Description

Technical Field

[0001] This invention relates to the field of connecting pipe technology, specifically to a connecting pipe for a liquid-cooled driven water pump and its operating method. Background Technology

[0002] In the liquid cooling system of equipment such as robots, electric vehicles and electric motorcycles, the water pump connecting pipe is the core component for realizing coolant delivery, sealing and vibration reduction. It needs to adapt to the extreme working conditions of cold start at a low temperature of minus 40 degrees Celsius and high temperature circulation heat dissipation at a high temperature of 120 degrees Celsius. However, some problems still occur in the actual use of existing pump connecting pipes. For example, patent application number CN202322473947.1 discloses a water pump pipe connection device, including an intermediate connecting pipe, a sleeve, a clamping assembly, and a sealing ring; the sleeve is coaxially fitted onto the outside of the intermediate connecting pipe, with a gap between the sleeve and the intermediate connecting pipe; a pair of sealing rings are respectively fixedly installed at the outer edges of the two ends of the intermediate connecting pipe, so that when two water pump pipes are respectively fitted onto the two ends of the intermediate connecting pipe, the intermediate connecting sleeve is sealed to the water pump pipe through the sealing rings, which has the characteristic of preventing water leakage due to breakage. Most existing pump connecting pipes have single functions and are prone to aging and wear under alternating high and low temperature conditions, leading to coolant leakage and posing a safety hazard of flammable medium leakage.

[0003] To address the aforementioned problems, a connecting pipe for a liquid-cooled driven water pump and its operating method are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a connecting pipe for a liquid-cooled driven water pump and its operating method. By using this device, the problem of existing pump connecting pipes having limited functions and being prone to aging and wear under alternating high and low temperature conditions, leading to coolant leakage and potential safety hazards such as leakage of flammable media is solved.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connecting pipe for a liquid-cooled driven water pump, comprising a connecting pipe body and a sleeve pipe disposed on the outside of the connecting pipe body, wherein both the connecting pipe body and the sleeve pipe are provided in two sets; the inner side of the connecting pipe body is provided with a threaded groove, wherein multiple sets of threaded grooves are provided; one end of the connecting pipe body is provided with an installation box; a retaining groove is provided on the top of the connecting pipe body near one end; one end of one set of the connecting pipe body is fixedly connected to a connecting block; the inside of the sleeve pipe is fixedly connected to a receiving block, wherein multiple sets of receiving blocks are provided; and the inner side of the receiving block is fixedly connected to a support frame.

[0006] Preferably, the mounting box is provided in two sets, with a knob rotatably connected to the top of the mounting box and a transmission screw fixedly connected to the bottom of the knob.

[0007] The above-described design allows for the synchronous rotation of the transmission screw through manual rotation of the knob, transforming the manual operation of tightening into the circumferential motion of the screw. This provides a power source for the subsequent locking of the connecting pipe body. Furthermore, the fixed connection structure between the knob and the transmission screw is simple, has high transmission efficiency, and has no complex transmission components.

[0008] Preferably, the transmission screw is threadedly connected to a sliding block, the sliding block is slidably connected inside the mounting box, and the bottom end of the sliding block is provided with two sets.

[0009] The above-mentioned structural design utilizes the threaded transmission between the screw and the slider to convert the circumferential motion of the transmission screw into the linear reciprocating motion of the slider, thereby achieving automatic locking and unlocking of the connecting pipe body without the need for additional locking components. The design of the two sets of bottom ends can simultaneously engage with the slots of the two sets of connecting pipe bodies to achieve synchronous locking of the two connecting pipe bodies, improving assembly efficiency.

[0010] Preferably, the sliding block slides into the slot, and a spring rod is rotatably connected inside the mounting box, with one end of the spring rod fixedly connected to a rotating block.

[0011] The above-mentioned structural design allows for precise locking and positioning of the connecting pipe body and the mounting box through the sliding engagement of the sliding block and the slot, preventing axial or circumferential displacement of the connecting pipe body during use and improving the sealing and stability of the connection.

[0012] Preferably, the rotating block is slidably engaged with the knob, and one end of the other set of connecting pipe bodies is provided with a connecting groove, which is slidably engaged with the connecting block.

[0013] With the above-mentioned structural design, the sliding cooperation between the rotating block and the knob enables flexible unlocking of the anti-loosening structure. Pulling the rotating block will release the knob from its lock, making operation simple.

[0014] Preferably, one end of the other set of connecting pipe bodies is also provided with a sealing groove, the sealing groove is slidably engaged with the set of connecting pipe bodies, and the internal support frame is fixedly connected with a card interface.

[0015] With the above-mentioned structural design, the sliding fit between the sealing groove and the connecting pipe body forms a two-stage sealing structure. Combined with the sealing element, it can significantly improve the sealing performance at the joint of the two sets of connecting pipe bodies, further preventing coolant leakage.

