Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically to a water level gauge pipeline mounting bracket. Background Technology

[0002] In the field of water level monitoring for foundation pits, slopes, tailings dams, etc., the installation of water level gauges and piezometers is crucial for accurately obtaining water level data. However, traditional installation methods for water level gauges and piezometers have many shortcomings, which seriously affect the accuracy of monitoring data and the reliability of equipment.

[0003] Specifically, traditional water level gauges and piezometers are typically lowered directly to the bottom of the water level pipe or a specified installation depth via cables. The sensor is installed inside the water level pipe. In this installation method, the sensor diameter is generally around 20mm, while the inner diameter of the water level pipe varies from 40mm to 80mm. Due to the lack of an effective positioning and fixing mechanism, the sensor often cannot be centered inside the water level pipe, and is prone to shaking and swaying. This not only affects the stability of the sensor but may also lead to deviations in the measurement data. Furthermore, when the sensor is installed at the bottom of the water level pipe, there are often impurities such as mud and sand at the bottom. These impurities can easily clog the water permeable holes of the water level gauge or piezometer, causing the equipment to malfunction or the measurement accuracy to drop significantly. Therefore, we need to propose a water level gauge pipeline mounting bracket. Utility Model Content

[0004] The purpose of this utility model is to provide a water level gauge pipeline mounting bracket to solve the problems of difficulty in centering and positioning the sensor and susceptibility to silt blockage in the traditional installation method mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water level gauge pipe mounting bracket includes a water level gauge body, a bracket circular tube, a tapered tube, a centering positioning mechanism, and a water level tube. The bracket circular tube is disposed inside the water level tube, the water level gauge body is installed inside the bracket circular tube, the tapered tube is fixedly installed at the bottom of the bracket circular tube, and the centering positioning mechanism is installed at the bottom of the bracket circular tube. Under the gravity of the water level gauge body, the centering positioning mechanism touches the bottom and unfolds to cooperate with the inner wall of the water level tube to center and fix the water level gauge body.

[0007] Preferably, the centering positioning mechanism includes a support sleeve, one end of which is slidably inserted into the interior of the tapered tube. A configuration block is detachably connected to the bottom of the support sleeve. Four sets of telescopic springs are fixedly installed in a circular array on the outer wall of the support sleeve. One end of each of the four sets of telescopic springs is connected to a side bracket. One end of each of the four sets of side brackets is hinged to a rotating seat. All four sets of rotating seats are fixedly installed on the bottom outer wall of the support tube.

[0008] Preferably, a limiting ring plate is fixedly installed on the top of the support sleeve, and the limiting ring plate is located inside the tapered tube.

[0009] Preferably, the bottom of the configuration block is provided with a countersunk hole, and a bolt is installed inside the countersunk hole. One end of the bolt passes through the countersunk hole and is threaded into the inside of the bottom of the support sleeve.

[0010] Preferably, the end of the side bracket away from the rotating seat is fixedly bonded with a rubber anti-slip pad to increase friction and prevent scratching the inner wall of the water level pipe.

[0011] Preferably, the inner diameter of the support tube is the same as the outer diameter of the water level gauge body, and the water level gauge body is fixed inside the support tube by an interference fit.

[0012] Preferably, the surfaces of the support tube and the tapered tube are coated with polytetrafluoroethylene to prevent metal corrosion, and the support tube and the tapered tube are made of 316L stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of a centering positioning mechanism, automatically unfolds after the centering positioning mechanism at the bottom of the bracket tube touches the bottom under the action of the gravity of the water level gauge body, and closely cooperates with the inner wall of the water level tube, so as to achieve precise centering and fixing of the water level gauge body inside the water level tube. This design effectively solves the problem that the sensor cannot be centered and fixed inside the water level tube in the traditional installation method, and there is shaking and swinging, thus improving the accuracy and stability of water level monitoring.

