Description

Technical Field

[0001] This utility model belongs to the field of temperature monitoring technology, specifically relating to a temperature monitoring device for heating pipelines. Background Technology

[0002] With social development, more and more areas are installing heating systems, which provide people with a comfortable working and living environment. During the use of heating systems, it is necessary to monitor the temperature of the medium in the heating pipes in order to achieve intelligent temperature regulation.

[0003] Currently, most heating systems use temperature sensors installed directly inside the heating pipes. The test head is in a fixed position, and due to the limited number of sensor models, its length is also limited. For large heating pipes, when the internal medium level is low, the fixed-position test head may not be in direct contact with the liquid surface and may only monitor the ambient temperature, leading to inaccurate temperature monitoring results. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a heating pipe temperature monitoring device. Through the structural design of the auxiliary flow block and the guide tube, the test head of the temperature sensor can always be in contact with the liquid in the heating pipe, thereby improving the accuracy of temperature monitoring.

[0005] A temperature monitoring device for heating pipes includes an auxiliary flow block, a conduit, a temperature sensor, and an air bladder. The auxiliary flow block and the conduit are both located inside the heating pipe. The top end of the conduit extends through the heating pipe. The temperature sensor is connected to the conduit, with its test head located inside the conduit. The air bladder is located inside the conduit and, when inflated, can abut and fix the temperature sensor. The conduit has at least two flow channels, one for liquid inlet and the other for liquid outlet. The auxiliary flow block is located beside the conduit, its side facing the water inlet of the heating pipe forming an arc shape. The auxiliary flow block raises the liquid level in the heating pipe, allowing the liquid to flow into the conduit and contact the test head inside.

[0006] Preferably, the conduit is vertically installed inside the horizontally placed heating pipe, and the auxiliary flow block is located on the side of the conduit facing the water inlet end of the heating pipe.

[0007] Preferably, one of the two guide channels is located on the side of the conduit facing the auxiliary flow block, and the other guide channel is located on the side of the conduit facing the outlet end of the heating pipe; the lowest end of the guide channel facing the auxiliary flow block is lower than the height of the auxiliary flow block, and the highest end is higher than the height of the auxiliary flow block, while the lowest end of the guide channel facing the outlet end of the heating pipe is higher than the lowest end of the test head.

[0008] Preferably, the top of the conduit is provided with a platform equipped with a temperature sensor.

[0009] Preferably, the airbag component includes a ring portion, a protrusion portion, and an inflatable portion, the ring portion, the protrusion portion, and the inflatable portion being internally connected to form an integral structure.

[0010] Preferably, the protrusions are provided in multiple ways, and the multiple protrusions are symmetrically distributed in the inner ring of the annular part. One end of the inflatable part is connected to the outer ring of the annular part, and the other end extends out of the conduit and is connected to an external air source.

[0011] Preferably, it also includes a fixing component, wherein two fixing components are provided oppositely distributed on both sides of the temperature sensor, for fixing the temperature sensor against the ground, and the fixing component is detachably connected to the heating pipe.

[0012] Preferably, the fixing component includes a mounting block, a fixing rod, a screw, an abutment, and a knob. The bottom of the fixing rod is detachably connected to the outer wall of the heating pipe through the mounting block. A horizontally arranged screw is threaded onto the fixing rod. One end of the screw is connected to the abutment, and the other end is connected to the knob.

[0013] The beneficial effects of this utility model are: the heating pipe temperature monitoring device provides a test space for the temperature sensor test head by setting a conduit in the heating pipe, and through the structural design of the auxiliary flow block, when the liquid level in the heating pipe is low, the liquid level can flow into the conduit and contact the test head based on the guiding effect of the auxiliary flow block, so that the test head can always be in contact with the liquid in the heating pipe, thereby improving the accuracy of temperature monitoring.

[0014] The airbag design enhances the stability of the connection between the temperature sensor and the conduit when inflated, while also ensuring the conduit remains airtight. Furthermore, deflating the airbag allows for quick separation of the temperature sensor from the conduit, facilitating sensor inspection and replacement.

[0015] By improving the structural design of the fixed components, the stability of the temperature sensor is further enhanced, allowing the test head to be positioned in the center of the conduit, thus avoiding contact with the inner wall of the conduit and affecting the temperature monitoring results.

[0023] Example 1

[0024] like Figure 1 As shown, a heating pipe temperature monitoring device includes an auxiliary flow block 1, a conduit 2, a temperature sensor 3, and an air bladder component 5. Wherein, as... Figure 3 As shown, the temperature sensor 3 includes a sensor body 301, a test head 302, an information transmission terminal 303, and a connector 304. The bottom of the sensor body 301 is connected to the test head 302 for temperature monitoring via the connector 304. The information transmission terminal 303 for connecting to external devices is installed on the sensor body 301.

[0025] like Figure 1 As shown, the auxiliary flow block 1 and the conduit 2 are both located inside the heating pipe, and the top of the conduit 2 extends through the heating pipe. The temperature sensor 3 is connected to the conduit 2, so that the test head 302 of the temperature sensor 3 is located inside the conduit 2.

