Description

Technical Field

[0001] The utility model relates to the technical field of protective nets, in particular to an acoustic and optical protective net for construction operations under high-voltage lines. Background Art

[0002] High-voltage lines refer to high-voltage cables or wires used to transmit electricity. They are usually used to transmit electricity from power plants to substations and then distribute it to various users or industrial areas. The voltage of high-voltage lines is generally above several thousand volts (kV). Due to the high voltage of high-voltage lines, they cannot be accidentally touched. Therefore, when workers need to work under high-voltage lines, they need to set up safety nets above the construction site and below the high-voltage lines to achieve a safe isolation and protection effect for the construction work area.

[0003] The existing construction protection net is composed of a simple combination of columns and protection nets. Although a protection net is set on the upper end of the construction equipment for isolation when adjusting the height position, the protection net is made of flexible material and cannot completely block the operation of the construction equipment. When the construction equipment is adjusted, the staff at the bottom of the equipment cannot observe the highest height position of the equipment in time. Once the height position of the equipment exceeds the isolation height of the protection net, it is easy to touch the high-voltage line and cause unnecessary damage. However, the existing protection net components have not made improvements to this problem, and the overall safety effect is poor. Utility Model Content

[0004] The purpose of the present utility model is to solve the above-mentioned problem and propose an acoustic and optical protection net for construction operations under high-voltage lines, which improves the existing construction protection net composed of a simple combination of columns and protection nets. Although a protection net is set on the upper end of the construction equipment for isolation when the height position is adjusted, the protection net is made of flexible material and cannot completely block the operation of the construction equipment. When the construction equipment is raised, the staff at the bottom of the equipment cannot observe the highest height position of the equipment in time, and once the height position of the equipment exceeds the isolation height of the protection net, it is easy to touch the high-voltage line and cause unnecessary damage.

[0005] A sound and light protection net for construction work under high-voltage lines, comprising columns and a support frame: the columns are symmetrically arranged in two groups, with two columns in each group, and a support frame is connected between the side outer walls of two adjacent columns at the top positions, a monitoring alarm mechanism is provided in the middle position of the columns in a single group, a reinforcement support mechanism is provided at the bottom end of the columns, and an auxiliary limit mechanism is provided above the support frame;

[0006] The monitoring and alarm mechanism includes a limit support, a positioning thread groove, a positioning bolt, a positioning box, an ultrasonic sensor, an alarm, a controller and a power supply. The external sleeves of the two columns are connected to the limit support. A positioning thread groove is provided on the side outer wall of the limit support. A limit thread groove of the same size is provided on the side outer wall of the column at the position of the positioning thread groove. The positioning thread groove and the positioning bolt are threadedly installed. A positioning box is provided on the top outer wall of the limit support at the middle position. An ultrasonic sensor and an alarm are installed on the side outer wall of the positioning box, and a controller and a power supply are provided on the bottom inner wall of the positioning box.

[0007] Preferably, the reinforced support mechanism includes a support base and an auxiliary support member. The bottom outer wall of the column is provided with a support base, and the side outer wall of the column at the bottom position is surrounded by auxiliary support members at equal intervals. The bottom outer wall of the auxiliary support member is connected to the top outer wall of the support base.

[0008] Preferably, two groups of cylindrical grooves are symmetrically formed on the outer wall of the top end of the support base, and ground nails are arranged inside the cylindrical grooves.

[0009] Preferably, the auxiliary support member is configured as a triangular structure.

[0010] Preferably, the auxiliary limiting mechanism includes a protective outer frame, a first clamping part and a second clamping part. The top outer walls of the two groups of columns are clamped and installed with a protective outer frame. The protective outer frame is provided with a hollow structure, and a protective net is connected between the top frame walls of the protective outer frame. The protective outer frame is provided with a first clamping part at a position above the frame edge, and the support frame is provided with a second clamping part in the hollow space near the top position.

[0011] Preferably, the bottom outer wall of the first clamping part and the top outer wall of the second clamping part are both provided with elastic contact pads, and the top outer walls of the first clamping part and the second clamping part are both symmetrically provided with two sets of docking thread grooves.

[0012] Preferably, a nut block is provided on the outer wall of the bottom end of the second clamping part located at the docking thread groove position, a fastening bolt is threadedly installed inside the docking thread groove of the first clamping part, and a threaded installation is formed between the nut block and the fastening bolt.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the sound and light protection net for construction work under the high-voltage line is in use, an ultrasonic sensor is installed near the top of the column to detect the height position of the protection net and the construction machinery. Once the maximum height of the construction machinery reaches the monitoring height range of the ultrasonic sensor, the ultrasonic sensor emits a sound wave and receives the reflected signal from the outer wall of the equipment. The alarm will sound through the component transmission control, thereby reminding the staff that the height position of the construction equipment has reached the critical value and needs to be adjusted in time. Compared with the general protection net that only achieves the effect of isolation fence, the above design is more flexible and safer as a whole, and can timely reflect the height position of the construction equipment to prevent the equipment from being raised or lowered too high and contacting the high-voltage line. At the same time, it eliminates the defect of inaccurate observation by the naked eye, and has a good overall practical effect.

[0015] 2. When the sound and light protection net for construction work under the high-voltage line is in use, a mechanism component is set at the bottom of the column so that the ground nails can be inserted into the stratum to reinforce the column, so that it will not move easily after installation. At the same time, a triangular structure support component is set at the bottom of the column, and the installation stability of the column is reinforced by using the principle of stability of the triangle. The overall structural design is simple and the practical effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

Once the highest height of the construction machinery reaches the monitoring height range of the ultrasonic sensor 35, the ultrasonic sensor 35 emits sound waves and receives the reflected signal from the outer wall of the equipment, and at the same time transmits the information to the controller 37. Then the controller 37 will automatically control the alarm 36 to light up and sound a warning sound, thereby reminding the staff that the height of the construction machinery has reached the critical height value and needs to be lowered in time to avoid hitting the high-voltage line. The power supply component 38 here is set to output power to the ultrasonic sensor 35, alarm 36 and controller 37.

The installation of the four columns 1 is the same.

[0027] The auxiliary support member 42 is configured as a triangular structure; the principle that a triangle has stability is utilized here so that the auxiliary support member 42 has the effect of reinforcing the support of the column 1 .

At this time, the elastic contact pad 54 is squeezed and slightly deformed, and the protective outer frame 51 and the support frame 2 are tightly installed together.

[0029] When the present invention is in use, when it is necessary to install the column 1 to the designated construction site, it is only necessary to adjust the column 1 to a suitable position and place it on the designated ground position, and then use the ground nail 44 to pass through the cylindrical groove 43 from top to bottom to reach the inside of the stratum to complete the installation of the column 1, and the same applies to the installation of the four columns 1; then the protective outer frame 51 and the protective net inside it are installed above the column 1, and at this time it is only necessary to clamp the protective outer frame 51 to the outside of the four columns 1 from top to bottom, and then adjust the first clamping part 52 to a suitable position and place it above the protective outer frame 51, and simultaneously pass the second clamping part 53 through the gap between the support frame 2 and arrange it correspondingly under the first clamping part 52, and then tighten the fastening bolt 57 from top to bottom through the two sets of docking thread grooves 55 and the nut block 56, at this time the elastic contact pad 54 is squeezed and slightly deformed, and the protective outer frame 51 and the support frame 2 are tightly installed together;
