Description

Technical Field

[0001] This utility model relates to a pipeline antifreeze control device, and in particular to a water truck water filling and pipeline antifreeze control device, belonging to the field of water supply pipeline antifreeze technology. Background Technology

[0002] For example, application number 202020968077.9 is the closest prior art. The prior art discloses the method of concentrating the remaining fresh water in the ship's water filling pipe into the water collection tank, which solves the problem of water pipe freezing due to incomplete drainage when adding water to the ship during winter navigation. The prior art achieves the function of preventing freezing by draining the residual water in the pipe. However, some of the equipment in the prior art is placed in the foundation pit, which leads to water accumulation during rain, snow accumulation during snowfall, hail accumulation during hail, and fallen leaves accumulation. With the changing seasons, the dirt in the foundation pit comes into direct contact with the parts and equipment in the foundation pit, causing corrosion of the parts and equipment. The water tank and the corresponding pipe cannot achieve the function of preventing freezing.

[0003] Therefore, based on the above-mentioned shortcomings, a water truck water filling and pipeline antifreeze control device is needed to improve the above-mentioned shortcomings. Utility Model Content

[0004] The main purpose of this utility model is to provide a water truck water filling and pipeline antifreeze control device.

[0005] The objective of this utility model can be achieved by adopting the following technical solution: A water truck water filling and pipeline antifreeze control device includes a foundation pit for placing parts, a water storage tank installed on one side of the bottom of the foundation pit, a water injection pipe connected to one side of the water storage tank, a water storage tank pipe inserted into the other side of the water storage tank, a constant pressure water supply pump installed at the outer end of the water storage tank pipe, a water supply pipe distributed at one output end of the constant pressure water supply pump, a water replenishment pipe installed at the outer end of the water supply pipe, and the water supply pipe and the water replenishment pipe being connected by a connecting solenoid valve assembly. The water storage tank, constant pressure water supply pump, water supply pipeline and connecting solenoid valve assembly are covered by a cover, and reinforcing ribs are installed in the cavity of the cover. The cover is buried in the ground.

[0006] Preferably, the thickness of the ground is 0.5M-3M.

[0007] Preferably, the connecting solenoid valve assembly includes a flow divider 3-way one, a constant pressure solenoid valve, and a flow divider 3-way two; A diversion tee is installed at the outer end of the water supply pipe. A constant pressure solenoid valve is installed at one end of the diversion tee, and a bend is installed at the other end of the diversion tee. A diversion tee is assembled at the outer end of the bend.

[0008] Preferably, one end of the diversion tee is connected to a water supply pipe, and the other end of the diversion tee is equipped with a drain pipe. A drain solenoid valve is installed at the outer end of the drain pipe, and the output end of the drain solenoid valve is connected to the sewage drainage tank.

[0009] Preferably, the constant pressure water supply pump, the constant pressure solenoid valve, and the drain solenoid valve are equipped with wireless transceivers, and the outer end of the water supply pipe is equipped with a water receiving solenoid valve.

[0010] Preferably, a limiting support rod is sleeved on the outside of the water storage tank pipe and the water supply pipe. Support plates are installed at the upper and lower ends of the limiting support rod, and anti-slip parts are installed on the contact surface between the inner ring of the limiting support rod and the water storage tank pipe and the water supply pipe. The anti-slip parts at both ends of the limiting support rod are connected to the ground and the inner side of the cover for support.

[0011] Preferably, an upper water level monitoring device and a lower water level monitoring device are installed on one side of the water storage tank, respectively.

