Description

Technical Field

[0001] This utility model belongs to the field of industrial equipment testing technology, and more specifically, it relates to a measuring device for measuring the internal temperature of equipment. Background Technology

[0002] Accurate monitoring of the internal temperature of equipment such as disinfection cabinets is crucial to ensuring the safe operation of the equipment. However, traditional temperature measurement methods and devices often have certain limitations. For example, existing internal temperature measurement of equipment mostly uses fixed temperature probes, which have the following drawbacks: 1. Current fixed-point measurements cannot reflect the internal temperature field distribution of the equipment; 2. The probe wires are prone to breakage due to long-term vibration and friction inside the equipment.

[0003] In addition, traditional temperature sensors and their connection methods face problems such as inconvenient installation and unstable fixing in actual operation. This not only increases maintenance costs but also leads to inaccurate measurement data. At the same time, the transmission wires lack effective protection measures and are easily damaged in harsh environments, affecting measurement accuracy and reliability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a measuring device for measuring the internal temperature of equipment.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A measuring device for measuring the internal temperature of equipment includes a sleeve with N through holes inside the sleeve. A transmission wire is installed in each through hole. One end of the transmission wire is provided with a temperature measuring end, and the other end is provided with a connector. The sleeve is also provided with a connector for connecting to a cabinet. N is a positive integer ≥1.

[0007] Preferably, the outer surface of the transmission wire is provided with a protective layer, which is disposed between the temperature measuring end and the sleeve.

[0008] Preferably, the protective layer is a metal corrugated pipe or a PTFE sleeve.

[0009] Preferably, one through hole is provided at the center of the sleeve, and (N-1) through holes are evenly distributed around the center of the sleeve, where N is a positive integer ≥2.

[0010] Preferably, 2≤N≤9.

[0011] Preferably, N = 1.

[0012] Preferably, the connector includes a chuck, which is installed in conjunction with a chuck A on the cabinet.

[0013] Preferably, the connector includes an external thread that mates with the internal thread on the cabinet.

[0014] Preferably, the external thread and the internal thread on the cabinet are connected by a tapered thread.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting N through holes in the sleeve to install the transmission wire, and the outer surface of each wire is provided with a protective layer (such as a metal corrugated tube or PTFE sleeve), this utility model can adapt to different measurement environments. The protective layer not only protects the wire from damage, but also, due to its bendable characteristics, allows the temperature measuring end to be placed at the specific location to be measured, while avoiding the squeezing and wear of the outer layer of the temperature probe due to the movement of certain moving devices.

[0017] 2. As in Example 2, multi-point measurement (2≤N≤9) is allowed, which increases the accuracy and comprehensiveness of temperature measurement and helps to more accurately grasp the temperature field distribution inside the disinfection cabinet, which is crucial for ensuring the safe operation of the disinfection cabinet and improving its efficiency.

[0018] 3. For application scenarios that only require single-point temperature monitoring, Example 3 provides a simplified solution (N=1), which is simple and effective and suitable for cost-sensitive or space-limited occasions;

[0019] 4. Examples 4 and 5 provide two different connection methods—chuck locking and tapered thread connection—both of which achieve quick installation and fixation. These two connection methods are easy to operate, improve assembly speed, ensure connection stability, and reduce maintenance time and cost.

[0020] In summary, this utility model allows for the setting of the length and structural design of the temperature probe insertion portion based on the position of the object being measured. It offers advantages such as flexible design, diverse measurement modes, and convenient installation. Whether it's complex multi-point measurement needs or simple single-point monitoring, it can meet the specific needs of different users. Attached Figure Description

[0029] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0030] Example 1:

[0031] like Figure 1 As shown, a measuring device for measuring the internal temperature of equipment includes a sleeve 4 with N through holes 41 inside. A transmission wire 5 is installed in each through hole 41. One end of the transmission wire 5 is provided with a temperature measuring end 1, and the other end is provided with a connector 6. The sleeve 4 also has connectors for connecting to a cabinet, where N is a positive integer ≥ 1. Specifically, the N connectors 6 are respectively connected to a receiving point on the control cabinet to receive sensor signals.

