Description

Technical Field

[0001] This invention relates to the technical field of water collection tanks, and more particularly to a water collection tank cleaning device. Background Technology

[0002] Currently, open-type collection tanks are commonly used in water purification for liquid collection and diversion. However, due to long-term operation, algae and sediment easily accumulate on the inner bottom, inner sides, and outer walls of these tanks. If not cleaned promptly, this not only reduces the cross-sectional area for water flow and lowers transport efficiency but also promotes bacterial growth and water contamination. Existing systems often consist of multiple continuous collection tanks, with several crossbars typically used for support between adjacent tanks. When traditional cleaning trolleys cross these crossbars, the brushes on their outer sides are easily jammed or damaged, leading to equipment downtime or even complete failure. Summary of the Invention

[0003] To address the above shortcomings, this invention proposes a water collection tank cleaning device that uses different brushes to thoroughly clean the water collection tank and utilizes the cooperation of a third brush and a gravity mechanism to achieve rotational obstacle avoidance, reducing cleaning dead angles in the water collection tank. The device has a simple and reliable structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A water collection tank cleaning device includes: a mobile trolley, a first brush disposed at the bottom of the mobile trolley for abutting against the inner bottom wall of the water collection tank, a second brush disposed on the side of the mobile trolley for abutting against the inner side wall of the water collection tank, a third brush rotatably disposed on the side of the mobile trolley for abutting against the outer side wall of the water collection tank, and a gravity mechanism disposed between the third brush and the mobile trolley. When the third brush rotates past the crossbar between the two water collection tanks, the gravity mechanism drives the third brush to rotate to a vertical position.

[0005] Furthermore, the mobile trolley is equipped with a stand, and the stand is horizontally equipped with a mounting rod. The two ends of the mounting rod are equipped with mounting plates, and the lower end of the mounting plate is rotatably equipped with a mounting block. The mounting block is equipped with two first guide rods along the same straight line. The gravity mechanism is a gravity block slidably mounted on the first guide rod. Each first guide rod is symmetrically equipped with an auxiliary rod at an acute angle on both sides. The third brush is connected to the mounting block, and the auxiliary rod is used to abut against the crossbar to drive the third brush to rotate.

[0006] Furthermore, the third brush includes a mounting frame, and a groove is provided on the side of the mounting frame facing away from the first guide rod. The gravity block slides in cooperation with the groove, and a first nut is threadedly connected to the side of each first guide rod away from the mounting block.

[0007] Furthermore, a first magnetic block is provided at one end of the mounting plate near the mounting block, and the gravity block is a second magnetic block. The second magnetic block moves down to magnetically engage with the first magnetic block to lock the third brush in a vertical position.

[0008] Furthermore, the third brush also includes a brush body that slides with the mounting frame. The mounting frame has stepped holes at both ends, and the mounting frame is correspondingly provided with a first threaded rod with one end passing through the stepped hole. The other end of the first threaded rod passes through the brush body. The two ends of the first threaded rod are threadedly connected with second nuts, one of which abuts against the mounting frame and the other of which abuts against the brush body. The first threaded rod is movably sleeved with a first spring, which is located between the brush body and the stepped surface of the stepped hole.

[0009] Furthermore, the mounting rod has threaded sections at both ends, and two third nuts are provided opposite to each threaded section. The mounting plate is clamped between the two third nuts. The upright is provided with a second guide rod parallel to the mounting rod, and the mounting plate is provided with a guide hole that cooperates with the second guide rod.

[0010] Furthermore, the mobile trolley includes a rectangular base frame, inside which a support rod is provided. The first brush is mounted on the support rod via a second threaded rod. A second spring is provided between the first brush and the support rod. One end of the second threaded rod is threadedly connected to a first limiting nut, which abuts against the support rod.

[0011] Furthermore, a first upright is provided at each of the four corners of the base frame, and two horizontal bars are provided at vertical intervals between two adjacent first uprights. The second brush is installed on the horizontal bars through a third threaded rod. A third spring is provided between the second brush and the third threaded rod. A second limiting nut is threaded to one end of the third threaded rod, and the second limiting nut abuts against the horizontal bar.

[0012] Furthermore, a rectangular frame is provided at the upper end of each of the four first uprights, and the frame includes two opposing second uprights, one end of which is connected to the rectangular frame and the other end of which is connected to the mounting rod.

