It is an inalienable organic part of the building entity and the material basis and necessary condition for realizing the functions and values of the property. For example, fire-fighting equipment includes equipment such as fire water tanks, fire pumps, fire hydrants, and fire hoses.

[0003] At present, a Chinese patent with the publication number CN215182386U and the publication date of December 14, 2021 discloses an intelligent monitoring and alarm device for property equipment and facilities, which includes a box body. The interior of the box body is divided into an installation cavity and an adjustment cavity by a partition layer. Property equipment and facilities are installed inside the installation cavity. A heat insulation cavity door and a sealing cavity door are respectively hinged on one side of the installation cavity and one side of the adjustment cavity. A dehumidification component and a cooling component are respectively arranged inside the adjustment cavity. The dehumidification component includes a dehumidification box and a first circulation pump. The dehumidification box and the first circulation pump are both fixedly installed on one side of the bottom end of the inner wall of the adjustment cavity. Two partition nets are respectively fixedly arranged on both sides inside the dehumidification box. Absorbent silica gel particles are filled between the two partition nets. A temperature and humidity control switch is fixedly installed at the top end of the inner wall of the installation cavity. The probe of the temperature and humidity control switch is fixedly arranged inside the installation cavity. A vacuum heat insulation cavity is opened inside the wall of the installation cavity.

[0004] Among them, when fire-fighting equipment is stored in the box body, in the prior art, in order to ensure that the fire-fighting equipment can operate normally in case of emergencies, the water pressure and water flow in the fire hydrant need to be checked at regular intervals; however, when the operator checks the fire hydrant, the fire hydrant is often opened to drain water externally, which will cause waste of this part of water. Summary of the Invention

[0005] The purpose of the present invention is to provide a monitoring and protection system for property equipment and facilities, which can collect and reuse the water discharged during the inspection of the fire hydrant.

[0006] The above technical object of the present invention is achieved through the following technical solutions: A property equipment monitoring and protection system includes a box body, fire-fighting equipment stored in the box body, and a monitoring camera arranged on the upper side of the box body. The fire-fighting equipment includes fire extinguishers, fire hoses, and fire hydrants. A valve body and a turntable are arranged at the upper end of the fire hydrant. A detection end is arranged on one side of the fire hydrant. An electromagnetic valve is installed on the detection end. At one end of the detection end away from the fire hydrant, a detection pipe extending in the vertically upward direction is arranged. A pressure plate is arranged in the detection pipe. A water collection tank is arranged at the lower side of the box body. A drain pipe is arranged on the detection pipe, with its upper end communicating with the lower end inside the detection pipe and its lower end communicating with the inside of the water collection tank.

[0007] By adopting the above technical solutions, when it is necessary to check the water pressure and water flow smoothness of the fire hydrant, the electromagnetic valve is opened so that the detection end sprays water into the detection pipe. The sprayed water can drive the pressure plate to move upward in the detection pipe. The water pressure condition can be known through the upward movement height of the pressure plate. The water falling into the detection pipe can be discharged into the water collection tank along the drain pipe, and the water in the water collection tank can be used for daily use. Finally, the water discharged during the inspection of the fire hydrant can be collected and reused.

[0008] The further setting of the present invention is: A proximity sensor for detecting the position of the pressure plate after it moves upward under the push of water flow is arranged on the side wall at the upper end of the detection pipe. A controller electrically connected to the proximity sensor and the electromagnetic valve is arranged on the upper side of the box body. An alarm is arranged on the controller; when the controller controls the electromagnetic valve and the proximity sensor to be opened at regular intervals, when the proximity sensor does not detect the pressure plate moving up to the height of the proximity sensor, the controller controls the alarm to emit an alarm sound.

[0009] By adopting the above technical solutions, the controller controls the electromagnetic valve and the proximity sensor to be opened at regular intervals, so that the detection end sprays water into the detection pipe, and the sprayed water can drive the pressure plate to move upward in the detection pipe; when the pressure plate moves up to the position of the proximity sensor, it means the water pressure is normal, and the controller will not control the alarm to emit an alarm sound; while when the proximity sensor does not detect the pressure plate moving up to the height of the proximity sensor, it means there is no water flow or the water pressure is insufficient, and then the controller controls the alarm to emit an alarm sound to warn that the fire hydrant has a fault.

[0010] A further setting of the present invention is that a piston cylinder is arranged on the upper side of the box body. A piston block is embedded in the piston cylinder. A piston rod with one end connected to the piston block is arranged on the piston block. A connecting hose extending towards the side of the monitoring camera is arranged at one end of the piston cylinder close to the piston block. A nozzle for blowing the monitoring camera is arranged at one end of the connecting hose away from the piston cylinder. A bracket for supporting the nozzle is arranged on the box body. A linkage assembly for driving the piston block to move when the pressure plate moves is arranged on the box body.

