A protective device for heating and ventilation pipes

Abstract

The utility model discloses a protective device for a HVAC pipeline, comprising a semicircular hoop frame A, a hinge, a semicircular hoop frame B, a vacuum chamber and a heating pipe, wherein the semicircular hoop frame A and the top of the semicircular hoop frame B are hinged to each other through the hinge. The utility model fixes and hangs the HVAC pipeline between the semicircular hoop frame A and the semicircular hoop frame B. When the outdoor temperature is low, the thermocouple detects that the temperature in the vacuum layer is low, and the thermocouple controls the heating pipe to heat, thereby preventing the HVAC pipeline from cooling due to excessive heat dissipated in the outdoor section due to the low outdoor temperature; the positioning pressure plate can be separated from the support foot by rotating the rotating part, so that the height of the support foot can be adjusted according to the use environment, which not only has a certain stable supporting effect on the HVAC pipeline, but also can adjust the height of the support foot, thereby solving the problem that the existing protective device does not have the function of supporting the HVAC pipeline.

Description

Technical Field

[0001] The utility model relates to the technical field of HVAC pipeline protection, in particular to a HVAC pipeline protection device. Background Art

[0002] The thickness and specifications of the HVAC pipes can be changed according to the requirements. Usually, when connecting, the two ends of the air duct are always connected to the accessories. Generally, there are no grooves at both ends of the HVAC pipes and they are equipped with sealing rings. Usually, the HVAC pipes placed outdoors usually have protective devices to protect the HVAC pipes. The main protective device is a fabric wrapping layer, which mainly prevents the outdoor HVAC pipes from losing heat due to the low outdoor temperature. Among them, the "protective device for HVAC pipes" disclosed in the application number "CN208816915U" has solved the problem of not being able to increase the sealing of the HVAC pipe joints. The invention discloses a kind of HVAC pipe protective device, which has the advantages of sealing property, inability to guide water droplets in the HVAC pipe, and inability to increase the stability of the HVAC pipe. However, in actual use, a corn threshing device with a similar structure still has many defects, such as: the existing HVAC pipe protective device has limited insulation effect, which causes the HVAC pipe to lose too much heat; the existing HVAC pipe protective device does not have a supporting function. When the outdoor section of the HVAC pipe is too long, due to excessive gravity, the HVAC pipe is not sealed tightly at the interface of the outdoor section, resulting in leakage, thereby affecting the use. Therefore, it is necessary to design a HVAC pipe protective device. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides an embodiment: a protective device for a HVAC pipeline, comprising a semicircular hoop frame A1, a hinge 2, a semicircular hoop frame B3, a vacuum chamber 4 and a heating tube 5, wherein the tops of the semicircular hoop frame A1 and the semicircular hoop frame B3 are hinged to each other through the hinge 2, and the interiors of the semicircular hoop frame A1 and the semicircular hoop frame B3 are both provided with a vacuum chamber 4, and the inner wall of the vacuum chamber 4 is evenly fixed with a plurality of identical heating tubes 5, and the inner wall of the heating tube 5 is evenly fixed with a plurality of identical sleeves 6, and the interior of the sleeve 6 A detection end of a thermocouple 7 is fixedly connected, and a plurality of identical support tubes 12 are fixedly connected at equal distances at the bottom of the semicircular hoop frame A1 and the semicircular hoop frame B3, and legs 13 are movably connected inside the support tubes 12, and a threaded end 14 is sleeved on the side wall of the support tube 12, and an adjusting screw 15 is threadedly connected inside the threaded end 14, and a positioning pressure plate 16 is rotatably connected to the adjusting screw 15 at one end placed inside the support tube 12, and a rotating member 17 is fixedly connected to the one end of the adjusting screw 15 placed outside the support tube 12;

[0020] Specifically, the outer wall of the semicircular hoop frame A1 and the outer wall of the semicircular hoop frame B3 are both bonded with a glass wool layer 8;

[0022] Specifically, the support leg 13 at the bottom of the semicircular hoop frame A1 and the support leg 13 at the bottom of the semicircular hoop frame B3 are symmetrically arranged, and the support leg 13 is an "L"-shaped structure;

[0023] Specifically, a fastening hole 18 is formed at the bottom of the support leg 13, and a foundation bolt 19 is movably sleeved on the surface of the fastening hole 18, and a tightening member B20 is threadedly sleeved on the top of the foundation bolt 19;

[0024] Specifically, the thermocouple 7 is electrically connected to a plurality of heating tubes 5 .

[0025] Working principle: remove several fastening screws 10 and tightening pieces A11, put the outdoor HVAC pipe between the semicircular hoop frame A1 and the semicircular hoop frame B3, then install the fastening screws 10 and tightening pieces A11, drive several anchor bolts 19 into the ground, then insert several supporting feet 13 into several supporting tubes 12 respectively, then insert the anchor bolts 19 into the corresponding fastening holes 18, then tighten the tightening piece B20, and finally rotate the rotating piece 17, and drive the adjusting screw 15 to rotate through the rotating piece 17, and drive the positioning pressure plate 16 to move to one side of the supporting foot 13 through the cooperation of the adjusting screw 15 and the threaded end 14, and finally fix the supporting foot 13 through the action of the positioning pressure plate 16 and the supporting tube 12.
