Description

Technical Field

[0001] The present invention relates to the field of fences, and particularly to a fence with a damaged alarm function. Background Art

[0002] As an important part of infrastructure, fences are widely used in industrial parks, public facilities, traffic roads and residential areas, playing roles such as safety protection, area division and risk warning. However, traditional fences have significant technical defects in practical applications, mainly reflected in the following two aspects: 1. Lack of damaged alarm function. Existing fences generally adopt passive protection structures, such as metal fences, barbed wire or concrete walls, etc. Their protection status completely depends on the integrity of the physical structure. When the fence is damaged and collapses, managers often cannot obtain alarm information in a timely manner, resulting in safety hazards being difficult to eliminate in a timely manner; 2. Insufficient wind resistance stability. The wind resistance ability of existing fences mainly depends on fixed bases or weighted designs, and their structures lack the ability of adaptive adjustment. In strong wind weather, fences are prone to shaking, tilting or even collapsing due to wind impact. For this reason, this solution proposes a fence with a damaged alarm function. Summary of the Invention

[0003] A fence with a damaged alarm function proposed by the present invention solves the problems that existing fences lack damaged alarm functions and automatic stability maintenance functions.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A fence with a damaged alarm function includes

[0006] A baffle plate. Installation grooves are opened on both the front and back sides of the baffle plate. Gravity sensors are installed on both top sides of the baffle plate, and an alarm component connected to the gravity sensors is installed on one outer wall of the baffle plate. A wind speed sensor is also installed on the top of the baffle plate;

[0007] A protection mechanism. The number of the protection mechanisms is set to two, and the two protection mechanisms are respectively installed in the two installation grooves. The protection mechanism includes a protection plate disposed in the installation groove and a transmission component installed in the installation groove for driving the protection plate to rotate during the up and down movement;

[0008] Sliding grooves are opened on both sides of the installation groove. Rotating shafts are fixed on both top sides of the protection plate. The transmission component includes an adjusting member installed in the sliding groove for driving the rotating shaft to move along the length direction of the sliding groove and a steering member installed in the installation groove for driving the rotating shaft to rotate during the movement;

[0009] The steering member includes an abutting plate fixed on the inner wall of the installation groove and a driving rack movably connected to the side wall of the protection plate through a limiting member. A transmission gear meshing with the driving rack is sleeved on the outer periphery of the rotating shaft. Guide grooves are formed on the outer walls on both sides of the abutting plate, and one end of the driving rack is slidably connected to the guide groove through a guiding member.

[0010] Through the above technical solution, not only can an alarm sound be emitted to remind the staff when the fence is tilted or damaged and collapsed, but also the protection plate can be automatically opened when the wind speed is detected to be too high or the fence is tilted, so as to support the baffle and ensure its stability.

[0011] As a further improvement of the above solution, the guide groove includes an upper inclined section and a lower vertical section, and the inclined section slopes downward toward the side close to the protection plate from top to bottom. The guiding member includes two guiding plates fixed at one end of the driving rack and a guiding column fixed on the outer wall on the opposite side of the two guiding plates. One ends of the two guiding columns respectively extend into the two guide grooves and are slidably connected thereto.

[0012] Through the above technical solution, the driving rack can be driven to move correspondingly when the guiding column slides in the inclined section, while the driving rack will not be driven to move when the guiding column slides in the vertical section.

[0013] As a further improvement of the above solution, the limiting member includes a limiting column fixed on the side wall of the protection plate and a limiting frame movably sleeved on the outer periphery of the limiting column. The top of the limiting frame is fixedly connected to the bottom surface of the driving rack.

[0014] As a further improvement of the above solution, the adjusting member includes a transmission screw rod rotatably connected in the sliding groove and a nut sleeve threadedly sleeved on the outer periphery of the transmission screw rod. One end of the rotating shaft is rotatably connected to the outer periphery of the nut sleeve. An installation cavity is formed at the bottom of the sliding groove, and a transmission motor is installed in the installation cavity, and the output end of the transmission motor is drivingly connected to the bottom of the transmission screw rod.

[0015] As a further improvement of the above solution, a groove is formed on the outer wall of one side of the baffle. The alarm component includes a PLC control panel installed in the groove, an alarm and a storage battery connected to the PLC control panel. The gravity sensor is connected to the PLC control panel. A sealing plate is detachably installed on the outer periphery of the groove through screws, and a plurality of through holes are formed in the sealing plate.