[0026] Furthermore, the conduit 2 is vertically installed inside the horizontally placed heating pipe, and the auxiliary flow block 1 is located on the side of the conduit 2 facing the water inlet end of the heating pipe. It is used to raise the liquid level in the heating pipe when the liquid level is low, so that the liquid can contact the test head 302 inside the conduit 2.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, the auxiliary flow block 1 is arc-shaped on the side facing the inlet end of the heating pipe to facilitate the flow of liquid in the pipe. At least two flow guide grooves 201 are provided on the conduit 2, one of which is located on the side of the conduit 2 facing the auxiliary flow block 1, and the other is located on the side of the conduit 2 facing the outlet end of the heating pipe.

[0028] Furthermore, the lowest point of the guide channel 201 facing the auxiliary flow block 1 is lower than the height of the auxiliary flow block 1, and the highest point is higher than the height of the auxiliary flow block 1, which facilitates the introduction of liquid into the conduit 2. At the same time, the lowest point of the guide channel 201 facing the outlet of the heating pipe is higher than the lowest point of the test head 302, which facilitates the contact between the test head 302 and the liquid to achieve temperature monitoring. Figure 1 The middle arrow marker is used to simulate the direction of water flow.

[0029] The structural configuration of the auxiliary flow block 1 and the conduit 2 allows the liquid level in the heating pipe to rise through the auxiliary flow block 1 when it is too low, enabling the liquid to flow into the conduit 2 and contact the test head 302 of the temperature sensor 3. This facilitates the temperature sensor 3's monitoring of the heating pipe's temperature. Furthermore, the position and height of the two guide channels 201 ensure that the liquid flowing into the conduit 2 can flow out smoothly without hindering the normal liquid transport function of the heating pipe.

[0030] In addition, when the liquid level in the heating pipe is higher than the auxiliary flow block 1, the liquid can flow directly into the conduit 2, and the auxiliary flow block 1 will not obstruct the flow of the liquid.

[0031] like Figure 1 , Figure 4 As shown, the temperature sensor 3 is inserted into the conduit 2. The top of the conduit 2 is provided with a platform for mounting the sensor body 301. The connector 304 and the test head 302 are located inside the conduit 2. In order to improve the connection stability between the temperature sensor 3 and the conduit 2, the airbag 5 is set inside the conduit 2, so that the airbag 5 can abut and fix the connector 304 when it is inflated.

[0032] Specifically, such as Figure 4 As shown, the airbag component 5 includes a circular part, a protrusion, and an inflatable part. The internal parts of the circular part, the protrusion, and the inflatable part are interconnected to form an integral structure. Multiple protrusions are provided, symmetrically distributed on the inner ring of the circular part. One end of the inflatable part is connected to the outer ring of the circular part, and the other end extends out of the conduit 2 for easy connection to an external air source.

[0033] When the airbag component 5 is not inflated, the temperature sensor 3 is inserted into the conduit 2, so that the test head 302 is located inside the conduit 2. When the top platform of the conduit 2 contacts the sensor body 301, the connector 304 is located inside the inner ring of the airbag component 5. At this time, air is inflated through the inflation part to the annular part and the protrusion part, so that the airbag component 5 is in the shape of... Figure 4 In the inflated state shown, multiple protrusions abut against the connector 304, allowing the test head 302 to be vertically positioned inside the conduit 2, preventing it from contacting the inner wall of the conduit 2 and affecting the temperature monitoring results. Simultaneously, the air bladder 5 achieves a seal on the conduit 2.

[0034] It should be noted that in order to prevent the airbag component 5 from aging and deforming and affecting the sealing performance, the airbag component 5 can be replaced regularly or a horizontally set heat insulation layer can be installed inside the conduit 2 to reduce the heat transfer of the liquid in the heating pipe to the airbag component 5.

[0035] Example 2

[0036] like Figure 1 , Figure 5 As shown, the structure of this embodiment is basically the same as that of embodiment one, except that this embodiment also includes a fixing component 4. Two fixing components 4 are provided in opposite directions. The two fixing components 4 are detachably connected to the outer wall of the heating pipe, and the two fixing components 4 are located on both sides of the temperature sensor 3.

[0037] like Figure 5 As shown, the fixing component 4 includes a mounting block 401, a fixing rod 402, a screw 403, an abutment 404, and a knob 405. The bottom of the fixing rod 402 is detachably connected to the outer wall of the heating pipe via the mounting block 401. In a specific implementation, the mounting block 401 is connected to the outer wall of the heating pipe via screws.

[0038] A horizontally positioned screw 403 is threaded onto the fixing rod 402. One end of the screw 403 is connected to an abutment 404, and the other end is connected to a knob 405. The surface of the abutment 404 is designed to be elastic and can be made of rubber to easily adapt to the irregular surface of the temperature sensor 3 and improve the abutment and fixing effect.

[0039] The position of the abutment 404 is adjusted by rotating the knob 405 to drive the screw 403 to rotate, so that the two relatively distributed fixing components 4 can abut and fix the sensor body 301 by relying on the two abutment 404, thereby further improving the stability of the temperature sensor 3.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
