Description

Technical Field

[0001] The present invention belongs to the technical field of environmental sanitation equipment, and particularly relates to an underground garbage station. Background Art

[0002] An underground garbage station is a device that hides the garbage bin underground for garbage treatment. This device is a domestic garbage collection, transfer, and transportation device that integrates airtightness, environmental protection, and high efficiency, and solves problems such as peculiar smell, stench, and breeding of mosquitoes and flies existing in the open operation mode of conventional garbage compressors in the past. The underground garbage compressor belongs to the supporting equipment of the garbage transfer station.

[0003] In the related prior art, an underground garbage station usually adopts a compression station, which requires digging a large-volume pit, resulting in a large floor area. After the garbage bin is compressed to full load, the garbage bin needs to be replaced, so the overall cost is relatively high. Moreover, since the garbage compression station compresses and stores garbage, after the garbage bin is full, a relatively large lifting power is required, resulting in high costs and relatively low efficiency. Summary of the Invention

[0004] The present invention aims to at least solve the above technical problems existing in the prior art. For this purpose, the present invention provides an underground garbage station, which can reduce the equipment cost and improve the operation efficiency.

[0005] The underground garbage station according to an embodiment of the present invention includes: A foundation pit, which is arranged at the placement site; A lifting platform, which is arranged at the bottom of the foundation pit; A garbage bin, which is rotatably arranged on the lifting platform. The garbage bin has a receiving posture and a dumping posture. When the garbage bin is in the receiving posture, it can receive garbage. When the garbage bin is in the dumping posture, it can dump the garbage. An inclination angle is provided on one side of the garbage bin close to the rotation center, so that the cavity of the garbage bin has a structure with a larger upper part and a smaller lower part; A flipping drive mechanism, which is arranged between the garbage bin and the lifting platform and is used to control the switching of the garbage bin between the receiving posture and the dumping posture.

[0006] The underground garbage station according to an embodiment of the present invention has at least the following beneficial effects: In the underground garbage station of this embodiment, the garbage box body is rotatably arranged on the lifting platform. During the use of putting in and collecting garbage, the lifting platform is located at the bottom of the foundation pit. After reaching the set storage capacity, the garbage box body can be pushed out of the foundation pit by the lifting platform, and then the garbage box body is flipped to the dumping posture, so that the collected garbage can be dumped into the collection vehicle. Since the garbage box body only collects garbage and does not compress garbage, the corresponding driving power requirement is relatively low. At the same time, the cavity of the garbage box body has a structure with a larger upper part and a smaller lower part. Under the action of the inclination angle, the center of gravity of the garbage box body will be at the middle position in the height direction of the garbage box body, which not only avoids the large weight caused by too large a capacity, but also facilitates the flipping and switching of the posture.

[0007] Therefore, the underground garbage station in this embodiment can reduce the equipment cost, improve the operation efficiency, and has a simple and reliable structure.

[0023] In the description of the present invention, the description with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0024] Referring to Figures 1 to 6 , an embodiment of the present invention provides a buried garbage station, including: A foundation pit 400, which is arranged at the placement site; A lifting platform 200, which is arranged at the bottom of the foundation pit 400; A garbage box body 100, which is rotatably arranged on the lifting platform 200. The garbage box body 100 has a receiving posture and a dumping posture. When the garbage box body 100 is in the receiving posture, it can receive garbage. When the garbage box body 100 is in the dumping posture, it can dump the garbage. An inclination angle is set on one side of the garbage box body 100 close to the rotation center, so that the cavity of the garbage box body 100 has a structure with a larger upper part and a smaller lower part; A flipping drive mechanism, which is arranged between the garbage box body 100 and the lifting platform 200 and is used to control the switching of the garbage box body 100 between the receiving posture and the dumping posture.

[0025] It is understandable that the foundation pit 400 is dug at the placement site, and the corresponding foundation structure can be constructed as needed.

[0026] The lifting platform 200 is arranged at the bottom of the foundation pit 400 and can realize the lifting and lowering of the garbage box body 100 through lifting adjustment.

[0027] An inclination angle is set on one side of the garbage box body 100 close to the rotation center, so that the internal cavity has a structure with a larger upper part and a smaller lower part, that is, in the direction from top to bottom, the inner cavity of the garbage box body 100 moves in the direction away from the rotation center. Therefore, the total amount of garbage stored at the bottom of the garbage box body 100 will be less than the total amount of garbage stored in the upper part of the garbage box body 100, which can balance the center of gravity of the garbage box body 100 and make it in the middle position in the height direction, facilitating tipping.