[0016] Preferably, the sleeve is internally fixedly connected to a pressure-resistant ring, and multiple sets of pressure-resistant rings are provided. A fixed ball is fixedly connected to the outer side of the pressure-resistant ring.

[0017] With the above-mentioned structural design, multiple sets of pressure-resistant rings are evenly distributed along the axial direction of the bushing, which can effectively improve the overall pressure resistance of the bushing, resist the force brought by external extrusion and collision, and prevent the deformation of the bushing from causing damage to the internal connecting pipe body and blockage of the fluid channel.

[0018] Preferably, multiple sets of fixed spheres are provided, and a connecting rod is fixedly connected between two sets of fixed spheres. A friction block is fixedly connected to the outside of the connecting rod.

[0019] With the above-mentioned structural design, the connecting rod connects multiple sets of fixed spheres and anti-compression rings into a whole, so that the sleeve pipe forms a mesh-like anti-compression support structure, which greatly improves the structural stability and anti-deformation ability of the sleeve pipe and avoids the detachment of a single component under stress.

[0020] Preferably, a packaging body is fixedly connected to the outer side of the connecting rod, a fixing ring is fixedly connected to the outer side of the sleeve, a friction pad is fixedly connected to the inside of the fixing ring, and a protrusion is fixedly connected to the outer side of the fixing ring.

[0021] With the above-mentioned structural design, the packaging body wraps and protects the connection parts of the connecting rod, friction block and anti-pressure ring, preventing the connection parts from aging and falling off due to media corrosion and high and low temperature alternation, thus extending the service life of the sleeve.

[0022] A method for operating a connecting pipe of a liquid-cooled driven water pump includes the following steps: Step 1: When using the device, insert the two sets of connecting tube bodies into the inside of the mounting box, and at the same time complete the connection of the two sets of connecting tube bodies by turning the knob on the mounting box. Step 2: Fit the two sets of sleeves onto the outside of the connecting pipe body, and then fix the sleeves to the outside of the connecting pipe body with the fixing ring to prevent the sleeves from falling off the connecting pipe body. Step 3: Operate at the specified temperature. The threaded grooves inside the connecting pipe body prevent leakage when the fluid passes through them. The fluid can also be guided in multiple segments for better circulation, better heat dissipation, and more controllable cooling water circulation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application improves both sealing reliability and mass production consistency. By using a multi-segment cylindrical connection structure at both ends of the connector pipe to form a multi-level seal with the sealing element, and combining it with a closed static sealing component to replace the traditional dynamic seal, the problem of coolant "running, leaking, dripping and leaking" under high and low temperature conditions of minus forty degrees to one hundred and twenty degrees is completely solved. At the same time, the standardized connection and locking design reduces the assembly precision requirements, realizes the mass production of qualified products, and eliminates the safety hazards of leakage of flammable, explosive and other media.

[0024] 2. This application significantly optimizes fluid transmission and heat dissipation efficiency by using multi-segment spiral guide grooves on the inner wall of the connector to guide the coolant to form a stable laminar flow, reducing turbulence and resistance during fluid transmission, making fluid conduction smoother and circulation heat dissipation more efficient, achieving precise and controllable cooling of cold water circulation, and meeting the stringent temperature control requirements for cold start of motors and high-temperature heat dissipation of battery packs in robots, electric vehicles and electric motorcycles.

[0025] 3. The system vibration reduction and energy consumption control of this application are excellent. The fixed and locked connection method of the support block effectively absorbs the vibration and impact generated by the operation of the water pump and the working conditions of the equipment, reducing the mutual influence of vibration between the motor and the pump body. At the same time, the closed static seal design of the pump shaft does not require an independent lubrication and cooling water system, which greatly reduces the overall energy consumption of the equipment. In addition, the rotor can slip on the ceramic shaft when overloaded, which provides effective overload protection for the motor and pump body and extends the service life of the whole machine.

[0026] 4. This application enhances the ease of installation and maintenance, as well as the adaptability to various operating conditions. The integrated support and locking structure allows for quick disassembly and assembly of the connecting pipe and other components, facilitating pump inspection, replacement, and cleaning and maintenance of the pipeline system. The overall structure of the connecting pipe is adapted to the requirements of magnetic drive, and simple maintenance operations such as filtration and flushing can ensure the service life of the bearing friction pair. Furthermore, it can achieve over-temperature alarm / shutdown via a temperature sensor, adapting to liquid-cooled drive water pump systems of different power levels, making it suitable for a wide range of scenarios.

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.

