Description

Technical Field

[0001] This invention relates to the technical field of rigid landfills, and more particularly to an initial rainwater collection device for rigid landfills for hazardous waste. Background Technology

[0002] All landfill units are divided into unoperated areas, operating areas, and closed areas. Rainwater collected in the unoperated areas enters the plant's rainwater system. The operating areas are covered by mobile awnings. Initial rainwater, being contaminated water, is collected in the initial rainwater pool of the rigid hazardous waste landfill and then sent to the wastewater treatment plant for treatment. After the landfill unit is completed, it is permanently closed according to the operation progress.

[0003] Most existing rainwater collection systems at rigid hazardous waste landfills collect rainwater through connecting pipes. Since only the first 15 minutes of rainwater are collected, manual shut-off valves are required after 15 minutes to stop collection. However, due to the large number of pipes, it takes a long time for workers to shut off the valves one by one, resulting in a large amount of rainwater in the system, increased disposal load, and increased disposal costs. Summary of the Invention

[0004] In view of the problems existing in the initial rainwater collection equipment of the rigid landfill for hazardous waste, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide an initial rainwater collection device for rigid landfills of hazardous waste, the purpose of which is to simultaneously shut down multiple pipes.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including,

[0007] A collection mechanism includes a rigid landfill, a collection section disposed on the rigid landfill, a first sealing section disposed on the collection section, a second sealing section disposed on the collection section, a filter section disposed on the second sealing section, and a cleaning section disposed on the second sealing section;

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1

[0032] Reference Figure 1 , 3 4 and 6 are the first embodiment of the present invention, providing an initial rainwater collection device for a rigid landfill of hazardous waste. This device includes,

[0033] The collection mechanism 100 includes a rigid landfill 101, a collection part 102 disposed on the rigid landfill 101, a first sealing part 103 disposed on the collection part 102, a second sealing part 104 disposed on the collection part 102, a filter part 105 disposed on the second sealing part 104, and a cleaning part 106 disposed on the second sealing part 104.

[0034] The linkage mechanism 200 includes a water storage unit 201 installed on the rigid landfill 101, a conversion unit 202 installed on the water storage unit 201, a linkage unit 203 installed inside the water storage unit 201, and a power unit 204 installed on the rigid landfill 101.

[0035] Preferred, such as Figure 2 As shown, the rigid landfill 101 is made of concrete, and its interior is divided into multiple cavities by concrete slabs. Its top is sealed by a top cover. The collection unit 102 is used to connect the top and bottom of the top cover, thereby collecting rainwater above the top cover into the cavities. The rigid landfill 101 collects rainwater from the first fifteen minutes. In the early stage of rainfall, the rainwater dissolves a large amount of polluting gases such as industrial waste gas, acid gas, and industrial waste gas in the air. After falling to the ground, it washes over roofs, asphalt concrete roads, etc., resulting in a large amount of pollutants in the early rainwater, which will cause a certain degree of pollution to the water environment. Therefore, the early rainwater is collected to meet the requirements of environmental protection.

[0036] During use, rainwater is collected through the collection unit 102. When the collection unit 102 needs to be closed after fifteen minutes, the power unit 204 is activated to drive the linkage unit 203 to rotate, thereby connecting the water storage unit 201 and the conversion unit 202. The rainwater in the water storage unit 201 enters the conversion unit 202. The buoyancy of the rainwater drives the conversion unit 202 to rotate the second sealing part 104. The rotation of the second sealing part 104 causes it to be misaligned with the first sealing part 103, thereby closing the collection unit 102.

[0037] When the filter section 105 needs to be cleaned, rotate the cleaning section 106 to move the filter section 105 out of the collection section 102, thereby maintaining the filter section 105.

[0038] Example 2

[0039] Reference Figures 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the collection unit 102 includes a first collection pipe 102a disposed on the rigid landfill 101, a rotary joint 102b disposed on the first collection pipe 102a, a connecting tube 102c disposed on the rotary joint 102b, a second collection pipe 102d disposed on the rigid landfill 101, and an annular chute plate 102e disposed on the second collection pipe 102d and connected to the connecting tube 102c.

[0040] Preferably, the first collection pipe 102a is used to connect to the lower part of the rigid landfill 101 top cover. The setting of the rotary joint 102b ensures the sealing of the connection between the connecting rotary pipe 102c and the first collection pipe 102a, ensuring the passage of water, and at the same time ensuring that the connecting rotary pipe 102c can rotate. The second collection pipe 102d is used to connect to the upper part of the rigid landfill 101 top cover, thereby collecting rainwater above the rigid landfill 101 top cover. The annular chute plate 102e is used to connect the connecting rotary pipe 102c, ensuring that the connecting rotary pipe 102c can rotate.

