Description

Technical Field

[0001] This utility model relates to the field of hydropower engineering, specifically a testing device for building hydropower engineering. Background Technology

[0002] In the field of building hydropower engineering, with the advancement of technology and the increasing demands on engineering, the requirements for the safety and stability of hydropower facilities are becoming increasingly stringent. Accurate water level detection is a crucial aspect of ensuring the safe and stable operation of building hydropower projects.

[0003] For example, Chinese patent CN222364633U discloses a testing device for building water and electricity engineering, including a support column, a testing box installed on the support column, a push rod slidably installed inside the testing box, one end of the push rod extending outside the testing box and connected to a telescopic rod, the bottom end of the telescopic rod connected to a buoyancy ball, and a support mechanism provided on the outer wall of the support column. The support mechanism includes a support plate fixed to the outer wall of the support column, an adjusting strut provided on the support plate, and a positioning cone located at the bottom end of the adjusting strut. This application uses a combination of support column, testing box, push rod, telescopic rod, and buoyancy ball. The extension distance of the telescopic rod is adjusted according to the distance between the water surface and the testing box. At this time, the buoyancy ball floats on the water surface. If the liquid level rises, the buoyancy ball will rise accordingly and push the push rod to move upward inside the testing box. At this time, the rise or fall distance of the water level can be observed according to the movement interval of the scale bar, which is convenient for staff to observe and detect in real time. The structure is simple and easy to maintain.

[0004] However, in practical applications, the detection scenarios of this device are mostly open or semi-open spaces such as foundation pits and reservoirs. The water surface is easily affected by environmental factors, resulting in waves. This causes the buoyancy ball to be in an unstable swaying state during the floating process. This not only makes it difficult for staff to accurately read the water level value through the scale, resulting in a decrease in detection accuracy, but also causes the swaying of the buoyancy ball to cause the telescopic rod to tilt and swing synchronously. The telescopic rod is subjected to non-axial tilting forces for a long time, which can easily lead to fatigue damage and breakage failure. This affects the service life and detection stability of the device, making it difficult to meet the high precision and high reliability requirements of water level detection in building water and electricity projects. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a testing device for building water and electricity engineering. This technical solution solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A detection device for building hydropower engineering includes a base, a support frame fixedly connected to the top of the base, a connecting frame connected to the support frame via a lifting mechanism, a protective cylinder fixedly connected to the end of the connecting frame away from the support frame, the upper and lower ends of the protective cylinder being open, a grid plate fixedly connected to the bottom opening, a circular pontoon located above the grid plate inside the protective cylinder, two vertically arranged guide rods fixedly connected to the top of the circular pontoon, a reinforcing plate fixedly connected to the top of the two guide rods, a horizontal plate fixedly connected to the top opening of the protective cylinder, both guide rods being slidably connected to the horizontal plate, and an early warning mechanism cooperating with the circular pontoon on the protective cylinder.

[0007] Preferably, the lifting mechanism includes a lead screw rotatably connected to the upright frame, and guide rods symmetrically distributed on both sides of the lead screw are fixedly connected to the upright frame. A motor is fixedly connected to the top of the upright frame, the output end of the motor is fixedly connected to the top of the lead screw, the connecting frame is threadedly connected to the lead screw, and the connecting frame is slidably connected to the two guide rods.

[0008] Preferably, the warning mechanism includes a fixed plate fixedly connected to the open end of the top of the protective cylinder, a multi-stage electric telescopic rod fixedly connected to the fixed plate, a pressure sensor fixedly connected to the bottom output end of the multi-stage electric telescopic rod, an alarm fixedly connected to the outer side of the top of the protective cylinder, and the alarm being electrically connected to the pressure sensor.

[0009] Preferably, two linear bearings are fixedly connected inside the cross plate, and both guide rods are slidably connected to the cross plate through the linear bearings.

[0010] Preferably, an arc-shaped plate is fixedly connected to the top edge of the circular pontoon, the outer arc surface of the arc-shaped plate is close to the inner arc surface of the protective cylinder, the outer arc surface of the arc-shaped plate is provided with water level scale lines, a display port corresponding to the arc-shaped plate is fixedly connected to the protective cylinder near the top, a connecting plate is fixedly connected to the top of the arc-shaped plate, and the other end of the connecting plate is fixedly connected to the reinforcing plate.

[0011] Compared with the prior art, this utility model provides a testing device for building water and electricity engineering, which has the following beneficial effects: 1. This utility model, by setting up a protective cylinder with open top and bottom and a bottom grid plate, can not only allow water to enter normally to drive the circular pontoon to float with the water level, but also block the direct impact of waves on the pontoon. At the same time, with the sliding connection structure of two guide rods and the horizontal plate, it further restricts the movement of the pontoon to only the vertical direction, avoids the pontoon from swaying and deviating, and ensures that the water level scale line on the arc plate can be stably displayed through the display port, which greatly improves the accuracy of water level reading. It also eliminates the hidden danger of the telescopic rod being prone to breakage due to tilting force in traditional devices, and extends the service life of the device.