[0012] The beneficial technical effects of this utility model are as follows: This utility model provides a water truck water filling and pipeline antifreeze control device. 1) After the equipment is in place, the cover is firmly placed on top of the water storage tank, constant pressure water supply pump, sewage drainage tank and water supply pipe. This cover plays an important role. It completely isolates the ground from the equipment and parts below. In this way, rainwater, moisture and various corrosive substances on the ground cannot directly contact the equipment and parts, effectively avoiding the problems of shortened equipment life and easy corrosion caused by direct contact. It greatly improves the durability of the equipment and reduces the later maintenance costs and replacement frequency. After the enclosure was installed, the construction workers began backfilling the ground. They carefully filled the top of the enclosure and the exposed gaps outside the foundation pit with soil to ensure the compaction of the backfill soil, so that the ground would be flat again and the stability of the entire system would be further enhanced. This application allows for flexible adjustment of the excavation depth of the foundation pit and the thickness of the backfill on the ground, depending on different environmental conditions and temperatures. For example, in cold northern regions, the depth of the foundation pit can be appropriately increased to place the equipment below the frost line, while the thickness of the backfill can be increased. By utilizing the thermal insulation properties of the soil and in conjunction with the protection of the enclosure, an effective thermal insulation layer can be formed, perfectly solving the problem that water storage tanks, sewage drainage tanks and their pipelines are prone to freezing in winter, ensuring the normal operation of the entire water supply system in severe cold weather. In relatively warmer regions, the depth of the foundation pit and the thickness of the ground can be appropriately reduced, thereby reducing construction costs while ensuring system functionality. To facilitate subsequent water replenishment operations, the water supply pipe is specially led out to a suitable location in the design, which does not affect the overall protective structure and allows operators to easily carry out water replenishment operations.

[0013] 2) The constant pressure solenoid valve at the outer end of the diversion tee on the water supply pipeline reduces the pressure in the water supply pipeline and the water supply pipe. When the drain solenoid valve is not activated, the water is discharged through the water supply pipeline, the diversion tee, the water supply pipe and the water receiving solenoid valve. When the water inlet solenoid valve stops discharging water, the drain solenoid valve is activated to discharge the residual water in the water supply pipe, the diversion tee, and the water supply pipe into the sewage drainage tank. This discharge of residual water in the water supply pipe, the diversion tee, and the water supply pipe achieves antifreeze heating. The constant pressure solenoid valve and the drain solenoid valve are equipped with wireless transceivers, which can be operated remotely.

[0014] 3) The limiting struts are respectively sleeved on the outside of the water storage tank pipe and the water supply pipe, and the struts on both sides abut against the inner bottom of the cover and the ground, thus forming a stable support structure. The above structure further enhances the load-bearing capacity of the enclosure, while also effectively limiting the water storage tank pipeline and the water supply pipeline, achieving a dual optimization of structural stability and pipeline positioning accuracy.

[0017] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0018] Example 1

[0019] like Figure 1 As shown, this embodiment provides a water truck water filling and pipeline antifreeze control device, including a pit 7 for placing parts, a water storage tank 1 installed on one side of the bottom of the pit 7, a water injection pipe 101 connected to one side of the water storage tank 1, a water storage tank pipe 201 inserted into the other side of the water storage tank 1, a constant pressure water supply pump 2 installed at the outer end of the water storage tank pipe 201, a water supply pipe 204 distributed at one output end of the constant pressure water supply pump 2, a water replenishment pipe 6 installed at the outer end of the water supply pipe 204, and the water supply pipe 204 and the water replenishment pipe 6 are connected by a connecting solenoid valve assembly; The water storage tank 1, constant pressure water supply pump 2, water supply pipeline 204 and connecting solenoid valve assembly are covered by a cover 4. Reinforcing ribs 401 are installed in the cavity of the cover 4 and the cover 4 is buried in the ground 5. The thickness of the ground 5 is 0.5M-3M; like Figure 1 As shown, firstly, the construction workers excavate the foundation pit 7 according to the design requirements. The depth of the foundation pit will be determined according to the local climate conditions, especially the thickness of the frozen soil layer in winter. Then, the water storage tank 1, constant pressure water supply pump 2, sewage drainage tank 3 and water supply pipe 6 are precisely hoisted to the bottom of the foundation pit to ensure that the positional relationship between each piece of equipment meets the design specifications, laying a good foundation for subsequent pipeline connection and other work. like Figure 1 As shown, after the equipment is in place, the cover 4 is steadily placed on top of the water storage tank 1, the constant pressure water supply pump 2, the sewage drainage tank 3 and the water supply pipe 6. This cover plays an important role, completely isolating the ground 5 from the equipment and parts below. In this way, rainwater, moisture and various corrosive substances on the ground cannot directly contact the equipment and parts, effectively avoiding the problems of shortened equipment life and easy corrosion caused by direct contact, greatly improving the durability of the equipment, and reducing the later maintenance costs and replacement frequency. After the cover 4 was installed, the construction workers began backfilling the ground 5. They carefully filled the top of the cover 4 and the exposed gaps outside the foundation pit 7 with soil to ensure the compaction of the backfill soil, so that the ground would be flat again and the stability of the entire system would be further enhanced. This application allows for flexible adjustment of the excavation depth of the foundation pit 7 and the backfill thickness of the ground 5 according to different environmental conditions and temperatures. For example, in cold northern regions, the depth of the foundation pit can be appropriately increased to place the equipment below the frost line, while the thickness of the ground backfill can be increased. By utilizing the thermal insulation properties of the soil and in conjunction with the protection of the enclosure, an effective thermal insulation layer can be formed, which perfectly solves the problem that the water storage tank 1, the sewage drainage tank 3 and their pipelines are prone to freezing in winter, ensuring the normal operation of the entire water supply system in severe cold weather. In relatively warm climate regions, the depth of the foundation pit and the thickness of the ground can be appropriately reduced to reduce construction costs while ensuring system functionality. To facilitate subsequent water addition operations, the water supply pipe 6 is specially designed to be led out to a suitable location, which does not affect the overall protective structure and allows operators to easily carry out water addition operations.

