Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sonar, in particular to a fish finding sonar device for fisheries. Background Art
[0002] With the continuous development of the national economy and the continuous increase in population, the demand for resources is increasing year by year. As a key component of this demand, oceans, rivers, reservoirs and other resources are increasingly valued. At the same time, how to effectively and efficiently utilize the fish resources in oceans, rivers and other places has also become a major issue facing people.
[0003] In traditional fishing and fish farming operations, fishermen rely primarily on experience and observation. For example, they use weather, temperature, fish jumping out of the water, and shadows beneath the surface to determine the direction, type, and number of fish. This traditional method carries significant uncertainty, leading fishermen to seek high-tech fish-finding equipment to assist them in fishing and fish farming. Fish-finding sonar was designed with this in mind. Using the principles of sonar detection, fish-finding sonar can effectively detect the distribution of fish and water conditions while a vessel is sailing. This allows fishermen to plan their fishing and other operations based on these detection results, making fishing and fish farming more convenient and efficient, significantly increasing fishermen's returns.
[0004] However, existing fish-finding sonars are generally large in size and are usually installed on ships. Fish-finding sonars are used in open waters, such as oceans and rivers, to assist in finding the location of fish schools. Therefore, a small, portable fish-finding sonar is needed for use in fish ponds to conduct qualitative analysis of the water depth in the fish pond and the depth and activity of fish, providing an intelligent detection method for fishery farming.

[0029] a detection device 2 disposed outside the housing 1 and comprising a piezoelectric ceramic ultrasonic transducer 201 and an acoustically transparent cover 202. The acoustically transparent cover 202 is detachably connected to the housing 1 and is sealed to the housing 1. The piezoelectric ceramic ultrasonic transducer 201 is disposed within the acoustically transparent cover 202.
[0030] The controller 3 is arranged inside the shell 1, and the controller 3 is communicatively connected with the piezoelectric ceramic ultrasonic transducer 201. The controller 3 is also provided with a signal cable 301, one end of which passes through the shell 1 and extends out of the outside of the shell 1.
[0031] The present invention provides a fish-finding sonar device, characterized by comprising: a housing 1, a detection device 2, and a controller 3. The detection device 2 includes a piezoelectric ceramic ultrasonic transducer 201 and a sound-transmitting cover 202. The ultrasonic transducer can convert electrical energy into mechanical energy, thereby generating ultrasonic waves in water, and can also receive ultrasonic signals and convert mechanical energy back into electrical energy. Piezoelectric ceramics are functional ceramics that are highly sensitive to the physical quantities of electricity and pressure. When a piezoelectric ceramic is subjected to an external force, the positive and negative charges within it converge on both sides, forming a potential difference, a process of converting mechanical energy into electrical energy.

The piezoelectric ceramic ultrasonic transducer 201 has high transmission efficiency when used as a transmitter, high sensitivity when used as a receiver, and a relatively wide operating frequency band. By setting the piezoelectric ceramic ultrasonic transducer 201, the overall volume of the fishery fish finding sonar device can be effectively reduced, which can be miniaturized and easy to carry; the material of the sound-transmitting cover 202 is a rubber material with good sound-transmitting function. The sound-transmitting cover 202 can not only seal the piezoelectric ceramic ultrasonic transducer 201, so that it can be used normally in deep water areas, but also avoid affecting the piezoelectric ceramic ultrasonic transducer 201 from emitting and receiving ultrasonic waves, thereby avoiding affecting the detection accuracy; the controller 3 is used to control the piezoelectric ceramic ultrasonic transducer 201 to emit ultrasonic waves, and process the ultrasonic waves received by the piezoelectric ceramic ultrasonic transducer 201, and transmit the processed data to other supporting equipment through the signal cable 301.
