Description

Technical Field

[0001] This utility model relates to the field of groundwater extraction technology, and in particular, to an automatic water extraction switching device. Furthermore, this utility model also relates to a shared water supply system including the aforementioned automatic water extraction switching device. Background Technology

[0002] In existing technologies, in areas without running water, such as remote rural areas, access to drinking water has become a major problem. Furthermore, due to geographical environment and climate, traditional wells cannot meet daily water needs, making large-scale machine-drilled wells the only option. However, machine-drilled wells are expensive, costing tens of thousands or even hundreds of thousands of yuan, which is usually unaffordable for a single household. Therefore, multiple households typically pool their resources to build a shared well.

[0003] Traditional shared water sources such as wells pump water and connect it to each user individually. Each user controls the opening and closing of their own pipeline via valves. When a user needs water, they must manually close all other valves while keeping their own valve open to start the pump. This process is complex, involves long distances, and is inconvenient, especially at night. Furthermore, if multiple households open their valves simultaneously, the water is distributed to each household, resulting in low flow rates and the risk of dry pumping, leading to a poor user experience and low water extraction efficiency. Utility Model Content

[0004] This utility model provides an automatic water intake switching device and a shared water supply system to solve the technical problems such as the inconvenience of water intake operation for multiple households sharing a well in the prior art.

[0005] According to one aspect of the present invention, an automatic water intake switching device is provided, comprising:

[0006] A housing, used as a structural support, has an inner cavity. A water inlet and multiple sets of water outlets are respectively provided on the housing. The water inlet is used to connect the inner cavity to a water source. The water outlets are located at the first end of the housing and are respectively connected to the inner cavity. The number of water outlets is greater than or equal to the number of water usage locations. The multiple sets of water outlets are evenly distributed circumferentially along the surface of the first end of the housing. Each water usage location is connected to one water outlet.

[0007] A switching actuator is disposed within the inner cavity and is used to be driven externally to move to a target position so that the water outlet at the corresponding position communicates with the inner cavity and closes the water outlets at the other positions.

[0008] A drive mechanism is disposed in the housing and located outside the inner cavity. The output end of the drive mechanism is connected to the conversion actuator for driving the conversion actuator to move.

[0009] The control unit is respectively set at each water position and electrically connected to the drive mechanism, and is used to control the drive mechanism to drive the conversion actuator to connect the water outlet of the corresponding water position to the inner cavity and then to the water inlet.

[0010] As a further improvement to the above technical solution, the conversion actuator includes a conversion valve plate disposed at the first end of the inner cavity. The conversion valve plate has a first connecting structure that matches the structure of the water outlet at a radial position corresponding to the water outlet. The conversion valve plate is used to rotate circumferentially under external drive so that the first connecting structure is located at a target angular position, thereby connecting the inner cavity and the water outlet at the target angular position.

[0011] As a further improvement to the above technical solution, the conversion actuator further includes a waterproof structure disposed between the conversion valve plate and the first end of the inner cavity. The waterproof structure is provided with a second connecting structure that matches the structure of the water outlet end. The circumferential distribution position of the second connecting structure matches the circumferential distribution position of the water outlet end.

[0012] As a further improvement to the above technical solution, a circumferential limiting structure is provided between the waterproof structure and the shell to limit the circumferential position of the second connecting structure of the waterproof structure installed on the shell relative to the water outlet end.

[0013] As a further improvement to the above technical solution, the drive mechanism is driven to connect with the switching valve plate through a transmission assembly. The transmission assembly includes a drive gear disposed at the output end of the drive mechanism, a driven gear meshing with the drive gear and coaxially arranged with the switching valve plate, and a transmission shaft with its two ends respectively connected to the driven gear and the switching valve plate. The drive gear and the driven gear are disposed in the housing and located outside the inner cavity. The transmission shaft passes through the housing and is fitted with a sealing ring.

[0014] As a further improvement to the above technical solution, a partition is provided inside the housing to divide the housing into an installation cavity and an inner cavity. The housing also includes a first cover at a first end and a second cover at a second end. The water outlet is located at the first cover. The driving gear and the driven gear are installed in the installation cavity. The partition has a through hole for the transmission shaft to pass through.

[0015] As a further improvement to the above technical solution, the driving mechanism is driven to the switching valve plate through a transmission assembly, and the transmission assembly and / or the switching valve plate are provided with a position detection unit for detecting the angular position of the first communication structure of the switching valve plate.

[0016] As a further improvement to the above technical solution, the housing is provided with a plurality of position marking units for cooperating with the position detection unit, and the axial distribution position of the position marking units matches the circumferential distribution position of the water outlet.