[0012] 2. This utility model combines flexible adjustability with a safety warning function. By driving the lead screw to rotate via a motor, the connecting frame can move up and down along the guide rod, thereby adjusting the height of the protective cylinder to adapt to different depth detection scenarios without additional disassembly and reassembly. At the same time, the warning mechanism on the protective cylinder can adjust the initial position of the pressure sensor via a multi-stage electric telescopic rod. When the water level rises and the circular float touches the sensor, the alarm can issue a timely warning, facilitating rapid response by staff to abnormal water levels and meeting the flexibility and safety requirements of water level detection in building water and electricity projects.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Example 1 Please refer to Figures 1 to 5As shown, a detection device for building water and electricity engineering includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a connecting frame 4 connected to the support frame 2 via a lifting mechanism 3, a protective cylinder 5 fixedly connected to the end of the connecting frame 4 away from the support frame 2, the upper and lower ends of the protective cylinder 5 being open, a grid plate 6 fixedly connected to the bottom opening, a circular float 7 located above the grid plate 6 inside the protective cylinder 5, two vertically arranged guide rods 8 fixedly connected to the top of the circular float 7, a reinforcing plate 9 fixedly connected to the top of the two guide rods 8, a horizontal plate 10 fixedly connected to the top opening of the protective cylinder 5, both guide rods 8 being slidably connected to the horizontal plate 10, and an early warning mechanism 11 cooperating with the circular float 7 is also provided on the protective cylinder 5.

[0017] Those skilled in the art will understand that when the base 1 is fixed at the construction water and electricity engineering testing site, such as next to a foundation pit or reservoir, the base 1 provides stable support for the upright frame 2; the upright frame 2 is connected to the connecting frame 4 through the lifting mechanism 3, and the height of the connecting frame 4 can be adjusted, thereby changing the position of the protective cylinder 5 so that the bottom opening of the protective cylinder 5 corresponds to the water body being tested; the grating plate 6 allows water to enter the protective cylinder 5 normally; the circular float 7 is affected by the buoyancy of the water body and will float up and down with the water level; the guide rod 8 is slidably connected to the horizontal plate 10, which can limit the circular float 7 to move only in the vertical direction and prevent the float from deviating; the warning mechanism 11 works with the circular float 7 to issue a warning when the water level reaches a preset value. The combination of the protective cylinder 5 and the grating plate 6 not only allows water to flow to drive the circular pontoon 7 to float, but also blocks the impact of waves on the pontoon, ensuring the stability of the pontoon's floating. The sliding structure of the guide rod 8 and the horizontal plate 10 further improves the stability of the pontoon's movement, providing a reliable foundation for subsequent water level detection and early warning. At the same time, the overall structure is stably installed through the base 1 and the upright 2, adapting to the outdoor detection environment of building water and electricity projects.

[0018] Example 2 Furthermore, the lifting mechanism 3 includes a lead screw 301 rotatably connected within the upright frame 2. Guide rods 302 symmetrically distributed on both sides of the lead screw 301 are also fixedly connected within the upright frame 2. A motor 303 is fixedly connected to the top of the upright frame 2, and the output end of the motor 303 is fixedly connected to the top end of the lead screw 301. A connecting frame 4 is threadedly connected to the lead screw 301, and the connecting frame 4 is slidably connected to the two guide rods 302. A telescopic protective sleeve is provided on the outside of the lead screw 301.

[0019] Those skilled in the art will understand that after the motor 303 starts, its output end drives the lead screw 301 to rotate. Since the connecting frame 4 is threadedly connected to the lead screw 301, and the connecting frame 4 is simultaneously slidably connected to the guide rod 302, the rotational motion of the lead screw 301 is converted into the linear lifting and lowering motion of the connecting frame 4 along the guide rod 302, thereby driving the protective cylinder 5, which is fixed to the connecting frame 4, to lift and lower synchronously, achieving precise adjustment of the height of the protective cylinder 5. The transmission method of using the motor 303 to drive the lead screw 301 is more labor-saving and efficient than manual adjustment, and can achieve precise control of the height of the protective cylinder 5, adapting to water bodies of different depths. The guide rod 302 prevents rotational deviation during the lifting and lowering of the connecting frame 4, ensuring the stability of the lifting and lowering of the protective cylinder 5, and further improving the adaptability of the device to different detection scenarios.

[0020] Example 3 Furthermore, the warning mechanism 11 includes a fixed plate 1101 fixedly connected to the open end of the top of the protective cylinder 5. A multi-stage electric telescopic rod 1102 is fixedly connected to the fixed plate 1101. A pressure sensor 1103 is fixedly connected to the bottom output end of the multi-stage electric telescopic rod 1102. An alarm 1104 is fixedly connected to the outer side of the top of the protective cylinder 5. The alarm 1104 is electrically connected to the pressure sensor 1103.

