Description

Technical Field

[0001] This utility model relates to the field of tunnel maintenance technology, and in particular to a tunnel venting and maintenance drainage structure. Background Technology

[0002] The tunnel venting, maintenance, and drainage structure is designed to ensure the safety and stability of the tunnel during operation. The drainage system is particularly important in cases of water accumulation, malfunctions, or when regular maintenance is required.

[0003] In the prior art, such as Chinese Patent No. CN206646466U, this utility model discloses a drainage structure for the emptying and maintenance of a water diversion tunnel. It includes a transverse support plate (2) located within the tunnel body (1), with several first drainage holes (3) on the support plate (2). A movable plate (10) fitted to the lower surface of the support plate (2) is provided, with several second drainage holes (11) on the movable plate (10). A longitudinal movable rod (12) is fixedly connected to one side of the lower surface of the movable plate (10), and a driving mechanism is connected to the other side. A first water pipe (13) is connected to the side wall of the tunnel body (1) below the movable plate (10). A drain valve is provided at one end of the first water pipe (13), and a second water pipe (15) is connected to one side of the drain valve. The driving mechanism and the drain valve are electrically connected to a controller (25). This utility model has the advantage of automatic drainage, solving the problem that water diversion tunnels require manual operation of water pumps for drainage.

[0004] While the above-mentioned solution has the advantage of automatic drainage, solving the problem of needing manual operation of water pumps for drainage in water diversion tunnels, the water inside the tunnel usually carries a large number of impurities when the tunnel is being emptied and drained. These impurities may originate from the tunnel construction process, groundwater leakage, or dirt accumulated during daily operation. Because the above-mentioned tunnel emptying and maintenance drainage structure lacks an effective water filtration system, it fails to adequately intercept and treat the impurities in the water during the drainage process. These impurities will then enter the drainage pipes with the water flow, and these foreign objects will accumulate in the pipes, causing blockages and affecting the normal operation of the drainage system. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology lacks an effective water filtration system, which fails to adequately intercept and treat impurities in the water during the drainage process. These impurities then enter the drainage pipe with the water flow, accumulate in the pipe, cause blockage, and thus affect the normal operation of the drainage system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel venting and maintenance drainage structure, comprising a tunnel body, a drainage channel provided on the left side of the tunnel body, a trash rack provided inside the drainage channel, a water inlet pipe fixedly installed at the bottom center of the drainage channel, a water storage tank provided at the bottom of the water inlet pipe, the water storage tank being located on the left side of the tunnel body, a diversion plate fixedly installed inside the water storage tank and at the bottom of the water inlet pipe, filter plates movably embedded on both sides of the inside of the water storage tank, the inner sides of the two filter plates being located outside the diversion plate, two return springs fixedly installed on the outer sides of the two filter plates, and the other ends of the two return springs being fixedly installed on the inner wall of the water storage tank.

[0007] In a preferred embodiment, both filter plates are provided with hinges at their bottoms, and a collection box is provided at the other end of the two hinges.

[0009] In a preferred embodiment, the collection box is fixedly embedded inside the water storage tank, and a spiral pusher is movably embedded inside the water storage tank, with the spiral pusher located inside the collection box.

[0010] The technical effect of adopting the above-mentioned further solution is that the impurities inside the collection box can be pushed away by the spiral pusher.

[0011] In a preferred embodiment, a first motor is fixedly installed on the front side of the spiral pusher bar, and the first motor is fixedly installed on the front side of the inside of the water storage tank. A storage box is provided on the rear side of the water storage tank.

[0012] The technical effect of adopting the above-mentioned further solution is that the first motor can drive the spiral pusher to rotate.

[0013] In a preferred embodiment, a pump is fixedly installed on the rear side of the water storage tank, and a water outlet pipe is fixedly installed on the rear side of the pump.

[0014] The technical effect of adopting the above-mentioned further solution is that water can be pumped out from inside the water storage tank.

[0019] In a preferred embodiment, pulleys are fixedly fitted on the outer surfaces of both rotating rods, and belt bodies are movably fitted on the outer surfaces of the two pulleys.

