Description

Technical Field

[0001] The utility model relates to the technical field of anemometers, in particular to an anemometer that is convenient to use in tunnels. Background Art

[0002] With the development of highway traffic, more and more highway tunnels are being built to solve the problem of traffic congestion in travel and transportation. However, due to the environmental characteristics of the tunnel, such as strong airtightness and abnormal tension, it will cause changes in airflow, temperature and humidity to varying degrees, bringing many hidden dangers to vehicle driving. Among them, changes in wind speed and direction are one of the main causes of traffic safety accidents.

[0003] When measuring the wind speed inside a tunnel, the operator usually holds the anemometer for measuring the wind speed high up in a handheld manner. However, the position of the tunnel waist and arch crown is relatively high, and it is difficult to detect the wind speed at the tunnel waist and arch crown. Based on this, an anemometer that is convenient to use in tunnels is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, provide a convenient anemometer for use in a tunnel, and effectively solve the deficiencies of the prior art.

[0005] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides an anemometer for convenient use in a tunnel, comprising a hand-held limiting tube, three supporting tubes that can slide up and down are installed inside the limiting tube, and the three are threadedly connected in sequence end to end, a placing seat is installed at the top of the upper supporting tube, an anemometer body is installed inside the placing seat, a conical groove is opened at the top of the inner wall of the limiting tube, a conical clamping ring is installed inside the conical groove, which is sleeved on the outer wall of the supporting tube, a cover ring is threadedly connected to the top of the limiting tube for clamping the conical clamping ring, and a display screen electrically connected to the anemometer body is installed at the bottom of the outer wall of the limiting tube.

[0006] Preferably, any of the above schemes is that the limiting tube includes a lower hollow tube, a middle hollow tube and an upper hollow tube, and the three are threadedly connected in sequence end to end. By using this scheme, the limiting tube can be divided into three parts, which is convenient for users to assemble and use. At the same time, the overall size can be reduced in the later stage, which is convenient for users to carry and transport. At the same time, the number of hollow tubes is increased and assembled with the lower hollow tube and the upper hollow tube, which makes it easy to change the length of the limiting tube for wind speed measurement in tunnels of different sizes.

[0007] Preferably, any of the above schemes has a protective handle connected to the bottom end of the outer wall of the limit tube, a screen mounting seat is installed on the outer wall of the limit tube close to the protective handle, and the display screen is installed inside the screen mounting seat. The protective handle in this scheme provides a holding position for the user, and the user lifts the limit tube and makes the limit tube in a relatively vertical state, while the screen mounting seat is installed on the position of the limit tube close to the protective handle, so that the user can observe the changes in the numbers on the display screen after lifting the limit tube, thereby facilitating the user to record the wind speed data.

[0008] Preferably, any of the above schemes is that a plurality of through grooves are formed on the outer wall of the conical clamping ring, and the top surface of the conical clamping ring is higher than the top surface of the limiting tube. By using this scheme, the bottom end of the conical clamping ring can slide along the inside of the conical groove and move toward the middle position to clamp the support tube, thereby increasing the friction between the two and limiting the support tube. At the same time, the material of the conical clamping ring can be rubber. After the cover ring is loosened, the conical clamping ring is automatically moved upward under the action of its own elastic force, thereby reducing the friction between the support tube.

[0009] Preferably, any of the above schemes is that the bottom end of the placement seat is threadedly connected to the top end of the upper support tube, and a plurality of limiting protrusions are installed on both sides of the inner wall of the placement seat. The material of the plurality of limiting protrusions in this scheme can be silicone, which makes it easy to contact with the outer wall of the anemometer body, and at the same time protect the outer wall of the anemometer body, reduce the surface wear of the anemometer body, and provide a certain friction force, so that the anemometer body can be stably placed inside the placement seat.

[0010] Preferably, any of the above schemes is that the bottom end of the lower support tube is threadedly connected to a guide seat, the middle part of the outer wall of the guide seat is recessed inward, and a damping ring that slides relative to the inner wall of the limiting tube is installed at the recessed part. The damping ring in this scheme contacts the inner wall of the limiting tube, thereby limiting the bottom end of the lower support tube to prevent it from shaking inside the limiting tube. In addition, the damping ring and the inner wall of the limiting tube have a certain friction force. After the cover ring is loosened, the lower support tube is limited by this friction force to prevent the support tube from automatically falling along the inside of the limiting tube.

[0011] The utility model has the following advantages:

[0012] 1. The anemometer convenient for use in the tunnel is provided with a limit tube and three support tubes. The three support tubes are connected end to end in sequence and placed inside the limit tube. At the same time, a conical clamping ring and a cover ring for clamping are provided on the top of the limit tube. Then, the cover ring is loosened to reduce the friction between the conical clamping ring and the support tube, so that the user can adjust the length of the support tube entering the limit tube, thereby facilitating the overall length adjustment. Subsequently, the cover ring is tightened to lock it, so that the wind speed at the tunnel arch waist and arch top position can be measured through the anemometer body. The overall structure is simple and convenient for popularization and use.

[0013] 2. The anemometer for convenient use in the tunnel is equipped with a limit tube and three supporting tubes. The limit tube is composed of a lower hollow tube, a middle hollow tube and an upper hollow tube. The three supporting tubes are connected end to end in sequence. By increasing the number of hollow tubes and supporting tubes, the overall height can be adjusted to measure wind speeds in tunnels of different sizes, thereby improving the overall scope of application and operability.

[0025] The limiting tube 1 includes a lower hollow tube 101, a middle hollow tube 102 and an upper hollow tube 103, and the three are threadedly connected in sequence end to end. As an optional technical solution of the utility model, this makes it easy to divide the limiting tube 1 into three parts, which is convenient for users to assemble and use. At the same time, the overall size can be reduced in the later stage, which is convenient for users to carry and transport. At the same time, the number of hollow tubes 102 is increased, and they are assembled with the lower hollow tube 101 and the upper hollow tube 103, which makes it easy to change the length of the limiting tube 1 for measuring wind speed in tunnels of different sizes.
