Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to aqueduct butt joint gap detection equipment for water conservancy projects. Background Art

[0002] In large-scale water conservancy projects, aqueducts are overhead channels used to transport channel water across rivers, valleys, and depressions. They are primarily composed of precast stone, concrete, or reinforced concrete components. During installation, the precast components are aligned and connected, creating a butt joint at the interface between the two aqueducts. Waterstops are typically applied at these joints. Because the joints between adjacent aqueducts are their weakest point, they can change over time due to the impact of water flow or uneven foundation settlement. These changes can affect the stability of the aqueducts, leading to cracking and leakage. Therefore, these changes in the joints need to be tested to assess their robustness and long-term stability.

[0003] Patent announcement number CN216159791U discloses a device for detecting changes in the butt joint gap of aqueducts used in large-scale water conservancy projects. The device specifically includes: a connecting plate, a chute is provided in the middle of the connecting plate, a positioning shaft is movably connected to the inner cavity of the chute, a clamp is fixedly installed on the top of the positioning shaft, a mounting plate is provided on the bottom surface of the clamp, a bottom plate is fixedly installed on the bottom surface of the positioning shaft, and a positioning ring is fixedly installed on the top surface of the mounting plate. The detection device fixes two mounting plates to the bottom end of the aqueduct through four studs. When the butt joint changes, the distance between the two positioning shafts increases, thereby driving the clamp to move on the top surface of the connecting plate. By setting a scale on the top surface of the connecting plate, the distance between the two positioning shafts can be measured. There is no need to install the device multiple times during measurement, thereby ensuring the firmness of the device installation and improving the accuracy of the measurement.

[0004] However, the above-mentioned detection equipment has the following problems: although the detection equipment in the device can detect the gap of the aqueduct joint and alarm, it takes a certain amount of time for maintenance personnel to reach the aqueduct. During this period, due to the pressure of the water flow or other factors, the joint gap is likely to gradually increase, which will cause the aqueduct to leak and damage the structural stability. Summary of the Invention

[0005] The purpose of the present invention is to provide a device for detecting the joint gap of aqueducts used in water conservancy projects, so as to solve the problems raised in the above-mentioned background technology.

[0010] Long rods are symmetrically provided on both sides of the moving block. L-shaped rods are provided on the outer walls of the bottom sides of the long rods.

[0011] Further, a plurality of bumps contacting the top of the shielding plate are arranged at intervals on the bottom of the cross plate.

[0012] Further, multiple L-shaped rods are provided, and all the L-shaped rods on one long rod are connected to the corresponding cross plate.

[0013] Further, a sliding groove matching the shielding slide plate is opened on one side of the shielding plate close to the installation groove plate, and the cross section of the shielding plate is in a "匚" - shaped structure.

[0014] Further, an isolation mechanism is further included;

[0015] The isolation mechanism includes a hollow plate located on one side of the shielding plate away from the installation groove plate, and a disassembly rod slidably penetrating through the top end of the hollow plate and threadedly connected to the shielding plate. The end face of the hollow plate contacts the side wall of the shielding plate. The bottom surface of the upper bottom plate of the hollow plate is flush with the bottom surface of the shielding plate. An isolation cavity is formed between the hollow plate and the shielding plate.

[0016] Furthermore, at least two groups of the disassembly rods are provided.

[0017] Furthermore, outer walls on both sides of the hollow plate are provided with inclined surfaces, and the inclined surfaces of the hollow plate are provided with a plurality of diversion grooves spaced apart from top to bottom.

[0018] Furthermore, two limit plates are respectively arranged on the positioning shaft at intervals, and the two limit plates on the positioning shaft are respectively located on the top side and the bottom side of the mounting slot plate.

