Description

Technical Field

[0001] The utility model relates to the technical field of thermal resistors, in particular to an anti-corrosion and wear-resistant thermal resistor. Background Art

[0002] Thermal resistors are the most commonly used temperature detectors in the medium and low temperature zones. Thermal resistor temperature measurement is based on the property that the resistance value of a metal conductor increases with the increase of temperature to measure temperature. Its main features are high measurement accuracy and stable performance. Among them, platinum thermal resistors have the highest measurement accuracy. They are not only widely used in industrial temperature measurement, but also made into standard reference instruments. Thermal resistors are mostly made of pure metal materials, with platinum and copper being the most commonly used. In addition, materials such as nickel, manganese and rhodium have begun to be used to manufacture thermal resistors. There are many types of temperature sensing materials commonly used in metal thermal resistors, with platinum wire being the most commonly used. In addition to platinum wire, metal thermal resistor materials for industrial measurement include copper, nickel, iron, iron-nickel, etc. The temperature measurement principle of thermal resistors is to measure temperature and temperature-related parameters based on the property that the resistance value of a conductor or semiconductor changes with temperature. Thermal resistors are mostly made of pure metal materials, with platinum and copper being the most commonly used. Materials such as nickel, manganese and rhodium have begun to be used to manufacture thermal resistors. Thermal resistors usually need to transmit resistance signals through leads to computer control devices or other secondary instruments.

[0003] The Chinese invention patent with application number CN219551714U discloses a corrosion-resistant and wear-resistant thermal resistor, which includes a resistor body and a protective sleeve, wherein a resistor head is fixedly connected to the top of the resistor body, and two groups of mutually symmetrical grooves 1 and 2 are respectively opened on the inner wall of the protective sleeve, wherein a fixing block is fixedly connected inside the groove 1, and a clamp is movably connected inside the groove 2, and an anti-corrosion layer is provided on the outer wall of the protective sleeve. The utility model sleeves the protective sleeve on the outer wall of the resistor body, inserts the resistor body into the protective sleeve, so that the resistor body contacts the clamp and one side of the fixing block, and the arc-shaped opening on one side of the fixing block is close to the outer wall of the resistor body. The bottom end of the clamp is affected by the elasticity of the telescopic spring, and a clamping effect is formed on the bottom end of the resistor body, so that the resistor body inserted into the protective sleeve is fixed by the fixing block and the clamp, and the resistor body inside the protective sleeve is reduced and reduced to be damaged by shaking, and the protection of the device is further improved.

[0004] However, in the measurement process of the conventional thermistor, the thermistor is manually stirred inside the solvent by hand, and the temperature is measured through the resistance change of the thermistor at the end. Since the thermistor is directly exposed to the measurement environment, it is inevitable that the thermistor collides with the machine, which leads to the occurrence of undesirable phenomena such as damage to the thermistor.

[0005] Although Chinese patent CN219551714U realizes effective protection of the thermal resistor, too many protective covers prevent direct contact between the fluid and the thermal resistor, which greatly reduces the accuracy of temperature detection. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes an anti-corrosion wear-resistant thermal resistor.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An anti-corrosion wear-resistant thermal resistor, comprising a handle, and also comprising:

[0009] An indirect temperature measurement component includes a thermal resistor, which is plugged and installed inside the sleeve. A marble is arranged at the bottom of the sleeve. A water inlet groove is opened on the upper side of the sleeve. A conduit is butt-mounted on one side of the water inlet groove. A water pump is butt-mounted on one side of the conduit. An overflow box is butt-mounted on the bottom of the sleeve. An overflow groove is arranged inside the overflow box, and overflow holes are arranged around the overflow groove.

[0010] Further technical solutions include:

[0011] The wiring assembly comprises a wire butt-jointedly installed on one side of the thermal resistor, a terminal is butt-jointedly installed on one side of the wire, and a socket is arranged inside the terminal.

[0012] According to a further technical solution, a cotton pad is filled and installed between the top of the thermal resistor and the sleeve.

[0013] According to a further technical solution, a wire box is installed on the outer side of the wire.

