Description

Technical Field

[0001] This invention relates to the field of municipal construction technology, and more specifically, to a safety protection device for municipal engineering and its installation method. Background Technology

[0002] In my country, municipal facilities refer to various buildings, structures, and equipment installed within the planned construction area of ​​urban areas and towns, providing paid or free public goods and services to residents based on government responsibility and obligations. The construction of various public infrastructure supporting urban life falls under the category of municipal engineering. Examples include common urban roads, bridges, subways, and various pipelines closely related to daily life: rainwater, sewage, water supply, greywater, electricity, telecommunications, heating, gas, etc. The construction of squares and urban green spaces also falls under the category of municipal engineering. Safety protection, or security, means the absence of danger, harm, and accidents. Protection means preparedness and vigilance. Preparedness refers to taking precautions to deal with attacks or avoid harm, while vigilance refers to both prevention and protection. In summary, safety protection is about making preparations and protecting against attacks or avoiding harm, thereby ensuring that the protected object is in a safe state free from danger, harm, and accidents.

[0003] Traditional municipal engineering safety protection devices simply involve placing protective panels, mainly relying on increasing the weight of the panels. However, the overall integrity between the panels is not strong, and they are prone to gaps under collisions or other external forces, reducing the protective effect and posing certain safety hazards. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a municipal engineering safety protection device that is highly integrated, capable of improving the connection strength between various guardrail bodies and enhancing protective strength, thus achieving a more robust and regulated effect. Furthermore, the invention incorporates a testing component, which improves the control over the connection strength between the guardrail bodies under different external forces, thereby increasing the safety factor.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a municipal engineering safety protection device, comprising a plurality of guardrail units for forming a fixed protection range and a connector for connecting two adjacent guardrail units. The guardrail unit includes a guard plate body, adjusting buckles disposed on the radial side walls of the guard plate body, and a drive unit disposed within the guard plate body for moving the adjusting buckles left and right and releasing or tightening the guard plate body. The adjusting buckles on the radial side walls of the guard plate body are staggered.

[0006] The present invention is further configured such that: the connector includes a detection rod that passes through each adjustment buckle after the adjustment buckles of two adjacent protective plate bodies are stacked, a fixing block respectively disposed at both ends of the detection rod, and a slot disposed on the detection rod, the slot being configured to limit and fix the adjustment buckle when the adjustment buckle moves left and right.

[0007] The present invention is further configured such that: the driving unit includes a connecting plate for connecting each adjusting buckle, an active cavity disposed in the body of the guard plate and for the movement of the connecting plate, a hydraulic cavity disposed in the body of the guard plate, a piston plate disposed in the hydraulic cavity and connected to the connecting plate via a connecting rod, and a reset unit disposed on the rodless cavity side of the hydraulic cavity.

[0008] The present invention is further configured such that the driving units are symmetrically arranged on both sides of each protective plate body.

[0009] The present invention is further configured such that: a fixing structure for fixing or releasing the adjusting buckle is provided between the connecting plate and the adjusting buckle, the fixing structure including a plurality of placement slots provided on the connecting plate for placing each adjusting buckle, a through hole provided on the connecting plate and penetrating each placement slot, a locking plate penetrating in the through hole, an opening provided on the locking plate for opening or closing the placement slot, and a push-pull device for driving the locking plate to move axially back and forth and opening or closing the placement slot.

[0010] An installation method for the aforementioned safety protection device in municipal engineering further includes a pressure detector mounted on a detection rod, used to adjust the tightening or loosening force of the adjusting buckle according to the pressure value detected by the detection rod; a drive device connected to the rod chamber of the hydraulic chamber, used to apply or release pressure to the rod chamber of the hydraulic chamber; and a controller, used to be electrically connected to the pressure detector and drive the drive device to adjust the tightness according to the detected pressure value. The controller includes a monitoring module, used to set the optimal pressure value after assembly to P, set the maximum pressure value on the detection rod after the guard plate body is displaced during the tension stage to P0, and receive the electrical signal from the pressure detector; a comparison module, used to compare the pressure value detected by the pressure detector with the set optimal pressure value, and then adjust the state of the drive device; a timing module, used to control the pressure application time of the drive device and set the longest pressure application control time to S; and a drive module, used to control the start and stop of the drive device. The specific installation steps are as follows: S1, according to the fixed protection range to be enclosed, place each guardrail along the boundary of the area to be enclosed in sequence, and stack the adjusting buckles of adjacent guardrail bodies.

