Description

Technical Field

[0001] This invention relates to the field of water distributor technology, and more specifically, to a herringbone-type water distributor for heating and cooling. Background Technology

[0002] The heating and cooling stations of the prefabricated container smart energy heating system are an important application scenario for this herringbone-shaped water distributor; in this system, the heat or cold stored in the high-efficiency energy storage module needs to be evenly distributed to each heat exchange area through the water distributor.

[0003] When applied to building and boiler heating scenarios, i.e., heating for urban users, traditional methods often use two independent tanks to store hot and cold water separately to ensure that the hot and cold water supplies do not interfere with each other and to avoid mixing, which would make it difficult to control the temperature accurately. Therefore, most of them now use cold herringbone-type water distributors. The main body of the herringbone-type water distributor consists of an inlet pipe and multiple distribution pipes. The inlet pipe serves as the water inlet, and multiple distribution pipes are located at specific positions in its circumferential direction (i.e., the circumferential direction around the central axis). The end of these distribution pipes away from the inlet pipe is closed, and there are several outlets on the pipe wall, forming a radial layout similar to a fishbone.

[0004] However, when the herringbone-type water distributor is used, as the water flows from the head of the connecting pipe to multiple branch pipes, the water flow in the pipes generates resistance, and the magnitude of the resistance is related to the length of the pipe. The longer the line, the greater the resistance. This results in the branch pipes at the tail end, which are far from the water source, experiencing greater resistance, and the water flow speed is significantly slower than that of the branch pipes near the head. The different lengths of the lines lead to inconsistent water flow speeds, making it impossible to achieve uniform water distribution. This uneven water distribution phenomenon will seriously affect the uniformity and stability of heating or cooling. Therefore, we propose a herringbone-type water distributor for heating and cooling. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a herringbone-type water distributor for heating and cooling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fishbone-type water distributor for heating and cooling, comprising a connecting pipe, wherein several sets of equally spaced water outlets are provided on both sides of the connecting pipe, a branch pipe is installed inside each water outlet, a water flow detection component is installed at one end of the connecting pipe, the water flow in the connecting pipe is detected by the setting of the water flow detection component, a connecting plate is connected to one side of the connecting pipe, two symmetrical connecting brackets are installed on one side of the connecting plate, and rubber pads are installed on the outer side of the two connecting brackets, the outer wall of the rubber pads is in contact with the inner wall of the connecting pipe;

[0007] The water flow detection assembly includes a fixed pipe installed on one side of the connecting pipe, an outlet pipe installed at the bottom of the fixed pipe, a control valve installed at the outlet pipe, a sealing ring installed inside the fixed pipe, an adjusting rod installed inside the sealing ring, a rubber plug installed at one end of the adjusting rod, the rubber plug being located inside the fixed pipe, and the outer wall of the rubber plug fitting against the inner wall of the fixed pipe, a mounting bracket installed on the outer side of the fixed pipe, two symmetrical supports installed inside the mounting bracket, the two supports sharing a terminal and a metal rod, a resistance wire installed outside the terminal, a slider installed outside the metal rod, a connecting seat installed at the bottom of the slider, a slider installed at the bottom of the connecting seat, a sliding groove opened inside the mounting bracket, the slider slidingly connected inside the sliding groove, a spring installed on one side of the mounting bracket, one end of the spring connected to the connecting seat, one end of the adjusting rod connected to the connecting seat, and a pressure sensor installed on one side of one of the supports, corresponding to the position of the slider;

[0008] During the initial stage of water delivery, the rubber pad blocks the outlet hole, and the water accumulates in the connecting pipe. When the water flow detection component detects that the water delivery is complete, it automatically starts the motor to drive the rubber pad to rotate and expose the outlet hole, and the water flows into multiple branch pipes at the same time.

[0009] Preferably, a motor is installed on the rear side of the connecting pipe, and the output end of the motor is connected to the connecting plate.

[0010] Preferably, a rotating plate is installed on one side of the connecting plate, and a rotating groove is opened on one side of the inside of the connecting pipe, with the rotating plate rotatably connected inside the rotating groove.

[0011] The technical effects and advantages of this invention are as follows:

[0012] 1. In use, during the initial stage of water delivery, the rubber pad blocks the outlet hole, causing water to accumulate in the connecting pipe. When the water flow detection component detects that the water delivery is complete, it automatically starts the motor to rotate the rubber pad, exposing the outlet hole and allowing the water to flow simultaneously into multiple branch pipes. This effectively solves the problem of inconsistent water flow speed caused by the length of the line. Furthermore, through this unique structural design, the fishbone-shaped water distributor can achieve separate delivery of hot and cold water without interference, ensuring the supply of hot or cold water at the corresponding temperature. This avoids the problem of hot and cold water mixing that may occur in the traditional two-tank mode, effectively improving the temperature control accuracy and operating efficiency of the heating system.

