Description

Technical Field

[0001] This utility model relates to the field of dam grouting data pipe support technology, specifically a pipe support device for synchronous recording of dam grouting data. Background Technology

[0002] During dam grouting, accurate real-time recording of key data such as grouting pressure, flow rate, and grout injection volume is crucial for assessing grouting quality, identifying changes in the dam's internal structure, and guiding subsequent construction adjustments. However, existing data recording methods largely rely on manual, timed observation and recording, which is not only inefficient but also prone to significant human error. Manual observation makes it difficult to achieve continuous real-time monitoring of data. When abnormal fluctuations occur in grouting pressure or flow rate, it is difficult to detect them promptly and take appropriate measures, thus affecting the accuracy of grouting quality. Furthermore, the installation and fixing of grouting pipes typically employ simple temporary support structures, which often lack sufficient stability and precise positioning capabilities.

[0003] During the operation of the dam grouting data synchronous recording instrument, it is necessary to first achieve precise docking with the pre-set holes in the dam body. Then, relying on the instrument's sensing system, the real-time flow rate of the grout inside the dam body is dynamically monitored and recorded. However, in long-term daily use, impurities such as tiny particles and mineral deposits in the grout gradually accumulate on the inner wall of the pipe, forming a difficult-to-remove scale layer. These impurities not only change the actual diameter of the pipe but also interfere with the stable flow state of the fluid, causing deviations between the flow rate data collected by the instrument's sensing components and the actual value. This severely reduces the accuracy of the flow rate recording and consequently affects the reliability of the dam grouting effect assessment. Utility Model Content

[0004] The purpose of this invention is to provide a pipe support device for synchronous recording of grouting data in dams, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a pipe support device for synchronous recording of dam grouting data, including a pipe, a pipe wall cleaning mechanism inside the pipe, and a positioning and installation mechanism on one side of the pipe.

[0006] The pipe wall cleaning mechanism includes a first connecting rod rotatably connected to the inner wall of the pipe. A disc is fixedly connected to the middle of the outer wall of the first connecting rod. Impellers are fixedly connected to both sides of the disc. Cams are fixedly connected to both ends of the outer wall of the first connecting rod. Two baffles are fixedly connected to both sides of the inner wall of the pipe. A second connecting rod is fixedly connected between each pair of opposing baffles. A scraper is fixedly connected to one end of each of the two second connecting rods.

[0007] In one example, springs are fitted on the outer walls of both second connecting rods, and limit plates are fixedly connected to the other ends of both second connecting rods.

[0008] In one example, a protective plate is fixedly connected between every two opposing baffles.

[0009] In one example, support rods are fixedly connected to both sides of the outer wall of the first connecting rod, and a cutter is fixedly connected between the two support rods.

[0010] In one example, the positioning and installation mechanism includes a mounting plate fixedly connected to one side of the pipe. A through hole is provided on one side of the mounting plate. Connecting rods are fixedly connected to both sides of the inner wall of the through hole. A partition is rotatably connected between the two connecting rods. A torsion spring is embedded on one side of each of the two connecting rods.

[0011] In one example, a pressure tapping pipe is fixedly connected to one side of the top of the pipe, and a detection recorder is fixedly connected to the top of the pressure tapping pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The pipeline is installed on the dam body via an mounting plate. During use, when the pipeline detects the flow rate within the dam body, a first connecting rod is installed inside the pipeline. A disc is located in the middle of the first connecting rod, and impellers are located on both sides of the disc. The impellers rotate under the action of water flow, which in turn drives the cams located on both sides of the first connecting rod to rotate. Two baffles are located at the front of the cams, and a second connecting rod is located between the two baffles. A scraper is installed at one end of the second connecting rod. The rotation of the cams displaces the second connecting rod on one side, thereby driving the scraper to clean the inner wall of the pipeline. This prevents impurities from adhering to the inner wall of the pipeline, which could lead to inaccurate data during recording. Springs are installed on the outer walls of the two second connecting rods. The function of the springs is to repeatedly scrape the scraper on one side, so that, with the cooperation of the cams and springs, the scraper reciprocates inside the pipeline, making the cleaning process more thorough.

