Description

Technical Field

[0001] The utility model relates to the technical field of sewer facilities, in particular to a sewer mosquito and rat prevention gate with an alarm function. Background Art

[0002] A sewer is an urban public facility, referring to the pipes for discharging sewage and rainwater from buildings; it also refers to the underground channels for discharging sewage and rainwater in cities, factories or villages. In the dark and humid environment of sewers, it is easy to breed mosquitoes, rats, etc., which pose a hazard to the living environment of residents. Therefore, in addition to using methods such as poisoning mosquitoes and rats with drugs, physical methods such as sewer mosquito and rat prevention gates can also be used to prevent mosquitoes, rats, etc. from coming out of the sewers.

[0003] When the existing sewer mosquito and rat prevention gates are in use, there is a situation where the gate does not close completely. For example, when there is a foreign object stuck at the gate, the gate cannot be completely closed. If not discovered in time, mosquitoes, rats, etc. in the sewer can come out through the gaps of the gate that is not completely closed. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a sewer mosquito and rat prevention gate with an alarm function.

[0005] To achieve the above purpose, the technical solution provided by the utility model is: a sewer mosquito and rat prevention gate with an alarm function, including a base clamped at the sewer opening, a flow guide plate and a flow guide funnel formed under the base, and a gate hinged between the flow guide plate and the flow guide funnel. An alarm is installed on the gate, and a gravity sensing module is arranged in the alarm. The alarm triggers the alarm state with the rotation of the gate to make the gravity sensing module act.

[0006] Preferably, the alarm includes a rear cover connected to the gate, a front cover covering the rear cover, and a gravity sensing module, a signal sending device, a power supply and a control circuit installed in the alarm. The gravity sensing module controls the signal sending device through the control circuit to send the triggered alarm state.

[0007] Preferably, the gravity sensing module includes a travel switch arranged in the alarm, a gravity ball contacting the travel switch, and a travel switch pressing platform for carrying the gravity ball. The gravity ball presses on or disengages from the travel switch on the travel switch pressing platform.

[0008] Further, the travel switch pressing platform is formed with a horizontal plane and a transition surface. The horizontal plane is arranged on one side where the gravity ball presses the trigger piece of the travel switch, and the transition surface is arranged on the side where the gravity ball disengages from the travel switch.

[0009] Furthermore, the transition surface and the horizontal surface form a step shape, so that the gravity ball is not easy to separate from the trigger pressing piece of the travel switch.

[0010] Furthermore, the transition surface is formed into an inclined shape, and the lowest end of the inclined transition surface faces the horizontal plane.

[0011] Furthermore, the lowest end of the inclined transition surface is at the same height as the highest end of the rebound of the trigger pressing piece of the travel switch.

[0012] Preferably, a groove is formed on the surface of the gate, the alarm is installed in the groove, and a blocking bar for fixing the alarm is provided at the opening of the groove.

[0013] Furthermore, one end of the blocking bar is hingedly fixed to one side of the groove of the gate, and the other end is latched to the other side of the groove of the gate.

[0014] Compared with the prior art, an alarm is installed on the gate, when a large amount of water flows into the sewer, the gate will be pushed to rotate, and the gravity sensing module in the alarm will send trigger information to the terminal after identification, including the triggering time and location; when the water has flowed out, the gate will automatically close if there is no foreign object stuck, and the gravity sensing module of the alarm will stop sending trigger information to the terminal after identification; when the alarm sends trigger information to the terminal for a long time, it can be judged whether there is a foreign object stuck in combination with the actual positioning situation, which can effectively prevent mosquitoes, rats, etc. from coming out of the sewer after the gate is stuck by foreign objects and leaves a gap.

[0026] The present utility model will be further described below in conjunction with specific embodiments: Embodiment 1

[0027] See the appendix Figures 1-3 As shown, a sewer mosquito and rat prevention gate with an alarm function includes a base 1 clamped at the sewer opening, a diversion plate 2 formed below the base 1, a diversion funnel 3, and a gate 4 hinged between the diversion plate 2 and the diversion funnel 3. An alarm 5 is installed on the gate 4, and a gravity sensing module 6 is arranged in the alarm 5. When the gate 4 rotates, the gravity sensing module 6 in the alarm 5 is triggered to the alarm state.

[0028] When a large amount of water flows into the sewer, it will push the gate 4 to rotate. After the gravity sensing module 6 in the alarm 5 recognizes it, it will send a triggered message to the terminal, including the triggering time and location. When the water has drained, the gate 4 will automatically close when there is no foreign object stuck. After the gravity sensing module 6 of the alarm 5 recognizes it, it will stop sending the triggered message to the terminal. When the alarm 5 sends the triggered message to the terminal for a long time, it can be judged whether there is a foreign object stuck in combination with the actual positioning situation, which can effectively prevent mosquitoes, rats, etc. from coming out of the sewer after the gate 4 is stuck by a foreign object and has a gap.

