Description

Technical Field

[0001] The utility model relates to the technical fields of municipal infrastructure construction and Internet of Things technology, and is particularly applicable to an integrated facility that integrates the personnel entrance and ventilation opening of an underground utility tunnel. Background Technique

[0002] With the continuous development of urban infrastructure construction, the underground utility tunnel, as an underground structure that centrally accommodates various pipelines, has received increasing attention in its design and construction.

[0003] As the main access node of the underground utility tunnel, the personnel entrance of the utility tunnel needs to be provided with stairs, fire doors, etc. Generally, a relatively spacious stairwell is set above the ground, thus occupying a large amount of planar and vertical space.

[0004] The ventilation openings of the underground utility tunnel are generally arranged in a double layer. A ventilation fan is arranged at the lower part, and a ventilation pavilion is arranged on the ground. Since the ventilation pavilion needs to have sufficient ventilation area, in order to ensure the ventilation area around the ventilation pavilion, the setting of the ventilation pavilion cannot be too low or the planar area is too small.

[0005] The conventional personnel entrance and ventilation openings of the underground utility tunnel are generally arranged separately, so more land occupation is required. However, there are technical difficulties in designing reasonable personnel entrances and ventilation openings in a narrow space. Traditional design methods often lead to problems such as low space utilization rate, complex structure, and high cost. Especially in the renovation of old streets, it will be very difficult to design the personnel entrance and ventilation openings of the utility tunnel according to the conventional method.

[0034] The present utility model provides an integrated facility that combines a personnel access and a ventilation opening for an underground utility tunnel applicable to narrow spaces, aiming to solve the above problems.

[0035] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in detail in conjunction with specific embodiments and with reference to the accompanying drawings.

[0036] It should be noted in advance that the terms "upper", "lower", "left", "right", "inner", and "outer" in the following embodiments are used to describe the features with reference to the positions of the features in the exemplary embodiments shown in the drawings, and are not intended to limit the protection scope of the present utility model.

[0037] The application scenario of the embodiment of the present utility model is a certain utility tunnel construction project. S Street is a very old street and is located in the low-lying area of the urban drainage. It is necessary to build an underground utility tunnel and an underground drainage culvert to achieve the overall optimization of the street. However, the street is narrow, and there are continuous shops on both sides of the street. Since it is in the low-lying area, the ground is prone to water accumulation when it rains. Therefore, it is very difficult to set the nodes of the underground utility tunnel. Too many nodes, too large a planar area occupied by the nodes, too high a node above the ground, too low a flood prevention height of the node, etc. will all make it impossible to achieve the functions of the underground utility tunnel. Therefore, special settings are required to achieve the node layout.

[0038] Based on the above application scenario, this embodiment provides an integrated facility that combines a personnel access and a ventilation opening for an underground utility tunnel, specifically as Figures 1 to 4 shown.

[0039] Figure 1 and Figure 2 are respectively schematic diagrams of the integrated facility in the embodiment of the present utility model with the upper and lower cover plates in the semi-open state and the open state. For the convenience of seeing the relative position relationships of each part, Figure 1 the upper and lower cover plates in Figure 2 are in the semi-open state. In

[0040] Figure 3 and Figure 4 are respectively Figure 1 schematic diagrams of the integrated facility shown with the upper and lower cover plates in the closed state and the sealed state. For clarity, Figure 3 and Figure 4 omit the stairs leading down to the underground utility tunnel. In Figure 3 the upper and lower cover plates are closed simultaneously and the fan is turned on, and the ventilation pavilion function can be achieved. In Figure 4When the upper cover plate is closed and the lower cover plate covers the ventilation grille, overall enclosure can be achieved to prevent rainwater from entering. Moreover, after the upper cover plate is closed, it can be used as a rest seat for personnel in the landscape area, combined with the relevant shapes of landscape facilities.

[0041] As Figures 1 to 4 shown, the integrated facility of this embodiment includes:

[0042] The personnel entrance 11 and ventilation fan 12 of the underground utility tunnel;

[0043] The housing frame 20 encloses the personnel entrance and ventilation fan into the inner installation space, and at least one side thereof is provided with a ventilation grille, and the upper opening thereof is covered by the upper cover plate 30;

[0044] The multi-purpose lower cover plate 40 is arranged in the installation space, wherein:

[0045] In the first state, the lower cover plate 40 covers the personnel entrance and serves as the door of the personnel entrance;

[0046] In the second state, the lower cover plate 40 covers the ventilation grille to close the ventilation grille.

