Description

Technical Field

[0001] The invention belongs to the technical field of underground garbage cans, and in particular relates to a non-active power lifting underground garbage can device and a use method thereof. Background Art

[0002] With the acceleration of urbanization, the amount of urban garbage has increased dramatically. Traditional ground trash cans occupy public space, affect the appearance of the city, and are prone to produce odor and breed pests. Underground trash cans are usually designed to be half buried or fully buried underground, with only the delivery port exposed above the ground. This design not only saves ground space, but also effectively reduces the odor and visual pollution of garbage and prevents the breeding of mosquitoes. The use of underground trash cans helps to improve the environmental friendliness of urban garbage management, reduce the negative impact on the environment, and is in line with the concept of sustainable development.

[0003] Existing underground trash cans are generally driven to rise and fall by motors and electric hydraulic cylinders. However, in actual use, power outages of electrical equipment often occur. Sometimes it is due to a city power failure, and sometimes it is due to damage to the motor or electric hydraulic cylinder equipment or circuit damage. This causes the underground trash can to be unable to rise and fall for a period of time. In particular, when the motor or electric hydraulic cylinder equipment is damaged or the circuit is damaged, the underground trash can is difficult to repair when it cannot be raised. It is necessary to open a maintenance hole on the top platform for personnel to enter and exit, and the personnel must climb down to the foundation pit to carry out repairs. The operation process is difficult and very troublesome. Summary of the invention

[0004] In order to solve the shortcomings of the prior art, the present invention provides a non-active power lifting underground bucket device and a method of using the same. The present invention can lift the underground bucket device without power drive, effectively solving the problem that the underground bucket device cannot be lifted when the power is off.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is:

[0006] A device for lifting an underground bucket without active power comprises an underground foundation pit, an underground frame is installed in the underground foundation pit, at least one pneumatic support rod is installed on the underground frame, an underground bucket moving unit is fixedly installed on the travel rod of the pneumatic support rod, the underground bucket moving unit is vertically slidably installed on the underground frame, the underground bucket moving unit comprises a bottom platform, an underground bucket, a connecting frame and a top platform, the underground bucket is placed on the bottom platform, the bottom platform is connected to the top platform through the connecting frame, the top platform is located above the underground bucket, a feeding port for feeding garbage into the underground bucket is provided on the top platform, the travel rod of the pneumatic support rod has a thrust for pushing the underground bucket moving unit upward, a water tank is installed on the top platform, by filling or releasing water into the water tank, the gravity of the underground bucket moving unit is made greater than or less than the thrust of the pneumatic support rod, thereby causing the underground bucket moving unit to move up and down.

[0007] To optimize the above technical solutions, the specific measures taken also include:

[0008] A water storage tank body is arranged at the bottom of the above-mentioned buried foundation pit, and the water storage tank body is connected to the water tank through a water pump. Water is stored in the water storage tank body, and the water pump is used to pump the water in the water storage tank body into the water tank or pump the water in the water tank into the water storage tank body.

[0009] A water filter hole is arranged at the bottom of the buried barrel, and the water filter hole runs through the bottom of the buried barrel from top to bottom. A filter screen is installed in the water filter hole. A water receiving hole is arranged on the top of the water storage tank body, and the water filter hole and the water receiving hole are aligned up and down. The sewage in the buried barrel can be filtered through the water filter hole and then enter the water storage tank body.

[0010] The top platform is provided with a pedal-operated opening and closing cover plate, which can be opened and closed on the feeding port.

[0011] The above-mentioned buried frame is a rectangular hollow frame composed of a combination of horizontal support rods and vertical support rods. A linear track is arranged on the vertical support rod, and the connecting frame can be slidably installed in the linear track.

[0012] Two pneumatic support rod supports are fixedly installed symmetrically at the bottom of the above-mentioned buried frame. There are two pneumatic support rods. The bottom of the pneumatic support rod is hingedly installed on the corresponding pneumatic support rod support, and the upper end of the travel rod of the pneumatic support rod is hingedly installed on the lower surface of the top platform.

[0013] There are two water tanks, which are symmetrically installed on the upper surface of the top platform. Activated carbon or fiber for purifying water is installed in the water tanks. Normally closed spare water inlets and outlets are provided on the water tanks, which can fill or discharge water into or out of the water tanks.

[0014] A solar panel is installed on the top of the water tank. The solar panel is connected to a battery. The battery is connected to a water pump. The battery is used to supply power to the water pump.

[0015] A pressure sensor for weighing the progress of the buried barrel is arranged on the above-mentioned bottom platform. The pressure sensor is connected to an alarm. When the pressure sensed by the pressure sensor exceeds a threshold value, the alarm sounds.