[0017] As a further improvement to the above technical solution, the automatic water intake switching device further includes a water pump disposed at the water inlet end. The control unit is electrically connected to the drive mechanism and the water pump respectively, and is used to turn on the water pump and control the drive mechanism to drive the switching actuator when the water pump is turned on. The control unit is also used to control the water pump to turn off. Alternatively, the water outlet end is connected to a water supply pipeline, and each water supply pipeline is provided with a water pump. Each control unit is electrically connected to the drive mechanism and the water pump at the corresponding position of the water outlet end, and is used to turn on the water pump at the corresponding position and control the drive mechanism to drive the switching actuator when the water pump is turned on. The control unit is also used to control the water pump at the corresponding position to turn off.

[0018] According to another aspect of the present invention, a shared water supply system is also provided, which includes the above-mentioned automatic water intake switching device.

[0019] This utility model has the following beneficial effects:

[0020] This underground water supply conversion device can be applied to shared water sources such as well water. It is structurally supported by a shell, with an inlet and an outlet connected to the inner cavity of the shell. The inlet connects to the shared water source. Each user can connect an outlet to their water intake or storage location. A control unit is located near each user's location (water intake or storage). When a user needs water, the control unit controls the drive mechanism to activate the conversion actuator, connecting the outlet at the corresponding user's location to the inner cavity, thus connecting the outlet to the inlet. Water then flows through the device to the corresponding user's location. This device allows users to access water directly from their location. Its streamlined structure and low manufacturing cost enable multiple households to access shared water sources, such as wells, eliminating the need for individual well digging and significantly reducing costs. The device, through a control unit, drive mechanism, and conversion actuator, connects to the corresponding water outlet and source when a user requests water. Users can easily access water from their designated location, greatly simplifying operation and making it more convenient. This also ensures sufficient water output, preventing issues like insufficient flow or difficulty in dispensing due to diversion.

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0029] Figure 1 This is a schematic diagram of the structure of a preferred embodiment of the present invention; Figure 2 This is a partial cross-sectional view of a preferred embodiment of the present invention; Figure 3 This is an exploded view of a preferred embodiment of the present invention.

[0030] like Figures 1 to 3 As shown, the automatic water intake switching device of this embodiment includes:

[0031] The housing 100 serves as a structural support and has an inner cavity 110. The housing 100 is provided with a water inlet 120 and multiple sets of water outlets 130. The water inlet 120 is used to connect the inner cavity 110 to a water source. The water outlets 130 are located at the first end of the housing 100 and are connected to the inner cavity 110. The number of water outlets 130 is greater than or equal to the number of water usage locations. The multiple sets of water outlets 130 are evenly distributed circumferentially along the surface of the first end of the housing 100, and each water usage location is connected to one water outlet 130.

[0032] The conversion actuator 200 is located inside the inner cavity 110 and is driven by the outside to move to the target position so that the water outlet 130 at the corresponding position is connected to the inner cavity 110 and the water outlet 130 at the other positions is closed.

[0033] A drive mechanism 300 is disposed in the housing 100 and located outside the inner cavity 110. The output end of the drive mechanism 300 is connected to the conversion actuator 200 for driving the conversion actuator 200 to operate.

[0034] The control unit is located at each water-using location and is electrically connected to the drive mechanism 300. It is used to control the drive mechanism 300 to drive the conversion actuator 200 to connect the outlet 130 of the corresponding water-using location to the inner cavity 110 and then to the inlet 120.

[0035] Preferably, each inlet end 120 has one inlet, and each outlet end 130 has one outlet. For easy connection to a pipeline, each outlet has an outwardly extending tubular structure for easy pipe insertion and removal. In other embodiments, the inlet end 120 may have multiple inlets, and each outlet end 130 may also have multiple outlets. It should be understood that the control unit can be implemented using existing electrical switches, circuit breakers, or other control units with the same function, and there are no restrictions on its implementation. The control unit can be integrated with a water valve or water pump at the user's location. For example, when water is drawn through the water pump at the user's location, the actuator 200 is activated to connect or open the corresponding outlet end 130. When the water tap is switched at a user's location, the switching actuator 200 activates to connect the corresponding water outlet 130. Each control unit corresponds to a water outlet position. This device should include a control system, which can be implemented based on existing control boards, etc. It is electrically connected to each control unit and drive mechanism, and can perform control based on the set control logic. For example, after the control unit issues a command, it determines whether to control the drive mechanism to activate based on the current position. If the connection position matches, it does not activate and directly starts the water pump. If the connection position does not match, it drives the switching actuator to activate the water pump to start water tapping after alignment. Alternatively, it can determine the priority based on the activation sequence of the control units, and switch to the next user's water tapping position after the current user has finished tapping water.

