Description

Technical Field

[0001] This utility model relates to the field of water intake pile technology, and more specifically, to plateau antifreeze water intake piles. Background Technology

[0002] Water intake piles are key facilities in water conservancy projects, municipal water supply, and water systems in high-altitude and cold regions. They are mainly used to safely and efficiently extract surface water or groundwater. In high-altitude and cold regions, temperature variations are extreme. At night, the temperature in these areas can drop sharply below 0 degrees Celsius, causing shallow water to freeze. Since water intake piles are installed on the surface, the water inside their pipes is easily frozen after the temperature drops, as the water remains stagnant. This makes it impossible for personnel to extract water during the day due to blockages caused by frozen water.

[0003] A Chinese utility model patent, titled "A Constant-Temperature Water Intake Pile for High-Altitude Areas" and with publication number CN217949213U, includes a support column and a pile head. One end of the support column has several connecting plates, each with a first connecting hole. The pile head has a connecting groove with a through hole at its bottom, through which a water pipe passes. The water pipe has a connecting plate and a valve, and is bolted to the connecting groove. An electric heating tape is installed between the water pipe and the support column. This utility model provides constant internal temperature control for the water intake pile and allows for easy disassembly and maintenance.

[0004] Although this invention can maintain a constant temperature inside the water intake pile using an electric heating element, preventing the water temperature inside the pipe from dropping too low and thus making it less prone to freezing, it requires a continuous power supply to heat the water intake pile to maintain a constant temperature. However, in high-altitude and cold regions, power supply is difficult and electricity is scarce. For individual households using residential water intake piles, the power consumption is too high and difficult to bear. Moreover, the installation location is limited to the area where electricity is transmitted, making its application area relatively small for the vast high-altitude regions. Utility Model Content

[0014] Preferably, the sleeve assembly is covered with a frost protection layer.

[0016] Preferably, the sleeve assembly includes a sleeve.

[0017] Preferably, the sleeve is vertically fixed inside the outer shell, the inside of the sleeve is hollow, and cover plates are fixed at both ends of the sleeve length. The cover plates have through holes that connect to the inside of the sleeve, forming a pipe structure.

[0018] Preferably, the hole in the bottom cover plate of the casing is connected to an underground well or water pipe.

[0019] Preferably, the valve assembly includes a water supply pipe.

[0020] Preferably, the water supply pipe is vertically slidably inserted through the hole in the top cover plate of the sleeve, and a plug is fixedly installed at the lower end of the water supply pipe inside the sleeve.

[0021] Preferably, the plug is inserted into the water supply chamber, and the water supply chamber has a water flow port running through it from top to bottom. The diameter of the plug is larger than the diameter of the water flow port on the water supply chamber, and smaller than the diameter of the chamber inside the water supply chamber.

[0022] Preferably, the diameter of the water supply pipe is the same as the diameter of the water inlet.

[0023] Preferably, a pressing component is connected to the upper part of the valve assembly, and a reset component is provided between the pressing component and the sleeve assembly.

[0024] Preferably, the reset assembly includes a sleeve and a spring.

[0025] Preferably, the sleeve is fixedly fitted onto the top of the water pipe, and a flange is fixedly installed on the sleeve. The upper end of the flange is fixedly connected to the flange, and the lower end of the spring is fixedly connected to the cover plate on the top of the sleeve assembly.

[0026] Preferably, the pressing assembly includes a connecting rod and a pressing rod, and the water outlet includes a three-way valve pipe and a water tap.

[0028] Preferably, the top of the three-way valve pipe is fixedly connected to and sealed with the connecting rod, and both ends of the connecting rod extend laterally through the outer casing, with one end of the connecting rod being fixedly connected to the pressure rod.

[0029] Preferably, the outer casing is further provided with a locking component, which includes a limiting plate and a pin hole.

[0030] Preferably, the limiting plate is fixed outside the outer shell, and the end of the connecting rod without the pressure rod is slidably connected in the limiting groove inside the limiting plate, with the sliding direction being vertical.

[0031] Preferably, the lower end of the limiting plate has multiple pin holes, and the direction of the pin hole channel is perpendicular to the axial direction of the connecting rod.

[0032] Preferably, when water is being drawn, the connecting rod is located at the lower end of the limiting plate and below the pin hole.

