Description

Technical Field

[0001] This utility model relates to the field of water sprinkler truck technology, and in particular to a structure for an antifreeze and heat-insulating water pipe for a water sprinkler truck. Background Technology

[0002] A sprinkler truck, also known as a multi-functional greening sprinkler truck, is used for cleaning roads, sanitation, dust control, watering, and spraying pesticides in urban areas, large factories, military units, gardens, and other units. The sprinkler truck's water pipe structure consists of a delivery pipe and a spray pipe. Pressurized water is sprayed from nozzles on the spray pipe onto the ground, achieving the function of sprinkling water.

[0003] In existing sprinkler trucks, water is sprayed from the water pipe structure by a water pump. However, the existing sprinkler truck water pipe structure uses a single-layer design. In cold weather, the water pipe structure is directly exposed, and the water inside the pipe is prone to freezing due to the low temperature. This affects the normal operation of the sprinkler. Furthermore, the water expands after freezing, creating expansion stress on the water pipe structure, which can easily cause damage and increase operating costs. Utility Model Content

[0004] The main purpose of this utility model is to provide a structure for an antifreeze and heat-insulating water pipe for a sprinkler truck, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water pipe structure for antifreeze and heat preservation of a sprinkler truck includes an exhaust pipe body and a spray pipe. The exhaust pipe body is provided with a discharge pipe, and the spray pipe is provided with a connecting pipe. The upper end of the connecting pipe is equipped with a connecting elbow, and the connecting elbow is provided with a heat exchange structure, which is wrapped around the discharge pipe.

[0006] Preferably, a mounting rod is provided in the middle part of the water spray pipe, and a fixing plate is fixedly provided at the upper end of the mounting rod. The two ends of the mounting rod are respectively welded to the water spray pipe and the fixing plate.

[0008] Preferably, the heat exchange assembly includes a spiral heat exchange tube, an inlet pipe, an outlet pipe, a drain connector, and a control valve. The inlet pipe and the outlet pipe are respectively located at both ends of the spiral heat exchange tube, and the spiral heat exchange tube is wound around the drain pipe. The drain connector is installed on the spiral heat exchange tube and is connected to the spiral heat exchange tube. The control valve is installed at the end of the drain connector.

[0009] Preferably, the thermal insulation and protection component includes a first thermal insulation cover, a second thermal insulation cover, through holes, a connecting plate, and a cavity.

The connecting plate is provided on the first and second thermal insulation covers, and the connecting plate is provided with mounting holes. A connecting bolt is provided in the mounting holes on the connecting plate, and a nut is provided at the end of the connecting bolt.

[0010] Compared with the prior art, this utility model has the following beneficial effects: The antifreeze and heat-insulating water pipe structure of this sprinkler truck, through the heat exchange structure, wraps the heat exchange components around the discharge pipe, which can absorb the waste heat generated by the exhaust gas during the operation of the sprinkler truck, realize the recovery and utilization of waste heat, and heat the water in low temperature weather, avoiding the water freezing structure caused by low temperature, thus ensuring the normal operation of sprinkler operation.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-4 As shown, a water sprinkler truck antifreeze and heat-insulating water pipe structure includes an exhaust pipe body 1 and a spray pipe 3. The exhaust pipe body 1 is provided with a discharge pipe 2, and the spray pipe 3 is provided with a connecting pipe 4. A connecting elbow 6 is installed at the upper end of the connecting pipe 4, and a heat exchange structure 5 is provided on the connecting elbow 6, which is wrapped around the discharge pipe 2. An installation rod 7 is provided in the middle part of the spray pipe 3, and a fixing plate 8 is fixedly installed at the upper end of the installation rod 7. The two ends of the installation rod 7 are welded to the spray pipe 3 and the fixing plate 8, respectively.

[0015] When the water truck is in use, during the driving process, the water in the water tank is pumped through the heat exchange structure 5, the connecting elbow 6, and the connecting pipe 4 to the spray pipe 3. Then, it is sprayed onto the ground through the spray holes of the spray pipe 3. During this process, the mounting rod 7 and the fixing plate 8 ensure the stable use of the spray pipe 3. At the same time, during the driving process of the water truck, the vehicle exhaust gas is discharged through the exhaust pipe 2 at the end of the exhaust pipe body 1. When the exhaust gas moves in the exhaust pipe 2, the residual heat acts on the heat exchange structure 5 to heat the water flowing in the heat exchange structure 5. This can ensure that the water temperature in the water pipe structure is relatively high in low temperature weather, avoid freezing, and effectively play a role in heat preservation and antifreeze.

