Description

Technical Field

[0001] This invention relates to an automatic cleaning and sterilization device for the bottom of a seahorse nursery, belonging to the field of industrialized aquaculture technology. Background Technology

[0002] In industrialized aquaculture seedling breeding, pond bottom cleaning is frequently required. During the breeding process, excrement, uneaten feed, and dead organisms accumulate at the bottom of the pond. If these pollutants are not cleaned regularly, they decompose and produce harmful substances such as ammonia nitrogen and hydrogen sulfide. The accumulation of sludge at the bottom of the pond leads to water quality deterioration, often creating a breeding ground for pathogens, easily causing disease transmission, and increasing the risk of eutrophication. Traditional cleaning and sterilization work requires a large amount of manpower and involves harsh working environments. Using autonomous mobile equipment can automate these tasks, reducing labor costs and intensity.

[0003] Current automatic pool bottom cleaning devices have the following shortcomings:

[0004] 1. The cleaning and maintenance of existing automatic pool bottom cleaning devices are cumbersome and not very convenient to use.

[0005] 2. In the existing technology, the bottom suction port of the automatic pool bottom cleaning device is usually a round or square hole, which is prone to clogging. Moreover, it cannot absorb the pool bottom dirt brushed off by the cleaning roller in time during the process, resulting in a long suction time and low efficiency.

[0006] 3. The existing automatic pool bottom cleaning device is not compact in its structural design and the arrangement of functional components is not very reasonable;

[0007] 4. The existing automatic pond bottom cleaning device has low functional complexity, lacks sterilization function and underwater fish fry observation function; and the positioning and navigation mainly rely on the ultrasonic probe installed on one side of the device for distance measurement and positioning, and the path planning is based on collision avoidance strategy. Its positioning is easily affected by the environment inside the aquaculture pond, which leads to reduced accuracy and affects the mobile cleaning effect.

[0008] 5. In the existing technology, the impeller assembly of the automatic cleaning device at the bottom of the pond usually rotates at a high speed, which causes a lot of disturbance to the water and underwater noise. Since seahorse fry have poor swimming ability, their health is easily affected by the external environment. The device can easily cause stress to the fry in the nursery pond or even cause a large number of deaths. In short, it cannot be directly applied to the bottom cleaning and sterilization of seahorse nursery ponds. Summary of the Invention

[0009] The purpose of this invention is to provide an automatic cleaning and sterilization device for the bottom of seahorse breeding ponds, thereby solving the above-mentioned technical problems.

[0019] Furthermore, the impeller base 701 is threadedly connected to the impeller fixing platform 807, and an impeller cover 702 is fixedly installed on the upper side of the impeller base 701. A fixing bracket 704 is provided on the inner side of the impeller cover 702, and an impeller 704 is fixedly connected to one end of the fixing bracket 704.

[0020] Preferably, the automatic cleaning and sterilization device for the bottom of the pool is 25-50cm in length, 15-35cm in width, and weighs 1-2.5kg.

[0021] The beneficial effects of this invention are as follows:

[0022] 1) A cleverly designed pull-out filter screen divides the internal space enclosed by the top cover and bottom shell into two parts: the front part is used to store dirt, and the rear part is used to store functional components, making cleaning and maintenance convenient and efficient. Moreover, a concave card plate is fixedly connected to the lower side of the inner surface of the bottom shell, a pull-out handle is fixedly installed on the top of the pull-out filter screen, a brush plate is fixedly installed below the pull-out handle, a filter screen is fixedly installed on the inner surface of the brush plate, and a filter screen frame is fixedly installed on the outer side of the filter screen. The lower side of the filter screen frame is slidably connected to the concave card plate and the top cover. When the filter screen needs to be cleaned, simply pull the filter screen frame upwards by pulling the handle for manual rinsing, making the cleaning and maintenance of the filter screen more convenient and efficient.

[0023] 2) The bottom suction port of the automatic cleaning device is designed as a V-shaped water inlet with the same horizontal width as the cleaning roller. The pointed end of the V-shaped water inlet leads forward. As the automatic cleaning and sterilization device moves forward, the dirt brushed off by the cleaning roller is gradually absorbed from the middle to both sides and then drawn into the interior of the device. Compared with the existing technology where the suction port is usually a round or square hole, the cleaning effect is significantly improved, and it is less prone to clogging. The time required for suction is shortened and the efficiency is improved.