[0011] S2. The detection rod is connected to each adjusting buckle, the detection rod passes through each adjusting buckle, and fixing blocks are fixed at both ends of the detection rod;

[0012] S3. Real-time monitoring of the pressure value of the detection rod after installation, driven by the controller and the drive device, and the pulling force of the detection rod is applied through the adjusting buckles on both sides of the detection rod, so that the pressure value monitored by the detection rod is P;

[0013] S4. Adjust the pressure values ​​detected by the two adjacent detection rods to the P value to complete the assembly.

[0014] The present invention is further configured to include a collision barrier test section, the specific operation steps of which are as follows: S50, after each protective plate body is installed, the pressure value of the pressure detector on the detection rod between two adjacent protective plate bodies is monitored in real time, and the monitoring value is Pt.

[0015] S51. During the first time period, if there are uncertain factors in the protected area, the pressure value of the pressure detector on the detection rod between two adjacent protective plate bodies is monitored in real time, and the monitored pressure value is P1.

[0016] S52. Determine the relationship between P1 and P value. If P1 is less than or equal to P value, then within this time period, it is determined that the two adjacent protective bodies are either loose or have not moved. In this case, fine-tuning can be performed using the drive device.

[0017] S53. If P1 is greater than P, then there is an external force involved in the adjacent protective body, and the drive module drives the drive device, thereby driving the adjustment buckle to form a pulling force on the detection rod to counteract the external force.

[0018] S54. In step S53, the driving time of the driving device is detected by the timing unit. The detection time is S1. If the driving time S1 is greater than S, then in the second time period, the driving devices in all the protective bodies are driven and driven towards the side opposite to the force-bearing protective body. The pressure value of the pressure detector on the detection rod between the two adjacent protective bodies is monitored in real time. The monitoring value is P2. The difference between P2 and P0 is determined. The pressure value of the pressure detector on the detection rod is controlled within the P0 value by driving the driving device.

[0019] S55. Determine the difference between P2 and P0. If P2 is less than P0, continue monitoring the pressure value of the pressure detector on the detection rod during this time period.

[0020] S56. If P2 is greater than P0, it is necessary to control the current of the electromagnet to open it. After the electromagnet is turned on, the lock plate is attracted by the energized electromagnet, thereby opening the placement slot on the connecting plate. The adjusting buckle is no longer under force, and the adjacent guard plate body is opened.

[0021] S57. During the third time period, the pressure value of the pressure detector on the detection rod between the two adjacent guard plate bodies is monitored in real time. The monitored pressure value is P3. If P3 is greater than P0, it is necessary to control the current of the electromagnet to open it. After the electromagnet is opened, the lock plate is attracted by the energized electromagnet, thereby opening the placement slot on the connecting plate. The adjusting buckle is no longer under force, and the adjacent guard plate body is opened instantly.

[0022] By adopting the above technical solution, the following beneficial effects are achieved: 1. In this invention, the municipal engineering safety protection device is configured to include several guardrail units for forming a fixed protection range and a connector for connecting two adjacent guardrail units. By cooperating with the connector, the guardrail units are connected to form a stable structure. Furthermore, by configuring the guardrail unit to include a guard plate body, adjusting buckles set on the radial side walls of the guard plate body, and a drive unit set in the guard plate body for moving the adjusting buckles left and right and releasing or tightening the guard plate body, the adjusting buckles on the radial side walls of the guard plate body are staggered. In order to improve the stability after the guardrail units are connected, the drive unit can be used to adjust the connection between two adjacent guard plate bodies, thereby improving the overall integrity, practicality, and simple structure.