[0013] Furthermore, each of the four corners of the base frame is provided with a movable gear, the base frame is provided with a drive motor, the output end of the drive motor is connected to a transmission mechanism, the output end of the transmission mechanism is connected to two drive gears, and each drive gear meshes with the corresponding movable gear.

[0014] Compared with existing technologies, the present invention has at least the following beneficial effects: 1. In this invention, the combination of the first brush, the second brush and the third brush achieves full coverage cleaning of the bottom wall, inner side wall and outer side wall of the water collection tank.

[0015] 2. This invention, through the reset function of the third brush combined with the gravity mechanism, enables the device to autonomously cross the crossbars between adjacent water collection tanks. This not only ensures that the third brush stably returns to the vertical position after overcoming the obstacle, maintaining a tight fit with the outer wall and avoiding missed brushing, but also improves the reliability of continuous operation without manual intervention. The structure is simple, the cost is low, and it is suitable for cleaning scenarios where there are periodic obstacles in the water collection tank. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] See Figures 1 to 4 A water collection tank cleaning device includes: a mobile trolley 100, a first brush 110 disposed at the bottom of the mobile trolley 100 for abutting against the inner bottom wall of the water collection tank, a second brush 120 disposed on the side of the mobile trolley 100 for abutting against the inner side wall of the water collection tank, a third brush 130 rotatably disposed on the side of the mobile trolley 100 for abutting against the outer side wall of the water collection tank, and a gravity mechanism disposed between the third brush 130 and the mobile trolley 100. When the third brush 130 rotates past the crossbar between the two water collection tanks, the gravity mechanism drives the third brush 130 to rotate to a vertical position.

[0023] In the above-described water collection tank cleaning device, the mobile trolley 100 moves along the length of the water collection tank as a carrier. The first brush 110 always abuts against the inner bottom wall of the water collection tank, the second brush 120 abuts against the inner side wall of the water collection tank, and the third brush 130 abuts against the outer side wall of the water collection tank, thereby achieving comprehensive brushing of the inner bottom wall, inner side wall, and outer side wall of the water collection tank. When the mobile trolley 100 travels to the crossbar between two adjacent water collection tanks, the third brush 130 is blocked by the crossbar and rotates counterclockwise to overcome the obstacle. After the third brush 130 overcomes the obstacle, the gravity mechanism uses its own weight to drive the third brush 130 to continue rotating to a vertical position, allowing the third brush 130 to autonomously cross the crossbar between adjacent water collection tanks without manual intervention. This facilitates the third brush 130 to re-adhere to the outer side wall of the water collection tank, ensuring continuous brushing of the outer side wall and improving the reliability of continuous operation.

[0024] See Figures 1 to 4Furthermore, the mobile trolley 100 is provided with a stand 140, and the stand 140 is horizontally provided with a mounting rod 141. The two ends of the mounting rod 141 are provided with mounting plates 142. The lower end of the mounting plate 142 is rotatably provided with a mounting block 150. The mounting block 150 is provided with two first guide rods 151 along the same straight line. The gravity mechanism is a gravity block 152 that is slidably provided on the first guide rod 151. Each first guide rod 151 is provided with an auxiliary rod 153 symmetrically arranged at an acute angle on both sides. The third brush 130 is connected to the mounting block 150. The auxiliary rod 153 is used to abut against the crossbar to drive the third brush 130 to rotate. Specifically, when the moving trolley 100 moves to the crossbar, the auxiliary rod 153 is blocked by the crossbar and rotates, thereby causing the third brush 130 to rotate. This causes the lower section of the third brush 130 to rotate counterclockwise to the upper part of the mounting block 150. After the auxiliary rod 153 passes the crossbar, the two gravity blocks 152 slide downward along the corresponding first guide rod 151. By the center of gravity falling back, the third brush 130 is rotated counterclockwise to the vertical position. No external drive mechanism is required, the overall structure is simple and low cost. Gravity is used to ensure that the third brush 130 stably returns to the vertical position after overcoming the obstacle, which helps to maintain the close contact between the third brush 130 and the outer wall and avoid missed brushing. With the above structure, the third brush 130 rotates 180 degrees counterclockwise using the auxiliary rod 153 and the gravity block 152. This not only eliminates the need for an external drive mechanism, reducing the overall weight of the device and thus reducing the power load on the moving trolley 100, but also allows the third brush 130 to perform rotational brushing relative to the crossbar, eliminating the need for the third brush 130 to be dragged over the crossbar to overcome obstacles, thereby reducing blind spots in the brushing of the outer wall of the water collection tank. It is understood that the lower end of the mounting plate 142 is higher than the crossbar, and both its lower end and the mounting block 150 have mounting holes. Pivots are inserted through the two mounting holes, and threads are provided at both ends of the pivots to prevent the mounting block 150 from falling off via mounting nuts. Furthermore, the first guide rod 151 is a smooth rod welded to the upper and lower surfaces of the mounting block 150, and the gravity block 152 can be a cast iron block with a through hole in the middle, with the through hole fitting with the first guide rod 151. The auxiliary rod 153 is an inclined smooth rod, symmetrically welded to both sides of the mounting block 150. The angle between the axis of the auxiliary rod 153 and the horizontal direction is set to 30° to 60° to ensure that sufficient rotational force can be generated when the crossbar contacts.