[0024] 3) The design of the sealed control chamber is highly complex, making the entire automatic cleaning device at the bottom of the pool more compact and rational in structure;

[0025] 4) By fixing an underwater depth camera to the front of the bottom shell, threading a sealed control chamber to the lower inner surface of the bottom shell, installing transmission units on both sides of the bottom shell, fixing a cleaning roller to one end of the transmission unit, and fixing an ultraviolet sterilization module to the rear of the bottom shell, the device can add ultraviolet sterilization function to the cleaning and suction function, and is equipped with an underwater fish fry status recognition function. The underwater fish fry recognition data can be transmitted to a remote terminal through the Lora module in the main control board, with a transmission depth of up to 7 meters, so that users can observe the health status of the fish fry and the impact of the cleaning device on the fish fry in real time.

[0026] 5) By threading a sealing chamber top seat onto the upper side of the sealing chamber base, a main control unit is fixedly connected to the inner surface of the sealing chamber base, and dynamic sealing units are fixedly installed on both sides of the lower end of the sealing chamber base. The dynamic sealing units are rotatably connected to brushless DC motors, and a waterproof battery is fixedly connected to the lower end of the inner surface of the bottom shell. High-range ultrasonic sensors are fixedly installed around the bottom shell. The high-range ultrasonic sensors, brushless DC motors, and waterproof batteries are all connected to the main control unit via wires, and the wires are fixedly connected to the sealing chamber base via waterproof connectors. This allows the device to detect the distance to the seedling pond in real time through four high-range ultrasonic sensors fixedly installed on the outer surface, perform four-way distance measurement and positioning, and path planning, thereby improving the positioning and navigation accuracy of the automatic cleaning device for the seedling pond.

[0027] 6) By fixing a V-shaped water inlet trough to the lower side of the bottom shell, threading a cover to the upper side of the bottom shell, fixing two low-speed impeller units to the upper side of the sealed control chamber, setting a filter screen in the center of the device, and fixing a cleaning roller to one end of the transmission unit, the bottom cleaning device of the seedling pond can generate negative pressure adsorption force through the rotation of two sets of low-speed impellers. The bottom sludge flows through the V-shaped water inlet trough and is filtered by a pull-out filter screen. Under the premise of ensuring the adsorption force, two sets of low-speed impellers replace a single high-speed impeller, which reduces the disturbance to the water in the seedling pond, noise and stress to the seedlings during sludge suction.

[0046] Transmission unit 9:

[0047] like Figure 7 and Figure 8 As shown, the motor shaft connecting platform 901 is fixedly connected to the rotating shaft of the brushless DC motor 803.

[0048] Low-speed impeller unit 7:

[0049] like Figure 9 As shown, the impeller base 701 is threadedly connected to the impeller fixing platform 807. An impeller cover 702 is fixedly installed on the upper side of the impeller base 701. A fixing bracket 704 is provided on the inner side of the impeller cover 702. One end of the fixing bracket 704 is fixedly connected to the impeller 704.

[0050] Explanation of the principle:

[0051] 1. By fixing an inlet unit at the bottom of the treatment tank, fixing a support base at the bottom of the treatment tank, fixing an outlet pipe on the upper side of the outer surface of the treatment tank, fixing a filter unit on the lower inner surface of the treatment tank, evenly arranging several filter screens around the filter unit, and setting several aeration devices on the lower surface of the treatment tank, the device can filter the pollutants flowing into the treatment tank.

[0052] 2. A flow channel heater is fixedly connected to the outside of the inlet pipe so that the discharged water flowing into the treatment tank can be heated, thereby improving the treatment efficiency of sludge dissolution and fermentation.

[0053] 3. The filtration unit separates the wastewater containing pollutants in the treatment tank into a wastewater zone and a clean water zone. This allows the filtered pollutants to settle in the wastewater zone for fermentation, and continuous aeration enhances the efficiency of sedimentation and fermentation. Several screen sedimentation partition plates are fixedly connected from top to bottom on the outer surface of the screen support, and several tank sedimentation partition plates are fixedly connected from top to bottom on the inner surface of the treatment tank body. This increases the distance the wastewater from the clean water zone reaches the outlet, improving the sedimentation and fermentation treatment effect. Therefore, this device can efficiently filter particulate matter in the wastewater, preventing the accumulation of pollutants in the aquaponics system and avoiding the negative impact of over-eutrophication on the growth of aquaculture organisms.

