Description

Technical Field

[0001] The utility model belongs to the technical field of wireless temperature measurement, and specifically relates to a wireless temperature measurement device for a smart community. Background Art

[0002] Smart communities widely use technologies such as the Internet of Things, cloud computing, and mobile Internet, and use a large number of electrical devices in their internal construction. This has also led to an increase in the number of power supply nodes in the area, and the demand for short-distance power transmission has been increasing. For new or improved electrical devices, matching distribution boxes need to be built. These distribution boxes are crowded and require real-time temperature measurement to prevent electrical fires.

[0003] To reduce wiring, each distribution box is equipped with a development board and a wireless communication module for the temperature sensor. The control system using the development board collects the temperature signal monitored by the temperature sensor and sends it to the duty room through the wireless network of the wireless communication module. Each communication host can control several communication slaves in real time.

[0004] The temperature sensor can be quickly disassembled and assembled in the distribution box by using several springs to push the clamps to clamp the temperature sensor from different directions. Conversely, the temperature sensor can be removed by compressing the springs. However, the temperature sensor is still exposed in the distribution box and will face the flames in the event of a fire. The springs and clamps cannot pop out the temperature sensor after being attacked by the flames, causing the part of the temperature sensor in the distribution box to be burned. For this reason, we propose a wireless temperature measurement device for smart communities. Utility Model Content

[0005] The purpose of this utility model is to provide a wireless temperature measuring device for a smart community, which can automatically pop out the temperature sensor when attacked by flames to prevent the part of the temperature sensor in the distribution box from being burned.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A wireless temperature measuring device for a smart community comprises a temperature sensor, wherein the temperature sensor is electrically connected to a communication component, an outer sheath is sleeved on the outside of the temperature sensor, an alignment slide is sleeved on the outside of the outer sheath, the length of the alignment slide is greater than the length of the outer sheath, the outer sheath is a cylindrical structure with an opening at one end, and a plurality of cloth belts are distributed along a circumferential array at the opening, the cloth belts are fixedly connected to the outer sheath, one end of the cloth belts extends out of the alignment slide, a plurality of rubber bands are fixed to the edge of the outer sheath away from the cloth belt, one end of the rubber bands is fixedly connected to the inner edge of the alignment slide away from the cloth belt, and when working, the detection end of the temperature sensor is moved along the temperature measuring The hole is inserted into the distribution box, the port of the collimated sliding tube is aligned with the temperature measuring hole and fixed with screws, one end of the cloth belt extends to the inner wall of the distribution box and fixed with screws, so that the outer sheath tube is suspended at the temperature measuring hole, and the temperature signal inside the distribution box is monitored in real time through the temperature sensor, and the temperature signal is sent to the communication host along the communication component in the wireless network. Once a fire occurs, the flame of the deflagration will burn out each cloth belt, so that the outer sheath tube is only pulled by the rubber band in the horizontal direction, and slides outward along the collimated sliding tube to leave the distribution box. When attacked by flames, the temperature sensor can be automatically popped out to prevent the part of the temperature sensor in the distribution box from being burned, which can reduce the loss of the wireless temperature measuring equipment when a fire occurs in the distribution box.

[0008] The communication component includes a development board electrically connected to the temperature sensor, a wireless communication module is installed on the development board, and the development board has a preset program to receive the temperature signal detected by the temperature sensor and send it to the communication host along the wireless network where the wireless communication module is located.

[0009] An aerogel bushing is fixed to the inner wall of the outer sheath tube, and the aerogel bushing is sleeved on the outside of the temperature sensor, the development board and the wireless communication module. The deformation of the aerogel bushing is used for shock absorption, so that the temperature sensor, the development board and the wireless communication module work in a relatively safe environment. The aerogel bushing has certain heat insulation properties, which can reduce the adverse effects of the deflagration flame on the temperature sensor, the development board and the wireless communication module.

[0010] One end of the wireless communication module away from the temperature sensor is electrically connected to an antenna rod, one end of which passes through the aerogel sleeve and the outer sheath. The antenna rod enhances the signal of the wireless communication module outside the outer sheath, reduces the shielding effect of the outer sheath on the wireless communication module, and makes the wireless communication interaction more reliable.

[0011] A plurality of protective plates are distributed in a circular array on one side of the outer sheath tube with the antenna pole as the center. The protective plates are fixedly connected to the outer sheath tube. The plurality of protective plates surround the antenna pole from the outside. Once the outer sheath tube falls, the protective plates are grounded and will not directly hit the antenna pole.

[0012] The inner wall of the collimating slide tube is provided with a plurality of slide grooves along the axial direction, and the outer surface of the outer sheath tube partially extends into the slide groove to guide the outer sheath tube and facilitate the outer sheath tube to be separated from the slide groove, so that the outer sheath tube drives the temperature sensor to go straight in and out of the collimating slide tube 3 without deflection and twisting of the wires.

