Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of batteries, in particular to a standby battery for a vertical lift elevator and its installation structure. Background Art
[0002] In order to avoid the problem that a vertical lift elevator cannot operate normally in case of sudden power outage or other power system failures, standby batteries are often installed during the installation of vertical lift elevators. When the main power supply of the elevator suddenly interrupts, the standby battery can be quickly started to provide continuous power support for the elevator, ensuring that the elevator can complete necessary emergency operations and safely deliver passengers to the nearest floor. By installing standby batteries, the stability and reliability of the entire vertical lift elevator system are improved, and the safety and comfort of passengers taking the elevator are guaranteed.
[0003] Existing standby batteries for vertical lift elevators are usually installed in the hoistway wall. A suitable installation position is determined based on the structure of the hoistway wall, the layout of the elevator system, and the weight and size of the standby battery. Then, the mounting bracket is fixed to the hoistway wall by bolts. Finally, the elevator standby battery is fixed to the mounting bracket to realize the fixation of the standby battery on the hoistway wall. To reduce the dependence on the width of the hoistway wall during the installation of the elevator standby battery and simplify the installation process, the existing technology often installs the elevator standby battery at a position on the traction machine frame close to the traction machine brake, making use of the existing traction machine frame, eliminating the process of installing the mounting frame, simplifying the construction process, and at the same time, since the standby battery is not installed on the hoistway wall, it is not limited by the width of the hoistway wall.
[0004] However, in the existing technology, when the elevator standby battery is installed at the traction machine brake part, the heat generated by the operation of the traction machine will be transferred to the elevator standby battery. Due to the influence of high temperature, a series of adverse side reactions will occur inside the standby battery, such as the decomposition of the electrolyte and the corrosion of the electrode material, affecting the performance of the standby battery and shortening the service life of the standby battery. Summary of the Utility Model
[0005] An object of the utility model is to solve the problems in the existing technology that when the elevator standby battery is installed near the traction machine, the performance of the elevator standby battery is reduced and the service life is shortened under the influence of the temperature of the traction machine.
[0006] The utility model provides a standby battery for a vertical lift elevator, which is characterized in that it includes a battery box and a battery assembly installed in the battery box. The standby battery can be fixed at a position on the traction machine frame close to the traction machine brake. A plurality of heat dissipation fins are provided on the battery box. The plurality of heat dissipation fins include a first heat dissipation fin group close to the brake. The height of each heat dissipation fin in the first heat dissipation fin group gradually decreases from the middle of the battery box in the height direction to both sides in the height direction.
[0007] Further, a support leg is provided on one side of the battery box close to and parallel to the traction machine frame, so as to leave a gap between the backup battery and the traction machine frame.
[0008] Further, a shock absorption device is provided on one side of the battery box close to and parallel to the traction machine frame.
[0009] Further, a heat dissipation fan for blowing out the heat dissipated by the battery assembly to the outside of the battery box is provided on the battery box.
[0010] Further, a wind deflector for guiding the hot air blown out by the heat dissipation fan is provided on the battery box.
[0011] Further, the wind deflector is connected to the battery box through a hinge.
[0012] Further, an electromagnetic shielding material is sprayed on the battery box.

[0014] Further, the heat dissipation fan is arranged on one side of the battery box far from the traction machine frame and parallel to the traction machine frame.
[0015] Further, the length or width of the backup battery is not greater than the width of the traction machine frame.
[0016] The beneficial effects of the present utility model are as follows:
[0017] 1.

[0024] To make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application in conjunction with the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the convenience of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0025] The terms "including" and "having" and any variations thereof in the present application are intended to cover non - exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.
