[0030] In one aspect of the embodiment of this application, please refer to Figure 1 and Figure 2 The invention provides a lead fishing trolley 100, which is arranged on two parallel tracks 200. The tracks 200 are rigid tracks and will not deform due to gravity or pressure. The lead fishing trolley 100 moves along the top surfaces of the two tracks 200.

[0031] Specifically, please refer to Figure 3 and Figure 4 The lead fish trolley 100 includes: a main beam 110 and two walking components 120 respectively arranged at opposite ends of the main beam 110, the walking component 120 includes a walking bracket 121, a walking wheel 122 and a guide wheel 123 arranged on the walking bracket 121, the walking wheels 122 on the two walking brackets 121 are respectively used to roll along the top surface of the two tracks 200, and the guide wheels 123 on the two walking brackets 121 are respectively used to roll along the side surfaces of the two tracks 200. A lead fish component 130 is also provided on the main beam 110, and the lead fish component 130 is used to extend into the water flow to obtain flow measurement data.

[0032] The two walking components 120 correspond to two tracks 200 respectively, one walking component 120 runs on the top surface of the first track 200, and the other walking component 120 runs on the top surface of the second track 200. The two walking components 120 are connected as a whole through the main beam 110, so that the two walking components 120 move synchronously.

[0033] Each traveling assembly 120 includes a traveling support 121, a traveling wheel 122, and a guide wheel 123. The traveling support 121 is connected to the end of the main beam 110, and the traveling wheel 122 and the guide wheel 123 are rotatably arranged on the traveling support 121. The track 200 has a top surface and a side surface that is at a preset angle to the top surface. After the lead fish trolley 100 is installed on the track 200, the traveling wheel 122 of one traveling assembly 120 is fitted with the top surface of the first track 200, and the guide wheel 123 is fitted with the side surface of the first track 200, and the traveling wheel 122 of the other traveling assembly 120 is fitted with the top surface of the second track 200, and the guide wheel 123 is fitted with the side surface of the second track 200. The arrangement of two traveling assemblies 120 and the cooperation of the traveling wheel 122 and the guide wheel 123 in each traveling assembly 120 can make the lead fish trolley 100 have higher stability and be less likely to shake after being impacted by an external force, thereby effectively improving the accuracy of the flow measurement data.

[0034] Preferably, the angle between the top surface and the side surface of the track 200 is 90 degrees, and the axis of the walking wheel 122 and the axis of the guide wheel 123 on the same walking assembly 120 are perpendicular to each other. Such an arrangement can further improve the stability of the lead fish trolley 100 and facilitate the installation of the walking wheel 122 and the guide wheel 123.

[0035] The main beam 110 is also provided with a lead fish assembly 130, which can extend downward from the main beam 110 to below the water surface 400, thereby obtaining the flow measurement data of the river. After being driven, the lead fish trolley 100 rolls along the track 200 via the running wheels 122 and the guide wheels 123, thereby adjusting the measurement position of the lead fish assembly 130. Generally speaking, the lead fish trolley 100 is driven by a tractor.

[0036] The above-mentioned lead fish trolley 100 is provided with two running assemblies 120, and the two running assemblies 120 correspond to two tracks 200 respectively. The running of the lead fish trolley 100 is realized by the rolling of the running wheels 122 and the guide wheels 123 along the tracks 200 on the two running assemblies 120, and the lead fish trolley 100 is free to walk, has little friction and traction, and is highly stable. It is possible to accurately control the running position of itself, reduce shaking, thereby improving the accuracy of flow measurement data. In addition, the above-mentioned lead fish trolley 100 also has the advantages of simple structure, low processing and manufacturing requirements and being easy to promote.

[0037] Alternatively, see Figure 2The guide wheels 123 on the two traveling brackets 121 are respectively used to roll along the sides of the two tracks 200 that are away from each other.

