Description

Technical Field

[0001] The utility model relates to a transmitter, in particular to a high-precision temperature transmitter, belonging to the technical field of temperature transmitters. Background Art

[0002] A temperature transmitter is a device that converts temperature signals into standard current or voltage signals. It is usually used in conjunction with a temperature sensor to measure and monitor temperature changes in various industrial processes. The working principle of a temperature transmitter is based on thermistor effect or thermoelectric effect.

[0003] After searching, a Chinese patent with announcement number CN220853899U discloses a high-precision PA bus temperature transmitter, including a temperature sensor, the bottom of which is fixedly connected to a connecting shaft. The above-mentioned free adjustment structure is adopted to achieve that when the temperature transmitter is installed on a higher pipeline, the temperature sensor can be first fixedly installed in a position convenient for checking the situation. At this time, the temperature sensing element is stretched to the pipeline where it needs to be installed for fixed installation, and then the slide bar is pressed into the first slide groove for locking and fixing, so as to prevent the shaft from being rotated by external force and causing expansion and contraction of the wire, thereby causing damage to the wire, and effectively achieving the free adjustment of the height, so as to achieve the purpose of adjusting the height of the temperature sensor without changing the height of the temperature sensing element.

[0004] Although the above scheme can achieve the purpose of adjusting the height of the temperature detector without changing the height of the temperature sensing component, it is difficult to conveniently disassemble and assemble the wire body of the temperature transmitter in the above patent. In order to facilitate the transportation of the entire device, a disassembly and assembly method is generally adopted; for this reason, we provide a high-precision temperature transmitter to solve the above problems.

The close cooperation between the reciprocating screw 16 and the linkage position control frame 17 can effectively realize the effect of the linkage position control frame 17 moving back and forth.

[0027] See also Figure 1 and Figure 3A linkage support rod 19 is fixedly arranged at the bottom of the linkage control position frame 17, and the bottom of the linkage support rod 19 is rotatably connected to the top of the second smooth roller 20. The second smooth roller 20 slides inside the guide track 21, and the guide track 21 is fixedly arranged between the two groups of support frame bodies 1. The cooperation between the linkage support rod 19, the second smooth roller 20 and the guide track 21 can effectively ensure that the second smooth roller 20 slides and rotates in the guide track 21, thereby ensuring the stability of the movement process of the linkage control position frame 17.

[0028] See also Figure 1 and Figure 3 A conductor position control clamp 18 is fixedly arranged on the top of the linkage position control frame 17, and a conductor body 11 is arranged between the conductor position control clamps 18. The arrangement of the conductor position control clamps 18 can effectively control the conductor body 11, thereby ensuring the subsequent orderly wire collection operation.

[0029] See also Figure 1 There are two groups of support frame bodies 1, and a winding rod body 9 is placed between the two groups of support frame bodies 1. The outer circumferential surface of the winding rod body 9 is fixedly connected to one end of the wire body 11. The setting of the winding rod body 9 can effectively pull the wire body 11 when the winding rod body 9 is rotated by external force, so that the wire body 11 is wound around the winding rod body 9.

[0030] See also Figure 1 A temperature transmitter 12 is fixedly provided at the other end of the wire body 11. The temperature transmitter 12 is a prior art and will not be described in detail. The setting of the temperature transmitter 12 can convert the temperature signal into a standard current or voltage signal output. A shunt chamber 13 is fixedly provided on one side of the temperature transmitter 12. The shunt chamber 13 is fixedly connected with an auxiliary wire 14. There are three groups of auxiliary wires 14. One end of the three groups of auxiliary wires 14 is respectively fixedly provided with a temperature sensor 15. The temperature sensor 15 is a prior art and will not be described in detail. Under the action of the auxiliary wires 14 and the shunt chamber 13, the three groups of temperature sensors 15 can synchronously monitor the temperature of the surrounding environment, thereby ensuring the accuracy of the data.

[0031] See also Figure 1 and Figure 4 A wire limiting disk 10 is fixedly arranged on the outer circumferential surface of the winding rod main body 9, and a positioning linkage plate 2 is rotatably arranged on the top of the support frame main body 1. There are two groups of positioning linkage plates 2, and the two groups of positioning linkage plates 2 are rotatably arranged on the tops of the two groups of support frame main bodies 1. The purpose of setting multiple groups of positioning linkage plates 2 is to preliminarily limit the two ends of the winding rod main body 9, so as to ensure that the winding rod main body 9 will not fall off during the rotation process.

[0032] See also Figure 1 and Figure 2 The bottom of the two groups of positioning linkage plates 2 are respectively fixed with control limiting plates 3, and there are two groups of control limiting plates 3. The setting of the control limiting plates 3 can effectively facilitate the restriction of the positioning linkage plates 2 by subsequent components, thereby ensuring the stability of the positioning linkage plates 2 when they are in a stationary state. The middle part of the positioning linkage plate 2 is rotatably provided with a first smooth roller 7, and the interior of the positioning linkage plate 2 is fixedly provided with a positioning limiting column 8. The setting of the first smooth roller 7 and the positioning limiting column 8 can effectively enhance the stability of the rotation process of the winding rod main body 9, and at the same time ensure that the winding rod main body 9 can rotate more smoothly.

[0033] See also Figure 2 A control and limiting plate 3 is fixedly arranged at the bottom of the positioning linkage plate 2, and a reinforced support plate 4 is fixedly arranged on one side of the control and limiting plate 3. The middle part of the reinforced support plate 4 is rotatably connected to the outer circumferential surface of the one-way screw rod 5, and an external driving plate 6 is fixedly arranged at one end of the one-way screw rod 5. The one-way screw rod 5 and the external driving plate 6 are arranged so that the one-way screw rod 5 gradually moves through the rotation of the external driving plate 6, and finally limits the control and limiting plate 3, thereby ensuring the stability of the positioning linkage plate 2.

[0034] Working principle: The reeling rod body 9 is rotated in the support frame body 1 by external force, and the reciprocating screw rod 16 is also rotated. At this time, the rotation of the reeling rod body 9 will pull the wire body 11, so that the wire body 11 is gradually shortened and wound around the reeling rod body 9. In the process of reeling, due to the rotation of the reciprocating screw rod 16, the linkage position control frame 17 will move back and forth under the action of the reciprocating screw rod 16, so that the linkage support rod 19 drives the second smooth roller 20 to move in the guide track 21. At the same time, under the action of the wire position control clamp 18, The position of the conductor body 11 is changed to ensure that the conductor body 11 is wound around the winding rod body 9 in an orderly manner, and at the same time, the shunt chamber 13 on the temperature transmitter 12 and the temperature sensor 15 on the attached conductor 14 are synchronously recovered, and the external driving disk 6 is rotated by external force to rotate the one-way screw rod 5 and move horizontally, and the linkage plate 2 is positioned by the external force plate again to release the restriction on the winding rod body 9, and the winding rod body 9 can be directly taken out of the support frame body 1, thereby effectively realizing the effect of convenient disassembly and assembly of the conductor body 11.
