Abstract
Description
Technical Field
[0001] This application relates to the field of residual pressure monitoring technology, and in particular to a basement residual pressure sensor installation structure. Background Technology
[0002] The overpressure monitoring system monitors the overpressure value of the basement and adjacent areas in real time through overpressure sensors. It links the overpressure controller and pressure relief valve actuator to dynamically adjust the bypass pressure relief valve of the ventilation duct. By changing the air supply volume in the pressurized area, it controls the pressure difference on both sides of the fire door to ensure that the overpressure of the basement and adjacent areas is effectively controlled in the event of a fire. This not only prevents the spread of smoke but also allows escapees to open the fire door more easily, ensuring the smooth, safe and rapid evacuation of personnel.
[0003] The installation of pipeless residual pressure sensors typically involves first fixing a hardware bracket to a junction box, and then hanging the sensor housing on the hardware bracket using a pre-drilled groove on the back. However, this installation method allows anyone other than professional maintenance personnel to easily remove the sensor, posing a significant risk of theft. Therefore, this application proposes a new technical solution. Utility Model Content
[0004] To improve security, this application provides a basement overpressure sensor mounting structure.
[0005] This application provides a basement overpressure sensor mounting structure, which adopts the following technical solution:
[0006] A basement overpressure sensor installation structure includes a recessed box embedded in the wall, a bracket fixedly connected to the opening of the recessed box, the bracket extending upward from the end opposite to the recessed box, and further includes:
[0007] The assembly block has one side fixedly connected to the back of the sensor housing, and the other side has an assembly groove for the extension end of the bracket to pass through and be hung; wherein, the opening of the assembly groove is larger than the maximum height of the bracket, and the end of the assembly groove extends upward.
[0008] The slide is located on the side wall of the assembly block, below the assembly slot, and connected to the opening of the assembly slot.
[0009] The abutment block slides through the assembly groove and slide rail.
[0010] A limiting component, which is disposed within the assembly block and located on the moving path of the abutment block, is used to limit the abutment block so that the upper end of the abutment block is located on the moving path of the bracket disengaging from the assembly slot.
[0011] The unlocking component, which is issued to the staff, is used to release the limiting component from the abutment block, so that the abutment block can be moved away from the movement path of the bracket detaching from the assembly slot.
[0012] A reset component is used to reset the abutment block, so that the limit component can continue to limit the abutment block.
[0013] Optionally, the side wall of the assembly block is provided with a limiting groove along the transverse direction. The limiting groove is perpendicularly connected to the slide rail. The limiting component includes a limiting plate and a spring. The limiting plate slides through the limiting groove and is located below the abutment block. One end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end is fixedly connected to the end of the limiting plate. The end of the limiting plate away from the spring is connected to the unlocking component. The limiting plate is provided with a drop hole for the abutment block to pass through. When the unlocking component moves the limiting plate so that the end of the limiting plate abuts against the inner wall of the limiting groove, the drop hole aligns with the abutment block, causing the abutment block to move downward.
[0014] Optionally, the unlocking component includes a strong magnetic rod for the worker, and a magnet that is attracted to the strong magnetic rod is embedded in one end of the limiting plate away from the spring. The bottom of the assembly block has a locking channel for the strong magnetic rod to pass through and move. The opening position of the locking channel corresponds to the magnetic end of the limiting plate and is connected to the limiting groove. The opening width of the locking channel is greater than the movement amount of the limiting plate.
[0015] Optionally, the reset assembly includes a pull rope and a fixing block. One end of the pull rope is fixedly connected to the upper end of the abutment block, and the other end of the pull rope is fixedly connected to the fixing block. The side wall of the assembly block has a rope channel for the pull rope to pass through, and the top of the assembly block has a groove for the fixing block to be embedded in. The groove communicates with the rope channel.
[0016] Optionally, the assembly block has a clearance groove along the edge of the groove to facilitate pinching up the fixing block.
[0017] Optionally, the assembly block has multiple protruding structures around the groove.
[0018] In summary, this application includes the following beneficial technical effects: by limiting the abutment block with a limiting component, the abutment block is positioned on the necessary moving path for the bracket to detach from the assembly slot, thereby preventing the bracket from being easily moved out of the assembly slot. The limiting component can only release the abutment block by using an unlocking component, thus increasing the anti-theft capability of the sensor. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0025] This application discloses an installation structure for a basement residual pressure sensor.
[0026] Reference Figure 1 and Figure 2 The basement residual pressure sensor installation structure includes a dark box 1, a bracket 11, an assembly block 2, a slide rail 21, an abutment block 3, a limit component 4, an unlocking component 5, and a reset component 6.
