Description

Technical Field

[0001] The utility model relates to a lubrication pump and a lubrication grease storage container thereof. Background Art

[0002] In the field of dry oil lubrication, some large equipment often use multi-point pumps for centralized lubrication. Because large equipment has a large demand for grease, the grease storage container of the multi-point pump has a large capacity and is generally made of metal to meet the strength requirements. This metal grease storage container is not convenient for checking the remaining amount of grease, which is very inconvenient, especially when the grease is used up and cannot be discovered in time, the equipment will not be properly lubricated, resulting in increased wear of the equipment. For this reason, the traditional method is to install a laser sensor on the barrel cover to monitor the liquid level to achieve high and low liquid level alarms, but for different greases, some greases have light absorption and weak reflectivity, that is, the laser emitted by the transmitting end of the laser sensor sometimes cannot be received by the receiving end, resulting in false detection and failure to achieve normal liquid level alarms.

[0003] In addition, there is also a technology on the market that uses ultrasonic sensors to detect liquid levels, but this technology is mainly used to detect thin oil or other fluids. When the fluid falls on the ultrasonic sensor, it quickly flows down by its own weight. For the grease storage container of the multi-point pump mentioned above, it stores grease (also called dry oil) as a semi-fluid. The grease has high viscosity and poor fluidity. If it adheres to the ultrasonic sensor probe, the ultrasonic sensor will continue to send a high liquid level alarm signal. For the grease storage container of the multi-point pump, when replenishing the grease, it is generally necessary to open the container cover from the top and then manually fill the container with grease. During this process, it is difficult for the ultrasonic sensor probe on the container cover to avoid contact with the grease, and due to the structure of the ultrasonic sensor probe, it is difficult to clean the grease, so the ultrasonic sensor is also prone to failure and cannot detect the liquid level normally. Utility Model Content

[0004] The purpose of the utility model is to provide a grease storage container which can stably detect the grease liquid level; the purpose of the utility model is also to provide a lubrication pump using the grease storage container.

[0005] The technical solution of the grease storage container of the utility model is as follows: The grease storage container comprises:

[0006] Oil drums;

[0009] The manual cleaning device is installed on the liquid level detection module or the barrel cover and is used to wipe the lower surface of the probe.

[0010] Furthermore, the manual cleaning device includes a rotating shaft and a wiping rod rotatably mounted on the rotating shaft. An elastic wiping sleeve is sleeved on the wiping rod. When the wiping rod rotates around the rotating shaft, the wiping sleeve can rotate closely against the lower surface of the probe to wipe off the grease adhering to the lower surface of the probe.

[0011] Furthermore, the liquid level detection module also includes a protection box, in which a controller, a power module and a wireless communication module are arranged, and the ultrasonic sensor is control-connected to the controller.

[0012] Furthermore, an opening is provided in the center of the barrel cover, the protection box is mounted on a mounting plate with a perforation in the middle, the probe passes through the perforation, and the mounting plate is detachably connected to the barrel cover and covers the opening.

[0013] The technical solution of the lubrication pump of the utility model is as follows: the lubrication pump comprises a pump head assembly and a grease storage container installed on the upper part of the pump head assembly, and the grease storage container comprises:

[0014] Oil drums;

[0015] The barrel cover is detachably connected to the oil barrel;

[0016] The liquid level detection module is installed on the barrel cover and includes an ultrasonic sensor, wherein the ultrasonic sensor includes a probe that passes downward through the barrel cover and is arranged toward the inside of the oil tank, wherein the lower surface of the probe is a smooth plane and the lower surface of the probe is not lower than the lower surface of the barrel cover;

[0017] The manual cleaning device is installed on the liquid level detection module or the barrel cover and is used to wipe the lower surface of the probe.

[0018] Furthermore, the manual cleaning device includes a rotating shaft and a wiping rod rotatably mounted on the rotating shaft. An elastic wiping sleeve is sleeved on the wiping rod.

[0020] Furthermore, an opening is provided in the center of the barrel cover, the protection box is mounted on a mounting plate with a perforation in the middle, the probe passes through the perforation, and the mounting plate is detachably connected to the barrel cover and covers the opening.

[0021] Beneficial effects of the utility model: When a lubrication pump and its grease storage container of the utility model are used, compared with the traditional laser sensor detection method, the ultrasonic sensor can be used to improve the detection stability and reduce false alarms. The lower surface of the probe is set as a smooth plane. When grease adheres to the ultrasonic wave, the lower surface of the probe can be wiped clean very conveniently to avoid grease residue affecting the detection accuracy of the ultrasonic sensor. The setting of the manual cleaning device makes the cleaning process more convenient. In actual use, when the operator opens the cover to add grease to the oil barrel, the grease will inevitably adhere to the probe. Before covering the barrel cover, the manual cleaning device can be used to directly wipe and clean the lower surface of the probe, and the ultrasonic sensor can be used normally, which is very convenient and quick.
