Description

Technical Field

[0001] This utility model belongs to the field of elevator waste heat recovery technology, and in particular relates to elevator waste heat recovery devices. Background Technology

[0002] Elevator waste heat recovery devices are energy-saving equipment designed based on the operating characteristics of elevators. Their core principle is to capture the excess heat energy generated by the elevator during operation, which would otherwise be directly discharged into the environment through the heat dissipation system. Through core components such as heat exchangers and circulation pipelines, this waste heat is collected, converted, and transferred, and then the treated heat energy is rationally utilized for domestic hot water supply or auxiliary heating in the building. This achieves "waste heat reuse" during elevator operation, reducing elevator heat dissipation energy consumption and overall building energy consumption while improving comprehensive energy utilization efficiency. It is a system with both energy-saving and environmental protection value.

[0003] However, in the existing equipment, the connection between the waste heat recovery pipe and the circulation pipeline is achieved by bolts and nuts. This connection method not only requires more manpower and time costs during installation and subsequent maintenance, but also the bolts are prone to loosening under long-term exposure to alternating hot and cold shocks, which may have a potential impact on the reliability of the pipeline connection and the continuous operation of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an elevator waste heat recovery device. By setting up a quick-release part, it solves the problem that when the waste heat recovery pipe is connected to the circulation pipe, the bolt and nut are used to achieve fastening. This connection method not only requires more manpower and time costs during installation and subsequent maintenance, but also the bolts are prone to loosening under long-term exposure to alternating hot and cold shocks, which may have a potential impact on the reliability of the pipeline connection and the continuous operation of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an elevator waste heat recovery device, comprising an elevator traction machine and a waste heat recovery pipe installed on the elevator traction machine. A circulation pipeline is provided on the back of the waste heat recovery pipe. Several fixing holes are provided on the waste heat recovery pipe and the circulation pipeline. The device further includes: quick-release parts, of which several quick-release parts are disposed within the fixing holes; buffer parts, of which several buffer parts are disposed on the quick-release parts; each quick-release part includes a quick-release assembly installed within the fixing hole; and a limiting component installed within the quick-release part. The quick-release assembly includes a screw slidably connected in a fixed hole. The outer wall of the screw has a movable ring with two disassembly grooves and two limiting grooves. Both disassembly grooves communicate with the fixed hole. A limiting rod is fixedly connected to the outer wall of the screw, and the limiting rod is slidably connected to the two disassembly grooves. The limiting rod is adapted to the two limiting grooves. A limiting component is provided on the screw. The movable ring is both slidably and rotatably connected to the outer wall of the screw. The limiting component includes a nut threadedly connected to the outer wall of the screw, with the front side of the nut contacting a limiting insert ring.

[0007] Furthermore, the buffer section includes a balancing assembly mounted on the movable ring; and a buffer assembly disposed on the movable ring.

[0008] Furthermore, the limiting component includes a limiting groove formed on the screw, a limiting ring slidably connected in the limiting groove, and several positioning holes formed on the circulation pipeline. The front end of each limiting ring extends into several positioning holes and is slidably connected to several positioning holes. The limiting groove on the screw provides sliding guidance for the limiting ring to ensure its smooth movement. The front end of the limiting ring extends into several positioning holes in the circulation pipeline. The appropriate positioning hole can be selected according to the relative position of the screw and the circulation pipeline to achieve quick locking and prevent relative rotation or displacement between the two during use.

[0009] Furthermore, the balancing component includes a mounting groove on the back of the movable ring. Two sliding frames are slidably connected within the mounting groove. Each sliding frame is hinged with a connecting rod. A connecting member is provided on each connecting rod. The connecting member includes a fixed frame on the back of the movable ring. The ends of the two connecting rods away from the sliding frames are hinged to the fixed frame. A buffer plate is fixedly connected to the back of the fixed frame. The buffer plate contacts the waste heat recovery pipe. The two sliding frames in the mounting groove on the back of the movable ring cooperate with the hinged connecting rods. The fixed frame drives the buffer plate to contact the waste heat recovery pipe, which can adapt to the curvature of the waste heat recovery pipe and ensure that the buffer plate fits tightly.

[0010] Furthermore, the buffer assembly includes two dampers fixedly connected in the mounting groove. The ends of the two dampers that are close to each other are fixedly connected to two sliding frames. Springs are wound around the outer walls of the two dampers. One end of each spring is fixedly connected to the mounting groove, and the other end of each spring is fixedly connected to the two sliding frames. The dampers in the mounting groove can effectively slow down the movement speed of the sliding frames and prevent the buffer plate from rigidly colliding with the waste heat recovery pipe due to the rapid sliding of the sliding frames caused by external forces. The springs on the outer walls of the dampers can provide elastic support and push the sliding frames to reset after they are moved by force. At the same time, they further buffer the impact force and enhance the protection effect on the waste heat recovery pipe.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a quick-release part, when using it, first put the waste heat recovery pipe on the elevator traction machine, then connect the waste heat recovery pipe and the circulation pipe. When connecting, ensure that the sealing ring of the circulation pipe and the sealing groove of the waste heat recovery pipe are compatible to prevent leakage. Then, insert one end of the screw into the corresponding fixing holes of the two and completely penetrate through them. Align the movable ring disassembly groove with the screw limit rod, put on the movable ring and lock it in place. Then rotate the movable ring so that the movable ring limit groove and the limit rod are compatible to limit one end of the screw. Next, at the other end of the screw, insert the limit ring into the screw limit slide groove, and let the limit ring insert rod be inserted into the positioning hole of the circulation pipe to prevent the screw from rotating on its own. Finally, screw in the nut to complete the fixation. This setting can quickly complete the connection and fixation of the two, simplify the installation process, ensure the stability of the connection, and avoid the problem of easy loosening of traditional bolt connections.

