Description

Technical Field

[0001] This invention relates to the field of building heating technology, specifically to a linear water distributor for heating and cooling. Background Technology

[0002] A water distributor is a device used to evenly distribute fluids (such as hot water, steam, etc.) to a specific area or equipment. Its core function is to achieve a balanced distribution of flow rate and pressure during the flow process through reasonable structural design, so as to avoid local flow rates that are too large or too small.

[0003] In the water distribution process of heating and cooling systems, traditional water distributors often face two major problems: First, the impact of water flow during water intake causes significant shaking. This turbulent flow not only exacerbates uneven water distribution but also results in significant differences in water supply to different areas of the storage tank, thus affecting the uniform storage and release of heat. Second, the fixed height of the water distribution pipe makes it impossible to flexibly adjust according to changes in the liquid level in the tank or the need for stratification of hot and cold water. This easily stirs up the water in the tank, causing the mixing of hot and cold fluids, disrupting the temperature stratification structure, and significantly reducing heat storage performance, making it difficult to meet the operational requirements of efficient heating and cooling systems. Therefore, a linear water distributor for heating and cooling is proposed to solve these problems. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a linear water distributor for heating and cooling, which solves the problems mentioned in the background section.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a linear water distributor for heating and cooling, comprising a main pipe, a connecting pipe, and an adjustment structure, wherein the connecting pipe is movably connected to the main pipe through a retractable adjustment structure;

[0008] The bottom of the main pipe is provided with water spray structures at both ends, and a buffer structure is provided at the junction of the water spray structure and the main pipe. One end of the buffer structure is connected to a dispersion cover, and a cleaning structure is provided in the middle of the two.

[0009] The buffer structure includes a flow guide shroud and a spiral flow guide plate on the inner wall, the spiral flow guide plate to guide the water flow to form a spiral flow;

[0010] The cleaning structure includes a shaft with a tail cone with a tail fin fixed at one end and a dispersion hood rotatably connected at the other end. An impeller and a cleaning rod are fixed on the shaft, and the bristles of the cleaning rod are in contact with the inner wall of the dispersion hood.

[0011] The spiral flow first impacts the tail fin, driving the impeller to rotate initially. Its rotational kinetic energy then continues to accelerate the impeller, causing the buffer structure and the cleaning structure to work together through the same spiral flow. After being dispersed by the dispersion hood, the spiral flow forms a gentle water flow.

[0012] Preferably, the dispersion hood includes a first truncated cone and a connected second truncated cone, wherein the first truncated cone has an inclined groove and the second truncated cone has a straight groove.

[0013] Preferably, a connecting cover is fixed at one end of the flow guide cover of the buffer structure, and the connecting cover is connected to the first truncated cone of the dispersion cover.

[0014] Preferably, the water spray structure includes a connecting pipe and a water pipe fixed at one end, and the water pipe has a plurality of water distribution holes, the diameter of which gradually increases along the direction away from the connecting pipe.

[0015] Preferably, the dispersion cover is provided with a fixing ring, and the end of the shaft away from the tail cone is rotatably connected to the fixing ring.

[0016] Preferably, the tail fin is installed at an angle, with its tilt direction consistent with the spiral direction of the spiral guide plate, and the force-bearing surface of the tail fin forms an acute angle with the flow direction of the spiral flow.

[0017] Preferably, the adjustment structure includes two first fixed discs, a bellows and a guide rod, one end of the main pipe passes through one of the first fixed discs and is fixedly connected to the second fixed disc, and the second fixed disc is slidably connected to the guide rod.

[0018] Preferably, a mounting base is fixed on the side wall of another of the first fixed disks, and a motor is fixed on the mounting base;

[0019] A slide block is fixed on the side wall of the second fixed plate. The slide block is threadedly engaged with the lead screw, so that when the motor drives the lead screw to rotate, the second fixed plate rises and falls along the guide rod.

[0020] Beneficial effects

[0021] The present invention has the following beneficial effects:

[0022] (1) This linear water distributor for heating and cooling achieves a progressive effect of "buffering and stabilizing flow to energy reuse and then uniform water distribution" through the combined design of a guide plate, a double-truncated cone dispersion cover and a variable diameter water distribution hole: the spiral guide plate guides the water flow to form a spiral flow, which weakens the impact of the incoming water by rotating the water flow and avoids the local turbulence caused by the direct water flow in traditional water distributors; on the other hand, the kinetic energy of the spiral flow drives the cleaning structure to automatically clean the inner wall of the dispersion cover, preventing impurities from clogging the water distribution hole and ensuring smooth water flow. The inclined groove and straight groove of the double-truncated cone disperse the spiral flow for a second time. Combined with the design of "gradually larger diameter at the far end" of the water distribution hole, it balances the pressure loss along the flow path and solves the problem of "excessive flow at the near end and insufficient flow at the far end" in traditional water distributors, thereby improving the uniformity of water supply and avoiding the decrease in heat storage or cooling efficiency caused by local water supply imbalance.