[0014] 2. When installing the bracket, a mounting plate is provided on one side of the pipe, and a through hole is provided on one side of the mounting plate. A baffle is rotatably connected inside the through hole via a connecting rod. The function of the baffle is that when the pipe is not installed in the corresponding position, the baffle will be in a vertical state, which will block the water flow, so that it can be determined by observation and detection instruments whether it is installed in the designated position. When it is installed in the designated position, the baffle will be in a released state under the action of the torsion spring, and thus will not block the water flow. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a pipe support device for synchronous recording of dam grouting data, including a pipe 1, a pipe wall cleaning mechanism 2 inside the pipe 1, and a positioning and installation mechanism 3 on one side of the pipe 1;

[0023] The pipe wall cleaning mechanism 2 includes a first connecting rod 201 rotatably connected to the inner wall of the pipe 1. A disc 202 is fixedly connected to the middle of the outer wall of the first connecting rod 201. Impellers 203 are fixedly connected to both sides of the disc 202. Cams 204 are fixedly connected to both ends of the outer wall of the first connecting rod 201. Two baffles 205 are fixedly connected to both sides of the inner wall of the pipe 1. A second connecting rod 206 is fixedly connected between each pair of opposing baffles 205. A scraper 208 is fixedly connected to one end of each of the two second connecting rods 206.

[0024] Springs 207 are fitted on the outer walls of both second connecting rods 206, and limit plates 212 are fixedly connected to the other ends of both second connecting rods 206.

[0025] In use, pipe 1 is installed on the dam body via mounting plate 301. During operation, when pipe 1 detects the flow rate in the dam body, a first connecting rod 201 is installed inside pipe 1. A disc 202 is located in the middle of the first connecting rod 201, and impellers 203 are located on both sides of the disc 202. The impellers 203 rotate under the action of water flow, which in turn drives the cams 204 located on both sides of the first connecting rod 201 to rotate. Two baffles 205 are located at the front of the cams 204, and a second connecting rod 206 is located between the two baffles 205. One end is equipped with a scraper 208. Under the rotation of the cam 204, the second connecting rod 206 on the pushing side is displaced, thereby driving the scraper 208 to clean the inner wall of the pipe 1. This prevents impurities from adhering to the inner wall of the pipe 1, which would cause inaccurate data during the recording process. Furthermore, springs 207 are provided on the outer walls of the two second connecting rods 206. The function of the springs 207 is to repeatedly scrape the scraper 208 on one side, so that with the cooperation of the cam 204 and the springs 207, the scraper 208 moves back and forth inside the pipe 1, making the cleaning process more thorough.

[0026] Furthermore, a protective plate 209 is fixedly connected between every two opposing baffles 205;

[0027] The protective plate 209 located on one side of the two baffles 205 can protect the spring 207 and prevent impurities such as aquatic plants from sticking to its exterior.

[0028] Furthermore, support rods 210 are fixedly connected to both sides of the outer wall of the first connecting rod 201, and a cutter 211 is fixedly connected between the two support rods 210.

[0029] The cutter 211 located on one side of the impeller 203 can rotate together with the first connecting rod 201, thereby cutting the aquatic plants and preventing the impeller 203 from becoming entangled and stopping its rotation.

[0030] Furthermore, the positioning and installation mechanism 3 includes a mounting plate 301 fixedly connected to one side of the pipe 1. A through hole 302 is provided on one side of the mounting plate 301. Connecting rods 303 are fixedly connected to both sides of the inner wall of the through hole 302. A partition plate 304 is rotatably connected between the two connecting rods 303. A torsion spring 305 is embedded on one side of each of the two connecting rods 303.

[0031] When the bracket is installed, a mounting plate 301 is provided on one side of the pipe 1. A through hole 302 is provided on one side of the mounting plate 301. A baffle 304 is rotatably connected inside the through hole 302 through a connecting rod 303. The function of the baffle 304 is that when the pipe 1 is not installed in the corresponding position, the baffle 304 will be in a vertical state, which will block the water flow. This allows the monitoring instrument to determine whether it is installed in the designated position. When it is installed in the designated position, the baffle 304 will be in an open state under the action of the torsion spring 305, and will not block the water flow.

[0032] Furthermore, a pressure tapping pipe 4 is fixedly connected to one side of the top of pipe 1, and a detection recorder 5 is fixedly connected to the top of pressure tapping pipe 4.

[0033] The pressure tapping pipe 4 located at the top of pipe 1 is connected to the detection recorder 5, which can be used to judge and record the water flow rate.
