Description

Technical Field

[0001] This invention relates to the field of ice-breaking technology for pump stations, and more particularly to a rotary pendulum ice-breaking device. Background Technology

[0002] The Shuangwangcheng Reservoir, located in Weifang City, receives water through four pumping units at its pumping station. In recent years, frequent extreme winter weather has led to widespread freezing of the water near the pumping station. During the initial freezing and thawing stages, ice blocks move rapidly with the water flow, accumulating in front of the sludge removal machine in the forebay. As the ice accumulates, the water level in the forebay drops sharply, causing the pumping units to malfunction. Stopping the pumping units significantly reduces the amount of water diverted into the reservoir. Therefore, it is necessary to break up the ice in the forebay. Conventional ice-breaking methods mostly involve manual knocking, but this method is ineffective, labor-intensive, and inefficient. Electric heating is also used for melting ice, but this method is energy-intensive and slow. Additionally, chemical de-icing agents are sometimes used, but this pollutes the water and disrupts the reservoir's ecosystem balance, failing to meet the requirements of green water conservancy development. Summary of the Invention

[0032] like Figure 1-8 As shown, a rotary pendulum ice-breaking device includes support components 1 vertically and symmetrically arranged on the side walls of the front pool on both sides of the cleaning machine, and a horizontally arranged ice-breaking mechanism 2 connected to the support components 1 on the corresponding side through sliding components 3 arranged at its left and right ends. Each of the two support components 1 is provided with a lifting mechanism 4 that cooperates with the sliding component 3 on the corresponding side.

[0033] Optionally, the support assembly 1 includes longitudinal channel steels 11 arranged symmetrically on the left and right, and the two longitudinal channel steels 11 are connected by a number of connecting channel steels 12 arranged along their height direction. Support beams 13 connected to the longitudinal channel steels 11 on both sides are provided horizontally at the bottom of each connecting channel steel 12, and transverse channel steels 14 are provided at the top of the two longitudinal channel steels 11.

[0034] Optionally, the sliding assembly 3 includes a movable plate 31 vertically arranged on the front side of the two longitudinal channel steels 11, and linear guide rails 32 vertically arranged on the inner wall of the front side of the two longitudinal channel steels 11 along their height direction. L-shaped brackets 33 are symmetrically arranged on the left and right sides of the rear side wall of the movable plate 31. The two L-shaped brackets 33 are respectively engaged with the linear guide rails 32 on the corresponding side. A sliding seat 34 that cooperates with the linear guide rails 32 on the corresponding side is vertically arranged on the L-shaped brackets 33.

[0035] Optionally, pulley housings 35 are provided at the four corners of the movable plate 31 corresponding to the positions of the two longitudinal channel steels 11. A pulley 36 is vertically mounted inside each pulley housing 35, with the rear side of the pulley 36 extending backward through the movable plate 31 and abutting against the front outer wall of the corresponding longitudinal channel steel 11. The pulleys 36 at the four corners reduce friction with the two longitudinal channel steels 11, allowing the movable plate 31 to move smoothly up and down.

[0036] Optionally, the lifting mechanism 4 includes a fixed channel steel 41 that is vertically connected to the transverse channel steel 14. The front and rear ends of the fixed channel steel 41 extend outward from the transverse channel steel 14, and a screw hoist 42 is provided at the front end of the fixed channel steel 41. A screw 43 is vertically provided on the front side of the longitudinal channel steel 11. The upper end of the screw 43 passes through the fixed channel steel 41 and cooperates with the screw hoist 42, while its lower end is connected to the connector 44. A hinge seat 45 that is hinged to the connector 44 is provided on the front side wall of the movable plate 31 at the position corresponding to the connector 44.

[0037] Optionally, the ice-breaking mechanism 2 includes a horizontally arranged rotating roller 21, and bearing seats 22 symmetrically arranged on two moving plates 31. The two shaft ends of the rotating roller 21 are respectively engaged in the bearing seats 22 on the corresponding side, wherein the shaft end on the right side protrudes from the bearing seat 22 and is connected to the driven gear 23. A drive motor 24 is horizontally arranged on the moving plate 31 above the driven gear 23. The drive motor 24 is connected to the moving plate 31 via a motor bracket 25. A reducer 26 is provided at the output end of the drive motor 24. A transmission gear 27 that meshes with the driven gear 23 is provided on the output shaft of the reducer 26. Several sets of ice-breaking components 28 are provided on the side wall of the rotating roller 21. The ice-breaking component includes a support hinge seat 2801 fixedly connected to the side wall of the rotating roller 21. The inner end of an arm 2802 is movably hinged to the support hinge seat 2801.