[0023] 2. In this invention, the connector is configured to include a detection rod that passes through each adjustment buckle after the adjustment buckles of two adjacent guard plate bodies are stacked, a fixing block that is respectively set at both ends of the detection rod, and a slot set on the detection rod. The slot is configured to limit and fix the adjustment buckle when the adjustment buckle moves left and right. Because the detection rod can strengthen the structure of the two adjacent guard plate bodies by cooperating with the pressure detector, and the fixing block set on the detection rod can fix the detection rod, and the slot can improve the limit and fixation of the adjustment buckle after pressure adjustment, thus improving stability.

[0024] 3. To facilitate installation and facilitate quick disconnection of adjacent guard plate bodies in specific environments, a fixing structure for fixing or releasing the adjusting buckles is provided between the connecting plate and the adjusting buckle. This improves the effectiveness of releasing or fixing the adjusting buckles. The fixing structure includes several placement slots on the connecting plate for placing each adjusting buckle, through holes on the connecting plate that pass through each placement slot, a locking plate that passes through the through holes, an opening on the locking plate for opening or closing the placement slots, and a push-pull device for driving the locking plate to move axially and open or close the placement slots. With the above structure, since the placement slots are for placing the adjusting buckles and the connecting plate also has through holes that pass through each placement slot, the locking plate fixes each adjusting buckle. The adjusting buckle can be removed from the opening of the locking plate by pulling the locking plate with the push-pull device. The structure is simple and has strong stability.

[0025] 4. In the installation method of the present invention, by setting a pressure detector and a controller, the pressure value of the detection rod is detected in real time during the installation process, which improves the fixing effect of each guard plate body and greatly enhances the stability. Moreover, the installation method of the present invention also includes a collision barrier test section, which forms different adjustment modes for different external forces, ensuring that under different external forces, the driving unit forms different action modes on the adjustment buckle. The test effect is good, the structure is simple, and the practicality is strong. Attached Figure Description

[0033] Reference Figures 1 to 6 The present invention provides a further description of an embodiment of a municipal engineering safety protection device and its installation method.

[0034] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0035] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0036] A municipal engineering safety protection device includes a plurality of guardrail units 1 for forming a fixed protection range and a connector 2 for connecting two adjacent guardrail units 1. Each guardrail unit 1 includes a guardrail body 10, adjusting buckles 11 disposed on both radial side walls of the guardrail body 10, and a drive unit disposed within the guardrail body 10 for moving the adjusting buckles 11 left and right and releasing or tightening the guardrail body 10. The adjusting buckles 11 on the radial side walls of the guardrail body 10 are staggered. In this invention, the municipal engineering safety protection device is configured to include a plurality of guardrail units 1 for forming a fixed protection range and a connector for connecting two adjacent guardrail units 1. 2. By using the connector 2 with the guardrail unit 1, stability is achieved after connecting each guardrail unit 1. Furthermore, by configuring the guardrail unit 1 as including the guard plate body 10, the adjusting buckles 11 disposed on the radial side walls of the guard plate body 10, and the drive unit disposed within the guard plate body 10 for moving the adjusting buckles 11 left and right and releasing or tightening the guard plate body 10, the adjusting buckles 11 on the radial side walls of the guard plate body 10 are staggered. In order to improve the stability after connecting each guardrail unit 1, the connection strength between two adjacent guard plate bodies 10 can be improved by adjusting them through the drive unit, thereby improving the overall integrity, practicality, and simple structure.

[0037] The present invention is further configured such that the connector 2 includes a detection rod 20 passing through each adjustment buckle 11 after the adjustment buckles 11 of two adjacent guard plate bodies 10 are stacked, a fixing block 21 respectively disposed at both ends of the detection rod 20, and a slot 22 disposed on the detection rod 20. The slot 22 is configured to limit and fix the adjustment buckles 11 when they move left and right. In the present invention, by configuring the connector 2 to include a detection rod 20 passing through each adjustment buckle 11 after the adjustment buckles 11 of two adjacent guard plate bodies 10 are stacked, a fixing block 21 respectively disposed at both ends of the detection rod 20, and a slot 22 disposed on the detection rod 20, the slot 22 is configured to limit and fix the adjustment buckles 11 when they move left and right. Because the detection rod 20 can strengthen the structure of the two adjacent guard plate bodies 10 by cooperating with the pressure detector 23, and the fixing block 21 disposed on the detection rod 20 can fix the detection rod 20, and the slot 22 disposed on the detection rod can improve the limiting and fixing of the adjustment buckles 11 after pressure adjustment, the stability is improved.

