[0001] This invention relates to the field of marine equipment technology, specifically to a rigid sweeping bed frame capable of predicting the size of reefs and its usage method. Background Technology

[0002] Underwater rigid sweeping beds are the main engineering quality testing method in the self-inspection and acceptance stages and dredging acceptance stages of waterway improvement and blasting projects, and are widely used in port and various waterway improvement projects.

[0003] During bed sweeping, reefs smaller than the design depth will obstruct the sweeping rod and be detected. However, existing bed sweeping frames cannot accurately predict the height and extent of reefs exceeding the design depth. Summary of the Invention

[0004] The purpose of this invention is to provide a rigid sweeping bed frame that can predict the size of reefs and its usage method, so as to solve the problem that existing sweeping bed frames cannot accurately predict the height and range of reefs that exceed the design depth.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rigid sweeping bed frame capable of predicting the size of reefs, comprising a rotating frame, a vertical rod, a fixing device, and a measuring device.

[0006] The rotating frame includes a rotating plate and a rotating shaft. There are two or more sets of rotating plates, and adjacent sets of rotating plates are connected by a rotating shaft. The rotating shaft divides the rotating plate into an upper part and a lower part. The length of the lower rotating plate is n times that of the upper plate. When encountering obstacles or rocks during the sweeping process, the rotating plate rotates along the rotating shaft and avoids the obstacles or rocks.

[0007] One end of the vertical rod is fixed to the rotating shaft, and the other end is fixed to the motorboat through the fixing device;

[0008] One end of the fixing device is detachably connected to the vertical rod, and the other end is fixed to the motorboat; the measuring device is also fixed on the fixing device.

[0009] The measuring device has two or more sets, corresponding to the number of rotating plates; the measuring device includes a wire rope, a spring and a scale, one end of the wire rope is connected to the upper part of the rotating plate and the other end is connected to the spring, the end of the spring away from the wire rope is connected to the fixing device, and the scale is attached to the spring.

[0010] Preferably, there are four sets of rotating plates and four sets of measuring devices, and two sets of vertical rods and two sets of fixing devices, with the vertical rods respectively located on the port and starboard sides of the motorboat.

[0011] Preferably, the rotating plate is made of seamless steel pipes welded into a grid shape, which provides a stable structure and reduces resistance.

[0012] Preferably, the rotating shaft includes a shaft, a clamp, and a first ear seat. The first ear seat is welded onto the clamp, the clamp is tightened to the shaft with bolts, and the first ear seat is fixedly connected to the vertical rod by bolts.

[0013] Preferably, the device further includes a lifting mechanism connected to the upper part of the rotating plate. The lifting mechanism adjusts the raising and lowering of the rotating frame. Specifically, the rotating frame is lowered into the water for measurement within the measurement area using the lifting mechanism, and retracted when the measurement area is removed.

[0014] Preferably, the lifting device includes a hydraulic winch, a lifting wire rope, a fixed crossbar, and a pulley. The hydraulic winch and the fixed crossbar are respectively fixed on the motorboat. The pulley is fixed on the fixed crossbar. One end of the lifting wire rope is connected to the upper part of the rotating plate, and the other end passes through the pulley on the fixed crossbar and is finally connected to the hydraulic winch.

[0015] Preferably, there are two lifting wire ropes, and the two lifting wire ropes are respectively connected to two different sets of rotating plates.

[0016] Preferably, one end of the fixing device is rotatably connected to the vertical rod and fixed with bolts. When the lifting device raises the rotating frame, the vertical rod rotates around the fixing device. When the rotating frame is raised to the water surface, the vertical rod is then fixed to the fixing device with bolts. During measurement, the rotating frame is placed in the water by the lifting device, the vertical rod rotates around the fixing device to a vertical position, and then the vertical rod is fixed to the fixing device with bolts.

[0017] Another technical solution of this application: The method of using the above-mentioned rigid sweeping bed frame includes the following steps:

[0018] Calculate the height of the obstacle: Record the initial length l0 of the spring before the rotating plate rotates, and record the spring length l at the instant the rotating plate completely passes the obstacle. Then the extension of the spring 520 is Δl = l - l0; the height of the obstacle is h ≈ nΔl.

[0019] To measure the width of an obstacle: determine which rotating plate is rotating or which rotating plates are rotating simultaneously, and add up the widths of the rotating plates that are rotating simultaneously. This sums up the width of the reef.

[0020] Preferably, n is an integer for ease of calculation.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This application sets up multiple sets of rotating plates, each set of rotating plates is equipped with a measuring device with a spring. The height of the reef can be calculated by recording the change in the extension of the spring of the measuring device during the rotation of the rotating plate when it encounters a reef; the width of the reef can be calculated by recording the width of the rotating plates that rotate simultaneously. At the same time, the spring can automatically reset the movable plate of the sweeping frame to a vertical state, without affecting subsequent measurements. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 3 As shown, the rigid sweeping frame in this embodiment that can predict the size of the reef includes: a rotating frame 100, a vertical rod 200, a lifting device 300, a fixing device 400, and a measuring device 500.

