Description

Technical Field

[0001] The utility model relates to the field of municipal engineering, in particular to a manhole cover base, a sewage manhole cover system and a sewage well. Background Art

[0002] The municipal sewage discharge system includes sewage wells and underground sewage pipes. The sewage pipes are connected to the sewage wells, and the sewage generated in the city flows in the underground sewage pipes.

[0003] A sewage manhole cover system is arranged on the sewage well. The sewage manhole cover system includes a manhole cover base and a manhole cover. The manhole cover base is installed at the wellhead of the sewage well, and the manhole cover is installed on the manhole cover base.

[0004] The sewage manhole cover system is an important facility on urban roads, which plays a role in closing the wellhead and can play a safety role. However, there are also some common problems, such as: 1. The manhole cover and the manhole cover base of the sewage manhole cover system are not locked together, and the manhole cover is easily stolen; 2. The sealing performance between the manhole cover and the manhole cover base of the sewage manhole cover system is not good, and there are ventilation holes on the manhole cover (the ventilation holes are used to discharge the gas in the sewage pipe to avoid excessive gas pressure in the sewage pipe). In this way, the odor in the sewage pipe is easy to emit from the wellhead, and the odor around the manhole cover is strong, affecting the surrounding environment; 3. Rainwater is easy to enter the sewage well from the ventilation holes and then enter the sewage pipe. On the one hand, this will increase the sewage treatment volume and cause the treatment cost to rise. On the other hand, since the rainwater enters the sewage pipe, some index detections of the sewage in the sewage pipe will be affected by the rainwater and there will be errors; 4. The stability of the manhole cover is poor and the vibration is large. When a vehicle passes by, the wheel rolls on the manhole cover, and a vibrating sound is generated between the manhole cover and the manhole cover base, affecting the rest of the surrounding residents; 5. The manhole cover is not easy to open and is relatively difficult to open; 6. Usually, it is impossible to know the flow operation of the sewage in the sewage well. Summary of the Utility Model

[0005] The utility model aims to provide a manhole cover base, a sewage manhole cover system and a sewage well to solve the problem that the manhole cover is not easy to open and is relatively difficult to open.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A manhole cover base includes a seat body. The seat body includes a cylindrical part, and the bottom end of the cylindrical part is used to extend into the sewage well; a vertical spring groove is provided on the seat body, and a spring for ejecting the manhole cover is placed in the spring groove; a fixing component for preventing the manhole cover from bouncing open is provided on the seat body.

[0007] The principle and advantages of this solution are as follows: In this solution, the spring groove on the seat body is used to accommodate the spring. When the manhole cover is closed on the manhole cover base, the manhole cover squeezes the spring, and the spring shrinks and deforms, storing energy. At the same time, through the fixing component, the manhole cover and the manhole cover base are fixed together, and the manhole cover will not bounce open under the elastic force of the spring. When it is necessary to open the manhole cover, operate or control the fixing component to release the fixation of the manhole cover. The manhole cover pops up upward under the elastic force of the spring, thus realizing the automatic opening of the manhole cover, solving the problem that the manhole cover is not easy to open and is laborious to open. The opening of the manhole cover is easier and more convenient.

[0008] In addition, the seat body in this solution includes a cylindrical part. When the manhole cover base is placed at the wellhead, the bottom end of the cylindrical part extends downward into the sewage well and is tightly attached to the inner wall of the well, which can strengthen the fixing effect of the manhole cover base, prevent the manhole cover base from shaking left and right at the wellhead, and thus is beneficial to improving the stability between the manhole cover base and the wellhead, reducing the noise generated by the shaking of the manhole cover base at the wellhead.

[0009] Preferably, as an improvement, the spring groove is located on the cylindrical part.

[0010] In this application, the spring groove is located on the cylindrical part because the vertical direction of the cylindrical part has a certain length. Setting the spring groove on the cylindrical part of the manhole cover base can ensure that the spring groove has a certain depth and avoid the depth of the spring groove being too shallow. The reason for setting the depth of the spring groove to be relatively large is that on the one hand, in order to ensure that the spring can smoothly bounce the manhole cover upward, the spring needs to have enough compression, and the length of the spring should not be too short. Therefore, the spring groove needs to have enough depth to accommodate the spring, and having enough depth of the spring groove can also ensure that the spring is stably located in the spring groove and avoid the spring being easily dropped from the spring groove.