[0013] The technical effects achieved by this utility model are:

When attacked by flames, the temperature sensor can be automatically popped out to prevent the part of the temperature sensor in the distribution box from being burned, thereby reducing the loss suffered by the wireless temperature measuring device when a fire occurs in the distribution box.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0023] like Figure 1-4 As shown, a wireless temperature measuring device for a smart community includes a temperature sensor 1. The temperature sensor 1 can select an HG-T01 fiber grating temperature sensor. The temperature sensor 1 is electrically connected to a communication component. An outer sheath 2 is provided on the outside of the temperature sensor 1. An outer sheath 2 is provided on the outside of the collimation slide tube 3. Both the outer sheath 2 and the collimation slide tube 3 can be made of stainless steel. The length of the collimation slide tube 3 is greater than the length of the outer sheath 2. The outer sheath 2 is a cylindrical structure with an opening at one end, and a plurality of cloth tapes 5 are distributed along a circumferential array at the opening. The cloth tapes 5 are all fixedly connected to the outer sheath 2. One end of the cloth tapes 5 extends out of the collimation slide tube 3. A plurality of rubber bands 4 are fixed to the edge of the outer sheath 2 away from the cloth tape 5. One end of the rubber bands 4 is fixedly connected to the inner edge of the collimation slide tube 3 away from the cloth tape 5. A temperature measuring hole is pre-opened on one side of the distribution box. When working, the detection end of the temperature sensor 1 is inserted into the distribution box along the temperature measuring hole. The port of the collimation slide tube 3 is aligned with the temperature measuring hole. The outer sheath tube 2 is then pulled out of the alignment slide tube 3 and the temperature sensor 1 is automatically ejected when the flame is attacked.

[0024] During installation, it is required that at least one side of the distribution box has a large enough space for horizontally placing the alignment slide tube 3 and a space sufficient for the outer sheath tube 2 to be detached.

[0025] Among them, the cloth tape 5 can be made of vinylon fiber material, which softens and shrinks when close to the flame. The flame is very small and will not explode in the distribution box. It has little harm to electrical components. The remaining collimation slide tube 3 is still fixed on the distribution box. Its stainless steel material can withstand a certain flame. At the same time, the temperature sensor 1 and the communication component are connected to the distribution box with wires and directly connected to the power supply. This wire is long enough to allow the temperature sensor 1 and the outer sheath 2 to slide out of the collimation slide tube 3 smoothly without getting stuck.

[0026] like Figure 1 and Figure 5As shown, the communication component includes a development board 6 electrically connected to the temperature sensor 1. The development board 6 is also connected to the power supply of the distribution box with a sufficiently long wire. The development board 6 can use the AM335x industrial core board, support the RS485 interface, and is connected to the temperature sensor 1 through an optical fiber jumper. A wireless communication module 7 is installed on the development board 6. The wireless communication module 7 can use a 4G-DTU wireless remote transmission module, support the RS485 interface, and the development board 6 has a preset program to receive the temperature signal detected by the temperature sensor 1 and send it to the communication host along the wireless network where the wireless communication module 7 is located.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, an aerogel bushing 8 is fixed to the inner wall of the outer sheath 2, and the aerogel bushing 8 is sleeved on the outside of the temperature sensor 1, the development board 6 and the wireless communication module 7. The deformation of the aerogel bushing 8 is used for shock absorption, so that the temperature sensor 1, the development board 6 and the wireless communication module 7 work in a relatively safe environment. In addition, the aerogel bushing 8 has certain heat insulation properties, which can reduce the adverse effects of the deflagration flame on the temperature sensor 1, the development board 6 and the wireless communication module 7.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, one end of the wireless communication module 7 away from the temperature sensor 1 is electrically connected to an antenna rod 9, one end of the antenna rod 9 passes through the aerogel sleeve 8 and the outer sheath 2, and the antenna rod 9 enhances the signal of the wireless communication module 7 outside the outer sheath 2, reduces the shielding effect of the outer sheath 2 on the wireless communication module 7, and makes the wireless communication interaction more reliable.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a plurality of protective plates 10 are distributed in a circular array on one side of the outer sheath 2 with the antenna rod 9 as the center. The protective plates 10 are all fixedly connected to the outer sheath 2. The plurality of protective plates 10 surround the antenna rod 9 from the outside. Once the outer sheath 2 falls, it is grounded by the protective plates 10 and will not directly hit the antenna rod 9.

[0030] like Figure 2 and Figure 3 As shown, a plurality of slide grooves 11 are opened axially on the inner wall of the collimating slide tube 3, and the outer surface portion of the outer sheath tube 2 extends into the slide groove 11 to guide the outer sheath tube 2 and facilitate the outer sheath tube 2 to separate from the slide groove 11, so that the outer sheath tube 2 drives the temperature sensor 1 to move straight in and out of the collimating slide tube 3 without deflection or twisting of the wires.

[0031] The working principle of the utility model is: when working, the detection end of the temperature sensor 1 is inserted into the distribution box along the temperature measuring hole, the end of the alignment slide tube 3 is aligned with the temperature measuring hole and fixed with screws, one end of the cloth tape 5 is extended to the inner wall of the distribution box and fixed with screws, so that the cloth tape 5 tightens the outer sheath tube 2, and then the rubber band 4 is used to tighten the outer sheath tube 2 inside the alignment slide tube 3, the rubber band 4 is stretched and the elastic deformation increases, so that the outer sheath tube 2 is suspended at the temperature measuring hole, and a plastic plate can be used to close the opening of the outer sheath tube 2 to seal the communication component, and the opening of the plastic plate is used to expose the temperature sensor 1.

[0032] Then, the temperature signal inside the distribution box is monitored in real time through the temperature sensor 1, and the temperature signal is sent to the communication host along the communication component in the wireless network. Once a fire occurs, the flame of the explosion will burn each cloth belt 5, so that the outer sheath tube 2 is only pulled in the horizontal direction by the rubber band 4, and slides outward along the alignment slide tube 3 to leave the distribution box. When attacked by flames, the temperature sensor 1 can be automatically popped out to prevent the part of the temperature sensor 1 in the distribution box from being burned, which can reduce the loss of the wireless temperature measuring equipment when a fire occurs in the distribution box.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
