Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a compact, layered water intake tower that is easy to maintain. Background Technology

[0002] Traditional water intake methods often struggle to achieve precise water intake from different depths, limiting the depth of water resource management and water quality research. Currently, there are various types of stratified water intake towers in China, but most of them are quite wide due to the presence of numerous working gates along the horizontal direction and the loose installation of indoor equipment. Furthermore, the working gates use a single-leaf structure, which results in excessively large gate sizes to meet water intake requirements, complicated installation processes, and a high risk of safety accidents during installation. In addition, the debris-blocking structure in traditional water intake towers is also inadequate, failing to guarantee the quality of the water intake. Meanwhile, existing water intake towers lack diversion devices. When the gates are opened, a large amount of water rushes into the tower, generating turbulence and significant kinetic energy. The concrete in the tower is constantly eroded by water, posing a significant safety hazard. Although some systems now use pipe diversion, the pipes are limited by their size and cannot meet the water intake requirements of industrial and urban areas. If the pipe diameter is too large, it presents challenges in manufacturing, transportation, and, most importantly, installation requires multiple machines working together, which is costly and labor-intensive. Furthermore, pipe-shaped water intake towers are prone to corrosion at pipe joints and are inconvenient for maintenance.

[0003] Given the problems of traditional water intake towers, such as too many working gates arranged horizontally, loose equipment layout in the working chamber, excessively large working gates that are inconvenient to maintain, imperfect debris interception structure, and significant safety hazards, it is necessary to design a compact, stratified water intake tower that is easy to maintain to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a compact, stratified water intake tower that is convenient to maintain. This device not only solves the technical problems of existing water intake towers, such as too many working gates arranged horizontally, non-compact equipment arrangement in the working chamber, excessively large working gates that are inconvenient to maintain, imperfect debris-blocking structure, and significant safety hazards, but also achieves the function of convenient installation by replacing the emergency gate with a ball valve. In the event of an accident, the ball valve can be closed more quickly to avoid danger.

[0005] To achieve the aforementioned objective, the present invention adopts the following technical solution: a compact, layered water intake tower that is easy to maintain, comprising a control room, a working room, an annulus room, and a water intake treatment section.

[0006] The control room is equipped with opening and closing devices, including a sliding rod, a movable hook, and a control gate. The control gate can move up and down in the control gate slot and left and right in the control room via the movable hook and sliding rod. It can also be disassembled and removed for regular maintenance and cleaning.

[0007] The working chamber is divided into an upper water intake section, a middle water intake section, and a lower water intake section. An opening is made at the right end of the working chamber to balance the negative pressure generated by the water flow inside. The opening should be higher than the upstream water level. The working gates of the water intake sections are set in the same vertical direction. There are also control gate slots and maintenance doors. The control gate slots run from the bottom of the lower water intake tower to the bottom of the control room. The maintenance door is on the left side of the middle water intake section.

[0008] Because there is a lot of debris on the water surface, the upper intake section of the water tower is not equipped with a working gate. Water is only drawn from below the middle intake section. In addition, the bottom of the reservoir is severely silted up, and there is a lot of mud and sand in the water, which does not meet the water quality requirements. Therefore, the working gate of the lower intake section is set to start drawing water from above the half-story level. At the same time, a cavity half a story high is left below to store the backlog of water in the water tower.

[0009] A trash rack is installed at the front of the middle and lower water intake sections to block large debris in the deep water and ensure water quality. Behind the trash rack is a control gate slot. When the working gate of a certain water intake section is opened, closed, malfunctions, or undergoes routine maintenance, the control gate can reach that water intake section through the control gate slot to achieve emergency closure. This allows the louvered working gate to open and close in a waterless state, and also allows maintenance workers to safely enter the working gate for waterless operations. A louvered working gate is installed behind the control gate slot. Additionally, rounded overflow surfaces are installed behind the working gates of the middle and lower water intake sections. Water flows smoothly into the water treatment section through these rounded overflow surfaces.