[0041] The first sealing part 103 includes a first sealing plate 103a disposed in the second collecting pipe 102d, a first sealing gasket 103b disposed on the first sealing plate 103a, and a first mating hole 103c disposed on the first sealing plate 103a.

[0042] Preferably, the first sealing plate 103a is fixedly disposed inside the second collecting pipe 102d to ensure the stability of the first mating hole 103c, and the first sealing gasket 103b increases the sealing performance when it is in contact with the second sealing plate 104c to prevent rainwater from seeping in.

[0043] The second sealing part 104 includes a bracket 104a disposed in the connecting tube 102c, a sealing connection seat 104b disposed on the bracket 104a, a second sealing plate 104c disposed in the second collecting tube 102d and connected to the sealing connection seat 104b, a second mating hole 104d disposed on the second sealing plate 104c, and a second sealing gasket 104e disposed on the second sealing plate 104c.

[0044] Preferably, bracket 104a is used to install sealing connector 104b, while ensuring that rainwater can pass through. Sealing connector 104b is fixedly connected to second sealing plate 104c, so that when connecting tube 102c rotates, it can drive second sealing plate 104c to rotate, thereby controlling the docking of first docking hole 103c and second docking hole 104d. Sealing connector 104b is provided with sealing gasket to increase the sealing performance of first sealing plate 103a. The number and size of second docking holes 104d are the same as those of first docking holes 103c, and the distance between two adjacent second docking holes 104d is greater than the diameter of second docking holes 104d, ensuring that when second docking holes 104d and first docking holes 103c are misaligned, the first sealing plate 103a and second sealing plate 104c are in a closed state.

[0045] The filter section 105 includes a filter mounting block 105a disposed on the second sealing plate 104c, a filter screen 105b disposed on the filter mounting block 105a, and a cleaning ring 105c disposed on the filter screen 105b.

[0046] Preferably, the filter mounting block 105a is used to install the filter screen 105b and the cleaning threaded sleeve 106a. The filter screen 105b is used to filter impurities and increase the quality of rainwater collection. The cleaning ring 105c is used to clean the inner wall of the second collection pipe 102d.

[0047] The cleaning unit 106 includes a cleaning threaded sleeve 106a disposed on the filter mounting block 105a, a cleaning threaded rod 106b disposed on the cleaning threaded sleeve 106a and connected to the sealing connection seat 104b, a cleaning guide rod 106c disposed on the sealing connection seat 104b, a cleaning handle 106d disposed on the cleaning threaded rod 106b, and an annular groove 106e disposed on the cleaning handle 106d and connected to the cleaning guide rod 106c.

[0048] Preferably, the cleaning threaded rod 106b is rotatably mounted on the sealing connection seat 104b. Since the conversion part 202 limits the connection tube 102c, the rotation of the cleaning threaded rod 106b will not drive the connection tube 102c to rotate. Rotating the cleaning handle 106d drives the cleaning threaded rod 106b to move the filter screen 105b out, thereby facilitating the replacement and maintenance of the filter screen 105b.

[0049] The remaining structure is the same as that in Example 1.

[0050] During use, when the first collection pipe 102a needs to be closed after fifteen minutes, the power unit 204 is activated to drive the linkage unit 203 to rotate, thereby connecting the water storage unit 201 and the conversion unit 202. The rainwater in the water storage unit 201 enters the conversion unit 202. The buoyancy of the rainwater drives the conversion unit 202 to rotate the connecting pipe 102c. The connecting pipe 102c drives the bracket 104a to rotate the sealing connection seat 104b. The sealing connection seat 104b drives the second sealing plate 104c to rotate the second docking hole 104d. The second docking hole 104d rotates and is misaligned with the first docking hole 103c, thereby closing the first collection pipe 102a.

[0051] When the filter screen 105b needs to be cleaned, the cleaning guide rod 106c limits the filter mounting block 105a, so the cleaning threaded sleeve 106a cannot rotate with the cleaning threaded rod 106b. Rotating the cleaning handle 106d drives the cleaning threaded rod 106b to move the cleaning threaded sleeve 106a. The cleaning threaded sleeve 106a drives the filter mounting block 105a to move the second sealing plate 104c along the second collection pipe 102d, thereby moving the filter screen 105b out of the second collection pipe 102d for cleaning and maintenance. At the same time, the filter screen 105b drives the cleaning ring 105c to move and clean the inner surface of the second collection pipe 102d.

[0052] Example 3

[0053] Reference Figure 4 , 6 7 is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the water storage unit 201 includes a water storage tank 201a disposed on the rigid landfill 101, and a water storage pipe 201b disposed on the water storage tank 201a and connected to the second collection pipe 102d.

