Description

Technical Field

[0001] The utility model relates to the technical field of instrument inspection, and in particular to an auxiliary protection device based on instrument inspection. Background Art

[0002] Instruments are a general term for instruments that measure temperature, air pressure, electricity, blood pressure, flow, and other functions. They resemble timepieces and display numerical values directly on a scale. They are primarily categorized as pressure instruments, temperature instruments, flow meters, electrical instruments, electronic measuring instruments, optical instruments, analytical instruments, and laboratory instruments.

[0003] Instrument reliability is another important performance metric sought by instrument engineers in chemical companies. Reliability and instrument maintenance requirements are mutually exclusive: high instrument reliability indicates low maintenance requirements, while low instrument reliability indicates high maintenance requirements. Most chemical company testing and process control instruments are installed on process pipelines, towers, kettles, tanks, and vessels. Furthermore, the continuity of chemical production is crucial for both production safety and the personal safety of instrument maintenance personnel. Therefore, chemical companies require the lowest possible maintenance requirements for their testing and process control instruments, which in turn requires the highest possible reliability.

[0004] It is widely used in industry, agriculture, transportation, science and technology, environmental protection, national defense, culture, education, health, people's life and other aspects.

[0005] However, during the instrument inspection process, especially the water pressure, flow and water temperature instruments, they need to be connected to the pipeline for testing. During the test, the instrument connection diameters are similar, and different diameter connection ports are required to connect the instruments. In view of this, an auxiliary protection device based on instrument inspection is developed. Utility Model Content

[0026] The following will be combined with 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.

[0027] like Figures 1 to 3 As shown, this embodiment proposes an auxiliary protection device based on instrument inspection, including

[0029] The flow observation component 3 is arranged in the detection tube 2;

[0030] Detection installation component 4, the detection installation component 4 is arranged on the detection plate 1;

[0031] The flow observation assembly includes a triangular frame 3-1, which is arranged inside the detection tube 2. A plug-in sleeve 3-2 is arranged at the center of the triangular frame 3-1, and a rotating shaft 3-3 is arranged inside the plug-in sleeve 3-2. A follower disk 3-4 is arranged at one end of the rotating shaft 3-3, a driving block 3-5 is arranged on the end face of the rotating shaft 3-3, a paddle frame 3-6 is arranged on the side surface of the driving block 3-5, and a prompt frame 3-7 is arranged at the end of the paddle frame 3-6.

[0032] In this embodiment, the triangular frame 3-1 is placed in the detection tube 2, and the plug-in sleeve 3-2 provides a rotation effect for the rotation shaft 3-3. When water flows in the detection tube 2, the water flow impacts the paddle frame 3-6, causing the paddle frame 3-6 to drive the driving block 3-5 to rotate. As the driving block 3-5 drives the rotation shaft 3-3 to rotate, the prompt frame 3-7 rotates with the paddle frame 3-6.

[0033] Specifically, a transparent ring 3-8 is provided on the detection tube 2, and the prompt frame 3-7 is embedded in the transparent ring 3-8.

[0034] In this embodiment, during the rotation of the paddle frame 3-6, the user can check the rotation frequency of the prompt frame 3-7 at the transparent ring 3-8, and thus judge the water flow speed according to the rotation speed of the prompt frame 3-7.

[0035] Furthermore, the detection installation assembly 4 includes a detection instrument installation port 4-1, which is arranged on the upper end surface of the detection tube 2. A sealing cover 4-2 is provided on the detection instrument installation port 4-1, and a lifting line 4-3 is provided on the sealing cover 4-2. The lifting line 4-3 is fixedly connected to the detection disk 1.

[0036] In this embodiment, the sealing cover 4-2 on the detection instrument installation port 4-1 has a sealing effect, and the hanging line 4-3 is connected to the sealing cover 4-2, so that the sealing cover 4-2 will not be lost due to frequent unscrewing.

[0037] Furthermore, a support frame 5 is provided on the upper end surface of the detection disk 1, a semicircular cover 6 is clamped on the detection tube 2, a limiting strip 7 is provided on the support frame 5, a limiting groove 8 is provided at the bottom of the semicircular cover 6, and the limiting strip 7 is embedded in the limiting groove 8.

[0038] In this embodiment, the semicircular cover 6 is buckled onto the detection tube 2 , and the limiting strip 7 is embedded in the limiting groove 8 , so that the supporting frame 5 fixes the semicircular cover 6 .

[0039] Furthermore, an outer surface of one side of the detection tube 2 is provided with an external thread 9 and an inner wall is provided with an internal thread 10 , and a pressurized drain pipe 11 is provided on the other side of the detection tube 2 .

[0040] In this embodiment, the external thread 9 is used to connect a pipe with a larger diameter than the detection tube 2, the internal thread 10 is used to connect a pipe with a smaller diameter than the detection tube 2, and the pressurized drainage pipe 11 can divert the water flow in the detection tube 2.

[0041] Furthermore, there are several detection instrument installation ports 4-1, and the diameters of the multiple detection instrument installation ports 4-1 are different. The outer surface of the detection instrument installation port 4-1 is provided with a connecting thread 12, and the connecting thread 12 is screwed and connected to the sealing cover 4-2.

[0042] In this embodiment, the connecting thread 12 is used for screwing and sealing the sealing cover 4 - 2 .

[0043] When instrument detection is required, after screwing the instrument onto the detection instrument installation port 4-1 of matching diameter, the external thread 9 is used to connect the pipe with a larger diameter than the detection tube 2, and the internal thread 10 is used to connect the pipe with a smaller diameter than the detection tube 2. The pressurized discharge pipe 11 can divert the water flow in the detection tube 2. After the water flow circulates, the triangular frame 3-1 is placed in the detection tube 2, and the plug-in sleeve 3-2 provides the rotation effect of the rotating shaft 3-3. When water flows in the detection tube 2, the water flow impacts the pulp frame 3-6, causing the pulp frame 3-6 to drive the driving block 3-5 to rotate. As the driving block 3-5 drives the rotating shaft 3-3 to rotate, the prompt frame 3-7 rotates with the pulp frame 3-6. During the rotation of the pulp frame 3-6, the user can check the rotation frequency of the prompt frame 3-7 at the transparent ring 3-8, and thus judge the water flow speed according to the rotation speed of the prompt frame 3-7.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