[0010] The side room is equipped with a pedestrian staircase and a motor for opening and closing louvered working gates.

[0011] The bottom of the water intake treatment section is equipped with a steel plate, and a ball valve is also installed on the left side of the steel plate, on the same side as the side room. The steel plate can receive the water flowing out from above the water intake treatment section, reduce the scouring of the concrete at the bottom of the water intake tower by the high-altitude water flow, and allow it to smoothly enter the ball valve, and then guide the water out.

[0012] Preferably, the control gate slot extends directly from the bottom of the lower water intake section to the bottom of the control room. When the louvered working gate of a certain water intake section is opened or closed, malfunctions, or is under routine maintenance, the control gate can reach the water intake section through the control gate slot to block the water flow. This allows the louvered working gate to open and close in a waterless state, greatly reducing the opening and closing force, saving energy, and ensuring that maintenance workers can safely enter the working gate for waterless operations.

[0013] Preferably, an opening is provided on the right side of the working chamber to balance the negative pressure generated by the water flow into the working chamber and prevent damage to the water intake tower. Moreover, the opening should be higher than the upstream water level.

[0014] Preferably, the louvered working gate is divided into three separate small gates. Each small gate is opened and closed by a worm gear drive, that is, the motor drives the two worms at the top and bottom to rotate, thereby driving the worm wheel and the small gate to rotate. Moreover, it is easy to install and convenient to transport. Each small gate is a flat gate with grooves on both sides that can be embedded.

[0015] Preferably, the rounded overflow surface is located behind the middle and lower water intake sections, and an 8.8m space is left behind the overflow surface. According to calculations, the maximum horizontal displacement of the water flow behind the overflow surface is 8m; this can prevent the water flow from impacting the rear wall of the water intake tower.

[0016] Preferably, the motor and pedestrian stairs are located in the side room, which can ensure the dryness of the motor's working environment and facilitate the access of maintenance personnel.

[0017] Preferably, the inspection door is located on the left side of the middle water intake section, and maintenance personnel can easily enter the working room through the pedestrian stairs and the inspection door, thereby realizing daily inspection or emergency repair of the louvered working gate.

[0018] Preferably, the steel plate at the bottom of the water intake section is used to receive the water flowing out from above the water intake section, allowing it to smoothly enter the ball valve. At the same time, the steel plate can also reduce the erosion of the concrete at the bottom of the water intake tower by the high-altitude water flow, ensuring the safety of the water intake tower.

[0019] Preferably, the ball valve is located on the left side of the steel plate, which can stably discharge water. The ball valve replaces the emergency gate, realizing convenient installation. In the event of an accident, the ball valve can be closed more quickly to avoid danger. At the same time, maintenance personnel can also reach the ball valve through the pedestrian stairs to complete daily work.

[0020] Preferably, the control gate slot extends directly from the bottom of the lower water intake section to the bottom of the control room, the working gates are arranged in the same vertical direction, and the ball valve is located on the left side of the steel plate, on the same side as the side room, thus achieving a compact layout of the water intake tower equipment.

[0021] Preferably, since there are a lot of debris on the water surface, the upper water intake section of the water intake tower is not equipped with a working gate. Water is only taken from the middle water intake section. In addition, the bottom of the reservoir is severely silted up and there is a lot of mud and sand in the water, which does not meet the water quality requirements. Therefore, the working gate of the lower water intake section is set to start taking water from above half a floor. At the same time, a cavity half a floor high is left below to store the backlog of water in the water intake tower.