[0016] According to the above implementation scheme, the heat exchange structure 5 includes a heat exchange component 501 and a thermal insulation component 502. The heat exchange component 501 is wrapped around the discharge pipe 2, and the thermal insulation component 502 is installed on the discharge pipe 2. The thermal insulation component 502 is wrapped around the middle section of the heat exchange component 501, and both ends of the heat exchange component 501 pass through the thermal insulation component 502.

[0017] When using heat exchange structure 5, heat exchange component 501 is wrapped around the outside of exhaust pipe 2. The residual heat in the exhaust gas exchanges heat with the water in heat exchange component 501 to increase the water temperature and ensure normal water spraying. Meanwhile, heat insulation and protection component 502 is located outside heat exchange component 501 and plays a role in heat insulation, which can prevent a large amount of heat loss and increase the heat exchange effect.

[0018] The heat exchange assembly 501 includes a spiral heat exchange tube 5011, an inlet pipe 5012, an outlet pipe 5013, a drain connector 5014, and a control valve 5015. The inlet pipe 5012 and the outlet pipe 5013 are respectively located at both ends of the spiral heat exchange tube 5011, and the spiral heat exchange tube 5011 is wound around the drain pipe 2. The drain connector 5014 is installed on the spiral heat exchange tube 5011 and is connected to the spiral heat exchange tube 5011. The control valve 5015 is installed at the end of the drain connector 5014.

[0019] During the water spraying process, water enters the spiral heat exchanger tube 5011 from the inlet pipe 5012. Under spiral flow conditions, the waste heat from the exhaust gas in the outlet pipe 2 heats the water in the spiral heat exchanger tube 5011. The heated water is then discharged from the outlet pipe 5013 and finally delivered to the spray pipe 3 for spraying. While the water is flowing through the spiral heat exchanger tube 5011, the control valve 5015 on the drain connector 5014 is closed, allowing the water to flow normally through the tube. After spraying is complete, the control valve 5015 is opened to drain the water from the spiral heat exchanger tube 5011, preventing freezing at night and ensuring normal subsequent use.

[0020] The thermal insulation and protection component 502 includes a first thermal insulation cover 5021, a second thermal insulation cover 5022, a through hole 5023, a connecting plate 5024, and a cavity 5025. The cavity 5025 is formed on the first thermal insulation cover 5021 and the second thermal insulation cover 5022, and the first thermal insulation cover 5021 and the second thermal insulation cover 5022 are sleeved on the discharge pipe 2. Two through holes 5023 are respectively provided on the first thermal insulation cover 5021 and the second thermal insulation cover 5022. The connecting plate 5024 is provided on the first thermal insulation cover 5021 and the second thermal insulation cover 5022, and the connecting plate 5024 is provided with mounting holes. A connecting bolt is provided in the mounting holes on the connecting plate 5024, and a nut is provided at the end of the connecting bolt.

[0021] When installing the thermal insulation and protection component 502, before the heat exchange component 501 is connected, the first thermal insulation cover 5021 and the second thermal insulation cover 5022 are fitted onto the discharge pipe 2 through the through holes 5023. The inlet pipe 5012 and the outlet pipe 5013 pass through the two through holes 5023 respectively. The connecting plates 5024 are brought together for alignment. At this time, the spiral heat exchange tube 5011 is located in the cavity 5025. The connecting plates 5024 are fixed using connecting bolts and nuts, thus completing the installation of the thermal insulation and protection component 502. During use, the first thermal insulation cover 5021 and the second thermal insulation cover 5022 play a role in heat preservation, which can prevent rapid heat loss, ensure heat exchange effect, and guarantee the effect of thermal insulation and antifreeze.

[0022] It should be noted that by using the heat exchange structure 5, the heat exchange component 501 is wound around the exhaust pipe 2, which can absorb the waste heat generated by the exhaust gas during the operation of the water truck, realizing the recovery and utilization of waste heat. It can heat the water in low-temperature weather, avoiding the water freezing structure caused by low temperatures, and ensuring the normal operation of watering. At the same time, no additional heating source is required. The spiral heat exchange tube 5011 is set in a spiral structure, which can increase the water travel and ensure the heat exchange effect. Each coil of the spiral heat exchange tube 5011 is equipped with a drain joint 5014 and a control valve 5015 at the lowest point. When the vehicle is parked at night, the control valve 5015 can be opened to drain the water in the spiral heat exchange tube 5011, preventing the water from freezing in the pipe. The heat insulation protection component 502 can cover the spiral heat exchange tube 5011, which can lock in as much heat as possible, reduce heat loss, and improve the heat exchange and insulation effect.
