DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1

[0035] A new type of submersible mixer, such as Figure 1 - Figure 5 As shown, it includes a mounting frame 1, a driver 6 and a stirring blade 7, wherein the length of the mounting frame 1 is greater than the width of the sewage tank at the installation position, and the mounting frame 1 is installed on the top of the side wall of the sewage tank by bolts, so that the position of the mounting frame 1 is fixed;

[0036] Specifically, a moving seat 2 is slidably installed in the mounting frame 1, and a transmission frame 5 fixedly connected to the driver 6 is provided at the bottom of the moving seat 2, so that the driver 6 is supported by the transmission frame 5 and the moving seat 2. When the moving seat 2 slides in the mounting frame 1, it will drive the driver 6 to move synchronously, so that the driver 6 at this time will move horizontally in the sewage pool, causing the stirring blades 7 to stir the sewage in the sewage pool, so that the device only needs to be set up on the sewage pool to effectively stir the sewage, which greatly reduces the factory's use cost and equipment purchase cost;

[0037] Furthermore, a transmission shaft 8 is rotatably mounted in the transmission frame 5, and a gear 9 is fixedly mounted on the top of the transmission shaft 8, so that the transmission shaft 8 and the gear 9 can rotate synchronously. Since a tooth groove 10 corresponding to the gear 9 is provided in the mounting frame 1, the gear 9 is restricted by the tooth groove 10 when rotating. Since the cross section of the tooth groove 10 is designed in a runway shape, the gear 9 can drive the transmission frame 5 to move laterally when rotating, thereby realizing that the transmission frame 5 drives the driver 6 to move laterally in the sewage pool. Moreover, since the width of the tooth groove 10 is greater than the diameter of the gear 9, the gear 9 can only mesh with the teeth on one side of the tooth groove 10 when rotating, thereby ensuring that the transmission frame 5 can move laterally smoothly. The movable seat 2 is provided with a sliding block 3 rotatably connected to the transmission shaft 8, so that the top of the transmission shaft 8 is slidably connected to the movable seat 2 through the sliding block 3, and then when the gear 9 is engaged with the turning position of the tooth groove 10, the transmission shaft 8 can move with the gear 9, so that the transmission frame 5 can reciprocate in the sewage pool, further ensuring that the stirring blade 7 can effectively stir the sewage, and at the same time, a guide block 91 is installed on the top of the gear 9, and a runway-shaped guide groove slidably connected to the guide block 91 is also provided in the top of the mounting frame 1, so that the movement of the gear 9 is further restricted, further ensuring that the gear 9 can smoothly perform the runway-shaped movement.

[0038] See also Figure 2 - Figure 5 A transmission cylinder 4 fixedly connected to the top of the transmission frame 5 is fixedly installed at the bottom of the slider 3, so that when the moving seat 2 drives the slider 3 to slide horizontally in the mounting frame 1, the slider 3 will drive the transmission frame 5 to slide through the transmission cylinder 4, and because a slide groove 21 for the slider 3, the transmission cylinder 4 and the transmission shaft 8 to slide is opened through the moving seat 2, when the gear 9 starts to drive the moving seat 2 to reset, the slider 3, the transmission cylinder 4 and the transmission shaft 8 will slide in the slide groove 21, and the slide groove 21 will further ensure that the gear 9 will move smoothly along the tooth groove 10, ensuring that the transmission frame 5 can smoothly drive the driver 6 to reciprocate in the sewage pool.

[0039] See also Figure 2 , Figure 3 and Figure 5A T-shaped groove for sliding the moving seat 2 and the transmission cylinder 4 is opened in the mounting frame 1, ensuring that the moving seat 2 can smoothly perform transverse reciprocating motion in the mounting frame 1, and at the same time ensuring that the transmission cylinder 4 can be smoothly fixedly connected to the transmission frame 5 and the slider 3, and at the same time the T-shaped groove is communicated with the tooth groove 10, and two sets of pulleys 22 are symmetrically installed on the outer walls of both sides of the moving seat 2, the two sets of pulleys 22 are also located in the T-shaped groove, and at the same time the outer walls of the two sets of pulleys 22 are in contact with the inner walls of the T-shaped groove, so that when the moving seat 2 slides, the two sets of pulleys 22 will restrict the moving seat 2, while ensuring the smoothness of the sliding of the moving seat 2, ensuring the stability of the moving position of the moving seat 2, and In addition, multiple groups of ball bearings in contact with the inner wall of the T-slot are symmetrically installed on the outer walls of the upper and lower ends of the movable seat 2. The ball bearings can reduce the wear between the movable seat 2 and the inner wall of the T-slot when sliding, reduce the sliding resistance and extend the service life of the movable seat 2. In addition, multiple groups of pulleys 41 in contact with the inner wall of the T-slot are installed at equal angles on the outer wall of the transmission cylinder 4, so that when the transmission cylinder 4 slides, it is the pulley 41 that contacts the inner wall of the T-slot, thereby reducing the wear between the transmission cylinder 4 and the T-slot when sliding. In addition, because the bottom cross-section of the T-slot is designed in the shape of a runway, it is ensured that the transmission cylinder 4 can slide smoothly in the T-slot, and further ensure that the driver 6 will reciprocate in the sewage pool.