[0047] The control module is used to control the upper cover plate 30 and the lower cover plate 40 to adapt to different working conditions.

[0048] In this embodiment, the personnel entrance and ventilation opening of the underground utility tunnel are effectively combined, and an integrated facility is adopted to reduce the floor area and realize the equipmentization of complex structures.

[0049] The following details each component of the integrated facility of this embodiment.

[0050] Please refer to Figure 1 and Figure 2 , in this embodiment, the entrance main body 10 of the underground utility tunnel on the ground is a rectangular concrete structure, including: the first section serving as the personnel entrance 11 and the second section for installing the ventilation fan 12. The personnel entrance 11 is connected to the downward entrance stairs 13. The ventilation fan is arranged on the side of the personnel entrance far from the stairs. Among them, the personnel entrance 11 and the ventilation fan 12 are on the same horizontal plane. In other words, the upper surface of the ventilation fan is flush with the door of the personnel entrance formed by the splicing of the first lower cover plate and the second lower cover plate on the horizontal plane.

[0051] Those skilled in the art should understand that the above is only a preferred embodiment of the present utility model, but the present utility model is not limited thereto. In other embodiments of the present utility model, the ventilation fan can also be slightly higher or slightly lower than the personnel entrance, and the positional relationship between the ventilation fan and the personnel entrance can also be adjusted according to needs, and at least part of the present utility model can be realized, and it is also within the protection scope of the present utility model.

[0052] Please refer to Figure 1 and Figure 2 , in this embodiment, the horizontal cross-section of the housing frame 20 is rectangular, and it encloses the entrance main body 10 into its inner installation space; ventilation grilles - front ventilation grille 21 and rear ventilation grille 22 are symmetrically arranged on the front side and the rear side of the housing frame. An upper cover plate 30 is arranged above the frame body frame 20.

[0053] It should be noted that there is an opening above the housing frame 20 here. The upper cover plate 30 is described separately, indicating that the upper cover plate does not belong to the housing frame. In some embodiments of the present utility model, the housing frame is not provided with an upper cover plate, and part of the present utility model can also be realized, and it is also within the protection scope of the present utility model.

[0054] Those skilled in the art should understand that although the horizontal cross-section of the housing frame in this embodiment is designed to be rectangular, the present utility model is not limited thereto. In other embodiments of the present utility model, for practical needs or aesthetic needs, the housing frame can also be designed into other shapes, such as: circular, oval, and its side surface can also be an arc surface, and ventilation grilles can also be provided only on one side surface, or on 4 side surfaces, and the present utility model can be realized, and it is also within the protection scope of the present utility model.

[0055] Please refer to Figure 1 and Figure 2 , ventilation grilles - front ventilation grille 21 and rear ventilation grille 22 are symmetrically arranged on the front side and the rear side of the housing frame. The lower cover plate 40 includes: symmetric left lower cover plate 41 and right lower cover plate 42, and the two are respectively pivotally connected below the corresponding side ventilation grille. The integrated facility in this embodiment further includes: a lower cover plate driving mechanism for driving the left lower cover plate and the right lower cover plate to switch between a first state and a second state.

[0056] Specifically, the lower cover plate driving mechanism includes: two lower hydraulic rods - left lower hydraulic rod 41a and right lower hydraulic rod 42a, and the moving ends of the two are respectively pivotally connected to the left lower cover plate and the right lower cover plate. The two lower hydraulic rods are respectively arranged at a fixed angle with the horizontal plane.

[0057] For the lower left hydraulic rod 41a: When its moving end retracts, the lower left cover plate is disposed on the left side of the personnel entrance and is parallel to the ground; when the moving end extends, it pushes the lower left cover plate to flip upward around the pivot and cover the ventilation grille on the front side, sealing the ventilation grille. The lower right hydraulic rod 42a is similar. The ventilation grilles on both sides are sealed, so that the installation space inside the housing frame is enclosed, preventing rainwater from entering the installation space.

[0058] Furthermore, in order to ensure that rainwater outside does not enter the installation space, elastic sealing gaskets are provided at the peripheral positions of the two lower cover plates corresponding to the ventilation grilles.

