Description

Technical Field

[0001] The utility model belongs to the technical field of rubber ball collecting, and in particular relates to a ball collecting net plate opening and closing mechanism which can quickly collect balls. Background Art

[0002] The ball collecting device is an indispensable device in the condenser cooling tube cleaning process, in which the ball collecting net plays a vital role. In order to ensure that the sponge rubber balls can continuously and effectively clean the condenser tubes, this device must ensure the continuous supply and timely recovery of the rubber balls. Specifically, the rubber balls need to be continuously fed into the cleaning system, and the cleaned rubber balls need to be collected through the ball collecting net so that they can be reused for cooling tube cleaning.

[0003] However, the currently widely used ball collection net design relies on pneumatic actuators and realizes the opening and closing operation through the mirror drive of the connecting rod and the swing arm. Although this design is common, it has significant shortcomings. First, since the connecting rod swing arm mechanism involves multiple intermediate transmission components, the accumulation of errors is difficult to avoid, which directly affects the accuracy of the ball collection function. Secondly, the transmission path of the mechanism is long, which may not only lead to a decrease in mechanical efficiency, but also in the high-speed motion state, the connecting rod swing arm mechanism may increase the dynamic load due to the action of inertia force, further weakening its performance.

[0004] Therefore, it is very necessary to invent a ball collecting net plate opening and closing mechanism that can quickly collect balls. Utility Model Content

[0006] The ball collecting net plate mechanism includes an opening and closing base, a double worm, a driving component, an open worm wheel and a ball collecting net plate. The opening and closing base is fixedly mounted on the outside of the ball collector housing. Either end of the double worm rotatably mounted on the opening and closing base is fixed to the output end of the driving component. The driving component is fixedly mounted on the opening and closing base. The double worm is meshed and connected with the two open worm wheels, and the rotating shaft of the ball collecting net plate is fixedly connected to the open worm wheel.

[0007] Preferably, the opening and closing base is a "U"-shaped base structure, and there are two opening and closing bases in total, which are mirror-imaged and arranged on the outside of the ball receiver housing. Either end of the double worm gear rotates through one of the opening and closing bases and is fixed to the output end of the driving component, which is a motor.

[0008] Preferably, the double worm is located between the two open worm wheels, and the double worm is provided with two sections of spirals with opposite rotation directions, that is, one section is a left spiral and the other section is a right spiral, and the two sections of spirals are respectively meshed with two different open worm wheels.

[0009] Preferably, the opening worm gears are arranged in mirror symmetry, the transmission coefficients of the two opening worm gears and the two sections of the double worm are different, the spiral angle of one section of the double worm and the spiral angle of one of the opening worm gears are greater than the spiral angle of the other section and the spiral angle of the other opening worm gear, and when the double worm rotates one circle, the distances advanced by the two opening worm gears are different, resulting in a difference in the rotation speeds of the two opening worm gears.

[0010] Preferably, the rotating shafts of the two ball collecting nets are rotatably installed in the ball collecting device housing, and either end of the rotating shaft rotates through the ball collecting device housing and is respectively fixed to the two open worm gears outside thereof.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] This utility model has made a major innovation in transmission technology, abandoning the traditional mirror-image drive method that relies on pneumatic actuators through connecting rods and swing arms, and instead introducing a double-helix worm gear design. This innovative design significantly improves the ability to accurately control the ball collecting net. Specifically, the two sections of the double worm have opposite helical rotation directions and mesh with the two opening worm gears respectively, ensuring that under the same driving force, the ball collecting nets on both sides can achieve synchronous and symmetrical opening and closing movements, thereby greatly improving operating efficiency.

[0013] The use of worm and worm gear transmission mechanism not only brings many advantages to the equipment, such as smooth transmission, low noise, and strong load-bearing capacity, but more importantly, the self-locking function of the worm and worm gear transmission effectively prevents the ball collecting net from accidentally opening or closing due to power failure or external force, greatly improving the safety and reliability of the equipment.

[0021] As attached Figure 1 To Attachment Figure 3 As shown:

[0022] The utility model provides a ball collecting net plate opening and closing mechanism capable of quickly collecting balls, comprising a ball collecting device shell 1, a ball collecting net plate mechanism 2, a manhole 3 and a ball outlet 4, wherein the ball collecting net plate mechanism 2 is installed on the ball collecting device shell 1, the manhole 3 and the ball outlet 4 are fixedly installed on the ball collecting device shell 1, and there are two ball outlets 4 in total.

