Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of detection devices, and particularly relates to an automatic detection integrated device for rain and sewage mixing. BACKGROUND

[0002] With the development of economy and the deepening of urbanization, the urban population is rising sharply, and the sewage discharge of cities is increasing. The city is facing the demand of economic development on urban infrastructure, water quality type water shortage caused by water pollution, and the decline of urban residents' quality of life. In particular, the problem of rain and sewage mixing causes a large amount of rainwater to enter the sewage system during rain, so that the sewage pumping station and sewage plant cannot receive and process it and discharge it to the river, causing the water quality of the river to deteriorate. For newly built and reconstructed drainage networks, there are phenomena of incorrect connection of sewage pipes and rainwater pipes, which causes rainwater to enter the sewage pipe, and the sewage pumping station cannot accept excessive water during the rainfall period, and the sewage enters the water body through the overflow port, causing water pollution and damaging the ecological environment of the city. Water pollution even causes temporary black and odorous water, causing the river to be difficult to cure for a long time, and even harming the newly built water ecology in the river treatment. Therefore, obtaining the rain and sewage mixing of the pipe provides the basis for the current reconstruction.

[0003] The common method for checking rain and sewage pipe mixing in the drainage network is manual checking, but manual checking is extremely labor-intensive, and there are toxic gases in the pipe, which can easily damage the health of the workers. Therefore, in order to protect the safety of the workers, the existing rain and sewage pipe mixing is checked by using a liquid level meter. Specifically, the liquid level meter includes a host device and an antenna. The host device is arranged on the wall of a preset inspection well, and the host device is fixed on the wall by bolts or expansion bolts. Finally, the antenna and the host device are connected, so that the data measured by the host device is transmitted to the display terminal outside, and the detected data is displayed through the display terminal, so as to determine whether there is rain and sewage mixing in the preset inspection well.

[0004] However, the host device is installed by the expansion bolt fixing method, which is not convenient for regular inspection and maintenance of the host device. For example, after the host device is used for a long time, its performance and data transmission need to be checked. However, due to the installation method of the host device, it is not convenient for the maintenance personnel to disassemble and assemble it, so that only part of the components can be checked, and there is a certain performance risk in the later use. In addition, the host device is not easy to replace. SUMMARY

[0005] Therefore, the purpose of the present application is to provide an automatic detection integrated device for rain and sewage mixing, so as to solve the problem of the host device being installed by the expansion bolt fixing method, which is not convenient for regular inspection and maintenance of the host device.

[0006] The present invention proposes an integrated automatic detection device for mixed rainwater and sewage, which is installed on the well wall. The integrated device includes a mounting box for accommodating the detection equipment, and the mounting box is provided with a transmission mechanism and a fixing mechanism.

[0007] The mounting box includes a first box body and a second box body opposite to the first box body. The transmission mechanism is located between the first box body and the second box body. The first box body is provided with a first air chamber and a second air chamber for containing driving gas, and the first air chamber communicates with the second air chamber on the side away from the second box body.

[0008] When the first box and the second box approach each other, the transmission mechanism causes a driving gas to form inside the first box. The driving gas flows through the first air chamber to the second air chamber, thereby driving the fixing mechanism to move toward the second box and connect the first box and the second box.

[0009] Furthermore, the integrated device also includes an adjustment mechanism, which is disposed on the first housing and communicates with the first or second air chamber to adjust the total amount of the driving gas in the first and second air chambers.

[0010] Furthermore, the integrated device also includes an enclosure mechanism, which includes an expansion member connected between the first box and the second box.

[0011] When the first box and the second box are connected by the fixing mechanism, the expansion member contacts the side wall of the detection device.

[0012] Furthermore, the sidewall of the expansion member surrounds and connects to the inner wall of the first box and the inner wall of the second box;

[0013] When the first housing is away from the second housing, at least a portion of the expansion member is located outside the first housing and the second housing, so that an opening is formed on the expansion member for the detection device to extend into.

[0014] Furthermore, the enclosure mechanism includes a first drive rod, a first piston, and a third air chamber disposed within the first housing. One end of the first drive rod is connected to the second housing, and the other end extends into the third air chamber and is connected to the first piston. The first piston is slidably connected within the third air chamber.