[0054] 4. A screen cleaning roller is rotatably connected to the outside of the brush plate fixing frame, and a water inlet support is rotatably connected to the lower end of the base shaft. A motor fixing seat is fixedly connected to the inner surface of the treatment tank body, and a cleaning motor is fixedly installed on the upper side of the motor fixing seat. The cleaning motor is fixedly connected to the cleaning filter unit through a coupling, so that the device can drive the cleaning filter unit through the cleaning power module to automatically and continuously clean the filter screen in the sewage area, preventing the filter screen from being blocked due to dirt accumulation. The whole process requires no manual intervention, reducing the intensity of manual labor.

[0055] This invention ingeniously designs a pull-out filter screen, dividing the internal space enclosed by the top cover and bottom shell into two parts: the front part for storing waste and the rear part for storing functional components, making cleaning and maintenance convenient and efficient. Furthermore, a concave retaining plate is fixedly connected to the lower side of the inner surface of the bottom shell, a pull-out handle is fixedly installed on the top of the pull-out filter screen, a brush plate is fixedly installed below the pull-out handle, a filter screen is fixedly installed on the inner surface of the brush plate, and a filter screen frame is fixedly installed on the outer side of the filter screen. The lower side of the filter screen frame is slidably connected to the concave retaining plate and the top cover. When cleaning the filter screen is required, simply pull the filter screen frame upwards using the pull-out handle for manual rinsing, making cleaning and maintenance of the filter screen convenient and efficient. The automatic cleaning device for the pool bottom is designed with a V-shaped water inlet, equal in width to the cleaning rollers, making cleaning more convenient and efficient. The pointed end of the V-shaped inlet leads forward, allowing dirt brushed off by the cleaning rollers to be gradually absorbed from the center outwards as the device moves forward. This significantly improves cleaning efficiency compared to existing technologies with typically round or square suction ports, reduces clogging, shortens suction time, and increases efficiency. The sealed control chamber is a multifunctional component, making the entire automatic cleaning device more compact and rationally designed. (The last sentence appears to be incomplete and possibly refers to a different design element.) An underwater depth camera is fixedly mounted on the front side of the device. A sealed control chamber is threadedly connected to the lower inner surface of the bottom shell. Transmission units are installed on both sides of the bottom shell, with cleaning rollers fixedly connected to one end of each transmission unit. An ultraviolet sterilization module is fixedly mounted on the rear side of the bottom shell. This allows the device to add ultraviolet sterilization functionality to its cleaning and suction capabilities. It also features underwater fish fry status recognition; underwater fish fry recognition data can be transmitted to a remote terminal via the Lora module in the main control board, with a transmission depth of up to 7 meters. This allows users to observe the health status of the fish fry and the impact of the cleaning device on them in real time. A sealed top seat is threadedly connected to the upper side of the sealed chamber base, and a control chamber is located on the inner side of the sealed chamber base. The main control unit is fixedly connected to the surface. Dynamic sealing units are fixedly installed on both sides of the lower end of the sealed chamber base. The dynamic sealing units are rotatably connected to the brushless DC motors. A waterproof battery is fixedly connected to the lower end of the inner surface of the bottom shell. High-range ultrasonic sensors are fixedly installed around the bottom shell. The high-range ultrasonic sensors, brushless DC motors, and waterproof batteries are all connected to the main control unit through wires. The wires are fixedly connected to the sealed chamber base through waterproof connectors. This allows the device to detect the distance to the seedling pond in real time through four high-range ultrasonic sensors fixedly installed on the outer surface, and perform four-way distance measurement and positioning and path planning, thereby improving the positioning and navigation accuracy of the automatic cleaning device for the seedling pond.By fixing a V-shaped water inlet trough to the lower side of the bottom shell, threading a cover to the upper side of the bottom shell, and fixing two low-speed impeller units to the upper side of the sealed control chamber, a filter screen is installed at the center of the device, and a cleaning roller is fixedly connected to one end of the transmission unit, the bottom cleaning device of the seedling pond generates negative pressure suction force through the rotation of the two sets of low-speed impellers. The sludge at the bottom of the pond flows through the V-shaped water inlet trough and is filtered by a pull-out filter screen. While ensuring suction force, using two sets of low-speed impellers instead of a single high-speed impeller reduces disturbance to the water in the seedling pond, noise, and stress on the seedlings during suction.

[0056] The above are preferred embodiments of the present invention. Those skilled in the art can make their own modifications or improvements based on this, and such modifications or improvements should fall within the scope of protection claimed by the present invention without departing from the overall concept of the present invention.
