Description

Technical Field

[0001] The utility model relates to the technical field of vertical screw wing water meters, and particularly to a vertical screw wing water meter for a sprinkler truck. Background Technique

[0002] A water meter is an instrument for measuring water flow, mostly for measuring the cumulative water flow. Generally, it is divided into two categories: volumetric water meters and velocity water meters. It originated in the UK, and the development of water meters has a history of nearly two hundred years. When selecting the specification of a water meter, the size and flow range of the water flow used under normal circumstances should be estimated first, and then the water meter with the specification whose normal flow is closest to this value should be selected as the first choice.

[0003] However, in the prior art, the water surface installed on the surface of the existing sprinkler truck is relatively simple. After a long time of use, dust and stains are likely to appear on its surface, so it is inconvenient for the staff to observe the display on the water surface. Even if there is a dust-proof cover on the top of the traditional water meter, it is inconvenient to disassemble when the surface of the water meter needs to be cleaned.

[0004] Therefore, we need a vertical screw wing water meter for a sprinkler truck to solve the problem of dust prevention of the top cover of the existing vertical screw wing water meter, and it can also realize the disassembly of the dust-proof cover on the top of the vertical screw wing water meter. Content of the Utility Model

[0005] The purpose of the utility model is to provide a vertical screw wing water meter for a sprinkler truck to solve the problem of dust prevention of the top cover of the existing vertical screw wing water meter proposed in the above background technique, and it can also realize the disassembly of the dust-proof cover on the top of the vertical screw wing water meter.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A vertical screw wing water meter for a sprinkler truck, including a vertical screw wing water meter body. An inner sleeve ring is sleeved on the outer surface of the vertical screw wing water meter body. An outer sleeve ring is arranged on the surface of the inner sleeve ring. The outer surface of the outer sleeve ring is fixedly connected to the surface of a vertical block. The surface of the vertical block is rotationally connected to the surface of a rotating shaft through a through hole. The end of the rotating shaft is fixedly connected between the two side plates of a hinge block. The top surface of the hinge block is fixedly connected to the bottom surface of a dust-proof cover.

[0007] Preferably, the outer surface of the inner sleeve ring is clamped to the surface of a limiting annular groove. The limiting annular groove is arranged on the inner ring surface of the outer sleeve ring. A spring groove is opened inside the inner sleeve ring. A spring is arranged on the surface of the spring groove. The end of the spring abuts against the surface of an arc-shaped clamping block. The surface of the arc-shaped clamping block is movably connected to the surface of the spring groove. The surface of the arc-shaped clamping block is inserted into the surface of an arc-shaped clamping groove. The arc-shaped clamping groove is opened on the surface of the vertical screw wing water meter body.

[0008] Preferably, the number of the arc-shaped clamping grooves is two, and the two arc-shaped clamping grooves are symmetrically arranged along the center point of the vertical screw wing water meter body.

[0009] Preferably, a bearing fixing hole is formed in the top surface of the dust-proof cover. The bottom bearing surface of the limit rotating pin is fixedly connected to the surface of the bearing fixing hole. The surface of the limit rotating pin is rotatably connected to the surface of the through hole of the buckle plate. The top surface of the anti-slip gasket is fixedly connected to the bottom surface of the buckle plate. A hook opening is formed in the top surface of the buckle plate, and the surface of the hook opening is clamped to the surface of the locking hook. The outer ring surface of the outer sleeve ring is fixedly connected to the end of the locking hook.

[0010] Preferably, a transparent observation window is provided on the top surface of the dust-proof cover.

