Description

Technical Field

[0001] The utility model relates to a thistle wire connecting device, belonging to the technical field of dust removal equipment. Background Art

[0002] As an important branch of the environmental protection equipment industry, the dust removal equipment manufacturing industry has attracted much attention in terms of its technological development, especially in the context of China's increasing emphasis on air quality. At present, in the Chinese dust removal equipment industry, the dust removal equipment products are mainly electrostatic precipitators and bag filters. Among them, the electrostatic precipitator has a higher market share, while the bag filter has a lower market share. With the gradual popularization of the electric-bag composite dust collector and the continuous increase in its market share, the application of electrostatic precipitation has more advantages.

[0003] The thistle wires of the cathode system of the existing electrostatic dust removal equipment are mainly connected to the cathode frame in the form of bolts, and the normal heteropolar distance in the electric field is about 150 - 250 mm. At present, the transformation of existing electrostatic precipitators generally has a tight construction period and requires the replacement of thistle wires. Due to the narrow space inside the electric field, after the original thistle wire connecting plate is cut off, a new connecting plate needs to be welded, and the thistle wire needs to be installed. To a certain extent, it will affect the welding and the installation length of the thistle wire. At the same time, it may affect the discharge effect of the thistle wire, and the number of bolt fasteners is large. After being positioned and locked, spot welding is still required, and the process is relatively complex.

[0004] A cathode frame for electrostatic dust removal disclosed in the Chinese utility model patent with the publication number CN207996747U includes a top ring pipe, a middle ring pipe, and a bottom ring pipe. A plurality of first thistle wires are evenly arranged between the top ring pipe and the middle ring pipe, and a plurality of second thistle wires are evenly arranged between the middle ring pipe and the bottom ring pipe. Among them, the first thistle wires are fixedly connected to the top ring pipe and the middle ring pipe by detachable bolts, and the second thistle wires are fixedly connected to the middle ring pipe and the bottom ring pipe by detachable bolts.

[0005] In the above reference example, the thistle wires and the ring pipes are connected by a plurality of detachable bolts. However, the number of bolt fasteners is large, and spot welding is still required after being positioned and locked. The process is relatively complex and requires a long construction period. Therefore, improvement is urgently needed. Content of the Utility Model

[0006] In order to overcome the above-mentioned disadvantages in the prior art, the utility model designs a thistle wire connecting device, which is easy to operate, has a high loading and unloading efficiency, can effectively save labor hours, and save the transformation cost.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A barbed wire connection device includes a barbed wire main body, and also includes an internal thread sleeve fixedly sleeved inside the barbed wire main body. Both ends of the internal thread sleeve are threadedly sleeved with threaded connecting rods. The free end of one of the threaded connecting rods extends out of the barbed wire main body and is threadedly sleeved with a screw buckle, and the free end of the screw buckle is threadedly sleeved with a first hook portion; the free end of the other threaded connecting rod is detachably connected with a second hook portion.

[0009] Further, the threaded connecting rod includes a first threaded rod, a frustum shaft and a second threaded rod which are integrally arranged. The first threaded rod is sleeved in cooperation with the threaded hole of the screw buckle, the second threaded rod extends into the barbed wire main body and is sleeved in cooperation with the threaded hole of the internal thread sleeve, and the frustum shaft is integrally connected between the first threaded rod and the second threaded rod.

[0010] Further, a pair of symmetrically arranged receiving grooves are formed on the side surface of the screw buckle close to the threaded connecting rod, and a pushing and rotating mechanism is arranged in the receiving groove. The pushing and rotating mechanism includes a rotatable handle that can be unfolded.

[0011] Further, the rotatable handle includes a rotating vertical plate and a flexible horizontal plate which are perpendicular to each other and integrally arranged. One end of the rotating vertical plate is rotatably installed in the receiving groove through a rotating shaft, the other end of the rotating vertical plate extends out of the receiving groove and is vertically connected to the flexible horizontal plate, and an arc-shaped socket groove is arranged at the free end of the flexible horizontal plate; the two flexible horizontal plates on both sides of the first threaded rod are butted against each other and sleeved outside the first threaded rod.

[0012] Further, the second hook portion is threadedly connected with the threaded connecting rod through a screw buckle.

[0013] Further, the second hook portion is threadedly sleeved with the threaded connecting rod.

[0014] Compared with the prior art, the present utility model has the following characteristics and beneficial effects:

[0015] 1. By sequentially threadedly connecting the barbed wire main body with the threaded connecting rod, the screw buckle and the first hook portion, the present utility model can effectively improve the installation and assembly speed, without the need to install and fasten with multiple bolts, avoiding the problem of long construction period caused by a large number of bolt fasteners and the need for spot welding after the bolt fasteners are tightened. At the same time, when the barbed wire main body needs to be replaced during equipment transformation, the screw buckle can be directly removed, further saving the construction period.

[0016] 2. The utility model can unfold the two rotating handles when rotating the turnbuckle by setting the push-turn mechanism, and then the turnbuckle can be rotated by turning the rotating handle, which is more labor-saving and improves the convenience of operation. At the same time, by connecting the two flexible horizontal plates on both sides of the first threaded rod and sleeved outside the first threaded rod, a flexible protection can be formed between the turnbuckle and the threaded connecting rod to prevent the damage of the components caused by the rigid collision between the turnbuckle and the threaded connecting rod, thereby ensuring the stability of the connection structure between the turnbuckle and the threaded connecting rod.
