[0023] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application and uses. It should be understood that throughout the drawings, the same or similar reference numerals can indicate the same or similar parts or features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and their proportions of the various embodiments of the present disclosure. The specific parts in the specific drawings can be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0024] Please refer to Figures 1-5 , the utility model provides an embodiment:

[0025] A power plant boiler soot blower, including soot blower main body 1, soot blower main body 1 one end is provided with soot blowing pipe 2, soot blower main body 1 one end fixed mounting has mounting bracket 3, and the upper and lower sides of mounting bracket 3 are all provided with recess, recess is all provided with movable mechanism, and movable mechanism is used for the movement of two groups of sliding plates 5, and the outer surfaces of two groups of sliding plates 5 are respectively fixedly installed with first protective shell 6 and second protective shell 7, and the side of first protective shell 6 is provided with clamping groove 611, and the outer surface of the side of second protective shell 7 is fixedly installed with clamping block 711.

[0026] Further, the moving mechanism comprises two groups of fixed seats 912, which are both fixedly installed in the recess on one side of the mounting rack 3, and the outer surfaces of the two groups of fixed seats 912 are both provided with circular through grooves, and the two-way screw rods 911 are both movably installed in the circular through grooves, one end of the two-way screw rod 911 is connected with the motor 913, and the outer surface of the two-way screw rod 911 movably installs two groups of sliding seats 914, one side of the two groups of sliding seats 914 is connected with the sliding plates 5, and the motor 913 drives the two-way screw rod 911 to rotate in the circular through groove. Due to the special design of the two-way screw rod 911, the rotation will drive the two ends of the sliding seat 914 to relatively move along the direction of the screw rod, that is, to approach each other. With the movement of the sliding seat 914, it drives the sliding plate 5 to move synchronously through the connecting structure. The two groups of sliding plates 5 are respectively fixedly installed with the first protective shell 6 and the second protective shell 7. Therefore, under the movement of the sliding plate 5, the first protective shell 6 and the second protective shell 7 gradually approach and finally merge.

[0027] Further, the motor 913 is fixedly connected with the fixed seat 912, and the fixed connection ensures the stability of the motor 913 in the working process.

[0028] Further, the inner wall of the recess on one side of the mounting rack 3 is fixedly installed with the protective plate 8, and the outer surface of the protective plate 8 is provided with a sliding groove, and the protective plate 8 is movably clamped in the sliding groove. The sliding groove on the protective plate 8 provides guidance and support for the movement of the sliding plate 5, ensuring the stability and accuracy of the sliding process.

[0029] Further, the two sides of the mounting rack 3 are both fixedly installed with the reinforcing rods 4, which enhance the stability and durability of the whole structure.

[0030] Further, the outer surface of the clamping block 711 is wrapped with rubber, which not only increases the tightness of clamping, but also reduces wear and noise to a certain extent.

[0031] Further, the outer end of the mounting rack 3 is arc-shaped, which prevents scratching and increases safety.

[0032] Working principle: when the soot blowing pipe 2 on the soot blower main body 1 completes the soot blowing task and is in an idle state, in order to effectively protect it, first start the motor 913 in the moving mechanism. The motor 913 is fixedly connected with the fixed seat 912, which ensures its stability in the working process. The motor 913 drives the two-way screw rod 911 to rotate in the circular through groove. Due to the special design of the two-way screw rod 911, the rotation will drive the two ends of the sliding seat 914 to relatively move along the direction of the screw rod, that is, to approach each other.

[0033] With the movement of the sliding seats 914, they drive the sliding plates 5 to move synchronously through the connecting structure. The two groups of sliding plates 5 are respectively fixedly installed with the first protective shell 6 and the second protective shell 7. Therefore, under the movement of the sliding plates 5, the first protective shell 6 and the second protective shell 7 gradually approach and finally merge.

[0034] During the merging process, the clamping grooves 611 on one side of the first protective shell 6 and the clamping blocks 711 on one side of the second protective shell 7 are mutually clamped. The outer surface of the clamping block 711 is wrapped with rubber, which not only can increase the tightness of clamping, but also can reduce wear and noise to a certain extent. When the clamping grooves 611 and the clamping blocks 711 are completely clamped, the first protective shell 6 and the second protective shell 7 form a closed protective space, which completely wraps the soot blowing pipe 2, thereby effectively preventing it from being polluted, damaged or accidentally touched by the external environment.

[0035] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