[0027] The junction box 1 is pre-embedded in a groove pre-cut in the wall. The bracket 11 is fixed to the opening of the junction box 1 by means of plates and screws, and the end of the bracket 11 facing away from the junction box 1 extends upward. One side of the assembly block 2 is fixedly connected to the back of the sensor housing. Since the installation structure of this application mainly functions on the assembly block 2, the fixing method can be by adhesive or integral molding to the back of the sensor housing, so that the components inside the sensor housing used for detection and signal processing are not affected during the installation process, thereby separating the assembly block 2 used for installation from the sensor housing.
[0028] Reference Figure 2 and Figure 3On the other side of assembly block 2, there is an assembly groove 22 for the extension end of bracket 11 to pass through and be hung. Since the cross-sectional structure of bracket 11 is L-shaped, the cross-section of assembly groove 22 is also L-shaped, so that assembly block 2 can be hung on bracket 11. It should be noted that in order to enable assembly block 2 to be hung smoothly on bracket 11, the opening height of assembly groove 22 is greater than the maximum height of bracket 11 (vertical section of bracket 11), and the end of assembly groove 22 extends upward. Therefore, when the inner wall of assembly groove 22 of assembly block 2 is hung on bracket 11, the vertical section of bracket 11 extends to the upward-extending end of assembly groove 22, and there will be a space between the horizontal section of bracket 11 and the bottom wall of the opening of assembly groove 22. Therefore, this application seals the space left by setting abutment block 3, so that bracket 11 will not be easily removed from assembly groove 22. The specific setting is as follows:
[0029] The slide 21 is longitudinally opened along the side wall of the assembly block 2 and is located below the assembly groove 22 and communicates with the opening of the assembly groove 22. The abutment block 3 is slidably inserted into the slide 21 and the assembly groove 22. When the assembly groove 22 of the assembly block 2 is hung on the bracket 11, the abutment block 3 is located below the bracket 11. The limiting component 4 is set inside the assembly block 2 and located below the abutment block 3 to prevent the abutment block 3 from moving down, so that the upper end of the abutment block 3 can abut against the lower surface of the bracket 11, so that the extension end of the bracket 11 hooks the end of the assembly groove 22. When the assembly block 2 is moved, the bracket 11 cannot be easily moved out of the assembly groove 22. Instead, the unlocking component 5 needs to release the limiting component 4 from the abutment block 3 so that the abutment block 3 can be moved away from the movement path of the bracket 11 away from the assembly groove 22. Only then can the assembly block 2 be removed from the bracket 11 for easy maintenance.
[0030] After maintenance is completed, the assembly block 2 is reattached to the bracket 11, and the abutment block 3 is reset by the reset component 6, so that the limiting component 4 continues to limit the abutment block 3, so that the abutment block 3 abuts against the lower surface of the bracket 11 again, preventing the bracket 11 from moving out of the assembly slot 22 and increasing the anti-theft performance of the sensor.
[0031] With the above settings, the limiting component 4 limits the abutment block 3, so that the abutment block 3 is located on the necessary moving path of the bracket 11 to detach from the assembly slot 22, thereby preventing the bracket 11 from being easily moved out of the assembly slot 22. The limiting component 4 can only release the limiting component 4 from the abutment block 3 by using the unlocking component 5, thereby increasing the anti-theft capability of the sensor.
[0032] Reference Figure 2 and Figure 3The side wall of the assembly block 2 has a limiting groove 23 opened in the transverse direction. The limiting groove 23 is perpendicularly connected to the slide 21. The limiting component 4 includes a limiting plate 41 and a spring 42. The limiting plate 41 slides in the limiting groove 23 in the transverse direction. The limiting plate 41 is located below the abutting block 3. One end of the spring 42 is fixedly connected to the inner wall of one end of the limiting groove 23. The other end of the spring 42 is fixedly connected to the end of the limiting plate 41. The end of the limiting plate 41 away from the spring 42 is connected to the unlocking component 5.
[0033] When the spring 42 is in its natural state, the upper surface of the limiting plate 41 abuts against the lower end of the abutment block 3, preventing the abutment block 3 from moving downwards. This allows the upper end of the abutment block 3 to extend into the assembly groove 22 and abut against the lower surface of the bracket 11. In order to allow the abutment block 3 to move downwards by moving the limiting plate 41 after the unlocking member 5 is connected to the limiting plate 41, the limiting plate 41 is provided with a drop hole 43 for the abutment block 3 to pass through. The size of the drop hole 43 is larger than the size of the abutment block 3. Thus, when the unlocking member 5 is connected to the limiting plate 41, the spring 42 is deformed by moving the limiting plate 41. When the end of the limiting plate 41 moves to abut against the inner wall of the end of the limiting groove 23, the drop hole 43 aligns with the abutment block 3, allowing the lower end of the abutment block 3 to pass through the drop hole 43 and abut against the bottom of the slide 21. This allows the upper end of the abutment block 3 to move out of the assembly groove 22, enabling the bracket 11 to be removed from the assembly groove 22. It should be noted that a slider (not shown in the figure) is fixed on the side wall of the abutment block 3. The inner wall of the slide 21 is provided with a sliding groove for the slider to slide and connect, so that the abutment block 3 can slide in the vertical direction. Thus, once the abutment block 3 is aligned with the drop hole 43, the lower end of the abutment block 3 can pass smoothly through the drop hole 43.
