Description

Technical Field

[0001] The utility model belongs to the technical field of water pipe insulation in winter, in particular to a watering pipe heating and insulation device. Background Art

[0002] In the cold winter environment, the normal operation of sprinkler pipes plays a vital role in fire emergency, environmental protection, farmland irrigation, etc. Sprinkler pipes that freeze and crack in winter will cause the pipes to be blocked, and the water in the pipes cannot be transported normally, which will cause the corresponding sprinkler equipment to fail. To address this type of problem, based on current existing technologies, it is generally adopted to install heating tape and insulation layer on the outer wall of the sprinkler pipe to prevent the pipe from freezing, cracking or leaking due to low temperature. The main process flow is: laying or wrapping the heating tape on the outer wall of the entire sprinkler pipe, and installing temperature sensors at appropriate locations, and then wrapping the insulation layer on the sprinkler pipe equipped with the heating tape and temperature sensor. Finally, an aluminum protective layer is installed on the wrapped insulation layer to enhance the insulation effect and improve the moisture and corrosion resistance of the insulation layer.

[0003] The installation process for adding heating cables, insulation, and aluminum protective layers to sprinkler pipes is relatively simple, but the installation time is long, especially if the sprinkler pipes are located at a high location. Furthermore, if the sprinkler pipes are too long, the temperature sensor installation position can be difficult to determine. If the temperature sensor is installed far from the temperature control box, the temperature it detects will be the temperature at the far end of the sprinkler pipe, increasing the heating time of the heating cables and energy consumption. If the temperature sensor is installed close to the temperature control box, the temperature it detects will be the temperature at the near end of the pipe. The heating time of the sprinkler pipe from the far end to the temperature sensor may be shorter, failing to reach the required temperature, and thus causing freezing.

[0004] In addition, when the heating cable, temperature sensor or insulation layer of the sprinkler pipe is damaged, the aluminum protective layer and insulation layer of the damaged part need to be destroyed and reinstalled after the repair is completed. The entire repair process is difficult and time-consuming, and the quality of the repair is difficult to guarantee. Utility Model Content

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a watering pipe heating and insulation device to overcome the problems raised in the above-mentioned background technology.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] 18. The heat insulation device of claim 17, wherein the heat insulation module comprises a heat insulation box, a box cover, a box body insulation layer, a box cover insulation layer, a silicone heating sheet, a temperature sensor and a box body connecting ear. A line cavity and a pipe cavity are sequentially arranged in the heat insulation box from bottom to top. A line outlet is arranged on the heat insulation box at a position corresponding to the line cavity. A silicone heating sheet is laid at the bottom of the pipe cavity. A box body insulation layer is installed in the pipe cavity above the silicone heating sheet. A watering pipe mounting groove is provided on the box insulation layer. A temperature sensor is provided on each watering pipe mounting groove. A box cover is installed on the top of the heat insulation box. A box cover insulation layer is provided inside the box cover. Pipeline insertion ports are opened at positions corresponding to the watering pipe mounting grooves at front and rear ends of the heat insulation box. Box body connecting ears are provided at both ends of the front and rear ends of the heat insulation box. Each heating and heat insulation module is connected by cooperation between the box connecting ears and the screws.

[0008] Moreover, the heat-insulating layer of the box cover is a structure in which a raised portion is provided corresponding to the position of the installation groove of the sprinkler pipe, and the raised portion is embedded in the installation groove of the sprinkler pipe.

[0009] In addition, it also includes a fixed bracket and a fixed baffle. The fixed bracket is composed of a vertical beam, a horizontal beam and a reinforcing angle steel. A horizontal beam extending horizontally to one side is provided on the top of the vertical beam, and a reinforcing angle steel is provided at the angle between the horizontal beam and the vertical beam. The heating and insulation module is placed on the horizontal beam, and fixed baffles are welded to the horizontal beams at both ends of the heating and insulation module.

[0010] Moreover, the thermal insulation box is made of glass fiber reinforced plastics.

[0011] The advantages and positive effects of the utility model are:

[0012] This sprinkler pipe heating and insulation device only requires the insulation box and cover of the heating and insulation module to be snapped onto the sprinkler pipe and secured during maintenance. Multiple heating and insulation modules can be connected to achieve full coverage of the sprinkler pipe heating and insulation system fixed to the equipment. The silicone heating plate and temperature sensor of the heating and insulation module can be connected to the temperature monitoring device in the temperature control box. The temperature monitoring device can be used to control the temperatures of multiple heating and insulation modules separately, effectively saving energy and improving energy efficiency. At the same time, the temperature monitoring device can accurately locate faulty heating and insulation modules in a timely manner. This significantly improves the efficiency and quality of sprinkler pipe heating and insulation maintenance while ensuring the safe use of the sprinkler pipe heating and insulation modules.
