[0002] High dam and large reservoir projects are needed for the comprehensive utilization of water resources and the development of hydropower resources. With the vigorous development of my country's hydropower industry in the past 20 years, a large number of high dams or super high dams have been built one after another, and the construction of the dam body needs to be controlled by the spillway structure. Among them, the spillway structure has been subjected to the influence of various environmental loads such as high-speed water flow, freezing, temperature, earthquake, etc. for a long time. A series of complex working environments often cause the spillway structure to produce structural damage due to corrosion and fatigue, and these damages often exist in the underwater position of the structure and are not easy to be directly found. Under the excitation of high-speed water flow, the structural damage will further expand and may even cause the loss of the function of the entire structure. Therefore, it is necessary to use a detection device to perform real-time scanning and detection of the gate of the spillway structure. In the prior art, the detection of the spillway structure mostly adopts manual on-site detection or on-site detection using drones. This detection will undoubtedly consume manpower and material resources, and cannot be detected in real time. The long-term use of the spillway structure requires real-time detection. If the spillway structure cannot be detected in time, it will seriously affect the normal use of the dam body, resulting in leakage, which will affect personal safety.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Please refer to Figure 1-Figure 12 As shown, the present invention provides a construction quality inspection device, comprising a dam body 1 and a fixed column 11, wherein the fixed column 11 is fixedly connected to the top surface of the dam body 1, and a flow channel 12 for discharge is opened on the dam body 1;

[0035] A slide bar 4 is slidably arranged at one side of the dam body 1 corresponding to the flow channel opening 12, and first limit sliders 61 are fixedly arranged at both ends of the slide bar 4. A limit rod 6 arranged parallel to the slide bar 4 is arranged between adjacent first limit sliders 61.

[0036] A roller 5 is slidably arranged on the periphery of the slide bar 4, and a pulling mechanism for pulling the roller 5 to rotate and swing is arranged between the roller 5 and the limit rod 6;

[0037] A detection mechanism for scanning and detecting the gate plate in the flow channel opening 12 is arranged on the periphery of the drum 5 .

[0038] In the present case, a flow outlet 12 for discharging water is provided on the dam body 1, and a gate plate for blocking the flowing water is provided in the flow outlet 12, and the gate plate is opened to facilitate the discharge of water, wherein, through the up and down sliding setting of the slide bar 4, the first limit slider 61 and the limit rod 6 can be driven to slide accordingly, the limit rod 6 and the slide bar 4 slide synchronously, and the limit rod 6 and the slide bar 4 are in a parallel state, and a roller 5 is provided to slide left and right around the periphery of the slide bar 4, and a pulling mechanism is provided between the limit rod 6 and the roller 5, when the roller 5 slides left and right around the periphery of the slide bar 4, one end of the pulling mechanism will slide along the periphery of the limit rod 6, and the pulling mechanism can make the roller 5 in a rotating and swinging state during the sliding process, and the rotating swing of the roller 5 can drive the detection mechanism to be in a swinging state, and the gate plate in the flow outlet 12 can be scanned and detected in real time through the detection mechanism.

[0039] Among them, through the left and right sliding setting of the roller 5, and the ability to rotate and swing, the detection mechanism can be put into a sliding and rotating swinging state, and the gate plate in the convection channel 12 can be scanned and detected during the sliding of the slide bar 4, and the state of the gate plate can be detected to ensure normal discharge. No manual on-site inspection or drone inspection is required. The quality of the gate plate of the discharge structure in the convection channel 12 can be inspected in real time on the sliding site of the slide bar 4 to ensure the quality of the gate plate structure. If corrosion occurs, it can be dealt with in time to improve safety performance.

[0040] Among them, the detection of the gate plate in the flow channel 12 has the following effects:

[0041] 1. Prevent the risk of dam break: The gate plate in the flow channel 12 of the dam body 1 is a key component for controlling the outflow of water. By testing the gate plate, its normal operation can be ensured to prevent the gate plate from being unable to close normally due to aging, damage, etc. If the gate plate cannot be closed effectively, when the water level of the reservoir or dam is high, a large amount of water may flow out uncontrollably, causing a sudden change in the pressure on the dam body 1, thereby increasing the risk of dam break. For example: During the flood period, the gate plate needs to be able to open and close accurately according to the dispatching instructions to adjust the water level of the reservoir and ensure that the dam safely passes the flood period.

