Technical Field
[0001] This utility model relates to the field of aquatic ecological management equipment technology, and in particular to an underwater towing and collection device for cleaning aquatic plants. Background Technology
[0002] With the combined effects of accelerated industrialization, intensified agricultural non-point source pollution, and climate change, the aquatic ecological environment has undergone significant changes, and the problem of excessive aquatic plant growth is becoming increasingly prominent. This seemingly natural biological reproduction phenomenon actually causes a series of chain-like negative impacts on the aquatic ecosystem and its surrounding environment.
[0003] Existing aquatic plant cleaning methods use underwater towing and collection devices, which have insufficient propulsion power and are prone to obstruction in areas with dense aquatic plants. They also have poor stability during towing. Furthermore, poor drainage in the collection chamber increases the underwater towing resistance of the device, and unloading the collected aquatic plants is inconvenient. Utility Model Content
[0004] The purpose of this invention is to solve the problem of insufficient traction and propulsion power in existing devices, and to propose an underwater towing and traction collection device for cleaning aquatic plants.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an underwater towing and traction collection device for cleaning aquatic plants, comprising a collection box, a mounting cavity, and a traction assembly. The mounting cavity is provided at the back end of the collection box. The traction assembly is fixedly connected to the inner bottom wall of the mounting cavity. The traction assembly includes a motor box fixedly connected to the inner bottom wall of the mounting cavity. A servo motor is fixedly connected to the inner wall of the motor box. A push rod is fixedly connected to the output end of the servo motor. A transmission belt is rotatably connected to the surface of the push rod. A synchronization rod is rotatably connected to the other end of the inner wall of the transmission belt. Push blades are fixedly connected to the surfaces of the push rod and the synchronization rod. A fixing ring is fixedly connected to the top of the collection box. A towing steel cable is fixedly connected to the top of the fixing ring.
[0006] Furthermore, each of the push rod and the synchronizing rod has two limiting discs fixedly connected to its surface, and the two limiting discs are in contact with the transmission belt.
[0007] Furthermore, two annular grooves are formed on the surface of the synchronizing rod, and rotating ring blocks are rotatably connected to the inner walls of the two annular grooves.
[0008] Furthermore, a support frame is fixedly connected to the surfaces of the two rotating blocks, and a collection compartment is provided inside the collection box.
[0009] Furthermore, a baffle is slidably connected to the inner top wall of the collection chamber outlet, and a sliding plate is fixedly connected to the top of one side of the baffle.
[0010] Furthermore, a telescopic device is fixedly connected to the bottom of the slide plate, and a cavity is provided on the side wall of the outlet end of the collection chamber. The bottom of the telescopic device is fixedly connected to the inner bottom wall of the cavity.
[0011] Furthermore, a groove is provided on the other side of the baffle, and a slider is fixedly connected to the other side wall of the outlet end of the collection chamber. The inner wall of the groove and the surface of the slider are slidably connected. A drain outlet is provided on the inner bottom wall of the collection chamber, and a filter screen is fixedly connected to the inner wall of the drain outlet.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting up a traction component, the motor box inside the mounting cavity can protect the servo motor. The servo motor drives the push rod to rotate, and the transmission belt drives the synchronous rod to rotate synchronously, so that the push fan blades on the surface of the push rod and the synchronous rod rotate simultaneously, generating a strong propulsion force, enhancing the device's underwater propulsion power, and facilitating movement in areas with dense aquatic plants.

The synergistic effect of propulsion and towing improves the range and efficiency of aquatic plant collection. The limiting plate fits the transmission belt to prevent it from shifting and falling off during rotation, ensuring that the push rod and the synchronous rod are synchronized. The rotating ring block rotates in the ring groove, cooperating with the support frame to support the synchronous rod, ensuring its rotational stability. The collection chamber collects aquatic plants, and the filter screen discharges water from the chamber through the drain, reducing underwater towing resistance. The telescopic device extends and retracts, driving the slide plate and baffle to move. The sliding groove and the slider cooperate to ensure the baffle slides smoothly, facilitating the opening of the collection chamber outlet for unloading. This structure significantly improves the efficiency of aquatic plant cleaning and the ease of operation by strengthening propulsion power and optimizing transmission and drainage.

[0021] Please see Figure 1-5 This utility model provides a technical solution: an underwater dragging and traction collection device for cleaning aquatic plants, including a collection box 1, a mounting cavity 2 and a traction component 3. The mounting cavity 2 is opened at the back end of the collection box 1, and the traction component 3 is fixedly connected to the inner bottom wall of the mounting cavity 2.
[0022] The specific settings and functions of its traction component 3 will be discussed below.
[0023] In this embodiment: the traction assembly 3 includes a motor box 31 fixedly connected to the bottom wall of the mounting cavity 2. A servo motor 32 is fixedly connected to the inner wall of the motor box 31. A push rod 33 is fixedly connected to the output end of the servo motor 32. A transmission belt 34 is rotatably connected to the surface of the push rod 33. A synchronization rod 35 is rotatably connected to the other end of the inner wall of the transmission belt 34. A push fan blade 36 is fixedly connected to the surface of the push rod 33 and the synchronization rod 35. A fixed hanging ring 37 is fixedly connected to the top of the collection box 1. A towing steel cable 38 is fixedly connected to the top of the fixed hanging ring 37.