[0023] (2) This linear water distributor for heating and cooling achieves flexible adaptation of water distribution height through its adjustable structure: the motor-driven screw drives the bellows to extend and retract, and the guide rod ensures the verticality of the adjustment process. The height of the water distributor can be precisely adjusted according to changes in the liquid level in the water tank or the interface between hot and cold layers, avoiding the problem of "water distribution point deviating from the target area" caused by liquid level fluctuations in traditional fixed-height water distributors. The height adjustment function ensures that the water distributor is always aligned with the target water temperature layer, reducing the disturbance of hot and cold fluids in the water tank during the water distribution process, avoiding the "mixing of hot and cold fluids" phenomenon caused by the fixed height of traditional water distributors, reducing the heat storage / cooling loss rate, and improving system energy efficiency.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a technical solution: such as Figures 1-6 As shown, a linear water distributor for heating and cooling includes a main pipe 1, a connecting pipe 3, and an adjusting structure 2. The connecting pipe 3 is movably connected to the main pipe 1 through the retractable adjusting structure 2.

[0034] The bottom of the main pipe 1 is provided with water spray structure 4 at both ends. A buffer structure 5 is provided at the junction of the water spray structure 4 and the main pipe 1. One end of the buffer structure 5 is connected to the dispersion cover 6, and a cleaning structure 7 is provided in the middle of the two.

[0035] The buffer structure 5 includes a flow guide shroud 501 and a spiral flow guide plate 503 on the inner wall. The spiral flow guide plate 503 guides the water flow to form a spiral flow.

[0036] The cleaning structure 7 includes a shaft 701, one end of which is fixed to a tail cone 702 with a tail fin 703, and the other end is rotatably connected to the dispersion hood 6. An impeller 704 and a cleaning rod 705 are fixed on the shaft 701, and the bristles of the cleaning rod 705 are attached to the inner wall of the dispersion hood 6.

[0037] The spiral flow first impacts the tail fin 703, driving the impeller 704 to rotate initially. Its rotational kinetic energy then continues to accelerate the impeller 704, causing the buffer structure 5 and the cleaning structure 7 to be linked through the same spiral flow. After the spiral flow is dispersed by the dispersion shroud 6, it forms a gentle water flow.

[0038] Specifically, the dispersion cover 6 includes a first truncated cone 601 and a connected second truncated cone 603. The first truncated cone 601 is provided with an inclined groove 602, and the second truncated cone 603 is provided with a straight groove 605.

[0039] Specifically, a connecting cover 504 is fixed at one end of the flow guide cover 501 of the buffer structure 5. The connecting cover 504 is connected to the first truncated cone 601 of the dispersion cover 6. The cone angle of the first truncated cone 601 is 60°-90°, which matches the diffusion angle of the spiral flow. The cone angle of the second truncated cone 603 is 120°-150°, which realizes the secondary expansion and deceleration of the water flow. The two work together to release the kinetic energy of the spiral flow step by step.

[0040] Specifically, the water spray structure 4 includes a connecting pipe 401 and a water pipe 402 fixed at one end. The water pipe 402 has multiple water distribution holes 403, and the diameter of the water distribution holes 403 gradually increases in the direction away from the connecting pipe 401.

[0041] Specifically, the dispersion cover 6 is provided with a fixing ring 604, and the end of the shaft 701 away from the tail cone 702 is rotatably connected to the fixing ring 604.

[0042] Specifically, the tail fin 703 is installed at an angle, with its tilt direction consistent with the spiral direction of the spiral guide plate 503. The force-bearing surface of the tail fin 703 forms an acute angle with the flow direction of the spiral flow, and the tail cone 702 is a conical structure with its cone surface facing the direction of the water flow, which is adapted to the incident direction of the spiral flow. This conical design can disperse the water flow impact through the streamlined surface, avoiding the 'water flow turbulence' caused by the traditional straight structure. While receiving the spiral flow energy to drive the tail fin 703, it reduces the water flow resistance by more than 30%, ensuring that the spiral flow energy of the buffer structure 5 is efficiently converted into the rotational kinetic energy of the clean structure 7, rather than causing energy loss due to excessive resistance.

[0043] Specifically, the adjustment structure 2 includes two first fixed plates 202, a bellows 201 and a guide rod 208. One end of the main pipe 1 passes through one of the first fixed plates 202 and is fixedly connected to the second fixed plate 206, and the second fixed plate 206 is slidably connected to the guide rod 208.

