[0029] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text.

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] Example 1: Please refer to the attached Figure 1-Figure 5 A non-negative pressure tank automatic cleaning device comprises a horizontally arranged tank body 1, a laterally arranged support frame 2 is provided on the top of the tank body 1, a load-bearing connecting member 3 which moves back and forth along its length direction is provided below the support frame 2, a translation driving mechanism 4 for driving the load-bearing connecting member 3 to translate is provided in the support frame 2; a high-pressure pipe 5 located in the width direction of the tank body 1 is provided at a position corresponding to the load-bearing connecting member 3 in the tank body 1, a rotation driving mechanism 6 for driving the high-pressure pipe 5 to rotate around its own axis is installed on the load-bearing connecting member 3, and high-pressure nozzles 51 are evenly installed on the high-pressure pipe 5.

[0033] The end of the high-pressure pipe 5 facing away from the rotation drive mechanism 6 is connected to a water supply pipe 7, and the water supply pipe 7 is rotationally connected to the high-pressure pipe 5 through a bearing, and a pumping mechanism 8 connected to the water supply pipe 7 is fixed on the outer surface of the tank body 1 (the pumping mechanism 8 can adopt a conventional pumping device in the prior art, and its specific structure is not repeated in this solution). The high-pressure nozzle 51 located at the end of the high-pressure pipe 5 is tilted.

[0034] A water inlet pipe 11 is connected to one side of the upper portion of the tank body 1 , a water outlet pipe 12 is connected to the middle position of the bottom of the tank body 1 , and a sewage pipe 13 is connected to one side of the bottom of the tank body 1 .

[0035] When in use, close the water inlet pipe 11 and the water outlet pipe 12, open the sewage pipe 13, and start the pumping mechanism 8. The cleaning liquid or water is sent into the high-pressure pipe 5 through the pumping mechanism 8 and the water supply pipe 7, and is sprayed out through the high-pressure nozzle 51 to flush and clean the inner wall of the tank body 1; and the translation drive mechanism 4 drives the load-bearing connecting part 3, the rotation drive mechanism 6, the high-pressure pipe 5 and the high-pressure nozzle 51 to perform reciprocating translation between the two ends in the tank body 1; the rotation drive mechanism 6 drives the high-pressure pipe 5 to rotate around its own axis, and the direction of the high-pressure nozzle 51 can be adjusted. Specifically, when the high-pressure nozzle 51 is facing downward, the lower inner wall of the straight cylindrical part of the tank body 1 can be cleaned; when the high-pressure nozzle 51 is facing upward, the upper inner wall of the straight cylindrical part of the tank body 1 can be cleaned; the high-pressure nozzle 51 can also be adjusted to the left and right directions, and the inclined setting of the high-pressure nozzle 51 at the end of the high-pressure pipe 5 and the lateral movement of the high-pressure nozzle 51 can be used to clean the corresponding areas on the front and back sides of the inner wall of the tank body 1 blocked by the water supply pipe 7, thereby achieving comprehensive cleaning of the inner wall of the straight cylindrical part of the tank body 1; when the high-pressure pipe 5 moves to both ends, the high-pressure pipe 5 is driven to rotate around its own axis through the rotating drive mechanism 6, and the high-pressure nozzle 51 is driven to reciprocate within a certain angle, so that the inner wall of the curved surface part at both ends of the tank body 1 can be cleaned, thereby achieving comprehensive cleaning of the inner wall of the tank body.

[0036] In order to improve the cleaning effect, especially when there is a lot of dirt accumulated on the bottom of the tank body 1, when cleaning the straight part of the tank body 1, the high-pressure pipe 5 is driven to deflect around its own axis by a certain angle (the angle is adjustable) by rotating the driving mechanism 6 and then driving the high-pressure pipe 5 to translate, so as to change the spray cleaning angle of the high-pressure nozzle 51. In application, the high-pressure nozzle 51 can be adjusted in sequence to clean the inner wall of the straight part of the tank body 1 multiple times at different spray cleaning angles, so as to achieve the purpose of enhancing the cleaning effect.

[0037] In the later stage of cleaning, the high-pressure nozzle 51 is moved from one end of the tank body 1 to the other end at a certain angle by rotating the driving mechanism 6, so as to push the cleaning waste liquid in the tank body 1 to be discharged from the tank body 1 in the forward direction, thereby achieving the effect of promoting the discharge of the cleaning waste liquid.

[0038] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0039] The translation drive mechanism 4 includes a lead screw 41 horizontally arranged in the support frame 2 and a slider 42 threadedly mounted on the lead screw 41. One end of the lead screw 41 is connected to a forward and reverse motor 43 located outside the tank body 1, and the other end of the lead screw 41 is connected to the inner wall of the support frame 2 through a bearing. The bearing connector 3 includes a connecting rod 31 fixedly connected to the slider 42 and a bearing plate 32 fixed to the connecting rod 31. The rotation drive mechanism 6 is installed on the bearing plate 32. The bottom of the support frame 2 is provided with a strip opening 21 for the connecting rod 31 to move. The forward and reverse motor 43 drives the lead screw 41 to rotate. Under the limiting effect of the strip opening 21, the slider 42 cannot move laterally with the rotation of the lead screw 41. Through the forward and reverse control of the forward and reverse motor 43, the slider 42 can be driven to perform reciprocating translation, and the connecting rod 31 and the bearing plate 32 are then reciprocated and translated, and the rotation drive mechanism 6 and the high-pressure pipe 5 are driven to perform corresponding translation.

[0040] The high pressure pipe 5 is located at the middle height of the tank body 1, and the connecting rod 31 is a long rod. This arrangement makes the distance between the high pressure pipe 5 and the top and bottom of the inner wall of the tank body 1 not much different, which is convenient for achieving uniform cleaning of the tank body 1.

[0041] The rotation drive mechanism 6 includes a bidirectional motor 61, and the output shafts on both sides of the bidirectional motor 61 are respectively connected to a high-pressure pipe 5, and the load-bearing connector 3 is connected to a protective housing 62 that is covered on the outside of the bidirectional motor 61, and the protective housing 62 is connected to the output shaft of the bidirectional motor 61 through a sealed bearing. The bidirectional motor 61 can drive the two high-pressure pipes 5 to deflect and / or rotate synchronously at the same time; the protective housing 62 can better protect the bidirectional motor 61.

[0042] The pumping mechanism 8 is located at the middle of the top of the tank body 1. After such arrangement, the water supply pipe 7 only needs to be arranged at half the length of the tank body 1 to meet the demand.

[0043] The rest is the same as in Example 1.

[0044] Embodiment 3: This embodiment differs from Embodiment 2 in that:

[0045] The high-pressure pipe 5 is located in the upper part of the tank body 1, and the connecting rod 31 is a short rod.

[0046] There is only one high-pressure pipe 5, and the bidirectional motor 61 is replaced by a unidirectional motor, and the output shaft of the unidirectional motor drives the high-pressure pipe 5 to rotate around its own axis through the gear transmission assembly. The load-bearing connecting member 3 is connected to a protective shell 62 that covers the outside of the unidirectional motor and the gear transmission assembly, and the unidirectional motor is provided with a through hole for the high-pressure pipe 5 to pass through.

[0047] The rest is the same as Example 2.

[0048] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
