Description
TECHNICAL FIELD
[0001] The utility model relates to steam pipeline technical field, concretely relates to a steam pipeline displacement monitoring device. BACKGROUND
[0002] The cogeneration system can not only generate electricity but also supply heat, has the comprehensive benefits such as energy saving, improving heat supply quality, increasing power supply, and meets the energy development trend. The heat energy generated by heat source (such as boiler room, geothermal energy, etc.) is transported to user terminal through steam pipeline to meet the heat supply demand of residents, industry and other fields. The steam pipeline is laid in the mode of "mainly buried, supplemented by overhead".
[0003] The existing steam pipeline of backbone network is mostly buried steam pipeline, and a small part is overhead steam pipeline. The overhead steam pipeline is mainly fixed through a fixing device. The fixing device includes a base, supports the steam pipeline through the base, and then sets a fixing sleeve on the base. The steam pipeline is clamped between the base and the fixing sleeve through bolts. When the backbone network is shut down and resumes heat supply, the steam pipeline will displace due to thermal expansion and contraction principle when it is cooled or heated, and will expand or shrink when it is heated. The existing fixing device cannot adapt to the thermal expansion and contraction of the steam pipeline, is easy to damage the steam pipeline, and also cannot monitor the displacement of the steam pipeline. UTILITY MODEL CONTENTS
[0004] The utility model aims at overcoming the above-mentioned problems, and provides a steam pipeline displacement monitoring device. The device can fix the steam pipeline, adapt to the thermal expansion and contraction of the steam pipeline, and monitor the displacement of the steam pipeline.
[0005] The utility model achieves the purpose by the following technical scheme:
[0006] A steam pipeline displacement monitoring device includes a base and at least one displacement monitoring fixing mechanism arranged on the base. The displacement monitoring fixing mechanism includes a clamping assembly for clamping the steam pipeline and a monitoring assembly for monitoring the expansion or contraction of the steam pipeline. Wherein,
[0007] The clamping assembly includes a plurality of clamping pieces distributed in the circumferential direction and sleeved on the steam pipeline, a mounting bolt arranged between two adjacent clamping pieces, and a mounting nut. The shank of the mounting bolt passes through the two clamping pieces and is connected with the mounting nut. The mounting bolt extends in the radial direction of the steam pipeline. A return elastic piece is arranged between the mounting nut and one of the clamping pieces, and between the shank head of the mounting bolt and the other clamping piece.
[0008] The monitoring assembly includes a pressure sensor arranged between the shank head and the return elastic piece.
[0009] The working principle of the steam pipeline displacement monitoring device is as follows:
[0010] When the main network resumes heat supply, the steam pipeline will expand due to heat, and the clamping piece will move outward under the pushing of the steam pipeline, and the reset elastic piece will be compressed. The elastic force of the reset elastic piece can promote the clamping piece to stably clamp the steam pipeline, so as to realize the fixation of the steam pipeline. The pressure sensor will be pressed, and the pressure data obtained through the pressure sensor can reflect the displacement of the steam pipeline, i.e. the expansion displacement. When the main network is shut down, the steam pipeline will shrink due to cooling, and the elastic force of the reset elastic piece can reset the clamping piece to ensure the stable clamping of the steam pipeline. The pressure data of the pressure sensor will also change, and the pressure data will decrease, thereby reflecting the displacement of the steam pipeline, i.e. the shrinkage displacement.
[0011] In an optimal embodiment of the utility model, the clamping piece comprises an arc-shaped sleeve body, a large 7-shaped piece arranged at one end of the arc-shaped sleeve body, and a small 7-shaped piece arranged at the other end of the arc-shaped sleeve body; the mounting bolt and the mounting nut are matched to connect the large 7-shaped piece of one clamping piece and the small 7-shaped piece of the other clamping piece. In the above structure, the arc-shaped sleeve body is convenient to cooperate with the steam pipeline, thereby ensuring the stability of clamping. By arranging the large 7-shaped piece and the small 7-shaped piece, the two clamping pieces are convenient to connect, and the structure is very compact.
[0012] Preferably, the large 7-shaped piece and the small 7-shaped piece each comprise a radial plate and a circumferential plate, one end of the radial plate is connected with the end of the arc-shaped sleeve body, the other end of the radial plate is connected with the end of the circumferential plate, the stud of the mounting bolt passes through the two circumferential plates, and the reset elastic piece is arranged between the mounting nut and the circumferential plate of the small 7-shaped piece and between the bolt head and the circumferential plate of the large 7-shaped piece. By arranging the above structure, the two clamping pieces are convenient to connect, and at the same time, the mounting bolt can extend in the radial direction of the steam pipeline, so that the clamping piece can adapt to the diameter change of the steam pipeline.
