Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, in particular to an anti-blocking highway tunnel drainage device. Background Art

[0002] With the continuous improvement of infrastructure, tunnels account for a large proportion of highways. Waterproofing and water control in tunnels are the difficulties in tunnel construction and maintenance. The perfection of drainage facilities is not only related to the life of tunnel structure, but also to the safety of tunnel operation.

[0003] Although the existing tunnel waterproof drainage structure can drain water out of the tunnel and prevent water from seeping into the track bed, it cannot further improve the drainage effect and cannot collect debris in the water while draining water. As a result, it is easy to get blocked when the rain is too heavy or it is used for a long time, causing water accumulation inside the tunnel, which in turn causes water to seep into the tunnel and cause deformation of the track bed, thus affecting the internal structure of the tunnel and traffic safety.

[0004] Therefore, there is an urgent need for a drainage device that can collect debris while draining water. Summary of the invention

[0005] The utility model aims to provide an anti-blocking highway tunnel drainage device, so as to at least solve the problem that the current drainage device cannot collect debris while draining water.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An anti-blocking highway tunnel drainage device comprises an upper cover plate, a collecting mechanism, a water delivery trough and a water delivery pipe, wherein the water delivery trough is arranged on both sides of a base layer, the water delivery pipe is arranged in the middle of the base layer and communicates with the water delivery troughs on both sides, and the upper cover plate is arranged above the water delivery trough and is arranged flush with the upper end surface of the base layer;

[0008] The collecting mechanism is arranged in the water trough, and the collecting mechanism includes a collecting component and an anti-clogging component. The anti-clogging component is arranged below the collecting component. An impeller is arranged below the collecting mechanism, which is used to make the collecting component move up and down above the anti-clogging component to prevent the collecting component from being blocked. A filter plate is inclined below the upper cover plate. After rainwater and debris are initially filtered by the upper cover plate, they fall onto the filter plate for secondary filtration. The debris on the filter plate slides along the filter plate to the collecting component of the collecting mechanism for collection, and the rainwater falling into the water trough flows into the water pipe for discharge.

[0009] Furthermore, the collecting assembly includes a collecting box, a replacement box and a collecting plate, the top of the collecting box is located on the upper end surface of the base layer, the bottom of the collecting box extends vertically into the water trough and the side is fixed on the side wall of the water trough, the replacement box is arranged in the collecting box, inlets are opened on both sides of the collecting box, the collecting plate is obliquely arranged on both sides of the collecting box, one end of the collecting plate is hinged to the side wall of the water trough away from the collecting box, and the other end extends into the replacement box through the inlet, and the debris sliding off the filter plate is collected into the replacement box through the collecting plate.

[0010] Furthermore, an adjusting rod is provided at the bottom of the collecting plate near one end of the inlet, and an inclined surface is provided at the bottom of the adjusting rod. The rotation of the impeller drives the adjusting rod and the collecting plate to move up and down.

[0011] Furthermore, a spring is installed between the bottom of the collecting plate and the lower side wall of the inlet, so as to limit the collecting plate when it moves up and down.

[0012] Furthermore, a plurality of filter holes are provided on the bottom of the replacement box, the bottom of the collection box and the collection plate.

[0013] Furthermore, the anti-clogging component includes a base plate and a plurality of plug rods. The base plate is arranged below the collecting plate and parallel to the collecting plate. The plurality of plug rods are arranged on the upper end surface of the base plate. When the collecting plate moves downward, the plug rods are correspondingly inserted into the filter holes to push out the debris in the filter holes to prevent the filter holes from being blocked.

[0014] Furthermore, a connecting pipe is provided between the water delivery trough and the water delivery pipe, and the connecting pipe is arranged at an angle.

[0015] Furthermore, the impeller is arranged at the water inlet at the end of the connecting pipe.

[0016] Furthermore, the higher end of the filter plate is fixed on the side wall opposite to the collection box in the water supply trough, and the lower end extends to the top of the collection plate, so that debris falling on the filter plate slides onto the collection plate through the inclined surface.

[0017] Furthermore, the upper cover plate is provided with a plurality of water inlet holes.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] 1. The utility model provides an upper cover plate, a filter plate, a collecting mechanism, a water trough and a water pipe, so that rainwater and debris are filtered initially by the upper cover plate and then fall onto the filter plate for secondary filtration. The debris on the filter plate slides along the filter plate to the collecting assembly of the collecting mechanism for collection, and the rainwater falling into the water trough flows into the water pipe for discharge, so that debris can be collected while draining water, thereby better improving the drainage effect and preventing debris from forming blockage when the rainwater is too heavy or used for a long time, causing water accumulation inside the tunnel, thereby seeping into the tunnel and affecting the internal structure of the tunnel and traffic safety.

