Description

Technical Field

[0001] This utility model relates to the field of wireless temperature measurement technology, specifically a wireless temperature measurement device for power switchgear. Background Technology

[0002] With the increasing electricity consumption in society, the power grid is also developing and being built at a rapid pace. People's requirements for electrical safety are also getting higher and higher, and temperature measurement has always been a key focus for medium and high voltage electrical equipment. Temperature monitoring points of medium and high voltage electrical equipment are located in environments with high voltage, high current, and strong magnetic fields. Some monitoring points are even located in enclosed spaces. Due to problems such as strong electromagnetic noise, high voltage insulation, and space limitations, conventional temperature measurement methods cannot solve these problems and are therefore unusable. Strap-type intelligent wireless temperature measuring devices have been widely used due to their high safety, low cost, and convenient installation.

[0003] According to CN221325703U, a wireless temperature measuring device is disclosed. This technology discloses "a wireless temperature measuring device comprising: a watchband, a wireless temperature measuring device body fixed to the watchband, a charging plate, and a clamping assembly for pressing the end of the charging plate after it is formed into a loop to prevent it from unfolding back to its original shape; wherein, the clamping assembly comprises: a tension plate, guide posts, elastic elements, and a clamping plate; the tension plate is horizontally arranged on the wireless temperature measuring device body, and several guide posts are vertically arranged through the lower surface of the tension plate on the wireless temperature measuring device body; a clamping plate is horizontally arranged at the end of the guide posts away from the tension plate; and several elastic elements." This technology overcomes the problem that when the charging ring is bent, it has a tendency to unfold back, preventing it from adhering tightly to the device under test and affecting the detection results. Therefore, it provides a wireless temperature measuring device that can overcome the unfolding tendency of the charging ring after it is bent into a loop and adhere tightly to the device under test.

[0004] The above solution uses the elastic force of the elastic element to press the end of the power-collecting plate to prevent it from unfolding back, thus ensuring that the power-collecting plate can fit tightly with the device under test and solving the problem of the power-collecting ring having a tendency to recover after bending. However, long-term use or frequent operation will still cause fatigue or aging of the elastic element, which will affect its elastic performance and stability. In addition, the entire wireless temperature sensor often needs to be replaced after it is damaged or the strap is deformed, which undoubtedly increases the cost and complexity of maintenance and replacement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wireless temperature measuring device for power switchgear. It features a modular design by dividing the temperature measuring mechanism into four components: a fixing component, a binding component, a mating component, and a tightening component. When a single module component ages or deforms, only that module needs to be replaced, without replacing the entire temperature measuring mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wireless temperature measurement device for power switchgear, comprising a wireless temperature sensor, wherein the wireless temperature sensor is equipped with a temperature measuring mechanism for fastening to the device to be monitored, and the temperature measuring mechanism comprises:

[0007] The fixed assembly includes a housing that is fitted and installed outside the temperature measuring mechanism, mounting grooves on both sides inside the housing, a shaft that is rotatably installed in the middle of the mounting groove, a gear fixed to the outer wall of the shaft, a guide rod fixed to both ends inside the cavity, a rack that is slidably installed on the guide rod and meshes with the gear for transmission, a plug fixed to the outer end of the rack, a spring installed on the guide rod, and mounting holes at the four corners inside the housing.

[0008] Secure the components with a soft tape installed between the two ends of the housing, with connectors fixed at both ends of the soft tape;

[0009] The mounting bracket is installed inside the housing, and the mounting head is fixed at each of the four corners of the mounting bracket surface. The mounting head has an insertion hole inside.

[0010] A tightening component is provided on the binding component and is used to tighten it.

[0011] Preferably, the tightening assembly includes an adjusting block mounted on a soft tape, a housing fixed at the inner end of the adjusting block, a spring piece installed inside the housing, and the middle end of the spring piece extending to the outside.

[0012] Preferably, the temperature measuring mechanism further includes a first lock head fixed at the four corners of the inner end surface of the outer shell, a second lock head fixed at the four corners of the surface of the fixing bracket, a first lock hole opened on both sides of the inner end of the connector and cooperating with the first lock head, and a second lock hole opened on both sides of the outer end of the connector and cooperating with the second lock head.

