[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0036] The embodiments of this utility model will be described below based on its overall structure.
[0037] Example 1:
[0038] Dedicated actuators for cleaning the shell side of heat exchangers, such as... Figures 1-5 As shown, the system includes a bracket 1, with a fixed seat 5 and a movable seat 6 connected inside. The movable seat 6 has an "H"-shaped cross-section and is slidably connected to the bracket 1. The top and bottom of the movable seat 6 are connected to a second anti-slip groove 10 and a pointer 11. Two bidirectional lead screws 7 pass through the top of the bracket 1 on both sides. A clamping plate 8 connects the two bidirectional lead screws 7, and the clamping plate 8 is threaded to the bidirectional lead screws 7. The clamping plate 8 is slidably connected to the bracket 1. The bottom of the clamping plate 8 is connected to a first anti-slip groove 9, which abuts against the second anti-slip groove 10. There are two or more movable seats 6, and two or more sets of the second anti-slip groove 10 and pointer 11 are provided. A scale 12 is provided on the top of the bracket 1. The operator rotates the bidirectional lead screw 7. Both ends of the bidirectional lead screw 7 are hexagonal, and the middle area of the bidirectional lead screw 7 is also hexagonal, facilitating operation by hand or wrench and reducing slippage between the operator's hand and the bidirectional lead screw 7. Rotating the screw 7 moves the two clamping plates 8 away from each other, thus separating the first anti-slip texture 9 from the second anti-slip texture 10. This ends the clamping and limiting of the movable seat 6, allowing the operator to adjust its position. Adjusting the position of the movable seat 6 causes the nozzles 3 to shift, adjusting the spacing between the multiple nozzles 3 to accommodate heat exchangers with different tube spacings. Simultaneously, the pointer 11 points to the scale 12, enabling the operator to accurately adjust the position of the movable seat 6 to match the spacing between the multiple nozzles 3. After adjustment, the operator reverses the bidirectional screw 7, bringing the two clamping plates 8 closer together, causing the first anti-slip texture 9 and the second anti-slip texture 10 to engage. The first anti-slip texture 9 and the second anti-slip texture 10 increase friction, while the reverse tightening of the bidirectional screw 7 increases contact pressure, effectively limiting the position of the movable seat 6 and preventing structural loosening and displacement.