[0013] Preferably, the circumferential plate of the large 7-shaped piece is provided with a movable groove, and the stud of the mounting bolt passes through the movable groove and is movably connected with the movable groove. By arranging the movable groove, when the diameter of the steam pipeline changes, the adjacent two clamping pieces can move relatively, and the position of the clamping piece can be adjusted according to the diameter of the steam pipeline.
[0014] Preferably, the reset elastic piece comprises two oppositely arranged disc springs. The disc spring has a shock absorption effect, and the elastic force generated by the disc spring can promote the clamping piece to clamp the steam pipeline, thereby adapting to the diameter change of the steam pipeline and ensuring the fixation of the steam pipeline.
[0015] Preferably, the number of the clamping pieces is four. By arranging four clamping pieces, the steam pipeline can be clamped well.
[0016] Preferably, the number of the displacement monitoring fixing mechanisms is three. By arranging multiple displacement monitoring fixing mechanisms, the clamping stability can be further improved, the steam pipeline can be prevented from loosening, and the pipeline can be well supported.
[0017] Preferably, a rubber sleeve is arranged between the clamping piece and the steam pipeline. By arranging the rubber sleeve, the friction force can be improved, the clamping stability of the clamping piece can be improved, and the steam pipeline can be buffered.
[0018] Preferably, the base is fixedly connected with one of the clamping pieces in the displacement monitoring fixing mechanisms. In the above structure, the base can support and fix the steam pipeline in cooperation with the clamping piece.
[0019] Preferably, the base comprises a seat body, a horizontal plate arranged at the upper end of the seat body, and a vertical plate arranged between the clamping piece and the horizontal plate. By adopting the above structure, the base structure can be more compact, and the displacement monitoring fixing mechanisms can be conveniently installed on the base.

[0033] To enable those skilled in the art to fully understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0034] See Figures 1-4 This embodiment discloses a steam pipeline displacement monitoring device, including a base 1 and at least one displacement monitoring fixing mechanism disposed on the base 1. The displacement monitoring fixing mechanism includes a clamping component for clamping the steam pipeline 2 and a monitoring component for monitoring the expansion or contraction of the steam pipeline 2.
[0035] See Figures 1-10 The clamping assembly includes multiple clamping members 3 distributed circumferentially and sleeved on the steam pipe 2, mounting bolts 4 and mounting nuts 5 disposed between two adjacent clamping members 3, and mounting bolts 4-1 including studs 4-1 and bolt heads 4-2; the studs 4-1 of the mounting bolts 4 pass through two clamping members 3 and are connected to the mounting nuts 5; the mounting bolts 4 extend radially toward the steam pipe 2, and reset elastic members 6 are provided between the mounting nuts 5 and one of the clamping members 3 and between the bolt heads 4-2 of the mounting bolts 4 and the other clamping member 3.
[0036] See Figures 1-8 The monitoring component includes a pressure sensor 7 disposed between the bolt head 4-2 and the reset elastic element 6.
[0037] See Figures 1-10 The clamping member 3 includes an arc-shaped sleeve 3-1, a large 7-shaped member 3-2 disposed at one end of the arc-shaped sleeve 3-1, and a small 7-shaped member 3-3 disposed at the other end of the arc-shaped sleeve 3-1. The mounting bolt 4 and the mounting nut 5 cooperate to connect the large 7-shaped member 3-2 of one clamping member 3 to the small 7-shaped member 3-3 of the other clamping member 3. In the above structure, the arc-shaped sleeve 3-1 facilitates the fit with the steam pipe 2, thereby ensuring the stability of the clamping. By setting the large 7-shaped member 3-2 and the small 7-shaped member 3-3, the connection of the two clamping members 3 is facilitated, and the structure is very compact.
[0038] See Figures 1-10 The large 7-type component 3-2 and the small 7-type component 3-3 have the same structure but different dimensions, with the large 7-type component 3-2 being larger than the small 7-type component 3-3. During connection, the small 7-type component 3-3 is located inside the large 7-type component 3-2.
