Description

Technical Field

[0001] This utility model relates to the field of de-icing technology for drainage pipes, and in particular to a heating de-icing device for drainage pipe maintenance. Background Technology

[0002] Drainage pipes are infrastructure that can transport wastewater, rainwater or other liquids, discharging wastewater from buildings, roads or other areas into sewage treatment facilities or natural water bodies. They are an important part of urban and building drainage systems.

[0003] During operation, when the water temperature inside the drainage pipe drops below freezing in low-temperature environments, especially in extremely low temperatures or when the pipe is exposed, ice can easily form inside the drainage pipe, requiring de-icing work. However, frozen drainage pipes are inconvenient to remove from the pipeline system, forcing workers to de-ice the pipes by localized heating of the outer wall. This method results in a small heating area and poor de-icing effect. Therefore, we propose a heating de-icing device for drainage pipe maintenance. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1-4 The heating and de-icing device for drainage pipe maintenance shown includes a semi-ring pipe 101, a heating mechanism, a connecting mechanism, and a positioning mechanism. The semi-ring pipe 101 is arranged in a semi-ring shape. The heating mechanism is located inside the semi-ring pipe 101. The connecting mechanism is located between the two semi-ring pipes 101. The positioning mechanism is located between the two semi-ring pipes 101. The positioning mechanism is used to fix the semi-ring pipe 101 to the outer wall of the pipe. By setting the semi-ring pipe 101 as a semi-ring, the two semi-ring pipes 101 can be combined into a ring and placed on the outer wall of the pipe. Then, the heating mechanism heats and de-ices the pipe. At this time, the pipe can be heated in a ring without disassembling the pipe, which increases the heating area of ​​the pipe and thus improves the de-icing effect.

[0031] The connecting mechanism includes a connecting ring 201 and a rotating rod 203. A first connecting rod 202 is fixedly connected to the outer wall of the connecting ring 201. One end of the first connecting rod 202 is fixedly connected to the outer wall of one of the semi-ring pipes 101. The rotating rod 203 is rotatably connected between the two connecting rings 201. A second connecting rod 204 is fixedly connected to the outer wall of the rotating rod 203. One end of the second connecting rod 204 is fixedly connected to the outer wall of the other semi-ring pipe 101. By rotating the rotating rod 203 between the two connecting rings 201 and then connecting the first connecting rod 202 and the second connecting rod 204, the two semi-ring pipes 101 can rotate relative to each other. This makes it convenient to fit the two semi-ring pipes 101 onto or remove them from the outer wall of the drainage pipe, thereby improving the ease of use of the de-icing device.

[0032] One of the semi-circular tubes 101 has a first fixing block 301 fixedly connected to its outer wall, and a second fixing block 302 fixedly connected to one side of the first fixing block 301. The other semi-circular tube 101 has a third fixing block 303 fixedly connected to its outer wall. A positioning mechanism is disposed between the second fixing block 302 and the third fixing block 303. The positioning mechanism includes a positioning rod 403. The bottom end of the second fixing block 302 has a movable hole 402. The outer wall of the positioning rod 403 is movably inserted into the inner wall of the movable hole 402. The top end of the third fixing block 303 has a positioning... The outer wall of the positioning rod 403 is movably connected to the inner wall of the positioning hole 401. The top of the positioning rod 403 is provided with a pressing member. The two semi-ring tubes 101 are rotated to form a ring that fits onto the outer wall of the drainage pipe. Then, the positioning rod 403 is inserted from the movable hole 402 and inserted into the positioning hole 401, which fixes the second fixing block 302 and the third fixing block 303, thereby fixing the two semi-ring tubes 101. This makes the two semi-ring tubes 101 stably fit onto the outer wall of the drainage pipe, thereby improving the stability of the de-icing device.

[0033] The pressing component includes a spring 404, which is disposed between the top of the positioning rod 403 and the inner wall of the movable hole 402. An operating mechanism is provided on one side of the positioning rod 403. Through the elastic action of the spring 404, the positioning rod 403 always has a downward tendency, so that the positioning rod 403 can be stably inserted into the positioning hole 401, thereby improving the stability of the positioning mechanism.

[0034] The operating mechanism includes a slider 502, which is fixedly connected to one side of the positioning rod 403. A groove 501 is provided on one side of the second fixing block 302. The outer wall of the slider 502 is slidably connected to the inner wall of the groove 501. The slider 502 slides on the inner wall of the groove 501, and the length of the slider 502 is greater than the width of the groove 501, which facilitates movement between the second fixing block 302 and the positioning rod 403, thereby improving the convenience of moving the positioning rod 403.

[0035] The heating mechanism includes a connecting box 601, a heating liquid 602, and a heating wire 603. The connecting box 601 is fixedly connected to the outer wall of the semi-ring pipe 101. The heating liquid 602 is disposed inside the connecting box 601 and the semi-ring pipe 101. The heating wire 603 is installed on the inner wall of the connecting box 601. When the heating wire 603 is energized, the heating liquid 602 in the semi-ring pipe 101 and the connecting box 601 is heated, thereby heating the drainage pipe between the two semi-ring pipes 101 and achieving the effect of de-icing the drainage pipe. The heating wire 603 is electrically connected to an external power source through an external switch, which facilitates the operator's control of the heating wire 603 and improves the safety and convenience of operating the heating wire 603.

[0036] The top of the connecting box 601 is fixedly connected to an inlet pipe 701, and a sealing plug 702 is inserted into the inner wall of the inlet pipe 701. The heating liquid 602 can be conveniently injected into the semi-ring pipe 101 and the connecting box 601 through the inlet pipe 701. The sealing plug 702 seals the inlet pipe 701 to prevent the heating liquid 602 from leaking.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