[0034] The rotating frame 100 includes a rotating plate 110 and a rotating shaft 120. The rotating frame 100 is placed in water for sweeping the bed. When encountering obstacles or rocks during the sweeping process, the rotating plate 110 of the rotating frame 100 can rotate along the rotating shaft 120 to avoid the obstacles or rocks.

[0035] The lower end of the vertical rod 200 is fixed to the rotation shaft 120 of the rotating frame 100. The upper middle part of the vertical rod 200 is detachably connected to the fixing device 400 by bolts. The water depth of the vertical rod 200 can be adjusted by adjusting the connection position between the vertical rod 200 and the fixing device 400, thereby adjusting the rotating frame 100 to the designed water depth.

[0036] The lifting device 300 is installed on the motorboat. The lifting wire rope 320 of the lifting device 300 is connected to the rotating frame 100. The rotating frame 100 can be adjusted to be in a vertical or horizontal state by adjusting the extension and retraction of the lifting wire rope 320.

[0037] One end of the fixing device 400 is detachably connected to the vertical rod 200, and the other end is fixed to the motorboat. The fixing device 400 also fixes the measuring device 500.

[0038] The measuring device 500 is fixed to the fixing device 400 and is used to measure the rotation of the rotating plate 110, thereby estimating the height of the obstacle reef, and automatically resetting the rotating plate 110 to a vertical state after the bottom edge of the rotating plate 110 passes the obstacle reef.

[0039] Specifically, in combination Figure 1The rotating shaft 120 of the rotating frame 100 is arranged parallel to the width direction of the motorboat. The rotating plate 110 consists of a first rotating plate 111, a second rotating plate 112, a third rotating plate 113, and a fourth rotating plate 114. The first rotating plate 111 is connected to the third rotating plate 113 via the rotating shaft 120. The other end of the third rotating plate 113 is connected to the fourth rotating plate 114 via the rotating shaft 120. The other end of the fourth rotating plate 114 is connected to the second rotating plate 112 via the rotating shaft 120. Of course, in other embodiments, different numbers of rotating plates can be provided. Specifically, the first rotating plate 111, the second rotating plate 112, the third rotating plate 113, and the fourth rotating plate 114 are welded with Ф60 seamless steel pipes around their perimeter and reinforced with Ф38 seamless steel pipes in the middle. The rotating shaft 120 divides the rotating plate into an upper rotating part and a lower rotating part, and the length of the lower rotating plate is n times that of the upper rotating plate. The upper parts of the first rotating plate 111, the second rotating plate 112, the third rotating plate 113, and the fourth rotating plate 114 are each welded with a third ear seat 140, which is connected to the steel wire rope 510 of the measuring device 500. The upper parts of the third rotating plate 113 and the fourth rotating plate 114 are also welded with a second ear seat 130, which is connected to the lifting steel wire rope 320 of the lifting device 300. Specifically, the moving rotating shaft 120 consists of a rotating shaft 121, a clamp 122, and a first ear seat 123. Two sets of clamps 122 are provided, and the first ear seat 123 is welded to the clamps 122. The clamps 122 are tightened to the rotating shaft 121 with bolts, and the first ear seat 123 is connected to the ear plate of the vertical rod 200.

[0040] Specifically, there are two vertical rods 200, located on the port and starboard sides of the motorboat. Each vertical rod 200 consists of two uprights and a cross brace welded together, with a lug plate welded to the lower end of each upright. Figure 4 The ear plate is fixed to the first ear seat 123 of the rotating frame 100 by means of ear plate. Specifically, the ear plate and the first ear seat 123 are fixed by bolts.

[0041] Specifically, in combination Figure 1The lifting device 300 includes a hydraulic winch 310, lifting wire ropes 320, a fixed crossbar 330, and pulleys 340. Two lifting wire ropes 320 are provided; one end of one is connected to the second lug 130 of the third rotating plate 113, and one end of the other is connected to the second lug 130 of the fourth rotating plate 114. The other ends of the two lifting wire ropes 320 pass through the pulleys 340 at both ends of the fixed crossbar 330, and finally connect to the drum of the hydraulic winch 310. The fixed crossbar 330 is installed on the deck of the motorboat and is arranged along the width direction of the motorboat. Two sets of pulleys 340 are provided; one set is installed at both ends of the fixed crossbar 330, and the other set is installed on the motorboat's guide rail. The two sets of pulleys 340 are set up to change the direction of the force of the two lifting wire ropes 320. That is, by the rolling of the drum connected to the hydraulic winch 310, the lifting wire ropes 320 can be extended and retracted, thereby driving the third rotating plate 113 and the fourth rotating plate 114 to rotate along the rotating shaft 120, so as to realize the raising or lowering of the rotating frame 100.

[0042] Specifically, in combination Figure 1 The fixing device 400 includes a fixed base 410 and a movable lug 420. Two sets of fixing devices 400 are provided, with the fixed bases 410 of both sets installed on the deck of the motorboat, located on the port and starboard sides respectively. The sweeping frame is raised or lowered by the lifting device 300. During this process, the vertical rod 200 rotates around the fixed base 410. The movable lug 420 adjusts the height of the vertical rod 200 according to the required sweeping depth. After the required depth is met, the vertical rod 200 is locked with bolts.