[0015] The first housing has a through hole for connecting the third air chamber and the expansion member. When the second housing or the first housing moves toward the other, the second housing drives the first drive rod to move, so that the first piston injects expansion gas into the expansion member.

[0016] Furthermore, the transmission mechanism includes a second drive rod and a second piston.

[0017] One end of the second driving member is connected to the second housing, and the other end extends into the first air chamber and is connected to the second piston member. The second piston member is slidably connected in the first air chamber so that when the second housing or the first housing moves toward the other, the second driving rod drives the second piston member to move so as to form driving gas in the first air chamber.

[0018] Furthermore, the fixing mechanism includes a third drive rod, a fourth piston, a fixing member, and a mating member disposed on the second housing and cooperating with the fixing member;

[0019] One end of the third drive rod is connected to the fixing member, and the other end extends into the second air chamber and is connected to the fourth piston member. The fourth piston member is slidably connected in the second air chamber to drive the fixing member to move toward the mating member so that the fixing member and the mating member are connected.

[0020] Furthermore, the third drive rod is rotatably connected to the fourth piston member;

[0021] The third drive rod is provided with an adjustment part, which is used to drive the third drive rod to rotate when it moves.

[0022] The fastener is spirally arranged, and the mating part is provided with a spiral fixing hole that mates with the fastener.

[0023] Furthermore, the adjustment mechanism is located in the second air chamber. The adjustment mechanism includes an elastic element and an adjustment element having a first through hole and a second through hole. The adjustment element is connected to the second air chamber through the elastic element, and one end of the adjustment element can pass through the second air chamber and communicate with the outside.

[0024] When the total amount of driving gas in the first and second air chambers exceeds the elastic coefficient of the elastic element, the adjusting element causes one of the first or second through holes to extend out of the second air chamber, so that the other can transmit the driving gas to the outside.

[0025] When the total amount of the driving gas in the first air chamber and the second air chamber does not exceed the elastic coefficient of the elastic element, both the first through hole and the second through hole are located in the second air chamber.

[0026] Furthermore, the first box body is provided with a receiving space to accommodate the second box body.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] This device, through the arrangement of a mounting box, a transmission mechanism, and a fixing mechanism, enables the testing equipment to be installed inside the mounting box and fixed using the mounting box. Compared to the existing technology that uses expansion bolts to fix the testing equipment, this device utilizes the mounting box for pre-installation, which offers convenience in terms of periodic inspection and maintenance. Specifically, the mounting box includes a first box body and a second box body opposite to the first box body. The transmission mechanism is located between the first and second box bodies. The first box body has a first gas chamber and a second gas chamber for containing driving gas, and the first gas chamber is connected to the second gas chamber on the side away from the second box body. When the first and second box bodies approach each other, the transmission mechanism causes driving gas to form inside the first box body. The driving gas flows through the first gas chamber to the second gas chamber, thereby driving the fixing mechanism to move towards the second box body and connect the first and second box bodies.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Please see Figures 1 to 7 The image shows an integrated automatic detection device for rainwater and sewage mixing provided in an embodiment of the present invention, which is installed on the well wall.

[0043] The integrated device includes a mounting box 100 for accommodating the testing equipment. The mounting box 100 is provided with a transmission mechanism 200 and a fixing mechanism 300. The mounting box 100 includes a first box body 110 and a second box body 120 opposite to the first box body 110. The transmission mechanism 200 is located between the first box body 110 and the second box body 120. The first box body 110 is provided with a first gas chamber 400 and a second gas chamber 500 for accommodating driving gas. The first gas chamber 400 communicates with the second gas chamber 500 on the side away from the second box body 120. When the first box body 110 and the second box body 120 approach each other, the transmission mechanism 200 causes driving gas to form inside the first box body 110. The driving gas flows through the first gas chamber 400 to the second gas chamber 500, thereby driving the fixing mechanism 300 to move toward the second box body 120 to connect the first box body 110 and the second box body 120.