[0028] In the buried garbage station of this embodiment, the garbage box body 100 is rotatably arranged on the lifting platform 200. During the use of putting and collecting garbage, the lifting platform 200 is located at the bottom of the foundation pit 400. After reaching the set storage capacity, the garbage box body 100 can be pushed out of the foundation pit 400 through the lifting platform 200, and then the garbage box body 100 is flipped to the tipping posture, and the collected garbage can be dumped into the collection vehicle. Since the garbage box body 100 only collects garbage and does not compress garbage, the corresponding driving power requirement is relatively low. At the same time, the cavity of the garbage box body 100 has a structure with a larger upper part and a smaller lower part. Under the action of the inclination angle, the center of gravity of the garbage box body 100 will be in the middle position in the height direction of the garbage box body 100, which not only avoids the large weight caused by too large a capacity, but also facilitates flipping and switching postures.

[0029] Therefore, the buried garbage station in this embodiment can reduce equipment costs, improve operation efficiency, and has a simple and reliable structure.

[0030] In some embodiments of the present invention, a first support frame 201 extends upward at the front end of the lifting platform 200, and the rear end surface of the first support frame 201 extends backward from top to bottom, and its inclination angle is the same as the inclination angle of the front end surface of the garbage box body 100. The front end of the garbage box body 100 is rotatably connected to the upper end of the first support frame 201, and the front end surface of the garbage box body 100 is attached to the rear end surface of the first support frame 201.

[0031] With the structural arrangement of this embodiment, the garbage box body 100 is rotatably installed through the first support frame 201, and its upper end can be flipped upward around the first support frame 201 from the state of horizontally receiving garbage to the state of tilting toward one side for garbage dumping. Moreover, the rear end surface of the first support frame 201 is provided with an inclination angle, that is, the first support frame 201 has a structure with a larger upper part and a smaller lower part, which can effectively ensure the structural strength of the first support frame 201, and further ensure the support stability for the garbage box body 100.

[0032] Meanwhile, since the front end face of the garbage box body 100 is inclined, it will be subjected to a downward pressure during the process of storing garbage. The first support frame 201 of this embodiment can cooperate to support the front end face of the garbage box body 100, ensuring the stability of the side wall of this part, helping to reduce the strength requirements for the side wall of this part, and thus reducing the production cost.

[0033] Combined with Figure 2 and Figure 3 , two triangular frames 2011 are symmetrically arranged on the left and right of the first support frame 201, and multiple beam bodies are arranged between the two triangular frames 2011 for reinforcement. An installation space is formed between the two triangular frames 2011.

[0034] In some embodiments of the present invention, the flipping drive mechanism includes two flipping oil cylinders 103, and both of the two flipping oil cylinders 103 are arranged in the installation space. The lower end of the flipping oil cylinder 103 is connected to the first support frame 201, and the upper end is connected to the front end face of the garbage box body 100.

[0035] In this embodiment, by arranging the flipping oil cylinder 103 in the installation space, not only can the flipping driving force be ensured, but also it can be avoided from being close to the side wall of the foundation pit 400, and the flipping oil cylinder 103 can be protected.

[0036] Furthermore, the flipping oil cylinder 103 is located behind the rotational installation position of the garbage box body 100. And, the upper end of the flipping oil cylinder 103 is located behind its lower end. In this way, when the flipping oil cylinder 103 extends, the garbage box body 100 can be quickly flipped upwards, which can improve the dumping efficiency.

[0037] In some embodiments of the present invention, the lifting platform 200 is further provided with a second support frame 202. The second support frame 202 is connected to the rear end of the first support frame 201 and extends horizontally backward, and the bottom of the garbage box body 100 abuts against the second support frame 202.

[0038] It can be understood that in this embodiment, the lifting platform 200 uses the first support frame 201 and the second support frame 202 to jointly support the garbage box body 100, which can effectively ensure the support stability of the garbage box body 100.

[0039] In some embodiments of the present invention, there is a spacing between the first support frame 201 and the front end of the lifting platform 200. Usually, the peripheral dimension of the lifting platform 200 matches the dimension of the foundation pit 400. In this embodiment, by setting the first support frame 201 to move backward a certain distance relative to the front end of the lifting platform 200, it can effectively avoid the interference between the first support frame 201 and the foundation pit 400, and can reduce the precision requirements of the dimensions.

[0040] And the upper end of the first support frame 201 extends forward to form a convex part 2012. The protruding distance of the convex part 2012 is less than the distance that the first support frame 201 retracts backward relative to the front end of the lifting platform 200, so as to ensure that the convex part 2012 will not interfere with the foundation pit 400.

