Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature sensor protection technology, specifically a snow melting temperature sensor with a protective structure. Background Technology
[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are classified into two categories according to the characteristics of sensor materials and electronic components: resistance temperature detectors (RTDs) and thermocouples. During heavy snowfall in winter, a lot of snow accumulates on the roofs of some houses or on the surface of photovoltaic panels, which puts a large load on the roofs, especially metal roofs or the surface of photovoltaic panels, and poses a significant safety hazard. It is necessary to install snow melting equipment to melt the snow by heating the surface of the roof or photovoltaic panels. Therefore, temperature sensors for snow melting are required.
[0003] Since the temperature sensor used for snow melting is installed outdoors and only needs to be used in winter, it remains outdoors during other seasons. This makes the sensor probe surface prone to dust accumulation or corrosion, ultimately affecting its detection accuracy. Therefore, we propose a snow melting temperature sensor with a protective structure. Utility Model Content
[0004] The purpose of this invention is to provide a snow melting temperature sensor with a protective structure. By surrounding and protecting the probe inside the protective cover, the surface temperature of the metal roof or photovoltaic panel at the installation location can be transferred to the probe surface through the copper sheet and the thermally conductive copper sleeve, so that it can be detected. This can avoid dust accumulation on the probe surface during idle periods or corrosion caused by long-term exposure to the outdoors, thus making its accuracy less affected and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a snow melting temperature sensor with a protective structure, comprising a copper plate, a side plate, and a probe. The side plate is vertically fixed to the surface of the copper plate, and the probe is horizontally installed on the side of the side plate above the copper plate. A protective cover is fixed to the outer ring of the probe on the side of the side plate. A thermally conductive copper sleeve is fitted around the outer ring of the probe, and the thermally conductive copper sleeve is in thermal contact with the outer surface of the probe. A copper sheet is connected to the bottom of the thermally conductive copper sleeve, and the copper sheet passes through an opening below the protective cover to the outside, and the bottom of the copper sheet is connected to the copper plate.
[0006] By adopting the above technical solution, the copper plate is installed and fixed on the metal roof or the surface of the photovoltaic panel. Heat can be transferred to the probe position through the copper plate, copper sheet and thermally conductive copper sleeve. The temperature can be monitored when the snow melting equipment is working, and when idle, the protective cover protects the probe from dust and corrosion.
[0007] Optionally, a rubber sleeve is tightly fixed around the outer ring of the copper sheet at the through-hole position, and the outer ring of the rubber sleeve also abuts against the inner surface of the through-hole.
[0008] By adopting the above technical solution, the opening at the copper sheet penetration point can be well sealed by the rubber sleeve.
[0009] Optionally, the upper and lower outer rings of the rubber sleeve are integrally connected with extended rubber, which respectively contact the inner and outer surfaces of the protective cover.
[0010] By adopting the above technical solution, the rubber sleeve is locked inside the opening, preventing it from sliding outward.
[0011] Optionally, at least three copper sheets are fixed between the thermally conductive copper sleeve and the copper plate.
[0012] By adopting the above technical solution, more copper sheets have better heat conduction and transfer effects, reducing errors.
[0013] Optionally, thermal grease is attached and fixed to the inner surface of the thermally conductive copper sleeve, and the thermally conductive grease is in contact with the surface of the probe.
[0014] By adopting the above technical solution, the thermal grease enables the heat from the thermally conductive copper sleeve to be better transferred to the probe and thus to detect the temperature.
[0015] Optionally, the copper plate has perforations on its surface, which extend through both sides of the copper plate.
[0016] By adopting the above technical solution, the bolt passes through the copper plate through a hole, thereby securing it in place.
[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0018] 1. The technical solution of this application protects the probe by surrounding it inside the protective cover. The surface temperature of the metal roof or photovoltaic panel at the installation location can be transferred to the probe surface through the copper sheet and the thermally conductive copper sleeve, so that it can be detected. This can avoid dust accumulation on the probe surface during idle periods or corrosion caused by long-term exposure to the outdoors, thus making its accuracy less susceptible to impact.
