Description

Technical Field

[0001] This invention belongs to the field of water surface cleaning machines, and specifically relates to a water surface cleaning robot. Background Technology

[0002] With the gradual improvement of modern living standards, people have begun to pay more attention to the environment, with particular concern being the large amount of floating garbage on the water surface. This garbage not only pollutes the water quality but also easily breeds mosquitoes and spreads diseases. To clean up the garbage on the water surface and avoid damage to the environment, manual retrieval is usually used, but the retrieval efficiency is low. Therefore, existing technology provides a water surface cleaning device for collecting floating garbage on the water surface. After the cleaning device collects the garbage on the water surface, the collection component located inside the water surface cleaning device is removed, and the garbage inside the collection component is emptied, thereby completing the garbage recycling. However, due to the influence of the complex water surface environment, the fluctuation of the water surface can cause some floating objects located at the water inlet of the water surface cleaning device to float out, thus affecting the cleaning effect of the water surface. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a water surface cleaning robot. The technical problem this invention aims to solve is: how to improve the efficiency of waste recycling.

[0004] The objective of this invention can be achieved through the following technical solution: A water surface cleaning robot includes a body, on which a through groove is provided. A receiving component located at the front end of the through groove and two symmetrically arranged drive motors are provided in the through groove. Both drive motors are fixedly connected to the side walls of the through groove or to the bottom of the through groove. The characteristic is that a guide plate is provided under the drive motor located at the rear end of the through groove. The guide plate, the receiving component, and the through groove cooperate to form a cavity that runs through the front and rear. The rear end of the guide plate is connected to the body through a partition located between the two drive motors. The two drive motors are respectively located in a flow channel formed by the partition, the guide plate, and the through groove wall.

[0005] This application mainly involves setting a downward-facing through-channel at the bottom of the machine body, extending from the front end to the rear end of the machine body to facilitate water entering from the front end and exiting from the rear end. A drive motor located at the rear end of the through-channel drives the machine body forward, causing waste to enter the collection component located at the front end of the through-channel. This collection component works in conjunction with a roller brush located at the water inlet at the front end of the machine body to guide the waste floating on the water surface into the collection component. A guide plate is installed below the drive motor and is fixed to the machine body, thus forming a cavity that is only open from front to back. The guide plate, the side wall of the through-channel, and the partition plate form a flow channel. Since the water enters from the front end, after the waste is filtered out by the collection component, it enters the cavity surrounded by the guide plate. Under the action of the drive motor, the volume discharged is reduced due to the presence of the flow channel, thus increasing the water flow rate discharged by the drive motor. This creates a certain negative pressure inside the collection component and at the front end, fixing the waste in the collection component and preventing small pieces of waste from floating out due to water flow interference, thereby improving the efficiency of waste recycling.

[0006] In the aforementioned water surface cleaning robot, each of the drive motors is equipped with an impeller, which is located inside a straight pipe in the flow channel. The impeller is mounted on the drive motor and rotates through it, providing power for the robot's forward movement. The impeller is completely housed within a cavity that is only open from front to back, ensuring pressure at the collection component and the robot's water inlet, thereby improving waste collection efficiency. Furthermore, the straight pipe in the flow channel...

[0007] In the aforementioned water surface cleaning robot, an electronic control component is located between the storage component and the drive motor, and a guide plate covers both the electronic control component and the drive motor. By placing both the electronic control component and the drive motor inside the guide plate, contact between the electronic control component and the drive motor and the bottom is avoided, while also preventing ribbon-like debris in the water from entangled with the electronic control component, thus improving its stability.

[0008] In the aforementioned water surface cleaning robot, the storage component is located at the front end of the robot body, and the storage component, electronic control components, and drive motor are sequentially arranged in a through-channel from front to back. Water enters through the storage component, is filtered, passes through the electronic control components, and is discharged by the drive motor.

[0009] In the aforementioned water surface cleaning robot, an electronic control component is provided between the storage component and the drive motor, and there is a gap between the electronic control component and the two side walls of the through groove.

[0010] In the aforementioned water surface cleaning robot, when the drive motor moves the robot body forward, the sidewall of the through-channel and the front end of the receiving component cooperate to form a negative pressure zone. The forward movement of the robot body by the drive motor, in conjunction with the flow channel, accelerates the water flow within the channel, thereby creating the negative pressure zone.

[0011] In the aforementioned water surface cleaning robot, the two side walls at the front end of the through-channel are symmetrically arranged guide slopes. The negative pressure zone includes a water inlet formed by the guide slopes and the front end of the receiving component, as well as the inner cavity of the receiving component. By setting guide slopes at the front end of the through-channel, the resistance during the movement of the robot is reduced while the area of ​​the water inlet is increased, further improving the collection efficiency.

[0012] In the aforementioned water surface cleaning robot, the storage component is inserted into the through slot from the front of the robot body, and the front of the storage component is equipped with a handle for easy retrieval. By providing a handle at the front of the storage component, it is convenient to remove the storage component from the front.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This application mainly involves arranging a collection component, an electrical control component, and a drive motor from front to back within a through-channel. A guide plate is then placed below the drive motor and the electrical control component, forming a through-channel cavity between the guide plate and the channel wall. Two symmetrically placed drive plates are separated by a partition, which, together with the guide plate and the through-channel, forms a flow channel. By reducing the drainage area, the water flow velocity is further increased while maintaining the same flow rate. This creates a negative pressure zone at the front end of the through-channel and the collection component, reducing the impact of water flow fluctuations on waste recycling and preventing smaller pieces of waste from flowing out of the collection component, thereby improving waste collection efficiency.