[0042] 2. Ensure downstream safety: The state of the gate at the flow outlet 12 of the dam body 1 directly affects the safety of the downstream area. A normally operating gate can reasonably control the discharge volume to avoid flood disasters in the downstream area due to sudden large-scale water discharge. For downstream areas such as residential areas, farmland irrigation facilities, and major traffic routes, accurate detection of the performance and state of the gate can detect potential safety hazards in advance and ensure the safety of the downstream ecological environment, infrastructure, and people’s lives and property.

[0043] 3. Improve the efficiency of water resource utilization: Testing the gate can detect whether there is leakage; if the gate is not sealed tightly, it will lead to waste of water resources. Timely detection and repair of gate leakage can reduce this unexpected water loss, thereby improving the efficiency of the entire water resource utilization system, whether it is used for agriculture, industry or urban water supply.

[0044] 4. Extend the service life of equipment: Regular inspection of the gate can timely discover problems such as wear and corrosion of the gate; for the metal parts of the gate, long-term contact with water is prone to rust and corrosion. Through inspection, anti-corrosion measures can be taken as early as possible, such as repainting, replacing corroded parts, etc. For the moving parts of the gate, such as hinges, screws, etc., inspection can discover their wear and tear, and timely lubricate or replace them, thereby extending the service life of the gate equipment and reducing the cost of equipment renewal.

[0045] Among them, the gate plate is detected by scanning detection method. The scanning detection method has a penetrating effect and can scan and detect the gate plate finely to ensure the normal state of the gate plate.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 and Fig.12 As shown, the dam body 1 on both sides of the flow channel opening 12 is provided with a first slide groove 13 for the slide rod 4 to slide up and down, the cross-section of the first slide groove 13 is a cross-shaped structure, the first limit slider 61 is slidably set in the first slide groove 13, and the dam body 1 is provided with a receiving groove 14 connected to the first slide groove 13.

[0047] The slide bar 4 is provided with an adjustment mechanism for driving the roller 5 to slide left and right. The adjustment mechanism includes a reciprocating screw 7, a gear 71, a third limit slider 72 and a limit connecting strip 721. The third limit slider 72 is slidably arranged in the slide bar 4, and the third limit slider 72 is threadedly connected to the reciprocating screw 7. One end of the reciprocating screw 7 passes through the slide bar 4 and is fixedly connected to the gear 71. A gear rod 141 meshing with the gear 71 is fixedly connected in the accommodating groove 14. The periphery of the third limit slider 72 is fixedly connected to the limit connecting strip 721. One end of the limit connecting strip 721 is arranged in the roller 5. A limit rolling groove 52 is provided in the roller 5. One end of the limit connecting strip 721 is rollingly arranged in the limit rolling groove 52, and both sides of the limit connecting strip 721 abut against both sides of the inner wall of the limit rolling groove 52. A second sliding groove 41 is provided on the periphery of the slide bar 4 for the limit connecting strip 721 to slide left and right.

[0048] The first slide groove 13 is provided to facilitate the sliding of the slide bar 4 up and down, and the slide bar 4 is limited to avoid the slide bar 4 from derailing during the sliding process. The gear rod 141 is provided so that when the slide bar 4 slides in the first slide groove 13, the roller 5 and the detection mechanism will be driven to slide, and the reciprocating screw 7 can be driven to slide in the first slide groove 13. A receiving groove 14 for fixedly receiving the gear rod 141 is provided on the dam body 1, and the receiving groove 14 is communicated with the first slide groove 13, and the gear rod 141 is meshed with the gear 71 fixedly connected to one end of the reciprocating screw 7. As the reciprocating screw 7 slides along the first slide groove 13, the gear rod 141 is meshed with the gear 71 fixedly connected to one end of the reciprocating screw 7. Under the action of 141, the gear 71 can be in a rotating state, so the gear 71 can drive the reciprocating screw 7 to rotate, and the reciprocating screw 7 is threadedly connected to the third limit slider 72, and the reciprocating screw 7 can drive the third limit slider 72 to slide left and right in the slide rod 4, wherein a limit connecting strip 721 is fixedly arranged on the periphery of the third limit slider 72, one end of the limit connecting strip 721 passes through the slide rod 4 and is connected to the drum 5, and a limit rolling groove 52 is provided in the drum 5, so that the drum 5 is in a rotating and swinging state, and a second slide groove 41 is provided on the periphery of the slide rod 4 for the limit connecting strip 721 to slide left and right, so as to ensure the state of left and right sliding of the drum 5.

[0049] Among them, through the setting that both sides of the limiting connecting strip 721 abut against the inner walls of the limiting rolling groove 52, when the limiting connecting strip 721 slides left and right in the second sliding groove 41, since both sides of the limiting connecting strip 721 abut against the inner walls of the limiting rolling groove 52, the limiting connecting strip 721 will drive the roller 5 to slide around the sliding rod 4 during the sliding process. This setting is convenient for the rotation of the roller 5 and also for the left and right sliding of the roller 5.

