DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and drawings, and the schematic embodiments of the present application and the description thereof are only used to explain the present application, and do not limit the present application.

[0030] Embodiment:

[0031] As Figures 1-5As shown, a working ship for pseudo-random flow field method measurement comprises a ship body 1, a measurer 2, a wire winder 3 and a driver 4;

[0032] The measurer 2 comprises an auxiliary block 210 and a guide wire 220, the auxiliary block 210 is arranged on the side of the ship body 1, and an inner groove 201 is arranged on the outer surface of the auxiliary block 210, and the guide wire 220 is slidingly arranged on the inner groove 201;

[0033] The wire winder 3 is arranged on the ship body 1 and used to drive the measurer 2 to move up and down, and the driver 4 is arranged on the ship body 1 and used to drive the ship body 1 to move.

[0034] In view of the problem of wire abrasion in the prior art, the auxiliary block 210 is arranged in the measurer 2, which is used to separate the ship body 1 and the guide wire 220 to avoid direct contact between the guide wire 220 and the ship body 1, and the inner groove 201 is arranged on the auxiliary block 210 to guide and limit the guide wire 220 to avoid the guide wire 220 from being separated. Thus, the guide wire 220 is protected, the abrasion of the guide wire 220 is reduced, the service life of the guide wire 220 is prolonged, the measurement error caused by the abrasion of the guide wire 220 is avoided, and the measurement accuracy is improved.

[0035] It is easy to understand that the guide wire 220 can be selected as a copper wire or any other suitable existing conductive wire material.

[0036] Specifically, the measurer 2 is used to measure data, the wire winder 3 is used to drive the measurer 2 to move up and down, so that the measurer 2 measures at different water depths, thereby measuring at different water depth positions of the same measurement point. The driver 4 is used to drive the ship body 1 to move to different measurement points, thereby measuring at multiple measurement points.

[0037] In operation, the staff drives the ship body 1 to move to one of the measurement points by operating the driver 4, and then lowers the measurer 2 to the bottom of the measurement point by the wire winder 3 to record the water depth data. According to the interval set by the survey or detailed survey requirement, the wire winder 3 moves the measurer 2 to a certain height to collect and record the potential difference value at the height, and generally three values are collected to obtain an average value. Then the wire winder 3 moves the measurer 2 to rise, collects and records the potential difference value of the next point, and so on until the measurer 2 floats out of the water.

[0038] At this time, it means that the measurement operation of the measurement point is completed, and the staff recovers each device to the ship body 1. The staff drives the ship body 1 to move to the next measurement point by operating the driver 4, and repeats the above operation to complete the measurement operation.

[0039] In one possible implementation, the auxiliary block 210 includes a top plate 211, a buckle plate 212, and an auxiliary plate 213; the two ends of the bottom surface of the top plate 211 are respectively connected to the buckle plate 212 and the auxiliary plate 213, and correspondingly, a buckle groove 202 for connecting the side of the hull 1 is provided between the buckle plate 212 and the auxiliary plate 213; the outer surface of the auxiliary plate 213 is provided with the inner groove 201.

[0040] Based on the above design, the fastening plate 212 and the auxiliary plate 213 are spaced apart to form a fastening groove 202. The fastening groove 202 is fitted onto the side of the hull 1 to connect the auxiliary block 210 to the hull 1. Furthermore, the auxiliary block 210 can also move along the side of the hull 1 through the fastening groove 202, thereby adjusting the position of the auxiliary block 210 on the hull 1, and thus adjusting the position between the auxiliary block 210 and the wire 220, so as to improve the performance of the auxiliary block 210.

[0041] Optionally, such as Figure 2 As shown, the buckle plate 212 is constructed as a frame structure, which achieves weight reduction while ensuring connection. Furthermore, the auxiliary plate 213 is longer than the buckle plate 212 to extend the length of the inner groove 201 and better guide the extension direction of the guide line 220.

[0042] In one possible implementation, the measuring device 2 includes a receiver 230, a probe 240, and a conductive sheet 250. The receiver 230 is mounted on the hull 1, and the probe 240 has two spaced conductive sheets 250. Each conductive sheet 250 is connected to the receiver 230 via a wire 220. Correspondingly, the probe 240 is connected to the winding device 3. The receiver 230, the wire 220, and the conductive sheet 250 form a measuring circuit.

[0043] Based on the above design, receiver 230 is mounted on the hull 1 and operated by personnel to measure and display the potential difference value. It is easy to understand that receiver 230 can be any suitable existing model. Probe 240 and conductive sheet 250 are the parts of measuring device 2 that sink underwater. Rope reel 3 is connected to probe 240, thereby controlling the position of probe 240 in the water. Probe 240 can be made of any suitable material and constructed in any suitable shape. Conductive sheet 250 includes, but is not limited to, copper sheet. Simultaneously, two conductive sheets 250 and two wires 220 are interconnected to form a closed loop, thereby realizing the measurement of the potential difference value. Correspondingly, two auxiliary blocks 210 are also provided.

[0044] In operation, the staff member lowers the probe 240 into the water, and at this time, it should be noted that the two wires 220 are respectively threaded through the inner grooves 201 of the two auxiliary blocks 210, so as to ensure that the wires 220 do not contact the ship body 1. The staff member operates the winch 3 to lower the probe 240 until the probe 240 sinks to the bottom. Then, the probe 240 is moved upward by a certain distance in the reverse direction, and the receiver 230 is operated to measure the potential difference value, so as to collect and record the potential difference value at this position. The above operation is repeated until the measurement at the measurement point is completed

[0045] In a possible implementation, the winch 3 comprises a mounting seat 301, a winch body 302, and a hand crank 303. The mounting seat 301 is arranged on the ship body 1. The winch body 302 is connected to the mounting seat 301 through a rotating shaft 304. Correspondingly, the winch body 302 is arranged to rotate on the rotating shaft 304. The winch body 302 is wound with a rope 305 for connecting the probe 240. The hand crank 303 is connected to the rotating shaft 304 and is used to rotate the winch body 302, so as to wind or release the rope 305.