[0059] Those skilled in the art should understand that since the lower cover plates are required to seal the ventilation grilles from the inside, the number of lower cover plates is the same as the number of ventilation grilles. In this embodiment, two ventilation grilles are provided - the front ventilation grille 21 and the rear ventilation grille 22. Correspondingly, two lower cover plates are provided - the lower left cover plate 41 and the lower right cover plate 42. However, the present invention is not limited thereto. In other embodiments of the present invention, if there is only one ventilation grille, or more ventilation grilles are provided, setting the same number of lower cover plates can achieve the present invention, and all are within the protection scope of the present invention.

[0060] Those skilled in the art should understand that in this embodiment, hydraulic rods are used to drive the lower cover plates to switch between the first state and the second state. However, the present invention is not limited thereto. In other embodiments of the present invention, other methods can also be used to drive the lower cover plates, such as a motor driving a gear transmission, a belt transmission, etc. As long as the lower cover plates can be switched between the first state and the second state, the present invention can be achieved, and all are within the protection scope of the present invention.

[0061] Please continue to refer to Figures 1 to 4 , the upper cover plate 30 includes: a symmetric upper left cover plate 31 and an upper right cover plate 32, which are respectively pivotally connected to the upper edges of the sides of the housing frame. The upper cover plate driving mechanism includes: two upper hydraulic rods - the upper left hydraulic rod 31a and the upper right hydraulic rod 32b, and the moving ends of the two are respectively pivotally connected to the upper left cover plate 31 and the upper right cover plate 32. The two upper hydraulic rods are respectively disposed at a fixed angle with the horizontal plane.

[0062] Wherein, when the moving ends of the two upper hydraulic rods retract, the second upper cover plate and the second upper cover plate are combined and cover the opening above the housing frame, closing the opening; when the moving ends of the two upper hydraulic rods extend, they push the second upper cover plate and the second upper cover plate to flip upward around the pivot, opening the opening above the housing frame.

[0063] In this embodiment, an upper left cover plate 31 and an upper right cover plate 32 are provided at the upper opening of the housing frame, and both are driven by corresponding hydraulic rods to rotate and open / close. It can be seen that for the housing frame and the upper cover plate, this embodiment adopts a box-type flip design, reducing the space occupied by the integrated facility.

[0064] In order to improve the intelligent level of the integrated facility, in this embodiment, the integrated facility further includes: a water level sensor, which is arranged on the outer side of the housing frame, at the lower side edge of the ventilation grille. Relying on this water level sensor, the rainwater condition outside the housing frame can be judged, ensuring that when the rainwater approaches the lower edge of the ventilation grille, the lower hydraulic rod drives the ventilation grille 21 to rotate and close in time. The control module can automatically control or manually control the opening and closing of both the lower cover plate and the upper cover plate, as well as the opening and closing of the ventilation fan, to meet the functional requirements.

[0065] Figure 5 For Figure 1 The schematic diagram of the sensing / control signal connection of the integrated facility shown. As Figure 5 shown, in this embodiment, the 2 upper hydraulic rods and the 2 lower hydraulic rods are all electrically controlled hydraulic rods. The control module, whose induction signal input end is connected to the water level sensor, whose first control signal output end is connected to the controlled ends of the 2 lower hydraulic rods, whose second control signal output end is connected to the controlled ends of the 2 upper hydraulic rods, and whose third control signal output end is connected to the controlled end of the ventilation fan, realizes the following control logic:

[0066] 1. Control of the lower cover plate

[0067] 1.1 Water level signal → Seal the ventilation grille

[0068] After receiving the water level detection signal sent by the water level sensor, the control module sends a "seal the ventilation grille instruction" to the lower hydraulic rod.

[0069] Please refer to Figure 2 and Figure 4 , after receiving the "seal the ventilation grille" instruction, the two hydraulic rods (41a, 42a) at the lower layer drive the moving ends to extend, thereby pushing the lower cover plate on the corresponding side to flip upward around the pivot axis, covering the ventilation grille on the corresponding side, sealing the ventilation grille on that side, so that the installation space inside the housing frame is closed, preventing rainwater from entering the installation space.

[0070] Preferably, after sealing the ventilation grille, the ventilation fan can be closed simultaneously. At this time, when the control module sends a "seal the ventilation grille" instruction to the lower hydraulic rod, it sends a "close" instruction to the ventilation fan.

