In practical applications, the sedimentation tank with a size of more than 250 square meters is driven by hydraulic pressure, and the sedimentation tank with a size of less than 250 square meters is directly driven by an electric motor.
[0023] The lever power transmission system 2 is used to transmit the power output by the power device 1 to the mud scraping device 3 .
[0024] The mud scraping device 3 is pulled by the lever power transmission system 2, and reciprocates at the bottom of the pool body to remove sludge.

Example Embodiment

[0025] Embodiment 2, this embodiment further refines the lever power transmission system 2 in Embodiment 1, see figure 2 As shown, it includes: a power device 1 , a lever power transmission system 2 and a mud scraping device 3 connected in sequence.
[0026] Among them, the power device 1 is used to output power, which can be a cylinder device or a motor device. In practical applications, the sedimentation tank with a size of more than 250 square meters is driven by hydraulic pressure, and the sedimentation tank with a size of less than 250 square meters is directly driven by an electric motor.
[0027] The lever power transmission system 2 specifically includes: a first power transmission device 21 for transmitting the power output by the power device 1; a second power transmission device 22 for turning the direction of the power transmitted by the first power transmission device 21, turning The final power direction is generally consistent with the moving direction of the mud scraping device 3; the third power transmission device 23 is used for pulling the mud scraping device 3 with the power transmitted by the second power transmission device 22.
[0028] The mud scraping device 3 is pulled by the lever power transmission system 2, and reciprocates at the bottom of the pool body to remove sludge.

Example Embodiment

[0029] Embodiment 3. This embodiment further refines the first, second, and third power transmission devices and mud scraping devices in the lever power transmission system 2 in embodiment 2. See image 3 , 4 , 5, 6, 7, 8, including: cylinder device 11, first push-pull rod 211, angle arm support frame 4, angle arm 221, link arm 222, second push-pull rod 231, guide rod 5, scraper 31, Scraper 32, bottom surface slide rail 6. It is mainly powered by the cylinder device 11, the first power transmission device 21 is made by the first push-pull rod 211, the second power transmission device 22 is made by the angle arm 221 and the link arm 222, and the third power transmission device is made by the second push-pull rod 231 The device 23, the scraper 31 and the scraper 32 are the mud scraping device 3 for the final mud scraping action. Wherein the corner arm support frame 4 is fixed on the pool wall, plays the role of fixing the corner arm 221, one end of the guide rod 5 is fixed on the pool wall, and the other end is sleeved in the second push-pull rod 231, and plays the role of guiding the movement of the second push-pull rod 231 . Wherein the angular arm 221 is made up of a horizontal pipe 2211, a vertical pipe 2212, and an inclined pipe 2213 in proportion, the horizontal pipe 2211 and the vertical pipe 2212 are connected in the angular arm support frame 4, the vertical pipe 2212 and the inclined pipe 2213 Connected to one end of the link arm 222 , the horizontal tube 2211 and the inclined tube 2213 are connected to one end of the first push-pull rod 211 . Wherein the scraper 31 is welded on the scraper 32, and the second push-pull rod 231 is welded on the scraper 31, and the three constitute one body to move on the bottom slide rail 6. One end of the second push-pull rod 231 is connected to the link arm 222 , and the other end is sleeved on the guide rod 5 .
[0030] In order to achieve better functions and effects, the mud scraping device 3 can be composed of a scraper 31, a scraper 32 and a cushion layer welded together, wherein the structure of the scraper 31: there is an inclined flat surface 311 in the cross section, a vertical A concave surface 312 and a flat surface 313 with a hollow bottom, the concave surface 312 of which faces the forward conveying direction (ie, faces the sludge conveying direction). exist Figure 9 , 10 In , the relationship between the projected lengths of these surfaces is constructed in a certain scale. The hollow bottom surface and generally inclined flat surface can effectively save energy consumption, and at the same time, the generally vertical concave surface can better restrain the bottom sludge from rising, so as to play the role of the sludge scraper more effectively.