[0044] The transmission mechanism 200 includes a second drive rod 210 and a second piston 220. One end of the second drive rod is connected to the second housing 120, and the other end extends into the first air chamber 400 and is connected to the second piston 220. The second piston 220 is slidably connected within the first air chamber 400. When the second housing 120 or the first housing 110 moves toward the other, the second drive rod 210 drives the second piston 220 to move, thereby forming a driving gas within the first air chamber 400. This is not a limitation; the second drive rod 210 is specifically a columnar structure, and the second piston 220 is specifically made of a circular sealing gasket material with a certain thickness. Therefore, when the first air chamber 400 is in a sealed state, a driving gas is formed inside the first air chamber 400 when the second drive rod 210 pushes the second piston 220.

[0045] The fixing mechanism 300 includes a third drive rod 310, a fourth piston 320, a fixing member 330, and a mating member 340 disposed on the second housing 120 and cooperating with the fixing member 330. One end of the third drive rod 310 is connected to the fixing member 330, and the other end extends into the second air chamber 500 and is connected to the fourth piston 320. The fourth piston 320 is slidably connected in the second air chamber 500 to drive the fixing member 330 to move toward the mating member 340 so that the fixing member 330 and the mating member 340 are connected.

[0046] Specifically, the third drive rod 310 is rotatably connected to the fourth piston member 320. The third drive rod 310 is provided with an adjusting part 311, which is used to drive the third drive rod 310 to rotate during movement. The fixing member 330 is helically arranged, and the mating member 340 is provided with a helically fixed hole 341 that mates with the fixing member 330. In practice, the third drive rod 310 can be rotatably connected to the fourth piston member 320. Specifically, a bearing, as used in the prior art, is provided on the side wall of the fourth piston member 320. The third drive rod 310 is rotatably connected to the side wall of the fourth piston member 320 via the bearing. Furthermore, the adjusting part 311 specifically consists of an external thread on the third drive rod 310 and an internal thread on the inner wall of the second gas chamber 500. That is, when the fourth piston member 320 drives the third drive rod 310 to move due to the action of the driving gas, the adjusting part 311 is used to... The adjustment unit 311 enables the third drive rod 310 to rotate while moving. The rotation of the third drive rod 310 causes the fixing member 330 to rotate. Due to the spiral setting of the fixing member 330, and the matching fitting member 340 having a matching spiral fixing hole 341, the spiral of the fixing member 330 enters the fixing hole 341, thereby limiting the movement of the first box 110 and the second box 120 to ensure the overall stability of the detection equipment located in the mounting box 100.

[0047] In practice, to ensure that there is enough driving gas to drive the fixing mechanism 300 to connect the first box 110 and the second box 120, the integrated device also includes an adjustment mechanism 600. The adjustment mechanism 600 is disposed on the first box 110 and communicates with the first air chamber 400 or the second air chamber 500 to adjust the total amount of driving gas in the first air chamber 400 and the second air chamber 500.

[0048] Specifically, the adjusting mechanism 600 is located within the second air chamber 500. The adjusting mechanism 600 includes an elastic element 610 and an adjusting member 620 having a first through hole 621 and a second through hole 622. The adjusting member 620 is connected to the second air chamber 500 through the elastic element 610, and one end of the adjusting member 620 can pass through the second air chamber 500 to communicate with the outside. When the total amount of driving gas in the first air chamber 400 and the second air chamber 500 exceeds the elastic coefficient of the elastic element 610, the adjusting member 620 drives one of the first through holes 621 or the second through hole 622 to extend out of the second air chamber 500, so that the other can transmit the driving gas to the outside. When the total amount of driving gas in the first air chamber 400 and the second air chamber 500 does not exceed the elastic coefficient of the elastic element 610, both the first through hole 621 and the second through hole 622 are located within the second air chamber 500.

