Description

Technical Field

[0001] The present application relates to the technical field of rubber ball cleaning, and more specifically, to a ball collecting net with a three-link transmission mechanism. Background Art

[0002] A condenser is a heat exchanger that condenses steam from a steam turbine into water, also known as a rehydrator. Condensers are mainly used in steam turbine power plants and are divided into two types: water-cooled condensers and air-cooled condensers. Scaling of the condenser cooling pipes will reduce productivity: any tiny impurities and scale in the heat exchanger and condenser pipes will reduce productivity and shorten the service life of the machine. For power systems, low productivity means low output of the turbine.

[0003] The condenser rubber ball cleaning device and rubber balls can operate 24 hours a day to remove scale and sediment in the cooling pipes and always maintain the reliable operation of the equipment. In the prior art, an inverted V-shaped ball collecting net is usually used to collect balls. The water flow will drive the rubber balls to impact the ball collecting net from top to bottom, resulting in the bottom of the ball collecting net and the cylinder body not being able to fit together. The working state of the ball collecting net is not stable enough and it is easy to leak balls. In addition, when the rubber balls hit the ball collecting net downward, the rubber balls will be stuck in the grid of the ball collecting net, which increases the resistance of the grid and affects the recovery of the rubber balls.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] Please refer to Figure 1 、 Figure 2 , the present invention provides a technical solution: a ball receiving net with a three-link transmission mechanism, including a ball receiving cylinder body 1, a mesh body 2 is movably sleeved inside the ball receiving cylinder body 1, a ball outlet 7 is fixedly connected to the side of the ball receiving cylinder body 1, and the number of the mesh bodies 2 is two and forms an inverted V-shaped structure. By setting the mesh body 2, the mesh body 2 is mainly used to filter the rubber balls in the water flow, so that the rubber balls are discharged from the ball outlet 7, facilitating the recycling of the rubber balls. A rotating shaft 3 is fixedly connected to the side of the mesh body 2, the rotating shaft 3 is movably sleeved inside the ball receiving cylinder body 1, the front end of the rotating shaft 3 is fixedly connected with a rotating disk 4, a rotating mechanism 6 is fixedly installed on the front surface of the ball receiving cylinder body 1, and the bottom of the output shaft of the rotating mechanism 6 is movably connected with a connecting rod 5. By pushing the connecting rod 5 up or down through the rotating mechanism 6, the rotating disk 4 can be driven to rotate, thereby driving the mesh body 2 to rotate, enabling the mesh body 2 to unfold into an inverted V-shaped or stand up to a parallel state, and the bottom end of the connecting rod 5 is movably connected to the rotating disk 4.

[0028] Please refer to Figure 2 、 Figure 3, a cross bar 8 is fixedly connected inside the ball receiving cylinder body 1. A telescopic rod 9 is fixedly sleeved in the middle of the cross bar 8. By providing the telescopic rod 9, the telescopic rod 9 provides power for the movement of the support rod 10. The telescopic rod 9 can drive one end of the support rod 10 to move up and down. A connecting head 91 is fixedly connected to the bottom of the output shaft of the telescopic rod 9. The connecting head 91 has an inverted T-shaped structure. The support rod 10 is movably sleeved on both sides of the connecting head 91. By providing the connecting head 91, it is convenient for the telescopic rod 9 to connect two support rods 10 at the same time, so that the support rods 10 on both sides can move synchronously. The bottom end of the telescopic rod 9 is movably sleeved with a support rod 10. A connecting seat 11 is fixedly connected to the bottom of the net body 2. One end of the support rod 10 close to the net body 2 is movably sleeved with the connecting seat 11. By providing the support rod 10, the telescopic rod 9 is used to push the support rod 10 to move downward to a horizontal state, so that the support rod 10 supports the bottom of the net body 2, and the bottom of the net body 2 can be attached to the inner wall of the ball receiving cylinder body 1, avoiding the bottom of the net body 2 being washed open by the water flow. The support rods 10 are symmetrically distributed on the left and right sides of the telescopic rod 9.