[0016] A method for using a non-active power lifting underground bucket device comprises the following steps:

[0017] Step a: Pump all the water in the water tank into the water storage tank body through a water pump, so that the weight of the underground bucket moving unit is less than the thrust of the pneumatic support rod, and the pneumatic support rod pushes the underground bucket moving unit to the upper end of the stroke. At this time, the bottom platform is flush with the ground, and the top platform is in the air. Replace the underground bucket on the bottom platform with a new underground bucket, and align the water filter hole of the underground bucket with the water receiving hole of the water storage tank body;

[0018] Step 2: Pump the water from the water storage tank into the water tank through a water pump to make the water tank reach a predetermined water level. During this process, the weight of the underground bucket moving unit gradually exceeds the thrust of the pneumatic support rod, and the underground bucket moving unit moves downward until the bottom platform and the top platform respectively collide with the horizontal support rods at the lower end and the upper end of the underground frame. At this time, the underground bucket moving unit is at the lower end of the stroke, the bottom platform is located in the underground foundation pit, and the top platform is flush with the ground; when the predetermined weight of garbage is put into the underground bucket through the feeding port, the pressure sensor controls the alarm to sound, and returns to step a.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention adopts a pneumatic support rod as a driving component. The elastic force of the pneumatic support rod is fixed, and its load-bearing capacity is higher than the gravity of the buried bucket mobile unit with an empty water tank + a fully loaded buried bucket, and lower than the gravity of the buried bucket mobile unit with a full water tank + an empty buried bucket. Therefore, by injecting and discharging water into the water tank, the buried bucket mobile unit can be adjusted to descend and ascend. In this process, there is no need to use electrical equipment, which solves the problem that the buried bucket device cannot be raised or lowered in a power-off state.

[0021] 2. The device of the present invention is also provided with a water storage tank body, which can collect the sewage in the underground bucket, and then use a water pump to pump the sewage in the underground bucket into the water tank for use as water in the water tank. When the water tank is drained, the water storage tank body can also use the water pump to receive the water in the water tank, thereby realizing the recycling of water tank water and sewage, and effectively saving water resources.

[0022] 3. The present invention provides electric energy for the water pump through the solar panel, which is not affected by the mains power supply, and a spare water inlet and outlet are provided on the water tank. Even if the solar panel or the water pump is damaged, the spare water inlet and outlet are opened to allow water to flow out of the water tank, and the buried barrel mobile unit can be lifted as a whole, which is convenient for equipment maintenance and replacement.

[0023] 4. Since the device of the present invention does not need to be powered by mains electricity, the requirements for the use scenario are greatly reduced. When constructing an underground barrel device in a village or beside a road, there is no need to consider the problem of power supply. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] First embodiment: Figure 1 As shown, the non-active power lifting buried bucket device of the present invention includes a buried foundation pit, a buried frame 2, a pneumatic support rod 1, a bottom platform 4, a buried bucket 5, a connecting frame 6, a top platform 7, a water tank 8, a pedal-type opening and closing cover plate 10, a pneumatic support rod support 12 and other structures.

[0036] The size of the underground foundation pit depends on the number of underground garbage bins. The length, width and height of a large underground foundation pit can reach 12m×2m×2.5m, which can accommodate 5-7 garbage bins. In this embodiment, the underground foundation pit is a rectangular foundation pit with a depth of 2.5m and a length and width of 2 meters. The underground frame 2 is built along the edge of the underground foundation pit. The underground frame 2 is a rectangular hollow frame composed of horizontal support rods and vertical support rods. Diagonal braces for reinforcement are arranged between the horizontal support rods and the vertical support rods. Four straight rails 11 are arranged on the vertical support rods, and the connecting frame 6 can slide up and down in the straight rails 11.

[0037] The pneumatic support rod 1 is connected by a flat head connector, a nitrogen hydraulic cylinder and a travel rod, the travel rod is inserted into the nitrogen hydraulic cylinder, the nitrogen hydraulic cylinder provides hydraulic elasticity for the travel rod, the flat head connector is installed on the pneumatic support rod support 12, and the travel rod is connected to the lower surface of the top platform 7. Two pneumatic support rods 1 can provide 280KG elasticity.

[0038] The bottom platform 4, the underground bucket 5, the connecting frame 6 and the top platform 7 together constitute the underground bucket mobile unit. The bottom platform 4 and the top platform 7 are both arranged horizontally. The underground bucket 5 is placed on the bottom platform 4. The bottom platform 4 is provided with baffles around it to limit the position of the underground bucket 5. The connecting frame 6 is four vertical pillars, connecting the bottom platform 4 and the top platform 7. The area of ​​the top platform 7 is larger than the upper surface of the underground foundation pit. When the underground bucket mobile unit falls to the lower end of the stroke, the four sides of the top platform 7 are against the ground, bearing part of the pressure of the water tank. A feeding port is opened in the middle of the top platform 7, and a pedal-type opening and closing cover 10 is arranged on the feeding port. The user opens the feeding port by stepping on the pedal-type opening and closing cover 10, and then puts the garbage into the underground bucket 5. The water tank 8 is arranged on the top platform 7 on both sides of the pedal-type opening and closing cover 10. Each water tank 8 weighs 140KG after being filled with water. The combined weight of the bottom platform 4, the connecting frame 6, the top platform 7, and the empty water tank is about 120KG, and the buried bin 5 adopts a 240L standard trash bin with a rated full load of 100KG.

