Description
Technical Field
[0001] This application relates to the technical field of wire protection devices, and in particular to a wire layout device for sensor ground temperature measurement in cold regions. Background Art
[0002] In alpine seasonal frozen soil areas, due to the influence of winter temperature inside the soil, the phenomenon of freezing in winter and melting in summer may occur, and it is necessary to monitor the ground temperature in real time to determine the temperature at different depths of the frozen soil.
[0003] However, when monitoring deeper frozen soil areas with a large number of measurement points, the wiring of the sensors becomes cumbersome. Since the wiring layout cannot be seen inside the soil mass, it is difficult to determine the disconnected sensor if wire entanglement or wire breakage occurs. Utility Model Content
[0004] The purpose of this application is to provide a wire layout device for sensor ground temperature measurement in cold regions, which can provide protection for the sensor wires and reduce the difficulty of troubleshooting the disconnected sensors.
[0005] An embodiment of this application provides a wire layout device for sensor ground temperature measurement in cold regions, including:
[0006] A protective body, which is a cylindrical structure, is provided with a plurality of assembly holes for installing sensors, having different positions in the longitudinal direction of the cylinder of the protective body and opened on the outer wall of the protective body;
[0007] A plurality of wire ducts are arranged inside the solid part of the protective body, and connect the assembly holes to the ends of the protective body along the longitudinal direction of the cylinder of the protective body.
[0008] Preferably, the protective body includes an inner insulation layer and an outer insulation layer, and the inner insulation layer and the outer insulation layer are arranged alternately inside and outside to form a wire cavity for accommodating the wire ducts, and the outer insulation layer is provided with the assembly holes.
[0009] Preferably, through holes are opened at both ends of the wire duct and are flush with the two ends of the protective body respectively, and through holes connecting the assembly holes are opened on the side wall of the pipe body of the wire duct.
[0010] Preferably, the assembly holes are arranged in a single spiral pattern in the longitudinal direction of the cylinder of the protective body.
[0011] Preferably, the interval between two adjacent assembly holes in the longitudinal direction of the cylinder of the protective body is equal to (H - h) / n, where H is the length of the cylinder of the protective body, h is the distance between the first assembly hole and the non-wire-out end of the protective body, and n is the number of wire ducts.
[0012] Preferably, the inner wall of the assembly hole is provided with threads.
[0013] Preferably, the wiring duct is fixed inside the solid part of the protective body by welding.

[0015] Preferably, the number of the protective bodies is at least two, and the protective bodies are stacked, and the wiring ducts in adjacent two protective bodies are respectively communicated with each other in pairs.
[0016] Preferably, one end of the protective body is provided with a plug-in part, and the other end of the protective body is formed with a recessed part, and adjacent two protective bodies are stacked through the embedded fit of the plug-in part and the recessed part.
[0017] Advantages of the present application: The protective body with a cylindrical structure is used to carry multiple groups of wiring ducts. By opening an assembly hole for installing a sensor on the outer wall of the protective body, the assembly hole is made to communicate with the wiring duct in pairs, so as to connect the assembly hole to the end of the protective body along the length direction of the cylinder of the protective body through the wiring duct. Since the wires connecting each sensor are respectively led out to the ground through the corresponding wiring ducts, when the sensor wiring layout device for cold region ground temperature measurement is buried in the frozen soil area to be detected, the wires can be protected from the influence of low temperature and external factor damage, and at the same time, the wires can be prevented from being entangled. When the wire is disconnected from the sensor, the wires disconnected from the sensor can be checked one by one, reducing the difficulty of checking the sensor where the disconnection occurs.

[0022] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.
[0024] Figure 1 It is a schematic structural diagram of a sensor wiring layout device for cold region ground temperature measurement provided by the first embodiment of the present application. Refer to Figure 1 , the sensor wiring layout device for cold region ground temperature measurement includes a protective body 100 and a plurality of wiring pipes 200.
[0025] The protective body 100 is of a cylindrical structure. The protective body 100 is provided with a plurality of assembly holes 300 for installing sensors, which are located at different positions in the longitudinal direction of the cylindrical body of the protective body 100 and are opened on the outer wall of the protective body 100. In this embodiment, the protective body 100 is a hollow cylindrical structure (in other embodiments, it can also be other cylindrical structures, which is not limited). The outer wall of the protective body 100 is provided with a plurality of assembly holes 300 for installing sensors. The positions of the respective assembly holes 300 in the longitudinal direction of the cylindrical body of the protective body 100 are different, that is, at least two assembly holes 300 are arranged at intervals in the longitudinal direction of the cylindrical body of the protective body 100. For example, when the longitudinal direction of the cylindrical body of the protective body 100 is parallel to the height direction, at least two assembly holes 300 have different height positions.