[0011] Preferably, as an improvement, a spring placement part is fixedly provided on the inner wall of the cylindrical part, and the spring groove is located on the spring placement part.

[0012] Thus, the spring placement part is located on the inner wall of the cylindrical part, so that the spring extends out from the top of the spring placement part. When a sealing ring is set in the cover groove at the top of the cylindrical part, at this time the spring is located inside the sealing ring, and the top of the spring will not directly extend out from the cover groove, thus not affecting the setting of the sealing ring. The sealing ring can be completely set in a circle in the cover groove, which is beneficial to ensuring the sealing effect and shock absorption effect of the sealing ring.

[0013] Preferably, as an improvement, an anti-falling net is connected to the inner wall of the cylindrical part.

[0014] Preferably, as an improvement, a cover groove for placing the manhole cover is provided on the cylindrical part, and a sealing ring is provided on the cover groove.

[0015] Therefore, due to the setting of the sealing ring, since the sealing ring is made of a soft material, it can shock-absorb between the manhole cover and the manhole cover base, reduce the vibration sound generated between the manhole cover and the manhole cover base, and reduce the impact of noise on nearby residents, thus solving the problem of noise generation between the manhole cover and the manhole cover base to a certain extent. In addition, the setting of the sealing ring can also improve the sealing performance between the manhole cover and the manhole cover base, reduce the overflow of gas in the well from the gap between the manhole cover and the manhole cover base, reduce the peculiar smell around the manhole cover, and solve the problem of stench around the manhole cover to a certain extent.

[0016] Preferably, as an improvement, the fixing component is a lock hole, a card slot, an anti-theft lock unit or a clamping block. When the fixing component is a lock hole or a card slot, an anti-theft lock unit or a clamping block and other structures can be installed on the manhole cover at this time. The lock hole or the card slot is used for the lock pin or the clamping block of the anti-theft lock unit on the manhole cover to be inserted, so as to realize the fixation of the manhole cover and the manhole cover base, and the manhole cover will not be bounced up by the spring.

[0017] When the fixing component is an anti-theft lock unit or a clamping block, a corresponding lock hole or a card slot is provided on the manhole cover at this time. By inserting the lock pin or the clamping block of the anti-theft lock unit on the manhole cover base into the corresponding lock hole or card slot on the manhole cover, the fixation of the manhole cover and the manhole cover base is realized, and the manhole cover will not be bounced up by the spring.

[0018] In addition, the present utility model also adopts the following technical solution: a sewage manhole cover system, including a manhole cover, and also including any one of the above-mentioned manhole cover bases, and the manhole cover is installed on the manhole cover base.

[0019] Preferably, as an improvement, an anti-theft lock unit for locking the manhole cover and the manhole cover base together is provided on the manhole cover. The anti-theft lock unit includes a slidable lock pin, and the fixing component is a lock hole or a card slot.

[0020] Thus, by sliding the lock pin, it is controlled whether the lock pin is inserted into the lock hole or the card slot, so as to realize the unlocking or locking of the manhole cover and the manhole cover base.

[0021] Preferably, as an improvement, an exhaust gas discharge pipe is further included.

[0022] The exhaust gas discharge pipe is used to discharge the exhaust gas in the sewage well to the outside, realizing the function of exhaust gas pressure relief. In this way, there is no need to set ventilation holes on the manhole cover, the sealing performance of the manhole cover is better, and the problem of rainwater flowing into the sewage well through the ventilation holes of the manhole cover is avoided, and the influence of rainwater on the detection of some indexes of the sewage in the sewage pipe becomes smaller. And the exhaust gas in the sewage well will not be directly discharged to the outside from the manhole cover, the stench around the manhole cover becomes less, and the environment around the manhole cover becomes better. Thus, through this solution, the problem that the detection of some indexes of the sewage is affected by rainwater entering the sewage well is solved, and at the same time, the problems of strong stench and peculiar smell around the manhole cover are also solved.

[0023] Preferably, as an improvement, a deodorant is placed in the exhaust gas discharge pipe. Thus, the setting of the deodorant can deodorize the gas in the exhaust gas discharge pipe, reducing the odor of the gas discharged from the exhaust gas discharge pipe and minimizing the impact on the environment near the outlet end of the exhaust gas discharge pipe.