[0038] The two running brackets 121 correspond to the first track 200 and the second track 200, respectively. The guide wheels 123 on the running bracket 121 corresponding to the first track 200 are configured to roll along the side of the first track 200 facing away from the second track 200, while the guide wheels 123 on the running bracket 121 corresponding to the second track 200 are configured to roll along the side of the second track 200 facing away from the first track 200. After the fishing trolley 100 is installed, the guide wheels 123 on the two running brackets 121 sandwich the two tracks 200. Simultaneously, the running wheels 122 on the two running brackets 121 press against the top surfaces of the two tracks 200, respectively. This arrangement allows the fishing trolley 100 to remain stuck on the two tracks 200 after the guide wheels 123 are installed, thereby preventing the fishing trolley 100 from detaching from the tracks 200 during movement.

[0039] Optionally, the guide wheel 123 is detachably connected to the traveling bracket 121. Like this, the guide wheel 123 can be connected to the traveling bracket 121, easy to disassemble, and convenient to the installation and maintenance of the lead fish trolley 100.

[0040] Furthermore, please refer to Figure 3 The guide wheel 123 is detachably connected to the traveling bracket 121 through a rotating shaft 124. One end of the rotating shaft 124 fixes the guide wheel 123, and the other end passes through the traveling bracket 121 and is connected to the limiting member 125, so as to be rotatably set on the traveling bracket 121.

[0041] Alternatively, see Figure 1 and Figure 3 The number of the running wheels 122 on each running bracket 121 is at least two, and at least two running wheels 122 roll along the top surface of the track 200 at the same time.

[0042] At least two walking wheels 122 are provided on a walking bracket 121, and the at least two walking wheels 122 are spaced apart along the extension direction of the track 200. At least two walking wheels 122 roll along the top surface of the track 200 at the same time, thereby making the movement of the lead fish trolley 100 more stable and reducing the deviation and jamming of the lead fish trolley 100.

[0043] Optionally, the number of guide wheels 123 on each traveling bracket 121 is at least two, and at least two guide wheels 123 roll along the same side of the track 200 at the same time.

[0044] At least two guide wheels 123 are provided on a walking bracket 121, and the at least two guide wheels 123 are spaced apart along the extension direction of the track 200. At least two guide wheels 123 roll along the same side of the track 200 at the same time, thereby making the movement of the lead fish trolley 100 more stable and further reducing the deviation and jamming of the lead fish trolley 100.

[0045] Optionally, the traveling support 121 includes a horizontal portion 1211 and a vertical portion 1212 , the traveling wheel 122 is located on the horizontal portion 1211 , one end of the vertical portion 1212 is connected to the horizontal portion 1211 , and the other opposite end is connected to the main beam 110 .

[0046] The horizontal portion 1211 is connected to the main beam 110 via the vertical portion 1212. The horizontal portion 1211 is parallel or nearly parallel to the track 200. The running wheels 122 are mounted on the horizontal portion 1211, allowing the vehicle to travel along the track 200. The vertical portion 1212 extends downward from the horizontal portion 1211 and connects to the main beam 110, thereby allowing the main beam 110 to avoid interference with the track 200.

[0047] Alternatively, see Figure 3 and Figure 4 The lead fish assembly 130 includes a sliding wheel 131, a cable 132, a lead fish 133 and a measuring instrument. The sliding wheel 131 is rotatably set on the main beam 110, the cable 132 is wound around the sliding wheel 131, the lead fish 133 is connected to the cable 132, and the measuring instrument is set on the lead fish 133.

[0048] Sliding wheel 131 rotates clockwise or counterclockwise to retract and extend cable 132. A lead fish 133 is attached to the end of cable 132, allowing it to adjust its height during retraction and extension. A measuring instrument is mounted on lead fish 133, which can acquire flow data. Lead fish 133, carrying the measuring instrument, is lowered 400° below the water surface to measure the current.

[0049] Optionally, a traction assembly 140 is further provided on the main beam 110, and the traction assembly 140 is used to connect to a tractor.

[0050] The tractor pulls the lead fish trolley 100 along the track 200 through the traction assembly 140 , thereby adjusting the horizontal position of the lead fish assembly 130 .

[0051] Optionally, the traction assembly 140 includes a traction bracket 141 and a traction rope 142. The traction bracket 141 is disposed on the main beam 110. One end of the traction rope 142 is connected to the traction bracket 141, and the other end is connected to a tractor.
