Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a hydraulic floor door for wastewater maintenance based on a dual hydraulic cylinder. Background Technology

[0002] In modern cities, a complex network of domestic wastewater is collected through extensive underground sewage channels and transported to wastewater recycling stations for unified disinfection and sterilization, thus achieving the recycling and reuse of domestic wastewater. Rainwater storage tanks are rainwater collection facilities that primarily retain peak rainwater runoff within the tank, allowing it to gradually drain after the maximum flow rate decreases. This achieves the goals of mitigating rainwater peaks, improving rainwater utilization, controlling initial rainwater pollution of receiving water bodies, and playing a positive role in drainage scheduling between drainage areas.

[0003] Currently, most common water storage tanks are equipped with manhole covers to cover the tank body. These manhole covers are usually fixed and installed by pre-burying them in the road surface with asphalt. Since the manhole covers are quite heavy, during maintenance and inspection, workers usually need to use special tools to pry them open. This maintenance method is inefficient and time-consuming and labor-intensive for construction workers. Utility Model Content

[0004] To facilitate the maintenance of sewage storage tanks, this application provides a hydraulic floor door for sewage maintenance based on dual hydraulic cylinders.

[0005] The hydraulic floor door for sewage maintenance based on dual hydraulic cylinders provided in this application adopts the following technical solution: A hydraulic floor door for sewage maintenance based on dual hydraulic cylinders includes a regulating tank body, a rotating cover, and a supporting cylinder. The regulating tank body has two water storage tanks. The top surface of the regulating tank body is connected to two supporting frames, which are arranged one-to-one with the two water storage tanks. The rotating cover is rotatably mounted on each of the supporting frames. The supporting cylinder is disposed in the water storage tank. The cylinder body of the supporting cylinder is rotatably connected to the vertical side wall of the water storage tank. The supporting cylinder is disposed on the vertical side wall of the water storage tank near the rotating side of the rotating cover. The output shaft of the supporting cylinder extends obliquely upward and is rotatably connected to the bottom surface of the rotating cover.

[0006] By adopting the above technical solution, when the rotating cover needs to be opened, the output shaft of the support cylinder extends and drives the rotating cover to open, avoiding the need for operators to use tools to pry up the manhole cover, thus improving maintenance efficiency and reducing the labor intensity of workers. Through the cooperation of the regulating tank body, the rotating cover, and the support cylinder, the automatic opening and closing of the rotating cover is achieved, which facilitates the maintenance of the regulating tank.

[0007] Optionally, a ladder is provided on the vertical inner wall of the water storage tank, and a control switch is provided on the inner wall of the water storage tank. The control switch is electrically connected to the support cylinder.

[0008] By adopting the above technical solution, the ladder facilitates the operator's access to the bottom of the water tank, and the control switch controls the state of the support cylinder from the inside, improving the safety of the maintenance process and reducing the possibility of the operator being trapped in the water tank.

[0009] Optionally, multiple support cylinders are provided in each of the water storage tanks, and the output shafts of the support cylinders are arranged in a non-parallel manner.

[0010] By adopting the above technical solution, since the output shafts of several supporting cylinders are not parallel, the stability is improved through synchronous coordination and compensation between the two hydraulic cylinders when the rotating cover is raised and in a horizontal state. The arrangement of several supporting cylinders enhances the load-bearing capacity of the rotating cover.

[0011] Optionally, a support base is provided on the vertical inner wall of the water storage tank, the cylinder body of the support cylinder is rotatably connected to the support base, and a support plate is vertically provided on the bottom surface of the support base to abut against the inner wall of the water storage tank.

[0012] By adopting the above technical solution, the setting of the support plate on the support base improves the connection stability between the support cylinder and the water storage tank.

[0013] Optionally, an auxiliary support assembly is provided on the bottom surface of the rotating cover. The auxiliary support assembly includes a rotating sleeve rod and a sliding rod. One end of the rotating sleeve rod is rotatably connected to the bottom surface of the rotating cover, and one end of the sliding rod is slidably disposed in the rotating sleeve rod.

