[0001] The utility model relates to the technical field of safety monitoring, in particular to a safety monitoring device for construction projects. Background Technique

[0002] During the construction process of construction projects, safety is the life of construction projects. The safety production situation in the construction project market of our country is severe, and the incidence rate of production safety accidents remains high, which has brought serious impacts and economic losses to construction units and contractors. With the continuous development of technology, in order to facilitate the construction of construction projects, we can collect, analyze and guide construction information through visual management throughout the life cycle of the building.

The top of the front side of the left side of the monitoring camera body is fixedly connected to a placement mechanism. The top of the front surface of the monitoring camera body is fixedly connected to a stabilizing mechanism.

[0007] Preferably, the placement mechanism includes a base block. The bottom of the right side of the base block is fixedly connected to the top of the front side of the left side of the monitoring camera body. The top of the base block is movably connected to a support rod through a pin. The front side of the bottom of the support rod is fixedly connected to a spring. The other end of the spring is fixedly connected to the bottom of the front surface of the base block.

[0008] Preferably, the stabilizing mechanism includes a limiting ring. The bottom of the back surface of the limiting ring is fixedly connected to the top of the front surface of the monitoring camera body. A convex groove is formed on the front surface of the limiting ring. A convex block is slidably connected to the inner wall of the convex groove. The front surface of the convex block is fixedly connected to the right side of the back surface of the main body rod.

[0009] Preferably, a spring pot is arranged on the front side of the left side of the top of the monitoring camera body. The front surface of the spring pot is fixedly connected to a nozzle.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The utility model solves the problem that in a construction site, there is generally too much floating dust, and dust is likely to be adsorbed on the lens of the monitoring camera body. When too much dust accumulates, it will directly block the light, affecting the permeability and detail performance of the picture, resulting in a blurred picture and a discounted monitoring effect. By setting a motor and a fiber cloth, when a large amount of dust adheres to the lens of the monitoring camera body and needs to be cleaned, the user starts the motor. The output end of the motor drives the main rod to rotate, and the main rod rotates together with the fiber cloth to wipe the lens of the monitoring camera body, achieving the effect of assisting monitoring.

[0015] 2. The utility model solves the problem that when the motor drives the main rod to rotate one week and then stops, the main rod rotates and presses down on the support rod, causing the support rod to rotate. At the same time, the spring is deformed by the extrusion of the support rod and the base block to generate a resilience force. When the main rod completely passes through the support rod, the resilience force of the spring restores the spring and pushes the support rod to reset. Thus, when the main rod rotates one week and the motor stops, the main rod is supported and limited by the support rod to prevent the main rod from falling vertically due to the inability of the motor to support and fix the main rod when it stops, thereby blocking the monitoring view of the monitoring camera body.

[0016] 3. The utility model solves the problem that when the motor drives the main body to rotate and the fiber cloth wipes the lens of the monitoring camera body, the main rod rotates. At the same time, the convex block moves along the convex groove track on the limit ring to stably assist the rotation track of the main rod, preventing the output end from having a certain jitter when driving the main rod to rotate, which causes the rotation track of the main rod to deviate, so that the fiber cloth cannot completely fit the lens of the monitoring camera body for wiping, thereby improving the stability of the main rod during rotation.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 5 shown, a safety monitoring device for construction engineering provided by the present invention includes a monitoring camera body 1 and a support plate 2. The back of the monitoring camera body 1 is fixedly connected to the front of the support plate 2. The front side of the top of the monitoring camera body 1 is fixedly connected to a motor 3. The output end of the motor 3 is fixedly connected to a main body rod 4. A fiber cloth 5 is arranged on the back of the main body rod 4. The top of the front side of the left side of the monitoring camera body 1 is fixedly connected to a placing mechanism 6. The top of the front of the monitoring camera body is fixedly connected to a stabilizing mechanism 7.

[0025] Referring to Figure 2 and Figure 3 , the placing mechanism 6 includes a base block 601. The bottom of the right side of the base block 601 is fixedly connected to the top of the front side of the left side of the monitoring camera body 1. The top of the base block 601 is movably connected to a support rod 602 through a pin. The front side of the bottom of the support rod 602 is fixedly connected to a spring 603. The other end of the spring 603 is fixedly connected to the bottom of the front of the base block 601.

[0026] As a technical optimization solution of the present utility model, by setting the placement mechanism 6, when the motor 3 drives the main body rod 4 to rotate one week and then stops, the main body rod 4 rotates and presses down on the support rod 602, causing the support rod 602 to rotate. At the same time, the spring 603 is deformed by the extrusion of the support rod 602 and the base block 601 to generate a resilience force, so that when the main body rod 4 completely passes through the support rod 602, the resilience force of the spring 603 restores the spring 603 and pushes the support rod 602 to reset. Thus, when the main body rod 4 rotates one week and the motor 3 stops, the main body rod 4 is supported and limited by the support rod 602 to prevent the main body rod 4 from falling vertically due to the inability to limit and fix the main body rod 4 when the motor 3 stops, thereby blocking the monitoring view of the monitoring camera body 1.

