Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensors, and in particular relates to a temperature sensor with a mounting structure. Background Art

[0002] The PT100 temperature sensor is a platinum resistance thermometer whose resistance changes with temperature. The 100 after PT indicates a resistance of 100 ohms at 0°C and approximately 138.5 ohms at 100°C. It is also used in generator sets. Conventional PT100s are installed inside the generator set, making them difficult to maintain if damaged. Therefore, the practice of installing PT100s at the ends of the generator windings has evolved. Installing the temperature sensor at the ends allows for easy maintenance and replacement.

[0003] During installation, existing temperature sensors mainly rely on their own threads for fixation. This connection method is relatively simple. Once the threaded connection part is damaged, there is no other structure to assist in installation. In addition, there are also problems in the installation stability, so there is room for improvement. Utility Model Content

[0004] The purpose of the present utility model is to provide a temperature sensor with a mounting structure to solve the problem of inadequacies in the mounting method of the existing temperature sensor mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temperature sensor with a mounting structure, comprising a probe rod; a threaded barrel, which is concentrically arranged with the probe rod and is located outside the probe rod, and the threaded barrel is fixed to the edge of the end of the probe rod to ensure that the bottom end of the probe rod is reserved with an area for connection with the transmission harness, thereby realizing the transmission of subsequent signals. During installation, the threaded barrel is penetrated by the wind turbine generator set and fixed by threads; it also includes a mounting assembly, which consists of a connecting piece and a mounting piece, wherein the connecting piece is sleeved on the outside of the threaded barrel, and the two are fixed by spot welding; there are two mounting pieces, which are rotatably arranged at the two end positions of the connecting piece respectively, and a bolt is penetrated on the mounting piece, which is fixed to the wind turbine generator set to realize installation, and cooperate with the threaded barrel to realize double fixation.

[0006] Preferably, the connecting member includes a ring, which is sleeved on the outside of the threaded barrel, and an integrated fitting plate is provided on both sides of the ring. The surface of the fitting plate facing the probe rod is evenly distributed with abutments, which can increase the friction force when connected to the wind turbine by increasing the abutments. The mounting member is rotatably set at the end position of the fitting plate so that its own angle can be adjusted according to the position of the mounting surface.

[0007] Preferably, the mounting part is a mounting plate, and an axis or hinge is connected between the mounting plate and the bonding plate. The mounting plate rotates around the axis of the axis or hinge to achieve installation in different positions. A strip hole is opened on the mounting plate, and bolts are passed through the strip hole to install the wind turbine.

[0008] Preferably, an integrated nut is fixed to the bottom end of the threaded barrel, and the collar is fixed to the nut by spot welding, thereby fixing the position of the installation component.

[0009] Preferably, a connecting cylinder is further installed at the bottom end of the nut, a transmission wire harness is inserted into the interior of the connecting cylinder, and the transmission wire harness is connected to the bottom end of the probe rod.

[0010] Preferably, a protective piece is provided on the transmission harness, and the protective piece abuts against the inner wall of the connecting tube, thereby separating the transmission harness and the connecting tube to avoid damage caused by the abutment between the two.

[0011] Preferably, the protective part includes a rubber ring that is sleeved on the transmission harness, and an integrated tightening portion is formed at one end of the rubber ring, which abuts against the inner wall of the connecting tube to achieve a secure installation of the two. Horizontally extending protrusions are formed on both sides of the other end of the rubber ring, and the rubber ring and the tightening portion can be easily pulled out and separated from the connecting tube through the protrusions.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed installation component can cooperate with the threaded barrel to achieve double installation and fixation, ensuring the installation strength of the temperature sensor. When the thread on the threaded barrel is stripped or damaged, it can also be installed instead. It can also be adjusted according to the installation angle of the installation surface. The overall flexibility is high, which improves the shortcomings of the existing structure in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The steps to move the temperature sensor from inside the generator set to the end location are as follows:

[0037] Move the cooler: Remove the cooler-related wiring in the auxiliary outlet box, remove the air ducts on both sides of the cooler, and remove the cooler mounting bolts; use a manual hoist, round steel, and crowbar to move the cooler toward the right front end of the motor and secure it;

[0038] Component inspection and selection: Before binding, use a multimeter with the ohm range to measure the resistance of the temperature sensor to ensure that the difference between the maximum and minimum resistance values ​​of the temperature sensors installed on the same generator is within 1Ω. Select 6 components within the normal range as the temperature measurement components to be installed.

[0039] Positioning components: Select the coil directly above the winding end as the first coil and set it as the W phase. For 2.0MW motors, select the second coil from the left as the V phase, and the seventh coil from the right as the U phase. For 1.5MW motors, select the second coil from the left as the V phase, and the fifth coil from the right as the U phase. The three positions above should avoid the bracket. If avoiding the bracket is not possible, the entire unit should be offset to the right or left by the same amount, ensuring sufficient space for operation.

[0040] Component Binding: Note! During operation, secure all tools with the supplied polyester tubing, leaving the end of the tubing outside the machine base to prevent the tools from falling into the base. Bind the temperature sensor for the same phase to both sides of the beveled edge of the coil, as close to the notch as possible. Wrap it with three layers of glass ribbon and tie a knot. The component outlets should be marked with UVW; the glass ribbon should completely and tightly wrap the temperature measuring component; the component signal line should be covered with a φ4 silicon glass paint tube, and glass silk should be used to tie (knot) every 5 coils on the outside of the large end hoop near the end of the coil, and lead it along the outer large end hoop to the direction of the wire hole of the auxiliary outlet box (pay attention to the appropriate tightness of the binding, the deflection of the suspended part should be 1 finger, to avoid the temperature sensor signal line being torn due to too tight binding); the original temperature measurement wire harness is tied behind the terminal block with a small cable tie; the newly installed components are gathered into a bundle, and fixed with alkali-free glass ribbon or cable tie at the leech nail position of the round hole on the upper part of the machine base, and introduced into the auxiliary outlet box; the resistance of each component is measured again in the auxiliary outlet box. After confirming that it is intact, brush JZ-11 glue on the binding and knotting parts of the glass ribbon and each hollow polyester sleeve. When brushing glue, ensure that the entire binding area is completely covered with glue, and the glue should be evenly applied; restore the cooler according to the cooler relocation method; restore the cooler wiring according to the auxiliary outlet box wiring label, and connect the newly added winding temperature measurement to the terminal block with the corresponding serial number; after completion, take photos of the binding component position, the leech nail position entering the round hole, and the terminal block position for reference.