[0019] The present invention has the following beneficial effects:

[0020] 1. The aqueduct joint gap detection device for water conservancy projects of the present invention is installed on the top of the side wall of the adjacent aqueduct, and the shielding plate is corresponding to the inner wall of the aqueduct; when the joint gap changes, the distance between the two positioning axes will increase, and the telescopic scale measuring piece will measure the moved distance. When the change in the joint gap is about to reach the maximum value, the telescopic scale measuring piece will issue an alarm; through the cooperation of the electric telescopic rod, the shielding plate, the shielding slide plate, the slide chute, and the slide column, when the staff receives the alarm, they immediately start the controller through the external Internet of Things control system, and start the electric telescopic rod through the controller. The telescopic end of the electric telescopic rod further pushes the shielding plate to move downward along the inner wall of the aqueduct. The movement of the shielding plate will drive the shielding slide plate to move downward along the slide column, thereby blocking the joint gap of the aqueduct and preventing the joint gap from gradually becoming larger due to the pressure of water flow during the time when the maintenance personnel arrive at the aqueduct, thereby avoiding water leakage and damage to the structural stability.

[0021] 2. The aqueduct joint gap detection equipment for water conservancy projects of the present invention cooperates with the square trough frame, elastic telescopic rod, moving block, hinged plate, first arc block, telescopic plate, fixed plate, second arc block, long rod, L-shaped rod and cross plate. When the shielding plate moves downward, the telescopic plate will be extended and retracted with the cooperation of the first arc block, telescopic plate and second arc block, and then the moving block will slide up and down in the square trough frame, and the cross plate will be driven by the long rod and L-shaped rod to knock on the shielding plate, so that the shielding plate will shake when it descends. The shaking of the shielding plate can shake off the mud and other debris adhering to the inner wall of the aqueduct, thereby avoiding the debris adhering to the inner wall of the aqueduct from obstructing the shielding plate, and thus avoiding affecting the shielding effect of the shielding plate on the joint.

[0022] 3. The aqueduct joint gap detection equipment for water conservancy projects of the present invention, through the cooperation of the hollow plate, the disassembly rod and the isolation cavity, when the hollow plate is moved to the inside of the aqueduct under the drive of the shielding plate, an isolation cavity will be formed around the joint, which can isolate the joint blocked by the shielding plate and ensure that there will be no large amount of water flowing in the isolation cavity, thereby facilitating the maintenance personnel to perform water-stopping treatment on the cracks at the joint; at the same time, through the cooperation of the diversion trough and the shielding plate, the water flow will flow along the inclined surface when passing through the inclined surfaces on both sides of the hollow plate, thereby reducing the impact force of the water flow on the hollow plate, making it more convenient for the staff to perform water-stopping treatment on the cracks.

[0032] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0033] As Figures 1 to 4 shown, in an embodiment of the present invention, a detection device for the docking gap of a flume used in a water conservancy project is provided, including an installation groove plate 1. A chute is provided in the installation groove plate 1. Two positioning shafts 2 are slidably connected in the chute of the installation groove plate 1. Installation plates 3 are provided at the bottoms of the two positioning shafts 2. Two threaded holes are provided in the installation plates 3. The two installation plates 3 are respectively fixed to the top of the side wall of the adjacent flume through stud bolts. A telescopic scale measuring member 4 is connected between the two positioning shafts 2 below the installation groove plate 1; the telescopic scale measuring member 4 adopts the components in the existing literature CN216159791U, and specifically includes a fixed sleeve, a telescopic shaft, a battery, a signal transmitter, and a power connection terminal. A positioning groove is provided on the telescopic shaft. The setting methods and connection relationships of the fixed sleeve, the telescopic shaft, the battery, the signal transmitter, and the power connection terminal are the same as those in the prior art and will not be described in detail here. Two limiting plates 7 are respectively arranged at intervals on the positioning shaft 2, and the two limiting plates 7 on the positioning shaft 2 are respectively located on the top side and the bottom side of the installation groove plate 1. The limiting plate 7 is used to position the distance between the installation groove plate 1 and the positioning shaft 2.

