Description

Technical Field

[0001] The utility model relates to the technical field of tunnel water level detection, in particular to a tunnel water level detection device. Background Art

[0002] Tunnel water accumulation refers to the phenomenon of rising water levels and water accumulation inside the tunnel due to poor drainage, water seepage or other reasons. Tunnel water accumulation not only affects driving safety and causes traffic accidents, but may also damage the tunnel structure and reduce the service life of the tunnel. Therefore, timely and accurate detection of the water level inside the tunnel is of great significance to ensure traffic safety and the normal operation of the tunnel.

[0003] At present, tunnel water level detection mainly adopts two methods: manual inspection and traditional water level detection device. Manual inspection has problems such as low efficiency, high risk, easy omission, etc., which can hardly meet the needs of modern tunnel management. Although the traditional water level detection device has realized automatic detection, it also has some shortcomings:

[0004] Inconvenient maintenance: Traditional water level detection devices usually install sensors fixedly inside the tunnel. When the sensor needs to be repaired, adjusted or replaced, workers are required to enter the tunnel to operate, which is not only time-consuming and labor-intensive, but also poses certain safety hazards.

[0005] Therefore, this invention proposes a water level detection device for tunnel water accumulation to solve the above problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, the utility model aims to provide a device for detecting water level of water accumulation in a tunnel.

[0015] The screw cap is distributed on the right side of the lifting slide block, and the screw cap is connected to the right end of the double-headed screw rod.

[0016] Preferably, the overall cross-section of the lifting slider is set to be U-shaped, and the two sides of the lifting slider are attached to the left and right side walls of the vertical mounting frame. The left and right side surfaces of the vertical mounting frame are both provided with vertically distributed side guide rails, and the insides of the side guide rails on both sides are installed with guide components that cooperate with the lifting operation of the lifting slider.

[0017] Preferably, the guide assembly specifically includes the following structure:

[0018] A guide rod installed inside the side guide rail;

[0019] The guide sleeve is slidably sleeved on the guide rod, and the outer tube wall of the guide sleeve is connected with the inner wall of the bent end on the same side of the lifting slider.

[0020] Preferably, side mounting ears are provided on both left and right sides of the vertical mounting frame, and the vertical mounting frame is attached to the side wall of the tunnel and fixed by the side mounting ears and a plurality of fixing bolts.

When the radar water level detector needs to be repaired or replaced, it can be easily operated by simply controlling the drive motor to lower the radar water level detector to the bottom of the vertical mounting frame, which greatly improves the efficiency and convenience of maintenance.

[0023] The setting of the clamping drive mechanism enables the radar water level detector to be firmly clamped between the clamping positioning plates on both sides. At the same time, by rotating the screw cap, the radar water level detector can be easily loosened for easy disassembly and maintenance. This clamping and loosening design avoids the cumbersome disassembly and assembly process and improves the speed and efficiency of maintenance.

[0024] In summary, through the designs of the lifting and position - adjusting mechanism, the clamping drive mechanism, etc., the water - level detection device for tunnel water accumulation greatly improves the maintenance convenience of the radar water - level detector.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Please refer to the instruction manual Figures 1-7 The utility model provides a water level detection device for tunnel water accumulation, including a vertical mounting frame 1 and a radar water level detector 6. A vertical mounting groove 11 is arranged on the front of the vertical mounting frame 1, and a lifting and positioning mechanism 2 is installed inside the vertical mounting groove 11 to drive the radar water level detector 6 to descend to the bottom for easy maintenance. The positioning end of the lifting and positioning mechanism 2 is connected to the lifting slider 3 arranged on the front of the vertical mounting frame 1, and a horizontal mounting groove 31 is arranged on the front of the lifting slider 3. A clamping drive mechanism 5 is installed inside the horizontal mounting groove 31, and the driving ends on both sides of the clamping drive mechanism 5 are connected to the clamping positioning plates 4, and the radar water level detector 6 is clamped between the clamping positioning plates 4 on both sides.

