DETAILED DESCRIPTION

[0017] See also Figure 1-3 The utility model provides the following technical solutions: a heat storage tank, comprising a tank body 1, a connecting pipe 2, a scraper 6 and a drain pipe 7, and also comprising a moving mechanism 3, an adsorption block 4 and a fixing mechanism 5. The bottom and top of the side wall of the tank body 1 are equipped with a connecting pipe 2, the bottom of the tank body 1 is equipped with a drain pipe 7, the side wall of the tank body 1 is equipped with a moving mechanism 3, the adsorption block 4 is slidably installed on the moving mechanism 3, the inner wall of the tank body 1 is equipped with a fixing mechanism 5, and the scraper 6 is installed on the fixing mechanism 5;

[0018] The adsorption block 4 includes an electromagnet 41, a battery 42, a controller 43, a second motor 44, a ball 45, a roller 46 and a guide wheel 47. The adsorption block 4 is slidably mounted on the annular groove 34. The battery 42, the controller 43 and the second motor 44 are installed inside the adsorption block 4. The part of the adsorption block 4 that contacts the side wall of the tank body 1 is installed with an electromagnet 41. The shape of the electromagnet 41 matches the shape of the side wall of the tank body 1. Several ball 45 are installed on the bottom surface of the part of the adsorption block 4 located inside the annular groove 34. The part of the shaft of the second motor 44 that extends out of the adsorption block 4 is installed with a roller 46 that contacts the inner wall of the annular groove 34. Several guide wheels 47 that contact the inner wall of the annular groove 34 are rotatably installed on the side wall of the adsorption block 4.

[0019] The scraper 6 is sucked by the adsorption block 4. When the adsorption block 4 sucks the scraper 6, the fixing mechanism 5 releases the fixing of the scraper 6, so that the adsorption block 4 can move with the scraper 6. As the adsorption block 4 moves, the scraper 6 scrapes off the dirt on the inner wall of the tank body 1. The position of the adsorption block 4 is moved by the moving mechanism 3 to achieve the removal of the dirt on the inner wall of the tank body 1. After the dirt is removed, the sewage pipe 7 is opened to discharge the dirt.

[0020] The operation of the electromagnet 41 and the motor 44 can be controlled by the controller 43. The controller 43 can be remotely controlled, which is convenient for the user to operate the adsorption block 4. The battery 42 is used to supply power to the electromagnet 41, the controller 43 and the motor 44 to avoid affecting the movement of the adsorption block 4 due to the use of the power supply line. By setting the ball 45 and the guide wheel 47, the friction force on the adsorption block 4 during the movement is reduced. After the motor 44 is started, the roller 46 installed on the motor 44 starts to rotate, thereby realizing the movement of the adsorption block 4 on the annular groove 34. The shape of the electromagnet 41 can ensure the attraction effect of the electromagnet 41 on the scraper 6, and the magnetic force of the electromagnet 41 should ensure that the electromagnet 41 can release the fixation of the fixing mechanism 5 at a farther position.

[0021] Specifically, the moving mechanism 3 includes a motor 31, a mounting frame 32, a threaded rod 33, an annular groove 34 and a guide rod 35. The mounting frame 32 is mounted on the bottom of the side wall of the tank body 1, and the threaded rod 33 is rotatably mounted on the mounting frame 32. One end of the mounting frame 32 passes through the bottom of the mounting frame 32 and is then installed on the motor 31. The motor 31 is installed on the bottom surface of the mounting frame 32. The annular groove 34 is installed on the threaded rod 33 by threads, and a plurality of guide rods 35 passing through the annular groove 34 are installed on the top surface of the mounting frame 32.

[0022] The lifting and lowering of the annular groove 34 can be controlled by the cooperation of the motor 31 and the threaded rod 33, so that the adsorption block 4 and the scraper 6 can move in the vertical direction, which is convenient for the scraper 6 to clean the dirt inside the tank body 1. The stability of the annular groove 34 during movement is ensured by setting a guide rod 35.

[0023] Specifically, a protrusion is provided at the opening of the annular groove 34 , a groove matching the protrusion on the annular groove 34 is provided on the adsorption block 4 , and a notch with a width greater than the connecting pipe 2 is left in the annular groove 34 at the position where the connecting pipe 2 is installed on the tank body 1 .

[0024] The adsorption block 4 can be fixed by cooperating with the protrusion set at the opening of the annular groove 34 and the groove on the adsorption block 4, ensuring that the adsorption block 4 will not fall off from the annular groove 34 during movement. The notch left on the annular groove 34 can prevent the connecting pipe 2 from affecting the movement of the annular groove 34.

[0025] Specifically, the fixing mechanism 5 includes a spring 51, a fixing block 52 and a fixing frame 53. The fixing frame 53 is installed on the inner side wall of the tank body 1. A groove is provided on the inner wall of the tank body 1 at a position in the middle of the two fixing frames 53. The fixing block 52 is installed inside the groove on the inner wall of the tank body 1 through the spring 51. A groove matching the fixing block 52 is provided on the scraper 6.

[0026] The spring 51 ensures that the fixing block 52 can quickly return to its original position, ensuring the fixing effect of the fixing mechanism 5 on the scraper 6. The fixing frame 53 can ensure that the scraper 6 will not fall off the inner wall of the tank body 1 during the fixing process. The fixing frame 53 can also scrape off the dirt attached to the surface of the scraper 6 during the movement of the scraper 6.

[0027] Specifically, both the fixing block 52 and the scraper 6 can be attracted by the electromagnet 41 .

[0028] When the fixed block 52 is attracted by the electromagnet 41, the fixed block 52 moves toward the electromagnet 41, and the fixed block 52 is separated from the scraper 6. At this time, the fixation of the scraper 6 is released, and the scraper 6 is attracted by the electromagnet 41 to ensure that the scraper 6 can move with the movement of the adsorption block 4, so that the user can clean the dirt on the inner wall of the tank body 1 without opening the tank body 1.

[0029] Specifically, when the adsorption block 4 moves to the edge of the annular groove 34 , the distance between the edge of the scraper 6 and the edge of the annular groove 34 is greater than half the distance between the notches of the annular groove 34 , and the shape of the scraper 6 is an arc block that matches the inner wall of the tank body 1 .

[0030] The width of the scraper 6 ensures that the scraper 6 can clean the dirt on the inner wall of the tank body 1 located on the same vertical plane as the position where the connecting pipe 2 is installed, and the shape of the scraper 6 ensures that the scraper 6 can fit the inner wall of the tank body 1, ensuring the effect of the scraper 6 in cleaning the dirt.

[0031] The working principle and use process of the utility model are as follows: by moving the moving mechanism 3 and the adsorption block 4, the adsorption block 4 is located at the position where the fixing mechanism 5 is installed on the tank body 1, the electromagnet 41 is started, the fixing block 52 and the scraper 6 are attracted by the electromagnet 41, the motor 2 44 is started, and the adsorption block 4 is moved inside the annular groove 34 by the roller 46. After the adsorption block 4 moves from one end of the annular groove 34 to the other end, the motor 1 31 is started, and the position of the annular groove 34 is adjusted by the cooperation of the threaded rod 33 and the annular groove 34, and then the adsorption block 4 is controlled to move on the annular groove 34 again, and the above steps are repeated until the cleaning is completed, the sewage pipe 7 is opened to discharge the scraped dirt, the sewage pipe 7 is closed, the moving mechanism 3 and the adsorption block 4 are controlled to return to the position where the fixing mechanism 5 is located, the electromagnet 41 is closed, and the scraper 6 is fixed by the fixing block 52 and the fixing frame 53.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