[0046] Based on the above design scheme, the mounting seat 301 is used to connect the ship body 1, and can be constructed in any suitable shape. The winch body 302 is wound with the rope 305, the probe 240 is connected through the rope 305, and the probe 240 is raised or lowered through winding or releasing of the rope 305. It is easy to understand that the winch body 302 and the rope 305 can be selected as any suitable existing model, respectively. The hand crank 303 is used by the staff member to control winding or releasing of the rope 305 by rotating the hand crank 303.

[0047] It is worth noting that, for the same measurement point, multiple measurements need to be performed at different heights. In the prior art, the operation is performed by manual lifting. The problem of manual lifting is that the accuracy is poor, and the set point position deviates greatly. Moreover, manual lifting exists shaking and causes the water near the probe 240 to shake, so that the measurement result is not accurate enough.

[0048] In view of this, in a possible implementation, the circumference of the winch body 302 is a fixed value, and the rope 305 is provided with a scale value. Correspondingly, the circumference of the winch body 302 is compared with the scale value of the rope 305, so that the rotation length of the winch body 302: the lowering value of the rope 305 = 1:1.

[0049] Based on the above design scheme, for the staff, the length of the winding handle 303 is known when the winding handle 303 is shaken to rotate the winding body 302 for one turn, which is used as a reference for the wire release. At the same time, with the scale value on the rope 305, when the probe 240 is lowered to the bottom of the measurement point, not only the water depth data can be recorded, but also the winding body 302 is adjusted to make the rotation length of the winding body 302 correspond to the scale value of the rope 305, and the position of the probe 240 is reflected by the number of turns of the winding body 302.

[0050] For example, it is assumed that each turn of the winding body 302 is fixed at 0.5 m, and the detailed inquiry interval is 0.25 m. Therefore, during the measurement operation, the staff can stop after shaking half a turn each time. Thus, the randomness of the measurement operation is smaller, and the measurement result is more accurate.

[0051] Further, in cold regions, the manual pulling method is easy to cause frostbite to the body, and the labor intensity is too large, and the measurement efficiency is low. The winding device 3 replaces manual work, which not only protects the health of the staff, but also improves the measurement efficiency.

[0052] For the prior art, when moving to the next measurement point, the staff usually pulls the measuring rope for help or paddles the kayak. It is time-consuming and labor-intensive, and it is difficult to control the direction, and a lot of time is often consumed in the moving process.

[0053] In view of this, in a possible implementation manner, the driver 4 includes a console 410, a driving device 420 and a guide device 430; the console 410, the driving device 420 and the guide device 430 are all arranged on the ship body 1, the console 410 is electrically connected to the driving device 420, the driving device 420 is used to drive the ship body 1 to move, and the guide device 430 is used to guide the moving direction of the ship body 1.

[0054] Based on the above design scheme, the direction is guided by the guide device 430, the staff controls the power of the driving device 420 by controlling the console 410, and then controls the speed and direction of the ship body 1, thereby saving labor and improving work efficiency.

[0055] It is easy to understand that the console 410 and the driving device 420 are respectively selected from any suitable existing device.

[0056] For the guide device 430, in a possible implementation manner, the guide device 430 includes a guide cylinder 431 and a guide rope 432; the guide cylinder 431 is arranged on the ship body 1, and the guide rope 432 is located outside the ship body 1 and is arranged on the guide cylinder 431.

[0057] According to the above design scheme, the measuring route is planned according to the positions of the measuring points, the guide rope 432 is arranged according to the measuring route, the guide cylinder 431 is sleeved on the guide rope 432 and connected with the ship body 1, so that the ship body 1 moves along the guide rope 432, and the moving direction of the ship body 1 is guided.

[0058] As shown in Figure 5 The guide cylinder 431 comprises a fixed part 401 and a rotating part 402; the fixed part 401 is connected with the ship body 1, and the rotating part 402 has two ends, one end of which is a connecting end rotatably connected with the fixed part 401, and the other end is a free end detachably connected with the fixed part 401; accordingly, the rotating part 402 can rotate relative to the fixed part 401 to control the opening and closing of the guide cylinder 431.

[0059] Specifically, the rotating part 402 has a first station in which the free end is connected with the fixed part 401, and a second station in which the free end is separated from the fixed part 401.

[0060] Accordingly, when the rotating part 402 is in the first station, the fixed part 401 is connected with the rotating part 402 and forms the cylindrical guide cylinder 431.

[0061] According to the above design scheme, the operator controls the opening and closing of the guide cylinder 431 by operating the rotating part 402, and then controls the connection between the ship body 1 and the guide rope 432; before and after the measuring operation, the guide cylinder 431 is separated from the guide rope 432, and the ship body 1 moves more freely; otherwise, during the measuring operation, the guide cylinder 431 is connected with the guide rope 432, so that the ship body 1 moves along the planned route.

[0062] In one possible implementation, the rotating part 402 is connected with the fixed part 401 by buckling or magnetic attraction. It is easy to understand that the rotating part 402 can also be connected with the fixed part 401 by any other suitable means.

[0063] The above specific embodiments further illustrate the purpose, technical scheme and advantages of the present application. It should be understood that the above description is only a specific embodiment of the present application and does not limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
