away from the lower base plate. A sealing ring is provided between the observation glass and the lower base plate. The sealing ring, the observation glass, and the lower base plate form a test chamber. The lower base plate has a glue injection port and a glue outlet connected to the test chamber. This invention provides a device that, by setting a sealing ring, observation glass, and lower base plate to form a test chamber, connects the test system through the glue injection port and glue outlet to measure the flow rate of the superconducting magnet gap-filling material in different gaps according to the structure and gap-filling process characteristics of the superconducting magnet, ensuring uniform glue filling in the gaps.

[0004] In the aforementioned related technologies, the upper pressure plate and the lower base plate are installed using multiple sets of bolts and nuts, which is time-consuming and labor-intensive to disassemble and install, resulting in low work efficiency. To address these issues, we have introduced a flow velocity measurement device for superconducting magnet gap filling material. Utility Model Content

[0005] This utility model discloses a flow velocity measuring device for superconducting magnet gap filling material, which aims to solve the technical problem in related technologies where the upper pressure plate and lower base plate are installed and disassembled using multiple sets of bolts and nuts, resulting in time-consuming and labor-intensive installation and disassembly, and low work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flow velocity measuring device for superconducting magnet gap filling material includes a lower base plate, an upper pressure plate, and a fixing assembly. The lower base plate and the upper pressure plate are connected by the fixing assembly. The fixing assembly includes fixing strips, which are symmetrically fixedly installed on both sides of the lower base plate. Fixing frames are symmetrically fixedly installed on both sides of the upper pressure plate. Each fixing frame has a threaded rod bolted inside and a locking strip slidably connected inside. The end of the threaded rod near the locking strip extends into the locking strip and is rotatably connected to it. A locking groove is formed on the side of the fixing strip near the locking strip, and the end of the locking strip near the locking groove extends into the locking groove.

[0008] By setting a fixing component, the lower base plate is placed on top of the upper pressure plate, the fixing strip extends into the inside of the fixing frame, and then by rotating the threaded rod, the locking strip is pushed into the slot to complete the fixing of the lower base plate and the upper pressure plate. This facilitates subsequent disassembly and connection, making it more convenient to use. It solves the technical problem in related technologies where the upper pressure plate and lower base plate are installed with multiple sets of bolts and nuts, which is time-consuming, labor-intensive, and inefficient.

[0009] In a preferred embodiment, a measuring cavity is provided on the side of the lower base plate and the upper pressure plate that are close to each other. Positioning grooves are symmetrically and equidistantly provided inside the lower base plate and the upper pressure plate on both sides of the measuring cavity. An inner plate is placed in the middle of the measuring cavity inside the upper pressure plate. A positioning block is fixedly installed on the side of the inner plate that is close to the positioning groove. The positioning block extends into the corresponding positioning groove.

[0010] By setting multiple inner plates of different thicknesses, the gaps of the filling material to be tested can be adjusted. The positioning grooves and positioning blocks help to fix the inner plates more firmly in the measuring cavity inside the bottom plate.

[0011] In a preferred embodiment, a sealing ring is fixedly installed on the side of the lower base plate near the upper pressure plate, and a sealing groove is correspondingly opened on the side of the upper pressure plate near the sealing ring, with the sealing ring extending into the sealing groove.

[0012] Setting up sealing rings and sealing grooves helps to improve the sealing performance of the connection between the bottom plate and the top pressure plate.

[0013] In a preferred embodiment, symmetrical limit grooves are formed inside the side walls of both sides of the fixing frame, and limit blocks are slidably connected inside the limit grooves. The side of the limit block closest to the card strip is fixedly connected to the card strip.

[0014] By using limit grooves and limit blocks together, the stability of the movement of the locking bar is enhanced, and the rotation of the threaded rod is prevented from causing the locking bar to rotate as well.

[0015] In a preferred embodiment, an observation window is fixedly installed in the middle of the top of the upper pressure plate, a scale line is provided on the top of the upper pressure plate near the observation window, an injection port is fixedly installed through one side of the top of the upper pressure plate, and an outlet port is fixedly installed through the other side of the top of the upper pressure plate away from the injection port.

[0016] By setting up a sprue outlet connected to a helium mass spectrometer, the upper pressure plate and scale lines facilitate the observation of the flow velocities of different materials inside the measurement chamber between the lower bottom plate and the upper pressure plate.

[0017] In a preferred embodiment, both the positioning groove and the positioning block are configured as a "T" shaped structure.

[0018] By setting both the positioning slot and the positioning block to be "T" shaped, the system becomes more stable.

[0019] The flow velocity measuring device for superconducting magnet gap filling material provided by this utility model has the following advantages:

[0020] Firstly, by setting a fixing component, the lower base plate is placed on top of the upper pressure plate, the fixing strip extends into the inside of the fixing frame, and then by rotating the threaded rod, the locking strip is pushed into the slot to complete the fixing of the lower base plate and the upper pressure plate. This facilitates subsequent disassembly and connection, making it more convenient to use. It solves the technical problem in related technologies where the upper pressure plate and lower base plate are installed with multiple sets of bolts and nuts, which is time-consuming, labor-intensive, and inefficient.

