[0003] The "A biogas monitoring device" with publication number CN216051595U, in which the fermented biogas is just close to the liquid surface in the early stage of fermentation, and the biogas concentration detector is usually installed on the top or upper end of the biogas tank, so that the biogas concentration detector cannot detect the concentration of the biogas, and thus cannot monitor the biogas. At the same time, it is also unable to detect whether there is a biogas leakage problem. If the biogas leakage cannot be promptly alarmed, it is easy to cause a fire or even an explosion. Therefore, it is urgently necessary to design a gas leakage monitoring alarm device. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a device for monitoring and alarming gas leakage in a biogas tank, comprising a tank body, a mounting seat fixedly connected to the top of the tank body, a gas detector detachably connected to the top side wall of the mounting seat by screws, a receiving seat fixedly connected to one side wall of the tank body, a driving box fixedly connected to the top side wall of the receiving seat, a switch fixedly connected to the driving box near the top side wall of the tank body, a movable rod is provided in the middle of the driving box, a docking plate is fixedly connected to the side wall at one end of the movable rod, and a touch block is fixedly connected to the side wall on one side of the docking plate and opposite to the switch.

[0005] As a technical solution of the utility model, the side walls on both sides of the docking plate that are away from each other are fixedly connected with springs, the top outer wall of the driving box is detachably connected with an alarm by screws, and the alarm is connected to a switch by wires, and two limit rods are fixedly connected to the side walls in the driving box and away from the tank body, and a movable groove is opened in the movable rod and at a position relative to the limit rod, one end of the limit rod is inserted in the movable groove and can be telescopically moved in the movable groove, and a telescopic limiting rod is sleeved in the middle of the spring.

[0006] The movable rod can be driven by the spring, thereby driving the corresponding docking plate to move, and the alarm is triggered by the contact between the touch block and the switch, thereby reminding the staff of the leakage.

[0007] As a technical solution of the utility model, one end of the movable rod extends to the interior of the tank body, and a fixed column is fixedly connected to the side wall inside the tank body and close to the driving box. A telescopic column is telescopically connected inside the fixed column, and an end of the telescopic column away from the fixed column is fixedly connected to a force-bearing plate. Both the fixed column and the telescopic column are hollow cylindrical structures, and one end of the movable rod located in the tank body passes through the fixed column and the telescopic column, and is fixedly connected to the middle of the side wall on one side of the force-bearing plate, and the side wall of the telescopic column away from the telescopic column is established into a concave arc structure.

[0008] By setting up fixed columns and telescopic columns, the movable rod can be surrounded without affecting the extension and retraction of the movable rod, thereby preventing biogas from leaking from the connection between the movable rod and the side wall of the tank body.

[0009] The utility model has the following advantages: through the set spring and the force-bearing plate, the docking plate and the movable rod can be driven to move when the air pressure inside the tank body is reduced. When the air pressure drops to a specified numerical range, the switch is squeezed after the touch block to turn on the alarm, and an alarm is sounded through the alarm to remind the staff of the biogas leakage, so that the staff can deal with it in time to avoid safety accidents.

DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-3The utility model discloses a device for monitoring and alarming gas leakage in a biogas tank, comprising a tank body 1, a mounting seat 2 is fixedly connected to the top of the tank body 1, a gas detector 3 is detachably connected to the side wall of the top of the mounting seat 2 by screws, a receiving seat 4 is fixedly connected to one side wall of the tank body 1, a driving box 5 is fixedly connected to the top side wall of the receiving seat 4, a switch 12 is fixedly connected to the driving box 5 near the top side wall of the tank body 1, a movable rod 7 is set in the middle of the driving box 5, a docking plate 10 is fixedly connected to the side wall at one end of the movable rod 7, and a touch block 11 is fixedly connected to one side of the docking plate 10 and on the side wall opposite to the switch 12.

[0016] The gas detector 3 is set up to monitor the external environment gas around the tank body 1, so as to determine whether the environment around the tank body 1 contains biogas. If biogas is contained, it means that a leakage has occurred.

[0017] The side walls of the docking plate 10 that are away from each other are fixedly connected with springs 9, and two limit rods 8 are fixedly connected to the side walls in the driving box 5 and away from the tank body 1. A movable groove is provided in the movable rod 7 and at a position relative to the limit rod 8. One end of the limit rod 8 is inserted in the movable groove and can be telescopically moved in the movable groove, and a telescopic limiting rod is sleeved in the middle of the spring 9.

[0018] The two limit rods 8 inserted into the movable rod 7 can effectively limit the movable rod 7, ensuring that the movable rod 7 can move stably in the horizontal direction along the limit rods 8. The spring 9 can drive the movable rod 7 and the docking plate 10 to move smoothly, thereby driving the touch block 11 to apply pressure to the switch 12, thereby realizing the activation of the alarm 6.

[0019] One end of the movable rod 7 extends to the interior of the tank body 1, and a fixed column 13 is fixedly connected to the side wall inside the tank body 1 and close to the drive box 5. A telescopic column 15 is telescopically and movably connected inside the fixed column 13, and an end of the telescopic column 15 away from the fixed column 13 is fixedly connected to a force-bearing plate 14. The fixed column 13 and the telescopic column 15 are both hollow cylindrical structures. One end of the movable rod 7 located in the tank body 1 passes through the fixed column 13 and the telescopic column 15, and is fixedly connected to the middle of the side wall on one side of the force-bearing plate 14, and the side wall on the side of the telescopic column 15 away from the telescopic column 15 is established into a concave arc structure.

[0020] Because the fixed column 13 is fixed on the inner wall of the tank body 1, and the telescopic column 15 is telescopically connected in the fixed column 13, and a rubber ring is set between the telescopic column 15 and the fixed column 13, the movable rod 7 can be surrounded by the telescopic column 15 and the fixed column 13, so as to avoid biogas leakage from the connection point between the movable rod 7 and the tank body 1, thereby increasing the reliability of equipment operation.

[0021] When the air pressure inside the tank body 1 decreases, the squeezing force on the force plate 14 will become smaller, and the spring 9 can push the movable rod 7 to move toward the inside of the tank body 1. Since there is a certain distance between the docking plate 10 and the switch 12, if it is artificial deflation, the activity range of the docking plate 10 is within the established spacing interval, so that the touch block 11 will not touch the switch 12; but when the leakage problem is not artificial deflation, the docking plate 10 is easy to exceed the safe activity distance. At this time, the touch block 11 will contact the switch 12 and apply pressure to the switch 12, and the switch 12 is turned on and transmitted to the alarm 6 through the wire. The alarm 6 will alert the staff, and the gas detector 3 will detect the content of methane in the air around the tank body 1. Through the cooperation of the two, the accuracy of leakage detection can be increased.

[0022] Through the above technical solution, leakage alarm can be effectively and timely carried out to avoid safety accidents caused by biogas leakage due to failure to deal with it in time.

[0023] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0024] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