[0025] See Figures 1 to 4Furthermore, the third brush 130 includes a mounting frame 131. A groove 132 is provided on the side of the mounting frame 131 facing away from the first guide rod 151. The gravity block 152 slides within the groove 132. A first nut 154 is threaded onto the side of each first guide rod 151 furthest from the mounting block 150. Specifically, the sliding engagement between the groove 132 and the gravity block 152 allows the gravity block 152 to translate along the groove 132, ensuring that the gravity block 152 always moves within a preset path. The first nut 154 prevents the gravity block 152 from detaching from the first guide rod 151, avoiding detachment due to obstacle crossing impacts.

[0026] See Figures 1 to 3 Furthermore, a first magnetic block 143 is provided at one end of the mounting plate 142 near the mounting block 150, and a gravity block 152 serves as a second magnetic block. The second magnetic block moves down to magnetically engage with the first magnetic block 143, thereby locking the third brush 130 in a vertical position. Specifically, when the third brush 130 rotates past the crossbar and returns to the vertical position, the gravity block 152 moves down to contact the first magnetic block 143. The two magnetically engage to generate an adsorption force, thereby locking the third brush 130 in a vertical position. This prevents the third brush 130 from accidentally deflecting due to vibrations during device movement, ensuring that the third brush 130 continuously and stably abuts against the outer wall of the water collection tank. The magnetic engagement is free of mechanical jamming; unlocking only requires overcoming the magnetic force to rotate, without affecting the flexibility of obstacle crossing. Moreover, the structure is simple, requires no additional power source, is low-cost, and easy to maintain, making it suitable for cleaning scenarios where the water collection tank requires periodic obstacle crossing operations.

[0027] See Figures 3 to 4 Furthermore, the third brush 130 also includes a brush body 133 that slides with the mounting frame 131. The mounting frame 131 has stepped holes 134 at both ends. The mounting frame 131 is correspondingly provided with a first threaded rod 135 with one end passing through the stepped hole 134. The other end of the first threaded rod 135 passes through the brush body 133. The two ends of the first threaded rod 135 are threadedly connected with second nuts 136. One second nut 136 abuts against the mounting frame 131, and the other second nut 136 abuts against the brush body 133. The first threaded rod 135 is movably sleeved with a first spring 137, which is located between the brush body 133 and the stepped surface of the stepped hole 134. Specifically, by adjusting the position of the second nut 136 on the threaded rod, the compression deformation of the first spring 137 can be adjusted, thereby using the spring force to push the brush body 133 outward against the outer wall of the water collection tank. This not only makes it easier to maintain the contact pressure between the brush body 133 and the outer wall, improving the cleaning effect and the service life of the brush, but also facilitates the subsequent replacement of the third brush 130.

[0028] See Figures 1 to 3Furthermore, the mounting rod 141 has threaded sections at both ends, with two third nuts 144 positioned opposite each threaded section. The mounting plate 142 is clamped between the two third nuts 144. The support frame 140 has a second guide rod 145 parallel to the mounting rod 141, and the mounting plate 142 has a guide hole that mates with the second guide rod 145. Specifically, the mounting plate 142 is fixed horizontally by being clamped by the two third nuts 144. The second guide rod 145 slides with the mounting rod 141, providing horizontal guidance and constraint for the mounting plate 142, preventing the mounting plate 142 from rotating around the mounting rod 141, ensuring the stability of the third brush 130 in the vertical plane during travel and obstacle crossing, and preventing the third brush 130 from tilting due to lateral forces. It can be understood that the lower part of the second guide rod 145 is flat, and the lower sidewall of the guide hole contacts the plane of the second guide rod 145, thereby restricting the rotation of the mounting plate 142.

