Description

Technical Field

[0001] The utility model relates to the technical field of volumetric flowmeters, in particular to a three-rotor flowmeter with a sunshade. Background Art

[0002] A three-rotor flowmeter is a positive displacement flowmeter that continuously measures the flow rate of liquids in closed pipes. It combines the high accuracy of positive displacement flowmeters with low rotor mechanical friction, a long service life, and strong adaptability to viscosity changes.

[0003] Existing three-rotor flowmeters installed outdoors are usually equipped with sun visors. Such sun visors are generally fixed directly on the converter of the three-rotor flowmeter through a clamp to prevent direct sunlight from shining on the converter. However, when the converter needs to be disassembled for inspection, it is necessary to first remove the sun visor from the converter, and then disassemble the converter. The disassembly and assembly process is relatively cumbersome. Secondly, such sun visors can usually only block the top of the converter. Although it is convenient for daily inspections and observations, and for recording the readings on the converter display, the sun shading effect is poor because there is no enclosure or side panel to block the four sides of the converter.

[0038] like Figure 1-12 As shown, in one embodiment of the present invention, a three-rotor flowmeter with a sunshade is provided, comprising a flowmeter body 10, a mounting bracket 20, an outer cover 30, a first locking assembly 40, a baffle 50, and a second locking assembly 60. A detachable converter 11 is mounted on the top of the flowmeter body 10, and the mounting bracket 20 is fixed to the flowmeter body 10. The outer cover 30 is hinged on the mounting bracket 20, and the outer cover 30 can cover or expose the converter 11. The front side of the outer cover 30 is provided with an observation port 31 for observing the display screen of the converter 11. The first locking assembly 40 can lock the outer cover 30 on the mounting bracket 20 after the outer cover 30 covers the converter 11. The baffle 50 is hinged on the outer cover 30, and the baffle 50 is used to cover or open the observation port 31. The second locking assembly 60 can lock the baffle 50 on the outer cover 30 to keep the baffle 50 blocking the observation port 31 , or release the locking state of the baffle 50 to open the observation port 31 .

[0039] This embodiment discloses a three-rotor flowmeter with a sunshade. With the outer cover 30 covering the converter 11 and the baffle 50 shielding the observation port 31, this prevents direct sunlight from reaching the converter 11. This physical isolation reduces heat radiation, allowing the electronic components within the converter 11 to operate at a suitable temperature and slowing down the aging of materials such as the converter 11's housing and seals. Furthermore, the design of the first locking assembly 40 and the second locking assembly 60 securely locks the outer cover 30 and baffle 50, preventing them from being blown by strong winds and improving their stability.

[0040] See Figure 9 After the inspection personnel release the locking state of the outer cover 30 by the first locking assembly 40, they can rotate the outer cover 30 to expose the converter 11. In this way, the inspection personnel can regularly remove the converter 11 for inspection without having to disassemble the mounting frame 20 and the outer cover 30 as a whole, which facilitates the disassembly and assembly of the converter 11.

[0041] See Figure 1After the inspection personnel release the locking state of the baffle 50 by the second locking assembly 60, they can rotate the baffle 50 to open the observation port 31, thereby facilitating the observation and recording of the data on the display screen of the converter 11. In this way, there is no need to operate the first locking assembly 40 to unlock and rotate the outer cover 30 as a whole, making the operation more convenient.

[0042] See Figure 3-5 as well as Figure 12 In one embodiment, the second locking assembly 60 includes a handle 61, a locking rod 62, and a stopper 63. The handle 61 is rotatably mounted on the baffle 50, and the locking rod 62 is mounted on the handle 61 and located inside the baffle 50. The stopper 63 is fixed to the side panel 32 of the outer cover 30 and positioned between the locking rod 62 and the baffle 50. The stopper 63 blocks the locking rod 62, thereby preventing the baffle 50 from swinging about the hinge center, thereby maintaining the baffle 50 in a state of blocking the observation port 31. When the locking rod 62 is blocked by the stopper 63, the baffle 50 cannot rotate, thereby maintaining the baffle 50 in a state of blocking the observation port 31. After turning the handle 61, the handle 61 will synchronously drive the locking rod 62 to swing, so that the locking rod 62 avoids the limit block 63. In this way, the locking state of the baffle 50 can be released, so that the observation port 31 can be opened, making it convenient for inspection personnel to observe and record the data on the display screen of the converter 11. The overall structure is simple and easy to operate.

[0043] Furthermore, the second locking assembly 60 includes a first limit pin 64 and a second limit pin 65, both of which are fixed to the inner sidewall of the baffle 50. When the locking rod 62 rests on the first limit pin 64, it is blocked by the limit block 63. The locking rod 62 can only swing between the first limit pin 64 and the second limit pin 65. When the locking rod 62 abuts the second limit pin 65, the locking rod 62 has cleared the limit block 63. The design of the first limit pin 64 and the second limit pin 65 limits the swing range of the locking rod 62, thereby facilitating the operation of locking or unlocking the baffle 50 by operating the handle 61.

[0044] See Figure 11 In one embodiment, the outer cover 30 includes two parallel side panels 32, one of which is provided with a locking hole 321. The first locking assembly 40 includes a locking bolt 41, which is threadedly engaged with the mounting bracket 20 and can extend into the locking hole 321. The first locking assembly 40 also includes a first support block 42 fixed to the mounting bracket 20. The first support block 42 is fixed with a nut 43, and the locking bolt 41 is threadedly engaged with the nut 43.

[0045] When the outer cover 30 is covering the converter 11, the locking bolt 41 is rotated so that it extends into the locking hole 321. This locks the outer cover 30 to the mounting bracket 20, thereby preventing the outer cover 30 from rotating. After the locking bolt 41 is removed from the locking hole 321, the operator can rotate the outer cover 30, thereby facilitating the removal of the converter 11.

[0046] Although rotating the outer cover 30 can also reveal the display screen of the converter 11, the operation of rotating the outer cover 30 requires first operating the locking bolt 41 to withdraw from the lock hole 321 and then rotating the outer cover 30 as a whole. Therefore, the operation of rotating the outer cover 30 is more complicated than rotating the baffle 50. Therefore, by designing the baffle 50 to cover the observation port 31, it is possible to more conveniently observe and record the data on the display screen of the converter 11.

[0047] In one embodiment, the mounting bracket 20 includes two hoops 21 and two support arms 22. Each hoops 21 is connected to a corresponding support arm 22. The outer cover 30 is hingedly connected to each support arm 22, and each side panel 32 can be placed on a corresponding support arm 22. The mounting bracket 20 is fixed to the flowmeter body 10 through the connection between the two hoops 21. When the side panels 32 are placed on the support arms 22, the outer cover 30 covers the converter 11, and the support arms 22 can provide stable support for the outer cover 30.

[0048] In one embodiment, the housing 30 further includes a top plate 33, which is connected to the two side plates 32. Second support blocks 23 are provided on the support arms 22. After the housing 30 is rotated to expose the converter 11, the top plate 33 rests on the two second support blocks 23. The design of the second support blocks 23 also provides stable support for the housing 30.

[0049] In one embodiment, the housing 30 further includes a rear panel 34, which is connected to the top panel 33 and the two side panels 32. Louvers 35 are provided on the rear panel 34 and the side panels 32. The design of the louvers 35 can enhance air convection, thereby enabling the converter 11 to operate in a suitable temperature environment.

[0050] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
