Description

Technical Field

[0001] The present invention relates to the technical field of water meter anti-freezing, and particularly to a wet water meter movement with anti-freezing function. Background Art

[0002] Water meters are essential equipment for every household in modern life. The key component for metering in a water meter is the water meter movement. Usually, the water meter movement is a wet water meter movement, which is often immersed in water during use.

[0003] However, during the use of a general wet water meter movement, when the weather is cold in winter and the water freezes, the watch glass on the top of the movement is often damaged due to the volume expansion of the frozen water. Therefore, how to achieve the anti-freezing of the wet water meter movement has become a technical problem to be solved. Summary of the Invention

[0004] The purpose of the present invention is to provide a wet water meter movement with anti-freezing function to overcome the defects existing in the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A wet water meter movement with anti-freezing function, wherein the water meter movement includes a measuring component and a counter component fixed by interference fit; the counter component includes a gear box; an upper clamping plate, a lower clamping plate and a gear set are arranged in the gear box; the upper clamping plate and the lower clamping plate are fixed in the gear box by bolts; the gear set is arranged in the gear box and is composed of a plurality of meshing gears; the gear set is connected with a pointer by interference fit; the upper clamping plate is an imitation fully liquid-sealed clamping plate, and a counterbore is arranged thereon; the pointer is arranged in the counterbore; a plurality of positioning holes are arranged on both the upper clamping plate and the lower clamping plate; the gear set is positioned and connected through the positioning holes at the upper and lower ends; positioning grooves are also arranged on the upper clamping plate and the lower clamping plate; a numeral wheel window is positioned and installed in the positioning grooves.

[0007] Further, the measuring component includes a filter screen, an impeller box and an impeller; the filter screen and the impeller box are connected by interference fit; the impeller is arranged in the impeller box; the top of the impeller passes through the impeller box and the wheel box and is meshed with the gear set; the lower end of the gear box and the upper end of the impeller box are fixed by interference fit.

[0008] Further, a first installation groove is arranged at the bottom of the filter screen; the first installation groove is filled with a first sponge filler.

[0009] Further, a plurality of second installation grooves are arranged on the upper clamping plate; a plurality of third installation grooves are arranged on the lower clamping plate; the second installation grooves and the third installation grooves are both filled with a second sponge filler.

[0010] Further, a third sponge filler is filled between the lower clamping plate and the gear box.

[0011] Further, the water meter movement is arranged on the watch case; a watch cover is arranged on the water meter movement; a watch glass is arranged between the top of the water meter movement and the watch cover; the watch glass is pressed above the upper clamping plate.

[0012] Further, a waterproof gasket is also arranged between the water meter movement and the watch cover.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) Through the imitation of the upper clamping plate of the fully liquid-sealed type, a counterbore is arranged thereon for installing the pointer. When the water meter movement is installed, the upper panel of the upper clamping plate will closely adhere to the watch glass, and water will stay in the counterbore where the pointer is located and will not spread under the entire watch glass. In this way, the contact area between water and the watch glass is greatly reduced. When freezing causes the water pressure to rise, it can relieve the pressure on the watch glass to a certain extent, thereby achieving the purpose of anti-freezing, preventing the watch glass from being damaged, and thus reducing the maintenance cost.

[0015] (2) Through the design of the first installation groove, the second installation groove and the third installation groove, sponge fillers are arranged in each installation groove, and the compressible sponge is used to further offset the pressure, improve the anti-freezing effect, and further reduce the damage risk of the watch glass and the water meter movement.