[0050] Among them, as long as the slide rod 4 slides in the first slide groove 13, the gear 71 will be in a rotating state by engaging with the gear rod 141, and then the third limit slider 72 can drive the limit connecting strip 721 to slide left and right, and the limit connecting strip 721 drives the roller 5 to slide left and right around the outer periphery of the slide rod 4.

[0051] Supplementary explanation: The reciprocating screw 7 is threadedly connected to the third limit slider 72, and the left and right movement of the third limit slider 72 can be realized, which is the prior art. Among them, the outer periphery of the reciprocating screw 7 is provided with a thread, and the thread is a thread for reciprocating movement. When the third limit slider 72 moves to the end of the reciprocating thread opened on the reciprocating screw 7, the third limit slider 72 can slide in the opposite direction as the reciprocating screw 7 continues to rotate. This process belongs to the working principle of the prior art of the reciprocating screw 7, and the specific structure of the reciprocating screw 7 is not specifically drawn in the accompanying drawings.

[0052] like Figure 8 and Fig. 9 As shown, the pulling mechanism includes a telescopic rod 53 and a second limit slider 621. A rotation groove 62 for the second limit slider 621 to slide is opened on the periphery of the limit rod 6. The rotation groove 62 is opened around the periphery of the limit rod 6. One end of the telescopic rod 53 is fixedly connected to the periphery of the drum 5, and the other end is rotatably connected to the second limit slider 621 through a lifting ear.

[0053] The rotary groove 62 is arranged around the outer periphery of the limit rod 6, and when the roller 5 is in the process of sliding left and right, the telescopic rod 53 can be driven to move, and the telescopic rod 53 drives the second limit slider 621 to slide in the rotary groove 62. Through the surrounding arrangement of the rotary groove 62, the distance between the second limit slider 621 and the roller 5 will change, thereby pulling the telescopic rod 53 and making the telescopic rod 53 in an inclined state. Since the telescopic rod 53 is rotatably connected to the second limit slider 621 through the lifting ear, when the telescopic rod 53 is extended and in an inclined state, the roller 5 can be pulled into a rotating state through one end of the telescopic rod 53. Since the roller 5 is in the process of sliding left and right, the pulling of the telescopic rod 53 on the roller 5 can make the roller 5 in a small range of rotational reciprocating swing, and then drive the detection mechanism arranged on the outer periphery of the roller 5 in the process of rotational reciprocating swing, so as to facilitate the detection of the gate plate in the convection channel 12 by the detection mechanism in an up and down sliding and left and right sliding manner, and the gate plate can be detected in all directions.

[0054] like Figure 6 As shown, the detection mechanism is provided with multiple groups, and the detection mechanism includes a connecting rod 51 and a detection probe 511 . One end of the connecting rod 51 is fixedly connected to the periphery of the drum 5 , and the other end is fixedly connected to the detection probe 511 .

[0055] By setting the detection probe 511, when the drum 5 is in a state of sliding left and right and swinging up and down, it can drive the connecting rod 51 to move accordingly, so that the detection probe 511 can be driven to slide left and right and swing up and down through the connecting rod 51, so as to facilitate the scanning and detection of the gate plate. Among them, the scanning and detection of the detection probe 511 will not be affected by the water flow, and ultrasonic detection probes, radiation detection probes, electromagnetic detection probes, etc. can be used. Radiation detection probes such as X-ray detection probes and gamma-ray detection probes, and electromagnetic detection probes such as eddy current detection probes all have the function of penetrating water flow for scanning and detection.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, a wire taking-up hole 111 is provided on the fixed column 11 at a position corresponding to the first slide groove 13, a pull rope for pulling the slide bar 4 to slide up and down is provided in the wire taking-up hole 111, a wire passing groove 16 for the pull rope to pass through and communicating with the first slide groove 13 is provided on the bottom surface of the wire taking-up hole 111, and a winding mechanism for winding up the pull rope is provided in the wire taking-up hole 111.

[0057] The winding mechanism includes a rotating rod 2, a one-way bearing 21 and a servo motor 22. The servo motor 22 is fixedly connected to the fixed column 11. The power output end of the servo motor 22 is fixedly connected to the rotating rod 2. The rotating rod 2 is rotatably set in the winding hole 111. The one-way bearing 21 is sleeved on the outer periphery of the rotating rod 2, and one end of the pull rope is fixedly connected to the outer periphery of the one-way bearing 21.

