[0002] When constructing the bottom of a cross-river dam, due to the huge volume of the dam and its U-shaped structure with a narrow bottom and a wide top, the lighting devices generally set on the ground cannot meet the lighting requirements for night construction. In order to achieve lighting at the construction position, usually suspension wires spanning the dam are set on both banks of the dam, and then the lighting devices are suspended on the suspension wires to illuminate the construction position at the bottom of the dam. In this way, the light shines vertically downward, and the lighting range is wide and the effect is good.

[0003] However, if after the lighting device is suspended above the dam body, it is found that the position of the lighting device is inappropriate or the construction position changes, then the lighting device and the suspension wire need to be retracted. After adjusting the position of the lighting device on the suspension wire, it is then re-suspended; thus, it can be seen that during the construction of the bottom of a cross-river dam, the position adjustment operation of the lighting device is complex and labor-consuming. Therefore, a lighting device for the construction of the bottom of a cross-river dam with adjustable position is needed to solve the above-mentioned technical problems. Summary of the Invention

[0022] In order to describe the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings.

[0023] In the following description, specific example details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0024] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or their combinations.

[0025] Please refer to Figure 1, this application provides a remotely adjustable lighting device for cross-river dam bottom construction, which includes a driving wheel 1 and a detour wheel 2. The driving wheel 1 and the detour wheel 2 are respectively arranged on both banks of the dam; a ring-shaped load-bearing cable 3 is arranged between the driving wheel 1 and the detour wheel 2. One end of the load-bearing cable 3 moves around the driving wheel 1 under the drive of the driving wheel 1, and the other end of the load-bearing cable 3 moves synchronously around the detour wheel 2; it also includes a lighting part 4, and the lighting part 4 is provided with a fixing plate 41 fixedly connected to the load-bearing cable 3; the driving wheel 1 drives the load-bearing cable 3 to move, and the traction of the load-bearing cable 3 on the fixing plate 41 is used to realize the position movement of the lighting part 4. By changing the rotation direction of the driving wheel, the moving direction of the lighting part can be adjusted; when the driving wheel rotates to move the lighting part to the construction area that needs lighting, the operation is simple and convenient.

[0026] Please refer to Figure 2 , the driving wheel 1 is fixedly arranged on the ground. The driving wheel 1 includes a left wheel 11 and a right wheel 12. An annular clamping cavity 13 is formed between the edges of the left wheel 11 and the right wheel 12. The load-bearing cable 3 is arranged in the annular clamping cavity 13. In this embodiment, the driving wheel forms a clamping cavity, and the load-bearing cable rotates in the clamping cavity, restricting the movement range of the load-bearing cable and preventing the load-bearing cable from deviating in direction.

[0027] Furthermore, in this embodiment, a number of raised structures are provided on the surface of the annular clamping cavity 13 in contact with the load-bearing cable 3. The provision of the raised structures can increase the friction between the driving wheel and the load-bearing cable and prevent the load-bearing cable from sliding on the driving wheel.

[0028] The power source of the driving wheel can be manual driving, hydraulic driving or motor driving. Please refer to Figure 2 , in this embodiment, the power source of the driving wheel 1 is a motor 5. A driving wheel shaft 14 is provided at the center of the driving wheel 1, and the driving wheel shaft 14 is connected to the output end of the motor 5 through a speed reducer 51. The advantages of using a motor drive are high power, high efficiency, smooth driving, etc. At the same time, since electric drive can cooperate with a centralized control system, the applicable range is very wide.

[0029] In this application, the fixing plate and the load-bearing cable can be connected through a fixed cable gripper or a detachable cable gripper.

[0030] Please refer to Figure 1 and 3 , in this embodiment, the fixing plate 41 and the load-bearing cable 3 are detachably and fixedly connected through a spring clamp 411. The clamping part of the spring clamp 411 clamps the load-bearing cable 3, and the spring clamp 411 is fixedly connected to the fixing plate 41 through a plurality of fixing rods 412.

[0031] In a further solution, a connecting column 413 is further provided at the center of the side of the clamping portion close to the fixed disk 41; one ends of a plurality of fixing rods 412 are connected to the column surface of the connecting column 413, and the other ends are obliquely connected to the fixed disk 41, so that any two adjacent fixing rods 412 and the fixed disk 41 form a triangular-like structure; the connection stability between the fixed disk 41 and the spring clamp 411 can be significantly increased through the formed multiple groups of triangular-like structures, so as to be able to hang more firmly on the load-carrying cable 3.