[0011] By adopting the above technical solution, when the pressure plate moves, the piston block can be driven to move in the piston cylinder through the linkage assembly. The movement of the piston block can use the connecting hose and the nozzle to blow the monitoring camera, so as to realize cleaning the monitoring camera every once in a while and avoid the influence of dust on the surface of the monitoring camera on the shooting clarity.

[0012] A further setting of the present invention is that an opening part is formed at the position between the piston cylinder and the detection tube on the upper side of the box body. The linkage assembly includes a column extending vertically upward on the upper side of the pressure plate, a first guide wheel arranged on the side wall at the upper end of the detection tube, a second guide wheel arranged on the side wall of the box body at the position below the opening part, a third guide wheel arranged on the upper side of the box body and close to the piston cylinder side, a connecting rope with one end connected to the end of the piston rod away from the piston block and the other end passing through the first guide wheel, the second guide wheel and the third guide wheel and then connected to the column, and two reset springs arranged on both sides inside the piston cylinder with one end connected to the piston block and the other end connected to the inner wall of the piston cylinder.

[0013] By adopting the above technical solution, when the pressure plate moves upward under the impact of high-pressure water flow, the pressure plate can drive the column to move upward. Then the column can pull the piston rod through the connecting rope, so that the piston rod and the piston block move towards the side away from the connecting hose, and the reset spring is compressed. When the pressure plate loses the impact of water flow and moves downward, the reset spring can elastically recover. Then the reset spring can push the piston block towards the side close to the connecting hose, so as to press the air in the piston cylinder to the nozzle through the connecting hose. Then the air ejected from the nozzle can blow the monitoring camera.

[0014] A further setting of the present invention is that a connecting sleeve communicated with the inside of the piston cylinder and allowing the upper end of the column to pass through is arranged on the lower side of the piston cylinder. A water inlet channel extending vertically and penetrating the pressure plate is formed in the column. A water injection hole communicated with the upper end of the water inlet channel and used for injecting water into the piston cylinder is formed at the upper end of the column. A sealing assembly for connecting the water injection hole and the water inlet channel when the water injection hole moves up into the piston cylinder is arranged between the column and the piston cylinder.

[0015] By adopting the above technical solution, when the pressure plate drives the column to move upward, the upper end of the column can pass through the connecting sleeve and enter the piston cylinder. When the water injection hole at the upper end of the column moves upward into the piston cylinder, the water injection hole and the water inlet passage are connected by using the plugging assembly. At this time, the water flow in the detection pipe can move upward along the water inlet passage and spray out from the water injection hole, and this part of the water can enter the piston cylinder. When the return spring pushes the piston block to move toward the side close to the connecting hose, the water flow in the piston cylinder can spray out from the nozzle to clean the monitoring camera, so as to realize the efficient cleaning of the monitoring camera through the water in the detection pipe.

[0016] The further setting of the present invention is that: the piston cylinder extends obliquely downward toward the side of the connecting hose, and a connecting arm connected to the lower side of the piston cylinder is arranged on the upper side of the box body.

[0017] By adopting the above technical solution, by using the piston cylinder extending obliquely downward toward the side of the connecting hose, when the column moves downward and leaves the connecting sleeve, the inclined piston cylinder can retain a part of the water, avoiding all the water in the piston cylinder from flowing out of the connecting sleeve. At the same time, it also makes the piston cylinder have both air and water. When the return spring pushes the piston block to move toward the side close to the connecting hose, the water flow in the piston cylinder will first spray on the monitoring camera to wash the surface of the monitoring camera. When the water flow is used up, the air in the piston cylinder can be sprayed on the surface of the monitoring camera with water droplets, so as to blow away the water droplets on the surface of the monitoring camera by blowing, avoiding the water droplets from affecting the shooting effect of the monitoring camera.

[0018] The further setting of the present invention is that: a vertically drooping part is integrally arranged on the connecting hose.

[0019] By adopting the above technical solution, by using the vertically drooping part integrally arranged on the connecting hose, a part of the water can be accumulated in the drooping part, so as to ensure that there is sufficient water to be sprayed on the monitoring camera.

[0020] The further setting of the present invention is that: the plugging assembly includes a cavity part opened in the upper end of the water inlet passage, a conical plugging block arranged in the cavity part, a plugging spring with one end connected to the plugging block and the other end connected to the inner wall of the cavity part, a connecting hole opened in the upper end of the column and communicated with the water injection hole, a connecting rod with the lower end connected to the plugging block and the upper end passing through the connecting hole, a groove opened in the upper end surface of the column and located at the position of the connecting hole, a push plate arranged at the upper end of the connecting rod and located in the groove, a connecting cover arranged on the upper side of the piston cylinder for the upper end of the column to be embedded, and a striker arranged on the inner wall of the connecting cover and used for abutting against the push plate.