[0033] The technical solution of this application has at least the following advantages and beneficial effects:

[0034] In this utility model, by setting a valve assembly inside the sleeve assembly, a displaceable piston structure is formed inside the pipe. The operator can press the pressing assembly to make the piston structure displace inside the pipe, which can restrict the flow of underground wells or water pipes inside the sleeve assembly, so that pressurized water can only pass through the sleeve assembly and flow into the water tap when the piston structure is open, reducing the residual static water flow inside the sleeve assembly, thereby reducing the occurrence of water freezing.

[0035] In this invention, in order to reduce the volume of stagnant water flow inside the casing assembly, a water supply chamber is provided inside the casing assembly. The water supply chamber controls the flow of water by moving the plug, so that the water flowing into the water supply chamber through the inlet can no longer flow. This restricts the water flow to the smaller water supply chamber space and connects it with the continuously flowing water flow in the underground well or water pipe, so that the water flow in the water supply chamber will not be stagnant, thereby reducing the occurrence of water freezing in the pipe when no more water is drawn.

[0036] In this invention, to prevent the residual water in the pipe after water intake from affecting subsequent water intake operations, a water inlet is provided at the lower end of the sleeve assembly and at the lower end of the antifreeze cover. When water supply stops, the residual water in the pipe can flow into the sleeve through the water inlet, and then the water will pass through the water inlets on the sleeve and the antifreeze cover in sequence to drain the water in the pipe. This reduces the possibility of the accumulated water clogging the pipe after freezing. The draining process is achieved only through the piston structure and the water inlet, and there is no need to maintain a constant temperature of the water in the pipe through electric heating. It is suitable for installation environments without power supply.

[0037] In this invention, in order to further reduce the impact and damage of external temperature on the inside of the device (long-term cold conditions can easily lead to cracking of the cylinder), an antifreeze cover is also wrapped around the outside of the sleeve of the sleeve assembly. The antifreeze cover is a heat insulation layer, which can reduce the conduction of external low temperature to the sleeve and improve the service life of the sleeve assembly.

[0046] Example

[0047] Please refer to Figures 1-5 This utility model provides a plateau antifreeze water intake pile, including a sleeve assembly 2. The sleeve assembly 2 is a pipe structure. The upper part of the pipe structure is connected to a water tap 7, and the lower part is inserted and installed on the ground or building, and connected to an underground well or water pipe.

[0048] The sleeve assembly 2 is also covered by an outer shell 1 for protection. The outer shell 1 includes a cover 101 and a base 102. The cover 101 is fixedly sleeved on the outside of the sleeve assembly 2. The base 102 is fixedly fixed at the bottom of the cover 101. The base 102 is fixedly connected to the lower part of the sleeve assembly 2. The base 102 is fixed to the ground or building and has a through hole to provide a water pipe, which is the water inlet.

[0049] In existing technology, pressurized water from underground wells or pipes flows directly into the casing assembly 2 and is then blocked by the valve of the outlet tap 7. When the tap is manually opened, the pressurized water flows out directly. However, when this structure is applied to high-altitude areas, the long-term cold climate causes the pre-pumped water in the casing assembly 2 to freeze easily due to the low temperature when it is stored statically within the pipe structure, affecting the normal outflow of water.

[0050] Therefore, in this embodiment, a valve assembly 3 is also provided inside the casing assembly 2. The top of the valve assembly 3 is connected to the pressing assembly 4, so that the operator can press the pressing assembly 4, which allows the valve assembly 3 to be displaced. The valve assembly 3 forms a displaceable piston structure inside the pipe of the casing assembly 2. By displacing the piston structure inside the pipe, the flow of underground wells or water pipes inside the casing assembly 2 can be restricted, so that pressurized water can only flow through the casing assembly 2 and into the water tap 7 when the piston structure is open, thereby reducing the residual static water flow inside the casing assembly 2 and reducing the occurrence of water freezing.

[0051] Please refer to the following: Figures 2-5 The sleeve assembly 2 includes a sleeve 201, a cover plate 202, a water supply chamber 203, and a water inlet 204.

[0052] The valve assembly 3 includes a water supply pipe 301, a plug 302, and a water inlet 303.

[0053] Specifically, the sleeve 201 is vertically fixed inside the cover 101. The sleeve 201 is hollow inside, and cover plates 202 are fixed at both ends of the sleeve. The cover plates 202 have through holes that connect to the inside of the sleeve, forming a pipe structure. The holes in the cover plate 202 at the bottom of the sleeve connect to the water inlet on the base 102, allowing pressurized water to flow into the sleeve.