[0015] Compared with the prior art, the utility model provides an anti-corrosion wear-resistant thermal resistor, which has the following beneficial effects:

[0016] Through the indirect temperature measurement components and the separately set wiring components, the thermal resistor of this product is placed inside the casing. We introduce the external solvent into the casing through a water pump and a catheter, and use the contact between the thermal resistor and the solvent inside the casing to achieve temperature measurement. The problem of directly stirring the thermal resistor in the solvent by hand and thus damaging the thermal resistor is avoided. At the same time, in order to ensure the accuracy of the measurement, we need to constantly update the solvent inside the casing; therefore, we set up an overflow tank and overflow box that can reflux at the bottom of the device, so that the solvent inside the device is always circulated with the outside world, thereby ensuring that the thermal resistor inside the device is always in a protected state.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1: Reference Figure 1 - Figure 4 , an anti-corrosion wear-resistant thermal resistor, comprising a handle 1, and further comprising:

[0025] The indirect temperature measurement component 2 indirectly isolates the thermal resistor 4 from the machine by pumping water through the sleeve 5, thereby avoiding collision damage caused by direct contact between the thermal resistor 4 and the machine. The indirect temperature measurement component 2 includes a thermal resistor 4, which is a component for temperature measurement. The thermal resistor 4 is plugged and installed inside the sleeve 5, and a marble 6 is arranged at the bottom of the sleeve 5, and the function of the marble 6 is to buffer. A water inlet groove 10 is provided on the upper side of the sleeve 5, and a water pump 12 draws electrolyte into the interior of the device through a conduit 11 and the water inlet groove 10. A conduit 11 is docked and installed on one side of the water inlet groove 10, and a water pump 12 is docked and installed on one side of the conduit 11. An overflow box 7 is docked and installed at the bottom of the sleeve 5, and the overflow hole 9 on the overflow box 7 can realize the discharge of electrolyte in real time, thereby making the temperature measurement more accurate. An overflow groove 8 is arranged inside the overflow box 7, and overflow holes 9 are arranged around the overflow groove 8.

[0026] An anti-corrosion wear-resistant thermal resistor, further comprising:

[0027] The wiring assembly 3 includes a wire 14 that is butt-connected to one side of the thermal resistor 4, and the wire 14 is connected to an external power source through a socket 17 on a terminal 15. A terminal 15 is butt-connected to one side of the wire 14, and a socket 17 is provided inside the terminal 15.

[0028] A corrosion-resistant and wear-resistant thermal resistor is disclosed. A cotton pad 13 is filled and installed between the top of the thermal resistor 4 and the sleeve 5. The cotton pad 13 functions to protect the top of the thermal resistor 4.

[0029] A corrosion-resistant and wear-resistant thermal resistor, wherein a wire box 16 is sleeved and installed on the outer side of a wire 14, and the wire box 16 is a location for installing a cable.

[0030] A corrosion-resistant and wear-resistant thermal resistor. A handle 1 is butt-jointedly mounted on one side of a sleeve 5. The handle 1 is a component for holding the device.

[0031] In the actual use of this device, in order to avoid the technical problem of directly stirring the thermistor in the electrolyte to be measured in the prior art, thereby causing damage to the thermistor, an indirect temperature measurement component 2 is specifically proposed; the thermistor 4 of this device is directly plugged and installed inside the sleeve 5, wherein the water pump 12 draws the external electrolyte into the sleeve 5 through the conduit 11; the thermistor 4 achieves the effect of temperature measurement in the process of contacting with the electrolyte; since the electrolyte is drawn into the sleeve 5 and contacts the thermistor 4, damage caused by direct contact between the thermistor 4 and the machine is avoided. In addition, in order to increase the measurement accuracy, it is necessary to continuously update the electrolyte inside the sleeve 5, so we installed an overflow box 7 at the bottom of the sleeve 5, and exchanged electrolytes with the outside world in real time through the overflow tank 8, so that the thermistor 4 detects uniform electrolytes, and the temperature measurement effect of the electrolyte is more stable.
