[0002] The weight level meter is a material level meter used to measure the height of materials in a cylindrical silo. The weight level meter is mainly composed of a weight, a steel wire, a steel wire retracting and releasing mechanism, and related sensors. During measurement, the weight drives the steel wire to fall, and the sensor measures the falling distance, thereby obtaining the distance from the material surface to the material level meter. After the measurement is completed, the weight and steel wire need to be retracted through the retracting and releasing mechanism to facilitate the next measurement.

[0003] A heavy hammer level meter is disclosed in the patent with publication number CN215573193U. During the process of winding the steel wire on the reel, the steel wire is tangled on the reel in a disorderly manner, which reduces the amount of steel wire that the reel can accommodate, and may cause the steel wire to be tangled and unable to be released and completely wound.

[0035] Specifically, a tensioning wheel 2 is arranged between the reel 12 and the guide wheel 13 so that the tensioning wheel 2 supports the steel wire 14 between the reel 12 and the guide wheel 13, and a support shaft 3 is arranged so that the tensioning wheel 2 can slide axially.

[0036] In this way, during the winding process, the tensioning of the steel wire 14 causes it to be arranged in an axial spiral along the reel 12 when it is wound on the reel 12. By providing an axially movable tensioning wheel 2, the axial spiral winding of the steel wire 14 is facilitated, and the steel wire 14 is arranged tightly and regularly, thereby reducing the problem of the steel wire 14 being entangled and the actual capacity of the reel 12 being reduced due to winding in one position.

[0037] In some feasible modes, the main body 1 is a prior art and will not be described in detail here. The tension wheel 2 is an I-shaped wheel, the wire groove 4 is a semicircular groove adapted to the radius of the steel wire 14, and the support shaft 3 is a cylindrical shaft.

[0038] As a specific implementation of a heavy hammer level meter with an anti-winding structure provided in the application, please refer to Figure 2-Figure 3 A reversing mechanism is provided at the support shaft 3, and the reversing mechanism includes a central hole 51 that penetrates the support shaft 3 axially, a sliding body 52 is slidably installed on the outer side of the support shaft 3, and the tensioning wheel 2 is rotatably installed on the outer side of the sliding body 52. ​​A reciprocating torque ring 53 is slidably installed on the shell 11, and two racks 531 are symmetrically arranged on the inner side of the reciprocating torque ring 53. A driving half gear 54 is rotatably installed on the shell 11 at the center of the reciprocating torque ring 53, and the driving half gear 54 is provided with half a circle of gear teeth. The rotating shaft of the reel 12 is connected with a reduction gear set 55, and the output end of the reduction gear set 55 is connected to the driving half gear 54. The reciprocating torque ring 53 is fixedly connected with a driving flexible shaft 56, and the other end of the driving flexible shaft 56 is slidably installed in the central hole 51, and one end of the driving flexible shaft 56 located in the central hole 51 is fixedly connected to the sliding body 52. ​​A sliding groove is provided on the side wall of the support shaft 3, and the sliding groove is used for sliding the connection position of the driving flexible shaft 56 and the sliding body 52.

[0039] In general, by setting the reciprocating moment ring 53 and the driving half gear 54, when the driving half gear 54 rotates, the half-circle gear and the racks 531 on both sides of the reciprocating moment ring 53 are alternately meshed, so that the reciprocating moment ring 53 slides back and forth, thereby driving the driving soft shaft 56 to slide back and forth axially in the center hole 51, thereby causing the tensioning wheel 2 to slide back and forth axially. At the same time, the reversing mechanism is connected to the rotating shaft of the reel 12 through the reduction gear set 55, so that when the reel 12 rotates, it drives the reversing mechanism to operate, thereby driving the tensioning wheel 2 to slide back and forth axially, and assisting the spiral reciprocating winding of the steel wire 14.

[0040] In some feasible embodiments, the sliding body 52 is in the shape of a circular ring, and two rectangular blocks arranged in mirror symmetry are fixedly connected to the inner side of the sliding body 52. ​​The rectangular blocks are connected to the driving flexible shaft 56 through the sliding groove. The driving flexible shaft 56 can be selected as a steel wire rope or other soft material that can provide axial support force. The reduction gear set 55 connects the reel 12 and the driving half gear 54 to transmit power and make the reel 12 and the driving half gear 54 move synchronously. The reduction gear set 55 can be selected as a gear belt, a gear set and other transmission mechanisms to match the rotation speed of the reel 12 with the sliding speed of the sliding body 52.

[0041] Furthermore, an L-shaped tube 561 is fixedly mounted on one end of the support shaft 3 close to the reciprocating moment ring 53 , and the driving flexible shaft 56 is installed in the L-shaped tube 561 .

[0042] It should be understood that by providing the L-shaped tube 561 , the bending position of the driving flexible shaft 56 is located inside the L-shaped tube 561 , thereby reducing the situation in which the sliding body 52 fails to slide into place due to the change in the bending degree of the driving flexible shaft 56 during movement.

[0043] As another specific implementation of the heavy hammer level meter with anti-winding structure provided by the application, please refer to Figure 1 The housing 11 includes a mounting shell and a cover plate, the mounting shell and the cover plate are connected with bolts, a sealing ring groove is arranged on the outer side of the mounting shell close to the cover plate, and the cover plate is sleeved in the sealing ring groove.

[0044] In view of the specific usage scenario, the level meter is mostly used in a silo with a lot of dust. If too much dust enters the shell 11, it will also cause poor winding of the steel wire 14. By setting a sealing ring groove, the end of the cover plate is located in the sealing ring groove, and it is tightened by bolts to form a seal, thereby reducing the entry of dust.

[0045] In some feasible ways, the sealing ring groove is opened on the side of the mounting shell close to the cover plate, so that the outer side of the mounting shell on this side is stepped. The mounting shell is a rectangular shell, and the first connecting holes 111 are set at the top corners of the mounting shell. Two second connecting holes 112 are set on the long sides of the mounting shell. The first connecting holes 111 are located on the inner side of the sealing ring groove, and the second connecting holes 112 are located at the bottom of the sealing ring groove. By setting the first connecting holes 111 and the second connecting holes 112 to fasten from two positions, the inner side of the sealing ring groove and the bottom of the groove, the contact gap between the end of the cover plate and the bottom of the sealing ring groove is reduced, thereby better preventing dust.

[0046] In some feasible embodiments, a sealing ring may be provided at the bottom of the sealing ring groove.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