[0027] Reference Figure 1 and Figure 4 As shown in FIGS. 7 and 8, the stabilizing mechanism 7 includes a limiting ring 701. The bottom of the back surface of the limiting ring 701 is fixedly connected to the top of the front surface of the monitoring camera body 1. A convex groove 702 is formed on the front surface of the limiting ring 701. A convex block 703 is slidably connected to the inner wall of the convex groove 702. The front surface of the convex block 703 is fixedly connected to the right side of the back surface of the main body rod 4.

[0028] As a technical optimization solution of the present utility model, by setting the stabilizing mechanism 7, when the motor 3 drives the main body to rotate and the fiber cloth 5 wipes the lens of the monitoring camera body 1, the main body rod 4 rotates. At the same time, the convex block 703 moves along the trajectory of the convex groove 702 on the limiting ring 701 to stably assist the rotation trajectory of the main body rod 4, preventing the output end of the motor 3 from having a certain jitter when driving the main body rod 4 to rotate, resulting in an offset of the rotation trajectory of the main body rod 4, so that the fiber cloth 5 cannot completely fit the lens of the monitoring camera body 1 for wiping, thereby improving the stability of the main body rod 4 during rotation.

[0029] Reference Figure 1 As shown in FIGS. 15 and 16, a spring pot 8 is provided on the front side of the left side of the top of the monitoring camera body 1. A nozzle 9 is fixedly connected to the front surface of the spring pot 8. The nozzle 9 is communicated with the spring pot 8. An electric telescopic rod 10 is fixedly connected to the rear side of the left side of the top of the monitoring camera body 1. The output end of the electric telescopic rod 10 is movably connected to the back surface of the spring pot 8. A cleaning liquid is provided inside the spring pot 8.

[0030] As a technical optimization solution of the present utility model, by setting a spring pot 8, a nozzle 9 and an electric telescopic rod 10, before the fiber cloth 5 wipes the lens of the monitoring camera body 1 by rotating the main body rod 4, the user first starts the electric telescopic rod 10. The piston end of the electric telescopic rod 10 pushes the spring pot 8, causing the spring pot 8 to be squeezed and folded, and at the same time generating a resilience force, so that the cleaning liquid in the spring pot 8 is sprayed onto the fiber cloth 5 through the nozzle 9. Then the fiber cloth 5 is wetted. After that, by using the resilience force of the spring pot 8, when the piston end of the electric telescopic rod 10 returns to its original position, the resilience force resets the spring pot 8. During this process, the spring pot 8 will inhale air for filling, so that the electric telescopic rod 10 can squeeze the spring pot 8 repeatedly for many times, spraying the cleaning liquid in portions, so that the fiber cloth 5 can be wetted by the cleaning liquid before each wipe of the lens of the monitoring camera body 1, thereby improving the wiping effect of the fiber cloth 5 on the lens of the monitoring camera body 1.

[0031] Reference Figure 1 , on the left side of the front surface of the support plate 2, a time relay 11 is fixedly connected, and on the top of the left side of the front surface of the support plate 2, a control box 12 is fixedly connected. The electric telescopic rod 10 and the motor 3 are both electrically connected to the control box 12 through wires, and the time relay 11 is electrically connected to the control box 12 through a wire.

[0032] As a technical optimization solution of the present utility model, by setting a time relay 11 and a control box 12, after the monitoring camera body 1 is installed at a high place for monitoring, when the lens of the monitoring camera body 1 needs to be automatically cleaned regularly, the user sets two sets of values for the time relay 11 in advance. When the first set of values ends counting, the time relay 11 sends a signal indicating the end of the first set of values to the control box 12, and at the same time the second set of values starts counting. Subsequently, the control box 12 first sends a start signal to the electric telescopic rod 10. The piston end of the electric telescopic rod 10 pushes the spring pot 8, causing the spring pot 8 to be squeezed and folded, so that the cleaning liquid in the spring pot 8 is sprayed onto the fiber cloth 5 through the nozzle 9. Then the fiber cloth 5 is wetted. Then, the control box 12 sends a signal to the motor 3, and the output end of the motor 3 drives the main body rod 4 to rotate, so that the fiber cloth 5 rotates one week to wipe the lens of the monitoring camera body 1. When the wiping is completed, the second set of values of the time relay 11 ends counting. Subsequently, the control box 12 receives the signal and sends a reset signal to the electric telescopic rod 10. Then, the first set of values of the time relay 11 re-enters the countdown state, so that the lens of the monitoring camera body 1 can be automatically cleaned by the fiber cloth 5 regularly.

