Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0038] like Figure 1-4 As shown, a new type of low-load energy-saving scraper blade walking mechanism includes:

[0039] Two guide rails 1, the two guide rails 1 are arranged in parallel in the pool at an interval;

[0040] A crossbeam 2, both ends of which are connected to two guide rails 1 through running wheels;

[0041] Travel wheels include:

[0042] A first bracket 3 and a second bracket 4, wherein the first bracket 3 and the second bracket 4 are respectively arranged on both sides of the crossbeam 2, and rollers 6 are respectively arranged on the sides of the first bracket 3 and the second bracket 4 that are away from each other;

[0043] The limiting wheel is connected to the first bracket 3 through the connecting frame 5, and the axis of the limiting wheel is perpendicular to the axis of the roller 6.

[0044] Specifically, the guide rail 1 is arranged at the bottom or on the pool to adapt to the use of underwater dredging and surface scraping. The beam 2 travels on the two guide rails 1 through two sets of walking wheels. The first bracket 3 and the second bracket 4 are used to connect the roller 6 for movement, and the original sliding friction is replaced by rolling friction, which reduces the travel resistance and achieves the effect of low power consumption. At the same time, the limiting wheel limits the movement and tilting of the beam 2.

[0045] Furthermore, the limiting wheel is connected to the side wall of the guide rail 1 away from the cross beam 2. The limiting wheel limits the travel path of the cross beam 2 when the two guide rails 1 move away from each other, thereby preventing the cross beam 2 from moving crookedly.

[0046] In this embodiment, the first bracket 3 includes:

[0047] A first vertical plate, the side wall of which is provided with a connecting portion that cooperates with the connecting frame 5;

[0049] Specifically, the first horizontal plate increases the connection stability between the first vertical plate and the cross beam 2, and avoids the concentrated force and easy tearing at the connection of the cross beam 2. The first vertical plate is connected to the connecting frame 5 through the connecting part, and the strength of the connection is strengthened by the connecting part.

[0050] Furthermore, the second bracket 4 is similar in structure to the first bracket 3 and is detachably connected to the crossbeam 2 via a bolt assembly, thereby improving maintenance versatility and convenience.

[0051] In this embodiment, reinforcing ribs are provided between the first vertical plate and the first horizontal plate.

[0052] Specifically, the ribs are used to improve stability and avoid deformation.

[0053] In this embodiment, the connecting frame 5 is J-shaped or L-shaped, one end of the connecting frame 5 is provided with an assembly hole matched with the connecting portion, and the other end of the connecting frame 5 is provided with a limiting wheel by bending.

[0054] Specifically, the limiting wheel is connected via the connecting frame 5 , so that the limiting wheel and the roller 6 are respectively connected to the adjacent two side surfaces of the rectangular crossbeam 2 .

[0055] In this embodiment, a square pin hole is provided at the other end of the connecting frame 5, and the limiting wheel is connected to the square pin hole through a round-rotating square pin shaft.

[0056] Specifically, one end of the round-to-square pin is round and connected to the roller 6, and the other end is square and matches with the square pin hole, avoiding the problem of the pin rotating when the traditional round hole and round shaft are rotated together.

[0057] In this embodiment, the connecting portion protrudes outward from the first vertical plate, and a countersunk groove is provided at one end of the connecting portion away from the connecting frame 5 .

[0058] Specifically, the countersunk groove facilitates concealing the bolts fixed to the connecting plate, thereby reducing travel resistance.

[0059] In this embodiment, a reinforcing rib is provided between the connecting portion and the first vertical plate.

[0060] In this embodiment, the crossbeam 2 includes:

[0061] The main board, the first bracket 3 and the second bracket 4 are respectively arranged on both sides of the main board;

[0062] The upper plate and the lower plate are respectively arranged at the upper and lower ends of the main board to form a C-shaped structure with the main board;

[0063] An upper reinforcing rib extending vertically downward is arranged at one end of the upper plate away from the main board, and a lower reinforcing rib extending vertically upward is arranged at one end of the lower plate away from the main board, with a gap being arranged between the upper reinforcing rib and the lower reinforcing rib.

[0064] Specifically, the upper plate and the lower plate are used to improve the stability and support strength of the main board, and the upper reinforcing ribs and the lower reinforcing ribs are used to further strengthen the structural strength of the crossbeam 2 .

[0065] In this embodiment, the roller 6 includes a wheel body and a tire. A dovetail groove is radially arranged on the outer periphery of the wheel body, and a clamping block matching the dovetail groove is arranged on the inner periphery of the tire.

[0066] Specifically, the tire is a polyurethane tire to ensure friction, and the dovetail groove structure ensures connection stability and facilitates disassembly and assembly.

[0067] In this embodiment, the length of the dovetail groove is smaller than the width of the wheel body, and an annular groove is provided on the outer periphery of the tire.

[0068] Specifically, ensure that the tire completely covers the wheel body.

[0069] In this embodiment, a new type of low-load energy-saving scraper scraper travel mechanism is used, taking the use of a new type of non-metallic chain scraper as an example. The new type of non-metallic chain scraper adopts a double-row chain traction form, and a scraper is installed every 3 meters on the traction chain of the equipment, which is formed into a ring through chain links. The scraper is equipped with a scraper travel mechanism to ensure that the scraper operates with high efficiency, moves slowly at the bottom of the pool, and scrapes the sludge at the bottom of the pool into the sludge tank at the end of the pool. At the same time, a track is provided on the pool surface to scrape the scum and oil on the pool surface into the scum tank, creating conditions for mud and slag discharge.

[0070] Working principle: The reduction drive device transmits power to the driven sprocket, driving the scraper on the working chain to make directional rotation and continuous operation. When at the bottom of the pool, the chain drives the scraper to move in the opposite direction of the water flow, pushing the sediment sludge at the bottom of the pool into the sludge collecting tank during the movement. When running on the water surface, the moving scraper can push the scum to the outlet and discharge it from the slag discharge pipe.

[0071] The original sliding friction is replaced by rolling friction, which reduces the travel resistance and achieves the effect of low power consumption. At the same time, the limiting wheel limits the movement and tilt of the beam 2.

[0072] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