[0041] The garbage box body 100 is rotatably connected to the convex part 2012, and there is a smooth transition between the convex part 2012 and the rear end face of the first support frame 201.

[0042] It can be understood that since the garbage box body 100 needs to be flipped forward to the dumping posture to dump the garbage from the front end, in this embodiment, the garbage box body 100 is connected to the convex part 2012 and can move forward relative to the first support frame 201 in the dumping posture, so as to facilitate docking with the transport vehicle and reduce the possibility of garbage leakage.

[0043] At the same time, the garbage box body 100 is connected to the convex part 2012, which is beneficial to increasing the distance between its own rotation center and the connection position of the tipping oil cylinder 103, facilitating the tipping oil cylinder 103 to push the garbage box body 100 to tip, reducing the driving force requirement of the tipping oil cylinder 103, and being beneficial to reducing the production cost.

[0044] Meanwhile, there is a smooth transition between the convex part 2012 and the rear end face of the first support frame 201, that is, there is no tip structure at the upper end of the first support frame 201, which can ensure the smooth tipping of the garbage box body 100 and there will be no interference problem with the garbage box body 100.

[0045] In some embodiments of the present invention, a box cover 300 is rotatably provided at the upper end of the garbage box body 100, and the rotational connection position of the box cover 300 and the rotational connection position of the garbage box body 100 relative to the lifting platform 200 are located at opposite ends of the garbage box body 100.

[0046] It can be understood that since the garbage box body 100 is rotatably connected to the lifting platform 200 at the front end to dump the garbage forward into the transport vehicle, the box cover 300 is rotatably connected to the rear end of the garbage box body 100 so that the upper end of the garbage box body 100 can be opened backward to dump the garbage.

[0047] In some embodiments of the present invention, a discharge port 102 is provided on one side of the upper end of the garbage box body 100 near its rotation center. The height of the discharge port 102 is lower than the opening 101 at the top of the garbage box body 100. The lower edge of the discharge port 102 is connected to the front end face of the garbage box body 100. With the structural arrangement of this embodiment, when the garbage box body 100 is switched to the dumping posture, it can be quickly discharged from the discharge port 102 along the front end face.

[0048] It is understandable that the discharge port 102 communicates with the top opening 101 of the garbage box body 100. It can be understood that the front end of the top opening 101 of the garbage box body 100 extends downward to the front end face of the garbage box body 100.

[0049] With the above structural arrangement, pointed parts will be formed at the upper ends of the left and right side walls of the garbage box body 100. When the box cover 300 is closed on the upper end of the garbage box body 100, it will fit with it, and the sealing effect is better compared with the form of flat closing.

[0050] In some embodiments of the present invention, the upper end of the garbage box body 100 is at the same height as or close to the upper end of the foundation pit 400, and a garbage disposal bin 301 is convexly provided at the upper end of the garbage box body 100.

[0051] With this arrangement, the garbage box body 100 will not damage the landform and is conducive to integrating into the surrounding environment. And the convexly provided garbage disposal bin 301 facilitates the surrounding residents or other users to dump garbage into the garbage box body 100.

[0052] It is understandable that the garbage disposal bin 301 is provided on the box cover 300. When the garbage in the garbage box body 100 is dumped, the box cover 300 and the garbage disposal bin 301 move backward together.

[0053] In some embodiments of the present invention, the buried garbage station further includes a billboard. The billboard is provided on one side of the foundation pit 400, and the billboard is integrally provided with a control panel for controlling the operation of the garbage box body 100.

[0054] In this embodiment, by combining the control panel with the billboard, the control panel can be set at a suitable height by using the billboard, and at the same time, the setting of two floor-standing facilities can be avoided, saving the floor area.

[0055] Among them, the billboard can be used for the relevant description of the garbage disposal categories, or used as a public welfare advertisement, or a commercial advertisement.

[0056] In some embodiments of the present invention, a plurality of foundation pits 400 are arranged side by side for the buried garbage station. The control panel is located at the position between two adjacent foundation pits 400 and can at least control the operation of two adjacent garbage box bodies 100. The billboards are arranged in one-to-one correspondence with the foundation pits 400, and a solar lighting component is provided above each billboard.

[0057] In this embodiment, the billboard is provided at the rear end of the foundation pit 400. By setting the solar lighting component, it can not only provide lighting for the advertising space using clean energy, but also provide basic lighting for the garbage box body 100 at night, facilitating users to dump garbage.

[0058] It is understood that the solar lighting assembly includes a solar panel, a control circuit and a lighting fixture, wherein the control circuit is activated based on the lighting conditions to ensure brightness.

[0059] In some embodiments of the present invention, the waste box 100 is made of stainless steel.

