Description

Technical Field

[0001] This utility model relates to the technical field of ice-covered netting equipment, specifically to an ice-covered positioning and searching device for an ice-covered netting machine. Background Technology

[0002] Net-laying machines are mainly used for setting up fishing nets, especially in the Northeast region during winter. Due to the cold climate, the water surface often freezes over with a thick layer of ice, making conventional net-laying operations impossible. A net-laying machine is then used to deploy the net. One end of the fishing net's lead line is attached to the machine, and holes are drilled in the ice. The machine is then lowered under the ice, moving across the water beneath the ice to allow the lead line to unfurl properly. Once the lead line is in the water, the machine is positioned again to continue drilling holes and deploying the net. After the net-laying machine is taken out, the fishing net is connected to one end of the lead line. Then, the lead line is pulled to pull the entire net under the ice and spread it out. When the net-laying machine moves under the ice, its position is prone to shift. To take out the net-laying machine, its position under the ice must be accurately located first. However, in some areas, due to the large amount of impurities in the water, the ice layer is generally turbid after freezing. In addition, sometimes after snowfall, the ice surface is covered with a thick layer of snow, which makes it impossible for the net-laying personnel to accurately locate the position of the net-laying machine through the ice or snow layer. This causes great inconvenience to the net-laying operation. Utility Model Content

[0018] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-2 As shown, this utility model embodiment provides an ice-sealing and net-laying machine positioning and locating device, including a float 1 with an internal cavity, a walking device on the outside of the float 1 to drive the float 1 to move on the water surface under the ice, an upward-protruding mounting base 2 on the top of the float 1, a metal signal transmitting bracket 3 on the mounting base 2, a signal transmitter 4 in the inner cavity of the float 1, a wire at one end of the signal transmitter 4 connected to the signal transmitting bracket 3, and a cable 5 connected to the wire at the other end of the signal transmitter 4. The cable 5 extends outward from the float 1 and is located by a receiver 6.

[0021] Preferably, the signal transmitter 4 is a line finder transmitter.

[0022] The signal transmitter 4 is powered by a battery inside the float 1. When the cable 5 is energized, the emitted electromagnetic signal is received by the receiver 6. The electromagnetic wave signal emitted by the cable 5 also propagates in the water or ice. These electromagnetic wave signals are received by the signal transmitting bracket 3 to form a loop. The signal transmitting bracket 3 also emits electromagnetic wave signals. In this way, the receiver 6 can sense the cable and the signal transmitting bracket 3 through the electromagnetic wave signals. Furthermore, this device can emit electromagnetic wave signals and be received by the receiver 6 whether it is stationary or moving under the ice. This device is an existing device, and its specific structure and principle will not be described in detail here.

[0023] Preferably, the signal transmitting bracket 3 is made of metal wire.

[0024] The length of cable 5 is selected according to the length of the fishing net. One end of cable 5 enters the water under the ice along with the float 1, and the other end is placed on the ice surface. In order to facilitate the management of cable 5, the part of cable 5 on the ice can be coiled on the reel.

[0025] The two ends of the signal transmitting bracket 3 extend vertically downward into the cavity of the float 1. The middle part of the signal transmitting bracket 3 extends out above the mounting base 2. The wire at one end of the signal transmitter 4 is connected to the part of the signal transmitting bracket 3 located inside the float 1. The signal transmitting bracket 3 is made of metal wire bent into a U-shape. Its horizontal wire extends outward from the upper end of the mounting base 2, and its vertical wires on both sides extend into the cavity of the float 1.

[0026] Two signal transmitting brackets 3 are symmetrically arranged on the mounting base 2. The portions of the two signal transmitting brackets 3 located inside the mounting base 2 are connected by a metal plate 7. The wire at one end of the signal transmitter 4 is connected to the metal plate 7. The metal plate 7 allows the signal transmitting brackets 3 on both sides to be connected in series.

[0027] The wire at the other end of the signal transmitter 4 extends downwards towards the float 1, and the cable 5 is also located at the lower end of the float 1.

[0028] The walking device includes walking wheels 8 symmetrically arranged on both sides of the float 1. The outer circumference of the walking wheels 8 is provided with teeth. The two walking wheels 8 are connected by a connecting shaft that is horizontally placed in the float 1 in the front-back direction. The part of the connecting shaft located in the float 1 is also provided with a transmission wheel. The transmission wheel is driven to rotate by a walking motor.

[0029] The top of the float 1 is also provided with an installation chamber 9, and a steering motor is installed inside the installation chamber 9. The shaft of the steering motor is connected to a coupling 10, which extends out of the installation chamber 9. A steering wheel 11 is installed at the end of the coupling 10 located outside the installation chamber 9.

[0030] The mounting compartment 9 is located at the front end of the mounting base 2. A rotating shaft 12 is horizontally placed in the middle of the mounting base 2. The steering wheel 11 is installed at the rear end of the rotating shaft 12. The front end of the rotating shaft 12 is connected to the coupling 10.

[0031] The utility model patent application with application number CN202220470935.6, entitled "A Netting Device for Ice Covering", discloses the structure of a netting device. The application details the driving structure of the walking wheel 8 and the driving structure of the rotating disc 11. Therefore, the above-mentioned driving structure is not shown in the accompanying drawings of this application.

[0032] The walking device is located at the front end of the float 1, and the mounting base 2 and the signal transmitting bracket 3 mounted on it are located at the rear end of the float 1.

[0033] The float 1 is a cylindrical structure with openings at the front and rear. The float 1 has a cone-shaped front cover 13 at the front opening and a detachable rear cover 14 at the rear opening. The float 1 has symmetrical stabilizer wings 15 on both sides of the rear end.

[0034] The float 1 is provided with a connector 16 at its moving end for connecting a lead wire.

[0035] The working principle of this utility model is as follows: The lead wire for netting is installed at the connector 16 of the float 1. An ice hole is made at one end of the ice surface. Then, the entire float 1 is placed in the water under the ice. The movement device of the float 1 is activated, and at the same time, the signal transmitter 4 is also activated, so that the float 1 moves on the surface of the water under the ice. During the movement of the float 1, it will pull the lead wire to unfold under the ice. When the float 1 moves, it will also pull the cable 5 to move and unfold under the ice. When the float 1 has fully unfolded the lead wire, the workers may not be able to find the float 1 with the naked eye due to the ice being dirty, having poor light transmission, or being covered with snow. In this case, the netting personnel can walk on the ice with the receiver 6 in hand, with the sensing end of the receiver 6 facing the ice. In the layout, when the cable locator generator is activated, it causes the cable 5 and the signal transmitting bracket 3 to emit electromagnetic wave signals. The closer the receiver 6 is to the cable 5, the louder its alarm sound becomes. Outside a certain range of the cable 5, the receiver 6 has no sensing signal. Thus, the cable laying personnel can determine the position of the cable based on the alarm sound of the receiver 6 and move along the position of the cable 5 under the ice until they find the float 1. After determining the position of the float 1, they continue to break through the ice layer where the float 1 is located and take out the float 1. The whole process makes it convenient for the cable laying personnel to quickly determine the direction and position of the float 1, so that the position of the float 1 can be quickly determined in the case of low visibility due to ice, which greatly facilitates the locating of the float 1.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