[0033] Reference Figure 2 , on the front side of the bottom of the spring pot 8, a first magic tape 13 is fixedly connected, and on the front side of the top left of the monitoring camera body 1, a second magic tape 14 is fixedly connected. The bottom of the first magic tape 13 is adhered to the top of the second magic tape 14.

[0034] As a technical optimization solution of the present utility model, by providing the first magic tape 13 and the second magic tape, when the spring kettle 8 is placed on the monitoring camera body, the first magic tape 13 and the second magic tape 14 are quickly adhered, so that the spring kettle 8 is quickly fixed on the monitoring camera body 1. At the same time, due to the effect that the first magic tape 13 and the second magic tape can be adhered repeatedly, when the cleaning liquid in the spring kettle 8 needs to be replenished, it can be quickly removed from the monitoring camera body 1 for replenishment, thereby improving the replenishment speed of the cleaning liquid in the spring kettle 8 by the user.

[0035] Reference Figure 4 and Figure 5 and, at the bottom of the inner wall of the nozzle 9, a silica gel cross valve 15 is fixedly connected, and the front surface of the fiber cloth 5 is fixedly connected to the back surface of the main body rod 4 through a double-sided tape 16.

[0036] As a technical optimization solution of the present utility model, by providing the silica gel cross valve 15 and the double-sided tape 16, when the spring kettle 8 is filled with the cleaning liquid and fixed to the monitoring camera body 1 through the first magic tape 13 and the second magic tape 14, the cleaning liquid is blocked by the silica gel cross valve 15. When the spring kettle 8 is squeezed, under the action of pressure, the cross cut of the silica gel cross valve 15 opens, thereby allowing the fluid to pass through. Once the pressure decreases or reverses, the valve will automatically close to cut off the backflow of the fluid and ensure that the fluid only flows in one direction, thereby preventing the cleaning liquid from flowing out naturally. Due to the fact that the fiber cloth 5 is fixed to the main body rod 4 through the double-sided tape 16, when the fiber cloth 5 is excessively worn after long-term repeated use, the user can tear the fiber cloth 5 off the main body rod 4, then replace it with a new fiber cloth 5, and then fix it to the main body rod 4 through the double-sided tape 16, thereby improving the cleaning efficiency at the lens of the monitoring camera body 1.

[0037] Working principle and usage process of the utility model: When in use, after the monitoring camera body 1 is installed at a high place for monitoring, in order to avoid dust in the construction site from adhering and accumulating at the lens of the monitoring camera body 1 and affecting the monitoring effect, the user sets two sets of values for the time relay 11 in advance. When the first set of values finishes timing, the time relay 11 sends a signal indicating the end of the first set of values to the control box 12, and at the same time, the second set of values starts timing. Subsequently, the control box 12 first sends a start signal to the electric telescopic rod 10. The piston end of the electric telescopic rod 10 pushes the spring kettle 8, causing the spring kettle 8 to be squeezed and folded, so that the cleaning liquid in the spring kettle 8 is sprayed onto the fiber cloth 5 through the nozzle 9. Then the fiber cloth 5 is wetted. Then, the control box 12 sends a signal to the motor 3. The output end of the motor 3 drives the main body rod 4 to rotate. Subsequently, the main body rod 4 rotates, and at the same time, the convex block 703 moves along the convex groove 702 of the limit ring 701, stably assisting the rotation trajectory of the main body rod 4 and pressing down the support rod 602, causing the support rod 602 to rotate. At this time, the spring 603 deforms under the extrusion of the support rod 602 and the base block 601 to generate a resilience force. Thus, when the main body rod 4 completely passes through the support rod 602, the resilience force of the spring 603 restores the spring 603 and pushes the support rod 602 to reset. Therefore, after the fiber cloth 5 rotates one week and wipes the lens of the monitoring camera body 1, when the motor 3 stops, the main body rod 4 is supported and limited by the support rod 602 and fixed. Thus, the wiping work is completed. At the same time, the second set of values of the time relay 11 finishes timing. Subsequently, the control box 12 receives the signal and sends a reset signal to the electric telescopic rod 10. Then the spring kettle 8 is restored, and the first set of values of the time relay 11 re-enters the countdown state. Thus, the lens of the monitoring camera body 1 can be automatically cleaned by the fiber cloth 5 regularly, thus having the advantage of auxiliary monitoring.

[0038] To sum up: For this safety monitoring device for construction projects, by setting the motor 3 and the fiber cloth 5, when a large amount of dust adheres to the lens of the monitoring camera body 1 and needs to be cleaned, the user starts the motor 3. The output end of the motor 3 drives the main body rod 4 to rotate, and the main body rod 4 rotates together with the fiber cloth 5 to wipe the lens of the monitoring camera body 1, solving the problem that there is generally too much dust in the construction site, and the lens of the monitoring camera body is prone to adsorbing dust. When too much dust accumulates, it will directly block the light, affecting the permeability and detail performance of the picture, resulting in a blurred picture and a reduced monitoring effect.