[0015] 2. The bottom support sleeve and configuration block design in the centering positioning mechanism of this utility model ensures that when the water level gauge body is installed at the bottom of the water level pipe, the support sleeve can support the water level gauge body away from the mud and sand at the bottom of the water level pipe, thereby effectively preventing mud and sand from entering the sensor's water-permeable hole and ensuring the measurement accuracy and service life of the equipment.

[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 1-4 This utility model provides a technical solution:

[0023] A water level gauge pipe mounting bracket includes a water level gauge body 1, a bracket circular tube 2, a tapered tube 3, a centering positioning mechanism 4, and a water level tube 5. The bracket circular tube 2 is disposed inside the water level tube 5, the water level gauge body 1 is installed inside the bracket circular tube 2, the tapered tube 3 is fixedly installed at the bottom of the bracket circular tube 2, and the centering positioning mechanism 4 is installed at the bottom of the bracket circular tube 2. Under the gravity of the water level gauge body 1, the centering positioning mechanism 4 touches the bottom and unfolds to cooperate with the inner wall of the water level tube 5 to center and fix the water level gauge body 1.

[0024] The water level gauge body 1 is securely installed inside the water level tube 5 by the support tube 2, ensuring the stability of the water level gauge body 1 during the monitoring process; this structure realizes the precise installation of the water level gauge body 1 inside the water level tube 5, avoids measurement errors caused by unstable installation, and improves the accuracy of water level monitoring.

[0025] In an optional embodiment: the centering positioning mechanism 4 includes a support sleeve 41, one end of which is slidably inserted into the interior of the tapered tube 3. A configuration block 42 is detachably connected to the bottom of the support sleeve 41. Four sets of telescopic springs 43 are fixedly installed in a ring array on the outer wall of the support sleeve 41. One end of each of the four sets of telescopic springs 43 is connected to a side bracket 44. One end of each of the four sets of side brackets 44 is hinged to a rotating seat 45. All four sets of rotating seats 45 are fixedly installed on the bottom outer wall of the support tube 2.

[0026] It should be noted that the combination of the telescopic spring 43 and the side bracket 44 utilizes the elasticity of the spring and the unfolding function of the side bracket 44 to achieve automatic centering positioning of the water level gauge body 1 within the water level pipe 5. This mechanism is ingeniously designed and compact in structure. Under the gravity of the water level gauge body 1, the centering positioning mechanism 4 can automatically unfold the side bracket 44 after touching the bottom, thus achieving centering positioning without manual intervention, thereby improving installation efficiency and positioning accuracy.

[0027] In an optional embodiment, a limiting ring plate 46 is fixedly installed on the top of the support sleeve 41, and the limiting ring plate 46 is located inside the tapered tube 3.

[0028] It should be noted that the design of the limiting ring plate 46 effectively restricts the sliding range of the support sleeve 41 within the tapered tube 3, preventing the support sleeve 41 from detaching from the tapered tube 3 due to excessive sliding. Simultaneously, the limiting ring plate 46 enhances the connection stability between the support sleeve 41 and the tapered tube 3, improving the overall reliability of the mounting bracket. The limiting ring plate 46 ensures stable sliding and accurate positioning of the support sleeve 41 within the tapered tube 3, thereby improving the overall stability and durability of the mounting bracket.

[0029] In an optional embodiment: a countersunk hole is provided at the bottom of the configuration block 42, and a bolt 47 is installed inside the countersunk hole. One end of the bolt 47 passes through the countersunk hole and is threaded to the inside of the bottom of the support sleeve 41.

[0030] It should be noted that the design of the countersunk hole and bolt 47 makes the connection between the configuration block 42 and the support sleeve 41 more secure and reliable. At the same time, the configuration block 42 can be adapted and adjusted according to the water level gauge body 1 of different weights, which enhances the versatility and adaptability of the device. The bolt 47 passes through the countersunk hole and is threaded to the bottom of the support sleeve 41, which not only realizes the detachable function of the configuration block 42, but also ensures the strength and stability of the connection. This connection method is simple and easy to implement, and is convenient for installation and maintenance.

[0031] In an optional embodiment, a rubber anti-slip pad is fixedly bonded to the end of the side bracket 44 away from the rotating seat 45 to increase friction and prevent scratching the inner wall of the water level pipe 5.