[0038] Optionally, a load-bearing bracket 2901 is provided on the movable plate 31 between the bearing housing 22 and the rotating roller 21, which engages with the shaft end of the rotating roller 21. An arc-shaped groove 2902 is provided within the load-bearing bracket 2901, and a bearing 2903, which engages with the arc-shaped groove 2902, is fitted onto the shaft end of the rotating roller 21. The load-bearing bracket 2901 further provides support for the rotating roller 21, ensuring the smooth rotation of the rotating roller 21. Furthermore, the bearing 2903 reduces friction between the shaft end of the rotating roller 21 and the load-bearing bracket 2901, ensuring the normal rotation of the rotating roller 21.

[0039] Optionally, each of the ice-breaking components 28 is evenly distributed in a spiral shape on the side wall of the rotating roller 21.

[0040] Optionally, a buffer seat 2803 is provided on the side wall of the rotating roller 21 behind the supporting hinge seat 2801. A rubber pad 2804 that cooperates with the support arm 2802 is provided on the buffer seat 2803. The buffer seat 2803 is located on the rear side of the supporting hinge seat 2801 along the rotation direction of the rotating roller 21. After striking the ice block, the front end of the support arm 2802 directly abuts against the rubber pad 2804 as the rotating roller 21 rotates. The kinetic energy is released through the buffering effect of the rubber pad 2804, avoiding damage caused by direct contact with the rotating roller 21 and improving the rotational stability of the rotating roller 21.

[0041] Optionally, a support frame 2805 is provided at the front end of the support arm 2802, and a rotating shaft 2806 is horizontally provided inside the support frame 2805. The axis of the rotating shaft 2806 is perpendicular to the axis of the rotating roller 21. An eccentric block 2807 is movably sleeved on the rotating shaft 2806. A spike block 2808 extending out of the support frame 2805 is provided at the front end of the eccentric block 2807. A first locking hole 2809 is opened on the inner wall of the support frame 2805. A second locking hole 2810 is provided on the eccentric block 2807 corresponding to the position of the first locking hole 2809. The two ends of a spring 2811 are respectively fixedly locked in the first locking hole 2809 and the second locking hole 2810 on the corresponding side. When the support arm 2802 swings, its front spike block 2808 will first contact the ice block. When the ice block is thick, the spike block 2808, driven by the eccentric block 2807, will disperse the downward pressure to both sides, thus easily breaking the ice. After breaking the ice, the deflected spike block 2807 will be pulled back to its initial position by the restoring force of the spring 2811.

[0042] When using this device, the horizontal height of the rotating roller 31 needs to be adjusted according to the ice surface height so that the swinging motion of the support arm 2802 can strike the ice surface. By synchronously activating the screw-operated hoists 42 on both sides, the screws 43 move up and down synchronously, while the connecting head 44 pulls the moving plate 31 through the hinge seat 45, thereby adjusting the horizontal height of the rotating roller 21. It should be noted that when the moving plate 31 moves, its inner side moves within the two straight guide rails 32 via sliding seats 34 on the two L-shaped brackets 33. After the position adjustment is completed, the drive motor 24 is started. The output shaft of the drive motor 24 drives the reducer 26, which in turn drives the driven gear 23 to maintain a constant speed rotation through the transmission gear 27, thus rotating the rotating roller 21. As the rotating roller 21 rotates, the support arms 2802, which were originally abutting against the corresponding rubber pads 2804, continuously swing outwards, causing their front ends to strike the ice surface, creating a pendulum effect. In addition, when the support component 1 is installed and fixed on the front side wall, holes can be drilled in the rear side walls of the longitudinal channel steel 11, connecting channel steel 12, and transverse channel steel 14, and fixed with bolts. Holes can also be drilled at the rear end of the fixing channel steel 41, and bolts can be used to fix it to the bank. Its structural design is reasonable, using mechanical methods to replace manual ice breaking, completely eliminating the damage to water quality caused by chemical de-icing agents, greatly reducing energy consumption, and improving ice breaking efficiency. This prevents ice from accumulating in the forebay, ensures the normal operation of the water pump unit, and solves the problems existing in the prior art.
