[0002] A flow meter is an instrument designed to measure the flow rate of a fluid (liquid or gas) in a pipe or open channel. Flow meters are widely used in industry. They are mainly used to measure the flow rate of fluids (including gases, liquids and suspended particles) flowing through pipes or channels.

[0003] Depending on the usage requirements, some flow meters will be installed on outdoor pipes. In order to prevent the flow meter head from being damaged by outdoor external factors and to prevent irrelevant personnel from operating the flow meter, existing flow meters are usually installed with a protective shell outside the head, and the protective shell is usually provided with an observation glass for technicians to observe data.

[0004] Although there are usually air holes on the protective shell, the inside of the protective shell is a relatively closed environment relative to the outside world, and the air circulation is poor. In a relatively humid and hot environment, water mist will condense on the display screen and observation glass of the flow meter head, resulting in the technicians being unable to intuitively observe the data displayed on the meter head. They need to open the protective shell and wipe off the water mist before they can observe, which makes the observation operation inconvenient.

[0005] Therefore, how to more conveniently wipe off the water mist on the observation glass and the meter head to facilitate technicians to observe data has become a problem that needs to be solved urgently. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example:

[0034] like Figures 1 to 5 As shown, a flow meter with a protective structure includes a flow meter body 11, the flow meter body 11 includes a meter head 12, a mounting base 31 is fixedly connected to the flow meter body 11, a protective shell 13 is detachably mounted on the mounting base 31, a threaded hole 32 is opened at the lower end of the protective shell 13, an external hexagonal screw 38 is arranged on the mounting base 31, and the external hexagonal screw 38 is threadedly connected in the threaded hole 32. When the technician needs to inspect the meter head 12, the protective shell 13 can be removed by loosening the external hexagonal screw 38 with a wrench to expose the meter head 12, and the meter head 12 can be inspected and maintained.

[0035] A protective cavity 14 is defined in the protective shell 13, the meter head 12 is located in the protective cavity 14, a movable door 15 is hinged on the protective shell 13, an observation glass 16 for observing the meter head 12 is mounted on the movable door 15, a cleaning rod 17 is slidably disposed in the protective cavity 14, a wiping sponge 18 is fixedly connected to the cleaning rod 17, the cleaning rod 17 is located between the meter head 12 and the observation glass 16, and a locking mechanism for fixing the cleaning rod 17 is symmetrically disposed in the protective cavity 14.

[0036] The working principle of the utility model is as follows: when water mist condenses on the instrument panel of the meter head 12 or the observation glass 16, the technician can use the cleaning rod 17 to drag up and down to make the wiping sponge 18 wipe off the water mist, so that the technician can wipe off the water mist on the instrument panel of the meter head 12 and the inner wall of the observation glass 16 without opening the movable door 15, so that the technician can observe the data more conveniently;

[0037] After wiping, the technician can push the cleaning rod 17 up or down to make it close to the locking mechanism, and fix the position of the cleaning rod 17 by the locking mechanism, so as to prevent the cleaning rod 17 from blocking the instrument panel of the meter head 12, so as to facilitate the technician to read the readings.

[0038] The protective shell 13 is provided with a sliding groove 19 on one side of the protective cavity 14, and the cleaning rod 17 includes a sliding rod 20, and the sliding rod 20 is slidably connected in the sliding groove 19, and a groove 21 is penetrated through the front side of the sliding rod 20, and a lever 22 is fixedly connected to the front side of the sliding rod 20, and the lever 22 is slidably connected in the groove 21. In addition, the protective shell 13 is provided with a liquid supply component on one side of the sliding groove 19, and the technician injects alcohol or other cleaning agents into the wiping sponge 18 through the liquid supply component.

[0039] The liquid supply assembly includes a plug 23, and the specific connection method of the plug 23 is as follows: a plug hole 24 is opened on the side of the sliding groove 19 away from the protection cavity 14, and the plug 23 is inserted into the plug hole 24 by friction, and a liquid supply tube 25 is installed in the wiping sponge 18, one end of the liquid supply tube 25 passes through the sliding rod 20, and a plurality of leakage holes 26 are opened on one end of the liquid supply tube 25 located in the wiping sponge 18;

[0040] In addition, a mounting groove 27 is provided in the central axis direction of the plug 23 , and a one-way valve 39 is installed in the mounting groove 27 .

[0041] The working principle of the liquid supply component is: the technician first fixes the cleaning rod 17 to the upper magnetic seat 28 to align the liquid supply tube 25 with the one-way valve 39. The technician can insert a needle or other tool into the upper section 37 and inject alcohol or other cleaning agents into the liquid supply tube 25. The cleaning agent penetrates into the wiping sponge 18 through the leakage hole 26 and soaks the wiping sponge 18. The wiping sponge 18 soaked with the cleaning agent can not only remove water mist, but also wipe off the dust attached to the observation glass 16 and the instrument of the meter head 12, thereby further ensuring that the technician can intuitively observe the data displayed on the meter head 12.

[0042] The locking mechanism includes an upper magnetic seat 28 and a lower magnetic seat 33, and the specific structure of the locking mechanism is: the upper magnetic seat 28 is fixedly connected to the top of the protective cavity 14, and the lower magnetic seat 33 is fixedly connected to the upper end of the mounting base 31 and extends into the protective cavity 14, and the upper magnetic seat 28 and the lower magnetic seat 33 are both fixedly connected with permanent magnets 29, and the upper and lower ends of the cleaning rod 17 are provided with metal blocks 30, and the metal block 30 is adsorbed on the permanent magnet 29 by magnetic force.

[0043] Through the above structure, the cleaning rod 17 is fixed to the locking mechanism by magnetic adsorption, so as to prevent the cleaning rod 17 from sliding onto the observation glass 16 and blocking the meter head 12 when the cleaning rod 17 is installed horizontally or tilted, thereby interfering with the technician's observation of data.

[0044] It should be noted here that the surface of the flow meter body 11 is provided with an anti-magnetic coating (not shown in the figure), so the magnetism of the permanent magnet 29 will not affect the normal operation of the flow meter body 11.

[0045] In addition, a plurality of air holes 34 communicating with the protective cavity 14 are provided on the side wall of the protective shell 13. The air holes 34 can promote the circulation of air in the protective cavity 14 and the outside air, thereby avoiding and alleviating the stuffiness in the protective cavity 14, which is not only beneficial to the heat dissipation of the meter head 12, but also can effectively alleviate the condensation of water mist.

[0046] Furthermore, the air vent 34 includes a lower section 35, an inclined section 36 and an upper section 37. The inclined section 36 is located between the lower section 35 and the inclined section 36 and is inclined upward. Through the above structure, it is possible to effectively prevent rainwater from entering the protective cavity 14 through the air vent 34 when it rains, thereby increasing the ambient humidity in the protective cavity 14, and prevent the outer shell of the meter head 12 from aging and rusting due to rain.

[0047] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
