Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to an antifreeze device for outdoor water conservancy and hydropower equipment. Background Technology

[0002] Valves are mainly used to regulate, control, and cut off water flow, playing a vital role in water conservancy and hydropower systems, such as reservoirs, canals, pumping stations, water pipelines, and power plants. Valves can effectively control the flow of water and ensure the normal operation of the system.

[0003] There are many types of existing antifreeze devices for outdoor water conservancy and hydropower equipment. For example, the antifreeze device for outdoor water conservancy and hydropower equipment disclosed in patent publication number CN222527990U has a heat pump heating and electric auxiliary heating structure. It has low energy consumption when heating for antifreeze. However, when taking antifreeze measures for water conservancy and hydropower equipment such as valves, the process of increasing the temperature for antifreeze will affect the water source transported inside the water pump. If the water source is overheated, the pressure of the transport will increase, which will lead to the instability of the entire water supply system or damage to the sealing performance of the valve. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an antifreeze device for outdoor water conservancy and hydropower equipment, which can effectively solve the problem that the water supply system becomes unstable during the antifreeze heating process in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an antifreeze device for outdoor equipment in water conservancy and hydropower projects, comprising:

[0007] A protective box, wherein a sealing cover is fixedly installed on the upper end face of the protective box, a temperature difference detection element is embedded in the outer wall of the protective box, a water pump is fixedly installed inside the protective box, and water pipes are fixedly installed at both the input and output ends of the water pump, the water pipes extending through the protective box to the outside.

[0008] A heating component, comprising a first semiconductor fixedly installed inside a protective box, a flow tube disposed above the protective box, a plurality of first exhaust holes symmetrically opened on the outer wall of the flow tube near the upper end face of the protective box, and a plurality of second exhaust holes opened on the outer wall of the flow tube near the first semiconductor.

[0009] A cooling assembly, comprising a cooling box fixed to one side of a protective box, a second semiconductor fixedly installed inside the cooling box, and an outer connecting pipe fixedly installed on the outer wall of the water pipe;

[0011] Preferably, a conveying hose is connected to one side of the protective box, a fan is fixedly installed inside the conveying hose, the fan is electrically connected to the controller, and the upper end of the conveying hose is connected to the flow pipe.

[0012] Preferably, a flow shroud is connected inside the conveying hose and above the fan. A rotating rod is rotatably installed on the inner wall of the flow shroud. A short shaft is fixedly installed at one end of the rotating rod, and a plurality of first fan blades are fixedly installed in a circumferential array on the outer wall of the short shaft.

[0013] Preferably, fixing rings are fixedly installed on both sides of the protective box, and the fixing rings are fixedly connected to the outer wall of the flow pipe.

[0014] Preferably, one end of the rotating rod passes through the cooling box and extends into the interior.

[0015] Preferably, the inner circumferential array of the outer pipe has flow holes, one end of which is connected to an air inlet hood, and the lower end of the air outlet pipe is connected to the air inlet hood.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] 1. The temperature difference between the inside and outside is monitored in real time by the temperature difference detection element, and the operation of the heating and cooling components is adjusted by the controller. The appropriate temperature inside the protection box is maintained in the low temperature environment, which effectively prevents the outside of the equipment from freezing and the inside of the water source from overheating. The heating airflow is evenly discharged through the flow pipe to avoid condensation and ice formation on the surface of the box. At the same time, the cooling component uses the cooling characteristics of semiconductors to dissipate heat from the water pipes, ensuring that the temperature of the delivered water source is stable. This solves the problem of system pressure fluctuation and valve sealing performance damage caused by water temperature rise in traditional antifreeze devices.

[0018] 2. It adopts semiconductor bidirectional thermal management technology, integrating heating and cooling functions into the same circuit, significantly reducing energy consumption; through the linkage design of the fan and blades, it realizes the circulation of heating airflow and the active delivery of cooling airflow, improving thermal energy utilization efficiency. In addition, the mechanical structure is simplified and reliable, such as the transmission design of the fan blades and rotating rod, which reduces the additional power requirements and lowers maintenance costs, making it suitable for the long-term stable antifreeze requirements of outdoor water conservancy and hydropower equipment.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4 An antifreeze device for outdoor water conservancy and hydropower equipment, comprising:

[0028] The protective box 1 has a sealing cover 101 fixedly installed on its upper end face. The outer wall of the protective box 1 is embedded with a temperature difference detection element. The inside of the protective box 1 is fixedly installed with a water pump 2. The input and output ends of the water pump 2 are both fixedly installed with water pipes 201. The water pipes 201 pass through the protective box 1 and extend to the outside.