[0022] A compact, multi-tiered water intake tower for easy maintenance includes a vertically structured working chamber. The top of the working chamber is connected to a control room, and the side surface of the working chamber is connected to an auxiliary room. The interior of the working chamber is connected to a water treatment section. The control room is equipped with an opening and closing device, which includes a sliding rod spanning the inner wall of the control room. Multiple movable hooks are slidably connected to the lower surface of the sliding rod, and the movable hooks are hooked to the top of the control gate. The working chamber includes an upper water intake section, a middle water intake section, and a lower water intake section. An orifice is opened on the right side of the working chamber, and the orifice is higher than the upstream water level. The working chamber has a vertical control door slot that slides with the control gate. Multiple maintenance doors are vertically opened on one side surface of the working chamber. An auxiliary room is located on the left side of the working chamber, and a pedestrian staircase is installed inside the auxiliary room.

[0023] Preferably, a trash rack is provided on one side of the middle water intake section and the lower water intake section. The trash rack is adjacent to the control gate slot. Multiple louvered working gates are arranged vertically on the back side of the control gate slot. The side surface of the louvered working gates is arranged with rounded overflow surfaces to allow the water to flow smoothly into the water intake and treatment section.

[0024] Preferably, the louvered working gate includes three independent split gates, each split gate is opened and closed by a worm shaft drive, the worm shaft drive includes a motor and a worm connected to the output end of the motor; each split gate is a flat gate with grooves on both sides that can be embedded; the motor is located in the side room.

[0025] Preferably, the trash rack extends from the bottom of the lower water intake section to the bottom of the upper water intake section, the control door slot extends from the bottom of the lower water intake section to the bottom of the control room, the maintenance door is located on the left side of the middle water intake section, and the side room is connected behind the maintenance door.

[0026] Preferably, a gap is provided behind the rounded overflow surface arranged in the middle water intake section and the lower water intake section.

[0027] Preferably, a steel plate and a ball valve are provided at the bottom of the water intake treatment section.

[0028] Compared with the prior art, the beneficial effects of this utility model are reflected in:

[0029] 1. A control gate slot is set in the workshop to enable the working gate to open and close without water and to be inspected without water. When the working gate of a certain water intake section is opened and closed routinely, is under maintenance, or malfunctions, the control gate can be moved in front of the working gate of that layer through the control gate slot to block the water flow, so that the working gate can be opened and closed without water, which greatly reduces the opening and closing force and allows maintenance personnel to complete maintenance tasks without water.

[0030] The installation of louvered working gates in the water intake section realizes the concept of convenient installation and material saving in manufacturing.

[0031] 2. Setting up an ear chamber on the left side of the working chamber can ensure the dryness of the motor's working environment and also facilitate maintenance personnel to enter the working chamber and ball valve area.

[0032] 3. A rounded overflow surface is provided, with an 8.8m space behind the overflow surface for water diversion. This allows water to enter the water intake and treatment section stably without scouring the back wall of the water intake tower, thus ensuring the stability of the water intake tower.

[0033] 4. An opening is provided on the right side of the workshop to balance the negative pressure generated by water flow into the workshop and ensure the safety of the water tower.

[0034] 5. Installing steel plates at the bottom of the water intake section can reduce the impact of high-altitude water flow on the concrete at the bottom of the water intake tower, thereby ensuring the stability of the water intake tower.

[0035] 6. Installing ball valves in the water intake treatment section is more convenient than using emergency gate valves, and in the event of an accident, ball valves can be closed more quickly to avoid danger.

[0036] 7. The louvered working gates of the water intake section are set in the same vertical direction, and the ball valve is set on the left side of the working chamber, on the same side as the side room. The two achieve a compact layout of the water intake tower.

[0037] 8. Due to the large amount of debris on the water surface, no working gate is installed in the upper water intake section of the water intake tower. Water is only taken from the middle water intake section. In addition, the bottom of the reservoir is severely silted up, and there is a lot of mud and sand in the water, which does not meet the water quality requirements. Therefore, the working gate of the lower water intake section is set to start taking water from above the half-story level. At the same time, a cavity half a story high is left below to store the backlog of water in the water intake tower. Attached Figure Description

Detailed Implementation

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a compact, multi-level water intake tower that is easy to maintain, including a control room 1, a working chamber 2, an annex 3, and a water intake treatment section 4; the working chamber 2 further includes an upper water intake section 21, a middle water intake section 22, and a lower water intake section 23, and is equipped with a control door slot 26 and an inspection door 25. The louvered working gates 211 of the water intake sections are arranged in the same vertical direction. At the same time, an opening 24 is opened on the right side of the working chamber 2 to balance the negative pressure generated by the water flow into the working chamber 2, ensuring the safety of the water intake tower, and the opening 24 should be higher than the upstream water level.

