Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an electric cutting device for thinning and cutting aquatic plants in aquaculture. Background Technology

[0002] In aquaculture, aquatic plants are a key element in maintaining the ecological balance of ponds. Taking shrimp and crab farming as an example, aquatic plants regulate dissolved oxygen concentration through photosynthesis, absorb excess nitrogen, phosphorus and other nutrients in the water, and provide habitats, predator shelters and foraging grounds for farmed organisms.

[0003] However, excessive growth of aquatic plants can lead to a series of problems, such as water quality deterioration. After the aquatic plants cover the water surface, they consume a lot of oxygen through respiration at night, leading to oxygen deficiency in the water and causing farmed organisms to float to the surface or even die. When the aquatic plants go beyond the water surface, they are prone to rotting, releasing toxic substances and disrupting the chemical balance of the water.

[0004] Therefore, regularly adjusting the density of aquatic plants is a core aspect of aquaculture management. Traditional manual pruning methods rely on boats and manual tools, which suffer from low efficiency, high labor intensity, and poor cutting precision. Utility Model Content

Detailed Implementation

[0025] This utility model embodiment provides an electric cutting device for thinning and cutting aquatic plants in aquaculture, such as... Figure 1-5 As shown, the device includes a base plate 101. One end of the base plate 101 has an arc-shaped guide port 102 with an outward opening. The center of the arc-shaped guide port 102 has an outward-opening converging cavity 105. A cutting motor 109 is fixedly installed at the center of the top of the base plate 101. A waterproof sealing plate 117 is fixedly installed at the connection between the lower end of the cutting motor 109 and the top of the base plate 101. The waterproof sealing plate 117 has a sealing and waterproofing effect. A power shaft 116 is connected to the bottom of the cutting motor 109. The lower end of the power shaft 116 passes through the base plate 101 and extends downward. Several arc-shaped cutting plates 115 are fixedly connected to the outer end face of the power shaft 116. The cutting plates 115 are arranged in a circular array. Each side of the cutting plate 115 has a cutting blade 114 on its inner arc surface.

[0026] It should be further explained that the opening of the arc-shaped guide 102 is larger than that of the gathering cavity 105. The arc-shaped guide 102 plays a guiding and gathering role for the aquatic plants, while the gathering cavity 105 plays a role in uniformly gathering the aquatic plants, thereby facilitating the subsequent cutting effect.

[0027] It is worth further explaining that when the cutting motor 109 starts, it can drive the power shaft 116 to rotate through the power connection, and then drive the cutting plates 115 on each side to rotate through the power shaft 116 to achieve the cutting effect. When the cutting blade 114 rotates, it can perform a precision cutting of aquatic plants.

[0028] Furthermore, two arc-blocking plates 103 are fixedly provided on both sides of the bottom of the device base plate 101, and the arc-blocking plates 103 on both sides are symmetrically arranged.

[0029] Furthermore, ultrasonic sensors 104 are fixedly installed on both sides of the arc-blocking plates 103, close to each other. The ultrasonic sensors 104 on both sides are located below the arc-shaped guide 102, and the ultrasonic sensors 104 on both sides are symmetrically arranged.

[0030] It should be further explained that the ultrasonic sensor 104 is an ultrasonic aquatic plant density monitoring sensor. It emits ultrasonic pulses of a specific frequency, penetrates the water body, and receives the echo signal reflected by the aquatic plant layer. It calculates the density and thickness of the aquatic plants by using the signal attenuation and time difference.

[0031] Furthermore, a speed controller 110 is installed and connected to the top of the device base plate 101 and to the side of the cutting motor 109.

[0032] It should be further explained that the ultrasonic sensor 104 has a built-in signal processing module that can convert analog signals into digital density values ​​and transmit them wirelessly to the speed controller 110. The speed controller 110 receives the signal from the ultrasonic sensor 104 and controls the start speed of the cutting motor 109.

[0033] Furthermore, a handheld lever 106 is fixedly provided on one side of the top of the device base plate 101, and the handheld levers 106 are distributed in an array.

[0034] Furthermore, a connector 107 is fixedly installed on one side of the top of the device base plate 101. The connector 107 is L-shaped, and a threaded mounting plate 108 is installed on the tail end of the ultrasonic sensor 104.