[0036] Understandably, the local underground water supply conversion device can be applied to shared water sources such as well water. It is structurally supported by a housing 100, and has an inlet end 120 and an outlet end 130 connected to the inner cavity 110 of the housing 100. The inlet end 120 is connected to the shared water source. Each user can connect an outlet end 130 to their water intake or storage location. A control unit is installed near each user's location, such as the water intake or storage location. When a user needs water, the control unit controls the drive mechanism 300 to drive the conversion actuator 200, connecting the outlet end 130 at the corresponding user's location to the inner cavity 110, thus allowing water to flow out. End 130 is connected to inlet end 120, and water flows through this device to the corresponding user location to obtain water. The device has a simple overall structure and low manufacturing cost. By using this device, multiple households can access shared water sources such as well water, allowing multiple users to share a single water source without the need for each household to dig a separate well, thus significantly reducing economic costs. This device, through the control unit, drive mechanism, and conversion actuator, can selectively connect the corresponding outlet end and water source when a user has a water demand. Users only need to perform simple operations at the water intake location in their home to obtain water, greatly reducing the difficulty of operation and making it more convenient to use. At the same time, it ensures the water output and avoids problems such as insufficient water flow and difficulty in water output caused by diversion.

[0037] In some embodiments, the switching actuator 200 includes a switching valve plate 210 disposed at the first end of the inner cavity 110. The switching valve plate 210 has a first connecting structure 211 that matches the structure of the water outlet 130 at a radial position corresponding to the water outlet 130. The switching valve plate 210 is used to be driven to rotate circumferentially by an external force so that the first connecting structure 211 is located at a target angular position, thereby connecting the inner cavity 110 and the water outlet 130 at the target angular position. It should be understood that the cross-section of the first connecting structure 211 and the water outlet is a hole structure. Each water outlet 130 is located at a different angular position. By driving the switching valve plate 210 to rotate to the corresponding angular position, the water outlet 130 at the corresponding angular position can be connected to the inner cavity 110 through the first connecting structure 211. The water source only flows through this passage to ensure the water flow rate.

[0038] In some embodiments, the switching actuator 200 further includes a waterproof structure 220 disposed between the switching valve plate 210 and the first end of the inner cavity 110. The waterproof structure 220 is provided with a second communication structure 221 that matches the structure of the water outlet 130. The circumferential distribution position of the second communication structure 221 matches the circumferential distribution position of the water outlet 130. The second communication structure 221 matches the structure of the water outlet 130, that is, it is perforated and its distribution position and number match the water outlet 130. The waterproof structure 220 can be a sealing gasket, which achieves waterproofing by maintaining an axial tight fit with the end face of the housing 100 and the switching plate. On the other hand, under the action of water pressure in the inner cavity 110, the switching valve plate 210 is pressured to maintain abutting fit with the waterproof structure 220 and presses it against the inner wall of the inner cavity 110, ensuring a sealing effect.

[0039] Furthermore, a circumferential limiting structure is provided between the waterproof structure 220 and the housing 100 to limit the circumferential position of the second connecting structure 221 of the waterproof structure 220 installed on the housing 100 relative to the water outlet 130. By providing the circumferential limiting structure, the operation rotation of the switching valve plate 210 is prevented from causing the waterproof structure 220 to shift and the second connecting structure 221 to shift in the angular position. Specifically, the circumferential limiting structure can be an annular boss that protrudes axially from the inner end of the water outlet 130. The annular boss is embedded in the second connecting structure 221, which not only ensures the circumferential position of the waterproof structure 220 is fixed, but also ensures the positional accuracy of each water outlet 130 and the corresponding second connecting structure 221, thus ensuring the communication performance and sealing performance.

[0040] In some embodiments, the drive mechanism 300 is drivenly connected to the switching valve plate 210 via a transmission assembly 400. The transmission assembly 400 includes a drive gear 410 disposed at the output end of the drive mechanism 300, a driven gear 420 meshing with the drive gear 410 and coaxially arranged with the switching valve plate 210, and a transmission shaft 430 with its two ends respectively connected to the driven gear 420 and the switching valve plate 210. The drive gear 410 and the driven gear 420 are disposed in the housing 100 and located outside the inner cavity 110. The transmission shaft 430 passes through the housing 100 and is fitted with a sealing ring 431. It is understood that the drive mechanism 300 is located outside the inner cavity 110 to avoid contact with the liquid. The drive mechanism 300 and the switching valve plate 210 are driven by the transmission assembly 400. The transmission assembly 400 and the switching valve plate 210 are coaxially arranged with a drive shaft 430 and a driven gear 420. The drive mechanism 300 drives the driven gear 420 meshing with it to rotate via the driving gear 410, thereby driving the drive shaft 430 to rotate synchronously with the switching valve plate 210. Only the drive shaft 430 passes through the inner cavity 110. Therefore, a sealing ring 431 is fitted at the gap between the drive shaft 430 and the housing 100 for sealing.