[0032] Furthermore, a protective layer 2 is provided on the outer surface of the transmission wire 5, and the protective layer 2 is disposed between the temperature measuring end 1 and the sleeve 4. The protective layer 2 is a metal corrugated tube or a PTFE sleeve, which protects the wire extending into the conductor. Since the metal corrugated tube or PTFE sleeve is flexible, it can be placed in any desired location for measurement.

[0033] Example 2:

[0034] like Figure 2 , 4 As shown in Figure 5, a measuring device for measuring the internal temperature of an equipment differs from Embodiment 1 in that a through hole 41 is provided at the center of the sleeve 4, and (N-1) through holes 41 are evenly distributed around the center of the sleeve 4, wherein 2≤N≤9 is a positive integer, that is, the temperature probe in this utility model performs multi-point measurement.

[0035] Example 3:

[0036] A measuring device for measuring the internal temperature of an equipment, differing from Embodiment 1 in that N = 1, as shown below. Figure 1 Or such as Figure 3 As shown, the temperature probe in this utility model performs single-point measurement.

[0037] Example 4:

[0038] A measuring device for measuring the internal temperature of equipment, differing from Embodiment 1 in that the connecting component includes a chuck 3, which is fitted and installed in conjunction with a chuck A8 on the cabinet 7. Specifically, as... Figure 6 As shown, chuck 3 cooperates with chuck A8 on cabinet 7, and the two chucks are locked together by clamps to achieve the purpose of quick locking.

[0039] Example 5:

[0040] A measuring device for measuring the internal temperature of equipment, differing from Embodiment 1 in that the connector includes an external thread 42 that mates with the internal thread on the cabinet 7, such as... Figure 7 As shown, the external thread 42 is connected to the internal thread on the cabinet 7 by a tapered thread. Since the tapered thread will tighten more and more as it is tightened, the purpose of quick locking is achieved by connecting the external thread 42 to the tapered thread on the cabinet 7.

[0041] The working principle of this utility model is as follows:

[0042] This invention detects the internal temperature of the equipment through the temperature measuring end 1 and transmits the detected data to the control cabinet through the transmission wire 5, thereby realizing the monitoring of the internal temperature of the equipment.

[0043] Temperature measuring end 1 operation: Each temperature measuring end 1 is installed at one end of the transmission wire 5, directly contacting or close to the position where the temperature to be measured is located. The temperature measuring end 1 can sense the temperature change of the surrounding environment and convert it into an electrical signal.

[0044] Signal transmission: The transmission wire 5 is responsible for transmitting the electrical signal collected by the temperature measuring end from inside the equipment to the external control cabinet. In order to ensure the accuracy and stability of signal transmission, the outer surface of the transmission wire 5 is wrapped with a protective layer 2, such as a metal corrugated pipe or a PTFE sleeve, to avoid the pressure and wear on the outer layer of the temperature probe due to the movement of certain moving devices.

[0045] Multi-point measurement and single-point measurement: The embodiment mentions two modes: multi-point measurement and single-point measurement. In the multi-point measurement mode, there is a through hole at the center of the sleeve 4, and the remaining (N-1) through holes are evenly distributed, allowing multiple temperature measuring ends 1 to be arranged at the same time, so as to realize the simultaneous monitoring of temperature at different locations, which helps to more accurately grasp the temperature field distribution inside the disinfection cabinet; while in the single-point measurement mode, only one transmission wire 5 is used to collect temperature data.

[0046] Quick Installation and Fixing: To facilitate installation and maintenance, this utility model employs different connection methods to fix the sleeve 4 and the cabinet 7. For example, the chuck 3 and locking mechanism mentioned in Embodiment 4, and the tapered thread connection method (external thread 42 engaging with the internal thread of the cabinet) in Embodiment 5, both achieve quick installation and fixing, are easy to operate, improve assembly speed, ensure connection stability, and reduce maintenance time and costs.