[0026] Referring to "embodiment" in this article means that specific features, structures, or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0027] The specific implementation manners of the backup battery 100 of the vertical lift elevator of the present utility model and its installation structure are as follows: The backup battery 100 is fixed on the elevator traction machine frame 1, the traction machine frame 1 is installed on the top of the elevator car, and the traction machine 2 is fixed on the traction machine frame 1. Since the two sides of the traction machine 2 in the prior art are asymmetric along the length direction, when the traction machine 2 is installed in the middle of the traction machine frame 1, a part of the remaining space will be left on one side of the traction machine frame 1 close to the brake 21, and the backup battery 100 of the present utility model is installed in this remaining space.
[0028] In one embodiment, heat dissipation fins 4 are provided on the battery box 3 to enhance the heat dissipation capacity of the backup battery 100. To increase the contact area between the heat dissipation fins 4 and the air, and thus enhance the heat dissipation capacity of the heat dissipation fins 4. When the backup battery 100 of the present utility model is installed on one side in the length direction of the traction machine frame 1 and close to the brake 21 of the traction machine 2, the brake 21 of the traction machine 2 and the middle part of the backup battery 100 in the height direction are at the same horizontal height, resulting in more heat being generated in the middle part of the backup battery 100 in the height direction. Therefore, in one embodiment, the height of the fins on the side close to the traction machine 2 gradually decreases from the middle in the height direction of the battery box 3 to both sides in the height direction. Since the heat dissipation fins 4 close to the position of the brake 21 have a higher height and a larger contact area with the air, the heat dissipation capacity is stronger.
[0029] Through the above solution, the heat dissipation capacity of the backup battery 100 is enhanced, the performance and service life of the backup battery 100 are improved, and the operation of the backup battery 100 is made more reliable.
[0030] In one embodiment, support feet 5 are provided on one side of the battery box 3 close to and parallel to the traction machine frame 1, leaving a gap between the backup battery 100 and the traction machine frame 1. The heat generated by the backup battery 100 dissipates from the gap, preventing the overheating of the bottom of the backup battery 100 from having an adverse effect on the performance of the backup battery 100.
[0031] To further improve the heat dissipation capacity of the backup battery 100, in one embodiment, a heat dissipation fan 6 is provided on the battery box 3. The turning on and off of the heat dissipation fan 6 can be controlled by a temperature sensor. When the internal temperature of the backup battery 100 is higher than the preset temperature value of the temperature sensor, the temperature sensor controls the heat dissipation fan 6 to turn on. When the internal temperature of the backup battery 100 drops below the preset temperature value, the temperature sensor controls the heat dissipation fan 6 to turn off. By providing the heat dissipation fan 6, the internal temperature of the backup battery 100 is further reduced.
[0032] Since the density of hot air is relatively low, when the internal temperature of the backup battery 100 rises, the hot air rises to the top side in the height direction of the backup battery 100. In one embodiment, the heat dissipation fan 6 is provided on one side of the battery box 3 away from and parallel to the traction machine frame 1, to fully discharge the internal hot air of the backup battery 100 to the outside, and to minimize the internal temperature of the backup battery 100.
[0033] By comprehensively using the above solutions, the internal temperature of the backup battery 100 is minimized, the situation that the internal temperature of the backup battery 100 is too high affecting its performance is avoided, the risk of thermal runaway of the backup battery 100 is reduced, and the service life of the backup battery 100 is extended.
[0034] To reduce the impact of the hot air blown by the cooling fan 6 on the traction machine 2, in one embodiment, a wind deflector 7 for guiding the hot air blown by the cooling fan 6 is provided on the battery box 3. The wind deflector 7 is arranged on the side of the cooling fan 6 close to the traction machine 2. By providing the wind deflector 7, it is avoided that a large amount of the air blown by the cooling fan 6 flows towards the side of the traction machine 2, resulting in overheating of the traction machine 2 and affecting the performance of the traction machine 2. In order to adjust the angle of the wind deflector 7 and guide the hot air blown by the cooling fan 6 in a direction away from the traction machine 2. In one embodiment, the wind deflector 7 and the battery box 3 can be connected by a torque hinge 8, and while the angle of the wind deflector 7 can be adjusted, the wind deflector 7 can be fixed at a specific angle.
