Technical Field

[0001] The utility model relates to the technical field of water level measurement, and more specifically, to a water level measurement device. Background Art

[0002] A pile driving boat, also known as a double pontoon, is formed by connecting two pontoons, with a gap through which a pile body passes. The gap size varies according to the pile diameter and is located below the pile hammer. Each pontoon has dimensions of 13200*900*3000 and mainly serves as an auxiliary device for pile driving. By operating the pile driving boat, the pile body is driven into the river water for installing equipment on the pile body.

[0003] When the pile driving boat travels on water, the water depth needs to be ensured. The driving depth of the pile driving boat requires the water depth to be greater than 1.1 meters to prevent the pile driving boat from running aground. Therefore, the water depth needs to be measured in advance when using the pile driving boat.

[0004] Currently, most methods for measuring water depth use a measuring ruler, which is a vertical rod inserted into the water during measurement. However, when in use, since the water depth is unknown, the length of the measuring ruler rod is generally very long, taking up a lot of space when carried, affecting portability and thus being inconvenient to use. Therefore, a water level measurement device is proposed to solve the above problems. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a water level measurement device that overcomes the above technical problems or at least partially solves the above problems.

The limiting plate is arranged on both the left and right sides of the winding roller to limit the traction rope.

[0014] In a preferred embodiment, floating blocks are fixedly installed at the bottom of the hollow bin. There are two floating blocks, which are respectively installed on both the left and right sides of the bottom of the hollow bin. The floating blocks can float the hollow bin on the water surface.

[0015] In a preferred embodiment, a cylinder is fixedly installed at the end of the traction rope. The inside of the cylinder is hollow, and water inlet holes are opened on the outer surface of the cylinder.

At the same time, this device replaces the method of measuring with a measuring rod, is convenient to carry and use.

[0021] 2. A pressure sensor is installed inside the bottom end of the hollow bin. The pressure sensor will contact the outer surface of the traction rope. When the traction rope is in a straightened state, it squeezes the pressure sensor, enabling the pressure sensor to detect the presence of pressure. When the pressure changes, the PLC controller is used to control the servo motor to stop working in a timely manner, preventing excessive release of the traction rope, which may cause the traction rope to become entangled and affect subsequent recovery.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the purpose, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] Embodiment

[0030] Refer to Figures 1-4, the present utility model provides a technical solution: a water level measuring device, including a hollow bin 1 and a measuring mechanism 3, and a servo motor 2 is fixedly installed outside the hollow bin 1. The measuring mechanism 3 includes a wire winding roller 31, which is rotatably installed inside the hollow bin 1 and is arranged at the output end of the servo motor 2. A traction rope 32 is wound around the wire winding roller 31. One end of the traction rope 32 is fixedly installed with a lead core block 321. A hollow cylinder 33 is sleeved outside the traction rope 32, and a rope displacement sensor 331 is fixedly installed inside the hollow cylinder 33. The rope end on the rope displacement sensor 331 is fixedly connected to the lead core block 321.

[0031] In a preferred embodiment, one end of the hollow cylinder 33 is fixedly connected to the bottom of the hollow bin 1. The rope displacement sensor 331 is electrically connected to a display 4, and the display 4 is fixedly installed on the top of the hollow bin 1. To facilitate the measurement of the water depth, a rope displacement sensor 331 is installed on the hollow cylinder 33, and the rope displacement sensor 331 is electrically connected to the display 4. In this way, the length of the rope pulled out inside the rope displacement sensor 331 will be displayed on the display 4 to know the water depth.

[0032] In a preferred embodiment, the output end of the servo motor 2 is fixedly connected to a round rod 5, the wire winding roller 31 is fixedly installed outside the round rod 5, and a limit plate 6 is also fixedly installed outside the round rod 5. The limit plate 6 is arranged on both the left and right sides of the wire winding roller 31 for limiting the traction rope 32. To facilitate the measurement of the water depth, the lead core block 321 and the cylinder 8 need to be sunk to the bottom of the water together. To make the two sink stably, a wire winding roller 31 is installed at the output end of the servo motor 2, and the servo motor 2 is driven to rotate the wire winding roller 31 to release the traction rope 32 on the wire winding roller 31, so as to sink the lead core block 321 and the cylinder 8 together stably into the water.

[0033] In a preferred embodiment, floating blocks 7 are fixedly installed at the bottom of the hollow bin 1. The floating blocks 7 are provided in two and are respectively installed on both the left and right sides of the bottom of the hollow bin 1. The floating blocks 7 can float the hollow bin 1 on the water surface. To facilitate the measurement of the water depth, the hollow bin 1 is placed on the water surface for use. To make the hollow bin 1 stably placed on the water surface, floating blocks 7 are installed at the bottom of the hollow bin 1. The floating blocks 7 float on the water surface, so that the hollow bin 1 will not sink, and thus the hollow bin 1 is stably placed on the water surface for use.

[0034] To improve the sinking effect of the lead core block 321, a cylinder 8 is fixedly installed at the end of the towing rope 32. The inside of the cylinder 8 is hollow, and a water inlet hole 9 is opened on the outer surface of the cylinder 8. The cylinder 8 is fixedly installed at the end of the towing rope 32. When the lead core block 321 sinks, it will drive the cylinder 8 to sink. When the cylinder 8 is completely submerged in water, water will enter the inside of the cylinder 8, thereby increasing the weight of the cylinder 8 and improving the sinking effect of the lead core block 321, so as to drive the movement of the rope inside the pull rope displacement sensor 331 through the lead core block 321, facilitating the measurement of the water depth.