[0023] The ball collecting net plate mechanism 2 includes an opening and closing base 21, a double worm 22, a driving component 23, an opening worm wheel 24 and a ball collecting net plate 25. The opening and closing base 21 is fixedly mounted on the outside of the ball collector housing 1. Either end of the double worm 22 rotatably mounted on the opening and closing base 21 is fixed to the output end of the driving component 23. The driving component 23 is fixedly mounted on the opening and closing base 21. The double worm 22 is meshed and connected with the two opening worm wheels 24, and the rotating shaft of the ball collecting net plate 25 is fixedly connected with the opening worm wheel 24. The ball collecting net plate mechanism 2 significantly improves the ability to accurately control the ball collecting net plate. It not only brings many advantages to the equipment, such as stable transmission, low noise, and strong bearing capacity, but more importantly, the self-locking function of the worm and worm wheel transmission effectively prevents the ball collecting net plate from being accidentally opened or closed due to power failure or external force. Example

[0024] Specifically, the opening and closing base 21 is a "U"-shaped base structure. There are two opening and closing bases 21, which are mirror-imaged and arranged outside the ball collector housing 1. Either end of the double worm 22 rotates through one of the opening and closing bases 21 and is fixed to the output end of the driving component 23. The driving component 23 uses a motor as a power source. The motor has the advantages of high efficiency, stability, and easy control, and can ensure that the double worm 22 responds quickly and accurately when needed, thereby realizing precise control of the ball collecting net. This design greatly improves the working efficiency and reliability of the entire ball collector.

[0025] Specifically, the double worm 22 is located between the two open worm wheels 24, forming a compact and efficient transmission structure. The double worm 22 is specially designed with two sections of spirals with opposite rotation directions, that is, one section is a left spiral and the other section is a right spiral. This design enables the two sections of spirals of the double worm 22 to mesh with two different open worm wheels 24 respectively. When the double worm 22 rotates, the left spiral and the right spiral drive the two open worm wheels 24 to rotate in opposite directions respectively. This synchronous and symmetrical rotation method ensures that the ball collecting net plate can be opened and closed smoothly and accurately, thereby improving the operating efficiency and reliability of the entire ball collector.

[0026] Specifically, the opening worm gear 24 is designed to be mirror-symmetrical to ensure that the mechanical structures on both sides can operate synchronously and balanced. The two opening worm gears 24 are meshed with the two spiral sections of the double worm 22, but the transmission coefficients of the two spiral sections and the opening worm gear 24 are different. Specifically, the spiral angle of one section of the double worm 22 and the spiral angle of an opening worm gear 24 meshing therewith are relatively large, while the spiral angle of the other section and the spiral angle of another opening worm gear 24 meshing therewith are relatively small. This design makes it possible for the two opening worm gears 24 to advance different distances when the double worm 22 rotates one circle. Due to the difference in transmission coefficients, the two opening worm gears 24 will produce different rotation speeds and displacements under the drive of the double worm 22. This differentiated design is used to compensate for the situation where the ball receiving net 25 cannot be opened and closed synchronously because the two opening worm gears 24 are not arranged on the same horizontal line.

[0027] Specifically, the rotating shafts of the two ball collecting net plates 25 are rotatably installed in the ball collecting device housing 1, and either end of the rotating shaft rotates through the ball collecting device housing 1 and is respectively fixed to the two open worm gears 24 outside thereof. Example

[0028] First, the driving component 23 (motor) is started, and the output end of the motor is fixed to one end of the double worm 22, thereby driving the double worm 22 to start rotating. The double worm 22 has two sections of helices with opposite rotation directions, that is, one section is a left helix and the other section is a right helix.

[0029] Then, since the two helical sections of the double worm 22 are respectively meshed with the two open worm wheels 24 , when the double worm 22 rotates, the left helical section and the right helical section respectively drive the two open worm wheels 24 to rotate in opposite directions.

[0030] Next, because the transmission coefficients of the two opening worm wheels 24 and the two sections of the spiral of the double worm 22 are different, the distances advanced by the two opening worm wheels 24 are different when the double worm 22 rotates one circle. This differentiated design is used to make up for the situation that the two opening worm wheels 24 cannot be opened and closed synchronously due to the fact that the two opening worm wheels 24 are not arranged on the same horizontal line. Specifically, the spiral with a larger transmission coefficient and the opening worm wheel 24 will advance a farther distance, thereby realizing the synchronous opening and closing of the two ball receiving nets 25.

[0031] Finally, the rotating shafts of the two ball collecting nets 25 are rotatably installed in the ball collecting housing 1, and one end of the rotating shaft rotates through the ball collecting housing 1 and is respectively fixed to the two opening worm gears 24 outside thereof. Therefore, when the opening worm gear 24 rotates, the rotating shafts of the ball collecting nets 25 are driven to rotate, thereby realizing the opening and closing action of the ball collecting nets 25.

[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
