Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering supervision and quality acceptance device. Background Technology

[0002] In the field of water conservancy construction, project quality acceptance is a key link to ensure the safe operation of water conservancy facilities and the rational use of water resources. Water quality testing, as an important part of project quality acceptance, is directly related to the functional performance of water conservancy projects and ecological environment safety. With the continuous increase in the scale and complexity of water conservancy projects, higher requirements are placed on the accuracy, efficiency and continuity of water quality testing.

[0003] Currently, commonly used water quality testing devices for water conservancy projects have many problems in practical applications. On the one hand, when the testing device draws water samples, the mud, sand, impurities, and other contaminants in the water can easily clog the inlet and testing channel, leading to distorted test data and affecting the accuracy of project quality acceptance. On the other hand, traditional testing devices lack effective self-cleaning functions. After long-term use, residual pollutants will adhere to the testing components, affecting not only the testing accuracy but also requiring frequent manual maintenance and cleaning, increasing testing costs and workload, and reducing testing efficiency. Therefore, developing a water conservancy project supervision and quality acceptance device that can achieve simultaneous self-cleaning during the testing process, reduce maintenance frequency, and ensure testing accuracy has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide an engineering quality acceptance device for water conservancy engineering supervision, so as to solve the problems mentioned in the background art, such as water quality testing devices for water conservancy projects being prone to clogging, lacking self-cleaning function, resulting in distorted test data, low testing efficiency, and high maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an engineering quality acceptance device for water conservancy engineering supervision, comprising a top plate, a connecting flange fixedly installed on the upper surface of the top plate, and a storage battery fixedly installed on the upper surface of the top plate, a central motor fixedly installed in the center of the upper surface of the top plate, the lower end of the output shaft of the central motor penetrating through the lower surface of the top plate, and a rotating drum fixedly connected to the lower end of the output shaft of the central motor, an inlet port opened on the outer surface of the lower end of the rotating drum, and a filter plate fixedly installed inside the end of the inlet port facing the outside of the rotating drum, and a maintenance-free testing mechanism provided at the lower end of the rotating drum, which achieves synchronous self-cleaning during the testing process through the intake and discharge of the fluid to be tested;

[0006] The maintenance-free testing mechanism includes: an electric push rod, which is fixedly installed on the inner top surface of the rotating drum, and a piston plate is fixedly connected to the lower end of the electric push rod; a water quality analyzer is fixedly installed on the inner bottom surface of the rotating drum; an inlet check valve is fixedly installed on the inner bottom surface of the rotating drum; an outlet cylinder is fixedly installed inside the lower end of the rotating drum; an outlet check valve is fixedly installed inside the upper end of the outlet cylinder; a rotating blade is installed inside the lower end of the outlet cylinder; an inner ring is fixedly connected to the lower end of the blade's shaft; an outer ring is fixedly installed on the outer surface of the inner ring; and a scraper is fixedly installed on the outer surface of one end of the outer ring.

[0007] Preferably, a gap is left between the upper end face of the rotating cylinder and the lower surface of the top plate, and holes are opened at equal angles on the upper end face of the rotating cylinder.

[0008] Using the above technical solution, the rotating drum can rotate freely under the drive of the central motor. The hole and gap design at the upper end can balance the air pressure inside and outside the rotating drum, ensuring stable fluid flow during water sample intake and avoiding the impact of pressure difference on sampling efficiency.

[0009] Preferably, the liquid inlet is arc-shaped and is set at equal angles on the outer surface of the rotating drum.

[0010] Using the above technical solution, the arc-shaped liquid inlet can guide the water flow into the rotating drum. Combined with the equiangular distribution structure, it significantly improves the uniformity and efficiency of water sample intake, while reducing fluid resistance and energy consumption.

[0011] Preferably, the outer surface of the piston plate is in contact with the inner surface of the rotating cylinder, and the liquid inlet check valve is disposed at an equal angle on the inner bottom surface of the rotating cylinder below the piston plate.