[0035] Since the backup battery 100 of the present utility model can be installed on the traction machine frame 1, the vibration generated during the operation of the traction machine 2 will be transmitted from the traction machine frame 1 to the backup battery 100. To avoid adverse effects of the vibration on the performance of the backup battery 100. Therefore, a shock absorption device can be provided between the backup battery 100 and the traction machine frame 1 of the present utility model. In one embodiment, the shock absorption device is a shock pad 9 provided on the side of the battery box 3 where the support feet 5 are provided. The shock pad 9 can be entirely laid on the bottom of the backup battery 100 or partially laid on the bottom of the backup battery 100, separating the bottom of the backup battery 100 from the traction machine frame 1. In addition, the shock pad 9 can also be provided under the support feet 5. In other embodiments, the backup battery 100 can also be fixed on an existing spring shock absorber, and the spring shock absorber is fixed on the traction machine frame 1. By providing a shock absorption device at the bottom of the backup battery 100, the impact of the vibration generated by the traction machine 2 on the backup battery 100 is reduced, ensuring the stability of the performance of the backup battery 100.
[0036] The backup battery 100 and the traction machine frame 1 can be fixed in various ways. In one embodiment, a first through hole is provided at the bottom of the battery box 3 of the backup battery 100, and a bolt passes through the first through hole and is connected to a second through hole preset on the traction machine frame 1 to fix the backup battery 100 on the traction machine frame 1. In another embodiment, a through third through hole is provided on the support feet 5 at the bottom of the battery box 3. After the bolt passes through the first through hole and the third through hole, it is connected to the second through hole preset on the traction machine frame 1. When the shock pad 9 is provided under the support feet 5, a fourth through hole penetrating along the thickness direction of the shock pad 9 is provided on the shock pad 9. After the bolt passes through the first through hole, the third through hole, and then the fourth through hole on the shock pad 9, it is connected to the second through hole preset on the traction machine frame 1. Other ways capable of fixing the backup battery 100 on the traction machine frame 1 all fall within the protection scope of the present utility model and will not be elaborated herein.
[0037] To ensure that the backup battery 100 can be installed more firmly on the traction machine frame 1, in one embodiment, the length of the backup battery 100 is not greater than the width of the traction machine frame 1. When the backup battery 100 is installed on the traction machine frame 1, the length direction of the backup battery 100 is perpendicular to the width direction of the traction machine frame 1. In another embodiment, the width of the backup battery 100 is not greater than the width of the traction machine frame 1. When the backup battery 100 is installed on the traction machine frame 1, the width direction of the backup battery 100 is perpendicular to the length direction of the traction machine frame 1. This reduces the overhanging part of the backup battery 100 after it is installed on the traction machine frame 1 and enhances the safety and stability of the backup battery 100 installed on the traction machine frame 1.
[0038] Since the backup battery 100 of the present utility model is installed beside the traction machine frame 1, the traction machine 2 will emit electromagnetic waves during operation. To prevent the backup battery 100 from being in an electromagnetic environment for a long time and accelerating the aging process of the internal components of the battery, in one embodiment, an electromagnetic shielding material is sprayed on the battery box 3. In other embodiments, a shielding net made of metals such as copper and aluminum can also be used to cover the backup battery 100, and the thickness of the shielding cover is close to the skin depth of the electromagnetic wave, so as to achieve a better electromagnetic shielding effect. By spraying an electromagnetic shielding material on the battery box 3 or installing an electromagnetic shielding net, the backup battery 100 is prevented from accelerating aging due to long-term exposure to electromagnetic waves, and the durability of the backup battery 100 is improved.
[0039] In one embodiment, a handle 10 for facilitating the movement of the backup battery 100 is provided on the battery box 3. When it is necessary to move the backup battery 100, the backup battery is moved to a suitable position by lifting the handle 10.
[0040] The above-described embodiments merely represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