[0038] The present invention is further configured such that the drive unit includes a connecting plate 30 for connecting each adjusting buckle 11, a movable cavity 31 disposed within the guard plate body 10 for the movement of the connecting plate 30, a hydraulic cavity 32 disposed within the guard plate body 10, a piston plate 33 disposed within the hydraulic cavity 32 and connected to the connecting plate 30 via a connecting rod, and a reset unit 34 disposed on the rodless cavity side of the hydraulic cavity 32. With the above-described structure, the drive unit uses the hydraulic cavity 32 as the main drive chamber, and the movable cavity 31 is used for the movement of the connecting plate 30. When the drive cylinder applies pressure to the hydraulic cavity 32, pressure is generated on the connecting plate 30, which in turn applies pressure to the detection rod 20, achieving the effect of subsequent adjustment or testing.

[0039] The present invention is further configured such that the driving units are symmetrically arranged on both sides of each protective plate body 10. By adopting the above-described structure for the driving units, the distribution of the driving units can achieve the effect of bidirectional adjustment of the protective plate body 10. It is highly practical, simple in structure, and can also increase the pulling force on the protective plate body 10 by applying pressure on one side, thereby forming a good protective adjustment effect and greatly improving its practicality.

[0040] The present invention is further configured such that a fixing structure for fixing or releasing the adjusting buckle 11 is provided between the connecting plate 30 and the adjusting buckle 11. This fixing structure includes a plurality of placement slots 40 disposed on the connecting plate 30 for placing each adjusting buckle 11, a through hole 41 disposed on the connecting plate 30 and penetrating each placement slot 40, a locking plate 42 penetrating within the through hole 41, an opening 43 disposed on the locking plate 42 for opening or closing the placement slots 40, and a push-pull device 44 for driving the locking plate 42 to move axially back and forth and open or close the placement slots 40. To facilitate installation and to allow for quick disconnection of adjacent guard plate bodies 10 under specific conditions, the fixing structure between the connecting plate 30 and the adjusting buckle 11 improves the stability of the adjusting buckle 11. The effect of releasing or fixing 1 is achieved by setting the fixing structure as follows: a plurality of placement slots 40 set on the connecting plate 30 for placing each adjusting buckle 11, a through hole 41 set on the connecting plate 30 and passing through each placement slot 40, a locking plate 42 passing through the through hole 41, an opening 43 set on the locking plate 42 for opening or closing the placement slots 40, and a push-pull device 44 for driving the locking plate 42 to move axially and reciprocate to open or close the placement slots 40. With the above structure, since the placement slots 40 are used to place the adjusting buckles 11, and the connecting plate 30 is also provided with through holes 41 passing through each placement slot 40, the locking plate 42 forms a fixation of each adjusting buckle 11, and the adjusting buckle 11 can be taken out from the opening 43 of the locking plate 42 by pulling the locking plate 42 through the push-pull device 44. The structure is simple and has strong stability.

[0041] An installation method for the aforementioned safety protection device in municipal engineering further includes a pressure detector 23 mounted on the detection rod 20, used to adjust the tightening or loosening force of the adjusting buckle 11 according to the pressure value detected by the detection rod 20; a drive device communicating with the rod chamber of the hydraulic chamber 32, used to apply or release pressure to the rod chamber of the hydraulic chamber 32; and a controller 6, used to be electrically connected to the pressure detector 23 and to drive the drive device to adjust the tightness according to the detected pressure value. The controller 6 includes a monitoring module used to set the optimal pressure value P after assembly and to set the tension stage to cause the protective plate to... After the body 10 is displaced, the maximum pressure value on the detection rod 20 is P0, and the electrical signal from the pressure detector 23 is received; the comparison module is used to compare the pressure value detected by the pressure detector 23 with the set optimal pressure value, and then adjust the state of the drive device; the timing module controls the duration of the pressure applied by the drive device, and sets the longest pressure control time to S; the drive module is used to control the start and stop of the drive device; the specific installation steps are as follows: S1, according to the fixed protection range to be enclosed, place each guardrail along the boundary of the area to be enclosed in sequence, and stack the adjustment buckles 11 of the adjacent guardrail bodies;