[0024] The effect achieved by the above components is as follows: the servo motor 32 can be protected by the motor box 31. The servo motor 32 drives the push rod 33 to rotate, and the transmission belt 34 drives the synchronous rod 35 to rotate synchronously, so that the push blades 36 on the surface of the push rod 33 and the synchronous rod 35 rotate to generate propulsion force. The towing steel cable 38 connected by the fixed hanging ring 37 cooperates with the propulsion force to realize the underwater towing movement of the device, which is convenient for collecting aquatic plants.
[0025] Please see Figure 5 Specifically, the surfaces of the push rod 33 and the synchronizing rod 35 are each fixedly connected to two limiting discs 4, and the two limiting discs 4 are in contact with the transmission belt 34.
[0026] The effect achieved by the above components is as follows: by setting the limiting plate 4 to fit the transmission belt 34, the axial movement of the transmission belt 34 is restricted, preventing it from deviating and falling off during rotation, ensuring that the push rod 33 and the synchronization rod 35 are synchronized, and improving the propulsion stability.
[0027] Please see Figure 5Specifically, the surface of the synchronizing rod 35 has two annular grooves 5, and the inner walls of the two annular grooves 5 are rotatably connected to rotating ring blocks 6.
[0028] The effect achieved by the above components is as follows: by setting the annular groove 5 to provide rotation space for the rotating ring block 6, the rotating ring block 6 rotates with the synchronous rod 35, reducing the frictional resistance when the synchronous rod 35 rotates, and ensuring its smooth rotation.
[0029] Please see Figure 3-5 Specifically, the surfaces of the two rotating blocks 6 are fixedly connected to support frames 7, and the inside of the collection box 1 is provided with a collection compartment 8.
[0030] The above components achieve the following effects: by setting up the support frame 7 to support the synchronizing rod 35 through the rotating block 6, the stability of the synchronizing rod 35 during rotation is enhanced; the collection chamber 8 is used to store the cleaned aquatic plants, thereby realizing the centralized collection of aquatic plants.
[0031] Please see Figure 3 Specifically, a baffle 9 is slidably connected to the inner top wall of the outlet end of the collection chamber 8, and a sliding plate 10 is fixedly connected to the top of one side of the baffle 9.
[0032] The above components achieve the following effects: by setting the baffle 9 to slide and close or open the outlet end of the collection chamber 8, the water plants are prevented from falling off during the collection process; the slide plate 10 provides a force point for the movement of the baffle 9, making it easier to control the sliding of the baffle 9.
[0033] Please see Figure 3 Specifically, the bottom of the slide plate 10 is fixedly connected to the telescopic device 11, and the side wall of the outlet end of the collection chamber 8 is provided with a cavity. The bottom of the telescopic device 11 is fixedly connected to the inner bottom wall of the cavity.
[0034] The effect achieved by the above components is as follows: by setting the telescopic device 11 to extend and retract, the slide plate 10 and the baffle 9 are moved, realizing the automatic opening and closing of the outlet end of the collection chamber 8. The cavity fixes the telescopic device 11 to ensure its stability during extension and retraction, which facilitates the unloading of aquatic plants.
[0035] Please see Figure 4 Specifically, a groove 12 is provided on the other side of the baffle 9, and a slider 13 is fixedly connected to the other side wall of the outlet end of the collection chamber 8. The inner wall of the groove 12 and the surface of the slider 13 are slidably connected. A drain outlet is provided on the inner bottom wall of the collection chamber 8, and a filter screen 14 is fixedly connected to the inner wall of the drain outlet.
[0036] The effects achieved by the above components are as follows: by setting the sliding groove 12 and the slider 13 to slide together, the baffle 9 moves smoothly and prevents it from deviating and getting stuck. The filter screen 14 discharges the water in the collection chamber 8 through the water outlet, reducing the resistance when the device is dragged underwater, and at the same time preventing the water plants from being lost with the water.
[0037] Working principle: By setting up the traction component 3, the motor box 31 in the mounting cavity 2 can protect the servo motor 32. The servo motor 32 drives the push rod 33 to rotate, and the transmission belt 34 drives the synchronous rod 35 to rotate synchronously, so that the push blades 36 on the surface of the push rod 33 and the synchronous rod 35 rotate simultaneously, generating a strong propulsion force, enhancing the device's underwater propulsion power, and facilitating movement in areas with dense aquatic plants. The fixed hanging ring 37 connects to the towing steel cable 38, facilitating the movement of the external equipment towing device. The propulsion and towing work together to improve the range and efficiency of aquatic plant collection. The limiting plate 4 fits against the transmission belt 34. To prevent it from shifting and falling off during rotation, the transmission of the push rod 33 and the synchronizing rod 35 is synchronized. The rotating ring block 6 rotates in the ring groove 5, and the synchronizing rod 35 is supported by the support frame 7 to ensure stable rotation. The collection chamber 8 collects aquatic plants, and the filter screen 14 discharges water from the chamber through the drain, reducing underwater drag resistance. The telescopic device 11 extends and retracts, driving the slide plate 10 and the baffle 9 to move. The slide groove 12 and the slider 13 cooperate to ensure that the baffle 9 slides smoothly, making it easy to open the outlet end of the collection chamber 8 for unloading. This structure significantly improves the efficiency of aquatic plant cleaning and the ease of operation by strengthening the propulsion power and optimizing the transmission and drainage.