[0054] A water supply pipe 301 is vertically slidably inserted through the hole in the top cover plate 202 of the sleeve, and a plug 302 is fixedly installed at the lower end of the water supply pipe 301 that enters the sleeve. The lower part of the hollow interior of the casing is fixed to the water supply chamber 203, which has a water flow outlet running vertically through it. The plug 302 is inserted into the water supply chamber 203, and the diameter of the plug 302 is larger than the diameter of the water flow outlet on the water supply chamber 203. The diameter of the water supply pipe 301 is the same as the diameter of the water flow outlet, so that the plug 302 cannot be removed from the chamber. Moreover, when the plug 302 reaches the top of the chamber, it can block the water flow outlet at the top of the water supply chamber 203, so that the water flowing into the casing through the inlet and then into the water supply chamber 203 inside the casing cannot continue to flow upward. This restricts the water flow to the smaller space of the water supply chamber 203 and connects it with the continuously flowing water in the underground well or water pipe (so the water flow in the water supply chamber 203 will not be stagnant). This reduces the possibility of the water in the pipe freezing when the tap 7 is closed and no more water is used.

[0055] In addition, to reduce the amount of water remaining in the casing while maintaining normal water supply, a water inlet 303 is connected to the end of the water supply pipe 301 near the plug 302, and the top of the water supply pipe 301 is connected to the water outlet 7. The working principle of water supply by the combined action of the casing assembly 2 and the valve assembly 3 is as follows:

[0056] When the water tap 7 is closed and the pressure component 4 is not pressed down, the plug 302 is located at the top of the water supply chamber 203, blocking the water supply chamber 203. At this time, the water inlet 303 on the water supply pipe 301 is located in the water supply chamber 203. The water supply chamber 203 and the water inlet 303 are not connected, and the pressurized water does not flow into the water supply pipe 301. There is no water flow in the water supply pipe 301 and the sleeve 201.

[0057] When the faucet 7 is turned on, the pressure component 4 is pressed down, causing the water supply pipe 301 and the plug 302 to move down. The plug 302 moves away from the bottom of the water supply chamber 203, and the water inlet 303 on the water supply pipe 301 begins to move down into the internal space of the water supply chamber 203 (it is worth noting that the diameter of the plug 302 is smaller than the diameter of the water supply chamber 203, so it will not block the internal space of the chamber). This allows the pressurized water in the water supply chamber 203 to flow into the water supply pipe 301, and then flow through the water supply pipe 301 to the faucet 7 for water to be dispensed.

[0058] When the water supply is stopped and the water outlet faucet 7 is closed, the pressure component 4 moves upward and resets, causing the water supply pipe 301 and the plug 302 to move upward. The water inlet 303 moves out of the water supply chamber 203, and the plug 302 blocks the top of the water supply chamber 203. The pressurized water no longer flows into the water supply pipe 301, but only remains in the water supply chamber 203.

[0059] Furthermore, in order to further reduce the impact and damage of external temperature on the internal parts of the device (long-term cold conditions can easily lead to cracking of the cylinder), an antifreeze cover 6 is also wrapped around the outside of the sleeve 201 of the sleeve assembly 2. The antifreeze cover 6 is a heat insulation layer, which can reduce the conduction of external low temperature to the sleeve 201 and improve the service life of the sleeve assembly 2.

[0060] Furthermore, during the water delivery process described above, the pressure-down component 4 can be manually operated, but when the water delivery ends, a stable reset structure is required to reset the water delivery pipe 301 and the plug 302. Therefore, a reset component 5 is also provided at the upper end of the water delivery pipe 301, which includes a sleeve and a spring 502.

[0061] Please refer to Figure 4 The sleeve is fixedly fitted onto the top of the water supply pipe 301. A flange is provided on the sleeve, and the upper end of the spring 502 is fixedly connected to the flange of the sleeve. The lower end of the spring 502 is fixedly connected to the cover plate 202 on the top of the sleeve assembly 2. The top end of the water supply pipe 301 is connected to the pressing assembly 4. When the pressing assembly 4 is pressed, the water supply pipe 301 moves downward and the spring 502 elastically contracts. When the pressing assembly 4 is released, the water supply pipe 301 is only subjected to the elastic force of the spring 502, thus elastically moving upward and returning to its original position.

[0062] Furthermore, although the pressurized water flow is confined within the water supply chamber 203 and no longer remains within the sleeve 201, when the water outlet 7 is closed and the water supply pipe 301 moves upward, some water remains in the water supply pipe 301. This water will also freeze and block the water supply pipe 301, affecting subsequent water supply operations.

