Description

Technical Field

[0001] The present invention relates to a collection device, and more specifically, to a municipal sewage collection device. Background Technology

[0002] Water pollution refers to the pollution of water bodies (including lakes, rivers, oceans, aquifers, and groundwater). Sampling and monitoring wastewater are important means for understanding the state of water pollution.

[0003] When sampling wastewater, determining the sampling depth requires comprehensive consideration of factors such as the sampling purpose, water characteristics, and monitoring requirements. Generally, depending on the specific circumstances, surface, middle, bottom, or stratified sampling methods should be selected. Because water samples at different depths are situated in different environments, their water quality will inevitably vary significantly. Specifically: Sampling of surface water (0-0.5 meters) is suitable for monitoring changes in floating matter, oil, surfactants (such as detergents), and dissolved oxygen (DO) at the surface.

[0004] Sampling of the middle layer of water (0.5-1.5 meters) is commonly used for routine water quality monitoring. It can detect indicators such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), ammonia nitrogen, and total phosphorus, thereby reflecting the overall pollution status of the water body.

[0005] Sampling of bottom water (within 0.5 meters from the bottom) is mainly used to monitor sediment disturbance, heavy metal accumulation, or to detect anaerobic environmental indicators (such as sulfides, iron and manganese).

[0006] However, existing sampling equipment has certain limitations, typically only allowing for one water sample to be obtained after a single water immersion. If samples need to be collected from the same water source at different depths, multiple operations must be performed, which undoubtedly increases the complexity of the process. Summary of the Invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a municipal sewage collection device, comprising a suspension bracket 1, a lifting assembly 2, a lifting seat and a water intake assembly 3, wherein the suspension bracket 1 is installed on the hull of a ship. Multiple lifting seats are set up, and all of them are set on lifting components 2. Lifting components 2 are set on suspension brackets 1. Lifting components 2 are used to transport the lifting seats to move in sequence. When lifting components 2 control one lifting seat to move into position, lifting components 2 then control another lifting seat to move. Multiple water intake components 3 are provided, and each component is installed on a lifting base in a one-to-one manner. The water intake assembly 3 includes a water intake tank 31 and a sealing component 32. The water intake tank 31 is provided with a water inlet 311. The sealing component 32 is movably connected to the water inlet 311 and is used to seal the water intake tank 31. A limiting component is provided between the sealing component 32 and the suspension bracket 1. The limiting component is used to restrict the movement of the sealing component 32. Once the lifting seat is in position, the limiting component and the sealing component 32 separate.

[0022] The design of this invention controls the movement of the water collection component 3 through the lifting component 2, which can meet the collection operations at different depths and avoid the occurrence of the blocking component 32 being activated, thus ensuring the stability of the obtained sample water.

[0023] The present invention is further configured such that: the lifting seat includes a first lifting seat 4 and a second lifting seat 5, and the lifting assembly 2 includes a mounting frame 21, a lifting motor 22, a drive sprocket 23, an auxiliary sprocket 24, a first transmission sprocket 25, a second transmission sprocket 26, and a transmission chain 27; The first side of the first lifting seat 4 is slidably connected to the mounting frame 21, and the second lifting seat 5 is slidably connected to the second side of the second lifting seat 5; Both the drive sprocket 23 and the auxiliary sprocket 24 are mounted on the mounting bracket 21, and the drive sprocket 23 is connected to the lifting motor 22. The first transmission sprocket 25 is installed at the lower end of the first lifting seat 4, and the second transmission sprocket 26 is installed at the upper end of the first lifting seat 4. The drive chain 27 is connected in sequence to the drive sprocket 23, the first drive sprocket 25, the second drive sprocket 26 and the auxiliary sprocket 24; The transmission chain 27 is provided with a mounting plate 28 for mounting the second lifting seat 5. The mounting plate 28 is located between the second transmission sprocket 26 and the auxiliary sprocket 24, and the mounting plate 28 can make limited contact with the second transmission sprocket 26 during movement.