[0047] The control room 1 is equipped with opening and closing devices, including a slide bar 11, a movable hook 12 and a control gate 13. The control gate 13 can be moved up and down in the control gate slot 26 and left and right in the control room 1 through the slide bar 11 and the movable hook 12. It can also be disassembled manually for convenient periodic maintenance and cleaning of debris.

[0048] The frontmost part of the workshop 2 is equipped with a debris barrier 27 and a control gate slot 26. The control gate slot 26 runs directly from the bottom of the lower water intake section 23 to the bottom of the control room 1, and the debris barrier 27 runs directly from the bottom of the lower water intake section 23 to the bottom of the upper water intake section 21 to block large debris in the deep water.

[0049] like Figure 2 and Figure 7 As shown, due to the large amount of debris on the water surface, the upper water intake section 21 is not equipped with a louvered working gate 211. Water is only drawn from below the middle water intake section 22. In addition, the bottom of the reservoir is severely silted up, and there is a lot of mud and sand in the water, which does not meet the water quality requirements for water intake. Therefore, the louvered working gate 211 of the lower water intake section 23 is set to draw water from above the half-layer. At the same time, a cavity half a layer high is left below to store the backwater volume in the water intake tower.

[0050] like Figure 5 , Figure 6 and Figure 7As shown, the louvered working gate 211 installed behind the control gate slot 26 of the middle water intake section 22 and the lower water intake section 23 is composed of three small gates. Each small gate is a flat gate with grooves on the left and right sides that can be embedded. The three small gates are opened and closed by worm shaft transmission. That is, the motor 31 causes the two worms 28 above and below the louvered working gate 211 to rotate, thereby driving the worm wheel 29 and the small gates to rotate.

[0051] The middle water intake section 22 and the lower water intake section 23 are also equipped with rounded overflow surfaces 212, and an 8.8m space is left behind the overflow surfaces to allow the water to flow down smoothly without impacting the rear wall of the water intake tower.

[0052] like Figure 7 As shown, during the operation of the device, the water flow from the middle water intake section 22 and the lower water intake section 23 passes through the trash rack 27, the control gate slot 26 and the louvered working gate 211, and smoothly enters the water treatment section 4 under the guidance of the rounded overflow surface 212.

[0053] During the operation of the device, when the louvered working gate 211 of a certain water intake section is opened and closed routinely, under maintenance, or malfunctions, the control gate 13 can reach the water intake section of that floor through the control gate slot 26 to block the water flow, thereby ensuring that the louvered working gate 211 can be opened and closed in a waterless state, greatly reducing the opening and closing force. Moreover, maintenance workers can safely enter the working gate through the pedestrian staircase 32 and maintenance door 25 in the side room 3 and complete routine maintenance or emergency repair tasks in a waterless state.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, a steel plate 41 is installed at the bottom of the water intake treatment section 4 to reduce the scouring of the concrete at the bottom of the water intake tower by the high-altitude water flow and ensure the stability of the water intake tower; the ball valve 42 is installed on the left side of the water intake treatment section 4, on the same side as the side room 3, which realizes the compactness of the water intake tower equipment layout in the design concept.

[0055] During the operation of the device, ball valve 42 can effectively control the water intake and flow rate. In the event that all working gates fail to close, ball valve 42 can close more quickly than emergency gates to ensure the safety of the water intake and avoid danger.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model. For example, the middle layer water intake section can be set in multiple layers according to actual needs.