[0013] Preferably, the fixing component further includes a mounting slot inside the housing, and the wireless temperature sensor is installed inside the mounting slot, and several heat dissipation holes are opened on the housing.

[0016] Beneficial effects

[0017] This utility model provides a wireless temperature measurement device for power switchgear. Compared with the prior art, it has the following advantages:

[0018] (1) After the wireless temperature sensor is installed in the mounting slot inside the housing, the rotating shaft drives the gear to rotate, and the gear drives the plug to retract through the rack. Then the fixing bracket is placed on the housing, and the mounting head is inserted into the mounting hole. Then the rotating shaft is released, and the pressure of the guide rod's rebound pushes the rack to drive the plug to insert into the socket, thereby fixing the fixing bracket on the housing and fixing the wireless temperature sensor in the fixing component. Furthermore, after the fixing component and the mating component are fixed, the first lock head and the second lock head are inserted into the first lock hole and the second lock hole respectively, thereby fixing the two ends of the binding component and the two ends of the fixing component. When the fixing component and the mating component fix the wireless temperature sensor inside, the binding component can also be fixed at the same time.

[0019] (2) By dividing the temperature measuring mechanism into four modular components, namely the fixing component, the binding component, the mating component and the tightening component, when a single module component ages and deforms, only that module needs to be replaced, without replacing the entire temperature measuring mechanism; and it can be assembled and used with the appropriate fixing component, binding component, mating component and tightening component according to different specifications of wireless temperature sensors and devices to be monitored, thereby improving the overall applicability.

[0020] (3) After the fastening component is attached to the device to be monitored, hold the fastening component with one hand and pull the fastening component with the other hand to tighten the temperature measuring mechanism onto the device to be monitored; and, by pressing the device to be monitored with the pressure of the spring rebound, ensure that the wireless temperature measuring sensor can be closely attached to the device to be monitored, and ensure that the monitoring results are accurate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution for a wireless temperature measuring device for power switchgear: A wireless temperature measuring device for power switchgear includes a wireless temperature sensor 2, and a temperature measuring mechanism 1 is provided on the wireless temperature sensor 2 for fastening to the device to be monitored. The temperature measuring mechanism 1 includes:

[0029] The fixing assembly 11 includes a housing 111 that is sleeved and installed outside the temperature measuring mechanism 1, mounting grooves 112 that are opened on both sides inside the housing 111, a shaft 114 that is rotatably installed in the middle inside the mounting groove 112, a gear 115 that is fixed to the outer wall of the shaft 114, a guide rod 116 that is fixed at both ends inside the cavity 113, a rack 117 that is slidably installed on the guide rod 116 and meshes with the gear 115 for transmission, a plug 118 that is fixed to the outer end of the rack 117, a spring 119 that is sleeved and installed on the guide rod 116, and mounting holes 1110 that are opened at the four corners of the inner end of the housing 111.

[0030] The binding assembly 12 is installed between the two ends of the housing 111 with a soft tape 121 and a connector 122 that is fixed at both ends of the soft tape 121.

[0031] The mounting bracket 131 is installed inside the housing 111 in conjunction with component 13. Mounting heads 132 are fixed at all four corners of the surface of the mounting bracket 131. Insertion holes 133 are opened inside the mounting heads 132.

[0032] Tightening component 14 is disposed on the binding component 12 and is used to tighten it.

[0033] In this embodiment, after the wireless temperature sensor 2 is installed in the mounting slot 112 inside the housing 111, the rotating shaft 114 drives the gear 115 to rotate. The gear 115 drives the plug 118 to retract via the rack 117, then the fixing bracket 131 covers the housing 111, and the mounting head 132 is inserted into the mounting hole 1110. Then, the rotating shaft 114 is released, and the pressure of the guide rod 116 pushing the rack 117 drives the plug 118 to insert into the socket 133, thereby fixing the fixing bracket 131 to the housing 111. The wireless temperature sensor 2 is fixed in the fixing component 11. Furthermore, by dividing the temperature measuring mechanism 1 into four modular components—fixing component 11, binding component 12, mating component 13, and tightening component 14—only the module needs to be replaced when a single module becomes aged or deformed, without replacing the entire temperature measuring mechanism 1. Moreover, it can be assembled and used with the appropriate fixing component 11, binding component 12, mating component 13, and tightening component 14 according to different specifications of wireless temperature sensors 2 and the devices to be monitored, thereby improving the overall applicability.