[0016] As a further improvement of the above solution, an anti-climbing mechanism is installed on the top of the baffle. The anti-climbing mechanism includes two side plates fixed on the top surface of the baffle, a top plate arranged between the two side plates, and a pressure sensor installed on the top of the baffle. The pressure sensor is located directly below the top plate. Connecting grooves are formed on one side of the two side plates facing each other. An elastic member connected to the top plate is installed in the connecting groove. The elastic member includes a connecting column fixed in the connecting groove, a buffer spring and a connecting block movably sleeved on the outer periphery of the connecting column. The bottom of the buffer spring is fixedly connected to the bottom of the connecting groove, the top of the buffer spring is fixedly connected to the bottom of the connecting block, and one end of the connecting block is fixedly connected to one end of the top plate.

[0017] Through the above technical solution, the alarm can be activated after the top plate is pressed and lowered, thereby preventing people from climbing over the top of the baffle.

[0018] As a further improvement of the above solution, connectors are installed on the outer walls on both sides of the baffle. The connectors include fixed blocks fixed on the side walls of the baffle and fixing bolts threadedly connected to the fixed blocks. The bottom surface height of the fixed block on one outer wall of the baffle is the same as the top surface height of the fixed block on the other outer wall of the baffle.

[0019] As a further improvement of the above solution, mounting plates are fixed on the bottom surfaces of both the front and back sides of the baffle, and insertion rods are inserted into the mounting plates.

[0020] As a further improvement of the above solution, a plurality of support members are installed on the back surface of the protection plate. The support members include support columns hinged on the back surface of the protection plate and return springs fixed on the support columns. A storage hole for storing the return spring is formed on the back surface of the protection plate, and the other end of the return spring extends into the storage hole and is fixedly connected to its inner wall.

[0021] Through the above technical solution, the support columns can support the protection plate after being unfolded.

[0022] As a further improvement of the above solution, a plurality of notches are formed on the front surface of the installation groove and the front surface of the protection plate.

[0023] Through the above technical solution, the wind resistance of the baffle and the protection plate can be effectively reduced.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. Through the cooperation between the gravity sensor and the alarm component, the alarm can be activated when the baffle is damaged and collapses or tilts, thereby emitting an alarm sound to remind the staff to check.

[0026] 2. Through the settings of the protection mechanism and the wind speed sensor, when the detected external wind speed exceeds the set value, the protection plate will be automatically opened, thereby providing further support for the baffle. At the same time, when the gravity sensor detects that the baffle is tilted, the protection plate will also be automatically opened, so as to use the protection plate to support the baffle, thus preventing it from collapsing and achieving the purpose of automatic stability maintenance.

[0027] 3. The setting of the support member can automatically eject the support column during the unfolding process of the protection plate. When the protection plate contacts the ground, the support column also contacts the ground, thereby playing a role in supporting the protection plate and enabling its surface to withstand greater forces. At the same time, when the protection plate is folded up, it can also be automatically folded by pressing the support column. Brief Description of the Drawings

[0041] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0042] Embodiment 1:

[0043] Please refer to Figures 1-11 , a fence with a damage alarm function in this embodiment includes

[0044] a baffle 1. Connectors are installed on the outer walls on both sides of the baffle 1. The connectors include a fixed block 8 fixed on the side wall of the baffle 1 and a fixed bolt 9 threadedly connected to the fixed block 8. The bottom surface height of the fixed block 8 on one outer wall of the baffle 1 is the same as the top surface height of the fixed block 8 on the other outer wall of the baffle 1. Installation plates 10 are fixed to the bottom surfaces on both the front and back sides of the baffle 1, and insertion rods are inserted into the installation plates 10. When installing the baffle 1, first drive the insertion rods on the installation plates 10 into the ground to fix the baffle 1 to the ground. When connecting two baffles 1, the second fixed blocks 8 on two adjacent baffles 1 can be butted, and then the fixed blocks 8 on the two baffles 1 can be fixed with the fixed bolt 9.