[0026] The wiring pipe 200 is arranged inside the solid part of the protective body 100. The wiring pipe 200 connects the assembly hole 300 to the end of the protective body 100 along the longitudinal direction of the cylindrical body of the protective body 100. In this embodiment, the wiring pipe 200 is embedded inside the solid part of the protective body 100. The length direction of the wiring pipe 200 is parallel to the longitudinal direction of the cylindrical body of the protective body 100. The wiring pipe 200 is provided with corresponding through holes at positions close to the assembly hole 300 and through holes at positions close to the end of the protective body 100. It can communicate with the assembly hole 300 through the through hole close to the assembly hole 300, and make the assembly hole 300 communicate with the through hole of the wiring pipe 200 close to the end of the protective body 100 through the body of the wiring pipe 200, so as to connect the assembly hole 300 to the end of the protective body 100.
[0027] The sensor wiring arrangement device for geothermal temperature measurement in cold regions is used for wiring protection and installation of temperature sensors. During actual use, the sensor wiring arrangement device for geothermal temperature measurement in cold regions is buried in the frozen soil area to be detected, and the temperature sensors are respectively fixedly installed in each assembly hole 300. Among them, one temperature sensor is correspondingly installed in one of the assembly holes 300, and the wire body connecting the temperature sensor runs along one of the wiring ducts 200 towards the end of the protective body 100 and finally extends out of the protective body 100 through the through hole near the end of the wiring duct 200 at the end of the protective body 100. The extended wire body is connected to the processor, so as to obtain the sensing detection signal of the temperature sensor. Since the positions of the respective assembly holes 300 in the cylinder length direction of the protective body 100 are not the same, when the sensor wiring arrangement device for geothermal temperature measurement in cold regions is buried in the frozen soil area to be detected along the cylinder length direction of the protective body 100, the temperature sensors installed in the assembly holes 300 can detect the temperature of areas at different depths in the frozen soil area to be detected, so as to determine the temperature of areas at different depths in the frozen soil area to be detected. After the sensor wiring arrangement device for geothermal temperature measurement in cold regions is buried in the frozen soil area to be detected, since the wire bodies connecting the respective sensors are respectively led out to the ground through the corresponding wiring ducts 200, the wire bodies can be protected from the influence of low temperature and damage by external factors, and at the same time, the wire bodies can be prevented from being entangled. When the wire body is disconnected from the sensor, the wire bodies disconnected from the sensor can be checked one by one, reducing the difficulty of checking the sensors with disconnection.
[0028] With reference to Figure 1 and Figure 2 In one embodiment, the protective body 100 includes an inner thermal insulation layer 110 and an outer thermal insulation layer 120. The inner thermal insulation layer 110 and the outer thermal insulation layer 120 are arranged alternately inside and outside to form a wiring cavity 130 for accommodating the wiring ducts 200, and the outer thermal insulation layer 120 is provided with assembly holes 300. Specifically, the protective body 100 is a cylindrical structure composed of the inner thermal insulation layer 110 and the outer thermal insulation layer 120. Both the inner thermal insulation layer 110 and the outer thermal insulation layer 120 are cylindrical structures. The outer thermal insulation layer 120 is disposed around the outer wall of the inner thermal insulation layer 110. The inner thermal insulation layer 110 and the outer thermal insulation layer 120 are arranged alternately (the inner thermal insulation layer 110 and the outer thermal insulation layer 120 can be fixedly connected in the wiring cavity 130 by extending connecting arms, or the wiring cavity 130 can be sealed at one of the ends for connection). The spaced space therebetween forms the wiring cavity 130. The wiring ducts 200 are arranged annularly and spaced apart in the wiring cavity 130. The wiring ducts 200 are fixedly connected to the inner thermal insulation layer 110 or fixedly connected to the outer thermal insulation layer 120, and communicate with the assembly holes 300 provided in the outer thermal insulation layer 120. In this embodiment, by setting the protective body 100 as a double-layer thermal insulation and protection structure, the wire body can be further protected from the influence of low temperature and damage by external factors.
[0029] In one embodiment, through holes are provided at both ends of the wire routing duct 200 and are flush with the two ends of the protection body 100 respectively. A through hole communicating with the assembly hole 300 is provided on the side wall of the body of the wire routing duct 200. Specifically, through holes are respectively provided at both ends of the wire routing duct 200. When the wire routing duct 200 is disposed on the protection body 100, the two ends of the wire routing duct 200 are respectively flush with the two ends of the protection body 100, and the length direction of the wire routing duct 200 is parallel to the cylinder length direction of the protection body 100. By providing a corresponding through hole on the side wall of the body of the wire routing duct 200, the through hole on the side wall of the body is close to the assembly hole 300 provided on the protection body 100, so that the lead wire of the sensor can be led to the through hole at any end of the wire routing duct 200 through the through hole on the side wall of the body, achieving the effect of flexibly configuring the direction of the sensor lead wire.