[0024] In addition, the present utility model also adopts the following technical solution: a sewage well, including a well body, with a well opening provided at the top of the well body, and further including the above-mentioned sewage manhole cover system, where the manhole cover and the manhole cover base are provided at the well opening; one end of the exhaust gas discharge pipe is inserted into the well body, and the other end of the exhaust gas discharge pipe is located outside the well body.

[0034] Embodiment 1

[0035] Basically as shown in the attached Figures 1-6 figures: This embodiment discloses a sewage manhole cover system, including a manhole cover 4 and a manhole cover base.

[0036] Combined with Figure 2 As shown, in this embodiment, a manhole cover base is disclosed, which includes a seat body. The seat body includes a cylindrical part 37 and an edge part 3. The cylindrical part 37 is cylindrical. Of course, in other embodiments, the cylindrical part 37 can also be of other shapes, such as square cylindrical. The edge part 3 is fixedly located around the cylindrical part 37. The edge part 3 in this embodiment is annular, and the fixing method between the edge part 3 and the cylindrical part 37 is welding or integrally formed fixing. A plurality of strip holes are provided on the edge part 3. The manhole cover base in this embodiment is made of cast iron material.

[0037] In this embodiment, the height of the cylindrical part 37 (the distance between the uppermost end and the lowermost end of the seat body) is 204 mm, the distance between the top surface of the edge part 3 and the top of the cylindrical part 37 (the uppermost end of the seat body) is 54 mm, and the distance between the bottom surface of the edge part 3 and the bottom end of the cylindrical part 37 (the lowermost end of the seat body) is 150 mm. Combined with Figure 3 As shown, the manhole cover base is arranged on the wellhead of the sewage well. The bottom end of the cylindrical part 37 extends into the sewage well, and the edge part 3 is located on the well body end 2 of the sewage well. The fixing method between the cylindrical part 37 and the inner wall of the well body end 2 can be bolt fixing, or by pouring concrete on the outer wall of the cylindrical part 37 for fixing through the concrete.

[0038] In this embodiment, the connection method between the manhole cover 4 and the manhole cover base is a rotational connection. Combined with Figure 4 As shown, a rotating block 41 is integrally formed or welded on the outer edge of the manhole cover 4. A horizontal rotating hole 42 is provided on the rotating block 41. Combined with Figure 2 As shown, a receiving part is integrally formed on the outer edge of the top of the cylindrical part 37. A receiving groove for receiving the rotating block 41 is provided on the receiving part. A connecting shaft 38 is connected to the receiving part. In this way, the manhole cover 4 is assembled on the manhole cover base, the rotating block 41 is located in the receiving part, and the connecting shaft 38 passes through the rotating hole 42 of the rotating block 41, thus realizing the rotational connection between the manhole cover 4 and the manhole cover base.

[0039] Combined with Figure 2 As shown, a vertical spring placement part 31 is integrally formed on the inner wall of the cylindrical part 37. The number of the spring placement parts 31 is two. The two spring placement parts 31 are located on both sides directly opposite to the connecting shaft 38. A vertical spring groove is provided on the spring placement part 31. A spring 32 for ejecting the manhole cover 4 is placed in the spring groove, and the top end of the spring 32 extends out from the top end of the spring groove. In this embodiment, the number of the spring placement parts 31 is two. In other embodiments, it can also be set to other numbers and distributed on the inner wall of the cylindrical part 37. In some embodiments, some pressing blocks can also be fixedly installed at the top end of the spring 32. In this way, when the manhole cover 4 covers the manhole cover base, the manhole cover 4 presses down on the pressing blocks, and the pressing blocks press down on the spring 32, so that the spring contracts and deforms to store energy.

[0040] Combined with Figure 2 As shown, the fixing component on the cylindrical part 37 Figure 2 The fixing component in is the keyhole 33, and the keyhole 33 is located opposite to the accommodating part. In other embodiments, the fixing component can also be a clamping groove.

[0041] For the manhole cover 4, combined with Figures 4-6 As shown, a theft-proof lock unit for locking the manhole cover 4 and the manhole cover base together is provided on the manhole cover 4. The theft-proof lock unit includes a fixing block 47 and a locking pin 48. The fixing block 47 is installed on the back of the manhole cover 4 by welding or by fixing means such as bolts and screws. Two support blocks 49 are welded or integrally fixed on the fixing block 47. The two support blocks 49 face each other. A pin hole is provided on the support block 49. The locking pin 48 slides horizontally in the pin hole. A through hole for the locking pin 48 to protrude is provided on the side wall of the edge of the manhole cover 4. Thus, when the manhole cover 4 is covered on the manhole cover base, the through hole on the side wall of the edge of the manhole cover 4 is opposite to the keyhole 33 on the manhole cover base. By sliding the locking pin 48, the locking pin 48 is inserted into the keyhole 33 of the manhole cover base, thereby realizing locking the manhole cover 4 and the manhole cover base together. By sliding the locking pin 48 out of the keyhole 33, the unlocking of the manhole cover 4 and the manhole cover base is realized.