[0034] Specifically, the tightening assembly 14 includes an adjusting block 141 mounted on the soft tape 121, a housing 142 fixed at the inner end of the adjusting block 141, a spring 143 installed inside the housing 142, and the middle end of the spring 143 extending to the outside.

[0035] In this embodiment, when the tightening component 14 works with the binding component 12 to bind the wireless temperature sensor 2 in the fixing component 11 to the device to be monitored, the pressure of the spring piece 143 rebounding squeezes the device to be monitored, ensuring that the wireless temperature sensor 2 can be tightly attached to the device to be monitored, thus ensuring accurate monitoring results.

[0036] Specifically, the temperature measuring mechanism 1 also includes a first lock head 15 fixed at the four corners of the inner end surface of the outer shell 111, a second lock head 16 fixed at the four corners of the surface of the fixing bracket 131, a first lock hole 17 opened on both sides of the inner end of the connector 122 and cooperating with the first lock head 15, and a second lock hole 18 opened on both sides of the outer end of the connector 122 and cooperating with the second lock head 16.

[0037] In this embodiment, after the fixing component 11 and the cooperating component 13 are fixed, the first lock head 15 and the second lock head 16 are respectively inserted into the first lock hole 17 and the second lock hole 18, thereby fixing the two ends of the binding component 12 and the two ends of the fixing component 11, so that when the fixing component 11 and the cooperating component 13 fix the wireless temperature sensor 2 inside, the binding component 12 can also be fixed at the same time.

[0038] Specifically, the fixing component 11 also includes a mounting slot 112 opened inside the housing 111, and the wireless temperature sensor 2 is installed inside the mounting slot 112, and a number of heat dissipation holes 1112 are opened on the housing 111.

[0039] In this embodiment, after the wireless temperature sensor 2 is installed inside the mounting slot 112 of the housing 111, it can dissipate heat through the heat dissipation hole 1112 during use.

[0040] Specifically, the fixing assembly 11 also includes an adjustment hole 1111 opened on the outer end surface of the shaft 114 and used for inserting a tool to rotate the shaft 114.

[0041] In this embodiment, the fixing component 11 and the mating component 13 can be disassembled and assembled by inserting a tool into the adjustment hole 1111 and rotating the shaft 114.

[0042] Specifically, both ends of the soft tape 121 are fixed with serrated grooves 3, and both ends of the adjusting block 141 have perforations 4.

[0043] In this embodiment, after the fastening component 12 is fastened to the device to be monitored, one hand holds the tightening component 14 and the other hand pulls the fastening component 12 to tighten the temperature measuring mechanism 1 to the device to be monitored.

[0044] The working principle and usage process of this utility model are as follows: First, after the wireless temperature sensor 2 is installed in the mounting slot 112 inside the housing 111, the tool is inserted into the adjustment hole 1111 and the shaft 114 is rotated. The shaft 114 drives the gear 115 to rotate. The gear 115 drives the plug 118 to retract through the rack 117. Then, the fixing bracket 131 is placed on the housing 111 and the mounting head 132 is inserted into the mounting hole 1110. Then, the rotating shaft 114 is released, and the pressure of the guide rod 116 pushes the rack 117 to drive the plug 118 to be inserted into the socket 133, thereby fixing the fixing bracket 131 on the housing 111, thereby fixing the wireless temperature sensor 2 in the fixing assembly 11.

[0045] Furthermore, after the fixing component 11 is fixed with the mating component 13, the first lock head 15 and the second lock head 16 are respectively inserted into the first lock hole 17 and the second lock hole 18, thereby fixing the two ends of the binding component 12 with the two ends of the fixing component 11, so that when the fixing component 11 and the mating component 13 fix the wireless temperature sensor 2 inside, the binding component 12 can also be fixed at the same time.

[0046] Then, after the fastening component 12 is fastened to the device to be monitored, hold the tightening component 14 with one hand and pull the fastening component 12 with the other hand to tighten the temperature measuring mechanism 1 to the device to be monitored; at the same time, the pressure of the spring 143 rebounding squeezes the device to be monitored to ensure that the wireless temperature measuring sensor 2 can be closely attached to the device to be monitored, and to ensure accurate monitoring results.