[0020] 2. The utility model provides a collection box, a replacement box and a collection plate. The replacement box is installed in the collection box, so that the debris on the filter plate slides along the inclined filter plate to the collection plate, and then slides along the inclined collection plate to the replacement box, thereby facilitating the centralized cleaning of the debris in the replacement box.

[0021] 3. The utility model provides an adjusting rod and an impeller. The bottom of the adjusting rod is provided with an inclined surface, which makes it easier for the impeller to move the adjusting rod and reduces friction. The blades of the impeller squeeze the inclined surface at the bottom of the adjusting rod, so that the adjusting rod moves up and down, thereby driving the collecting plate connected to it to swing up and down around the hinge point, and can be reset by a spring. The up and down swinging of the collecting plate can make the debris slide into the replacement box more smoothly, avoiding the debris being left on the collecting plate. The impeller can also more efficiently deliver water to the water pipe, and can prevent the connection between the water trough and the connecting pipe from being blocked, thereby increasing the discharge speed.

[0022] 4. The utility model provides a bottom plate and an insertion rod. When the collecting plate moves downward to the maximum limit, the insertion rod on the bottom plate is correspondingly inserted into the filter hole of the collecting plate to push out the debris in the filter hole, thereby preventing the filter hole from being blocked by the debris.

[0040] Embodiment 1:

[0041] like Figure 1 As shown, an anti-clogging highway tunnel drainage device includes an upper cover plate 24, a collecting mechanism 3, a water trough 21 and a water pipe 22. The drainage device of this embodiment is arranged on both sides of the base layer 2 in the tunnel 1, the water troughs 21 are arranged on both sides of the base layer 2, the water pipes 22 are arranged in the middle of the base layer 2 and are connected with the water troughs 21 on both sides, a connecting pipe 23 is connected between the water trough 21 and the water pipe 22, and the connecting pipe 23 is arranged obliquely, the upper cover plate 24 is fixed above the water trough 21, completely covers the water trough 21 and is arranged flush with the upper end surface of the base layer 2, and a plurality of water inlet holes 25 are arranged on the upper cover plate 24.

[0042] By opening water troughs 21 on both sides of the base layer 2, water on the base layer 2 can enter the water trough 21 from the water inlet hole 25 of the upper cover plate 24. The upper cover plate 24 can initially filter larger debris. The accumulated water in the water trough 21 enters the water pipe 22 through the connecting pipe 23 and is discharged from the water pipe 22.

[0043] like Figure 2 , Figure 3 , Figure 7 As shown, the collecting mechanism 3 is arranged in the water trough 21, and the collecting mechanism 3 includes a collecting component and an anti-clogging component. The anti-clogging component is arranged below the collecting component. An impeller 5 is arranged below the collecting mechanism 3, and the impeller 5 is fixed at the water inlet at the end of the connecting pipe 23, and is used to move the collecting component up and down above the anti-clogging component to prevent the collecting component from being blocked.

[0044] Furthermore, by installing the impeller 5, water can be delivered to the water delivery pipe 22 more efficiently, and the connection between the water delivery trough 21 and the connecting pipe 23 can be prevented from being blocked, thereby increasing the discharge speed.

[0045] like Figure 4-Figure 5As shown, the collecting assembly includes a collecting box 31, a replacement box 32 and a collecting plate 33. The top of the collecting box 31 is located on the upper end surface of the base layer 2, and the top of the collecting box 31 is an opening. The bottom of the collecting box 31 penetrates the base layer 2 and extends vertically into the water trough 21, and the side of the collecting box 31 is fixed on the side wall of the water trough 21. The replacement box 32 is placed in the collecting box 31 for easy regular replacement and cleaning of collected debris. The collecting box 31 is provided with inlets 34 on both sides perpendicular to the side walls of the water trough 21. The inlet 34 is rectangular, and the collecting plates 33 are obliquely arranged on both sides of the collecting box 31. The higher end of the collecting plate 33 is hinged to the edge of the side wall of the water trough 21 away from the collecting box 31, and the lower end extends into the replacement box 32 through the inlet 34 to ensure that the debris on the entire filter plate 4 is collected. A spring 38 is connected between the bottom of the collecting plate 33 and the lower side wall of the inlet 34 to limit the collecting plate 33 when it moves up and down.