[0042] Of course, there are various ways to control the horizontal sliding of the locking pin 48, and it can be controlled manually. For example Figure 6 As shown, a push block 46 is fixed to the left end of the locking pin 48. A compression spring (not shown in the figure, the left end of the compression spring is fixed to the manhole cover, and the right end of the compression spring is fixed to the push block 46, and the fixing method is a conventional method, such as welding or clamping) that gives a elastic force to the locking pin 48 to the right can be connected to the left side of the push block 46, or a tension spring (not shown in the figure, the two ends of the tension spring are respectively fixedly connected to the push block 46 and the left support block 49) is connected between the push block 46 and the left support block 49. The tension spring is sleeved on the locking pin 48. Usually, the locking pin 48 is inserted into the keyhole 33 under the action of the tension spring or the compression spring. When unlocking is required, the key 44 is inserted into the keyhole of the manhole cover 4. By turning the key 44, the key 44 pushes the push block 46 to move leftward. The push block 46 drives the locking pin 48 to move leftward against the elastic force of the compression spring or the tension spring, so that the locking pin 48 comes out of the keyhole 33, realizing unlocking. Combined with Figure 6 As shown, an inclined surface is provided at the right end of the locking pin 48. In this way, when the manhole cover 4 is covered on the manhole cover base, the inclined surface can make the locking pin 48 automatically retract, and the locking pin 48 will not interfere with the covering of the manhole cover 4 on the manhole cover base. When the locking pin 48 is opposite to the keyhole 33, the locking pin 48 is automatically inserted into the keyhole 33 under the action of the compression spring or the tension spring to lock the manhole cover 4 and the manhole cover base.

[0043] Combined with Figure 4As shown in the figure, when a keyhole is provided on the manhole cover 4, in order to prevent rainwater from flowing into the sewage well through the keyhole, a cover plate 43 is rotatably connected to the keyhole (the rotation method is realized by the cooperation of a shaft and a hole). In this way, when the lock is not opened usually, the cover plate 43 covers the keyhole, which can reduce the rainwater from entering the sewage well through the keyhole, and at the same time can also prevent the odor in the well from being emitted through the keyhole. When unlocking is required, the cover plate 43 is buckled open, and then the key 44 is inserted into the keyhole.

[0044] Of course, in other embodiments, an electric unlocking method can also be adopted. As shown in Figure 6 the figure, for example, an electromagnet is provided on the back of the manhole cover 4 to the left of the push block 46. When unlocking is required, the electromagnet is energized, and the electromagnet attracts the push block 46, so that the lock pin 48 moves to the left to achieve unlocking.

[0045] Of course, in some embodiments, the electric unlocking method and the manual unlocking method can be combined. In this way, when unlocking is required, unlocking can be achieved by the electromagnet attracting the push block 46 when energized, and unlocking can be achieved with the manual key 44 when de-energized.

[0046] Of course, in some embodiments, the anti-theft lock unit on the manhole cover 4 and the lock hole 33 on the manhole cover base can be interchanged. At this time, the fixing component on the manhole cover base is the anti-theft lock unit.

[0047] In addition, in some embodiments, the above anti-theft lock unit can be replaced with a simpler block structure. The block is inserted into the corresponding lock hole or card slot to fix the manhole cover and the manhole cover base, and the block is withdrawn from the lock hole or card slot to release the fixation between the manhole cover and the manhole cover base.

[0048] As shown in Figure 1 the figure, the sewage manhole cover 4 system of this embodiment is applied to a sewage well. The sewage well includes a well body 1. The top of the well body 1 is a well body end 2. The well body end 2 is provided with a wellhead, and the manhole cover base is arranged at the wellhead. In this solution, the bottom end of the cylindrical part 37 extends downward and tightly adheres to the inner wall of the well body end 2 of the sewage well. The cylindrical part 37 and the well body end 2 are horizontally limited, so as to strengthen the fixing effect of the manhole cover base, prevent the manhole cover base from shaking at the wellhead, and thus is beneficial to improving the stability between the manhole cover base and the wellhead, and reducing the noise generated by the shaking of the manhole cover base at the wellhead.

