[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A high-efficiency heat storage electric boiler comprises an electric boiler box 1, the outer wall of one side of the electric boiler box 1 is in an open state, the outer wall of the electric boiler box 1 is rotatably connected with a sealing door panel 2, the inner wall of the electric boiler box 1 is fixedly connected with multiple groups of left plywood 5, the electric boiler box 1 is slidably connected with multiple groups of right plywood 6, the number of multiple groups of right plywood 6 is the same as the number of multiple groups of left plywood 5, a heating box 4 is installed at the bottom of the electric boiler box 1, the outer wall of the electric boiler box 1 is rotatably connected with a threaded rod 12, the threaded rod 12 is connected with a slide plate 7 through a connecting mechanism, the slide plate 7 is fixedly connected with multiple groups of right plywood 6, the connecting mechanism comprises a slider 13 threadedly connected to the threaded section of the threaded rod 12, a slider 10 is installed on the outer wall of the slider 13, the slider 10 penetrates the body of the electric boiler box 1 and is connected with the slide plate 7, a stuffing box 11 is installed at the joint between the slider 10 and the electric boiler box 1, the stuffing box 11 is slidably connected to the slider 10, and the stuffing box 11 is installed on the outer wall of the electric boiler box 1.

[0022] The slide plate 7 is driven to slide by means of the threaded rod 12, which drives multiple groups of right clamps 6 to slide, and cooperates with the set left clamp 5 to clamp and fix the solid heat storage brick. Compared with the clamping method of the spring 15 in the comparative document, the mechanical structures such as the threaded rod 12 and the slide plate 7 can maintain their performance better than the spring in a high temperature environment, and are not easily affected by thermal expansion or high temperature fatigue. It should be noted that the set stuffing box 11 is a device commonly used for rotating or reciprocating motion sealing, which contains elements for compressing the packing to prevent the generated hot air from escaping from the connection point of the slide rod 10.

[0023] Reference Figure 2 and Figure 3The slide rod 10 is slidably connected to the outer wall of the slider 13, and the end of the slide rod 10 is fixedly connected to the limit block 14. The radius of the limit block 14 is larger than the radius of the slide rod 10. A spring 15 is sleeved on the outer wall of the slide rod 10, one end of the spring 15 is fixedly connected to the slider 13, and the other end of the spring 15 is fixedly connected to the limit block 14. The side wall of the electric boiler box 1 is fixedly connected to the side plate 8, and the outer wall of the side plate 8 is L-shaped. The side plate 8 is rotatably connected to the threaded rod 12, and the outer wall of the side plate 8 is fixedly connected to the servo motor 9, and the end of the output shaft of the servo motor 9 is fixedly connected to the threaded rod 12. Through holes are opened in the inner bottom of the left clamping plate 5 and the right clamping plate 6, and a fan 3 is installed outside the electric boiler box 1.

[0024] When the threaded rod 12 rotates, the driving slider 13 slides inward or outward, and the set spring 15 is in a stretched or compressed state, and at the same time drives the slide plate 7 to slide. It should be noted that when the solid heat storage brick is heated, thermal expansion will occur, causing its size to change, and the setting of the spring 15 can adapt to this change to ensure the force when the right clamping plate 6 is clamped. At the same time, the set spring 15 is externally placed on the outside of the electric boiler box 1 to avoid the influence of high temperature on the spring 15.

[0025] In the utility model, the specific function of the device is: when using the device, the solid heat storage brick is placed on the upper end of the left clamping plate 5, and the threaded rod 12 is driven to rotate by the servo motor 9. The slider 13 on its threaded section drives the slide plate 7 to slide inward, and drives multiple groups of right clamping plates 6 to slide to one side during sliding, thereby clamping and fixing multiple groups of solid heat storage bricks. Compared with the spring clamping method in the comparative document, it can provide sufficient clamping force, thereby achieving stable fixation of the solid heat storage bricks.

[0026] During the heating process, the solid heat storage bricks in the electric boiler box 1 experience a certain amount of thermal expansion. At this time, the spring 15 provided in the device can flexibly respond to this thermal expansion by stretching or compressing, thereby ensuring that the multiple groups of right clamps 6 are always in contact with the outer wall of the solid heat storage bricks, thereby ensuring stability during clamping.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