[0049] It should be noted that the driving gas is specifically the air present in the first air chamber 400 and the second air chamber 500. To prevent driving gas from still being transmitted towards the fixing mechanism 300 when the fixing member 330 is fully spiraled into the fixing hole 341, the excess driving gas will drive the adjusting member 620 to move. The driving gas is discharged from the first air chamber 400 and the second air chamber 500 through the first through hole 621 and the second through hole 622 on the adjusting member 620. Specifically, the first through hole 621 and the second through hole 622 are respectively set at both ends of the adjusting member 620. The elastic member 610 is specifically a spring. The outer wall of the adjusting member 620 is elastically connected to the second air chamber 500 through the elastic member 610. That is to say, when the driving gas drives the adjusting member 620 to move, the first through hole 621... 1. The first through hole 621 is connected to the second through hole 622 outside the second air chamber 500. When the first through hole 621 extends into the outside, the driving gas will pass through the second through hole 622 and exit through the first through hole 621 to realize the discharge of the driving gas. When the total amount of driving gas does not exceed the elastic coefficient of the elastic member 610, the adjusting member 620 moves into the interior of the second air chamber 500 through the elasticity of the elastic member 610, so that the first through hole 621 and the second through hole 622 are both located inside the second air chamber 500 to prevent the driving gas from flowing out. It should be noted that in this embodiment, when the first through hole 621 and the second through hole 622 are both located inside the second air chamber 500, the other side walls of the adjusting member 620 can be used to block the second air chamber 500 to avoid air leakage.

[0050] To ensure the stability of the testing equipment within the mounting box 100, the integrated device also includes a containment mechanism 700. The containment mechanism 700 includes an expansion member 710, which is connected between the first box 110 and the second box 120. When the first box 110 and the second box 120 are connected by the fixing mechanism 300, the expansion member 710 contacts the side wall of the testing equipment.

[0051] Specifically, the enclosure mechanism 700 includes a first drive rod 720, a first piston 730, and a third air chamber 740 disposed within the first housing 110. One end of the first drive rod 720 is connected to the second housing 120, and the other end extends into the third air chamber 740 and is connected to the first piston 730. The first piston 730 is slidably connected within the third air chamber 740. The first housing 110 is provided with a through hole 750 for connecting the third air chamber 740 and the expansion member 710. When the second housing 120 or the first housing 110 moves toward the other, the second housing 120 drives the first drive rod 720 to move, so that the first piston 730 injects expansion gas into the interior of the expansion member 710.

[0052] In practice, the expansion member 710 can be made of leather. That is, when the second box 120 or the first box 110 moves toward the other, the first drive rod 720 drives the first piston 730 to move, so as to form driving gas in the third gas chamber 740. Similarly, the driving gas enters the expansion member 710 through the through hole 750, so that the expansion member 710 expands to protect the side wall of the detection equipment.

[0053] Furthermore, the sidewalls of the expansion member 710 surround and connect to the inner walls of the first housing 110 and the second housing 120. When the first housing 110 is away from the second housing 120, at least a portion of the expansion member 710 is located outside the first housing 110 and the second housing 120, thus forming an opening on the expansion member 710 for the testing device to extend into. Specifically, the first housing 110 and the second housing 120 are specifically rectangular structures with internal hollowing out. The testing device is extended into the first housing 110 or the second housing 120 through the opening, and the expansion member 710 only limits and fixes the four sidewalls of the testing device to ensure the stability of the testing device within the mounting box 100. It should be noted that, in this embodiment, the bottom of the box is also provided with an opening for the testing end of the testing device to extend out. Please refer to [link to details]. Figure 1 As shown, two semi-circular openings are respectively provided at the inner bottom of the first box 110 and the second box 120.

[0054] In addition, the first box 110 is provided with a receiving space 111 for accommodating the second box 120. That is, when the second box 120 is moved toward the first box 110, the second box 120 will enter the interior of the first box 110 to save space inside the well.

[0055] Furthermore, it should be noted that in this embodiment, the back of the first housing 110 is provided with multiple mounting holes for installation with external expansion bolts, thereby ensuring that the mounting housing 100 is fixed to the external well wall. The detection device can be a radar level gauge, and can be installed in multiple wells to be detected, to achieve automatic and continuous measurement of water flow in corresponding nodes of the pipeline.