[0058] The one-way bearing 21 is provided to facilitate the winding of the pull rope, wherein the pull rope is not shown in the figure, and one end of the pull rope is fixedly connected to the one-way bearing 21, and the other end is fixedly wound on the slide bar 4. By starting the servo motor 22, the rotating rod 2 can be driven to rotate, and the rotating rod 2 drives the one-way bearing 21 to rotate in one direction. Due to the one-way rotation of the one-way bearing 21, the process of driving the one-way bearing 21 to rotate can wind up the pull rope, and the pull rope is wound around the outer periphery of the one-way bearing 21. When the servo motor 22 drives the rotating rod 2 to rotate in the other direction, the one-way bearing 21 is in the process of releasing the line, and the slide bar 4 can slide along the first slide groove 13 at this time. As long as the pull rope is in a moving state, the slide bar 4 can be in a moving state. Therefore, the servo motor 22 is started to make the slide bar 4 in a sliding state. The working process is: the servo motor 22 is started to drive the rotating rod 2 to rotate, and the rotating rod 2 drives the one-way bearing 21 to rotate, so that the one-way bearing 21 performs the process of winding and releasing the pull rope, so as to facilitate the sliding of the slide bar 4.

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a limiting mechanism for limiting the position of the pull rope is arranged in the wire collection hole 111, and the limiting mechanism includes a U-shaped support plate 3 and a limiting roller 31. The support plate 3 is fixedly arranged near the wire groove 16, and two limiting rollers 31 are arranged and are rotatably arranged in the support plate 3, and the pull rope passes between the limiting rollers 31.

[0060] A counterweight roller 42 which is rollingly connected to the pull rope is disposed on the periphery of the slide rod 4 , and a cleaning sliding member for cleaning the first slide groove 13 is disposed on the periphery of the bottom end of the counterweight roller 42 .

[0061] The setting of the limiting roller 31 and the counterweight roller 42 can limit the pull rope, so that the pull rope always slides along the first slide groove 13, and the pull rope will not be pulled to the outside to prevent the pull rope from derailing, thereby improving the use efficiency.

[0062] Among them, through the setting of the counterweight roller 42, the counterweight roller 42 slides in the first slide groove 13 under the action of gravity during the rope releasing process, and a cleaning sliding member is arranged on the outer periphery of the bottom end of the counterweight roller 42. The cleaning sliding member slides in the first slide groove 13 and can clean the inner wall of the first slide groove 13 to prevent it from affecting the sliding of the slide rod 4.

[0063] A flow groove 15 is provided on the dam body 1 at the bottom end of the first chute 13 , and the flow groove 15 is communicated with the first chute 13 , so that the inner wall of the first chute 13 can be cleaned by a cleaning sliding member and flow out from the flow groove 15 to avoid accumulation in the first chute 13 .

[0064] Supplementary explanation: Considering that the pull rope will be pulled into the outside world during the process of pulling the slide bar 4, this situation will not occur because the cross-section of the first slide groove 13 is a cross-shaped structure, and the position of the pull rope is in a blocked position. Figure 5 The state of the first slide groove 13 is shown in the figure, wherein the pull rope is in the dam body 1 and will not appear in the state of being straightened in the outside world, that is, the pull rope is prevented from escaping from the first slide groove 13 and will slide along the first slide groove 13.

[0065] A detection method for an engineering quality detection device comprises the following steps:

[0066] S1: Rope release: start the servo motor 22, so that the rotating rod 2 drives the one-way bearing 21 to rotate, and the pull rope is released. The slide bar 4 slides along the first slide groove 13 under the action of the counterweight roller 42;

[0067] S2: Sliding adjustment: When the slide bar 4 slides in the first slide groove 13, the gear 71 can be rotated under the action of the gear rod 141, and the gear 71 drives the reciprocating screw 7 to rotate, and then the roller 5 drives the detection probe 511 to slide left and right, so as to perform sliding scanning detection;

[0068] S3: Rotation and swing: When the drum 5 slides left and right, the second limit slider 621 can be driven to slide in the rotation groove 62 through the telescopic rod 53. During the sliding process, the telescopic rod 53 swings in an inclined state, thereby driving the drum 5 in a rotation and swing state, so that the drum 5 drives the detection probe 511 to rotate and swing, and performs a rotation and swing scanning detection;

[0069] S4: Reeling in the rope: The one-way bearing 21 rotates to reel the pull rope into the outer periphery of the one-way bearing 21 . This process can also make the slide bar 4 slide in the first slide groove 13 , and can also make the detection probe 511 slide left and right and rotate and swing, so as to perform a full-range scanning and detection on the gate plate in the flow channel opening 12 .

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