[0030] In one embodiment, the assembly holes 300 are arranged in a single helix along the cylinder length direction of the protection body 100. Specifically, the assembly holes 300 are arranged in a single helix from one end of the protection body 100 to the other end, so that the positions of each assembly hole 300 in the cylinder length direction of the protection body 100 are different, and temperature detection at multiple depth positions in the frozen soil area to be detected can be realized.
[0031] In one embodiment, the interval between two adjacent assembly holes 300 in the cylinder length direction of the protection body 100 is equal to (H - h) / n, where H is the cylinder length of the protection body 100, h is the distance between the first assembly hole 300 and the non-wire-out end of the protection body 100, and n is the number of wire routing ducts 200. Specifically, the opening position of the first assembly hole 300 is that there is a certain interval between the first assembly hole 300 and the non-wire-out end of the protection body 100 (for example, the distance between the first assembly hole 300 and the non-wire-out end of the protection body 100 can be 40 cm). After determining the opening position of the first assembly hole 300, according to the cylinder length of the protection body 100, the distance between the first assembly hole 300 and the non-wire-out end of the protection body 100, and the number of wire routing ducts 200, calculate the interval between two adjacent assembly holes 300 in the cylinder length direction of the protection body 100, so as to determine the opening positions of each assembly hole 300, and make the intervals between any two adjacent assembly holes 300 in the cylinder length direction of the protection body 100 equal.
[0032] In one embodiment, threads are provided on the inner wall of the assembly hole 300. Specifically, corresponding threads are provided on the outer wall of the sensor, and the assembly hole 300 and the sensor are fixed by thread engagement.
[0033] In one embodiment, the wire routing duct 200 is fixed inside the solid part of the protection body 100 by welding.
[0034] In one embodiment, the surface of the protective body 100 is coated with a protective coating, which is a silicate heat-insulating coating. This coating has good fire resistance, stable chemical properties, and strong anti-freeze-thaw cycling ability, and is suitable for internal heat preservation in the soil of seasonal freezing regions, reducing the influence of external conditions on the temperature sensor.
[0035] Figure 3 It is a schematic structural diagram of the sensor wire routing arrangement device for measuring ground temperature in cold regions provided by the second embodiment of the present application. Referring jointly to Figure 1 and Figure 3 , in one embodiment, the number of the protective bodies 100 is at least two, and the protective bodies 100 are stacked, and the wire routing pipes 200 in adjacent two protective bodies 100 are respectively communicated with each other in pairs. Specifically, when the frozen soil area to be detected is relatively deep, at least two protective bodies 100 can be stacked and spliced together, so that the wire routing pipes 200 in adjacent two protective bodies 100 are respectively the same in pairs, so as to detect the temperature at a deeper position of the frozen soil area to be detected. In actual use, after at least two protective bodies 100 are stacked and spliced, they are fixed, and then the sensor is installed in the corresponding assembly hole 300, and the wire body connecting the sensor is led out through at least one wire routing pipe 200. Among them, sensors are respectively installed at intervals on each protective body 100, and the sensors installed on each protective body 100 are staggered, so as to avoid the number of wire bodies led out from the wire routing pipe 200 where the wire finally exits being more than one.
[0036] Referring jointly to Figure 3 and Figure 4 , in one embodiment, a plug-in portion 140 is provided at one end of the protective body 100, and a recessed portion 150 is formed at the other end of the protective body 100. Adjacent two protective bodies 100 are stacked through the embedded cooperation of the plug-in portion 140 and the recessed portion 150. Specifically, when the number of the protective bodies 100 is at least two, the plug-in portion 140 of one of the adjacent two protective bodies 100 is in embedded cooperation with the recessed portion 150 of the other of the adjacent two protective bodies 100, so that the adjacent two protective bodies 100 are stacked.
[0037] In summary, for the sensor wire routing arrangement device for measuring ground temperature in cold regions provided by the embodiments of the present application, the protective body with a cylindrical structure is used to carry multiple groups of wire routing pipes. By opening assembly holes for installing sensors on the outer wall of the protective body, the assembly holes are the same as the wire routing pipes in pairs, so as to connect the assembly holes to the end of the protective body through the wire routing pipes along the length direction of the cylinder of the protective body. Since the wire bodies connecting each sensor are respectively led out to the ground through the corresponding wire routing pipes, when the sensor wire routing arrangement device for measuring ground temperature in cold regions is buried in the frozen soil area to be detected, the wire bodies can be protected from the influence of low temperature and damage by external factors, and at the same time, the wire bodies can be prevented from being entangled. When the wire body is disconnected from the sensor, the wire body disconnected from the sensor can be checked one by one, reducing the difficulty of checking the sensor where the disconnection occurs.