[0021] Those skilled in the art will understand that, according to detection requirements, the initial height of the pressure sensor 1103 fixed at its bottom output end can be adjusted by the multi-stage electric telescopic rod 1102 to set a water level warning threshold. When the water level rises, the circular float 7 rises and touches the pressure sensor 1103. The pressure sensor 1103 converts the pressure signal into an electrical signal and transmits it to the alarm 1104 fixed on the outer side of the top of the protective cylinder 5. The alarm 1104 then sounds an alarm upon receiving the signal. The position of the pressure sensor 1103 can be flexibly adjusted by the multi-stage electric telescopic rod 1102, thereby setting different water level warning thresholds to adapt to the water level safety requirements of different scenarios in building water and electricity engineering. The electrical connection between the pressure sensor 1103 and the alarm 1104 enables automatic alarm for abnormal water levels, eliminating the need for real-time staff monitoring, improving the timeliness and safety of detection, and reducing the labor intensity of manual monitoring.

[0022] Example 4 Furthermore, two linear bearings 12 are fixedly connected inside the horizontal plate 10, and both guide rods 8 are slidably connected to the horizontal plate 10 through the linear bearings 12.

[0023] Those skilled in the art will understand that when the circular float 7 moves the guide rod 8 up and down, the guide rod 8 slides along the inner hole of the linear bearing 12. The linear bearing 12 reduces the sliding friction resistance between the guide rod 8 and the horizontal plate 10. The linear bearing 12 significantly reduces the sliding friction between the guide rod 8 and the horizontal plate 10, making the up-and-down movement of the circular float 7 smoother, reducing component wear, and extending the service life of the guide rod 8 and the horizontal plate 10. At the same time, the reduction in sliding resistance ensures that the circular float 7 can float more sensitively with water level changes, improving the sensitivity and accuracy of water level detection.

[0024] Example 5 Furthermore, an arc-shaped plate 13 is fixedly connected to the top edge of the circular pontoon 7. The outer arc surface of the arc-shaped plate 13 is close to the inner arc surface of the protective cylinder 5. A water level scale line 14 is provided on the outer arc surface of the arc-shaped plate 13. A display port 15 corresponding to the arc-shaped plate 13 is fixedly connected to the protective cylinder 5 near the top. A connecting plate 16 is fixedly connected to the top of the arc-shaped plate 13. The other end of the connecting plate 16 is fixedly connected to the reinforcing plate 9.

[0025] Those skilled in the art will understand that the arc-shaped plate 13 moves up and down synchronously with the circular pontoon 7; the water level scale 14 on the outer arc surface of the arc-shaped plate 13 records the corresponding water level height, and the display port 15 facilitates the observation of the water level scale 14 on the arc-shaped plate 13 as it moves with the pontoon; the top of the arc-shaped plate 13 is fixed to the reinforcing plate 9 through the connecting plate 16, which enhances the connection stability between the arc-shaped plate 13 and the guide rod 8 and the circular pontoon 7, ensuring that the arc-shaped plate 13 moves synchronously with the pontoon. By directly observing the water level scale 14 on the arc-shaped plate 13 through the display port 15, the operator can intuitively obtain real-time water level data, making the operation simple.

[0026] In this embodiment, the motor 303, multi-stage electric telescopic rod 1102, pressure sensor 1103, and alarm 1104 used in this application are all existing technologies, and the connections between the components are also existing technologies. Therefore, their connection relationships and principles will not be described in detail here.

[0027] The working principle and usage procedure of this device are as follows: First, the base 1 is fixedly installed at the testing site of the building's water and electricity project, ensuring that the support frame 2 is vertical and stable. Next, the motor 303 is started, and the output end of the motor 303 drives the lead screw 301 to rotate. Since the connecting frame 4 is threadedly connected to the lead screw 301 and slidably connected to the two guide rods 302 inside the support frame 2, the connecting frame 4 moves up and down along the guide rods 302, thereby driving the protective cylinder 5 to rise and fall until the grid plate 6 at the bottom of the protective cylinder 5 is immersed to a suitable depth in the tested water body, at which point the motor 303 is turned off. Subsequently, according to the water level warning requirements, the height of the pressure sensor 1103 at its bottom is adjusted via the multi-stage electric telescopic rod 1102. A warning threshold is set. During the detection process, water enters the protective cylinder 5 through the bottom opening and the grating plate 6. The circular float 7 located above the grating plate 6 floats up and down with the water level due to buoyancy. At the same time, the circular float 7 drives the arc plate 13 to move synchronously. The staff observes the water level scale line 14 on the outer arc surface of the arc plate 13 through the display port 15 to obtain real-time water level data. When the water level rises to the warning threshold, the circular float 7 touches the pressure sensor 1103. The pressure sensor 1103 transmits the signal to the alarm 1104 on the outer side of the top of the protective cylinder 5. The alarm 1104 sounds an alarm to remind the staff to deal with the abnormal water level in time.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