[0035] Furthermore, the threaded mounting plate 108 is provided with a number of outward-facing threaded holes 111, and the positions of the threaded holes 111 are arranged in an array.

[0036] It should be further noted that the threaded hole 111 facilitates connection to the vessel via screws.

[0037] Furthermore, two rotating shafts 112 are rotatably connected to one side of the bottom of the device base plate 101. The rotating shafts 112 on both sides are symmetrically arranged, and an arc-shaped protective plate 113 is fixedly connected to the outer end face of the rotating shafts 112.

[0038] The usage method of this solution is as follows:

[0039] S1. Operators should select the appropriate installation method based on the size of the aquaculture pond, the type of boat, and their personal operating habits.

[0040] Check the wiring connection of the cutting motor 109, the power supply and signal reception status of the speed controller 110 to ensure that the waterproof sealing plate 117 is properly sealed.

[0041] If the device needs to be fixed to the boat, use matching bolts or screws through the threaded holes 111 on the threaded mounting plate 108 to firmly install the entire device on the pre-set bracket or platform at the bow or side of the boat, ensuring that the device is at a suitable depth below the water surface, so that the lower edge of the arc-shaped guide 102 is slightly lower than the expected top of the aquatic plant canopy, and the arc-shaped guide 102 faces the direction of the boat's movement.

[0042] When used for handheld operation, for small areas or delicate tasks, the operator can directly hold the hand lever 106 and immerse the device in water for operation. The array distribution of the hand lever 106 provides a stable grip point and lever support, making it easy to control the direction.

[0043] S2. Operators drive boats or use handheld devices to wade through the water and smoothly enter the target aquaculture area where the density of aquatic plants needs to be adjusted.

[0044] During the cutting of aquatic plants, the ultrasonic sensors 104 located on the baffle plates 103 on both sides of the bottom of the device work continuously. They emit ultrasonic pulses of a specific frequency to the water below and in front to monitor the density of the aquatic plant layer.

[0045] S3. The ultrasonic sensor transmits the real-time digital density value obtained to the speed controller 110 on the top of the device wirelessly.

[0046] The speed controller 110 processes the received density data according to a preset cutting strategy algorithm;

[0047] When the density and thickness of aquatic plants are detected to exceed the set threshold, the speed controller 110 automatically outputs a control signal with a higher speed to the cutting motor 109, driving it to run at high speed. This ensures that a large number of aquatic plant stems and leaves can be cut quickly and effectively in areas with high density aquatic plants, improving work efficiency and avoiding device blockage.

[0048] When the density of aquatic plants is detected to be below the set threshold or within a reasonable range, the controller can reduce the speed of the cutting motor 109 to a low speed or even put it into standby mode. This avoids unnecessary cutting actions, ensures precise operation, saves energy, reduces interference with sparse aquatic plants, and protects the beneficial aquatic plant area.

[0049] S4. As the device moves forward with the boat or handheld, the stems and leaves of the aquatic plants in front first come into contact with the arc-shaped guide 102. The arc-shaped design of this guide effectively and gently guides the scattered aquatic plants to gather together, reducing the tangling and resistance of the aquatic plants at the inlet;

[0050] The gathered aquatic plants then enter the smaller converging cavity 105. This structure further concentrates and organizes the aquatic plants, forming a relatively uniform "bundle" or "sheet" flow, which creates favorable conditions for subsequent precise cutting.

[0051] S5. Behind the receiving cavity 105, the high-speed rotating cutting plate 115 driven by the cutting motor 109 through the power shaft 116 and the cutting blade 114 on its inner arc surface become the core cutting components.

[0052] The circular array of cutting plates 115 forms a rotating cutting surface, and the waterweed flow that has been regulated by the converging cavity is forcibly guided through this high-speed rotating cutting surface.

[0053] The 114-blade cutting blade, with its sharp edge, rotates at high speed like a pair of scissors, efficiently and neatly cutting through the stems and leaves of aquatic plants. The cutting precision is significantly higher than that of traditional hand tools, resulting in clean cuts and reducing tearing damage to the aquatic plants.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