[0042] S2. By connecting the detection rod 20 to each adjusting buckle 11, the detection rod 20 passes through each adjusting buckle 11, and fixing blocks 21 are fixed at both ends of the detection rod 20;

[0043] S3. Real-time monitoring of the pressure value of the detection rod 20 after installation, driven by the controller 6 to drive the drive device, and the adjustment buckles 11 on both sides of the detection rod 20 to exert a pulling force on the detection rod 20, so that the pressure value monitored by the detection rod 20 is P;

[0044] S4. Adjust the pressure values ​​detected by the two adjacent detection rods 20 to the P value to complete the assembly.

[0045] The present invention is further configured to include a collision barrier test section, the specific operation steps of which are as follows: S50, after each guard plate body 10 is installed, the pressure value of the pressure detector 23 on the detection rod 20 between two adjacent guard plate bodies 10 is monitored in real time, and the monitoring value is Pt.

[0046] S51. During the first time period, if there are uncertain factors in the protected area, the pressure value of the pressure detector 23 on the detection rod 20 between two adjacent protective plate bodies 10 is monitored in real time, and the monitored pressure value is P1.

[0047] S52. Determine the relationship between P1 and P value. If P1 is less than or equal to P value, then within this time period, it is determined that the two adjacent protective bodies are either loose or have not moved. In this case, fine-tuning can be performed using the drive device.

[0048] S53. If P1 is greater than P, then there is an external force involved in the adjacent protective body, and the drive module drives the drive device, thereby driving the adjustment buckle 11 to form a pulling force on the detection rod 20 to counteract the external force.

[0049] S54. In step S53, the driving time of the driving device is detected by the timing unit. The detection time is S1. If the driving time S1 is greater than S, then in the second time period, the driving devices in all the protective bodies are driven and driven towards the side opposite to the force-bearing protective body. The pressure value of the pressure detector 23 on the detection rod 20 between the two adjacent protective plate bodies 10 is monitored in real time. The monitored value is P2. The size between P2 and P0 is determined. The pressure value of the pressure detector 23 on the detection rod 20 is controlled within the P0 value by driving the driving device.

[0050] S55. Determine the difference between the values ​​of P2 and P0. If P2 is less than the value of P0, continue to monitor the pressure value of the pressure detector 23 of the detection rod 20 during this time period.

[0051] S56. If P2 is greater than P0, it is necessary to control the current of the electromagnet to open the electromagnet. After the electromagnet is opened, the locking plate 42 is attracted by the energized electromagnet, thereby opening the placement slot 40 on the connecting plate 30. The adjusting buckle 11 is no longer under force, and the adjacent guard plate body 10 is opened.

[0052] S57. During the third time period, the pressure value of the pressure detector 23 on the detection rod 20 between the two adjacent guard plate bodies 10 is monitored in real time. The monitored pressure value is P3. If P3 is greater than P0, the current of the electromagnet needs to be controlled to open and close. After the electromagnet is opened, the locking plate 42 is attracted by the energized electromagnet, thereby opening the placement slot 40 on the connecting plate 30. The adjusting buckle 11 is no longer under force, and the adjacent guard plate body 10 is opened instantly.

[0053] In the installation method of the present invention, by setting up a pressure detector 23 and a controller 6, the pressure value of the detection rod 20 is detected in real time during the installation process, which improves the fixing effect of each guard plate body 10 and greatly enhances the stability. Moreover, the installation method of the present invention also includes a collision barrier test section, which forms different adjustment modes for different external forces, ensuring that under different external forces, the driving unit forms different action modes on the adjustment buckle 11. The test effect is good, the structure is simple, and the practicality is strong.