[0021] By adopting the above technical solution, when the water injection hole at the upper end of the column moves upward into the piston cylinder, the upper end of the column is embedded in the connecting cover. The striker in the connecting cover can then push the push plate downward, thereby driving the plug block in the cavity part to move downward through the connecting rod, and the plug spring is compressed. At this time, the water injection hole and the water inlet channel can be connected, and a part of the water flow in the water flow acting on the pressure plate can enter the water injection hole along the water inlet channel; when the upper end of the column is not embedded in the connecting cover, the plug spring can push the plug block to block the water inlet channel, thereby closing the water inlet channel and avoiding water waste caused by the water injection hole spraying water outward when the column is not in the piston cylinder.

[0022] The further setting of the present invention is: the column includes a first column body with the lower end connected to the pressure plate and a second column body with the lower end butt-jointed to the upper end of the first column body. The lower end of the second column body is provided with a threaded end, and the upper end of the first column body is provided with an internal threaded sleeve for threaded connection with the threaded end. A connecting ring is provided on the side wall of the second column body, a hook hooked on the connecting ring is provided at the end of the connecting rope, a prism is provided at the side of the turntable, and the water injection hole is an internal prism hole for cooperating with the prism.

[0023] By adopting the above technical solution, when it is necessary to rotate the turntable to open the valve body of the fire hydrant, by using the prism provided at the side of the turntable and the water injection hole being an internal prism hole for cooperating with the prism, the operator can unscrew the second column body from the first column body to disassemble the second column body from the first column body. At the same time, the hook of the connecting rope is taken off from the connecting ring. At this time, the water injection hole on the second column body can be provided for the prism to be embedded, and a lever arm for rotating the turntable can be formed through the second column body, and finally it is beneficial to conveniently rotate the turntable to realize the multiple utilization of the column.

[0024] The beneficial effect of the present invention is: the controller controls the solenoid valve and the proximity sensor to be turned on every once in a while, so that the detection end sprays water into the detection tube, and the sprayed high-pressure water can drive the pressure plate to move upward in the detection tube; when the pressure plate moves upward to the position of the proximity sensor, it means that the water pressure is normal, and the controller will not control the alarm to sound; when the proximity sensor does not detect the pressure plate moving upward to the height of the proximity sensor, it means that there is no water flow or the water pressure is insufficient. Subsequently, the controller controls the alarm to sound, thereby warning that the fire hydrant has a malfunction;

[0025] When the pressure plate moves upward under the impact of high-pressure water flow, the pressure plate can drive the column to move upward. Subsequently, the column can pull the piston rod through the connecting rope, causing the piston rod and the piston block to move away from the connecting hose side, and the return spring is compressed. At the same time, as the column moves upward, the upper end of the column can pass through the connecting sleeve and enter the piston cylinder. When the water injection hole at the upper end of the column moves upward into the piston cylinder, the upper end of the column can be embedded in the connecting cover. The striker in the connecting cover can push the push plate downward, thereby driving the blocking block in the cavity part to move downward through the connecting rod, and the blocking spring is compressed. At this time, the water injection hole and the water inlet channel can be connected, and a part of the water flow acting on the pressure plate can enter the water injection hole along the water inlet channel, and this part of the water can enter the piston cylinder.

[0026] When the pressure plate moves downward due to the loss of the impact of water flow, first, the upper end of the column leaves the connecting cover, and the blocking spring can push the blocking block to block the water inlet channel, thereby closing the water inlet channel to avoid water waste caused by water spraying out of the water injection hole. At the same time, the return spring can undergo elastic recovery, and then the return spring can push the piston block to move toward the side close to the connecting hose. The water flow in the piston cylinder can be sprayed out from the nozzle to clean the monitoring camera, thereby achieving efficient cleaning of the monitoring camera through the water in the detection tube. The piston cylinder extends obliquely downward toward the connecting hose side. When the column moves downward and leaves the connecting sleeve, the inclined piston cylinder can retain a part of the water to prevent all the water in the piston cylinder from flowing out of the connecting sleeve. At the same time, it also makes the piston cylinder contain both air and water. When the return spring pushes the piston block to move toward the side close to the connecting hose, the water flow in the piston cylinder will first be sprayed on the monitoring camera to wash the surface of the monitoring camera. When the water flow is exhausted, the air in the piston cylinder can be sprayed on the surface of the monitoring camera with water droplets, thereby blowing away the water droplets on the surface of the monitoring camera through blowing to avoid the influence of water droplets on the shooting effect of the monitoring camera.