[0012] By adopting the above technical solution, the fitting design between the piston plate and the inner wall of the rotating cylinder can form a sealed cavity, ensuring that a stable fluid pressure is generated when the electric push rod pushes the piston. The one-way valves with equal angle distribution can make the water sample be drawn in evenly from the bottom of the rotating cylinder, avoiding backflow and ensuring the reliability of the detection process.

[0013] Preferably, the outer surface of the blade is in contact with the inner surface of the liquid outlet cylinder, and the liquid outlet cylinder and the rotating cylinder are concentrically arranged.

[0014] By adopting the above technical solution, the blades are fitted to the inner wall of the liquid outlet cylinder and are concentrically arranged, which can ensure that the kinetic energy generated when the water sample is discharged is efficiently transferred to the blades, avoiding leakage or energy loss. At the same time, the concentric structure ensures the smooth operation of the rotating parts and improves the reliability of the self-cleaning mechanism.

[0015] Preferably, the inner ring and the outer ring are concentrically arranged with the rotating cylinder, and the inner ring is located outside the lower end of the liquid outlet cylinder. The scraper is arc-shaped, and the inner surface of the scraper is in contact with the outer surface of the rotating cylinder.

[0016] Using the above technical solution, the concentric layout of the inner ring, outer ring and rotating drum ensures that the scraper always fits the outer surface of the rotating drum when rotating. The inner curved surface of the arc-shaped scraper matches the shape of the outer wall of the rotating drum, which can effectively scrape off the mud and impurities attached to the liquid inlet and the surface of the filter plate, realize dynamic self-cleaning in the detection process, and avoid manual maintenance.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This engineering quality acceptance device for water conservancy project supervision:

[0018] 1. The central motor drives the rotating drum to rotate. The inlet, in conjunction with the filter plate, draws in water samples. The arc-shaped design and evenly distributed inlet improves the efficiency of water sample absorption. The filter plate initially filters impurities. In the maintenance-free detection mechanism, the electric push rod drives the piston plate, which, combined with the inlet and outlet check valves, enables the intake and discharge of water samples. During the detection process, the water flow drives the paddle to rotate when the liquid is discharged, which in turn causes the inner ring, outer ring, and scraper to rotate. The scraper adheres to the outer surface of the rotating drum, effectively removing impurities attached to the outside of the rotating drum and near the inlet, achieving synchronous self-cleaning, avoiding blockage of the inlet and detection channel, and ensuring the accuracy of the detection data.

[0019] 2. The piston plate fits snugly against the inner surface of the rotating cylinder, and the inlet check valves are distributed at equal angles to ensure smooth water sample intake and prevent backflow. The paddle blades fit snugly against the inner surface of the outlet cylinder to ensure smooth liquid discharge. Simultaneously, the outlet cylinder and rotating cylinder are concentrically positioned, and the concentric design of the inner and outer rings ensures stable operation of the rotating components. The water quality analyzer is fixedly installed at the bottom of the rotating cylinder, enabling accurate water sample testing and improving detection precision. Furthermore, the device's self-cleaning function reduces the frequency of manual maintenance and cleaning, lowers testing costs, and improves testing efficiency, providing a reliable guarantee for the quality acceptance work of water conservancy engineering supervision.

[0027] 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.

[0028] Please see Figures 1-6 This utility model provides a technical solution: an engineering quality acceptance device for water conservancy project supervision.

[0029] Example 1: This example discloses: a top plate 1, a connecting flange 2 fixedly installed on the upper surface of the top plate 1, a battery 3 fixedly installed on the upper surface of the top plate 1, a central motor 4 fixedly installed in the center of the upper surface of the top plate 1, and the lower end of the output shaft of the central motor 4 penetrates through the lower surface of the top plate 1, and a rotating drum 5 is fixedly connected to the lower end of the output shaft of the central motor 4. A liquid inlet 6 is opened on the outer surface of the lower end of the rotating drum 5, and a filter plate 7 is fixedly installed inside the end of the liquid inlet 6 facing the outside of the rotating drum 5.

[0030] A gap is left between the upper end face of the rotating cylinder 5 and the lower surface of the top plate 1, and holes are opened at equal angles on the upper end face of the rotating cylinder 5.

