Description

Technical Field

[0001] This utility model relates to the field of liquid infusion technology for liquid coolers, and specifically to an infusion tool that is easy for a single person to operate. Background Technology

[0002] Liquid coolers (LCUs) have become standard equipment in the thermal management circuits of industrial and commercial energy storage, power battery packs, and sodium-ion batteries. When the equipment leaves the factory or is maintained on-site, it is necessary to inject a specified type and weight of coolant at one time—usually ethylene glycol or propylene glycol-based antifreeze, etc.

[0003] In the current liquid injection process, when the liquid extraction tube is inserted into the filling tank and the water pump is suddenly turned on, the extraction end may swing due to the air pressure difference, which may cause the liquid to splash out. The extraction hose is long and not effectively fixed. The operator needs to hold the tube with one hand and control the pump to start and stop with the other hand, which is inconvenient for a single person to inject liquid independently. Utility Model Content

[0012] As a further embodiment of this utility model: the clamping part includes a fixing block disposed on the mounting base, a fixing shaft movably connected to the fixing block, a fastener disposed on the fixing shaft, and a torsion spring disposed between the fixing shaft and the fastener, wherein the torsion spring provides pressure for the fastener to abut against the mating part.

[0013] As a further embodiment of this utility model: the fastener includes a transmission plate movably connected to the fixed shaft, and a clamping plate adjacent to the transmission plate; the groove is inclined with a wider top and a narrower bottom, and the two sides of the clamping plate are also inclined to fit the shape of the inner side of the groove.

[0014] As a further embodiment of this utility model: the suction end of the infusion tube is sleeved with a force-bearing component, the force-bearing component includes a force-bearing surface, the force-bearing surface is disposed on the inner side of the infusion tube and is designed to be inclined inward.

[0017] As a further embodiment of this utility model, both the infusion tube and the suction tube are fitted with gravity components.

[0018] The beneficial effects of this utility model are as follows: During on-site liquid injection, the liquid extraction pipe and the liquid delivery pipe are fixedly installed at both ends of the water pump, and the liquid delivery end of the liquid delivery pipe is fixedly installed into the liquid delivery port of the liquid cooler. Then, using the fastening mechanism, the fitting part on the liquid extraction pipe is inserted into the clamping part on the bracket. The clamping end of the clamping part is inserted into the groove on the fitting part, which can clamp the fitting part and thus fasten the liquid extraction end of the liquid extraction pipe into the loading tank.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] See Figures 1-4An embodiment of the present invention provides an infusion fixture that is easy for single-person operation, comprising a loading tank 1, a fastening mechanism 2, a suction pipe 3, a water pump 4, and an infusion pipe 5; the infusion port of the water pump 4 is connected to the suction pipe 3, and the infusion port of the water pump 4 is connected to the infusion pipe 5; one end of the suction pipe 3 away from the water pump 4 is inserted into the loading tank 1, and the other end of the suction pipe 3 away from the water pump 4 is inserted into the infusion port of the liquid chiller; the infusion end of the infusion pipe 5 is inserted into the infusion port of the liquid chiller using a traditional quick-connect connector, and then locked with a stainless steel clamp or nylon cable tie; the fastening mechanism 2 includes a bracket 21 disposed in the loading tank 1, a clamping part 22 disposed on the bracket 21, and a mating part 23 disposed on the infusion pipe 5; the mating part 23 has a groove 231, and the mating part 23 can be fixed on the bracket 21 by the cooperation of the clamping part 22 and the groove 231.

[0032] Specifically, during on-site liquid injection, the liquid extraction pipe 3 and the liquid delivery pipe 5 are fixedly installed at both ends of the water pump 4, and the liquid delivery end of the liquid delivery pipe 5 is fixedly installed into the liquid delivery port of the liquid chiller. Then, using the fastening mechanism 2, the fitting part 23 on the liquid extraction pipe 3 is inserted into the clamping part 22 on the bracket 21. The clamping end of the clamping part 22 is inserted into the groove 231 on the fitting part 23, which can clamp the fitting part 23 and thus fasten the liquid extraction end of the liquid extraction pipe 3 into the loading tank 1.

[0033] Furthermore, this tooling effectively improves the situation where the suction end of the suction pipe 3 is pulled due to the negative pressure change caused by the start of the water pump 4, thereby effectively preventing coolant splashing. In addition, this tooling fixes the suction end of the suction pipe 3 inside the loading tank 1, which can prevent the suction pipe 3 from detaching from the loading tank 1 and avoid the occurrence of liquid spraying when the suction pipe 3 detaches from the loading tank 1 during the on-site liquid injection process. When injecting liquid on-site, the staff does not need to hold the pipe with one hand and control the pump start and stop with the other.

[0034] See Figures 2-4 Optionally, the bracket 21 includes a support column 211 fixedly connected to the inside of the filling barrel 1, and a mounting base 212 provided on one side of the support column 211, with a clamping part 22 provided on the mounting base 212; multiple support columns 211 are provided, and the multiple support columns 211 are distributed at intervals.

[0035] In this embodiment, four support pillars 211 are provided. On the one hand, the four support pillars 211 provide stable support for the mounting base 212. On the other hand, the interval between the support pillars 211 provides a channel for the liquid in the filling tank 1, so that the liquid can enter the liquid extraction pipe 3.

[0036] See Figures 2-4 Optionally, one end of the support column 211 is fixedly connected to the bottom of the inner side of the filling barrel 1, and the top of the support column 211 is 5-10 cm away from the bottom of the inner side of the filling barrel 1.