[0014] By adopting the above technical solution, in order to share the pressure on the support cylinder, extend the service life of the support cylinder, and improve the stability of the support cylinder during support, the sliding rod is stretched to a suitable position when the support cylinder lifts the rotating cover, and its end is placed on a suitable position on the support frame, thereby achieving auxiliary support for the rotating cover.

[0015] Optionally, the support frame is provided with a placement groove for placing the end of the slide rod.

[0016] By adopting the above technical solution, the extended end of the slide bar is placed in the placement slot of the support frame during support, which improves the stability of the auxiliary support component during support.

[0017] Optionally, the auxiliary support assembly further includes a pull rod, an adjusting rack, and a limiting block. The adjusting rack is disposed on one side of the slide rod along the length direction of the slide rod. The pull rod passes through the rotating sleeve rod and is slidably connected to it. One end of the pull rod located inside the rotating sleeve rod is connected to the limiting block. One side of the limiting block is provided with limiting teeth corresponding to the limiting rack. The width of the adjusting rack is smaller than the width of the slide rod, and the width of the limiting block is the same as the width of the adjusting rack.

[0018] By adopting the above technical solution, when adjusting the position of the slide rod, the pull rod is pulled until the limiting block separates from the adjusting rack. After the slide rod is adjusted to the appropriate position, the pull rod is pushed until the limiting teeth of the limiting block engage with the adjusting rack, thereby locking the position of the slide rod.

[0019] Optionally, a positioning pin is slidably disposed on the bottom surface of the rotating cover, and a positioning blind hole is provided on the outer wall of the rotating sleeve rod. When the rotating sleeve rod rotates to fit against the rotating cover, the positioning blind hole corresponds to the end of the positioning pin.

[0020] By adopting the above technical solution, when the auxiliary support components are not required, the rotating sleeve can be folded up and the positioning pin can be inserted into the positioning blind hole, thereby achieving the positioning of the rotating sleeve.

[0021] Optionally, a first guardrail is connected to the bottom surface of the rotating cover. The first guardrail is parallel to the vertical sidewall of one end of the water storage tank along its length. The first guardrail is located at one end of the bottom surface of the rotating cover along its length. When the rotating cover is fully extended, the first guardrail is in a horizontal state. A second guardrail is rotatably mounted on the inner wall of the water storage tank away from the rotation axis of the rotating cover. The second guardrail includes a vertically mounted first connecting frame and a second connecting frame. The first connecting frame is rotatably connected to the vertical inner wall of the water storage tank. The second connecting frame is vertically mounted at one end of the first connecting frame along its length, close to the first guardrail. A traction rope is connected between the second connecting frame and the bottom surface of the rotating cover. When the rotating cover is fully extended, the first connecting frame rotates to a vertical state, and one end of the second connecting frame is connected to one end of the first guardrail.

[0022] By adopting the above technical solution, when the rotating cover is closed, the first guardrail and the second guardrail are stored in the water storage tank. When the rotating cover is opened, the first and second guardrails rotate to the edge of the top surface of the water storage tank, and one end of the first guardrail connects with one end of the second connecting frame, thus protecting the water storage tank and improving the safety of the water storage tank.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the storage tank body, the rotating cover and the supporting cylinder, the automatic opening and closing of the rotating cover is realized, which facilitates the maintenance of the storage tank. 2. The auxiliary support components share the pressure on the support cylinder during support, extending the service life of the support cylinder and improving the stability of the support cylinder during support. 3. The control switch internally controls the state of the support cylinder, improving the safety of the maintenance process and reducing the possibility of operators being trapped in the water tank.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be further described in detail below. An embodiment of this application provides a hydraulic floor door for sewage maintenance based on a dual hydraulic cylinder, which facilitates the maintenance of regulating tanks.

[0031] Example 1 Reference Figure 1 A hydraulic floor door for sewage maintenance based on a dual hydraulic cylinder includes a regulating tank body 1, a rotating cover 2, and a supporting cylinder 3. Two water storage tanks 101 are formed at the top of the regulating tank body 1, and two supporting frames 15 are connected to the top of the regulating tank body 1, with each supporting frame 15 corresponding to one of the two water storage tanks 101. A ladder 4 is vertically installed on the vertical inner wall of each water storage tank 101, and a control switch 5 is installed on the vertical inner wall of each water storage tank 101, electrically connected to the supporting cylinder 3.