[0013] 2. By setting up a buffer section, when the screw and movable ring are used to fix the waste heat recovery pipe and circulation pipe, the movable ring is subjected to compressive force. Because there are two sliding frames on the movable ring, and the other end of the connecting rod of the sliding frame is hinged to the fixed frame on the buffer plate, when the movable ring and the buffer plate are subjected to compression together, the two sliding frames will slide in opposite directions on the movable ring in conjunction with the connecting rod and the fixed frame, while compressing the damper and spring in the mounting groove. This process can provide buffer space for the screw, reducing the impact of the elevator traction machine's working vibration on the screw fixing effect. This setting can effectively offset vibration stress, prevent the screw from loosening due to long-term vibration, further extend the service life of the connection structure, and ensure the overall stability and safety of the device operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 As shown, this utility model is an elevator waste heat recovery device, including an elevator traction machine 111 and a waste heat recovery pipe 112 installed on the elevator traction machine 111. A circulation pipe 113 is provided on the back of the waste heat recovery pipe 112. Several fixing holes 114 are provided on the waste heat recovery pipe 112 and the circulation pipe 113. It also includes: quick-release parts 2, which are provided in several locations and are all installed in the fixing holes 114; and buffer parts 3, which are provided in several locations and are all installed on the quick-release parts 2.

[0026] The quick-release part 2 includes a quick-release assembly 21, which is installed in the fixing hole 114; and a limiting assembly 22, which is installed on the quick-release assembly 21. The quick-release assembly 21 includes a screw 211 slidably connected in the fixing hole 114. The outer wall of the screw 211 is provided with a movable ring 212. Each movable ring 212 has two disassembly grooves 213 and two limiting grooves 214. Both disassembly grooves 213 communicate with the fixing hole 114. A limiting rod 215 is fixedly connected to the outer wall of the screw 211. The limiting rod 215 is slidably connected to the two disassembly grooves 213 and is adapted to the two limiting grooves 214. A limiting element is provided on the screw 211. The movable ring 212 is both slidably and rotatably connected to the outer wall of the screw 211. The limiting component 22 includes a limiting groove 221 opened on the screw 211, and a limiting insert ring 222 is slidably connected in the limiting groove 221. Several positioning holes 223 are opened on the circulation pipe 113. The front end of each limiting insert ring 222 extends into the several positioning holes 223 and is slidably connected to the several positioning holes 223. The limiting component includes a nut 216 threadedly connected to the outer wall of the screw 211. The front side of the nut 216 contacts the limiting insert ring 222. By setting the quick release part 2, in use, the waste heat recovery pipe 112 can be first sleeved on the elevator traction machine 111 to complete the sleeve. After the setup is complete, the connection between the waste heat recovery pipe 112 and the circulation pipe can be carried out. During the connection process, it is necessary to ensure that the sealing ring on the circulation pipe matches the sealing groove on the waste heat recovery pipe 112. This design can effectively prevent leakage at the interface. Then, insert one end of the screw 211 into the corresponding fixing hole 114 on the waste heat recovery pipe 112 and the circulation pipe, ensuring that the screw 211 completely penetrates the fixing hole 114. Next, align the two disassembly grooves 213 on the movable ring 212 with the limiting rod 215 on the screw 211, so that the movable ring 212 can be smoothly fitted onto the screw 211 and locked in place. After locking, rotate the movable ring 212 to allow the movable ring 212 to... The two limiting grooves 214 are adapted to the limiting rods 215 of the screw 211, thereby limiting one end of the screw 211 that passes through. Then, at the other end of the screw 211, the limiting ring 222 is inserted into the limiting groove 221 on the screw 211, while ensuring that the rod on the limiting ring 222 is inserted into the multiple positioning holes 223 on the circulation pipe 113, thereby limiting the screw 211 and preventing it from rotating. Finally, the nut 216 is screwed in to complete the fixation. With this setting, the connection and fixation of the waste heat recovery pipe and the circulation pipe can be completed quickly, greatly simplifying the installation process, while ensuring the stability of the connection structure and avoiding the problem of easy loosening of traditional bolt connections.