[0020] The technical effect of adopting the above-mentioned further solution is that the transmission can be achieved through the rotating rod to the pulley.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In use, this utility model, through the arrangement of the filter plate and the trash rack structure, not only effectively prevents larger impurities and garbage from entering the drainage system through the trash rack, reducing solid matter in the water, but also effectively collects fine impurities in the water into the collection box, preventing impurities from continuing to enter the water storage tank, reducing unnecessary burden in the subsequent storage and treatment process.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1, please refer to Figures 1 to 7This utility model provides a technical solution: a tunnel venting and maintenance drainage structure, including a tunnel body 1. A drainage channel 101 is provided on the left side inside the tunnel body 1. A trash rack 102 is provided inside the drainage channel 101. A water inlet pipe 103 is fixedly installed at the bottom center of the drainage channel 101. A water storage tank 104 is provided at the bottom of the water inlet pipe 103. The water storage tank 104 is located on the left side inside the tunnel body 1. A diversion plate 105 is fixedly installed inside the water storage tank 104 and at the bottom of the water inlet pipe 103. Filter plates 106 are movably embedded on both sides of the inside of the water storage tank 104. The inner sides of the two filter plates 106 are located outside the diversion plate 105. Two return springs 1 are fixedly installed on the outer sides of the two filter plates 106. 07. The other ends of the two return springs 107 are fixedly installed on the inner wall of the water storage tank 104. The bottom of the two filter plates 106 is provided with hinges 108. The other ends of the two hinges 108 are provided with collection boxes 109. The collection boxes 109 are fixedly embedded inside the water storage tank 104. The spiral pusher 110 is movably embedded inside the water storage tank 104. The spiral pusher 110 is located inside the collection box 109. The first motor 111 is fixedly installed on the front side of the spiral pusher 110. The first motor 111 is fixedly installed on the front side of the inside of the water storage tank 104. The storage box 112 is provided on the rear side of the water storage tank 104. The pump 113 is fixedly installed on the rear side of the water storage tank 104. The water outlet pipe 114 is fixedly installed on the rear side of the pump 113.

[0035] In this embodiment, personnel can first drain the water inside the tunnel body 1 into the drainage ditch 101 through the trash rack 102, and then transport the water through the drainage ditch 101 to enter the water storage tank 104 through the water inlet pipe 103 for collection and storage. The water entering the water storage tank 104 will be diverted by the diversion plate 105, causing the water to flow in two streams to the filter plates 106 on both sides. The water is filtered by the filter plates 106, so that impurities are retained on the outside of the filter plates 106 and roll down into the collection box 109 due to the inclined angle of the filter plates 106, while clean water flows into the water storage tank through the filter plates 106. Inside the tank 104, water is collected and stored. Meanwhile, personnel can start the pump 113 via its power supply system, allowing it to draw water from inside the storage tank 104 and transport it out of the pump 113 through the outlet pipe 114. The combination of the filter plate 106 and the trash rack 102 structure not only effectively prevents larger impurities and debris from entering the drainage system, reducing solid matter in the water, but also effectively gathers fine impurities in the water into the collection box 109, preventing them from entering the storage tank 104 and reducing unnecessary burdens in subsequent storage and processing.

[0036] Example 2, as Figures 1 to 7As shown, rotating rods 2 are movably embedded on both sides of the interior of the water storage tank 104. An eccentric wheel 202 is fixedly sleeved at the center of the outer surface of each of the two rotating rods 2. The two eccentric wheels 202 are movably connected to the outer side of the filter plate 106. A second motor 201 is fixedly installed on the rear side of one of the rotating rods 2. The second motor 201 is fixedly installed on the rear side of the interior of the water storage tank 104. A pulley 203 is fixedly sleeved on the outer surface of each of the two rotating rods 2. A belt body 204 is movably sleeved on the outer surface of each of the two pulleys 203.