[0045] Both the front and back sides of the baffle 1 are provided with installation grooves 2. Gravity sensors 4 are installed at the top of both sides of the baffle 1. And an alarm component connected to the gravity sensor 4 is installed on one outer wall of the baffle 1. A groove is formed on one outer wall of the baffle 1. The alarm component includes a PLC control panel 30 installed in the groove, an alarm 31 connected to the PLC control panel 30, and a storage battery 32. The gravity sensor 4 is connected to the PLC control panel 30. A sealing plate 29 is detachably installed on the outer periphery of the groove through screws. Multiple through holes are formed in the sealing plate 29. The arrangement of the through holes facilitates the transmission of the alarm sound from the alarm 31. When the baffle 1 is damaged and tilts or collapses, the gravity sensor 4 will sense the change in the gravity direction on the baffle 1, and then transmit it to the PLC control panel 30. The PLC control panel 30 then starts the alarm 31 to emit an alarm sound, thereby reminding the staff, and further achieving the purpose of alarming when damaged.

[0046] There are two protection mechanisms, and the two protection mechanisms are respectively installed in the two installation grooves 2. The bottoms of the two installation grooves 2 are both of an open structure. The protection mechanism includes a protection plate 6 arranged in the installation groove 2 and a transmission component installed in the installation groove 2 for driving the protection plate 6 to rotate during the up and down movement. A wind speed sensor 35 is also installed on the top of the baffle 1. The wind speed sensor 35 is connected to the PLC control panel 30. When the wind speed sensor 35 detects that the external wind speed is too high, it will transmit a signal to the PLC control panel 30. The PLC control panel 30 then starts the transmission component to open the two protection plates 6, thereby supporting the baffle 1 and increasing the wind resistance of the baffle 1.

[0047] Sliding grooves 17 are formed on both sides of the installation groove 2. Rotating shafts 14 are fixed to both sides of the top of the protection plate 6. The transmission component includes an adjusting part installed in the sliding groove 17 for driving the rotating shaft 14 to move along the length direction of the sliding groove 17 and a steering part installed in the installation groove 2 for driving the rotating shaft 14 to rotate during the movement. The adjusting part includes a transmission screw 12 rotatably connected in the sliding groove 17 and a nut sleeve 13 threadedly sleeved on the outer periphery of the transmission screw 12. The outer periphery of the nut sleeve 13 abuts against the inner wall of the sliding groove 17. One end of the rotating shaft 14 is rotatably connected to the outer periphery of the nut sleeve 13. An installation cavity is formed at the bottom of the sliding groove 17. A transmission motor 34 is installed in the installation cavity, and the output end of the transmission motor 34 is drivingly connected to the bottom of the transmission screw 12. When the PLC control panel 30 controls the transmission component to open the protection plate 6, first start the transmission motor 34 to rotate forward, thereby driving the transmission screw 12 to rotate forward. After the transmission screw 12 rotates forward, it drives the nut sleeve 13 to descend, thereby driving the protection plate 6 to descend. On the contrary, when it is necessary to drive the protection plate 6 to rise, it is only necessary to start the transmission motor 34 to rotate in reverse.

[0048] The steering member includes a contact plate 16 fixed to the inner wall of the installation groove 2 and a driving rack 15 movably connected to the side wall of the protection plate 6 through a limiting member. A transmission gear 18 meshing with the driving rack 15 is sleeved on the outer periphery of the rotating shaft 14. Guide grooves 22 are formed on the outer walls on both sides of the contact plate 16. One end of the driving rack 15 is slidably connected to the guide grooves 22 through a guiding member. The guide grooves 22 include an upper inclined section and a lower vertical section, and the inclined section slopes downward toward the side close to the protection plate 6 from top to bottom. The guiding member includes two guide plates 21 fixed to one end of the driving rack 15 and a guide post 23 fixed to the outer walls on the opposite sides of the two guide plates 21. One ends of the two guide posts 23 respectively extend into the two guide grooves 22 and are slidably connected thereto. The limiting member includes a limiting post 19 fixed to the side wall of the protection plate 6 and a limiting frame 20 movably sleeved on the outer periphery of the limiting post 19. The top of the limiting frame 20 is fixedly connected to the bottom surface of the driving rack 15. During the downward movement of the protection plate 6, the driving rack 15 will synchronously descend with the protection plate 2. When the driving rack 15 descends, it will drive the guide post 23 to slide in the guide groove 22. When the protection plate 6 descends, the guide post 23 will gradually slide from the inclined section into the vertical section. And when the guide post 23 gradually slides down in the inclined section, it will drive the driving rack 15 to move away from the contact plate 16, thereby driving the transmission gear 18 to rotate forward, and the rotating shaft 14 will also rotate forward accordingly. Furthermore, it can drive the protection plate 6 to gradually flip outward from the installation groove 2 during the downward movement, achieving the purpose of automatically unfolding the protection plate 6. When the guide post 23 enters the vertical section, as the driving rack 15 continues to move downward, the distance between the driving rack 15 and the contact plate 16 remains unchanged, so the protection plate 6 will no longer continue to open outward during the downward movement until the bottom of the protection plate 6 is flush with the bottom of the baffle 1, and then the motor 34 stops rotating. On the contrary, when folding the protection plate 6, the guide post 23 will enter the inclined section from the vertical section. When the guide post 23 gradually moves upward in the inclined section, it will drive the transmission gear 18 to rotate in reverse, thereby driving the rotating shaft 14 to rotate in reverse. Finally, it can automatically fold the protection plate 6 back into the installation groove 2 during the upward movement of the protection plate 6.