[0024] The invention is further configured such that: two sets of auxiliary sprockets 24 are provided, the mounting frame 21 is arranged in an L-shape, and the auxiliary sprockets 24 and the drive sprocket 23 are also arranged in an L-shape on the mounting frame 21; and one auxiliary sprocket 24 is vertically located below the second drive sprocket 26. The portion of the drive chain 27 located between the auxiliary sprocket 24 and the second drive sprocket 26 is denoted as chain A.

[0025] Taking two sets of water intake components 3 as an example, such as Figures 2 to 4 The figures show the three states of the first lifting seat 4 and the second lifting seat 5, respectively.

[0026] like Figure 2 As shown, when the first lifting seat 4 and the second lifting seat 5 are in the first state position: the two sets of water intake components 3 are in the retracted state. At this time, the overall length of the collection device is relatively short, which facilitates a series of operations such as transportation and disassembly.

[0027] like Figure 2 , Figure 3 As shown, when the second lifting seat 5 switches from the first state position to the second state position, the lifting motor 22 is started, causing the drive sprocket 23 to rotate. Under the action of the auxiliary sprocket 24, the first transmission sprocket 25, and the second transmission sprocket 26, the chain A moves upward. At this time, the second lifting seat 5 moves upward under the action of the mounting plate 28 (actually, the second lifting seat 5 moves underwater, see attached image). Figure 2 (The upward direction in the diagram is the downward direction in the actual process) until the mounting plate 28 abuts against the second transmission sprocket 26. At this point, a water sampling component 3 completes the first displacement movement. Assuming the movement stroke of the chain A is 1 meter, the water sampling component 3 descends by 1 meter. Then, based on the position of the water inlet, a sample water can be collected at the corresponding position. The position of the first water sampling depth can be changed simply by changing the distance between the second transmission sprocket 26 and the auxiliary sprocket 24.

[0028] like Figure 2 , Figure 3 , Figure 4As shown, when the first lifting seat 4 and the second lifting seat 5 switch from the second state position to the third state position, the lifting motor 22 continues to start. Because the second transmission sprocket 26 is jammed by the mounting plate 28, its rotation is restricted. At this time, the first transmission sprocket 25 switches from a fixed pulley state to a movable pulley state. Under the continued transmission of the lifting motor 22, the first lifting seat 4 slides upward, which in turn drives the second lifting seat 5 to move upward. If the travel distance of the second lifting seat 5 is 1.3 meters (the position difference between the two water intake components 3 is approximately 30 cm), then the second water intake component 3, after subtracting the position difference with the first water intake component 3, descends by 1 meter. The second water intake component 3 performs water intake operation at the 1-meter position, and the first water intake component 3 performs water intake operation at the 2.3-meter position. This situation is based on... Figure 1 The water intake components 3 are arranged vertically as shown.

[0029] In addition to Figure 1 As shown, in addition to being arranged vertically, the water intake components 3 can also be arranged at the same height or horizontally.

[0030] If the water intake components 3 are arranged in a left-right configuration and the two travel distances remain unchanged, then the water intake depth of the first water intake component 3 is 2.3 meters and the water intake depth of the second water intake component 3 is 1.3 meters.

[0031] Note that, Figures 2 to 4 This is a schematic diagram of the lifting assembly 2. The first lifting seat 4 and the second lifting seat 5 in the diagram are not complete. Therefore, lifting seats of corresponding sizes can be designed according to requirements to meet the installation requirements of the water intake assembly 3.

[0032] Furthermore, a rotation sensor is located at the position of the second transmission sprocket 26. When the mounting plate 28 moves into place, the second transmission sprocket 26 is restricted and cannot rotate. At this time, the data detected by the rotation sensor changes, thereby generating a sensing signal and transmitting it to the external controller. The controller stops the lifting motor 22. When a second lifting is required, the lifting motor 22 needs to be started again.

