[0002] In the fields of petrochemical industry, industrial automation, etc., digital integrated temperature transmitters are widely used as key temperature monitoring instruments. Such transmitters usually include a temperature probe at the lower end. During production and use, the temperature probe will be immersed in the liquid medium to be tested. Due to its precise characteristics, this component is crucial to the overall performance and reliability of the instrument. When testing and processing liquid media, an integrated damage-proof and leak-proof temperature transmitter is required.

[0003] At present, in the production process of manufacturers, due to the limitations of the casting process, defects such as sand holes and welds sometimes appear on the surface of the temperature probe at the lower end of the temperature transmitter. These tiny pores not only affect the mechanical strength of the temperature probe, but may also cause oil to penetrate into the probe during the production and use of the instrument, causing failures. In addition, during the loading and unloading, transportation or actual production and use of the instrument, the temperature probe is susceptible to unexpected external force impact or extrusion, causing the probe to deform or be damaged, seriously affecting its measurement accuracy and service life, which not only increases maintenance costs, but is also likely to cause temperature monitoring inaccuracy or even failure, posing a potential threat to production safety.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 - Figure 6 As shown, this embodiment provides an integrated damage-proof and leak-proof temperature transmitter, including a transmitter body 1, and also including:

[0028] The temperature measuring probe 6 is arranged inside the transmitter body 1;

[0029] A fixed plate 2, fixedly connected to the outside of the transmitter body 1;

[0030] The protection component is sleeved on the outside of the temperature measuring probe 6 and is used to protect the temperature measuring probe 6, thereby effectively extending the service life of the temperature measuring probe 6;

[0031] The mounting assembly is arranged inside the fixing plate 2 and is used to fix the protection assembly to the transmitter body 1, so that the protection assembly can effectively protect the temperature measuring probe 6;

[0032] The sealing component is arranged inside the protective component and is used to improve the sealing between the protective component and the transmitter body 1, thereby effectively improving the sealing between the protective component and the temperature measuring probe 6.

[0033] The above working principle: when the temperature measuring probe 6 needs to be protected, it is only necessary to first fix the protection component on the outside of the fixed plate 2 through the installation component. At this time, the protection component can be sleeved on the outside of the temperature measuring probe 6, so that the temperature measuring probe 6 can be effectively protected by the protection component to prevent the temperature measuring probe 6 from being impacted and squeezed by the outside, resulting in deformation and damage of the temperature measuring probe 6, and effectively extending the service life of the temperature measuring probe 6. At the same time, through the cooperation between the sealing component and the protection component, the sealing between the protection component and the transmitter body 1 can be effectively improved, thereby effectively improving the sealing between the protection component and the temperature measuring probe 6, ensuring that even if there are sand holes in the casting of the temperature measuring probe 6, the oil can be prevented from penetrating into the inside of the temperature measuring probe 6 through the sand holes, thereby eliminating the hidden dangers of oil leakage caused by sand holes, saving time and effort.

[0034] In order to effectively protect the temperature measuring probe 6, the protection component includes a protective shell 5 which is sleeved on the outside of the temperature measuring probe 6. The upper surface of the protective shell 5 is fixedly connected to a connecting disk 3. The upper surface of the connecting disk 3 is provided with a guide groove for the movement of the fixed disk 2. The material of the protective shell 5 is aluminum alloy. When it is necessary to protect the temperature measuring probe 6, it is only necessary to first fix the connecting disk 3 and the fixed disk 2 through the installation component. At this time, the protective shell 5 can be sleeved on the outside of the temperature measuring probe 6, so that the temperature measuring probe 6 can be effectively protected by the protective shell 5. Since the aluminum alloy material has the advantages of good corrosion resistance and high strength, the protective shell 5 also has the above advantages, which can further enhance the protective effect of the protective shell 5 on the temperature measuring probe 6 and effectively extend the service life of the protective shell 5.

[0035] Considering that when the temperature measuring probe 6 is protected, it is necessary to first fix and install the connecting disk 3 and the fixed disk 2, so that the protective shell 5 can be effectively sleeved on the outside of the temperature measuring probe 6 to protect the temperature measuring probe 6, so the installation component includes a plurality of telescopic rods 7 fixedly connected to the inside of the fixed disk 2, and the telescopic ends of the plurality of telescopic rods 7 are fixedly connected to the plug rods 8, and the outsides of the plurality of telescopic rods 7 are sleeved with reset springs 9, and the plurality of reset springs 9 are in contact between the plug rods 8 and the fixed disk 2. The outsides of the fixed disk 2 and the connecting disk 3 are provided with guide grooves for the plug rods 8 to move. When it is necessary to fix and install the connecting disk 3 and the fixed disk 2, it is only necessary to press the plug rods 8 first. At this time, the plug rods 8 The reset spring 9 and the telescopic rod 7 will be squeezed simultaneously, and then the connecting disk 3 is sleeved on the outside of the fixed disk 2, and then the plug-in rod 8 is loosened. At this time, the reset spring 9 is reset, driving the plug-in rod 8 to reset and move synchronously. When the plug-in rod 8 is plugged into the guide groove outside the connecting disk 3, the connecting disk 3 and the fixed disk 2 can be fixed. At this time, the protective shell 5 can be sleeved on the outside of the temperature measuring probe 6, so that the protective shell 5 can effectively protect the temperature measuring probe 6. At the same time, the protective shell 5 can be conveniently installed without using welding and bolts, which effectively improves the installation efficiency of the protective shell 5, reduces the workload of the staff, and facilitates the staff to check and replace the instrument.

[0036] In order to further improve the sealing between the connecting disk 3 and the fixed disk 2, and thus further improve the sealing between the protective shell 5 and the temperature probe 6, the sealing assembly includes a sealing gasket bonded to the inner wall and the inner bottom of the connecting disk 3. After the installation between the connecting disk 3 and the fixed disk 2 is completed, the sealing gasket can effectively improve the sealing between the connecting disk 3 and the fixed disk 2, thereby effectively improving the sealing between the protective shell 5 and the transmitter body 1, and further effectively improving the sealing between the protective shell 5 and the temperature probe 6, ensuring that even if there are sand holes in the casting of the temperature probe 6, oil can be prevented from penetrating into the interior of the temperature probe 6 through the sand holes, thereby eliminating the hidden danger of oil leakage caused by sand holes.

[0037] In order to conveniently install the transmitter body 1 to the required position, so that the transmitter body 1 can be effectively used, the outside of the protective shell 5 is fixedly connected with a mounting disk 4, and the upper surface of the mounting disk 4 is provided with threaded holes for the movement of fixing bolts at equal intervals. When the transmitter body 1 needs to be installed, the mounting disk 4 only needs to be fixed to the required position by the fixing bolt. At this time, the transmitter body 1 can be fixedly installed, so that the transmitter body 1 is convenient to use.

[0038] In addition, in order to further enhance the protective effect of the protective shell 5 on the temperature measuring probe 6, an elastic buffer sleeve 10 is bonded to the inner wall of the protective shell 5. Through the provision of the elastic buffer sleeve 10, the protective shell 5 can be effectively cooperated to perform buffering and protection against the impact force in the external environment, thereby further enhancing the protective effect of the protective shell 5 on the temperature measuring probe 6, and further effectively extending the service life of the temperature measuring probe 6.