[0044] Specifically, a mounting base 203 is fixed on the side wall of another first fixed plate 202, and a motor 204 is fixed on the mounting base 203;

[0045] A slide 207 is fixed on the side wall of the second fixed plate 206. The slide 207 is threadedly engaged with the lead screw 205, so that when the motor 204 drives the lead screw 205 to rotate, the second fixed plate 206 rises and falls along the guide rod 208.

[0046] Install liquid level sensors, such as ultrasonic level gauges, and temperature sensors, such as platinum resistance sensors, at different heights inside the water storage tank to monitor the liquid level and water temperature distribution at different depths in real time and identify the cold and hot stratification interface.

[0047] The sensor data is transmitted to the PLC controller. The controller automatically triggers the motor 204 to move according to preset thresholds, such as when the liquid level is lower or higher than the target value, or when the water distribution point deviates from the hot and cold stratification interface by ±5cm. The motor 204 is then driven to lift the main pipe 1 through the screw 205 until the water distribution height matches the current liquid level or the hot and cold stratification requirement.

[0048] During the adjustment process, the bellows 201 expands and contracts synchronously to compensate for the water circuit and ensure water flow is sealed, thus avoiding disturbance to the water flow during adjustment.

[0049] The water distributor is installed inside the water storage tank. The connecting pipe 401 of the spray structure is fixed to the bottom of the main pipe 1 through the flange structure. The mounting seat 203 of the adjustment structure is fixed to the inner wall of the water storage tank to complete the overall position fixation.

[0050] The external water supply pipe is sealed and connected to the connecting pipe 3, so that the water flow can enter the corrugated pipe 201 of the regulating structure through the connecting pipe 3, and finally flow into the main pipe 1 to complete the water circuit connection; the water flow of the water supply pipe enters the main pipe 1 through the connecting pipe 3 and the corrugated pipe 201, and then the main pipe 1 is divided to the connecting pipes 401 at both ends.

[0051] Before the water flows into the connecting pipe 401, it first enters the guide shroud 501 of the buffer structure, and is guided by the spiral guide plate 503 to form a spiral vortex, which weakens the initial impact through the rotation of the water flow.

[0052] When the spiral vortex flows through the mounting bracket 505, the reduced pipe diameter creates a spiral pressurization effect, which then enters the connecting cover 504, providing energy for the subsequent driving of the cleaning structure and the dispersion of water flow. The impact force of the spiral vortex first acts on the tail fin 703 of the cleaning structure, pushing the shaft 701 to drive the impeller 704 to rotate initially. The pressurized spiral flow continues to act on the impeller 704, further increasing its speed and forming a stable driving force.

[0053] The impeller 704 drives the cleaning rod 705 on the shaft 701 to rotate synchronously. The bristles on the cleaning rod 705 adhere to the inner walls of the first truncated cone 601 and the second truncated cone 603 of the dispersion cover, cleaning the impurities in the inclined groove 602 and the straight groove 605 in real time to avoid clogging.

[0054] The water on the outer side flows through the inclined groove 602 of the first truncated cone 601, which is inclined at an angle to match the spiral flow direction and disperses the water, reducing the flow velocity before entering the connecting pipe 401. The water in the middle flows through the straight groove 605 of the second truncated cone 603 and disperses it again, forming a gentle water flow that flows into the connecting pipe 401. After entering the water pipe 402, the water flows out through the water distribution holes 403, which have a gradually increasing diameter in the direction away from the connecting pipe 401, thus balancing the pressure loss along the way and achieving uniform water distribution.

[0055] Loosen the flange connection between the main pipe 1 and the connecting pipe 401; hold the handle 502 on the inner wall of the guide shroud 501, rotate the guide shroud 501 to separate it from the inner thread of the connecting pipe 401, remove the buffer structure 5, rotate the first truncated cone 601 to separate it from the connecting shroud 504, and then you can clean or replace the dispersion shroud 6, cleaning structure 7 and other components separately.

[0056] When the motor 204 starts, its output drives the lead screw 205 to rotate. When the lead screw 205 rotates, the slide 207, which is threaded with the lead screw, is fixed to the side wall of the second fixed plate 206, converting the rotational motion into linear motion. This causes the second fixed plate 206 to slide along the guide rod 208. Since one end of the main pipe 1 passes through one of the first fixed plates 202 and is fixedly connected to the second fixed plate 206, the lifting and lowering of the second fixed plate 206 will directly drive the main pipe 1 to lift and lower synchronously, thereby adjusting the water distribution height. During the lifting and lowering of the main pipe 1, the two ends of the corrugated pipe 201, which is sleeved on the outside, are connected to the two first fixed plates and passively extend and retract with the displacement of the main pipe. This ensures the water circuit is sealed and compensates for the length change between the main pipe and the connecting pipe 3, preventing water leakage or structural jamming during the adjustment process.