[0019] 2. The technical solution of this application has a rubber sleeve fixed on the outer ring of the copper sheet through the through-hole. The rubber sleeve is close to the inner surface of the through-hole, which has a good sealing effect on the through-hole. Attached Figure Description

[0025] Please see Figure 1-3 This utility model provides a technical solution: a snow melting temperature sensor with a protective structure, including a copper plate 1, a side plate 2, and a probe 3. The side plate 2 is vertically fixed to the surface of the copper plate 1. To achieve the fixing method, it can be directly glued, or a hole can be drilled on the surface of the copper plate 1 and bolts can be used for installation and locking. The probe 3 is horizontally installed on the side of the side plate 2 above the copper plate 1. In order to achieve the purpose of protecting the probe 3 when it is not in use, a protective cover 4 is fixed to the outer ring of the probe 3 on the side of the side plate 2. The probe 3 is completely protected inside the protective cover 4, which will not accumulate external dust and will not be corroded when placed outdoors for a long time, thus ensuring service life and measurement accuracy.
[0026] Of course, if the above solution is adopted, the detection accuracy of probe 3 in detecting the external ambient temperature will also decrease. In order to solve this problem, a thermally conductive copper sleeve 5 is placed around the outer ring of probe 3. The thermally conductive copper sleeve 5 is in thermal contact with the outer surface of probe 3. In order to better transfer the temperature of the thermally conductive copper sleeve 5 to the outer surface of probe 3, thermally conductive silicone grease 51 is also attached and fixed to the inner surface of the thermally conductive copper sleeve 5. The thermally conductive silicone grease 51 is attached to the surface of probe 3.
[0027] The bottom of the thermally conductive copper sleeve 5 is connected to a copper sheet 52. The copper sheet 52 passes through the through hole 41 opened below the protective cover 4 to the outside, and the bottom of the copper sheet 52 is connected to the copper plate 1. The surface of the copper plate 1 is also provided with a through hole 11, which passes through both sides of the copper plate 1. In use, the copper plate 1 is in contact with the surface of a metal baffle on the roof surface with low load-bearing capacity, or in contact with the surface of a photovoltaic panel. The bolt passes through the copper plate 1 to lock the copper plate 1 to the surface of the roof metal baffle or photovoltaic panel, so that the temperature can be better transferred to the copper plate 1, transferred through the copper sheet 52 to the thermally conductive copper sleeve 5, and finally transferred to the probe 3 to be detected by the temperature.
[0028] At least three copper sheets 52 are fixed between the thermally conductive copper sleeve 5 and the copper plate 1. Since the copper plate 1, copper sheets 52 and thermally conductive copper sleeve 5 are all made of copper with excellent thermal conductivity, the temperature error detected by the probe 3 can be minimized.
[0029] Since the copper sheet 52 passes through the through-hole 41, in order to seal the through-hole 41, a rubber sleeve 6 is tightly fixed around the outer ring of the copper sheet 52 at the through-hole 41. The outer ring of the rubber sleeve 6 also abuts against the inner surface of the through-hole 41. Furthermore, the upper and lower outer rings of the rubber sleeve 6 are connected as a whole with an extension rubber 61. The extension rubber 61 respectively touches the inner and outer surfaces of the protective cover 4, thereby preventing the rubber sleeve 6 from slipping out of the through-hole 41 and falling off.
[0030] In use, the copper plate 1 is attached to the surface of the metal roof or photovoltaic panel that needs to be measured and will accumulate snow. The copper plate 1 is installed and fixed by bolts through the through hole 11. Then, the probe 3 is connected to the receiving host via wires. When there is snow on the surface of the roof or photovoltaic panel, the temperature of the roof or photovoltaic panel surface is transferred to the surface of the copper plate 1 during the snow melting process using snow melting equipment. Then, the temperature is transferred to the thermally conductive copper sleeve 5 through the thermally conductive copper sheet 52, and then to the probe 3 through the thermally conductive silicone grease 51. The temperature is detected and transmitted to the receiving host, which can determine the temperature of the roof or photovoltaic panel surface during the snow melting process. During the idle period, the probe 3 is sealed and protected inside the protective cover 4 to avoid dust accumulation and long-term exposure to the outside for corrosion.