[0029] See Figures 1 to 3 Furthermore, the mobile trolley 100 includes a rectangular base frame 101. A support rod 102 is installed inside the base frame 101. A first brush 110 is mounted on the support rod 102 via a second threaded rod 103. A second spring 104 is provided between the first brush 110 and the support rod 102. One end of the second threaded rod 103 is threadedly connected to a first limiting nut, which abuts against the support rod 102. Specifically, the elastic compression of the second spring 104 allows the first brush 110 to adapt to the unevenness of the bottom wall of the water collection tank, preventing damage to the bristles due to hard contact. Changing the position of the first limiting nut on the second threaded rod 103 adjusts the deformation of the second spring 104, which helps adjust the brushing pressure according to the intensity of stain adhesion, improving cleaning efficiency. The base frame 101 is a frame welded from rectangular steel pipes, with one or more transverse support rods 102 welded inside to provide mounting positions for the first brush 110, reducing the overall weight.

[0030] See Figures 1 to 3Furthermore, each of the four corners of the base frame 101 is provided with a first upright post 105, and two horizontal posts 106 are arranged vertically between two adjacent first upright posts 105. The second brush 120 is installed on the horizontal posts 106 via a third threaded rod 107. A third spring 108 is provided between the second brush 120 and the third threaded rod 107. One end of the third threaded rod 107 is threadedly connected to a second limiting nut, which abuts against the horizontal post 106. Specifically, through the position adjustment of the second limiting nut and the elastic compensation function of the third spring 108, not only can the second brush 120 be adapted to water collection tanks of different widths, but also by adjusting the extension length of the second brushes 120 on both sides, symmetrical pressure on the inner wall is ensured, so that the second brush 120 can adapt to the uneven surface of the inner wall of the water collection tank, ensuring the fit of the second brush 120 and preventing the moving trolley 100 from deviating. The upper and lower double horizontal bars 106 are used to install double rows of second brushes 120, which expands the cleaning coverage of the inner wall and improves cleaning efficiency. In addition, the frame design of the first upright bar 105 and the horizontal bars 106 provides a stable installation foundation for the second brushes 120.

[0031] See Figures 1 to 3 Furthermore, rectangular frames 109 are provided at the upper ends of the four first uprights 105. The frame 140 includes two opposing second uprights 146, one end of which is connected to the rectangular frame 109, and the other end of which is connected to the mounting rod 141. Specifically, the rectangular frame 109 and the second uprights 146 are welded together, which helps to construct a high-strength and stable frame 140, effectively resisting the impact force when the third brush 130 crosses obstacles and the vibration during movement, and preventing deformation of the frame 140. The frame structure formed by the bottom frame 101, the first uprights 105, and the rectangular frames 109 simplifies the structure of the mobile trolley 100, thereby reducing the output load of the mobile trolley 100.

[0032] See Figures 1 to 3Furthermore, each of the four corners of the base frame 101 is equipped with a movable gear 160, and the base frame 101 is equipped with a drive motor 161. The output end of the drive motor 161 is connected to a transmission mechanism, and the output end of the transmission mechanism is connected to two drive gears 162. Each drive gear 162 meshes with a corresponding movable gear 160. Specifically, the output end of the drive motor 161 is connected to a first bevel gear, and second bevel gears mesh with both sides of the first bevel gear. The second bevel gears are connected to the drive gears 162 via shafts, thereby transmitting power to the two drive gears 162 through the bevel gear assembly. This causes the drive gears 162 to mesh with the movable gears 160 on the same side, thereby driving the movable gears 160 to rotate, ultimately achieving automatic movement of the mobile trolley 100. This reduces the intensity of manual operation and is suitable for continuous cleaning of long-distance water collection tanks. It is understood that the drive motor 161 is connected to an external power supply device via a wire, and the wire can be wound up and unwound using a retractor to adapt to the travel distance of the mobile trolley. In some embodiments, the drive motor 161 is connected to an external controller via a through-wire, which facilitates forward and reverse rotation and speed control of the drive motor 161.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