[0032] Reference Figure 1 and Figure 2 Several support seats 6 are provided on the vertical inner wall of the water storage tank 101. A support plate 7 is vertically mounted on the bottom surface of each support seat 6, with one side of the support plate 7 fitting against the vertical inner wall of the water storage tank 101. The support seats 6 are located on the vertical inner wall of the water storage tank 101 near the side where the rotating cover 2 connects to the support frame 15. One support cylinder 3 is provided on each support seat 6. The support seat 6 is rotatably connected to the cylinder body of the support cylinder 3, and the output shaft of the support cylinder 3 is rotatably connected to the bottom surface of the rotating cover 2. Several auxiliary cylinders 22 are rotatably connected to the side of the water storage tank 101 where the support seats 6 are located. The output shafts of the auxiliary cylinders 22 are rotatably connected to the bottom surface of the rotating cover 2. The vertical plane containing the output shafts of the auxiliary cylinders 22 is parallel to the vertical plane containing the output shafts of the support cylinders 3, but the straight line containing the output shafts of the auxiliary cylinders 22 is not parallel to the straight line containing the output shafts of the support cylinders 3.

[0033] Reference Figure 1 A first guardrail 16 is connected to the bottom surface of one end of the rotating cover 2 along its length. The first guardrail 16 is parallel to the inner wall of the water storage tank 101 along its length, and the length of the first guardrail 16 is less than the width of the water storage tank 101. A second guardrail 17 is rotatably connected to the vertical inner wall of the water storage tank 101 away from the rotation axis of the rotating cover 2. The second guardrail 17 includes a first connecting frame 171 and a second connecting frame 172. One end of the first connecting frame 171 along its length is perpendicularly connected to one end of the second connecting frame 172. A rotating plate 18 is connected to one end of the first connecting frame 171 along its width. The rotating plate 18 is rotatably connected to the vertical inner wall of the water storage tank 101. The second connecting frame 172 is located at the end of the first connecting frame 171 near the first guardrail 16. The second connecting frame 172 is rotatably connected to the side wall of the water storage tank 101 along its length. The vertical plane of the first guardrail 16 and the vertical plane of the second guardrail 17 are staggered.

[0034] Reference Figure 1Two first connecting ears 19 are connected to the side of the second connecting frame 172 away from the first connecting frame 171. Two second connecting ears 20 are provided on the bottom surface of the rotating cover 2. The two first connecting ears 19 and the two second connecting ears 20 are arranged in a one-to-one correspondence. A traction rope 21 is connected between the first connecting ears 19 and the corresponding first connecting ears 19. When the rotating cover 2 is fully opened, the first connecting frame 171 rotates to a vertical position, and the second connecting frame 172 rotates until one end of it corresponds to one end of the first guardrail frame 16.

[0035] The implementation principle of the hydraulic floor door for sewage maintenance based on dual hydraulic cylinders in Embodiment 1 of this application is as follows: When maintenance is required inside the water storage tank, the support cylinder 3 is activated, the output shaft of the support cylinder 3 extends and lifts the rotating cover 2, realizing the automatic opening and closing of the rotating cover 2, which helps to improve the maintenance efficiency of the water storage tank. The setting of the control switch 5 allows the operator to control the opening and closing of the rotating cover 2 from the inside, reducing the possibility of the operator being locked in the water storage tank. The setting of several support cylinders 3 improves the support stability of the rotating cover 2. Since the output shafts of the support cylinders 3 and the auxiliary cylinders 22 are not axially parallel, when driving the rotating cover 2 to rotate, the several support cylinders 3 and the several auxiliary cylinders 22 coordinate with each other, improving the support stability of the rotating cover 2.

[0036] When the rotating cover 2 is unfolded, the first guardrail 16 unfolds to a horizontal position, and the traction rope 21 on the rotating cover 2 pulls the second guardrail 17, causing it to rotate. When the rotating cover 2 is fully unfolded, the first guardrail 16, the first connecting frame 171, and the second connecting frame 172 rotate to a vertical position, with one end of the first guardrail 16 corresponding to one end of the second connecting frame 172. The first guardrail 16 and the second guardrail 17 provide protection for the edge of the water storage tank 101 when the rotating cover 2 is unfolded, thus improving the safety of the water storage tank. When the rotating cover 2 is closed, both the first guardrail 16 and the second guardrail 17 are retracted into the water storage tank 101, without interfering with the ground structure.

