Description

Technical Field

[0001] The utility model relates to the field of auxiliary instruments for nuclear power plants, in particular to a Rosemount transmitter cover opening tool. Background Art

[0002] A transmitter is a device that converts one type of signal into another and is commonly used in measurement and control systems. Transmitters play a vital role in industrial automation, process control, and data acquisition. Depending on the physical quantity being measured, transmitters can be categorized into the following types: temperature transmitters, flow transmitters, displacement transmitters, and level transmitters.

[0003] Rosemount, a major transmitter manufacturer, produces transmitters widely used at a domestic nuclear power plant site. Models include the 3051 series, 1154 series, and 1152 series. To ensure equipment stability and reliability, instruments must be regularly calibrated. This process involves removing the transmitter cover. Due to the instrument's waterproof rating, the cover generally has torque requirements, making it difficult to open directly by hand during on-site maintenance and inconvenient for on-site inspections. Traditional cover removal methods often rely on general-purpose tools such as screwdrivers or wrenches, which are not only inconvenient to operate but also prone to damage to the cover and transmitter body. Therefore, developing a cover removal tool specifically for Rosemount transmitters is particularly important. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0029] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0030] like Figure 1-Figure 3 As shown, the Rosemount transmitter cover opening tool of the present invention includes a rotating handle 10 and a cover opening cover 20 connected to the rotating handle 10. The cover opening cover 20 is configured to match the Rosemount transmitter cover and tightly cover it. The rotating handle 10 can be a long strip structure to facilitate the operation of rotating the cover. The inner wall of the cover opening cover 20 is provided with at least one radial protrusion 21 along its depth direction. The radial protrusion 21 matches the inner recess of the Rosemount transmitter cover. Matching here can mean that the radial protrusion 21 and the inner recess can be embedded and have the same or substantially the same cross-sectional shape, ensuring a tight connection between the tool and the cover during the cover opening process.

[0031] In some preferred embodiments, to enhance the stability of the cover opening process, at least one position-limiting latch 22 is further provided on the inner wall of the cover opening body 20. This position-limiting latch 22 is designed to engage within the slot in the Rosemount transmitter cover, effectively preventing relative sliding between the tool and the cover during the cover opening process. In other words, under the combined action of the radial protrusion 21 and the position-limiting latch 22, after the cover opening body 20 covers the Rosemount transmitter, the radial protrusion 21 engages within the inner recess, and the position-limiting latch engages within the slot, ensuring the stability and reliability of the cover opening process.

[0032] Furthermore, the position-limiting engaging member 22 is cleverly arranged at the bottom of the radial protrusion 21 and has a certain radial protrusion relative to the radial protrusion 21. This design not only ensures a tight fit between the position-limiting engaging member 22 and the slot, but also further improves the smoothness and reliability of the cover opening process.

[0033] To optimize the tool's force distribution and reduce the risk of damage to the watch cover, the radial protrusions 21 and the position-limiting engaging members 22 are symmetrically arranged along the center of the cover opening housing 20. This design ensures that the tool applies a more uniform force to the watch cover during the opening process, effectively avoiding damage caused by excessive local force.

[0034] Specifically, the six recessed sections of the Rosemount transmitter cover and the six radial protrusions 21 ensure a tight fit between the tool and the cover, making the cover opening process smoother and more manageable. This design not only improves the tool's ease of use but also further enhances its stability and reliability.

[0035] To enhance the tool's practicality and portability, a connecting rod 30 is installed between the rotating handle 10 and the lid opening cover 20. Furthermore, the connecting rod 30 is detachably connected to both the lid opening cover 20 and the rotating handle 10. This design makes the tool more flexible and convenient to carry and store, meeting the needs of various usage scenarios.

[0036] In addition, anti-slip grooves or anti-slip protrusions are added to the axial outer wall of the rotating handle 10. This humanized design effectively enhances the stability and comfort of the operator when holding and rotating the tool, further improving the user experience of the tool.

[0037] Finally, to ensure the tool can penetrate deeply and stably into the inner recess of the watch cover, the length of the radial protrusion 21 is specially designed. Its length is at least 1 / 2 of the depth of the inner recess of the watch cover. This design ensures a tight fit between the tool and the watch cover, thereby improving the efficiency and success rate of opening the watch cover.

[0038] The highly efficient and stable Rosemount transmitter cover removal tool provided by this utility model has demonstrated significant advantages and effectiveness in practical applications. It not only addresses the inconvenience and poor stability of traditional cover removal tools, but also improves work efficiency and user experience through structural optimization and user-friendly design. Therefore, this utility model has broad practical value and market prospects.

[0039] The present invention is merely a preferred embodiment and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