[0049] In this embodiment, a plurality of notches 7 are formed on the front surface of the installation groove 2 and the front surface of the protection plate 6. The arrangement of the notches 7 can be used for air circulation, thereby reducing the wind resistance of the baffle 1 and the protection plate 6.

[0050] Embodiment 2:

[0051] Combined with Figure 1 and Figure 5 - Figure 7, on the basis of Embodiment 1, the further improvement of this embodiment lies in that: an anti-climbing mechanism is installed on the top of the baffle 1. The anti-climbing mechanism includes two side plates 5 fixed on the top surface of the baffle 1, a top plate 3 arranged between the two side plates 5, and a pressure sensor 11 installed on the top of the baffle 1. The pressure sensor 11 is located directly below the top plate 3. Connecting grooves 27 are formed on the opposite sides of the two side plates 5, and elastic members connected to the top plate 3 are installed in the connecting grooves 27. The elastic members include connecting columns 26 fixed in the connecting grooves 27, buffer springs and connecting blocks 25 movably sleeved on the outer periphery of the connecting columns 26. The bottom of the buffer spring is fixedly connected to the bottom of the connecting groove 27, the top of the buffer spring is fixedly connected to the bottom of the connecting block 25, and one end of the connecting block 25 is fixedly connected to one end of the top plate 3. When a person climbs over the baffle 1, after an external object contacts the top plate 3, the top plate 3 will drop accordingly after being pressed. At this time, the buffer spring is compressed. When the top plate 3 contacts the pressure sensor 11, the pressure sensor 11 will transmit a signal to the PLC control panel 30, and the control panel 30 will then activate the alarm 31 to emit an alarm sound, thereby effectively preventing people from climbing over the top of the baffle 1.

[0052] Embodiment 3:

[0053] Combined with Figure 5 and Figure 7 - Figure 10 , on the basis of Embodiments 1 - 2, the further improvement of this embodiment lies in that: a plurality of support members are installed on the back of the protection plate 6. The support members include support columns 24 hinged on the back of the protection plate 6 and return springs 28 fixedly connected to the support columns 24. Receiving holes 33 for receiving the return springs 28 are formed on the back of the protection plate 6. The other end of the return spring 28 extends into the receiving hole 33 and is fixedly connected to its inner wall. When the protection plate 6 is retracted into the installation groove 2, the support column 24 is squeezed by the inner wall of the installation groove 2, and the return spring 28 is also in a compressed state and is received in the receiving hole 33. When the protection plate 6 is gradually unfolded outward, the extrusion of the inner wall of the installation groove 2 on the support column 24 gradually becomes smaller, and the return spring 28 will gradually unfold, thereby driving the support column 24 to spread outwards. Until the protection plate 6 contacts the ground, the support column 24 is also fully unfolded and contacts the ground, thereby playing a further role in supporting the protection plate 6. When the protection plate 6 is retracted into the installation groove 2 again, after the support column 24 abuts against the inner wall of the installation groove 2, the return spring 28 will be continuously compressed during the process of the protection plate 6 gradually rotating into the installation groove 2 until the protection plate 6 is completely retracted into the installation groove 2.

[0054] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