[0044] Specifically, the lifting and positioning mechanism 2 includes a driving motor 21 installed at the bottom end of the vertical mounting groove 11, a driving screw 22 connected to the output end of the driving motor 21, and a first screw sleeve 23 threadedly sleeved on the driving screw 22. The front wall of the first screw sleeve 23 is connected to the center of the inner side of the lifting slider 3. By controlling the rotation of the driving motor 21, the driving screw 22 is driven to rotate, and then the first screw sleeve 23 is moved up and down along the driving screw 22, thereby driving the lifting slider 3 to move up and down, and realizing the lifting and positioning of the radar water level detector 6.

[0045] The clamping drive mechanism 5 includes a double-headed screw rod 51 installed inside the horizontal installation groove 31, second screw rod sleeves 52 correspondingly threadedly sleeved on the left and right ends of the double-headed screw rod 51, and screw caps 53 distributed on the right side outside the lifting slider 3. The front side tube walls of the second screw rod sleeves 52 on both sides are respectively butted against the clamping and positioning plates 4 on both sides, and the screw cap 53 is butted against the right end of the double-headed screw rod 51. By rotating the screw cap 53, the double-headed screw rod 51 is driven to rotate, so that the second screw rod sleeves 52 on both sides move towards or away from each other, thereby realizing the clamping or loosening of the radar water level detector 6 through the clamping and positioning plates 4 on both sides.

[0046] The overall cross-section of the lifting slider 3 is set in a U shape, and both sides of the lifting slider 3 are attached to the left and right side walls of the vertical installation frame 1. Vertical side guide rails 12 distributed vertically are arranged inside the left and right side surfaces of the vertical installation frame 1, and guide components 7 for cooperating with the lifting and lowering operations of the lifting slider 3 are installed inside both side guide rails 12. The guide component 7 includes a guide rod 71 installed inside the side guide rail 12 and a guide sleeve 72 slidably sleeved on the guide rod 71. The outer tube wall of the guide sleeve 72 is butted against the inner wall of the same-side bent end of the lifting slider 3. Through the arrangement of the guide component 7, the lifting slider 3 is more stable during the lifting process and is not prone to tilting.

[0047] Side installation ears 13 are arranged on both the left and right sides of the vertical installation frame 1. The vertical installation frame 1 is attached to the tunnel side wall and fixed to the tunnel side wall through the side installation ears 13 and a plurality of fixing bolts 14, so that the entire device is stably installed inside the tunnel.

[0048] The working principle of this tunnel water accumulation water level detection device is as follows:

[0049] Installation and fixation: Attach the vertical installation frame 1 to the tunnel side wall and firmly install it inside the tunnel through the side installation ears 13 and the fixing bolts 14.

[0050] Installation of the radar water level detector: Place the radar water level detector 6 between the clamping and positioning plates 4 on both sides. By rotating the screw cap 53, the double-headed screw rod 51 is driven to rotate, so that the second screw rod sleeves 52 on both sides move towards each other, thereby clamping and fixing the radar water level detector 6 through the clamping and positioning plates 4 on both sides.

[0051] Lifting and adjusting the position of the radar water level detector: By controlling the rotation of the driving motor 21, the driving screw 22 is driven to rotate, and then the first screw sleeve 23 is moved up and down along the driving screw 22, thereby driving the lifting slider 3 connected to the first screw sleeve 23 to move up and down. Since the radar water level detector 6 is fixed on the lifting slider 3, it can move up and down with the lifting slider 3 to achieve the lifting and adjusting of the radar water level detector 6. During the lifting process, the guide sleeve 72 in the guide assembly 7 is connected to the lifting slider 3 and slides along the guide rod 71, which plays a guiding and stabilizing role, so that the radar water level detector 6 is more stable during the lifting process.

[0052] Disassembly and maintenance of radar water level detector: When the radar water level detector 6 needs to be repaired or replaced, firstly, the driving motor 21 is controlled to lower the radar water level detector 6 to the bottom of the vertical mounting frame 1 for easy operation. Then, the double-headed screw 51 is driven to rotate by rotating the screw cap 53, so that the second screw sleeves 52 on both sides move backwards, thereby loosening the radar water level detector 6 by clamping the positioning plates 4 on both sides. Finally, the radar water level detector 6 can be easily removed for repair or replacement.

[0053] Restore working state: After the repair or replacement is completed, follow the operations in steps 2 and 3 to reinstall the radar water level detector 6 and adjust it to a suitable working position to resume normal water level detection work.