[0043] Specifically, in combination Figure 3 The measuring device 500 includes a wire rope 510, a spring 520, and a scale 530. In this embodiment, four sets of measuring devices 500 are provided, each set matching the first to fourth rotating plates 110 respectively. In other embodiments, the number of rotating plates 110 is adjusted, and the number of measuring devices 500 is also adjusted accordingly. Specifically, one end of the wire rope 510 is connected to the third lug 140 of the rotating plate 110, and the other end is connected to the spring 520. The end of the spring 520 away from the wire rope 510 is connected to the movable lug 420 of the fixing device 400, and the scale 530 is attached to the spring 520. The end of the wire rope 510 connected to the spring 520 is tied with a cable tie, and the wire rope 510 can be lengthened or shortened according to the depth of the sweeping bed. When the boat encounters an obstacle during the sweeping process, the rotating plate 110 will rotate, and the spring 520 will be stretched due to the force. After the bottom edge of the rotating plate 110 passes the obstacle reef, the spring 520 will cause the rotating plate 110 to automatically return to its vertical position.

[0044] The method of using the rigid sweeping bed frame in this embodiment is as follows:

[0045] The width and height of the rotating plate 110 are determined according to the needs of the sweeping machine. In this embodiment, the rotating plate 110 consists of a first rotating plate 111, a second rotating plate 112, a third rotating plate 113, and a fourth rotating plate 114. In other embodiments, different numbers of rotating plates can also be provided. The rotating plate 110 is divided into an upper part and a lower part on the rotating shaft 120, with the upper part being smaller and the lower part being larger. The length of the lower part is n times the length of the upper part, where n is an integer for easy calculation.

[0046] When the motorboat sails to the waters where the bed sweeping is required, after measuring the depth of the bed sweeping frame, the vertical rod 200 is locked with the bolts of the movable lug 420 of the fixing device 400, and then the bed sweeping frame is lowered to the vertical position using the lifting device 300.

[0047] During the sweeping process, the vertical rod 200 of the sweeping frame should be kept as vertical as possible. Before the sweeping begins, check that the initial state of the rotating plate 110 of the rotating frame 100 is vertical. After the rotating plate 110 of the rotating frame 100 passes around the obstacles and rocks during the sweeping process, it is necessary to ensure that the rotating plate 110 of the rotating frame 100 is reset to ensure the accuracy of the measurement data.

[0048] During the sweeping process, when the rotating plate 110 of the rotating frame 100 encounters an obstacle rock, it will rotate around the rotating shaft 121 of the rotating shaft 120. During the rotation of the rotating plate 110, the spring 520 of the measuring device 500 connected to the third ear seat 140 of the rotating plate 110 is stretched due to the force. When the rotating plate 110 of the rotating frame 100 completely passes through the rock, the elongation Δl of the spring 520 is calculated.

[0049] Combination Figure 2 During the sweeping process, when the rotating frame 100 encounters an obstacle or reef, the rotating plate 110 rotates around the pivot 121 of the rotating shaft 120. The bottom edge of the rotating plate 110 passes through the top of the reef, creating a height difference h between its initial position and the position. Additionally, the upper part of the rotating plate 110 also rotates. The spring 520 of the measuring device 500, connected to the third lug 140 of the rotating plate 110, is stretched due to the force. The initial reading l0 of the spring 520 is recorded before the rotating plate 110 rotates, and the reading l is recorded the instant the rotating plate 110 has completely passed through the obstacle. Therefore, the elongation of the spring 520 is Δl = l - l0. Based on actual analysis using diagrams, within the current water depth range of our construction, the influence of the elevation depth is negligible. Therefore, the relationship between h and Δl is: h ≈ ​​nΔl, with a deviation within +15mm. Thus, h is the height of the reef exceeding the elevation depth range.

[0050] During the bed sweeping process, carefully observe the changes in the spring 520 of each measuring device 500, determine the rotation of the rotating plate 110, and record the initial reading l0 of the spring 520 before the rotating plate 110 rotates and the reading l of the spring 520 at the instant it passes through. Then, the height of the reef exceeding the depth is n times the elongation Δl of the spring 520. Based on the rotation of the rotating plate 110, determine which rotating plate is rotating or which rotating plates are rotating simultaneously. Combine them and add up the widths of the rotating plates that are rotating simultaneously, which is the width of the reef.

[0051] In summary, this application uses multiple sets of rotating plates 110, each equipped with a measuring device 500 with a spring 520. The height of the reef can be calculated by recording the change in the extension of the spring 520 of the measuring device 500 during the rotation of the rotating plate 110 when it encounters a reef; the width of the reef can be calculated by recording the width of the simultaneously rotating plates 110. Simultaneously, the spring 520 automatically returns the movable plate 110 of the sweeping frame to a vertical position, without affecting subsequent measurements.