[0029] The heating component 3 includes a first semiconductor 301 fixedly installed inside the protective box 1. A flow pipe 303 is provided above the protective box 1. Multiple first exhaust holes 304 are symmetrically opened on the outer wall of the flow pipe 303 near the upper end face of the protective box 1. Multiple second exhaust holes 305 are opened on the outer wall of the flow pipe 303 near the first semiconductor 301.

[0030] Cooling assembly 4 includes a cooling box 401 fixed to one side of the protective box 1, a second semiconductor is fixedly installed inside the cooling box 401, and an outer pipe 406 is fixedly installed on the outer wall of the water pipe 201.

[0031] The first semiconductor 301 and the second semiconductor are connected in series by a wire to form a power-carrying circuit, and the power-carrying circuit is connected to a controller.

[0032] A conveying hose 306 is connected to one side of the protective box 1. A fan 307 is fixedly installed inside the conveying hose 306. The fan 307 is electrically connected to the controller. The upper end of the conveying hose 306 is connected to the flow pipe 303.

[0033] A flow cover 308 is connected inside the conveying hose 306 and above the fan 307. A rotating rod 309 is rotatably installed on the inner wall of the flow cover 308. A short shaft 310 is fixedly installed at one end of the rotating rod 309. Multiple first fan blades 311 are fixedly installed in a circumferential array on the outer wall of the short shaft 310.

[0034] The protective box 1 is fixedly installed with fixing rings 302 on both sides, and the fixing rings 302 are fixedly connected to the outer wall of the flow pipe 303.

[0035] One end of the rotating rod 309 passes through the cooling box 401 and extends into the interior. Multiple second fan blades 402 are fixedly installed on the outer wall of the rotating rod 309 and in a circumferential array inside the cooling box 401. An exhaust hood 403 is connected to one side of the cooling box 401, and an air outlet pipe 404 is connected to one side of the exhaust hood 403.

[0036] The inner circumferential array of the outer pipe 406 has flow holes 407, one end of which is connected to the air inlet hood 405, and the lower end of the air outlet pipe 404 is connected to the air inlet hood 405.

[0037] The working principle of this utility model is as follows:

[0038] The controller supplies power to the circuit, causing the first semiconductor 301 to heat up and the second semiconductor to absorb heat. When the first semiconductor 301 is heated, it increases the temperature inside the protection box 1, thus maintaining a suitable temperature inside the protection box 1. When the outside temperature drops and a temperature difference occurs between the outside and inside the protection box 1, the temperature difference detection element generates a corresponding electrical signal based on the temperature difference. The controller controls the current input to the fan 307 through the generated electrical signal, causing the fan 307 to start and draw out the heated air inside the protection box 1 and deliver it into the flow pipe 303. The air is then sprayed from the first exhaust port 304 and the second exhaust port 305 onto the outer side of the protection box 1. This effectively prevents water droplets from adhering to the outer wall of the protection box 1 due to the large temperature difference between the inside and outside of the protection box 1. In low-temperature environments, although the inside of the protection box 1 can maintain its temperature and avoid freezing due to the influence of the outside temperature, the outside air, when the humidity is high, will form water droplets due to the temperature difference and adhere to the outer side of the protection box 1. As the temperature continues to drop, the water droplets will freeze, which is not conducive to personnel observing the operation of the water pump 2.

[0039] As the heated air flows through the delivery hose 306, it enters the flow cover 308 and drives the first fan blade 311 and the short shaft 310 to rotate. This causes the short shaft 310 to drive the rotating rod 309 to rotate. During the rotation of the rotating rod 309, the air inside the cooling box 401, which has been cooled by the second semiconductor, flows into the exhaust cover 403 and the air outlet pipe 404. Finally, it enters the air inlet cover 405 and flows into the flow hole 407, cooling the external pipe 406. This effectively prevents the water pump 2 from heating inside the protection box 1, which could cause temperature differences in the delivered water source and negatively affect valves and other equipment. For example, increased water temperature could increase pressure, leading to system instability or damage to the valve's sealing performance.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