[0035] When the cylinder 8 sinks to the bottom of the water, the servo motor 2 will continue to control the winding roller 31 to rotate and release the towing rope 32. To prevent excessive release of the towing rope 32, resulting in entanglement and chaos of the towing rope 32, affecting subsequent recovery, a stop mechanism 10 is installed on the hollow bin 1. The stop mechanism 10 includes a pressure sensor 101, a through hole 102, and a PLC controller 103. The through hole 102 is opened at the bottom of the hollow bin 1. The towing rope 32 is arranged inside the hollow bin 1. The pressure sensor 101 is fixedly installed inside the through hole 102. The position of the pressure sensor 101 corresponds to the position of the towing rope 32. The pressure sensor 101 is electrically connected to the PLC controller 103, and the PLC controller 103 is electrically connected to the servo motor 2.

[0036] In actual use, when the cylinder 8 touches the bottom of the water, the tension of the towing rope 32 during the release process will decrease. At this time, the pressure of the towing rope 32 on the pressure sensor 101 will decrease or will not generate pressure on the pressure sensor 101. When the pressure sensor 101 detects a change in pressure, it will control the servo motor 2 to stop working through the PLC controller 103, thereby stopping the servo towing rope 32, so that the towing rope 32 will not be released and will not cause the towing rope 32 to be entangled and knotted, so that when the cylinder 8 is pulled out later, the towing rope 32 can be normally recovered, facilitating use.

[0037] Specifically, the working process or working principle of a water level measuring device is as follows: When the piling barge travels on the water, it is necessary to ensure the water depth. The depth at which the piling barge travels needs to ensure that the water depth is greater than 1.1 meters so as not to strand the piling barge. Therefore, it is necessary to measure the water depth in advance when using the piling barge.

[0038] Currently, most of the methods for measuring the water depth use a measuring ruler. The measuring ruler is a vertical rod, which is inserted into the water during measurement to measure the water depth. However, when in use, since the water depth is unknown, the length of the measuring ruler rod is generally very long, which takes up a lot of space when carrying, affecting the carrying, and thus inconvenient to use. Therefore, this device is designed to solve this problem.

[0039] The present device facilitates water depth detection. Moreover, the device is small in size and convenient to carry, effectively replacing the use of a measuring rod. The specific operation is as follows: A storage battery is fixedly installed at the top of the hollow bin 1 of the present device to provide electrical energy for controlling the servo motor 2. The present device is placed on the river water, and the hollow bin 1 can float on the water surface through the floating block 7. A pull rope is installed on the hollow bin 1 to control the position of the hollow bin 1.

[0040] Then, turn on the servo motor 2. The servo motor 2 controls the winding roller 31 to rotate and release the traction rope 32. Driven by the lead core block 321, the traction rope 32 will be pulled downward. The lead core block 321 will sink into the water under its own weight and drive the cylinder 8 to sink into the water as well. When the cylinder 8 is completely submerged in the water, water will enter the inside of the cylinder 8 through the water inlet hole 9, thereby increasing the weight of the cylinder 8. With the combined use of the cylinder 8 and the lead core block 321, the traction rope 32 will enter the water vertically. During the downward movement of the lead core block 321, the rope inside the pull rope displacement sensor 331 will also be pulled, and the rope will be pulled downward. The water depth is measured by the length of the pulled-out rope.

[0041] As the lead core block 321 and the cylinder 8 continue to move downward, the rope will be continuously pulled. This continues until the cylinder 8 touches the bottom of the water. When the cylinder 8 touches the bottom, the traction rope 32 will continue to be released. Since the cylinder 8 will straighten the traction rope 32 and move with a certain tension during the descent, when the cylinder 8 touches the bottom, the tension of the traction rope 32 during the release process will decrease. At this time, the pressure of the traction rope 32 on the pressure sensor 101 will decrease or no pressure will be exerted on the pressure sensor 101. When the pressure sensor 101 detects a change in pressure, it will control the servo motor 2 to stop working through the PLC controller 103, thereby stopping the servo traction rope 32 to prevent the traction rope 32 from becoming entangled and affecting subsequent recovery.

[0042] During the process of the lead core block 321 pulling the rope downward, the length of the pulled-out rope will be displayed on the display 4. The staff can directly observe the value on the display 4 to know the water depth. Until the cylinder 8 touches the bottom and no longer pulls the rope, the value on the display 4 will no longer change. At this time, the water depth is the sum of the length of the pulled-out rope and the heights of the lead core block 321 and the hollow cylinder 33, which is the water depth height, facilitating the detection of the water depth and the movement of the pile driving ship on the water.

[0043] After the water depth measurement is completed, the servo motor 2 controls the winding roller 31 to reverse, pulling the traction rope 32 back and winding it around the winding roller 31 until the hollow cylinder 33 is pulled out of the water. At this time, the rope inside the pull rope displacement sensor 331 will also be recovered into the device, completing the recovery and facilitating use.

[0044] It should be noted that the servo motor 2, the wire-pulling displacement sensor 331, the display 4, the pressure sensor 101, and the PLC controller 103 are existing devices or equipment, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail herein.