[0054] In this embodiment of the invention, by incorporating a collision-blocking test during installation, different adjustment methods can be formed according to different pressures, such as fine-tuning of the protective body; driving the adjustment buckle 11 to generate a pulling force on the detection rod 20 to counteract the external force; driving all the driving devices in the protective body and driving them towards the side opposite to the protective body subjected to force; and controlling the current on and off of the electromagnet, after the electromagnet is connected to the current, the locking plate 42 is attracted by the energized electromagnet, thereby opening the placement slot 40 on the connecting plate 30, the adjustment buckle 11 is no longer under force, and the adjacent protective plate body 10 is opened instantly. These are all different forms of measures taken according to the different forces generated during a collision, thereby more accurately simulating the collision-blocking situation, increasing the practical effect, and improving stability.

[0055] The aforementioned driving device in all protective bodies drives the protective body to the side opposite to the protective body being subjected to force. This is achieved by using the driving device to pull all the protective body 10 in the opposite direction to the protective body being subjected to force, thus creating an extreme force.

[0056] In this embodiment of the invention, the driving device can be used to make the adjusting buckle exert a pulling force on the detection rod 20 through the driving device, thereby locking each guard plate body 10 and adding two adjacent guard plate bodies 10 to lock them. This can replace the driving device in all the protective bodies and drive it towards the side away from the protective body being subjected to force, which is also another driving method.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.

Adjust the pressure values ​​detected by the two adjacent detection rods (20) to the P value to complete the assembly.

5. The installation method of the municipal engineering safety protection device according to claim 4, characterized in that, It also includes a collision barrier test section. The push-pull device (44) is composed of an electromagnet and a permanent magnet set on the lock plate (42). The specific operation steps are as follows: S50. After installing each guard plate body (10), the pressure value of the pressure detector (23) on the detection rod (20) between two adjacent guard plate bodies (10) is monitored in real time. The monitoring value is Pt. S51. During the first time period, if there are uncertain factors in the protected area, the pressure value of the pressure detector (23) on the detection rod (20) between two adjacent protective plate bodies (10) is monitored in real time, and the monitored pressure value is P1. S52. Determine the size between P1 and P value. If P1 is less than or equal to P value, then within this time period, it is determined that the two adjacent guard plate bodies (10) are either loose or have not moved. At this time, fine adjustment can be made by driving the oil cylinder. S53. If P1 is greater than P, then there is an external force in the adjacent guard plate body (10), and the drive module drives the drive cylinder, thereby driving the adjustment buckle (11) to form a pulling force on the detection rod (20) to counteract the external force. S54. In step S53, the driving time of the driving cylinder is detected by the timing unit. The detection time is S1. If the driving time S1 is greater than S, then in the second time period, the driving cylinders in all the guard plate bodies (10) are driven and driven towards the side opposite to the force-bearing guard plate body (10). The pressure value of the pressure detector (23) on the detection rod (20) between two adjacent guard plate bodies (10) is monitored in real time. The monitoring value is P2. The size between P2 and P0 is determined. The pressure value of the pressure detector (23) on the detection rod (20) is controlled within the P0 value by driving the driving cylinder. S55. Determine the difference between the values ​​of P2 and P0. If P2 is less than the value of P0, continue to monitor the pressure value of the pressure detector (23) of the detection rod (20) during this time period. S56. If P2 is greater than P0, it is necessary to control the current of the electromagnet to open the electromagnet. After the electromagnet is opened, the lock plate (42) is attracted by the energized electromagnet, thereby opening the latch on the connecting plate (30). The adjusting latch (11) is no longer under force and the adjusting latch (11) has no force constraint. The adjacent guard plate body (10) is then opened. S57. During the third time period, the pressure value of the pressure detector (23) on the detection rod (20) between the two adjacent guard plate bodies (10) is monitored in real time. The monitored pressure value is P3. If P3 is greater than P0, it is necessary to control the current of the electromagnet. After the electromagnet is connected to the current, the lock plate (42) is attracted by the energized electromagnet, thereby opening the placement slot (40) on the connecting plate (30). The adjusting buckle (11) is no longer under force, and the adjacent guard plate body (10) is opened instantly.