[0039] When using the underground bucket lifting device of this embodiment, there are two operations: lifting the underground bucket moving unit and lowering the underground bucket moving unit.

[0040] When raising the underground bucket moving unit, open the water inlet and outlet of the water tank 8, release the water in the water tank 8, so that the weight of the underground bucket moving unit is less than the thrust of the pneumatic support rod 1, and the pneumatic support rod 1 pushes the underground bucket moving unit to the upper end of the stroke. At this time, the bottom platform 4 is flush with the ground, and the top platform 7 is in the air. Replace the underground bucket 5 on the bottom platform 4 with a new underground bucket 5;

[0041] When lowering the underground bucket mobile unit, fill the water tank 8 with water through the water inlet and outlet of the water tank 8. In this process, the weight of the underground bucket mobile unit gradually exceeds the thrust of the pneumatic support rod 1, and the underground bucket mobile unit moves downward until the bottom platform 4 contacts the horizontal support rod at the lower end of the underground frame 2, and the top platform 7 contacts the horizontal support rod at the upper end of the underground frame 2 and the ground. After the underground bucket mobile unit is fixed, the underground bucket lifting device can be used normally. When the underground bucket 5 is full of garbage, the underground bucket mobile unit is raised to replace the underground bucket 5.

[0042] Second embodiment: Figure 2-6 As shown, the present embodiment is different from the first embodiment in that structures such as a water pump 3, a water storage tank 9 and a solar panel 14 are added, the purpose of which is to recycle the water in the water tank and utilize the sewage in the buried barrel 5 at the same time.

[0043] In this embodiment, the buried foundation pit is a rectangular foundation pit with a depth of 3.2m and a length and width of 2m. The extra space at the bottom is used to install a water storage tank 9 and a water pump 3. The water pump 3 is connected to two water tanks 8 through pipelines, and materials for filtering water, such as activated carbon, fiber, etc., are placed in the water tanks 8.

[0044] The buried barrel 5 in this embodiment is also specialized, with a water filter hole at the bottom, a filter screen installed in the water filter hole to prevent oversized debris from entering the water storage tank body 9, and a water receiving hole is provided on the top of the water storage tank body 9, the water filter hole and the water receiving hole are aligned up and down, and the sewage in the buried barrel 5 can enter the water storage tank body 9 after being filtered through the water filter hole.

[0045] The main body of the water pump 3 is placed in the water storage tank 9, and the circuit part is connected to the battery of the solar panel 14. The solar panel 14 is installed on the surface of the pedal-type opening and closing cover 10.

[0046] The water outlet of the water tank 8 is also changed to a normally closed spare water inlet and outlet 13, which is not used at ordinary times. The spare water inlet and outlet 13 is opened only when the equipment is cleaned as a whole to release all the water in the water tank 8. At the same time, the water in the water storage tank body 9 is also pumped into the water tank 8 by the water pump 3, and released through the water tank. Then, the filter material of the water tank 8 is replaced and the water tank 8 and the water storage tank body 9 are cleaned.

[0047] The method of using the lifting buried bucket device of this embodiment is as follows:

[0048] When the underground bucket moving unit is raised, all the water in the water tank 8 is pumped into the water storage tank body 9 by the water pump 3, so that the weight of the underground bucket moving unit is less than the thrust of the pneumatic support rod 1, and the pneumatic support rod 1 pushes the underground bucket moving unit to the upper end of the stroke. At this time, the bottom platform 4 is flush with the ground, and the top platform 7 is in the air. The underground bucket 5 on the bottom platform 4 is replaced with a new underground bucket 5, and the water filter hole of the underground bucket 5 is aligned with the water receiving hole of the water storage tank body 9;

[0049] When lowering the underground bucket moving unit, the water in the water storage tank body 9 is pumped into the water tank 8 through the water pump 3, so that the water tank 8 reaches a predetermined water level. In this process, the weight of the underground bucket moving unit gradually exceeds the thrust of the pneumatic support rod 1, and the underground bucket moving unit moves downward until the bottom platform 4 and the top platform 7 respectively cooperate with the transverse support rods at the lower end and the upper end of the underground frame 2. At this time, the underground bucket moving unit is at the lower end of the stroke, the bottom platform 4 is located in the underground foundation pit, and the top platform 7 is flush with the ground; when the predetermined weight of garbage is put into the underground bucket 5 through the feeding port, the pressure sensor controls the alarm to sound, and the underground bucket moving unit is raised to replace the underground bucket 5.