[0034] In order to block the docking seam on the inner side wall of the flume, a shielding mechanism 5 is provided on one side of the top of the installation groove plate 1; specifically, the shielding mechanism 5 includes a support block 51 provided on one side of the top of the installation groove plate 1. The support block 51 is arranged vertically and is located on one side of the chute on the installation groove plate 1 and does not interfere with the movement of the positioning shaft 2; an electric telescopic rod 52 provided on the inner wall of the top of the support block 51. The electric telescopic rod 52 is vertically fixed to the inner wall of the top of the support block 51 through screws, and the telescopic end of the electric telescopic rod 52 is arranged downward; a shielding plate 53 provided on the telescopic end of the electric telescopic rod 52 and located on one side of the installation groove plate 1, and shielding sliding plates 54 slidably arranged on both sides of the shielding plate 53; by providing a chute on the side of the shielding plate 53 close to the installation groove plate 1 that matches the shielding sliding plate 54, the sliding fit between the shielding sliding plate 54 and the shielding plate 53 is realized, and the cross-section of the shielding plate 53 is in a "匚" - shaped structure; vertical chutes 55 are respectively provided on the sides of the two shielding sliding plates 54 close to the positioning shaft 2. A sliding column 56 slidably matched with the vertical chute 55 is provided on the outer wall of the positioning shaft 2. The end of the sliding column 56 far from the positioning shaft 2 extends into the vertical chute 55, and vertical limiting grooves are respectively provided on the inner walls of both sides of the vertical chute 55. Limiting blocks matched with the vertical limiting grooves are symmetrically arranged on the outer wall of the sliding column 56 located in the vertical chute 55. With such a setting, the sliding column 56 can be prevented from slipping out of the vertical chute 55.

[0035] A controller and power supply can be installed on the lower beam of the aqueduct. The power supply can be an existing solar panel and battery, and can provide power to the controller and the electric telescopic rod 52. When the electric telescopic rod 52 is activated, its telescopic end pushes the shielding plate 53 downward along the inner wall of the aqueduct. The movement of the shielding plate 53 drives the shielding slide 54 downward along the sliding column 56, thereby shielding the aqueduct joint. This prevents the joint from gradually widening due to water pressure during the time when maintenance personnel are in the aqueduct, thereby preventing water leakage and damage to the structural stability.

[0036] like Figure 4 and Figure 5 As shown, the shielding mechanism 5 also includes a square groove frame 57 provided on the top of one side of the shielding plate 53 close to the mounting groove plate 1, and the square groove frame 57 is vertically fixed to the top side wall of the shielding plate 53; an elastic telescopic rod 58 is vertically provided on the top inner wall of the square groove frame 57, and the elastic telescopic rod 58 includes a fixed tube fixed to the top inner wall of the square groove frame 57, an inner rod slidably provided in the fixed tube, and a spring 1 (not shown) connected between the top of the inner rod and the top inner wall of the fixed tube, and the inner rod serves as the telescopic end of the elastic telescopic rod 58; A moving block 59 is provided at the bottom of the telescopic end of the elastic telescopic rod 58 and is slidably matched with the interior of the square groove frame 57. The length of the moving block 59 matches the internal width of the square groove frame 57; a hinged plate 510 is hinged on the side of the moving block 59 away from the square groove frame 57; a first arc block 511 is hinged on the end of the hinged plate 510 away from the square groove frame 57; a telescopic plate 512 is provided on the inner wall of the square groove frame 57 and located below the moving block 59. The telescopic plate 512 includes a fixed square tube fixed transversely to the inner wall of the square groove frame 57. , a movable plate that slides with the fixed square tube, a spring 2 (not shown) is connected between the end of the movable plate and the inner wall of the fixed square tube, the end of the movable plate away from the spring 2 extends out of the fixed square tube, and the movable plate serves as the telescopic end of the telescopic plate 512; a fixed plate 513 is arranged on the side of the support block 51 close to the shielding plate 53, and a plurality of second arc blocks 514 are arranged from top to bottom on the side of the fixed plate 513 close to the shielding plate 53, the telescopic end of the telescopic plate 512 is connected to the side wall of the first arc block 511, and the second The arc block 514 is located on the moving path of the first arc block 511, with the arc surface of the first arc block 511 facing the arc surface of the second arc block 514. The thickness of the moving block 59 is greater than the depth of the square groove in the square groove frame 57. Long rods 515 are symmetrically provided on both sides of the moving block 59. The long rods 515 are located outside the square groove frame 57. L-shaped rods 516 are provided on the bottom outer wall of the long rods 515. A horizontal plate 517 is provided on the end of the L-shaped rod 516 away from the long rod 515. The bottom of the horizontal plate 517 contacts the top of the shielding plate 53. In addition, a number of protrusions are provided at intervals on the bottom of the horizontal plate 517 to contact the top of the shielding plate 53.