[0054] Preferably, the water storage tank 201a is located below the second collection pipe 102d, and the water storage pipe 201b is arranged so that while the second collection pipe 102d collects rainwater, it also collects some rainwater into the water storage tank 201a.

[0055] The conversion unit 202 includes a conversion box 202a disposed on the water storage tank 201a, a float plate 202b disposed in the conversion box 202a, a limiting strip 202c disposed in the conversion box 202a, a conversion rack 202d disposed on the float plate 202b, and a conversion gear 202e disposed on the connecting pipe 102c and adapted to the conversion rack 202d.

[0056] Preferably, the bottom of the water storage tank 201a is provided with an arc-shaped cavity to reduce the space occupied by the linkage part 203, thereby reducing the amount of rainwater required for the float 202b to rise, allowing the rainwater to better lift the float 202b. The conversion box 202a has the same shape as the water storage tank 201a, and the volume of the conversion box 202a is smaller than that of the water storage tank 201a, so that even if the water storage tank 201a is not full of rainwater, there is enough water to raise the float 202b to the limit bar 202c. The limit bar 202c is located below the middle of the conversion box 202a.

[0057] The linkage unit 203 includes a first guide rod 203a disposed on the water storage tank 201a, a linkage pipe 203b disposed on the first guide rod 203a, a first connecting hole 203c disposed on the linkage pipe 203b, a second connecting hole 203d disposed on the linkage pipe 203b, a linkage threaded sleeve 203e disposed in the conversion box 202a, a linkage threaded rod 203f disposed on the linkage threaded sleeve 203e and connected to the linkage pipe 203b, a second guide rod 203g disposed on the conversion box 202a and connected to the linkage threaded rod 203f, and a linkage rod 203h disposed between the first guide rod 203a and the second guide rod 203g.

[0058] Preferably, the first guide rod 203a is slidably mounted on the water storage tank 201a, and the water storage tank 201a is provided with a sealing gasket adapted to the first guide rod 203a to increase the sealing performance of the device. The linkage pipe 203b is fixedly connected to the first guide rod 203a and is tubular. The first connecting hole 203c is located on the side away from the conversion box 202a, so that the first connecting hole 203c is always located inside the water storage tank 201a. The second connecting hole 203d is located on the side close to the conversion box 202a, so that the linkage threaded rod 203f can be rotated to drive the device. The second connecting hole 203d enters the conversion box 202a. When both the first connecting hole 203c and the second connecting hole 203d are located in the water storage tank 201a, rainwater cannot enter the conversion box 202a. When the second connecting hole 203d enters the conversion box 202a, the water storage tank 201a and the conversion box 202a are connected through the first connecting hole 203c and the second connecting hole 203d. Due to water pressure, the rainwater in the water storage tank 201a enters the conversion box 202a. The conversion box 202a is equipped with a water outlet for discharging rainwater.

[0059] The power unit 204 includes a power motor 204a mounted on the rigid landfill 101, a splined shaft 204b mounted on the power motor 204a, and a splined bushing 204c mounted on the second guide rod 203g.

[0060] Preferably, the power unit 204 can be replaced with a handle to save on construction costs.

[0061] The remaining structure is the same as that in Example 2.

[0062] During operation, rainwater enters the rigid landfill 101 through the second collection pipe 102d, connecting pipe 102c, and first collection pipe 102a. Simultaneously, rainwater enters the storage tank 201a through the second collection pipe 102d and storage pipe 201b. After rainwater collection is complete, the power motor 204a is started, driving the spline shaft 204b to rotate the spline bushing 204c. The spline bushing 204c drives the second guide rod 203g, causing the linkage threaded rod 203f to rotate and move. The linkage threaded rod 203f drives the linkage pipe 203b, allowing the second connecting hole 203d to enter the conversion box 202a. Due to the first connecting hole 203c, the storage tank 201a and the conversion box 202a are connected, allowing rainwater in the storage tank 201a to enter the conversion box. At the bottom of the conversion box 202a, the buoyancy of the rainwater drives the float 202b to raise the conversion rack 202d. The conversion rack 202d drives the conversion gear 202e to rotate the connecting tube 102c. The connecting tube 102c drives the bracket 104a to rotate the sealing connection seat 104b. The sealing connection seat 104b drives the second sealing plate 104c to rotate the second docking hole 104d. The second docking hole 104d rotates and misaligns with the first docking hole 103c, thereby closing the first collection pipe 102a. Due to the setting of the linkage rod 203h, the power motor 204a can drive multiple linkage pipes 203b to move at the same time, thereby closing multiple water storage tanks 201a at the same time to prevent excessive rainwater collection in the rigid landfill 101.