[0071] 1.2 No abnormality → Reset the lower cover plate

[0072] After the water level detection signal is not received or the water level detection signal terminates, the control module sends an instruction of "reset" to the lower hydraulic rod.

[0073] Please refer to Figure 3 , after receiving the instruction of "reset", the moving ends of the two lower hydraulic rods (41a, 42a) retract, and the two lower cover plates (41, 42) rotate downward to the horizontal position. After the two lower cover plates (41, 42) are joined together, they seal the personnel entrance. A ventilation space is formed inside the housing frame. The gas discharged from the ventilation fan 12 passes through this space and then is discharged outside the corridor through the ventilation grille. The reverse air intake is the same, realizing normal ventilation.

[0074] Preferably, after the lower cover plate is reset, the ventilation fan can be turned on. At this time, while the control module sends an instruction of "reset" to the lower hydraulic rod, it sends an instruction of "turn on" to the ventilation fan.

[0075] 2. The lower cover plate turns from the ventilation grille to the personnel entrance to realize ventilation

[0076] 2.1 The upper cover plate is opened

[0077] The control module sends an instruction of "open the opening of the housing frame" to the electro-hydraulic rod.

[0078] After receiving the instruction of "open the opening of the housing frame", when the moving ends of the two upper hydraulic rods (31a, 31b) extend, they push the upper left cover plate and the upper right cover plate to turn upward around the pivot axis, opening the opening above the housing frame. After the opening above the housing frame is opened, the ventilation fan 12 can be repaired. Then, the lower cover plate is opened, and personnel can enter the utility tunnel through the personnel entrance and go down the stairs.

[0079] 2.2 The upper cover plate is reset

[0080] The control module sends an instruction of "close the opening of the housing frame" to the lower hydraulic rod.

[0081] After receiving the instruction of "close the opening of the housing frame", the moving ends of the two upper hydraulic rods (31a, 31b) retract, thereby pulling back the upper cover plates on the corresponding sides. The upper left cover plate and the upper right cover plate cover the opening above the housing frame, and the two are joined together and interlocked to ensure overall sealing, so that rainwater will not leak from the top. And after the two upper cover plates are closed, the overall plane is larger than the opening above the housing frame, ensuring that rainwater falls from the periphery and will not leak into the installation space inside.

[0082] Furthermore, after the upper cover plate is reset, the upper cover plate can be used as a rest seat for personnel in the landscape area, and is integrally arranged in combination with the relevant shapes of the landscape facilities, improving the artistry of the municipal design.

[0083] 3. Other control methods

[0084] In the above description, an implementation method of automatically controlling the upper cover plate and the lower cover plate by using a water level sensor is proposed. However, the present utility model is not limited thereto. In other embodiments of the present utility model, one or more of the following implementation methods can also be adopted simultaneously.

[0085] 3.1 Remote control

[0086] In this embodiment, the control module includes: a remote control unit. After receiving a remote control signal through the remote control unit, the control module sends a "close ventilation grille instruction" to the lower hydraulic rod.

[0087] 3.2 Manual control

[0088] The control module includes: a manual control unit. After receiving a manual control signal through the manual control unit, the control module sends an instruction of "close ventilation grille" to the lower hydraulic rod.

[0089] 3.3 Hand control

[0090] In special cases, without using the control module, the upper cover plate and / or the lower cover plate can be directly opened and closed manually.

[0091] Through the above control in this embodiment, the following functions can be achieved:

[0092] ① When the upper and lower cover plates are opened simultaneously, the function of a personnel entrance can be achieved.

[0093] ② When the upper and lower cover plates are closed simultaneously and the fan is turned on, the function of a ventilation pavilion can be achieved.

[0094] ③ When the upper cover plate is closed and the lower cover plate covers the ventilation grille, overall enclosure can be achieved to prevent rainwater from entering.

[0095] ④ After the upper cover plate is reset, it can be used as a rest seat for personnel in the landscape area. Combined with the relevant shapes of the landscape facilities, the unity of functionality and artistry can be achieved.

[0096] It can be seen that this embodiment is applicable to an integrated facility structure that combines a personnel entrance and a ventilation opening in a small space. It has a simple structure, occupies a small area, has little influence on the vertical space, effectively combines the ventilation opening and the personnel entrance, and can close the ventilation grille through automatic control to prevent rainwater backflow. At the same time, it occupies a small area, does not protrude too much above the ground, and the upper space can be comprehensively utilized.