[0049] The cylindrical part 37 is provided with a cover groove for placing the manhole cover 4. Usually, the manhole cover 4 is closed in the cover groove of the manhole cover base, and the manhole cover 4 and the manhole cover base are locked together. The manhole cover 4 presses on the spring 32, and the spring 32 contracts and deforms, storing energy. When it is necessary to open the manhole cover 4, the manhole cover 4 and the manhole cover base are unlocked, and the manhole cover 4 pops up upward under the elastic force of the spring 32. One end of the manhole cover 4 away from the rotating block 41 tilts upward, thus realizing the automatic opening of the manhole cover 4, solving the problem that the manhole cover 4 is not easy to open and is more laborious to open, and making the opening of the manhole cover 4 easier and more convenient.

[0050] Embodiment 2

[0051] This embodiment provides another kind of manhole cover base. Combining Figure 2 As shown, an annular sealing ring groove is provided on the cover groove of the cylindrical part 37. A sealing ring 39 is placed in the sealing ring groove. The sealing ring 39 is stuck in the sealing ring groove, and the sealing ring 39 is made of rubber material.

[0052] Thus, due to the setting of the sealing ring 39, since the sealing ring 39 is made of a soft material, it can dampen the vibration between the manhole cover 4 and the manhole cover base, reduce the sound of vibration generated between the manhole cover 4 and the manhole cover base, and reduce the impact of noise on nearby residents. In addition, the setting of the sealing ring 39 can also improve the sealing performance between the manhole cover 4 and the manhole cover base, reduce the gas in the well from overflowing through the gap between the manhole cover 4 and the manhole cover base, and reduce the stench around the manhole cover, thus having a certain anti-odor function.

[0053] Embodiment 3

[0054] This embodiment further limits on the basis of Embodiment 1. Combining Figure 2 As shown, a plurality of connecting rings 34 are welded or integrally fixed to the inner wall of the cylindrical part 37. Hooks 35 are hung on the connecting rings 34, and a safety net 36 is hung on the hooks 35. The setting of the safety net 36 can improve the safety of the sewage manhole cover 4 system and reduce the risk of objects or people falling into the well.

[0055] Embodiment 4

[0056] Combining Figure 1 、 Figure 3 and Figure 7As shown, in this embodiment, the sewage manhole cover 4 system further includes an exhaust gas discharge pipe 5. A pipe hole 52 is provided on the side wall of the end 2 of the well body of the sewage well. The pipe hole 52 communicates with the inside of the sewage well. One end of the exhaust gas discharge pipe 5 communicates with the inside of the sewage well through the pipe hole 52, and the other end of the exhaust gas discharge pipe 5 is located outside the sewage well. The exhaust gas discharge pipe 5 in this embodiment is Z-shaped. After coming out of the sewage well, the exhaust gas discharge pipe 5 is first horizontally arranged as the first horizontal straight part, then vertically arranged upward as the vertical part 50, and then horizontally arranged as the second horizontal straight part. The extending length and height of the exhaust gas discharge pipe 5 can be adjusted according to actual situations.

[0057] The exhaust gas discharge pipe 5 is used to discharge the exhaust gas in the sewage well to the outside, realizing the function of exhaust gas pressure relief. In this way, there is no need to set ventilation holes on the manhole cover 4, avoiding the problem that rainwater flows into the sewage well through the ventilation holes of the manhole cover 4, and the detection of some indicators of the sewage in the sewage pipe is less affected by rainwater. Moreover, the exhaust gas in the sewage well will not be directly discharged to the outside from the manhole cover 4, and there is less odor around the manhole cover 4, and the environment around the manhole cover 4 is improved. In this solution, since the air outlet end of the second horizontal straight part of the exhaust gas discharge pipe 5 is horizontally arranged instead of vertically arranged, rainwater is not likely to enter the exhaust gas discharge pipe 5 either.

[0058] Combined with Figure 7 As shown, in other embodiments, a shielding cover 51 (such as clamped or threaded connection) is provided at the air outlet end of the exhaust gas discharge pipe 5, and the opening of the shielding cover 51 faces downward, which can further prevent rainwater from entering from the air outlet end of the exhaust gas discharge pipe 5.