[0013] 2. In use, the water flow detection component of this invention is ingeniously designed. When water flows through the connecting pipe, the water flow exerts pressure on the rubber stopper, pushing the rubber stopper to move. This, in turn, drives a series of components such as the adjusting rod and connecting seat to move, causing the slider to slide on the metal rod and change the circuit resistance value. Operators can observe the water source status of the connecting pipe in real time based on the change in resistance value. This precise water flow detection method provides a reliable basis for system control. When the connecting seat squeezes and contacts the pressure sensor, the system can accurately determine that the water source delivery is complete and automatically start the motor, realizing the automation and intelligence of system operation, improving the system's response speed and control accuracy, and further enhancing the overall performance of the heating and cooling station.

Detailed Implementation

[0022] 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.

[0023] As attached Figures 1-7 The diagram shows a fishbone-type water distributor for heating and cooling, comprising a connecting pipe 1, with several sets of equally spaced water outlet holes 2 on both sides of the connecting pipe 1, each water outlet hole 2 having a branch pipe 3 installed inside, a water flow detection component 4 installed at one end of the connecting pipe 1 to detect the water flow in the connecting pipe 1, a connecting plate 6 connected to one side of the inside of the connecting pipe 1, two symmetrical connecting brackets 7 installed on one side of the connecting plate 6, rubber pads 8 installed on the outer sides of the two connecting brackets 7, the outer wall of the rubber pads 8 fitting against the inner wall of the connecting pipe 1, a motor 5 installed at the rear of the connecting pipe 1, the output end of the motor 5 connected to the connecting plate 6, a rotating plate 9 installed on one side of the connecting plate 6, a rotating groove 10 opened on one side of the inside of the connecting pipe 1, and the rotating plate 9 rotatably connected inside the rotating groove 10;

[0024] In the initial state before water is supplied, the rubber pad 8 is tightly attached to the inner wall of the connecting pipe 1, completely blocking the water outlet holes 2 on both sides of the connecting pipe 1. At this time, water flows in from the head of the connecting pipe 1. Since the water outlet holes 2 are blocked, the water can only flow inside the connecting pipe 1. As the water flows inside the connecting pipe 1, it will exert pressure on the rubber plug 46 inside the fixed pipe 41. The outer wall of the rubber plug 46 is tightly attached to the inner wall of the fixed pipe 41. Under the pressure, the rubber plug 46 begins to move inside the fixed pipe 41. When the rubber pad 8 rotates and the water outlet holes 2 leak out, the water flows to multiple branch pipes 3 at the same time. One of the connecting brackets 7 and the rubber pad 8 have holes corresponding to the water flow detection component 4. The rotating plate 9 installed on one side of the connecting plate 6 rotates in the rotating groove 10 on one side of the connecting pipe 1, ensuring the stability of the rotation of the connecting plate 6.

[0025] The water flow detection assembly 4 includes a fixed pipe 41 installed on one side of the connecting pipe 1. A water outlet pipe 42 is installed at the bottom of the fixed pipe 41, and a control valve 43 is located at the position of the water outlet pipe 42. A sealing ring 44 is installed inside the fixed pipe 41, and an adjusting rod 45 is installed inside the sealing ring 44. A rubber plug 46 is installed at one end of the adjusting rod 45. The rubber plug 46 is located inside the fixed pipe 41, and its outer wall is in contact with the inner wall of the fixed pipe 41. A mounting bracket 47 is installed on the outer side of the fixed pipe 41. Two symmetrical supports 48 are installed inside the mounting bracket 47, and the two supports 48 share a common terminal block 49. A resistance wire 411 is provided on the outside of the metal rod 410 and the terminal 49. A slider 412 is provided on the outside of the metal rod 410. A connecting seat 413 is installed at the bottom of the slider 412. A slider 414 is installed at the bottom of the connecting seat 413. A groove 415 is opened inside the mounting bracket 47. The slider 414 is slidably connected inside the groove 415. A spring 416 is installed on one side of the inside of the mounting bracket 47. One end of the spring 416 is connected to the connecting seat 413. One end of the adjusting rod 45 is connected to the connecting seat 413. A pressure sensor 417 is installed on one side of one of the brackets 48 at the position corresponding to the slider 412.

