Description

Technical Field

[0001] This utility model relates to the field of antifreeze equipment technology, specifically to an antifreeze device for heating pipe networks. Background Technology

[0002] During winter operation, the water in heating pipe networks is prone to freezing due to low temperatures, which can clog the pipes and affect the normal operation of the heating system. While existing antifreeze devices for heating pipe networks can provide some protection against freezing, several problems still exist.

[0003] Publication No. CN220250136U discloses a heating pipeline antifreeze device, including a first antifreeze sleeve and a second antifreeze sleeve. The first antifreeze sleeve is located above the second antifreeze sleeve, and both the first and second antifreeze sleeves have a heat-insulating coating on one inner wall. A first connecting half-ring and a second connecting half-ring are respectively provided on one outer wall of both the first and second antifreeze sleeves, with the first connecting half-ring located to one side of the second connecting half-ring. A connecting plate is provided on one outer wall of both the first and second antifreeze sleeves near the position between the first and second connecting half-rings. This heating pipeline antifreeze device, through the connection of the first connecting half-ring, the second connecting half-ring, and the connecting plate, allows for convenient assembly and installation of the first and second antifreeze sleeves, as well as the installation and fixing of adjacent first and second antifreeze sleeves. It provides all-round protection against freezing of the heating pipeline and facilitates the disassembly and assembly of the antifreeze device. However, the existing technology still has drawbacks:

[0004] Existing antifreeze devices for heating networks typically require bolts to secure various components together during installation. While this method ensures stability, the large number and locations of bolts make the installation process cumbersome, consuming significant time and manpower. This is especially problematic during maintenance or replacement of the heating network, where frequent disassembly and reassembly further complicate bolt installation and removal, impacting work efficiency. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a heating pipe network antifreeze device, comprising:

[0007] The lower protective sleeve has a fixing plate fixedly connected to the upper part of both the front and rear ends of the lower protective sleeve. The fixing plate has connecting grooves on both sides of its upper end.

[0008] The upper protective cover is set on the upper end of the lower protective cover. The lower ends of the front and rear ends of the upper protective cover are fixedly connected to the second fixing plate. The upper end of the second fixing plate is provided with an installation hole, which passes through the first fixing plate and the second fixing plate.

[0009] A connecting block is inserted into the connecting groove and is fixedly connected to both sides of the lower end of the fixing plate. The connecting block is L-shaped, and a sliding groove is provided at the lower end of the connecting groove and on one side of the connecting block.

[0010] A spring telescopic rod, which is fixedly connected to both sides of the lower end of the lower protective sleeve and both sides of the upper end of the upper protective sleeve;

[0011] A heat pipe is disposed on one side of the lower protective sleeve and the upper protective sleeve that are close to each other;

[0012] The clamp is disposed at the upper and lower ends of the heating pipe and is fixedly connected to one end of the spring telescopic rod;

[0013] A support frame is fixedly connected to both sides of the lower end of the lower protective sleeve.

[0014] As an improvement, both the lower protective sleeve and the upper protective sleeve are provided with heat insulation layers.

[0015] As an improvement, both clamps are fixedly connected to an electric heating plate on one side close to each other.

[0016] As an improvement, the fixing plate one and fixing plate two are fixed to the lower protective sleeve and the upper protective sleeve by inserting bolts inside the mounting holes.

[0017] The advantages of this invention compared to existing technologies are as follows: The heating network antifreeze device of this invention achieves rapid connection and fixation between the lower and upper protective sleeves through a structure including a connecting groove, connecting block, and sliding groove. During installation, simply insert the connecting block into the connecting groove and then easily and effortlessly connect it via the sliding groove to temporarily fix the lower and upper protective sleeves. Then, bolts are installed inside the mounting holes to further securely fix the lower and upper protective sleeves together.

The connecting groove 12 is opened on both sides of the upper end of the fixing plate 11. The upper protective sleeve 2 is installed on the upper end of the lower protective sleeve 1. The upper protective sleeve 2 is installed at the lower end of the front and rear ends of the lower protective sleeve 1. Fixed plates 21 are fixedly connected to both ends. Mounting holes 22 are opened at the upper end of fixed plate 21, penetrating both fixed plate 11 and fixed plate 21. Connecting blocks 3 are inserted into connecting grooves 12 and are fixedly connected to both sides of the lower end of fixed plate 21. Connecting blocks 3 are L-shaped. Sliding grooves 31 are opened at the lower end of connecting grooves 12 and on one side of connecting blocks 3. Spring telescopic rods 4 are fixedly connected to both sides of the lower end of the lower protective sleeve 1 and both sides of the upper end of the upper protective sleeve 2. Heat pipes 5 are installed... The lower protective sleeve 1 and the upper protective sleeve 2 are close to each other on one side. The clamping plate 6 is installed at the upper and lower ends of the heat pipe 5. The clamping plate 6 is fixedly connected to one end of the spring telescopic rod 4. The support frame 7 is fixedly connected to both sides of the lower end of the lower protective sleeve 1.

Then the upper protective sleeve 2 is placed on the upper end of the lower protective sleeve 1. The fixing plate 11 and the fixing plate 21 are attached. At this time, the connecting block 3 is placed inside the connecting groove 12. Then the upper protective sleeve 2 is pushed, which drives the connecting block 3 to be inserted into the connecting groove 12. The connecting block 3 is conveniently and effortlessly inserted through the sliding groove 31. After the lower protective sleeve 1 and the upper protective sleeve 2 are temporarily fixed by the connecting block 3, the lower protective sleeve 1 and the upper protective sleeve 2 are stably fixed by installing bolts inside the mounting hole 22. When the lower protective sleeve 1 and the upper protective sleeve 2 are fixed, the clamping plate 6 is pushed to the outside of the heat pipe 5 by the elastic force of the spring telescopic rod 4.

[0027] Both the lower protective sleeve 1 and the upper protective sleeve 2 are equipped with heat insulation layers 8, which provide heat insulation.

[0028] Two clamps 6 are fixedly connected to an electric heating plate 9 on one side of each other. The electric heating plate 9 heats the heat pipe 5 to prevent it from freezing.

[0030] In use, after placing the lower protective sleeve 1 outside the heat pipe 5, the lower protective sleeve 1 is fixed by fixing the support frame 7 with bolts. Then, the upper protective sleeve 2 is placed on the upper end of the lower protective sleeve 1, and the fixing plate 11 and the fixing plate 21 are attached. At this time, the connecting block 3 is placed inside the connecting groove 12. Then, the upper protective sleeve 2 is pushed, which drives the connecting block 3 to be inserted into the connecting groove 12. The connecting block 3 is conveniently and effortlessly inserted through the sliding groove 31. After the lower protective sleeve 1 and the upper protective sleeve 2 are temporarily fixed by the connecting block 3, the lower protective sleeve 1 and the upper protective sleeve 2 are stably fixed by installing bolts inside the mounting hole 22. When fixing the lower protective sleeve 1 and the upper protective sleeve 2, the spring force of the spring telescopic rod 4 pushes the clamp 6 to be attached to the outside of the heat pipe 5.
