Description

Technical Field

[0001] The utility model relates to the technical field of flow monitoring cameras, in particular to a flow monitoring camera. Background Art

[0002] In the fields of water conservancy projects, urban management, and environmental protection, flow monitoring cameras play a vital role. Traditional flow monitoring methods mainly rely on manual observation or installation of fixed monitoring equipment. These methods have problems such as narrow monitoring range, low monitoring accuracy, and poor real-time performance. In order to solve these problems, flow monitoring cameras came into being. This type of camera is usually installed at the edge of the water or on a bridge. It monitors the water surface velocity and flow in real time through the camera. It has the advantages of wide monitoring range, high monitoring accuracy, and strong real-time performance.

[0003] Current shortcomings:

[0004] Poor rotation performance: The rotation performance of existing flow monitoring cameras is limited, often due to the roughness of the installation perforations or improper selection of cantilever materials, which leads to increased friction during rotation, affecting the accuracy and stability of monitoring.

[0005] The structure is bulky and inflexible: The structure design of some traffic monitoring cameras is bulky and the materials used are unreasonable, which makes it difficult for the equipment to maintain sufficient lightness and flexibility while carrying the monitoring camera, limiting its application scope in different environments.

[0006] Difficulty in position adjustment: The existing flow monitoring camera has a fixed structure. Since the distance between some river banks and the water's edge is uncertain, it may be impossible to monitor the water surface flow.

[0007] Inconvenient operation and maintenance: Existing flow monitoring cameras have certain difficulties in operation and maintenance. The traditional flow monitoring camera has a fixed structure and the maintenance operation requires technicians to use external tools to lift it to a high place for maintenance.

[0008] Therefore, this solution specifically proposes a flow monitoring camera to solve the above problems. Utility Model Content

[0016] Preferably, the transmission ratio between the driving worm and the transmission worm gear is set to 5:1.

[0017] Preferably, the position adjustment mechanism specifically includes the following structure:

[0018] A second drive motor installed inside the cantilever near the rotating end;

[0019] A driving screw connected to the output end of the second driving motor;

[0020] A screw rod sleeve is threadedly sleeved on the driving screw rod, and a bottom tube wall of the screw rod sleeve is connected to the top of the monitoring camera.

[0022] Preferably, a mounting seat is installed at the bottom end of the support.

[0023] The beneficial effects of the utility model are embodied in:

[0024] Precise position adjustment: The position adjustment mechanism inside the cantilever can accurately adjust the position of the camera on the cantilever, allowing the monitoring camera to slide back and forth flexibly to adapt to the monitoring needs of different water surface distances from the shore, thereby improving the accuracy and adaptability of monitoring.

[0025] Rotation drive mechanism design: The cantilever rotation drive mechanism can drive the cantilever to rotate to a vertical state for monitoring operations, or retract it to the inside of the installation perforation for maintenance and repair.

[0037] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that if the utility model embodiments involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] Please refer to the instruction manual Figure 1-Figure 5 The utility model provides a flow monitoring camera, including:

[0041] The center of the pillar 1 is provided with a mounting through hole 2 which is distributed along the length direction of the pillar 1 and penetrates front and back. The mounting through hole 2 ensures that the cantilever 3 can smoothly rotate around the top thereof. The inner wall of the mounting through hole 2 is precisely machined to avoid friction of the cantilever 3 during movement.

[0042] A cantilever 3 is arranged inside the installation through hole 2, and the top of the cantilever 3 is rotatably mounted on the top of the inside of the installation through hole 2 and can be perpendicular to the pillar 1. The cantilever 3 is made of a light but high-strength material to ensure that the structure remains light and flexible while carrying the monitoring camera 4. The rotating end of the cantilever 3 is designed with a precision bearing to achieve smooth and unimpeded rotational movement.

[0043] The cantilever 3 is internally installed with a position adjustment mechanism 8 for driving the monitoring camera 4 to slide forward and backward on the cantilever 3. The position adjustment mechanism 8 includes a second drive motor 81, a drive screw 82 and a screw sleeve 83. The second drive motor 81 provides power, and the drive screw 82 cooperates with the screw sleeve 83 through the thread, so as to achieve precise position adjustment of the monitoring camera 4 on the cantilever 3, thereby enabling the monitoring camera 4 to extend forward from the shore and transfer to the water surface to be tested, with stronger adaptability.

[0044] The outer side of the top of the pillar 1 is installed with a cantilever rotation drive mechanism 5 for driving the cantilever 3 to rotate to a state perpendicular to the pillar 1 or to be recovered to the installation through hole 2 for operation. When the cantilever rotation drive mechanism 5 drives the cantilever 3 to rotate to a state perpendicular to the pillar 1, the monitoring camera 4 can be started to perform the water surface flow monitoring operation. When the cantilever rotation drive mechanism 5 drives the cantilever 3 to rotate downward to the inside of the installation through hole 2, the monitoring camera 4 is also recovered to the inside of the installation through hole 2, which is convenient for subsequent operators to perform maintenance operations. The cantilever rotation drive mechanism 5 includes a first drive motor 51, a drive worm 52, a transmission turbine 53 and a drive shaft 54. The first drive motor 51 transmits the rotational power to the drive shaft 54 ​​through the meshing of the drive worm 52 and the transmission turbine 53, thereby driving the rotation of the cantilever 3. The transmission ratio is set to 5:1 to ensure that the rotation of the cantilever 3 is smooth and controllable.

[0045] An outer protective cover 6 is provided on the outer side of the top of the support 1, and the driving worm 52 and the transmission turbine 53 are both distributed inside the outer protective cover 6. The outer protective cover 6 is made of a material with strong weather resistance and corrosion resistance to protect the internal mechanical parts from the influence of the external environment, such as rain, dust and ultraviolet rays. The design of the outer protective cover 6 also takes ventilation and heat dissipation into consideration to ensure that the internal mechanical parts can still maintain a good working condition after a long period of operation.

[0046] The bottom end of the pillar 1 is provided with a mounting base 7 to increase the stability of the device. In addition, the mounting base 7 is installed on the ground by bolts.