[0039] See Figures 1-10 Both the large 7-type component 3-2 and the small 7-type component 3-3 include a radial plate 3-231 and a circumferential plate 3-232. The radial plate 3-231 extends radially, and the circumferential plate extends circumferentially. One end of the radial plate 3-231 is connected to the end of the arc-shaped sleeve 3-1, and the other end of the radial plate 3-231 is connected to the end of the circumferential plate 3-232. The stud 4-1 of the mounting bolt 4 passes through the two circumferential plates 3-232. The reset elastic element 6 is disposed between the mounting nut 5 and the circumferential plate 3-232 of the small 7-type component 3-3, and between the bolt head 4-2 and the circumferential plate 3-232 of the large 7-type component 3-2. By setting the above structure, it is convenient to connect the two clamping components 3, and at the same time, it can also ensure that the mounting bolt 4 extends radially towards the steam pipe 2, so that the clamping component 3 can adapt to the diameter change of the steam pipe 2.
[0040] See Figures 1-10 The circumferential plate 3-232 of the large 7-type component 3-2 is provided with a movable groove 3-21. The stud 4-1 of the mounting bolt 4 passes through the movable groove 3-21 and is movably connected to the movable groove 3-21. By setting the movable groove 3-21, when the diameter of the steam pipe 2 changes, it can be ensured that two adjacent clamping components 3 can move relative to each other, and the position of the clamping components 3 can be adaptively adjusted according to the diameter of the steam pipe 2.
[0041] See Figures 1-10The movable groove 3-21 is an elongated groove that extends circumferentially, allowing the mounting bolt 4 to move circumferentially relative to the groove. Simultaneously, the mounting bolt 4 and the elongated groove can move radially relative to each other. The circumferential plate 3-232 of the small 7-type part 3-3 is provided with a mating hole 3-31. The mounting bolt 4 is connected to the mating hole 3-31, and the diameter of the mating hole 3-31 can be the same as the diameter of the stud 4-1 of the mounting bolt 4.
[0042] See Figures 1-8 The reset elastic element 6 includes two oppositely arranged disc springs 6-1. The disc springs 6-1 have a shock absorption function, and the elastic force generated by the disc springs 6-1 can cause the clamping element 3 to clamp the steam pipe 2, thereby adapting to changes in the diameter of the steam pipe 2 and ensuring the fixation of the steam pipe 2.
[0043] See Figures 1-8 The disc spring 6-1 and the pressure sensor 7 are both sleeved on the mounting bolt 4.
[0044] See Figures 1-10 The number of clamping members 3 is four. By setting four clamping members 3, the steam pipe 2 can be well clamped.
[0045] See Figures 1-3 The displacement monitoring and fixing mechanism consists of three components. The purpose of these multiple mechanisms is to further improve clamping stability, prevent the steam pipe 2 from loosening, and provide excellent support for the pipe.
[0046] See Figures 1-3 A rubber sleeve 8 is provided between the clamping member 3 and the steam pipe 2. By providing the rubber sleeve 8, the friction can be increased, thereby improving the clamping stability of the clamping member 3, and at the same time, it can also buffer the steam pipe 2.
[0047] See Figures 1-3 The base 1 is fixedly connected to one of the clamping components 3 in the displacement monitoring and fixing mechanism. In the above structure, the base 1 can play a supporting role, and together with the clamping component 3, it can support and fix the steam pipe 2.
[0048] See Figures 1-3 The base 1 includes a seat body 1-1, a horizontal plate 1-2 disposed on the upper end of the seat body 1-1, and a vertical plate 1-3 disposed between the clamping member 3 and the horizontal plate 1-2. The purpose of adopting the above structure is to make the base 1 structure more compact, and at the same time facilitate the installation of the displacement monitoring and fixing mechanism on the base 1.
[0049] See Figure 1 The steam pipeline displacement monitoring device can be set up in multiple groups, and the multiple groups of steam pipeline displacement monitoring devices are arranged along the steam pipeline 2.
[0050] See Figures 1-10 The working principle of the above-mentioned steam pipeline displacement monitoring device is as follows:
[0051] When the main heating network resumes operation, the steam pipe 2 expands due to heat, pushing the clamping member 3 outward. This compresses the reset elastic member 6, and the elastic force of the reset elastic member 6 ensures that the clamping member 3 can stably hold the steam pipe 2, thus fixing the steam pipe 2. The pressure sensor 7 is compressed, and the pressure data obtained by the pressure sensor 7 reflects the displacement of the steam pipe 2, i.e., the expansion displacement. When the main heating network stops operating, the steam pipe 2 cools down and contracts. The elastic force of the reset elastic member 6 resets the clamping member 3, ensuring the stable clamping of the steam pipe 2. The pressure data received by the pressure sensor 7 also changes, decreasing in pressure, thus reflecting the displacement of the steam pipe 2, i.e., the contraction displacement.
[0052] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