[0033] The present invention is further configured such that: the sealing component 32 includes a sealing seat 33, a sealing motor, a sealing rod 35, and a sealing plug 36. The sealing seat 33 is disposed at the water inlet 311, the sealing motor is installed inside the sealing seat 33, the sealing rod 35 is connected to the output end of the sealing motor, and the sealing plug 36 is installed at one end of the sealing rod 35. The sealing plug 36 is used to seal the water inlet 311.

[0034] The design of this structure controls the extension and retraction of the sealing rod 35 by starting the sealing motor, which works in conjunction with the sealing plug 36 to block the water inlet 311. When the sealing plug 36 moves down, it can effectively block the water inlet 311. When the sealing plug 36 moves up, it separates from the water inlet 311, thereby realizing the water intake operation.

[0035] The invention is further configured such that: an electric control board 41 is provided on both the first lifting seat 4 and the second lifting seat 5 extending upwards, the two electric control boards 41 are staggered, the limiting member is an electric control switch provided on the electric control board 41, the electric control switch is linked with the mounting bracket 21, when the lifting seat moves into position, the electric control switch on the lifting seat is triggered, and the sealing motor on the lifting seat can be remotely controlled.

[0036] The design of this structure uses the limiting component as an electric control switch. When the second lifting seat 5 moves into place, the electric control switch connected to the second lifting seat 5 is triggered (the triggering method can be pressing or popping, which only requires setting a protrusion or groove on the mounting bracket 21). At this time, the electric control switch generates an induction signal and sends it to the external controller, which can then control the corresponding sealing motor.

[0037] The present invention is further configured such that: a filter cover 37 is provided at the water inlet 311, and the filter cover 37 is provided with an opening through which the sealing rod 35 passes.

[0038] The present invention is further configured such that: a plurality of cleaning rods 361 are provided on the sealing plug 36, the cleaning rods 361 are arranged equidistantly around the sealing plug 36, the filter cover 37 is provided with a plurality of filter holes around its circumference, and the cleaning rods 361 are arranged in a one-to-one correspondence with the filter holes. When the sealing plug 36 moves upward, the cleaning rods 361 scrape the inner wall of the filter holes.

[0039] The design of the filter cover 37 can reduce the accumulation of upper impurities and floating objects at the inlet 311 during the downward movement of the water intake component 3, so that they can be sucked into the inlet 311 during the subsequent water intake process.

[0040] When impurities and floating objects accumulate at the filter holes, the upward movement of the plug 36 can move the impurities upward, preventing them from being sucked into the inlet 311.

[0041] The invention is further configured such that: the suspension bracket 1 includes a hanging arm 11 and an adjustment seat 12, the hanging arm 11 is arranged in an arc shape and is used to suspend to the side wall of the hull; the side wall can refer to the guardrail of the hull.

[0042] The adjusting seat 12 slides up and down and is connected to the lower end of the hanging arm 11; The lifting component 2 is mounted on the adjusting seat 12.

[0043] The present invention is further configured such that: a connecting plate 13 is provided in the middle of the hanging arm 11, and an adjusting bolt 14 is screwed onto the connecting plate 13; The adjusting seat 12 is rotatably connected to the adjusting bolt 14.

[0044] The design of this structure, such as Figure 1 As shown, since the draft of different collection vessels is affected by the weight of the hull, the distance between the water intake component 3 and the water surface is not constant when the boom is suspended on the hull. At this time, the vertical position of the adjusting seat 12 can be changed by rotating the adjusting bolt 14 to meet the relative position of the water intake component 3 and the water surface.

[0045] The following two positions can be adjusted as needed: 1. The bottom surface of the water tank 31 is as level as possible with the water surface. When the water inlet 311 is set on the upper surface of the water tank 31, the water sampling depth of the first water tank 31 is the travel distance of the chain A minus the height of the water tank 31.

[0046] 2. When the inlet 311 of the water tank 31 is as level as possible with the water surface, the water sampling depth of the first water tank is the travel distance of the chain A.

[0047] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