[0027] The buffer section 3 includes a balancing assembly 31, which is mounted on the movable ring 212; and a buffer assembly 32, which is also mounted on the movable ring 212. The balancing assembly 31 includes a mounting groove 311 formed on the back of the movable ring 212, in which two sliding frames 312 are slidably connected. Each sliding frame 312 is hinged with a connecting rod 313, and a connector is provided on the connecting rod 313. The buffer assembly 32 includes two dampers 321 fixedly connected in the mounting groove 311, with the ends of the two dampers 321 close to each other. Both are fixedly connected to two sliding frames 312. Springs 322 are wound around the outer walls of both dampers 321. One end of each spring 322 is fixedly connected to the mounting groove 311, and the other end is fixedly connected to both sliding frames 312. The connecting component includes a fixed frame 314 located on the back of the movable ring 212. The ends of both connecting rods 313 away from the sliding frame 312 are hinged to the fixed frame 314. A buffer plate 315 is fixedly connected to the back of the fixed frame 314. The buffer plate 315 contacts the waste heat recovery pipe 112. The buffer section 3 is provided. When the screw 211 and the movable ring 212 are used to fix the waste heat recovery pipe 112 and the circulation pipe 113, the movable ring 212 will be subjected to a compressive force. Since the movable ring 212 is provided with two slidable sliding frames 312, and each of the two sliding frames 312 is hinged with a connecting rod 313, and the other end of the two connecting rods 313 is hinged to the fixed frame 314 on the buffer plate 315, when the movable ring 212 and the buffer plate 315 are subjected to compression together, the two sliding frames 312 will cooperate with their respective connected connecting rods. 313 and the fixed frame 314 slide in opposite directions on the movable ring 212, and at the same time compress the damper 321 and spring 322 in the mounting groove 311. This process can provide a certain buffer space for the screw 211 after installation, thereby reducing the impact of the vibration generated by the elevator traction machine 111 on the fixing effect of the screw 211. Through this setting, the stress caused by vibration can be effectively offset, and the screw can be prevented from loosening due to long-term vibration, further extending the service life of the connection structure and ensuring the overall stability and safety of the device.

[0028] One specific application of this embodiment is: Elevator traction machine 111: It is the power equipment of the elevator, usually composed of components such as motor, brake, and traction sheave. It pulls or stops the elevator car by the friction between the traction rope and the groove of the traction sheave. Model: BPM450 is a steel belt elevator traction machine, with first-class energy efficiency, suitable for home elevators, and has a load capacity of 320-630k.

[0029] Elevator waste heat recovery and circulation system: This is an energy-saving system that relies on the heat dissipation characteristics of core power components such as elevator traction machines. It collects the redundant heat generated during operation through a specific heat exchange device and converts this heat into usable energy such as hot water, which can then be reused for domestic hot water supply, elevator machine room or car heating, and other scenarios.

[0030] In use, the waste heat recovery pipe 112 can be first fitted onto the elevator traction machine 111. After fitting, the waste heat recovery pipe 112 can be connected to the circulation pipeline. During the connection process, it is necessary to ensure that the sealing ring on the circulation pipeline matches the sealing groove on the waste heat recovery pipe 112. This design can effectively prevent leakage at the interface. Then, insert one end of the screw 211 into the corresponding fixing hole 114 on the waste heat recovery pipe 112 and the circulation pipeline, and ensure that the screw 211 completely penetrates the fixing hole 114. Next, align the two disassembly grooves 213 on the movable ring 212 with the limiting rod 215 on the screw 211. This allows the movable ring 212 to smoothly fit onto the screw 211 and engage. After engagement, the movable ring 212 is rotated so that the two limiting grooves 214 on the movable ring 212 match the limiting rods 215 on the screw 211, thus limiting the end of the screw 211 that passes through. Next, at the other end of the screw 211, the limiting insert ring 222 is inserted into the limiting slide groove 221 on the screw 211, while ensuring that the insert rod on the limiting insert ring 222 is inserted into the multiple positioning holes 223 on the circulation pipe 113. This limits the screw 211 and prevents it from rotating. Finally, the nut 216 is screwed in to complete the fixation. This setting... This allows for rapid connection and fixation of the waste heat recovery pipe and circulation pipeline, significantly simplifying the installation process while ensuring the stability of the connection structure and avoiding the loosening problem of traditional bolt connections. When the screw 211 and the movable ring 212 are used to fix the waste heat recovery pipe 112 and the circulation pipeline 113, the movable ring 212 will be subjected to compressive force. Since the movable ring 212 has two slidable sliding frames 312, and each of the two sliding frames 312 is hinged with a connecting rod 313, and the other end of the two connecting rods 313 is hinged to the fixed frame 314 on the buffer plate 315, the movable ring 212 and the buffer plate 315 together... When subjected to compression, the two sliding frames 312 will cooperate with their respective connected connecting rods 313 and fixed frames 314 to slide in opposite directions on the movable ring 212, and at the same time exert a compression effect on the damper 321 and spring 322 in the mounting groove 311. This process can provide a certain buffer space for the screw 211 after installation, thereby reducing the impact of the vibration generated by the elevator traction machine 111 during operation on the fixing effect of the screw 211. Through this setting, the stress caused by vibration can be effectively offset, preventing the screw from loosening due to long-term vibration, further extending the service life of the connection structure, and ensuring the overall stability and safety of the device.