[0040] See also Figure 3 , a transmission assembly for driving the transmission shaft 8 to rotate is provided in the transmission frame 5 and the driver 6, and the transmission assembly is driven by the driver 6, and the transmission assembly consists of a pulley 11, a pulley 2 12 and a bevel gear transmission group 13, wherein a pulley 11 fixedly connected to the transmission shaft 8 is rotatably installed in the transmission frame 5, and a pulley 2 12 connected to the pulley 11 by a belt is also installed in the transmission frame 5, so that the transmission shaft 8 will rotate synchronously with the pulley 11 and the pulley 2 12, and the bevel gear transmission group 13 in the transmission assembly is installed on the driving shaft of the driver 6, and the other end of the bevel gear transmission group 13 is fixedly connected to the pulley 2 12, so that when the driver 6 is running, the bevel gear transmission group 13 in the transmission assembly will start to operate, so that the pulley 11 and the pulley 2 12 start to drive the transmission shaft 8 to rotate under the action of the belt, and then the transmission shaft 8 will rotate with the operation of the driver 6, so that after the driver 6 is started, the transmission frame 5 will drive the driver 6 to move in the sewage pool.

[0041] It should be noted that the transmission ratio of the transmission assembly in the present invention can be adjusted according to the actual rotational speed and the speed at which movement is required. If necessary, a gearbox can be installed in the transmission frame 5 to ensure that the rotational speed of the gear 9 is relatively slow. Since the speed change design is a prior art, it will not be described in detail here and is not shown in the accompanying drawings. Embodiment 2

[0042] A new type of submersible mixer, such as Figure 1 - Figure 7 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be repeated here. The difference is that a supporting mechanism for supporting the transmission frame 5 is installed at the bottom of the mounting frame 1, and the supporting mechanism is composed of a supporting plate 14 and a supporting frame 15. The supporting plates 14 in the supporting mechanism are fixedly installed on the outer walls of both sides of the transmission frame 5, so that the transmission frame 5 will drive the supporting plates 14 to slide synchronously when sliding, and the supporting frame 15 in the supporting mechanism is bolted to the bottom of the mounting frame 1. Because the supporting plate 14 is located at the top of the supporting frame 15, and a plurality of groups of balls in contact with the supporting frame 15 are arranged at the bottom of the supporting plate 14, so that the supporting plate 14 is slidably connected with the supporting frame 15 through the balls, so that the supporting plate 14 is supported by the supporting frame 15 when sliding, further ensuring the stability of the transmission frame 5 when sliding, and effectively reducing the probability of the transmission frame 5 shaking significantly when sliding;

[0043] Furthermore, because the spacing between the outer ends of the two support plates 14 is greater than the width of the support frame 15, after the gear 9 moves to the turning position of the tooth groove 10, when the transmission frame 5 starts to move forward and backward, the support plate 14 at this time will still be located above the support frame 15, ensuring that the transmission frame 5 will always be supported by the support frame 15 and the support plate 14, and guide plates 16 for guiding the support plates 14 are installed at both ends of the support frame 15. The guide plate 16 is designed as an arc plate, and the arc center point of the guide plate 16 and the center point of the corner position of the tooth groove 10 are located on the same vertical line, so that when the support plate 14 slides, its outer end will conflict with the inner wall of the guide plate 16. At this time, the guide plate 16 will guide the support plate 14, thereby further ensuring that when the gear 9 runs to the corner position with the tooth groove 10, it can smoothly mesh with the teeth at the corner position of the tooth groove 10, ensuring that the gear 9 can rotate to its original position.

[0044] The working principle of the utility model is as follows: when using the device, firstly, the mounting frame 1 is fixedly mounted on the sewage pool, and then the driver 6 is started, so that the stirring blade 7 starts to operate to treat the sewage. At the same time, the driver 6 will also drive the bevel gear transmission group 13 to operate, so that it drives the transmission shaft 8 to start operating through the pulley 11 and the pulley 2 12. At this time, the gear 9 will start to rotate, causing the gear 9 to start to drive the moving seat 2 to move horizontally under the action of the tooth groove 10, thereby causing the driver 6 to start to move. The tooth groove 10 will use its own structure to guide the gear 9, so that the gear 9 performs reciprocating horizontal motion in the mounting frame 1, so that the driver 6 can perform horizontal reciprocating motion in the sewage pool, effectively increasing the stirring area of ​​a group of stirring blades 7, effectively reducing the number of drivers 6 and stirring blades 7, and being more energy-saving.

[0045] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