[0041] In some embodiments, a partition 140 is provided inside the housing 100 to divide the housing 100 into an installation cavity and an inner cavity 110. The housing 100 also includes a first cover 700 disposed at a first end of the housing 100 and a second cover 800 disposed at a second end of the housing 100. A water outlet 130 is disposed at the first cover 700. A drive gear 410 and a driven gear 420 are installed in the installation cavity. The partition 140 has a through hole 141 for a drive shaft 430 to pass through. The housing 100 is positioned at the through hole 141. An extended guide sleeve 142 is provided to allow the drive shaft 430 to pass through, preventing misalignment. At the same time, the gap between the drive shaft 430 and the guide sleeve 142 makes it easier to install the sealing ring 431, and multiple rings can be installed for easy installation and to ensure sealing. The partition 140 is also provided with a mounting plate 150 for mounting the drive mechanism 300. The output end of the drive mechanism 300 passes through the mounting plate 150 and connects to the drive gear 410 in the mounting cavity, further separating the drive mechanism 300 from the inner cavity 110 to prevent water ingress and damage.

[0042] In this preferred embodiment, the housing 100 is provided with a plurality of position marking units 600 for cooperating with the position detection unit 500. The axial distribution of the position marking units 600 matches the circumferential distribution of the water outlet 130. The position marking units 600 are electrically connected to the control module of the drive mechanism 300. The position marking units 600 and the position detection unit 500 can achieve position detection through magnetic induction or other means. In this embodiment, the position marking units 600 are disposed on the mounting plate 150, and the position detection unit 500 is disposed on the driven gear 420 and rotates with it. The position marking units 600 and the water outlet 130 are corresponding one-to-one. The position of element 500 is matched with the position of the first connecting structure 211. The position of the first connecting structure 211 and the water outlet 130 is determined based on the position of the position detection unit 500 and the position marking unit 600 to ensure connectivity. The position detection unit and the position marking unit are implemented based on existing position sensors, etc. After the control unit issues a command, the position is determined by the position detection unit, and then it is determined whether to control the drive mechanism to act. If the connection position matches, no action is taken and the water pump is directly turned on. If the connection position does not match, the drive conversion actuator is activated to align and then the water pump is turned on to draw water. On the other hand, the position detection unit can also perform position correction to ensure the position accuracy after long-term use.

[0043] The two ends of the drive shaft 430 are connected to the driven gear 420 and the conversion valve plate 210 respectively by a flat key, so that the circumferential position of the two is matched after installation. A circumferential limiting structure is set between the mounting plate 150 and the housing 100 to ensure that the circumferential position of the mounting plate 150 is fixed, thereby ensuring that the position marking unit 600 corresponds one-to-one with the water outlet 130.

[0044] In other embodiments, the drive mechanism 300 may be driven to the switching valve plate 210 via the transmission assembly 400. The transmission assembly 400 and / or the switching valve plate 210 may be provided with a position detection unit 500 electrically connected to the control module of the drive mechanism 300. This unit is used to detect the angular position of the first connecting structure 211 of the switching valve plate 210. By setting the position detection unit 500 to monitor the angular position of the switching valve plate 210, the position accuracy can be verified based on the angular position of the switching valve plate 210. Position detection is performed during operation, and the drive mechanism 300 is further corrected to ensure the position accuracy of the first connecting structure 211 and each water outlet 130. The position detection unit 500 may be set on the transmission assembly 400 and / or the switching valve plate 210, and preferably set outside the inner cavity 110 of the transmission assembly 400 to avoid contact with liquid and ensure service life.

[0045] In some embodiments, the automatic water intake switching device further includes a water pump disposed at the water inlet 120. The control unit is electrically connected to the drive mechanism 300 and the water pump respectively, and is used to turn on the water pump and control the drive mechanism 300 to drive the switching actuator 200 to operate when the water pump is turned on. The control unit is also used to control the water pump to turn off. Alternatively, the water outlet 130 is connected to a water supply pipeline, and each water supply pipeline is provided with a water pump. Each control unit is electrically connected to the drive mechanism 300 and the water pump at the corresponding position of the water outlet 130 respectively, and is used to turn on the water pump at the corresponding position and control the drive mechanism 300 to drive the switching actuator 200 to operate when the water pump is turned on. The control unit is also used to control the water pump at the corresponding position to turn off.