[0015] 2. The two side walls at the front end of the through channel are provided with guide slopes, which, together with the collection components, form a trapezoidal water inlet. This not only increases the garbage collection range but also further increases the coverage area of ​​the negative pressure zone, thereby improving garbage collection efficiency.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 and Figure 2 As shown, this application discloses a water surface cleaning robot. Within a through-channel 1a, a storage component 2, an electronic control assembly 5, and a drive motor 3 are sequentially arranged along the robot's movement direction. There are two drive motors 3, with two impellers 3a arranged symmetrically rearward. Below the electronic control assembly 5 and the two drive motors 3, guide plates 4a are fixed to both sides of the through-channel 1a and cooperate with the walls of the through-channel 1a to form a cavity. The rear end of the guide plates 4a is connected to the robot body 1 via a partition 4b located between the two drive motors 3. The partition 4b, the walls of the through-channel 1a, and the guide plates 4a cooperate to form a water supply and discharge channel 4c. A straight pipe 4c1 is provided on a section of the channel 4c that connects to the outside. The drive motors 3 and impellers 3a are both located within the channel 4c. Guide slopes are provided on both sides of the water inlet at the front end of the through-channel 1a, and a handle 2a is provided at the front end of the storage component 2.

[0023] like Figure 3 and Figure 4 As shown, the housing 2, the electronic control component 5, and the drive motor 3 are arranged sequentially along the length of the body 1 from the front end of the through groove 1a. The electronic control component 5 is located between the housing 2 and the drive motor 3, and both the electronic control component 5 and the drive motor 3 are encased in the cavity formed by the guide plate 4a and the through groove 1a. The guide plate 4a is fitted with the rear wall of the housing 2, and the rear end of the body 1 is provided with a flow channel 4c that can discharge water, thus making the cavity open from front to back. A straight pipe 4c1 is provided on the flow channel 4c, and the impeller 3a on the drive motor 3 is located directly above the straight pipe 4c1. The front ends of the two side walls of the through groove 1a are symmetrically provided with two guide slopes 1a1, which are fitted with the front end of the housing 2 to form a trapezoidal water inlet 6a, and the water inlet 6a and the inner cavity 6b of the housing 6a form a negative pressure zone 6.

[0024] The main working principle of this application is that when the water surface cleaning robot is working in a swimming pool, pond or other place where water surface garbage needs to be treated, the drive motor 3 drives the impeller 3a to move the drive motor body 1 forward. The garbage on the water surface is gathered together by the guide slope at the front end of the through groove 1a and the water inlet 6a formed by the collection component 2. The water flow is stirred by the roller brush on the body 1, so that the garbage floating on the water surface enters the collection component 2. After being filtered by the collection component 2, it is discharged back into the pool through the rear wall of the collection component 2.

[0025] To prevent ripples on the water surface from entering the inlet 6a during the water surface cleaning robot's operation, and to prevent small floating debris from flowing back into the pool through the inlet 6a, a guide plate 4a is installed below the drive motor 3 (which moves the drive unit 1) and the electronic control components 5. The front end of the guide plate 4a engages with the receiving component 2, and the rear end of the guide plate 4a has a flow channel 4c that can accommodate the drive motor 3. This allows the guide plate 4a and the through groove 1a to form a through cavity, which is then cleaned by the flow channel 1a. After filtration, the water enters the cavity through the rear wall of the receiving component 2 and is discharged through the flow channel 4c. Since the flow channel 4c is formed by the cooperation of the through groove 1a wall, the guide plate 4a and the baffle 4b, and the drive motor 3 is set in the flow channel 4c, the discharge speed is increased by reducing the discharge area under the same flow rate. This makes the inner cavity 6b of the receiving component 2 and the water inlet 6a of the machine body 1 form a low-pressure zone, so that small garbage can be fixed in the receiving component 2 and prevented from escaping into the water tank, thereby improving the garbage recycling efficiency.

[0026] Furthermore, by placing the electronic control component 5 between the storage component 2 and the drive component, and setting it together with the drive component in the cavity formed by the guide plate 4a and the wall of the through channel 1a, the equipment is simplified and the space utilization of the equipment is improved. At the same time, by increasing the area of ​​the cavity, the flow rate of the water is increased, and then further increased by the impeller 3a. By forming a negative pressure zone 6 in the through channel 1a, smaller floating objects are prevented from returning to the pool, thus improving the efficiency of waste recycling.

[0027] Based on this, the drive motor 3 is arranged symmetrically around the partition 4b, and a straight pipe 4c1 is set at the rear end of the flow channel 4c. The impeller 3a on the drive motor 3 is positioned directly above the straight pipe 4c1, parallel to the axis of the impeller 3a. This prevents the outward tilt of the drainage end of the flow channel 4c from affecting the posture of the water surface cleaning robot, ensuring the normal operation of the water surface cleaning equipment. Furthermore, by symmetrically placing guide ramps 1a1 at the front end of the through groove 1a, and having them cooperate with the collection component 2 to form a water inlet 6a, the range of waste that can be collected by the water surface cleaning equipment is increased. The collection component 2 is equipped with a handle 2a at its front end, allowing the collection component 2 to be removed from the front.