[0046] A filter plate 4 is obliquely provided below the upper cover 24. The filter plate 4 is located above the collecting plate 33. The length of the filter plate 4 is consistent with the length of the upper cover 24 to ensure that the debris filtered by the entire upper cover 24 is collected. The higher end of the filter plate 4 is fixed to the side wall opposite to the collecting box 31 in the water conveying trough 21, and the lower end extends to the top of the collecting plate 33. The filter plate 4 located at the collecting box 31 is close to the outer wall of the collecting box 31, so that the lower end of the filter plate 4 forms a concave shape at the collecting box 31, and the debris falling on the filter plate 4 slides onto the collecting plate 33 through the inclined surface.

[0047] The replacement box 32 is installed inside the collection box 31. First, part of the rainwater and debris are preliminarily filtered through the upper cover plate 24, and then fall onto the filter plate 4 for secondary filtration. The filter plate 4 separates water and debris, and the debris on the filter plate 4 slides along the inclined filter plate 4 to the collection plate 33, and then slides along the inclined collection plate 33 to the replacement box 32, so that the debris in the replacement box 32 can be cleaned up in a centralized manner.

[0048] The adjusting rod 35 is provided with an inclined surface 36 at the bottom of the adjusting rod 35, and the inclined surface 36 is provided to facilitate the impeller 5 to move the adjusting rod 35 more easily and reduce friction. When the impeller 5 rotates, the blades squeeze the inclined surface 36 at the bottom of the adjusting rod 35, so that the adjusting rod 35 moves up and down. The adjusting rod 35 moves up and down, thereby driving the connected collecting plate 33 to swing up and down around the hinge point. The collecting plate 33 can be reset by the spring 38. The impeller 5 drives one end of the collecting plate 33 to swing up and down, so that the debris can slide more smoothly into the replacement box 32, which is convenient for centralized collection of the debris, thereby better improving the drainage effect and preventing the debris from forming blockage when the rain is too heavy or it is used for a long time, causing water accumulation inside the tunnel, thereby seeping into the tunnel and affecting the internal structure and traffic safety of the tunnel.

[0049] In this embodiment, the impeller 5 has four blades. In other embodiments, the number of blades can be set according to actual conditions, such as Figure 6 As shown, a plurality of filter holes 37 are provided at the bottom of the replacement box 32, the bottom of the collection box 31 and the collection plate 33 to facilitate separation of water and impurities.

[0050] like Figure 8 As shown, in order to prevent the filter holes 37 on the collecting plate 33 from being blocked, an anti-blocking component is provided in this embodiment. The anti-blocking component includes a bottom plate 39 and a plurality of plug rods 310. The bottom plate 39 is fixed on the same side wall as the collecting box 31 in the water delivery trough 21, and is located below the plurality of filter holes 37 on the collecting plate 33. When the collecting plate 33 moves downward to its maximum limit, it is parallel to the bottom plate 39. A plurality of plug rods 310 are fixed to the upper end surface of the bottom plate 39. The plug rods 310 are arranged corresponding to the filter holes 37 on the collecting plate 33. The height of the plug rods 310 is greater than the distance between the collecting plate 33 and the bottom plate 39 when they are parallel, so that when the collecting plate 33 moves downward to its maximum limit, the plug rods 310 can be inserted into the filter holes 37. When the collecting plate 33 moves downward to its maximum limit, the plug rods 310 are correspondingly inserted into the filter holes 37 to push out the debris in the filter holes 37, thereby preventing the filter holes 37 from being blocked by debris.

[0051] The diameter of the filter port on the filter plate 4 is consistent with the diameter of the filter hole 37 , and the diameters of the filter port on the filter plate 4 and the filter hole 37 are smaller than the diameter of the water inlet hole 25 .

[0052] Embodiment 2:

[0053] According to the local precipitation conditions, the filter hole 37 on the collecting plate 33 is opened near the end of the collecting box 31, and the bottom plate 39 is set at a corresponding position. The insertion rod 310 on the bottom plate 39 is set corresponding to the filter hole 37. At this time, the length of the bottom plate 39 can be shortened, thereby saving consumables.

[0054] The rest of the working process and principles are consistent with those of Example 1.

[0055] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