[0011] Preferably, the central points of the outer sleeve ring, the dust-proof cover and the inner sleeve ring are located on the same vertical line.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The dust-proof cover can be flipped to prevent dust on the top surface of the vertical screw wing water meter body. It is convenient to open the dust-proof cover to observe the display of the dust-proof cover. When the outer sleeve ring is lifted upward, the inner sleeve ring and the vertical screw wing water meter body can be disassembled and separated. When the buckle plate is rotated so that the hook opening on its top surface is clamped to the surface of the locking hook, the dust-proof cover is firmly locked on the top surface of the vertical screw wing water meter body and cannot be opened, avoiding the dust-proof cover being opened due to the movement and vibration of the sprinkler truck; further solving the problem of dust-proofing the top cover of the existing vertical screw wing water meter, and also realizing the disassembly of the dust-proof cover on the top of the vertical screw wing water meter.

Specific Embodiments

[0020] In order to clearly and completely describe the objectives, technical solutions of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present utility model, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution: a vertical screw-wing water meter for a sprinkler truck, including a vertical screw-wing water meter body 1. An inner sleeve ring 10 is sleeved on the outer surface of the vertical screw-wing water meter body 1. An outer sleeve ring 2 is arranged on the surface of the inner sleeve ring 10. The outer surface of the outer sleeve ring 2 is fixedly connected to the surface of a vertical block 6. The surface of the vertical block 6 is rotatably connected to the surface of a rotating shaft 5 through a through hole. The end of the rotating shaft 5 is fixedly connected between the two side plates of a hinge block 4. The top surface of the hinge block 4 is fixedly connected to the bottom surface of a dust-proof cover 3. By sleeving the surface of the inner sleeve ring 10 on the surface of the vertical screw-wing water meter body 1 and then arranging the outer sleeve ring 2 on the surface of the inner sleeve ring 10, the connection between the outer sleeve ring 2 and the inner sleeve ring 10 is realized. By rotatably connecting the surface of the rotating shaft 5 to the inside of the vertical block 6, then fixedly connecting the end of the rotating shaft 5 between the two side plates of the hinge block 4, and fixedly connecting the top surface of the hinge block 4 to the bottom surface of the dust-proof cover 3, the dust-proof cover 3 can be flipped to prevent dust on the top surface of the vertical screw-wing water meter body 1.

[0023] Embodiment 2

[0024] Referring to the attached Figures 1 to 6 , on the basis of Embodiment 1, in order to facilitate opening the dust-proof cover 3 to observe the display of the dust-proof cover 3, the outer surface of the inner sleeve ring 10 is clamped to the surface of a limit annular groove 11, and the limit annular groove 11 is arranged on the inner ring surface of the outer sleeve ring 2. A spring groove 9 is opened inside the inner sleeve ring 10. A spring 12 is arranged on the surface of the spring groove 9. The end of the spring 12 abuts against the surface of an arc-shaped clamping block 8. The surface of the arc-shaped clamping block 8 is movably connected to the surface of the spring groove 9. The surface of the arc-shaped clamping block 8 is inserted into the surface of an arc-shaped clamping groove 7, and the arc-shaped clamping groove 7 is opened on the surface of the vertical screw-wing water meter body 1;

[0025] The elastic force of the spring 12 inside the spring groove 9 pushes the arc-shaped clamping block 8 to move inside it. By setting the arc-shaped clamping groove 7 on the surface of the vertical vane water meter body 1, when the inner sleeve ring 10 is sleeved on the surface of the vertical vane water meter body 1, the spring groove 9 is thus oppositely clamped to the surface of the arc-shaped clamping groove 7. Therefore, the inner sleeve ring 10 is firmly sleeved on the surface of the vertical vane water meter body 1. By clamping the surface of the inner sleeve ring 10 to the surface of the limiting annular groove 11, the outer sleeve ring 2 is firmly installed on the surface of the inner sleeve ring 10. At the same time, the dust-proof cover 3 can rotate on the surface of the vertical vane water meter body 1 following the outer sleeve ring 2, facilitating the opening of the dust-proof cover 3 to observe the display of the dust-proof cover 3. When the outer sleeve ring 2 is lifted upward, the inner sleeve ring 10 and the vertical vane water meter body 1 can be disassembled and separated from each other.