[0032] In this application, a tensioning device needs to be provided at one end where the deflecting pulley is located to keep the load-carrying cable between the driving pulley and the deflecting pulley under appropriate tension. In the prior art, the load-carrying cable can be tensioned by a hydraulic press, a tensioning trolley or a weight can be provided on the load-carrying cable. When using a hydraulic press to tension the load-carrying cable, the tensioning trolley is pulled by the hydraulic press, and the tension of the cableway can be controlled by adjusting the hydraulic press. The operation is relatively refined, but the equipment structure is complex and the cost is relatively high. It is generally used for equipment with a relatively large load-carrying weight of the load-carrying cable.

[0033] Please refer to Figure 5 , in a specific embodiment, the tensioning device is a weight tensioning device 6. The deflecting pulley 2 is installed on a mounting seat 21 provided with rollers. The weight tensioning device 5 includes a vertically suspended weight 61 and a pulley block 62. The weight 61 is connected to the mounting seat 21 through a rope 63. The rope 63 passes through the pulley block 62 to change the direction of the pulling force. The vertically suspended weight is connected to the mounting seat. Since the weight of the weight can be a certain value and the number of weights can be increased according to the actual situation, the tension and the pulling force of the load-carrying cable are constant. At the same time, the weight tensions by its own weight and can automatically compensate for the elongation of the load-carrying cable. When the load-carrying cable is slack, the weight pulls the mounting seat backward by its own weight to make the load-carrying cable return to the taut state. The weight tensioning device is relatively simple in structure compared with other tensioning methods. And since there is no too high requirement for the moving speed of the lighting portion in this application, the tensioning of the load-carrying cable by the weight tensioning device can already enable the load-carrying cable to better bear the weight of the lighting portion. Therefore, selecting this device can reduce the production cost of the equipment in this application.

[0034] The lamps of the lighting portion in the present utility model can be incandescent lamps, fluorescent lamps, LED lamps or a combined device using a variety of lamps. In this embodiment, after the lighting portion in this application is adjusted to the construction area, in order to better illuminate the construction site, the angles of the lamps of the lighting portion can be further adjusted.

[0035] Please refer to Figure 1 and Figure 3, the lighting unit further includes a movable disk 42, which is connected to the fixed disk 41 by three adjusting connecting members. On one side of the movable disk 42 away from the fixed disk 41, there is at least one group of lighting lamps 422; on the fixed disk 41, there is a first communication device for adjusting the length of the adjusting connecting member. The first communication device is wirelessly connected to a second communication device, and the second communication device sends a signal to the first communication device to control the movement of the adjusting connecting member to change the irradiation angle of the lighting lamp, so that the movable disk 42 deflects and moves, thereby changing the irradiation angle of the lighting unit and better illuminating the construction area at the bottom of the dam, and the operation and adjustment are more convenient.

[0036] The adjusting connecting member can be implemented with a structure having telescopic characteristics, such as a cylinder, an electric cylinder, or a turbine with a cable. Further, please refer to Figure 4 , the adjusting connecting member is a telescopic rod 421. One end of the telescopic rod 421 is fixedly connected to the fixed disk 41, and the other end is hinged to the movable disk 42. In this embodiment, the telescopic rod is a rigid structure, which can also provide a good connection function between the fixed disk and the movable disk when adjusting the angle of the movable disk, making the connection more stable.

[0037] The operation process of the present invention: After the driving wheel and the bypass wheel are respectively installed on both banks of the dam body, the two ends of the load-carrying cable are respectively sleeved on the driving wheel and the bypass wheel, and then the lighting unit is clamped to the load-carrying cable on the side of the driving wheel. Start the motor of the driving wheel, and the load-carrying cable starts to drive the lighting unit to move. When it reaches the appropriate position, the motor can be turned off;

[0038] After the lighting unit reaches the appropriate position, according to the lighting requirements of the construction area, a signal is sent from the second communication device to the first communication device to adjust the movement of the telescopic rod of the lighting unit until the lighting angle of the lighting lamp of the lighting unit is appropriate, and the operation is completed.

[0039] The advantages of the present invention are as follows:

[0040] 1) By rotating the driving wheel, the position adjustment of the lighting unit can be completed. Adjust the rotation direction of the driving wheel to move the lighting unit to the appropriate area and better illuminate the construction area.

[0041] 2) The lighting unit is provided with an adjusting connecting member, which can change the illumination direction of the lighting lamp, making the lighting more suitable for the construction environment at the bottom of the dam.

[0042] 3) Motor drive is adopted, the drive is stable, and it is beneficial to centralize the drive of the driving wheel and the telescopic rod of the lighting unit to the control system for unified control.

[0043] The above only discloses several specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