[0037] In this embodiment, a plurality of L-shaped rods 516 are provided, and all L-shaped rods 516 on one long rod 515 are connected to corresponding transverse plates 517 .

[0038] When the shielding plate 53 moves downward, the shielding plate 53 will drive the square groove frame 57 to move, and the square groove frame 57 will drive the telescopic plate 512 to move, and the telescopic plate 512 will drive the first arc block 511 to move. When the first arc block 511 moves, its arc surface will contact the arc surface of the second arc block 514, so that the first arc block 511 moves toward the direction of the square groove frame 57 and compresses the telescopic end of the telescopic plate 512. At the same time, the first arc block 511 will also push the moving block 59 to move upward along the inner wall of the square groove frame 57 through the hinged plate 510. The upward movement of the moving block 59 will squeeze the elastic telescopic rod 58. At the same time, the upward movement of the moving block 59 will drive the long rod 515 to move upward, and the upward movement of the long rod 515 will drive the L-shaped rod 51 When the first arc block 511 is moved upward, the L-shaped rod 516 moves upward and drives the horizontal plate 517 away from the shielding plate 53; when the arc surface of the first arc block 511 does not conflict with the arc surface of the second arc block 514, the elastic telescopic rod 58 and the telescopic plate 512 drive the first arc block 511, the moving block 59, the long rod 515, the L-shaped rod 516 and the horizontal plate 517 to reset by their own elastic force, and so on, the horizontal plate 517 knocks against the shielding plate 53, so that the shielding plate 53 shakes when it descends. The shaking of the shielding plate 53 can shake off the mud and sand and other debris adhering to the inner wall of the aqueduct, thereby preventing the debris adhering to the inner wall of the aqueduct from obstructing the shielding plate 53, and further avoiding affecting the shielding effect of the shielding plate 53 on the seam.

[0039] like Figure 6 and Figure 7As shown, another embodiment of the present invention provides a water conservancy project aqueduct joint gap detection device, which also includes an isolation mechanism 6; the isolation mechanism 6 includes a hollow plate 61 located on the side of the baffle plate 53 away from the installation groove plate 1, the end face of the hollow plate 61 contacts the side wall of the baffle plate 53, the interior of the hollow plate 61 is hollow, and the side of the hollow plate 61 close to the baffle plate 53 has an opening, and the top also has an opening; and a disassembly mechanism 61 that is slidably provided on the top of the hollow plate 61 and is threadedly connected to the baffle plate 53 Rod 62, the side wall of the baffle 53 is provided with a threaded hole corresponding to and matching the disassembly rod 62, and the end of the disassembly rod 62 is provided with an external thread that matches the threaded hole; the bottom surface of the upper base of the hollow plate 61 is flush with the bottom surface of the baffle 53, and an isolation chamber 63 is formed between the hollow plate 61 and the baffle 53; the isolation chamber 63 can isolate the joint blocked by the baffle 53 and ensure that no large amount of water flows in the isolation chamber 63, thereby facilitating maintenance personnel to perform water-stopping treatment on the cracks at the joint. At least two groups of disassembly rods 62 are provided to ensure the stability of the connection between the hollow plate 61 and the baffle 53. The outer walls on both sides of the hollow plate 61 are provided with inclined surfaces, and the inclined surfaces of the hollow plate 61 are spaced apart from each other by a number of diversion grooves 64 from top to bottom. When the hollow plate 61 is moved to the inside of the aqueduct under the drive of the shielding plate 53, an isolation cavity 63 is formed around the joint. When the maintenance personnel are ready to perform water-stopping treatment on the cracks in the joint, they rotate the disassembly rod 62 to make the hollow plate 61 no longer connected to the shielding plate 53, and then drive the telescopic end of the electric telescopic rod 52 to retract through the external controller. The retraction of the telescopic end of the electric telescopic rod 52 will drive the shielding plate 53 to move upward and reset, and finally the shielding plate 53 no longer blocks the joint. When the shielding plate 53 is reset, the hollow plate 61 is immediately brought into contact with the inner wall of the aqueduct, thereby ensuring that there will be no large amount of water flowing between the hollow plate 61 and the inner wall of the aqueduct, thereby facilitating the maintenance personnel to perform water-stopping treatment on the cracks in the joint; at the same time, through the cooperation of the diverter groove 64 and the shielding plate 53, the water will flow along the inclined surfaces on both sides of the hollow plate 61 when passing through the inclined surfaces, thereby reducing the impact force of the water flow on the hollow plate 61, making it easier for the staff to perform water-stopping treatment on the cracks.