[0031] The liquid inlet 6 is arc-shaped and is set at equal angles on the outer surface of the rotating drum 5;

[0032] The connecting flange 2 on the top plate 1 can be used to connect and fix the device to external equipment. The battery 3 powers the entire device. During operation, the central motor 4 starts, and its output shaft drives the rotating drum 5 to rotate. The upper end face of the rotating drum 5 and the lower surface of the top plate 1 are separated by a gap and have holes to ensure that the rotating drum 5 can rotate freely and that the internal pressure of the rotating drum 5 is balanced with the external pressure. The arc-shaped liquid inlets 6 distributed at equal angles on the outer surface of the rotating drum 5, together with the filter plate 7, use pressure to draw the external water sample into the rotating drum 5 during the rotation of the rotating drum 5. The filter plate 7 can intercept larger particles of impurities, preliminarily purify the water sample, and prevent impurities from entering the rotating drum 5 and affecting subsequent testing, thus achieving efficient and preliminarily filtered water sample collection.

[0033] Example 2: This example discloses, based on Example 1, that a maintenance-free detection mechanism is provided at the lower end of the rotating drum 5, which achieves synchronous self-cleaning during the detection process by the intake and discharge of the fluid to be tested;

[0034] The maintenance-free testing mechanism includes: an electric push rod 8, which is fixedly installed on the inner top surface of the rotating drum 5, and a piston plate 9 is fixedly connected to the lower end of the electric push rod 8; a water quality analyzer 10 is fixedly installed on the inner bottom surface of the rotating drum 5; an inlet check valve 11 is fixedly installed on the inner bottom surface of the rotating drum 5; an outlet cylinder 12 is fixedly installed inside the lower end of the rotating drum 5; an outlet check valve 13 is fixedly installed inside the upper end of the outlet cylinder 12; a rotating blade 14 is installed inside the lower end of the outlet cylinder 12; an inner ring 15 is fixedly connected to the lower end of the shaft of the blade 14; an outer ring 16 is fixedly installed on the outer surface of the inner ring 15; and a scraper 17 is fixedly installed on the outer surface of one end of the outer ring 16.

[0035] The outer surface of the piston plate 9 is in contact with the inner surface of the rotating cylinder 5, and the liquid inlet check valve 11 is set at an equal angle on the inner bottom surface of the rotating cylinder 5 below the piston plate 9.

[0036] The outer surface of the blade 14 is in contact with the inner surface of the liquid outlet cylinder 12, and the liquid outlet cylinder 12 and the rotating cylinder 5 are concentrically arranged.

[0037] The inner ring 15 and the outer ring 16 are concentrically arranged with the rotating cylinder 5, and the inner ring 15 is located outside the lower end of the liquid outlet cylinder 12. The scraper 17 is arc-shaped, and the inner surface of the scraper 17 is in contact with the outer surface of the rotating cylinder 5.

[0038] The electric push rod 8 pulls the piston plate 9 upward, creating a negative pressure inside the lower end of the rotating cylinder 5. When the rotating cylinder 5 draws in a water sample through the inlet 6, the electric push rod 8 pushes the piston plate 9 downward. Due to the one-way conduction characteristic of the inlet check valve 11, the water sample inside the rotating cylinder 5 cannot flow out of the inlet check valve 11 at this time, but can only be discharged through the outlet check valve 13 at the upper end of the outlet cylinder 12. When the water sample flows through the outlet cylinder 12, it drives the paddle 14 to rotate. The rotating shaft of the paddle 14 drives the inner ring 15, the outer ring 16, and the scraper 17 to rotate synchronously. The arc-shaped scraper 17, which is in contact with the outer surface of the rotating cylinder 5, will scrape the outer surface of the rotating cylinder 5 and the filter plate 7 to remove the attached impurities, achieving synchronous self-cleaning during the detection process. During the water sample discharge process, the water quality analyzer 10 located on the bottom surface inside the rotating cylinder 5 will perform real-time detection of the water sample and obtain water quality data.

[0039] 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.
