Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic, in particular to a water meter counter capable of removing fog. Background Art

[0002] CN218066621U provides a water meter counter capable of removing fog. It introduces a water meter counter capable of removing fog, including: a transparent cover, which is hermetically connected to the bottom plate; a gear transmission mechanism, located between the upper clamping plate and the lower clamping plate; a word wheel box, located between the upper clamping plate and the lower clamping plate, with word wheels installed inside the word wheel box, and the word wheels are connected to the gear transmission mechanism, and the word wheels are driven to rotate by the gear transmission mechanism; a dial, which is an integral structure with the upper clamping plate, and a direct-reading word wheel group frame corresponding to the word wheels is arranged on the dial; a defogging component, installed on the inner surface of the transparent cover, corresponding to the position of the direct-reading word wheel group frame. Aiming at the problem that fog will be generated inside the transparent cover in the prior art, which affects normal reading, the utility model is provided with a defogging component. When water mist is generated inside the transparent cover, the defogging component can be driven, that is, by magnetic adsorption, by moving the magnetic part externally, the defogger is driven to move, and the fog directly above the direct-reading word wheel group frame is wiped off to ensure normal reading.

[0003] CN212442162U provides a fog removal device for a water meter counter. It proposes a fog removal device for a water meter counter, including a meter body, a counter word wheel is arranged on the upper surface of the meter body, a plastic transparent window is arranged on the meter body, guide rails are arranged on the inner wall of the plastic transparent window, the guide rails are distributed around the counter word wheel, and a slider is slidably installed on the guide rails. The slider is a round cake-shaped rubber structure and internally wraps a magnet sheet. On the inner surface of the plastic transparent window directly above the counter word wheel, guide rails are welded by ultrasonic technology, and sliders wrapped with magnets inside are installed on the guide rails. When there is water mist on the water meter, a magnet can be used outside the plastic transparent window of the water meter to adsorb the slider on the guide rail, and the slider slides along the inner surface of the plastic transparent window, removing the water mist on the plastic transparent window above the counter word wheel.

[0004] For the above two water meter counters capable of removing fog, complex guide rail structures need to be set up, and an external magnet is used to adsorb the internal defogger of the counter to slide and remove water mist, and magnets are arranged in the internal defoggers. For the magnetic part provided in the solution of CN218066621U, it is easy to rust, and rust impurities fall inside the counter, which may affect the internal gear transmission. The solution of CN212442162U has a high cost, and ultrasonic technology is required to weld the guide rails and the plastic transparent window. Summary of the Utility Model

[0026] Embodiment 1

[0027] As Figures 1-5 shown, a fog-removable water meter counter is composed of a pallet 1, a first sealing ring 2, a transparent cover 3, a lower clamping plate 4, a gear transmission assembly 5, an upper clamping plate 6, a character wheel 7, a lever 8, a wiper 9, a second sealing ring 10, a screw 11, and a knob 12. The gear transmission assembly 5 and the character wheel 7 are installed between the upper clamping plate 6 and the lower clamping plate 4. After the upper and lower clamping plates are assembled, they are installed on the pallet 1.

[0028] The transparent cover 3 is provided with a round hole for installing the knob 12. The lower end of the knob 12 is provided with an annular groove, and the upper end is provided with a slotted crosshead. The annular groove is used for installing the second sealing ring, and the slotted crosshead can cooperate with a screwdriver to turn the knob 12.

[0029] The wiping member 9 has a T-shaped structure. One end face of the wiping member 9 is arranged on the dial rod 8. When the dial rod 8 swings, it drives the wiping member 9 to slide in the track 13 of the transparent cover 3, and the wiping member 9 can slide on the dial rod 8. The dial rod 8 and the knob 12 are fixed by screws 11 (M2X7 screws are used in this embodiment), and at the same time, the second sealing ring 10 is compressed and deformed to achieve the sealing function.

[0030] The transparent cover 3 is provided with 3 grooves 14 evenly distributed in the circumferential direction, and the support plate 1 is provided with 3 bosses 15 evenly distributed in the circumferential direction. The assembled transparent cover assembly (transparent cover, wiping member, dial rod, knob, second sealing ring) is clamped and installed on the support plate 1 through the grooves 14 and the bosses 15, and at the same time, the first sealing ring 2 is compressed and deformed to achieve the sealing function.

[0031] The track of the transparent cover 3 is arranged directly above the word wheel 7 and has an L-shaped structure. When the wiping member 9 does not need to work, the wiping member 9 stays in the track area beside the word wheel 7, without affecting the word wheel reading.

[0032] When there is water mist inside the counter affecting the reading, use a flat-blade screwdriver to turn the flat slot at the upper end of the knob 12, drive the dial rod 8 to rotate around the knob 12, and at the same time drive the wiping member 9 to wipe the water mist in the track of the transparent cover 3 to achieve the defogging function.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
