Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of riprap construction for offshore wind power projects, in particular to a real-time depth measuring device for riprap with conduit. Background Art
[0002] With the booming development of offshore wind power projects in my country, the scouring problem faced by wind turbines in seawater has gradually become prominent. At present, the solution to scouring is mainly based on stone dumping. Before construction, multi-beam equipment is used to detect the underwater scouring of wind turbines, measure the location of stone dumping, and the approximate volume. For more accurate stone dumping, a longer retractable catheter is usually inserted into the bottom of the water to transport the stone to the scouring location.
[0003] It is difficult to control the length of the conduit when throwing stones, which can easily cause the conduit mouth to be too far or too close to the target position. When the conduit is too far, the stones will be washed away by the water flow or the position will be offset, resulting in too little or too much stone throwing at the target position. Too little stone throwing will fail to pass the acceptance, and too much stone throwing will not only increase costs, but also make the seabed uneven and cause secondary scouring. When the conduit is too close, it may touch the bottom and damage the equipment, posing a safety hazard to equipment and personnel. Utility Model Content
[0004] The purpose of the utility model is to provide a real-time depth measurement device for riprap with a conduit, which can monitor the distance from the conduit port to the seabed in real time and accurately through a depth sounder, thereby avoiding the problems and hidden dangers caused by the conduit port being too far or too close to the seabed target position during riprap operation in the prior art. In order to achieve the above technical features, the purpose of the utility model is achieved as follows:
[0005] A real-time depth measuring device for riprap with a conduit, comprising a ball joint and a depth sounder;
[0006] The ball seat of the ball joint is installed on the outside of the conduit and close to the conduit opening, and the end of the hinge rod of the ball joint is hinged to the top of the box body with an opening at the bottom;
[0007] The depth sounder is installed in the inner cavity of the shell, and the probe of the depth sounder monitors the distance between the conduit port and the seabed target position through the opening.
[0008] The depth sounder is a single beam depth sounder.
[0009] The box body is formed by two symmetrically distributed shells connected in a detachable manner.
[0010] The shell comprises a body, a lug plate is provided on the side of the body, and the two shells are connected by first fastening bolts on the lug plate.
[0011] The utility model has the following beneficial effects: the ball seat of the ball joint is installed on the outside of the conduit and close to the conduit opening, the hinge rod end of the ball joint is hinged to the top of the box body with an opening at the bottom, and under the action of gravity, the depth sounder in the box body always maintains a state close to vertical to the seabed, so as to measure the accurate distance from the conduit opening to the seabed, and the depth sounder transmits the signal to the conduit operating platform, and the operator can make real-time adjustments to the conduit; on the one hand, accurate adjustment of the distance between the conduit and the seabed can greatly reduce the stones washed away by the water flow, thereby reducing the loss of stones and saving costs; on the other hand, real-time adjustment of the conduit height greatly reduces the risk of the conduit being too close to the seabed or even touching the seabed; the qualified rate of construction is increased, the construction period is shortened, and the construction cost is reduced.

[0018] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.
[0019] See attached Figure 1-4 In order to realize the above technical features, the purpose of the utility model is achieved as follows:
[0020] A real-time depth measurement device for riprap of a conduit comprises a ball joint 1 and a depth sounder 2; the ball seat 1a of the ball joint 1 is installed on the outside of the conduit and close to the conduit opening, the end of the hinge rod 1b of the ball joint 1 is hinged to the top of a box body 3 with an opening 3a at the bottom; the depth sounder 2 is installed in the inner cavity of the shell 3, and the probe of the depth sounder 2 monitors the distance between the conduit opening and the target position on the seabed through the opening 3a.
[0021] In the prior art, before construction, a multi-beam device is first used to detect the underwater scouring of the wind turbine, and to measure the location and approximate volume of the stone throwing. Then, a retractable catheter is inserted into the bottom of the water to transport the stone to the scouring location. It is difficult to control the depth of the catheter when throwing stones through the catheter, and it is easy for the catheter mouth to be too far or too close to the target location. When the catheter is too far away, the stone will be washed away by the water flow or the position will be shifted, resulting in too little or too much stone throwing at the target location. Too little stone throwing cannot pass the acceptance, and too much stone throwing will not only increase the cost, but also make the seabed terrain uneven, causing secondary scouring. When the catheter is too close, it may touch the bottom and damage the equipment, posing a safety hazard to equipment and personnel.
[0022] The utility model includes a ball joint 1, a depth sounder 2 and a box body 3; the ball seat 1a of the ball joint 1 is installed on the outside of the catheter and close to the catheter mouth, and the end of the hinge rod 1b of the ball joint 1 is hinged to the top of the box body 3 with an opening 3a at the bottom; under the action of gravity, the depth sounder 2 installed in the inner cavity of the box body 3 always maintains a state close to the vertical seabed, thereby ensuring that the measured data is the accurate distance from the catheter mouth to the seabed. When working, the probe of the depth sounder 2 monitors the distance between the catheter mouth and the seabed target position in real time through the opening 3a, and transmits the signal to the catheter control platform, so that the operator can adjust the catheter in real time, thereby avoiding the problems and hidden dangers caused by the catheter mouth being too far or too close to the seabed target position during the riprap operation in the prior art.
[0023] The depth sounder 2 is a single-beam depth sounder.
[0024] The box body 3 is formed by two symmetrically distributed shells 3b connected in a detachable manner. The above structural design facilitates the installation of the depth sounder and plays a good protective role at the same time.
[0025] The shell 3b includes a main body 3b1, and a lug 3b2 is provided on the side of the main body 3b1. The two shells 3b are connected by a first fastening bolt 3c on the lug. Therefore, the depth sounder can be disassembled and stored when not in use, and can be installed conveniently and quickly when in use.