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The flow velocity measuring device for superconducting magnet gap filling material disclosed in this utility model is mainly used in the scenario of measuring the gap filling material of superconducting magnets.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A flow velocity measuring device for superconducting magnet gap filling material includes: a lower base plate 1, an upper pressure plate 2, and a fixing assembly 3. The lower base plate 1 and the upper pressure plate 2 are connected by the fixing assembly 3. The fixing assembly 3 includes fixing strips 31, which are symmetrically fixedly installed on both sides of the lower base plate 1. Fixing frames 32 are symmetrically fixedly installed on both sides of the upper pressure plate 2. Threaded rods 33 are bolted to the inside of each fixing frame 32, and locking strips 34 are slidably connected to the inside of each fixing frame 32. The end of the threaded rod 33 near the locking strip 34 extends into the inside of the locking strip 34 and is rotatably connected to the locking strip 34. A slot 35 is opened on the side of the fixing strip 31 near the locking strip 34, and the end of the locking strip 34 near the slot 35 extends into the slot 35.

[0029] A sealing ring 36 is fixedly installed on the side of the lower base plate 1 near the upper pressure plate 2, and a sealing groove 37 is correspondingly opened on the side of the upper pressure plate 2 near the sealing ring 36, with the sealing ring 36 extending into the sealing groove 37; by setting the sealing ring 36 and the sealing groove 37, it is beneficial to enhance the sealing performance of the connection between the lower base plate 1 and the upper pressure plate 2.

[0030] The fixing frame 32 has symmetrically provided limit grooves 38 on both sides of the inner wall. Limit blocks 39 are slidably connected inside the limit grooves 38. The side of the limit block 39 closest to the locking strip 34 is fixedly connected to the locking strip 34. By setting the limit grooves 38 and the limit blocks 39 together, it is beneficial to enhance the stability of the movement of the locking strip 34 and to prevent the threaded rod 33 from rotating and causing the locking strip 34 to rotate.

[0031] The upper pressure plate 2 has an observation window 21 fixedly installed in the middle of its top interior. A scale line is set on the top of the upper pressure plate 2 near the observation window 21. A glue injection port 22 is fixedly installed through one side of the top of the upper pressure plate 2. A glue outlet 23 is fixedly installed through the other side of the top of the upper pressure plate 2 away from the glue injection port 22. The glue outlet 23 is connected to the helium mass spectrometer. The upper pressure plate 2 and the scale line facilitate the observation of the flow rates of different materials inside the measuring cavity 4 between the lower base plate 1 and the upper pressure plate 2.

[0032] In this embodiment, by setting the fixing component 3, the lower base plate 1 is placed on top of the upper pressure plate 2, the fixing strip 31 extends into the fixing frame 32, and then by rotating the threaded rod 33, the locking strip 34 is pushed into the locking groove 35 to complete the fixing of the lower base plate 1 and the upper pressure plate 2, which facilitates the subsequent disassembly and connection, making it more convenient to use. This solves the technical problem in related technologies where the upper pressure plate and the lower base plate are installed with multiple sets of bolts and nuts, which is time-consuming, labor-intensive, and has low work efficiency.

[0033] In the above technical solution, considering the adjustment problem of the internal gap between the lower base plate 1 and the upper pressure plate 2, the specific operation is as follows to solve this problem:

[0034] Reference Figure 1 and Figure 4 In a preferred embodiment, a measuring cavity 4 is provided on the side of the lower base plate 1 and the upper pressure plate 2 that are close to each other. Positioning grooves 5 are symmetrically and equidistantly provided inside the lower base plate 1 and the upper pressure plate 2 and on both sides of the measuring cavity 4. An inner plate 6 is placed in the middle of the measuring cavity 4 inside the upper pressure plate 2. A positioning block 7 is fixedly installed on the side of the inner plate 6 that is close to the positioning groove 5. The positioning block 7 extends into the corresponding positioning groove 5.

[0035] Both the positioning groove 5 and the positioning block 7 are designed with a "T" shape; by designing both the positioning groove 5 and the positioning block 7 with a "T" shape, the operation is more stable.

[0036] In this embodiment, by setting multiple inner plates 6 of different thicknesses, the gaps of the filling material to be tested are adjusted. The positioning grooves 5 and positioning blocks 7 help to fix the inner plates 6 more firmly in the measuring cavity 4 inside the bottom plate 1.

[0037] Working principle: In use, by setting the fixing component 3, the lower base plate 1 is placed on top of the upper pressure plate 2, the fixing strip 31 extends into the fixing frame 32, and then by rotating the threaded rod 33, the locking strip 34 is pushed into the locking groove 35 to complete the fixing of the lower base plate 1 and the upper pressure plate 2, which facilitates the subsequent disassembly and connection, making it more convenient to use. It solves the technical problem in related technologies that the upper pressure plate and the lower base plate are installed with multiple sets of bolts and nuts, which is time-consuming, labor-intensive and has low work efficiency.