[0063] Therefore, please refer to Figure 5 A water inlet 303 is also provided at the lower end of the sleeve 201 of the sleeve assembly 2, and at the lower end of the antifreeze cover 6. When water supply stops and the water pipe 301 moves upward, the water inlet 303 is located in the space inside the sleeve 201. This allows the residual water in the water pipe 301 to flow from the water inlet 303 into the sleeve 201 after being lowered by gravity. Then, the water flows through the water inlets 303 on the sleeve 201 and the antifreeze cover 6 in sequence, causing most of the water in the water pipe 301 and the sleeve assembly 2 to flow out. This reduces the possibility of excessive water accumulation in the sleeve assembly 2 and the water pipe 301, which could block the water pipe 301 after freezing. Furthermore, the temperature of the remaining water after freezing outside the antifreeze cover 6 is unlikely to affect the sleeve assembly 2.

[0064] Example 2

[0065] Because the device needs to be installed on the ground or building surface in the field and water is dispensed by manual pressure, a locking device is also provided on the outer shell 1 to facilitate long-term water collection by personnel during actual use. This device can temporarily lock the pressing component 4 so that it can maintain water supply even when it is not under pressure, without the need for continuous manual pressure.

[0066] Please refer to Figures 2-4 The pressing component 4 includes a connecting rod 401, a slider 402, a sliding cavity plate 403, and a pressure rod 404.

[0067] The water tap 7 includes a three-way valve pipe 701, a water tap 702, and a slider 703.

[0068] The locking assembly 8 includes a limit plate 801 and a pin hole 802.

[0069] Specifically, the lower pipe of the three-way valve pipe 701 is fixedly connected to the water supply pipe 301, and the horizontal pipe of the three-way valve pipe 701 is connected to the faucet 702, so that the water flow in the water supply pipe 301 is guided to the faucet 702. The faucet 702 is installed outside the outer casing 1 for external water dispensing.

[0070] The top of the three-way valve pipe 701 is fixedly connected to the connecting rod 401 (the end of the connecting rod 401 seals the upper part of the three-way valve pipe 701). Both ends of the connecting rod 401 extend horizontally through the outer casing 1. One end of the connecting rod 401 is fixedly connected to the pressure rod 404 for easy manual operation. The other end of the connecting rod 401 is slidably positioned within the limiting groove of the limiting plate 801, sliding vertically along the groove. The limiting plate 801 is fixed to the outside of the outer casing 1. Multiple pin holes 802 are drilled through the lower end of the limiting plate 801. When water is drawn, the operator presses down the pressure rod 404, which in turn drives the connecting rod 404... When the connecting rod 401 and the water pipe 301 move down, the connecting rod 401 moves from the upper part of the limiting plate 801 to the lower part of the limiting plate 801, and then the pressurized water flows into the water pipe 301 to start water delivery. At this time, the pin is inserted into the pin hole 802 located above the connecting rod 401, so that when the person releases the pressure rod 404, the reset component 5 drives the water pipe 301 to move up and reset. The connecting rod 401 will be restricted by the pin above it and cannot be reset, thus maintaining the water delivery state until the person removes the pin in the pin hole 802 and the water pipe 301 is reset, at which point the water delivery will stop.

[0071] Since both the connecting rod 401 and the faucet 702 extend through the outer shell 1 and are fixedly connected to the water supply pipe 301, in order to prevent the connecting rod 401 and the faucet 702 from interfering with the outer shell 1 when they move vertically along with the water supply pipe 301, vertical grooves corresponding to the connecting rod 401 and the faucet 702 (its water pipe part) are also provided on the outer shell 1. Each groove is matched with the vertical displacement path of the connecting rod 401 and the faucet 702 (its water pipe part).

[0072] In addition, because the pressure rod 404 and the connecting rod 401 are relatively light, it is quite difficult to press them manually. Moreover, the thinner rod ends and pipe ends are prone to bending and breaking under stress. Therefore, slider 1 402 is also fixedly installed on the pressure rod 404 and the connecting rod 401, and slider 2 703 is also fixedly installed on the water pipe part of the faucet 702. The two sliders are slidably installed on the outer shell 1. The two sliders can protect the rod ends and pipes while the connecting rod 401 and the faucet 702 are vertically displaced, making them less prone to bending and reducing the occurrence of sliding obstruction after bending.

[0073] Meanwhile, slider 402 slides in the chute plate 403, which is fixed to the outer shell 1. The chute plate 403 uses the spacing of the slots in its middle to limit the vertical displacement of the pressure rod 404 on slider 402, so that personnel can quickly confirm the pressing position required for water delivery, that is, the position where the pressure rod 404 moves down and touches the lower part of the chute plate 403.

[0074] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