[0060] In some embodiments of the present invention, the box cover 300 is rotatably connected to the side wall of the foundation pit 400 to further reduce weight and lower the requirements for the lifting platform 200 and the turning drive mechanism.

[0061] In some embodiments of the present invention, a sewage tank and a water pump are provided at the bottom of the foundation pit 400 to collect the incoming rainwater and pump it out.

[0062] Reference Figure 5 and Figure 6 In some embodiments of the present invention, the lifting platform 200 is provided with a scissor-type lifting assembly, which uses a scissor-type structure to achieve lifting. Specifically, it includes a first group of scissor rods and a second group of scissor rods. Each group of scissor rods is respectively provided with two first scissor rods 203 and two second scissor rods 204. The middle position of the first scissor rods 203 and the second scissor rods 204 is hinged to form a scissor-type structure. Among them, in the first scissor rods 203 and the second scissor rods 204 located at the bottom, the lower end of the first scissor rod 203 is relatively fixed to the front end of the bottom of the foundation pit 400, and the lower end of the second scissor rod 204 is provided with a roller 2031. When the first scissor rods 203 and the second scissor rods 204 are hydraulically controlled to rotate and lift relative to each other, the roller 2031 rolls forward. After the garbage bin 100 is lifted, the lifting assembly is located directly below the first support frame 201.

[0063] Since the garbage bin 100 needs to be flipped forward to dump the garbage, the structural arrangement of this embodiment allows the center of gravity of the garbage bin 100 to be located near the lifting assembly, which helps ensure that the garbage bin 100 is effectively supported during the dumping process and avoids shaking.

[0064] Reference Figure 6 On this basis, the bottom of the lifting platform 200 is provided with a limiting guide rail 2032 for the forward and backward movement of the roller 2031. A push block 2033 is slidably mounted on the rear section of the limiting guide rail 2032, and a spring is mounted on the rear end of the push block 2033. Furthermore, a first damping pad 2034 and a second damping pad 2035 are provided on the upper and lower sides of the front section of the limiting guide rail 2032. The distance between the first damping pad 2034 and the second damping pad 2035 gradually decreases from the back to the front. The first damping pad 2034 and the second damping pad 2035 are configured as elastically deformable structures, such as rubber structures.

[0065] With the structural arrangement of this embodiment, when the garbage bin body 100 is in the receiving posture, the pushing block 2033 is pushed backward by gravity to compress the spring. When it is necessary to dump the garbage, at the moment when the lifting assembly is lifted upward, the pushing block 2033 can assist the roller 2031 to play a promoting role, which can reduce the starting hydraulic shock of the lifting assembly.

[0066] When approaching the set height during lifting, the roller 2031 enters between the first damping pad 2034 and the second damping pad 2035, and the up and down assembly clearance of the roller 2031 can be eliminated through the first damping pad 2034 and the second damping pad 2035 to ensure the stability of the first support frame 201 during the dumping process. And during the flipping process of the garbage bin body 100, the impact brought by the change of gravity can be absorbed through the first damping pad 2034 and the second damping pad 2035, which is beneficial to extending the service life of the hydraulic system and the stability of the whole system.

[0067] When the lifting assembly descends, the first damping pad 2034 and the second damping pad 2035 can play a damping role to relieve the impact brought by the moment of starting to descend. And when it reaches the position of descent, the pushing block 2033 also plays a buffering role, which can relieve the collision impact caused when the lifting platform 200 reaches the position of descent. Therefore, the whole equipment runs more smoothly.

[0068] In order to reduce the friction force between the pushing block 2033 and the roller 2031, the pushing block 2033 can be set to a smooth structure or a structure with small friction force, such as a nylon structure.

[0069] To sum up, the underground garbage station in the present invention has the following advantages: 1. The concealed design of the underground garbage station reduces visual chaos and avoids problems such as peculiar smells and stains caused by traditional trash cans being exposed outdoors for a long time, improving the overall beauty and cleanliness of the city; 2. The garbage hopper of the underground garbage station is made of stainless steel and has characteristics such as fire resistance and corrosion resistance; 3. The bottom of the underground garbage station is provided with a sewage tank, and there will be no sewage leakage to affect the underground water source; 4. The underground garbage station is equipped with a hydraulic lift for dumping, making garbage transfer more convenient and labor-saving, and reducing the labor intensity during the transfer process; 5. The underground garbage station can be connected to the Internet of Things platform through the 4G Internet of Things system, and the garbage volume can be detected in real time, and an alarm can be sent through the mobile phone terminal for transfer to avoid garbage accumulation during the use of the equipment; 6.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