[0037] In this embodiment, the support column 211 and the inner side of the filling tank 1 are kept at a short distance, for example, 5 cm, 8 cm or 10 cm, which facilitates the liquid to enter the suction pipe 3 and ensures that the suction pipe 3 sucks in as much liquid as possible from the bottom of the filling tank 1.

[0038] See Figures 3-4 Optionally, at least two sets of clamping parts 22 are provided, and the two sets of clamping parts 22 are evenly distributed in a ring around the center of the mounting base 212. The number of grooves 231 is the same as the number of clamping parts 22, and the position distribution of the grooves 231 also corresponds to the clamping parts 22.

[0039] In this embodiment, the clamping part 22 is provided with two sets of mutually symmetrical clamping parts 22. The two sets of clamping parts 22 clamp the mating part 23 in the middle, providing circumferential pressure to the mating part 23, which facilitates fixing the mating part 23 and the liquid extraction tube 3.

[0040] See Figures 3-7 Optionally, the clamping part 22 includes two fixing blocks 221 fixedly connected to the mounting base 212, a fixing shaft 222 fixedly connected between the two fixing blocks 221, a fastener 223 rotatably connected to the fixing shaft 222, and a torsion spring 226 disposed between the fixing shaft 222 and the fastener 223, the torsion spring 226 providing pressure for the fastener 223 to abut against the mating part 23.

[0041] Specifically, when the suction pipe 3 is not installed in the filling tank 1, the bottom of the fasteners 223 on both sides is raised at a certain angle due to the elastic force of the torsion spring 226. When the suction pipe 3 needs to be installed, the suction end of the suction pipe 3 is inserted downward between the two fasteners 223. The end of the suction pipe 3 presses the lower part of the two fasteners 223 downward, and the torsion spring 226 is also pressed simultaneously until the bottom of the fastener 223 is inserted into the groove 231 on the mating part 23. When the operator releases the suction pipe 3, the torsion springs 226 on both fasteners 223 cause the bottom of the fastener 223 to tend to move towards the mating part 23. The cooperation between the fastener 223 and the groove 231 enables the clamping part to fix the mating part 23 and the suction pipe 3 on the bracket 21 inside the filling tank 1.

[0042] See Figures 3-7 Optionally, the fastener 223 includes a transmission plate 224 rotatably connected to the fixed shaft 222, and a clamping plate 225 adjacent to the transmission plate 224; the groove 231 is inclined with a wider top and a narrower bottom, and the two sides of the clamping plate 225 are also inclined to match the inner shape of the groove 231.

[0043] In this embodiment, the inclined design of the groove 231 and the card plate 225 can prevent the liquid extraction pipe 3 from being pulled upward relative to the bracket 21 when the water pump 4 is working.

[0044] See Figures 4-6Optionally, the suction end of the infusion tube 5 is fixedly sleeved with a force-bearing member 51, which includes a force-bearing surface 52. The force-bearing surface 52 is located inside the infusion tube 5 and is designed to be inclined inward.

[0045] In this embodiment, when the water pump 4 starts to draw liquid from the loading tank 1, the liquid enters the suction pipe 3 and impacts the force-bearing surface 52. The force-bearing surface 52 effectively amplifies the upward impact force received by the suction end of the suction end.

[0046] See Figures 3-5 Optionally, pressure strips 232 are provided on both sides of the groove 231, and the two sides of the card plate 225 can abut against the pressure strips 232.

[0047] In this embodiment, the pressure strip 232 is made of elastic rubber material. When the infusion tube 5 is compressed by negative pressure, the rubber is deformed under pressure to fill the gap and presses the inclined surface of the clamping plate 225 in the opposite direction. When the water pump 4 starts to draw liquid from the loading tank 1, the liquid enters the extraction tube 3 and impacts the force-bearing surface 52. The extraction tube 3 is subjected to upward pressure. The pressure strip 232 on the inclined surface of the groove 231 presses the fastener 223 on the bracket 21. Since the fastener 223 is stationary, the pressure strip 232 is deformed under pressure and presses the inclined surface of the clamping plate 225 in the opposite direction, so that the extraction tube 3 can be more firmly installed on the bracket 21.

[0048] See Figures 3-5 Optionally, the mounting base 212 is annular, and the inner side of the mounting base 212 has a space for the mating part 23, which is not constrained by the clamping part 22, to pass through. The part of the mating part 23 with the groove 231 is recessed inward.

[0049] In this embodiment, when the two fasteners 223 are clamped in the groove 231, the inclined side of the groove 231 prevents the mating part 23 from rotating circumferentially and moving upward. The torsion springs 226 on the two fasteners 223 provide clamping force for the mating part 23, which can also effectively prevent the mating part 23 from moving downward. When it is necessary to remove the liquid extraction tube 3, the mating part 23 and the liquid extraction tube 3 are moved downward away from the fasteners 223 together to overcome the clamping force of the two clamping parts 22. Then, the mating part 23 is rotated so that the part of the mating part 23 with two grooves 231 avoids the position of the two fasteners 223. The mating part 23 and the end of the liquid extraction tube 3 are moved away from the loading tank 1 together, and the mating part 23 can be removed from the clamping part 22. The fastening components of this tooling are simple and convenient to install and remove, which further provides convenience for the operator.

[0050] See Figure 1 Optionally, both the infusion tube 5 and the suction tube 3 are fitted with gravity components 6.

[0051] In this embodiment, the gravity component 6 forms a stable "counterweight" in the vertical direction by relying on its own weight, which counteracts the upward bouncing or lateral swinging of the infusion tube 5 and the suction tube 3 at the moment of negative pressure start-up. The range of motion is significantly suppressed, which further facilitates single-person operation by the operator, who does not need to use the other hand to support the infusion tube 5 and the suction tube 3.