[0059] In addition, in other embodiments, a filter cover (not shown in the figure) can also be covered at the air inlet end of the exhaust gas discharge pipe 5, and the filter cover can filter the substances entering the exhaust gas discharge pipe.

[0060] In addition, in other embodiments, a deodorant (the deodorant can be in the form of a deodorant package) can be installed at the air inlet end of the exhaust gas discharge pipe 5 or on the vertical part 50 outside the well. For installing the deodorant at the air inlet end of the exhaust gas discharge pipe 5, the deodorant package can be installed inside the filter cover. For installing the deodorant package on the top of the vertical part 50 of the exhaust gas discharge pipe 5, at this time, a bracket (the bracket is clamped inside the vertical part 50) is installed inside the vertical part 50 of the exhaust gas discharge pipe 5, and the deodorant package is placed on the bracket.

[0061] For the exhaust gas discharge pipe 5, it can be assembled on-site by splicing multiple pipes. The bent parts can be connected through elbows. For example, the vertical part 50 and the second horizontal straight part are threadedly connected through an elbow.

[0062] Embodiment 5

[0063] Combined with Figure 5As shown in the figure, in this embodiment, the manhole cover 4 is improved. An intelligent box 45 is connected to the back of the manhole cover 4, specifically located in the middle of the back of the manhole cover 4. Specifically, in terms of the connection method, a connecting piece is integrally fixed to the top of the intelligent box 45, and the connecting piece is connected to the back of the manhole cover 4 by means of screw connection. Some sensors can be placed in the intelligent box 45, such as a flow sensor, a liquid level sensor, and an exhaust gas detection sensor. A wire groove (not shown in the figure) is provided on the back of the manhole cover 4, and the wire groove is used to place the power line and the data line. The flow sensor, the liquid level sensor, and the exhaust gas detection sensor are respectively used to detect the flow rate, the liquid level, and the exhaust gas of the sewage. A microcontroller (such as Arduino, Raspberry Pi, etc., or a single-chip microcomputer) and a sending module (specifically a 4G or 5G wireless network sending module) are also provided in the intelligent box 45. These sensors are all electrically connected to the microcontroller, and the microcontroller reads the data of the sensors. The microcontroller is electrically connected to the sending module. In this way, the flow sensor, the liquid level sensor, and the exhaust gas detection sensor detect the relevant indicators of the sewage, and the detected indicators are transmitted to the microcontroller. The microcontroller transmits the data to the sending module, and the sending module sends the data to the server through wireless transmission of a 4G or 5G network. The staff can remotely access the server to understand the situation inside the sewage well.

[0064] In addition, in other embodiments, a positioning module is also provided in the intelligent box 45. For example, positioning is performed through GPS. The intelligent box 45 is built with a GPS chip that can receive signals from satellites, and the geographical location of the manhole cover 4 is determined by calculating the received signals, so as to play a certain role in positioning and anti-theft.

[0065] Embodiment 6

[0066] An odor detection sensor is installed inside the shielding cover (the installation method can be snap connection or fixed by screws). The odor detection sensor is a sensor used to detect and measure odors and malodorous gases in the air. The odor detection sensor is widely used in fields such as environmental monitoring, industrial emission control, sewage treatment plants, and garbage disposal stations. The odor detection sensor can specifically be an electrochemical sensor, a photoionization detector, a metal oxide semiconductor (MOS) sensor, or a catalytic combustion sensor.

[0067] A wire groove is axially provided on the pipe wall of the exhaust gas discharge pipe. A data line is connected to the odor detection sensor, and the data line is arranged in the wire groove of the exhaust gas discharge pipe. The other end of the data line is electrically connected to the microcontroller in the intelligent box.

[0068] In this way, the odor detection sensor detects the gas discharged from the exhaust pipe to check whether the discharged gas meets the standards. The detected data is transmitted to the microcontroller through the data line. The microcontroller transmits the signal to the sending module, and the sending module transmits it to the server through the 4G / 5G wireless network for the staff to remotely understand the quality of the discharged exhaust gas. When it is found that the gas quality detected by the odor detection sensor does not meet the standards, it indicates that the deodorizing effect of the deodorant has declined, and it is necessary to send someone to the site to replace the deodorant.

[0069] The above are only the embodiments of the present invention, and the common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like described in the specification can be used to interpret the content of the claims.
