Description

Technical Field

[0001] The utility model relates to the technical field of mine ventilation wind speed sensor installation equipment, in particular to a wind speed sensor installation bracket. Background Art

[0002] Benefiting from the progress of chip technology, the measurement accuracy of mine wind speed sensors in my country has been greatly improved. For underground coal mines, the data required by the mine is the average wind speed of the tunnel section. Although the sensor itself (especially the point-mounted wind speed sensor) has a high measurement accuracy, the measured data only represents the wind speed at the sensor installation location and cannot represent the average wind speed in the tunnel. To solve this problem, the industry has proposed the "average wind speed circle" theory in recent years. The wind speed sensor is installed on the average wind speed circle of the tunnel, and the data monitored by the sensor can represent the average wind speed in the tunnel.

[0003] The resulting problem is that in the actual installation process, in order to install the wind speed sensor at the average wind speed circle position, the wind speed sensor position needs to be constantly adjusted. The traditional wind speed sensor installation method is to repeatedly install and remove the wind speed sensor until the wind speed measured at the last installed wind speed sensor position meets the requirements. During later maintenance, when the tunnel is deformed due to the influence of mine pressure, the average wind speed in the tunnel changes. At this time, the wind speed sensor position needs to be adjusted. At this time, the wind speed sensor still needs to be removed and reinstalled, which is troublesome and inefficient.

[0005] The utility model aims to provide a wind speed sensor mounting bracket to solve the problem that the existing mounting bracket wind speed sensor mounting position adjustment method is relatively complicated when installing the lane wind speed sensor proposed in the above background technology.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind speed sensor mounting bracket, which includes a top plate fixing bracket, a connecting bracket, a fixing stud A, an expansion screw and a wind speed sensor device, wherein the top plate fixing bracket is an "L"-shaped metal plate, a small hole is provided at one end of the fixing bracket, the expansion screw passes through the small hole, and the top plate fixing bracket is fixed on the top plate of the tunnel, and an adjustment hole is provided at the other end of the top plate fixing bracket. The functions of the adjustment hole are: first, to fix the connecting bracket on the top plate fixing bracket, and second, the installation angle of the connecting bracket can be adjusted through the adjustment hole.

[0008] Preferably, the connecting bracket is a metal plate with screw holes and adjustment buckles. The screw holes on both sides of the connecting bracket are used to connect with other connecting brackets, top plate fixing bracket and wind speed sensor device fixing bracket through fixing studs A, and the middle row of screw holes is used to connect with the top plate fixing bracket through fixing studs A.

[0009] Preferably, the connecting bracket adjustment buckle refers to the groove formed in the middle of the connecting bracket after cutting, and its function is to hang the wind speed sensor device fixing bracket on the connecting bracket through the fixing stud A, and the wind speed sensor device fixing bracket can be moved up and down to the corresponding adjustment buckle as needed.

[0010] Preferably, the fixing stud A is composed of a fixing stud A and a nut, and its function is to connect the fixing bracket, the connecting bracket and the wind speed sensor device fixing bracket. The expansion screw is a metal accessory used to fix the top plate fixing bracket to the tunnel top plate.

[0011] Preferably, the back of the wind speed sensor device fixing frame has a protruding fixing stud B. When the wind speed sensor device fixing frame is spliced ​​with the connecting bracket, the fixing stud B on the back of the wind speed sensor device fixing frame passes through the adjusting buckle groove of the connecting bracket and is fixed with a nut. The bottom end of the wind speed sensor device fixing frame extends outward with a limiting groove, which is used to support the wind speed sensor device and fix it; the top of the wind speed sensor device fixing frame has a detachable limiting card, which is connected to the wind speed sensor device fixing frame through the fixing stud A. When the wind speed sensor device is installed, the limiting card is removed by removing the fixing stud A. After the wind speed sensor device is placed in the wind speed sensor device fixing frame, the limiting card is fixed to the wind speed sensor device fixing frame through the fixing stud A, thereby limiting the outward movement of the top of the wind speed sensor device.

[0012] Preferably, when the wind speed sensor device is installed, the wind speed sensor device fixing frame and the connecting bracket are fixed by passing the fixing stud B on the back of the wind speed sensor device fixing frame through the adjustment buckle groove of the connecting bracket and fixing it with a nut, the fixing stud A between the wind speed sensor device fixing frame and the limit card is removed, the wind speed sensor device is embedded in the limit groove of the wind speed sensor device fixing frame, and then the wind speed sensor device fixing frame and the limit card are fixed by the fixing stud A, and the connecting bracket where the wind speed sensor device is located and other connecting brackets are spliced ​​by the fixing stud A. The specific splicing method is to fix it with the fixing stud A through the screw holes on both sides of the connecting bracket. The specific number of connecting brackets to be spliced ​​is determined according to the actual lane conditions at the installation location of the wind speed sensor device.

[0013] Preferably, after the connection bracket is spliced, the connection bracket is connected and fixed to the top plate fixing frame by fixing studs A.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Compared with the traditional wind speed sensor without a bracket, the bracket provided by the utility model can flexibly adjust the installation position of the wind speed sensor in the tunnel. The installation position of the wind speed sensor is difficult to be installed in place at one time, and the installation position of the wind speed sensor needs to be adjusted continuously. When the traditional wind speed sensor is not equipped with a mounting bracket, the position can only be adjusted by repeatedly installing and disassembling the wind speed sensor, which has a large construction workload and low efficiency. When using the wind speed sensor mounting bracket, it is only necessary to adjust the position of the wind speed sensor fixing bracket on the connecting bracket to adjust the buckle, which is simple to operate and improves efficiency. In addition, affected by the pressure of the mine, the tunnel surrounding rock is prone to deformation, which will further affect the average wind speed of the tunnel. At this time, the position of the wind speed sensor needs to be adjusted. Similarly, at this time, it is only necessary to adjust the adjustment buckle position of the wind speed sensor fixing bracket on the connecting bracket without disassembling the wind speed sensor for reinstallation, which saves time and effort.