[0021] The solution in Example 1 will be further described below with reference to its specific working method. like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, an upper water level monitoring device 102 and a lower water level monitoring device 103 are respectively installed on the upper and lower sides of one side of the water storage tank 1. The connecting solenoid valve assembly includes a flow divider 3-way one 206, a constant pressure solenoid valve 207, and a flow divider 3-way two 209; A diversion tee 1 206 is installed at the outer end of the water supply pipe 204. A constant pressure solenoid valve 207 is installed at one end of the diversion tee 1 206, and a bend 205 is installed at the other end of the diversion tee 1 206. A diversion tee 2 209 is assembled at the outer end of the bend 205.

[0022] One end of the diversion tee 209 is connected to a water supply pipe 6, and a drain pipe 301 is installed at one end of the diversion tee 209. A drain solenoid valve 302 is installed at the outer end of the drain pipe 301, and the output end of the drain solenoid valve 302 is connected to the sewage drainage tank 3. like Figure 1 and Figure 2 As shown, the constant pressure solenoid valve 207 at the outer end of the diversion tee 1 206 on the water supply pipe 204 reduces the pressure in the water supply pipe 204 and the water supply pipe 6. When the drain solenoid valve 302 is not activated, the water is discharged through the water supply pipe 204, the diversion tee 2 209, the water supply pipe 6 and the water receiving solenoid valve 601. When the water inlet solenoid valve 601 stops discharging water, the drain solenoid valve 302 is activated to discharge the remaining water in the water supply pipe 204, the diversion tee 209, and the water supply pipe 6 into the sewage drainage tank 3. This discharge of the remaining water in the water supply pipe 204, the diversion tee 209, and the water supply pipe 6 achieves antifreeze heating. The constant pressure solenoid valve 207 and the drain solenoid valve 302 are equipped with wireless transceivers 208, which can be operated remotely.

[0023] Example 3

[0024] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a limiting support rod 8 is further provided on the outer side of the water storage tank pipe 201 and the water supply pipe 204. Support plates 802 are respectively installed at the upper and lower ends of the limiting support rod 8. Anti-slip parts 801 are installed on the contact surface between the inner ring of the limiting support rod 8 and the water storage tank pipe 201 and the water supply pipe 204. The anti-slip parts 801 at both ends of the limiting support rod 8 are connected to the ground 5 and the inner side of the cover 4 for support. like Figure 1 and Figure 2 As shown, the limiting support rods 8 are respectively sleeved on the outside of the water storage tank pipe 201 and the water supply pipe 204, and the support plates 802 on both sides abut against the inner bottom of the cover 4 and the ground 5, thereby forming a stable support structure. The above structure further enhances the load-bearing capacity of the cover 4, while also effectively limiting the water storage tank pipe 201 and the water supply pipe 204, achieving a dual optimization of structural stability and pipe positioning accuracy.