[0030] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0031] Combination Figures 1-3 A connecting pipe for a liquid-cooled driven water pump includes a connecting pipe body 1 and a sleeve 2 disposed on the outside of the connecting pipe body 1. Both the connecting pipe body 1 and the sleeve 2 are provided in two sets. The inner side of the connecting pipe body 1 is provided with a threaded groove 11, and multiple sets of threaded grooves 11 are provided. One end of the connecting pipe body 1 is provided with a mounting box 12. A slot 13 is provided on the top of the connecting pipe body 1 near one end. One end of a connecting pipe body 1 is fixedly connected to a connecting block 131. The inside of the sleeve 2 is fixedly connected to a receiving block 21, and multiple sets of receiving blocks 21 are provided. The inner side of the receiving block 21 is fixedly connected to a support frame 211.

[0032] The present invention will be further described below with reference to embodiments.

[0033] Example 1: To address the problem that existing pump connection pipes are mostly single-function and prone to aging and wear under alternating high and low temperature conditions, leading to coolant leakage and potentially flammable media leakage, this embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, the mounting box 12 has two sets of knobs. A knob 121 is rotatably connected to the top of the mounting box 12. A transmission screw 122 is fixedly connected to the bottom of the knob 121. A sliding block 123 is threadedly connected to the transmission screw 122. The sliding block 123 is slidably connected inside the mounting box 12. Two sets of sliding blocks 123 are provided at the bottom end, and the sliding blocks 123 slide in engagement with the slots 13. A spring rod 124 is rotatably connected inside the mounting box 12. One end of the spring rod 124 is fixedly connected to a rotating block 125. The rotating block 125... The knob 121 is slidably engaged. One end of the other set of connecting pipe bodies 1 has a connecting groove 132, which slidably engages with the connecting block 131. Another end of the other set of connecting pipe bodies 1 also has a sealing groove 133, which slidably engages with one set of connecting pipe bodies 1. During use, the two sets of connecting pipe bodies 1 can be installed on the left and right sides of the mounting box 12. After inserting the connecting pipe bodies 1 into the mounting box 12, the connecting groove 132 at one end of one set of connecting pipe bodies 1 connects with the other set of connecting pipe bodies 1. The connecting block 131 at one end of the pipe body 1 engages, thus completing the installation of the two sets of connecting pipe bodies 1. Then, the knobs 121 located on the upper and lower sides of the mounting box 12 can be rotated. The knobs 121 drive the transmission screw 122 to rotate, thereby causing the sliding block 123 to move. The sliding block 123 moves into the slots 13 of the two sets of connecting pipe bodies 1, thus completing the installation of the two sets of connecting pipe bodies 1. Next, the rotating block 125 is pulled and rotated, causing one end of the rotating block 125 to rotate above the knob 121. When the rotating block 125 is loosened, the knob 121 is engaged inside the rotating block 125. At the same time, the two ends of the connecting pipe body 1 adopt a multi-segment stepped cylindrical structure, which is interference-fitted with the water pump inlet and outlet and the pipeline end. The mating surface is provided with an annular sealing groove for embedding O-rings or fluororubber gaskets to achieve multi-level sealing, improve connection reliability and pull-out resistance. The threaded groove 11 inside the connecting pipe body 1 makes the fluid conduction more circulated and the heat dissipation better when the flow is divided into multiple segments, and the cold water circulation heat dissipation is more controllable.

[0034] Example 2: To address the problem that existing pump connecting pipes have poor compressive strength, leading to pipe blockage due to compression during use, this embodiment discloses the following technical solution, specifically as follows: Figures 6-10As shown, the support frame 211 has a card interface 22 fixedly connected internally, and the sleeve 2 has a pressure-resistant ring 212 fixedly connected internally. Multiple sets of pressure-resistant rings 212 are provided. Multiple sets of fixing balls 213 are fixedly connected to the outer side of the pressure-resistant rings 212. A connecting rod 214 is fixedly connected between two sets of fixing balls 213. A friction block 215 is fixedly connected to the outer side of the connecting rod 214. A packaging body 216 is fixedly connected to the outer side of the connecting rod 214. A fixing ring 23 is fixedly connected to the outer side of the sleeve 2. A friction pad 231 is fixedly connected inside the fixing ring 23, and a protrusion 232 is fixedly connected to the outer side of the fixing ring 23. During use, the sleeve... The internal receiving block 21 and support frame 211 provide initial pressure resistance for the sleeve pipe 2. Meanwhile, the snap-fit ​​interface 22 inside the support frame 211 works with the receiving block 21 to improve pressure resistance. The pressure-resistant ring 212 and the fixed ball 213 connected to the pressure-resistant ring 212 improve the crack resistance of the sleeve pipe 2, preventing cracking during use. The friction block 215 and packaging body 216 improve the stability of the connection between the connecting rod 214 and the pressure-resistant ring 212. At the same time, the fixed ring 23 makes the connection between the sleeve pipe 2 and the connecting pipe body 1 more stable, thus improving leak-proof performance.