[0026] During the initial stage of water delivery, the rubber pad 8 blocks the outlet hole 2, and water accumulates in the connecting pipe 1. When the water flow detection component 4 detects that the water delivery is complete, the motor 5 automatically starts, causing the rubber pad 8 to rotate and expose the outlet hole 2, allowing the water to flow simultaneously into multiple branch pipes 3.

[0027] When the water supply in the connecting pipe 1 is completed, until the connecting seat 413 squeezes and contacts the pressure sensor 417, the pressure sensor 417 will detect this pressure change and transmit the signal to the control system. The control system will determine that the water supply in the connecting pipe 1 is completed and then automatically start the motor 5. When emptying the water supply in the fixed pipe 41, the user only needs to open the control valve 43.

[0028] In a smart energy heating and cooling system built with prefabricated containers, the heat or cold stored in the high-efficiency energy storage module needs to be evenly distributed to each heat exchange area through a water distributor. Due to the complex layout of the heating and cooling station and the varying lengths of the branch pipes, traditional water distributors are unable to meet the requirements for uniform water distribution. However, this herringbone-shaped water distributor can adjust the water flow to ensure that each heat exchange area receives uniform heat or cold, thereby improving the efficiency and quality of heating or cooling and ensuring the stable operation of the heating and cooling station.

[0029] The working principle of this invention: When applied to building and boiler heating scenarios, i.e., for urban users, this fishbone-shaped water distributor innovatively achieves the function of separating hot and cold water and preventing them from interfering with each other within a single tank structure. The specific implementation method is as follows: In building and boiler heating systems, several sets of equidistant water outlets 2 opened on both sides of the water distributor connecting pipe 1, and the branch pipes 3 installed inside each water outlet 2 constitute the key diversion structure. In the initial state, the rubber pad 8 is tightly attached to the inner wall of the connecting pipe 1, completely blocking the water outlets 2 on both sides of the connecting pipe 1. At this time, hot water and cold water flow in the connecting pipe 1 according to their respective independent channels.

[0030] Through this unique structural design, the fishbone-shaped water distributor can flexibly control the flow of hot and cold water within a single tank structure according to actual needs, achieving separation of hot and cold water without interference, ensuring the supply of hot or cold water at the corresponding temperature, avoiding the problem of hot and cold water mixing that may occur in the traditional two-tank mode, effectively improving the temperature control accuracy and operating efficiency of the heating system, while reducing equipment costs and space occupation.

[0031] When hot water flows through the connecting pipe 1, the initial state of the rubber pad 8 blocks the water outlet holes 2 on both sides of the connecting pipe 1, and the water flows inside the connecting pipe 1. It will also exert pressure on the rubber plug 46 inside the fixed pipe 41. Under the pressure, the rubber plug 46 moves inside the fixed pipe 41, which drives the adjusting rod 45 to move. The adjusting rod 45 drives the connecting seat 413 connected at one end. The slider 414 at the bottom of the adjusting rod 45 slides in the slide groove 415 of the mounting bracket 47. At the same time, the spring 416 is compressed, and the slider 412 on the metal rod 410 slides with the connecting seat 413, changing the resistance value in the circuit. The operator can observe the water source status of the connecting pipe 1 by observing the change in resistance value. When the connecting seat 413 squeezes and contacts the pressure sensor 417, it means that the water source of the connecting pipe 1 has been delivered. At this time, the automatic motor 5 will start.

[0032] The output end of motor 5 drives the connecting plate 6 to rotate. When the connecting plate 6 rotates, the connecting bracket 7 and rubber pad 8 on one side rotate until the water outlet 2 leaks out. At this time, the water source flows to multiple branch pipes 3, thereby achieving uniform water distribution and solving the problem of inconsistent water flow speed caused by the length of the line.

[0033] Furthermore, to prevent mixing of hot and cold water, when cold water is needed after hot water has been supplied, the hot water supply stops. At this time, the motor 5 drives the connecting plate 6 to reset, and the rubber pad 8 blocks the outlet hole 2 again. At this time, hot water is discharged from the outlet hole 2 and several branch pipes 3. After the hot water is discharged, the rubber plug 46 is no longer squeezed. At this time, the spring 416 resets it, and then the control valve 43 is closed. Then, cold water is supplied. The principle of cold water flow detection component 4 is the same as that of hot water. After the water source is supplied through the connecting pipe 1, the outlet hole 2 leaks out, achieving uniform supply. This will not be described in detail here.

[0034] When the device does not require water supply, the rubber stopper 46 is no longer compressed. At this time, it is reset by the setting of spring 416. Then, the control valve 43 is opened to empty the water in the fixed pipe 41. At this time, the output end of the motor 5 also drives the connecting plate 6 to reset, which is convenient for subsequent use.