[0026] Embodiment 3

[0027] Refer to the appendix Figures 1 to 6 , on the basis of Embodiment 2, in order to avoid the dust-proof cover 3 being opened due to the movement and vibration of the sprinkler truck, a bearing fixing hole 17 is opened on the top surface of the dust-proof cover 3. The bottom bearing surface of the limiting rotating pin 14 is fixedly connected to the surface of the bearing fixing hole 17. The through-hole surface of the clamping plate 15 is rotatably connected to the surface of the limiting rotating pin 14. The top surface of the anti-slip gasket 16 is fixedly connected to the bottom surface of the clamping plate 15. A hook opening 18 is opened on the top surface of the clamping plate 15. The surface of the hook opening 18 is clamped to the surface of the locking hook 13. The end of the locking hook 13 is fixedly connected to the outer ring surface of the outer sleeve ring 2;

[0028] By rotatably connecting the surface of the limiting rotating pin 14 to the inside of the clamping plate 15, when the clamping plate 15 is rotated so that the hook opening 18 on its top surface is clamped to the surface of the locking hook 13, the dust-proof cover 3 is thus firmly locked on the top surface of the vertical vane water meter body 1 and cannot be opened, avoiding the dust-proof cover 3 being opened due to the movement and vibration of the sprinkler truck. By fixedly connecting the bottom bearing surface of the limiting rotating pin 14 to the inside of the bearing fixing hole 17, the limiting rotating pin 14 is installed on the top surface of the dust-proof cover 3 to play a limiting role on the clamping plate 15.

[0029] In actual use, the surface of the inner sleeve ring 10 is sleeved on the surface of the vertical screw wing water meter body 1, and then the outer sleeve ring 2 is arranged on the surface of the inner sleeve ring 10, so that the outer sleeve ring 2 and the inner sleeve ring 10 are connected. The surface of the rotating shaft 5 is rotationally connected to the inside of the vertical block 6, and then the end of the rotating shaft 5 is fixedly connected between the two side plates of the hinge block 4. The top surface of the hinge block 4 is fixedly connected to the bottom surface of the dust-proof cover 3, so that the dust-proof cover 3 can be turned over to prevent dust on the top surface of the vertical screw wing water meter body 1. The elastic force of the spring 12 in the spring groove 9 pushes the arc-shaped clamping block 8 to move inside it. By arranging an arc-shaped clamping groove 7 on the surface of the vertical screw wing water meter body 1, when the inner sleeve ring 10 is sleeved on the surface of the vertical screw wing water meter body 1, the spring groove 9 is moved and clamped to the surface of the arc-shaped clamping groove 7, so that the inner sleeve ring 10 is firmly sleeved on the surface of the vertical screw wing water meter body 1. By clamping the surface of the inner sleeve ring 10 to the surface of the limiting annular groove 11, the outer sleeve ring 2 is firmly installed on the surface of the inner sleeve ring 10. At the same time, the dust-proof cover 3 can rotate on the surface of the vertical screw wing water meter body 1 along with the outer sleeve ring 2, which is convenient to open the dust-proof cover 3 to observe the display of the dust-proof cover 3. By pulling up the outer sleeve ring 2, the inner sleeve ring 10 and the vertical screw wing water meter body 1 can be disassembled and separated. The surface of the limiting rotating pin 14 is rotationally connected to the inside of the clamping plate 15. When the clamping plate 15 is rotated so that the hook opening 18 on its top surface is clamped on the surface of the locking hook 13, the dust-proof cover 3 is firmly locked on the top surface of the vertical screw wing water meter body 1 and cannot be opened, avoiding the dust-proof cover 3 being opened due to the movement and vibration of the sprinkler truck. By fixedly connecting the bottom bearing surface of the limiting rotating pin 14 to the inside of the bearing fixing hole 17, the limiting rotating pin 14 is installed on the top surface of the dust-proof cover 3 to play a limiting role on the clamping plate 15.