[0037] The rotating cover 2 is molded from 304 patterned stainless steel sheet and uses a hydraulic system to open and close it, ensuring stable and noiseless operation. The support cylinder 3 and auxiliary cylinder 22 used in this application are gas spring balance cylinders to reduce the load on the rotating cover 2 during opening and closing. The opening and closing process of the rotating cover 2 supports local and remote APP operation via PLC control system, as well as safety sensing functions. In the event of a power outage, personnel in the underground storage tank can manually operate the emergency hydraulic station to open the rotating cover 2, enabling escape.

[0038] Example 2 Reference Figure 3 and Figure 4The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 further includes an auxiliary support assembly 8. The auxiliary support assembly 8 includes a rotating sleeve 81, a sliding rod 82, a limiting waist-shaped block 83, an adjusting rack 84, a limiting block 85, a pull rod 86, a pull block 87, and a return spring 88. The auxiliary support assembly 8 is disposed on the bottom surface of the rotating cover 2. One end of the rotating sleeve 81 is rotatably connected to the bottom surface of the rotating cover 2, and one end of the sliding rod 82 is slidably disposed within the rotating sleeve 81. A limiting waist-shaped hole 821 is provided along the length direction of the sliding rod 82. The limiting waist-shaped block 83 is connected to the limiting sleeve and slidably disposed within the limiting waist-shaped hole 821. The adjusting rack 84 is disposed along the length direction of the sliding rod 82, and the width of the adjusting rack 84 is smaller than the width of the sliding rod 82. A pull rod 86 passes through one side of the rotating sleeve rod 81 and is slidably connected to it. One end of the pull rod 86 located in the limiting sleeve rod is connected to a limiting block 85. The width of the limiting block 85 is the same as the width of the adjusting rack 84. A limiting tooth 851 is provided on the side of the limiting block 85 near the adjusting rack 84. The other end of the pull rod 86 located outside the rotating sleeve rod 81 is connected to a pull block 87. A return spring 88 is sleeved on the pull rod 86. One end of the return spring 88 is connected to the limiting block 85, and the other end is connected to the inner wall of the rotating sleeve rod 81. In its natural state, the limiting tooth 851 of the limiting block 85 is engaged with the adjusting rack 84 under the action of the return spring 88.

[0039] Reference Figure 3-5 A connecting plate 9 is connected to the bottom surface of the rotating cover 2. A connecting rod 10 is slidably mounted on the connecting plate 9. One end of the connecting rod 10 is connected to a connecting block 11, and the other end is connected to a positioning pin 12. A positioning blind hole 13 is provided on the rotating sleeve 81. When the rotating sleeve 81 rotates to fit against the rotating cover 2, the positioning blind hole 13 is positioned corresponding to the end of the positioning pin 12. A placement groove 14 for accommodating the sliding rod 82 is provided on the top surface of the support frame 15.

[0040] The implementation principle of a hydraulic floor door for sewage maintenance based on a dual hydraulic cylinder in Embodiment 2 of this application is as follows: When the rotating cover 2 is opened, the rotating sleeve 81 is opened and the pull block 87 is pulled outward. The limiting block 85 is separated from the adjusting rack 84 under the action of the pull rod 86. The slide rod 82 is pulled to a suitable length, the pull block 87 is released, and the limiting block 85 is reset under the action of the return spring 88. The limiting teeth 851 re-engage with the adjusting rack 84, thereby locking the position of the slide rod 82. The end of the slide rod 82 rests in the placement groove 14, which provides stable support for the rotating cover 2, helps to share the force of the supporting cylinder 3, and also increases the stability of the rotating cover 2.

[0041] When the auxiliary support assembly 8 is not required, the positioning pin 12 is inserted into the positioning blind hole 13 on the rotating sleeve 81 to limit the position of the rotating sleeve 81.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