[0029] Please refer to Figure 2 , Figure 4 , connecting components 12 and socket holes 13 are respectively fixedly installed on the fronts of the two support rods 10. The connecting component 12 includes a sleeve 121 and a metal piston rod 122. By the combined use of the connecting component 12 and the socket hole 13, when the support rod 10 is unfolded to a horizontal state, the metal piston rod 122 is inserted into the interior of the socket hole 13, thereby connecting the left and right support rods 10 together and improving the stability of the support of the support rod 10. The metal piston rod 122 is movably sleeved in the interior of the sleeve 121. The left end of the metal piston rod 122 is inserted into the interior of the socket hole 13. The sleeve 121 is fixedly installed on the front of the right support rod 10. A return spring 123 is movably sleeved in the interior of the sleeve 121. By providing the return spring 123, the return spring 123 gives the metal piston rod 122 a leftward elastic force, so that the metal piston rod 122 can be automatically inserted into the socket hole 13. The return spring 123 is in a compressed state. The return spring 123 is located on the right side of the metal piston rod 122. An electromagnet 124 is fixedly connected to the right side of the sleeve 121. By providing the electromagnet 124, when the net body 2 needs to be rotated to a parallel state, the electromagnet 124 can be energized to generate a magnetic force, and the electromagnet 124 is used to attract the metal piston rod 122 to move to the right, releasing the locking of the support rod 10.

[0030] Please refer to Figures 5 to 6, an internal movable receiving ball grille 14 is sleeved inside the net body 2. The receiving ball grille 14 includes grille rod one 141 and grille rod two 142. The grille rod one 141 and the grille rod two 142 are movably sleeved inside the net body 2. The grille rod one 141 and the grille rod two 142 are paired. By the combined use of the grille rod one 141 and the grille rod two 142, the grille rod one 141 and the grille rod two 142 on both sides of the grille gap 143 rotate outwards. In this way, when the rubber ball is stuck in the grille gap 143, rotating the grille rod one 141 and the grille rod two 142 can push out the rubber ball, thus relieving the situation where the rubber ball is stuck. The grille rod one 141 and the grille rod two 142 are evenly distributed in the net body 2. A grille gap 143 is formed between each pair of the grille rod one 141 and the grille rod two 142. A micro waterproof motor 20 is fixedly connected to the front surface of the net body 2. The micro waterproof motor 20 is in transmission connection with the grille rod one 141.

[0031] Please refer to Figures 6 to 7 , a gear one 15 and a gear four 18 are fixedly sleeved on the top of the grille rod one 141. A gear two 16 is fixedly sleeved on the top of the grille rod two 142. The gear one 15 and the gear two 16 are meshed together. By the combined use of the gear one 15 and the gear two 16, when the grille rod one 141 rotates, the gear one 15 can drive the gear two 16 to rotate, so that the grille rod one 141 and the grille rod two 142 rotate towards each other. A synchronous belt 19 is externally meshed with the gear four 18. The synchronous belt 19 connects the gear four 18 in transmission. By setting the synchronous belt 19 and using the synchronous belt 19 to drive the gear four 18 to rotate, all the grille rod one 141 can be rotated synchronously. A gear three 17 is fixedly sleeved on the top of the grille rod one 141. The gear three 17 is located between the gear one 15 and the gear four 18. A transmission belt 21 is externally connected to the gear three 17 in transmission. By driving the transmission belt 21 to rotate through the micro waterproof motor 20 and then driving the gear three 17 to rotate by the transmission belt 21, the grille rod one 141 can be rotated. The other end of the transmission belt 21 is in transmission connection with the toothed output shaft of the micro waterproof motor 20.

[0032] In summary, for the ball collecting net with a three-link transmission mechanism provided in this application, during use, the rotating mechanism 6 is used to push the connecting rod 5 downward, so that the rotating disk 4 drives the rotating shaft 3 to rotate, and the net body 2 is unfolded into an inverted V-shaped structure. At the same time, the telescopic rod 9 pushes the support rod 10 downward, so that the support rod 10 is unfolded to a horizontal state to support the bottom of the net body 2, improving the stability of the working state of the net body 2. When the support rod 10 is in a horizontal state, the electromagnet 124 in the connecting component 12 is powered off and demagnetized. At this time, the reset spring 123 pops the metal piston rod 122 to the right, so that the metal piston rod 122 is inserted into the inner part of the sleeve hole 13, connecting the left and right support rods 10 together to prevent the two support rods 10 from being bent by external forces. When the rubber balls flow downward with the water flow, the micro waterproof motor 20 drives the grid rod one 141 and the grid rod two 142 to rotate towards each other. In this way, when the rubber balls are stuck in the grid gap 143, the grid rod one 141 and the grid rod two 142 can push out the rubber balls to ensure the recovery of the rubber balls, and that's all.