[0027] At the same time, when it is necessary to rotate the turntable to open the valve body of the fire hydrant, using the prism provided on the side of the turntable and the water injection hole being an inner prism hole for cooperating with the prism, the operator can unscrew the second cylinder from the first cylinder to disassemble the second cylinder from the first cylinder. At the same time, remove the hook of the connecting rope from the connecting ring. At this time, the water injection hole on the second cylinder can be used for the prism to be embedded. A force arm for rotating the turntable can be formed through the second cylinder, and finally, it is beneficial to conveniently rotate the turntable to realize the multiple utilization of the column.

At the same time, the push plate 77 is integrally provided at the upper end of the connecting rod 75 and is located in the groove 76. The connection cover 78 is integrally provided on the upper side of the piston cylinder 5 for the upper end of the upright column 61 to be embedded.

[0041] Principle: The controller 12 controls the solenoid valve 2331 and the proximity sensor 43 to open every once in a while, so that the detection end 233 sprays water into the detection tube 4, and the sprayed high-pressure water can drive the pressure plate 41 to move upward in the detection tube 4; when the pressure plate 41 moves upward to the position of the proximity sensor 43, it means that the water pressure is normal, and the controller 12 will not control the alarm 121 to emit an alarm sound; when the proximity sensor 43 does not detect the pressure plate 41 moving upward to the height of the proximity sensor 43, it means that there is no water flow or the water pressure is insufficient. Subsequently, the controller 12 controls the alarm 121 to emit an alarm sound to warn that the fire hydrant 23 has a fault;

[0042] When the pressure plate 41 moves upward under the impact of high-pressure water flow, the pressure plate 41 can drive the upright column 61 to move upward. Subsequently, the upright column 61 can pull the piston rod 52 through the connecting rope 65, so that the piston rod 52 and the piston block 51 move away from the connecting hose 53, and the return spring 66 is compressed; at the same time, as the upright column 61 moves upward, the upper end of the upright column 61 can enter the piston cylinder 5 after passing through the connecting sleeve 54. When the water injection hole 612 at the upper end of the upright column 61 moves upward into the piston cylinder 5, the upper end of the upright column 61 can be embedded in the connection cover 78. The firing pin 79 in the connection cover 78 can push the push plate 77 downward, so as to drive the plugging block 72 in the cavity portion 71 to move downward through the connecting rod 75, and the plugging spring 73 is compressed. At this time, the water injection hole 612 and the water inlet passage 611 can be connected, and a part of the water flow acting on the pressure plate 41 can enter the water injection hole 612 along the water inlet passage 611, and this part of the water can enter the piston cylinder 5;

[0043] When the pressure plate 41 loses the impact of water flow and moves downward, first, the upper end of the column 61 leaves the connecting cover 78, and the plugging spring 73 can then push the plugging block 72 to plug the water inlet channel 611, thereby closing the water inlet channel 611 and avoiding water waste caused by water spraying out of the water injection hole 612. At the same time, the reset spring 66 can undergo elastic recovery. Subsequently, the reset spring 66 can push the piston block 51 to move towards the side close to the connecting hose 53, and the water flow in the piston cylinder 5 can be sprayed out from the nozzle 531 to clean the monitoring camera 3, thereby achieving efficient cleaning of the monitoring camera 3 by using the water in the detection pipe 4. Among them, the piston cylinder 5 extends obliquely downward towards the side of the connecting hose 53. When the column 61 moves downward and leaves the connecting sleeve 54, the inclined piston cylinder 5 can retain a part of the water, preventing all the water in the piston cylinder 5 from flowing out through the connecting sleeve 54. At the same time, it also makes the piston cylinder 5 contain both air and water. When the reset spring 66 pushes the piston block 51 to move towards the side close to the connecting hose 53, the water flow in the piston cylinder 5 will first be sprayed on the monitoring camera 3 to wash the surface of the monitoring camera 3. When the water flow is exhausted, the air in the piston cylinder 5 can be sprayed on the surface of the monitoring camera 3 with water droplets, thereby blowing away the water droplets on the surface of the monitoring camera 3 through blowing and avoiding the influence of water droplets on the shooting effect of the monitoring camera 3.

[0044] Meanwhile, when it is necessary to rotate the turntable 232 to open the valve body 231 of the fire hydrant 23, by using the prism 2321 provided on the side of the turntable 232 and the water injection hole 612 being an inner prism hole for cooperating with the prism 2321, the operator can unscrew the second cylinder 602 from the first cylinder 601 to disassemble the second cylinder 602 from the first cylinder 601. At the same time, the hook 651 of the connecting rope 65 is removed from the connecting ring 6022. At this time, the water injection hole 612 on the second cylinder 602 can be used for the prism 2321 to be inserted. Through the second cylinder 602, a force arm for rotating the turntable 232 can be formed, and finally, it is beneficial to conveniently rotate the turntable 232 to realize the multiple uses of the column 61.