[0040] like Figure 8 As shown, the water conservancy project aqueduct joint gap detection device of the present invention is suitable for detecting and treating the joints of the two side walls of the aqueduct. The use process is as follows:

[0041] (1) During installation, the mounting plate 3 at the bottom of one positioning shaft 2 is fixed to the top of the side wall of the aqueduct by means of bolts, and the mounting plate 3 at the bottom of the other positioning shaft 2 is fixed to the top of the side wall of the adjacent aqueduct by means of bolts, and the shielding plate 53 is made to correspond to the inner side wall of the aqueduct.

[0042] (2) When the joint changes, the distance between the two positioning shafts 2 will increase, so that the two shielding slides 54 can be driven to slide in opposite directions along the shielding plate 53 through the sliding column 56. The telescopic scale measuring piece 4 will measure the distance moved by the two positioning shafts 2. When the change in the joint is about to reach the maximum value, the telescopic scale measuring piece 4 will issue an alarm. When the staff receives the alarm, they will immediately start the controller through the external Internet of Things control system and start the electric telescopic rod 52 through the controller. When the electric telescopic rod 52 is started, its telescopic end will push the shielding plate 53 to move downward along the inner wall of the aqueduct. The movement of the shielding plate 53 will drive the shielding slide 54 to move downward along the sliding column 56, thereby shielding the joint of the aqueduct and preventing the joint from gradually becoming larger due to the pressure of water flow during the time when the maintenance personnel arrive at the aqueduct, thereby avoiding water leakage and damage to the structural stability. The maintenance personnel can formulate a water-stopping plan based on the scale on the telescopic scale measuring piece 4.

[0043] (3) When the shielding plate 53 moves downward, the shielding plate 53 will drive the square groove frame 57, the elastic telescopic rod 58, the moving block 59, the hinged plate 510, the first arc block 511, and the telescopic plate 512 to move, and under the cooperation of the first arc block 511 and the second arc block 514, the long rod 515 will eventually drive the horizontal plate 517 away from the shielding plate 53 through the L-shaped rod 516. When the arc surface of the first arc block 511 does not conflict with the arc surface of the second arc block 514, the elastic telescopic rod 58, The telescopic plate 512 will drive the first arc block 511, the moving block 59, the long rod 515, the L-shaped rod 516 and the horizontal plate 517 to reset, and so on, so that the horizontal plate 517 knocks on the shielding plate 53, so that the shielding plate 53 will shake when moving downward along the aqueduct, thereby shaking off the mud and other debris adhering to the inner wall of the aqueduct, and preventing the debris adhering to the inner wall of the aqueduct from obstructing the shielding plate 53, thereby avoiding affecting the shielding effect of the shielding plate 53 on the joint.

[0044] (4) The shielding plate 53 moves and drives the hollow plate 61 to move downward. When the maintenance personnel are ready to perform water-stopping treatment on the cracks of the joint, they rotate the disassembly rod 62 and make the hollow plate 61 disconnected from the shielding plate 53. Then, the telescopic end of the electric telescopic rod 52 is driven to retract by the external controller. The retraction of the telescopic end of the electric telescopic rod 52 will drive the shielding plate 53 to move upward and reset. At the same time as the shielding plate 53 is reset, the hollow plate 61 is immediately brought into contact with the inner wall of the aqueduct, thereby ensuring that there will be no large amount of water flowing between the hollow plate 61 and the inner wall of the aqueduct, thereby facilitating the maintenance personnel to perform water-stopping treatment on the cracks at the joint.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