[0032] It should be noted that the design of the rubber anti-slip pad not only increases the friction between the side support 44 and the inner wall of the water level pipe 5, improving the stability of the centering position, but also prevents the side support 44 from scratching the inner wall of the water level pipe 5 during the unfolding process, thus protecting the integrity of the water level pipe 5. The application of the rubber anti-slip pad extends the service life of the water level pipe 5 and reduces maintenance costs.

[0033] In an optional embodiment: the inner diameter of the support tube 2 is the same as the outer diameter of the water level gauge body 1, and the water level gauge body 1 is fixed inside the support tube 2 by an interference fit.

[0034] It should be noted that the interference fit design ensures a tight connection between the water level gauge body 1 and the support tube 2, preventing measurement errors caused by loosening. At the same time, this connection method facilitates the installation and disassembly of the water level gauge body 1, and also improves the connection stability and measurement accuracy between the water level gauge body 1 and the support tube 2, providing reliable data support for water level monitoring.

[0035] In an optional embodiment: the surfaces of the support tube 2 and the tapered tube 3 are coated with polytetrafluoroethylene to prevent metal corrosion, and the support tube 2 and the tapered tube 3 are made of 316L stainless steel.

[0036] It should be noted that the application of PTFE coating effectively prevents metal corrosion of the support tube 2 and tapered tube 3, extending their service life. At the same time, the choice of 316L stainless steel further improves the corrosion resistance and durability of the device, ensuring long-term stable operation.

[0037] Working principle: In the initial state, the side bracket 44 of the centering positioning mechanism 4 is kept in the reset state by the elastic force of the telescopic spring 43, that is, the side bracket 44 retracts inward and does not contact the inner wall of the water level pipe 5. At this time, the entire mounting bracket (including the water level gauge body 1, the bracket round tube 2, the conical tube 3 and the centering positioning mechanism 4) can be smoothly placed into the water level pipe 5.

[0038] Decentralization process:

[0039] As the mounting bracket is lowered into the water level pipe 5, the side bracket 44 remains in its reset state and will not interfere with the inner wall of the water level pipe 5, ensuring a smooth and unobstructed lowering process. When the mounting bracket is lowered to the bottom of the water level pipe 5, the configuration block 42 first contacts the bottom. Due to the gravity of the water level gauge body 1 and the mounting bracket as a whole, the support sleeve 41 begins to slide upward (relative to the tapered tube 3, actually the tapered tube 3 has a downward tendency relative to the support sleeve 41, but the support sleeve 41 appears to slide upward due to the bottom restriction). At the same time, the telescopic spring 43 is compressed. As the support sleeve 41 slides, the side bracket 44 unfolds outward under the elastic force of the telescopic spring 43 (but at this time the gravity is greater than the spring tension, so the actual manifestation is that the support sleeve 41 pushes open the side bracket) until the rubber anti-slip pad at the end of the side bracket 44 is in close contact with the inner wall of the water level pipe 5, that is, the top limiting ring plate 46 of the support sleeve 41 abuts against and supports the bottom of the water level gauge body 1, realizing the centering of the water level gauge body 1.

[0040] After centering and positioning, the water level gauge body 1 is located at the center of the water level tube 5. Due to the support of the bottom support sleeve 41 and the configuration block 42, the water level gauge body 1 is far away from the mud and sand at the bottom of the water level tube 5, preventing mud and sand from entering the sensor water-permeable hole, thereby ensuring the measurement accuracy of the water level gauge.

[0041] In this state, the water level gauge body 1 can stably perform water level monitoring without being affected by installation position deviation or silt blockage. When it is necessary to disassemble or maintain the water level gauge, simply pull the mounting bracket upward. Since the support sleeve 41 loses its bottom support, the elastic force of the telescopic spring 43 will cause the side bracket 44 to automatically reset and disengage from the inner wall of the water level tube 5, so that the mounting bracket can be easily removed from the water level tube 5.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