[0029] Specifically, the alarm 5 includes a rear cover 51 connected to the gate 4, a front cover 52 covering the rear cover 51, a waterproof ring 55 arranged between the rear cover 51 and the front cover 52, a gravity sensing module 6, a signal sending device, a power supply 54, and a control circuit 53 installed in the alarm 5. The gravity sensing module 6 controls the signal sending device to send the triggered alarm state through the control circuit 53. Embodiment 2

[0030] The difference from Embodiment 1 is that in this application, the gravity sensing module 6 includes a travel switch 61 disposed in the alarm 5, a gravity ball 62 in contact with the travel switch, and a travel switch pressing platform 63 for carrying the gravity ball 62. The gravity ball 62 presses on or disengages from the travel switch 61 on the travel switch pressing platform 63.

[0031] The travel switch pressing platform 63 is formed with a horizontal surface 631 and a transition surface 632. The horizontal surface 631 is disposed on one side where the gravity ball 62 presses on the trigger tab of the travel switch 61, and the transition surface 632 is disposed on the side where the gravity ball 62 disengages from the travel switch 61.

[0032] For example, the travel switch 61 is a normally closed switch. When the trigger tab of the travel switch 61 is triggered, the circuit is disconnected. When the gate 4 is in a state without water flow or no foreign object jamming, the gravity ball 62 will remain pressing on the trigger tab on the horizontal surface 631 of the travel switch pressing platform 63, and the travel switch 61 disconnects the circuit. When the gate 4 is in a state with water flow or foreign object jamming, the gravity ball 62 moves from the horizontal surface 631 to the transition surface 632 and disengages from the trigger tab of the travel switch 61, and the travel switch 61 conducts the circuit. Embodiment 3

[0033] The difference from Embodiment 2 is that the transition surface 632 and the horizontal surface 631 form a stepped shape, making it difficult for the gravity ball 62 to disengage from the trigger tab of the travel switch 61. Specifically, if the angle of the alarm 5 during installation causes the horizontal surface 631 to be horizontal or inclined towards the transition surface side (the angle of the water outlet during installation is different), the gravity ball 62 is likely to disengage from the horizontal surface 631 and reach the transition surface 632, causing the travel switch 61 to be wrongly triggered and alarmed. Therefore, by forming a stepped shape between the transition surface 632 and the horizontal surface 631, it can prevent the gravity ball 62 from disengaging from the horizontal surface 631 to the transition surface 632 to a certain extent when the gate 4 is closed. Embodiment 4

[0034] The difference from Embodiment 3 is that the transition surface 632 is formed in an inclined shape, and the lowest end of the inclined transition surface 632 faces the horizontal surface 631, which can play a better transition connection role compared to the transition surface 632 and the horizontal surface 631 forming a stepped shape.

[0035] The inclined transition surface 632 can not only prevent the gravity ball 62 from detaching from the horizontal surface 631 to the transition surface 632 when the gate 4 is closed, but also guide the gravity ball 62 to slowly return from the transition surface 632 to the horizontal surface 631 and press the travel switch 61 when the gate 4 returns from the open state to the closed state. This avoids the situation where, in certain specific cases, the gravity ball 62 cannot return from the step formed by the transition surface 632 and the horizontal surface 631 to the state of re-pressing the travel switch 61, resulting in the incorrect triggering of the alarm 5.

[0036] Furthermore, the lowest end of the inclined transition surface 632 is at the same height as the highest end of the trigger tab of the travel switch 61 after rebound, which can also form a step between the transition surface 632 and the horizontal surface 631, enabling the gravity ball 62 to accurately press the trigger tab of the travel switch 61 when returning from the transition surface 632 to the horizontal surface 631. Embodiment 5

[0037] The difference from Embodiment 1 is that a groove 41 is formed on the surface of the gate 4, the alarm 5 is installed in the groove 41, and a retaining strip 7 for fixing the alarm 5 is provided at the opening of the groove 41. The alarm 5 can be stably installed on the gate 4, and the gravity sensing module 6 of the alarm 5 is triggered to alarm as the gate 4 rotates; one end of the retaining strip 7 is hinged and fixed to one side of the groove 41 of the gate 4, and the other end is latched to the other side of the groove 41 of the gate 4, enabling the alarm 5 to be conveniently disassembled, replaced, and maintained.

[0038] Working principle:

[0039] When the gate 4 is normally closed, the gravity ball 62 in the alarm 5 is under the action of gravity on the horizontal surface 631 of the travel switch platen 63 and presses on the trigger tab of the travel switch 61, disconnecting the circuit of the travel switch 61. At this time, the alarm 5 does not trigger an alarm;

[0040] When a large amount of water flows into the sewer and pushes the gate 4 to rotate, the alarm 5 on the gate 4 rotates with the gate 4. The gravity ball 62 in the alarm 5 gradually moves from the horizontal surface 631 to the transition surface 632 with the rotation and simultaneously detaches from the travel switch 61, conducting the circuit of the travel switch 61. At this time, the alarm 5 triggers an alarm and sends the time and location to the terminal;

[0041] When a foreign object jams the gate 4, the process is the same as above. When the terminal processes it, it judges whether there is a situation of a foreign object jamming according to the actual local conditions, such as weather and other factors, and it is necessary to dispatch staff to go and check.
