[0033] A transfer threaded tube 3 is installed on the connecting plate 1 through the clamping member 29;

[0034] A support frame 4 is erected on the top end of the connecting plate 1. A guiding support 5 is installed on the support frame 4. A guiding hole 501 is opened at the end of the guiding support 5 extending into the through - hole 101. A guide rod 6 is slidably installed in the guiding hole 501. A hollow floating ball 7 is fixedly installed at the bottom end of the guide rod 6. A metering assembly 8 is installed on the support frame 4.

[0035] Wherein, the clamping member 29 includes an L - shaped slider 291. The L - shaped slider 291 is slidably installed in the groove 102, and the L - shaped slider 291 is provided with a threaded hole threadedly connected to the lead screw 27. A supporting and clamping block 292 is installed on the bottom side wall of the L - shaped slider 291. A screw rod 293 is installed at the bottom end of the L - shaped slider 291. A bottom plate 294 is threadedly installed on the screw rod 293.

[0036] It should be noted that: during use, select the adapter threaded pipe 3 that fits the threaded size of the mouth of the open can. When the mouth interface of the can is an internal thread (the adapter threaded pipe 3 is an external threaded pipe), install the support clamp block 292 on the outer side wall of the L-shaped slider 291, and then place the adapter threaded pipe 3 on the outer side of several L-shaped sliders 291. Rotate the handwheel 25 to drive the worm 24 to rotate. The worm 24 meshes with the worm wheel 23 to drive the hollow pipe 22 to rotate. The driving bevel gear 26 rotates synchronously with the hollow pipe 22 and drives the lead screw 27 to rotate synchronously by meshing with the driven bevel gear 28. When rotating, drive the L-shaped slider 291 to slide along the groove 102 until the adapter threaded pipe 3 is internally supported and fixed by the support clamp block 292. Then, screw the bottom plate 294 to drive the top end of the adapter threaded pipe 3 to squeeze and contact the bottom end of the connecting plate 1. After installation, the connecting plate 1, the guide rod 6 and the hollow float 7 on the connecting plate 1 can be installed on the open can through the adapter threaded pipe 3, and then the metering component 8 is used in cooperation with the observation magnifying glass 91 to realize the real-time liquid level observation of the open can;

[0037] When the mouth interface of the can is an external thread (the adapter threaded pipe 3 is an internal threaded pipe), install the support clamp block 292 on the inner side wall of the L-shaped slider 291, and then place the adapter threaded pipe 3 on the inner side of several L-shaped sliders 291. Reverse the handwheel 25 to realize external clamping, and then screw the bottom plate 294 to fix it.

[0038] In an embodiment of the present invention, please refer to Figures 1 to 8 The top end of the adapter threaded pipe 3 is provided with an installation groove, and a sealing ring 31 is embedded in the installation groove.

[0039] It should be noted that: in this way, when the adapter threaded pipe 3 is squeezed against the bottom end of the connecting plate 1 by the bottom plate 294, the sealing ring 31 is used to realize pressing and sealing.

[0040] It should also be noted that: here, in order to maintain the sealing performance of the connection, the sealing performance between the L-shaped slider 291 and the groove 102 is sealed by sleeving a seal on the outer side of the sliding part of the L-shaped slider 291 and the groove 102 to improve the sealing performance of the groove 102, and the lead screw 27 is a tubular thread to realize thread sealing.