[0056] The following is a detailed description of the operation process of this invention in actual practice:

[0057] First, the first housing 110 is fixed to the well wall with the detection area using external expansion bolts. Then, the first housing 110 and the second housing 120 are separated. The detection device is manually inserted into either the first housing 110 or the second housing 120 through an opening. The second housing 120 is then pushed. During this pushing process, the second housing 120 simultaneously moves the first drive rod 720, the second drive rod 210, and the third drive rod 310. The first drive rod 720 causes the expansion member 710 to expand, thereby limiting and fixing the expansion member 710 to the four side walls of the detection device. The movement of the second drive rod 210 causes the first air chamber... Drive gas is generated inside 400, which drives the third drive rod 310 to move and rotate simultaneously. The spiral fastener 330 is inserted into the mating part 340 to fix the first box 110 and the second box 120. When the fastener 330 is fully spiraled into the fixing hole 341, drive gas is still transmitted to the fixing mechanism 300. At this time, the total amount of drive gas can be adjusted by setting the adjustment mechanism 600. It should be noted that the adjustment mechanism 600 can also be set on the expansion part 710 to ensure the reasonableness of the drive gas content. When the detection equipment needs to be repaired or replaced, the second box 120 can be pulled in the opposite direction.

[0058] Please see Figures 8 to 9 Here are the specific operational rules for determining whether rainwater and sewage are mixed:

[0059] To facilitate understanding of the following rules, the testing equipment includes an ultrasonic level gauge, a COD water quality sensor, and a terminal system; the testing modes include sunny weather mode and rainy weather mode.

[0060] When the detection equipment is placed in the rainwater well via an integrated device;

[0061] 1. Sunny Day Mode: When the ultrasonic level gauge detects that the water level in the rainwater well has risen to 30cm above the bottom of the pipe (i.e., h1+0.3m), the ultrasonic level gauge will transmit a signal to the COD water quality sensor, which will then perform online sampling and water quality analysis. The data results will be fed back to the terminal system, and the manager (operator) will determine the rainwater and sewage mixing situation according to relevant specifications.

[0062] 2. When the ultrasonic level gauge continuously monitors the rainwater well level for 15 minutes and finds that the level exceeds 30cm (h1+0.3m) above the bottom of the pipe, the terminal system will issue a command to enter the rainy weather mode, stop sampling and analysis, and shut down the COD water quality sensor.

[0063] 3. When the water level in the rainwater well drops to 30cm above the bottom of the pipe and no water level rise is detected after a 15-minute delay, the system enters the sunny weather mode. The terminal system then issues a command to re-sample and analyze the water according to the sunny weather rules.

[0064] When the testing equipment is placed in the sewage well via an integrated device;

[0065] 1. There is no difference between sunny and rainy season modes. When the ultrasonic level gauge monitors the water level in the sewage well and it rises to 30cm above the top of the pipe (i.e., h1+D2+0.3m), the ultrasonic level gauge transmits a signal to the COD water quality sensor, which performs online sampling and water quality analysis. The data results are fed back to the terminal system, and the manager (operator) determines the rainwater and sewage mixing situation according to relevant specifications.

[0066] 2. The above-mentioned time and elevation standards can be determined after subsequent adjustments.

[0067] 3. This sampling rule applies to areas that have undergone rainwater and sewage separation renovation and have complete rainwater and sewage systems.

[0068] In summary, the integrated automatic detection device for combined rainwater and sewage connections provided in the first embodiment of the present invention has at least the following advantages compared with the existing methods of fixing detection equipment:

[0069] In this device, the installation box 100, transmission mechanism 200, and fixing mechanism 300 are used to install the testing equipment inside the installation box 100 and fix the testing equipment. Compared with the existing technology that uses expansion bolts to fix the testing equipment, this device uses the installation box 100 to pre-install the testing equipment, which is more convenient for regular inspection and maintenance. Specifically, the installation box 100 includes a first box body 110 and a second box body 120 opposite to the first box body 110. The transmission mechanism 200 is located in the first box body. Between the first box 110 and the second box 120, the first box 110 is provided with a first air chamber 400 and a second air chamber 500 for containing driving gas. The first air chamber 400 is connected to the second air chamber 500 on the side away from the second box 120. When the first box 110 and the second box 120 approach each other, the driving gas is formed inside the first box 110 by the transmission mechanism 200. The driving gas flows through the first air chamber 400 to the second air chamber 500, so as to drive the fixing mechanism 300 to move toward the second box 120 to connect the first box 110 and the second box 120.