[0034] The unlocking component 5 includes a strong magnetic rod for the staff. The end of the limiting plate 41 away from the spring 42 is embedded with a magnet that is attracted to the magnetic force of the strong magnetic rod. The bottom of the assembly block 2 is provided with a locking channel 7 for the strong magnetic rod to pass through. The opening position of the locking channel 7 corresponds to the magnetic end of the limiting plate 41, and the upper end of the locking channel 7 is connected to the limiting groove 23, while the lower end is open.
[0035] To ensure that after the operator inserts the strong magnetic rod into the locking channel 7, attracting the end of the strong magnetic rod to the magnetic end of the limiting plate 41, the operator can laterally move the strong magnetic rod to pull the limiting plate 41 away from the spring 42 and abut against the inner wall of the end of the limiting groove 23, aligning the drop hole 43 with the upper abutment block 3, the opening width of the locking channel 7 should be greater than the movement amount of the limiting plate 41. In this embodiment, the movement amount refers to the distance the limiting plate 41 moves when the spring 42 is in its natural state, moving the magnetic end of the limiting plate 41 to abut against the inner wall of the end of the limiting groove 23. It should be noted that the magnetic force between the strong magnetic rod and the magnetic end of the limiting plate 41 is greater than the elastic force of the spring 42, allowing the operator to pull the limiting plate 41 to move using the strong magnetic rod.
[0036] After the limiting plate 41 is moved by the unlocking component 5, allowing the abutment block 3 to pass through the drop hole 43, although the upper end of the abutment block 3 is removed from the assembly slot 22, allowing the bracket 11 to be freely removed from the assembly slot 22, the abutment block 3 needs to continue to abut and limit the bracket 11 in order for the bracket 11 to be reinserted into the assembly slot 22. Therefore, the resetting component 6 needs to pull the abutment block 3 out of the drop hole 43, so that the limiting plate 41 is reset under the action of the spring 42, and the lower end of the abutment block 3 continues to contact the upper surface of the limiting plate 41, thereby resetting the abutment block 3 and allowing the upper end of the abutment block 3 to continue to abut against the bracket 11. The specific structure of the resetting component 6 is as follows:
[0037] Reference Figure 3 and Figure 4 The reset assembly 6 includes a pull rope and a fixing block 61. One end of the pull rope is fixedly connected to the upper end of the abutment block 3, and the other end of the pull rope is fixedly connected to the fixing block 61. The side wall of the assembly block 2 has a rope channel 62 for the pull rope to pass through. In this embodiment, in order to facilitate personnel to pull the abutment block 3 upward to reset, there can be two pull ropes, which are respectively fixed to the two sides of the upper end of the abutment block 3, and the rope channel 62 is correspondingly opened above the two sides of the abutment block 3, so that the pull rope can pass through the rope channel 62. The top of the assembly block 2 has a groove 63 for the fixing block 61 to be embedded. The groove 63 communicates with the rope channel 62, so that the end of the pull rope can first extend out from the rope channel 62 and then be fixed to the fixing block 61, and then the fixing block 61 can be inserted into the groove 63. It should be noted that the length of the pull rope needs to be sufficient for the lower end of the abutment block 3 to abut the lowest end of the slide 21.
[0038] Reference Figure 4 To facilitate the removal of the fixing block 61 from the groove 63 by the staff, the assembly block 2 is provided with a clearance groove 8 at the edge of the groove 63.
[0039] Since the residual pressure sensor is usually installed in a high position indoors, and the fixing block 61 is embedded in the top of the assembly block 2, in order to make it easier for the staff to find the position of the fixing block 61 in time, multiple protruding structures 9 are provided around the groove 63 of the assembly block 2. When the staff touches the protruding structure 9 with their hands, they can know the position of the fixing block 61 in time, which is convenient for operation.
[0040] It should be noted that the bracket 11 is installed at the opening of the dark box 1 by means of a plate. The plate does not completely cover the opening of the dark box 1. The cable inside the dark box 1 can extend to the outside from the bottom of the plate. Secondly, the lower end of the assembly block 2 has a notch, which makes it easy for the cable led out from the dark box 1 to pass through the notch and connect to the terminal block on the sensor housing, so as to facilitate powering the sensor.
[0041] 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.