[0041] In an embodiment of the present invention, please refer to Figures 1 to 8 The metering component 8 includes an automatic retractable tape measure 81. The automatic retractable tape measure 81 is fixedly installed on the support frame 4, and the front end of the tape of the automatic retractable tape measure 81 is fixedly connected with an adapter belt 83. A guide wheel 82 is installed on one side of the support frame 4 away from the observation magnifying glass 91. The front end of the adapter belt 83 bypasses the guide wheel 82 and is fixedly connected with one side of the guide rod 6. An indicating arrow 84 is installed on one side of the support frame 4 facing the observation magnifying glass 91;

[0042] It should be noted that when the metering component 8 is in use, after the transfer belt 83 is connected to the top of the guide rod 6 and inserted into the open-top tank, when the liquid level rises, the hollow float ball 7 drives the guide rod 6 to slide upward along the guide hole 501, so as to pull the tape of the automatic retractable tape measure 81 to move synchronously through the transfer belt 83. When the liquid level drops, the guide rod 6 drops synchronously, and the automatic retractable tape measure 81 retracts synchronously. Then, the scale of the tape corresponding to the indicating arrow 84 is observed through the observation magnifying glass 91 for metering observation;

[0043] In this embodiment: The guide rod 6 is in sliding fit with the guide wheel 82. Here, in order to convert the movement of the guide rod 6 into the contraction amount of the tape of the automatic retractable tape measure 81 equivalently, one end of the guide rod 6 connected with the transfer belt 83 just adheres to the middle part of the rotation of the guide wheel 82. Thus, when moving, the transfer belt 83 and the tape are synchronously driven to move vertically upward along the guiding middle part of the guide wheel 82, so as to realize the observation of the movement of the guide rod 6 by observing the extension and retraction of the tape, and further realize the liquid level observation.

[0044] It should also be noted that: In order to enable the guide rod 6 to move vertically, its cross-section is rectangular. Thus, under the guidance of the guide hole 501, the guide rod 6 only moves in the vertical direction, so as to avoid the rotation causing the deviation of the tape and affecting the accurate observation of the liquid level.

[0045] Embodiment 2:

[0046] On the basis of Embodiment 1, please refer to Figure 1 and Figure 8 , a flange 32 is detachably installed at the bottom end of the adapter threaded pipe 3 by screws;

[0047] It should be noted that: In this way, when the interface of the open-top tank is flange-connected, only the corresponding flange 32 needs to be installed at the bottom end of the adapter threaded pipe 3 to achieve quick docking installation, further improving the applicable range.

[0048] The working principle of the quick-installation floating ball metering device for the open-top tank provided by the present utility model is as follows:

[0049] In use, select the adapter threaded pipe 3 that fits the threaded size of the opening of the open can. When the can opening interface is an internal thread (the adapter threaded pipe 3 is an external threaded pipe), install the support clamp block 292 on the outer side wall of the L-shaped slider 291. Then place the adapter threaded pipe 3 outside several L-shaped sliders 291. Rotate the handwheel 25 to drive the worm 24 to rotate. The worm 24 meshes with the worm gear 23 to drive the hollow pipe 22 to rotate. The driving bevel gear 26 rotates synchronously with the hollow pipe 22 and drives the lead screw 27 to rotate synchronously by meshing with the driven bevel gear 28. When rotating, it drives the L-shaped slider 291 to slide along the groove 102 until the adapter threaded pipe 3 is internally supported and fixed by the support clamp block 292. Then screw the bottom plate 294 to drive the top end of the adapter threaded pipe 3 to squeeze and contact the bottom end of the connecting plate 1. After installation, the connecting plate 1, the guide rod 6 and the hollow float 7 on the connecting plate 1 can be installed on the open can through the adapter threaded pipe 3. Then, the metering assembly 8 is used in cooperation with the observation magnifying glass 91 to realize the real-time liquid level observation of the open can. When the metering assembly 8 observes, when the liquid level rises, the guide rod 6 is driven by the hollow float 7 to slide upward along the guide hole 501, so as to drive the tape of the automatic retractable tape measure 81 to move synchronously through the transfer belt 83. When the liquid level drops, the guide rod 6 drops synchronously and the automatic retractable tape measure 81 retracts synchronously. Then, the tape scale corresponding to the indicating arrow 84 is observed through the observation magnifying glass 91 for metering observation;

[0050] Further, when the interface of the open can is a flange connection, only need to install the corresponding flange 32 at the bottom end of the adapter threaded pipe 3.

[0051] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