[0037] In this embodiment, when the filter plate 106 filters water, the operator can start the second motor 201 via its power supply system. During operation, the second motor 201 drives the left rotating rod 2 via its output shaft. The left rotating rod 2, through the pulley 203 and belt body 204, drives the right rotating rod 2 to rotate. Simultaneously, the rotating rods 2 on both sides drive the eccentric wheel 202 to rotate in a circle. When the eccentric wheel 202 rotates inward, it pushes the filter plate 106 inward, causing it to flip inward via the hinge 108 and pulling the return spring 107. When the eccentric wheel 202 rotates outward, the return spring 107 resets, pulling the filter plate 106 inward. The outer side flips over, and the reciprocating circular rotation of the eccentric wheel 202 drives the filter plate 106 to flip back and forth, shaking off the impurities adhering to it. The impurities then roll down to the bottom of the collection box 109 at an angle. Simultaneously, the first motor 111 can be started by the power supply system of the first motor 111. During operation, the first motor drives the spiral pusher 110 to rotate via its output shaft. The spiral pusher 110 pushes the impurities forward, causing them to fall into the storage box 112 for collection and storage. The structure of the eccentric wheel 202 and the spiral pusher 110 not only automatically cleans the impurities adhering to the filter plate 106, avoiding the tedious process of manual cleaning, but also allows the spiral pusher 110 to push impurities into the storage box 112 for collection and storage, significantly improving the working efficiency of the filtration system.

[0038] Working principle: During use, personnel can first discharge water from inside the tunnel body 1 into the drainage ditch 101 through the trash rack 102. The water is then transported through the drainage ditch 101 and enters the water storage tank 104 through the inlet pipe 103 for collection and storage. The water entering the storage tank 104 is diverted by the diversion plate 105, causing it to flow in two streams towards the filter plates 106 on both sides. The water is filtered by the filter plates 106, retaining impurities on the outer side of the filter plates 106. Due to the inclined angle of the filter plates 106, impurities roll down into the collection box 109, while clean water flows into the collection box 109 through the filter plates 106. Inside the water storage tank 104, water is collected and stored. Meanwhile, personnel can start the pump 113 through the power supply system of the pump 113, so that when it is running, it can draw water out of the water storage tank 104 and transport it out of the pump 113 through the water outlet pipe 114. Through the structure of the filter plate 106 and the trash rack 102, not only can the trash rack 102 effectively prevent larger impurities and garbage from entering the drainage system, reducing solid matter in the water, but the design of the filter plate 106 can also effectively collect fine impurities in the water into the collection box 109, preventing impurities from continuing to enter the water storage tank 104, reducing unnecessary burden in the subsequent storage and treatment process. In use, when the filter plate 106 filters water, the operator can start the second motor 201 via its power supply system. During operation, the second motor 201 drives the left rotating rod 2 through its output shaft. The left rotating rod 2, via pulley 203 and belt body 204, drives the right rotating rod 2 to rotate. Simultaneously, the rotating rods 2 on both sides drive the eccentric wheel 202 to rotate in a circle. When the eccentric wheel 202 rotates inward, it pushes the filter plate 106 inward, causing it to flip inward via hinge 108 and pulling the return spring 107. When the eccentric wheel 202 rotates outward, the return spring 107 returns to its original position, pulling the filter plate 106 inward. The outer side flips over, and the reciprocating circular rotation of the eccentric wheel 202 drives the filter plate 106 to flip back and forth, shaking off the impurities adhering to it. The impurities then roll down to the bottom of the collection box 109 at an angle. Simultaneously, the first motor 111 can be started by the power supply system of the first motor 111. During operation, the first motor drives the spiral pusher 110 to rotate via its output shaft. The spiral pusher 110 pushes the impurities forward, causing them to fall into the storage box 112 for collection and storage. The structure of the eccentric wheel 202 and the spiral pusher 110 not only automatically cleans the impurities adhering to the filter plate 106, avoiding the tedious process of manual cleaning, but also allows the spiral pusher 110 to push impurities into the storage box 112 for collection and storage, significantly improving the working efficiency of the filtration system.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
